Description
Technical Field
The utility model belongs to an improvement, especially a modified is used for monitoring osmometer of hydraulic structure seepage water pressure for monitoring the improvement of osmometer structure of hydraulic structure seepage water pressure.
Background
The seepage pressure monitoring is a necessary project for safety monitoring of hydraulic buildings, particularly reservoir dams, the seepage-proofing effect of the seepage-proofing body can be known by measuring the seepage water pressure in the dam foundation or the dam body, the precursor of seepage damage can be found in time, and the importance of the seepage water pressure monitoring is self-evident. After the dam is built, the operation period of the dam is dozens of years or even hundreds of years, the osmometer embedded or arranged in the dam is used as an ear for monitoring the operation safety condition of the dam, if the dam fails or malfunctions, the accuracy and the reliability of the monitoring result are directly influenced, even the working state of the dam seepage-proofing body is misjudged, and the long-term stability of the dam seepage-proofing body is more prominent.
The osmometer is mainly composed of 3 parts of a pressure sensing component, a vibrating wire sensing component and a leading-out cable sealing component. The induction part of the osmometer consists of permeable stone and an induction plate. The main parts are all made of special steel. The standard permeable stone is made of sintered stainless steel with 50-micron pores and has good water permeability. The working principle is as follows: the permeating water flows through the permeable stone from the water inlet and acts on the elastic membrane to cause the deformation of the elastic membrane and sense the change of the pressure.
The long-term stability of the osmometer directly affects the lifetime and reliability of the instrument. Most of the reasons for the failure of the osmometer are that the instrument is soaked in natural water for a long time, fine-particle soil, impurities, microorganisms and precipitates of chemical substances in water are adhered to the surfaces of the permeable stone and the elastic membrane of the sensing part, and the osmometer is blocked by the sensing part and fails over time.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a modified is used for monitoring hydraulic structure seepage pressure's osmometer, its is rational in infrastructure, can guarantee the long-term stability that the osmometer used, improves monitoring data's accuracy, life-span and reliability that improve the instrument and use.
The purpose of the utility model is realized like this: the utility model provides a modified is used for monitoring hydraulic structure seepage flow water pressure's osmometer, including burying underground or arranging the inside osmometer in dam in, the structure of osmometer is setting up the leading-out cable in the upper portion of sensor main part, the lower part at the sensor main part is setting up the forced induction part, the forced induction part comprises permeable part and tablet, sealed rigid coupling is on the forced induction part of sensor main part lower part liquid bag device, the liquid bag device contains the forced induction part, be full of the liquid that does not have the corrosiveness in the liquid bag device, and the exhaust air, make the forced induction part all soak in the liquid bag device in the liquid bag of non-corrosiveness.
The utility model discloses locate installation liquid bag device at osmometer head (forced induction part), the bag is flexible, it is sealed, corrosion-resistant material makes (similar balloon), its inside pure water of a certain amount of filling or to the liquid that osmometer response part long-term contact does not have the influence, insert osmometer response part in the liquid bag, the unnecessary air of discharge, make response part all invade the bubble in the bag in liquid, natural water and osmometer contactless behind the installation osmometer, the osmotic pressure of natural water passes through the liquid bag simultaneously and acts on the osmometer, in order to ensure the long-term stability that the osmometer used.
The utility model discloses it is rational in infrastructure, guaranteed the long-term stability that the osmometer used, improved monitoring data's accuracy, improved life-span and the reliability that the instrument used.
