Description

Technical Field

[0001] This utility model belongs to the field of spacecraft technology, and specifically relates to a solar array deployment frame with adjustable attitude and stable buffer. Background Technology

[0002] During spacecraft development, multiple ground deployment tests of the solar array are required to verify its performance indicators. Given that solar array deployment in orbit occurs in a weightless environment, measures must be taken during testing to mitigate the effects of ground gravity. As spacecraft assembly precision increases, the accuracy requirements for ground assembly and testing equipment also rise. Current solar array deployment frames have several issues that require improvement:

[0003] 1. Currently used solar array deployment frames have problems such as gaps between structures after telescopic adjustment and poor accuracy of repeated positioning;

[0004] 2. Currently used solar array deployment frames have a problem of swaying after telescopic adjustment and during ground tests;

[0005] 3. Currently used solar array deployment frames have issues with the accuracy of adjusting the attitude and orientation of the solar arrays. Summary of the Invention

[0006] Therefore, this utility model was made in view of the above problems, and the above objectives are achieved through the following technical solutions:

[0007] An adjustable and stabilized solar panel deployment frame includes: a solar panel support, which comprises: a base, a stabilizing adjustment rod, and a dual-axis adjuster. The base is placed on the ground, and the stabilizing adjustment rod is fixedly placed above the base. The stabilizing adjustment rod includes: a hydraulic pusher, a spring, an electromagnet, a permanent magnet, and a telescopic support column. The hydraulic pusher is fixedly placed inside the cavity of the stabilizing adjustment rod. One end of each spring is connected to the top of the hydraulic pusher, and the other end is connected to the bottom of the telescopic support column. The electromagnet is fixedly placed on the bottom surface inside the telescopic support column, and the permanent magnet is fixedly placed on the top surface inside each telescopic support column. The dual-axis adjuster includes: a crossbeam, a motor, a screw, a guide rail, a slider, a slide block, and a suspension device. There are two crossbeams, which are perpendicular to each other. The motor is fixedly placed inside one end of the crossbeam, and a screw is provided on the motor drive end. A guide rail is provided inside the crossbeam, and a slider slides inside the guide rail. The lower end of the slider is embedded in the center of the slide block, and a suspension device is fixedly placed at the bottom of the slide block.

[0008] Preferably, a sensor is provided below the spring, the telescopic support column is a telescopic sleeve structure and is hollow inside, and the telescopic support column is fixedly installed above each hydraulic pusher.

[0009] Preferably, all the crossbeams are hollow prisms, one of which is fixedly installed on the upper end of the telescopic support column, and the other is installed below the previous crossbeam through a sliding seat.

[0010] Preferably, the number of slide blocks, suspension devices, and sliders are the same, and the slide block has a screw hole in the middle that engages with the screw rod.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. This utility model uses the coordinated operation of springs, electromagnets, permanent magnets, telescopic support columns, and other structures to tighten the adjusted solar wing deployment frame, ensuring sufficient repeatability and positioning accuracy while the structures are in relative motion.

[0013] 2. During the operation of the solar array deployment frame, it is subjected to the gravity generated by the onboard satellite and external forces applied during ground experiments, which may cause the deployment frame to deform under stress. Under these circumstances, the stress on the device's stabilization adjustment rod will increase. By collecting and feeding back this stress information through sensors, the magnetic force of the electromagnets can be adjusted, thereby responding in advance to the increased stress and improving overall stability.

[0014] 3. This utility model uses a hydraulic pusher and a dual-axis adjuster to adjust the orientation and attitude of the crossbeam, thereby controlling the orientation and attitude of the solar panels on it. The adjustment effect is stable, and the adjustment accuracy is ensured by the action of the stabilizing adjustment rod. Attached Figure Description

However, this utility model can also be implemented in various different forms, and therefore is not limited to the embodiments described below.

[0022] like Figure 1-5 As shown, a solar array deployment frame with adjustable attitude and stable buffer includes: solar array support 1;

[0023] The solar panel support 1 includes: a base 11, a stabilizing adjustment rod 12, and a dual-axis adjuster 13;

[0024] There are two bases 11, which are respectively set on the ground. The bases 11 are equipped with casters and lowerable supports for moving the bases 11.

[0025] The stabilizing adjustment rod 12 is a hollow prism with a gap in the middle, and there are two of them, which are fixedly installed above the base 11.

[0026] The stabilizing adjustment rod 12 includes: a hydraulic pusher 121, a spring 122, an electromagnet 123, a permanent magnet 124, and a telescopic support column 125;

[0027] The hydraulic pushers 121 are four in number and are fixedly installed in the cavity of each stabilizing adjusting rod 12.

[0028] There are four springs 122, one end of each spring 122 is connected to the top of the hydraulic pusher 121, and the other end is connected to the bottom of the telescopic support column 125.

[0029] The spring 122 has a sensor located below it;

[0030] The number of electromagnets 123 is four, and they are respectively fixedly installed on the bottom surface inside each telescopic support column 125;

[0031] The number of permanent magnets 124 is four, and they are respectively fixedly installed on the top surface inside each telescopic support column 125;

[0032] There are four telescopic support columns 125, which are telescopic fitting structures and are hollow inside. The telescopic support columns 125 are fixedly installed above each hydraulic pusher 121.

[0033] The dual-axis adjuster 13 includes: a crossbeam 131, a motor 132, a screw 133, a guide rail 134, a slider 135, a slide block 136, and a suspension device 137.

[0034] There are two crossbeams 131, which are hollow prisms. One of them is fixedly mounted on four telescopic support columns 125 to connect the two bases 11. The other is mounted below the previous crossbeam 131 through a sliding seat and is perpendicular to it.

[0035] There are two motors 132, which are fixedly installed inside the cantilever end of each crossbeam 131.

[0036] There are two screws 133, which are fixedly installed on the drive end of each motor 132 and are horizontally installed inside the crossbeam 131.

[0037] There are two guide rails 134, which are fixedly installed inside each crossbeam 131 and below the screw 133 respectively;

[0038] The number of sliders 135 is in two sets, with three in each set (which can be increased or decreased according to actual needs), and they are respectively movably set on each guide rail 134;

[0039] The slider 135 is embedded in the center of the slide block 136;

[0040] The number of slide blocks 136 is the same as that of sliders 135. Each slide block 136 has a screw hole in the middle that fits with the screw rod 133. Each slide block 136 is set on each screw rod 133.

[0041] The number of suspension devices 137 is the same as that of sliders 135, and they are fixedly installed at the bottom of slide block 136.

[0042] The working principle of this utility model;

[0043] In use, the suspension device 137 first suspends the device under test. The hydraulic pusher 121 adjusts the angle of the crossbeam 131 for fine-tuning to fit the subsequent test. Then, the electromagnet 123 works to attract the permanent magnet 124 downward, thereby causing the telescopic support column 125 to be in a retracted state and pressing the spring 122 downward. The sensor records the data at this time. At the same time, the motor 132 controls the screw 133 to rotate, driving the slide block 136, the slider 135 and the suspension device 137 to move along the slide rail to the appropriate position, thereby completing the position and attitude adjustment of the device under test.

[0044] When the experiment is underway, if the stability of the solar panel support 1 is affected by external forces, the force on the spring 122 will change. At this time, the data recorded by the sensor will increase or decrease accordingly. At this time, the value of the current passing through the electromagnet 123 is adjusted to attract or repel the permanent magnet 124, so as to adjust the force on the spring 122 before the height of the telescopic support column 125 changes, and ensure the stability of the crossbeam 131.
