Water quality sampling equipment for hydrological monitoring

Abstract

The invention relates to the field of water conservancy equipment, and discloses water quality sampling equipment for hydrological monitoring. The equipment comprises an operation floating platform, amain cylinder, a water taking cylinder and a water sample storage tank, wherein multiple sets of sleeve blocks are slidably arranged on the main cylinder from top to bottom in a sleeving mode, the main cylinder at the bottom of each set of sleeve blocks is sleeved with a limiting sleeve which is limited to move through a fastening bolt, the water taking cylinder of a cylindrical structure is fixedly installed on the right side wall of each sleeve block downwards, a water outlet is formed in the bottom of the partition plate and used for communicating a pressure cavity with a water conveying cavity, the upper portion of the left side wall of the water conveying cavity is communicated with a drainage pipe arranged in the middle in the main cylinder, a transverse piston plate is slidably connected into the pressure cavity, a set of vertical piston rods with the top ends penetrating through the top wall of the pressure cavity are fixedly installed in the middle of the top of the piston plate, a set of lantern rings are fixedly installed on the top of the piston rods backwards through connecting rods, the lantern rings are jointly sleeved with a set of vertical sliding rods in a sliding mode, fastening bolts are arranged on the rear sides of the lantern rings, and a set of adjusting screws coaxial with the sliding rods are fixedly installed at the top of the sliding rods.

Description

technical field [0001] The invention relates to the field of water conservancy equipment, in particular to water quality sampling equipment for hydrological monitoring. Background technique [0002] Environmental pollution refers to natural or man-made destruction, the behavior of adding certain substances to the environment and exceeding the self-purification ability of the environment and causing harm. It is one of the three major global crises. In order to prevent and control environmental pollution, it is necessary to monitor the environment. Through the detection of the content and discharge of various substances that have an impact on humans and the environment, track changes in environmental quality, determine the level of environmental quality, and provide support for environmental management and pollution control. Provide the basis and guarantee. [0003] The existing water intake device for hydrological detection cannot simultaneously perform water intake at multi...

Problems solved by technology

[0003] The existing water intake device for hydrological detection cannot simultaneously perform water intake at multiple depth levels according to the required requirements when drawing water from the water level at the same position. The common existing operation uses the control lifting structure to drive the water intake components separately To adjust the depth, first of all, this operation is difficult in the water. Using the same water intake component to draw water at different depths will easily cause river water in different positions to mix with each other, which will affect the accuracy of detection. Therefore, it is necessary to design a water quality that can solve the above problems. Check the water intake device
