Description

Technical Field

[0001] The present invention relates to the technical field of wind and sand prevention, and in particular to a sand storage and blocking structure, a wind and sand monitoring system, a method and a wind and sand prevention system. Background Art

[0002] Sand control projects primarily include sand blocking, sand fixation, and sand transport and diversion projects. Sand blocking is the most crucial component of the entire sand control system, serving as the outermost layer of the system, blocking the flow of wind and sand and protecting the inner layer. Common sand control projects primarily involve the installation of sand barriers, including nylon mesh barriers, concrete barriers, and galvanized aluminum mesh barriers.

[0003] It has been found in research and practice that at present, sand-blocking fences often adopt a linear upright structure with a relatively simple structure and function. The upright linear single structure makes its effective sand storage capacity very limited, and it is easy to reach saturation and lose its sand-blocking function. Usually, in order to achieve the purpose of sand blocking, multiple sand-blocking fences need to be constructed to slow down the movement of wind and sand flow. However, as sand materials gradually accumulate, the sand-blocking fence system will fail one by one. Therefore, more sand-blocking fences need to be constructed, which leads to a continuous increase in the cost of wind and sand prevention projects and a long project cycle. Summary of the Invention

[0004] The present invention provides a sand storage and blocking structure, a wind and sand monitoring system, a method and a wind and sand control system, which are used to solve the defects of the existing technology that the cost of wind and sand control projects continues to increase and the project period is long, thereby avoiding the extension of the project period and reducing the cost of wind and sand control projects, and having good economic benefits.

[0079] Now combined Figures 1 to 14 , various embodiments provided by the present invention are described. It should be understood that the following are merely illustrative embodiments of the present invention and do not constitute any particular limitation to the present invention.

[0080] Example 1

[0081] The present invention provides a sand storage and blocking structure. Figure 1 This is a schematic diagram of the top plan structure of the sand storage and blocking structure provided by the present invention. Figure 2 This is a side cross-sectional structural diagram of the sand storage and blocking structure provided by the present invention, see Figures 1 to 2 The sand storage and blocking structure 100 includes a sand storage body 110 and a sand blocking body 120 .

[0082] The sand storage body 110 is positioned upwind of the sand blocking body 120. That is, the wind direction is along the sand storage body 110 toward the sand blocking body 120, and the wind flows from the sand storage body 110 to the sand blocking body 120. Therefore, a sand accumulation corridor 130 is formed between the sand storage body 110 and the sand blocking body 120. This sand accumulation corridor 130 is used to accumulate sand to prevent the wind from carrying sand to a location downwind of the sand blocking body 120. For example, the width of the sand accumulation corridor 130 can be 8-12 meters.

[0083] Furthermore, the sand storage body 110 includes a first sand storage net 111 and a plurality of sand barrier fences 112. The plurality of sand barrier fences 112 are spaced and arranged in parallel on the side of the first sand storage net 111 away from the sand barrier 120. Each sand barrier fence 112 forms a first predetermined angle with respect to the first sand storage net 111, such that adjacent sand barrier fences 112 and corresponding first sand storage nets 111 form a sand storage compartment 113. Each sand storage compartment 113 is a semi-enclosed compartment open to the upwind direction 001. The first predetermined angle can be set based on wind direction, for example, between 45° and 135°, though this embodiment is not limited thereto.

[0084] In this embodiment, the sand storage chamber 113 is a semi-enclosed space formed by three-sided barrier nets, creating a large wind shadow area within the sand storage chamber 113. Once wind and sand flow enter the sand storage chamber 113, it enters a sedimentation state, thereby achieving the function of sand accumulation and storage. Multiple sand isolation fences 112 form at least one sand storage chamber 113. For example, the sand storage body 110 can include at least three sand storage chambers 113.

[0085] When wind and sand reach the first sand storage net 111, they are blocked by the first sand storage net 111. When the wind has a component along the length of the first sand storage net 111, the sand isolation fence 112 can prevent the lateral movement of the accumulated sand, facilitating subsequent sand clearing. This allows the sand storage and blocking structure 100 to have a good sand blocking efficiency, increase the amount of sand blocked, and increase the sand blocking control range. Moreover, as the sand accumulates, a relatively tall and stable sand blocking structure can be effectively formed, which itself also has a good sand prevention and sand guiding effect.

