Abstract

In the known motor boat raceway, the wave elimination device connects the competitive water-side wave elimination body having a plurality of cross-sections with a connecting member and connects the wave beyond the surface plate of the course-side wave elimination body to a U-shaped wave elimination space. Waves are dropped in and wound around, and the water is eliminated. The water is guided into the water from the bottom of the wave clearing opening. The U-shaped wave elimination space provided is subjected to the resistance of the wave, and the wave elimination device oscillates not only in the large wave but also in the small wave, so that a sufficient wave elimination effect cannot be obtained.

Except for the horizontal plane extending from the trailing edge of the surface, the cross section of the course and the rock wall side having the same configuration are symmetrically connected to the hollow body having an umbrella shape, and the wave is roughly serrated. The stepped portion and the wave drop opening portion have a shock absorbing portion in a motorboat raceway that guides the cross-section of the course side into an umbrella-shaped hollow body, drops it underwater to eliminate the wave, and effectively eliminates the large wave and the small wave. It is a wave erasing device.

Description

A water-wave breaking trap having a shock absorber for use in a motorboat racing water}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wave clearing device having a shock absorbing portion in a motor boat raceway, and more particularly to a known wave clearing device provided on the water surface of a motorboat race track in which race boats hang at once. The present invention relates to a wave elimination device having a shock absorbing portion in a motorboat raceway capable of eliminating large waves and small waves.

At the motorboat race track, six raceboats compete ovally in Hangzhou for the desired number of times, with six boats ellipsing at a high speed of about 80 km / h. Therefore, in addition to the waves created by these boats in Hangzhou, waves generated by natural conditions such as wind collide with devices in rock walls and other motorboat race tracks, and are caused by the waves that protrude from them. The boat may overturn.

As described above, each boat is Hangzhou at a high speed of about 80 km / h, so each boat at the corner is slid sideways to collide with rock walls, poles, towers, and other equipment, or lose its center. Athletes who fall off may collide with a rock or these devices and be injured, and in the worst case, death.

(1) In the known motor boat raceway, as shown in the figure, the wave clearing body on the competitive water side having a triangular cross section and the rock wall side wave eliminating body having a triangular cross section are connected through a connecting metal member. In the U-shaped wave elimination space formed by the connection, the wave passing over the surface plate of the competitive water-side wave elimination body is dropped into the U-shaped wave elimination space to be swept away, and the wave is erased, and the bottom of the U-shaped wave elimination space is removed. The wave is guided into the water from the wave clearing opening provided in the section, and the wave not yet erased is guided to the rock wall by the wave passing over the surface plate of the rock wall body having the triangular cross section.

(2) Each of the blocks of the wave canceling device assembled by connecting the competitive water surface wave canceling body having a triangular cross section and the rock wall side cleaning body having a triangular cross section was made relatively short in the longitudinal direction.

(3) The shock absorbing portion provided in the competitive water-side wave eliminating body whose triangle is in cross section of the wave eliminating device is fixedly attached via a triangular buffer portion attaching member.

As mentioned above, in the known wave elimination device, the following various faults arise.

(1) As described above, in the known motor boat raceway (Japanese Patent Office No. 54-35809, Japanese Patent Application No. 61-39833, Toshima Hamamura, and the inventor's net shape), FIG. 13 As shown in FIG. 2, the surface of the competitive water-side wave eliminating body is formed in a U-shaped wave eliminating space formed by connecting a competitive water-side wave eliminating body having a triangular cross section and a rock wall-side wave eliminating body having a triangular cross section through a connecting member. Waves falling over the plate are dropped into the U-shaped wave elimination space to be swept away, and the wave is eliminated, and the wave is guided into the water from the wave elimination opening provided at the bottom of the U-shaped wave elimination space, and the wave is not erased. Waves passing over the surface plate of the rock wall-side wave eliminating body having a triangular cross section are directed to the rock wall side.

However, since the components are integrally connected through connecting pipes, connecting metal members, and the like, there is a structural weakness and the number of parts increases, resulting in a complicated manufacturing process. Assembly and attachment work on the water side were cumbersome and inefficient.

