[0021] The beneficial effects of the present invention are:

[0022] 1. The prior art usually uses an underwater walking mechanism or a surface walking mechanism to drive the dredging device to move as a whole. Due to the large resistance of water, it is difficult for the walking mechanism to move stably along a specific route. The present invention sets the walking mechanism on the second guide rail, and the dredging device can move along the second guide rail. The second guide rail plays a role in guiding and positioning, which can ensure that the dredging device moves more stably and the walking route is controllable.

[0023] 2. When the aquaculture pond of the present invention needs to be desilted, the walking mechanism moves intermittently along the second guide rail, driving the telescopic stand and the end plate to move horizontally. When one edge of the end plate contacts the bottom of the pond, the pond bottom, the end plate, the partition and the connecting plate form a closed desilting chamber. At this time, the desilting mechanism can be used to desilt the pond bottom within the coverage of the desilting chamber. Since the desilting chamber is isolated from the external space, desilting is carried out in a relatively closed space. Therefore, the silt in the desilting chamber will not spread to the external space, thereby preventing a large amount of silt from entering the water, ensuring the normal survival of aquatic products. After the pond bottom covered by a desilting chamber is desilted, the walking mechanism travels a certain distance, and at the same time, the driving mechanism drives the rotating shaft to rotate a specific angle, and the rotating shaft drives the end plate and the like to rotate as a whole at a specific angle, so that the next desilting chamber covers the next pond bottom, thereby achieving continuous desilting.

DETAILED DESCRIPTION

[0030] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0031] The aquaculture pond of the present invention is as follows Figures 1 to 5 As shown, the pond body 1 includes a rectangular breeding chamber, and first guide rails 2 are provided at both ends of the pond body 1, and the length direction of the first guide rail 2 is consistent with the width direction of the pond body 1; a moving frame 3 is provided on the first guide rail 2. The moving frame 3 can be matched with the first guide rail 2 through rollers, and in order to make the moving frame 3 move along the first guide rail 2, a motor and other equipment can be provided on the moving frame 3. In addition, the moving frame 3 can also be slidably matched with the first guide rail 2 through a slider, and the moving frame 3 is connected to a translational power mechanism that pushes the moving frame 3 to move along the first guide rail 2, and the translational power mechanism can adopt an existing conventional power mechanism such as a screw nut mechanism driven by a motor.

[0032] A pair of horizontal second guide rails 4 are arranged on the mobile frame 3, and the second guide rails 4 are perpendicular to the first guide rails 2, so that the length direction of the second guide rails 4 is consistent with the length direction of the pond body 1, and a dredging device is arranged on the second guide rails 4, and the dredging device includes a walking mechanism 5, and the walking mechanism 5 can move along the second guide rails 4. The first guide rails 2, the second guide rails 4 and the walking mechanism 5 are all above the water surface.

[0033] The walking mechanism of the traditional dredging device is set to sink into the pond bottom or float on the water surface. When walking, the water resistance is large, the fluctuation of the water body is easy to reach the walking stability, and it is easy to deviate from the set walking route. In the present invention, the dredging device is connected to the second guide rail 4, and the second guide rail 4 can play a role in positioning and guiding, ensuring that the dredging device can move stably along the set route, preventing its moving trajectory from deviating from the set route, and the walking mechanism 5 is set above the water surface, reducing the walking resistance.

[0034] A telescopic stand 6 is provided on the walking mechanism 5, and a horizontal rotating shaft 7 is provided at the bottom of the telescopic stand 6, and the rotating shaft 7 is rotatably mounted on the telescopic stand 6. The rotating shaft 7 is connected to a driving mechanism for driving the rotating shaft 7 to rotate; two end plates 8 in the form of regular polygons are fixedly provided on the rotating shaft 7, and the number of sides of the end plates 8 is ≥6. When the rotating shaft 7 rotates, the two end plates 8 are driven to rotate synchronously. The two end plates 8 are parallel to each other, and a plurality of partitions 9 are fixedly provided between the two end plates 8. Each partition 9 extends from the vertex of the end plate 8 toward the rotating shaft 7 along the radial direction of the rotating shaft 7, and the inner ends of any two adjacent partitions 9 are connected by a connecting plate 10, and the two adjacent partitions 9, the connecting plate 10 and the two end plates 8 form a silting chamber 11. The silting chamber 11 is connected to a silting mechanism.

[0035] The center of the end plate 8 coincides with the center of the rotating shaft 7. The present invention utilizes the partition plate 9 and the connecting plate 10 to enclose a plurality of dredging chambers 11 between the two end plates 8. When the rotating shaft 7 drives the end plate 8 to rotate, each dredging chamber 11 can work in turn. Specifically, during dredging, the bottom edge of the end plate 8 needs to contact the bottom of the pond. When one side of the end plate 8 is completely in contact with the bottom of the pond, the bottom dredging chamber 11 covers part of the bottom of the pond, and the bottom of the pond closes the port of the bottom dredging chamber 11, forming a relatively closed dredging chamber 11. At this time, the dredging mechanism is used to dredge the pond bottom covered by the dredging chamber 11. After the pond bottom covered by the bottom dredging chamber 11 is dredged, the walking mechanism 5 drives the dredging device as a whole to walk a certain distance. At the same time, the driving mechanism drives the rotating shaft to rotate a specific angle, and the rotating shaft drives the end plate and the like to rotate as a whole at a specific angle, so that the next dredging chamber 11 covers the next pond bottom, and then dredging is performed again, thereby achieving continuous dredging.