[0086] Furthermore, the sand blocking body 120 includes a sand blocking net 121, which is arranged in parallel with the first sand storage net 111, forming a double barrier to further block sand and achieve a good sand blocking effect. This combination of the sand storage body 110 and the subsequent sand blocking body 120 conforms to the laws of wind and sand movement and can effectively block sand-blocking materials.

[0087] The sand-storage and sand-blocking structure 100 provided in an embodiment of the present invention forms a double-layer barrier by providing a sand storage body 110 and a sand-blocking body 120, thereby achieving a good sand-blocking effect. Furthermore, the sand storage body 110 includes a first sand-storage net 111 and a plurality of sand-isolating fences 112, with sand-storage spaces 113 formed between adjacent sand-isolating fences 112 and corresponding first sand-storage nets 111 to prevent sand from moving along the first sand-storage nets 111 and facilitate subsequent sand clearing. This results in the sand-storage and sand-blocking structure 100 having good sand-blocking efficiency, increasing the amount of sand blocked and the range of sand-blocking control. Furthermore, as sand accumulates, a relatively tall and stable sand-blocking structure can be effectively formed, which itself also has a good sand-prevention and sand-guiding effect. This avoids extending the project period, thereby reducing the cost of wind and sand control projects and achieving good economic benefits.

[0088] Furthermore, the sand storage and blocking structure 100 avoids the need to construct multiple sand barrier fences, which would otherwise increase the area occupied by the wind and sand control project. This reduces the engineering difficulty and prevents the project from increasing the scope of disturbance to the local environment. Furthermore, the sand storage and blocking structure 100 is also suitable for use in windy and sandy areas such as those with large sand transport volumes, Gobi deserts with strong winds, and sand transport belts.

[0089] In an embodiment provided by the present invention, each sand-isolating fence 112 may be fixed to a side of the first sand storage net 111 or may be rotatable to better adapt to changes in wind direction, which is not limited in this embodiment.

[0090] In one embodiment provided by the present invention, multiple sand-isolating fences 112 are perpendicular to the first sand-storage net 111. When the first sand-storage net 111 is perpendicular to the direction of wind and sand flow, the sand-isolating fences 112 are perpendicular to the direction of wind and sand flow. This structure cooperates with the direction of wind and sand flow and has a better sand storage effect.

[0091] Figure 3 This is a schematic diagram of a top view of a sand storage and blocking structure according to another embodiment of the present invention. Figure 3 In one embodiment of the present invention, the end sand-screening fences 1121 at both ends of the sand-screening fence 112 are tilted outward. That is, the end sand-screening fences 1121 may not be parallel to the middle sand-screening fence 1122 located between the end sand-screening fences 1121, thereby forming an outwardly arched structure. This arched structure can expand the sand storage space 113 of the sand storage body 110. For example, the angle between the end sand-screening fences 1121 and the middle sand-screening fence 1122 may be 30° to 45°.

[0092] Figure 4 This is a front structural diagram of the first sand storage net provided by the present invention. Figure 5 This is a side structural diagram of the first sand storage net provided by the present invention, see Figures 4 and 5 In one embodiment of the present invention, the sand storage body 110 further includes a first column 114 . The first sand storage net 111 is fixed to the ground via the first column 114 .

[0093] In one embodiment, the mesh surface of the first sand storage net 111 is made of a non-air-permeable structural material, that is, the porosity is 0, for example, a high-density polyethylene plastic board, an aluminum-zinc-coated metal board, etc.

[0094] Specifically, the first sand storage net 111 includes: a fixed sand storage net 1111 and a flexible sand storage net 1112. The flexible sand storage net 1112 is arranged on the top of the fixed sand storage net 1111. The flexible sand storage net 1112 can rotate with the bottom end as the rotation center to adapt to different wind directions and block more sand.

[0095] Among them, the fixed sand storage net 1111 is rotatably set on the first column 114 through the top. After the sand in the sand storage room 113 is saturated, the fixed sand storage net 1111 can be opened to the sand corridor 130 and cleaned in time, so that the fixed sand storage net 1111 can be used sustainably.

[0096] The fixed sand storage net 1111 consists of a first frame 11111 and a first mesh surface 11112. The first mesh surface 11112 is a mesh structure made of metal wire and is fixed to the first frame 11111 and the first fixing wire 11113. The first frame 11111 is an aluminum-zinc-coated metal frame, and fixing posts 11114 are provided on the vertical frames at both ends of the first frame 11111.

