Description

underwater media system

[0001] The present invention relates to an underwater media system, and more particularly, to an underwater media system for implementing an image produced underwater at the bottom of a bridge installed on a lake, river, or sea.

[0002] In order to implement an underwater image projected on the bottom of a bridge installed over a lake, river, or sea, a beam projector that projects the image must be located above the water, and a reflector must be located underwater so that the image projected from the beam projector above the water can be reflected in the water.

[0003] The beam projector above the water must maintain a constant spatial position regardless of the shape of the structure to which it is attached.

[0004] The spatial position should be maintained so that the horizontal and vertical deviations relative to the ground are within 5% of the focal length of the beam projector, thereby minimizing the misalignment of edge blending, which allows multiple beam projector images to be displayed as a single image.

[0005] Therefore, there is no problem in cases where the piers or deck of the bridge to which the beam projectors are attached are fixed, as in a normal bridge, but in places where the deck of the bridge moves, such as a suspension bridge, the horizontal spacing between the beam projectors relative to the ground must be maintained constant despite the movement.

[0006] In addition, when the water level fluctuates beyond the allowable range of the beam projector projection distance due to flood or drought, and the image is not properly formed, the position of the beam projector on the water must be changed in proportion to the changed water depth position of the underwater reflector.

[0007] In addition, as the underwater condition changes in turbidity, such as green algae or muddy water caused by flooding, the beam of the beam projector penetrating the water depth is reflected by the underwater reflector, and the image that reaches the viewer's eyes becomes more skewed.

[0008] Accordingly, the distance from the underwater reflector to the water surface should vary depending on the turbidity, such as green algae or muddy water.

[0009] Even in the event of changes in water flow, such as during a flood, the underwater reflector must maintain a constant horizontal position, and in order for the image projected from the beam projector to be stably displayed on the screen, the positional fluctuation of the installed underwater reflector must be within ±5% of the horizontal length and ±5% of the vertical length.

[0010] The underwater reflector should not be visible to the viewer during the day, but should have a very high reflectivity for night projection to produce clear underwater images.

[0011] However, although some technologies for directly implementing images underwater have been disclosed, technologies for installation and operation in places with swaying bridges or fast currents, and technologies for implementing stable images according to changes in the water surface have not been disclosed.

[0041]

[0042] Hereinafter, with reference to the attached drawings, the underwater media system according to the present invention comprises: an image projection means for projecting an image underwater from a pier or pier deck; an image projection means position maintenance device for maintaining an image adjusted as a single image through edge blending SW from images projected from multiple beam projectors; an image projection means vertical position adjustment device for adjusting the distance between the water surface and the image projection means position maintenance device; an underwater reflector frame depth maintenance device for allowing an underwater reflector to maintain a constant depth on the water surface; an underwater reflector frame depth position adjustment device for adjusting the depth position of the water surface and the underwater reflector frame according to changes in conditions such as underwater turbidity; an underwater reflector frame position control device for maintaining a constant position of the underwater reflector frame even according to changes in water velocity and depth and changing the position according to the water depth; an underwater reflector that is not easily visible to the viewer during the day due to its color being similar to that of the water, but is easily visible to the viewer during night projection by adjusting the scattering rate and reflectivity of the underwater reflector. It is characterized by increasing the reflectivity of the underwater reflector that can be increased.

[0043]

[0044] Referring to FIGS. 1 and 3, the image projection means position maintenance device is characterized by being composed of a beam projector attachment housing combination frame (10) and a shock absorber (30, 40).

[0045]

[0046] The beam projector attachment housing combination frame (10) that combines and fixes the housing to which multiple beam projectors are attached is made of a square iron timber.

[0047]

[0048] Referring to Fig. 2, the beam projector attachment housing (20) and the iron square frame are fixed with bolts.

[0049]

[0050] In general, when projecting with a beam projector, when making two or more images into one image, if each beam projector projects, the overlapping part may be misaligned or the light may be strong enough to make the boundary line stand out. The process of naturally composing this part as one screen is called edge blending.

[0051] At this time, if the spacing between the edge-blended beam projectors changes, the edge-blending is broken.

[0052]

[0053] Beam projectors attached to places where the bridge deck moves, such as a suspension bridge, must maintain a gap between the beam projectors to prevent edge blending from being broken, as the beam projectors also move according to the movement of the bridge deck.

[0054]

[0055] As in Fig. 2, when the housing to which the beam projector is attached is attached to the beam projector attachment housing joint frame (10), the spacing between the beam projectors remains unchanged, but when the upper plate, such as the swing bridge, moves, the entire beam projector attachment joint frame moves.

[0056]

[0057] Accordingly, a device is needed to minimize the movement of the beam projector attachment housing combination frame even when the top plate of the suspension bridge moves.

[0058]

[0059] Referring to FIGS. 3 to 5, a device for minimizing movement is composed of an iron or fiber (chemical and natural) wire (30) between the bridge plate and the beam projector attachment frame, and a shock absorbing device (40) that absorbs external force between the wires.

[0060]

[0061] The image projection means vertical position adjustment device (50) is a device for moving the position of the image projection means position maintenance device in the vertical direction.

[0062] The vertical position adjustment device (50) of the image projection means is composed of a power device that pulls or releases a wire (30) connected to the beam projector attachment housing coupling frame (10) of the image projection means position maintenance device.

