Description

Technical Field

[0001] This invention relates to the field of wind and sand control technology, and in particular to a wind-breaking sand-blocking wall system. Background Technology

[0002] With the rapid economic development of western my country, infrastructure construction such as railways, highways, and urban development has been widely carried out in the desert and Gobi regions of Northwest my country. However, wind and sand hazards in these desert and Gobi regions have always been a factor hindering road construction and safe operation in these areas. Necessary protective measures are needed to reduce the harmful effects of wind and sand.

[0003] Commonly used protective measures in engineering include sand stabilization and sand retaining. Sand stabilization involves planting vegetation to absorb and fix the sand; sand retaining involves constructing retaining walls, such as earthen grids or stone grids, to block wind and sand. Because vegetation planting is greatly affected by natural conditions, sand retaining walls are more commonly used in engineering.

[0033] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0034] Example 1

[0035] Please refer to Figure 1-9 As shown, the present invention provides a wind-breaking sand-blocking wall system, including a sand-blocking wall 1, a first wind-breaking component 2 at the front end of the sand-blocking wall 1, the first wind-breaking component 2 including a connecting plate 21, and first wing plates 22 on both sides of the top of the connecting plate 21. The first wing plates 22 are streamlined and the two sets of first wing plates 22 are spliced ​​to form an arc-shaped structure protruding away from the sand-blocking wall 1. The connecting plate 21 is a hollow plate, and a fixed section 221 is fixedly connected to the top of the connecting plate 21. A movable section 222 is provided above the fixed section 221 and is hinged to the fixed section 221. A sand-blocking mechanism is provided at the end of the sand-blocking wall 1 near the sand-blocking wall 1 and at the end of the first wind-breaking component 2 near the sand-blocking wall 1. One end of component 2 is provided with a second wind-breaking component 5. The second wind-breaking component 5 includes two opposing second wing plates 51. The second wing plates 51 are streamlined and are spliced ​​together to form an arc-shaped structure protruding away from the sand-retaining wall 1. A mounting plate 511 is fixedly connected to the bottom of the second wing plate 51 and is buried in the sand. The first wind-breaking component 2 and the second wind-breaking component 5 are staggered. A drive component 3 is provided below the first wind-breaking component 2, and a support component is provided on the inner side of the first wind-breaking component 2. When wind and sand blow towards the sand-retaining wall 1, the wind-breaking mechanism first contacts the wind and sand, guides and disperses the strong wind, and converts the wind direction into vertical and horizontal components, forming a converging flow to achieve the purpose of wind breaking. The number of the first wind-breaking component 2 and the second wind-breaking component 5 is set according to the local wind conditions. The second wind-breaking component 5 and the first wind-breaking component 2 are staggered. After being broken by the first wind-breaking component 2, the strong wind continues to move to the second wind-breaking component 5 for secondary wind breaking. The second wind-breaking component 5 does not rotate with the wind direction and remains parallel to the sand-blocking wall 1. Regardless of the angle at which the first wind-breaking component 2 rotates with the wind direction, the wind direction after passing through the second wind-breaking component 5 will be guided to be parallel to the sand-blocking wall 1 and vertical, further reducing the impact of the strong wind on the sand-blocking wall 1.

[0036] As a further implementation of this embodiment, such as Figure 1 and Figure 2As shown, the drive assembly 3 includes a wind direction monitor 31 and a motor 32 connected in the same central control system. The wind direction monitor 31 is located on the side of the first wing plate 22. A fixed box 321 is provided outside the motor 32. The fixed box 321 is buried in the sand. The connecting plate 21 is fixedly connected to the top of the fixed box 321 and the connecting plate 21 is flush with the ground. The output shaft of the motor 32 extends upward to connect with the connecting plate 21. An arc-shaped slot 3211 is provided in the fixed box 321. A support block 211 is fixedly connected to the bottom of the connecting plate 21. The support block 211 is embedded in the slot 3211. The length of the slot 3211 is set so that the maximum rotation angle of the connecting plate 21 in both clockwise and counterclockwise directions is 30°.

