[0013] Working principle: first put the whole structure except the smart capacitor into the distribution box, align the mounting screws with the threaded holes on the side wall of the distribution box, and then use a hexagonal wrench to rotate the screw sleeve. When the screw sleeve rotates, it drives the driving gear to rotate. The driving gear drives the rotating shaft to rotate through the meshing transmission with the driven gear. When the rotating shaft rotates, the sliding rod is driven to rotate by the cooperation of the card slot and the card strip, thereby driving the mounting screw to rotate. Since the sliding rod also slides in the slide slot, the mounting screw can smoothly rotate and move from the slide slot, thereby completing the installation with the threaded holes on the side wall of the distribution box. According to this method, all the mounting screws are installed in the threaded holes on the side wall of the distribution box to complete the fixation of the external overall structure, and then the smart capacitor is placed in the first In a mounting seat, when the bottom of the smart capacitor contacts the support platform, the resistance block will be pressed down.

DETAILED DESCRIPTION

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0026] Example:

[0027] like Figure 1-6As shown, an embodiment of the present invention provides a new type of high-safety smart capacitor assembly for a distribution box, including two positioning plates 1, which have a connection and fixing function. The front and rear sides of the lower side of the end of the positioning plate 1 that is close to each other are welded with a lower sheet metal 2, and the upper surface of the lower sheet metal 2 is connected with several first mounting seats 3 by bolts for mounting smart capacitors 4. The surfaces of the first mounting seats 3 on the corresponding sides are all mounted with smart capacitors 4, and the four corners of the edge of the end of the positioning plate 1 that is away from each other are all mounted with second mounting seats 5 for mounting the overall structural frame. The bottoms of the ends of the positioning plates 1 that are close to each other are respectively welded to the two ends of the heat dissipation plate 8, and the surface of the heat dissipation plate 8 is provided with several heat dissipation holes 9 to increase the heat dissipation effect. The upper surface of the heat dissipation plate 8 is welded with a guide plate 10 at a position on one side near each heat dissipation hole 9, which diverts the airflow generated by the cross-flow fan 12 up and down, and the heat accumulated on the lower side is taken away from the heat dissipation hole 9. The airflow on the upper side completes the heat dissipation of the upper part of the smart capacitor and is discharged through the vent 13.

[0028] In this embodiment, the first mounting base 3 includes a base 301 and a U-shaped groove 302 arranged on the surface of the base 301. The base 301 is connected to the surface of the lower sheet metal part 2 by bolts. The interior of the U-shaped groove 302 is movably connected with a U-shaped clamping plate 303 for clamping the two ends of the bottom of the smart capacitor 4. The bottom wall of the U-shaped groove 302 is welded with a support platform 304 for supporting the placement of the smart capacitor 4.

[0029] Furthermore, a vertical groove 305 is provided in the longitudinal direction of the inner middle part of the support platform 304, and a resistance block 306 is slidably connected inside the vertical groove 305. The bottom end of the resistance block 306 is provided with a slope 307, and the slope 307 is matched with the straight groove 310 on the linkage plate 309. The bottom wall of the vertical groove 305 is fixedly connected with a second reset spring 312, which is used to reset the resistance block 306 after the smart capacitor 4 is taken out.

[0030] Furthermore, a transverse groove 308 is provided in the transverse axis direction inside the support platform 304, and a linkage plate 309 is slidably connected inside the transverse groove 308. One end of the linkage plate 309 is fixedly connected to the inner bottom side wall of the U-shaped clamp 303. Through the movement of the linkage plate 309, the U-shaped clamp 303 is linked to move, thereby clamping the bottom two ends of the smart capacitor 4. A straight slot 310 is provided in the middle of the linkage plate 309, and the other end of the linkage plate 309 is connected to the inner wall of the transverse groove 308 through a first reset spring 311, which is used to reset the linkage plate 309 after the smart capacitor 4 is taken out.

[0031] Specifically, the smart capacitor 4 is placed in the first mounting seat 3. When the bottom of the smart capacitor 4 contacts the support platform 304, the resistance block 306 is pressed down. When the resistance block 306 descends, the inclined surface 307 cooperates with the straight slot 310 to drive the linkage plate 309 to move in the transverse slot 308, thereby driving the U-shaped clamping plate 303 to move in the U-shaped slot 302, thereby clamping the bottom of the smart capacitor 4. According to this method, all smart capacitors 4 are placed on the corresponding first mounting seat 3 to complete the installation. During maintenance and disassembly, the structure can be removed according to the installation steps, which is easy to operate.

[0032] Furthermore, the second mounting base 5 includes a positioning block 501 and a screw sleeve 502. One end of the positioning block 501 is welded to the surface of the positioning plate 1. The screw sleeve 502 is movably connected to the upper surface of the positioning block 501. The bottom end of the screw sleeve 502 is fixedly connected to a driving gear 503. The interior of the positioning block 501 is movably connected to a rotating shaft 504. One side of the outer surface of the rotating shaft 504 is fixedly connected to a driven gear 505. The bottom side of the driving gear 503 is meshed with the upper side of the driven gear 505. Rotating the screw sleeve 502 will drive the driving gear 503 to rotate, thereby driving the driven gear 505 to rotate. Both the driving gear 503 and the driven gear 505 are bevel gears.

[0033] Furthermore, a slide groove 506 is provided inside the rotating shaft 504, and a slide rod 507 is slidably connected inside the slide groove 506. The outer end of the slide rod 507 is welded with a mounting screw 510, which corresponds to the threaded hole on the inner wall of the distribution box. The inner walls of the upper and lower ends of the slide groove 506 are provided with a card groove 508, and the upper and lower ends of the slide rod 507 are welded with a card strip 509. The card strip 509 is slidably connected to the inside of the card groove 508 on the corresponding side, so that the slide rod 507 can be driven to rotate when the rotating shaft 504 rotates, and at the same time, it does not hinder the slide rod 507 from sliding left and right in the slide groove 506.

[0034] Specifically, the entire structure except the intelligent capacitor 4 is placed in the distribution box, and the mounting screws 510 are aligned with the threaded holes on the side wall of the distribution box. Then, the screw sleeve 502 is rotated with a hexagonal wrench. When the screw sleeve 502 rotates, it drives the driving gear 503 to rotate. The driving gear 503 drives the rotating shaft 504 to rotate through the meshing transmission with the driven gear 505. When the rotating shaft 504 rotates, the sliding rod 507 is driven to rotate by the cooperation of the card slot 508 and the card strip 509, thereby driving the mounting screws 510 to rotate. Since the sliding rod 507 also slides in the slide groove 506, the mounting screws 510 can be smoothly rotated and moved in the slide groove 506, thereby completing the installation with the threaded holes on the side wall of the distribution box. According to this method, all the mounting screws 510 are installed in the threaded holes on the side wall of the distribution box to complete the fixation of the external overall structure. The disassembly is similar. The structure is ingenious and the operation is simple.

[0035] Furthermore, the bottom of the rear side of the end of the positioning plate 1 that is close to each other is welded to the two ends of the rib plate 11 for connection and fixing. A cross-flow fan 12 is installed at the end of the rib plate 11 close to the smart capacitor 4, which is the main heat dissipation structure. A plurality of air vents 13 are provided on the surface of the positioning plate 1, which are interconnected with the heat dissipation windows on the distribution box to facilitate heat dissipation. Upper sheet metal parts 6 are welded on the front and rear sides of the upper side of the end of the positioning plate 1 that is close to each other, which facilitates the carrying structure and improves stability. A controller 7 is placed above the smart capacitor 4 for controlling the working state of the smart capacitor 4.

[0036] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
