Description

  TECHNICAL FIELD The present invention relates to a floating water purifier that purifies water by causing a circulating flow from a bottom to a water surface by mooring in a floating state in a lake or the like and stirring the water surface with a blade.

  Conventionally, as shown in Patent Document 1, a floating water purifier installed in a floating state in a pond, a dam, a lake, an entering sea, or the like is already known. This water purifier rotates a plurality of blades extending in the radial direction from the rotation drive unit and stirs the water surface, causing a water flow spreading on the water surface to guide a large amount of water from the bottom of the water to the surface of the water. It causes the circulating flow to flow and purify the water.

The floating water purifier supports a rotary drive unit that rotates the blade plate in a floating state on the surface of the water by a floating structure of the float base, and the blade plate is integrated with a blade arm that is attached and fixed to the drive shaft of the rotary drive unit. It is the composition provided in. The rotation drive unit is connected to a plurality of anchors installed on the ground at the bottom of the water via a float base and a flexible anchoring member such as a wire rope or a chain, and is supported in a moored state.

I have to.
Japanese Patent No. 3360075

  The floating water purifier shown in Patent Document 1 floats and supports a rotary drive unit that rotates and drives the blades by the floating structure of the float table on the surface of the water. Since it is supported so that it can follow and operate | move, there exists an advantage which can be rotated in the state maintained by the predetermined stirring attitude | position which submerged the blade board on the water surface. However, when a specific blade is lifted locally by a wave among a plurality of blades, the blade that is located on the other side of the blade arm that is supported in a fixed state on the drive shaft sinks deeply into the water. Be in posture.

  Therefore, the slats rotated in the above-described sinking posture are subjected to a large scratching resistance in the water, and the rotation of the slats is disturbed and the formation of the circulation flow is easily disturbed. Further, since the opposed blade plate and blade arm receive a large bending moment in the vertical direction with the drive shaft as a fulcrum, there is a drawback that a blade arm reinforcement structure is required and the weight of the device is increased.

  Furthermore, when a large change in water level is abruptly received due to strong winds, high waves, etc., the mooring member increases in slack with the large downward movement of the floating water purifier, loses the mooring action, and no longer supports the stir resistance. As a result, a plurality of mooring members are rolled under the rotational drive unit and entangled in an intersecting manner, making it impossible to moor the floating water purifier at an appropriate position, and by contact with the entangled mooring members. There are problems such as damage to the slats and the rotary drive.

  Therefore, when the fulcrum part that floats and supports the rotation driving part of the blade plate as shown in FIG. 3 of Patent Document 1 is to be connected from the anchor by one flexible anchoring member, the anchoring member rotates. It is twisted by the rotational reaction force of the drive unit, and the mooring length is shortened to cause the blade arm and the rotary drive unit to sink in water sequentially.

  For this reason, the floating water purifier is anchor-supported by a plurality of flexible mooring members arranged in different directions, so that complicated floating installation work is required, and the mooring member and mooring work are expensive. There is also a problem.

  The floating type water purifier for solving the above-mentioned problem firstly provides a plurality of blade plates 3 in a radial direction on the rotating body 10 of the rotation drive unit 2 and supports them in a floating state. In the case of purifying the water by generating a circulating flow of water by rotating around 2, the blade plate 3 is supported so as to be movable up and down with respect to the rotating body 10, and the blade 3 is submerged in the water surface. It features a floating structure that can be floated on.

  Secondly, the blade wall plates 25 and 25 attached to the tip end portion of the blade arm 22 supported by the rotating body 10 so as to be swingable and rotatable by a fixture 23 such as a bolt, and the blade wall plates 25 and 25. The wing plate 3 having a floating structure is constituted by a plate-like float member 26 supported therebetween.

  Thirdly, the fixing case 15 that accommodates and supports the rotation driving unit 2 of the rotating body 10 and the anchor 20 that is fixed to the ground of the water bottom are connected by a rod-shaped connecting rod 19 having engaging portions 17 at the upper and lower ends. It is characterized by that.

  Fourth, the water purifier 1 is provided with a material supply unit 7 for supplying materials such as algae, bait, or minerals into the water, and the material is supplied from the material supply unit 7 into the water to be diffused on the circulating flow. It is characterized by that.

