[0033] Example 1

[0034] Reference Figure 1 , provides a schematic diagram of the overall structure of a blade damage degree monitoring device, such as Figure 1 A blade damage degree monitoring device includes a driving track mechanism 100, including a track portion 101, a driving portion 102 arranged in the track portion 101, and a sliding locking portion 103 connected to the driving portion 102; the driving portion 102 can drive the sliding locking portion 103 to move inside the track portion 101, a monitoring mechanism 200, used to monitor the state of the blade, the monitoring mechanism 200 is a device using the monitoring method recorded in the Chinese patent document with application number CN201410328876.9, and a connecting mechanism 300, a connecting column group 301 arranged on the monitoring mechanism 200, and a driving block 300 slidingly arranged on the connecting column group 301 02. The connecting mechanism 300 can connect the monitoring mechanism 200 and the driving track mechanism 100; the monitoring mechanism 200 is connected to the sliding locking portion 103 through the connecting mechanism 300. When the sliding locking portion 103 moves on the track portion 101, it drives the monitoring mechanism 200 to move along the track portion 101, wherein the track portion 101 is vertically installed on the main beam X of the power-generating wind turbine. When the sliding locking portion 103 moves up and down along the track portion 101, it can drive the monitoring mechanism 200 to move up and down along the main beam X. When the monitoring mechanism 200 reaches the monitoring position, the sliding locking portion 103 can be locked with the track portion 101, so that the position of the monitoring mechanism 200 is fixed.

[0035] Specifically, a limiting inner rail 101a is provided on the inner side of the track portion 101, and a limiting plate 101b and a locking plate 101c are provided on the side wall of the track portion 101; the driving portion 102 includes a rotating wheel group 102a provided on the inner side of the track portion 101, and a transmission belt 102b provided on the rotating wheel group 102a; the sliding locking portion 103 includes a sliding block 103a which is provided on the inner side of the limiting inner rail 101a and can slide, and a locking assembly 104 provided on the sliding block 103a; both ends of the transmission belt 102b are connected to the sliding block 103a, and the locking assembly 104 can be engaged with the locking plate 101c.

[0036] Among them, there are two limiting inner rails 101a, which are parallel to the main body of the track part 101. Contact wheels are provided on both sides of the sliding block 103a, and the contact wheels can roll. Through the forward and reverse rotation of the rotating wheel group 102a, the sliding block 103a can be driven to rise and fall under the guidance of the limiting inner rail 101a. When the monitoring mechanism 200 is driven to the monitoring position, the locking assembly 104 can be engaged with the locking plate 101c to preliminarily fix the position of the sliding block 103a and the monitoring mechanism.

[0037] Furthermore, the rotating wheel group 102a includes a driving wheel 102a-1 and a driven wheel 102a-2 respectively arranged at both ends of the track portion 101, and a locking box arranged on the driving wheel 102a-1, wherein the driving wheel 102a-1 is arranged at the bottom end of the track portion 101, and the driven wheel 102a-2 is located at the top end of the track portion 101. The driven wheel 102a-2 and the driving wheel 102a-1 can both adopt sprockets, and the transmission belt 102b can select a chain belt. At the same time, the driven wheel 102a-2 and the driving wheel 102a-1 can be belt gears 404b-1, and the transmission belt 102b can be a toothed belt.

[0038] Among them, the position of the locking box corresponds to the position of the driving wheel 102a-1, and a plurality of positioning holes are opened on the driving wheel 102a-1. The locking box is fixed on the track part 101, and it has a threaded pin (102f). When the driving wheel 102a-1 rotates, a plurality of positioning holes circulate through the threaded pin (102f). When the position of the sliding block 103a and the monitoring mechanism 200 is locked, the threaded pin (102f) can be inserted into the inner side of the positioning hole, thereby achieving the positioning effect of the driving wheel 102a-1 and assisting the positioning of the monitoring mechanism 200.

