Description

Technical Field

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

[0002] Municipal sewage pipes are an important part of urban infrastructure. They are responsible for collecting and transporting domestic sewage, industrial wastewater and other urban sewage to sewage treatment plants for treatment, and finally discharge them into natural water bodies or recycle them after meeting the discharge standards. The design, construction and maintenance of municipal sewage pipe systems play a vital role in protecting public health and preventing environmental pollution.

[0003] Existing sewage pipes are often clogged by foreign objects during use, resulting in poor drainage. Once a blockage occurs, the only option is to wait for the CCTV pipe inspection robot to clean and remove the blockage before continuing to drain. This method is limited by the pipe structure and cannot perform fast and effective emergency drainage, so the efficiency is relatively low.

[0004] In summary, a municipal sewage pipeline is needed to solve the deficiencies in the prior art. Utility Model Content

[0027] Embodiment 1:

[0028] like Figure 1 , 2 As shown in Figure 3, a municipal sewage pipe includes a sewage pipe body 1, and the sewage pipe body 1 includes an inner drainage pipe 2 and an outer drainage pipe 3. The inner drainage pipe 2 is arranged inside the outer drainage pipe 3. The inner drainage pipe 2 is used to discharge sewage under normal daily conditions, and the outer drainage pipe 3 is used for emergency drainage when blockage occurs inside the inner drainage pipe 2 and the drainage speed is significantly slowed down. A filtering mechanism 4 is provided between the inner drainage pipe 2 and the outer drainage pipe 3 for filtering foreign matter at the connection point.

[0029] The inner drainage pipe 2 is provided with a plurality of drain ports 21 for connecting with the outer drainage pipe 3 .

[0030] The drain port 21 is opened on the left and right curved surface walls of the inner drain pipe 2 near the top area, and the diameter of the drain port 21 near the inner drain pipe 2 is larger than the diameter of the end near the outer drain pipe 3.

[0031] The opening height of the drain port 21 near the inner drain pipe 2 is higher than the opening height near the outer drain pipe 3. The higher side of the drain port 21 near the inner drain pipe 2 can accelerate the water diversion and discharge rate.

[0032] The filter mechanism 4 includes a support frame 41 and a filter cover 42. The support frame 41 is connected to the internal drainage pipe 2. The filter cover 42 is connected to the internal drainage pipe 2 through the support frame 41, and the filter cover 42 is provided with a circular chamfer. The filter cover 42 with a circular chamfer design can reduce drainage obstruction to a certain extent.

[0033] The sewage pipe body 1 is provided with a plurality of supporting wing plates 7 for connecting and fixing the inner drainage pipe 2 and the outer drainage pipe 3 .

[0034] The supporting wing plate 7 includes a supporting plate 71, a connecting head 72 and an arc panel 73. The two ends of the supporting plate 71 are connected to the arc panel 73 through the connecting head 72. The arc panels 73 at the two ends of the supporting plate 71 are respectively fitted with the outer surface of the inner drainage pipe 2 and the inner wall of the outer drainage pipe 3, and the arc panel 73 is made of soft rubber material.

[0035] When in use, the support wing plate 7 composed of the support plate 71, the connecting head 72 and the arc panel 73 plays a supporting and fixing effect on the inner drainage pipe 2, and the support wing plates 7 are arranged at intervals on the arc wall in the middle and below the inner drainage pipe 2, so as to play a better supporting effect. In actual application, the inner drainage pipe 2 is blocked due to the accumulation of foreign matter, and the drainage is not smooth. When the water level exceeds two-thirds of the inner drainage pipe 2, the sewage passes through the filtering mechanism 4 and is passively drained along the several drain ports 21 opened on the inner drainage pipe 2, and the sewage in the inner drainage pipe 2 is diverted to the outer drainage pipe 3, and auxiliary emergency drainage is performed through the outer drainage pipe 3. In this way, emergency drainage can be automatically started when the inner drainage pipe 2 is blocked to a certain extent. The structural design is scientific and reasonable, and the pertinence is relatively strong.

[0036] Embodiment 2:

[0037] like Figure 4 , 5As shown, a municipal sewage pipe includes a sewage pipe body 1, an inner drainage pipe 2, an outer drainage pipe 3 and a sewage pumping system. The sewage pumping system includes a sewage pump 5, a drain pipe 6, a background control terminal and several water flow detection modules. The sewage pump 5 connects the inner drainage pipe 2 and the outer drainage pipe 3 through the drain pipe 6. The water flow detection module is installed in the inner drainage pipe 2. The sewage pump 5 and the water flow detection module are both electrically connected to the background control terminal.

[0038] The drain pipe 6 includes an input pipe 61 and an output pipe 62, both of which are soft pipe bodies. The input pipe 61 and the output pipe 62 are connected to the water inlet and the water outlet of the sewage pump 5 respectively, and a filter ball head 611 is provided at one end of the input pipe 61 away from the water inlet of the sewage pump 5, through which foreign matter inside the inner drain pipe 2 is filtered.

[0039] The water flow detection module is arranged in sections and installed on the inner drainage pipe 2. The water flow detection module detects the internal water flow speed of the inner drainage pipe 2 in real time and feeds back to the background control terminal. The staff confirms the relevant information through the background control terminal. When obvious blockage is detected or the water flow is obviously slowed down, the sewage pump 5 is controlled to start and input the sewage in the inner drainage pipe 2 into the outer drainage pipe 3, thereby achieving an active emergency drainage effect.

[0040] It should be noted that the preferred implementation methods of the utility model are given in the specification and drawings of the utility model. However, the utility model can be implemented in many different forms and is not limited to the implementation methods described in the specification. These implementation methods are not used as additional restrictions on the content of the utility model. The purpose of providing these implementation methods is to make the understanding of the disclosure of the utility model more thorough and comprehensive. In addition, the above-mentioned technical features continue to be combined with each other to form various implementation methods not listed above, which are all regarded as the scope of the description of the utility model; further, for ordinary technicians in this field, they can be improved or transformed according to the above description, and all these improvements and transformations should belong to the scope of protection of the claims attached to the utility model.
