The invention provides a rain and snow prevention ultrasonic sensor rotating mechanism, and belongs to the technical field of environmental perception. The mechanism comprises a sealed cabin, a stepping motor, a connecting mechanism, a rotary supporting frame and a sensor fixing device. The sealed cabin is installed on the snow pressing vehicle body, the stepping motor is installed in the sealed cabin, the sensor fixing device is fixed to the rotary supporting frame through a rolling bearing, and the stepping motor and the sensor fixing device are connected through a coupler. At present, no ultrasonic rotating distance measuring mechanism suitable for the snow pressing vehicle at the outdoor temperature below zero exists in the market, and the ultrasonic rotating distance measuring mechanism can achieve 360-degree rotation of the ultrasonic transducer. Operators complete detection processes in different ranges by adjusting the working state of the stepping motor without installing a plurality of sensors, so that the cost of the detection system is greatly reduced. According to the mechanism, the efficiency of an ultrasonic detection system is greatly improved, and a foundation is laid for application in a rainfall and snowfall operation environment in winter.
本发明提供一种防雨雪超声传感器旋转机构,属于环境感知技术领域。该机构包括密封舱、步进电机、连接机构、旋转支撑架和传感器固定装置。密封舱安装于压雪车身上,步进电机安装在密封舱内,传感器固定装置通过滚动轴承固定在旋转支撑架上,通过联轴器连接步进电机和传感器固定装置。目前市场上未存在适用于室外零下温度的压雪车用超声波旋转测距机构,本发明可以实现超声波换能器360°旋转。操作人员通过调整步进电机的工作状态完成不同范围的探测过程,无需安装多个传感器,大大降低了探测系统的成本。本机构极大的提高了超声探测系统的效率,为冬季降雨降雪作业环境中的应用奠定了基础。
