Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0022] The present embodiment provides a building rainwater collecting and utilizing device, as shown in the figure, the building rainwater collecting and utilizing device comprises a fixing frame 2 and support frames 21 symmetrically distributed on the fixing frame 2, a water storage tank 1 is installed on the support frame 21, one end of the water storage tank 1 is connected with a drain pipe 5, and a water level sensor 3 is installed on the water storage tank 1. Figures 1-4

[0023] The fixing frame 2 is provided with a rainwater utilizing assembly, and one end of the water storage tank 1 is provided with a rainwater collecting assembly

[0024] The rainwater collecting assembly comprises a three-way electromagnetic valve 51 installed on the drain pipe 5 and a branch pipe 52 fixedly installed at a side water outlet of the three-way electromagnetic valve 51, the branch pipe 52 is sleeved with a sealing disc 55 at an end away from the three-way electromagnetic valve 51, a connecting pipe 4 is installed at one end of the water storage tank 1 close to the drain pipe 5, and the connecting pipe 4 is sleeved with a water receiving hopper disc 53 used for being connected with the sealing disc 55.

[0025] ​Specifically, the sealing ring of fluororubber material is arranged on the sealing disc 55, which is mainly used to form a seal after the sealing disc 55 is closed with the water bucket disc 53, so as to avoid leakage. The water level sensor 3 usually outputs an analog signal or a digital signal, which is connected to the input port of the controller PLC. The three-way electromagnetic valve 51 is driven by the output on-off signal of the controller, which controls the switching of the water path. The power line of the electromagnetic valve is connected to the output end of the controller. When the water level sensor 3 detects that the water level in the water storage tank 1 is too high, the sensor sends a signal to the controller, and the controller triggers the three-way electromagnetic valve 51 to switch to the drainage mode to connect the tapping pipe 52. The excess rainwater is discharged through the drain pipe 5 to avoid overflow. The sealing disc 55 is surrounded by a cylindrical handle on the outer periphery, which can be rotated by the staff to separate the sealing disc 55 from the water bucket disc 53.

[0026] The tapping pipe 52 is provided with a threaded surface 54, and the sealing disc 55 is provided with a threaded sleeve 56 for threaded connection with the tapping pipe 52. The inside of the water bucket disc 53 is provided with a fixing ring 532, and the inside of the fixing ring 532 is provided with a filter screen 533. The upper end of the filter screen 533 is fixedly provided with a handle 534.

[0027] More specifically, the water bucket disc 53 can guide the rainwater flowing in the same direction into the water storage tank 1, and the filter screen 533 can filter the rainwater during the guiding process to prevent fallen leaves or bird droppings on the roof from being guided into the water storage tank 1. The sealing disc 55 is threaded with the tapping pipe 52, which facilitates cleaning of the filter screen 533 and prevents the filter holes from being blocked due to long-term use.

[0028] The inside of the water bucket disc 53 is annularly provided with a plurality of limiting blocks 531, and the lower end of the fixing ring 532 is annularly provided with a plurality of assembly grooves 535 corresponding to the limiting blocks 531.

[0029] Further, the limiting blocks 531 arranged in the water bucket disc 53 are mainly used to facilitate the calibration and installation of the fixing ring 532.

[0030] The rainwater utilization assembly comprises a fixed plate 26 fixedly installed on the fixed frame 2, and a water pump 27 installed on the upper end of the fixed plate 26. The lower end of the water storage tank 1 is provided with a water outlet connected to the input end of the water pump 27. The water pump 27 is provided with two output ends. The fixed frame 2 is symmetrically provided with a plurality of water distribution pipes 24, and the water distribution pipes 24 are equally spaced and provided with a plurality of atomizing nozzles 25. The fixed frame 2 is symmetrically provided with a plurality of adjusting holes 22, and the adjusting holes 22 are detachably provided with a fixing seat 23. The water distribution pipes 24 are rotationally connected to the fixing seat 23.

[0031] Further, the double-output water pump 27 realizes irrigation and sprinkling functions in parallel, and through extraction of rainwater in the water storage tank 1, the water distribution pipe 24 and the atomizing nozzle 25 can realize the sprinkling operation of the community green plants, thereby improving the utilization rate of rainwater resources. In summer, the height and angle of the water distribution pipe 24 can be adjusted to make the atomizing nozzle 25 spray atomization in the air to cool the surrounding.

[0032] The two output ends of the water pump 27 are connected with the corresponding water distribution pipes 24 through the water guide hose 28.

[0033] It should be noted that the soft water guide hose 28 is used to connect the water distribution pipe 24, which can adapt to the height adjustment of the water distribution pipe 24.

[0034] In use, the water storage tank 1 is stably installed through the fixing frame 2 and the support frame 21. When it rains, rainwater enters the water collecting disc 53 through the sealing disc 55, and the filter screen 533 in the water collecting disc 53 intercepts large-particle impurities such as leaves and sand and finally guides them into the water storage tank 1. When the water level sensor 3 detects that the water level reaches the preset upper limit, the three-way electromagnetic valve 51 is triggered to switch to the drainage mode. When it is sunny, the water pump 27 sucks water from the bottom of the water storage tank 1, and through the water guide hose 28, the water is branched to two water distribution pipes 24, and the atomizing nozzle 25 on the water distribution pipe 24 pulverizes the water flow into micron-level water mist to irrigate the two-way green plants.

[0035] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto.
