Description

Technical Field

[0001] This utility model relates to the field of high voltage electrical control cabinet technology, specifically a high voltage electrical control cabinet for machine tools. Background Technology

[0002] High-voltage electrical control cabinets for machine tools are power transmission and transformation equipment used to control machine tools. They are mainly used in power systems for power transmission, distribution, energy conversion, and consumption, playing roles such as switching, control, and protection. Existing high-voltage electrical control cabinets for machine tools have the following main technical defects: They primarily rely on heat sinks and fans to dissipate heat from the machine tool as a whole. However, when the machine tool is running at high speed, the frequency converter used to control the motor speed continuously generates a large amount of heat. Insufficient heat dissipation may lead to a decline in the performance of the frequency converter and affect the stable operation of the equipment. Furthermore, existing heat sinks may allow dust from the workshop to enter the high-voltage electrical control cabinet, leading to a decrease in the insulation performance of the internal electrical components and corrosion, causing inconvenience in daily use.

[0015] 2. This machine tool uses a high-voltage electrical control cabinet. By installing a filter screen on the outside of the heat dissipation slot, dust is reduced from entering the cabinet. Then, the drive motor drives the lead screw to rotate, and the slider works with the brush to clean the filter screen regularly, preventing excessive dust accumulation from affecting the heat dissipation efficiency of the heat dissipation slot.

[0028] Furthermore, the heat dissipation mechanism 6 also includes a temperature sensor 67 fixedly installed inside the housing 1. A mounting bracket 65 is fixedly installed on the side of the heat dissipation plate 61 away from the first heat pipe 62. A cooling fan 66 is symmetrically installed on the side of the mounting bracket 65 away from the heat dissipation plate 61. The cooling fan 66 is used to improve the heat dissipation efficiency of the heat dissipation fins 64. The first heat pipe 62 and the second heat pipe 63 are used to absorb the heat generated when the frequency converter 4 is working. The heat dissipation plate 61 is used to evenly distribute the heat to each set of heat dissipation fins 64.

[0029] Furthermore, the auxiliary mechanism 5 includes an installation box 52 fixedly installed on the side of the housing 1 away from the heat dissipation mechanism 6. A drive motor 51 is fixedly installed on the upper end of the installation box 52. A lead screw 53 is fixedly connected to the output end of the drive motor 51. A guide rod 54 is fixedly installed inside the installation box 52. A slider 55 is threadedly connected to the outside of the lead screw 53. A brush 56 is fixedly installed on one side of the slider 55. A storage groove 57 is slidably connected to the bottom end of the slider 55. A self-locking component 59 is provided inside the slider 55. A filter screen 58 is fixedly installed on the side of the installation box 52 away from the heat dissipation groove 3.

[0030] Furthermore, the filter screen 58 is used to filter dust carried by the airflow, the brush 56 is used to clean the filter screen 58 that has absorbed too much dust, the collection slot 57 is used to collect the dust brushed off by the brush 56, and the self-locking component 59 is used to fix the collection slot 57 and prevent the collection slot 57 from sliding inside the slider 55.

[0031] Furthermore, one side of the heat sink 61 is located inside the housing 1, one end of the first heat pipe 62 and the second heat pipe 63 are respectively fixedly connected to the side of the heat sink 61 located inside the housing 1, the mounting bracket 65 is located outside the heat sink fins 64, and the temperature sensor 67 is located above the frequency converter 4.

[0032] Furthermore, the lead screw 53 is rotatably installed inside the mounting box 52, the lead screw 53 and the guide rod 54 are symmetrically arranged about the mounting box 52, the slider 55 is slidably connected to the guide rod 54, the end of the brush 56 away from the slider 55 is tightly connected to the filter screen 58, and the self-locking component 59 is located at the sliding connection between the slider 55 and the storage groove 57.

[0033] Furthermore, a control component 7 is fixedly installed on the side of the cabinet door 2 away from the box body 1. An observation window 21 is provided on the side of the cabinet door 2 at the bottom of the control component 7. The control component 7 is used to control the operation of the entire equipment and data analysis and processing. The observation window 21 is used by the staff to inspect the inside of the box body 1 from time to time.

[0034] Furthermore, the interior of the housing 1 is also fixedly equipped with evenly distributed electrical components 8.

[0035] The specific usage and function of this embodiment are as follows:

[0036] When in use, the staff first checks whether all components inside the electrical control cabinet are intact. After the check is completed, the required parameters are set through the control system 7, and the internal temperature of the equipment is detected through the temperature sensor 67. Then, the machine tool speed is controlled through the frequency converter 4, and the heat dissipation tank 3 is used to dissipate heat inside the equipment.

[0037] Furthermore, as the machine tool operates for an extended period, when the temperature sensor 67 detects an increase in the temperature of the inverter 4, the first heat pipe 62 absorbs the heat generated on one side of the inverter 4, and the second heat pipe 63 absorbs the heat generated on the other side of the inverter 4. The absorbed heat is then transferred to the heat sink 61 through the other end, and the heat sink 61 distributes the heat evenly to each set of heat sink fins 64. The heat sink fins 64 increase the heat dissipation area by contacting the air. When the machine tool needs to increase its speed to process the workpiece, the temperature sensor 67 detects the temperature of the inverter 4. When the temperature of the inverter 4 is too high, the data is transmitted to the control component 7, and the control component 7 sends a command to the cooling fan 66. The cooling fan 66 then accelerates the heat dissipation efficiency of the heat sink fins 64, thereby rapidly cooling down the inverter 4. The speed of the cooling fan 66 is adjusted in real time based on the temperature of the inverter 4.

[0038] Furthermore, after prolonged operation, excessive dust will accumulate on one side of the filter screen 58, causing a decrease in the heat dissipation effect of the heat dissipation slot 3. By starting the drive motor 51 to rotate, the lead screw 53 will rotate, which in turn will drive the slider 55 to slide. In conjunction with the guide rod 54, the slider 55 will move longitudinally, and the brush 56 will slide on one side of the filter screen 58 to brush away the dust accumulated on the filter screen 58. The dust brushed off will be collected by the collection slot 57 to prevent the dust from flying everywhere. After the dust accumulated on the filter screen 58 is cleaned, the heat dissipation efficiency of the heat dissipation slot 3 can be restored, and subsequent processing work can continue.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
