Description
Technical field
The utility model relates to a kind of safety cap, relates to especially that a kind of a situation arises has down the safety cap of warning function in security incident.
Background technology
Along with the raising of people's living standard, living conditions constantly improve, and the construction site is also more and more.The construction area in most of construction sites is bigger, and building mostly is skyscraper again.In building engineering construction, construction safety is the first, and the construction safety problem can be a long-standing problem, and the object impact is again one of topmost three big security incidents in the construction, and safety cap has been brought into play important effect in safety precaution.Chinese patent Granted publication CN200983873Y, December 5 2007 Granted publication date, the utility model patent that name is called " safety cap that voice have warning function " discloses a kind of safety cap, comprise hemispheric cap body and the shade that fuses with the cap body, be provided with the audio alert integrated circuit in the cap body, this integrated circuit links to each other with switch on being arranged on shade, simultaneously, is connected with loudspeaker on being arranged on the cap body by drive circuit.When these voice have the safety cap use of warning function, whenever pinch shade one time, then report a caveat to carry out phonetic warning to the user, this safety cap has played the safety education effect, improves user's awareness of safety.But, if in a single day the workmen is knocked down by alluvium, there are not other staff to see again, just can not in time be found, incured loss through delay the quality time of rescuing life.In addition, be under the environment of causing danger, can't in time report to the police and delay the time of rescuing as the workmen.
Summary of the invention
Have only the workmen is played protection alluvium effect and do not have the workmen to go down or be in the technical problem that the environment of causing danger is in time reported to the police down in order to solve safety cap, the utility model provides a kind of safety cap with warning function, can send the warning distress signal in case reach automatically after alluvium is knocked down the workmen; Can in time send an SOS when the workmen is absorbed in the environment of causing danger, reduce the purpose of building engineering construction casualties.
The technical solution of the utility model is: a kind of safety cap with warning function, it comprises the cap shell of the hemispherical cavity body structure of safety cap, the hat lining that is connected with cap shell inwall and the brim of a hat that is connected with cap shell opener end, the upper end that is positioned at hat lining at cap shell inner chamber is provided with pressure sensor, the madial wall that is positioned at the cap shell in cap shell and the brim of a hat connection is provided with circuit board, end face at the circuit board of cap shell opener one end is provided with button, circuit board comprises amplifying circuit, control circuit, digital encoder, the input of amplifying circuit is connected with pressure sensor, the output of amplifying circuit is connected with the input of digital encoder by control circuit, and the output of digital encoder is connected with transmitter.When alluvium strike safety cap, the cap shell has distortion slightly, and pressure sensor receives the signal that is under pressure and hits.Pressure sensor is passed to amplifying circuit on the circuit board with signal, and amplifying circuit is connected control circuit, pressure sensor signal input digit encoder.The signal of handling through digital encoder is transmitted into the receiver that is arranged on the Safety Management place by transmitter, and rescuer begins to go to the spot to rescue immediately.When alluvium is not to hit safety cap but other positions of workmen and cause injury to workmen's health, perhaps the workmen enters the deathtrap and oneself can not escape this deathtrap because of carelessness, the workmen presses the button, receiver to the Safety Management place sends an SOS, and rescuer receives that distress signal begins to go to the spot to rescue immediately.Safety cap with warning function not only can play the effect that the protection alluvium hits, and, when being knocked down by alluvium, the workmen can send an SOS automatically, perhaps when the workmen be in hazardous environment and situation about can not save oneself under, can send an SOS and in time be rescued, guarantee workmen's safety.
