Description

Technical Field

[0001] This invention belongs to the field of power construction equipment technology, and specifically relates to a power supply and distribution circuit switch cabinet paralleling device. Background Technology

[0002] Existing switchgear paralleling devices safely, reliably, and precisely connect and fix multiple independent switchgear into a single unit. However, in the process of paralleling multiple independent switchgear, it is necessary to first align multiple sets of switchgear sequentially before connecting the busbars between the switchgear.

[0003] A search revealed that Chinese Patent Publication No. CN118336572B, authorized on September 24, 2024, discloses a switchgear merging device, including a mobile cart and a mounting cover fixedly installed on its top. A hydraulic cylinder is fixedly inserted into the top of the mounting cover, and the extended end of the hydraulic cylinder is provided with a clamping mechanism for fixing the switchgear. A displacement mechanism for pushing the switchgear is provided on one side of the clamping mechanism. The top of the switchgear is fixedly clamped by the clamping arms and anti-slip blocks. The extended end of the hydraulic cylinder is controlled to continue to retract. At this time, the switchgear is lifted by the four clamping arms, making it easy for the switchgear to be manually placed on the support rail. The operator then pushes the mobile cart onto the support rail with the help of the handle. The operator moves the mobile cart to align with another switchgear located on the support rail. When the other switchgear is also in the groove, the push rod and push plate provide a pushing force to push the switchgear to be close to the other switchgear, making it easy for the operator to perform accurate merging and alignment operations.

[0004] However, the equipment still has the following defects: Although it can facilitate accurate manual operation of merging switch cabinets, in the actual process of merging multiple switch cabinets, the switch cabinets are heavier at the bottom and lighter at the top. The merging method in the above-mentioned cited document is to hold the top of the switch cabinet with the clamping arm and then swing it left and right. This can easily cause damage to the top shell of the merging switch cabinet after it is merging, and it can also cause the switch cabinet to be unable to move at the bottom, affecting the actual operation of merging switch cabinets. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a power distribution circuit switchgear paralleling device, comprising a storage plate; a storage groove is provided on one side wall of the storage plate, a paralleling assembly is fixedly connected to the top of the storage plate, and the inner cavity of the paralleling assembly is interconnected with the storage groove; two sets of guide components for assisting in paralleling switchgear in different positions are rotatably connected to the outer wall of the paralleling assembly near the opening; cylinders are also embedded on both sides of the outer wall of the paralleling assembly, and the output ends of the two sets of cylinders are drivenly connected to a linkage component for assisting in paralleling switchgear; and an upper component for assisting in paralleling switchgear is fitted to the inner wall of the paralleling assembly.

Two sets of magnetic adsorption blocks are fixedly connected to the inner wall of the cabinet shell near the opening.

[0008] Furthermore, both sets of magnetic adsorption blocks are magnetically adsorbed to the bottom end of the limiting plate. The inner wall of the cabinet housing is provided with three sets of hollow sliding cavities, and the three sets of hollow sliding cavities are located on different inner walls of the cabinet housing. A servo motor is embedded at the top of the inner wall of each of the three sets of hollow sliding cavities, and the output end of each servo motor is connected to a first lead screw.

[0009] Furthermore, the guide assembly includes a storage cover; one end of the storage cover is an open structure, and guide grooves are provided on both the upper and lower sides of the inner wall of the storage cover. Two sets of hinge seats are fixedly connected to the end of the storage cover and the side near the opening.

[0010] Furthermore, both sets of hinge seats and the inner walls of the guide groove are slidably connected to movable plates. A traction shaft is fixedly connected to the other side of the top of the movable plate. A linkage sleeve is rotatably connected to the traction shaft, and a second lead screw is fixedly connected to the outer wall of the linkage sleeve. A shaft pin is rotatably connected to the top of the storage cover on the side away from the opening.

[0011] Furthermore, a bearing is fixedly connected to the shaft pin, an internally threaded cylinder is rotatably connected to one side wall of the bearing, and the other end of the internally threaded cylinder is threadedly connected to the second lead screw. Several sets of guide rollers are rotatably connected to the outer wall of the movable plate.

