Description

Technical Field

[0001] The present invention relates to the technical field of landscape systems, and particularly to a rainwater collection and reuse display landscape system in an existing roof landscape. Background Art

[0002] China began to collect and utilize rainwater in the 1980s, starting relatively late compared with foreign countries, and the development of roof rainwater collection and utilization systems is relatively backward. In traditional building rainwater utilization, generally, the rainwater on the roof flows into the drainage ditch through the downspout and then into the rainwater pipeline. This way of rainwater treatment not only increases the burden on the rainwater pipeline but also wastes precious rainwater resources.

[0003] Therefore, we designed a rainwater collection and reuse display landscape system in an existing roof landscape. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems existing in the prior art, and to provide a rainwater collection and reuse display landscape system in an existing roof landscape.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A rainwater collection and reuse display landscape system in an existing roof landscape includes an existing roof with a building and eaves around it. A sloping roof is provided on the top of the building. An eaves gutter and a gutter are provided below the eaves, and the gutter is located below the eaves gutter. A landscape wall is partially provided on the inner side wall of the eaves. A rainwater collection landscape pool is provided below the landscape wall, and the landscape wall is located in the rainwater collection landscape pool. One part of the eaves gutter is communicated with the rainwater collection landscape pool.

[0007] Preferably, a water collection trough is provided at the edge of the sloping roof. A water collection trough is provided on the top of the landscape wall and part of the eaves, and the water outlet of the water collection trough is above the water inlet of the water collection trough. A drop trough is provided at the inner bottom of the rainwater collection landscape pool, and the drop trough is below the water outlet of the water collection trough.

[0008] Preferably, a rainwater diversion pipe is provided between the eaves gutter and the rainwater collection landscape pool, and both ends of the rainwater diversion pipe are communicated with the eaves gutter and the rainwater collection landscape pool respectively.

[0009] Preferably, a first float valve is provided at the end of the rainwater diversion pipe located in the rainwater collection landscape pool.

[0010] Preferably, a downspout is vertically provided in the eaves gutter. The lower end of the downspout penetrates through the inner bottom of the eaves gutter and extends into the gutter, and the top height of the downspout is higher than the inner bottom of the eaves gutter.

[0011] Preferably, an overflow pipe is fixedly connected to the top side wall of the rainwater collection landscape pool, and the overflow pipe penetrates the wall of the rainwater collection landscape pool and extends outward.

[0012] Preferably, a second float valve is provided at the end of the overflow pipe in the rainwater collection landscape pool.

[0013] Preferably, a drain pipe is provided on the rainwater collection landscape pool, and the drain pipe penetrates the wall of the rainwater collection landscape pool and extends outward.

[0014] Preferably, the drain pipe is located at the bottom of the inner wall of the rainwater collection landscape pool, and the bottom of the drain pipe is in contact with the inner bottom of the rainwater collection landscape pool.

[0015] Preferably, a blind pipe is provided in the rainwater collection landscape pool, and the blind pipe penetrates the wall of the rainwater collection landscape pool and extends outward, and expanded clay and permeable geotextile are provided at one end of the blind pipe close to the rainwater collection landscape pool.

[0016] The beneficial effects of the present invention are as follows:

[0017] In the existing roof landscape design, a water collection trough is set along the edge of the existing sloping roof to collect rainwater from the sloping roof. The rainwater in the trough is collected into the water collection trough in the form of a gravity water curtain and then flows into the rainwater collection landscape pool to form a waterfall landscape.

[0018] The top of the existing gutter rain pipe is transformed into a protruding gutter bottom, and a rainwater diversion pipe is added to the gutter to divert rainwater from the gutter into the rainwater collection landscape pool when it rains;

[0019] Blind pipes are set up in green belts and pavements, through which rainwater can be directed into rainwater collection landscape pools;

[0020] The rainwater collection landscape pool is equipped with an overflow pipe. When the pool is full, the rainwater overflows and flows into the gutter, and then drains into the existing rainwater drainage pipe for drainage;

[0021] Rainwater collection: Rainwater in the landscape pool can be led out through a water pump for greening irrigation, or it can be introduced into the water collection tank through a water pump to form a rainwater cycle and create a waterfall landscape.

