Description

Technical Field

[0001] The utility model belongs to the technical field of pressure measuring tubes for lifting pressure, and more specifically relates to a novel auxiliary observation device for pressure measuring tubes. Background Art

[0002] A piezometer is a thin, glass-like instrument used to measure the relative pressure of liquids. Its primary function is to monitor the uplift pressure, the sum of the buoyancy and seepage pressure exerted by water seeping into a building and its foundation on a specific horizontal cross-section.

[0003] Patent No. CN212340526U discloses a hydraulic engineering pressure gauge, comprising an outer cylinder, wherein the inner walls of both sides of the outer cylinder are provided with a slide groove, and the inner walls of the slide groove are slidably connected to a sliding plate, the top outer wall of the sliding plate is connected to a fixed block by screws, and the top outer wall of the fixed block is connected to a wire rope by rivets, the other outer wall of the top of the outer cylinder is connected to a first support plate by screws, and the outer wall of one side of the top of the first support plate is connected to the support block by screws, and the other outer wall of the top of the first support plate is connected to two equidistantly distributed vertical plates by screws. After the pressure gauge has been used for a period of time, impurities accumulate on the surface of the filter screen and activated carbon plate. The motor pulls the filter screen and activated carbon plate up through the wire rope, cleans them, and then slides them to the bottom through the slide groove to clean the impurities in time, thereby avoiding malfunction of the pressure gauge and inaccurate measurement data.

[0004] Referring to the above-mentioned hydraulic engineering pressure gauge tube, when cleaning the filter screen, the filter screen is pulled upward and taken out for cleaning. This cleaning method causes the water entering the inner tube to be unfiltered due to the removal of the filter screen during the cleaning process, and some of its impurities will also enter the inner tube. When the filter screen is cleaned and put down again, the impurities in the inner tube may be blocked by the filter screen and cannot be discharged, thereby causing the impurities to always remain in the inner tube, affecting the accuracy of the water pressure measurement data.

[0005] Therefore, how to better clean the filter without removing it is an important issue that needs to be solved in the design of the new pressure tube auxiliary observation device. Utility Model Content
