[0027] With the help of the above technical solution, by setting up the inspection car box 1 and the driving wheel 2, and using the lifting component 4 to cooperate with the camera 3, the intelligent inspection device of the hydropower plant is convenient for monitoring the hydropower plant environment through the camera 3, and the inspection situation monitored by the camera 3 is timely fed back to the control system through the information transmission module, so that the staff can perform real-time monitoring. At the same time, the anti-collision component 5 provided can provide a buffer when it is hit during the inspection process. When the impact force is too large, the anti-collision component 5 will release the restriction on the protective tube 8 through the limiting component 7 while buffering, and under the action of the first spring force 9, it will quickly pop outward, thereby protecting the camera 3, thereby reducing the damage to the camera 3 due to excessive impact force, which is conducive to minimizing the loss in case of an accident.

[0028] like Figure 3 , Figure 4 and Figure 7As shown, in one embodiment, for the above-mentioned inspection device, two first slide groove openings are respectively opened on the left and right sides of the upper front end of the storage groove 101, and two second slide groove openings are respectively opened on the left and right sides of the lower front end of the storage groove 101. The anti-collision component 5 includes a tooth plate 52 slidably installed in the first slide groove opening, a support plate 53 slidably installed in the second slide groove, a first rotating rod 54 rotatably connected to the left and right side walls of the inner cavity of the inspection box 1, and two arc-shaped bent rods 58 distributed on the left and right sides of the inner cavity of the inspection box 1. The front ends of the tooth plate 52 and the support plate 53 pass through the storage groove 101 and are fixedly connected with the anti-collision plate 51 together. The left and right sides of the outer surface of the first rotating rod 54 are A first gear 55 is fixedly installed, and the rear end of the tooth plate 52 passes through the inspection box 1 and meshes with the first gear 55 on the same side. The first mounting block 56 and the second mounting block 57 are vertically fixedly installed at both ends of the arc-shaped curved rod 58 respectively. The first mounting block 56 and the second mounting block 57 are fixedly connected to the side wall of the inspection box 1 on the same side. A connecting block 510 is fixedly installed on the side of the first gear 55 close to the arc-shaped curved rod 58 on the same side, and an extrusion block 511 is fixedly installed on one end of the connecting block 510. The extrusion block 511 slides on the surface of the arc-shaped curved rod 58. A buffer spring 59 is sleeved on the outer surface of the arc-shaped curved rod 58, and the center of the arc-shaped curved rod 58 is located on the center line of the first rotating rod 54. It can be made that, during the inspection process of the inspection device, the anti-collision plate 51 is used to contact the object in advance and trigger the anti-collision component 5 when the inspection device collides with the object. When the anti-collision plate 51 is hit, it drives the tooth plate 52 and the support plate 53 to slide into the inspection car box 1, thereby driving the first gear 55 to rotate. The rotation of the first gear 55 drives the extrusion block 511 to slide on the surface of the arc-shaped bent rod 58 through the connecting block 510, and squeezes the buffer spring 59. The elastic force of the buffer spring 59 offsets the impact force, thereby avoiding damage to the inspection device caused by excessive impact force.

[0029] like Figure 4 and Figure 8As shown, in one embodiment, for the lifting assembly 4, the lifting assembly 4 includes a first motor 41, a plurality of screws 44, and a plurality of slide bars 46 arranged in the inner tube 12, the first motor 41 is fixedly installed on the bottom wall of the inspection vehicle box 1, and the output end of the first motor 41 is fixedly installed with a second gear 42, a limit plate 45 is fixedly installed in the middle of the inner wall of the inner tube 12, and a lifting plate 47 is slidably connected to the inner wall of the inner tube 12, and a plurality of screws 44 are evenly distributed around the second gear 42, and the lower end of the screw 44 is rotatably installed on the bottom wall of the inspection vehicle box 1, and the upper end of the screw 44 passes through the limit plate 45 and the lifting plate 47 in sequence and It is rotatably connected to the top wall of the inspection box 1, the screw rod 44 is threadedly connected to the lifting plate 47, the screw rod 44 is rotatably connected to the limit plate 45, the outer surface of the screw rod 44 is fixedly mounted with a third gear 43, the third gear 43 is meshed with the second gear 42, the sliding rod 46 is evenly distributed around the second gear 42, and the lower end of the sliding rod 46 is fixedly mounted on the bottom wall of the inspection box 1, the upper end of the sliding rod 46 passes through the limit plate 45 and the lifting plate 47 in sequence and is fixedly connected to the top wall of the inspection box 1, the sliding rod 46 is fixedly connected to the limit plate 45, the sliding rod 46 is slidably connected to the lifting plate 47, and the camera 3 is fixedly mounted on the upper end of the lifting plate 47. It can be made that, when preparing for inspection, the first motor 41 drives the second gear 42 to rotate, the second gear 42 drives the third gear 43 to rotate, the third gear 43 drives the screw 44 to rotate, the screw 44 drives the lifting plate 47 to move upward, thereby driving the camera 3 to extend upward from the through hole for detecting the surrounding environment. Similarly, when the inspection work is completed, the first motor 41 drives the second gear 42 to rotate in the opposite direction, which will drive the camera 3 to retract into the inner tube 12, so as to avoid the camera 3 being damaged by external collision when not in working state, thereby improving the service life of the entire device.

