Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fish pond cleaning device for removing sediments from a fish pond which hatches or releases various fish such as salmon and trout.

[0002]

2. Description of the Related Art In a fish pond that hatches salmon or trout or releases them, natural water is used by taking in a part of water flowing into the river. However, because fish density is high in fishponds, the amount of food and dung increases. Such fish dung and the rest of the food settle at the bottom of the fishpond. In addition, dead fish and leaves are also deposited at the bottom of the fish pond. If these precipitates are left as they are, they will spoil and cause fungi to develop. As a result, the fish may become ill and pose a problem in terms of hygiene management of the fish pond.

[0003]

Conventionally, the following method has been used to remove such precipitates.

(1) A method using human power.

This is the most popular method, in which a person wearing long rubber pants enters a fish pond and a sediment is removed by using a broom or a brush. If you sweep it with a broom or brush, the sediment will wind up in the water and flow a little downstream and settle. This is a method of moving the precipitate in the downstream direction while repeating such work.

However, when hatching salmon, trout, etc., the breeding period of the fry is winter, and it is a heavy burden to work in cold water.

(2) A method using a broom or a brush having a width suitable for the fish pond.

As shown in FIG. 8, a cleaning tool 81 having a size corresponding to the width of the fish pond, such as a broom or a brush, is moved from the upstream side to the downstream side as indicated by arrow Y to remove the deposit. In the case of this method, the precipitate is rolled up like 82, and a sufficient cleaning effect cannot be obtained. Further, as in 83, the unswept residue appears, and in the case of a large amount of precipitate, it overflows as in 84.

It is also conceivable to move the broom slowly so that the sediment does not roll up. However, even if the movement speed of the broom is reduced, the sedimentation is inevitable. Moreover, the cleaning time becomes longer as the moving speed is reduced. In addition, the structure of the cleaning tool 81 becomes large and the cost becomes high. In addition, the fish may be trampled with a broom, or the fish may be surprised, which hinders its growth.

(3) A method of using a vacuum suction type cleaning device.

This is a method in which the suction port of the cleaning device is moved in the pond and the precipitate is sucked together with water. In this case, if the suction port is small, it will reciprocate in the pond many times in order to improve the cleaning effect. Also, if the suction port is enlarged, the fish will be sucked together. If you put a protective net on the suction port, you can prevent fish from being sucked in. However, the movement of the suction port surprises the fish and hinders the growth of the fish. In addition, the cost is high and the noise is high.

(4) A method using an electrically driven machine.

Since a motor, a pump, etc. are used underwater, it is necessary to make the device waterproof, which increases the cost. In addition, if there is a failure, there is a risk of electric leakage and death of the fish. (5) A method of ejecting seawater as a jet. Seawater is ejected as a jet to raise the sediment
This is a method of collecting the floating precipitate. This person
In the case of the law, a device that ejects seawater as a jet is moved.
In order to make it possible, for example, a facility such as a running rail is required.
However, the cost of the entire device increases. The present invention solves the above-mentioned drawbacks, and it is an object of the present invention to provide a low cost fish pond cleaning device that does not surprise or damage the fish and can reliably remove sediment. And

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG.

Pulleys 12A to 12D are arranged at four corners of a fish pond having a substantially rectangular shape shown by a dotted line 11. The arrow Y indicates the direction of water flow, and pulleys 12A, 12 are provided on the right bank.
B, and pulleys 12C and 12D are arranged on the left bank.
Then, a single rope 13 made of metal or synthetic fiber is stretched over these pulleys 12A to 12D.

Here, a structure in which one rope 13 is stretched between the pulleys 12A to 12D will be described with reference to FIG. One rope 13 is from pulley 12A to pulley 12B.
To the pulleys 12C and 12D. The rope wound around the pulley 12D, is formed in an endless (endless) back to pulley 12A in the opposite direction further. This
At that time, between pulleys 12A and 12B, pulleys 12B and 12C
And two ropes 1 between the pulleys 12C and 12D
3 is stretched. Further, of the two ropes between the pulley 12B and the pulley 12C, one rope is wound around the drive wheel 14. Therefore, when the drive wheel 14 rotates about the shaft 14a as shown by the arrow, the rope 13 is pulled and moved in one direction. The direction in which the rope 13 moves changes depending on the rotation direction of the drive wheel 14. Also,
The two ropes 13 stretched between the pulleys move in opposite directions.

