[0029] It should be noted that, when the device is in use, the heat insulation pipe 6 is open at both ends, so that an air duct can be formed in the heat insulation pipe 6, and the heat conduction pipe 71 plays a role in heat conduction, and the heat conduction pipe 71 can transmit the heat in the control cabinet body 1 to the heat insulation pipe 6, so as to realize heat dissipation in the control cabinet body 1.

[0030] It should be further noted that, when the temperature in the control cabinet body 1 is too high, the driving assembly 73 works, and the valve assembly in the heat conduction pipe 71 is opened through the driving assembly 73, at this time, the upper end opening of the heat conduction pipe 71 is in communication with the heat insulation pipe 6, so that the hot air in the control cabinet body 1 can enter the heat insulation pipe 6, thereby improving the heat dissipation efficiency in the control cabinet body 1; when the temperature in the control cabinet body 1 decreases, the valve assembly in the heat conduction pipe 71 is closed through the driving assembly 73.

[0031] Reference Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the driving assembly 73 comprises a movable plate 731, the heat absorption plate 76 is provided with a strip-shaped opening penetrating from top to bottom, the movable plate 731 is slidably connected in the strip-shaped opening, the upper surface of the movable plate 731 is fixedly connected with a baffle 732, and the outer surface of the movable plate 731 is fixedly connected with a magnetic plate 734; the magnetic plate 734 is located below the heat absorption plate 76, and the magnetic plate 734 is elastically connected with the heat absorption plate 76 through the spring 735 which is elongated by heat; the lower surface of the heat absorption plate 76 is mounted with an electromagnet 733, the electromagnet 733 is located directly above the magnetic plate 734, and the magnetic property of the electromagnet 733 is opposite to that of the opposite end of the magnetic plate 734; the outer surface of the heat absorption plate 76 is mounted with a thermistor 737, and the thermistor 737 is connected in series with the electromagnet 733; the outer surface of the movable plate 731 is fixedly connected with a toothed plate 736, and the toothed plate 736 is meshed with the outer gear ring 72.

[0032] It should be noted that when the temperature in the control cabinet body 1 is too high, the resistance of the thermistor 737 increases due to the increase of temperature, and the current passing through the electromagnet 733 decreases due to the series connection of the thermistor 737 and the electromagnet 733, so that the magnetic force of the electromagnet 733 decreases, and the magnetic force between the electromagnet 733 and the magnetic plate 734 decreases; and when the temperature in the control cabinet body 1 is too high, the spring 735 is elongated by heat, and the movable plate 731 moves downward under the action of the gravity of the movable plate 731, the baffle 732, the magnetic plate 734 and the toothed plate 736, thereby driving the toothed plate 736 to move downward synchronously, the outer gear ring 72 and the rotating shaft 74 are driven to rotate forward by the movement of the toothed plate 736, the valve assembly in the heat conducting pipe 71 is opened by the forward rotation of the rotating shaft 74, the upper end opening of the heat conducting pipe 71 is connected with the heat insulation pipe 6, the hot air in the control cabinet body 1 can enter the heat insulation pipe 6, and the external air enters the control cabinet body 1 through the one-way air inlet mechanism 5, so as to improve the heat dissipation efficiency of the control cabinet body 1; and the stroke of the movable plate 731 can be controlled by the baffle 732, when the baffle 732 contacts with the upper surface of the heat absorption plate 76, the valve assembly is completely opened at this time;

[0033] When the temperature in the control cabinet body 1 decreases, the spring 735 will contract, and the resistance of the thermistor 737 will decrease, the current passing through the electromagnet 733 increases, so that the magnetic force of the electromagnet 733 increases; the magnetic force between the electromagnet 733 and the magnetic plate 734 increases, so that the movable plate 731 and the toothed plate 736 move upward, the rotating shaft 74 is reversely rotated by the toothed plate 736, and the valve assembly in the heat conducting pipe 71 is closed by the reverse rotation of the rotating shaft 74; when the electromagnet 733 contacts with the magnetic plate 734, the valve assembly is completely closed at this time;

[0034] In summary, the rate of heat dissipation inside the control cabinet 1 can be automatically adjusted according to the temperature inside the control cabinet 1, thereby reducing the probability of overheating inside the control cabinet 1 and improving the safety and reliability of the device.

