Description

Technical Field

[0001] This invention specifically relates to a portable sand barrier grid micro-topography change measurement device, belonging to the field of wind and sand physics and desert geomorphological environment monitoring technology. Background Technology

[0002] Sand barriers, also known as mechanical sand barriers, are one of the most common and effective engineering measures in the control of shifting sands, and are widely used in desertified areas of my country. They are a collection of various natural and synthetic solid materials (such as straw, branches, crop stalks, stones, fiber nets, geotextiles, etc.) placed on the sand surface to prevent wind erosion and sand fixation. Their basic principle is to increase ground roughness, control the direction, speed, and structure of windblown sand, and change the surface erosion and deposition, thereby altering the wind force and landform. Due to the uncertainty of wind direction in desertified areas, sand barriers are mostly set up in a grid shape to curb the hazards of windblown sand from different directions. Their size depends on factors such as barrier height, material properties, permeability coefficient, and local wind speed. In practice, the most commonly used straw sand barriers are generally 1 meter × 1 meter, while willow sand barriers are 2 meters × 2 meters or 3 meters × 3 meters. The sizes of sand barriers made of other materials are not standardized. In reality, given a fixed material for sand barriers, their specifications are the most significant limiting factor in their effectiveness and benefits in preventing wind erosion and fixing sand. While excessively small barriers may offer good windbreak and sand-fixing effects, they waste materials and increase installation costs; conversely, excessively large barriers, while saving materials and reducing installation costs, significantly diminish their effectiveness. Therefore, determining the optimal layout specifications for sand barriers of different materials and in different desertified regions is crucial. Besides wind field observation, simulation, and empirical estimation, monitoring changes in the micro-topography of existing sand barriers and summarizing these changes to propose reasonable layout specifications is a vital approach. From the perspective of sand fixation and transport, the ideal state for sand barriers is non-accumulated transport of sand, meaning the micro-topography within the barrier remains constant; while from the perspective of sand blocking and transport, the ideal state is accumulated transport of sand, meaning the micro-topography within the barrier increases positively. Furthermore, in the process of sand control and desertification prevention, sand barriers are only a temporary and preliminary defensive measure; long-term and permanent measures ultimately rely on vegetation systems. In this way, if we can accurately predict and grasp the changes in ground micro-topography and erosion within various sand barrier grids, we can determine reasonable locations for planting trees and grass in the early stages within the barrier, so as to avoid the damage to seedlings caused by wind erosion and sand burial. Based on the above objectives, this invention proposes a portable sand barrier grid micro-topographic change measurement device. Through regular monitoring and calculation, it can grasp the micro-topographic change patterns within various sand barrier grids, providing support and services for optimizing the layout of sand barriers and scientific afforestation and grass planting. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a portable sand barrier grid micro-topography change measurement device, so as to achieve the goals of easy portability and accurate measurement.

[0004] A portable sand barrier grid micro-topography change measurement device includes a portable component (100). The portable component (100) includes four support plates (101) and several probe rods (103). The four support plates (101) are arranged horizontally and are hinged together by three-part hinges.

The bottom of the probe rods (103) is fitted with a ground plug (106). The outer wall of the probe rods (103) is provided with scale values.

[0005] Furthermore, the outer wall of the measuring rod is provided with an anti-slip groove, which is arranged in a ring. Furthermore, the dimensions of the first threaded groove are the same as the dimensions of the first threaded post.

[0006] Furthermore, the portable component includes a storage box, the inner wall of which is fitted with a partition, and the top of which is hinged to a cover plate, with a handle fitted on one side of the cover plate.

[0007] Furthermore, two shoulder straps are installed on one side of the storage box, and belt buckles are installed on the shoulder straps.

[0008] A portable device for measuring micro-topographical changes in a sand barrier grid, including a leveling component; The leveling assembly (200) includes four housings (201) and four rotating rods (211). One side of the housing (201) is hinged to the bottom of the two edge support plates (101) via a hinge shaft. One end of the housing (201) is rotatably connected to a rotating plate (205) via a rotating shaft. A threaded post (206) is installed on the side of the rotating plate (205) away from the housing (201). A motor (204) is installed on the inner wall of the housing (201). The output end of the motor (204) is fixedly connected to the bearing of the rotating plate (205) via a connecting rod. A threaded groove (213) is provided on the top of the rotating rod (211). A spiral drill bit (214) is installed on the bottom of the rotating rod (211). An anti-slip groove (212) is provided on the outer wall of the rotating rod (211). The anti-slip groove (212) is arranged in a ring.

[0009] Furthermore, the dimensions of the second threaded groove are the same as the dimensions of the second threaded post.

[0010] Furthermore, a control switch is installed on one side of the housing.

