DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figures 1-4 The utility model discloses a wind power maintenance and repair device, comprising an electric power repair instrument 1 installed in a box body 2. The electric power repair instrument 1 may be a power quality analyzer. The electric power repair instrument 1 is fixedly installed in the box body 2 by bolts. A box cover 3 is hinged on the box body 2. A handle 4 is also installed in the middle of the front end of the box body 2 for lifting the device.

[0025] The device also includes a buckle 6 for snapping the box body 2 and the box cover 3, the buckle 6 includes a snap-in groove 601 which is opened in the power maintenance instrument 1 and has an opening on the top, a snap-in block 613 which corresponds to the snap-in groove 601 and is fixed on the box cover 3, a snap-in pin 607 which has a retractable side of the snap-in groove 601 and is snap-in engaged with the snap-in block 613, and a shifting block 603 for shifting the snap-in pin 607 is installed on the front end surface of the box body 2.

[0026] The buckle 6 is located on the left and right sides of the inner side of the power maintenance instrument 1 near the front end surface. When in use, the shift block 603 is pushed to drive the card pin 607 to separate from the card plug block 613, thereby opening the box cover 3.

[0027] The buckle 6 includes a clamping seat 606 which is fixedly installed inside the power maintenance instrument 1. A clamping groove 601, a lever groove 605, and a pin slot 609 are formed inside the clamping seat 606. The clamping pin 607 is slidably installed along the axial direction in the pin slot 609. A lever 604 is slidably installed in the lever groove 605 along the sliding direction of the clamping pin 607. Both ends of the lever 604 are respectively connected to the clamping pin 607 and the lever block 603. The lever groove 605 penetrates through the side walls of the clamping seat 606 and the box body 2 along the lever 604. When the lever block 603 is toggled, the lever block 603 drives the clamping pin 607 to slide in the pin slot 609 through the lever 604, so that the clamping pin 607 is separated from the clamping plug 613.

[0028] A first spring 610 is installed inside the pin slot 609. Both ends of the first spring 610 are respectively connected to the clamping pin 607 and the pin slot 609. The initial state of the first spring 610 is to push the clamping pin 607 into the clamping groove 601.

[0029] A lever block groove 602 is machined on the front surface of the box body 2. The lever block 603 is slidably installed in the lever block groove 602, which reduces the exposure of the lever block 603, reduces the bumping of the lever block 603, and reduces misoperation.

[0030] A second spring 611 is installed at the bottom of the clamping groove 601. A dust-proof block 612 is arranged at the top of the second spring 611. The side wall of the dust-proof block 612 is attached to the inner wall of the clamping groove 601. The dust-proof block 612 is slidably installed vertically in the clamping groove 601. When the clamping pin 607 is toggled to be separated from the clamping plug 613, the clamping plug 613 is driven by the dust-proof block 612 to automatically open the box cover 3 upward, making it more convenient to open the box cover 3.

[0031] The initial state of the second spring 611 is to push the dust-proof block 612 upward to a position flush with the top end of the clamping groove 601. After the box cover 3 is opened, the dust-proof block 612 automatically aligns with the top opening of the clamping groove 601 under the elastic action of the second spring 611, thereby preventing sundries from entering the clamping groove 601 and causing blockage.

[0032] At the same time, every time the dust-proof block 612 aligns with the opening of the clamping groove 601, it can also block the clamping pin 607, preventing the end of the clamping pin 607 from extending into the clamping groove 601. Thus, when the clamping plug 613 is inserted into the clamping groove 601, the clamping plug 613 can be automatically clamped with the clamping pin 607 without manually toggling the lever block 603.

[0033] A clamping hole 608 corresponding to the clamping pin 607 is formed on the clamping plug 613, specifically as Figure 4When the card pin 607 is aligned with the card hole 608, the end of the card pin 607 is inserted into the card hole 608, thereby being engaged with the card block 613 to clamp the box cover 3.

[0034] The device also includes a lock buckle 5, which includes a lock body 501 installed in front of the box body 2 and a lock tongue 502 installed in front of the box cover 3. After the box cover 3 is closed, the lock tongue 502 is inserted into the lock body 501 to lock the box cover 3 to prevent non-staff from opening the box cover 3.

[0035] Working principle: when in use, first open the lock buckle 5, then move the shift block 603, the shift block 603 drives the card pin 607 to disengage from the card hole 608, the card pin 607 is separated from the card plug block 613, and the card plug block 613 drives the box cover 3 to automatically open one end distance upward under the push of the dust block 612. At the same time, the dust block 612 blocks the card pin 607 during the rising process. When the dust block 612 rises to the top, it is aligned with the opening of the card slot 601, and then the staff can open the box cover 3 normally and use the power maintenance instrument 1;

[0036] When closing the box cover 3, the box cover 3 drives the card plug block 613 to be inserted into the card slot 601. When the card plug block 613 is inserted into the card slot 601, the dust block 612 is pushed downward. When the card hole 608 is aligned with the card pin 607, the card pin 607 is automatically inserted into the card hole 608 under the elastic action of the first spring 610, the box cover 3 is clamped, and finally the lock buckle 5 is locked.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
