The linkage gears 303 are rotatably installed on both sides of the mounting seat 301, and the pin sleeve 304 is fixedly installed on the top of the linkage gear 303. The mounting frame 1 is installed on both sides of the top of the seat 301 through the pin sleeve 304, and the mounting frame 1 includes two assembly frames A101, two assembly frames B102, an LED screen 103, a threaded rod 104, a threaded sleeve 105, and a latch shaft 106.

A slot head is fixedly installed on one end of the threaded rod 104, which is connected to the slot head through an assembly tool, and the threaded rod 104 is driven to rotate and threadedly connected with the threaded sleeve 105 by rotating the slot head, so as to complete the rapid assembly of the two assembly racks A101 and the two assembly racks B102. At the same time, when disassembling the installation frame 1, the threaded rod 104 is rotated in the reverse direction to separate the threaded sleeve 105, so as to realize the rapid disassembly of the installation frame 1. The disassembled installation frame 1 is convenient for transportation, and it is also convenient for replacing partially damaged parts, which not only reduces the difficulty of maintenance and replacement, but also reduces the maintenance and replacement cost.

[0036] The transmission gear rod 306 is composed of a transmission rod and a gear assembly, and the transmission rod passes through the bevel gear set 305 and is fixedly connected. The gear assembly is meshed with the transmission gear 307. When the servo motor 302 is powered on, the transmission gear rod 306 is driven to rotate the linkage gear 303 through the bevel gear set 305. The rotating transmission gear rod 306 drives the screw rod 308 to rotate through the meshing transmission gear 307. The rotating screw rod 308 drives the two sets of linkage gears 303 to rotate relative to each other. The relatively rotating linkage gears 303 are connected to the pin shaft through the pin sleeve 304. The rod 106 cooperates to drive the two groups of mounting frames 1 to rotate relative to each other until the front faces are relatively closed, thereby protecting the two groups of LED screens 103 inside the closed mounting frames 1, improving the protection effect of the LED screens 103, and allowing the mounting frames 1 to automatically protect the LED screens 103 in severe weather, thereby solving the problem that the LED screens 103 are easily damaged by severe weather, thereby ensuring the safety of the LED screens 103 in severe weather. At the same time, the closed mounting frames 1 can reduce the wind-exposed area, thereby improving the wind-resistant effect of the mounting frames 1.

[0037] Furthermore, the two assembly racks A101 and the two assembly racks B102 are both penetrated with threaded rods 104, and one end of the two assembly racks A101 and the two assembly racks B102 are both embedded with threaded sleeves 105. The two assembly racks A101 and the two assembly racks B102 are threadedly assembled into a closed whole by the threaded rods 104 and the threaded sleeves 105 to fix the LED screen 103, wherein a latch shaft 106 is fixedly installed on one side of the bottom of the assembly rack B102 at the bottom of the LED screen 103, and the latch shaft 106 extends to the inside of the pin sleeve 304 for insertion;

[0038] It should be noted that: the two assembly racks A101 are respectively located at the two ends of the assembly rack B102, and the threaded rod 104 is driven to rotate by rotating the slot head to be threadedly connected to the threaded sleeve 105, the LED screen 103 is placed between the two assembly racks A101 and on the top of the assembly rack B102, and then another assembly rack B102 is placed on the top between the two assembly racks A101, and the threaded rod 104 is driven to rotate by rotating the slot head to be threadedly connected to the threaded sleeve 105, to complete the rapid assembly of the two assembly racks A101 and the two assembly racks B102.

[0039] Furthermore, a reciprocating screw rod 202 is rotatably installed inside the vertical pipe 201, a positioning pin seat 206 extending to the inside of the mounting seat 301 is fixedly installed at the bottom of the reciprocating screw rod 202, and an electric rod 207 is fixedly installed at the top of the mounting seat 301, and the output end of the electric rod 207 extends into the positioning pin seat 206;

[0040] It should be noted that when the electric rod 207 is powered on and the output end thereof moves back and forth horizontally, when the output end of the electric rod 207 extends to the inside of the positioning pin seat 206, the reciprocating screw rod 202 can be positioned to prevent the reciprocating screw rod 202 from moving on its own, thereby achieving the purpose of automatically controlling the rotation of the reciprocating screw rod 202.

