Description

Technical Field

[0001] This utility model relates to the field of crayfish farming technology, and more specifically to a water-circulating crayfish farming device. Background Technology

[0002] Lobster farming equipment is used for raising lobsters. It is usually designed in a round or square shape to facilitate water circulation and sewage discharge. The pond is 1.0 to 1.2 meters deep, with a flat bottom that slopes slightly towards the drainage direction to ensure that the water can drain by gravity. The inlet and outlet are set up independently. The recirculating water lobster farming system purifies and recycles the farming wastewater, which significantly reduces water consumption and sewage discharge. During the transfer or temporary holding of lobsters, the lobster farming equipment and water circulation system prevent lobster mortality.

[0003] The shortcomings of existing technologies: The shape and depth of existing aquaculture equipment are not well designed. For example, the corners of square ponds are prone to accumulating dirt, which greatly reduces the utilization rate of space and restricts the activity space of crayfish. This can easily lead to fighting or disease transmission due to excessive density. At the same time, during the water circulation process of existing aquaculture equipment, impurities in the wastewater can easily cause blockage of the sewage pipes, affecting the wastewater treatment effect. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a water circulation crayfish farming device to solve the problems of unreasonable space design, limited space for crayfish activity, and easy blockage of pipes during sewage discharge in the existing crayfish farming devices mentioned in the background art.

[0005] This utility model provides the following technical solution: a water circulation type crayfish farming device, including a farming pond and a baffle plate fixedly connected to one side of its top. A water inlet pipe is fixedly connected to the middle of the top of the baffle plate. A water outlet is opened in the middle of the farming pond. A climbing structure is provided in the inner cavity of the farming pond. A water circulation channel is fixedly connected to one side of the outer surface of the farming pond. A dirt removal component is provided in the middle of the inner cavity of the water circulation channel.

[0006] The climbing structure includes a climbing board fixedly connected to the middle of the inner cavity of the aquaculture pond. Several anti-slip strips are fixedly connected to the surface of the climbing board, and an off-water platform is fixedly connected to one end of the climbing board.

[0007] Preferably, the climbing board is inclined towards the water outlet, one end of the climbing board is connected to the bottom of the inner cavity of the aquaculture pond, the other end of the climbing board is connected to the water-removal platform, and the shielding plate is located above the water-removal platform.

[0008] Preferably, a plurality of the anti-slip strips are arranged at equal intervals, and the anti-slip strips are composed of a plurality of arc-shaped blocks.

[0009] Preferably, the water circulation channel is connected to the water outlet, and a filtration device is fixedly connected to the end of the water circulation channel away from the water outlet.

[0010] Preferably, the impurity removal component includes a screen movably connected to the middle of the inner cavity of the water circulation channel, a drain outlet is provided on the water circulation channel, a sealing plate is rotatably connected to the inner cavity of the drain outlet, the screen and the sealing plate are arranged perpendicular to each other, a limit rod is rotatably connected to the top of the sealing plate, a locking block is fixedly connected to one side of the top of the water circulation channel, and the end of the limit rod away from the sealing plate is movably connected to the middle of the inner cavity of the locking block.

[0011] Preferably, the inlet pipe is equipped with a valve and a water pump, the input end of the inlet pipe is connected to the output end of the filtration device, and the output end of the inlet pipe is fixedly connected to a double-ended pipe.

[0012] Preferably, a piston is provided at the water outlet, and a hydraulic jack is fixedly installed at one end of the aquaculture pond near the water outlet, with the output end of the hydraulic jack being fixedly connected to one end of the piston.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model divides the inner cavity of the aquaculture pond into deep water, medium water, and shallow water zones by using an inclined climbing board. This allows crayfish to climb to the appropriate water depth as needed, effectively increasing the applicability of the crayfish farming environment. During the climbing process, anti-slip strips prevent crayfish from slipping, facilitating their climbing movement on the climbing board. At the same time, because the arc-shaped blocks that make up the anti-slip strips have through holes in the middle, crayfish feces or food residue and other impurities on the climbing board can be discharged through the through holes. As the inclined climbing board moves downward into the water, these impurities are discharged along with the wastewater, which helps to clean the inner cavity of the aquaculture pond.

