Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and more specifically, it relates to a roof drainage structure. Background Technology

[0002] The roof is the load-bearing and enclosing component at the top of a building. It generally consists of three parts: the roof surface, the insulation layer, and the load-bearing structure. The roof is also known as the "fifth facade" of a building, and it has a significant impact on the shape and facade of the building. The form of the roof will directly affect the overall image of the building. Roofs usually have a movable slope to facilitate roof drainage.

[0003] However, most existing roof drainage structures use conventional slopes to divert and discharge rainwater, and are equipped with filtration structures to remove impurities from the rainwater on the roof in order to avoid clogging of the drainage pipes and affecting the drainage effect. Although such roof drainage structures can meet normal drainage needs, in weather with heavy rainfall, the amount of filtration work of the filtration structure increases significantly, which also greatly increases the probability of clogging of the filtration structure. Once an accidental blockage occurs, the drainage structure will lose its drainage effect.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a roof drainage structure with the advantage of stable drainage.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a roof drainage structure, including a drainage ditch disposed on the side of the roof, a connecting plate disposed on the side of the drainage ditch near the roof, a slope provided on the connecting plate, the slope sloping towards the drainage ditch, a filter plate rotatably connected to the drainage ditch by a driving component, the side of the filter plate near the roof being connected to the drainage ditch via a rotating shaft, an arc surface for the filter plate to rotate provided on the side of the drainage ditch away from the roof, a drain outlet provided at the bottom of the drainage ditch, and a drain pipe connected to the drain outlet.

[0007] The present invention is further configured such that: two limiting plates are fixedly connected to the inner side of the drainage ditch, and the two limiting plates are respectively located on the upper and lower sides of the arc surface.

[0008] The present invention is further configured such that: an opening is provided below the connecting plate, and a collection trough is detachably connected to the side of the opening away from the filter plate.

[0009] The present invention is further configured such that: a filter sheet is detachably connected inside the collection tank, and a drain outlet is provided at the bottom of the collection tank, and the drain outlet is connected to the inside of the drainage ditch.

[0010] The present invention is further configured such that: a sealing plate is detachably connected to the opening, and a handle is fixedly connected to one side of the sealing plate.

[0011] The present invention is further configured such that: the driving component includes two mutually symmetrical motors, the output end of the motor is fixedly connected to the rotating shaft, the motor is covered with a cover, and the two motors start synchronously.

[0012] In summary, this utility model has the following beneficial effects:

[0013] When it rains, rainwater flows down the roof and into the drainage ditch via the slope on the connecting plate. The rainwater first flows through the filter plate, which allows rainwater to pass through but intercepts large debris such as leaves and branches to prevent them from entering the drainage ditch and thus preventing blockage of the drain outlet. When there are many impurities, the filter plate can be driven by the drive component to rotate around the rotating shaft and along the curved surface, allowing the impurities to slide along the slope of the filter plate, thus keeping the filter outlet on the surface of the filter plate clear.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] A roof drainage structure, such as Figures 1-4 As shown, the system includes a drainage ditch 1 located on the side of the roof. A connecting plate 2 is installed on the side of the drainage ditch 1 closest to the roof. A ramp 3 is formed on the connecting plate 2, sloping towards the drainage ditch 1. A filter plate 4 is rotatably connected to the drainage ditch 1 via a driving component. The side of the filter plate 4 closest to the roof is connected to the drainage ditch 1 via a rotating shaft. An arc surface 5 for the filter plate 4 to rotate is formed on the side of the drainage ditch 1 furthest from the roof. A drain outlet 6 is located at the bottom of the drainage ditch 1, and a drain pipe 7 is connected to the drain outlet 6. During rain, rainwater... Water flows down the roof and into the drainage ditch 1 via the slope 3 on the connecting plate 2. Rainwater first flows through the filter plate 4, which allows rainwater to pass through but intercepts large debris such as leaves and branches to prevent debris from entering the drainage ditch 1, thus preventing the drain outlet 6 from becoming blocked. When there are many impurities, the filter plate 4 can be driven by the drive component to rotate around the rotating axis and along the arc surface 5, so that the impurities can slide along the slope of the filter plate 4, thus making it easy for the filter outlet on the surface of the filter plate 4 to remain unobstructed.

[0023] In one embodiment, the driving component includes two symmetrical motors 15. The output end of the motor 15 is fixedly connected to the rotating shaft. A cover 16 is fitted on the outside of the motor 15. The two motors 15 start synchronously, which protects the motors 15. The two motors 15 start synchronously to drive the filter plate 4 to rotate, thereby improving the stability of the filter plate 4 during rotation.

[0024] Furthermore, two limiting plates 8 are fixedly connected to the inner side of the drainage ditch 1. The two limiting plates 8 are located on the upper and lower sides of the arc surface 5 respectively. Under the limiting action of the limiting plates 8, the filter plate 4 will not rotate excessively, ensuring that the filter plate 4 can always fit in contact with the inner wall of the drainage ditch 1, preventing impurities from directly entering the drainage ditch 1.

[0025] In one embodiment, an opening 9 is provided below the connecting plate 2. A collection tank 10 is detachably connected to the side of the opening 9 away from the filter plate 4. A filter sheet 11 is detachably connected inside the collection tank 10. A drain outlet 12 is provided at the bottom of the collection tank 10. The drain outlet 12 is connected to the inside of the drainage ditch 1. A sealing plate 13 is detachably connected to the opening 9. A handle 14 is fixedly connected to one side of the sealing plate 13. When the sealing plate 13 is removed, impurities that slide off the filter plate 4 can enter the collection tank 10 along the slope of the filter plate 4. The filter sheet 11 can filter these impurities. The rainwater carried by the impurities can enter the drainage ditch 1 from the drain outlet 12, thereby ensuring the dryness of the impurities and reducing the odor produced by the impurities. The presence of the filter sheet 11 can prevent impurities from entering the drain outlet 6 and causing the drain outlet 6 to become blocked, thus improving the sustainability of impurity filtration.

[0026] The method of using this utility model is as follows:

[0027] When it rains, rainwater flows down the roof and flows into the drainage ditch 1 via the slope 3 on the connecting plate 2. The rainwater first flows through the filter plate 4, which allows rainwater to pass through but intercepts large debris such as leaves and branches to prevent debris from entering the drainage ditch 1, thus preventing the drain outlet 6 from becoming blocked. When there are many impurities, two motors 15 can be started at the same time to make the filter plate 4 slide along the arc surface 5, so that the impurities enter the collection tank 10 from the opening 9, collect the impurities, prevent the filter plate 4 from becoming blocked, and ensure that the filter plate 4 can drain water stably.

[0028] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
