[0005] The technical solution of this utility model is: a portable isolation device for mobile electrical equipment in mines, comprising a support frame, a movable frame, a folding frame, a pin, a slider, a limiting frame, a first telescopic spring, a shielding component, and a locking component. Multiple support frames are provided, with movable frames rotatably connected to the left and right sides of each support frame. Sliding sliders are slidably connected to the upper and lower parts of each movable frame. Multiple folding frames are provided, each folding frame rotatably connected to its adjacent slider. A pin is engaged between the movable frame on the right front side and the slider above it. A limiting frame is slidably connected to the lower left side of each support frame, and each limiting frame is engaged with an adjacent movable frame. A first telescopic spring connects each limiting frame to an adjacent support frame. The support frame is provided with a shielding component that allows for easy expansion and contraction, and the shielding component is provided with a locking component that allows for limiting and locking.
[0006] Furthermore, the lower side of the mobile frame is equipped with rotatable casters.
[0007] Furthermore, the restraint frame has a T-shaped structure.

Detailed Implementation
[0019] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0020] A portable isolation device for mobile electrical equipment in mines, such as Figures 1-4 As shown, the system includes a support frame 1, a movable frame 2, a folding frame 3, a pin 31, a slider 4, a limiting frame 5, a first telescopic spring 6, a blocking component, and a locking component. There are three support frames 1. The left and right sides of each support frame 1 are rotatably connected to a movable frame 2. Each movable frame 2 has rotatably mounted wheels on its lower side for easy movement. The upper and lower parts of each movable frame 2 are slidably connected to sliders 4. There are four folding frames 3. Each folding frame 3 is rotatably connected to its adjacent slider 4. A pin 31 is locked between the right front movable frame 2 and its upper slider 4. Each support frame 1 has a sliding limiting frame 5 on its lower left side. The limiting frame 5 has a T-shaped structure for easy gripping and maneuvering. Each limiting frame 5 is locked to its adjacent movable frame 2. Each limiting frame 5 is connected to its adjacent support frame 1 by a first telescopic spring 6. The support frame 1 has a blocking component, and the blocking component has a locking component.
[0021] like Figure 1 and Figure 5 As shown, the shielding assembly includes a first winding rod 7, a second winding rod 71, a third winding rod 72, a spring 8, a shielding cloth 9, and a pull rope 10. The first winding rod 7 is rotatably connected to the support frame 1 at the frontmost and rearmost sides, and the second winding rod 71 is rotatably connected to the movable frame 2 at the frontmost and rearmost sides. The third winding rod 72 is also rotatably connected to the upper part of the support frame 1 at the frontmost and rearmost sides. The shielding cloth 9 is wound around the first winding rod 7 and the second winding rod 71 near the rear, and the shielding cloth 9 is also wound around the third winding rod 72. Two spring springs 8 are connected between each shielding cloth 9 and its adjacent first winding rod 7, second winding rod 71, and third winding rod 72. Two pull ropes 10 are connected to each shielding cloth 9, and the pull ropes 10 are connected to their adjacent first winding rod 7 and second winding rod 71.
[0022] like Figure 6As shown, the locking assembly includes a limiting rod 11, a second telescopic spring 12, and a pull ring 13. The front and rear shielding cloths 9 are slidably connected to the limiting rod 11. The limiting rod 11 is locked to its adjacent movable frame 2. The second telescopic spring 12 is connected between the limiting rod 11 and the adjacent shielding cloth 9. The side of the limiting rod 11 that is far away from each other is connected to the pull ring 13.
[0023] When using this device, first move the support frame 1 next to the mobile electrical equipment in the mine to be isolated, then move the limiting frame 5 upwards, the first telescopic spring 6 retracts, then rotate and unfold the moving frame 2, then release the limiting frame 5, the first telescopic spring 6 returns to its original position, causing the limiting frame 5 to move downwards and lock with the moving frame 2, thus locking the moving frame 2 in place. Next, unfold the moving frame 2, causing the folding frame 3 to rotate and unfold, while simultaneously sliding on the moving frame 2 to move it. Unfold the support frame 1 and the moving frame 2, then insert the pin 31 between the slider 4 and the moving frame 2 to lock them in place. As the support frame 1 and the moving frame 2 unfold, the first winding rod 7 and the second... The winding rod 71 rotates, and the pull rope 10 pulls the upper and left and right side shielding cloths 9 to unfold. The spring 8 deforms, and then the front and rear shielding cloths 9 are pulled down to unfold, driving the third winding rod 72 to rotate. Then the pull ring 13 is pulled outward, driving the limiting rod 11 to move. The second telescopic spring 12 is stretched. After the shielding cloths 9 are pulled to the designated position, the pull ring 13 is released, the second telescopic spring 12 returns to its original state, and the limiting rod 11 moves to engage with the moving frame 2, locking the shielding cloths 9 on the front and rear sides. This allows the mine's mobile electrical equipment to be placed between the shielding cloths 9 for shielding and isolation, completing the overall unfolding of the isolation device and the isolation operation.
[0024] When the device needs to be folded up, pulling the pull ring 13 moves the limiting rod 11 to release its engagement with the moving frame 2, stretching the second telescopic spring 12. At this time, the spring 8 on the third winding rod 72 returns to its original position, causing the third winding rod 72 to rotate in the opposite direction, rewinding the front and rear cover cloths 9. Then, the pin 31 is pulled out, and the moving frame 2 is pushed to fold together. The slider 4 moves with the moving frame 2, causing the folding frame 3 to fold and fold together. At the same time, the remaining spring 8 returns to its original position, rewinding the remaining cover cloths 9. Then, the limiting frame 5 is moved to release its lock with the moving frame 2, and the moving frame 2 is rotated upwards to fold together, completing the overall folding up of the device. This allows for easy folding and unfolding, making it convenient to carry and store, and reducing the floor space occupied.
[0025] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
