Description

Apparatus for observing underwater}

The present invention relates to an underwater observation device, and more particularly, to an underwater observation device capable of observing underwater plankton without being affected by water currents.

Red and green tides and sudden influx of warm or cold water zones are factors that have a significant impact on the aquatic ecosystem and water quality around the farm.

Red and green algae are phenomena in which the color of water changes due to abnormal mass reproduction of plankton such as flagellates and algae. These red and green algae phenomena greatly affect aquatic ecosystems and water quality by causing water decay, causing mass death of farmed fish and shellfish, and increasing water purification costs.

In addition, the sudden inflow of a hot water zone or a cold water zone causes an abnormal water temperature phenomenon in which the water temperature changes rapidly, which can have a significant effect on the growth and activity of fish and shellfish in the farm, and in severe cases, can cause shock death of fish and shellfish.

If the occurrence of factors that significantly affect the aquatic ecosystem and water quality can be predicted in advance or observed and responded to at an early stage, the resulting damage and restoration costs can be minimized.

Red tides and green tides are caused by a rapid increase in the number of plankton in water, and the inflow of hot water zones or cold water zones accompanies changes in the density or population of plankton due to changes in nutrient concentrations.

Therefore, in order to predict or initially observe the occurrence of these factors, a method of observing the type and density, motility, color, fish species, and aquatic environment of aquatic plankton can be used.

Conventionally, an underwater observation device equipped with an observation camera has been used to observe underwater plankton, fish species, and the underwater environment. However, since the conventional underwater observation device directly observes the underwater environment by exposing the camera to the water, it has been greatly affected by the water flow.

In particular, since plankton floating in water is small in size and can be greatly fluctuated by fine water currents, it can very easily deviate from the focal length of the camera. Accordingly, it has been difficult for conventional underwater observation devices to observe and photograph plankton floating in an environment where water currents exist.

That is, the conventional underwater observation device is not suitable for observing surface plankton where the water flow is large or the direction changes rapidly, and has been mainly used to observe plankton in the deep region where the water flow is little or does not change.

Therefore, there has been an urgent need to develop an underwater observation device capable of observing plankton floating in the water without being affected by the water current even in the surface layer where the size and direction of the water current rapidly change.

The present invention is to solve the above problems, and an object of the present invention is to provide an underwater observation device capable of observing plankton floating in water without being affected by water currents.

Referring to FIG. 6, the operating part of the underwater observation device according to an embodiment of the present invention includes a third body 30, a first sealing member 32, an electromagnet 34, an operating rod 36, and a magnetic body 37. And it may be made of an elastic member (38).

As previously seen, the third body 30 may be formed in a hollow cylinder shape. At this time, the front surface of the third body 30 may be closed, and a hole may be formed on the rear surface.

The operating rod 36 may be formed of a rod-like member extending forward and backward, and a front end may be inserted into the third body 30 . At this time, the operating rod 36 may pass through the rear surface of the third body 30 through a hole formed in the rear surface of the third body 30 .

A first sealing member groove 31 may be formed on the inner circumferential surface of the hole formed on the rear surface of the third body 30 to the outside. A first sealing member 32 may be installed in the first sealing member groove 31 .

For example, the first sealing member 32 may be a rubber ring. The first sealing member 32 is to perform a function of preventing water from entering into the third body 30 through a gap between the outer circumferential surface of the operating rod 36 and the inner circumferential surface of the hole formed on the rear surface of the third body 30. can

A magnetic material 37 may be coupled to the front end of the operating rod 36 . The magnetic material 37 may refer to an object that is magnetized in a magnetic field. For example, the magnetic body 37 may be made of a magnet.

An electromagnet 34 may be installed on the rear surface of the inner surface forming the inner space of the third body 30 . The electromagnet 34 may refer to an object that is magnetized when current flows and loses magnetic properties when current does not flow.

An elastic member 38 may be installed between the electromagnet 34 and the magnetic body 37 . For example, the elastic member 38 may be made of a spring. One end of the elastic member 38 may be connected to the electromagnet 34, and the other end may be connected to the magnetic body 37.

The elastic member 38 may provide a force (elastic force) to pull the electromagnet 34 and the magnetic body 37 closer to each other or push the electromagnet 34 and the magnetic body 37 away from each other by using elasticity. . As a result, the electromagnet 34 and the magnetic body 37 can maintain a predetermined distance in a normal state in which no external force is applied to the elastic member 38 . For example, the normal state of the elastic member 38 may be a state in which the magnetic body 37 is located at the foremost position inside the third body 30 .

Of course, the elastic member 38 may be formed so that the magnetic body 37 does not reach a normal state even when the third body 30 is located at the foremost position. At this time, the elastic member 38 may provide an elastic force pushing the magnetic body 37 forward. One side of the magnetic body 37 is supported by the inner wall of the third body 30, so that the third body 30, the elastic member 38, the electromagnet 34 and the magnetic body 37 may maintain a balance of force. .

Referring to (a) of FIG. 6 , the control unit may allow current to flow through the electromagnet 34 by controlling a current control means (not shown) capable of flowing current through the electromagnet 34 . A mutually attractive attraction (magnetic force) may be applied to the electromagnet 34 and the magnetic body 37 through which current flows.

The attractive force between the electromagnet 34 through which the current flows and the magnetic body 37 can overcome the elastic force and move the magnetic body 37 toward the electromagnet 34 . By this, the operation rod 36 can move backward.

Referring to (b) of FIG. 6 , the control unit may prevent current from flowing through the electromagnet 34 by controlling a current control unit capable of sending current to the electromagnet 34 . The electromagnet 34 in which current does not flow loses magnetism, so that an attractive force (magnetic force) may no longer be applied between the electromagnet 34 and the magnetic body 37.

In order to return to a normal state, the elastic member 38 may apply force (elastic force) to the electromagnet 34 and the magnetic body 37 to separate the electromagnet 34 and the magnetic body 37 from each other. By this, the operating rod 36 can move forward.
