Technical Field

Background

Tidal beaches are sedimentary areas periodically submerged and exposed under the action of tides developed in estuary coastal zones. Tidal beaches can be classified into sandy tidal beaches, silty tidal beaches, and the like according to their physical composition. Tidal flats are influenced by variable sea-land interaction, processes such as tides, runoff, waves and monsoon are mutually coupled, and the power process is complex; meanwhile, the tidal flat is used as a special zone influenced by sediment-water-gas and is a place with the largest span of various physical and chemical gradients. The tidal flat has the functions of stabilizing seawalls, buffering storm tide invasion, providing biological habitat and the like. In recent years, excessive development and utilization of tidal beaches weaken the disaster prevention and reduction capability of coastal zones, the ecological system is seriously degraded, and the environmental and ecological problems caused by the serious ecological system are increasingly highlighted. This is due to the fact that the knowledge of the tidal flat is not enough. The method has the advantages that data such as tidal flat high-precision temperature, salinity, waves and suspended sand concentration are acquired and analyzed, scientific guidance on river mouth and coast engineering design, disaster prevention and reduction and development management are facilitated, and certain theoretical significance and engineering significance are achieved.

Compared with an object model experiment and numerical simulation, the in-situ monitoring can obtain the most reliable and real data, but is greatly restricted by natural conditions. The silt tidal flat is relatively widely developed in China, the substrate is generally high in water content, soft and easy to sink, and the tidal flat is difficult to monitor by manpower. In addition, the strong corrosiveness of seawater, the interference of vegetation on the deployment of instruments, and the like are issues that must be addressed. The CTD (conductivity Temperature depth) is the Temperature and salt depth measuring instrument with highest precision, most use and most stable performance in the current physical marine measurement. When the CTD is applied to tidal flat measurement, a single CTD can only automatically acquire single-point temperature and salinity depth time sequence data, which brings many limitations to subsequent data analysis; increasing the number of instruments will also increase costs. In the related published or granted patents, the disclosed technical solutions mostly focus on the installation of instrument supports suitable for tidal flat environment, do not relate to the function of acquiring multi-layer environmental data of the tidal flat inside, water body and water surface in the special environment of the tidal flat, and have less design of devices for stable observation and high-precision vertical positioning observation of the tidal flat.

Aiming at the defects of the prior art, the comprehensive tidal flat, water body and water surface environment parameter monitoring device is low in cost, relatively portable and wide in applicability, realizes stable and high-precision positioning measurement and monitoring of multiple vertical layers of parameters of the tidal flat, the water body and the water surface, and provides reliable support for research of a tidal flat power mechanism.

Preparing a sufficient number of data acquisition boxes 6, checking the dry battery electric quantity and TF memory card storage space in the data acquisition boxes, and respectively arranging the data acquisition boxes at the target height of the middle shaft through the hose clamp structure by means of the scale of the main shaft mark.

The dry battery electric quantity inside the GPS positioning ball 7 is checked and is arranged at the top end of the middle shaft through a stainless steel screw.

And carrying out field sea test on the tidal flat of the target sea area by the device, and checking the sensor.

Step two, the device is arranged to the target tidal flat.

The foot pad 8 on the medial axis and foot tube is removed and the assembled device foot tube and the following parts are inserted into the tidal flat. If the device is seriously sunk, the position, area and size of the anti-sinking ring can be adjusted.

And step three, acquiring data of the data acquisition box and the GPS positioning ball.

A schematic of the data acquisition cartridge is shown in fig. 4. The data acquisition cartridge includes an outer waterproof structure 12 and an internal data acquisition system. The external waterproof structure adopts tight screw threads for waterproofing. The internal data acquisition system comprises a power supply module 13, a data storage module 14, a singlechip 15 and a sensor module 16. The workflow of the data acquisition box is as follows. The power supply module provides power for the sensor module, the singlechip and the data storage module by means of a dry battery in the battery bin. Sensor probes 17 (including but not limited to temperature sensors, conductivity sensors, pressure sensors, optical sensors) affixed to the outside of the data acquisition box acquire corresponding physical marine parameter signals. For example, a temperature sensor may be used to obtain a seawater temperature digital signal, a conductivity sensor may be used to obtain a seawater conductivity digital signal, a conductivity value may be used to calculate salinity data, a pressure sensor may be used to obtain a seawater pressure digital signal, a pressure value may be used to calculate water depth data, high frequency water depth data may be used to calculate wave parameters, an optical sensor may be used to collect seawater turbidity data, and a water body suspended sand concentration value may be calculated via calibration.

The singlechip regularly receives and processes signals acquired by the sensor module, calculates the temperature, salinity, water depth, wave, suspended sand concentration and erosion and deposition depth profile values of seawater and tidal beaches, drives the data storage module, and records the digital signals of the sensor in a text form in the TF card.

A schematic diagram of a GPS location sphere is shown in fig. 5. The GPS positioning ball comprises a plastic shell 18, a waterproof gasket 19, a battery bin 20 and a positioning terminal 21. The plastic shell and the waterproof gasket are used for isolating seawater. The positioning terminal can periodically send the current position information to the remote computer by the power supply of the dry battery.

In the step, the data acquisition of the data acquisition box and the GPS positioning ball are both automatic processes driven by electric energy. The device can work on the tidal flat for a long time without being attended, and a monitor only needs to check whether the GPS position of the device has a great deviation through a remote computer to judge whether data acquisition is normal.

And fourthly, maintaining the device. The battery, sensors, stability, etc. of the device are regularly maintained.

And fifthly, recovering the device and processing data.

And recovering the device according to the GPS coordinates in a preset time. The stored data information can be viewed and analyzed through the TF memory cards in the data acquisition boxes.

The three-leg-frame-shaped foot tubes are completely embedded into sediments, and only the long-rod-shaped middle shaft is exposed, so that the fixing effect is enhanced, and the acting area of wave flow force is reduced; the design of the anti-trap ring can increase the contact area of the device and the bed besides being used as a ring for connecting all parts. The invention can synchronously acquire the set depth in the tidal flat, the specific water depth in the water body and the parameters of the water surface at fixed points and fixed heights, and is suitable for synchronously acquiring the parameters of the tidal flat, the water body and the water surface of a mud flat (easy sinking and inaccurate measurement caused by the sinking and the inclination) due to strong tide (the tidal range is more than 5m, instruments are difficult to carry, and the flow velocity is strong, the instruments are easy to incline).

While the foregoing has described in detail the principles, principal features and embodiments of the invention, it will be understood that the foregoing is only one embodiment of the invention and is not intended to limit the invention in any way. Any equivalent substitutions or modifications made within the scope of the present invention should be included in the protection scope of the present invention.
