Motion platform for underwater steep slope and underwater detection robot

Abstract

The invention relates to a motion platform for an underwater steep slope and an underwater detection robot based on the motion platform. The motion platform comprises a platform body, a motion mechanism, a driving device and a propeller, wherein the motion mechanism is used for supporting the platform body and driving the platform body to do motion on the slope surface of the steep slope; the driving device is used for driving the motion mechanism; the propeller is arranged on the platform body and is used for exerting downward pressure on the platform body, and an inclined angle of 45-90 degrees is formed between the direction of the downward pressure exerted on the platform body and the slope surface of the steep slope on which the platform body is positioned. Compared with the prior art, the motion platform disclosed by the invention has the advantages that the propeller exerts the definite downward pressure on the platform body, so that the platform body is always pressed on the slope surface firmly when doing motion along the slope surface, the phenomenon that the motion platform slides off from the slope surface is avoided, besides, the phenomenon that underwater gravels are raised is not caused, the situation that the detection robot has favorable motion reliability is guaranteed, and stable carrying conditions are provided for detection tasks.

Problems solved by technology

Since it is inevitable to encounter slopes during the detection process, when the detection equipment detects the slope, the detection equipment needs to move along these slopes, and the existing detection equipment is generally wheeled. Or the crawler structure, so once the angle of the slope is large, for example: when detecting the dam surface of the dam, because the dam surface not only has a large slope, but also has sediment, moss and other debris, As a result, the friction coefficient of these testing equipment on the slope will be seriously reduced, causing the testing equipment to gradually lose its grip as the slope increases, and eventually slip down from the slope and fail to complete the detection

[0003] In order to solve the above-mentioned technical defects, the existing method is to add a suction cup to the detection equipment, and use the suction of the suction cup to suck the slope, but it is found in actual use that most of the slopes are generally uneven. , so when the suction cup absorbs the slope, water will continuously enter the suction cup, which will affect the suction of the suction cup and eventually cause the detection equipment to slip

Moreover, when the suction cup is working, it usually uses the internal water pump to continuously pump water to the outside to complete the adsorption of the slope surface, so a large amount of sand and gravel are often raised during the adsorption, causing the water to be turbid, which seriously affects the imaging quality of the detection equipment
