Detailed Description

For ease of understanding, the specific structure and operation of the present utility model will be further described herein with reference to FIGS. 1-4:

the specific structure of the utility model is shown in figures 1-4, and the main structure of the utility model comprises a table body 10; the table body 10 is a square frame body structure shown in fig. 1-2. The table body 10 is built with a receiving tank 20 so as to receive a foam granular or sheet-shaped floating body.

As can be seen in fig. 1-2, the receiving reservoir 20 itself is square-shaped with its opening facing upwards and is formed by a combination of plastic sheeting 22 and a base plate 21. The plastic guard plate 22 is square sleeve-shaped, and the direct axis line is vertically erected in the box cavity of the square box-shaped bottom plate 21 during assembly. Mounting holes 21a are provided in the base plate 21 to assemble the blower assembly 30 point by point as shown in fig. 3-4.

The blowing assembly 30 has two possible embodiments, one is to directly use a fan to form the wind source 31, and rely on the wind tube 32 with the radial partition plate 32a and the steel wire mesh type blocking net 33, and after the installation is completed by the corresponding fastening bolts 34a and the fastening nuts 34b, the overall assembly effect as shown in fig. 3 can be achieved. Secondly, a compressed air source such as a compressed air bottle is used as an air source 31, and a wind barrel 32 with a radial partition plate 32a and a steel wire mesh type blocking net 33 are matched, so that a set blowing effect can be realized. In actual assembly, the wind tunnel 32 may be fitted to the bottom plate 21 through the second spigot 32b to clamp the blocking net 33, thereby forming an assembled state as shown in fig. 3. Meanwhile, when the blowing component blows air, the maximum value of the wind force is required to be paid attention to, so that the floating body is prevented from being blown up too high to be excessively dissipated out of the receiving range of the accommodating pool 20.

When the blower assembly 30 is mounted on the base plate 21, the benefits of the upwardly bent outer edge of the base plate 21 to integrally form a box-like structure with the mouth facing upward can be seen in fig. 1-2: the outer edge of the bottom plate 21 is bent upwards, so that the actual position of the plastic guard plate 22 can be limited, and excessive horizontal displacement of the plastic guard plate is avoided; meanwhile, the plastic guard plate 22 ensures that the bottom plate 21 does not generate excessive horizontal displacement by virtue of the cooperation of the first spigot 22a and the table body 10; after the two are nested with each other, the inherent accommodating function of the accommodating pool 20 can be realized without installing additional fasteners, the effect is remarkable, and the cost performance is higher.

In practical design, a motion capture camera, such as a kinect2.0 camera, can be separately arranged above the platform body 10 to form an interactive system, so as to match with an electric control module and the like to realize the control effect on the wind power of the blowing component 30 and whether to blow. The projector 40 can be arranged as shown in fig. 1-2, the projector 40 projects a high simulation picture to be beaten in the accommodation pool 20 below, so that the attention of a participant is more easily attracted, the participation emotion is induced, and the simulation degree can be further improved; or both may be provided. Of course, the interactive system is simply a hardware platform consisting of physical components connected together by wiring. In use, the interactive system can be used in combination with prior art software to control the blower assembly 30, such dynamic capture software is well established and even commercially available. In other words, the protection of the present utility model extends only to a hardware network consisting of physical components and wires, and does not involve modification and protection of existing software, as described herein.

To facilitate a further understanding of the present utility model, one of the working conditions of the utility model is presented herein in connection with FIGS. 1-4 as follows:

after the utility model is installed, the power supply is turned on, and at the moment, the motion capture camera and the projector 40 are synchronously turned on, and the motion capture camera captures the table information of the table body 10 at any time. When the participant is engaged, his limb is waving over the holding tank 20, the motion capture camera can capture the waving position information of the limb and then send the information to the electronic control module, which then maps the information to the blowing assembly 30 at the bottom of the holding tank 20. When the wind source 31 of the blowing component 30 is a fan, the fan is turned on or off, or the wind power is increased or decreased according to the limb frequency; when the air source 31 of the air blowing component 30 is a compressed air source, the air valve switch realizes the opening and closing actions, or the wind power is regulated through the flow valve. When the foam granular or sheet-shaped floating body is expressed in the accommodating pool 20, the foam granular or sheet-shaped floating body in the accommodating pool 20 flies upwards under the action of wind flow, and naturally falls back to the accommodating pool 20 after being separated from the wind flow or the wind flow is reduced to a certain degree, so that interactive operation is realized. Meanwhile, the projector 40 can also emit corresponding pictures in corresponding areas to give particle effects so as to improve interaction quality.
