Disclosed is a double-pipe propeller of double-pipe power-driven ship for a general survey of an underground drainage culvert. The propeller comprises two cylindrical hollow pipes which are arranged side by side, a motor A is arranged at one ends of the two cylindrical hollow pipes, a motor B is arranged at the other ends of the cylindrical hollow pipes, and main shafts of the motor A and the motor B are coaxial with the cylindrical hollow pipes. The main shafts of the motor A at the end parts of the two cylindrical hollow pipes are respectively connected with forward and reverse propellers, and the main shafts of the motor B are connected with linear blades; the propeller is stable in advancing direction, sufficient in power, small in size, flexible in turning, suitable for a narrow space of the culvert and capable of working in a severe environment with many sundries on the water surface, an effective method is provided for detection through shipborne equipment under the working condition that the water level of the drainage culvert is high, and the technical problem of underground drainage culvert detection is solved.

    本发明公开了一种地下排水涵洞普查的双管式动力船的双管式推进器,包括并排设置的两个柱形空心管,两个柱形空心管一端设置有马达A,柱形空心管另一端设置有马达B,马达A和马达B的主轴与柱形空心管同轴,两个柱形空心管端部的马达A的主轴上分别连接有正反螺旋桨,马达B的主轴上连接有一字型刀片;本发明的推进器行进方向稳定、动力十足、体积小、转弯灵活,适宜在涵洞狭小空间,可在水面有很多杂物的恶劣环境工作,在排水涵洞水位较高的工况下通过船载设备检测提供了一种有效的方法,解决了地下排水涵洞检测技术难题。
