Изобретение относитс  к эксиериментальной гидромеханике.This invention relates to exertional hydromechanics.

Известны устройства дл  транспортировани  моделей в экспериментальных вакуумных бассейнах, заполненных частично жидкостью, содержащие бассейн с установленным вне его поршневым приводом, св занным проход щим сквозь уплотнение в стенке бассейна тросом с транспортируемой моделью, наход щейс  в бассейне. Однако в них необходима установка специального иорщневого привода.Devices are known for transporting models in experimental vacuum pools partially filled with a liquid, containing a pool with an external piston drive installed connected by a cable passing through the seal in the pool wall with the model being transported in the pool. However, they require the installation of a special worm drive.

Целью изобретени   вл етс  упрощение конструкции устройства.The aim of the invention is to simplify the design of the device.

Дл  этого на стенке бассейна установлен силовой цилиндр, поршень которого св зан с транспортируемой моделью, причем одна полость силового цилиндра сообщена посредством патрубка с вентилем с атмосферой, а друга  - с пространством над жидкостью в бассейне.To do this, a cylinder is mounted on the pool wall, the piston of which is connected with the model being transported, one cavity of the cylinder being in communication with the valve through the branch pipe and the other with the space above the liquid in the pool.

На чертеже показано описываемое устройство .The drawing shows the described device.

В вакуумном бассейне 1 над свободной поверхностью жидкости 2, заливаемой в бассейн , создаетс  пониженное давление по сравнению с атмосферным. Исследуема  модель 3 тонким тросо.м 4, проход щим через уплотнение 5, соединена с поршнем 6, двигающимс  в направл ющей трубе 7. Последн   св зана отвод щим патрубком 8 с верхней полостью вакуу.много бассейна, заполненной разреженным воздухом или другим газом под давленпсм, меньшим чем атмосферное. Нижн   часть направл ющей трубы 7 соединена с ат1мосферой вентилем 9.In the vacuum pool 1, above the free surface of the liquid 2 poured into the pool, a reduced pressure is created compared to the atmospheric one. Investigated model 3 is a fine wire 4 passing through seal 5 and connected to piston 6 moving in guide tube 7. The latter is connected by outlet pipe 8 to the upper cavity of the vacuum basin filled with rarefied air or other gas under pressure. less than atmospheric. The lower part of the guide tube 7 is connected to the atmosphere by valve 9.

Нри открытии вентил  9 на модель 3 через трос действует сила, создаваема  разностью атмосферного давлени  и давлени  в бассейне . Opening the valve 9 on the model 3 through a cable is affected by the force created by the difference in atmospheric pressure and pressure in the pool.
