Description

Technical Field

[0001] The present invention relates to the technical field of lunar soil collection devices, and in particular to a lunar soil collection vehicle based on high voltage static electricity. Background Art

[0002] Lunar exploration is one of the most challenging fields in the world today, and manned lunar landing, development of lunar resources, and establishment of lunar bases are the main competitive hotspots in aerospace engineering. Establishing a lunar base is the basis for long-term lunar exploration and development. It is foreseeable that the construction of a lunar base will require the collection of a large amount of lunar soil particles as sintering materials. At the same time, in the subsequent lunar production activities and lunar resource development process, lunar soil collection will become increasingly irreplaceable.

[0003] Traditional mechanical sampling methods mainly include profile sampling and surface sampling. Profile sampling mostly uses the method of drilling and coring, which has the problems of large size, weight, and power consumption of the sampling machine, and the requirements for the sampling platform are high due to the drilling reaction torque and drilling pressure; surface sampling mainly includes impact sputtering and shovel sampling, which also have the problems of poor stability and mechanical disturbance.

[0004] Compared with the traditional mechanical sampling method, the high-voltage electrostatic collection method can achieve lunar soil sampling with a smaller and lighter device, greatly reducing the size and weight of the sampling machine. At the same time, the high-voltage electrostatic collection method avoids direct contact between the device and the lunar soil, and will not damage the device due to mechanical vibration generated by sampling, and the device stability is better.

[0005] At present, domestic scholars use a high-voltage DC power supply to connect to the O-type sampling electrode to provide an electric field driving force for the target particles, and at the same time generate an electric field to guide the particles to move toward the sample container. The principle is that the ground electrode contacts the target particles, forcing the particle potential to be zero and providing the particles with sufficient free charge. The sample container collects the particles that jump up due to the electric field, and keeps them in the sample collection cavity through electrostatic adsorption and other methods to achieve the effect of particle collection. The O-type sampling electrode is arranged inside the sample container and supported by an insulating column and isolated from the sample container by a certain height. The O-type sampling electrode is connected to the positive electrode of the high-voltage power supply through the positive electrode connector, and the ground electrode is connected to the negative electrode of the high-voltage power supply through the negative electrode connector. A small hole is designed at the bottom of the electrostatic sampler to directly expose the particles in the target area to the electric field range, so as to establish a transmission channel with minimum resistance between the O-type sampling electrode and the target particles.

[0006] The problem with this device is that the sampled particles will accumulate as the sampling time increases, which will cause the sampling electrode to directly contact the sampled particles and produce a "bridge effect", greatly reducing the sampling capacity. Therefore, in order to solve the above problem, it is very practical to develop a lunar surface soil collection vehicle based on high-voltage static electricity. Summary of the invention

The drag electrode 13 is made of a copper sheet with a relatively soft material, one end of which is wound around the retaining frame 122 and glued with adhesive tape to keep 122 connected to the roller mounting frame. When working, the drag electrode 13 is negatively charged, which further charges the particles and can form a complete collection electric field with the positively charged collection electrode.

[0063] Specific implementation method seven: Combination Figures 1 to 16 This embodiment is described. The difference between this embodiment and the specific embodiment 6 is that the collecting electrode assembly 2 includes a stepper motor 21, an electrode mounting seat 22, a tail bearing 24 and two sawtooth electrodes 23. The stepper motor 21 is mounted on a motor fixing seat at the top of a support plate 61 in a bottom support assembly 6, and the tail bearing 24 is mounted on a bearing seat at the top of a support plate 61 in another bottom support assembly 6. The electrode mounting seat 22 is arranged between the stepper motor 21 and the tail bearing 24, and one end of the electrode mounting seat 22 is sleeved on the power output shaft of the stepper motor 21 and rotates synchronously with the power output shaft of the stepper motor 21. The other end of the electrode mounting seat 22 is inserted in the tail bearing 24 and is rotatably connected to the bearing seat through the tail bearing 24. The two sawtooth electrodes 23 are attached to the side of the electrode mounting seat 22 away from the roller electrode assembly 1, and an arrangement gap and an arrangement angle are provided between the two sawtooth electrodes 23, and the arrangement gap is 10 mm and the arrangement angle is 120°. Other components and connection methods are the same as those of the specific embodiment 6.

