Description

Evaporate measurer

Technical field

Present invention evaporation measurer related, in particular to a kind of with hydrographic survey utensil.

Background technique

The lifting of river and lake water level is the thing that people especially hydrologist pays special attention in flood dry season, evaporation capacity compared with Big arid area or season, the holding of ground water system water level and SEA LEVEL VARIATION and the nature ecological balance, industrial and agricultural production are very It is all closely bound up to daily life, it is accurate measurement and the palm of the evaporation capacity in daily or a period of time to water level decreasing It holds very necessary；And in actual life, the measurement of relevant departments is more extensive, and technical way is exactly that foundation is planted in water body In gauge on water level in several days decline variation generally estimated again to read measured value, in fact, every In the case where the day even smaller evaporation capacity variation of several millimeters, to read one day measured value and be difficult, needless to say have Can be more difficult in the case that the stormy waves water surface is uneven, so, a kind of measuring appliance that can accurately predict surface water body evaporation capacity is People especially professional person intentionally gets.

Summary of the invention

The purpose of the present invention is to provide a kind of evaporation measurer, it can solve aforementioned problem.

The content of technical solution of the present invention is as follows: it includes column, floating drum, graduated cylinder, the cover, regulation pipe, under the column End is fixed on water-bed riverbed by plant, and the threaded upper ends of column are connected to a regulation pipe；The floating drum is with upper bottom Transparent cylindrical shape, wherein the bottom of floating drum be provided with it is multiple it is equally distributed perforation and the center portion thereof position is fixed to The top of regulation pipe, the floating plug that one matches with the cross sectional shape of floating drum is provided in floating drum and floating plug can be in floating drum with water Buoyancy size and go up and down, the upper bottom center of floating drum be connected with one section it is upright vertically upward on top with the circular of the cover Transparent graduated cylinder, the diameter of graduated cylinder be less than the diameter of floating drum and be connected in floating drum, have water in floating drum, graduated cylinder；When water level is because steaming Floating plug can also accompany and drop and the height number of decline be amplified more times from the SEA LEVEL VARIATION in graduated cylinder when the reason of hair declines Reflect.

The beneficial effects of the present invention are: it can accurately especially carry out fluctuation in stage to water level decreasing, that is, evaporation capacity Measurement.

Detailed description of the invention:

Attached drawing is the plan view in the design measuring appliance vertical section.

In figure, 1 is the cover, and 2 be graduated cylinder, and 3 be floating drum, and 4 be floating plug, and 5 be column, and 6 be riverbed, and 7 be regulation pipe.

Specific embodiment

The design is given an example with reference to the accompanying drawing.

As shown, the measuring appliance of the design includes column 5, floating drum 3, graduated cylinder 2, the cover 1, regulation pipe 7, the column 5 Lower end transplanted and be fixed on water-bed riverbed 6, the threaded upper ends of column 5 are connected to a regulation pipe 7, if regulation pipe rotates It can be just set to obtain the adjusting relative to column or liter or the height and position of drop；The floating drum 3 is one with the saturating of upper bottom Bright cylindrical shape, wherein the bottom of floating drum is provided with multiple equally distributed perforation, and the center portion thereof position is fixed in the bottom of floating drum To the top of regulation pipe 7, it is provided with the floating plug 4 that one matches with the cross-sectional shape of floating drum inner cavity in floating drum 3 and floating plug can To go up and down in floating drum with the buoyancy size variation of water, the Material Processing of floating plug should select waterproof, light and tissue stabilization Material, such as hollow silica gel material, polyester foamed material etc., they can carry out its wall surface high-precision smooth It processes to be fit to the inner wall of floating drum, so that floating plug can not only go up and down with the buoyancy size variation of water in floating drum but also can be really The water protected above floating plug will not be lost by seepage flow under the bonding gap between floating drum inner wall and floating plug wall surface；In the upper bottom of floating drum The heart is connected with one section of circular transparent graduated cylinder 2 on top with the cover 1 upright vertically upward, and the diameter of graduated cylinder is less than floating drum Diameter and be connected in the cylinder of floating drum, have water in floating drum, graduated cylinder；When water level because the reason of evaporating, declines when floating plug also can phase With and drop and the height number of decline amplified to more times from the SEA LEVEL VARIATION in graduated cylinder and reflect；Specifically it is set using When, as shown, needing the lower part of the floating drum of measuring appliance one section is submerged in water, while should be noted that floating plug will be in floating drum Intermediate position can pass through floating drum without upward, the downward upper and lower bottom for touching floating drum if the malposition of floating plug 3 drive the rotation of regulation pipe 7 to come the relative altitude position between adjusting post 5 and regulation pipe 7, namely have adjusted floating drum in the water surface Height and position and and then have adjusted the size of buoyancy suffered by floating plug 4, have adjusted the height and position of floating plug, until adjusting to being in At the height appropriate of the middle section of floating drum, move place thus is provided for the lifting of floating plug, otherwise can not accurately be surveyed Amount；The cover can be opened to facilitate the water that normal loss missing is filled the water and supplemented into graduated cylinder, while it again can be to greatest extent The evaporation for reducing water in graduated cylinder, reduction has an impact the water level in graduated cylinder, to reduce to the disturbing factor of accurate measured value； Floating plug institute when the water surface site of water body in one day or a period of time, which changes, such as to be declined because largely evaporating, in floating drum The buoyancy being subject to will accompany naturally reduces simultaneously falling head, in the reflection to the water level in graduated cylinder cylinder that this variation can be inevitable, When the SEA LEVEL VARIATION value in graduated cylinder is measured, such as the 10mm that has been water level decreasing, since the diameter of graduated cylinder is less than the straight of floating drum Diameter, the cross-sectional area for setting graduated cylinder is that the 1/100(of floating drum lumenal cross-section area can set its diameter ratio as 1/10), The height and position that the actually water surface can then be conversed has dropped 10/100, i.e. 0.1mm, this graduated cylinder and floating drum cross section Even small and big setting cooperates so that small fluctuation in stage can also be amplified 100 times, this just greatly facilitates measurement and sees It examines, meanwhile, on having the calmness for being applied to the water surface in graduated cylinder that will not be too big influence being beaten by wind and waves and stablizing, this can Accurately the variation numerical measuring of height of water level to be read；Certainly, it is known that above-mentioned section ratio can also be in cylinder scale On directly indicated by the numerical value after conversion, for example, the actual height of water level decreasing in graduated cylinder 10mm is then denoted as 0.1mm Height change, thus can directly read actual evaporation measuring value, no longer need to convert.
