Some simplifications or omissions may be made in this section and in the abstract and title of the utility model to avoid obscuring the purpose of this section, the abstract and the title of the utility model, and such simplifications or omissions shall not be used to limit the scope of the present invention.

[0005] In view of the above problems and / or the problems existing in existing municipal pipelines, the present utility model is proposed.

[0006] Therefore, the purpose of the present utility model is to provide a municipal pipeline with a blocking airbag based on municipal control. A bracket is arranged inside the pipeline, and a blocking mechanism is arranged on the bracket. The blocking mechanism uses an airbag as a blocking component.

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Next, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, cross-sectional views of device structures may be partially enlarged and not to scale when describing the embodiments of the present invention. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention.

[0027] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0028] This utility model provides a municipal pipeline with a blocking airbag based on municipal control. A bracket is set inside the pipeline, and a blocking mechanism is set on the bracket. The blocking mechanism uses an airbag as a blocking component. When the airbag is in the contracted state, it does not affect the flow of the pipeline. When the airbag is in the expanded state, it blocks the pipeline and cuts off the water flow, which is convenient for pipeline maintenance. Figures 1-4 , including: a pipeline component 100 and a blocking mechanism 200.

[0029] The pipe component 100 includes a pipe 110, a bracket 120 and a support hole 130. The bracket 120 is provided on the right side of the pipe 110, and the support hole 130 is provided in the center of the bracket 120.

[0030] The left end of the pipe 110 is the inlet end, and the right end is the outlet end. The water flows from left to right. Figure 1 、 Figure 2 and Figure 3 The pipes 110 in the figure are all cross-sectional views to facilitate the display of the internal structure. The bracket 120 is a cross-shaped support member fixed to the inside of the pipe 110 by welding, and the support hole 130 is opened in the center of the bracket 120.

[0031] The blocking mechanism 200 is connected to the support hole 130 and includes a support rod 210 and an airbag 220. The support rod 210 is connected to the support hole 130, and the airbag 220 is provided on the outside of the left end of the support rod 210.

[0032] When the airbag 220 contracts, there is a gap between the airbag 220 and the pipe 110, and water flows through the gap. When the airbag 220 expands, the inner wall of the pipe 110 is sealed, and the airbag 220 is connected to the external inflator.

[0033] Since the inner wall of the pipe 110 is smooth, a gap exists between the airbag 220 and the pipe 110 after the airbag 220 is expanded, which affects the sealing effect. Therefore, a first retaining ring 140 is provided in the center of the pipe 110. The edges of the first retaining ring 140 are all set to a rounded arc shape. After the airbag 220 is expanded, a gap is formed between the airbag 220 and the pipe 110. Figure 2 In the structure, the outer wall of the airbag 220 is squeezed and nested on the first retaining ring 140, thereby improving the sealing effect.

[0034] In order to further improve the sealing effect, a second retaining ring 150 is provided on the left side of the pipe 110, and a valve plate 230 is provided on the left end of the support rod 210. After the airbag 220 is expanded, the valve plate 230 is driven to move left, so that the valve plate 230 is combined with the second retaining ring 150 to form a closed seal. Figure 1 status, further ensuring the blocking effect.

[0035] To prevent the airbag 220 from rotating under the impact of water flow, a limit block 131 is set inside the support hole 130, and a sliding groove 211 is opened on the support rod 210 to be slidably connected to the limit block 131, so that the support rod 210 slides linearly in the support hole 130 to prevent rotation.

[0036] Since the water flow will impact the airbag 220, causing the airbag 220 to be squeezed on the bracket 120 and damaged, a block 212 is provided on the support rod 210 on the right side of the airbag 220. The block 212 is fixed on the support rod 210, and the airbag 220 is shielded and protected by the block 212. The size of the block 212 can be adjusted according to usage requirements.

[0037] In order to prevent the support rod 210 from sliding to the right, the diameter of the stopper 212 is larger than the diameter of the support hole 130, and the stopper 212 is used for holding.

[0038] In specific use, when the airbag 220 shrinks, water flows from the left end of the pipe 110 to the right through the gap between the airbag 220 and the pipe 110. When blocking is required, the airbag 220 expands and seals the inside of the pipe 110. The outer wall of the airbag 220 is squeezed and nested on the first retaining ring 140 to form a stepped structure to improve the sealing effect. At the same time, after the airbag 220 expands, it drives the valve plate 230 to move left, so that the valve plate 230 is combined with the second retaining ring 150 to form a closed structure. Figure 1 status, further ensuring the blocking effect.

[0039] While the present invention has been described above with reference to specific embodiments, various modifications may be made and equivalent components may be substituted without departing from the scope of the present invention. In particular, as long as no structural conflicts exist, the various features of the embodiments disclosed herein may be combined with one another in any manner, and the omission of an exhaustive description of these combinations in this specification is solely for the sake of space and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions within the scope of the claims.
