Description

  The present invention relates to a wave-dissipating device, and more particularly to a wave-dissipating device having a buffering function at a boat racetrack.

  At the racetrack, two turn marks (buoys) with six race boats moored at 300m intervals in the center of the race water surface are about 80km / h on average, and about 80km / h for straight running Draw an ellipse at the same time and race as many times as necessary.

  In addition to the pulling waves that these racing boats sail and make waves, waves generated by other vessels that run nearby, waves generated by natural conditions such as wind, waves on the racetrack quay, poles, towers, When the other boats collide with other equipment, make waves, and the return waves that bounce off interfere with the smooth sailing of each race boat, resulting in a fair race or causing each race boat to capsize There is also.

  Traditionally a race course. Even if the vehicle breaks off and collides with the wave-dissipating device, the raceboat and athlete (operator) can race safely without colliding with the quay, poles, towers, or other equipment by the guardrail with the shock absorber. I was able to do.

As a wave-dissipating device in a conventionally proposed racetrack,
JP-A-5-317530, JP-A-11-104364, JP-A-2001-120857, JP-A-2001-164537, JP-A-2001-170371, JP 2004-288334, JP 2005-342268 A and the like.

  (1) However, in recent years, the turn speed has increased due to the turn by the monkey turn (the boat rider steers from the seat of the race boat in the standing knee state) and the race boat engine output increase, so the player does not lose control. Also, the athlete's body is positioned higher than the top of the guard rail of the wave-dissipating device, so if he leaves the race course and crashes into the wave-dissipating device in this position, he will be thrown out of the raceboat's cockpit, There is a risk of jumping over and colliding with the steel material or pole of the wave-dissipating device.

  (2) In this way, the race boat collides with the guard rail of the wave-dissipating device, and the athlete thrown out from the race boat's cockpit collides with the steel material or pole of the wave-dissipating device and is injured. In some cases, fatal accidents may occur.

  (3) Therefore, assuming that the race boat collides, the metal part is covered with mat material etc. in order to prevent the breakage of the athlete who has fallen from the race boat to the return and guard rail of the wave breaker. However, the material cost of the cushioning material and the covering work of the cushioning material are considerable, but the effect is not sufficient.

  (4) In order to prevent this, it is conceivable to simply raise the guard rail of the wave-dissipating device, but the increase in the mass of the guard rail adversely affects the buoyancy balance of the entire wave-dissipating device and increases the entire projected area of the wave-dissipating device. Thus, the wave-dissipating device is easily affected by wind.

  (5) As shown in FIG. 10, the above-described wave-dissipating device is provided with the guard rail mounting plate 30 on the course side of the U-shaped wave-dissipating space 34, and the guard rail 32 is provided integrally therewith. In the case of a collision, the guardrail 32 is easily broken.

  (6) The length of one of the plurality of wave-dissipating devices installed in a vertical direction on the quay of the water surface of the current racetrack is 4 to 6m, and the width is 2m. Therefore, it cannot be made smaller than this.

  (7) Each wave-dissipating device is provided with two umbrella-shaped bodies facing each other, a U-shaped wave-dissipating space 34 is formed between them, and a wave return and guardrail 32 is reciprocated to the course-side umbrella-shaped body. It is provided so that it can freely move when the race boat collides.

  (8) However, in the case of a wave-dissipating device installed on the water surface of a seawater racetrack, oysters adhere to the bottom surface of the wave-dissipating device and proliferate easily, and the wave-dissipating device sinks into the sea and the wave-dissipating function is impaired. The wave extinguishing device must be landed and removed by human naval tactics within a limited period so as not to affect the race.

  (9) The removed oyster shells cannot be disposed of as industrial waste in some local governments, so they must be incinerated. Therefore, the amount of oyster shells to be incinerated is limited, raising separate problems. Since the race cannot be interrupted by the oyster shell removal work, the disposal process needs to be carried out quickly as described above.

  (10) And the repair or replacement work of the wave-replacing and guardrail or other parts of the wave-extinguishing device that is damaged by the collision of the race boat is carried out on fresh water or sea water. Yes, it cannot be handled urgently.

