Double-pipe propeller of double-pipe power-driven ship for general survey of underground drainage culvert

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of detection of underground drainage culverts, and relates to a double-pipe propeller of a double-pipe power ship for general inspection of underground drainage culverts. Background technique [0002] At present, there are many problems in the urban drainage pipe network. For example, the rainwater pipe network often has sewage outlets, and the sewage is discharged into the rainwater pipes, causing the sewage to be directly discharged into the river without going through the sewage treatment plant, causing serious pollution of the river water and threatening human health. Many cities need to be treated. It is necessary to find the location of the sewage outlet in the rainwater culvert, and then take measures such as rain and sewage diversion, so as to achieve the purpose of purifying the water quality of the river. After technological development in recent years, there are many methods for pipe and culvert s...
