Description

Technical Field

[0001] This application belongs to the field of wind power generation technology, specifically relating to a wind turbine generator simulation device. Background Technology

[0002] Wind power generation uses wind energy to drive the blades to rotate, which in turn drives the generator's main shaft to rotate, thus generating electricity. To improve power generation efficiency, the angle of the blades needs to be adjusted according to the wind speed so that the blades are in the optimal working condition.

[0004] Before the aforementioned rotating turbine head is installed on the wind power generation equipment, its performance needs to be tested. The rotating turbine head is installed on the rotating shaft of the simulation device, and the rotating shaft is driven to rotate by a motor, which in turn drives the rotating turbine head to rotate, simulating the working condition of wind driving the rotating turbine head to rotate. Then, during the rotation of the rotating turbine head, the blade angle is adjusted.

[0005] During the installation of the rotating head onto the simulation device, the rotating head is hoisted by hoisting equipment to keep it suspended in the air until it is installed onto the simulation device. Because the rotating head is suspended in the air, it is not convenient to position the rotating head for installation. Utility Model Content

[0007] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0008] A wind turbine generator simulation device is provided, comprising:

[0009] The support frame has a drive mechanism connected to one end and a support structure rotatably connected to the other end; the drive end of the drive mechanism and the support structure are respectively connected to the flanges at both ends of the rotating head.

[0010] A support component is disposed between the drive mechanism and the support structure, and located directly below the rotating head; the top of the support component has an arc surface, and several rollers are rotatably disposed on the arc surface, which rotate in cooperation with the outer peripheral wall of the rotating head, so as to adjust the installation position of the rotating head circumferentially.

[0011] The supporting component has a degree of freedom to move laterally, so as to adjust the installation position of the rotating head radially; the supporting component also has a degree of freedom to move up and down, so that the supporting component can be separated from the rotating head after the rotating head is installed in place.

[0012] In one possible implementation, the support component includes a sliding seat and an arc-shaped plate. The sliding seat is laterally slidably disposed on the support frame. The sliding seat has a power component for lifting the arc-shaped plate, and rollers are disposed on the concave surface of the arc-shaped plate.

[0013] In one possible implementation, the rotary head has a first housing and a second housing, with a flange connection between the first housing and the second housing, and the flange at the connection between the first housing and the second housing forms a positioning ring;

[0014] One end of the arc-shaped plate has an L-shaped plate that is inserted into and fits with the positioning ring. A slot is formed between the ends of the L-shaped plate and the arc-shaped plate. The two opposite sides of the slot contact the two ends of the positioning ring to axially limit the rotation of the machine head.

[0015] In one possible implementation, the arc-shaped plate has a relief groove symmetrical about the arc surface at one end of the slot, and when the arc-shaped plate slides down to the position where it is separated from the rotating head, there is a gap between the relief groove and the positioning ring.

[0016] In one possible implementation, the support frame has a transverse slide rail, and the bottom of the sliding seat has a groove that mates with the transverse slide rail.

[0017] A screw is rotatably mounted on the support frame, and one end of the screw is connected to the output shaft of the transverse drive motor; the sliding seat has a threaded through hole that is threaded to engage with the screw.

[0018] In one possible implementation, two positioning components are connected to the transverse slide rail, the length between the two positioning components being the stroke of the slide seat; both positioning components have through holes for rotating with the screw.

[0019] In one possible implementation, the sliding seat has an internal accommodating cavity, and the power component is disposed within the accommodating cavity; the bottom of the arc-shaped plate has an insert, and the lifting end of the power component is inserted into the insert.

[0020] In one possible implementation, the power components are in two sets, and the two sets of power components are symmetrically arranged about the axis of the arc plate; the top of the sliding seat has an abutment surface that contacts the bottom of the arc plate, and when the sliding seat slides down to the position where it is separated from the rotating head, the bottom of the rotating head contacts the abutment surface of the sliding seat.

[0021] In one possible implementation, the concave surface of the arc-shaped plate has a placement groove for placing a roller, and the two sides of the placement groove have insertion holes, one of which communicates with the end of the arc-shaped plate.

