Description

Technical Field

[0001] The present invention relates to the field of installation of circuit breaker fault detection devices, and in particular to an installation structure of a circuit breaker fault detection device for a wind turbine generator set. Background Art

[0002] The circuit breaker fault detection device plays a very critical role in the circuit. It can always detect whether the circuit breaker is working properly. If it cannot detect the circuit breaker, personnel will not be able to accurately and timely know the working status of the circuit breaker, which is not conducive to safe use of electricity. In the process of wind power generation, the power needs to be transformed before it can be transmitted to the power grid. A circuit breaker is set in the transformer, and a circuit breaker fault detection device is also set; Patent: CN216852652U provides a mounting structure for a circuit breaker fault detection device of a wind turbine generator set. The mounting structure for the circuit breaker fault detection device of a wind turbine generator set includes: a circuit breaker fault detection device, a fixing plate and four pins; the fixing plate is fixedly mounted on one side of the circuit breaker fault detection device, and the four pins are all mounted on the inner wall of one side of the transformer, and the four pins are distributed in a rectangular array, and the four pins all pass through the fixing plate and are slidably connected to the fixing plate. The mounting structure for the circuit breaker fault detection device of a wind turbine generator set provided by this technology is simpler and faster for the installation and disassembly of the circuit breaker fault detection device and the fixing plate than the traditional screw installation, which can save installation time, not only facilitate maintenance personnel, but also increase the working time of the transformer, and to a certain extent improve the utilization of wind power; The above technology requires that multiple pressure rods be controlled separately by multiple pressing plates to control the movement of multiple pressure rods, thereby controlling the plug block to retract into the first installation cavity, thereby realizing the separation of the fixing plate from the outside of the pin rod, and then realizing the disassembly of the fault detection device. This operation requires simultaneous control of the movement of multiple pressure rods to retract the plug block, which is inconvenient to operate and cannot effectively avoid the movement of multiple pressure rods caused by accidental touch, thereby causing the plug block to retract, thereby causing the fault detection device to fall. Improvement is needed. For this purpose, we propose an installation structure for a wind turbine generator circuit breaker fault detection device. Summary of the Invention

[0003] Purpose of the invention: The purpose of the present invention is to provide a device which optimizes the design of the operating structure, thereby achieving the control of the synchronous contraction of multiple plug-ins with only a single operation, simplifying the disassembly process of the fault detection device, and solving the problem of inconvenience in operation caused by the need to simultaneously control the activities of multiple pressure rods in the prior art; the present invention also adds a device to prevent the contraction of the plug-in caused by non-human operation or accidental touch, thereby preventing the fault detection device from falling due to accidental separation from the pin rod, and improving the safety and stability of the installation structure.

[0007] Furthermore, both sides of the lower support plate are symmetrically fixedly connected with rotating heads, and a support plate is connected between the two rotating heads facing each other through a rotating shaft. The bottom of the support plate is rotatably connected with a concave moving part through a rotating shaft, and the upper surface of the concave moving part is fixedly connected with an L-shaped connecting frame, and the inner side of the L-shaped connecting frame is located on the inner side of the circular toggle groove one and is fixedly connected with toggle column two.

[0008] Furthermore, a circular toggle groove three is formed on the lower surface of the toggle plate, an inclined toggle groove four is integrally formed at one end of the circular toggle groove three, and a circular toggle groove four is integrally formed at one end of the inclined toggle groove four away from the circular toggle groove three.

