The present invention relates to a facility installed on the sea to protect the algae power plant, and more specifically, to a facility for protecting the algae power generation facilities from collisions or sticking of floating contaminants having various volumes and masses in the sea where fast algae flows. will be.

The conventional tidal power generation is similar to the hydroelectric power generation method by installing tidal dams in the inner bay with a large tidal gap to block seawater distribution and generating power using a level difference inside and outside the dam generated by the tidal tidal wave.

However, tidal power generation uses the water level difference inside and outside the dam (embankment), so there is a problem in that it is necessary to form a seawall and entail environmental effects.

In order to improve the shortcomings of tidal power generation, recent attempts have been made to produce algae, which is evaluated as an environment-friendly power generation method than tidal power generation. Algae power generation is estimated to be more environmentally friendly than tidal power generation because the tidal power generators for tidal power generation are installed directly in the waterways where strong flow rates occur due to tides.

On the other hand, algae power generation facilities are installed on the sea near the land, and household waste products such as household waste, which are thrown away by the sea, are expected to flow from flocks such as horses, nets, buoys, etc., generated from farms and fisheries. For this purpose, a protective facility should be installed to continuously remove the floating contaminants.

These floats can be divided into cases that can give a big impact on the equipment and cases that can be stuck or wound on the equipment to reduce the performance of the equipment.

In order to prepare for the floats, the facilities according to the present invention each introduced a basic structure and a vibration damper of a frame structure, which will be described later.

In general, a vibration damper is a device for filtering and removing suspended solids floating on the screen by being installed in a drainage pump station, a water supply intake, a related water channel, a sewage treatment plant and a dam in a lower area than the surface of the water.

The damper uses an endless chain 14 to move the rake 13 protruding from the bottom up between the screens when the float floating with the water flow is caught on the screen 11 as shown in FIG. By driving by driving, the suspended matter suspended in the screen 11 is turned over to the discharge conveyor 18 installed on the upper back of the vibration damper.

The vibrator penetrates the H beam through the through-hole 15 formed in the frame 12 attached to both sides of the vibration suppressor, and then uses the anchor to the concrete support 16. It was common to fix and install.

On the other hand, the protection facility according to the present invention is composed of a frame structure consisting of a large pipe, there is a fundamental difference in the support body on which the vibration damper is installed, and the vibration damper installed in the conventional waterway of the conventional land channel is installed in accordance with a constant direction of the water flow Since the direction of the tide is changed in general, the installation method of the general vibration damper of the land could not be applied as it is.

In addition, when installing the vibration damper perpendicular to the direction of the water flow as in the general installation method, the vibration damper could not easily withstand the impact load generated when colliding with the floating float due to the high flow rate, which could easily damage the vibration damper.

As to solve the above problems,

An object of the present invention is to provide a means for protecting the algae power generation equipment and removing the floats from these floats in preparation for various floats.

In addition, an object of the present invention is to configure the protective facility to be suitable for flowing algae in both directions.

It is also an object of the present invention to provide a means for allowing the vibration damper to be installed in the frame structure of the protective facility.

In order to achieve this technical problem,

The algae power generation facility protection facility according to the present invention is installed in the sea (Jacket) is fixed to the ground and consists of a floating water blocking portion installed in accordance with the flow of algae.

In the present invention, the jacket refers to a structure configured to connect a plurality of rod-type or pipe-type supports to form a constant space in which the equipment to be protected can be placed.

Referring to FIG. 3, the jacket is basically embedded in the rock so as to accept the load of the vibration damper and the impact load due to the float, etc. (21A, 21A ', 21B, 21B', 21C, 21C) ') And vertical supports (22B, 22B', 22C, 22C ') installed between the main supports to distribute the load applied to the main support.

In addition, a series of horizontal supports 31 are horizontally installed on the sea surface to connect the main support and the vertical support to form a flat structure (hereinafter referred to as a horizontal frame). 2 shows an embodiment of a preferred horizontal frame.

The horizontal frame is installed in as many layers as necessary and is connected to the main support and the vertical support to form a jacket.

The horizontal frame is configured as a head portion including a float blocking portion to be installed a vibration damper and a body portion for providing a space to accommodate the equipment to be protected.

A virtual line connecting the four main supports is arranged in a square to draw a closed polygon that sufficiently covers the horizontal area of the tidal current power plant for a space for the space.

In addition, the remaining two main supports (21A, 21A ') are vertically spaced apart by a predetermined distance to be described later on a straight line passing through the center of the body portion along the S-S' direction.

Here, S-S 'direction indicates the flow direction of the algae at high and low tide.

The main supports 21A, 21A ', 21B, 21B', 21C, and 21C 'disposed at predetermined intervals are fixed in such a manner as to penetrate the underground rock of seawater and fix the jacket. It is connected to a plurality of horizontal frames to be described below to form a jacket body.