Of the ropes stretched between the pulleys 12A and 12B and between the pulleys 12C and 12D, for example, the ropes 13 that move in the same direction are provided with fixing mechanisms 15a and 15b. Fixing mechanism 15a, 1
5b is used for fixing the support cord to the rope 13.

Now, the fixing mechanisms 15a and 15b will be described with reference to FIG.

In FIG. 3A, a part of the rope 13 is twisted 1
3a is provided, and the rope 13a is utilized by utilizing the twisted portion 13a.
3 is tied to the combiner 31 and the support string 32 is attached to the hook 31a. Further, in FIG. 3B, a fishing Tegs twist back 33 is used, and the rope 13 and the support cord 32 are connected by utilizing the loop portions on both sides. In addition, FIG.
Connects the two ropes 13a and 13b connecting the pulleys to the coupler 3
It is sandwiched from above and below by two plates 34a and 34b of No. 4, one rope 13b is fixed and the other rope 13a is freely movable. Further, the support cord 32 is tied to the hook 34c formed on the lower plate 34b.

By the way, the fixing mechanism 15 having the above structure
The support devices 16a and 16b are fixed to the support cord 32 attached to the a and 15b as shown in FIG. 1, and the jet pipe device 17 is attached between the support devices 16a and 16b.

Here, the jet pipe device 17 will be described with reference to FIG.

In FIG. 4, reference numeral 41 is a jet pipe, and a plurality of jet nozzle holes 42 are formed on the side surface at intervals in the extending direction of the jet pipe 41. Further, both ends of the jet pipe 41 are sealed with water blocking caps 43. Jet pipe 41
A hose 44 is connected to the center of the, and the hose 44 is connected to a pump 45. Further, the pump 45 has a water intake port 46.
It is connected to. Therefore, when the pump 45 operates, the water is sucked up from the water suction port 46, the water is supplied to the jet pipe 41, and is discharged from the jet nozzle hole 42. The pump 45 is installed above the water surface so that electricity does not leak into the water of the fish pond.

Further, the jet pipe device is provided with a roller (not shown), for example, at a portion in contact with the bottom of the fish pond so that the jet pipe device can easily move in the fish pond. Further, the supporting device for supporting the jet pipe device is also provided with a roller (not shown) at a position in contact with, for example, the shore of the fish pond.

As shown in FIG. 1, detectors 18a and 18b for detecting the position of the fixing mechanism 15b are arranged on the left bank of the fishpond, for example. Then, by utilizing the outputs of the detection devices 18a and 18b, a switch and a stopper are operated to control the direction and range in which the jet pipe device 17 moves.

With the above construction, the jet pipe device 17 is
For example, while moving from the upstream to the downstream of the fish pond, water is discharged from the jet nozzle hole 17a in the downstream direction as shown by the arrow f, and the sediment is moved and eliminated. At this time, for example, as shown in FIG. 5, the jet nozzle hole 51 is provided at a position obliquely below the jet pipe 52 so that the water discharged from the jet nozzle hole 51 is directed to the bottom of the fish pond so that the sediment does not move. I try to be effective. In addition, 53 is a jet flow discharged from the jet nozzle hole 51, 54 is a sediment moving by the jet flow, and 55 is a stagnant sediment. Also, 5
6 is the water surface and 57 is the bottom of the fishpond.

In the example of FIG. 5, the jet nozzle hole 51 is formed on one side of the jet pipe 52. However, the jet nozzle holes 51 may be formed on both the upstream side and the downstream side. With such a configuration, when the water flow in the fish pond is gentle, water can be discharged toward the upstream side to remove the sediment even when the jet pipe device moves from the downstream side to the upstream side.

Next, another embodiment of the present invention will be described with reference to FIG.
Will be described with reference to.