[0035] It should also be noted that when the valve assembly is opened, since the heat insulation pipe 6 is connected to the outside and the wall of the heat insulation pipe 6 has a heat insulation function, it can block the temperature inside the control cabinet 1 and ensure that the temperature inside the heat insulation pipe 6 is low. Since the temperature of the air inside the control cabinet 1 is high, the hot air inside the control cabinet 1 will quickly and effectively diffuse into the heat insulation pipe 6 through the heat conduction pipe 71, which is conducive to the discharge of hot air inside the control cabinet 1 and improves the heat dissipation efficiency of the control cabinet 1.

[0036] It should also be noted that the airflow within the heat pipe 71 is unidirectional, thereby preventing impurities in the external air from entering the control cabinet 1 through the heat pipe 71, reducing the chance of damage to the electronic components inside the control cabinet 1, and improving the reliability of the device.

[0037] refer to Figure 2 and Figure 3 As shown, there are multiple heat pipes 71, each of which is equipped with a valve assembly. Each valve assembly is connected to a rotating shaft 74, and the valve assembly is controlled by driving the rotating shaft 74.

[0038] It should be noted that the multiple heat pipes 71 facilitate the guidance of heat inside the control cabinet 1, thereby improving heat dissipation inside the control cabinet 1.

[0039] refer to Figure 4 and Figure 5 As shown, the valve assembly includes a valve seat 78, which is fixedly connected inside the heat pipe 71. A valve core 77 is rotatably connected inside the valve seat 78, and the rotating shaft 74 is fixedly connected to the centerline of the valve core 77.

[0040] It should be noted that when the rotating shaft 74 rotates in the forward direction, it drives the valve core 77 to rotate in the forward direction, so that the valve core 77 is set vertically. At this time, the heat conduction pipe 71 is open, and the upper opening of the heat conduction pipe 71 can be connected to the heat insulation pipe 6. When the rotating shaft 74 rotates in the reverse direction, it drives the valve core 77 to rotate in the reverse direction, so that the valve core 77 is set horizontally. At this time, the heat conduction pipe 71 is closed.

[0041] refer to Figure 4 As shown, the temperature control conduit mechanism 7 also includes a heat-conducting mesh 75, and the outer surface of the heat-conducting pipe 71 is fixedly connected with the heat-conducting mesh 75 for heat conduction.

[0042] It should be noted that the heat conduction net 75 can increase the heat capture capacity in the control cabinet body 1, so that the heat conduction pipe 71 can better transfer heat, thereby facilitating the heat transfer in the control cabinet body 1 to the heat insulation pipe 6, and further facilitating the heat dissipation in the control cabinet body 1.

[0043] Reference Figure 2 As shown, the outer surface of the heat absorption plate 76 is connected with a plurality of elastic heat conduction mechanisms 8 for heat conduction.

[0044] It should be noted that the elastic heat conduction mechanism 8 can increase the heat absorption capacity of the heat absorption plate 76, so that when the heat in the control cabinet body 1 increases, the heat can be timely transferred to the thermistor 737 and the spring 735, thereby ensuring the sensitivity of the device.

[0045] Reference Figure 2 And Figure 8 As shown, the elastic heat conduction mechanism 8 includes a threaded connector 82, the outer surface of the heat absorption plate 76 is provided with a plurality of threaded holes, the threaded holes are threadedly connected with the threaded connector 82, the threaded connector 82 is fixedly connected with a heat-conducting insulating elastic rubber 81 for heat conduction, and the heat-conducting insulating elastic rubber 81 is fixedly connected with a plastic steel wire 83.

[0046] It should be noted that the heat-conducting insulating elastic rubber 81 has the function of heat conduction, and the plasticity of the heat-conducting insulating elastic rubber 81 can be realized through the steel wire 83, so that the heat-conducting insulating elastic rubber 81 can be distributed in the control cabinet body 1 in different shapes within a certain range, thereby facilitating the timely transfer of heat in the control cabinet body 1, ensuring the heat absorption capacity of the heat absorption plate 76, and ensuring that when the heat in the control cabinet body 1 increases, the heat can be timely transferred to the thermistor 737 and the spring 735, thereby ensuring the sensitivity of the device.

