Description

Technical Field

[0001] This utility model relates to the technical field of siphon sewage discharge equipment for aquaculture, specifically to a siphon sewage discharge device at the bottom of aquaculture ponds. Background Technology

[0002] China has been a culinary powerhouse since ancient times. Especially now, with improved living standards, people are paying more attention to their diet. Many aquatic products, such as fish and shrimp, have become common everyday dishes. Aquatic products are not only delicious but also high in protein and rich in nutrients, making them popular. As the demand for aquatic products continues to rise, the supply of naturally occurring fish and shrimp cannot meet the demand. Therefore, people have begun artificial breeding, with fish farming being the most common. Fish and shrimp are raised in open-type ponds. Their excrement, as well as dust and impurities from the air, fall into the ponds. If the water is not changed regularly, it can lead to disease or death of the fish and shrimp, causing losses for farmers. The potential for incalculable losses is highlighted in patent CN202321318218.2, which discloses a siphon-type sewage discharge device for aquaculture. By installing air bladders, the air bladders, under the mutual compression of two sets of ferrules, can expel air from the first, second, third, and fourth pipes. This eliminates the need for frequent manual water injection, making operation simple and convenient, saving farmers time and effort. However, during the use of this siphon-type sewage discharge device, the negative pressure generated by the contraction of the air bladders is used to draw sewage from the aquaculture pond through the pipes. The sewage then passes through the air bladders before being discharged, causing debris in the sewage to easily adhere to the inner wall of the air bladders, making cleaning quite inconvenient. Therefore, we propose a bottom siphon-type sewage discharge device for aquaculture ponds. Utility Model Content

[0003] To address the problems in the existing technology, this utility model provides a siphon sewage discharge device at the bottom of aquaculture ponds.

[0004] The technical solution adopted by this utility model to solve its technical problem is a bottom siphon sewage discharge device for aquaculture ponds, including a pond body. A secondary pipe for support is connected to the outer periphery of the pond body through a flange, and a ring seat for support is screwed onto the top surface of the secondary pipe. A corrugated rubber seat for limiting is embedded in the inner side of the ring seat, and an L-shaped pipe for guiding flow is snapped into the inner side of the corrugated rubber seat.

[0005] The end of the L-shaped tube away from the ring seat is connected to a cylinder via a flange, and a cylinder seat for support is screwed onto the open end of the top of the cylinder. An electric push rod for adjustment is bolted onto the top surface of the cylinder seat, and a piston seat that is slidably connected to the cylinder seat is bolted onto the power output end of the electric push rod. A one-way air inlet valve is screwed onto the inner side of the cylinder seat near the cylinder, and a one-way air outlet valve for exhaust is screwed onto the open end of the outer periphery of the cylinder seat. A shut-off valve for sealing is connected to the end of the cylinder away from the L-shaped tube via a flange.

[0006] By adopting the above technical solution, during the use of the aquaculture siphon sewage discharge equipment, the secondary pipe is connected to the pool body and the water level in the pool body is the same as the water level in the secondary pipe. Then, it is convenient to screw the ring seat onto the top of the secondary pipe. The L-shaped pipe can be easily inserted and snapped into the corrugated rubber seat inside the ring seat, which makes it easy to adjust the length of the L-shaped pipe inserted into the secondary pipe, thus facilitating subsequent siphon sewage discharge treatment and making adjustment more convenient.

[0007] During siphon drainage, the electric push rod continuously reciprocates, driving the piston seat inside the cylinder to slide back and forth. The one-way air inlet valve allows air to smoothly enter the cylinder without backflow, and the one-way air outlet valve allows air to exit the cylinder without backflow. The piston seat then moves back and forth, continuously drawing air from the cylinder and creating negative pressure. This facilitates the extraction of water from the tank through the L-shaped pipe into the cylinder. Opening the inclined shut-off valve on the outside of the cylinder allows the water inside to be discharged. Thus, water is automatically pumped and discharged under siphon action, and sewage from the tank does not enter the cylinder, preventing any impact on the operation of the cylinder's internal structure. This ensures more stable operation of the aquaculture siphon drainage equipment.

