Technical Field

[0001] This utility model belongs to the field of wind speed sensor technology, specifically relating to an adaptive wind speed sensor for wind power generation. Background Technology

[0002] An anemometer is a device used to measure wind speed. It is small, lightweight, and easy to carry and assemble. Based on its working principle, it can be roughly divided into mechanical anemometers and ultrasonic anemometers. It effectively obtains wind speed information. The housing is made of high-quality aluminum alloy profiles or polycarbonate composite materials, making it rainproof, corrosion-resistant, and anti-aging. It is a convenient, safe, and reliable intelligent instrument. It is mainly used in meteorology, agriculture, shipbuilding, wind power generation, and other fields, and can be used outdoors for extended periods.

[0003] Existing adaptive wind speed sensors, through the combined use of a heating component, a first protective component, and a second protective component, can effectively ensure the normal rotation of the wind cups and increase the stability of the adaptive wind speed sensor. However, they cannot change the orientation of the wind cups, affecting the judgment of wind speed and narrowing the scope of application. Furthermore, during use, the distance between the wind cups cannot be arbitrarily extended, and the position of the wind cups cannot be adjusted according to the site environment. Utility Model Content

[0004] To address the problems mentioned in the background section, this invention provides an adaptive wind speed sensor for wind power generation, which features the ability to adjust the orientation of the wind cups and increase the measurement radius based on the environment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adaptive wind speed sensor for wind power generation, including a fixed base, a steering mechanism at the bottom of the fixed base, a rotating base at the top of the fixed base, a water guide cover at the upper side of the rotating base, a rotating rod at the top of the rotating base, an extension mechanism at the outer side of the rotating rod, and a wind cup at one side of the extension mechanism.

[0006] The steering mechanism includes a rotating frame, with a rotating shaft rotatably connected to the inner side of the rotating frame, and a connecting rod fixedly connected to the outer side of the rotating shaft. The top of the connecting rod is fixedly connected to a fixed base, and a spring is provided at the lower side of the connecting rod. Limiting rods are fixedly connected to both ends of the spring. Limiting holes are provided on the side of the rotating frame near the limiting rods, and an installation mechanism is provided at the bottom of the rotating frame.

A retaining bolt is provided on the top of the perforated plate, and a nut is provided on the outside of the retaining bolt.

[0011] Preferably, a washer is provided on the top of the nut.

[0012] Preferably, a support plate is fixedly connected to one side of the perforated plate, and one side of the support plate is fixedly connected to the wind cup.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model is equipped with a steering mechanism. The rotating frame is fixed at the measuring position by clamps. In use, the two clamps are clamped to the wood or wall, the threaded holes are drilled, the mounting bolts are inserted and the nuts are tightened. The rotating shaft can rotate in the rotating frame to change the position of the connecting rod. When the limiting rod is in the limiting hole, the spring releases its elastic force to push the limiting rod into the limiting hole, thereby fixing the connecting rod and the air cup. The reinforcing rib can increase the rigidity of the clamps. The outer side of the pressure rod is provided with a wrapping angle. When the limiting rod is pressed to rotate the rotating shaft, the limiting rod can be more easily disengaged from the limiting hole. By fixing the air cup in the direction of the limiting hole, the range of use can be expanded.

When using it, it is necessary to determine the required length of the extension rod according to the installation position of the device, and then pull the perforated plate to change the distance between the wind cup and the rotating rod. Tightening the nut can fix the perforated plate. The washer can strengthen the connection between the nut and the locking bolt. The support plate provides support from the rear of the wind cup to prevent the connection between the wind cup and the perforated plate from breaking due to excessive wind speed. By pulling the perforated plate, the measurement radius can be changed according to the environment. Attached Figure Description

[0023] 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.

[0024] Example 1

[0025] Please see Figures 1-6 The present invention provides the following technical solution: an adaptive wind speed sensor for wind power generation, including a fixed base 1, a steering mechanism 2 at the bottom of the fixed base 1, a rotating base 3 at the top of the fixed base 1, a water guide cover 5 at the upper side of the rotating base 3, a rotating rod 4 at the top of the rotating base 3, an extension mechanism 6 at the outer side of the rotating rod 4, and a wind cup 7 at one side of the extension mechanism 6.

[0026] The steering mechanism 2 includes a rotating frame 21, a rotating shaft 22 is rotatably connected to the inner side of the rotating frame 21, a connecting rod 23 is fixedly connected to the outer side of the rotating shaft 22, the top of the connecting rod 23 is fixedly connected to the fixed base 1, a spring 24 is provided at the lower side of the connecting rod 23, and limit rods 25 are fixedly connected to both ends of the spring 24. A limit hole 26 is opened on the side of the rotating frame 21 near the limit rod 25, and an installation mechanism 27 is provided at the bottom of the rotating frame 21.

[0027] Specifically, the mounting mechanism 27 includes a clamping plate 271, with a mounting bolt 272 at the lower side of the clamping plate 271, and a nut 273 on the outside of the mounting bolt 272.

[0028] By adopting the above technical solution, the rotating frame 21 is fixed at the measurement position by the clamping plate 271. When in use, the two clamping plates 271 are clamped to the wood or wall, and then the threaded holes are drilled to insert the mounting bolt 272 and tighten the nut 273. The rotating shaft 22 can rotate inside the rotating frame 21, thereby changing the position of the connecting rod 23. When the limiting rod 25 is located in the limiting hole 26, the spring 24 releases its elastic force to push the limiting rod 25 into the limiting hole 26, thereby fixing the connecting rod 23 and the wind cup 7.