[0036] In the present invention, the end plate 8, the partition plate 9 and the connecting plate 10 are used to separate the silting chamber 11 from the external space, and the silting is carried out in the relatively sealed silting chamber 11. The silt inside the silting chamber is difficult to diffuse into the external water body, thereby avoiding a large amount of silt entering the water and causing turbidity of the water body, thereby ensuring the normal survival of aquatic products. When the present invention is silting, the normal operation of the aquaculture pond is not affected.

[0037] In order to improve the sealing performance between the edge of the end plate 8 and the pond bottom, the edge of the end plate 8 and the outer end of the partition 9 are covered with a sealing pad 12, which can be an elastic rubber pad or the like.

[0038] The desilting mechanism of the present invention includes a desilting pump 13 and a pressure pump 14 fixedly mounted on a telescopic stand 6. The desilting pump 13 is used to extract the sludge in the desilting chamber 11 to achieve desilting, while the pressure pump 14 is used to transport the aquaculture water in the aquaculture pond into the desilting chamber 11, and use the aquaculture water to flush the pond bottom covered by the desilting chamber 11, so that the sludge is separated from the pond bottom. In addition, the desilting chamber 11 and the pond bottom form a relatively closed space, and the aquaculture water from the outside is not easy to enter the desilting chamber 11. Therefore, the pressure pump 14 is used to replenish water in the desilting chamber, and the desilting pump 13 is used to extract the muddy water rich in sludge, so that the pressure balance inside and outside the desilting chamber 11 can be ensured.

[0039] Specifically, the rotating shaft 7 is a cylindrical hollow shaft, and the inner cavity of the hollow shaft is divided into a water inlet chamber 16 and a mud discharge chamber 17 by a ring plate 15, and the water inlet chamber 16 and the mud discharge chamber 17 are not connected. The water inlet chamber 16 is connected to a plurality of radially extending first connecting pipes 18, each of which is connected to a silting chamber 11, and the mud discharge chamber 17 is connected to a plurality of radially extending second connecting pipes 19, each of which is connected to a silting chamber 11, and each of the first connecting pipes 18 and the second connecting pipes 19 is provided with a valve 20; the silting pump 13 is connected to the mud discharge chamber 17 through a rotary joint, and the pressure pump 14 is connected to the water inlet chamber 16 through a rotary joint. One end of the first connecting pipe 18 and the second connecting pipe 19 are fixedly connected to the rotating shaft 7, and the other end is fixedly connected to the connecting plate 10, and the water inlet chamber 16 and the silting chamber 11 are connected, or the mud discharge chamber 17 and the silting chamber 11 are connected.

[0040] The inlet of the pressure pump 14 is connected to the water body in the pond body 1, and the aquaculture water in the pond body 1 can be transported to the water inlet chamber 16. The water in the water inlet chamber 16 enters the silting chamber 11 through the first connecting pipe 18, and then flushes the pond bottom covered by the silting chamber 11. The silting pump 13 sucks the mud-water mixture in the silting chamber 11 through the mud discharge chamber 17, and then transports it to the outside. When silting, the valve 20 on the first connecting pipe 18 and the second connecting pipe 19 connected to the bottom silting pump 13 is opened, and the valves 20 on the other first connecting pipes 18 and the second connecting pipes 19 are closed. The valve 20 can be a solenoid valve.

[0041] The desilting pump 13 can directly transport the sludge to the ground around the aquaculture pond. When the area of ​​the aquaculture pond is large, a longer pipeline is required to transport the sludge to the ground, and the discharged sludge contains a large amount of water, which is inconvenient to handle. Because the present invention sets a filtering mechanism 21 on the walking mechanism 5, and the desilting pump 13 is connected to the filtering mechanism 21 through a flexible mud discharge pipe 22. After the mixture of water and sludge enters the filtering mechanism 21, the sludge stays in the filtering mechanism 21, and the filtered water can be directly discharged into the breeding pond, which can prevent a large amount of water in the breeding pond from being lost, and is convenient for subsequent treatment of the sludge. The sludge in the filtering mechanism 21 can be cleaned at regular intervals.

[0042] The filtering mechanism 21 can adopt various existing water filtering equipment, but the filter materials used in conventional filtering equipment, such as sand and gravel particles or filter plates, are easy to clog and need to be cleaned or replaced frequently, which is troublesome to operate. The solid impurities cleaned out also need to be dehydrated by pressure filtration and other methods, which involves many processes and is inefficient.

