Also, specific terms can be selected by the applicant, and in this case, the detailed meanings thereof will be described in the detailed description of the present application. Therefore, the terms used in the specification should not be understood as simple names, but based on the meanings of the terms and the general description of the present application.

[0026] Referring to Figure 1 , the embodiment provides a maintenance device for power transformation equipment, comprising a moving unit 1 for supporting the whole device and moving the device, the moving unit 1 comprising a lifting truck 11 and a support platform 12 arranged at the end of the lifting truck 11; a maintenance unit 2 arranged on the support platform 12, comprising an infrared lens 21 and a refrigeration fan 22, the infrared lens is used for focusing infrared radiation signals and temperature measurement of the power transformation equipment, the refrigeration fan 22 is used for cooling the power transformation equipment, it should be noted that the refrigeration fan 22 in the embodiment is used for cooling treatment of the abnormal heating power transformation equipment; the refrigeration fan 22 can be replaced by other refrigeration modes according to actual temperature requirements, as long as the effect of cooling the equipment can be achieved.

[0027] Specifically, a control unit is used for receiving temperature measurement data of the infrared lens 21, and automatically starting or adjusting the working state of the refrigeration fan 22 according to the set temperature threshold.

[0028] Referring to Figures 2-4 , the support platform 12 comprises a base 13, a fence 14 arranged on the base 13 and a moving piece 15 arranged on the base 13; the base 13 is connected with the end of the lifting truck 11, the side wall of the base 13 is provided with a moving track, the fence 14 is provided with a baffle 141 close to one side of the push-pull plate 153, and a limit lock 142 is arranged on the fence 14.

[0029] In some embodiments, referring to Figure 5 , the moving piece 15 comprises a bottom plate 151, a roller 152 arranged on the bottom plate 151 and a push-pull plate 153 arranged on the bottom plate 151; the end of the bottom plate 151 is provided with a fence rod 154, the height of the fence rod 154 is less than the height of the fence 14, the end of the bottom plate 151 is provided with a roller shaft, the roller shaft is matched with the moving track, it should be noted that the function of the fence rod 154 is to cooperate with the fence 14 to protect the equipment at the end of the base 13 from falling off the end of the base 13 during movement, and the fence rod 154 adds an extra protection for this protection mode; it should be noted that the roller shaft at the end of the bottom plate 151 can move along the moving track on both sides of the base 13, but the roller shaft at the end of the bottom plate 151 is not separable from the base 13.

[0030] Specifically, referring toFigure 6 The end of the push-pull plate 153 is provided with a friction surface 155, the side of the push-pull plate 153 away from the bottom plate 151 is provided with a handle slot 156, the side of the push-pull plate 153 close to the bottom plate 151 is provided with a contact block 157, and the bottom end of the push-pull plate 153 is rotationally connected to the bottom plate 151 through a rotating shaft. It should be noted that when the friction surface 155 of the push-pull plate 153 faces upward, the push-pull plate 153 can be used to push and pull the bottom plate 151. When the friction surface 155 of the push-pull plate 153 faces downward, that is, faces the ground, the push-pull plate 153 can provide support force to the bottom plate 151. When loading and unloading the equipment, the friction surface 155 of the push-pull plate 153 is in contact with the ground, which increases the friction between the ground and the push-pull plate 153 and supports the bottom plate 151. At the same time, the push-pull plate 153 cooperates with the rollers 152 at the ends of the bottom plate 151, which can achieve the effect of simple loading and unloading of the equipment.

[0031] With reference to Figure 6 The contact block 157 on the push-pull plate 153 can be made of rubber material, so that it can adapt to the shape of the equipment when contacting the equipment, and at the same time can increase the friction between the equipment and the push-pull plate 153, reducing the shaking of the equipment during the movement of the lifting vehicle 11.

[0032] Further, with reference to Figure 3 and Figure 4 When the fence 14 is in the locked state, the bottom end of the baffle 141 is lower than the end of the push-pull plate 153, the end of the baffle 141 is higher than the end of the push-pull plate 153, the baffle 141 is in contact with the push-pull plate 153, that is, in the locked state, the baffle 141 and the push-pull plate 153 partially overlap and contact, and the baffle 141 and the push-pull plate 153 are in contact, so that the push-pull plate 153 is in contact with the equipment at the end of the bottom plate 151, thereby limiting the equipment at the end of the bottom plate 151, preventing the equipment from shaking left and right during the movement of the lifting vehicle 11, and reducing the risk of falling of the equipment from a high place.

[0033] The operation process is as follows: the initial state of the lifting vehicle 11 is set as the lowest height of the lifting vehicle 11, the bottom plate 151 is first pulled out of the base 13 through the push-pull plate 153 until the roller shaft at the end of the bottom plate 151 is moved from the end of the base 13 to the other end, it should be noted that the roller shaft at the end of the bottom plate 151 can move along the moving track on both sides of the base 13, but the roller shaft at the end of the bottom plate 151 cannot be separated from the base 13, then the push-pull plate 153 can be rotated counterclockwise by 180°, at this time the friction surface 155 at the end of the push-pull plate 153 is in contact with the ground, and the whole bottom plate 151 is in a state of tilting towards the ground, because a plurality of groups of rollers 152 are arranged at the end of the bottom plate 151, the device can be completely pushed to the end of the bottom plate 151, then the bottom plate 151 is lifted upwards, the push-pull plate 153 is rotated clockwise by 180°, at this time the bottom plate 151 can be pushed along the moving track of the base 13 by pushing the push-pull plate 153 to completely enter the base 13, then the limiting lock 142 of the fence 14 is closed, at this time the device is placed at the end of the base 13.

[0034] As an optional embodiment, the application further provides a maintenance method for a power transformation device, comprising a maintenance device, further comprising: first moving the lifting vehicle 11 to the power transformation device; then using the infrared lens 21 to measure the temperature of the power transformation device and transmitting the temperature data to the control unit; the control unit starts or adjusts the output of the refrigeration fan 22 according to the preset temperature threshold; and the temperature of the power transformation device is reduced to the normal working range by the refrigeration fan 22.

[0035] Specifically, when the control unit controls the output of the refrigeration fan 22, the refrigeration power of the refrigeration fan 22 is linearly adjusted according to the degree of temperature exceeding the set threshold, wherein when the temperature exceeds the set threshold in the range of 0-5℃, the refrigeration power is increased according to a preset first proportion; when the temperature exceeds the set threshold in the range of 5-10℃, the refrigeration power is increased according to a preset second proportion, and the second proportion is greater than the first proportion; and when the temperature exceeds the set threshold by more than 10℃, the refrigeration part operates at the maximum power, so as to realize precise control of the temperature of the power transformation device.

[0036] The operation process is as follows: after the device is placed at the end of the base 13, the lifting vehicle 11 is raised to an appropriate height by the remote control system, at this time the staff below the lifting vehicle 11 moves the lifting vehicle 11 to the device to be maintained by the remote control system, then the temperature of the power transformation device is measured by the infrared lens 21, at the same time, the control unit receives the temperature value of the device tested by the infrared lens 21, and controls whether the refrigeration fan 22 is started according to the preset threshold, at the same time, the control unit can adjust the output power of the refrigeration fan according to the temperature value tested by the infrared lens 21, until the temperature of the power transformation device is reduced to the normal range.

[0037] It should finally be pointed out that the methods and devices described in detail above are only embodiments, which the person skilled in the art can modify in different ways, without departing from the scope of the present invention.
