Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 depicts the top view of a kind of simple and easy rain detecting sensor described in the present embodiment.
Fig. 2 depicts the front view of a kind of simple and easy rain detecting sensor described in the present embodiment.
Fig. 3 depicts the decomposing schematic representation of a kind of simple and easy rain detecting sensor described in the present embodiment.
Detailed description of the invention
Refer to Fig. 1, Fig. 2 and Fig. 3, a kind of simple and easy rain detecting sensor, it include an insulation board 1, two pairs with the use of stainless steel bolt 2 and nut 3, two conducting strip 4.
Spaced apart two attachment hole 11 that are provided with on insulation board 1, insulation board 1 is installed on open air in angled downward from horizontal, and when insulation board 1 is installed in angled downward from horizontal time, two attachment hole 11 are positioned in same level；Two conducting strips 4 are respectively through the bolt 2 cooperated for a pair and fixing attachment hole 11 place being crimped on two correspondences of nut 3.
The constant spacing of described conducting strip 4 takes 0.5-5mm, described two attachment hole 11 are horizontally extending long lumbar hole, and the convenient constant spacing regulated between two conducting strips 4, according to required accuracy of detection, if light rain begins to detection, constant spacing is to little range regulation；If heavy rain just needs detection, constant spacing is to big range regulation.
In the present embodiment, described insulation board 1 adopts epoxy resin board.Insulation board 1 is further opened with the installing hole 12 for fixedly mounting this insulation board.The mounting inclination angle degree of insulation board 1 takes 5-45 degree or can take the angle of inclination equal with local latitude according to installing local latitude.
In order to avoid being subject to the erosion of rainwater without the conducting strip 4 of insulation protection; preferably set up two stainless pads 5; this two pad 5 matches fixing attachment hole 11 place being crimped on two correspondences of nut 3 respectively through bolt 2; conducting strip 4 is crimped between bolt 2 and pad 5; thus avoiding conducting strip 4 get rusty due to rain erosion or produce Aerugo; the resistance making conducting strip 4 self is gradually increased after long-term use, finally affects Detection results.And pad 5, bolt 2 and nut 3 all adopt stainless material, the better performances of its tolerance rain erosion, improve the service life of rain detecting sensor.
Preferably, described conducting strip 4 is pre insulated terminal, and this pre insulated terminal band has the extraction wire 6 for measuring.This extraction wire 6 surface has wrapped insulating barrier.
The operation principle of the simple and easy rain detecting sensor described in the present embodiment is as follows: tilt to be mounted on outdoor by installing hole 12 by insulation board 1, matching with two bolts 2 and nut 3 respectively to use apart is arranged in the attachment hole 11 of insulation board 1 by two stainless pads 5 and the two pre insulated terminals with drawing wire, pre insulated terminal compression joint is between bolt 2 (specifically the bolt head of bolt) and pad 5, when fine day or cloudy day do not rain, resistance between two pre insulated terminals is infinitely great, when rainy, rainwater falls when two on the insulation board 1 between pad 5 and two pads 5 installed, resistance between two pre insulated terminals is tens K to the hundreds of K (differences of rainwater composition, the conductivity of rainwater is different, this value can difference to some extent), when raining continuously, resistance between two pre insulated terminals can be always held at tens K to hundreds of K, owing to being insulation board 1 inclination installation, when after rain stops, rainwater between two pads 5 apart will flow down automatically, resistance between two pre insulated terminals slowly can become infinity from hundreds of K again, the change of the resistance between this two pre insulateds terminal can pass through its with extraction wire 6 measure obtain, can be thus that the data volume change that a conventional electronic circuitry can receive is measured the change transitions of " raining " and " not raining " this naturalness.
Rain detecting sensor simple in construction described in the utility model, low cost of manufacture, and reliability are better, and being of value in automatic control system needs installing and using of detection " rainy state ".
The above, be only this utility model preferred embodiment, therefore can not limit the scope that this utility model is implemented according to this, and the equivalence namely made according to this utility model the scope of the claims and description changes and modifies, and all should still belong in the scope that this utility model is contained.
