The purpose of this utility model, it is simpler to aim to provide a kind of structure, cost is lower, energy consumption is less, safeguard and be easy to novel air precipitation (acid rain) automatic sampler, by the design of innovation, only use a cover motor, transmission and control system to realize the function of above-mentioned raising sampling container relative height suitable for reading, the sealing of Reinforced container lid equally.
The technical scheme of this atmospheric precipitation (acid rain) sampling thief is achieved in that and comprises sampling bucket (or funneling collection rain device) in its structure; the container cover that can vertically rotate, main shaft, rain sensor (charged in case of necessity heating arrangement and temperature controller), electronic controller, reversible electric machine and variable ratio drive system, the motor protecter of " " type handler, band evener, travel switch and (seeing accompanying drawing 1) such as garden disc type position-limit mechanism, support and shells.It is characterized in that, " " type single-handle turning mechanism that employing is vertically rotated around single shaft, only with very having solved the sampling container problem that must be higher than sampling thief main frame surface and strengthen the bung sealing suitable for reading easily once cover motor and transmission, control system, and must not adopt two cover motors, kinematic trains, thereby simplified structure, reduce energy consumption, reduce cost, reduce fault.Simultaneously, this sampling thief has adopted balance bob in rotating mechanism, with the rotating torque of reducing mechanism as far as possible; Design garden disc type position-limit mechanism, can determine the final position of container cover switch more accurately, reliably.This sampling thief is when cold district uses, and the optional sensor special of wearing electrical heating and temperature controller so that when temperature is lower than 0 ℃, dissolve ice and snow with Electric heating, makes this sampling thief also can be used for the snow-broth sampling.Overcome some automatic samplers commonly used and can not be used for the weakness that snowfall is sampled.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the embodiment of a kind of concrete structure of the utility model.
Fig. 2 is the vertical view of Fig. 1.
Referring to Fig. 1 and Fig. 2, this device by: the support (2) of sampling bucket (1), a supporting, fixed sample bucket, sampling bung (3), with " " type handler (4) that the sampling bung is connected, handler and balance bob (5) are fixed on the main shaft (6).Main shaft then reaches the column that links to each other with axle sleeve by axle sleeve (or bearing) (7), is fixed on the support.The related bung of " " type handler can rotate in vertical direction with main shaft together, makes bung open or close.The garden disc type stop means that two spacing collision blocks (8) are housed that is connected with main shaft---positioning disk (9) cooperatively interacts with two travel switches (10) that are fixed on the support, final position when accurately the qualification bung is opened or closed, reversible electric machine (10) links to each other with main shaft by speed reduction gearing (12), shaft joint (13), for the switch of bung provides power.Sensor (14), electronic controller (15) and motor protecter (16) are installed in the appropriate location of sampling thief.The sampling thief casing provides safeguard function for the electrical equipment in the sampling thief and parts, and in addition, important electrical equipment (as sensor, electronic controller, travel switch, motor and gearing motor protecter etc., also is furnished with special-purpose protective cover.
In case rain, after the sensor conducts, the electronic controller that is attached thereto sends signal, start reversible electric machine, bung is opened.Bung is opened to the precalculated position, and " positioning disk " goes up collision block, touches travel switch, motor is stopped transport.Rain stops back a period of time, and after sensor electrode opened circuit, controller sent signal once more, made the reversible electric machine backward rotation, and bung is closed.Another collision block on the positioning disk touches to close and covers travel switch, and motor is stopped transport, and rotation system is accurately positioned in predetermined Guan Gai position.
Because " " type of employing rotating mechanism, the bung and the main shaft of normal closed condition can be on surface levels.Device must two cover motors and kinematic train just realized the requirement that is higher than the main frame plane suitable for reading of sampling bucket.Simultaneously because rotation axis is designed to single shaft and vertically rotation, bung can be designed to be with sagging edge, thereby realizes dual face seals, has better sealing property than the single face sealing of general sampling thief, before significantly reducing rain, behind the rain in the air dust and sour gas to the pollution of institute's water sampling.
Design has more than one balance bob (generally at least two) to reduce the rotating torque of mechanism as far as possible in whole rotation process on the device main shaft, reduces motor load, and makes system's operation more steady, reliable.
Garden disc type position-limit mechanism---the effect of " positioning disk " is to match with travel switch, determines the final position of container cover open and close accurately, reliably.
Also electric heater unit can be set in the sensor in case of necessity.It acts on when using the surface-type electrode sensor, can quicken water evaporates, shortens the interval time before rain stops back to pass lid.When cold district used this sampling thief, the also optional sensor special of wearing temperature controller so that when temperature is lower than 0 ℃, dissolve ice and snow with Electric heating, made this sampling thief also can be used for the snow-broth sampling.Overcome some automatic samplers commonly used and can not be used for the weakness that snowfall is sampled.
Referring to Fig. 3, this is another embodiment of the present utility model.And the difference of previous embodiment is: increased the one-level belt drive system between mechanical variable speed device and main shaft.Though structure slightly complicated like this; but reduced requirement to mechanical transmission (when directly using mechanical transmission; generally need secondary transmission, and supporting with belt gear, the one-level variator gets final product); and belt drive system has certain defencive function to motor; when device there was a mechanical failure, during stuck can't the rotation, belt pulley can skid, and makes motor also unlikely stuck; help to protect motor, reduce the danger of burn-down of electric motor.In the present embodiment, spacing collision block (8) is directly installed on the big belt pulley (17) that is connected with main shaft, and promptly big belt pulley has been brought into play the effect of " positioning disk " simultaneously.
