[0035] The fixed box 2 is internally rotatably connected with four rotating shafts 3. The four rotating shafts 3 all rotate through the fixed box 2 and extend to one side of the fixed box 2. The four rotating shafts 3 extending to the outside of the fixed box 2 are fixedly installed with drive blades 4. The four rotating shafts 3 are located at one end inside the fixed box 2 and are fixedly installed with eccentric wheels 15. A motor 28 is fixedly installed inside the fixed box 2, and the output end of the motor 28 is fixedly connected to one of the rotating shafts 3. Sprockets 26 are fixedly sleeved on the two rotating shafts 3, and chains 27 are transmission-connected to the two sprockets 26. The four rotating shafts 3 are transmission-connected through three sets of sprockets 26 and chains 27.

[0036] The motor 28 is started, and the motor 28 drives one of the rotating shafts 3 to rotate, and then drives the four rotating shafts 3 to rotate through multiple sets of sprockets 26 and chains 27, and then the four eccentric wheels 15 rotate, and then the four eccentric wheels 15 squeeze the piston 14, and then the piston 14 slides inside the fixed box 2, and then when the piston 14 moves upward, the fixed column 23 moves upward, and the fixed column 23 slides inside the limiting plate 24, and the fixed column 23 squeezes the return spring 25. Pressure is applied, and the gas inside the fixed box 2 enters the inside of the air outlet pipe 5, so that the one-way valve 13 inside the air outlet pipe 5 is opened, and the one-way valve 13 on the fixed box 2 is closed, so that the gas inside the fixed box 2 is discharged through the air outlet pipe 5, and the air outlet pipe 5 blows air to the connection between the curtain wall outer frame 1 and the glass, thereby quickly drying it, preventing water from accumulating in the gap, minimizing the erosion of moisture on the sealant, preventing penetration, reducing water leakage, and preventing water from flowing into the interior of the visitor center and dripping on tourists.

[0037] When the eccentric wheel 15 is no longer pressing the piston 14, the piston 14 and the fixed column 23 will be reset by the elastic force of the reset spring 25, and then the piston 14 will move upward, thereby closing the one-way valve 13 inside the outlet pipe 5 and opening the one-way valve 13 on the fixed box 2, and injecting air into the fixed box 2.

[0038] By disposing the driving blades 4, when the wind blows the driving blades 4, the driving blades 4 drive the rotating shaft 3 to rotate, thereby assisting in driving the rotating shaft 3 to rotate and reducing energy consumption.

[0039] A water inlet 6 is provided on one side of the fixed box 2, and the water inlet 6 is connected to the interior of the fixed box 2. A suspension rod 16 is fixedly installed on the bottom of the piston 14, and an extrusion block 19 is fixedly installed on the bottom of the suspension rod 16. The shape of the lower end of the extrusion block 19 is inclined, and a fixed outer rod 18 is fixedly installed inside the fixed box 2. The interior of the fixed outer rod 18 is slidingly connected with an extrusion plate 17, and the interior of the fixed outer rod 18 is fixedly installed with an elastic spring 20. One end of the elastic spring 20 close to the extrusion plate 17 is fixedly connected to the extrusion plate 17, and a first cleaning guide rod 12 is fixedly installed on one side of the extrusion plate 17. The first cleaning guide rod 12 is located inside the water inlet 6.

[0040] When the piston 14 moves upward, the suspension rod 16 and the extrusion block 19 will move upward, so that the extrusion block 19 will no longer squeeze the extrusion plate 17, and the extrusion plate 17 will be reset by the elastic force of the elastic spring 20, so that the first cleaning guide rod 12 will move toward the inside of the fixed box 2. When the piston 14 is reset, the inclined surface of the bottom of the extrusion block 19 will squeeze the upper end of the extrusion plate 17, so that the extrusion plate 17 will slide toward the inside of the fixed outer rod 18, and then the elastic spring 20 will be squeezed, so that the first cleaning guide rod 12 will move toward the inside of the water inlet 6, so as to facilitate the extrusion of impurities inside the water inlet 6, prevent impurities from accumulating inside the water inlet 6, causing the water inlet 6 to be blocked, facilitate drainage, and prevent corrosion of the sealant.

[0041] A second cleaning guide rod 21 is fixedly installed inside the piston 14 , a drainage hole 22 is opened at the bottom of the fixed box 2 , and the second cleaning guide rod 21 is slidably connected inside the drainage hole 22 .

