Description

TECHNICAL FIELD

[0001] The utility model relates to the field of drinking water detection, concretely to a detection sampling device for drinking water production and preparation. BACKGROUND

[0002] Drinking water detection is a key link to guarantee the safety of the people's drinking water, and it is related to the health and well-being of every person. The detection content is complex and delicate, covering microbial indicators such as bacteria, viruses and parasites. The content is strictly controlled to prevent intestinal diseases. Chemical substance indicators are also critical. Heavy metals (such as lead and mercury), organic pollutants, residual chlorine, and pH, hardness, etc. in water are detected to avoid the intake of harmful substances by the human body and maintain the taste and sensory properties of water. Visual observation of the color and turbidity of the water, and the smell of the water, can ensure that the water is clear and odorless.

[0003] To accurately control water quality, drinking water production and preparation are equipped with a detection sampling device. The device is provided with an opening at both ends, and a sealing plate is movably arranged in the opening. Generally, a rope is connected to the device. When using the device, the operator first throws the device into the river. Because the container itself is heavy and the sealing plate is light, the sealing plate will delay falling at the moment the container is lowered, thereby forming a gap for water to enter. When the operator controls the container to be at a certain height through the rope, the container first becomes stationary, and the sealing plate falls into the opening to close the opening under the action of gravity. The inner side of the opening is generally provided with a protrusion to hold the sealing plate. When the container is lifted upward, the protrusion restricts the sealing plate from sliding downward under the action of inertia, so the opening is always in a closed state when the container is lifted upward, thereby realizing automatic opening and closing of the river water sampling device during sampling.

[0004] However, because the depth of drinking water is inconsistent, the water quality is also inconsistent, so water quality samples of different depths are needed. The sampling device has a simple structure and can only obtain water quality samples of one depth at a time. Multiple sampling is required to obtain water quality samples of different depths, which is time-consuming and labor-intensive, and extremely inconvenient to use. Therefore, the existing technology needs to be improved. UTILITY MODEL CONTENT

[0016] Further, the extrusion groove is designed to be inclined, and the end of the extrusion block is located inside the extrusion groove.

[0017] By adopting the above technical scheme, the inclined design of the extrusion groove provides a movement trajectory guide for the movement of the extrusion block, ensuring that the extrusion block moves in the designed direction and path, avoiding the situation that the extrusion block is stuck or damaged due to deviation of the movement direction.
