Description

Technical Field

[0001] This utility model belongs to the field of building waterproofing technology, specifically relating to a building waterproofing device. Background Technology

[0002] Existing prefabricated houses are a new type of environmentally friendly and economical prefabricated housing construction, using color steel plates as the frame, sandwich panels as the enclosure material, and standard modular series for spatial combination. The components are connected by bolts. In actual use, they can be easily and quickly assembled and disassembled, meeting the general standard requirements of temporary buildings.

[0003] Currently, researchers in related fields have been continuously making technological improvements to further enhance the adaptability of prefabricated houses to different environments. For example, patent application number 202320271125.2 discloses a method that "water droplets are guided by a deflector plate, cooled by an internal ventilation channel, prevented by a waterproof plate, and better dissipated by a heat dissipation plate to improve the waterproofing of the building. A stabilizing plate can better support the push rod motor to prevent it from shifting, and the output rod on the push rod motor drives the isolation plate to move up and down, which can better prevent rainwater from entering." However, based on practical experience, strong winds often accompany rainy days, and rainwater can still flow into the house through ventilation gaps. Therefore, how to achieve large-scale air exchange in a short time is the key problem that existing technologies need to solve. Summary of the Invention

[0028] The first protective sleeve plate 2 has clearance grooves on both sides. Movable plates 7 are hinged inside the clearance grooves. The movable plates 7 can cover and seal the corresponding through grooves 4 and annular grooves 5. Each of the two movable plates 7 includes a movable plate body 71, a movable shaft 72, and two torsion springs 73.

The movable shaft 72 is fixedly sleeved in the middle of one side of the corresponding movable plate body 71, and the two ends of the movable shaft 72 are respectively engaged in the two stepped holes in the corresponding clearance groove. One end of the two torsion springs 73 is fixedly connected to the surface of the two ends of the movable shaft 72, and the other end of the two torsion springs 73 is fixedly connected to the inner wall of the middle of the two clearance holes. The movable plates 7 have the function of flipping and resetting. The surfaces of the two movable plates 71 are nested with sealing rings, and the sealing rings can fill and seal the fitting gap between the movable plates 71 and the corresponding clearance grooves, thereby improving the sealing effect of the movable plates 71 in the clearance grooves.

[0029] Furthermore, a composite pneumatic assembly 6 is provided between the bottom of the movable plate 7 and the corresponding annular groove 5. Both composite pneumatic assemblies 6 include an annular airbag 61, a return spring 62, and a pressure sensor 63. The annular airbag 61 is fitted inside the corresponding annular groove 5, and the bottom surface of the annular airbag 61 is fixedly glued to the bottom inner wall of the corresponding annular groove 5. The return spring 62 and the pressure sensor 63 are both fitted inside the annular airbag 61. After the annular airbag 61 expands, it can guide the flipping thrust to the movable plate 71, thereby satisfying the effect of automated yielding operation.

[0030] An axial fan 8 and a conical duct 9 are installed inside the roof support 1. The output end of the axial fan 8 is installed inside the bottom of the conical duct 9. Both sides of the top of the conical duct 9 are fixedly connected to the guide branch pipes 10. One end of each of the two guide branch pipes 10 is fixedly connected to the diversion cone pipe 11. The diversion cone pipe 11 can be aligned with the corresponding through groove 4. One end of each of the two guide branch pipes 10 is connected to a multi-end fitting 12.

[0034] Working principle: Example 1

[0035] When the environment is sunny but the house needs ventilation, the solenoid valve of the first solenoid valve pipe 121 inside the multi-end fitting 12 and the axial fan 8 can be opened. The axial fan 8 accelerates and guides the air in the house to the interior of the two annular airbags 61 through the conical duct 9 and the two guide branches 10. Then, the two annular airbags 61 expand and deform and press against their respective movable plates 71. The movable plates 71 are then flipped and moved in the corresponding clearance groove under the support of the corresponding movable shaft 72 and torsion spring 73.

[0036] When the air pressure sensor 63 inside each of the two annular airbags 61 detects that the air pressure has reached the specified data, the axial fan 8 and the solenoid valve of the first solenoid valve tube 121 are closed. After completion, the two annular airbags 61 will remain in an inflated state. Similarly, the two movable plates 71 will also remain in a flipped and rearranged state. Subsequently, the air in the house will be exchanged with the air in the usage environment through the gap created by the two movable plates 71 and the two assembled waterproof plates 3, which are fitted one-to-one, to meet the ventilation requirements.

[0037] When the subsequent ventilation is completed and the two movable plates 71 need to be reset, the solenoid valves of the second solenoid valve pipes 122 inside the two multi-end pipe fittings 12 are opened. The air inside the two annular airbags 61 will be discharged through their respective second solenoid valve pipes 122, and then reset and retract. At the same time, the two movable plates 71 will also be flipped and reset by the reset spring force of their respective torsion springs 73, restoring the full waterproof effect of the first protective sleeve plate 2 and the two assembled waterproof plates 3. Example 2

[0038] When it rains in the environment but the house still needs ventilation, the solenoid valve of the first solenoid valve pipe 121 inside the multi-end fitting 12 and the axial fan 8 can be opened. The axial fan 8 accelerates and guides the air in the house to the inside of the two annular airbags 61 through the conical duct 9 and the two guide branches 10. Then, the two annular airbags 61 expand and deform and press against their respective movable plates 71. The movable plates 71 are then flipped and moved in the corresponding clearance groove under the support of the corresponding movable shaft 72 and torsion spring 73.

[0039] When the air pressure sensor 63 inside each of the two annular airbags 61 detects that the air pressure has reached the specified data, the solenoid valve of the first solenoid valve tube 121 is closed. After completion, the two annular airbags 61 will remain in an inflated state. Similarly, the two movable plates 71 will also remain in a flipped-over state. Then, the axial flow fan 8 will remain in an on state. The axial flow fan 8 will then actively and rapidly discharge the air in the house through the gap created by the two movable plates 71 and the two assembled waterproof plates 3, which correspond one-to-one. This will allow for a large amount of air exchange with the air in the environment in a short time, meeting the ventilation requirements. During the ventilation process, due to the continuous output of airflow, rainwater will have difficulty getting close, thus achieving a de facto waterproofing effect.

[0040] When the subsequent ventilation is completed and the two movable plates 71 need to be reset, the solenoid valves of the second solenoid valve pipes 122 inside the two multi-end pipe fittings 12 are opened. The air inside the two annular airbags 61 will be discharged through their respective second solenoid valve pipes 122, and then reset and retract. At the same time, the two movable plates 71 will also be flipped and reset by the reset spring force of their respective torsion springs 73, restoring the full waterproof effect of the first protective sleeve plate 2 and the two assembled waterproof plates 3.
