Description

Technical Field

[0001] The utility model relates to the technical field of satellite launch and separation, in particular to a connection and separation device for multi-satellite launch. Background Art

[0002] A satellite is an unmanned spacecraft that orbits the Earth and makes one or more orbits in space. Satellites orbit the Earth according to the laws of celestial mechanics, but their actual motion is very complex due to the influence of the non-spherical Earth's gravitational field, atmospheric drag, the gravitational pull of the Sun, the gravitational pull of the Moon, and light pressure on different orbits. Satellites are the most launched, most widely used, and fastest-growing spacecraft, primarily used in scientific exploration and research, weather forecasting, land resource surveys, land use, regional planning, communications, tracking, navigation, and other fields. During the launch of satellites, a connection and separation device is often required to connect multiple satellites and then separate them in space. However, existing connection and separation devices for multi-satellite launches have some shortcomings, such as:

[0003] Publication No. CN105416615B discloses a microsatellite separation device. The device utilizes a release mechanism to cooperate with a pre-tightening mechanism to control the pre-tightening and locking mechanisms to release the satellite from its securement. However, in actual use, due to the weak signal reception in space, the user may experience difficulty controlling the pre-tightening and locking mechanisms, making it difficult to separate the satellite.

[0004] Therefore, we propose a connection and separation device for multi-satellite launch in order to solve the problems raised above. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] Example 1:

[0033] In order to solve the problem of unstable signal in the prior art that makes it difficult to separate satellites, the following solution is disclosed. Figure 1-6 The utility model provides a technical solution: a connection and separation device for multi-satellite launch, comprising a housing 1, a fixing plate 3 connected to the bottom of the housing 1, the housing 1 having three groups, and the inner side walls of the housing 1 being fitted and connected to each other, and the bottom of the housing 1 being fitted and connected to the fixing plate 3, a limiting rod 5 being provided at the bottom of the fixing plate 3, and the limiting rod 5 passing through the fixing plate 3 and being limitedly connected to the housing 1;

[0034] The top of the fixing plate 3 is provided with two sets of upper and lower satellite fixing mechanisms, and the satellite fixing mechanisms include a signal plate 7 and a device slot 8, and the top of the signal plate 7 is fixedly connected to the device slot 8, and a limiting groove 11 is provided inside the device slot 8, and the limiting groove 11 is fitted with a limiting ring 10 for limiting position, and the outer side of the limiting ring 10 is connected to the satellite body 9, and the satellite body 9 is fixed to the device slot 8; and a rope body 12 and a rope cutter 13 are connected to the top of the signal plate 7, and the rope cutter 13 is located outside the rope body 12, the rope body 12 is fixedly connected to the signal plate 7, and the limiting rod 5 passes through the device slot 8 and the limiting ring 10;

[0035] When using the connection and separation equipment for multi-satellite launch, the shells 1 are first fitted together with the fixing plate 3 to form a cavity. Then, the limiting rod 5 passes through the fixing plate 3 and the shell 1, so that the limiting rod 5 passes through the limiting plate 2 to limit and fix the shell 1. At this time, the limiting rod 5 also passes through the two sets of device grooves 8 and the limiting ring 10, so that the limiting rod 5 limits and fixes the inner side of the device groove 8 and the satellite body 9, thereby fixing the satellite body 9 inside the device groove 8. Then, the shell 1 can be placed inside the rocket.

[0036] The bottom of the fixing plate 3 is connected to the launching base 4, and the bottom of the launching base 4 is connected to the fixing seat 6, and the fixing seat 6 is fixedly connected to the limiting rod 5; the top of the inner side of the shell 1 is provided with a limiting plate 2, and the limiting plates 2 are connected to each other, and the limiting rod 5 passes through the limiting plate 2 to limit and fix it; the top of the shell 1 is connected to the fixing head 15, and the bottom of the fixing head 15 is provided with a card slot, and the top of the limiting rod 5 is connected to the fixing head 15 in a card slot manner;

[0037] The tops of the limit plates 2 are connected to the limit seats 16, and the limit rods 5 pass through the limit seats 16 for limit connection; the tops of a group of device slots 8 at the top of the housing 1 are connected to the pressure plates 14, and the tops of the pressure plates 14 are in contact with the limit plates 2, and the pressure plates 14 are connected to the tops of the rope bodies 12; a filling structure is provided inside the housing 1, and the filling structure is made of no flexible material, and the filling structure squeezes and fixes the outer side of the satellite fixing mechanism;

[0038] When the device needs to be separated from the interior of the rocket, since the limit rod 5 is connected to the launch base 4, the launch base 4 will separate from the shell 1 after pushing the shell 1 back, thereby driving the limit rod 5 to separate from the inside of the shell 1, thereby separating the three groups of shells 1, and also disconnecting the limit groove 11 set inside the device groove 8 from the limit ring 10. At this time, the signal board 7 can be connected through other satellites, or timing can be performed in advance in the signal board 7, so that the signal board 7 controls the rope cutter 13 to cut off the rope body 12, so that the rope body 12 on the outside of the satellite body 9 cannot limit the outside of the satellite body 9, thereby separating the satellite body 9.

[0039] Working principle: When using the connection and separation equipment for multi-satellite launch, the shell 1 is first fitted together with the fixing plate 3 to form a cavity. Then, the limiting rod 5 passes through the fixing plate 3 and the shell 1, so that the limiting rod 5 passes through the limiting plate 2 to limit and fix the shell 1. At this time, the limiting rod 5 also passes through the two sets of device grooves 8 and the limiting ring 10, so that the limiting rod 5 limits and fixes the inner side of the device groove 8 and the satellite body 9, thereby fixing the satellite body 9 inside the device groove 8. Then, the shell 1 is placed inside the rocket.

[0040] When the device needs to be separated from the interior of the rocket, since the limit rod 5 is connected to the launch base 4, the launch base 4 will separate from the shell 1 after pushing the shell 1 back, thereby driving the limit rod 5 to separate from the inside of the shell 1, thereby separating the three groups of shells 1, and also disconnecting the limit groove 11 set inside the device groove 8 from the limit ring 10. At this time, the signal board 7 can be connected through other satellites, or timing can be performed in advance in the signal board 7, so that the signal board 7 controls the rope cutter 13 to cut off the rope body 12, so that the rope body 12 on the outside of the satellite body 9 cannot limit the outside of the satellite body 9, thereby separating the satellite body 9.