[0009] The cam is connected to the hydraulic box 1 on both sides of the upper surface of the mounting plate 1, and the upper surface of the mounting plate 1 is located in the front and rear of the hydraulic box 1 and is fixedly connected to the hydraulic box 2, and a through pipe is fixedly connected between the hydraulic box 1 and the hydraulic box 2, and the interior of the hydraulic box 1 is slidably connected to the piston block 1, and the end of the piston block 1 close to the toggle plate is fixedly connected to the connecting head 2, and the end of the connecting head 2 away from the piston block 1 passes through the outer side of the hydraulic box 1 and is fixedly connected to the toggle column 3, the top of the toggle column 3 extends to the inner side of the circular toggle groove 3 and is slidably connected to the circular toggle groove 3, the interior of the hydraulic box 2 is slidably connected to the piston block 2, and the side of the piston block 2 close to the hollow tube is fixedly connected to the rack, and the end of the rack away from the piston block 2 passes through the outer side of the hydraulic box 2 and is slidably connected to the hydraulic box 2, and the outer wall of the rack is slidably connected to the outer wall of the gear.

[0010] Furthermore, the inner side of the concave movable member is slidably connected to two guide rods, one end of the guide rod is fixedly connected to a fixed block, and the bottom of the fixed block is fixedly connected to the upper surface of the mounting plate.

[0013] Beneficial effects: With an integrated control structure centered on the dial, multiple transmission actions can be completed with a single press and turn operation: after pressing the dial to switch the height, the lower support plate is driven to descend and release the clamp, the rack transmission controls the synchronous contraction of the upper block, and the lower support plate is driven to ascend and assist in disengagement during the rotation process; Compared to the existing technology that requires the simultaneous control of multiple pressure rods, this design integrates the disassembly process into a single continuous operation, greatly simplifying the operation steps, reducing the operating difficulty for maintenance personnel, and significantly shortening the disassembly time of the fault detection device; The device effectively avoids accidental disengagement caused by non-human operation or mistaken touch through a multi-level structural design. Under normal conditions, the height difference between the bottom of the circular toggle groove 2 and the inclined toggle groove 2 forms a physical barrier to the toggle column 2. Even if the device is vibrated, the toggle column 2 cannot enter the circular toggle groove 2 to trigger subsequent transmission, thereby preventing the structure from loosening due to vibration. In the initial rotation of the toggle disk, the sliding stroke of the toggle column 2 along the circular toggle groove 1 is an "invalid operation range", which avoids the toggle disk rotation caused by slight mistaken touch and causing the device to loosen. The locking structure of the limit block and the upper block forms a forced operation sequence. The limit block must first be separated from the upper block by lowering the lower support plate before the upper block can be controlled to retract. From a mechanical principle, the problem of premature retraction of the upper block caused by mistaken operation is eliminated. Multiple designs jointly ensure the installation firmness of the detection device body in a non-maintenance state, completely solve the safety hazard of the fault detection device falling due to mistaken touch in the prior art, and significantly improve the safety and stability of the installation structure. The "press-turn" step-by-step disassembly process, coupled with the structural linkage, forms a clear logical chain: the lower pallet descends to release the clamp, the upper block retracts to remove the top obstruction, and the lower pallet rises to assist in disengagement. Each step is seamlessly connected by the dial's rotational travel, eliminating the need for additional tools or complex judgment. Furthermore, the structural design ensures precise linkage between components, avoiding the risk of operational stalls or failures. This not only facilitates maintenance personnel in completing disassembly and assembly tasks quickly, but also ensures operational reliability through the deterministic mechanical structure.

