All units of the layered detection unit are connected in series through unit connecting rods, and the lifting power mechanism drives the layered detection unit to move up and down along the lifting guide rail. The sliding door on the layered detection unit can be opened and closed under the push and pull of the micro electric cylinder, and the sliding door is closed when the tidal bore sediment content does not need to be detected, so that the detection instrument is protected, and the service life of the detection device is prolonged. According to the sediment content detection device, the lifting power mechanism drives the layered detection unit to adjust the height of the layered detection unit according to the height of tide water. And each subunit in the layered detection unit is used for carrying out online detection on the sand content in water flows with different layer heights, so that the detection data of the sand content has higher timeliness and analysis and comparison values.

Description

Technical Field

[0001] The invention relates to the technical field of engineering detection, and in particular to a device for detecting tidal stratified sediment content. Background Art

[0002] Understanding the sediment content in water flows at different levels helps analyze the scouring mechanism of the riverbed under the action of tidal bores, and provides important basic data for understanding the hydrological characteristics of estuary coastal environments, conducting basic theoretical research, and engineering practice applications. Traditional water sediment content detection mainly includes manual sampling by moored boats and fixed measuring instruments at the bottom of the observation platform. The former is unsafe under strong tidal bore conditions and will threaten the life safety of on-site observers. The latter cannot adjust the height of the detected water layer due to fixed installation, and cannot meet the needs of layered detection under large tidal ranges during astronomical high tides.

[0003] There is an urgent need to provide an automated detection device that can automatically adjust the height of the equipment according to the rise and fall of the water level and can detect the stratified sediment content of the water body online. Summary of the invention

[0004] The purpose of the present invention is to provide a tidal stratified sediment content detection device. The sediment content detection device adjusts the height of the stratified detection unit by a lifting power mechanism according to the height of the tidal water level, and each subunit in the stratified detection unit performs online detection of the sediment content of water flows at different layer heights, so that the detection data of the sediment content is more timely and has more analytical and comparative value.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a counter-radiation sensor array consisting of a sensor transmitting end and a sensor receiving end is installed in each layer structure of the layered detection unit, and the attenuation rate data of the ultrasonic signal intensity received by the sensor receiving end is used to reflect in real time the sediment content contained in the tidal water flowing through each layer of the detection unit.

[0006] Preferably, the sliding door on the layered detection unit can be opened and closed by the push and pull of the micro electric cylinder. When there is no need to detect the tidal sediment content, the sliding door is closed to protect the detection instrument and increase the practical life of the equipment.

[0007] Preferably, according to the change of the tidal water level, the lifting power mechanism composed of a gear rack mechanism can automatically adjust the height of the stratification detection unit, track the water level, and reflect the stratified sediment content in the tidal water body in real time.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] 1) In each layer structure of the layered detection unit 1 of the tidal stratified sediment content detection device, the sensor transmitting end 106 array is mounted on the sensor transmitting end mounting plate 105 behind the unit frame 101, and the sensor receiving end 107 array is mounted on the sensor receiving end mounting plate 108 behind the unit frame 101. By using the change in the attenuation rate of the intensity of the ultrasonic signal sent by the sensor transmitting end 106 received by the sensor receiving end 107, the change in the sediment content contained in the tidal water flowing through each layer of the detection unit can be detected in real time.

[0010] 2) The push-pull shaft 103 on the left side of the sliding door 102 of the tidal stratified sediment content detection device is pushed and pulled by the piston rod of the micro electric cylinder 104 fixed on the left side of the unit frame 101, and can be moved to the front of the unit frame 101 or to the left side of the unit frame 101. When it is moved to the front of the unit frame 101, the stratified detection unit 1 is closed, and when it is moved to the left side of the unit frame 101, the stratified detection unit 1 is opened. When the detection device is not needed to work, the sliding door is closed to protect the detection instrument and increase the service life of the equipment.

[0011] 3) The gear bracket 303 of the tidal bore stratified sediment content detection device is fixed on the support plate 2, the housing of the motor 301 is fixed on the gear bracket 303, the shaft of the motor 301 is coaxial with the gear 302, the gear 302 is driven to rotate, and moves up and down along the rack 304, thereby driving the support plate 2 and the multiple stratified detection units 1 to move up and down along the guide rod 402. According to the change of the tidal bore water level, the lifting power mechanism 3 composed of the gear rack mechanism can automatically adjust the height of the stratified detection unit 1 by tracking the water level, and reflect the stratified sediment content in the tidal bore water body in real time.
