Description

 Guarding sand system and method

 The invention relates to water and sand adjustment technology, in particular to a sand disturbance system and a sand disturbance method performed by the system. Background technique

 Since ancient times, "more water and less sand, imbalance of water and sand" has become the root cause of flooding in the Yellow River. The Yellow River carries 1.6 billion tons of sediment into the downstream each year, of which 400 million tons are deposited in the downstream riverbed, making it an average of 10 centimeters per year. Uplifting, the current downstream riverbed is 4-6 meters above the river surface, forming a world-famous "overhanging river".

In view of the actual situation of the Yellow River, in recent years, China has proposed the control measures of “water transfer and sand adjustment”, that is, by using the existing kinetic energy of river water, supplemented by artificial disturbance of riverbed sediment, to achieve riverbed undercut, so as to maximize sand transport into the sea. Among them, the artificially disturbed riverbed sediment is mainly used to carry out high-pressure impact above the sedimentation surface of about 0.5 m from the silt-discharging vessel loaded with the air compressor and the high-pressure nozzle, and the silt in the area is fully disturbed. When the high-pressure nozzle of this type of sand-slipping vessel exerts a high-pressure impact on the sediment-laden surface, the impact area is small. For the large-scale sedimentation section of the Yellow River, the effect of disturbing sand is not obvious. Moreover, the prior art generally only treats certain locations where sedimentation is severe, and the agitated sand deposits into the next section. Therefore, the goal of completely controlling sediment can not be achieved. To achieve the control of the entire river, the cost will be quite large, and it is difficult to achieve complete cure. Summary of the invention It is an object of the present invention to provide a sand disturbing system and method for enhancing the effect of disturbing sand and curing water problems. To achieve the above object, the present invention provides a sand disturbing system, comprising: a sand disturbing ship, the sand disturbing ship comprising:

 a floating body floating on a stream of water, at least one in number;

 a baffle disposed on the floating body in an amount of at least one, the baffle being inserted into the water flow during sand disturbance, and the edge of the baffle having a distance from the river bed for flowing in the water The sediment on the river bed is disturbed when the spacing is exceeded.

 To achieve the above object, the present invention also provides a method for disturbing sand, comprising:

 Inserting a baffle provided on the floating body of the sand trapping vessel into the water flow, the edge of the baffle having a distance from the riverbed;

 The baffle drives the floating body to flow downstream under the impeding of the water flow, and the water flow disturbs and washes away the sediment when passing through the spacing.

 According to the above technical solution, the baffle of the present invention blocks the water flow, so that the water flows through the interval between the edge of the baffle and the river bed to rapidly flow to disturb and wash away the sediment, thereby overcoming the high pressure of the prior art sand disturbing ship. When the nozzle exerts a high-pressure impact on the sedimentation surface, the impact area is small. For the large-scale sedimentation section of the Yellow River, the technical effect of disturbing sand is not obvious. Moreover, as the floating body travels, sand can be adjusted in a long area of the river to completely control the sedimentation problem. The invention can enhance the effect of disturbing sand, cure the flood, and realize the simple method, and is easy to promote and apply in the Yellow River and various waters. DRAWINGS

According to the principle that the water carrying capacity of the water flow is proportional to the square of the water flow speed, if the angle between the baffle 2 and the water flow direction is increased, the distance between the edge of the baffle 2 and the bottom of the river bed becomes smaller, and the water flow velocity passing through the gap becomes smaller. If it is increased, the sand disturbing effect of the sand disturbing system of the present invention is more obvious, and the speed of the bottom of the riverbed is faster. Similarly, as shown in FIG. 2, it is a cross-sectional view of the river channel of the sand disturbing principle of the sand disturbing system of the present invention. When the angle between the baffle 2 and the water flow direction is increased, the distance between the edge of the baffle 2 and the two sides of the river bed becomes smaller, and the water flow velocity passing through the distance between the two sides is correspondingly increased, and the sand disturbing ship of the present invention is used to disturb the river bed. The width of the two sides is faster.

 Sand mitigation system embodiment 1

FIG. 3 is a schematic structural view of a first embodiment of a sand-slipping system according to the present invention. The system can be disposed in the Yellow River waters to utilize the directional water flow in the river to disturb the sand. The system may in particular comprise a wheel 3 and a sand-carrying boat consisting of a floating body 1 and a baffle 2, which is connected to the wheel 3 via a flexible chain 4. Among them, the wheel 3 is fixedly arranged with respect to the water flow, and can be fixedly inserted into the river bottom or fixed to the dam or the shore. The sand disturbing ship specifically includes: at least one floating body 1 floats on the water flow, specifically, the common hull can be used as the floating body 1; at least one baffle 2 is disposed on the floating body 1, and when the sand is disturbed, the baffle 2 is inserted into the water flow The direction of the baffle 2 is at an angle with the flow direction of the water flow, the angle is greater than 0 degrees and less than or equal to 90 degrees, and the baffle 2 is used to drive the floating body 1 to run downstream under the driving of the water flow to control the floating body. The speed of 1 is less than the speed of the water flow. There is also a gap between the edge of the baffle 2 and the river bed, and when the floating body 1 is running, the water flow is squeezed and rapidly flows through the distance, from It is able to stir up the sediment on the riverbed to disturb the sand, and the uplifted sediment can be washed away.

 In the present embodiment, the floating body 1 is connected to the wheel 3 by a flexible chain 4, one end of the flexible chain 4 is fixedly connected to the floating body 1, and the other end of the flexible chain 4 is wound around the wheel 3. When the floating body 1 is driven by the water flow, the drag chain 4 drives the wheel 3 to rotate. In a specific application, the advantage of using the flexible chain 4 and the wheel 3 is that the floating body 1 can be controlled, and the floating body 1 can be retracted to the starting point by winding the flexible chain 4 after the floating body 1 travels for a certain distance.

 The sand disturbing process of the sand disturbing system of the embodiment is specifically: first inserting the baffle into the water flow, and the baffle drives the floating body to run along with the water flow; the baffle blocks the water flow, so that the water flows through the edge of the baffle The spacing from the riverbed disturbs and washes away the sediment of the riverbed; the sediment of the riverbed through which the floating body passes can be disturbed and washed away.

 4 Yousha method embodiment

 FIG. 10 is a flowchart of a specific embodiment of a sand-slipping method according to the present invention. The method may be specifically implemented by using an embodiment of the sand-splitting system of the present invention, which includes the following steps:

 Step 1 00, inserting a baffle provided on the floating body of the sand disturbing ship into the water flow, the edge of the baffle having a distance from the river bed, and the baffle has an angle with the direction of the water flow;

 Step 200: The baffle drives the floating body to flow downstream under the driving of the water flow, and the water flow is blocked by the baffle, disturbs through the spacing and washes away the sediment.

Wherein, the floating body may be connected to one end of a flexible chain, and the other end of the flexible chain is fixed on a wheel disc fixedly disposed with respect to the water flow, and the flexible chain is wound on the wheel. Therefore, when the baffle is driven by the water flow to drive the floating body to run downstream, the step 300 can be performed, the flexible chain wound by the floating body is loosened, and the dragged flexible chain drives the wheel to rotate. The function of connecting the flexible chain is to stop When the sand is disturbed, the floating body is conveniently recycled to the starting point.
