Ice removing and snow melting protection device used for bridge stay cable

Abstract

The invention discloses an ice removing and snow melting protection device used for a bridge stay cable. The ice removing and snow melting protection device comprises a PE pipe. The inner surface of the PE pipe is fixedly connected with a water absorption expansion device. The inner surface of the water absorption expansion device is fixedly connected with a waterproof film, and a longitudinal opening groove is formed in the waterproof film. A self-temperature-control tracing heat belt is spirally connected between the outer surface of the water absorption expansion device and the inner surface of the PE pipe. By means of the ice removing and snow melting protection device used for the bridge stay cable, due to the arrangement of the water absorption expansion device, the stay cable can beisolated from water flow vapor, the corrosion-resisting, waterproof and rustproof effects of the stay cable can be achieved, and the service life of the stay cable is prolonged; the water absorptionexpansion device can absorb melted snow water so that the size can be enlarged, the water absorption expansion device expands outwards from a pipe opening, and stress ice breaking is achieved; and dueto the arrangement of the opening of the PE pipe, vapor generated by evaporation of the water surface around the stay cable can be absorbed, the device is electrified and used when the temperature ishigh, a dehumidifying effect is achieved in summer, the stay cable is protected, and the service life of the stay cable is prolonged.

Description

technical field [0001] The invention relates to the field of bridge auxiliary facilities, in particular to a stay cable deicing and snow melting protection device. Background technique [0002] The ice and snow covered on the stay cables in winter cannot be melted for a long time. The impurities contained in the ice and snow are easy to corrode the stay cables. The ice and snow itself also increases the load of the stay cables. External factors such as ascent, wind blowing or normal vibration of the cable cause the ice to fall from the cable. When the ice at a higher position falls, due to the high speed, it will pose a major safety hazard to the vehicles running normally on the bridge deck. In severe cases, it will even cause a series of traffic accidents, causing huge personal and property losses. Normal travel is affected. [0003] The heating devices used in existing cable-stayed deicing devices are mainly heating cables, but the heating area is limited. If the winding...

[0002] The ice and snow covered on the stay cables in winter cannot be melted for a long time. The impurities contained in the ice and snow are easy to corrode the stay cables. The ice and snow itself also increases the load of the stay cables. The impact of external factors such as ascent, wind blowing or normal vibration of the cable causes the ice to fall from the cable

When the ice at a higher position falls, due to the high speed, it will pose a major safety hazard to the vehicles running normally on the bridge deck. In severe cases, it will even cause a series of traffic accidents, causing huge personal and property losses. impact on normal travel

[0003] The heating device used in the existing cable-stayed deicing device is mainly heating the heating cable, but the heating area is limited. If the winding is too dense, the material of the heating cable will be wasted, and the effect of loose winding and deicing and snow melting will be uneven, which will easily cause secondary freezing

Moreover, after the ice and snow are melted by the self-controlling heating belt used in the existing bridge, the snow water directly drips or slides down along the stay cables, and lacks a collection device, resulting in waste
