Description

По существующему способу KOiMпарирование эхолота с целью установки нул  щкалы при начальной регулировке или определени  на различных глубинах поправки эхолота дл  последующего исправлени  его показаний производ т путем сличени  глубин, показываемых эхолотом , с глубинами, принимаемыми за истинные. При этом за истинные глубины принимают или глубины, измеренные ручным лотом, или полученные при помощи «искусственного дна, т. е. доски, опускаемой на различные глубины под кораблем и используемой дл  отражени  сигнала, направл емого на нее с корабл .According to the existing KOiM method, pairing the echo sounder with the aim of setting zero points at the initial adjustment or determining the echo sounder at different depths for subsequent correction of its readings is done by comparing the depths shown by the echo sounder with the depths taken as true. At the same time, the true depths are either taken as the depths measured by a manual lot, or obtained using an artificial bottom, i.e. a board lowered to different depths under the ship and used to reflect the signal sent to it from the ship.

Компарирование эхолота при помощи ручного лота неудобно потому, что дл  определени  поправок эхолота на разных глубинах, кораблю требуетс  несколько раз сниматьс  с  кор  и переходить с места на место, подбира  нужные глубины.The echo sounder comparing using a manual lot is inconvenient because in order to determine echo sounder corrections at different depths, the ship needs to be removed from the core several times and moved from place to place, selecting the required depths.

Компарирование эхолота при помощи «искусственного дна применимо только до глубин 35-40 м, так как при опускании на большие глубины особенно при волнении мор  и на течении не всегда можно получить отраженный импульс, а следовательно , и поправку эхолота.The echo sounder comparing using the “artificial bottom” is applicable only to depths of 35–40 m, as it is not always possible to get a reflected impulse, and therefore an echo sounder correction, when descending to great depths, especially when the sea is rough and flowing.

Насто щее изобретение имеет целью устранить эти недостатки известных способов компарировани  эхолота, позвол ет получать общие поправки эхолота на глубинах пор дка 100-150 м и состоит в следующем .The present invention aims to eliminate these drawbacks of the known methods of comparing the echo sounder, makes it possible to obtain general echo sounder corrections at depths of the order of 100-150 m and consists of the following.

От эхолота на период компарировани  отключаетс  излучатель (или приемник) и вместо него подключаетс  опускаемый за борт на тросе вспомогательный вибратор, укрепленный в кардановом подвесе с обращенной вверх и параллельной к поверхности уровн  мор  вибрирующей поверхностью.The emitter (or receiver) is disconnected from the echo sounder for the period of comparing, and instead it is connected to the auxiliary vibrator lowered overboard on the cable, fixed in a gimbal with the vibrating surface facing up and parallel to the surface of the level.

Поправка эхолота определ етс  как разность между отсчетом по эхолоту и рассто нием между вибраторами , определ емым по длине вытравленного троса.The echo sounder correction is defined as the difference between the echo sounder reading and the distance between the vibrators, defined by the length of the etched cable.
