At this time, when the driving screw 71 rotates, it can drive the driving bevel gear 2 91 to rotate, so as to drive the reciprocating screw 81.

[0045] like Figure 7 , Figure 8As shown, the cleaning assembly includes four sealing cylinders 111 fixedly mounted on the inner side of the lamp pole 1 below the water tank 5 and distributed in an annular array, the inner side walls of the four sealing cylinders 111 are slidably mounted with piston plates 112, the ends of the four sealing cylinders 111 close to each other are penetrated by push rods 113, and the end of the push rod 113 located on the inner side of the sealing cylinder 111 is fixedly connected to the piston plate 112, a spring 114 is sleeved on the push rod 113, and a transmission wheel 115 is rotatably mounted on the end of the push rod 113 located on the outer side of the sealing cylinder 111, a connecting rod 116 is fixedly mounted on the top surface of the driving bevel gear 91, and a cross rotating leaf 117 corresponding to the transmission wheel 115 is fixedly mounted on the top of the connecting rod 116, and a plurality of linear rotating blades 117 are provided on the bottom surface of the cleaning plate 10 The slots 118 are arranged in an array, and a push plate 119 is slidably installed on the inner side wall of the slot 118. A spring 1110 is fixedly installed between the push plate 119 and the inner top wall of the slot 118. A nozzle 1111 is fixedly installed on the bottom surface of the push plate 119. Connecting pipes are symmetrically provided through the ends of the four sealing cylinders 111 away from the push rod 113, and one-way valves with opposite flow directions are installed inside the two connecting pipes located on the same sealing cylinder 111. One connecting pipe at the end of two sealing cylinders 111 in the four sealing cylinders 111 is connected to the water tank 5, and the other connecting pipe is connected to several nozzles 1111 on both sides. One connecting pipe at the end of the other two sealing cylinders 111 in the four sealing cylinders 111 is respectively connected to several slots 118 on both sides.

[0046] When the driving bevel gear 91 is driven by the driving screw 71, the connecting rod 116 and the cross-rotating blade 117 can be driven to rotate synchronously, so as to push the transmission wheel 115 and the push rod 113 at the end of the sealing cylinder 111, and then the push plate 119 can slide back and forth along the groove 118. At the same time, the water in the water tank 5 can be sprayed out along the nozzle 1111 to clean the advertising light box 3 and the light board at the bottom of the lamp 2, avoid the adhesion of dust, and ensure the brightness of the advertising light box 3 and the light board.

[0047] According to the technical solution provided by the present invention, in the process of daily use, the smart street lamp and the lamp 2 can realize the function of lighting, and the advertising light box 3 can display the advertising curtain. When installing the advertising curtain, the cover plate 12 on the inner side of the inspection port 4 can be removed. At this time, the winding roller 75 and the fixing rod 710 are located at the inspection port 4. The advertising curtain is directly wound on the winding roller 75, and one end of the advertising curtain is connected to the fixing rod 710. After the installation is completed, the rotating wheel 713 can be rotated to drive the bevel gear 1. The meshing of 712 and the transmission bevel gear 1 711 drives the driving screw 71 to rotate. When the driving screw 71 rotates, the threaded sleeve 73 is sleeved on the driving screw 71, and a limit is formed between the positioning rod 78 in the two positioning grooves 77 on the threaded sleeve 73 and the guide column 72. Therefore, the driving screw 71 can drive the threaded sleeve 73, the winding roller 75, the guide block 79 and the fixed rod 710 to move upward. When the threaded sleeve 73 moves to the top of the driving screw 71, the guide block 79 can be inserted into the plug-in frame 85.

[0048] Hold the rotating wheel 713 to fix the driving screw 71, and then rotate the mounting sleeve 910 to move the mounting sleeve 910 vertically upward. At this time, the guide plate 911 can slide upward in the guide port 97, and drive the piston rod 99 to slide to compress the oil in the fixed cylinder 98. When the oil in the fixed cylinder 98 is compressed, it can enter the air bag 96 through the catheter. When the air bag 96 is filled with oil, it can be pushed open and drive the friction plate 95 to slide out along the fixed frame 94. The connecting plate 93 is against the inner side wall of the driving bevel gear 2 91, and the connection between the driving screw 71 and the driving bevel gear 2 91 can be realized. Continue to rotate the rotating wheel 713. At this time, the threaded sleeve 73 can It continues to move upward and can drive the reciprocating screw 81 to rotate synchronously by driving the bevel gear 2 91 and the transmission bevel gear 2 86. When the reciprocating screw 81 rotates, it can drive the plug-in frame 85 and the guide block 79 to move in the direction close to the advertising light box 3. At the same time, the threaded sleeve 73 continues to move upward so that the magnetic sheet between the guide block 79 and the plug-in frame 85 can be connected, and the positioning rod 78 can move out of the positioning groove 77 on the threaded sleeve 73 to release the connection between the positioning rod 78 and the threaded sleeve 73. As the reciprocating screw 81 continues to rotate, the guide block 79 and the fixed rod 710 can slide into the advertising light box 3 so that the advertising curtain on the winding roller 75 is unfolded in the advertising light box 3.

[0049] When it is necessary to replace the advertising curtain, the rotating wheel 713 can continue to rotate to drive the reciprocating screw 81 to rotate. At this time, the rotation of the reciprocating screw 81 can drive the plug-in frame 85 and the guide block 79 to slide in the opposite direction, and the torsion spring 76 can be used to make the unfolded advertising curtain roll up on the winding roller 75. When the plug-in frame 85 moves to the end of the reciprocating screw 81, the positioning rod 78 can be inserted into the positioning groove 77 to achieve reset, and the installation sleeve 910 can be moved downward, and the friction plate 95 can slide in the opposite direction to the connecting disk 93 and separate from the driving bevel gear 2 91. At this time, the rotating wheel 713 can be reversed, and the positioning rod 78 can limit the guide column 72 to make the winding roller 75 and the threaded sleeve 73 move downward to the position of the inspection port 4, so that the advertising curtain can be replaced again.

[0050] As the driving bevel gear 2 91 is driven, the connecting rod 116 and the cross-rotating blade 117 can be driven to rotate synchronously. The four sealing cylinders 111 are grouped in pairs. One of the sealing cylinders 111 in each group is connected to the water tank 5 and the nozzle 1111 through two connecting pipes, and the other sealing cylinder 111 is connected to the slot 118 through a connecting pipe. Under the action of the one-way valves with opposite flow directions in the two connecting pipes on the same sealing cylinder 111, the cross-rotating blade 117 rotates to squeeze the transmission wheel 115, the push rod 113 and the piston plate 112 at the end of each group of sealing cylinders 111 and reset through the spring 114. The slot 118 can be inflated to make the push plate 119 and the nozzle 1111 slide downward, and at the same time, the sealing cylinder 111 can spray the water in the water tank 5 through the nozzle 1111 to rinse and clean the advertising light box 3 and the lamp 2, thereby avoiding the nozzle 1111 extending to affect the brightness of the advertising light box 3 and the lamp 2.
