[0017] Compared with the prior art, the utility model has the following beneficial effects: the moisture-proof power cabinet can automatically open the heat dissipation holes when the internal temperature is too high, can actively dissipate heat, and can fully absorb moisture and prevent moisture, thereby increasing the service life of the device. The specific contents are as follows:

[0018] 1. A heat conducting sheet and an air bag are provided. The heat conducting sheet provided by the copper material structure has good heat absorption and heat conduction effects, so that the air bag expands when heated, and then the disc is pushed to rotate, so that the baffle slides, and the openings on the baffle are aligned with the heat dissipation holes to achieve automatic heat dissipation. The structure is simple and practical.

[0019] 2. A disc and a baffle are provided. When the temperature inside the cabinet drops, the airbag contracts and drives the disc to reverse under the action of the torsion spring, so that the baffle slides along the slide groove on the disc, thereby blocking the heat dissipation holes to prevent humid air from outside from entering the cabinet, thus playing a certain moisture-proof role.

[0021] 4. A moisture-proof board is provided. When the heat dissipation holes are opened, the outside air enters into the cabinet through the heat dissipation holes to form air circulation. At this time, the air will first pass through the moisture-proof board, and then through the non-woven fabric layer with the water absorption property, the water vapor in the humid air will be initially absorbed. At the same time, it will be absorbed through the lime layer, which further improves the moisture-proof performance of the device and the dryness inside the cabinet, thereby playing a moisture-proof role.

[0022] 5. A first magnet and a second magnet are provided. When the baffle moves to open the heat dissipation hole, the first magnet and the second magnet are aligned, thereby generating a repulsive force to push the second magnet to slide along the inner wall of the fixed block. Then, the knocking rod is pulled by the pull rope to contract and squeeze the compression spring to contract. At the same time, when the baffle is reset to block the heat dissipation hole, the first magnet and the second magnet are separated. Then, the compression spring pushes the knocking rod to reset and knocks the baffle, thereby shaking off the dust on the filter screen to avoid clogging the filter screen and improve air permeability.

DETAILED DESCRIPTION

[0030] 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.

[0031] Example 1: Please refer to Figure 1-Figure 6 As shown, the utility model provides the following solution: a moisture-proof power cabinet, comprising a cabinet body 1 placed on the ground, and cabinet doors 2 are hinged at the left and right ends of the cabinet body 1;

[0032] The present technical solution sets up the application of a cabinet body 1 and a cabinet door 2. When in use, first perform a safety check on the cabinet body 1, and then place the cabinet body 1 on a stable ground. At this time, install electrical components inside the cabinet body 1. After the installation is completed, close the cabinet door 2 to play a protective role.

[0033] Embodiment 2: The technical content disclosed in this embodiment is an improvement made on the basis of the above embodiment 1. The existing filter screen will cause dust accumulation when used for a long time, thereby affecting the heat dissipation effect. Figure 4-Figure 6 As shown, a heat dissipation component of an electric power cabinet is disclosed, wherein a heat conducting sheet 3 is fixedly connected to the top of a cabinet body 1, and a disc 4 is rotatably installed in a groove opened in the top of the cabinet body 1 through a torsion spring connection, air bags 5 are fixedly connected to the left and right ends of the disc 4, and a slide groove 10 is opened on the disc 4, and a baffle 6 is slidably connected in the slide groove 10, a filter screen 7 is fixedly connected to the top of the baffle 6, and a first magnet 11 is fixedly connected to the side wall of the baffle 6; a fixed block 12 is fixedly connected to the top of the cabinet body 1, a second magnet 14 is slidably connected in the fixed block 12, and the second magnet 14 is connected to the knocking rod 13 through a pull rope. The heat conducting sheet 3 is a copper material structure, and the top of the heat conducting sheet 3 is in contact with the bottom of the air bag 5. The disc 4 is symmetrically arranged with two groups about the cabinet 1, and the slide groove 10 on the disc 4 is symmetrically arranged with two groups, and the slide groove 10 is an arc-shaped structure. The baffle 6 is an "L"-shaped structure, and the baffle 6 is provided with an opening with a diameter equal to the heat dissipation hole 8. The filter screen 7 is arranged on the opening, and the filter screen 7 is an arched structure, and the baffle 6 is slidably connected to the cabinet 1. The first magnet 11 is aligned with the second magnet 14, and the opposite side of the first magnet 11 and the second magnet 14 is the same magnetic pole. The fixed block 12 is symmetrically arranged with two groups about the baffle 6, and a compression spring 15 is connected between the inner wall of the fixed block 12 and the knocking rod 13, and the fixed block 12 and the knocking rod 13 form an elastic telescopic structure through the compression spring 15, and the knocking rod 13 is aligned with the baffle 6.

