Description

Technical Field

[0001] This utility model relates to the field of bio-curtain technology, and more specifically to a bio-curtain used for ecological interception in river channels. Background Technology

[0002] Bio-curtains refer to strip-shaped packing materials made of high-molecular polyester nanomaterials. They have extremely high adsorption and biocompatibility, enabling them to adsorb a large number of microbial communities and form an attached active biofilm. The microbial communities on the bio-curtains degrade organic pollutants and nitrogen and phosphorus in the water, and also intercept suspended solids in the water, thereby comprehensively improving water quality. At the same time, bio-curtains can provide habitats for fish and shrimp, promoting the restoration of local aquatic biodiversity.

[0003] Currently, biological curtains are mostly installed in the upper reaches of rivers. Due to the faster water flow in the upper reaches, the lower end of the biological curtain will tilt at a large angle and float in the water under the influence of the water flow, which will greatly reduce the interception effect of the biological curtain. Therefore, this needs to be improved. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a biological curtain for ecological interception in river channels. By setting weights to pull the biological curtain, it can be ensured that the biological curtain can still hang down in waters with fast flow, so as to ensure the ecological interception effect.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A bio-curtain for ecological interception in river channels, comprising:

[0007] The curtain frame has multiple connection points along its length;

[0008] A curtain belt, the curtain belt comprising a strip and a pile tissue arranged circumferentially around the strip, one end of the strip being connected to a connecting position;

[0009] A weight block is attached to the end of the strip away from the connection point.

[0010] As a further improvement of this utility model, the curtain frame forms a groove at the corresponding connection position.

[0011] As a further improvement of this utility model, one end of the strip is bound to the groove.

[0012] As a further improvement of this utility model, the weight is in the shape of a hollow sphere, and water-permeable holes are arranged on the surface of the weight. A connecting part extends outward from the weight, and a through hole is provided on the connecting part and connected to one end of the strip through the through hole.

[0013] As a further improvement of this utility model, the curtain frame includes a plurality of rods connected in sequence, and adjacent rods are detachable.

[0014] As a further improvement of this utility model, the rod has a insertion hole along its length, one end of the rod extends outward to form a plug-in portion, and the other end is symmetrically provided with a stop block, which is used to abut against the end of another rod to form a groove.

[0015] As a further improvement of this utility model, the plug-in part is provided with a first positioning hole, and the end of the rod away from the plug-in part is provided with a second positioning hole that cooperates with the first positioning hole.

[0016] As a further improvement of this utility model, the rod is made of a floating material, and a floating component is provided in the insertion hole.

[0017] As a further improvement of this utility model, adjacent villous tissues are aligned with each other.

[0018] The beneficial effects of this utility model are: by setting up the weight, the curtain belt can be pulled in the water, thereby reducing the tilting of the curtain belt caused by the water flow, ensuring the curtain belt hangs in the water, and improving the ecological interception effect.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals.

[0024] like Figure 1-3As shown, a biological curtain for ecological interception in rivers includes a curtain frame 1, curtain strips 2, and weights 4. The curtain frame 1 has multiple connecting positions along its length, and grooves 5 are formed at the corresponding connecting positions. The curtain strips 2 are connected to the connecting positions and the weights 4 at both ends. In the river, the curtain strips 2 hang naturally in still or slow-flowing conditions. When the water flow in the river accelerates, the curtain strips 2 tilt under the influence of the water flow and are pulled by the weights 4 to significantly reduce the tilt angle, thereby increasing the droop of the curtain strips 2. This ensures the interception and purification effect even when the flow rate increases. There are multiple curtain strips 2 arranged along the length of the curtain frame 1. The curtain frame 1 is made of a floating material and is connected to the banks at both ends during use to confine the curtain frame 1 to the water. Specifically, ropes can be connected to both ends of the curtain frame 1, with one end of the rope connected to the bank to restrict the position of the curtain frame 1.

[0025] The curtain frame 1 includes multiple rods 9 connected in one go. Adjacent rods 9 are detachable. The number of rods 9 is not specifically limited. Operators can select an appropriate number of rods 9 to connect according to the specific width between different river channels. Each rod 9 forms a socket 10 along its length. One end of the rod 9 extends outward to form a plug-in part 11, and the other end is symmetrically provided with a stop 12. The plug-in part 11 is used to plug into the end of another rod 9 corresponding to the stop 12. In one embodiment, the plug-in part 11 is threadedly connected to the end of another rod 9. In this embodiment, the plug-in part 11 and the other rod 9 are threadedly connected. The ends are in a sliding fit to facilitate installation and disassembly. The outer wall of the plug part 11 is provided with a first positioning hole 13, and the other end of the rod 9 is provided with a second positioning hole 14 corresponding to the first positioning hole 13. When the plug part 11 is inserted into the plug hole 10, the first positioning hole 13 and the second positioning hole 14 correspond to each other. In one way, the operator can connect the plug part 11 and the rod 9 by connecting the first positioning hole 13 and the second positioning hole 14 with a bolt thread. In this embodiment, the first positioning hole 13 and the second positioning hole 14 are connected by a pin fit.

[0026] Furthermore, after the insertion part 11 is inserted into the insertion hole 10, the stop block 12 can abut against the end face of the rod 9, thereby forming two symmetrically arranged arc-shaped grooves between the two rods 9. The two arc-shaped grooves together form the groove part 5. During use, one end of the curtain belt 2 is tied in the groove part 5, so that the groove part 5 limits the curtain belt 2 to prevent the curtain belt 2 from shifting during long-term use.

[0027] Furthermore, in order to ensure the buoyancy of the curtain frame 1 during use and to prevent the curtain frame 1 from sinking due to the attachment of garbage on the river, a floating component 15 is provided inside the curtain frame 1 to enhance the buoyancy of the curtain frame 1. The floating component 15 is specifically a columnar foam plastic to reduce the production cost. Alternatively, any other existing floating material can be used.

[0028] Preferably, the cross-section of the curtain frame 1 is circular. In other cases, it can also be set as a triangle or other regular or irregular shapes.

[0029] Preferably, the groove 5 also includes an annular groove arranged along the length direction on the curtain frame 1. By setting the annular groove, the number of curtain strips 2 can be increased to improve the interception and purification effect.

[0030] In this embodiment, the curtain strip 2 is made of high molecular polyester nanoparticles to obtain good adsorption and biocompatibility. The curtain strip 2 includes a strip located in the center and a pile tissue 3 arranged around the strip in a circumferential manner. One end of the strip is tied to the groove 5.

[0031] In order to maximize the ecological interception effect of the curtain strip 2, in this embodiment, adjacent villous tissues 3 are aligned with each other. In another embodiment, the adjacent villous tissues 3 can also be set to be spaced apart or partially overlapped.

[0032] Furthermore, in this embodiment, in order to reduce the impact of water flow, the weight 4 is spherical and hollow, and water-permeable holes 6 are arranged on the surface of the weight 4 to allow water to flow through.

[0033] Preferably, in order to ensure the traction effect of the weight 4 itself, in one embodiment, an iron ball is movably installed inside the hollow weight 4 to greatly improve the traction effect of the weight 4, while also ensuring the passage of water.

[0034] Furthermore, the surface of the weight 4 extends outward to form a connecting part 7, and the connecting part 7 is provided with a through hole 8, and one end of the strip is tied to the through hole 8.

[0035] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
