Abstract
The utility model relates to a multifunctional safety helmet. The multifunctional safety helmet comprises a safety helmet shell body and a buffer support which is located on the inner side of the shell body. A buffer block is arranged between the shell body and the buffer support. One end of the buffer block is fixed on the buffer support, a lamp seat is arranged on the outer side of the upper front portion of the safety helmet shell body, and a voice device is arranged on the rear portion of the lamp seat. The multifunctional safety helmet is characterized in that at least one small hole is formed in the upper rear portion of the safety helmet shell body, a layer of nanofiltration membrane is fixed on the upper rear portion of the inner side of the safety helmet shell body, and the nanofiltration membrane is made of polyamide. The voice device comprises a signal receiver, a processing unit which is connected with the signal receiver, and a loud speaker which is connected with the processing unit, wherein the loud speaker is a paper horn. The multifunctional safety helmet is simple in structure, and convenient to implement. The layer of nanofiltration membrane is arranged on the upper rear portion of the inner portion of the safety helmet shell body, and at the same time the small hole is formed in the upper rear portion of the safety helmet shell body, water flows out through the small hole to be directly used as drinking water. The paper horn is adopted in the voice device as a sound producing device. The multifunctional safety helmet has the advantages of being simple in structure, light in weight and the like, and further has the advantages of being low in working current and working voltage, low in relative overall power consumption and the like.
Description
Technical field
The utility model relates to the coal mine protective apparatus, is specifically related to a kind of multifunctional safety helmet.
Background technology
Along with the development of society, no matter the progress of science and technology is industrial production or daily life, and the demand of electric power is more and more relied on for counsel, and industrial production is also increasing to the demand of coal.At present; still a large amount of dependence manpower exploitation on the colliery; in the coal mining process to staff's protection; become the most important thing of work; safety cap particularly; application number is that 201120547106.5 patent has been announced a kind of Multifunctional mining safety helmet; this patent has solved the problem of generating electricity from manpower illumination; but do not solve drinking-water and the problem of communicating by letter; application number is 201120488266.7 patent; announce a kind of safety cap with sound prompt function, solved work safety and pointed out this problem, also do not solved communication and Drinking Water Problem.
Summary of the invention
The utility model proposes a kind of multifunctional safety helmet for the problem that prior art exists.
The technical solution of the utility model is: a kind of multifunctional safety helmet, comprise helmet shell and the buffering stand that is positioned at the housing inboard, be provided with buffer stopper between housing and the buffering stand, one end of buffer stopper is fixed on the buffering stand, arranged outside in the helmet shell front upper place has lamp socket, the lamp socket rear is provided with voice device, and the back upper place of helmet shell is provided with an aperture at least, and the inboard back upper place of helmet shell is fixed with one deck NF membrane.
Described multifunctional safety helmet, the material of NF membrane are the polyamide material.
Described multifunctional safety helmet, voice device comprises signal receiver, the processing unit that is connected with signalling means, and the loudspeaker that is connected with processor.
Described multifunctional safety helmet, described loudspeaker are the paper loudspeaker.
The beneficial effects of the utility model: 1. the utility model is simple in structure, and it is convenient to implement, and in the back upper place of helmet shell inside one deck NF membrane is set, and offers aperture at the housing of helmet shell back upper place simultaneously; Safety cap is as the utensil that is filled with water, fill water after, water is through the filtration of NF membrane, water flows out directly as drinking-water with drinking by aperture;
2. voice device of the present utility model adopts the paper loudspeaker as acoustical generator, and constituting by two pieces of paper of paper loudspeaker spreads with metallic film in the above and work as electrode, and sandwiches the vibrating membrane formation of one deck static electrification lotus in the centre, have simple in structure, the advantage such as quality is light; Also have operating voltage in addition, electric current is little, relatively overall power is low, therefore can save electricity consumption, lengthens working hours.
3. apopore design of the present utility model avoids the apopore design in roof fall in the back side top of helmet shell like this, and when purifying waste water, water can be dipped into the voice device that is positioned at the lamp socket rear.
