The two monitoring electrodes are arranged in the monitoring groove, the corresponding cover plate is arranged on the outer side of the monitoring groove, the first hollow part is arranged on the cover plate, the cover plate is matched with the monitoring groove to protect the monitoring electrodes, and meanwhile, the first hollow part is arranged, so that normal inlet and outlet of water flow can be ensured.

This utility model discloses an electric vertical takeoff and landing manned aircraft, including an aluminum alloy frame, a vibration damping assembly, a right guardrail connected to one side of the aluminum alloy frame, and a left guardrail connected to the other side via a pivot seat. The vibration damping assembly includes a first carbon fiber tube and a vibration damping seat fitted on the first carbon fiber tube. The upper and lower vibration damping seats are fastened with bolts through the penetration between the first carbon fiber tube and the aluminum alloy frame. The rubber vibration damping pad absorbs high-frequency vibration energy through its own elastic deformation, effectively blocking the direct transmission of vibration to the frame. The axial anti-roll bracket forms an elastic clamp on the sleeve through rubber clips. This clamping force can be flexibly adjusted by the hardness of the rubber clips, which greatly reduces the vibration felt in the cockpit area. Both the first and second carbon fiber tubes are made of carbon fiber composite material, which has a weak ability to reflect sound waves and can reduce the transmission efficiency of propeller aerodynamic noise.
