Description

Technical Field

[0001] This utility model belongs to the field of aquaculture technology, specifically a drainage device for fish fry breeding ponds. Background Technology

[0002] Aquaculture refers to the cultivation of fish or various seafood in artificially created fishponds on land for consumption. Depending on the quality of the water, it can be divided into three main categories: freshwater aquaculture, saltwater aquaculture, and marine aquaculture. Among them, fish fry cultivation is particularly important. In the process of raising fish fry in pond water, the water quality often deteriorates due to long-term cultivation, requiring regular drainage and replacement of the pond water.

[0003] However, existing pond drainage systems still have some shortcomings. During use, aquatic plants and other debris in the pond can easily clog the drainage system, affecting its operation.

[0004] For example, utility model publication CN219939387U discloses a pond drainage device for aquaculture, including a drainage box. A partition plate is fixedly connected to the inner wall of the drainage box, and a high-efficiency pond drainage mechanism is provided on the top of the partition plate. One end of a drive rod is fixedly connected to the output end of a submersible motor, and one end of a cutting blade is fixedly connected to the outer wall of the drive rod at equal intervals. During drainage, the submersible motor is started to drive the drive rod to rotate, and the drive rod drives the cutting blade to efficiently cut aquatic plants and drive away impurities near the filter plate. An air cushion is installed at the bottom of the drainage box, and an air pump is installed on the top inner side of the drainage box. The output end of the air pump is connected to the air inlet of the air cushion. According to the depth of the pond, the air cushion is inflated and deflated by starting the air pump, which allows for convenient depth adjustment of the device and improves its practicality.

[0005] However, the above-mentioned device does not have anti-clogging measures for the filter screen during use. When the impurities are cut by the driving rod and the cutting knife, the impurities are easily moved to one side of the filter screen by the action of the water pump and are adsorbed on the surface of the filter screen, causing the filter screen to be blocked. If the filter screen is not cleaned in time, it will easily lead to the filter screen being blocked and affecting the drainage efficiency. Therefore, a drainage device for fish fry breeding ponds is proposed to solve the problems mentioned in the background technology. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides a drainage device for fish fry breeding ponds, which solves the problem that existing drainage devices are prone to clogging the filter screen with impurities, resulting in low drainage efficiency.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a drainage device for a fish fry breeding pond, comprising a drainage box, a drainage mechanism provided inside the drainage box, a filter pipe fixedly connected to the side of the drainage box, a suction pipe including a water suction pipe fixedly connected to the filter pipe, a water pump fixedly connected to the end of the water suction pipe away from the filter pipe, a drainage pipe fixedly connected to the top of the water pump, and an anti-clogging mechanism provided on the filter pipe;

[0008] The anti-clogging mechanism includes a water wheel, a drive rod fixedly connected to the center of the water wheel, the drive rod being rotatably connected to the side of the filter pipe away from the drainage tank, a screw installed inside the filter pipe, the screw and the drive rod being at the same horizontal position, a circular plate fixedly connected to the side of the screw near the drive rod, and a fixing frame fixedly connected to both the circular plate and the side of the screw away from the drive rod, the fixing frame being fixedly connected to the inner wall of the filter pipe on the side away from the outer wall of the screw, an electric push rod fixedly connected to the circular plate, a circular ring block fixedly connected to the side of the electric push rod away from the circular plate, and a cleaning assembly installed on the screw.

[0009] Preferably, the cleaning assembly includes a movable block that slides on a screw. The movable block is fixedly connected to a plurality of connecting rods arranged in a circular array from its side wall. Each connecting rod is fixedly connected to a cleaning block on the side away from the movable block. The movable block has a circular groove on the side near the electric push rod, and the circular groove is connected to a bearing.

[0010] Preferably, the filter tube is provided with a striking component for striking the filter tube, and the striking component is distributed in a circumferential array on the outer wall of the filter tube.

[0011] Preferably, the striking assembly includes a striking block, a spring is fixedly connected to the side of the striking block away from the filter tube, a fixing block is fixedly connected to the other end of the spring away from the striking block, and an adjusting block is fixedly connected to the side of the fixing block near the drain tank.

[0012] Preferably, a mounting block is fixedly connected to one side of the drain tank located on the filter pipe, and the mounting block is provided with a transmission component for driving the adjusting block to make circular motion.

