[0037] After the bridge cover 2 is fixedly covered on the bridge slot housing 1, the bridge cover 2 presses down the lifting plate 13. When the lifting plate 13 descends, the horizontal push rod 15 pushes the horizontal push square column 24 to move horizontally, thereby driving the secondary gear 19 to rotate, and then the vertical rod 21 rotates 90 degrees. The horizontal column 20 is originally distributed in parallel below the protective shell 16, so that the horizontal column 20 will not affect the laying of the cable 3 into the bridge slot housing 1.

The horizontal column 20 is just placed between the two cables 3, that is, Fig.10 The state shown allows ventilation space between the upper and lower cables 3, which is beneficial to the heat dissipation of the cables 3 and ventilation to blow away the heat.

[0038] refer to Fig. 9 It is understood that the wind part 9 includes a square cylindrical shell 25 fixed between the upper bottom plate of the bridge slot shell 1 and the long partition 4, a flat support plate 26 distributed in the square cylindrical shell 25, a fan device 28 and three components 29, and a sub-shaft 27 for establishing a transmission between the fan device 28 and the integrated shaft 11.

[0040] The fan device 28 includes a fan shaft 34 supported at one end of 26, a turntable 36 fixed at the lower end of the fan shaft 34, a plurality of blade groups 37 evenly arranged around the turntable 36, and a ring plate 35 connected to the blade group 37. The ring plate 35 is arranged on the outside of the fan shaft 34. One end of the split shaft 27 is meshingly connected to the annular bevel gear fixed on the fan shaft 34 through a fixed bevel gear, and the other end of the split shaft 27 is meshingly connected to the annular bevel gear fixed on the integrated shaft 11 through a fixed bevel gear. The fan shaft 34 is movably sleeved in the through hole opened on 26.

[0041] The head group 32 includes a pressure shaft 38, a return spring 39, a head frame 40 and a head folding column 41. One end of the head frame 40 is fixed on the long partition 4, and one end of the head folding column 41 slides through the square hole opened on the head frame 40. The other end of the head folding column 41 contacts the deformation rod 10. One end of the return spring 39 is fixed on the head folding column 41, and the other end is fixed on the head frame 40. A row of teeth arranged on the pressure shaft 38 and the head folding column 41 are engaged and transmitted. One end of the pressure shaft 38 is sleeved in the through hole opened on the head frame 40 by setting a shaft body, and the other end of the pressure shaft 38 is vertically fixed to the range extender 31.

[0042] The tail group 30 includes a tail plate 42, a worm 43 and a lifting seat 44. The range extender 31 includes a long plate and an arc-shaped rack fixed at one end of the long plate. The worm 43 is connected to the range extender 31 arc-shaped rack through a fixed cylinder gear. The worm 43 is movably sleeved in a through hole opened on 26, and one end of the tail plate 42 slides through the plate hole opened on 26. An I-shaped lifting seat 44 is fixed to the other end of the tail plate 42. The inner edge of one side of the ring plate 35 is stuck in the lifting seat 44. The tail plate 42 is connected to the helical teeth on the worm 43 by a row of teeth.

[0043] The fan blade group 37 includes a blade plate 45, a blade shaft 46, a block 47, an L-shaped support plate 48 and a follower cylinder 49. The blade plate 45 is fixed to one end of the blade shaft 46, and the other end of the blade shaft 46 is movably sleeved in the follower cylinder 49. The outside of the follower cylinder 49 is fixed to the turntable 36 by setting an arc plate. One end of the L-shaped support plate 48 is meshed and connected with the cylinder gear fixed on the blade shaft 46 by setting a row of teeth, and the L-shaped support plate 48 slides through the plate hole opened on the block 47. One end of the block 47 is fixed to the turntable 36, and the other end of the L-shaped support plate 48 is fixed to the ring plate 35.

[0044] One end of the integrated shaft 11 is externally connected to the motor drive mechanism in the prior art. The integrated shaft 11 rotates to drive a row of fan devices 28 in the device plate cavity to work. Specifically, the integrated shaft 11 drives the sub-shaft 27, and then drives the turntable 36 to rotate through the fan shaft 34, causing the fan blade group 37 to move around, thereby conveying airflow. The outside air enters the square cylinder shell 25 after passing through the air inlet circular hole on the bottom plate of the bridge slot shell 1, and then is injected into the heat dissipation long cavity of the bridge slot shell 1 through the air box 5, flows along the heat dissipation long cavity, and then is discharged through the flat cylinder 6. The heat dissipated during power transmission of the cable 3 is taken away by the flowing air, and the cable 3 can be quickly ventilated and cooled.

[0045] The deformable rod 10 is exposed in the heat dissipation long cavity of the bridge slot housing 1. If the cable 3 generates too much heat unexpectedly, the conventional ventilation and heat dissipation cannot effectively dissipate the heat, and the temperature around the deformable rod 10 rises. The deformable rod 10 expands and deforms and stretches. One end of the deformable rod 10 presses the head folding column 41, and the head folding column 41 translates to drive the pressure shaft 38 to rotate, thereby causing the range extender 31 to swing. Fig.13The swinging state of the range extender 31 is that the worm 43 rotates, and then the tail plate 42 drives the lifting seat 44 to move, and then the ring plate 35 drives all the L-shaped support plates 48 to rise and fall synchronously. Fig.15 The L-shaped support plate 48 in the middle drives the blade shaft 46 to rotate during the rise, causing the blade 45 to flip over. Fig.15 In the flipped state, the blade 45 is in a circular motion, and the angle between the plate surface of the blade 45 and the bottom surface of the turntable 36 is small before the flipping, and the angle becomes larger after the flipping, so that the turntable 36 rotates at a constant speed to drive the fan blade group 37. The flipped blade 45 will cause greater ventilation. At the same time, the workload of the motor driving the entire ventilation work increases. The automatic adjustment and enhanced ventilation mechanism of the present invention requires an increase in the motor workload to support it. Therefore, in the conventional heat dissipation mode, the angle between the surface of the blade 45 and the bottom surface of the turntable 36 is small. When the temperature inside the bridge slot shell 1 is too high, it will cause the deformation rod 10 to deform and elongate. Subsequent adjustment causes the blade 45 to flip itself, thereby automatically enhancing the ventilation.

[0046] 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.
