Abstract
The invention discloses an anti-explosion voice board for coal mines. The anti-explosion speech board comprises an outer frame, wherein a display panel is arranged at one end of the outer frame; a rear housing is arranged at the other end of the outer frame; a hollow cavity is defined by the rear housing and the display panel; a cuboid-shaped component accommodating box is arranged in the hollow cavity; a player connected with a voice microphone is arranged inside the component accommodating box; an electro-luminescent plate covering the display panel is arranged on one side of the player, and is connected with a solar photovoltaic panel arranged at the top of the outer frame; a storage battery is arranged on one side of the solar photovoltaic panel. The anti-explosion voice board can be used in the coal mining field, and information is convenient to disclose on the display panel; solar energy is adopted to save energy sources; workers are enabled to know about the related information in time, so that the safety accidents are avoided; the practicability is high, the expandability is excellent, and the design is novel; the anti-explosion voice board adopts a good innovation scheme, and has a market popularization prospect.
Description
Technical field
The present invention relates to coal mining field, particularly relate to a kind of coal mine explosion-proof voice board.
Background technology
Colliery is the proportional space that the mankind excavate when digging and being rich in the geological stratification of coal, generally includes tunnel, well cave and face etc.Coal is topmost solid fuel, is the one of kaustobilite.It is by the plant in great numbers grown certain geological epoch, in suitable geological environment, is piled into thick-layer gradually, and is buried in the bottom or silt, formed through very long geochronic natural incoalation.In the world in Various Geolcgical Ages, maximum with producing coal in the stratum in the Carboniferous Period, the Permian Period, Jurassic Period and the Tertiary Period, be important coal-forming age.The phosphorus content of coal is generally 46 ~ 97%, in brown to black, has dim to metallic luster.According to the difference of degree of coalification, coal can be divided into peat, brown coal, bituminous coal and anthracite four class.At present, in the process of coal mining, lack relevant safeguard procedures, workman can not be made to understand relevant information in time, cause a lot of security incidents, bring very large threat to life security, there is very large drawback.
In sum, for the defect of prior art, a kind of coal mine explosion-proof voice board of special needs, to solve the deficiencies in the prior art.
Summary of the invention
For the deficiency that coal mining in prior art exists, bring very large drawback to actual employing, the present invention proposes a kind of coal mine explosion-proof voice board, novel in design, timely current events information can be issued, make exploitation workman overall understanding, to address the deficiencies of the prior art.
To achieve these goals, technical scheme of the present invention is as follows:
A kind of coal mine explosion-proof voice board, comprise housing, one end of housing is set to display floater, other one end of housing is set to back cover, the hollow cavity formed between back cover and display floater is set to the element storage case of cuboid, and element storage case inside is provided with the player connecting voice microphone, and the side of player is provided with the electroluminescent sheet covering display floater, electroluminescent sheet connects the solar energy photovoltaic panel that outer arch is placed, and the side of solar energy photovoltaic panel is provided with battery.
The back side of back cover of the present invention is provided with heat elimination hole.
Further, the below of described housing is provided with bracing frame, and bracing frame is A-frame.
The invention has the beneficial effects as follows: this product structure is simple, can be used in above coal mining field, be convenient to various public notification of information face on a display panel, and adopt solar energy, save the energy, workman can the have been made timely information of decorrelation, avoid the generation of security incident, Practical Performance is good, Scalable Performance is excellent, modern design, is a kind of well innovation scheme, has very much marketing prospect.
Accompanying drawing explanation
The present invention is described in detail below in conjunction with the drawings and specific embodiments:
Fig. 1 is structural representation of the present invention.
detailed description of the invention
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the present invention further.
See Fig. 1, a kind of coal mine explosion-proof voice board, comprise housing 100, one end of housing 100 is set to display floater 110, other one end of housing 100 is set to back cover, the hollow cavity formed between back cover and display floater 110 is set to the element storage case 160 of cuboid, element storage case 160 inside is provided with the player 150 connecting voice microphone, the side of player 150 is provided with the electroluminescent sheet 120 covering display floater 110, electroluminescent sheet 120 connects the solar energy photovoltaic panel 130 that housing 100 top is placed, the side of solar energy photovoltaic panel 130 is provided with battery 140.
The back side of back cover of the present invention is provided with heat elimination hole.The below of housing 100 is provided with bracing frame 170, and bracing frame 170 is A-frame.
The present invention is effective is: structure is simple, can be used in above coal mining field, be convenient to various public notification of information face on a display panel, and adopt solar energy, save the energy, workman can the have been made timely information of decorrelation, avoid the generation of security incident, Practical Performance is good, Scalable Performance is excellent, modern design, is a kind of well innovation scheme, has very much marketing prospect.
The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and manual just illustrates principle of the present invention; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