[0042] When the piston 14 moves up and down, the second cleaning guide rod 21 will follow the piston 14 to move up and down, thereby facilitating the dredging of the drainage hole 22 through the second cleaning guide rod 21, thereby preventing impurities from accumulating inside the drainage hole 22 to the greatest extent, causing water to accumulate inside the fixed box 2, and maximizing the discharge effect.

[0043] Square rods 10 are slidably connected to both sides of the fixed box 2, and connecting plates 9 are fixedly installed on the opposite ends of the two square rods 10.

[0044] Pull the two connecting plates 9 to move the two connecting plates 9 away from each other, so that the two square rods 10 slide inside the fixed box 2, stretch the two tension springs 11, and thus disengage the two clamping blocks 8 from the inside of the two clamping slots 7, and then remove the fixed box 2 from the curtain wall outer frame 1. During installation, the two clamping blocks 8 are installed inside the two clamping slots 7 to fix the fixed box 2, making it easier to install and fix the fixed box 2, and improving the convenience of installing and fixing the fixed box 2.

[0045] A method for preventing penetration of an exposed frame curtain wall comprises the following steps: starting a motor 28, causing the motor 28 to drive one of the rotating shafts 3 to rotate, and then driving the four rotating shafts 3 to rotate through multiple sets of sprockets 26 and chains 27, thereby rotating the four eccentric wheels 15, and then causing the four eccentric wheels 15 to squeeze the piston 14, thereby causing the piston 14 to slide inside the fixed box 2, and then when the piston 14 moves upward, the fixed column 23 moves upward, causing the fixed column 23 to slide inside the limiting plate 24, and causing the fixed column 23 to squeeze the return spring 25, thereby causing the gas inside the fixed box 2 to enter the inside of the air outlet pipe 5, causing the one-way valve 13 inside the air outlet pipe 5 to open, and the one-way valve 13 on the fixed box 2 to close, thereby causing the gas inside the fixed box 2 to be discharged through the air outlet pipe 5, and then causing the air outlet pipe 5 to blow air to the connection between the curtain wall outer frame 1 and the glass to prevent penetration.

[0046] Working principle:

[0047] Start the motor 28, so that the motor 28 drives one of the rotating shafts 3 to rotate, and then drives the four rotating shafts 3 to rotate through multiple sets of sprockets 26 and chains 27, thereby rotating the four eccentric wheels 15, and then the four eccentric wheels 15 squeeze the piston 14, and then the piston 14 slides inside the fixed box 2, and then when the piston 14 moves upward, the fixed column 23 moves upward, and the fixed column 23 slides inside the limiting plate 24, and the fixed column 23 squeezes the return spring 25, thereby forcing the gas inside the fixed box 2 into and out. The inside of the air pipe 5 opens the one-way valve 13 inside the air outlet pipe 5, and the one-way valve 13 on the fixed box 2 closes, so that the gas inside the fixed box 2 is discharged through the air outlet pipe 5, and the air outlet pipe 5 blows air to the connection between the curtain wall outer frame 1 and the glass, thereby quickly drying. When the eccentric wheel 15 no longer squeezes the piston 14, the piston 14 and the fixed column 23 are reset by the elastic force of the reset spring 25, and the piston 14 moves upward, thereby closing the one-way valve 13 inside the air outlet pipe 5, opening the one-way valve 13 on the fixed box 2, and injecting air into the interior of the fixed box 2.

[0048] When the piston 14 moves upward, the suspension rod 16 and the extrusion block 19 will move upward, so that the extrusion block 19 will no longer squeeze the extrusion plate 17, and the extrusion plate 17 will be reset by the elastic force of the elastic spring 20, so that the first cleaning guide rod 12 will move toward the inside of the fixed box 2. When the piston 14 is reset, the inclined surface of the bottom of the extrusion block 19 will squeeze the upper end of the extrusion plate 17, so that the extrusion plate 17 will slide toward the inside of the fixed outer rod 18, and then the elastic spring 20 will be squeezed, so that the first cleaning guide rod 12 will move toward the inside of the water inlet 6, so as to push out the impurities inside the water inlet 6. When the piston 14 moves up and down, the second cleaning guide rod 21 will follow the piston 14 to move up and down, so as to facilitate dredging the drain hole 22 through the second cleaning guide rod 21.