  The floating water purifier of the present invention configured as described above moves the slats of the floating structure floating on the water surface in a posture to follow the wave with the rotator side as a fulcrum and moves up and down independently. It can be prevented from sinking deeply from the water surface. Further, each blade can maintain an appropriate stirring posture and perform an efficient stirring operation.

  By supporting the plate-like float member between the blade wall plates, a floating structure blade plate having strength at the tip of the blade arm can be manufactured with a simple configuration. Further, the blade plate formed of the plate member can be easily extended and cut in the blade length direction and can easily adjust the buoyancy.

  By connecting the fixed case of the rotation drive unit and the anchor fixed to the ground of the bottom of the water to the upper and lower ends of the rod-shaped connecting rod by the engaging part that becomes the joint part, the fixed case is resisted against the rotational reaction force of the blades. It can be supported non-rotatably. In addition, since the water purifier can be moored by one connecting rod, floating installation work and the like can be easily and inexpensively performed.

  In addition, by providing a material supply unit that can supply algae, bait, minerals, or other materials to the water purifier, the material can be supplied from the material supply unit to the water and spread in a circulating flow. It is possible to easily promote the functions possessed by.

  An embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a floating water purifier according to the present invention (hereinafter simply referred to as a water purifier). This water purifier 1 is installed in a floating state in a wide pond, dam, lake, inland, etc. like the conventional one, and stirs the water surface by a plurality of blades 3 extending radially from the rotary drive unit 2. Can do. The water purifier 1 can improve the aquatic environment and perform water purification by generating a water flow that spreads over the water surface with a little energy, guiding a large amount of water from the water bottom to the water surface, and generating a circulating flow that flows over the water bottom.

  The water purifier 1 according to the first embodiment of the present invention shown in FIG. 1 supports a floating central portion of a rotary drive unit 2 having a floating structure moored by an anchor structure 4 to be described later from the bottom of the water bottom. By rotating the slats 3, a circulating flow with the mooring part as the center can be generated.

  And the water purifier 1 of the example of illustration is equipped with the material supply part 7 which consists of the growth apparatus 5 which grows and supplies algae, the material supply apparatus 6 which accommodates and supplies a mineral, etc. on land, and water bottom with respect to this material supply part 7 The algae, feed, minerals, and the like conveyed by the supply control operation of the material supply unit 7 can be supplied into the circulation flow.

  The structure of each part of the water purifier 1 will be described. The rotation drive unit 2 of the water purifier 1 includes a drum-shaped rotation body 10 provided with a plurality of blade plates 3 extending in a radial direction by a swing support structure 9, and a center portion of the rotation body 10 is attached to and detached from a drive shaft 11. A drive motor 12 that is mounted and supported so as to be rotated, and a fixed case 15 that accommodates and fixes the drive motor 12 at the center, and that fills and accommodates a float member 13 made of a foamed plastic material along the inner periphery. Is done.

As a result, the fixed case 15 constitutes a float-structured float in which the float member 26 is covered by the rotating body 10, and the engaging portion 17 of the anchor structure 4 is attached to the anchor ring 16 protruding from the center of the bottom surface. It is connected so that it can be operated interchangeably and moored in a floating state on the water surface.
The anchor structure 4 is provided with anti-arc-shaped engaging portions 17 at the upper and lower ends of the rod-shaped connecting rod 19, and the lower engaging portion 17 is anti-arc-shaped protruding from an anchor 20 fixed to the ground of the water bottom. The mooring ring 21 can be connected to be able to operate in a flexible manner.

  With this configuration, the fixed case 15 and the anchor 20 are connected by the engaging portion 17 and the mooring ring 16 that form a universal joint at the upper and lower ends of the rod-shaped connecting rod 19, so that the water purifier 1 can be connected to the normal water surface. When making it float, it connects as a length which makes the connection rod 19 become the attitude | position which inclines beforehand. As a result, each vane plate 3 is rotated by the drive motor 12 while maintaining a stirring posture in a state where each vane arm 22 is submerged away from the water surface.

  When the vane plate 3 rotates, the fixed case 15 twists and applies a load to the connecting rod 19 due to the rotational reaction force of the vane plate 3. The connecting rod 19 tilts the water purifier 1 via the universal joint portion against this load. Etc., such that the posture can be changed and supported, and torsionally supported. Therefore, since the connecting rod 19 does not shorten the connecting distance due to the rotational load, it can be moored by one mooring member.

