For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components.

[0032] [First embodiment]

[0033] like Figure 1-8 The figure shows a foldable unpowered slow-release device provided by the first embodiment of the utility model. Figure 3-4 As shown, the device includes a water inlet 1, and a filter screen is arranged at the position of the water inlet 1. Large particles of impurities in the water body cannot enter the water inlet 1 after being filtered through the filter screen, thereby further ensuring the cleanliness of the incoming water; the rear end of the water inlet 1 is connected to a flow control component 2, and the water inlet 1 is connected to the inside of the flow control component 2.

[0034] like Figure 5 As shown, the flow control component 2 in this embodiment includes a flow control tube 21, a flow control plate 22 is fixed inside the flow control tube 21, a flow control hole 23 is opened inside the flow control plate 22, and the aperture of the flow control hole 23 is larger than the aperture of the filter screen, so that small particle impurities entering the flow control component 2 from the water inlet 1 can be discharged from the flow control hole 23, avoiding blockage caused by small particle impurities failing to pass through the flow control hole 23.

[0035] A float 3 is fixedly provided on the top of the flow control component 2 to increase the buoyancy required for the unpowered slow-release device to float. In order to increase the contact area with the water body, the float 3 in this embodiment is preferably set to a spherical shape.

[0036] In addition, a support member 8 is fixedly connected to the bottom of the flow control component 2, and the support member 8 is not connected to the interior of the flow control component 2. The support member 8 prevents the filter net set at the water inlet 1 from directly contacting the bottom impurities of the water storage space A when it falls, thereby damaging the filter net.

[0037] like Figure 3-4 As shown, the rear end of the flow control component 2 in this embodiment is connected to multiple sections of flow pipes 5 that are interconnected. The front end of the flow pipe 5 is connected to the interior of the flow control component 2, and the rear end is connected to the water outlet 7. The multiple sections of the flow pipe 5 can rotate relative to each other. After passing through the flow control component 2, water flows out slowly, evenly and at a controllable flow rate into the interior of the flow pipe 5 and is finally discharged from the water outlet 7 to the rainwater pipe network connected thereto.

[0038] The flow tube 5 in this embodiment is made of hollow plastic material. Even during the slow release process, only a small amount of liquid flows through the flow tube 5. Therefore, the flow tube made of hollow plastic material can provide a certain buoyancy for the floating of the device.

[0039] like Figure 4 As shown, the multiple sections of flow tubes 5 are connected through an elbow 4 and a rotating member 6. One end of the elbow 4 is fixedly sleeved on the end of the flow tube 5, and the other end is movably sleeved on the end of the rotating member 6. The rotating member 6 can rotate around the elbow 4 to achieve relative rotation between the multiple sections of flow tubes 5. In this embodiment, the elbow 4 is a right-angle elbow, and the maximum rotation angle of the rotating member 6 relative to the elbow 4 can be pre-set to ensure that the posture of the multiple sections of flow tubes 5 can be restored after floating and falling.

[0040] The initial state of the foldable unpowered slow-release device provided in this embodiment installed in the water storage space A is as follows: Figure 6 As shown in the figure, when the runoff rainwater enters the water storage space A, the foldable unpowered slow-release device slowly floats to the position shown in the figure. Figure 7 As shown in , the supernatant of the precipitated rainwater is slowly discharged into the rainwater pipe network B.

[0041] like Figure 8 As shown, the foldable unpowered slow-release device provided in this embodiment can also be used in conjunction with the unpowered pollution control device D to discharge the liquid with a high pollution content after settling in the lower part of the water storage space into the sewage pipe network C.

[0042] The axial length and the number of the flow tubes 5 in this embodiment can be set accordingly according to actual needs. Fig. 9 The figure shows a top view of the structure of another embodiment provided by the utility model, in which an implementation method of five flow tubes 5 is provided. Those skilled in the art should know that according to actual needs, the axial length and the selected number of the flow tubes 5 can also be selected to other suitable values.

[0043] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