[0016] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] Example like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, a mounting structure for a wind turbine generator circuit breaker fault detection device is provided, comprising a mounting plate 1, a plurality of hollow tubes 2 being fixedly connected to the upper surface of the mounting plate 1, a mounting plate 2 3 being slidably connected to the outer side walls of the plurality of hollow tubes 2, and a detection device body 4 being fixedly mounted to the upper surface of the mounting plate 2 3; A notch 5 is provided below the outer wall of the hollow tube 2. A rotating rod 6 is rotatably connected to the inner lower surface of the hollow tube 2 through a rotating shaft. A gear 7 is fixedly connected to the outer wall of the rotating rod 6 and located inside the notch 5. An inclined toggle groove 8 is symmetrically provided on the upper surface of the rotating rod 6. A toggle column 9 is slidably connected to the inner side of the inclined toggle groove 8. A connector 10 is fixedly connected to the top of the toggle column 9. An upper stopper 11 is fixedly connected to the end of the connector 10 away from the toggle column 9. The end of the upper stopper 11 away from the connector 10 passes through the outer side of the hollow tube 2 and is slidably connected to the hollow tube 2. The lower surface of the upper stopper 11 fits into the upper surface of the mounting plate 2 3. A damping plate 12 is fixedly mounted on the upper surface of the mounting plate 1 between the multiple hollow tubes 2. Multiple damping springs 13 are fixedly connected to the upper surface of the damping plate 12. The top ends of the multiple damping springs 13 are fixedly connected to a lower supporting plate 14. The upper surface of the lower supporting plate 14 is in contact with the lower surface of the mounting plate 2 3. Threaded posts 15 are provided at the four corners of the mounting plate 1; The mounting plate 1 is fixed to the inner wall of the transformer by a threaded column 15; in this arrangement, the gear 7 is driven to rotate by an external force, which can drive the rotating rod 6 to rotate around the rotating shaft. When the rotating rod 6 rotates, the inclined toggle groove 8 on its surface will slide relative to the toggle column 9, and the guiding effect of the inclined toggle groove 8 will push the connector 10 to move, thereby controlling the two upper blocks 11 to synchronously retract toward the inside of the hollow tube 2 or extend outward; when it is necessary to disassemble the detection device body 4, after controlling the upper block 11 to retract into the inside of the hollow tube 2, the mounting plate 2 3 can slide freely along the outer wall of the hollow tube 2, which is convenient for removing from the outside of the hollow tube 2 Disengagement enables rapid disassembly of the detection device body 4; when the detection device body 4 is installed on the outside of multiple hollow tubes 2 through the mounting plate 2 3, the upper stopper 11 is controlled to extend from the outside of the hollow tube 2. At this time, multiple shock-absorbing springs 13 generate an upward thrust due to elastic potential energy, pushing the lower support plate 14 to squeeze the mounting plate 2 3 upward, so that the mounting plate 2 3 is tightly fitted to the lower surface of the upper stopper 11, thereby achieving a firm installation of the mounting plate 2 3; at the same time, the mounting plate 2 3 can slide slightly along the outer wall of the hollow tube 2, and with the elastic buffering effect of the shock-absorbing spring 13, it can effectively absorb external vibrations and play a shock-absorbing and buffering effect.

[0018] like Figure 2 and Figure 5 As shown, both sides of the lower support plate 14 are symmetrically fixedly connected with rotating heads 25, and a support plate 26 is connected to the two rotating heads 25 facing each other through a rotating shaft. The bottom of the support plate 26 is rotatably connected to a concave moving member 27 through a rotating shaft. The upper surface of the concave moving member 27 is fixedly connected to an L-shaped connecting frame 28. The inner side of the L-shaped connecting frame 28 is located inside the circular toggle groove 1 21 and is fixedly connected to a toggle column 29. The inner side of the concave moving member 27 is slidably connected to two guide rods 41, one end of the guide rod 41 is fixedly connected to a fixed block 42, and the bottom of the fixed block 42 is fixedly connected to the upper surface of the mounting plate 1; When the device is subjected to external vibration, the lower support plate 14 will move downward with the vibration, and the supporting plate 26 will be driven to rotate around the rotating axis through the rotating head 25. During the rotation of the supporting plate 26, the concave moving part 27 is pushed to slide slightly along the outer wall of the guide rod 41. The sliding cooperation between the concave moving part 27 and the guide rod 41 and the rotation buffering of the support plate 26 are utilized to further enhance the shock absorbing and buffering effect of the device and reduce the impact of vibration on the detection device body 4.

