[0002] With the development of infrared temperature measurement technology, power grid companies use a large number of infrared temperature measurement equipment in substations to monitor the temperature of primary equipment in operation. By analyzing the temperature, they analyze the operating conditions of the equipment in the substation to ensure the safe operation of the power grid. It is necessary to interfere with the substation with abnormal temperature. For substations with higher temperatures, the power is cut off to the substation to stop working and lower the temperature of the substation. The substation stops working and cannot supply power, which will greatly affect the power supply efficiency of the substation.

[0003] In the prior art, a heating device and a heat dissipation device are installed next to each transformer box. When the transformer box moves, the temperature of the transformer box is disturbed by the heating and heat dissipation devices, so that the temperature of the transformer box can be kept normal, and the power supply of the transformer box will not be affected, so that the power supply efficiency of the substation is high.

[0004] However, the existing method requires that a heating and cooling device be installed next to each transformer box, resulting in a large economic investment. Summary of the invention

[0010] Wherein, the driving component also includes a driving motor, and the number of the driving motors is two. The two driving motors are respectively connected to the two ball screws and are respectively located on one side of the two ball screws away from the two connecting sliders.

[0011] Wherein, the automatic temperature calibration for the substation further includes a positioning component, and the positioning component is connected to the connecting slider.

[0012] Among them, the positioning component includes a slot-type sensor and a sensor sheet. There are multiple slot-type sensors, and the multiple slot-type sensors are symmetrically distributed on both sides of the support platform; there are two sensor sheets, and the two sensor sheets are respectively connected to the two connecting sliders and are respectively located on one side of the connecting slider close to the slot-type sensor.

The heating plate is connected to the two clamping cylinders on one of the sliding plates, and the heating plate is connected to the two clamping cylinders on the other sliding plate. Thus, when the temperature of the transformer box is too high, the sliding plate equipped with the refrigeration plate can be driven to move in front of the transformer box with too high temperature, and the fan is used to blow cold air to the transformer box to cool the transformer box. When the temperature of the transformer box is low, the sliding plate with the heating plate is driven to move in front of the transformer box with low temperature, and the fan is used to blow hot air to the transformer box to heat the transformer box.

[0028] According to this specific implementation, there are multiple transformer boxes 102 , which are evenly distributed on the support platform 101 . The transformer boxes 102 are used to convert and transmit electricity.

[0029] There are two sliding plates 103, and the two sliding plates 103 are connected to the support platform 101 through the driving member. Two fans 104 are arranged on the two sliding plates 103, and the fans 104 are located on the side of the sliding plate 103 away from the support platform 101. Two clamping cylinders 107 are also arranged on the two sliding plates 103. The cooling plate is connected to the two clamping cylinders 107 on the two sliding plates 103 and is located on the two clamping cylinders 107. The heating plate is connected to the other two clamping cylinders 107 and is located on the side of the other two clamping cylinders 107 close to the fan 104. The model of the clamping cylinder 107 is SCX20. Two sliding plates 103 are installed on both sides of the support platform 101. The driving components are connected to the bottom of the two sliding plates 103. Two fans 104 and two clamping cylinders are installed on the two sliding plates 103 respectively. The cooling plate is connected to the two clamping cylinders 107 on one of the sliding plates 103, and the heating plate is connected to the two clamping cylinders 107 on the other sliding plate 103. Thus, when the temperature of the transformer box 102 is too high, the sliding plate 103 equipped with the cooling plate can be driven to move to the transformer box 102 with too high temperature, and the fan 104 blows cold air to the transformer box 102 to cool the transformer box 102.

Only one heating and heat dissipation device is needed to interfere with the temperatures of multiple transformer boxes 102, so as to save economic investment.

[0030] Secondly, the first mounting plate 108 is connected to two of the clamping cylinders 107 and is located on a side of the two clamping cylinders 107 close to the fan 104; the refrigeration pipe 109 is connected to the first mounting plate 108 and is located on a side of the first mounting plate 108 away from the clamping cylinders 107; the second mounting plate 110 is connected to the other two clamping cylinders 107 and is located on a side of the other two clamping cylinders 107 close to the fan 104; the heating pipe 111 is connected to the second mounting plate 110 and is located on a side of the second mounting plate 110 away from the clamping cylinders 107; the first mounting plate 108 has two through holes, and the two through holes of the two clamping cylinders 107 on the left sliding plate 103 are connected to the cooling pipe 111; The output shaft passes through two through holes to clamp the first mounting plate 108. The refrigeration pipe 109 is installed above the first mounting plate 108. The pipeline of the refrigeration pipe 109 is connected to the air compressor. The air is compressed and cooled by the air compressor and then transmitted to the refrigeration pipe 109. The second mounting plate 110 has two through holes. The output ends of the two clamping cylinders 107 on the right sliding plate 103 pass through the two through holes to clamp the second mounting plate 110. The heating pipe 111 is installed on the second mounting plate 110. The heating pipe 111 is a ceramic heating pipe. The heating pipe 111 converts electrical energy into thermal energy, thereby realizing that the device has two temperature regulating devices, making the automatic temperature calibration of the device more sensitive and convenient.

[0031] At the same time, the number of the ball screws 112 is two, and the two ball screws 112 are symmetrically distributed on both sides of the support platform 101; the two ball screws 112 are provided with the connecting sliders 113, and the two connecting sliders 113 are respectively connected to the two sliding plates 103, and the number of the drive motors 114 is two, and the two drive motors 114 are respectively connected to the two ball screws 112 and are located on the side of the two ball screws 112 away from the two connecting sliders 113, and the ball screws are installed on both sides of the support platform 101. 112, the connecting slider 113 is installed on the two ball screws 112, the two connecting sliders 113 are connected to the sliding plate 103, and the two ball screws 112 are driven by the driving motor 114 respectively. At this point, the ball screw 112 is driven to rotate by the driving motor 114, and the rotation of the ball screw 112 is converted into the movement of the connecting slider 113 through the ball screw principle. The sliding plate 103 is driven to move by the connecting slider 113, thereby realizing the temperature adjustment and calibration of the transformer box 102 at different positions.
