Description

Technical Field

[0001] This utility model belongs to the field of safety mechanism technology, and in particular relates to a live induction warning device for a wind turbine generator converter. Background Technology

[0002] The converter is an important component of the wind turbine generator system. It is an electrical device that changes the voltage, frequency, number of phases, and other electrical quantities or characteristics of the power system. To ensure the safe use of the converter, it is usually installed in the converter cabinet.

[0003] According to a public disclosure (publication number: CN216922374U), a live-line induction warning device for a wind turbine generator converter includes a cabinet, cabinet doors, and an alarm. The cabinet doors are respectively located on the left and right sides of the front of the cabinet and are hinged to the cabinet. The alarm is located inside the cabinet door and is connected to the cabinet door by bolts. The live-line induction sensor is located inside the cabinet door and is connected to the cabinet door by bolts. A connecting wire is located between the alarm and the live-line induction sensor and is electrically connected to both the alarm and the live-line induction sensor. An amplifier is located in the middle of the connecting wire and is electrically connected to the connecting wire.

[0004] In the aforementioned application, the cooperation between the cabinet and the cabinet door components makes it difficult to lock the cabinet and the cabinet door when the converter is used in the cabinet during daily use. This can lead to accidents due to misoperation by non-staff members. Therefore, we propose a live induction warning device for wind turbine generator converters. Utility Model Content

[0005] The purpose of this utility model is to provide a live induction warning device for wind turbine generator converters. Through the cooperation of components such as locking rods, pull rods, and locking plates, after the operator completes routine maintenance of the converter, the operator closes the gate and pulls the pull rod through the moving slot, causing the pull rod to be pulled out of the moving slot. At this time, the force rod is not under force, and through the torsion spring shaft, the locking plate enters the locking slot to lock the gate and the housing, thus protecting the converter. This design achieves the effect of protecting the converter inside the housing, preventing accidents caused by unauthorized operation of the converter, and solving existing problems.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a live induction warning device for a wind turbine generator converter, including a housing, a door rotatably connected to the side of the housing, and a locking mechanism provided inside the housing;

[0008] The locking mechanism includes a fixing block, the side of which is fixedly connected to the side of the door. A locking rod is threaded inside the fixing block. A moving groove is opened inside the locking rod. A pull rod is slidably connected inside the moving groove. A support shaft is rotatably connected to the side of the pull rod. A pressing rod is fixedly connected to the circumferential surface of the support shaft.

[0009] Furthermore, the side of the gate is provided with an inlay groove, and a torsion spring shaft is rotatably connected inside the inlay groove. A force-bearing rod is fixedly connected to the circumferential surface of the torsion spring shaft. The purpose is to ensure that the force-bearing rod rotates through the torsion spring shaft under the force.

[0010] Furthermore, a locking plate is fixedly connected to the circumferential surface of the torsion spring shaft, and a locking groove is provided on the inner wall of the housing, the purpose of which is to ensure that the door can be locked stably.

[0011] Furthermore, the side of the force-bearing rod is located on the displacement trajectory of the extrusion rod, the purpose of which is to ensure that the movement of the extrusion rod can push the force-bearing rod.

[0012] Furthermore, the housing is equipped with an anti-theft mechanism, which includes a trigger rod. One end of the trigger rod is fixedly connected to one end of the lock rod. The housing is also equipped with a circuit breaker, and a switch is provided on the side of the circuit breaker. The purpose of the circuit breaker is to prevent thieves from stealing the converter and to warn thieves of danger.

[0013] Furthermore, an insulated handle is fixedly connected to the other end of the locking rod to prevent electric shock from workers during operation.

[0014] Furthermore, the side of the switch is located on the displacement trajectory of the trigger rod, ensuring that the movement of the trigger rod can compress the switch, thereby activating the circuit breaker.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model utilizes the cooperation between components such as locking rod, pull rod, and locking plate. After the operator completes routine maintenance of the converter, they close the gate and pull the pull rod through the moving slot, causing the pull rod to be pulled out of the moving slot. At this time, the force rod is not under force, and through the torsion spring shaft, the locking plate enters the locking slot to lock the gate and the housing, thus protecting the converter. This design achieves the effect of protecting the converter inside the housing and preventing accidents caused by unauthorized operation of the converter.

