Description

Technical Field

[0001] This invention relates to the field of desert control equipment technology, and in particular to a photovoltaic sand control retaining wall. Background Technology

[0002] Desertification control is a significant ecological and environmental problem, and mechanical sand-blocking walls are a common method of combating sandstorms. In recent years, combining solar photovoltaic power generation with sand-control structures, utilizing the shading effect of photovoltaic panels to reduce water evaporation and provide clean electricity, has become an important development direction for desert ecological governance.

[0003] However, traditional sand-retaining wall structures typically employ fixed mesh panels or woven branches, meaning their permeability cannot be altered once installed. Desert weather is complex and unpredictable, and a fixed permeability cannot be flexibly adjusted according to actual wind conditions. In extreme winds, insufficient permeability can cause the sand-retaining wall to withstand immense lateral wind pressure, easily leading to structural deformation or collapse. Conversely, in everyday conditions with relatively low wind speeds but carrying large amounts of fine sand, excessive permeability prevents the sand-retaining wall from effectively intercepting and depositing sand and dust.

[0004] Furthermore, as the sand-blocking wall continues to function, sand particles accumulate at its base, causing the surrounding sand level to rise continuously. Existing photovoltaic sand-blocking devices are typically fixed directly to the ground foundation, lacking an adaptive adjustment mechanism for height. Over time, the fixed-height wall structure is easily buried by the rising sand, blocking the original ventilation openings and causing the entire sand control system to completely lose its windbreak and sand-fixing function. Summary of the Invention

[0005] The purpose of this invention is to provide a photovoltaic sand control barrier wall to alleviate the problems of fixed air permeability and fixed height in existing sand control walls, which cannot be flexibly adjusted.

[0006] To solve the above-mentioned technical problems, the technical solution provided by the present invention is as follows: A photovoltaic sand control and sand-retaining wall includes: a support column, a ventilation adjustment component, and a height adjustment component. The support column is arranged vertically, the ventilation adjustment component is slidably connected to the support column, and the height adjustment component is disposed at the bottom of the ventilation adjustment component. The height adjustment component is used to adjust the height of the ventilation adjustment component from the ground. The ventilation adjustment component includes a drive component, a transmission component, and a baffle blade. The drive component is connected to the baffle blade through the transmission component. The drive component can drive the baffle blade to rotate through the transmission component to adjust the tilt angle of the baffle blade.

[0007] Furthermore, the ventilation adjustment assembly also includes a baffle frame, the interior of which is provided with a mounting cavity, and the drive component and the transmission assembly are disposed in the mounting cavity.

[0008] Furthermore, the driving component includes a motor, the transmission assembly includes a gear mechanism and a rotating shaft, the output end of the motor is connected to the gear mechanism, the gear mechanism is drivenly connected to one end of the rotating shaft, the other end of the rotating shaft is rotatably connected inside the support column, and the baffle blade is fixedly connected to the outside of the rotating shaft.

[0009] Furthermore, the gear mechanism includes an intermediate gear and side gears meshing with both sides of the intermediate gear. The intermediate gear is connected to the output end of the motor, and the two side gears are rotatably connected to their respective rotating shafts.

[0010] Furthermore, the ventilation adjustment component also includes a side strip, which is fixedly connected to the inner side of the baffle outer frame and is located at the upper and lower ends of the baffle blade.

[0011] Furthermore, the height adjustment assembly includes a first height adjustment part, which includes an electric push rod and a slider. The output end of the electric push rod is connected to the bottom of the baffle outer frame, and the slider is disposed on both sides of the baffle outer frame and is slidably connected to the support column.

[0012] Furthermore, the height adjustment assembly also includes a second height adjustment section, which is disposed at the bottom of the first height adjustment section, and the electric push rod is disposed in the second height adjustment section.

[0013] Furthermore, the second height adjustment part includes an adjustable crossbeam, a fixing structure, and an adjustment structure. The two ends of the adjustable crossbeam are respectively connected to the two support columns. The electric push rod is installed on the top of the adjustable crossbeam. The fixing structure includes a fixing block and a fastening bolt. The fixing block is fixedly connected to both ends of the adjustable crossbeam. The adjustment structure is disposed on the support column. The fastening bolt passes through the fixing block and the adjustment structure and is threadedly connected to the support column.

[0014] Furthermore, the adjustment structure includes a plurality of adjustment holes spaced apart along the height direction at the bottom of the support column, and the fastening bolts pass through the fixing block and the adjustment holes to fix the adjustable crossbeam to the support column.