(2) In addition, in the known wave abatement apparatus in a motor boat raceway, a U-shaped wave abatement space is formed between the course side and the hollow body having a triangular cross section on the rock wall side, so that the wave resistance It was easy to receive, and it waved not only in the big wave but also in the small wave, and it was not able to obtain sufficient wave elimination effect.

(3) In addition, in the known motor boat raceway, as shown in Fig. 11, since the shock absorbing portion is provided so as to extend from the inclined surface of the hollow body having a triangular cross section on the course side, the surface of the competitive water surface is When the boat off the course collides with the buffer part, the stability of the boat is impaired because it is directed upward, and the effective buffering effect cannot be obtained.

(4) Moreover, since there are many connection parts of known wave elimination devices and the connection parts become weak, it is necessary to reinforce the part.

It is a wave elimination device which has a buffer part in the motor boat raceway which consists of an inverted T-shaped pin formed by the said vertical piece.

The second aspect of the present invention relates to a buffer portion that allows free adjustment of the height of the inverted T-shaped pin plate formed by the vertical piece protruding from the bottom surface of the course side and the rock wall side with the hollow body having an umbrella shape. Branches are wave suppressors.

The U-shaped wave eliminating space formed at the bottom of the wave eliminating device installed by symmetrically connecting the umbrella-shaped hollow body is abolished, and the substantially cross section of the course side by the substantially serrated wave eliminating step portion and the wave dropping opening portion. It guides into this umbrella-shaped hollow body, falls in water, and eliminates a wave. It is a wave scavenging device having a buffer section in a motor boat raceway that effectively cancels large and small waves.

(1) As described above, the wave clearing device 10 having the shock absorbing portion in the motorboat raceway of the present invention has the course side except for the horizontal surface 12c extending from the rear end of the wave drop surface 14. Since the hollow bodies A and B having an umbrella-shaped substantially cross-section on the side of the rock wall have the same constitution, mold making at the time of fabrication is facilitated, and accordingly, fabrication, transportation, and assembly are extremely easy.

(2) And as shown in FIG. 11, 12, the wave from the water surface of the course side of a motor boat raceway is the surface longitudinal direction of the said inclination plate 12 of the hollow body A whose substantially cross section of the said course side is an umbrella shape. Is partially erased by the resistance of the plurality of substantially serrated wave elimination steps 12a and 12a, and is led downward from the wave drop openings 12b and 12b to the bottom of the inclined plate 12, and the horizontal reinforcement. It is guided in the longitudinal direction from the plate 20, falls into the water and is erased, and also falls from the wave passing opening 14b to the bottom via the wave drop surface 14, and the surface of the inclined plate 12. Waves exceeding this level also fall through the wave drop surface 14 to the bottom and are erased.

(5) Since the U-shaped wave eliminating space provided in the state protruding from the bottom of the known wave eliminating device is abolished, the resistance of the wave received from the surface of the conventional course side is reduced.

(6) On the other hand, roughly the cross-sections of the course side and the rock wall side are formed by the vertical pieces 18 and 18 protruding from the bottom surface of the hollow bodies A and B according to the depth of the motor boat raceway. When it is necessary to adjust the height of the inverted T-shaped pin C, the bolt 18b of the inverted T-shaped pin C is taken out and replaced with an L-shaped steel plate 19a having a desired height to be screwed again. This makes it very easy to exchange, and height adjustment of the inverted T-shaped pin C is also facilitated.

(7) When the raceway slides sideways and collides with the shock absorbing portion F when turning the corner, unlike the known shock absorbing portion f, the shock absorbing portion F is always covered by the compression spring 28b. Since it is pressurized to the side, the shock applied to the raceboat by operating horizontally is absorbed, the raceboat is returned, and the stability thereof is not impaired.

(8) In addition, since the inverted T-shaped pin (C) functions as a center board or a weight balancer in a ship, in particular a boat, it is helpful to stabilize the wave removing device 10 installed in a floating state. will be.
