Description

Technical Field

[0001] The present invention relates to the technical field of land resource management, and in particular to a method for collecting data on land resources. Background Art

[0002] Data collection of land resources refers to the collection and recording of various data and information related to land resources for analysis, management and decision-making. The types of data collected are divided into the following categories according to needs: land use status, land cover, soil type, topography, climatic conditions, hydrological information, land ownership, population and socio-economic data, and environmental quality. The data collection method can obtain detailed land information through field surveys and sample collection, or use drones for low-altitude aerial photography to obtain high-resolution land images.

[0003] After searching, the patent with application number CN202211175514.1 discloses a data collection device for land resources, including a carrying platform, a mounting bracket, a mounting cylinder, a mounting plate, a servo motor, and a land surveying instrument. The lower end face of the carrying platform is rotatably sleeved with a gear ring, and the gear ring is provided with an array of positioning bolt holes. The upper end face array of the carrying platform is provided with a slot, and each of the lower inner walls of the slot is penetrated by a rotating sleeve with a screw rod, and the sliding sleeve in the slot is provided with a slide plate, the screw rod is fixedly sleeved with a first gear at one end below the carrying platform, and the first gear is meshingly connected with the gear ring, the slide plate threaded sleeve is arranged on the outer side of the screw rod in each slot, and the upper end face array of the slide plate is provided with an opening.

[0004] In this case, the multi-dimensional use of the equipment on the ground and in the air is achieved through the cooperation of the carrying platform and the mounting bracket; at the same time, the flexibility of the equipment in specific use is greatly improved by rotating the card slot and the limit card block in conjunction with the card sleeve limit, as well as the interference between the vertical plate and the lower inner wall of the card slot. It also facilitates modular and efficient installation and use, greatly improving the functionality of the equipment.

[0005] However, this case lacks the function of sample collection. Sample collection, as an important step in on-site investigation, directly affects the collection results of land information.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] S2. Field survey: When the operator reaches the area near the collection point, the control device fine-tunes the position and moves to the precise coordinates of the collection point.

[0038] S3, sample collection: After the device is positioned to the precise coordinates of the collection point, the collection component is used to complete the ground breaking operation and collect soil samples. At the same time, the storage component rises synchronously to facilitate personnel to carry out equipment picking operations;

[0039] S4. Sample storage: The collected samples are stored inside the device using a limiting mechanism to complete the automatic collection operation of the device, thereby meeting the needs of multiple collections during field surveys, and synchronously controlling the storage components to ensure that the center of gravity of the device is lower than the geometric height when it is moving, thereby preventing the device from tipping over. Embodiment 2:

[0040] See also Figures 1 to 4 This embodiment further explains Example 1, a land resource data collection method, including a protection frame 1 that provides a framework support for the entire device, arc grooves 11 are opened at the center positions of both sides of the protection frame 1, and hooks 12 are fixedly connected to the tops of the outer contours of both ends of the protection frame 1. Four hooks 12 are provided and are mirror-symmetrically distributed along the central axis of the protection frame 1. The bottoms of both ends of the protection frame 1 are penetrated and limitedly rotated by a traveling shaft 13, and the axial ends of the traveling shaft 13 are fixedly connected to traveling wheels 14. A balancing component for maintaining the center of gravity balance of the device and controlling the working state of the device is provided inside the protection frame 1.

[0041] The balancing assembly includes a balancing plate 2, and positioning rods 21 are fixedly connected to both sides of the balancing plate 2. The end of the positioning rod 21 away from the balancing plate 2 is penetrated by and rotatably connected to a positioning shaft 22. The two axial ends of the positioning shaft 22 are limitedly rotatably connected to guide wheels 23. The guide wheels 23 are located inside the arc groove 11 and are limitedly slidably connected to the arc groove 11. An annular seat 24 is penetrated at the center of the top end of the balancing plate 2 and is limitedly rotatably connected. A driving roller 25 is fixedly connected to the top end of the annular seat 24. A collecting assembly for breaking the ground is arranged inside the driving roller 25.

[0042] The travel axis 13 is driven by an external motor and the motor is electrically connected to an external remote control device via a wireless signal. The annular seat 24 is driven by an external motor and is fixedly connected to the output shaft of the motor. Four positioning rods 21 are provided and are distributed in a mirror-symmetrical manner along the central axis of the balance board 2.

