Description

Technical Field

[0001] This invention relates to the field of extraterrestrial landing sampler technology, and in particular to a primary packaging device for wide positioning error mitigation for collecting samples from the surface of extraterrestrial bodies. Background Technology

[0002] The surface of extraterrestrial bodies is covered with weathering layers of different grain sizes, formed by the impact of countless meteorites, the physical disintegration of rocks, and radiation damage. After hundreds of millions of years of light radiation, these layers contain volatile chemical elements and isotopes emitted by light radiation. The study of soil samples from these bodies is of great scientific significance for exploring the formation and evolution of the universe and revealing the origin and evolution of life.

[0003] The primary sealing device is a crucial component of an extraterrestrial lander sampler, used for collecting and initially sealing surface samples from celestial bodies. Due to the unique environment of extraterrestrial bodies and the small particle diameter of the surface samples, these collected soil samples tend to float and adhere to mechanical equipment, making it difficult for them to settle at the bottom of the sampling container, often resulting in a high leakage rate during collection. Furthermore, after sampling, the sampling container needs to be preliminarily and automatically sealed; the sealing action should be simple and reliable.

[0004] However, there are few methods for sampling and encapsulating samples from extraterrestrial surfaces, and even fewer primary encapsulation devices are used for this purpose. Existing encapsulation containers are not designed to reduce leakage rates, and the primary encapsulation process is quite complex.

[0005] Based on the need for extraterrestrial object sampling, there is an urgent need to invent a sample collection device with a wide positioning error range and simple encapsulation operation. Summary of the Invention

[0006] The purpose of this invention is to provide a primary packaging device for wide positioning error mitigation for collecting samples from the surface of extraterrestrial objects, in order to solve the problems existing in the prior art.

[0007] The technical solution adopted to achieve the purpose of this invention is as follows: a primary packaging device for wide positioning error mitigation for collecting samples from the surface of extraterrestrial objects, comprising a primary sealing container, a bottom excitation assembly, an axial drive assembly, a swing drive assembly, a track plate, and a funnel assembly.

[0008] The initial sealing container includes a top seal, a container body, and a top seal valve. The container body has a barrel structure. A bottom vibration assembly is located at the bottom of the container body. The top seal is located at the open top of the container body. The top seal is generally a circular plate. A pouring outlet is provided on the surface of the circular plate. A top seal pin and a limiting part are protruding on the lower surface of the top seal. The top seal valve is generally an arc-shaped plate. A pin hole is provided on the surface of the top seal valve. A wedge foot is provided on the upper surface of the top seal valve.

[0009] A top sealing valve is positioned below the top seal of the container. The top sealing pin is inserted into a pin hole. A valve torsion spring is also fitted onto the top sealing pin. The valve torsion spring includes a first torsion arm and a second torsion arm. A first groove for engaging the first torsion arm is provided on the side wall of the top sealing pin. A second groove for engaging the second torsion arm is provided on the wall of the pin hole. Under the force of the valve torsion spring, the wedge abuts against the limiting part, and the top sealing valve seals the pouring outlet.

[0010] The swing drive assembly includes a swing plate, a swing drive torsion spring, a swing shaft seat, a connecting part, and a rotating shaft. The swing shaft seat is detachably mounted on the lander sampler. Two parallel clamping plates are provided on the lower surface of the swing plate. The rotating shaft passes through the two clamping plates and the swing shaft seat, rotatably mounting the swing plate onto the swing shaft seat. The swing drive torsion spring is sleeved on the rotating shaft. The two clamping plates clamp and limit the swing drive torsion spring. One torsion arm of the swing drive torsion spring is engaged with the swing shaft seat, and the other end is attached to the lower surface of the swing plate. The connecting part includes a cylindrical outer shell and two anti-rotation arm connecting protrusions provided on the outer wall of the cylindrical outer shell. The connecting part is located on the upper surface of the swing plate. The axial drive assembly is a linear motion mechanism. The axial drive assembly is located within the inner cavity of the cylindrical outer shell.

[0011] The track plate is detachably mounted on the landing sampler. The track plate has track grooves. The track lines of the track grooves include an elevation section, a deflection section, and a termination section. The elevation section is a vertical straight groove. The deflection section is an arc groove. The termination section is a horizontal straight groove. The elevation section, deflection section, and termination section are smoothly connected sequentially.

[0012] The funnel assembly includes a funnel body, a funnel support column, a funnel anti-rotation arm, a funnel vibration motor, and a connecting bearing. In the initial state, the lower end of the funnel body extends into the pouring outlet. The upper end of the funnel support column is fixed to the side wall of the funnel, and the lower end extends into the cylindrical outer shell. The lower surface of the funnel support column abuts against the upper surface of the axial drive assembly. The funnel anti-rotation arm includes two parallel folding arms. Each folding arm includes a first connecting rod and a second connecting rod. The first end of the first connecting rod is hinged to the side wall of the funnel body, and its tail end is rotatably connected to the first end of the second connecting rod. The tail end of the second connecting rod is rotatably connected to a connecting protrusion on the anti-rotation arm. One end of the connecting bearing is fixed to the side wall of the funnel, and the other end is movably inserted into a track groove. The connecting bearing can move along the slotting direction of the track groove. Under the action of the axial drive assembly and the oscillating drive assembly, the connecting bearing drives the funnel to move.

