[0055] To further illustrate the technical solution of the present invention, Figures 1-9 , the following specific embodiments are provided.

[0056] Example 1

[0057] This embodiment provides a sampling device for an extraterrestrial object detector, such as Figure 1 As shown, the device may include at least a sampling head 1 and a drive mechanism. The extraterrestrial object detector may drill a pre-set exploration hole on the surface of the extraterrestrial object and then use a sampling device to sample soil at different depths. The sampling head 1 is driven by the drive mechanism to be moved from the extraterrestrial object detector into the exploration hole. The sampling head 1 can sample soil at different depths of the extraterrestrial object to understand the distribution of different components in the extraterrestrial soil.

[0058] The extraterrestrial body detector of this embodiment can be launched into the surface of the extraterrestrial body through a bullet filled with gunpowder, and form an exploration hole on the surface of the extraterrestrial body. Of course, the exploration hole can also be made by other methods, which are not specifically limited here.

[0059] It can be understood that the soil in this embodiment can be a substance in a solid state, a solid-liquid mixed state, or a solid-liquid-gas mixed state.

[0060] This embodiment exemplifies the structure of the sampling head 1, such as Figure 2 and Figure 3As shown, the sampling head 1 may include a housing 11, a sampling shovel 12, and a sampling shovel drive mechanism 13. The housing 11 has a sampling port 11a formed on its outer surface. The sampling shovel 12 is disposed within the housing 11 and can extend from the sampling port 11a to collect soil from an extraterrestrial body. The sampling shovel drive mechanism 13 is used to drive the sampling shovel 12 to extend and retract within the sampling port 11a. To facilitate insertion of the sampling head 1 into the exploration borehole, the cross-sectional area at the bottom of the housing 11 of the sampling head 1 may be smaller than that at the middle and top. The housing 11 may be shaped like a bullet, but other shapes, such as a spindle, are also possible, and are not specifically limited herein.

[0061] Preferably, Figure 4 and Figure 6 As shown, the sampling shovel 12 can be slidably disposed within the housing 11 and can be slid out of the housing 11 for sampling; preferably, the sampling shovel 12 can be extended from the housing 11, and the sampling port 11a is located on one side of the moving direction of the sampling head 1. To facilitate understanding of how the sampling head 1 performs sampling, this embodiment defines the direction in which the sampling shovel 12 extends from the housing 11 as the horizontal direction, and the moving direction of the sampling head 1 within the exploration hole as the vertical direction. The horizontal and vertical directions may or may not be perpendicular to each other, and the angle between the horizontal and vertical directions may be less than or equal to 90° and greater than 45°. Of course, the horizontal and vertical directions being perpendicular is the best embodiment of this embodiment. This allows accurate sampling based on the specific depth of the exploration hole, facilitating analysis of the soil composition of extraterrestrial bodies at different depths. In one embodiment of the sampling shovel 12 of the present invention, the sampling shovel 12 can be formed with a hollow cavity 12a, and the hollow cavity 12a is provided with an opening in the same direction as the sampling port 11a. When the sampling shovel 12 is extended from the opening, it is inserted into the soil of the extraterrestrial body for sampling. The soil of the extraterrestrial body is filled in the hollow cavity 12a. When the sampling shovel 12 is retracted into the shell 11, the sampling head 1 is driven by the sampling shovel driving mechanism 13 to move out of the exploration hole and retract into the extraterrestrial body detector to complete the sampling work. To further improve the reliability of sampling, the sampled soil is filled in the hollow cavity 12a during the sampling process. A plurality of notches 12b are formed on the opening edge of the sampling shovel 12. The length direction of the notches 12b is the same as the movement direction of the sampling shovel 12, and the notches 12b are connected to the hollow cavity 12a. In this way, when sampling, the opening of the sampling shovel 12 expands outward, increasing the clamping force of the side wall of the hollow cavity 12a on the sampled soil, thereby ensuring the reliability of the sampling process. Of course, the hollow cavity 12a can also be configured as a conical cavity with a large cross-sectional area at the opening and a small cross-sectional area at the bottom, which can also increase the clamping force during the soil sampling process. In this embodiment, the opening edge of the sampling shovel 12 can be polished into a sharp blade to facilitate the smooth insertion of the sampling shovel 12 into the sampled soil layer during the sampling process, thereby reducing the resistance to insertion.

