Description

Technical Field

[0001] This invention relates to the field of roof drainage technology, specifically a novel combined direct-discharge and side-discharge roof rainwater inlet. Background Technology

[0002] Roof direct drainage outlets are structures on building roofs used to directly discharge rainwater. They are usually connected to drainage pipes to quickly drain rainwater accumulated on the roof, preventing rainwater buildup from damaging the roof. Roof direct drainage outlets are of great significance for protecting the structural safety of buildings, preventing leaks, and keeping indoor areas dry. At the same time, they are also an important part of the urban drainage system, playing an important role in alleviating urban flooding and protecting the urban environment. With continuous technological innovation, system optimization, and the growing popularity of environmental protection and energy conservation concepts, the development prospects of roof direct drainage outlets will be even broader.

[0003] For example, Chinese Patent (Announcement No.: CN207419878U) discloses a roof rainwater inlet backflow prevention device, which solves the problem of unreasonable structural design of existing roof rainwater hoppers, resulting in easy leakage and damage to the waterproof layer. The device includes a rainwater pipe and a rainwater hopper. The lower end of the rainwater hopper has a downward-protruding annular groove on its upper surface. A drainage pipe, connected to and located below the lower end of the rainwater hopper, is located in the middle of the lower end face of the hopper. A connecting pipe, fixed to the lower end face of the rainwater hopper and located inside the annular groove, is located on the outside of the drainage pipe. The upper end of the rainwater pipe is inserted into the gap between the drainage pipe and the connecting pipe. Rubber water-stop rings are provided between the drainage pipe and the inner side of the rainwater pipe, between the upper end face of the rainwater pipe and the lower end face of the rainwater hopper, and between the outer side of the rainwater pipe and the connecting pipe. This utility model has a reasonable and reliable structural design, effectively blocking the path of roof water seepage, preventing leakage, and effectively ensuring the waterproof layer. It has the advantages of simple structure, convenient processing, and low cost.

[0004] However, this device is prone to clogging, resulting in poor drainage. This is because fallen leaves or other debris inevitably accumulate on the roof. If these items are not cleaned up in time during rain, they will drift with the water flow to the device, causing blockage and further affecting the drainage effect. Therefore, a combined direct and side-drainage roof rainwater outlet is proposed to solve the above problems. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a novel combined direct and side-drain roof rainwater inlet, which has advantages such as not being blocked and having good drainage effect, thus solving the problem of drainage devices being blocked by garbage and other debris, resulting in unsatisfactory drainage.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a novel combined direct-discharge and side-discharge roof rainwater outlet, comprising a roof structure layer, the top of which is provided with a protective layer to protect the roof from rainwater intrusion, a waterproof layer fixed on the top of the protective layer, a surface layer for people to walk on on the top of the waterproof layer, a drainage component to improve drainage effect on the inner side of the surface layer, and drainage holes opened on the roof structure layer;

[0007] The drainage assembly includes a horizontal drainage plate located between the surface layer and the waterproof layer. The top of the horizontal drainage plate is fixedly connected to a plurality of water pipes extending vertically upward to the upper surface of the surface layer. The top of the horizontal drainage plate and the inner side of the surface layer are abutted by a plurality of support rods. The top of the plurality of support rods is fixed with a filter plate. A vertical drainage part with the same central axis as the drainage hole is welded to the center of the filter plate.

[0008] Furthermore, the protective layer includes an insulation layer fixed to the top of the roof structure layer, a concrete pad layer located inside the insulation layer is fixed to the top of the roof structure layer, a clamping steel plate is fixed to the top of the concrete pad layer, and a sealant is applied between the clamping steel plate and the concrete pad layer.

[0009] Furthermore, the top surface of the concrete cushion layer slopes from the edge towards the center at a downward angle of - degrees. The clamping steel plate is in contact with the concrete cushion layer. The top surface of the insulation layer and the clamping steel plate are on the same plane. The waterproof layer is coated on the insulation layer and the clamping steel plate.

[0010] Furthermore, the clamping steel plate passes through the drainage hole, and the lower end of the clamping steel plate is fixedly connected to the house drainage pipe.

[0011] Furthermore, the surface layer includes a base concrete, and a wear-resistant surface layer is fixed on top of the base concrete.

[0012] Furthermore, the horizontal drainage plate is disc-shaped and hollow inside. The horizontal drainage plate is attached to the waterproof layer. Multiple water passage holes are opened on the outer side wall of the horizontal drainage plate, and the inner side wall of the horizontal drainage plate is missing.

[0013] Furthermore, the filter plate has multiple filter holes, and multiple water pipes have anti-clogging nets fixed inside them, with the top surface of the anti-clogging nets and the top of the water pipes located on the same plane.

