Description

  The present invention relates to a suspended matter collecting device, and in particular, purifies a closed water area or a microfluidic water area where suspended suspended matter is accumulated in a dam lake, pond, lake, reservoir, dam bay, moat or sea area. The present invention relates to a suspended substance collection device.

  In consideration of environmental problems, closed or microfluidic water areas where suspended suspended solids containing phytoplankton, etc. are retained in dam lakes, ponds, lakes, reservoirs, dam coves, moats or sea areas. Development of methods and devices for purification is active. This is because in addition to environmental problems, the problem of life and death of animals and plants inhabiting waters is also related.

  In order to efficiently collect suspended substances floating on the water surface or in the vicinity of the water surface, many patent documents forcibly generate a swirl or vortex and capture the suspended substance by the generated swirl or vortex. The suspension material is guided to the suspension material suction port, and the suspension material is sucked and collected by a water absorption pump or the like connected to the suspension material suction port.

  Patent Document 1 uses the above-described circulating or spiral water flow, and aims to provide a water purification device and a water purification method capable of recovering water surface suspended matters such as sea cucumbers in a wide range. The structure arrange | positions the suction inlet of a water absorption pipe | tube in the center part of the circulating flow generation means which consists of a rotary blade provided with the several wing | blade part in the circumference | surroundings. Then, with the rotation of the rotor blades, a water absorption action is performed from the suction port, and a spiral water flow centered on the suction port is generated in a water area having a wide diameter. As a result, the sea cucumber floating on the water area is sucked together with the water and collected. Here, the suction port is disposed below the surface of the water, and the rotary blade including a plurality of wings is configured to rotate around the suction port in water.

  That is, in the sampling method of Patent Document 1, a rotary blade is provided so as to surround a suction port of a water-absorbing pipe in water, and an annular water flow is generated around the suction port by the rotary blade, and a water-absorbing action is generated from the suction port. Is performed to generate a spiral water flow, and the water is placed on the spiral water flow and led to the suction port.

  According to this technique, the suspended matter or the like can be sucked and collected by generating a swirl or vortex, but a swirl generating means is required to generate the swirl or vortex. On the other hand, Patent Document 2 can be cited as an example of collecting floating suspended substances without generating a circulation.

  Patent document 2 makes it a subject to collect | recover and remove the surface layer sea bream of a growth period effectively using the characteristic of the sea float which floats on the water itself from the viewpoint of a sea bream recovery technique and accumulates in the lee by blowing air. In order to solve this problem, a floating ring is attached to the outer periphery, the draft is adjusted by the floating ring, and a double-pipe floating intake pipe with a small-diameter internal intake pipe is bowed to the surface of the closed water area on the leeward side. Connected in a shape. And, at the draft level, the internal intake pipe is inscribed in the inner periphery of the floating intake pipe, and a plurality of stagnation openings are formed at the inscribed draft level, and the surface water including the floating sea urchins from the stagnation openings provided at the draft level is The structure which provided the submersible pump drawn in in an intake pipe is disclosed.

  That is, the sampling method of Patent Document 2 forms a plurality of stagnation openings at the draft level in the lee of the sea bream-generating water area, and the surface water containing the mushrooms floating from the plurality of stagnation openings provided at the draft level in the internal intake pipe. It is to pull in.

JP 2000-303438 A JP 2005-46672 A

  In the purification method described in the above-mentioned Patent Document 1, since the water is put on the generated spiral water flow and led to the suction port, it is certainly possible to suck and collect suspended substances floating on the water surface or in the vicinity of the water surface. It is believed that there is. However, since the circulation generating means is required, the entire apparatus becomes large and complicated, and a dedicated work ship is required when moving by changing the work place. Therefore, it cannot be denied that the manufacturing cost of the suspended substance collection device is high and the operation cost is high.