[0013] Preferably, the transmission component includes a circular block, on the side of which at least four protrusions are fixedly connected in a circumferential array, and a rotating shaft is fixedly connected at the center of the protrusions. An adjusting block and a slider are fixedly connected at both ends of the rotating shaft, and the circular block is rotatably connected to the mounting block.

[0014] Preferably, the mounting block has an annular groove, the slider slides along the annular groove, and a connecting frame that is fixedly connected to the drive rod is fixedly connected to the annular block.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention utilizes a water wheel, cleaning assembly, transmission assembly, and connecting frame to prevent filter tube clogging. Water flow drives the water wheel to rotate, which in turn drives the drive rod to rotate. This, in conjunction with an electric push rod, moves the circular locking block, causing the moving block to slide on the screw. Simultaneously, the moving block rotates along the screw thread, causing the cleaning block to rotate and advance inside the filter tube. The connecting frame also drives the circular block to rotate, causing the protrusion to rotate as well. This, in turn, causes the entire striking block to perform a circular motion outside the filter tube. As both rotate, the through-hole needle at the bottom of the striking block magnetically attracts the cleaning block, achieving both perforation and vibration of the filter tube. This solves the problem of existing drainage devices easily clogging the filter screen with impurities, resulting in low drainage efficiency. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1 to 7 As shown, this utility model provides a drainage device for a fish fry breeding pond, including a drainage box 1. A drainage mechanism 2 is installed inside the drainage box 1. A filter pipe 3 is fixedly connected to the side of the drainage box 1. The drainage mechanism 2 includes a suction pipe 21, which is fixedly connected to the filter pipe 3. A water pump 22 is fixedly connected to the end of the suction pipe 21 away from the filter pipe 3. A drainage pipe 23 is fixedly connected to the top of the water pump 22. An anti-clogging mechanism 4 is installed on the filter pipe 3. The anti-clogging mechanism 4 includes a water wheel 41. A drive rod 411 is fixedly connected to the center of the water wheel 41. The drive rod 411 is rotatably connected to the side of the filter pipe 3 away from the drainage box 1. A screw 412 is installed inside the filter pipe 3. The screw 412 and the drive rod 411 are at the same horizontal position. A circular plate 416 is fixedly connected to the side of the screw 412 near the drive rod 411. Both the circular plate 416 and the side of the screw 412 away from the drive rod 411 are fixedly connected to... A fixed frame 415 is provided, with the side of the fixed frame 415 away from the outer wall of the screw 412 being fixedly connected to the inner wall of the filter tube 3. An electric push rod 413 is fixedly connected to the circular plate 416, and a circular ring block 414 is fixedly connected to the side of the electric push rod 413 away from the circular plate 416. A cleaning assembly 42 is provided on the screw 412, which includes a moving block 421 that slides on the screw 412. Multiple connecting rods 422 arranged in a circular array are fixedly connected to the side wall of the moving block 421. A cleaning block 423 is fixedly connected to the side of the connecting rods 422 away from the moving block 421. A circular ring groove 424 is provided on the side of the moving block 421 near the electric push rod 413. The circular ring block 414 is connected to the circular ring groove 424 by a bearing. A striking assembly 43 for striking the filter tube 3 is provided on the outside of the filter tube 3, and the striking assembly 43 is arranged in a circumferential array on the outer wall of the filter tube 3.

[0027] The above scheme is adopted as follows: During use, the drainage mechanism 2 and the water pump 22 are used to discharge water from the aquaculture pond through the suction pipe 21 and the drainage pipe 23. During drainage, the suction force brought by the water pump 22 causes the water flow to be concentrated on one side of the filter pipe 3, which in turn drives the water wheel 41 and the drive rod 411 to rotate, which facilitates the operation of the subsequent striking component 43. At this time, the electric push rod 413 pushes the ring block 414 to move, which in turn drives the moving block 421 to slide along the screw 412 and rotates along the thread direction of the screw 412. During this process, the ring block 414 rotates in the ring groove 424, which drives the connecting rod 422 and the cleaning block 423 to rotate and slide along the screw 412. Since the cleaning block 423 is a positive magnetic block, it can be used in conjunction with the striking component 43 to achieve vibration and striking of the filter pipe 3, thereby preventing the filter pipe 3 from clogging.