[0030] like Figure 4 As shown, in one embodiment, movable grooves 82 are provided on both the front and rear sides of the outer surface of the protective tube 8, a slot 81 is provided on the front surface of the outer surface of the protective tube 8 and located above the movable slot 82, and a movable opening 1101 opposite to the slot 81 is provided on the outer surface of the outer tube 11. The slot 81 and the limiting component 7 cooperate with each other to limit the protective tube 8, and the protective tube 8 is used to protect the camera 3 to avoid damage to the camera 3 when it is hit, thereby reducing the risk of damage to the camera 3.

The working principle and structure of the ratchet assembly 65 are the same as those of the bicycle flywheel, which will not be elaborated here. When the worm wheel 66 rotates, the first rotating rod 54 will be driven to rotate synchronously through the ratchet assembly 65. When the inspection device is working, when the anti-collision assembly 5 is hit, the toothed plate 52 drives the first rotating rod 54 to rotate through the first gear 55. The first rotating rod 54 and the worm wheel 66 are rotationally connected, and the first rotating rod 54 will not drive the worm wheel 66 to rotate. The worm 64 is meshed with the worm wheel 66. Before the inspection device performs inspection, the first motor 41 of the lifting assembly 4 drives the second gear 42 to rotate while driving the first bevel gear 61 to rotate. The first bevel gear 61 drives the second rotating rod 62 to rotate through the second bevel gear 63. The second rotating rod 62 drives the worm 64 to rotate. The worm 64 drives the ratchet assembly 65 to rotate in the opposite direction through the worm wheel 66. Under the action of the elastic force of the buffer spring 59, the extrusion block 511 is squeezed, thereby synchronously driving the first gear 55 to rotate in the opposite direction, and will not conflict with the rotation work of the ratchet assembly 65. A gear 55 drives the toothed plate 52 to move outward, thereby extending the anti-collision plate 51 from the storage groove 101. Similarly, when the first motor 41 drives the second gear 42 to rotate in the opposite direction, the first bevel gear 61 drives the second rotating rod 62 to rotate through the second bevel gear 63, thereby driving the worm wheel 66 to rotate through the worm 64, thereby driving the first rotating rod 54 to rotate through the ratchet assembly 65, thereby driving the first gear 55 to rotate, and the first gear 55 drives the toothed plate 52 to move inward, thereby storing the anti-collision plate 51 in the storage groove 101, reducing the footprint of the entire device and making it more practical.

An extrusion spring 77 is fixedly installed at the lower end of the slider 73. The extrusion spring 77 is fixedly connected to the bottom of the arc-shaped curved tube 71. A mounting plate 79 is fixedly installed on the outer surface of the first rotating rod 54. A pressure rod 710 is fixedly installed on one side of the outer surface of the mounting plate 79. When the anti-collision plate 51 is hit, it drives the tooth plate 52 to move into the inner inspection car box 1, thereby driving the first gear 55 to rotate, the first gear 55 drives the first rotating rod 54 to rotate, the first rotating rod 54 drives the mounting plate 79 to rotate, the mounting plate 79 drives the pressure rod 710 to rotate, the pressure rod 710 presses the limiting rod 76, and drives the arc rod 72 to shrink into the arc bent tube 71 through the slider 73, thereby driving the connecting rod 74 away from the slot 81.