[0043] In the present invention, the protective frame 1 is used as the main frame structure of the device to provide support for the device, the arc groove 11 and the balance component cooperate to maintain the horizontal state of the structure and equipment inside the device, the device is fixed to the bottom of the drone through the hook 12 to realize the aerial photography function, and the travel axis 13 is controlled and driven by an external remote control device to drive the travel wheel 14 to rotate to realize the movement and fine-tuning of the device.

[0044] Furthermore, when the device travels to a bumpy road section, the protection frame 1 is in a tilted state and the guide wheel 23 slides relatively inside the arc groove 11, and the guide wheel 23, the positioning shaft 22, the positioning rod 21 and the balance plate 2 continue to maintain a nearly horizontal state under force balance, thereby reducing the amplitude of position changes of subsequent storage components and collection components, and minimizing the damage caused by bumps during the movement of the device and the collision of structures and equipment inside the device.

[0045] When the device moves to the precise coordinates of the collection point, the motor starts working and drives the annular seat 24 and the driving roller 25 to rotate synchronously. The annular seat 24 controls the collection component to start working and the driving roller 25 further adjusts the height of the storage component to make the storage component rise to meet the needs of personnel to take the surveying equipment. Embodiment three:

[0046] See also Figures 5 and 6This embodiment further explains the second embodiment. The collection component includes a spiral tooth 3, which penetrates and is screwed to the inner contour of the driving roller 25. The axis of the spiral tooth 3 is penetrated and fixedly connected with a collection tube 31. The bottom end of the spiral tooth 3 penetrates and is screwed to the center of the balance plate 2. The bottom end of the collection tube 31 is penetrated and limitedly rotated with an annular baffle 32. A fixing ring 33 is fixedly connected to the inner contour of the collection tube 31 near the bottom end. A blocking roller 34 is fixedly connected to the outer contour of the bottom end of the fixing ring 33. There are multiple blocking rollers 34 distributed in a circular array along the axis of the fixed ring 33. The bottom end of the blocking roller 34 is fixedly connected to a limiting ring 35. The limiting ring 35 is slidingly connected to the inner contour of the collection tube 31. A guide rod 36 is fixedly connected to the outer contour of the limiting ring 35. The bottom end of the collection tube 31 is provided with a semicircular slideway adapted to the movement of the guide rod 36. The bottom end of the guide rod 36 passes through and is transmission-connected to the annular baffle 32. The outer contour of the driving roller 25 is provided with a storage component for storing data acquisition equipment and adjusting the height of the device.

[0047] The bottom ends of the collection tube 31 and the limiting ring 35 are both set with sharp chamfers, the annular baffle 32 is connected to the semicircular slideway at the bottom end of the collection tube 31 for limited rotation, the blocking roller 34 is made of flexible material, and the rotation direction of the spiral teeth 3 is set to be the same as that of the driving roller 25.

[0048] Along with the rotation of the driving roller 25, the spiral teeth 3 and the collection tube 31 rotate synchronously, and the bottom end of the spiral teeth 3 is screwed to the balance plate 2 and the balance plate 2 is in a stationary state, so that the rotation of the spiral teeth 3 causes the spiral teeth 3 to drive the collection tube 31 to extend downward from the inside of the driving roller 25.

[0049] When the spiral teeth 3 and the collection tube 31 extend downward, the guide rod 36 comes into contact with the ground and is squeezed by the friction of the ground so that the guide rod 36 moves to the extreme position of the semicircular slide at the bottom end of the collection tube 31. At this time, the collection assembly is in the open state, and the sharp chamfers at the bottom ends of the collection tube 31 and the limit ring 35 come into contact with the ground to perform ground breaking operations.

[0050] As the earth-breaking operation proceeds, soil samples are collected inside the collection tube 31. When the spiral teeth 3 and the collection tube 31 are lowered to the limit position, the annular seat 24 rotates in the opposite direction. It can be seen from the above process that at this time, the annular seat 24 drives the spiral teeth 3 and the collection tube 31 to rise synchronously, and the guide rod 36 causes relative rotation between the initial guide rod 36 and the collection tube 31 under the friction of the soil, and the guide rod 36 moves along the semicircular slide at the bottom end of the collection tube 31 to the limit position at the other end.

