Description

UNDERWATER MEASUREMENT DEVICE FOR VERTICAL PROFILING OF WATER COLUMN

The present invention relates to an underwater measuring device for continuous vertical observation of the vertical structure of the ocean, and more particularly, it is possible to continuously observe the physical state of seawater that changes in time and space, that is, the environmental information of the underwater for a long time continuous The present invention relates to an underwater measuring device for continuous vertical observation of vertical structures in the ocean.

In recent years, as the ocean is expected to be a living place for the future of humanity, many efforts are being made to discover the characteristics of the ocean.

This ocean is changing in time and space like the atmosphere. In particular, the ocean changes, which account for 70% of the world, are leading to environmental changes across the globe. Satellite, Research Vessel, Observation Buoy, Observation Tower, Bottom Mooring System, Wireless Drift Buoy, Unmanned Underwater Vehicle, etc. are used.

At this time, a system on which an exploration sensor is mounted is called a platform, and is largely classified into measurement of the Euler method and the Lagrangian method according to the observation method. The Euler method is a method of observing the physical characteristics of the sea water passing through one vertex in a time series, such as a marine observation buoy, an ocean observation tower, and a seabed mooring system. Lagrangian is a platform where the platform itself moves through the ocean and observes the state of the sea, such as research ships, radio drift buoys, and unmanned underwater probes.

In particular, various unmanned platforms are used to observe changes in seawater's vertical space. Traditionally, it was common to attach sensors to mooring lines connecting sea level and sea bottom at certain intervals to perform observations for a certain period of time (aka CTD sensor chain). Nowadays, a vertical continuous profiler has been developed that measures the marine environment in vertical space by repeating the operation of lowering and raising the observation sensor to a certain depth without using mooring lines. However, on the contrary, a device that achieves the same effect by installing an underwater winch on the sea bottom and causing the sensor to float or roll up to the sea level is also utilized. In addition, vertical continuous observers using electric winches do not have a smooth winch operation at high tides where the angle between the underwater winch and the cable is not an effective angle. In addition, the raw material based on the electric motor requires a large power consumption to start, there is a difficult maintenance.

On the other hand, the underwater measurement device equipped with the buoyancy converter disclosed in the Republic of Korea Utility Model No. 20-0379866 (notice date: 2005.03.24) as a prior art floats randomly by the current current and performs vertical reciprocating movement. At this time, the mounted sensor performs the observation, and when it reaches the designated time, it floats on the sea surface and sends the observation information to the base station. As the name suggests, satellite floats float in the ocean currents, making it impossible to perform observations of the desired point.

The Underwater Glider, developed to explore the desired vertical space, improves the satellite Argo float by adjusting buoyancy to move seawater vertical space up and down. The underwater glider is designed to dynamically move and control the viewing platform to a user-specified position by attaching wings to the satellite board. In particular, the operating mode of the underwater glider, which does not use a propeller and fly at a certain slope with only a buoyancy engine, is suitable for realizing long-term continuous observation of a specific space. In the case of underwater glider, the buoyancy engine is minimized by using a buoyancy engine instead of the motor engine used by the general underwater unmanned body, and it is applied to marine observation by focusing on vertical movement rather than horizontal movement. However, satellite floats and underwater glider using only the buoyancy engine has a problem that can not be used in the South Sea or the West Coast where the current is strong due to low self speed (up to 2 knots) at the place where the tidal current is strong or low depth.

In the following description of the present invention, the well-known functions or constructions are not described in order to simplify the gist of the present invention.

In the accompanying drawings, Figure 1 is a schematic diagram showing an underwater measuring device for vertical vertical continuous observation of the ocean according to the invention, Figure 2 is a vertical vertical continuous observation of the ocean according to the invention shown in FIG. It is a schematic block diagram showing a control unit for controlling the underwater measuring device for. 3A and 3B are schematic views showing an operating state of the underwater measuring apparatus for vertical vertical continuous observation of the ocean according to the present invention shown in FIG. 1, and FIG. 4 shows the movement of the buoyancy body shown in FIG. It is a graph.

1 to 4, the underwater measuring device for vertical vertical continuous observation of the ocean according to the present invention is configured to enable vertical vertical continuous observation of the ocean. That is, the buoyancy body 30 in which the observation sensor unit 40 is installed is freely moved about the fixing unit 20 according to the current or current while maintaining the state connected with the fixing unit 20 by the connecting line 50. While repeatedly moving in the vertical direction by the buoyancy engine 32, the observation sensor unit 40 continuously observes the vertical space of the ocean to obtain marine information.

More specifically, it is as follows.

