Abstract
Description
Technical Field
[0001] The present application relates to the technical field of heat dissipation of power distribution cabinets, and in particular to a heat dissipation mechanism of a power distribution cabinet. Background Art
[0002] A power distribution cabinet is a cabinet that integrates electrical components for electric energy distribution (including air switches, circuit breakers, various types of knife switches, terminal blocks, protection devices, measuring equipment, etc.). Due to its good functions, it is widely used in power distribution control for daily use in residential buildings, schools, hospitals, etc. When the existing power distribution cabinet is in use, a large amount of heat will be generated inside the cabinet, causing the temperature inside the cabinet to rise, which is easy to cause damage to the components inside the cabinet. Therefore, heat dissipation ports need to be opened on both sides of the cabinet to dissipate heat inside the cabinet.
[0003] Regarding the above-mentioned related technologies, the inventor believes that, in actual use, in order to prevent dust in the environment from entering the interior of the cabinet and causing damage to the components, it is usually chosen to add a filter at the heat dissipation port to filter the dust. When the temperature is high in summer, the filter will not only affect the heating effect, but also after long-term use, a large amount of dust will adhere to the surface of the filter, resulting in the inability of the cabinet to dissipate heat, which lacks certain practicality.
[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0012] In summary, this application includes the following beneficial technical effects:
[0013] 1. If the temperature is high in summer, the dust screen will affect the heat dissipation effect of the heat dissipation port. You need to start the motor, which drives one set of rotating rods to rotate. The rotating rod drives the other set of rotating rods to rotate through the sprocket and the chain, so that the two sets of rotating rods rotate in the same direction, and then the filter screen wrapped around the rotating rod is rolled up, so that the heat dissipation port is in a fully open state, which improves the heat dissipation effect;

[0019] The following is combined with Figure 1-3 This application is described in further detail.
[0020] The present application embodiment discloses a heat dissipation mechanism for a power distribution cabinet. Figure 1-3A heat dissipation mechanism for a power distribution cabinet comprises a power distribution cabinet body 1, a plurality of heat dissipation ports 2 are symmetrically provided on both sides of the power distribution cabinet body 1, a storage box 3 is fixedly installed on the top of the power distribution cabinet body 1, a protection box 4 is fixedly installed on the back of the storage box 3, a motor 5 is fixedly installed in the protection box 4, a dustproof net 6 is installed on the output end of the motor 5 through a winding mechanism, a plurality of dust exhaust ports 7 are symmetrically provided on both sides of the storage box 3, two groups of support rods 8 are symmetrically provided in the storage box 3, and cleaning brushes 9 cooperating with the dustproof net 6 are fixedly installed on the support rods 8;
[0021] By adopting the above technical solution, two sets of cleaning brushes 9 are arranged inside the storage box 3. When the dustproof net 6 is rolled up, the dust on the outer surface of the dustproof net 6 can be cleaned by the cleaning brushes 9, so that the dustproof net 6 does not need to be cleaned when it is used next time, saving working time.
[0022] Reference Figure 1-3 , slots 10 communicating with the heat dissipation port 2 are provided on both sides of the power distribution cabinet body 1, a weight block 11 is fixedly installed at the bottom of the slot 10, and the dustproof net 6 is fixedly connected to the top of the weight block 11. The winding mechanism includes two groups of rotating rods 12 rotatably installed in the storage box 3, and one group of rotating rods 12 is fixedly connected to the output end of the motor 5, and sprockets 13 are fixedly installed on the rotating rods 12, and the sprockets 13 are connected by chains 14. The dustproof nets 6 are respectively wound on the rotating rods 12, and the winding directions of the two groups of dustproof nets 6 are opposite;
[0023] By adopting the above technical solution, if the temperature is high in summer, the dustproof net 6 will affect the heat dissipation effect of the heat dissipation port 2. It is necessary to start the motor 5, and the motor 5 drives one group of rotating rods 12 to rotate. The rotating rod 12 drives the other group of rotating rods 12 to rotate through the sprocket 13 and the chain 14, so that the two groups of rotating rods 12 rotate in the same direction, and then the filter net wrapped on the rotating rod 12 is rolled up, so that the heat dissipation port 2 is in a fully open state, and the heat dissipation effect is improved. When the dustproof net 6 needs to be activated, it is only necessary to control the motor 5 to reverse, so that the dustproof net 6 on the rotating rod 12 is in a relaxed state, and the gravity provided by the weight block 11 will drive the dustproof net 6 to descend, and then the distribution cabinet body 1 is dust-proof. By arranging two groups of cleaning brushes 9 inside the storage box 3, when the dustproof net 6 is rolled up, the dust on the outer surface of the dustproof net 6 will be cleaned by the cleaning brush 9, so that the dustproof net 6 does not need to be cleaned when it is used next time, saving working time.
[0024] The implementation principle of a heat dissipation mechanism of a distribution cabinet in an embodiment of the present application is as follows: if the temperature is high in summer, the dustproof net 6 will affect the heat dissipation effect of the heat dissipation port 2, and the motor 5 needs to be started. The motor 5 drives one group of rotating rods 12 to rotate, and the rotating rod 12 drives the other group of rotating rods 12 to rotate through the sprocket 13 and the chain 14, so that the two groups of rotating rods 12 rotate in the same direction, and then the filter net wrapped around the rotating rod 12 is rolled up, so that the heat dissipation port 2 is in a fully open state, thereby improving the heat dissipation effect. When the dustproof net 6 needs to be activated, it is only necessary to control the motor 5 to reverse, so that the dustproof net 6 on the rotating rod 12 is in a relaxed state, and the gravity provided by the weight block 11 will drive the dustproof net 6 to descend, thereby preventing the distribution cabinet body 1 from dust.
