Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection technology, in particular to a device for collecting and processing fish excrement in aquaculture cages. Background Art

[0002] Cage aquaculture is a type of aquaculture method. Due to its low investment, high yield, mobility and quick results, it has flourished in lakes and reservoirs across the country in just a few decades. Aquatic products usually produce a large amount of feces during cage aquaculture. The large accumulation of fish feces will seriously affect the water quality and cause eutrophication of the water body, which will lead to the disease or death of aquatic products and further cause cost losses. In order to avoid the above phenomenon, farmers generally use fish feces treatment equipment to treat the fish feces.

[0003] Most existing treatment devices only consider the treatment of fish feces without considering its recycling and reuse, resulting in serious waste of resources. In addition, the fish feces treated by most treatment devices are wet, which is not only difficult to transport and increases the labor burden of farmers, but also not conducive to long-term storage, resulting in poor practicality.

[0004] The existing patent (publication number: CN209185398U) discloses an environmentally friendly aquatic product breeding cage fish feces collection and treatment device.

The treatment box, the collection box and the drying trough of the utility model are used in combination. The collection box can extract fish feces from the bottom end of the breeding cage and play a certain buffering role, thereby reducing the direct impact of feces on the treatment box and extending its service life. The treatment box can intercept fish feces and filter and disinfect the separated sewage. The drying trough can dry and recycle the intercepted fish feces. The three work together to solve the problem of fish feces accumulation while also collecting it, saving energy and protecting the environment, and improving resource utilization.

[0005] In view of the above problems, the existing patent provides a solution, but it lacks a structure for collecting fish feces in multiple containers, resulting in the user frequently needing to take out the collection device before cleaning the fish feces, thereby reducing the efficiency of fish feces collection and increasing the user's workload.

[0006] Therefore, a device for collecting and processing fish excrement in aquaculture cages is proposed. Utility Model Content

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. The aquaculture cage body of the present application provides a suitable growth environment for fish. Its connection with the collection mechanism and the filtering mechanism enables fish feces to be collected and processed in time, keeping the aquaculture water clean, which is beneficial to the healthy growth of fish. The float plate ensures that the collection mechanism floats stably on the water surface, making it easy to connect and operate with the aquaculture cage body. When the servo motor receives the signal from the microcontroller, it can accurately drive the turntable to rotate, realize automatic switching of the filter tank, improve the efficiency of fish feces collection and processing, and reduce manual intervention. The turntable provides an installation position for the filter tank. By rotating, different filter tanks can be quickly switched to ensure the continuity of fish feces collection.

[0034] In this embodiment, by setting the filter tank 31 to store fish feces and perform preliminary filtration, when one filter tank 31 is full, it can be switched to another filter tank 31 to continue collecting by rotating the turntable 23, thereby improving the collection efficiency and reducing the frequency of replacing the collection device. The filter screen 32 effectively separates fish feces and water, preventing fish feces from entering subsequent pipes and equipment, and ensuring the normal operation of the system. At the same time, filter screens 32 of different pore sizes can be selected as needed to improve the filtration effect. The fixing hole 33 provides an installation position for the pressure rod 34. When the filter tank 31 is full, the fish feces will press the pressure rod 34 to apply pressure to the pressure plate 29, triggering the automatic switching operation of the entire collection device. Its operation is simple and convenient, and the working efficiency is improved. The torsion spring 35 is the pressure rod 34. It provides elastic restoring force. After the fish feces in the filter tank 31 are collected by the user, the torsion spring 35 will drive the pressure plate 29 to reset, which is convenient for the user to use next time. The water inlet pipe 36 transports the water and fish feces mixture pumped out by the water pump 37 to the filter tank 31. Its position is close to the top left side of the filter tank 31 to ensure that the mixture can enter the filter tank 31 evenly, thereby improving the filtering effect. The water pump 37 provides power to pump the fish feces and water mixture in the aquaculture cage body 1 into the filter mechanism 3 for processing.

[0041] Working principle: First, the user places the aquaculture cage body 1 in a suitable aquaculture water area. During the aquaculture process, when it is necessary to collect and process fish feces, the user energizes and starts the water pump 37. Then, the water pump 37 extracts the mixture of fish feces and water in the aquaculture cage body 1 through the water pumping pipe 38 and the connecting pipe 39. The extracted mixture is then transported to the filter tank 31 through the water inlet pipe 36. A filter screen 32 is provided at the bottom inner side of the filter tank 31, which can effectively separate fish feces and water. Afterwards, when the fish feces in the filter tank 31 gradually accumulates to full, the fish feces will exert a pressure on the pressure rod 34. After being subjected to the pressure of the fish feces, the pressure rod 34 will apply pressure to the pressure plate 29, and the pressure plate 29 will then transmit the pressure to the pressure sensor 27. The pressure sensor The sensor 27 monitors the pressure changes on the pressure plate 29 in real time. Once it detects that the filter tank 31 is full of fish feces, it will send a signal to the microcontroller 25. After receiving the signal from the pressure sensor 27, the microcontroller 25 quickly issues an instruction to start the servo motor 22. After receiving the signal from the microcontroller 25, the servo motor 22 can accurately drive the turntable 23 to rotate. When the turntable 23 rotates, the full filter tank 31 will be rotated to another position, and the empty filter tank 31 will be rotated to the bottom of the output end of the water inlet pipe 36 to continue collecting fish feces. Finally, when the collection and processing device needs to be maintained, the user can remove the filter tank 31 that has collected fish feces and clean and collect the fish feces inside the filter tank 31.
