Description

Technical Field

[0001] This invention relates to the field of power distribution equipment technology, and in particular to power module assembly equipment. Background Technology

[0002] Switchgear is a type of electrical equipment widely used in power systems. It is mainly used for opening, closing, controlling and protecting electrical equipment during power generation, transmission, distribution and power conversion. Switchgear integrates circuit breakers, disconnect switches, load switches, instrument transformers and various protection devices and control modules, and is a key node to ensure the safe and stable operation of the power system.

[0003] Traditional switchgear installation involves transporting the empty cabinet to the site and then installing and wiring the internal components on-site. This method is not only time-consuming but also highly susceptible to the influence of the site environment, making it difficult to guarantee the installation and debugging quality of the electronic modules. In contrast, the power module assembly equipment pre-assembles and finely debugs the switchgear and all internal electronic modules in the factory, forming a complete unit before transporting it to the construction site. This significantly shortens the on-site construction cycle, reduces on-site workload, and ensures that the internal components of the equipment are in optimal working condition.

[0004] However, existing power module assembly equipment requires the first step of pouring or fixing a load-bearing foundation on the ground. Then, the switchgear is hoisted onto the foundation using lifting equipment, and finally secured with bolts or welding. This installation method demands precise alignment between the mounting holes on the bottom of the switchgear and the pre-drilled holes in the foundation. Due to the large weight of the assembly equipment, the massive cabinet experiences inertial swaying during hoisting, making fine-tuning extremely difficult. This results in time-consuming and labor-intensive alignment of the mounting holes, and repeated hoisting and adjustments can damage the equipment or the foundation surface. To address these issues, existing technology uses an external pressure plate to hold the bottom edge of the cabinet in place after it has been positioned, and then screws are used to lock the pressure plate to the foundation. While this method reduces the precision requirements for the holes, the external pressure plate occupies installation space, and installers need to perform tedious screw tightening work around the bottom of the cabinet. Installers also need to open the cabinet door to operate inside, allowing external dust and moisture to enter the already cleaned cabinet, making operation inconvenient and reducing the practicality of the power module assembly equipment. Summary of the Invention

[0005] The purpose of this invention is to provide a power module assembly device that solves the problems of existing power module assembly devices, which require precise hole alignment during hoisting and fixing, which is time-consuming and labor-intensive, and the bolt fixing method requires tedious manual work, which may damage the internal sealing environment of the cabinet or the surface anti-corrosion layer, resulting in damage or rust to the electronic modules.

[0007] Through the above technical solution, the switchgear is automatically locked and fixed by using its own weight to press the elastic contact block during hoisting.

[0008] Preferably, the sealing mechanism includes a hollow plate, which is fixedly connected to the inner left side of the load-bearing foundation. A silicone capsule sleeve is fixedly connected to the inner left side of the base plate. The outer side of the silicone capsule sleeve penetrates the hollow plate.

A pressing block is fixedly connected to the left end of the plug-in post. The pressing block is in contact with the silicone capsule sleeve.

[0009] Through the above technical solution, the rotating threaded rod drives the movable disk to rotate via rack and pinion transmission, which in turn pushes the extrusion block to radially shrink and extrude the silicone capsule sleeve, thereby achieving cable sealing.

[0010] Preferably, the splicing mechanism includes a hollow disk, which is disposed on the right side of the switch cabinet. Wedge-shaped blocks are fixedly connected to the front and rear sides of the right wall of the hollow disk. Slots are provided on the outer side of the wedge-shaped blocks. Windows are provided on the upper and lower sides of the right wall of the hollow disk. A movable rod is rotatably connected inside the hollow disk. A support plate is fixedly connected to the right end of the outer wall of the movable rod. Wedge-shaped blocks are fixedly connected to the upper and lower ends of the support plate.

[0011] The above technical solution utilizes the cooperation of wedge-shaped inserts and wedge-shaped locking blocks to achieve automatic locking, and the support plate resets and locks the connection, thus completing the rapid splicing of the switch cabinets on both sides.

[0012] Preferably, the installation mechanism further includes two guide rods, which are fixedly connected to the left and right sides of the inside of the base plate, respectively. The outer side of the guide rod is slidably connected to the support plate, and a return spring is provided on the upper side of the outer wall of the guide rod.

[0013] Through the above technical solution, the guide rod restricts the movement trajectory of the support plate, and the return spring provides a reverse elastic force to assist the mechanism in resetting.

[0014] Preferably, the sealing mechanism further includes a fixing rod, which is fixedly connected to the left side of the bottom inner end of the hollow plate, and the outer side of the fixing rod is slidably connected to the straight rack.

