[0019] Please see Figure 1-5 This utility model provides a technical solution: a rainwater collection device, including a rainwater collection tank 1, a sewage treatment tank 2, a rainwater channel 3, a sewage pump 4, a water guiding pipe 5, a water guiding trough 6, a filter screen 7, a check valve 8, a water inlet 9, a gate valve 10, an installation groove 11, a water outlet interface 12, a water outlet 13, an automatic float control mechanism 14, a threaded telescopic sleeve 15, a threaded connection groove 16, a threaded connection port 17, and a threaded telescopic connection pipe 18. The lower end of the rainwater collection tank 1 is connected to the rainwater channel 3, and the upper end of the rainwater collection tank 1 is covered and installed with the filter screen 7. The rainwater collection tank 1 has a two-stage sedimentation tank structure, and the rainwater collection tank 1 is connected to the rainwater channel 3 in an open-closed manner through the gate valve 10. This makes it convenient for the rainwater collection tank 1 to carry out sedimentation treatment, and it can treat sewage through the sedimentation of the gate valve 10.

[0020] The rainwater collection tank 1 is connected to the sewage treatment tank 2 via a sewage pump 4 and a water guide pipe 5 in a suction connection. The sewage pump 4 and the water guide pipe 5 are symmetrically distributed in two sets on the rainwater collection tank 1, which allows the sewage treatment tank 2 to further purify and treat rainwater, making recycling safer. The rainwater collection tank 1 is connected to the sewage treatment tank 2 in a one-way connection via the water guide pipe 5 and a check valve 8. The sewage pump 4 is connected to the rainwater collection tank 1 in an automatic suction connection via an automatic float control mechanism 14. This allows the water guide pipe 5 to prevent backflow through the check valve 8, avoiding waste. Furthermore, the sewage pump 4 can be automatically started and stopped by the automatic float control mechanism 14, improving automation.

[0021] A gate valve 10 is connected to the lower end of the rainwater collection tank 1 and is connected to the rainwater channel 3. A water guide channel 6 is installed on the upper edge of the rainwater collection tank 1, and an installation groove 11 is fixedly connected to the upper end of the inner wall of the rainwater collection tank 1. The water guide channel 6 is distributed in a funnel structure on the upper edge of the rainwater collection tank 1. The filter screen 7 is installed in a positioning splicing manner with the rainwater collection tank 1 through the installation groove 11. This allows the water guide channel 6 to easily introduce rainwater and to perform coarse filtration through the filter screen 7. Moreover, it is easy to disassemble and assemble, and facilitates cleaning of the inner wall of the sewage treatment tank 2.

[0022] The filter screen 7 is inserted into the mounting groove 11. The rainwater collection tank 1 has outlets 13 on both sides, and the inner wall of the outlet 13 is fitted with an outlet interface 12. One end of the outlet interface 12 is connected to the sewage pump 4, and the other end of the sewage pump 4 is connected to the water guide pipe 5. The sewage pump 4 is spliced ​​with the outlet 13 through the outlet interface 12. The water guide pipe 5 and the check valve 8 are rotatably spliced ​​with the sewage treatment tank 2 through the threaded connection groove 16 and the threaded connection port 17. The threaded connection port 17 is rotatably telescopically connected with the water guide pipe 5 through the threaded telescopic sleeve 15 and the threaded telescopic connection pipe 18. This makes it easy to independently disassemble and install the sewage pump 4 and facilitate maintenance.

[0023] A check valve 8 is installed in the middle of the water guide pipe 5, and a threaded telescopic sleeve 15 is installed at the other end of the water guide pipe 5.

An automatic float control mechanism 14 is integrated on the sewage pump 4, and the automatic float control mechanism 14 is inserted into the inner wall of the rainwater collection tank 1.

[0024] Working principle: When using this rainwater harvesting device, the device is first assembled and installed. When it rains, the rainwater flows into the rainwater collection tank 1 through the water guide channel 6 and is coarsely filtered through the filter screen 7 to collect the rainwater. The rainwater then settles in the rainwater collection tank 1. Next, the water level is detected by the automatic float control mechanism 14, and then the sewage pump 4 is automatically started to guide the rainwater into the sewage treatment tank 2 through the water guide pipe 5 for sewage treatment. Backflow can be prevented by the check valve 8. Then the rainwater is recycled. When it is necessary to treat the settled sewage, it can be discharged by opening the gate valve 10. When one set of sewage pumps 4 is damaged, another set can be used. It can be independently disassembled and installed through the water outlet 12, threaded connection groove 16, and threaded connection port 17 for maintenance and replacement. This is the usage process of this rainwater harvesting device.
