Description

Technical Field

[0002] The distribution cabinet is divided into power distribution cabinet, lighting distribution cabinet and metering cabinet. It is the final equipment of the power distribution system. The distribution cabinet is a general term for the motor control center. The distribution cabinet is used in the occasions where the load is relatively dispersed and there are fewer circuits. The motor control center is used in the occasions where the load is concentrated and there are more circuits. They distribute the power of a circuit of the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load. The long-term use of the distribution cabinet is prone to line aging, which will cause faults such as poor contact of the internal lines of the distribution cabinet. A large number of wire harnesses in the distribution cabinet are stored in the wire trough. The staff needs to check the lines in the wire trough one by one;

However, the holes in the side walls of the cable trough are narrow, and there are many blind spots when the flashlight shines into the interior of the cable trough, which can easily cause omissions in the staff's observation. Secondly, the process of disassembling and installing the cable trough is very cumbersome. If it is disassembled for inspection, it will seriously affect the staff's maintenance efficiency.

[0031] See also Figure 1-Figure 4 The present invention provides a technical solution: a built-in fault inspection and maintenance auxiliary device for a power distribution cabinet, comprising a power distribution cabinet body 1, a cable trough 2, switch covers 3 are installed at the ends of the cable trough 2, and tracks 4 are fixedly installed on the inner walls of the top of the cable trough 2, a T-shaped block 5 is slidably connected to the inner side of the track 4, a mounting column 6 is fixedly installed at the bottom end of the T-shaped block 5, and a plurality of walking rods 7 are arranged on the outer side of the mounting column 6 through a driving mechanism, the driving mechanism is used to drive the walking rods 7 to pass through the holes of the side wall of the cable trough 2 one by one, and drive the T-shaped block 5 to slide in the track 4, a mounting plate 8 is arranged at the bottom end of the mounting plate 8 through a switching mechanism, a fill light 9 is installed at the bottom of the right end of the mounting plate 8, and the switching mechanism is used to drive the mounting plate 8 to rotate half a circle when the T-shaped block 5 moves to the end of the track 4;

[0032] The driving mechanism includes a mounting sleeve 10 rotatably connected to the outside of the mounting column 6, a first friction ring 11 is fixedly installed on the outside of the top of the mounting sleeve 10, a mounting frame 12 is fixedly installed on the right side of the top of the mounting column 6, a motor 13 is fixedly installed on the right end of the mounting frame 12, a first friction disk 14 is fixedly installed on the output end of the motor 13, a mounting rod 15 is slidably connected to the middle of the mounting frame 12, a friction cylinder 16 is rotatably connected to the outside of the mounting rod 15, the left side of the top of the friction cylinder 16 is transmission-connected to the first friction ring 11, and the right side of the bottom end of the friction cylinder 16 is transmission-connected to the first friction disk 14, a chuck 17 is fixedly installed on the top of the mounting rod 15, and the outer side of the bottom end of the mounting sleeve 10 is connected to a plurality of walking rods 7 through an adjusting mechanism, and the adjusting mechanism is used to adjust the distance between the walking rod 7 and the mounting sleeve 10;

[0033] During operation, when the staff needs to inspect the line in the line groove 2, they only need to open the switch cover 3 first, and then insert the T-shaped block 5 from the opening of the track 4. At this time, part of the walking rod 7 is inserted into the hole on one side of the line groove 2, and then the motor 13 is started. The motor 13 starts to drive the friction cylinder 16 to rotate through the first friction disk 14, and the rotation of the friction cylinder 16 drives the first friction ring 11 to rotate. The rotation of the first friction ring 11 drives the installation sleeve 10 to rotate. The rotation of the installation sleeve 10 drives a number of walking rods 7 to rotate around the installation column 6 as the axis through the adjustment mechanism. At this time, the ends of the walking rods 7 are inserted into the holes on one side of the line groove 2 in turn, and the inner wall of the hole is squeezed to push the installation column 6 and the T-shaped block 5 to move inside the line groove 2. When the installation column 6 moves, the fill light 9 continues to irradiate from one side of the line groove 2 to the other side inside it, thereby illuminating the line on one side inside the line groove 2. The staff can observe the line on one side inside the line groove 2 through the hole from the outside of the line groove 2, so as to find out the location where the fault occurs and the damage occurs.

