Abstract
The utility model discloses a device for collecting and recording quantity of rainwater intercepted by a canopy in the same period. The device comprises a carrier rod support, a carrier rod, a guide pipe, rainwater collection disks and accumulation cylinders. The carrier rod is horizontally arranged through the carrier rod support. Two ends of the carrier rod are vertically provided with one funnel-shaped rainwater collection disk respectively. Constriction openings of the two rainwater collection disks are communicated with a water inlet of one inclined guide pipe respectively. Water outlets of the two guide pipes are positioned in mouths of the accumulation cylinders respectively. One of the two rainwater collection disks is positioned in an area below the canopy, and the other is positioned in an open area out of the canopy, so that quantity of rainwater in the same environment in the same period can be collected in a canopy shielding condition and a non-canopy shielding condition. By comparison of the volume of rainwater in the two accumulation cylinders, an accurate canopy interception rate can be obtained. The device is advantaged in that collection of rainfall values under two rainwater collection conditions in the same period can be achieved, structure is simple, operation is convenient, and measurement precision is high.
Description
Technical field
The utility model belongs to forest ecology monitoring field, specifically, is a kind of measuring equipment of crown interception rainfall.
Background technology
In Forest Cultivation and ecoscape restoration and reconstruction, forest canopy precipitation is very important hydrology phenomenon, is subject to concern and the research of forest hydrology always.According to domestic and international existing achievement in research and data, in the larger forest of canopy density, crown canopy can reach 10～20% to the interception of rainfall, and year interception and rainfall amount, the rainfall intensity of crown canopy are relevant with the rainfall frequency, and total amount can reach annual precipitation 15～45%.On the one hand, this part rainfall will consume in evaporation, reduce greatly the actual rainfall on ground and effectively supplementing of Forest Soil Moisture, be a kind of unhelpful loss of rainwater resource, in the situation that water resource is day by day in short supply, how reducing forest canopy amount needs us conscientiously to study; On the other hand, in some mountain torrents Yi Fa districts and the multiple forest zone of soil erosion, due to the effect of forest canopy, can weaken to a certain extent rainfall intensity, the runoff forming process that slows down rainfall, reduces surface runoff amount, for stagnant flood storage water and reduction rain flood, washes away actively impact of surface soil generation.
To this, in actual scientific research, often need to measure accurately the size of rainfall amount under crown canopy, or calculate the rainfall amount under crown canopy according to crown canopy exterior domain rainfall amount size, measurement process is single, independent separately, cause observation data comparatively rough, cannot accomplish especially the observation same period and the comparison of a rainfall.For the problem of above existence, the present invention proposes a kind of forest canopy rainfall same period acquisition and recording device.
Summary of the invention
For the problems referred to above, the utility model proposes a kind of crown canopy block under condition with the unobstructed condition of spaciousness under simultaneously with the rainfall harvester in border.
The utility model forest canopy rainfall same period acquisition and recording device, is characterized in that: comprise pressure pin support, pressure pin, guiding tube, collection rain dish and collection graduated cylinder.
Described pressure pin arranges by pressure pin support level; Described collection rain dish is two, is funnel-form, is vertically arranged on the two ends of pressure pin; Described guiding tube is two, is all obliquely installed, and the water inlet end of two guiding tubes is communicated with the contraction mouth of two collection rain dishes respectively; Water side lays respectively in a collection graduated cylinder nozzle.
In use, will make in two collection rain dishes one be positioned at crown canopy lower zone, another is positioned at the outside spacious region of crown canopy, realize thus crown canopy block under condition with the unobstructed condition of spaciousness under simultaneously with the rainfall collection in border.The rainwater in the outside spacious region of crown canopy lower zone and crown canopy falls into respectively two collection rain dishes, flows in two collection graduated cylinders respectively through two guiding tubes; Comparison by water yield volume in two collection graduated cylinders, can precisely draw rate of canopy interception.
The utility model has the advantage of:
1, the utility model forest canopy rainfall same period acquisition and recording device, can realize two kinds of collection rain conditions and descend gather the same period of rainfall amount value; Gather rainfall amount value under forest canopy condition, the comparison by water yield volume in two rain gage buckets, draws rate of canopy interception;
2, the utility model forest canopy rainfall same period acquisition and recording device, simple in structure, easy to operate, measuring accuracy is high.

Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
A kind of forest canopy of the utility model rainfall same period acquisition and recording device, comprises pressure pin support 1, pressure pin 2, guiding tube 3, collection rain dish 4 and collection graduated cylinder 5, as shown in Figure 1.
On described pressure pin support 1, pressure pin 2 is installed, by pressure pin support 1, pressure pin 2 is horizontally disposed with.For making pressure pin 2 strong fixs, pressure pin support 1 can adopt n, and n>1, realizes the support to pressure pin 2 jointly.In actual applications, because the length of pressure pin 2 is longer, so pressure pin 2 can adopt end thread between m root connecting rod to connect common assembling formation, m>1.
Described collection rain dish 4 is two, as crown canopy below collection rain dish and the outside collection of crown canopy rain dish, is funnel-form respectively, is vertically arranged on the two ends of pressure pin 2; And the edge of two collection rain dish 4 top extension mouths is all designed to outer otch, has outward-dipping inclined-plane 6, as shown in Figure 2; Make thus two collection rain dishes 4 can collect accurately precipitation raindrop, and then guarantee the primitiveness of data and the simultaneity of rainfall sampling process.
Described guiding tube 3 is two, respectively as crown canopy below rainfall guiding tube and the outside rainfall guiding tube of crown canopy; Two guiding tubes 3 are obliquely installed, and make water inlet end plane of living in higher than water side plane of living in.Wherein, the water inlet end of two guiding tubes 3 is communicated with the contraction mouth of two collection rain dishes 4 respectively; Water side lays respectively in collection graduated cylinder 5 nozzles.Thus, by crown canopy below rainfall guiding tube and the outside rainfall guiding tube of crown canopy, respectively the rainwater that below crown canopy, the outside collection of collection rain dish and crown canopy rain dish is collected being incorporated into two collects in graduated cylinders 5.Described collection graduated cylinder 5 is vertically fixed on bearing 6, and adopts transparent material, is designed with scale on vertical direction, realizes the statistics directly perceived to the collection graduated cylinder 5 interior water yields.
The utility model rainfall acquisition and recording device, in use, after pressure pin 2 is supported by pressure pin support 1, make crown canopy below collection rain dish and the outside collection of crown canopy rain dish lay respectively at crown canopy lower zone and the outside spacious region of crown canopy, realize crown canopy block under condition with the unobstructed condition of spaciousness under the while with the rainfall collection in border.The rainwater in the outside spacious region of crown canopy lower zone and crown canopy falls into respectively crown canopy below collection rain dish and the outside collection of crown canopy rain dish, final, through crown canopy below rainfall guiding tube and the outside rainfall guiding tube of crown canopy, flows in two collection graduated cylinders 5; Comparison by water yield volume in two collection graduated cylinders 5, can precisely draw rate of canopy interception.
