DETAILED DESCRIPTION

[0022] The following will be combined with the embodiments to clearly and completely describe the technical solution 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 of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0023] like Figures 1 to 4 As shown, a rainwater regulation and storage system includes a water collection well 1, a flow abandonment device 2, a rainwater filter 3 and a water storage well 4 which are sequentially connected by pipelines. Among them, the flow abandonment device 2 and the rainwater filter 3 are both existing technologies and will not be repeated in this disclosure. Simply put, the flow abandonment device 2 can abandon the initial rainwater, and the rainwater filter 3 is used to filter the rainwater. In detail, a guide pipe 5 is connected to the water inlet of the water collection well 1, and the inlet end of the guide pipe 5 is connected to the roof. The rainwater drainage from the roof can be directly introduced into the guide pipe 5 and collected into the water collection well 1; a lifting pump 7 is provided in the water storage well 4, and the output end of the lifting pump 7 is connected to a water purification device 8, which is also existing technology, so it will not be repeated. The output end of the water purification device 8 is connected to the water supply system 25. And a sewage interception device 6 is provided in the water collection well 1, and the large volume impurities carried by the rainwater are intercepted and filtered by the sewage interception device 6.

[0024] For example, the water supply system 25 can be an irrigation system, a toilet flushing system or a pool water replenishment system. Meanwhile, the rainwater storage system disclosed in the present invention is buried underground, thereby saving ground space.

[0025] When in use, the rainwater from the roof enters the water collection well 1 through the diversion pipe 5, and then the water flows through the water collection well 1 into the flow abandonment device 2 to abandon the initial rainwater, and the clean rainwater in the later stage will be filtered by the rainwater filter 3 and stored in the water storage well 4. When the water in the water storage well 4 needs to be used, the water can be pumped into the water purification device 8 by the lifting pump 7 for purification before use, and finally the water can be pumped into different water supply systems 25 for different purposes.

[0026] In some embodiments, the water storage well 4 is constructed to include a water storage part and a mounting part 10 located at the bottom of the water storage part, and a water intake 9 connected to the ground is also configured at the top of the water storage part, and the lifting pump 7 is installed in the mounting part 10. Among them, artificial water intake in the water storage well 4 can be achieved through the water intake 9; the lifting pump 7 is installed in the mounting part 10 at a lower position, so it is easier for the lifting pump 7 to lift and utilize the water in the water storage well 4.

[0027] In some embodiments, a partition 11 is provided in the water collection well 1. Specifically, the partition 11 is located below the water inlet and the water outlet of the water collection well 1, and a mounting hole is also configured on the partition 11. The sewage interception device 6 includes a sewage interception hanging basket 12 embedded in the mounting hole, and a filter plate 13 opposite to the water outlet of the water collection well 1 is also provided on the top surface of the partition 11, and the preliminary filtration of impurities carried by rainwater is achieved through the cooperation of the filter plate 13 and the sewage interception hanging basket 12.

[0028] For example, a mounting plate 14 is provided at the wellhead of the water collection well 1, a mounting opening 15 is provided through the mounting plate 14, and a mounting groove 16 is correspondingly provided on the top surface of the partition 11. Therefore, the filter plate 13 can preferably be detachably connected between the mounting opening 15 and the mounting groove 16, that is, the filter plate 13 can be inserted into the mounting opening 15 from top to bottom, and finally the two ends of the filter plate 13 are respectively confined in the mounting opening 15 and the mounting groove 16. Therefore, the water flow entering the water collection well 1 will pass through the filter plate 13 before it can pass to the water blowing port side.

[0029] In a preferred embodiment, the filtering portion of the filter plate 13 is configured as an arc that is concave along the water flow direction, so that the impact force of the water flow on the filter plate 13 is effectively reduced, and the filter plate 13 is not easily deformed under the water pressure.