  Furthermore, when the suspended substance is not effectively guided to the suction port, the suspended substance collected by suction is small, but the amount of absorbed water is large. It is important to effectively induce suspended solids to the suction port, but there is a limit to the method of suctioning and sampling by generating a circulatory or vortex flow, and the suspended solids to be collected absorb water. It cannot be denied that the amount of water increases to some extent.

  The recovery method described in Patent Document 2 draws surface water containing floating sea cucumbers from a plurality of stagnation openings provided at the draft level into the internal intake pipe, so that the suspended matter is effectively suspended on the water surface or in the vicinity of the water surface. Can be recovered. In addition, since no recirculation is used, no means for generating recirculation is required, and it is considered that the amount of water absorption per unit mass of the aspirated suspended matter may be small. However, in the method of Patent Document 2, it is necessary to connect the floating intake pipe having a double-pipe structure to the surface of the closed water area in the leeway in an arcuate manner, and thus the sampling device cannot be easily moved.

  In addition, since the suspended matter floating on the water surface is affected by the wind and flows downwind, it is desirable that the sampling device is not fixed at a fixed location but can be easily changed. Alternatively, it is desirable for the sampling device to follow the suspended matter that has flowed under the influence of the wind. As shown in Patent Document 2, when the suspended substance collection device is fixed at a certain location, it is difficult to collect the suspended substance when it is moved by the influence of the wind, and the recovery rate is reduced. .

  The present invention has been made in view of the above problems, and the object thereof is to enable efficient suction collection of suspended substances floating on the water surface or in the vicinity of the water surface with a simple structure, and to collect the collection device in a water area. It is an object of the present invention to provide a suspended substance collection device that does not need to be forcibly moved within.

  The suspended matter collection device according to claim 1 of the present invention has a suspended matter suction port supported so as to float in the vicinity of the water surface below the water surface by a floating support that can float on the water surface, In the suspended matter collecting apparatus for sucking and collecting suspended matter floating on the water surface from the suspended matter suction port, the suspended matter suction port has a plurality of upper opening grooves arranged radially with the suspended matter suction port substantially at the center. The groove portion is installed such that the edge of the upper opening is located near the water surface below the water surface, and the end on the suspension material suction port side is located near the suspension material suction port and the suspension material suction port. It is characterized by being provided on the floating support so as to be opposed to the surface.

  According to the above configuration, when water in the vicinity of the water surface is sucked from the suspended substance suction port and the flow of water to the suspended substance suction port is generated, the flow of water is also generated in the plurality of grooves. The plurality of grooves are arranged radially about the suspension material suction port, and the end on the suspension material suction port side is disposed near the suspension material suction port in the vicinity of the suspension material suction port. Effectively in a wide range, water containing suspended solids is guided to the suspended solid inlet and absorbed.

  According to a second aspect of the present invention, the floating support includes a reinforcing frame member formed in a frame shape forming a bottom portion, and a plurality of floating bodies fixed to the reinforcing frame member. Is provided with a flat plate upper member on the upper side of the reinforcing frame member, and the plurality of grooves are recessed downward from the upper surface of the flat plate upper member. Since the water to be sucked in is mainly limited to the water existing on the upper member of the flat plate, it is possible to generate the flow in the groove more effectively, and a wide range of water sucking including suspended solids. However, it is ensured more reliably. In addition, since the range of water sucked from the suspended substance suction port is limited, the load of the water absorption pump can be reduced.

  The upper member of the flat plate, the reinforcing frame member, and the floating body are configured to be able to rotate forward and backward with respect to the suspension material suction port, and a sail is attached to the floating body. Therefore, the upper member of the flat plate, the reinforcing frame member, and the floating body move while rotating according to the natural wind in the water area where the suspended substance is floating. Therefore, even when the suspended substance on the water surface is large and cannot be effectively sucked by one groove, the other adjacent groove can approach the suspended substance and suck it. Furthermore, since the suspended matter collecting device follows the suspended suspended matter in the water area that has been swept away by the wind, the suspended matter that has been swept away by the wind can be efficiently sucked and collected. Therefore, it is possible to save the labor and labor of forcibly moving the suspended substance collection device in the water area, and as a result, the operation cost can be greatly reduced.

