Description

Technical Field

[0001] This invention relates to the field of wind power measurement technology, and in particular to a multi-angle wind power measurement device for a wind measurement tower. Background Technology

[0002] After China's wind power entered a stage of large-scale development, most of the large-scale wind power bases were located in the "Three Norths" region (Northwest, Northeast, and North China). These large-scale wind power bases are generally far from load centers, and their electricity needs to be transmitted over long distances and at high voltage to the load centers for consumption. Due to the intermittent, random, and fluctuating nature of wind resources, the wind power output of large-scale wind power bases will fluctuate significantly, further leading to fluctuations in the charging power of the transmission network and causing a series of problems for the safe operation of the power grid.

[0003] Therefore, it is necessary to build a series of wind measurement towers with real-time wind resource monitoring capabilities to form a wind measurement network, thereby monitoring wind resources in real time, improving the accuracy of wind power prediction, enabling dispatchers to adjust planned output in a timely manner, and ensuring the safe and stable operation of the power grid.

[0004] A search of Chinese patent CN111929465A reveals an anemometer. This patent discloses that a first magnetic levitation body can be suspended within a first magnetic base under the action of magnetic force and does not come into contact with the inner wall of the first magnetic base. In this embodiment, the first magnetic levitation body is connected to the wind direction detection mechanism, and the two rotate synchronously, so that the first magnetic levitation body and the wind direction detection mechanism will not generate friction during rotation.

[0005] However, the following problems exist in actual use: the magnetic levitation body will generate a certain levitation force due to the magnetic repulsion problem, but the wind vane needs to be installed at a certain height above the ground without any obstructions to be used to more accurately measure wind direction and speed. Due to the influence of high wind speed and the installation base, in the event of strong wind, the base and wind vane will sway and vibrate due to the wind force, causing the magnetic levitation body to deviate unstablely in the magnetic base. The equilibrium point cannot self-correct, causing the magnetic levitation body to always be tilted based on the center point of the magnetic base. In addition, Enshao's theorem states that a set of point particles cannot be stably maintained in a stable and static mechanical equilibrium structure composed only of the electrostatic interaction of charges. Therefore, the above solution urgently needs to be improved.

[0006] Therefore, this application provides a multi-angle wind power measurement device for a wind measurement tower to meet the requirements. Summary of the Invention

[0007] The purpose of this application is to provide a multi-angle wind power measurement device for a wind measurement tower to solve the problems mentioned in the background.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A multi-angle wind power measuring device for a wind measuring tower includes a wind measuring tower, a suspended cavity, a support plate, and a wind direction and speed measuring mechanism.

[0011] A sliding rod is installed on one side of the fixed base plate, and the other side of the sliding rod passes through the fixed base plate and is movably installed on one side of the second magnetic component. Guide grooves are respectively provided on one side of the first magnetic component, both sides of the fixed base plate, and both sides of the support plate, and pass through the surfaces of the first magnetic component, the fixed base plate, and the support plate. A second bearing is fixedly installed inside the guide groove on one side of the first magnetic component. A snap-fit ​​shaft is installed on the end face of the other side of the sliding rod. The snap-fit ​​shaft is fixed relative to the end face of the other side of the sliding rod. Snap-fit ​​blocks are symmetrically provided on both sides of the snap-fit ​​shaft. The second bearing has a snap-fit ​​groove inside that matches the snap-fit ​​block. Limit rods are installed on one side of the second bearing and one side of the snap-fit ​​shaft.

[0012] Preferably, the wind direction and speed measuring mechanism includes a mounting plate, a first protective sleeve, and a second protective sleeve. One side of the mounting plate is fixed to one side of the support plate. The first and second protective sleeves are fixedly installed on one side of the mounting plate. A linkage rod is slidably installed inside the first protective sleeve. One side of the linkage rod is installed inside the first protective sleeve, and the other side passes through the mounting plate and the support plate and is slidably installed on one side of the support plate.