[0015] Furthermore, a photovoltaic panel is fixedly connected to the top of the support column, and the photovoltaic panel is located directly above the ventilation and adjustment component.

[0016] This invention can bring at least the following beneficial effects: The photovoltaic sand control and retaining wall provided by the present invention includes: a support column, a ventilation adjustment component, and a height adjustment component. The support column is arranged vertically, the ventilation adjustment component is slidably connected to the support column, and the height adjustment component is disposed at the bottom of the ventilation adjustment component. The height adjustment component is used to adjust the ground height of the ventilation adjustment component. The ventilation adjustment component includes a driving component, a transmission component, and baffle blades. The driving component is connected to the baffle blades through the transmission component, and the driving component can drive the baffle blades to rotate through the transmission component to adjust the tilt angle of the baffle blades.

[0017] The driving component drives the baffle blades to rotate through the transmission assembly, thereby adjusting the tilt angle of the baffle blades and realizing the dynamic adjustment of the ventilation rate of the photovoltaic sand control sand barrier wall. This solves the problem that the ventilation rate of the sand barrier wall is fixed in the existing technology and cannot be adapted to different wind and sand weather environments. It achieves the technical effect of dynamically adjusting the wind resistance according to the actual wind force and effectively balancing the structural safety under strong wind conditions and the high efficiency of sand blocking under normal conditions.

[0018] By sliding the ventilation adjustment component to the support column and setting a height adjustment component at the bottom of the ventilation adjustment component, the height adjustment component can drive the ventilation adjustment component to slide along the support column, and can adaptively adjust the height of the ventilation adjustment component from the ground. This solves the problem in the prior art that fixed sand retaining walls are easily buried by sand as the desert sand accumulates and rises, causing equipment failure.

[0028] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0029] Example 1 This invention provides a photovoltaic sand control barrier wall, which aims to solve the technical problems of existing sand control walls having a fixed air permeability that cannot adapt to different wind and sand environments, and the structure being easily buried after the sand surface rises, leading to equipment failure.

[0030] See Figures 1 to 6 The photovoltaic sand control retaining wall includes: a support column 1, a ventilation adjustment component 2, and a height adjustment component 3. The support column 1 is set vertically, the ventilation adjustment component 2 is slidably connected to the support column 1, and the height adjustment component 3 is set at the bottom of the ventilation adjustment component 2. The height adjustment component 3 is used to adjust the height of the ventilation adjustment component 2 from the ground. The ventilation adjustment component 2 includes a driving component, a transmission component, and a baffle blade 205. The driving component is connected to the baffle blade 205 through the transmission component. The driving component can drive the baffle blade 205 to rotate through the transmission component to adjust the tilt angle of the baffle blade 205.

[0031] The driving component drives the baffle blade 205 to rotate through the transmission assembly, thereby adjusting the tilt angle of the baffle blade 205 and realizing the dynamic adjustment of the ventilation rate of the photovoltaic sand control barrier wall. This solves the problem that the ventilation rate of the sand control barrier wall is fixed in the existing technology and cannot be adapted to different wind and sand weather environments. It achieves the technical effect of dynamically adjusting the wind resistance according to the actual wind force and effectively balancing the structural safety under strong wind conditions and the high efficiency of sand blocking under normal conditions.

[0032] By sliding the ventilation adjustment component 2 to the support column 1, and setting the height adjustment component 3 at the bottom of the ventilation adjustment component 2, the height adjustment component 3 can drive the ventilation adjustment component 2 to slide along the support column 1, and can adaptively adjust the height of the ventilation adjustment component 2 off the ground. This solves the problem in the prior art that fixed sand retaining walls are easily buried by sand as the desert sand accumulates and rises, causing equipment failure.

[0033] See Figure 1 and Figure 2The support column 1 serves as the load-bearing framework and guide base for the entire device, its base anchored in the desert ground to provide a stable physical support platform. The main body of the support column 1 is made of high-strength, corrosion-resistant metal material, effectively resisting long-term erosion and wear from wind and sand. The ventilation adjustment component 2 is used to adjust the ventilation openings of the sand retaining wall to dynamically adapt to sandstorms of varying intensities; the height adjustment component 3 is used to adjust the overall height of the ventilation adjustment component 2 above the ground to prevent excessive sand burial and ensure the normal operation of the mechanical structure.

[0034] In an optional embodiment, the ventilation adjustment component 2 further includes a baffle frame 201, the interior of which is provided with a mounting cavity 202, and the driving component and transmission component are disposed in the mounting cavity 202.

