Abstract
Description
Technical Field
[0001] This utility model relates to the field of sewage lifting, and specifically provides a sewage lifting device. Background Technology
[0002] Wastewater lifting equipment is divided into built-in and external types. Built-in wastewater lifting equipment is especially suitable for low-frequency, long-term drainage scenarios, specifically for lifting clean water wastewater from household kitchens, washing machines, etc. If there is a lot of solid dirt in the water during drainage, it can easily cause blockage of the internal water pump, requiring timely cleaning.
[0003] However, the water pumps in existing sewage lifting equipment are generally fixed at the bottom. When cleaning the pumps is required, they need to be removed from the equipment's housing. When removing the pumps, they must be taken out along the opening of the housing. If the pumps tip over inside the housing, they may be removed from the opening or become stuck inside, making separation of the pumps from the housing complicated.
[0004] Accordingly, a new technical solution is needed in this field to solve the above problems. Utility Model Content
[0005] The present invention aims to solve the above-mentioned technical problems and address the difficulty in removing existing water pumps from their housings.
[0006] This utility model provides a sewage lifting device, comprising:
[0007] The box has an opening at its upper end, which forms an internal cavity.
[0008] The pump body is disposed within the receiving cavity, and its lower end is connected to the housing.
[0009] A pump body connector is connected to the pump body. The upper end of the pump body connector is provided with a first notch, and the lower end of the pump body connector is provided with a second notch. The extension line of the connection line between the first notch and the second notch is arranged to intersect the length direction of the housing.
[0010] A sliding assembly includes a fixed head and a sliding rod. The fixed head is connected to the inside of the opening position. The fixed head is provided with a sliding rod arranged along the length direction of the housing. The sliding rod passes through the first notch. The lower end of the sliding rod abuts against the lower end of the pump body connector. The sliding rod is configured such that when the pump body connector is removed from the housing, the sliding rod passes through the first notch and the second notch.
[0011] By employing the above technical solution, the cooperative design of the first and second notches of the sliding component and the pump body connector allows the pump body to slide directionally along an angle with the length of the housing during removal, avoiding the jamming problem caused by flipping during traditional vertical removal. The cross-shaped notch guide structure allows the pump body to pass through the opening during removal, avoiding difficulties in removing the pump body from the housing due to an insufficiently small opening, making it particularly suitable for maintenance scenarios in confined spaces.
[0012] In the specific embodiment of the above-mentioned sewage lifting equipment, the sliding assembly includes two sliding rods, which are located on both sides of a pump body connector.
[0013] When the above technical solution is adopted, the double-sided slide bar layout forms a symmetrical support structure, which enhances the stability of the pump body movement, prevents skew caused by unilateral force, and reduces mechanical wear.
[0014] In the specific implementation of the above-mentioned sewage lifting equipment, the number of the pump body, the pump body connector and the sliding assembly are all two.
[0015] In the specific embodiment of the above-mentioned sewage lifting equipment, a connecting block is provided on the inner side of the opening of the box, and the fixing head is connected to the connecting block.
[0016] In the specific embodiment of the above-mentioned sewage lifting equipment, an outer cover extension is provided on the upper side of the opening of the box body, and a cover body is connected to the outer cover extension by a hinge. The cover body is configured to cover the opening.
[0017] With the above technical solution adopted, the hinged cover design enables quick opening and closing of the opening, and combined with the sealing structure extending from the cover body, it effectively prevents sewage from splashing out.
[0018] In the specific embodiment of the above-mentioned sewage lifting equipment, the sewage lifting equipment further includes a base, which is disposed at the bottom of the inner side of the tank, and the pump body connector is connected to the base.
[0019] In the specific embodiment of the above-mentioned sewage lifting equipment, the sewage lifting equipment further includes a float fixing frame and floats. The upper end of the float fixing frame is fixedly connected to the outer extension of the cover body, and the lower end of the float fixing frame is fixedly connected to the base. There are multiple floats, and the multiple floats are arranged along the length direction of the float fixing frame.
[0020] With the above technical solution, the multi-point distribution structure of the float holder achieves both liquid level monitoring and mechanical support functions. This design ensures float sensitivity while improving the connection rigidity between the pump body and the tank.
[0021] In the specific embodiment of the above-mentioned sewage lifting equipment, the bottom of the tank is provided with a fixing recess facing the inside of the tank, and the base is connected to the fixing recess.
[0022] When the above technical solution is adopted, a fixing recess is provided to accommodate the screws of the fixing base, which facilitates the fixing of the base.
[0023] In the specific embodiment of the above-mentioned sewage lifting equipment, the bottom of the tank is provided with a drainage recess facing the inside of the tank and communicating with the fixing recess and the side of the tank.
[0024] When the above technical solution is adopted, the drainage recess design can guide the discharge of residual sewage and avoid water accumulation and corrosion of components.
[0025] In the specific implementation of the above-mentioned sewage lifting equipment, the number of drainage depressions is two.
[0026] When the above technical solution is adopted, the double drainage depression forms a two-way flow channel, which accelerates the drainage efficiency of water accumulated at the bottom of the box. Attached Figure Description

[0037] like Figures 1 to 6As shown, to solve the problem of difficulty in removing existing water pumps from the housing 1, this utility model provides a sewage lifting device, including: a housing 1 with an opening at its upper end forming a cavity; a pump body 5 disposed within the cavity and connected to the housing 1 at its lower end; a pump body connector 3 connected to the pump body 5; a first notch 32 at the upper end of the pump body connector 3 and a second notch 33 at the lower end of the pump body connector 3; the extension line of the connecting line between the first notch 32 and the second notch 33 intersects the length direction of the housing 1; and a sliding assembly including a fixed head 41 and a sliding rod 42. The fixed head 41 is connected to the inner side of the opening, and the sliding rod 42 is disposed on the fixed head 41 along the length direction of the housing 1. The sliding rod 42 passes through the first notch 32, and the lower end of the sliding rod 42 abuts against the lower end of the pump body connector 3. The sliding rod 42 is configured such that when the pump body connector 3 is removed from the housing 1, the sliding rod 42 passes through the first notch 32 and the second notch 33. Thus, through the cooperative design of the sliding component and the first notch 32 and the second notch 33 of the pump body connector 3, the pump body 5 can slide directionally in a direction that forms an angle with the length direction of the housing 1 when it is taken out, avoiding the jamming problem caused by flipping when taking it out vertically in the traditional way. The cross-set notch guide structure allows the pump body 5 to pass through the opening when it is taken out, avoiding the difficulty of taking the pump body 5 out of the housing 1 due to the opening being too small, which is especially suitable for maintenance scenarios in narrow spaces.
[0038] like Figures 1 to 6 As shown, in one or more embodiments, the sewage lifting equipment includes: a housing 1, a pump body 5, a pump body connector 3, and a sliding assembly.
