Topography
observation device
based on mechanical
fine tuning dual hosts
CN108534758
(A)—2018-04-08
The invention belongs to the technical field of water and soil conservation study devices, and relates to a
dynamic observation device used for a slope topography evolution process. The two hosts emit parallel,
equal-height and overlapping laser planes from different orientations, and the laser planes are projected
onto the slope topography; an image collecting device shoots the slope topography which laser rays are
projected onto at an angle perpendicular to the layer planes to form a video screenshot, the video
screenshot is imported into a computer to form a three-dimensional stereogram, and then parameters
such as the slope volume and the slope gradient are calculated. According to the device, by rotating
rotary knobs of mechanical fine tuning devices in the topographic meter hosts, equal-interval parallel
accurate adjustment of laser ray planes is achieved; according to the device, by observing a fixing bolt
on a support and a worm handle rotary knob in a view screen box, moving and rotation of a camera used
for image collection are controlled. The invention provides a novel topographic meter through which the
spacing and the angle of a linear laser can be conveniently calibrated, and all the topographies including
local deep grooves on an eroded slope can be accurately observed

transporting in a river
(ZL201511024920.8)
CN105403435
(A)—2016-03-16
The invention provides a three-dimensional sampling device for simulating transport of river
contaminations. The three- dimensional sampling device is composed of a bank control point, a
catamaran sampling platform and a multi-point sampler. The device is characterized in that the
catamaran sampling platform moves in a river under the control of the bank control point; and when the
catamaran sampling platform reaches a sampling position, the multi-point sampler installed on a
sampling device takes water samples at different water depths and different distances from an initial
point from a to-be-measured section. The three-dimensional sampling device provided by the invention
can meet requirements for safety, easy operation, small disturbance to a flow field of river water and the
like at the same time, has high sampling efficiency and accurate sampling position and guarantees
accuracy and representativeness of the water samples