  5. The suspension material suction port according to claim 4, wherein a canopy is installed in a hole penetrating the upper member of the flat plate in a circular shape above the suspension material suction port. Since a merged area is formed between the side end, the canopy, and the suspended substance suction port, water containing suspended substances induced by a plurality of grooves flows into the merged area all at once. Because it comes, it will be effectively inhaled from the suspension material inlet.

  As described in claim 5, since the floating support or the upper member is configured in a disk shape in plan view, and the radial lengths of the plurality of groove portions are the same, a wide range of the plurality of groove portions and Water containing suspended solids can be inhaled evenly, and it is convenient for rotational movement in the water area where suction sampling is performed.

  As described in claim 6, since the opening width of the groove portion becomes narrower toward the suspension material suction port, the flow of water generated in the groove portion increases the momentum toward the suspension material suction port. Accordingly, it is possible to efficiently guide and inhale the water containing the suspended matter to the suspended matter suction port.

  According to the suspended matter collection device of the present invention, the suspension material collecting device has a plurality of upper opening grooves arranged radially around the suspended matter suction port, so that it floats on or near the water surface with a simple configuration. The suspended substance to be collected can be effectively aspirated and collected in a wide range, and a clear water surface can be provided in the water area after the suspended substance collecting operation is performed.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a plan view of the suspended solid collection device of the present invention, and FIG. 2 is a schematic sectional view of the suspended solid collection device taken along the line AA in FIG. In the present embodiment, a description will be given on the assumption that the water is suspended or suspended in the vicinity of the water surface.

  The suspended matter collecting apparatus 10 includes a suspended matter suction port 12, a groove portion 14, a flat plate upper member 44, a reinforcing frame member 16, a floating body 18, a sail 22, a water absorption pump 24, and a water conduit 26. A floating support body 20 is formed by the reinforcing frame member 16 and the floating body 18, and the suspended substance suction port 12 is supported by the floating support body 20 so as to float near the water surface below the water surface. First, the overall configuration will be described. A circular frame 16a is formed in the central portion of the reinforcing frame member 16, and the suspended substance suction port 12 is disposed in a portion of the circular frame 16a. A suction pump 24 is installed. The floating support 20 is provided with a flat plate upper member 44 on the upper side of the reinforcing frame member 16 so as to be spaced apart from the upper surface of the flat plate upper member 44.

Eight floating bodies 18 are fixed to specific positions on the reinforcing frame member 16 outside the groove portion 14, and sails 22 are attached to the upper surface portion of the floating body 18 via pedestals 18 a. Hereinafter, each component will be described.

  The flat plate-shaped upper member 44 is made of a thin plate or a metal plate, and the groove portion 14 is fixed between the flat plate-shaped circular upper member 44 and the reinforcing frame member 16, thereby suspending the suspended substance. The collection device 10 realizes a solid configuration as a whole.

  The suspended substance suction port 12 is an inlet for sucking water containing suspended substances, and is provided so as to be connected to the main body of the water absorption pump 24, and an impeller 24b is provided therein. The water containing the suspended substance is sucked from the suspended substance suction port 12 and sent out through the water conduit 26. In the present embodiment, the suspension frame suction port 12 is provided in the reinforcing frame member 16 so as to be connected to the water absorption pump 24. However, only the suspension material suction port 12 is reinforced. The structure which the water absorption pump 24 attached to the frame member 16 and connected with this with a pipe, a hose, etc. may be installed in another place, for example, a shore side, may be sufficient.

