Description

Technical Field

[0001] The invention relates to the technical field of rainwater collection, and more particularly to a karst ecological protection type solar energy and water storage device. Background Art

[0002] In the karst area, located in the subtropical monsoon climate zone, there is abundant rainfall. However, due to the high permeability of lime soil and the developed karst fissures, the surface water resources are seriously lost to the karst pores. A large amount of water resources are transported out through cracks, karst holes, underground rivers and surface karst zones, resulting in a "no water available" situation. It is precisely because of the high permeability of lime soil above the surface that rainwater quickly penetrates into the rock-soil interface when it falls, and the high karst fissures and karst holes below the surface cause rainwater to quickly enter the underground river. Traditional water collection methods are inefficient, making it difficult to utilize natural water resources in many ways, and the impact on the ecological environment is not considered during the construction period.

[0003] The abundant sunlight resources in the karst region are conducive to solar power generation. However, the karst landform has unique topographical features, which will bring certain challenges to the layout and construction of large-scale solar power generation facilities. For the laying of a single solar panel, the exposed rocks in the karst region can easily provide support points for fixed equipment, and the construction of a single solar panel is not economically efficient.

[0004] In the utilization of karst water resources, more and more researchers have proposed technologies, which to some extent solve the problem of water collection and storage in karst areas, but all of them have obvious shortcomings: 1. When considering water collection and storage, they do not consider collecting water from the source, but consider collecting water after it enters the soil or rock cracks. 2. Some technologies only consider the requirements for water storage technology, but ignore the fragile ecological environment in the karst area. 3. When considering solar energy water storage, the impact of weather is not considered. Some even proposed surface interception and water storage without understanding that the soil infiltration in the karst area is fast and surface runoff requires heavy rainfall.

[0005] Therefore, it is an urgent problem for technicians in this field to develop a karst ecological protection type solar energy and water storage device that can store water and utilize light. Summary of the invention

[0006] In view of this, the present invention provides a karst ecological protection type solar energy and water storage device which can store water and utilize light.

[0016] Preferably, the surface filter layer is a plant belt filter layer, and water enters the ditch after being filtered through the plant belt filter layer. The plant belt filter layer can filter large impurities such as fallen leaves, mud and sand in the water flow.

[0017] Preferably, a water collecting baffle is arranged vertically on the downhill side of the ditch, and a waterproof cushion is arranged at the bottom of the ditch. The water collecting baffle and the waterproof cushion can conveniently store water temporarily and prevent water from seeping into the ground.

[0018] Preferably, two filter layers are laid in the ditch, and the two filter layers can filter water.

[0019] Preferably, the upper filter layer is a mixed filter layer of pebbles or gravel and coarse sand; the lower filter layer is a coarse stone sand biochar filter layer.

[0020] Preferably, one end of the drainage pipe connected to the ditch is connected to a flexible concealed pipe, the flexible concealed pipe is located inside the ditch, and the flexible concealed pipe is provided with a seepage hole, the seepage hole is funnel-shaped.

[0022] Preferably, the water reservoir is provided with a water outlet and a pressure drain pipe, and the water outlet and the pressure drain pipe are respectively located at the upper part and the lower part of the side wall of the water reservoir. The pressure drain pipe is used to discharge the sediment settled in the water reservoir, and the water outlet can also be used as a spillway.

[0027] (4) Installing solar panels on the hillside is equivalent to increasing the vegetation coverage of the slope, so that the function of the plant protection belt to prevent rain splashing is replaced by solar panels, which is conducive to maintaining karst soil and water conservation, helping to reduce soil erosion, and thus protecting the fragile ecological environment of the karst area.

[0028] (5) The device of the present invention has a simple structure and is easy to install and maintain in karst areas. It also has a compact structure and can achieve efficient water collection and energy utilization in a limited space. It is very suitable for karst areas with complex terrain and limited space.
