Description

Technical Field

[0001] The utility model relates to the technical field of raw water quality monitoring, in particular to a tortoise monitoring water tank for water quality monitoring. Background Art

[0002] Sudden water pollution refers to a pollution accident caused by the sudden leakage or discharge of pollutants, which causes the water quality in the raw water source protection area to deteriorate severely instantly and seriously threatens the water intake safety of the water plant. Although departments at all levels have taken very thoughtful and strict protection measures for the water source protection area, upstream pollution, factory accidents and deliberate illegal discharge, chemical (oil) leakage caused by transport ship or vehicle accidents, non-point source pollution washed into the river water by heavy rain, etc., are very likely to cause sudden water pollution accidents, which are difficult to prevent. Related cases are not uncommon. Although the current chemical analysis method has the advantages of standardization, precision and quantification, it has the disadvantages of being time-consuming, severely lagging, and discontinuous monitoring and data indicators caused by intermittent sampling, which easily ignore the antagonism, addition and synergy between influencing factors, especially the synergistic amplification effect, and cannot directly reflect biological tolerance.

[0003] For example, a Chinese patent (publication number: CN212872435U) discloses a biological monitoring water tank for water quality monitoring, including a water tank body, one side of the water tank body is provided with a water inlet pipe, and the other side is provided with a water outlet pipe; a partition is vertically provided in the water tank body, and a water gap is formed between the lower side of the partition and the bottom of the water tank body; a water inlet cavity is formed between one side of the partition and the side wall of the water tank body, and a water sample storage cavity is formed between the other side and the side wall of the water tank body, the water inlet pipe is connected with the water inlet cavity, and the water outlet pipe is connected with the water sample storage cavity. The utility model can prolong the residence time of raw water after entering the water tank, so that the raw water can be more fully mixed with the water sample in the water tank after entering the water tank, effectively avoiding the formation of local dead water, thereby effectively improving the reliability and stability of raw water monitoring.

[0004] The above-mentioned biological monitoring water tank for water quality monitoring still has certain shortcomings. On the opposite side walls of the water tank body, a slide groove is respectively provided at the positions corresponding to the two sides of the partition. The two sides of the partition are located in the two slide grooves and are connected with the water tank body in a sliding manner. On one side of the partition, an adjusting screw rod is also vertically provided. The upper end of the screw rod extends to the top of the partition and is connected to an adjusting handle, and the lower end is rotatably connected to the bottom of the water tank body. The partition is driven to move by rotating the adjusting handle, but the screw rod is not convenient for limiting. Under the impact of water flow, the screw rod may rotate, resulting in the screw rod being unable to limit the partition, affecting the use of the partition. Therefore, a tortoise monitoring water tank for water quality monitoring is proposed to solve the above problems. Utility Model Content
