The limiting piece 202 further comprises limiting blocks 202d, limiting plates 202e and limiting rings 202f, the limiting blocks 202d are fixed at the top of the connecting plate 202a and located on two sides of the movable plate 202b, the limiting plates 202e are fixed between the two limiting blocks 202d, limiting grooves P are formed in the connecting plate 202a, the limiting plates 202e are located in the limiting grooves P, and the limiting rings 202f are located between the movable plate 202b and the triggering plate 202 c.
When the trigger plate 202c is pushed inward by the push plate 201c, the limiting 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 limit plate 202e and the limit groove P limit the submersible pump body, so that the submersible pump body is prevented from shifting in the left and right moving process.
The pushing member 203 includes 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 pulls up the immersible pump body 105, fixed plate 201a and link 201b lose the gravity that immersible pump body 105 gave it, through reset spring 203b pulling fly leaf 202b and trigger plate 202c outside removal this moment for spacing ring 202f breaks away from between fly leaf 202b and the trigger plate 202c, simultaneously through trigger plate 202c with push pedal 201c and link 201b jack-up, make it reset, can take out immersible pump body 105 this moment, very big improvement dismantlement efficiency.
When in use, the support box 101 is placed in a water pit needing pumping and draining, in an initial state, the movable pipe 102 is subject to the floating force of the floating block 104d and water to be in a floating trend, the slide bar 103b is positioned in the first sliding groove J, the connecting frame 201b is positioned in the fan-shaped groove on the support box 101, then the submersible pump body 105 is placed in the movable pipe 102, the fixed ring 201d is contacted with the fixed plate 201a, at this time, the fixed ring 201d and the connecting frame 201b are pressed downwards by the gravity of the submersible pump body 105, the push plate 201c is driven to move downwards by the connecting frame 201b, the trigger plate 202c and the movable plate 202b are pushed to move inwards by the push plate 201c until the limiting ring 202f is clamped between the movable plate 202b and the trigger plate 202c, so that the submersible pump body 105 is limited, meanwhile, the movable pipe 102 is subject to the pressure of the submersible pump body 105 to move downwards, so that the slide bar 103b slides in the first sliding groove J, because the first chute J is a fan-shaped downward slope, the movable pipe 102 rotates in the downward moving process until the sliding rod 103b slides into the second chute K, at this time, due to the rotation of the movable pipe 102, the connecting frame 201b is separated from the fan-shaped groove on the supporting box 101 and moves below the supporting box 101, then the supporting box 101 is filled with water due to the gravity of the submersible pump body 105, at this time, the submersible pump body 105 is subjected to a certain buoyancy force, and under the combined action of the buoyancy force block 104d, the movable pipe 102 has a upward moving trend, the sliding rod 103b slides upward in the second chute K, and meanwhile, the top of the connecting frame 201b contacts with the bottom of the supporting box 101, so that the movable pipe cannot move upward in use, namely, the installation of the submersible pump body 105 is more stable, the occurrence of unexpected falling is avoided, and then the pumping operation can be performed through the submersible pump body 105, at this time, sediment in water can be settled downwards, and water is filtered through the filter cartridge 301 in the pumping and draining process, so that excessive impurities, larger sand and stones and the like are prevented from entering the submersible pump body 105, and are blocked, meanwhile, when the submersible pump body 105 pumps water, the water flows upwards from the second water inlet G, the water on the other side flows sideways, a flow difference is formed, so that the impeller 303b can be driven to rotate slowly from one side, the impeller 303b and the fixed shaft 303a drive the mounting ring 304a and the scraping plate 304b to rotate through the fixed shaft 303a when rotating, the side surface of the filter cartridge 301 is prevented from being scraped through the scraping plate 304b, and the situation that the first water inlet H is blocked in the long-time use process is avoided, so that the water pumping port of the submersible pump body 105 is blocked in the pumping and draining process is avoided;
when the submersible pump body 105 needs to be taken out, a worker manually pulls the submersible pump body 105 and the movable pipe 102 upwards, and applies a rotating force to the movable pipe 102 in the process of pulling upwards, so that the sliding rod 103b can slide into the first sliding groove J, the connecting frame 201b is reset to the fan-shaped groove on the supporting box 101 in the process of moving upwards, the fixed plate 201a and the connecting frame 201b lose the gravity given to the submersible pump body 105, at the moment, the movable plate 202b and the trigger plate 202c are pulled to move outwards through the reset spring 203b, the limiting ring 202f is separated from the space between the movable plate 202b and the trigger plate 202c, and meanwhile, the push plate 201c and the connecting frame 201b are jacked upwards through the trigger plate 202c, so that the submersible pump body 105 can be reset, the whole installation and disassembly process does not need additional tools, and the stability is strong in use.