[0039] Operation process: The driving part 102 can drive the sliding locking part 103 to move on the inner side of the track part 101, and the monitoring mechanism 200 is connected to the sliding locking part 103 through the connecting mechanism 300. When the sliding locking part 103 moves on the track part 101, it drives the monitoring mechanism 200 to move along the track part 101. The track part 101 is vertically installed on the main beam X of the power generation wind turbine. When the sliding locking part 103 moves up and down along the track part 101, it can drive the monitoring mechanism 200 to move up and down along the main beam X. When the monitoring mechanism 200 reaches the monitoring position, the sliding locking part 103 can be locked with the track part 101, so that the position of the monitoring mechanism 200 is fixed.

[0040] Example 2

[0041] Reference Figure 2 , this embodiment is different from the first embodiment in that: the connecting column group 301 includes a connecting block 301a arranged on the monitoring mechanism 200, a vertical column 301b arranged on the connecting block 301a, and a first spring 301c sleeved on the vertical column 301b; the driving block 302 is sleeved on the outer side of the vertical column 301b, and the driving block 302 is connected to the sliding block 103a. A stop plate 201 is fixed on the monitoring mechanism 200. When the monitoring mechanism 200 reaches the monitoring position, the stop plate 201 contacts the limit plate 101b. The limit plate 101b prevents the monitored mechanism 200 from continuing to move upward by resisting the stop plate 201. At this time, the monitoring mechanism 200 continues to move upward. The positively rotating driving wheel 102a-1 can drive the sliding block 103a to continue to move upward along the vertical column 301b. At this time, the driving block 302 squeezes the first spring 301c until the position of the locking component 104 on the sliding block 103a corresponds to the position of the locking plate 101c. At this time, the locking component 104 and the locking plate 101c are locked, fixing the position of the sliding block 103a and the driving block 302. The thrust of the first spring 301c acts on the connecting block 301a, thereby being transmitted to the monitoring mechanism 200, and pressing the stop plate 201 on the monitoring mechanism 200 against the limit plate 101b, thereby stabilizing the position of the monitoring mechanism 200.

[0042] A first groove 103a-1 and a second groove 103a-2 are respectively provided on both sides of the sliding block 103a, and an inner groove 103a-3 is provided in the first groove 103a-1 of the sliding block 103a; wherein, the first groove 103a-1 and the second groove 103a-2 are positioned correspondingly, the inner groove 103a-3 is connected to the first groove 103a-1, and a bottom through hole penetrating to the bottom of the sliding block 103a is provided at the bottom of the inner groove 103a-3. In this embodiment, the number of locking components 104 is two.

[0043] The locking assembly 104 includes an elastic locking member 104a and a pull unlocking member 104b;

[0044] Among them, the elastic locking member 104a includes a movable column 104a-1 that slides through the sliding block 103a, a locking head 104a-2 located at one end of the movable column 104a-1, a pressure block 104a-3 located at the other end of the movable column 104a-1, and a second spring 104a-4 that is sleeved on the outer side of the movable column 104a-1 and contacts the pressure block 104a-3; in the natural state, the unlocking member 104b is pulled to contact the elastic locking member 104a, the locking head 104a-2 extends to the outer side of the second groove 103a-2, one end of the movable column 104a-1 extends to the inner side of the first groove 103a-1, and the other end extends to the inner side of the second groove 103a-2, the installed end of the locking head 104a-2 corresponds to the position of the second groove 103a-2, and the installed end of the pressure block 104a-3 corresponds to the position of the first groove 103a-1.

