Abstract

The utility model discloses a snow-thawed double-cabin rain and snow gauge, which solves the problem of the common tipping-bucket snow-thawed rain and snow gauge that the snow on the surface on a hopper is thawed under heat but the snow water in the hopper is frozen. The snow-thawed double-cabin rain and snow gauge adopts a double-cabin structure, wherein the part above a pedestal is used as a work cabin, which mainly includes a hopper, a tipping bucket, a water discharge tank, etc.; the part below the pedestal and above a base is used as a heat insulating cabin, which includes a water storage barrel, a globe valve, a water exhaust pipe, etc. The work cabin is communicated with the heat insulating cabin only through a flow guide pipe, and the heat insulating cabin is communicated with the outside only through the water exhaust pipe. The heat insulating cabin forms a barrier between the work cabin and the external cold air to prevent the cold air from directly invading the work cabin, thereby effectively preventing and obviating the snow water in the work cabin from being frozen, and ensuring normal observation of the instrument.

Description

The two cabins of snow melt type moisture conditions meter

One, technical field

The utility model relates to the two cabins of a kind of snow melt type moisture conditions meter.Be mainly used in industries such as meteorology, the hydrology, forestry, agricultural, environmental protection, the sight (prison) of rainfall, snowfall is surveyed.

Two, background technology

Snow melt type moisture conditions meter is widely used in industries such as northern China and extremely frigid zones meteorology, the hydrology, forestry, agricultural, environmental protection, and the sight (prison) of rainfall, snowfall is surveyed.

Common snow melt type moisture conditions meter is to increase heating arrangement on the basis of tipping-bucket rain-gauge.Its heating snow melt, snow-broth metering, functions such as snow-broth drainage all concentrate in the cabin body.

The structure of common tipping bucket type snow melt type moisture conditions meter as shown in Figure 1.Descend slowly and lightly in the snowfall of funnel (2) through holding the mouth of a river (1), under the heat effect of heating plate (4), melt and to be liquid water, flow in the chamber that is filled with water about tipping bucket (7) one of them by funnel water delivering orifice (6), when snow-broth reaches a certain amount of, tipping bucket overturns, snow-broth pours into out in the water pot (8), and another chamber of being filled with water of funnel begins again to be filled with water, in the switching process, the permanent magnet and the interaction of the tongue tube on the support that are fixed on the tipping bucket produce a pulse signal, finish once metering.Overturn again and again by the chamber of being filled with water about tipping bucket, finish metering snowfall collected in the funnel.

The snow melt type moisture conditions meter of this structure, be simple in structure and convenient in use, but also have weak point, its shortcoming is: cold air can directly be invaded in the cabin by the mozzle that goes out water pot (8) (9), makes near the temperature of tipping bucket very easily be subjected to the influence of cool ambient air, in the winter time during cold wave, funnel surface heating snow melt appears often, the phenomenon that tipping bucket the inside snow-broth freezes, the catastrophic failure that can't overturn in the chamber that causes being filled with water about tipping bucket, the snow-broth metering process stops, and snowfall observation was lost efficacy.

Three, summary of the invention

The technical problem to be solved in the present invention is exactly under the situation that does not increase the heating plate power consumption, avoid and overcome the phenomenon of above-mentioned " funnel surface heating snow melt; tipping bucket the inside snow-broth freezes ", make tipping bucket type snow melt type moisture conditions meter in heating snow melt, tipping bucket metering process, keep the liquid form of snow-broth all the time, thereby ensure the normal operation of instrument.

Concrete measure is: adopt two cabin structures, the structure of the two cabins of snow melt type moisture conditions meter is about to the above part of original tipping bucket type snow melt type moisture conditions meter base (12) as shown in Figure 2 as work chamber.Promptly by the funnel below, above the base, the space that relevant cylinder inboard wall is constituted mainly comprises: funnel (2), and tipping bucket (7) goes out water pot parts such as (8); A water butt (14) that is fixed on pedestal (17) and the valve of dribbling control draining is set up in the base below.Below the base (12), more than the pedestal (17), and the space that relevant cylinder inboard wall constituted is as insulated hold, and it mainly comprises water butt (14), ball valve (15), drainpipe parts such as (16).Only depend on out the mozzle (9) of water pot (8) to communicate between work chamber and the insulated hold; Insulated hold only communicates with the external world with drainpipe (16).

The beneficial effects of the utility model are: the insulated hold behind the two cabin structures of employing has constituted barrier at work chamber between cool ambient air, stopped the direct intrusion of cold air to work chamber, do not increasing under the situation that adds heat power consumption, even if in the winter time during the cold wave, also can prevent and avoid the snow-broth in the work chamber to freeze effectively, thereby ensure instrument normal observation in the winter time.

Four, description of drawings

Below in conjunction with accompanying drawing the present utility model is described further.

Five, embodiment

As shown in Figure 2: descend slowly and lightly snowfall on funnel (2) surface under the heat effect of heating plate (4) through holding the mouth of a river (1), melt and be snow-broth, through funnel water delivering orifice (6), flow to tipping bucket (7), after tipping bucket upset metering, snow-broth is introduced into out water pot (8), is flowed in the water butt (14) by its mozzle (9).Because the buoyancy of snow-broth, ball valve (15) are risen and raised, liquid snow-broth is leaked by drainpipe (16), after snow-broth has been let out, ball valve (15) under the effect of himself gravity, shutoff drainpipe (16) voluntarily.

Airtight relatively air bolus in insulated hold, under the acting in conjunction of factors such as ball valve, make insulated hold between cool ambient air, constitute barrier at work chamber, stopped the direct intrusion of cold air to work chamber, under the situation that does not increase power consumption, even if during the cold wave, also can prevent and avoid the snow-broth in the work chamber to freeze effectively in the winter time, ensure instrument normal observation in the winter time.

Claims

The two cabins of a kind of snow melt type moisture conditions meter, the part more than its base (12) mainly comprises as work chamber: funnel (2), tipping bucket (7) goes out water pot parts such as (8); Base (12) below is provided with an insulated hold, it is characterized in that, and described insulated hold, by water butt (14), the ball valve of automatic open close (15), pedestal (17), drainpipe parts such as (16) constitute; Only depend on out the mozzle (9) of water pot (8) to communicate between work chamber and the insulated hold: insulated hold only communicates with the external world with drainpipe (16).
