[0023] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described below.

[0024] To address the problems existing in the background technology, this application proposes the following technical solution: a micro inverter with a fixed structure mounted on a cable tray.

[0025] The specific technical solution includes a micro inverter body 1 and a fixed component 3;

[0026] like Figure 1-4As shown, a cable tray body 2 is installed below the micro-inverter body 1. The cable tray body 2 can be used to install and fix photovoltaic panels. A fixing assembly 3 is installed on the micro-inverter body 1 and the cable tray body 2. The fixing assembly 3 is used to fix the micro-inverter to the cable tray body 2. The fixing assembly 3 includes a sleeve 301, a sliding sleeve 302, a clamp 303, and a spring 304. The sleeve 301 can limit and support the sliding sleeve 302, the sliding sleeve 302 can support the clamp 303, the clamp 303 can clamp the outside of the cable tray body 2, and the spring 304 can pull the sliding sleeves on both sides. 302 enables the sliding sleeve 302 to return to its original position. The sleeve 301 is fixedly connected to the micro inverter body 1. The sliding sleeve 302 slides through the sleeve 301. The gripper 303 is fixedly connected to the sliding sleeve 302. The gripper 303 is sleeved on the outside of the bridge frame body 2. An inclined surface 4 is provided below the gripper 303. The inclined surface 4 facilitates the connection between the gripper 303 and the bridge frame body 2. The spring 304 is installed inside the sleeve 301 and the sliding sleeve 302. The middle part of the spring 304 is fixedly connected to the middle part inside the sleeve 301. The end of the spring 304 is fixedly connected to the inner wall of the sliding sleeve 302.

[0027] according to Figure 1 and Figure 2As shown, two sleeves 301 are provided, rotatably connected between them. One sleeve 301 is fixedly connected to the micro-inverter body 1. Each sleeve 301 has two sliding sleeves 302 inside, and two grippers 303 on its side wall. Each sleeve 301 has a spring 304 inside, with its middle portion fixedly connected to the sleeve 301 and its two ends fixedly connected to the sliding sleeves 302 on both sides. By lifting the micro-inverter body 1, the fixing assembly 3 moves, aligning the inclined plane 4 with the cable tray body 2. By pressing the micro-inverter body 1, the micro-inverter body 1 moves the sliding sleeves 302 and springs 304 via the sleeves 301. The sliding sleeves 302 move the grippers 303 and springs 304, and the grippers 303 cause the inclined plane 4 to press against the cable tray body 2. Since the cable tray body 2 is fixed to the ground, the inclined plane 4 receives a reaction force from the cable tray body 2. 4. The gripper 303 unfolds away from the sleeve 301. The gripper 303 pulls the sliding sleeve 302, which slides outward within the sleeve 301. Simultaneously, the sliding sleeve 302 pulls the spring 304, which exerts a reverse pulling force on the sliding sleeve 302. When both grippers 303 are fully extended and fitted onto the outside of the cable tray body 2, the grippers 303 lose the compression from the side wall of the cable tray body 2. Due to the pulling force of the spring 304, the spring 304 can... Pulling the sliding sleeve 302 into the sleeve 301 allows it to slide quickly. The sliding sleeve 302 can pull the gripper 303 to quickly clamp the cable tray body 2. The gripper 303 can be fixedly sleeved on the outside of the cable tray body 2. The fixation between the gripper 303 and the cable tray body 2 can be achieved by the sliding sleeve 302 driving the sleeve 301 to be fixed to the cable tray body 2. The sleeve 301 can drive the micro inverter body 1 to be fixed to the cable tray body 2, thus quickly fixing the micro inverter body 1 onto the cable tray body 2.

[0028] like Figure 1 and Figure 3 As shown, the gripper 303 is equipped with a locking component 5, which is used to lock the gripper 303. The gripper 303 has a through hole 6, which allows for easy installation of the fixing ring 501, the locking plate 502, and the spring piece 503. The locking component 5 includes the fixing ring 501, the locking plate 502, and the spring piece 503. The fixing ring 501 can fix the locking plate 502, and the locking plate 502 can be connected to the fixing ring 501. The spring piece 503 can drive the locking plate 502 to reset. The fixing ring 501 is fixedly connected to the gripper 303. The locking plate 502 is rotatably installed in the through hole 6 and passes through the fixing ring 501. The two ends of the spring piece 503 are fixedly connected to the bottom surface of the locking plate 502 and the inner bottom surface of the through hole 6, respectively.

[0029] according to Figure 3As shown, since two grippers 303 are provided at both ends of a sleeve 301, the fixing ring 501 is fixedly connected to the gripper 303 at one end of the sleeve 301. A through hole 6 is provided in the gripper 303 at the other end of the sleeve 301. Therefore, the locking plate 502 and the spring piece 503 are installed in the through hole 6 inside the gripper 303 at the other end of the sleeve 301. When the grippers 303 on both sides are pulled and quickly clamped to the outside of the cable tray body 2 by the sliding sleeve 302, the impact force generated by the rapid clamping of the grippers 303 can drive the fixing ring 501 and the through hole 6 to move closer to each other. The through hole 6 can drive the locking plate 502 and the spring piece 503 to move closer to the fixing ring 501. After the grippers 303 are closed, the fixing ring 501 passes through the through hole 6 and squeezes the left side wall of the locking plate 502. Since the left side wall of the locking plate 502 is not inclined, The locking plate 502 is squeezed and rotates clockwise around the central axis of the part connected to the through hole 6. The locking plate 502 squeezes the spring 503, and the spring 503 pushes the right side of the locking plate 502 upward. When the fixing ring 501 is fully inserted into the through hole 6 and located below the left end of the locking plate 502, the locking plate 502 loses the squeezing of the fixing ring 501. The spring 503 can push the locking plate 502 to rotate counterclockwise, and the left end of the locking plate 502 can be inserted into the fixing ring 501. At this time, the locking plate 502 can be fixed with the fixing ring 501. The locking plate 502 can drive the right gripper 303 to be fixed with the fixing ring 501 through the through hole 6. The fixing ring 501 can drive the left gripper 303 to be fixed with the right gripper 303. At this time, it can prevent the gripper 303 from being accidentally unfolded and can better fix the micro inverter body 1.

[0030] like Figure 1 and Figure 4 As shown, the side wall of the micro inverter body 1 is provided with a socket 7, which can be easily connected to the signal line 8.

[0031] like Figure 1 and Figure 4 As shown, a signal line 8 is inserted into the socket 7, and the signal line 8 can transmit signals to the micro inverter body 1.

[0032] like Figure 1 and Figure 4 As shown, a signal light 9 is fixedly installed on the side wall of the micro inverter body 1, and the signal light 9 can display the operating status of the micro inverter body 1.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art.