[0045] In the natural state, the unlocking member 104b is pulled to resist the pressure block 104a-3, so that the lock head 104a-2 extends from the inner side of the first groove 103a-1. The upper surface of the lock head 104a-2 is the outer cylindrical surface S1, and the lower surface of the lock head 104a-2 is the locking plane S2. When the lock head 104a-2 follows the sliding block 103a to reach the corresponding position of the locking plate 101c, the lock head 104a-2 continues to rise with the sliding block 103a, and its outer cylindrical surface S1 will be squeezed by the locking plate 101c. At this time, the lock head 104a-2 applies a thrust to the movable column 104a-1 in the direction of the first groove 103a-1, and the movable column 104a-1 drives the lock head 104a-2 to move. 04a-2 retracts to the inner side of the second groove 103a-2. When the position of the lock head 104a-2 corresponds to the position of the locking hole 101c-1, the pressing force of the locking plate 101c on the lock head 104a-2 disappears. Under the push of the unlocking piece 104b pulled by the pressure block 104a-3, the movable column 104a-1 pushes the lock head 104a-2 into the inner side of the locking hole 101c-1. At this point, the locking plane S2 of the lock head 104a-2 and the bottom surface of the locking hole 101c-1 remain in a state of resistance under the push of the first spring 301c, and cannot be detached from the inner side of the locking hole 101c-1, thereby achieving the effect of locking the position of the sliding block 103a and the monitoring mechanism 200.

[0046] The pull-unlocking member 104b includes an inner column 104b-1 slidably arranged on the sliding block 103a, a resistance block 104b-2 arranged at one end of the inner column 104b-1 and in contact with the pressure block 104a-3, an extrusion ring 104b-3 sleeved on the outer side of the inner column 104b-1, a third spring 104b-4 in contact with the extrusion ring 104b-3, and a connecting plate 104b-5 located at the end of the inner column 104b-1 away from the resistance block 104b-2; one end of the transmission belt 102b is connected to the connecting plate 104b-5; a locking hole 101c-1 is opened on the locking plate 101c.

[0047] Among them, the inner column 104b-1 slides through the bottom through hole, and a spring hole is opened in the bottom through hole. The position of the extrusion ring 104b-3 is located inside the spring hole. The third spring 104b-4 is sleeved on the outside of the inner column 104b-1, and is located below the extrusion ring 104b-3. It keeps the state of resisting the extrusion ring 104b-3 in the natural state. When maintenance is required, the driving wheel 102a-1 is reversed, and the driving wheel 102a-1 drives the transmission belt 102b to reverse. At this time, the end of the transmission belt 102b connected to the connecting plate 104b-5 pulls the connecting plate 104b-5 downward, and the connecting plate 104b-5 pulls the inner column 104b downward. -1, the inner column 104b-1 drives the extrusion ring 104b-3 to press the third spring 104b-4, and at the same time drives the resistance block 104b-2 to move downward, and the resistance block 104b-2 enters the inner side of the inner groove 103a-3. At this time, the force-bearing block is no longer subjected to the pressure of the resistance block 104b-2. Under the push of the second spring 104a-4, the second spring 104a-4 pushes the force-bearing block, so that the force-bearing block drives the movable column 104a-1, and drives the lock head 104a-2 to move into the second groove 103a-2. When the lock head 104a-2 enters the inner side of the second groove 103a-2, the sliding block 103a is unlocked.

[0048] The upper surface of the resisting block 104b-2 is an extrusion slope, which is used to contact the pressure-bearing block 104a-3. The resisting block 104b-2 is in the shape of a right-angled trapezoid as a whole.

[0049] The rest of the structure is the same as that of Example 1.

[0050] Operation process: When the lock head 104a-2 follows the sliding block 103a to the corresponding position of the locking plate 101c, the lock head 104a-2 continues to rise with the sliding block 103a, and its outer cylindrical surface S1 is squeezed by the locking plate 101c. At this time, the lock head 104a-2 applies a thrust to the movable column 104a-1 in the direction of the first groove 103a-1, and the movable column 104a-1 drives the lock head 104a-2 to retract to the second groove 103a-2. When the position of the lock head 104a-2 corresponds to the position of the locking hole 101c-1, the pressing force of the locking plate 101c on the lock head 104a-2 disappears, and the pressure block 104a-3 is pushed by the unlocking piece 104b, and the movable column 104a-1 pushes the lock head 104a-2 to enter the inner side of the locking hole 101c-1. At this point, the locking plane S2 of the lock head 104a-2 and the bottom surface of the locking hole 101c-1 remain in a state of resistance under the push of the first spring 301c, and cannot be detached from the inner side of the locking hole 101c-1, thereby achieving the effect of locking the position of the sliding block 103a and the monitoring mechanism 200.