[0035] See Figure 4 and Figure 5 The baffle frame 201 has a rectangular frame structure, and its dimensions match the span between the support column 1. The baffle frame 201 provides a completely enclosed assembly environment for the internal transmission components, preventing fine dust from entering the core mechanical area and causing wear or jamming. The mounting cavity 202 is used to accommodate the drive components and transmission components and provides sufficient space for lubrication and heat dissipation.

[0036] In an optional embodiment, the driving component includes a motor 207, and the transmission assembly includes a gear mechanism 203 and a rotating shaft 204. The output end of the motor 207 is connected to the gear mechanism 203, and the gear mechanism 203 is connected to one end of the rotating shaft 204. The other end of the rotating shaft 204 is rotatably connected inside the support column 1, and a baffle blade 205 is fixedly connected to the outside of the rotating shaft 204.

[0037] See Figure 5 The motor 207 provides the power to drive the rotation. The motor 207 is a high-torque stepper motor or servo motor to ensure stable output of deflection power even under extremely high wind loads. The gear mechanism 203 is used for power transmission and precise distribution, and the shaft 204 supports and drives the baffle blades 205 to deflect synchronously. The baffle blades 205 are made of high-strength and lightweight metal or composite materials, and their surface is treated with anti-static spraying to prevent sand particles from adsorbing and accumulating. The streamlined cross-sectional design of the baffle blades 205 effectively reduces air resistance and, when closed, interlocks to form a robust physical windbreak barrier, thus providing safe protection for vegetation growth or transportation routes in leeward areas during sandstorms.

[0038] In an optional embodiment, the gear mechanism 203 includes an intermediate gear and side gears meshing with both sides of the intermediate gear. The intermediate gear is connected to the output end of the motor 207, and the two side gears are rotatably connected to the corresponding rotating shafts 204.

[0039] See Figure 5 In actual transmission, when motor 207 receives a control signal and starts running, the output shaft of motor 207 directly drives the intermediate gear to rotate. When the intermediate gear rotates, the meshing force between the gear teeth drives the two side gears to rotate synchronously and in the same direction, thereby changing the tilt angle of the baffle blades 205. This mechanical transmission layout based on the meshing of rigid gears not only effectively avoids the aging and slippage phenomenon that belt drives are prone to under extreme temperature differences, but also can change the operating posture of all baffle blades 205 with extremely high control precision. This allows the ventilation adjustment component 2 to freely switch between fully open ventilation, half-open sand blocking, and fully closed windproof states based on the real-time monitored wind speed data. This ensures that the sand-blocking wall can unload wind pressure and protect its own structural safety by increasing the ventilation rate in strong winds, and intercept fine sand particles suspended in the air and promote their settling by reducing the ventilation rate in light winds.

[0040] In an optional embodiment, the ventilation adjustment component 2 further includes a side strip 206, which is fixedly connected to the inner side of the baffle outer frame 201 and is located at the upper and lower ends of the baffle blade 205.

[0041] See Figure 5 The edge strip 206 is made of rubber or silicone material with excellent weather resistance and high elasticity. The edge strip 206 is used to fully fill the upper and lower gaps when the baffle blades 205 are driven by the motor 207 to the fully closed state, thereby improving the overall structure's windproof and sandproof sealing performance. Since the baffle blades 205 must maintain a small gap with the inner wall of the baffle outer frame 201 during rotation to prevent structural jamming, and these gaps often become penetration channels for high-speed sand-laden airflow, the edge strip 206 compensates for this structural shortcoming. When the baffle blades 205 are closed, their edge contours are tightly pressed against the surface of the edge strip 206 to form an interference fit, thereby maximizing the isolation of sand and dust penetration and improving the protective quality and service life of the sand retaining wall under the extreme climate of the desert.

[0042] In an optional embodiment, the height adjustment component 3 includes a first height adjustment part, which includes an electric push rod 304 and a slider 306. The output end of the electric push rod 304 is connected to the bottom of the baffle outer frame 201, and the slider 306 is disposed on both sides of the baffle outer frame 201 and is slidably connected to the support column 1.

[0043] See Figure 3 and Figure 6The output end of the electric push rod 304 is fixedly connected to the bottom of the baffle outer frame 201. The electric push rod 304 provides longitudinal lifting power to push the baffle outer frame 201 to make fine adjustments in the vertical direction. The slider 306 is fixedly connected to both sides of the baffle outer frame 201. The inside of the support column 1 is provided with a sliding groove along the vertical direction. In the assembled state, the slider 306 slides in the sliding groove. This structure plays a limiting and guiding role, ensuring the high stability and anti-deflection ability of the baffle outer frame 201 during the process of being lifted or lowered by the electric push rod 304, thereby driving the ventilation adjustment component 2 to rise and fall smoothly as a whole.

