[0039] The following describes the specific implementation of the embodiment of the present invention in detail with reference to the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the embodiment of the present invention and is not used to limit the embodiment of the present invention.
[0040] In the embodiments of the present invention, unless otherwise specified, directional words such as "up, down, left, right" generally refer to the orientation or position relationship shown in the accompanying drawings, or the orientation or position relationship in which the product of the invention is usually placed when in use.
[0041] The terms "first", "second", "third", etc. are only used for distinction and description and should not be understood as indicating or implying relative importance.
[0042] The terms "parallel" and "perpendicular" do not necessarily mean that the components must be absolutely parallel or perpendicular, but rather that they can be slightly tilted. For example, "parallel" simply means that the direction is more parallel than "perpendicular", not that the structure must be completely parallel, but rather that it can be slightly tilted.
[0043] Terms such as "horizontal," "vertical," and "overhanging" do not necessarily mean that a component must be absolutely horizontal, vertical, or overhanging. A slight tilt is permitted. For example, "horizontal" simply means that its direction is more horizontal than "vertical." It does not mean that the structure must be completely horizontal, but rather that a slight tilt is permitted.
[0044] Furthermore, terms like "approximately" and "substantially" are intended to clarify that the relevant content does not require absolute precision, but rather allows for certain deviations. For example, "approximately equal" does not simply mean absolute equality. Because absolute equality is difficult to achieve in actual production and operational processes, certain deviations generally exist. Therefore, in addition to absolute equality, "approximately equal" also encompasses the aforementioned situation of certain deviations. Taking this as an example, in other contexts, unless otherwise specified, terms like "approximately" and "substantially" have similar meanings as described above.
[0045] In the description of the present invention, it should also be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.
[0046] Figure 1 2 is a structural block diagram of the wind turbine impeller hoisting and cable wind system provided by the present invention; FIG. 3 is a structural block diagram of the wind turbine impeller hoisting and cable wind system provided by the present invention.
[0047] like Figure 1-2 As shown, this embodiment provides a wind turbine rotor hoisting and cable wind system, comprising:
[0048] A first actuator 1 and a second actuator 2 are independently arranged, wherein the first actuator 1 is connected to a first blade 102 of the wind turbine generator set via a first guy cable 101, and the second actuator 2 is connected to a second blade 104 of the wind turbine generator set via a second guy cable 103;
[0049] a signal detection mechanism 3, configured to obtain angle signals and acceleration signals of the first blade 102 and the second blade 104, and tension signals of the first guy rope 101 and the second guy rope 103;
[0050] a control mechanism 4 connected to the first actuator 1, the second actuator 2, and the signal detection mechanism 3, and configured to obtain the angle and acceleration of the first blade 102, the angle and acceleration of the second blade 104, and the tension of the first guy rope 101 and the second guy rope 103 based on the received angle signal, acceleration signal, and tension signal; and further configured to control the first actuator 1 and / or the second actuator 2 to adjust the rotation direction, rotation speed, and rotation angle of the corresponding blade based on a control instruction received from the mobile terminal 5;
[0051] The mobile terminal 5 is communicatively connected to the control mechanism 4 and is used to receive and display the angle and acceleration of the first blade 102, the angle and acceleration of the second blade 104, and the tension of the first cable guy rope 101 and the second cable guy rope 103. The mobile terminal 5 is also used to generate the control instruction according to the external input instruction and send the control instruction to the control mechanism 4.
