Abstract
Description
Technical Field
[0001] The present disclosure relates to the technical field of windbreak and sand fixation, and in particular, to a sand barrier system and a photovoltaic power station. Background Art
[0002] Sand barriers are made of firewood, straw, clay, branches, laths, pebbles and other materials on the sand surface. They are effective engineering sand fixation measures to reduce wind speed and fix the sand surface. Based on this, sand barriers can reduce the erosion of sand and dust on equipment. At present, sand barriers generally use the method of setting straw grids or drip irrigation around the fixed piles of the equipment to fix the quicksand and block the external wind and sand. However, the degradation rate of the separately set straw grids or drip irrigation plants is relatively fast, which makes the sand barriers unable to effectively protect the fixed piles of the equipment after a period of use, thus affecting the normal use of the equipment. Utility Model Content

DETAILED DESCRIPTION
[0022] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.
[0023] In the present disclosure, unless otherwise specified, the directional words used, such as "inside" and "outside", refer to the "inside" and "outside" relative to the corresponding component's own contour. In addition, in the following description, when referring to the drawings, unless otherwise specified, the same reference numerals in different drawings represent the same or similar elements. The above definitions are only used to explain and illustrate the present disclosure and should not be understood as limiting the present disclosure.
[0024] The sand barrier system in an exemplary embodiment of the present disclosure will be described below with reference to the accompanying drawings.
[0025] refer to Figures 1 to 3 As shown, in the first aspect of the present disclosure, a sand barrier system is provided, including a gravel sand barrier layer 1, a high vertical sand barrier layer 3 and an intermediate sand barrier layer 2. The gravel sand barrier layer 1 is arranged on the fixed piles 5 of the equipment, and the intermediate sand barrier layer 2 is arranged on the outer peripheral side of the gravel sand barrier layer 1 and is located between the gravel sand barrier layer 1 and the high vertical sand barrier layer 3. Since the fixed piles 5 are directly buried under the ground, the outer peripheral side of the fixed piles 5 is the area most severely affected by sand erosion, and the gravel in the gravel sand barrier layer 1 forms many small irregular surfaces on the sand, which increases the roughness of the sand surface while increasing the resistance encountered by the wind when blowing through this place, thereby reducing the wind speed and reducing the wind force here, preventing the wind from being too strong and driving the sand and dust to flow and erode the fixed piles 5; in addition, after the gravel is laid on the sand, it can not only block the path of the sand and dust flowing with the wind, but also enable part of the sand and dust located on the side of the fixed piles 5 to be pressed by the gravel, thereby slowing down the flow of sand and dust, and further reducing the impact of the sand and dust flow on the fixed piles 5; the intermediate sand barrier layer 2 is arranged on the outer peripheral side of the gravel sand barrier layer 1, which can stabilize the sand and dust in the area near the fixed piles 5 and prevent the flow of sand and dust in this area from eroding the fixed piles 5; the high vertical sand barrier layer 3 located in the outermost layer can block the external sand and dust flowing and floating with the wind to a certain extent, and prevent the external sand and dust from eroding the intermediate sand barrier layer 2, the gravel sand barrier layer 1 and the fixed piles 5. Based on this, the multi-sand barrier layer structure formed by the gravel sand barrier layer 1, the intermediate sand barrier layer 2 and the high vertical sand barrier layer 3 can reduce the erosion of the fixed piles 5 and the sand barrier layer near the fixed piles 5 by the flow of sand and dust, thereby enhancing the sand fixation and sand prevention effects of the entire sand barrier system and increasing the service life of the sand barriers and the fixed piles 5.
[0026] It should be noted that the fixing pile 5 of the present disclosure may be a columnar structure connected to a photovoltaic panel 4, a distribution box or other device.
