Description

Technical Field

[0001] The present application relates to the technical field of rainwater filtration equipment, and in particular to a novel drainage protection device for rainwater outlets on building roofs. Background Art

[0002] Roof drainage protection primarily blocks and removes obstacles such as leaves and trash on the roof that could clog the roof's rainwater outlets. Due to drainage requirements, rainwater outlets are often located at lower roof elevations, allowing rainwater that falls on the roof to flow along the roof and drain into the lowered outlets. To increase drainage capacity, these outlets are typically left open. This is particularly true during the rainy season, when water volumes are high, making them prone to blockage by flushing debris.

[0003] The current measures mainly use wire mesh to filter obstacles, but after long-term use, the obstacles will cover the entire wire mesh, which will still prevent rainwater from passing through the wire mesh and cannot achieve long-term protection effects.

[0004] Therefore, it is necessary to propose a new technical solution to solve the above problems. Utility Model Content

[0005] In order to automatically block obstacles from entering the rainwater outlet when the amount of rainwater drainage is large and achieve a long-term protection effect, the present application provides a new drainage protection device for the rainwater outlet on the roof of a building.

[0006] This application provides a new type of drainage protection device for building roof rainwater inlets, which adopts the following technical solutions:

[0007] The chute is secured to a position adjacent to the drainpipe and is adapted to engage the drainpipe for disengaging the drain from the drain.

[0008] By adopting the above technical solution, when rainwater moves towards the obstacle removal mechanism, the flowing rainwater contacts the guide slope, thereby driving the obstacle removal plate to rotate, and the rainwater enters the drainage hole through the water filter net and flows into the rainwater outlet, while the obstacle is filtered by the water filter net and when the water filter net rotates, the obstacle is separated from the water filter net due to the action of centrifugal force.

[0009] Optionally, the guide slope is arranged in an arc shape, the center of the arc of the guide slope is arranged between adjacent obstacle removal wheels, and the end of the guide slope close to the rotating part is tangent to the water filter net.

[0010] By adopting the above technical solution, when rainwater exerts force on the guide slope to drive the obstacle removal structure to rotate, the rainwater can also move along the arc of the guide slope toward the water filter net, so that the rainwater can pass through the water filter net and flow into the drainage hole.

[0011] Optionally, a plurality of supporting feet are provided at the lower end of the mounting support, and the supporting feet abut against the roof where the rainwater outlet is located.

[0012] By adopting the above technical solution, the mounting bracket is supported by the supporting legs, so that the mounting bracket can be stably placed on the roof where the drain outlet is located.

[0013] Optional: The support legs are higher than or smaller than the size of the main obstacle.

[0014] By adopting the above technical solution, a small amount of rainwater flowing along the roof can flow into the rainwater outlet along the gap between the installation support and the roof, while the main obstacles to the flow of a small amount of rainwater will be blocked by the installation support and will not flow into the rainwater outlet.

[0015] Optionally: A tubular steel mesh is further provided at the lower end of the mounting support, and the steel mesh is inserted into the rainwater outlet and fits against the inner wall of the rainwater outlet.

[0016] By adopting the above technical solution, the wire mesh is used to block obstacles flowing along the gap between the installation support and the roof, making it difficult for the obstacles to enter the rainwater outlet. At the same time, the wire mesh inserted into the rainwater outlet can also limit the position of the device itself, so that the device can be stably set at the rainwater outlet to block obstacles.

[0017] Optional: The rotating part is rotatably connected to the mounting support through a connecting assembly, and the connecting assembly includes a fastening bolt, a plurality of gaskets sleeved on the fastening bolt and a fastening nut threadedly connected to the fastening bolt, the gaskets are respectively arranged above the rotating part and below the mounting support, the fastening bolt passes through the rotating part and the mounting support and is connected to the fastening nut, and the gasket is arranged between the fastening bolt and the fastening nut.

[0018] By adopting the above technical solution, the obstacle removal structure is connected to the mounting support by tightening the nut and the bolt, so that the obstacle removal structure can rotate stably on the mounting support, and the obstacle removal structure can be easily replaced after it is damaged.

