Description

Technical Field

[0001] This utility model relates to the field of electrical control device technology, and in particular to a high-efficiency power regulation device. Background Technology

[0002] Electrical control devices typically refer to equipment or systems used to control current, voltage, frequency, or other electrical parameters. They are widely used in various fields, including voltage regulators, current controllers, frequency converters, electronic voltage regulators, PWM (pulse width modulation) modulators, and resistance regulators. The core function of electrical control devices is to optimize power usage and improve equipment performance and efficiency by precisely controlling electrical parameters. However, existing electrical control devices lack necessary heat dissipation devices, resulting in severe heat generation of components, which affects the working life and effectiveness of the device. Furthermore, the inner side of the vent filter lacks a necessary self-cleaning structure; while the outer side is easy to clean, the inner side is difficult, and dust adhering to the inner screen affects the device's air intake efficiency. Therefore, this invention proposes a high-efficiency electrical control device to solve the problems mentioned in the background. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-efficiency power control device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A high-efficiency power control device includes a control box. A baffle is fixed to the rear side inside the control box. A filter screen corresponding to the baffle is provided on the rear side of the control box. A scraper that slides left and right inside the control box is provided between the baffle and the filter screen. Cooling fans are installed on both the left and right sides inside the control box. Air outlets corresponding to the cooling fans are opened on both the left and right sides of the control box. Air inlets communicating with the inside of the control box are opened on the left and right corners of the upper side of the baffle, and corresponding blades are provided on the outer side of the air inlets.

[0006] Preferably, the outer side of the scraper bar is in close contact with the inner side of the filter screen, and a reciprocating screw is threadedly connected to the outer side of the upper end of the scraper bar, the reciprocating screw being rotatably connected to the outside of the control box.

[0007] Preferably, a gear is fixed at both the left and right outer ends of the reciprocating screw, and a rotating shaft is provided on the inner side of both ends of the reciprocating screw and rotatably connected to the control box. Another gear is fixed on the circumference of the rotating shaft, and the two adjacent inner and outer gears mesh with each other. The rotating shaft is located inside the air inlet, and a plug is provided at the outer end of the rotating shaft.

[0008] Preferably, the control box is provided with sliding insert shafts on both the left and right sides, and the inner end of the insert shaft is rotatably connected to a sleeve, and the sleeve has a slot for a corresponding insert block.

[0009] Preferably, the two blades are fixed to the lower side of the two sleeves respectively, and the length of the blades is less than or equal to half of the air inlet.

[0010] Preferably, a chip discharge port is provided at the lower rear side of the control box, and the chip discharge port is located below the filter screen and the baffle. A box door is provided at the front side of the control box.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model of electrical control device effectively accelerates air circulation and maintains stable temperature inside the control box by configuring a cooling fan and an air inlet / outlet system. The fan introduces external air and removes internal heat to prevent the equipment from overheating, ensuring that the components operate within a safe temperature range and improving the working efficiency and stability of the equipment. The device achieves automatic cleaning of the filter screen through the linkage design of the scraper and the reciprocating screw.

[0013] 2. The interaction between external airflow and blades drives the rotating shaft to rotate, which in turn drives the scraper to slide, cleaning the dust on the filter screen and maintaining a high-efficiency air filtration effect. This automated cleaning reduces manual intervention, extends the service life of the filter screen, and prevents dust accumulation from obstructing airflow. The linkage mechanism in the design ensures the efficiency and accuracy of the cleaning process, while also avoiding unnecessary energy consumption.

[0014] 3. The design of the chip discharge port on the rear side and the door on the front side of the control box of this utility model allows the dust accumulated during the cleaning process to be discharged smoothly, avoiding re-inhalation and affecting air circulation. The design ensures the stability of the equipment during long-term operation and reduces the impact of dust accumulation on internal components and heat dissipation efficiency.

