Abstract

This utility model relates to the field of sand-fixing equipment technology, and in particular to a basalt fiber composite sand-fixing board. Its technical solution includes multiple basalt fiber boards arranged linearly. This utility model utilizes a sliding mechanism, a connecting mechanism, and a telescopic mechanism. When using the sand-fixing board, the motor is first started to drive the screw rod to rotate, causing the third crossbar to adjust the angle of the V-shaped rod by adjusting the support rod, thereby changing the center of gravity of the device to adapt to different wind and sand intensities. Subsequently, the cylinder is started to drive the top ring to slide, and the middle ring moves synchronously through the V-shaped rotating assembly, adjusting the spacing between the basalt fiber boards. The spacing can be adjusted according to the wind and sand conditions, avoiding increased sand impact due to increased wind speed during strong winds, and preventing the accumulation of flowing sand between the boards during continuous sandstorms, thus reducing the pressure and risk of damage to the boards and improving their adaptability and stability in sand-fixing scenarios.

Description

Technical Field

[0001] This utility model relates to the field of sand fixation equipment technology, and in particular to a basalt fiber composite sand-fixing board. Background Technology

[0002] Basalt fiber is a continuous fiber made from natural basalt rock, melted at 1450-1500℃ and drawn at high speed through a platinum alloy spinneret. Based on this characteristic, basalt fiberboard possesses advantages such as high strength, resistance to high and low temperatures, and corrosion resistance, effectively withstanding wind and sand impacts and extreme climate erosion, making it an ideal material for sand control and stabilization. In existing technologies, these boards are often used to form sand-control devices with supports, fixed to areas requiring protection such as desert edges and transportation routes, utilizing the material's toughness and a reasonable structural design to block shifting sand.

[0003] Currently, basalt fiberboards are typically fixedly installed on supports, resulting in a fixed spacing between the sand-control boards. However, in strong winds carrying sand, if the spacing is too small, the wind speed will accelerate due to the narrowed channel, creating a funneling effect. High-speed flowing sand particles will then cause more intense impact and abrasion on the surface of the sand-control boards, significantly shortening their lifespan and increasing the risk of damage to both the boards themselves and the supporting structure. With continuous sand accumulation, if the spacing is too small, flowing sand can easily clog the spaces between the boards, weakening the ventilation and sand removal capabilities of the sand-control device. Furthermore, the accumulated sand will exert continuous lateral pressure on the boards, potentially leading to board deformation or even the collapse of the entire structure as the sand volume increases. Utility Model Content

[0004] The purpose of this invention is to address the problem that current basalt fiberboards are typically fixedly installed on supports, resulting in a fixed spacing between the boards. However, in strong winds and sand-laden weather, excessively small spacing can easily lead to the basalt fiberboards being subjected to greater pressure from the strong impact of sand particles generated by increased wind speed or the lateral pressure formed by the accumulation of flowing sand, thus increasing the risk of damage. Therefore, this invention proposes a basalt fiber composite material sand-fixing and sand-stabilizing board.

[0005] The technical solution of this utility model is as follows: a basalt fiber composite sand-fixing board, comprising multiple basalt fiber boards arranged in a linear pattern, and further comprising: a connecting mechanism located at the bottom of both ends of the basalt fiber boards, the connecting mechanism being used to drive the multiple basalt fiber boards to synchronously adjust the spacing between them; and a telescopic mechanism disposed on the connecting mechanism to drive the opening and closing of the connecting mechanism.

[0006] Optionally, each of the V-shaped rods has an L-shaped bottom rod at its bottom, and one end of each L-shaped bottom rod is fixedly connected to a vertical bottom rod. The top of each vertical bottom rod is rotatably connected to the bottom of the V-shaped rod. The end of each V-shaped rod away from the vertical bottom rod is rotatably connected to an adjusting support rod. A third crossbar is provided in the middle of the pair of L-shaped bottom rods. Both ends of the third crossbar are slidably sleeved with the L-shaped bottom rods. Both ends of the third crossbar are fixedly connected to the end of the adjusting support rod away from the V-shaped rod. A second crossbar and a fourth crossbar are fixedly installed in the middle of the pair of L-shaped bottom rods. The second, third, and fourth crossbars are provided with a sliding mechanism for adjusting the tilt angle of the V-shaped rod. A vertical top rod is fixedly connected to the V-shaped rod. A fifth crossbar is fixedly connected in the middle of the pair of vertical top rods. A telescopic mechanism for driving the connection mechanism switch is provided in the middle of the fifth crossbar.