[0022] The roller has a through hole aligned with the insertion hole. When the roller is located in the placement groove, the through hole of the roller is aligned with the insertion hole, and the rotating shaft is inserted into the insertion hole and the through hole of the roller so that the roller rotates around the rotating shaft.

[0023] In one possible implementation, the support structure includes:

[0025] A rotating shaft passes through the support and is rotatably engaged with the support; the two ends of the rotating shaft passing through the support have limiting discs, which contact the two sides of the support to axially limit the position of the rotating shaft.

[0026] A flange is connected to the rotating shaft.

[0027] This application provides a wind turbine generator simulation device. Compared with the prior art, when testing the rotating turbine head, the support component is located away from the drive mechanism and support structure. The rotating turbine head is then hoisted onto the support component. By adjusting the axial position of the rotating turbine head, it is positioned between the drive mechanism and support structure. The support component drives the rotating turbine head to move laterally between the drive mechanism and support structure. The operator rotates the rotating turbine head to align the holes on one end flange of the rotating turbine head with the holes on the drive end flange, facilitating the connection between the rotating turbine head and the drive end flange. The operator rotates the support structure to align the holes on the flange of the support structure with the holes on the flange of the other end of the rotating turbine head, facilitating the connection between the rotating turbine head and the support structure flange. When the rotating turbine head is fixed between the drive mechanism and support structure, the support component slides downward and separates from the rotating turbine head, preventing friction between the rotating turbine head and the support component during rotation. Through the above-mentioned configuration, the rotating turbine head is easily positioned, thus facilitating its installation between the drive mechanism and support structure.

[0037] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0038] Please refer to the following: Figures 1 to 8This application describes a wind turbine generator simulation device. The wind turbine generator simulation device includes a support frame 1 and a support component 2. One end of the support frame 1 is connected to a drive mechanism 3, and the other end is rotatably connected to a support structure 4. The drive end of the drive mechanism 3 and the support structure 4 are respectively connected to the flanges at both ends of a rotating turbine head 5. The support component 2 is disposed between the drive mechanism 3 and the support structure 4, and is located directly below the rotating turbine head 5. The top of the support component 2 has an arc surface, on which several rollers 21 are rotatably disposed, cooperating with the outer peripheral wall of the rotating turbine head 5, to adjust the installation position of the rotating turbine head 5 circumferentially. The support component 2 has a lateral movement degree of freedom to adjust the installation position of the rotating turbine head 5 radially. The support component 2 also has a lifting degree of freedom, allowing it to separate from the rotating turbine head 5 after it is installed in place. In this application, the lateral movement direction refers to the direction perpendicular to the axis of the rotating turbine head 5 on a horizontal plane.

[0039] This application provides a wind turbine generator simulation device. Compared with the prior art, when testing the rotating turbine head 5, the support component 2 is located away from the drive mechanism 3 and the support structure 4. Then, the rotating turbine head 5 is hoisted onto the support component 2. By adjusting the axial position of the rotating turbine head 5, it is positioned between the drive mechanism 3 and the support structure 4. The support component 2 drives the rotating turbine head 5 to move laterally between the drive mechanism 3 and the support structure 4. The operator rotates the rotating turbine head 5 to align the holes of one end flange of the rotating turbine head 5 with the holes of the drive end flange, facilitating the interaction between the rotating turbine head 5 and the drive mechanism 4. The end flange is connected; when the operator rotates the support structure 4, the hole on the flange of the support structure 4 can be aligned with the hole on the flange at the other end of the rotating head 5, which facilitates the flange connection between the rotating head 5 and the support structure 4; when the rotating head 5 is fixed between the drive mechanism 3 and the support structure 4, the support component 2 slides downward and separates from the rotating head 5, which can prevent friction between the rotating head 5 and the support component 2 when the rotating head 5 rotates; through the above-mentioned settings of this application, it is convenient to position the rotating head 5, and thus convenient to install the rotating head 5 between the drive mechanism 3 and the support structure 4.

[0040] The rotating head 5 has a first housing 51 and a second housing 52, which are connected by a flange. The flange at the connection between the first housing 51 and the second housing 52 forms a positioning ring 53. The outer peripheral wall of the first housing 51 has nine sleeves 54, and a drive shaft 55 extends from each sleeve 54. The adjustment structure inside the rotating head 5 is existing technology and will not be described in detail here. A mobile power supply can be installed inside the rotating head 5 to supply power to the drive motor inside the rotating head 5.

