[0025] like Figures 1 to 3 As shown, the portable lightning protection grounding resistance tester includes a protection box 1, a groove is provided on the lower surface of the protection box 1, a support mechanism 2 for driving the protection box 1 to move up and down is installed inside the groove of the protection box 1, the protection box 1 includes a resistance detector, a through hole is provided on the upper surface of the support mechanism 2, and a limit mechanism 5 for limiting the moving path of the protection box 1 is inserted inside the through hole of the support mechanism 2; specifically, the protection box 1 is pushed to move upward by adjusting the mobile support mechanism 2, so that the distance between the lower surface of the protection box 1 and the ground can be adjusted, thereby effectively keeping the grounding resistance detector inside the protection box 1 dry, thereby avoiding damage to the grounding resistance detector due to moisture during storage.

[0026] like Figure 1 and Figure 2As shown, the support mechanism 2 includes a diamond-shaped support plate 201, which is installed on the top of the inner wall of the groove of the protection box 1, and a fixing plate 202 is provided on the lower surface of the diamond-shaped support plate 201. The upper surface of the fixing plate 202 is attached to the lower surface of the protection box 1, and a groove is opened on the upper surface of the fixing plate 202. The inner walls on the left and right sides of the groove of the fixing plate 202 are provided with through holes, and the two groups of through holes of the fixing plate 202 are rotatably connected with screws 203, and the left and right sides of the screw 203 are provided with hexagonal grooves 204. The external threads of the screw 203 are connected with two groups of inclined plates 205, and the two groups of inclined plates 205 are slidably connected to the inside of the groove of the fixing plate 202, and the upper surfaces of the two groups of inclined plates 205 are respectively abutted against the left and right sides of the lower end of the diamond-shaped support plate 201;

[0027] Specifically, by pushing a group of hexagonal wrenches, the hexagonal wrenches are inserted into the inside of the hexagonal groove 204, and then the hexagonal wrenches are pushed to drive the screw 203 to rotate and drive the two groups of inclined plates 205 to drive the left and right sides of the lower end of the diamond support plate 201 to bend toward the central axis area of ​​the diamond support plate 201, so that the top of the diamond support plate 201 pushes the protection box 1 to move upward, and then the distance between the lower surface of the protection box 1 and the ground can be adjusted, so that the ground resistance detector inside the protection box 1 can be effectively kept dry, thereby minimizing damage to the ground resistance detector due to moisture during storage and storage; the fixing plate 202 can be folded and stored into the inside of the groove of the protection box 1 during use, so that the area occupied by the support mechanism 2 during idleness is reduced, thereby minimizing the subsequent support mechanism 2 affecting the normal carrying of the mobile protection box 1 by the staff, thereby improving the practicality of the device.

[0028] like Figures 1 to 3 As shown, the lower surface of the protective box 1 is provided with a U-shaped card slot, and a U-shaped sealing plate 3 is slidably connected inside the U-shaped card slot of the protective box 1, and the inner wall of the U-shaped sealing plate 3 is attached to the outer surface of the fixed plate 202; specifically, when the upper surface of the fixed plate 202 abuts against the lower surface of the protective box 1, the U-shaped sealing plate 3 is pulled to make the inner wall of the U-shaped sealing plate 3 attached to the outer surface of the fixed plate 202, so that the U-shaped sealing plate 3 blocks the connection between the fixed plate 202 and the lower surface of the protective box 1, thereby minimizing the risk of leakage. This can prevent dust from drifting along the fixed plate 202 and the protective box 1 to the inside of the groove of the protective box 1 during the subsequent idleness of the device, thereby reducing the number of times that the subsequent staff regularly cleans the equipment inside the groove of the protective box 1; the fixed plate 202 is clamped inside the U-shaped sealing plate 3, so that the U-shaped sealing plate 3 limits the moving position of the fixed plate 202 at the lower end of the protective box 1, thereby minimizing the movement of the fixed plate 202 during the impact and causing some equipment inside the support mechanism 2 to bend.

[0029] like Figure 3 As shown, a slot is provided on the lower surface of the U-shaped sealing plate 3, and a magnetic block 4 is installed inside the slot of the U-shaped sealing plate 3, and the upper surface height of the magnetic block 4 is kept parallel to the upper surface height of the U-shaped sealing plate 3; specifically, when the staff is adjusting the movable protection box 1, by pulling the U-shaped sealing plate 3, the upper surface of the magnetic block 4 is adsorbed on the top of the inner wall of the U-shaped slot of the protection box 1, so that the magnetic block 4 limits the moving position of the U-shaped sealing plate 3 inside the U-shaped slot of the protection box 1, so that the subsequent staff does not need to manually support the U-shaped sealing plate 3 during the process of turning the hex wrench, thereby reducing the labor consumed by the subsequent staff in operating the supporting mechanism 2 to adjust the height of the protection box 1.

