Description

Technical Field

[0001] This invention relates to the field of engineering sand control technology, and more specifically, to a sand-blocking and sand-guiding device suitable for multi-wind-direction Gobi areas. Background Technology

[0002] In recent years, with the completion and opening of numerous railways traversing the Gobi and desert regions, the problem of sand damage to railway roadbeds has gradually emerged. Many railway lines choose to use sand-blocking boards for wind and sand protection when passing through Gobi or desert areas. This can easily cause sand to accumulate around the sand-blocking boards on the side closer to the sand source. At the same time, a large amount of manual labor is needed to clear the sand to prevent it from being blown onto the rails.

[0003] The inventors' research revealed that existing sand-blocking plate designs primarily consider the relationship between sand-blocking efficiency and porosity under single-season wind direction and speed conditions. They only consider the sand-blocking effect of the sand-blocking plate, with relatively little consideration given to maximizing sand-blocking efficiency by adjusting porosity, pore angle, sand-blocking plate height, and windward deployment angle of the sand-blocking plate according to seasonal, wind direction, and wind speed changes. Furthermore, existing sand-blocking plate designs are relatively dense, meaning they have strong wind-blocking capacity but poor stability, making the sand-blocking plates easily blown over and posing safety hazards. Summary of the Invention

[0004] The purpose of this invention is to provide a sand-blocking and sand-guiding device suitable for multi-wind-direction Gobi areas. It can mainly block sand in the main wind direction, while also taking into account the sand transport and sand clearing functions in the secondary wind direction. It has multiple functions and high safety.

[0005] The embodiments of the present invention are implemented as follows:

[0006] This invention provides a sand-blocking and sand-guiding device suitable for multi-wind-direction Gobi desert areas, comprising:

[0007] The frame has opposing windward and leeward sides;

[0008] Multiple spoiler fans mounted on the rack;

[0009] Multiple porous tubes are rotatably mounted on the frame, located below the spoiler fan, and each porous tube has a sand guide hole to guide sand from the windward side to the leeward side.

[0010] A first solar panel is slidably mounted on the frame, the first solar panel being located on the side of the plurality of spoiler fans away from the leeward side;

[0011] A first drive mechanism is installed on the frame and connected to the pore tube. The first drive mechanism is used to drive the pore tube to rotate in order to adjust the windward angle of the sand guide hole.

[0012] And a second drive mechanism mounted on the frame, the second drive mechanism being connected to the first solar panel and used to drive the first solar panel to slide relative to the frame.

[0013] In an optional embodiment, the spoiler fan protrudes from the pore tube in the direction from the leeward side to the windward side.

[0014] In an optional embodiment, a sand-guiding slope is provided at the top of the pore tube.

[0015] In an optional embodiment, multiple pore tubes at the same height are connected sequentially, and the first drive mechanism is connected to the pore tube located on the side of the multiple pore tubes at the same height.

[0016] In an optional embodiment, a force transmission rod is installed on the pore tube, and the force transmission rod is rotatably connected to the frame via a bearing; the first drive mechanism includes a first motor, a tension wheel assembly, a transmission bar, and a transmission wheel. The first motor and the tension wheel assembly are both installed on the frame. The first motor is drively connected to the tension wheel assembly. The transmission bar is sleeved on the outside of the tension wheel assembly. The transmission wheel meshes with the transmission bar. The transmission wheel is sleeved on the outside of the force transmission rod and is fixedly connected to the force transmission rod.

[0017] In an optional embodiment, the frame is provided with an installation channel, and the drive bar is located within the installation channel.

[0018] In an optional embodiment, the frame includes two opposing columns and a crossbar connected to the two columns, the first solar panel is installed between the two columns, and the deflector fan is connected to the crossbar.

[0019] In an optional embodiment, a transmission rack is mounted on the first solar panel, and the second drive mechanism includes a second motor and a transmission gear. The second motor is connected to the frame, and the transmission gear is mounted on the output shaft of the second motor and meshes with the transmission rack.

[0020] In an optional embodiment, the sand-blocking and sand-guiding device suitable for multi-wind-direction Gobi areas further includes an infrared sensor and a sand-clearing mechanism. The infrared sensor is communicatively connected to the sand-clearing mechanism and is installed on the frame to detect the thickness of the sand layer at the bottom of the frame. The sand-clearing mechanism is installed at the bottom of the frame to clean up accumulated sand.

