Problems solved by technology

[0003] The circulating water tank device can simulate the dynamic water conditions of the natural water environment to a large extent, such as the distribution of water flow, the influence of hydrodynamic force on the mud-water interface, the migration and transformation process of pollutants in water, etc., but the existing circulating water tank devices are generally suitable for water The research on the sediment medium is relatively weak, which makes it more inconvenient for researchers to study the sediment environment

Embodiment 1

[0036] A circulating tank that can simulate the environment of river sediments, such as figure 1 As shown, including a sediment test system, said circulating water tank also includes a circulating water system provided with a water collection tank 1 and a return tank 8;

[0037] The sediment test system is installed on the circulating water system;

[0038] The following can be referred to Figure 1~5 :

[0039] In order to simulate sediment environments such as rivers, the sediment test system is provided with a plurality of incubators 5 distributed in an array, and each incubator 5 is set independently and can be taken out in batches to detect sediments at different time points state, and a sediment test tank 4 is installed between the incubators 5 distributed in a plurality of arrays, and on the side wall of the incubator 5, a plurality of interstitial water intake holes 6 are sequentially opened from top to bottom, so that in the incubator 5 inside Take sediment interst...

Embodiment 2

[0051] An embodiment of the present invention provides a circulating water tank capable of simulating a river sediment environment, which is specifically further defined on the basis of Embodiment 1.

[0052] Such as figure 1 and Figure 5As shown, the power regulating system is provided with a motor 17, and a motor box 9 is installed outside the motor 17, and the motor box 9 is installed on the return water tank 8, and the control panel 10 is installed on the motor box 9, and the propeller 18 is fixed on the On the output shaft of the motor 17, the propeller 18 penetrates into the return water tank 8 inside.

[0053] Further, the water return tank 8 is provided with a drain port 12 .

[0054] Driven by the power adjustment system, the water flows in the water collection tank 1 through the shrinkage section 2 to stabilize the water flow, enters the test tank 13, flows from the tank outlet plate 7 into the return water tank 8, and then flows into the water collection tank 1 t...

Abstract

The invention relates to a water groove, in particular to a circulating water groove capable of simulating the riverway sediment environment. A sediment test system is included. The circulating watergroove further comprises a circulating water system provided with a water collecting box and a water returning box; the sediment test system is provided with a plurality of culturing boxes distributedin an array shape; sediment test grooves are installed between the multiple culturing boxes, and are designed to be capable of simulating the sediment environment of a river and the like; the culturing boxes are independently arranged, and can be taken out in batches, so that sediment states at different time points are detected; a water groove outflow plate is additionally arranged between the water collecting box and the water returning box; a power adjusting system is installed on the water returning box, and is provided with a control panel; an outflow plate sleeve plate for an outflow plate inner plate to penetrate through and be inserted in is arranged on the water groove outflow plate, and the outflow plate sleeve plate and the outflow plate inner plate are both provided with outflow holes; and the alignment degree of the outflow holes is adjusted, and in cooperation with control of the power adjusting system and the control panel, the water depth and the flow speed can both beadjusted.

Description

technical field [0001] The invention relates to a water tank, in particular to a circulating water tank capable of simulating the sediment environment of a river course. Background technique [0002] Pollutants that enter the aquatic environment usually sink in sediment, but are not stable. When the physical and chemical characteristics such as oxygen content and pH of the overlying water-sediment micro-interface change, or the sediment is disturbed, the pollutants settled in the sediment will be released again, threatening the health of the water environment. In the process of research on the prevention and control of pollutants in sediments, experimental equipment that can simulate the environment of river sediments is often used to explore the migration and transformation mechanisms of pollutants in sediments and pollution remediation technologies. [0003] The circulating water tank device can simulate the dynamic water conditions of the natural water environment to a l...
