Description

The present invention relates to a windbreaker, and more particularly to a technique for reducing the influence of wind in a boat racetrack.

Conventionally, measures against wind in a boat racetrack have generally been carried out using a wind-dissipating plate attached to a wave-dissipating device. By using an uneven wind plate, it is possible to change the flow of wind upward and prevent the water surface from rippling. However, it was necessary to take measures such as evacuating or folding the eccentric wind plate in strong winds.
Therefore, there has been a demand for a structure that does not damage the venue against strong winds while reducing the influence of the wind on the venue.

Various techniques have been proposed for such problems. For example, in order to prevent the generation of waves due to the wind on the water surface of the boat racetrack, a wave-dissipating device provided with a wind-dissipating plate has been proposed (see Patent Document 1). More specifically, the structure is such that a plurality of eccentric plates are fixed to a plurality of columns for mounting the eccentric plates, and the eccentric plates are accommodated in a strong wind.
However, in the case of a sudden strong wind such as a gust, the problem cannot be solved because the accommodation cannot be completed in time and the eccentric plate is loaded, which may cause damage or collapse.

The windbreaker 1 according to the present invention floats on the water surface around the boat racetrack and is for reducing the influence of the wind from the surroundings on the inside of the boat racetrack, and is mainly a float 10, a connecting portion 20, and a windbreaker. It is composed of 30, a pillar 40, and a resistance plate 50.

The float 10 is for floating the windbreaker 1 on the water. The shape seen from above is a so-called boat shape such as an ellipse or an oval (FIGS. 1 and 2). By rounding the tip part, resistance from strong waves and water currents can be softened, and a wave-dissipating effect can be expected. Since it has such a shape, it can pass the flow of water.
A buoyant body 11 is built in and above the float 10. When the float 10 is floated on the water, the water surface is near the middle of the buoyancy body 11, and the float 10 can be floated by the buoyancy of the portion of the buoyancy body 11 below the water surface.
There is a skirt portion 12 at the bottom of the float 10, and a space through which water can flow is provided between the float 10 and the buoyant body 11, and the stability is maintained by the water flowing into this space (FIG. 4). The effect of the skirt portion 12 will be described separately.

A pillar 40 is erected substantially vertically near the center of the upper surface of the float 10. Further, a portion for fixing the end portion of the reinforcing portion 41 as a support for reinforcing the pillar 40 is provided at a predetermined position on the upper surface of the float 10.
A floor portion 13 is provided on a part of the upper surface of the float 10 (FIGS. 1 and 2). The floor portion 13 is installed between the connecting portions 20 so as to straddle the plurality of floats 10. By providing the floor portion 13, it is possible to smoothly move back and forth between the plurality of floats 10, so that work such as replacement of the windbreak plate 30 can be easily performed.

By arranging a plurality of floats 10 and connecting them with the connecting portion 20, the base portion of the windbreak device 1 is completed. In the past, an integrated one was used along the surface of the windbreak plate 30, but by arranging a plurality of floats 10 side by side, it does not go against the water flow at the place where the floats are placed on the water, and the strength is improved and stable. Improved sex can be obtained (Fig. 2). Further, since there is no water flow staying in the apparatus due to this shape, dust and the like are accumulated, and the generation of odor and the dust recovery process are improved.
A self-consumable ship bottom paint can be applied to the periphery and bottom of the float 10 to prevent the adhesion of aquatic organisms for about 5 years.

The connecting portion 20 is a rod-shaped fixing tool for fixing a plurality of floats 10. The float 10 is fixed by the plurality of connecting portions 20. Strength is required to stably fix the plurality of floats 10. Steel angle steel is used as the material. Further, in order to reduce the weight of the connecting portion 20 and facilitate maintenance, an FRP material may be used as a material, or a SUS specification or an AL specification may be adopted.

The windbreak plate 30 is a resistance to the wind. It is a plate of about 2m x 1m and is installed between the pillars 40. The windbreak plate 30 can be stacked in several stages in the vertical direction, and the windbreak plate 30 can be stacked in the height direction according to the desired windbreak region. Further, since one windbreak plate 30 is relatively small, it can be easily replaced. (Figs. 1 and 2).

The windbreak plate 30 is provided with a large number of through holes 31 so that the windbreak effect and strength can be balanced against strong winds. The windbreak plate 30 is bent at a predetermined angle with the protrusion 32 as an axis. By making the plate surface angled with respect to the wind, the wind direction can be swirled and the wind force can be attenuated.
The material of the windbreak plate 30 is reinforced plastic. With this material, seawater corrosion can be prevented and weight reduction can be achieved.

The resistance plate 50 is arranged between the floats 10 arranged side by side (FIG. 2). It has a protruding portion 51 whose center protrudes downward, and is fixed to the connecting portion 20 with bolts 60. The vicinity of the protrusion 51 is below the water surface. The resistance plate 50 prevents the wind from escaping between the floats 10. It also has a wave-dissipating effect. Details will be described separately.

