Description
Technical Field
[0001] This utility model belongs to the field of building drainage technology, and in particular relates to an energy-saving building drainage device. Background Technology
[0002] In the construction industry, drainage systems are an indispensable component of buildings. Their main function is to promptly remove rainwater and sewage from roofs and floors, ensuring the normal use and structural safety of the building. Traditional building drainage systems mostly only have a single drainage function, directly discharging rainwater and sewage into municipal drainage systems or sewers. However, with the increasing severity of water scarcity and the growing awareness of energy conservation and environmental protection, the limitations of these traditional drainage systems are becoming increasingly apparent.
[0003] Chinese utility model patent CN222500821U discloses an energy-saving building drainage device. A filter screen is installed at the upper end of the collection tank. The collection tank is rotatably connected to the first support plate via a rotating rod, and is limited by a torsion spring on its exterior. When it is necessary to remove fallen leaves from the top of the filter screen, the pull rope can be pulled to tilt the collection tank. The fallen leaves on the top of the filter screen fall off under the action of gravity. When the pull rope is released, the collection tank returns to horizontal under the action of the torsion spring. There is no need for people to climb up to clean it, which is safer and more convenient.
[0004] A search revealed that the existing technologies described above still have some defects and shortcomings in practical applications. The collection tank lacks a flow guiding function, making it prone to turbulence during rainwater flow and affecting its movement. Furthermore, the collection box of these devices is directly fixed to the building wall, placing an additional load on the wall, resulting in unstable installation, safety hazards, and poor filtration efficiency. Therefore, there is an urgent need to improve existing energy-efficient building drainage devices and provide a new energy-efficient building drainage system. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An energy-saving building drainage device includes drainage channels fixedly installed on the front and rear outer walls of the top of the building body. An intercepting net is welded and fixed to the inner side of the top of the drainage channel.

The diversion component includes:
[0030] The first connecting pipe 6 has a tee 7 fixedly installed at one end of the two first connecting pipes 6 that are close to each other, and the two first connecting pipes 6 that are far apart from each other are respectively fixedly connected to the left end of the two drainage troughs 2.
[0031] The drainage tube 8 is fixedly connected to the top of the tee 7. The drainage tube 8 includes a vertical section and a curved section located at the bottom of the vertical section. The bottom of the curved section is fixedly connected to a stainless steel corrugated pipe 9.
[0032] A water storage tank 10 is provided on the bottom left side of the main body 1. The water storage tank 10 is fixed on the ground and a water inlet pipe 13 is fixedly connected to its top. A filter cylinder 14 is installed between the water inlet pipe 13 and the metal corrugated pipe 9 through a sealing component. Multiple partition nets 18 are detachably installed inside the filter cylinder 14, and a storage chamber 19 is formed between two adjacent partition nets 18.
[0033] Based on the above structure, the top of the drainage trough 2 is inclined, and a guide plate 4 is fixedly provided at the bottom of the drainage trough 2. The upper surface of the guide plate 4 is inclined and is used to guide rainwater to the diversion component.
[0034] In this embodiment, the top of the drainage trough 2 is inclined and is fixedly equipped with an intercepting net 3, which can intercept impurities such as gravel and leaves to prevent them from entering the drainage trough 2 and causing blockage. Moreover, the guide plate 4 facilitates the guidance of rainwater towards the diversion component.
[0035] Based on the above structure, multiple guide ribs 5 are fixedly provided at equal intervals along the width direction on the upper surface of the guide plate 4 to guide the water flow, reduce the turbulence of the water flow in the tank, and improve the drainage efficiency.
[0036] In this embodiment, the multiple guide ribs 5 can reduce water flow turbulence and effectively improve drainage efficiency.
[0037] Based on the above structure, the vertical section and the curved section of the drainage pipe 8 are interconnected. The curved section is "S" shaped to reduce the water flow velocity and reduce the impact on the pipe.
[0038] In this embodiment, the lower half of the drainage pipe 8 is "S" shaped, which can reduce the water flow velocity, reduce the impact on the pipe, and prevent damage to the pipe.
[0039] Based on the above structure, a drain pipe 11 is fixedly connected to the bottom left side of the water storage tank 10, a valve 12 is installed on the drain pipe 11, and the outer wall of the water storage tank 10 is provided with an insulation layer made of rock wool.
[0040] In this embodiment, the installation of the drain pipe 11 and the valve 12 facilitates the release of rainwater from the water storage tank 10 for use, and the installation of the insulation layer can prevent the rainwater in the water storage tank 10 from freezing in a low-temperature environment.
[0041] Based on the above structure, the sealing assembly includes two first connecting discs 15 and two second connecting discs 16. The two first connecting discs 15 are respectively fixedly sleeved on the outer side of the metal corrugated pipe 9 and the water inlet pipe 13 at their closest ends. The two second connecting discs 16 are respectively fixedly sleeved on the outer side of both ends of the filter cylinder 14. Adjacent first connecting discs 15 and second connecting discs 16 are fixed by bolts and a sealing gasket 17 is provided between them. The sealing gasket 17 is made of waterproof rubber.
[0042] In this embodiment, a sealing assembly is used to facilitate the sealed connection between the metal bellows 9 and the water inlet pipe 13 and the filter cylinder 14, thus preventing rainwater leakage.
[0043] Based on the above structure, multiple storage chambers 19 are filled with gravel, ceramsite and activated carbon from top to bottom for filtering and purifying rainwater.
[0044] In this embodiment, by using the gravel, ceramsite and activated carbon respectively filled in the multiple storage chambers 19 inside the filter cylinder 14, the rainwater entering the water storage tank 10 can be filtered in multiple layers, and the filtration effect is better.
[0045] The working principle of this utility model is as follows:
[0046] When rainwater falls on the roof of the house body 1, it can flow down the sloping roof into the drainage channel 2. During the process of rainwater entering the drainage channel 2, the sloping top of the drainage channel 2 and the interception net 3 can intercept and guide debris such as gravel and leaves to the ground. The sloping upper surface of the guide plate 4 can guide the rainwater towards the diversion component. Moreover, the multiple guide ribs 5 on the upper surface of the guide plate 4 can guide the water flow and reduce turbulence, effectively improving drainage efficiency.
[0047] Rainwater can enter the filter cylinder 14 through the first connecting pipe 6, tee 7, drain pipe 8, and metal corrugated pipe 9. The lower half of the drain pipe 8 is "S" shaped, which can reduce the water flow velocity and reduce the impact on the pipe. The multiple storage chambers 19 in the filter cylinder 14 are filled with gravel, ceramsite, and activated carbon, respectively, which can achieve multi-layer filtration of rainwater entering the water storage tank 10, resulting in better filtration. The metal corrugated pipe 9 facilitates height compensation of the upper first connecting plate 15, which is conducive to stable connection between adjacent first connecting plates 15 and second connecting plates 16. At the same time, with the cooperation of the sealing gasket 17, efficient sealing is achieved, which can prevent rainwater from leaking from the connection. In addition, multiple partition nets 18 are detachably installed in the filter cylinder 14, which facilitates the replacement of filter materials and cleaning of impurities.
[0048] When the collected rainwater is needed, valve 12 is opened to release the rainwater from the storage tank 10 through drain pipe 11.
[0049] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model.
