Detailed Description
The present invention will be described in further detail with reference to the following examples in order to make the objects, technical solutions and advantages of the present invention more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
The principle of application of the invention is described in detail below with reference to the accompanying drawings.
As shown in fig. 1 and 2, the helicopter cable hanging and screwing stopper is provided with a rigid frame 2, a gyroscope 1 is arranged in the middle of the frame 2, the end of the gyroscope 1 is connected with a motor 1-1 through a coupler, a storage battery 1-3 is fixedly arranged on the inner wall of the frame 2 outside the motor 1-1 through bolts, and the power end of the storage battery 1-3 is electrically connected with the motor 1-1 through a waterproof switch arranged on the frame 2;
The upper end of the frame 2 is movably provided with an upper hanging ring 3 through an upper bearing 1-2, and the lower end of the frame 2 is movably provided with a lower hanging ring 4 through a thrust bearing 1-4; the outer sides of the upper bearing 1-2 and the thrust bearing 1-4 are respectively provided with an oil seal 6.
The shaft coupling and the output shaft of the motor 1-1 are coaxial shafts.
The outer wall of the frame 2 is provided with a charging socket, and the storage battery 1-3 is electrically connected with the charging socket through a wire.
The frame 2 is provided with a steering wheel 5 at both ends thereof by means of mutually cooperating fasteners 2-2 and gaskets 2-1.
Fig. 2 is a schematic right-view structural diagram of a helicopter cable hanging cyclone stopper provided by another embodiment of the invention, as shown in fig. 2, two ends of the frame 2 are symmetrically connected with flywheels 7, and a waterproof shell is sleeved outside the frame 2; the upper and lower movable mounting of frame 2 has universal rings 10, and the middle part of universal rings 10 is provided with pivot 9.
The invention also provides a helicopter provided with the cable hanging and stopping rotary direction device, and the helicopter is connected with the cable hanging and stopping rotary device through a rope.
By utilizing the principle that the coupler of the gyroscope 1 keeps a fixed direction after the gyroscope 1 starts to work, the coupler of the gyroscope 1 is horizontally arranged, the coupler of the gyroscope 1 points to a fixed direction after working, and the gyroscope 1 is fixed in a rigid frame 2. The lower suspension ring 4 is connected to the frame 2 by means of thrust bearings 1-4, the lower suspension ring 4 being steerable with respect to the frame 2. In the practical application process, when a life-saving person hung under the frame 2 grabs the frame 2, the frame 2 is rotated forcefully, and the lower hanging ring 4 rotates relative to the frame 2 because the direction of the frame 2 is fixed, so that the life-saving person also turns. Thereby adjusting its own orientation. For better control of the direction, a multi-axis gyroscope 1 may be provided.