[0030] like Figures 1 to 3 As shown, the limiting mechanism 5 includes a fixing rod 501, a card slot is provided on the upper surface of the fixing plate 202, the fixing rod 501 is inserted into the card slot of the fixing plate 202, a groove is provided on the upper surface of the fixing rod 501, a hydraulic cylinder 502 is installed inside the groove of the fixing rod 501, and an insertion rod 503 is installed at the output end of the hydraulic cylinder 502, and a through hole is provided on the inner top of the protective box 1, and the position of the through hole inside the protective box 1 is located on the moving path of the insertion rod 503; specifically, when the supporting mechanism 2 adjusts and supports the height of the protective box 1, the fixing rod 501 is pushed to insert the fixing rod 501 into the card slot of the fixing plate 202, and then the insertion rod 503 is pushed to move by starting the hydraulic cylinder 502, and the top of the insertion rod 503 is inserted into the through hole of the protective box 1, so that the limiting mechanism 5 limits the distance between the top of the inner wall of the groove of the protective box 1 and the upper surface of the fixing plate 202, thereby trying to avoid the internal equipment of the supporting mechanism 2 from being squeezed and bent when the protective box 1 is pressed later.

[0031] like Figure 1 and Figure 2 As shown, a positioning groove is provided on the upper surface of the fixed plate 202, and a side plate 6 is provided on the left side of the fixed rod 501, and the outer contour of the side plate 6 is adapted to the inner contour of the positioning groove of the fixed plate 202; specifically, when the limiting mechanism 5 is idle, the fixing rod 501 is disassembled and moved, and the side plate 6 is clamped in the positioning groove of the fixed plate 202, so that the internal positioning groove of the fixed plate 202 can store and accommodate the limiting mechanism 5, so that the staff can take it out in time when the device is used in the subsequent process of using the limiting mechanism 5; by adapting the outer contour of the side plate 6 to the inner contour of the positioning groove of the fixed plate 202, the inner contour of the positioning groove of the fixed plate 202 during the subsequent transportation and movement of the protective box 1 can limit the position of the side plate 6 and the limiting mechanism 5, so as to avoid the limiting mechanism 5 from swinging back and forth at the upper end of the fixed plate 202 during the subsequent transportation and movement of the protective box 1.

[0032] In summary: by pushing a set of hexagonal wrenches, the hexagonal wrenches are inserted into the inside of the hexagonal groove 204, and then the hexagonal wrenches are pushed to drive the screw 203 to rotate and push the two sets of inclined plates 205 to drive the left and right sides of the lower end of the diamond support plate 201 to bend toward the central axis area of ​​the diamond support plate 201, so that the top of the diamond support plate 201 pushes the protective box 1 to move upward, and then the distance between the lower surface of the protective box 1 and the ground can be adjusted, so that the ground resistance detector inside the protective box 1 can be effectively kept dry; by pulling the U-shaped sealing plate 3, the inner wall of the U-shaped sealing plate 3 is attached to the outer surface of the fixed plate 202, so that the U-shaped sealing plate 3 blocks the connection between the fixed plate 202 and the lower surface of the protective box 1, so as to avoid dust from floating along the fixed plate 202 and the protective box 1 to the inside of the groove of the protective box 1 during the subsequent idle process of the device.

[0033] At the same time, by pulling the U-shaped sealing plate 3, the upper surface of the magnetic block 4 is adsorbed on the top of the inner wall of the U-shaped slot of the protective box 1, so that the magnetic block 4 limits the moving position of the U-shaped sealing plate 3 inside the U-shaped slot of the protective box 1, so that subsequent staff do not need to manually support the U-shaped sealing plate 3 during the process of turning the hexagonal wrench; by pushing the fixing rod 501, the fixing rod 501 is inserted into the slot of the fixing plate 202, and then the insertion rod 503 is pushed to move by starting the hydraulic cylinder 502, and the top of the insertion rod 503 is inserted into the through hole of the protective box 1, so that the limiting mechanism 5 limits the distance between the top of the inner wall of the groove of the protective box 1 and the upper surface of the fixing plate 202, so as to avoid the internal equipment of the supporting mechanism 2 from being squeezed and bent when the protective box 1 is pressed later.
