TECHNICAL FIELD
[0001] The present application relates to the technical field of oil-immersed transformers, in particular to a dust-removing and cooling integrated outdoor transformer. BACKGROUND
[0002] The oil-immersed transformer operating outdoors is exposed to the complex environment of wind and sand, dust and the like for a long time, and dust and the like is easy to adhere to the surface of the heat dissipation component, resulting in a decrease in cooling efficiency. Moreover, the surface temperature of the heat dissipation pipe of the oil-immersed transformer is between 60 DEG C and 85 DEG C when the oil-immersed transformer is under load. The continuous high temperature of 60 DEG C on the surface of the heat dissipation pipe causes the organic matter (such as plant fibers, pollen, microorganisms and the like) in the dust to gradually carbonize, forming black stubborn stains that are difficult to clean.
[0003] Therefore, the existing ones mostly adopt the mode of installing a dust-removing system (such as a filter screen) on the outside of the radiator to block dust. Since the surface of the heat dissipation pipe is in a continuous high temperature state for a long time, and there are many uncertain factors in the working environment of the outdoor oil-immersed transformer, in order to reduce the damage of the filter screen caused by accidental factors, the filter screen made of metal material becomes the best choice. In order to intercept wind and sand, dust and the like, the mesh aperture of the filter screen needs to reach microns (such as 10-50 mu m), and the metal filter screen is difficult to weave, and the filter screen is also easy to be blocked by wind and sand, dust and the like, affecting air circulation and reducing cooling efficiency. The existing cleaning of the blocked filter screen mostly adopts the mode of knocking, which is harmful to the filter screen and also easy to cause the change of the aperture, which is not conducive to the long-term use of the filter screen.

DETAILED DESCRIPTION
[0036] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.
[0037] Please refer to Figures 1-13 The present application provides a technical solution: a dust removal and cooling integrated outdoor transformer, comprising a transformer body 1 and a radiator 2 mounted on the side of the transformer body 1; the radiator 2 is provided with a filtering unit on both sides; a wind guiding unit is arranged between the two filtering units; the wind guiding unit can realize back blowing cleaning of the filtering unit through autorotation; the filtering unit comprises two mounting frames 5, two filter screens 6 and a driving mechanism; the two mounting frames 5 are arranged on the side of the radiator 2; the two mounting frames 5 are hingedly connected through a hinge 7; the mounting frame 5 close to the side of the radiator 2 is connected with the transformer body 1 through a guide mechanism; the two filter screens 6 are fixedly connected with the two mounting frames 5 respectively; the two filter screens 6 are mutually adhered, and the mesh holes are arranged in a staggered manner; the driving mechanism is arranged on the side of the mounting frame 5, and is used for driving the relative rotation of the two mounting frames 5.
[0038] Reference Figure 1 , Figure 1 In the figure, X indicates the front side, and Y indicates the rear side; with reference Figure 5 and Figure 7 , a and b represent two filter screens 6, the mesh holes of the two filter screens 6 are arranged in a staggered manner, and are mutually adhered, so as to reduce the size of the mesh holes of the filter screen 6, improve the dust interception efficiency, the mesh hole of a single filter screen 6 is slightly larger than the actual interception precision, which can reduce the manufacturing cost and difficulty of the filter screen 6; for example Figure 1As shown, in the initial state, the air flow is from front to back side under the driving of the air guide unit, at this time, the filter unit on the front side plays a role in intercepting dust, and the airflow can realize back blowing to the filter unit on the back side, so as to blow off the dust adhered to the surface of the filter screen 6 of the filter unit on the back side; on the contrary, when the air flow is from back to front side under the driving of the air guide unit, the filter unit on the back side plays a role in intercepting dust, and the airflow blows off the dust adhered to the surface of the filter screen 6 of the filter unit on the front side; referring to Figure 11 , when it is needed to clean the dust adhered to the surface of the filter screen 6, the driving mechanism drives the mounting frame 5 away from the heat dissipation device 2 to rotate clockwise to the state shown in Figure 11 , at this time, the two filter screens 6 are staggered, and the dust, particulate matter and the like clamped in the mesh holes of the two filter screens 6 can be separated from the mesh holes due to the increase of the mesh holes, and at the same time, fall outward under the action of the airflow; after the dust adhered to the surface of the filter screen 6 is cleaned, the driving mechanism drives the mounting frame 5 away from the heat dissipation device 2 to rotate counterclockwise back to the initial state shown in Figure 9 ; it should be noted that since the mounting frame 5 is located at the side of the heat dissipation device 2, the ambient temperature thereof is slightly lower than the surface temperature of the heat dissipation device 2, but the temperature thereof is relatively high, if the two mounting frames 5 adopt a horizontal sliding separation mode, the material will be expanded after being heated, which will reduce the horizontal sliding gap, resulting in reduced sliding smoothness; therefore, the two mounting frames 5 are hinged through the hinge 7, and the hinged mode can avoid the difficulty in resetting due to the expansion of the material caused by heating.
[0039] Specifically, as shown in Figure 4 , Figure 5 and Figure 6 , the driving mechanism comprises a gas cylinder 10, a fixed block 11 and a reset spring 14; the gas cylinder 10 is arranged below the mounting frame 5, and the output end thereof is fixedly connected with a push rod 13; the fixed block 11 is fixedly installed at the bottom of the mounting frame 5 away from the heat dissipation device 2; the push rod 13 is located at the side of the fixed block 11, and can drive the fixed block 11 to move; the reset spring 14 is connected with the two mounting frames 5 at both ends thereof; when the output end of the gas cylinder 10 extends outward, the fixed block 11 can be driven to move away from the heat dissipation device 2 through the push rod 13; at this time, the mounting frame 5 away from the heat dissipation device 2 rotates outward, and the reset spring 14 is stretched; after the dust and the like on the surface of the filter screen 6 falls off, the output end of the gas cylinder 10 is retracted towards the heat dissipation device 2, and the mounting frame 5 moves back to the initial state under the elastic force of the reset spring 14, and the two filter screens 6 are in the state of abutting.

[0041] Specifically, as shown, Figure 8 As shown, the sliding block one 12 is installed with the ball 15 at the bottom, when the push rod 13 is disengaged from the sliding block one 12, and the mounting frame 5 rotates to the initial position on the side close to the radiator 2 under the elastic force of the reset spring 14, the ball 15 can convert the sliding friction between the sliding block one 12 and the push rod 13 into rolling friction, so that the mounting frame 5 can be reset more smoothly.
