[0025] The working principle and usage process of the present invention: First, since the front surface of the box body 1 is hinged with a box cover 11 through a hinge, the box cover 11 can be opened to operate the inside of the box body 1, and it is convenient to open the box cover 11 through the handle 12. It is convenient to place and move the device through the two support legs 13 at the bottom of the box body 1, the two support frames 14, and the rollers 15. Through the provided storage mechanism 2, the detection device body 21 in the storage mechanism 2 is installed on the partition plate 16 inside the box body 1. The partition plate 16 facilitates dividing the box body 1 into two layers. The wires electrically connected to the input end of the detection device body 21 penetrate down between the back surface of the partition plate 16 and the side of the back surface of the box body 1 that are close to each other, and pass through the winding assembly 22. The support plate 221 in the winding assembly 22 is fixed to the inner wall of the bottom of the box body 1. The support plate 221 can support the support rod 222. One side of the outer wall of the support rod 222 away from the support plate 221 is rotationally connected to a circular rotating plate 223 through a bearing. The connected wires penetrate out from the guide tube 224, and then the wires can be wound around the outer wall of the support rod 222 by rotating the circular rotating plate 223. The transmission component 26 in the storage mechanism 2 is arranged outside the first rotating rod 23, and the outer wall of the first rotating rod 23 is slidably connected to both sides of the box body 1. The first rotating rod 23 can be driven to rotate by the hand-cranked turntable 24. Since the fixed sleeve 261 is fixedly sleeved on the outer wall of the first rotating rod 23, the first rotating rod 23 can drive the rotation of the fixed sleeve 261. One side of the fixed sleeve 261 is fixedly connected with an annular magnet 263, and the annular magnet 263 can adsorb the iron ring 264. At the same time, a limiting strip 262 is fixedly connected to the same side of the fixed sleeve 261 and the annular magnet 263. The iron ring 264 is also sleeved on the outer wall of the first rotating rod 23. When the circular rotating plate 223 needs to rotate, the first rotating rod 23 is lifted upward, and the limiting groove 266 is slid into the outer wall of the limiting strip 262 and fixed under the adsorption action. By releasing the first rotating rod 23, the outer wall of the rubber sleeve 265 can be attached to the outer wall of the circular rotating plate 223 under the action of gravity. Then, when the first rotating rod 23 is rotated, the rubber sleeve 265 can drive the circular rotating plate 223 to rotate under the action of friction, facilitating the winding of the wire around the outer wall of the support rod 222. And when one of the wires is wound up and the others are not, the first rotating rod 23 is lifted upward, and the corresponding iron ring 264 is moved away from the annular magnet 263; Through the pressing component 25 in the storage mechanism 2, the pressing plate 254 can be limited by the limiting sliding of the outer wall of the limiting rod 251 in the inner wall of the tension spring 253. The pressing plate 254 can be pressed downward by the tension spring 253 under the tension. The first fixing block 255 fixedly connected to the bottom of the pressing plate 254 is rotatably connected to the outer wall of the first rotating rod 23 through a bearing, which does not affect the rotation of the first rotating rod 23 and can give a certain pressing force to the first rotating rod 23, facilitating the rubber sleeve 265 to better increase the friction with the circular rotating plate 223; Through the provided limiting mechanism 3, the support block 31 in the limiting mechanism 3 is fixed to support the two insertion rods 32. The top of the insertion rod 32 is fixedly connected with a connecting iron plate 33, and a pressing rod 34 is fixedly connected to the connecting iron plate 33, facilitating the pressing rod 34 to drive the connecting iron plate 33 to move downward and insert into the ground soil, effectively realizing the fixation of the box body 1. When the box body 1 needs to be moved, the connecting iron plate 33 is adsorbed by the iron suction block 35 fixedly connected to the bottom of the second fixing block 36, and the box body 1 is tilted by pulling the pull rod 37. Therefore, the two rollers 15 can move on the ground; Through the provided pulling mechanism 4, which is fixed to the lower surface of the partition plate 16 by the fixed box 41 in the pulling mechanism 4, the internal parts can be supported. When the first rotating rod 23 needs to move upward, by rotating the knob 43, and the knob 43 can drive the rotation of the second rotating rod 42. Through the second rotating rod 42, the rotation of the gear 44 can be driven. Since the gear 44 meshes with the rack 46, the rack 46 can be realized to move upward on the inner wall of the fixed box 41, and the rack 46 can pull the first rotating rod 23 through the sleeve block 45, thus facilitating use. At the same time, when the first rotating rod 23 does not need to move upward, it can be achieved by loosening the knob 43.

