For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] Example 1: Figure 1-6 As shown, an observation platform for offshore positioning and real-time water level transmission includes a floating plate 100, a power generation device installed outside or inside the floating plate 100, an antenna 600, a transmission terminal, a tide gauge 800, and a water level gauge. The power generation device includes a solar panel 400 and a wind turbine 500. The upper side of the floating plate 100 is rotatably connected to a rotating seat assembly 300. In this example, a solar panel 400 and a wind turbine 500 are fixed to the top array of the rotating seat assembly 300. The antenna 600 is fixedly installed at the top center of the floating plate 100. Among them, the transmission terminal is preferably a Beidou short message data transmission terminal 700, and the water level gauge preferably uses a self-contained water level gauge 900. The Beidou short message data transmission terminal 700 and the tide gauge 800 are installed inside the floating plate 100, and the self-contained water level gauge 900 is installed at the bottom of the floating plate 100. The self-contained water level gauge 900 is connected to the tide alarm 800 through a cable, and the tide alarm 800 is connected to the Beidou short message data transmission terminal 700. The Beidou short message data transmission terminal 700 integrates a short message communication module and a GPS / BD dual-mode positioning module. While providing Beidou short message communication function, it can also provide high-precision positioning. With data transparent transmission as the core, it also supports simple command mode. With simple settings, remote and wireless network communication can be easily realized. Beidou short message data transmission terminal 700 is used to transmit tide data.

[0032] like Figure 2-6As shown, the floating plate 100 includes a disc-shaped seat 101 and a sealing cover 102, and the disc-shaped seat 101 and the sealing cover 102 enclose a circular cavity to ensure the buoyancy of the floating plate 100. A boss 103 is fixedly connected to the top center position of the sealing cover 102, and the cross-section of the boss 103 is T-shaped. The antenna 600 is fixedly installed on the boss 103 of the floating plate 100, and an annular notch 104 is opened through the top surface of the sealing cover 102.

[0033] A buoyancy assembly is arranged outside the floating plate 100, and the buoyancy assembly is located at the side or bottom of the floating plate 100. The buoyancy assembly includes an annular buoy 105 arranged circumferentially outside the floating plate 100, and / or a linear buoy 106 and a leg 107 arranged at the bottom of the floating plate 100. Specifically, an annular buoy 105 is fixedly installed on the circumferential surface of the disc-shaped seat 101 and the sealing cover 102 to enhance the anti-collision strength and buoyancy. A linear buoy 106 and a leg 107 are fixedly arranged at the bottom of the disc-shaped seat 101. The buoyancy of the floating plate 100 is enhanced by the arrangement of the linear buoy 106, and the stability of the floating plate 100 is enhanced by the arrangement of the leg 107. At the same time, in this example, a steel cable 108 is fixedly installed at the bottom center of the disc-shaped seat 101, and a counterweight block 109 is fixedly installed at the bottom end of the steel cable 108. The counterweight block 109 cooperates with the steel cable 108 to apply a downward pulling force to the disc-shaped seat 101 and the sealing cover 102 to prevent the floating plate 100 from drifting away under the action of waves.

[0034] like Figure 2 , 5 As shown, the rotating seat assembly 300 includes a rotating ring 301 rotatably connected to the inside of the disc-shaped seat 101, a ring gear 303 fixedly connected to the outer wall of the rotating ring 301, a driving gear 305 meshing with the ring gear 303, and a motor 304 connected to the driving gear 305, wherein the rotating ring 301 and the disc-shaped seat 101 can be rotatably connected through an annular guide rail, or can be rotatably connected through the support beam 200 preferably used in this application. The rotating ring 301 passes through the annular notch 104 and is fixedly connected with a rotating seat body 306, the rotating seat body 306 is located at the top of the sealing cover 102, and the power generation device is installed above the rotating seat body 306, and the driving gear 305 is connected to rotate through the motor 304, driving the ring gear 303 and the rotating ring 301 to rotate, thereby driving the rotating seat body 306 to rotate, and adjusting the direction of the solar panel 400 and the wind turbine 500.

[0035] A battery is also provided inside the floating plate 100, and the solar panel 400 and the wind turbine 500 are used to charge the battery, and the battery is used to power the motor 304. In this example, a wind direction sensor is also provided on the top of the boss 103 to receive wind direction information. The wind direction sensor signal is connected to a controller, and the controller is connected to the motor 304 signal. When the wind direction changes, the controller controls the motor 304 to start, and controls the number of revolutions of the output end of the motor 304. In addition, by positioning the floating plate 100, the weather and the angle of the sun in the area where the floating plate 100 is located are understood, and then the controller controls the motor 304 to start, and controls the number of revolutions of the output end of the motor 304. In addition, during the power generation process, the solar panel 400 generates electricity mainly, and the wind turbine 500 generates electricity as a supplement.