[0097] Furthermore, a buckle 1141 for securing the sand storage net 1111 is provided on the first column 114. The fixed sand storage net 1111 is detachably connected to the buckle 1141 via the fixed column 11114. When cleaning the accumulated sand, the fixed column 11114 for securing the sand storage net 1111 is opened from the buckle 1141, with the top buckle 1141 not opened and the rest all opened, so that the fixed sand storage net 1111 rotates outward around the top buckle 1141. The support member can then be used to prop it up, so that the accumulated sand in the sand storage room 113 can be dumped out, making it easier to clean the sand in the sand corridor 130.

[0098] Furthermore, the flexible sand storage net 1112 is rotatably mounted on the first column 114 at its bottom end. During use, the orientation of the flexible sand storage net 1112 can be manually adjusted according to the wind direction, or it can be automatically controlled, which is not limited in this embodiment. Specifically, the flexible sand storage net 1112 is composed of a fixed frame 11121 and a flexible mesh body 11122. Furthermore, the fixed frame 11121 is an aluminum-zinc-plated metal frame. A second fixed wire 11123 is disposed between the fixed frame 11121. The flexible mesh body 11122 is fixed to the fixed frame 11121 and the second fixed wire 11123. Furthermore, the flexible mesh body 11122 is disposed on the windward side of the second fixed wire 11123.

[0099] In one embodiment provided by the present invention, the sand storage body 110 further includes: an intelligent adjustment hub 1113 , wherein the intelligent adjustment hub 1113 is used to drive the flexible sand storage net 1112 to rotate.

[0100] Specifically, the intelligent adjustment hub 1113 can drive the fixed frame 11121 of the flexible sand storage net 1112 to rotate. Furthermore, multiple states of the rotation of the flexible sand storage net 1112 can be preset. For example, the rotation of the flexible sand storage net 1112 has three fixed positions, including: (1) O position: the flexible sand storage net 1112 is in a vertical position; (2) X position: the flexible sand storage net 1112 is tilted 30° toward the leeward side; (3) Y position: the flexible sand storage net 1112 is tilted 30° toward the windward side.

[0101] The flexible sand storage net 1112 provided by the present invention can be adjusted in time according to changes in wind direction, and can be tilted toward the upwind direction 001. This can avoid the reduction of sand blocking and storage functions caused by different wind directions, and can achieve the effects of precise sand control and efficient sand storage.

[0102] The inclined mesh structure provided by the present invention can effectively form a vortex wind on the windward side, causing the airflow to form turbulence, thereby forming a wind shadow area on the windward side and accumulating a large amount of accumulated sand on the windward side.

[0103] Of course, the bottom end of the intelligent adjustment hub 1113 includes a power component, a control unit and a power supply unit, which will not be described in detail in this embodiment.

[0104] In an embodiment provided by the present invention, the sand storage body 110 further includes: a second column 115; the side ends of the sand isolation fence 112 are fixed by the second column 115, thereby preventing the sand isolation fence 112 from tipping over or dislocating.

[0105] In a further embodiment provided by the present invention, a first fixing ring 1142 is provided on the outer wall of the first column 114 . Specifically, the first fixing ring 1142 can be provided on the windward side.

[0106] In a further embodiment provided by the present invention, a second fixing ring 1151 is provided on the outer wall of the second column 115 . Specifically, the second fixing ring 1151 can be provided on the windward side.

[0107] The first fixing clip 1142 corresponds to the second fixing clip 1151 on the second column 115 set on the windward side, the third fixing wire 1124 is fixed on the first fixing clip 1142 and the corresponding second fixing clip 1151, and then the second mesh surface 1123 is laid and fixed on the third fixing wire 1124, thereby forming a sand-proof fence 112.

[0108] In one embodiment provided by the present invention, the first column 114 and the second column 115 are both extendable or shortened structures, so that the heights of the first column 114 and the second column 115 can be flexibly configured according to different needs, thereby achieving both the desired effect and cost savings.

[0109] In the above embodiment, the first column 114 includes: a first screw pile column 1143, a first surface column 1144, and at least one first detachable column 1145. The first screw pile column 1143 is arranged at the bottom of the first surface column 1144, and the first screw pile column 1143 is used to be buried in the ground to achieve fixation. At least one first detachable column 1145 is detachably arranged on the first fixed end 1146 at the top of the first surface column 1144. When the first surface column 1144 needs to be extended, the first detachable column 1145 can be quickly and conveniently installed. This structure is particularly suitable for areas with large sand transport volumes.