10. A detection device and operation method for detecting the service life of a power grounding grid, characterized in that: Applied to the detection device for detecting the service life of the power grounding grid according to any one of claims 1 to 9, the steps are as follows: Since the front of the box body (1) is hinged with a box cover (11) through a hinge, the box cover (11) can be opened to operate the inside of the box body (1), and it is convenient to open the box cover (11) through the pull handle (12). The two support legs (13) at the bottom of the box body (1), the two support frames (14), and the rollers (15) facilitate the placement and movement of the device; Through the provided storage mechanism (2), the detection device body (21) in the storage mechanism (2) is installed on the partition plate (16) inside the box body (1). The partition plate (16) facilitates dividing the box body (1) into two layers. The wires electrically connected to the input end of the detection device body (21) penetrate down between the back of the partition plate (16) and the side of the box body (1) close to the back, and pass through the winding assembly (22). The support plate (221) in the winding assembly (22) is fixed to the inner wall of the bottom of the box body (1). The support plate (221) can support the support rod (222). One side of the outer wall of the support rod (222) away from the support plate (221) is connected by a bearing to a circular rotating plate (223). The connected wires penetrate out through the guide pipe (224). Then, by rotating the circular rotating plate (223), the wires can be wound around the outer wall of the support rod (222); The transmission component (26) in the storage mechanism (2) is arranged outside the first rotating rod (23), and the outer wall of the first rotating rod (23) is slidably connected to both sides of the box body (1). The first rotating rod (23) can be driven to rotate by the hand-cranked turntable (24). Since the fixed sleeve (261) is fixedly sleeved on the outer wall of the first rotating rod (23), the first rotating rod (23) can drive the fixed sleeve (261) to rotate. One side of the fixed sleeve (261) is fixedly connected with an annular magnet (263), and the annular magnet (263) can adsorb the iron ring (264). At the same time, a limiting strip (262) is fixedly connected to the same side of the fixed sleeve (261) and the annular magnet (263). The iron ring (264) is also sleeved on the outer wall of the first rotating rod (23). When the circular rotating plate (223) needs to rotate, the first rotating rod (23) is lifted upward, and the limiting groove (266) is slid into the outer wall of the limiting strip (262) and fixed under the adsorption action. By releasing the first rotating rod (23), the outer wall of the rubber sleeve (265) can be attached to the outer wall of the circular rotating plate (223) under the action of gravity. Then, when the first rotating rod (23) is rotated, the rubber sleeve (265) can drive the circular rotating plate (223) to rotate under the action of friction, facilitating the winding of the wire around the outer wall of the support rod (222). And when one wire is wound up and the others are not, the first rotating rod (23) is lifted upward, and the corresponding iron ring (264) is moved away from the annular magnet (263); Through the pressing component (25) in the storage mechanism (2), the pressing plate (254) can be limited by the limiting sliding of the outer wall of the limiting rod (251) in the inner wall of the tension spring (253). The pressing plate (254) can be pressed downward by the tension spring (253) under the tension action. The first fixed block (255) fixedly connected to the bottom of the pressing plate (254) rotates with the outer wall of the first rotating rod (23) through a bearing, which does not affect the rotation of the first rotating rod (23), and at the same time can apply a certain pressing force to the first rotating rod (23), facilitating the rubber sleeve (265) to better increase the friction with the circular rotating plate (223); Through the provided limit mechanism (3), the support block (31) in the limit mechanism (3) can fix and support the two insertion rods (32). A connecting iron plate (33) is fixedly connected to the top of the insertion rod (32), and a pressing rod (34) is fixedly connected to the connecting iron plate (33). Thus, it is convenient for the pressing rod (34) to drive the connecting iron plate (33) to move downward and insert into the ground soil, effectively realizing the fixation of the box body (1). When the box body (1) needs to be moved, the connecting iron plate (33) is adsorbed by the magnet block (35) fixedly connected to the bottom of the second fixing block (36), and the box body (1) is tilted by pulling the pull rod (37). Therefore, the box body can move on the ground through the two rollers (15). Through the provided pulling mechanism (4), the fixed box (41) in the pulling mechanism (4) is fixed on the lower surface of the partition plate (16), so it can support the internal parts. When the first rotating rod (23) needs to move upward, the knob (43) is rotated, and the knob (43) can drive the rotation of the second rotating rod (42). The second rotating rod (42) can drive the rotation of the gear (44). Since the gear (44) meshes with the rack (46), the rack (46) can move upward on the inner wall of the fixed box (41), and the rack (46) can pull the first rotating rod (23) through the sleeve block (45), which is convenient for use. At the same time, when the first rotating rod (23) does not need to move upward, the knob (43) is loosened.
