Description

Technical Field

[0001] This utility model relates to the technical field of laser wind measurement radar devices, and more specifically, to a floating laser wind measurement radar device at sea. Background Technology

[0002] Coherent Doppler wind lidar is a device system that uses laser remote sensing to measure atmospheric wind fields. It is currently widely used in wind farm preliminary measurements, meteorology, and environmental protection. Compared to traditional wind measurement towers, using wind cups and wind vanes offers advantages such as smaller size, less construction work, longer measurement distance, better measurement accuracy and consistency, and resistance to freezing rain and extreme weather conditions like gales.

[0003] In marine applications, these advantages are even more pronounced. However, the cost of building wind measurement towers at sea is extremely high and highly dependent on water depth and seabed geology. Currently, floating wind measurement lidar systems mounted on large buoy systems have emerged. These systems utilize the large buoy system's solar-powered self-powered system and employ a combined positioning and navigation system to calculate the lidar's heading and attitude data in real time, correcting beam pointing deviations in real time, and outputting real-time wind measurement data through correction algorithms. However, these systems have high power consumption and require relatively large buoy platforms due to their solar power supply. This results in still high costs, and the production, deployment, retrieval, and maintenance of large buoys are also expensive and time-consuming, making mass production and commercial operation difficult, and thus remaining in the stage of customized development.

[0004] While existing floating laser wind radar devices rely on solar power, during long rainy seasons, the amount of solar energy converted into electricity decreases as the sunshine duration shortens, leading to insufficient power supply. Since seawater is constantly flowing due to tidal movements, this paper proposes a floating laser wind radar device that can utilize tidal energy to convert into electrical energy for power replenishment, thereby ensuring a stable power supply. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a floating laser wind radar device for the sea, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a floating laser wind radar device for sea use, comprising a floating platform body, a rotating column at the bottom of the floating platform body, a fixed frame installed inside the rotating column, a power generation mechanism connected to the fixed frame, a connecting member installed between the rotating column and the floating platform body, a current meter installed on the connecting member, a toothed ring installed at the top of the rotating column, and a reversing mechanism provided inside the floating platform body, the bottom end of the reversing mechanism being engaged with the toothed ring.

[0007] Preferably, the bottom end of the toothed ring is provided with an annular groove, a ball bearing is installed in the annular groove, an annular track is installed inside the connector, the annular track is inserted into the annular groove, and each ball bearing is pressed onto the annular track.

[0008] Preferably, the power generation mechanism includes a small generator, a drive shaft, a first gear, a rotating rod, a second gear, and a turbine. The small generator is installed in the floating platform body. The input end of the small generator is connected to the drive shaft. The first gear is installed at the bottom end of the drive shaft. The rotating rod is rotatably mounted on a fixed frame. The second gear is installed at one end of the rotating rod, and the turbine is installed at the other end of the rotating rod.

[0009] Preferably, both the first gear and the second gear are bevel gears, and the first gear and the second gear are meshed together.

[0010] Preferably, the rotating column has a water passage hole, one end of which has a water inlet and the other end has a water outlet. Both the water inlet and the water outlet are funnel-shaped, and the inner diameter of the water passage hole is smaller than the minimum inner diameter of the water inlet.

[0011] Preferably, the reversing mechanism includes a motor, a drive shaft, and a drive gear. The motor is installed inside the floating platform body, the output end of the motor is connected to the drive shaft, and the bottom end of the drive shaft is equipped with a drive gear, which meshes with a gear ring.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. By impacting the turbine with seawater, the turbine drives the rotating rod to rotate, which in turn causes the second gear to mesh with the first gear and rotate. This, in turn, drives the output end of a small generator to rotate, thereby generating electricity. This technology can utilize the power generated by the tidal flow of seawater to convert it into electrical energy, thereby increasing power generation and ensuring the stable operation of the laser wind radar device in different weather conditions.

[0014] 2. As seawater enters through the inlet, the inner diameter of the water passage gradually decreases. According to Laval's principle, this increases the flow velocity of the seawater as it enters the water passage, thereby increasing the impact speed of the seawater on the turbine and thus increasing the turbine's rotational speed. This, in turn, improves power generation efficiency and output.

