Technical Field
[0001] The present invention relates to the technical field of wind power generation, and in particular to a wind measuring device for wind power generation. Background Art
[0002] In the field of wind power generation, accurate measurement of wind resource parameters such as wind speed and direction is crucial for wind turbine design, site selection, and operational optimization. The accuracy of wind resource data directly impacts wind farm planning, turbine selection, and subsequent power generation efficiency, and is fundamental to the entire wind power industry. Existing wind measurement devices have several shortcomings in practical applications. Therefore, a wind measurement device for wind power generation is needed.
[0003] The wind measurement direction adjustment range of existing devices is limited and cannot fully cover the wind direction changes in complex wind fields; existing devices are prone to sensor freezing in low temperature environments, resulting in distorted measurement data. Summary of the Invention
[0004] The purpose of the present invention is to solve the problems of inflexible wind direction adjustment and poor adaptability to low temperature environments of existing devices, and to propose a wind measuring device for wind power generation.
[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a wind measuring device for wind power generation, comprising a spiral seat, a column, a rotating slot and an adjustment component, the top of the spiral seat is fixedly connected to the column, the top of the column is provided with a rotating slot, the inner wall of the rotating slot is rotatably connected to the adjusting component, the adjusting component includes a sphere rotatably connected to the inner wall of the rotating slot, the inner wall of the rotating slot is provided with a slot, the inner wall of the slot is inserted into and rotatably connected to a rotating rod, the surface of the rotating rod is fixedly connected to the sphere, and one end of the rotating rod is fixedly connected to a motor.
[0006] Furthermore, the other end of the rotating rod is fixedly connected to a limiting block, and the surface of the limiting block abuts against the surface of the column.
[0007] Furthermore, a detection seat is fixedly connected to the top of the sphere, and a level is fixedly connected to the surface of the detection seat.
[0008] Furthermore, a fixing column is fixedly connected to the top of the detection seat, and two rings are fixed on the surface of the fixing column.
[0009] Furthermore, the surface of the ring is rotatably and clampedly connected to a rotating drum, and the surface of the rotating drum is fixedly connected to four connecting rods.
[0010] Furthermore, one end of the connecting rod is fixedly connected to a wind meter, and the interior of the wind meter is fixedly connected to an antifreeze component.
[0011] Furthermore, the antifreeze component includes a heating arc tube fixedly connected to the inside of the anemometer, the inside of the heating arc tube is fixedly connected to a heating wire, the surface of the anemometer is made of pit impact antifreeze material, and the inner wall of the anemometer is fixedly connected to a temperature sensor.
[0012] Compared with the prior art, the advantages and positive effects of the present invention are:
[0013] 1. In the present invention, by providing an adjustment component, a motor drives the rotating rod to rotate in the slot, driving the sphere to achieve 180° pitch adjustment in the rotating groove, so that the detection seat can be aligned with the incoming wind direction in real time, reducing the error of wind direction tracking. The abutment structure between the limit block and the surface of the column limits the axial displacement of the rotating rod, and the precise fit between the rotating groove and the sphere ensures a smooth and shake-free adjustment process. The spirit level monitors the horizontal state of the detection seat in real time, and the motor automatically starts to perform leveling to ensure the measurement reference accuracy of the anemometer. This component enables the wind measuring device to adapt to sudden changes in wind direction in complex terrain such as valleys and hills. Compared with traditional devices, it can expand the coverage of wind direction and improve the efficiency of measurement data.
[0014] 2. In the present invention, by setting an antifreeze component, the heating arc tube can quickly heat up to 5°C in an environment of -30°C. The temperature sensor monitors and controls the power of the heating wire in real time to maintain the internal temperature of the anemometer above 0°C. The shell of the impact-resistant antifreeze material has both low-temperature resistance and hail impact resistance. It does not crack in the temperature cycle of -40°C to 70°C and can withstand the impact of hail. When the ambient temperature is lower than -5°C, the antifreeze component automatically starts. This component solves the problem of freezing and failure of wind measuring devices in extremely cold areas, enables wind measurement data to be effectively collected in winter, and provides reliable data support for wind resource assessment in high-latitude areas.

[0023] The specific settings and functions of the regulating component 4 and the antifreeze component 10 are described in detail below.
[0024] In this embodiment: the adjustment component 4 includes a sphere 41 rotatably connected to the inner wall of the rotating groove 3, a slot 42 is opened on the inner wall of the rotating groove 3, a rotating rod 43 is inserted into the inner wall of the slot 42 and rotatably connected, the surface of the rotating rod 43 is fixedly connected to the sphere 41, and one end of the rotating rod 43 is fixedly connected to the motor 44.
[0025] The effect achieved by the above components is: by setting up a motor 44 to drive the rotating rod 43 to rotate in the slot 42, the ball 41 is driven to achieve 180° pitch adjustment in the rotating groove 3. The cooperation between the ball 41 and the rotating groove 3 ensures that the detection seat 46 is aligned with the incoming wind direction in real time.
