Description

Technical Field

[0001] This utility model relates to the technical field of sewage treatment equipment, specifically a floating submersible pump mounting bracket for sewage tank drainage. Background Technology

[0002] In modern wastewater treatment systems, effective drainage of wastewater tanks is a key factor in ensuring the stable operation of the entire system. As a core piece of equipment commonly used in wastewater tank drainage operations, the rationality of the installation method of submersible pumps directly affects drainage efficiency and equipment lifespan.

[0003] Currently, when installing submersible pumps in sewage tanks, they are usually placed directly at the bottom of the tank or simply fixed to the tank wall. This installation method has many problems. On the one hand, because the water level in the sewage tank changes constantly with drainage, the fixed mounting bracket cannot automatically adjust the position of the submersible pump according to the water level changes. As a result, when the water level drops to a certain extent, the pump body will be exposed above the water surface, making it impossible to pump water normally, thus affecting the drainage efficiency. On the other hand, sewage often contains a large number of impurities, such as silt and floating matter. When the submersible pump is operating, these impurities can easily clog the pump's inlet, affecting the normal operation of the submersible pump and causing it to be easily damaged.

[0004] Therefore, this utility model provides a floating submersible pump mounting bracket for sewage tank drainage to solve the above problems. Utility Model Content

[0006] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a floating submersible pump mounting bracket for sewage tank drainage, comprising a base and a bracket fixedly connected to the upper surface of the base. Two limiting rods are symmetrically slidably connected to the inner side of the bracket. A connecting plate is fixedly connected between the top ends of the two limiting rods. A lead screw is rotatably connected to the lower surface of the connecting plate. A driven gear is fixedly connected to the bottom end of the lead screw, and the bottom end of the driven gear is rotatably connected to the upper surface of the bracket. A connecting frame is slidably connected between the outer sides of the two limiting rods. A mounting frame is fixedly connected between the inner sides of the connecting frame. An annular float is fixedly connected to the outer side of the mounting frame. A filter bucket is fixedly connected to the inner side of the top end of the mounting frame. A cleaning component is provided inside the mounting frame.

[0007] As a preferred technical solution of this application, a mounting base is fixedly connected to the upper surface of the bracket, a drive motor is fixedly connected to the inner side of the mounting base, a transmission gear is fixedly connected to the end of the output shaft of the drive motor, and the teeth of the transmission gear mesh with the teeth of the driven gear.

[0008] As a preferred technical solution of this application, an annular connecting seat is fixedly connected to the upper surface inside the mounting frame, and an internal toothed ring and a support frame are fixedly connected in sequence below the annular connecting seat on the inner side of the mounting frame.

[0009] As a preferred technical solution of this application, the cleaning component includes a fixed frame fixedly connected to the upper surface of the support frame, a submersible motor fixedly connected to the inner side of the fixed frame, a rotating plate fixedly connected to the end of the output shaft of the submersible motor, cleaning brushes rotatably connected to the inner walls of both ends of the rotating plate, a gear A fixedly connected to the bottom end of each cleaning brush, and the teeth of the gear A meshing with the teeth of the internal gear ring, and a limiting block fixedly connected to the top end of each cleaning brush, and the outer side of the limiting block slidingly adapting to the inner side of the annular connecting seat.

[0010] As a preferred technical solution of this application, an internally threaded connecting sleeve is fixedly connected to the inner side of the top of the filter bucket, and a bucket cover is threadedly connected to the inner edge of the internally threaded connecting sleeve. Two handles are symmetrically fixedly connected to the upper surface of the bucket cover.

[0011] As a preferred technical solution of this application, a submersible pump body is provided inside the filter barrel below the barrel cover, and multiple bolts are threadedly connected between the submersible pump body and the inner wall of the barrel cover.

[0012] (III) Beneficial Effects 1. The filter canister intercepts impurities such as silt and floating matter carried in the sewage, preventing blockage of the submersible pump's inlet port during pumping and thus extending its service life. The annular float, buoyed by the sewage tank's water level, causes the mounting frame and filter canister to slide vertically along the limiting rod via a connecting bracket. This allows the submersible pump's position to automatically adjust with water level changes, preventing it from being exposed above the water surface and thus ensuring proper pumping.

[0013] 2. By starting the submersible motor, the rotating plate is driven to rotate. During the rotation of the rotating plate, the two cleaning brushes and two gears A will revolve around the axis of the filter barrel. At the same time, the two gears A revolve around the axis of the filter barrel, and through the meshing with the internal gear ring, the two gears A can drive the two cleaning brushes to rotate synchronously. This achieves all-round brushing of the outer wall of the filter barrel, preventing the filter pores from becoming clogged. This ensures that the filter barrel can filter impurities in the sewage without affecting the working efficiency of the submersible pump due to the clogging of its own filter pores.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0017] Please see Figures 1-6As shown, the purpose of this embodiment is to provide a floating submersible pump mounting bracket for sewage tank drainage, including a base 1 and a bracket 2 fixedly connected to the upper surface of the base 1. Two limiting rods 301 are symmetrically slidably connected to the inner side of the bracket 2. A connecting plate 302 is fixedly connected between the top ends of the two limiting rods 301. A lead screw 303 is rotatably connected to the lower surface of the connecting plate 302. A driven gear 304 is fixedly connected to the bottom end of the lead screw 303, and the bottom end of the driven gear 304 is rotatably connected to the upper surface of the bracket 2. A connecting frame 305 is slidably connected between the outer sides of the two limiting rods 301. A mounting frame 306 is fixedly connected between the inner sides of the connecting frame 305. An annular float 307 is fixedly connected to the outer side of the mounting frame 306. A filter bucket 308 is fixedly connected to the inner side of the top end of the mounting frame 306. A cleaning component is provided inside the mounting frame 306.

