Abstract
The invention discloses a rainfall detection device which comprises a housing, a water container, a siphon and a camera. The water container inside the housing is connected with the top of the housing through a funnel, and the lower portion of the water container is further connected with a pressure sensor. The pressure sensor and the camera are simultaneously connected to a data acquirer located inside the housing. An access hole is further formed in the side face of the housing. By the adoption of the structure, the rainfall change situation can be detected, the change situation of a surrounding geological disaster can be also monitored, and transfer is performed remotely to facilitate later reasonable taking of recourse measures according to the situations of the rainfall and the surrounding geological disaster. In addition, due to the fact that the access hole is further specially formed for the rainfall detection device, later local overhaul is facilitated, and the using cost is reduced.
Description
Technical field
The present invention relates to Geological Hazards Monitoring field, be specifically related to rainfall detection device.
Background technology
Man of Shi Yigeduo mountain country of China, mountain region, plateau and hills account for 69% of area, all produce the geologic hazards such as a large amount of avalanches, landslide and rubble flow every year. and a main predisposing factors of the disasters such as avalanche, landslide and rubble flow is rainfall. therefore, how to obtain rainfall data in real time, accurately, early warning work for geologic hazard seems particularly important. rain gage is the instrument of the measurement precipitation that meteorology and social each relevant departments generally apply, and total is divided into manual measurement and sensor measurement two kinds of modes.And sensor measurement such as can be subdivided at polytype rain gage.But the rain gage of every type has certain defect in precision or operability, is not very perfect. the precision that such as tipping-bucket rain-gauge is measured is subject to the restriction of rainfall intensity size, and rain is larger, measures more inaccurate; And siphon rainfall recorder needs regular field notes to measure and change recording chart, this brings inconvenience to field monitoring; Ultrasonic Rain Gauge then affects due to the factor such as density, concentration, temperature, pressure of hyperacoustic velocity of propagation by medium, and its measuring accuracy is lower.Existing various rain gage only can realize rainfall measurement function in addition, if breaking down in inside is also not easy to maintenance, whole rain gage can only be changed, use cost is higher.
Summary of the invention
Instant invention overcomes the deficiencies in the prior art, rainfall detection device is provided, this rain gage can not only measure the situation of change of rainfall, the situation of change of geologic hazard around can also be monitored, transmitted by long-range, so that the later stage rationally adopts the measure of requiring assistance according to rainfall and surrounding geology disaster scenarios it, this rain gage also arranges access hole specially in addition, facilitate the later stage to carry out local overhauling, reduce use cost.
For solving above-mentioned technical matters, the present invention is by the following technical solutions: rainfall detection device, comprise housing, water container, U trap and camera, connected by funnel between described enclosure interior water container and case top, go back Bonding pressure sensor in the below of water container; Bonding pressure sensor and camera simultaneously on the data acquisition unit being positioned at enclosure interior; The side of described housing also arranges access hole.
When starting rainfall, outside rainwater is beaten in case top, enters in water container through funnel, water level in water container rises gradually, when rainfall amount reaches siphon point height, water just can be discharged by U trap by the water in water container, and the water level in water container also just have dropped accordingly.When beginning to rain and rainfall amount does not reach siphon point height, but the voltage data of the single-chip microcomputer that rainfall amount so during this period of time can be passed on data acquisition unit by pressure transducer converts out. when rainfall amount reaches siphon point height, when starting to occur siphonage, rain gage is just operated in a kind of one side water receiving while the state that discharges water. because the speed of U trap draining is much larger than the speed of rainfall, water in final water container still can be discharged, just the time of draining is a little longer than siphon drainage time when not having rainfall, according to this rule, utilize existing computing formula can draw the change information of final rainfall, long-range transmission is realized by the gsm module on data acquisition unit, without the need to field notes data, realize remote monitoring.Data acquisition unit also arranges the situation of change of camera for geologic hazard around monitoring, is transmitted by long-range, so as the later stage according to rainfall and around geology disaster scenarios it rationally adopt the measure of requiring assistance.And the access hole that housing is arranged, when rain gage generation abnormal conditions, by taking access hole apart to realize, local overhauling being carried out to rain gage inside, without the need to replacing whole rain gage, reducing use cost.
In order to ensure that rain gage can steady operation in the wild, the electric energy that supply is sufficient, realizes running well, described data acquisition unit also connects solar panel.
Conveniently observe the situation of change of the information such as the water level of rain gage inside from outside, described access hole also arranges liquid level line.
Described housing comprise the lid at top, middle part hold cavity and base, lid wherein, hold cavity and base connects as one structure successively, the width of lid is greater than and holds cavity, and the whole cavity that holds is covered on below.Lid can be protected and wholely hold cavity, avoids holding in rainwater in the gap that cavity and lid formed entering, and ensures the accurate of measurement result.
Because water column residual in U trap can affect the precision of measurement result, can normally siphon and without weeping, simultaneously after siphon is complete, also can not remain water column in pipe in order to ensure that rainfall reaches siphon point, described U trap is bend pipe, and the arc range of bend pipe is between 29 °-31 °.
Described camera is that all-directional rotation is without dead angle camera.Can the image information of more omnibearing collection geology disaster region, be transferred to remote terminal and use, better to formulate effective rescue measure.
Compared with prior art, the invention has the beneficial effects as follows:
1, this rain gage can not only rainfall information collection, can also gather the environment change information around geologic hazard, be transmitted by long-range, so as the later stage according to rainfall and around geology disaster scenarios it rationally adopt the measure of requiring assistance.
2, on udometric housing, access hole is set specially, conveniently can also observes inner water yield situation of change, the later stage can also be facilitated to carry out local overhauling, reduce use cost.
