Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of competitive sports arena construction, in particular to a method for implementing a dragon boat competitive arena. BACKGROUND

[0002] The annual dragon boat race around the Dragon Boat Festival is a traditional cultural festival activity in China, and has now become a popular event in many countries. Due to its broad appeal and strong competitiveness, it is loved by people all over the world, and the International Olympic Committee is considering including it in the Olympic Games. At present, there are many dragon boat competitive arenas in China and around the world, but the existing dragon boat competitive arenas only demarcate an area in the water, simply determine the starting and ending points, and arrange multiple dragon boats horizontally at the starting point. After the starting signal is given, the dragon boats move forward vertically, and the first one to reach the designated ending point wins. However, during the race, there is no barrier between the fast-moving dragon boats on the water surface, resulting in frequent collisions between the dragon boats or between the dragon boats and stationary objects, causing serious safety accidents such as injuries and deaths of athletes due to severe impact, and the dragon boats are also severely damaged or even scrapped. The fairness of the starting point and ending point of the competition is also questioned. The above problems seriously affect the normal development of dragon boat competitive events, and the safety, fairness, and standardization issues have not been properly solved, so a method for implementing a dragon boat competitive arena is needed. SUMMARY

[0003] In order to solve the serious safety hazards and lack of fairness in the existing dragon boat competitive sports arenas, the present application aims to provide a method for implementing a dragon boat competitive arena.

[0029] II. Select an open water surface of a river or lake with a length, width and depth of about 600m, 30m and 1.2m or more, and there is no reef under the water surface of 1.2m or less in this range, and the water flow is not fast or even basically static, and the river or lake does not occupy the channel as the construction site of dragon boat competition; select the starting position at a distance of about 15m away from the shore in the open river, and determine the support stand pole 1 on the same horizontal line of the first row, and take the horizontal line as the starting point of the dragon boat competition of each race track 5; the proposed race track 5 between the horizontal support stand poles 1 should be wide enough to accommodate a competitive dragon boat longitudinally, and the distance between each race track 5 should be kept uniform.

[0030] III. The race track 5 is set in a straight line or a curved shape; that is, the support stand poles 1 on the first row of horizontal lines are aligned and vertically arranged at a certain longitudinal distance away from the first horizontal line, so that the longitudinal support stand poles 1 form a straight line and are parallel to each other, forming a straight line race track 5; or in order to increase the difficulty and ornamental value of the dragon boat competition, the position of the longitudinal support stand poles 1 is adjusted in parallel after 20m from the starting point of all race tracks 5, and is set in the required zigzag shape or arc shape, so that at least one part of each race track 5 has a curved shape of a straight line or an arc line; in this way, a straight line race track 5 or a curved race track 5 is basically formed, and each dragon boat arranged horizontally can occupy a race track 5 for longitudinal competition, that is, a plurality of race tracks 5 are arranged horizontally, which can accommodate a plurality of dragon boats for longitudinal competition at the same time.

[0031] IV. If the length of the race course of the race track 5 is set to be 100m, 200m, 300m or 500m or more, the length of the straight line formed by the longitudinally arranged support poles 1 should be extended by 10m or more to provide a buffer deceleration zone for the dragon boats after they cross the finish line, so as to avoid collisions between the dragon boats after they cross the finish line. The length of the race course and the width of the race track 5 can be determined according to the area of the river and the requirements. The length of the race course and the width of the race track 5 should be uniform. If the race track 5 is curved, the number, length and angle of the broken lines or the number, length and radian of the arcs of each race track 5 should be uniform to ensure fairness.

[0032] V. All the support poles 1 should be rust-resistant steel pipes or concrete poles with sufficient strength. They should be hammered into or planted into the riverbed soil layer to a sufficient depth. If a support pole 1 encounters a stone or hard object when it is hammered into the riverbed, a concrete pouring or an inclined support pole should be provided around the bottom of the support pole 1. The depth of hammering or planting into the riverbed, the concrete pouring or the inclined support pole should be able to ensure that the part of each support pole 1 exposed to the water can withstand an impact force of at least 300kg without displacement or tilting. All the support poles 1 should be set to have sufficient height above the water surface. They can all be set to have the same height above the water surface for aesthetic purposes.

If multiple isolation barrier belts 3 are provided, multiple isolation barrier belts 3 can be parallelly arranged on the sleeve 2-1 with a spacing of not more than 30cm from the water surface. Each isolation barrier belt 3 should be able to withstand a tensile or impact force of at least 300kg. The isolation barrier belts 3 on both sides of the race track 5 work automatically with the water level due to the buoyancy of the buoyancy device 2 and the isolation barrier belts 3 sleeved into the buoyancy tube in contact with the water surface. The isolation barrier belts 3 can effectively prevent adjacent competing dragon boats from colliding and assist in the self-rescue of fallen athletes. If the water level of a river or lake changes very little throughout the year, the isolation barrier belts 3 can be longitudinally welded or fastened on the longitudinally arranged support poles 1 without the need for a separate buoyancy device 2. In order to be more secure, two rows of isolation barrier belts 3 can be parallelly arranged with a distance of 0.3-1m between adjacent race tracks 5, so as to form an isolation zone 6 with a certain distance between the two adjacent race tracks 5. In this way, a race track 5 is formed by multiple race tracks 5 arranged transversely, which can simultaneously accommodate multiple dragon boats for longitudinal safe and fair competition.

[0034] Seven, in order to ensure that the dragon boat race in the same starting point position, on the first row of the support pole 1 outside the lateral line set entry blocking mechanism 4, entry blocking mechanism 4 by the entry of the metal rail 4-3 above the fixed connection of steel wire rope 4-2 and through the pulley 4-1 and play winding, loose effect of the winch or winding motor 4-4 connection installation; each race 5 can be set entry metal rail 4-3, or all race 5 set into a whole entry metal rail 4-3, by electric automatic control or manual control at the same time downward opening or upward winding close all race 5; set entry blocking mechanism 4 should be adjusted to the installation position distance or the length of steel wire rope 4-2, in order to ensure that the entry of the metal rail 4-3 is placed in the distance between 2-50 cm above the water surface, preferably, in the absence of the order of the competition, the entry of the metal rail 4-3 can effectively prevent each participating dragon boat into the race 5 race, force each dragon boat almost all stop in the same starting line, but also can ensure that the competition order when the steel wire rope is quickly released, so that the entry of the metal rail 4-3 can quickly sink into the river bottom, each race 5 entry can also be opened at the same time quickly start fair competition.

[0035] Eight, the end of each race 5 race course is set a whole end of the ribbon to warn; each support pole 1, buoyancy device 2, isolation blocking belt 3 can be set warning signs, flags or advertising.
