4, the half-closed protective cover of described sampling bottle top installation.
Advantage of the present invention is:
1. some vitals all are equipped with protective cover among the present invention; Like each collection rain drain bucket, sampling bottle; It can be operated in outdoor rugged surroundings all the year round, and some zero, parts damages of having avoided high temperature, Exposure to Sunlight and having drenched with rain and often cause have strengthened reliability and serviceable life.
2. sealing property of the present invention is perfect, and each seals at pressing is tight, even, seamless, has guaranteed the appropriate preservation of sample rainwater, and the material of the pipeline of all rainwater processes is the corrosion-resistant plastic material, has guaranteed serviceable life.
3. bottle distributing mechanism among the present invention and switch cover mechanism are simple and practical, under structure is tried one's best simple situation, accomplish perfect sampling, adopt motor-driven to guarantee its combination property.
4. the present invention can carry out the collection of rainwater automatically when precipitation, stops sampling after rain stops automatically, can preserve sample well behind the completion collection work, and can write down the data relevant with precipitation.
5. the present invention can store and check the rainfall play of sampling thief record, start time, concluding time, temperature, rainfall amount and the fault alarm of every rainfall through certain mode; Be provided with the collection segmented model, can be according to concrete chopping rule with the rainwater of the different sections different container of packing into.
6. dependable performance of the present invention, with low cost, practicality is high, and installation, carrying and maintenance are all simple relatively.

Fig. 2 is a left-hand cut-open view of the present invention;
Fig. 3 is a vertical view cutaway drawing of the present invention.
Embodiment
For example the present invention is done description in more detail below in conjunction with accompanying drawing:
In conjunction with Fig. 1～3, mainly comprise physical construction and control system two large divisions, control bottle distributing mechanism and switch cover mechanism through sensor signal and realize that concrete action has reached the purpose of gathering the rainwater sample.Its primary structure comprises bottle distributing mechanism, switch cover mechanism, sensing system mechanism, motor-driven mechanism, reaches instrument support frame etc.The profile main body is cylindric, highly is about 800mm, and radial dimension is 400mm approximately, is provided with single handle and double handle, convenient in carrying; 6 sampling bottles 15 evenly are fixed in around the mounting platform, and each sampling bottle 15 top all is equipped with half-closed protective cover, shield, and sampling bottle is installed and take off all very convenient, can be directly from peripheral operation; What distribute alternately with bottle is No. six drainage pipelines, and its effect is to collect when full when sampling bottle, drains remaining rainwater.
Be provided with dust cap; When equipment time spent not, prevent the inner air that gets into of sampling thief, pressing is closely, evenly between dust cap inside surface and encapsulant; Seamless; Lid is buckled on the rain sampling funnel, and the outer wall of its inwall and funnel fits with the form of inclined-plane (occurring stuck phenomenon when the inclined-plane form can prevent to uncap), to guarantee Seal of Equipment property.
Profile main body of the present invention is cylindric, is provided with single handle and double handle, convenient carrying; Equipment is the time spent not, has lid 7 that sampling thief inside is covered and seals, to prevent the inner air that gets into of sampling thief; 6 sampling bottles 15 evenly are fixed in around the mounting platform, and each sampling bottle 15 top all is equipped with half-closed protective cover, and what distribute alternately with bottle is No. six drainage pipelines, and its effect is to collect when full when sampling bottle, drains remaining rainwater.
When rainwater landed, the rainwater that funnel 6 is collected can be along channel flow to pipeline, and the rainwater outlet is blocked; And funnel can continue to collect rainwater, and when the liquid level rising, the air of the pipeline that links to each other with pressure transducer 5 the inside is caught in; Pressure rises, this moment, pressure transducer 5 just can perceive the beginning rainfall through the pressure variation, and sensor sends signal; Single-chip microcomputer receives the rainfall signal and carries out next step action according to deciding program; Be designed with leak conduit, when falling when raining heavyly, rainwater flows away from leak conduit.
After single-chip microcomputer received the rainfall signal, switch cover mechanism and bottle distributing mechanism were started working.Lid 7 is buckled on the collection rain drain bucket 8, and motor 17 is fixed on the back up pad with motor 9.Motor 17 will rotatablely move through screw-nut body 16 and become rectilinear motion; Driving act bar 11 realizes moving up and down; Motor 9 rotates a certain angle lid through gear drive, the inner sealing of post-sampling device thereby the collection and the collection that realize rainwater finish.The turned position restriction of motor 17 and motor 9 is controlled by limit switch.When sampling bottle 15 is not collected completely, along with the injection of rainwater, can the air in the sampling bottle be extruded, when sampling bottle is collected completely; Liquid level rises in the water injecting mechanism 12, and " sampling bottle is full " signal is sent in sensor 4 perception copper foil conductings; After single-chip microcomputer was received this signal, control motor 1 drove bottle distributing mechanism, and turntable 13 turns over 30 degree; Filling pipe is aimed at drainage pipeline, will remain the rainwater emptying, prepares precipitation collection next time.Antirust electromagnet has been installed at the rear portion of water injecting mechanism 12, and when the rainwater collection was full, to the electromagnet energising, the water delivery bar disengaged with connecting duct under magneticaction.Like this, turntable can drive water injecting mechanism like a cork and rotate and do not interfere with sampling bottle, and the resetting of water injecting mechanism is to lean on the elastic force of compression spring to realize.
When rainfall finished, rainwater can flow away through the aperture that is connected with pressure transducer 5 faster, and along with liquid level descends, air reverts to normality from squeezed state, and pressure descends, and pressure transducer 5 comes the perception rainfall to finish through this variation.