[0043] The filter mechanism 21 of the present invention comprises a horizontally arranged cylinder 211, the cylinder 211 is a circular cylinder, a filter plate 212 is arranged inside the cylinder 211, filter holes are arranged on the filter plate 212, the edge of the filter plate 212 is slidably matched with the inner wall of the cylinder 211, and the filter plate 212 is connected to a pressure mechanism 215 for driving the filter plate 212 to slide, and the pressure mechanism 215 can be a hydraulic cylinder or other equipment. The two ports of the cylinder 11 are respectively provided with a detachable first end plate 213 and a second end plate 214, the distance from the filter plate 212 to the first end plate 213 is less than the distance from the filter plate 212 to the second end plate 214, a drainage cavity 216 is arranged between the filter plate 212 and the first end plate 213, and a water outlet is arranged at the bottom of the drainage cavity 216; a mud inlet cavity 217 is arranged between the filter plate 212 and the second end plate 214, and a mud inlet is arranged on the top wall of one end of the mud inlet cavity 217 close to the filter plate 212, and the mud inlet is connected to the mud discharge pipe 22. The pressure mechanism 215 may be installed on the first end plate 213 . The pressure mechanism 215 passes through the drainage cavity 216 and is detachably connected to the filter plate 212 .

[0044] During filtration, the mixture of sludge and water flows to the sludge inlet through the sludge discharge pipe 22, and then enters the sludge inlet chamber 217 through the sludge inlet. The sludge stays in the sludge inlet chamber 217, while the water enters the drainage chamber 216 through the filter plate 212 and is discharged from the water outlet at the bottom of the drainage chamber 216. When the sludge in the sludge inlet chamber 217 accumulates to a certain amount, the pressure mechanism 215 is used to push the filter plate 212 to move toward the second end plate 214 to squeeze the sludge. The water in the sludge enters the drainage chamber 216 through the filter plate 212 and then is discharged, and the sludge is gradually compressed. After the sludge is compressed, the second end plate 214 can be removed, and the pressure mechanism 215 pushes the filter plate 212 to continue to move, so that the compressed sludge can be discharged from the cylinder 211. At the same time, the filter plate 212 moves to the outside of the cylinder 211 to facilitate cleaning of the filter holes blocked in the cylinder 211.

[0045] In the present invention, the running mechanism 5 moves back and forth once along the second guide rail 4 to clean the sludge in the cylinder 211. During cleaning, the running mechanism 5 stops at the edge of the pond body 1 to facilitate transferring the sludge to the ground.

[0046] The water sprayed from the first connecting pipe 18 has a limited flushing area, and it is difficult to flush the entire pond bottom covered by the silt removal chamber 11, which may cause sludge to remain. In order to improve the sludge removal effect, the water outlet of the first connecting pipe 18 is connected to a rotating sleeve 23, and a blade 24 is arranged inside the rotating sleeve 23. The blade 24 is a hydraulic blade. The outer wall of the rotating sleeve 23 is provided with a stirring rod 25 perpendicular to the rotating sleeve 23, and a stirring blade 26 is arranged at the bottom of the stirring rod 25. The rotating sleeve 23 is sleeved outside the first connecting pipe 18 and rotates with the first connecting pipe 18. When water enters the rotating sleeve 23, the water flushes the blade 24, which can drive the blade 24 to rotate. When the blade 24 rotates, it drives the rotating sleeve 23, the stirring rod 25 and the stirring blade 26 to rotate, and the stirring blade 26 can scrape off the sludge on the pond bottom.

[0047] In the present invention, since the end plate 8 is not a circular plate, when the end plate 8 rotates with the rotating shaft 7, if the edge of the end plate 8 always contacts the bottom of the pond, then the center height of the end plate 8 changes. In order to adapt to this change, the end plate 8 is installed on the telescopic stand 6, and the telescopic stand 6 can be extended and retracted to adapt to the height change of the center of the end plate 8. Specifically, the telescopic stand 6 includes a mounting frame 61 and a lifting frame 62. The mounting frame 61 is fixedly installed on the walking mechanism 5, and the upper end of the lifting frame 62 is slidably matched with the mounting frame 61. A compression spring 63 is arranged between the middle part of the lifting frame 62 and the mounting frame 61. The compression spring 63 is always in a compressed state to ensure that the bottom edge of the end plate 8 is pressed against the bottom of the pond. When the end plate 8 rotates, the center height of the end plate 8 changes, which drives the lifting frame 62 to rise and fall, and the length of the compression spring 63 changes adaptively. Regardless of whether the center height of the end plate 8 moves upward or downward, the compression spring 63 can adapt to the height change of the lifting frame 62 by changing its length, while ensuring that the bottom edge of the end plate 8 presses the pond bottom, thereby ensuring the sealing between the dredging chamber 11 and the pond bottom.

[0048] The driving mechanism includes a reduction motor 64 installed on the lifting frame 62, and the reduction motor 64 is connected to the rotating shaft 7 through a chain. The reduction motor 64 is installed on the upper part of the lifting frame 62, above the water surface, to prevent the reduction motor 64 from entering the water. The reduction motor 64 can be raised and lowered synchronously with the lifting frame 62, without affecting the effective connection between the reduction motor 64 and the rotating shaft 7.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
