Description

Technical Field

[0001] The utility model relates to the technical field of power supply incoming line cabinets, in particular to a protective structure of a power supply incoming line cabinet. Background Art

[0002] The power incoming cabinet is a switch cabinet used to introduce power from the outside. Generally, a 10kV power supply is introduced from the power supply network. The 10kV power supply sends the electric energy to the 10kV bus through the switch cabinet. This switch cabinet is the incoming cabinet. The power incoming cabinet consists of vacuum circuit breakers, disconnectors, three groups of three-coil current transformers, lightning arresters, live displays, voltage transformers, wires and other components.

[0003] For power incoming cabinets installed outdoors, when it rains, rainwater may enter the power incoming cabinet from the heat dissipation port. Since there are many components in the power incoming cabinet, rainwater entering the power incoming cabinet will cause components to short-circuit, thus affecting the normal operation of the equipment. To this end, we propose a power incoming cabinet protection structure. Utility Model Content

[0004] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0005] A protective structure for a power supply incoming line cabinet comprises a cabinet body, wherein heat dissipation openings are provided on both sides of the cabinet body, and rotating shafts are passed through both sides of the cabinet body located below the heat dissipation openings, and rain covers are fixedly connected to opposite sides of the shaft walls of the two rotating shafts, and gears are provided on opposite sides of the shaft walls of the two rotating shafts, and opposite sides of the two gears are respectively fixedly connected to opposite sides of the inner wall of the cabinet body, and limiting grooves are provided on the inner walls of the two gears, and limiting blocks are slidably connected to the inner walls of the two limiting grooves, and one side of the two limiting blocks is respectively fixedly connected to the shaft wall of the corresponding rotating shaft, and a driving device with a variable covering range is provided on the rear side of the inner wall of the cabinet body, and when it rains, the rain cover is rotated so that the rain cover just covers the position of the heat dissipation opening, thereby preventing rainwater from entering the cabinet body through the heat dissipation opening, and further ensuring that rainwater will not damage the electrical components inside the cabinet body when it rains, thereby ensuring the normal operation of the equipment.

[0006] Furthermore, the driving device includes a dual-axis motor fixedly connected to the rear side of the inner wall of the cabinet, and two output ends of the dual-axis motor are fixedly connected to a worm, and opposite sides of the two worms are respectively rotatably connected to the left and right sides of the inner wall of the cabinet, and the rod walls of the two worms are meshingly connected to worm wheels, and the inner walls of the two worm wheels are fixedly connected to screws, and the front and rear ends of the two screws are respectively rotatably connected to the front and rear sides of the inner wall of the cabinet, and the rod walls of the two screws are threadedly connected to tooth plates, and the top surfaces of the two tooth plates are respectively meshingly connected to the bottom surfaces of the corresponding gears, and the opposite sides of the two tooth plates are respectively in contact with the left and right sides of the inner wall of the cabinet.

[0007] Furthermore, a rain sensor is arranged on the top surface of the cabinet.

[0008] Furthermore, a control module is provided on the lower side of the inner wall of the cabinet, and the control module is electrically connected to the dual-axis motor and the rain sensor.

[0009] Furthermore, sealing rings are provided on opposite sides of the two rain covers, and the materials of the two sealing rings are both silicone.

[0010] Furthermore, heat dissipation holes are provided on opposite sides of the two rain covers, and rainproof plates with an L-shaped cross-section are fixedly connected to the heat dissipation holes on the opposite sides of the two rain covers.

[0011] Furthermore, the inner walls of the heat dissipation openings are provided with filter screens.

[0012] The beneficial effects of the utility model are as follows:

[0013] 1. When using this protective structure, when it rains, start the dual-axis motor, and the dual-axis motor rotates the screw through the transmission of the worm gear. Under the transmission action of the gear plate, the screw drives the rain cover to rotate with the rotating shaft, and under the limiting action of the limiting groove and limiting block, the rotation position of the rain cover is limited, so that the rain cover just covers the position of the heat dissipation port, thereby preventing rainwater from entering the cabinet through the heat dissipation port, and then when it rains, rainwater will not damage the electrical components inside the cabinet, thereby ensuring the normal operation of the equipment.

[0014] 2. Monitor whether it is raining through the rain sensor. Once rain is detected, the rain sensor will transmit the signal to the control module, which will be converted into an electrical signal after processing by the control module and transmitted to the dual-axis motor, thereby controlling the operation of the dual-axis motor.

[0015] 3. The sealing ring on the rain cover can prevent rainwater from overflowing from the gap between the rain cover and the cabinet, thereby improving the protective effect of the rain cover. At the same time, the heat dissipation holes and rain shield on the rain cover can ensure the normal heat dissipation of the components inside the cabinet when it rains while preventing the entry of rainwater. The filter can prevent dust from entering the cabinet through the heat dissipation port, thereby enhancing the protective effect of the components inside the cabinet.

Limiting grooves 6 are provided on the inner walls of the two gears 5. Limiting blocks 7 are slidably connected to the inner walls of the two limiting grooves 6. The limiting grooves 6 and the limiting blocks 7 enable the rain cover 4 to rotate only 180 degrees. Reciprocating motion, so that when it rains, the rain cover 4 can completely block the heat dissipation port 2, and when it does not rain, the rain cover 4 will not have a shielding effect on the heat dissipation port 2. One side of the two limit blocks 7 is fixedly connected to the shaft wall of the corresponding rotating shaft 3, and a driving device with a variable covering range is arranged on the rear side of the inner wall of the cabinet 1.

The double-axis motor 8 can synchronously control the two rain cover 4 to rotate, thereby having a certain energy saving performance. The two output ends of the double-axis motor 8 are fixedly connected to a worm 9, and the opposite sides of the two worm 9 are respectively connected to the cabinet The left and right sides of the inner wall of the cabinet 1 are rotatably connected, the rod walls of the two worm gears 9 are meshed with worm wheels 10, the inner walls of the two worm wheels 10 are fixedly connected with screws 11, the front and rear ends of the two screws 11 are respectively rotatably connected with the front and rear sides of the inner wall of the cabinet 1, the rod walls of the two screws 11 are threadedly connected with toothed plates 12, the top surfaces of the two toothed plates 12 are respectively meshed with the bottom surfaces of the corresponding gears 5, and the opposite sides of the two toothed plates 12 are respectively in contact with the left and right sides of the inner wall of the cabinet 1. When using this protective structure, if it does not rain, the rain cover 4 is located below the heat dissipation port 2, and the heat dissipation port 2 is not blocked, so as to prevent the heat dissipation port 2 from being blocked. The cabinet 1 has a good ventilation and heat dissipation effect. When it rains, the dual-axis motor 8 is started. The dual-axis motor 8 drives the screw 11 to rotate through the worm gear 10 and the worm 9.