[0008] Specifically, the end of the shut-off valve away from the cylinder is connected to a bend seat for flow guidance via a flange, and the end of the bend seat away from the shut-off valve is screwed onto a swivel seat for support. A flexible hose body that fits into the bend seat is snapped into the inner side of the swivel seat.

[0009] By adopting the above technical solution, the sewage discharged from the cylinder can easily enter the bend seat and flow into the hose body, making it convenient to discharge the pumped sewage to the designated location. The swivel seat and bend seat are easy to disassemble and assemble, facilitating the replacement of the hose body.

[0010] Specifically, the outer circumference of the ring seat is integrally constructed with protrusions for limiting the position, and there are multiple sets of protrusions.

[0011] By adopting the above technical solution, the protruding rod makes it easier to assemble and disassemble the ring seat.

[0012] Specifically, a shut-off valve is installed on the inner side of the cylinder seat.

[0013] By adopting the above technical solution, the shut-off valve inside the cylinder seat can easily block the channel between the cylinder seat and the cylinder body. After generating the siphon sewage discharge effect, it can block the cylinder seat, which helps to reduce the situation of water entering the cylinder seat.

[0014] Specifically, the outer periphery of the cylinder is fitted with an observation window for sealing via bolts.

[0015] By adopting the above technical solution, the observation windows on the outer periphery of the cylinder allow personnel to easily observe the amount of water pre-stored inside the cylinder, and facilitate the control of the siphon effect.

[0016] Specifically, the electric push rod is equipped with a controller that is electrically connected to the electric push rod.

[0017] By adopting the above technical solution, the controller can easily control the operation of the electric linear actuator and make it convenient to use.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The technical solution of this application, through the design of a secondary pipe, ring seat, corrugated rubber seat and L-shaped pipe, allows the secondary pipe to be connected to the pool body during the use of the aquaculture siphon sewage discharge equipment, and the water level in the pool body is the same as the water level in the secondary pipe. Then, the ring seat can be easily screwed into the top of the secondary pipe, and the L-shaped pipe can be easily inserted and snapped into the corrugated rubber seat inside the ring seat, which facilitates the adjustment of the length of the L-shaped pipe inserted into the secondary pipe, thereby facilitating subsequent siphon sewage discharge treatment and making adjustment more convenient.

[0020] 2. The technical solution of this application, through the design of a cylinder, cylinder base, one-way air inlet valve, one-way air outlet valve, electric push rod, piston seat, and shut-off valve, enables the electric push rod to continuously reciprocate during siphon sewage discharge, driving the piston seat inside the cylinder base to reciprocate and slide. The one-way air inlet valve allows air inside the cylinder to smoothly enter the cylinder base without backflow, and the one-way air outlet valve allows air inside the cylinder base to be discharged without backflow. Subsequently, the piston seat moves back and forth, continuously drawing air from inside the cylinder and creating negative pressure, thus facilitating the extraction of water from the pool through the L-shaped pipe and into the cylinder. Then, opening the inclined shut-off valve on the outside of the cylinder allows the water inside the cylinder to be discharged. Thus, water is automatically pumped and discharged under siphon action, and sewage from inside the pool does not enter the cylinder base, thereby not affecting the operation of the internal structure of the cylinder base, making the aquaculture siphon sewage discharge equipment more stable in use.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] Please see Figure 1-3 This utility model provides a technical solution: a bottom siphon sewage discharge device for aquaculture ponds, including a pond body 1. A secondary pipe 2 for support is connected to the outer periphery of the pond body 1 via a flange. A ring seat 3 for support is screwed onto the top surface of the secondary pipe 2. A corrugated rubber seat 4 for limiting is embedded in the inner side of the ring seat 3. An L-shaped pipe 5 for guiding flow is clamped onto the inner side of the corrugated rubber seat 4. A cylinder 6 is connected to the end of the L-shaped pipe 5 away from the ring seat 3 via a flange. A cylinder seat 7 for support is screwed onto the open end of the top of the cylinder 6. An electric push rod 10 for adjustment is bolted onto the top surface of the cylinder seat 7. A piston seat 11 that slides with the cylinder seat 7 is bolted onto the power output end of the electric push rod 10. A one-way air inlet valve 8 is screwed onto the inner side of the cylinder seat 7 near the cylinder 6. A one-way air outlet valve 9 for exhaust is screwed onto the open end of the outer periphery of the cylinder seat 7. A shut-off valve 12 for sealing is connected to the end of the cylinder 6 away from the L-shaped pipe 5 via a flange.

