The invention relates to the technical field of thread machining, and discloses a pedestrian crossing signal lamp capable of autonomously cleaning and radiating, which comprises a lamp box, a ventilation opening is formed in the lamp box, a radiating device is arranged in the ventilation opening, a first rack is fixedly connected to the left side of a connecting piece, and a first gear is engagedto the left side of the first rack; a mounting piece is fixedly mounted on the front side of the first gear through a fixing piece; the lower end of the first rack is fixedly connected with a connecting rod, the lower end of the connecting rod is movably connected with a connecting block, and the lower end of the connecting block is fixedly provided with a spring mechanism. A connecting block is driven to move downwards through downward pressing of a protruding block by passing pedestrians or vehicles, a connecting rod fixedly connected with the connecting block moves downwards synchronously,a first rack is fixedly installed at the upper end of the connecting rod and drives a first gear meshed with the first rack to rotate, and a cleaning scraping strip installed on the front side is driven to do fan-shaped motion while the first gear rotates; therefore, the effect of automatically cleaning the light-emitting unit is achieved.
本发明涉及螺纹加工技术领域,且公开了一种可自主进行清洁散热的人行横道信号灯,包括灯箱,灯箱内部开设有通风口,通风口内部设置有散热装置,连接件左侧固定连接有第一齿条,第一齿条左侧啮合有第一齿轮,第一齿轮前侧通过固定件固定安装有安装件,第一齿条下端固定连接有连杆,连杆的下端活动连接有连接块,连接块的下端固定安装有弹簧机构。通过过往行人或车辆将凸块的下压带动连接块的向下位移,与连接块固定连接的连杆同步向下移动,连杆上端固定安装有第一齿条,第一齿条带动与其啮合的第一齿轮进行旋转,第一齿轮旋转的同时带动前侧安装的清洁刮条做扇形运动,从而达到了自主清洁发光单元的效果。
