The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for specific purposes.

[0017] Example: See Figure 1 - Figure 5 The utility model provides a technical solution: a power supply control device for an MVB online monitoring device, comprising: a power supply control body 1; a mounting device 2, the outer wall of the mounting device 2 is fixedly connected to the outer wall of the power supply control body 1; a protection device 4, the outer wall of the protection device 4 is fixedly connected to the outer wall of the mounting device 2; the mounting device 2 comprises a fixing frame 21, the outer wall of the fixing frame 21 is slidably connected to a U-shaped sliding plate 22, the outer wall of the U-shaped sliding plate 22 is fixedly connected to a damping rod 24, and fixing plates 23 are arranged on both sides of the U-shaped sliding plate 22, and the outer wall of the fixing plate 23 is fixedly connected to the outer wall of the fixing plate 23. A connecting shaft 25 is fixedly connected, and a compression spring 26 is sleeved on the outer wall of the connecting shaft 25. The outer wall of the fixed frame 21 is symmetrically fixedly connected with a reinforcement frame 3. The outer wall of the U-shaped sliding plate 22 is fixedly connected to the outer wall of the power control body 1. The fixed frame 21 is pre-fixed as a basic supporting component. The U-shaped sliding plate 22 can slide along the fixed frame 21 with the power control body 1 connected thereto. This is due to the sliding connection design of the two. When the equipment is impacted by external force, such as accidental collision or transportation bumps, the U-shaped sliding plate 22 will move, and at this time the damping rod 24 has a buffering effect.

[0018] The outer wall of the fixing frame 21 is fixedly connected to one end of the damping rod 24 away from the U-shaped sliding plate 22, one end of the compression spring 26 is fixedly connected to the outer wall of the U-shaped sliding plate 22, the other end of the compression spring 26 is fixedly connected to the outer wall of the fixing plate 23, the outer wall of the fixing plate 23 is fixedly connected to the outer wall of the fixing frame 21, and the end of the connecting shaft 25 away from the fixing plate 23 is fixedly connected to the outer wall of the fixing frame 21. The compression springs 26 on both sides are compressed or stretched by force to absorb impact energy. One end of them is connected to the U-shaped sliding plate 22, and the other end is connected to the fixing plate 23. The connecting shaft 25 ensures that the compression springs 26 can stably expand and contract. After the impact force disappears, the compression springs 26 will rebound and push the U-shaped sliding plate 22 to reset, so that the power control body 1 returns to its initial position, and the reinforcement frame 3 enhances the stability of the fixing frame 21, thereby protecting the power control body 1 from damage.

[0019] The protective device 4 includes a sliding frame 41, the inner wall of the sliding frame 41 is fixedly connected to a connecting block 43 through a mounting groove 42, and the mounting groove 42 is provided in the wall of the sliding frame 41, the outer wall of the connecting block 43 is fixedly connected to an elastic plate 44, and the outer wall of the elastic plate 44 is provided with a connecting groove 45, the outer wall of the sliding frame 41 and the outer wall of the connecting block 43 are both slidably connected to the outer wall of the reinforcement frame 3, the outer wall of the elastic plate 44 is fixedly connected to the outer wall of the fixed plate 23 through the connecting groove 45, the sliding frame 41 slides along the reinforcement frame 3, the sliding frame 41 moves synchronously with the connecting block 43 fixed by the mounting groove 42, and at this time the elastic plate 44 on the connecting block 43 moves synchronously, because the elastic plate 44 has a certain flexibility, when encountering external force, the elastic plate 44 can buffer energy through its own deformation, and the connecting groove 45 is connected to the fixed plate 23 to further stabilize the structure.

[0020] Working principle:

[0021] When in use, the mounting device 2 first takes effect, the fixing frame 21 is fixed in advance as a basic support component, and the U-shaped sliding plate 22 with the power control body 1 connected thereto can slide along the fixing frame 21, thanks to the sliding connection design of the two. When the device is impacted by external force, such as an accidental collision or transportation bumps, the U-shaped sliding plate 22 will move, and at this time the damping rod 24 plays a buffering effect, which can control the sliding speed of the U-shaped sliding plate 22 to prevent it from shaking violently due to excessive impact force;

[0022] At the same time, the compression springs 26 on both sides are compressed or stretched by force to absorb the impact energy. One end of them is connected to the U-shaped sliding plate 22, and the other end is connected to the fixed plate 23. The connecting shaft 25 ensures that the compression spring 26 is stably extended and retracted. After the impact force disappears, the compression spring 26 will rebound and push the U-shaped sliding plate 22 to reset, so that the power control body 1 returns to the initial position. The reinforcement frame 3 enhances the stability of the fixed frame 21, thereby protecting the power control body 1 from damage and ensuring the stable operation of the equipment.

[0023] The protection device 4 also cooperates in protection. The sliding frame 41 slides along the reinforcement frame 3. The sliding frame 41 moves synchronously with the connecting block 43 fixed by the installation groove 42. At this time, the elastic plate 44 on the connecting block 43 moves synchronously. Since the elastic plate 44 has a certain flexibility, when encountering external force, the elastic plate 44 can buffer energy through its own deformation. The connecting groove 45 is connected to the fixed plate 23 to further stabilize the structure and prevent external impact from directly acting on the power control body 1, thereby reducing the risk of equipment failure, extending the service life, and maintaining the continuous and stable use of the MVB online monitoring equipment.

[0024] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
