Description

Technical Field

[0001] The present invention relates to the technical field of power distribution cabinets, and in particular to a waterproof power distribution cabinet for communication equipment. Background Art

[0002] The distribution cabinet is divided into power distribution cabinet, lighting distribution cabinet and metering cabinet. It is the final equipment of the distribution system. The distribution cabinet is a general term for the motor control center. The distribution cabinet is used in occasions with dispersed loads and fewer circuits, and the motor control center is used in occasions with concentrated loads and more circuits. They distribute the electrical energy of a circuit of the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load.

[0003] When the existing communication equipment distribution cabinet is in use, the power equipment inside it will generate a lot of heat during operation. The heat accumulated in the narrow distribution cabinet will cause the temperature inside the distribution cabinet to rise rapidly. The excessive temperature will damage the internal components. Therefore, ventilation holes are usually opened on the side walls of the distribution cabinet for heat dissipation. However, in rainy weather, rainwater can enter the distribution cabinet through the ventilation holes, which will cause short circuit damage to the internal power equipment.

DETAILED DESCRIPTION

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific implementation disclosed below.

[0028] Reference Figure 1-5 , a waterproof power distribution cabinet for communication equipment, comprising a power distribution cabinet 1, wherein two first vents 2 are symmetrically provided on a side wall of the power distribution cabinet 1;

[0029] A waterproof mechanism comprises a mounting plate 3, a sliding rod 4, a slider 5, a sealing block 6, a bidirectional lead screw 7, a rotating shaft 8, a first bevel gear 9, a second bevel gear 10 and a first motor 11. Two mounting plates 3 are symmetrically fixedly connected to the inner wall of the distribution cabinet 1. The inner wall of the distribution cabinet 1 is fixedly connected with a sliding rod 4. The sliding rod 4 is arranged to penetrate the two mounting plates 3. Two sliders 5 are symmetrically slidably connected to the side wall of the sliding rod 4. The lower ends of the two sliders 5 are fixedly connected with a sealing block 6 that cooperates with the first vent 2. The inner wall of the distribution cabinet 1 is rotatably connected with a bidirectional lead screw 7. The side wall of the bidirectional lead screw 7 is threadedly connected to the two sliders 5. The inner wall of the distribution cabinet 1 is rotatably connected with a rotating shaft 8. The side wall of the rotating shaft 8 is fixedly connected with the first bevel gear 9. The side wall of the bidirectional lead screw 7 is fixedly connected with the second bevel gear 10. The first bevel gear 9 is meshed with the second bevel gear 10. The side wall of the distribution cabinet 1 is fixedly connected with the first motor 11. The output end of the first motor 11 penetrates the side wall of the distribution cabinet 1 and is fixedly connected to the rotating shaft 8.

[0030] The waterproof mechanism also includes a rainproof top cover 12 fixedly connected to the upper end of the power distribution cabinet 1 .

[0031] Furthermore, in rainy weather, the first motor 11 is driven to rotate, which drives the rotating shaft 8 to rotate, drives the first bevel gear 9 to rotate, and then drives the second bevel gear 10 to rotate, drives the bidirectional screw 7 to rotate, and then the two sliders 5 will slide away from each other, drive the two sealing blocks 6 to move, so that the sealing blocks 6 enter the first vent 2, and seal the first vent 2 to prevent rainwater from entering the interior of the distribution cabinet 1 through the first vent 2, thereby making the distribution cabinet 1 as a whole sealed, achieving a better waterproof effect.

[0032] A heat dissipation mechanism is installed on the power distribution cabinet 1, and the heat dissipation mechanism includes a second vent 13, a mounting block 14, a rotating tube 15, fan blades 16 and a driving assembly. A second vent 13 is opened on the side wall of the power distribution cabinet 1, and the second vent 13 is fixedly connected to the mounting block 14 through multiple fixed shafts. The side wall of the mounting block 14 is rotatably connected to the rotating tube 15, and the side wall of the rotating tube 15 is symmetrically fixedly connected to multiple fan blades 16, and a driving assembly is arranged on the rotating tube 15.

[0033] The driving assembly includes a spline shaft 17, an electric push rod 18, a bracket 19 and a second motor 20. The spline shaft 17 is slidably connected to the inner wall of the rotating tube 15, and the electric push rod 18 is fixedly connected to the inner wall of the distribution cabinet 1. The movable end of the electric push rod 18 passes through the side wall of the distribution cabinet 1 and is fixedly connected to the bracket 19. The lower end of the bracket 19 is fixedly connected to the second motor 20. The output end of the second motor 20 is coaxially fixedly connected to the spline shaft 17. The electric push rod 18, the second motor 20 and the external power supply are connected in series through wires.

