Climbing walls is a very difficult task for ordinary people, but it is not very difficult for wall-climbing robots. In recent years, with the development of science and technology, there are many different adsorption methods for wall-climbing robots. Common ones include magnetic adsorption, negative pressure adsorption, and propeller push. Most people don’t know much about the adsorption principle of wall-climbing robots. Let’s come together find out.
1. Magnetic adsorption
Magnetic adsorption can be divided into permanent magnetic adsorption and electromagnetic adsorption. The principles of different magnetic adsorption are also different. Permanent magnetic adsorption is designed and installed with permanent magnetic materials at the bottom to form a magnetic bowl, which is then adsorbed on the metal wall. Electromagnetic adsorption uses the principle of electromagnetism. The magnetic field effect of the current generates magnetic force to adsorb on the wall. Although the magnetic force of electromagnetic adsorption is adjustable, it needs a large-scale machine to drive it due to its complex structure. The commonly used adsorption method is permanent magnet adsorption. This type of wall-climbing robot can work well on metal walls.
2. Negative pressure adsorption
Low-vacuum negative pressure adsorption adopts fan rotation to pump out the air in the negative pressure chamber to generate negative pressure for adsorption. It has certain wall adaptability, but has the disadvantages of high noise and large volume. The high-vacuum negative pressure adsorption method uses a vacuum pump to generate a certain degree of vacuum in the vacuum suction cup, which has the advantages of low noise and easy miniaturization and integration, but has high requirements for the smoothness and air permeability of the wall surface, and requires cleaning operations. The walls of ships are mostly uneven, with welding seams, old paint layers and other working conditions, so this adsorption method is limited.
3. Propeller push
Propeller pushing is also called propeller adsorption and rotor adsorption. This type of adsorption relies on the reasonable arrangement of propeller angles to generate thrust to attach the wall-climbing robot to the wall. This type of wall-climbing robot has a relatively simple structure, high noise and low efficiency, so the frequency of use is not high.
The wall climbing robot has a special adsorption structure design, so it can move on most walls. Whether it is a vertical wall, the surface of a large oil storage tank or the surface of a ship, the wall-climbing robot can handle it with ease and is highly adaptable. When using a wall-climbing robot for operation, the machine can reduce labor costs and improve work efficiency, and the work that needs to be completed for a long time can be completed in a short time. Wall-climbing robots can also reduce the risk factor of personnel to a certain extent, and can replace firefighters or inspection personnel to perform some high-altitude dangerous inspection projects.