[0028] When using the aquaculture siphon sewage discharge equipment, the secondary pipe 2 is connected to the pool body 1 and the water level in the pool body 1 is the same as the water level in the secondary pipe 2. Then, the ring seat 3 can be screwed into the top of the secondary pipe 2. The L-shaped pipe 5 can be easily inserted and snapped into the corrugated rubber seat 4 inside the ring seat 3, which makes it easy to adjust the length of the L-shaped pipe 5 inserted into the secondary pipe 2, thus facilitating subsequent siphon sewage discharge treatment and making adjustment more convenient.

[0029] During siphon drainage, the electric push rod 10 continuously reciprocates, driving the piston seat 11 inside the cylinder seat 7 to slide back and forth. The one-way air inlet valve 8 allows air inside the cylinder 6 to smoothly enter the cylinder seat 7 without backflow, and the one-way air outlet valve 9 allows air inside the cylinder seat 7 to be discharged without backflow. Subsequently, the piston seat 11 reciprocates and continuously draws air from inside the cylinder 6, creating negative pressure. This facilitates the extraction of water from the pool 1 through the L-shaped pipe 5 into the cylinder 6. Then, opening the inclined shut-off valve 12 on the outside of the cylinder 6 allows the water inside the cylinder 6 to be discharged. Thus, water is automatically pumped and discharged under siphon action, and the sewage inside the pool 1 does not enter the cylinder seat 7, thereby not affecting the operation of the internal structure of the cylinder seat 7. This allows the aquaculture siphon drainage equipment to be used more stably.

[0030] like Figure 1 As shown, the end of the shut-off valve 12 away from the cylinder 6 is connected to a bend seat 13 for guiding flow via a flange, and the end of the bend seat 13 away from the shut-off valve 12 is screwed onto a swivel seat 14 for support. A flexible hose body 15 that fits into the bend seat 13 is snapped into the inner side of the swivel seat 14.

[0031] During use, the sewage discharged from the cylinder 6 can easily enter the bend seat 13 and flow into the hose body 15, making it easy to discharge the extracted sewage to the designated location. The swivel seat 14 and the bend seat 13 are easy to disassemble and assemble, making it convenient to replace the hose body 15.

[0032] like Figure 1 and Figure 2 As shown, the outer circumference of the ring seat 3 has integrally constructed protrusions 18 for limiting the position, and there are multiple sets of protrusions 18.

[0033] When in use, the protruding rod 18 makes it easier to assemble and disassemble the ring seat 3.

[0034] like Figure 1 and Figure 3 As shown, a shut-off valve 19 is installed inside the cylinder seat 7.

[0035] During use, the shut-off valve 19 inside the cylinder seat 7 can conveniently block the channel between the cylinder seat 7 and the cylinder 6. After the siphon sewage discharge effect is generated, the cylinder seat 7 can be blocked, which can reduce the situation of water entering the cylinder seat 7.

[0036] like Figure 1 As shown, the outer circumferential opening of the cylinder 6 is fitted with an observation window 16 for sealing via bolts.

[0037] During use, the observation window 16 on the outer periphery of the cylinder 6 allows personnel to observe the amount of water pre-stored inside the cylinder 6, facilitating the control of the siphon effect.

[0038] like Figure 1 As shown, a controller 17 electrically connected to the electric actuator 10 is assembled on the outer periphery of the electric actuator 10.

[0039] When in use, the controller 17 facilitates the operation of the electric push rod 10, making it convenient to use.