[0013] Preferably, a telescopic component is installed inside the first protective sleeve, one end of which abuts against one side of the linkage rod; and an anemometer is installed inside the second protective sleeve, which is communicatively connected to the telescopic component.

[0014] Preferably, one side of the sliding rod passes through the suspension cavity and connects to one side of the linkage rod. An annular rotating plate is rotatably installed on one side of the second protective sleeve. A connecting plate is uniformly installed on one side of the annular rotating plate. A wind vane is fixedly installed on one side of the connecting plate. The wind vane has a first interlayer and a second interlayer inside. The first interlayer is located between the inner side of the wind vane and the outer side of the second interlayer.

[0015] Preferably, an electrostatic sheet is installed inside the first interlayer, the outer side of the wind vane is made of transparent material, a photosensitive element is installed inside the second interlayer, the photosensitive element is communicatively connected to the anemometer, the number of wind vanes is at least three sets, and the internal structure is adapted to the first interlayer, the second interlayer, the photosensitive element and the electrostatic sheet, and each set of photosensitive elements is electrically connected in series.

[0016] Preferably, a wind vane is installed on one side of the support plate, spline teeth are uniformly fixed on the surface of one side of the sliding rod, a spline sleeve is rotatably installed inside the guide groove on one side of the fixed base plate through a first bearing, the spline teeth are slidably installed inside the spline sleeve, a gap is left between the second bearing inside the guide groove on one side of the first magnetic component and the inner side of the guide groove on one side of the first magnetic component, and a resistance-increasing strip is installed between the gaps.

[0017] Preferably, the first magnetic component and the second magnetic component each have a groove on one side, and the groove contains particles made of low carbon steel or pure iron. One side of the groove is sealed by a sealing plate. There are six sets of conductive posts, with three sets of conductive posts fixed to both sides of the first magnetic component and parallel to each other.

[0018] Preferably, the inside of the guide groove on one side of the second magnetic component is in contact with the outside of the first bearing, and the spline sleeve and the first bearing are symmetrically installed inside the guide groove on one side of the second magnetic component along the centerline of the second magnetic component.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. In the above scheme, when the outer side of the levitation cavity is impacted by strong winds or when the wind tower and the levitation cavity are shaken by strong winds, the sliding rod located on one side of the second magnetic component slides towards the first magnetic component. This causes the locking shaft fixed to one end of the sliding rod to move in the same direction as the movement of the first magnetic component. The locking blocks fixed on both sides of the locking shaft are locked into the slots inside the second bearing inside the guide groove on one side of the fixed first magnetic component, providing stable support for the sliding rod. When the locking shaft is subjected to the moving force from the sliding rod, one side of the limiting rod is sleeved on the surface of the locking shaft on one end face of the sliding rod, and the other side is slidably installed on the surface of the second bearing. The movement direction of the locking shaft is guided, ensuring that the locking shaft and the locking blocks on both sides of the locking shaft can be accurately locked into the slots inside the second bearing. This effectively prevents the unstable displacement of the magnetic levitation body in the magnetic base mentioned in the background, the inability of the balance point to self-correct, and the problem that the magnetic levitation body is always tilted based on the center point of the magnetic base. This increases the stability of the sliding rod. This scheme has a simple structure and high practicality.

[0021] 2. In the above scheme, as the wind vane rotates due to wind speed, the electrostatic sheet located inside the first interlayer and outside the second interlayer operates and generates static electricity. Due to the static electricity generated by the electrostatic sheet, the photosensitive element inside the second interlayer illuminates. Dust in the wind covers the outside of the wind vane, slightly reducing the illumination received by the wind vane, thereby increasing the resistance of the photosensitive element inside the second interlayer. It is connected in series with the photosensitive element through an external wire. When the voltage of the photosensitive element is stable, the current in the external wire is inversely proportional to the resistance of the photosensitive element. The higher the resistance, the lower the current. The wind speed is detected simultaneously by an external current detector. Alternatively, the external wire can be connected in series with an external light. When the resistance of the photosensitive element increases due to the current in the external wire, the current in the circuit decreases, and the current in the external light also decreases, causing the external light to gradually dim, thus serving as a reminder to the user and improving the efficiency and stability of wind speed detection.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] refer to Figure 1-7 The multi-angle wind power measuring device for a wind measuring tower shown includes a wind measuring tower 1, a suspended cavity 2, a support plate 3, and a wind direction and speed measuring mechanism 4. The suspended cavity 2 is fixedly installed at one end of the wind measuring tower 1, and the suspended mechanism 5 installed inside the suspended cavity 2 provides protection. The support plate 3 is installed on one side of the suspended cavity 2, and the wind direction and speed measuring mechanism 4 is fixed on one side of the support plate 3. The suspended mechanism 5 is installed inside the suspended cavity 2.

