Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, in particular to a dust cover for a power distribution cabinet. Background Art

[0002] The power distribution cabinet is divided into power distribution cabinet, lighting distribution cabinet and metering cabinet, which is the final equipment of the power distribution system. The power distribution cabinet is a general term for the motor control center. The power distribution cabinet is used in places where the load is relatively dispersed and there are fewer circuits. The power distribution cabinet distributes the power of a circuit of the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control functions to the load.

[0003] In daily life, the power distribution cabinet will inevitably be covered with dust due to long-term outdoor work. Most of the existing power distribution cabinets do not have dust-proof components during use, resulting in a large amount of dust on the surface of the power distribution cabinet, which is easy to cause damage to components. In addition, in order to increase the heat dissipation effect, some power distribution cabinets have multiple heat dissipation slots on the power distribution cabinet. While improving the heat dissipation effect of the power distribution cabinet, it will also increase the area for dust to enter from the heat dissipation port. This method actually reduces the dust-proof and heat dissipation performance of the power distribution cabinet.

[0004] For this reason, we propose a dust cover for a power distribution cabinet. Utility Model Content

[0005] 1. Technical issues to be solved

[0006] In view of the deficiencies in the prior art, the utility model provides a dust cover for a distribution cabinet, which overcomes the deficiencies in the prior art and solves the problem that in the background technology, most of the existing distribution cabinets do not have dust-proof components during use, resulting in a large amount of dust left on the surface of the distribution cabinet, which easily causes damage to components, and in order to increase the heat dissipation effect, some distribution cabinets have multiple heat dissipation slots on the distribution cabinet. While improving the heat dissipation effect of the distribution cabinet, it also increases the area for dust to enter from the heat dissipation port. This method actually reduces the dust-proof and heat dissipation performance of the distribution cabinet.

[0015] 1. The dust cover of the distribution cabinet can improve the dustproof effect while ensuring the heat dissipation of the distribution cabinet through the coordination of the cabinet body, cover plate, bracket, internal components, base, first heat dissipation slot, bellows, second heat dissipation slot, frame, activated carbon plate, card slot and other structures.

DETAILED DESCRIPTION

[0021] 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.

[0022] Embodiment 1

[0023] See also Figure 1-Figure 2 A dust cover for a power distribution cabinet comprises a cabinet body 1, a cover plate 2 is movably mounted on the front surface of the cabinet body 1, a bracket 3 is fixedly mounted on the inner surface of the cabinet body 1, an internal component 4 is fixedly mounted on the inner surface of the bracket 3, a base 5 is fixedly connected to the lower surface of the cabinet body 1, a first heat dissipation groove 6 is provided on the lower inner wall of the cabinet body 1, two bellows 7 are fixedly mounted on the lower inner wall of the cabinet body 1, second heat dissipation grooves 8 are provided on the left and right surfaces of the cabinet body 1, a frame 9 is fixedly connected to the left and right surfaces of the cabinet body 1, an activated carbon plate 10 is movably mounted on the inner surface of the frame 9, and a card slot 11 is provided on the front surface of the frame 9.

[0024] Specifically, through the coordination among structures such as the cabinet body 1, the cover plate 2, the bracket 3, the internal components 4, the base 5, the first heat dissipation slot 6, the bellows 7, the second heat dissipation slot 8, the frame 9, the activated carbon plate 10, and the card slot 11, the dustproof effect can be improved while ensuring the heat dissipation of the distribution cabinet. By supporting the bottom of the distribution cabinet to a certain height and opening a heat dissipation port at the bottom, the heat dissipation effect can be increased while reducing the entry of dust, thereby achieving a dustproof and heat dissipation effect on the distribution cabinet.

[0025] In this embodiment, the frame 9 is arranged corresponding to the second heat dissipation slot 8 , and the air outlets of the two wind boxes 7 are arranged vertically upward in the cabinet 1 .

[0026] Specifically, the frame 9 completely covers the second heat dissipation slot 8, and the air flow can be blown in the power distribution cabinet through the bellows 7, so as to blow the heat in the power distribution cabinet and dissipate it quickly with the help of the heat dissipation slot to avoid accumulation.

