Description

Technical Field

[0001] The present invention relates to the technical field of three-habitat ecological dwelling, and in particular to a modular multi-habitat ecological dwelling system. Background Art

[0002] In recent years, with the increasing demand for water ecological restoration, artificial wetlands, floating islands, fish reefs and other technologies have been widely used in the fields of pollution control and biodiversity restoration. Traditional technologies mostly use a single functional module design, for example:

[0003] 1. Floating island system: With aquatic plant planting as the core, pollutants are absorbed through plant roots, but it lacks the integration of bird habitats, fish shelters and other functions, and there is no synergistic effect between the floating island structure and the underwater ecological layer;

[0004] 2. Fish reef system: using concrete or stone to form an underwater shelter, but only for benthic organisms, and cannot take into account the needs of surface and aerial organisms;

[0005] 3. Isolation protection net device: A protection net with a fixed aperture is used to physically isolate the fish school, but the net body is highly rigid and lacks elastic buffering, which can easily cause structural damage or damage to young fish due to water level fluctuations.

[0006] The main defects of the prior art are:

[0007] Ecological layer fragmentation: the habitats in the air (birds), water surface (plants), water body (fish) and bottom (benthic organisms) are independent of each other and cannot form an organic synergy of the vertical ecological chain;

[0008] Single function: A single module can only achieve a single function such as purification, shelter or habitat. The system has weak resistance to environmental disturbances and has limited effect on improving biodiversity.

[0009] Insufficient protection for juveniles: The aperture of traditional isolation and protection nets is fixed and lacks elasticity. Juvenile fish are easily impacted by water flow or attacked by natural enemies, and the survival rate is less than 50%;

[0010] Poor structural stability: The floating island and the fish reef adopt a split design with weak physical connection, which makes them prone to displacement or capsizing in extreme weather.

[0011] The disclosure of the above background technology content is only used to assist in understanding the inventive concept and technical solution of the present invention. It does not necessarily belong to the prior art of this patent application, nor does it necessarily provide technical guidance.

DETAILED DESCRIPTION

[0041] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0042] In view of the three core pain points of "functional fragmentation, weak protection, and delayed purification" in water ecological restoration, Figure 1-11As shown, the present invention provides a modular multi-habitat ecological habitat system, including: a vertical ecological chain structure, which is composed of a bird habitat pole assembly 7, an aquatic plant floating bed assembly 1, a juvenile fish protection isolation protection net assembly 2 and a benthic fish reef assembly 3 from top to bottom.

[0043] The present invention proposes a modular multi-habitat ecological habitat system, which coordinates bird habitat, plant purification, juvenile fish protection and benthic organism habitat by constructing a vertical ecological chain structure, thereby realizing the coordinated symbiosis of "water-land-air" amphibians. This can integrate the multi-dimensional ecological environment, strengthen the synergistic effect of the ecological chain, and improve the stability of the system, providing an innovative solution for the long-term stability of artificial water restoration and the improvement of biodiversity.

[0044] Preferably, if Figure 2 As shown, the bird habitat pole assembly 7 includes: a pole 13, a first electrically driven rotator 10 is provided on the pole 13, a rotatable connector 12 with self-damping is provided at one end of the pole 13, the pole 13 is connected to the cross bar 11 through the rotatable connector 12 with self-damping, the rotation trigger threshold of the cross bar 11 is 200-400g, the surface of the cross bar 11 is provided with a bionic anti-slip pattern, the other end of the pole 13 is provided with a three-way base 9, and the pole 13 is connected to the tube base 8 on the aquatic plant floating bed assembly 1 through the three-way base 9;

[0045] The vertical pole 13 can be rotated by the first electric drive rotator 10 or manually driven. The bird habitat vertical pole assembly 7 can drive the rotation of the vertical pole 13 through the first electric drive rotator 10 according to the plant growth conditions, weather and other conditions, and adjust the direction of the vertical pole 13. The horizontal bar 11 can adjust the angle by gravity through the rotatable connector 12 with self-damping according to the number of birds to prevent birds from gathering. The vertical pole 13 and the horizontal bar 11 cooperate with each other to prevent bird droppings from accumulating on the floating bed.

