Abstract
Description
Technical Field
[0001] This utility model relates to the field of drainage pipeline technology, specifically to a municipal environmental protection drainage pipeline. Background Technology
[0002] Leaks in municipal drainage pipes are mainly caused by pipe aging, substandard construction quality, and environmental factors (such as soil corrosion and vehicle run-over). During the initial installation phase, proper connection and fixing of the pipes is a key technical aspect in solving the problem of sewage leakage. In existing technologies, flange connection at the pipe end is usually used for installation. Under normal water pressure, the problem of exposed sewage is not obvious. However, when the water pressure is too high, such as in cases of concentrated sewage discharge, heavy rainfall, or flooding, the existing connection method will result in exposed sewage, which cannot be discharged smoothly to reduce water pollution. Secondly, in order to increase the sealing of the flange connection at the pipe ends and prevent the problem of exposed sewage, a sealing element, such as a gasket, is added between the two connecting flanges to form a sealing installation for the two pipes. However, this type of structure does not provide good stability for the installation of the two pipes and is also prone to leakage and sewage exposure.
[0003] Therefore, there is a need to provide a municipal environmentally friendly drainage pipe. Utility Model Content
[0004] In view of the problems existing in the prior art, this utility model provides a municipal environmentally friendly drainage pipe, aiming to improve and solve the technical problems mentioned above.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a municipal environmental protection drainage pipe, comprising a filter tank, a fixed pipe, and a drainage pipe. The fixed pipe is distributed and connected to both sides of the filter tank. The drainage pipe is installed at the outlet end of the fixed pipe. Flange plate one is fixedly connected to both ends of the drainage pipe, and flange plate two is fixedly connected to the outlet end of the fixed pipe. Installation slots are evenly distributed around the circumference of flange plate one and flange plate two, located on surfaces of flange plate one and flange plate two that are far apart from each other. Fixing blocks are installed within the installation slots, and two opposing fixing blocks are fixed together by bolts, with the bolts penetrating both flange plate one and flange plate two. Second, by fixing two fixing blocks, flange plate one and flange plate two are fixedly connected. Fixing plate three is set on both sides of the drainage pipe and on the surface near flange plate one. Fixing plate four is set on the surface of the fixed pipe near flange plate two. Slots two are evenly opened on the surfaces of fixing plate three and fixing plate four that are far apart from each other. The number of slots two corresponds to the number of installation slots and they are coaxially set. Reinforcing ribs are inserted and installed between slots two on both sides. The two ends of the reinforcing ribs are fixedly connected to slots two by bolts. Long threaded holes are symmetrically opened in the middle of the reinforcing ribs. Threaded rods are fixedly connected to the top of the fixing blocks. The threaded rods pass through the long threaded holes and are fixedly connected to the threaded rods by nuts.
[0006] Specifically, the filter tank is used to filter incoming wastewater, which is then transported to the drainage pipe via a fixed pipeline. To prevent leakage at the connection between the fixed and drainage pipes, flange plate one is fixedly connected to both ends of the drainage pipe, and flange plate two is fixedly connected to the outlet end of the fixed pipe. Installation slots are provided at the far ends of flange plate one and flange plate two, and fixing blocks are installed inside the installation slots. The two fixing blocks are connected by bolts, which pass through threaded holes in the installation slots, achieving a sealed installation between flange plate one and flange plate two. The fixing blocks further ensure a secure and sealed installation of flange plate one and flange plate two. A threaded rod is installed on the top of the fixing block. A fixing plate three is installed on the surface of the drainage pipe near flange plate one, and a fixing plate four is installed on the surface of the fixed pipe near flange plate two. Slots two are opened on the surfaces of fixing plates three and four. A reinforcing rib plate is inserted and installed between slots two. The connection between the fixed pipe and the drainage pipe is reinforced by the reinforcing rib plate, which further strengthens the installation of the fixed pipe and the drainage pipe. By symmetrically opening long threaded holes in the middle of the reinforcing rib plate, the threaded rod passes through the long threaded holes and is fixedly connected by a nut, thus realizing the fixed installation of the reinforcing rib plate and the fixing block. The fixing block is installed between the fixed pipe and the drainage pipe, which prevents leakage at the connection between the fixed pipe and the drainage pipe.
[0007] Preferably, the outlet end of the fixed pipe has the same structure as the outlet end of the drainage pipe. The outlet end of the drainage pipe is provided with a sealed inner pipe, and the inlet end of the drainage pipe is provided with a plug-in inner pipe. The plug-in inner pipe is coaxial with and connected to the drainage pipe. The plug-in inner pipe is plugged into the drainage pipe and installed between the sealed inner pipe, and is installed on the outside of the plug-in inner pipe through the sealing inner pipe sleeve.
[0008] By setting the outlet end of the fixed pipe to have the same structure as the outlet end of the drainage pipe, a sealed inner pipe is installed on the outside of the plug-in inner pipe, realizing a sealed sleeve installation between the pipes. This solves the leakage problem caused by the flange installation in the existing technology and improves the sealing of the pipe connection installation.
[0009] Preferably, in order to further achieve a sealed installation between pipes, a sealing ring is provided on the outer surface of the inner sealing pipe. The sealing ring is sealed to the inner wall of the inner pipe, thereby achieving a sealed installation between the inner and outer pipes and further improving the sealing connection at the pipe installation joint.
[0010] Preferably, in order to improve the fixed sealing installation at the pipe connection, three mounting slots are evenly opened around the circumference of flange plate one and flange plate two. This achieves fixed installation while reducing the number of mounting slots, simplifying the installation process, and improving installation efficiency.
[0011] Preferably, in order to further strengthen the fixed sealing at the pipe connection, three slots are evenly provided on the surfaces of the fixed plate three and the fixed plate four that are far apart from each other. The two slots two in the axial direction are fixedly connected to the reinforcing rib plate to achieve the fixed sealing installation at the pipe connection.
[0012] In summary, this utility model provides a municipal environmentally friendly drainage pipe, and the beneficial effects achieved by the technical solution adopted in this patent are as follows: By using slots 2 on the surfaces of fixing plates 3 and 4, and inserting reinforcing ribs between slots 2, the connection between the fixed pipe and the drainage pipe is further reinforced by the reinforcing ribs. By symmetrically opening elongated screw holes in the middle of the reinforcing ribs, threaded rods pass through the elongated screw holes and are fixedly connected by nuts, the reinforcing ribs and fixing blocks are fixedly installed, further reinforcing the fixing blocks installed between the fixed pipe and the drainage pipe, thus preventing leakage at the connection between the fixed pipe and the drainage pipe.
[0013] By setting the outlet end of the fixed pipe to have the same structure as the outlet end of the drainage pipe, a sealed inner pipe is installed on the outside of the plug-in inner pipe, realizing a sealed sleeve installation between the pipes. This solves the leakage problem caused by the flange installation in the existing technology and improves the sealing of the pipe connection installation. Attached Figure Description

The outlet end of the fixed pipe 2 and the outlet end of the drainage pipe 3 have the same structure, both using a sealed inner pipe 17 installed inside the pipe. The sealed inner pipe 17 is coaxially connected to the pipe, forming a insertion hole between the sealed inner pipe 17 and the pipe. The inlet end of the drainage pipe 3 is configured as an insertion inner pipe 21, which is inserted into the insertion hole and sealed with the sealed inner pipe 17. The ends of the drainage pipe 3 are... Flange plate 4 is set as flange plate 1, and flange plate 5 is set as the outlet end of fixed pipe 2.