Underwater measuring apparatus for vertical vertical observation of the vertical structure of the ocean according to the present invention includes a weight portion 22 is installed on the sea bottom, and the fixing portion 20 consisting of an anchor 24 connected to the weight (22) do. The weight 22 is a heavy material for supporting the buoyancy body 30, which will be described later, and is made of a metal material, cement, or the like, which can sufficiently support the buoyancy body 30 by the buoyancy. In addition, the anchor 24 is connected to the weight 22 and the chain, etc., and prevents the position of the weight 22 from being changed.

The buoyancy body 30 is equipped with a buoyancy engine 32 configured to selectively generate positive buoyancy, neutral buoyancy and negative buoyancy by adjusting buoyancy with a power supply 34, and observe for obtaining various information of the ocean. It has a certain shape so that the sensor unit 40 is built in.

This buoyancy body 30 includes a cylindrical or oval hollow housing 31.

A vertical wing 31A and a horizontal wing 31B are provided on the outer peripheral surface of the rear side of the housing 31. The vertical wing 31A and the horizontal wing 31B are for the housing 31 to maintain a stable posture even in the current or the current. And, one end of the housing 31 is provided with a connecting portion 36 for connecting the connecting line 50 to be described later. The connection part 36 is provided with a tension force sensor 36A, the tension force sensor 36A is a connecting line 50 for connecting the fixed portion 20 and the buoyancy body 30 in the sea where the buoyancy body 30 flows. ) To detect a constant tensile force (a drag force acting on an algae or an ocean current) caused by algae or currents. That is, there is always a constant tensile force in the connecting line 50 by the drag on the current or current, if the tensile force is continuously detected below the set value from the tensile force sensor 36A, this buoyancy body 30 and the connecting line 50 ) To determine that the buoyancy engine 32 is switched to the emergency mode to generate the maximum buoyancy so that the buoyancy body 30 rises to the surface. The loss of the buoyancy body 30 can be prevented by such a tension force sensor 36A.

The above-described buoyancy body 30 is provided with a pressure sensor 33A and an acceleration sensor 33B for checking the buoyancy state. The pressure sensor 33A and the acceleration sensor 33B are provided in a part of the housing 31 (in this embodiment, the front region) to detect water pressure and to detect movement so that the buoyancy body 30 floats due to buoyancy. It detects buoyancy such as sinking. That is, when the pressure is detected from the pressure sensor 33A and the movement is detected by the acceleration sensor 33B, a voice buoyancy is generated, which means that the buoyancy body 30 sinks, and from the pressure sensor 33A. When the pressure is detected to be lowered and the movement is sensed by the acceleration sensor 33B, positive buoyancy is generated, which means that the buoyancy body 30 is rising.

On the other hand, the buoyancy engine 32 is installed inside the front side of the housing 31, and the observation sensor unit 40 is installed inside the rear side.

The buoyancy engine 32 is installed in the buoyancy space 32A of the housing 31 and is supplied with power from the piston 32B for varying the volume of the buoyancy space 32A and the power supply unit 34, so that the buoyancy is negative. It comprises an actuator 32C for advancing and retracting the piston 32B so as to adjust neutrally and positively. The buoyancy engine 32 changes the volume of the buoyancy space 32A by the actuator 32C to move the piston 32B forward and backward, so that the buoyancy body 30 has negative buoyancy, or neutral buoyancy or positive buoyancy. To have. For example, when the piston 32B moves forward, the volume of the seawater in the buoyancy space 32A is increased and the volume increases, and when the piston 32B moves backward, the volume of the seawater flows into the buoyancy space 32A. This decrease has a structure in which negative buoyancy occurs.

The buoyancy engine 32 may have a variable buoyancy space 32A. In other words, the flexible variable member configured to expand in the forward movement of the piston 32B and to decrease in volume as it moves backward may form the buoyancy space 32A.

In addition, the buoyancy engine 32 may be configured to generate and discharge a gas to generate a positive buoyancy or negative buoyancy.

Meanwhile, the buoyancy body 30 is provided with a controller 90 for controlling the buoyancy engine 32, the power supply unit 34, and the observation sensor unit 40. The control unit 90 not only generates a control signal necessary for the operation of the buoyancy body 30, but also transmits marine information detected from the observation sensor unit 40 to the land control station 70 through wireless communication, and the land control station. Receiving a control signal transmitted from the 70 to control the movable portion of the buoyancy body (30).

The control unit 90 transmits the state information of the buoyancy body 30 and the observation information detected from the observation sensor unit 40 to the land control station 70 by wireless communication, and the floating time, win, It is configured to receive a control signal for controlling the descending speed, the maintenance of the surface injury for recovery and the control signal for controlling the observation interval of the observation sensor unit 40 from the land control station 70 through wireless communication. At this time, the control unit 90 is a component of the wireless communication unit 92 for transmitting information and receiving a control signal, any one selected from a high-frequency (VHF) modem, a wireless Internet protocol (WiFi), a satellite communication modem And a modem and an antenna 80. In addition, the controller 90 compares the data of the depths acquired from the pressure sensor 33A and the acceleration sensor 33B with previously stored depths, so that the buoyancy engine 32 operates only at the shallow depth value and the deep depth value set by the user. When the buoyancy body 30 descends to negative buoyancy and reaches a predetermined deep depth value, the buoyancy engine 32 operates to generate positive buoyancy, and the buoyancy body 30 rises to positive buoyancy. When the predetermined shallow depth value is reached, the buoyancy engine 32 operates to generate negative buoyancy.

