Large-area photovoltaic power stations are mostly set up in areas with flat terrain, no plant shading and long sunshine hours, such as Xinjiang. In such areas, the population is small, the wind and sand are large, and there are wild beasts of different sizes. It is necessary to install fences on the ground surface around the photovoltaic inverter cabinets. However, independent fences need to be installed and fixed with independent structures, which is cumbersome to operate and the connection relationship with the photovoltaic inverter cabinets is not close. When there are many photovoltaic inverter cabinets, individual parts of the long-distance fences on the periphery are also prone to damage under the attack of wind and sand and wild beasts. After the damage, all photovoltaic inverter cabinets lose protection. In view of the above problems, it is urgent to innovate and design on the basis of the original photovoltaic inverter cabinets.

Specific embodiments

[0020] 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.

[0021] Please refer to Figures 1-4 , the present utility model provides a technical solution: a assembled photovoltaic inverter cabinet, including a cabinet body 1, a substrate 2, a supporting threaded column 3, a supporting sleeve 4, a bottom plate 5, a locking bolt 6, a locking nut 7, a track window 8, a side support plate 9, an anchor pin 10, a reinforcing rib plate 11, a vertical threaded rod 12, a connecting plate 13, a positioning nut 14, a protective net 15 and an outer frame 16. The substrate 2 is installed at the bottom of the cabinet body 1. The supporting threaded columns 3 are fixed at the bottom corners of the bottom surface of the substrate 2. The supporting sleeves 4 are threadedly installed at the bottoms of the supporting threaded columns 3. The bottom ends of the supporting sleeves 4 are fixed with the bottom plate 5. The above structural design enables the supporting sleeve 4 to drive the bottom plate 5 to conveniently rotate and adjust the working position along the supporting threaded column 3. The supporting threaded column 3, the supporting sleeve 4 and the bottom plate 5 are all symmetrically distributed about the center of the substrate 2. The diameter of the bottom plate 5 is not less than 2 times the diameter of the supporting threaded column 3. The above structural design ensures that the bottom plate 5 can be in large-area contact with the ground to stably support the cabinet body 1 and the substrate 2;

[0022] When using this device, first use a hoisting tool to horizontally hoist the cabinet body 1 and the substrate 2 to the installation position. Then, according to the unevenness of the ground, rotate all the supporting sleeves 4. The supporting sleeves 4 move downward along the supporting threaded columns 3 until the bottom plate 5 is in close contact with the ground;

[0023] The locking bolt 6 is mounted on the side of the substrate 2, and the locking nut 7 is mounted at the end of the locking bolt 6. The locking bolt 6 passes through the track window 8, and the track window 8 is opened in the vertical part of the side support plate 9. The side support plate 9 is attached to the side of the substrate 2. The locking bolt 6 is in close contact with the inner wall of the track window 8. The locking bolt 6 and the track window 8 are both symmetrically distributed about the center of the side support plate 9. The side view shape of the side support plate 9 is an "L" shape, and the side support plate 9 is symmetrically distributed about the center of the substrate 2. The above structural design enables the side support plate 9 to slide relatively with the track window 8 and the locking bolt 6, so that the working position of the side support plate 9 can be adjusted conveniently according to the ground flatness, ensuring that the cabinet 1 and the substrate 2 are horizontally installed;

[0024] Then, the track window 8 on the side support plate 9 is fitted with the locking bolt 6, the locking nut 7 is installed at the end of the locking bolt 6, and the side support plate 9 is assembled on the side of the substrate 2. At this time, the locking nut 7 is in a loose adjustment state. Then, the side support plate 9 is pushed to slide vertically downward along the locking bolt 6 with the track window 8 until the bottom surfaces of all the side support plates 9 are in contact with the ground. The locking nut 7 is rotated to squeeze the side support plate 9 against the side of the substrate 2 for fixation. The anchor pin 10 is used to pass through the bottom of the side support plate 9 and connect to the ground to support the cabinet 1 and the substrate 2 to keep horizontal, completing the assembly and fixation of the bottom support structure of the cabinet 1 and the substrate 2;

[0025] The bottom end of the side support plate 9 is provided with the anchor pin 10, and the reinforcing rib plate 11 is welded and fixed on the side support plate 9. The anchor pins 10 are symmetrically distributed about the center of the side support plate 9, and the reinforcing rib plates 11 are vertically and equally spaced. The above structural design makes the overall structural strength of the side support plate 9 relatively high and can be stably connected to the ground to stably support the cabinet 1 and the substrate 2. The top of the side support plate 9 is fixed with the vertical threaded rod 12. The vertical threaded rod 12 passes through the connecting plate 13, and the positioning nut 14 is installed on the vertical threaded rod 12. The connecting plate 13 is fixed on the protective net 15, and the protective net 15 is installed inside the outer frame 16. The positioning nuts 14 are symmetrically distributed above and below the center of the connecting plate 13. The inner wall of the hole opened in the center of the connecting plate 13 is in close contact with the vertical threaded rod 12. The vertical threaded rod 12 is symmetrically distributed about the center of the side support plate 9. The above structural design enables the protective net 15 and the outer frame 16 to slide vertically adaptively along the vertical threaded rod 12 with the connecting plate 13 after the installation height of the side support plate 9 is adjusted, and the relative position is quickly locked by squeezing the connecting plate 13 with the symmetrically distributed positioning nuts 14. The outer frame 16 is symmetrically distributed about the center of the cabinet 1, and the adjacent sides of the outer frame 16 are in close contact. The above structural design ensures that the protective net 15 and the outer frame 16 can fully shield and protect the four sides of the cabinet 1;

[0026] Subsequently, the installation of the protective net 15 and the outer frame 16 is carried out. First, a positioning nut 14 is installed on the vertical threaded rod 12, and the positioning nut 14 is rotated to the bottommost end. Then, the holes opened on the connecting plate 13 on the outer side of the protective net 15 and the outer frame 16 are vertically aligned with the top end of the vertical threaded rod 12. The protective net 15 and the outer frame 16 are moved downward, and the vertical threaded rod 12 slides into the holes opened on the connecting plate 13 until the bottom end of the outer frame 16 fits against the edge of the top surface of the substrate 2. Then, another positioning nut 14 is installed on the vertical threaded rod 12, and the positioning nut 14 is rotated as Figure 1 and Figure 2 shown to squeeze the upper and lower end faces of the connecting plate 13 to fix the positions of the connecting plate 13, the protective net 15 and the outer frame 16. As Figure 3 shown, the protective net 15 and the outer frame 16 are spliced and installed around the substrate 2, thus completing the rapid assembly of the protective structure and ensuring the normal operation of the cabinet 1.

[0027] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
