Description

Technical Field

[0001] This utility model belongs to the field of building drainage technology, and specifically relates to a drainage device for building energy conservation. Background Technology

[0002] In building construction, drainage systems are usually installed on the roof. These systems effectively prevent rainwater from seeping into the house, causing problems such as dampness and water leakage.

[0003] In the prior art, the roof is usually a sloping conical structure. The drainage device includes a U-shaped pipe, a drain pipe connected to the U-shaped pipe, and multiple filter screens arranged at intervals inside the U-shaped pipe. The U-shaped pipe is installed on the side of the roof. The slope of the roof allows rainwater to flow into the U-shaped pipe. Finally, the rainwater is guided by the U-shaped pipe and flows into the drain pipe to complete the treatment of rainwater. During the guidance process, the multiple filter screens inside the U-shaped pipe can filter out impurities mixed in the rainwater. These impurities are usually branches and leaves.

[0004] Although existing drainage devices can filter and treat rainwater, the sloping conical structure of the roof presents challenges. In heavy rain or strong winds, impurities mixed in with the rainwater can slip out of the U-shaped pipe due to the inertia of the slope, potentially falling outside and posing a safety hazard to pedestrians. Furthermore, to ensure effective filtration, the U-shaped pipe requires regular cleaning. Since multiple filters are spaced apart, operators must move frequently along the filter arrangement to clean each screen, making the process cumbersome. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a building energy-saving drainage device to solve at least one of the technical problems in the background art.

[0006] This utility model proposes a building energy-saving drainage device, which is applied to a sloping roof. The roof is equipped with a U-shaped pipe. The drainage device includes an irregularly shaped blocking component, a transmission pipe for installation on the roof, and a solid-liquid separation component. The two ends of the transmission pipe are respectively connected to the U-shaped pipe and the solid-liquid separation component, so that the solid-liquid mixture located in the U-shaped pipe is transmitted through the U-shaped pipe and the transmission pipe and then input into the solid-liquid separation component for solid-liquid separation.

[0007] The U-shaped tube includes a first arc-shaped portion and a second arc-shaped portion. The irregularly shaped blocking member is used to connect with one of the first arc-shaped portion and the second arc-shaped portion and form a blocking area. The irregularly shaped blocking member has a gap with the other of the first arc-shaped portion and the second arc-shaped portion to form an opening area corresponding to the solid-liquid mixture.

[0008] Furthermore, the irregularly shaped blocking member is fixedly connected to the first arc-shaped portion and forms the blocking area on the first arc-shaped portion;

[0009] The irregularly shaped blocking member and the second arc-shaped portion are spaced apart to form the opening area corresponding to the solid-liquid mixture.

[0010] Furthermore, the area size of the blocking area is equal to the area size of the opening area.

[0011] Furthermore, the irregularly shaped blocking component is detachably connected to the first arc-shaped portion;

[0012] The irregularly shaped blocking member is provided with a snap-fit ​​notch corresponding to the first arc-shaped portion.

[0013] Furthermore, the size of the snap-fit ​​notch gradually changes outward from small to large, so that when the irregularly shaped blocking member is connected to the first arc-shaped part, a portion of the first arc-shaped part and a portion of the snap-fit ​​notch are interference-fitted.

[0014] Furthermore, the drainage device also includes at least one fixing member, which is screwed onto the irregularly shaped blocking member;

[0015] The fastener is positioned directly opposite the snap-fit ​​notch, and by rotating the fastener, a portion of the fastener is made to fit tightly against the outer side of the first arc-shaped portion.

[0016] Furthermore, the solid-liquid separation assembly includes a collection tank, a filter screen disposed inside the collection tank, and a drain pipe and a sewage pipe connected to the collection tank;

[0017] The drain pipe and the sewage pipe are respectively located on opposite sides of the collection bucket.