[0062] For ease of understanding, the sampling shovel 12 can slide in and out of the sampling port 11a by, but is not limited to, the following structure:

[0063] like Figure 6 As shown, a guide key 12c is formed on the outer surface of the sampling shovel 12, and a guide groove is provided at the sampling port 11a of the shell 11. The guide key 12c can be slidably provided in the guide groove. The setting of the guide key 12c and the guide groove enables the sampling shovel 12 to slide in and out of the sampling port 11a of the shell 11. Of course, a guide key 12c can also be fixed at the sampling port 11a of the shell 11, and a guide groove is formed on the outer surface of the sampling shovel 12.

[0064] Preferably, Figure 3-Figure 5 As shown, the sampling shovel drive mechanism 13 may include a sleeve 131, a drive rope 132, a winch 133 and a first motor 134; wherein, the sleeve 131 is rotatably arranged in the housing 11, and the sleeve 131 is sleeved on the sampling shovel 12 and threadedly connected to the sampling shovel 12, so that the sampling shovel 12 is moved laterally in the sampling port 11a by the forward and reverse rotation of the sleeve 131, that is, the sampling shovel 12 is slid in and out of the sampling port 11a; one end of the drive rope 132 is forwardly wound around the outer peripheral surface of the sleeve 131, and the other end thereof is reversely wound around the outer peripheral surface of the sleeve 131; the drive rope 132 is wound around the winch 133, and the first motor 134 drives the winch 133 to rotate. To facilitate the control of the forward and reverse rotation of the sleeve 131, two annular grooves surrounding the axis of the sleeve 131 can be provided on the outer surface of the sleeve 131, wherein one end of the drive rope 132 is fixed to the bottom of one annular groove and wound several times in the forward direction, and the other end of the drive rope 132 is fixed to the bottom of the other annular groove and wound several times in the reverse direction. The middle part of the rope also produces several turns on the winch 133. In this way, the winch 133 is driven by the motor in the forward and reverse directions. The rotation of the winch 133 drives the sleeve 131 through the rope to achieve forward and reverse rotation, and finally realizes the sliding of the sampling shovel 12 in and out of the sampling port 11a. The advantage of rope drive is that it can adapt to the shape changes of the exploration hole. When the exploration hole is a non-straight hole, it can adapt to the shape changes of the exploration hole and reduce the travel resistance of the sampling head 1.

[0065] like Figure 1 As shown, the capstan 133 of the sampling shovel drive mechanism 13 is rotatably mounted on a frame 135. A motor is fixed to the frame 135 and is in driving connection with the capstan 133, allowing the motor to rotate on the frame 135 to drive the capstan 133. The frame 135 can serve as a part of the sampling shovel drive mechanism 13, facilitating modularization and ease of assembly. A battery 136 is also mounted on the frame 135 to power the first motor 134.

[0066] Further, if Figure 1As shown, the driving mechanism may include a winding frame 21, a flexible sleeve 22 and a second motor; wherein a winding drum may be provided at the center of the winding frame 21 so that the flexible sleeve 22 can be wound on the winding drum of the winding frame 21, so that the flexible sleeve 22 can be transported when the winding frame 21 rotates, and the flexible sleeve 22 is provided with the above-mentioned driving rope 132. The two ends of the driving rope 132 pass through one end of the flexible sleeve 22 and pass through the other end of the flexible sleeve 22, and are fixedly connected to the above-mentioned sleeve 131. One end of the driving rope 132 is fixed to the sleeve 131. The sampling shovel drive mechanism 13 is wound in a forward direction on the spool 31, and its other end is wound in a reverse direction. The capstan 133 of the sampling shovel drive mechanism 13 is rotatably mounted on the winding frame 21. To facilitate assembly, the frame 135 can be fixed to the winding frame 21, and the capstan 133 can be rotatably mounted on the frame 135. The first motor 134 is fixed to the frame 135 and is in transmission connection with the capstan 133. In this way, the sampling shovel drive mechanism 13 can be modularly assembled and then the frame 135 can be fixed to the winding frame 21. The winding frame 21 is driven by a second motor, wherein the second motor and the winding frame 21 form a transmission connection, which can be a gear drive, belt drive, chain drive, or a direct connection between the motor and the winding frame 21. The specific transmission method is not specifically limited here. In one embodiment, the winding frame 21 can be mounted on an extraterrestrial object detector, and the rotation of the second motor can deliver the sampling head 1 into a predetermined exploration hole to achieve sampling. Inserting the sampling head 1 into the exploration hole through the flexible sleeve 22 can adapt to changes in the shape of the exploration hole, especially a curved hole with a certain curvature. At the same time, placing the drive rope 132 in the flexible sleeve 22 can simplify the structure and facilitate controlling the sampling head 1 to a predetermined position for sampling via the drive rope 132. In one embodiment, the drive rope 132 can be a steel wire rope.