In addition, the power supply 34 for supplying power to the controller 90 and the buoyancy engine 32 is composed of a battery. Such a battery may be applied in various structures and types.

In addition, the controller 90 may include a data processor for processing input data, an analog / digital converter for converting an analog signal into a digital signal, a microcomputer, and the like, and determine the position of the buoyancy body 30. It further includes a GPS, a memory for storing data, and a timer. In addition, specific configurations for driving the buoyancy engine 32, receiving, processing, storing, and transmitting the signals sensed by various sensors are further provided.

On the other hand, the connecting line 50 for connecting the weight 22 and the buoyancy body 30 of the fixing portion 20 is buoyancy body 30 is supported by the weight weight 22 and the weight around the weight 22 To move freely around, the buoyancy body 30 to sink and float to repeat the operation. That is, it is composed of a rope, a chain, a wire or the like to connect the weight (22) and the buoyancy body (30).

The connecting line 50 is preferably to have a material and structure that is not affected by algae or currents. Then, the connecting line 50 is configured to have a length of 2 to 4 times, preferably 3 times the maximum depth of the sea area where the weight (22) is installed. This is to allow the buoyancy body 30 to move around or move up and down freely around the weight weight 22 by the current or the current.

On the other hand, the lower end of the connecting line 50 and the weight portion 22 connecting portion of the fixing portion 20 is provided with a rotating ring 60 (aka: swivel or cooking claw) for preventing the twisting of the connecting line 50, Rotating ring 60 is installed between the upper end of the connecting line 50 and the connecting portion provided on the buoyancy body 30, that is, between the connecting unit 36 and the connecting line 50 to prevent the twisting of the connecting line 50. These rotation rings 60 are buoyant body 30 is raised, lowered, and moving around the weight 22, to prevent the connecting line 50 is twisted, buoyancy body 30 to lift the weight (22) In order to freely move around the weight (22) in accordance with the current or current to the center.

Referring to the operation of the underwater measuring device for vertical vertical continuous observation of the ocean according to the present invention configured as described above are as follows.

The anchor 24 is installed on the sea bottom to obtain information, and the anchor 24 and the weight 22 are connected by a chain.

Subsequently, after coupling one side of the rotary ring 60 to the connection portion of the weight (22), the other side is firmly coupled to one end of the connecting line (50). Then, after the other rotation ring 60 is coupled to the connection portion 36 of the buoyancy body 30, the other end of the connecting line 50 (the lower end toward the sea bottom) is coupled to the other side of the rotation ring 60. .

In this process, the buoyancy body 30 is bound to the fixing part 20 by the connecting line 50, but can move freely around the fixing unit 20 within the range allowed by the connecting line 50, positive It can rise by buoyancy or descend by voice buoyancy.

In addition, the buoyancy body 30 is in a state of being constrained to the fixing part 20 while moving like an underwater kite by water or current.

On the other hand, the control unit 90 receives the control signal from the land control station 70 through the wireless communication unit 92. For example, when the buoyancy body 30 is on the surface or near the water surface due to the positive buoyancy, when the operation start signal is received from the land control station 70, the control unit 90 first, the power supply unit 34 Power is supplied to the buoyancy engine 32 from the actuator 32C to advance the piston 32B.

In this operation, the buoyancy space 32A decreases in volume, so that a negative buoyancy is generated and the buoyancy body 30 sinks. At this time, since the buoyancy body 30 is restrained by the fixing unit 20 by the connecting line 50, the buoyancy body 30 does not depart from the range allowed by the connecting line 50.

On the other hand, when the buoyancy body 30 is settled near the sea floor by the above-described process, the control unit 90 receives the pressure and movement detection signals detected by the pressure sensor 33A and the acceleration sensor 33B to the buoyancy body ( After it is determined that 30) continuously descends in the negative direction, and it is detected that the buoyancy body 30 descends to the negative buoyancy and reaches a predetermined deep depth value, the buoyancy engine 32 raises the actuator 32C. To actuate the piston 32B to generate positive buoyancy. Therefore, the buoyancy body 30 rises again. When it is detected by the pressure sensor 33A and the acceleration sensor 33B that the buoyancy body 30 has risen by positive buoyancy and has reached the predetermined shallow depth value by this operation, the control unit 90 controls the buoyancy engine 32. This again acts to generate negative buoyancy.

