[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Example: An adjustable buoyancy training surfboard, please see below. Figures 1 to 5As shown, the surfboard includes a surfboard body 1, a front skid plate 2, a rear skid plate 3, a tail fin 4, a buoyancy adjustment frame 5, a stopper 6, a divider 7, a connecting rope 8, foot straps 9, an alarm 10, a test ring 11, and side strips 12. The surfboard body 1 serves as the main structure of the training surfboard, bearing the surfer's weight and providing a surfing platform. The left side of the surfboard body 1 is the nose, and the right side is the tail. The surfboard body 1 has a long, flat shape. The front skid plate 2 is connected to the top left side of the surfboard body 1. The front skid plate 2 is used to increase buoyancy. To enhance stability and grip at the nose of the surfboard, a rear skid plate 3 is attached to the top right side of the surfboard body 1. The rear skid plate 3 increases stability and grip at the tail. A tail fin 4 is symmetrically attached to the front and rear of the bottom right side of the surfboard body 1. The tail fin 4 provides stability and steering ability in the water. A buoyancy adjustment frame 5 is attached to the bottom of the surfboard body 1. The interior of the buoyancy adjustment frame 5 is symmetrically connected to the left and right sides by partitions 7, dividing the interior of the buoyancy adjustment frame 5 into three independent compartments for more precise buoyancy adjustment. The buoyancy of the surfboard is adjusted by changing the water volume in the three compartments, thus adapting to the needs of different surfers and different water conditions. Water inlets are evenly spaced at the bottom of the buoyancy adjustment frame 5, located at the bottom of each of the three compartments. Each inlet is fitted with a plug 6 to seal it. Adding water to the three compartments of the buoyancy adjustment frame 5 adjusts the buoyancy of the surfboard body 1. A connecting rope 8 is attached to the right side of the surfboard body 1, and a foot strap 9 is attached to the other end of the connecting rope 8. To secure the surfer's feet and prevent them from losing their balance and falling off the surfboard body 1 during surfing, an alarm 10 is installed on the right side of the surfboard body 1. A test ring 11 is connected to the right side of the alarm 10 and is connected to one end of the connecting rope 8. When the connecting rope 8 is broken, the test ring 11 can send a signal to the alarm 10, thereby causing the alarm 10 to sound an alarm and transmit a signal to relevant personnel. A board edge strip 12 is connected to the top edge of the surfboard body 1 to increase the durability and aesthetics of the surfboard body 1 or to provide a certain grip.
[0022] When using a training surfboard, the first step is to adjust the surfboard's buoyancy through the water inlet on the buoyancy adjustment box 5, based on individual needs and current water conditions. The specific steps are as follows: First, open the stopper 6 and add an appropriate amount of water to the first buoyancy adjustment box 5 from the left. This increases the weight of the surfboard's nose, making the surfboard more stable during riding. Add water to the second buoyancy adjustment box 5 to balance the weight of the surfboard's body. This helps the surfer maintain balance while surfing. If a heavier tail is needed for maneuvering, add water to the third buoyancy adjustment box 5. This makes it easier for the surfboard to nose-up during riding, meeting the demands of maneuvers. After adding the appropriate amount of water, close the stopper 6 again. It is important to note that buoyancy adjustments should be made based on the surfer's weight, skill level, and desired surfing experience to ensure both safety and enjoyment.
[0023] Next, place the surfboard body 1 in the water or on the beach, ensuring the nose of the board faces the direction the surfer intends to enter. The surfer stands on the surfboard body 1, threading their feet through the connecting rope 8 and securing them to the foot straps 9. Make sure the foot straps 9 are secure but not too tight, providing sufficient support while maintaining comfort.
[0024] In addition, it is necessary to ensure that the alarm 10 and test ring 11 are in normal working order. The test ring 11 should be securely connected to one end of the connecting rope 8 so that the alarm can be triggered quickly in an emergency. If there is any other safety equipment, it should also be worn or ready at this time.
[0025] When surfing, surfers should choose the appropriate time and angle based on the wave conditions, utilizing the stability and steering ability provided by the tail fin 4 to paddle into the wave. Maintaining body balance is crucial during surfing, and the anti-slip properties provided by the front skid 2 and rear skid 3 can be used to increase stability.
[0026] In case of danger, surfers should immediately pull the connecting rope 8 to trigger the alarm 10, while remaining calm and taking self-rescue measures.
[0027] After surfing, tow the surfboard back to shore or a safe area. Afterward, keep the surfboard clean and dry, avoiding prolonged exposure to sunlight or moisture. When storing, place the surfboard in a flat, dry, and well-ventilated location, avoiding heavy pressure or squeezing to ensure its durability and performance.
[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