[0040] The working principle and usage process of this utility model are as follows: First, the secondary pipe 2 and the pool body 1 are securely connected by a flange, achieving communication between the two. Due to the principle of communicating vessels, the water levels in the pool body 1 and the secondary pipe 2 will remain highly consistent. Next, the operator screws the ring seat 3 onto the top of the secondary pipe 2. The protruding rod 18 on the outer periphery of the ring seat 3 provides a convenient point of force application for the operator, making the installation process easier. During installation, the operator only needs to hold the protruding rod 18 and rotate the ring seat 3 clockwise to secure it tightly to the secondary pipe 2, ensuring the sealing of the connection and preventing leakage. Subsequently, one end of the L-shaped pipe 5 is connected to the ring seat 3. The internal corrugated rubber seats 4 interlock and snap together. The corrugated rubber seats 4 not only have good flexibility and can tightly fit the outer wall of the L-shaped tube 5 to play a sealing role, but also provide a stable limit for the L-shaped tube 5, so that it will not shake or shift during operation. The operator can flexibly adjust the length of the L-shaped tube 5 inserted into the secondary tube 2 according to the actual sewage discharge needs. When it is necessary to enhance the siphon effect, the L-shaped tube 5 can be inserted into the secondary tube 2 appropriately; if only light sewage discharge is required, the insertion depth of the L-shaped tube 5 can be shortened. This adjustable design greatly improves the applicability of the device and can meet the sewage discharge needs of different breeding scenarios.

[0041] When the device is ready, the operator starts the electric push rod 10 via controller 17. The forward and reverse rotation of the electric push rod 10 controls the movement direction of the piston seat 11. When the motor inside the electric push rod 10 rotates forward, the lead screw rotates clockwise, and the nut drives the piston seat 11 to move away from the cylinder 6. At this time, the space inside the cylinder seat 7 increases and the pressure decreases. When the motor inside the electric push rod 10 rotates in reverse, the lead screw rotates counterclockwise, and the nut drives the piston seat 11 to move closer to the cylinder 6. The space inside the cylinder seat 7 decreases and the pressure increases. Through this switching of forward and reverse rotation, the piston seat 11 achieves reciprocating sliding displacement within the cylinder seat 7, providing power support for the subsequent siphon sewage discharge process. When the piston seat 11 moves away from the cylinder 6, the space inside the cylinder seat 7 gradually increases, and the pressure decreases accordingly, forming a relatively low-pressure area. At this time, the one-way air inlet valve 8 opens quickly, allowing the relatively high-pressure air inside the cylinder 6 to flow smoothly into the cylinder seat 7, while the one-way air outlet valve 9 closes tightly to prevent external air from flowing back into the cylinder 6 and cylinder seat 7. Conversely, when... As the piston seat 11 moves closer to the cylinder 6, the space inside the cylinder seat 7 decreases, the pressure increases, and it becomes a relatively high-pressure area. At this time, the one-way exhaust valve 9 immediately opens, venting the high-pressure air inside the cylinder seat 7 and restoring the pressure inside the cylinder seat 7 to a normal level. Meanwhile, the one-way intake valve 8 closes to prevent the exhausted air from re-entering the cylinder 6. Furthermore, the valve disc of the one-way intake valve 8 closes in the reverse direction under the action of the pressure difference, effectively preventing air backflow and ensuring the unidirectional flow of gas. Through this reciprocating motion, the piston seat... 11. The air inside the cylinder 6 is continuously extracted, causing the pressure inside the cylinder 6 to continuously decrease and gradually generate negative pressure. When the pressure inside the cylinder 6 is lower than the water pressure inside the pool 1, the water inside the pool 1 is "sucked" into the L-shaped pipe 5 under the action of the water pressure difference. One end of the L-shaped pipe 5 is inserted into the secondary pipe 2 and connected to the water in the pool 1, while the other end is connected to the cylinder 6. Due to the special shape and connection method of the L-shaped pipe 5, the water in the pool 1 can smoothly enter the L-shaped pipe 5 and flow along the pipe of the L-shaped pipe 5 to the cylinder 6.

