[0002] Urban park green space, especially large park green space, plays an important role in maintaining the ecological balance of the city and beautifying the urban landscape. It is also an important place for citizens to get close to nature and carry out outdoor recreational activities. In recent years, various parks with water culture as the theme have continued to appear across the country. There are more and more artificial lakes and connected canals. In order to create flowing water landscapes, setting up waterfalls through overflow dams often becomes the focus of design.

[0003] As the operation time of closed water bodies increases, the water quality is prone to eutrophication, and some water purification projects are often involved to achieve the purpose of maintaining good water quality. At present, the above-mentioned waterfall landscape is only designed as a waterfall landscape effect. The formation of a waterfall generally requires a high drop, and there are few overflow dams that use the drop to set up water purification projects. Summary of the invention

A fixing plate 2025 is set at the other end of the fixing rod 2024, and the fixing plate 2025 is placed inside the positioning device 204. The fixing rod 2024 is placed in the middle groove 2041 of the positioning device 204. A screw 2026 is set on the fixing plate 2025, and the screw 2026 is fixed in the other two grooves 2042; the landscape purification box 300 is divided into a landscape filling area 302 and a water distribution area 303 by a partition 301. A filler 304 for purifying water quality is set in the landscape filling area 302, and landscape purification plants 305 are planted on the filler 304. A perforation 306 is set at the lower part of the partition 301, and a water outlet plate 307 in the water distribution area 303 is lower than the partition 301. There is a water-passing section 205 formed by a gap between the above-mentioned water retaining stone pier 102 and the positioning stone pier 203.

[0016] The bell mouth 2021 is connected to one end of the water pipe 206, and the other end of the water pipe 206 is placed at the lower part of the upstream section 500, so as to ensure that the water at the lower part of the upstream section 500 can also flow and maintain good water quality.

[0017] The circumference of the water inlet at the upper end of the bell mouth 2021 is greater than the sum of the distances between the water retaining stone pier 102 and the positioning stone pier 203, so that when the water level rises, most of the water will enter the bell mouth 2021 and flow away.

[0018] Baffles 207 are provided on both sides of the overflow top surface 101 to ensure that overflow water does not flow out from both sides.

[0019] The following is a detailed description of the use of the present invention.

[0020] Adjust the water level: Move the fixed plate 2025 up and down to a suitable position, and the fixing rod 2024 drives the bell mouth 2021 to move up and down to a suitable height. The hose 2023 can be extended and retracted up and down, and the fixed plate 2025 is fixed by bolts. The height of the bell mouth 2021 is adjusted, thereby achieving the adjustment of the water level of the upstream section 500.

[0021] The water flow of the upstream section 500, of which the upper part of the water flows into the bell mouth 2021 through the overflow, the lower part of the water flows into the bell mouth 2021 through the water guide pipe 206, and the water in the bell mouth 2021 flows into the hose 2023, and then enters the hole 201 through the pipe 2022, forming a waterfall landscape on the step 208 of the waterfall dam body 200. The other part of the water flows through the water section 205 between the stone piers 102 and 203, and enters the overflow top surface 101, and then the overflow top surface 101 and the baffles 207 on both sides jointly guide the water flow into the landscape purification box 300, and form a waterfall phenomenon. The water flow is purified by the filler 304 and microorganisms and the landscape purification plants 305 in the landscape filler area 302, and then passes through the perforation 306, enters the water distribution area 303, bypasses the water outlet plate 307 and downwardly forms a waterfall landscape, and enters the next landscape purification box 300; thus, the landscape purification box 300 is purified step by step, and a waterfall landscape is formed, and finally the water flows into the downstream section 400.

[0022] When the water flow in the upstream section 500 changes, the circumference of the water inlet at the upper end of the bell mouth 2021 is greater than the sum of the distances between the stone piers 102 and 203. The overflow section of the bell mouth 2021 is larger, and most of the liquid level above the bell mouth 2021 will overflow from the bell mouth 2021, so that the height of the water section 205 between the water retaining stone pier 102 and the positioning stone pier 203 does not change much, thereby ensuring that the amount of water entering the landscape purification box 300 is stable, so that the water purification effect of the landscape purification box 300 remains in the best state.

[0023] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
