Description

Technical Field

[0001] The utility model relates to the technical field of drainage and sewage pipes, and particularly relates to a municipal drainage and sewage pipe. Background Art

[0002] Municipal drainage pipes refer to rainwater and sewage pipes under municipal roads, that is, the so-called "sewer pipes", which are usually called municipal drainage pipes in engineering. Generally, different pipelines are set, such as power, communication, gas, water supply, drainage pipes, etc. And due to the consideration of rain and sewage diversion measures for drainage pipes, that is, rainwater is generally discharged into rivers nearby, and sewage is discharged into sewage treatment plants, so municipal drainage pipes include two types of pipes: rainwater and sewage.

[0003] The existing drainage and sewage pipes do not have an anti-blocking effect. After long-term use, the drainage and sewage pipes are prone to blockage, resulting in a reduction in drainage and sewage effects, which is not conducive to the progress of municipal drainage work. Therefore, it is necessary to provide a municipal drainage and sewage pipe. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a municipal drainage and sewage pipe, which can effectively solve the problem that the existing drainage and sewage pipes in the background art do not have an anti-blocking effect, are prone to blockage after long-term use, resulting in a reduction in drainage and sewage effects, and are not conducive to the progress of municipal drainage work.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is: a municipal drainage and sewage pipe, including a pipe unit, a positioning unit fixedly connected to the inner wall surface of the pipe unit, and an anti-blocking unit installed inside the pipe unit, and further including a fastening unit arranged inside the anti-blocking unit;

[0006] The fastening unit includes an adjusting shaft movably penetrating through the center of the top of the anti-blocking unit, and two positioning clamping rods movably arranged inside the anti-blocking unit for fixedly installing the anti-blocking unit.

[0007] Preferably, the pipe unit includes a drain pipe, a side flow pipe embedded on one side of the drain pipe, and a threaded plugging head threadedly connected to the bottom end of the drain pipe.

[0008] Preferably, the positioning unit includes two positioning blocks fixedly connected to the opposite inner wall surfaces of the drain pipe, and positioning card holes respectively opened on the inner sides of the two positioning blocks.

[0009] Preferably, the anti-blocking unit includes an annular top plate installed on the tops of the two positioning blocks, a filter screen frame fixedly connected to the bottom of the annular top plate, a hollow opening opened on the top of the annular top plate, and through holes opened on both sides of the filter screen frame.

[0010] Preferably, the fastening unit further includes a transverse bevel gear sleeved on the outer surface of the adjusting shaft, two lead screws movably arranged on the opposite inner wall surfaces of the hollow opening, vertical bevel gears respectively fixedly connected to one ends of the two lead screws, and thread blocks respectively threadedly connected to the outer surfaces of the two lead screws.

[0011] Preferably, the transverse bevel gear is meshed with the two vertical bevel gears, one ends of the two positioning rods are respectively fixedly connected to the bottoms of the two thread blocks, the outer diameter dimension of the positioning rod is smaller than the inner diameter dimension of the through hole, and the outer diameter dimension of the positioning rod is adapted to the inner diameter dimension of the positioning hole.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] In the utility model, by placing the annular top plate on the tops of the two positioning blocks, and then rotating the adjusting shaft, the adjusting shaft drives the transverse bevel gear to rotate. The rotation of the transverse bevel gear drives the two lead screws to rotate synchronously inside the hollow opening through the meshing with the two vertical bevel gears. The synchronous rotation of the two lead screws drives the two thread blocks to move synchronously on their outer surfaces and move away from each other. The mutual separation of the two thread blocks drives the two positioning rods to move synchronously and move away from each other, so that the two positioning rods respectively pass through the through holes and enter the inside of the positioning holes of the two positioning blocks, thereby completing the installation of the filter screen frame. Through the setting of the filter screen frame, the impurities entering the drain pipe can be centrally collected, avoiding the blockage of the drain pipe. Through the setting of the threaded plug head, it is convenient to clean the fine gravel. Through the height difference between the side flow pipe and the drain pipe, it is convenient for the fine gravel to accumulate, avoiding blockage, and the filter screen frame can be quickly disassembled and assembled, which is convenient for cleaning the filtered impurities in time, improving the practicability of the drain pipe.

By setting the threaded plug 103, it is convenient to clean fine sand and gravel. By setting a height difference between the side flow pipe 102 and the drain pipe 101, it is convenient for the accumulation of fine sand and gravel to avoid blockage.

[0025] As Figure 1 and Figure 3 shown, the positioning unit 200 includes two positioning blocks 201 fixedly connected to the opposite inner wall surfaces of the drain pipe 101, and positioning card holes 202 respectively opened on the inner sides of the two positioning blocks 201.

The fastening unit 400 further includes a transverse bevel gear 402 sleeved on the outer surface of the adjustment shaft 401, two lead screws 403 movably arranged on the opposite inner wall surfaces of the hollow opening 303, vertical bevel gears 404 respectively fixedly connected to one ends of the two lead screws 403, and threaded blocks 405 respectively threadedly connected to the outer surfaces of the two lead screws 403. The transverse bevel gear 402 is meshed with the two vertical bevel gears 404. One ends of the two positioning rods 406 are respectively fixedly connected to the bottoms of the two threaded blocks 405. The outer diameter of the positioning rod 406 is smaller than the inner diameter of the through hole 304, and the outer diameter of the positioning rod 406 is adapted to the inner diameter of the positioning hole 202.

[0028] Working principle: By placing the annular top plate 301 on the tops of the two positioning blocks 201, and then rotating the adjustment shaft 401, the adjustment shaft 401 drives the transverse bevel gear 402 to rotate. The rotation of the transverse bevel gear 402 drives the two lead screws 403 to rotate synchronously inside the hollow opening 303 through meshing with the two vertical bevel gears 404. The synchronous rotation of the two lead screws 403 drives the two threaded blocks 405 to move synchronously on their outer surfaces and move away from each other. The mutual separation of the two threaded blocks 405 drives the two positioning rods 406 to move synchronously and move away from each other, so that the two positioning rods 406 respectively pass through the through holes 304 and enter the inside of the positioning holes 202 of the two positioning blocks 201, thus completing the installation of the filter screen frame 302. Through the setting of the filter screen frame 302, the impurities entering the inside of the drain pipe 101 can be centrally collected, avoiding the blockage of the drain pipe 101. Through the setting of the threaded plug 103, the cleaning of fine gravel can be facilitated. Through the height difference between the side flow pipe 102 and the drain pipe 101, the accumulation of fine gravel can be facilitated, avoiding blockage, and the filter screen frame 302 can be quickly disassembled and assembled, facilitating the timely cleaning of the filtered impurities, improving the practicability of the drain pipe 101.
