Description

Simple type adjustable liquid level meter protection device Technical Field The utility model relates to the field of liquid level meter protection, in particular to a simple type adjustable liquid level meter protection device. Background The liquid level meter is an instrument for automatically measuring and recording water levels of rivers, lakes, channels and other water bodies, has the advantages of good stability, corrosion resistance, abrasion resistance, convenient installation and the like, and is widely used in water level measurement of domestic sewage and industrial sewage. Although the level gauge has the advantage of wear resistance, because the level gauge is not fixed during installation, a large amount of solid particles in sewage are in direct contact with the level gauge for a long time and further worn out under relative movement, and a large amount of suspended matters in the medium interfere with the accuracy of the level gauge and greatly reduce the service life of the level gauge. In municipal administration and industrial sewage treatment scene, traditional level gauge is difficult to adapt to the water level fluctuation because of fixed mounting mode, and in the direct exposure contains solid particle, fibre and corrosive medium's sewage, easily receive wearing and tearing and lead to measurement accuracy decline and life-span to shorten, and rigid connection's integrated structure causes installation maintenance inconvenience, space occupation to be big simultaneously. The existing adjustable support, protective sleeve and other technologies are improved, but the adjustable support and protective sleeve have the defects of easy looseness of an adjusting mechanism, insufficient sealing protection, poor space suitability and the like. Disclosure of utility model The utility model aims to provide a simple type adjustable liquid level meter protection device, which realizes height adjustment through a fixed support, an L-shaped cantilever and a cantilever guide rail in threaded connection, isolates the liquid level meter from sewage medium by utilizing a protection sleeve with a grating, and is matched with a gasket and a sealing ring for sealing and buffering, so that the liquid level meter can be dynamically adapted to water level change and is protected from abrasion so as to prolong the service life. In order to achieve the above purpose, the present utility model provides the following technical solutions: The simple type adjustable liquid level meter protection device comprises a fixing support and is characterized in that the fixing support is plate-shaped, the upper portion of the fixing support is bent, a plurality of fixing holes are formed in the fixing support, 1 or a plurality of straight notch are formed in the lower portion of the fixing support, a cantilever is fixedly installed on the straight notch, a cantilever guide rail is arranged at the other end of the cantilever, the cantilever guide rail comprises a placing groove, and a protection sleeve is installed in the placing groove.
