Abstract
Description
Technical Field
[0001] This utility model relates to the field of wind power generation technology, and in particular to a wind measuring device and a wind power plant. Background Technology
[0002] In the early stages of wind farm development, wind measurement towers are typically used to measure wind speeds, analyze wind resource parameters at pre-installed turbine locations, and calculate power generation. Wind resource analysis for wind farms requires flow field modeling based on wind measurement and topographic data to calculate wind resource parameters at pre-installed turbine locations.
[0003] Existing wind measurement towers typically employ truss-type wind measurement towers and laser wind measurement radar.
[0004] Truss-type wind measurement towers employ a steel truss structure, reinforced with guy wires for stability, and are erected on a concrete foundation. However, the high cost, long erection period, demanding terrain requirements, immobility, and non-reusability of truss-type wind measurement towers limit their flexibility. For projects with complex terrain, wind farms typically erect only one to three wind measurement towers, resulting in the inability to measure wind speeds in uncertain areas of the wind farm.
[0005] Compared to truss-type wind measurement towers, laser wind measurement radar has advantages such as shorter construction cycles, mobility, and reusability. It is typically used for supplementary wind measurement in the early stages of wind farm development, and in conjunction with truss-type towers, to analyze wind resource conditions. While laser wind measurement radar overcomes the limitations of truss-type towers in terms of immobility and non-reusability, it requires specific terrain and topography, and the transport of its auxiliary equipment, such as solar panels and batteries, is difficult, resulting in some uncertain areas in complex mountainous terrain still being unable to receive wind measurements. Furthermore, laser wind measurement radar is significantly affected by weather conditions (rain, fog, etc.), leading to a lower accuracy rate of valid wind measurement data. Utility Model Content

[0061] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0062] In the description of the embodiments of this utility model, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0063] The following is combined Figures 1 to 8 This invention describes the wind measuring device.
[0064] like Figure 1 and Figure 2 As shown, this utility model provides a wind measuring device, including a universal head base 1, a tower 2, a guy wire structure 4, and a wind measuring device 6.
[0065] The bottom end of the universal joint base 1 is detachably connected to the ground, facilitating the horizontal adjustment of the tower 2 and preventing the tower 2 from tilting due to the universal joint base 1 not being vertically aligned with the ground. Compared to traditional truss-type wind measurement towers where the foundation must be level to ensure the tower's rigidity and verticality, this invention uses the universal joint base 1 to adjust the verticality of the tower 2, effectively reducing the vertical correction process and increasing the installation tolerance.
[0066] The tower 2 includes an upright 21 and a support rod 22. The upright 21 is mounted on top of the universal joint base 1. Under the action of the universal joint base 1, the upright 21 is perpendicular to the horizontal plane, that is, the upright 21 is vertically positioned. The upright 21 is equipped with a directional indicator structure and a level 3. The directional indicator structure can be a compass or a north-pointing needle. The level is used to measure the tilt angle relative to the horizontal position to achieve horizontal leveling of the upright 21.
[0067] A support rod 22 is horizontally mounted on the tower 2, providing a mounting frame for the wind measuring device 6. The wind measuring device 6 is mounted on the support rod 22 and includes a wind speed device 61 and a wind direction device 62. The wind speed device 61 can be a wind speed sensor or an anemometer, capable of displaying the wind speed and wind volume at its location in real time. The wind direction device 62 can measure the wind direction.
[0068] In addition, this utility model also includes a lightning protection part 7, which is disposed at the top of the tower 2. The lightning protection part 7 includes a lightning rod 71 and a ceramic insulating sleeve 72. The ceramic insulating sleeve 72 is disposed at the bottom of the outer periphery of the lightning rod 71 and is used to isolate the strong current brought by lightning.
[0069] It should be noted that traditional iron towers use the tower body as a conductor and are grounded through lightning protection flat iron. This utility model uses a ceramic insulating sleeve 72 to insulate and isolate the lightning rod 71 from the tower 2. The lightning rod 71 is grounded through a lightning protection wire. This design protects the wind measuring equipment 6 on the tower 2 from damage by lightning strikes.
[0070] The wind measuring device provided by this utility model, compared with the traditional truss-type wind measuring device, has a shorter tower erection period, lower terrain requirements, and is movable and reusable. In addition, the wind measuring device of this utility model is a physical wind measuring device, which is less affected by weather and has no auxiliary equipment such as solar panels and batteries compared with lidar wind measuring devices. It is convenient to transport, has a short construction period, and has low terrain requirements, providing effective support for short-term multi-point wind measurement work. It can conduct short-term multi-point wind measurement in complex mountainous uncertain areas, and use the correlation of multiple points in uncertain areas at the same time to verify and calibrate the flow field model, thereby reducing the uncertainty of wind resource assessment.
