Description

[0001] This invention relates to the field of wireless communication, specifically a buoy communication device based on satellite communication. Background Technology

[0002] Marine buoy communication devices, in conjunction with satellite communication, transmit marine monitoring data to land wirelessly. This marine monitoring data generally includes meteorological data, hydrological data, ecological indicators, and pollution monitoring data. Furthermore, it can provide high-precision positioning services through the BeiDou satellite system, enabling buoys to update their location information in real time, improving the efficiency and accuracy of marine monitoring. At the same time, it can realize data transmission and information sharing between marine buoys, enhancing the ability of maritime emergency rescue.

[0003] With the development of technology, the transmission rate of satellite-based buoy communication devices is constantly improving and the latency is decreasing, enabling them to receive the latest data in the shortest possible time.

However, there are many days of cloudy and rainy weather at sea, during which the efficiency of photovoltaic power generation is low and cannot provide sufficient power for these energy-intensive buoy communication devices. In the case of insufficient power, the buoy communication devices will enter a dormant state, suspending the transmission of marine monitoring data, which will have a negative impact on the subsequent operation.

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] Reference Figure 1 - Figure 8 A satellite-based buoy communication device includes a buoy body 1 and a communication body 2 mounted on the buoy body 1. The buoy body 1 includes a top cover 3, a middle hull 4, and a bottom counterweight 5. A photovoltaic panel 37 is installed on the top cover 3 to provide power to the communication body 2. Multiple rings of floats 38 are arranged around the outer edge of the hull 4 to keep the entire buoy communication device afloat on the sea surface. The communication body 2 is mounted on the top cover 3. A power generation component is installed between the hull 4 and the counterweight 5 to provide power to the communication body 2. The counterweight 5 includes a pull rod 6. A counterweight 7 is provided at the lower end of the pull rod 6, and a rotating shaft 8 is vertically fixed to the upper end of the pull rod 6. Support plates 9 are rotatably connected to both ends of the rotating shaft 8, and the support plates 9 are fixed to the bottom of the cabin 4. The power generation component includes a horizontal plate 10 vertically fixed to the pull rod 6. A rotating body 11 is rotatably connected to both ends of the horizontal plate 10. A pull rope 12 is fixed to the rotating body 11, and the end of the pull rope 12 extends upward into the cabin 4. Two generators 13 are centrally symmetrically arranged inside the cabin 4. The output ends of the two generators 13 are fixed to guide wheels 14, and the pull rope 12 is attached to the radially opened groove on the outer ring of the guide wheel 14. In this embodiment, the buoy communication device is equipped with a power-generating photovoltaic panel 37 on the top cover 3. The power-generating photovoltaic panel 37 is fixed at an angle to prevent sea birds from landing and covering it, or to prevent excrement from covering the power-generating photovoltaic panel 37. An energy storage power source can be installed in the cabin 4 to store the electrical energy produced by the power-generating photovoltaic panel 37 and the power generation components, while providing stable power to the communication body 2. Multiple rings of floats 38 are set on the outer ring of the hull 4 to float the entire buoy communication device on the sea surface; an anchor cable is set at the lower end of the counterweight 5 to stabilize the entire buoy communication device at the deployment location. The power generation component designed in this embodiment generates electricity based on sea surface fluctuations, as detailed below: The counterweight 5 is anchored and fixed to the seabed, so the swing range of the counterweight 5 below the sea surface is limited. The cabin 4 is rotatably connected to the tie rod 6 through the support plate 9. The cabin 4 can swing with the sea surface. During the swing, the cabin 4 tilts and the end of the pull rope 12 is pulled and fixed by the cross plate 10. At this time, the pull rope 12 will simultaneously rub the two guide wheels 14 to rotate. Each guide wheel 14 will drive the shaft 8 of the No. 1 generator 13 connected to it to rotate. At this time, both No. 1 generators 13 will generate electrical energy and store it in the energy storage power supply. The power generation component is installed on the buoy communication device and works in conjunction with the photovoltaic power generation panel. The two complement each other and can provide sufficient power in any environment, including harsh marine environments. The power generation component has a simple structure and can operate continuously and stably for a long time in harsh marine environments. In this embodiment, the power generation component generates power by swinging the cabin 4. The cabin 4, together with the top cover 3 and some components installed on it, has sufficient mass and large inertia. During the swinging process, it can continuously and stably pull the pull rope 12, that is, the pull rope 12 and the guide wheel 14 generate relative movement, effectively rubbing the guide wheel 14 to rotate and effectively generating power, providing sufficient power for the communication body 2, thereby ensuring that the communication body 2 can operate continuously and stably.

