Embodiment Construction

[0017] The specific implementation manner of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0018] 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.

[0019] 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), a...

Abstract

The invention discloses a river sediment depth measuring device comprising a pneumatic control circuit and a support guide measurement system. The pneumatic control circuit is composed of a pneumatic motor (1), a manual reversing valve (6) and a compressed air storage tank (7). The support guide measurement system is composed of measuring rods (2), a support guide frame (3), a support guide base (4) and a measuring head (5). The top end of the measuring rods (2) is connected with the power output shaft of the pneumatic motor (1), and the bottom end of the measuring rods (2) is connected with the measuring head (5). During operation, the measuring device is installed on a measuring ship, the pneumatic motor (1) makes the measuring rods (2) and the measuring head (5) rotate and drill in through a transmission thread, and when the measuring head (5) drills into the bed of a river, the direction of rotation of the pneumatic motor (1) is changed by the manual reversing valve, the measuring rods (2) and the measuring head (5) are taken out, and the sediment depth of the river is calculated through sediment observation holes according to the number of the measuring rods (2) used.

Description

technical field [0001] The invention relates to the technical field of river sediment depth measurement, in particular to a river sediment depth measurement device. Background technique [0002] The Yellow River is a sandy river. Sediment deposition is the root cause of flood hazards in the lower reaches of the Yellow River. Regular cleaning of river sediment is an effective way to prevent hazards. The sediment depth is an important data when cleaning the sediment, but there is no effective measuring device at present. [0003] Aiming at the difficult problem of the existing river sediment depth measurement, the present invention designs a river sediment depth measurement device with simple structure and convenient operation, and realizes the purpose of conveniently and quickly measuring the river sediment depth. Contents of the invention [0004] The purpose of the invention is to design a river silt depth measuring device. The device drives the measuring head to drill ...
