Description

Technical Field

[0001] This invention belongs to the field of aquaculture technology, specifically a rotary algae-removing brush for use in Litopenaeus vannamei ponds. Background Technology

[0002] In Litopenaeus vannamei (whiteleg shrimp) farming ponds, fixed or simple mobile algae removal devices are commonly used as the primary cleaning equipment. These devices typically consist of a brush body, a support frame, and a drive mechanism. The brush body is usually made of rigid fiber material and is driven by a motor or hydraulic system to rotate. Its main function is to remove algae and some sediment adhering to the pond walls to maintain the cleanliness of the aquaculture water. These devices have a relatively simple structure and are suitable for the routine maintenance of small to medium-sized aquaculture ponds.

[0003] During use, the operator first fixes the algae removal brush to a preset position on the edge or wall of the pool using the bracket, and adjusts the contact angle between the brush and the pool wall. After starting the drive mechanism, the brush rotates and scrubs along the surface of the pool wall, removing algae and dirt attached to the pool wall through physical friction.

[0004] Existing cleaning brushes use a motor to move the algae-removing brush along the inner wall of a circular aquaculture pond to achieve cleaning. However, when there are still shrimp in the pond, the brush can damage the shrimp, leading to losses in shrimp farming.

[0005] Therefore, the present invention provides a rotary algae removal brush for use in Litopenaeus vannamei farming ponds. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this invention to solve its technical problem is as follows: A rotary algae-removing brush for aquaculture ponds of Litopenaeus vannamei, comprising an aquaculture pond, an output motor, a swing arm, and a brush; an output motor that can drive the swing arm and brush to rotate is installed on the top of the aquaculture pond; the swing arm is fixedly connected to the output rod of the output motor; the brush contacts the inner wall of the aquaculture pond; an arc-shaped baffle is fixedly connected to the bottom of the swing arm; the side wall of the arc-shaped baffle is set close to the inner wall of the aquaculture pond; the arc-shaped baffle is located around the brush; wherein the swing arm, brush, and arc-shaped baffle rotate once inside the aquaculture pond and then reverse, realizing that the brush repeatedly cleans the inner wall of the aquaculture pond, which has a better effect than cleaning by moving in the opposite direction to one side; wherein the side wall of the arc-shaped baffle is close to the inner wall of the output motor, while leaving a gap, which can reduce the direct contact between the Litopenaeus vannamei and the brush.

[0008] By employing a bidirectional rotating cleaning mode, the efficiency of cleaning dirt adhering to the pool walls is improved. Meanwhile, the curved baffle arrangement reduces the possibility of direct contact between the Pacific white shrimp and the brush, helping to reduce the risk of injury to farmed shrimp during cleaning and improving the safety of the cleaning operation. The bidirectional rotating cleaning mode also reduces the difficulty of connecting the brush to other electrical wires, minimizing wire tangling.

[0009] Furthermore, a bracket is fixedly connected to the top of the arc-shaped baffle; a water suction pipe is fixedly connected to the middle of the bracket; one end of the water suction pipe extends between the arc-shaped baffle and the brush, and the other end is located at the top of the arc-shaped baffle; the end of the water suction pipe located at the top of the arc-shaped baffle is connected to a filter chamber, wherein a filter element that can be installed and removed is installed inside the filter chamber; a water pump is connected to the bottom of the filter chamber; wherein the water pump can extract the liquid inside the filter chamber to achieve a negative pressure state inside the filter chamber, and the end of the water suction pipe located between the arc-shaped baffle and the brush can deliver water to the inside of the filter chamber.

[0010] By integrating suction filtration, water purification can be achieved simultaneously during the scrubbing process, reducing secondary pollution of aquaculture water by scrubbed dirt. At the same time, the detachable filter structure provides convenience for maintenance and cleaning, which is conducive to maintaining the long-term stable operation of the system.

[0011] Furthermore, the water pump output end is connected to a water delivery pipe; the middle of the water delivery pipe extends to the side wall near the arc-shaped baffle; multiple water spray holes are opened on the water delivery pipe; the water spray holes on the water delivery pipe are set towards the side wall of the arc-shaped baffle; the water spray holes can impact the water delivered by the water pump onto the inner side wall of the aquaculture pond, reducing the possibility of shrimp entering the interior of the arc-shaped baffle when the arc-shaped baffle moves.

[0012] By using water pumps to spray water, not only is water recycling achieved and additional power requirements reduced, but the water flow disturbance generated by the spray holes can form a gentle barrier water curtain for shrimp as the arc-shaped baffle moves. Taking advantage of the shrimp's natural tendency to avoid disturbances, they will actively avoid the cleaning area, thereby reducing the possibility of shrimp entering the arc-shaped baffle. At the same time, the auxiliary water flow impact also helps to pre-wet or rinse the pool walls, thus working in synergy with the brush to improve the overall cleaning efficiency.

