specific Embodiment approach 1

[0023] Specific implementation mode one: combine Figure 1 to Figure 4 Describe this embodiment, this embodiment

[0024] The non-contact water polo shooting training device based on the pressure sensor is characterized in that it includes a goal 1, an electric control device 5 and an image projection system 6;

[0025] The goal 1 includes an outer frame 11 and a water polo baffle 12 with M pressure sensors 7, the value of M is a positive integer; the outer frame 11 is the outer frame of the water polo goal, and the goal baffle 12 is installed At the rear of the outer frame 11, the M pressure sensors 7 are evenly distributed on the goal stopper 12,

[0026] The goal stopper 12 is a sheet with a thickness, and the goal stopper 12 is composed of a surface layer 121, an elastic layer 122, a pressure sensor fixing layer 123 and a bottom layer 124.

[0027] The edges of the bottom layer 124 and the surface layer 121 are fixedly connected to form a hollow bag, the pressure sensor ...

specific Embodiment approach 2

[0048] Specific implementation mode two: combination figure 2 This embodiment is described. The difference between this embodiment and the above-mentioned specific embodiments is that each pressure sensor 7 is provided with a protective cover 126 . Other compositions and connection modes are the same as the above-mentioned specific embodiment. The protective cover 126 added in this embodiment is used to protect the pressure sensor 7 . Each pressure sensor 7 is arranged in the protective sleeve 126, and the deformation index of the protective sleeve 126 is the maximum bearing capacity of the pressure sensor 7, so as to avoid overload damage of the pressure sensor 7.

Abstract

A non-contact-type water polo shooting training device based on a pressure transducer relates to training equipment, solves the problem that the intensive training of athletes is restricted since the number of goalkeepers is too few at present, and overcomes the defect that the movement information about explosive forces of upper limbs of athletes in shooting cannot be gathered in training. The non-contact-type water polo shooting training device comprises a goal, an electric control unit and an image projection system, wherein the goal comprises an outline border and a water polo baffle with the pressure transducer; the water polo baffle is a thick flap including a surface layer, an elastic layer, a pressure transducer fixed layer and a bottom layer; a pressure signal output end of the pressure transducer is connected with a pressure signal input end of the electric control unit; a projected image data signal output end of the electric control unit is connected with a projected image data signal input end of an image data processing device; and a drop point image data signal input end of the electric control unit is connected with a drop point image data input end of the image data processing device. The non-contact-type water polo shooting training device is suitable for gathering the movement information about explosive forces of upper limbs of athletes in shooting.

Description

technical field [0001] The invention relates to training equipment, in particular to a water polo shooting training device. Background technique [0002] At present, in water polo shooting training, the training method adopted is to carry out shooting practice on a goal with a goalkeeper in turn with teammates. Restricted by the small number of goalkeepers, it is impossible to carry out a lot of intensive training on shooting, which reduces the effect of water polo shooting training. And, also there is water polo training process and can't collect and obtain the movement information of athlete's upper limb shooting explosive power, make the team member can't know the shooting speed of shooting in training process. There is a lack of light reaction exercises combined with water polo special training and exercises when choosing reactions. Water polo competitions are intense and varied, so athletes are required to have extremely fast responses and good adaptability. Existing...