[0052] Specifically, during the wind-cable process, after the three blades are installed on the impeller, the first wind rope 101 is One end of the first guy rope 101 is connected to the first blade 102 of the wind turbine generator set, and one end of the second guy rope 103 is connected to the second blade 104 of the wind turbine generator set. The other end of the first guy rope 101 is connected to the first actuator 1, and the other end of the second guy rope 103 is connected to the second actuator 2. The first actuator 1 and the second actuator 2 are respectively located at the two ends of the impeller (if the actual environment permits, preferably consistent with the direction of rotation of the impeller). The impeller is lifted by a crane. During the lifting process, the tips of the first blade and the second blade are ensured to face upward. After being lifted to a certain position, the telescopic length of the first guy rope 101 can be adjusted by the first actuator 1, and the telescopic length and telescopic speed of the second guy rope 103 can be adjusted by the second actuator 2 to achieve the adjustment of the impeller rotation angle, that is, the adjustment of the corresponding blade rotation direction, rotation speed and rotation angle, so that the impeller can be installed in line with the engine; in addition, the signal detection mechanism 3 is set to be able to obtain the angle signals of the first blade 102 and the second blade 104 , acceleration signals, and tension signals of the first and second guy ropes 101, 103, and the collected signals are sent to the control mechanism 4 through the wireless signal sending module. The control mechanism 4 is provided with a corresponding wireless signal receiving module. According to the received angle signal, acceleration signal and tension signal, the angle and acceleration of the first blade 102, the angle and acceleration of the second blade 104, and the tension of the first and second guy ropes 101, 103 are obtained, and the obtained angle, acceleration and tension are sent to the mobile terminal 5. The mobile terminal 5 is configured to the operator. The mobile terminal 5 displays the real-time received angle and acceleration of the first blade 102, the angle and acceleration of the second blade 104, and the tension of the first and second guy ropes 101, 103. The operator can input external input instructions to the mobile terminal 5 through the buttons on the mobile terminal 5 according to the displayed data to generate control instructions, and send the control instructions to the control mechanism 4. The control mechanism 4 It is also used to control the first actuator 1 and / or the second actuator 2 to adjust the rotation direction, rotation speed and rotation angle of the corresponding blades according to the control instructions received from the mobile terminal 5, so as to achieve precise control of the impeller posture, and the impeller lifting efficiency is high, the wind resistance is strong, manpower is saved, and the use cost is reduced.
[0053] The control mechanism 4 includes a control cabinet and a storage module. The controller can process data. For example, the control device can be a programmable logic controller (PLC). The storage module stores received and sent data.
[0054] The wireless communication between the wireless data sending module and the wireless data receiving module can adopt Bluetooth wireless communication, ZigBee wireless communication, mobile communication, etc.
[0055] Furthermore, the first guy rope 101 is detachably connected to the first blade 102 of the wind turbine generator set through the first blade tip sheath 61 ; the second guy rope 103 is detachably connected to the second blade 104 of the wind turbine generator set through the second blade tip sheath 62 .
[0056] Specifically, in this embodiment, the connection between the guy rope and the blade is achieved through the blade tip sheath. When in use, the blade tip sheath is directly put on the corresponding first blade 102 and the second blade 104, which is convenient for disassembly. Moreover, the connection between the blade tip sheath and the blade can increase the contact area, disperse the contact pressure, and provide better protection for the blade. In addition, the first guy rope 101 is hinged to the first blade tip sheath 61, and the second guy rope 103 is hinged to the second blade tip sheath 62.
[0057] Furthermore, the first actuator 1 is electrically connected to the control mechanism 4 via a first frequency converter 71 ; the second actuator 2 is electrically connected to the control mechanism 4 via a second frequency converter 72 .
[0058] Specifically, during the cable wind process, due to the different deflection angles of the impeller and certain differences in wind direction, the adjustment levels of the first actuator 1 and the second actuator 2 are also different during the adjustment process. Therefore, the first actuator 1 is electrically connected to the control mechanism 4 through the first frequency converter 71; the second actuator 2 is electrically connected to the control mechanism 4 through the second frequency converter 72, so as to achieve targeted independent adjustment of the first actuator 1 and the second actuator 2.
[0059] Furthermore, the first actuator 1 includes:
[0060] a first supporting platform, wherein a first hoist is provided on the first supporting platform and the first hoist is connected to a first guy rope;
[0061] The second actuator 2 includes:
[0062] a second supporting platform, wherein a second hoist is provided on the second supporting platform and the second hoist is connected to a second guy rope;
[0063] Specifically, in this embodiment, the first support platform is used to support the first winch, the winch of the first winch is connected to the first cable wind rope, and the first winch is electrically connected to the first frequency converter 71. The speed of the first winch can be adjusted according to the frequency conversion signal of the first frequency converter 71, thereby adjusting the extension and retraction amount of the first cable wind rope 101. The control of the second actuator 2 is implemented in the same way and will not be repeated here.
[0064] Furthermore, a plurality of rollers are provided at intervals on the lower end surfaces of the first supporting platform and the second supporting platform.
