[0002] Northwest China is located in the East Asian Dust Storm Zone, one of the four major sandstorm zones in the world. It is one of the areas with the most serious wind and sand disasters in my country. The seven deserts and five wind zones in the region provide conditions for the occurrence of sandstorms. The sand carried by strong winds will cause serious erosion to the concrete foundation of photovoltaic facilities. Concrete structures often produce erosion cracks, cement block peeling and other damage phenomena under the erosion of wind and sand, resulting in a continuous decrease in concrete strength, aggravating the failure of concrete structures, and seriously reducing the durability of concrete structures, making the actual life of photovoltaic facility foundations far less than the designed service life.
[0003] Although common methods such as directly sticking iron sheets on the outer wall of the photovoltaic foundation can alleviate the harm of wind and sand erosion, the surface iron sheets will debond from the concrete after direct exposure to ultraviolet rays and rain erosion, causing the iron sheets to fall off, increasing maintenance costs, and the protective effect cannot meet actual needs.

[0004] In view of the above problems, the utility model proposes a wind and sand erosion protection device for photovoltaic foundations in desert areas, comprising: a sleeve, a first sleeve member and a second sleeve member;
[0005] A through hole is provided on the sleeve, and the first sleeve member and the second sleeve member are arranged symmetrically about the through hole to form an enclosed space. The first sleeve member is fixedly connected to the sleeve, and a sliding groove is provided on the sleeve. The lower end of the second sleeve member is slidably connected to the sliding groove. The enclosed space can be reversibly converted into a semi-enclosed space by changing the position of the second sleeve member along the sliding groove.
[0006] Furthermore, the first sleeve member and the second sleeve member both adopt an annular cylindrical structure with a semicircular cross-section, and the radius of the outer side wall of the first sleeve member is smaller than the radius of the inner side wall of the second sleeve member.
[0007] Furthermore, the slide groove adopts an annular structure, and the slide groove and the through hole are coaxially arranged.

[0010] The second sleeve member specifically comprises: a second lower cylinder member, a second upper cylinder member slidably sleeved with the inner wall of the second lower cylinder member, the inner wall of the second lower cylinder member is provided with a driving gear at both the front and rear ends, and the front and rear end side walls of the second upper cylinder member are provided with a rack portion, and the rack portions of the second lower cylinder member are respectively corresponding to each other and meshed with the driving gear of the second lower cylinder member;
[0011] The drive gears are all electrically connected to the remote controller.

[0016] Furthermore, the outer walls of the sleeve, the first sleeve member and the second sleeve member are all provided with an anti-aging coating.
[0017] The utility model provides a wind and sand erosion protection device for photovoltaic foundations in desert areas. Facing a photovoltaic foundation mostly made of concrete, the photovoltaic foundation is firstly surrounded by a first sleeve member and a second sleeve member to directly block the surrounding wind and sand.

DETAILED DESCRIPTION
[0024] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] The utility model provides a wind and sand erosion protection device for photovoltaic foundations in desert areas. Figure 1 The cross-sectional structure diagram of the wind and sand erosion protection device for photovoltaic foundations in desert areas in the embodiment of the utility model is shown. Figure 2 In the embodiment, the wind and sand erosion protection device for photovoltaic foundation in desert area comprises: a sleeve 1, a first sleeve member 2 and a second sleeve member 3, wherein, according to the photovoltaic foundation in desert area is mostly cylindrical and rectangular, a through hole 4 is opened on the sleeve 1, and the inner diameter of the through hole 4 is greater than Photovoltaic Basics The diameter of the photovoltaic foundation is symmetrically arranged on the left and right sides of the through hole 4. When the sleeve 1 is installed on the ground and the photovoltaic foundation is sleeved in the through hole 4, the first sleeve 2 and the second sleeve 3 arranged on the left and right sides can surround the photovoltaic foundation, thereby forming an enclosed space for accommodating the photovoltaic foundation, thereby protecting the side wall of the photovoltaic foundation, blocking the wind and sand in the external environment, and preventing the erosion of the photovoltaic foundation by the external wind and sand.