[0015] The above technical solution guides and limits the movement of the spur rack by using a fixed rod.

[0016] Preferably, the sealing mechanism further includes multiple sliding grooves, which are equidistantly formed on the inside right side of the hollow plate, and the extrusion block is slidably connected to the sliding grooves.

[0017] Through the above technical solution, the chute can limit the radial movement trajectory of the extrusion block, so that the extrusion block will not deviate when moving.

[0018] Preferably, the splicing mechanism further includes a torsion spring, which is disposed on the outside of the movable rod. The left and right ends of the torsion spring are fixedly connected to the inner wall of the hollow disk and the left side of the support plate, respectively. The left end of the movable rod passes through the hollow disk, and a stop block is fixedly connected to the upper inside of the hollow disk. The stop block is in contact with the support plate.

[0019] Through the above technical solution, the torsion spring provides power for the support plate to reset, and the stop block limits the rotation angle of the support plate.

[0021] The above technical solution facilitates internal maintenance through the cabinet door, and allows cables to be inserted through the wiring hole.

[0022] Preferably, the splicing mechanism further includes two screws, which are threaded to the front and rear ends of the right side of the hollow disk, respectively, and the left end of the screws passes through the hollow disk and is threaded to the switch cabinet.

[0023] The above technical solution enables the fixing and disassembly of the hollow disc through screw connection, facilitating its use.

[0024] Preferably, the splicing mechanism further includes a connecting port, which is located on the right side of the switch cabinet, and a sealing ring is fixedly connected to the right side of the switch cabinet.

[0025] The above technical solution enables internal communication within the cabinet through the connecting port, while the sealing ring ensures the sealing performance at the joints.

[0026] In summary, the present invention has at least one of the following beneficial technical effects: 1. This invention utilizes the weight of the switch cabinet itself to bring the base plate into contact with the load-bearing foundation, forcing the elastic contact block to move upward relative to the base plate. This, in turn, drives the support plate to overcome the resistance of the return spring and slide upward along the guide rod. As the support plate slides upward, it pulls the claws to rotate through the connecting plate, causing the claws to automatically engage in the slots at the top of the load-bearing foundation. This achieves automatic locking and fixing using its own weight, eliminating the need for manual operation of the holes and inside the cabinet, thus ensuring the safety and cleanliness of the internal electronic modules.

[0027] 2. This invention drives a straight rack to move via a rotating threaded rod, which in turn drives a movable disc to rotate via an arc-shaped rack. The curved groove on the movable disc drives multiple plug-in pins to move the extrusion block synchronously radially and centripetally within the slide groove, thereby uniformly extruding the silicone bladder sleeve. This ensures that the extrusion block fits tightly against the cable surface, eliminating gaps between the silicone bladder sleeve and the cable. This effectively prevents small animals or moisture from entering the switch cabinet through the wiring hole. Furthermore, the stroke adjustment of the extrusion block can accommodate the sealing requirements of cables with various diameters.

[0028] 3. When the switch cabinets on both sides are spliced ​​close to each other, the wedge-shaped plug is inserted into the window of the hollow plate. The wedge surface contacts and pushes the wedge-shaped block to drive the support plate to rotate and avoid it. When it is inserted into place, the support plate reverses and resets under the action of the torsion spring, so that the wedge-shaped block is locked into the slot on the wedge-shaped plug, realizing the quick and automatic locking splicing of the switch cabinets on both sides, making the splicing work more convenient and faster.

[0031] The following is in conjunction with the appendix Figure 1 -Appendix Figure 9 The present invention will be further described in detail below.

