Rainwater collecting device for soilless culture

Abstract

The invention relates to a rainwater collecting device for soilless culture. An opening of a water inlet barrel is downwards, the upper end of the water inlet barrel is provided with a water inlet, the water inlet is provided with a flow guide assembly located at the upper end of the water inlet barrel, a magnetic filter screen is arranged at the position of the opening of the water inlet barrel,the lower end of the magnetic filter screen is provided with a water inlet pipe, and the middle portion of the water inlet pipe is provided with a pelelith layer; the lower end of the water inlet pipeis communicated with a purification barrel; a plurality of accommodating holes for accommodating activated carbon cotton are formed in the purification barrel; a supporting frame is arranged below the purification barrel and provided with a bearing plate capable of rotating around a rotating shaft; the lower end of the left side of the bearing plate is connected with the supporting frame througha spring, and the upper end of the right side of the bearing plate is connected with the purification barrel through a spring; the bearing plate is provided with a bearing block and a water collectingframe which are located on the two sides of the rotating shaft, and the water collecting frame is located under the activated carbon cotton. The upper end of one side of the water collecting frame isprovided with a notch, and a water collecting tank is disposed on one side of the notch. The rainwater collecting device can automatically collect rainwater, the flow guide assembly can be automatically adjusted according to the quantity of the rainwater, and the purity of the collected rainwater is high.

Description

technical field [0001] The invention relates to a rainwater collection device, in particular to a rainwater collection device for soilless cultivation. Background technique [0002] Soilless cultivation is a new cultivation method, which is also called nutrient solution cultivation and hydroponic cultivation. It does not use natural soil, but uses nutrient solution containing essential elements for plant growth and development to provide nutrition, so that plants can complete the whole process normally. Cultivation techniques for the life cycle. It greatly expands the space for agricultural production, enabling crops to be produced without relying on soil, and has broad development prospects. [0003] Soilless cultivation needs to use a large amount of culture fluid to cultivate plants during the cultivation process, but it also needs to spray water on the plants during the cultivation process. Now some water sources are mostly sprayed with farmland water, but such water so...

Problems solved by technology

[0003] Soilless cultivation needs to use a large amount of culture fluid to cultivate plants during the cultivation process, but it also needs to spray water on the plants during the cultivation process. Now some water sources are mostly sprayed with farmland water, but such water sources contain more impurities. , and rainwater is very useful for soilless cultivation, but the rainwater contains more impurities in the early stage, how to filter the rainwater in the early stage, and how to collect rainwater has become a problem that needs to be solved in the field of soilless cultivation