The material and structure of the blocking net 1211 are similar to those of the sand isolation fence 112, and the height can be 1.5m.

[0111] Figure 7 This is a schematic diagram of the structure of the second column provided by the present invention after being heightened; Figure 8 This is a schematic diagram of the structure of the detachable column provided by the present invention, see Figures 7 and 8. The second column 115 includes: a second spiral pile column 1152, a second surface column 1153 and at least one second detachable column 1154. Among them, the second spiral pile column 1152 is arranged at the bottom of the second surface column 1153, and the second spiral pile column 1152 is used to be buried in the ground to achieve fixation. At least one second detachable column 1154 is detachably arranged on the top of the second surface column 1153 through the second fixed end 1155. When the second surface column 1153 needs to be extended, the second detachable column 1154 can be installed quickly and conveniently. This structure is particularly suitable for areas with large sand transport. In addition, the sand-blocking net 121 can also be fixed by a third column 122, and the third column 122 can be the same as the second column 115. The third column 122 includes: a third spiral pile column 1221, a third surface column 1222 and at least one third detachable column. Among them, the third screw pile column 1221 is set at the bottom of the third surface column 1222, and the third screw pile column 1221 is used to be buried in the ground to achieve fixation. At least one third detachable column is detachably set on the third fixed end 1223 of the third surface column 1222. When the third surface column 1222 needs to be extended, the third detachable column can be quickly and conveniently installed. This structure is particularly suitable for areas with large sand transport. In a further embodiment provided by the present invention, a third fixing clamp 1224 is provided on the outer wall of the third column 122. Specifically, the third fixing clamp 1224 can be provided on the windward side.

[0112] Accordingly, the first sand storage net 111, the sand isolation fence 112 and the sand blocking body 120 can all be increased in height.

[0113] Specifically, the first detachable column 1145, the second detachable column 1154 and the third detachable column have the same structure, and their height can be 1m, and both ends are provided with fixed ends. A mesh surface and a fixed wire are provided between them.

[0114] In one embodiment provided by the present invention, the cross-sections of the first surface column 1144 , the second surface column 1153 , and the third surface column 1222 are square or circular.

[0115] Specifically, the cross-section of the first column 114 can be square, so that the first sand storage net 111 and the sand isolation fence 112 can be fixed on two adjacent surfaces. Furthermore, for the first sand storage net 111, a first detachable column 1145 can be installed at the upper end of the first surface column 1144 of the first column 114. The first detachable column 1145 has a similar structure to the first surface column 1144, is 1 meter high, and has square fixed ends at both ends. First, a mesh surface and fixed wire are installed between the first detachable columns 1145. Then, an intelligent adjustment hub 1113 and a flexible sand storage net 1112 are installed above the top fixed end of the first detachable columns 1145. The intelligent adjustment hub 1113 is used to drive the flexible sand storage net 1112 to rotate based on the received signal.

[0116] The first surface column 1144 of the first column 114 can be 2.0m in height and square in cross section, with a buckle 1141 provided on its leeward side. The buckle 1141 is hingedly fixed to the fixing column 11114. A first fixing clip 1142 is provided on the windward side of the first surface column 1144 of the first column 114. Both the upper and lower ends of the first surface column 1144 are square fixed ends, and the lower fixed end is fixed to the fixed end at the top of the buried first spiral pile column 1143. The buried first spiral pile column 1143 of the first column 114 can be 1.5m in height and 15cm in diameter. It is a solid structure with a spiral protrusion on its outer wall and a square fixed end at its top, with screw holes in four directions provided on the fixed end.

[0117] Specifically, the cross-section of the second column 115 can be square or circular, which is not limited in this embodiment. The second column 115 is composed of a buried second spiral pile column 1152 and a second surface column 1153. The second surface column 1153 is a hollow structure, and four vertical second fixing rings 1151 are set on its outer wall. The spacing between the second fixing rings 1151 is 20 cm. The upper and lower ends of the second column 115 are both circular fixed ends, and the lower fixed end is fixed to the fixed end at the top of the buried second spiral pile column 1152. The fixing wire is fixed between the second column 115 and the second column 115, and remains parallel to each other.

