Specific embodiment
The optimal technical scheme that according to the present invention will be described in detail below with reference to the accompanying drawings.
A kind of pressure sensing type type rain-snow gauge device of the utility model, by real-time signal transition detection precipitation,
For monitoring the instrument of the snowfall in meteorology, rainfall, belong to electronic communication, automatic control control, hydrology class field；Present apparatus benefit
With pressure sensor conversion signal, precipitation flow velocity is not-easy-to-freeze fastly, and anti-pressure ability is strong, plays a protective role to device, knot
MCU automatic control switch, water valve are closed, the accurate device of sleet capacity is quantitatively calculated, it is novel in design unique.
The purpose of the utility model is to overcome discharge outlet of the existing technology easily to block, measurement accuracy inaccuracy etc. is asked
Topic, provide a kind of design rationally, quantitative, the process circulatory monitoring of sleet mixing Precipitation Process can be completed, meet precision
Pressure type type rain-snow gauge device.
As shown in Figure 1, a kind of pressure sensing type type rain-snow gauge, including stack shell part and metering section.In order to avoid heavy rain
Or heavy rain overflows, and is one large-scale capacity groove in the top of protection cylinder, that is, be filled with water mouth 1, can be used to be filled with water, avenge, under abutting
Face is a funnel 2, and 2 upper surface of funnel is provided with insect prevention silk screen, and the outer cavity surface layer of funnel 2 is provided with temperature control heating element 4 and is used to
Snow melt, water flow keep clear, and 2 water outlet bottom right end flush portion of funnel is a good elastic slice by switch control of elasticity
5, it is single to be provided with leveling above, a hopper 6 immediately below water outlet, while being used to water storage, the hydraulic pressure force signal that constantly injects
MCU controller 3 is sent to by sensor, and 3 electric signal of MCU controller controls elastic slice 5；
Further, 6 side of hopper is equipped with fast decompression water valve 10, at the discharge outlet of graduated cylinder lower right side, quickly
Decompression 10 top of water valve is connected with relay 9, carries out current control, adjusts circuit.Relay is wired to positioned at cylinder
On the MCU controller 3 in wall upper right side, it is pressure sensor 7 immediately below hopper 6, detects the water in hopper 6, and will be real
When signal be converted into electric signal and be sent to MCU controller 3, relay 9 controls fast decompression water valve 10 and is opened and closed.
Further, elastic slice 5 is controlled by the elastic switch on right side, and switch is controlled by MCU, and elasticity is good.5 material of elastic slice
Itself keeps flushing with water pipe lower end, precision fitting, and hydrophobicity is good.
As shown in Fig. 2, pressure sensor 7 believes pressure when the hydraulic pressure force signal in hopper 6 is G (water does not overflow)
Number electric signal transmission is converted into MCU controller 3.After MCU controller 3 receives signal, elastic slice 5 is popped up, is blocked under funnel 2
(elastic slice hydrophobicity is good, high with the horizontal compatible degree of water outlet, and hydraulic pressure belongs to can be in tolerance range, it is believed that will not leak for the water outlet at end
Water), while the fast decompression water valve 10 of 6 bottom righthand side of hopper is opened, it can be in a relatively short period of time by water discharge (quantitative draining).
When the water in graduated cylinder 6 is drained, pressure value 0, pressure sensor 7 sends signal 2, after MCU controller 3 receives signal, closes
Fast decompression water valve 10 rebounds elastic slice 5, and circulation starts the Rainfall estimation of a new round.The liquid crystal being connected with MCU controller 3
Show on device with counter device, shows the number of draining.
Illustrate: stack shell is topmost that large capacity is filled with water mouth 1, and bottom water valve is that the draining of fast decompression water valve is fast, therefore i.e.
Make when rainfall is bigger, the mouth 1 that is filled with water can accommodate, and precipitation does not overflow.
