Description
ществом 6. Щель дл измерени образована в горной породе 7.substance 6. A measurement slot formed in a rock 7.
На фиг, 2 показано расположение измерительного преобразовател 8 соединенного трубопроводом 5 с регистратором 9, Измерительный преобрзователь установлен между контактными поверхност ми 10, св занными с горной породой соединительным веществом .Fig. 2 shows the location of the measuring transducer 8 connected by pipeline 5 with the recorder 9. The measuring transducer is installed between the contact surfaces 10 connected to the rock by a connecting substance.
Две.контактные поверхности 10, установленные на противоположных берегах- щели, образованной в горной породе 7, частично залиты соединительным веществом 6, станов тс частью Массива, подверженного вариаци м напр жений и деформаций и .при перемещении стенок щели перемещаютс вместе с ними. Установленный между контактными поверхност ми мембранный преобразователь представл ет собой герметичную полость, заполненную жидкостью под давлением. Давление в полости прижимает мембраны измерительного преобразовател К контактным поверхност м. Перемещение контактных элементов, св занных с измер емым объектом, ведет к изменению давлени жидкости в измерительном преобразователе Ь и регистрируетс регистратором 8.Two contact surfaces 10, installed on the opposite sides of the slit formed in rock 7, are partially filled with connecting substance 6, become part of the Array, subject to variations of stresses and strains, and moving the slit walls move with them. A membrane transducer mounted between the contact surfaces is a sealed cavity filled with pressurized fluid. The pressure in the cavity presses the membranes of the measuring transducer to the contact surfaces. Moving the contact elements associated with the object being measured leads to a change in the fluid pressure in the measuring transducer b and is recorded by the recorder 8.
Использование предлагаемого изобретени позвол ет вести регистрацию напр жени без помех, обусловленных вли нием шероховатости соединительного вещества, а также позвол ет вести регистрацию напр жений , возникающих в Земле при лунных приливах, что до предложенного изобретени было невозможнымThe use of the present invention allows to register voltage without interference due to the influence of the roughness of the coupling substance, and also allows the registration of voltages occurring in the Earth at lunar tides, which was impossible before the proposed invention
из-за соизмеримости помех с измер емой величиной.due to the commensurability of interference with the measured value.
