Description

Deep sea anchor ingot device with deceleration wing gravity and anchor body composite

The invention provides a deep-sea anchor ingot device with a gravity wing with a reduction wing and an anchor body, in particular, a retarder wing and an anchor body provided by the anchor pedestal base, so as to generate resistance when the water flow passes through the reduction wing to slow the anchor slab The sinking speed of the foundation prevents the anchor ingot from quickly hitting the sea floor and causing damage; the anchor system can be applied to various types of seabed. When the seabed is gravel or sedimentary soil, it can be shoveled into the anchor ingot, and When the seabed is a rock, it can anchor the ingot against the uneven rock; thereby, the present invention can reduce the cost of the deep-sea anchor ingot and provide an excellent anchor force, which is beneficial to offshore facilities and ocean currents. Deployment of power generation equipment.

According to the ocean current, it is a large-scale seawater movement. Therefore, for the construction of offshore facilities and the deployment of ocean current power generation equipment, it is necessary to consider the direction and velocity of the ocean current, and to anchor the offshore facilities or ocean current power generation equipment to prevent damage. Ocean currents, wind and waves, and other factors drift away from the original waters.

The conventional anchor ingot method, as shown in Figure 1, can be roughly divided into the following six types:

1. Deadweight 10 (Dead weight): its anchoring force is formed by gravity and its friction with the sea floor.

2. Pile 20 (Pile): It uses a mallet or vibrator to press the pile 20 (such as a hollow steel pipe) into the sea floor to generate friction by squeezing the soil. Generally, the pile 20 needs to be pressed into a certain depth. Only with sufficient grip strength can we provide a certain degree of anchoring force.

3. Embedded drag anchor 30 (Drag embedment anchor): It is the most common anchor ingot method at present. It mainly uses part or all of it to be embedded in the seabed. The main source of the anchor ingot force is the resistance provided by the front end embedded in the soil. Its size is related to the embedding depth; this method is generally only suitable for providing horizontal anchoring force, and is not suitable for vertical pulling, because it is easy to pull it out of the soil when pulling vertically.

4. Suction anchor 40 (Suction anchor): It can be a hollow steel pipe like a pile, but the diameter of the pipe is relatively large. When the suction anchor 40 is pressed into the sea floor, a part of it will be left on the sea floor, and the interior will be pumped to the inside. The water is pumped out and capped to create a pressure difference between the inside and outside, so that the external water pressure provides the force of downward pressure, and it also has the friction between the soil and the steel pipe, which can provide horizontal and vertical anchoring force.

5. Gravity installed anchor 50: It uses its own gravity to fall quickly, which is generated by penetrating the soft sea floor and anchoring the anchor force. For the deeper sea floor, the faster the speed of free fall to the sea floor, Faster, the deeper the penetration depth, the greater the anchoring force can be generated, so it is suitable for deep sea with soft seabed anchoring ingots.

6. Vertical load anchor 60: It is similar to the above-mentioned embedded resistance anchor 30, but it is buried deeper. The anchor method can be changed, so it can provide vertical and horizontal anchor force. It is also suitable for subsea foundations. Uses of facility anchors.

However, due to the strong fluid flow in the ocean current seabed, there will be no sediment on the seabed. Most people found that they are rocky seabeds after actual exploration. They cannot embed anchors in the seabed. Therefore, the following five This kind of anchor bar method can only be applied to the soft sea floor with sediments, but not to the rocky sea bed. Gravity anchor 10 can be used because it provides the anchor bar force by gravity friction, but it requires a great deal of The weight has sufficient anchoring force. However, its manufacturing cost is extremely high, and it is extremely difficult to transport to the seabed for deployment in specific waters. In addition, during the deployment process, due to the rapid sinking speed in the deep sea, that is, Easy to cause collision with the sea floor and damage.

In view of this, our inventors have concentrated on further research on anchor ingots on the sea floor, and have begun research and development and improvement with a view to a better invention to solve the above problems, and after continuous testing and modification, the invention came out. .

