Problems solved by technology

[0003] The object of the present invention is to address the deficiencies in the above-mentioned technologies, and propose an ecological transformation device for straight-bank rivers, aiming to solve the above-mentioned problems caused by the change of the channel shape of the above-mentioned "cutting bends and straightening" channels on the water ecology. The damage is difficult to recover in a short time and when the water level of the river drops, the habitat of aquatic plants is prone to wither due to dehydration and exposure to the sun

Embodiment 1

[0033] Such as Figure 1 to Figure 9 As shown, the present invention provides a kind of straight-bank river channel ecological transformation device, including the water permeable flow guide device 1 arranged on both sides of the river channel body, the water permeable flow guide facilities and the embankment of the river channel body are enclosed into a relatively closed still water area; Aquatic organisms are placed in the flow device 1, wherein the aquatic plants are emergent or submerged plants suitable for growing in the location of the facility, and the aquatic animals are filter-feeding fish, shellfish or crabs, etc. that are suitable for growing and breeding in the location of the facility; The diversion device 1 is used to provide shelter for aquatic plants and aquatic animals; the permeable diversion device 1 is arranged alternately along the embankment direction on both sides of the river body, so as to constrict the water body of the river channel into an "S" shape,...

Embodiment 2

[0039] Such as figure 1 and Figure 10 As shown, the difference between this embodiment and Embodiment 1 is that the permeable flow guide device 1 includes a frame 11, an upper fixed rope 14, a lower fixed rope 15, a floating ball 16, a tight net 17 and a weight 18, and the upper fixed rope 14 and The lower fixed rope 15 is connected to the bank of the river body to form a V-shaped structure. The upper fixed rope 14 and the lower fixed rope 15 are nylon ropes with good anti-corrosion performance and high strength. The upper fixed rope 14 and the lower fixed rope 15 are fixed on the straight bank of the river body. As the skeleton rope of the fixed water-permeable flow guide device 1; the frame 11 is connected between the upper fixed rope 14 and the lower fixed rope 15, and the frame 11 can be a high-strength plastic net to serve as the protective support net of the water-permeable flow guide device 1; The ball 16 is connected to the upper fixed rope 14, and the floating ball ...

Embodiment 3

[0044] Such as Figure 4 to Figure 9 As shown, in combination with the technical scheme of embodiment 1 or embodiment 2, in this embodiment, the straight pipe 4 is provided with a spiral pusher blade 9, and the spiral pusher blade 9 can transfer the river water from the straight pipe 4 during the rotation of the drainage blade. The first buoyancy block 41 is provided at the end of the straight pipe 4, and the first buoyancy block 41 is connected with the straight pipe 4 through the round pipe 8; the other end of the straight pipe 4 is connected with a plastic bearing 20 The buoyancy limiting member 42 is slidably disposed in the end of the frame 11; the buoyancy limiting member 42 includes a sliding part 421 and a second buoyancy block 422, and the sliding part 421 is slidably sleeved on the end of the frame 11 On both sides, the second buoyancy block 422 is connected to the upper end surface of the sliding part 421, and the circular pipe 8 is connected between the sliding par...

Abstract

The invention discloses an ecological transformation device for straight-bank rivers, which comprises water-permeable and diversion devices arranged on both sides of the river body, the water-permeable and diversion facilities and the embankment of the river body are enclosed to form a relatively closed still water area; There are aquatic organisms; the permeable and diversion devices are arranged alternately along the embankment direction on both sides of the river channel body, so as to constrict the water body of the river channel in an "S" shape; the permeable and diversion devices are located on the impacting side of the river channel water body and are provided with flow blocking parts; the present invention Provide a suitable habitat for aquatic organisms and improve the landscape effect of the river; effectively purify the river water and promote the healthy development of the river water ecosystem; set up drainage impellers to reduce the impact of water level drop on aquatic plants; the flow blocking parts adjust their speed according to the water flow, In order to reduce the impact of water flow on the water-permeable flow guide device, effectively improve the strength of the water-permeable flow guide device and slow down the impact of water flow on aquatic animals and plants.

Description

technical field [0001] The invention relates to the technical field of river ecological transformation, in particular to a device for ecological transformation of straight-bank rivers. Background technique [0002] River water is an important part of surface water, and it is also an important treatment object in the field of black and odorous water treatment and water environment restoration. Due to historical reasons and affected by the development of urbanization, many rivers in my country, especially inland rivers in cities, have been "truncated and straightened", resulting in the disappearance of the natural curved shape of the river, the degradation of the river water ecosystem, the decline in the self-purification capacity of the water body, and the urban life. The amount of pollution discharged into the river by sewage and initial rainwater far exceeds the pollution-holding capacity of the river, causing the river to be black and smelly. In recent years, my country ha...
