Description

Technical Field

[0001] This utility model relates to the field of aquaculture water treatment devices, specifically to a fish pond anti-escape central pipe. Background Technology

[0002] Currently, with the significant increase in demand for aquatic products, traditional pond aquaculture can no longer meet market demand, leading to the rapid development of factory-style aquaculture. Factory-style aquaculture uses culture tanks, containers, and ponds, employing a fully enclosed water circulation system for intensive aquaculture. This significantly reduces the land area required for aquaculture, resulting in less water consumption, less pollution, and less susceptibility to geographical influences. In factory-style recirculating aquaculture, uneaten feed and feces are primarily discharged through the central outlet pipe of the pond. If uneaten feed and feces are not discharged in a timely manner, they will accumulate and ferment, producing harmful substances and deteriorating water quality. Therefore, rapid discharge of uneaten feed and feces is crucial to ensuring water quality in the pond. As the stocking density increases, the amount of feed required also increases, resulting in more uneaten feed and feces. Therefore, the design of the central outlet pipe is extremely important. The central outlet pipe, also known as the "central pipe," is designed to facilitate the rapid discharge of waste from the pond.

[0003] In the process of raising fish fry, bottom drainage and escape prevention in the breeding pond are both issues that need to be considered. The existing technology mainly uses bottom drainage to discharge water from the bottom of the pond, while the top drainage method is used directly when raising fish fry. This cannot meet the needs of bottom drainage and escape prevention at the same time. Summary of the Invention

[0004] The purpose of this utility model is to provide a fish pond escape prevention central pipe that can solve the problem that the central pipe of traditional aquaculture ponds cannot simultaneously meet the needs of sewage discharge and fish fry escape prevention.

[0005] The technical solution adopted in this utility model is as follows:

[0006] An escape-prevention central pipe for fish ponds includes a central main pipe, a bottom escape-prevention component, a middle escape-prevention component, a top escape-prevention component, and a lifting component. The lower end of the central main pipe is connected to the drain pipe of the fish pond, and its top does not exceed the water surface of the fish pond. The central main pipe forms a cavity that runs from top to bottom. Bottom water outlet channel, middle water outlet channel, and top water outlet channel are respectively provided at the bottom, middle, and top parts of the central main pipe. The bottom water outlet channel, middle water outlet channel, and top water outlet channel are all connected to the cavity. The bottom water outlet channel, middle water outlet channel, and top water outlet channel are evenly provided with a matrix of through holes. The lifting component includes a motor, a steel wire rope, and a pulley. A mounting frame is provided at the top of the central main pipe. The motor is mounted on the mounting frame through a support plate. A take-up reel is mounted on the motor. The mounting frame is provided with multiple mounting slots. The pulley is installed in the mounting slots. One end of the steel wire rope is fixed to the take-up reel of the motor, and the other end passes through the pulley and is connected to the bottom escape-prevention component, the middle escape-prevention component, and the top escape-prevention component, respectively.

[0007] Furthermore, the bottom escape prevention component is located at the lower end of the central main pipe. The bottom escape prevention component includes a bottom support filter cover and a bottom filter block. The bottom support filter cover has a trumpet-shaped cover structure and is fixed to the central main pipe. The bottom end of the bottom support filter cover covers the bottom of the fish pond to prevent fish from entering the filter cover. The lower end of the bottom support filter cover is provided with a matrix of water guide holes. The bottom filter block is slidably sleeved on the outside of the bottom support filter cover and can move up and down along the surface of the bottom support filter cover. The lower end of the bottom filter block is provided with multiple filter windows, and filter screens are provided on the filter windows. The steel wire rope is connected to the bottom filter block.

[0008] Furthermore, the height of the water guide hole is consistent with that of the bottom water outlet channel.

[0009] Furthermore, the middle-layer anti-escape component is installed on the middle water outlet channel. The middle-layer anti-escape component includes a middle-layer filter block, a middle-layer upper limit plate, and a middle-layer lower limit plate. The middle-layer upper limit plate and the middle-layer lower limit plate are both ring-shaped partition structures. The middle-layer upper limit plate is located at the upper edge of the middle water outlet channel, and the middle-layer lower limit plate is located at the lower edge of the middle water outlet channel. The middle-layer filter block is slidably sleeved on the outside of the middle water outlet channel, and the middle-layer filter block is located between the middle-layer upper limit plate and the middle-layer lower limit plate. A filter screen is provided on the inner wall of the middle-layer filter block, and the steel wire rope is connected to the middle-layer filter block.