[0071] like Figure 2As shown, the guy wire structure 4 includes a rotatable guy wire ring 41, at least three force-directing structures 42, and a guy wire 43. The rotatable guy wire ring 41 is sleeved on the outer circumference of the upright 21 and can rotate horizontally relative to the upright 21, used to connect the guy wire 43 to stabilize the upright 21. The principle of the rotatable guy wire ring 41 is to apply vertical downward pressure and lateral tension to the upright 21 through ball bearings while ensuring the upright 21 can be rotated and adjusted, thus ensuring the stable support of the upright 21. Moreover, the setting of the rotatable guy wire ring 41 makes it easy to adjust the placement of the anemometer without being affected by the fixed guy wire. When the guy wire 43 applies vertical downward pressure to the upright 21, it can rotate the upright 21, thereby adjusting the placement direction of the anemometer so that the anemometer points north.
[0072] One end of the pull wire 43 is connected to the rotatable pull wire ring 41, passes through the force steering structure 42 and is connected to the ground to fix the upright pole 21.
[0073] like Figure 2 As shown, one end of the force steering structure 42 is connected to the rotatable pull cord ring 41 at a first connection point, and the other end is connected to the ground at a second connection point. The first and second connection points are located on the same side of the force steering structure 42. The force steering structure 42 changes the direction of force through the lever principle, thus reducing the area of the installation platform. In this embodiment, the force steering structure 42 can be a fixed pulley or other structural forms, as long as it can achieve the steering of the pull cord 43.
[0074] More advantageous, such as Figure 3 and Figure 4 As shown, the force steering structure 42 may include a force steering rod 421 and a force steering wedge 422. The bottom of the force steering rod 421 is detachably connected to the ground. The bottom of the force steering rod 421 is designed with a tapered tip structure. The tip structure can reduce the contact area between the bolt and the soil, reduce the resistance when the bolt enters the soil, and thus make it easier to drive the force steering rod 421 into the soil. The force steering wedge 422 is set on the top of the force steering rod 421. The force steering wedge 422 and the force steering rod 421 are hinged to the first through hole 423. The force steering wedge 422 is also provided with a second through hole 424 and a third through hole 425. The second through hole 424 is used to pass through the first pull wire, which is used to connect with the rotatable pull wire ring 41. The third through hole 425 is used to pass through the second pull wire, which is used to connect with the ground. The first pull wire and the second pull wire are two different pull wires 43.
[0075] like Figure 2 and Figure 3As shown, in the above embodiment, the distance from the foundation of the conventional route to the center of the wind measuring device is L1. By setting the foundation of the force-directing structure 42 to the center of the wind measuring device is L2, the construction platform area can be reduced by setting the force-directing structure 42. The tension of the wind measuring tower guy wire is F1, and the lever arm acting on the fulcrum is M1. The tension of the improved guy wire anchor is F2, and the lever arm acting on the fulcrum is M2. According to the balance of force and lever arm: F1*M1=F2*M2; it is concluded that the tension of the guy wire anchor F2=F1*(M1 / M2). Since the force-directing support rod can withstand a large vertical downward pressure and lateral force, but can withstand a small upward pull force, this device can reduce the upward pull force of the guy wire anchor.
[0076] It should be noted that M1 and M2 are the perpendicular distances from the center of rotation to the force.
[0077] like Figure 2 and Figure 5 As shown, in one embodiment of this utility model, a guy wire anchor 5 is also included. The guy wire anchor 5 is used to connect the second guy wire, and the guy wire anchor 5 can be detachably fixed to the ground, which facilitates the fixing of the second guy wire. The anchor is fixed by physical expansion after it is driven into the ground.
[0078] In one embodiment of this utility model, the guy wire anchor 5 may include an expansion bolt 51, a first steering ring 52, a second steering ring 53, a steering ring clamping nut 54, and a pull ring 55. The bottom of the expansion bolt 51 is designed with a conical tip structure. This tip structure reduces the contact area between the bolt and the soil, lowering the resistance when the bolt enters the soil, thus making it easier to enter the soil. Then, tightening the steering ring clamping nut 54 expands the expansion plate, fixing it in the ground. The first steering ring 52 is rotatably disposed on the top of the expansion bolt 51, and its rotation axis is a first axis. The first steering ring 52 is used to allow the pull ring 55 to rotate in a horizontal plane. The second steering ring 53 is rotatably disposed on the outer periphery of the first steering ring 52, and its rotation axis is a second axis, which is perpendicular to the first axis. The second steering ring 53 is used to allow the pull ring 55 to rotate in a vertical plane, enabling the pull ring 55 to rotate freely in two mutually perpendicular planes. The pull ring 55 is rotatably positioned at the end of the second steering ring 53 away from the first steering ring 52, and the pull ring 55 is convenient to connect with the second pull cable.
