Description

Technical Field

[0001] This utility model belongs to the field of inverter disassembly and assembly technology, and specifically relates to an inverter disassembly and assembly tool. Background Technology

[0002] A photovoltaic inverter is a core device that converts the direct current generated by photovoltaic panels into alternating current. It has maximum power point tracking and islanding protection functions. Its structure typically includes a DC-DC converter, an inverter bridge circuit, and power electronic switching devices to optimize system efficiency and output stable alternating current. Currently, photovoltaic inverters require disassembly and assembly work for maintenance, fault diagnosis, or structural optimization.

[0003] Traditional disassembly and assembly methods typically involve placing the inverter directly on a workbench and then operating it using tools such as screwdrivers or electric drills. However, due to the large size and weight of photovoltaic inverters, it is difficult to achieve flexible multi-angle adjustment when placed horizontally, resulting in limited work space. At the same time, different operators have individual needs for tilt angles due to differences in height and operating habits, which cannot be adapted to the existing flat fixing method, easily leading to increased physical exertion for operators and reduced disassembly and assembly efficiency. Utility Model Content

[0004] In view of this, the present invention provides an inverter disassembly and assembly tool, which supports multi-angle adjustment through the disassembly and assembly unit to adapt to the personalized needs of different operators, reduce the physical labor required for operation and improve the efficiency of photovoltaic inverter disassembly and assembly. It not only stabilizes the disassembly and assembly platform to prevent idle shaking, but also transforms the bottom box into tool storage space. The overall modular linkage design significantly improves the adaptability, ease of operation and space utilization of photovoltaic inverter disassembly and assembly.

[0005] To address the aforementioned technical problems, this utility model provides an inverter assembly / disassembly tool, comprising a base box and an assembly / disassembly unit disposed on its upper end. The assembly / disassembly unit includes an assembly / disassembly platform rotatably connected to an opening on one side of the base box. The assembly / disassembly platform has a plurality of evenly distributed limiting grooves on the outer arc surface near the opening on one side of the base box. A sliding groove is provided on the side of the inner cavity of the base box near the limiting grooves. A rectangular box is slidably connected within the sliding groove, and a limiting plate is slidably connected within the rectangular box. The limiting grooves are all movably inserted into the limiting plate. Springs are provided at both ends between the limiting plate and the rectangular box. The assembly / disassembly platform is equipped with mounting components, supporting multi-angle adjustment to accommodate the personalized needs of different operators, reducing physical exertion and improving the efficiency of photovoltaic inverter assembly / disassembly. It stabilizes the assembly / disassembly platform to prevent wobbling during idle periods and transforms the base box into tool storage space. The overall modular and interconnected design significantly improves the adaptability, ease of operation, and space utilization of photovoltaic inverter assembly / disassembly.

[0006] The disassembly and assembly unit also includes a pull rod located at the lower end of the limiting plate. The pull rod is slidably connected to a sliding hole on the rectangular box. The pull rod passes through a through hole near the sliding hole in the bottom box and extends to the outside. An adjustment component for driving the rectangular box to move is also provided in the through hole, which serves to unlock the box.

[0007] The assembly and disassembly unit also includes a lever located at the lower end of the lever, making it easy for staff to operate.

[0008] The adjustment assembly includes a threaded sleeve rotatably connected to the through hole, and an external threaded tube at the lower end of the limiting plate. The external threaded tube is threadedly connected to the threaded sleeve. The pull rod passes through the middle of the external threaded tube and the threaded sleeve in sequence, thus achieving the function of quick adjustment.

[0009] The adjustment assembly also includes a protruding post at the top of the rectangular box. A limiting hole is provided in the middle of the outer arc surface of the disassembly platform near the opening on the bottom box side. The limiting hole is movably inserted into the protruding post, which serves as a limiting and locking function.

[0010] The mounting components include several dovetail grooves located on the upper part of the mounting platform. Several mounting seats are slidably connected within each mounting platform. Each mounting seat is threaded with a locking bolt. The inner end of the locking bolt is in contact with the bottom of the inner cavity of the dovetail groove it is located in. The mounting seat is provided with several mounting holes, which can accurately fit the inverter size.

