Description

Flexibly-connected three-dimensional solar sailboard mechanism Technical Field The invention relates to the technical field of space satellite energy supply, relates to a flexible-connection three-dimensional solar sailboard mechanism, and in particular relates to a flexible-connection tethered three-dimensional solar sailboard mechanism. Background The solar sailboard is used as a core energy device for the on-orbit operation of a satellite, a solar cell is attached to a substrate, solar energy is converted into electric energy by utilizing the photoelectric effect of the solar cell, continuous power support is provided for the whole-flow tasks such as attitude control, load work, orbit maintenance and the like of a satellite body, and the structural form and the connection mode of the solar sailboard directly determine the power generation efficiency, the attitude stability and the on-orbit service capability of the satellite and are key core components of satellite engineering design. The solar sailboard is divided into a rigid form and a flexible form according to the different structural rigidity of the base plate, and the solar cell array form can be divided into a unfolding design and a non-unfolding design under each form, so that the solar sailboard is generally divided into a body-mounted form, a rigid unfolding form, a rigid non-unfolding form, a flexible unfolding form and the like. The connection structure of the solar sailboard and the satellite body is divided into fixed connection, unfolding connection and movement connection. All 3 connection modes are rigid connection. For the body-mounted solar sailboard, the support solar cell and the solar cell circuit are directly fixed on the satellite surface. The body-mounted solar sailboard belongs to a kind of fixed connection. Other fixed connections include flanged installations, integral buttresses, and truss connections. For the expansion connection, the connection is generally by means of a hinge and a hinge plate. The movement connection means that the solar sailboard adjusts the direction along with the sun direction, and the connection mode is a driving mechanism, a driving joint and a linkage frame. As satellite functions become more powerful, the energy consumption of the satellite becomes larger, and the area of the solar sailboard is increased. Wei Xingti are mounted on solar cells with areas far below the power generated. The solar cells are then mounted outside the satellite body in a flat plate configuration, forming a solar array configuration. The transmission cost of a satellite is positively correlated with the weight of the satellite. In order to reduce the weight of the solar sailboard, a designer reduces the structural strength of the solar sailboard substrate, so that the fundamental frequency of the solar sailboard is lower, and the fundamental frequency of the solar sailboard exceeding 10 square meters is difficult to achieve more than 5 Hz. Meanwhile, in order to improve the power generation efficiency of the solar sailboard, some satellites are provided with rotating mechanisms between the solar sailboard and the stars. The satellite rotates the solar sailboard so that sunlight irradiates the solar sailboard at a vertical angle more closely. Originally, under space microgravity environment, the shaking problem of a large-area solar sailboard is a difficult problem for a satellite to control the pointing precision and stability of the satellite with high precision, and the stability of the attitude control is more difficult due to the participation of a rotating mechanism. In summary, the existing solar sailboard has the problems of low structural rigidity, low vibration fundamental frequency and low attitude control precision of the satellite caused by resonance with a satellite main body or flexible vibration. Disclosure of Invention The invention provides a flexible-connection three-dimensional solar sailboard mechanism, in particular to a flexible-connection tethered three-dimensional solar sailboard mechanism. The solar panel solves the problems that the solar panel has low structural rigidity and low vibration fundamental frequency, and is easy to cause resonance with a satellite main body or flexible vibration to cause the reduction of the attitude control precision of the satellite. The invention provides a flexible connection three-dimensional solar sailboard mechanism, which comprises: the solar panel comprises a panel body, a plurality of solar panels and a plurality of cone pairs, wherein the panel body is configured to perform solar photoelectric conversion and provide power supply for satellite on-orbit operation, the panel body is an inflatable shaping panel body, when a satellite and an arrow are separated and the panel body is unfolded on orbit, the panel body is formed into the multi-pyramid pairs from a folded state, cone bottoms of the multi-pyramid pairs are mutually attached and connected, and cone a
