A 10kV generator car quick access cabinet

Abstract

This invention relates to the field of power distribution technology and discloses a 10kV generator vehicle quick-connect cabinet, including a cabinet body. The cabinet body has an equipment compartment and a cable compartment, with the cable compartment located below the equipment compartment. Equipment components are installed inside the equipment compartment. The cabinet features a double-fastening mechanism: by rotating the handle, the lead screw rotates synchronously under the meshing of the transmission gear and transmission ring gear. This causes the movable seat to move along the outside of the lead screw. Under the cross-movement of the first and second connecting rods, the extension plate can contract and extend, thereby driving the crimping member to contact and clamp the access cable. Simultaneously, a second spring pushes the connecting plate, causing the swing plate to swing, ensuring that the arc-shaped abutment remains in contact with the access cable. Under external force, the arc-shaped abutment ensures stability, thus achieving double fastening of the access cable, greatly improving the fastening effect and effectively preventing the access cable from loosening.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0030] Example 1, by Figures 1-9 The present invention includes a cabinet 1, and the cabinet 1 has an equipment room 2 and a cable room 3 respectively. The cable room 3 is located below the equipment room 2. The equipment room 2 is equipped with an equipment component 4. The upper part of the cable room 3 is equipped with a cable connector 5 connected to the equipment component 4. The cable connector 5 is provided with a fastening mechanism 6 for fastening the cable to prevent it from loosening. The front end of the cabinet 1 is rotatably connected to a front door 7. The left and right sides of the cabinet 1 are respectively rotatably connected to a left door 8 and a right door 9.

[0031] Fastening mechanism 6 includes a cylinder 601, with a first baffle 602 and a second baffle 603 connected to both ends of the cylinder 601. Three lead screws 604 are evenly distributed around the first baffle 602 and the second baffle 603. The two ends of the lead screws 604 are rotatably connected to the first baffle 602 and the second baffle 603, respectively. A fixed seat 605 is movably sleeved on the outer end of each of the three lead screws 604. The fixed seat 605 is connected to the side wall of the first baffle 602. A movable seat 606 is threaded onto the outside of each of the three lead screws 604. A sliding rod 625 is passed through the interior of both sides of the movable seat 606. The two ends of the sliding rod 625 are respectively connected to the first baffle 602 and the second baffle 603. The plate 602 is connected to the second baffle 603. The upper end of the movable seat 606 is rotatably connected to the first connecting rod 607. The upper part of the first connecting rod 607 is rotatably connected to the extension plate 608. The lower end of the extension plate 608 has connecting frames 609 distributed at equal angles around its circumference. The first connecting rod 607 is rotatably connected to the connecting frame 609. A long groove 610 is opened on one side wall of the connecting frame 609. The upper end of the fixed seat 605 is rotatably connected to the second connecting rod 611. The second connecting rod 611 is rotatably connected to the middle intersection point of the first connecting rod 607. A sliding pin 612 is connected to the upper part of the second connecting rod 611. The sliding pin 612 is slidably connected to the long groove 610.

[0032] Each of the three extension plates 608 has a pressing member 613 connected to one side. The pressing member 613 includes two fixing plates 6131 connected to the side end of the extension plate 608. Each of the two fixing plates 6131 has a T-shaped rod 6132 connected to its lower end. An installation plate 6133 is movably sleeved on the outside of the T-shaped rod 6132. A U-shaped frame 6134 is connected to the lower end of the installation plate 6133. The U-shaped frame 6134 is movably sleeved on the outside of the T-shaped rod 6132. A clamping block 6135 is connected to the middle of the lower end of the U-shaped frame 6134.

[0033] A threaded rod 6136 is connected to the middle of the upper end of the mounting plate 6133. An adjusting plate 6137 is movably sleeved on the outside of the threaded rod 6136. The adjusting plate 6137 is movably sleeved on the outside of the T-shaped rod 6132. A wing nut 6138 is threaded onto the upper part of the threaded rod 6136. The wing nut 6138 is located at the upper end of the adjusting plate 6137. A first spring 6139 is provided between the adjusting plate 6137 and the mounting plate 6133. The first spring 6139 is sleeved on the outside of the T-shaped rod 6132.

[0034] By tightening and loosening the wing nut 6138, the adjusting plate 6137 can slide along the outside of the T-shaped rod 6132, so that the distance between the adjusting plate 6137 and the mounting plate 6133 can be adjusted.

[0035] When the distance between the adjusting plate 6137 and the mounting plate 6133 decreases, the elastic force of the first spring 6139 increases; conversely, when the distance between them increases, the elastic force of the first spring 6139 decreases; thus, the force during elastic clamping can be controlled.