[0010] Furthermore, the distance between the upper limit plate and the lower limit plate of the middle layer is the height of the middle layer filter block plus the height of the middle water outlet channel.

[0011] Furthermore, multiple springs are also provided between the upper limit plate and the lower limit plate of the middle layer. One end of the spring is fixed to the lower limit plate of the middle layer, and the other end is fixed to the middle of the middle layer filter block.

[0012] Furthermore, the structure of the upper anti-escape component is the same as that of the middle anti-escape component. The upper anti-escape component is installed on the upper water outlet channel and includes an upper filter block, an upper upper limit plate, and an upper lower limit plate. The upper upper limit plate and the upper lower limit plate are both ring-shaped partition structures. The upper upper limit plate is located at the upper edge of the upper water outlet channel, and the upper lower limit plate is located at the lower edge of the upper water outlet channel. The upper filter block is slidably sleeved on the outside of the upper water outlet channel and is located between the upper upper limit plate and the upper lower limit plate. A filter screen is provided on the inner wall of the upper filter block, and the steel wire rope is connected to the upper filter block.

[0013] Furthermore, the distance between the upper limit plate and the upper lower limit plate is the height of the upper filter block plus the height of the water outlet channel.

[0014] Furthermore, multiple springs are provided between the upper lower limit plate and the upper filter block, with one end of the spring fixed to the upper lower limit plate and the other end fixed to the middle of the upper filter block.

[0020] 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. In the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0021] like Figure 1 , Figure 3 As shown, a fish pond escape prevention central pipe includes a central main pipe 1, a bottom escape prevention component 2, a middle escape prevention component 3, an upper escape prevention component 4, and a lifting component 5. The lower end of the central main pipe 1 is connected to the drain pipe of the fish pond, and its top does not exceed the water surface of the fish pond. The central main pipe 1 forms a cavity 11 that runs from top to bottom. The bottom, middle, and upper parts of the central main pipe 1 are respectively provided with a bottom water outlet channel 12, a middle water outlet channel 13, and an upper water outlet channel 14. The bottom water outlet channel 12, the middle water outlet channel 13, and the upper water outlet channel 14 are all provided with the same structure. Both channel 13 and upper water outlet channel 14 are connected to cavity 11. The bottom water outlet channel 12, middle water outlet channel 13 and upper water outlet channel 14 are evenly provided with matrix-like through holes. The bottom water and impurities of the fish pond enter the cavity 11 through the bottom water outlet channel 12, the middle water and impurities of the fish pond enter the cavity 11 through the middle water outlet channel 13, and the water and impurities of the upper part of the fish pond enter the cavity 11 through the upper water outlet channel 14, thereby realizing the simultaneous discharge of water and impurities from the upper, middle and lower parts of the fish pond.

[0022] The bottom escape prevention component 2 is installed on the bottom water outlet channel 12. The bottom escape prevention component 2 includes a bottom support filter cover 21 and a bottom filter block 22. The bottom support filter cover 21 has a trumpet-shaped structure and is fixed to the central main pipe 1. The bottom end of the bottom support filter cover 21 covers the bottom of the fishpond to prevent fish from entering the filter cover. A matrix of water guide holes 211 is provided at the lower end of the bottom support filter cover 211. Water and impurities enter the cover through the water guide holes 211 and then enter the central main pipe 1 through the bottom water outlet channel 12. The height of the water guide holes 211 is the same as that of the bottom water outlet channel 12 to facilitate the entry of impurities into the central main pipe 1. The bottom filter block 22 is slidably sleeved on the outside of the bottom support filter cover 21 and can move up and down along the surface of the bottom support filter cover 21. The bottom filter block 22 is made of metal. Made of materials, the bottom filter block 22 can automatically fit onto the surface of the bottom support filter cover 21 under gravity. When the bottom filter block 22 slides down to the bottom, it covers the lower end of the bottom support filter cover 21. The bottom of the bottom filter block 22 is provided with multiple filter windows 221, and filter screens are provided on the filter windows 221. When the bottom filter block 22 slides down to the bottom of the bottom support filter cover 21, the filter windows 221 correspond to the water guide holes 211. The mesh size of the filter screen can be set according to the size of the fish fry, so that impurities in the water can pass through while isolating the fish fry in the fish pond to prevent them from escaping. For example, when the main species being fish fry is fish, the mesh size of the filter screen can be set to 60 mesh. Since the fish fry are relatively small, the feed and excrement particles they eat are relatively small, and water and solid particle impurities can pass through the filter screen and flow out. As the fish fry grow larger...

