Abstract

The invention discloses a carrying device for an underwater sediment layer surface detection instrument. The device comprises a traction rope, a carrier and a counterweight device. The carrier comprises a cylinder, a cone and a hanging ring which are integrally formed from bottom to top. The traction rope is bound to the hanging ring, containing cavities used for containing the detection instrument are longitudinally formed in the cylinder and the cone in a hollowed-out mode, a side wall of the cylinder and the side wall of the cone are filled with lead and sealed, a screw hole is formed in the side wall of the cylinder in a penetrating mode, and a bolt used for fixing the detection instrument is arranged in the screw hole in a matched mode. The manufacturing method of the carrying devicecomprises the steps of measuring a fluid resistance coefficient of the carrier, calculating the mass of the carrier, adjusting the actual mass of the carrier and the like. By reasonably setting the fluid resistance coefficient and weight of the balance weight device, the carrier can be always attached to the upper surface of the sediment layer in a floating mode under traction of the traction rope, floating and sinking into the sediment layer are avoided, and a good foundation is laid for accurate measurement of the thickness of the sediment layer.

Description

technical field [0001] The invention relates to the technical field of water conservancy, in particular to a carrying device for an instrument for detecting the surface of an underwater sediment layer and a manufacturing method thereof. Background technique [0002] In sediment-laden rivers, the bottom of the river will be silted up due to changes in flow velocity. Detecting the silt shape to obtain the real river cross-section will help to better carry out related hydrological and water resources work. Generally, there are two methods for cross-section measurement. The first is field measurement method, that is, use two straightedges to intersect vertically from the middle pile to both sides of the cross-section to measure the distance and height difference of each point on the ground line, and organize the data to draw This method requires the tester to reach each feature point on the section. The second method is field measurement combined with total station measurement....
