The invention discloses an annunciator for road traffic control. The device comprises a box body and electronic elements installed in the box body. Vent holes are formed in two side walls of the box body. A heat dissipation mechanism is arranged in the box body. The heat dissipation mechanism comprises a T-shaped pipe, a driving mechanism used for driving the T-shaped pipe to rotate at a variablespeed, a heat dissipation pipe and a heat dissipation fan. The device further comprises a protection mechanism. The protection mechanism comprises a rain collection box, a pull rope and a protection cover. The device is provided with a heat dissipation mechanism. The T-shaped pipe drives the heat dissipation pipe to rotate at a variable speed, and the angle of the heat dissipation pipe is continuously changed under the condition that centrifugal force is continuously changed, so that the air blowing heat dissipation angle of a nozzle is continuously changed, and heat dissipation is more sufficient and uniform. A protection mechanism is arranged, so that rainwater cannot enter the box body through the heat dissipation holes to wet the electronic elements. When a fire breaks out in the box body, the interior of the whole box body is in a closed oxygen-deficient state, and larger accidents caused by fire spreading are avoided.
本发明公开了一种道路交通控制用信号机,包括箱体以及安装于箱体内的电子元件,所述箱体两侧壁上均设有通风孔,所述箱体内设有散热机构,所述散热机构包括T型管、用于驱动T型管变速转动的驱动机构、散热管和散热风机,还包括有防护机构,所述防护机构包括集雨盒、拉绳和防护罩,本申请设有散热机构,T型管变速带动散热管变速转动,在离心力不断变化的情况下,所述散热管的角度不断发生变化,从而使得喷嘴的吹气散热角度不断变化,散热更加充分、均匀;设有防护机构,使雨水无法通孔散热孔进入箱体内打湿电子元件,当箱体内起火时,使得整个箱体内处于封闭缺氧的状态,避免了火势蔓延造成更大的事故。