[0014] Furthermore, the vertical drainage section includes a housing fixed to the filter plate. A rotating hole is provided at the top of the housing. A sealed bearing is fixed inside the rotating hole. A rotating rod is rotatably connected to the inside of the sealed bearing. A support frame is rotatably connected to the outer surface of the rotating rod and located in the inner cavity of the housing. A spiral water-passing rod is fixed to the outer surface of the rotating rod and located below the support frame. Four blades are fixed to the outer surface of the rotating rod. A blade is fixed to the outer surface of the rotating rod and located between the four blades and the housing.

[0015] Furthermore, the outer shell is generally mesh-like, the bottom of the outer shell is connected to the drain hole, and a spiral conveying blade is fixed on the outer side of the spiral water-passing rod near the lower end.

[0016] Furthermore, the support frame consists of a stabilizing bearing and two reinforcing rods. The opposite sides of the two reinforcing rods are fixed to the outer shell, and the two reinforcing rods are rotatably connected to the rotating rod through the stabilizing bearing.

[0017] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0018] This new type of roof rainwater inlet, combining direct and side drainage, works by using a drain pipe and a filter plate to discharge rainwater in real time after it starts to rain. Furthermore, when trash drifts to the device, the drain pipe's suction force traps the trash, allowing the water to drain through the vertical drainage section. This device, through the cooperation of the horizontal and vertical drainage sections, effectively prevents trash from clogging the structure, improving drainage efficiency and ensuring that rainwater is discharged promptly, thus preventing rainwater accumulation and effectively protecting the building.

Detailed Implementation

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figure 1 This embodiment of a novel combined direct-discharge and side-discharge roof rainwater outlet includes a roof structure layer 1, a protective layer 2 on the top of the roof structure layer 1 to protect the roof from rainwater intrusion, a waterproof layer 5 fixed on the top of the protective layer 2, a surface layer 3 on the top of the waterproof layer 5 for people to walk on, a drainage component 4 to improve drainage effect on the inner side of the surface layer 3, and drainage holes on the roof structure layer 1.

[0025] In addition, the protective layer 2 includes an insulation layer 202 fixed to the top of the roof structure layer 1. A concrete pad 201 located inside the insulation layer 202 is fixed to the top of the roof structure layer 1. A clamping steel plate 203 is fixed to the top of the concrete pad 201. A sealant 204 is applied between the clamping steel plate 203 and the concrete pad 201. The sealant 204 can prevent rainwater from seeping in through the gap between the insulation layer 202 and the concrete pad 201, effectively protecting the house. At the same time, the insulation layer 202 and the waterproof layer 5 work together to ensure the house is waterproof and insulated, further improving the living comfort of residents.

[0026] It is known that the top surface of the concrete pad 201 slopes from the edge to the center at a downward angle of 10-30 degrees. The clamping steel plate 203 is attached to the concrete pad 201. The top surface of the insulation layer 202 and the clamping steel plate 203 are on the same plane. The waterproof layer 5 is applied to the insulation layer 202 and the clamping steel plate 203. Setting the concrete pad 201 in an inclined shape helps drainage and also serves as a positioning function, helping the vertical drainage part 405 to connect with the drainage hole more quickly. The clamping steel plate 203 passes through the drainage hole, and the lower end of the clamping steel plate 203 is fixedly connected to the building's drainage pipe. The clamping steel plate 203 is waterproof. By fixing and connecting the clamping steel plate 203 to the building's drainage pipe, rainwater can be ensured to flow out smoothly and leakage can be prevented during the rainwater flow process.

[0027] It is known that the surface layer 3 includes a base concrete 301, and a wear-resistant surface layer 302 is fixed on the top of the base concrete 301. The wear-resistant surface layer 302 is a wear-resistant floor tile, which can ensure wear resistance while improving surface friction.

[0028] In this embodiment, the sealant 204, waterproof layer 5, and pressing steel plate 203 work together to provide sufficient protection for the house, keep the interior of the house dry, and at the same time, the insulation layer 202 ensures the living experience of the residents. Finally, the drainage component 4 drains the water in real time, further improving the service life of the house.

[0029] Please see Figures 2 to 3 To avoid clogging and improve drainage, the drainage component 4 in this embodiment includes a horizontal drainage plate 401 located between the surface layer 3 and the waterproof layer 5. The top of the horizontal drainage plate 401 is fixedly connected to a plurality of water pipes 402 extending vertically upward to the upper surface of the surface layer 3. The top of the horizontal drainage plate 401 and located inside the surface layer 3 are abutted by a plurality of support rods 404. The top of the plurality of support rods 404 is fixed with a filter plate 403. A vertical drainage part 405 with the same central axis as the drainage hole is welded at the center of the filter plate 403.

[0030] It should be further explained that the horizontal drainage board 401 is disc-shaped and hollow inside. The horizontal drainage board 401 is attached to the waterproof layer 5. Multiple water holes are opened on the outer side wall of the horizontal drainage board 401, while the inner side wall of the horizontal drainage board 401 is missing. The water holes can also smoothly drain the rainwater that has seeped into the base concrete 301, further improving the drainage effect of the device.