[0015] 3. The motor drives the drive shaft to rotate, which in turn drives the drive gear to rotate the gear ring, causing the rotating column to rotate. This allows the direction of the water inlet to be adjusted, so that the flow direction of the seawater can be detected by the current meter. By adjusting the direction of the water inlet to match the direction of the seawater, the flow speed of the seawater entering the water inlet can be further increased, thereby improving the power generation efficiency.

[0021] 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.

[0022] As attached Figure 1-4The floating laser wind radar device shown includes a floating platform body 1, a rotating column 2 at the bottom of the floating platform body 1, a fixed frame 7 installed inside the rotating column 2, a power generation mechanism 4 connected to the fixed frame 7, a connector 3 installed between the rotating column 2 and the floating platform body 1, a current meter 5 installed on the connector 3, a toothed ring 8 installed at the top of the rotating column 2, a reversing mechanism 9 installed inside the floating platform body 1, the bottom end of the reversing mechanism 9 engaging with the toothed ring 8, an annular groove opened at the bottom end of the toothed ring 8, ball bearings installed in the annular groove, an annular track 6 installed inside the connector 3, the annular track 6 being inserted into the annular groove, and each ball bearing pressing against the annular track 6.

[0023] In practical implementation, the current meter 5 detects the direction of seawater flow and, in conjunction with the direction-changing mechanism 9, causes the rotating column 2 to rotate. This aligns the bottom of the power generation mechanism 4 with the direction of seawater flow, allowing the seawater to impact the bottom of the power generation mechanism 4 and convert the kinetic energy of the seawater into electrical energy. This ensures a stable power supply for the device, making it usable in various weather conditions. Furthermore, during the rotation of the rotating column 2, the annular track 6, in conjunction with the annular groove, allows the balls to roll, reducing rotational friction and making the rotation smoother. This also reduces power consumption and wear on the connecting structures.

[0024] The power generation mechanism 4 includes a small generator 401, a drive shaft 402, a first gear 403, a rotating rod 404, a second gear 405, and a turbine 406. The small generator 401 is installed inside the floating platform body 1. The input end of the small generator 401 is connected to the drive shaft 402. The first gear 403 is installed at the bottom end of the drive shaft 402. The rotating rod 404 is rotatably mounted on the fixed frame 7. The second gear 405 is installed at one end of the rotating rod 404, and the turbine 406 is installed at the other end of the rotating rod 404. The first gear 403 and the second gear 405 are both bevel gears, and the first gear 403 and the second gear 405 are meshed together.

[0025] In practice, the turbine 406 is impacted by seawater, causing the turbine 406 to drive the rotating rod 404 to rotate. This causes the second gear 405 to mesh with the first gear 403 and rotate, which in turn causes the transmission shaft 402 to drive the output end of the small generator 401 to rotate, thereby generating electricity. This device can utilize the power generated by the tidal flow of seawater to convert it into electrical energy, thereby increasing the power generation and ensuring the stable operation of the laser wind radar device in different weather conditions.

[0026] The rotating column 2 has a water passage hole, with an inlet at one end and an outlet at the other end. Both the inlet and outlet are funnel-shaped, and the inner diameter of the water passage hole is smaller than the minimum inner diameter of the inlet.

[0027] In practice, as seawater enters through the inlet, the inner diameter of the water passage gradually decreases. According to Laval's principle, this increases the flow velocity of the seawater as it enters the water passage, thereby increasing the impact speed of the seawater on the turbine 406 and thus increasing the rotational speed of the turbine 406. This, in turn, improves power generation efficiency and output.

[0028] The reversing mechanism 9 includes a motor, a drive shaft, and a drive gear. The motor is installed inside the floating platform body 1. The output end of the motor is connected to the drive shaft. The bottom end of the drive shaft is equipped with a drive gear, which meshes with the gear ring 8.

[0029] In practice, the motor drives the drive shaft to rotate, which in turn drives the drive gear to rotate the gear ring 8, causing the rotating column 2 to rotate. This allows the direction of the water inlet to be adjusted, so that the current meter 5 can detect the flow direction of the seawater and adjust the direction of the water inlet to match the direction of the seawater. This can further increase the flow speed of the seawater entering the water inlet, thereby improving the power generation efficiency.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
