Description

Technical Field

[0001] This utility model relates to the field of electrical engineering technology, specifically to a dust removal and cooling device for an electrical engineering power cabinet. Background Technology

[0002] Electrical equipment is commonly used in modern production and daily life. It generates a significant amount of heat during operation, requiring cooling to ensure its proper functioning. In practice, electrical equipment is typically housed in cabinets for physical isolation from the outside environment, with ventilation windows installed in the cabinets to lower its temperature. However, as the power of electrical equipment increases, the amount of heat generated per unit time also rises, making ventilation windows insufficient for adequate cooling. Existing dust removal and cooling devices for electrical cabinets have ventilation holes on both sides of the cabinet, creating pathways for dust to enter the interior. Dust tends to accumulate on these extended sections, easily entering the cabinet through these channels and compromising the safety of the electrical facilities. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, one objective of the present invention is to provide a dust removal and cooling device for electrical engineering power cabinets, which has good dust prevention and heat dissipation effects and is easy to maintain.

[0004] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a dust removal and cooling device for an electrical engineering power cabinet, comprising:

[0005] The power cabinet body has an opening on one side wall and a cabinet door is hinged thereto.

[0006] The ventilation mechanism includes two sets of ventilation units symmetrically arranged on the side wall of the power cabinet body. Each set of ventilation units includes a ventilation plate with several through slots. The ventilation plate is detachably mounted on the power cabinet body and has a cleaning part and a first dustproof part.

[0007] The heat dissipation mechanism includes at least one set of heat dissipation units disposed on the side wall of the power cabinet body. Each set of heat dissipation units includes a mounting cover installed on the side wall of the power cabinet body and communicating with the interior of the power cabinet body. The mounting cover has several through holes and a fan is also provided in the mounting cover. The mounting cover has a second dustproof part covering the through holes.

[0008] Preferably, the sidewall of the ventilation plate is provided with an eaves plate that extends obliquely downward along the upper edge of each of the through slots.

[0009] Preferably, the mounting cover includes a cover body and a cover plate detachably mounted on the cover body, and a plurality of the through holes are formed in the cover plate.

[0010] Preferably, the cleaning unit includes mounting plates symmetrically arranged on the side wall of the power cabinet body, a plurality of cleaning rods rotatably arranged between two mounting plates, the side wall of each cleaning rod is provided with bristles, each cleaning rod is provided with a first gear, and a second gear rotatably arranged on the mounting plate meshes between two adjacent first gears, one of the mounting plates is provided with a motor and the drive shaft of the motor is connected to one of the cleaning rods, the cleaning rod is arranged between two eaves boards and the bristles can cooperate with the top surface of the lower eaves board.

[0011] Preferably, the first dustproof part and the second dustproof part respectively include dustproof cotton attached to the power cabinet body and the inner wall of the cover plate.

[0012] Preferably, a temperature sensor is provided on the inner wall of the power cabinet body and is electrically connected to the fan.

[0013] With the above structure, this utility model has the following advantages:

[0014] This application utilizes a ventilation and heat dissipation mechanism, employing slots on the ventilation plate to facilitate air exchange between the inside and outside of the power cabinet, thus helping to reduce the internal temperature. Simultaneously, the through-holes and fan on the mounting cover further accelerate the exhaust of hot air from the power cabinet, improving cooling efficiency. A cleaning section on the ventilation plate removes dust deposited on the eaves, preventing dust from being carried into the electrical cabinet body by airflow. The first and second dustproof sections effectively prevent dust from entering the power cabinet, maintaining a clean internal environment. The detachable design of the ventilation plate and cover facilitates the replacement and maintenance of the dustproof cotton, ensuring dustproof and ventilation effects. An electrical connection between a temperature sensor and the fan enables automatic control of fan operation and speed adjustment based on the internal temperature of the power cabinet, guaranteeing both cooling effectiveness and energy savings.

[0025] Combined with appendix Figures 1-5A dust removal and cooling device for an electrical engineering power cabinet includes a power cabinet body 1 and an air exchange mechanism and a heat dissipation mechanism installed on the power cabinet body 1.

[0026] An opening is provided on one side wall of the power cabinet body 1, and a cabinet door 2 is hinged thereto.

[0027] The ventilation mechanism includes two sets of ventilation units symmetrically arranged on the side wall of the power cabinet body 1. Each set of ventilation units includes a ventilation plate 5 with several through slots 10. The ventilation plate 5 is detachably installed on the power cabinet body 1 and has a cleaning part and a first dustproof part.