[0044] The power control source for the movement of the drive motor 207 and the electric push rod 304 can be achieved by those skilled in the art using conventional control switches and power supply lines. The specific electrical control structure is well-known in the field and will not be described in detail here.

[0045] In an optional embodiment, the height adjustment component 3 further includes a second height adjustment part, which is disposed at the bottom of the first height adjustment part, and the electric push rod 304 is disposed in the second height adjustment part.

[0046] Specifically, the second height adjustment unit includes an adjustable crossbeam 301, a fixing structure, and an adjustment structure. The two ends of the adjustable crossbeam 301 are respectively connected to two support columns 1. An electric push rod 304 is installed on the top of the adjustable crossbeam 301. The fixing structure includes a fixing block 305 and a fastening bolt 302. The fixing block 305 is fixedly connected to both ends of the adjustable crossbeam 301. The adjustment structure is set on the support column 1. The fastening bolt 302 passes through the fixing block 305 and the adjustment structure and is threadedly connected to the support column 1.

[0047] In an optional embodiment, the adjustment structure includes multiple adjustment holes 303 spaced apart at the bottom of the support column 1 along the height direction. The fastening bolts 302 pass through the fixing block 305 and the adjustment holes 303 to fix the adjustable beam 301 to the support column 1.

[0048] See Figure 6 When the sand surface is raised too high, the fastening bolts 302 can be loosened to move the fixing block 305 and the adjustable crossbeam 301 upwards to the corresponding adjustment hole 303. Then, the fastening bolts 302 can be tightened again to complete the fixation, thereby achieving a large range of raising of the height adjustment component 3 to avoid sand burial affecting the normal operation of the ventilation adjustment component 2. The cooperation between the adjustment hole 303 and the fastening bolts 302 forms a stable mechanical locking structure to support the overall weight of the upper ventilation adjustment component 2.

[0049] In an optional embodiment, a photovoltaic panel 4 is fixedly connected to the top of the support column 1, and the photovoltaic panel 4 is located directly above the ventilation adjustment component 2.

[0050] See Figure 2 The photovoltaic panel 4 is fixedly connected to the top surface of the support column 1 by fasteners, and is located directly above the ventilation and adjustment component 2. The photovoltaic panel 4 not only absorbs abundant solar energy resources to generate electricity in an environmentally friendly manner and converts it into electrical energy stored in the battery, providing a continuous source of clean energy for the entire control system and the operation of the motor 207, but also provides top shading protection for the mechanical operating devices at the bottom and blocks the vertically falling sand and dust. The top fixed support structure formed by the photovoltaic panel 4 and the support column 1 further enhances the compressive strength of the overall frame of the sand retaining wall and improves spatial stability.

[0051] The following explains the working principle of the photovoltaic sand control and sand-retaining wall: When the windy and sandy weather changes and the ventilation openings need to be adjusted, the motor 207 is started. The output of the motor 207 drives the intermediate gear to rotate. The intermediate gear, through meshing transmission, drives the upper and lower gears to rotate synchronously in the same direction, which in turn drives the rotating shaft 204 to rotate. The rotating shaft 204 drives the baffle blades 205 fixedly connected to the outside to deflect synchronously. By changing the tilt angle of the baffle blades 205, the airflow passing through the sand-blocking wall is precisely adjusted. When the wind and sand are too strong and complete closure is required, the baffle blades 205 deflect to a state of contact with the edge strip 206. The edge strip 206 fills the gaps at the upper and lower ends of the baffle blades 205 to achieve windproof and sandproof sealing.

[0052] When the sand surface gradually rises and requires fine-tuning of the ground clearance, the electric push rod 304 is activated. The output end of the electric push rod 304 extends upward or retracts downward, driving the upper baffle frame 201 to move. During the lifting or lowering process, the slider 306 slides up and down along the groove, strictly limiting the movement trajectory to the preset path. This guiding structure effectively resists the lateral force on the windward side of the sand retaining wall, thereby preventing the baffle frame 201 from deflecting or swaying during the lifting and lowering process, and thus driving the ventilation adjustment component 2 to rise and fall smoothly as a whole.

[0053] When the desert terrain experiences significant subsidence or the sand surface rises excessively beyond the travel of the electric push rod 304, the fastening bolt 302 can be manually loosened, and the fixing block 305, together with the adjustable crossbeam 301, can be moved up along the support column 1 to the corresponding adjustment hole 303. The fastening bolt 302 can then be tightened again to complete a large-scale height reset.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
