Abstract
Description
Technical Field
[0001] This utility model belongs to the field of submersible pump technology, and in particular relates to a stamping submersible pump. Background Technology
[0002] A stamped submersible pump is a commonly used type of submersible pump. Components such as the impeller, guide vane, and inlet section are formed using a stamping process. The impeller is typically made of stainless steel sheet through stamping and stretching processes to form a trumpet-shaped base and a butterfly-shaped top plate, which are then welded to the impeller blades. This process results in a precise impeller shape and a smoother flow channel compared to traditional cast impellers, effectively reducing liquid flow resistance and improving the pump's hydraulic efficiency.
[0003] Most existing submersible pump filters are fixed structures, which are inconvenient to install and disassemble. When a large amount of impurities in the liquid, such as fibers and particles, adhere to the filter surface, causing the filter holes to become clogged, cleaning and replacing the filter can be quite cumbersome. Usually, it is necessary to disassemble multiple parts with professional tools before the filter can be processed. This not only consumes a lot of manpower, resources and time, but also causes the submersible pump to be shut down for a long time. Utility Model Content
[0004] To address the problems existing in the prior art, this utility model provides a stamping submersible pump. When it is necessary to clean or replace the filter screen, pull the protruding part of the filter screen and lift it outwards to disengage the hook from the mesh of the filter screen surface. Then, pull the elastic stop to pull the slide bar out from the inside of the annular groove, thereby removing the filter screen for easy cleaning or replacement. At the same time, the annular groove and slide bar setting play a limiting role in the use of the filter screen, preventing the filter screen from shifting and loosening.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a stamping submersible pump, including a submersible pump body, an inlet section movably connected to one end of the submersible pump body, a guide block fixedly connected to the surface of the inlet section, an annular groove formed on the surface of both the guide block and the inlet section, a slide bar slidably connected inside the annular groove, an elastic stop block fixedly connected to one end of the slide bar, a filter screen fixedly connected to the opposite surfaces of the two slide bars, and multiple hooks fixedly connected to the surface of the filter screen.
[0006] Furthermore, the slide bar is made of corrosion-resistant rubber, and the submersible pump body is made of stainless steel.
[0007] Furthermore, the filter screen is convex in shape and is a flexible metal filter screen.
[0008] Compared with the prior art, the beneficial effects of this utility model are:
[0009] 1. When cleaning or replacing the filter screen, pull the protruding part of the filter screen and lift it outwards to disengage the hook from the mesh of the filter screen. Then, pull the elastic stop to pull the slide bar out of the annular groove. This allows you to remove the filter screen for easy cleaning or replacement. The annular groove and slide bar also limit the movement of the filter screen during use, preventing it from shifting or loosening.
[0010] 2. When installing the filter screen, insert the ends of the two slide bars away from the stop block into the annular grooves on the guide block. Then, pull the filter screen to rotate one full circle along the inlet section and tighten it. At this time, the elastic stop block is compressed. Through the setting of the elastic stop block, the elastic stop block contacts the guide block and plays a limiting role. Finally, insert the buckle on the filter screen into the mesh holes on its surface. After releasing the filter screen, the slide bar will be reset under the action of the elastic stop block, thereby resetting the filter screen. At this time, the hook is engaged and fixed with the mesh holes on the filter screen. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and 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. Therefore, they should not be construed as limitations on this utility model. Example
[0019] See appendix Figure 1-5 As shown, a submersible pump includes a pump body 1. One end of the pump body 1 is movably connected to an inlet section 2. A guide block 3 is fixedly connected to the surface of the inlet section 2. Both the guide block 3 and the surface of the inlet section 2 are provided with annular grooves 4. A slide bar 5 is slidably connected inside the annular groove 4. One end of the slide bar 5 is fixedly connected to an elastic stop block 6. Filter screens 7 are fixedly connected to the opposite surfaces of the two slide bars 5. Multiple hooks 8 are fixedly connected to the surface of the filter screen 7.
[0020] The slide bar 5 is made of corrosion-resistant rubber, and the submersible pump body 1 is made of stainless steel.
[0021] The filter screen 7 is shaped like a convex character and is a flexible metal filter screen 7.
[0022] Working principle: When the submersible pump body 1 is running, the liquid to be transported enters through the inlet section 2. The filter screen 7 covers the inlet area of the inlet section 2. The liquid is first filtered by the filter screen 7, and impurities are intercepted on the outside of the filter screen 7. When it is necessary to clean or replace the filter screen 7, pull the protruding part of the filter screen 7 and lift it outward to make the hook 8 disengage from the mesh of the filter screen 7. Then pull the position of the elastic stop 6 to pull the slide bar 5 out of the inside of the annular groove, so that the filter screen 7 can be removed for cleaning or replacement. When installing the filter screen 7, insert the ends of the two slide bars 5 away from the stop block into the guide block 3 respectively. Inside the groove, pull the filter screen 7 around the inlet section 2 and rotate it once, tightening it. At this time, the elastic stop 6 is squeezed. Through the setting of the elastic stop 6, the elastic stop 6 contacts the guide block 3 to play a limiting role. Finally, insert the buckle on the filter screen 7 into the mesh hole on its surface. After releasing the filter screen 7, the elastic stop 6 rebounds and drives the slide bar 5 to reset, thereby driving the filter screen 7 to reset. At this time, the hook 8 is locked and fixed to the mesh hole of the filter screen 7. At the same time, through the setting of the annular slide groove 4 and the slide bar 5, the filter screen 7 is limited during use to prevent the filter screen 7 from shifting and loosening.
[0023] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model 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 basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model, and no reference numerals in the claims should be construed as limiting the scope of the claims.
[0024] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