[0034] The levitation mechanism 5 includes a first magnetic component 51, a conductive post 52, and an electromagnetic coil 53. The conductive post 52 is fixed to one side of the first magnetic component 51, and the electromagnetic coil 53 is uniformly wound around the surface of the conductive post 52. When the conductive post 52 is energized, a second magnetic component 54 is installed on one side of the interior of the levitation cavity 2. The second magnetic component 54 and the first magnetic component 51 are opposite to each other. One side of the first magnetic component 51 and the second magnetic component 54 are respectively connected to the two sides of the interior of the levitation cavity 2 through a fixed base plate 55.

[0035] A sliding rod 56 is installed on one side of the fixed base plate 55. The other side of the sliding rod 56 passes through the fixed base plate 55 and is movably installed on one side of the second magnetic component 54. Guide grooves 57 are provided on one side of the first magnetic component 51, both sides of the fixed base plate 55, and both sides of the support plate 3, and pass through the surfaces of the first magnetic component 51, the fixed base plate 55, and the support plate 3. A second bearing 59 is fixedly installed inside the guide groove 57 on one side of the first magnetic component 51. A snap-fit ​​shaft 58 is installed on the end face of the other side of the sliding rod 56. The snap-fit ​​shaft 58 is fixed relative to the end face of the other side of the sliding rod 56. Snap-fit ​​blocks are symmetrically provided on both sides of the snap-fit ​​shaft 58. A snap-fit ​​groove adapted to the snap-fit ​​block is opened inside the second bearing 59. Limit rods are installed on one side of the second bearing 59 and one side of the snap-fit ​​shaft 58.

[0036] In this embodiment, the first magnetic component 51 and the second magnetic component 54 include, but are not limited to, magnetic materials such as pure iron, permalloy, or bismuth, preferably bismuth. Bismuth has a certain antimagnetic repulsion force. When the first magnetic component 51 and the second magnetic component 54 are placed opposite each other, the space between them creates a space such as the repulsion of opposite magnetic poles, so that one side of the sliding rod 56 is stably suspended on one side of the conductive post 52.

[0037] Diamagnetism or diamagnetism will be repelled by a magnet. In other words, no matter whether the N pole or S pole of a magnet is close to a diamagnetic material, a repulsive force will be generated, and the magnitude of the force is basically inversely proportional to the square of the distance.

[0038] In the above scheme, during installation in windless weather, the first magnetic component 51 and the second magnetic component 54 are respectively fixed to the top and bottom of the suspension cavity 2 using a bolt assembly structure, wherein (refer to...) Figure 4As shown), the surfaces of the first magnetic component 51 and the second magnetic component 54, installed at the top and bottom of the suspension cavity 2, are respectively provided with mounting holes adapted to the conductive post 52. The conductive post 52 is installed inside the mounting holes provided on one side of the first magnetic component 51 and the second magnetic component 54. The electromagnetic coil 53 is wound around the surface of the conductive post 52 and is electrically connected to the electromagnetic coil 53 through an external coil. The conductive post 52 installed between the first magnetic component 51 and the second magnetic component 54 conducts current, providing stable suspension support for the sliding rod 56. The first magnetic component 51 and the conductive post The relative installation of 52 causes the repulsive force of the sliding rod 56 to increase when it approaches the side of the first magnetic component 51. (Whether it approaches the side of the first magnetic component 51 or the side of the second magnetic component 54, the repulsive force is inversely proportional to the square of the distance, and the change of this repulsive force with distance is greater than the change of the attractive force between the upper and lower first magnetic components 51 and the second magnetic component 54.) The middle becomes a stable equilibrium point. That is, due to the antimagnetism of the first magnetic component 51 and the second magnetic component 54, the sliding rod 56 is installed in the suspension cavity 2, and the sliding rod 56 will be suspended in the suspension cavity 2.

