Description

Technical Field

[0001] The utility model relates to the technical field of waterproof sleeves, and more specifically, to a new type of waterproof sleeve for electric wells. Background Art

[0002] In recent years, with the rapid economic development, the status of municipal construction has become increasingly prominent. As an important part of municipal construction, electric wells can ensure power safety and guarantee the electricity supply for residents' lives.

[0003] Currently, traditional electric wells are mostly reserved pipeline passage openings. During the pipeline construction process, the working time is relatively long. In case of rainy weather, rainwater flows into the electric well from the reserved passage, which not only causes serious water accumulation in the electric well but also easily generates silt, seriously affecting the construction progress. After the pipeline is sealed, water seepage is also very likely to occur, resulting in water accumulation in the electric well and seriously endangering the safety of power pipelines. Therefore, we propose a new type of waterproof sleeve for electric wells. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a new type of waterproof sleeve for electric wells to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A new type of waterproof sleeve for electric wells, which includes a pipeline inlet. An external threaded pipe is provided at the end of the pipeline inlet, and an internal thread adapted to the external threaded pipe is provided on the inner wall of the pipeline outlet; the pipeline inlet and the pipeline outlet are connected by screwing engagement of the external threaded pipe and the internal thread; a gap is reserved at the connection of the pipeline inlet and the pipeline outlet, and a waterproof rubber ring is sleeved in the gap; a groove is formed on the outer wall of the waterproof rubber ring; an anti-seepage plate is provided on the outer wall of the waterproof rubber ring outside the groove.

[0006] Preferably, a round hole is formed in the middle of the anti-seepage plate, and the round hole is fixedly stuck in the groove.

[0007] Preferably, the outer wall diameter of the pipeline inlet is larger than the outer wall diameter of the external threaded pipe, and the pipeline inlet and the external threaded pipe are integrally formed.

[0008] Preferably, the outer diameter of the pipeline inlet is smaller than the outer diameter of the pipeline outlet.

[0009] Preferably, the groove is in a circular ring structure.

[0010] Advantages: Compared with the prior art, the advantages of the present utility model are as follows: Through the setting of the waterproof sleeve, in a rainy environment, the waterproof sleeve is prefabricated in the power well, greatly reducing the intrusion area of rainwater. The protrusion at the pipeline inlet can effectively prevent rainwater from flowing into the well along the outer wall of the power well; By using the embedded sleeve, which is cast integrally with the power well at one time, it is convenient for pipeline installation, can greatly reduce the seepage of rainwater from the pipe joint, improve the sealing effect of the power well, and effectively prevent node leakage; The setting of the pipeline structure is beneficial to ensuring the safety of various cables, greatly reducing the harm of the humid environment to the cables, and can effectively improve the construction progress; Its cost is low, and the structure is simple and convenient for installation.