[0065] Specifically, the first actuator 1 and the second actuator 2 themselves have a certain weight, and since wind turbines are usually installed in a wild environment, it is difficult to move the first actuator 1 and the second actuator 2 by manpower. Therefore, four rollers are correspondingly provided on the lower end surfaces of the first support platform and the second support platform. Usually, four rollers are respectively provided on the lower end surfaces of the first support platform and the second support platform, and the four rollers are respectively spaced apart and arranged at the edges of the first support platform and the second support platform to facilitate the movement of the first actuator 1 and the second actuator 2.
[0066] Furthermore, a plurality of hydraulic lifting mechanisms are provided at intervals on the lower end surfaces of the first supporting platform and the second supporting platform.
[0067] Specifically, since wind turbines are typically installed outdoors, the first and second actuators 1 and 2 may be used in environments with uneven roads. Therefore, in this embodiment, multiple hydraulic lifting mechanisms are spaced apart on the lower end surfaces of the first and second support platforms. Typically, four hydraulic lifting mechanisms are provided on the lower end surfaces of each of the first and second support platforms, and the four hydraulic lifting mechanisms are spaced apart at the edges of the first and second support platforms to increase the stability of the first and second actuators 1 and 2. During use, after the first and second actuators 1 and 2 are moved to corresponding positions and their orientations adjusted according to the actual environment, a level meter can be used to check whether the first and second actuators are level. The lifting heights of the corresponding hydraulic lifting mechanisms can then be adjusted to maintain the first and second actuators 1 and 2 level and stable.
[0068] Furthermore, the signal detection mechanism 3 includes:
[0069] A first detection mechanism 31 is provided on the first blade 102 and the second blade 104 and is used to obtain angle signals and acceleration signals of the first blade 102 and the second blade 104;
[0070] The second detection mechanism 32 is provided on the first guy rope 101 and the second guy rope 103 , and is used to obtain tension signals of the first guy rope 101 and the second guy rope 103 .
[0071] Furthermore, the first detection mechanism 31 includes at least two angle sensors and at least two acceleration sensors;
[0072] The first blade 102 is provided with at least one angle sensor and at least one acceleration sensor;
[0073] At least one angle sensor and at least one acceleration sensor are disposed on the second blade 104 .
[0074] In this embodiment, preferably, an angle sensor and an acceleration sensor are provided on the first blade 102, and an angle sensor and an acceleration sensor are provided on the second blade 104. Alternatively, the angle sensor and the acceleration sensor can be attached to the corresponding first blade 102 and second blade 104 by gluing. The angle sensor and the acceleration sensor are each provided with a corresponding wireless signal transmission module to transmit the collected signals to the control mechanism 4.
[0075] Furthermore, the second detection mechanism 32 includes at least two tension sensors;
[0076] At least one tension sensor is provided on the first guy rope 101;
[0077] At least one tension sensor is provided on the second guy rope 103 .
[0078] In this embodiment, preferably, a tension sensor is provided on the first guy rope 101; a tension sensor is provided on the second guy rope 103, and the tension sensors are provided at the ends of the first guy rope 101 and the second guy rope 103 close to the pressure blades, and the tension sensors are provided with corresponding wireless signal sending modules to send the collected signals to the control mechanism 4.
[0079] Furthermore, the control mechanism 4 is further configured to generate an alarm signal when the tension value of the first guy rope 101 and the tension value of the second guy rope 103 are both greater than a preset tension threshold, and send the alarm signal to the mobile terminal 5, and simultaneously control the first actuator 1 and the second actuator 2 to stop working;
[0080] The mobile terminal 5 is further configured to generate an audible and visual alarm based on the alarm signal received from the control mechanism 4 .
[0081] Specifically, since in actual use, the first guy rope 101 and the second guy rope 103 may be retracted at the same time, and there may be human operational errors, causing the first guy rope 101 and the second guy rope 103 to retract. However, retracting the first guy rope 101 and the second guy rope 103 at the same time may increase the pressure on the blades. Therefore, in this embodiment, when the control mechanism 4 detects that the tension value of the first guy rope 101 and the tension value of the second guy rope 103 are both greater than the preset tension threshold, an alarm signal is generated, and the first actuator 1 and the second actuator 2 are immediately controlled to stop working to avoid further retraction of the first guy rope 101 and the second guy rope 103, which may cause damage to the blades; at the same time, the generated alarm signal is sent to the mobile terminal 5, and the mobile terminal 5 generates an audible and visual alarm based on the alarm signal received from the control mechanism 4.