That is, the purpose of the present invention is to solve the aforementioned problems. In order to achieve the above objectives, our inventors provide a deep-sea anchor ingot device with a reduction wing gravity and an anchor body composite, which includes: an anchor ingot base, at least A deceleration wing and at least one anchor body; an anchor ingot base for providing gravity; when the base is sunk in the sea, the gravity system is much greater than buoyancy to provide an anchoring force for heavy pressure and friction on the sea floor; the anchor ingot base The anchor body can be a floating body, such as a hull or a ship. The anchor ingot base is formed with a container inside, and the anchor rod base is provided with at least one water-conducting pipeline connected to the container side. The water guiding pipeline is provided with an on-off valve respectively, so as to facilitate floating and dragging on the sea surface, and when it is needed to be deployed, the on-off valve can be opened to allow water to enter the chamber of the anchor ingot base. Water enters and increases its density, and then sinks into the water.

The deceleration wing is arranged at the top of the anchor base, and the outer edge is arranged obliquely towards the anchor base. A resistance space is formed between the deceleration wing and the anchor base. When the anchor base is sinking into the water, the water flow will flow through the resistance space, and the resistance of the water flow will be caused by the deceleration wing, thereby slowing the sinking of the anchor base to a safe range, thereby preventing the anchor base from quickly moving. Damaged by impact with the sea floor; Further, the reduction wing further includes at least one main reduction wing and at least one auxiliary reduction wing; the position of the main reduction wing is higher than the auxiliary reduction wing, and the end of the auxiliary reduction wing extends beyond the anchor The side end of the ingot base increases the cross-sectional area, thereby increasing the resistance of the water flow, and has the function of diversion, so as to guide the water flow to the resistance space, so that the water flow generates resistance when passing through the main deceleration wing and the auxiliary deceleration wing, thereby achieving mitigation. The purpose of the sinking speed of the present invention; specifically, the anchor base is provided at the top with a support base, the support base forms the resistance space with the reduction wing, and the support base is opposite to the anchor base The main deceleration wing is closed at one end, and the auxiliary deceleration wing is respectively provided on both sides of the support base; at least one guide member is further provided between the deceleration wing and the anchor base, thereby further improving The function of diversion and support, and adjacent ones of the diversion members respectively form at least one diversion channel, the diversion channel is connected to the resistance space, and the auxiliary decelerating wing is at least partially received by the main Speed wing Shielding; provided whereby, in the process of the present invention is the sink, the flow resistance can be indeed lead to the reduction of the space between the wing and the anchorage base, in order to enhance water resistance.

The anchor body is pivotally located at the bottom of the anchor ingot base, so that when the gravel and sedimentary soil are on the seabed, the anchor body will shovel into the gravel and sedimentary soil; The anchor system is tilted in one direction, so it can withstand the protruding rock. Because the rock has good hardness, it can form a good anchor force with the anchor body; The anchor system is arranged in a cone shape, and a tip is formed at the end, so that the anchor body can be shoved into the gravel and the sedimentary soil.

The anchor ingot base is provided with at least one groove at the bottom, the groove is provided with a stopper portion on a side surface of the anchor, and the groove is pivotally provided at least at the upper end of the surface where the stopper portion is provided. One of the anchor bodies allows the anchor body to be restricted by its stopper to limit its angle, and can be beneficial against the protruding rock.

An elastic unit may be provided between the top of the anchor body and the top wall surface of the groove, and the elastic unit is configured to elastically abut against the anchor body, so that the anchor body abuts against the anchor body. The stopper portion cooperates through the weight of the anchor body and the elastic force of the elastic unit to make the anchor body protrude from the groove at the initial position to facilitate insertion into the rock bed gap or insertion into the sea floor.

The groove is further provided with at least one thrust element at an end opposite to the stopper, so that when the anchor base sinks, the anchor body will be subjected to water pressure to elastically compress the elastic unit. If the anchor body is opposite to the end of the stopper, it abuts against the bottom of the thrust element.

The pipe body is arranged at the bottom of the anchor ingot base, and the bottom of the anchor ingot base is concavely provided with at least one receiving groove to accommodate the pipe body. The pipe body may be a circular steel pipe, and the diameter of the pipe body is One end of the side edge is fixed to the receiving groove, and the other end of the radial side edge of the pipe body protrudes from the receiving groove and is located at the bottom of the anchor ingot base, thereby further reducing the anchor. The strength of the ingot base hitting the sea floor is designed to further protect the safety of the base.