[0022] Reference Figure 1 - Figure 8 The cabin 4 is provided with a frame 15. The two ends of the frame 15 are fixed to the inner side wall of the cabin 4. Vertical plates 16 are fixed to the lower surfaces of both sides of the frame 15. The two vertical plates 16 are arranged symmetrically in the center. A rack 17 is slidably connected to the side wall of each vertical plate 16. A driven tooth 18 is engaged on one side of each rack 17. A second generator 19 is fixed to the driven tooth 18. The upper end of each rack 17 is connected to the frame 15 by a spring 20, and the lower end of each rack 17 is vertically fixed to a pressure plate 21. Each pressure plate 21 is provided with a pressure rod 22, which is bent at an acute angle. The end of the pressure rod 22 passes through the bottom of the cabin 4 and is fixed to the rotating shaft 8. A window is provided at the bottom of the cabin 4 for the pressure rod 22 to pass through. Sea surface fluctuations cause the cabin 4 to sway around the pivot 8, resulting in relative deflection of the cabin 4 and the pressure rod 22. Figure 5As shown, when the cabin 4 tilts to the left, the pressure plate 21 on the right side inside the cabin 4 will tend to move upward. At the same time, under the restriction of the pressure rod 22 on the right side, the pressure rod 22 on the right side will exert a downward squeezing force on the pressure plate 21 on the right side. Meanwhile, the pressure plate 21 on the right side will drive the first rack 17 on the right side to slide on the vertical plate 16. The first rack 17 on the right side will rub the driven tooth 18 on the right side to rotate. The driven tooth 18 on the right side is fixed to the output shaft of the second generator 19 on the right side inside the cabin 4. The output shaft of the second generator 19 rotates and generates electrical energy stored in the energy storage power supply. Similarly, when the cabin 4 tilts to the right, the first rack 17 on the left side rotates the driven gear 18 on the left side, and the driven gear 18 on the left side is fixed to the output shaft of the second generator 19 on the left side. The output shaft of the second generator 19 on the left side rotates and generates electrical energy stored in the energy storage power source. When the pressure rod 22 does not press against the pressure plate 21, that is, when the buoy body 1 is in a stable state, the first rack 17 moves upward and resets under the tension of the spring 20 connected to it, ready for the next rotation to generate electricity.

[0023] Reference Figure 1 - Figure 8 Each of the first rack 17 is fixed to one side of a second rack 23. The teeth of the second rack 23 are oriented opposite to those of the first rack 17. A gear assembly for transmitting power is provided between the second rack 23 and the guide wheel 14. The gear assembly includes a pulley 24, a first gear 25, and a second gear 26 disposed on the end face of the guide wheel 14; the end of the first gear 25 is coaxially provided with the pulley 24, the pulley 24 on the first gear 25 is connected to the pulley 24 on the end face of the guide wheel 14 by a belt, the first gear 25 meshes with the second gear 26, the second gear 26 meshes with the second rack 23, and the first gear 25 and the second gear 26 are each connected to the inner wall of the cabin 4 by a shaft; When the cabin 4 tilts to the left, the left gear assembly and the left guide wheel 14 rotate clockwise. The guide wheel 14 drives the pulley 24 on it to rotate in the same direction. At the same time, the belt drives the first gear 25 to rotate in the same direction. The first gear 25 meshes with the second gear 26. The second gear 26 rotates in the opposite direction to the first gear 25. At this time, the second gear 26 rotates counterclockwise and rubs the second rack 23, so that the second rack 23 and the first rack 17 move synchronously towards the frame 15. The auxiliary spring 20 makes the left first rack 17 quickly move upward and reset, preparing for the cabin 4 to tilt to the right. The gear assembly on the right side has a guide wheel 14 that rotates clockwise. The guide wheel 14 drives the pulley 24 on it to rotate in the same direction. At the same time, the pulley drives the first gear 25 to rotate in the same direction via the belt. The first gear 25 meshes with the second gear 26. The second gear 26 rotates in the opposite direction to the first gear 25. At this time, the second gear 26 rotates counterclockwise and rubs the second rack 23, so that the second rack 23 and the first rack 17 move synchronously away from the frame 15. The auxiliary pressure rod 22 squeezes the pressure plate 21, increases the downward movement of the first rack 17, increases the rotation angle of the driven wheel, and thus increases the power generation of the second generator 19. Similarly, when the cabin 4 tilts to the right, the right gear assembly and the right guide wheel 14 rotate counterclockwise. The guide wheel 14 drives the pulley 24 on it to rotate in the same direction. At the same time, the belt drives the first gear 25 to rotate in the same direction. The first gear 25 meshes with the second gear 26. The second gear 26 rotates in the opposite direction to the first gear 25. At this time, the second gear 26 rotates clockwise and rubs the second rack 23, so that the second rack 23 and the first rack 17 move synchronously towards the frame 15. The auxiliary spring 20 makes the first rack 17 on the right side move up and reset quickly, preparing for the cabin 4 to tilt to the left. The left-side gear assembly has a guide wheel 14 that rotates counterclockwise. The guide wheel 14 drives the pulley 24 on it to rotate in the same direction, and at the same time drives the first gear 25 to rotate in the same direction via the belt. The first gear 25 meshes with the second gear 26. The second gear 26 rotates in the opposite direction to the first gear 25. At this time, the second gear 26 rotates clockwise and rubs the second rack 23, so that the second rack 23 and the first rack 17 move synchronously away from the frame 15. The auxiliary pressure rod 22 squeezes the pressure plate 21, increases the downward movement of the first rack 17, increases the rotation angle of the driven wheel, and thus increases the power generation of the second generator 19.