[0118] Among them, the above-mentioned spiral pile columns can be constructed using advanced spiral piles and spiral pile drivers, which improves construction efficiency and is more accurate. At the same time, the spiral pile columns have stronger stability and supporting force, which can ensure the stability of the sand storage and sand blocking structure 100.

[0119] It should be noted that the above-mentioned sand-proof fence 112 is composed of a second mesh surface 1123, a first column 114, a second column 115 and a third fixed iron wire 1124, wherein the second mesh surface 1123 can be made of flexible sand-proof net material, such as HDPE (High Density Polyethylene), PE (polyethylene), plant fiber and other materials, and the height can be 1.5m.

[0120] In one embodiment provided by the present invention, the structure of the sand barrier fence 112 is a triangle or trapezoidal structure so as to cope with different wind directions and wind and sand conditions.

[0121] In one embodiment provided by the present invention, a sand guide is provided at a position 8-10 m outside the extension line of the center line of each sand storage room 113 .

[0122] Specifically, the sand guide body is triangular in shape and has the function of guiding and gathering the sand flow. It can better gather the sand flow at the center line of the sand storage room 113 under the sand flow state, thereby guiding the sand flow to the greatest extent.

[0123] Figure 9 This is a schematic top plan view of a sand storage and blocking structure according to another embodiment of the present invention; Figure 10 This is a schematic diagram of a top view of a sand storage and blocking structure according to another embodiment of the present invention. Figures 9 and 10 In one embodiment provided by the present invention, the sand storage body 110 further includes: a second sand storage net 116, which is arranged parallel to one side of the first sand storage net 111, and the second sand storage net 116 intersects with the sand isolation fence 112, or the second sand storage net 116 is connected to the end of the sand isolation fence 112. The second sand storage net 116 can cooperate with the first sand storage net 111 to jointly enhance the sand storage capacity. Furthermore, the second sand storage net 116 can be lower than the first sand storage net 111 to receive the sand at the bottom and share the sand storage pressure for the first sand storage net 111.

[0124] Please continue to see Figure 10 In one embodiment of the present invention, the sand barrier 120 further includes a plurality of barrier fences 123 spaced apart on the side of the sand barrier 121 adjacent to the first sand storage net 111. Each barrier fence 123 forms a second predetermined angle with respect to the sand barrier 121. This second predetermined angle can be set based on wind direction, for example, between 45° and 135°, though this embodiment is not limited thereto. These barrier fences 123 further enhance the ability to block sand and dust.

[0125] The sand storage and blocking structure 100 provided by the present invention has the following advantages:

[0126] (1) Compared with traditional sand-blocking fences, the sand-storage and sand-blocking structure 100 of the present invention has the functions of high-efficiency sand blocking and large-capacity sand storage, and can meet special wind and sand disaster conditions such as large sand transport volume, Gobi strong wind area, and sand transport belt.

[0127] (2) The sand storage and blocking structure 100 provided by the present invention occupies a small area and has a greatly improved sand storage and blocking capacity per unit area. In addition, the sand storage body 110 is combined with the rear sand blocking body 120, which conforms to the law of wind and sand movement and can effectively block sand-blocking materials.

[0128] (3) The sand storage and blocking structure 100 provided by the present invention adopts a spiral pile column and an assembleable heightened column structure, which is convenient for mechanical operation and can be applied in engineering projects on a large scale, thereby improving construction efficiency.

[0129] (5) The vertical sand-blocking net 121 forms a sand accumulation area because it can form a wind shadow area with a lower wind speed on the leeward side of the net surface, while the windward side forms a sand accumulation area due to the blocking effect of the web. Since its vertical structure easily forms an acceleration area above the net surface, it is easy to cause sand particles on the windward side to roll over the net surface, resulting in more sand particles passing through and over the net surface, forming a phenomenon in which the sand accumulation is concentrated on the leeward side. The inclined net surface structure provided by the present invention can effectively form a vortex wind on the windward side, causing the air flow to form turbulent flow, thereby forming a wind shadow area on the windward side, and accumulating a large amount of accumulated sand on the windward side. On the other hand, the semi-enclosed space formed by the three-sided blocking net in the sand storage room 113 can form a large area of wind shadow area in the sand storage room 113. Once the wind and sand flow enters the sand storage room 113, it enters a sedimentation state, thereby realizing the function of sand accumulation.

