Description

Technical Field

[0001] The utility model relates to the field of deep well pumps, and specifically relates to a deep well pump with a buffer protection structure. Background Art

[0002] A deep well pump is a mechanical device used to extract water from deep wells. The deep well pump drives the impeller to rotate through an electric motor. Under the action of centrifugal force, water is sucked into the pump body from the bottom of the well, and then the water is lifted to the ground through pressure. It usually consists of an electric motor, a pump body, an impeller, a transmission shaft, etc., and is mainly applied in fields such as agricultural irrigation, drinking water supply, industrial water use, and geothermal utilization. Currently, the deep well pump needs to send the pump body into the groundwater well, and it is easy to collide during the transportation process. On the one hand, the damage rate of the pump body is relatively high. Therefore, a deep well pump with a buffer protection structure is needed.

[0003] For the existing deep well pumps, when in use, it is inconvenient to buffer and protect the pump body, so that the pump body directly bears the acting forces in all directions, which easily causes the parts of the pump body to become loose and damaged, shortening the service life of the pump body, and it is also inconvenient to disassemble and clean the filter screen of the pump body, resulting in the blockage of the filter screen. Content of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide a deep well pump with a buffer protection structure to solve the problems that the existing deep well pumps are inconvenient to buffer and protect the pump body and inconvenient to disassemble and clean the filter screen of the pump body.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A deep well pump with a buffer protection structure, including a pump body, a housing is fixedly connected to the outer wall of the pump body, a damping spring is installed inside the housing, a movable rod is movably connected inside the housing, a guiding block is fixedly connected to the outer wall of the movable rod, a frame plate is fixedly connected to one end of the movable rod, a rotating shaft is installed inside the frame plate, and a roller is fixedly connected to the outer wall of the rotating shaft.

[0006] A first filter screen is installed on the outer wall of the pump body, a clamping block is fixedly connected to the bottom of the first filter screen, a bolt is installed inside the first filter screen, a second filter screen is installed on the outer wall of the pump body, and a nut is installed on the outer wall of the bolt.

[0007] Preferably, the housing is of a slotted design, and the housing and the movable rod form a sliding structure through the guiding block.

[0008] Preferably, the guiding blocks are symmetrically arranged with respect to the central axis of the movable rod, and the frame plate is of a U-shaped design.

[0009] Preferably, the frame plate and the roller form a rotating structure through the rotating shaft, and the housings are arranged in a circular array centered on the central axis of the pump body.

[0010] Preferably, the pump body is of a slotted design, and the pump body forms a sliding structure with the first filter screen through a clamping block.

[0011] Preferably, the bolt is threadedly connected to the nut, and both the first filter screen and the second filter screen are of slotted designs.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. By providing the pump body, the housing, the damping spring, the movable rod, the support plate and the roller, when the pump body is placed in the well, when the pump body shakes in the well or collides with the well wall due to water flow impact, the roller can contact the well wall, and the roller can rotate along the support plate, so that the pump body can be lifted and lowered stably. When the roller is impacted by the well wall, the movable rod can slide along the housing and squeeze the damping spring, which has the effect of facilitating the buffer protection of the pump body, preventing the pump body from being damaged due to collision with the well wall, and improving the service life of the deep well pump;

[0014] 2. By providing the pump body, the first filter screen, the clamping block, the bolt and the second filter screen, by rotating the bolt, the limit on the first filter screen and the second filter screen can be released, and the first filter screen and the second filter screen can be pulled outwards, so that the clamping block can be moved out along the chute provided in the pump body, which has the effect of facilitating the disassembly and cleaning of the first filter screen and the second filter screen, and preventing impurities in the water from clogging the filter screen.

[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. The embodiments described below with reference to the accompanying drawings are exemplary only for explaining the present utility model and should not be construed as limiting the present utility model.

[0021] The embodiments of the present utility model will be described below according to its overall structure.

[0022] As Figures 1 to 4 shown, the deep well pump with a buffer protection structure includes a pump body 1. A sleeve 2 is fixedly connected to the outer wall of the pump body 1. A damping spring 3 is installed inside the sleeve 2. A movable rod 4 is movably connected inside the sleeve 2. A guide block 5 is fixedly connected to the outer wall of the movable rod 4. One end of the movable rod 4 is fixedly connected to a frame plate 6. A rotating shaft 7 is installed inside the frame plate 6. A roller 8 is fixedly connected to the outer wall of the rotating shaft 7. The sleeve 2 is designed with slots, and the sleeve 2 and the movable rod 4 form a sliding structure through the guide block 5. The guide block 5 is symmetrically arranged with respect to the central axis of the movable rod 4, and the frame plate 6 is U-shaped. The frame plate 6 and the roller 8 form a rotating structure through the rotating shaft 7, and the sleeve 2 is arranged in a circular array centered on the central axis of the pump body 1, which can facilitate the buffer protection of the pump body 1.

[0023] Furthermore, a first filter screen 9 is installed on the outer wall of the pump body 1. A clamping block 10 is fixedly connected to the bottom of the first filter screen 9. A bolt 11 is installed inside the first filter screen 9. A second filter screen 12 is installed on the outer wall of the pump body 1. A nut 13 is installed on the outer wall of the bolt 11. The pump body 1 is designed with slots, and the pump body 1 and the first filter screen 9 form a sliding structure through the clamping block 10. The bolt 11 and the nut 13 are in threaded connection, and both the first filter screen 9 and the second filter screen 12 are designed with slots, which can facilitate the disassembly and cleaning of the first filter screen 9 and the second filter screen 12.

[0024] During use, by placing the pump body 1 into the well, when the pump body 1 shakes in the well or collides with the well wall due to water flow impact, the roller 8 can be in contact with the well wall. Under the action of the rotating shaft 7, the roller 8 can rotate along the frame plate 6, enabling the pump body 1 to rise and fall stably. When the roller 8 is impacted by the well wall, under the action of the guide block 5, the movable rod 4 can slide along the sleeve 2 and compress the damping spring 3, enabling the damping spring 3 to buffer the impact force. By rotating the bolt 11, since the bolt 11 and the nut 13 are in threaded connection, the limit on the first filter screen 9 and the second filter screen 12 can be released. Pull the first filter screen 9 and the second filter screen 12 outwards, so that the clamping block 10 moves out along the chute opened in the pump body 1, and the first filter screen 9 and the second filter screen 12 can be disassembled and cleaned to prevent the water inlet of the deep well pump from being blocked. In this way, the use process of the device is completed. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