[0041] Furthermore, a fan blade 203 is fixedly installed on the top of the reciprocating screw rod 202 through a connecting rod, and a Hall sensor is sleeved on the outer side of the connecting rod, a thread sleeve seat 208 is sleeved on the outer side of the reciprocating screw rod 202, a shaft seat 205 is fixedly installed on the front side of the thread sleeve seat 208, a cleaning rod 204 is installed inside the shaft seat 205 through a shaft bolt, a reset spring 209 is fixedly installed on the back side of one end of the cleaning rod 204, and one end of the reset spring 209 is fixedly installed on one side of the front side of the shaft seat 205;

[0042] It should be noted that: a FT-WQX6 meteorological sensor is fixedly installed on the top of the connecting rod, and the external environment can be monitored by the FT-WQX6 meteorological sensor. The number of rotations of the reciprocating screw 202 is monitored by the Hall sensor. The position of the cleaning rod 204 is calculated by monitoring the number of rotations of the reciprocating screw 202. A rubber pad is installed on the back of the cleaning rod 204, and the rubber pad is in contact with the front of the LED screen 103. When the cleaning rod 204 moves up and down, the front of the LED screen 103 is cleaned by the rubber pad.

[0043] Further, a servo motor 302 is fixedly installed inside the mounting seat 301, a bevel gear set 305 is fixedly installed at the output end of the servo motor 302, a transmission gear rod 306 is fixedly installed at one end of the top of the bevel gear set 305, a transmission gear 307 is meshedly installed at the top of one end of the transmission gear rod 306, a spiral rod 308 is fixedly installed on the front of the transmission gear 307, and both sides of the spiral rod 308 are engaged with the linkage gear 303;

[0044] It should be noted that: a controller is fixedly installed on one side of the inner part of the mounting base 301, and the controller is electrically connected to the FT-WQX6 model meteorological sensor, the Hall sensor, the servo motor 302, and the electric rod 207 through wires. The servo motor 302 is energized to drive the transmission gear rod 306 to rotate the linkage gear 303 through the bevel gear group 305. The rotating transmission gear rod 306 drives the screw rod 308 to rotate through the meshing transmission gear 307. The rotating screw rod 308 drives the two sets of linkage gears 303 to rotate relative to each other. The relatively rotating linkage gears 303 cooperate with the pin shaft 106 through the pin sleeve 304 to drive the two sets of mounting frames 1 to rotate relative to each other until the front sides are relatively closed.

[0045] Further, a lifting support column 4 is fixedly installed at the bottom of the driving mechanism 3, and the lifting support column 4 includes a column 401, a lifting column 402, a lifting rack 403, and a lifting gear 404. The lifting column 402 is movably installed inside the column 401, and the lifting rack 403 is fixedly installed on one side of the lifting column 402. The lifting gear 404 is rotatably installed on one side of the top of the column 401, and the lifting gear 404 is meshed and connected with the lifting rack 403;

[0046] It should be noted that: the lifting column 402 is driven to move vertically by rotating the lifting gear 404 through the meshing connection with the lifting rack 403, and the vertically moving lifting column 402 drives the installation frame 1 to move up and down through the driving mechanism 3, so as to adjust the height of the LED screen 103 according to the height installation requirements.

[0047] Furthermore, a mounting plate 5 is fixedly installed at the bottom of the lifting support column 4, and an anchor rod 501 is installed through the interior of the mounting plate 5;

[0048] It should be noted that through holes are equidistantly provided inside the mounting plate 5 , and the anchor rods 501 extend through the through holes to the ground. The mounting plate 5 is firmly fixed to the ground by the anchor rods 501 , thereby ensuring the stability of the device installation.

[0049] Further, a positioning mechanism 6 is fixedly installed at the bottom of the mounting plate 5, and the positioning mechanism 6 includes a positioning rod 601, a rack rod 602, a gear member 603, a flip gear 604, and a positioning claw 605. The interior of the positioning rod 601 is movably installed with a rack rod 602 extending to the interior of the lifting support column 4. The rack rod 602 is assembled by a mounting rod and two gear rods, and the two gear rods are respectively fixed at both ends of the mounting rod. The interior of the positioning rod 601 is equidistantly installed with positioning claws 605 through a shaft member, and the bottom of the positioning claw 605 is fixedly installed with a flip gear 604, and the inner side of the flip gear 604 is meshed with the gear rod.