[0130] (6) In reality, the wind and sand in the wild are more complicated. In addition to the airflow from the main wind direction, there will also be a leeward airflow that runs counter to the main wind direction. The leeward airflow easily causes the accumulated sand formed in the sand control project to become a sand source again and move to the side of the main wind direction, thereby reducing the sand blocking efficiency of the sand control project. The flexible sand storage net 1112 provided by the present invention can make timely adjustments according to the changes in wind direction and tilt toward the upwind direction 001. This can avoid the reduction of sand blocking and storage functions caused by different wind directions, and can achieve the functions of precise sand control and efficient sand storage.

[0131] Example 2

[0132] The present invention provides a wind and sand monitoring system. Figure 11 This is the layout diagram of the wind and sand monitoring system provided by the present invention, please refer to Figure 11The wind and sand monitoring system includes a wind speed and direction sensor 200, a sand accumulation monitoring sensor 300, a control unit, and any of the aforementioned sand storage and blocking structures 100. The wind speed and direction sensor 200 is located upwind of the sand storage and blocking structure 100; the sand accumulation monitoring sensor 300 is located in the sand storage compartment 113 of the sand storage and blocking structure 100; and the control unit is electrically connected to the intelligent adjustment hub 1113 in the sand storage body 110 to control the start and stop of the intelligent adjustment hub 1113, which is used to drive the rotation of the flexible sand storage net 1112.

[0133] Among them, the bottom end of the fixed frame of the flexible sand storage net 1112 is fixed at the intelligent adjustment hub 1113, and the bottom end of the intelligent adjustment hub 1113 is fixed at the top of the first surface column 1144, which contains power parts, control units and power supply units.

[0134] Specifically, the intelligent adjustment hub 1113 can drive the fixed frame of the flexible sand storage net 1112 to rotate. Furthermore, multiple states of the rotation of the flexible sand storage net 1112 can be preset. For example, the rotation of the flexible sand storage net 1112 has three fixed positions, including: (1) O position: the flexible sand storage net 1112 is in a vertical position; (2) X position: the flexible sand storage net 1112 is tilted 30° toward the leeward side; (3) Y position: the flexible sand storage net 1112 is tilted 30° toward the windward side.

[0135] Furthermore, the control unit is a remote control system with built-in remote signal transmission and control capabilities. The power supply unit utilizes an internal battery and / or an external power source, connected to the internal battery via a power transmission line. For example, a photovoltaic power supply system can be used. This system, comprised of a sensor-compatible monolithic photovoltaic power supply assembly, relies on sunlight to provide power to the sensor, ensuring proper operation.

[0136] The wind speed and direction sensor 200 can collect data such as wind speed Ws and wind direction Wd, and has functions such as data collection, storage, and transmission. For example, the wind speed and direction sensor 200 can be set at 20-30m on the windward side of the sand storage body 110, and the wind speed and direction sensor 200 can be 2m above the ground surface.

[0137] The sand accumulation monitoring sensor 300 can collect sand accumulation height h data and has functions such as data collection, storage, and transmission. For example, the sand accumulation monitoring sensor 300 can be set on the center line of the sand storage room 113 at a position 0.5-1.0m away from the fixed sand storage net 1111, and the height can be 2.5m.

[0138] Unless otherwise specified, the wind speed W0 mentioned in this application refers to the critical wind speed at which sand begins to move. This speed varies across regions, depending on factors such as local sand particle size, surface roughness, and moisture. Publicly available data indicates that the wind speed W0 at a height of 2 meters in northwest my country's sandy regions is approximately 5.0-6.0 m / s.

[0139] Unless otherwise specified, the wind speed Ws mentioned in this application refers to the hourly average wind speed.

[0140] Example 3

[0141] The present invention provides a sandstorm monitoring method. Figure 12 This is a flow chart of the wind and sand monitoring method provided by the present invention, please refer to Figure 12 The wind and sand monitoring method can be applied to the above-mentioned wind and sand monitoring system, and the wind and sand monitoring method includes:

[0142] 101. The wind speed and direction sensor 200 monitors wind speed and direction.

[0143] 102. The sand accumulation monitoring sensor 300 monitors the height of the sand accumulation.

[0144] 103. Based on the wind speed, wind direction and sand accumulation height, the flexible sand storage net 1112 is controlled to rotate to a corresponding angle.

