Device for detecting scour pit by using sonar
The scour pit detection device using the sonar comprises a base, an adjusting mechanism and a sonar detection assembly, a supporting column is arranged at the upper end of the base, sound wave receivers are evenly arranged on the outer side of the supporting column, the sonar detection assembly comprises a second driving motor and a single-beam sonar depth finder, and the second driving motor and the single-beam sonar depth finder are arranged in a second protective cover. A driven chain wheel is arranged on the outer side of the movable shaft, and the driving chain wheel is connected with the driven chain wheel through a chain. The beneficial effects of the invention are that sound waves are transmitted through a water body to reach the base surface and then are reflected, and the scour depth at a monitoring position is calculated according to the transmission speed and echo time of the sound waves. The single-beam sonar depth finder method has the advantages of being low in equipment cost, high in precision, good in operability, convenient to dynamically monitor the punching pit change process and the like, meanwhile, the angles of the X axis and the Y axis of the single-beam sonar depth finder can be adjusted through the adjusting mechanism, and all-directional detection can be achieved.
一种应用声呐对冲刷坑探测装置，包括底座、调整机构和声呐探测组件，所述的底座的上端设有支撑柱，所述的支撑柱的外侧均匀的设有声波接收器，所述的声呐探测组件包括设置在防护罩二内的驱动电机二和单波束声呐测深仪，所述的活动轴的外侧设有从动链轮，所述的主动链轮和从动链轮链条连接。本发明的有益效果为：本发明通过声波经过水体的传播到达底座面后反射，根据声波的传播速度和回波时间来计算监测位置处的冲刷深度。单波束声呐测深仪方法具有设备成本低、精度较高、可操作性好、对冲坑变化过程动态监测方便等优点，同时可通过调整机构调节单波束声呐测深仪的X轴和Y轴的角度，可实现全方位的探测。