The horizontal frame forming the layered structure of the jacket will be described with reference to FIG. 2.

Body portion 41 has four main supports (21B, 21B ', 21C, 21C') forms a vertex and is configured in a rectangular shape, each connected by a horizontal support (31).

The interior of the body portion 41 is also divided into a grid shape by connecting a plurality of horizontal supports 31 at right angles to each other to form a space for accommodating the tidal power generation equipment.

The head portion 40 has three main supports 21A, 21B, 21C and two vertical supports 22B, 22C forming vertices in the order of 21A, 22B, 21B, 21C, 22C, and each vertex is a horizontal support. Form a pentagonal shape connected by 31.

In addition, the main support 21A ', 21B', 21C 'and the vertical support 22B', 22C 'are similar to the opposite side of the body portion 41 to which the head 40 is connected 21A', 22C ', 21C'. , 21B 'and 22B' form vertices, and each vertex forms another pentagonal head portion 40 connected by a horizontal support 31.

On the other hand, each of the vertical support (22B, 22C and 22B ', 22C') may be replaced with the main support if necessary to improve the fixing force of the jacket.

The main frame 21A of the head portion 40 and the vertical supports 22B, 22C connect the main frame 21A 'and the vertical supports 22B', 22C 'of the head portion 40 opposite to the horizontal supports. Each horizontal support is a support for fixing the vibration damper, and when the horizontal support only refers to the vibration damper support (31A).

Strengthen the strength by installing another horizontal support 31 in parallel with the vibration suppressor support 31A at regular intervals from the vibration suppressor support 31A to the head.

When it is necessary to further reinforce the strength of the head portion 40 to protect the tidal power generation equipment, the reinforcing support 32A formed in the head chatter shape in the head portion 40, and the reinforcement support 32A in the form of the bucchat flesh ) Can be formed another reinforcing support (32B) formed at regular intervals.

In the present embodiment, preferably, four horizontal frames arranged as above are arranged at appropriate intervals, and six main supports 21A, 21A ', 21B, 21B', 21C, 21C 'and four The jacket is formed by fixing using the vertical supports 22B, 22B ', 22C and 22C'.

Of course, the number of horizontal frames installed in a layer is not limited to four, but can be added or subtracted as needed depending on the height of the equipment to be protected and the strength required for the protective equipment.

The jacket thus formed is installed such that the two head portions 40 of the horizontal frame correspond to the direction of the current, ie, S-S 'in the drawing.

Figure 3 is a schematic diagram for helping to understand the overall appearance of the jacket by the above configuration.

Main frame (21A, 21A ', 21B, 21B', 21C, 21C ') and vertical supports (22B, 22B', 22C, 22C ') and head part, excluding the internal horizontal supports of the horizontal frame and forming the overall appearance Only the horizontal support (31) constituting the skeleton of the 40 and the body portion 41 showed a schematic view of the jacket.

At this time, the rectangular portion formed by the main support 21A ', the vibration damper support 31A and the vertical support 22C' of the uppermost and lowermost horizontal frames is defined as the main blocking portion 50, and is perpendicular to the main support 21C '. The rectangular part formed by the support 22C 'and the two horizontal supports 31 of the uppermost and lowermost horizontal frames connecting the two pipes is defined as the side blocking portion 70.

In addition, two surfaces composed of the main blocking part 50 and the side blocking part 70 are defined as floating material blocking parts 42. Since the floating block 42 has a symmetrical structure of the jacket, a total of four will be present.

Meanwhile, in the present invention, the head portion 40 including the float blocking portion 42 is coupled to the body portion in order to divide the impact load caused by the float from the body portion 41.

 Therefore, when the impact load expected by the float is small or difficult to connect the head portion 40 with the body portion 41 due to the terrain, etc., the head portion 40 including the float blocking portion 42 is separated from the main. It may be provided with a support and separated from the body portion (41).

The detailed configuration of the float blocking portion 42, the main blocking portion 50 and the side blocking portion 70 will be described in detail below.

As shown in FIG. 8, the main blocking unit 50 includes a vibration damper 51 including the main screen 60 and an auxiliary screen 61. The main blocking unit 50 is fixed to the jacket body of the main blocking unit. The join plate 55 and the screen beam 54 are provided.

It demonstrates concretely below.

The vibration damper according to the present invention has the same basic configuration as the conventional rotary damper shown in [FIG. 1], but unlike a conventional vibration damper installed in a concrete structure in a channel of land, a rod-shaped (pipe type) supporter There is a difference in detail because it has to be installed in, and the flow of algae should be considered.

A vibration damper according to a preferred embodiment of the present invention will be described with reference to FIG. 5 and FIG. 6.

