[0025] The purpose, advantages, and features of this utility model will be illustrated and explained through the following non-limiting description of preferred embodiments. These embodiments are merely typical examples of applying the technical solutions of this utility model, and all technical solutions formed by equivalent substitutions or equivalent transformations fall within the scope of protection claimed by this utility model.

They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] The submersible pump lifting mechanism disclosed in this utility model is described below with reference to the accompanying drawings. Figure 1 As shown, it includes a submersible pump 200 disposed in a water tank 100. A cover plate 300 is provided at the opening of the water tank 100. The cover plate 300 is provided with an inlet and outlet 310 corresponding to the position of the submersible pump 200. The submersible pump 200 is movably connected to a vertical guide rail 400 in the water tank 100. The submersible pump 200 is connected to a lifting device 500 that drives its lifting and lowering. The lifting device 500 is disposed on a bracket 600. The bracket 600 is fixed to the ground around the water tank 100.

[0028] The water tank 100 can be a sewage collection tank, and its size and shape can be designed as needed, which is not limited here. The cover plate 300 is located on the stepped surface at the opening of the water tank 100 and the top of the cover plate 300 does not protrude above the ground surface. The cover plate 300 can be a known metal cover plate, a high-strength fiber cement concrete cover plate, a resin cover plate, etc., which is not limited here.

[0029] The submersible pump 200 includes a base and a pump body disposed on the base. The base is movably disposed on the vertical guide rail 400. For example, the base can be slidably disposed on the vertical guide rail 400 by a slider.

[0030] As attachedFigure 1 Appendix Figure 2 As shown, the base is movably mounted on the vertical guide rail 400 via rollers 210, and the upper end of the vertical guide rail 400 extends close to the cover plate 300.

[0031] To facilitate actual maintenance operations, the submersible pump 200 needs to be raised above the cover plate 300. At this time, the submersible pump 200 will be separated from the vertical guide rail 400. Therefore, in order to facilitate the restoration of the connection between the roller 210 and the vertical guide rail 400 after maintenance, the roller 210 is a V-shaped wheel and is distributed on opposite sides of the vertical guide rail 400. The vertical guide rail 400 has a limiting protrusion 410 corresponding to the wheel groove of the V-shaped wheel. At the same time, the vertical guide rail 400 is fixed on the mounting bracket 800 in the water tank.

[0032] As attached Figure 1 As shown, to improve safety, an openable and closable door 700 is provided at the inlet / outlet 310, located on the side of the lifting chain 550 of the lifting equipment. One side of the door 700 is hinged to one side of the inlet / outlet 310, and the door 700 does not completely cover the inlet / outlet 310 so that pipes and lifting chains (not shown in the figure) can extend into the water tank 100 from the outside.

[0033] As attached Figure 1 As shown, in order to avoid the submersible pump 200 being damaged by the maintenance work performed by the staff on the cover plate 300, the bracket 600 includes a horizontal guide rail 610, at least one end of which extends to the outside of the cover plate 300, and the lifting equipment 500 is horizontally movable on the horizontal guide rail 610.

[0034] As attached Figure 3 As shown, the horizontal guide rail 610 is, for example, an I-beam. The lifting device 500 includes an electric hoist 510. The top of the electric hoist 510 is rotatably connected to the horizontal guide rail 610 via a roller assembly 520. The roller assembly 520 includes a movable seat 521 and traveling wheels 522 and limiting wheels 523 disposed on the movable seat 521. The traveling wheels 522 are rotatably disposed on the support plate 611 of the horizontal guide rail 610 and located on both sides of the vertical part 612 of the horizontal guide rail 610. The limiting wheels 523 are attached to both sides of the vertical part 612.

[0035] To facilitate the fixing of the I-beam, as shown in the attached document... Figure 1As shown, the bracket 600 includes a crossbeam 620 connecting the horizontal guide rail 610. The crossbeam 620 can be a known profile. The I-beam and the profile can be fixed by screwing or welding. At the same time, the two ends of the crossbeam 620 are respectively connected to connecting rods perpendicular to it. A support leg 630 is vertically arranged below the two ends of the two connecting rods.

[0036] To ensure the horizontal installation of the crossbeam 620 and prevent the electric hoist 510 from moving, as shown in the attached... Figure 4 As shown, each support leg 630 is connected to the ground via a leveling mechanism 640. The leveling mechanism 640 includes a base plate 641, on which at least one screw 642 is vertically mounted. The screw 642 is fixed to an adjusting plate 645 via an adjusting nut 643 and a fastening nut 644. The adjusting plate has a through hole for the screw to pass through. The adjusting plate 645 is fixed to the lower end of each support leg 630. During installation, the position of the adjusting nut 643 and the fastening nut 644 on the screw is adjusted to adjust the position of the adjusting plate 645, thereby adjusting all four adjusting plates 645 to the same height, ultimately achieving leveling of the horizontal guide rail 610.

[0037] The lower end of the lifting rope of the electric hoist 510 is connected to the submersible pump 200 via a hook. Meanwhile, as shown in the attached... Figure 1 As shown, the electric hoist 510 is provided with a downwardly extending operating rod 530, and the operating rod 530 is provided with a controller 540 for controlling the electric hoist 510.

[0038] When maintenance is required on the submersible pump 200, the electric hoist 510 is lifted from the water tank 100 to above the cover plate 300 by the controller 540 on the operating lever 530. Then, the electric hoist 510 is moved to the outside of the cover plate 300 by the operating lever 530, and the submersible pump 200 is maintained by the operator. After maintenance, the electric hoist 510 is moved by the operating lever 530 to align the submersible pump 200 with the inlet and outlet 310. Then, the electric hoist 510 is controlled to drive the submersible pump 200 to move down. During the downward movement, the rollers 210 of the submersible pump 200 are aligned with the vertical guide rail 400, so that the rollers 210 on the submersible pump 200 move down to both sides of the vertical guide rail 400.

[0039] This utility model has many other embodiments. All technical solutions formed by equivalent transformation or equivalent transformation fall within the protection scope of this utility model.