[0029] Specifically, the outer side of the clamp 271 is fixedly connected with a reinforcing rib 274.

[0030] By adopting the above technical solution, the stiffener 274 can increase the rigidity of the clamping plate 271.

[0031] Specifically, a pressure rod 28 is provided at the end of the limiting rod 25 away from the spring 24.

[0032] By adopting the above technical solution, the outer side of the pressure rod 28 is provided with a wrap angle. When the limit rod 25 is pressed to rotate the shaft 22, the limit rod 25 can be more easily disengaged from the limit hole 26.

[0033] In this embodiment, the wind force generated by airflow drives the wind cup 7 to rotate, which in turn drives the rotating rod 4 to rotate. The rotating rod 4 drives the connected sensing element to generate a pulse signal. Within the wind speed measurement range, the wind speed and the pulse frequency have a certain linear relationship, which can be used to calculate the wind speed. The rotating frame 21 is fixed at the measurement position by clamping plates 271. In use, the two clamping plates 271 are clamped to wood or a wall, threaded holes are drilled, mounting bolts 272 are inserted, and nuts 273 are tightened. The rotating shaft 22 can then rotate. The frame 21 rotates to change the position of the connecting rod 23. When the limiting rod 25 is in the limiting hole 26, the spring 24 releases its elastic force to push the limiting rod 25 into the limiting hole 26, thereby fixing the connecting rod 23 and the wind cup 7. The reinforcing rib 274 can increase the rigidity of the clamping plate 271. The pressure rod 28 has a wrapping corner on the outside. When the limiting rod 25 is pressed to rotate the shaft 22, the limiting rod 25 can be more easily disengaged from the limiting hole 26. By fixing the wind cup 7 in the direction of the limiting hole 26, the range of use can be expanded.

[0034] Example 2

[0035] The difference between this embodiment and embodiment 1 is that the extension mechanism 6 includes an extension rod 61, one end of which is fixedly connected to the rotating rod 4, and the other end of the extension rod 61 is slidably connected to a perforated plate 62. The end of the perforated plate 62 away from the extension rod 61 is fixedly connected to the wind cup 7. A locking bolt 63 is provided on the top of the perforated plate 62, and a nut 64 is provided on the outside of the locking bolt 63.

[0036] By adopting the above technical solution, the extension rod 61 rotates together with the rotating rod 4. When in use, it is necessary to determine the length of the extension rod 61 required according to the installation position of the device, and then pull the perforated plate 62 to change the distance between the wind cup 7 and the rotating rod 4. Tightening the nut 64 can fix the perforated plate 62.

[0037] Specifically, a washer 65 is provided on the top of the nut 64.

[0038] By adopting the above technical solution, the gasket 65 can strengthen the connection between the nut 64 and the locking bolt 63.

[0039] Specifically, a support plate 66 is fixedly connected to one side of the perforated plate 62, and one side of the support plate 66 is fixedly connected to the wind cup 7.

[0040] By adopting the above technical solution, the support plate 66 provides support from behind the wind cup 7 to prevent the wind speed from being too fast, which could cause the connection between the wind cup 7 and the perforated plate 62 to break.

[0041] In this embodiment, the extension rod 61 rotates together with the rotating rod 4. The required length of the extension rod 61 needs to be determined based on the device's installation location. The perforated plate 62 is then pulled to change the distance between the wind cup 7 and the rotating rod 4. Tightening the nut 64 secures the perforated plate 62. The washer 65 strengthens the connection between the nut 64 and the locking bolt 63. The support plate 66 provides support from behind the wind cup 7 to prevent excessive wind speed from causing breakage at the connection between the wind cup 7 and the perforated plate 62. By pulling the perforated plate 62, the measurement radius can be adjusted according to the environment.

[0043] The working principle and usage process of this utility model are as follows: When this utility model is in use, the wind force generated by the airflow drives the wind cup 7 to rotate. The wind cup 7 drives the rotating rod 4 to rotate, and the rotating rod 4 drives the connected sensing element to generate a pulse signal. Within the wind speed measurement range, the wind speed and the pulse frequency have a certain linear relationship, which can be used to calculate the wind speed. The rotating frame 21 is fixed at the measurement position by the clamping plate 271. In use, the two clamping plates 271 are clamped to wood or a wall, and then the threaded holes are drilled to insert the mounting bolt 272 and tighten the nut 273. The rotating shaft 22 can rotate within the rotating frame 21, thereby changing the position of the connecting rod 23. When the limiting rod 25 is located in the limiting hole 26, the spring 24 releases its elastic force to push the limiting rod 25 into the limiting hole 26, thereby fixing the connecting rod 23 and the wind cup 7. The reinforcing rib 274 can... The rigidity of the clamping plate 271 is increased, and the outer side of the pressure rod 28 is provided with a wrapping angle. When the limiting rod 25 is pressed to rotate the shaft 22, the limiting rod 25 can be more easily disengaged from the limiting hole 26. By fixing the wind cup 7 in the direction of the limiting hole 26, the range of use can be expanded. The extension rod 61 rotates together with the rotating rod 4. When using it, it is necessary to determine the length of the extension rod 61 according to the installation position of the device, and then pull the perforated plate 62 to change the distance between the wind cup 7 and the rotating rod 4. Tightening the nut 64 can fix the perforated plate 62. The washer 65 can strengthen the connection between the nut 64 and the locking bolt 63. The support plate 66 provides support from behind the wind cup 7 to prevent the connection between the wind cup 7 and the perforated plate 62 from breaking due to excessive wind speed. By pulling the perforated plate 62, the measurement radius can be changed according to the environment.