[0015] 2. This utility model uses a simple impurity removal component to filter crayfish feces or food residues from wastewater. When the wastewater flows through the inner cavity of the water circulation channel, it passes through a screen inserted in the middle of the inner cavity, which filters out crayfish feces or food residues and other impurities. Larger impurities in the aquaculture water are simply filtered out. After filtration, the limiting rod is removed from the inner cavity of the locking block, and the sealing plate is pulled to rotate and open, allowing the impurities accumulated at the screen to be discharged through the drain outlet. The treated wastewater is purified by the filtration equipment and then reinjected into the inner cavity of the aquaculture pond through the inlet pipe, realizing the water circulation operation of the aquaculture device.

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The water circulation crayfish farming device involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] This utility model provides a water-circulating crayfish farming device, such as... Figure 1 - Figure 4 As shown, it includes a breeding pond 1 and a baffle plate 2 fixedly connected to one side of its top. A water inlet pipe 3 is fixedly connected to the middle of the top of the baffle plate 2. The breeding pond 1 is provided with a water outlet 4. A climbing structure 5 is provided in the inner cavity of the breeding pond 1. A water circulation channel 6 is fixedly connected to one side of the outer surface of the breeding pond 1. A dirt removal component 7 is provided in the middle of the inner cavity of the water circulation channel 6.

[0023] Furthermore, such as Figure 1 and Figure 2 As shown, the climbing structure 5 includes a climbing board 51 fixedly connected to the middle of the inner cavity of the breeding pond 1. Several anti-slip strips 52 are fixedly connected to the surface of the climbing board 51, and an off-water platform 53 is fixedly connected to one end of the climbing board 51.

[0024] Furthermore, such as Figure 2 and Figure 3As shown, the climbing board 51 is inclined towards the outlet 4. One end of the climbing board 51 is connected to the bottom of the inner cavity of the breeding pond 1, and the other end of the climbing board 51 is connected to the water-removing platform 53. The shield 2 is located above the water-removing platform 53. The inclined climbing board 51 divides the inner cavity of the breeding pond 1 into a deep water area, a medium water area, and a shallow water area. Since crayfish will adjust their activity position according to factors such as food distribution and water temperature changes, and do not stay fixed at the bottom of the water, crayfish can climb to a suitable water depth on the climbing board 51 as needed, and can hide under the shield 2.

[0025] Furthermore, such as Figure 2 and Figure 3 As shown, several anti-slip strips 52 are arranged at equal intervals. Each anti-slip strip 52 is composed of several arc-shaped blocks. The climbing board 51 is placed at an angle into the water in the breeding pond 1. When the crayfish climbs on the climbing board 51, the anti-slip strips 52 prevent the crayfish from slipping, which is conducive to the crayfish's climbing movement on the climbing board 51. At the same time, since there are through holes in the middle of the arc-shaped blocks that make up the anti-slip strips 52, the crayfish feces or food residue and other impurities on the climbing board 51 can be discharged through the through holes. As the inclined climbing board 51 moves downward into the water, it is discharged with the sewage, which is conducive to cleaning the inner cavity of the breeding pond 1.

[0026] Furthermore, such as Figure 1 and Figure 3 As shown, the water circulation channel 6 is connected to the outlet 4. The end of the water circulation channel 6 away from the outlet 4 is fixedly connected to the filter device 8. The sewage discharged from the inner cavity of the aquaculture pond 1 flows into the inner cavity of the water circulation channel 6 through the outlet 4, and then flows into the inner cavity of the filter device 8 for purification. The outlet 4 and the water circulation channel 6 are designed according to the shape of the aquaculture pond 1, which greatly reduces the blockage of the pipes during sewage discharge. The filter device 8 is based on the existing aerated biological filter. Its working principle is that the sewage comes into contact with the microbial film growing on the surface of the packing material in the inner cavity of the aerated biological filter, so that the sewage is purified.

