TECHNICAL FIELD

[0001] The utility model relates to a kind of plugging capsules suitable for drainage pipeline gas-water pulse cleaning. BACKGROUND

[0002] Current municipal drainage pipeline needs to be blocked by plugging capsules when needing to be cleaned, and after blocking, manual cleaning is needed, which consumes a lot of manpower and is difficult to clean. UTILITY MODEL CONTENT

[0003] The utility model aims at making up for the deficiency of prior art, and provides a kind of plugging capsules suitable for drainage pipeline gas-water pulse cleaning.

[0004] The above-mentioned purpose is realized by the following technical solutions:

[0005] A kind of plugging capsules suitable for drainage pipeline gas-water pulse cleaning, the capsule is annular air bag body structure, annular air bag body structure center is fixed with through pipe;

[0006] The annular air bag body structure includes two side skins, N layers of annular skins are fixed between the two side skins, and the N layers of annular air bag skins are concentrically arranged to form N-1 layers of air bag spaces.

[0007] An individual gas charging and discharging nozzle is fixed at each air bag space.

[0008] The plugging capsule suitable for drainage pipeline gas-water pulse cleaning, the side skin and the annular skin are both rubber skin structures.

[0009] The plugging capsule suitable for drainage pipeline gas-water pulse cleaning, the through pipe is a cylindrical pipe, and the two ends have flanges.

[0010] The plugging capsule suitable for drainage pipeline gas-water pulse cleaning, the through pipe is connected to the center of the annular air bag body through a plugging rubber. ADVANTAGEOUS EFFECTS

[0011] 1. The utility model adds a through pipe in the middle part of the annular air bag body, which is a through DN100 steel pipe, so that the plugging air bag tightly wraps the steel pipe, and flanges are arranged at the two ends of the steel pipe as connecting joints for connecting the gas-water pulse input pipeline. In this way, the drainage pipeline can be cleaned using gas-water pulse cleaning technology under the condition of blocking the inlet and outlet of the inspection well, without the need for manual cleaning, which improves the cleaning efficiency.

[0012] 2. The annular air bag body has multiple air bag spaces, which can be used for different diameter municipal drainage pipelines, and the air in the air bag spaces with different layers is inflated to achieve plugging. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0019] Referring to Figures 1-4 , a plugging capsule suitable for air-water pulse cleaning of drainage pipeline, the capsule is annular air bag body 3 structure, the annular air bag body structure center is fixed with through core pipe 2;

[0020] By setting annular air bag body structure, and setting through core pipe, the through core pipe is hollow pipe, when municipal drainage pipeline is cleaned, the flange at both ends of the through core pipe is used as connecting joint, which is used for the connection of air-water pulse input pipeline 10, so that the cleaning of drainage pipeline can be carried out by using air-water pulse cleaning equipment 9 under the condition of ensuring that the inspection well is plugged in and out, and the two sides are plugged by end plugging capsule 8, without manpower for cleaning, after cleaning, the dirt is sucked away through the suction pipeline of suction vehicle 14, and the cleaning efficiency is improved;

[0021] The annular air bag body structure includes two side bag skins 6, N layers of annular bag skins 5 are fixed between the two side bag skins, and the N layers of annular air bag skins are concentrically arranged to form N-1 layers of air bag spaces;

[0022] By setting N-1 layer of air bag space, municipal drainage pipes of different thicknesses can be effectively plugged, for example, when the innermost air bag space is inflated to plug the municipal drainage pipe, only the innermost air bag space needs to be inflated through the air nozzle; when the innermost air bag space cannot meet the plugging of the municipal drainage pipe, the innermost air bag space and the middle air bag space are inflated through the air nozzle respectively, and the plugging can be realized; a gas plug is threadedly connected to each air nozzle, the structure and working principle of the gas plug and the air nozzle are the same as those of the existing technology tire inflation structure, which is not the innovation point of the present application, and will not be described in detail here.

[0023] An individual air charging and discharging air nozzle 4 is fixed at each layer of air bag space.

[0024] The side bag skin and the annular bag skin are both rubber bag skin structures.

[0025] The through pipe is a cylindrical pipe with flanges 7 at both ends.

[0026] The through pipe is connected to the center of the annular air bag body through the sealing glue 15, and the two sides of the annular air bag body center are flared 16 structures. After the through pipe is inserted, the two sides at the flared structure are sealed by the sealing glue, which can ensure the sealing between the annular air bag body and the through pipe and prevent water leakage.