[0034] In this technical solution, Figure 4As shown, by utilizing the heat conducting sheet 3 and the air bag 5, when the temperature inside the cabinet 1 rises, the heat conducting sheet 3 absorbs heat and transfers the heat to the air bag 5, causing the air bag 5 to expand due to the heat, thereby pushing the disc 4 to rotate, driving the baffle 6 to slide, and automatically opening the heat dissipation holes 8 to form air circulation, which is convenient for dissipating the heat emitted by the power components during operation. At the same time, by setting the filter net 7, dust can be prevented from falling into the cabinet 1, dust accumulation can be avoided, causing damage to electronic components, and the service life of the device can be increased.

[0035] Its use is as Figure 5 and Figure 6 The technical solution shown, first when the temperature inside the cabinet 1 rises, the heat conducting sheet 3 absorbs heat and transmits it to the bottom end of the airbag 5, so that the airbag 5 expands due to the heat, thereby pushing the disc 4 to rotate, and the baffle 6 will slide along the slide groove 10 on the disc 4, automatically aligning the opening with the heat dissipation hole 8, forming air circulation, and dissipating heat. Through the setting of the filter 7, it plays a role in filtering dust in the air, and at the same time, the baffle 6 will drive the first magnet 11 to move synchronously, so that the first magnet 11 is aligned with the second magnet 14, and then the knocking rod 13 is pulled by the pull rope to slide along the inner wall of the fixed block 12 while squeezing the compression spring 15 to contract. When the temperature inside the cabinet 1 drops, the airbag 5 contracts at this time, and under the action of the torsion spring, it drives the disc 4 to reset and rotate, so that the baffle 6 slides and the heat dissipation hole 8 is blocked. At this time, the first magnet 11 is separated from the second magnet 14, so that the compression spring 15 pushes the knocking rod 13 to knock on the baffle 6, and the dust on the filter 7 is shaken off, thereby completing the heat dissipation of the device.

[0036] Embodiment 3: The technical content disclosed in this embodiment is a further improvement based on the above-mentioned embodiments 1 and 2.

The moisture-proof plate 9 is composed of a non-woven fabric layer and a lime layer, and the moisture-proof plate 9 is connected to the cabinet body 1 by screws for easy replacement.

[0037] In this technical solution, Figure 3 As shown, by using the setting of the moisture-proof board 9, the non-woven fabric layer and the lime layer in the moisture-proof board 9 can absorb the humid water vapor in the air at the same time, and the moisture-proof effect is ideal.

[0038] Its use is as Figure 1 and Figure 2The technical solution shown, first when the openings on the baffle 6 are aligned with the heat dissipation holes 8 for heat dissipation, the humid air from the outside will first pass through the moisture-proof plate 9 when it enters the cabinet door 2 through the heat dissipation holes 8. At this time, the non-woven fabric layer in the moisture-proof plate 9 absorbs moisture and plays a preliminary moisture-proof role, so that the preliminary dried gas enters the second layer of the lime layer, which can fully absorb moisture in the air and circulate the dry gas into the cabinet body 1, playing a moisture-proof role. At the same time, when the heat dissipation is completed, the baffle 6 at this time blocks the heat dissipation holes 8, so that the outside air cannot enter the cabinet body 1 through the heat dissipation holes 8, further playing a moisture-proof role.

[0039] The contents not described in detail in this specification belong to the prior art known to the professional and technical personnel in this field. Although the present utility model is described in detail with reference to the above embodiments, it is still possible for the technical solutions recorded in the above embodiments to be modified, or some of the technical features therein to be replaced by equivalents, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