[0047] It should also be noted that the heat-conducting insulating elastic rubber 81 wraps the steel wire 83, and the heat-conducting insulating elastic rubber 81 has the characteristic of insulation, so that when the heat-conducting insulating elastic rubber 81 is distributed in the control cabinet body 1, it avoids affecting the electronic components in the control cabinet body 1, such as causing short circuit of the electronic components, thereby improving the safety of the device.

[0048] Reference Figure 1 And Figure 3 As shown, the one-way air inlet mechanism 5 includes a filter box 52, the outer surface of the control cabinet body 1 is fixedly connected with the filter box 52, the air outlet on the upper surface of the filter box 52 is connected with the control cabinet body 1 through a connecting pipe 53, and the connecting pipe 53 is provided with a one-way air inlet valve 51; the air inlet on the bottom of the filter box 52 is connected with an air inlet pipe 54.

[0049] It should be noted that when the gas in the control cabinet body 1 enters the heat insulation pipe 6 through the heat conducting pipe 71, at this time, the external air enters the control cabinet body 1 in turn through the air inlet pipe 54, the filter box 52 and the connecting pipe 53, thereby facilitating the heat dissipation of the control cabinet body 1.

[0050] It should be further noted that the filter box 52 is provided with a filter screen for filtering air, which can reduce the impurities in the external air entering the control cabinet body 1, avoid affecting the electronic components in the control cabinet body 1, and improve the safety of the device.

[0051] Reference Figure 1 and Figure 2 As shown in the figure, the heat insulation pipe 6 is arranged close to the side wall of the control cabinet body 1, and the bottom of the control cabinet body 1 is further fixedly connected with a plurality of open-ended auxiliary heat dissipation pipes 9.

[0052] It should be noted that the auxiliary heat dissipation pipe 9 can increase the air flow passage, and the pipe wall of the auxiliary heat dissipation pipe 9 has the function of heat conduction, thereby facilitating the heat dissipation of the inside of the control cabinet body 1.

[0053] Reference Figure 1 As shown in the figure, the upper surface of the control cabinet body 1 is fixedly connected with two symmetrical lifting rings 4.

[0054] It should be noted that the lifting ring 4 can facilitate the hoisting of the entire control cabinet body 1, facilitate the transfer of the device, and reduce the burden of the operator.

[0055] The working principle of the electrical control cabinet provided by the application is as follows:

[0056] In the use process of the application, when the temperature in the control cabinet body 1 is too high, the resistance of the thermistor 737 increases due to the increase in temperature, and since the thermistor 737 is connected in series with the electromagnet 733, the current passing through the electromagnet 733 decreases, thereby reducing the magnetic force of the electromagnet 733, and the magnetic force between the electromagnet 733 and the magnetic plate 734 decreases; and when the temperature in the control cabinet body 1 is too high, the spring 735 is heated and elongated, and under the action of the gravity of the movable plate 731, the baffle 732, the magnetic plate 734 and the tooth plate 736, the movable plate 731 moves downward, thereby driving the tooth plate 736 to move downward synchronously, the movement of the tooth plate 736 can drive the outer gear ring 72 and the rotating shaft 74 to rotate forward, and the forward rotation of the rotating shaft 74 can open the valve assembly in the heat conducting pipe 71, so that the upper end opening of the heat conducting pipe 71 is in communication with the heat insulation pipe 6, so that the hot air in the control cabinet body 1 can enter the heat insulation pipe 6, and the external air enters the control cabinet body 1 through the one-way air inlet mechanism 5, thereby improving the heat dissipation efficiency of the control cabinet body 1.

[0057] When the temperature in the control cabinet body 1 is reduced, the spring 735 will shrink, and the resistance of the thermistor 737 will decrease, the current through the electromagnet 733 increases, so that the magnetic force of the electromagnet 733 increases; the magnetic force between the electromagnet 733 and the magnetic plate 734 increases, so that the movable plate 731 and the tooth plate 736 move upward, the tooth plate 736 makes the rotating shaft 74 rotate reversely, and the reverse rotation of the rotating shaft 74 can make the valve assembly in the heat conducting pipe 71 close.