[0027] In this embodiment, the activated carbon plate 10 and the card slot 11 are arranged correspondingly, and the height of the base 5 is set to 20 cm.

[0028] Specifically, the activated carbon plate 10 can ensure that heat can pass through while adsorbing dust circulating in the air. The activated carbon plate 10 can also be easily replaced. The base 5 sets the bottom of the distribution cabinet to a certain height, thereby cooperating with the first heat dissipation slot 6 to increase the heat dissipation space.

[0029] Working principle: When the power distribution cabinet is working, the cabinet body 1 is supported by the base 5 so that the bottom of the cabinet body 1 is 20 cm away from the ground. Then the internal components 4 of the cabinet body 1 are supported by the bracket 3. When the cabinet body 1 is working normally, the cover plate 2 is combined with the cabinet body 1. The internal components 4 of the cabinet body 1 generate heat through long-term operation. The heat can be dissipated to the outside of the cabinet body 1 through the first heat dissipation slot 6 at the bottom and the second heat dissipation slots 8 on both sides. Since the second heat dissipation slots 8 on both sides are covered by the frame 9, the activated carbon plate 10 is installed and inserted into the frame 9 through the card slot 11. The second heat dissipation slots 8 are radiated by the activated carbon plate 10. The cabinet 1 is covered without affecting the heat dissipation outside the cabinet 1. The activated carbon plate 10 can absorb dust in the air to prevent dust from entering the cabinet 1 through the second heat dissipation slot 8. The two bellows 7 in the cabinet 1 can be opened to blow the heat in the cabinet 1 with the wind from the bellows 7 to increase the flow rate of the heat and dissipate it from the second heat dissipation slots 8 on both sides. After long-term use, the activated carbon plate 10 will have reduced air circulation and dust adsorption effects. The activated carbon plate 10 can be quickly replaced in conjunction with the card slot 11 on the frame 9 to ensure the dustproof and heat dissipation effects of the distribution cabinet.

[0030] Embodiment 2

[0031] See also Figure 1 , Figure 3 Based on the first embodiment, the present invention provides a technical solution:

[0032] In this embodiment: a signal concentrator 12 is fixedly mounted on the upper surface of the cabinet 1 , a sensor 13 is fixedly mounted on the upper surface of the cabinet 1 , an alarm 14 is fixedly mounted on the upper surface of the sensor 13 , and a temperature sensing panel 15 is fixedly mounted on the upper inner wall of the cabinet 1 .

[0033] Specifically, through the coordination among structures such as the signal concentrator 12, the sensor 13, the alarm 14, and the temperature sensing panel 15, since heat will float upward in the distribution cabinet, the regional temperature of the inner wall of the distribution cabinet can be monitored in real time. When it is detected that the temperature is too high and has exceeded the safe temperature range set by the temperature sensing panel 15, an alarm is sounded through the alarm 14, thereby reminding the staff to check the abnormally high temperature inside the distribution cabinet.

[0034] In this embodiment, the temperature sensing panel 15 , the signal concentrator 12 , the sensor 13 and the alarm 14 are electrically connected.

[0035] Specifically, the temperature sensing panel 15, the signal concentrator 12, the sensor 13 and the alarm 14 are existing structures, and the control circuit can be implemented through simple programming by technicians in this field. It is common knowledge in this field and is only used without modification. Therefore, the control method and circuit connection will not be described in detail.

[0036] Working principle: When the power distribution cabinet is working normally, the internal components 4 of the cabinet 1 are running for a long time, and the heat generated is dissipated through the heat dissipation slots. The temperature sensing panel 15 is placed in the cabinet 1 through the designated safe temperature range set internally, and the temperature in the cabinet 1 is monitored in real time. When the heat in the cabinet 1 exceeds the safe temperature range through the temperature sensing panel 15, the signal concentrator 12 receives the signal and transmits the signal to the sensor 13. The alarm 14 is turned on through the sensor 13, and the alarm 14 sounds an alarm to remind the staff to check the cause of the abnormal temperature in the power distribution cabinet in time to avoid long-term high temperature and damage to the internal components 4.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