[0019] like Figure 2 、 Figure 6 、 Figure 7 and Figure 8As shown, a mounting box 16 is embedded in the interior of the mounting plate 1, and a lifting plate 17 is slidably connected to the interior of the mounting box 16. A plurality of extrusion springs 18 are fixedly connected between the lifting plate 17 and the mounting box 16. The upper surface of the lifting plate 17 is symmetrically rotatably connected to a round rod 19 through a rotating axis. The top of the round rod 19 passes through the top of the mounting plate 1 and is fixedly connected to a toggle plate 20. A circular toggle groove 1 21 is provided on the upper surface of the toggle plate 20. An inclined toggle groove 2 22 is integrally formed at one end of the inner portion of the circular toggle groove 1 21. A circular toggle groove 2 23 is integrally formed at one end of the inclined toggle groove 22 away from the circular toggle groove 1 21. An inclined toggle groove 3 24 is integrally formed at one end of the circular toggle groove 23 away from the inclined toggle groove 22. A circular toggle groove 30 is formed on the lower surface of the toggle plate 20. An inclined toggle groove 4 31 is integrally formed at one end of the circular toggle groove 30. A circular toggle groove 4 32 is integrally formed at the end of the inclined toggle groove 4 31 away from the circular toggle groove 30. The inner lower surface of the second circular toggle groove 23 and the inner lower surface of the third inclined toggle groove 24 are on the same horizontal plane, and are both higher than the inner lower surface of the second inclined toggle groove 22 and the inner lower surface of the first circular toggle groove 21. The inner lower surface of the second inclined toggle groove 22 and the inner lower surface of the first circular toggle groove 21 are on the same horizontal plane. Both sides of the upper surface of the mounting plate 1 are fixedly connected to the hydraulic box 1 33, and the upper surface of the mounting plate 1 is fixedly connected to the hydraulic box 2 34 in front and behind the hydraulic box 1 33. A through pipe 35 is fixedly connected between the hydraulic box 1 33 and the hydraulic box 2 34. The interior of the hydraulic box 1 33 is slidably connected to the piston block 1 36. The end of the piston block 1 36 close to the dial plate 20 is fixedly connected to the connector 2 37. The end of the connector 2 37 away from the piston block 1 36 passes through the outer surface of the hydraulic box 1 33. The top of the toggle column 38 extends to the inner side of the circular toggle groove 30 and is slidably connected to the circular toggle groove 30. The interior of the hydraulic box 2 34 is slidably connected to the piston block 2 39. The side of the piston block 2 39 close to the hollow tube 2 is fixedly connected to the rack 40. The end of the rack 40 away from the piston block 2 39 extends to the outside of the hydraulic box 2 34 and is slidably connected to the hydraulic box 2 34. The outer wall of the rack 40 is slidably connected to the outer wall of the gear 7. The circular toggle groove 1 21, the circular toggle groove 23, the circular toggle groove 30, and the circular toggle groove 4 32 are all small segments of circular ring-shaped grooves; wherein, the diameter of the circular toggle groove 1 21 is larger than the diameter of the circular toggle groove 23, and the diameter of the circular toggle groove 30 is smaller than the diameter of the circular toggle groove 4 32; the inclined toggle groove 2 22 gradually tilts toward the center of the toggle disk 20 as it extends from the circular toggle groove 1 21 to the circular toggle groove 2 23; the inclined toggle groove 3 24 gradually tilts toward the outside of the toggle disk 20 as it extends outward from the circular toggle groove 23; and the inclined toggle groove 4 31 gradually tilts toward the outside of the toggle disk 20 as it extends from the circular toggle groove 30 to the circular toggle groove 4 32. Under normal conditions, the extrusion spring 18 is in a slightly compressed state, pushing the lifting plate 17 upward to keep the toggle plate 20 in the raised position. At this time, the bottom end of the second toggle column 29 is in contact with the inner lower surface of the circular toggle groove 1 21. When the device is subjected to vibration, the lower support plate 14 descends and drives the second toggle column 29 to move through the transmission structure. At this time, the second toggle column 29 will slide along the circular toggle groove 1 21 into the inclined toggle groove 22. Due to the bottom height difference between the circular toggle groove 23 and the inclined toggle groove 22, the