Description

Technical Field

[0001] The utility model relates to the technical field of iodine working medium electric propulsion storage and supply, in particular to an iodine working medium electric propulsion storage and supply system. Background Art

[0002] With the advancement of the times, new spacecraft platforms have been rapidly developed. One of the key factors in spacecraft platforms is a well-matched propulsion system to perform various tasks, such as orbital changes. With the development of propulsion technology, electric propulsion technology has obvious advantages in high specific impulse and mass volume. Electric propulsion uses the ionization of the working fluid to generate ion or plasma jets to generate reverse thrust. Xenon, as a traditional electric propulsion working fluid, has good performance and can meet the needs of most space missions. However, xenon reserves in nature are small and difficult to extract, resulting in its high price, which is not conducive to the large-scale application of xenon working fluid electric propulsion systems. Solid iodine has the advantages of low price, high storage density, and low-pressure storage, making solid iodine a propellant for electric propulsion systems with great potential.

[0003] Patent number CN116591862A is an integrated storage and supply device for solid iodine working fluid. An integrated storage tank body is provided, and two or more small storage tanks are provided inside the integrated storage tank body. Solid iodine working fluid is stored inside each small storage tank. A heating component for heating the small storage tank is provided outside each small storage tank. An outlet is provided on each small storage tank. The outlet of each small storage tank is connected to the inlet end of the main pipeline through a corresponding branch pipeline. A main valve is provided on the main pipeline, and the outlet end of the main pipeline is connected to the thruster.

[0004] However, research has shown that the existing iodine working fluid electric propulsion storage and supply system still has the following defects:

[0005] Existing thrusters and storage tanks need to be connected by pipes, and generally the thrusters, storage tanks and pipes are connected by flanges. However, iodine vapor is corrosive and will corrode the sealing gaskets on the flanges. If the corrosion time is long, the sealing gaskets will be damaged, causing the sealing of the connection to deteriorate, leading to iodine vapor leakage. Therefore, it is necessary to optimize an iodine working fluid electric propulsion storage and supply system through technological innovation and design optimization. Utility Model Content

[0006] The existing thrusters and storage boxes need to be connected by pipelines, and the thrusters, storage boxes and pipelines are generally connected by flanges. However, iodine vapor is corrosive and will corrode the sealing gasket on the flange. If the corrosion time is long, the sealing gasket will be damaged, which will cause the sealing of the connection to deteriorate, resulting in iodine vapor leakage. In order to solve the above problems, an embodiment of the present application provides an iodine working medium electric propulsion storage and supply system. By inserting the main ceramic ring into the slot inside the secondary ceramic ring, the magnetic ring one and the magnetic ring two attract each other, and the main ceramic ring and the secondary ceramic ring fit tightly, avoiding direct contact between the iodine vapor and the sealing gasket, thereby improving the service life of the sealing gasket. At the same time, by setting a conical ceramic cylinder, the iodine vapor can directly enter the interior of the pipeline, avoiding direct impact of iodine vapor on the joint between the main ceramic ring and the secondary ceramic ring, thereby improving the sealing of the main ceramic ring and the secondary ceramic ring.

[0007] The technical solution adopted by the embodiment of the present application to solve the technical problem is:

[0008] An iodine working medium electric propulsion storage and supply system, comprising:

[0009] A storage box, wherein a propeller is provided on one side of the storage box;

[0010] a pipeline, the pipeline being located between the storage tank and the propeller, the propeller and the pipeline being connected as well as the storage tank and the pipeline via a connecting mechanism;

[0011] The anti-corrosion mechanism is located inside the connecting mechanism and can prevent the connecting mechanism from corrosion.

[0012] In one possible implementation, a heating tube is wrapped around the pipe, and the heating tube is in close contact with the outer wall of the pipe. The heating tube can heat the pipe to prevent the iodine vapor from solidifying when it is cold, so that the iodine vapor remains in a gaseous state. The inside of the pipe is coated with an anti-corrosion coating to prevent the iodine vapor from corroding the inner wall of the pipe.

[0013] In one possible implementation, the connecting mechanism includes secondary connecting cylinders fixed at both ends of the pipeline, a main connecting cylinder is fixed to the storage box and the thruster on the side facing the pipeline, a main fixing plate is fixed on the main connecting cylinder, a secondary fixing plate is fixed on the secondary connecting cylinder, bolts and nuts are provided on the main fixing plate and the secondary fixing plate, sealing gaskets are fixed on one side of the main connecting cylinder and the secondary connecting cylinder, the main fixing plate and the secondary fixing plate can be fixed by bolts and nuts, thereby completing the fixation of the main connecting cylinder and the secondary connecting cylinder, thereby completing the connection between the thruster, the storage box and the pipeline.

