Description

Technical Field

[0001] The present invention relates to the field of aerospace technology, and in particular to a deformation compensator for a non-Newtonian fluid pressure vessel of a spacecraft. Background Art

[0002] Large pressure vessels used in spacecraft are often installed in the form of double flanges. After pressurization, the pressure vessel will produce a certain amount of deformation. When the pressure vessel is installed in the form of double flanges, if both flanges are tightened with bolts, after the pressure vessel is deformed by pressurization, the force generated by the deformation will directly act on the fixture, causing the fixture to deform. The larger the pressure vessel, the greater the deformation after pressurization. Large deformation of the fixture may lead to some catastrophic consequences. If the pressure vessel is repeatedly charged and discharged, it may cause the fixture to deform repeatedly, causing damage to the structure. If used in optically sensitive spacecraft, the deformation caused by charging and discharging pressure will lead to a decrease in observation accuracy, which is also unacceptable.

[0003] Therefore, it is very necessary to develop a pressure vessel compensator suitable for spacecraft to release deformation stress by compensating for the displacement deformation of the flange. Summary of the invention

[0004] In view of the defects in the prior art, an object of the present invention is to provide a deformation compensator for a spacecraft non-Newtonian fluid pressure vessel.

[0005] According to the present invention, a deformation compensator for a non-Newtonian fluid pressure vessel of a spacecraft includes a first compensator component and a second compensator component, wherein a first accommodating space and a second accommodating space are respectively provided inside the first compensator component and the second compensator component, and the first accommodating space and the second accommodating space are both filled with a non-Newtonian fluid;

[0006] The first compensator component and the second compensator component have a separated state and a connected state;

[0007] When the first compensator assembly and the second compensator assembly are in the connected state, a fluid channel is formed between the first accommodating space and the second accommodating space so that the non-Newtonian fluid can flow between the two accommodating spaces through the fluid channel, thereby causing the first compensator assembly and the second compensator assembly to deform externally to adaptively compensate for the deformation and / or stress from the outside;

[0008] When the first compensator assembly and the second compensator assembly are in the separated state, the first accommodating space and the second accommodating space are both in a sealed state.

[0011] Preferably, a first flow channel is provided on the lower wall surface of the first compensator, and the first flow channel is blocked by the first throttling column in a natural state; when an external force drives the first throttling column to move into the first accommodating space, the non-Newtonian fluid can flow out through the first flow channel.

The second bellows, the second compensator upper wall, and the second compensator lower wall together form the second accommodating space, and the second plug is arranged on the second compensator lower wall.

[0015] Preferably, the second bellows has a second flow channel, the second throttling column penetrates the second flow channel, and the second flow channel is blocked by the second throttling column in a natural state; when an external force drives the second throttling column to move into the second accommodating space, the non-Newtonian fluid can flow out through the second flow channel.

[0016] Preferably, the upper wall surface of the second compensator has an internal threaded hole, and the end of the lower wall surface of the first compensator has an external threaded protrusion matching the internal threaded hole.

[0018] The non-Newtonian fluid is sealed in the compensator assembly and the free flow of the non-Newtonian fluid is achieved through the fluid channel formed by connecting the first compensator assembly and the second compensator assembly. When the first compensator assembly is separated from the second compensator assembly, the throttling column inside the compensator assembly can still achieve fluid sealing. It is suitable for use in the vacuum environment of space. The non-Newtonian fluid in the compensator assembly is rigid when deformed rapidly and is used to support the flange of the pressure vessel.

[0064] The present invention is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those of ordinary skill in the art, several changes and improvements can also be made without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0065] The present invention provides a deformation compensator for a non-Newtonian fluid pressure vessel of a spacecraft, comprising a first compensator component 1 and a second compensator component 2. The first compensator component 1 and the second compensator component 2 are respectively provided with a first accommodating space and a second accommodating space. The first accommodating space and the second accommodating space are both filled with a non-Newtonian fluid 12. The first compensator component 1 and the second compensator component 2 are airtight and can seal the non-Newtonian fluid 12 inside the components to prevent leakage into a vacuum environment.

