1one

Изобретение относитс к геодезичес Кому приборостроению, в частности к Устройствам гидростатического нивелировани , используемых, например, при определении вертикальных деформаций наклонных сооружений.The invention relates to geodetic instrumentation, in particular, to hydrostatic leveling devices used, for example, in determining vertical deformations of inclined structures.

Известен гидростатический нивелир, содержащий измерительную и опорную головки , при этом измерительна головка не содержит отсчетного устройства, а имеет сливное отверстие 11.The hydrostatic level is known, which contains the measuring and supporting heads, while the measuring head does not contain a reading device, but has a drain hole 11.

К недостатку известного устройства относитс малый диапазон измерени превышений .A disadvantage of the known device is the low measuring range of elevations.

Наиболее близким к предлагаемому по технической сущности вл етс устройство дл определени превышений, содержащее систему сообщающихс сосудов , заполненных жидкостью, при этом кажда пара сосудов системы и соедин юпшй их трубопровод установлены горизонтально , а под четным сосудсл каждой пары на одной вертикали с ним расположен сосуд следующей пары, жесткоThe closest to the proposed technical entity is a device for determining elevations, containing a system of communicating vessels filled with liquid, each pair of vessels of the system and their connecting pipeline being installed horizontally, and under even vessels of each pair on the same vertical line is located the next vessel couples tough

С ним соединенный посредством стержн заданной длины, выполненного из материала с малым коэффициентом линейного расширени , датчиков положени уровн жидкости и измерительного блока 2 3,.Connected to it by means of a rod of a given length, made of a material with a low linear expansion coefficient, liquid level position sensors and a measuring unit 2, 3.

Недостатками известного устройства вл ютс сложность конструкции и большое количество измерений, так как уровень жидкости необходимо измер ть в каждом сосуде.The disadvantages of the known device are the design complexity and a large number of measurements, since the liquid level must be measured in each vessel.

Цель изобретени - упрощение конструкции и повышение производительности труда при сохранении точности путем уменьшени количества измерений.The purpose of the invention is to simplify the design and increase productivity while maintaining accuracy by reducing the number of measurements.

Поставленна цель достигаетс тем, The goal is achieved by

IS что сосуды выполнены двухкамерными, при этом верхн камера снабжена труб.-кой дл слива избытка жидкости в нижнюю камеру, основной сосуд, пополн емый жидкостью, установлен в высшей точке IS that the vessels are made of two chambers, while the upper chamber is equipped with pipes. To drain excess liquid into the lower chamber, the main vessel replenished with liquid is set at its highest point.

Claims

20 and is made in the form of two insulated tanks, each of which is connected to the upper chamber of the adjacent vessel, and the sensors for positioning the liquid level are installed in the lowermost chamber of the communicating vessels. The drawing shows simplified construction of the device for determining exceedances in the form of a closed hydrostatic system. The device consists of two-chamber vessels 1, the upper part of which has a tube 2 for draining excess liquid into the lower chamber of the vessel, connecting hoses 3 that are filled with liquid by the main vessel 4 located at a high point, which consists of two insulated tanks, each of which connected to the upper chamber of the nearest vessel, fluid level position sensors 5 installed in the lower chambers of vessels 1 and in vessels of vessel 4. The vessel 1 installed at the lowest point is equipped with a device 6 for draining excess liquid. The device works as follows. Before operation, the main vessel 4 is replenished with liquid. The excess fluid through the tube 2 in the upper chamber from the court 1 flows into its lower chamber. A similar fluid leveling process occurs throughout the system. The excess liquid from the lower vessel 1 is drained through device 6. After the level of the liquid in the systems has stabilized, the height of the liquid column in the lower chambers of vessels 1 and vessel 4 is measured. The excess is calculated using the formula h a-ti, where 11.1 Excess between i -1 and t points, a is a constant known value, equal to the vertical distance from the vessel oonol to the top of the drain tube, lyj, is the height of the liquid column of the bottom chamber i of the vessel. 9 94 Since the conditions of operation of the drain pipes in all vessels are the same, the measurement accuracy does not decrease as compared with the known. The proposed device allows measurements of elevations and vertical deformations of oblique structures, such as ring accelerators of charged particles. The invention The device for determining exceedances, containing a system of communicating vessels filled with liquid and installed at different heights, each of the vessels of the system and the pipeline connecting them horizontally, as well as positioning sensors of the liquid level in the vessels and measuring unit characterized in that, in order to simplify the design and increase the productivity of labor, while maintaining accuracy, by reducing the number of measurements, the vessels are made of two chambers, while the upper chamber equipped with a tube for draining excess liquid into the lower chamber, the main vessel replenished with liquid is installed at its highest point and made in the form of two isolated tanks, each of which is connected to the upper chamber of the adjacent vessel, and the sensors for positioning the liquid level are installed in the lower chamber of communicating vessels .
