[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0031] Reference Figure 1 - Figure 3The utility model provides an embodiment: a self-generating buoy at sea, including a buoy body 1. The buoy body 1 is a prior art.

They can indicate the safe route for ships to sail, help ships avoid obstacles and shoals, and provide navigation references, which helps to ensure the safety and smoothness of maritime traffic. Since it is a prior art, workers in this field understand how to use it, so it will not be introduced in detail. A rectangular groove 5 is provided at the bottom end of the front surface of the buoy body 1, and a power generation component 3 is provided on the lower surface of the buoy body 1. A through hole 2 is provided on the upper surface of the buoy body 1, through which a wire 34 can be pulled out, and the wire 34 is connected to the equipment on the buoy body 1 and the battery holder, thereby improving practicality. The outer wall at the top of the power generation component 3 is provided with a mounting component 4. The power generation component 3 includes a columnar bracket 31, and the columnar bracket 31 is set as a leak hole to ensure that the water flow generated by the waves can directly generate an impact force on the vibrator 33, thereby improving its practicality. Vibration effect, the upper surface of the cylindrical bracket 31 contacts the lower surface of the buoy body 1, and the front surface of the cylindrical bracket 31 is penetrated and fixedly connected with a ring 32, and the inner wall of the ring 32 is fixedly connected with a piezoelectric ceramic 35. The piezoelectric ceramic 35 is a prior art and is a ceramic material with a piezoelectric effect. The piezoelectric effect refers to the charge separation phenomenon that occurs when certain crystal materials are subjected to mechanical stress, thereby generating a voltage on the surface of the material. This effect is caused by changes in the dielectric structure inside the crystal. In this way, the purpose of converting mechanical energy into electrical energy can be achieved. The inner wall of the ring 32 is set to a hexagon, and each surface of the hexagon is set with a spring 36 and a piezoelectric ceramic 35 to ensure that it can accept multi-faceted natural forces and improve the efficiency of self-generation.
[0032] Reference Figure 1 - Figure 2 , Figure 5 The mounting assembly 4 includes a fixing seat 42, which is fixedly connected to the outer wall at the top of the columnar bracket 31.

The buoyancy ring 43 has a certain buoyancy to ensure that when the power generation assembly 3 needs to be repaired in the later stage, there is no need to disassemble the entire buoy body 1, thereby improving convenience. The upper surface of the fixing seat 42 contacts the lower surface of the buoy body 1, and the upper surface of the fixing seat 42 is slidably connected to a ring block 41.
[0033] Reference Figure 2 - Figure 4, a wire 34 is fixedly connected to the rear surface of the ring 32 through the ring 32. The wire 34 is a prior art, and multiple groups of wires are provided. One end of the multiple groups of wires 34 is connected to the piezoelectric ceramic 35, and the other end of the multiple groups of wires 34 is connected to the equipment and the battery on the buoy body 1. Since it is a prior art, the staff in this field are familiar with the connection method of the wire 34, so it will not be shown and explained in detail. The front end of the wire 34 is fixedly connected to the upper surface of the piezoelectric ceramic 35, and the lower surface of the piezoelectric ceramic 35 is elastically connected to the vibrator 33 through a spring 36. The spring 36 itself has a certain elasticity. When the vibrator is affected by the vortex-induced vibration effect and vibrates, the spring 36 will The vibration effect is enhanced by its own elasticity. One end of spring 36 is fixedly connected to the lower surface of piezoelectric ceramic 35, and the other end of spring 36 is fixedly connected to the upper surface of the front end of vibrator 33. There are multiple groups of piezoelectric ceramics 35 and spring 36, and the multiple groups of piezoelectric ceramics 35 and spring 36 are arranged in a circular array with the center of the ring 32 as the origin. The multiple groups can improve the power generation effect. At the same time, there are also multiple groups of ring 32, vibrator 33, wire 34, piezoelectric ceramics 35, and spring 36, which are evenly distributed on the inner wall of the columnar bracket 31. At the same time, the angles of the multiple groups of vibrators 33 are different, which can ensure that the power generation component 3 can absorb natural forces at different angles, thereby improving practicality.