[0027] Furthermore, such as Figure 1 and Figure 4As shown, the impurity removal component 7 includes a screen 71 movably connected to the middle of the inner cavity of the water circulation channel 6. A drain outlet 72 is provided on the water circulation channel 6. A sealing plate 73 is rotatably connected to the inner cavity of the drain outlet 72. The screen 71 and the sealing plate 73 are arranged perpendicular to each other. A limit rod 74 is rotatably connected to the top of the sealing plate 73. A locking block 75 is fixedly connected to one side of the top of the water circulation channel 6. The end of the limit rod 74 away from the sealing plate 73 is movably connected to the middle of the inner cavity of the locking block 75. After the water in the inner cavity of the aquaculture pond 1 flows out through the outlet 4, it flows through the water circulation channel 6. During the flow, it passes through the screen 71 inserted in the middle of its inner cavity. The screen 71 filters out impurities such as crayfish feces or food residue in the water, and performs simple filtration of larger impurities in the aquaculture water. After filtration, the limit rod 74 is removed from the inner cavity of the locking block 75, and the sealing plate 73 is pulled to rotate and open, so that the impurities accumulated at the screen 71 are discharged through the drain outlet 72.

[0028] Furthermore, such as Figure 1 and Figure 3 As shown, a valve 9 and a water pump 10 are installed on the inlet pipe 3. The input end of the inlet pipe 3 is connected to the output end of the filter device 8. A double-ended pipe 11 is fixedly connected to the output end of the inlet pipe 3. After the sewage is purified by the filter device 8, the valve 9 is opened so that the water pump 10 draws the purified water from the filter device 8 into the inlet pipe 3. The inlet pipe 3 is then reinjected into the inner cavity of the aquaculture pond 1 through the double-ended pipe 11, completing the water circulation operation of the aquaculture device.

[0029] Furthermore, such as Figure 2 and Figure 3 As shown, a piston 12 is installed at the outlet 4. A hydraulic jack 13 is fixedly installed at one end of the aquaculture tank 1 near the outlet 4. The output end of the hydraulic jack 13 is fixedly connected to one end of the piston 12. When sewage needs to be discharged, the hydraulic jack 13 is activated, and the piston 12 is driven to rise and fall through the hydraulic jack 13, so that the piston 12 controls the opening and closing of the outlet 4 to complete the discharge of sewage.

[0030] The working principle of this invention is as follows: First, the water in the inner cavity of the breeding pond 1 is added to a designated height. During crayfish farming, the inclined climbing board 51 divides the inner cavity of the breeding pond 1 into a deep water zone, a medium water zone, and a shallow water zone. Since crayfish adjust their activity position according to factors such as food distribution and water temperature changes, and do not stay fixed at the bottom, they can climb to a suitable water depth on the climbing board 51 as needed. They can also hide under the cover board 2. During the climbing process, the evenly distributed protective barriers on the surface of the climbing board 51 further enhance the protection against the crayfish's movement. The sliding strip 52 prevents crayfish from slipping. Crayfish feces or food scraps on the climbing board 51 can be discharged through the through-hole. As the inclined climbing board 51 moves downwards into the water, the wastewater is discharged, facilitating the cleaning of the inner cavity of the aquaculture pond 1. When the water pollution level in the inner cavity of the aquaculture pond 1 reaches a certain height, the hydraulic jack 13 is activated. The extension and retraction of the hydraulic jack 13's protruding end drives the piston 12 to move up and down. When the protruding end of the hydraulic jack 13 shortens, it drives the piston 12 to move upwards, thus cleaning the inner cavity of the aquaculture pond 1. Wastewater from the chamber is discharged through outlet 4 and enters the inner cavity of water circulation channel 6. It flows along the path of water circulation channel 6 towards the filtration device 8, passing through a screen 71 inserted in the middle of the inner cavity of water circulation channel 6. The screen 71 filters out impurities such as crayfish feces or food residue from the water, performing simple filtration of larger impurities in the aquaculture water. After filtration, the limiting rod 74 is removed from the inner cavity of the locking block 75, and the sealing plate 73 is pulled to rotate and open, allowing impurities accumulated at the screen 71 to be discharged through the drain outlet 72. The wastewater entering the inner cavity of the filtration device 8 comes into contact with the microbial film growing on the surface of the packing material in the inner cavity of the aerated biological filter, thus purifying the wastewater. After purification, the valve 9 is opened, so that the water pump 10 draws the purified water from the filtration device 8 into the inlet pipe 3. The inlet pipe 3 is then reinjected into the inner cavity of the aquaculture tank 1 through the double-ended pipe 11, completing the water circulation operation of the aquaculture device. After the water circulation is completed, the extended end of the hydraulic push rod 13 is extended, so that the piston 12 blocks the outlet 4, ensuring the airtightness of the inner cavity of the aquaculture tank 1.
