[0027] The present utility model will be described in detail below in conjunction with the accompanying drawings.

[0028] Please refer to Figure 1 , this embodiment provides a drainage facility for aquaculture, which is installed in a breeding pond. The breeding pond includes a breeding pool for providing aquaculture space and a drainage pool for water replacement. The aforementioned drainage facility includes a drain pipe 1 for connecting the breeding pool and the drainage pool, a plug-and-play pipe 2 vertically installed in the drainage pool, a drainage control structure, a float type water level switch 7 located in the breeding pool, a solid waste discharge structure, and an air pipe assembly 13.

[0029] A sewage collection port is penetrated and opened at the center position of the bottom of the breeding pool. One end of the drain pipe 1 is fixedly penetrated and installed at the bottom of the breeding pool through the sewage collection port, and the other corresponding end of the drain pipe 1 extends into the drainage pool. The drainage control structure includes a tee pipe 3 fixedly connected between the drain pipe 1 and the plug-and-play pipe 2, a pneumatic butterfly valve 4 fixedly installed at the drainage port of the tee pipe 3, a control box 5, a solenoid valve 6 fixedly installed on the control box 5, and an air compressor 8.

[0030] An electric wire is fixedly connected between the float type water level switch 7 and the control box 5. According to the set depth of the breeding requirements, during drainage, when the water level is lower than the set water level, the float type water level switch 7 of this embodiment is triggered, causing the control box 5 to close the solenoid valve 6, and then closing the pneumatic butterfly valve 4 to automatically stop drainage. In view of the situation that the valves used in traditional drainage are often splashed or soaked by water, in this embodiment, the structure of using an air compressor 8 to compress air to drive the pneumatic butterfly valve 4 is adopted to open / close the drainage function, replacing the original plug-and-play pipe, manual valve or electric valve. It effectively separates water and electricity, avoids equipment leakage and burnout or injury to people, and at the same time realizes the automatic control effect of the water body discharge in the breeding pool.

[0031] The control box 5 of this embodiment is installed at a designated fixed point near the aquaculture farm. It should be noted that a leakage switch, a wireless controller, a DC power supply, and an intermediate relay are installed in the control box 5 (not shown in the following component diagrams). The leakage switch provides overload and short-circuit protection. The wireless controller is used to achieve remote cooperation with the mobile phone APP, so as to monitor the working state in real time, set the drainage time and the time for discharging solid waste of each water tank, and receive power-off, water level alarm, and various operation information. The power supply is based on the DC power supply, and the intermediate relay realizes the linkage between various functions to ensure the coordinated cooperation of each functional area of the entire drainage facility. The above-mentioned components are all common configurations and are mature existing technologies, so they will not be elaborated here.

[0032] Please refer to Figures 2-3 , the solid waste discharge structure includes a riser pipe 9 fixedly inserted at the sewage collection port, a hole opened near the sewage collection port of the riser pipe 9, a PVC grille pipe 10 sleeved on the riser pipe 9 facing the hole, and a cylinder 11 for driving the PVC grille pipe 10. In this embodiment, a PVC pipe with a nominal diameter of 110 mm is used as the riser pipe 9, and a PVC grille pipe 10 with a nominal diameter of 160 mm is used for illustration.

[0033] The riser pipe 9 is communicated with the drain pipe 1. The hole is used to provide a passage for the solid waste to pass through, and the number of holes is two groups. The two groups of holes are distributed and opened at the corresponding two side wall positions of the riser pipe 9. In this embodiment, when it is necessary to discharge solid waste, the cylinder 11 drives the PVC grille pipe 10 to move vertically upward to expose the hole. On the contrary, when the cylinder 11 drives the PVC grille pipe 10 to move vertically downward and cover the hole, the solid waste is intercepted, and the water body can be normally discharged. At the same time, through the PVC grille pipe 10 as a partition, to a certain extent, it can avoid the discharge of small fish and shrimps during drainage, thus avoiding breeding losses.

[0034] The cylinder 11 is fixedly installed at the top pipe orifice of the riser pipe 9, and a connection assembly 12 is installed between the cylinder 11 and the PVC grille pipe 10. The connection assembly 12 includes a guide groove 121 penetratingly opened on the pipe wall of the riser pipe 9, and a support rod 122 fixedly connected between the piston rod of the cylinder 11 and the PVC grille pipe 10. The support rod 122 is adapted to the guide groove 121, and the support rod 122 is vertically penetrated through the riser pipe 9 through the guide groove 121. In this embodiment, the assembly between the PVC grille pipe 10 and the cylinder 11 is realized based on the connection assembly 12, that is, the support rod 122 fixes the PVC grille pipe 10 and the piston rod of the cylinder 11. When the piston rod of the cylinder 11 moves vertically, the support rod 122 drives the PVC grille pipe 10 to move. At this time, the guide groove 121 provides a moving space for the support rod 122.

[0035] The trachea assembly 13 is composed of trachea I, trachea II, and trachea III. Among them, trachea I is used to connect the pneumatic butterfly valve 4 and the solenoid valve 6, trachea II is used to connect the cylinder 11 and the solenoid valve 6, and trachea III is used to connect the solenoid valve 6 and the air compressor 8.

[0036] It should be noted that for the drainage facilities in this embodiment, in actual application, the drainage and solid waste discharge times can be set by combining with a mobile phone APP. For example, the starting point of the solid waste discharge time with fewer times is synchronized with the starting point of the drainage time. In this way, when the pneumatic butterfly valve 4 is opened, the cylinder 11 acts simultaneously to open the PVC grille pipe 10, and the wastewater and solid wastes such as shrimp shells are discharged simultaneously. When the set time is reached, the cylinder 11 closes the PVC grille pipe 10, and the shrimp shell discharge operation is completed, while the drainage can continue.

[0037] This automatic drainage control system adopts a design combining pneumatic control and solenoid valves, enabling synchronous control of drainage and waste discharge through preset time. For example, when the pneumatic butterfly valve is opened, the cylinder controls the opening of the PVC grille pipe, thereby realizing the simultaneous discharge of wastewater and solid wastes, achieving synchronization of drainage and solid waste discharge. When the set time arrives, the cylinder closes the PVC grille pipe, completing the discharge of solid wastes, while the drainage operation can continue. The design concept of the entire system takes into account the requirements of drainage and solid waste discharge in the aquaculture environment and combines this requirement with automated control, greatly improving the efficiency of aquaculture management. The corrosion resistance and safety performance of the equipment are also emphasized in the design to ensure the reliable operation of the facilities in the aquaculture environment. In summary, the design concept of this automatic drainage control system focuses on practicality, efficiency, and safety, providing an efficient and reliable management solution for aquaculture.

[0038] In summary, compared with the current drainage mode of aquaculture ponds, the drainage facilities of this embodiment have the following advantages: The drainage facilities of this embodiment achieve automated control, improve the efficiency of aquaculture management, and effectively save labor and time costs. At the same time, the discharge of solid wastes such as shrimp shells, feed residues, and feces is convenient. In addition, the corrosion resistance and safety performance of the facilities can also meet the requirements of aquaculture, having good popularization and application value. The drainage facilities of this embodiment are suitable for drainage use in various types of aquaculture ponds such as high-level ponds, cement ponds, membrane bag ponds, and PP ponds, and have excellent popularization and application prospects.

Those skilled in the art can also choose other nouns to describe the names of the various components of this utility model.