[0022] To sum up, this device realizes the diversion of rainwater through the rainwater collection landscape pool, thereby reducing the burden on the existing rainwater pipes. Secondly, the rainwater collection landscape pool can collect rainwater to form landscape and external use effects, thereby making full use of rainwater. In addition, in the process of landscape design of the existing roof, the rainwater collection and utilization system is combined with landscape design techniques. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0027] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0028] Refer to Figure 1-2 , a rainwater collection and reuse display landscape system in an existing roof landscape, including an existing roof provided with a building and eaves 19 around, an existing sloping roof 1 is provided at the top of the building, an eaves gutter 12 and a gutter 13 are provided below the eaves 19, and the gutter 13 is located below the eaves gutter 12, wherein the gutter 13 is communicated with an existing rain drainage pipe, that is, the rainwater entering the gutter 13 flows into the existing rain drainage pipe;

[0029] Among them, a landscape wall 3 is partially provided on the inner side wall of the eaves 19, a rainwater collection landscape pool 8 is provided below the landscape wall 3, and the landscape wall 3 is located in the rainwater collection landscape pool 8, and a connection is provided between one place of the eaves gutter 12 and the rainwater collection landscape pool 8;

[0030] Furthermore, a rainwater diversion pipe 16 is provided between the eaves gutter 12 and the rainwater collection landscape pool 8, and both ends of the rainwater diversion pipe 16 are communicated with the eaves gutter 12 and the rainwater collection landscape pool 8 respectively. Through the setting of the rainwater diversion pipe 16, the rainwater in the eaves gutter 12 enters the rainwater collection landscape pool 8, thus achieving the technical effect of supplementing the rainwater in the rainwater collection landscape pool 8. And the use of the rainwater diversion pipe 16 is just one of the embodiments of the connection between the eaves gutter 12 and the rainwater collection landscape pool 8;

[0031] Furthermore, a first float valve 9 is provided at the end of the rainwater diversion pipe 16 located in the rainwater collection landscape pool 8. The first float valve 9 is a prior art and will not be elaborated here. Then, the opening and closing of the rainwater diversion pipe 16 are controlled by the first float valve 9. In this way, when the rainwater level in the rainwater collection landscape pool 8 is higher than the rainwater diversion pipe 16, the first float valve 9 closes, and the rainwater in the eaves gutter 12 enters the gutter 13 through the subsequent downspout 14.

[0032] It should be noted that: a water collection trough 2 is provided at the edge of the current sloping roof 1, and water collection troughs 4 are provided at the tops of the landscape wall 3 and part of the eaves 19. The water collection trough 4 on the landscape wall 3 and the water collection trough 4 on the eaves 19 can be communicated through a diversion port. In this way, rainwater flows from the current sloping roof 1 to the water collection trough 2, and then from the water collection trough 2 through the water collection trough 4 on the eaves 19 and the diversion port to the water collection trough 4 on the landscape wall 3 in sequence. And the water outlet of the water collection trough 2 is located above the water inlet of the water collection trough 4. A drop trough 7 is provided at the inner bottom of the rainwater collection landscape pool 8, and the drop trough 7 is located below the water outlet of the water collection trough 4. The rainwater falling on the current sloping roof 1 flows through the water collection trough 2, the water collection trough 4 and the drop trough 7 in sequence and falls into the rainwater collection landscape pool 8. In this way, the rainwater collection landscape pool 8 can achieve the technical effect of collecting the rainwater flowing down from the current sloping roof 1, and the rainwater creates a landscape after falling from the drop trough 7.