[0013] Furthermore, the sidewall of the arc-shaped baffle is rotatably connected to multiple rollers; the rollers are in contact with the inner wall of the aquaculture pond.

[0014] The rolling support of the rollers reduces the frictional resistance between the curved baffle and the pool wall, which helps the equipment to operate smoothly. At the same time, the rollers also help maintain the stability of the gap between the curved baffle and the pool wall.

[0015] Furthermore, the middle part of the water pump pipe is provided with multiple through holes.

[0016] The porous suction structure increases the water treatment capacity per unit time, improves the extraction efficiency of suspended solids, and reduces the possibility of clogging of the suction pipe.

[0017] Furthermore, a support plate is fixedly connected to the middle of the water supply pipe; a folded elastic cloth is fixedly connected to the bottom of the support plate, wherein the folded elastic cloth is sleeved on the water supply pipe; a float is fixedly connected to the bottom of the folded elastic cloth; wherein the float can adjust the length of the folded elastic cloth according to the liquid level inside the aquaculture pond, and the folded elastic cloth can block the water spraying from the spray holes it covers.

[0018] By linking the float and the folded elastic cloth, the effective spray area of ​​the spray hole is adaptively adjusted, enabling it to optimize the water jet range according to changes in liquid level and improve the system's adaptability to different water levels.

[0019] Furthermore, a counterweight ring is fixedly connected to the bottom of the float.

[0020] By setting a counterweight ring, the stability of the float is improved when the liquid level fluctuates, enabling it to respond more accurately to changes in liquid level, thereby optimizing the covering and adjustment effect of the folded elastic cloth on the spray nozzles.

[0021] Furthermore, a limiting plate is fixedly connected to the bottom end of the water delivery pipe; the diameter of the limiting plate is larger than the diameter of the counterweight ring; the limiting plate is made of a flexible material.

[0022] The flexible limiting plate reduces the possibility of the float and counterweight ring accidentally falling off the water supply pipe. At the same time, the flexible material also reduces the risk of damage caused by hard collisions with the pool bottom or other structures.

[0027] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0028] like Figures 1 to 3 As shown in the embodiment of the present invention, a rotary algae-removing brush for a Litopenaeus vannamei (whiteleg shrimp) aquaculture pond includes an aquaculture pond 1, an output motor 11, a swing arm 12, and a brush 13. The output motor 11, capable of driving the swing arm 12 and brush 13 to rotate, is installed on the top of the aquaculture pond 1. The swing arm 12 is fixedly connected to the output rod of the output motor 11. The brush 13 contacts the inner wall of the aquaculture pond 1. An arc-shaped baffle 14 is fixedly connected to the bottom of the swing arm 12. The sidewall of the arc-shaped baffle 14 is positioned close to the inner wall of the aquaculture pond 1. The arc-shaped baffle 14 is located around the brush 13. The swing arm 12, brush 13, and arc-shaped baffle 14 rotate once inside the aquaculture pond 1 and then reverse direction, enabling the brush 13 to repeatedly clean the inner wall of the aquaculture pond 1, which is more effective than cleaning by moving in opposite directions to one side. The sidewall of the arc-shaped baffle 14 is close to the inner wall of the output motor 11, while leaving a gap, which reduces direct contact between the Litopenaeus vannamei (whiteleg shrimp) and the brush 13.

[0029] The output motor 11 drives the swing arm 12, which is fixed to its output rod, to rotate in both directions. This causes the brush 13, fixed to the bottom of the swing arm 12, to repeatedly scrub the inner wall of the aquaculture pond 1. Simultaneously, an arc-shaped baffle 14 is positioned around the brush 13 with its sidewall close to the inner wall of the aquaculture pond 1, leaving a gap between the baffle 14 and the pond wall. This allows the baffle 14 to partially block the working area of ​​the brush 13 during the scrubbing operation. The bidirectional rotation cleaning mode improves the cleaning efficiency of dirt adhering to the pond wall. Furthermore, the arrangement of the arc-shaped baffle 14 reduces the possibility of direct contact between the shrimp and the brush 13, helping to reduce the risk of injury to the shrimp during cleaning and improving the safety of the cleaning operation. The bidirectional rotation cleaning mode also reduces the difficulty of connecting the brush 13 to other electrical wires, minimizing wire tangling.

