The connecting plate 5 drives the lamp beads 7 and the spare lamp beads 8 to move upwards, when the air bags 20 expand and lengthen, the push plate 18 can be pushed to move, so that the springs 19 are compressed, the push plate 18 pushes the transmission rod 9 and the connecting plate 5 to move rightwards through the rollers 13, when the clockwise rotation angle of the transmission rod 9 exceeds 45 degrees, the connecting plate 5 can automatically rotate clockwise under the influence of the gravity center, the baffle 12 finally contacts with the right side of the fan-shaped groove 11, namely the transmission rod 9 rotates 90 degrees clockwise, the spare lamp beads 8 are located right above the through holes 4, and then the spare lamp beads 8 can be replaced and installed at the positions of the original lamp beads 7 through the downward movement of the fixing plates 10 driven by the air cylinders 15, and after the installation of the spare lamp beads 8, the lamp covers 3 are cleaned through the elastic pneumatic mechanism.
It should be noted that, the hose 24 is located inside the U-shaped member 25, the compression bar 14 is disposed under the hose 24, the bottom end of the compression bar 14 is fixedly connected to the fixing plate 10, and the compression bar 14 is disposed corresponding to the U-shaped member 25. After the plunger 14 moves up a certain distance, the plunger 14 and the U-shaped member 25 can compress the hose 24, and the air flow cannot pass through the hose 24 because the hose 24 is compressed, so that the air bag 20 is inflated.
The working principle and the using flow of the invention are as follows: fig. 1 to 6 are all initial states of the device, wherein the lamp beads 7 are positioned inside the lampshade 3; as shown in fig. 4, the baffle 12 is positioned at the left side of the fan-shaped groove 11, the air bag 20 is not inflated to be long, and the push plate 18 is positioned at the left side of the slide bar 17;
when the heat generated by the lamp beads 7 in the lamp shades 3 is cooled, the air conditioner 29 is started to generate cold air, the cold air enters the air bag 20 beside the first lamp shade 3 through the air inlet pipe 27, continuously enters the interior of the lamp shade 3 through the telescopic air pipe 23, the hose 24 and the second air pipe 26, and the air is discharged into the air bag 20 beside the next lamp shade 3 from the interior of the lamp shade 3 through the first air pipe 22, so as to circulate, finally enters the last lamp shade 3 and is discharged to the outside of the shell 1 through the air outlet pipe 28. The heat generated by the lamp beads 7 is brought to the outside during the process of passing the cool air through the plurality of lamp covers 3;
when a certain lamp bead 7 breaks down, the starting cylinder 15 drives the fixing plate 10 to move upwards, the fixing plate 10 drives the pressing rod 14 to move upwards, the fixing plate 10 drives the connecting plate 5 to move upwards through the transmission rod 9, and the connecting plate 5 drives the lamp bead 7 and the standby lamp bead 8 to move upwards. As shown in fig. 7, when the pressing bar 14 contacts the bottom of the hose 24, the roller 13 also just contacts the side of the push plate 18 in a rolling manner, and the lamp beads 7 are separated from the lamp housing 3 and have a certain distance. The plunger 14 is then moved upwardly a further distance which causes the plunger 14 to compress the hose 24 and then close the cylinder 15. Because the hose 24 is pressed and the air flow cannot pass through the hose 24, but the air conditioner 29 is continuously injecting the air, the air can expand the air bag 20 to be long, as shown in fig. 4, the air bag 20 is lengthened to push the push plate 18 to move rightwards, the spring 19 is compressed, the push plate 18 pushes the transmission rod 9 and the connecting plate 5 to move rightwards through the roller 13, when the clockwise rotation angle of the transmission rod 9 exceeds 45 degrees, the connecting plate 5 is automatically rotated clockwise under the influence of the gravity center, and finally the baffle 12 is contacted with the right side of the fan-shaped groove 11, namely, the transmission rod 9 is rotated 90 degrees clockwise, and the spare lamp beads 8 are positioned right above the through holes 4. Then, the air cylinder 15 is started to drive the fixed plate 10 to move downwards, the fixed plate 10 drives the connecting plate 5 to move downwards through the transmission rod 9, the connecting plate 5 drives the lamp beads 7 and the standby lamp beads 8 to move downwards, and when the standby lamp beads 8 enter the lamp shade 3 through the through holes 4, the air cylinder 15 is closed;
when the fixing plate 10 drives the compression bar 14 to move downwards and not press the hose 24, the air flow is not blocked when passing through the hose 24, and the push plate 18 moves leftwards under the action of the spring 19, so that the air bag 20 is shortened, and finally the push plate 18 moves to the initial position, so that the air bag 20 is restored to the initial state. During the shortening of the air bag 20, the air in the air bag 20 may enter the lampshade 3 through the telescopic air pipe 23, the hose 24 and the second air pipe 26, and the air speed of the part is high. The spare lamp beads 8 have not yet entered the lamp housing 3 and are at a distance from the through holes 4, i.e. the through holes 4 are open. So this part of higher speed gas gets into in the lamp shade 3, can strike the inside dust of lamp shade 3, makes the dust outside the lamp shade 3 along with the air current is discharged through the through-hole 4, and then plays the effect of dust clearance to the inside of lamp shade 3, makes the light irradiation effect better. At the same time, the part of the gas with higher speed can quickly restore the hose 24 to the initial state when passing through the hose 24;
when both the lamp bead 7 and the spare lamp bead 8 fail, the shell 1 needs to be disassembled, the lamp bead 7 and the spare lamp bead 8 are replaced, and the connecting plate 5 is manually rotated by 90 degrees anticlockwise, namely, the device is debugged to an initial state.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
