Description

Technical Field

[0001] The invention relates to the technical field of power distribution cabinets, in particular to a fireproof high-voltage integrated power distribution cabinet. 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 power distribution system. The distribution cabinet is a general term for the motor control center. A large number of connectors and various electronic components are installed inside the distribution cabinet, as well as a large number of wires. Wires, various electronic components and connectors have resistance. Wires, various electrical components and connectors will generate heat when powered on. In order to dissipate the heat inside the distribution cabinet, heat dissipation holes are usually opened on the distribution cabinet.

[0003] Although the heat dissipation holes can dissipate heat inside the distribution cabinet, if a fire occurs near the distribution cabinet, a large amount of heat generated by the fire will enter the distribution cabinet through the heat dissipation holes, thereby affecting the normal use of the electrical components inside the distribution cabinet. If the fire spreads to the distribution cabinet, the flames will enter the distribution cabinet through the heat dissipation holes and cause damage to the electrical components inside the distribution cabinet.

[0004] Therefore, we proposed a fireproof high-voltage integrated distribution cabinet to solve the above problems. Summary of the invention

[0027] A closing plate 4 is arranged on one side of the opening 3 on the supporting box body 2, and is used for emergency closing of the first ventilation hole 30 in the opening 3. A connecting plate 5 is rotatably arranged on the closing plate 4, and one end of the connecting plate 5 away from the closing plate 4 is rotatably connected in the opening 3. A connecting rod 6 is fixedly arranged on the closing plate 4, and a coil spring 7 is fixedly arranged on the connecting rod 6. One end of the coil spring 7 away from the connecting rod 6 is fixedly connected in the opening 3. A foam block 8 is arranged on one side in the opening 3, and one end of the closing plate 4 is placed on the top of the foam block 8.

[0028] By configuring the closing plate 4, the connecting plate 5, the connecting rod 6, the coil spring 7 and the foam block 8, the first ventilation hole 30 communicating with the interior of the distribution cabinet 1 can be closed according to the abnormally high temperature of the outside world, so as to prevent the outside high temperature or fire from entering the interior of the distribution cabinet 1 through the first ventilation hole 30, thereby affecting the normal use of the electrical components inside the distribution cabinet 1 or causing damage to the electrical components inside the distribution cabinet 1.

[0029] A second ventilation hole 9 is provided at the top of the power distribution cabinet 1, a cover plate 10 is provided above the power distribution cabinet 1, two fixing plates 11 are fixedly provided in sequence in the power distribution cabinet 1, and an electric retractor 12 is fixedly provided on the fixing plates 11. The output end of the electric retractor 12 passes through the power distribution cabinet 1 and is fixedly connected to the cover plate 10, a temperature sensor 13 is fixedly provided on the power distribution cabinet 1, and the temperature sensor 13 is electrically connected to the electric retractor 12.

[0030] The second ventilation hole 9 is provided to ventilate and dissipate heat for the distribution cabinet 1. The cover plate 10 can not only prevent dust from forming on the top of the distribution cabinet 1, but also close the second ventilation hole 9 on the top of the distribution cabinet 1, so as to avoid the problem that the entire distribution cabinet 1 is completely closed when the fire near the distribution cabinet 1 further expands and cannot be controlled in time, thereby preventing the external fire from entering the interior of the distribution cabinet 1 and causing damage to the electrical components inside the distribution cabinet 1.

[0031] A fan 14 is provided between the power distribution cabinet 1 and the support box 2, and both ends of the fan 14 pass through the power distribution cabinet 1 and the support box 2 and extend to the inside of the power distribution cabinet 1 and the support box 2. The fan 14 is provided to accelerate the air flow inside the power distribution cabinet 1 during daily use, thereby achieving a better heat dissipation effect inside the power distribution cabinet 1.

[0032] The power distribution cabinet 1 and the support box 2 are both fixedly provided with upright posts 15, the cross section of the upright posts 15 is T-shaped, the power distribution cabinet 1 and the support box 2 are both rotatably provided with sealed door panels 16 through hinges, and door handles are fixedly provided on the sealed door panels 16. The setting of the sealed door panels 16 plays a role in sealing and closing the power distribution cabinet 1 and the support box 2, and the setting of the upright posts 15 plays a role in limiting the rotation angle of the sealed door panels 16.

[0033] A fixing block 17 is provided on one side of the opening 3, a limiting groove is provided on the fixing block 17, the foam block 8 is arranged in the limiting groove, and a plurality of connecting pins 18 are sequentially provided on one side wall of the fixing block 17.

[0034] Working principle of the utility model: when a fire occurs, the temperature near the distribution cabinet 1 will continue to rise, and as the temperature rises, the foam block 8 will expand, and the expansion of the foam block 8 will push the closing plate 4 to flip through the connecting rod 6. When the connecting plate 5 and the coil spring 7 overlap with each other, the foam block 8 continues to expand and pushes the closing plate 4 to flip. At this time, the closing plate 4 will flip under the action of the coil spring 7 until the closing plate 4 is flipped to the inner bottom end of the opening 3, and the first ventilation hole 30 in the opening 3 is closed. When the temperature near the distribution cabinet 1 rises to a certain height, the temperature sensor 13 will transmit an electrical signal to the electric retractor 12, and the electric retractor 12 will start. The start of the electric retractor 12 drives the cover plate 10 to move toward the top of the distribution cabinet 1 until the cover plate 10 is attached to the top of the distribution cabinet 1.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
