Description

Technical Field

[0001] This invention relates to the field of aquaculture technology, specifically to a drainage tool for artificial aquaculture ponds. Background Technology

[0002] In artificial aquaculture (such as freshwater fish, shrimp, crab, and shellfish farming), drainage is a core element in ensuring a stable aquaculture environment and achieving production management (such as pond cleaning, seedling separation, water exchange, and harvesting).

[0003] When draining aquaculture ponds, a screen is typically installed inside the pond and connected to the drain pipe. A cylindrical tube is then placed inside the screen, followed by an inner tube inserted into the screen. When the water level in the pond exceeds the height of the inner tube, the water passes through the screen, between the inner and cylindrical tubes, and is discharged outwards through the inner tube. As the water flows through the screen, it carries away feces, uneaten feed, plant debris, and other impurities. Because the screen is located at the bottom of the pond, the water flow is relatively slow, which can easily lead to sediment buildup and blockage of the screen as the water automatically drains through the inner tube. This affects the flow and smoothness of the drainage process and can even cause the drainage system to fail. Summary of the Invention

[0004] The purpose of this invention is to provide a drainage tool for artificial aquaculture ponds to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] The present invention is a drainage tool for artificial aquaculture ponds, comprising a main body, a grid cylinder slidably connected to the top of the main body, and a plurality of rectangular through grooves formed on the outer surface of the grid cylinder, the rectangular through grooves being wider on the outside and narrower on the inside, and also including;

[0007] A sliding mechanism is installed inside the bar screen cylinder to prevent blockage on the outside of the rectangular channel during drainage.

[0008] An auxiliary mechanism is installed on the side wall of the sliding mechanism to ensure the stability of the waterproofing during manual waterproofing.

[0009] Furthermore, the main body includes an outer cylinder slidably connected inside the grid cylinder, and an inner cylinder slidably connected inside the grid cylinder. The main body also includes:

[0010] A flip-over assembly is installed inside the grid cylinder;

[0011] The active component is mounted on the side wall of the flip component.

[0012] Furthermore, the sliding mechanism includes several telescopic plates disposed inside the grid cylinder, and the sliding mechanism also includes:

[0013] The limiting component is installed on the side wall of the telescopic plate.

[0014] Furthermore, the auxiliary mechanism includes a spring telescopic shaft disposed on the side wall of the telescopic plate, and the auxiliary mechanism also includes:

[0015] The rotating assembly is installed at the bottom of the spring telescopic shaft.

[0016] Furthermore, the flipping assembly includes several flipping plates rotatably connected to the inner wall at the bottom of the grid cylinder. The flipping plates are arranged in a circular array around the center of the grid cylinder. Long rods are rotatably connected to the side walls of the flipping plates, and two short shafts are fixedly connected to the left and right sides of the long rods.

[0017] Furthermore, the active component includes a sliding plate 1 slidably connected to the outer surfaces of the two short shafts, and a bent plate 1 is fixedly connected to the side of the sliding plate 1 near the grid cylinder.

[0018] The side of the bent plate away from the sliding plate is slidably connected to the inner wall of the grid cylinder;

[0019] A second sliding plate is slidably connected to the side of the bending plate near the short axis, and the end of the second sliding plate away from the inner cylinder is fixedly connected to the inner wall of the grid cylinder.

[0020] Furthermore, the telescopic plate is slidably connected to the outer surface of the long rod;

[0021] Limiting plates are rotatably connected to both the left and right sides of the telescopic plate, and the end of the limiting plate away from the outer cylinder is fixedly connected to the inner wall of the grid cylinder.

[0022] Furthermore, a vertical plate is rotatably connected to the side of the telescopic plate near the limiting plate, and a fixed ring is rotatably connected to the top of several vertical plates, with a floating ring fixedly connected to the top of the fixed ring.

[0023] Furthermore, a fixed rod is fixedly connected to the side of the telescopic plate away from the vertical plate, and the spring telescopic shaft is rotatably connected to the outer surface of the fixed rod;

[0024] The rotating assembly includes a rectangular frame disposed on the outer surface of the spring telescopic shaft, and the bottom of the spring telescopic shaft is fixedly connected to the rectangular frame.

