Description

Buoy for detecting tidal current with expanded flag type}

According to the present invention, a low-cost handheld GPS transmitter is used as the GPS transmitter while installing a deployment plate in which four floating wings are arranged in a cross shape at the lower side of a sealed case in which a GPS transmitter and a battery and a flashing light are built. The present invention relates to a flat plate side flow buoy, which is very simple in structure, inexpensive to manufacture, is not easily caught by obstacles, and has excellent visibility for recovery work.

Generally, the sea current refers to the flow of seawater that flows at a constant speed in a certain direction.However, by understanding the currents flowing in coastal waters, it is possible to predict changes in weather conditions such as typhoons and tsunamis and changes in the marine environment in advance. In recent years, the value of its use has been increasing, such as the use of fisheries that move along with currents, which are used as basic data for fishing.

As a method of measuring the ocean currents in coastal waters of Korea, a method using a GPS-equipped side flow buoy is known. The GPS-equipped side flow buoys are transported to a nearby sea by using a vessel, By floating the sidestream buoys to measure piggybacking, the path of the sidestream buoys along the sea current is measured for a period of about 15 to 30 days or more.

As a requirement of the side flow buoy used for measuring currents as described above, it is necessary to flow smoothly along the flow of currents without being easily caught by various obstacles in coastal areas such as aquaculture facilities. Regardless of this, the location of the ship can be easily determined by the naked eye to prevent collision with small ships, and the recovery work must be easily performed.

However, the conventional side buoys usually have a rod shape, and in order to secure visibility, most of them are used by attaching a separate flag to the side buoys, so that the side buoys are easily exposed to various obstacles in coastal waters such as aquaculture facilities. As well as the problem occurs, there is a problem causing a lot of trouble in the current measurement measurement by the side flow buoy caught by the obstacle does not come out via the obstacle.

In addition, the rod-shaped side-stream buoys do not move smoothly to the current flow in their shape and cannot move at a speed similar to that of the current, and because they are easily subjected to additional resistance by the flag fluttering in the wind, it is difficult to measure the current quickly There was a problem, through the small flag during the day, by the flashing light installed with the GPS at night to check the position of the side buoy, there was a problem that the visibility of the side buoy very poor in daytime cloudy weather.

In addition, when the power of the battery for the operation of the flashing light is exhausted, it is impossible to visually check the position of the side buoys at night, which causes a lot of troubles in recovering the side buoys during the day and night. And, for this purpose, when using a large-capacity battery, the side flow portion is increased in weight and volume more than necessary, there was a problem causing many difficulties in the manufacture and handling of the side flow portion.

In addition, as a GPS device applied to the conventional side buoy, the transmitter applied to the side buoy and the receiving terminal carried by the operator were expensive products, and the time difference between day and night was due to the characteristics of the side buoy drifting for about 30 days. Since the remote control parts to operate the flashing lights in accordance with the high price, there was a problem that the manufacturing price of the side flow buoys significantly increased, causing an economic burden.

The present invention has been made to solve the above-mentioned conventional problems, the deployment plate-type side flow portion according to the present invention, four floating wings in the form of a crisscross in the lower side of the sealed case in which the GPS transmitter, the battery and the flashing light are built By installing the deployed deployment plate and using the low cost portable GPS transmitter as the GPS transmitter, the structure is very simple and the production cost is low, and it is not easily caught by various obstacles such as aquaculture facilities. It allows for quick and accurate ocean current measurement by smoothly riding on the current flow, and by using the upper part of the sealed case as a translucent case impregnated with fluorescent or luminous paint, it is possible to collect buoys regardless of day or night. It is a technical task to ensure sufficient visibility is also ensured.

In addition, the deployment plate-type side flow portion according to the present invention, while forming the upper end portion of the sealed case to a transparent portion, while attaching a solar cell for charging the battery or a flashing light control solar sensor on the inner surface of the portion, the same battery It also increases the service life of the flashing part of the side buoy based on the capacity, and enables the operation of the flashing light to be effectively controlled according to the time difference between day and night without using a separate remote control part. Another technical challenge is to provide an economical and practical product that is optimized for ocean current measurement while making manufacturing costs cheaper.

The present invention as a means for solving the above technical problem, the battery, the controller and the GPS transmitter is installed in the inside of the side flow section to measure the path of the current while moving along the current, the sealed case is an upper portion The upper case is formed of a transparent case, the upper case is formed of a transparent case, a flashing light is inserted into the sealed case, and the GPS transmitter is a transmitter used for a portable GPS. The battery is inserted into the lower case of the case, and the GPS transmitter, the flashing light, and the controller are installed together with the circuit wiring board on the upper surface of the battery so as to be covered by the transparent upper case, and the battery inside the upper surface of the upper case.

