Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figures 1 to 5 As shown, an outdoor high-voltage vacuum circuit breaker comprises a U-shaped base 1, a high-voltage vacuum circuit breaker body 2 is fixedly mounted on the upper end surface of the U-shaped base 1, two round rods 3 are connected to the inner side surface of the U-shaped base 1, a first slide seat 4 and a second slide seat 5 are slidably connected to the outer surfaces of the two round rods 3, two first connecting springs 7 are connected between the first slide seat 4 and the second slide seat 5, one side of the first slide seat 4 and the second slide seat 5 are fixedly connected to a positioning plate 6, through the installation and use of the first slide seat 4 and the second slide seat 5, the two slide seats with elastic force can stably move back and forth on the two round rods 3, so as to adjust the distance between the two positioning plates 6, so as to facilitate the flexible fixing of outdoor high-voltage vacuum circuit breakers of different sizes;

[0028] The U-shaped base 1 is internally rotatably connected to a bidirectional threaded rotating rod 9, and the outer surfaces of the bidirectional threaded rotating rod 9 are respectively threadedly connected to two threaded pressure plates 10. A connecting plate 12 is installed on the upper end surface of the U-shaped base 1, and a driven gear 14 is installed on the outer surface of the bidirectional threaded rotating rod 9. The right end surface of the connecting plate 12 is rotatably connected to a gear rotating rod 13, and the gear rotating rod 13 and the driven gear 14 are meshed with each other.

[0029] The upper end surfaces of the two positioning plates 6 are threadedly connected with two positioning bolts 8.

Through the setting of the limit rods 11, the limit rods 11 can be used to limit the moving trajectory of the two threaded pressure plates 10, so that the two threaded pressure plates 10 can move back and forth smoothly, so as to adaptively adjust the distance between the two positioning plates 6.

[0030] Side handles 16 are installed at both ends of the U-shaped base 1. The two side handles 16 can be used to carry the entire high-voltage vacuum circuit breaker so that the high-voltage vacuum circuit breaker can be moved to a designated installation location. Two support plates 17 are fixedly connected to both sides of the U-shaped base 1. The upper end surfaces of the four support plates 17 are threadedly connected with fastening bolts 18. The lower sides of the fastening bolts 18 penetrate the support plates 17 and extend to the lower end surfaces of the support plates 17. Support circular plates 19 are installed on the lower end surfaces of the four fastening bolts 18. The support circular plates 19 are used to adjust the height of the U-shaped base 1.

The second slide 5 is located on the right side of the first slide 4. The left side of the gear rotating rod 13 passes through the connecting plate 12 and extends to the left end face of the connecting plate 12. A fixed handwheel 15 is fixedly installed on the left end face of the gear rotating rod 13.

[0034] The upper end surfaces of the two positioning plates 6 are both clamped with L-shaped plug plates 111, and the lower end surfaces of the two L-shaped plug plates 111 are installed with sealing boxes 222. The sealing boxes 222 are used to protect the positioning bolts 8. Through the installation and use of the L-shaped plug plates 111 and the sealing boxes 222, the L-shaped plug plates 111 are clamped onto the L-shaped plug plates 111. At this time, the L-shaped plug plates 111 will drive the sealing boxes 222 to cover the positioning bolts 8 at the positioning plates 6 to prevent the positioning bolts 8 from rusting when encountering water.

[0035] The working principle of an outdoor high-voltage vacuum circuit breaker provided by the utility model is as follows:

[0036] By rotating the four fastening bolts 18 respectively, the fastening bolts 18 will drive the supporting circular plates 19 to move downward, so that the four supporting circular plates 19 can raise the height of the U-shaped base 1, and then the fixed hand wheel 15 is rotated, and the fixed hand wheel 15 can drive the gear rotating rod 13 to rotate, and the gear rotating rod 13 can drive the two-way threaded rotating rod 9 at the driven gear 14 to rotate, and then the two threaded pressing plates 10 on the two-way threaded rotating rod 9 will move relatively, and the two threaded pressing plates 10 will simultaneously squeeze the first slide 4 and the second slide 5 with elastic force to move, so that the two positioning plates 6 can flexibly adjust the spacing to adapt to installation plates of different sizes, so that the outdoor high-voltage vacuum circuit breaker can be fixed on the installation plate at a high position, thereby improving the flexibility of outdoor high-voltage vacuum circuit breaker installation;

[0037] By pulling the side plate 27, the side plate 27 will drive the limiting slide bar 25 equipped with the second connecting spring 26 to be compressed, and then the U-shaped frame 21 will be clamped into the mounting block 20, and then the side plate 27 will be released. At this time, the limiting slide bar 25 with elastic force can further clamp and fix the U-shaped frame 21, and then the U-shaped frame 21 will drive the guide top plate 22 and the rain shield 23 to be clamped and installed above the entire high-voltage vacuum circuit breaker body 2, and then the guide top plate 22 and the rain shield 23 can be used for rain protection and sunshade, so as to extend the service life of the outdoor high-voltage vacuum circuit breaker.

Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