Therefore, the present invention uses the gravity of the anchor ingot base, so that when the seabed is rigid when settling to the seabed, it will press the seabed to deform it, thereby facilitating the anchor body to abut or shovel into the seabed; If the bed is not rigid, the anchor body can be shoved into the sea bed, and the gravity of the anchor ingot base will make the sea bed shoved into by the anchor body more compact, so that the soil or gravel of the sea bed cannot be anchored. The turning of the body causes the anchor body to break away from the sea floor, thereby providing an excellent anchoring force, and the gravity required by the anchoring base can be much smaller than the conventional gravity anchor that provides gravity, which can greatly reduce the cost of installation and deployment.

Regarding the technical means of our inventors, several preferred embodiments are described in detail below in conjunction with the drawings, for the purpose of understanding and agreeing with the present invention.

Please refer to FIG. 2 to FIG. 4 first, the present invention is a deep-sea anchor ingot device with a reduction wing gravity and an anchor body composite, which includes: an anchor ingot base 1; Anchor spindle force is achieved by heavy pressure and friction; in order to facilitate the transportation and deployment of the anchor spindle base 1, in a preferred embodiment, the anchor spindle base 1 is a floating body. The anchor base 1 may be a hull or a floating object provided in a ship shape. As shown in FIG. 4, the anchor base 1 may be floated on the sea surface, so that other ships can tow the anchor base 1 on the sea surface. And the anchor base 1 forms a container 11 inside, which is similar to the ballast of a conventional ship, and its setting is a conventional ship technology, so it will not be repeated here; the anchor base 1 At the side, at least one water guiding pipe 12 communicating with the container 11 is provided, and each of the water guiding pipes 12 is provided with an on-off valve 13; and as shown in FIG. 4, when the anchor base 1 is initially towed When the water in the chamber 11 of the anchor base 1 has not yet entered the water, and the on-off valve 13 is closed, seawater will not be able to enter the chamber 11 to make the anchor base 1 dense. Less than the density of seawater, so it can float on the sea surface; and as shown in Figure 5, when the anchor base 1 needs to be sunk, the on-off valve 13 can be opened, so that seawater can pass through the water-conducting pipeline 12 Enter the chamber 11 of the anchor base 1 to increase the weight and density of the anchor base 1 so that the density of the anchor base 1 is much greater than the density of the seawater, and then it can sink into the seawater, which sinks and floats. The principle is the same as the ballast of the conventional ship technology. As far as the on-off valve 13 is concerned, it is known that the valve body used to open and close the waterway can be operated by personnel to open and close; for example, the on-off valve 13 can be The electronic valve body can be opened or closed by remote control. In another embodiment, the on-off valve 13 can also be a butterfly valve or a ball valve, so that the staff can enter the chamber 11 and open the on-off valve 13 manually. Then, before the water in the chamber 11 of the anchor base 1 caused the anchor base 1 to sink, the staff escaped from the chamber 11 to the ship towing the anchor base 1 as soon as possible. This design also needs to provide a passage for workers to leave in the container room 11 (not shown). In consideration of the safety of the workers, it is better to use the on-off valve 13 as an electronic valve body. The specific structure is a known technology, so it will not be repeated here; in order to improve the stability when sinking, so that the anchor ingot base 1 is not easily overturned by the sinking and the influence of the ocean current, so an embodiment In the system, a balance device can be further installed on the anchor base 1 so that the anchor base 1 can maintain the stability of the sinking. The balance device is a well-known technology widely used in ships, so it will not be repeated here. .

