Problems solved by technology

[0003] There is internal resistance in the cable from the power supply to the robot, and the longer the distance, the greater the internal resistance. Because of Ampere’s theorem U=IR, when the load current of the robot increases, the loss voltage of the cable increases, and the input voltage of the robot decreases. When the input voltage Drop below the rated operating voltage of the robot, causing the robot to work abnormally
[0004] Since the output water pressure of the water source is constant, when there is a difference in height between the robot and the water source, the water pressure reaching the robot will be different, which will affect the application effect of the robot, such as the spray size of the nozzle

Abstract

The invention relates to a constant-pressure water and power supply device. The constant-pressure water and power supply device is applied to a high-altitude operation robot, the high-altitude operation robot comprises a water spraying device, and the water spraying device is configured to receive an external water source and spray water outwards in response to a received water spraying instruction. The constant-pressure water and power supply device comprises a water supply mechanism and a power supply mechanism, wherein the power supply mechanism is used for providing a constant-pressure power supply for the robot and the water supply mechanism, and the water supply mechanism is used for providing a water source for the robot and adjusting the pressure of the water source according to the water spraying pressure of the water spraying device, so that the water spraying pressure can be maintained within a preset pressure range. According to the constant-pressure water and power supply device, the cable voltage loss is effectively overcome, the water source design becomes simple, fine control is not needed, and only constant pressure needs to be given. Additionally, the water hammer effect is prevented from being generated by quickly opening and closing a valve so as not to cause damage to the water source, a water supply pipe and a valve. When the water pressure of the water using position of the robot changes, the water pressure is stably adjusted to an expected value. The invention further relates to a high-altitude operation mobile robot.

Description

technical field [0001] The invention relates to the technical field of robot control, in particular to a constant-pressure water supply power supply device and a mobile robot for aerial work. Background technique [0002] The existing high-altitude operation robot adopts the method of connecting water source and power supply from the roof or the ground, and will reach the robot through a long-distance cable to provide the required water and power resources for the robot. [0003] There is internal resistance in the cable from the power supply to the robot, and the longer the distance, the greater the internal resistance. Because of Ampere’s theorem U=IR, when the load current of the robot increases, the loss voltage of the cable increases, and the input voltage of the robot decreases. When the input voltage Drop below the rated working voltage of the robot, causing the robot to work abnormally. [0004] Since the output water pressure of the water source is constant, when t...
