[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Embodiment 1:

[0026] See also Figure 1-6 In this embodiment, a ventilation and dust prevention mechanism for an outdoor box-type substation includes a box-type substation 1, on which two ventilation components 2 are arranged. The ventilation components 2 are arranged so that the interior of the substation can be effectively ventilated during use, thereby effectively avoiding the situation in which the internal temperature of the substation is too high and the internal power equipment is damaged.

[0027] In order to achieve the effect of ventilation inside the substation, the ventilation component 2 in this embodiment is provided with a first fan 21, one end of the first fan 21 is fixedly connected to an air inlet pipe 22, the other end of the air inlet pipe 22 is fixedly connected to a ventilation pipe 23, the other end of the ventilation pipe 23 is fixedly connected to an exhaust pipe 24, and the other end of the exhaust pipe 24 is fixedly connected to a second fan 25; by providing the first fan 21 and the second fan 25, it is possible to effectively achieve the effect of gas exchange between the inside of the substation and its outside, thereby ensuring that it can achieve a good heat dissipation effect inside the substation.

[0028] The first fan 21 and the second fan 25 are both provided with a transmission motor 26, the output shafts of the two transmission motors 26 are both fixedly connected to a fan 27, a transmission rod 28 is fixedly connected to the top of one fan 27, and the other end of the transmission rod 28 is fixedly connected to a transmission boss 29; in actual use, the staff can control the two transmission motors 26 to make the rotation directions of the fans 27 in the first fan 21 and the second fan 25 consistent, that is, the external air enters through the first fan 21 and then is discharged through the second fan 25. At this time, the air in the box-type substation 1 can be discharged from the second fan 25 through the ventilation pipe 23, achieving the effect of ventilation and air exchange. When the staff controls the transmission motor 26 to drive the fan 27 in the second fan 25 to rotate, the fan 27 can drive the transmission rod 28 to rotate, so that the transmission rod 28 can drive the transmission boss 29 to cause the cleaning component 3 to produce a displacement effect.

[0029] A support rod 221 is provided on the air inlet pipe 22, a return spring 222 and two guide posts 223 are provided on the support rod 221, the two guide posts 223 are slidably connected with the cleaning assembly 3, and the other end of the return spring 222 is fixedly connected to the cleaning assembly 3. In the actual use process, the guide post 223 can play a good supporting and guiding effect, and the return spring 222 can play an effect of resetting the cleaning assembly 3. An air inlet groove 231 is provided on the ventilation pipe 23, and a filter screen 232 is provided in the ventilation pipe 23. This arrangement can play a good cleaning effect on the filter screen 232 provided in the ventilation pipe 23 through the cleaning assembly 3 during use, avoiding the occurrence of blockage.

[0030] Embodiment 2:

[0031] See also Figure 1-6In order to achieve the effect of automatic cleaning of the ventilation pipe 23, three support rings 31 are arranged on the cleaning assembly 3 in this embodiment, and connecting rods 32 are fixedly connected between the three support rings 31. A driven boss 33 is arranged on the right side of a support ring 31, and the driven boss 33 is transmission-connected with the transmission boss 29. By maintaining the transmission connection between the driven boss 33 and the transmission boss 29, when the staff controls the transmission boss 29 to rotate, the transmission boss 29 can drive the driven boss 33 to produce a displacement effect, and in the process of the displacement of the driven boss 33, the three support rings 31 can be driven to produce a displacement effect. Cleaning brushes 34 are fixedly connected to the outer circumferential surface of the support ring 31, and the cleaning brushes 34 are kept in contact with the filter 232. When the three support rings 31 are displaced, the cleaning brushes 34 can play a cleaning effect on the filter 232. By arranging a mounting plate 35 in a support ring 31 away from the driven boss 33, two connecting holes 36 are opened on the mounting plate 35, the two connecting holes 36 are slidably connected with the two guide posts 223, and the return spring 222 is fixedly connected with the mounting plate 35, so that it can be more stable during the displacement process.

[0032] The working principle of the above embodiment is:

[0033] 1. When the substation needs to be ventilated, during use, the staff can first control the two transmission motors 26 to make the rotation directions of the fans 27 in the first fan 21 and the second fan 25 consistent, that is, the external air enters through the first fan 21 and then is discharged through the second fan 25. At this time, the external air will enter the box-type substation 1 from the air inlet slot 231. During the process of the external air entering, the filter 232 can intercept the dust and debris in the air. Similarly, the air in the box-type substation 1 can enter the exhaust pipe 24 through the air inlet slot 231 and be discharged from the second fan 25, achieving the effect of ventilation and air exchange.

[0034] 2. During ventilation, when the staff controls the transmission motor 26 on the second fan 25 to drive the fan 27 to rotate, the protruding portion of the transmission boss 29 will contact the protruding portion of the driven boss 33, which will drive the driven boss 33 to move. During the displacement of the driven boss 33, the three support rings 31 can be driven to move. When the three support rings 31 are displaced, the cleaning brush 34 can clean the filter 232. At the same time, the support ring 31 will drive the mounting plate 35 to compress the reset spring 222. When the protruding portion of the transmission boss 29 leaves the protruding portion of the driven boss 33, the reset spring 222 will drive the support ring 31 to reset it, so that it can reciprocate. When the fan 27 continues to rotate, it can drive the cleaning brush 34 to continuously clean the filter 232.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
