Description

Technical Field

[0001] This utility model relates to the field of submersible pump repair technology, specifically a submersible pump repair end cap removal device. Background Technology

[0002] A submersible pump is a type of pump that integrates the motor and pump body into one unit, allowing it to operate submerged in water. Submersible pumps typically resemble a cylinder in shape. Internally, they rely on a motor to drive an impeller, generating centrifugal force to extract and transport liquids. They are characterized by their overall sealing, compact design, and lightweight nature, and are commonly used in agricultural irrigation, urban drainage, and industrial water supply and drainage. The end caps in submersible pumps serve three main functions: mechanical support and fixation; sealing and protection; and guiding water flow.

[0003] When repairing a submersible pump, the end cover needs to be removed to inspect the impeller, shaft, seals, and clean foreign objects from the pump chamber. Due to prolonged contact with water, rust usually forms at the connection between the end cover and the pump body, making it difficult to remove the end cover. The common method used by repair personnel is to insert the blade of a flathead screwdriver into the gap and gently tap the handle of the screwdriver with a hammer or other tools to gradually wedge the screwdriver into the gap, thus opening a small gap between the end cover and the pump body. Then, a pry bar is used to pry the end cover by rotating it in a circular motion along the gap. This method is very time-consuming and physically demanding. Moreover, if the pry bar slips or excessive force is applied during prying, it may cause injury to the repair personnel, posing a certain safety hazard. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example: Figures 1-5 As shown, this utility model provides a technical solution for a submersible pump maintenance end cap disassembly device, including a hollow disassembly platform 100 and a movable plate 200;

[0031] Please refer to this carefully. Figures 1-4The movable plate 200 is slidably connected to the bottom of the inner cavity wall of the hollow disassembly table 100. A traction plate 210 is provided on the left side inside the movable plate 200, and a disassembly plate 211 is fixedly connected to the top of the traction plate 210. A movable plate 212 is provided on the right side inside the movable plate 200, and a connecting groove plate 213 is fixedly connected to the top of the movable plate 212. A first slot 220 is opened on the top left side of the movable plate 200, and the traction plate 210 is slidably connected to the inner cavity wall of the first slot 220. A rod 221 is slidably connected inside the traction plate 210, and the left and right ends of the rod 221 are connected to… The inner wall of the first slot 220 is fixedly connected. A spring 222 is sleeved on the outer wall of the rod 221. The spring 222 is located on the left side of the traction plate 210. A servo motor 223 is fixedly connected to the top of the movable plate 200 by bolts. The servo motor 223 is located on the right side of the first slot 220. The output shaft of the servo motor 223 is fixedly connected to a rotating block 224. The right side wall of the disassembly plate 211 contacts the left side wall of the movable plate 212. A second slot 230 is opened on the top right side of the movable plate 200. The bottom of the movable plate 212 is connected to the inner wall of the second slot 230. The bottom of the cavity wall is slidably connected. A screw-driven electric telescopic rod 240 is fixedly connected to the right side of the inner cavity wall of the hollow disassembly platform 100. The output end of the screw-driven electric telescopic rod 240 is fixedly connected to the right side wall of the movable plate 200. A movable opening 150 is opened on the top right side of the hollow disassembly platform 100. The top of the movable plate 212 extends to the outside of the movable opening 150, and the movable plate 212 is slidably connected to the movable opening 150. The right end of the tension plate 111 extends to the inner cavity of the connecting groove plate 213 and is slidably connected to the inner cavity wall of the connecting groove plate 213. This submersible pump maintenance The end cap removal device drives the rotating block 224 to rotate via the servo motor 223. The rotating block 224, in conjunction with the traction plate 210, the rod 221, and the spring 222, causes the removal plate 211 to move back and forth, striking the moving plate 212 and causing it to shift. The movement of the moving plate 212 drives the wedge-shaped inserts 113 on both sides to move simultaneously, thus removing the end cap. This allows the force to be applied evenly to the end cap during removal, making it easier to remove and ensuring safer operation.