[0012] Furthermore, the linkage component includes two sets of clamping plates; the inner sidewalls of one end of each set of clamping plates are provided with a feeding ramp, and guide grooves are provided on each set of clamping plates; a positioning block is fixedly connected to the top of each set of clamping plates and the end closest to the feeding ramp; a stepper motor is fixedly connected to the top of each set of clamping plates and the end furthest from the feeding ramp; and a third lead screw is driven between the output end of the stepper motor and one side wall of the positioning block.

[0013] Furthermore, a linkage block is threaded onto the third lead screw, and the linkage block is slidably attached to the top of the clamping plate. A linkage rod is fixedly connected to the bottom end of the linkage block, and the linkage rod is slidably attached to the inner wall of the guide groove. Air supply pipes are fixedly connected to the top ends of both sets of linkage blocks, and air pumps are installed on both sets of air supply pipes. Air outlet pipes are sleeved at the ends of both sets of air supply pipes, and several sets of exhaust holes are opened at the bottom of the exhaust pipes. An LED light is also embedded in the outer wall of the exhaust pipe on the side away from the several sets of exhaust holes.

[0014] Furthermore, the upper-level component includes a right-angled trapezoidal housing; a rectangular housing is fixedly connected to one side wall of the right-angled trapezoidal housing; the bottoms of both the rectangular housing and the right-angled trapezoidal housing are hollowed-out structures; a linkage slider is fixedly connected to both side walls of the right-angled trapezoidal housing and one side wall of the rectangular housing; the linkage slider has an internal threaded hole, and the internal threaded hole is threadedly connected to the first lead screw of the cabinet assembly; several sets of first guide rollers are rotatably connected to the top of the right-angled trapezoidal housing in an inclined position; several sets of second guide rollers are rotatably connected to the top of the rectangular housing in a horizontal position; positioning screws penetrate the inner walls of both the rectangular housing and the right-angled trapezoidal housing, and one end of the positioning screw is threadedly connected to the outer wall of the linkage slider.

[0015] The beneficial effects of this invention are:

[0016] 1. After the guide components on both sides are extended, the range of the switchgear entering the parallel assembly is expanded. The fan-shaped guide components on both sides push the switchgear to one end of the upper component, which facilitates the continuous pushing of the switchgear. The two sets of switchgear that need to be paralleled are moved into the parallel assembly in sequence. Then, the cylinders on both sides push the linkage component, so that the linkage component docks with the two sides of the switchgear. Then, the upper component slides up and down on the inner wall of the parallel assembly, so that the two sets of switchgear are in contact with each other before paralleling, which improves the stability and safety of the parallel connection of switchgear.

[0017] 2. The output of the servo motor drives the first lead screw to rotate, causing the linkage slider on the threaded connection of the first lead screw to rise and fall. This is used to move the first guide roller and the second guide roller to a position close to the horizontal ground. Utilizing the inclined design of one side wall of the right-angled trapezoidal housing, the bottom of the switch cabinets that need to be paralleled are moved sequentially into the paralleling cabinet housing by the first guide roller and the second guide roller. The feeding inclined surface between the two sets of clamping plates reduces the risk of collision between the switch cabinets and the paralleling cabinet housing, allowing the paralleling cabinet housing to enter the paralleling cabinet housing horizontally.

[0018] 3. The output end of the cylinder pushes the outer wall of the clamping plate, causing the clamping plate to contact the outer wall of the switchgear as they approach each other. This ensures that the switchgear entering the parallel cabinet housing is in a state of horizontal bottom and side wall alignment. Then, the output end of the stepper motor drives the third lead screw to rotate continuously, causing the air outlet pipe to move horizontally to the top gap between the two sets of switchgear after alignment. The air pump continuously outputs airflow through the exhaust hole to blow downwards to the busbar connection bar between each pair of switchgear, automatically cleaning the busbar connection surface to remove oxide layer, dust, and oil. If necessary, the gap between the two sets of switchgear placed horizontally at the top can be adjusted using the horizontally set second guide roller, so that the two sets of switchgear roll into contact with the second guide roller. After widening the gap between the two sets of switchgear, if necessary, use fine sandpaper to lightly sand and apply conductive paste to improve the parallel cabinet energizing efficiency of the busbar connection bar between the switchgear.

