| titleOfInvention | The cladding of the shut-off valve of the underground drainage and gas production robot |
| abstract | The utility model discloses a cladding used for a shut-off valve of an underground drainage and gas production robot which is more suitable for the underground operation environment. The cladding of the underground drainage and gas production robot cut-off valve has N axial slits evenly opened along its circumferential direction to form N pieces of elastic strips (1). A zigzag structure (31) is formed so that two adjacent elastic bars (1) are embedded in each other. A friction boss (2) is provided on the outer circumference of the cladding shell near the middle of the axis, and the serrated structure (31) is located at the friction boss (2). The utility model can improve the drainage performance of the underground drainage gas production robot. |
