[0014] The present invention provides a water pump connected with a buffer device, which has the following beneficial effects: (1) The buffer device is connected to the water pump. The buffer rod moves away from the pump body, driving the round block to move. The round block slowly slides on the inner wall of the sealing tube, driving the buffer rod to move slowly. The bellows can only stretch slowly, which provides buffer protection for the bellows and the external pipe at the connection of the bellows to prevent sudden pulling by external forces. The buffer device can reduce the vibration between the water pump and the pipe, thereby reducing the wear on the equipment and the pipe system. The buffer device can reduce the external force impact caused by the sudden change of the liquid flow speed in the pipe during the start and stop of the water pump or the operation process, which helps to protect the pipe and connectors from damage and reduce the need for pipe system maintenance.

[0015] (2) The buffer device is connected to the water pump. When the rotating blade rotates, it drives the friction strip to rotate. The protrusion on the surface of the friction strip contacts the bottom of the rack A and collides to generate vibration. The vibration of the rack A drives the filter frame to vibrate. The vibration of the filter frame prevents the debris adhering to the surface of the filter frame from clogging the filter frame. The debris and particulate matter on the surface of the filter frame may accumulate after running for a period of time, resulting in a decrease in the filtration efficiency. By regularly vibrating the filter frame, these adhering debris can be loosened and removed from the filter medium, thereby restoring the filtration efficiency. Vibrating the filter frame can reduce the maintenance frequency of the filtration system. Because the filter frame is not easily blocked, it does not need to be frequently shut down for cleaning or replacement of the filter medium, reducing the need for maintenance work.

[0016] (3) The buffer device is connected to the water pump. Gear B moves upward and is squeezed by rack B and starts to rotate. The rotation of gear B drives the breaker rod to rotate. The rotation of the breaker rod drives the blade to rotate. The rotation of the blade breaks up larger debris close to the filter frame. Large debris, such as leaves, plastic bags or other large pieces of matter, may block the inlet of the filter frame, thereby reducing the filtration efficiency or even causing the system to stop working. By breaking up these large pieces of debris with the rotating blade, it is possible to prevent them from clogging the filter, ensuring the normal operation of the system and improving the filtration efficiency.

[0017] (4) The structure has a buffer device connected to a water pump. When the support legs sink into the mud, the detection plate will move upward due to the reaction force of the mud. The support plate moves downward quickly to contact the bottom plane, thereby increasing the contact area between the support legs and the bottom plane. Increasing the contact area between the support legs and the bottom plane can increase the stability of the structure at the bottom of the water and reduce the risk of sinking. On soft bottom sediments, increasing the contact area can reduce the risk of sinking of the support legs or the structure, thereby preventing the structure from sinking to the bottom of the water or requiring frequent adjustments and maintenance.

The round block 42 sliding inside the sealing tube 41 is subjected to the negative pressure flow of the gas so that the round block 42 can only slide slowly on the inner wall of the sealing tube 41. The slow sliding of the round block 42 on the inner wall of the sealing tube 41 drives the buffer rod 43 to move slowly. The slow movement of the buffer rod 43 drives the bellows 2 to stretch slowly.

The protrusion on the surface of the friction strip 55 contacts with the bottom of the rack A56 to collide and generate vibration. The vibration of the rack A56 drives the filter frame 51 to vibrate. The vibration of the filter frame 51 prevents the debris adhering to the surface of the filter frame 51 from clogging the filter frame 51. The rotation of the vibration plate 58 drives the vibration block on the surface of the vibration plate 58 to rotate. The rotation of the vibration block contacts and collides with the filter frame 51 to generate vibration, which further enhances the vibration effect of the filter frame 51 to prevent debris from clogging the filter frame 51.

By regularly vibrating the filter frame 51, these adhered debris can be loosened and removed from the filter medium, thereby restoring the filtration efficiency. Vibrating the filter frame 51 can reduce the maintenance frequency of the filtration system, because the filter frame 51 is not easily blocked, so there is no need to frequently shut down for cleaning or replacement of the filter medium, reducing the need for maintenance work.

[0025] When the present embodiment is working, the water pump is put into the water bottom for normal operation. When the bellows 2 is pulled quickly by an external force, the bellows 2 is deformed and stretched. The stretching of the bellows 2 drives the buffer rod 43 to move in the direction away from the pump body 1. The buffer rod 43 moves in the direction away from the pump body 1, driving the round block 42 to move. The round block 42 moves and squeezes the gas on the side of the sealing tube 41 away from the pump body 1. The gas on the side of the sealing tube 41 away from the pump body 1 is squeezed by the movement of the round block 42 and enters the other side of the sealing tube 41 through the buffer hole opened on the surface of the round block 42. The round block 42 sliding inside the sealing tube 41 is affected by the negative pressure flow of the gas, so that the round block 42 can only slide slowly on the inner wall of the sealing tube 41.

The bellows 2 can only It can slowly stretch to provide buffering protection for the bellows 2 and the external pipe at the connection between the bellows 2. At the same time, when the external force quickly pulls the bellows 2 to the elastic limit, the bellows 2 is stretched to drive the buffer rod 43 to move away from the pump body 1. The buffer rod 43 moves away from the pump body 1 and drives the round block 42 to move. The movement of the round block 42 drives the limit rod 45 to move. The limit rod 45 moves to the elastic limit of the bellows 2 so that the limit groove on the surface of the limit rod 45 contacts the free end of the telescopic block 47. The limit groove on the surface of the limit rod 45 contacts the free end of the telescopic block 47 to form a limit. The limit groove and the free end of the telescopic block 47 form a limit so that the buffer rod 43 cannot move away from the pump body 1. The buffer rod 43 cannot move away from the pump body 1, so that the bellows 2 body cannot be pulled further, thereby achieving the effect of protecting the bellows 2 body structure.

At the same time, the rotation of the crushing rod 63 drives the toggle plate 67 to toggle back and forth, and the debris crushed by the blade 64 is thrown away from the vicinity of the filter frame 51.

[0032] When the water pump is put into the water bottom, the supporting legs 3 come into contact with the water bottom plane. If the water bottom plane is relatively soft, the supporting legs 3 may sink into the mud under the action of the gravity of the pump body 1 itself. When the supporting legs 3 sink into the mud, the detection plate 71 moves upward due to the reaction force of the mud. The detection plate 71 moves upward due to the reaction force of the mud, driving the protection block 76 to move upward. The protection block 76 moves upward and contacts the protection rod 75 to squeeze the bottom of the protection rod 75. The bottom of the protection rod 75 is squeezed by the protection block 76 and moves in a direction away from the pump body 1. The protection rod 75 moves in a direction away from the pump body 1 to release the limit between the protection rod 75 and the free end of the telescopic column 73. After the limit between the free end of the telescopic column 73 and the protection rod 75 is released, the free end of the telescopic column 73 moves downward rapidly. The free end of the telescopic column 73 moves downward rapidly, driving the supporting plate 74 to move downward rapidly. The supporting plate 74 moves downward rapidly and contacts the water bottom plane, thereby increasing the contact area between the supporting leg 3 and the water bottom plane and reducing the possibility of the water pump sinking into the mud.