[0036] The rotating seat body 306 is sleeved outside the boss 103, and the upper surface of the rotating seat body 306 is inclined. In this example, the inclination angle of the top of the rotating seat body 306 from the edge to its center is preferably but not limited to five degrees, which facilitates the flow of seawater from the top of the rotating seat body 306 to the edge.

[0037] like Figure 2 , 5 As shown, the swivel 301 is rotatably connected to the disc-shaped seat 101 via a support beam 200, and the support beam 200 includes an annular hollow beam 201 fixedly installed between the disc-shaped seat 101 and the sealing cover 102, and a plurality of groups of straight hollow beams 202 circumferentially arranged outside the annular hollow beam 201, and the annular hollow beam 201 is located at the center of the disc-shaped seat 101 and the sealing cover 102. In this example, the annular hollow beam 201 and the straight hollow beam 202 are hollow and interconnected to ensure the buoyancy of the floating plate 100.

[0038] A mounting groove 204 is provided at the top of the straight hollow beam 202, and the rotating ring 301 is placed in the mounting groove 204 and can slide relative to the mounting groove 204. Specifically, in this example, a embedding groove 205 is provided on the inner wall of the straight hollow beam 202, and the embedding groove 205 is located on the inner wall of the mounting groove 204 near the center of the annular hollow beam 201. At the same time, an embedding ring 302 is fixedly installed in the rotating ring 301, and the cross section of the embedding ring 302 is in a "convex" shape. The embedding ring 302 is rotatably connected in the embedding groove 205, so that the rotating ring 301 is stably connected to the straight hollow beam 202.

[0039] A support platform 203 is fixedly installed at the center of the annular hollow beam 201, and the upper side of the support platform 203 is tightly fitted with the bottom surface of the sealing cover 102. The antenna 600 is fixedly installed at the center of the top of the sealing cover 102, so that the support strength of the antenna 600 is enhanced by the support platform 203. In addition, an array of inclined anchor rods 601 is arranged on the antenna 600, and the other end of the inclined anchor rods 601 is fixed to the top of the boss 103 to ensure the stability of the antenna 600.

[0040] In addition, batteries are also used to power Beidou short message data transmission terminals, tide gauges and self-contained water level gauges. When designing the height of the antenna, the height of the antenna is inversely proportional to the stability of the antenna and directly proportional to the transmission distance. Under fixed frequency conditions, factors that affect the communication distance include: transmitting frequency, receiving sensitivity, propagation loss, antenna gain, etc. The surrounding environment's absorption of radio waves, multipath interference, propagation loss, etc. cannot be changed. The transmitting frequency, receiving sensitivity and antenna height can be optimized; in actual signal propagation, strong signals can be received at places beyond the limit distance. This phenomenon is called beyond-horizon transmission. The reason for this phenomenon is atmospheric refraction. The beyond-horizon propagation distance can be expressed by the following formula:

[0041]

[0042] Where D is the beyond-horizon propagation distance; ht is the height of the receiving antenna; hr is the height of the transmitting antenna; and the unit is meter.

[0043] Embodiment 2: The present application also discloses an observation method for offshore positioning and real-time water level transmission, based on the above-mentioned observation platform for offshore positioning and real-time water level transmission, comprising the following steps:

[0044] S1. Maritime positioning: The Beidou short message data transmission terminal 700 integrates a short message communication module and a GPS / BD dual-mode positioning module for maritime positioning;

[0045] S2. Water level detection, monitoring the water level through the self-contained water level gauge 900, the self-contained water level gauge 900 is connected to the tide meter 800 through a cable, and the tide meter 800 is connected to the Beidou short message data transmission terminal 700 signal, thereby transmitting the water level data to the Beidou short message data transmission terminal 700;

[0046] S3. Data transmission: The Beidou short message data transmission terminal 700 cooperates with the antenna 600 to receive and transmit signals, thereby transmitting positioning data; the water level data is transmitted through the Beidou short message data transmission terminal 700 and the antenna 600.

[0047] The present invention drives the gear to rotate through a motor connection, thereby driving the swivel and the swivel seat body to rotate, thereby driving the orientation of the solar panel and the wind turbine to change to adapt to changes in wind direction and solar radiation angle, thereby achieving the purpose of ensuring power generation efficiency; at the same time, the present invention designs the height of the antenna through the beyond-horizon propagation distance expression formula, thereby ensuring the propagation distance of data transmission, and has a high application and promotion value.

[0048] The above is only a preferred embodiment of the present invention.