[0039] When the outer side of the suspension cavity 2 is impacted by strong winds, or when the wind measuring tower 1 and the suspension cavity 2 are impacted by strong winds and shake, the sliding rod 56 located on one side of the second magnetic component 54 slides towards the first magnetic component 51. This causes the locking shaft 58 fixed to one end of the sliding rod 56 to move in the same direction as the first magnetic component 51. The locking blocks fixed on both sides of the locking shaft 58 are locked into the slots inside the second bearing 59 inside the guide groove 57 on one side of the first magnetic component 51, providing stable support for the sliding rod 56. When the locking shaft 58 is subjected to the moving force from the sliding rod 56, one side of the limiting rod... The locking shaft 58 is sleeved on one end face of the sliding rod 56, and the other side is slidably mounted on the surface of the second bearing 59. The moving direction of the locking shaft 58 is guided to ensure that the locking shaft 58 and the locking blocks on both sides of the locking shaft 58 can be accurately locked into the inside of the second bearing 59 and the locking groove inside the second bearing 59. This effectively prevents the magnetic levitation body from becoming unstable and shifting in the magnetic base, as mentioned in the background, and the balance point from being unable to self-correct, causing the magnetic levitation body to always be tilted based on the center point of the magnetic base. This increases the stability of the sliding rod 56. This solution has a simple structure and high practicality.

[0040] As a preferred embodiment in this example (see...) Figure 3 , 6As shown in Figures 7 and 8, the wind direction and speed measuring mechanism 4 includes a mounting plate 41, a first protective sleeve 42, and a second protective sleeve 43. One side of the mounting plate 41 is fixed to one side of the support plate 3. The first protective sleeve 42 and the second protective sleeve 43 are fixedly installed on one side of the mounting plate 41. A linkage rod 44 is slidably installed inside the first protective sleeve 42. One side of the linkage rod 44 is installed inside the first protective sleeve 42, and the other side passes through the mounting plate 41 and the support plate 3 and is slidably installed on one side of the support plate 3. A telescopic component 45 is installed inside the first protective sleeve 42. One end of the telescopic component 45 abuts against one side of the linkage rod 44. An anemometer 46 is installed inside the second protective sleeve 43. The anemometer 46 and the telescopic component 45 are communicatively connected. The telescopic component 45 includes, but is not limited to, telescopic structures such as servo electric cylinders and solenoid valves.

[0041] In the above scheme, the anemometer 46 processes the wind speed and displays the value on an external display after comparison. When the anemometer 46 detects an abnormal wind speed value that is too high, the output end of the anemometer 46 sends a command signal to the input end of the telescopic component 45. The input end of the telescopic component 45 receives the command signal from the anemometer 46 and starts. One side of the output end of the telescopic component 45 moves towards the mounting plate 41 and abuts against one side of the linkage rod 44 located inside the mounting plate 41. This causes the other side of the linkage rod 44 to slide inside the first protective sleeve 42 and the mounting plate 41. Since one side of the sliding rod 56 passes through the suspension cavity 2 and connects to one side of the linkage rod 44, it causes the sliding rod 56 to slide along the vector direction inside the suspension cavity 2. This provides a power source for the sliding of the sliding rod 56, ensuring that when the outside of the suspension cavity 2 is impacted by strong winds or when the anemometer tower 1 and the suspension cavity 2 are impacted by strong winds and shake, the sliding rod 56 inside the suspension cavity 2 will shake.

