Description

Technical Field

[0001] The utility model relates to the technical field of cable laying equipment, in particular to a wiring device for short-term construction power supply. Background Art

[0002] With the rapid development of information technology, communication networks have become an indispensable part of modern society. Cables, as one of the key infrastructures for building communication networks, are being used in more and more places. Cables, as a combination of conductors used to transmit power, communication signals, or data, are typically made of metal conductors (such as copper or aluminum) and wrapped in insulating materials and sheaths to protect the conductors from damage by the external environment and ensure effective transmission. Currently, when a fault occurs at a certain point on a transmission line, but the line must continue to operate, a temporary line is added between the transmitting and receiving ends of the original transmission line at the fault point. This is called a "bypass" solution.

[0003] The traditional laying method of temporary cable lines is usually to lay them directly and arbitrarily on the ground, which cannot effectively protect the cables and is very easy to be crushed by external forces and cause damage and other problems. In addition, although the existing technology usually pre-lays moisture-proof cloth in the ground laying area in order to improve the safety, isolation and integrity of the temporarily laid cable lines, and sets a simplified version of the speed bump type cable protection trough after the cable is laid on the moisture-proof cloth. However, due to the increase in power consumption, the size of existing cables is also increasing synchronously, and the heat generated during operation will also increase synchronously. Although the conventional protection trough can protect the cable body to a certain extent, it cannot perform multiple cable protection in a separate manner, and it is fully contact wrapped, which can easily lead to the cable body that continuously transmits large currents being unable to dissipate heat efficiently, causing the cable body to be very prone to overheating problems, and its full contact wrapping structure cannot effectively buffer the deformation impact force caused by external forces such as trampling and crushing, and it is very easy for the structure to deform and the conductor cable to simultaneously experience pulling and stretching deformation, which reduces the stability and safety of the cable during operation.

[0028] according to Figure 1-2 In a specific embodiment shown, a rigid base plate 1 is laid in a construction area by being placed directly on the ground or by digging a shallow groove on the ground. On the rigid base plate 1, there is a strip side plate 2 that can cooperate with it to construct a strip groove cavity that can accommodate cables. In the strip groove cavity between the two strip side plates 2, a plurality of lower semi-arc positioning strips 3 that can position the cables are arranged at intervals. A heat dissipation sealing component 4 that can seal the top surface of the strip groove cavity is embedded above the strip side plate 2. An upper semi-arc positioning strip 5 that can cooperate with the lower semi-arc positioning strip 3 to limit the cable insertion position in the strip groove cavity is installed on the bottom surface of the heat dissipation sealing component 4. The outer sides of the two strip side plates 2 that are opposite to each other are also provided with a side tilting support component 6 that is detachably mounted on the rigid base plate 1 and constructs an inclined slope surface. The heat dissipation sealing assembly 4 provided in the present application can utilize the airflow directed outward by deformation compression to transfer heat from the cable surface during the deformation process caused by buffering external impact, thereby effectively reducing the operating temperature of the cable and improving the stability and continuous efficiency of the cable during power transmission. The lower half-arc positioning bar 3 and the upper half-arc positioning bar 5 can effectively suspend the cable in the strip groove cavity, achieving insulation isolation of the cable and effectively reducing the intensity of external impact transmitted to the cable, and providing a smooth gap space so that the airflow drives the heat to be discharged from both ends of the strip groove cavity to effectively transfer the working heat. The arc-shaped raised support structure jointly constructed by the heat dissipation sealing assembly 4 and the side inclined support assembly 6 can effectively buffer the deformation impact force caused by external force trampling and crushing by deformation.

[0030] Preferably, a plurality of first limiting arc grooves 32 are spaced apart on the first strip 31 of the lower semi-arc positioning strip 3. Specifically, the first limiting arc groove 32 is provided on the top edge of the vertically arranged first strip 31. Specifically, the first limiting arc groove 32 is a large-radius arc groove body smaller than the semi-circular arc, so that it can effectively rest against the surface of a bold cable with a large cross-sectional radius. The multiple lower semi-arc positioning strips 3 provided in the present application, which are parallel to each other and installed at intervals, can cooperate with each other to carry the cables passing through the strip groove cavity, and can separate multiple cables and place them in different first limiting arc grooves 32 to avoid the cables from being entangled and deformed.

Preferably, the U-shaped positioning baffle 41 is hooked on top of the two strip side panels 2, so that the rigid base plate 1, the strip side panels 2, and the U-shaped positioning baffle 41 jointly define a strip groove cavity. Further preferably, the U-shaped groove cavity defined by the U-shaped positioning baffle 41 is installed with a first heat dissipation exhaust mechanism 42 that can input heat dissipation airflow into the strip groove cavity during its compression deformation process. Further preferably, the top of the U-shaped positioning baffle 41 is also covered with an elastic top plate 43 that can shield the first heat dissipation exhaust mechanism 42. The U-shaped positioning baffle 41 provided in the present application can support and accommodate the first heat dissipation exhaust mechanism 42, so that the first heat dissipation exhaust mechanism 42 can be located above the strip groove cavity, thereby buffering the impact force from above by deformation, and preventing external impact from acting on the cable in the strip groove cavity, and the first heat dissipation exhaust mechanism 42 can compress the volume of the air bag cavity it constructs during the process of deformation caused by the top force, so that it can output airflow to the strip groove cavity to drive the heat dissipated from the surface of the cable to be directionally discharged, thereby achieving effective heat dissipation of the cable and vibration reduction and buffering of the cable. The elastic top plate 43 provided in the present application can protect the first heat dissipation exhaust mechanism 42, and prevent the force structure of the external impact force from directly acting on the first heat dissipation exhaust mechanism 42 and damaging the first heat dissipation exhaust mechanism 42.

The inflatable bag 421 provided in the present application can undergo restorative expansion under the action of the elastic shaping arc plate 422 and the return support spring 423 after completing the external force compression exhaust shrinkage deformation, so that the volume of its bag cavity increases, and in the process of cavity expansion, air is continuously inhaled through the one-way air intake valve 424 to provide a directional external exhaust flow for the next compression process, thereby realizing a continuous supply of heat dissipation airflow.
