Abstract

The utility model relates to a rainfall monitoring field especially relates to the rainfall monitoring devices who is used for geological disasters, and the needle top arranges at the casing top that the base arranges in the casing bottom that casing open -top is connected with the funnel no. One, and flourishing hydrophone is connected one number to a funnel bottom, and one number flourishing hydrophone bottom is connected with pressure sensor no. One, one number flourishing hydrophone still is connected with no. Two funnels through a siphon, no. Two the funnel is connected with two numbers flourishing hydrophones, two numbers flourishing hydrophone bottom is connected with pressure sensor no. Two, a pressure sensor and no. Two pressure sensor are connected with data collection station through the data line respectively, one number no. Two siphons are still connected as the overflow pipe to flourishing hydrophone. The utility model provides a rainfall monitoring devices, simple structure improves the accuracy to the rainfall monitoring. Needle top structure is adopted on the top, can avoid birds to stop on device instrument top, excretes excrement and urine to influence the accuracy of device.

Description

Rain fall monitor

Technical field

This utility model relates to rainfall monitoring field, particularly for the rain fall monitor of geological disaster.

Background technology

The geological conditions of China some areas is considerably complicated, causes geological disaster often to occur, and locality is caused certain economic loss and personnel's injury.And the generation of geological disaster, directly related with local rainfall.Existing monitoring rainfall instrument is limited by physical features and observation, is substantially not suitable for using on complicated geological conditions.The monitoring rainfall instrument that such as some precision are higher, because structure is the most accurate and complicated, and the external condition in geological disaster region is severe, causes significantly to reduce service life, and is vulnerable to destroy, thus causes the cost monitoring rainfall greatly to increase；And part simple monitoring rainfall instrument is because of the limitation of self instrument, does not reaches the monitoring rainfall precision of requirement, cause basically can not using in severe geological disaster region.

Utility model content

The purpose of this utility model is to provide a kind of simple in construction and the monitoring rainfall instrument that can use under severe geological disaster environment.

This utility model solves the scheme that its technical problem is used:

Rain fall monitor, including pin top, housing, base, described pin top is arranged in case top, base is arranged in housing bottom, case top opening connects a funnel, and a funnel bottom connects a water container, and connecting bottom a water container has a pressure transducer；A number water container connects also by a siphon and No. two funnels；No. two funnels and No. two water containers connect；Connect bottom No. two water containers and have No. two pressure transducers；A number pressure transducer and No. two pressure transducers are connected with data acquisition unit by data wire respectively；A number water container is also connected with No. two siphons as overflow pipe.

Water-proofing treatment is carried out outside data acquisition unit, internal containing sender unit, can be by test remote data transmission, it is not necessary to on-the-spot record data, it is achieved remotely monitor.

The rain fall monitor that this utility model provides, simple in construction, and visual plant is in enclosure interior, is protected by housing, is hardly damaged, and improves the degree of accuracy to rainfall monitoring.Top uses pin roof construction, birds can be avoided to rest on device instrument tip, void excreta, thus affect the degree of accuracy of device, and the lower end of device devises base so that device is built on stilts on the ground, it is to avoid device is damaged by ground birds of looking unfamiliar.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Detailed description of the invention

With specific embodiment, this utility model is described in detail below in conjunction with the accompanying drawings.

As shown in Figure 1, rain fall monitor, including pin top 1, housing 2, base 3, described pin top 1 is arranged in housing 2 top, base 3 is arranged in bottom housing 2, housing 2 open top connects a funnel 4, connects a water container 5 bottom a funnel 4, and connecting bottom a water container 5 has a pressure transducer 7；A number water container 5 is connected with No. two funnels 44 also by a siphon 6；No. two funnels 44 are connected with No. two water containers 55；Connect bottom No. two water containers 55 and have No. two pressure transducers 77；A number pressure transducer 7 and No. two pressure transducers 77 are connected with data acquisition unit by data wire 8 respectively；A number water container 5 is also connected with No. two siphons 66 as overflow pipe.

When rainwater is few, rainwater enters in a water container 5 by a funnel 4, and now a pressure transducer 7 can directly read force value, and by data acquisition unit, the force value of collection is remotely transferred to receptor, further according to specific formula, force value is utilized to extrapolate the number of rainfall.When rainwater is more, No. two funnels 44 are spilt over from a siphon 6, and flow in No. two water containers 55, now No. two pressure transducers 77 also have force value, two force value gathered remotely are transferred to receptor by data acquisition unit, the amount of rainfall that the additive value of both force value goes out according to formula to calculating, it is simply that now rainfall number.When rainwater is the most, rainwater also can be overflowed by No. two siphons 66, speed due to two siphonal drainings is much larger than the speed of rainfall, water in final two water containers still can be discharged, simply the time of draining is longer than not having siphon drainage time during rainfall, according to this rule, utilize existing computing formula can show how many final two rainfall are worth, take the mean and be final rainfall value, accordingly even when rainfall is big again, the error surveyed also can reduce by 50% than existing rain fall monitor.

Below it is only concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.The technical scheme that all employing equivalents or equivalence are replaced and formed, within the scope of all falling within this utility model rights protection.