[0051] When maintenance is required, the driving wheel 102a-1 is reversed, and the driving wheel 102a-1 drives the transmission belt 102b to reverse. At this time, the end of the transmission belt 102b connected to the connecting plate 104b-5 pulls the connecting plate 104b-5 downward, and the connecting plate 104b-5 pulls the inner column 104b-1 downward. The inner column 104b-1 drives the extrusion ring 104b-3 to press the third spring 104b-4, and at the same time drives the resistance block 104b-2 to move downward, and the resistance block 104b-2 enters the inner groove 103 a-3, at this time, the force-bearing block is no longer subjected to the pressure of the resistance block 104b-2, and under the push of the second spring 104a-4, the second spring 104a-4 pushes the force-bearing block, so that the force-bearing block drives the movable column 104a-1, and drives the lock head 104a-2 to move toward the inside of the second groove 103a-2. When the lock head 104a-2 enters the inner side of the second groove 103a-2, the sliding block 103a is unlocked, and the monitoring mechanism 200 can be lowered from a high place through the sliding block 103a.

[0053] Reference Figure 2 , this embodiment is different from the above embodiments in that: it also includes a stabilizing mechanism 400, which includes a lifting portion 401, which connects the driving block 302 and the monitoring mechanism 200; an adjusting portion 402, which is connected to the lifting portion 401; a transposition portion 403, which is located at the back of the monitoring mechanism 200; a rotating pin portion 404, which is arranged on the transposition portion 403; wherein the lifting portion 401 can drive the adjusting portion 402 to adjust the position of the transposition portion 403, thereby driving the rotating pin portion 404 to switch between the locking position and the buffering position; a buffering gear rod 101d and a positioning buckle 101e are provided on the track portion 101, when the rotating pin portion 404 is in the locking position, it can enter the inner side of the positioning buckle 101e, and when the rotating pin portion 404 is in the buffering position, it can conflict with the buffering gear rod 101d, and when the sliding block 103a passes through the locking assembly 104 and the locking plate 101 c When locked, the rotating pin portion 404 will reach the locking position driven by the shifting portion 403. At this time, the rotating pin portion 404 enters the inner side of the positioning buckle 101e, further stabilizing the position of the monitoring mechanism 200. When the sliding block 103a slides downward, the rotating pin portion 404 will reach the buffer position driven by the shifting portion 403. At this time, the rotating pin portion 404 and the buffering gear rod 101d are in conflict with each other, and when the sliding block 103a drives the monitoring mechanism 200 to descend, it generates damping to avoid damage to the monitoring mechanism 200 caused by excessive descent speed.

[0054] Specifically, the lifting part 401 includes a back rail 401a, which is arranged on the monitoring mechanism 200, on which a sliding rail 401a-1 is provided, and side through grooves 401a-2 are opened on both sides of the sliding rail 401a-1; an inner sliding component 401b, a sliding body 401b-1 slidably arranged on the inner side of the sliding rail 401a-1, side guide protrusions 401b-2 located on both sides of the sliding body 401b-1, and an extension block 401b-3 fixed on the sliding body 401b-1; an elastic connecting component 401c, including a frame 401c-1 fixed on the driving block 302, a through column 401c-2 fixed on the frame 401c-1 and penetrating the extension block 401b-3, and an outer column spring 301c which is sleeved on the outer side of the through column 401c-2 and contacts the extension block 401b-3.

[0055] When the stop plate 201 and the limit plate 101b are in contact, the monitoring mechanism 200 cannot continue to move upward. At this time, the driving block 302 continues to move upward with the sliding block 103a, driving the frame 401c-1 to continue to move upward. The frame 401c-1 drives the column outer spring 301c to move upward. The column outer spring 301c pushes the extension block 401b-3 upward. The extension block 401b-3 drives the sliding body 401b-1 and the guide protrusion upward.