[0026] At the same time, the first sleeve member 2 is fixedly connected to the sleeve seat 1, and a slide groove 13 is provided on the sleeve seat 1. The lower end of the second sleeve member 3 is slidably connected to the slide groove 13, that is, the second sleeve member 3 can change its position along the slide groove 13, thereby changing the relative position of the second sleeve member 3 and the first sleeve member 2, thereby realizing the change of the above-mentioned enclosed space. The enclosed space is converted into a semi-enclosed space by the second sleeve member 3 changing its position along the slide groove 13. At the same time, the semi-enclosed space is converted into an enclosed space by the second sleeve member 3 changing its position along the slide groove 13.
[0027] In actual use, the utility model faces a photovoltaic foundation which is mostly made of concrete. First, the photovoltaic foundation is surrounded by the first sleeve member 2 and the second sleeve member 3 to directly block the surrounding wind and sand. At the same time, the first sleeve member 2 and the second sleeve member 3 are spaced apart from the photovoltaic foundation, so that the high temperature on the first sleeve member 2 and the second sleeve member 3 cannot be directly radiated to the photovoltaic foundation. The photovoltaic equipment installed above the photovoltaic foundation will form a sunshade area on the photovoltaic foundation. The temperature of the sunshade area will be significantly lower than the temperature near the ground and inside the protective device, so that the cold airflow above the protective device and the hot airflow inside the protective device form convection, thereby improving the heat dissipation effect inside the protective device, avoiding the influence of external high temperature on the thermal radiation of the photovoltaic foundation, and improving the protective effectiveness of the photovoltaic foundation.
[0028] At the same time, since the top of the enclosed space does not adopt a fully enclosed structure, a small amount of wind and sand will float in from the top and fill the enclosed space. Therefore, the present application uses a second sleeve member 3 that can slide to change its position to form a reversible conversion between the enclosed space and the semi-enclosed space. After the wind and sand accumulate in the protective device, the second sleeve member 3 can be directly rotated to allow the wind and sand in the protective device to flow out from the gap.
[0029] Specifically, the first sleeve member 2 and the second sleeve member 3 both adopt an annular column structure with a semicircular cross-section. The radius of the outer wall of the first sleeve member 2 is smaller than the radius of the inner wall of the second sleeve member 3. By setting radii of different sizes, the staggered arrangement between the first sleeve member 2 and the second sleeve member 3 is achieved, and the two first sleeve members 2 and the second sleeve member 3 together form an enclosed space of a columnar structure. Correspondingly, the enclosed space in the present application can also be composed of three, four, etc. sleeve members, and the present application does not impose any restrictions on this.
[0030] Correspondingly, the slide groove 13 adopts an annular structure, and the slide groove 13 is coaxially arranged with the through hole 4, so that the second sleeve member 3 can rotate along the slide groove 13 with the center of the through hole 4 as the center of the circle. If the first sleeve member 2 and the second sleeve member 3 are set to form an enclosed space, the rotation angle of the second sleeve member 3 is 0°, then when the rotation angle of the second sleeve member 3 is 180°, the inner wall of the second sleeve member 3 and the outer wall of the first sleeve member 2 form a corresponding overlap, thereby forming a semi-enclosed space. When the rotation angle of the second sleeve member 3 is 360°, the first sleeve member 2 and the second sleeve member 3 form an enclosed space again.
[0031] In order to further improve the ease of use of the device of the present application, the protective device also includes a remote controller 5. Servo rollers 6 are installed at the front and rear ends of the side walls where the second sleeve member 3 contacts the bottom of the slide groove 13. The servo rollers 6 are electrically connected to the remote controller 5, and the rotation and rotation direction of the servo rollers 6 can be directly controlled by the remote controller 5.
[0032] In order to adapt to photovoltaic foundations of different heights, refer to Figure 1 In the present application, the first sleeve member 2 specifically includes: a first lower sleeve member 21, and a first upper sleeve member 22 slidably sleeved with the inner wall of the first lower sleeve member 21; the second sleeve member 3 specifically includes: a second lower sleeve member 31, and a second upper sleeve member 32 slidably sleeved with the inner wall of the second lower sleeve member 31.
