Description

Method for manufacturing portable penetrating rain measurement device

Technical field

The invention relates to the field of forest hydrology, and in particular to a method for manufacturing a portable penetrating rain measuring device.

Background technique

Water is an important substance in the material cycle of forest ecosystems. It also participates in the regulation of forest ecosystems as the main carrier of system material and energy cycles and forest ecological and hydrological processes. From the perspective of water balance, different plant species and their forest stands composed of certain spatial structures have different distribution characteristics of atmospheric precipitation. Therefore, correct observation and analysis of forest distribution patterns of rainfall is of great significance to the analysis and understanding of the role of forest preparation in regulating and distributing water, as well as the resulting spatial patterns and processes. Penetrating rain refers to the rainfall outside the forest (also known as the total forest precipitation) after deducting the canopy interception and trunk runoff. It is an important part of forest precipitation redistribution. The water conservation efficiency of the forest depends to a large extent. Therefore, accurately measuring forest penetration rainfall is of great significance to the study of water balance in forest ecosystems.

However, the current collection and measurement of penetrating rain in the forest canopy mainly consists of a series of other devices such as collection troughs and collection boxes. These devices have the following problems: 1. The height cannot be adjusted flexibly. When the canopy is high, part of the rainwater will splash away when it falls to the collection device; 2. The collection device is easily blocked by litter and other debris in the forest; 3. , The volume of the collection device is small, and there is a risk of rainwater overflowing when the rainfall is heavy.

The specific steps are:

1. Make the filter screen, rainwater trough, water collecting funnel, drainage pipe, buttress, lifting bracket 6 and elbow 8.

2. Set the filters at both ends of the rain collecting trough. The rain collecting trough is placed on the piers. A water outlet hole is opened at the bottom of one end of the rain collecting trough. The water collecting funnel is placed directly below the water outlet hole and connected with the rain collecting trough. The inside of the tank is connected, and the lower end of the water collection funnel is connected to the drainage pipe through an elbow.

3. Set a baffle on the top of the rain collecting trough to avoid partial splash loss when penetrating rain falls into the rain collecting trough when the canopy is high, making rainwater collection more complete; Directly above the funnel; the cross section of the rainwater trough is semicircular.

4. Set a buckle device in the middle of the outside of the buttress to realize the combination of components and facilitate installation and disassembly; the upper part is set into a concave shape with the same size as the rainwater trough, so that the buttress can just accommodate the rainwater trough; there is a reserve in the middle The installation space for the water collecting funnel, elbow and drainage pipe is convenient for disassembly and cleaning of the water collecting funnel, elbow and drainage pipe; the lower part is set in an arch shape to save material; the four edges are hollow inside, leaving space for energy The space to accommodate the lifting bracket is convenient for the lifting bracket. There are screw holes at the four corners of the bottom and matching bolts to fix the lifting bracket. You can use the screw holes and matching bolts to adjust the height of the lifting bracket. The lifting and lowering of the buttresses makes the collection of penetrating rain more complete;

5. Set the bottom of the lifting bracket into a cone, which is conducive to inserting it into the soil to a certain depth to achieve stability of the entire device.

6. Set the filter into a twice-folded shape, and install a lifting handle at the fold to facilitate the removal and cleaning of the filter; the two folded ends of the filter are semicircular, with a diameter equal to the inner diameter of the cross section of the rainwater trough. The semicircles are consistent.

Compared with the prior art, the present invention has the following characteristics:

1). Flexible disassembly and assembly, easy to carry, transport and clean.

2) It is easy and fast to operate, saves time and effort, provides convenience for those engaged in field work, and improves work efficiency.

3) The rain collecting tank has a large capacity, which avoids the risk of rainwater overflowing the collection container when the rainfall is heavy.

4) It is equipped with a filter that can effectively separate debris and penetrating rain, avoid clogging the entire system with litter in the forest, and ensure the quality of collected penetrating rain. At the same time, the filter is easy to disassemble and clean.

5) The rain collecting trough has a large rain receiving area and a baffle, so that when the penetrating rain falls into the rain collecting trough, there will be no splash loss, and it is far away from the ground and will not be disturbed by snakes, rats, insects, ants and other animals. Therefore, the measurement accuracy is higher.

6) There is a screw hole on the lifting bracket for fixing the lifting bracket through bolts. The height can be flexibly adjusted according to the actual situation of the forest sample plot, which improves the reliability and representativeness of the measurement.