[0067] This embodiment can be applied to the survey of soil on the surface of extraterrestrial bodies such as Mars and the Moon, but is not limited thereto. It can also be applied to other extraterrestrial bodies and is not specifically limited here.

[0068] Example 2

[0069] This embodiment provides a sampling device for an extraterrestrial object detector, such as Figure 1 、 Figure 7 and Figure 8 The sampling device is arranged on the extraterrestrial body detector. The extraterrestrial body detector can drill an exploration hole on the surface of the extraterrestrial body. The sampling device may include a sampling head 1 and a sampling head 1. The sampling head 1 can collect soil from the extraterrestrial body in the exploration hole; the driving mechanism can drive the sampling head 1 to move into the exploration hole.

[0070] The method of drilling a hole in the extraterrestrial body by the extraterrestrial body detector is the same as that in Example 1.

[0071] The sampling head 1 may include a shell 11, a sampling shovel 12 and a sampling shovel driving mechanism 13; wherein, a sampling port 11a is formed on the outer surface of the shell 11; the sampling shovel 12 is arranged in the shell 11 and can be extended from the sampling port 11a to collect soil from an extraterrestrial body; the sampling shovel driving mechanism 13 is used to drive the sampling shovel 12 to move so that the sampling shovel 12 can be extended and retracted in the sampling port 11a.

[0072] In one embodiment, the sampling head 1 may further include a sample chamber 14, a first spring 15, and a second spring 16; wherein the sample chamber 14 is slidably disposed within the housing 11 and may extend from the bottom of the housing 11. The sample chamber 14 and the housing 11 form the outer shape of the sampling head 1, and the outer shape of the sampling head 1 may be the same as the outer shape of the housing 11 in Example 1. A cavity is formed within the sample chamber 14, and the bottom of the housing 11 also has an opening. The top of the sample chamber 14 extends from the opening at the bottom of the housing 11 into the housing 11, that is, a portion of the sample chamber 14 extends into the housing 11 and the two are relatively slidable. A first spring 15 is provided between the sample chamber 14 and the housing 11, and both ends of the first spring 15 abut against the opening of the sample chamber 14, i.e., the top position within the housing 11, to achieve telescopic movement of the sample chamber 14 on the housing 11. To facilitate sampling, two sampling shovels 12 are provided in this embodiment. Each sampling shovel 12 is equipped with a hinged portion 12d and a tensioning portion. The hinged portions 12d of the two sampling shovels 12 are located on either side of the centerline of the first spring 15 and are respectively hinged to the sample chamber 14. The hinged portions 12d are located within the sample chamber 14. Slots 12b are provided on either side of the sample chamber 14, and a portion of the slots 12b partially overlaps with the sampling port 11a on the housing 11. Rotation of the sampling shovel 12 allows the sampling shovel 12 to extend and retract within the sample chamber 14, further extending and retracting the sampling port 11a of the housing 11. When the two sampling shovels 12 are extended, they extend obliquely upward to allow the upward movement of the sample chamber 14 to sample. After sampling, the two sampling shovels 12 need to be retracted to facilitate the withdrawal of the sampling head 1 from the exploration hole. In one embodiment, the tensioning portions of the two sampling shovels 12 are connected by a second spring 16, and the tension of the second spring 16 causes the two sampling shovels 12 to retract. Preferably, the two sampling shovels 12 are symmetrically positioned on either side of the centerline of the first spring 15, ensuring uniform force during sampling and improving sampling efficiency. Compared to Example 1, after sampling within the predetermined depth, the movement of the sample chamber 14 may result in inaccurate sampling depth. Preferably, the second spring 16 may be a tension spring, and the second spring 16 may be a compression spring. The extension and retraction of the two sampling shovels 12 within the sampling port 11a are achieved by the sampling shovel drive mechanism 13, while the sampling process is controlled by the sampling control mechanism.

[0073] In one embodiment, a toothed blade is formed at the end of the sampling shovel 12. During the sampling process, the sampling shovel 12 scrapes the surface of the exploration hole of a preset depth to take samples, and the sampled soil falls on the upper surface of the sampling shovel 12 in sequence. Since the sampling shovel 12 is inclined upward, the scraped sampled soil falls from the upper surface of the sampling shovel 12 into the cavity of the sample chamber 14 to complete the sampling.

