[0044] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0045] The radiation emitted by the sun still has a power of millions of kilowatts when it reaches the earth's surface. The energy that reaches the earth every second is equivalent to the heat released by burning millions of tons of coal. After such a huge amount of energy is focused through an array mirror to form a light cone, it can generate super high temperatures, enough to melt the sand in the desert. The melted sand will solidify after natural cooling, thus achieving the purpose of desert control.

[0046] Based on the above invention concept, this embodiment provides a beam cone sintering vehicle and a sand control method, which utilizes sunlight to melt sand and agglomerate it, thereby controlling the desert. The beam cone sintering vehicle is used to implement the beam cone sintering sand control method, but the beam cone sintering sand control method does not necessarily have to be implemented using the beam cone sintering vehicle.

[0047] like Figure 1-4 As shown, the focusing light cone sintering vehicle includes a mirror frame 1, a rotation angle and pitch angle adjustment mechanism 2, a micro-concave mirror 3, a visual recognition camera 4 and a control unit 5.

[0048] The mirror frame 1 is used to install the rotation and pitch angle adjustment mechanism 2 and the micro-concave mirror 3, and has a hollow area in the middle, which is the channel for the light beam 6 reflected by the micro-concave mirror 3 to pass through. Therefore, there is no other solid structure below the hollow area. Exemplarily, the mirror frame 1 is a rectangular frame, such as a square frame or a rectangular frame; of course, the mirror frame 1 can also be a regular hexagonal frame, a circular frame, an elliptical frame or a triangular frame, etc.

[0049] The turning angle and pitch angle adjustment mechanism 2 is a combination of a turning angle adjustment mechanism and a pitch angle adjustment mechanism, and belongs to the prior art. Among them, the turning angle refers to the angle of rotation when the vertical axis (Z axis) is used as the rotation axis for angle adjustment, and the pitch angle refers to the angle of rotation when the horizontal axis (X axis or Y axis) is used as the rotation axis for angle adjustment. The turning angle and pitch angle adjustment mechanism 2 are arranged in the hollow area, and the entire hollow area is covered in the form of a matrix distribution. There are gaps between adjacent turning angles and pitch angle adjustment mechanisms 2 so that the reflection of the micro-concave mirror 3 can smoothly reach the sand surface downward. Exemplarily, the adjustment of the turning angle and the pitch angle is driven by a servo motor so that the desired adjustment accuracy can be achieved; of course, other forms of angle adjustment mechanisms can also be used, which will not be repeated here. Exemplarily, criss-cross support rods are arranged in the hollow area of ​​the mirror frame 1. The support rods should have a certain strength so as to be able to bear the weight of the angle and pitch angle adjustment mechanism 2 and the micro-concave mirror 3, but the cross-sectional area should not be too large to avoid affecting the emission light path. The angle and pitch angle adjustment mechanism 2 is installed on the support rods.

[0050] The micro-concave mirror 3 is used to reflect sunlight, and preferably a mirror with less light loss is used. There are multiple micro-concave mirrors 3 and the angle adjustment mechanism 2, and multiple micro-concave mirrors 3 are arranged on multiple angle adjustment mechanisms 2 in a one-to-one correspondence.

[0051] The visual recognition camera 4 has a virtual ruler and a virtual cross reference point, which is used to capture images and form a virtual ruler and a virtual cross reference point on the image. The visual recognition camera 4 is set under the mirror frame 1, but does not appear on the route of the emission light beam 6; illustratively, the visual recognition camera 4 is installed under the support rod, or under the frame of the rectangular frame. The visual recognition camera 4 is used to provide the control unit 5 with images and virtual cross reference points.

[0052] The control unit 5 is electrically connected to the rotation angle and pitch angle adjustment mechanism 2 and the visual recognition camera 4, and is used to: control the rotation angle and pitch angle adjustment mechanism 2, adjust the rotation angle and pitch angle of the micro-concave mirror 3, make the light spots reflected by the multiple micro-concave mirrors 3 converge into one point on the sand surface to form a light spot, and control the movement of the light spot. The temperature of the sand surface where the light spot is located will rise, the sand will melt, and the light spot will slowly move after melting. The melted sand in the area away will cool and solidify into a sintering point. Through the slow movement of the light spot, the sand is continuously melted and solidified, so that the sintering points are connected into a linear sintering belt, and the light spot is moved vertically and horizontally to form a grid-like sintering belt.

