[0024] The utility model can be implemented by those skilled in the art without some of the specific details. The following description of the embodiments is merely to provide a better understanding of the utility model by showing examples of the utility model.

[0025] Referring to Figure 1 The utility model provides a kind of rope anti-hooking device for deployment mechanism at least includes: fixed support 1, mobile support 2, central support 3 and rope winding drum 4.Fixed support 1 is used to set on the fixed component of deployment mechanism, mobile support 2 is used to set on the moving component of deployment mechanism, central support 3 is set between fixed support 1 and mobile support 2.Rope winding drum 4 is set on the top of central support 3, is equipped with the channel for winding and releasing rope 5.Rope 5 first end is connected with fixed support 1, second end is connected with mobile support 2, and the rope between both ends is wound in rope winding drum 4.In the process that the deployment mechanism of satellite changes from winding state to deployment state, mobile support 2 moves along the deployment direction (direction away from fixed support 1) with moving component, and pulls rope 5 and orderly pulls it out from rope winding drum 4.Rope 5 is always approximately tensioned during deployment release process, and will not float randomly, and after mechanism deployment is in place, the mobile support of far end stops movement, and rope 5 reaches tensioned state.Rope winding drum 4 of this embodiment not only has the effect of accommodation, but also has the effect of certain tensioning rope.With the pulling out of rope, rope winding drum 4 can keep rope in tensioned state at any time, to effectively avoid that rope is hooked by the edge of satellite deployment plate.

[0026] Among them, rope winding drum 4 has two outlets, first outlet is set towards fixed support 1, and second outlet is set towards mobile support 2.Rope 5 can be pulled out along first outlet or second outlet alone, or can be pulled out along first outlet and second outlet simultaneously.

[0027] The rope anti-hooking device of the utility model embodiment is applied to the deployment mechanism of satellite, wherein fixed support is fixedly arranged on the non-deployment part (fixed component) of deployment mechanism, and the position of fixed support does not change in the deployment process of deployment mechanism.Mobile support is fixedly arranged on the deployment part (moving component) of deployment mechanism, and mobile support moves with deployment part in the deployment process of deployment mechanism.Central support can be arranged on the non-deployment part (fixed component) of deployment mechanism, or can be arranged on the deployment part (moving component).

[0028] Referring to Figure 1 And Figure 2For example, the central support 3 is arranged on the fixed assembly close to the fixed support 1. In the present embodiment, the positions of the central support 3 and the fixed support 1 do not change during the deployment release of the satellite deployment mechanism, and the distance between the two is constant. At this time, the ropes are orderly released along the winding drum 4 towards the opening (second outlet) on the side of the moving support 2 until the deployment mechanism is deployed in place and tensioned (as shown in Figure 2

[0029] Alternatively, in one embodiment, the central support is arranged on the moving assembly close to the moving support. With the deployment release of the deployment mechanism, the central support 3 moves correspondingly with the moving assembly. During this process, the distance between the moving support 2 and the central support 3 can remain unchanged or can change. Specifically, the moving assembly can be divided into different deployment plates, and the deployment degrees of the deployment plates are not completely the same. If the moving support 2 and the central support 3 are arranged on different deployment plates, the distance between the two changes during the deployment of the deployment mechanism. If the moving support 2 and the central support 3 are arranged on the same deployment plate, the distance between the two remains unchanged during the deployment of the deployment mechanism.

[0030] Therefore, after the winding drum 4 winds up the middle part of the rope 5, the winding drum 4 is arranged such that the ropes can be released from both the first outlet and the second outlet.

[0031] In one embodiment, in order to avoid the ropes from being released from the winding drum too early, a plurality of grooves can be arranged in the winding drum, and the ropes are wound in the form of a slip knot in each groove. In this way, the ropes are always constrained by the slip knot before the deployment mechanism is deployed, and the slip knot of the ropes is orderly opened after the deployment mechanism starts to deploy, so that the ropes are orderly released under a certain tension, avoiding the randomness and uncertainty of the position of the ropes and eliminating the risk of mutual hooking.

[0032] In the above embodiments, in order to further avoid the risk of hooking of the ropes, the fixed support, the central support and the moving support can be arranged coaxially and collinearly. In this way, the control of the deployment stiffness and the array accuracy of the mechanism can also be achieved, and the deployment reliability is improved.

[0033] In any of the above embodiments, if the size of the deployed mechanism is large after deployment, resulting in a long length of the ropes required, it is difficult to wind up the long ropes in one winding drum. In this case, a plurality of winding drums can be connected in series to wind up the ropes one by one. Specifically, a plurality of central supports can be arranged between the fixed support and the moving support, and a winding drum is installed on the top of each central support. In this way, the part between the two ends of the rope can be wound up in the winding drums one by one, solving the problem of winding and arranging the ropes when the large deployment mechanism is tensioned.

[0034] Referring to Figure 1 and Figure 2 ​The connecting mode of the rope and the fixed support and the rope and the movable support can be freely selected, and is stable and reliable. For example, the fixed support 1 is arranged at the fixed assembly of the satellite unfolding mechanism, the top of the fixed support 1 is provided with a first mounting hole through which the rope 5 passes, and the first end of the rope 5 is connected to the fixed support 1 through a clamp 6 after passing through the first mounting hole. The movable support 2 is arranged at the movable assembly of the satellite unfolding mechanism, the top of the movable support 2 is provided with a second mounting hole through which the rope 5 passes, and the second end of the rope 5 is connected to the movable support 2 through a clamp 7 after passing through the second mounting hole.

[0035] Specifically, the fixed support and the movable support can be installed on the satellite unfolding mechanism through bolts, and after the length of the rope required according to the size of the satellite unfolding mechanism is determined, the two ends of the rope are fixed to the fixed support and the movable support through clamps, so that the rope is axially limited in the tensioned state.

[0036] In the above embodiment, the first mounting hole and the second mounting hole are coaxially and collinearly arranged.

[0037] The above embodiments can be combined with each other, and have corresponding technical effects.

[0038] The utility model discloses another aspect provides a satellite unfolding mechanism, and the satellite unfolding mechanism at least includes the rope anti-hooking device in any one embodiment.

[0039] The rope anti-hooking device for the unfolding mechanism and the satellite unfolding mechanism solve the storage and arrangement problem of the large unfolding mechanism when the rope is tensioned and retracted, and also realize the orderly release of the rope in the approximate tensioned state, completely avoiding the risk of rope hooking.

[0040] The above is only a preferred embodiment of the utility model, and does not limit the utility model, and any modification, equivalent replacement, improvement, etc. within the spirit and principle of the utility model should be included in the protection scope of the utility model.
