4results about How to "Flexible sampling" patented technology

This utility model relates to the technical field of liquid sampling equipment, and in particular to an easy-to-operate liquid sampling device that solves the problems of easy sample contamination, unstable sampling posture, easy leakage during sample transfer, and difficulty in adapting to complex liquid sampling needs in the prior art. An easy-to-operate liquid sampling device includes a sampling cup with a top cover fixedly installed at the top, and a dustproof flip cover movably installed at the top of the top cover. The bottom of the sampling cup has an opening, and an adsorption structure is installed at the bottom of the sampling cup corresponding to the opening. This utility model isolates external impurities through the double-sealing design of the dustproof flip cover, maintains the vertical posture of the sampling cup with the help of a counterweight base, and achieves bidirectional and efficient liquid intake by balancing air pressure with a vent pipe. After sampling, the sample is sealed by the sealing suction cup and the dustproof flip cover, effectively improving the convenience, accuracy, and reliability of the sampling operation, and adapting to various liquid types and sampling scenarios.

This utility model discloses an adjustable negative pressure boiler slag sampling device. A plug is installed at the open end of an elliptical cross-section sampling container, which is eccentrically connected to the container via an eccentric rotating shaft. The elliptical cross-section sampling container is fixedly connected to a pull ring handle unit via a spoon handle. The pull ring handle unit includes an opening and closing linkage mechanism and a limit adjustment mechanism. The opening and closing linkage mechanism includes a pull ring, a connecting shaft, and a return spring. The connecting shaft is installed inside the hollow spoon handle, with one end connected to the pull ring and the other end connected to the eccentric rotating shaft. The return spring is sleeved on one end of the connecting shaft, which has a raised guide shaft. The limit adjustment mechanism is located at one end of the spoon handle and has an oblique spiral guide groove. The raised guide shaft is slidably installed within the spiral guide groove. This utility model features a simple and stable process, improves sampling efficiency, and is adaptable to different negative pressure intensities, effectively preventing slag from being sucked back under negative pressure.

This utility model relates to a sludge sampling device, belonging to the field of sludge sampling technology. The sludge sampling device includes: a connecting shaft and two sampling shells hinged to the connecting shaft; the opening and closing mechanism includes a first hinge block disposed inside the sampling shell, two first telescopic rods disposed between the first hinge block and the inner wall of the sampling shell, and two second telescopic rods disposed between the two first telescopic rods; by setting up the opening and closing mechanism in conjunction with a metal hose and a steel cable, the sludge sampling device can flexibly sample under various water depth conditions, without worrying about the limitation of the sampling tube length. Compared with traditional sampling tubes, the steel cable structure is smaller and lighter, greatly reducing the requirements for operator operation and making the sampling process more convenient and safer. Furthermore, the use of the metal hose and steel cable together ensures that the sample is not easily leaked during the sampling process, improving the reliability and accuracy of the sampling.