[0018] Furthermore, the filter screen is inclined and arranged inside the collection bucket;

[0019] The drain pipe is directly opposite the filter screen, and the relative height of the drain pipe inlet is higher than the relative height of the drain pipe inlet.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] This utility model provides a drainage device for building energy conservation, including a shaped blocking member. The U-shaped pipe includes a first arc-shaped portion and a second arc-shaped portion. The shaped blocking member is used to connect with one of the first and second arc-shaped portions to form a blocking area. A gap exists between the shaped blocking member and the other of the first and second arc-shaped portions to form an opening area corresponding to the solid-liquid mixture. Utilizing a sloping roof, the solid-liquid mixture (rainwater and impurities) can slide along the slope of the roof. When the solid-liquid mixture slides to the opening area, it will pass through the opening area and fall into the U-shaped pipe. Inside, due to the influence of the external environment, such as heavy rain or strong winds, the solid-liquid mixture is easily affected by the external environment and generates a certain inertia. That is, the solid-liquid mixture will slide along the inner wall of the U-shaped tube. By setting the irregularly shaped blocking component, after sliding along the inner wall of the U-shaped tube, the solid-liquid mixture will adhere to the inner wall of the irregularly shaped blocking component and slide. Finally, under the influence of gravity, the solid-liquid mixture will fall back into the U-shaped tube for transmission. This prevents the solid-liquid mixture with inertia from leaving the transmission range of the U-shaped tube and solves the problem in the existing technology that a small amount of impurities can easily slide out of the U-shaped tube and cause impurities to hit pedestrians.

[0035] Please see Figure 9 As shown, the U-shaped pipe 200 in the prior art, in environments such as heavy rain or strong winds, impurities mixed in with rainwater, due to the influence of the slope, will generate a certain inertia as they flow into the U-shaped pipe 200. This can cause a small amount of impurities to easily slide out of the U-shaped pipe 200 and fall outside, posing a safety hazard to pedestrians. It should be noted that... Figure 9 The arrows and line segments shown represent the movement trajectories of impurities and rainwater sliding out of the U-shaped tube 200.

[0036] First Embodiment

[0037] Please see Figures 1 to 6The image shows a building energy-saving drainage device provided in the first embodiment of this utility model. The drainage device 300 is applied to a roof 100 with a slope. A U-shaped pipe 200 is provided on the roof 100. In this example, the drainage device 300 includes an irregularly shaped blocking member 310, a transmission pipe 320 for being installed on the roof 100, and a solid-liquid separation component 330. The two ends of the transmission pipe 320 are respectively connected to the U-shaped pipe 200 and the solid-liquid separation component 330, so that the solid-liquid mixture located in the U-shaped pipe 200 is transmitted through the U-shaped pipe 200 and the transmission pipe 320 and then input into the solid-liquid separation component 330 for solid-liquid separation. It should be noted that the solid-liquid mixture is rainwater and impurities such as leaves and branches mixed in the rainwater.

[0038] The U-shaped tube 200 includes a first arc-shaped portion 210 and a second arc-shaped portion 220. The irregularly shaped blocking member 310 is used to connect with one of the first arc-shaped portion 210 and the second arc-shaped portion 220 and form a blocking area 230. The irregularly shaped blocking member 310 has a gap with the other of the first arc-shaped portion 210 and the second arc-shaped portion 220 to form an opening area 240 corresponding to the solid-liquid mixture.

[0039] In practical implementation, the sloping roof 100 allows the solid-liquid mixture (rainwater and impurities) to slide along the sloping surface of the roof 100. When the solid-liquid mixture slides to the opening area 240, it will pass through the opening area 240 and fall into the U-shaped tube 200. Due to the influence of the external environment, such as heavy rain or strong winds, the solid-liquid mixture is easily affected by the external environment and generates a certain inertia. That is, the solid-liquid mixture will slide along the inner wall of the U-shaped tube 200. Through the setting of the irregularly shaped blocking member 310, the solid-liquid mixture will slide against the inner wall of the irregularly shaped blocking member 310 after sliding along the inner wall of the U-shaped tube 200. Finally, due to the influence of gravity, the solid-liquid mixture will fall back into the U-shaped tube 200 for transmission, thereby preventing the solid-liquid mixture with inertia from leaving the transmission range of the U-shaped tube 200. This solves the problem in the prior art that a small amount of impurities can easily slide out of the U-shaped tube 200 and cause impurities to hit pedestrians.

