Description

Technical Field

[0001] This utility model relates to the field of amusement equipment technology, specifically a wave-making ball. Background Technology

[0002] In the field of artificial wave generation, the current mainstream technologies generally employ vacuum energy storage wave generation systems and wind turbine-driven wave generation devices. While both of these technologies can achieve effective wave generation, they both face the problems of large equipment investment and high operation and maintenance costs.

[0003] Currently, there are some wave-generating balls on the market used to create artificial waves. Chinese Utility Model Patent Application No. CN201620277658.1 discloses an artificial wave-generating ball device, including a hollow sphere that gradually expands outward from the top and gradually contracts inward from the bottom. The outer surface of the bottom of the sphere is an arc surface extending circumferentially around the center line of the sphere. Inside the sphere is a mounting plate, a cylinder fixed to the mounting plate, and a counterweight driven by the cylinder. This artificial wave-generating ball device uses a cylinder to drive the counterweight in reciprocating motion, resulting in high energy consumption; at the same time, its wave generation efficiency is relatively low due to the limitation of the cylinder's stroke speed.

[0004] Therefore, it is necessary to propose a wave-generating ball to solve the above problems. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] The purpose of this invention is to provide a wave-generating ball to solve the problems of high energy consumption and limited wave-generating effect of existing wave-generating balls mentioned in the background art.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a wave-generating ball comprising a sphere, with a top plate and a bottom plate fixedly connected to the top and bottom ends of the sphere, respectively. A counterweight is suspended below the top plate by a tension spring, and a guide rod is vertically fixedly connected to the bottom plate. The counterweight is slidably connected to the guide rod. A linear drive mechanism is provided between the top plate and the counterweight. The linear drive mechanism drives the counterweight downward for energy storage in the tension spring. When the counterweight reaches its extreme position, the tension spring releases the stored energy and drives the counterweight upward to reset.

[0009] Preferably, the linear drive mechanism is a cylinder, the cylinder body is fixedly connected to the counterweight, and the piston rod of the cylinder is hinged to the top plate.

[0010] Preferably, the linear drive mechanism is collinear with the axis of the ball, and there are multiple tension springs, which are distributed in a circumferential array along the linear drive mechanism.

[0011] Preferably, the two ends of the tension spring are fixedly connected to the top plate and the counterweight respectively through spring seats. The spring seat includes a movable bracket and a fixed bracket. The movable bracket and the fixed bracket are each provided with a groove adapted to the tension spring on the side adjacent to each other.

[0012] Preferably, the guide rod is slidably connected to the counterweight via a graphite copper sleeve, and the graphite copper sleeve passes through the counterweight and is fixedly connected to the counterweight via an elastic retaining ring.

[0013] Preferably, both the top plate and the bottom plate are fixedly connected to the inside of the sphere.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, the present invention provides a wave-generating ball with the following beneficial effects:

[0019] This wave-making ball uses a linear drive mechanism to drive the counterweight downwards and a tension spring to drive the counterweight upwards. When the counterweight makes a reciprocating motion, only the linear drive mechanism needs to drive it in one direction, reducing energy consumption. At the same time, the tension spring drives the counterweight to accelerate upwards, increasing the overall apparent weight so that the ball pushes the liquid surface to generate waves, thus improving the wave-making effect.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Please see Figures 1-4 As shown, a wave-generating ball includes a ball 2, with a top plate 1 and a bottom plate 8 fixedly connected to the top and bottom of the ball 2, respectively. A counterweight 6 is suspended below the top plate 1 by a tension spring 4. A guide rod 7 is vertically fixedly connected to the bottom plate 8, and the counterweight 6 is slidably connected to the guide rod 7. A linear drive mechanism 10 is provided between the top plate 1 and the counterweight 6. The linear drive mechanism 10 drives the counterweight 6 downward to store energy in the tension spring 4. When the counterweight 6 descends to its limit position, the tension spring 4 releases the stored energy and drives the counterweight 6 upward to reset.