At least one speed reducing wing 2 is disposed at the top of the anchor base 1, and a resistance space 3 is formed between the speed reducing wing 2 and the anchor base 1; thereby, the anchor base 1 is sunk. At this time, the water can flow to the resistance space 3 to increase the fluid resistance, thereby reducing the sinking speed to a safe range; in one embodiment, the outer edge of the deceleration wing 2 faces the anchor base 1 The direction is tilted. As shown in Figure 2, the way of setting will make it difficult for the water flow to exit the resistance space 3, which can help increase the fluid resistance. In a preferred embodiment, in order to effectively increase the speed of the retarder 2 The cross-sectional area further enhances fluid resistance, so the reduction wing 2 further includes at least one main reduction wing 21 and at least one auxiliary reduction wing 22; and the position of the main reduction wing 21 is higher than the auxiliary reduction wing 22; The end of the auxiliary decelerating wing 22 is extended beyond the side end of the anchor base 1 to increase the overall cross-sectional area of the decelerating wing 2, and the auxiliary decelerating wing 22 is also used to guide the water flow into the resistance space 3. To increase the overall water flow resistance; specifically, for the deceleration wing 2 It is provided that the anchor base 1 is vertically provided with a support base 14 at the top end. The support base 14 forms the resistance space 3 between the reduction wing 2 and the support base 14 at one end relative to the anchor base 1. The main reduction wing 21 is provided in a closed manner; and the auxiliary reduction wing 14 is respectively provided on both sides of the support base 14.

In order to reduce the moment of water impact caused by the sinking of the anchor ingot base 1 by the auxiliary deceleration wing 22 and effectively improve the overall fluid resistance, in a preferred embodiment, the auxiliary deceleration wing 22 and the anchor At least one flow guiding member 15 is provided between the ingot bases, and the adjacent flow guiding members 15 respectively form at least one flow guiding channel 151, and the flow guiding channel 151 is connected to the resistance space 3; As shown in Figure 6, during the sinking of the anchor base 1, the water flow will first be resisted by the auxiliary decelerating wing 22, and follow the deflection angle of the auxiliary decelerating wing 22 to flow to the main via the diversion channel 151 The resistance space 3 between the deceleration wing 21 and the anchor base 1; and to increase the resistance of the water flow so that the water flow is less likely to flow out of the resistance space 3, it is preferable that the auxiliary deceleration wing 22 is at least partially subject to the main The deceleration wing 21 is shielded, so the water flow passing through the diversion channel 151 will not directly flow out, but will be blocked by the main deceleration wing 21 and finally discharged from the periphery of the main deceleration wing 21; With this design, the cost can be greatly improved. Invent the overall water flow resistance; and when the water flow resistance is greater than the overall net gravity, that is Slow the rate of subsidence.

Because the present invention considers the impact force between the anchor base 1 and the sea floor, it is assumed that the weight of the anchor base 1 after it has completely entered the water is 500 tons, and the sinking speed is about 3 m / s. In the case of decelerating wing 2, considering different types of seabeds, their different stopping times and impact forces are estimated as shown in Table 1 below:

Among them, the impact force F _impact is the sum of the sea floor rebound force F _res and the anchor base 1 weight W; the sea floor rebound force F _res is shown in the following mathematical formula 1:

It can be seen from Table 1 that the impact force generated when the anchor base 1 hits the rough and hard seabed will reach about 1264.53 metric tons. If the impact force is too large, there is a concern that the anchor base 1 will be damaged.

The relationship between the fluid resistance F _D and the sinking speed V is shown in the following mathematical formula 2:

Among them, C _{D 12} is the resistance coefficient of the anchor ingot base 1 provided with the speed reduction wing 2, and because of the way of the present invention, this value is relatively large; ρ is the seawater density; A ₁ is the cross-sectional area of the anchor ingot base 1. A ₂ is the cross-sectional area of the reduction wing 2; and the equilibrium speed at which the fluid resistance is equal to the weight of the anchor base 1 is the sinking speed V, as shown in the following mathematical formula 3:

Among them, V ₁₂ is the sinking speed of the anchor base 1 with the reduction wings 2.

