[0025] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0026] Example 1 Reference Figure 1 - Figure 10 This is the first embodiment of the present invention. This embodiment provides an intelligent monitoring and control device for power distribution networks, which includes a monitoring and control mechanism, an auxiliary mechanism and a buffer mechanism. It can prevent the protective door 11 from being damaged when the staff closes it forcefully, and at the same time, it can prevent the vibration of the protective door 11 from affecting the monitoring and control equipment inside the cabinet 10. The internal slide rail 173 of the cabinet 10 can be locked and unlocked according to the opening and closing angle of the protective door 11, which facilitates the staff to adjust and maintain the monitoring and control equipment on the support frame 15.
[0027] Furthermore, the measurement and control mechanism facilitates the installation of the measurement and control equipment inside the cabinet 10 by staff, while also facilitating subsequent maintenance of the equipment. This includes the cabinet 10 and the protective door 11. A flip-up part 12 is provided between the cabinet 10 and the protective door 11. Two U-shaped rods 13 are installed on the inner wall of the cabinet 10, evenly distributed on the inner wall of the cabinet 10. A support plate 14 is provided on the U-shaped rod 13. A support frame 15 for placing the measurement and control equipment is provided on the top of the support plate 14. A sliding groove 16 is provided on the support plate 14, and the U-shaped rod 13 is located inside the sliding groove 16. A movable part 17 is provided at the bottom of the support plate 14. A locking part 18 for limiting the position of the support plate 14 is provided on the bottom surface inside the cabinet 10.
[0028] It should be noted that the U-shaped rod 13 and the slide 16 can restrict the support plate 14, so that the support plate 14 can only move in one direction inside the cabinet 10.
[0029] Furthermore, the flipping part 12 includes a fixing seat 121 disposed on the cabinet 10. There are three fixing seats 121, which are evenly distributed on the cabinet 10 from top to bottom. A long rod 122 is disposed on the fixing seat 121. All three fixing seats 121 are disposed on the side wall of the long rod 122. A flipping plate 123 is disposed on the long rod 122, and the flipping plate 123 is connected to the protective door 11.
[0030] When in use, when the staff pulls the protective door 11, the protective door 11 can drive the flip plate 123 to rotate. The flip plate 123 drives the long rod 122 to rotate on the fixed seat 121, and the protective door 11 provides a simple seal for the cabinet 10.
[0031] Furthermore, the movable part 17 includes a base 171 disposed at the bottom of the support plate 14. There are two bases 171, which are evenly distributed at the bottom of the support plate 14. Rollers 172 are disposed on the bases 171. There are multiple rollers 172, which are evenly distributed on the bases 171. A slide rail 173 is disposed on the bottom surface inside the cabinet 10, and the rollers 172 are located inside the slide rail 173.
[0032] It should be noted that the U-shaped rod 13 and the slide groove 16 are designed to ensure that the support plate 14 can move smoothly and to prevent the support plate 14 from tilting when some of the rollers 172 are disengaged from the slide rail 173.
[0033] When in use, when the staff pulls the support frame 15, the support frame 15 can drive the support plate 14 to move, and the support plate 14 can drive the roller 172 to move on the slide rail 173, so that the support plate 14 drives the measurement and control equipment to gradually extend out of the cabinet 10, making it convenient for the staff to adjust and maintain the measurement and control equipment on the support frame 15.
[0034] Furthermore, the locking part 18 includes a U-shaped block 181 disposed on the bottom surface inside the cabinet 10. The U-shaped block 181 is located in the middle of the side wall of the support plate 14. A stop block 182 is disposed inside the U-shaped block 181. The stop block 182 is slidably connected to the U-shaped block 181. A first spring 183 is disposed on the stop block 182. The end of the first spring 183 away from the stop block 182 is connected to the bottom surface inside the U-shaped block 181. There are multiple first springs 183, which are evenly distributed at the bottom of the stop block 182.
[0035] It should be noted that, in the initial state, with the setting of the first spring 183 and the stop 182, when the support plate 14 is located inside the cabinet 10, one side of the stop 182 contacts the side wall of the support plate 14. The stop 182 can prevent the support plate 14 from detaching from the inside of the cabinet 10 under the action of the roller 172.
[0036] When the measuring and control equipment needs to be installed inside the cabinet 10, the operator first presses the stop block 182. The stop block 182 causes the first spring 183 to contract, so that the top of the stop block 182 is lower than the bottom of the support plate 14. At this time, the operator pulls the support frame 15, which drives the support plate 14. The support plate 14 causes the roller 172 on the base 171 to disengage from the slide rail 173, finally moving the support frame 15 to the outside of the cabinet 10. This makes it convenient for the operator to install the measuring and control equipment on the support frame 15. After the measuring and control equipment is installed, the operator pushes the support frame 15 back into the cabinet 10.