[0034] Reference Figure 2 , Figure 5 A through groove 1 44 is provided on the upper surface of the annular block 41, and the through groove 1 44 has a certain slope to ensure that when the annular block 41 is rotated, the round rod 45 can move along its slope, and a through groove 2 46 is provided on the upper surface of the fixed seat 42, and the round rod 45 is slidably connected inside the through groove 2 46, and the outer wall of the top end of the round rod 45 is slidably connected to the inner wall of the through groove 1 44, and the inner wall of the front end of the fixed seat 42 is elastically connected to a block 47 through a spring 2 48, and the block 47 is slidably connected to the inner wall of the front end of the fixed seat 42, and one end of the spring 2 48 is fixedly connected to the inner wall of the front end of the fixed seat 42, and the spring 2 48 always pushes the block 47 to move backward through its own elasticity to ensure its limit stability, and the other end of the spring 2 48 is fixedly connected to the front surface of the block 47, and the lower surface of the round rod 45 is fixedly connected to the front end of the upper surface of the block 47, and the rear surface of the block 47 is set to an inclined surface, and the set inclined surface can improve the installation efficiency of the power generation component 3.
[0035] Working principle: When in use, the power generation component 3 is installed at the bottom of the buoy body 1, and the wire 34 is connected to the equipment or battery installed on the buoy body 1. When the buoy body 1 is impacted by waves, the vortex-induced vibration effect generated will cause the vibrator 33 to vibrate, and the vibrator 33 will squeeze the spring 36. The spring 36 will squeeze the piezoelectric ceramic 35 through its own elastic reaction force. At this time, the piezoelectric ceramic 35 will generate electrical energy through its own piezoelectric effect. At this time, the electrical energy will be transmitted to the equipment or battery on the buoy body 1 through the wire 34, ensuring that the equipment on the buoy body 1 can be used normally at sea, thereby improving practicality. Multiple groups of rings 32, vibrators 33, wires 34, piezoelectric ceramics 35, and springs 36 are arranged, and the multiple groups are evenly distributed on the inner wall of the columnar bracket 31. At the same time, the angles of the vibrators 33 in each group are different, ensuring that natural forces in different directions can be received, thereby improving the power generation effect.
[0036] The buoyancy ring 43 is set to allow the power generation component 3 to float on the sea surface when it is not installed on the buoy body 1. Therefore, when the power generation component 3 is repaired in the later stage, there is no need to disassemble the entire buoy body 1. The power generation component 3 can be installed and disassembled on the sea surface, which improves practicality. When installing, it is only necessary to move the fixing seat 42 to the bottom of the buoy body 1. At this time, the buoyancy of the buoyancy ring 43 will drive the fixing seat 42 to move upward, and the buoy body 1 will push it to move along the inclined surface of the block 47. The block 47 will squeeze the spring 48, and at the same time the block 47 will drive the round rod 45 to move. The round rod 45 slides on the inner wall of the through groove 1 44 and drives the annular block along the inclination of the through groove 1 44. 41 is rotated until the block 47 overlaps with the rectangular groove 5. At this time, the spring 2 48 will push the block 47 to move in the direction and insert into the inner wall of the rectangular groove 5 through its own elasticity, and the round rod 45 and the annular block 41 will also move in the opposite direction to reset. In this way, the installation is successful, quick and convenient. After the installation is completed, the wire 34 can be connected to the equipment and battery set on the buoy body 1 through the opened through hole 2. When disassembling, it is necessary to remove the wire 34, and then rotate the annular block 41. The round rod 45 drives the block 47 to move along the inclined surface of the through groove 1 44, so that the block 47 is separated from the inner wall of the rectangular groove 5, and then the fixing seat 42 is pressed downward to separate it from the buoy body 1. In this way, the disassembly can be completed, which improves practicality.
