Description

Technical Field

[0001] The invention relates to the technical field of control cabinets, in particular to a control cabinet for direct current lighting. Background Art

[0002] A DC lighting control cabinet is a device specifically used to distribute and control DC power. It is mainly used to convert AC power or other power sources into stable DC voltage and distribute it to various lighting fixtures. Its core lies in DC power conversion technology, which usually includes rectification, filtering, voltage stabilization and other links to ensure that the output DC voltage has small fluctuations and high stability, meeting the strict requirements of modern lighting equipment such as LEDs on power quality.

[0003] Reference patent application number CN201910412221.2 is a dustproof and heat-dissipating electrical control cabinet. After the air pollutant filter is dirty, the prior art can drive the dust cleaning soft brush to move down by turning on the electric telescopic rod. The dust cleaning soft brush can drop the dust on the surface of the air pollutant filter through the dust sliding plate. Therefore, by setting the filter, dust can be effectively prevented from entering the control cabinet, and the dust on the surface of the filter can be effectively removed, thereby increasing the dustproof and heat-dissipating capabilities of the device, solving the problem of frequent failures of the control cabinet caused by dust entering the control cabinet, and not processing the filter. However, the patent has the following deficiencies:

An electric telescopic rod 16 is fixedly connected to the bottom of the fixed frame 3, and the movable plate 15 extends to one side outside the ash discharge channel 14 and is fixedly connected to the output end of the electric telescopic rod 16.

[0047] Through the arrangement of the above structure, the sealing plate 12 can prevent the cleaned dust from adhering to the cooling fan 17 and drifting into the cabinet 1 during cleaning, thereby improving the cleaning effect. The electric telescopic rod 16 drives the movable plate 15 to move out of the dust discharge channel 14, so that part of the cleaned dust can be discharged through the dust discharge channel 14.

[0048] Embodiment 4

[0049] In conjunction with Embodiments 1 to 3, please refer to Figures 1 to 4 As shown, the specific improvements are as follows: a cooling fan 17 is arranged inside the fixed frame 3 through a screw mechanism to accelerate the heat dissipation inside the cabinet 1, and the screw mechanism includes a second motor 18 fixed on the top of the fixed frame 3, and the output end of the second motor 18 is fixedly connected to a screw 19, and the bottom end of the screw 19 is rotatably connected to the bottom of the inner wall of the fixed frame 3, and the surface of the screw 19 is threadedly connected to a threaded sleeve 20, and the surface of the threaded sleeve 20 is slidably connected to the inside of the fixed frame 3 through a support rod 21;

[0050] A cavity 22 is provided on one side of the cabinet body 1, and a cooling plate 23 is provided on the surface of the cabinet body 1 and on one side of the cavity 22 through bolts. The interior of the cooling plate 23 and around the heat dissipation holes 24 are hollow to facilitate the passage of cooling water, and a plurality of heat dissipation holes 24 are provided on the surface of the cooling plate 23. The front side of the cooling plate 23 is respectively connected to a water inlet pipe 25 and a water outlet pipe 26 that penetrate to the outside of the fixed frame 3. The water inlet pipe 25 and the water outlet pipe 26 are both connected to an external water supply system. The water supply command is set through an external control system, and the water supply system is a municipal water supply network.

[0051] Through the arrangement of the above-mentioned structure, the screw mechanism can drive the cooling fan 17 to move up and down, so as to evenly dissipate heat in various places inside the control cabinet, and in hot weather, water is circulated into the cooling plate 23 through the external water supply system, so that during the heat exchange process of the cooling fan 17, the external hot air is cooled by the cooling plate 23 and then enters the cabinet body 1, thereby ensuring the heat dissipation effect and improving the cooling efficiency of the control cabinet.

[0052] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment compatible with the equipment can be used.

[0053] When in use, the heat dissipation holes 24 dissipate the heat inside the cabinet 1, and the filter 4 prevents external dust from entering the cabinet 1 through the heat dissipation holes 24. During use of the filter 4, by starting the first motor 512, the threaded rod 513 is driven to rotate. Under the sliding guide of the slide plate 515, the movable sleeve 514 drives the brush plate 53 to reciprocate on the threaded rod 513, and at the same time, the other side of the brush plate 53 slides between the vertical plate 516, so as to clean the filter 4. While cleaning, the two sealing plates 12 are driven to dock through the double-rod hydraulic cylinder 13. The sealing plate 12 is located at the rear side of the filter 4. When cleaning, it can prevent the cleaned dust from adhering to the cooling fan 17 and drifting to the inside of the cabinet 1. By starting the electric telescopic rod 16, the movable plate 15 is driven to move out of the ash discharge channel 14, so that part of the cleaned dust is discharged through the ash discharge channel 14.

[0054] When the brush plate 53 is moved into the frame 7 through the threaded rod 513, the cleaning comb teeth 9 pass through the bristles, and the small electric push rod 10 is started to drive the cleaning comb teeth 9 to move through the base 8. The cleaning comb teeth 9 clean the filamentous dust and other impurities attached to the bristles, so as to keep the brush plate 53 clean during use without affecting the use effect of the brush plate 53. After long-term use, the brush plate 53 is moved to the bottom, and the two arc plates 65 are driven by the handle to move in the opposite direction. The arc plates 65 squeeze the elastic The spring 64 drives the block 66 to move out of the fixing rod 61, and then the fixing rod 61 is moved out of the mounting plate 52, so that the brush plate 53 and the mounting plate 52 can be separated. On the contrary, after the fixing rod 61 passes through the annular plate 62, under the elastic force of the spring 64, the block 66 enters the slot 67, and the fixing seat 63 limits the fixing rod 61. The brush plate 53 and the mounting plate 52 can be installed, which is convenient for replacing the aged brush plate 53 separately, thereby extending the service life of the cleaning mechanism;

[0055] By starting the second motor 18, the screw rod 19 is driven to rotate. Under the sliding guidance of the support rod 21, the threaded sleeve 20 drives the cooling fan 17 to reciprocate on the screw rod 19, thereby accelerating the air circulation inside the cabinet 1. The heat dissipation holes 24 are used to evenly exchange heat inside the cabinet 1, thereby achieving a better heat dissipation effect. At the same time, in hot weather, the external water supply system is connected to the water inlet pipe 25 and the water outlet pipe 26 to circulate water into the cooling plate 23, so that during the heat exchange process of the cooling fan 17, the external hot air is cooled by the cooling plate 23 before entering the cabinet 1, thereby ensuring the heat dissipation effect, cooling the external air, preventing hot air from entering the cabinet 1, and improving the cooling efficiency of the control cabinet.

[0056] 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.
