Description

Technical Field

[0001] The utility model relates to the technical field of inverters, and specifically relates to an inverter. Background Art

[0002] An inverter is an electronic device that converts direct current into alternating current. Inverters play a crucial role in wind turbine generators. The electricity generated by wind turbine generators is direct current, which needs to be converted into alternating current before being delivered to the power grid. Inverters can not only achieve the conversion from direct current to alternating current, but also control parameters such as the output current and voltage of the generator to optimize the overall power generation efficiency.

[0003] The patent with the publication number CN217789572U discloses a grid-connected inverter for a wind turbine. It includes a grid-connected inverter body. A box cover is arranged on one side of the grid-connected inverter body. A slide rail is arranged on the side of the grid-connected inverter body away from the box cover. A wiring cover plate is arranged on the slide rail. Locking screws are arranged on the symmetrical sides of the wiring cover plate. Through the arranged chute, rolling bearing, guide rail, fixed angle plate and fixing screws, when the grid-connected inverter needs to be replaced and repaired, only two fixing bolts need to be removed, and the grid-connected inverter slides on the guide rail, which is convenient to take out the grid-connected inverter from the transformer box and improve the replacement efficiency. However, this device first fixes the guide rail on the bottom side of the transformer box body, and then uses the cooperation of the chute and the rolling bearing. After the grid-connected inverter body is pushed in, the bolt holes on the fixed angle plate are accurately aligned with the bolt holes on the grid-connected inverter body and then fixed with fixing bolts. Although this fixing and installation method only uses one bolt for fixation, the installation of the guide rail also requires the use of connecting components such as bolts for fixation, and the distance between the guide rails must be precisely installed in cooperation with the chute fixed at the bottom of the grid-connected inverter body. At the same time, the final fixation of the grid-connected inverter body still requires the use of fixing bolts and only fixes one side, resulting in not only a too complicated installation and fixation process, but also the installation and disassembly of the grid-connected inverter body being unstable and inconvenient. Therefore, an inverter is proposed to solve the problem that the existing inverter is difficult to install and disassemble quickly and stably. Summary of the Utility Model

[0014] (III) Beneficial effects

[0015] 1. For this inverter, by pressing the U-shaped moving plate frame into the second groove through the moving grooves at both ends, and cooperating with the chamfer to make the clamping block disengage from the card slot, the installation seat can be disassembled and removed.

[0016] 2. The inverter is fixed to the base through a suction cup. If the power distribution box is made of metal, the pull rod can be used to drive the clamping plate to rotate by 90 degrees, so that the clamping plate enters the movable groove, and then the strong magnetic column in the movable groove moves downward to adsorb the power distribution box, further fixing the base. Otherwise, the base can be detached, which further facilitates the installation and disassembly of this inverter. Description of the Drawings

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Embodiment: Please refer to Figures 1-4 , an inverter, including a base 1, an inverter body 2 is arranged on the top of the base 1, an installation groove 3 is opened on the top of the base 1, an installation seat 4 is arranged in the inner cavity of the installation groove 3, the installation seat 4 is fixedly connected with the inverter body 2, installation mechanisms 5 are arranged inside both ends of the base 1, two groups of grooves 6 are opened at both ends of the inner cavity wall of the installation groove 3, a spring 7 and a clamping block 8 are arranged in the inner cavity of the groove 6, a chamfer 9 is opened at the right-side opposite boundary of the clamping block 8, card slots 10 are opened at both ends of the installation seat 4, moving grooves 11 are opened at both ends of the installation seat 4, a U-shaped moving plate frame 12 is arranged in the inner cavity of the moving groove 11, and a second groove 13 is opened on one side of the installation seat 4.

[0025] Furthermore, the mounting seat 4 is fixedly connected to the inverter body 2 , and the bottom surface of the mounting seat 4 and the bottom of the inner cavity of the mounting groove 3 are both relatively smooth.

[0026] Furthermore, the two ends of the spring 7 are fixedly connected to the inner wall of the groove 6 and the block 8 respectively, and the two sides of the U-shaped movable plate frame 12 are penetrated by a groove 10. When the mounting seat 4 is located in the mounting groove 3, the groove 6 and the groove 10 are interconnected.

[0027] Furthermore, one side of the U-shaped movable plate frame 12 is located in the second groove 13 and the right side surface is flush with the mounting seat 4. When the right side surface of the U-shaped movable plate frame 12 is flush with the mounting seat 4, the card slots 10 at both ends are interconnected with the card slots 10 on the mounting seat 4.

[0028] Furthermore, the mounting mechanism 5 includes four movable grooves 501 opened at the bottom of the base 1. The inner cavity of the movable groove 501 is provided with a strong magnetic column 502. The top of the strong magnetic column 502 is rotatably connected to a pull rod 503 by a bearing.

[0029] Furthermore, a second slot 504 is provided through the top of the inner cavity wall of the movable slot 501, and a clamping plate 505 is fixedly connected to the outer ring of the pull rod 503. The clamping plate 505 has the same shape as the second slot 504, and four suction cups 506 are fixedly connected to the bottom of the base 1. When the inverter body 2 is removed to install the base 1, the suction cups 506 can be directly used to fix the base 1. If the transformer box is made of metal, the pull rod 503 can be used to drive the clamping plate 505 to rotate ninety degrees so that the clamping plate 505 enters the movable slot 501, thereby causing the strong magnetic column 502 in the movable slot 501 to move downward to adsorb the transformer box, thereby further fixing the base 1.

[0030] Furthermore, a slot 14 is penetrated through one side of the U-shaped movable plate frame 12, and a handle 15 is provided in the inner cavity of the slot 14. The handle 15 is fixed at the bottom of the inner cavity of the second groove 13. When the U-shaped movable plate frame 12 is pushed into the second groove 13, the relative positions of the handle 15 and the slot 14 will change, and the handle 15 can be used to pull the mounting seat 4 together with the inverter body 2 fixed on the top out of the mounting groove 3, so as to facilitate the removal, cleaning and maintenance of the inverter body 2.

[0031] Working principle: When using this inverter, the base 1 is installed together with the inverter body 2 in the transformer box by using the installation mechanism 5. When disassembling and repairing the inverter body 2, the U-shaped movable plate frame 12 is pressed into the second groove 13 in cooperation with the movable grooves 11 at both ends, and the block 8 is disengaged from the slot 10 in cooperation with the chamfer 9 so that the mounting seat 4 can be moved out. Conversely, the mounting seat 4 is pushed into the mounting slot 3. During the process, in cooperation with the chamfer 9, the block 8 compresses the spring 7 by itself. After the mounting seat 4 is completely pushed into the mounting slot 3, the block 8 enters the slot 10 in cooperation with the elastic force of the spring 7 to complete the fixation of the mounting seat 4, thereby solving the problem that the existing inverter is difficult to install and disassemble quickly and stably.
