One side inside the outer end of the electrical cabinet 1 is connected to the outside of the heat dissipation outer frame 2. The inside of the heat dissipation outer frame 2 is connected to the outside of the heat dissipation fan 4 through the connecting frame 3. The output end of the heat dissipation fan 4 is connected to the middle of the inner end of the fan blade 5. The left side of the front end of the heat dissipation outer frame 2 is movably connected to the right side of the front end of the closing frame 7 through the hinge 6. A locking mechanism and an opening and fixing mechanism are respectively arranged between the heat dissipation outer frame 2 and the closing frame 7; when the closing frame 7 is closed outside the heat dissipation outer frame 2 and fixed by the locking mechanism, under the connection of the connecting frame 3 and through the operation of the heat dissipation fan 4, the fan blade 5 can rotate to form an air flow, which acts on the inside of the electrical cabinet 1 for heat dissipation. When the locking mechanism is opened, the closing frame 7 can be opened under the constraint of the hinge 6 and fixed by the opening and fixing mechanism after reaching the position, and then the internal heat dissipation fan 4 and the fan blade 5 can be overhauled and maintained.

[0025] The locking mechanism includes a lock ring 8, a moving pin frame 9 and a fixed pin piece 10. The middle of the bottom end of the closing frame 7 is rotatably connected to the inside of the lock ring 8. The output end of the lock ring 8 is connected to one side of the inner end of the moving pin frame 9. The front middle part of the bottom end inside the heat dissipation outer frame 2 is connected to the bottom end of the fixed pin piece 10; when the closing frame 7 is closed, by turning the lock ring 8, the moving pin frame 9 can be rotated and inserted into the fixed pin piece 10 to fix the closing frame 7 in a closed state and improve stability.

[0026] The opening fixing mechanism includes a sliding pin frame 11, a pin rod 12, a pressing and pulling piece 13, and a pin groove frame 14. The left front side of the top end of the heat dissipation outer frame 2 is connected to the bottom end of the pin groove frame 14, and the right front side of the top end of the closing frame 7 is connected to the bottom end of the sliding pin frame 11. The inner side of the sliding pin frame 11 is slidably connected to the outer side of the pin rod 12, and the outer end of the pin rod 12 is connected to the middle of the inner end of the pressing and pulling piece 13. After the closing frame 7 is opened in place, the sliding pin frame 11 and the pin groove frame 14 correspond to each other. By pressing the pressing and pulling piece 13, the pin rod 12 can slide inside the sliding pin frame 11, so as to be inserted into the pin groove frame 14, fixing the opening of the closing frame 7 and improving the stability.

[0027] It also includes an internal thread frame 15, a tightening screw rod 16, a tightening wrench 17, and a dust filter mesh 20. The dust filter mesh 20 is detachably arranged at the rear side inside the closing frame 7. The middle parts of the left and right ends inside the closing frame 7 are respectively connected to the outer sides of a group of internal thread frames 15. The inner wall of the internal thread frame 15 is screwed with the outer wall of the tightening screw rod 16, and the outer side of the tightening screw rod 16 is connected to the middle of the inner side of the tightening wrench 17. When the dust filter mesh 20 is installed at the rear side inside the closing frame 7, by turning the two tightening wrenches 17, the corresponding tightening screw rods 16 can be rotated. The tightening screw rods 16 can act inwardly on the corresponding positions on the front side of the dust filter mesh 20 through screwing cooperation with the internal thread frames 15, fixing the dust filter mesh 20 at this position and providing internal dust filtering protection when the closing frame 7 is closed, improving the reliability.

[0028] It also includes a buffer strip 18. The front end annular side of the heat dissipation outer frame 2 is connected to the rear side of the buffer strip 18.

[0030] In summary, when a heat dissipation power unit device for a power project is in use, when the dust filter net 20 is installed at the rear side inside the closing frame 7, by turning two sets of tightening knobs 17, the corresponding tightening screw rods 16 can be rotated. The tightening screw rods 16 are screwed and matched with the internal thread frames 15, and can act inwardly to tighten the corresponding positions on the front side of the dust filter net 20, so that the dust filter net 20 is fixed at this position. When the closing frame 7 is closed outside the heat dissipation outer frame 2, through the contact buffer of the buffer strip 18, by turning the lock ring 8, the moving pin frame 9 can be rotated and inserted into the fixed pin piece 10, so that the closing frame 7 is closed and fixed. Under the connection of the connecting frame 3, when the heat dissipation fan 4 operates, the fan blades 5 can rotate to form an air flow, which acts on the interior of the electrical cabinet body 1 for heat dissipation, and the dust filter net 20 provides internal dust filtering protection. When the moving pin frame 9 is opened outside the fixed pin piece 10, the closing frame 7 can be opened under the constraint of the hinge 6. After in place, the sliding pin frame 11 and the pin slot frame 14 correspond. By pressing the pull piece 13, the pin rod 12 can slide inside the sliding pin frame 11 and then be inserted into the pin slot frame 14, so that the closing frame 7 is opened and fixed. After that, the internal heat dissipation fan 4 and the fan blades 5 can be repaired and maintained.