[0079] Furthermore, due to the rotatable pull ring 41, it does not affect the use when the pull line 43 is not aligned with the pull line anchor 5. The pull line anchor 5 can be adjusted without adjusting it by rotating the rotatable pull ring 41.
[0080] like Figure 6 and Figure 7As shown, in one embodiment of this utility model, the guyed anchor 5 further includes a guyed tension adjusting device 56, which is disposed between the second steering ring 53 and the pull ring 55, and is used to adjust the tension of the pull ring 55. The guyed tension adjusting device 56 can adjust the tension of the guyed line through the principle of reverse thread. The thread is selected as self-locking type to prevent loosening due to vibration.
[0081] In one embodiment of this utility model, the tension adjustment device 56 may include an adjusting nut 561 and an adjusting screw 562. One end of the adjusting nut 561 is connected to the second steering ring 53; the adjusting screw 562 passes through the pull ring 55 and is adapted to be connected to the adjusting nut 561. By rotating the adjusting nut 561, the tension of the pull wire 43 is adjusted, which facilitates the adjustment of the verticality.
[0082] In one embodiment of this utility model, the upright 21 is a telescopic pole, which has good portability. The tower 2 can be made up of multiple nested parent and child poles with progressively increasing diameters, which facilitates telescopic fixing, facilitates the unfolding and transportation of the support pole 22, and also allows for adjustment of the wind measuring height of the wind measuring device.
[0083] To ensure the stability of the upright 21 after it is extended, a limiting structure can be set inside the upright 21 to achieve self-locking of the length of the upright 21. The limiting structure can be any structural form, as long as it can achieve self-locking of the upright 21, and no specific limitation is made here.
[0084] like Figure 8 As shown, in one embodiment of this utility model, a universal joint 201 is provided at the bottom of the upright 21. The universal joint 201 can be configured as a bowl-shaped structure. The universal joint base 1 includes a connecting part 101, a ball head 102, and a locking sleeve 103. The connecting part 101 is used to connect to the ground and can be an expansion bolt or other structural forms. The ball head 102 is located at the top of the connecting part 101 and is adapted to the universal joint 201. The bowl-shaped universal joint 201 is inverted and placed on the ball head 102, which can be used to adjust the verticality of the tower 2 during the installation of the side sealing device. The locking sleeve 103 is sleeved on the outer periphery of the ball head 102 and the universal joint 201. The locking sleeve 103 is used to limit the rotation of the universal joint 201 and to lock it after the wind measuring device has been adjusted for north and verticality.
[0085] The installation process of this utility model is as follows:
[0086] Select the installation location for the wind measurement device in advance;
[0087] Place the locking sleeve 103 onto the ball head 102, and use a tool to screw the connecting part 101 into the ground to ensure that the ball head 102 is above the ground plane.
[0088] Extend the upright 21 of the telescopic pole to the specified length;
[0089] Install the support rod 22 on the upright 21, and place the support rod 22 horizontally;
[0090] Install the wind speed device 61 and the wind direction device 62 to both ends of the support rod 22, so that the original azimuth angles of the wind speed device 61 and the wind direction device 62 are perpendicular to the support rod 22.
[0091] A lightning rod 71 and a ceramic insulating sleeve 72 are installed at the top of tower 2;
[0092] At least three first pull wires are fixed at one end to the three rings of the rotatable pull wire ring 41 respectively;
[0093] Place the upright pole 21 on the universal joint 201, so that the ball head 102 is combined with the bowl-shaped structure of the universal joint 201, and tighten the locking sleeve, but do not tighten it yet;
[0094] By observing the compass, ensure that the zero point of the wind direction equipment points north, and complete the north orientation of the wind measuring device; and tighten the locking sleeve 103.
[0095] The rotatable guy ring 41 is used to adjust the guy wire arrangement to a more suitable position, and the installation positions of the force steering structure 42 and the guy wire ground anchor 5 are determined.
[0096] Install force steering support rod 421 and force steering wedge 422 to ensure that the final position of force steering structure 42 is on the same plane as the upright rod 21. Ropes are used to facilitate wire fixation and stability.
[0097] Install the guy wire ground anchor 5 and tighten the steering ring nut 54 to fix the ground anchor;
[0098] The other end of each first pull wire is passed through the force steering wedge 422 and fixed to the force steering wedge 422. One end of the second pull wire is fixed to the force steering wedge 422 and the other end is fixed to the pull ring 55. The verticality of the pole 21 is initially determined by using a level.
[0099] By observing the level, adjust the adjusting nuts 561 on the three tension adjustment devices 56 to make the upright 21 perpendicular to the horizontal plane, thus completing the vertical adjustment of the wind measuring device;