[0033] It should be noted that: a downspout 14 is vertically provided in the eaves gutter 12. The lower end of the downspout 14 penetrates the inner bottom of the eaves gutter 12 and extends into the gutter 13. The top height of the downspout 14 is higher than the inner bottom of the eaves gutter 12. Due to the height difference between the top of the downspout 14 and the eaves gutter 12, the rainwater in the eaves gutter 12 preferentially enters the rainwater collection landscape pool 8 through the rainwater diversion pipe 16. Furthermore, when the rainwater in the rainwater collection landscape pool 8 is higher than the height of the rainwater diversion pipe 16 and the first float valve 9 is closed, the rainwater in the eaves gutter 12 rises continuously and then flows to the water inlet at the top of the downspout 14, and then flows through the downspout 14 to the gutter 13 at the bottom and further to the rain drainage pipeline.

[0034] It should be noted that an overflow pipe 17 is fixedly connected to the top side wall of the rainwater collection landscape pool 8. The overflow pipe 17 penetrates through the pool wall of the rainwater collection landscape pool 8 and extends outward. Through the arrangement of the overflow pipe 17, it can be realized that the rainwater after the rainwater collection landscape pool 8 is filled flows into the gutter 13 and then flows to the rain drainage pipeline;

[0035] Furthermore, a second float valve 15 is arranged at the end of the overflow pipe 17 located in the rainwater collection landscape pool 8. The second float valve 15, like the first float valve 9, is an existing technology and plays a role in controlling the flow rate. That is, when the rainwater collection landscape pool 8 is about to overflow, the second float valve 15 opens, and the pool water in the rainwater collection landscape pool 8 is guided through the overflow pipe 17 to the gutter 13, thereby preventing the full pool water in the rainwater collection landscape pool 8 from falling onto the existing roof.

[0036] It should be noted that an emptying pipe 18 is arranged on the rainwater collection landscape pool 8. The emptying pipe 18 penetrates through the pool wall of the rainwater collection landscape pool 8 and extends outward. Through the arrangement of the emptying pipe 18, when the rainwater collection landscape pool 8 needs to be cleaned, the overall water volume in the rainwater collection landscape pool 8 can be controlled by opening and closing the control member on the emptying pipe 18. The control member can adopt components such as a sealing plug or a water valve, etc., thereby facilitating the cleaning effect of the rainwater collection landscape pool 8.

[0037] Furthermore, the emptying pipe 18 is located at the bottom of the inner side wall of the rainwater collection landscape pool 8, and the bottom of the emptying pipe 18 is in contact with the inner bottom of the rainwater collection landscape pool 8. With such a design, the pool water in the rainwater collection landscape pool 8 can all be drained into the gutter 13 through the emptying pipe 18 under the action of gravity.

[0038] It should be noted that a blind pipe 10 is arranged in the rainwater collection landscape pool 8, and the blind pipe 10 penetrates through the pool wall of the rainwater collection landscape pool 8 and extends outward. A ceramsite and permeable geotextile 11 is arranged at one end of the blind pipe 10 close to the rainwater collection landscape pool 8. The blind pipe 10 is arranged in the newly built green belt and pavement. In this way, the rainwater collected by the blind pipe 10 in the newly built green belt and pavement will also flow into the rainwater collection landscape pool 8, and the filtering effect of the rainwater of the blind pipe 10 is realized through the ceramsite and permeable geotextile 11.

[0039] Finally, a water pump 5 is arranged in the rainwater collection landscape pool 8, and the water outlet of the water pump 5 is connected with a delivery pipe. The water outlet of the delivery pipe is located in the water collecting trough 4. Through the arrangement of the water pump 5, when it does not rain, the water pump works to transport the rainwater in the rainwater collection landscape pool 8 to the water collecting trough 4, thus forming a water curtain landscape through the drop trough 7; a water press 6 is arranged in the rainwater collection landscape pool 8, and the water outlet of the water press 6 is connected with a connecting pipe. Through the arrangement of the water press 6, the rainwater in the rainwater collection landscape pool 8 can be led outwards, thereby realizing the irrigation of the greenery and the utilization of the rainwater.

[0040] As described above, it is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
