Description

Underwater roller-skating hockey

Technical Field

The invention relates to a water sports project with resistance reducing function, which is a roller skating and underwater hockey, belonging to the sports of the entertainment product field of 'human life requirement', the invention of the method is a technical scheme.

Background

The underwater roller-skating hockey is an innovative overwater playing method which is recombined on the basis of underwater hockey games and on the premise of referring to swimming, roller skating, water polo and other game items.

The method is characterized in that: breath on water, match under water, be applicable to the sports of masses and amusement sports.

Firstly, the water depth standard and characteristics of the swimming pool (figure 1)

Typically, a standard 50 m swimming pool is used for water polo games, the water depth is more than 2 m, and the water polo game feet cannot touch the bottom of the pool, which means that the players always swim or step on the water during the game.

Second, the significance and deficiency of underwater hockey game (fig. 2)

Sports cold knowledge-water hockey-

Underwater hockey is an emerging underwater ball game that resembles hockey and ice hockey. In this sport, the athlete wears swimming trunks, swim caps, masks, breathing tubes and gloves, wears rubber flippers, holds a short wooden club capable of swinging horizontally in water, and makes the whole team be black or white.

Underwater hockey games are typically played at the bottom of a swimming pool 25 meters long by 12 meters wide and 2-4 meters deep. The game ball is an oblate shaped lead cake. A wooden goal with the length of 3 meters, the width of 300 millimeters and the height of 180 millimeters is respectively arranged in the middle of the end lines of the two ends of the pool bottom with the width of 12 meters. Two teams participating in the game each have 6 persons, 3 foreheads, 3 backguards and no goalkeeper. The game stop command expresses the instruction of the referee by three methods of a bell-beating gesture and a language. The ball of the underwater hockey game is a relatively small shot sinking to the bottom of the pool, and each player wears a simple diving device. The game arrangement judges 3, two of them under water. Each game is 30 minutes, divided into two halves. The player can pass the ball and shoot underwater by holding the ball stick, and can float out of the water surface only when exchanging air. Foul is counted by touching the ball with hands or body. The win and loss are evaluated according to the number of goals.

The greatest weakness of underwater hockey is that without appreciation, the audience on the water cannot see the wonderful course of the game and is therefore not destined to be a commercial pet. Underwater hockey, while done underwater, does not regularly allow for overly drastic physical countermeasures. Under the protection of the resistance of water and equipment, even if a player is kicked or hit, the player is not easy to be really injured.

Through studying related videos and character introduction on the network, I draw the following defects and put forward an improvement method.

The audience watches the game from the stand to the underwater, the content is not clearly seen, and the audience can see the whole process of roughly dribbling and shooting at the same time of the game unlike the indoor football game, so the audience has poor enjoyment.

The user watches videos shot underwater through a mobile phone at home, and the user can understand a lot of videos in addition to the explanation of a professional interpreter.

The main reason for this is that the diameter of the shot of the match is too small, the position is too low, the position of the athlete is in the lying state again, from the top to the bottom, a certain instant stop-motion picture of the shot is taken, because the size of the shot of a key focus is too small, the distance between two team members is too close, and it seems that a pile of fish swims in the water, with 6+6 athletes in the lying state, the size proportion of the picture occupied in the same picture is too poor, and the distance between two team members is too close.

The solution is that the diameter of the ball is increased by 3 to 5 times, the position is improved, the ball is similar to a water ball in the suspended water, and the human body is changed from a flat lying state to an upright state for competition, so that the balls and the bats with different colors can be clearly seen.

And (II) in each time of the sport, people need to feel suffocated to attack and defend underwater, and more teammates can feel suffocated for a while and more rest.

For most of the ordinary people who will swim, if they want to experience, the first natural reaction is afraid of the mind without the guidance of regular trainers, so most people dare not to try.

The solution is as follows: the water level is reduced, and the head is exposed out of the water surface, namely, the underwater breathing and the underwater competition are realized. The gravity center is reduced, so that the roller skates can be worn underwater, and the competition activity can be carried out in more stable and upright water.

And (III) 3 game design referees, namely, two referees under water. In fact, two judges underwater have large physical consumption and easy dispersion of energy.

The solution is as follows: and a plurality of cameras are added near the two-side goal frame.

The game is provided with 4 referees, and the referees do not launch water under the ordinary condition. 2 sit at the swimming pool side, directly observe underwater match process and judge with spectator according to own naked eye together, sit before the computer in addition 2 sit, watch the goal condition of two sides, the final average scoring result of 4 referees is regarded as the final condition of scoring.