[0041] The drive mechanism 3 includes a test motor, which is mounted on the support frame 1; the output shaft of the test motor is connected to the input shaft of the reducer via a coupling, and the output shaft of the reducer is connected to a flange.

[0042] To facilitate observation of the angle change of the drive shaft 55, an angle iron (not shown in the figure) can be fixed to the end of the drive shaft 55 with bolts. The degree of deflection of the angle iron can be used to visually observe the angle change of the drive shaft 55.

[0043] The support structure 4 includes a support 41, a rotating shaft 42, and a flange. The support 41 is connected to the support frame 1. The rotating shaft 42 passes through the support 41 and is rotatably engaged with the support 41. Each end of the rotating shaft 42 passing through the support 41 has a limiting disc 43, which contacts the two sides of the support 41 to axially limit the position of the rotating shaft 42. The flange is connected to the rotating shaft 42. Through the above arrangement, the rotating shaft 42 can be rotatably engaged with the support frame 1, and the axial direction of the rotating shaft 42 can be positioned to prevent axial displacement of the rotating shaft 42. Thus, during the test, the axial movement of the rotating head 5 is prevented.

[0044] Test procedure: The output shaft of the test motor transmits torque to the rotating head 5 through the reducer, thereby driving the rotating head 5 to rotate, simulating the situation where the wind drives the rotating head 5 to rotate during normal operation; by adjusting the speed of the output shaft of the test motor, the rotation of the rotating head 5 under different wind forces can be simulated; under different simulated wind forces, it is tested whether the adjustment structure inside the rotating head 5 can properly adjust the rotation angle of the drive shaft 55.

[0045] In some embodiments, such as Figures 1 to 8 As shown, the support component 2 includes a sliding seat 22 and an arc plate 23. The sliding seat 22 is laterally slidably disposed on the support frame 1. The sliding seat 22 has a power component 24 for lifting the arc plate 23. The roller 21 is disposed on the concave surface of the arc plate 23.

[0046] By dividing the support component 2 into two parts, the sliding seat 22 and the arc plate 23, the support component 2 can be moved laterally, and the arc plate 23 can be raised and lowered. When the support component 2 is moved laterally to a position away from the drive mechanism 3 and the support structure 4, it is the loading position. After the rotating head 5 is hoisted onto the arc plate 23 by the hoisting equipment, the subsequent process does not require the hoisting equipment to participate, thus avoiding the rotating head 5 being suspended in the air before installation.

[0047] In some embodiments, such as Figures 1 to 8As shown, one end of the arc plate 23 has an L-shaped plate 25 that is inserted into and cooperates with the positioning ring 53. A slot is formed between the L-shaped plate 25 and the end of the arc plate 23. The two sides of the slot respectively contact the two ends of the positioning ring 53 to axially limit the rotation of the machine head 5.

[0048] After the rotating head 5 is hoisted onto the arc plate 23, the outer peripheral wall of the second housing 52 contacts the roller 21, and the positioning ring 53 is engaged with the slot. At this time, the rotating head 5 can be axially positioned. That is, the axial positioning of the rotating head 5 can be completed by hoisting the rotating head 5 onto the arc plate 23, without the need for the operator to adjust the position of the rotating head 5 axially.

[0049] In some embodiments, such as Figures 1 to 8 As shown, the arc plate 23 has a relief groove 231 symmetrical about the arc surface at one end of the slot. When the arc plate 23 slides down to the position where it is separated from the rotating head 5, there is a gap between the relief groove 231 and the positioning ring 53.

[0050] By setting a clearance groove 231 on the arc plate 23, clearance can be achieved. After the rotating head 5 is installed on the drive mechanism 3 and the support structure 4, the arc plate 23 is reset downward. At this time, the roller 21 is separated from the second housing 52, the positioning ring 53 is separated from the slot, and there is a gap between the clearance groove 231 on the arc plate 23 and the positioning ring 53. Therefore, during the rotation of the rotating head 5, no friction will occur between the rotating head 5 and the arc plate 23, thus avoiding wear on the rotating head 5.