[0032] The present invention provides a power module assembly equipment, including a switch cabinet 1, a base plate 5 fixedly connected to the bottom of the switch cabinet 1, a load-bearing foundation 6 provided on the lower side of the base plate 5, an installation mechanism 2 provided on the inner side of the base plate 5, a sealing mechanism 3 provided inside the load-bearing foundation 6, and a splicing mechanism 4 provided on the right side of the switch cabinet 1. The mounting mechanism 2 includes a support plate 21, which is located inside the base plate 5. Claws 22 are rotatably connected to the bottom perimeter of the inner side of the base plate 5. Connecting plates 23 are fixedly connected to the upper sides of the claws 22. The top of the connecting plates 23 is rotatably connected to the support plate 21. When the support plate 21 moves, the connecting plates 23 drive the claws 22 to rotate. The top perimeter of the load-bearing foundation 6 is provided with slots 24. The bottom of the connecting plates 23 penetrates the base plate 5 and engages with the slots 24. An elastic contact block 25 is fixedly connected to the bottom of the support plate 21, and the bottom of the elastic contact block 25 penetrates the base plate 5. The elastic contact block 25 can push the support plate 21 to rotate. The top of the base plate 5 is threaded with a bolt 26. The bottom of the bolt 26 passes through the base plate 5 and abuts against the support plate 21. Rotating the bolt 26 can push the support plate 21 to move downward. The mounting mechanism 2 also includes two guide rods 27. The two guide rods 27 are fixedly connected to the left and right sides inside the base plate 5 respectively. The outer side of the guide rod 27 is slidably connected to the support plate 21. The support plate 21 can slide on the outer side of the guide rod 27. A return spring 28 is provided on the upper side of the outer wall of the guide rod 27. The return spring 28 can push the support plate 21 to return to its original position. Specifically, when using the power supply assembly equipment for construction, the load-bearing foundation 6 is prefabricated according to the design dimensions and overall weight of the switchgear 1. The assembly and system debugging of the internal electronic modules of the switchgear 1 are completed in advance at the factory, and the integrated module is then transported to the construction site. During on-site operation, the switchgear 1 is hoisted above the pre-set load-bearing foundation 6. In the hoisted but not yet lowered state, the return spring 28 releases its elastic force to push the support plate 21 to slide downward along the outer wall of the guide rod 27, forcing the elastic contact block 25 to protrude from the bottom surface of the base plate 5. As the switchgear is lowered, the base plate 5 contacts the load-bearing foundation 6, and the switchgear 1 presses down with its own weight, causing the elastic contact block 25 to be stressed and return upward relative to the switchgear 1. The support plate 21 is pushed upward along the guide rod 27 in a synchronous manner. The upward displacement of the support plate 21 is converted into a pulling force through the connecting plate 23, which drives the bottom claw 22 to rotate. This causes the end of the claw 22 to engage with the slot 24 reserved at the top of the load-bearing foundation 6. The mechanical fixation between the base plate 5 and the load-bearing foundation 6 is achieved by using the gravity self-locking principle, thus completing the installation of the switch cabinet 1. If it needs to be removed or moved later, the bolt 26 is rotated so that the bolt 26 is screwed into the base plate 5 and presses the support plate 21 downward. This overcomes the resistance of the return spring 28 and compresses the elastic contact block 25, forcing the connecting plate 23 to push the claw 22 in the opposite direction to rotate out of the slot 24, releasing the mechanical lock, and the switch cabinet 1 can be lifted away.

[0033] The sealing mechanism 3 includes a hollow plate 31, which is fixedly connected to the inner left side of the load-bearing foundation 6. A silicone bladder sleeve 32 is fixedly connected to the inner left side of the base plate 5, and the outer side of the silicone bladder sleeve 32 penetrates the hollow plate 31. The silicone bladder sleeve 32 can seal the inserted cable. A movable disk 33 is rotatably connected to the inner right side of the hollow plate 31. A threaded rod 35 is rotatably connected to the inner bottom of the hollow plate 31, and the front end of the threaded rod 35 penetrates the hollow plate 31. A straight rack 36 is threadedly connected to the outer side of the threaded rod 35. Rotation of the threaded rod 35 drives the straight rack 36 to move. An arc-shaped rack 37 is fixedly connected to the bottom of the movable disk 33. The arc-shaped rack 37 meshes with the straight rack 36. When the straight rack 36 moves, the arc-shaped rack 37 can drive the movable disk 33 to rotate. Multiple curved grooves 34 are equidistantly opened on the outer side of the movable disk 33. The inner side of the curved groove 34 is slidably connected to the insertion post 38. When the movable disk 33 rotates, the insertion post 38 can be pushed to move through the curved groove 34. The left end of the insertion post 38 is fixedly connected to the extrusion block 39. The extrusion block 39 contacts the silicone capsule sleeve 32. The insertion post 38 will push the extrusion block 39 to move, thereby extruding the silicone capsule sleeve 32. The sealing mechanism 3 also includes a fixing rod 310. The fixing rod 310 is fixedly connected to the left side of the bottom end of the hollow plate 31. The outer side of the fixing rod 310 is slidably connected to the straight rack 36. The straight rack 36 can slide on the outer side of the fixing rod 310 and is guided by the fixing rod 310. The sealing mechanism 3 also includes multiple sliding grooves 311. Multiple sliding grooves 311 are equidistantly opened on the right side of the hollow plate 31. The extrusion block 39 is slidably connected to the sliding groove 311. The sliding groove 311 can provide movement guidance for the extrusion block 39. Specifically, during the cable introduction process, the external cable first passes through the silicon capsule sleeve 32 pre-placed in the load-bearing foundation 6, and is introduced into the wiring position inside the switch cabinet 1 through the cable hole 7. After the cable is laid, the threaded rod 35 is rotated, and the threaded rod 35 drives the rack 36 to move. Since the rack 36 meshes with the arc-shaped rack 37 on the outer edge of the movable disk 33, the linear motion of the rack 36 is converted into the circumferential rotation of the movable disk 33. During the rotation, the movable disk 33 applies a guiding force to the plug-in post 38 through the curved groove 34. This forces the plug-in post 38 to drive the front end extrusion block 39 to slide within the slide groove 311. As the rotation angle of the movable disk 33 increases, multiple extrusion blocks 39 synchronously feed radially towards the center under the constraint of the slide groove 311, applying centripetal extrusion force to the central silicon capsule sleeve 32. This causes the silicon capsule sleeve 32 to undergo elastic deformation and tightly fit the outer wall of the cable, eliminating the mating gap and forming a sealing layer to block the path of small animals or water vapor to enter the switch cabinet 1. Moreover, this multi-directional synchronous extrusion mechanism allows the silicon capsule sleeve 32 to adapt to the sealing requirements of cables with different wire diameters.

