[0045] The working principle of the circulating roof greening water storage and drainage system is as follows:

[0046] When it rains, rainwater will enter the main frame 1 through the placement plate 4 on the breeding frame 3, and be guided by the main frame 1 to flow into the filter mechanism 9. The rainwater passing through the filter mechanism 9 is filtered at this time. The rainwater falls into the breeding frame 3 for the plants in the breeding frame 3 to absorb. Then, the excess rainwater flows into the main frame 1 through the placement plate 4, and is then guided by the main frame 1 to the filter mechanism 9. The excess rainwater is filtered by the filter mechanism 9, so that the rainwater flowing into the water storage tank 8 has no excess impurities, so that the waterway pipeline of the spraying mechanism 10 is not blocked when the spraying mechanism 10 sprays. The rainwater enters the mounting seat 12 from the main frame 1, and then passes through the filter screen 16 to filter the rainwater. In order to clean the impurities on the filter screen 16, the staff pulls out the sliding seat 13 from the mounting seat 12. In order to better operate the sliding seat 13, the handle 14 is fixedly installed on the sliding seat 13.

The cooperation of the filter mechanism 9 and the spraying mechanism 10 can filter and utilize the rainwater. When the plants in the breeding frame 3 need to be irrigated, the working motor 22 starts to work to drive the lead screw 23 to rotate, so that the sliding seat 24 moves along the guide rail 20. With the movement of the sliding seat 24, the conduit 25 fixedly connected with the sliding seat 24 moves together. The movement of the conduit 25 allows the nozzle 26 to pass above the breeding frame 3. The nozzle 26 can irrigate the plants in the breeding frame 3. With the movement of the sliding seat 24, the water pipe 28 cooperates with the conduit 25 to move together. With the movement of the water pipe 28, the sliding block 29 is extruded, so that the movement distance of the water pipe 28 can be increased. In order to increase the movement stability of the sliding block 29, the guide wheel 30 is rotatably connected to the sliding block 29, which can guide the water pipe 28. In order to increase the movement stability of the sliding block 29, the mounting column 31 is fixedly installed on one end of the sliding block 29, and the auxiliary spring 32 is sleeved on the mounting column 31, so that the sliding block 29 can be elastically reset when compressed by the water pipe 28.

In order to increase the connection stability of the guide plate 27 and the water pipe 28, the mounting frame 35 and the fixed pipe 36 are fixedly installed on the sliding seat 24.The fixed pipe 36 can stabilize the connection between the water pipe 28 and the mounting frame 35, and the mounting box 38 is arranged on the spraying mechanism 10 to increase the mounting stability of the internal components of the spraying mechanism 10, the mounting box 38 is fixedly connected with the water storage tank 8 through the connecting column 39, and the water storage tank 8 can collect the filtered rainwater, so that the rainwater can be used repeatedly and resources can be saved.
