Abstract
Description
Technical Field
[0001] This utility model relates to the field of aquaculture technology, specifically an aquaculture drainage device. Background Technology
[0002] Aquaculture ponds are places where aquatic economic plants and animals are raised. Aquatic economic plants and animals are then sold to generate income. Aquaculture ponds need to have their water changed regularly to ensure that the water quality is suitable for the survival of aquatic economic plants and animals. Pumps and other drainage devices are usually used to discharge the water from the aquaculture ponds.
[0003] The publication number "CN217364301U" discloses a drainage device for an aquaculture pond. This device has a drainage mechanism installed inside the pond. A motor drives the drainage propeller to rotate, allowing water, feces, and food in the pond to be discharged through the drain outlet. It is not only highly efficient in drainage but also prevents blockages. The device is equipped with an adjustment mechanism and a cleaning device. The motor drives the threaded rod to rotate, causing the cleaning device to move inside the pond. The motor drives the cleaning brush to rotate, allowing the cleaning brush to clean the feces at the bottom of the pond, making it easy to clean the pond.
[0004] However, the above-mentioned device still has the following problems during implementation:
[0005] When water pumps discharge water from aquaculture ponds that is not suitable for the survival of aquatic economic plants and animals, they often lack protective functions during the water intake process, allowing debris to easily enter the pump. This can severely affect the pump's operation. Furthermore, they do not have the function of cleaning aquatic plants during the pumping process, which can lead to aquatic plants and debris clogging the inlet, preventing the pump from pumping water at a high flow rate and affecting the efficiency of drainage from the aquaculture pond.
[0006] Chinese patent discloses a drainage device for aquaculture ponds (authorization announcement number CN220384019U). This patented technology involves immersing a filter box inside the aquaculture pond, then starting a water pump. Wastewater passes through a protective mechanism before entering the pump, preventing debris from entering. Simultaneously, when debris accumulates on the filter screen, a cleaning mechanism removes it and collects it. This solves the problem that water pumps typically lack a protective function during water intake, allowing debris to easily enter and potentially affect pump operation. Furthermore, the lack of a function to clean aquatic plants during pumping can cause them and debris to clog the inlet, preventing the pump from pumping at high flow rates and impacting the efficiency of aquaculture pond drainage.
[0007] However, it has certain drawbacks: its cleaning mechanism can only remove loose debris attached to the surface of the filter screen. It cannot effectively deal with small, hard debris such as gravel and sand stuck in the filter screen mesh. Such small debris will stubbornly get stuck inside the mesh, and the flat cleaning action of the brush is difficult to shake it off or remove it. With long-term operation, the mesh blockage will continue to accumulate and gradually form deep blockage, causing the filter screen to lose permeability irreversibly, thereby reducing the water pump's pumping efficiency. Utility Model Content
[0008] The purpose of this utility model is to provide an aquaculture drainage device to solve the problems mentioned in the background art.
[0009] To achieve the above objectives, this utility model provides the following technical solution:
[0010] A drainage device for aquaculture includes a water pump, with a water pipe fixedly connected to the water inlet end of the water pump, and a filter box connected to the inside of the water pipe fixedly connected to the end of the water pipe away from the water pump. A filter plate is fixedly connected through the lower surface of the filter box, and a cleaning mechanism is provided on the left side surface of the filter box.
[0011] The filter box has two horizontal plates symmetrically fixed inside. The upper surface of the horizontal plates is provided with an anti-clogging mechanism, which includes a vertical plate. A motor is fixed to the rear surface of the vertical plate, and a cam is fixed to the output end of the motor. An anti-clogging component is provided on the front surface of the vertical plate below the cam.
[0012] As a further embodiment of this utility model: the cleaning mechanism includes an L-shaped plate, a telescopic cylinder is fixedly connected to the left side surface of the L-shaped plate, and a brush plate is fixedly connected to the telescopic end of the telescopic cylinder.
[0013] As a further embodiment of this utility model: the anti-blocking component includes a slider one, an anti-blocking rod is movably connected through the inside of the slider one, a slider two is fixedly sleeved above the slider one on the outside of the anti-blocking rod, a spring is fixedly connected to the lower surface of the slider two outside the anti-blocking rod, and an elastic block is fixedly connected to the lower end of the anti-blocking rod.
[0014] As a further embodiment of this utility model: the lower surfaces of the filter box and the filter plate are flush, and the lower end of the vertical plate is fixed to the upper surface of the horizontal plate.
[0015] As a further embodiment of this utility model: the upper end of the L-shaped plate is fixed to the left side surface of the filter box, and the upper surface of the brush plate is movably attached to the lower surface of the filter box and the filter plate.
[0016] As a further embodiment of this utility model: the rear end of the first slider is fixed to the front surface of the vertical plate, the upper end of the anti-blocking rod is movably attached to the cam, and the lower end of the anti-blocking rod is directly opposite the filter plate. The anti-blocking rod movably passes through the horizontal plate. The rear end of the second slider is slidably connected to the front surface of the vertical plate, and the lower end of the spring is fixed to the first slider.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] 1. This utility model uses the telescopic cylinder of the cleaning mechanism to drive the brush plate to move back and forth, and uses its bristles to continuously clean the lower surface of the filter plate. This can effectively remove debris such as gravel and water plants accumulated on the surface of the filter plate, prevent surface clogging, significantly improve the permeability of the filter plate, and thus ensure a stable drainage speed and drainage efficiency.