The vibration suppressor frame of the present invention is composed of three parts of the upper and lower, that is, the upper frame 52A, the middle frame 52B, the lower frame 52C, as shown in FIG. 5, and are coupled to each other using an anchor 53. It is formed into a single vibration damper frame.

The intermediate frame 52B and the lower frame 52C are provided with a vibration damper support groove 56 having one right side open to accommodate the vibration damper support of the jacket so as to accommodate the vibration damper support 31A for fixing the vibration damper to the jacket. do.

In addition, a screen beam groove 57 having one open right side is provided at predetermined intervals so that the screen beam 54 for fixing the main screen 60 is accommodated between the vibration damper support grooves 56.

6, the screen beam 54 is fixed by welding the fixing bracket 63 to the main support 21A 'and the vertical support 22C' of the main blocking unit 50, as shown in FIG. Place it over the bracket and tighten it with bolts.

At this time, the installation position of the screen beam 54 should be a position corresponding to the screen beam groove 57 formed in the intermediate frame and the lower frame (52B, 52C) of the vibration damper.

When the frame 52 of the vibration damper is installed at the main cutoff part of the jacket, as shown in FIG. 5, the vibration damper support groove 31 is accommodated in the vibration damper support groove 31A of the jacket and the screen is provided in the screen beam groove 57. Beam 54 is received.

Thereafter, the support fixture fixing bundle 58 matching the shape of the open part of the vibration damper support groove 56 is blocked by the bolt fastening method or welding to open the entrance of the vibration damper support groove 56 to fix the vibration damper support 31A. In the same manner, the screen beam fixing bundle 59 corresponding to the shape of the open portion of the screen beam groove 57 is blocked by the bolted fastening method or welding to block the open inlet of the screen beam groove 57 by the screen beam 54. Fix it.

Through the above process, the frame 52 of the vibration damper is fixed to the jacket.

The configuration of the main screen 60 will be described with reference to FIGS. 10 and 11.

The main screen 60 is formed by continuously welding the screen blades 62 to the plurality of auxiliary plates 75 and the auxiliary screen beams 74 at regular intervals.

As shown in FIG. 10, the auxiliary plate 75 and the auxiliary screen beam 74 have the same width so as to be fixed to the join plate 55 and the screen beam 54 with bolts and nuts, respectively. And a long plate shape formed with a length and a hole for bolting in the same position.

Screen blade 62 also has a long plate shape, such that when the blade is bonded to the auxiliary plate 75 and the auxiliary screen beam 74 as a whole, the blade is erected form.

However, in the present invention, when the screen blade 62 is vertically welded to the auxiliary plate 75 and the auxiliary screen beam 74 like the conventional vibration damper, the vibration damper is mounted on the vibration damper support 31A of FIG. 2. When the screen blade is inclined by the angle θ with respect to the flow of algae S-S 'direction, the algae flow is obstructed.

Therefore, in the present invention, as shown in FIG. 11, the individual screen blades 62 are welded at a predetermined angle so as to coincide with the flow S-S 'direction of the tidal current.

Fixing of the main screen 60 will be described with reference to FIGS. 6 and 7.

The main screen 60 is fixed by combining the screen beam 54 fixed to the jacket and the join plate 55 to be described later.

The joining plate 55 is formed of an elongated rectangular plate as shown in FIG. 7 so that the bolt fastening hole 73 for fixing the main screen 60 in a bolting manner is repeatedly formed through the iron plate. do.

In addition, one surface of the join plate 55 is welded to the join plate 55 at a right angle with a plurality of iron pieces 74 which are dug in an arc shape so as to be welded and attached to the vibration damper support 31A.

When the arc-shaped iron piece 74 of the joining plate 55 formed as described above is welded to the vibration damper support 31A, the front surface (see FIG. 6) becomes a flat plate and the auxiliary plate 75 of the main screen 60 is bolted. It is easy to fasten with.

The auxiliary plate 75 and the auxiliary screen beam 54 of the main screen 60 are fixed by combining the joining plate 55 and the screen beam 54 with the bolt fastening method shown in FIG. 6, respectively. 60) is installed in the main block 50.

The auxiliary screen will be described with reference to FIG. 8.

Since the main support 21A 'has the shape of a large cylinder, a space exists between the vibration damper 51 and the main support 21A'.

In order to block the space, the auxiliary screen 61 having the same screen blades arranged at regular intervals with the screen blade 62 of the main screen 60 is installed.

Side blocking portion 70 will be described with reference to FIG.

The side blocking part 70 according to the preferred embodiment of the present invention is divided into three parts by a horizontal support 31 connecting the main support 21C 'and the vertical support 22C'.

In order to block these three space parts, three side screens 71 having the same shape and size as the space parts and a fixing bracket 72 for fixing them to the jacket are provided.

