[0016] Example: Figure 1-3As shown, the utility model provides an automatic control fixing device for a pneumatic submersible pump, comprising a water tank 1, a pneumatic submersible pump 3 and a magnetic switch 4. The magnetic switch 4 is electrically connected to an external air supply device through a wire, and the air inlet end of the pneumatic submersible pump 3 is connected to the external air supply device through a connecting pipe. The pneumatic submersible pump 3 is fixedly installed in the water tank 1, and a fixing component 2 is provided on the water tank 1, and a control component 5 is provided on the fixing component 2; the control component 5 includes a guide rod 51, an outer sliding sleeve of the guide rod 51 is provided with a float 52, an outer sliding sleeve of the guide rod 51 is provided with a supporting plate 53, an upper surface of the supporting plate 53 is provided with a push rod 54, a top end of the push rod 54 is fixedly provided with a magnet 55, the magnet 55 is used in conjunction with the magnetic switch 4, and a symmetrically distributed pull rope 56 is fixed on the lower surface of the supporting plate 53. The end away from the support plate 53 is fixedly connected to the outer side of the float 52, and the float 52 is driven upward by the buoyancy of the water. The float 52 pushes the support plate 53 to move through the sleeve 57, and the support plate 53 drives the push rod 54 to move, and the push rod 54 drives the magnet 55 to engage with the magnetic switch 4. The water level in the water tank 1 drops, and the float 52 drops synchronously. The float 52 separates the magnet 55 and the magnetic switch 4 through the pull rope 56. In this way, the opening and closing of the pneumatic submersible pump 3 can be controlled by the water level to avoid the inconvenience of manual control. The outer sliding sleeve of the guide rod 51 is provided with a sleeve 57, and the bottom end of the sleeve 57 is fixedly connected to the outer side of the float 52. The sleeve 57 can facilitate the movement of the support plate 53, and the bottom end of the guide rod 51 is fixedly provided with an anti-slip plate 58. The anti-slip plate 58 can prevent the float 52 from detaching from the guide rod 51.

[0017] The fixing assembly 2 includes a connecting rod 21, both ends of the connecting rod 21 are movably inserted with a support rod 22, and the end of the support rod 22 away from the connecting rod 21 is fixed with a fixing plate 23, and the fixing plate 23 is clamped on the water tank 1. The outer side of the connecting rod 21 is movably penetrated by a symmetrically distributed insertion rod 24, and the outer side of the support rod 22 is provided with a side-by-side distributed slot 25. One end of the insertion rod 24 is movably inserted into one of the slots 25, and a pull plate 26 is fixed on the top of the insertion rod 24. The pull plate 26 drives the insertion rod 24 to move out and move the support rod 22. The support rod 22 drives the fixing plate 23 to align with the edge of the water tank 1, and the insertion rod 24 is reset and inserted into the slot 25 by the elastic force, so that the insertion rod 24 fixes the connecting rod 21 and the support rod 22. This makes it convenient to fix the control assembly 5 on the water tank 1, and the fixing plate 23 The inner sliding card is provided with a clamping plate 27, and the outer thread of the fixing plate 23 is penetrated by a threaded rod 28. One end of the threaded rod 28 is rotatably connected to one side of the clamping plate 27. The threaded rod 28 is rotated to make the threaded rod 28 move on the fixing plate 23, and the threaded rod 28 drives the clamping plate 27 to move, so that the clamping plate 27 can cooperate with the fixing plate 23 to clamp the water tank 1. The outer movable sleeve of the insertion rod 24 is provided with a return spring 29, and the two ends of the return spring 29 are respectively fixedly connected to one side of the pull plate 26 and the outer side of the connecting rod 21. The return spring 29 can drive the pull plate 26 to return to its original position through the elastic force. The end of the threaded rod 28 away from the clamping plate 27 is fixed with a turntable 210, which can be easily rotated by the turntable 210. The magnetic switch 4 is fixedly mounted on the bottom of the connecting rod 21, which can be conveniently used with the magnet 55.

[0018] Working principle: First, move the pull plate 26, which drives the insertion rod 24 out of the slot 25. At the same time, the pull plate 26 stretches the reset spring 29, so that the reset spring 29 generates elastic force, and then move the support rod 22. The support rod 22 drives the fixing plate 23 to align with the edge of the water tank 1. The reset spring 29 drives the insertion rod 24 to return to the slot 25 through the elastic force, so that the insertion rod 24 fixes the connecting rod 21 and the support rod 22. Then, the fixing plate 23 is clamped to the water tank 1, and the turntable 210 is rotated. The turntable 210 drives the threaded rod 28 to rotate, so that the threaded rod 28 moves on the fixing plate 23. The threaded rod 28 drives the clamping plate 27 to move, so that the clamping plate 27 cooperates with the fixing plate 23 to clamp the water tank 1. In this way, the control component 5 can be conveniently fixed on the water tank 1, thereby achieving the purpose of convenient fixing.

[0019] When the water level in the water tank 1 rises, the buoyancy of the water drives the float 52 to move upward on the guide rod 51. The float 52 pushes the support plate 53 to move through the sleeve 57. The support plate 53 drives the push rod 54 to move. The push rod 54 drives the magnet 55 to engage with the magnetic switch 4. The magnetic switch 4 opens, and the external air supply device starts. The external air supply device starts to work and sends air through the connecting pipe to the pneumatic submersible pump 3, so that the pneumatic submersible pump 3 works to discharge the water tank 1. At the same time, the water level in the water tank 1 drops, and the float 52 and the sleeve 57 are synchronized. When the water level is low, the water level at the bottom of the pump 3 is too low to move, and the water level at the bottom of the pump 3 is too low to move.

Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
