Description

A brake buffer device for a solar wing panel suspension device

technical field

The utility model relates to the technical field of solar wing ground simulation, in particular to a brake buffer device of a solar wing panel hanging device.

Background technique

The solar wing is the energy source of the satellite. The solar panel is a device that collects solar energy. It is usually used to supply energy for satellites and spacecraft, and can also be used to install on the top of environmentally friendly cars. 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 star rocket is separated, it is opened and the direction is constantly adjusted during the flight of the satellite, so that the solar cells are aligned with the sun to provide energy for the entire star. The solar wing monitoring camera can capture the deployment process and working status of the solar wing, and judge whether the solar wing is in normal condition; with the cooperation of attitude and orbit control, it can also capture images of the earth and the moon. In order to obtain better images of the Earth and the Moon, the camera uses a telephoto lens. Solar panels have two functions of power supply and charging, which is equivalent to a small power station. Solar panels and solar sails are not the same thing. Solar panels are a device that collects solar energy, while solar sails are spacecraft that use the light pressure of sunlight for space travel.

Solar panels are installed in space in a weightless environment. Therefore, when conducting various simulation experiments on the ground, we must hang them. In the ground environment, the solar panels cannot Normal operation and work; the solar wing panels and hinges and other connection mechanisms are designed according to the weightless environment. If the problem of gravity is not solved, the solar wing cannot work on the ground, so we must hang it when doing experiments on the earth. Hang it up, and ensure that the solar wing is suspended at the center of mass in a standard attitude, so as to offset the influence of gravity, and simulate the weightless environment of space to perform a series of actions.

Although space is a weightless environment, inertia still exists. Although the solar wing is not affected by gravity in space, it will still keep moving when it receives the effect of inertia when it is deployed. Its inertial impulse is through its hinges or other connection mechanism to offset. In the hanging deployment experiment of simulated solar panels on the ground, the solar panel is usually hung by a hanging device. When the hanging device moves, it drives the movement of the solar wing. There is no problem with the inertial motion itself, but if the solar wing is dragged by the suspension device for inertial motion, it is obviously in an abnormal posture. This inertial motion needs to be overcome, so it is necessary to use a limit device to adjust the suspension The device is limited. The inertial motion of the solar panel itself does not need to be interfered, but the inertial motion of the hanging device must be interfered to prevent the hanging device from moving forward in the stop position and dragging the solar panel to move or the sun due to the rebound of the hanging device. The situation where the flap is pulled back. In order to solve the problem of the hanging device moving forward or rebounding when braking, and because the problem of the forward rush or rebound movement of the hanging device itself cannot be completely solved, we have made a method to reduce this forward rush or rebound movement. The device, through the brake buffer device, absorbs the energy generated by the inertial motion of the suspension device, avoiding the repeated collision problem that occurs when the block is used to directly block the solar wing.

The conventional buffer device is afraid that the impact force will cause damage to the hanging device, so the impact on the hanging device is required to be very small. In the field of solar panel ground deployment, the anti-collision requirements of the hanging device are not very high. The anti-collision buffer is mainly for the solar wing under the hanging rope. The impact of the solar wing should be small, so it is mainly to offset the inertial force of the hanging device. When the solar wing is unfolded in place, the solar wing panel is locked by the locking mechanism. If buffering is performed in advance, the locking structure may not be locked normally. Therefore, the buffer device of the solar wing panel cannot have an intention to the unfolding locking mechanism of the solar wing panel, but once After the locking mechanism locks the solar wing, even if the solar wing continues to move forward for a certain distance, it will not affect the test of the solar wing, so it is different from the conventional anti-collision buffer device that must stop at the limit position , the buffering device of the solar wing plate starts to buffer at a certain position and can only perform a short period of buffering after buffering.
