Abstract
Description
Technical fields:
[0001] This utility model relates to the field of aquaculture technology, and in particular to an automatic sewage discharge system for aquaculture ponds. Background technology:
[0002] Because fish and shrimp farming ponds contain fish and shrimp excrement and uneaten feed, the accumulation of these substances can affect water quality and cause diseases in the fish and shrimp. To maintain water quality and prevent diseases caused by the accumulation of pollutants such as excrement and uneaten feed, the ponds need to be emptied multiple times a day.
[0003] In existing technologies, most sewage discharge systems still rely on manual operation. These systems include aquaculture ponds, a drain outlet at the bottom of the pond, a sealing plug at the drain outlet, and a water inlet pipe for adding water to the pond. When sewage needs to be discharged, the sealing plug at the drain outlet at the bottom of the pond is manually removed. After a certain period of time, the sealing plug is manually replaced to block the drain outlet, and water is added back to the pond through the water inlet pipe. This operation is cumbersome, time-consuming, and labor-intensive, resulting in high workload for aquaculture workers. There is an urgent need for an automatic sewage discharge system that can replace the manual method for automatically discharging sewage from aquaculture ponds. Utility model content:
[0004] The purpose of this invention is to provide an automatic sewage discharge system for aquaculture ponds that addresses the shortcomings of existing technologies. This system can replace purely manual methods to achieve automatic sewage discharge, is very easy to operate, saves time and effort, greatly reduces the labor intensity of aquaculture workers, and is better suited for sewage discharge in aquaculture ponds.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is: an automatic sewage discharge system for aquaculture ponds, including an aquaculture pond, a drain outlet located at the bottom of the aquaculture pond, a water inlet pipe for adding water to the aquaculture pond, and a drain pipe. The bottom end of the drain pipe is connected to the drain outlet, and the drain pipe and the aquaculture pond form a communicating vessel structure. The drain pipe is provided with an overflow outlet and a forced discharge outlet. The height of the forced discharge outlet is lower than that of the overflow outlet. An automatic valve device for controlling the forced discharge outlet to connect with or close to the outside is provided at the position of the forced discharge outlet.
[0006] A further improvement to the above scheme is that the automatic valve device includes a control component, a sealing airbag located at the forced discharge port, an inflation component for inflating the sealing airbag, and a deflation component for deflating the sealing airbag.
[0007] A further improvement to the above scheme is that the inflation assembly includes an inflation pump, an inflation pipe, and a one-way airflow valve installed on the inflation pipe. The output end of the inflation pump is connected to the sealing airbag through the inflation pipe, and the control component is electrically connected to the inflation pump.
[0008] A further improvement to the above scheme is that the deflation assembly includes a deflation port connected to the inflation pipe and a deflation valve located at the deflation port; when the deflation valve is in the open state, the inflation pipe is connected to the external atmospheric pressure through the deflation port.
[0009] A further improvement to the above solution is that the venting valve is a manual valve or a solenoid valve, and the control component is electrically connected to the solenoid valve.
[0010] A further improvement to the above scheme is that the automatic valve device also includes a pressure gauge for detecting the pressure inside the inflation pipe.
[0011] A further improvement to the above solution is that the automatic valve device further includes an airbag mounting assembly for fixing the sealing airbag.
[0012] A further improvement to the above solution is that the occlusion airbag is made of rubber material.
[0013] A further improvement to the above solution is that the automatic valve device further includes a display module and / or a communication module, and the control component is electrically connected to the display module and the communication module respectively.
[0014] A further improvement to the above scheme is that the drainage pipe is arranged vertically, and the drainage pipe and the aquaculture pond form a U-shaped communicating vessel structure.
[0015] The beneficial effects of this utility model are as follows: This utility model provides an automatic sewage discharge system for aquaculture ponds, including an aquaculture pond, a drain outlet set at the bottom of the aquaculture pond, a water inlet pipe for adding water to the aquaculture pond, and a drain pipe. The bottom end of the drain pipe is connected to the drain outlet, and the drain pipe and the aquaculture pond form a communicating vessel structure. The drain pipe is provided with an overflow outlet and a forced discharge outlet. The height of the forced discharge outlet is lower than the height of the overflow outlet. An automatic valve device for controlling the connection or closure of the forced discharge outlet with the outside is provided at the position of the forced discharge outlet.
