When the bottom surface of the vibration device 4 is separated from the bottom surface of the depression 31, water can flow out of the water outlet 32. Due to the flow of water at the water outlet 32, the vibration device 4 can vibrate when supplying water. The top surface of the vibration device 4 contacts the bottom surface of the first filter material layer 23. When the vibration device 4 vibrates, the first filter material layer 23 and the second filter material layer 24 are driven to vibrate in turn, and the blockages in the first filter material layer 23 and the second filter material layer 24 are dispersed by vibration, thereby achieving the effect of alleviating the blockage of the filter material.

[0110] Reference Figure 2 The recess 31 is a cubic structure, and the vibration-following device 4 matches its shape, so the vibration-following device 4 can be placed inside the recess 31 .

[0111] Reference Figure 3 The vibration device 4 includes a vibration block 41 and an elastic connector 42. The bottom surface of the vibration block 41 is a plane for contacting the inner bottom surface of the recess 31. The top surface of the vibration block 41 contacts the first filter material layer 23. The side wall of the vibration block 41 is connected to one end of the elastic connector 42, and the other end of the elastic connector 42 is connected to the inner side surface of the adjacent recess 31.

[0112] The material and structure of the vibration block 41 of this embodiment are different from those of the embodiment 1. In this embodiment, the structure of the vibration block 41 is shown in FIG. Figure 7, the vibration block 41 is hollow, the side wall of the vibration block 41 is made of hard material, such as stainless steel, and the top and bottom surfaces of the vibration block 41 are made of soft materials, such as elastic rubber or non-woven fabric. A vibration bar 43 is arranged inside the vibration block 41, and the bottom surface of the vibration bar 43 is arranged in a regular pattern with different heights, such as a wave-shaped arrangement, and adjacent vibration bars 43 are connected by connecting bars 44, such as elastic rubber strips, springs or chains. When water flows out of the water outlet 32, the water flow is turbulent, especially when high-pressure water flows with great kinetic energy, which first drives the vibration bar 43 closest to it to vibrate, and then drives other vibration bars 43 to vibrate. Under the action of the connecting bar 44, there is also a coordinated vibration effect between adjacent connecting bars 44. A telescopic member 45 is provided between the vibration bar 43 and the top surface of the vibration block 41, or between the vibration bar 43 and the bottom surface of the vibration block 41, such as a spring.

[0113] Compared with the first and second embodiments, the telescopic member 45 of the present embodiment has a telescopic vibration function, which can cooperate with the vibration of the vibration bar 43 to prolong the vibration time.

[0114] Example 4

[0115] A method of a wetland ecological water level regulation system is to supply water to a water pipe 3 through a water supply pool 1. The water supply can be continuous or intermittent. When the water level reaches a predetermined height, the water supply is stopped.

[0116] It should be noted that when the present invention involves a numerical range, it should be understood that the two endpoints of each numerical range and any value between the two endpoints can be selected. Since the steps and methods used are the same as those in the embodiments, in order to avoid redundancy, the present invention describes a preferred embodiment. Although the preferred embodiments of the present invention have been described, once those skilled in the art know the basic creative concept, they can make additional changes and modifications to these embodiments, and these changes and modifications all fall within the scope of the present invention.
