Description

Technical Field

[0001] The utility model relates to the technical field of cable protection, and more specifically, to a cable protection device for coalbed methane wells. Background Art

[0002] Cables are often used in coalbed methane wells to transmit signals or power to equipment in the wells. At present, protective devices are used in coalbed methane wells to protect cables to prevent them from breaking due to friction between the cables and the external soil. Most existing cable protection devices are equipped with a fixed shell and a rotating shell. The cable is placed in the fixed shell, and the rotating shell is placed outside the cable. The rotating shell and the fixed shell are connected together by bolts to fix and protect the cable. However, when the inner diameter of the fixed shell and the rotating shell is large, if the number of cables is small, the cables in the middle will be suspended and the cables cannot be effectively supported and fixed. When the inner diameter is small but the number of cables is large, it is difficult to wrap and protect all the cables. In addition, the cables in the cable protection device are generally messy, and it is difficult to find a cable when it needs to be repaired. At the same time, the rotating shell and the fixed shell are connected by bolts, which makes the installation and removal of the cables more troublesome, time-consuming and labor-intensive.