  Further, when the water purifier 1 is greatly floated and raised due to changes in the water level, waves, and undulations, the connecting rod 19 swings and follows in the standing and tilting directions, so that the water purifier 1 is smoothly stirred without being hindered from rising and descending. The posture can be maintained and floating on the water surface can be followed, and the formation of the circulation flow can be continued smoothly.

  Further, since the water purifier 1 can be moored by a single connecting rod 19, it is not necessary to support anchors from different directions by a plurality of mooring members having flexibility unlike the conventional one, and the water purifier 1 Can be done easily and inexpensively. The connecting rod 19 can have a slide joint structure, and in this case, the support length can be freely changed.

  Next, the blade structure installed in the rotating body 5 will be described. As shown in FIGS. 2 to 4, the blade plate 3 includes blade wall plates 25 and 25 that are attached to a tip end portion of a blade arm 22 made of a hollow member such as a square pipe by a fixture 23 such as a bolt, It is comprised from the plate-shaped float member 26 etc. which are supported between the blade wall plates 25 and 25. FIG.

  The vane wall plates 25 and 25 are mounted and fixed to the vane arm 22 by the fixture of the fixture 23 in a state where the iron plate or the plastic plate which is symmetrical in cross section in the left-right direction is abutted and the float member 26 is sandwiched inside. . At this time, the opening ends formed before and after the blade wall plates 25, 25 are closed by the cover plate 25a, and the blade plate 3 is sealed to protect the float member 26 inside.

In the blade structure configured as described above, since the blade plate 3 installed at the tip of the blade arm 22 includes the float member 26 and has buoyancy, the bulk of the float member 13 installed on the rotation drive unit 2 side is large. The size of the apparatus can be reduced.
Further, the float member 26 and the blade wall plates 25, 25 formed in a plate shape can be easily extended or cut in the blade length direction, and the length of the blade plate 3 can be easily changed. Can do.

Accordingly, when manufacturing various water purifiers 1 with different diameters of the blades 3, the lengths and buoyancy of the blades 3 can be easily adjusted, and the assembly work at the installation site can be easily performed. be able to.
In addition, the blade 3 is filled with a foamed plastic material in a hollow bag structure of the blade wall plate 25, or a hard wall member having weather resistance is attached to the surface of the plate made of the foamed plastic material. A coated blade structure can also be used.

  Further, as shown in FIG. 3, the blade structure is provided with a mounting bracket 27 formed in a downward U-shape on the upper surface of the rotating body 5, and with the base of the blade arm 22 inserted into the mounting bracket 27, It is configured to be connected by a support pin 29 on the horizontal axis. At this time, the blade arm 22 restricts the play in the left-right direction by the mounting bracket 27 and freely swings in the up-down direction with the support pin 29 as a fulcrum. The swinging rotation of the blade arm 22 and the rotation restriction thereof are performed by the gap between the upper end of the mounting bracket 27 and the rotating body 10.

  Due to the floating structure, the blade plate 3 configured as described above can be floated in a state where the blade arm 22 is submerged to a position where the blade arm 22 is separated from the water surface. Can be operated vertically. That is, when an arbitrary slat 3 is moved up by a wave, the slat 3 positioned on the other side is actuated downward (seesaw operation) with the rotation drive unit 2 side as a fulcrum like a conventional one, and completely immersed in water. It is possible to suppress submersion (sinking).

  Therefore, rotation in a state where the blade plate 3 and the blade arm 22 are deeply submerged from the water surface can be prevented, and energy saving operation of the water purifier 1 can be promoted. In addition, the water purifier 1 maintains each of the blade plates 3 in a properly swirling posture (submerged posture) while minimizing shaking on the rotary drive unit 2 side, and smoothly performs an efficient stir operation.

  Further, when the water purifier 1 is installed in the water of the installation site, the rotary drive unit 2 can be supported and moored by the connecting rod 19 with each blade plate 3 removed, and the blade plate 3 is water surface by its own buoyancy. Therefore, the blade arm 22 can be positioned and easily inserted into the mounting bracket 27, and the support pin 29 can be inserted to connect the two. Therefore, the assembly and disassembly work in the water can be performed easily and labor-saving without requiring a great effort to transport and install the large water purifier 1 assembled on land.