[0027] In some embodiments of the present disclosure, the middle sand barrier layer 2 includes wheat straw 201 partially buried below the ground and reinforcing rods 202. Although the wheat straw 201 buried alone in the ground can also slow down the flow of sand and dust to a certain extent, the wheat straw 201 itself is relatively soft and will be greatly affected by wind and sand, so its life is relatively short, and the staff needs to replace the wheat straw 201 for a long time to keep the sand fixation effect. Based on this, the middle sand barrier layer 2 of the present disclosure is also provided with reinforcing rods 202 with higher hardness, so as to have a certain protective effect on the wheat straw 201 while fixing the sand, reduce the impact of wind and sand on the wheat straw 201, and increase the service life of the middle sand barrier layer 2.
[0028] Among them, Figure 3 As shown, the reinforcing rod 202 can be arranged on the outer peripheral side of the straw 201 to build a relatively stable protective structure around the straw 201, thereby reducing the flow of sand and dust around the straw 201, thereby reducing the impact of sand and dust on the straw 201 and improving the life of the straw 201. Of course, the reinforcing rod 202 can also be inserted into the straw 201, so that the reinforcing rod 202 can work together with the straw 201 to reduce the flow of sand and dust while ensuring the protective effect on the straw 201. It should be noted that the reinforcing rod 202 of the present disclosure can be configured as a hard rod-shaped structure such as a wooden stick or an iron stick.
[0029] In some embodiments, the middle sand barrier layer 2 includes a transverse sand barrier layer 203 and a longitudinal sand barrier layer 204 , and the transverse sand barrier layer 203 and the longitudinal sand barrier layer 204 are staggered to form a checkered sand barrier 205 . The checkered sand barrier 205 can increase the roughness of the surface around the equipment to a certain extent, slow down the flow of sand and dust around the equipment, and prevent the flowing sand and dust from affecting the fixed piles 5 of the equipment. It should be noted that different types of checkered sand barriers 205 have other advantages in addition to increasing the surface roughness. For example, the checkered sand barrier 205 can be a straw checkered sand barrier. The straw checkered sand barrier can not only intercept the condensation water generated by the temperature difference between day and night, so that the condensation water can infiltrate and increase the water content of the soil, but also increase the organic matter in the soil to facilitate the planting of sand-fixing plants in the checkered sand barrier 205; or, the checkered sand barrier 205 can also be a gravel checkered sand barrier. The gravel checkered sand barrier has a longer service life and does not need to be replaced frequently; or, the checkered sand barrier 205 can be composed of the above-mentioned wheat straw 201 and reinforcing rods 202 to improve its service life on the basis of the wheat straw grid.
[0030] Among them, the number of the checkered sand barriers 205 can be configured in multiple, and multiple adjacent checkered sand barriers 205 form an intermediate sand barrier layer 2, and at least one checkered sand barrier 205 is paved with a vegetation layer 206. Multiple checkered sand barriers 205 can enhance the overall protection effect of the intermediate sand barrier layer 2. It should be noted that the size of the checkered sand barriers 205 can also be adaptively adjusted according to the on-site conditions, including but not limited to a checkered sand barrier 205 with a size of 1m×1m. In addition, laying a vegetation layer 206 in the checkered sand barrier 205, that is, sand-fixing plants that can survive in harsh environments, such as Caragana korshinskii, Caragana scabra, Artemisia ordosica, Calligonum sphaerocephala, etc., can make the sand barrier system degrade, and the sand-fixing plants can still prevent the flow of sand and dust, and prevent the erosion of nearby equipment and fixed piles 5 by quicksand.
[0031] In an embodiment of the present disclosure, the gravel sand barrier layer 1 is laid extending outward from the circumference of the fixed pile 5, wherein the extension length of the gravel sand barrier layer 1 can be 50 cm to protect the areas with the most serious erosion around the equipment and the fixed pile 5. Of course, according to different equipment and the differences in the structure of the fixed pile 5 itself, the laying length of the gravel sand barrier layer 1 can be adaptively changed, and the present disclosure does not limit this.