[0011] The upper front side of the limiting plate is inclined to facilitate smooth movement between structures.

[0012] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0013] 1. Adjust the tilt angle of the inverter by rotating the disassembly and assembly platform connected to the base box. At this time, the edge of the limit slot will contact the inclined surface of the limit plate and push it to overcome the elastic force of the spring and retract into the rectangular box. When the next limit slot moves to align with the limit plate, the spring rebounds and makes it quickly reset and insert into the limit slot, thereby locking the current angle of the disassembly and assembly platform. It supports multi-angle adjustment to meet the personalized needs of different operators, reduce the physical labor required for operation and improve the efficiency of photovoltaic inverter disassembly and assembly. If unlocking is required, the lever at the end of the pull rod can be pressed down to force the limit plate to disengage from the limit slot, realizing free angle adjustment. Other tools can be stored inside the base box.

[0014] 2. After disassembly and assembly are completed and the disassembly and assembly platform is reset, rotate the threaded sleeve. The threaded sleeve and the external threaded pipe drive the rectangular box to move upward along the slide groove, so that the protrusion inserts into the limiting hole to form a secondary limit. This not only stabilizes the disassembly and assembly platform to prevent it from shaking when idle, but also transforms the bottom box into a tool storage space. The overall modular linkage design significantly improves the adaptability, ease of operation and space utilization of photovoltaic inverter disassembly and assembly.

[0015] 3. The relevant personnel first adjust the relative positions of several mounting bases in their respective dovetail grooves according to the size of the photovoltaic inverter to be disassembled and installed. Then, they tighten the locking bolts in sequence to limit and fix the mounting bases. Finally, the inverter is fixed to several mounting bases through several mounting holes to accurately match the size of the photovoltaic inverter. Attached Figure Description

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0022] This embodiment provides an inverter disassembly and assembly tool, such as... Figure 1-4As shown: The system includes a base box 100 and a disassembly / assembly unit disposed on its upper end. The disassembly / assembly unit includes a disassembly / assembly platform 200 rotatably connected to an opening on one side of the base box 100. The disassembly / assembly platform 200 has a plurality of evenly distributed annular limiting grooves 201 on the middle of its outer arc surface near the opening on the side of the base box 100. A sliding groove 202 is provided on the side of the inner cavity of the base box 100 near the limiting grooves 201. A rectangular box 203 is slidably connected within the sliding groove 202. A limiting plate 204 is slidably connected within the rectangular box 203. All the limiting grooves 201 are movably inserted into the limiting plate 204. Springs 205 are provided at both ends between the positioning plate 204 and the rectangular box 203 it is located in. The disassembly and assembly platform 200 is provided with mounting parts. The disassembly and assembly unit also includes a pull rod 206 provided at the lower end of the limiting plate 204. The pull rod 206 is slidably connected to the sliding hole provided on the rectangular box 203. The pull rod 206 passes through the through hole provided near the sliding hole in the bottom box 100 and extends to the outside. An adjustment component for driving the rectangular box 203 to move is also provided in the through hole. The disassembly and assembly unit also includes a lever plate 207 provided at the lower end of the pull rod 206. The upper front side of the limiting plate 204 is inclined.

[0023] The tilt angle of the inverter can be adjusted by rotating the disassembly and assembly platform 200 connected to the base box 100. At this time, the edge of the limiting groove 201 will contact the inclined surface of the limiting plate 204 and push it to overcome the elastic force of the spring 205 and retract into the rectangular box 203. When the next limiting groove 201 moves to align with the limiting plate 204, the spring 205 rebounds to make it quickly reset and insert into the limiting groove 201, thereby locking the current angle of the disassembly and assembly platform 200. It supports multi-angle adjustment to meet the personalized needs of different operators, reduce the physical labor required for operation and improve the efficiency of photovoltaic inverter disassembly and assembly. If unlocking is required, the lever 207 at the end of the pull rod 206 can be pressed down to force the limiting plate 204 to disengage from the limiting groove 201, realizing free angle adjustment. Other tools can be stored inside the base box 100.