According to the present invention as described above, by installing a cross-shaped deployment plate that receives the drag of the ocean current on the lower side of the sealed case with a built-in GPS transmitter, the side flow buoy to various obstacles in the coastal waters such as aquaculture facilities It is not easily caught, and the side flow part easily exits through the obstacle, and the development plate allows the side flow part to be smoothly piggybacked on the flow of the current so that it can move at a speed similar to that of the current. Work is possible.

In addition, by forming the upper case of the sealed case as a translucent case impregnated with fluorescent or luminous paint, the position of the side flow buoy can be easily visually checked even in daytime cloudy weather conditions or at night when the flashing light is turned off. As a result, the recovery operation of the side flow buoy can be performed quickly and easily regardless of day or night.

On the other hand, the operation of the flashing light by the solar cell or the solar sensor is properly performed in accordance with the time difference between day and night, so that unnecessary power consumption can be prevented, and the solar cell produced during the day By being able to charge the battery, the service life of the battery is also greatly extended.

Figure 5 (a) and (b) is a side view showing another embodiment of the flat plate side flow portion according to the present invention.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, the deployment plate type side flow unit 10 according to an embodiment of the present invention is connected to a sealed case 4 having a GPS transmitter 5 embedded therein and a lower end of the sealed case 4. It includes a development plate (1) which is installed to be immersed in sea water, and the battery (7), the flashing light (6) and the controller (8) is inserted and installed with the GPS transmitter (5) inside the sealed case (4) Consists of the configuration.

The development plate 1 is installed on the basis of the frame-shaped development plate frame 2 so that a total of four floating wings (3) to form a cross (cross) bar, the development plate frame (2) is a drawing A frame portion intersecting in the form of a crisscross over the horizontal direction and a frame portion extending vertically downward from the center portion of the frame, while the bottom of the sealed case 4 is connected by the connecting rope 1a. Is connected with the side.

The development plate frame (2) is most preferably formed using a plastic material having a specific gravity that is heavier than seawater, the floating wing (3) may be applied to a thin fabric or non-woven fabric or plastic plate, a rather thick material Vinyl film may be applied, if the total specific gravity of the development plate (1) is lighter than sea water, weight may be applied to the bottom of the development plate frame (2) in the vertical direction.

On the other hand, when the development plate frame 2 and the floating wing 3 is the same plastic material, it is preferable to form each part integrally by an injection molding method, and when the deployment plate frame 2 It is preferable to ensure that each floating wing (3) to be firmly assembled by adhesive or fitted along the), but the method of manufacturing the development plate (1) can be applied in various other ways.

In the side flow section 10 according to the present invention, the reason why the four floating wings 3 are arranged in a crisscross shape is that the drag along the flow of the sea current in any direction extends across the deployment plate 1. By more effectively acting, while the side flow portion 10 of the present invention is more smoothly piggybacked on the flow of the current, while the floating blade (3) is caught by various obstacles, while the deployment plate (1) rotates the obstacles It is to be able to easily get out via.

If necessary, for easier obstacle avoidance, the relative rotation of the sealed case 4 inside the bottom portion (see FIG. 2) of the sealed case 4 to which the connecting rope 1a of the deployment plate 1 is connected. A bearing or the like may be installed to allow the floating wings 3 to be three in total, and each floating wing 3 may be arranged in a "s" shape at a 120 degree angle. The use of 5 or more pieces 3) becomes uneconomical in consideration of the function of the development plate 1 and the manufacturing cost at the same time.

In addition, the sealed case 4 is made of a water-tight transparent plastic material to prevent the inflow of sea water, while the light of the flashing light 6 is easily emitted to the outside through the sealed case (4) Although it is preferable to make it possible, it may be a translucent plastic case having a color easily visible to the naked eye for daytime visibility, and a glass case may be applied in addition to the plastic material.

Referring to the structure of the sealed case 4 in more detail on the basis of Figures 1 and 2, the sealed case 4 is a cylindrical upper case 11 and the lower case 12 acting as a lid On the other hand, the lower end of the upper case 11 and the upper end of the lower case 12 is made to be assembled by a screwing method in a state of interposing the sealing ring (11a).

However, the sealed case 4 may be a spherical shape or a rectangular case, in addition to the various types of sealed containers in which watertight treatment is applied, when the sealed case 4 is formed in a rectangular case, the fastening case is fastened. Since the screw fastening method by the part 12a cannot be applied, the case lock of the press method used for a normal container lid should be applied.

