Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example

[0026] In this embodiment, Figure 2 As shown, the end of the sliding column 13 away from the hollow plate 8 is rotatably connected to the push plate 12, and the push plate 12 is rotatably connected to the end away from the sliding column 13. The connecting block 11 is fixedly connected to the side of the connecting block 11 close to the vehicle body 1, and the side of the cross plate 10 close to the vehicle body 1 is symmetrically fixedly connected to the connecting column 19. The connecting column 19 is slidably connected to the vehicle body 1. When the cross plate 10 moves back and forth, the sliding column 13 can be driven to slide back and forth on the support plate 7 through the provided connecting block 11 and the push plate 12.

[0027] In this embodiment, Figure 4 As shown, the first springs 20 are symmetrically fixedly connected between the cross plate 10 and the vehicle body 1. The first springs 20 are all sleeved on the outer surface of the connecting column 19. When the cross plate 10 is subjected to a thrust, the first springs 20 will be pulled. When the thrust applied to the cross plate 10 disappears, the rebound force of the first springs 20 can drive the cross plate 10 to automatically reset.

[0028] In this embodiment, Figure 4 As shown, a cam 18 is attached to the side of the transverse plate 10 close to the vehicle body 1, and a rotating shaft 17 is passed through and fixedly connected to the cam 18. The rotating shaft 17 is rotatably connected to the lower end surface of the vehicle body 1, and a second bevel gear 16 is fixedly connected to the lower end of the rotating shaft 17. A first bevel gear 15 is meshedly connected to one side of the second bevel gear 16. The first bevel gear 15 is fixedly connected to the connecting shaft 14. When the connecting shaft 14 rotates, the first bevel gear 15 and the second bevel gear 16 are meshedly connected to each other, which can drive the rotating shaft 17 to rotate synchronously, so that the cam 18 connected to the outer surface of the rotating shaft 17 pushes the transverse plate 10 to move.

[0029] In this embodiment, Figure 5 As shown, the upper end surfaces of the extension plates 9 are symmetrically fixedly connected with second springs 22, and the ends of the second springs 22 away from the extension plates 9 are fixedly connected to the inside of the hollow plate 8. Both sides of the extension plates 9 are fixedly connected with fixed blocks 23, and the lower ends of the fixed blocks 23 are rollingly connected with rollers 24. Through the mutual cooperation between the rollers 24 and the second springs 22, the extension plates 9 can follow the slope of the ground and drive them to slide inside the hollow plate 8.

[0030] In this embodiment, Figure 1 As shown, a telescopic rod 2 is fixedly connected to the upper end surface of the vehicle body 1, a universal joint 3 is fixedly connected to the upper end of the telescopic rod 2, and a patrol device 4 is fixedly connected to the upper end of the universal joint 3. By setting the telescopic rod 2 and the universal joint 3, the height and angle of the patrol device 4 above the vehicle body 1 can be adjusted.

[0031] The effects achieved by this embodiment are as follows: In the prior art, due to the influence of natural factors, dust, fallen leaves and other debris will be generated on the ground of the power station, and there will be other construction or activities near the power station, which will also generate debris, such as construction dust, debris, etc. If the ground of the power station is not cleaned or maintained for a long time, the accumulated dust and other debris will gradually increase, forming obstacles to the movement of the inspection equipment. When the inspection equipment moves, these obstacles will be brought to the bottom of the equipment by the rotation of its moving wheels as the equipment moves, causing interference with the movement of the inspection equipment, affecting the normal movement of the inspection equipment, causing the inspection equipment to vibrate during the movement, increasing The probability of damage to the inspection equipment is increased, and the service life of the inspection equipment is reduced. Compared with the prior art, while the inspection equipment moves forward to inspect the power station, the two cleaning plates 21 can be driven to move back and forth at the front end of the auxiliary front wheel 6, so that the cleaning plates 21 can fit on the ground in front of the auxiliary front wheel 6, and clear the obstacles on the ground, effectively removing these potential interferences, ensuring the normal operation of the inspection equipment, and preventing debris from entering the bottom of the equipment, thereby reducing the probability of equipment damage, and also reducing the friction between the front and rear wheels and obstacles, reducing the wear degree of the front and rear wheels, thereby extending the service life of the inspection equipment;

[0032] Secondly, when the vehicle body 1 moves on a ground with a certain slope, the cleaning plate 21 can be driven to perform corresponding telescopic movement according to the change in the height of the slope, so that the cleaning plate 21 can always fit the ground, increase the applicability of the structure, ensure the normal operation of the cleaning plate 21 in the obstacle cleaning operation, and achieve adaptation to different slopes of the ground, thereby improving the cleaning efficiency of the obstacles.

