Description

Technical Field

[0001] This invention belongs to the field of desert photovoltaic water distribution and wind regulation technology, specifically relating to a desert photovoltaic water distribution and wind regulation device and method. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] In desert photovoltaic (PV) installations, the supporting piles are all set in the sand, securing the PV panels by burying them at a certain depth. Because the PV panels are tilted at a certain angle relative to the ground, a funnel-shaped channel is formed between the panels and the ground. When wind blows towards the PV panels, especially towards the back of the panels, it's like air being forced into the flared end of the funnel. Higher wind speeds are generated at the front end of the panels (the constricted end of the funnel). Under this airflow, the sand on the ground is blown outwards, creating wind erosion. Over time, this causes the sand level where the piles are buried to drop, weakening the stability of the piles. Therefore, measures need to be taken to prevent this wind erosion.

[0004] To combat desertification, photovoltaic devices are installed in the desert while grass seeds are sown. Under the shading effect of the photovoltaic devices, the grass under the photovoltaic panels grows well. However, the photovoltaic panels also block rainwater to some extent, resulting in the grass growing well at the edges of the photovoltaic panels, but the grass directly under the photovoltaic panels is sparse. Summary of the Invention

[0005] To address the aforementioned problems, this invention proposes a desert photovoltaic water distribution and wind regulation device and method, which can solve the problems of wind erosion and uniform distribution of vegetation and rainwater in desert photovoltaic panels.

[0006] According to some embodiments, the present invention adopts the following technical solution:

[0007] A desert photovoltaic water distribution and wind regulation device includes a water-blocking curved plate, multiple water-distributing straight plates, and supporting components. The water-blocking curved plate has a certain curvature on one side and is located on the lower side of the photovoltaic panel. The curved side of the water-blocking curved plate faces the lower side of the photovoltaic panel.

[0008] Next to the water-blocking bend, at the lower end of the photovoltaic panel, there are multiple water-level straight plates, which are arranged side by side and the height of each water-level straight plate decreases sequentially.

[0009] Each straight water distribution plate has a supporting component at its lower end.

[0010] As an alternative implementation, the height gradient between the various water leveling plates is reduced.

[0011] As an alternative implementation, one side of the water-retaining bend is an arc portion, which is located at the lower front edge of the photovoltaic panel and surrounds the lower edge. This arrangement allows rainwater on the photovoltaic panel to collect at the water-retaining bend, and then be distributed from the bend to the various water-distributing plates.

[0012] As an alternative implementation, each water leveling plate has two support components at its bottom, located on both sides of the water leveling plate. One end of each support component is connected to the bottom of the water leveling plate, and the other end is placed on the ground.

[0013] As an alternative implementation, the supporting component is a cylinder with an internal cavity, and the water-distributing plate has two through holes communicating with the cavity. This allows it to hold a portion of rainwater.

[0014] As an alternative implementation, the other side of the water-blocking bend is a straight water-distributing plate that is smoothly connected to the arc-shaped side.

[0015] As an alternative implementation, a support member is provided at the lower end of the water-blocking bend plate and a support member is provided at the lower end of the photovoltaic panel. At the position where the water-blocking bend plate or / and the water-leveling straight plate interfere with the support member of the photovoltaic panel, a notch is provided to accommodate the support member of the photovoltaic panel.

[0016] As an alternative implementation, the height spacing between each water leveling plate is adjustable.

[0017] As an alternative implementation, the water leveling plate has a certain tilt angle, and the size and tilt angle of the water leveling plate are preset.

[0018] The working method of the above-mentioned device includes the following steps:

[0019] The photovoltaic panels are tilted so that when it rains, rainwater flows down the photovoltaic panels. Under the action of the water-blocking bend, the direction of the water flow is changed and the water flowing down is directly received by the top water-distributing plate. The water-distributing plate guides the water to the next water-distributing plate. The rainwater flows to all four sides on the water-distributing plate and falls to the ground from the edge of the water-distributing plate. Each layer of water-distributing plate has the same function.

[0020] With the action of all the water-distributing straight plates, rainwater can be evenly distributed under the photovoltaic panels;

[0021] The wind blowing from the back of the photovoltaic panel flows out through the channels between the layers of water-level straight plates. Guided by the water-level straight plates, the airflow flows out in a direction parallel or nearly parallel to the ground, thus avoiding wind erosion of the ground.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] This invention, through the structure and arrangement of the water-blocking curved plate and the water-distributing straight plate, ensures that rainwater is evenly distributed under the photovoltaic panel, solving the problem of uniform rainwater distribution required for plant growth in desert areas and helping to improve the efficiency of vegetation growth.