[0025] Furthermore, an arc-shaped plate is fixedly connected to the bottom of the rectangular frame. Several J-shaped grooves are opened on the side of the arc-shaped plate near the grid cylinder. Three flexible layers are fixedly connected to the side of the arc-shaped plate away from the J-shaped grooves. The flexible layers are connected to the J-shaped grooves.

[0026] The present invention has the following beneficial effects:

[0027] 1. In this invention, when the water continues to flow upward between the outer and inner cylinders, the upward-flowing water will be guided by the bent plate, causing some of the water to flow back. At this time, the backflowing water will interact and collide with the upward-flowing water, forming a backflow force from the inside to the outside at the rectangular through-slot on the grid cylinder. By backflowing the rectangular through-slot on the grid cylinder, the blockage of the grid cylinder by sediment and impurity particles in the pond when the water flows at the bottom of the aquaculture pond can be further reduced, the flow area of ​​the water during drainage can be increased, and the drainage time can be reduced, the unobstructedness of the drainage channel can be improved, and the drainage efficiency of the aquaculture pond can be improved.

[0028] 2. In this invention, when the arc-shaped plate is subjected to the downward pressure of the water flow, it is transmitted to the inner cylinder. The covering of the inner cylinder by multiple arc-shaped plates and the downward pressure generated on the inner cylinder can enhance the stability of the inner cylinder's position. This reduces the possibility of the inner cylinder swaying or shifting in position due to the interaction and collision of the water flow and the buoyancy in the water over a long period of time. Consequently, it reduces the possibility of water leakage through the outer cylinder when the water flows upward between the inner and outer cylinders due to the swaying of the outer cylinder's position. This maintains the uniformity of the water flow channel while ensuring stability during and before and after drainage, thereby improving drainage efficiency.

[0029] 3. This invention strengthens the contact strength and bonding surface between the arc-shaped plate and the inner cylinder through a flexible layer. When water flows and impacts the J-shaped groove, and exerts downward pressure on the inner cylinder through the flexible layer, it ensures the sliding strength of the inner cylinder driven by the arc-shaped plate when it is pressed down. This reduces the possibility of loose bonding and sliding between the arc-shaped plate and the inner cylinder due to water flow collision and buoyancy. As a result, it further enhances the fixing strength of the inner cylinder when the arc-shaped plate is subjected to downward pressure, and enhances the stability of the inner cylinder during drainage.

[0030] 4. This invention, through the inclined guidance of the arc-shaped plate, can reduce water flow collisions and turbulence formation while ensuring stable outward discharge of water. At the same time, when the water flows into the interior of the inclined J-shaped channel, the top water flow area located at the discharge point will be guided by the J-shaped channel to flow back again. Simultaneously, the backflowing water will impact the outside of the grid cylinder again, thereby further reducing the adhesion and blockage of impurities in the rectangular through-slots on the grid cylinder, further enhancing the stability of water flow during outward drainage, increasing the flow area during drainage, and further shortening the drainage time.

[0031] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] Please see Figure 1 - Figure 11 As shown, the present invention is a drainage tool for artificial aquaculture ponds, including a main body 1, a grid cylinder 101 slidably connected to the top of the main body 1, a plurality of rectangular through grooves being formed on the outer surface of the grid cylinder 101, the rectangular through grooves being in a state of being wider on the outside and narrower on the inside, and also including;

[0048] Sliding mechanism 2 is installed inside the grid cylinder 101 to prevent blockage on the outside of the rectangular channel during drainage;

[0049] Auxiliary mechanism 3 is installed on the side wall of sliding mechanism 2 to ensure the stability of waterproofing during manual waterproofing.

[0050] The main body 1 includes an outer cylinder 102 slidably connected inside the grid cylinder 101, and an inner cylinder 103 slidably connected inside the grid cylinder 101. The main body 1 also includes:

[0051] The flipping assembly 11 is installed inside the grid cylinder 101;

[0052] The active component 12 is installed on the side wall of the flip component 11.

