Description

Technical Field

[0001] The utility model relates to the technical field of floating wetlands, in particular to a water-based composite floating wetland for the habitat of avian swimming birds. Background Art

[0002] An artificial wetland is a ground similar to a marshland that is artificially constructed and controlled. Sewage and sludge are controlled and distributed onto the artificially constructed wetland. During the process of flowing in a certain direction, the sewage and sludge mainly utilize the triple synergistic effects of soil, artificial fillers, plants, and microorganisms to treat the sewage. Its mechanism of action includes adsorption, retention, filtration, redox, precipitation, microbial decomposition, transformation, etc. The artificial wetland treatment system has the characteristics of large buffer capacity, good treatment effect, simple process, low investment, and low operating cost, and is an ecological sewage treatment process with broad application prospects.

[0003] Currently, the protection of water resources mainly focuses on ecological protection and sewage treatment. The current treatment plan for combining the two is to build artificial wetlands. In view of the need for the restoration of farmland during the construction of artificial wetlands and the consideration of minimizing the damage to the structure of artificial wetlands and ensuring operating conditions after restoration, it is necessary to use a composite floating wetland for crop planting. However, the current development of composite floating wetlands is still in its infancy and cannot be reasonably adapted to the complexity of the artificial wetland environment. For example, the utility model patent with the publication number CN208916915U provides a composite fiber unit module and a floating wetland including the same. The composite fiber unit module includes a first high-molecular fiber layer located at the top layer, a second high-molecular fiber layer located at the bottom layer, and a plant fiber layer located between the first high-molecular fiber layer and the second high-molecular fiber layer. The first high-molecular fiber layer and the plant fiber layer are provided with planting holes, and plants are planted in the planting holes. The side surface of the composite fiber unit module has through holes, and steel strands are passed through the through holes to tightly connect and fix the composite fiber unit modules together to form a floating wetland. However, the above structure also has some technical defects. First, the steel strands are passed through the through holes to connect multiple composite fiber unit modules together. Since the steel strands are relatively thin, the composite fiber units will become heavier after planting plants, which easily causes the steel strands to cut through the holes. In addition, the growth rates of plants vary, which easily leads to inconsistent weights borne by each composite fiber unit and is prone to collapse. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the utility model provides a water-based composite floating wetland for the habitat of avian swimming birds, which solves the problem of easy collapse of the floating wetland proposed in the above background art.

[0005] To achieve the above object, the utility model provides the following technical solution: A composite floating wetland for waterfowl birds to inhabit on water, comprising floating wetland units and connectors. A number of floating wetland units are combined together through the connectors. The floating wetland unit is composed of an upper fiber layer, a lower fiber layer, and a plant fiber layer arranged between the upper fiber layer and the lower fiber layer. Planting holes are formed on the upper fiber layer. A horizontally penetrating transverse connection hole is formed on the upper fiber layer. A vertically penetrating vertical connection hole is formed on the lower fiber layer. The transverse connection hole and the vertical connection hole are arranged in a perpendicular direction. The connector includes a sleeve, a steel pipe, and a steel wire. The sleeve is a circular pipe made of plastic material. The sleeve is embedded into the transverse connection hole and the vertical connection hole. The steel pipe is embedded into the sleeve. The steel wire passes through the steel pipe to connect and fix the floating wetland units together.

[0006] Further, two transverse connection holes and two vertical connection holes are formed on each floating wetland unit.

[0007] Further, multiple planting holes can be evenly distributed on the floating wetland unit in the form of a matrix. The depth of the planting hole is 8 - 11 cm.

[0008] Further, the steel pipe includes a first steel pipe and a second steel pipe. A welding gasket is arranged at one end face position of the first steel pipe. The first steel pipe is inserted into the sleeve of the floating wetland unit, and the welding gasket is exposed on the outer wall of the floating wetland unit. A protruding retaining piece is arranged in the middle of the second steel pipe. Two ends of the second steel pipe are respectively inserted into the connection holes of two adjacent floating wetland units to connect the two floating wetland units together.

[0009] Further, the length of the first steel pipe inserted into the sleeve of the floating wetland unit is at most two-thirds of the length or width of the floating wetland unit.

[0010] Further, the length of the second steel pipe inserted into the connection hole is at least one-third of the length or width of the floating wetland unit.

[0011] Further, the upper fiber layer, the lower fiber layer, and the plant fiber layer can be bonded through an adhesive.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] In the utility model, a number of floating wetland units are connected into a whole through the steel pipe. A firm overall structure is formed by the support of the steel pipe between multiple floating wetland units. Therefore, it has a large and uniform supporting force. During use, the situation of collapse or deformation due to local overweight will not occur. Compared with the traditional steel wire connection method, its service life and use effect are greatly improved. Description of the Drawings

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figure 1 and Figure 2 , a composite floating wetland for waterfowl habitats of birds, comprising a floating wetland unit 1 and a connector 2, and a plurality of floating wetland units 1 are combined together through the connector 2.

