Abstract
The utility model discloses a manhole cover alarm comprising a power supply, a pressure switch, an infrared detector and a warning device which are sequentially connected, wherein the pressure switch is disposed at a position, which is in contact with the manhole cover, on the manhole wall, so that the pressure switch is closed when the manhole cover is opened; and the power supply and the warning device are disposed on the manhole wall, and the infrared detector is aslant arranged on the manhole wall so that infrared light emits aslant upward from the infrared detector. The alarm may give a warning at the time when the manhole is lost so that the passing pedestrians are prevented from falling into the manhole, and thus safety is improved.
Description
Technical field
The utility model relates to a kind of alarm structure.
Background technology
Often stolen or damage of well lid on the road at present, owing to well lid is lost the accident that causes casualties and is happened occasionally, although there is the staff warning sign to be set in the position of losing well lid, but the urban size is very big, the staff can't accomplish in the very first time that well lid is lost warning sign to be set, and needs the device that caution is made in a kind of position that can lose well lid immediately badly.
The utility model content
The purpose of this utility model is to provide a kind of well lid alarm, and it can make caution in the very first time that well lid is lost, prevent by way of the pedestrian fall into well, improve security.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of well lid alarm, comprise successively the power supply that connects, press bit switch, infrared eye and warning device, described pressure bit switch to be located on the borehole wall and with the well lid position contacting, press the bit switch closure when well lid is opened; Described power supply and warning device are located at the borehole wall, and infrared eye tilts to be located at the borehole wall, and the infrared ray that infrared eye is sent is tilted to emission.
Above-mentioned warning device comprises hummer and the flashlamp that is connected with infrared eye respectively.
After adopting such scheme, whether the utility model is at first lost by pressing bit switch to embody well lid, when well lid is lost, pressure bit switch closure, power supply is powered to infrared eye, but whether the infrared eye sensing has people's process, and the control warning device sends alerting signal when people's process is arranged, remind the pedestrian to note safe ready.
Description of drawings
Fig. 1 is principle schematic of the present utility model.
Embodiment
Below with reference to accompanying drawing, the technical solution of the utility model and beneficial effect are elaborated.
As shown in Figure 1, the utility model provides a kind of well lid alarm, comprise the power supply, pressure bit switch, infrared eye and the warning device that connect successively, wherein, described pressure bit switch be located on the borehole wall and with the well lid position contacting, under the normal operating position of well lid, press bit switch owing to the pressure of well lid is in off-state, and when well lid is opened, press the bit switch closure; Described power supply and warning device are located at the borehole wall, and can carry out waterproof measure, and infrared eye tilts to be located at the borehole wall, and the infrared ray that infrared eye is sent is tilted to emission.
During use, under the normal operating position of well lid, the pressure bit switch disconnects, infrared eye is not worked, in case and well lid is opened because of stolen or damage, pressure bit switch closure, this moment power supply power to infrared eye, infrared eye is tilted to and sends infrared ray, when nobody through out-of-date, infrared ray does not stop, and as the people through out-of-date, infrared radiation is returned to human body, infrared eye can be controlled warning device and sent alerting signal this moment, remind passer-by to note, thereby avoid the generation of casualty accident.
In order to strengthen the warning effect, warning device can adopt hummer and flashlamp simultaneously, utilizes the form of acousto-optic to report to the police.
Above embodiment only is explanation technological thought of the present utility model; can not limit protection domain of the present utility model with this; every according to the technological thought that the utility model proposes, as to do on the technical scheme basis any change all falls within the utility model protection domain.