[0030] In some embodiments, a connecting rod 18 is provided on the top surface of the filter plate 13, and a connecting rod 2 19 is connected between the connecting rod 18 and the sewage interception basket 12. For example, the connecting rod 2 19 is detachably connected to the sewage interception basket 12 by fasteners. It can be understood that when cleaning and maintaining the sewage interception device 6, the connecting rod 18 can be lifted to realize the simultaneous lifting of the filter plate 13 and the sewage interception basket 12, especially solving the problem that the sewage interception basket 12 is not easy to lift. Preferably, a handle 17 is provided on the top surface of the connecting rod 18, and of course the handle 17 can also be provided on the top surface of the filter plate 13, and the sewage interception device 6 can be lifted conveniently and labor-savingly by the handle 17.

[0031] For example, the connecting rod 18 is also detachably connected to the filter plate 13 by a fastener. Therefore, the connecting rod 18 can also be separated from the filter plate 13 to realize the separate maintenance of the intercepting hanging basket 12.

[0032] In a preferred embodiment, a rotating sleeve 20 is also rotatably provided on the connecting rod 19, and a cleaning rod 21 and a flow-breaking rod 22 are provided on the side wall of the rotating sleeve 20. For example, a cleaning rod 21 is also provided on the part of the rotating sleeve 20 inside the sewage interception hanging basket 12. It can be understood that in the daily maintenance of the sewage interception device 6, the rotating sleeve 20 can be rotated manually, for example, a hand wheel (not shown) can be provided on the top side wall of the rotating sleeve 20 to facilitate the rotation of the rotating sleeve 20, and the two cleaning rods 21 can clean the filter surfaces of the sewage interception hanging basket 12 and the filter plate 13 respectively, thereby reducing the blockage of the sewage interception device 6 to achieve the purpose of reducing the maintenance cycle.

[0033] In addition, a plurality of hook blades 23 are vertically arranged on the side wall of the flow-breaking rod 22. In the process of collecting rainwater, impurities such as plastic products or clumps of hair may be entrained in the rainwater, and these impurities can easily cause blockage of the sewage interception device 6. With the setting of the hook blades 23, the water flow entering the water collection well 1 from the water inlet will first impact the hook blades 23. On the one hand, the flow-breaking rod 22 can divert the water flow, thereby reducing the impact force of the water flow on the sewage interception device 6, so as to increase the service life of the sewage interception device 6; on the other hand, at this time, the impurities in the rainwater will be hooked by the hook blades 23 again and are not easy to cause blockage of the sewage interception device 6.

[0034] Correspondingly, the rotating sleeve 20 is provided with a stopper 24 for circumferential positioning thereof. For example, the stopper 24 may include an adjusting bolt threadedly connected to the connecting rod 18, and a stopper hole is provided on the rotating sleeve 20. The adjusting bolt can be screwed and inserted into the stopper hole to stop the rotating sleeve 20 circumferentially and keep the flow-breaking rod 22 in a relative use state to the water inlet.

[0035] In some embodiments, a fan blade portion (not shown) may be further provided on the rotating sleeve 20, and the automatic rotation of the rotating sleeve 20 may be driven by the impact of water flow on the fan blade portion. Therefore, during the rainwater collection process, the cleaning rod 21 may clean the sewage interception device 6 automatically.

[0036] For example, the plurality of hook blades 23 preferably include a straight hook unit 26 and a curved hook unit 27 in the vertical direction. The hook body of the straight hook unit 26 is substantially parallel to the water flow direction between the water inlet and the water outlet, and the hook body of the curved hook unit 27 is configured to be tilted toward the water inlet. It can be understood that in different rainwater flow periods, for example, when the amount of rainwater is small, the water flow falls on the curved hook unit 27, and the tilted hook body is easier to hook impurities; when the amount of rainwater is large, the water flow falls on the straight hook unit 26, and the hook body of the straight hook unit 26 is easier to hook impurities.

[0037] The above is only a preferred embodiment of the utility model. It should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not deviate from the spirit and scope of the utility model, and should be within the scope of protection of the claims attached to the utility model.
