[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figures 1-4 An escape-proof leech farming cage includes a cubic cage body 100. The cubic design of the cage body 100 provides leeches with a regular activity space, facilitating centralized farming management. An opening 110 is located at the top of the cage body 100, serving as a channel for releasing leeches, feeding them, and observing their growth. An escape-proof door 120 is located at the top of the cage body 100, effectively preventing leeches from escaping through the opening 110. The cage body 100 is fitted and secured inside an external frame 200, which provides support to the cage body 100 and prevents it from collapsing due to [unspecified reasons]. Deformation occurs due to water flow impact or leech activity; the outer frame 200 includes multiple side rods 210 distributed on the outer periphery of the main body 100 of the net cage and several connectors 220 for connecting the ends of adjacent side rods 210. The side rods 210 form the skeleton of the outer frame 200, and the connectors 220 ensure the stability of the connection of the side rods 210, so that the outer frame 200 forms a stable overall structure; the top and bottom edges of the main body 100 of the net cage are respectively fixed to the side rods 210 at the corresponding positions. This fixing method can firmly install the main body 100 of the net cage on the outer frame 200 and prevent relative displacement between the main body 100 of the net cage and the outer frame 200 when the net cage moves in the water.

[0034] like Figure 1 and Figure 2 As shown, in this utility model, the escape-proof door 120 includes a metal frame 121 and a mesh 122 fastened to the metal frame 121. The metal frame 121 provides support for the escape-proof door 120, ensuring the stability of the shape of the escape-proof door 120. The mesh 122 can cover the opening 110 while ensuring gas exchange inside and outside the cage. One side of the metal frame 121 is fastened to the top surface of the cage body 100. This fastening method allows the escape-proof door 120 to be opened and closed flexibly, making it convenient to operate. The material of the mesh 122 is the same as that of the cage body 100, ensuring the consistency of the escape-proof performance and water resistance of the escape-proof door 120 and the cage body 100.

[0035] like Figure 1 and Figure 3 As shown, specifically, the bottom of the outer frame 200 is provided with several ground anchors 230. The ground anchors 230 can fix the entire net cage to the bottom of the aquaculture water area and prevent the net cage from moving due to water flow or wind waves. There are four ground anchors 230, which are fixed to the four side bars 210 at the bottom in an inclined manner. The four ground anchors 230 fix the outer frame 200 from different directions, and the inclined setting enhances the stability of the fixation. The bottom end of the ground anchor 230 is pointed, and the pointed design makes it easier for the ground anchor 230 to be inserted into the mud at the bottom of the water, which is convenient for installation and fixation.

[0036] It should be added that the main body of the net cage 100 is made of nylon mesh with a mesh count of 30-40. This mesh count of nylon mesh can prevent leeches from escaping and ensure that plankton and other organisms in the water can enter the net cage to provide food for the leeches. At the same time, nylon material has good water resistance and abrasion resistance, extending the service life of the main body of the net cage 100. The edges of the mesh are bound with thickened nylon strips and double-stitched with corrosion-resistant thread. The thickened nylon strips enhance the strength of the mesh edges, and the double-stitched corrosion-resistant thread further improves the sturdiness of the main body of the net cage 100 and prevents the edges of the mesh from being damaged during use. The connector 220 is a three-way engineering plastic part. The three-way structure can meet the connection requirements of the side rod 210. The engineering plastic material is lightweight and has good corrosion resistance, making it suitable for use in aquatic environments. The inner wall of the connector 220 is provided with anti-slip texture. The anti-slip texture increases the friction between the connector 220 and the side rod 210, making the connection between the side rod 210 and the connector 220 more stable and less prone to loosening.

[0037] like Figure 1 and Figure 4 As shown, further, the outer frame 200 is provided with a cleaning assembly 300. The cleaning assembly 300 is used to clean the suspended matter attached to the outer surface of the cage body 100 to prevent the mesh from being blocked. The cleaning assembly 300 includes four movable sleeves 310 respectively sleeved on the outside of four vertical side rods 210. The movable sleeves 310 are slidably connected to the side rods 210 and can slide up and down along the side rods 210 to provide guidance for the movement of the cleaning assembly 300. A protruding plate 311 is fixed to the outer end of the movable sleeve 310, and the protruding plate 311 provides a fixing point for the installation of the connecting rod 320. A connecting rod 320 is fixed between the two protruding plates 311 on two adjacent movable sleeves 310. The connecting rod 320 connects the adjacent movable sleeves 310 together so that the movable sleeves 310 can move synchronously and ensure the coordination of the overall movement of the cleaning assembly 300.

[0038] like Figure 4As shown, a brush plate 330 is provided between two adjacent side rods 210. The brush plate 330 is fixed to the inner side of the connecting rod 320, and the brush plate 330 provides an installation base for the bristles 331. Several bristles 331 are inserted into the inner surface of the brush plate 330. The ends of the bristles 331 are in contact with the outer surface of the net cage body 100. When the brush plate 330 moves, it can clean the surface of the net cage body 100 and remove suspended matter. When the movable sleeve 310 moves along the side rod 210, the movable sleeve 310 drives the connecting rod 320 and the brush plate 330 to move synchronously, realizing the comprehensive cleaning of the outer surface of the net cage body 100 by the bristles 331 and ensuring the cleaning effect.

[0039] like Figure 4 As shown, it is worth noting that the cleaning assembly 300 is provided with a pair of levers 340. The levers 340 are T-shaped and fixed to the top of the connecting rod 320. The T-shaped levers 340 are easy for the operator to hold. By moving the levers 340, the connecting rod 320 and the movable sleeve 310 can be moved, which facilitates the operation of the cleaning assembly 300.

[0040] In this embodiment of the escape-proof leech farming cage, the outer frame 200 is first fixed to the bottom of the farming area using the ground anchor 230, so that the cage body 100 is stably submerged in the water. Then, the escape-proof door 120 is opened, and leeches and feed are put into the cage body 100 through the opening 110. After that, the escape-proof door 120 is closed to prevent the leeches from escaping. Next, when it is necessary to clean the suspended matter on the outer surface of the cage body 100, the operator holds the lever 340 and drives the movable sleeve 310 to slide up and down along the side rod 210. The movable sleeve 310 drives the brush plate 330 and brush bristles 331 to move synchronously through the connecting rod 320 to clean the outer surface of the cage body 100. Finally, during the farming process, the growth of the leeches can be observed through the opening 110, and the escape-proof door 120 can be opened for relevant operations when necessary.