If the reduction wing 2 is not provided, it is shown in the following mathematical formula 4:

Among them, C _{D 1} is the resistance coefficient of the anchor ingot base 1 without the reduction wing 2, and its value is small, because the bottom structure of the ship is usually set to be streamlined to reduce the resistance; V ₁ is the anchor ingot base without the reduction wing 2 The sinking speed of Block 1; and when the mathematical formula 3 is equal to the mathematical formula 4, the relationship between the sinking speed V ₁₂ and V ₁ can be obtained, as shown in the following mathematical formula 5:

It can be known from the above mathematical formula 5 that the sinking speed V ₁ of the anchor ingot base 1 without the reduction wing 2 will be much higher than the sinking speed V ₁₂ of the anchor ingot base 1 with the reduction wing 2. There is a concern that the speed V ₁ is too fast and the anchor base 1 is damaged. Therefore, a reduction wing 2 must be provided to reduce the sinking speed.

The design of the front deceleration wing 2 can reduce the sinking speed of the anchor base 1 to reduce the impact force of the anchor base 1. In another embodiment, in order to further protect the safety of the anchor base 1, As shown in Figs. 2 to 7, a design for adding anti-collision protection to the bottom of the anchor base 1 is provided, so that at least one receiving groove 16 is recessed upward from the bottom of the anchor base 1; and, at least one tube The body 161 may be a circular steel pipe, and the body 161 may be a single arrangement or a plurality of bodies 161 arranged side by side; one end of a radial side edge of the body 161 is fixed to the body. The receiving groove 16 is located at the other end of the radial side edge of the pipe body 16 protruding from the receiving groove 16 and is located at the bottom of the anchor base 1; The space of the body 161 is deformed, so the width of the receiving groove 16 can be slightly larger than the diameter of the pipe body 161. For the positioning of the pipe body 161 in the receiving groove 16, it can be welded, riveted, Positioning by locking and other methods is a well-known technique, so it will not be repeated here.

Therefore, as shown in Figs. 6 and 7, when the bottom of the anchor base 1 is about to hit the sea floor, the pipe body 161 contacts the sea floor first because the pipe body 161 projects from the bottom of the anchor base 1. And bear the impact force of the anchor base 1 when it hits the sea floor, so the pipe body 161 will be deformed by the force, thereby absorbing most of the impact energy, and the buffer effect can be achieved, thereby preventing the anchor base 1 from being hit And damage; its mass-energy conservation system is shown in the following mathematical formula 6:

Among them, M _boat is the weight of the anchor base 1, V _fall is the sinking speed, e is the unit destruction energy of the pipe body without side support, and M _pipe is the unit length of the pipe body 161.

With this, the anchor ingot base 1 with a weight of 1,000 metric tons (tons) after full water penetration, assuming its sinking speed in seawater is about 3.5 m / s, the required length of the pipe body 161 and its absorbability The percentage of impact energy is shown in Table 2:

As can be seen from Table 2 above, when the pipe diameter D is 660.4mm, if the length of the pipe body 2 is 123.24, it can absorb 52.7% of the impact energy. Generally speaking, 1,000 tons of deep-sea mooring bases after completely entering the water Seat (such as the anchor ingot base 1 of the present invention), the maximum length of which can be installed to the pipe body 161 is 65m, in other words, the present invention can absorb about 26.35% of the impact energy under the same size, in accordance with the aforementioned setting of the reduction wing 2, The impact force between the anchor ingot base 1 and the sea floor can be greatly reduced, thereby effectively protecting the anchor ingot base 1 from being easily damaged by impact.

At least one anchor body 4 is pivotally disposed at the bottom of the anchor ingot base 1 and is used to fix the anchor ingot base 1 to the sea floor when the anchor ingot base 1 is settled to the sea floor.

In one embodiment, the anchor body 4 is inclined in one direction. In a specific embodiment, the inclination of the anchor body 4 is provided with at least one groove 17 at the bottom of the anchor base 1. The groove 17 is provided with a stopper portion 171 on the side surface of one side, and at least one of the anchor bodies 4 is pivotally provided at the upper end of the groove surface on which the stopper portion 171 is provided; The anchor body 4 may indeed protrude from the groove 17, and at least one elastic unit 18 may be further provided. One end thereof is provided on the top wall surface of the groove 17, and the other end is correspondingly connected to the anchor body 4. On the top, the elastic unit 18 is configured to elastically abut against the anchor body 4 so that the anchor body 4 can protrude from the groove 17 and form an angle θ _A ; in another embodiment The groove 17 is further provided with at least one thrust element 19 at one end opposite to the stopper 171. When the elastic unit 18 is elastically compressed by the force, the anchor body 4 is opposite to the stopper The end of 171 is able to abut against the bottom of the thrust element 19 to prevent the anchor body 4 from being excessively retracted into the groove 17 and also to avoid affecting the elastic force of the elastic unit 18, and this The angle of the anchor body 4 at this time is θ _B. In addition, the receiving groove 16 and the groove 17 can be arranged at intervals on the bottom of the anchor base 1 as shown in FIG. The pipe body 161 of the accommodating groove 16 buffers, and the anchor body 4 installed in the groove 17 performs anchoring.