Three, underwater roller-skating hockey (fig. 3)

An underwater roller-skating hockey relates to an underwater ball-confrontation sport with resistance-reducing function and the hockey. Two underwater goals are immersed, a plurality of cameras are fixedly arranged near the two goals and are aligned to the two goals. But no referee and gatekeeper exists underwater.

The athletes of the match wear the swimming trunks with the function of reducing drag while wearing the swimming cap; the left hand wears the paddling palm; a stick which is similar to an underwater hockey stick and can swing in water is held by the right hand; double-row roller skates with two toe ends worn by both feet. And carrying out underwater motion of overwater breathing and underwater competition.

Underwater roller hockey games are usually played in ordinary swimming pools. The game ball may be a round or other suitable dribbling or shooting ball.

The water ball of the design takes the water ball which is clearly seen by the auditorium as a standard, and most athletes wear roller skates to achieve a smooth water level, namely, the water level is about 0.5 to 0.7 meter below the water surface.

The two sides of the pool are at the same depth, and the depth of water is required, one of which ensures that the head of each athlete wearing the roller skate is exposed out of the water surface, thus facilitating breathing. Secondly, the center of gravity of the body moves downwards, and the stability of the body is improved. Thirdly, the water depth is the position of the chest after the roller skate is worn, and the position is comfortable.

Two competing teams have a plurality of same persons, each team member wears related underwater necessary equipment, and 4 competition equipment referees sit above the water surface beside the water pool.

In summary, the underwater roller hockey game is such

The underwater vertical sportsman wears a swimming cap and wears a stabbed swimming suit on the body, wears a paddling palm on the left hand to paddle, holds a ball stick on the right hand to carry, pass and shoot underwater, and moves forward or backward on the body under water by pedaling with double feet and double rows of roller skates, and the like, thereby finally achieving the purpose of ball passing and shooting. Foul is counted by touching the ball with hands or body. The win and loss are evaluated according to the number of goals.

Sixthly, the degree of experience: whistle blowing knowledge for football referee

Disclosure of Invention

A water ball sport project composed of three sport elements of underwater swimming, roller skating and underwater hockey is based on underwater hockey game rules and carries out recombined safe, reasonable and interesting water sport new play (figure 3).

In the sport, each competitor wears a swimming cap, wears swimming trunks with the resistance reducing function on the body, wears a paddling middle palm on the left hand, holds a ball stick on the right hand, and wears double-row roller skates on both feet. Two groups of opponent players with different colors are equipped to carry out dribbling, passing and shooting with a bat under water, and the ball is hit into an opponent goal to obtain a plurality of scores.

In a word, the water sports is an innovative project, is suitable for the competition and entertainment sports of the masses, and has certain popular market.

The brief introduction of the main contents of underwater roller hockey is as follows

One, float, suspend and sink

Solid substances insoluble in water are known to have three states at a certain temperature:

(1) floating is where a portion of the object is exposed to the liquid surface;

f floating ═ G rho liquid > rho substance V row < V substance

(2) Suspension is the complete immersion of the object in the liquid, but not the immersion into the bottom of the container.

F floating-G rho liquid-rho substance V row-V substance

(3) Sinking is the immersion of the object in the liquid and into the bottom of the container

F float < G rho liquid < rho substance V row ═ V substance

As long as the object floats or is suspended in the liquid and is in a static state, the buoyancy borne by the object is certain equal to the gravity of the object, and the gravity of the sinking bottom is larger than the buoyancy.

The underwater ball of the underwater roller-skating hockey belongs to a suspension state. Referred to herein as a hover ball.

Second, the size and suspension position of the suspension ball

Firstly, the size of the floating ball is 3 to 5 times larger than the shot volume of the existing underwater hockey, so that the design ensures that the distance between players is pulled open by considering the conditions that the referee and the audience see dribbling, passing and shooting, and the judgment of victory or defeat is facilitated.

Secondly, the position of the suspension ball:

similar to the density change of the ball in the water ball, water and small stones with the density slightly larger than that of the water are added into the water ball floating on the water surface, so that the water ball is changed from floating on the water surface to be suspended in the water with the depth of 0.5-0.6 m below the water level, and thus, even if a player wearing the roller skates can conveniently and properly position, the player and the audience on a stand can conveniently see the competition process clearly.

Thirdly, the suspension is not floating

Experiments show that pushing an object with the same mass by using a rod is obviously smaller than pushing materials in the air when an upright person uses the rod in water.