  The radial grooves 14 extend substantially around the suspension material inlet 12, and the radial lengths of the grooves 14 are unified to the same length. As shown in FIG. The suspended substance suction port side end portion 14b of the sixteen grooves 14 is disposed opposite to the suspended substance suction port 12 in the vicinity of the suspended substance suction port 12. That is, the groove 14 is arranged such that the end portion 14b on the suspended substance suction port 12 side is spaced from the suspended substance suction port 12 at a constant interval. The groove portion 14 can be appropriately selected from plastic resin, polystyrene foam, wood, metal material, and the like, and a method of fixing the groove portion 14 between the flat plate upper member 44 and the reinforcing frame member 16 is as follows. Welding, screwing, tacking, adhesive, etc. can be selected as appropriate.

  The opening width of the groove portion 14 is gradually narrowed toward the suspended substance inlet side end portion 14b, and the edge portion 14a of each upper opening of the sixteen groove portions 14 is substantially the same by the flat plate upper member 44. It is adjusted by the reinforcing frame member 16 and the floating body 18, that is, the floating support body 20 so as to be at a height of about 2 to 3 cm below the water surface. The depth of the groove portion 14 is configured so that the inclination angle is changed in two steps and gradually becomes deeper toward the suspension material suction port side end portion 14b. That is, the depth becomes shallower at the first inclination angle θ1 from the suspension material inlet side end portion 14b to the outer side in the radial direction, and the gradient from the first inclination angle θ1 toward the outer side from the inclination angle changing portion 14c. Is configured such that the depth becomes shallower at the second inclination angle θ2 having a steep slope.

  A canopy 30 is installed at a position above the suspended substance suction port 12 in a hole penetrating the flat plate upper member 44 in a circular shape, and the suspended substance suction port side end 14b of the groove portion 14, the canopy 30, and the suspended substance. A junction area 28 is formed between the inlet 12 and the inlet 12. The canopy 30 is provided with a handle 30a, which is attached in a state that can be opened and closed. The canopy 30 is used for fixing the upper portion of the water absorption pump, and maintenance of the water absorption pump can be facilitated.

  A circular groove 32a is formed around the circular frame 16a of the reinforcing frame member 16, and a ball roller 32 is provided. The lower surface of the flange 34 provided on the upper part of the water absorption pump 24 from above is configured to come into contact with the ball roller 32 by its own weight. Since such a configuration is employed, even if the flat upper member 44, the reinforcing frame member 16, and the floating body 18 rotate, the water absorption pump 24 itself does not rotate.

  As described above, the floating body 18 is formed by the floating support body 20 including the reinforcing frame member 16 and the floating body 18, so that the edge portion 14 a of the upper opening of each groove portion 14, that is, the flat plate upper member 44 is 2 to 2 below the water surface. The number, material, etc. are selected so as to be 3 cm. In the present embodiment, as described above, the number of the floating bodies 18 is 8, and a rectangular body is used. However, a cube or a cylinder may be used regardless of this shape. Although the floating body 18 is firmly attached to the reinforcing frame member 16, an appropriate method such as screwing can be used for this fixing method.

  The sail 22 is attached to the upper part of the floating body 18 via a pedestal 18a. As the material of the sail 22, a plastic resin material, a cloth material, a plate material, or the like can be used as appropriate. Further, the sail 22 may be angled to receive wind efficiently.

  A dust screen 36 is attached to the outside of each floating body 18 to suspend the entry of floating matter such as long dust other than the sea cucumber and hangs below the surface of the water. In the present embodiment, a dustproof net 36 is provided so as to cover the outer sides of the eight floating bodies 18 and a weight 38 is attached to the lower end of the dustproof net 36 as necessary.

  FIG. 3 is an operation explanatory diagram in the water area of the suspended matter collecting apparatus 10 according to the present invention. Hereinafter, the operation of each part of the suspended matter collecting apparatus 10 of the present invention will be described in detail while explaining the work of sucking and collecting suspended substances floating on the water surface or in the vicinity of the water surface. First, the suspended substance collection device 10 is arranged at the first place where the suspended substance collection work in the water area is to be performed. Since the suspended matter collection device 10 can be moved freely by natural wind in the water area, the suspended matter collection device 10 is located anywhere in the water area unless the place to work first is specified. Also good. After the suspended matter collecting device 10 is disposed at a predetermined position, the water absorption pump 24 is operated.

