Description

Technical Field

[0001] The utility model relates to the field of drainage structures, in particular to a drainage structure for municipal engineering. Background Art

[0002] At present, a Chinese utility model with announcement number CN219471159U discloses a drainage structure for municipal engineering, including a sewer, a drainage pipe, a filter box, a transition cylinder and a pipe, wherein the drainage pipe is connected to the side wall of the sewer, the filter box is placed in the sewer, the filter box is located at the lower side of the drainage pipe, the transition cylinder is frustoconical, the diameter of the upper end of the transition cylinder is larger than the diameter of the lower end, the transition cylinder is located above the drainage pipe, the top of the outer wall of the transition cylinder contacts the inner wall of the sewer, the bottom end of the transition cylinder is connected to the pipe, the bottom end of the pipe is connected to the top wall of the filter box, the top wall of the filter box is provided with a plurality of sieve holes, a plurality of hooks are connected to the transition cylinder, the inner wall of the sewer is provided with a plurality of grooves, and the plurality of grooves are distributed longitudinally. This structure can filter out debris to reduce the blockage of urban drainage pipes.

[0003] Although the existing drainage structure can filter out debris, there are still other problems during use. For example, it is inconvenient to collect and clean impurities. After falling into the well, the impurities will fall directly to the bottom of the well. Since the bottom of the well is deep, personnel need to go deep to clean it, which increases the cleaning burden of personnel. In addition, it does not have the function of isolating odors. In the hot summer environment, sewage is often accompanied by pungent odors. The odors in the sewage will enter the well through the pipe and radiate upward, causing a certain impact on the surrounding environment. In order to solve the above-mentioned problems, we propose a drainage structure for municipal engineering. Utility Model Content

[0004] The utility model aims to provide a drainage structure for municipal engineering, which solves the problem that the existing drainage structure is inconvenient for collecting and cleaning impurities and has no odor isolation function.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: a drainage structure for municipal engineering, comprising a drainage well, a drainage pipe is installed through the surface of the drainage well, a fixed sleeve is installed on the surface of the drainage well, a collecting cylinder is arranged inside the drainage well, liquid outlet holes are provided on the bottom and surface of the collecting cylinder, a limiting ring plate is fixedly sleeved on the surface of the collecting cylinder, the limiting ring plate is placed on the top of the drainage well, a well cover is placed on the top of the limiting ring plate, a fixed frame is installed inside the drainage well, a first fixed rod is welded inside the fixed frame, a rotating sleeve is rotatably sleeved on the surface of the first fixed rod, and a rotating plate is equidistantly welded on the surface of the rotating sleeve.

[0006] The above technical solution can facilitate the collection and cleaning of impurities, is simple and labor-saving to operate, and improves the cleaning efficiency of personnel. At the same time, it can have the function of odor isolation to prevent the odor in sewage from continuously emitting upwards, thereby improving the surrounding environment.

[0007] The utility model is further configured as follows: a buffer pad is installed on the top of the limiting ring plate.

[0008] By adopting the above technical solution and providing a buffer pad, the limiting ring plate can be protected, thereby reducing the impact force generated when the manhole cover is dropped.

[0009] The utility model is further configured as follows: a second fixing rod is welded inside the collecting tube, a pulling plate is welded at the other end of the second fixing rod, and the top end of the pulling plate is conical.

[0010] By adopting the above technical solution, through the provision of the second fixing rod and the pulling plate, it is convenient for personnel to hold the pulling plate and pull out the collecting tube after the manhole cover is taken out.

[0011] The utility model is further configured as follows: a mounting hole is provided inside the fixing frame.

[0012] By adopting the above technical solution and setting the mounting holes, it is convenient for personnel to fix the fixing frame to the inner wall of the drainage well with screws.

[0013] The utility model is further configured as follows: a liquid guide frame is installed on the top of the fixed frame.

[0014] By adopting the above technical solution, the sewage on the top of the fixed frame can be guided by setting the liquid guide frame, so that the sewage on the fixed frame can quickly flow into the fixed frame.

[0015] The utility model is further configured as follows: the collecting tube and the limiting ring plate are both made of stainless steel.

[0016] By adopting the above technical solution, the collecting tube and the limiting ring plate have the characteristics of high strength, low density and excellent corrosion resistance.

[0017] In summary, the utility model has the following beneficial effects:

[0018] 1. The utility model allows the impurity-containing sewage to flow into the drainage well from the upper manhole cover, and the impurity-containing sewage entering the drainage well will first fall into the collecting cylinder, which can intercept the impurities in the sewage so that they cannot fall, and the sewage will flow out through the liquid outlet and continue to fall, and the sewage that falls to the bottom will flow out through the drainage pipe. When there are too many impurities in the collecting cylinder, the manhole cover will be lifted up first, and the pressure on the limiting ring plate will be released after the manhole cover is lifted out, and finally the pulling plate can be grasped to bring the collecting cylinder out, which can facilitate the collection and cleaning of impurities, is simple and labor-saving to operate, and improves the cleaning efficiency of personnel.

[0019] 2. In the utility model, sewage flowing out of the collecting tube will pass through the fixed frame when falling. After falling into the fixed frame, the sewage will flow onto the rotating plate. When the rotating plate is impacted by the sewage, it will drive the rotating sleeve to rotate. When the rotating plate is in the rotating state, the sewage will flow down from top to bottom. When there is no foreign object touching the surface of the rotating plate, it will be in a static state. The rotating plate in the static state will cooperate with the fixed frame to play an isolating role, and can have the function of isolating odor, thereby preventing the odor in the sewage from continuously emitting upward, and improving the surrounding environment.
