Damp-proof protective cover for plumb line coordinatograph

Abstract

The invention discloses a moisture-proof protective cover for a plumb line coordinatograph, and relates to the field of deformation measurement. The device comprises a box body, an instrument system, a waterproof system, freely movable sealing systems and a drying system, the box body comprises a bottom plate, a top plate and four panels connected with the bottom plate and the top plate, and the freely movable sealing systems are arranged on the bottom plate and the top plate; the instrument system comprises a coordinatograph and a hanging steel wire; the free movable sealing system comprises a cylindrical container outer wall, a cylindrical container inner wall, a cylindrical container bottom plate and a cylindrical cover, and the drying system is installed on the bottom plate. The protection device adopts a physical isolation mode, does not need a power supply, only needs to replace a drying agent in real time, is simple to maintain and low in operation cost, is a simple, economical and practical protection device, can effectively solve the moisture-proof and anti-corrosion problems of the plumb line coordinatograph, and has a wide market prospect.

Description

technical field [0001] The invention relates to the field of deformation measurement, in particular to a moisture-proof protective cover for a vertical coordinate instrument. Background technique [0002] my country has nearly 100,000 dams, which have made great contributions to flood control, drought relief, water supply, power generation, tourism, etc., and are of great significance to the national economy and people's lives. It is the primary task of project management; dam deformation is the main indicator of dam safety monitoring, and the vertical coordinate instrument is one of the commonly used horizontal displacement and vertical displacement deformation monitoring instruments for dam safety monitoring. Type, photoelectric type (CCD) and other types, belong to high-precision automatic monitoring instruments, which is of great significance to the safe operation of dams. [0003] At present, no matter what kind of vertical line coordinate instrument, the operation is re...

AI Technical Summary

Problems solved by technology

These two methods have high construction costs, high operating costs, and need for continuous maintenance. Once the power is cut off, the dry environment of the instrument cannot be guaranteed, and both can only solve the problem of moisture protection, and cannot solve the damage to the instrument caused by corrosive substances in the air in coastal areas. problem; in addition, long-term dehumidification and heating make the temperature of the instrument inconsistent with the ambient temperature, which will have a certain adverse effect on the life of the instrument and observation accuracy
