3results about How to "Meet sampling needs" patented technology

This utility model relates to the technical field of water quality sampler brackets, specifically to a portable water quality sampler bracket, including a base and a support mechanism. The support mechanism includes a support component, a transmission component, and a reinforcement component. The support component includes a support cylinder disposed above the base. Multiple support rods are fixedly connected between the side wall of the support cylinder and the upper surface of the base. A top plate is fixedly connected to the top of the support cylinder, and an electric telescopic rod is fixedly installed on the bottom surface of the top plate. This utility model, through its support component, enables precise and rapid adjustment of the mounting bracket height to meet the sampling needs of water bodies at different depths. The reinforcement component significantly enhances the stability of the bracket in complex environments, effectively resisting the impact of water flow, wind, and other external forces, ensuring the stability of the water quality sampler during sampling.

The utility model discloses a kind of sampling devices for food safety detection, it is related to food detection technical field, including sampling cylinder, the bottom of the sampling cylinder is respectively fixedly connected with large pipe diameter pipette and small pipe diameter pipette, the inner wall bottom of the sampling cylinder is movably connected with adjusting closure plate, the upper surface of the adjusting closure plate is equipped with butt joint hole one and butt joint hole two.The utility model can be according to food and beverage type, such as whether containing fruit pulp particle, quickly switch using different pipe diameter pipette to sample, greatly improve the adaptability of sampling, ensure that various samples can be accurately extracted, sampling length is adjustable, convenient and efficient operation: large pipe diameter pipette inner wall screw connection built-in threaded pipette, when needing to change sampling pipette length, built-in threaded pipette can be realized by using threaded rotation extraction, easy operation, meet the sampling demand of different depth or special position sample.

This invention discloses a greenhouse gas sampling device and method for soil layers. The sampling device includes a sampling support with a layering mechanism along its length, dividing the support into several sampling zones. Each sampling zone contains a sampling cylinder for sampling gases at a corresponding depth, and the sampling cylinder is fixed to the layering mechanism. The layering mechanism includes an adjusting plate and a sealing ring embedded around the adjusting plate. The adjusting plate is limited by an adjusting rod on the sampling support, and the adjusting plate and the adjusting rod are screwed together. A driving mechanism is located below the sampling support to rotate the adjusting rod and adjust the layering depth of the sampling zone. The adjusting plate and the adjusting rod are screwed together, and the driving mechanism drives the adjusting rod to rotate, thereby adjusting the height of the adjusting plate. This allows the device to meet the greenhouse gas sampling needs under different environments and improves its adaptability.
