[0027] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] like Figures 1-6 As shown, a box-type step-up transformer structure includes: a metal box 1, a blocking shell 5 and a guide shell 8,

[0029] The side ends of the metal box 1 are respectively provided with an exhaust port 3 and a water outlet 4. The exhaust port 3 is located at the top of the water outlet 4. The blocking shell 5 is fixedly connected to the inner wall of the metal box 1. The cross section of the blocking shell 5 is arc-shaped. The blocking shell 5 cooperates with the exhaust port 3. A plurality of exhaust holes 13 are provided on the top of the blocking shell 5. When the metal box 1 is set outdoors in rainy weather, the step-up transformer is installed in the metal box 1. Rainwater will enter the metal box 1 through the exhaust port 3. The blocking shell 5 blocks the incoming rainwater. Since the rainwater will not move vertically upward when entering the metal box 1, Therefore, when heat is dissipated in the metal box 1, the flowing air carries the heat and flows out from the exhaust holes 13 opened at the top of the blocking shell 5. The flowing air flows downward from the top of the blocking shell 5 and finally flows out from the exhaust port 3 and the water outlet 4 respectively. The flowing air provides resistance to the rainwater, further preventing the rainwater from moving vertically upward. The shape of the blocking shell 5 achieves the effect of blocking the rainwater. At the same time, the blocking shell 5 buffers the rainwater, and the rainwater flows downward along the inner wall of the blocking shell 5, thereby achieving the effect of guiding the rainwater by the blocking shell 5.

[0030] The top of the diversion shell 8 is fixedly connected to the blocking shell 5, and the two ends of the diversion shell 8 are respectively fixedly connected to the inner wall of the metal box 1. The diversion shell 8 cooperates with the water outlet 4. When rainwater flows along the blocking shell 5 to the diversion shell 8, the rainwater accumulates at the diversion shell 8, and then the rainwater is discharged from the water outlet 4 along the diversion shell 8. The diversion shell 8 and the water outlet 4 cooperate to achieve the effect of discharging rainwater.

[0031] In some specific embodiments, the cross-section of the guide shell 8 is bent, and the blocking shell 5 is connected to an exhaust fan 9, which is fixedly connected to the bottom end of the inner wall of the metal box 1. The shape of the guide shell 8 achieves the effect of diverting rainwater. When the operating temperature of the step-up transformer in the metal box 1 rises, the exhaust fan 9 starts to run, and the exhaust fan 9 sprays the air in the metal box 1 upward, and the flowing air is discharged at the top of the blocking shell 5.

[0032] In some specific embodiments, the inner wall of the metal box 1 is fixedly connected to a collecting shell 10, the top of the collecting shell 10 is fixedly connected to the inner wall of the metal box 1, and the side end of the collecting shell 10 is fixedly connected to a locking seat 14. The locking seat 14 passes through the collecting shell 10 and is provided with a connecting hole 15. A connecting rod 11 is slidably connected in the connecting hole 15, and the connecting rod 11 cooperates with the guide shell 8. The end of the connecting rod 11 close to the locking seat 14 is fixedly connected to a pull ring 16, and the end of the locking seat 14 away from the locking seat 14 is fixedly connected to a cleaning plate 7, and the cleaning plate 7 is cooperated with the inner wall of the guide shell 8. The outer wall of the locking seat 14 is threadedly connected to a locking nut 12, and the inner diameter of the locking nut 12 is larger than the diameter of the pull ring 16. The inner wall of the locking nut 12 is abutted against the exhaust hole 13. When the flowing air moves upward, the air enters the collecting shell 10, and the collecting shell 10 collects the air carrying heat. The shape of the guide shell 8 plays a role. To guide the airflow, when dust accumulates on the surface of the guide shell 8 and needs to be cleaned, the staff opens the metal box 1 and rotates the locking nut 12, thereby releasing the threaded connection between the locking nut 12 and the locking seat 14, and further releasing the positioning effect of the locking nut 12 on the pull ring 16. The staff controls the pull ring 16 to move the connecting rod 11, and the connecting rod 11 slides along the inner wall of the connecting hole 15. The connecting rod 11 drives the cleaning plate 7 to clean the dust accumulated on the surface of the guide shell 8. When the dust on the surface of the guide shell 8 is cleaned, the cleaning plate 7 is reset, and the locking nut 12 is rotated to be threadedly connected to the locking seat 14. The locking nut 12 resists the pull ring 16, thereby transmitting the positioning effect to the cleaning plate 7 through the connecting rod 11, thereby avoiding the connecting rod 11 and the cleaning plate 7 from loosening when the step-up transformer is running, affecting the normal operation of the step-up transformer.

[0033] In some specific embodiments, an exhaust filter plate 2 is fixedly connected to the inner wall of the exhaust port 3 , and the exhaust filter plate 2 can filter the exhaust port 3 to prevent dust from entering the metal box 1 .

[0034] In some specific embodiments, a blocking filter plate 6 is fixedly connected to the bottom side of the blocking shell 5, and the blocking filter plate 6 is fixedly connected to the inner wall of the metal box 1. The blocking filter plate 6 can filter the air dust entering from the water outlet 4 to prevent dust from entering the metal box 1 through the exhaust hole 13.

[0035] The above describes several embodiments of the present invention in detail, but the present invention is not limited to these embodiments and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