[0019] 2. This utility model uses a motor-driven cam to rotate the anti-clogging mechanism, which in turn drives the anti-clogging rod to overcome the spring resistance and perform periodic lifting and lowering movements. This causes the elastic block at the lower end to repeatedly strike the upper surface of the filter plate, generating a vibration effect. This vibration can effectively loosen and shake off small debris (such as pebbles) stuck inside the filter plate's filter holes, solving the problem of deep clogging and further ensuring the long-term filtration efficiency and smooth water flow of the filter plate.

[0026] A base is installed on the lower surface of the filter box 3 on the outside of the filter plate 4 to support the filter box 3;
[0027] The filter box 3 is placed in the aquaculture pond. Water enters the filter box 3 through the filter plate 4 and is then sucked away through the water pipe 2.
[0028] The filter plate 4 is used to prevent debris (pebbles, aquatic plants, etc.) in the water from entering the water pump 1 through the water pipe 2 and causing damage to the water pump 1;
[0029] The telescopic cylinder 7 is preferably a pneumatic cylinder, which is used to drive the brush plate 8 to clean the filter plate 4, so as to avoid the accumulation of debris and blockage of the filter plate 4, thereby affecting the drainage speed.
[0030] The brush plate 8 includes a plate body and brush bristles fixed to the upper surface of the plate body. The brush bristles are attached to the filter plate 4. The length of the brush plate 8 is sufficient to cover the entire lower surface of the filter plate 4 during its left and right movement.
[0031] exist Figure 1 , Figure 2 and Figure 4 In the filter box 3, two horizontal plates 9 are symmetrically fixed inside. An anti-clogging mechanism 10 is provided on the upper surface of each horizontal plate 9. The anti-clogging mechanism 10 includes a vertical plate 11, the lower end of which is fixed to the upper surface of the horizontal plate 9. A motor 12 is fixed to the rear surface of the vertical plate 11, and a cam 13 is fixed to the output end of the motor 12. An anti-clogging component 14 is provided on the front surface of the vertical plate 11 below the cam 13. The anti-clogging component 14 includes a slider 15, the rear end of which is fixed to the front surface of the vertical plate 11. The slider 15 is internally movable. An anti-blocking rod 16 is connected through the filter plate 9. The upper end of the anti-blocking rod 16 is movably attached to the cam 13, and the lower end of the anti-blocking rod 16 is directly opposite the filter plate 4. The anti-blocking rod 16 movably passes through the horizontal plate 9. The outer side of the anti-blocking rod 16 is fixedly sleeved above the slider 15. The rear end of the slider 17 is slidably connected to the front surface of the vertical plate 11. The lower surface of the slider 17 is fixedly connected to the outside of the anti-blocking rod 16. The lower end of the spring 18 is fixedly connected to the slider 15. The lower end of the anti-blocking rod 16 is fixedly connected to the elastic block 19.
[0032] A sealing cover can be installed on the rear surface of the vertical plate 11 outside the motor 12; a dynamic seal is installed between the output shaft of the motor 12 and the vertical plate 11; the sealing cover is a housing with a flange edge, which is used to fix it to the vertical plate 11. The edge (flange) of the sealing cover is fastened to the rear surface of the vertical plate 11 by multiple bolts or screws. A sealing gasket or sealant (such as silicone, rubber O-ring or flat gasket) is provided between the contact surface of the flange and the vertical plate 11 to ensure absolute sealing at the joint; the dynamic seal includes a stationary ring and a dynamic ring. The stationary ring is fixed in the vertical plate 11, and the dynamic ring is fixed outside the output shaft of the motor 12;
[0033] Motor 12 is preferably a variable frequency motor, which can be adjusted to the required speed;
[0034] When the cam 13 rotates, it can drive the anti-clogging rod 16 to move up and down repeatedly, striking the filter plate 4 at an appropriate frequency, causing the filter plate 4 to vibrate and shake the debris (such as stones) in its filter holes, thus preventing it from accumulating too much and causing blockage.
[0035] When the anti-clogging rod 16 descends to its lowest point, the elastic block 19 contacts the filter plate 4 and undergoes a certain deformation.
[0036] The elastic block 19 is preferably made of rubber.
[0037] The working principle of this utility model is as follows: The filter box 3 is placed in the aquaculture pond, and the water pump 1 is turned on to draw water through the water pipe 2. The pond water is filtered through the filter plate 4 (blocking debris such as gravel and aquatic plants) and then enters the filter box 3. It is then discharged by the water pump 1 through the water pipe 2. To prevent the filter plate 4 from clogging, the telescopic cylinder 7 of the cleaning mechanism 5 drives the brush plate 8 to move back and forth, using its bristles to clean the debris accumulated on the lower surface of the filter plate 4. At the same time, the motor 12 of the anti-clogging mechanism 10 drives the cam 13 to rotate, periodically pressing down the upper end of the anti-clogging rod 16. This causes the anti-clogging rod 16 to overcome the resistance of the spring 18 and drive the elastic block 19 at its lower end to strike the upper surface of the filter plate 4, generating vibration to shake off the debris stuck in the filter holes. After that, the spring 18 pushes the anti-clogging rod 16 and the elastic block 19 to reset. This cycle repeats, thereby achieving continuous surface cleaning and deep anti-clogging, ensuring smooth drainage and the safety of the water pump 1.
