[0032] refer to Figures 1 to 3 A water-sealed inspection well according to an embodiment of the utility model is described.

[0033] like Figures 1 to 3As shown, the water seal inspection well includes a well body 100: a flow trough 200, which is arranged in the well body 100 and has a water seal line 210; a main water inlet pipe 300, which is arranged on the well wall of the well body 100; a main water outlet pipe 400, which is arranged on the well wall of the well body 100, and the main water inlet pipe 300 is coaxially arranged with the main water outlet pipe 400; a connecting branch pipe 500, which is arranged on the well wall of the well body 100, and the output end of the connecting branch pipe 500 extends downward to below the water seal line 210.

[0034] like Figure 1 As shown, the road extends in the left-right direction, and the street-facing buildings are respectively arranged on the front and rear sides of the road. The cross-section of the well body 100 is rectangular, and its length direction is consistent with the extension direction of the road. A flow trough 200 is provided at the bottom of the well body 100, and the flow trough 200 contains water for water sealing, and the liquid level of the water body is the water seal line 210. The main pipe water inlet pipe 300 is arranged at the left end of the well body 100, and the main pipe water outlet pipe 400 is arranged at the right end of the well body 100. The main pipe water inlet pipe 300 is connected to the main pipe water outlet pipe 400 through the buffer tank 240. The connecting branch pipe 500 is arranged at the rear end of the well body 100, and the connecting branch pipe 500 horizontally penetrates the well wall from the rear end of the well body 100, and then extends downward to below the water seal line 210. Therefore, when residents' household pipes are directly connected to the road sewage pipe system, the connecting branch pipe 500 can be water-sealed in the well body 100 to prevent the odor in the road sewage pipe from escaping to the residents' homes through the branch pipe and causing indoor environmental pollution, thereby providing a healthier, more comfortable and safer living environment.

[0035] In this specific embodiment, the flow trough 200 is symmetrically arranged with respect to the connecting branch pipe 500 , and the horizontal extension direction of the connecting branch pipe 500 is perpendicular to the extension direction of the main pipe water inlet pipe 300 .

[0036] In some specific embodiments of the present invention, a silt well 220 is provided in the flow channel 200, and the output end of the connecting branch pipe 500 is located in the silt well 220, and the silt well 220 is used to collect sewage sediment. Figure 1 and Figure 2 As shown, a silt well 220 extending in the front-to-back direction is opened in the flow channel 200, the silt well 220 is filled with water, and the water seal line 210 is flush with the top of the silt well 220. The connecting branch pipe 500 penetrates the well wall of the well body 100 from the back to the front, and then extends downward to the silt well 220 to achieve a water seal for the connecting branch pipe 500.

[0037] In some specific embodiments of the present invention, the bottom elevation of the flow trough 200 is the same as the top elevation of the silt pit 220 .

[0038] In some specific embodiments of the present invention, a guide slope 221 is provided at the bottom of the silt pit 220, and the guide slope 221 is inclined downward in a direction away from the connecting branch pipe 500. Figure 3 As shown, a guide slope 221 is provided at the bottom of the silt pit 220 along the front-to-back direction, and the guide slope 221 gradually slopes downward from the back to the front, that is, the height of the rear end of the guide slope 221 near the outlet end of the connecting branch pipe 500 is higher than the height of the front end of the guide slope 221 away from the outlet end of the connecting branch pipe 500. It should be noted that after the sewage is collected by the connecting branch pipe 500, it flows out from the outlet end of the connecting branch pipe 500, and the outflowing sewage flushes the silt pit 220, and at the same time, the sewage sediment is flushed to the low-lying area at the bottom of the silt pit 220, so as to facilitate the subsequent unified cleaning of the sewage sediment.

[0039] In some specific embodiments of the utility model, the flow channel 200 includes: a guide groove 230, which is arranged in the well body 100, the guide groove 230 is connected to the connecting branch pipe 500, and the cross-sectional area of ​​the guide groove 230 gradually increases in the direction away from the connecting branch pipe 500; a buffer groove 240, the buffer groove 240 is arranged in the well body 100, the buffer groove 240 is connected to the guide groove 230, the buffer groove 240 is located at the opposite end of the guide groove 230 and the connecting branch pipe 500, the buffer groove 240 is connected to the water outlet end of the main pipe inlet pipe 300, and the buffer groove 240 is connected to the water inlet end in the main pipe outlet pipe 400.

