Abstract
Disclosed is an atmometer for measuring evaporation capacity in forest, comprising an unglazed pottery pipe, a compensating pipe, a container bolt, and a breather pipe. According to the technical scheme of the utility model, the unglazed pottery pipe is arranged above the water surface. When the water inside the unglazed pottery pipe is evaporated due to the external environment, the water inside the container is effectively led into the interior of the unglazed pottery pipe, thereby realizing the effect of compensating water. The atmometer features small and simple structure, low cost, and convenient maintenance, and is applicable to the observation of the evaporation capacity inside the forest in various regions.
Description
Technical field
The utility model relates to a kind of evaporimeter for observing in the woods, relates in particular to a kind ofly not affected by rainfall etc., and is easy to maintenance, constructs observation evaporimeter in the easy woods.
Background technology
Photosynthesis from forest can learn that the uptake of carbon dioxide and the growing amount of oxygen are directly proportional with the consumption figure of insolation amount and water.Therefore, if by measuring the evaporation capacity of forest, can obtain the light compositing amount of forest.The evaporation capacity of measuring forest plants can play protection, applies flexibly the effect of the forest reserves.Evaporation capacity in the mensuration woods is particularly important for protection and the applying flexibly of earth resources of earth environment.And the instrument of measuring evaporation capacity evaporimeter just, traditional evaporimeter is evaporating dish, and use principle is to be 120 centimetres at bore, and the degree of depth is to fill water in 25 centimetres the evaporating dish, and the slippage of water level is evaporation capacity.
The present invention is particularly useful for not having in the forest of source power supply, even nobody also can carry out long-standing observation on the side.This provides and can compare different soils, the evaporimeter of the evaporation capacity of different plants.This evaporimeter cost is low, can be used in more place, can carry easily, place, and be the advantage of Observable etc. as long as be suspended on the branch.Because water can not overflow disengaging surface, thus be difficult to be subject to the impact of rainfall, and be difficult for being detained foreign matter, easy to maintenance.
Summary of the invention
The purpose of this utility model is to provide a kind of evaporimeter for evaporation capacity in the observation woods, and this evaporimeter has simple in structure small and exquisite, and is easy to install and use, and being suspended on the branch is observable advantage.
The purpose of this utility model can realize by following technical measures: the evaporimeter structure comprises plain earthenware pipe, compensating pipe, container bolt and snorkel, plain earthenware pipe is placed in water surface top, the upper end of compensating pipe and plain earthenware pipe join, the lower end is immersed in the water, come the lower end of sealing compensation pipe with bolt, tubule runs through bolt and the lower end is immersed in the water.Evaporimeter not only has the container bolt of sealed container port, and makes in addition the upper space of the water surface in the container and the snorkel that outer gas is communicated with, and compensating pipe and snorkel can run through the container bolt, and the outstanding snorkel of container bolt is barb shape.When the water in the plain earthenware pipe was evaporated because of external environment influence, the water in the container can import the inside of plain earthenware pipe effectively, thereby reaches the purpose of compensation water.
Description of drawings
Accompanying drawing 1 is the structure principle chart of observation evaporimeter in the utility model woods.
Embodiment
Below in conjunction with accompanying drawing 1, the utility model is done further detailed description: enter water such as 6 in the container 4 interior Shengs of tygon system, the mouth of container 4 is that the container bolt 3 by rubber system reaches sealing; In the container bolt 3, run through the compensating pipe 7 of synthetic resin (such as the sclerosis vinyl) system; Having fixed xsect in the upper end of compensating pipe 7 with sticker is the plain earthenware pipe 1 of anti-U word shape; The lower end of compensating pipe 7 is furnished with bolt 8; Tubule 5 runs through bolt 8; The lower end of tubule 5 has been immersed in the water 6 in the container 4; Container bolt 3 has run through the snorkel 2 that the upper segment space that makes the water surface in the container 4 and outer gas are communicated with; What form from the snorkel 2 of the outstanding part of container bolt 4 then is the shape of barb 2a.
Below explanation is the using method of this evaporimeter: at first in container 4 interior Sheng entry 6; Then the compensating pipe 7 of make container bolt 3, reserving, be fixed on plain earthenware pipe 1 on the compensating pipe 7 and snorkel 2 and be integrated and stand upside down; There is water 6 inside of the inside of compensating pipe 7 and plain earthenware pipe 1, next, the tip of tubule 5 is immersed in the water; Afterwards, by the mouth that is installed in bolt 8 on the tubule 5 and clogs compensating pipe 7; Make it upright after container bolt 3, compensating pipe 7, plain earthenware pipe 1, snorkel 2, bolt 8 and tubule 5 are integrated, use again the mouth of container bolt 3 airtight containers 4 after upright.
After this, evaporimeter is positioned over measurement ground.This moment, the tip because of snorkel 2 formed barb 2a, was quite easily so hang evaporimeter at branch.If measuring ground placement evaporimeter, water will be from the surface evaporation of plain earthenware pipe 1, and the water in the tube wall of plain earthenware pipe 1 will reduce, and because of the tube wall of the wetting plain earthenware pipe 1 of water meeting, the water in the container 4 will be by the internal compensation water of tubule 5 to plain earthenware pipe 1.Namely as long as the lower end of tubule 5 has been immersed in the water 6 in the container 4, water 6 will be given plain earthenware pipe 1 internal compensation water.
Therefore, just can learn 1 day evaporation capacity such as the reduction of regularly measuring the water 6 in the container 4 every day.The concrete assay method that can adopt: container 4 is partially transparent or translucent at least, engraves scale at transparent part, just can measure front 1 day reduction by scale.The weight inductor hung barb 2a if be situated between this moment, by the signal of weight induction device is sent to isolator, did not just need the special of other side to manage in the compensation water timesharing.
Implement by above-mentioned example, just can apply flexibly the evaporimeter of this simple structure.The tube wall of factor earthenware pipe 1 also can flow backwards even rainfall water occurs often by water-wet, and the water yields in the container 4 neither can increase and also are difficult to have foreign matter to adhere to.Therefore can say that this evaporimeter is difficult to be subject to the impact of rainfall etc., daily maintenance is very convenient.
