[0034] Reference Figure 1-4A photovoltaic grid-connected device that is easy to install includes a grid-connected cabinet body 1 and a mounting base 2. A mounting seat 3 is fixedly connected to the bottom of the grid-connected cabinet body 1. Slots 4 are provided on both sides of the mounting seat 3. A drive motor 5 is fixedly connected to the outer surface of the mounting base 2. A drive gear 6 is fixedly connected to the output end of the drive motor 5. A driven gear 7 meshes with one side of the drive gear 6. A bidirectional threaded rod 8 is inserted into the inner wall of the driven gear 7. A lead screw slide 9 is threadedly connected to the outer surface of the bidirectional threaded rod 8. A limit rod 10 is fixedly connected to the outer surface of the lead screw slide 9. A connecting block 11 is sleeved on the outer wall of the limit rod 10. A locking block 12 is fixedly connected to one side of the connecting block 11. When using this device, first connect the mounting seat 3 below the grid-connected cabinet body 1 to the mounting slots 13 on the mounting base 2. The connection is made, and then the drive motor 5 drives the drive gear 6 to rotate. Through the transmission cooperation of the drive gear 6, driven gear 7, double-threaded rod 8, lead screw slide 9, limit rod 10 and connecting block 11, the two left and right locking blocks 12 are driven to move closer to each other until the two locking blocks 12 are respectively locked into the locking slots 4 on both sides of the mounting base 3, thus completing the fixed installation of the grid-connected cabinet body 1. This avoids the trouble of using bolts and other fixing parts for installation, improves the installation efficiency, and achieves the effect of easy installation of the device. The upper part of the fixing base 2 is provided with a mounting groove 13, and the inner bottom wall of the mounting groove 13 is fixedly connected with a positioning post 14. The lower surface of the mounting base 3 is provided with a positioning hole. The design of the positioning post 14 and the positioning hole can ensure that the mounting base 3 under the grid-connected cabinet body 1 is fixed. To ensure the accuracy of the initial connection with the fixed base 2, and to guarantee that the subsequent locking block 12 can smoothly enter the locking slot 4 for engagement, the inner wall of the mounting slot 13 has two rectangular through holes 15. These rectangular through holes 15 ensure that the locking block 12 can pass through them and smoothly enter the locking slot 4. Two bearing seats 16 are fixedly connected to the inner wall of the fixed base 2. The bidirectional threaded rod 8 is rotatably connected to both bearing seats 16. The two bearing seats 16 provide support and position fixation for the bidirectional threaded rod 8. Two limit plates 17 are sleeved on the outer wall of the bidirectional threaded rod 8. These limit plates 17 restrict the movement range of the screw slide 9, thereby controlling the locking block. To limit the movement distance of the 12-position block 12, a sliding rod 18 is fixedly connected to the inner wall of the fixed base 2, and a sliding sleeve 19 is slidably connected to the outer surface of the sliding rod 18. The sliding sleeve 19 is fixedly connected to the limiting rod 10. By setting the sliding rod 18 and the sliding sleeve 19, the stability of the locking block 12 during position adjustment is improved, ensuring that the locking block 12 can enter the slot 4 horizontally.

By setting the handle 22, the convenience of opening and closing the cabinet door 21 is improved.The outer surface of the cabinet door 21 has a mounting groove, and a glass panel 23 is fixedly connected to the inner wall of the mounting groove. By installing the glass panel 23 on the cabinet door 21, it is convenient for staff to directly observe the operating status of the internal instruments from the outside of the grid-connected cabinet body 1. A support frame 24 is fixedly connected to the upper surface of the grid-connected cabinet body 1, and a rain shield 25 is fixedly connected to the top of the support frame 24. Multiple guide channels 26 are formed on the upper surface of the rain shield 25. This design, with the support frame 24, rain shield 25, and guide channels 26, effectively blocks rainwater, preventing rainwater from impacting the grid-connected cabinet body 1 and causing corrosion. Furthermore, the guide channels 26 quickly divert rainwater falling on the surface of the rain shield 25, preventing rainwater from accumulating above the rain shield 25 and causing excessive pressure on it. This design improves the practicality and service life of the device.

[0035] In this invention, when using the device, firstly, the mounting base 3 below the main body 1 of the grid-connected cabinet is aligned with the mounting groove 13 on the fixed base 2. Then, the drive motor 5 drives the drive gear 6 to rotate. Through the transmission and cooperation of the drive gear 6, driven gear 7, bidirectional threaded rod 8, lead screw slide 9, limit rod 10, and connecting block 11, the two left and right locking blocks 12 are driven to move closer to each other until the two locking blocks 12 are respectively engaged in the locking grooves 4 on both sides of the mounting base 3, thus completing the fixed installation of the main body 1 of the grid-connected cabinet, avoiding the need for fixing with bolts or other fasteners. The simplified installation of parts improves installation efficiency and makes the device easy to install. By setting up the support frame 24, rain shield 25 and guide channel 26, this design can block rainwater and prevent rainwater from impacting the main body of the grid-connected cabinet 1 and causing rust on the surface of the main body of the grid-connected cabinet 1. The guide channel 26 can quickly guide the rainwater falling on the surface of the rain shield 25 down, preventing rainwater from accumulating on the rain shield 25 and causing the rain shield 25 to bear excessive pressure. This design improves the practicality and service life of the device.