[0024] Reference Figure 1 - Figure 8 The frame 15 has sliding holes in the middle of both side plates, and the pull rope 12 passes through the sliding holes. The pull rope 12 is fixed to the limiting plate 27 at the part between the two sliding holes. The limiting plate 27 has compression springs 28 on both sides. The cabin 4 sways with the fluctuations of the seawater. If the swaying amplitude of the cabin 4 is too large, the seawater will soak into the communication body 2, which may cause a short circuit in the communication body 2. To address this, a compression spring 28 is installed to limit the swaying of the cabin 4. During the swaying process of the cabin 4, the compression spring 28 will press against the frame 15, constraining the distance between the upper limit plate 27 of the pull rope 12 and the guide wheel 14, thereby constraining the swaying amplitude of the cabin 4 and thus protecting the communication body 2 on the top cover 3.

[0025] Reference Figure 1 - Figure 8A limiting cylinder 29 is fixedly connected to the middle position of the outer surface of the two side plates of the frame 15. The axis of the limiting cylinder 29 is set in the same line as the axis of the sliding hole, and the pull rope 12 passes through the sliding hole and the limiting cylinder 29. Each of the compression springs 28 is cone-shaped, with the tip of the compression spring 28 facing the inside of the limiting cylinder 29; The compression spring 28 and the limiting cylinder 29 work together so that the end of the compression spring 28 is embedded in the limiting cylinder 29, which limits the radial deflection of the compression spring 28 and reduces the squeezing wear on the pull rope 12. At the same time, the conical shape of the compression spring 28 ensures that the compression spring 28 can be accurately embedded in the limiting cylinder 29 each time, so as to prevent the end of the compression spring 28 from hitting the edge of the opening of the limiting cylinder 29, causing the compression spring 28 to deflect radially and causing squeezing wear on the pull rope 12. After all, the frequent fluctuations of the sea surface will also cause the cabin 4 to swing frequently, which is a wear condition of the pull rope 12 that needs to be considered.

[0026] Reference Figure 1 - Figure 8 A through hole 30 is provided on the cabin 4 at the position through which the pull rope 12 passes. An anti-wear sleeve 31 is provided in the through hole 30. The outer ring of the anti-wear sleeve 31 is radially rotatably connected to the inner side wall of the through hole 30. The pull rope 12 passes through the anti-wear sleeve 31. The anti-wear sleeve 31 is also used to protect the pull rope 12 to prevent wear between the pull rope 12 and the cabin 4. The anti-wear sleeve 31 can be made of some soft rubber material. At the same time, the two ends of the anti-wear sleeve 31 are flared to further improve the protection effect on the pull rope 12.

