Abstract
Description
Technical Field
[0001] This utility model relates to the field of submersible sewage pumps, specifically a pipe connection device for submersible sewage pumps. Background Technology
[0002] Submersible sewage pumps are submersible sewage pumps that can tear and cut long fibers, bags, belts, grass, rags, and other materials in sewage and then discharge them smoothly. They are particularly suitable for conveying liquids containing hard solids, fibrous materials, and particularly dirty, sticky, or slippery liquids. They are widely used in sewage treatment, urban drainage, and industrial wastewater discharge. When connecting the water hose to the outlet pipe of a submersible sewage pump, pipe clamps or wire are mostly used to tie the hose. The sealing performance is poor. During the pump start-up and shutdown, if the pipe clamps or wire are not tied securely, or when the water flow fluctuates, the hose is very likely to fall off and needs to be re-secured. If the drainage well or drainage area is deep, or when pumping sewage, there are certain safety hazards or inconveniences in re-secured hoses. Therefore, a pipe connection device for submersible sewage pumps is needed.
[0003] An existing pipe connection device for submersible sewage pumps has several drawbacks. Firstly, it cannot prevent blockages when connecting the submersible sewage pump to the pipe. Secondly, it is inconvenient to clean the connection point between the pipe and the submersible sewage pump, and it is difficult to ensure the stability of the connection. Therefore, there is an urgent need for a pipe connection device for submersible sewage pumps. Utility Model Content
[0004] Based on this, the purpose of this utility model is to provide a pipe connection device for submersible sewage pumps, so as to solve the problems that existing pipe connection devices for submersible sewage pumps cannot prevent blockage when connecting the submersible sewage pump and the pipe, and are not convenient for cleaning the connection position between the pipe and the submersible sewage pump, and are not convenient for ensuring the stability of the connection position.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a pipe connection device for a submersible sewage pump, comprising a connecting frame, connectors installed at both ends of the connecting frame, limit holes formed on the surface of the connectors, threaded holes formed inside the connecting frame, a filter screen installed inside the connecting frame, threaded rods installed at both ends of the filter screen, a sliding groove formed on the inner wall of the connecting frame, a sealing cover installed at the upper end of the connecting frame, a fastening rod installed at the outer end of the sealing cover, and a partition plate installed at the lower end of the sealing cover.
[0006] Preferably, the limiting holes are arranged in a circular array with the connectors, and the connectors are symmetrically arranged with respect to the central axis of the connecting frame.
[0007] Preferably, the filter screen is connected by a connecting frame via a thread, and the filter screen is arranged symmetrically with respect to the central axis of the connecting frame.
[0008] Preferably, the sealing cap is threadedly connected to the connecting frame via a fastening rod, and the sealing cap fits tightly against the connecting frame.
[0009] Preferably, the partition plate forms a sliding structure with the connecting frame through a groove, and the partition plate and the connecting frame are tightly fitted together.
[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] 1. This utility model, through the setting of a connecting frame, threaded hole, filter screen and threaded rod, installs a connecting frame at the pipe connection position. The filter screen is installed and fixed inside the connecting frame by the threaded rod. This can isolate the position where the submersible sewage pump is connected to the pipe, making it easier to clean the submersible sewage pump and preventing blockage.
[0012] 2. This utility model, through the setting of a connecting frame, a sliding groove, a sealing cover, a fastening rod, and a partition plate, allows the partition plate installed in the device to be adjusted through the sliding groove opened inside the connecting frame by the sealing cover. This allows the entire connecting frame to be partitioned when the device is in use, thus isolating sewage at the connection point and facilitating the inspection and maintenance of the entire sewage pipe.
[0013] 3. This utility model, through the setting of a connecting frame, connector and limiting hole, and the connector with multiple sets of limiting holes at both ends of the device, can better connect to the sewage pipe through the limiting holes when connecting to the pipeline, and ensure the stability of the connection.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0020] The embodiments of this utility model will be described below based on its overall structure.
[0021] Please see Figure 1-4 A pipe connection device for a submersible sewage pump includes a connecting frame 1. Connectors 2 are installed at both the front and rear ends of the connecting frame 1. Limiting holes 3 are formed on the surface of the connecting heads 2, arranged in a circular array around the connecting heads 2. The connecting heads 2 are symmetrically arranged about the central axis of the connecting frame 1. The multiple sets of limiting holes 3 better ensure the stability and sealing of the connection during connection. A threaded hole 4 is formed inside the connecting frame 1. A filter screen 5 is installed inside the connecting frame 1. Threaded rods 6 are installed at both ends of the filter screen 5. The filter screen 5 is threadedly connected to the connecting frame 1, and the filter screen 5 is arranged about the central axis of the connecting frame 1. The axis is symmetrically set. The filter screen 5 installed in the device can block the connection between the submersible sewage pump and the pipeline, which can prevent the pipeline from getting blocked during use. The inner wall of the connecting frame 1 has a sliding groove 7. A sealing cover 8 is installed at the upper end of the connecting frame 1. A fastening rod 9 is installed at the outer end of the sealing cover 8. A partition plate 10 is installed at the lower end of the sealing cover 8. The partition plate 10 forms a sliding structure with the connecting frame 1 through the sliding groove 7, and the partition plate 10 fits tightly with the connecting frame 1. The partition plate 10 installed in the device can be adjusted through the sliding groove 7 opened in the inner wall of the connecting frame 1, which can block the entire connecting frame 1.
[0022] Working principle: During use, one end of the device can be connected to the submersible sewage pump through the connectors 2 installed at both ends, and the other end of the connector 2 can be connected to the pipeline. During connection, multiple sets of limiting holes 3 can be used to achieve better connection and sealing. After the connection is completed, a corresponding filter screen 5 is installed on the inner wall of the connecting frame 1. This can block debris during the use of the submersible sewage pump and prevent clogging. After the submersible sewage pump is finished using the device, the connecting frame 1 can be divided in the middle by adjusting the sliding groove 7 opened in the inner wall of the connecting frame 1 through the partition plate 10. After the division, the internal filter screen 5 can be disassembled and cleaned for easy maintenance and replacement, ensuring the efficiency of the submersible sewage pump. This completes the use of the device. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
