The invention relates to the technical field of depth measurement, and discloses a river depth measuring device for land surveying and mapping and a use method thereof, the river depth measuring device comprises a floating plate, the top of the floating plate is provided with a through circular groove, the river depth measuring device also comprises a winding roller, the winding roller is rotatably installed on the top of the floating plate, and a connecting rope is wound on the winding roller; the detection assembly is arranged in the circular groove, and the detection assembly is used for detecting whether the connecting rope is inclined or not; the grounding assembly is arranged below the floating plate, the grounding assembly is further connected with the tail end of the connecting rope, and the grounding assembly is used for detecting whether the grounding assembly reaches the bottom of the river or not; and the correcting assembly is used for correcting the inclined connecting rope. According to the invention, when the depth of the river channel is measured, whether the connecting rope is inclined or not is detected, and the floating plate is automatically driven to move after the inclination of the connecting rope is detected synchronously, so that the connecting rope is vertical, the length reading of the connecting rope is accurate after the cylinder body touches the bottom, and the accuracy of measuring the depth of the river channel is further improved.

    本发明涉及深度测量技术领域,公开了一种土地测绘用河沟深度测量装置及其使用方法,包括浮板,浮板顶部开设有贯穿的圆槽,还包括:绕线辊,绕线辊转动安装于浮板顶部,且绕线辊上绕接有连接绳;检测组件,检测组件设置于圆槽内部,且检测组件用于对连接绳是否歪斜进行检测;触底组件,触底组件设置于浮板下方,且触底组件还与连接绳末端连接,触底组件用于检测是否到达河沟的底部;矫正组件,矫正组件用于矫正歪斜的连接绳。本发明能够在测量河沟深度时,对连接绳是否歪斜进行检测,同步的在检测到连接绳歪斜后自动驱动浮板移动,以实现连接绳垂直,保证了筒体触底后连接绳长度读数准确,进而提高了对河沟深度测量的准确性。
