Description

Technical Field

[0001] The utility model relates to the technical field of cable distribution boxes, and more specifically, it relates to a cooling device for a cable distribution box. Background Art

[0002] A cable distribution box is a device used for cable tapping, branching, and connection in a power system. It is usually used in outdoor, indoor, or buried locations and can connect power cables to box-type transformers, load switch cabinets, fuse combined electrical cabinets, ring network power supply units, etc., playing the roles of tapping, branching, relaying, or conversion, facilitating the cable network. The hardware inside existing cable distribution boxes generates a large amount of heat during operation. Since existing cable distribution boxes basically do not have the function of rapid heat dissipation, in hot weather, poor heat dissipation easily causes the hardware facilities inside the cable distribution box to overheat and age, reducing the service life of the hardware.

[0003] When cooling by air cooling, the prior art generally uses electric power to drive the fan to rotate to achieve air supply, with relatively large energy consumption. However, when the external wind speed is high, it is not convenient to utilize the external natural wind for air supply, reducing the practicability of the air-cooling device. At the same time, to prevent dust in the air from entering the cable distribution box, a filter screen is usually used to intercept dust. However, the dust will block the filter screen, reducing the ventilation efficiency, and frequent cleaning will increase the labor consumption. Summary of the Utility Model

A fixing slide bar 32 is provided on the other fixed plate 29.

[0030] In this embodiment, when there is natural wind outside, the connecting device is in a disconnected state, and the driving shaft 7 and the second rotating shaft 8 are in a rotationally connected state. The natural wind drives the rotating fan blade 4 to rotate, and then drives the first rotating shaft 3 and the propeller blade 5 to rotate, so as to convey cold air into the filter box 11. After the cold air is conveyed, it is filtered by the filter screen 33 in the filter box 11 to prevent dust from entering the cable distribution box. Start the fixing motor 31, the fixing motor 31 drives the fixing screw 30 to rotate, and then drives the moving blocks 12 and the moving plate 13 to move along the fixing screw 30 and the fixing slide bar 32. When the fixing plate 29 moves, it drives the moving gear 15 to adjust the height, and cooperates with the moving rack 16 to drive the cleaning roller 14 to rotate, and the filter box 11 is cleaned by the cleaning roller 14 to dredge the mesh holes, reducing the frequency of manual cleaning, and having a certain practicality.

[0031] Please refer to Figures 3-5As an implementation method of the connecting device: the connecting device includes a fixed ring 17 and a movable ring 18, the fixed ring 17 is fixedly set on the second rotating shaft 8, the movable ring 18 is slidably set on the driving shaft 7, the fixed ring 17 is provided with a fixed tooth 19, the movable ring 18 is provided with a clamping tooth 20, the tops of the fixed tooth 19 and the clamping tooth 20 are pointed, a limiting groove 21 is provided on the driving shaft 7, a limiting block 22 is provided inside the movable ring 18, a clamping groove 23 is provided on the movable ring 18, a clamping plate 24 and a clamping spring 25 are provided in the clamping groove 23, the clamping tooth 20 is fixedly set on the clamping plate 24, a driving cylinder 26 is provided on one side of the driving motor 6, a driving ring 27 is provided at the output end of the driving cylinder 26, and a driving groove 28 matching the driving ring 27 is provided on the movable ring 18.

[0032] More specifically, when there is no wind outside, the driving cylinder 26 is manually started, and the driving cylinder 26 drives the driving ring 27 to move upward. The driving ring 27 is connected to the moving ring 18 through the driving groove 28, and drives the moving ring 18 to move upward. When the moving ring 18 moves upward, the limit block 22 of the moving ring 18 moves on the limit groove 21 of the driving shaft 7, and the moving ring 18 drives the engaging teeth 20 to move upward. When the fixed teeth 19 contact the engaging teeth 20, there will be a misalignment between the fixed teeth 19 and the engaging teeth 20. At this time, the moving ring 18 continues to move upward, and the fixed teeth 19 squeeze the engaging teeth 20 and the clamping plate 24. The clamping plate 24 squeezes the clamping spring 25, and the clamping spring 25 A continuously increasing upward elastic force is given to the engaging tooth 20, so that the engaging tooth 20 slightly moves the fixed tooth 19, so that the engaging tooth 20 and the fixed tooth 19 are perfectly engaged, releasing the elastic force of the clamping spring 25. At the same time, even if the engaging tooth 20 does not move the fixed tooth 19, when the driving motor 6 drives the driving shaft 7 to rotate the teeth, the rotation of the movable ring 18 can also make the engaging tooth 20 extend into the fixed tooth 19 under the action of the elastic force of the clamping spring 25, connect the movable ring 18 and the fixed ring 17, and then make the driving shaft 7 drive the second rotating shaft 8 to rotate, and through the cooperation of the first bevel gear 9 and the second bevel gear 10, drive the propeller blade 5 to rotate, so as to deliver cold air to the cable branch box for cooling.

[0033] In summary, when the overall equipment is in use or running: when there is natural wind outside, the connecting device is in a disconnected state, the driving shaft 7 and the second rotating shaft 8 are in a rotationally connected state, and the natural wind drives the rotating fan blades 4 to rotate, and then drives the first rotating shaft 3 and the propeller blades 5 to rotate, so as to deliver cold air to the filter box 11. After the cold air is delivered, it is filtered through the filter screen 33 in the filter box 11 to prevent dust from entering the cable branch box, and the fixed motor 31 is started. The fixed motor 31 drives the fixed screw 30 to rotate, and then drives the moving block 12 and the moving plate 13 to move along the fixed screw 30 and the fixed slide rod 32. When the fixed plate 29 moves, it drives the moving gear 15 to adjust the height, and cooperates with the moving rack 16 to drive the cleaning roller 14 to rotate. The filter box 11 is cleaned by the cleaning roller 14 to dredge the mesh, thereby reducing the frequency of manual cleaning and having certain practicality.

[0034] When there is no wind outside, the driving cylinder 26 is manually started, and the driving cylinder 26 drives the driving ring 27 to move upward. The driving ring 27 is connected with the moving ring 18 through the driving groove 28, and drives the moving ring 18 to move upward. When the moving ring 18 moves upward, the limit block 22 of the moving ring 18 moves on the limit groove 21 of the driving shaft 7, and the moving ring 18 drives the engaging teeth 20 to move upward. When the fixed teeth 19 contact the engaging teeth 20, there will be a misalignment between the fixed teeth 19 and the engaging teeth 20. At this time, the moving ring 18 continues to move upward, and the fixed teeth 19 squeeze the engaging teeth 20 and the clamping plate 24. The clamping plate 24 squeezes the clamping spring 25, and the clamping spring 25 gives The upward elastic force of the engaging tooth 20 continues to increase, so that the engaging tooth 20 slightly moves the fixed tooth 19, so that the engaging tooth 20 and the fixed tooth 19 are perfectly engaged, releasing the elastic force of the clamping spring 25. At the same time, even if the engaging tooth 20 does not move the fixed tooth 19, when the driving motor 6 drives the driving shaft 7 to rotate the teeth, the rotation of the movable ring 18 can also make the engaging tooth 20 extend into the fixed tooth 19 under the action of the elastic force of the clamping spring 25, connect the movable ring 18 and the fixed ring 17, and then make the driving shaft 7 drive the second rotating shaft 8 to rotate, and through the cooperation of the first bevel gear 9 and the second bevel gear 10, drive the propeller blade 5 to rotate, so as to deliver cold air to the cable branch box for cooling.

[0035] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described here one by one. In the above, all fixed connections are preferably welded.