The effect of the through hole 31 of the windbreak plate 30 will be described with reference to FIG. As shown in FIG. 3A, through holes 31 are provided substantially evenly on the surface of the windbreak plate 30. The number and size of the through holes 31 can be adjusted depending on the degree of strong wind at the place where the holes are installed.

FIG. 3B is a schematic view when a wind hits the windbreak plate 30, and is a view of the windbreak plate 30 as viewed from above. The wind hits the windbreak plate 30 from the left. One part is stopped by the windbreak plate 30, and the other part passes through the windbreak plate 30. The force of the wind is significantly reduced by the windbreak plate 30. Further, the load on the windbreak plate 30 due to the wind is reduced as compared with the case where there is no through hole 31 because a part of the wind passes through. Therefore, it is possible to avoid damage and collapse due to strong winds while maintaining the windproof effect.

FIG. 3C is a schematic view showing the movement of the wind when the windbreak plate 30 further has a protrusion 32. A part of the wind passes through and the other part of the wind hits the windbreak plate 30. When it hits the windbreak plate 30, since the windbreak plate 30 has an angle, the direction of the wind changes, and the load on the windbreak plate 30 is reduced. Therefore, the load during strong winds can be further reduced.

The effect of the protrusion 32 of the windbreak plate 30 will be described with reference to FIG. FIG. 5 is a schematic view when a wind hits the windbreak plate 30, and is a view of the windbreak plate 30 as viewed from above. The wind hits the windbreak plate 30 from the left. The windbreak plate 30 has a protrusion 32, and the protrusion 32 has a structure that bends near the center when viewed from both fixed ends. The directions of the protrusions are adjacent windbreak plates 30 and face each other in opposite directions. With such a structure, the same effect can be generated regardless of which surface of the windbreak plate 30 the wind hits. When the wind hits the windbreak plate 30, the surface of the windbreak plate 30 has an angle with respect to the wind, so that the direction of the wind changes, a swirl state is formed, and the wind force can be attenuated. By providing the protrusion 32 on the windbreak plate 30 in this way, it is possible to avoid damage and collapse due to strong wind while maintaining the effect of windbreak.

The windproof and wave-dissipating effects of the resistance plate 50 will be described with reference to FIG. FIG. 6 is a schematic view when a wind hits the resistance plate 50, and is a view of the resistance plate 50 as viewed from the side surface. The wind hits the resistance plate 50 from the left direction. The resistance plate 50 has a protruding portion 51 whose central portion protrudes downward. The resistance plate 50 has a structure that is fixed at the longitudinal end of the float 10 and bends downward at the central portion in the longitudinal direction. The protrusion 51 of the resistance plate 50 is below the water surface.

The wind A above the float 10 is prevented by the windbreak plate 30. The wind B in the gap on the side surface of the float 10 hits the resistance plate 50. Since the protruding portion 51 of the resistance plate 50 is below the water surface, the wind can be prevented without slipping through. Further, the wave C can reduce the momentum by hitting the projecting portion 51, and the wave-dissipating effect can be obtained.
In this way, the resistance plate 50 can obtain a windbreak effect and a wave-dissipating effect.

The wave-dissipating effect of the skirt portion 12 will be described with reference to FIG. As shown in FIG. 4A, the lower space of the float 10 is filled with water.
FIG. 4B is a diagram assuming that the bottom of the float 10 is sealed. Since it is sealed, water does not enter. In this case, the water flow flows from left to right without stagnation, and the movement of water cannot be reduced.
On the other hand, in FIG. 4C, the presence of the skirt portion 12 causes the water flow to swell in the space near the bottom of the float 10 and reduce the movement of the water.
As described above, the skirt portion 12 on the outer periphery of the float 10 acts as a resistance portion of water, and has an effect of preventing and reducing the shaking of water.

The windbreaker 1 according to the present invention having the above configuration is used by floating on water, and at that time, a quay or a mooring pile is used so as not to move freely on the water due to the force of water flow or wind. It will be moored at the required location on the water by mooring it with a wire or chain, or by using an anchor.

According to the windbreak device 1 according to the present invention having the above configuration, the influence of strong wind can be reduced, so that damage to the device due to strong wind can be avoided without any special measures, and the race environment of the boat race track can be improved and the environment can be improved. It is possible to reduce maintenance work.

Moreover, since all the constituent parts can be considered as maintainable parts, maintenance can be facilitated.
Further, since the number of moving parts is small and the structure is simple as compared with the conventional product, the number of parts can be significantly reduced and labor can be saved.

Furthermore, since the structure is simple and the number of parts is small, it is easy to assemble, so it is possible to shorten the construction period of on-site construction, etc., and also realize efficiency of production and construction, cost reduction and sales price. Can be competitive.

In addition, by using FRP as the material, it is possible to reduce the weight of industrial waste disposal when responding to future replacements, improve durability, and extend the service life from the current 8 years to 15 years. can do.

The windbreak device according to the present invention can be used not only as a boat racetrack but also as general windbreak equipment, and has great industrial applicability as a technique for improving functionality and maintainability of windbreak equipment. I think.
