Road depth of accumulated water sensor
Technical field
The utility model relates to road depth of accumulated water sensing technology.
Background technology
Be positioned at road that depression, culvert etc. locate under given conditions (for example heavy rain, typhoon etc.) may produce serious ponding, vehicle, pedestrian still can pass through when depth of accumulated water is more shallow; When depth of accumulated water is dark, then all be difficult to pass through; And if vehicle, pedestrian unfortunately are trapped in this highway section when depth of accumulated water is too dark, what for to causing catastrophic failure.So in order to ensure current safety, the ponding for road occurs should arrange level detecting device, the real-time detection water level, and take different measures according to different water levels.
Existing level sensor technology, though also can be used for surveying the road depth of accumulated water, owing to be not custom-designed for this reason, seem that some is not too convenient, perhaps cost is higher, and difficulty, the undesired signal that occurs in the time of perhaps can not effectively shielding extra torrential rain perhaps are installed.
For example, adopt the water-level measuring post of a plurality of electrode structures, its principle is with a plurality of arrangement of electrodes position at various height, because surface water all conducts electricity, electrode does not just form between the electrode that then is submerged and conducts (resistance is very little) in case by water logging, then can not form between the electrode that is not had by water logging to conduct that (resistance is very big, be infinitely great in theory), can detect different water levels according to the situation of conducting of different electrodes.For this water-level measuring post, if the intensity of rainfall is too big, electrode surface just may form thicker moisture film, material surface between the electrode also may form thicker moisture film, the moisture film on different materials surface is connected mutually, and because moisture film conducts electricity, this just makes to form between each electrode and conducts.Because each electrode was formed by moisture film and conducted this moment, rather than was not had formation to conduct by water logging, so its water level that detects can not reflect real water level, namely formed wrong report.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of road depth of accumulated water sensor that is fit to be installed on the road for detection of the road depth of accumulated water is provided, this sensor can be exported 3 water level signal, and stable output signal, even also can not be affected at extra torrential rain weather.

In above-mentioned each technical scheme, all tongue tubes in described low-water level tongue tube, middle water level tongue tube and the high water stage tongue tube all available Hall element are replaced.
After having adopted technique scheme, the utlity model has following beneficial effect:
1. can detect the road depth of accumulated water, and with the occasion of depth of accumulated water electricity consumption the signal is far passed to needs, wherein can detected lowest water level value, middle water level value and peak level value can be adjusted by the quality size of adjusting corresponding water level balancing weight, so sensor is relatively good to the adaptability of the water level range of require detection.
2. the error of water level detecting is little, the reasons are as follows:
When a. water level was low, the ponding on the road surface can enter the below of fexible film by the groove on the road surface, and film is applied a thrust that makes progress, and the size of thrust just is proportional to the degree of depth of ponding; Because flexible partition is substantially zero in the rigidity of distortion starting stage, so, when depth of accumulated water rises to when enough high, it is enough big that described thrust will reach, be enough to the low-water level balancing weight is risen to enough height, make the magnet that is arranged on the interior ring of the backing plate muscle rise to the height that the low-water level tongue tube is connected, the lowest water level value that this can detect highly exactly; Obviously, the detected lowest water level value of energy just depends on the mass value of low-water level balancing weight, and the error of the detected lowest water level value of energy also just depends primarily on the mass value error of low-water level balancing weight;
B. the continuation along with the surface gathered water degree of depth increases, and the ponding on the road surface can continue to enter by the groove on the road surface below of fexible film, and film is applied a thrust that makes progress, and the size of thrust still is proportional to the degree of depth of ponding; Its rigidity is very little basically close to zero when flexible partition is provided with the U-shaped ripple, so, when depth of accumulated water rises to when enough high, described thrust will overcome mainly be each corresponding water level balancing weight close that gravity that quality produces and the gas in the described inner chamber are compressed and the bounce that produces; Because the volume for this inner chamber of approved product is a definite value basically, error is very little, so the error of the detected water level value of energy (middle water level or high water stage) also just depends primarily on the error of closing mass value of each corresponding water level balancing weight;
C. because the error of part quality value control error control with respect to the spring rate value when manufacturing is much easier, so the error of the utility model sensor water level detecting is little.
3. because of the corresponding certain hydraulic pressure of certain depth of accumulated water, what in fact sensor detected is hydraulic pressure, so, can not be subjected to the influence of ponding water quality during operation, also can not be subjected to the influence of rainfall intensity, stable, signal output is reliable.
4. be provided with anchor (bolt) hole, can install and fix on the ground easily.