[0034] When the T-block 5 moves to the other end of the track 4, the switching mechanism drives the mounting plate 8 to rotate 180° with the mounting column 6 as the axis. At this time, the fill light 9 flips to the other side of the device, and the motor 13 drives the first friction disk 14 to rotate in the opposite direction. The first friction disk 14 rotates in the opposite direction to make the T-block 5 and the mounting column 6 move to the initial position. At this time, the fill light 9 illuminates the line on the other side of the inner wall of the line groove 2. The staff only needs to move to the other side of the line groove 2 for observation, so that the staff can easily observe the lines in a group of line grooves 2 in a comprehensive manner, avoiding the situation that blind spots are easily generated when irradiating from the outside of the line groove 2 to the inside, thereby preventing Omissions occur when finding faults, which brings convenience to the staff's fault inspection and repair work; by setting the drive, the device can be moved inside the cable trough 2 while performing fill-in lighting, and the range of light irradiation is more comprehensive. The staff's line of sight moves with the position of the fill-in light 9, making the observation more detailed. Separate observation from both sides of the cable trough 2 avoids obstruction between the lines, making each line inside the cable trough 2 easier to observe, further reducing omissions during fault inspection and repair, and solving the problem that the built-in fault inspection and repair auxiliary device of the existing distribution cabinet cannot illuminate and assist in the inspection of the lines inside the cable trough 2.

[0035] See also Figure 4 , Figure 5 , Figure 6 , Fig.10As a further solution of the present invention, the adjustment mechanism includes a plurality of mounting frames 18 fixedly mounted on the outer side of the bottom end of the mounting sleeve 10 and corresponding to the walking rod 7 one by one, a slider 19 is fixedly mounted on the bottom of one end of the walking rod 7 close to the mounting sleeve 10, the slider 19 passes through the mounting frame 18 and is slidably connected thereto through a tension spring, a mounting ring 20 is rotatably connected to the outer side of the mounting sleeve 10, a plurality of extrusion blocks 21 corresponding to the walking rod 7 one by one are fixedly mounted on the outer side of the mounting ring 20, the extrusion blocks 21 are all fitted with adjacent walking rods 7, a transmission mechanism is arranged at the top of the mounting ring 20, the transmission mechanism is used for when the walking rod 7 is adjusted to be telescopic, the motor 13 is started to directly drive the mounting ring 20 to rotate, a synchronization mechanism is arranged at the bottom end of the first friction ring 11, the synchronization mechanism is used for when the walking rod 7 is not adjusted, the mounting sleeve 10 and the mounting ring 20 are rotated synchronously, and when the walking rod 7 is adjusted, the mounting ring 20 is unlocked;

[0036] During operation, when encountering different sizes of line grooves 2, the synchronization mechanism first unlocks the mounting sleeve 10 and the mounting ring 20, and then starts the motor 13. The motor 13 starts to drive the mounting ring 20 to rotate on the outside of the mounting sleeve 10 through the transmission mechanism. The rotation of the mounting ring 20 drives a number of extrusion blocks 21 to move synchronously. The extrusion blocks 21 move so that their side walls squeeze the walking rod 7. The walking rod 7 is squeezed and drives the slider 19 to slide in the installation frame 18. At this time, the installation frame 18 limits the movement of the slider 19, so that the walking rod 7 can only be telescopically moved along the top of the installation frame 18 until the walking rod 7 is moved to a suitable position at the top of the installation frame 18. At this time, when the T-shaped block 5 is inserted into the track 4, the end of part of the walking rod 7 can just be inserted into the hole on the side wall of the line groove 2, so that the device can be used in line grooves 2 of different sizes, which increases the applicability of the device.

