Description
Technical field
the utility model relates to a kind of speech amplifier, especially relates to a kind of waterproof early warning speech amplifier.
Background technology
in recent years, due to the combined influence of mankind's activity and natural cause, global climate is in warming trend year by year, irregular anomalous weather continues to bring out on a large scale, Extreme Weather Events frequently occurs, bring significant impact and destruction to socio-economic development, people life property safety, the biological environment also making the mankind depend on for existence suffers direct threat.Holding of " Copenhagen World Climate Conference ", confirms that national governments and international body all pay much attention to this, and reply complexity, changeable climate environment have become the important topic concerning the mankind, concern the world.
china is vast in territory, physical features is complicated, monsoon climate is obvious, the disaster that Extreme Weather-climate Events causes is relatively frequent, heavy rain, flood, arid, damage to plants caused by sudden drop in temperature, freeze injury, cold damage, severe snow, hail, dense fog, thunderclaps, spout, strong wind, heat wave, sandstorm, hot dry wind, cloudy weather for several days running, the meteorological disaster such as tropical cyclone happen occasionally.Especially in recent years; it is extreme that weather often there will be climate warming etc.; meteorological disaster presents the feature that kind is many, scope is wide, intensity is large; the loss that meteorological disaster causes every year accounts for about 70% of whole natural calamity; the direct economic loss caused accounts for about the 3-6% of GDP; utilize technological means to prevent and reduce natural disasters, become the important administration content of governments at all levels, water conservancy bureau, Meteorological Unit, Radio & Television Bureau, able to resisting flood and drought office etc.
along with rural economic development and life of farmers level improve, agricultural, rural area, the demand of peasant to weather information particularly diastrous weather information sharply strengthen, but still aobvious single for the weather monitoring means of rural area and peasant, affect carrying out of rural area disaster prevention and relief work to a great extent.Construction of rural meteorological disaster early warning broadcast platform, installing weather warning LED display and meteorological calamity emergency broadcast system, is the infrastructure construction of reinforced region disaster prevention and relief, effectively improves the important channel of meteorological disaster pre-alerting ability.To rural area, " typhon " is the most universal, most convenient, most economical, coverage rate is the widest, the pattern of " meteorological disaster early warning broadcasting receiver+typhon+display screen ", thoroughly solve the problem of weather information to rural area " last one kilometer ", greatly can improve the ability that peasant prevents and reduces natural disasters, bring huge agricultural performance.At present, the early warning speech amplifier on market is functional single, can not meet the need of market.
Utility model content
the purpose of this utility model is to provide one, and to have structure simple, reliable operation, and easy to operate, operating efficiency is high, can play by complete independently, can remote control, saves a kind of waterproof early warning speech amplifier of the advantage such as the energy, environmental protection.
in order to realize the purpose of this utility model, the utility model is achieved through the following technical solutions: a kind of waterproof early warning speech amplifier, comprises vertical rod, early warning speech amplifier, splash guard, megaphone; It is characterized in that: described vertical rod top is provided with splash guard, in the middle of vertical rod, be provided with early warning speech amplifier; Describedly between splash guard and early warning speech amplifier, be provided with megaphone; Described early warning speech amplifier connects megaphone.
operation principle: utilize mains-supplied to early warning speech amplifier, the splash guard at Li Gang top can effectively prevent water from flowing in early warning speech amplifier, is applicable to open air, high-frequency plays early warning, increases service life of equipment.
waterproof early warning speech amplifier of the present utility model has reliable operation, and the advantages such as easy to operate, operating efficiency is high, long service life, and stability is strong, have very high practical value.