[0019] 4. After the two sets of switch cabinets come into rolling contact with the second guide roller, the gap between the two sets of switch cabinets can be easily adjusted. After the two sets of switch cabinets are combined, the limit plate is flipped to one side to open the top of the combined cabinet housing. Then, the two sets of switch cabinets after being combined are pushed to move downwards to the other side opening of the combined cabinet housing by the second guide roller and the first guide roller, which facilitates the unloading operation of the combined switch cabinets.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] This invention provides a parallel cabinet device for power supply and distribution circuit switchgear, including a storage plate 1; exemplarily, such as... Figure 1 and Figure 2 As shown.

[0034] The storage plate 1 has a storage groove on one side wall. The top of the storage plate 1 is fixedly connected to the cabinet merging assembly 2, and the inner cavity of the cabinet merging assembly 2 is connected to the storage groove. The outer wall of the cabinet merging assembly 2 and the side near the opening are rotatably connected to two sets of guide assemblies 3 for assisting in merging switch cabinets in different positions. Cylinders 5 are also embedded on both sides of the outer wall of the cabinet merging assembly 2, and the output ends of the two sets of cylinders 5 are drivenly connected to a linkage assembly 6 for assisting in merging switch cabinets. The inner wall of the cabinet merging assembly 2 is fitted with an upper assembly 7 for assisting in merging switch cabinets.

[0035] Furthermore, universal casters are provided at the bottom corners of the storage board 1, and a ladder 4 is fixedly connected between the outer wall of the cabinet assembly 2 and the side wall away from the opening and the top of the storage board 1.

[0036] Specifically, after the guide components 3 on both sides are extended, they are used to expand the range of the switch cabinet entering the parallel cabinet assembly 2. The fan-shaped guide components 3 on both sides push the switch cabinet to one end of the upper assembly 7, which facilitates the continuous pushing of the switch cabinet. The two sets of switch cabinets that need to be paralleled are moved into the parallel cabinet assembly 2 in sequence. Then, the cylinders 5 on both sides push the linkage component 6, so that the linkage component 6 docks with the two sides of the switch cabinet. Then, the upper assembly 7 is used to slide up and down on the inner wall of the parallel cabinet assembly 2, so that the two sets of switch cabinets are in contact with each other before paralleling.

[0037] The cabinet assembly 2 includes a cabinet housing 21; for example, such as Figure 3 , Figure 4 and Figure 5 As shown.

[0038] The cabinet housing 21 has an open structure on one side wall and top. A limiting plate 22 is rotatably connected to one side of the top of the cabinet housing 21. An inspection port 23 is provided on the outer wall of the limiting plate 22. A limiting groove 24 is provided on one side of the inner wall of the inspection port 23. An inspection cover 25 is horizontally connected through one side wall of the limiting plate 22. One end of the inspection cover 25 extends to the inner wall of the limiting groove 24. Two sets of magnetic adsorption blocks 26 are fixedly connected to the inner wall of the cabinet housing 21 near the opening. Both sets of magnetic adsorption blocks 26 are magnetically adsorbed to the bottom end of the limiting plate 22. Three sets of hollow sliding cavities 27 are provided on the inner wall of the cabinet housing 21. The three sets of hollow sliding cavities 27 are located on different inner walls of the cabinet housing 21. A servo motor 28 is embedded at the top of the inner wall of each of the three sets of hollow sliding cavities 27. The output end of each servo motor 28 is driven by a first lead screw 29.

[0039] The guide component 3 includes a storage cover 31; for example, such as Figure 6 As shown.

[0040] One end of the storage cover 31 is an open structure, and guide grooves 32 are provided on both the upper and lower sides of the inner wall of the storage cover 31. Two sets of hinge seats 33 are fixedly connected to the end of the storage cover 31 and the side near the opening. Movable plates 34 are slidably connected to the inner walls of the two sets of hinge seats 33 and the guide grooves 32. A traction shaft 36 is fixedly connected to the other side of the top of the movable plate 34. A linkage sleeve 37 is rotatably connected to the traction shaft 36, and a second lead screw 38 is fixedly connected to the outer wall of the linkage sleeve 37. A shaft pin 39 is rotatably connected to the top of the storage cover 31 and the side away from the opening. A bearing 310 is fixedly connected to the shaft pin 39. An internal threaded cylinder 311 is rotatably connected to one side wall of the bearing 310, and the other end of the internal threaded cylinder 311 is threadedly connected to the second lead screw 38. Several sets of guide rollers 35 are rotatably connected to the outer wall of the movable plate 34.

