Abstract
The utility model relates to a blind guide rod for preventing a blind person from stepping into a water pit; a circuit which is arranged in the blind guide rod (2) and is connected by a lead (4) internally at least comprises an alarm device (1) and a battery (3) which are connected with in series, and is characterized in that the circuit is also provided with a pair of conductors (5) which is arranged by the lead (4), has interval (L) and is taken as a switch; the pair of conductors (5) is arranged at the bottom end of the blind guide rod (2) which is open at the lower part; and furthermore, a distance (D) is formed between the lower ends of the conductors (5) and the bottom end of the blind guide rod (2). As the pair of conductors (5) with the interval (L) is installed at the bottom end of the blind guide rod (2) which is open at the lower part, the conductors (5) are contacted with the water when the blind guide rod (2) extends into the water pit, a condition is created for electric conduction between the conductors (5), the alarm device (1) gives an alarm, and the aim of reminding the blind person to stop in front of the water pit can be achieved.
Description
Technical field:
The present invention relates to a kind ofly can prevent the enter into blind guiding bar technology in puddle of blind person.
Background technology:
Blind guiding bar does not in the market have reminds the blind person that the place ahead is the function in puddle, and the road surface of just having rained is easy to stay hydrops, some old roads especially, and recess hydrops can form the puddle.The puddle of will entering into because of carelessness during blind person's walking along the street, the shoes of getting wet.
Summary of the invention:
The present invention's purpose: propose a kind of device that addresses the above problem.
For realizing the present invention, intend adopting following technology:
At least comprise in the circuit that blind guiding bar inside is connected by lead: alarm reaches and the alarm series connected battery, it is characterized in that: also in foregoing circuit, have pair of conductors spacing and that use as switch by lead being provided with, this pair of conductors is arranged on the bottom of the blind guiding bar of lower open, and the lower end of this pair of conductors and the bottom of blind guiding bar form spacing distance.
The present invention's characteristics compared with the prior art:
Because the pair of conductors that will have a spacing has been installed in the blind guiding bar bottom of lower open, when blind guiding bar extend into the puddle, conductor touches water, and this is just for conducting electricity the condition created, alarm equipment alarm between the above-mentioned pair of conductors.---realized reminding the purpose that the puddle is arranged before blind person's foot.
Description of drawings:
Figure has illustrated version of the present invention.
1: alarm; 2: blind guiding bar; 3: battery; 4: lead; 5: conductor; L: spacing; D: the distance of conductor lower end and blind guiding bar bottom.
The specific embodiment:
As shown in the figure: (for example: 5 millimeters) pair of conductors 5 is installed in the bottom position of the blind guiding bar 2 of lower open, and the lower end of conductor 5 and blind guiding bar 2 bottoms form distance D (for example: 3 millimeters) with spacing L.
Connect alarm 1, conductor 5 and battery 3 by lead 4, they all are installed in the inside of blind guiding bar 2.Alarm 1 (being generally vibrator or speaker) is installed in the top (allow the blind person feel easily or hear) of blind guiding bar 2.
Because the bottom of blind guiding bar 2 is opened wide, like this, in case the bottom of blind guiding bar 2 touches water, this just means that the pair of conductors 5 that is exposed to the bottom probably contacts with water, alarm 1 is promptly reported to the police, and the blind person knows before the foot at once water, and then has prevented the blind person puddle of entering into.
If the hydrops on ground is very shallow,, just mean that ground water mark can not make above-mentioned pair of conductors 5 form conduction state (can not report to the police), illustrates that this water mark can not form harm to the blind person less than above-mentioned distance D (for example :) less than 3 millimeters.
Claims (1)
1. one kind prevents the enter into blind guiding bar in puddle of blind person, at least comprise in the inner circuit that is connected by lead (4) of blind guiding bar (2): alarm (1) reaches and alarm (1) series connected battery (3), it is characterized in that: also in foregoing circuit, be provided with the pair of conductors (5) (L) and that use as switch that has spacing by lead (4), this pair of conductors (5) is arranged on the bottom of the blind guiding bar (2) of lower open, and the bottom of lower end of this pair of conductors (5) and blind guiding bar (2) forms distance (D).