[0019] Optionally, the fastening bolt outer sleeve is provided with an oil-free bearing, and the outer wall of the oil-free bearing is interference fit with the rotating part.

[0020] By adopting the above technical solution, the oil-free bearing is used to reduce the resistance of the obstacle removal structure to rotation, so that the obstacle removal structure can rotate smoothly and stably.

[0021] Optionally, the rotating part, the obstacle-clearing wheel, the obstacle-clearing sheet and the water filter net are integrally formed.

[0022] By adopting the above technical solution, the obstacle clearing structure is combined into a whole, which is not easy to fall apart when moving. At the same time, when it is used for a long time and causes a long time of rotation, the obstacle clearing structure can still remain a stable whole and can rotate stably.

[0023] Optionally, the rotating part, obstacle removal wheel, obstacle removal sheet and water filter net are all made of plastic.

[0024] By adopting the above technical solution, the overall weight of the obstacle clearing structure is made lighter, thereby reducing the resistance encountered by the obstacle clearing structure during rotation, making the obstacle clearing structure easier to rotate.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. By providing an inclined guide surface, rainwater can drive the entire obstacle removal structure to rotate when it contacts the guide surface. When the obstacle removal structure rotates, rainwater can also flow along the guide surface toward the water filter net. The rainwater passes through the water filter net and the drainage holes and flows into the rainwater inlet. When the obstacle removal structure rotates, obstacles attached to the obstacle removal structure are separated from the obstacle removal structure by the centrifugal force.

[0027] 2. By arranging multiple supporting feet under the mounting support, the mounting support can be stably placed on the roof where the rainwater outlet is located, and at the same time will not hinder the flow of small flow of rainwater into the rainwater outlet.

[0032] The present application is further described in detail below with reference to the accompanying drawings.

[0033] This application discloses a new type of drainage protection device for rainwater outlets on building roofs, such as Figure 1 As shown, the device comprises a mounting bracket 1 disposed at the rainwater outlet and an obstacle removal structure 2 disposed on the mounting bracket 1 to prevent clogging of the rainwater outlet. The mounting bracket 1 is disc-shaped, with its upper projection area being larger than the upper opening area of the rainwater outlet. Several support legs 11 are welded circumferentially to the lower end of the mounting bracket 1. Both the mounting bracket 1 and the support legs 11 are made of stainless steel, with the lower end of the mounting bracket abutting the roof surface where the rainwater outlet is located. The height of the support legs 11 is less than that of the main obstruction, preventing the main obstruction from flowing into the rainwater outlet through the gap between the mounting bracket 1 and the roof. Instead, rainwater flows directly into the rainwater outlet through the gap between the mounting bracket 1 and the roof, ensuring smooth rainwater discharge while also preventing obstructions from clogging the rainwater outlet.

[0034] The obstacle removal structure 2 includes a rotating member 21 rotatably connected to the mounting support 1, a plurality of obstacle removal wheels 22 circumferentially arranged on the outer wall of the rotating member 21, a water filter 23 arranged between adjacent obstacle removal wheels 22, and a plurality of obstacle removal plates 24 for driving the obstacle removal wheels 22 to rotate. The rotating member 21, obstacle removal wheels 22, water filter 23 and obstacle removal plates 24 are all made of plastic. The rotating member 21 is arranged in a vertical cylindrical shape, and the axis of the rotating member 21 coincides with the axis of the mounting support 1. The obstacle removal wheel 22 is arranged in a vertical plate shape. One end of the obstacle removal wheel 22 is integrally formed with the outer wall of the rotating member 21, and the other end of the obstacle removal wheel 22 is close to the outer wall of the mounting support 1. A gap is left between adjacent obstacle removal wheels 22, and the lower end of the obstacle removal wheel 22 is slidably engaged with the upper end surface of the mounting support 1. The water filter net 23 is arranged in an arc shape, with the axis of the water filter net 23 coinciding with the axis of the rotating member 21. The water filter net 23 is arranged circumferentially along the axis of the rotating member 21. The water filter net 23 is also integrally formed with two adjacent obstacle removal wheels 22, thereby closing the gap between adjacent obstacle removal wheels 22. The lower end of the water filter net 23 slides with the upper end of the mounting support 1 to filter obstacles and prevent them from entering between adjacent obstacle removal wheels 22. The upper end surface of the mounting support 1 is circumferentially penetrated by a plurality of drainage holes 12. The drainage holes 12 are arranged on the side of the water filter net 23 near the rotating member 21, allowing rainwater to flow from the water filter net 23 into the space between adjacent obstacle removal wheels 22 and then into the rainwater outlet through the drainage holes 12 on the mounting support 1.

