The position-limiting member 202 includes a connecting plate 202a, a movable plate 202b and a trigger plate 202c, the connecting plate 202a is fixed in the second through hole L, the movable plate 202b slides on the top of the connecting plate 202a, and the trigger plate 202c is fixed on the top of the movable plate 202b and is matched with the push plate 201 c.
The connecting plate 202a is rectangular, a reinforcing rib is arranged between the movable plate 202b and the trigger plate 202c to improve the strength of the connecting plate, the trigger plate 202c is inclined, and the contact position of the push plate 201c is chamfered, so that when the push plate 201c moves downwards, the trigger plate 202c can be pushed to move inwards.
The limiting member 202 further includes limiting blocks 202d, limiting plates 202e and limiting rings 202f, the limiting blocks 202d are fixed on the top of the connecting plate 202a and located on two sides of the moving plate 202b, the limiting plates 202e are fixed between the two limiting blocks 202d, a limiting groove P is formed in the connecting plate 202a, the limiting plates 202e are located in the limiting groove P, and the limiting rings 202f are located between the moving plate 202b and the trigger plate 202 c.
When the trigger plate 202c is pushed inwards by the push plate 201c, the limit ring 202f is clamped between the movable plate 202b and the trigger plate 202c, so that the submersible pump body 105 is limited, and is prevented from shaking up and down in the use process, and when the movable plate 202b moves left and right, the submersible pump body is limited by the limit plate 202e and the limit groove P, and is prevented from shifting in the left and right movement process.
The pushing member 203 comprises a baffle 203a and a return spring 203b, the baffle 203a is fixed on the top of the connecting plate 202a, and two ends of the return spring 203b are respectively fixed with the baffle 203a and the movable plate 202 b.
When the staff upwards pulls immersible pump body 105, fixed plate 201a and link 201b lose the gravity that immersible pump body 105 gave it, move to the outside through reset spring 203b pulling movable plate 202b and trigger plate 202c this moment for spacing ring 202f breaks away from between movable plate 202b and the trigger plate 202c, jack-up push pedal 201c and link 201b upwards through trigger plate 202c simultaneously, make it reset, can take out immersible pump body 105 this moment, very big improvement dismantlement efficiency.
When the submersible pump is used, the supporting box 101 is placed in a pit to be pumped and drained, in an initial state, the movable pipe 102 is in a floating trend under the buoyancy of the buoyancy block 104d and water, at the moment, the sliding rod 103b is positioned in the first sliding groove J, the connecting frame 201b is positioned in the fan-shaped groove on the supporting box 101, then the submersible pump body 105 is placed in the movable pipe 102, so that the fixed ring 201d is in contact with the fixed plate 201a, at the moment, the fixed ring 201d and the connecting frame 201b are pressed downwards by the self gravity of the submersible pump body 105, the push plate 201c is driven by the connecting frame 201b to move downwards, the trigger plate 202c and the movable plate 202b are pushed to move inwards by the push plate 201c until the limit ring 202f is clamped between the movable plate 202b and the trigger plate 202c, so as to limit the submersible pump body 105, and at the same time, the movable pipe 102 moves downwards along with the pressure of the submersible pump body 105, so that the sliding rod 103b slides in the first sliding groove J, the first sliding groove J inclines downwards in a fan shape, so that the movable tube 102 also rotates in the process of moving downwards until the sliding rod 103b slides into the second sliding groove K, at the moment, the connecting frame 201b is separated from the fan-shaped groove on the supporting box 101 due to the rotation of the movable tube 102 and moves to the lower part of the supporting box 101, then the supporting box 101 is filled with water due to the gravity of the submersible pump body 105, at the moment, the submersible pump body 105 is subjected to certain buoyancy, the movable tube 102 has the trend of moving upwards under the combined action of the connecting frame and the buoyancy block 104d, the sliding rod 103b slides upwards in the second sliding groove K, and the top of the connecting frame 201b is contacted with the bottom of the supporting box 101, so that the submersible pump body cannot move upwards in use, even if the installation of the submersible pump body 105 is more stable, and the occurrence of an accident is avoided, then the pumping and discharging operation can be carried out through the submersible pump body 105, and the silt in the water can be settled downwards, and the water is filtered by the filter cartridge 301 in the pumping and draining process, so that excessive impurities and larger sand and stone and the like are prevented from entering the submersible pump body 105 to cause blockage, meanwhile, when the submersible pump body 105 pumps water, water flows upwards from the second water inlet hole G, and water on the other side flows to the side, so that a flow difference is formed, so that the impeller 303b can be driven to rotate slowly from one side, and when the impeller 303b and the fixed shaft 303a rotate, the mounting ring 304a and the scraping plate 304b are driven to rotate by the fixed shaft 303a, so that the side surface of the filter cylinder 301 is scratched by the scratching plate 304b, the first water inlet hole H is prevented from being blocked in the long-time use process, thereby avoiding the situation that silt blocks the water pumping port of the submersible pump body 105 in the pumping and discharging process;
when the submersible pump body 105 needs to be taken out, the worker manually pulls the submersible pump body 105 and the movable pipe 102 upwards, and applies a rotational force to the movable tube 102 during the upward pulling, so that the slide bar 103b can slide into the first sliding slot J, so that the coupling frame 201b is restored into the sector groove of the supporting box 101 during its upward movement, and the fixed plate 201a and the connection frame 201b lose the gravity given to them by the submersible pump body 105, at this time the movable plate 202b and the trigger plate 202c are pulled by the return spring 203b to move to the outside, so that the stop collar 202f is disengaged from between the movable plate 202b and the trigger plate 202c, simultaneously through trigger plate 202c with push pedal 201c and link 201b jack-up upwards, make it reset, can take out immersible pump body 105 this moment, whole installation and the process of dismantling need not with the help of extra instrument, and the steadiness is strong during the use.
