[0002] The provinces that are mainly involved in the farmland on the dams in my country include Hebei Province, Inner Mongolia Autonomous Region, Shanxi Province, etc. The terrain is high and the surface undulations are not big. The altitude is between 1400 and 1800 meters. The overall terrain is high in the south and low in the north. According to the structural unit and landform type, it can be divided into the southern dam edge zone (the middle and low mountains running east-west), the central wavy plateau (relatively flat and open terrain), and the northern Yinshan dome fold zone (the low mountain and hilly area covered with residual slope deposits and wind deposits). The soil arable layer is shallow and is in a state of water shortage all year round. The active soil layer is shallow and loose, and the farmland is dry and exposed, which is very easy to be eroded and desertified by wind.

[0003] Agriculture occupies an important position in the economy of Zhangjiakou Bashang area, mainly planting oats, wheat, vegetables, potatoes, sesame, etc. However, water scarcity has always been one of the key factors restricting the development of agriculture in the region. Limited water resources cannot meet the needs of the entire process of crop growth, resulting in insufficient irrigation of farmland, unstable crop yields, and affected farmers' income. Traditional irrigation methods mainly rely on groundwater extraction, but long-term over-exploitation of groundwater has led to a decline in groundwater levels, triggering a series of ecological and environmental problems, such as land desertification and ground subsidence, further threatening the sustainability of agricultural production. At the same time, the quality of groundwater may also be affected by geological conditions and human activities. It contains high salt or other minerals, which is not conducive to the growth of crops. Long-term use may lead to soil salinization and reduce soil fertility.

They are used to explain the present invention together with the embodiments of the present invention and do not constitute a limitation of the present invention.

Implementation

[0017] The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. The embodiments of the present invention will be described below in conjunction with the accompanying drawings. Example

[0018] The embodiment of the present invention provides a solar panel rain collection technology suitable for farmland in the dam area, such as Figure 1 and Figure 2 As shown, it includes a solar power generation device and a rainwater collection device. The solar power generation device includes a solar cell array, a connector and an inverter. The solar cell array converts solar energy into electrical energy. The connector is used to connect the solar cell array with the inverter. The inverter converts direct current into alternating current to provide power support for the rainwater collection device. The rainwater collection device consists of a reservoir, a filter tank and a water pump. The reservoir is used to collect rainwater, the filter tank filters and purifies the rainwater to remove impurities and pollutants, and the water pump is used to transport water in the reservoir to farmland for irrigation.

[0019] like Figure 2 As shown, a first water pump is provided between the water reservoir and the filter tank, the first water pump is connected to the water reservoir through a water pumping pipe, the first water pump and the filter tank are connected through a water inlet pipe, a first valve is provided on the water inlet pipe, the water outlet of the filter tank is connected to the second water pump, the pipe mouth of the second water pump is connected to a water hose, and the clean water filtered by the filter tank is transported to the farmland for irrigation through the water hose under the action of the second water pump.

[0020] like Figure 1As shown in the figure, a remote monitoring and data analysis platform is established to transmit the operating data of solar power generation devices, rainwater collection devices, and irrigation systems to the cloud server in real time through wireless communication modules (such as 4G / 5G networks). Farmers and agricultural managers can remotely view equipment status, water level information, power generation, irrigation records and other data through mobile phone APP or computer web pages, and perform remote control operations such as starting or stopping water pumps. At the same time, the platform uses big data analysis technology to deeply mine the collected data, provide farmers with irrigation decision-making suggestions, equipment maintenance reminders, meteorological disaster warnings and other services, and realize intelligent management of agricultural production.

[0021] like Figure 2 As shown, the bottom of the filter tank is connected to the fertilizer tank, a second valve is provided between the fertilizer tank and the filter tank, the fertilizer tank is provided with a stirring device, and the stirring device is connected to the controller. During the fertilization process, the controller controls the stirring device to work so that the fertilizer is evenly mixed in the rainwater.

[0022] To further optimize the solution, Figure 2 The middle reservoir adopts a cylindrical design. This shape can obtain a larger volume with the same amount of materials and has good structural stability. The wall of the reservoir is cast by reinforced concrete with a thickness of 20 cm. Waterproof concrete is used inside to ensure good waterproof performance. The bottom of the pool is also cast by reinforced concrete with a thickness of 30 cm. After the concrete pouring is completed, the inner wall and the bottom of the reservoir are first polished to make the surface smooth and smooth, and then a layer of waterproof coating with a thickness of 2 mm, such as polymer cement waterproof coating, is applied to form a waterproof layer. After the waterproof layer is cured, a layer of plastic film with a thickness of 0.5 mm is laid to further enhance the anti-leakage effect. The plastic film should be laid flat, without wrinkles and damage. The films are connected by hot welding to ensure good sealing. Considering the cold climate conditions in the dam area in winter, a 10 cm thick polystyrene foam board insulation layer is laid on the outside of the reservoir wall and under the bottom of the pool. The insulation layer uses flame-retardant materials and has good thermal insulation performance.