[0040] For a further understanding of this case, please refer to Figure 6 As shown, Figure 6 The middle arrow and line segment represent the trajectory of the solid-liquid mixture along the inner wall of the U-tube 200 and the inner wall of the irregularly shaped blocking component 310.

[0041] Specifically, in some preferred embodiments, the irregularly shaped blocking member 310 is fixedly connected to the first arc-shaped portion 210 and forms a blocking area 230 on the first arc-shaped portion 210. There is a gap between the irregularly shaped blocking member 310 and the second arc-shaped portion 220 to form an opening area 240 corresponding to the solid-liquid mixture. The fixed connection can be that the irregularly shaped blocking member 310 and the first arc-shaped portion 210 are integrally formed. The fixed connection can effectively ensure the rigidity between the irregularly shaped blocking member 310 and the first arc-shaped portion 210.

[0042] It should be noted that the irregularly shaped blocking component 310 can adopt an arc-shaped structure that fits against the inner wall of the U-shaped tube 200, and the area size of the blocking area 230 is equal to the area size of the opening area 240. Please refer to [link / reference]. Figure 5 As shown, the U-shaped tube 200 and the irregularly shaped blocking member 310 can be understood as an annular structure with an opening. The area corresponding to the U-shaped tube 200 occupies 2 / 4 of the annular structure, the blocking area 230 occupies 1 / 4 of the annular structure, and the opening area 240 occupies 1 / 4 of the annular structure. By limiting the area size of the blocking area 230 and the opening area 240, the solid-liquid mixture has sufficient sliding space and sliding distance, and can effectively ensure that the solid-liquid mixture always falls into the U-shaped tube 200.

[0043] After the solid-liquid mixture is transported through the U-shaped pipe 200 and the transmission pipe 320, it will be transported to the solid-liquid separation component 330, which can be used to centrally separate rainwater and impurities in the solid-liquid mixture.

[0044] Specifically, the solid-liquid separation component 330 includes a collection tank 331, a filter screen 332 disposed in the collection tank 331, and a drain pipe 333 and a sewage pipe 334 connected to the collection tank 331, wherein the drain pipe 333 and the sewage pipe 334 are respectively disposed on opposite sides of the collection tank 331.

[0045] In practice, the solid-liquid mixture falls into the collection bucket 331. The rainwater and impurities in the solid-liquid mixture can be separated by the filter screen 332, so that the impurities can be filtered above the filter screen 332, while the rainwater is filtered at the bottom of the collection bucket 331. Finally, the rainwater and impurities can be transported to the outside of the collection bucket 331 by the drain pipe 333 and the sewage pipe 334.

[0046] To facilitate the handling of impurities, in some preferred embodiments, the filter screen 332 is inclinedly arranged inside the collection bucket 331, with the drain pipe 334 directly opposite the filter screen 332. The relative height of the drain pipe inlet is higher than that of the drain pipe inlet. The inclined arrangement of the filter screen 332 allows impurities to move along the inclined direction of the filter and be discharged by the drain pipe 334. Furthermore, the height difference between the drain pipe inlet and the drain pipe inlet prevents rainwater from falling into the drain pipe 334. This changes the arrangement of the filter screen 332 in the prior art and allows for the handling of impurities without the need for operator intervention, solving the problem of cumbersome operation when cleaning the filter screen 332 in the prior art.

[0047] It should be noted that the sewage pipe inlet is specifically the connection interface between the sewage pipe 334 and the collection bucket 331, and the liquid drain pipe inlet is specifically the connection interface between the liquid drain pipe 333 and the collection bucket 331.

