[0002] In today's society, with the acceleration of urbanization, a large number of impervious surfaces have led to a sharp increase in rainwater runoff. Traditional urban drainage systems often only focus on the rapid discharge of rainwater, but ignore the collection and reuse of rainwater, which not only increases the risk of urban waterlogging and flood disasters, but also causes a huge waste of precious water resources.

[0003] On the other hand, with the improvement of environmental protection awareness, people have begun to realize the importance of rainwater resources and seek effective rainwater collection and utilization systems. However, existing technologies often have some problems, such as low rainwater collection efficiency, difficult to ensure water quality, complex equipment and difficult maintenance. These problems limit the widespread application of rainwater collection systems.

[0004] In view of the above problems, the present invention proposes a rainwater treatment device for drainage. The development of an efficient, low-cost and easy-to-maintain rainwater treatment device is of great significance for alleviating urban water shortages and protecting urban water environments. This device should be able to fully treat rainwater before it enters the drainage system, remove suspended solids and harmful substances, reduce operating costs, and facilitate daily maintenance.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The utility model provides Figure 1 and Figure 2 The rainwater treatment device for drainage and waterproofing shown in the figure comprises a water pipe 1, a water collecting funnel 2 is arranged directly below the water pipe 1, the water pipe 1 introduces rainwater into the water collecting funnel 2, a filter cover 3 is arranged at the upper end of the water collecting funnel 2, and the filter cover 3 is located directly below the water pipe 1, the filter cover 3 filters impurities in the rainwater introduced by the water pipe 1, the lower end of the water collecting funnel 2 is connected with a connecting pipe 4 for connecting the water collecting funnel 2 with a sedimentation box 5, and the lower end of the connecting pipe 4 is connected with the sedimentation box 5 for sedimentation and To block the silt in the rainwater, the rear end of the sedimentation box 5 is connected to a water storage tank 6 for storing the collected rainwater. A water pump 7 is arranged inside the lower side of the rear end of the water storage tank 6 for extracting the collected rainwater. The upper end of the water pump 7 is connected to an outlet pipe 8 for draining the collected rainwater. A connector 9 is arranged at the center of the top of the filter cover 3. A plurality of impurity removal scrapers 10 are fixedly connected to the side wall of the connector 9. The connector 9 sweeps out the impurities blocked at the upper end of the filter cover 3 through the plurality of impurity removal scrapers 10 on the side wall.

[0026] Preferably, in the process of collecting rainwater, the water guide pipe 1 guides the rainwater into the upper end of the water collecting funnel 2, and filters the impurities in the rainwater through the filter cover 3 at the upper end of the water collecting funnel 2. At the same time, the filter cover 3 sweeps out the impurities blocked at the upper end through the top connector 9 and the impurity removal scraper 10 to prevent the filter cover 3 from being blocked. The water collecting funnel 2 guides the introduced rainwater into the sedimentation box 5 through the connecting pipe 4. The sedimentation box 5 blocks the lower side of the introduced rainwater, so that the heavier rainwater containing mud and sand is blocked and precipitated, and the cleaner rainwater will be introduced into the water storage tank 6. The rainwater inside the water storage tank 6 is then discharged through the water pump 7 and the outlet pipe 8 for secondary filtration and disinfection, and finally distributed for use.

[0027] like Figure 2 and Figure 3 As shown, a connecting shaft 11 is fixedly connected at the center of the lower end of the connecting head 9, which is used to connect the connecting head 9 and the turbine 13. The connecting shaft 11 is rotatably connected to the inside of the filter cover 3, and the lower end passes through the inside of the connecting pipe 4. The connecting shaft 11 is externally rotatably connected to a limit bearing 12 for fixing the position of the connecting shaft 11. The limit bearing 12 is fixedly connected to the inner wall of the connecting pipe 4 through a connecting rod. A turbine 13 is fixedly connected to the outer wall of the lower side of the connecting shaft 11, and the turbine 13 is located inside the connecting pipe 4 and on the lower side of the limit bearing 12. The turbine 13 provides power for the rotation of the connecting head 9 and the impurity removal scraper 10.

[0028] Preferably, during the process of the connector 9 and the scraper 10 cleaning the upper end of the filter cover 3, rainwater flows downward inside the connecting pipe 4, allowing the turbine 13 to rotate due to the flushing of rainwater, and driving the connector 9 and the scraper 10 to rotate through the connecting shaft 11 and the limit bearing 12, thereby providing cleaning power for the connector 9 and the scraper 10 without the need for additional power. The connector 9 and the scraper 10 clean the upper end of the filter cover 3, which can effectively avoid blockage of the upper end of the filter cover 3 and ensure that the rainwater introduced by the water pipe 1 can be completely collected by the water collecting funnel 2.

[0029] like Figure 4 and Figure 5 As shown, a plurality of limit bars 14 arranged laterally on the left and right are fixedly connected to the lower inner side of the sedimentation box 5, and the plurality of limit bars 14 are evenly distributed inside the sedimentation box 5, and are used to limit the swing position of the upper side of the mud guard 16. A plurality of mud guards 16 arranged laterally on the left and right are rotatably connected to the lower inner side of the sedimentation box 5 through a plurality of rotating shafts 15, and the plurality of rotating shafts 15 are respectively located in front of the plurality of limit bars 14, and are used to block rainwater containing mud and sand. The lower end of the sedimentation box 5 is connected to a mud storage box 17, and a sewage outlet is arranged at the center of the lower end of the mud storage box 17, and is used to collect and discharge mud and sand.

[0030] Preferably, after rainwater enters the sedimentation box 5, since the sedimentation box 5 is fan-shaped, the rainwater will slow down after entering the sedimentation box 5, and the water level will drop, making it easier for the heavier rainwater containing silt to sink. At this time, multiple mud guards 16 will block the sinking rainwater containing silt to settle inside the lower end of the sedimentation box 5, and the cleaner rainwater will flow from the upper side of the mud guard 16 into the water storage tank 6 for collection, and the mud guard 16 can adaptively adjust the vertical angle according to the speed of the water flow to increase the blocking height, that is, the faster the rainwater flow rate, the higher the blocking height of the mud guard 16, preventing the silt brought by the excessively fast water flow from flowing through the upper side of the mud guard 16, and since the rotating shafts 15 at both ends of the mud guard 16 are located just below the limit bar 14, the mud guard 16 will not be in a vertical state, so when the water flow rate is slow, it will rotate forward to reduce the blocking height.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
