Shell structure and assembly method of multi-parameter water quality detection equipment

Abstract

The invention discloses a shell structure of multi-parameter water quality detection equipment and an assembly method thereof, comprising a hollow cylindrical shell with screw interfaces at both ends, and screw interfaces and threads for connecting watertight parts are arranged on the upper end cover of the shell The interface, the screw interface of the shell and the screw interface of the upper end cover are connected by screws. In addition, the copper column buried hole and the sealing groove for placing the sealing O ring are set on the part of the upper end cover located in the housing. By inserting the copper column buried hole The inner copper column fixes the circuit fixing plate in the shell on the upper end cover. In the shell structure disclosed by the present invention, in addition to connecting the upper and lower end covers with the shell, the two ends are respectively connected with a protective cover and a diversion cover, which are used to divert water and protect the probe and watertight parts. The protective cover and the diversion cover have the same structure , the side walls have notches, and the size of the notch opening is enough to accommodate the fingers of an adult male, so that on the one hand, it is symmetrical up and down, making the shell structure more beautiful, and on the other hand, the protective cover and the shroud can play the role of a handle , easy to carry.

Description

technical field [0001] The invention belongs to the field of marine water quality detection, and in particular relates to a shell structure of multi-parameter water quality detection equipment in the field and an assembly method thereof. Background technique [0002] In recent years, due to the needs of social and economic development, the development and utilization of marine resources has been increased, which has brought economic benefits and also caused a series of marine ecological environmental problems, causing serious damage to marine biological resources. As marine environmental protection has been paid more and more attention by the state, the marine environmental testing industry, as a subdivision of marine environmental protection, has also received attention from government departments at all levels. [0003] At present, most of the shell structures of multi-parameter water quality testing equipment commonly seen on the market have a single overall structure, lo...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the shell structures of multi-parameter water quality testing equipment commonly seen on the market have a single overall structure, low reusability, high price, and complicated assembly process. It is difficult to independently assemble the shell, and there are strong limitations in use. The cost is high, especially in the marine environment, there are serious problems of marine organism adhesion and shell pollution. It is a prerequisite for the normal operation of the detection equipment to be able to perform low-cost and high-quality maintenance conveniently. affect the accuracy of the collected data
