AI Technical Summary

Technical Problem

Existing sludge sampling devices are inconvenient to operate in deep water environments, and the length and weight of traditional sampling tubes limit the operational requirements of staff, posing risks of inconvenient sampling and sample leakage.

Method used

The device employs an opening and closing mechanism, a metal hose, and a steel cable structure. The opening and closing of the sampling shell is controlled by the steel cable. Combined with the disassembly and assembly components, the device can flexibly sample under various water depth conditions. The cooperation between the metal hose and the steel cable ensures that the sample is not easily leaked.

Benefits of technology

It enables convenient and safe silt sampling in deep water environments, reduces operational requirements, improves the reliability and accuracy of the sampling process, and facilitates the maintenance and cleaning of the device.

Abstract

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.
