Description

TECHNICAL FIELD

[0001] The application relates to the technical field of water source detection sampling, in particular to a water source detection sampling instrument for engineering geological survey. BACKGROUND

[0002] The water source detection sampling instrument for engineering geological survey is a special instrument for collecting water samples during geological survey, mainly used in the fields of hydrogeological investigation, groundwater resource evaluation, pollutant monitoring, environmental protection and the like. The instrument can help engineering geologists obtain accurate water samples and monitor and analyze water quality, thereby providing data support for engineering design, construction and post-management.

[0003] The water source detection sampling instrument for engineering geological survey is an important tool widely used in the fields of groundwater monitoring, water quality analysis and hydrogeological survey. Through accurate and efficient water sampling, scientific basis can be provided for engineering construction, environmental monitoring and water resource protection. When purchasing and using the instrument, attention should be paid to the technical parameters of the equipment, the use scenarios and the daily maintenance, so as to ensure the accuracy of the data and the long-term stability of the instrument.

[0004] The document with the prior art publication number CN221350671U provides a water source detection sampling instrument for engineering geological survey. When the sampler needs to sample and detect the water source in a certain water area, the sampler connects the ship body to the first connecting ring on the utility model through the connecting rope. After the ship body drives the utility model to move above the water source to be detected, the sampler starts the speed reducer. The rotation of the roller body will cause the connecting rope to be released. When the connecting rope is released, the sampling box moves downward. The liquid level detection sensor detects the distance between the sampling box and the liquid surface in real time. When the liquid level detection sensor detects that the liquid level data value is within the preset liquid level data value range, the PLC controller controls the speed reducer to be closed. Then, the PLC controller controls the electromagnetic valve on the inlet and outlet pipe of the liquid taking tank to be opened. The water source at this depth flows into the cavity in the sampling tank for storage. The sampler controls the corresponding electromagnetic valve on the inlet and outlet pipe through the PLC controller to be closed. Thus, the utility model is convenient for the sampler to accurately sample the water source at different depths, and is easy to operate and use.

[0005] Although the prior art scheme in the above can achieve the beneficial effects related to the prior art, it still has the following defects: when the device is in use, it is inconvenient to remove the solid suspended matter or sediment in the water sample, which affects the accuracy of the detection data and has poor practicality.

[0006] In view of this, we propose a water source detection sampling instrument for engineering geological survey. The utility model discloses