[0021] In an optional embodiment, the sand-clearing mechanism includes a controller, an expansion joint, and a sand-clearing plate. The controller is communicatively connected to the expansion joint, the expansion joint is mounted on the frame, and the sand-clearing plate is connected to the expansion joint. The infrared sensor is communicatively connected to the controller.

[0022] The beneficial effects of the embodiments of the present invention are:

[0023] In summary, the sand-blocking and guiding device for multi-wind-direction Gobi desert areas provided in this embodiment, during operation, sees sand blown towards the windward side of the frame. The sand blows a spoiler fan, which rotates under the influence of the sand, thus agitating the sand, reducing its force and speed. This allows sand particles to fall onto the windward-facing ports of the guiding holes under the influence of the spoiler fan and their own gravity. This reduces the damage caused by wind to the sand-blocking and guiding device, making the entire device more stable and safer. Simultaneously, under the influence of wind, sand particles move from the windward side of the guiding holes to the leeward side, preventing sand accumulation at the bottom of the frame and avoiding blockage of the guiding holes. Furthermore, the angle of the perforated tube can be adjusted by the first drive mechanism, thereby adjusting the windward angle of the guiding holes and changing the movement pattern of the sand particles. This improves upon the problem of existing sand-blocking plates whose efficiency is limited by local seasonal wind speed and direction changes, allowing for adjustments to the sand-blocking strategy based on site conditions and maintaining consistently high sand-blocking efficiency. Furthermore, by adjusting the windward angle of the sand guide holes, when the wind direction changes vertically, it can play a natural "sand transport" role for the sand accumulated on the leeward side.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0030] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0031] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0032] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this invention is in use. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. In addition, the terms "first," "second," "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0033] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0034] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0035] In existing technologies, the pores of sand-blocking plates cannot be adjusted. When encountering sandstorms with different wind directions and speeds, the sand-blocking plates cannot adaptively adjust their sand-blocking shape, resulting in low sand-blocking efficiency and poor adaptability. Furthermore, the structural design of sand-blocking plates is generally based on maximizing sand-blocking efficiency, and the pore design of the sand-blocking plates is relatively dense, making them prone to being blown over by the wind, thus reducing safety.

[0036] In view of this, the designers have provided a sand-blocking and sand-guiding device suitable for multi-wind-direction Gobi areas. It can adaptively adjust the sand-blocking state according to factors such as wind speed, wind direction, and season. It has diversified functions and high sand-blocking efficiency. It can balance sand blocking and safety, and is not easily blown over by the wind while meeting a high sand blocking rate.

[0037] Please see Figure 1 and Figure 2 In this embodiment, the sand-blocking and sand-guiding device suitable for multi-wind-direction Gobi Desert areas includes a frame 100, multiple spoilers 200, multiple perforated pipes 300, a first solar panel 400, a first drive mechanism 500, and a second drive mechanism 600. The frame 100 has opposing windward and leeward sides. The multiple spoilers 200 are fixed to the frame 100. The multiple perforated pipes 300 are rotatably mounted on the frame 100. The multiple perforated pipes 300 are located below the spoilers 200, and each perforated pipe 300 has a sand-guiding hole 310 to guide sand from the windward side to the leeward side. The first solar panel 400 is slidably connected to the frame 100 and is located on the side of the multiple spoilers 200 away from the leeward side. The first drive mechanism 500 and the second drive mechanism 600 are both mounted on the frame 100. The first drive mechanism 500 is connected to the pore tube 300 and is used to drive the pore tube 300 to rotate in order to adjust the windward angle of the sand guide hole 310. The second drive mechanism 600 is connected to the first solar panel 400 and is used to drive the first solar panel 400 to slide relative to the frame 100.

[0038] Based on the above scheme, the working principle of the sand-blocking and sand-guiding device for multi-wind-direction Gobi areas provided in this embodiment is as follows:

[0039] During operation, when sand is blown towards the windward side of the frame 100, the sand agitates the spoiler fan 200, causing it to rotate and thus agitate the sand, reducing its force and speed. This allows sand particles to fall onto the windward side of the guide hole 310 under the combined action of the spoiler fan 200 and their own weight. This reduces the damage caused by wind to the sand-blocking and guiding device, making the entire system more stable and safer. Simultaneously, the sand particles move from the windward side of the guide hole 310 to the leeward side under the influence of wind, preventing sand from accumulating at the bottom of the frame 100 and blocking the guide hole 310. Furthermore, the angle of the pore tube 300 can be adjusted by the first drive mechanism 500, thereby adjusting the windward angle of the sand guide hole 310. This changes the movement pattern of the sand particles, thus improving the sand-blocking efficiency of existing sand-blocking plates, which is limited by local seasonal wind speed and wind direction changes. The sand-blocking strategy can be adjusted according to the site conditions, maintaining a consistently high sand-blocking efficiency. Moreover, by adjusting the windward angle of the sand guide hole 310, when the wind direction changes vertically, it can naturally "transport" sand accumulated on the leeward side.