[0007] Optionally, the sliding mechanism includes a support box fixedly sleeved in the middle of the fourth crossbar, a motor fixedly connected inside the support box, a helical rod fixedly connected to the output shaft of the motor, a helical sleeve plate fixedly connected to the middle of the third crossbar and helically sleeved with the helical rod, and a boss fixedly connected to the outer wall of the middle of the second crossbar, the top of the boss being rotatably connected to the end of the helical rod away from the support box.

[0008] Optionally, the connecting mechanism includes a bottom ring fixedly sleeved on the bottom end of the V-shaped rod, a top ring slidably connected to the top end of the V-shaped rod, and multiple middle rings with the same spacing slidably connected to the V-shaped rod. The outer walls of the top ring, middle rings and bottom ring are all fixedly connected to corresponding U-shaped seats, and a V-shaped rotating assembly is rotatably connected to a pair of U-shaped seats that are opposite each other.

[0009] Optionally, the outer walls of the top ring, middle ring and bottom ring are all fixedly connected with connecting blocks, and each connecting block is fixedly connected with a U-shaped clamp that holds the end of the basalt fiberboard.

[0010] Optionally, both ends of the basalt fiberboard are provided with locking bolts that are spirally connected to the U-shaped clamp and the connecting block.

[0011] Optionally, the telescopic mechanism includes a sleeve fixedly connected to the middle of the fifth crossbar, a protective cylinder fixedly connected to the sleeve, a cylinder fixedly connected inside the protective cylinder, a connecting crossbar fixedly connected to the middle of a pair of top rings, and the piston rod of the cylinder moving through the protective cylinder and fixedly connected to the middle of the connecting crossbar.

[0012] Optionally, the end of the L-shaped base rod away from the vertical base rod and the bottom end of the vertical base rod are both fixedly connected to concrete foundation piles, and a first horizontal bar is provided at the bottom end of a pair of vertical base rods.

[0015] In summary, this application includes at least one of the following beneficial technical effects:

[0016] This invention utilizes a sliding mechanism, a connecting mechanism, and a telescopic mechanism. When using the sand-stabilizing board, the motor is first started to drive the spiral rod to rotate, causing the third crossbar to rotate the V-shaped rod through the adjusting support rod, thus adjusting the tilt angle of the V-shaped rod and changing the center of gravity of the device to adapt to different wind and sand intensities. Subsequently, the cylinder is started to drive the top ring to slide, and the middle ring moves synchronously through the V-shaped rotating assembly, adjusting the spacing of the basalt fiber boards.

This reduces the pressure and risk of damage to the boards, improving their adaptability and stability in sand control scenarios. Attached Figure Description

[0032] Example

[0033] like Figures 1 to 8 As shown, this utility model proposes a basalt fiber composite sand-fixing board, comprising a pair of L-shaped bottom rods 1 and multiple basalt fiber boards 2 arranged linearly. One end of the L-shaped bottom rod 1 is fixedly connected to a vertical bottom rod 3, and one end of the vertical bottom rod 3 is fixed to the L-shaped bottom rod 1. A V-shaped rod 5 is rotatably connected to the top of the vertical bottom rod 3, and a concrete foundation pile 4 is fixed to the bottom end, serving as a support connecting the bottom structure and the upper V-shaped rod 5. A V-shaped rod 5 is rotatably connected to the top of the vertical bottom rod 3, and the bottom end of the V-shaped rod 5 is rotatably connected to the top end of the vertical bottom rod 3. A vertical top rod 12 is connected to the top, and a top ring 52 and a middle ring 53 are slidably mounted on it. These are key components for installing the basalt fiber boards 2 and adjusting their angle. The adjustable tilt angle of the V-shaped rod 5 allows for greater tilt angle adjustment during strong winds, lowering the center of gravity and bringing it closer to the fixed foundation of the concrete foundation pile 4, thereby enhancing wind and sand resistance and preventing it from being blown over and damaged. Under different wind and sand intensities, the tilt angle of the V-shaped rod 5 is changed to dynamically adjust the center of gravity position, match the load requirements, reduce the risk of structural damage, and thus improve the device's adaptability to complex wind and sand environments. An adjusting support rod 6 is rotatably connected to the end of the V-shaped rod 5 away from the vertical base rod 3. One end of the adjusting support rod 6 is rotatably connected to the end of the V-shaped rod 5 away from the vertical base rod 3, and the other end is fixed to the third crossbar 9, pushing the V-shaped rod 5 to rotate and adjust the angle. A third crossbar 9 is provided in the middle of a pair of L-shaped base rods 1. The two ends of the third crossbar 9 are slidably sleeved with the L-shaped base rods 1, a spiral sleeve plate 91 is fixed in the middle, and both ends are fixed to the adjusting support rod 6. Driven by the spiral rod 103, it slides and pushes the adjusting support rod 6.