[0011] Furthermore, two magnetic blocks are installed at the bottom of the two support plates on the edge, and a magnetic groove is provided at one end of the housing, the size of which matches the size of the magnetic groove and the magnetic blocks.

[0012] Furthermore, a semi-circular connecting groove is provided on the top of each of the two middle support plates, and a circular connecting block is installed on the two semi-circular connecting grooves. A level is installed on the top of the circular connecting block. A storage battery is installed on the inner side wall of the housing, and the storage battery is electrically connected to the motor and the control switch respectively.

[0013] Beneficial effects: I. This invention, through the setting of support plates and measuring rods, with four support plates hinged together to form a foldable grid frame, combined with a detachable scale measuring rod at the bottom, achieves accurate measurement of the surface elevation of the entire area within the sand barrier grid. The scale value of the measuring rod directly reflects the change in erosion thickness. The matching design of the threaded groove and the threaded post ensures the vertical stability of the measuring rod, avoiding wind vibration errors. Compared with manual point-by-point measurement, dozens of points within the grid can be obtained in a single operation, effectively improving efficiency. Moreover, the data has strict spatial correlation, providing high-resolution basic data for analyzing the three-dimensional movement law of wind and sand flow. Second, this invention, through the arrangement of the auger drill bit and motor, has four housings distributed at the four corners of the unfolded support plate. By controlling the switch to start the motor, the rotating plate is driven to press down the threaded column two, so that the auger drill bit at the bottom of the rotating rod penetrates into the stable stratum. With the use of a level, by controlling the rotation of a single motor, the device is kept in a horizontal state, which improves the convenience of the device. Third, through the setting of the storage box, the four shells can rotate along the hinge axis and fit tightly against the bottom of the support plate. The four support plates can be folded synchronously along the hinge axis into a compact rectangular structure. The four shells are distributed on both sides of the rectangular structure. After folding, they match the rectangular inner cavity of the storage box. The support plate is separated from the measuring rod, rotating rod and spiral drill bit by the partition plate to avoid collision and damage to the device, thereby improving the portability of the device.

[0027] Working principle: The storage box 107 is made of rotomolded high-density polyethylene with built-in EVA foam. The folded support plate 101 assembly is placed on one side of the box, and the measuring rod 103 and four rotating rods 211 are placed on the other side. It is carried by shoulder straps 111, allowing a single person to carry the entire equipment. Select the center area of ​​the target sand barrier grid, clear the surface sand to a stable sand layer, ensuring the representative topography of the measurement surface. Remove the folded device from the storage box 107. The four support plates 101 unfold into a square shape via three-link hinges, with the bottom of the support plates 101 facing upwards. The threaded post at the top of the measuring rod 103... 104 is screwed into the threaded groove 102 of the housing 201, so that the probe rod 103 is vertically fixed to the bottom of the support plate 101. The four housings 201 at the bottom of the support plate 101 are rotated upward by hinges. The magnetic blocks 203 at the ends of the housings 201 ensure that the housings 201 and the support plate 101 maintain a stable vertical state. The threaded post 206 at the top of the housing 201 is screwed into the threaded groove 213 of the rotating rod 211. The design of the anti-slip groove 105 and the anti-slip groove 212 increases the friction and ensures stable grip in sandy environments. The support frame is flipped so that the probe rod 103 faces downwards, and the horizontal... The level 209 is installed into the semi-circular connecting groove 215 at the top of the support plate 101. The operator visually observes the position of the bubble on the level 209. If the bubble is significantly off-center, manual initial leveling is performed to bring the bubble into the central area. The motor 204 is then started, and the four sets of auger drill bits 214 are simultaneously driven into the sand layer to the reference depth. At this point, the drill bits provide basic anchoring force, but precise leveling is not achieved. By independently controlling a single motor 204, the corresponding auger drill bit 214 is drilled further down, thus keeping the device level. After leveling, the device is left to stand for three minutes to eliminate mechanical stress. Initial measurements are then taken using a graduated caliper. Each measuring rod... Three readings are taken on the circumference of the drill rod 103. After removing outliers, the average value is taken. After the measurement is completed, the level 209 is removed, the motor 204 is started in reverse mode, and the auger drill bit 214 is raised to detach from the compacted sand layer. The housing 201 is rotated 90 degrees inward along the hinge axis so that the housing 201 is flat against the bottom of the support plate 101. The measuring drill rod 103 and the rotating rod 211 are unscrewed. The sand particles attached to each rod are cleaned immediately after removal and placed into the storage box 107 in sequence. After disassembly, the support plate 101 is folded and put into the storage box 107. The measurement point is returned after 30 days, the leveling process is repeated, and the new value is read.
