DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0021] See also Figure 1 to Figure 3 The utility model provides a submersible aeration mechanism, comprising:

[0022] A central axis 1 is arranged on the bottom surface of the aeration tank, and the central axis 1 is fixedly connected to the bottom surface of the aeration tank;

[0023] The base 2 is fixedly connected to the bottom of the central axis 1. A top seat 22 is rotatably connected to the central axis 1 above the base 2. A top groove is provided on the top surface of the base 2. A bottom groove is provided on the top surface of the top seat 22. The base 2 and the top seat 22 are rotatably sealed. The top groove and the bottom groove cooperate to form a closed space. An air intake pipe 21 is provided on the base 2. The other end of the air intake pipe 21 is connected to a ventilation mechanism or a pipeline system. The air intake pipe 21 can introduce gas into the above-mentioned closed space. A plurality of extension plates 23 are evenly arranged on the top of the side wall of the top seat 22;

[0024] The movable seat 3 is slidably arranged above the extension plate 23, and the movable seat 3 corresponds to the extension plate 23 one by one. The top surface of the extension plate 23 is provided with a slide groove 24, and the bottom surface of the movable seat 3 is provided with a convex seat 33 slidably connected to the slide groove 24. The top surface of the movable seat 3 is provided with an aeration head 31, and the movable seat 3 is provided with a connecting pipe 32, one end of the connecting pipe 32 is connected to the aeration head 31, and the other end of the connecting pipe 32 is connected to the above-mentioned enclosed space.

[0025] The lifting seat 4 is arranged on the central axis 1, and a circulation groove is arranged on the surface of the central axis 1. The lifting seat 4 is provided with a guide column that cooperates with the circulation groove. A first connecting rod 41 is rotatably arranged between the lifting seat 4 and the moving seat 3 (that is, one end of the first connecting rod 41 is rotatably connected to the lifting seat 4, and the other end of the first connecting rod 41 is rotatably connected to the moving seat 3). When the top seat 22 drives the plurality of extension plates 23 and the moving seat 3 to rotate, under the action of the first connecting rod 41, the lifting seat 4 rotates synchronously with the top seat 22. Under the cooperation of the circulation groove and the guide column, the lifting seat 4 rotates and performs reciprocating lifting and lowering motion, thereby driving the moving seat 3 to rotate around the axis of the central axis 1 and reciprocate along the slide groove 24, thereby expanding the range of action of the aeration head 31 and improving the aeration effect.

[0026] The mating seat 5 is penetrated on the connecting tube 32, and is provided with a through hole mating with the connecting tube 32. The bottom surface of the mating seat 5 is rotatably connected to two second connecting rods 51, one end of the second connecting rod 51 away from the mating seat 5 is rotatably connected to the movable seat 3, and the other end of the second connecting rod 51 away from the mating seat 5 is rotatably connected to the side wall of the slide groove 24 close to the central axis 1.

[0027] See also Figure 1 to Figure 3 Preferably, an elastic member 34 is provided between the protrusion 33 and the side wall of the slide groove 24 away from the central column 1. When the elastic member 34 is in a natural state, the movable seat 3 is located at one end of the slide groove 24 close to the central axis 1, which can assist the movable seat 3 to reciprocate along the slide groove 24. The elastic member 34 is a spring.

[0028] See also Figure 1 to Figure 3 Preferably, the sides of the through hole on the matching seat 5 are provided with rounded corners to avoid scratching the connecting pipe 32.

[0029] See also Figure 1 to Figure 3 Preferably, the user can select the appropriate number of the devices according to actual conditions (generally, the aeration tank area is large, so multiple devices need to be installed on the bottom of the aeration tank). A plurality of gears 25 are provided on the top seat 22, and the gears 25 are used to cooperate with the chain, so that one power source can drive multiple top seats 22 to rotate, reducing the number of power sources used and reducing production and use costs.

[0030] During the implementation of the utility model, the user connects a plurality of gears 25 through a chain so that a power source can drive a plurality of top seats 22 to rotate. When aeration is required, the user starts the power source and the ventilation mechanism so that the top seat 22 drives the extension plate 23 to rotate, and the extension plate 23 drives the movable seat 3 and the aeration head 31 to rotate synchronously. Under the action of the first connecting rod 41, the lifting seat 4 rotates synchronously with the top seat 22. Since the central axis 1 is fixedly connected to the bottom surface of the aeration tank, the central axis 1 does not rotate. Therefore, under the cooperation of the circulation groove and the guide column, the lifting seat 4 rotates while reciprocating along the circulation groove. At the first connecting rod 41, the lifting seat 4 rotates. Under the action, when the lifting seat 4 rises, the moving seat 3 drives the aeration head 31 to move towards the direction close to the central axis 1. During this process, under the action of the second connecting rod 51, the matching seat 5 rises, thereby ensuring that the connecting pipe 32 is always in a tensioned state to avoid the connecting pipe 32 from being entangled and knotted; when the lifting seat 4 descends, the moving seat 3 drives the aeration head 31 to move away from the central axis 1, and the matching seat 5 descends. During the above process, the ventilation mechanism passes the gas along the air inlet pipe 21 into the enclosed space between the base 2 and the top seat 22, and passes it into the aeration head 31 through the connecting pipe 32. The gas enters the aeration tank from the aeration head 31 to complete the aeration.

[0031] The utility model provides a submersible aeration mechanism, which has the following beneficial effects:

[0032] 3. By setting up the central axis, lifting seat, first connecting rod and moving seat and other structures, the aeration head can rotate around the central axis while reciprocating along the slide, which expands the action range of the aeration head and improves the aeration effect;

[0033] 4. By setting up the matching seat and the second connecting rod and other structures, the connecting pipe can be automatically retracted and extended during the movement of the aeration head, ensuring that the connecting pipe is always in a tensioned state, avoiding the entanglement of the connecting pipe and ensuring good ventilation efficiency.

[0034] In summary, the beneficial effects of the utility model are: it can not only expand the action range of the aeration head and improve the aeration efficiency, but also automatically complete the retraction and extension of the connecting pipe to avoid its entanglement and knotting, thereby ensuring a good aeration effect.