[0028] An eaves plate 13 extending obliquely downwards is provided on the side wall of the ventilation plate 5 and along the upper edge of each through groove 10. The eaves plate 13 not only effectively blocks the dust falling from above, but also enhances the rainproof function of the ventilation plate 5 and protects the inside of the power cabinet from rainwater intrusion.

[0029] The cleaning unit includes mounting plates 7 symmetrically arranged on the side walls of the power cabinet body 1. Several cleaning rods 8 are rotatably arranged between the two mounting plates 7. The side walls of the cleaning rods 8 are provided with bristles 9. Each cleaning rod 8 is provided with a first gear 11. A second gear 12 rotatably arranged on the mounting plate 7 meshes between two adjacent first gears 11. One of the mounting plates 7 is provided with a motor 6, and the drive shaft of the motor 6 is connected to one of the cleaning rods 8. The cleaning rods 8 are arranged between two eaves 13, and the bristles 9 can cooperate with the top surface of the lower eaves 13. The cleaning unit realizes automated cleaning. The motor 6 drives the cleaning rods 8 and the bristles 9 to rotate between the two eaves 13 to remove accumulated dust, reduce the frequency of manual cleaning, and improve maintenance efficiency.

[0030] The heat dissipation mechanism includes at least one set of heat dissipation units disposed on the side wall of the power cabinet body 1. Each set of heat dissipation units includes a mounting cover that is installed on the side wall of the power cabinet body 1 and communicates with the interior of the power cabinet body 1.

[0031] The mounting cover includes a cover body 3 and a cover plate 15 that can be detachably mounted on the cover body 3. Several through holes are opened on the cover plate 15. The mounting cover has several through holes and a fan 4 is also provided in the mounting cover. The mounting cover has a second dustproof part covering the through holes.

[0032] The first dustproof part and the second dustproof part include dustproof cotton attached to the inner wall of the power cabinet body 1 and the cover plate 15, respectively. The cover body 3 and the cover plate 15 are detachably connected, and the ventilation plate 5 is detachably connected to the power cabinet body 1, so as to facilitate the replacement and cleaning of the dustproof cotton and prevent blockage.

[0033] A temperature sensor 14 is installed on the inner wall of the power cabinet body 1 and is electrically connected to the fan 4. A programmable controller can be installed. The programmable controller is electrically connected to the motor 6, the fan 4 and the temperature sensor 14 respectively. The fan 4 and the motor 6 are controlled by setting a program.

[0034] During normal operation of the power cabinet, the ventilation mechanism facilitates air exchange between the inside and outside of the cabinet through the through-slots 10 on the ventilation plate 5. When external air enters the power cabinet, it first encounters the eaves 13 on the ventilation plate 5. Because the eaves 13 extends downwards at an angle, most dust is blocked by gravity and airflow, preventing it from passing directly through the through-slots 10. Even if a small amount of dust manages to pass through the eaves 13, it will be further filtered by the first dustproof part (dustproof cotton) on the ventilation plate 5, thus ensuring that the air entering the power cabinet is relatively clean. The motor 6 of the cleaning unit is periodically activated by the programmable controller, which drives the cleaning rods 8 connected to it to rotate. Due to the meshing transmission between adjacent cleaning rods 8 via the first gear 11 and the second gear 12, all cleaning rods 8 rotate synchronously. The bristles 9 on the cleaning rods 8 slide on the top surface of the eaves 13 as the cleaning rods 8 rotate, sweeping away the dust accumulated on the eaves 13. When the electrical equipment inside the power cabinet 1 generates heat, causing the temperature inside the power cabinet to rise, the temperature sensor 14 detects the temperature change and transmits the signal to the programmable controller. Upon receiving the signal, the programmable controller starts the fan 4, which accelerates the airflow inside the mounting cover. The hot air inside the power cabinet is discharged through the through holes in the cover plate 15 of the mounting cover, while external cold air enters the power cabinet through the through slots 10 of the ventilation plate 5 under the suction of the fan 4, thus achieving rapid heat dissipation and reducing the temperature inside the power cabinet.

[0035] The present invention and its embodiments have been described above. This description is not restrictive, and the embodiments shown throughout the text are only one of the embodiments of the present invention. The actual structure is not limited to this. In conclusion, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
