Abstract

A climbing robot vehicle comprises a vehicle ( 2 ) and the front and rear ends of the vehicle body are provided with wheels ( 3 ). The end of the vehicle body facing towards the wall is fixedly connected to a sucking mechanism. The sucking mechanism comprises a body, the body being a hollow cylinder ( 4 ). A cover plate ( 5 ) is provided above the hollow cylinder. The upper end face of the cover plate is fixedly connected with the vehicle body and the lower end face of the cover plate is fixedly connected with the outer edge of the upper end face of the hollow cylinder by means of the first blocks ( 43 ) spaced from each other. The inner wall of the hollow cylinder is provided with tangential nozzles ( 41 ). The space between the first blocks ( 43 ) forms a first exhaust duct ( 44 ) between the outer edge of the upper end face of the hollow cylinder and the lower end face of the cover. A gap is formed between the lower end face of the hollow cylinder and the wall, and the gap forms a second exhaust duct ( 42 ) between the outer edge of the lower end face of the hollow cylinder and the wall. The climbing robot vehicle can be sucked on various kinds of walls and has a strong sucking ability and a wide application range.

First claim

What is claimed is:

1. A climbing robot vehicle capable of climbing a wall, comprising:
a vehicle; and
a sucking mechanism in connection with the vehicle, the sucking mechanism further comprising a hollow cylinder body and a cover plate connected to the hollow cylinder body via a plurality of first blocks,
wherein the inner wall of the hollow cylinder is provided with tangential nozzles,
wherein a first exhaust duct is formed by a space between the plurality of first blocks,
wherein a second exhaust duct is formed between the hollow cylinder body and the wall, and
wherein each of the first exhaust duct and the second exhaust duct connects the interior of the hollow cylinder body with the outer peripheral environment respectively.

2. The climbing robot vehicle of claim 1 , wherein the height of the first exhaust duct is adjustable.

3. The climbing robot vehicle of claim 1 , wherein the height of the second exhaust duct is adjustable.

4. The climbing robot vehicle of claim 1 , wherein the vehicle is provided with an electric motor which is connected to the cover plate, and wherein the hollow cylinder body and the cover plate are provided with pressure measuring holes in connection with pressure sensors.

5. The climbing robot vehicle of claim 1 , wherein the vehicle is connected with the hollow cylinder body by means of connecting rods.

6. The climbing robot vehicle of claim 1 , wherein the vehicle is provided with guide holes and a guide column configured to slide in the guide hole.

7. The climbing robot vehicle of claim 1 , wherein the hollow cylinder body is provided with a soft pad.

8. The climbing robot vehicle of claim 7 , wherein the soft pad is a bristle strip.

9. The climbing robot vehicle of claim 7 , wherein the lower part of the hollow cylinder body is provided with an annular baffle that is connected to the hollow cylinder body via a plurality of second blocks, wherein the space between the plurality of second blocks forms a third exhaust duct connecting the interior of the hollow cylinder body with the outer peripheral environment.

10. The climbing robot vehicle of claim 9 , wherein the plurality of first blocks are equally spaced, and the plurality of second blocks are equally spaced.

11. The climbing robot vehicle according to claim 1 , wherein said tangential nozzles are connected with a high pressure fluid source by a tube.
