Description

Technical Field

[0001] The invention belongs to the technical field of aerospace, and relates to an open tail cover solar wing compression and release mechanism. Background Art

[0002] With the rapid development of my country's space technology, the number of spacecraft launched annually has also increased, and the energy requirements of these spacecraft are also increasing. This inevitably requires large solar panels. Due to the capacity limitations of launch vehicles, these large solar panels must be folded into multiple layers and secured with a compression release mechanism, effectively reducing the size of the spacecraft's solar panels.

[0003] During launch, the launch vehicle rubs against the atmosphere, causing vibrations. If the spacecraft's solar panels are not properly secured, this can have unpredictable adverse effects. Therefore, a certain amount of pre-tensioning is required on the multi-layered, folded solar panels. After the launch vehicle delivers the spacecraft to its designated orbit, the release mechanism releases, allowing the solar panels to unfold to their normal operating position.

[0004] However, the traditional compression and release mechanism cannot achieve a large number of solar wings, and the traditional compression and release mechanism is large in size and can no longer meet the compression and release requirements of multi-layer solar wings. Summary of the Invention

[0005] The technical problem solved by the present invention is: to overcome the shortcomings of the existing technology, propose an open tail cover solar wing compression and release mechanism, provide a compact and efficient compression and release mechanism for multi-layer folding solar wings, and solve the compression and release problem of solar wings of large spacecraft.

[0006] The solution of the present invention is:

[0007] A solar wing compression and release mechanism for an open tail cover includes a compression head cover, a slider, a spring, a screw washer, a compression support sleeve, a spring sleeve, a separation nut, a compression sleeve, a first inner plate of the solar wing, a second inner plate of the solar wing, a third inner plate of the solar wing, a fourth inner plate of the solar wing, an outer plate of the solar wing, a load-bearing bowl, a loading nut, a locking nut, and a compression rod;

[0008] The tightening head sleeve and the tightening support sleeve are connected to the outer plate of the solar wing through screw washers; one end of the bottom end of the spring is sleeved on the spring sleeve, and the fixed end of the spring is connected to the bottom of the slider; the spring sleeve and the tightening support sleeve are fastened by threads; in the tightened state, the separation nut and the tightening rod are threadedly connected, and the load-bearing bowl is pressed on the slider by the loading nut and the locking nut; the tightening sleeve is a hollow cylindrical structure; the tightening sleeve is coaxially arranged above the separation nut; the first inner plate of the solar wing, the second inner plate of the solar wing, the third inner plate of the solar wing, the fourth inner plate of the solar wing, and the outer plate of the solar wing are sequentially sleeved on the outer wall of the tightening sleeve from bottom to top; the load-bearing bowl is sleeved on the outer wall of the tightening rod, and the load-bearing bowl is located at the top of the slider; the loading nut is sleeved on the outer wall of the tightening rod, and is located above the load-bearing bowl; the loading nut is threadedly connected to the tightening rod.

[0009] In the above-mentioned open tail cover solar wing compression and release mechanism, the bottom of the load-bearing bowl is a spherical protrusion structure; the top of the slider is provided with a spherical groove; the bottom of the load-bearing bowl cooperates with the groove on the top of the slider.

[0010] In the above-mentioned open tail cover solar wing compression and release mechanism, the working states of the compression and release mechanism include a compression state and a release state; in the compression state, the compression and release mechanism realizes the compression function of the existing solar wing; in the release state, the compression and release mechanism realizes the release function of the existing solar wing.

[0011] In the above-mentioned open tail cover solar wing compression and release mechanism, in the compression state, the compression rod is a rod-shaped structure placed axially vertically, the bottom end of the compression rod is fastened inside the separation nut, and the upper part of the compression rod presses the load-bearing bowl onto the slider through the loading nut, thereby realizing the compression function of the solar wing.

[0012] In the above-mentioned open tail cover solar wing compression release mechanism, the thread on the separation nut is set as a detonating thread.

[0013] In the above-mentioned open tail cover solar wing compression release mechanism, in the released state, the detonating thread of the separation nut opens, releasing the compression rod, and under the action of the spring, pushes the slider, load-bearing bowl, loading nut, locking nut, and compression rod to move upward; when the slider contacts the compression head cover, it stops moving; the loading nut, locking nut, and compression rod continue to move upward under the action of inertia; when the cone of the compression rod contacts the cone-shaped through hole on the upper part of the spring sleeve, it will be stuck to fix the compression rod.

[0014] In the above-mentioned open tail cover solar wing compression and release mechanism, the lower middle portion of the compression rod is designed as a frustum structure.

[0015] In the above-mentioned open tail cover solar wing compression and release mechanism, the center of the slider is a conical through hole, and a circular groove is provided at the bottom.

[0017] In the above-mentioned open tail cover solar wing compression and release mechanism, the top of the spring sleeve is designed as a truncated cone through hole; when the cone of the compression rod contacts the truncated cone through hole at the top of the spring sleeve, it will be stuck to fix the compression rod.