[0053] The sliding mechanism 2 includes a plurality of telescopic plates 201 disposed inside the grid cylinder 101, and the sliding mechanism 2 also includes:

[0054] Restriction component 21 is installed on the side wall of telescopic plate 201.

[0055] The auxiliary mechanism 3 includes a spring telescopic shaft 301 disposed on the side wall of the telescopic plate 201, and the auxiliary mechanism 3 also includes:

[0056] Rotating assembly 31 is installed at the bottom of spring telescopic shaft 301.

[0057] The flipping assembly 11 includes several flipping plates 111 rotatably connected to the inner wall of the bottom of the grid cylinder 101. The flipping plates 111 are arranged in a circular array around the center of the grid cylinder 101. A long rod 112 is rotatably connected to the side wall of the flipping plate 111. Two short shafts 113 are fixedly connected to the left and right sides of the long rod 112. When the water level in the aquaculture tank is higher than the inner cylinder 103, the water in the aquaculture tank will enter the space between the inner cylinder 103 and the outer cylinder 102 through the grid cylinder 101. The water level above the inner cylinder 103 will enter the main body 1 through the inner cylinder 103 and be discharged outward.

[0058] The active component 12 includes a sliding plate 121 that is slidably connected to the outer surfaces of two short shafts 113. A bent plate 122 is fixedly connected to the side of the sliding plate 121 near the grid cylinder 101.

[0059] The side of the bent plate 122 away from the sliding plate 121 is slidably connected to the inner wall of the grid cylinder 101;

[0060] A second sliding plate 123 is slidably connected to the side of the bending plate 122 near the short axis 113. The end of the second sliding plate 123 away from the inner cylinder 103 is fixedly connected to the inner wall of the grid cylinder 101. When the long rod 112 slides upward, the long rod 112 will drive the first sliding plate 121 to slide upward through the short axis 113. The top of the second sliding plate 123 is restricted by the second sliding plate 123.

[0061] The telescopic plate 201 is slidably connected to the outer surface of the long rod 112;

[0062] Limiting plates 211 are rotatably connected to both the left and right sides of the telescopic plate 201. The end of the limiting plate 211 away from the outer cylinder 102 is fixedly connected to the inner wall of the grid cylinder 101.

[0063] A vertical plate 212 is rotatably connected to the side of the telescopic plate 201 near the limiting plate 211. A fixing ring 213 is rotatably connected to the top of several vertical plates 212. A floating ring 214 is fixedly connected to the top of the fixing ring 213. When the floating ring 214 floats upward, it will drive the rear end of the telescopic plate 201 to rotate upward through the fixing ring 213 and the vertical plate 212. When the rear end of the telescopic plate 201 is pulled and rotates upward, the telescopic plate 201 will rotate around the connection point between the middle of the telescopic plate 201 and the limiting plate 211.

[0064] A fixed rod is fixedly connected to the side of the telescopic plate 201 away from the vertical plate 212, and the spring telescopic shaft 301 is rotatably connected to the outer surface of the fixed rod;

[0065] The rotating assembly 31 includes a rectangular frame 311 disposed on the outer surface of the spring telescopic shaft 301. The bottom of the spring telescopic shaft 301 is fixedly connected to the rectangular frame 311. When part of the rising water flow returns through the bend on the bending plate 122, the downward returning water flow will flow into the J-shaped groove 313. Since the bottom of the J-shaped groove 313 is in an upward bending state, when the water flow returns through the guidance of the bending plate 122, the returning water flow will impact the bending surface at the bottom of the J-shaped groove 313 and generate downward pressure and downward fixing force on the arc plate 312.