[0034] Among them, such as Figure 1 , Figure 3 and Figure 6 As shown, a pair of limiting rings 13 are fixedly connected to each L-shaped base rod 1, which lock the ends of the third crossbar 9. The limiting rings 13 are fixed to the L-shaped base rod 1, locking the ends of the third crossbar 9 and limiting the sliding range of the third crossbar 9. Both ends of the third crossbar 9 are slidably sleeved with the L-shaped base rod 1, and both ends of the third crossbar 9 are fixedly connected to the end of the adjusting support rod 6 away from the V-shaped rod 5. A second crossbar 8 and a fourth crossbar 10 are fixedly installed in the middle of the pair of L-shaped base rods 1. The fourth crossbar 10 is fixed in the middle of the pair of L-shaped base rods 1, and a support box 101 is fixedly sleeved in the middle to provide an installation base for the sliding mechanism. A vertical top rod 12 is fixedly connected to the V-shaped rod 5. A fifth crossbar 11 is fixedly connected in the middle of the pair of vertical top rods 12. The fifth crossbar 11 is fixed in the middle of the pair of vertical top rods 12, and a fixed sleeve 111 is fixed in the middle to provide an installation base for the telescopic mechanism.

[0035] Secondly, such as Figure 1 , Figure 2 and Figure 7 As shown, the second crossbar 8, third crossbar 9, and fourth crossbar 10 are equipped with sliding mechanisms to adjust the tilt angle of the V-shaped rod 5. The sliding mechanisms include a support box 101 fixedly sleeved in the middle of the fourth crossbar 10, with a motor 102 fixedly connected inside the support box 101. The motor 102 is fixed inside the support box 101, and its output shaft is fixed to a helical rod 103, providing power for the rotation of the helical rod 103. The output shaft of the motor 102 is fixedly connected to the helical rod 103. A helical sleeve plate 91, which helically engages with the helical rod 103, is fixedly connected to the middle of the third crossbar 9, converting the rotational motion of the helical rod 103 into the linear motion of the third crossbar 9. A boss 81 is fixedly connected to the outer wall of the middle of the second crossbar 8, with its top rotatably connected to the end of the helical rod 103 away from the support box 101, supporting the rotation of the helical rod 103. The top of the protrusion 81 is rotatably connected to the end of the spiral rod 103 away from the support box 101. A pair of L-shaped bottom rods 1, vertical bottom rods 3, V-shaped rods 5 and adjusting support rods 6 are all symmetrically arranged with the support box 101 as the center.

[0036] In addition, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 8As shown, a connecting mechanism is slidably mounted on the V-shaped rod 5 to synchronously adjust the spacing of the basalt fiberboard 2. The connecting mechanism includes a bottom ring 54 fixedly sleeved on the bottom end of the V-shaped rod 5. The bottom ring 54 is fixedly sleeved on the bottom end of the V-shaped rod 5, and a U-shaped seat 55 and a connecting block 57 are fixed on the outer wall, serving as the bottom fixing point for the installation of the basalt fiberboard 2. A top ring 52 is also slidably connected to the top end of the V-shaped rod 5. The top ring 52 is slidably connected to the top end of the V-shaped rod 5, and a U-shaped seat 55 and a connecting block 57 are fixed on the outer wall. It slides under the action of the connecting crossbar 51 and drives the middle ring 53 to move through the V-shaped rotating assembly 56. Multiple middle rings 53 with the same spacing are slidably connected to the V-shaped rod 5. The middle rings 53 are slidably connected to the V-shaped rod 5 with the same spacing. A U-shaped seat 55 and a connecting block 57 are fixed on the outer wall. They slide synchronously under the action of the top ring 52 to adjust the spacing of the basalt fiberboard 2. The outer walls of the top ring 52, middle ring 53, and bottom ring 54 are all fixedly connected to corresponding U-shaped seats 55. A V-shaped rotating assembly 56 is rotatably connected to each pair of opposing U-shaped seats 55. The V-shaped rotating assembly 56 is rotatably connected to the pair of opposing U-shaped seats 55, transmitting power from the top ring 52 to the middle ring 53, causing all rings to slide synchronously. The V-shaped rotating assembly 56 uses two rod-like structures, with one end of the two rod-like structures rotatably connected, and the other end of each rod-like structure rotatably connected to the corresponding U-shaped seat 55. The outer walls of the top ring 52, middle ring 53, and bottom ring 54 are all fixedly connected to connecting blocks 57. Each connecting block 57 is fixedly connected to a U-shaped clamp 58 that holds the end of the basalt fiberboard 2. The U-shaped clamp 58 is fixed to the connecting block 57, holding the end of the basalt fiberboard 2 in place, and is secured to the fiberboard with locking bolts 59. Both ends of the basalt fiberboard 2 are provided with locking bolts 59 that are spirally connected to the U-shaped clamp 58 and the connecting block 57. The locking bolts 59 spirally connect both ends of the basalt fiberboard 2 to the U-shaped clamp 58 and the connecting block 57, thus firmly fixing the fiberboard.