In the embodiment shown in FIG. 1, one jet pipe device extending in the width direction of the fish pond is moved along the flow. The upper part of FIG. 6 is an example in which the fishpond 60 is cleaned by, for example, three jet pipe devices 61, 61B, 61C. 61B is a jet pipe device for cleaning the central part,
1A and 61C are auxiliary jet pipe devices for cleaning both ends of the fish pond. The jet pipe device 61B and the auxiliary jet pipe devices 61A and 61C are arranged at a certain interval in the water flow direction. And the auxiliary jet pipe devices 61A, 61
In C, a roller 62a is provided at a portion contacting the side surface of the fish pond 60,
62c is attached. The auxiliary jet pipe device 6
1A and 61C have a structure that can freely move in the width direction of the fish pond 60. Therefore, it is effective when the width of the fishpond 60 is not uniform.

Further, in the lower portion of FIG. 6, a jet pipe device 63 is constituted by hinge pipes 64 at, for example, two places, and is bent at that portion. At this time, for example, springs (not shown) are used so that both ends of the jet pipe device 63 do not separate from the shore of the fish pond 60, and a force in the shore direction is applied as indicated by an arrow Y. Further, thin plate-shaped fins (not shown) may be attached to a portion of the jet pipe device 63, for example, on the shore side of the hinge pipe 64 in the upstream direction substantially parallel to the water surface. In this case, due to the resistance of the water when the jet pipe device 63 moves from the upstream to the downstream, the force of the discharged water, or the like,
A force toward the shore acts on both ends. At this time, if there is a fin in a part of the jet pipe device 63, the force acting on both ends of the jet pipe device 63 toward the bank works more effectively. Therefore, both ends will come into good contact with the shore even without a spring or the like.

[0034]

The jet pipe device used in the present invention may be made of a rigid pipe, but is made of, for example, a flexible material so that the jet pipe device is deformed according to the shape of the fish pond. It can be structured. At this time, the jet pipe device is deformed corresponding to the shapes of the corners and protrusions of the fish pond, and the cleaning effect can be enhanced.

Further, the jet pipe device is not installed at one place but is attached at a plurality of places at a certain interval in the direction of water flow, and these jet pipe devices are moved at the same time. The other jet pipe device may be configured to move from the downstream side to the upstream side. These configurations can be dealt with by providing many fixing devices for attaching the jet pipe device between the ropes connecting the pulleys.

Further, both end portions of one jet pipe device do not necessarily have to advance in the same direction, and one end may move from upstream to downstream and the other end may move from downstream to upstream. In this case, the jet pipe device makes a rotating motion, and the direction of the jet is also oblique. The precipitate pushed out by the jet stream is collected on the shore and can be easily collected.

As described above, according to the present invention, a commercially available pipe such as PVC can be used as the jet pipe device, and the cost can be reduced. Also, if the width of the fishpond is large, the pipes can be lengthened by splicing it, and if the width is narrow, it can be cut and shortened. it can. It is also possible to prepare a plurality of types of pipes having different shapes and intervals of nozzle holes, and exchange the pipes depending on the size and type of fish and the sediment. In addition, as the rope for moving the jet pipe device, large-sized fishing gussets that do not easily expand and contract and are strong against water can be used. Therefore,
Low cost and simple structure. Also, installation and removal,
Easy to maintain.

If the pump and the electric wire are installed so as not to be submerged in water, leakage can be prevented even if there is a failure. Also, there is little concern that the fish will be surprised or damaged. In addition, unmanned operation can be performed by combining it with a timer or controller.

Further, even when the protection net covering the fish pond is placed to protect the fish from birds, the precipitate can be cleaned and the work such as removing the protection net becomes unnecessary.

Further, since the precipitates can be removed in a short time, cleaning can be performed, for example, every time when feeding. Therefore, it is easy to control the amount of bait sprayed, which is effective in reducing breeding costs and promoting growth. In addition, since the work can be done without people entering the fishpond, it is possible to prevent the fish from showing their figures and improve the return rate of the released fry.