[0066] An arc-shaped plate 312 is fixedly connected to the bottom of the rectangular frame 311. Several J-shaped grooves 313 are opened on the side of the arc-shaped plate 312 near the grid cylinder 101. Three flexible layers 314 are fixedly connected on the side of the arc-shaped plate 312 away from the J-shaped grooves 313. The flexible layers 314 are connected to the J-shaped grooves 313. When the arc-shaped plate 312 is subjected to the downward pressure of the water flow, it will be transmitted to the inner cylinder 103. The inner cylinder 103 can be strengthened in position by the coverage of the inner cylinder 103 by the multiple arc-shaped plates 312 and the downward pressure generated on the inner cylinder 103.

[0067] In use, the main body 1 is first buried at the bottom of the center of the aquaculture pond. Then, according to the required water level, the height of the inner cylinder 103 is made to be level with the water level in the aquaculture pond. The length of the inner cylinder 103 is longer than that of the main body 103. After installing the outer cylinder 102 and the inner cylinder 103 with the grid cylinder 101, the bottom of the grid cylinder 101 is installed inside the main body 1. When the water level in the aquaculture pond is higher than the inner cylinder 103, the water in the aquaculture pond will enter between the inner cylinder 103 and the outer cylinder 102 through the grid cylinder 101. The water level above the inner cylinder 103 will enter the main body 1 through the inner cylinder 103 and be discharged outward. At the same time, when it is necessary to drain the water in the aquaculture pond, the staff will pull out the inner cylinder 103, and the water in the aquaculture pond will be discharged through the grid cylinder 101, thereby achieving the purpose of draining the aquaculture pond.

[0068] When the grid cylinder 101, outer cylinder 102, and inner cylinder 103 are placed in the water of the aquaculture pond, the floating ring 214 will float upward under the action of buoyancy in the water. When the floating ring 214 floats upward, it will drive the rear end of the telescopic plate 201 to rotate upward through the fixed ring 213 and the vertical plate 212. When the rear end of the telescopic plate 201 is pulled upward and rotates, the telescopic plate 201 will rotate around the connection point between the middle of the telescopic plate 201 and the limiting plate 211. At the same time, when the rear end of the telescopic plate 201 rotates upward, it will drive the tilting plate 111 to slide upward through the long rod 112. At this time, the tilting plate 111 will be in an inclined state. Figure 9As shown in the diagram, when the long rod 112 slides upward, it drives the sliding plate 121 to slide upward via the short shaft 113. Since the top of the sliding plate 123 is restricted by the sliding plate 123, when the sliding plate 121 slides upward, it drives the bottom of the bent plate 122 to slide upward along the inner wall of the grid cylinder 101. At this time, the top of the bent plate 122 will be in a bent state, exhibiting... Figure 9 In the current state, when the water level in the aquaculture tank is higher than the inner cylinder 103, the water in the bottom area of ​​the aquaculture tank will flow upward through the grid cylinder 101 and the outer cylinder 102 and the inner cylinder 103. At this time, the upward flowing water will be discharged through the top of the inner cylinder 103. Since the rectangular groove on the surface of the grid cylinder 101 is widening outward and narrowing inward, when the water flows through the narrower constriction section of the rectangular groove, the flow velocity increases and the pressure decreases. This will generate a suction force at the rectangular groove, which can prevent impurities in the water from adhering to the rectangular groove on the grid cylinder 101 and prevent impurities from adhering to the outside of the grid cylinder 101. At the same time, when the water flow continues... When the water flows upward between the outer cylinder 102 and the inner cylinder 103, the upward-flowing water is guided by the bent plate 122, causing some of the water to flow back. At this time, the backflowing water will interact and collide with the upward-flowing water, forming a backflow force from the inside to the outside at the rectangular through-slot on the grid cylinder 101. By backflowing the rectangular through-slot on the grid cylinder 101, the situation of sediment and impurity particles clogging the grid cylinder 101 when the water flows at the bottom of the aquaculture pond can be further reduced, the flow area of ​​the water during drainage can be increased, and the drainage time can be reduced, the unobstructedness of the drainage channel can be improved, and the drainage efficiency of the aquaculture pond can be improved.

