DETAILED DESCRIPTION

[0030] 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.

[0031] See also Figure 1-8 The utility model provides a technical solution: a mobile indoor high-voltage vacuum circuit breaker, including a mobile box 1, a mobile wheel 2, a bottom plate 3, a movable bracket 4, a side block 5, a high-voltage vacuum circuit breaker body 6, a side plate 7, a mounting mechanism 8, a protrusion 9, a fixing sleeve 10, a connecting plate 11, a first spring 12, a movable rod 13, a fixing plate 14, a limiting plate 15, a second spring 16, a limiting column 17, a movable column 18 and a fixing cap 19.

[0032] When using the mobile indoor high voltage vacuum circuit breaker, Figure 1 , Figure 5 and Figure 6 As shown, a bottom plate 3 is provided inside the movable box 1. First, the high-voltage vacuum circuit breaker body 6 is directly placed on the upper end of the bottom plate 3, and the left and right sides of the lower end of the high-voltage vacuum circuit breaker body 6 are fixedly connected with side plates 7. Combined with the setting of the mounting mechanism 8, the mounting mechanism 8 includes a convex block 9 for positioning, a fixed sleeve 10 sleeved on the outside of the convex block 9, a connecting plate 11 fixedly connected to the front and rear ends of the fixing sleeve 10, a first spring 12 provided on the side of the connecting plate 11 away from the fixing sleeve 10, and a movable rod 13 fixedly connected to the movable end of the first spring 12. By pulling the movable rod 13, the movable rod 13 slides between the connecting plate 11, and the movable rod 13 squeezes the first spring 12, so that the first spring 12 undergoes elastic deformation;

[0033] Then, the fixing sleeve 10 is sleeved on the outside of the protrusion 9, and the fixing sleeve 10 is fitted on the upper end of the side plate 7 to press and fix the side plate 7. At the same time, the movable rod 13 is aligned with the fixing plate 14, and the connecting plate 11 and the fixing plate 14 are fitted. Then, the movable rod 13 is released, and the first spring 12 restores its elastic deformation, pushing the movable rod 13 and the connecting plate 11 to slide, and the movable rod 13 and the fixing plate 14 are engaged, so as to facilitate the limiting of the fixing sleeve 10 and the protrusion 9, realize the disassembly and assembly between the high-voltage vacuum circuit breaker body 6 and the bottom plate 3, and facilitate the disassembly and maintenance of the high-voltage vacuum circuit breaker body 6. After the installation is completed, it is as follows Figure 1 The state shown, then push the movable box 1 to drive the movable wheel 2 to move on the ground, and drive the high-voltage vacuum circuit breaker body 6 to the corresponding use position indoors;

[0034] In addition, after use, the mobile box 1 drives the high-voltage vacuum circuit breaker body 6 to move to the storage position, and the mobile box 1 drives the high-voltage vacuum circuit breaker body 6 to move to the storage position. Figure 2 , Figure 4 and Figure 7 As shown, by rotating the fixing cap 19 threadedly connected to the outer surface of the limiting column 17, the fixing cap 19 pushes the movable column 18 to slide with the limiting column 17. At this time, the movable column 18 drives the limiting plate 15 to slide with the movable box 1. The limiting plate 15 squeezes the second spring 16, so that the second spring 16 is elastically deformed, and the limiting plate 15 is separated from the lower end of the movable bracket 4. Then, the movable bracket 4 is slowly moved downward, and the movable bracket 4 slides with the side block 5. The movable bracket 4 drives the bottom plate 3 to move to the bottom of the movable box 1, and the high-voltage vacuum circuit breaker body 6 can be stored in the movable box 1, as shown in the figure. Figure 2 The state shown is then reversed, and the fixing cap 19 is rotated to release the limit between the movable column 18 and the limit column 17. At this time, the second spring 16 restores its elastic deformation, driving the limit plate 15 to engage with the corresponding position of the upper end of the movable bracket 4, thereby facilitating the limit between the bottom plate 3 and the movable box body 1, and then the cover plate is engaged with the upper end of the movable box body 1. Through the above operation, it is convenient to store the high-voltage vacuum circuit breaker body 6 in the movable box body 1, which can play a certain protective role for the high-voltage vacuum circuit breaker body 6 when not in use, prevent the high-voltage vacuum circuit breaker body 6 from being eroded by external dust and water vapor, and extend the service life of the high-voltage vacuum circuit breaker body 6.
