Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rainwater collection, in particular to a rainwater collection system with an isolation structure. Background Art
[0002] Rainwater collection structure is a kind of water resource reuse. Many buildings are equipped with rainwater collection tanks on their roofs. Due to environmental pollution, the pollution degree of initial rainwater is relatively high, because the initial rainwater dissolves acidic gases, automobile exhaust, factory exhaust and other polluting gases in the air, and washes away pollutants on the ground, such as dust, oil, chemicals, etc. Generally, the initial rainwater will be discarded. The current rainwater collection device cannot make corresponding treatment for the initial rainwater, but directly mixes the initial rainwater and the later rainwater for use together.
[0003] Therefore, in order to correct the above defects, we propose a rainwater collection system with an isolation structure. Utility Model Content
[0004] The technical problem solved by the utility model is to provide a rainwater collection system with an isolation structure.

[0006] Furthermore, a drainage hose is connected to the bottom of the initial rainwater collection tank, a drainage valve is connected to the bottom of the side wall of the water storage tank, and the drainage hose is connected to the drainage valve.
[0007] Furthermore, a limit stop bar is installed on the inner wall of the water storage tank, and when the inlet end of the guide pipe is connected to the water inlet, one end of the lever arm just contacts the limit stop bar.
[0008] Furthermore, the outlet end of the water inlet is connected to a water guide pipe, and the water inlet is connected to the flow guide pipe through the water guide pipe.
[0009] Further, a rubber sleeve is connected to the outlet end of the water guide pipe. When the inlet end of the diversion pipe is butted against the water guide pipe, the rubber sleeve enters the inlet end of the diversion pipe.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0017] The present utility model provides a technical solution:
[0018] Please refer to Figure 1-2, A rainwater collection system with an isolation structure, which includes a water storage tank 1. An inlet 2 is connected to the upper end of the water storage tank 1. A drain pipe 3 is installed at the bottom of the water storage tank 1, and an overflow port is installed at the upper end of one side of the water storage tank 1. An initial rainwater isolation structure is arranged inside the water storage tank 1. The initial rainwater isolation structure includes an initial rainwater collection tank 5 arranged in the water storage tank 1 and a support system for installing the initial rainwater collection tank 5. The support system includes a shaft rod 12. A bearing is sleeved outside the shaft rod 12, and a lever arm 13 is sleeved outside the bearing. One end of the lever arm 13 is connected to a bracket 15, and the initial rainwater collection tank 5 is located inside the bracket 15. A counterweight 11 is hinged to the other end of the lever arm 13. A diversion pipe 8 is installed at the upper end of the lever arm 13. The outlet end of the diversion pipe 8 is connected to the initial rainwater collection tank 5, and its inlet end is movably docked with the inlet 2;
[0019] The initial rainwater enters the inside of the water storage tank 1 from the inlet 2. At the same time, due to the action of the counterweight 11, it pulls the lever arm 13 to rotate counterclockwise. The lever arm 13 drives the diversion pipe 8 and the initial rainwater collection tank 5 to rotate. The lever arm 13 rotates until it contacts the limit bar 10. At this time, the inlet end of the diversion pipe 8 is exactly docked with the inlet 2. The initial rainwater then enters the diversion pipe 8 from the inlet 2 and then enters the initial rainwater collection tank 5 from the diversion pipe 8. When there is more initial rainwater inside the initial rainwater collection tank 5, the weight of the initial rainwater collection tank 5 is greater than the weight of the counterweight 11. Then the lever arm 13 drives the diversion pipe 8 and the initial rainwater collection tank 5 to rotate clockwise. The inlet end of the diversion pipe 8 is separated from the outlet end of the inlet 2. Then the subsequent rainwater enters the water storage tank 1. Since the installation position of the drain valve 7 is relatively low, the initial rainwater in the initial rainwater collection tank 5 is discharged from the water storage tank 1 separately through the drain hose 6 and the drain valve 7.
[0020] Among them, the outlet end of the inlet 2 is connected to a guide pipe 4. The inlet 2 is docked with the diversion pipe 8 through the guide pipe 4. The outlet end of the guide pipe 4 is connected to a rubber sleeve 9. When the inlet end of the diversion pipe 8 is docked with the guide pipe 4, the rubber sleeve 9 enters the inlet end of the diversion pipe 8. The inlet end of the diversion pipe 8 is of a flared structure. When the lever arm 13 rotates counterclockwise, it will drive the inlet end of the diversion pipe 8 to contact the rubber sleeve 9. The rubber sleeve 9 quickly enters the inlet end of the diversion pipe 8 by virtue of its softness and restorability. In this way, the two can be quickly docked, and it is ensured that the initial rainwater will not penetrate at the docking place.
[0021] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