[0053] The origin is calibrated before leaving the factory; when a preset number of scattered light spots appear outside the light spot, the origin is calibrated again. Among them, the origin calibration includes: the visual recognition camera 4 collects the image of the sand surface below and marks a virtual cross reference point in the collected image; controls a certain rotation angle and pitch angle adjustment mechanism 2 to adjust the rotation angle and pitch angle of the micro-concave mirror 3 thereon, so that the reflected light beam 6 is irradiated on the sand surface to form a light spot and move the light spot; when the light spot coincides with the virtual cross reference point in the image collected by the visual recognition camera 4, stops adjusting the rotation angle and pitch angle of the current micro-concave mirror 3, and records the current rotation angle and pitch angle as the origin value, which is both the origin value of the rotation angle and pitch angle adjustment mechanism 2 and the origin value of the micro-concave mirror 3; after the current micro-concave mirror 3 is calibrated, the control unit 5 controls the corresponding rotation angle and pitch angle adjustment mechanism 2 to make the current micro-concave mirror 3 tilt upward to avoid affecting the determination process and accuracy of the origin values ​​of other micro-concave mirrors 3; during the origin calibration process, each of the micro-concave mirrors is performed in turn.

[0054] When in use, the control unit 5 controls the actions of each turning angle and pitch angle adjustment mechanism 2 according to the programmed program, so that the light reflected by each micro-concave mirror 3 converges to a point on the sand surface to form a light spot; when controlling the movement of the light spot, the light spot is moved along the X-axis or Y-axis according to the programming; the control unit 5 controls the reflected light beam 6 of the micro-concave mirror 3 to form a light spot on the sand surface according to the program, which is essentially a process of resetting the origin. Afterwards, according to the moving distance, the turning angle difference and the pitch angle difference that each micro-concave mirror 3 should rotate are calculated, and according to the calculation results, the action of the turning angle and pitch angle adjustment mechanism 2 is controlled, so that the turning angle and pitch angle of the micro-concave mirror 3 are adjusted to move the light spot. Generally, hundreds to thousands of micro-concave mirrors 3 are used to reflect sunlight to form a light spot so as to reach a temperature that can melt the sand. Exemplarily, the control unit 5 uses a microprocessor, a PLC programmable controller, etc. In the programming, the plane X-axis and Y-axis data of the square-shaped fusion belt shape formed by the light spot irradiation will be preset. For example, suppose that before the operation, the plane diagram of the operation area is preset as a 15m*15m square-shaped fusion belt, and a fusion belt is operated every one meter in the horizontal and vertical directions (as shown below), so as to set the X-axis and Y-axis data. All micro-concave mirrors use this data as coordinates, focus on one point and start to fuse the sand, and move forward 15 meters like a ballpoint pen sliding on paper to form a 15-meter fusion belt, and then repeat the previous action at a horizontal interval of 1 meter, and so on, until the operation is completed with a total of 16 longitudinal fusion belts, and then start from the initial micro-concave mirror focus point of the operation, move 15 meters horizontally to form a 15-meter fusion belt, and then repeat the previous action at a vertical interval of 1 meter, and so on, until the operation is completed with 16 transverse fusion belts.

