Technical Field

[0001] The invention relates to a blocking capsule suitable for air-water pulse cleaning of a drainage pipeline. Background Art

[0002] At present, when municipal drainage pipes need to be cleaned, the inlet and outlet sides of the inspection wells on both sides need to be blocked by blocking capsules, and then manual cleaning is required. This method requires a lot of manpower and is difficult to clean. Summary of the invention

[0003] The purpose of the present invention is to make up for the deficiencies of the prior art and to provide a plugging capsule suitable for air-water pulse cleaning of drainage pipes.

[0004] The above purpose is achieved through the following technical solutions: A plugging capsule suitable for air-water pulse cleaning of drainage pipes, the capsule is an annular airbag structure, and a through-core tube is fixed at the center of the annular airbag structure; The annular airbag structure comprises two side bag skins, between which N layers of annular bag skins are fixed, and the N layers of annular airbag skins are concentrically arranged to form an N-1 layer of airbag space; A separate air nozzle for inflating and deflation is fixed at each layer of airbag space.

[0005] The blocking capsule is suitable for air-water pulse cleaning of drainage pipes, and the side capsule skin and the annular capsule skin are both rubber capsule skin structures.

[0006] The plugging capsule is suitable for air-water pulse cleaning of drainage pipes, and the through-tube is a cylindrical tube with flanges at both ends.

[0007] The plugging capsule is suitable for air-water pulse cleaning of drainage pipes, and the through-core tube is connected to the center of the annular airbag body through a plugging glue. Beneficial Effects

[0008] 1. The present invention adds a through-tube in the middle of the annular airbag body. The through-tube is a through-type DN100 steel pipe, so that the plugging airbag tightly wraps the steel pipe, and flanges are provided at both ends of the steel pipe as connecting joints for connecting the gas-water pulse input pipeline. In this way, the gas-water pulse cleaning technology can be used to clean the drainage pipeline while ensuring the plugging of the inlet and drainage sides of the inspection well. No manpower is required for cleaning, thereby improving the cleaning efficiency.

[0009] 2. The annular airbag body of the present invention has multiple layers of airbag space, and can be used to inflate airbag spaces of different layers for municipal drainage pipes of different diameters to achieve blocking. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0011] Reference Figure 1-Figure 4 , a plugging capsule suitable for air-water pulse cleaning of drainage pipes, the capsule is an annular airbag body 3 structure, and a through-tube 2 is fixed at the center of the annular airbag body structure; By setting an annular airbag structure and a through-tube, which is a hollow tube, flanges are set at both ends of the through-tube as connecting joints for connecting the air-water pulse input pipe 10 when cleaning the municipal drainage pipe. In this way, the two sides can be blocked by the end blocking capsule 8 while ensuring the blocking of the inlet and drainage sides of the inspection well. The drainage pipe is cleaned by the air-water pulse cleaning device 9, and no manpower is required for cleaning. After cleaning, the debris is sucked away by the sewage suction pipe of the sewage suction vehicle 14, thereby improving the cleaning efficiency. The annular airbag structure comprises two side bag skins 6, between which N layers of annular bag skins 5 are fixed, and the N layers of annular airbag skins are concentrically arranged to form an N-1 layer of airbag space; By setting N-1 layers of airbag space, it is possible to effectively block municipal drainage pipes of different thicknesses. For example, when the municipal drainage pipe can be blocked after the innermost airbag space is inflated, it is only necessary to inflate the innermost airbag space through the air nozzle. When the innermost airbag space cannot meet the requirements of blocking the municipal drainage pipe, the innermost airbag space and the middle airbag space are inflated through the air nozzle respectively to achieve blocking. Each air nozzle is threadedly connected to an air plug. The structure and working principle of the air plug and the air nozzle are the same as the structure of tire inflation in the prior art, which is not the innovation of the present application and will not be described in detail here. A separate air nozzle 4 for inflating and deflation is fixed at each layer of airbag space.

[0012] The side bladder skin and the annular bladder skin are both rubber bladder skin structures.

[0013] The through-tube is a cylindrical tube with flanges 7 at both ends.

[0014] The through-tube is connected to the center of the annular airbag body by a sealing glue 15, and the two sides of the center of the annular airbag body are flared structures 16. By setting this flared structure, after the through-tube is inserted, the two sides are sealed at the flared position by sealing glue, which can ensure the sealing between the annular airbag body and the through-tube to prevent water leakage.
