A river sediment depth measuring device according to the present invention comprises that the air motor (1) is fixed on the upper surface of the supporting guide frame (3) through screw connection; the thick end (larger diameter) of the measuring rod (2) is inserted into the air Inside the power output shaft of the motor (1), the position is fixed and locked by the lock nut (14); the thin end (smaller diameter) of the measuring rod (2) is inserted into the measuring head (5), and the axial relative position is controlled by the positioning boss (23) is determined, and the radial relative position is determined by the positioning groove (25) and the positioning boss (23).

The technical solution of the present invention is: take out the measuring rod (2) and the measuring head (5) after the downward drilling of the measuring head is completed, and calculate the sediment depth of the river through the sediment observation hole of the measuring rod (2), wherein, The lengths of the measuring head (5) and the measuring rod (2) are both 1000mm, and there are many sediment observation holes on the measuring head (5) and the measuring rod (2), and the observation holes are arranged in a linear arrangement; the measuring head (5), measuring The distance between the sediment observation holes on the pole (2) is 100mm; the serial number of the measuring pole (2) connected with the measuring head (5) is stipulated as 2, and the measuring pole (2) connected with the No. 2 measuring pole (2) The sequence number is 3, and the numbering of other measuring rods (2) is deduced by analogy.

Assuming that the result of a measurement is that the sediment is first seen in the Mth sediment observation hole of the measuring rod with the serial number N, then the sediment depth L of the river is:

L=(N-1)×1000+M×100 (unit: mm).

detailed description

The specific implementation manner of the present invention will be described in further detail below in conjunction with the accompanying drawings.

First, install the sediment depth measurement device on the survey boat, and start the measurement work when it arrives at the water area to be measured.

The method of increasing the measuring rod: when the air motor drives the measuring rod (2) to move to the bottom of the support-guided measuring system, move the manual reversing valve (6) to the neutral position, the air motor stops rotating, open the lock nut (14) and turn the Lift the support guide frame (3) to the highest point, fix the position of the support guide frame (3) with the lock nut (44), connect the bottom end of the newly added measuring rod (2) to the top of the original measuring rod (2) After the connection is locked with the nut, open the lock nut (44), drop the support guide frame down to a proper position, lock the lock nut (14), and move the manual reversing valve (6) to the upper position to continue Measure jobs, and so on.

How to take out the measuring rod: When the air motor (1) drives the measuring rod (2) to move to the top of the support-guided measuring system, move the manual reversing valve (6) to the neutral position, the air motor (1) stops rotating, and lock the nut (14) After opening, raise the support guide frame (3) to the highest position, fix the position of the support guide frame (3) with the lock nut (44), and fix the lock nut at the bottom end of the measuring rod (2) that needs to be taken out After opening, take out the measuring rod (2), open the lock nut (44), drop the supporting guide frame to the appropriate position, lock the lock nut (14), and move the manual reversing valve (6) Continue the measurement operation to the next position, and so on.