[0037] It is worth noting that, such as Figure 1 and Figure 5As shown, a telescopic mechanism for driving the connection mechanism switch is provided in the middle of the fifth crossbar 11. The telescopic mechanism includes a sleeve 111 fixedly connected to the middle of the fifth crossbar 11. The sleeve 111 is fixed in the middle of the fifth crossbar 11, and a protective cylinder 112 is fixed on it, supporting and fixing the protective cylinder 112 and the internal cylinder 113. The protective cylinder 112 is fixedly connected to the sleeve 111, and the protective cylinder 112 is fixed on the sleeve 111. The cylinder 113 is fixed inside the sleeve 112, protecting the cylinder 113 and preventing it from sliding. The cylinder 113 is fixedly connected inside the protective cylinder 112. The piston rod is fixed to the connecting crossbar 51, providing driving force for the sliding of the top ring 52. A connecting crossbar 51 is fixedly connected to the middle of a pair of top rings 52, receiving the driving force of the piston rod of the cylinder 113, and driving the top rings 52 to slide along the V-shaped rod 5. The piston rod of cylinder 113 moves through the protective cylinder 112 and is fixedly connected to the middle of the connecting crossbar 51.

[0038] Furthermore, such as Figure 1 and Figure 3 As shown, the end of the L-shaped base rod 1 furthest from the vertical base rod 3 and the bottom end of the vertical base rod 3 are both fixedly connected to concrete piles 4. Concrete piles 4 are generally divided into precast piles and cast-in-place piles. Precast concrete piles are usually prefabricated in a factory and then transported to the site for driving. Cast-in-place concrete piles are formed by drilling holes on the construction site using drilling equipment and then pouring concrete into the holes to form the pile body; this is typically achieved using a drilling and grouting process. The concrete piles 4 are fixed to the end of the L-shaped base rod 1 furthest from the vertical base rod 3 and the bottom end of the vertical base rod 3, firmly fixing the device to the ground and enhancing overall stability. A first horizontal bar 7 is provided at the bottom end of the pair of vertical base rods 3, enhancing the connection stability between the vertical base rods 3.

[0039] In this embodiment, when using the basalt fiber composite sand-fixing device, the L-shaped bottom rod 1 and the vertical bottom rod 3 are first fixed by concrete foundation piles 4 to form a stable foundation for the device. The bottom end of the V-shaped rod 5 is rotatably connected to the top end of the vertical bottom rod 3. The top ring 52 at the top, the middle ring 53 in the middle and the bottom ring 54 at the bottom are all connected by U-shaped seats 55 and V-shaped rotating components 56. The two ends of the basalt fiber plate 2 are fixed to the top ring 52, the middle ring 53 and the bottom ring 54 at the corresponding positions by connecting blocks 57, U-shaped clamps 58 and locking bolts 59.

[0040] Next, the motor 102 inside the support box 101 is started, and its output shaft drives the spiral rod 103 to rotate. The spiral rod 103 is screwed into the spiral sleeve plate 91 in the middle of the third crossbar 9, and the two ends of the third crossbar 9 are restricted from sliding by the limiting rings 13 on the L-shaped bottom rod 1. Then, the third crossbar 9 pushes the V-shaped rod 5 to rotate around the top of the vertical bottom rod 3 by adjusting the support rod 6, thereby adjusting the tilt angle of the V-shaped rod 5 and changing the center of gravity of the device to adapt to different wind and sand intensities.

[0041] Then, the cylinder 113 on the middle sleeve 111 of the fifth crossbar 11 is activated. Its piston rod drives the connecting crossbar 51 and the top ring 52 to slide along the direction of the V-shaped rod 5. The top ring 52 drives the middle ring 53 to slide synchronously through the V-shaped rotating assembly 56, so that the distance between each U-shaped seat 55 changes synchronously, thereby realizing the synchronous spacing adjustment of the basalt fiberboard 2. In this way, the spacing can be increased to disperse the wind force during strong wind and sand weather, improving the adaptability and stability of the device.

[0042] The preferred embodiments of this utility model described above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
