Description

Technical Field

[0001] The utility model relates to the technical field of resistor cabinets, in particular to a dustproof resistor cabinet. Background Art

[0002] The resistor cabinet is an integrated electronic cabinet that contains a large number of electronic components. Since there are a large number of electronic components inside, and the electronic components are precision components, dust prevention work for the resistor cabinet becomes a necessary condition.

[0003] Existing dust prevention methods all adopt adding a filter to the heat dissipation port to achieve dust isolation inside and outside. However, after the filter is used for a long time, a large amount of dust will adhere to the surface, affecting the internal and external heat dissipation. Therefore, it is necessary to replace and clean the filter, which makes the overall steps more cumbersome, reduces the overall practicality of the device, and manual operation further reduces the degree of automation of the device.

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Example 1

[0018] like Figures 1 to 3 As shown, a dustproof resistor cabinet in the embodiment of the first aspect of the utility model includes a resistor cabinet body 1, a cabinet door 2 is rotatably installed on the front of the resistor cabinet body 1, a mounting ring 3 is fixedly installed on the outer side of the resistor cabinet body 1, a cleaning dustproof component 6 is fixedly installed inside the mounting ring 3, a sliding groove 4 is opened on the outer wall of the resistor cabinet body 1 just below the mounting ring 3, a heat dissipation groove 5 is opened on the outer wall of the resistor cabinet body 1, a cleaning dustproof component 6 is fixedly installed on the inner wall of the resistor cabinet body 1 just above the heat dissipation groove 5, and a mounting frame 7 is fixedly installed inside the cleaning dustproof component 6.

[0019] The cleaning and dust prevention component 6 includes a mounting seat 61, an electric telescopic rod 62 is fixedly installed at the bottom end of the mounting seat 61, a right-angle limit rod 63 is fixedly installed at the bottom end of the electric telescopic rod 62, a sliding plate 64 is fixedly installed at the bottom end of the right-angle limit rod 63, and a heat dissipation auxiliary groove 65 and an air blowing port 66 are respectively opened on the surface of the sliding plate 64.

[0020] The mounting seat 61 is fixedly mounted inside the mounting ring 3 , and the right-angle limiting rod 63 is slidably mounted inside the sliding groove 4 .

[0021] There are three heat dissipation auxiliary grooves 65 , and the sizes of the three heat dissipation auxiliary grooves 65 match the size of the heat dissipation groove 5 .

[0022] A circular groove is formed on the back of the sliding plate 64 , and the circular groove and the air outlet 66 are interconnected. The size of the circular groove matches the size of the end of the fan 8 .

[0023] In the above embodiment, it should be noted that a movable groove is provided inside the heat dissipation groove 5 for the sliding plate 64 to move up and down, so that the two state openings of the sliding plate 64 correspond to the heat dissipation groove 5, and a sensor is provided at the air nozzle of the fan 8. When the circular groove on the back of the sliding plate 64 corresponds, sensing can be performed, so that the fan 8 is automatically turned on, and the automatic blowing process is realized, thereby further simplifying the cleaning steps.

[0024] The technical effect achieved by the above embodiment is: the right-angle limit rod 63 is used to slide inside the sliding groove 4 to ensure that it has a limiting function when moving to prevent displacement. In addition, all the blowing ports 66 are connected to the circular groove on the back of the sliding plate 64 to achieve the cleaning of all positions of the heat dissipation groove 5 at the same time, further improving the overall practicality of the device and reducing the cleaning time.

[0025] Working principle: when too much dust accumulates on the surface of the heat dissipation slot 5, the electric telescopic rod 62 is started to drive the right-angle limit rod 63 to rise. During the process, the right-angle limit rod 63 drives the sliding plate 64 to move, and the heat dissipation sub-slot 65 and the heat dissipation slot 5 are staggered. Instead, the blowing port 66 corresponds to the heat dissipation slot 5, and the inside and outside are separated by the sliding plate 64. When they correspond, the air nozzle of the fan 8 senses the circular groove on the back of the sliding plate 64, thereby starting to infuse air flow into the inside of the sliding plate 64, and finally the air is sprayed out in multiple stages by the blowing port 66 to blow out the dust attached to the inside of the heat dissipation slot 5, thereby achieving the purpose of quickly cleaning the inside.