  The present invention solves the above-mentioned problems, and the first gist of the present invention is a glass fiber reinforced plastic cross-section acute triangle body having a required length, width and height, and an inclined side of the cross-section acute triangle body. A U-shaped recess formed in the middle in the longitudinal direction, a step formed at the upper end, a first U-shaped steel coupling fitting for connection provided in the U-shaped recess, and a first provided in the step A U-shaped steel connecting bracket for two connections, a metal quadrangular assembly bracket integrally provided on the lower surface of the first U-shaped steel connecting bracket for connection and the second U-shaped steel connecting bracket for connection; A guard rail mounting plate having a lower end pivotally attached to a support piece protruding from the rear of both end frames of the square assembly bracket made of metal, a guard rail provided in front of the guard rail mounting plate, and near the lower ends of both ends of the guard rail mounting plate It penetrates through the formed through hole, and the inner end is the second connection A guide bolt connected to a U-shaped steel fitting and having an outer end pivotally attached to a lower end of the guard rail; a compression spring wound around the guide bolt and constantly biasing the guard rail in the course direction; It is a wave-dissipating device having a buffering function in a boat race track that includes a buoyancy adjusting unit provided on the bottom surface of a metal quadrangular assembly fitting.

  According to a second aspect of the present invention, the metal quadrangular assembly fitting has a frame corresponding to a length and a width corresponding to the longitudinal direction of the acute-angled triangular main body, and is reinforced at regular intervals in the longitudinal direction of the frame. A frame is provided, an inverted L-shaped protrusion having a required height is formed at the rear end, and the bottom surface of the U-shaped recess of the acute-angled triangular main body together with the first connection U-shaped steel coupling metal A wave-dissipating device having a shock absorbing function in a boat racetrack, which is fixed to the stepped portion and fixed to the both end frames together with the second connecting U-shaped steel fitting.

A boat racetrack in which a horizontal partition plate is provided at a required location in the body, a buoyant body is provided at the top, a water tank is provided at the bottom, and a water supply pipe and a drain pipe are provided from the substantially rectangular frame toward the water tank. It is a wave-dissipating device having a buffering function.

  (1) A wave-dissipating device having a buffering function according to the present invention is provided with a guard rail mounting plate provided on the course side of the umbrella-shaped wave-repelling and wave-dissipating body on the opposite side of the course side, and its lower end pivotally attached to the assembly metal fitting. Therefore, when a race boat off the course collides with the guard rail, the guard rail mounting plate pivotally mounted with the lower end of the guard rail mounting plate as a pivot point partially rotates to the opposite side of the course side, Receiving race boats and protecting athletes.

  (2) Since the connecting U-shaped steel provided at the U-shaped recess and the step formed at the upper end does not protrude from the surface of the acute-angled triangle body, the racer loses the center of gravity. Injury can be prevented even if it jumps out of the cockpit and is thrown into the wave-dissipating device.

  (3) Accordingly, since the member protruding from the wave-absorbing device is eliminated, there is no need to cover with a cushion material as in the prior art.

  (4) Since water does not protrude at all from the surface of the acute angle triangular main body in this way, water is supplied to the water tank in the lower part of the buoyancy adjustment part provided at the lower part of the metal square assembly fitting through the water supply pipe and the drain pipe. By draining, it becomes easy to adjust the buoyancy of the wave-absorbing device having a buffer function.

  (5) In addition, the wave-dissipating device having a buffering function according to the present invention has a simple structure, so the number of parts is reduced, and production, transportation to the required racetrack, and installation work are facilitated. Compared with the apparatus, it can be remarkably shortened.

  (6) Furthermore, since the bottom of the wave-dissipating device is a flat surface, oysters are difficult to adhere and can be easily removed even if they adhere.

  (7) Further, the wave-dissipating device having a buffering function according to the present invention has an extremely small number of parts as compared with a known wave-dissipating device, so that it can be easily manufactured and assembled.

  (8) Finally, advertisements and advertisements drawn on the side of the course of the guardrail mounting plate can be easily seen from the audience seats on the stand.