[0028] like Figures 3 to 6 As shown, the striking component 43 includes a striking block 431. A spring 432 is fixedly connected to the side of the striking block 431 away from the filter tube 3. A fixing block 433 is fixedly connected to the other end of the spring 432 away from the striking block 431. An adjusting block 434 is fixedly connected to the side of the fixing block 433 near the drain tank 1. An installation block 11 is fixedly connected to the side of the drain tank 1 located on the filter tube 3. A transmission component 44 for driving the adjusting block 434 to make circular motion is provided on the installation block 11.

[0029] The above scheme is adopted: the transmission component 44 drives the striking component 43 to rotate while striking the filter tube 3. Since the bottom of the striking block 431 is fixedly provided with multiple through-hole pins, it can be attracted to the magnetic cleaning block 423. When the cleaning block 423 passes by, it drives the through-hole pins on the striking block 431 to vibrate and open the filter tube 3. When the cleaning block 423 is removed, the striking block 431 is reset and moves away from the filter tube 3 under the action of the spring 432.

[0030] like Figure 4 As shown, the transmission assembly 44 includes a ring block 444. At least four protrusions 441 arranged in a circular array are fixedly connected to the side of the ring block 444. A rotating shaft 442 is fixedly connected to the center of the protrusions 441. An adjusting block 434 and a slider 443 are fixedly connected to both ends of the rotating shaft 442, respectively. The ring block 444 is rotatably connected to the mounting block 11. A ring groove 111 is provided on the mounting block 11. The slider 443 slides along the ring groove 111. A connecting bracket 45 is fixedly connected to the ring block 444 and is fixedly connected to the drive rod 411.

[0031] The above solution is adopted: by using the transmission component 44, when the drive rod 411 rotates, it can drive the connecting frame 45 to rotate, which in turn drives the ring block 444 to rotate, which in turn drives the protrusion 441 to rotate synchronously, so that the slider 443 moves along the ring groove 111, thereby driving the entire adjusting block 434 and the fixed block 433 to rotate, so that the entire striking block 431 rotates and strikes along the outside of the filter tube 3, thereby achieving anti-clogging.

[0032] The working principle and usage process of this utility model are as follows: When using this utility model, the device is carried to the pond where it is needed and placed at the bottom of the pond. Water is pumped from the pond through the suction pipe 21 using the water pump 22 and drained through the drain pipe 23. During drainage, the water flow drives the water wheel 41, the drive rod 411, and the connecting frame 45 to rotate. Simultaneously, the electric push rod 413 pushes the annular locking block 414 to move, thereby causing the moving block 421 to slide along the screw 412 and rotate along the thread direction of the screw 412. During this process, the annular locking block 414 rotates in the annular locking groove 424, causing the connecting rod 422 and the cleaning block 423 to slide along the screw 412. Since the cleaning block 423 is a positive magnetic block, it can attract the through-hole needle at the bottom of the striking block 431. When the cleaning block 423 passes by, it causes the through-hole needle on the striking block 431 to approach the cleaning block 423, thus cleaning the filter tube 3. The vibrating through-hole, when the cleaning block 423 is removed, the striking block 431 is reset and moves away from the filter tube 3 under the action of the spring 432, realizing the vibration striking of the filter tube 3. At the same time, the connecting bracket 45 can drive the ring block 444 to rotate, which in turn drives the protrusion 441 to rotate, so that the entire adjusting block 434 and the fixing block 433 move in a circle along the filter tube 3, so that the entire striking block 431 rotates and strikes along the outside of the filter tube 3, thereby realizing the anti-clogging of the filter tube 3. Among them, the electric push rod 4 The reciprocating motion of the 13 ring block 414 and the moving block 421 causes the ring block 414 and the ring groove 424 to rotate in a forward and reverse cycle, which in turn causes the cleaning block 423 on the surface to rotate along the inner wall of the filter tube 3 while reciprocating, achieving a cyclical impact effect. The filter tube 3 can isolate most aquatic plants. At the same time, due to the fast water flow, less impurities enter the interior of the filter tube 3 and are difficult to stay at the screw 412, so as not to cause the screw 412 to get stuck.