[0064] In this embodiment, the two sawtooth electrodes 23 are arranged relative to each other with a certain angle and relative distance. After the high-voltage module is connected, a high-voltage electrostatic field is formed to drive the charged particles to jump and pass through the two sawtooth electrodes. The entire structure of the collecting electrode is fixed to the stepper motor, and its angle relative to the ground can be adjusted to adapt to different terrains.

[0065] Specific implementation method eight: Combination Figures 1 to 16This embodiment is described. This embodiment is different from the seventh embodiment in that the transport electrode 4 includes a negative plate 41, a positive plate 42 and an insulating plate 43. The negative plate 41 is a T-shaped plate, the positive plate 42 is a U-shaped plate, the vertical portion of the negative plate 41 is arranged between two vertical portions of the positive plate 42, and the vertical portion of the negative plate 41 is equal to the spacing between each vertical portion of the positive plate 42, the insulating plate 43 is arranged in the gap between the negative plate 41 and the positive plate 42, and the negative plate 41 is fixedly connected to the positive plate 42 through the insulating plate 43. Other components and connection methods are the same as those of the seventh embodiment.

[0066] In this embodiment, the transport electrode 4 is designed to be comb-shaped, with one side connected to a low level and the other side connected to a high level, so as to form an alternating electric field. The insulating layer laid between the transport electrodes can make the entire surface of the transport electrode flat, reduce the accumulation of particles in the grooves between the electrodes, and facilitate the subsequent cleaning of the accumulated particles.

[0067] In conjunction with the instruction manual Fig.15 As shown in the figure, the working principle of the particle transport module is as follows: when the particle does not contact the electrode, it is polarized by the electric field and moves into the electric field under the action of the dielectrophoretic force. When the particle begins to contact the positive plate, it is still subject to the dielectrophoretic force to the right, and the particle begins to be charged with positive charge; when the particle leaves the positive plate, the particle is positively charged, and is subject to the Coulomb force applied by the electric field between the positive and negative plates, and overcomes the dielectrophoretic force to the left, and moves to the right; when the particle begins to contact the negative plate, it is subject to the Coulomb force and dielectrophoretic force to the right, and begins to be charged with negative charge; when the particle leaves the negative plate, it is subject to the dielectrophoretic force to the left and the Coulomb force applied by the electric field between the positive and negative electrodes to the right. This reciprocating process achieves unidirectional transport. In order to improve the migration of the transport electrode 4, the transport electrode 4 is arranged at an angle, with the side close to the collecting electrode assembly 2 arranged lower and the side close to the lunar soil temporary storage assembly 5 arranged higher. In this way, when particles leave the transport electrode 4, they can more easily enter the lunar soil temporary storage assembly 5 for temporary storage.

[0068] Specific implementation method nine: Combination Figures 1 to 16The present embodiment is described. The present embodiment is different from the specific embodiment eight in that a cleaning assembly 3 is further provided in the collection trolley.

The two slide brackets 34 are relatively arranged at the two ends of the bottom of the screw sealing slide 31 along the center line of the length direction of the screw sealing slide 31. The top of each slide bracket 34 is detachably connected to the screw sealing slide 31. The bottom of each slide bracket 34 is detachably connected to a corresponding bottom support assembly 6. The brush mounting bracket 32 ​​is installed on the sliding end of the screw sealing slide 31, and the brush mounting bracket 32 ​​extends to the bottom of the screw sealing slide 31. The brush 33 is installed at the bottom of the brush mounting bracket 32, and the brush 33 is arranged in correspondence with the top of the transport electrode 4.