[0046] The vertical pole 13 is connected to the aquatic plant floating bed assembly 1 as a core supporting structure to provide a vertical habitat for birds and ensure the stability of the system in a water environment;

[0047] The trigger threshold (200-400 g) of the crossbar 11 rotation matches the average weight of an adult bird. When a bird attempts to build a nest, the rotatable connector 12 with built-in damping releases the damping, causing the crossbar 11 to swing at an angle of 5°-10°, destroying the stability of the nest.

[0048] The surface of the crossbar 11 is provided with bionic anti-skid patterns, and the bionic anti-skid patterns on the surface of the crossbar 11 (such as concave-convex textures or bark-like coatings) increase the bird's grip and prevent it from slipping; the rotatable connector 12 with self-damping allows the crossbar 11 to swing slightly when there is wind or bird activity, reducing structural stress and avoiding the risk of breakage caused by rigid connection;

[0049] The other end of the vertical pole 13 is provided with an aquatic plant floating bed assembly 1 and connected to the aquatic plant floating bed assembly 1. The bottom end of the vertical pole 13 is anchored to the aquatic plant floating bed assembly 1 to form a "water surface-air" linkage system;

[0050] The vertical pole 13 is connected to the pipe base 8 through the three-way base 9, forming an "air habitat-water surface purification" linkage structure. The bird excrement directly enters the floating bed area after flushing, and is absorbed and transformed by the plant roots, thereby improving the ammonia nitrogen removal rate.

[0051] Preferably, the aquatic plant floating bed assembly 1 includes: a plurality of polygonal floating plates, the plurality of polygonal floating plates are spliced ​​to form a floating island, the polygonal floating plates include: a hexagonal floating plate 14 and a square floating plate 15, the floating island is provided with a plurality of planting holes 17, the planting holes 17 are used to place a planting basket 32, and the planting basket 32 ​​is planted with emergent plants 19; the floating island is formed by modularly splicing a plurality of polygonal floating plates, the size of which can be flexibly adjusted according to the water area, and the porous structure provides extension space for the plant roots, thereby enhancing the stability of the floating bed; the planting basket 32 ​​cooperates with the detachable characteristics of the splicing structure of the floating plates to realize local repair and replacement of damaged modules; the emergent plants 19 (such as hydrangea, cattail and variegated reed) in the planting basket 32 ​​are directly in contact with the roots through the roots. The water body has an absorption efficiency of 2 to 4 g / m·d for nitrogen and phosphorus. The anoxic environment formed by the floating island slow flow area (flow rate ≤ 0.1 m / s) promotes denitrification, and the ammonia nitrogen removal rate is increased to 60% to 75%. The allelopathic substances (such as phenolic acid compounds) secreted by the emergent plants 19 inhibit the growth of cyanobacteria and reduce the chlorophyll a concentration of the water body by 30% to 50%. The component achieves a synergistic effect of water purification, ecological restoration and biological shelter. On the one hand, the tall emergent plants 19 have a large coverage area, increase the greening rate, and at the same time provide a certain hiding place for birds living in the pole assembly 7. On the other hand, the tall emergent plants 19 have a relatively developed root system, which can provide a certain living shelter for phytoplankton, zooplankton and fish.

[0052] Preferably, if Figure 1As shown, the juvenile fish protection isolation protection net assembly 2 includes: a reinforcing rib main body 4, to which an isolation protection net 5 is connected, and the aperture of the isolation protection net 5 gradually decreases from top to bottom; the aperture of the isolation protection net 5 gradually decreases from top to bottom, and is used in conjunction with the aquatic plant floating bed assembly 1 and the benthic fish reef assembly 3 to achieve a semi-enclosed structure, thereby increasing the protected activity space for juvenile fish and satisfying the survival of different types of fish; through the gradient change of the large aperture of the upper layer and the small aperture of the lower layer of the isolation protection net 5, juvenile fish are allowed to move freely in the upper layer, while blocking adult fish from entering the isolation area, reducing the risk of juvenile fish being preyed on or mechanically damaged, and the reinforcing rib main body 4 provides rigid support for the isolation protection net 5 to resist water flow impact and extrusion and deformation of adult fish; the isolation protection net 5 and the reinforcing rib main body 4 are designed with flexible nylon to prevent the net from being torn when impacted by wind and waves or fish schools.

