At present, whatever plumb line coordinatometer runs stably, has high precision and strong reliability in the initial stage of installation, but after 2-3 years and more than 3-5 years of running, the phenomenon that the instrument works abnormally, the data continuity is poor, the precision is continuously reduced, the faults are continuous, even the operation cannot be carried out and the like starts to happen, and great hidden danger is brought to the safety management of the dam; in order to eliminate potential safety hazards of dam operation caused by the fact that the vertical line coordinatometer cannot work normally, a management unit can only maintain, repair, update and reform continuously, the workload is large, the economic burden is heavy, and the effect is not ideal; the operation is stable after each transformation, the operation is unstable more and more along with the time, even the cycle of the operation cannot be realized, the major hidden trouble of the vertical line coordinatometer for the safe operation of the dam cannot be fundamentally solved, and the huge economic loss is caused for a management unit. The reason for the phenomenon is that the vertical line coordinatometer is arranged on a dam gallery or a dam top and is in a moist and dull working environment for a long time, and the conditions are extremely bad; if in coastal areas, the content of corrosive substances such as salt in the air is higher, the environment is worse; the plumb line coordinatometer works in such an environment for a long time, the transmission part is extremely easy to rust and corrode, the electronic components are easy to be damaged by moisture, and the photoelectric sensing part is also easy to be affected by the moisture condensation to measure the value, so that the durability, the stability and the precision of the instrument cannot be fully ensured if the influence of the moisture and corrosive gas on the instrument is not solved in any instrument. The current common method is to independently establish an observation room for the plumb line coordinatometer, and adopt a dehumidifier to dehumidify the observation room uninterruptedly; or an observation box is independently built for the vertical line coordinatometer, and a heating device is arranged in the box body for uninterrupted heating. The two methods have high construction cost and high operation cost, require continuous maintenance, cannot ensure the dry environment of the instrument once power is cut off, can only solve the damp-proof problem, and cannot solve the problem that corrosive substances in the air in coastal areas damage the instrument; in addition, dehumidification and heating are carried out for a long time, so that the temperature of the instrument is inconsistent with the ambient temperature, and certain adverse effects can be generated on the service life and the observation precision of the instrument. Therefore, the moisture-proof and corrosion-proof problems of the plumb line coordinatometer are the problems to be solved urgently, and no effective solution is searched at home and abroad at present.
Therefore, it is necessary to develop a moisture proof protective cover for a plumb line coordinator.
