Humanity hole orifice cover

Abstract

The invention discloses a humanity hole orifice cover. The humanity hole orifice cover comprises a sleeve and a clamping mechanism which is arranged in the sleeve; the sleeve comprises a circular ring body and an annular platform which is formed at the upper end of the circular ring body; the outer diameter of the annular platform is larger than the hole diameter of a humanity hole; the inner side of the circular ring body is provided with more than one sliding groove; a sliding block is arranged in every sliding groove; every sliding block comprises a sliding block body and connecting blocks with holes, wherein the connecting blocks extend from two ends of every sliding block body respectively; the clamping mechanism comprises a spring, a fastening bolt, a nut and two hinge pieces with through holes; the two hinge pieces with the through holes are connected together through a pin shaft due to every sliding block so as to enable the two hinge pieces to form a hinge; the fastening bolt penetrates the holes formed in the two hinge pieces respectively to enable the hinge to form an opening; the spring is horizontally arranged in the opening. According to the humanity hole orifice cover, the opening is a horizontal plane and accordingly the measurement of a water level meter is not affected and the clamping mechanism is used for clamping a fixed measuring line so as to reduce the impact of the measuring line slipping-down or measuring line break points on the monitoring accuracy.

Description

technical field [0001] The invention belongs to the field of geological disaster monitoring and design, and in particular relates to a manhole hole cover. Background technique [0002] Groundwater level monitoring is particularly important to the prevention and control of geological disasters. At present, a large number of groundwater level monitoring work has been carried out at home and abroad. The distribution of groundwater level in the landslide body directly affects the distribution of saturation of the landslide body, and engineering problems such as the calculation of hydrodynamic pressure play a vital role in the calculation of landslide stability and risk control. In terms of mechanism research, the research on the response relationship between groundwater level, rainfall and reservoir water level has received extensive attention. [0003] At present, fully automatic (semi-automatic) groundwater monitoring equipment is mainly used, that is, a pressure sensing prob...

AI Technical Summary

Problems solved by technology

However, the preparation of the existing hydrological holes and the installation of the water level gauge are particularly rough. The orifices of the hydrological holes are often uneven due to manual pipe cutting, so when measuring, the measurement error is relatively large; the installation of the water level gauge is often not uniform. When the cover is installed, there are often problems such as the measurement line slipping and the breaking point of the measurement line being worn, which directly affects the monitoring accuracy.
