Description

Technical Field

[0001] The utility model relates to the technical field of spacecrafts or satellites, in particular to a reel-type flexible solar wing substrate and a winding structure. Background Art

[0002] The solar wing is the energy source of a satellite. That is, the solar panel, which is a device for collecting solar energy. The solar wing is the energy source of the satellite. When the satellite is launched, the solar wing is in a folded state. After the separation of the satellite and the rocket, it is unfolded and continuously adjusts its direction during the flight of the satellite to align the solar cells with the sun, providing energy for the operation of the whole satellite. The solar wing is usually installed on the substrate.

[0003] If the traditional rigid substrate or semi-rigid substrate is still used on large-area solar cell wings, problems such as the envelope size and weight after folding cannot meet the requirements will occur, which will affect the flight of satellites and spacecrafts;

[0004] In the prior art, through retrieval, for example, in the Chinese patent with the publication number CN213292736U, a roller is used to wind the flexible solar wing. When winding, it is not convenient to fix the head end, and the winding efficiency and effect are poor;

[0005] When winding a long strip-shaped flexible solar wing substrate, due to the change of the winding length, its tension will also change. When the tension is too large or too small, it will affect the winding of the flexible solar wing substrate. Summary of the Utility Model

[0006] The purpose of the utility model is to solve the disadvantages in the prior art that the envelope size and weight after folding cannot meet the requirements, it is not convenient to fix the head end, the winding efficiency and effect are poor, and with the change of the winding length, it will affect the winding of the flexible solar wing substrate, and a reel-type flexible solar wing substrate and a winding structure are proposed.

[0007] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0008] A reel-type flexible solar wing substrate, including a roller, a reel-type solar wing substrate is wound around the circumference of the roller, a through opening is provided on one side of the circumference of the roller, fixing pieces are respectively provided on both sides of the opening, and the fixing pieces are fixedly connected to the inner wall of the circumference of the roller;

[0009] The roller is made of elastic material, and a plurality of screws are threadedly connected between the two fixing pieces, and the plurality of screws all penetrate through the solar wing substrate.

[0010] In a possible design, the winding structure includes a bottom plate on one side of the solar wing substrate. A sliding plate is slidably connected to the upper surface of the bottom plate. A vertical plate is fixedly connected to the upper surface of the sliding plate. A motor is fixedly connected to one side of the vertical plate. One end of the output shaft of the motor is fixedly connected to an air shaft. The air shaft penetrates through the vertical plate. The air shaft is used for winding the solar wing substrate. A plurality of static rollers are rotatably connected to one side of the vertical plate. A through chute is provided on one side of the vertical plate. A moving roller is slidably connected in the chute. The solar wing substrate is drivingly connected between the plurality of static rollers and the moving roller. A first cylinder is rotatably connected to one side of the vertical plate. One end of the piston rod of the first cylinder is rotatably connected to the moving roller.

[0011] In a possible design, a second cylinder is fixedly connected to the upper surface of the vertical plate. One end of the piston rod of the second cylinder is fixedly connected to a pressing plate. The pressing plate is located on the upper surface of the solar wing substrate. A fixing plate is fixedly connected to one side of the vertical plate. The fixing plate is located at the bottom of the solar wing substrate. The fixing plate and the pressing plate are symmetrically arranged.

[0012] In a possible design, an adjusting rod is threadedly connected to the upper surface of the vertical plate. An abutting plate is rotatably connected to the circumference of the adjusting rod. The abutting plate is located on one side of the solar wing substrate.

[0013] In a possible design, a screw rod is rotatably connected to one side of the bottom plate. The screw rod is threadedly connected to the sliding plate. Two sliders are fixedly connected to the bottom of the sliding plate. The two sliders are respectively located on both sides of the screw rod. The two sliders are respectively slidably connected to the upper surface of the bottom plate.

[0016] When winding the flexible solar wing substrate, it is fixed on the air shaft. The motor is started to drive the air shaft to rotate, and the solar wing substrate is wound around the plurality of static rollers and the moving roller (the specific winding method can refer to the attached drawings), which is convenient for continuous winding of the solar wing substrate.
