A rainwater collection and sprinkler irrigation device for greenhouses

Abstract

The invention discloses a rainwater collection and sprinkler irrigation device for greenhouses, which combines the scaffolding to increase the range of rainwater collection, and changes the two modes of water collection and anti-water accumulation by changing the filling and pumping of the airbag. , characterized in that the scaffold is provided with a plurality of installation grooves, the plurality of installation grooves are distributed in a rectangular array, the installation groove is built with an air bag, the air bag is fixedly connected to the scaffold, and the center position of the air bag A water hole is provided, and a sprayer is placed at the middle of the bottom of the air bag, and the sprayer communicates with the water hole correspondingly, a solenoid valve is arranged on the passage in the sprayer, and an increaser is arranged on the passage in the sprayer. The pressure pump, the booster pump is located below the solenoid valve, the booster pump is connected to the internal channel of the sprayer, the spray head is placed at the bottom of the sprayer, and a circle of protective bosses is placed on the edge of the installation groove. A plurality of drainage grooves are arranged on the protective boss, and the groove edge of the installation groove is an inclined plane.

Description

technical field [0001] The invention relates to a rainwater collection and sprinkler irrigation device used in a greenhouse, relates to a rainwater collection and utilization sprinkler irrigation device used in a greenhouse, and belongs to the field of agricultural planting. In particular, it relates to a rainwater collection and sprinkling irrigation device which can improve the range of rainwater collection in combination with a scaffold, and can change two modes of water collection and anti-water accumulation by changing the inflation and pumping of airbags. Background technique [0002] Greenhouse planting can greatly reduce the impact of natural meteorological disasters on crops, making planting and production basically free from the constraints of natural conditions. In arid areas, due to the lack of water resources as a whole, the use of rainwater is extremely valued by people, and the existing ones can be carried out. Most of the greenhouses for rainwater recycling u...

[0002] Greenhouse planting can greatly reduce the impact of natural meteorological disasters on crops, making planting and production basically free from the constraints of natural conditions. In arid areas, due to the lack of water resources as a whole, the use of rainwater is extremely valued by people, and the existing ones can be carried out. Most of the greenhouses for rainwater recycling use the drainage pipes to collect the rainwater on the greenhouses for reuse. However, due to the small collection area of ​​the drainage pipes and the low utilization rate of rainwater, and the elastic and flexible structure of the greenhouse surface, it makes In the process of collecting rainwater, part of the rainwater will accumulate on the surface of the greenhouse, resulting in a sunken puddle, which will affect the collection of rainwater and increase the pressure load of the greenhouse

[0003] Notification number CN209105769U discloses a greenhouse for vegetable planting with recyclable rainwater, comprising a greenhouse body, characterized in that a reservoir is arranged on the top of the greenhouse body, and the bottom periphery of the reservoir is connected to the upper end of the first pipeline. communicated, the first pipeline extends down to the body of the second pipeline along the side of the greenhouse body, the first pipeline communicates with the second pipeline, and the second pipeline is inclined and extends along the side of the greenhouse body to the water storage pool, the rainwater in the storage tank flows into the water storage barrel through the first pipeline and the second pipeline, and the third pipeline is arranged in the greenhouse, and the third pipeline is connected with the water pump outside the greenhouse, and the water pump is connected with the water storage tank. The barrels are connected by water pipes, the third pipe includes a first section and a second section, the first section extends upwards along the inner wall of the greenhouse to above the greenhouse body, the second section communicates with the first section and the second section hangs above the greenhouse body , the first section and the second section are equipped with a plurality of nozzles, the nozzles are facing the vegetable planting area and the nozzles are equidistantly arranged, the collection range of the rainwater recovery pipeline in this greenhouse is small, and it is impossible to self-clean the accumulated water on the greenhouse

[0004] Notification number CN209732114U discloses a greenhouse with rainwater recycling function, including a greenhouse body, the inner wall of the greenhouse body is fixedly connected with a support frame, the inner wall of the support frame is fixedly connected with a main pipeline, and the inner wall of the support frame The support column is fixedly connected, the bottom of the main pipeline is fixedly connected with a thermal insulation pad, and the outer wall of the main pipeline is fixedly connected with a branch pipeline. After recovering the rainwater flowing down from a high place, the greenhouse needs to work again to pump the rainwater. The pressurization makes it rise to each spray head on the greenhouse, resulting in a large workload on the pump body, and at the same time, the flexible shed surface of the greenhouse is prone to water accumulation
