Description

Technical Field

[0001] This utility model relates to the field of facility fishery technology, and in particular to a drainage device for elevated aquaculture ponds. Background Technology

[0002] To address the growing demand for high-quality aquatic products, my country has continuously implemented land-based aquaculture infrastructure projects to increase production and balance supply and demand in the aquatic product market. Factory-style recirculating aquaculture systems (RAS) are a modern facility-based aquaculture model. Utilizing technologies such as filtration, purification, disinfection, and biochemical treatment, the water in the aquaculture ponds is treated to maintain stable water quality, allowing for water recycling and significant water conservation. Through scientific feeding and management, the yield per unit volume of water can be effectively increased. During the aquaculture process, not only is water recycling necessary, but the aquaculture water is also periodically discharged from the recirculating system to reduce the impact of substances such as nitrates on the farmed products. This requires the use of a pond drainage system to safely and reliably discharge the aquaculture water.

[0003] In recent years, my country's plains and coastal areas have frequently experienced extreme weather events such as heavy rainfall in summer, which can lead to severe flooding and seawater intrusion, affecting aquaculture safety. To mitigate the impact of these disasters, aquaculture ponds are typically raised to create elevated aquaculture ponds. This is achieved by piling and compacting earth to build a dam, filling it with aquaculture water to create a water level higher than the surrounding ground. This dam isolates the aquaculture water in case of flooding or seawater intrusion, preventing the loss of farmed products. To ensure the dam's compaction and seepage resistance, the dam should not be constructed before the drainage system is installed. Instead, the drainage system should be placed first, followed by earth piling and compaction. This places high demands on the structural performance of the drainage system. However, most current methods, such as brick-built drainage wells, plastic drainage wells, and pre-buried drainage pipes, lack the structural reliability required for dam compaction construction, and most existing drainage systems lack reliable anti-escape mechanisms for aquaculture drainage.

[0004] Therefore, a new type of elevated aquaculture pond drainage device is needed to solve the difficulties existing in the current project. Utility Model Content

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0031] Please see Figures 1-4 This utility model provides a drainage device for elevated aquaculture ponds, which is buried in the dam body 015 of elevated aquaculture ponds. It includes a reinforced concrete retaining structure, a connecting pipe assembly, a drainage pipe 012, a water level balancing pipe 011, and an escape prevention net 006.

[0032] The reinforced concrete enclosure structure serves as the main structure of the drainage system, comprising a drainage chamber 014 and an escape-prevention chamber 013. The drainage chamber 014 and the escape-prevention chamber 013 are connected by a connecting pipe assembly, one end of which extends to the bottom of the drainage chamber 014. A drainage pipe 012 is embedded in the bottom of the side wall of the drainage chamber 014. A water level balancing pipe 011 is installed in the drainage chamber 014 and is detachably connected to the connecting pipe assembly. An escape-prevention net 006 is installed in the escape-prevention chamber 013 near the inlet of the drainage system. Aquaculture water from the pond enters the escape-prevention chamber 013 through the escape-prevention net 006. The escape-prevention net 006 effectively prevents aquaculture products from entering the interior of the reinforced concrete enclosure structure from the pond, thus effectively preventing the escape of aquaculture products.

[0033] The water level balancing pipe 011 is a hollow tubular structure. When there is no need to discharge aquaculture water, the water level balancing pipe 011 is connected to the connecting pipe assembly. After the aquaculture water enters the escape-prevention chamber 013, it flows into the water level balancing pipe 011 through the connecting pipe assembly. At this time, the liquid level in the water level balancing pipe 011 is level with the aquaculture water level in the aquaculture pond. Figure 3 As shown by water level trace A in the middle of the aquaculture pond, the aquaculture water cannot be discharged from the aquaculture pond. In the event that the aquaculture water needs to be discharged, the water level balancing pipe 011 can be removed from the connecting pipe assembly, so that the aquaculture water in the escape prevention chamber 013 can be introduced into the drainage chamber 014 through the connecting pipe assembly, and then discharged from the aquaculture pond through the drainage pipe 012.

[0034] It should be noted that after draining a certain amount of aquaculture water as needed, the water level balance pipe 011 can be installed on the connecting pipe assembly to stop the drainage.

[0035] Specifically, the reinforced concrete enclosure structure includes a base slab 001, a back slab 002, side slabs 004, and a partition 003. All four slabs are reinforced concrete and can be integrally cast into a single reinforced concrete structure. The side slabs 004 are located on opposite sides of the base slab 001, and the back slab 002 is located on the side of the base slab 001 furthest from the drainage inlet, and is connected to both side slabs 004. The base slab 001, back slab 002, side slabs 004, and escape-prevention net 006 enclose a cavity. The partition 003 is located within the cavity, dividing it into a drainage chamber 014 and an escape-prevention chamber 013.

[0036] The back plate 002 and side plate 004 are of equal height and both are greater than the height of the partition 003. When the water level in the aquaculture pond suddenly increases, the liquid level in the water level balancing pipe 011 remains level with the aquaculture water level in the aquaculture pond. The suddenly increased aquaculture water overflows from the top of the partition 003 into the drainage well chamber 014, and then is discharged from the high-level aquaculture pond through the drainage pipe 012. This design can effectively prevent the disorderly leakage of aquaculture water caused by a sudden increase in the water level in the aquaculture pond.

