Description

Cable cavern stopper
Technical field
The utility model belongs to cable fixture field, specifically, particularly relates to a kind of cable cavern stopper.
Background technology
In many transformer stations, many lines are had all to adopt power cable, must through private cable entrance hole when passing through floor or partition wall, for the ease of installing, general cable cavern is larger than power cable diameter, just there is gap after cable installation, fire prevention calking should be blocked at the hole upper and lower wearing power cable according to regulatory requirements.And fire prevention calking due to below cable cavern without supporter, adding the factors such as variation of ambient temperature, set-up time be long, causing fire prevention calking to come off, great potential safety hazard also existed to the reliable and stable operation of device security.Therefore, in the urgent need to finding a kind of effective method, fundamentally solving fire prevention calking and to come off problem.
Summary of the invention
The purpose of this utility model is to provide a kind of cable cavern stopper, and it can realize the shutoff of different pore size cable, and difficult drop-off, long service life.
The utility model is achieved through the following technical solutions:
Cable cavern stopper described in the utility model, comprise fan-shaped shell, fan-shaped internal layer is provided with in described fan-shaped shell, the junction of fan-shaped internal layer and fan-shaped shell is provided with screwed hole, refractory flexible is provided with pullover at the port of fan-shaped internal layer, the outer of fan-shaped shell is arranged with fastening hoop, and fastening hoop is connected with the draw-in groove of fan-shaped shell.
Compared with prior art, the utility model has following beneficial effect:
1, the utility model can realize the shutoff of different pore size cable cavern, and sealing is good, is conducive to the shutoff waterproof to cable and fire protection flame retarding;
2, the utility model can come off by environmental protect variations in temperature, the set-up time fire prevention calking caused such as long, causes the hidden danger of device security stable operation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the cutaway view of A-A in Fig. 1.
In figure: 1, fastening hoop; 2, fan-shaped shell; 3, fan-shaped internal layer; 4, screwed hole; 5, refractory flexible is pullover; 6, draw-in groove.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
Embodiment: a kind of cable cavern stopper, comprise fan-shaped shell 2, fan-shaped internal layer 3 is provided with in described fan-shaped shell 2, fan-shaped internal layer 3 is provided with screwed hole 4 with the junction of fan-shaped shell 2, refractory flexible pullover 5 is provided with at the port of fan-shaped internal layer 3, the outer of fan-shaped shell 2 is arranged with fastening hoop 1, and fastening hoop 1 is connected with the draw-in groove 6 of fan-shaped shell 2.
In conjunction with said structure, before use, fan-shaped internal layer 3 is the inside being positioned at fan-shaped shell 2 to the utility model, can adopt double layer design or the fan-shaped internal layer of Multi-layer design, realize the shutoff to different pore size cable; Fan-shaped internal layer 3 will ensure that it can, in the inner smooth motion of fan-shaped shell 2, need again to ensure that it there will not be situation about putting upside down end to end, therefore can be provided with in the inside of fan-shaped shell 2 and the exterior surface position of fan-shaped internal layer 3 holddown groove making it to slide.
After fan-shaped internal layer 3 is adjusted, by the effect of screwed hole 4 and fastening bolt, fan-shaped internal layer 3 position is fixed, thus the assembled rear shutoff realizing different pore size cable.Can refractory flexible be provided with at fan-shaped internal layer 3 and the contact position of cable pullover, can ensure that fire prevention can ensure again insulation and close contact.
After three pieces of fan-shaped shells 2 are connected by nested structure with fan-shaped internal layer 3, realize again reinforcing by fastening hoop 1 in the periphery of fan-shaped shell 2.
