Real-time continuous in-situ water body monitoring device for freezing period

Abstract

The invention relates to the technical field of water body monitoring, in particular to a real-time continuous in-situ water body monitoring device for a freezing period, which comprises a monitoring mechanism and an adjusting mechanism, the monitoring mechanism comprises a dark acrylic pipe and a bright acrylic pipe, the top of the dark acrylic pipe and the top of the bright acrylic pipe are both provided with sealing devices, dissolved oxygen probes are suspended in the dark acrylic tube and the bright acrylic tube, fine lines are bound on the dissolved oxygen probes and penetrate through the sealing device, chucks are arranged in the middle of the dark acrylic tube and the bright acrylic tube, and the adjusting mechanism comprises a fixing frame and two sets of adjusting frames. The adjusting frames slides on the fixing frame and are connected through a fastening screw, concave surfaces are formed in the side walls of one sides of the adjusting frames, adjusting handles are rotationally arranged on the adjusting frames on the same sides of the concave surfaces, and adjusting plates are movably hinged to the end of the adjusting handles. According to the invention, the real-time monitoring effect of the primary productivity of the subglacial water body in the freezing period can be obviously improved, and the measurement precision is improved.

Description

technical field [0001] The invention relates to the technical field of water body monitoring, in particular to a real-time continuous in-situ water body monitoring device used in the ice-covered period. Background technique [0002] Comprehensively and completely estimate the metabolic process of the subglacial water ecosystem during the ice-covered period. It can continuously monitor the oxygen consumption process of the sediment and the respiration and oxygen consumption of aquatic plants in real time. The real-time oxygen balance of the subglacial water body, and the real-time continuous in-situ monitoring of the primary productivity of the subglacial water body during the ice-covered period.

[0003] In addition, some water bodies in cold regions are accompanied by snowfall in winter, and the ice surface of ice-covered water bodies will also be covered with snow for different days and thicknesses. When snow covers the ice surface of lakes, it basically prevents the light from entering, resulting in Stop, photosynthetic oxygen production is zero, the environment is gradually hypoxic, and a series of environmental deterioration phenomena such as enhanced reduction

The snow cover process in some areas is relatively short. According to the existing technology, when the snow cover history is particularly short, the water quality sampling cannot be completed in time, and the primary productivity of the subglacial water body cannot be monitored in time. Primary Productivity of Water Bodies