[0034] The splicing mechanism 4 includes a hollow disk 41, which is located on the right side of the switch cabinet 1. Wedge-shaped blocks 42 are fixedly connected to the front and rear sides of the right wall of the hollow disk 41. Slots 43 are provided on the outer sides of the wedge-shaped blocks 42. Windows 44 are provided on the upper and lower sides of the right wall of the hollow disk 41, allowing the wedge-shaped blocks 42 to be inserted into the corresponding windows 44. A movable rod 45 is rotatably connected inside the hollow disk 41. A support plate 46 is fixedly connected to the right end of the outer wall of the movable rod 45. Wedge-shaped locking blocks 47 are fixedly connected to the upper and lower ends of the support plate 46, allowing the wedge-shaped locking blocks 47 to engage with the slots 43 on the wedge-shaped blocks 42. The splicing mechanism 4 also includes a torsion spring 48. Spring 48 is set on the outside of movable rod 45. The left and right ends of torsion spring 48 are fixedly connected to the inner wall of hollow disk 41 and the left side of support plate 46, respectively. Torsion spring 48 can pull support plate 46 to rotate and reset. The left end of movable rod 45 passes through hollow disk 41. A stop block 49 is fixedly connected to the upper inside of hollow disk 41. The stop block 49 is in contact with support plate 46. The stop block 49 restricts the rotation angle of support plate 46. The splicing mechanism 4 also includes a connecting port 411. The connecting port 411 is opened on the right side of switch cabinet 1. A sealing ring 412 is fixedly connected to the right side of switch cabinet 1. The sealing ring 412 prevents dust and moisture from entering the interior of switch cabinet 1 through connecting port 411. Specifically, when multiple switchgear 1 units need to be connected in parallel, the switchgear 1 units on both sides are brought closer together, so that the hollow panels 41 fixed on the sides are aligned and fitted together. During this process, the wedge-shaped plug 42 on one side is aligned with and inserted into the window 44 of the hollow panel 41 on the other side. The inclined surface of the front end of the wedge-shaped plug 42 abuts against the inclined surface of the internal wedge-shaped locking block 47. The wedge-shaped plug 42 is guided and pushed to move laterally, causing the support plate 46 to deflect and move against the torque of the torsion spring 48. When the wedge-shaped plug 42 is fully inserted, the slot 43 moves to the position where the wedge-shaped locking block 47 is aligned. When the position is correct, the support plate 46 quickly resets under the rebound force of the torsion spring 48, driving the wedge-shaped locking block 47 to embed into the slot 43, thereby achieving longitudinal limiting and locking of the wedge-shaped plug 42 and completing the mechanical splicing between the cabinets. At this time, the side connection port 411 is aligned and connected, and the sealing ring 412 is deformed under pressure to ensure the dustproof and waterproof performance of the interface. If it is necessary to separate the cabinets, rotate the external movable rod 45 to directly drive the support plate 46 to deflect, pull the wedge-shaped locking block 47 out of the slot 43, release the locking constraint on the wedge-shaped plug 42, and then the two switch cabinets 1 can be separated horizontally.

[0035] A door 8 is rotatably connected to the front side of the load-bearing foundation 6. A door lock 9 is provided on the right side of the front wall of the door 8. A wire hole 7 is provided on the rear side of the top of the load-bearing foundation 6. The wire hole 7 is connected to the inside of the switch cabinet 1. Specifically, by opening the door lock 9, the cabinet door 8 can be opened conveniently, which facilitates subsequent inspection and maintenance of the inner side of the load-bearing foundation 6 and the bottom of the switch cabinet 1. Cables can be easily threaded into the switch cabinet 1 through the cable hole 7.

