Description

Technical Field

[0001] The present application relates to the technical field of cable branch boxes, and in particular to an energy-saving and heat-dissipating low-voltage cable branch box. Background Art

[0002] The cable branch box is only used as a cable branch. The main function of the cable branch box is to branch or transfer cables. It mainly plays the role of cable branching and cable transfer. It is a common cable branching and transfer tool.

[0003] For example, a Chinese patent (publication number: CN215009559U) discloses a low-voltage cable branch box that is easy to dissipate heat, including a carrying box, wherein a stable supporting foot is fixedly installed at the corner position of the bottom of the carrying box, a box door is movably installed on the external front of the carrying box, a connecting hinge is movably installed between the external front of the carrying box and the box door, a cooling fan is fixedly installed on the external upper end of the carrying box, a water storage tank is fixedly installed at the lower end position of the external side of the carrying box, a ventilation mesh plate is longitudinally fixedly installed at the side position of the inside of the carrying box, and a water supply pipe is fixedly connected to the side position of the external upper end of the carrying box with a water cooling pipe. The low-voltage cable branch box that is easy to dissipate heat, based on the multi-level heat dissipation holes on the outside, is provided with a heat dissipation fan interconnected with the inside at the upper end of the external part of the whole, so that the internal part of the whole can be effectively dissipated from the outside to the inside during the working process, thereby greatly improving the internal heat dissipation effect of the whole in normal use.

[0004] The above-mentioned low-voltage cable branch box that is easy to dissipate heat still has certain shortcomings. By starting the heat dissipation fan fixed on the upper end of the outer side of the carrying box, combined with the heat dissipation holes opened on the upper end of the carrying box, the heat dissipation performance of the cable branch box as a whole during operation can be significantly improved, and the water supply pump can be started according to the specific usage conditions, so that the cooling water added to the inside of the water storage tank can be sent into the water cooling pipe through the water supply pipe through the water inlet, and then returned to the inside of the water storage tank through the interconnection between the water cooling pipe and the water storage tank, thereby realizing the circulating water cooling and heat dissipation work inside the carrying box. Although the heat dissipation is improved, the simultaneous operation of the heat dissipation fan and the water supply pump not only consumes more energy, but also is inconvenient to adjust according to the temperature inside the branch box, resulting in the heat dissipation fan and the water supply pump working all the time, consuming too much energy. Therefore, the present application proposes an energy-saving and heat-dissipating low-voltage cable branch box to solve the above-mentioned problems. Utility Model Content

[0011] Furthermore, a rotation hole is formed on the upper surface of the fixing plate, and the first rotation rod is rotationally connected to the inside of the rotation hole via a bearing.

[0012] By adopting the above technical solution, the stability of the first rotating rod during rotation is increased.

[0013] Furthermore, the lower surface of the first rotating rod is rotatably connected to the lower surface of the inner cavity of the branch box body through a bearing seat, and the first bevel gear is meshed with the second bevel gear.

[0014] By adopting the above technical solution, the motor drives the first rotating rod and the two first bevel gears to rotate together, and drives the second bevel gear, the second rotating rod and the plurality of third bevel gears to rotate together.

[0015] Furthermore, a plurality of through holes are formed on the upper surface of the fixing plate, and the third rotating rod is rotatably connected to the inside of the through holes via bearings.

[0018] The above technical solution is used to dissipate heat from the low-voltage cables inside the branch box body.

[0019] Furthermore, the cooling pipe is S-shaped, and the upper surface of the third water pipe is fixed to the lower surface of the water tank.

[0020] By adopting the above technical solution, the cooling pipe is in contact with the back of the low-voltage cable to cool the low-voltage cable.

The coolant in the second water pipe 404 enters the cooling pipe 405, and the heat of the cable is dissipated through the cooling pipe 405. After the heat is dissipated, the coolant is cooled under the action of the multiple fan blades 310 and enters the water tank 401 through the third water pipe 406, so as to facilitate the recycling of the coolant.