[0051] At this time, the guide rod 36 drives the limit ring 35 to rotate synchronously, and the fixed ring 33 rotates synchronously with the collection tube 31, thereby causing the blocking roller 34 to bend and causing the bottom end of the collection tube 31 to be blocked to prevent the soil sample from falling. The collected soil sample is stored inside the collection tube 31.

[0052] During the rotation and resetting of the guide rod 36 , the guide rod 36 drives the annular baffle 32 to move synchronously, and the annular baffle 32 fills the semicircular slide at the bottom of the collection tube 31 to prevent soil particles from accumulating in the semicircular slide and causing the movement of the guide rod 36 to be obstructed. Embodiment 4:

[0053] See also Figures 7 and 8 This embodiment further explains the third embodiment. The storage assembly includes a storage frame 4. Two storage frames 4 are provided and are distributed along the central axis of the balance plate 2 in a mirror-symmetrical manner. A connecting rod 41 is fixedly connected between the storage frames 4. A threaded groove 42 is provided at the contact position between the storage frame 4 and the driving roller 25. A limiting mechanism for storing soil samples and positioning and fixing the device is provided at the bottom end of the protection frame 1.

[0054] The limiting mechanism includes a storage frame 5, and one end of the storage frame 5 close to the protection frame 1 is fixedly connected to a steering shaft 51, and the steering shaft 51 passes through and is connected to the inner contour of the bottom end of the protection frame 1 for limited rotation. A tension spring 52 is arranged on the outer contour of the top end of the storage frame 5, and one end of the tension spring 52 away from the steering shaft 51 is fixedly connected to the center of the inner contour of the protection frame 1, and a guide plate 53 is fixedly connected to the center of the top end of the storage frame 5.

[0055] The outer contour of the top end of the guide plate 53 is set as a single slope with an inclination angle of thirty degrees, and the tension spring 52 is initially in a compressed state.

[0056] When the collection operation is in progress, the rotation of the annular seat 24 synchronously drives the threaded groove 42 and the storage frame 4 to rise. At this time, the overall height of the storage frame 4 is raised to facilitate personnel to take out the surveying equipment stored in the storage frame 4; and with the completion of the collection operation, the annular seat 24 rotates in the opposite direction to drive the height of the storage frame 4 to drop. At this time, the storage assembly is located inside the protective frame 1 so that the center of gravity of the device is lower than the geometric height, thereby minimizing the probability of the device tipping over. The two storage frames 4 are connected and fixed by the connecting rod 41 to ensure the synchronous lifting and lowering of the two storage frames 4.

[0057] While the spiral teeth 3 and the collection tube 31 extend downward, the bottom end of the collection tube 31 squeezes the storage frame 5 and causes the storage frame 5 to deflect along the steering shaft 51 and the tension spring 52 to be stretched. With the further deflection of the steering shaft 51, when the steering shaft 51 contacts and squeezes the ground, the protection frame 1 tilts at a small angle under the support of the steering shaft 51. At this time, the steering shaft 51 is inserted into the ground to achieve the positioning and fixation of the device.

[0058] During the upward retraction of the spiral teeth 3 and the collection tube 31, the spiral teeth 3 gradually come into contact with the storage frame 5. At this time, the storage frame 5 begins to reset under the action of the spiral teeth 3 and the tension spring 52. Further, during the resetting process of the storage frame 5, the storage frame 5 comes into contact with the guide rod 36. At this time, the storage frame 5 squeezes the guide rod 36 to reset the guide rod 36 along the semicircular slide at the bottom end of the collection tube 31. The resetting of the guide rod 36 causes the bending state of the fixing ring 33 to be released, and the blockage of the bottom end of the collection tube 31 by the fixing ring 33 disappears. At this time, the soil sample collected in the collection tube 31 falls to the upper surface of the storage frame 5, and the soil sample passes through the inclined surface of the guide plate 53 and is collected between the storage frame 5 and the guide plate 53. The single inclined surface setting of the guide plate 53 ensures that the collected soil sample will not slide when the limiting mechanism fixes the device, thereby completing the storage of the soil sample.

[0059] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
