Description

Technical Field

[0001] The invention relates to the field of environmental technology, and in particular to a three-level gate-type inland river valley flood avoidance dark harbor ecological protection system. Background Art

[0002] In order to accelerate the recovery of the damaged ecosystem, artificial measures can also be used to serve the healthy operation of the ecosystem. Accelerating recovery is called ecological restoration. "Ecological restoration" refers to restoring the natural ecosystem through artificial methods in accordance with natural laws. The goal of ecological restoration is not to plant as many species as possible, but to create good conditions to promote a community to develop into a complete ecosystem composed of local species. Or to provide a corresponding habitat for various local animals.

[0003] Some inland river valleys in my country often experience floods in the summer. During the floods, the water level will rise, and the water flow will sweep away or kill a large number of fish and aquatic organisms that cannot escape. In winter or when the weather is dry, the water volume will drop sharply, the water level will drop, and the river surface will shrink and narrow. Only a very small number of fish that have successfully escaped will remain in the river water flowing all year round to continue to live and reproduce. In severe droughts, some rivers will even dry up, which will directly affect the survival of fish. The reduction of other aquatic plants and animals, including fish, will further affect the survival and reproduction of related terrestrial plants and animals, easily causing ecological imbalance, and it will take a long time for the natural ecological self-repair.

[0024] The present invention will be further described below in conjunction with the accompanying drawings.

[0025] Embodiment 1: According to Figure 1 to Figure 2The three-stage gate-type inland river valley flood avoidance dark harbor ecological protection system shown in the figure includes a river channel 1 and a slope protection 10. The river channel 1 includes a dry season river channel 2. Between the dry season river channel 2 and the slope protection 10 is a flood riverbed 3, and the flood riverbed 3 can also be called a flood floodplain. The inland river valley in this embodiment is a river floodplain valley. A dark harbor 4 is built below the flood riverbed. The dark harbor 4 includes a dark harbor cabin 41. The dark harbor cabin 41 has a first waterway 5. The first waterway 5 connects the river channel 1 and the dark harbor cabin 41. The first waterway 5 connects the river channel 1 and the dark harbor cabin 41. A water channel 5 includes a first sluice gate 51, and the dark harbor body 41 is built with a second water channel 6, which connects the river channel 2 and the dark harbor body 41 during the dry season, and the second water channel 6 is provided with a second sluice gate, and the second water channel 6 is located below the first river channel 5; the dark harbor body 41 is provided with an open channel waterway 8 and an infiltration channel waterway 7, and the infiltration channel waterway 7 is provided with an infiltration pipe, and the open channel waterway 8 connects the upstream water source of the river channel 1 and the dark harbor body 41, and the open channel waterway 8 includes a third sluice gate, and the infiltration channel waterway 7 includes a fourth sluice gate.

[0026] In this embodiment, the end of the first water channel 5 close to the river channel 1 is lower than the end of the second water channel 6 close to the river channel 1 is lower than the end of the second water channel 6 close to the dark harbor cabin 41. The first water channel 5 can provide an escape channel for aquatic animals such as fish in the high water level river channel during floods. They can escape to the dark harbor cabin 41 with a relatively stable water flow environment through the first water channel 5 to avoid being washed away by the flood.

[0027] In this embodiment, the dark harbor cabin 41 is located one meter below the flood impact beach soil layer of the flood riverbed 3. The dark harbor cabin 41 is built one meter below the flood impact beach water layer. At this position, the constructed dark harbor cabin 41 will be more solid, and it will not be affected by the risk of collapse of the surrounding soil layers, will not be affected by the impact of floods, and the original surface plant and animal ecology can be maintained thereon.

[0028] By constructing a dark harbor cabin at this location, the dark harbor can be deeply developed without affecting the river ecology, and a "water park" can be built on it.

[0029] In this embodiment, one end of the open channel waterway 8 and the infiltration channel waterway 7 connecting the dark harbor hull 41 is located above the flood level 11 of the river 1, and the distance between the open channel waterway 8 and the infiltration channel waterway 7 is greater than half of the flood level 11. The open channel waterway 8 and the infiltration channel waterway 7 constructed in this embodiment can replenish the ecological water source above the flood level for the dark harbor hull 41, and can replenish water for the river 1 during the dry season, providing sufficient protection for the organisms in the river 2 during the dry season. The flood level in this embodiment is the average height of the water level in the flood season of the river in the past 10 years.

[0030] In this embodiment, one end of the first river channel 5 connected to the river channel 1 is located above the dry season river channel 2, one end of the first river channel 5 connected to the dark port cabin 41 is located below the third gate and the fourth gate, and one end of the second river channel 6 connected to the river channel 1 is located below the dry season water level 12 of the river channel 2. This design can ensure that the water source in the dark port cabin during the dry season can flow into the dry season river channel to replenish the water source for the dry season river channel. And when the ecological water quality of inland rivers is normal, it can provide a free connection channel for fish and other aquatic organisms to the river channel or the dark port cabin. The dry season water level in this embodiment is the average height of the dry season river water level during the dry season in the past 10 years.

[0031] In this embodiment, one end of the first river channel 5 and the second river channel 6 connecting to the dark harbor cabin is built on the harbor wall of the dark harbor cabin 41.

[0032] In this embodiment, a nest hole 9 is provided on the inner wall of the dark harbor cabin 41. The provided nest hole can increase the space of the dark harbor cabin and can provide certain protection for small aquatic animals.

[0033] When the present invention is implemented, the third gate and the fourth gate are closed before the flood season of the river, and the seepage channel 7 and the open channel 8 are stopped from providing water to the dark port cabin 41. When the flood comes, the first gate 51 is opened, and the fish and other aquatic organisms in the river can escape through the first river 5 to the dark port cabin 41 where the water flow is more stable and the fluctuation is smaller. The opening of the first waterway 4 can provide a reverse escape channel for the fish and the organisms. When the water level in the dark port cabin 41 is abnormal, the first gate 51 is closed. When it is the dry season, the second gate 61, the third gate, and the fourth gate can be opened to provide water for the dry season river 2 through the second channel 6; or when the ecological water quality of the inland river is normal, the second gate 61 is opened to provide a free connecting channel for fish and other aquatic organisms to the river 1 or the dark port cabin 41. When the natural fish in the inland river are threatened by the flood, the second gate 61 is closed in time and the first gate 51 is opened.

[0034] The present invention provides protection for the inland river valley ecosystem during flood and dry seasons through a combination of light and dark, high-position slope protection, and clear water sluices, so as to help increase the speed of its ecological restoration.

[0035] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
