Embodiment Construction

[0080] Theoretical basis:

[0081] ① Sogou Encyclopedia: Air Density

[0082] Air density refers to the mass of a unit volume of air at a certain temperature and pressure. Under standard conditions (0°C, 1 standard atmospheric pressure (1atm)), the air density is about 1.293Kg / m 3 . ②Avanti.com: What is the physical meaning of the density of water being 1000kg / m3?

[0083] Answer: The density of water is 1.0×103kg / m3, which means that the physical meaning is: the mass of water with a volume of 1m3 is 1.0×103kg. Density and its characteristics

[0084] 1000: 1.293 = 773.395205

[0085] Therefore, the ratio of the density of water to the density of air is 773.395205 (times).

[0086] ③Sogou asks: The area of ​​a thumbtack cap is 0.8cm2, and the area of ​​the top of the picture is 5×10-4cm2 The pressure is 40N, how many Pa are the pressures of the hand on the cap of the thumbtack and the pressure on the wall by the tip of the thumbtack? The ratio of the pressure P2 exerted...

Abstract

The invention relates to a suspended water polo in a swimming pool, in particular to a suspended water polo which is manufactured in an experience type flat-bottom swimming pool with the characteristics similar to those of a common flat-bottom swimming pool according to the requirement of suspending at a certain water level. The water polo is a point-to-point series water polo which is selected and modified according to the requirements of the drawing pin pressure reduction principle, the appearance structure, the water polo stress condition, the balance factor and the like. A participant wears a pressure-reducing swimming cap on the head, and wears a pressure-reducing long sleeve, a pair of trousers swimsuit, barefoot or roller skate on the body. In the experiential swimming pool, the user can breathe on water and play the ball underwater in an upright state, so that the user can breathe on water and play the ball underwater with certain interestingness and ornamental value. A suspended water polo in a swimming pool is mainly used in the following three exercises: (1) one person aims at ceramic tile walls on four sides of the swimming pool to play a ball (in an allowed experience type swimming pool); and (2) single-shot (two face-to-face erectors) or double-shot (four face-to-face erectors). And (3) competition balls (10 erectors, 5: 5) of the roller skating hockey.

Description

technical field [0001] The invention of this application relates to a suspended water polo in a swimming pool, which belongs to the technical scheme of the method invention patent in the field of "necessary for human life" entertainment products ( image 3 ). Background technique [0002] Badminton (or volleyball) is a very popular sport. In short, it is such a motion state: [0003] Athlete A and Athlete B are about 4-5 meters away from each other, and they are facing each other in an upright position.

[0004] A suspended water polo in a swimming pool is to change this ground sport from the ground to be carried out in an experiential flat-bottomed swimming pool. The ball used for water fitness ( ...
