Description
Technical Field
[0001] This utility model relates to the field of rainwater harvesting devices, and in particular to a rainwater harvesting device for the roof of a public building. Background Technology
[0002] Rainwater harvesting systems are resource recovery devices based on the principle of natural runoff, used for collecting, purifying, and storing rainwater from the roofs of public buildings, enabling the secondary use of rainwater resources (such as for greening irrigation and cleaning). Their working principle involves collecting rainwater into drainage channels through the roof drainage structure, then transporting it through pipes to a storage tank. Some systems are equipped with basic filtration components to remove large particles of debris to meet subsequent usage needs. Generally, the purification and transmission of rainwater is achieved through a combination of pipe components and filtration structures.
[0003] However, current rainwater harvesting devices for public building rooftops have significant shortcomings in terms of ease of maintenance: traditional devices mostly use long, integrated pipes made of opaque materials, making it impossible to visually observe the clogging status of internal filter components. Disassembly of the pipes is required to determine if cleaning is necessary, making the operation both blind and cumbersome. Furthermore, when maintenance personnel use high-pressure water guns to clean, they can usually only clean from the top of the pipe, making it difficult to precisely clean the clogged areas, resulting in poor cleaning effectiveness and low maintenance efficiency. Therefore, those skilled in the art have provided a rainwater harvesting device for public building rooftops to solve the problems mentioned in the background art. Utility Model Content

[0012] 1. This device features a sealed and stable drainage pipe connection structure. On one hand, it uses threaded sleeves to lock the first and second connecting rings, combined with the fit and seal of the elastic sealing strip and groove, achieving both the stability of the pipe connection and effectively preventing rainwater leakage through double sealing, ensuring the reliability of the device's operation. On the other hand, the visibility of the transparent drainage pipe allows for quick location of the pipe blockage, and the flushing pipe can then be used to flush the blockage area in a targeted manner. Combined with the threaded plug elastic rope anti-loss design and the anti-leakage function of the sealing ring at the connection, a closed-loop operation of "location / flushing / observation" is achieved, greatly improving the efficiency of blockage removal while avoiding water waste caused by blind flushing. It also takes into account installation stability, sealing performance, and ease of maintenance. 2. With a robust and sealed connection structure, the threaded sleeve can securely lock the No. 1 connecting ring and the No. 2 connecting ring when assembling the drainage pipe assembly. The elastic sealing strip on the No. 1 connecting ring fits snugly against the groove of the No. 2 connecting ring to ensure the stability of the pipe connection and effectively prevent rainwater leakage. At the same time, the threaded connection method facilitates disassembly and maintenance in the later stage, improving the practicality of the device. Attached Figure Description

[0015] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0016] Reference Figures 1-5 A rainwater collection device for the roof of a public building includes a drainage trough 1, a drainage pipe assembly 2 is fixedly connected to the lower left end face of the drainage trough 1, and a water storage tank 3 is fixedly connected to the tail end of the drainage pipe assembly 2. The drain pipe assembly 2 includes a conventional water pipe 21 and a transparent drain pipe 22; a first connecting ring 23 is fixedly connected to the outer end face of both the upper and lower sides of the transparent drain pipe 22, and the outer end face of the first connecting ring 23 is provided with external threads; a second connecting ring 24 is fixedly connected to the outer end face of the conventional water pipe 21 on the side close to the transparent drain pipe 22, and the second connecting ring 24 is provided with external threads corresponding to the first connecting ring 23; a threaded sleeve 25 is threadedly connected to the second connecting ring 24, and the first connecting ring 23 is fixedly connected to the second connecting ring 24 through the threaded sleeve 25; An elastic sealing strip 26 is fixedly connected to the first connecting ring 23, and a groove corresponding to the elastic sealing strip 26 is provided on the second connecting ring 24; a reinforcing ring 27 is fixedly connected to the outer end face of the transparent drain pipe 22, and a flushing pipe 28 is fixedly connected to the reinforcing ring 27; the tail end of the flushing pipe 28 penetrates the inner wall of the transparent drain pipe 22; a sealing ring is fixedly connected at the connection between the flushing pipe 28 and the transparent drain pipe 22; an internal thread is provided inside the flushing pipe 28, and a threaded plug 29 is connected to the flushing pipe 28 through the internal thread; an elastic rope is fixedly connected to the outer end face of the threaded plug 29, and the tail end of the elastic rope is fixedly connected to the upper end face of the first connecting ring 23.
