in the rotating process of the first rotating rod 304, the first belt wheel drives the second belt wheel to rotate through a belt, and then drives the transmission disc 306 to rotate through the second rotating rod 305, so that the lower end of the connecting rod 503 rotates on the front end face of the transmission disc 306, at the moment, the upper end of the connecting rod 503 drives the fixing rod 502 and the two blockage cleaning brushes 501 to reciprocate up and down, and impurities blocked in meshes of the sound outlet mesh cover 103 can be cleaned through the up and down reciprocating movement of the two blockage cleaning brushes 501;
when the display screen main body 6 needs to be maintained, firstly, the sealing door 102 is opened, then the display screen main body 6 is pulled towards the right side, so that the display screen main body 6 slides rightwards from the inside of the shell 1 to the right side outside the shell 1, then the display screen main body 6 can be maintained, and the display screen main body 6 can obtain an effective limiting effect when sliding rightwards through the matching of the limiting sliding column 602 and the strip-shaped notch 106;
when raining outdoors, rainwater is collected through the rainwater collection box 2, then rainwater entering the rainwater collection box 2 flows into the T-shaped sewer pipe 701 through a water outlet pipe at the bottom of the rear side of the rainwater collection box 2, then the rainwater flowing downwards drives the hydraulic wheel 705 to rotate, so that the driving shaft 704 drives the worm to rotate, and then the vertical transmission shaft 702 is driven to rotate through the worm wheel, so that the belt wheel A703 drives the belt wheel B805 to rotate through a belt, so that the reciprocating screw rod 803 rotates, and then the screw rod nut 804 drives the cleaning brush 802 to move up and down in a reciprocating mode under the action of a thread groove on the reciprocating screw rod 803, so that sundries blocked in meshes of the rear end face of the ventilation mesh enclosure 104 are cleaned, and further the ventilation efficiency of the ventilation holes is prevented from being influenced.
Finally, it should be noted that, when describing the positions of the components and the matching relationship therebetween, the present invention is usually illustrated by one/a pair of components, however, it should be understood by those skilled in the art that such positions, matching relationship, etc. are also applicable to other/other pairs of components.
The above description is intended to be illustrative of the present invention and not to limit the scope of the invention, which is defined by the claims appended hereto.