[0040] like Figure 1 As shown, the guide groove 230 and the buffer groove 240 are arranged in sequence from the back to the front, the connecting branch pipe 500 is connected to the guide groove 230, and the buffer groove 240 is located between the main pipe water inlet pipe 300 and the main pipe water outlet pipe 400, and is connected to the main pipe water inlet pipe 300 and the main pipe water outlet pipe 400. Specifically, as Figure 1 As shown, the cross section of the guide groove 230 along the horizontal direction is trapezoidal, that is, the cross-sectional area of ​​the rear end of the guide groove 230 gradually increases in the direction away from the connecting branch pipe 500. When water enters the flow groove 200 from the connecting branch pipe 500, due to the gradual increase in the cross-sectional area, the water flow is relatively wide and the flow rate is slowed down, which helps to balance the distribution of the water flow, avoid the situation where the local water flow is too large or too small, and improve the stability and balance of the entire flow groove 200 system. In this specific embodiment, the two sides of the guide groove 230 are side walls with a straight line guiding function. Of course, the side walls at the left and right ends of the guide groove 230 can also be arc walls with a curved guiding function.

[0041] In some specific embodiments of the utility model, the bottom elevation of the flow trough 200 is the same as the bottom elevation of the main pipe water inlet pipe 300, and the bottom elevation of the flow trough 200 is the same as the bottom elevation of the main pipe water outlet pipe 400. It should be noted that the design of the flow trough 200 is intended to achieve water diversion and distribution, ensuring that water flows evenly from the main pipe water inlet pipe 300 into the flow trough 200. In order to achieve horizontal diversion, it is necessary to maintain horizontal connectivity between the main pipe water inlet pipe 300, the main pipe water outlet pipe 400 and the flow trough 200. By keeping their bottom elevations consistent, it can be ensured that water can flow freely between them without encountering obstacles or uneven flow. Therefore, when water enters the flow trough 200 from the main pipe water inlet pipe 300, the height of the water surface remains consistent, and the water flow will not be subject to additional disturbances or changes, which helps to keep the water flow in the flow trough 200 stable and prevent the occurrence of surges or turbulence.

[0042] In some specific embodiments of the present invention, an inspection well cover 600 is also included. The inspection well cover 600 is arranged on the top of the well body 100. The inspection well cover 600 is used to facilitate inspection, maintenance, repair and cleaning work by the staff.

[0043] like Figure 3 As shown, an inspection well cover 600 is provided on the top of the well body 100. Specifically, the inspection well cover 600 is located above the silt well 220. In the present specific embodiment, the inspection well cover 600 is located directly above the low-lying part of the silt well 220. Therefore, when the inspection workers are performing cleaning work, they can go down the well from the inspection well cover 600 to reach the place where the sewage sediments are gathered.

[0044] Furthermore, if Figure 1 As shown, the left and right sides of the rear end of the top of the flow chute 200 are respectively triangular platforms, and the front end of the top of the flow chute 200 is a long strip platform. When the inspection workers go down the well from the inspection well cover 600, they can land on the three platforms, thereby avoiding the inspection workers from stepping directly into the silt well 220, reducing the workload of the inspection workers.

[0045] In some specific embodiments of the present invention, the connecting branch pipe 500 includes a horizontal pipe section 510 and a vertical pipe section 520, and the horizontal pipe section 510 and the vertical pipe section 520 are connected by a right-angle elbow 530 to realize the layout of the pipeline system in a limited space. Figure 3As shown, the horizontal pipe section 510 extends in the front-to-back direction, and the vertical pipe section 520 extends in the up-down direction. The horizontal pipe section 510 and the vertical pipe section 520 are connected by a right-angle elbow 530. On the one hand, the right-angle elbow 530 changes the sewage flow direction of the connecting branch pipe 500. On the other hand, the right-angle elbow 530 can realize the layout of the pipeline system in a limited space. Specifically, since its turning angle is 90°, it can make the pipeline turn in a smaller area, thereby saving space to adapt to the construction environment that needs to install the pipeline system in a narrow or crowded environment.

[0046] It should be noted that the water seal layer needs a certain water depth to effectively prevent the backflow of gas. When the water outlet or drain outlet is very close to the water surface, the water pressure is low, the stability of the water seal layer will be affected, and the risk of water seal failure will increase. On the other hand, when the water outlet or drain outlet is too close to the water surface, the water seal layer is easily affected by evaporation, especially in a dry environment or low water level conditions. The dried water seal layer will not be able to prevent the backflow of gas, allowing malodorous gas to enter the room. Therefore, in some specific embodiments of the utility model, the distance between the output end of the connecting branch pipe 500 and the water seal line 210 is greater than 0.25m.

[0047] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
