[0043] A controller 13 is provided on the rainproof assembly 12 and is connected to the contact switch 7; the controller 13 controls the cooperation between the rainproof assembly 12 and the limiting plate 11 to prevent rainwater from entering the box body 1.

[0044] In this embodiment, the rain drop sensor 23 is connected to the controller 13. When the contact switch 7 is triggered by the movable cabinet door 4, the controller 13 controls the rain drop sensor 23 to turn on. When the rain drop sensor 23 detects that raindrops are falling, the controller 13 controls the driving motor 15 to start working, so that the rain shield 18 passes through the first avoidance groove 19 and cooperates with the limit plate 11 to prevent rainwater from entering the box body 1. The front end of the limit plate 11 is arc-shaped and fits with the inner surface of the rain shield 18. Two accommodation grooves 24 are provided at the rear end of the limit plate 11. Two limit posts 25 are also provided in the limit groove 8, and the limit posts 25 are slidably matched with the accommodation grooves 24 at the corresponding positions. Two springs 9 are provided in the limit groove 8 and are respectively sleeved on the limit posts 25 at the corresponding positions, so that when the movable cabinet door 4 moves downward along the sliding groove 6, the springs 9 can pop out the front end part of the limit plate 11 from the limit groove 8.

[0045] In addition, a plurality of cable grooves 26 are provided at the bottom of the access window 2. When the front end of the rain shield 18 abuts against the front end of the box body 1, the lower end of the cable groove 26 is not completely blocked by the front end of the rain shield 18, which is convenient for placing cables. A lock groove 27 that cooperates with the box body 1 is provided at one end of the movable cabinet door 4 close to the box body lock 10, which is convenient for fixing the movable cabinet door 4 in front of the access window 2. An avoidance groove four 28 is provided in the middle of one side of the sliding groove 6 close to the front end of the box body 1, and the slider 5 can slide out of the sliding groove 6 from the avoidance groove four 28, which is convenient for removing the movable cabinet door 4 for maintenance and replacement.

[0046] Working principle: When the rainproof device for the power generation vehicle access box of the present invention is connected and used with the power generation vehicle, it is necessary to open the box body lock 10 with a key to separate the box body lock 10 from the lock groove 27 on the movable cabinet door 4, and the sliders 5 at the upper ends of the inner sides of the two side plates of the movable cabinet door 4 move downward along the outer walls of the two side plates of the box body 1; when the movable cabinet door 4 moves downward along the chute 6, the limiting plates 11 in the limiting grooves 8 on the two side plates of the box body 1 pop out of the limiting grooves 8 under the action of the spring 9, and the front parts of the limiting plates 11 extend out of the limiting grooves 8; when the movable cabinet door 4 moves downward to contact the contact switch 7 at the lower end of the chute 6, the movable cabinet door 4 stops sliding down, and at this time the contact switch 7 is triggered, and the PLC controller 13 controls the rain drop sensor 23 at the top of the rain shield 18 to turn on; when the rain drop sensor 23 detects that raindrops are falling, it transmits a signal to the controller 13, and the controller 13 controls the driving motor 15 to start working; the output shaft of the driving motor 15 drives the transmission rods 16 at both ends thereof to rotate, and then drives the support plates 17 connected thereto to rotate; the two support plates 17 are connected to each other through a connecting plate 22, and the connecting plate 22 is welded and fixed to the rear end of the rain shield 18, so when the driving motor 15 works, it can drive the rain shield 18 to rotate. When the rain shield 18 rotates, its front end passes through the avoidance groove 19 at the front end of the top cover 14 and finally abuts against the front end of the box body 1, which can prevent rainwater from entering the access window 2 from the front end of the box body 1; when the rain shield 18 abuts against the front end of the box body 1, the driving motor 15 stops working, and at this time the inner surface of the rain shield 18 fits with the front end of the limiting plate 11, which can prevent rainwater from entering the access window 2 from the side of the box body 1, and can solve the problem that when the power generation vehicle access box is connected to the power generation vehicle and the movable cabinet door 4 is in the open state, rainwater may enter the interior of the power generation vehicle access box and damage the internal motors and components of the power generation vehicle access box.

[0047] When the rain stops, the driving motor 15 can be controlled to rotate in the reverse direction through the manual button on the controller 13, so that the rain shield 18 returns to the initial position; then the cable connected to the access box of the power generation vehicle is unplugged, and the movable cabinet door 4 is manually pushed upward along the chute 6 to make the movable cabinet door 4 return to the initial position, and is fixed at the front end of the access window 2 through the cabinet body lock 10. Since the front end of the limit plate 11 is arc-shaped, when the movable cabinet door 4 moves upward, the front end of the limit plate 11 contacts the inner side of the movable cabinet door 4, and the rear end of the limit plate 11 presses the spring 9 to compress the spring 9 on the limit post 25 until the front end of the limit plate 11 slowly retracts into the limit groove 8. It should be noted that a plurality of cable grooves 26 are opened at the bottom of the access window 2. When the front end of the rain shield 18 abuts against the front end of the cabinet body 1, the lower end of the cable groove 26 is not completely blocked by the front end of the rain shield 18, and the cable connecting the power generation vehicle and the power generation vehicle access box can be placed in the cable groove 26 to avoid being damaged by the front end of the rain shield 18. Avoidance grooves four 28 are provided in the middle of one side of the chute 6 on both side plates of the cabinet body 1 close to the front end of the cabinet body 1, and the slider 5 can slide out of the chute 6 from the avoidance grooves four 28, so as to facilitate the removal of the movable cabinet door 4 for maintenance and replacement.

[0048] The foregoing description of the specific exemplary embodiments of the present invention is for purposes of illustration and exemplification. These descriptions are not intended to limit the invention to the precise forms disclosed, and it is apparent that many changes and variations are possible in light of the above teaching.
