[0024] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0025] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0026] like Figure 1 , 2 As shown, an improved inverter installation structure is provided with a protective box 1, a sliding unit 2 is provided on the inner bottom plate of the protective box 1, the sliding unit 2 includes a slide 21 installed on the bottom plate of the protective box 1, a slider 22 is provided on the slide 21, a horizontal support plate 3 is provided on the slider 22, the horizontal support plate 3 is connected to a sliding drive (not shown in the figure), a vertical support plate 4 is provided on the horizontal support plate 3, the vertical support plate 4 is located close to the back plate of the protective box 1, and mounting holes 5 are provided on both the horizontal support plate 3 and the vertical support plate 4.

[0027] Specifically, the sliding unit 2 can drive the horizontal support plate 3 and the vertical support plate 4 to move forward or backward along the slideway direction. The sliding drive (not shown in the figure) is a driving cylinder. The sliding drive can drive the horizontal support plate 3 to move back and forth. The frequency converter can be installed on both the horizontal support plate 3 and the vertical support plate 4. By setting the horizontal support plate 3 and the vertical support plate 4, two different installation platforms are provided, so that the frequency converter can be flexibly installed according to the needs of the actual application scenario. That is, when the frequency converter needs to be installed horizontally, it can be fixed on the horizontal support plate 3; when it needs to be installed vertically, it can be fixed on the vertical support plate 4 to adapt to more installation scenarios. When the frequency converter needs to be repaired, the support plate is moved to the door position of the protective box 1 through the sliding drive. There is no need to enter the interior of the protective box 1 for disassembly operation. The frequency converter can be disassembled or repaired at the door, which greatly improves the work efficiency and avoids the problem of inconvenient use of maintenance tools in the limited space of the protective box 1.

[0028] like Figure 1As shown, a cooling fan 11 is arranged on the top plate of the protection box 1 , and ventilation holes 12 are arranged on the side plates on both sides of the protection box 1 .

[0029] Specifically, the cooling fan 11 arranged on the top plate of the protective box 1 and the vents 12 on the side plates together constitute an effective heat dissipation system. The main function of the cooling fan 11 is to extract the hot air inside the protective box 1 and introduce fresh cold air from the outside into the box through the vents 12 to form a circulation, thereby reducing the temperature inside the box and preventing the inverter from overheating and causing abnormal operation or communication failure. The combination of the cooling fan 11 and the vents 12 can ensure that the equipment always remains within the appropriate operating temperature range, thereby ensuring its stable operation and the reliability of communication transmission, and extending the service life of the equipment.

[0030] like Figure 1 , 3 As shown, the protective box 1 is also provided with a handle 13 to facilitate opening the box for inspection and maintenance.

[0031] like Figure 4 , 5 As shown, a buffer unit 6 is provided on both the horizontal support plate 3 and the vertical support plate 4, and the buffer unit 6 includes a buffer connecting rod 61, a buffer spring 62 is provided on the outer surface of the buffer connecting rod 61, a buffer pad 63 is provided at one end of the buffer connecting rod 61, and a positioning block 64 is provided at the other end, and the positioning block 64 is placed in a buffer cavity 65, and the outlet diameter of the buffer cavity 65 is smaller than the diameter of the positioning block 64.

[0032] Specifically, the buffer pad 65 is in contact with the frequency converter, and the positioning block 64 is placed in the buffer cavity 65 and reciprocates along the buffer cavity 65. Since the outlet diameter of the buffer cavity 65 is smaller than the diameter of the positioning block 64, the positioning block 64 is confined in the buffer cavity 65, ensuring that the positioning block 64 will not fall off from the buffer cavity 65. The buffer spring 62 is located on the outer surface of the buffer connecting rod 61. When the frequency converter is locked on the horizontal support plate 3 or the vertical support plate 4, the buffer spring 62 will be compressed, thereby applying a certain pressure to the frequency converter through the buffer pad 63. The buffer pad 63 is in close contact with the frequency converter, and the buffer pad 63 can effectively absorb the vibration of the frequency converter to prevent the bolts from loosening or the frequency converter from falling off due to vibration during the operation of the equipment.

[0033] The present application discloses an improved inverter installation structure, which is provided with a protection box 1, a sliding unit 2 is provided on the bottom plate inside the protection box 1, a horizontal support plate 3 is provided on the slider 22, and a vertical support plate 4 is provided on the horizontal support plate 3. Two different installation platforms are provided by providing the horizontal support plate 3 and the vertical support plate 4, so that the inverter can be flexibly installed according to the needs of the actual application scene. That is, when the inverter needs to be installed horizontally, it can be fixed on the horizontal support plate 3; when it needs to be installed vertically, it can be fixed on the vertical support plate 4 to adapt to more installation scenes; by providing the sliding unit 2, the horizontal support plate 3 and the vertical support plate 4 can be driven to move forward or backward along the slideway direction. When the inverter needs to be repaired, the support plate is moved to the door position of the protection box 1 by the sliding driver, and there is no need to enter the interior of the protection box 1 for disassembly operation. The inverter can be disassembled or repaired at the door, which greatly improves the work efficiency and avoids the problem of inconvenience in using repair tools in the limited space of the protection box 1.