[0033] The working process and principle involved in the overall content of the above embodiment are as follows:

[0034] When the staff needs to inspect the inside of the power station remotely, the power source inside the vehicle body 1 is first used to drive the rear wheel 5 to rotate, and cooperate with the auxiliary front wheel 6 to push the vehicle body 1 to move, and drive the vehicle body 1 to move into the power station. During the movement of the vehicle body 1, the auxiliary front wheel 6 will also rotate synchronously, driving the connecting shaft 14 connected between the auxiliary front wheels 6 to rotate synchronously on the vehicle body 1. When the connecting shaft 14 rotates, it can drive the first bevel gear 15 to rotate synchronously. At this time, through the mutual meshing connection between the first bevel gear 15 and the second bevel gear 16, the rotating shaft 17 connected to the second bevel gear 16 can be driven to rotate synchronously on the lower end surface of the vehicle body 1, and the cam 1 connected to the outer surface of the rotating shaft 17 is driven. 8 moves around the rotating shaft 17. As the cam 18 moves, the cam 18 and the side wall of the cross plate 10 fit together. Therefore, when the protruding part of the cam 18 moves and contacts the cross plate 10, the cross plate 10 is pushed to move horizontally away from the vehicle body 1, driving the connecting column 19 to slide out from the inside of the vehicle body 1 and pulling the first spring 20 connected between the cross plate 10 and the vehicle body 1. When the protruding part of the cam 18 is separated from the cross plate 10, the rebound force of the first spring 20 pulls the cross plate 10 to automatically approach the vehicle body 1, so that the cross plate 10 and the cam 18 are always in contact with each other. Moreover, the cam 18 and the first spring 20 cooperate with each other, and as the rotating shaft 17 rotates, the cross plate 10 can be driven to move back and forth horizontally.

[0035] During the horizontal reciprocating movement of the cross plate 10, the connecting block 11 connected to the side wall can push one end of the two push plates 12 to move synchronously, so that the push plates 12 can reciprocate between the inclined state and the horizontal state, driving the sliding column 13 connected to the side of the push plate 12 away from the connecting block 11 to slide reciprocatingly horizontally on the support plate 7. During the movement of the sliding column 13, the hollow plate 8 and the extension plate 9 can be used to drive the cleaning plate 21 to reciprocate in front of the auxiliary front wheel 6 to remove the particles in front of the auxiliary front wheel 6, thereby ensuring the normal operation of the inspection equipment and preventing debris from entering the bottom of the equipment, thereby reducing the probability of equipment damage, and also reducing the friction between the front and rear wheels and obstacles, reducing the wear of the front and rear wheels, thereby extending the service life of the inspection equipment;

[0036] When the vehicle body 1 moves, due to the uneven flatness of the ground, there will be a certain slope. When the vehicle body 1 drives the auxiliary front wheel 6 to move to the upward slope, the roller 24 connected to the side wall of the extension plate 9 will preferentially contact the upward slope. The roller 24 is blocked by the upward slope and will push the extension plate 9 to slide into the hollow plate 8, squeezing the second spring 22 between the extension plate 9 and the hollow plate 8. When the vehicle body 1 drives the auxiliary front wheel 6 to move to the downward slope, the rebound force of the second spring 22 will push the extension plate 9 to automatically slide out of the hollow plate 8. The cleaning plate 21 at the lower end of the extension plate 9 can always fit the ground, and when the vehicle body 1 moves, the roller 24 will roll synchronously on the lower end surface of the fixing block 23, and will not hinder the movement of the vehicle body 1, so that the cleaning plate 21 can be driven to move accordingly according to the height change of the ground slope, so that the cleaning plate 21 can always fit the ground, increase the applicability of the structure, ensure the normal operation of the cleaning plate 21 in the obstacle cleaning operation, and achieve adaptation to different slopes of the ground, thereby improving the cleaning efficiency of the obstacles;

[0037] When the vehicle body 1 is moved to the interior of the power station for inspection, the staff can adjust the inspection device 4 connected to the top of the universal joint 3 by remotely controlling the telescopic rod 2 to extend and retract and the universal joint 3, so that the inspection device 4 can be raised and lowered or tilted synchronously, so that the staff can carefully inspect all directions inside the power station.
