Infrared tube rainfall counter
Technical field
The present invention relates to rainfall counted fields, particularly a kind of rainfall counter tongue tube in existing double skip rainfall inductor and magnet steel part being replaced with infrared tube.
Background technology
Existing double skip rain sensor segment count adopts tongue tube as the sensing device of counter, tongue tube cracky and fault is difficult to investigation, so be in use difficult to judge whether tongue tube normally works.The wire-link telemetry rainfall instrument that skip type rain teleguage is made up of inductor, register etc.Inductor is made up of raingauge receiver, upper tipping bucket, metering tipping bucket, counting tipping bucket, dry reed switch etc.Upper tipping bucket is the precipitation intensity making the precipitation of different natural intensity be adjusted to approximate size, to reduce the amount of rainfall because tipping bucket upset moment receives, because of the randomness that different precipitation intensity is brought.The reason that directly do not count of metering tipping bucket is the impact in order to avoid the electromagnetic field of signal output system measures rainfall.
Double skip inductor is made up of raingauge receiver (diameter is 20cm), upper tipping bucket, lower tipping bucket, collecting funnel, metering tipping bucket, counting tipping bucket, tongue tube etc.The precipitation that raingauge receiver is collected enters upper tipping bucket by funnel, and when rainwater amasss a certain amount of, because the Action of Gravity Field of water own makes upper tipping bucket overturn, water enters collecting funnel.When precipitation injects metering tipping bucket from the choker-line of collecting funnel, just the natural precipitation of varying strength, be adjusted to more uniform precipitation intensity, to reduce the measuring error because precipitation intensity difference causes.When the quantity of precipitation that metering tipping bucket bears is 0.1mm, the metering tipping bucket also had is 0.5mm or 1mm, and metering tipping bucket is poured into precipitation in counting tipping bucket, and counting tipping bucket is overturn once.Metering tipping bucket is when overturning, and to tongue tube surface sweeping once, tongue tube closes once because of magnetization the magnet steel relevant to it instantaneously.Like this, when quantity of precipitation reaches 0.1mm at every turn, just send a switching signal, register or collector just automatically gather and store 0.1mm quantity of precipitation.At present, traditional double skip rain sensor counter block there is device cracky and fault is difficult to investigation, in use cannot judge whether tongue tube normally works, and automatically gathers the problem storing quantity of precipitation weak effect.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of infrared tube rainfall counter, be intended to solve traditional double skip rain sensor counter block and there is device cracky and the very difficult investigation of fault, in use cannot judge whether induction original paper normally works, and automatically gathers the problem storing quantity of precipitation weak effect.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of infrared tube rainfall counter, is connected with funnel, collecting funnel, raingauge receiver and support from the top down in turn; Described raingauge receiver inner bottom is provided with counting tipping bucket, just be provided with metering tipping bucket to above described counting tipping bucket, described raingauge receiver inside is also provided with infrared transmitting tube, and described infrared transmitting tube lower end is connected with infrared receiving tube, and described infrared receiving tube is arranged on metering tipping bucket; Described pedestal lower end is provided with draining valve.
Also screen pack is connected with between described funnel and collecting funnel.
Described infrared transmitting tube adopts 3MM940nm infrared transmitting tube.
Described infrared receiving tube adopts integrated omnipotent infrared receiving tube VS/HX1838/PC638.
Compared with prior art, the invention has the beneficial effects as follows: be provided with infrared transmitting tube, achieve the emission function of signal, instead of tongue tube and magnet steel parts, improve and automatically gather storage quantity of precipitation effect.Be provided with infrared receiving tube, achieve when tipping bucket does not turn over, whether checkout equipment normally works.Tongue tube in existing double skip rainfall inductor and magnet steel part are replaced with infrared tube by infrared tube rainfall counter, whether get final product checkout equipment when tipping bucket does not turn over can be normal, avoid device work cracky, facilitate malfunction elimination, automatically gather storage quantity of precipitation effective.

Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
As shown in Figure 1, a kind of infrared tube rainfall counter provided by the invention mainly comprises: funnel 1, screen pack 2, raingauge receiver 3, collecting funnel 4, infrared transmitting tube 5, infrared receiving tube 6, support 7, metering tipping bucket 8, counting tipping bucket 9 and draining valve 10.Be connected with funnel 1, collecting funnel 4, raingauge receiver 3 and support 7 from the top down in turn; Described raingauge receiver 3 inner bottom is provided with counting tipping bucket 9, just to being provided with metering tipping bucket 8 above described counting tipping bucket 9, described raingauge receiver 3 inside is also provided with infrared transmitting tube 5, described infrared transmitting tube 5 lower end is connected with infrared receiving tube 6, and described infrared receiving tube 6 is arranged on metering tipping bucket 8; Described support 7 lower end is provided with draining valve 10.
Screen pack 2 is also connected with between described funnel 1 and collecting funnel 4.Arranged by this, the impurity in rainwater can be filtered out, avoid the impact that impurity counts this device.
Described infrared transmitting tube 5 adopts 3MM940nm infrared transmitting tube.
Described infrared receiving tube 6 adopts integrated omnipotent infrared receiving tube VS/HX1838/PC638.
During apparatus of the present invention work, rainwater is collected by funnel 1, filters removal of contamination by screen pack 2, is flowed into and be saved in raingauge receiver 3 by collecting funnel 4, and then utilizes metering tipping bucket 8 pairs of rainwater to measure, and utilizes counting tipping bucket 9 to count.Whether can normally work by checkout equipment when metering tipping bucket 8 and counting tipping bucket 9 do not turn over, time tipping bucket does not turn over, infrared receiving tube 6 can receive the signal that infrared transmitting tube 5 is launched, if can not receive, just illustrate that instrument has damage, otherwise instrument normally works.And in the process of tipping bucket upset, infrared receiving tube 6 can not receive signal, time therefore infrared receiving tube 6 does not receive signal, metering tipping bucket 8 just to turn over once.Apparatus of the present invention improve automatically to gather and store quantity of precipitation effect, utilize draining valve 10 storage Water in Rainwater Drainage can be run out.