[0017] Specifically, by setting a sealed and stable drain pipe connection structure, when assembling the drain pipe assembly 2, first align the No. 1 connecting ring 23 on both sides of the transparent drain pipe 22 with the No. 2 connecting ring 24 of the conventional water pipe 21, so that the elastic sealing strip 26 on the No. 1 connecting ring 23 fits into the groove of the No. 2 connecting ring 24. Then rotate the threaded sleeve 25, and use the corresponding external threads on the No. 1 connecting ring 23 and the No. 2 connecting ring 24 to make the threaded sleeve 25 firmly lock the two together. After being compressed, the elastic sealing strip 26 fills the gap at the connection, achieving a double sealing effect. In daily use, the transparency of the transparent drain pipe 22 allows for direct observation of the internal water flow. When it is found that the water flow is obstructed or impurities accumulate in a certain section of the pipe, the blockage can be quickly located, and then the corresponding blocked section can be unscrewed for flushing. The threaded plug 29 at the opening of pipe 28 (the threaded plug 29 is connected to the first connecting ring 23 via an elastic rope to prevent loss after disassembly) connects to the water source in flushing pipe 28. The water flows through the tail end of flushing pipe 28 and is precisely sprayed onto the blockage area to directionally flush the blockage impurities on the inner wall of the pipe and the surface of filter frame 5. The sealing ring at the connection between flushing pipe 28 and transparent drain pipe 22 can prevent water leakage. During the flushing process, the flushing effect can be observed in real time through transparent drain pipe 22 to ensure that the blockage is completely removed. After flushing, the threaded plug 29 is tightened in the reverse direction to seal flushing pipe 28. This structure not only ensures the stability and sealing of the pipe connection, but also greatly improves the blockage cleaning efficiency through the combination design of "visual positioning + precise flushing" and avoids the waste of water resources caused by blind flushing.
[0018] Furthermore, a boss is fixedly connected to the inner wall of the transparent drain pipe 22, and a filter frame 5 is snapped onto the transparent drain pipe 22 through the boss; a protective net 4 is fixedly connected to the upper end of the drain trough 1, and the protective net 4 is pointed; a groove corresponding to the conventional water pipe 21 is provided on the lower left end of the drain trough 1; the conventional water pipe 21 is fixedly connected to the wall through a locking buckle assembly.
[0019] Specifically, by setting up a graded anti-clogging and stable installation structure, when collecting rainwater, the pointed protective net 4 on the upper end of the drainage channel 1 can first intercept large debris such as leaves and branches. The pointed design allows rainwater to flow quickly and prevents debris from accumulating on the surface of the protective net 4, ensuring smooth drainage. The protrusion on the inner wall of the transparent drainage pipe 22 provides installation support for the filter frame 5. The filter frame 5 can be installed by aligning it with the protrusion and snapping it on, without the need for additional tools. The filter frame 5 can perform secondary filtration of rainwater to remove fine impurities, and the transparent drainage pipe 22 can observe the clogging status of the filter frame 5 in real time, which is convenient for timely replacement. The groove on the lower left side of the drainage channel 1 is compatible with the conventional water pipe 21 to ensure accurate pipe connection. The conventional water pipe 21 is fixed to the wall by locking fastener components, which can effectively resist the influence of outdoor wind and vibration, and prevent the pipe from loosening and shifting. This structure realizes graded filtration and anti-clogging of rainwater, simplifies the installation and replacement process of filter components, and enhances the overall installation stability of the device, making it suitable for outdoor use on the roof of public buildings.
[0020] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
