Description

Technical Field

[0001] The utility model relates to the field of electrical equipment, in particular to an automatic heat dissipation distribution box. Background Art

[0002] The components inside the distribution box will emit heat during operation, so the inside of the distribution box needs to be cooled. The heat dissipation holes of the distribution box should not be too large to avoid failing to protect the isolation components. At the same time, safety and protection need to be considered, and isolation baffles are required. The existing isolation baffles further compress the heat dissipation space of the circuits and components inside the switchgear. Common electric blinds use electric push rods as a power source, and drive the opening and closing of each blind through a gear transmission mechanism or a connecting rod mechanism. Electric blinds are often installed on existing distribution cabinets to effectively prevent small animals such as mice and snakes, and also have good ventilation effects, allowing indoor heat or other gas exhaust to be better discharged. However, since the electric blinds are installed on the blind bracket by multiple screws, the existing electric blinds are inconvenient to disassemble and assemble when inspecting the internal components of the distribution cabinet, which affects the inspection efficiency. Utility Model Content

[0003] Based on the above problems, the utility model aims to provide a distribution box with automatic heat dissipation.

A sliding groove is arranged on the side, one end of the movable roller is arranged in the sliding groove, and a positioning groove is arranged on the upper end of the sliding groove. The second control line also includes an extension pull rope, and the extension pull rope passes through between the fixed roller and the movable roller and is connected to the second control line. When the extension pull rope is pulled in the direction of the movable roller, the extension pull rope drives the movable roller to move to the positioning groove, and the extension pull rope is clamped between the fixed roller and the movable roller. When the extension pull rope is pulled in the direction of the fixed roller, the movable roller is separated from the extension pull rope and falls back into the sliding groove, and the extension pull rope moves freely. The shutter divides the box body into an inner cavity and an outer cavity. The inner cavity is provided with a temperature sensing mechanism, and the temperature sensing mechanism is electrically connected to the motor. The extension pull rope is arranged in the outer cavity.

[0005] By adopting the above technical scheme, the shutters play a protective barrier role, and a temperature sensing mechanism is provided. When the temperature of the inner cavity is too high, the motor controls the blades to flip and open the gap to exhaust and dissipate heat. Compared with the existing distribution cabinet electric shutter fan which adopts connecting rods or gears to control the flipping of blades, the technical scheme of the utility model controls the flipping of blades by pulling the first control line by the motor, and drives the blades to rise and fall through the second control line by manually pulling the extension pull rope. At the same time, a rope buckle is provided, and the lifting height of the blades can be controlled according to needs. There is no need to disassemble and assemble the blade bracket, and it can be operated manually, and there is no need to pull the extension pull rope all the time. When the extension pull rope is pulled in the direction of the movable roller, the extension pull rope drives the movable roller to move to the positioning groove, and the extension pull rope is clamped between the fixed roller and the movable roller to position the extension pull rope, thereby positioning the lifting height of the blade, which is convenient for inspecting the electronic components in the inner cavity. The blades can be lowered by simply pulling the extension pull rope in the opposite direction. It is simple, labor-saving and easy to operate.

[0008] This embodiment further configures: the air guide channel is configured in a trumpet shape, and the diameter of the upper end of the air guide channel is smaller than the diameter of the lower end.

[0009] By adopting the above technical solution, the impact force of the airflow is strengthened, thereby improving the heat dissipation effect.

[0010] This embodiment is further configured as follows: the mounting frame is provided with a plurality of longitudinally arranged wire grooves and installation cavities, the installation cavities are spaced apart from the guide grooves, the installation cavities are divided into a plurality of single cavities arranged up and down by partitions, the partitions are provided with air holes at positions corresponding to the air guide channels, and the lower ends of the wire grooves are aligned with and connected to the air guide channels.

[0011] By adopting the above technical solution, a wire trough is provided to facilitate installation and wiring, wire management, and improve assembly efficiency. However, there are many wires in the wire trough, which is prone to heat. The cooling fan guides air to the wire trough through the air guide channel. The wire trough is narrow, so the airflow is more concentrated. The airflow rushes upward along the wire trough, and the heat dissipation effect is better. At the same time, although the installation cavity is separated by a partition, it can also be affected by the wind from the air guide channel through the air vents, further improving the heat dissipation effect.

[0012] This embodiment is further configured as follows: blocking members are provided on both sides of the wire trough to prevent the line from detaching, one end of the blocking member is hingedly connected to the mounting frame, a torsion spring is provided between the blocking member and the mounting frame, and the blocking members are correspondingly arranged on both sides of the partition.

The fan-shaped shielding part blocks the possibility of rainwater entering the box through the heat dissipation holes from the side and top. The heat dissipation holes are long and open at the lower end to facilitate ventilation of the heat dissipation holes, thereby improving heat dissipation efficiency.