[0019] (1) In the present invention, when in the compression state, the lower end of the compression rod is fastened inside the separation nut, and the upper part of the compression rod presses the load-bearing bowl tightly onto the slider through the loading nut, thereby realizing the compression function of the solar wing;

[0020] (2) The thread on the separation nut of the present invention is set as a detonating thread. After the separation nut is detonated, the threaded connection between the separation nut and the clamping rod is disconnected, and the clamping rod moves upward under the action of the spring, the slider, the load-bearing bowl and the loading nut; when the slider stops moving after contacting the tight head cover, the clamping rod continues to move upward under the action of inertia; the middle and lower parts of the clamping rod are designed as a frustum structure, and the upper part of the spring sleeve is designed as a frustum-shaped through hole; when the frustum of the clamping rod contacts the frustum-shaped through hole on the upper part of the spring sleeve, they will be stuck to achieve the fixation of the clamping rod, thereby achieving the release of the solar wing;

[0021] (3) The present invention provides an open tail cover solar wing compression and release mechanism, which has the function of occupying a small space and the automatic pop-up and fixation of the compression rod, and can ensure the compression and unfolding of the multi-layer folding solar wing.

[0024] The present invention will be further described below in conjunction with the embodiments.

[0025] In order to solve the compression and release problem of solar wings of large spacecraft, the present invention provides an open tail cover solar wing compression and release mechanism, which provides a compact and efficient compression and release mechanism for multi-layer folding solar wings.

[0026] Open tail cover solar wing compression release mechanism, such as Figure 1As shown, it specifically includes a clamping head cover 1, a slider 2, a spring 3, a screw washer 4, a clamping support sleeve 5, a spring sleeve 6, a separation nut 7, a clamping sleeve 8, a first inner plate 9 of the solar wing, a second inner plate 10 of the solar wing, a third inner plate 11 of the solar wing, a fourth inner plate 12 of the solar wing, an outer plate 13 of the solar wing, a load-bearing bowl 14, a loading nut 15, a locking nut 16 and a clamping rod 17.

[0027] The tightening head cover 1 and the tightening support cover 5 are connected to the solar wing outer panel 13 through screw washers 4; one end of the bottom end of the spring 3 is sleeved on the spring sleeve 6, and the fixed end of the spring 3 is connected to the bottom of the slider 2; the spring sleeve 6 and the tightening support cover 5 are fastened by threads; in the tightened state, the separation nut 7 is threadedly connected to the tightening rod 17, and the load-bearing bowl 14 is pressed onto the slider 2 by the loading nut 15 and the locking nut 16; the tightening sleeve 8 is a hollow cylindrical structure; the tightening sleeve 8 is coaxially arranged above the separation nut 7; the first inner plate 9 of the solar wing, the second inner plate 10 of the solar wing, the third inner plate 11 of the solar wing, the fourth inner plate 12 of the solar wing, and the outer plate 13 of the solar wing are sequentially sleeved on the outer wall of the tightening sleeve 8 from bottom to top; the load-bearing bowl 14 is sleeved on the outer wall of the tightening rod 17, and the load-bearing bowl 14 is located at the top of the slider 2; the loading nut 15 is sleeved on the outer wall of the tightening rod 17, and is located above the load-bearing bowl 14; the loading nut 15 is threadedly connected to the tightening rod 17.

[0028] The bottom of the load-bearing bowl 14 is a spherical protrusion structure; the top of the slider 2 is provided with a spherical groove; the bottom of the load-bearing bowl 14 cooperates with the groove on the top of the slider 2.

[0029] The working state of the compression release mechanism includes the compression state and the release state; in the compression state, the compression release mechanism realizes the compression function of the solar wing, such as Figure 1 In the released state, the pressing release mechanism realizes the release function of the solar wing, as shown in Figure 2 shown.

[0030] In the clamping state, the clamping rod 17 is a rod-shaped structure placed axially vertically. The bottom end of the clamping rod 17 is fastened inside the separation nut 7.

When the slider 2 contacts the compression head cover 1, it stops moving. The loading nut 15, the locking nut 16, and the compression rod 17 continue to move upward due to inertia. When the frustum of the compression rod 17 contacts the frustum-shaped through hole in the upper portion of the spring sleeve 6, it becomes stuck, thereby securing the compression rod 17.

[0033] When installing the spring 3, the top of the spring 3 is inserted into the circular groove at the bottom of the slider 2, and the lower part of the spring 3 is inserted into the outside of the spring sleeve 6. The top of the spring sleeve 6 is designed with a truncated cone-shaped through hole; when the cone of the clamping rod 17 contacts the truncated cone-shaped through hole at the top of the spring sleeve 6, it will be clamped and the clamping rod 17 will be fixed.

[0035] The present invention solves the compression and release problem of solar wings of large spacecraft. The present invention provides an open tail cover solar wing compression and release mechanism, which provides a compact and efficient compression and release mechanism for multi-layer folding solar wings.