[0037] Furthermore, the auxiliary mechanism controls the lifting and lowering of the stop block 182 according to the opening and closing angle of the protective door 11, further improving the work efficiency of the staff. This includes a fixing block 20 on the cabinet 10, a crossbar 21 on the fixing block 20, and a pressing part 22 and a reset part 23 on the side wall of the crossbar 21.
[0038] It should be noted that by setting the fixing block 20, the position of the crossbar 21 is determined, while ensuring that the crossbar 21 can only move laterally.
[0039] Furthermore, the extrusion section 22 includes two limiting rings 221 disposed on the side wall of the crossbar 21. The two limiting rings 221 are respectively located on both sides of the stop block 182. The limiting rings 221 are installed on the side wall of the U-shaped block 181. The stop block 182 is provided with a first inclined groove 222 and a transverse groove 223. A fixing sleeve 224 is disposed on the side wall of the crossbar 21. The side wall of the fixing sleeve 224 contacts the side wall of the stop block 182. A first extrusion rod 225 is installed on the fixing sleeve 224. The first extrusion rod 225 is located inside the first inclined groove 222.
[0040] It should be noted that by setting the fixing sleeve 224, the rotation of the crossbar 21 can be prevented.
[0041] When in use, when the crossbar 21 is squeezed from left to right, the crossbar 21 drives the fixed sleeve 224 to move. The fixed sleeve 224 drives the first pressing rod 225 to squeeze the first inclined groove 222, causing the stop block 182 to descend and drive the first spring 183 to contract. When the first pressing rod 225 is inside the cross groove 223, the top of the stop block 182 is located below the bottom of the support plate 14, so that the support plate 14 does not contact the stop block 182 during the movement, thus avoiding the stop block 182 from giving the bottom of the support plate 14 friction when the support plate 14 is pulled.
[0042] Furthermore, the reset part 23 includes a second spring 231 disposed on the fixing block 20. The end of the second spring 231 away from the fixing block 20 is connected to a fixing ring 232, which is sleeved on the side wall of the crossbar 21.
[0043] It should be noted that when the crossbar 21 is compressed, the crossbar 21 drives the fixed ring 232 to move. When the fixed ring 232 moves, it compresses the second spring 231. When the compression on the crossbar 21 is removed, the second spring 231 is used to drive the crossbar 21 back to its initial position.
[0044] Furthermore, the buffer mechanism protects the protective door 11 while preventing it from impacting the cabinet 10, thus preventing the vibration from the impact from affecting the monitoring and control equipment inside the cabinet 10. It locks the stop block 182 simultaneously with the opening and closing of the protective door 11. It also restricts the position of the protective door 11 at different angles, preventing it from freely flipping. This includes an arc-shaped tube 30 on the cabinet 10, with a first through-hole 31 at one end and multiple air holes 32 on its sidewall. A buffer section 33 is located inside the arc-shaped tube 30, and a pneumatic section 34 is installed on the buffer section 33. A fixing plate 35 is installed on the sidewall of the protective door 11, with the end of the fixing plate 35 away from the protective door 11 connected to a long rod 122. The fixing plate 35 has a follower section 36 and a pusher section 37. An unlocking section 38 is located at the bottom of the support plate 14, and an ejector section 39 is installed on the cabinet 10.
[0045] Furthermore, the buffer part 33 includes a first ring 331 disposed inside the arc-shaped tube 30, a third spring 332 disposed on the first ring 331, a sealing block 333 connected to the end of the third spring 332 away from the first ring 331, and the end of the sealing block 333 away from the third spring 332 in contact with the second fixing ring 232.
[0046] When in use, when the sealing block 333 is squeezed, the sealing block 333 drives the third spring 332 to contract, and at the same time, the gas inside the arc tube 30 is discharged through the air hole 32.
[0047] It should be noted that the diameter of the air hole 32 is 2mm. Due to the small diameter of the air hole 32, the movement speed of the sealing block 333 inside the arc tube 30 can be further limited by the cooperation of the air hole 32 and the third spring 332.
[0048] Furthermore, the pneumatic part 34 includes a groove 341 and a second through-hole 342 disposed on the sealing block 333, the groove 341 and the second through-hole 342 communicating with each other.
[0049] It should be noted that when the second through-hole 342 is sealed, the gas inside the arc-shaped tube 30 can only be discharged through the vent 32. When the second through-hole 342 is not sealed, it is convenient for external gas to quickly enter the interior of the arc-shaped tube 30.