[0042] In this process, the water flow is continuous and stable. First, water enters the inlet of L-shaped pipe 5 from pool 1. Since the inside of L-shaped pipe 5 is connected to cylinder 6 and cylinder 6 is under negative pressure, the water overcomes the resistance of the pipe under the pressure difference and flows upward along the curved part of L-shaped pipe 5. When the water reaches the top of L-shaped pipe 5, due to inertia and the continuous effect of pressure difference, the water continues to flow downward and enters the inside of cylinder 6. As water continues to flow into cylinder 6, the water level inside cylinder 6 gradually rises, forming a dynamic siphon process. In this process, the water flow speed and flow rate are affected by a variety of factors, such as the degree of negative pressure inside cylinder 6, the diameter of L-shaped pipe 5, and the height difference between pool 1 and cylinder 6. By reasonably adjusting these factors, the siphon effect can be optimized and the sewage discharge efficiency can be improved.

[0043] When the cylinder 6 is filled with sewage and the expected discharge volume is reached, the operator only needs to gently operate the controller 17 to close the electric push rod 10 and stop the reciprocating motion of the piston seat 11. At this time, the siphon process inside the cylinder 6 temporarily stops, and the water is in a relatively static state. Next, the operator opens the shut-off valve 12. With the opening of the shut-off valve 12, the sewage inside the cylinder 6 quickly flows into the bend seat 13 under the combined action of gravity and siphon residual pressure. At this time, the flow on both sides inside the cylinder 6 is sealed by water, and the shut-off valve 19 inside the cylinder seat 7 is blocked, making the remaining space inside the cylinder 6 a vacuum. When the water inside the cylinder 6 flows out from the bend seat 13, it can continuously and automatically draw sewage from the tank 1 through the L-shaped pipe 5 under the negative pressure inside the cylinder 6. Thus, the sewage can be continuously and automatically drawn in and discharged under the siphon action. At the same time, the bend seat 13 is designed in a curved shape, which can guide the sewage to change its flow direction smoothly, making it flow towards the hose body 15. The smooth inner wall of the bend seat 13 reduces the resistance to sewage flow, allowing sewage to pass through quickly and improving sewage discharge efficiency. After the sewage flows from the bend seat 13 into the hose body 15, the hose body 15 has good flexibility and corrosion resistance, and can adapt to different discharge environments and terrain conditions. It can be bent and arranged according to actual needs to transport sewage to the designated discharge location. Whether discharged to sewage treatment ponds or other treatment areas far away from aquaculture ponds, the hose body 15 can stably complete the task. At the same time, operators can easily install and remove the hose body 15 by simply rotating the rotating seat 14. When the hose body 15 needs to be replaced, the operator only needs to rotate the rotating seat 14 counterclockwise to remove the old hose body 15, then install the new hose body 15 in place, and then rotate the rotating seat 14 clockwise to fix it firmly. This convenient connection method greatly improves the maintenance efficiency of the equipment and reduces the time and cost waste caused by equipment maintenance.

[0044] After the siphon discharge effect is achieved, the operator can close the shut-off valve 19 via controller 17 or manual operation to cut off the channel between the cylinder seat 7 and the cylinder 6, thereby reducing the possibility of water entering the cylinder seat 7 and ensuring the stability and reliability of the device. The observation window 16, bolted to the outer opening of the cylinder 6, allows the operator to observe the pre-stored water level inside the cylinder 6 in real time. The operator can visually see the water level inside the cylinder 6 through the observation window 16 to determine whether the siphon effect has reached the expected level. If the pre-stored water level inside the cylinder 6 is insufficient, it may mean that there is a problem with the siphon process, which needs to be checked and adjusted in time. When the pre-stored water level reaches a certain level, the operator can prepare to open the shut-off valve 12 to discharge the sewage. The presence of the observation window 16 allows the operator to better control the siphon effect and improves the accuracy and safety of the sewage discharge operation.
