Description

Protective device of potential acquisition instrument Technical Field The utility model relates to the technical field of potential acquisition instruments, in particular to a protective device of a potential acquisition instrument. Background The potential acquisition instrument ‌, also called as a cathodic protection potential tester, is an intelligent device for monitoring and recording the potential value of a metal structure (such as a pipeline, a storage tank, a ship and the like) in a cathodic protection system, and the effectiveness of the cathodic protection system is evaluated by measuring the potential difference between the metal structure and a reference electrode, so that the metal is prevented from being corroded. The potential acquisition instrument is widely applied to various fields such as industrial production and scientific research experiments, in the actual use process, the potential acquisition instrument is often subjected to vibration generated in the transportation process or during the running of equipment, so that the internal elements of the potential acquisition instrument are easy to loosen or damage, the accuracy of acquired data is affected, in addition, the internal circuits of the potential acquisition instrument are affected by damp in a moist environment, faults such as short circuit are caused, the normal running of the equipment is affected, and the safety is insufficient. Therefore, it is necessary to redesign the protection device ‌ of the potential acquisition device to solve the above-mentioned problems. Disclosure of utility model The utility model aims to solve the defects in the prior art and provides a protective device of a potential acquisition instrument. In order to achieve the above purpose, the present utility model adopts the following technical scheme: The utility model provides a protector of electric potential collection appearance, includes the protective housing, the inside rotation of protective housing installs the door of opening and close, protective housing both sides inner wall all has the slide bar through connecting frame fixed mounting, two the equal slidable mounting of slide bar outer wall has the buffer board, two buffer spring is all installed to the slide bar outer wall, two buffer spring both ends respectively with the connecting frame inner wall and the buffer board diapire elastic connection of homonymy, two the common fixedly connected with mounting panel of buffer board tip, wall fixed mounting has two damping telescopic links in the protective housing, two the flexible end of damping telescopic link all with mounting panel diapire fixed connection.
