as shown in fig. 1, the unfolding mechanism of the pull-wire umbrella antenna is provided with a pull-wire mechanism on each of the upper and lower sides of the umbrella antenna, each pull-wire mechanism includes a base and a boss cover, and a plurality of rows of mounting holes are circumferentially and uniformly distributed around a certain point on the upper surface of the base.

As shown in fig. 2, which is a schematic cross-sectional view of a pull-wire umbrella antenna structure, there are n tension pull wires in total, where n is a positive integer, and n is greater than or equal to 30 and less than or equal to 40, the illustrated structure is implemented by taking 32 tension pull wires as an example, eight rows of mounting holes are uniformly distributed on the upper surface of a cylindrical base 1 around the center of the cylindrical base 1 as the center, and four pairs of mounting holes are equidistantly distributed along the edge of the base 1 from the center of the base 1, so that 32 pull wire control units are fixed on the upper surface of the base.

In the unfolding process of the umbrella-shaped antenna, working parameters of each power device are set to be the same, namely the torque output by each output shaft is the same, and then the power is transmitted to the corresponding rotating shaft 10 through the coupler to drive each rotating shaft 10 to rotate at the same rotating speed, so that the stretching amount of a tension stay wire wound on a winding coil can be effectively changed, and the synchronous unfolding of the stay wire type umbrella-shaped antenna can be ensured; the specific power transmission route is that when the pull-type umbrella-shaped antenna 8 is uniformly unfolded, the pull-line mechanism positioned at the lower side of the umbrella-shaped antenna 8 tensions a tension pull-line 7, the pull-line mechanism positioned at the upper side of the umbrella-shaped antenna 8 relaxes the tension pull-line 7, when the power device is used specifically, the parameters of the power device 9 of the upper pull-line mechanism are set to be the same, the parameters of the power device 9 of the lower pull-line mechanism are also set to be the same, during the unfolding process, the motor in the lower pull-line mechanism is in forward rotation to tension the tension pull-line 7, the motor in the upper pull-line mechanism is in reverse rotation to relax the tension pull-line 7, the four rotating shafts 10 rotate at the same rotating speed, the tension pull-line 7 sequentially passes through the wire outlet 4, the electric control push rod 3 and the wire guide tube 5 to be wound on the winding coil 2, the pull-type umbrella-type antenna 8 is uniformly unfolded, and after the power device 9 stops working after the umbrella-line is unfolded to a certain degree, the unfolded shape is kept unchanged, after the unfolding is finished, if the shape of a certain unfolded region is finely adjusted, the electric control push rod 3 is started, the electric control push rod 3 is controlled by a control switch, 32 buttons are arranged, each button controls one electric control push rod 3, and the length of an effective working line segment of each tension stay wire is changed through the stretching of the electric control push rod 3 so as to achieve the required purpose. On the contrary, the tension guy wire 7 is tightened by the positive rotation of the motor in the upper guy wire mechanism and the tension guy wire 7 is loosened by the negative rotation of the motor in the lower guy wire mechanism, so that the umbrella-shaped antenna is closed. The working principle of the two wire drawing mechanisms is the same, and the concave-convex surface regulation and control of the wire drawing type umbrella-shaped structure can be accurately realized through the mutual matching work.

In summary, the present invention provides a deployment mechanism for a guyed umbrella antenna, which precisely and individually controls the shape of an umbrella cover of the umbrella antenna after the satellite umbrella antenna is synchronously deployed, so that the deployment mechanism has higher deployment performance and more reliable storage ratio and deployment accuracy.
