Description

Technical Field

[0001] The utility model relates to a waterproof device for the eaves of a building roof. Background Art

[0002] The eaves, also known as the roof eaves, is the junction between the roof and the exterior wall, and is also one of the key decorative parts of the building. The main function of the eaves is to facilitate the drainage of rainwater on the roof and protect the wall. When it rains, rainwater flows from top to bottom along the wall, which will cause erosion to the wall in the process, which will cause harm to the building in the long run.

[0003] Traditional eaves will have drain outlets for drainage, and filters will be installed to prevent garbage from clogging the drain outlets. However, drain outlets that are open for a long time are easily covered by debris such as branches, leaves, and garbage, resulting in rainwater being unable to drain smoothly, and the filters are easily clogged, making them inconvenient to clean.

When it rains, rainwater flows downward into the guide frame 1 under the action of gravity. The guide frame 1 limits the rainwater, and the rainwater flows down from both sides of the guide frame 1 to protect the wall, preventing the rainwater from flowing down along the wall and causing the wall to be eroded by the rainwater; when the rainwater is heavy, the motor 6 is started, the motor 6 rotates to drive the filter screen 5 to rotate, the second rotating shaft 7 of the filter screen 5 rotates to drive the rotating frame 8 to rotate, the rotating frame 8 rotates to push the contact frame 12 upward, the contact frame 12 moves upward to drive the rack 13 to move upward, and the rack 13 moves upward The gear 14 is driven to rotate, the torsion spring 15 is twisted, the gear 14 rotates to drive the first rotating shaft 2 to rotate, the first rotating shaft 2 rotates to drive the dust frame 3 to rotate, the dust frame 3 rotates and no longer covers the drain port 17 on the guide frame 1, that is, the drain port 17 is in an open state, so that rainwater can be discharged in time, the contact frame 12 moves upward to push the locking frame 9 in the direction away from the guide pipe 4, the reset spring 10 is stretched, the contact frame 12 continues to move upward and disengages from the locking frame 9, the reset spring 10 will rebound and drive the locking frame 9 to move toward the direction close to the guide pipe 4 to reset, and the locking frame 9 will jam the contact frame 12 , and then the rack 13, the gear 14, the first rotating shaft 2 and the dustproof frame 3 are stuck, the filter screen 5 can block the garbage entering the guide tube 4. After the filter screen 5 rotates 180 degrees, the side of the filter screen 5 blocking the garbage faces downward. Under the action of the water flow, the garbage on the filter screen 5 is washed down, which can facilitate the cleaning of the filter screen 5. When the rain stops, turn off the motor 6, and push the locking frame 9 in the direction away from the guide tube 4 by pushing the contact plate 16. The reset spring 10 is stretched, the locking frame 9 is disengaged from the contact frame 12, and the locking frame 9 no longer blocks the contact frame 12. The torsion spring 15 will rebound and drive the gear 14 to rotate in the opposite direction. The gear 14 rotates in the opposite direction to drive the first rotating shaft 2 to rotate in the opposite direction, and the first rotating shaft 2 rotates in the opposite direction to drive the dust frame 3 to rotate in the opposite direction, and the dust frame 3 rotates in the opposite direction to cover the drain port 17 on the guide frame 1. Through the above operation, it is convenient to cover the drain port 17 on the guide frame 1 when there is no rain, reduce the probability of garbage blocking the drain port 17 on the guide frame 1, and facilitate drainage of the drain port 17 on the guide frame 1.