[0034] Furthermore, in clear weather, the second motor 20 is energized to drive the second motor 20 to rotate. At this time, the electric push rod 18 will also be energized and extended, driving the second motor 20 to move outward, so that the rain cover 21 is not in contact with the side wall of the distribution cabinet 1, and the second vent 13 is blocked. The rotation of the second motor 20 will drive the spline shaft 17 to rotate, and then drive the rotating tube 15 to rotate, and drive the multiple fan blades 16 to rotate, generating a suction force, pumping the external air into the distribution cabinet 1 through the second vent 13, and then the air inside the distribution cabinet 1 will be discharged through the first vent 2, thereby enhancing the ventilation inside the distribution cabinet 1 and achieving rapid heat dissipation.

[0035] A rain cover 21 that cooperates with the second vent 13 is fixedly connected to the side wall of the second motor 20 .

[0036] It is worth mentioning that in rainy weather, the second motor 20 is powered off. At this time, the electric push rod 18 will be powered off and shortened, driving the second motor 20 to move toward the distribution cabinet 1, and then driving the rain cover 21 to fit the side wall of the distribution cabinet 1, covering the second vent 13, preventing rainwater from entering the distribution cabinet 1 through the second vent 13, thereby enhancing the waterproof effect of the distribution cabinet 1.

[0037] The heat dissipation mechanism also includes a heat dissipation pipe 22, a water collecting tank 23, a water inlet pipe 24 and a water outlet pipe 25. Two heat dissipation pipes 22 are symmetrically fixedly connected to the inner wall of the distribution cabinet 1. A water collecting tank 23 is opened at the upper end of the rainproof top cover 12. The heat dissipation pipe 22 is connected to the water collecting tank 23 through the water inlet pipe 24. The other end of the heat dissipation pipe 22 is fixedly connected to the water outlet pipe 25, and the lower end of the water outlet pipe 25 is arranged to pass through the lower end of the distribution cabinet 1.

[0038] Furthermore, rainwater will fall into the water collecting trough 23, and the rainwater in the water collecting trough 23 will enter the heat dissipation pipe 22 through the water inlet pipe 24. The rainwater flows in the heat dissipation pipe 22 and will generate heat exchange with the power equipment inside the distribution cabinet 1, thereby playing a heat dissipation role. Finally, the rainwater will be discharged through the water outlet pipe 25, so that the rainwater can be utilized to avoid waste of resources.

[0039] A first filter 26 is fixedly connected to the inner wall of the first vent 2, and a second filter 27 is fixedly connected to the inner wall of the second vent 13. When air enters and exits the first vent 2 and the second vent 13, the first filter 26 and the second filter 27 will intercept dust in the air to prevent dust from entering the distribution cabinet 1 and causing short circuit damage to the electrical equipment.

[0040] A cabinet door 28 is rotatably connected to the inner wall of the power distribution cabinet 1 , and a handle 29 is fixedly connected to the side wall of the cabinet door 28 .

[0041] In the present invention, under normal sunny weather conditions, the second motor 20 is energized and rotates. At this time, the electric push rod 18 is also energized and extended, driving the second motor 20 to move outward, so that the rain cover 21 does not fit the side wall of the distribution cabinet 1, and the second vent 13 is blocked. The rotation of the second motor 20 will drive the spline shaft 17 to rotate, and then drive the rotating tube 15 to rotate, and drive the multiple fan blades 16 to rotate, generating a suction force, pumping external air into the distribution cabinet 1 through the second vent 13, and then the air inside the distribution cabinet 1 will be discharged through the first vent 2, thereby strengthening the ventilation inside the distribution cabinet 1 and achieving rapid heat dissipation. When the air enters and exits the first vent 2 and the second vent 13, the first filter 26 and the second filter 27 will intercept dust in the air to prevent dust from entering the distribution cabinet 1 and causing short-circuit damage to the electrical equipment.

[0042] In rainy weather, the second motor 20 is powered off. At this time, the electric push rod 18 will be powered off and shortened, driving the second motor 20 to move toward the distribution cabinet 1, and then driving the rain cover 21 to fit the side wall of the distribution cabinet 1, covering the second vent 13, to prevent rainwater from entering the distribution cabinet 1 through the second vent 13, and then driving the first motor 11 to rotate, driving the rotating shaft 8 to rotate, driving the first bevel gear 9 to rotate, and then driving the second bevel gear 10 to rotate, driving the bidirectional lead screw 7 to rotate, and then the two sliders 5 will slide away from each other, driving the two sealing blocks 6 to move, so that the sealing blocks 6 enter the first vent 2, and seal the first vent 2, to prevent rainwater from entering the distribution cabinet 1 through the first vent 2, and then make the distribution cabinet 1 as a whole sealed, to achieve a better waterproof effect.

[0043] However, since the distribution cabinet 1 is sealed as a whole, the heat dissipation effect will be deteriorated. At this time, rainwater will fall into the water collecting trough 23, and the rainwater in the water collecting trough 23 will enter the heat dissipation pipe 22 through the water inlet pipe 24. The rainwater flows in the heat dissipation pipe 22 and will produce heat exchange with the power equipment inside the distribution cabinet 1, thereby playing a heat dissipation role. Finally, the rainwater will be discharged through the water outlet pipe 25, so that the rainwater can be utilized to avoid waste of resources.

[0044] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