[0056] Furthermore, the adjustment part 402 includes a fixed axis 402a, which is fixed on the sliding body 401b-1; a swing arm member, which has a side extension section 402b-1 rotatably connected to the fixed axis 402a, and a contact section 402b-2 inclined to the side extension section 402b-1, and the number of the swing arm members is two; a rebound member, which includes two force buckles 402c-1 respectively arranged on the two side extension sections 402b-1, an arc column 402c-2 simultaneously penetrating the two force buckles 402c-1, a fourth spring 402c-3 sleeved on the outer side of the arc column 402c-2, and a limiting ring 402c-4 located at both ends of the arc column 402c-2; the two ends of the fourth spring 402c-3 respectively contact with the two force buckles 402c-1, and the limiting ring 402c-4 is in close contact with the force buckle 402c-1.

[0057] Among them, the installation position of the fixed shaft 402a corresponds to the position of the slide rail 401a-1. When the sliding body 401b-1 moves upward, it drives the fixed shaft 402a to move upward. At this time, the fixed shaft 402a drives the two swing arm members to move upward. In the natural state, the two swing arm members are pushed by the fourth spring 402c-3, and the two side extensions 402b-1 have an angle of 60 degrees to 120 degrees. When the fixed shaft 402a brings the two swing arm members into the slide rail 401a-1, the two sides of the slide rail 401a-1 respectively contact the two side extensions 402b-1, so that the two side extensions 402b-1 rotate close to each other.

[0058] The arc column 402c-2 is circular with the fixed axis 402a. When the two swing arms rotate close to each other, the force buckles 402c-1 on the two move closer to each other along the arc column 402c-2, squeezing the fourth spring 402c-3 between the two. During this process, the contact section 402b-2 can rotate with the side extension section 402b-1. At this time, the side extension section 402b-1 rotates to disengage from the transposition part 403, and the transposition part 403 drives the rotating pin part 404 to reach the locking position.

[0059] Moreover, when the sliding block 103a needs to descend, the sliding block 103a is unlocked, and the elastic force of the first spring 301c pushes the sliding block 103a and the driving block 302 to move downward. At this time, the sliding body 401b-1 moves downward when the outer spring 301c pushes the extension block 401b-3. The sliding body 401b-1 pushes the fixed axis 402a to move downward, and the two swing arm members detach from the inner side of the slide rail 401a-1. The elastic force of the fourth spring 402c-3 pushes the two swing arm members to rotate and unfold. During this process, the contact section 402b-2 rotates and pulls the transposition part 403, so that the transposition part 403 adjusts the rotating pin part 404 to the buffer position, unlocking the monitoring mechanism 200 while preparing the rotating pin part 404 for buffering.

[0060] The shifting portion 403 includes a side rail 403a disposed on the monitoring mechanism 200 and located on the back rail 401a; the elastic member 403b includes a cylinder 403b-1 fixed to the inner side of the side rail 403a, and a fifth spring 403b-2 sleeved on the outer side of the cylinder 403b-1; the sleeve rod component 403c includes a rod body 403c-1 slidably sleeved on the outer side of the cylinder 403b-1, and a protruding buckle 403c-2 fixed on the rod body 403c-1 and extending to the outer side of the side rail 403a.

[0061] In the natural state, the two swing arm members are in the unfolded state. At this time, the elastic force of the fourth spring 402c-3 pushes the side extension sections 402b-1 of the two swing arm members, so that the contact section 402b-2 can pull the protruding buckle toward the slide rail 401a-1, so that the rod body 403c-1 keeps pressing the fifth spring 403b-2. At this time, the position of the rotating pin part 404 corresponds to the position of the buffer gear rod 101d, reaching the buffer position.

[0062] When the swing arm begins to enter the slide rail 401a-1, the swing arm rotates, and the contact section 402b-2 in the swing arm slowly unfolds. At this time, the elastic force of the fifth spring 403b-2 can push the rod body 403c-1 to move away from the slide rail 401a-1 on the outside of the cylinder 403b-1 until the rotating pin part 404 enters the inner side of the positioning buckle 101e and reaches the locking position.