[0024] like Figure 2-4 As shown, the adjustment assembly includes a threaded sleeve 300 rotatably connected in the through hole, an external threaded tube 301 at the lower end of the limiting plate 204, the external threaded tube 301 being threadedly connected to the threaded sleeve 300, and a pull rod 206 passing through the middle of the external threaded tube 301 and the threaded sleeve 300 in sequence. The adjustment assembly also includes a protrusion 302 set at the upper end of the rectangular box 203, and a limiting hole 303 at the middle of the outer arc surface of the disassembly platform 200 near the opening on the side of the bottom box 100, the limiting hole 303 being movably inserted into the protrusion 302.

[0025] After disassembly and assembly are completed and the disassembly and assembly platform 200 is reset, the threaded sleeve 300 is rotated. The threaded sleeve 300 and the external threaded tube 301 drive the rectangular box 203 to move upward along the slide groove 202, so that the protrusion 302 is inserted into the limiting hole 303 to form a secondary limit. This not only stabilizes the disassembly and assembly platform 200 to prevent it from shaking when idle, but also transforms the bottom box 100 into a tool storage space. The overall modular linkage design significantly improves the adaptability, ease of operation and space utilization of photovoltaic inverter disassembly and assembly.

[0026] like Figure 1-2 As shown, the mounting component includes several dovetail grooves 400 disposed on the upper end of the disassembly platform 200. Several mounting seats 401 are slidably connected in each disassembly platform 200. Each mounting seat 401 is threadedly connected with a locking bolt 402. The inner end of the locking bolt 402 is in contact with the bottom of the inner cavity of the dovetail groove 400 in which it is located. Several mounting holes are provided on the mounting seat 401.

[0027] The relevant staff first adjust the relative positions of several mounting bases 401 within their respective dovetail grooves 400 according to the size of the photovoltaic inverter to be disassembled and installed. Then, they tighten the locking bolts 402 in sequence to limit and fix the mounting bases 401. Finally, the inverter is fixed to several mounting bases 401 through several mounting holes to accurately fit the size of the photovoltaic inverter.

[0028] The working principle of the inverter disassembly and assembly tool provided by this utility model is as follows: First, the relevant personnel adjust the relative positions of several mounting bases 401 within the dovetail groove 400 according to the size of the photovoltaic inverter to be disassembled or assembled. Then, they tighten the locking bolts 402 to limit and fix the mounting bases 401, ensuring precise fit to the photovoltaic inverter size. Next, they rotate the disassembly and assembly platform 200 connected to the base box 100 to adjust the inverter's tilt angle. At this time, the edges of the limiting groove 201 will contact the inclined surface of the limiting plate 204 and push it to overcome the elastic force of the spring 205 and retract into the rectangular box 203. When the next limiting groove 201 moves to align with the limiting plate 204, the spring 205 rebounds, causing it to quickly reset and insert into the limiting groove 201, thereby locking the current angle of the disassembly and assembly platform 200. This supports multiple... The angle adjustment is adapted to meet the individual needs of different operators, reducing the physical demands of operation and improving the efficiency of photovoltaic inverter disassembly and assembly. If unlocking is required, the lever 207 at the end of the pull rod 206 can be pressed down to force the limiting plate 204 to disengage from the limiting groove 201, achieving free angle adjustment. The bottom box 100 can also store other tools. After disassembly and assembly are completed and the disassembly and assembly platform 200 is reset, the threaded sleeve 300 is rotated. The threaded sleeve 300 and the external threaded tube 301 drive the rectangular box 203 to move upward along the slide groove 202, so that the protrusion 302 is inserted into the limiting hole 303 to form a secondary limit. This not only stabilizes the disassembly and assembly platform 200 to prevent idle shaking, but also transforms the bottom box 100 into a tool storage space. The overall modular linkage design significantly improves the adaptability, ease of operation, and space utilization of photovoltaic inverter disassembly and assembly.

[0029] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