[0069] The screw sealing slide 31 includes a cover plate 311, a screw motor 312, a motor mounting seat 313, a sealing platform 314, a screw 315, a screw nut seat 316, a screw nut 317 and a screw bearing 318. The screw 315 is arranged in the sealing platform 314, and the length extension direction of the screw 315 is the same as the length extension direction of the sealing platform 314. One end of the screw 315 is inserted into an end wall of one end of the sealing platform 314 and is rotatably connected to the sealing platform 314 through the screw bearing 318. The other end of the screw 315 is provided with a screw motor 312, and the other end of the screw 315 is connected to the power output shaft of the screw motor 312 through a coupling. The housing of the screw motor 312 is installed on the inner bottom of the sealing platform 314 through the motor mounting seat 313. The cover plate 311 is arranged at the top opening of the sealing platform 314, and the cover plate 311 is connected to the sealing platform 314 through bolts. 4 is detachably connected, a through gap is provided between each long side of the cover plate 311 and a corresponding long side of the sealing platform 314, a lead screw nut 317 is sleeved on the lead screw 315, and the lead screw nut 317 is threadedly connected to the lead screw 315, a lead screw nut seat 316 is arranged on one side of the lead screw nut 317, and the lead screw nut seat 316 is sleeved on the lead screw 315, and the lead screw nut seat 316 is detachably connected to the lead screw nut 317 by bolts, and both ends of the lead screw nut seat 316 extend to the outside of the sealing platform 314 through corresponding through gaps, the brush mounting frame 32 is a U-shaped frame, the brush mounting frame 32 is arranged below the sealing platform 314, and each leg at the top opening of the brush mounting frame 32 is detachably connected to one end of the lead screw nut seat 316, and the brush mounting frame 32 can reciprocate along the length extension direction of the lead screw 315 with the lead screw nut seat 316. Other components and connection methods are the same as those of the specific embodiment eight.

[0070] In the present embodiment, considering that after the transport electrode 4 has been transported for a long time, particles will inevitably accumulate on the surface of the transport electrode, and this problem cannot be solved by the transport electric field, and needs to be cleaned with the help of additional means, a cleaning device 3 is installed above the electrode, and the device is composed of a screw sealing slide 31 and a brush 33, etc. The brush 33 is installed below the screw sealing slide 31, and moves synchronously with the screw nut seat 316, and sweeps over the surface of the transport electrode 4 for cleaning under the drive of the screw motor 312. It is worth noting that since the transport electrode 4 is tilted, in order to ensure the accuracy of cleaning, the brush 33 and the screw sealing slide 31 also need to be tilted, and the tilt angle is the same as the tilt angle of the transport electrode 4. The basis for realizing the tilted arrangement of the brush 33 and the screw sealing slide 31 is to optimize the top of the slide bracket 34, so that it is set as an inclined surface, so as to achieve the purpose of tilting the screw sealing slide 31.

[0071] Specific implementation method ten: Combination Figures 1 to 16 This embodiment is described. The difference between this embodiment and the ninth embodiment is that the lunar soil temporary storage assembly 5 includes a solenoid valve mounting seat 51, a solenoid valve lock 52 and a temporary storage bin 53. The temporary storage bin 53 is set on two bottom support assemblies 6. The solenoid valve lock 52 is arranged on one side of the temporary storage bin 53. The housing of the solenoid valve lock 52 is installed on a support plate 61 in a bottom support assembly 6 through the solenoid valve mounting seat 51.

[0072] In this embodiment, the lunar soil temporary storage assembly 5 is used to temporarily store dust particles captured by the collector, and is mainly composed of a solenoid valve lock 52 and a temporary storage bin 53. The particles are transported to the temporary storage bin 53 by the transport electrode 4. Due to the strong gravity of the ground environment and the limitation of the maximum transport slope of the transport electrode, the front of the temporary storage bin 53 is relatively low, and the rear requires a certain height to prevent the particles from gaining a large speed in the transport electric field and flying out of the temporary storage bin area. The solenoid valve lock 52 is used to lock the temporary storage bin, and at the same time, it is powered on and unlocked when the temporary storage bin reaches the upper limit of capacity. The temporary storage bin 53 is extracted by the robotic arm carried by the lunar rover to transport the collected particles. The tail of the temporary storage bin 53 is provided with a pulling plate 54 for cooperation with the robotic arm carried by the trolley.

[0073] The present invention has been disclosed as above with preferred implementation cases, but it is not intended to limit the present invention. Any technician familiar with the profession can make some changes or modifications to equivalent implementation cases with equivalent changes by using the above-disclosed structures and technical contents without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above implementation cases based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.