[0040] The following embodiments illustrate the detailed structure of the sand-blocking and sand-guiding device for multi-wind-direction Gobi areas provided in this application.

[0041] In this embodiment, an optional sand-blocking and sand-guiding device suitable for multi-wind-direction Gobi desert areas includes a frame 100, multiple spoiler fans 200, multiple pore tubes 300, a first solar panel 400, a first drive mechanism 500, a second drive mechanism 600, a second solar panel 700, a third solar panel 800, an infrared sensor 900, and a sand-clearing mechanism 910. The frame 100 has opposing windward and leeward sides. The multiple spoiler fans 200 are fixed to the frame 100. The multiple pore tubes 300 are rotatably mounted on the frame 100. The multiple pore tubes 300 are located below the spoiler fans 200, and each pore tube 300 has a sand-guiding hole 310 to guide sand from the windward side to the leeward side. The first solar panel 400 is slidably connected to the frame 100, and the first solar panel 400 is located on the side of the multiple spoiler fans 200 away from the leeward side. Both the first drive mechanism 500 and the second drive mechanism 600 are mounted on the frame 100. The first drive mechanism 500 is connected to the pore tube 300 and is used to drive the pore tube 300 to rotate, thereby adjusting the windward angle of the sand guide hole 310. The second drive mechanism 600 is connected to the first solar panel 400 and is used to drive the first solar panel 400 to slide relative to the frame 100. The second solar panel 700 and the third solar panel 800 are located on both sides of the frame 100. The first solar panel 400, the second solar panel 700, and the third solar panel 800 simultaneously provide power to the first drive mechanism 500 and the second drive mechanism 600. The infrared sensor 900 is communicatively connected to the sand cleaning mechanism 910. The infrared sensor 900 is mounted on the frame 100 and is used to detect the sand layer thickness at the bottom of the frame 100. The sand cleaning mechanism 910 is mounted on the bottom of the frame 100 and is used to activate and clean the accumulated sand when the infrared sensor 900 detects that the sand layer thickness is greater than a threshold.

[0042] Optionally, the frame 100 includes two opposing columns 110 and a crossbar 120 connecting the two columns 110. A first solar panel 400 is installed between the two columns 110, and a baffle fan 200 is connected to the crossbar 120. The columns 110 are hollow columns, with an installation channel 130 formed inside for installing wiring harnesses or other components. The wiring harnesses or other components are located inside the columns 110 and are not directly exposed to the external environment, making them less susceptible to damage and extending their service life. The crossbar 120 and the columns 110 can be fixedly connected using fasteners such as screws. There can be multiple crossbars 120, arranged at intervals along the length of the columns 110. For example, in this embodiment, there are four crossbars 120. Obviously, in other embodiments, the number of crossbars 120 is not limited to four. Correspondingly, a row of spoiler fans 200 is installed on each crossbar 120, and multiple spoiler fans 200 in the same row are arranged at intervals along the length of the crossbar 120.

[0043] Meanwhile, multiple spoilers 200 protrude from the pore tube 300 in the direction from the leeward side to the windward side. With this design, after the sand is blocked by the spoilers 200, the sand falls down. The falling sand particles are not likely to fall on the top of the pore tube 300, but instead fall to the bottom of the frame 100 after passing through the pore tube 300. They are less likely to accumulate on the top of the pore tube 300 and affect the angle adjustment of the pore tube 300, thus not affecting the sand blocking efficiency.

[0044] In addition, the top of the pore tube 300 can be set as a sand guiding slope. Even if some sand particles fall on the top of the pore tube 300, they will slide down to the bottom of the windward side of the frame 100 under the action of the sand guiding slope, making it easier to transport them to the leeward side through the pore tube 300.

[0045] Optionally, the second solar panel 700 and the third solar panel 800 are respectively installed on the two columns 110.