[0063] The power unit is operated by an electric motor or human power.

[0064]

[0065] In order to obtain a clear image, the underwater reflector located underwater and the beam projector located above the water surface must be located at an appropriate focal length of the beam projector.

[0066] In the case of an underwater reflector attached to a device that automatically maintains a constant depth on the water surface when the water level fluctuates due to reasons such as drought or flood, the distance between the beam projector and the underwater reflector must be maintained constant, so the position of the beam projector must be raised or lowered.

[0067]

[0068] For this purpose, power is required to raise or lower the image projection means position maintenance device, and the image projection means vertical position adjustment device changes the position of the image projection means position maintenance device in the vertical direction through power.

[0069] The combined appearance of the image projection means vertical position adjustment device and the image projection means position maintenance device is as shown in Fig. 5.

[0070]

[0071] The vertical position adjustment device (50) of the image projection means is characterized by being configured with a power device that pulls or releases a wire connected to the beam projector attachment housing joint frame.

[0072] The power unit is operated by an electric motor or human power.

[0073]

[0074] Referring to Fig. 6, the underwater reflector frame depth maintenance device is a device that maintains the depth of a reflector (60) having a mesh structure at a constant level, and is composed of a device (80) that maintains the distance between the underwater reflector frame (70) and the water surface, and a buoy device (90) on the water surface.

[0075]

[0076] Referring to Fig. 7, the underwater reflector frame is a hollow cylinder (70) made of transparent resin such as acrylic or polycarbonate, and is configured as a square or polygonal frame.

[0077]

[0078] Referring to Fig. 8, the underwater screen (60) coupled to the underwater reflector is made of a mesh-shaped material through which water can pass.

[0079]

[0080] Referring to Fig. 9, a side view of an underwater screen (60) coupled to an underwater reflector frame is illustrated.

[0081] In the above drawings 8 and 9, the underwater reflector (60) with a mesh structure ultimately functions as an underwater screen, and is therefore described with the same symbol.

[0082]

[0083] The underwater reflector frame is made of a sealed cylinder made of hollow acrylic or resin to allow buoyancy, and the total buoyancy of the underwater reflector frame should be 10% to 50% less than the weight of the underwater reflector and frame to minimize the size of the buoy.

[0084]

[0085] The total buoyancy of the buoy must be greater than the underwater weight of the underwater reflector frame and the underwater reflector.

[0086] The wire connecting the buoy and the surface reflector frame is made of metal or natural fiber or chemical fiber.

[0087]

[0088] Referring to FIGS. 10 to 13, the underwater reflector frame position control device is composed of an underwater reflector frame position fixing device (see FIG. 11) that fixes the position of the underwater reflector frame, and an underwater reflector frame depth change device (see FIG. 12) that changes the depth position of the underwater reflector frame.

[0089]

[0090] Referring to Fig. 11, the underwater reflector frame and the round ring are connected by wire (110), and the round ring (110) is made of a metal material.

[0091] The underwater reflector frame fixing device consists of three weights (130).

[0092] The weight (130) and the underwater reflector frame are connected by a wire (120), and the material of the wire is made of natural, chemical or metal.

[0093]

[0094] Each weight is configured with a wire length that allows it to be positioned at an equal angle in the water depth.

[0095]

[0096] In order to adjust the length of the wire between the underwater reflector frame and the weight, a metal ring (110) is attached to the underwater reflector frame.

[0097] Three wires (120) connected to each weight pass through a ring and are connected to a power source (140) that adjusts the length of the wires.

[0098]

[0099] The underwater reflector frame depth position adjustment device is

[0100] A device for adjusting the length of a wire connecting a buoy (90) and a frame (70) of Fig. 6, characterized in that the length is adjusted by power or manpower.

[0101]

[0102] Method for increasing the reflectivity of underwater reflectors

[0103] In order to increase the reflectivity of underwater reflectors during the day while not being visible to viewers, and to increase the reflectivity during projection at night, when the water color of the digital photo is between 45 and 70 degrees based on the HSV model color chart, the screen color is composed of HSV 60 degrees, and the method for increasing the reflectivity of the screen is to apply a mixture of 20% gray pearl and 80% transparent pigment to a thickness of 0.1 to 0.2 mm.

[0104]

[0105] When the water color of a digital photo is between 90 and 120 degrees based on the HSV model color chart, the screen color is composed of colors of HSV 100 degrees, and the method of increasing the reflectivity of the screen is to apply a mixture of 20% emerald pearl and 80% transparent pigment with a thickness of 0.1 mm to 0.2 mm.

[0106]

[0107] When the underwater turbidity is 5 to 10 NTU (Nepthelometric Turbidity Unit), the screen color is composed of colors with an HSV of 60 degrees, and the method of increasing the reflectivity of the screen is to apply a mixture of 20% gray pearl and 80% transparent pigment with a thickness of 0.1 to 0.2 mm.

[0108]

[0109] When the underwater turbidity is 10 to 20 NTU (Nepthelometric Turbidity Unit), the screen color is composed of colors with HSV of 60 degrees, and the method of increasing the reflectivity of the screen is to apply a mixture of 10% gray pearl, 10% black pearl, and 80% transparent pigment in a thickness of 0.1 to 0.2 mm.
