Detailed Implementation

[0016] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0017] Reference Figure 1 and Figure 2As shown in the figure, this application discloses a roof drainage system with self-cleaning function, including: a gutter 2, installed on the wall 1 of a steel structure factory building, located on one side of the roof; a first filter plate 31, installed in the gutter 2, used to intercept debris; wherein, the first filter plate 31 divides the gutter 2 vertically along the direction of gravity into: a receiving groove 21 above the first filter plate 31 and an external discharge cavity 22 below the first filter plate 31; a plurality of filter holes, opened on the first filter plate 31, one end connected to the receiving groove 21 and the other end connected to the external discharge cavity 22; a first drain pipe 41, one end connected to the external discharge cavity 22 and the other end extending towards the ground; a self-cleaning component, used to transport debris in the receiving groove 21 along the length of the gutter 2; and a receiving box, installed on the wall 1, located at one end of the gutter 2, connected to the receiving groove 21, used to receive debris.

[0018] In practical use, rainwater washes away debris from the roof of the steel structure factory building and falls into the receiving trough 21. The filter holes separate the debris from the rainwater. The debris remains in the receiving trough 21, while the rainwater enters the external drainage chamber 22 through the filter holes and is discharged to the ground along the first drainage pipe 41. It is worth mentioning that the self-cleaning component is activated periodically, transporting the debris in the receiving trough 21 along the length of the gutter 2 and sending the debris in the receiving trough 21 to the receiving box.

[0019] Specifically, the self-cleaning component includes: a rotating shaft 51, parallel to the gutter 2, rotatably disposed within the gutter 2; an auger 52, disposed along a spiral path on the rotating shaft 51, used for hanging and transporting miscellaneous items; wherein, a receiving box is disposed on one side of the auger 52; and a drive motor 53, mounted on the wall 1, with the output shaft of the drive motor 53 and the rotating shaft 51 being connected in a transmission manner.

[0020] When the debris on the first filter plate 31 needs to be self-cleaned, the drive motor 53 starts, and the output shaft of the drive motor 53 drives the rotating shaft 51 to rotate, thereby driving the auger 52 to scrape and send the debris along the length of the gutter 2 until the debris is pushed into the receiving box, thus completing the self-cleaning of the first filter plate 31.

[0021] In this utility model, by setting a first filter plate 31, debris and rainwater can be separated, preventing debris from entering the first drain pipe 41 and preventing debris from clogging the first drain pipe 41, thus ensuring normal drainage. A self-cleaning component is also provided, which can periodically remove debris from the first filter plate 31, preventing debris from blocking the filter holes and ensuring normal filtration of the first filter plate 31.

[0022] In this embodiment, the side of the first filter plate 31 closest to the auger 52 is an arc surface, and the auger 52 is installed with a clearance fit to the arc surface; specifically, the installation gap between the outer edge of the auger 52 and the arc surface of the first filter plate 31 is 4-8mm, which can increase the self-cleaning area of ​​the auger 52 on the first filter plate 31 and ensure the efficiency of hanging and transporting debris.

[0023] It is worth mentioning that a waterproof cover needs to be installed on the wall 1 to cover the drive motor 53 to prevent rainwater from entering the drive motor 53; in addition, the drive motor 53 itself can also be a waterproof motor to further ensure that it can operate in rainy weather.

[0024] In this embodiment, one end of the rotating shaft 51 is connected to the output shaft of the drive motor 53 via a coupling, and the other end of the rotating shaft 51 is rotatably mounted on the gutter 2 via a bearing; of course, the coupling can also be placed inside a waterproof cover, and the bearing should also be waterproofed by a sealing ring / sealing cover.

[0025] In this embodiment, the receiving box includes a box body 61 and a cover plate 62. The cover plate 62 is detachably installed on the box body 61. The box body 61 is provided with a feeding hole 63. One end of the feeding hole 63 is connected to the receiving groove 21, and the other end of the feeding hole 63 is connected to the interior of the box body 61.

[0026] It is worth mentioning that the cover plate 62 can be detachably installed on the box 61 with screws, allowing staff to periodically open the box 61 to clean up debris inside.

[0027] In this embodiment, the system further includes: a second filter plate 32, disposed inside the housing 61, which divides the housing 61 vertically along the direction of gravity into: a debris chamber 64 above the second filter plate 32 and a drainage chamber 65 below the second filter plate 32; and a second drain pipe 42, one end of which is connected to the drainage chamber 65 and the other end of which extends toward the ground.

[0028] It is worth mentioning that filter holes for rainwater to pass through are also provided on the second filter plate 32.

[0029] In specific operation, the debris scraped by the auger 52 falls into the draining chamber 65 through the feeding hole 63. The debris remains above the second filter plate 32, and the rainwater in the debris falls into the draining chamber 65 through the second filter plate 32 and is discharged to the ground through the second drain pipe 42.

[0030] Preferably, the system further includes a bracket 7, which is bolted to the wall 1 to support the gutter 2 and provide support for the gutter 2.

[0031] It is worth mentioning that the gutter 2 can also be detachably installed on the bracket 7 and the wall 1 by bolts, which further improves the stability of the gutter 2 installation; similarly, the drive motor 53 can also be supported by the bracket 7.

[0032] It is understood that the first filter plate 31 can be welded into the gutter 2, and the second filter plate 32 can be welded into the housing 61. Those skilled in the art will understand that although preferred embodiments of the present invention have been described, those skilled in the art, once they understand the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.
