Project Overview:
The kayaking still water race is a race in a calm water course where the athlete passes through a clearly marked and unobstructed course in the shortest possible time. The distance between the Olympic Games is 500 meters and 1000 meters.
The kayaks originated from a pelt boat made by Eskimos in North America on a wooden stand with animal skins. In 1865, Scotland's John MacGregor made a 4 meter long, 75 centimeters wide and 30 kilograms "Noble Noyes" kayak on a faux-pelt boat and drove across Sweden, Finland and Germany. ,United Kingdom. It was widely carried out in Europe in the 1890s.
Venue facilities:
In the Olympic Games, the kayaking hydrostatic competition usually uses a water track together with the rowing competition. In order to meet the needs of the rowing competition, the track must meet the requirements of the following minimum measurement range:
1, 1400 meters long (straight line distance), 120 meters wide, 2 meters minimum depth; the side of the river with at least one straight side of the fairway is 50 meters away from the first fairway.
2. The river bank is a gentle wave-breaking slope, which is built up of large stones or other special materials so that the waves do not roll over the embankments. A dedicated channel is set up on the surface of the water to allow contestants to enter the competition area or training area. Canoeing in the still water Olympic Games is between 1000 meters and 500 meters. The competition uses 9 fairways, each of which is 9 meters wide; in the layout of the competition fairway, it must be arranged according to the “A1-bano†system specified by the rules. In the Olympic Games, automatic starters and electronic timing systems must be used.
3. One of the important facilities on the venue is the terminal tower. This is the core area of ​​the game. It is usually a small building of 4 or 5 floors. It is used as the terminal timing system operation room, the terminal timing room, the arbitration room, the competition committee, the end point video room, the broadcasting room, and the media camera room. Under normal circumstances, the VIP area is adjacent to the terminal tower to facilitate the athletes to watch the wonderful performance through the finish line.
4. Another important facility is the boathouse. The boathouse is generally close to the upper and lower water piers and is close to the athletes' activity area and other competition facilities. The racing boat is usually stored on a shelf. There are two kinds of open and closed boats. It is also possible to park the boat outside during the competition.
Project equipment:
Canoeing water
Most modern kayaks and rowing boats are made of wooden frames. They are made of aeronautical plywood or glass steel. The shape of the kayaks is streamlined. The surface is smooth, light and narrow, and narrow and long like a shuttle. In addition to the open cockpit of the athlete on board, all decks are completely closed.
Hydrostatic kayak
The main accessories are pedals, seats, rudder, rudder, rudder and so on. International rules limit the length, narrowness, and minimum weight of kayaks.
The athlete sits in the cabin while paddling, facing forward, holding two paddles with two paddles in both hands to draw water on both sides of the ship, and use the foot to toggle the rudder bar to control the course. Paddle frequency up to 130 ~ 150 paddles / min, speed up to 5 meters / second or more.
The kayak rudder is an attachment on the kayak. It is a simple device that controls the direction of kayaks, including rudder blades, steering wheels, rudder ropes, and rudder rods. The rudder bar is on the athlete's pedal board. When the athlete paddles his feet to the pedal plate and needs to turn the kayak, the foot bar is toggled with the foot, and the rudder bar rotates around a fixed axis. When the T-shaped rudder rod rotates, the rudder rope is pulled and the steering wheel connected to the other end of the rudder rope is driven. The steering wheel is tightly connected to the rudder. In fact, the rudder rope moves the rudder blade and turns the kayak.
The rules of the game stipulate that if the kayak lengthens the length of the hull due to the rudder, the thickness of the rudder blade must be limited. The thickness of the rudder blades for single and double boats must not exceed 10 mm, and the thickness of the boat for four-person boats must not exceed 12 mm.
The kayak paddle is a tool for athletes to move kayaks forward. A kayak paddle is a two-blade paddle with paddles on both sides of the paddle. Its main structural feature is the perpendicular or near-vertical intersection of the two paddles. Depending on the direction of the blade deflection, the left and right paddles can be divided into left and right paddles. As the rules do not have strict and uniform regulations on the size and shape of paddles, the development of kayak oars has changed extremely rapidly in recent decades.
The weight, length, shape, paddle, and paddle size of various paddles can be selected based on the athlete's height, technical style, strength, gender, and boat type.
Still boat
Canoeists are in a single leg on the boat, the other leg is in a square foot, and a single blade paddle is held on both hands. There are left and right paddles. For example, the left paddler's right hand holds the "D" shaped handle. The left hand holds the paddle near the paddle, the right leg moves forward and the left knee rests on the pad.
Rowing boats do not have rudders. Athletes rely on paddles to maintain balance and control direction. Since each paddle has to be lifted after the paddle, and then it is inserted into the paddle, the speed of the boat is not as good as that of the kayak. The paddle frequency can reach 70 to 80 paddles per minute.
The raw material used to make the hull is aeronautical plywood or fiberglass. There is a limit to the length and minimum weight of a rowing boat.
The rules stipulate that the rowing boat must be manufactured symmetrically on both sides of the longitudinal axis of the hull, and there must be no rudder and any means capable of navigation.
The rowing boat can be fully open. If there is a covered deck, the enclosed part of the single rowing boat cannot exceed 150 cm from the bow and 75 cm from the stern. The open part of the double rowing boat is not less than 295 cm. The open part of the four-person rowing boat is not less than 410 cm. Single rowing boats and double boats can be fully open with a minimum length of 280 cm; the edge of the ship (the upper edge of the ship's rail) can extend along the entire defined opening, extending up to 5 cm on the ship.
A boat can have up to three reinforcement bars, each with a maximum width of 7 cm. During the competition, various electronic or electric instruments should not be placed on board, including pumps, speedometers, fatigue gauges, and heart rate monitors. Rowing paddles are tools for athletes to row a rowing boat. A rowing paddle is a bladed paddle paddle. There is a slight difference in the specifications for single rowing boats, double rowing boats, and quadruple rowing oars.
Rowing paddles are generally made of wood or fiberglass, and in recent years have been developed using carbon fiber as a material. The carbon fiber structure makes the paddle more robust, durable, light and easy to maintain. The cross-section of the paddle is usually circular, so that the paddle has a better directionality, is conducive to force, but also makes the paddle has a greater resistance to bending.
The blades of a rowing paddle are different from kayaks, and the blades are symmetrical along the centerline. Asymmetrical blades can create an unbalanced surface that produces torsional moments under dynamic forces. The blade of the rowing paddle plays a variety of functions for advancing, steering, and controlling the smoothness of the vessel.