Inside the lower case 12 of the sealed case 4, a battery 7 is inserted and installed as a power supply source required for the operation of the side flow section 10, while the GPS transmitter 5 is mounted on an upper surface of the battery 7. And a flashing light (6) and a controller (8) for controlling the operation thereof are installed together with the circuit board (8a), and the upper case (11) connects the GPS transmitter (5), the flashing light (6) and the controller (8). It will serve as a protective cover.

In the sidestream buoy 10 according to the present invention, the GPS transmitter 5 detects the location of people whose behavioral ability is poor, such as infants and the elderly, or grasps the current location of those who enjoy hiking or outdoor activities. For the purpose of doing so, it is most desirable to use a low-cost portable GPS transmitter that is widely used in recent years.

Therefore, the receiving terminal for receiving a signal provided from the GPS transmitter 5 of the current flow section 10 also becomes a low-cost small terminal, but such a receiving terminal can be used in connection with a computer device such as a desktop or a laptop. Even if a low cost portable GPS device is used, it is possible to implement the signal provided from the side streamer 10 into concrete data by various programs.

In addition, as shown in FIG. 2 more clearly, since the sealed case 4 should also be floated to the sea surface with a predetermined buoyancy, the buoyancy space 4a is provided on the lower side of the battery 7. On the other hand, the buoyancy adjustment weight (4b) is inserted into the bottom surface of the lower case 12, in this way to adjust the buoyancy by the weight of the battery (7) without using a separate weight (4b). It is possible to find out.

In the side flow section 10 of the present invention, the components forming another main portion, the upper case 11 constituting the sealed case 4 is formed in a transparent case, inside the upper surface of the upper case 11 Attached and installed a solar cell (Solar cell) (9) that is a charging means of the battery (7), for this purpose, the upper end of the upper case 11 is spherical or curved surface for efficient irradiation of sunlight It is preferable to form with a negative.

In general, the solar cell 9 is a unit of a solar cell, and the number of application and the installation area of the solar cell 9 can be adjusted according to the size of the spherical part of the upper case 11, and bent to an arbitrary shape. It is preferable to use a silicon solar cell, which is a flexible material, or to use a dye-sensitized solar cell or an organic molecular solar cell that can be easily manufactured in a desired shape.

The dye-sensitized solar cell is a solar cell developed to have low energy and high energy efficiency using inexpensive organic dyes and nanotechnology. Since the dye-sensitized solar cell can transmit visible light, the dye-sensitized solar cell can be used as it is on a window of a building or automobile glass. It is a material that can be used, and the manufacturing cost is significantly lower than the conventional silicon solar cell has the advantage of excellent price competitiveness.

In addition, the organic molecular solar cell has the functionality as a light plastic solar cell, because it is manufactured by spraying organic materials on a cheap and freely bendable substrate, it is possible to mass-produce in various shapes, according to technology development If the efficiency is increased, it is expected to be applied to more kinds of electronic devices in the future.

In addition to the silicon solar cell, the dye-sensitized solar cell, or the organic molecular solar cell as described above, if the solar cell is easily deformed in any shape or can be manufactured to the desired shape, the GaAs compound solar cell, the CuInSe2 compound solar cell, It is clear that any kind of solar cell as well as CdTe compound solar cell can be applied.

When the solar cell 9, which is a solar cell, is applied to the upper inner surface of the upper case 11 as described above, the solar cell 9 and the battery 7 are charged with the charging cable 13 as shown in FIG. 3. By connecting, it is possible to produce electric power using sunlight irradiated to the sea level during the day, while the electric power thus produced is charged to the battery 7 via a converter not shown.

As described above, the method of charging the battery 7 through the converter with the power generated from the solar cell 9 is a well-known technique well known in the photovoltaic field, and a wide variety of methods may be applied thereto. It will be omitted, it is most preferable that the converter is built in the battery 7 in the state connected with the charging cable (13).

On the other hand, the solar cell 9 may also have a function of a sensor to prevent the flashing light 6 is turned on during the day, for this purpose, the charge sensing line 14 is extended from the charging cable 13 so that the controller 8 ), It is possible to determine whether the electricity produced by the solar cell 9, that is, day and night judgment in the controller 8, and thus the switch of the flashing light 6 connected to the control line 16a ( 16) The controller 8 controls the operation so that the flashing light 6 does not turn on during the day.

This function can also be achieved by attaching a solar sensor in place of the solar cell 9, but in the case where only the solar sensor is attached, there is a disadvantage in that an additional auxiliary power cannot be charged to the battery 7, which is most preferable. Preferably, the solar cell 9 and the solar sensor are applied at the same time, so that the solar cell 9 produces auxiliary power, while the solar sensor requires more delicate operation. Night judgment.