[0023] Specifically, Figure 2 As shown in the figure, the water inlet of the reservoir is located at the top of the reservoir, collecting rainwater flowing down from the hillside. A trash rack is installed at the water inlet. The spacing between the bars of the trash rack is 5 mm, which can effectively block larger debris such as leaves and branches from entering the reservoir, preventing the accumulation of debris from affecting the water inlet and water quality. A simple sedimentation tank is set behind the trash rack. The depth of the sedimentation tank is 30 cm, the length is 1 meter, and the width is the same as the water inlet, so that the rainwater can be initially precipitated before entering the main body of the reservoir. The sediment and other impurities after precipitation can be regularly cleaned through the mud discharge pipe at the bottom of the sedimentation tank.

[0024] To further optimize the plan, the reservoir is set up in a low-lying area, which can utilize the natural terrain and allow rainwater to naturally gather in the reservoir under the action of gravity. No additional power equipment is needed for collection, which reduces energy consumption. The solar power generation device is set up in a high and unobstructed place. Because the high and unobstructed position can receive sunlight earlier and lose sunlight later at sunset, the effective working time of the solar power generation device is extended, the power generation is increased, and more sufficient power support is provided for the entire rain collection technology system.

[0025] To further optimize the plan, a special wind and sand protection cover is designed for the solar power generation device. The protection cover is made of high-strength, corrosion-resistant transparent materials (such as polycarbonate panels), which can not only resist the invasion of wind and sand, but also does not affect the lighting of the solar cell array. The shape of the protection cover is streamlined according to the equipment layout to reduce the impact of wind and sand on it. At the same time, a deep-buried wind and sand fixing device is installed at the bottom of the equipment, which consists of a ground anchor and a connecting bracket made of high-strength steel to firmly fix the equipment on the ground, ensure the stability of the equipment in strong winds in the dam area, and prevent equipment damage and displacement.

[0026] The working process of the invention is as follows: when it rains, rainwater naturally flows into the reservoir for collection. In the irrigation season, according to the water demand of the crops in the farmland, the first pump and the second pump are turned on to transport the filtered rainwater to the farmland for irrigation through the water belt. If fertilization is required, the second valve between the fertilizer tank and the filter tank can be opened at the same time to mix the fertilizer with rainwater for irrigation; regularly check and maintain the solar power generation device, rainwater collection device and irrigation equipment to ensure their normal operation. Clean the dust on the surface of the solar cell array, check whether the pipes and valves are leaking, and maintain the normal working condition of the water pump and other equipment. Example

[0027] District layout Taking the Bashang farmland in Zhangjiakou City as an example, the average annual rainfall in the area is 300-400 mm, and the natural rainfall is not enough to meet the local crop growth needs.

[0028] (II) Investment budget The budget required for laying according to the device of the present invention is as follows: Reinforced concrete: The wall thickness of the reservoir is 20 cm, and the bottom thickness is 30 cm. Assuming the diameter of the reservoir is 6 meters (according to the cylindrical volume formula, when the height is about 3.5 meters, the volume is close to 100 cubic meters), the volume of the wall is about 13.19 cubic meters, and the volume of the bottom is about 8.47 cubic meters. The cost of reinforced concrete per cubic meter is about 500 yuan (including steel bars, cement, sand and gravel and other materials and mixing and transportation costs), so the cost of reinforced concrete materials is about (13.19 + 8.48) * 500 = 10,835 yuan.

[0029] Waterproof coating: The inner wall and bottom area of ​​the reservoir is about 80.11 square meters. The cost of waterproof coating is about 30 yuan per square meter, so the cost of waterproof coating is about 80.11*30=2403.3 yuan.

[0030] Plastic film: The area is the same as the inner wall and the bottom of the pool, about 80.11 square meters. The cost of plastic film per square meter is about 10 yuan, so the cost of plastic film is about 80.11*10=801.1 yuan.

[0031] Polystyrene foam board insulation layer: The volume of the insulation layer on the outside of the pool wall and under the pool bottom is about 15.08 cubic meters. The cost of each cubic meter of polystyrene foam board is about 300 yuan, so the cost of the insulation layer material is about 15.08*300=4524 yuan.

[0032] Construction cost: including excavation, formwork construction, steel bar binding, waterproofing construction, insulation layer laying, etc., the estimated construction cost is about 10,000 yuan.

[0033] The cost of pipes and water hoses is estimated to be 1,000 yuan, two water pumps 3,000 yuan, various valves and trash rack accessories 2,000 yuan, the filter tank includes the tank body, filter medium, etc., the filter tank is made of stainless steel, with a volume of 1 cubic meter and a price of about 5,000 yuan, and the cost of the fertilizer tank is made of plastic, with a volume of 0.5 cubic meters and a price of about 1,500 yuan.

[0034] Solar cell array cost: If a 10-kilowatt double-sided solar panel is selected, the cost per kilowatt is about 4,000 yuan, then the cost of the cell array is about 40,000 yuan.

[0035] Connector and inverter cost: Choose reliable quality connectors and inverters, the price is about 10,000 yuan.

[0036] Anti-wind and sand protection cover: Made of polycarbonate board, with an area of ​​about 50 square meters and a cost of about 300 yuan per square meter, the cost of the protection cover is about 15,000 yuan. Anti-wind and sand fixing device: including ground anchors and connecting brackets, with a cost of about 5,000 yuan.

[0037] Remote monitoring and data analysis platform cost: including hardware equipment (servers, sensors, communication modules, etc.) and software development costs. The rental cost is approximately RMB 5,000 per year.

[0038] In summary, the total cost of a set of invention devices is about 116,363.4 yuan, and the estimated cost is 116,000 yuan.