[0013] Furthermore, the landing sampler's structural plates include a +Z plate, a -Z plate, a +Y plate, and a -Y plate.

[0014] +X plate and -X plate. The origin of the coordinate system is the center of mass of the lander sampler. The direction from the origin to the +Z plate is the +Z direction. The +X direction is the direction of flight. The +Y direction is determined by the right-hand rule.

[0015] The swing shaft seat is detachably mounted on the +Z plate. The track plate is detachably mounted on the +Z plate.

[0016] Furthermore, the container body is a frustum-shaped barrel, wider at the top and narrower at the bottom. A flange extends outward from the open top of the container body.

[0017] Furthermore, it also includes a container fixing assembly. The container fixing assembly includes an upper support frame and a lower support frame. Both the upper and lower support frames include clamps and connecting rods. The two ends of the connecting rods are connected to the landing sampler and the clamps, respectively. The clamps of the upper and lower support frames are fitted around the outer periphery of the container body to provide axial positioning for the container body.

[0018] Furthermore, the pouring outlet is a slightly curved arc-shaped notch.

[0019] Furthermore, the bottom vibration assembly includes a vibration motor, a container striking component, a torsion spring clamping sleeve, a container striking component shaft, an assembly mounting base, a shaft torsion spring, and an eccentric block.

[0020] The container striking component includes a U-shaped groove and a motor enclosure. The opening of the U-shaped groove faces upward. The motor enclosure is disposed within the opening of the U-shaped groove. A striking boss is provided on the upper surface of the motor enclosure. The excitation motor is disposed within the motor enclosure. The motor shaft of the excitation motor extends out of the motor enclosure. The eccentric block is fixed to the motor shaft. The U-shaped groove includes a base plate and two side plates. The end of the side plates away from the motor enclosure extends outward. The extended ends of the two side plates form a component mounting base accommodating space.

[0021] The component mounting base is detachably mounted on the landing sampler. The component mounting base is arranged within an accommodating space. The container striking component's rotating shaft passes through two side plates and the component mounting base. Torsion springs are fitted at both ends of the container striking component's rotating shaft. The two torsion arms of the torsion springs are respectively fixed to the lower surface of the base plate and the landing sampler. A torsion spring retaining sleeve is also fitted on the container striking component's rotating shaft. The torsion spring retaining sleeve provides axial positioning for the rotating shaft's torsion springs.

[0022] Under the combined action of the excitation motor and the shaft torsion spring, the striking boss strikes the lower surface of the container body.

[0023] Furthermore, the funnel body has a wide-mouthed, square-topped structure. A flange is provided on the side wall of the funnel body, and in the initial state, the lower surface of the flange is attached to the top seal of the container.

[0024] Furthermore, the axial drive component is a lead screw.

[0025] The present invention also discloses a method for collecting samples from the surface of extraterrestrial bodies using the above-described device.

[0026] The method includes the following steps:

[0027] 1) Sample Collection. The sample is carried by the sampling end to the upper opening of the funnel body for pouring and releasing. The excitation motor performs excitation motion to assist the sample in entering the container body. With the assistance of the excitation assembly, the problem of sample accumulation is solved, making the sample dense.

[0028] 2) Sample Sealing. After sampling is completed, the axial drive assembly moves the funnel support column upward. The lower edge of the funnel body releases the restriction on the rotation of the top sealing valve. Under the restoring force of the valve torsion spring, the top sealing valve rotates, sealing the pouring outlet and completing the container sealing process.

[0029] 3) Sample transfer. The sample transfer end grips the initial sealed container and moves it towards the sealed encapsulated container.

[0030] 4) The device is restored to its initial state.

[0031] Further, after step 2), the axial drive assembly drives the funnel body to continue rising until the connecting bearing reaches the deflection section. Under the restoring force of the swing drive torsion spring, the funnel assembly swings around the swing shaft seat and finally stops, completing the funnel swing action.

[0032] The technical effects of this invention are beyond doubt:

[0033] A. The allowable width error of the sample can be large, which reduces the difficulty of sample collection and facilitates the collection of soil from the surface of extraterrestrial objects;

[0034] B. It can slowly introduce samples taken from the ground surface into the packaging container and ensure a low leakage rate in the collection and receiving process;

[0035] C. The packaging action is simple to trigger, effectively avoiding external factors such as sampling samples clogging the packaging equipment, and can realize the automatic packaging process;

[0036] D. Sufficient space is provided for handling, which reduces the design difficulty of transferring and moving the sampler;

[0037] E. It can adapt to complex environmental conditions throughout the entire flight process, including launch, Earth-Moon transfer, and landing on the lunar surface. Attached Figure Description

The lower edge of the funnel body 6-1 releases the restriction on the rotation of the top sealing valve 1-3. Under the restoring force of the valve torsion spring 1-4, the top sealing valve 1-3 rotates, sealing the pouring outlet 1-11, completing the container sealing action.

[0085] 3) Funnel rotation. The axial drive assembly 3 drives the funnel body 6-1 to continue rising until the connecting bearing 6-5 reaches the deflection section 5012. Under the restoring force of the swing drive torsion spring 4-2, the funnel assembly 6 swings around the swing shaft seat 4-3 and finally stops, completing the funnel rotation action.

[0086] 4) Sample transfer. The sample transfer end grips the initial sealed container 1 and moves it towards the sealed encapsulation container.
