Description

Technical Field

[0001] This utility model relates to the field of inverter technology, and in particular to a modular inverter. Background Technology

[0002] An inverter is a power conversion device that converts direct current (DC) to alternating current (AC). In wind power systems, it can convert the unstable DC power generated by wind turbines into AC power that meets the grid requirements, enabling effective grid connection of wind power and ensuring stable power transmission and supply.

[0003] An inverter mainly consists of an inverter bridge and a control circuit. Its working principle is that the control circuit drives the semiconductor devices in the inverter bridge to convert direct current into alternating current with adjustable frequency and amplitude. By adjusting the switching on and off of the semiconductor devices, the conversion of electrical energy from the DC side to the AC side is realized.

[0004] In existing technologies, inverters have external ventilation openings, which can easily allow external stones to enter and block the ventilation channels, leading to poor heat dissipation. This causes the internal temperature of the inverter to rise, affecting its performance and stability, reducing conversion efficiency, and even causing overheating failures, shortening the inverter's lifespan, and increasing maintenance costs. Therefore, a modular inverter is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a modular inverter, which aims to improve the problem in the prior art where stone particles entering the inverter vents can clog the channels, cause poor heat dissipation, and thus raise the internal temperature, affecting performance stability and conversion efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A modular inverter includes a mounting frame and a housing. The housing is mounted on the inner wall of the mounting frame. Two positioning components for positioning a disassembly structure are fixedly connected to the outside of the housing. A sliding block and a moving block are slidably connected inside the positioning components. Two slots are formed on the outside of the positioning components. The outer side of the sliding block is slidably connected to the inner wall of one slot, and the outer side of the moving block is slidably connected to the inner wall of the other slot. Two fixed shafts are rotatably connected to the inner wall of the positioning components. A sliding shaft is slidably connected to the inner wall of each fixed shaft. The other end of the sliding shaft is rotatably connected to the outside of the moving block, and the outer side of the other sliding shaft is rotatably connected to the outside of the sliding block.

[0008] As a further description of the above technical solution:

[0009] The positioning component includes two fixing boxes, which are fixedly connected to the outside of the device body, and the positioning box is slidably connected to the outside of the fixing boxes.

[0010] As a further description of the above technical solution:

[0011] Filter plates are fixedly connected to the outside of the two positioning boxes, and the outside of the fixed shaft is rotatably connected to the inner wall of the positioning box, and the outside of the other fixed shaft is rotatably connected to the inner wall of the fixed box.

[0012] As a further description of the above technical solution:

[0013] A spring is fixedly connected to the inner wall of the fixed shaft, and the other end of the spring is fixedly connected to the outside of the sliding shaft.

[0014] As a further description of the above technical solution:

[0015] A motor is installed on the inner wall of the fixed frame, and a rotating rod is fixedly connected to the drive end of the motor.

[0016] As a further description of the above technical solution:

[0017] The rotating rod is externally connected to two connecting rods, and the inner wall of the fixed frame is provided with a movable groove.

[0018] As a further description of the above technical solution:

[0019] The connecting rod is rotatably connected to a movable shaft, the movable shaft is fixedly connected to a clamping plate, and the clamping plate is fixedly connected to a plurality of friction blocks.

[0020] As a further description of the above technical solution:

[0021] The inner wall of the fixed frame is provided with a sliding groove, and the two movable shafts are externally slidably connected to the inner wall of the sliding groove.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the contact surface between the sliding block and the moving block is parallel to the previous contact surface, so that the positioning box can drive the filter plate to detach from the outside of the device body, realizing the replacement of the filter screen. Adding a filter screen that is easy to disassemble and replace to the inverter heat dissipation port can block external impurities such as stone particles from entering and prevent the ventilation channel from being blocked.

[0024] 2. In this utility model, when the two sides are close together, the other end of the connecting rod drives the outer side of the movable shaft to slide on the inner wall of the slide groove, and the traction clamps move closer to each other, so that multiple friction blocks contact the outside of the inverter and install the inverter. This adds a structure that facilitates installation to the inverter, making it easier to arrange and fix in different environments. The convenient installation can save manpower and time costs.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 2 , Figure 4 and Figure 5This utility model provides an embodiment of a modular inverter, including a mounting frame 1 and a main body 2. The main body 2, which is the core of the inverter, is mounted on the inner wall of the mounting frame 1. Two positioning components for positioning the disassembly structure are fixedly connected to the outside of the main body 2. A sliding block 13 and a moving block 14 are slidably connected inside the positioning components. The relative positions of the sliding block 13 and the moving block 14 can form a locking structure. Two slots 15 are formed on the outside of the positioning components. The sliding block 13 is slidably connected to the inner wall of one slot 15, limiting the movement of the sliding block 13. The moving block 14 is slidably connected to the inner wall of the other slot 15, limiting the movement of the moving block 14.

