[0007] Furthermore, the automatic lifting bracket includes a ball screw, a support base and a sliding connection base, the ball screw is arranged on the support base, the bottom center of the sliding connection base is cooperatively connected with the ball screw, the end of the ball screw is used to connect with the driving motor, the air inlet baffle is connected to the side of the sliding connection base, and the air outlet baffle is connected above the sliding base.

[0008] Furthermore, two sets of sliding guide rails are arranged on the support base, and a plurality of sliding blocks cooperating with the sliding guide rails are arranged below the sliding connection base.

[0009] The advantages of the invention compared with the prior art are:

[0010] The present invention adopts a combination of a supporting bottom plate, electrical equipment, a clamping and fixing hole, an automatic lifting bracket, a driving motor, an air inlet baffle plate, and an air outlet baffle plate. When the outdoor weather is clear and the working temperature of the electrical equipment is high, the driving motor is started to work, and the driving motor drives the automatic lifting bracket to descend, so that the air inlet baffle plate and the air outlet baffle plate are lowered, so that the air inlet and air outlet on the protective shell of the electrical equipment can be opened, and the above-mentioned electrical equipment protective shell is adjusted to an outdoor heat dissipation state, so that the heat on the electrical equipment can be dissipated in time, and the working state of the electrical equipment is avoided from being affected by the internal temperature being too high.

[0029] Embodiment 1:

[0030] like Figure 1 , Figure 4 , Figure 5 , Figure 7 As shown, when the present invention is in use, when the outdoor weather is clear and the operating temperature of the electrical equipment is high, when the electrical equipment has been running for a long time and its internal temperature is high, the drive motor 7 is started to work, and the drive motor 7 drives the automatic lifting bracket 6 to move downward, wherein the automatic lifting bracket 6 includes a ball screw 13, a support base 14 and a sliding connection base 15. When the drive motor 7 starts to work, it drives the ball screw 13 to rotate clockwise, and the rotation of the ball screw 13 drives the sliding connection base 15 to move downward. At the same time, the sliding connection base 15 drives the air inlet baffle 8 and the air outlet baffle 9 to move downward. After the air inlet baffle 8 moves downward, the air inlet 10 on the electrical equipment protective shell 5 is opened, and after the air outlet baffle 9 moves downward, the air outlet 11 on the electrical equipment protective shell 5 is opened, and the cooling fan 12 is started to dissipate the heat of the electrical equipment protective shell 5 to prevent the internal temperature of the electrical equipment protective shell 5 from being too high and affecting the normal operation of the electrical equipment.

[0031] When the outdoor weather is cloudy and rainy, in order to prevent rainwater from entering the interior of the electrical equipment protective shell 5, it is necessary to close the air inlet 10 and the air outlet 11 on the electrical equipment protective shell 5, start the drive motor 7 to start working, and the drive motor 7 drives the automatic lifting bracket 6 to move upward, wherein the automatic lifting bracket 6 includes a ball screw 13, a supporting base 14 and a sliding connection base 15.

Among them, the grounding component is a grounding conductor, and the insulating pad is an insulating rubber pad. How to achieve the grounding of the above-mentioned electrical equipment is a well-known and commonly used technical means by those skilled in the art, and the applicant will not elaborate on it.

A guide column 29 is provided at the inner end of the adjusting button 28, and a limiting buckle 30 is extended upward on its side. The guide column 29 on the adjusting button 28 is inserted into the first limiting spring 24, and the second limiting spring 25 is sleeved on the fixed connecting column 27.

[0045] The top of the outer shell 23 is provided with a rectangular hole 32, and circular holes 33 are provided on both sides thereof. The bottom end of the first limiting connection component 21 on the supporting base plate 1 is provided with a snap-fitting groove 31. The first limiting connection component 21 is pressed into the outer shell 23 from the rectangular hole 32, and the snap-fitting groove 31 at the bottom end cooperates and locks with the limiting buckle 30 in the outer shell 23.

[0046] During operation of this embodiment, when it is necessary to open the protective housing 5 of the electrical equipment, the adjusting button 28 can be directly pressed inward by hand, and the adjusting button 28 pushes and squeezes the first limit spring 24 inward. At the same time, the adjusting button 28 drives the limit buckle 30 on its inner side to move inward. At this time, the engaging groove 31 at the bottom end of the first limit connection part 21 is disengaged from the restraint of the upper limit buckle 30 of the second limit connection part 22, and at the same time, the second limit spring 25 in a compressed state restores its original state, and gives an upward elastic force to the second limit connection part 22 when the first limit connection part 21 is bounced up, so that the protective housing 5 of the electrical equipment and the supporting base plate 1 can be quickly separated.

[0047] Since one side of the electrical equipment protection housing 5 is rotatably connected to the support base plate 1 through a rotating shaft, after the electrical equipment protection housing 5 and the support base plate 1 are separated, the electrical equipment protection housing can be directly opened by hand, which is simple to operate and has strong practicality.