[0032] In some embodiments, the heights of the gravel sand barrier layer 1, the middle sand barrier layer 2, and the high vertical sand barrier layer 3 are increased in sequence. The high vertical sand barrier layer 3 has the highest height and is set at the outermost layer of the sand barrier system. It can be made of high-density polyethylene material, or it can be made of reed bundles, nylon nets, cotton sandbags, etc., so as to block the external wind and sand from entering the setting area of the equipment to a certain extent, that is, to reduce the input of external wind and sand, and play the role of protecting the equipment and its fixed piles 5. Among them, the height of the high vertical sand barrier layer 3 exposed to the ground is 1.2-1.8m. The high vertical sand barrier layer 3 within this height range can avoid the situation where the sand barrier is too low to effectively block sand and dust from entering the sand barrier system or the sand barrier is too high and the stability is poor. Of course, in areas with large terrain undulations, the height of the high vertical sand barrier layer 3 is Appropriate adjustments can be made; the intermediate sand barrier layer 2 is located between the gravel sand barrier layer 1 and the high vertical sand barrier layer 3, and the height is also between the two, which can form a semi-hidden sand barrier layer to achieve the effect of sand fixation and prevent the flowing sand and dust from eroding the equipment and the fixed piles 5, wherein the intermediate sand barrier layer 2 is buried at a depth of 20-25cm below the ground and exposed to the ground at a height of 20-25cm. The intermediate sand barrier layer 2 within this height range can reduce the investment cost while playing a role in sand fixation, so as to ensure the stability and economy of the intermediate sand barrier layer 2; the gravel sand barrier layer 1 closest to the fixed piles 5 protects the areas with the most serious erosion around the equipment and the fixed piles 5.
[0033] The second aspect of the present disclosure provides a photovoltaic power station, which includes a photovoltaic panel 4 and the above-mentioned sand barrier system, and the photovoltaic panel 4 is provided with a fixing pile 5, and the fixing pile 5 is inserted into the ground. On the one hand, the photovoltaic panel 4 can form a rain collecting surface to play a role in soil moisture conservation, and on the other hand, the shadow formed by it can also effectively reduce the ground temperature, thereby reducing the evaporation of ground water, which is conducive to the growth of sand-fixing plants, that is, the photovoltaic power station can work together with the sand barrier system to slow down the flow of sand and dust, prevent sand and dust from eroding itself, and increase its service life.
[0034] In summary, the present disclosure exemplarily illustrates the working principle of the sand barrier system.
[0035] The high vertical sand barrier layer 3 at the outermost side of the sand barrier system can block part of the external sand and dust, thereby reducing the sand content in the sand barrier system and preventing excessive sand and dust from flowing in the sand barrier system and eroding the gravel sand barrier layer 1, the middle sand barrier layer 2 and the fixed piles 5. The middle sand barrier layer 2 formed by a plurality of square sand barriers 205 can slow down the flow of sand and dust around the equipment and the fixed piles 5. The middle sand barrier layer 2 is composed of wheat straw 201 and reinforcing rods 202. The reinforcing rods 202 can reduce the erosion of the wheat straw 201 by the quicksand while fixing the sand, thereby increasing the service life of the wheat straw 201. The gravel sand barrier layer 1 arranged on the outer peripheral side of the fixed pile 5 can increase the roughness of the sand surface while increasing the resistance encountered by the wind when blowing through this place, thereby reducing the wind speed and the wind force here, and preventing the excessive wind force from driving the sand and dust to flow and erode the fixed pile 5. Based on this, the multi-sand barrier layer structure formed by the gravel sand barrier layer 1, the intermediate sand barrier layer 2 and the high vertical sand barrier layer 3 disclosed in the present invention can reduce the erosion of the fixed pile 5 and the sand barrier layer near the fixed pile 5 by the flow of sand and dust, thereby enhancing the sand fixation and sand prevention effect of the entire sand barrier system and increasing the service life of the sand barrier and the fixed pile 5.

Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.
[0037] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.
[0038] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