[0014] In a possible implementation, circular holes are formed on both the main fixing plate and the secondary fixing plate, the bolts pass through the circular holes, and the nuts are threadedly connected to the bolts, so as to facilitate fixing the main fixing plate and the secondary fixing plate.

[0015] In one possible implementation, the anti-corrosion mechanism includes a main ceramic ring fixed inside the main connecting tube, a secondary ceramic ring fixed inside the secondary connecting tube, a slot provided on the side of the secondary ceramic ring facing the main ceramic ring, and the main ceramic ring can be inserted into the secondary ceramic ring. When the main ceramic ring is inserted into the slot inside the secondary ceramic ring, direct contact between iodine vapor and the sealing gasket and corrosion of the sealing gasket will be avoided. At the same time, both the main ceramic ring and the secondary ceramic ring are made of ceramic, have good stability, and will not be corroded by iodine vapor.

[0016] In one possible implementation, an annular groove is provided on the side of the primary ceramic ring facing the secondary ceramic ring, a magnetic ring 1 is fixed inside the annular groove, and a magnetic ring 2 is fixed inside the slot, and the magnetic ring 2 can be inserted into the annular groove to facilitate a close fit between the primary ceramic ring and the secondary ceramic ring.

[0017] In one possible implementation, the magnetic poles of the facing surfaces of the magnetic ring 1 and the magnetic ring 2 are opposite, and the magnetic ring 1 and the magnetic ring 2 can attract each other. The magnetic ring 1 and the magnetic ring 2 are both made of aluminum nickel cobalt magnets, which are relatively stable and will not be corroded by iodine vapor.

[0018] In one possible implementation, a conical ceramic cylinder is fixed inside the main connecting cylinder. The diameter of the conical ceramic cylinder close to the end of the pipe is smaller than the diameter of the end away from the pipe, which is convenient for guiding the iodine vapor and preventing the iodine vapor from staying inside the connecting mechanism. It can also prevent the iodine vapor from directly impacting the joint between the main ceramic ring and the secondary ceramic ring, thereby improving the sealing performance of the main ceramic ring and the secondary ceramic ring.

[0019] In summary, the present invention has at least one of the following beneficial technical effects:

[0020] 1. By inserting the main ceramic ring into the slot inside the secondary ceramic ring, the magnetic ring 1 and the magnetic ring 2 attract each other, and the main ceramic ring and the secondary ceramic ring fit tightly together, avoiding direct contact of iodine vapor with the sealing gasket, thereby increasing the service life of the sealing gasket;

[0021] 2. By setting up a conical ceramic cylinder, the iodine vapor can directly enter the interior of the pipe, preventing the iodine vapor from directly impacting the joint between the primary ceramic ring and the secondary ceramic ring, thereby improving the sealing performance of the primary ceramic ring and the secondary ceramic ring.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the present invention to clearly and completely describe the technical solution of the present invention. In addition, the forms of the various structures described in the following embodiments are merely examples. The instrument placement rack involved in the present invention is not limited to the various structures described in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0029] This embodiment introduces the specific structure of an iodine working medium electric propulsion storage and supply system. Figure 1-Figure 5 As shown, an iodine working medium electric propulsion storage and supply system comprises:

[0030] A storage box 5, with a propeller 1 provided on one side of the storage box 5;

[0031] Pipeline 3, pipeline 3 is located between the storage box 5 and the propeller 1, and the propeller 1 and pipeline 3, as well as the storage box 5 and pipeline 3, are connected via a connecting mechanism;

[0032] The anti-corrosion mechanism is located inside the connecting mechanism and can prevent corrosion of the connecting mechanism.

[0033] It is worth noting that a heating tube 2 is wrapped around the pipe 3, and the heating tube 2 is close to the outer wall of the pipe 3. The heating tube 2 can heat the pipe 3 to prevent the iodine vapor from solidifying when it is cold, so that the iodine vapor remains in a gaseous state. The inside of the pipe 3 is coated with an anti-corrosion coating to prevent the iodine vapor from corroding the inner wall of the pipe 3.

