When the first sliders slide, they will compress the compression spring. Under the elastic action of the compression spring, the clamping plate always closely adheres to the electrical junction box, improving the clamping stability of the electrical junction box, preventing the electrical junction box from shifting. At the same time, the anti-slip stickers on the clamping plate and the anti-slip pads on the supporting plate can play an anti-slip role, further improving the clamping stability of the electrical junction box.

[0029] The embodiments of the present invention will be described in detail below with reference to the drawings.

[0031] Refer to Figures 2 - 5, it is further obtained that the installation mechanism 3 includes two longitudinal support rods 301. Between the two longitudinal support rods 301, two transverse support rods 302 are fixedly arranged. Between the two transverse support rods 302, a support plate 303 is fixedly arranged. A plurality of positioning holes 305 are formed in the transverse support rods 302. A bidirectional lead screw 306 is rotatably arranged between the two longitudinal support rods 301. Two sliding sleeves 308 are slidably sleeved on the transverse support rods 302. A connecting frame 312 is fixedly connected between the two sliding sleeves 308 on the two transverse support rods 302. A nut sleeve 313 threadedly connected to the bidirectional lead screw 306 is arranged through the connecting frame 312. A fixing hole 309 adapted to the positioning hole 305 is formed in the sliding sleeve 308. A fixing plate 314 is fixedly arranged on the sliding sleeve 308. A clamping plate 321 is arranged on one side of the fixing plate 314; one end of the bidirectional lead screw 306 rotatably penetrates through the longitudinal support rod 301 and is fixedly connected with a hand-tightening block 307. The bidirectional lead screw 306 rotatably penetrates through the support plate 303. An anti-slip pad 304 is fixedly arranged on the support plate 303. A groove 315 is formed on one side of the fixing plate 314. A first sliding rod 316 is fixedly arranged in the groove 315.

The compression springs 320 are fixedly arranged between the first sliding blocks 318 and the groove 315. A bolt 310 is inserted into the fixing hole 309. The bolt 310 passes through the positioning hole 305 corresponding to the fixing hole 309 and is threadedly connected with a nut 311. An anti-slip sticker 322 is fixedly arranged on the other side of the clamping plate 321. A connecting plate 323 is fixedly connected between the front and rear clamping plates 321.

[0032] Specifically, when the clamping plate 321 fixedly clamps the electrical junction box 1, the clamping plate 321 is squeezed to rotate the first hinge rod 319 and push the two first sliders 318 to slide towards each other along the surface of the first slide rod 316. When the first slider 318 slides, it will squeeze the compression spring 320. Under the elastic action of the compression spring 320, the clamping plate 321 always closely adheres to the electrical junction box 1, improving the clamping stability of the electrical junction box 1, preventing the electrical junction box 1 from shifting. At the same time, the anti-slip stickers 322 on the clamping plate 321 and the anti-slip pads 304 on the supporting plate 303 can play an anti-slip role, further improving the clamping stability of the electrical junction box 1; by rotating the hand-twisting block 307 to rotate the bidirectional lead screw 306, under the thread action of the nut sleeve 313 and the bidirectional lead screw 306, the two connecting frames 312 drive the two sets of sliding sleeves 308 to move towards each other until the two sets of clamping plates 321 closely adhere to the two end surfaces of the electrical junction box 1. Then, insert the bolt 310 into the fixing hole 309 and pass through the corresponding positioning hole 305 and use the nut 311 for fixation, so that the sliding sleeve 308 can be locked on the cross support rod 302, thereby completing the fixation of the position of the clamping plate 321, enabling the electrical junction box 1 to be fixed on the supporting plate 303, and this bracket is applicable to electrical junction boxes 1 of different sizes, improving the versatility of the bracket.

[0033] Refer to Figure 2 , Figure 5 and Figure 6 , it can be further obtained that the shock-absorbing mechanism 4 includes a damping rod 402 arranged between the vertical support rod 301 and the base 2. A shock-absorbing spring 403 is sleeved on the damping rod 402. Two mounting plates 404 are fixedly arranged on the base 2. A second slide rod 405 is fixedly arranged between the two mounting plates 404. Two second sliders 406 are slidably sleeved on the second slide rod 405. Hinge blocks 407 are fixedly arranged on both the second sliders 406 and the bottom of the supporting plate 303. A second hinge rod 408 is fixedly arranged between the two hinge blocks 407. A buffer spring 409 fixedly arranged between the two second sliders 406 is sleeved on the second slide rod 405. Shock-absorbing pads 401 are fixedly arranged on both the bottom of the vertical support rod 301 and the top of the base 2.

A rubber pad 410 is fixedly arranged on the bottom of the base 2.