At this time, the control unit 90 determines that the buoyancy body 30 sinks or floats to the set position based on the pressure value and the movement value detected by the pressure sensor 33A and the acceleration sensor 33B, and the buoyancy body 30. Since the buoyancy engine 32 is controlled to operate only when the position of the set shallow depth value and the deep depth value is reached, it is possible to save power of the power supply unit 34.

That is, the operation of the buoyancy engine 32, which occupies most of the power consumption, is performed only at the position of the shallow depth value and the position of the deep depth value. It is to minimize. This is possible because the buoyancy body 30 is constrained by the connecting line 50 so that the buoyancy engine 32 does not have to operate continuously accordingly without ever leaving a certain range.

This operation differs from using a motor (actuator to change buoyancy) continuously while the prior art buoyancy devices or unmanned probes are moving, but only when the target depth (maximum or minimum depth) is reached. By activating, power consumption can be minimized.

In this operation, the buoyancy body 30 repeatedly performs the rising and falling in the state of being restrained by the connecting line (50). That is, FIG. 4 is a graph showing the change of the pressure sensor 33A obtained by the rising and falling of the buoyancy body 34 with respect to the time axis. As shown in FIG. 4, the buoyancy body 30 is vertical in water. You will exercise repeatedly. In addition, as shown in FIG. 3B, even if the current is changed, the current is constrained to the connecting line 50 so that only the direction is changed and the vertical movement is repeatedly performed. In addition, since the buoyancy body 30 is constrained by the connecting line 50, the buoyancy body 30 can freely move in any direction by algae or currents within the range allowed by the connecting line 50.

On the other hand, as a result of analyzing the signals detected by the pressure sensor 33A and the acceleration sensor 33B, if there is no change in the pressure, the movement is not detected, it can be seen that the neutral buoyancy occurred. That is, as long as the external force does not reach, the buoyancy body 30 may determine that the neutral buoyancy is stabilized when there is no pressure change or position change at any depth. In this case, the controller 90 operates the buoyancy engine 32 to generate negative buoyancy or positive buoyancy.

The rising and falling speed of the buoyancy body 30 can be adjusted according to the magnitude of the positive and negative buoyancy centered on the neutral buoyancy.

On the other hand, when the buoyancy body 30 repeatedly raises and lowers in the above-described process, the observation sensor unit 40 acquires marine information. For example, environmental information in water including water depth, water temperature, salinity, chlorophyll amount, turbidity, transparency, density, sound velocity, reverberation sound, detection time, and the like are acquired. The controller 90 processes and stores the data sensed by the observation sensor 40.

Subsequently, when the buoyancy body 30 rises, the control unit 90 transmits the state information of the buoyancy body 30 and the underwater environmental information detected by the observation sensor unit 40 through the wireless communication unit 92 through the land control station 70. To send). That is, when the buoyancy body 30 rises and the vertical wing 31A is exposed on the surface of the water, the data is directly transmitted to the land control station 70 through the antenna 80 provided in the vertical wing 31A, or the satellite or the like. It is transmitted to the land control station 70 through.

Therefore, the land control station 70 can obtain the state information of the buoyancy body 30 itself and the marine underwater information transmitted from the buoyancy body 30.

On the other hand, when the buoyancy body 30 is normally injured or abnormally injured, the position of the buoyancy body 30 is grasped by GPS.

5A and 5B are partially enlarged perspective views and cross-sectional views showing another embodiment of the power supply unit shown in FIG. 1.

As shown in FIGS. 5A and 5B, another embodiment of the power supply unit 34 may be provided outside the vertical wing 31A, the horizontal wing 31B, or the housing 31 to generate power while rotating by a bird. It is the same as the above-described embodiment except that the tidal current generator 100 including the turbine 110 is included.

That is, the tidal current generator 100 includes a cylindrical case 120 to accommodate the turbine 110 therein and rotate the turbine 110 while the tidal flow is introduced without interference and passes at a high speed. The case 120 is hollow, and gradually narrows from the inlet region inner circumferential surface 122 to the central region inner circumferential surface 124, and is widened again from the center region inner circumferential surface 124 to the outlet region inner circumferential surface 126. As such, since the inner circumferential surface of the case 120 is formed in a structure for speeding up the flow of the fluid, the rotational speed of the turbine 110 may be increased, thereby improving power generation efficiency.

And, the power generated by the tidal current generator 100 is preferably configured to be stored in the rechargeable battery.

As described above, since the power supply unit 40 is composed of the algae generator 100 generating power using algae or currents, it is not necessary to replace the consumed battery, or the operation of charging may be deleted.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It is obvious to those who have. Accordingly, it should be understood that such modifications or alterations should not be understood individually from the technical spirit and viewpoint of the present invention, and that modified embodiments fall within the scope of the claims of the present invention.
