Description

Technical Field

[0001] This utility model relates to the field of drainage pipe technology, and in particular to a municipal drainage pipe. Background Technology

[0002] Municipal drainage pipes refer to the rainwater and sewage pipes under municipal roads, commonly known as "sewage pipes," and are usually called municipal drainage pipes in engineering. Based on the current state of infrastructure under municipal roads in China, various pipelines are generally installed, such as power, communication, gas, water supply, and drainage pipes. Because drainage pipes take into account measures for separating rainwater and sewage—rainwater is generally discharged into nearby rivers, while sewage is discharged elsewhere—municipal drainage pipes include both rainwater and sewage pipes.

[0003] Publication (Announcement) No. CN221760859U discloses a municipal drainage pipe, including a pipe body. A filter bucket is provided on the left side of the inner surface of the pipe body, and an anti-clogging display mechanism is provided on the right side of the filter bucket. The anti-clogging display mechanism includes a fixed rod, which is fixedly installed in the middle of the right side surface of the filter bucket. An inclined block is fixedly connected to the right side of the fixed rod. This application utilizes a movable filter bucket installed inside the pipe body. When the filter bucket is blocked, the force of the water flow will drive the filter bucket to move towards the inside of the pipe body, thereby driving the inclined block to move towards the inside of the pipe body. With the cooperation of the roller and the inclined surface of the inclined block, the movable rod is continuously raised, causing the height of the indicator block to rise. Thus, when the staff checks the location of the blockage, they can find the blocked pipe by observing the position of the indicator block, saving working time and improving the efficiency of troubleshooting and cleaning maintenance.

[0004] While the above solution makes it convenient to check the location of the blockage, the blockage indicator component is fixed to the drain pipe and is difficult to disassemble and maintain. Therefore, we propose a municipal drain pipe. Utility Model Content

[0005] The main purpose of this utility model is to provide a municipal drainage pipe that solves the problem of difficult disassembly and maintenance of the blockage indicator component fixed on the drainage pipe by setting a detection unit and cleaning components.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a municipal drainage pipe, including a drainage pipe body, and further including: a detection unit and a cleaning component installed on the drainage pipe body; The detection unit includes a transparent observation tube, a closed end cap, a sliding rod, a limiting block, and a floating disk. The transparent observation tube is fixedly installed on the outer circumferential surface of the top of the main body of the drain pipe. The closed end cap is threadedly fitted onto the outer circumferential surface of the top of the transparent observation tube. The sliding rod is fixedly installed at the center of the top surface inside the closed end cap and extends into the main body of the drain pipe. The limiting block is fixedly installed at the bottom end of the sliding rod. The floating disk is movably sleeved on the outer circumferential surface of the sliding rod and located inside the transparent observation tube. The cleaning assembly includes a support column, an annular brush, support springs, positioning rods, and a pull block. The support column is fixedly installed at the center of the top surface of the closed end cap. Two storage holes are symmetrically opened on the outer circumferential surface of the top of the support column. The annular brush is movably sleeved on the outer circumferential surface of the top of the support column, and two positioning holes are symmetrically opened on the inner wall of the annular brush. The two support springs are respectively fixedly installed in the two storage holes. The two positioning rods are respectively fixedly installed on the end faces of the two support springs and extend into the positioning holes. A strip groove communicating with the storage holes is opened on the top surface of the support column. The pull block is fixedly installed on the outer circumferential surface of the support column and extends to the outside of the support column through the strip groove.

[0007] Preferably, both ends of the drain pipe body are fixedly provided with connecting rings.

[0008] Preferably, the transparent observation tube and the main body of the drain pipe are arranged perpendicular to each other.

[0009] Preferably, a plurality of actuating levers are fixedly arranged at equal intervals on the outer circumferential surface of the closed end cap.

[0010] Preferably, the pull block and the positioning rod are arranged in a one-to-one correspondence.

[0011] Preferably, the positioning rod and the support column are arranged perpendicular to each other.

[0012] Compared with the prior art, the municipal drainage pipe of this utility model has the following beneficial effects: 1. In this utility model, by setting a detection unit, while the closed end cap is threaded onto the outer circumferential surface of the top of the transparent observation tube, the slide rod fixedly set in the center of the top surface inside the closed end cap is put into the drain pipe body. The floating plate, which is movably sleeved on the outer circumferential surface of the slide rod, will rise and fall above the limiting block with the rise and fall of the water level inside the drain pipe body. After the water level inside the drain pipe body is blocked and rises continuously, the floating plate can be lifted into the transparent observation tube for external personnel to observe and judge. After removing the closed end cap, the floating plate can be cleaned and maintained. The equipment is simple and labor-saving to disassemble and assemble the blockage indicator component.

[0013] 2. In this utility model, by setting up a cleaning component, after the positioning rod is retracted to the storage hole on the outer circumferential surface of the top of the support column by the pull block, the support spring in the storage hole is compressed accordingly. The annular brush can be movably sleeved on the outer circumferential surface of the top of the support column without obstruction. After the pull block is released, the deformation of the support spring returns to normal, which can push the positioning rod into the positioning hole on the inner wall of the annular brush. The annular brush is then fixed on the support column. The support column and annular brush on the top surface of the closed end cover can be inserted into the transparent observation tube to clean the transparent observation tube by brushing, ensuring the marking and observation effect of the floating disk. The equipment is simple and flexible for cleaning and maintaining the blocked marking components. Attached Figure Description