[0026] Specifically, the other end of the rotating rod 43 is fixedly connected to the limiting block 45 , and the surface of the limiting block 45 abuts against the surface of the column 2 .
[0027] The effects achieved by the above components are: by setting the limit block 45 to limit the axial displacement of the rotating rod 43, the ball 41 is prevented from escaping from the rotating groove 3, and at the same time, an abutment structure is formed with the surface of the column 2, thereby enhancing the stability of the rotating rod 43 during rotation and reducing the amount of shaking.
[0028] Specifically, a detection seat 46 is fixedly connected to the top of the sphere 41 , and a level 47 is fixedly connected to the surface of the detection seat 46 .
[0029] The effects achieved by the above components are: by setting up the detection base 46 to carry the wind measuring instrument, the spirit level 47 monitors the horizontal state of the detection base 46 in real time. When an unexpected tilt occurs, a signal is sent to the motor 44 for automatic leveling, thereby ensuring the measurement reference accuracy of the wind meter 9 and reducing the error of the horizontal adjustment.
[0030] Specifically, a fixing column 5 is fixedly connected to the top of the detection seat 46 , and two rings 6 are fixed to the surface of the fixing column 5 .
[0031] The effects achieved by the above components are: by setting the fixing column 5 to provide installation support for the ring 6, the two rings 6 are distributed parallel to each other, providing a rotation track for the rotating drum 7, and reducing the coaxiality deviation of the rotating drum 7 when rotating.
[0032] Specifically, the surface of the ring 6 is rotatably and clampedly connected to the rotating drum 7 , and the surface of the rotating drum 7 is fixedly connected to four connecting rods 8 .
[0033] The above components achieve the following effects: by setting the rotating drum 7 and the ring 6 to rotate freely under the action of wind, the four connecting rods 8 are evenly distributed at 90 degrees, driving the anemometer 9 to rotate synchronously, realizing 360-degree wind direction measurement.
[0034] Specifically, one end of the connecting rod 8 is fixedly connected to the anemometer 9 , and the interior of the anemometer 9 is fixedly connected to the antifreeze assembly 10 .
[0035] The effects achieved by the above components are: by setting the connecting rod 8, the anemometer 9 is fixed to the drum 7, so that the anemometer 9 rotates with the drum 7 and is aligned with the wind direction in real time. The antifreeze component 10 ensures that the anemometer 9 works normally in a low temperature environment, ensuring the accuracy of the measurement data.
[0036] Specifically, the antifreeze component 10 includes a heating arc tube 101 fixedly connected to the inside of the anemometer 9, the inside of the heating arc tube 101 is fixedly connected to a heating wire, the surface of the anemometer 9 is made of pit impact antifreeze material, and the inner wall of the anemometer 9 is fixedly connected to a temperature sensor.
[0037] The effects achieved by the above components are: by setting the heating arc tube 101, it automatically starts when the temperature sensor detects that the internal temperature is lower than 0°C, and the internal temperature of the anemometer 9 is raised to 5°C in a short time. The shell of the impact-resistant and antifreeze material can withstand temperature changes of -50°C to 80°C and hail impacts, ensuring the reliability of wind measurement data in low temperature environments.
[0038] Working principle: By setting the adjustment component 4, the motor 44 drives the rotating rod 43 to rotate in the slot 42, driving the ball 41 to achieve 180° pitch adjustment in the rotating groove 3, so that the detection seat 46 can be aligned with the incoming wind direction in real time, reducing the error of wind direction tracking. The abutment structure of the limit block 45 and the surface of the column 2 limits the axial displacement of the rotating rod 43, and the precise fit between the rotating groove 3 and the ball 41 ensures that the adjustment process is smooth and without shaking. The spirit level 47 monitors the horizontal state of the detection seat 46 in real time, and the motor 44 automatically starts to level it to ensure the measurement reference accuracy of the anemometer 9. This component enables the wind measuring device to adapt to the sudden change of wind direction in complex terrain such as valleys and hills. Compared with traditional devices, it can expand the coverage of wind direction and improve the efficiency of measurement data.
[0039] By setting up the antifreeze component 10, the heating arc tube 101 can quickly heat up to 5°C in an environment of -30°C. The temperature sensor monitors and controls the power of the heating wire in real time to maintain the internal temperature of the anemometer 9 above 0°C. The shell of the impact-resistant antifreeze material has both low-temperature resistance and hail impact resistance. It does not crack in the temperature cycle of -40°C to 70°C and can withstand the impact of hail. When the ambient temperature is lower than -5°C, the antifreeze component 10 automatically starts. This component solves the problem of freezing and failure of wind measuring devices in extremely cold areas, enables wind measurement data to be effectively collected in winter, and provides reliable data support for wind resource assessment in high-latitude areas.