circular toggle groove 23 will block the second toggle column 29, preventing it from continuing to slide into the circular toggle groove 23, thereby preventing the vibration from triggering subsequent structural transmission and ensuring the stability of the device installation. When it is necessary to remove the mounting plate 2 3 and the detection device body 4, the toggle plate 20 is first pressed downward to compress the extrusion spring 18 and drive the lifting plate 17 to descend until the bottom of the toggle post 29 is flush with the inner lower surface of the circular toggle groove 23 and the inclined toggle groove 3 24, and at this time the toggle post 29 has not disengaged from the circular toggle groove 1 21 and the inclined toggle groove 2 22; then the toggle plate 20 is rotated, and the toggle post 29 will initially slide along the inner side of the circular toggle groove 1 21, and will not pull the lower support plate 14 down at this stage. This section of travel is the rotation buffer zone of the toggle plate 20, which can effectively avoid the toggle plate 20 from rotating due to accidental touch and prevent the device from loosening; As the toggle plate 20 continues to rotate, the second toggle post 29 slides into the inner side of the second tilt toggle slot 22. Under the guidance of the second tilt toggle slot 22, the two second toggle posts 29 move in opposite directions, pulling the concave moving member 27 through the L-shaped connecting frame 28, thereby driving the support plate 26 to rotate, causing the lower support plate 14 to descend, releasing the squeeze clamping on the lower side of the second mounting plate 3; During the sliding process of the toggle column 29 along the circular toggle groove 1 21 and the inclined toggle groove 2 22, the toggle column 3 38 slides synchronously along the inner side of the circular toggle groove 3 30, and at this stage, it does not push the piston block 1 36 to move; when the toggle column 29 slides to the inner side of the circular toggle groove 2 23, the toggle column 38 will enter the inner side of the inclined toggle groove 4 31, and under the pushing action of the inclined toggle groove 4 31, the connector 2 37 drives the piston block 1 36 to slide inside the hydraulic box 1 33, and pressurizes the inside of the hydraulic box 2 34 through the through pipe 35, pushing the piston block 2 39 to move, thereby causing the rack 40 to move toward the gear 7, and the rack 40 meshes with the gear 7 for transmission, driving the rotating rod 6 to rotate, causing the upper block 11 to shrink to the inner side of the hollow tube 2, thereby releasing the upper block 11 from blocking the top of the mounting plate 2 3; Continue to rotate the toggle disk 20. When the toggle column 29 rotates to the inner side of the inclined toggle groove 3 24, the toggle column 3 38 will slide into the inner side of the circular toggle groove 4 32. At this time, the rack 40 remains stationary and the upper block 11 maintains a retracted state. At the same time, the toggle column 29, under the squeezing action of the inclined toggle groove 3 24, pushes the two concave moving parts 27 to move in relative directions, and drives the lower support plate 14 to rise through the support plate 26. The lower support plate 14 pushes the mounting plate 2 3 upward, and the auxiliary mounting plate 2 3 is separated from the inner side of the hollow tube 2 to complete the disassembly.

[0020] like Figure 9 As shown, the upper stopper 11 is a concave structure with an open lower surface, and the upper surface of the mounting plate 2 3 is located inside the upper stopper 11 and a limit block 43 is provided; The upper block 11 is a concave structure with an open lower surface, and a limit block 43 is fixedly provided on the upper surface of the mounting plate 23 at the inner position of the upper block 11; when the mounting plate 23 is subjected to the upward extrusion thrust of the lower support plate 14, the limit block 43 will be engaged with the inner side of the upper block 11, and the upper block 11 is restricted from shrinking toward the inner side of the hollow tube 2 through the mechanical limit action; this structural design requires that when the device is disassembled, the lower support plate 14 must be controlled to descend first, so that the mounting plate 23 descends under its own gravity, driving the limit block 43 to detach from the inner side of the upper block 11, and then the upper block 11 can be controlled to shrink, thereby ensuring the sequentiality of the disassembly operation and further improving the installation stability of the device.

[0021] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
