Problems solved by technology
[0002] Frost heaves usually occur in winter when power transmission equipment installed in alpine regions causes damage to the power transmission equipment and cannot transmit power normally. Maintenance requires a large-scale power outage. Once the power outage will affect the production and life of the masses, the maintenance cost is high and the impact on society very big

The invention discloses a frost heaving preventing device for a secondary cable residual cable cabin, and relates to the field of frost heaving prevention for the secondary cable residual cable cabin. The structure is as follows: the upper end of a rigid cable protective tube sleeves the interior of a secondary pipe-embedding protective cover, the rigid cable protective tube and the secondary pipe-embedding protective cover are movable, the secondary pipe-embedding protective cover is arranged at the bottom of the secondary cable residual cable cabin, a wiring inspection hole is formed in the secondary cable residual cable cabin, and a secondary cable threading hole is formed in the top of the secondary cable residual cable cabin; a cable passes through the rigid cable protective tube, the secondary pipe-embedding protective cover and the secondary cable residual cable cabin to be connected with the secondary cable threading hole; and a residual cable of the cable is arranged in the secondary cable residual cable cabin. The frost heaving preventing device has the beneficial effects that due to the fact that the rigid cable protective tube and the secondary pipe-embedding protective cover are movable, the rigid cable protective tube can move up and down on the secondary pipe-embedding protective tube during frost heaving or unfreezing, and the residual cable of the cable is arranged in the secondary cable residual cable cabin, so that the cable cannot be broken during frost heaving or unfreezing, an equipment mechanism box cannot be damaged, and the frequency of power failure is reduced.
Description
technical field [0001] The invention relates to the field of anti-frost heave for secondary cable residual cable storage, in particular to an anti-frost heave device for secondary cable residual cable storage. Background technique [0002] Frost heaves usually occur in winter when power transmission equipment installed in alpine regions causes damage to the power transmission equipment and cannot transmit power normally. Maintenance requires a large-scale power outage. Once the power outage will affect the production and life of the masses, the maintenance cost is high and the impact on society very big. Contents of the invention [0003] Aiming at the above-mentioned technical problems, the present invention provides an anti-frost heave device for secondary cable residual cable storage, which is characterized in that: the upper end of the rigid cable protection tube (1) is covered in the secondary buried pipe protection cover (2), and the rigid cable protection tube (1) ...