[0041] Furthermore, both sets of hinge seats 33 are interconnected with the guide groove 32.

[0042] Specifically, during the rotation of the two sets of internal threaded cylinders 311, the second lead screw 38 separates from the internal threaded cylinder 311, causing the movable plate 34 to separate from the storage cover 31. When one end of the two sets of movable plates 34 moves into the hinge seat 33, during the continuous rotation of the internal threaded cylinder 311, one end of the movable plate 34 rotates within the hinge seat 33 to change the guide surface of several sets of guide rollers 35 on the movable plate 34, which facilitates the auxiliary merging of the switch cabinets between the two movable plates 34.

[0043] The linkage component 6 includes two sets of clamping plates 61; for example, such as Figure 7 As shown.

[0044] Both sets of clamping plates 61 have an inner wall with a feeding ramp 62 at one end. Both sets of clamping plates 61 have guide grooves 63. A positioning block 64 is fixedly connected to the top of each clamping plate 61 near the feeding ramp 62. A stepper motor 65 is fixedly connected to the top of each clamping plate 61 away from the feeding ramp 62. A third lead screw 66 is connected between the output end of the stepper motor 65 and one side wall of the positioning block 64. A linkage block 67 is threaded onto the third lead screw 66, and the linkage block 67 slides against the wall. The linkage block 67 is connected to the top of the clamping plate 61. The bottom end of the linkage block 67 is fixedly connected to the linkage rod 68, and the linkage rod 68 is slidably attached to the inner wall of the guide groove 63. The top ends of the two sets of linkage blocks 67 are fixedly connected to the air supply pipes 69, and the two sets of air supply pipes 69 are equipped with air pumps. The ends of the two sets of air supply pipes 69 are sleeved with air outlet pipes 610, and the bottom of the air outlet pipes 610 is provided with several sets of exhaust holes 611. An LED light is also embedded in the outer wall of the air outlet pipes 610 on the side away from the several sets of exhaust holes 611.

[0045] Specifically, the output end of the cylinder 5 pushes the outer wall of the clamping plate 61, so that the clamping plate 61 contacts the outer wall of the switch cabinet as they approach each other. This is used to place the switch cabinets entering the parallel cabinet housing 21 in a state of bottom horizontal docking and side wall horizontal docking. Then, the output end of the stepper motor 65 drives the third lead screw 66 to rotate continuously, so that the air outlet pipe 610 moves horizontally to the top gap of the two sets of switch cabinets after docking. The air pump continuously outputs airflow through the exhaust hole 611 to blow it downward to the busbar connection bar between each pair of switch cabinets, which is used to automatically clean the surface of the busbar connection bar, removing oxide layer, dust and oil stains.

[0046] The upper component 7 includes a right-angled trapezoidal housing 71; for example, such as Figure 8 and Figure 9 As shown.

[0047] A rectangular shell 72 is fixedly connected to one side wall of the right-angled trapezoidal shell 71. The bottom of both the rectangular shell 72 and the right-angled trapezoidal shell 71 has a hollow structure. A linkage slider 73 is fixedly connected to both side walls of the right-angled trapezoidal shell 71 and one side wall of the rectangular shell 72. The linkage slider 73 has an internal threaded hole 74, which is threaded to the first lead screw 29 of the cabinet assembly 2. Several sets of first guide rollers 75 are rotatably connected to the top of the right-angled trapezoidal shell 71 in an inclined position. Several sets of second guide rollers 76 are rotatably connected to the top of the rectangular shell 72 in a horizontal position. A positioning screw 77 passes through the inner wall of both the rectangular shell 72 and the right-angled trapezoidal shell 71, and one end of the positioning screw 77 is threaded to the outer wall of the linkage slider 73.

