Description

Technical Field

[0001] The utility model relates to the field of mechanized fishing of aquatic products, in particular to a fish-water separation device with good buffering function. Background Art

[0002] In the current mechanized fishing of aquatic products, the equipment used mainly includes vacuum fish suction pumps, centrifugal fish suction pumps, jet fish suction pumps and other types. When these equipment are used to carry out fishing operations, the situation presented is often that the fish will be discharged from the outlet of the fishing equipment along with a large amount of water. Generally speaking, the ratio of fish to water generally reaches 1:4 or even higher, and sometimes there will be more water mixed in. In many cases, it is necessary to properly separate the fish and water, and ensure that the fish will not be damaged in the process, and then weigh the fish and other subsequent treatments. However, the actual situation is that most of the fish obtained by existing mechanized fishing is directly discharged into the fish frame to complete the collection and drainage operations. In this process, the fish will impact the inside of the fish frame in a very direct and violent manner, which will cause a considerable impact on the fish, and some of the fish will accidentally fall to the ground due to this impact, which will undoubtedly cause a greater degree of damage to the fish. Especially for the situation that the fish may be damaged due to impact when the fish suction pump is discharging the fish. The existing designs, patent application numbers 202022056571.0 and 202320351282.4, designed the structure of the fish-water separation device, but there is no buffer device, and patent application number 201920976106.3, although a certain buffer device is designed, the fish and water still directly hit and fall on the filter, which will still cause damage to some fish. It is urgent to design a fish-water separation device with good buffering function, so as to achieve the goal of lossless separation of fish and water through such a design, so as to better ensure the quality of the catch and the effectiveness of the fishing operation.

[0003] Therefore, it is necessary to design a fish-water separation device with good buffering function. Utility Model Content

[0004] In view of the technical defects existing in the background technology, the utility model proposes a fish-water separation device with good buffering function, which solves the above technical problems and meets the actual needs. The specific technical solution is as follows:

[0005] A fish-water separation device with good buffering function comprises a fish suction pump and a fish-water separation device, wherein a universal slot is arranged on the left side of the fish-water separation device, the fish suction pump is connected to the fish-water separation device through the universal slot, the right side of the fish-water separation device is a fish-water separator outlet, a curved water retaining block is arranged inside the fish-water separation device, a stainless steel filter is arranged at the bottom of the curved water retaining block, the fish-water separation device is also provided with a driving device for driving the curved water retaining block, and a CCD camera cooperating with the driving device is arranged on the upper right side of the fish-water separation device.

[0006] Furthermore, the fish-suction pump includes a vacuum fish-suction pump, a centrifugal fish-suction pump and a jet fish-suction pump.

[0007] Furthermore, a water return port cooperating with a stainless steel filter is provided at the front end of the fish-water separation device.

[0008] Furthermore, the driving device includes a screw motor, and the screw motor drives the curved water retaining block to move left and right above the stainless steel filter.

[0009] Furthermore, the left side of the fish suction pump is a fish inlet bell mouth and is connected to the fish-water separation device through a fish outlet pipe.

[0010] Furthermore, a fish outlet valve is provided at the connection between the fish outlet pipe and the fish-water separation device.

[0011] Furthermore, a vacuum tank is provided in the fish suction pump.

[0012] Furthermore, a plurality of universal brake wheels are arranged at the bottom of the fish-water separation device.

[0013] Compared with the prior art, the fish-water separation device with good buffering function provided by the utility model has the following beneficial effects:

[0014] In the fish-water separation device of the utility model, fish and water accumulate to a certain height under the action of the curved water retaining block. The curved water retaining block with an arc-shaped design effectively simulates the natural swimming trajectory of fish, reducing fish injuries and stress reactions; then, the water flow carries the fish into the right area, where the spacing of the stainless steel filter screen is carefully designed to effectively intercept the fish and ensure that the water body is unobstructed, thereby achieving preliminary fish-water separation. A CCD camera is installed on the upper right end of the fish-water separator device. The camera has a real-time image capture function and can accurately determine the distribution ratio of fish and water at the outlet. The linkage design of this visual system and the curved water retaining block enables the water retaining block to move left and right according to the real-time image data provided by the CCD camera through the screw motor drive, and dynamically adjust its position. This intelligent adjustment mechanism allows the machine to accurately control the degree of shielding of the stainless steel filter screen according to the actual flow rate and fish size, and optimize the passage of water and fish. This design not only ensures that the fish are wrapped in lubricating water when discharged, reducing damage and stress response to the fish body, but also improves the efficiency and accuracy of the entire separation process. The filtered water returns to the pond through the drainage pipe, while the separated fish and a small amount of water flow to the outlet of the fish-water separator and are finally collected by the fish frame. The entire design fully considers the ease of operation and quality protection of the catch, thereby improving fishing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