Therefore, as shown in FIG. 8, in the initial position, the anchor body 4 is pushed up by the elastic unit 18 in the initial position, so that the anchor body 4 protrudes from the groove 17 to facilitate insertion into the rock bed gap or insertion. The seabed; and when the anchor base 1 is settled on the seabed, as shown in FIG. 9, the anchor body 4 may be pressed by the elastic unit 18 with the possibility of water pressure, so that the anchor body 4 is retracted into the groove. 17, the thrust element 19 can be used to limit the position where the anchor body 4 can be retracted into the groove 17, and when the anchor base 1 approaches the sea floor to reduce the water pressure, as shown in FIG. 8 It is shown that the anchor body 4 will be abutted by the elasticity of the elastic unit 18 and protrude from the groove 17 again; in another embodiment, if the elasticity coefficient of the elastic unit 18 is sufficiently large, it may not be caused by water pressure. The anchor body 4 is retracted into the groove 17 and the anchor body 4 is kept protruding from the groove 17 during the settlement process; The setting and selection can be considered according to the state of the water pressure on the anchor body 4, which is also a known technology, so it will not be repeated here.

When the anchor ingot base 1 settles to the sea floor 5, the anchor ingot base 1 is dragged in the anchoring direction of the anchor body 4 through a ship on the sea surface. The purpose is that when the seabed 5 is gravel or sedimentary soil At this time, as shown in FIG. 10, the anchor body 4 can be partially shoved into the sea floor 5 by the abutment of the elastic unit 18, or placed on the surface of the sea floor 5, and the anchor body is made by the drag force T 4 Under the action of the elastic force of the elastic unit 18, the shape of the anchor body 4, and the drag force T, as shown in FIG. 11, the shovel is surely shoveled into the sea floor, so that the angle of the anchor body 4 is θ _C , and The bottom of the anchor body 4 is pressed against the stopper 171 to make the anchor body 4 firmly anchored. Therefore, it is preferable that the anchor body 4 is set in a cone shape and a tip is formed at the end to facilitate the anchor body. 4 shovel into the seabed, and after the anchor body 4 is shoveled into the seabed, due to the weight of the anchor ingot base 1, the gravel or sedimentary soil around the location of the anchor body 4 shovel into the seabed is denser by heavy pressure, which can prevent The loose rock or sedimentary soil is lifted up and the anchor body 4 loses its anchoring ability; as shown in FIG. 12, if the seabed 5 ′ is a hard rock, the pivoted anchor body 4 will be subject to elasticity. 18 of the elastic force, and according to the undulating contour of the rock and pivot, while dragging by the anchor body so that the tip 4 may abut against the side end portion of the projecting rock to form an anchor.

From the above description, it is obvious that regardless of the type of the seabed 5, 5 ', the present invention combines the gravity of the anchor ingot base 1 and the frictional force with the seabed under heavy pressure, and combines the abutment or shovel of the anchor body 4. Into the seabed 5, 5 ', and then in the case where the gravity of the anchor ingot base 1 is much less than the conventional gravity anchor, an excellent anchor ingot force can be achieved; therefore, if offshore facilities or ocean current power generation equipment is required, There is no need to consider the type of the seabed in the sea area to be laid. The anchor ingot can be carried out only through the present invention. In the process of the anchor ingot, there is no need to perform high-cost underwater operations. It is obvious that the present invention is indeed applicable and The effect of low cost.

In summary, the technical means disclosed in the present invention can effectively solve problems such as knowledge, and achieve the intended purpose and effect.