[0031] Furthermore, the filter plate 403 has multiple filter holes, and multiple water pipes 402 are fixed with anti-clogging nets. The top surface of the anti-clogging nets is on the same plane as the top of the water pipes 402. The filter holes can ensure that the water flows smoothly and avoids blocking the garbage. The vertical drainage part 405 is fixed to the filter plate 403 by welding, which can improve the stability of the vertical drainage part 405. The anti-clogging nets and the wear-resistant surface layer 302 are on the same horizontal plane, which can improve the overall surface flatness and ensure aesthetics. At the same time, the anti-clogging nets can prevent small garbage from entering the water pipes 402 and ensure the smooth operation of the water pipes 402.

[0032] Additionally, the vertical drainage section 405 includes a housing 4051 fixed to the filter plate 403. A rotating hole is provided at the top of the housing 4051, and a sealing bearing 4052 is fixed inside the rotating hole. A rotating rod 4053 is rotatably connected to the inner side of the sealing bearing 4052. The sealing bearing 4052 prevents water from entering its interior, thereby improving its service life. A support frame 4054 is rotatably connected to the outer surface of the rotating rod 4053 within the inner cavity of the housing 4051. A spiral water-passing rod 4055 is fixed to the outer surface of the rotating rod 4053 below the support frame 4054. Four blades 4056 are fixed to the outer surface of the rotating rod 4053. A blade 4057 is fixed between the blade 4056 and the outer casing 4051. During actual drainage, rainwater will spontaneously form a vortex during the drainage process. If there is wind at this time, the wind will cause the blade 4056 to rotate, which will further cause the spiral water-passing rod 4055 on the rotating rod 4053 to rotate. If the rotation direction of the spiral water-passing rod 4055 is opposite to the direction of the vortex spontaneously formed by the water flow, the drainage efficiency will be reduced. The spiral water-passing rod 4055 can be set at a relatively high position, which can effectively avoid the vortex spontaneously formed by the water flow and the rotation of the spiral water-passing rod 4055 from affecting each other. When the water vortex itself has a good drainage effect, the water vortex is dominant. When the water vortex has a poor drainage effect, the water level will gradually rise, and at this time the spiral water-passing rod 4055 is dominant.

[0033] It is known that the outer shell 4051 is generally mesh-like, and the bottom of the outer shell 4051 is connected to the drain hole. The spiral water-passing rod 4055 has a spiral conveying blade fixed on its outer side and near the lower end. The mesh outer shell 4051 can ensure that water from all places can be discharged at the fastest speed, thereby effectively improving the drainage effect.

[0034] It should be noted that the support frame 4054 consists of a stabilizing bearing and two reinforcing rods. The opposite sides of the two reinforcing rods are fixed to the outer shell 4051. The two reinforcing rods are rotatably connected to the rotating rod 4053 through the stabilizing bearing. The cooperation between the reinforcing rods and the stabilizing bearing ensures the smooth operation of the rotating rod 4053. At the same time, the cooperation with the sealing bearing 4052 can limit the rotation of the rotating rod 4053, further improving the stability of the rotating rod 4053.

[0035] In this embodiment, the drainage effect can be greatly improved by the cooperation of the filter plate 403 and the outer shell 4051. At the same time, the blade 4056 can also cause the spiral water passage rod 4055 to rotate in the wind, further improving the drainage effect.

[0036] Understandably, the protective layer 2 and the surface layer 3 can provide sufficient protection for the roof, and with the cooperation of the water pipe 402 and the vertical drainage section 405, they can effectively prevent blockage, thereby greatly improving the drainage effect.

[0037] The working principle of the above embodiments is as follows:

[0038] When it rains, rainwater flows through the drain pipe 402 into the horizontal drainage plate 401, and then is discharged into the drain hole. When there is garbage or leaves on the roof, they may gradually move to the drain pipe 402 with the rainwater. Due to the low pressure below the drain pipe 402, the drain pipe 402 has a certain suction effect, absorbing the garbage or leaves. At this time, the water flows through the outer casing 4051 into the drainage pipe. At the same time, when the wind blows, the wind will blow the blades 4056, which will cause the rotating rod 4053 to rotate, further driving the screw... The rotating water-passing rod 4055 agitates the rainwater, causing it to flow out faster and further improving the drainage effect of the device. When the rainfall intensifies, the debris originally absorbed by the drain pipe 402 will flow under the scouring of the rainwater and be absorbed by the vertical drainage section 405. At this time, the drain pipe 402 can start draining again. The device will not be completely blocked by debris, ensuring that rainwater is discharged smoothly during rain. The good drainage effect can prevent rainwater from accumulating and eroding the sill plate for a long time, thereby improving the life of the building.

[0039] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