[0055] In this embodiment, the beam cone sintering vehicle includes multiple visual recognition cameras 4; or the beam cone sintering vehicle includes multiple laser radars 7 and multiple visual recognition cameras 4, and the laser radars 7 are electrically connected to the control unit 5; the multiple visual recognition cameras 4 or the combination of multiple laser radars 7 and multiple visual recognition cameras 4 are used to construct a three-dimensional terrain model of the sand surface. The control unit 5 controls the turning angle and pitch angle adjustment mechanism 2 to adjust the turning angle and pitch angle of the micro-concave mirror 3 based on the three-dimensional terrain model constructed by the multiple visual recognition cameras 4 or the multiple laser radars 7 and the multiple visual recognition cameras 4. Due to the uneven surface of the desert, when the reflected light spot is irradiated on a higher ground, the light spot will become larger, and vice versa. After the three-dimensional terrain model is constructed, the control unit will add the data information of the Z axis under the premise that the preset X-axis and Y-axis data remain unchanged, and superimpose and calculate the angle of each micro-concave mirror to adjust the height of the focus point to correspond to the terrain with height changes.

[0056] In this embodiment, the beam cone sintering vehicle further includes a light sensor 8, which is used to monitor light intensity and light angle. The light sensor 8 is electrically connected to the control unit 5. The control unit 5 divides all the micro-concave mirrors 3 on the mirror frame 1 into one or more sand melting units based on the light intensity, and each sand melting unit forms a light spot. In this way, multiple sintering points can be formed at one time, thereby improving work efficiency. Exemplarily, the light sensor 8 is arranged on the roof of the vehicle, receives information such as light intensity and light angle, and transmits a signal to the control unit 5. After receiving the signal, the control unit 5 controls the mobilization of the corresponding concave mirror module, adjusts the mirror angle, and controls the movement of the vehicle to ensure the best melting effect; when the light is strong, a small number of micro-concave mirrors 3 are mobilized to reflect sunlight and converge to a point to reach a suitable temperature, so that the mirror matrix can be distributed into multiple groups to work simultaneously and melt the sand quickly; but when the light is weak, multiple micro-concave mirrors 3 are required to reflect sunlight and converge to a point to ensure that the melting temperature is reached, and the melting speed is therefore slowed down, and the number of mirror matrix groupings will be reduced.

[0057] In this embodiment, the beam cone smelting vehicle further includes a temperature sensor 9, which is used to monitor the temperature of the sand surface where the light spot is located. The temperature sensor 9 is electrically connected to the control unit 5. The control unit 5 controls the movement and movement speed of the light spot based on the temperature monitored by the temperature sensor 9. Generally, the temperature of the area where the light spot is located needs to be much higher than the melting point of the sand before the light spot is moved. The movement speed of the light spot is relatively slow so that the sand in the area covered by it can be melted during the movement. The temperature sensor 9 monitors the temperature information of the sand surface, especially the temperature information at the light spot, to assist the controller in correcting the control data. Exemplarily, the temperature sensor 9 adopts a visual infrared sensor, and of course other types of sensors for monitoring temperature can also be used.

[0058] In this embodiment, a plurality of power telescopic support mechanisms 10 are provided at the bottom edge of the mirror frame 1, and the power telescopic support mechanisms 10 are electrically connected to the control unit 5; the control unit 5 controls the extension and retraction of the power telescopic support mechanism 10, and the power telescopic support mechanism 10 is mainly used to adapt to the uneven terrain of the desert surface, so that the mirror frame 1 can be adjusted to the required tilt angle according to the needs. Exemplarily, the power telescopic support mechanism 10 adopts an electric telescopic column or a hydraulic telescopic column, which is an existing device and the specific structure is not introduced; the control unit 5 controls the motor of the electric telescopic column to operate, or controls the solenoid valve of the hydraulic telescopic column to operate, so as to realize the extension and retraction of the column body, thereby adjusting the angle of the mirror frame 1. Exemplarily, the mirror frame 1 is parallel to the horizontal plane. Exemplarily, a power telescopic support mechanism 10 is installed at the bottom of each of the four corners of the rectangular frame.

