Device for testing depth of encroached sea water

Abstract

The invention discloses a device for testing depth of encroached sea water, which comprises a water level and pressure sensor, an automatic controlling and recording module, a housing and a support. The water level and pressure sensor is used for measuring pressure of sea water, the automatic controlling and recording module is used for recording data of the water level and pressure sensor in real time, the support is mounted on the coast, the housing is mounted on the support, an upper sealed cavity and a lower cavity are arranged in the housing, the upper sealed cavity is used for mounting the automatic controlling and recording module, the lower cavity is used for mounting the water level and pressure sensor and provided with holes for sea water to inflow. The device for testing depth of encroached sea water has the advantages that the device can test dynamic change process of the depth of the encroached sea water in real time continuously, cannot be affected by weather, and can be prevented from damages or movement by matching between the housing and the support.

Description

technical field [0001] The invention relates to a marine test device, in particular to a device for testing the extent of seawater intrusion. Background technique [0002] my country has a long coastline and a wide variety of marine disasters. Among them, the seawater intrusion caused by strong typhoons every year seriously affects our country, especially the life and property of the people in the southeast coast. The huge waves caused by strong typhoon cross the coast or breakwater, enter the land lower than sea level or enter the estuary, and when the sea water enters the land lower than sea level, it will easily lead to the increase of salt in the coastal soil and compaction, which will further affect the yield and quality of agricultural products. decline; seawater entering the estuary will easily lead to the formation of fresh water in the estuary, which will affect the growth of freshwater organisms. Although the cause and harm of seawater intrusion have been recogniz...

Problems solved by technology

The huge waves caused by strong typhoon cross the coast or breakwater, enter the land lower than sea level or enter the estuary, and when the sea water enters the land lower than sea level, it will easily lead to the increase of salt in the coastal soil and compaction, which will further affect the yield and quality of agricultural products. Decrease; seawater entering the estuary will easily lead to the formation of fresh water in the estuary, which will affect the growth of freshwater organisms

Although the cause and harm of seawater intrusion have been recognized at present, and certain measures have been taken to prevent and control them, which have achieved certain results, but for the depth of seawater inversion at different locations in the coastal zone, due to the greater danger during seawater inversion, researchers The inability to approach the coastal zone for on-site testing prevented the researchers from directly measuring it, which made it impossible for the researchers to conduct data analysis on the extent and harm of the seawater intrusion