[0032] Please refer to this carefully. Figure 1 , Figure 2 , Figure 3 and Figure 5Hollow clamping blocks 110 are provided on the top left side and front and rear sides of the hollow disassembly table 100. A tension plate 111 is slidably connected to the inner wall of the hollow clamping block 110. An installation screw 112 is slidably connected inside the tension plate 111. A wedge-shaped insert 113 is fixedly connected to one end of the installation screw 112. The wedge-shaped insert 113 is located inside the front and rear tension plates 111 and on the right side of the hollow clamping block 110. A fixing frame 120 is fixedly connected to the outer wall of the front and rear tension plates 111. The installation screw 112 is slidably connected to the inside of the fixing frame 120. A limit block 121 is screwed to the outer wall of the installation screw 112. The limit block 121 is located inside the fixing frame 120. A third slot 130 is opened on the top left side of the hollow disassembly table 100. The hollow clamping block 110 is slidably connected to the inner wall of the third slot 130. A double-direction fixing screw 131 is screwed into the interior of each hollow clamping block 110. The rear end of the double-direction fixing screw 131 is rotatably connected to the rear side of the inner cavity wall of the third slot 130 through a bearing. The front end of the double-direction fixing screw 131 extends to the outer side of the third slot 130. The inner side walls of the hollow clamping blocks 110 on both the front and rear sides are provided with nitrile rubber gaskets. The other end of the mounting screw 112 is fixedly connected to a circular block 140, which is located on the outer side of the fixing frame 120. This submersible pump maintenance end cover removal device fixes submersible pump bodies of different sizes through the hollow clamping blocks 110 on both sides, improving the overall applicability. At the same time, the wedge-shaped insert 113 cooperates with the mounting screw 112, the fixing frame 120 and the limiting block 121 to insert the wedge-shaped block into the connection between the end cover and the submersible pump body to create a gap, thereby facilitating subsequent disassembly.

[0033] In use, the submersible pump body is placed between the hollow clamping blocks 110 on both sides. Rotating the bidirectional fixing screw 131 simultaneously causes the hollow clamping blocks 110 on both sides to move in opposite directions, engaging with the third slot 130, thus fixing the submersible pump body. This positions the connection between the end cap and the submersible pump body at the wedge-shaped insert 113. Simultaneously, nitrile rubber gaskets provide friction to prevent relative movement during subsequent disassembly. The circular blocks 140 on both sides are then tapped with a tool, causing the circular blocks 140 to be installed... The lead screw 112 drives the wedge-shaped insert 113 to be inserted into the connection between the end cover and the submersible pump body, creating a gap. After completion, the limit blocks 121 on both sides are rotated to fix the wedge-shaped insert 113 in conjunction with the fixing bracket 120. After completion, the power supply of the servo motor 223 is turned on, and the output shaft of the servo motor 223 rotates, driving the rotating block 224 to rotate. When the longer end of the rotating block 224 contacts the traction plate 210, it pushes the traction plate 210 to the left to cooperate with the first slot 220 to slide on the rod 221. At the same time, the spring 222 is subjected to The compression causes contraction. When the longer end of the rotating block 224 moves away from the traction plate 210, the spring 222 rebounds, causing the traction plate 210 to return to its original position. The traction plate 210 then causes the disassembly plate 211 to strike the moving plate 212, generating a rightward force on the moving plate 212. The moving plate 212, through the connecting slot plate 213 and in conjunction with the tension plate 111, also applies the same force to the wedge-shaped insert 113. The wedge-shaped insert 113 then applies force to the end cap. As the rotating block 224 rotates, the disassembly plate 211 reciprocates against the moving plate. 212 is struck, causing the wedge-shaped insert 113 to loosen the end cover and detach it from the submersible pump body a certain distance. When the moving plate 212 moves to the rightmost side of the second slot 230, the power to the screw-driven electric telescopic rod 240 is turned on. The screw-driven electric telescopic rod 240 drives the movable plate 200 to move to the right, so that the moving plate 212 moves to the leftmost side of the second slot 230. The above-mentioned knocking operation of the disassembly plate 211 is repeated until the end cover is completely detached from the submersible pump body, thus completing the disassembly of the end cover.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