The above results are the design requirements of the size and the density of the suspension ball.

Third, there is no referee and goalkeeper under water

The underwater hockey game is provided with 3 referees, two of which are underwater. In fact, two judges underwater have large physical consumption and easy dispersion of energy.

This is the case for underwater roller hockey games

Two competing teams each have the same number of people, each wearing the necessary equipment under water. The underwater officials and goalkeepers are not available because the body can generate a plurality of adverse reactions when people are soaked in water for a long time.

The game is provided with 4 referees, the referees do not launch water under the general condition, 2 referees sit on the side of the swimming pool and observe the referees with the audience by naked eyes, 2 referees sit in front of a computer to see the goal condition at two sides, and the scoring results of the 4 referees are the scoring condition on average at last.

According to the methods of increasing the size and the suspension position of the suspension ball and the like and the methods of underwater photography and the like, a plurality of (such as 4) referees sitting at the side of the swimming pool above the water surface are ensured as much as possible, and the referees are scientifically and reasonably judged.

The fewer players in each team, the smaller the ratio of the dribbling arms and bat seen from the water surface downwards to the area of the ball, and the clearer the picture at the moment of ball entry. However, the number of the participators in each team is too small, so that the players on the field can live for one person and two persons, the physical strength can not be consumed quickly, and the entertainment of the competition is lost.

Therefore, the clear comparison relationship of the goal pictures and the number of players in each team is a balance problem in the design.

Swimming pool, water depth and door frame

Second, making the bottom of swimming pool flat [ ]

In order to ensure that the two opposing teams are just and fairly at the same water depth position, the designed natatorium has the same depth on two sides, namely a non-gradient flat pool bottom natatorium is manufactured.

When standing in water and the water overflows the chest, the person feels the breath is bitter and bitter compared with the person in the air.

When standing in water and water flows over the chest, the water pressure mainly influences the up-and-down movement of the breast diaphragm muscle, so that the feeling of breathing is bitter compared with the feeling of breathing in the air.

Therefore, the upright person wearing the roller skates has the right depth of the water pool around the chest, and the head is ensured to be exposed out of the water, and the body weight and the mind move down like a tumbler. Is convenient for breathing on water and moving underwater.

Because the water level of the underwater roller skate is above the waist, the underwater roller skate is convenient to change into a swimming posture immediately when the underwater roller skate is in a dangerous situation of unstable standing. Also can move forward, backward, rotate and the like in a swimming way by wearing the roller skates according to personal preference.

This is a balancing problem of the total weight of the skate in water and the position of the center of gravity of an upright person.

In the process of the underwater roller skating experiment (I), the experimenter feels that after the roller skating shoe is immersed in water, the foot becomes heavy, the gravity center moves downwards roughly, and the posture of swimming cannot be changed.

Goal frame:

on both sides of the swimming pool, a goal frame suitable for the suspended ball shooting is respectively arranged, and the goal frame is similar to a football or a water ball. In short, the goal frame is installed on both sides of the bottom of the swimming pool, and is not easy to move (fixed or not fixed according to specific conditions) in the game.

In order to increase the identification of whether a goal is played, two colors with obvious contrast are used for paving tiles used in a goal area at the bottom of a pool and the outside of the tile, so that people can see whether a goal boundary line exists in clear water as much as possible, and underwater shooting record and correct judgment of a judge are facilitated.

Rules of underwater goal

The competition method comprises the following steps:

underwater roller hockey games, two opposing ball pairs launch simultaneously, and then each team stands near his goal to begin the game.

Each team consists of a plurality of athletes (such as 5 or 6), and underwater goalkeepers. The game is divided into an upper half and a lower half, and each half is for a plurality of minutes. The goal is to attack the ball into the goal of the other side, and the team with more goals wins.

Fifthly, two methods for shifting gravity center downwards

In order to prevent the roller skater from slipping easily due to the fact that the roller skater is light in head and heavy in feet inside the water pool. According to the principle that the gravity center of the tumbler toy moves downwards to improve stability, an upright person is required to keep an upright, safe and stable state as much as possible in the process of skidding in water.

There are two main methods for improving stability by moving down the center of gravity

The method comprises the following steps: wear the heavy roller skate.

The second method comprises the following steps: a swimming ring is sleeved on the arm or a small floating plate is tied on the waist.

The gravity center moves downwards, so that the people who upright and roll on the water can keep a relatively stable upright posture as much as possible to play the competition, the people can breathe on the water conveniently, and the clear competition mind can be kept.

