Description

Technical Field

[0001] This application belongs to the field of helicopter rotor de-icing technology, specifically relating to a helicopter rotor de-icing structure. Background Technology

[0002] Helicopters typically fly at altitudes below 6,000 meters. Within this altitude range, they frequently encounter severe weather conditions such as rain, snow, and frost, and the liquid water content in the atmosphere is also relatively high. These factors can all contribute to the risk of icing for helicopters during missions.

[0003] The rotor of a helicopter is not only a lift component, but also undertakes major functions such as control. Icing on the rotor blade surface will directly threaten the safety of the helicopter. Utility Model Content

[0004] Purpose of the utility model: In view of the above-mentioned technical problems, this application provides a structure that can quickly and efficiently de-ic the helicopter, thus ensuring the flight safety of the helicopter.

A hydraulic cylinder is installed on one side of the hydraulic pump, and a piston rod is installed inside the hydraulic cylinder. The piston rod passes through the fixed base, and a guide sleeve is installed at the connection between the piston rod and the fixed base to improve the adaptability of the device.

[0007] Preferably, the working height of the de-icing device is precisely adjusted according to the actual height of the helicopter rotor through the coordinated operation of the hydraulic pump, hydraulic cylinder and piston rod in the lifting device, so as to ensure that the device can be adapted to different types of helicopters and improve the versatility and applicability of the equipment.

[0008] Preferably, the driving device includes a drive base, a drive motor, a threaded screw, and a shaft seat; The drive seat has a drive motor fixedly installed inside, a threaded screw fixedly installed on one side surface of the drive motor, a shaft seat installed on one side surface of the threaded screw, the shaft seat is fixedly connected to the inner wall of the slide groove, and the threaded screw passes through the drive seat and is placed inside the slide groove.

[0009] Preferably, the drive motor of the drive device drives the threaded screw to rotate, causing the de-icing device to move slowly along the slide, which can completely cover the rotor surface and achieve de-icing without dead angles; at the same time, the de-icing heating plate heats up simultaneously, quickly melting the ice and snow, greatly improving the de-icing efficiency.

[0010] Preferably, the de-icing device includes a wire seat, a de-icing frame, a temperature sensor, and a de-icing heating element; The bottom surface of the wire seat is fixedly equipped with a de-icing frame, inside which a temperature sensor is installed. The inner wall of the de-icing frame is fixedly equipped with a de-icing heating element. The temperature sensor monitors the rotor surface temperature in real time, and the control system dynamically adjusts the power of the de-icing heating element based on the temperature data. This effectively removes ice while preventing the rotor from overheating and being damaged, ensuring both the de-icing effect and protecting the rotor structure, thus extending its service life.

[0011] Preferably, there are two de-icing heating elements, and their positions are arranged in a mirror-symmetrical manner to improve the de-icing efficiency of the device.

A support frame is fixedly mounted on one side surface of the support platform, and a groove is provided on the top surface of the support frame.

Through the cooperation of a hydraulic pump, hydraulic cylinder, and piston rod in the lifting device, the height of the de-icing device can be precisely adjusted according to the rotor height, adapting to different helicopters and improving versatility. The motor of the drive device drives a lead screw, causing the de-icing device to move along the groove, covering the rotor surface. Combined with heating elements, this quickly melts the ice, improving de-icing efficiency. A temperature sensor monitors in real time, and the control system adjusts the power of the heating elements according to the temperature, protecting the rotor structure while effectively de-icing, extending its service life, and ensuring both de-icing effect and equipment safety.