[0034] Furthermore, the connecting mechanism includes a secondary connecting tube 6 fixed at both ends of the pipeline 3, a main connecting tube 4 is fixed on the side of the storage box 5 and the thruster 1 facing the pipeline 3, a main fixing plate 8 is fixed on the main connecting tube 4, and a secondary fixing plate 7 is fixed on the secondary connecting tube 6. The main fixing plate 8 and the secondary fixing plate are provided with bolts 12 and nuts 11, and the main connecting tube 4 and the secondary connecting tube 6 are fixed with sealing gaskets near one side. The main fixing plate 8 and the secondary fixing plate 7 can be fixed by the bolts 12 and nuts 11, thereby completing the fixation of the main connecting tube 4 and the secondary connecting tube 6, thereby completing the connection between the thruster 1, the storage box 5 and the pipeline 3.

[0035] In addition, circular holes are provided on the main fixing plate 8 and the secondary fixing plate 7 , and bolts 12 pass through the circular holes. Nuts 11 are threadedly connected to the bolts 12 , which facilitates fixing the main fixing plate 8 and the secondary fixing plate 7 .

[0036] Since the thruster 1 and the storage tank 5 need to be connected through a pipe 3, the thruster 1, the storage tank 5 and the pipe 3 are generally connected through a flange. However, iodine vapor is corrosive and will corrode the sealing gasket on the flange. If the corrosion time is long, the sealing gasket will be damaged, which will cause the sealing of the connection to deteriorate, resulting in iodine vapor leakage.

[0037] The anti-corrosion mechanism includes a primary ceramic ring 9 fixed inside the primary connecting tube 4, a secondary ceramic ring 13 fixed inside the secondary connecting tube 6, and a slot 14 provided on the side of the secondary ceramic ring 13 facing the primary ceramic ring 9. The primary ceramic ring 9 can be inserted into the secondary ceramic ring 13. When the primary ceramic ring 9 is inserted into the slot 14 inside the secondary ceramic ring 13, it prevents iodine vapor from directly contacting the sealing gasket and causing corrosion to the sealing gasket. At the same time, the primary ceramic ring 9 and the secondary ceramic ring 13 are both made of ceramic, have good stability, and are not corroded by iodine vapor. The primary ceramic ring 9 has an annular groove 16 on the side facing the secondary ceramic ring 13. A magnetic ring 15 is fixed inside the annular groove 16, and a magnetic ring 2 is fixed inside the slot 14. The magnetic ring 2 17 can be inserted into the annular groove 16 to facilitate a close fit between the primary ceramic ring 9 and the secondary ceramic ring 13. The magnetic poles of the facing surfaces of the magnetic ring 15 and the magnetic ring 2 17 are opposite, and the magnetic ring 15 and the magnetic ring 2 17 can attract each other. The magnetic ring 15 and the magnetic ring 2 17 are both made of aluminum nickel cobalt magnets, which are relatively stable and will not be corroded by iodine vapor.

[0038] It is worth noting that a conical ceramic tube 10 is fixed inside the main connecting tube 4. The diameter of the conical ceramic tube 10 close to the end of the pipe 3 is smaller than the diameter of the end away from the pipe 3, which is convenient for guiding the iodine vapor and preventing the iodine vapor from staying inside the connecting mechanism. At the same time, it can also prevent the iodine vapor from directly impacting the joint between the main ceramic ring 9 and the secondary ceramic ring 13, thereby improving the sealing performance of the main ceramic ring 9 and the secondary ceramic ring 13.

[0039] When the staff needs to connect the thruster 1, the storage box 5 and the pipeline 3, the main connecting tube 4 is aligned with the secondary connecting tube 6. At this time, the main ceramic tube will be aligned with the secondary ceramic tube, and the main ceramic ring 9 is inserted into the slot 14 inside the secondary ceramic ring 13. The magnetic ring 15 and the magnetic ring 2 17 attract each other, and the main ceramic ring 9 fits tightly with the secondary ceramic ring 13. Then the main connecting tube 4 and the secondary connecting tube 6 are fixed by bolts 12. When iodine vapor passes through the connecting mechanism, it will directly enter the inside of the pipeline 3 due to the conical ceramic tube 10. A small amount of iodine vapor will be blocked by the main ceramic ring 9 and the secondary ceramic ring 13, avoiding direct contact between iodine vapor and the sealing gasket, thereby improving the service life of the sealing gasket.

[0040] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all possible embodiments. However, any obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