[0050] Furthermore, the follower part 36 includes an arc-shaped rod 361 disposed on the fixed plate 35, and a rubber ring 362 is provided on the side wall of the arc-shaped rod 361.
[0051] It should be noted that when the protective door 11 flips, it causes the fixing plate 35 to flip, the fixing plate 35 causes the arc rod 361 to move, and the arc rod 361 causes the rubber ring 362 to move. When the protective door 11 seals the cabinet 10, one end of the sealing block 333 contacts the first ring 331. When the angle between the protective door 11 and the cabinet 10 is 70°-90°, the position of the arc rod 361 can be simply restricted by the setting of the third spring 332, the sealing block 333, the first through hole 31 and the rubber ring 362, so as to prevent the protective door 11 from flipping freely.
[0052] Furthermore, the pushing part 37 includes a push block 371 disposed on the fixing plate 35. The push block 371 is located on the side away from the arc-shaped rod 361. The push block 371 is mounted on the side wall of the long rod 122. A slot 372 is provided on the side wall of the push block 371. The cross-sectional dimensions of the end of the slot 372 are adapted to the cross-sectional dimensions of one end of the cross rod 21, and the cross rod 21 and the slot 372 are located on the same horizontal line.
[0053] In use, when the protective door 11 rotates together with the fixing plate 35 and the long rod 122, the fixing plate 35 drives the push block 371 to move. As the protective door 11 gradually flips and becomes parallel to the crossbar 21, the push block 371 can push the crossbar 21 to move laterally. When the protective door 11 is parallel to the crossbar 21, the fixing ring 232 can be moved under the action of the second spring 231. The fixing ring 232 drives the crossbar 21 to insert into the slot 372. At this time, the first pressing rod 225 is still located inside the horizontal groove 223, which completes the locking of the position of the push block 371 and prevents the protective door 11 from flipping on its own.
[0054] Furthermore, the unlocking part 38 includes a storage groove 381 located at the bottom of the support plate 14. The interior of the storage groove 381 is connected to a second pressing rod 382 via a pivot. The top of the stop block 182 is provided with a through groove 383. The second pressing rod 382 is located directly above the through groove 383. The top of the fixing sleeve 224 is provided with a second inclined groove 384.
[0055] It should be noted that, through the arrangement of the storage slot 381 and the second pressing rod 382, the second pressing rod 382 can only be rotated in one direction inside the storage slot 381. When the crossbar 21 is located inside the slot 372, the inclined slot and the through slot 383 are interconnected, and the through slot 383 and the inclined slot are located on the same horizontal plane.
[0056] In use, when the stop block 182 is below the support plate 14, and the support plate 14 is pulled out from the inside of the cabinet 10, the support plate 14 drives the second pressing rod 382 to contact the second inclined groove 384 through the through groove 383. The second inclined groove 384 will drive the second pressing rod 382 to flip, so that the second pressing rod 382 enters the inside of the storage groove 381. When the second pressing rod 382 has completely passed through the fixing sleeve 224, under the action of gravity, the second pressing rod 382 flips back and becomes perpendicular to the ground. When the support plate 14 re-enters and is pushed into the inside of the cabinet 10, the support plate 14 drives the second pressing rod 382 to move. The second pressing rod 382 presses the second inclined groove 384, so that the fixing sleeve 224 moves to the right. The fixing sleeve 224 drives the crossbar 21 to move, so that the crossbar 21 disengages from the inside of the slot 372, releasing the restriction on the push block 371.
[0057] Furthermore, the ejector part 39 includes an ejector block 391 disposed on the cabinet 10, an extension tube 392 disposed on the ejector block 391, and a fourth spring 393 disposed inside the extension tube 392.
[0058] During use, the push block 371 flips and squeezes the telescopic tube 392, which in turn causes the fourth spring 393 to retract. When the crossbar 21 is disengaged from the inside of the slot 372, the fourth spring 393 returns to its original position and can cause the telescopic tube 392 to squeeze the push block 371. The push block 371 then drives the fixing plate 35, which in turn causes the protective door 11 to flip slightly, preventing the crossbar 21 from being reinserted into the slot 372.
[0059] Working principle: When staff need to debug the monitoring and control equipment inside cabinet 10, they pull the handle on protective door 11 to open it. During the opening process, the flip plate 123 and the fixing plate 35 flip together. The flip plate 123 drives the long rod 122 to rotate, and the fixing plate 35 drives the arc rod 361 to extend out from the inside of the arc tube 30. At the same time, the third spring 332 returns to its initial state, causing the sealing block 333 to move. When the third spring 332 returns to its initial state, the arc rod 361 separates from the sealing block 333 as the arc rod 361 moves. When the rubber ring 362 on the arc rod 361 contacts the inner wall of the arc tube 30, the protective door 11 opens 90°. The rubber ring 362 prevents the protective door 11 from continuing to flip outward. At this time, staff can debug the monitoring and control equipment inside cabinet 10.