[0033] Among them, the front and rear ends of the inner side walls of the first lower cylinder member 21 are both provided with driving gears 7, and the front and rear end side walls of the first upper cylinder member 22 are both provided with rack parts, and the rack parts of the first upper cylinder member 22 are respectively meshed with the driving gear 7 of the first lower cylinder member 21 in a one-to-one manner, and the first upper cylinder member 22 is clamped by the driving gears 7 at both ends of the first lower cylinder member 21; the front and rear ends of the inner side walls of the second lower cylinder member 31 are both provided with driving gears 7, and the front and rear end side walls of the second upper cylinder member 32 are both provided with rack parts, and the rack parts of the second lower cylinder member 31 are respectively meshed with the driving gear 7 of the second lower cylinder member 31 in a one-to-one manner, and the second upper cylinder member 32 is clamped by the rack parts at both ends of the second lower cylinder member 31; and on the basis of remote control through the remote controller 5, all the driving gears 7 are electrically connected to the remote controller 5, and the driving gear 7 can be directly controlled to rotate through the remote controller 5, thereby realizing the control of the synchronous rise and fall of the first upper cylinder member 22 and the second upper cylinder member 32, meeting the different requirements of the photovoltaic foundation height.
[0034] Combined with the actual photovoltaic foundation on site, the inner wall radius of the first lower cylinder member 21 is set to 125mm, the inner wall radius of the second lower cylinder member 31 is set to 120mm, the heights of the first sleeve member 2 and the second sleeve member 3 are both set to 300mm, and the sleeve seat 1, the first sleeve member 2 and the second sleeve member 3 are all made of copper and aluminum, and the surface is coated with an aging-resistant coating to meet on-site use requirements.
[0035] Correspondingly, the front and rear ends of the inner side walls of the first lower cylinder member 21 and the front and rear ends of the inner side walls of the second lower cylinder member 31 are both provided with an L-shaped baffle portion 8 which semi-encloses the driving gear 7. The L-shaped baffle portion 8, on the one hand, protects the driving gear 7 and the corresponding rack portion to avoid erosion by external wind and sand; secondly, the L-shaped baffle portion 8 can form an abutment against the inner side wall of the first upper cylinder member 22 or the second upper cylinder member 32, limit the position of the first upper cylinder member 22 or the second upper cylinder member 32, and improve the firmness of the connection between the first upper cylinder member 22 and the second upper cylinder member 32 and the first lower cylinder member 21 and the second lower cylinder member 31, respectively, one by one.
[0036] Specifically, in order to improve the convenience of the device of the present application during use, a sensor 12 facing the enclosed space is installed on the inner wall of the first upper cylinder 22, and the sensor 12 is electrically connected to the remote controller 5. The installation position of the sensor 12 is the position where the sensor 12 performs detection. When the wind and sand inside the protective device accumulates to the installation position of the sensor 12, the sensor 12 issues an early warning to the remote controller 5. At the same time, a predetermined program can also be set to allow the sensor 12 to autonomously control the servo roller 6 on the second lower cylinder 31.
[0037] The protective device also includes an air pump 9 and an air duct 10 electrically connected to the remote controller 5. The air duct 10 is installed on the inner wall of the first upper cylinder 22. The air duct 10 can perform synchronous lifting and lowering movements with the first upper cylinder 22, and one end of the air duct 10 extends vertically downward to the bottom of the first upper cylinder 22, and the other end is connected to the output end of the air pump 9. When the remote controller 5 is used to control the air pump 9 to start, the gas will flow out from the other end of the air duct 10 and blow into the surrounding space. When the position of the second sleeve member 3 changes, the wind and sand blown by the air duct 10 will be blown from the semi-enclosed space to the outside world, thereby clearing the wind and sand.
[0038] In the face of the foundation on which the equipment has been installed on the photovoltaic basis, the sleeve 1 specifically includes two semicircular ring plates that cooperate with each other. Through assembly, the process of disassembling the photovoltaic equipment is eliminated. Combined with the actual situation on site, the practicality of the device of this application is met, and a number of positioning holes are opened on the semicircular ring plates. The nail rod 11 is slidably sleeved in the positioning holes. The sleeve 1 is fixed to the site through the nail rod 11. Combined with the on-site conditions in the desert, the nail rod 11 uses a length of 200 mm to meet the needs of being inserted into the desert for fixation.
[0039] The device protects photovoltaic foundation concrete from wind and sand, can effectively reduce erosion damage to photovoltaic foundation concrete, and increase the service life of the photovoltaic foundation. The infrared sensor 12 can automatically monitor the sand accumulated in the protective device, which is convenient for timely cleaning and maintenance.
[0040] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