[0037] See also Figure 4-Figure 6 As a further solution of the present invention, the transmission mechanism includes a connecting sleeve 22 fixedly installed at the top of the mounting ring 20, a second friction ring 23 is slidably connected to the outer side of the connecting sleeve 22, a plurality of lifting blocks 24 are fixedly installed on the inner wall of the second friction ring 23, a plurality of lifting grooves 25 corresponding to the lifting blocks 24 are opened on the outer side of the connecting sleeve 22, the lifting blocks 24 pass through the lifting grooves 25 and are slidably connected thereto, a second friction disc 26 is fixedly installed at the bottom end of the mounting rod 15, the second friction disc 26 is transmission-connected to the second friction ring 23, a push-pull mechanism is arranged at the bottom end of the second friction disc 26, and the push-pull mechanism is used to drive the second friction ring 23 to rise and fall synchronously when the second friction disc 26 rises and falls;

[0038] During operation, the chuck 17 is pulled upward, and the chuck 17 moves upward, driving the friction cylinder 16 and the second friction disk 26 to move upward through the mounting rod 15. The second friction disk 26 moves upward, driving the second friction ring 23 to move upward through the push-pull mechanism, until the right side of the friction cylinder 16 is no longer in contact with the first friction disk 14. At this time, the second friction disk 26 is in contact with the first friction disk 14 and transmits power to each other; when the motor 13 is started, the first friction disk 14 rotates, driving the second friction ring 23 to rotate through the second friction disk 26. The second friction ring 23 rotates, driving the connecting sleeve 22 to rotate through the lifting block 24 and the lifting slot 25. The connecting sleeve 22 rotates, driving the mounting ring 20 to rotate, so that when the motor 13 is started, it can only drive the mounting ring 20 to rotate and can no longer drive the mounting sleeve 10 to rotate, which brings convenience to the extrusion block 21 to squeeze the walking rod 7.

[0039] See also Figure 4 As a further solution of the present invention, the push-pull mechanism includes a lifting ring 27 fixedly installed on the outer side of the bottom end of the second friction ring 23, and a push-pull plate 28 is fixedly installed on the bottom end of the second friction plate 26. The top of the left end of the push-pull plate 28 fits with the bottom of the right end of the lifting ring 27, and the bottom of the left end of the second friction plate 26 fits with the top of the right end of the push-pull plate 28;

[0040] During operation, the second friction plate 26 moves upward to drive the push-pull plate 28 to move upward, and the push-pull plate 28 moves upward to push the second friction ring 23 to move upward. When the second friction plate 26 is reset, the second friction plate 26 moves downward to squeeze the second friction ring 23 to move downward, thereby realizing the synchronous lifting and lowering of the second friction plate 26 and the second friction ring 23.

[0041] See also Figure 5-Figure 6 As a further solution of the present invention, the synchronization mechanism includes support rods 29 fixedly installed at the bottoms of both left and right ends of the first friction ring 11, and the outer side of the support rods 29 is slidably connected with a lifting plate 30 through a compression spring, and the bottom ends of the lifting plates 30 are fixedly installed with locking blocks 31, and the outer side of the top of the connecting sleeve 22 is fixedly installed with a gear ring 32, and the bottom end of the locking block 31 is conical and passes through the gap inside the gear ring 32, and the top of the second friction ring 23 is fixedly installed with a push ring 33, and the diameter of the push ring 33 is larger than the maximum diameter of the gear ring 32;

[0042] During operation, the second friction ring 23 moves upward, driving the push ring 33 to move upward. During the upward movement of the push ring 33, the locking block 31 is squeezed. The locking block 31 is squeezed and pushes the lifting plate 30 to move upward until the locking block 31 is removed from the gap of the gear ring 32. At this time, the first friction ring 11 and the connecting sleeve 22 are in an unlocked state, and the rotation of the connecting sleeve 22 will not drive the installation sleeve 10 to rotate; when the adjustment of the walking rod 7 is completed, the second friction ring 23 and the push ring 33 move downward and no longer squeeze the locking block 31. At this time, the locking block 31 and the lifting plate 30 move upward under the push of the compression spring and are reinserted into the gap on the surface of the gear ring 32.