[0048] In some alternative embodiments, the collection bucket 331 may consist of a bucket body and a closed door. In practice, it is difficult to avoid residual leaves adhering to the filter screen 332. To improve the filtration effect, the operator can open the collection bucket 331 to clean the residual leaves on the filter screen 332. It should be noted that the cleaning process only requires the operator to move once and only requires cleaning the residual leaves on the filter screen 332. The operation process is simple.

[0049] In summary, the building energy-saving drainage device provided in the first embodiment of this utility model has at least the following beneficial effects compared with drainage devices in the prior art:

[0050] This utility model provides a drainage device for building energy conservation, including a shaped blocking member 310. A U-shaped pipe 200 includes a first arc-shaped portion 210 and a second arc-shaped portion 220. The shaped blocking member 310 is used to connect with one of the first arc-shaped portion 210 and the second arc-shaped portion 220, forming a blocking area 230. A gap exists between the shaped blocking member 310 and the other of the first arc-shaped portion 210 and the second arc-shaped portion 220 to form an opening area 240 corresponding to the solid-liquid mixture. Utilizing a sloping roof 100, the solid-liquid mixture (rainwater and impurities) can slide along the slope of the roof 100. When the solid-liquid mixture slides to the opening area 240, it passes through... When the liquid falls into the U-shaped tube 200 from the opening 240, it is easily affected by the external environment, such as heavy rain or strong winds, and will generate a certain inertia. That is, the liquid mixture will slide along the inner wall of the U-shaped tube 200. With the setting of the irregularly shaped blocking member 310, the liquid mixture will slide along the inner wall of the U-shaped tube 200 and then slide against the inner wall of the irregularly shaped blocking member 310. Finally, under the influence of gravity, the liquid mixture will fall back into the U-shaped tube 200 for transmission, thereby preventing the liquid mixture with inertia from leaving the transmission range of the U-shaped tube 200. This solves the problem in the prior art that a small amount of impurities can easily slide out of the U-shaped tube 200 and cause impurities to hit pedestrians.

[0051] Second Embodiment

[0052] Please see Figures 7 to 8 The image shows a building energy-saving drainage device provided in the second embodiment of this utility model. The difference between this embodiment and the building energy-saving drainage device provided in the first embodiment is that:

[0053] The irregularly shaped blocking member 310 is detachably connected to the first arc-shaped part 210, wherein the irregularly shaped blocking member 310 is provided with a snap-fit ​​notch 311 corresponding to the first arc-shaped part 210.

[0054] Specifically, in some practical processes, especially in houses where U-shaped pipes 200 have already been installed, in order to prevent rainwater and debris from falling outside, in this embodiment, a snap-fit ​​notch 311 is provided on the irregularly shaped blocking member 310 so that the irregularly shaped blocking member 310 can be directly snapped onto the U-shaped pipe 200.

[0055] In some preferred embodiments, the size of the snap-fit ​​notch 311 gradually changes outward from small to large, so that when the irregularly shaped blocking member 310 is connected to the first arc-shaped part 210, a portion of the first arc-shaped part 210 is interference-fitted with a portion of the snap-fit ​​notch 311.

[0056] Furthermore, to further ensure the stability of the irregularly shaped blocking member 310 fixed to the first arc-shaped portion 210, the drainage device 300 also includes at least one fixing member 340, which is screwed onto the irregularly shaped blocking member 310. The fixing member 340 is directly opposite the snap-fit ​​notch. By rotating the fixing member 340, a portion of the fixing member 340 is tightly attached to the outer side of the first arc-shaped portion 210.

[0057] The example is not limited; fastener 340 can be made of bolts.

[0058] In summary, the energy-saving drainage device for buildings provided in the second embodiment of this utility model has at least the following beneficial effects compared to the energy-saving drainage device for buildings provided in the first embodiment:

[0059] When treating rainwater and debris in houses that have already been fitted with U-shaped pipes 200, the irregularly shaped blocking member 310 is detachably connected to the first arc-shaped part 210, so that the irregularly shaped blocking member 310 can be directly installed on the house that has already been fitted with U-shaped pipes 200, thereby preventing rainwater and debris from falling outside the house.
