Assembled cable wall penetrating device

Abstract

The invention discloses an assembled cable wall penetrating device which is used for a cable channel firewall and comprises a loose-leaf pipe body. A plurality of telescopic foot stands are divided into two groups and are linearly arranged and uniformly mounted along the side wall of the loose-leaf pipe body respectively, and the arrangement planes of the two groups of telescopic foot stands are vertical to each other; each group of telescopic foot stands at least comprises two telescopic foot stands, the telescopic foot stands are detachably mounted on the loose-leaf pipe body, and the loose-leaf pipe body indicates that the side wall of the pipe body can be opened and closed. According to the present invention, the cable is isolated from the firewall through the loose-leaf pipe body, theinfluence of free wall penetration on the firewall is reduced to the maximum extent, and in addition, longitudinal and transverse external force generated in cable releasing is dispersed to the innerwall of a cable trench through the telescopic foot stand groups on the loose-leaf pipe body, so that damage of external force of the cable to a fragile fireproof flame-retardant baffle is reduced oreven eliminated, the damage area of the firewall is only the diameter of the loose-leaf pipe body, and large-area damage of the firewall is avoided. According to the assembled cable wall penetrating device, the structure is simple, the assembling and disassembling are convenient, and the occupied space during storage is reduced through the detachable assembling structure.

Description

technical field [0001] The invention relates to the technical field of cable installation safety, in particular to an assembled cable wall penetrator. Background technique [0002] There are a large number of firewalls in the cable trench of the substation. At present, the firewalls are composed of fire-resistant and flame-retardant baffles and fire-proof bags. The fire-resistant and flame-retardant baffles are relatively brittle. Generally, fire-proof sealing is carried out after the cable is laid. However, in the follow-up transformation work, there are a lot of situations where the cables need to pass through the firewall. Due to the heavy weight of the cables themselves, and a large pulling force will be exerted on the cables during the cable release process, especially when the cables need to turn, it is extremely difficult. It is easy to cause the fire-resistant and flame-retardant baffle to be damaged due to excessive external force from the cable, and the fire-proof ...

However, in the follow-up transformation work, there are a lot of situations where the cables need to pass through the firewall. Due to the heavy weight of the cables themselves, and a large pulling force will be exerted on the cables during the cable release process, especially when the cables need to turn, it is extremely difficult. It is easy to cause the fire-resistant and flame-retardant baffle to be damaged due to excessive external force from the cable, and the fire-proof sealing needs to be carried out by a professional company. The force of the cable can also cause damage to the cable
