The charging head clamping mechanism 2 comprises a second electric cylinder 201 fixed on the sliding plate 113, a main support 202 is fixedly connected with an expansion rod of the second electric cylinder 201, two horizontal sliding rods 203 are connected on the main support 202 in a sliding manner, a third spring 204 is sleeved on each horizontal sliding rod 203, a clamping plate 205 is fixed at the end part of each horizontal sliding rod 203, an L-shaped sliding rod 206 is further fixed on the main support 202, an L-shaped sliding plate 207 is fixed on each horizontal sliding rod 203, and a strip-shaped groove matched with the width of the L-shaped sliding rod 206 is formed in the middle part of each L-shaped sliding plate 207; a sliding groove seat 208 and a rotating shaft seat 209 are fixed at the horizontal part of the L-shaped sliding plate 207, a horizontal rack 210 is arranged in the sliding groove seat 208 in a sliding manner, the horizontal rack 210 is connected with the L-shaped sliding rod 206 through a fourth spring 211, a coaxial pinion 212 and a bull gear 213 are arranged on the rotating shaft seat 209 in a rotating manner, a vertical clamping strip 214 is also arranged at the horizontal part of the L-shaped sliding plate 207 in a sliding manner, a wedge-shaped surface is arranged at the lower part of the clamping strip 214, and a vertical rack 215 is fixed at the back side; the vertical rack 215 is engaged with the large gear 213, and the horizontal rack 210 is engaged with the small gear 212.
The second electric cylinder 201 is a bidirectional electric cylinder, when the charging head T to be tested is inserted into the testing connector 104, the second electric cylinder 201 drives the main brackets 202 at the two sides of the charging head T to approach, when the clamping plate 205 contacts the charging head T, the third spring 204 starts to be compressed, and simultaneously the two horizontal sliding rods 203 slide out of the main bracket 202 (vertical plate on the main bracket 202), thereby moving the L-shaped sliding plate 207 in a direction away from the charging head T along the horizontal portion of the L-shaped sliding rod 206, due to the action of the horizontal rack 210, the pinion 212 starts to rotate, and further drives the coaxial bull gear 213 to rotate synchronously, the bull gear 213 drives the vertical rack 215 to move downwards, that is, drives the clamping bar 214 to move downwards, so that the wedge shape of the clamping bar 214 presses the clamping plate 205 toward the charging head T, which is equivalent to forcibly inserting the wedge behind the clamping plate 205, thereby clamping the charging head T very firmly.

After the sand raising environment is simulated, the rain weather is tested, the water in the water tank 301 is pumped out by the water pump 302 and is sprayed down by the spray header 303, the rain environment is simulated, and after a period of time, the valve 304 is opened, and the water is pumped out by the water pump 302. The simulated rain environment is placed after the simulated sand raising environment, and dust pollution caused by sand raising experiments can be cleaned. When the rain environment is simulated, the fan 110 can be started at the same time, so that the simulated environment is more in line with diversity.
The testing device is also internally provided with a cable centering mechanism 4, the cable centering mechanism 4 consists of an upper part and a lower part which are symmetrical with each other, the lower part comprises a narrow plate 401 and an L-shaped wide plate 402 which are symmetrically fixed on the inner side wall of the lower half sealed box 108, a sliding column 403 is vertically arranged on the narrow plate 401 in a sliding manner, a first spring 404 is sleeved on the sliding column 403, and a V-shaped plate 405 is fixed on the two sliding columns 403; a sliding rod 406 is arranged at the vertical section of the L-shaped wide plate 402 in a sliding manner, a second spring 407 is sleeved on the sliding rod 406, a triangular frame 408 is fixed at the end part of the sliding rod 406, the triangular frame 408 is arranged on the horizontal section of the L-shaped wide plate 402 in a sliding manner, and meanwhile, the width of the narrow plate 401 is smaller than that of the triangular frame 408; a Z-shaped rod 409 is further fixed on one side of the narrow plate 401, the whole Z-shaped rod 409 is parallel to the sliding column 403, and the end part of the Z-shaped rod 409 is positioned right below the inclined plane of the triangular frame 408 on the upper half part of the cable centering mechanism 4; for the upper half, the structure and principle are the same as for the lower half, and the part corresponding to the V-shaped plate 405 is called an inverted V-shaped plate.
The Z-shaped rod 409 of the lower half is arranged at the following positions: when the upper and lower hermetic containers 107 and 108 are close to each other, the end of the Z-shaped rod 409 fixed to the lower hermetic container 108 can slide along the slope of the triangular frame 408 in the upper hermetic container 107, and when the upper and lower hermetic containers 107 and 108 are butted and sealed, the Z-shaped rod 409 can completely separate the triangular frame 408 from the slide post 403 (see side view of fig. 4).
Because the cable should pass between the upper semi-sealed box 107 and the lower semi-sealed box 108, and in order to realize a sealed environment, the two boxes are required to be completely and hermetically butted, the cable needs to be completely placed in the wire inlet groove on the box board without error, and the error often occurs in manual operation. Therefore, the cable centering mechanism 4 is designed, and centering can be automatically realized.
During testing, in the process that the upper half seal box 107 and the lower half seal box 108 approach each other, under the action of the second spring 407, the triangular frame 408 is pushed outward, so that the vertical surface of the triangular frame 408 and the sliding column 403 are at the same vertical position (see the state in fig. 13, the triangular frame 408 is located right below the sliding column 403), at this time, the first spring 404 is in a completely relaxed state and does not generate an elastic action, so that the V-shaped plate 405 connected with the sliding column 403 is rigidly fixed, and similarly, the inverted V-shaped plate above is also rigidly fixed, and when the V-shaped plate 405 and the inverted V-shaped plate are respectively contacted with the cable, no matter the position relation between the cable and the V-shaped plate 405 or the inverted V-shaped plate at this time, the V-shaped plate 405 and the inverted V-shaped plate are pushed to the central positions of the V-shaped plate 405 and the inverted V-shaped plate; then the upper and lower semi-sealed cases 107 and 108 are continuously close to each other, when the free end (i.e. the end not fixed with the case) of the Z-shaped rod 409 contacts the inclined surface of the triangular frame 408, the triangular frame 408 is pressed during sliding along the inclined surface, the triangular frame 408 is pushed inwards (pushed towards the center of the V-shaped plate 405 or the inverted V-shaped plate), and when the triangular frame 408 is completely separated from the sliding column 403, the first spring 404 is changed from a relaxed state to a compressed state, so that the V-shaped plate 405 and the inverted V-shaped plate respectively clamp the cable upwards and downwards simultaneously.