[0016] Compared to existing traditional manual sewage discharge systems, this invention, when used for aquaculture, continuously adds water to the pond via a water inlet pipe. Because the drain pipe and the pond form a communicating vessel structure, when the forced discharge port on the drain pipe is closed, the water in the pond slowly flows out from the overflow port under the pressure difference, maintaining a flowing state and effectively discharging sewage. This better preserves the water quality and prevents it from deteriorating too quickly, thus avoiding the need for frequent forced discharges. When connected, the water in the aquaculture pond will rapidly and in large quantities leak out from the strong discharge port of the drain pipe under the action of pressure difference. Because the liquid level difference between the strong discharge port and the aquaculture pond is large, when the strong discharge port is connected, the aquatic excrement and uneaten feed deposited at the bottom of the aquaculture pond can be discharged more fully. After the strong discharge port has been used for a certain period of time, the strong discharge port is closed, and the automatic discharge of the aquaculture pond is repeated. This utility model can replace the purely manual method to achieve automatic discharge. It is very simple to operate, saves time and labor, and can greatly reduce the labor intensity of aquaculture workers. It is better suited for the discharge of aquaculture ponds.

[0020] The present invention will be further described below with reference to the accompanying drawings, such as... Figure 1-2As shown, this utility model includes a breeding pond 1, a drain outlet 2 located at the bottom of the breeding pond 1, a water inlet pipe 3 for adding water to the breeding pond 1, and a drain pipe 4. The bottom end of the drain pipe 4 is connected to the drain outlet 2, and the drain pipe 4 and the breeding pond 1 form a communicating vessel structure. The drain pipe 4 is provided with an overflow outlet 5 and a forced discharge outlet 6. The height of the forced discharge outlet 6 is lower than that of the overflow outlet 5. An automatic valve device 7 is provided at the position of the forced discharge outlet 6 to control the connection or closure of the forced discharge outlet 6 with the outside. Compared with the existing traditional sewage discharge system that uses pure manual operation, when aquaculture is carried out using this utility model, water is continuously added to the breeding pond 1 through the water inlet pipe 3. Since the drain pipe 4 and the breeding pond 1 form a communicating vessel structure, when the forced discharge outlet 6 on the drain pipe 4 is in the closed state, the water in the breeding pond 1 will slowly flow out from the overflow outlet 5 of the drain pipe 4 under the action of pressure difference, which can keep the water in the breeding pond 1 clean. In a flowing state, it can play a certain role in sewage discharge in the aquaculture pond 1, better maintain the water quality in the aquaculture pond 1, and avoid the water quality in the aquaculture pond 1 deteriorating too quickly and requiring frequent strong sewage discharge. When the strong discharge port 6 on the drain pipe 4 is in a connected state, the water in the aquaculture pond 1 will be rapidly and in large quantities discharged from the strong discharge port 6 of the drain pipe 4 under the action of pressure difference. Since the liquid level difference between the strong discharge port 6 and the aquaculture pond 1 is large, when the strong discharge port 6 is connected, it can more fully discharge the aquatic excrement and uneaten feed deposited at the bottom of the aquaculture pond 1. After the strong sewage discharge is completed through the strong discharge port 6 for a certain period of time, the strong discharge port 6 is closed, thus repeating the automatic sewage discharge of the aquaculture pond 1. This utility model can replace the purely manual method to achieve automatic sewage discharge. The operation is very simple, time-saving and labor-saving, which can greatly reduce the labor intensity of aquaculture workers and can be better applied to the sewage discharge of aquaculture pond 1.
[0021] The automatic valve device 7 includes a control component 71, a sealing airbag 72 located at the forced discharge port 6, an inflation component 73 for inflating the sealing airbag 72, and a deflation component 74 for deflating the sealing airbag 72. This invention only requires controlling the opening or closing of the inflation component 73 and the deflation component 74 to control the expansion and contraction of the sealing airbag 72, thereby enabling the opening or closing of the forced discharge port 6. It can replace purely manual methods to achieve automatic sewage discharge, making operation very simple, time-saving, and labor-saving, greatly reducing the labor intensity of aquaculture workers, and is better suited for sewage discharge in aquaculture ponds 1. Furthermore, compared to simply controlling the opening or closing of the forced discharge port 6, by controlling the size of the sealing airbag 72, the drainage volume of the forced discharge port 6 can be controlled, making it more practical.