[0024] This invention creates a funnel-shaped space between the water leveling plate and the photovoltaic panel, guiding airflow onto the water leveling plate, reducing the amount of wind flowing across the ground, effectively reducing the erosive effect of airflow on the ground and photovoltaic panel, improving the service life of the photovoltaic panel, and reducing maintenance costs.

[0025] This invention can reduce the wind pressure effect of particulate matter on photovoltaic panels, extend their lifespan, and lower maintenance and replacement costs. The size, height, tilt, and materials of the water leveling plate can be adjusted according to site conditions and economic factors to meet the requirements of different regions and needs, demonstrating wide adaptability and flexibility.

[0035] Example 1

[0036] A desert photovoltaic water distribution and wind regulation device includes: a photovoltaic panel 1, a water-blocking bend plate 2, a ground 3, a support component 4, a water-distributing straight plate 5, and a photovoltaic panel support 6. The photovoltaic panel 1 is installed on the photovoltaic panel support 6. The water-distributing straight plate 5 is installed on the support component 4. Each water-distributing straight plate 5 is arranged sequentially below the photovoltaic panel 1. There is a certain height difference between each water-distributing straight plate 5, and the arrangement height of the water-distributing straight plates 5 increases sequentially. The water-blocking bend plate 2 is installed at the upper end of the highest water-distributing straight plate. The photovoltaic panel support 6 and the support component 4 are installed on the ground.

[0037] In this embodiment, the photovoltaic panel 1 is a cuboid, and there is one of them. The photovoltaic panel support 6 is cylindrical, and there are four of them, with two different lengths.

[0038] In this embodiment, there are 4 water leveling plates 5, and they are rectangular in shape.

[0039] In this embodiment, one side of the water-blocking bend 2 is arc-shaped.

[0040] Of course, in other embodiments, the number of the above parameters can be determined or adjusted according to the actual situation on site.

[0041] In some embodiments, there are multiple water leveling plates 5, each water leveling plate 5 (with support) is an independent entity, and the shape and tilt of the water leveling plate 5 are adjustable.

[0042] The specific quantity can be determined according to the needs of the site. Multiple straight water-distributing plates (with supports) are independent and combined together in a fixed spatial position to form the equipment of this invention. The front end of the water-blocking bend is arc-shaped and is set at the lower front edge of the photovoltaic panel, surrounding the lower edge line. The water-blocking bend with support is also an independent unit.

[0043] like Figure 1As shown, on rainy days, rainwater flows down the photovoltaic panel 1. Under the action of the water-blocking bend 2, the flowing water is directly received by the topmost water-distributing plate 5. The water-distributing plate 5 guides the water to the next layer of water-distributing plates. The rainwater can flow to all four sides of the water-distributing plate 5 and fall to the ground 3 from the four sides. Each layer of water-distributing plates 5 below has the same function. With the action of all the water-distributing plates 5, the water can be evenly distributed under the photovoltaic panel. The size, height, inclination, and material of the water-distributing plates 5 can be set according to local conditions and economic factors. Wind blowing from the back of the photovoltaic panel will flow out through the channels between the layers of water-distributing plates 5. Under the guidance of the water-distributing plates 5, the airflow flows out in a direction parallel to the ground, avoiding wind erosion of the ground.

[0044] Meanwhile, all the water distribution plates 5 are combined with the photovoltaic panel 1 to form a funnel-shaped space, guiding the airflow onto the water distribution plates 5, reducing the amount of wind flowing across the ground and minimizing wind erosion. Because there are gaps between the water distribution plates 5, the airflow can be channeled in time, preventing excessive wind pressure on the photovoltaic panel 1.

[0045] like Figure 2 As shown, a notch 7 is provided at the position where the water-blocking bend 2 or / and the water-level straight plate 5 interferes with the supporting component of the photovoltaic panel 1, so as to accommodate the supporting component of the photovoltaic panel.

[0046] In some other embodiments, the water leveling plate 5 can be set at an angle, that is, at a certain angle to the ground.

[0047] 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 by those skilled in the art without creative effort within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