[0034] The positioning assembly has two fixed shafts 16 rotatably connected to its inner wall, and a sliding shaft 17 slidably connected to the inner wall of each fixed shaft 16. Changes in the position of the sliding shaft 17 can cause partial rotation of the fixed shafts 16. The other end of the sliding shaft 17 is rotatably connected to the outside of a moving block 14, and changes in the position of the moving block 14 cause changes in the position of the sliding shaft 17. The other sliding shaft 17 is rotatably connected to the outside of a sliding block 13, and changes in the position of the sliding block 13 cause changes in the position of the other sliding shaft 17. The positioning assembly includes two fixed boxes 11, both of which are fixedly connected to the outside of the device body 2. A positioning box 12 is slidably connected to the outside of each fixed box 11, allowing the device body 2 to be locked and disassembled from the object being removed.

[0035] Two positioning boxes 12 are externally fixedly connected to filter plates 19, which are then removed. One fixed shaft 16 is externally rotatably connected to the inner wall of the positioning box 12, and the other fixed shaft 16 is externally rotatably connected to the inner wall of the fixed box 11. The positioning boxes 12 and fixed boxes 11 fix the rotational position of the fixed shaft 16. A spring 18 is fixedly connected to the inner wall of the fixed shaft 16, fixing one end of the spring 18. The other end of the spring 18 is fixedly connected to the outside of the sliding shaft 17, and changes in the position of the sliding shaft 17 cause the spring 18 to deform.

[0036] Reference Figure 1 and Figure 3A motor 3 is installed on the inner wall of the fixed frame 1. A rotating rod 5 is fixedly connected to the drive end of the motor 3. When the motor 3 is started, the rotation of the drive end of the motor 3 drives the rotating rod 5 to rotate. Two connecting rods 6 are rotatably connected to the outside of the rotating rod 5. The rotation of the rotating rod 5 drives the two connecting rods 6 to change position. A movable groove 4 is provided on the inner wall of the fixed frame 1 to provide a moving position for the drive structure. A movable shaft 7 is rotatably connected to the outside of the connecting rod 6. The position change of the connecting rod 6 drives the position change of the movable shaft 7. A clamping plate 9 is fixedly connected to the outside of the movable shaft 7. The position change of the movable shaft 7 drives the position change of the clamping plate 9. Multiple friction blocks 10 are fixedly connected to the outside of the clamping plate 9 to increase the contact area. A sliding groove 8 is provided on the inner wall of the fixed frame 1. The two movable shafts 7 are slidably connected to the inner wall of the sliding groove 8 to provide a moving position for the movable shafts 7.

[0037] Working principle: By moving one end of the sliding block 13 and the moving block 14, their outer surfaces move closer to the contact surfaces of the fixed box 11 and the positioning box 12. This makes the contact surfaces of the sliding block 13 and the moving block 14 parallel to the previous contact surface, allowing the positioning box 12 to move the filter plate 19 away from the outside of the device body 2. This enables the replacement of the filter screen. Adding a filter screen that is easy to remove and replace to the inverter's heat dissipation port can prevent external impurities such as stone particles from entering and prevent the ventilation channel from being blocked. This helps to maintain good heat dissipation performance, maintain a suitable internal temperature of the inverter, ensure its stable performance and normal conversion efficiency, and facilitate the maintenance of filtration performance.

[0038] The motor 3 is started, and the rotation of the drive end of the motor 3 drives the rotating rod 5 to rotate. The rotation of the rotating rod 5 causes one end of the two connecting rods 6 to move closer to or away from the center of the rotating rod 5. When they are close, the other end of the connecting rod 6 drives the outside of the movable shaft 7 to slide on the inner wall of the slide groove 8, and the traction clamps 9 move closer to each other, so that multiple friction blocks 10 contact the outside of the inverter for installation. This adds a structure that facilitates the installation of the inverter, making it easier to arrange and fix in different environments. The convenient installation can save manpower and time costs, reduce difficulties and risks in the installation process, and help improve the overall efficiency and reliability of the equipment.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