[0043] See also Figure 4 As a further solution of the present invention, a support plate 34 is fixedly mounted on the top of the mounting frame 12, and a tooth plate 35 is slidably connected to the right end of the support plate 34 through a compression spring, and the left end of the chuck 17 is located inside the groove of the tooth plate 35;

[0044] During operation, when the mounting rod 15 needs to be moved, the toothed plate 35 only needs to be pushed to the left. When the chuck 17 is removed from the groove on the toothed plate 35, the chuck 17 can be pulled upward to drive the mounting rod 15 to move upward. When the mounting rod 15 can no longer move upward, the toothed plate 35 only needs to be released. The toothed plate 35 moves toward the chuck 17 under the action of the compression spring until the chuck 17 is again limited by the groove on the surface of the toothed plate 35, so that the mounting rod 15 will not move up and down when the device is moved and adjusted, thereby ensuring the stable operation of the device.

[0045] See also Figure 7-Figure 8 As a further solution of the present invention, the switching mechanism includes a rotating rod 36 rotatably connected to the inner side of the mounting column 6, the bottom end of the rotating rod 36 is fixedly connected to the mounting plate 8, a mounting groove 37 is provided in the middle of the mounting column 6, the top end of the rotating rod 36 passes through the mounting groove 37 and is fixedly installed with a gear 38, a rack 39 is slidably connected to the inner side of the mounting groove 37, the gear 38 is meshed with the rack 39, the front end of the rack 39 extends out from the front end of the mounting groove 37, and a positioning mechanism is provided on the right side of the rack 39, the positioning mechanism is used to lock the rack 39, and unlock it when the rack 39 contacts the end of the track 4;

[0046] During operation, when the T-block 5 is about to move to the end of the track 4, the positioning mechanism unlocks and locks the rack 39, and the device continues to move so that the rack 39 is squeezed by the end of the track 4. The rack 39 is squeezed and slides in the mounting groove 37. At this time, the gear 38 drives the rotating rod 36 to rotate under the drive of the rack 39, and the rotating rod 36 rotates through the mounting plate 8 to drive the fill light 9 to rotate 180° around the mounting column 6. At this time, the fill light 9 flips to the other side of the device. In the process of the T-block 5 and the mounting column 6 moving to the initial position, the fill light 9 illuminates the line on the other side of the inner wall of the wiring trough 2. The staff only needs to move to the other side of the wiring trough 2 for observation, so that the staff can easily observe a group of lines in the wiring trough 2 in a comprehensive manner. Separate observation from both sides inside the wiring trough 2 avoids the occurrence of obstructions between the lines, so that each line inside the wiring trough 2 can be observed, further reducing omissions during fault inspection and maintenance.

[0048] During operation, when the T-shaped block 5 is about to move to the end of the track 4, one of the squeezing rods 40 is first squeezed by the end of the track 4, and the squeezing rod 40 is squeezed and moves along the rack 39 toward the positioning plate 41. At this time, the inclined surface of the positioning plate 41 is squeezed to make it move toward the rack 39, and the movement of the positioning plate 41 drives the positioning block 42 to move out of the positioning groove 43, thereby unlocking the rack 39; the rack 39 moves in the installation groove 37 and drives the positioning block 42 to move through the sliding rod 44 until the fill light 9 moves to the other side of the device. At this time, the positioning block 42 is aligned with the other positioning groove 43. When the device moves to the initial position, the squeezing rod 40 is no longer squeezed by the track 4, and the positioning plate 41, driven by the compression spring, pushes the positioning block 42 to insert into the other positioning groove 43, thereby re-locking the rack 39.
