Technical Field

[0001] The utility model relates to the technical field of urban drainage, in particular to a drainage structure which is not easily blocked. Background Art

[0002] The urban drainage system is an engineering facility system for treating and draining urban sewage and rainwater. It is an integral part of urban public facilities. The urban drainage system planning is an integral part of the city's overall planning. The urban drainage system is usually composed of drainage pipes and sewage treatment plants. When the sewage and rainwater diversion system is implemented, sewage is collected by drainage pipes, sent to sewage treatment, and then discharged into water bodies or recycled; rainwater runoff is collected by drainage pipes and discharged into nearby water bodies.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-Figure 3 , this embodiment provides a drainage structure that is not easy to be blocked, and the drainage structure that is not easy to be blocked includes:

[0026] A drainage well 1, wherein a drainage structure is provided inside the drainage well 1, and the drainage structure is used to achieve solid-liquid separation in sewage;

[0027] A separation structure, which is fixedly installed inside the drainage well 1 and is used to discharge solid impurities in sewage and avoid clogging of the drainage structure;

[0028] Compared with the prior art, by setting up a separation structure and a drainage structure to form a coordination, the sewage can be separated into solid and liquid, and the solid impurities and liquid sewage can be discharged separately at the same time, thereby improving the efficiency of sewage discharge and avoiding the drainage structure from being blocked in a short time.

[0029] See also Figure 1-Figure 2 In one embodiment, the drainage structure comprises:

[0030] A manhole cover 2, wherein the manhole cover 2 is fixedly mounted on the top of the drainage well 1, and a plurality of straight slots 3 are arranged in the middle of the manhole cover 2, and two adjacent straight slots 3 are arranged at equal distances;

[0031] A drainage pipe 4, wherein the drainage pipe 4 is fixedly installed inside the drainage well 1, and a filter screen 7 is arranged in the middle of the drainage pipe 4;

[0032] In order to avoid clogging of the drainage structure during use, when the sewage enters the drainage well 1 through the straight groove 3 in the middle of the manhole cover 2, the sewage flows downward along the path of the inclined plate 6. As the sewage flows, the filter holes 9 set on the side of the trash gate 8 can achieve solid-liquid separation of the sewage, and the sewage enters the trash gate 8 and enters the drain pipe 4 through the through hole 11, and is finally discharged through the drain pipe 4 through the filtering effect of the filter screen 7.

[0033] See also Figure 2-Figure 3 In one embodiment, the separation structure comprises:

[0034] The inclined plate 6 is in an inverted V-shaped structure, and a plurality of through holes 11 are provided in the middle of the inclined plate 6;

[0035] The trash gate 8 is fixedly mounted on the top of the inclined plate 6 and surrounds the through hole 11. A plurality of filter holes 9 are arranged on the side of the trash gate 8;

[0036] A sewage pipe 5, which is fixedly installed on both sides of the drainage well 1 and the inclined plate 6;

[0039] As the sewage enters the drainage well 1, the subsequent flow of sewage can pass the filtered impurities through the guide plate 12 and finally be discharged through the sewage pipe 5. As the sewage is continuously discharged, when the impurities accumulate, the impurities can be cut by the inertia of the water flow and the cooperation with the conical part 10 at the top of the trash gate 8, so that the impurities stuck at the position of the trash gate 8 can smoothly enter the guide plate 12 and finally be discharged from the sewage pipe 5. Through the mutual cooperation between the drainage structure and the separation structure, the drainage structure inside the drainage well 1 can be prevented from being blocked. The manhole cover 2 and the drainage well 1 are detachable structures, and the top of the inclined plate 6 can be cleaned regularly by humans.

As the sewage flows, the filter holes 9 set on the side of the trash gate 8 can achieve solid-liquid separation of the sewage, and the sewage enters the trash gate 8 and enters the drainage pipe 4 through the through hole 11, and is finally discharged through the drainage pipe 4 through the filtering effect of the filter screen 7. As the sewage enters the drainage well 1, the subsequent flow of sewage can remove the filtered impurities through The guide plate 12 is finally discharged through the sewage pipe 5. With the continuous discharge of sewage, when impurities accumulate, the impurities can be cut by the inertia of the water flow and the cooperation with the conical part 10 at the top of the trash gate 8, so that the impurities stuck at the position of the trash gate 8 can smoothly enter the guide plate 12 and finally be discharged from the sewage pipe 5. The mutual cooperation between the drainage structure and the separation structure can avoid the blockage of the drainage structure inside the drainage well 1. The manhole cover 2 and the drainage well 1 are detachable structures, and the top of the inclined plate 6 can be cleaned regularly by manual labor.
