Description

Technical Field

[0001] The invention relates to the technical field of forestry research, and in particular to a forest rain interception device. Background Art

[0002] Throughfall is the amount of rainfall that reaches the ground after passing through the forest canopy. Accurately measuring forest canopy throughfall is of great significance for the study of ecosystem water balance.

[0003] Traditionally, forest canopy penetration rainfall is mostly measured by randomly placing standard rain gauges. Due to the complex forest structure and the small precipitation collection area of ​​standard rain gauges, the measured results often deviate greatly from the actual results. At the same time, traditional penetration rainfall collection tubes often require manual observation, which has large errors and is time-consuming and labor-intensive when observing continuous or multi-period rainfall. Traditional collection devices composed of brackets and plastic sheets can collect rainwater over a large area, but due to the complex internal environment of deep forests, the plastic sheet is fragile and easily damaged without effective protection, which affects the rainwater collection results.

[0004] In addition, since the texture of plastic sheeting is not tough enough, it is very easy to age after being exposed to wind, sun and rain, and the plastic sheeting needs to be replaced from time to time. Since the time of damage of plastic sheeting is uncertain, it is necessary to carry plastic sheeting and installation tools every time rainwater is collected or rain interception devices are repaired, which is extremely inconvenient to carry in the forest.

[0005] Chinese patent application "CN201620634090.4 A natural grassland rain reduction test device" mentions a rainwater interception and collection device consisting of a support frame, a rain interception trough, a water receiving pipe and a water storage tank. The support frame is a trapezoidal support frame with a high rear end and a low front end. A number of angle steel support beams with adjustable spacing are welded on the support frame at equal intervals, and a plurality of V-shaped brackets are welded on each angle steel support beam. A plurality of rain interception troughs are longitudinally fixed on the support frame by the V-shaped brackets. Its structure and scheme solve the problem of rain interception and collection, but its rain interception trough is composed of a fixed plate, which is inconvenient to carry and replace and install, and rainwater is easily splashed out of the rain interception trough when it contacts the solid plate. In addition, there is a lack of a shielding frame to prevent falling objects or interference from external factors, which can easily cause blockage and damage to the collection device, thereby affecting the collection effect of rain interception. Summary of the invention

[0012] Furthermore, the fixing buckle includes a lower base fixed to the bottom surface of the support rod, and an upper buckle plate inserted on the lower base, an insertion rod is arranged below the upper buckle plate, and an upper and lower positioning rings are arranged on the insertion rod. A socket matching the insertion rod is opened on the lower base, and the inside of the socket can be engaged with the positioning ring. The upper buckle plate is positioned up and down by the cooperation between the insertion rod and the socket.

[0013] Furthermore, the arc hoop comprises two concentrically arranged arc rings and fixed sections arranged on both sides of the arc rings, a gap is left between the two arc rings and the fixed sections to allow the plastic sheet to pass through, and the cross section of the arc ring is circular.