[0053] Preferably, if Figure 1 As shown, the reinforcing rib body 4 adopts a nylon rope with a diameter of 0.5 to 1.5 cm, and the diameter of the reinforcing rib body 4 is preferably a nylon rope of 0.5 cm, 1 cm and 1.5 cm. Due to space limitations and for the sake of simplicity, the present invention no longer exhaustively lists the specific point values ​​included in the range. The isolation protection net 5 adopts a high-strength nylon rope with a diameter of 1 cm as a reinforcing rib, which serves as the force-bearing body of the entire isolation protection net, thereby improving the strength and stability of the young fish protection isolation protection net assembly 2. The isolation protection net 5 is woven with a nylon rope with a diameter of 4 to 6 mm, and the diameter of the isolation protection net 5 is preferably woven with a nylon rope of 4 mm, 5 mm and 6 mm, and the diameter of the woven nylon rope is preferably 5 mm to prevent the net line from being too thin to cause damage to the fish school.

At the same time, the isolation protection net 5, the aquatic plant floating bed assembly 1 and the benthic fish reef assembly 3 form a closed system, which can provide a place for benthic animals to attach and a crawling channel from bottom to top.

[0055] Preferably, if Figure 8-11As shown, the benthic fish reef assembly 3 includes: a highly permeable concrete fish reef body, a funnel-shaped through hole 36 is provided on the surface of the highly permeable concrete fish reef body, and the interior of the highly permeable concrete fish reef body is filled with slow-release carbon source particles 37; the interior of the highly permeable concrete fish reef body can help young fish live, and the design of the funnel-shaped through hole 36 makes the through hole 36 present a wide upper and narrow lower shape, which not only accelerates water flow exchange through the Bernoulli effect, increases the dissolved oxygen content inside and outside the fish reef, but also prevents big fish from preying on small fish; the interior of the highly permeable concrete fish reef body is filled with slow-release carbon source particles 37, and the slow-release carbon source particles 37 slowly release organic carbon, provide electron donors for denitrifying bacteria, and improve the nitrate nitrogen removal rate.

The outer highly permeable concrete fish reef body 35 is spliced ​​with the central highly permeable concrete fish reef body 33 to form a closed juvenile fish activity channel. The funnel-shaped through hole 36 is provided The design prevents big fish from entering and preying on small fish, while allowing young fish to move freely, thereby improving the survival rate of young fish. The spliced ​​corners of the highly permeable concrete fish reef body 35 are closed and connected by hard baffles 34. The hard baffles 34 close the corners to eliminate the impact of water vortex on young fish in the channel and maintain a stable flow rate in the channel. The highly permeable concrete material (permeability coefficient ≥1.5cm / s) of the highly permeable concrete fish reef body promotes the exchange of water inside and outside the channel, so that the dissolved oxygen concentration gradient difference is ≤0.5mg / L, ensuring that the dissolved oxygen content in the young fish activity area is stable at 6-8mg / L.

[0062] The modular multi-habitat ecological habitat system consists of six parts, namely, an aquatic plant floating bed component 1, a juvenile fish protection isolation protection net component 2, a benthic fish reef component 3, a bird habitat pole component 7, a water circulation component and an energy auxiliary component. These components can be combined according to different scenarios to form a comprehensive aquatic habitat system.

[0063] The embodiment of the present invention is a sewage plant tailwater wetland treatment. A modular polyhabitat ecological habitat system is set for every 2,000 square meters of water surface. The total project area is 11,000 square meters, and 5 modular polyhabitat ecological habitat systems are set.

