Technical Field

[0001] The present invention relates to the technical field of power distribution cabinets, in particular to a power distribution cabinet with a temperature alarm function. Background Art

[0002] With the initial formation and development of the power system, simple distribution devices began to appear, which were used to distribute the electricity generated by power plants to different electrical equipment and areas. These early distribution cabinets had a relatively simple structure, mainly consisting of some basic switches, fuses and other components, and had relatively simple functions, mainly to achieve on-off control of electricity and basic overload protection.

[0003] Patent publication number CN222547015U relates to a power distribution cabinet with a temperature detection and alarm function, comprising a cabinet body, wherein four right-angled support rods are vertically mounted inside the cabinet body, with the ends of the four right-angled support rods respectively near the inner corner edges of the cabinet body, the openings of the four right-angled support rods corresponding to each other, and a plurality of mounting holes are formed on one side of the right-angled support rods. The power control equipment is installed by the mutual cooperation between the right-angled support rods inside the cabinet body, and the detection assembly is also installed between the right-angled support rods. The temperature sensor body on the square frame can detect the temperature inside the cabinet in real time. When the temperature inside the cabinet rises to a certain level, the alarm body electrically connected to it will sound an alarm, reminding the staff to check the heat dissipation structure or the power control equipment inside the cabinet to prevent the power control equipment inside the cabinet from operating in a high temperature environment for a long time, which will reduce the service life. However, when the device detects a high temperature, the staff must manually cool it down, which is difficult to do automatically. If the staff does not hear the alarm, it is easy to cause damage to the electronic components inside the distribution cabinet. Therefore, a power distribution cabinet with a temperature alarm function is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a power distribution cabinet with a temperature alarm function in view of the deficiencies in the above-mentioned prior art.

It can also blow out the hot air inside the distribution cabinet, so that the inside of the distribution cabinet can be automatically cooled, thereby avoiding the temperature of the distribution cabinet from continuing to rise and causing damage to the internal electronic components. At the same time, the dust generated on the surface of the filter plate can be dropped, so that the ventilation efficiency inside the distribution cabinet can be improved, and the cleaning plate can be enabled to move back and forth, which can further improve the dust cleaning effect of the filter plate, so that the temperature inside the distribution cabinet can be quickly reduced.

When the temperature of the distribution cabinet is too high, the temperature detector will detect the temperature of the distribution cabinet and transmit the electrical signal to the alarm light to alarm, thereby attracting maintenance personnel to detect and take preventive measures to avoid excessive temperature caused by short circuit fire inside the distribution cabinet. It can also blow out the hot air inside the distribution cabinet, so that the interior of the distribution cabinet can be automatically cooled, thereby avoiding the continuous increase in the temperature of the distribution cabinet and causing damage to the internal electronic components. At the same time, the dust generated on the surface of the filter plate can be dropped, so that the ventilation efficiency inside the distribution cabinet can be improved.

At the same time, the push block can hit the cabinet door and then push the cabinet door open, so as to further help the firefighters to extinguish the fire inside the distribution cabinet and prevent the fire from further spreading. The cabinet door can be limited quickly and can be automatically locked, so as to improve the working efficiency of the distribution cabinet during use.

[0010] 3. The distribution cabinet with temperature alarm function can collect scraped dust when cleaning the ventilation window through the coordinated operation of the collection box, the straight plate, the movable door, the second inclined plate, the second sliding rod, the knocking block, the protrusion, and the cleaning plate. After the dust falls into the collection box, the straight plate moves up and no longer squeezes the movable door, so that the movable door rotates through the torsion spring, thereby sealing the dust falling into the collection box, preventing the dust from being blown into the electronic components inside the distribution cabinet by the wind, which may easily cause the problem of electronic short circuit inside the distribution cabinet, and at the same time causing the surface of the filter plate to vibrate, thereby being able to vibrate out the dust remaining in the holes inside the filter plate, thereby improving the ventilation effect of the filter plate and the service life of the filter plate.

The temperature of the cabinet door 2 is too high, making it difficult for the firefighters to open the cabinet door 2, thereby affecting the fire extinguishing progress of the distribution cabinet and the rescue of the fire. At the same time, the sliding push plate 154 moves downward to contact the baffle 1510 and push the baffle 1 510 moves downward, and the baffle 1510 moves downward, driving the moving rod 156 to move downward. The moving rod 156 moves downward, which will cause the moving rod 156 to leave the inside of the push block 159 and release the limit of the elastic rod 158, so that the elastic rod 158 moves forward through the spring and will drive the push block 159 to move together, so that the push block 159 can hit the cabinet door 2 and then push the cabinet door 2 open, which can further help the fire fighters to put out the fire inside the distribution cabinet and prevent the fire from spreading further. When the cabinet door 2 is closed normally, the cabinet door 2 will generate an extrusion force on the inclined plate 153 to make the sliding rod 151 move downward.
