Description

Technical Field

[0001] The utility model relates to the technical field of drainage facilities, and more specifically to a rainwater gutter and a building drainage structure. Background Art

[0002] With the rapid development of urban architecture, the diversity of architectural design has become increasingly prominent, including architectural designs without eaves structures, such as parapet floor buildings. These buildings bring certain challenges in drainage design. Traditional rainwater drainage pipe systems are often arranged vertically, and normally require additional eaves structures to be set up on the building floor to place the water collection outlet and connect the rainwater drainage pipes. However, for buildings without such eaves structures, traditional drainage solutions are not applicable because they cannot effectively organize the centralized discharge of rainwater, which can easily cause moisture and damage to the walls, thus affecting the service life of the building and the living comfort.

[0003] In addition, some existing side-discharge rainwater pipe systems have the following defects:

[0004] In the prior art, the rainwater downpipes arranged with side discharge are usually opened at the bottom of the vertical wall at the water collection point of the building floor as a drain outlet, and a rainwater gutter and rainwater downpipes are arranged below the outer wall of the drain outlet; the side discharge hole and the rainwater gutter in the prior art are not connected and closed, and there is no transition, and the water flows directly through the side discharge hole and impacts the rainwater gutter under the action of gravity, causing a large noise;

[0005] Moreover, in actual engineering applications, foreign objects on the floor (such as leaves, branches, etc.) will enter the rainwater downpipes under the action of water flow; if the existing technical solution is adopted, foreign objects are easily accumulated in the rainwater gutter. Since the rainwater gutter is installed on the outer wall and is located at a high position, daily cleaning and maintenance are inconvenient; when the rainwater downpipe is blocked, since the existing rainwater gutter is not designed with an overflow port on the outside, water will accumulate on the floor due to pipe blockage.

[0006] In order to solve the above problems, a new type of rain gutter and building drainage structure is needed that can adapt to buildings without eaves structures, while reducing drainage noise, facilitating cleaning and maintenance, and improving the living experience. Utility Model Content

[0045] Embodiment 1:

[0046] like Figure 1As shown, the utility model provides a technical solution:

[0047] A rain gutter comprises a bending portion 3, one end of the bending portion 3 is connected to a water collecting pipe, and the other end of the bending portion 3 is connected to a water outlet pipe;

[0048] The water collecting pipe is provided with a water collecting port 2 at one end away from the bending portion 3;

[0049] The end of the water outlet pipe away from the bent portion 3 is provided with a water outlet 6;

[0050] An overflow port 7 is provided on the side wall of the water outlet pipe, and an end cap 5 for opening and closing the overflow port 7 is rotatably mounted on the overflow port 7. The end cap 5 is configured to be able to rotate under the buoyancy of water to open the overflow port 7;

[0051] Specifically, when water flows over the end cover 5, since the end cover 5 floats on the water, the end cover 5 floats up along the rotation axis under the action of buoyancy, that is, the overflow port 7 is opened to discharge the water, effectively preventing water accumulation on the floor due to pipe blockage.

[0052] Embodiment 2:

[0053] Based on Example 1, Figure 1 and Figure 4-6 A rotating shaft 501 is fixedly installed on the side of the end cover 5, and a rotating shaft mounting hole 4 adapted to the rotating shaft 501 is fixedly installed on the overflow port 7. The rotating shaft 501 is rotatably installed in the rotating shaft mounting hole 4, and the rotating shaft 501 can realize the rotating opening and closing function of the end cover 5 on the rain gutter.

[0054] Furthermore, an L-shaped slot 502 is provided at the lower end of the end cover 5, and an L-shaped groove adapted to the L-shaped slot 502 is provided at the lower end of the overflow port 7. The L-shaped groove is used to cooperate with the L-shaped slot 502 to limit the end cover 5, so that the end cover 5 can only rotate toward the inside of the water outlet pipe under the buoyancy of water, that is, it is used to limit the end cover 5 from everting outward, and avoid the end cover 5 from opening under the impact of water flow.

[0055] Furthermore, the end cover 5 is configured to close the overflow port 7 under the action of gravity when not affected by the buoyancy of water, that is, under normal conditions, the end cover 5 is in a closed state under the action of gravity.

[0056] Furthermore, the end cap 5 is made of a low-density material (foamed PVC, HDPE, etc.), floats on water, and the end cap 5 is a hollow structure.

