Description

Technical Field

[0001] The utility model relates to the technical field of transmission tools, in particular to a detection and transmission device under an impermeable layer HDPE film. Background Art

[0002] With the increasing awareness of environmental protection, solid waste landfills play a vital role in environmental protection. Among them, the anti-seepage layer HDPE membrane, as an important component of the landfill, its performance directly affects the safety and environmental protection of the landfill. However, due to the complexity of the landfill environment and the particularity of the HDPE membrane material, it may be damaged or leaked during use, thereby causing pollution to the surrounding environment; in order to be able to timely understand the leakage characteristics of the anti-seepage layer HDPE membrane after the production and preparation is completed, it is usually necessary to perform under-membrane detection operations on the anti-seepage layer HDPE membrane. When performing under-membrane detection operations, corresponding transmission devices are usually required. There are many types of transmission devices on the market, and most of the transmission devices use the rotation of the conveying roller to realize the conveying operation of the membrane body.

[0003] However, when most transmission devices are used, the film is easily loosened when using conveyor rollers, and the film cannot be tensioned, which is not conducive to keeping the film in a tensioned state. The loose state of the film is easy to cause mutual obstruction between the film bodies, which will affect the accuracy of the detection and the detection results. In view of this, we proposed a transmission device for detecting the HDPE film under the anti-seepage layer. Utility Model Content
