Description
Technical Field
[0001] This utility model relates to the technical field of rainwater harvesting devices, specifically a rainwater harvesting, filtering and water storage component for greenhouses. Background Technology
[0002] With the rapid development of the economy, greenhouses have become widely used. The technology of using greenhouses for crop cultivation has become increasingly sophisticated, which is of great significance for improving people's living standards and increasing farmers' income. Greenhouse cultivation not only extends the growth cycle of crops and increases yield, but also effectively avoids the impact of severe weather on crops, ensuring a stable supply of agricultural products. Water is crucial for crop growth in greenhouse cultivation, making rainwater harvesting and irrigation particularly important. This method not only saves water resources and reduces production costs, but also reduces dependence on groundwater, contributing to environmental protection. Therefore, developing effective rainwater harvesting systems is of great significance.
[0003] Patent CN219175365U discloses an environmentally friendly greenhouse rainwater harvesting device, belonging to the technical field of rainwater harvesting devices. It includes a greenhouse and a water storage tank. The greenhouse has a fixed roof with a continuous sloping structure. The water storage tank is fixedly installed on the ground, and a lid is hinged to the top of the tank. A rain-collecting baffle adapted to the roof is fixedly installed on the side wall of the greenhouse near the water storage tank. A water-collecting assembly matching the rain-collecting baffle and the water storage tank is fixedly installed on the side wall of the greenhouse. A filter plate is fixedly installed inside the water storage tank. A rotating shaft is rotatably installed on the inner side wall of the water storage tank below the filter plate. A filter stirring assembly is fixedly installed on the shaft inside the water storage tank. A water supply pipe is fixedly inserted through the side wall of the greenhouse. This application effectively utilizes rainwater resources and can also purify rainwater, improving its practicality.
[0004] The existing technology described above intercepts rainwater sliding down the roof through rainwater collection baffles, which then collect it through drain pipes to storage pipes, and finally flow into a water tank through delivery pipes. However, rooftops often accumulate debris such as twigs and leaves, which can easily enter the rainwater collection baffles during rain, causing blockages in the drain pipes, storage pipes, or delivery pipes, thus affecting the normal collection of rainwater. Worse still, once the storage or delivery pipes are blocked, maintenance is very difficult, increasing subsequent maintenance costs. Therefore, we propose a greenhouse rainwater collection, filtration, and storage component. Utility Model Content