  The water containing the suspended matter absorbed by the suspended matter collecting device 10 is sent to the water storage tank 40 installed on the shore in the water area through the water conduit 26. The water conduit 26 is made of a flexible material, and has a sufficient length so that the suspended solid collection device 10 can move within the water area sufficiently wide. Although not shown in the figure, the water storage tank 40 is provided with a treatment tank 42 installed on the shore through a second water storage tank (not shown) from which debris such as twigs are removed in the first water storage tank. Pumped and processed by a pump.

  The suspended matter collecting apparatus 10 installed at the first place where the suspended matter in the water area is to be sucked is operated by the suction pump 24, so that water is sucked from the suspended matter suction port 12. Is called. Then, a flow of water is generated in the 16 grooves 14. The opening width of the groove portion 14 is gradually narrowed toward the suspension material suction port 12, and the suspension material suction port side end portion 14 b of the groove portion 14 is connected to the merging region 28. The incoming water gathers all at once in the merging region 28 and is effectively absorbed from the suspension material inlet 12.

  Further, since the groove portion 14 is provided in the flat plate upper member 44 in a slit shape, the water sucked from the suspension material suction port 12 is limited to the water mainly existing on the flat plate upper member 44. Is done. As a result, the flow of water in the groove portion 14 is more effectively generated, and the wide-area inhalation of water containing suspended solids is more reliably ensured. In this way, in the area where the suspended substance collection device 10 is installed, the suspended substance is efficiently collected in a wide range, and a clear water surface is provided.

  On the other hand, suspended substances floating on the water surface or in the vicinity of the water surface are easily moved by the wind in the water area, so it was necessary to forcibly move the suspended substance collection device following the moved suspended substances. However, since the suspended solid collection device 10 of the present invention is provided with the ball roller 32 and the sail 22, it can be moved while rotating in the water area by wind. That is, the turbid substance collection device 10 of the present invention can collect the suspended substance moved by the wind by suction while naturally following it. Therefore, since the suspended solid collection device 10 rotates and moves freely in the water area, it is not necessary to forcibly or artificially pull, and the work cost can be greatly reduced.

  Since the suspended matter collecting apparatus 10 of the present invention is configured in a disk shape, it can suck water containing suspended matter from a plurality of grooves 14 in a wide range and evenly, and in the water area where suction collection work is performed. Convenient for rotational movement. The significance of the rotation of the suspended substance collection device 10 is that even if the suspended substance cannot be collected by aspiration in one groove part 14, the other adjacent groove part 14 approaches the suspended substance and aspirated and collected. It is in a point that can be done. Therefore, it is possible to suck and collect suspended substances in the water area more efficiently.

  In addition, since the suspended matter collecting device 10 is provided with a dustproof net 36, long-sized dust other than the sea cucumber does not enter the region where the groove portion 14 exists, and a good suspended matter sucking and collecting operation is performed. Is possible. In addition, when the weight 38 is attached to the lower end part of the dust net 36, the dust net 36 is stable even if the water area is waved by the weight 38.

  In addition, this invention is not limited to the said embodiment, A various change is possible in the range which does not deviate from the meaning of invention. For example, the number of groove portions 14 may be less than 16, and the cross-sectional shape thereof may be changed. Further, even if the number of sails 22 is changed, the shape and material thereof may be changed. Furthermore, the dimensions of each member are not limited to the embodiment, and the design can be changed as appropriate according to the water area from which the suspended substance is to be removed.

  INDUSTRIAL APPLICABILITY The present invention can be used in closed water areas or microfluidic water areas where suspended substances containing phytoplankton, etc. are retained in dam lakes, ponds, lakes, reservoirs, dam coves, moats or sea areas. . If various design changes are made without departing from the gist of the present invention, for example, oil recovery at the time of oil spill can be used to recover what is floating on the water surface.
