Description

Technical Field

[0001] The present invention relates to the field of locking and releasing technology for space gravitational wave detection, and in particular to a space locking and releasing mechanism for electromagnetically driven unlocking and a working method. Background Art

[0002] Space gravitational wave detection uses similar gravitational wave detection technology to that used on the ground. The light source emits laser light, which is reflected by the surface of the test mass and then received by the receiver. When the gravitational wave passes through the optical path, it causes changes in the light, which in turn produces light interference. The change is received by the receiver, and the existence of gravitational waves can be detected based on the changes in the received information. Since gravitational waves have low frequency and small amplitude and are not easy to monitor, strict requirements are placed on the accuracy of the entire detection system. As the core component of gravitational wave detection, the test mass needs to be released in orbit at an extremely precise position and at an extremely low speed, and be captured by the static electrode plate on the satellite electrode frame and suspended in a predetermined position. This requires improving the release accuracy while ensuring accurate positioning.

[0003] Therefore, it becomes an urgent task to develop a locking and releasing mechanism with low impact, quick response and repeatable ground verification. Summary of the invention

[0045] See also Figures 1 to 9As shown, the present invention provides a space locking and releasing mechanism 1 for electromagnetically driven unlocking, comprising a locking and releasing mechanism 1 and a load compartment bottom plate 2, wherein the locking and releasing mechanism 1 is arranged above the load compartment bottom plate 2; the locking and releasing mechanism 1 comprises a primary locking claw 101, a locking tongue 102, a secondary locking claw 103, a tertiary locking claw 104, a quaternary locking claw 105, a torsion spring 106, an electromagnet 107 and a shell 109, wherein the shell 109 is arranged on the load compartment bottom plate 2, the electromagnet 107 is arranged inside the shell 109, the locking tongue 102 is arranged on the electromagnet 107, the primary locking claw 101, the secondary locking claw 103, the tertiary locking claw 104, the ... The claw 104 and the fourth-level locking claw 105 are both connected to the shell 109, and the fourth-level locking claw 105, the third-level locking claw 104, the second-level locking claw 103, and the first-level locking claw 101 are overlapped in sequence, the locking tongue 102 abuts against the first-level locking claw 101, and the torsion spring 106 is arranged on the hanging holes of the first-level locking claw 101, the second-level locking claw 103, the third-level locking claw 104, and the fourth-level locking claw 105; a locking head 203 and a locking assembly are provided on the load compartment bottom plate 2, one end of the locking head 203 is located in the shell 109, and the locking head 203 is connected to the fourth-level locking claw 105, and the locking assembly is used to lock the load compartment bottom plate 2 and the external device.

[0046] Among them, the load compartment bottom plate 2 is arranged directly below the overall mechanism. When the electromagnetically driven unlocking space locking and releasing mechanism 1 is in the locked state, the locking and releasing mechanism 1 locks the load compartment bottom plate 2; when separated, the electromagnet 107 of the locking and releasing mechanism 1 is energized to adsorb the locking tongue 102, unlock the constraint of the primary locking claw 101, and unlock the load compartment bottom plate 2 by unlocking the locking claw step by step.

[0047] The electromagnetically driven unlocked spatial locking and releasing mechanism 1 has a locking method in which the preload force can be adjusted by the locking assembly. In terms of triggering, it is triggered by the electromagnet 107, which has a quick response, low power consumption, small impact level, no mislocking, and can be repeatedly tested on the ground. In terms of releasing, it can bear a large locking force by releasing the locking claw step by step, while the required unlocking force is very small.

[0048] After the electromagnetically driven unlocked space locking and releasing mechanism 1 is separated, the triggering and actuating elements such as the electromagnet 107, various levels of locking claws, torsion spring 106, etc. that have completed their functions are retained on the platform end, and no waste is generated and the subsequent work of the satellite is not affected.

[0049] In some optional embodiments, the first-level locking claw 101 is provided with a first-level D-shaped surface 110, the second-level locking claw 103 is provided with a second-level D-shaped surface 111, and the third-level locking claw 104 is provided with a third-level D-shaped surface 112. The second-level locking claw 103 is arranged on the first-level D-shaped surface 110, the third-level locking claw 104 is arranged on the second-level D-shaped surface 111, and the fourth-level locking claw 105 is arranged on the third-level D-shaped surface 112.

[0050] By setting the primary D-shaped surface 110, the secondary D-shaped surface 111, and the tertiary D-shaped surface 112, contact surfaces are provided for the secondary locking claw 103, the tertiary locking claw 104, and the quaternary locking claw 105, that is, the locking claws are arranged on the D-shaped surfaces step by step; thereby, the load compartment bottom plate 2 is arranged directly below the overall mechanism. In the locked state, the locking release mechanism 1 locks the load compartment bottom plate 2. When separated, the electromagnet 107 of the locking release mechanism 1 is energized to absorb the locking tongue 102 to unlock the constraint on the primary locking claw 101, and the load compartment bottom plate 2 is unlocked by unlocking the locking claws step by step.