[0060] When inspecting the control equipment inside the cabinet 10, to facilitate operation, the control equipment on the support plate 14 needs to be removed from the inside of the cabinet 10. At this time, with the protective door 11 open to 90°, the operator continues to push the protective door 11 outward to rotate it, causing the arc rod 361 to drive the rubber ring 362 to detach from the inside of the arc tube 30 through the first through-hole 31. At the same time, the fixing plate 35 drives the push block 371 to rotate around the long rod 122. When the push block 371 contacts the telescopic rod and the crossbar 21, the push block 371 can push the crossbar 21. When the pusher 371 moves, it can cause the telescopic tube 392 to retract, causing the fourth spring 393 to retract. When the crossbar 21 moves, it causes the fixing ring 232 and the fixing sleeve 224 to move together, causing the fixing ring 232 to compress the second spring 231, causing the second spring 231 to retract. The fixing sleeve 224 causes the first pressing rod 225 and the second inclined groove 384 to move together. The first pressing rod 225 compresses the inner wall of the first inclined groove 222, causing the stop block 182 to descend inside the U-shaped block 181. The descent of the stop block 182 causes the first spring 183 to retract. When the protective door 11... When rotated 180°, the first pressing rod 225 moves into the interior of the transverse groove 223 under the action of the crossbar 21. At the same time, the crossbar 21 is inserted into the interior of the slot 372 under the restoration of the second spring 231, completing the locking of the protective door 11 and preventing the protective door 11 from rotating due to wind or touch, thus affecting the maintenance of the measurement and control equipment by the staff. At this time, the second inclined groove 384 and the through groove 383 are interconnected, and the stop block 182 is located directly below the support plate 14. At this time, the staff can pull the support frame 15, which can drive the support plate 14 towards the cabinet 1. When the support plate 14 moves to the outside of the cabinet 10, the roller 172 moves inside the slide rail 173. The support plate 14 moves together with the second pressing rod 382. When the second pressing rod 382 contacts the second inclined groove 384 through the through groove 383, the second inclined groove 384 can drive the second pressing rod 382 to flip into the inside of the storage groove 381. When the second pressing rod 382 passes through the fixing sleeve 224, it returns to its initial state. After the support plate 14 moves to the outside of the cabinet 10, the staff can inspect the measurement and control equipment on the support frame 15.
[0061] After the monitoring and control equipment is repaired, the staff pushes the support frame 15, which in turn moves the support plate 14 into the cabinet 10. When the support plate 14 moves the second extruder into the second inclined groove 384, it can compress the second inclined groove 384, thereby causing the fixing sleeve 224 to move to the right. The fixing sleeve 224 moves the crossbar 21, and the crossbar 21 causes the second spring 231 to further contract, causing the crossbar 21 to disengage from the slot 372, thus unlocking the protective door 11. At the same time, the fourth spring 393 recovers, causing the telescopic tube 392 to extend and compress the push block 371. The push block 371 moves the fixing plate 35, and the fixing plate 35 causes the protective door 11 to tilt slightly. The rotation causes one end of the crossbar 21 to be misaligned with the slot 372. At this time, when the second pressing rod 382 enters the interior of the through slot 383, the compression on the second inclined slot 384 is released. The second spring 231 resumes driving the fixed ring 232 to move. The fixed ring 232 drives the crossbar 21 to press the push block 371. The push block 371 drives the fixed piece 35 to flip. The fixed piece 35 drives the protective door 11 to flip. When the push block 371 is completely separated from the crossbar 21, under the action of the first spring 183 and the second spring 231, the first pressing rod 225 re-enters the interior of the first inclined slot 222. The stop block 182 re-locks the support plate 14, preventing the support plate 14 from sliding out of the cabinet 10.
[0062] When the staff closes the protective door 11, to prevent damage to the protective door 11 due to wind or forceful closure, the protective door 11, along with the fixing plate 35 and the flip plate 123, flips together during the closing process. The fixing plate 35 drives the arc rod 361 to insert into the interior of the arc tube 30. When the arc rod 361 is inserted into the interior of the groove 341, it can seal the second through-hole 342, slowing down the air discharge speed inside the arc tube 30. The staff needs to continuously push the protective door 11 so that the arc rod 361 drives the sealing block 333 to move. The sealing block 333 drives the fourth spring 393 to contract while squeezing the gas inside the arc tube 30. The gas is discharged from the air hole 32 until the protective door 11 seals the cabinet 10, preventing the protective door 11 from colliding rapidly with the cabinet 10.