[0069] When the rear end of the telescopic plate 201 rotates due to the upward pulling force of the floating ring 214, the upward rotation of the rear end of the telescopic plate 201 causes the front end of the telescopic plate 201 to rotate downward. When the front end of the telescopic plate 201 rotates downward, it drives the arc plate 312 to rotate downward through the spring telescopic shaft 301 and the rectangular frame 311. At the same time, it also causes the arc plate 312 to adhere to the outer surface of the inner cylinder 103. Meanwhile, when some of the rising water flows back through the bend on the bending plate 122, the downward flowing water flows into the J-shaped groove 313. Since the bottom of the J-shaped groove 313 is curved upward, when the water flows back guided by the bending plate 122, the backflowing water will affect the bend at the bottom of the J-shaped groove 313. The water flow impacts the curved plate 312, generating downward pressure and a downward fixing force. When the curved plate 312 is subjected to the downward pressure of the water flow, it is transmitted to the inner cylinder 103. The multiple curved plates 312 covering the inner cylinder 103 and the downward pressure generated on the inner cylinder 103 can enhance the stability of the inner cylinder 103's position. This reduces the possibility of the inner cylinder 103 swaying or shifting in position due to the interaction and collision of the water flow and the buoyancy in the water over a long period of time. This also reduces the possibility of water leakage through the outer cylinder 102 when the water flows upward between the inner cylinder 103 and the outer cylinder 102 due to the swaying of the outer cylinder 102. This maintains the uniformity of the water flow channel while ensuring stability during and before and after drainage, thus improving drainage efficiency.

[0070] When the water flow, after being bent by the bending plate 122, flows back, it impacts the J-shaped groove 313 and exerts downward pressure on the arc-shaped plate 312. Simultaneously, when the backflow impacts the arc surface at the bottom of the J-shaped groove 313, the impact also synchronously impacts the flexible layer 314. Since the flexible layer 314 is positioned between the inner cylinder 103 and the arc-shaped plate 312 and adheres to the surface of the inner cylinder 103, when the water flow impacts the flexible layer 314 through the J-shaped groove 313, the flexible layer 314 will collide with the surface of the inner cylinder 103 under the impact of the water flow, resulting in a tighter adhesion. By strengthening the contact surface and contact strength between the arc plate 312 and the inner cylinder 103 through the flexible layer 314, it can ensure the sliding strength of the arc plate 312 driving the inner cylinder 103 when the water flow impacts the J-shaped groove 313 and exerts downward pressure on the inner cylinder 103 through the flexible layer 314. This can reduce the situation where the arc plate 312 and the inner cylinder 103 are not tightly fitted and slide against each other due to the collision and buoyancy of the water flow. This can further enhance the fixing strength of the arc plate 312 driving the inner cylinder 103 to slide down when it is subjected to downward pressure, and enhance the stability of the inner cylinder 103 during drainage.

[0071] When the staff manually drains the water after removing the inner cylinder 103, the arc-shaped plates 312 will rotate under the impact of the water flow in the aquaculture tank. When multiple arc-shaped plates 312 are impacted by the water flow, they will rotate relative to each other and form a cone shape inside the grid cylinder 101, presenting a shape like... Figure 10 In the current state, as the water continues to impact the arc-shaped plate 312 and flow into the main body 1, the multiple arc-shaped plates 312, with their inclined arrangement within the grid cylinder 101, guide the water flow at an angle. This reduces the collision and turbulence that occur at the outlet of the main body 1 when the water flows through the outer surface of the grid cylinder 101 into the main body 1. The inclined guidance of the arc-shaped plates 312 reduces water collision and turbulence while ensuring stable outward discharge. Simultaneously, when the water flows into the interior of the inclined J-shaped groove 313, the top water flow area at the discharge point will be guided by the J-shaped groove 313 to flow back again. The backflowing water will also impact the outside of the grid cylinder 101 again, further reducing the adhesion and blockage of impurities at the rectangular through-slots on the grid cylinder 101. This further enhances the stability of the water flow during outward drainage, increases the flow area during drainage, and further shortens the drainage time.
