Description

Technical Field

[0001] This utility model belongs to the field of sewage discharge equipment technology, and in particular relates to a suspended submersible sewage pump. Background Technology

[0002] A suspended submersible sewage pump is a device used in the sewage treatment process to discharge sewage. It can draw sewage from a low place to a place where it can be discharged. It is widely used in the field of sewage discharge equipment. Existing suspended submersible sewage pumps include a float and a pump body. The buoyancy generated by the air inside the float makes the pump body float on the water surface to carry out sewage discharge work.

[0003] Existing suspended sewage pumps still have some problems in use. First, after prolonged use, the water in the pool flows around the pump body when the pump body draws water in, causing floating weeds or other floating debris to accumulate near the pump body. As the pump continues to work, the accumulated weeds will cover the pump inlet. Even though the current sewage pumps have a structure to clean the inlet, the weeds do not disappear after cleaning. They will come closer again as the pump continues to work, resulting in poor cleaning effect. Utility Model Content

[0004] This invention provides a suspended submersible sewage pump, which aims to solve the problem that current sewage pumps are easily covered and blocked by floating objects after long-term use, and the cleaning effect is not good.

[0005] This utility model is implemented as follows: a suspended submersible sewage pump includes a fixed frame; a float is installed on the outer wall of the fixed frame, the float is annular, an isolation cover is installed on the outer wall of the float, the isolation cover is annular, the float is located at the inner center of the isolation cover, a pump body is installed at the inner center of the fixed frame, a water supply pipe is installed on the top of the pump body, a water inlet is opened on the side wall of the fixed frame, a cover plate is installed on the top of the fixed frame, a connecting sleeve is installed at the center of the cover plate, a barrier ring is installed on the surface of the water supply pipe, the connecting sleeve is pressed onto the upper end of the barrier ring, a bracket is installed on the upper end of the float, a limit ring is installed on the top of the bracket, and the water supply pipe passes through the lower side of the limit ring upwards.

[0006] Preferably, the isolation cover is configured as a frustum shape, with both the upper and lower ends of the isolation cover being open.

[0007] Preferably, the water inlet is opened at an upward angle from the inside out.

[0008] Preferably, the cover plate is installed on the upper end of the fixed frame by two sets of screws, the inner wall of the connecting sleeve is seamlessly fitted with the surface of the water pipe, and the inner side of the connecting sleeve corresponding to the water pipe is made of hard plastic material.

[0009] Preferably, a support frame is installed at the bottom of the fixed frame, a support plate is installed at the bottom of the support frame, and a pulley is installed at the bottom of the support plate.

[0010] Preferably, the top of the support frame has a sliding groove and a sliding plate is slidably inserted therein. A fixing pin is installed on the upper side wall of the support frame. The surface of the fixing pin is threaded. The side wall of the sliding plate is equally spaced and has threads that are compatible with the threads on the surface of the fixing pin.

[0011] Compared with the prior art, the embodiments of this application have the following main advantages:

[0012] After prolonged use, the tiny impurities in the water are adsorbed onto the outside of the inlet of this sewage pump. By stopping the pump, the water is allowed to flow back, and the backflowing water backwashes the inlet quickly and effectively. The isolation cover is half underwater and half above water, allowing floating debris to accumulate upwards instead of spreading downwards, preventing aquatic plants and debris from being sucked to the outside of the fixed frame. The support frame and support plate work together to support the entire sewage pump, preventing the bottom of the device from sinking into the silt due to the water level dropping. The installation of pulleys facilitates the movement of the entire device. Attached Figure Description

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0019] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0020] This utility model embodiment provides a suspended submersible sewage pump, such as Figure 1-4 As shown, the device includes a fixed frame 1, a float 2 mounted on the outer wall of the fixed frame 1 (the float 2 is annular), an isolation cover 3 mounted on the outer wall of the float 2 (the isolation cover 3 is annular), the float 2 located at the inner center of the isolation cover 3, a pump body 4 mounted at the inner center of the fixed frame 1, a water supply pipe 5 mounted on the top of the pump body 4, a water inlet 6 opened on the side wall of the fixed frame 1, a cover plate 7 mounted on the top of the fixed frame 1, a connecting sleeve 8 mounted at the center of the cover plate 7, a barrier ring 9 mounted on the surface of the water supply pipe 5, the connecting sleeve 8 pressed onto the upper end of the barrier ring 9, a bracket 10 mounted on the upper end of the float 2, a limit ring 11 mounted on the top of the bracket 10, and the water supply pipe 5 passing through the lower side of the limit ring 11 upwards. When in use, the entire device can be placed in water. The float 2 suspends the entire device under the buoyancy of the water surface. At this time, the fixed frame 1 is located below the water surface. The sewage in the pool flows into the fixed frame 1 through the water inlet 6 on the side wall of the fixed frame 1 and is discharged from the water pipe 5 by the pump body 4. When the device is draining, half of the isolation cover 3 is underwater and half is above the water, which can prevent floating objects on the water surface from accumulating on the edge of the device and causing blockage. After the sewage pump has been used for a long time, the tiny dirt in the water is adsorbed on the outside of the water inlet 6. At this time, the pump body 4 can be stopped. Since the water pipe 5 is raised by the bracket 10, the water inside the pipe will flow back, and the backflowing water will flow out from the water inlet 6 of the fixed frame 1 to achieve backwashing. The flushing process is fast and effective.

[0021] The isolation cover 3 is set in a frustum shape, with both the upper and lower ends of the isolation cover 3 being open. By setting the isolation cover 3 in a frustum shape, floating objects on the water surface can accumulate upwards instead of spreading downwards, thus preventing aquatic plants and debris from being sucked to the outside of the fixed frame 1.

[0022] The water inlet 6 is opened at an upward angle from the inside out. This design ensures that the water enters from the water surface rather than the bottom, preventing underwater silt and other substances from being sucked in.

[0023] The cover plate 7 is installed on the upper end of the fixed frame 1 by two sets of screws. The inner wall of the connecting sleeve 8 fits seamlessly with the surface of the water pipe 5. The inner side of the connecting sleeve 8 corresponding to the water pipe 5 is made of hard plastic. The cover plate 7 and the fixed frame 1 are detachably connected, which facilitates the subsequent maintenance of the pump body 4. The connecting sleeve 8 and the water pipe 5 are sealed to prevent water in the water pipe 5 from leaking out from the gap between the connecting sleeve 8 and the water pipe 5 when it flows back.

[0024] A support frame 12 is installed at the bottom of the fixed frame 1, a support plate 13 is installed at the bottom of the support frame 12, and a pulley 16 is installed at the bottom of the support plate 13. By setting up the support frame 12 and the support plate 13, the support frame 12 and the support plate 13 can cooperate to support the entire sewage pump, preventing the bottom of the device from sinking into the silt due to the water level dropping. The installation of the pulley 16 can facilitate the movement of the entire device.

[0025] The top of the support frame 12 has a sliding groove and a sliding plate 14 is slidably inserted therein. A fixing pin 15 is installed on the upper side wall of the support frame 12. The surface of the fixing pin 15 is threaded. The side wall of the sliding plate 14 is equally spaced with threads that match the threads 15 on the surface of the fixing pin. By providing the sliding plate 14, the sliding installation of the sliding plate 14 allows the distance between the support plate 13 and the fixing frame 1 to be adjusted, thus facilitating its use in pools with different silt thicknesses.