[0064] The aquatic plant floating bed component 1 is composed of a square floating plate 15 made of HDPE material. A single square floating plate 15 is 60 cm long and wide, 3 mm thick and has reinforcing ribs. Twelve square floating plates 15 form a row, and a total of 6 rows of floating beds and 6 hexagonal floating plates 14 constitute a closed hexagonal floating island 18. The surface of the floating island 18 has a planting hole 17 with a diameter of 20 cm, and emergent plants such as lily, cattail and variegated reed are planted, eventually forming a hexagonal floating plant circle with open water in the middle; the floating island 18 is fixed on the benthic fish reef component 3 through an isolation protection net 5, and the isolation protection net 5 has a certain degree of elasticity to ensure that the floating island 18 can change with the water level.

The isolation protection net 5 is fixed on the reinforcement rib body 4. The water depth of this implementation is 1.5m, and the height of the isolation protection net 5 is 1.5m;

[0067] The highly permeable concrete fish reef body is cast in one piece by highly permeable concrete. The rough surface can enrich certain microorganisms. The overall shape is U-shaped. The central highly permeable concrete fish reef body 33 is laid inverted to form a closed cubic space with the bottom of the water. A single highly permeable concrete fish reef body is 1.8m long, 0.6m wide, 0.6m high, and 0.1m thick. Inside a single highly permeable concrete fish reef body is an activity space of 1.6x0.4x0.5m, and the interior is laid with slow-release carbon source particles with a particle size of 1cm. The slow-release carbon source particles are made by burning straw and scraps. The opening holes 36 on the facade of the highly permeable concrete fish reef body are funnel-shaped, with an external aperture of 6cm and an internal aperture of 3cm. There are 36 rows of opening holes on the top of the highly permeable concrete fish reef body, and 362 rows of opening holes on the side of the highly permeable concrete fish reef body, and the spacing between the two rows of opening holes 36 is 5cm. Multiple peripheral high-permeable concrete fish reef bodies 35 are spliced ​​to enclose a hexagonal juvenile fish activity channel around the central high-permeable concrete fish reef body 33 according to the shape of the aquatic plant floating bed assembly 1. The multiple peripheral high-permeable concrete fish reef bodies 35 are closed at the corners with hard baffles 34 to ensure that the fish reef channel is closed. This embodiment adopts dry water operation, so the high-permeable concrete fish reef body is assembled at the selected location, which is a water operation. The installation position is determined and accurately installed using an underwater positioning system. It can also be installed by hoisting through onshore assembly.

The energy auxiliary component includes: a photovoltaic panel 23, which is connected to the outside of the floating island. The photovoltaic panel 23 is connected to the submersible pump 25 through a submersible pump transmission line 24. The submersible pump 25 is connected to the counterweight water suction head 26 through a hose (not shown). A controller (not shown) is electrically connected to the submersible pump 25 for controlling the working state of the submersible pump 25. The second electrically driven rotator 30 drives the porous water outlet nozzle 29 to rotate 30° left and right. The controller (not shown) controls the submersible pump 25 to work. The counterweight water suction head 26 absorbs water from the bottom of the water and sprays it through the porous nozzle 29. The electric energy required by the submersible pump 25, the first electrically driven rotator 10 and the second electrically driven rotator 30 is provided by the photovoltaic panel 23 fixed around the floating island 18.

[0069] After the implementation of this embodiment, it played an important role in the restoration of the ecosystem of the tailwater wetland. The survival rate of the young fish such as sand snakehead, flower bone fish, and minnow released in the embodiment reached 80%. It provides certain help for the protection of native wild fish. During the peak period, the number of birds living on the poles reached 40 times / day, including some protective birds. With the help of emergent plants and other artificial auxiliary means, the total nitrogen removal rate of the wetland is also higher than that of traditional wetlands, and the total nitrogen in the effluent is less than 3mg / L. Since the nylon rope of the isolation protection net is thick, no fish is trapped, so the safety of the present invention is guaranteed.