[0066] Specifically, the first compensator component 1 and the second compensator component 2 have a separation state and a connection state; when the first compensator component 1 and the second compensator component 2 are in the connection state, Figure 1 , Figure 6 As shown, a fluid channel 101 is formed between the first accommodation space and the second accommodation space, so that the non-Newtonian fluid 12 can flow between the two accommodation spaces through the fluid channel 101. Figure 8 As shown, the first compensator assembly 1 and the second compensator assembly 2 are deformed externally to adaptively compensate for the external deformation and / or stress. When the first compensator assembly 1 and the second compensator assembly 2 are in a separated state, as shown in FIG. Figure 2 , Figure 3 As shown, the first accommodating space and the second accommodating space are both in a sealed state.

[0067] like Figure 3 As shown, the first compensator assembly 1 includes a first compensator body 3, a first plug 5, a first spring 7 and a first throttle column 9. The first plug 5 is detachably configured at one end of the first compensator body 3, the first throttle column 9 is arranged inside the first compensator body 3 and located at the other end of the first compensator body 3, and the first spring 7 is arranged between the first plug 5 and the first throttle column 9 and is in a compressed state. Therefore, under the action of the elastic restoring force of the first spring 7, the first throttle column 9 can be squeezed and abutted against the inner wall of the first compensator body 3.

[0068] Furthermore, if Figure 4As shown, the first compensator body 3 includes a first bellows 31, a first compensator upper wall 32 arranged at one end of the first bellows 31, and a first compensator lower wall 33 arranged at the other end of the first bellows 31. The first bellows 31, the first compensator upper wall 32, and the first compensator lower wall 33 are all made of stainless steel and welded together to form a first accommodating space. The first bellows 31 has a telescopic function; the first plug 5 is arranged on the first compensator upper wall 32. The first plug 5 is preferably screwed on the first compensator upper wall 32 by threads. When the first plug 5 is loosened and removed from the first compensator upper wall 32, the first spring 7 and the first throttle column 9 can be taken out from the inside of the first compensator body 3.

[0069] Specifically, the first compensator has a first flow channel 34 on the lower wall surface 33, and the cross section of the first throttling column 9 is a T-shaped structure, including a column and a cylindrical platform arranged at the bottom of the column. The column and the cylindrical platform are integrally formed. A plurality of flow channel holes 91 are arranged circumferentially on the cylindrical platform. The flow channel holes 91 can be used as a channel connecting the first accommodating space and the first flow channel 34. The first throttling column 9 with flow channel holes 91 of different apertures can be replaced as needed to adjust the flow resistance, such as Figure 7 shown.

[0070] Furthermore, a first annular groove is arranged on the end face of the cylindrical table, and a first O-ring 11 is arranged in the first annular groove. A part of the first O-ring 11 is located in the first annular groove, and the other part protrudes to the outside of the first annular groove. In a natural state, the first throttling column 9 is squeezed by the first spring 7 so that the first throttling column 9 and the lower wall surface 33 of the first compensator are squeezed tightly. At this time, the first O-ring 11 plays a role of sealing between the first throttling column 9 and the lower wall surface 33 of the first compensator, and the first flow channel 34 is blocked by the first throttling column 9; when an external force drives the first throttling column 9 to move into the first accommodating space, the first throttling column 9 drives the first O-ring 11 to leave the lower wall surface 33 of the first compensator. At this time, the non-Newtonian fluid 12 in the first accommodating space can flow out through the first flow channel 34.

[0071] like Figure 2 , Figure 3 , Figure 5As shown, the second compensator assembly 2 includes a second compensator body 4, a second plug 6, a second spring 8 and a second throttle column 10. The second plug 6 is detachably arranged at one end of the second compensator body 4. Preferably, the second plug 6 is screwed on the second compensator body 4 by threaded fitting. A portion of the second throttle column 10 is arranged inside the second compensator body 4, and another portion of the second throttle column 10 extends toward the other end of the second compensator body 4. The second spring 8 is arranged between the second plug 6 and the second throttle column 10 and is in a compressed state, so that the second throttle column 10 is always tightened. It should be noted that the second spring 8 and the second throttle column 10 can be removed from the inside of the second compensator body 4 by removing the second plug 6.