[0074] How it works

[0075] The working principle of the lunar soil collection vehicle described in the present application is as follows: when the collection vehicle moves forward, the ground particles are charged by contacting the roller electrode 11 at the front end of the device, and are supplemented with charge by the dragging electrode 13. They are driven by the electric field formed by the collection electrode under the collection electrode assembly 2, thereby bouncing and falling between the collection electrode assembly 2 and the transport electrode 4; the particles are further driven by the alternating electric field generated by the transport electrode 4, and the movement direction is opposite to the overall movement direction of the device, thereby falling into the temporary storage bin 53; when the temporary storage bin is full, the solenoid valve lock 52 is opened, and the temporary storage bin 53 can be moved out, emptied, and then put back in place, realizing a complete collection process;

[0076] In the above working process, the control system plays a regulatory role. Fig.16 It is explained that in order to adjust the working angle of the collecting electrode assembly 2, clean the dust accumulated on the surface of the transport electrode 4, and make the collecting field adapt to the terrain with different slopes, a stepper motor 21 is introduced for control. The stepper motor controller can control the forward and reverse rotation of the stepper motor 21 and adjust the speed of the stepper motor;

[0077] The working control of the cleaning component 3 is mainly to control the DC screw motor 312. Generally speaking, the cleaning mechanism does not need to be operated and only needs to be turned on when the transport electrode 4 is blocked.

[0078] The high-voltage module is in the on state when the collector is working normally and is only temporarily disconnected when the collector needs to be adjusted. For example, when the transport electrode is blocked and the cleaning component 3 is in working state, the high-voltage module needs to be disconnected to prevent the high voltage from being connected by the cleaning component 3 and causing a short circuit.

[0079] The solenoid valve lock 52 will be powered on and unlocked only when the temporary storage bin 53 reaches the upper capacity limit and the collected particles inside need to be transported.

[0080] In order to control the operation of the above mechanism, a relay is used to control the current on and off. The selected relay is a 5V4-way relay, the input end is connected to the first four output ports of the single-chip microcomputer, and can be directly triggered by the high-level signal of the single-chip microcomputer. The output end of the relay has 3 ports, namely normally open, normally closed and common ports. The STC89C52 single-chip microcomputer is used as the signal transmission source of the relay, and the HC-06 Bluetooth wireless communication module is added to simplify the control means.

[0081] HC-06 Bluetooth wireless communication module is used to transmit control instructions. The receiving pin and sending pin of the Bluetooth chip are connected to the receiving pin and sending pin of the microcontroller respectively. Program the microcontroller. When the microcontroller receives 01, 02, 03, 04 signals through the Bluetooth module, the level of 01, 02, 03, 04 bits of its P1 port changes, thereby controlling the on and off of the relay.

[0082] Based on the above device and the above working principle, the applicant conducted experimental verification on the lunar soil collection vehicle provided by this application, which mainly included the following experiments:

[0083] Collection experiment of collecting electrodes: two sawtooth electrodes 23 are placed according to the theoretically set positions and postures, and are spaced a certain distance from the roller electrode 11 and the dragging electrode 13. The entire collection module is installed on the laid sampling particles. The roller electrode 11 and the dragging electrode 13 are negatively charged, and the two sawtooth electrodes 23 are positively charged. The roller electrode 11, the dragging electrode 13 and the sawtooth electrode 23 are controlled to maintain relative positions and move to the right for a certain distance, and a considerable number of sampling particles are collected, which proves that the collection electrode 23 has a certain collection ability.

[0084] Transport electrode transport experiment: several long strip metal electrodes are placed on a flat plate at equal intervals, the electrodes are alternately charged with positive and negative electricity, and an insulating layer made of PVC board is laid in the interval between the electrodes so that adjacent electrodes are insulated and separated, and the entire electrode surface is flat (constructing transport electrode 4). A certain number of sampling particles are placed on the left side of transport electrode 4. After power is turned on, it can be observed that most of the sampling particles move to the right and finally migrate to the other side of the transport electrode. It can be seen that the transport electrode has a good transport ability;

[0085] Overall device experiment: The roller electrode assembly 1, the collecting electrode assembly 2, the transport electrode 4 and the temporary storage assembly 5 of the lunar soil are installed on the bottom support assembly 6. The tail of the bottom support assembly 6 is provided with a driven wheel mechanism 62, so that the whole device has the ability to move. The whole device is placed on the plane where the particles are laid, and each electrode is energized, and the whole device is moved forward by external traction. It was observed that particles constantly jumped from the middle of the collecting electrode during the movement, fell on the transport electrode 4, and were transported to the temporary storage bin 53. After the experiment, a certain number of sampling particles were collected in the temporary storage bin 53. This experiment verified that the whole collection device can guarantee a certain sampling capacity during the movement.
