Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rainwater collection, in particular to a rainwater collection device used for desert grassland control tests. Background Art
[0002] Desert steppe is the most xerophytic type of grassland. The dominant species are xerophytic clumps of small grasses, often mixed with a large number of xerophytic small semi-shrubs, forming a stable dominant layer in the community. Desert steppe is a natural zone, mainly formed by the influence of the natural environment.
[0003] Chinese patent announcement No. CN215715718U discloses a rainwater collection device for controlling experiments in desert grasslands. When hydraulic cylinders 1 and 2 move, they respectively control the up and down movement of connecting plates 1 and 2. The arc-shaped slider slides along the inner wall of the arc-shaped slide groove. Since the arc-shaped slider is limited by connecting plate 1 and can only move up and down, the arc-shaped slider will drive the rotating ring to rotate when sliding along the inner wall of the arc-shaped slide groove. At this time, the rotating ring moves up and down accordingly, and as the arc-shaped slider slides on the inner wall of the arc-shaped slide groove, the rotating ring rotates and drives the rubber sleeve fixed at the top to rotate. The rubber sleeve and the rotating ring move upward at the same time and are gradually sleeved on the outside of the drainage plate. At this time, the gap inside the main body is small except for the filter holes of the filter plate, which can effectively reduce the evaporation of water, facilitate storage, and facilitate subsequent rainwater testing. Water can be easily taken through the water valve, which is convenient and quick.
[0004] The above-mentioned collecting device controls the hydraulic cylinder so that the hydraulic cylinder drives the filter plate to rise and fall until it moves to the outer wall of the drainage plate; however, the rainwater collecting device in the above-mentioned application is applicable to desert areas. Therefore, if the filter plate is not sealed, the rainwater will evaporate through the filter holes of the filter plate, making it difficult to subsequently sample the rainwater. Therefore, there are certain limitations. Utility Model Content