[0037] During sandstorms, the wind direction monitor 31 monitors the wind direction and transmits the information to the central control system. Upon receiving the signal, the central control system controls the motor 32 to rotate. The motor 32 drives the connecting plate 21 to rotate, which in turn drives the first wing plate 22 to rotate, causing the first wing plate 22 to rotate with the wind direction, allowing the wind to blow directly onto it. The first wing plate 22 guides and disperses the strong wind, converting the wind direction into vertical and horizontal components, forming a converging current and achieving the purpose of breaking the wind, thus reducing the impact of strong winds on the sand-blocking wall 1. Furthermore, the length of the slot 3211 determines the rotation angle of the connecting plate 21. The length of the slot 3211 can be set according to local meteorological conditions. In this embodiment, the length of the slot 3211 is set such that the maximum clockwise and counterclockwise rotation angle of the connecting plate 21 is 30°. The greater the rotation angle of the first wing plate 22, the closer the wind direction guided by the first wing plate 22 will be to being perpendicular to the sand-blocking wall 1. The rotation angles of the connecting plate 21 and the first wing plate 22 are limited to within 30° to prevent the first wing plate 22 from rotating too much and losing its wind-breaking effect relative to the sand-blocking wall 1.

[0038] As a further implementation of this embodiment, such as Figure 3 and Figure 4As shown, the support assembly includes a fixed rod 41 and a movable rod 42. The fixed rod 41 is fixedly connected between the fixed section 221 and the connecting plate 21. Several fixed rods 41 are provided. The movable rod 42 includes an outer tube 421, an inner rod 422 and a first elastic element 423. The outer tube 421 is rotatably connected to the connecting plate 21. The inner rod 422 is inserted into the outer tube 421 and is slidably connected to the outer tube 421. The inner rod 422 is rotatably connected to the movable section 222. The first elastic element 423 is fixedly connected between the inner rod 422 and the outer tube 421, and the first elastic element 423 drives the inner rod 422 to move towards the movable section 222. The length ratio of the movable section 222 to the fixed section 221 is 1:4.

[0039] The support assembly supports the fixed section 221 and can drive the flipped movable section 222 to return to its original position. Without external force, the movable section 222 remains connected to the fixed section 221. Under wind and sand conditions, the movable section 222 flips, causing the inner rod 422 and outer tube 421 to move relative to each other. The first elastic element 423 is compressed, converting wind force into the elastic potential energy of the first elastic element 423, further enhancing the resistance of the first wing plate 22 to strong winds.

