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

The invention claimed is:

1. A climbing robot vehicle capable of climbing a wall, the robot vehicle comprising: a vehicle, front and rear ends of the vehicle being provided with wheels; a side of the vehicle facing towards the wall being fixedly connected to a sucking mechanism, which comprises a body, wherein the body is a hollow cylinder; a cover plate being provided above the hollow cylinder; an upper end face of said cover plate being fixedly connected with the vehicle and a lower end face of the cover plate being fixedly connected with an outer edge of an upper end face of the hollow cylinder by means of first blocks spaced apart from each other; an inner wall of the hollow cylinder being provided with tangential nozzles; a space between said first blocks forming a first exhaust duct between the outer edge of the upper end face of the hollow cylinder and the lower end face of the cover plate; a gap being formed between a lower end face of the hollow cylinder and the wall, the gap forming a second exhaust duct between an outer edge of the lower end face of the hollow cylinder and the wall; the first exhaust duct and the second exhaust duct connecting an interior of the hollow cylinder with an outer peripheral environment.

2. The climbing robot vehicle according to claim 1 , wherein the upper end face of the vehicle is provided with an electric motor that is connected to the cover plate by means of a screw it drives; the screw being connected to a screw thread of the cover plate; the hollow cylinder and the cover plate being provided with pressure measuring holes; and the pressure measuring holes being connected with pressure sensors.