[0034] Specifically, through the settings of the damping rod 402 and the shock-absorbing spring 403, the vibration force generated by external forces or factors such as earthquakes during the use of the electrical junction box 1 can be effectively absorbed and dispersed, effectively reducing the vibration amplitude of the electrical junction box 1. When the supporting plate 303 vibrates, the second hinge rod 408 can push or pull the two second sliders 406. The second sliders 406 slide along the surface of the second slide rod 405 and compress or stretch the buffer spring 409. Under the elastic potential energy of the buffer spring 409, the vibration force can be further gradually weakened, so as to achieve the effect of shock absorption and protection for the electrical junction box 1.

[0035] Embodiment 2 Combined with Figures 1 - 6 , an installation method of a quick-installation shock-absorbing bracket for an electrical junction box in a thermal power plant provided by the present invention includes: Place the electrical junction box 1 on the supporting plate 303. Then, rotate the hand-tightening block 307 to make the bidirectional lead screw 306 rotate. Under the thread action of the screw sleeve 313 and the bidirectional lead screw 306, the two connecting frames 312 drive the two groups of sliding sleeves 308 to move towards each other. The sliding sleeves 308 slide along the surface of the cross support rod 302 until the two groups of clamping plates 321 closely adhere to the two end surfaces of the electrical junction box 1. Then, insert the bolt 310 into the fixing hole 309 on the sliding sleeve 308, and pass the bolt 310 through the positioning hole 305 on the cross support rod 302 corresponding to the fixing hole 309 and use a nut 311 to fix it, so that the sliding sleeve 308 can be locked on the cross support rod 302, thereby completing the fixation of the clamping plate 321 and enabling the electrical junction box 1 to be fixed on the supporting plate 303, completing the installation of the electrical junction box 1; When the clamping plate 321 clamps, the contact surface between the clamping plate 321 and the electrical junction box 1 is squeezed, causing the first hinge rod 319 in the groove 315 to rotate and push the two first sliders 318 to slide towards each other along the surface of the first slide rod 316. When the first sliders 318 slide, they will compress the compression spring 320, so that the clamping plate 321 always closely adheres to the electrical junction box 1 under the elastic action of the compression spring 320, improving the clamping stability of the electrical junction box 1 and preventing the electrical junction box 1 from shifting. At the same time, the anti-slip stickers 322 on the clamping plate 321 and the anti-slip pads 304 on the supporting plate 303 can play an anti-slip role, further improving the clamping stability of the electrical junction box 1; When the electrical junction box 1 is vibrated due to external forces or factors such as earthquakes during use, the vibration force will act on the supporting plate 303. Through the settings of the damping rod 402 and the shock-absorbing spring 403, the vibration energy can be effectively absorbed and dispersed, thereby reducing the vibration amplitude of the electrical junction box 1. The shock pads 401 provided at both ends of the shock-absorbing spring 403 can increase the contact area and the shock-absorbing effect. When the supporting plate 303 vibrates, the second hinge rod 408 can push or pull the two second sliders 406. The second sliders 406 slide along the surface of the second slide rod 405 and squeeze or stretch the buffer spring 409. Under the elastic potential energy of the buffer spring 409, the vibration force can be further gradually weakened, so as to achieve the effect of shock absorption and protection for the electrical junction box 1. At the same time, through the setting of the rubber pad 410 at the bottom of the base 2, the friction between the base 2 and the ground can be increased, preventing the bracket from sliding and improving the stability of the electrical junction box 1 after installation.

The installation method of a quick-installation shock-absorbing bracket for an electrical junction box in a thermal power plant according to any one of claims 1 to 9, characterized in that, Including: Place the electrical junction box (1) on the supporting plate (303), rotate the bidirectional lead screw (306), under the threaded action of the screw sleeve (313) and the bidirectional lead screw (306), the two connecting frames (312) drive the two sets of sliding sleeves (308) to move towards each other, and the sliding sleeves (308) slide along the surface of the cross support rod (302) until the two sets of clamping plates (321) are tightly attached to the two end surfaces of the electrical junction box (1). Then, the sliding sleeves (308) can be locked on the cross support rod (302), thereby completing the fixation of the clamping plates (321), enabling the electrical junction box (1) to be fixed on the supporting plate (303), and completing the installation of the electrical junction box (1). When the clamping plate (321) clamps, the contact surface between the clamping plate (321) and the electrical junction box (1) is squeezed, causing the clamping plate (321) to closely adhere to the electrical junction box (1) to prevent the electrical junction box (1) from shifting. When the electrical junction box (1) vibrates due to external forces or seismic factors during use, the vibration force acts on the supporting plate (303). Through the settings of the damping rod (402) and the shock-absorbing spring (403), the vibration energy can be absorbed and dispersed. Moreover, when the supporting plate (303) vibrates, the second hinge rod (408) can push or pull the two second sliders (406), and the second sliders (406) slide along the surface of the second slide rod (405) and squeeze or stretch the buffer spring (409). Under the elastic potential energy of the buffer spring (409), the vibration force can be gradually weakened, thereby achieving the effect of shock absorption and protection for the electrical junction box (1).
