[0051] In example two, on the basis of example one, as shown in Figure 7 and Figure 8 The automatic unlocking mechanism 7 comprises a push-pull electromagnet 701 installed on the rear side of the power distribution cabinet body 1, and the push-pull electromagnet 701 is located at the bottom of the automatic locking mechanism 6, the front end of the push-pull rod of the push-pull electromagnet 701 is fixedly connected with a pull rope 702, and the other end of the pull rope 702 is fixedly connected with the front end of the pulling rod 604, the pull rope 702 is slidably connected with a pulley 703, the pulley 703 is installed on the rear side of the power distribution cabinet body 1 through a support 704, and the rear end of the support 704 is fixedly connected with a U-shaped limiting plate 705; an arc-shaped notch is formed in the rear side of the U-shaped limiting plate 705, and the arc-shaped notch is located outside the pulley 703, the pull rope 702 is located inside the U-shaped limiting plate 705, through the arrangement of the U-shaped limiting plate 705, the pull rope 702 can be effectively guided and limited, avoiding the pull rope 702 from being separated from the pulley 703, and the reliability of the automatic unlocking mechanism 7 during use is improved; through the arrangement of the automatic unlocking mechanism 7, when it is necessary to release the sealing, only the push-pull electromagnet 701 needs to be powered, so that the rear end of the plug-in block 603 can be quickly pulled out of the rectangular socket 209, the limiting rod 208 is unlocked, then the lifting frame 201 drives the bottom sealing plate 4 to move downward and reset, and the side sealing plates 302 on both sides are simultaneously moved upward and reset, so that the sealing is quickly released, and since it is not necessary to control the motor 5 to operate in reverse, the operation process is significantly simplified.

[0052] The working principle of the present application is as follows: when it rains, the raindrop sensor 104 senses the rain and transmits a signal to the controller 103, at this time, the controller 103 controls the driving motor 5 to rotate a certain number of turns, and the reel 501 rotates a certain number of turns, thereby winding the rope 502, and the lifting frame 201, the lower U-shaped connecting plate 203 and the bottom sealing plate 4 are lifted, at this time, the guide sliding cylinder 202 and the external spring of the supporting sliding column 101 are in a compressed state, then the lower U-shaped connecting plate 203 drives the lower end of the lever 204 to rotate upward, under the action of the supporting frame 2011, the upper end of the lever 204 rotates downward, thereby driving the upper U-shaped connecting plate 205, the driving plate 206, the connecting sliding rod 303 and the side sealing plate 302 to move downward synchronously, when the frame-shaped sealing rubber gasket 401 on the bottom sealing plate 4 is in close contact with the bottom end face of the power distribution cabinet body 1, the side sealing plates 302 on the left and right sides of the power distribution cabinet body 1 cover the heat dissipation holes on the left and right sides of the power distribution cabinet body 1, so that the corresponding heat dissipation holes are effectively sealed to prevent rainwater from entering the inside of the power distribution cabinet body 1, and during sealing, only the lower U-shaped connecting plate 203, the lever 204, the upper U-shaped connecting plate 205 and the supporting frame 2011 are needed to drive the bottom sealing plate 4 and the side sealing plate 302 to perform sealing operation, so that the overall structure is simplified, and even if leaves and other debris fall on these structures, they are not easy to jam these structures, which significantly improves the reliability of waterproof sealing, and only one driving motor 5 is needed to drive, which effectively saves the manufacturing cost and energy consumption.

[0053] When the bottom sealing plate 4 seals the bottom of the power distribution cabinet body 1, the rectangular sliding block 602 drives the plug-in block 603 to move backward rapidly under the action of the spring force of the pull rod 604, so that the rear end of the plug-in block 603 is automatically inserted into the rectangular socket 209, at this time, the limiting rod 208 is effectively limited on the rear side of the power distribution cabinet body 1, so that the bottom sealing plate 4 and the side sealing plate 302 are more stable and reliable during sealing operation, and the phenomenon of the lifting frame 201 falling back after the driving motor 5 stops rotating is avoided.

[0054] When it is necessary to unseal, only the push-pull electromagnet 701 is powered, so that the push-pull rod on the push-pull electromagnet 701 drives the lower end of the pull rope 702 to move backward, thereby pulling the pull rod 604, the rectangular sliding block 602 and the plug-in block 603 to move forward, so that the rear end of the plug-in block 603 is pulled out of the rectangular socket 209, so that the limiting rod 208 loses the limiting function, then under the action of the spring force of the guide sliding cylinder 202 and the supporting sliding column 101, the lifting frame 201 moves downward to the original position, at the same time, the side sealing plates 302 on both sides also move upward to the original position, so that the sealing can be quickly removed, and during the unsealing process, the driving motor 5 does not need to operate in reverse, so that the operation process is more simple and convenient, and the response efficiency is higher.