Sixthly, main water equipment

The equipment required for the game is at least 5: (1) the swimming cap (2) is a split type barbed swimming suit (3), a paddling palm (4) and an underwater bat (5) are provided with double-row roller skates. The detailed description is as follows

(1) Swimming cap

To improve the hygiene of individuals and swimming pools, competitors are required to perform aquatic activities with swimming caps, as in other aquatic sports.

(2) Split type thorn swimsuit

Because the density of water is about 800 times of that of air, in order to reduce resistance and increase sliding speed, the appearance characteristics of the small spines in the figures 6 and 7 are referred, and then a plurality of rows of conical small spines with proper sizes are added outside the common split swimwear (or diving suit), and the shapes of the small spines are similar to the shapes of cactus with spines, sea cucumbers with spines and the like.

(3) Strike water palm (Picture 5)

Through underwater tests, people know that the speed of paddling by wearing the paddling palm is greatly increased compared with that of paddling by bare hands (the paddling palm).

(4) Underwater bat

The suspension ball of the design must be placed below the water surface.

Experiments show that the force of the bat pushing the floating ball in water is far less than the force of the bat pushing the ball with the same mass in air. Therefore, the ball pushing in the water is labor-saving.

Based on the underwater hockey stick, the underwater hockey stick of the match type floating ball is modified according to the conditions of a specific venue and the like.

The selection of the utility model not only ensures the safety, reliability, durability, economy and reasonability of the structure, but also makes the player to carry and shoot the ball smoothly, and the referee and the audience on the table look clearly.

(3) Double-row roller skate

The experimental results are as follows: under water, the common double-row roller skating is more stable than the single-row roller skating.

In order to reduce resistance and increase sliding speed, the appearance characteristics of the double-row roller skates with two pointed ends are changed on the basis of the existing common double-row roller skates on the premise of not influencing various underwater sliding requirements. And others:

nose clip:

the inventor considers that the beginners press the body of the swimming pool to squat deeply and tilt forwards to increase the speed of skidding in water, and the water in the swimming pool is pressed into the swimming pool from the nose hole suddenly.

So a nose clip (with or without as the case may be) provided for a water ballet to prevent the nose from entering water in case of an emergency.

(7) Order of race movement

The whistle is the main signal of the referee to lead the competition, and is the command of the competition going to the end, whether the whistle is accurate and timely, and whether the whole competition can be smoothly carried out or not.

The main command signal used by the referee can also be a whistle or other water sports equipment.

And (4) period.

Detailed Description

Underwater wheel slide experiment 1

In 11 months 2021, we performed experiments in a common swimming pool in the Shanghai with the help of the relevant departments. The water depth of the swimming pool is 0.9 m-1.5. m, please a sports enthusiast as an experimenter.

The main contents of the experiment

Function of the first water-skiing palm

The experimenters wear or do not wear the paddling palm in the swimming pool with the skating shoes, and the experimental result shows that, under the condition, the paddling palm of the underwater vertical roller skating has the function of accelerating the advancing speed. In the water depth range experiment of the swimming pool, in a pool of 0.9m, an experimenter feels that water is too shallow, so that the buoyancy of the water is not large, the water is not safe and interesting, and the feeling is better when the experimenter goes to a deep place. When the upright person wears the roller skates, the water depth reaches the positions around the chest part to do various underwater exercises, and the person is preliminarily considered to be a comfortable water depth position.

(II) double-row roller skate

Roller skating is an interesting tool for riding instead of walk, and single-row roller skating and double-row roller skating are discussed. Double row roller skateboarding plays on a smooth wooden floor in a room as fast as a single row, then in water?

The experimental results are as follows: under water, the double-row roller skating is more stable than the single-row roller skating.

(III) two methods for moving down center of gravity

In order to prevent the roller skater from slipping easily due to the fact that the roller skater is light in head and heavy in feet inside the water pool. According to the principle that the gravity center of the tumbler toy moves downwards to improve stability, an upright person is required to keep an upright, safe and stable state as much as possible in the process of skidding in water. There are two methods for improving stability by moving down center of gravity

The method comprises the following steps: wear the heavy roller skate.

(in this experiment, the experimenter felt that the ordinary roller skate under the body was too heavy to swim well after being soaked in water)

The second method comprises the following steps: a small back floating plate (with or without a floating plate, which can be used according to individual conditions in the test and is not used) is tied on the arm sleeve or the waist.