[0063] At the same time, it needs to be further explained that when the stop plate 201 and the limiting plate 101b are in contact, the position of the rotating pin portion 404 corresponds to the position of the positioning buckle 101e.

[0064] The rotating pin portion 404 includes an end shaft 404a, which is fixed on the rod body 403c-1; a rotating sleeve 404b, including a gear 404b-1 rotatably sleeved on the end shaft 404a, and a shell 404b-2 fixed on the gear 404b-1; a dual-purpose pin 404c, including a sixth spring 404c-1 located on the inner side of the shell 404b-2, a pin column 404c-2 that contacts the sixth spring 404c-1, and a locking pin head 404c-3 located at the end of the pin column 404c-2; a positioning gear rod 403a-1 is provided on the side rail 403a.

[0065] Among them, the gear 404b-1 can rotate on the outside of the end shaft 404a, but cannot move. When the gear 404b-1 rotates, it can drive the shell 404b-2 to rotate. The pin 404c-2 can move relative to the shell 404b-2, but cannot rotate. A limiting slot is opened at one end of the shell 404b-2 away from the gear 404b-1. One end of the pin 404c-2 extends to the inside of the shell 404b-2 through the limiting slot and contacts the sixth spring 404c-1. The lock pin head 404c-3 is located at the end of the pin 404c-2 located on the outside of the shell 404b-2.

[0066] The locking pin head 404c-3 has four side surfaces, two of which are opposite to each other and are arc-shaped pressure surfaces S3, and the other two are positioning planes S4. When in the buffer position, the two arc-shaped pressure surfaces S3 are facing upward and downward respectively. When pushed from the buffer position to the positioning surface, the middle section of the gear 404b-1 contacts the positioning gear rod 403a-1. Through the setting of the teeth of the positioning gear rod 403a-1 and the teeth of the gear 404b-1, the locking pin head 404c-3 rotates 90 degrees at this time, and the two positioning planes S4 face upward and downward respectively. The positioning buckle 101e has two inner surfaces S5 parallel to each other. After the locking pin head 404c-3 rotates 90 degrees, it continues to slide until it enters the inner side of the positioning buckle 101e. At this time, the rod body 403c-1 is pressed against the end of the cylinder 403b-1 by the fifth spring 403b-2, and the two positioning planes S4 and the two inner surfaces S5 fit together to reach a locked state.

[0067] When the locking pin head 404c-3 is in the buffer position and the sliding block 103a drives the monitoring mechanism 200 to move downward, the arc-shaped pressure surface S3 of the locking pin head 404c-3 will contact the teeth of the buffer tooth rod 101d. At this time, the teeth will resist the arc-shaped pressure surface S3, and the locking pin head 404c-3 will receive the resistance and transmit it to the monitoring mechanism 200. At the same time, under the push of the resistance, the locking pin head 404c-3 pushes the pin column 404c-2 toward the inner side of the shell 404b-2, pressing the sixth spring 404c-1. After disengaging from the teeth, the sixth spring 404c-1 pushes the pin column 404c-2 to reset. During this descending process, it can continuously generate resistance to the monitoring mechanism 200 to prevent the monitoring mechanism 200 from descending too fast.

[0068] The rest of the structure is the same as that of Example 2.

[0069] Operation process: when the rotating pin portion 404 is in the buffer position, it can conflict with the buffer tooth rod 101d. When the sliding block 103a is locked by the locking assembly 104 and the locking plate 101c, the rotating pin portion 404 will reach the locking position driven by the shifting portion 403. At this time, the rotating pin portion 404 enters the inner side of the positioning buckle 101e, further stabilizing the position of the monitoring mechanism 200. When the sliding block 103a slides downward, the rotating pin portion 404 will reach the buffer position driven by the shifting portion 403. At this time, the rotating pin portion 404 conflicts with the buffer tooth rod 101d, and when the sliding block 103a drives the monitoring mechanism 200 to descend, it generates damping to avoid damage to the monitoring mechanism 200 caused by excessive descent speed.