[0072] Furthermore, the second compensator body 4 includes a second bellows 41, a second compensator upper wall 42 arranged at one end of the second bellows 41, and a second compensator lower wall 43 arranged at the other end of the second bellows 41. The second bellows 41, the second compensator upper wall 42, and the second compensator lower wall 43 together form a second accommodating space, and the second plug 6 is arranged on the second compensator lower wall 43. The second bellows 41 is provided with a second flow channel 44, and the second throttling column 10 runs through the second flow channel 44. The cross-section of the second throttling column 10 is a cross-shaped structure, and the root of the other part of the second throttling column 10 is circumferentially provided with a second annular groove, and a second O-ring 13 is arranged in the second annular groove. In a natural state, due to the elastic restoring force of the second spring 8, the second throttling column 10 drives the second O-ring 13 to abut against the upper wall 42 of the second compensator, so that the second flow channel 44 is blocked by the second throttling column 10; when an external force drives the second throttling column 10 to move into the second accommodating space, the second throttling column 10 drives the second O-ring 13 to leave the upper wall 42 of the second compensator. At this time, the non-Newtonian fluid 12 can flow out through the second flow channel 44.

[0073] like Figure 3 , Figure 6 As shown, the second compensator upper wall 42 has an internal threaded hole, and the end of the first compensator lower wall 33 has an external threaded protrusion matching the internal threaded hole. When the external threaded protrusion is assembled into the internal threaded hole, the first compensator assembly 1 and the second compensator assembly 2 are in a connected state. At this time, the other part of the second throttling column 10 passes through the first flow channel 34 and abuts against the first throttling column 9, so that the first throttling column 9 moves a distance toward the first accommodating space, thereby causing the first throttling column 9 to drive the first O-ring 11 to leave the first compensator lower wall 33. At the same time, since the second throttling column 10 is subjected to the reaction force of the first throttling column 9, the second throttling column 10 also drives the second O-ring 13 to leave the second compensator upper wall 42 for a distance, thereby connecting the first flow channel 34 to the second flow channel 44, and the first accommodating space is connected to the second accommodating space.

[0074] like Figure 6 As shown, the bottom of the internal threaded hole or the bottom of the external threaded protrusion has a seal, and the seal is preferably a third O-ring 421. When the external threaded protrusion is assembled into the internal threaded hole, the end of the external threaded protrusion or the bottom of the internal threaded hole is squeezed with the seal to form a sealed connection, thereby preventing the non-Newtonian fluid 12 from flowing to the outside of the compensator through the gap between the external threaded protrusion and the internal threaded hole when passing through the fluid channel 101.

[0075] It should be noted that in order to increase the firmness of the compensator component, the first O-ring 11, the second O-ring 13 and the third sealing ring 421 are all embedded in the wall surface to prevent the O-rings from falling off when the compensator assembly moves.

[0076] The present invention seals the non-Newtonian fluid 12 inside the compensator assembly, and realizes the free flow of the non-Newtonian fluid 12 through the fluid channel 101 formed by connecting the first compensator assembly 1 and the second compensator assembly 2. The end of the external thread protrusion or the bottom of the internal thread hole is squeezed with the seal to form a sealed connection to prevent the fluid from volatilizing. At the same time, the second throttling column 10 will lift the first throttling column 9 to form a Figure 8 The fluid channel 101 shown can connect the non-Newtonian fluid 12 inside the first compensator assembly 1 and the second compensator assembly 2. When the first compensator assembly 1 is separated from the second compensator assembly 2, the two compensator assemblies lift the throttling column through their respective springs, and the O-ring on the throttling column will form a seal with the compensator body to ensure that the internal fluid will not evaporate into the vacuum environment, which is suitable for use in the vacuum environment of space. The non-Newtonian fluid 12 in the compensator assembly is rigid when deformed rapidly, and is used to support the mounting flange 20 of the pressure vessel, while the slow deformation caused by the pressure vessel filling and releasing pressure can flow through the non-Newtonian fluid 12 in the compensator assembly, cooperate with the deformation of the pressure vessel mounting flange 20, and release the deformation stress of the pressure vessel.

[0077] In one possible embodiment, Figure 6 As shown, the fixing device 30 is on the aircraft, and the first compensator component 1 passes through the mounting flange 20 and is connected to the second compensator component 2 through threads to realize the deformation compensation function.

[0079] The above describes the specific embodiments of the present invention.
