Description

Technical Field

[0001] The invention belongs to the technical field of limited space operation, and in particular to an anti-rotation and anti-swing hoisting device based on a turbofan. Background Art

[0002] During the rescue and medical transfer process, the injured person may rotate or swing back and forth during hoisting due to factors such as wind force and inertia. This rotation and swing not only affects the safety of hoisting, but may also cause secondary injuries. Especially in confined space operations (such as mines, tunnels, underground facilities, etc.), due to the small space and complex environment, traditional anti-rotation and anti-swing methods may not be flexible or efficient. Therefore, the development of a hoisting stretcher system that can adjust in real time and effectively prevent rotation and swing is of great significance to improving the safety and stability of rescue and medical transfer. Summary of the invention

[0003] The purpose of the present invention is to overcome the shortcomings of the prior art and propose an anti-rotation and anti-swing hoisting system based on turbofans. By installing several small, low-noise turbofans on the stretcher, combined with high-precision gyroscope sensors and intelligent control systems, the posture of the stretcher is monitored and adjusted in real time to prevent the injured person from rotating and swinging during the hoisting process. Each turbofan and main controller has its own power supply (battery) and communicates stably through the StarFlash wireless communication protocol. The operator can choose to turn the anti-rotation and anti-swing functions on and off through a remote terminal (such as a smart phone, tablet computer, etc.), thereby achieving flexible and efficient control. This innovative design significantly improves the safety and comfort of hoisting, and is particularly suitable for various complex rescue and medical transfer scenarios, especially in confined space operations, and can effectively improve emergency response capabilities and safety.

[0006] Moreover, the turbofan is symmetrically installed at the bottom of the stretcher. At the same time, the turbofan uses a small, low-noise turbofan that is soft and fits the human body to ensure comfort and safety, and is firmly fixed to prevent loosening or falling off during lifting.

[0007] Moreover, the sensor uses a gyroscope, and the number of sensors is the same as the number of turbofans. Each turbofan is equipped with a high-precision, low-noise gyroscope; the sensor is fixed at a key position of each turbofan to ensure that it is firmly installed and not affected by mechanical vibration; the sensor is used to monitor the posture changes of the stretcher in real time, including the tilt angle and angular velocity.

[0008] Moreover, the main controller adjusts the working state of the turbofan according to the data provided by the sensor to control the direction and stability of the stretcher; at the same time, the data acquisition module of the main controller periodically receives angular velocity data from each sensor; a Kalman filter is used to improve the accuracy of attitude estimation; and a control algorithm is used to generate control instructions, which are sent to each turbofan through the Star Flash wireless communication module.

[0009] Furthermore, the main controller provides anti-rotation and anti-sway functions:

[0010] Anti-rotation function: The operator can choose to turn on or off the anti-rotation function through the remote terminal; when the anti-rotation function is turned on, the system will automatically adjust the working state of the turbo fan according to the angular velocity changes detected by the gyroscope to prevent the stretcher from rotating;

[0011] Anti-sway function: The operator can choose to turn on or off the anti-sway function through the remote terminal; when the anti-sway function is turned on, the system will automatically adjust the working state of the turbo fan according to the angular velocity changes detected by the gyroscope to prevent the stretcher from swinging.

[0012] Moreover, the power source is an independent portable battery; each turbo fan and main controller are equipped with an independent portable battery; at the same time, the battery is managed by a battery management system, which includes power monitoring and low-battery alarm functions to ensure the continuous operation of the system.

[0013] Moreover, the wireless communication module adopts the Star Flash wireless communication protocol to ensure stable communication between turbo fans; at the same time, the Star Flash protocol supports multi-hop communication and provides reliable network coverage in complex environments.

[0014] Moreover, the remote control terminal is connected to the main controller via the Star Flash wireless communication protocol; the operator performs remote control through the application on the remote terminal and chooses to turn the anti-rotation and anti-sway functions on and off; at the same time, the remote terminal displays real-time posture data and system status, which is convenient for the operator to monitor and adjust.

[0015] The advantages and positive effects of the present invention are:

[0016] The present invention uses a high-precision gyroscope sensor to monitor the posture changes of the stretcher in real time, and combines with an intelligent control system to dynamically adjust the working state of the turbofan. The system can effectively prevent the injured person from rotating and swinging during the hoisting process, and significantly improves the safety and stability of the hoisting. Especially in confined space operations (such as mines, tunnels, underground facilities, etc.), this innovative design not only improves the efficiency of rescue and medical transfer, but also greatly reduces the risk of secondary injuries. In addition, the remote control function allows the operator to perform precise control from a safe distance, further enhancing the flexibility and practicality of the system. Overall, the invention provides reliable technical support for emergency response in complex environments, and significantly improves the overall safety and comfort of rescue and medical transfer.