[0017] 2. This utility model utilizes the interplay between components such as the trigger rod, circuit breaker, and insulated handle. Simultaneously, the operator rotates the locking rod via the insulated handle, causing the trigger rod to move and press against the circuit breaker's switch, thus activating the circuit breaker. This energizes the housing and the stop gate. If a thief attempts to steal the converter and damages the locking plate, the circuit breaker's activation serves as a warning to the thief and simultaneously triggers an alarm to alert the operator. This design effectively prevents theft of the converter, thus avoiding the malfunction of the wind turbine generator.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] Please see Figure 1-5 This utility model is a live induction warning device for a wind turbine generator converter, including a housing 1, a door 2 rotatably connected to the side of the housing 1, and a locking mechanism 3 provided inside the housing 1.

[0029] The locking mechanism 3 includes a fixing block 31, the side of which is fixedly connected to the side of the gate 2. The fixing block 31 is threadedly connected to a locking rod 32. The locking rod 32 has a moving groove 33 inside. A pull rod 34 is slidably connected inside the moving groove 33. A support shaft 35 is rotatably connected to the side of the pull rod 34. A pressing rod 36 is fixedly connected to the circumferential surface of the support shaft 35.

[0030] The side of the gate 2 is provided with an inlay groove 37. A torsion spring shaft 38 is rotatably connected inside the inlay groove 37. A force-bearing rod 39 is fixedly connected to the circumferential surface of the torsion spring shaft 38. The purpose is to ensure that the force-bearing rod 39 rotates through the torsion spring shaft 38 under the force.

[0031] A locking plate 310 is fixedly connected to the circumferential surface of the torsion spring shaft 38, and a locking groove 311 is provided on the inner wall of the housing 1. The purpose is to ensure that the door 2 can be locked stably.

[0032] The side of the force-bearing rod 39 is located on the displacement trajectory of the extrusion rod 36, the purpose of which is to ensure that the movement of the extrusion rod 36 can push the force-bearing rod 39.

[0033] The housing 1 is equipped with an anti-theft mechanism, which includes a trigger rod 312. One end of the trigger rod 312 is fixedly connected to one end of the locking rod 32. The housing 1 is equipped with a circuit breaker 313. A switch 314 is provided on the side of the circuit breaker 313. Its purpose is to prevent thieves from stealing the converter and to warn thieves of danger.

[0034] An insulated handle 315 is fixedly connected to the other end of the locking rod 32 to prevent electric shock to workers during operation.

[0035] The side of switch 314 is located on the displacement trajectory of trigger rod 312, ensuring that the movement of trigger rod 312 can press switch 314, thereby activating circuit breaker 313.

[0036] A specific application of this embodiment is as follows: After the operator completes the routine maintenance of the converter, the operator closes the damper 2 and pulls the lever 34 through the moving groove 33, causing the lever 34 to move inside the moving groove 33. The lever 34 is under tension, which drives the pressing rod 36 to rotate through the support shaft 35. The pressing rod 36 moves, causing the lever 34 to be pulled out of the moving groove 33. At this time, the force rod 39 is not under thrust and is reset and rotated through the torsion spring shaft 38, causing the locking plate 310 to enter the locking groove 311 to lock the damper 2 and the housing 1, thus locking the converter. The converter is protected, and the staff rotates the locking rod 32 through the insulated handle 315, so that the locking rod 32 rotates and moves through the internal thread of the fixing block 31. The movement of the locking rod 32 drives the trigger rod 312 to move. During the movement of the trigger rod 312, it squeezes the switch 314 of the circuit breaker 313, causing the circuit breaker 313 to start. The housing 1 and the stop door 2 are energized. When a thief steals the converter and pries open the locking plate 310, the opening of the circuit breaker 313 serves as a danger warning to the thief and at the same time, an alarm is triggered to remind the staff.