[0057] Embodiment 3:

[0058] Based on Example 1, Figure 1-3 The water collection port 2 is detachably provided with a filter screen 1, which solves the problem in the prior art that foreign matter is easily accumulated in the rainwater bucket and is inconvenient to clean;

[0059] The utility model is provided with a detachable filter screen 1 at the water collection port 2 of the rain gutter, which can filter most foreign matter on the floor which is easier to clean. When the rainwater pipe is blocked, the detachable filter screen structure makes cleaning and dredging more convenient and simple.

[0060] Furthermore, the water collecting pipe is arranged horizontally; the bending portion 3 is a 90° corner section, and adopts a rounded and smooth transition structure, which effectively reduces drainage noise and improves the living experience.

[0061] Furthermore, the filter screen 1 comprises a boss 101 and a filter fence 102, wherein the filter fence 102 is arranged in the middle of the filter screen 1, and the boss 101 is arranged on the periphery of the filter fence 102;

[0062] The water collection port 2 is provided with a groove 201 adapted to the boss 101 .

[0063] Further, the boss 101 is a conical boss, the groove 201 is a conical groove, and the boss 101 and the groove 201 are connected by interference fit;

[0064] That is to say, a number of conical bosses are evenly distributed around the periphery of the filter screen 1, and the water collection port 2 of the rain gutter is also provided with conical grooves corresponding thereto, and the conical bosses and the conical grooves are connected by interference fit, thereby realizing the installation and disassembly functions of the filter screen 1.

[0065] Embodiment 4:

[0066] Based on Example 1, Figure 1 , the height of the overflow port 7 is lower than the water collecting port 2; specifically, the setting height of the overflow port 7 needs to be 5-10 cm lower than the water collecting port 2 to achieve the discharge of accumulated water when the pipeline is blocked and to minimize product costs.

[0067] Furthermore, the diameter area of ​​the rain gutter is gradually decreasing from the end close to the water collection port 2 to the end close to the water outlet 6;

[0068] That is to say, the rain gutter adopts a smooth transition structure, transitioning from the water collection port 2 to the water outlet 6, and the diameter area is in a decreasing transition to ensure that the minimum flow capacity of the rain gutter depends on the water outlet 6, which is convenient for subsequent engineering calculations.

[0069] Embodiment 5:

[0070] like Figure 7 As shown, the utility model provides a technical solution:

[0071] A building drainage structure comprises a building body 8 and at least one of the aforementioned rainwater buckets;

[0072] The building body 8 includes a floor layer 801, a vertical wall 802 and a rainwater pipe 803;

[0073] An installation hole is provided at the intersection of the floor layer 801 and the vertical wall 802. One end of the rain gutter with a water outlet 6 passes through the installation hole and is connected to the rainwater downpipe 803. One end of the rain gutter with a water collection port 2 is arranged on the inner side of the vertical wall 802.

[0074] Furthermore, the size of the water outlet 6 of the rain gutter is a standard round tube / square tube size, so as to facilitate the adaptation and connection to the rainwater downpipe 803, so that the rainwater gutter can be directly connected to the rainwater downpipe 803 to form a closed whole.

[0075] Specifically, during the engineering installation, the water collection port 2 of the rain gutter is arranged at the junction of the floor and the inner side of the vertical wall 802, and the water outlet 6 of the rain gutter is vertically downward and connected with the rainwater downpipe 803 in a socket connection. A filter screen 1 is provided at the water collection port 2 of the rain gutter, and the rainwater gutter is also provided with an overflow port 7 that can be controlled to open and close by an end cover 5. In actual use, when the rainwater and sewage mixture flows into the water collection port 2, the filter screen 1 provided at the water collection port 2 will filter out most foreign matter to avoid subsequent clogging of the pipeline. The filtered rainwater is guided by the smooth transition bucket structure and quickly passes through the water outlet and enters the rainwater downpipe system. When the pipeline is blocked, the overflow port 7 will automatically open under the thrust of the water flow to avoid many problems caused by water accumulation on the floor due to pipeline blockage.

[0076] Obviously, the above embodiments of the utility model are only examples for clearly explaining the utility model, and are not intended to limit the implementation methods of the utility model. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to list all the implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection scope of the claims of the utility model.