[0022] The inflation assembly 73 includes an inflation pump 731, an inflation pipe 732, and a one-way airflow valve 733 disposed on the inflation pipe 732. The output end of the inflation pump 731 is connected to the sealing airbag 72 through the inflation pipe 732. The control assembly 71 is electrically connected to the inflation pump 731. The one-way airflow valve 733 ensures that the sealing airbag 72 can only be inflated through the inflation pump 731, and there will be no backflow of gas, i.e., the gas of the sealing airbag 72 will leak out from the inflation pump 731, thereby ensuring a better inflation effect. The deflation assembly 74 includes a deflation port 741 connected to the inflation pipe 732 and a deflation valve 742 disposed at the position of the deflation port 741. When the deflation valve 742 is in the open state, the inflation pipe 732 is connected to the external atmospheric pressure through the deflation port 741.
[0023] The vent valve 742 can be a manual valve or a solenoid valve. Preferably, the vent valve 742 of this invention is a solenoid valve. The control component 71 is electrically connected to the solenoid valve, which automatically opens or closes the vent port 741. This eliminates the need for manual deflating of the sealing airbag 72, further reducing the workload of operators, improving automation, and enabling fully automatic sewage discharge, thus preventing situations such as forgetting to discharge or missing the optimal discharge time. Of course, in other embodiments, the vent valve 742 can also be a manual valve.
[0024] This utility model also includes a pressure gauge 75 for detecting the pressure inside the inflation pipe 732. The pressure gauge 75 allows for better observation of the pressure inside the inflation pipe 732, thereby enabling better adjustment of the size of the sealing airbag 72.
[0025] This utility model also includes an airbag mounting assembly 76 for fixing the sealing airbag 72. The airbag mounting assembly 76 can be a wire, a mounting bracket, etc. The airbag mounting assembly 76 can prevent the sealing airbag 72 from deviating, thereby ensuring that the sealing airbag 72 can effectively block the forced discharge port 6.
[0026] The sealing airbag 72 is made of rubber material, which can not only inflate and deflate well, but also has good wear resistance, making it suitable for sealing the forced discharge port 6.
[0027] This utility model also includes a display module 77. The control component 71 is electrically connected to the display module 77. The display module 77 can be used to observe the sewage discharge situation, and is especially suitable for multiple aquaculture ponds 1. It can intuitively observe the sewage discharge situation of each aquaculture pond 1, such as whether it is currently in a sewage discharge state, the number of sewage discharges, and the amount of sewage discharged.
[0028] This utility model also includes a communication module 78. The control component 71 is electrically connected to the communication module 78. The communication module 78 can be wired or wireless. The sewage discharge status of the aquaculture pond 1 can be sent to the monitoring backend, such as the display module 77, smartphone, control terminal, etc., through the communication module 78. The sewage discharge can also be remotely controlled through the communication module 78.
[0029] In this embodiment, the drainage pipe 4 is arranged vertically, and the drainage pipe 4 and the aquaculture pond 1 form a U-shaped communicating vessel structure; of course, in other embodiments, the drainage pipe 4 can also be set at an angle.
[0030] Working principle:
[0031] Water is continuously added to the aquaculture pond 1 through the water inlet pipe 3. The automatic valve device 7 controls the strong discharge port 6 on the drain pipe 4 to be closed, and the water in the aquaculture pond 1 slowly flows out from the overflow port 5 of the drain pipe 4. After a certain period of time, the automatic valve device 7 controls the strong discharge port 6 on the drain pipe 4 to be connected to the outside, and the water in the aquaculture pond 1 rapidly and in large quantities leaks out from the strong discharge port 6 of the drain pipe 4, completing the strong sewage discharge. After the strong sewage discharge is completed, the automatic valve device 7 controls the strong discharge port 6 on the drain pipe 4 to be closed, and water is continuously added to the aquaculture pond 1 through the water inlet pipe 3 until the liquid level in the aquaculture pond 1 is higher than the height of the overflow port 5 on the drain pipe 4, and the water in the aquaculture pond 1 slowly flows out from the overflow port 5 of the drain pipe 4. This utility model can replace the purely manual method to realize automatic sewage discharge. The operation is very simple, time-saving and labor-saving, which can greatly reduce the labor intensity of aquaculture workers and can be better applied to the sewage discharge of aquaculture pond 1.
[0032] Of course, the above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
