[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0021] The utility model provides Figures 1 to 3 A mobile assembly of a high-voltage dynamic reactive power compensation device shown in the figure comprises an equipment box 1, a reactive power compensation device box 2 is fixed on the top of the equipment box 1, a driving shaft 3 and a driven shaft 4 are rotatably connected to the two sides of the inner cavity of the equipment box 1 through bearings, two groups of support plates 5 are movably arranged on the outer sides of the driving shaft 3 and the driven shaft 4, a moving wheel 6 is rotatably connected to the inner side of the support plate 5 away from the driving shaft 3 and the driven shaft 4 through a movable shaft, four groups of through grooves 7 are opened at the bottom of the equipment box 1, the support plate 5 and the moving wheel 6 pass through the through grooves 7 and extend downward, a worm 8 is rotatably connected to one side of the inner cavity of the equipment box 1 through a bearing, a worm wheel 9 is fixed on the outer side of the driving shaft 3, and the worm wheel 9 is meshed with the side facing the worm 8;

[0022] The worm gear 9 is driven to rotate by the worm gear 8, and then the worm gear 9 drives the driving shaft 3 to rotate, and the driving shaft 3 drives the support plate 5 fixed on the outside to deflect, and then the support plate 5 on the driving shaft 3 drives the support plate 5 on the driven shaft 4 to deflect through the connecting rod 11, thereby synchronously driving the four groups of support plates 5 to deflect, so that the moving wheel 6 can pass through the through slot 7 and move into the bottom of the equipment box 1 and support the equipment box 1. At the same time, the worm gear 9 and the worm gear 8 have a self-locking function, which can prevent the driving shaft 3 and the driven shaft 4 from rotating in the opposite direction, causing the moving wheel 6 to retract into the equipment box 1. The operating device only needs to rotate the worm gear 8 from one side of the reactive compensation device box 2, which is convenient and quick.

[0023] A support rod 10 is fixed to the outer side of the support plate 5, and a connecting rod 11 is movably connected to the outer side of the support rod 10. The setting of the support rod 10 facilitates the connection of the connecting rod 11, and the connecting rod 11 is used to synchronously drive the driving shaft 3 and the driven shaft 4 to rotate.

[0024] Limiting grooves 12 are provided on both sides of the front and back sides of the inner cavity of the equipment box 1. The support rod 10 extends to the inner cavity of the limiting groove 12 on the side away from the support plate 5 and slides in the inner cavity of the limiting groove 12. Through the setting of the limiting groove 12, the support rod 10 can be limited to ensure the stable deviation of the support plate 5 and the moving wheel 6 and prevent the support plate 5 from bending.

[0025] A receiving groove 13 is provided on one side of the equipment box 1 close to the worm 8. One end of the worm 8 passes through the inner cavity of the receiving groove 13 and is provided with a connecting hole 14. The provision of the receiving groove 13 facilitates the storage of the worm 8 that passes through the equipment box 1 to prevent the worm 8 from affecting the reactive compensation device box 2 and the equipment box 1. The cooperation of the connecting hole 14 facilitates the external connection of an operating rod to the outside of the worm 8 to extend the length of the worm 8 and facilitate the rotation of the worm 8.

[0026] A limiting ring 15 is fixed on the outside of the support rod 10, and the limiting ring 15 is located on the front and rear sides of the connecting rod 11. The setting of the limiting ring 15 facilitates the limiting of the connecting rod 11 to prevent the connecting rod 11 from shaking on the outside of the support rod 10, causing excessive wear of the connecting rod 11, so as to prevent the connecting rod 11 from breaking and being unable to move on the driven shaft 4.

[0027] Limiting holes 16 are provided on the front and back of the equipment box 1, and a positioning hole 17 is provided on the outer side of the support plate 5. A positioning pin 18 is inserted into the inner cavity of the limiting hole 16. The opposite end of the positioning pin 18 passes through the inner cavity of the equipment box 1 and is engaged with the positioning hole 17. The positioning pin 18 passes through the limiting hole 16 and the positioning hole 17, so that the support plate 5 installed on the driven shaft 4 can be limited to prevent the connecting rod 11 from breaking. The driven shaft 4 cannot be restricted from rotating arbitrarily, causing the moving wheel 6 connected to the driven shaft 4 to retract back into the equipment box 1, resulting in the balance of the equipment box 1 and the reactive power compensation device box 2.

[0028] One end of the worm 8 away from the connecting hole 14 is movably mounted with a mounting seat 19 through a bearing. The mounting seat 19 is fixed to the bottom of the inner cavity of the equipment box 1. Through the setting of the mounting seat 19, the worm 8 is conveniently supported to ensure the engagement of the worm 8 with the worm wheel 9, thereby ensuring the continuity of the drive to prevent the rotating worm 8 from failing to effectively and timely drive the worm wheel 9.

[0029] A handle 20 is provided on the outside of the reactive compensation device box 2, and a protective pad is embedded on the outside of the handle 20. The setting of the handle 20 makes it convenient to support the reactive compensation device box 2 when the worm 8 is rotated to prevent the reactive compensation device box 2 and the equipment box 1 from tipping over.

[0030] During specific use, when it is necessary to move the static reactive power compensation device box 2, a tool is inserted into the connecting hole 14 to rotate the worm 8, which drives the worm wheel 9 to rotate and drives the drive shaft 3 to rotate. Then the drive shaft 3 drives the bottom support plate 5 to deflect downward, and at the same time, the support plate 5 drives the driven shaft 4 to rotate through the connecting rod 11, so that the moving wheels 6 installed on the four groups of support plates 5 pass through the through grooves 7 and move downward to support and lift the equipment box 1. Then, the positioning pin 18 is inserted into the limit hole 16 and connected with the positioning hole 17 to ensure that the drive shaft 3 and the driven shaft 4 rotate synchronously, and then the reactive power compensation device box 2 and the equipment box 1 can be moved.

[0031] Although 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 the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