[0040] As a further implementation of this embodiment, such as Figure 5-9As shown, the sand-blocking mechanism and the second wind-breaking component 5 are arranged alternately. The sand-blocking mechanism includes a base 6, a sand-blocking plate 7, and a vibrating component 8. After the sand passes through the wind-breaking system, the wind speed is reduced, and the sand and dust are blocked and deposited in the sand-blocking mechanism, thereby effectively preventing the spread and invasion of sand and dust. The base 6 is buried in the sand. A receiving groove 61 is opened on the top of the base 6. A partition 65 is set in the receiving groove 61. The partition 65 separates the connecting plate 81 from the sand and dust dumped by the cover plate 62, reducing the impact of sand and dust on the rotation of the connecting plate 81. A cover plate 62 is set in the receiving groove 61. The cover plate 62 is hinged to the side wall of the base 6. A second elastic element 63 is set between the cover plate 62 and the base 6. The elastic coefficient of the second elastic element 63 is greater than that of the third elastic element 712. When there is no external force, the second elastic element 63 keeps the plate in a horizontal state. As sand accumulates on the cover plate 62, the cover plate 62 rotates to dump the sand. The vibratory assembly 8 includes a connecting plate 81 and a vibratory rod 82. The connecting plate 81 is rotatably disposed in the receiving groove 61, and the vibratory rod 82 is rotatably connected to the connecting plate 81. The connecting plate 81 is an eccentric plate, so that the connecting plate 81 is in a horizontal state when no external force is applied. The base 6 is provided with several receiving platforms 64 corresponding to the vibratory rod 82, and the vibratory rod 82 overlaps on the corresponding receiving platform 64. The sand-blocking plate 7 includes a bottom plate 71 and side plates 72. The bottom plate 71 and the side plates 72 are vertically slidably connected. A fixing plate 721 is fixedly connected between two opposite side plates 72. The fixing plate 721 is located below the bottom plate 71. A rotating rod 711 is provided on the bottom plate 71. The axis of the rotating rod 711 is perpendicular to the sand-blocking wall 1, and the rotating rod 711 is vertically slidably connected to the side plates 72. The base plate 71 is rotatably connected to the rotating rod 711, with the rotation axis of the base plate 71 parallel to the axis of the rotating rod 711. A third elastic element 712 is provided between the fixed plate 721 and the rotating rod 711. A stop block 722 is provided on the inner side of the side plate 72, and the stop block 722 is located on the sliding path of the base plate 71. A groove 723 is provided on the side plate 72 opposite to the stop block 722. A reinforcing member 713 is provided on the top of the inner side of the side plate 72. The reinforcing member 713 includes a rigid rod 7131 and an elastic head 7132. One end of the rigid rod 7131 is fixedly connected to the side plate 72, and the elastic head 7132 is fixedly connected to the other end of the rigid rod 7131. The elastic element is a frustum structure with its tip away from the rigid rod 7131. A through hole is provided on the base plate 71, and the elastic element can be inserted into the through hole. The through hole is located on the base plate 71 near the groove 723.The elastic head 7132 is inserted into the through hole, providing a certain pulling force to the base plate 71, ensuring that the base plate 71 moves downwards before rotating. A push rod 621 is fixedly connected to the bottom of the cover plate 62. The vibrating rod 82 is rotatably connected to the connecting plate 81. The rotation axis of the vibrating rod 82 is parallel to the rotation axis of the connecting plate 81, and the rotation axis of the connecting plate 81 is parallel to the rotation axis of the cover plate 62. A striking block 822 is provided on the side of the vibrating rod 82 away from the connecting plate 81. The striking block 822 is connected to the vibrating rod 82 via a connecting line 821, which is a flexible wire. The rotation of the cover plate 62 drives the push rod 621 to push the connecting plate 81 to rotate. The height of the receiving platform 64 and its distance from the sand-blocking chamber are different. When the connecting plate 81 is in a horizontal state, the vibrating rod 82 overlaps on the corresponding receiving platform 64. The rotation of the connecting plate 81 drives the vibrating rod 82 to rotate. The vibrating rod 82, with the smallest angle between itself and the connecting plate 81, rotates first until it comes into contact with the sand-blocking plate 7, striking the sand-blocking plate 7. After the vibrating rod 82 contacts the sand-blocking plate 7, it can no longer rotate with the connecting plate 81. At this point, the connecting plate 81 continues to rotate, and the vibrating rod 82 rotates relative to the connecting plate 81. As the connecting plate 81 continues to rotate, the vibrating rod 82 strikes the sand-blocking plate 7 sequentially according to the angle between itself and the connecting plate 81. That is, one rotation of the connecting plate 81 achieves multiple strikes on the sand-blocking plate 7, shaking off the sand and dust deposited on the sand-blocking plate 7. When the connecting plate 81 is reset, it drives the vibrating rod 82 to rotate. After the vibrating rod 82 rotates to abut against the corresponding receiving platform 64, it stops rotating. As the vibrating rod 82 rotates, the striking block 822 is thrown onto the sand-blocking plate 7 to strike the sand-blocking plate 7, increasing the striking force on the sand-blocking plate 7 and further improving the cleaning effect of the sand accumulated on the sand-blocking plate 7.

[0041] As sand and dust accumulate on the base plate 71, it gradually moves downwards. The third elastic element 712 is compressed. Under the influence of gravity, the base plate 71 moves downwards to the stop block 722, which prevents it from moving further downwards. At this point, the base plate 71 moves to the groove 723, and the sand and dust on the base plate 71 slides down from the groove 723. As the sand and dust slides down into the groove 723, the center of gravity of the sand and dust also shifts towards the groove 723, causing the base plate 71 to rotate and accelerating the dumping of sand and dust. The sand and dust falling from the sand-blocking chamber accumulates on the cover plate 62. After accumulating to a certain amount, the cover plate 62 rotates. The push rod 621 rotates with the cover plate 62, pushing the connecting plate 81 to rotate. The rotation of the connecting plate 81 drives the vibrating rod 82 to rotate, striking the sand-blocking plate 7, causing the sand and dust accumulated on the sand-blocking plate 7 to fall off, preventing the sand-blocking plate 7 from being blocked and ensuring the ventilation function of the sand-blocking plate 7.