[0036] The splicing mechanism 4 also includes two screws 410, which are threaded to the front and rear ends of the right side of the hollow disk 41 respectively, and the left end of the screw 410 passes through the hollow disk 41 and is threaded to the switch cabinet 1. Specifically, when there is no need to assemble the switch cabinet 1, the hollow panel 41 can be removed by unscrewing the screws 410.

[0037] Working principle: When using the power supply assembly equipment, a load-bearing foundation 6 is first constructed according to the length, width, height, and weight of the switch cabinet 1. All necessary electronic modules inside the switch cabinet 1 are installed and tested in the factory. After the entire cabinet is transported to the site, the switch cabinet 1 is hoisted onto the fixed load-bearing foundation 6. Before installation, the return spring 28 pushes the support plate 21 downwards on the outside of the guide rod 27, thereby causing the elastic contact block 25 to extend out from the bottom of the base plate 5. During hoisting, the base plate 5 contacts the load-bearing foundation 6 and moves upwards relative to the switch cabinet 1 as it descends. This will cause the support plate 21 to move upward. When the support plate 21 moves, it can drive the claw 22 to rotate through the connecting plate 23, so that the claw 22 can be engaged in the slot 24 at the top of the load-bearing foundation 6, thus fixing the base plate 5 to the load-bearing foundation 6 firmly, thereby completing the installation of the switch cabinet 1. When it is necessary to disassemble the switch cabinet 1, rotate the bolt 26. When the bolt 26 rotates, it will be screwed into the base plate 5, thereby pushing the support plate 21 to move downward and compress the elastic contact block 25, thereby driving the claw 22 to rotate and reset, thus releasing the relative fixation between the base plate 5 and the load-bearing foundation 6, and thus disassembling the switch cabinet 1. Furthermore, during the cable insertion process, the cable is first inserted into the load-bearing foundation 6 through the silicone capsule sleeve 32 and then into the switch cabinet 1 through the cable insertion hole 7. After insertion, the threaded rod 35 is rotated, which drives the rack 36 to move. Since the rack 36 is engaged with the arc-shaped rack 37 on the outer side of the movable disk 33, the movement of the rack 36 drives the movable disk 33 to rotate through the arc-shaped rack 37. When the movable disk 33 rotates, it drives the plug-in post 38 to move through the curved groove 34 on the outer side, thereby causing the extrusion block 39 to slide inside the slide groove 311. At this time, multiple extrusion blocks 39 move radially at the same time, thereby extruding the silicone capsule sleeve 32, so that the silicone capsule sleeve 32 can make close contact with the cable, avoiding gaps between the silicone capsule sleeve 32 and the cable, thus preventing small animals or moisture from entering the inside of the switch cabinet 1. Furthermore, through the synchronous radial movement of multiple extrusion blocks 39, the silicone capsule sleeve 32 can seal cables of various diameters. Finally, when multiple switch cabinets 1 need to be spliced ​​together, the switch cabinets 1 on both sides are brought closer together, which in turn causes the hollow plates 41 fixed on the switch cabinets 1 on both sides to move closer together. At this time, the wedge-shaped plug 42 will be inserted into the window 44 opened on the corresponding hollow plate 41. After the wedge-shaped plug 42 is inserted into the window 44, it will contact the wedge-shaped locking block 47. Due to the wedge surface design of the contact surface between the wedge-shaped plug 42 and the wedge-shaped locking block 47, it will push the wedge-shaped locking block 47 to move, thereby causing the support plate 46 to rotate. When the wedge-shaped plug 42 is locked in place, the torsion spring 48 will pull the support plate 46 to rotate in the opposite direction, thereby causing the wedge-shaped locking block 47 to rotate. By moving the wedge-shaped locking block 47 into the slot 43 on the wedge-shaped insert block 42, the wedge-shaped insert block 42 can be fixed inside the hollow plate 41, completing the splicing of the two switch cabinets 1. The two switch cabinets 1 can be connected through the communication port 411 on the side of the switch cabinet 1, and the sealing ring 412 prevents dust and moisture from entering the switch cabinet 1. When it is necessary to contact the splicing of the two switch cabinets 1, rotate the movable rod 45. The movable rod 45 will drive the wedge-shaped locking block 47 to move through the support plate 46, thereby releasing the limiting effect on the wedge-shaped insert block 42, and the two switch cabinets 1 can be separated.

[0038] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