In the wiring structure shown in FIG. 3, the remaining wirings, ie, the respective wires except for the charging cable 13 and the charging sensing line 14, which connect the solar cell 9 to the battery 7 and the controller 8. 15 and the control line 16a, the switch 16, and the like are most preferably provided in a circuit form on the substrate 8a, and the charging cable 13 and the charge sensing line 14 are provided in the upper case 11. It is desirable to extend along the inner side of the and then contact the substrate 8a at a suitable position.

In the side flow section 10 of the present invention, as another component forming a main portion, the upper case 11 of the sealed case 4 is a translucent case impregnated with a fluorescent paint or a luminous paint. 9) Alternatively, if the solar sensor is attached to the inner surface, the remaining portion except for the portion may be a translucent case impregnated with fluorescent paint or luminous paint.

As described above, when the upper case 11 of the sealed case 4 is formed of a translucent case impregnated with fluorescent or luminous paint, the light of the flashing light 6 is almost prevented from being emitted to the outside through the upper case 11. Without causing, it is possible to easily check the position of the side flow section 10 by the fluorescent paint impregnated in the upper case 11 in cloudy daytime.

In addition, even when the power of the battery 7 is completely consumed and the flashing light 6 is turned off, the position of the side flow section 10 at night is visually determined by using the luminous phenomenon of the luminous paint generated from the upper case 11. The upper case 11 is impregnated with a paint having both fluorescence and luminous function so as to secure both daytime visibility and nighttime visibility. Of course, the outer surface of 12) can be coated with the paint.

FIG. 4 shows another type of development plate 1 that can be used in the present invention, in which floating wings 3 having a rough quadrant shape are applied instead of the square floating wings 3 shown in FIG. 1. This is because when the floating wing 3 of the rectangular shape is applied, the lower edge of each floating wing 3 flutters as the current flows, which may adversely affect the piggybacking of the current. In addition, this structure minimizes this phenomenon and is capable of sufficiently receiving drag caused by currents.

5 (a) and (b) shows the development plate side flow portion 10 according to another embodiment of the present invention, in one embodiment of the present invention connects the sealing case 4 and the deployment plate (1) Instead of using the connecting rope 1a, the sealed case 4 itself is fixedly installed on the upper side of the development plate frame 2, while the center weight 17 is installed at the lower end of the deployment plate frame 2. The other configurations are the same as in the embodiment described above.

According to another embodiment of the present invention, the deployment plate side flow section 10 may completely eliminate the possibility that the side flow section 10 may be caught by various obstacles such as aquaculture facilities by not using the connection rope 1a. In addition, the central weight 17 is to be locked together in the seawater by a predetermined depth to the lower side of the sealed case 4 together with the deployment plate 1, while maintaining the posture of the side flow section 10, the present invention The side flow section 10 is in charge of the function to be able to move more quickly and stably along the current.

In addition, it is preferable to form the closed case 4 of the deployment plate side flow portion 10 according to another embodiment of the present invention having a lower width and a wider case than the closed case 4 according to the embodiment. In this way, it provides a desirable advantage in terms of further improving the day and night visibility by the upper case 11 as well as the stable flow of the side flow (10).

According to the present invention as described above, by installing a cross-shaped deployment plate (1) subjected to the drag of the sea current on the lower side of the sealed case (4) in which the GPS transmitter (5) is built, exists in coastal waters, such as aquaculture facilities The side stream 10 is not easily caught by various obstacles, and the side stream 10 is easily pulled out through the obstacle. It can smoothly ride on the flow and move at a speed similar to that of the current, which enables quick and accurate measurement of the current.

In addition, by forming the upper case 11 of the sealed case 4 into a translucent case impregnated with fluorescent or luminous paint, the side flow section 10 may be used even in daytime cloudy weather conditions or at night when the flashing light 6 is turned off. The position of the eye can be easily confirmed by the naked eye, and thus, the recovery operation of the side flow unit 10 can be performed quickly and easily regardless of day or night.

On the other hand, the operation of the flashing light 6 by the solar cell 9 or the solar sensor is properly performed according to the time difference between day and night, so that unnecessary power waste can be prevented, as well as the solar cell. By being able to charge the battery 7 with electric power produced during the day by (9), the service life of the battery 7 can also be greatly extended.

Therefore, when the battery 7 having the same capacity required for the side flow section 10 is used as a reference, the volume and weight of the battery 7 can be reduced to the maximum, and the flashing light 6 can be adjusted according to the time difference between day and night. It is possible to eliminate the remote control parts to be operated, and by applying a low cost portable GPS to the side flow section 10, the manufacturing cost of the side flow section 10 is very economical and optimized for the measurement of the current flow while It can provide a practical product.