[0042] Specific working principle:

[0043] In strong winds and sandstorms, the sand is blown towards the sand-blocking wall 1 through the wind-breaking system and the sand-blocking system in sequence. The wind direction monitor 31 on the first wing plate 22 monitors the wind direction and transmits the signal to the central control system. After receiving the signal, the central control system controls the motor 32 to start. The motor 32 drives the first wing plate 22 to rotate through the connecting plate 21, so that the wind blows directly onto the first wing plate 22. The first wing plate 22 guides and disperses the strong wind, converting the wind direction into vertical and horizontal components, forming a converging flow, achieving the purpose of breaking the wind and reducing the impact of the strong wind on the sand-blocking wall 1. If the wind force is too strong, the movable section 222 of the first wing plate 22 deflects, and the first elastic element 423 is compressed. After the wind force decreases, the first elastic element 423 recovers its deformation, causing the movable section 222 to return to its original position.

[0044] The strong wind decreases after passing through the first wind-breaking component 2 and then blows towards the second wind-breaking component 5. The angle between the second wind-breaking component 5 and the sand-blocking wall 1 remains unchanged. Therefore, the wind passing through the second wind-breaking component 5 is always converted into a direction parallel to the sand-blocking wall 1 and vertical, reducing the impact of the strong wind on the sand-blocking wall 1.

[0045] The wind speed decreases after passing through the wind-breaking system, and the sand and dust are blocked by the sand-blocking plate 7 and deposited in the sand-blocking chamber, thus effectively preventing the spread and invasion of wind and sand. As sand and dust accumulate in the sand-blocking chamber, the bottom plate 71 moves downward and the third elastic element 712 is compressed. When the bottom plate 71 moves to the stop block 722, it can no longer move downward. At this time, the sand and dust on the bottom plate 71 slides down from the groove 723, and as the sand and dust slide down, the bottom plate 71 rotates, accelerating the dumping of sand and dust on the bottom plate 71.

[0046] The bottom plate 71 spills sand and dust onto the cover plate 62. As the sand and dust accumulate on the cover plate 62, the second elastic element 63 is compressed, causing the cover plate 62 to rotate. The push rod 621 rotates with the cover plate 62, pushing the connecting plate 81 to rotate. The rotation of the connecting plate 81 drives the vibrating rod 82 to rotate. The rotation of the vibrating rod 82 causes the vibrating block to strike the sand-blocking plate 7, causing the sand and dust accumulated on the sand-blocking plate 7 to fall off, preventing the sand-blocking plate 7 from being blocked and ensuring the ventilation function of the sand-blocking plate 7.

[0047] Example 2

[0048] Reference Figures 10-12Unlike Embodiment 1, in Embodiment 2, the thickness of the connecting plate 21 is greater than that in Embodiment 1. A hidden groove 212 is provided on the connecting plate 21, and a rotating plate 213 is provided in the hidden groove 212. A screw 214 that drives the rotating plate 213 to rotate and a bevel gear 216 that drives the screw 214 to move are provided in the hidden groove 212. A connecting cylinder 217 with a vertical axis is rotatably connected in the hidden groove 212. A flat gear 215 is sleeved on the connecting cylinder 217 and is fixedly connected to the connecting cylinder 217. The bevel gear 216 is rotatably connected to the connecting plate 21, and a rocker arm is fixedly connected to the bevel gear 216. The screw 214 is inserted into the connecting cylinder 217 and is threadedly connected to the connecting cylinder 217. The other end of the screw 214 is hinged to the rotating plate 213, and the hinge point between the screw 214 and the rotating plate 213 is located away from the rotation axis of the rotating plate 213. The angle of the rotating plate 213 is adjusted according to local weather conditions, thereby adjusting the angle of the first wing plate 22. When adjusting the angle, the bevel gear 216 is rotated by a rocker arm. The bevel gear 216 drives the spur gear 215 to rotate, which in turn drives the connecting cylinder 217 to rotate. Due to the threaded connection between the screw 214 and the connecting cylinder 217, and the limiting effect of the screw 214 at the connection point with the connecting plate 21, the rotation of the connecting cylinder 217 drives the screw 214 to move vertically. The vertically moving screw 214 pushes the rotating plate 213 to rotate, thus adjusting the angle of the rotating plate 213.