[0051] The four-stage locking claw 105 is provided with a hook head 113 , and the hook head 113 is inserted into the locking head 203 , thereby realizing the connection between the four-stage locking claw 105 and the locking head 203 .

[0052] In some optional embodiments, a baffle 114 is provided at one end of the locking tongue 102 , a stopper 115 is provided on the primary locking claw 101 , the baffle 114 abuts against the stopper 115 , and the baffle 114 is used to limit the axial rotational movement of the primary locking claw 101 .

[0053] By setting the baffle 114 and the block 115, the baffle 114 on the lock tongue 102 abuts against the block 115, thereby preventing the primary lock claw 101 from rotating in the locked state, that is, limiting the axial rotational movement of the primary lock claw 101, and further limiting the secondary lock claw 103, the third lock claw 104, and the fourth lock claw 105.

[0054] In some optional embodiments, both ends of the primary locking claw 101, the secondary locking claw 103, the tertiary locking claw 104, and the quaternary locking claw 105 are provided with knobs 116, and the knobs 116 are inserted into the side wall of the housing 109 and are flush with the outer wall of the housing 109. By setting the knobs 116, the primary locking claw 101, the secondary locking claw 103, the tertiary locking claw 104, and the quaternary locking claw 105 can be adjusted outside the housing 109, so that the primary locking claw 101, the secondary locking claw 103, the tertiary locking claw 104, and the quaternary locking claw 105 are in suitable positions.

[0055] The electromagnetically driven unlocking spatial locking and releasing mechanism 1 further includes a fixing column 117 and a tension spring 118 , wherein the tension spring 118 is connected to the locking tongue 102 , the tension spring 118 is sleeved on the fixing column 117 , and the fixing column 117 is arranged on the housing 109 .

[0056] The connection between the tension spring 118 and the lock tongue 102 can effectively apply a pre-tightening force to the lock tongue 102 to prevent the lock tongue 102 from moving at will. At the same time, the other end of the tension spring 118 is sleeved on the fixing post 117, that is, fixed by the fixing post 117.

[0057] The electromagnetically driven unlocked space locking and releasing mechanism 1 further comprises a bracket 108, wherein the bracket 108 is arranged on the housing 109, and the electromagnet 107 is arranged on the bracket 108. By setting the bracket 108, the electromagnet 107 is fixedly installed, and the installation stability of the electromagnet 107 is ensured.

[0058] In some optional embodiments, the locking assembly includes a disc spring 202 and a loading nut 201 , the disc spring 202 is sleeved on one end of the locking head 203 , and the loading nut 201 is connected to the locking head 203 .

[0059] A disc spring 202 is connected in series between the lock head 203 and the bottom plate 2 of the load compartment to apply a locking force. In the locked state, a torque wrench is used to tighten the bottom loading nut 201 to compress the disc spring 202 to achieve a predetermined locking force value on the lock head 203; when the fourth-level locking claw 105 is unlocked, the constraint on the lock head 203 is released, and the load compartment is released under the action of the ejection assembly (a structure in the external device).

[0060] The load compartment bottom plate 2 is provided with an arc-shaped groove 204, and the lock head 203 is located in the arc-shaped groove 204. That is, the setting of the arc-shaped groove 204 provides an installation position for the lock head 203.

[0061] The present invention also provides a working method of a space locking and releasing mechanism 1 using electromagnetic drive unlocking, comprising:

[0062] In the locked state, the locking tongue 102 baffle 114 in the locking release mechanism 1 limits the axial rotational movement of the primary locking claw 101, the secondary locking claw 103 is built on the primary D-shaped surface 110, the tertiary locking claw 104 is built on the secondary D-shaped surface 111, and the quaternary locking claw 105 is built on the tertiary D-shaped surface 112, which limits its own axial rotational movement, and finally realizes the locking of the quaternary locking claw 105 and the load compartment bottom plate 2, and at this time the torsion spring 106 is in a tightened state;

[0063] During the release process, when the electromagnet 107 is energized and attracted, the lock tongue 102 moves axially, the primary lock claw 101 rotates counterclockwise under the action of the torsion spring 106, the primary D-shaped surface 110 releases the restriction on the secondary lock claw 103, and the secondary lock claw 103 swings clockwise under the action of the torsion spring 106, the secondary D-shaped surface 111 releases the restriction on the tertiary lock claw 104, and the tertiary lock claw 104 swings counterclockwise under the action of the torsion spring 106, the tertiary D-shaped surface 112 contacts the restriction on the fourth lock claw 105, and the fourth lock claw 105 swings clockwise under the action of the torsion spring 106, thereby unlocking the lock head 203, and the load compartment bottom plate 2 moves axially under the action of the ejection assembly to realize the release process of the load compartment.

[0064] After separation is achieved, the triggering and actuating elements including the electromagnet 107, the first-level locking claw 101, the second-level locking claw 103, the third-level locking claw 104, the fourth-level locking claw 105, the torsion spring 106, etc. that have completed their functions are all retained in the locking and releasing device, and no waste is generated and the subsequent work of the satellite is not affected.

[0065] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