[0074] The structure of the sampling shovel driving mechanism 13 is exemplified below, but is not limited to the following.

[0075] The sampling shovel drive mechanism 13 may include a drive rope 132, a winch 133, and a first motor 134. The two sampling shovels 12 may be connected to the drive rope 132, respectively. The specific connection structures may be various, with two structures being exemplified. The two sampling shovels 12 may be directly and fixedly connected to the drive rope 132. The extension and retraction of the drive rope 132 enable the sampling shovels 12 to rotate within the sample chamber 14, thereby enabling the sampling shovels 12 to extend and retract within the sampling port 11a. Alternatively, the two sampling shovels 12 may be hinged to a connector 137, which is fixedly connected to the drive rope 132. The hinge position of each sampling shovel 12 on the connector 137 does not coincide with the hinge position of the sampling shovel 12 within the sample chamber 14. The hinge axis between the sampling shovel 12 and the connector 137 may be higher than the hinge axis between the sampling shovel 12 and the sample chamber 14.

[0076] On the basis of the above improvements, the driving mechanism may further include a winding frame 21, a flexible sleeve 22 and a second motor; wherein the capstan 133 is rotatably arranged on the winding frame 21, the second motor can drive the winding frame 21 to rotate, the second motor and the winding frame 21 are transmission-connected, the flexible sleeve 22 is wound on the winding frame 21, one end of the driving rope 132 is fixed on the capstan 133 and can be wound around the capstan 133 for several turns, the other end of the driving rope 132 passes through the winding sleeve and is fixedly connected to the two sampling shovels 12, the sampling head 1 can be sent into the exploration hole through the flexible sleeve 22 by driving the capstan 133 to rotate by the second motor, and the sampling shovel 12 can be extended from the sampling port 11a at a predetermined depth of the exploration hole by driving the capstan 134 to realize sampling. The specific sampling process is realized by the upward movement of the sample chamber 14 relative to the shell 11, and the movement of the sample chamber 14 relative to the shell 11 can be realized by the sampling control mechanism.

[0077] In one embodiment, the sampling control mechanism may include a control rope 31, a winding reel, and a third motor. The reel is rotatably mounted on the winding frame 21 and is rotated by the third motor. One end of the control rope 31 is fixed to the reel and can be wound around it several times. The other end of the control rope 31 passes through one end of the flexible sleeve 22 and exits the other end of the flexible sleeve 22 to be fixed to the sample chamber 14. Both the drive rope 132 and the control rope 31 are disposed within the flexible sleeve 22, simplifying the structure while facilitating the controlled sampling of soil from an extraterrestrial object within the exploration borehole via the rope. As the sampling shovel 12 extends obliquely upward from the sampling port 11a, the third motor drives the winding reel to rotate, driving the sample chamber 14 upward relative to the housing 11, causing the sampling shovel 12 to scrape against the sidewall of the exploration borehole to collect samples. In this embodiment, the capstan 133 and the reel are both mounted on the spool 21. As the spool 21 rotates, the sampling head 1 is fed into the exploration borehole through the flexible sleeve 22, and the capstan 133 and reel rotate along with the spool 21. Both the capstan 133 and the reel are driven by a motor, enabling control of the extension and retraction of the sampling shovel 12 and the sampling process. Compared to Example 1, this embodiment utilizes two motors to achieve both extension and retraction of the sampling shovel 12 and sampling, whereas Example 1 utilizes only a single motor. Furthermore, during the sampling process, this embodiment requires controlling the sample chamber 14 to reciprocate up and down relative to the housing 11 multiple times to obtain a predetermined amount of soil, whereas in Example 1, the sampling shovel 12 only needs to be extended once to complete the sampling. While this embodiment has a relatively complex structure compared to Example 1, and the amount of each sample is relatively small, it still substantially achieves the goal of sampling extraterrestrial soil at various depths within the exploration borehole.

[0078] In this embodiment, the driving rope 132 and the control rope 31 can be steel ropes.

[0079] While the exemplary embodiments of the present disclosure have been specifically illustrated and described above, it should be understood that the present disclosure is not limited to the detailed structures, configurations, or implementations described herein; rather, the present disclosure is intended to encompass various modifications and equivalent configurations within the spirit and scope of the appended claims.