[0059] In this embodiment, a moving mechanism 11 is provided at the bottom of the power telescopic support mechanism 10, and the moving mechanism 11 is electrically connected to the control unit 5; the control unit 5 controls the start and stop of the moving mechanism 11 to move the mirror frame 1. The sintering vehicle is in a stationary state during the sand melting operation. The control unit 5 controls the turning angle and pitch angle adjustment mechanism 2 to adjust the turning angle and pitch angle of the micro-concave mirror 3 to achieve the movement of the light spot, thereby training the sintering point into a shorter sintering belt; when the sand surface where the sintering vehicle is located completes all the operations, the sintering vehicle will move a body position, stop and continue the next round of operations; in this way, after moving vertically and horizontally, a grid-shaped sintering zone is formed. Exemplarily, the moving mechanism 11 adopts a crawler structure driven by a motor, which will not sink in the desert or sandy road surface, wherein the crawler structure driven by the motor is an existing structure, and its structure will not be repeated; the moving mechanism 11 can also adopt a wheeled structure, but more wheels are required to avoid getting stuck.

[0060] In this embodiment, the beam cone fusion vehicle further includes a solar panel 12 and a power storage unit 13. The solar panel 12 is arranged around the mirror frame 1. The solar panel 12 is electrically connected to the power storage unit 13. The power storage unit 13 is electrically connected to the control unit 5. The control unit 5 controls the on and off of the circuits of various electrical appliances. Exemplarily, the solar panel 12 is installed on the side of the mirror frame 1 through a bracket with an angle adjustment function, wherein the bracket with an angle adjustment function adopts an existing one, and therefore its structure is not described in detail. Exemplarily, the power storage unit 13 adopts a lithium battery pack, which is installed on the side of the mirror frame 1 and is located below the solar panel 12 so as not to block the solar panel 12.

[0061] The structure of the focusing light cone sintering vehicle provided in this embodiment is not limited to the above structure and will not be introduced here.

[0062] The method for sand treatment by sintering a concentrated light cone comprises the following steps:

[0063] A plurality of micro-concave mirrors are arranged above the sand surface;

[0064] Adjust the rotation angle and pitch angle of each micro-concave mirror so that the solar beams reflected by multiple micro-concave mirrors converge at one point to form a light spot;

[0065] The temperature of the sand surface where the light spot is irradiated rises rapidly, and after a period of time, the sand grains on the sand surface where the light spot is located melt;

[0066] Move the light spot and heat the sand in the new area where the light spot is located;

[0067] The molten sand in the area where the light spot is removed cools and solidifies into sintering points;

[0068] As the light spot moves, the continuously formed sintering points are connected into a sintering belt.

[0069] As the focused light spot (light spot) moves longitudinally and transversely, the sand is sintered into a glazed belt, and with the help of the mobility provided by the moving mechanism 11, a square-shaped hard shell (similar to a grass grid or a stone grid) is eventually accumulated on the desert surface to achieve a sand control effect.

[0070] In this embodiment, the method for sand control by beam cone sintering further includes: performing an initial origin calibration on each of the micro-concave mirrors, and re-calibrating the origin when a preset number or proportion of light spots appear outside the light spot;

[0071] Among them, the origin calibration includes: controlling the rotation angle and pitch angle adjustment mechanism, adjusting the rotation angle and pitch angle of the micro-concave mirror, so that the light spot reflected by the micro-concave mirror appears in the image collected by the visual recognition camera, and aligning the light spot appearing in the collected image with the virtual cross reference point, recording the rotation angle and pitch angle of the micro-concave mirror at this time as the origin value, and the origin value is also the origin value of the rotation angle and pitch angle adjustment mechanism; after the current micro-concave mirror calibration is completed, the control unit controls the corresponding rotation angle and pitch angle adjustment mechanism to make the current micro-concave mirror tilt upward; during the origin calibration process, each micro-concave mirror is performed in turn.

[0072] Generally, when checking the origin, all the micro-concave mirrors 3 are set upwards, so as to ensure that the reflected light beam 6 will not shine on the ground, avoiding affecting the determination of the origin value. During the calibration work, the light sensor 8 receives the sunlight position (i.e. monitors the light angle) to assist in determining the position where the reflected light spot should shine.

[0073] During the operation, the visual recognition camera 4 will observe the state of the reflected light spot in real time. When other scattered light spots appear besides the target light spot, it means that the origin of some micro-concave mirrors 3 is offset. When the number of offset lenses reaches a certain level, the motors of all micro-concave mirrors 3 are re-calibrated for the origin to ensure the focusing effect and sintering temperature, etc.