[0023] The middle-layer escape prevention component 3 is installed on the middle water outlet channel 13. The middle-layer escape prevention component 3 includes a middle-layer filter block 31, a middle-layer upper limit plate 32, and a middle-layer lower limit plate 33. Both the middle-layer upper limit plate 32 and the middle-layer lower limit plate 33 are annular partition structures. The middle-layer upper limit plate 32 is located at the upper edge of the middle water outlet channel 13, and the middle-layer lower limit plate 33 is located at the lower edge of the middle water outlet channel 13. The middle-layer filter block 31 is slidably fitted onto the outside of the middle water outlet channel 13, and is located between the middle-layer upper limit plate 32 and the middle-layer lower limit plate 33. A filter screen is provided on the inner wall of the middle-layer filter block 31. The mesh size of the filter screen can be set according to the size of the fish fry, allowing impurities in the water to pass through while simultaneously filtering out... Fish fry are isolated in the fishpond to prevent them from escaping. The upper limit plate 32 and the lower limit plate 33 of the middle layer limit the maximum stroke of the middle layer filter block 31. Therefore, the distance between the upper limit plate 32 and the lower limit plate 33 is the height of the middle layer filter block 31 plus the height of the middle water outlet channel 13. When the middle layer filter block 31 slides onto the lower limit plate 33, it can completely cover the through hole of the middle water outlet channel 13. At this time, water and small particulate impurities can enter the cavity 11 through the filter screen, and the fish fry are blocked in the fishpond. When the middle layer filter block 31 slides onto the upper limit plate 32, the through hole of the middle water outlet channel 13 is fully opened, and the middle layer water and impurities can enter the cavity 11 through the through hole.

[0024] The structure of the upper anti-escape component 4 is the same as that of the middle anti-escape component 3. The upper anti-escape component 4 is installed on the upper water outlet channel 14. The upper anti-escape component 4 includes an upper filter block 41, an upper upper limit plate 42, and an upper lower limit plate 43. The upper upper limit plate 42 and the upper lower limit plate 43 are both annular partition structures. The upper upper limit plate 42 is located at the upper edge of the upper water outlet channel 14, and the upper lower limit plate 43 is located at the lower edge of the upper water outlet channel 14. The upper filter block 41 is slidably sleeved on the outside of the upper water outlet channel 14, and the upper filter block 41 is located between the upper upper limit plate 42 and the upper lower limit plate 43. A filter screen is provided on the inner wall of the upper filter block 41. The mesh size of the filter screen can be set according to the size of the fish fry. It allows impurities in the water to pass through while isolating fish fry within the fishpond to prevent them from escaping. The upper limit plate 42 and the upper lower limit plate 43 limit the maximum travel of the upper filter barrier 41. Therefore, the distance between the upper limit plate 42 and the upper lower limit plate 43 is the height of the upper filter barrier 41 plus the height of the water outlet channel 14. When the upper filter barrier 41 slides onto the upper lower limit plate 43, it completely covers the through hole of the upper water outlet channel 14. At this time, water and small particles can enter the cavity 11 through the filter screen, and the fish fry are blocked in the fishpond. When the upper filter barrier 41 slides onto the upper limit plate 42, the through hole of the upper water outlet channel 14 is fully opened, and the middle layer of water and impurities can enter the cavity 11 through the through hole.