[0042] In a preferred embodiment of this invention, an annular rotating plate 47 is rotatably mounted on one side of the second protective sleeve 43. A connecting plate is uniformly mounted on one side of the annular rotating plate 47. A wind vane 9 is fixedly mounted on one side of the connecting plate. The wind vane 9 has a first interlayer 91 and a second interlayer 92 inside. The first interlayer 91 is located between the inner side of the wind vane 9 and the outer side of the second interlayer 92. An electrostatic sheet 94 is installed inside the first interlayer 91. The outer side of the wind vane 9 is made of a transparent material, such as glass. A photosensitive element 93 is installed inside the second interlayer 92. The photosensitive element 93 is communicatively connected to the anemometer 46. The number of wind vanes 9 is at least three sets, and the internal structure is adapted to the first interlayer 91, the second interlayer 92, the photosensitive element 93 and the electrostatic sheet 94. Each set of photosensitive elements 93 is electrically connected in series.

[0043] In the above scheme, when the external wind speed increases, the annular rotating plate 47 installed on one side of the second protective sleeve 43 rotates along one side of the second protective sleeve 43, which in turn drives the connecting plate on one side of the annular rotating plate 47 to drive the wind direction ball 9 to rotate. The wind speed generated during the rotation of the wind direction ball 9 is sensed and transmitted by the anemometer 46 installed inside the second protective sleeve 43. The above structure is a common structure of existing technology reference anemometers and will not be described in detail.

[0044] As the wind vane 9 rotates due to wind speed, the electrostatic sheet 94 located inside the first interlayer 91, on the inside of the wind vane 9 and outside the second interlayer 92, operates and generates static electricity. Due to the static electricity generated by the electrostatic sheet 94, the photosensitive element 93 inside the second interlayer 92 emits light. Dust in the wind covers the outside of the wind vane 9, slightly reducing the amount of light received by the wind vane 9, which in turn increases the resistance of the photosensitive element 93 inside the second interlayer 92. The photosensitive element 93 is connected in series with an external wire. When the voltage of the photosensitive element 93 is stable, the current in the external wire is inversely proportional to the resistance of the photosensitive element 93. The greater the resistance, the smaller the current. The wind speed is detected simultaneously by an external current detector. Alternatively, the external wire can be connected in series with an external light. When the resistance of the photosensitive element 93 increases, the current in the circuit decreases, and the current in the external light also decreases, causing the external light to gradually dim, thus serving as a reminder to the user.

[0045] In this preferred embodiment, a wind vane is installed on one side of the support plate 3 to guide the airflow direction. Spline teeth 6 are uniformly fixed to one side of the sliding rod 56. A spline sleeve 7 is rotatably installed inside the guide groove 57 on one side of the fixed substrate 55 via a first bearing 8. The spline teeth 6 are slidably installed inside the spline sleeve 7, allowing the sliding rod 56 to slide along the guide groove 57 on one side of the fixed substrate 55, thus achieving the sliding condition for the sliding rod 56 installed inside the suspension cavity 2. A gap is left between the second bearing 59 inside the guide groove 57 on one side of the first magnetic component 51 and the inner side of the guide groove 57 on one side of the first magnetic component 51, and a resistance-increasing strip is installed between the gap to increase the fixed position of the sliding rod 56 and prevent the sliding rod 56 from shifting. The first magnetic component 51 and the second magnetic component 54 are respectively provided with grooves on one side. The grooves are filled with particles made of low carbon steel or pure iron. One side of the groove is sealed by a sealing plate to increase the magnetic stability between the first magnetic component 51 and the second magnetic component 54 in the above embodiment. There are six sets of conductive posts 52. Every three sets of conductive posts 52 are fixed on both sides of the first magnetic component 51 and are parallel to each other. The inside of the guide groove 57 on one side of the second magnetic component 54 fits against the outside of the first bearing 8. The spline teeth 6, spline sleeve 7 and the first bearing 8 are symmetrically installed along the center line of the second magnetic component 54 inside the guide groove 57 on one side of the second magnetic component 54. The sliding rod 56 can be adjusted in four directions using the guide groove 57, which has high compatibility.
