The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0032] The following is combined with Figure 1-4 The utility model is described in further detail.

[0033] Example

[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a satellite fixed-distance micro-propulsion device includes a body 1, a feeding assembly and a conveying assembly.

[0035] The machine body 1 includes a material storage part, a material feeding part and a combustion part.

[0036] In one preferred embodiment of the present invention, the body 1 is a circular columnar structure or a square columnar structure.

[0037] The combustion part comprises a combustion chamber 4 opened in the combustion part, an output port 5 is arranged at one side of the combustion chamber 4, and a conveying channel is arranged at one end of the combustion chamber 4 away from the output port 5.

[0038] Preferably, the combustion chamber 4 is in an elliptical, spherical, cylindrical or other hollow shape, and the coil 3 is embedded in the body 1 and surrounds the combustion chamber 4. This arrangement can make good use of the cavity shape and the pressure of the output port 5 to achieve a greater injection pressure than the stroke, and can transport the vaporized iodine ions to the plasma engine more quickly. In this scheme, the most preferred shapes are elliptical and spherical, because this arrangement can also prevent the iodine ions from remaining on the cavity wall after vaporization.

[0039] The combustion part further includes a coil 3 embedded in the body 1 , and the coil 3 is located outside the combustion chamber 4 .

[0040] The feed portion comprises a feed channel 8 communicating with the conveying channel.

[0041] In this embodiment, if the iodine pressed material is an iodine pressed tablet, the feed channel 8 is a flat sheet-shaped channel that only allows one iodine pressed tablet to pass through.

[0042] In this embodiment, if the iodine pressed object is an iodine pressed ball, the feed channel 8 is a cylindrical channel that only allows one iodine pressed ball to pass through.

[0043] The material storage portion comprises a material storage channel 7 which is perpendicular to the axis of the feeding channel 8 .

[0044] In this embodiment, a number of iodine-based pressurized materials are sequentially arranged and stacked in the storage channel 7. The iodine-based pressurized materials can be used as propellant to achieve the effects of quantitative pushing and quantitative use, thereby achieving the desired fixed-distance micro-pushing effect.

[0045] In this embodiment, the storage channel 7 is a cylindrical open structure, one end of which is connected to the feed channel 8 and the other end is a closed structure, and a loading spring for pushing the iodine pledget is provided in the end of the storage channel 7 away from the feed channel 8.

[0046] In this embodiment, the material storage channel 7 and the material feeding channel 8 are detachably connected.

[0047] In this embodiment, a storage bin 6 is provided at one end of the storage channel 7 away from the feed channel 8, and a plurality of iodine pressed balls can be stored in the storage bin 6. A loading plate is provided on an inner wall of the storage bin 6 away from the storage channel 7. The loading plate and the storage bin 6 are elastically connected, and the pushing pressure of the loading plate is greater than the loading spring, that is, when the loading plate is not pushed to the maximum position, the loading plate is in a tensioned state, and the maximum pushing position of the loading plate is the edge of the storage channel 7.

[0048] The feeding assembly includes a push plate 12 embedded in the feeding channel 8 and a first telescopic motor 11 used for the push plate 12 to extend and retract forward and backward.

[0049] The structure of the push plate 12 matches the structure of the feed channel 8. When the feed channel 8 is a flat plate-shaped cavity, the push plate 12 is a plate-shaped structure. If the feed channel 8 is a cylindrical cavity, the push plate 12 is a cylindrical rod-shaped structure.

[0050] The conveying assembly comprises a piston 10 slidably arranged in a conveying channel and a second telescopic motor used for the piston 10 to slide in the conveying channel.

[0051] A feed port 2 is provided at one end of the conveying channel close to the combustion chamber 4, and the feed port 2 is the connection point between the feed channel 8 and the conveying channel.

[0052] The feed channel 8 is a flat planar structure channel, and the planar structure is coplanar with the axis of the conveying channel.

[0053] The storage channel 7 is perpendicular to the plane of the feed channel 8 and is located on the top surface of the plane.

[0054] A plurality of piston 10 rings are arranged on the side wall of one end of the piston 10 away from the second telescopic motor, and the outer sides of the piston 10 rings are in contact with the conveying channel.

[0055] In this scheme, the plasma engine is not explained too much.

[0056] Working principle: the iodine-based pressed material in the storage channel 7 is pushed by the push plate 12 and slides into the delivery channel. The piston 10 in the delivery channel is driven by the second telescopic motor to push the iodine-based pressed material already in the delivery channel into the combustion chamber 4. Because iodine is easy to sublime, the pressure in the combustion chamber 4 can be increased instantly, thereby evenly outputting iodine ions through the output port 5 to achieve the effect of quantitatively delivering iodine ions.

[0057] It should be noted that all features disclosed in this specification, or steps in all methods or processes disclosed, except for mutually exclusive features and / or steps, can be combined in any manner.

[0058] In addition, the above specific embodiments are exemplary, and those skilled in the art can come up with various solutions inspired by the disclosure of the utility model, and these solutions also belong to the disclosure scope of the utility model and fall within the protection scope of the utility model. Those skilled in the art should understand that the utility model specification and its drawings are illustrative and do not constitute a limitation of the claims.