[0046] Optionally, the material conveying of the pore tubes 300 consists of multiple tubes arranged in a rectangular array. These multiple pore tubes 300 are arranged in a horizontal row with multiple rows. The multiple pore tubes 300 in the same horizontal row have the same height, and the multiple pore tubes 300 at the same height are connected sequentially along the length of the crossbar 120. In this way, the multiple pore tubes 300 in the same horizontal row form a whole. The first driving mechanism 500 is connected to the side pore tubes 300. By driving the side pore tubes 300 to rotate, the entire row of pore tubes 300 can be driven to rotate, making adjustment convenient and flexible.

[0047] Furthermore, adjacent pore tubes 300 can be connected and fixed by connecting rods. Additionally, a force transmission rod 320 can be provided on the pore tube 300 connected to the first drive mechanism 500 on its side. The force transmission rod 320 is rotatably connected to the frame 100 via bearings. The first drive mechanism 500 includes a first motor 510, a tensioning wheel assembly 520, a transmission bar 530, and a transmission wheel 540. Both the first motor 510 and the tensioning wheel assembly 520 are mounted on the frame 100. The first motor 510 is drive-connected to the tensioning wheel assembly 520. The transmission bar 530 is sleeved around the tensioning wheel assembly 520. The transmission wheel 540 meshes with the transmission bar 530 and is sleeved around and fixedly connected to the force transmission rod 320.

[0048] It should be understood that the number of transmission wheels 540 is equal to the number of rows of pore tubes 300. Each row of pore tubes 300 is paired with one transmission wheel 540, and multiple transmission wheels 540 mesh with transmission bars 530. For example, there can be four rows of pore tubes 300, corresponding to four transmission wheels 540. The transmission bar 530 can be a chain, and the transmission wheels 540 can be sprockets. After the first motor 510 starts, it drives the transmission bar 530 to rotate, thereby driving multiple transmission wheels 540 to rotate together, which in turn drives multiple rows of pore tubes 300 to rotate, adjusting the windward angle of the sand guide holes 310.

[0049] In this embodiment, optionally, a transmission rack 410 is mounted on the first solar panel 400, and the second drive mechanism 600 includes a second motor 610 and a transmission gear 620. The second motor 610 is connected to the frame 100, and the transmission gear 620 is mounted on the output shaft of the second motor 610, meshing with the transmission rack 410. It should be understood that the first motor 510 and the second motor 610 can be connected to two columns 110 respectively, located on both sides of the frame 100. When the first solar panel 400 slides, it can partially block the deflector fan 200, thereby adjusting the deflection effect.

[0050] Optionally, the sand-cleaning mechanism 910 includes a controller, an expansion joint 911, and a sand-cleaning plate 912. The controller is communicatively connected to the expansion joint 911, which is mounted on the frame 100. The sand-cleaning plate 912 is connected to the expansion joint 911. An infrared sensor 900 is communicatively connected to the controller. The expansion joint 911 can be a pneumatic cylinder or a hydraulic cylinder. When the infrared sensor 900 detects that the sand layer at the bottom of the frame 100 is thick, it transmits a signal to the controller. The controller processes the signal and transmits it to the expansion joint 911, which drives the sand-cleaning plate 912 to slide back and forth, thereby cleaning the sand layer.

[0051] In this embodiment, brakeable wheels 920 can also be installed at the bottom of the frame 100.

[0052] The sand-blocking and sand-guiding device for multi-wind-direction Gobi areas provided in this embodiment has at least the following differences:

[0053] (1) This application is designed based on the principles of fluid mechanics and wind and sand physics, and has a certain scientific nature.

[0054] (2) This application can adjust the windward angle, porosity, overall height and windward angle of the sand guide hole 310 according to the seasonal changes of wind speed and wind direction, so as to maximize the sand blocking and wind guiding effect of the sand baffle. At the same time, it can also play a certain role in transporting a small amount of sand accumulated on the leeward side when the wind direction changes vertically.

[0055] (3) The turbulence fan 200 installed in the middle area can play a certain role in ventilation, reduce the pressure of wind on the sand baffle, and ensure the stability of the sand baffle.

[0056] (4) By combining the hydraulic telescopic rod with the detachable sand-clearing plate 912, sand-clearing work on the windward and leeward sides can be completed, saving some manpower.

[0057] (5) The invention is easy to construct, has high sand control efficiency, and is widely applicable, especially suitable for the Gobi Desert windy area.

[0058] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