[0030] like Figure 4As shown, a bracket 2 is fixedly connected to the top of the arc-shaped baffle 14; a water suction pipe 21 is fixedly connected to the middle of the bracket 2; one end of the water suction pipe 21 extends between the arc-shaped baffle 14 and the brush 13, and the other end is located at the top of the arc-shaped baffle 14; the end of the water suction pipe 21 located at the top of the arc-shaped baffle 14 is connected to a filter chamber 22, wherein a filter element that can be installed and removed is installed inside the filter chamber 22; a water pump 23 is connected to the bottom of the filter chamber 22; wherein the water pump 23 can extract the liquid inside the filter chamber 22 to achieve a negative pressure state inside the filter chamber 22, and the end of the water suction pipe 21 located between the arc-shaped baffle 14 and the brush 13 can deliver water to the inside of the filter chamber 22.

[0031] By setting up a bracket 2 fixed to the top of the arc-shaped baffle 14 and a water pump 21 fixed to its middle, one end of the water pump 21 extends between the arc-shaped baffle 14 and the brush 13, and the other end connects to the filter chamber 22. In conjunction with the water pump 23 connected to the bottom of the filter chamber 22, liquid is drawn to form a negative pressure inside the filter chamber 22. This allows suspended matter generated during the brushing process to be drawn into the filter chamber 22 along with the water flow through the water pump 21 and filtered through the removable filter element inside. By integrating the suction and filtration function, water purification can be achieved simultaneously during the brushing process, reducing secondary pollution of the aquaculture water by the brushed dirt. At the same time, the removable filter element structure provides convenience for maintenance and cleaning, which is conducive to maintaining the long-term stable operation of the system.

[0032] like Figure 4 As shown, the output end of the water pump 23 is connected to a water delivery pipe 3; the middle of the water delivery pipe 3 extends to the side wall near the arc-shaped baffle 14; multiple water spray holes 31 are provided on the water delivery pipe 3; the water spray holes 31 are arranged on the water delivery pipe 3 facing the side wall of the arc-shaped baffle 14; the water spray holes 31 can impact the water delivered by the water pump 23 onto the inner side wall of the aquaculture pond 1, reducing the possibility of shrimp entering the interior of the arc-shaped baffle 14 when the arc-shaped baffle 14 moves.

[0033] By setting up a water supply pipe 3 connected to the output end of the water pump 23, the water flow pumped out by the water pump 23 after being treated by the filter chamber 22 is guided and utilized, and the water supply pipe 3 is extended to the side wall near the arc-shaped baffle 14. At the same time, multiple water spray holes 31 are opened on the water supply pipe 3 facing the side wall of the arc-shaped baffle 14. Through this setting, the water flow of the water pump 23 can be effectively utilized, and a directional water flow is formed by spraying water through the water spray holes 31 to a specific area of ​​the inner side wall of the aquaculture pond 1. By using the water output of the water pump 23 for spraying, not only is the recycling of water resources realized and the additional power demand reduced, but the water flow disturbance generated by the water spray holes 31 can form a gentle barrier water curtain for shrimp during the movement of the arc-shaped baffle 14. Taking advantage of the shrimp's natural tendency to avoid disturbance, they will actively avoid the cleaning area, thereby reducing the possibility of shrimp entering the interior of the arc-shaped baffle 14. At the same time, the auxiliary water flow impact is also conducive to pre-wetting or rinsing the pond wall, thus working in synergy with the brush 13 to improve the overall cleaning efficiency.

[0034] like Figure 2 As shown, the side wall of the arc-shaped baffle 14 is rotatably connected to multiple rollers 4; the rollers 4 are in contact with the inner wall of the aquaculture pond 1.

[0035] By setting multiple rollers 4 rotatably connected to the side wall of the arc-shaped baffle 14 and keeping the rollers 4 in contact with the inner wall of the aquaculture pond 1, the arc-shaped baffle 14 can roll along the pond wall through the rollers 4 during the rotation of the swing arm 12. The rolling support of the rollers 4 reduces the frictional resistance between the arc-shaped baffle 14 and the pond wall, which helps the equipment to operate smoothly. At the same time, the rollers 4 also help maintain the stability of the gap between the arc-shaped baffle 14 and the pond wall.

[0036] like Figure 4 As shown, the middle part of the water pumping pipe 21 is also provided with multiple through holes 5.

[0037] By setting multiple through holes 5 in the middle of the water pumping pipe 21, the water pumping pipe 21 can not only draw water from the end during the negative pressure suction process, but also expand the water suction range from the side through the through holes 5. The multi-hole suction structure increases the water treatment capacity per unit time, improves the efficiency of suspended debris extraction, and reduces the possibility of blockage of the water pumping pipe 21.

[0038] like Figure 6 As shown, a support plate 6 is fixedly connected to the middle of the water supply pipe 3; a folded elastic cloth 61 is fixedly connected to the bottom of the support plate 6, wherein the folded elastic cloth 61 is sleeved on the water supply pipe 3; a float 62 is fixedly connected to the bottom of the folded elastic cloth 61; wherein the float 62 can adjust the length of the folded elastic cloth 61 according to the liquid height inside the aquaculture pond 1, and the folded elastic cloth 61 can block the water spraying from the spray hole 31 it covers.

