Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wave-dissipating device, and in particular to a wave-dissipating device with guard rails and its connecting mooring and fixing device for use in boat racecourses.
Regarding improvements to No. 139579 (Special Publication No. 54-35809).

At a boat racecourse, there are undertow waves created by race boats and rescue boats sailing together, undertow waves created by ships passing outside the racing water surface, waves caused by natural conditions such as wind, and these waves. The boat may collide with the quay or other equipment in the racecourse, and the returning waves may impede the sailing of each raceboat and cause a tipping point.

Furthermore, each boat sails at high speeds (up to 80 km/h), so when turning around a corner, the boat skids and ends up on the quay.
Athletes who collide with poles, towers, or other equipment, lose stability, and are thrown from the boat may collide with the quay or these equipment, resulting in injury or, in the worst case, death.

The main purpose of the present invention is to
It is installed in a stable state while floating on the water surface in front of the tower and other equipment, and dissipates the above-mentioned undertow and return waves, eliminates actual damage caused by wave creation, and ensures smooth high-speed navigation for each boat. wave equipment.

A second object of the present invention is to provide a guard rail that protects the boat and the athletes by its cushioning effect even if the boat or the athlete collides with the quay or the above-mentioned equipment, and provides a safety measure for the athletes. provide.

The third object of the present invention is to easily connect the molded bodies manufactured separately for convenience of transportation, etc., and connect them with a flexible structure in a desired straight or curved shape to match the racing water surface of the boat racecourse. We provide a wave dissipating device that can

Embodiments of each invention will be described with reference to the drawings. Fourth
In Figures 6 to 6, the central part in the longitudinal direction is a U-shaped space 2, and sloped sides 5 and 6 ascend from the front and rear edges 3 and 4 toward the U-shaped space, and the relationship between the U-shaped space and the sloped sides is The connection part is a right angle stepped part 7, 7, and both side edges 8, 8
A plurality of drainage notches 9 are formed at regular intervals in the longitudinal direction at the bottom of the U-shaped space.
A glass fiber-reinforced plastic molded body 1 is manufactured in which the lower sides of the inclined sides 5 and 6 on both sides of the U-shaped space are open. Both inclined sides 5, 6 of the molded body
A buoyancy body 10 made of hard polyurethane or the like as shown in FIG. 7 is fixed to the back side of the wave dissipating device A.

The guard rail mounting bracket shown in FIGS. 9 and 10 is a metal square pipe frame 20 having the length of the plastic molded body 1 described above and a width that fits into the right angle steps 7 and 7 on both sides. Metal brackets 21 are fixed and reinforced at regular intervals to the metal brackets, and arms 22 are attached to the front edge 3, that is, the arms 22 are inclined toward the course.
This is reinforced from the rear side to the front with supports 23, and guard rails 24 made of glass fiber reinforced plastic are fixed to these arms 22 to form a guard rail device B.

In Figures 9 to 13, guard rail mounting bracket 20
A horizontal through hole 20' is provided near each end of both sides of the
are drilled, and a metal ring 25 is inserted around the through hole.
, and one of the cylindrical rubber 26 having a central through hole 26' as shown in FIGS. 11 and 12 in these rings 25.
The ends are tightly fitted, and the other ends are fitted into the adjacent through holes 2.
0', ring 25, hole 26' of rubber 26, ring 2
5. Pass a bolt through the through hole 20', fit and tighten nuts (both not shown) on both ends of the bolt,
A device C is provided which fits into the metal ring 25 of the molded body 1 to connect the two.

As shown in Figure 1, a molded body of many blocks 1, 1
are floated at a predetermined point on the water surface of the racecourse, arranged in series, each end of each molded body is brought closer to each other in sequence, and the connecting cylindrical rubber 2 is placed inside each metal ring 25 as described above.
6 are tightly fitted and connected to form a wave dissipating device A. Therefore, by fitting cylindrical rubber 26 of different lengths as desired, the plurality of molded bodies 1, 1 can be installed not only in a straight line but also in a curved or other desired shape depending on the racing water surface of the boat race course.

As described above, the molded bodies 1, 1 are connected to a predetermined length to form one wave dissipating device A, which is installed in a floating state on the water surface in front of rock walls, poles, towers, and other equipment at a boat race course. Also, if necessary, moor it in a straight line and fix it to the rock wall. Since the molded bodies 1, 1 are chevron-shaped, they are installed in a stable state.

The undertow created by the sailing of each boat passes over the uphill slope side 5 of the wave dissipating device A and passes through the U-shaped central space 2.
The waves fall into the water, are guided downward through the drainage cut 9 at the bottom, and are dissipated underwater. The waves that are not dissipated in the central space 2 go beyond the space 2, are guided from the downward slope side 6 of the device to the water surface on the opposite side, and collide with the rock wall or other equipment behind, where they bounce back and are weakened. The wave returns from the inclined side 6 to the central space 2 as a return wave.
The waves fall into the water, are guided into the water through the notch 9, and are completely dissipated.

Furthermore, according to the present invention, even if a boat traveling at high speed deviates from the course and collides with the guard rail device B via the uphill slope 5, the shock absorbing effect prevents the collision and protects the athletes and the boat from an accident. .
