Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0029] Please refer to Figures 1-8 The present application provides a technical solution: a heat dissipation side plate of a bus duct, comprising a heat dissipation side plate 1, two sides of the heat dissipation side plate 1 are provided with mounting plates 2, fin plates 3 are slidingly installed on the mounting plates 2, an active cavity 301 is formed in the interior of the fin plates 3, sleeves 4 are slidingly installed in the interior of the fin plates 3, rotating columns 5 are rotatably installed in the interior of the sleeves 4, sliding blocks 6 are connected to the interior of the rotating columns 5 through limiting springs 501, air guide strips 7 are fixedly installed on the sliding blocks 6, electric push rods 8 are fixedly installed in the interior of the rotating columns 5, and extrusion plates 9 are connected to the top end of the electric push rods 8 through rotating assemblies;

[0030] The compressed air blowing assembly is arranged in the interior of the active cavity 301, and is used for blowing dust and dissipating heat for the fin plates 3.

[0031] The extrusion assembly is arranged in the interior of the active cavity 301, and is used for driving the extrusion plates 9 to vibrate.

[0032] As an embodiment of the present application, the rotating assembly comprises an active block 10, one end of the active block 10 is fixedly installed on the top end of the electric push rod 8, the other end of the active block 10 is connected and installed on the extrusion plate 9, and a spiral groove 1001 is formed in the active block 10.

[0033] As an embodiment of the present application, the rotating assembly further comprises a protruding block 11, the protruding block 11 is fixedly installed on the inner wall of the fin plate 3, and one end of the protruding block 11 is arranged in the spiral groove 1001.

[0034] As an embodiment of the present application, the air guide strip 7 is in an inclined shape in the front view, the air guide strip 7 is elastically arranged in the side cavity of the rotating column 5 through the sliding block 6 and the limiting spring 501, and the air guide strip 7 is arranged at equal angles about the center of the rotating column 5.

[0035] After the rotating column 5 moves out of the fin plate 3, the air guide strip 7 is ejected from the rotating column 5 under the action of the limiting spring 501 and the sliding block 6, and the rotating column 5 starts reciprocating rotation through the cooperation of the active block 10 and the protruding block 11 connected by the electric push rod 8, thereby accelerating the gas circulation in the interior of the bus duct and preventing the temperature from being too high to affect the heat dissipation side plate 1.

[0036] As an embodiment of the present application, the compression air blowing assembly comprises a pushing rod 12 movably mounted on the surface of the extrusion plate 9, and a piston plate 13 fixedly mounted on the pushing rod 12.

[0037] As an embodiment of the present application, the surface of the fin plate 3 is uniformly provided with a plurality of protrusions, and the inside of the protrusion of the fin plate 3 is provided with a gas conveying pipe 14, which is symmetric about the horizontal center line of the protrusion. The protrusion of the fin plate 3 is provided with a sliding groove penetrating the movable cavity 301, and the pushing rod 12 is slidably arranged in the sliding groove through the piston plate 13.

[0038] As an embodiment of the present application, the extrusion assembly comprises a limiting block one 15 fixedly mounted on the upper end of the extrusion plate 9, and the limiting block one 15 and a limiting block two 16 are in circular arc shape in front view.

[0039] As an embodiment of the present application, the extrusion assembly further comprises a limiting block two 16 fixedly mounted on the inner wall of the movable cavity 301 at equal intervals, and the limiting block two 16 is located on the movement track of the limiting block one 15.

[0040] The extrusion plate 9 is reciprocated in the movable cavity 301 by the electric push rod 8, and then the pushing rod 12 and the piston plate 13 are moved in the movable cavity 301 by the extrusion plate 9, and the gas is extruded out of the fin plate 3 through the gas conveying pipe 14, and then the surface of the fin plate 3 is cleaned by the blown gas, and at the same time, the extrusion plate 9 is continuously abutted by the limiting block one 15 and the limiting block two 16 during reciprocation, so as to generate vibration and transmit impact force to the fin plate 3, thereby enhancing the dust removal effect.

[0041] Working principle: when the bus duct maintains a high temperature for a long time, the detected temperature sensor starts the electric push rod 8 for the first time through the controller, and the top-out end of the electric push rod 8 pushes the extrusion plate 9 to move along the movable cavity 301 through the air guide strip 7, until the extrusion plate 9 contacts the inner wall of the fin plate 3, at this time the extrusion plate 9 drives the fin plate 3 to move along the sliding groove on the mounting plate 2 under the action of the electric push rod 8, and then the electric push rod 8 reciprocates under the action of the controller;

[0042] With the forward movement of the fin plate 3, the rotating column 5 is moved out of the fin plate 3 and the sleeve 4, and the air guide strip 7 in the rotating column 5 is ejected out of the rotating column 5 under the action of the limiting spring 501 and the sliding block 6. At this time, the movable block 10 fixedly installed on the electric push rod 8 reciprocates under the cooperation of the helical groove 1001 and the protrusion 11, and the electric push rod 8 is rotated to drive the rotating column 5 to rotate synchronously, so that the rotating column 5 rotates in the space formed between the fin plate 3 and the bus duct, accelerates the convection between the internal cold and hot air, improves the overall cooling effect, and prevents the deformation or yield force decrease of the heat dissipation side plate due to long-term adhesion to the high-temperature bus duct.

[0043] In the reciprocating movement of the extrusion plate 9, the movable installed push rod 12 is driven to reciprocate synchronously. In the reciprocating movement of the push rod 12, the push rod 12 extrudes the gas in the movable cavity 301 through the gas delivery pipeline 14 through the piston plate 13, and then blows the gap between the protrusions of the fin plate 3 to cool down, and blows away the dust accumulated on the surface, preventing further accumulation of dust. In the movement of the extrusion plate 9, the limiting block one 15 fixedly installed on the top of the extrusion plate 9 intermittently abuts against the limiting block two 16, so that the extrusion plate 9 vibrates up and down, so that the extrusion plate 9 transmits the impact force generated by the vibration to the fin plate 3, and strengthens the dust removal effect of the fin plate 3 as a whole.

[0044] When the temperature decreases to normal temperature, the electric push rod 8 no longer reciprocates, and pulls the extrusion plate 9 to start moving to the rear side, and drives the fin plate 3 to reset through the extrusion plate 9, and then the rotating column 5 reenters the inner wall of the fin plate 3, and the air guide strip 7 is reextruded into the interior of the rotating column 5 through the fin plate 3 and the inclined sleeve 4.

Any modification, equivalent replacement, improvement, etc. made within the scope of the present application shall be included in the protection scope of the present application.
