Краткое описание чертежей.  A brief description of the drawings.
На фиг.1 представлен общий вид измерительного блока аквариумного датчика уровня воды и поплавка.  Figure 1 presents a General view of the measuring unit of the aquarium water level sensor and float.
На фиг.2 представлен общий вид сигнального блока аквариумного датчика уровня воды.  Figure 2 presents a General view of the signal unit of the aquarium water level sensor.
Аквариумный датчик уровня воды содержит два блока измерительный 1 и сигнальный 2, которые могут быть выполнены одинаковыми по форме, а также поплавок 3, в центральной части которого установлен постоянный магнит 4. В центральной части измерительного блока 1 выполнена выемка 5 в виде параллелепипеда, на нижней грани выемки 5 выполнено 2 отверстия 6. В нижней части измерительного блока 1 расположен магнит 7, при этом в сигнальном блоке 2 расположен ответный указанному магниту 7 геркон 8. Блоки скреплены между собой, по крайней мере, 2 парами магнитов 9 и 10, которые расположены в одинаковых местах блоков 1 и 2 противоположными полярностями друг к другу. В верхней части сигнального блока 2 установлен ответный магниту 4 геркон 11.  The aquarium water level sensor contains two measuring units 1 and signal 2, which can be made identical in shape, as well as a float 3, in the central part of which a permanent magnet 4 is installed.

Технический результат - усовершенствование конструкции держателя датчика уровня воды достигается за счет того, что корпус датчика разделен на два блока измерительный 1 и сигнальный 2, которые скреплены между собой, по крайней мере, 2 парами магнитов 9 и 10, которые расположены в одинаковых местах блоков 1 и 2 противоположными полярностями друг к другу. Конструкция крепления датчика позволяет располагать его на Г-образных стенках, стенках с загнутым верхом или на выгнутых (сферических) стенках аквариума, за счет этого достигается технический результат - расширение области использования датчика уровня воды. EFFECT: improved design of the holder of the water level sensor is achieved due to the fact that the sensor housing is divided into two measuring units 1 and signal 2, which are fastened together by at least 2 pairs of magnets 9 and 10, which are located in the same places of the blocks 1 and 2 opposite polarities to each other. The design of the sensor mount allows you to place it on the L-shaped walls, walls with a curved top or on the curved (spherical) walls of the aquarium, due to this a technical result is achieved - expanding the scope of use of the water level sensor.
Датчик уровня воды работает следующим образом.  The water level sensor operates as follows.
Первоначально в выемку 5 измерительного блока 1 помещают поплавок 3 с магнитом 4 таким образом, что в выемке 5 поплавок 3 размещен с возможностью совершения вертикальных поступательных движений. После этого измерительный блок 1 помещают в аквариум, а сигнальный блок 2 размещают у внешней стенки аквариума. После этого совмещают два блока и скрепляют их между собой парами магнитов 9 и 10, при этом измерительный блок 1 находится внутри аквариума, а сигнальный блок 2 снаружи аквариума.  Initially, a float 3 with a magnet 4 is placed in the recess 5 of the measuring unit 1 so that the float 3 is placed in the recess 5 with the possibility of vertical translational movements. After that, the measuring unit 1 is placed in the aquarium, and the signal unit 2 is placed at the outer wall of the aquarium. After that, combine two blocks and fasten them together by pairs of magnets 9 and 10, while the measuring unit 1 is located inside the aquarium, and the signal unit 2 is outside the aquarium.
Так как блоки 1 и 2 скреплены друг с другом двумя парами магнитов 9 и 10 через стекло аквариума, тогда возможно отлипание блоков 1 и 2 друг от друга. Для предупреждения подобной ситуации в датчике предусмотрен механизм сигнализации отлипания блоков 1 и 2 друг от друга. Для этого в измерительном блоке 1 расположен магнит 7, а в сигнальном блоке 2 расположен ответный ему геркон 8. При соприкосновении блоков магнит 7 воздействует на геркон 8, который под воздействием магнитного поля замыкает контакт. Как только происходит изменение положения блоков 1 и 2 друг относительно друга происходит размыкание геркона 8, что сигнализирует об изменении положения блоков 1 и 2 друг относительно друга.  Since blocks 1 and 2 are fastened to each other by two pairs of magnets 9 and 10 through the glass of the aquarium, then blocks 1 and 2 can be detached from each other. To prevent a similar situation, the sensor has a signaling mechanism for the detachment of blocks 1 and 2 from each other. To do this, a magnet 7 is located in the measuring unit 1, and a reed switch 8 is located in the signal unit 2. When the blocks touch, the magnet 7 acts on the reed switch 8, which closes the contact under the influence of a magnetic field. As soon as there is a change in the position of blocks 1 and 2 relative to each other, the reed switch 8 opens, which signals a change in the position of blocks 1 and 2 relative to each other.
После установки блоков 1 и 2 начинают наполнять аквариум водой, как только уровень воды в аквариуме достигнет отверстий 6, тогда давление на поплавок 3 начнет расти и он вместе с магнитом 5 начнет подниматься вслед за подъемом уровня воды. Как только поплавок 3 достигнет верхнего уровня выемки 5, тогда произойдет замыкание геркона 11, что будет сигнализировать о достижении контрольного уровня воды, после чего подача воды в аквариум будет приостановлена.  After installing blocks 1 and 2, they begin to fill the aquarium with water, as soon as the water level in the aquarium reaches holes 6, then the pressure on the float 3 will begin to increase and it will begin to rise along with magnet 5 after the rise in water level. As soon as the float 3 reaches the upper level of the recess 5, then the reed switch 11 will be closed, which will signal that the control water level has been reached, after which the water supply to the aquarium will be suspended.
Как только уровень воды в аквариуме уменьшится, поплавок 3 с магнитом 4 устремится вниз вслед за падением уровня воды и произойдет размыкание геркона 11, вследствие чего подача воды в аквариум возобновится.  As soon as the water level in the aquarium decreases, the float 3 with magnet 4 rushes down after the water level drops and the reed switch 11 opens, as a result of which the water supply to the aquarium resumes.
