[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: an adjustable electric field optimization shield, including a base 1, a first shield box 2 fixedly connected to the top of the base 1, a second shield box 3 slidably connected to the top of the base 1, a high-voltage transmission body 4 fixedly connected to the top of the base 1, and a positioning component 5 and a sealing component 6 fixedly connected to the outer wall of the first shield box 2; the positioning component 5 includes a support column 51, a rotating rod 52 rotatably connected to the top of the support column 51, a limit sleeve 53 rotatably connected to the outer wall of the rotating rod 52, a connecting rod 54 fixedly connected to the outer wall of the rotating rod 52, a sleeve post 55 fixedly connected to the outer wall of the connecting rod 54, a positioning post 56 slidably connected to the inner wall of the sleeve post 55, a limit block 57 fixedly connected to the outer wall of the positioning post 56, a pull ring 58 fixedly connected to the top of the positioning post 56, and a first elastic ring sleeved on the outer wall of the positioning post 56. Spring 59 and support column 51 are fixedly connected to the top of the first cover box 2. Limiting sleeve 53 is fixedly connected to the top of the first cover box 2. The bottom of positioning column 56 is provided with a circular locking block. Positioning column 56 contacts the second cover box 3 through the circular locking block at the bottom. The first cover box 2 restricts the movement of support column 51 and the fixed sleeve. The fixed sleeve can prevent rotating column 65 from shaking and deviating. Positioning column 56 contacts the second cover box 3 through the elastic force applied by the first spring 59 and its bottom circular locking block, so that the first cover box 2 and the second cover box 3 are initially positioned. One end of the first spring 59 is fixedly connected to the bottom of sleeve column 55, and the other end of the first spring 59 is fixedly connected to the circular locking block at the bottom of positioning column 56. The first spring 59 can make positioning column 56 slide up and down on the inner wall of the cover box through the elastic force.

[0024] The sealing assembly 6 includes a fixed plate 61, a sliding column 62 fixedly connected to the inner wall of the fixed plate 61, a second spring 63 sleeved on the outer wall of the sliding column 62, a slider 64 slidably connected to the outer wall of the sliding column 62, a rotating column 65 rotatably connected to the inner wall of the slider 64, a rotating plate 66 fixedly connected to the outer wall of the rotating column 65, an insert block 67 fixedly connected to the outer wall of the rotating plate 66, a locking block 68 fixedly connected to the outer wall of the second cover box 3, a slot 69 formed in the wall of the locking block 68, the outer wall of the fixed plate 61 fixedly connected to the outer wall of the first cover box 2, one end of the second spring 63 fixedly connected to the outer wall of the slider 64, and the other end of the second spring 63 fixedly connected to the outer wall of the fixed plate 61. The first cover box 2 restricts the position of the fixed plate 61, and the second spring... One end of the spring 63 is fixed to the outer wall of the fixed plate 61, and the other end is fixedly connected to the slider 64. In the initial state, the second spring 63 uses its elastic force to make the slider 64 fit against the fixed plate 61. The locking block 68 is fixedly connected to the outer wall of the second cover box 3 by bolts. The insert block 67 is inserted into the slot 69. The outer wall of the slider 64 is in contact with the outer wall of the fixed plate 61. The insert block 67 is fixedly connected to the outer wall of the rotating plate 66. The slider 64 drives the rotating plate 66 to move. After the insert block 67 is inserted into the slot 69, the spring will apply a force away from the locking block 68, so that the first cover box 2 and the second cover box 3 fit more tightly. The bolts fix the locking block 68 to make it more stable. The slider 64 is made to fit against the fixed plate 61 by the force applied by the second spring 63.

[0025] When shielding the high-voltage transmission body 4 is required, since the first cover 2 is fixedly connected to the base 1, the second cover 3 is moved by rollers at its bottom to connect the first cover 2 and the second cover 3. Initial positioning is achieved using the positioning component 5. At this time, pulling the pull ring 58 causes the positioning post 56 to move upwards against the elastic force of the first spring 59, causing the circular locking block at the bottom of the positioning post 56 to disengage from its initial position. After sliding the second cover 3 to the position corresponding to the first cover 2, the pull ring 58 is released. The first spring 59 recovers its deformation due to its own elasticity, pushing the positioning post 56 downwards. The circular locking block at the bottom of the positioning post 56 contacts and engages with the second cover 3, thus achieving initial positioning when the first cover 2 and the second cover 3 are connected. This restricts the relative movement between the two, providing a stable foundation for the subsequent operation of the sealing component 6. After initial positioning, the sealing component 6 is operated to further strengthen the connection and achieve a sealing effect. In the initial state, under the elastic force of the second spring 63, the slider 64... The insert 67 on the rotating plate 66 is positioned away from the slot 69 of the locking block 68, and is tightly fitted to the fixed plate 61. When the slider 64 is pushed, it slides on the sliding column 62. The slider 64 drives the rotating column 65 and the rotating plate 66 to move. The rotating plate 66 drives the insert 67 to move towards the slot 69 of the locking block 68. When the insert 67 is inserted into the slot 69 of the locking block 68, the second spring 63 applies a force away from the locking block 68, pushing the slider 64 to firmly lock the insert 67 in the slot 69. This makes the first cover 2 and the second cover 3 fit more tightly, which not only enhances the connection but also prevents external factors from affecting the electric field environment inside the shielding cover, achieving a good sealing effect. During the entire operation, the base 1 provides stable support for the shielding cover. The high-voltage transmission body 4 is placed inside the shielding cover. The first cover 2 and the second cover 3 are tightly connected by the positioning component 5 and the sealing component 6 to form a complete shielding space, optimize the electric field distribution, reduce electric field interference, and ensure the stable and safe operation of the high-voltage transmission body 4.