[0145] This kind of prevention can more efficiently promote the sand storage and blocking structure 100 to play a better role.

[0146] Specifically, the wind and sand monitoring method includes:

[0147] (1) Positioning Marking: Based on the direction of the wind and sand flow and the planning and design, coordinate points are marked on the ground using calibration instruments such as GPS (Global Positioning System) and total stations, and markers are placed at the first column 114, the second column 115 and other positioning points;

[0148] (2) Installing columns: According to the coordinate point position, use a screw pile driver to drive the buried screw pile columns into the ground in sequence, and then set up the surface columns on them. Be sure to determine the direction of the clamping rings and screw holes on each surface column.

[0149] (3) Installing the first sand storage net 111: Fix the first sand storage net 111 between the first surface columns 1144, then install the intelligent adjustment hub 1113 on the top of the first surface columns 1144, and then install the first frame 11111, the first fixing wire 11113, and the flexible sand storage net 1112 in sequence.

[0150] (4) Installing the sand barrier fence 112 and the sand blocking net 121: According to the design, the blocking net and the separation net are first set up, and the fixed iron wires are connected between the adjacent columns on the sand blocking net 121 so that the entire fixed iron wire forms a fixed wire mesh surface; then the sand blocking net 121 body is fixed on the wire mesh surface, thus completing the net surface structure of the sand storage and blocking structure 100.

[0151] (5) Install other components in the wind and sand monitoring system: Install wind speed and direction sensor 200, sand accumulation monitoring sensor 300 and control unit. The monitoring data includes wind speed Ws, wind direction Wd, sand accumulation height h, etc., and transmits the data to the control unit, so that the intelligent adjustment hub 1113 can drive the flexible sand storage net 1112 to rotate. The rotation movement has three fixed position states, including: O position, X position, and Y position. The specific control system commands are as follows:

[0152] (5.1) When Ws < W0 (sand-raising wind speed) or the sand accumulation height h ≧ 2 m, the flexible sand storage net 1112 is set to position O, that is, the flexible sand storage net 1112 is set to a vertical position.

[0153] (5.2) When the wind direction Wd comes from the windward side and the stacking angle with the direction of the barrier net is 80°-100°, the wind speed Ws ≥ W0 (sand-lifting wind speed), and the sand accumulation height h is less than 2m, the flexible sand storage net 1112 is set to the Y position, that is, the flexible sand storage net 1112 is inclined to the windward side and the angle with the vertical direction is 30°.

[0154] (5.3) When the wind direction Wd comes from the leeward side and the angle with the direction AA of the barrier net is 80°-100°, the wind speed Ws ≥ W0 (sand-lifting wind speed), and the sand accumulation height h is less than 2m, the flexible sand storage net 1112 is set to the Y position, that is, the flexible sand storage net 1112 is inclined to the leeward side and the angle with the vertical direction is 30°.

[0155] (6) Cleaning up accumulated sand: When the accumulated sand monitoring sensor 300 shows that the accumulated sand height h≧2m, the accumulated sand in the sand storage and blocking structure 100 is cleaned up immediately.

[0156] Specifically:

[0157] When clearing the accumulated sand, the fixed columns 11114 of the sand storage net 1111 are opened from the buckles 1141, wherein the top buckle 1141 is not opened and the rest are all opened, so that the fixed sand storage net 1111 rotates outward around the top buckle 1141. The fixed sand storage net 1111 can be propped up using a support member to allow the accumulated sand in the sand storage room 113 to be poured out. The sand is then excavated using a forklift and loaded into a box truck, which is then used to transport the sand out. The accumulated sand in the sand storage room 113 and near the sand blocking body 120 is then cleared.

[0158] Furthermore, the wind and sand monitoring method further includes:

[0159] (7) Raise the height of the first sand storage net 111, the sand isolation fence 112 and the sand blocking body 120, and extend the sand isolation fence 112: When the sand accumulation monitoring sensor 300 shows that the sand accumulation height h≧2m, add one more section of the first detachable column 1145 upwards from the first surface column 1144 on the surface of the first sand storage net 111 and the sand isolation fence 112. At that time, the height of the first sand storage net 111 will reach 4.0m, and the height of the sand isolation fence 112 will reach 2.5m; at the same time, the sand isolation fence 112 will be extended by 3.0m in the direction of its extension line to set up new columns, and the blocking net body on the sand isolation fence 112 will be extended.