[0025] The lifting component 5 is used to control the up-and-down movement of the bottom anti-escape component 2, the middle anti-escape component 3, and the top anti-escape component 4. The lifting component 5 includes a motor 51, a wire rope 52, and pulleys 53. A mounting frame 54 is provided at the top of the central main pipe 1. The motor 51 is mounted on the mounting frame 54 via a support plate. A take-up reel is mounted on the motor 51. The mounting frame 54 is provided with multiple mounting slots, and the pulleys 53 are installed in the mounting slots. The number of pulleys 53 can be 3-6 as needed. In this embodiment, the number of pulleys 53 is [not specified]. There are three steel wire ropes 52, the number of which is the same as the number of pulleys 53. One end of each steel wire rope 52 is fixed to the take-up reel of the motor 51, and the other end passes through the pulley 53. From top to bottom, they are connected and fixed to the upper filter barrier 41, the middle filter barrier 31, and the bottom filter barrier 22 respectively. When the motor 51 starts, the steel wire rope 52 is wound around the take-up reel. Since the upper filter barrier 41, the middle filter barrier 31, and the bottom filter barrier 22 are all fixed on the same steel wire rope 52, when the take-up reel winds up, the upper filter barrier 41, the middle filter barrier 31, and the bottom filter barrier 22 are all wound around the same steel wire rope 52. The block 31 and the bottom filter block 22 can move simultaneously. To enable the upper filter block 41 and the middle filter block 31 to quickly return to their original positions, multiple springs 55 are provided between the upper lower limit plate 43 and the upper filter block 41. The number of springs 55 is preferably 2-3. One end of each spring 55 is fixed to the upper lower limit plate 43, and the other end is fixed to the middle of the upper filter block 41. When the upper filter block 41 moves to the position of the upper upper limit plate 42, the spring 55 provides a continuous downward pulling force. When the motor 52 releases the wire, the spring... Spring 55 can quickly pull the upper filter block 41 back to the upper lower limit plate 43; similarly, multiple springs 55 are also provided between the middle upper limit plate 32 and the middle lower limit plate 33. One end of the spring 55 is fixed to the middle lower limit plate 33, and the other end is fixed to the middle of the middle filter block 31. When the middle filter block 31 moves up to the position of the middle upper limit plate 32, the spring 55 provides a continuous downward pulling force. When the motor 52 releases the wire, the spring 55 can quickly pull the middle filter block 31 back to the middle lower limit plate 33.

[0026] The working principle of this utility model is as follows:

[0027] When the fishpond is filled with fish fry, because the fry are small, the food they eat and the excrement they produce are also small particles. Solid particles and impurities can pass through the filter screen and flow out. The motor 51 is started to release the line, so that the bottom filter block 22 fits onto the surface of the bottom support filter cover 21. At the same time, the upper filter block 41 covers the upper water outlet channel 14, and the middle filter block 31 covers the middle water outlet channel 13. At this time, water and impurities can pass through the filter screen and flow into the central pipe and out. When the fishpond needs to be cleaned, after the fish fry are transferred out, the motor 51 is started, and the wire rope 52 is wound around the reel. The upper filter block 41, the middle filter block 31, and the bottom filter block 22 move upward simultaneously. When the motor 51 is activated, the bottom outlet channel 12, the middle outlet channel 13, and the top outlet channel 14 open simultaneously. The impurities washed out flow out through the through holes into the central main pipe 1. After the cleaning is completed, the motor 51 reverses to release the line, and the spring 55 quickly pulls back the upper filter barrier 41 and the middle filter barrier 31 to cover the top outlet channel 14 and the middle outlet channel 13. At the same time, the bottom filter barrier 22 can automatically fit onto the surface of the bottom support filter cover 21 under the action of gravity. When the fish grows, the feed and the fecal particles produced also become larger, and the upper filter barrier 41, the middle filter barrier 31, and the bottom filter barrier 22 can be opened directly, and water and impurities can be discharged directly from the outlet channel.

[0028] This utility model sets up a bottom water outlet channel, a middle water outlet channel and an upper water outlet channel on the central main pipe, and respectively sets up movable and closable upper layer filter barrier, middle layer filter barrier and bottom surface filter barrier on the above water outlet channels. The filter screen on the filter barrier prevents fish from entering the central pipe, which can prevent fish from escaping, and at the same time ensure the drainage of the bottom, middle and upper layers of the fish pond.

[0029] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