[0050] It should be noted that the rotating gear member 603 drives the meshing rack rod 602 to move downward, and the downwardly moved rack rod 602 drives the flipping gear 604 to drive the positioning claw 605 to flip outward, and the flipped positioning claw 605 is inserted horizontally into the foundation, thereby increasing the gripping area of ​​the positioning rod 601.

[0051] Working principle: Before using the device, the user should first inspect the device and use it after confirming that there is no problem. Insert the positioning rod 601 into the foundation, and the rotating gear 603 drives the meshing rack rod 602 to move downward. The downwardly moved rack rod 602 drives the flip gear 604 to drive the positioning claw 605 to flip outward. The flipped positioning claw 605 is inserted into the foundation horizontally, which increases the gripping area of ​​the positioning rod 601.

[0052] The lifting column 402 is driven to move vertically by rotating the lifting gear 404 and meshing with the lifting rack 403. The vertically moving lifting column 402 drives the installation frame 1 to move up and down through the driving mechanism 3, so as to adjust the height of the LED screen 103 according to the height installation requirements;

[0053] The external environment can be monitored by the FT-WQX6 meteorological sensor, and the monitoring electrical signal can be transmitted to the controller for calculation. When the controller calculates that the monitoring electrical signal reaches the protection set value, the controller controls the servo motor 302 to be powered on. The servo motor 302 is powered on to drive the transmission gear rod 306 to rotate the linkage gear 303 through the bevel gear group 305. The rotating transmission gear rod 306 drives the screw rod 308 to rotate through the meshing transmission gear 307. The rotating screw rod 308 drives the two groups of linkage gears 303 to rotate relative to each other. The relatively rotating linkage gears 303 cooperate with the pin sleeve 304 and the latch shaft 106 to drive the two groups of installation frames 1 to rotate relative to each other until the front faces are relatively closed, so that the two groups of LED screens 103 are protected inside the closed installation frame 1, so that the installation frame 1 automatically protects the LED screen 103 in bad weather. At the same time, the closed installation frame 1 can reduce the wind-exposed area, thereby improving the wind resistance of the installation frame 1.

[0054] The cleaning time is set by the controller, and the electric rod 207 is controlled to be powered on and run according to the set cleaning time. When the LED screen 103 needs to be cleaned, the controller controls the electric rod 207 to be powered on and run, and the output end moves horizontally out of the positioning pin seat 206 to unlock the reciprocating screw rod 202. The fan blade 203 is used to drive the reciprocating screw rod 202 to rotate under the action of wind force. The rotating reciprocating screw rod 202 drives the shaft seat 205 to move vertically through the wire sleeve seat 208. The vertically reciprocating shaft seat 205 drives the cleaning rod 204 to move. When the cleaning rod 204 moves up and down, the front of the LED screen 103 is cleaned through the rubber pad. At the same time, the number of rotations of the reciprocating screw rod 202 is monitored by the Hall sensor, and the detection electrical signal is transmitted to the controller for calculation. The controller calculates the position of the cleaning rod 204 by monitoring the number of revolutions of the reciprocating screw 202. When the cleaning rod 204 reaches the set position after cleaning, the controller controls the electric rod 207 to be energized and the output end moves horizontally to the inside of the positioning pin seat 206, so as to position the reciprocating screw 202 and prevent the reciprocating screw 202 from moving on its own, thereby ensuring that the cleaning rod 204 is reset after the cleaning work is completed. The reset spring 209 can be used to drive the cleaning rod 204 to rotate inward when the mounting frame 1 is rotated and closed, and the rotating cleaning rod 204 stretches the reset spring 209. When the mounting frame 1 is rotated and expanded, the cleaning rod 204 uses the elastic reset force of the reset spring 209 to reset to the expanded state, so that the rubber pad on the back of the cleaning rod 204 fits against the front of the LED screen 103.