[0051] In some embodiments, such as Figures 1 to 8 As shown, the support frame 1 has a transverse slide rail 11, and the bottom of the sliding seat 22 has a slide groove 221 that mates with the transverse slide rail 11; a screw 12 is rotatably mounted on the support frame 1, and one end of the screw 12 is connected to the output shaft of the transverse drive motor 13; the sliding seat 22 has a threaded through hole that mates with the screw 12.

[0052] There are two transverse slide rails 11, which are located near the sides of the sliding seat 22. The screw 12 is located in the middle of the two transverse slide rails 11. The transverse drive motor 13 is fixed on the support frame 1. By driving the screw 12 to rotate through the transverse drive motor 13, the sliding seat 22 can slide along the transverse slide rails 11, allowing the sliding seat 22 to switch between the installation position and the feeding position.

[0053] In some embodiments, such as Figures 1 to 8 As shown, two positioning components 14 are connected to the transverse slide rail 11, and the length between the two positioning components 14 is the stroke of the slide seat 22; both positioning components 14 have through holes for rotating with the screw 12.

[0054] When the sliding seat 22 contacts the positioning component 14, the positioning component 14 limits the sliding seat 22; by setting two positioning components 14 on the transverse slide rail 11, the installation position and feeding position of the sliding seat 22 can be positioned.

[0055] A guide rod 15 is also connected between the two positioning components 14. There are two guide rods 15, which are symmetrically arranged about the screw 12. The sliding seat 22 has a through hole for sliding engagement with the guide rod 15.

[0056] In some embodiments, such as Figures 1 to 8 As shown, the sliding seat 22 has an internal accommodating cavity 222, and the power component 24 is disposed in the accommodating cavity 222; the bottom of the arc plate 23 has an insert 233, and the lifting end of the power component 24 is inserted into the insert 233; there are two sets of power components 24, and the two sets of power components 24 are symmetrically arranged about the axis of the arc plate 23; the top of the sliding seat 22 has an abutting surface that contacts the bottom of the arc plate 23, and when the sliding seat 22 slides down to the position where it is separated from the rotating head 5, the bottom of the rotating head 5 contacts the abutting surface of the sliding seat 22.

[0057] The power component 24 can be a pneumatic cylinder or a hydraulic cylinder. Taking a pneumatic cylinder as an example, the side wall of the sliding seat 22 has a through hole for the air pipe to pass through, and the air pipe is a flexible hose. When the sliding seat 22 is in the loading position, the rotating head 5 is hoisted onto the arc plate 23 by a hoisting device. Then the piston rod of the pneumatic cylinder extends and pushes the arc plate 23 upward so that the flange on the rotating head 5 is at the same height as the flange on the drive mechanism 3 and the flange on the support structure 4. Then the arc plate 23 drives the rotating head 5 to move laterally to the installation position. The flange alignment process is completed by rotating the rotating head 5, which makes it easier for the rotating head 5 to be installed on the drive mechanism 3 and the support structure 4.

[0058] In some embodiments, such as Figures 1 to 8 As shown, the concave surface of the arc plate 23 has a placement groove 232 for placing the roller 21. The placement groove 232 has insertion holes on both sides, one of which is connected to the end of the arc plate 23. The roller 21 has a through hole aligned with the insertion hole. When the roller 21 is located in the placement groove 232, the through hole of the roller 21 is aligned with the insertion hole. The rotating shaft is inserted into the insertion hole and the through hole of the roller 21 to make the roller 21 rotate around the rotating shaft.

[0059] When installing the roller 21, first place the roller 21 in the placement groove 232, and then insert the rotating shaft from the end of the arc plate 23. One end of the rotating shaft passes through the roller 21 and is inserted into the insertion hole on the other side of the placement groove 232. With the above arrangement, the roller 21 can be confined in the placement groove 232 and the roller 21 can be rotated around the rotating shaft.

[0060] For example, there are two rollers 21, which are symmetrically arranged about the axis of the arc plate 23; after the rollers 21 are installed, a part of the rollers 21 protrudes from the concave surface of the arc plate 23.

[0061] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