[0015] In summary, the heat dissipation and filter cleaning design of this electrical control device, through effective air circulation, an automated cleaning system, and the linkage between airflow and scrapers, not only ensures the normal operating temperature of the components inside the control box, but also guarantees the efficient filtration function of the filter, avoiding dust accumulation and equipment overheating. The design has significant advantages in improving equipment stability, reducing manual intervention, and extending service life. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4 A high-efficiency power control device includes a control box 1. A baffle 13 is fixed to the rear side inside the control box 1. A filter 6 corresponding to the baffle 13 is provided on the rear side of the control box 1. A scraper 9 that slides left and right inside the control box 1 is provided between the baffle 13 and the filter 6. Cooling fans are installed on both the left and right sides inside the control box 1. Air outlets 3 corresponding to the cooling fans are opened on both the left and right sides of the control box 1. Air inlets 12 connecting to the inside of the control box 1 are opened on the left and right corners of the upper side of the baffle 13. When the left and right cooling fans inside the control box 1 are working, they introduce outside air into the control box 1 and exhaust it through the air outlets 3 on both sides, thereby accelerating the air circulation inside the control box 1, reducing the working temperature of the components inside the control box 1, and ensuring the continuous normal operation of the control box 1.

[0023] Furthermore, when the aforementioned cooling fan is working, outside air enters between the filter screen 6 and the baffle 13 through the filter screen 6, and then enters the control box 1 through the air inlet 12 at the upper corner. During the process of filtering external dust, the filter screen 6 will accumulate a lot of dust on its surface. The outer side of the scraper 9 is in close contact with the inner side of the filter screen 6. The scraper 9 cleans the surface of the filter screen 6, thereby maintaining the high-quality filtration effect of the filter screen 6 and maintaining a high degree of airflow inside the control box 1.

[0024] Furthermore, a corresponding blade 11 is provided on the outer side of the air inlet 12, and a reciprocating screw 5 is threadedly connected to the outer side of the upper end of the scraper 9. The reciprocating screw 5 is rotatably connected to the outer side of the control box 1. Gears 8 are fixed to the left and right outer ends of the reciprocating screw 5. A rotating shaft is provided on the inner side of both ends of the reciprocating screw 5 and is rotatably connected to the control box 1. The rotating shaft is located inside the air inlet 12, and a plug 14 is provided on the outer end of the rotating shaft. The control box 1 has sliding plug shafts 4 on both the left and right sides. A plug sleeve 10 is rotatably connected to the inner end of the plug shaft 4. A slot corresponding to the plug block 14 is opened inside the plug sleeve 10. The two blades 11 are fixed to the lower side of the two plug sleeves 10 respectively, and the length of the blade 11 is less than or equal to half of the air inlet 12. When it is necessary to clean the inner side of the filter screen 6, it is pressed into the control box 1. Insert the shaft 4 so that the slot inside the shaft 4 fits onto the outside of the corresponding insert block 14, thereby establishing a linkage between the shaft and the insert sleeve 10. As the shaft 4 moves inward, the blade 11 on the insert sleeve 10 also extends to the corresponding position of the air inlet 12. As the airflow enters the control box 1 through the air inlet 12, it impacts the blade 11, causing the shaft and the insert sleeve 10 between the shaft 4 to rotate. The shaft rotates accordingly. Another gear 8 is fixed on the circumference of the shaft. The two adjacent gears 8 mesh with each other. During the rotation of the shaft, the meshing transmission of the two gears 8 causes the outer reciprocating screw 5 to rotate. The rotating reciprocating screw 5 causes the threaded connection to the scraper 9 to slide left and right inside the filter screen 6, thereby cleaning the inside of the filter screen 6.

[0025] Furthermore, a chip discharge port 7 is provided at the lower rear side of the control box 1. The chip discharge port 7 is located below the filter screen 6 and the baffle 13. A door 2 is provided at the front side of the control box 1. Cleaned dust is discharged through the lower chip discharge port 7. When it is not necessary to clean the inside of the filter screen 6, the insert shaft 4 is pulled outward, thereby causing the blade 11 to move out of the corresponding position of the air inlet 12, thus avoiding the transmission between the insert sleeve 10 and the rotating shaft.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
