[0028] 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.

[0029] like Figures 1 to 6 As shown, this utility model provides a photovoltaic system data acquisition terminal, including a device body 1, and a support and installation mechanism 2 is provided on the outside of the device body 1;

[0030] The support and installation mechanism 2 includes an installation frame 21. A stabilizing plate 22 is snapped into the inside of the installation frame 21. A rotating component 23 is fixedly connected to the outside of the stabilizing plate 22. A connecting frame 24 is provided on the outside of the rotating component 23. A support plate 25 is installed inside the connecting frame 24. A gravity block 26 is fixedly connected to the bottom of the support plate 25. A hidden box 27 is fixedly connected to the top of the installation frame 21. A positioning groove 28 is opened inside the stabilizing plate 22. A movable tube 29 is fixedly connected to the top of the hidden box 27. A moving rod 210 is movably connected inside the movable tube 29. A compression spring 211 is fixedly connected to the outside of the moving rod 210. A positioning block 212 is fixedly connected to the bottom of the moving rod 210. A lifting port 213 is opened between the installation frame 21 and the hidden box 27.

[0031] Specifically, the mounting frame 21 is fixedly connected to the outside of the equipment body 1, and the stabilizing plate 22 is movably connected to the outside of the connecting frame 24 through the rotating part 23. Through the cooperation of the rotating part 23 and the connecting frame 24, the equipment body 1 can be installed between the two support plates 25.

[0032] like Figures 1 to 6 As shown, the support plate 25 and the gravity block 26 are symmetrically distributed on the outside of the main body 1 of the equipment. The positioning groove 28 is located directly below the lifting port 213. Since the gravity block 26 has a certain gravity, it can make the main body 1 of the equipment maintain stability between the support plates 25.

[0033] Furthermore, the bottom of the compression spring 211 is fixedly connected to the top of the movable tube 29, and the initial position of the positioning block 212 is located inside the positioning groove 28. Through the characteristics of the compression spring 211 itself, the positioning block 212 is stably engaged inside the positioning groove 28, and the size of the positioning groove 28 matches the positioning block 212.

[0034] like Figures 1 to 6 As shown, a lifting mechanism 3 is provided on the outside of the connecting frame 24. The lifting mechanism 3 includes a sliding groove 31. A threaded pipe 32 is fixedly connected to the outside of the connecting frame 24. A screw 33 is threadedly connected to the inside of the threaded pipe 32.

[0035] It is worth noting that the support plate 25 is slidably connected inside the sliding groove 31, and the screw 33 passes through the inside of the threaded tube 32. The screw 33 moves by rotating inside the threaded tube 32.

[0036] like Figures 1 to 6 As shown, the screw 33 is movably connected inside the sliding groove 31, and one end of the screw 33 is in close contact with the outside of the support plate 25. When the screw 33 moves to the outside of the support plate 25 inside the sliding groove 31, it can position the support plate 25 inside the sliding groove 31.

[0037] Furthermore: a cleaning mechanism 4 is provided between the support plates 25. The cleaning mechanism 4 includes a controller 41. A slide rail 42 is fixedly connected between the support plates 25. An electric slider 43 is slidably connected to the outside of the slide rail 42. A starter 44 is provided on the outside of the electric slider 43. An air suction machine 45 is fixedly connected to the top of the electric slider 43. An air inlet plate 46 is fixedly connected to the top of the air suction machine 45. A heat dissipation hole 47 is opened in the inner bottom wall of the main body of the equipment 1.

[0038] It should be noted that the suction machine 45 and the air inlet plate 46 are located below the main body 1 of the equipment, and the heat dissipation holes 47 are evenly distributed in the inner bottom wall of the main body 1 of the equipment.

[0039] Furthermore, by connecting to devices such as photovoltaic grid-connected inverters, combiner boxes, weather stations, and electricity meters via downlink communication protocols such as RS485, RS232, and RS422, data from these devices is collected, and then transmitted to a database or monitoring platform via uplink connections such as GPRS, Ethernet, WIFI, and 3G.

[0040] Working principle and process: With the main body 1 set up, after the main body 1 is finished using, the moving rod 210 moves upward inside the movable tube 29, causing the moving rod 210 to drive the positioning block 212 through the lifting port 213 into the hidden box 27. At this time, the positioning block 212 will move out of the positioning groove 28 inside the stabilizing plate 22, thus no longer limiting the stabilizing plate 22, thereby removing the stabilizing plate 22 from the mounting frame 21 outside the main body 1, achieving a quick disassembly effect. With the main body 1 set up, the support plate 25 and the gravity block 26 work together to support the main body 1. When unevenness occurs, the two sides of the main body 1 need to be adjusted. This is done by rotating the screw 33. The screw 33 rotates and moves inside the threaded tube 32, causing one end of the screw 33 to move away from the support plate 25. It slides in the sliding groove 31 inside the connecting frame 24 through the support plate 25, thereby adjusting the height of both sides of the main body 1 and ensuring that the main body 1 remains stable. When the dust inside the heat dissipation hole 47 at the bottom of the main body 1 needs to be cleaned, the suction machine 45 is started to generate suction. The air intake plate 46 then sucks up the dust at the bottom of the main body 1. The controller 41 then starts the electric slider 43 on the outside of the slide rail 42, which drives the suction machine 45 and the air intake plate 46 to move at the bottom of the main body 1, thus preventing dust from clogging the heat dissipation hole 47.
