Description
Изобретение относится к лаборатор; ному гидротехническому оборудованию и может бь(ть использовано для моделирования потоков, образующихся при < разрушении плотин.The invention relates to a laboratory; hydrotechnical equipment and can be used to model flows generated during the destruction of dams.
Известно устройство для образования потоков, возникающих при разрушении напорного фронта плотин, включающее лоток и затвор с жесткой paмой между ними [1].A device for the formation of flows arising from the destruction of the pressure front of dams, including a tray and a shutter with a rigid frame between them [1].
Недостатком известного устройства является постоянная ширина потока, не изменяющаяся во времени.A disadvantage of the known device is a constant flow width that does not change over time.
Известно также устройство для образования потоков, возникающих при ’’ разрушении напорного фронта плотин, включающее бассейн, лоток и затвор с приводом. Причем затвор имеет сменные диафрагмы. Достоинством этого устройства, по сравнению с описанным, 20 является то, что оно позволяет моделировать потоки любого заданного профиля [2).It is also known a device for the formation of flows arising from the ’’ destruction of the pressure front of the dams, including a pool, a tray and a shutter with a drive. Moreover, the shutter has interchangeable apertures. The advantage of this device, in comparison with the described 20, is that it allows you to simulate the flows of any given profile [2).
Однако оно не позволяет моделиро- __ вать поток при увеличении горизонтального размера прорана в результате разрушения плотины, что значительно уменьшает точность моделирования.However, it does not allow simulating __ flow with an increase in the horizontal size of the aperture as a result of dam destruction, which significantly reduces the modeling accuracy.
Цель изобретения - повышение точности моделирования. 30The purpose of the invention is to improve the accuracy of modeling. thirty
Цель достигается тем, что затвор выполнен из двух щитов со скошенными торцами, установленных в горизонтальных направляющих.The goal is achieved by the fact that the shutter is made of two panels with beveled ends installed in horizontal guides.
На чертеже изображено предлагаемое устройство.The drawing shows the proposed device.
Бассейн 1 и лоток 2 разделены опорными неподвижными щитами 3 и затвором, состоящим из двух подвижных щитов 4, которые с помощью палиспастов 5 и троса 6 соединены с сервоприводом 7 и программно-управляющим устройством 8.The pool 1 and the tray 2 are separated by supporting fixed shields 3 and a shutter consisting of two movable shields 4, which are connected with a servo drive 5 and a cable 6 to a servo-drive 7 and a program-control device 8.
Устройство работает следующим образом.The device operates as follows.
При включении программно-управляющего устройства 8 сервопривод 7 раздвигает щиты 4 с заданной скоростью и происходит истечение воды из бассейна 1 в лоток 2 через проран, об- . разованный скошенными торцами щитов 4When you turn on the program-control device 8, the servo drive 7 pushes the shields 4 at a given speed and water flows from the pool 1 into the tray 2 through the aperture, rev. developed by beveled ends of shields 4
Устройство позволяет производить моделирование потоков, образующихся при разрушении напорного фронта плотин, при любой конфигурации прорана и скорости его развития, а следовательно, с большей точностью моделирование.The device allows simulating the flows generated during the destruction of the pressure front of dams, with any configuration of the proran and the rate of its development, and, consequently, with greater accuracy modeling.