[0036] A lug seat 61310 is connected to one side of the U-shaped frame 6134. A swing plate 61311 is rotatably connected inside the lug seat 61310. An arc-shaped abutment 61312 is provided at the lower end of the swing plate 61311. A connecting plate 61313 is connected to the upper end of the swing plate 61311. A second spring 61314 is connected between the connecting plate 61313 and the U-shaped frame 6134.

[0037] One end of each of the three lead screws 604 extends to one side of the second baffle 603 and is connected to a transmission gear 614. One of the extended sections of the lead screw 604 is connected to a handle 615. The inner side of the three transmission gears 614 is provided with a transmission gear ring 616. The transmission gear ring 616 is rotatably connected to the cylinder 601 through a bearing. The transmission gear ring 616 is meshed with the three transmission gears 614.

[0038] The first baffle 602 has mounting screws 617 distributed at equal angles around its circumference. The mounting screws 617 pass through the first baffle 602 and are threadedly connected to the top wall of the cable chamber 3. One end of the mounting screw 617 is connected to a rotating block 618. The two mounting screws 617 are threadedly fitted with first locking nuts 619 on both sides of the first baffle 602. The two first locking nuts 619 contact the two side walls of the first baffle 602 respectively. The mounting screw 617 is threadedly fitted with a second locking nut 620 on the side near its end. The second locking nut 620 contacts the top wall of the cable chamber 3.

[0039] A positioning block 621 is fixedly connected to one side of the second baffle 603. A pull rod 622 is movably passed through the positioning block 621. One end of the pull rod 622 is connected to an arc-shaped toothed plate 623. The arc-shaped toothed plate 623 meshes with the transmission gear ring 616. A third spring 624 is sleeved on the outside of the pull rod 622. One end of the third spring 624 is connected to the positioning block 621, and the other end of the third spring 624 is connected to the arc-shaped toothed plate 623.

[0040] Working principle: When in use, the access cable passes through the inside of the cylinder 601 in the fastening mechanism 6 and comes out from the other end, so that the access cable is plugged into the cable connector 5;

[0041] Rotating the handle 615 drives the lead screw 604 connected to it to rotate. The lead screw 604 drives the other two lead screws 604 to rotate synchronously through the meshing of the transmission gear 614 and the transmission gear ring 616. As the lead screw 604 rotates, the movable seat 606 moves along the thread direction on the lead screw 604.

[0042] The movement of the movable seat 606 drives the extension plate 608 to move through the first connecting rod 607. At the same time, the sliding pin 612 on the second connecting rod 611 slides in the long groove 610 of the connecting frame 609. The first connecting rod 607 and the second connecting rod 611 move in a cross motion around their connection intersection to ensure the smooth movement of the extension plate 608. At this time, the three extension plates 608 gradually retract towards the cylinder 601.

[0043] The movement of the three extension plates 608 causes the three crimping members 613 to gradually move closer to the center until the clamping block 6135 contacts the outside of the access cable. Then, the three crimping members 613 continue to move closer and retract. This causes the clamping block 6135 to drive the U-shaped frame 6134 to abut against the mounting plate 6133 outward, thereby generating a holding force on the first spring 6139. Under the action of the spring force of the first spring 6139, the clamping block 6135 has a holding force on the side of the access cable, which can clamp the access cable.

[0044] On the other hand, while clamping the access cable, the clamping block 6135, under the action of the second spring 61314, pushes the connecting plate 61313 to drive the swing plate 61311 to rotate around the ear plate seat 61310, so that the arc-shaped abutment 61312 remains in contact with the access cable. Since the arc-shaped abutment 61312 is always in contact with the access cable and its contact surface is arc-shaped, even if the access cable is subjected to external force, when the access cable moves outward, it generates a mutual squeezing force with the arc-shaped abutment 61312. The arc-shaped abutment 61312 can effectively prevent the access cable from loosening and detaching.

[0045] When the predetermined fastening position is reached, the handle 615 stops turning, all lead screws 604 stop rotating, the movable seat 606 and the extension plate 608 remain in the current position, and the crimping member 613 stably clamps the access cable. At this time, the arc-shaped toothed plate 623 can engage with the transmission toothed ring 616, and the third spring 624 provides a holding force to maintain the stability of the mechanism.

[0046] When unlocking is required, pull the lever 622 to separate the arc-shaped toothed plate 623 from the transmission toothed ring 616, thereby restoring the normal rotation function of the lead screw 604. By rotating the handle 615, the three extension plates 608 are driven to gradually extend, thereby causing the three crimping parts 613 to separate from the access cable. After that, the access cable can be removed by unplugging the connection between the access cable and the cable connector 5.