[0027] Reference Figure 1 - Figure 8 The end of the pressure rod 22 that is pressed against the pressure plate 21 is rotatably connected to a roller 32, which rolls against the upper surface of the pressure plate 21. A roller 32 is provided at the contact point between the pressure rod 22 and the pressure plate 21. The roller 32 is rotatably connected to the pressure rod 22. When the pressure rod 22 applies pressure to the pressure plate 21, the sliding friction between the pressure rod 22 and the pressure plate 21 can be converted into rolling friction between the roller 32 and the pressure plate 21, thereby reducing the relative movement resistance between the pressure rod 22 and the pressure plate 21 and improving the smoothness of the pressure plate 21 driving the first rack 17 to move.

[0028] Reference Figure 1 - Figure 8 The pull rod 6 includes multiple sleeves 33, with adjacent sleeves 33 being threaded together, and the sleeves 33 being filled with energy storage power. The pull rod 6 is set as a hollow sleeve 33, which can be used to load energy storage power, reduce the space occupied by the energy storage power in the cabin, and free up more space to install the communication body 2 and its supporting facilities.

[0029] Reference Figure 1- Figure 8 The counterweight 5 includes a support plate 34 and multiple counterweight plates 35 stacked on the support plate 34. The center of the support plate 34 is fixed to the lower end of the bottom sleeve 33, and each counterweight plate 35 is sleeved on the outer ring of the bottom sleeve 33 at the middle position. This buoy communication device can be used not only at sea, but also in some rivers or lakes to monitor water quality and other data. Depending on the specific environment in which the buoy communication device is used, different numbers of counterweight plates 35 can be set for flexible weight adjustment.

[0030] Reference Figure 1 - Figure 9 The cabin 4 is provided with an annular hollow cover 36 below. The upper end of the hollow cover 36 is set in a wide-mouth shape. The inner sidewall of the hollow cover 36 is fixed to both ends of the horizontal plate 10. The lower end of the hollow cover 36 is set in a narrow diameter and extends towards the counterweight 5. A perforated cover 36 is provided to cover the connection between the counterweight 5 and the cabin 4. This can block foreign objects such as fishing nets or ropes from getting tangled. The lower end of the perforated cover 36 is narrowed to prevent fish from crawling between the perforated cover 36 and the counterweight and blocking the rotational connection between the cabin 4 and the counterweight 5.

[0031] Working principle: The power generation component designed in this embodiment generates electricity based on sea surface fluctuations, as detailed below: The counterweight 5 is anchored and fixed to the seabed, so the swing range of the counterweight 5 below the sea surface is limited. The cabin 4 is rotatably connected to the tie rod 6 through the support plate 9. The cabin 4 can swing with the sea surface. During the swing, the cabin 4 tilts and the end of the pull rope 12 is pulled and fixed by the cross plate 10. At this time, the pull rope 12 will simultaneously rub the two guide wheels 14 to rotate. Each guide wheel 14 will drive the shaft 8 of the No. 1 generator 13 connected to it to rotate. At this time, both No. 1 generators 13 will generate electrical energy and store it in the energy storage power supply. At the same time, when the cabin 4 tilts to the left, the pressure plate 21 on the right side inside the cabin 4 will tend to move upward. Meanwhile, under the restriction of the pressure rod 22 on the right side, the pressure rod 22 on the right side will exert a downward squeezing force on the pressure plate 21 on the right side. At the same time, the pressure plate 21 on the right side will drive the first rack 17 on the right side to slide on the vertical plate 16. The first rack 17 on the right side will rub the driven tooth 18 on the right side to rotate. The driven tooth 18 on the right side is fixed to the output shaft of the second generator 19 on the right side inside the cabin 4. The output shaft of the second generator 19 rotates and generates electrical energy stored in the energy storage power supply. Similarly, when the cabin 4 tilts to the right, the first rack 17 on the left side rotates the driven gear 18 on the left side, and the driven gear 18 on the left side is fixed to the output shaft of the second generator 19 on the left side. The output shaft of the second generator 19 on the left side rotates and generates electrical energy stored in the energy storage power source. When the pressure rod 22 does not press against the pressure plate 21, that is, when the buoy body 1 is in a stable state, the first rack 17 moves upward and resets under the tension of the spring 20 connected to it, ready for the next rotation to generate electricity.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