[0022] The floating wetland unit 1 is composed of an upper fiber layer 11, a lower fiber layer 12, and a plant fiber layer 13 disposed between the upper fiber layer 11 and the lower fiber layer 12. Both the upper fiber layer 11 and the lower fiber layer 12 are made of high molecular polyester fiber resin, and the plant fiber layer 13 is made of natural plant fiber materials. The natural plant fibers slowly decompose in the water body, providing a certain amount of carbon source for the plants on the composite fiber floating wetland. The upper fiber layer 11, the lower fiber layer 12, and the plant fiber layer 13 can be bonded through an adhesive. The thickness of the upper fiber layer 11 and the lower fiber layer 12 is 4 - 6 cm. The thicker the thickness, the greater the buoyancy generated. When both the upper fiber layer 11 and the lower fiber layer 12 are 5 cm thick, a floating wetland unit 1 can generate a buoyancy of more than 60 kg, and its buoyancy is sufficient to plant all aquatic plants, some trees and shrubs. The thickness of the plant fiber layer 13 is 8 - 10 cm. A horizontally penetrating transverse connection hole 15 is formed in the upper fiber layer 11, and a vertically penetrating vertical connection hole 16 is formed in the lower fiber layer 12. The transverse connection hole 15 and the vertical connection hole 16 are arranged in a vertical direction, and the transverse connection hole 15 and the vertical connection hole 16 are used for installing the connecting member 2. Preferably, two transverse connection holes 15 and two vertical connection holes 16 are formed in each floating wetland unit 1.

[0023] Planting holes 14 are formed in the upper fiber layer 11, and the planting holes 14 are used for planting plants. The planting part includes the planted plant 3 and its root system 5. A surface planting soil layer is laid on the top surface of the upper fiber layer 11, and land plants can be planted.

[0024] The number of the planting holes 14 can be determined according to the size of the floating wetland unit 1 and the types of the planted plants. Multiple planting holes 14 can be evenly distributed on the floating wetland unit 1 in a matrix form. The depth of the planting holes 14 is 8 - 11 cm, and each planting hole 14 can plant 1 planted plant, and the planted plants can be selected from one or more aquatic or terrestrial plants.

[0025] The floating wetland unit 1 provided by the present utility model can be of any shape, such as square, rectangular, circular, oval, etc. In this embodiment, the composite floating wetland is of a cuboid structure.

[0026] Please refer to Figure 3 、 Figure 4, the connecting member 2 includes a sleeve 21, a steel pipe 22 and a steel wire 23. The sleeve 21 is a circular pipe made of plastic material. The sleeve 21 is embedded in the horizontal connection hole 15 and the vertical connection hole 16, and the sleeve 21 is in close contact with the inner walls of the horizontal connection hole 15 and the vertical connection hole 16, so that the sleeve 21 is fixed in the connection hole; the steel wire 23 passes through the steel pipe 22, and the steel wire 23 passes through the steel pipe 22 to tightly connect and fix the floating wetland units 1 together. Stainless steel buckles are provided at both ends of the steel wire 23; the steel pipe 22 is embedded in the sleeve 21, and the steel pipe 22 is used to increase the strength of the floating wetland unit 1. The steel pipe 22 includes a first steel pipe 221 and a second steel pipe 222. A welding gasket 223 is provided at one end face of the first steel pipe 221. The welding gasket 223 is used to be welded with the welding gasket 223 of another first steel pipe 221 into a whole to realize the connection between the two. The first steel pipe 221 is inserted into the sleeve 21 of the floating wetland unit 1, and the welding gasket 223 is exposed on the outer wall of the floating wetland unit 1 for convenient welding; preferably, the length of the first steel pipe 221 inserted into the sleeve 21 of the floating wetland unit 1 is at most two-thirds of the length or width of the floating wetland unit 1; a raised stop piece 224 is provided in the middle of the second steel pipe 222. The two ends of the second steel pipe 222 are respectively inserted into the connection holes of two adjacent floating wetland units 1, so as to connect the two floating wetland units 1 together. Taking the stop piece 224 as a blocking point, the length of the second steel pipe 222 inserted into the connection hole is at least one-third of the length or width of the floating wetland unit 1.

[0027] Taking the connection of two floating wetland units 1 as an example, the specific connection method of connecting two floating wetland units 1 by using steel pipes is described as follows: As Figure 5 shown, first insert the first steel pipe 221 into a horizontal connection hole 15 of the upper fiber layer 11 of a floating wetland unit 1 from one end. The welding gasket 223 of the first steel pipe 221 abuts against the opening of the horizontal connection hole 15, and then insert the second steel pipe 222 from the other end of the horizontal connection hole 15. The stop piece 224 abuts against the opening of the horizontal connection hole 15. At this time, the ends of the first steel pipe 221 and the second steel pipe 222 just touch; then insert the second steel pipe 222 into a horizontal connection hole 15 of the upper fiber layer 11 of a floating wetland unit 1 from one end, and then insert the first steel pipe 221 from the other end of the horizontal connection hole 15; then insert the first steel pipe 221 and the second steel pipe 222 into the vertical connection hole 16 in this way. Finally, weld the two adjacent welding gaskets 223 on the two floating wetland units 1 together. Finally, pass the steel wire 23 through the steel pipe 22 and lock it to complete the assembly. The effect after assembling multiple floating wetland units 1 is as Figure 6 shown. After assembling multiple floating wetland units 1, since they support each other through steel pipes to form a solid overall structure, they have a large and uniform supporting force, and the situation of collapse or deformation due to local overweight will not occur.

[0028] The floating wetland unit 1 is designed to float on the water surface at a certain position and change with the water level change, and it can be fixed by the heavy object fixing method. For example, the steel wire 23 is connected between the positioning stone 4 and the floating wetland unit 1, and the weight quantity of the positioning stone 4 can be increased according to the hydraulic conditions to enhance the impact resistance.

[0029] The surface part of the floating wetland unit 1 can provide a stable habitat for amphibians and birds. The roots of the underwater part of the floating wetland unit 1 provide sufficient living conditions for microorganisms and a safe living environment for organisms such as fish and shrimps.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