[0018] A mounting base 201 is fixedly connected to the upper surface of the bracket 2. A drive motor 202 is fixedly connected to the inner side of the mounting base 201. A transmission gear 203 is fixedly connected to the end of the output shaft of the drive motor 202, and the teeth of the transmission gear 203 mesh with the teeth of the driven gear 304.

[0019] In this embodiment, the limiting rod 301 is used to guide and limit the connecting frame 305 so that the annular float 307 can only float along the vertical direction of the guide rod, and to limit the floating range of the annular float 307. By starting the drive motor 202, the drive motor 202 will drive the transmission gear 203 to rotate. When the transmission gear 203 rotates, it meshes with the driven gear 304, which in turn drives the lead screw 303 to rotate synchronously. Then, during the rotation of the lead screw 303, it engages with the connecting plate 302 through the threaded engagement, which drives the connecting plate 302 to drive the two limiting rods 301 to move up and down. In this way, by changing the height position of the bottom end of the limiting rod 301, the floating range of the annular float 307 can be limited, thus adapting to sewage tanks of different depths. When the submersible pump body 6 is pumping water inside the sewage tank, the filter barrel 308 ensures that the sewage in the sewage tank comes into contact with the filter barrel 308 before entering the inlet port of the submersible pump body 6. The filter holes of the filter barrel 308 then intercept large particles such as mud and floating objects carried in the sewage, thus preventing impurities in the sewage from clogging the inlet port of the submersible pump body 6 during pumping and affecting the service life of the submersible pump body 6. When the water level inside the sewage tank changes, the annular float 307 is buoyed by the water level in the sewage tank, which causes the mounting frame 306 and the filter barrel 308 to slide vertically along the outside of the limiting rod 301 via the connecting bracket 305. This allows the position of the submersible pump body 6 to automatically adjust with the water level change, ensuring that the submersible pump body 6 always maintains a suitable drainage position and preventing the submersible pump body 6 from being exposed above the water surface due to water level changes, which would prevent the submersible pump body 6 from being unable to pump water normally.

[0020] In this embodiment, as Figure 3 and Figure 4 As shown, an annular connecting seat 3061 is fixedly connected to the upper surface inside the mounting frame 306, and an internal toothed ring 3062 and a support frame 3063 are fixedly connected in sequence below the annular connecting seat 3061 on the inner side of the mounting frame 306.

[0021] The cleaning assembly includes a fixed frame 401 fixedly connected to the upper surface of the support frame 3063. A submersible motor 402 is fixedly connected to the inner side of the fixed frame 401. A rotating plate 403 is fixedly connected to the end of the output shaft of the submersible motor 402. Cleaning brushes 404 are rotatably connected to the inner walls of both ends of the rotating plate 403. Gears A405 are fixedly connected to the bottom end of each cleaning brush 404, and the teeth of gears A405 mesh with the teeth of the internal gear ring 3062. Limiting blocks 406 are fixedly connected to the top of each cleaning brush 404, and the outer side of the limiting blocks 406 is slidably adapted to the inner side of the annular connecting seat 3061.

[0022] In this embodiment, by starting the submersible motor 402, the submersible motor 402 will drive the rotating plate 403, which is fixedly connected, to rotate via the output shaft. During the rotation of the rotating plate 403, the two cleaning brushes 404 and the two gears A405 will revolve around the axis of the filter barrel 308. While the two gears A405 revolve around the axis of the filter barrel 308, through meshing with the internal gear ring 3062, the two gears A405 can drive the two cleaning brushes 404 to rotate synchronously. This achieves all-round brushing of the outer wall of the filter barrel 308, preventing the filter holes of the filter barrel 308 from becoming clogged. This ensures that the filter barrel 308 can filter impurities in sewage without affecting the working efficiency of the submersible pump body 6 due to the clogging of its own filter holes.

[0023] In this embodiment, as Figure 5 and Figure 6 As shown, an internally threaded connecting sleeve 501 is fixedly connected to the inner side of the top of the filter bucket 308, and a bucket cover 502 is threadedly connected to the inner edge of the internally threaded connecting sleeve 501. Two handles 503 are symmetrically fixedly connected to the upper surface of the bucket cover 502.

[0024] Below the cover 502, inside the filter barrel 308, there is a submersible pump body 6, and multiple bolts 7 are threadedly connected between the submersible pump body 6 and the inner wall of the cover 502.

[0025] In this embodiment, the threaded connection between the cover 502 and the internal threaded connecting sleeve 501, along with the handle 503, allows the operator to disassemble and assemble the cover 502 and the filter cartridge 308 without touching any tools. When the cover 502 and the filter cartridge 308 are separated, maintenance can be performed on the submersible pump body 6. When the cover 502 and the filter cartridge 308 are joined together, it ensures that when the submersible pump is pumping water, the sewage in the sewage tank can only enter the inlet of the submersible pump body 6 through the filter holes of the filter cartridge 308, thereby ensuring the filtration effect of the filter cartridge 308.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
