[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figures 1 to 3 This utility model provides a technical solution: a fish sorting device for a fish lifter, including a sorting pool 1 and a screen assembly 2. A valve-controlled discharge pipe is installed at the bottom of one side of the sorting pool 1, and a fish passage is provided near the top on the other side. The screen assembly 2 separates fry and other fish of different sizes. The screen assembly 2 includes a support frame 21 and a screen 22 located on top of the support frame 21 and inclined. The inclination of the screen 22 and its cooperation with the fish passage adopt the structure mentioned in the background art. The support frame 21 is located in the sorting pool 1 and slides up and down. When the support frame 21 moves up and down, it can drive the screen 22 to move up and down, facilitating the discharge of other sorted fish through the fish passage.

[0023] In this technical solution, an opening and closing screen door 6 is provided on the screen 22. When the opening and closing screen door 6 is open, maintenance personnel can easily enter the area below the screen 22 to collect and clean the garbage at the bottom of the sorting pool 1.

[0024] Specifically, the screen 22 includes a rectangular outer frame 221, long round tubes 222 and short round tubes 223. The long round tubes 222 are arranged in a row inside the rectangular outer frame 221, and the short round tubes 223 are arranged in a row inside the rectangular outer frame 221 and are located on one side of the long round tubes 222. Thus, the gap between adjacent long round tubes 222 and adjacent short round tubes 223 is the screening gap. One end of the short round tube 223 is suspended. The gap between the suspended end and the rectangular outer frame 221 forms a manhole. The opening and closing screen door 6 includes a positioning plate 61 and a row of guide shafts 62 fixedly arranged on one side of the positioning plate 61. One end of the guide shaft 62 is sleeved on one end of the short round tube 223 and the two are slidably engaged. One guide shaft 62 corresponds to one short round tube 223. Pulling the positioning plate 61 back and forth can control the opening and closing of the manhole.

[0025] The long supporting tube 2211 and the short supporting tube 2212 fixedly connected with the bottom and the supporting frame 21 are welded at the position of the bottom of the rectangular outer frame 221 and close to the corner, so that the rectangular outer frame 221 can be in an inclined distribution state.

[0026] Further, the cleaning brush 7 is adhered to the outer periphery of the rectangular outer frame 221, and the cleaning brush 7 abuts against the inner wall of the sorting pool 1, so that the inner wall of the sorting pool 1 can be cleaned when the rectangular outer frame 221 moves up and down, the accumulation of adhering objects is avoided, and the maintenance period is greatly prolonged.

[0027] In the technical solution, the air floating force assembly 3 is arranged at the bottom of the supporting frame 21, the air supply part 4 for supplying air to the air floating force assembly 3 is arranged outside the sorting pool 1, after water is injected into the sorting pool 1, when the air floating force assembly 3 is inflated, the air floating force assembly 3 generates the floating force for pushing the supporting frame 21 to move upwards, and then the mesh screen assembly 2 is driven to move upwards, and after the air floating force assembly 3 is exhausted, the supporting frame 21 will descend by gravity.

[0028] Specifically, the supporting frame 21 is a rectangular frame, and the two sides of the supporting frame 21 are provided with the groove wheels 211, the two side walls in the sorting pool 1 are fixedly connected with the guide rails 11 which are in rolling cooperation with the groove wheels 211, the two sides of the bottom of the supporting frame 21 are provided with the air floating force assemblies 3, and the air floating force assemblies 3 are arranged close to the groove wheels 211, so that the movement of the supporting frame 21 to float upwards is more smooth.

[0029] The air floating force assembly 3 comprises the cage type cylinder 31 and the air bag 32 located in the cage type cylinder 31, the cage type cylinder 31 plays a role of protecting the air bag 32, one end of the air bag 32 is fixedly connected with the adapter pipe 321, the adapter pipe 321 is arranged through one end of the cage type cylinder 31, and the adapter pipe 321 is fixedly connected with the cage type cylinder 31.

[0030] In the embodiment, the air supply part 4 comprises the air pump 41 and the inflation and deflation control valve 42, the inflation and deflation control valve 42 is connected with the air pump 41 and the adapter pipe 321 through a pipeline, when the inflation and deflation control valve 42 is started to inflate the air bag 32 after the air pump 41 is started, the air bag 32 is inflated by the inflowing air and generates the floating force. Conversely, the inflation and deflation control valve 42 is operated to be in the exhaust position, the air bag 32 is exhausted, and the floating force generated by the air bag 32 is reduced.

[0031] Working principle: when it is necessary to clean the garbage below the mesh screen 22, the maintenance personnel descend to the upper side of the mesh screen 22 in the sorting pool 1 by using the ladder, then hold the positioning plate 61 and pull, at this time, the manhole is in an open state, the maintenance personnel descend to the lower side of the mesh screen 22 through the manhole, and then the garbage at the bottom of the sorting pool 1 can be cleaned.
