Description

TECHNICAL FIELD

[0001] The present application mainly relates to the technical field of cable bridge, in particular to a cable bridge for assisting cable heat dissipation. BACKGROUND

[0002] The cable bridge is a device for protecting cables, which is divided into groove type, tray type, ladder type and net type structures, and is composed of support, supporting arm and installation accessories. The cable bridge can be divided into five categories according to the manufacturing materials, including steel cable bridge, aluminum alloy cable bridge, stainless steel cable bridge, glass steel cable bridge and flame retardant cable bridge. The cable bridge has the advantages of light structure, high strength, low cost, simple construction, flexible wiring, accurate installation, beautiful appearance and the like, and brings convenience for future technical improvement, cable expansion and maintenance, and is widely used in electronic, mechanical, light industry, textile, metallurgy, power and other departments and high-rise large building feeder cable, control cable commonly used for cable laying device.

[0003] When the cable bridge is installed in a tunnel or basement with poor air flow, the temperature inside the cable bridge will rise due to the heat generated by the cables, and it is difficult to discharge. If the temperature inside the cable bridge is too high, there is a risk of high-temperature damage to the cables. At present, a fan is mainly installed in the cable bridge to improve the air flow inside the cable bridge to achieve the purpose of cooling. For example, the existing patent document 202120727942.5 includes a cable bridge main body, a heat dissipation mechanism is arranged outside the cable bridge main body, a cable arrangement mechanism is arranged inside the cable bridge main body, and two groups of supporting plates are fixedly installed at the bottom of the cable bridge main body. The installation hole is formed in the supporting plate. This structure mainly uses the exhaust fan in the heat dissipation mechanism to achieve the purpose of heat dissipation and cooling of the cables. However, this heat dissipation method can only achieve local cooling of the bridge. Since the overall structure of the bridge is very long, it cannot achieve uniform heat dissipation of the cables inside the bridge, and the heat dissipation intensity is not enough. If the bridge is in a closed tunnel, the temperature difference between the inside and outside of the bridge is small. Even if the heat exchange between the inside and outside of the bridge is realized through the fan, the heat of the cables cannot be quickly reduced. SUMMARY

[0004] The technical solution of the present application provides a significantly different solution from the prior art to solve the technical problem that the prior art solution is too single. Specifically, the present application mainly provides a cable bridge for assisting cable heat dissipation to solve the technical problem that the current cable heat dissipation in the bridge mainly adopts the form of a fan, which can only meet the requirement of local heat dissipation and cannot solve the technical problem of high-intensity heat dissipation in tunnels with poor air flow.

[0005] The technical solution adopted by the present application to solve the above technical problem is:

[0012] Preferably, a connecting frame is provided between every two adjacent groove brackets, and the connecting frame and the side walls of the groove bracket are connected by bolts.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) The present invention realizes that the cables in the bridge can be water-cooled in areas with poor air circulation such as tunnels and basements by setting the groove bracket, top cover, connecting frame, elbow bracket, U-shaped pipe, water pump, water tank, water exchange port, bent pipe, guide pipe, water inlet pipe and return pipe, so as to achieve the purpose of rapid heat dissipation. It can be effectively applied to the situation where the temperature difference between the inside and outside of the bridge is small in a closed environment, providing a low temperature environment and reducing the influence of the external temperature on the cable. The kinetic energy generated during the water flow is used to drive the blades to rotate and the cables in the bridge are air-cooled by the mutual cooperation between the air duct trough body, venturi tube, end cover shell, cover, impeller, rotating fan blade, air collecting hood, air guide pipe and shaft seal, so as to achieve the purpose of heat dissipation and drying, ensure that the environment in the bridge is in a low temperature and dry environment for a long time, and reduce the probability of accidents caused by high temperature to the cable. The structure has linkage, and the air cooling process does not require an additional motor, which saves cost, has a stable structure, is easy to assemble, and has certain application prospects.

[0015] (2) The present invention achieves the function of providing positioning for the cable body through the mutual cooperation between the bent pipe bracket and the U-shaped tube, which facilitates the staff to lay the cable body in the bridge, effectively combines the components for water cooling and the components for positioning, saves materials and space, and makes space utilization more rational. The bent pipe bracket contacts the left and right sides and the bottom side of each cable body to form a semi-enclosed structure, which is uniform and can better take away the heat from the cable body, further improving the heat dissipation efficiency. In addition, with the cooperation of the Venturi tube, according to the Venturi effect, the air flow rate in the bridge is further promoted to improve the heat dissipation efficiency.