[0160] In this embodiment, by raising the first sand storage net 111, the sand isolation fence 112, the sand blocking body 120, and lengthening the sand isolation fence 112, the sand storage and blocking capacity of the sand storage and blocking structure 100 is expanded, thereby realizing the function of large-capacity sand storage.

[0161] In one embodiment provided by the present invention, when proceeding to stage (6), another method can also be adopted, as follows:

[0162] (8) Close the sand storage room 113: When the sand accumulation monitoring sensor 300 shows that the sand accumulation height h≧2m, the open side of the sand storage room 113 is connected with a mesh to form a closed compartment, thus forming a closed sand storage room 113, which can further play the role of sand storage and sand blocking.

[0163] The wind and sand monitoring method provided in this embodiment has at least the following advantages:

[0164] (1) Compared with traditional sand-blocking fences, the wind and sand monitoring method provided by the present invention adopts advanced screw piles and screw pile drivers for construction, which improves construction efficiency and is more accurate. At the same time, the screw pile columns have stronger stability and supporting force, which can ensure the stability of the sand storage and sand blocking structure 100.

[0165] (2) The wind and sand monitoring method provided in this embodiment determines the sand accumulation situation of the sand storage and sand blocking structure 100 by monitoring the accumulated sand, and promptly cleans the accumulated sand in the sand accumulation corridor 130 and transports the accumulated sand out, thereby ensuring that the sand accumulation corridor 130 is in a clean sand state, thereby ensuring that the rear sand blocking body 120 is always kept in an unsaturated state, thereby preventing sand from crossing over the rear sand blocking body 120 and entering the protection area, thereby achieving a dual protection effect and ensuring the sustainability of the sand storage and sand blocking function of the sand storage and sand blocking structure 100.

[0166] (3) The sand storage and blocking structure 100 proposed in this embodiment has the functions of being heightened, extended, and expandable. On the one hand, it ensures the increase of its sand storage capacity and the sustainability of its sand blocking and storage function. On the other hand, it enables the functionality of the sand storage and blocking structure 100 to better adapt to flexible use in different scenarios, with strong adaptability and operability.

In addition, it also includes: sand fixation grids 500 and roadbed 400. The following description takes the sand storage and sand blocking structure 100 as an example.

[0169] In this embodiment, unless otherwise specified, the direction of the wind and sand flow moves from upwind direction 001 to downwind direction; the direction of the first sand storage net 111 of the sand storage body 110 is perpendicular to the direction of the wind and sand flow; the direction of the sand fixation grid 500 is perpendicular to the direction of the wind and sand flow; and the direction of the roadbed 400 is almost perpendicular to the direction of the wind and sand flow.

[0170] The distance between the sand blocking body 120 in the sand storage and blocking structure 100 and the slope foot of the roadbed 400 can be 80-100 m.

[0171] The aforementioned sand-fixing grid 500 comprises two arrays of sand-fixing grids 500, made of high-density polyethylene (HDPE). The grids 500 can be 20 cm tall, with a grid size of 1.5 m x 1.5 m. Each array can be 30 m wide, and the width of the empty corridor between the two arrays can be 6-8 m. The distance between the upwind edge of the sand-fixing grid 500 array and the sand barrier 120 can be 10 m. The distance between the downwind edge of the sand-fixing grid 500 array and the toe of the roadbed 400 slope can be 4-5 m.

[0172] The roadbed 400 can be any railway or highway roadbed 400. The roadbed 400 is an embankment structure, with the road surface higher than the ground and with side slopes on both sides.

[0173] The wind and sand control system provided in this embodiment has at least the following advantages:

[0174] 1. The wind and sand control system provided in this embodiment is suitable for wind and sand control projects on transportation routes such as railways and highways in desert areas. Because transportation routes are limited by the space that can be requisitioned and set up along the routes when setting up wind and sand control projects, they cannot occupy too much space. This wind and sand control system adopts a sand storage and sand blocking structure 100 to minimize the distance occupied, meet the needs of wind and sand control projects on transportation routes, and also reduce disturbance to the environment.

[0175] 2. Compared with traditional sand-blocking fences, the wind-sand control system provided in this embodiment can more effectively block sand and store sand easily, accumulating sand in the sand-storing and blocking structure 100, thereby reducing sand damage to the roadbed 400.