The side screen 71 is formed by arranging screen blades at predetermined intervals in a steel frame formed in a rectangular shape. However, unlike the case of the main screen 60, it is not necessary to reinforce the strength in order to prepare for a direct collision of the float, so the screen blade may be formed in a thin rod-like structure.

Since the fixing bracket 72 has a horizontal support 31 and a vertical support 22C 'of the side blocking portion, a cylindrical pipe, a round groove is formed at the bottom so as to be fixed in close contact with the surface thereof, and the upper surface on which the side screen 71 is seated. The two surfaces are formed at right angles, and the bolt fastening hole 73 is formed on the surface of the side screen 71 in contact with the edge.

The fixing bracket 72, the horizontal support 31, and the vertical support 22C 'are joined by welding, and the fixing bracket 72 and the side screen 71 are fixed by bolts.

The float screen 51 including the side screen 71 and the main screen 60 and the auxiliary screen 61 are shown in FIG. 8.

This float blocking portion 42 preferably has four parts symmetrically and has the same configuration.

The motor base will be described with reference to FIG. 9.

In the head portion 40 of the uppermost horizontal frame, the auxiliary support between the main support (21B, 21B ', 21C, 21C') in contact with the body portion 41 and the auxiliary support 32 closest to the main support ( And base support 65 in parallel with 32).

On the auxiliary support 32 and the base support 65, there is provided a motor base 66 having a planar rectangular shape penetrating in a rectangular shape.

The motor base 66 is mounted with a motor (not shown) for driving a vibration suppressor.

Hereinafter will be described the operation according to a preferred embodiment of the present invention.

The tidal current power plant protection facility according to the present invention basically consists of a frame structure (frame formed by a rod-shaped or pipe-shaped member) and thus does not block the flow of water as much as possible. In addition, the screen blade 62 of the main screen 60 in accordance with the flow direction of the water has the same effect.

In addition, since the main blocking portion 50 of the jacket is formed to have a predetermined angle with respect to the direction of the bird, even if the floating floats and collides, the impact due to the collision is compared to the case where the main blocking portion 50 is installed at right angles to the direction of the bird. In addition to being reduced, most of the floats flow to both sides of the float shield 42.

For example, referring to FIG. 2, when the angle formed between the vibration damper support 31A and the axis of S-S 'is θ, theoretically, θ is 0 ° or more to form a slanted surface with respect to the direction of the current. It becomes less than °.

However, when θ approaches 90 °, the float blocking unit cannot properly float the float. If θ is too sharp, the width W of the body is fixed, so that the length H of the head is too long and the support is unnecessarily increased.

Therefore, θ is preferably formed in the range of 45 ° to satisfy both of these conditions. Further, the "predetermined distance" H where the main supports 21A and 21A 'mentioned in the introduction of the above embodiment are arranged is preferably L + W / 2.

In addition, the side screen 71 of the side blocking unit 70 is blocked by the main blocking unit 50 to block the floating flow to both sides of the main blocking unit 50 to the algae power generation facility by the vortex.

As described above, most of the floats flow to both sides of the floating block 42, and only a few of the floats are wound or caught on the screen, and these floats are formed in the same manner as the prior art shown in FIG. The rake of 51 is lifted to the top of the jacket (not shown).

However, the float lifted by the top plate of the jacket is very small compared to the general case where the vibration damper is installed in the channel of the land, so the conveyor method usually used for the treatment of the float is less efficient and after collecting the float on the top plate of the jacket It can be operated by collecting floats regularly.

In addition, the vibration damper according to the present invention does not need to consider the load of the suspended float because it lifts only the minimum float unlike the usual case, it can be installed perpendicular to the water surface.

Although the preferred embodiment has been described above, the technical idea of the present invention is not limited to the above-described preferred embodiment, and the protection facilities of various tidal power generation facilities within the scope not departing from the technical idea of the present invention specified in the claims. Can be implemented.

In addition, these protection facilities can be applied not only to tidal power generation facilities, but also to other facilities that need protection by being installed at sea.

As described above, the algae power generation facility protection facility according to the present invention does not prevent the algae necessary for algae generation because it has a frame structure.

In addition, by improving the frame of the vibration damper it is easy to install in the jacket of the tidal power plant protection facility.

In addition, the main blocking portion 50 installed to form a predetermined angle with respect to the direction of the bird reduces the impact caused by the float, the auxiliary screen 61, the main screen 60, the side screen 71 of the float blocking portion 42 ) Flows most of the float to both sides of the floating block 42 to protect the algae power plant.

Accordingly, the present invention reduces the impact that the vibration damper receives from various floats, increases the life of the vibration damper, and provides a protection facility that is easy to install by removing a discharge device installed in a conventional vibration damper.
