[0002] A rain garden is a naturally formed or artificially excavated shallow green space that is used to collect and absorb rainwater from the roof or the ground. Through the combined effects of plants and sand, the rainwater is purified and gradually infiltrated into the soil to conserve groundwater, or to replenish urban water such as landscape water and toilet water. It is an ecologically sustainable rainwater control and rainwater utilization facility. From the inside to the outside, a rain garden is generally composed of a gravel layer, a sand layer, a planting soil layer, a covering layer and a water storage layer. At the same time, perforated pipes are provided to collect rainwater, and overflow pipes are provided to remove water that exceeds the designed water storage capacity.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] The utility model provides a technical solution: Figure 1-Figure 4 As shown, in this embodiment, a device for extracting liquid samples in each structural layer of a rain garden includes a covering layer 1, a soil layer 2 is arranged at the bottom of the covering layer 1, a sand and stone layer 3 is arranged at the bottom of the soil layer 2, and a gravel layer 4 is arranged at the bottom of the sand and stone layer 3. Water storage pipes 5 are fixedly installed inside the covering layer 1, the soil layer 2, the sand and stone layer 3 and the gravel layer 4. A filter screen 6 is arranged at one end of the water storage pipe 5, and a connecting pipe 9 is threadedly connected to the other end of the water storage pipe 5. A sealing component is arranged inside the connecting pipe 9. A cover plate 18 is rotatably connected to the top of the connecting pipe 9. A collecting pipe 8 is penetrated inside the covering layer 1, the soil layer 2, the sand and stone layer 3 and the gravel layer 4, and a water intake component is arranged inside the collecting pipe 8.

[0021] First, rainwater enters through the covering layer 1 and then is filtered layer by layer through the soil layer 2, the sand and stone layer 3 and the gravel layer 4. Finally, the rainwater is purified and gradually infiltrated into the soil to conserve groundwater or replenish urban water such as landscape water and toilet water. When the rainwater infiltrates, the rainwater enters the interior of the water storage pipe 5 through the filter screen 6. The water storage pipe 5 is arranged in the covering layer 1, the soil layer 2, the sand and stone layer 3 and the gravel layer 4. This makes it more convenient to collect rainwater between the layers. Then, under the action of the sealing component, the rainwater stays in the water storage pipe 5. This facilitates the convenience of subsequent water collection and detection, thereby increasing the practicality of the device. Then, the cover plate 18 of the connecting pipe 9 is opened, and the handheld water collection component is placed in the connecting pipe 9. Then, one end of the handheld water collection component contacts the sealing component. Then, the water collection component is started to collect the rainwater from each layer inside the water storage pipe 5 into the interior of the water collection component, thereby reducing the problem that the effect of the existing rainwater cannot be detected or is difficult to detect, thereby further increasing the practicality of the device.

[0022] like Figure 1-Figure 4As shown, the sealing assembly includes a fixing frame 11, which is fixedly connected to the inside of the connecting tube 9, a fixing rod 13 is fixedly connected to one side of the fixing frame 11, and a stopper 14 is fixedly connected to one end of the fixing rod 13. The sealing assembly also includes a displacement plate 12, which is slidably connected to the inside of the connecting tube 9, a spring 10 is fixedly connected between one side of the displacement plate 12 and the fixing frame 11, and sealing gaskets are arranged on the outside of the stopper 14 and the displacement plate 12. The water intake assembly includes a needle tube 17, which is arranged in the inside of the collecting tube 8, and a manual telescopic rod 7 is fixedly connected to the outside of the needle tube 17. The water intake assembly also includes an electric telescopic rod 15, which is fixedly installed on the top of the needle tube 17, and a piston 16 is slidably connected to the inside of the needle tube 17, and one end of the movable rod of the electric telescopic rod 15 is fixedly connected to the top of the piston 16.

[0023] When taking water, hold the manual telescopic rod 7 and then put the needle tube 17 into the connecting tube 9, then make one end of the water inlet of the needle tube 17 contact the displacement plate 12 on one side of the connecting tube 9, and then drive the spring 10 to compress, so that the displacement plate 12 and the block 14 are separated. At this time, the rainwater inside the water storage pipe 5 will flow out through the holes inside the displacement plate 12, and then start the electric telescopic rod 15 to move the piston 16 inside the needle tube 17, so that the rainwater can be quickly pumped out of the water storage pipe 5.

[0024] The utility model provides a device for extracting liquid samples in each structural layer of a rain garden, and the specific working principle is as follows: first, rainwater enters the interior of the water storage pipe 5 through the filter screen 6, and the water storage pipe 5 is arranged in the covering layer 1, the soil layer 2, the sand and stone layer 3 and the gravel layer 4, so that the rainwater between the layers can be collected more conveniently, and then, when taking water, the needle tube 17 is placed into the interior of the connecting tube 9 by holding the manual telescopic rod 7, and then one end of the water inlet of the needle tube 17 is brought into contact with the displacement plate 12 on one side of the connecting tube 9, and then the spring 10 is driven to be compressed, so that the displacement plate 12 is separated from the block 14, and then the rainwater in the water storage pipe 5 will flow out through the hole in the displacement plate 12, and then the piston 16 is driven to move inside the needle tube 17 by starting the movable rod movement of the electric telescopic rod 15, so that the rainwater can be quickly extracted from the water storage pipe 5.

[0025] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