[0037] See Figures 2-4 The connecting pipe assembly includes a connecting pipe 008 and a connecting sleeve 010. The connecting pipe 008 is embedded in the bottom of the partition 003, and its extended end extends to the bottom of the drainage well chamber 014. The connecting sleeve 010 is fitted onto the extended end of the connecting pipe 008, and the water level balancing pipe 011 is connected to the connecting pipe 008 through the connecting sleeve 010. Specifically, the extended end of the connecting pipe 008 has an upward-curved section that bends toward the top of the drainage well chamber 014, and the connecting sleeve 010 is fitted onto the upward-curved section of the connecting pipe 008.

[0038] Furthermore, the reinforced concrete enclosure structure also includes a concrete enclosure 009, which is located at the bottom of the drainage chamber 014. The portion of the connecting pipe 008 extending into the drainage chamber 014 and the connecting sleeve 010 are embedded in the concrete enclosure 009. The portion of the connecting sleeve 010 used to connect with the water level balancing pipe 011 extends out of the surface of the concrete enclosure 009. The concrete enclosure 009 is used to protect and fix the connecting pipe 008 and the connecting sleeve 010.

[0039] The drain pipe 012 is embedded at the bottom of the back plate 002, and the concrete enclosure 009 is located on the side of the drain pipe 012 near the bottom plate 001. Preferably, the drain pipe 012 is located above the upper surface of the concrete enclosure 009, so that the aquaculture water can be smoothly discharged from the drain pipe 012.

[0040] See Figure 3 and Figure 4 When the drainage device is embedded in the elevated aquaculture pond dam 015, the top of the drainage device can be higher than the top of the dam 015a, and the bottom of the drainage device can be lower than the pond bottom elevation C. The inner and outer sides of the elevated aquaculture pond dam 015 are sloped at a certain angle, such as... Figure 4 The dam slope trace line D is shown in the diagram.

[0041] When the water level balancing pipe 011 is connected to the connecting pipe assembly, the top of the water level balancing pipe 011 is higher than the aquaculture water level B of the aquaculture pond, and the top of the water level balancing pipe 011 is higher than the top of the partition 003. The liquid level in the water level balancing pipe 011 is flush with the aquaculture water level in the aquaculture pond. This ensures that when drainage is not required, the aquaculture water in the water level balancing pipe 011 will not overflow into the drainage well chamber 014 due to the liquid level difference.

[0042] See Figure 1 , Figure 2 and Figure 4 Limiting grooves 007 are constructed on the upper surface of the base plate 001 and the inner walls of the two side plates 004. An escape-proof net 006 is inserted into the limiting grooves 007, which are used to fix the escape-proof net 006. When the escape-proof net 006 is inserted into the limiting grooves 007, the top of the escape-proof net 006 is flush with the top of the side plates 004, thus effectively preventing aquaculture products from entering the escape-proof chamber 013 from the aquaculture pond.

[0043] Among them, the escape-proof net 006 is mainly used to intercept aquaculture products and prevent them from escaping when the aquaculture pond is drained. The escape-proof net 006 consists of a net fabric and a fixing frame. The net fabric is made of polyethylene fishing net line and conforms to the aquaculture industry standard SC 141-85. Its mesh size is determined by the aquaculture requirements. The fixing frame is made of polypropylene (PP) material and is mainly used to fix the net fabric of the escape-proof net 006, making it easy for the escape-proof net 006 to be inserted into the limiting groove 007.

[0044] The number of anti-escape nets 006 can be one, two, or more, depending on actual needs, and there is no restriction here.

[0045] In one embodiment, the reinforced concrete enclosure structure further includes a cushion layer 005, on which a base plate 001 is placed. The cushion layer 005 is mainly used for sealing, leveling, and protecting the base of the drainage device for elevated aquaculture ponds, and suitable concrete materials can be selected according to the corrosive environment.

[0046] Specifically, the bottom plate 001 should be designed with double-layer bidirectional reinforcement according to the boundary constraints and the foundation reaction force, and should be configured as a bending member. The back plate 002 and side plate 004 should be designed with double-layer bidirectional reinforcement according to the boundary constraints and the compaction load during dam construction and the water and soil pressure during daily use. The partition plate 003 should be designed with double-layer bidirectional reinforcement according to the boundary constraints and the water pressure in the aquaculture pond during use. The limiting groove 007 can be regarded as a local thickened area of ​​the side plate 004, and the structure can be configured with longitudinal reinforcement and tie bars.

[0047] The above designs all comply with national standards GB 55008-2021 and GB / T 50010-2010, and the strength grades of concrete and steel reinforcement materials are determined by the design based on actual conditions.

[0048] Among them, the connecting pipe 008, connecting sleeve 010, water level balancing pipe 011, and external drainage pipe 012 are all made of rigid polyvinyl chloride (PVC-U) pipe, which complies with the national standard GB / T 10002.1-2023. The pipe diameter of the above components is determined by design according to the actual situation.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
