A system and method for monitoring the height of rubber dam bag

Abstract

The invention discloses a system and method for monitoring the height of a dam bag of a rubber dam. A first static pressure sensor is fixed at the top of the dam bag of the rubber dam to measure pressure of a water level at the top of the dam bag; a second static pressure sensor is fixed on a dam base of the rubber dam to measure pressure of a water level at the bottom of the dam bag; a water tank is stored with an anti-freezing medium and communicates with the first static pressure sensor and the second static pressure sensor through communicating pipes; the first static pressure sensor and the second static pressure sensor are connected with an acquirer; and heights of the dam top and the dam bottom are calculated according to the pressures obtained by measurement of the sensors, so that the height of the dam bag of the rubber dam. By the measurement of a difference between the height of the dam bag and the height of the dam front water level, an overflow water level can be accurately calculated, so that adjustment of the pressure on the rubber dam can be realized, real-time and accurate control over water storage and waterproofing is realized, and safe operation of a dam body is guaranteed. Therefore, a potential risk can be found, and in-time prewarning can be realized, thus effectively increasing the safety monitoring level of the dam body.

Description

technical field [0001] The invention relates to a system and method for monitoring the height of a rubber dam bag. Background technique [0002] With the development of water conservancy construction in my country, the rubber dam is a new type of hydraulic structure that has emerged with the development of polymer synthetic materials. It has the advantages of low cost, short construction period, quick results, and small maintenance. [0003] The rubber dam is mainly suitable for low water head and long-span gate and dam projects. It is composed of high-strength fabric synthetic fiber stress bones and synthetic rubber. It is anchored on the foundation floor to form a sealed bag shape, which is filled with water or air to form a dam. The main feature is that it can be lifted and lowered freely. In the dry season, fill the rubber dam with water, so that the dam body will rise, which can be used for storage and irrigation; in the flood season, water can be pumped out to make th...

Problems solved by technology

However, the height monitoring of rubber dams has always been a problem. The existing mechanical methods, internal and external pressure comparison methods, laser ultrasound and other non-contact methods have many disadvantages, which are not ideal, and are easily affected by factors such as construction difficulty, floating objects, and changes in the height of overflow water. , so it has been relying on manual observation for a long time; however, the height of the rubber dam is an important basis for the real-time adjustment of the upstream and downstream water levels. It is necessary to ensure the safety of flood discharge and also pay attention to the safety of the dam body and dam bag. Therefore, there is an urgent need for a relatively easy-to-construct, simple and flexible, A monitoring technology that is firmly installed, does not block the river course, and can directly measure the height of the dam bag, and can simultaneously collect high-precision, real-time data and intelligently analyze alarms