[0048] Specifically, the output end of the servo motor 28 drives the first lead screw 29 to rotate, causing the linkage slider 73 on the threaded connection of the first lead screw 29 to rise and fall, which is used to move the first guide roller 75 and the second guide roller 76 to a position close to the horizontal ground. Utilizing the inclined surface design of one side wall of the right-angled trapezoidal housing 71, the bottom of the switch cabinets that need to be paralleled is moved sequentially through the first guide roller 75 and the second guide roller 76 into the paralleling housing 21. The loading inclined surface 62 between the two sets of clamping plates 61 reduces the risk of collision between the switch cabinets and the paralleling housing 21, allowing the paralleling housing 21 to enter horizontally.

[0049] If necessary, the gap between the two sets of switch cabinets placed horizontally at the top can be adjusted using the horizontally set second guide roller 76, so that the two sets of switch cabinets roll into contact with the second guide roller 76. After widening the gap between the two sets of switch cabinets, if necessary, use fine sandpaper to lightly polish and apply conductive paste to improve the parallel power-on efficiency of the busbar connection between the switch cabinets.

[0050] After the two sets of switch cabinets roll into contact with the second guide roller 76, the gap between the two sets of switch cabinets can be easily adjusted. After the two sets of switch cabinets are combined, the limiting plate 22 is flipped to one side to open the top of the combined cabinet housing 21. Then, the two sets of switch cabinets after being combined are pushed so that they move downwards from the second guide roller 76 and the first guide roller 75 to the opening on the other side of the combined cabinet housing 21, which facilitates the unloading operation of the switch cabinets after being combined.

[0051] The working principle of the power supply and distribution circuit switchgear paralleling device proposed in the embodiments of the present invention is as follows:

[0052] During the rotation of the two sets of internal threaded cylinders 311, the second lead screw 38 is separated from the internal threaded cylinder 311, which drives the movable plate 34 to separate from the storage cover 31. When one end of the two sets of movable plates 34 moves into the hinge seat 33, during the continuous rotation of the internal threaded cylinder 311, one end of the movable plate 34 rotates within the hinge seat 33 to change the guide surface of several sets of guide rollers 35 on the movable plate 34, so as to facilitate the auxiliary paralleling of the switch cabinet between the two movable plates 34.

[0053] The output of the servo motor 28 drives the first lead screw 29 to rotate, causing the linkage slider 73 on the threaded connection of the first lead screw 29 to rise and fall. This is used to move the first guide roller 75 and the second guide roller 76 to a position close to the horizontal ground. Utilizing the inclined design of one side wall of the right-angled trapezoidal housing 71, the bottom of the switch cabinets that need to be paralleled is moved sequentially through the first guide roller 75 and the second guide roller 76 into the paralleling housing 21. The feeding inclined surface 62 between the two sets of clamping plates 61 reduces the risk of collision between the switch cabinets and the paralleling housing 21, allowing the paralleling housing 21 to enter horizontally.

[0054] The output end of the cylinder 5 pushes the outer wall of the clamping plate 61, so that the clamping plate 61 contacts the outer wall of the switch cabinet as they approach each other. This is used to put the switch cabinets that have entered the parallel cabinet housing 21 into a state of horizontal bottom and side wall docking. Then, the output end of the stepper motor 65 drives the third lead screw 66 to rotate continuously, so that the air outlet pipe 610 moves horizontally to the top gap of the two sets of switch cabinets after docking. The air pump continuously outputs airflow through the exhaust hole 611 to blow it downward to the busbar connection bar between each pair of switch cabinets. This is used to automatically clean the surface of the busbar connection bar, removing oxide layer, dust and oil. If necessary, the horizontally set second guide roller 76 can be used to adjust the gap between the two sets of switch cabinets placed horizontally at the top, so that the two sets of switch cabinets roll in contact with the second guide roller 76. After widening the gap between the two sets of switch cabinets, if necessary, use fine sandpaper to lightly polish and apply conductive paste to improve the parallel cabinet power supply efficiency of the busbar connection bar between the switch cabinets.

[0055] After the two sets of switch cabinets roll into contact with the second guide roller 76, the gap between the two sets of switch cabinets can be easily adjusted. After the two sets of switch cabinets are combined, the limiting plate 22 is flipped to one side to open the top of the combined cabinet housing 21. Then, the two sets of switch cabinets after being combined are pushed so that they move downwards from the second guide roller 76 and the first guide roller 75 to the opening on the other side of the combined cabinet housing 21, which facilitates the unloading operation of the switch cabinets after being combined.

[0056] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