[0039] By setting a support plate 6 fixed to the middle of the water supply pipe 3 and a folded elastic cloth 61 fixed to the bottom of the water supply pipe 3, and fixing a float 62 to the bottom of the folded elastic cloth 61, the float 62 moves and sinks with the changes in the liquid level in the aquaculture pond 1, causing the folded elastic cloth 61 to expand and contract, thereby automatically adjusting the area covered by the water spray hole 31 on the water supply pipe 3; through the linkage of the float 62 and the folded elastic cloth 61, the effective spray area of ​​the water spray hole 31 is adaptively adjusted, so that it can optimize the water flow spray range according to the changes in liquid level, and improve the system's adaptability to different water levels.

[0040] like Figure 6 As shown, a counterweight ring 7 is fixedly connected to the bottom of the float 62.

[0041] By fixing a counterweight ring 7 to the bottom of the float 62, an additional sinking counterweight is provided for the float 62; the setting of the counterweight ring 7 improves the stability of the float 62 when the liquid level fluctuates, enabling it to respond more accurately to changes in liquid level, thereby optimizing the covering and adjustment effect of the folded elastic cloth 61 on the spray hole 31.

[0042] like Figure 6 As shown, a limiting plate 8 is fixedly connected to the bottom end of the water supply pipe 3; the diameter of the limiting plate 8 is larger than the diameter of the counterweight ring 7; the limiting plate 8 is made of flexible material.

[0043] By setting a limiting plate 8, which is made of flexible material and has a diameter larger than that of the counterweight ring 7, at the bottom of the water supply pipe 3, the movement of the float 62 and the counterweight ring 7 is physically limited. The limiting effect of the flexible limiting plate 8 reduces the possibility of the float 62 and the counterweight ring 7 accidentally falling off the water supply pipe 3. At the same time, the flexible material also reduces the risk of damage caused by hard collision with the bottom of the pool or other structures.

[0044] During operation, the output motor 11 drives the swing arm 12, which is fixed to its output rod, to rotate in both directions. This causes the brush 13, which is fixed to the bottom of the swing arm 12, to repeatedly scrub the inner wall of the aquaculture tank 1. Simultaneously, an arc-shaped baffle 14 is installed around the brush 13 with its sidewall close to the inner wall of the aquaculture tank 1, leaving a gap between the baffle 14 and the tank wall. This allows the arc-shaped baffle 14 to partially block the working area of ​​the brush 13 during the scrubbing operation. A bracket 2 is fixed to the top of the arc-shaped baffle 14, and a water pipe 21 is fixed to its middle. One end of the water suction pipe 21 extends between the arc-shaped baffle 14 and the brush 13, and the other end connects to the filter chamber 22. A water pump 23, connected to the bottom of the filter chamber 22, draws liquid to create a negative pressure inside the filter chamber 22. This allows suspended solids generated during the washing process to be drawn into the filter chamber 22 along with the water flow through the water suction pipe 21 and filtered by the removable filter element inside. A water delivery pipe 3, connected to the output end of the water pump 23, guides the water flow pumped out by the water pump 23 after being processed by the filter chamber 22, and extends the water delivery pipe 3 to the side near the arc-shaped baffle 14. At the wall, multiple spray holes 31 facing the side wall of the arc-shaped baffle 14 are opened on the water supply pipe 3; multiple rollers 4 are rotatably connected to the side wall of the arc-shaped baffle 14, and the rollers 4 are kept in contact with the inner wall of the aquaculture pond 1, so that the arc-shaped baffle 14 can roll along the pond wall through the rollers 4 during the rotation of the swing arm 12; multiple through holes 5 are opened in the middle of the water suction pipe 21, so that the water suction pipe 21 can not only suck water from the end during the negative pressure suction process, but also expand the water suction range from the side through the through holes 5; a support plate 6 fixed to the middle of the water supply pipe 3 is provided. A folded elastic cloth 61, which is fixed to the bottom of the water supply pipe 3, is sleeved on it. A float 62 is fixed to the bottom of the folded elastic cloth 61. The float 62 moves with the change of the liquid level in the aquaculture tank 1, causing the folded elastic cloth 61 to expand and contract, thereby automatically adjusting the area it covers on the water spray hole 31 of the water supply pipe 3. A counterweight ring 7 is fixed to the bottom of the float 62, providing additional sinking counterweight for the float 62. A limiting plate 8, which is made of flexible material and has a diameter larger than the counterweight ring 7, is fixed to the bottom of the water supply pipe 3, providing physical limitation for the movement of the float 62 and the counterweight ring 7.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