[0074] In this embodiment, the method for controlling sand by beam cone sintering further includes: constructing a three-dimensional terrain model based on multiple visual recognition cameras or multiple laser radars and multiple visual recognition cameras, controlling the turning angle and pitch angle adjustment mechanism based on the three-dimensional terrain model, adjusting the turning angle and pitch angle of the micro-concave mirror, and thus adjusting the height of the light spot to correspond to the terrain with height changes. Since the surface of the desert is uneven, when the reflected light spot is irradiated on a higher ground, the light spot will become larger, and vice versa, the light spot will become smaller. Through three-dimensional modeling, the auxiliary control unit 5 controls the micro-concave mirror 3 to adjust the angle according to the terrain information, so that the light spot can be adjusted to the most suitable size under different ground conditions.

[0075] In this embodiment, the light intensity is monitored, and all the micro-concave mirrors 3 are converted into one or more sand melting units based on the light intensity. Each sand melting unit will form a light spot for melting sand. Generally, hundreds to thousands of micro-concave mirrors 3 are set on the beam cone melting vehicle. For example, 5,000 mirrors are set, arranged vertically and horizontally into 100 columns and 50 rows. During the operation of the equipment, according to the intensity of sunlight at that time, the 5,000 mirrors are divided into two groups for joint operation, that is, each group of 50 columns and 50 rows, a total of 2,500 mirrors, need to reflect sunlight and converge to the same point together to ensure that the energy received by the point is sufficient to reach the temperature for melting sand. Each mirror needs to be adjusted to a different angle due to its own position, and continuously receives the position change information of the sun and the convergence point, and makes compensation adjustments to the lens angle. Exemplarily, the size of the mirror frame 1 required for the above-mentioned arrangement of the 5,000 mirror matrix is ​​about 20 meters * 20 meters, the length of the power telescopic support mechanism 10 is up to about 20 meters, the shortest contracted length is about 10 meters, and the lens size is about 15cm * 30cm.

[0076] In this embodiment, the method for sand control by beam cone smelting also includes: real-time monitoring of the temperature of the ground where the light spot is located, and controlling the movement and speed of the light spot based on the monitored temperature. The light spot starts to move after the sand surface temperature corresponding to the area where the light spot is first formed is much higher than the melting point of the sand, and the movement process is very slow, ensuring that the sand in the area irradiated by the light spot (referring to the sand grains on the surface) can be melted during the movement process.

[0077] In this embodiment, the method for sand control by beam-cone sintering further includes: controlling each power telescopic support mechanism to adjust the angle of the mirror frame.

[0078] In this embodiment, the method for sand control by using concentrated light cone sintering further includes: after sintering one area, controlling the start and stop of the moving unit mechanism to move the concentrated light cone sintering vehicle.

[0079] A plurality of micro-concave mirrors 3 with different rotation angles and different pitch angles are used to focus sunlight on a point (i.e., a light spot) on the sand surface, so that the sand grains on the sand surface where the light spot is located are heated until they melt, and then the light spot is moved, and the melted sand grains in the area where the light spot is moved cool and solidify to form a sintering point. After the light spot moves, the sand grains in the new area are heated, so that continuous sintering points form a sintering belt, thereby forming a sand barrier, achieving the purpose of solidifying and controlling the desert; the device (beam light cone sintering vehicle) and method (beam light cone sintering sand control method) utilize natural resources to control natural problems, with excellent results, no destructiveness to the ecological environment, automatic operation of the equipment without manpower consumption, convenient maintenance, low cost, energy saving and high efficiency.

[0080] This method uses the power of nature to fight against nature, has no energy consumption, does not produce pollution emissions, reduces the input of additional material resources, has a good effect of melting sand, and forms a hard shell after solidification to cover the surface of the desert, reduce wind and dust, and block the migration of sand. Therefore, it can effectively improve the water storage capacity of the desert and achieve the purpose of desert control. The equipment runs automatically and is easy to maintain, thus saving labor costs.

[0081] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