[0035] The obstacle removal piece 24 is integrally formed at the end of the obstacle removal wheel 22 that is away from the rotating member 21. This end of the obstacle removal piece 24 is located outside the mounting bracket 1. A guide slope 241 is provided on the end of the obstacle removal wheel 22 that faces the rotation direction of the rotating member 21. The guide slope 241 is arc-shaped, with the axis of the arc of the guide slope 241 being vertical, and the center of the arc of the guide slope 241 being located between adjacent obstacle removal wheels 22. The end of the guide slope 241 that is closer to the rotating member 21 is tangential to the water filter 23 and is integrally formed with the water filter 23. When rainwater flows toward the drain hole 12, it contacts the guide slope 241, driving the obstacle removal structure 2 to rotate along the axis of the rotating member 21. During this rotation, the centrifugal force prevents obstacles from adhering to the water filter 23, thereby preventing the water filter 23 from becoming clogged and allowing rainwater to flow normally into the rainwater outlet for discharge.

[0036] like Figure 2 and Figure 3As shown, the rotating member 21 is connected to the mounting support 1 via a connecting assembly 3. The connecting assembly 3 includes a fastening bolt 31, two washers 33 mounted on the fastening bolt 31, and a fastening nut 32 threadedly connected to the fastening bolt 31. The fastening bolt 31 extends from top to bottom through both the rotating member 21 and the mounting support 1. The fastening bolt 31 is positioned below the mounting support 1 and connected to the fastening bolt 31. The two washers 33 are positioned above the rotating member 21 and below the mounting support 1, respectively, thereby ensuring a stable connection between the rotating member 21 and the mounting support 1. An oil-free bearing 34 is also mounted on the fastening bolt 31. The oil-free bearing 34 is mounted within the rotating member 21. The upper end of the oil-free bearing 34 abuts the washers 33, and the lower end of the oil-free bearing 34 abuts the upper end of the mounting support 1. The oil-free bearing 34 facilitates smooth rotation of the rotating member 21.

[0037] A tubular steel mesh 13 is vertically mounted on the lower end of the mounting bracket 1. The upper end of the steel mesh 13 is welded to the mounting bracket 1, and the lower end of the steel mesh 13 is inserted into the rainwater outlet and abuts against the inner wall of the rainwater outlet. Drain holes 12 are located within the upper opening of the steel mesh 13, allowing rainwater entering the drain outlet to flow into the inner cavity of the steel mesh 13 and drain into the rainwater outlet. The steel mesh 13 also defines the position of the entire device relative to the rainwater outlet, allowing the entire device to stably remove obstacles at the rainwater outlet.

[0038] The working principle of this embodiment is as follows: when rainwater flows toward the rainwater outlet, the rainwater contacts the guide slope 241, thereby driving the obstacle removal plate 24 to rotate, causing the entire obstacle removal structure 2 to rotate along the axis of the rotating part 21. The obstacles are filtered by the water filter net 23 and attached to the side of the water filter net 23 away from the rotating part 21. The rainwater enters the rainwater outlet through the water filter net 23 and the drain outlet. The obstacles attached to the water filter net 23 are detached from the water filter net 23 under the action of centrifugal force, so that the obstacles no longer block the water filter net 23.

[0039] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