[0027] In use, the sphere 2 is placed on the water surface, and the counterweight 6 is driven downward by the linear drive mechanism 10. The tension spring 4 is stretched. When the counterweight 6 reaches its extreme position, the tension spring 4 releases its stored energy and drives the counterweight 6 to quickly rise and reset, thus repeating the cycle. The counterweight 6 moves up and down inside the sphere 2, causing the sphere 2 to float up and down, resulting in periodic fluctuations in the liquid surface and generating waves. Specifically, when the tension spring 4 contracts, the counterweight 6 accelerates upward, increasing its overall apparent weight, causing the sphere 2 to sink, displacing liquid and causing surface fluctuations. Preferably, the lower end face of the sphere 2 is flat to increase the contact area with the liquid surface and prevent rolling.

[0028] Specifically, the linear drive mechanism 10 is a cylinder, with the cylinder body fixedly connected to the counterweight 6 and the piston rod hinged to the top plate 1. When the cylinder extends, it drives the counterweight 6 downward. After reaching its limit position, the cylinder exhausts air, and the tension spring 4 drives the counterweight 6 to return to its original position. Preferably, a buffer block 9 is fixedly connected to the cylinder body, and the buffer block 9 is sleeved on the outside of the piston rod. By setting the buffer block 9, the piston rod is buffered, preventing it from hitting the end face of the cylinder body when it moves to the end of its stroke.

[0029] In order to ensure that the counterweight 6 is subjected to uniform force and to make it move up and down in a stable manner, the linear drive mechanism 10 is collinear with the axis of the ball 2, and there are multiple tension springs 4, which are distributed in a circumferential array along the linear drive mechanism 10.

[0030] In some embodiments, the two ends of the tension spring 4 are fixedly connected to the top plate 1 and the counterweight 6 respectively via spring seats 5. The spring seat 5 includes a movable retainer 19 and a fixed retainer 20. The movable retainer 19 and the fixed retainer 20 are each provided with a groove 18 adapted to the tension spring 4 on their adjacent sides. When assembling the tension spring 4, the movable retainer 19 and the fixed retainer 20 clamp and fix the ends of the tension spring 4, and at the same time, the stability of the connection is enhanced by the action of the groove 18.

[0031] To reduce the coefficient of friction and wear, the guide rod 7 is slidably connected to the counterweight 6 via a graphite copper sleeve 11. The graphite copper sleeve 11 passes through the counterweight 6 and is fixedly connected to the counterweight 6 via an elastic retaining ring 21. The elastic retaining ring 21 connects the graphite copper sleeve 11 to the counterweight 6, making it easy to disassemble and install for maintenance and replacement. Preferably, the position of the guide rod 7 corresponds to the position of the tension spring 4.

[0032] Specifically, the top plate 1 and the bottom plate 8 are both fixedly connected to the inner side of the sphere 2. An upper positioning plate 17 is provided on the outer side of the top of the sphere 2, and the upper positioning plate 17 is fixedly connected to the top plate 1 by bolts. The top plate 1 and the upper positioning plate 17 cooperate to clamp the wall of the sphere 2, thereby increasing the force-bearing area of ​​the sphere 2 and preventing damage to the sphere 2. Similarly, a lower positioning plate 13 is provided on the outer side of the bottom of the sphere 2, and the bottom plate 8 and the lower positioning plate 13 cooperate to clamp the wall of the sphere 2, increasing the force-bearing area of ​​the sphere 2 and preventing damage to the sphere 2. A lifting ring is fixedly connected to the top of the upper positioning plate 17 for lifting the sphere 2.

[0033] Multiple elastic ribs 3 are fixedly connected to the outer side of the top plate 1 along its circumference. When the counterweight 6 moves up and down, the elastic ribs 3 can increase the force-bearing area of ​​the sphere 2.

[0034] In some embodiments, a pipe clamp 14 and a rotating lifting ring 15 are fixedly connected to the lower positioning plate 13, and a sealing sleeve 12 is provided at the center of the bottom end of the sphere 2. By providing the rotating lifting ring 15, during use, one end of the traction rope is connected to the rotating lifting ring 15, and the other end of the traction rope is fixed to the bottom of the pool. The traction rope constrains the sphere 2, limiting the lateral displacement of the sphere 2. The air supply pipeline of the cylinder is fixed by the pipe clamp 14, and then the air supply pipeline is passed through the sealing sleeve 12 into the interior of the sphere 2 and connected to the cylinder. Under the sealing of the sealing sleeve 12, liquid is prevented from entering the sphere 2, and under the action of the pipe clamp 14, the air supply pipeline is prevented from falling off.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
