Description

Technical Field

[0001] The invention relates to a wind and wave resistant flexible enclosure suitable for use in a lake reservoir regulation and purification system, in particular to lake area purification, water body separation, wind and wave resistance, and belongs to the technical field of water ecological restoration. Background Art

[0002] When carrying out lake ecological management work in relatively closed waters, fences are used as common separation and interception devices. They are often used to separate water bodies, reduce wind and waves, block algae and suspended matter, and protect aquatic plants, creating conditions for ecological engineering.

[0003] Ecological restoration projects carried out at home and abroad are mostly focused on cutting off exogenous pollution, dredging sediments, building artificial wetlands, cultivating aquatic vegetation, and biological control. The use of ecological enclosure systems can not only form ecological storage ponds in lakes and reservoirs, but also form a relatively closed water body in the treatment area, preventing the spread of aquatic animals, phytoplankton, upstream garbage and debris, and large-size particles, without affecting water exchange and normal water flow in rivers, creating conditions for carrying out ecological restoration in water areas and achieving the effect of water restoration and ecological purification.

[0004] At present, several common types of enclosures in China include: polyethylene film enclosures, fiberglass enclosures, polyvinyl chloride (PVC) enclosures, waterproof canvas enclosures and cement walls / piles, etc. The physical isolation zone is mainly composed of bamboo piles, polyethylene film, foam plastic tubular buoys floating on the water surface and submerged gabions. However, due to the poor resistance in areas with strong winds and high waves, it is easy to be damaged due to poor resistance, and wind and waves can easily cause erosion and damage to the coast and buildings. To solve these problems, the construction of ecological enclosures is a direction that needs to be studied urgently. Summary of the invention

[0009] Furthermore, the inner enclosure cloth is a water-permeable enclosure cloth made of double-layer PVC water-permeable cloth, and its penetration pore size needs to be less than 0.2mm. Algaecides or activated carbon and other purification substances are added between the double-layer enclosures, and they are sewn with ropes every 5m to form an integrated enclosure.

[0010] Furthermore, the fixed piles are arranged at a position 2m away from both sides of the main enclosure, the depth of the fixed piles inserted into the bottom mud is not less than 0.5m, and are fixed on both sides of the buoy-type breakwater with figure-eight or cross ropes. The ropes are made of nylon material, and the ratio of the inner fixing rope to the water surface height is 2:1. The outer fixing rope is vertically stretched, and after fixing, the enclosure forms an angle of 60° with the ground.

[0011] Furthermore, the gabion is connected to the bottom edge of the enclosure by an iron buckle or a wire rope, and the gabion is completely buried in the bottom mud.

[0012] Furthermore, the buoy-type breakwater is directly formed by high-density polyethylene material, namely, HDPE, and is filled with porous foam and activated carbon inside.

[0013] Furthermore, the buoy-type breakwater is a buoy in the shape of a circular tube with a diameter of 30 cm. There are two rows of through holes distributed on the buoy, with no less than 8 through holes in each row, a hole diameter of 2 cm, and a ratio of the number of holes to the enclosure length (m) of 8:1; the buoy is connected to the main enclosure by plywood or hot welding.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] like Figure 1 As shown, the wind and wave resistant flexible enclosure mainly includes three parts, a buoy-type breakwater 3, an impermeable enclosure 10, a permeable enclosure 11, and a fixing device. The buoy-type breakwater is connected to the PVC permeable enclosure from top to bottom, and the fixing device is composed of a fixing rope, a fixing pile and a gabion. The permeable enclosure and the perforated breakwater are used to achieve lake purification and wave elimination.

[0024] A wind and wave resistant flexible enclosure suitable for use in a lake storage and purification system needs to include at least a fixing device and a main enclosure. The present invention includes a main enclosure 1 and a counterweight gabion 2 fixedly connected to the bottom. The gabion 2 is connected to the bottom of the enclosure and buried in the bottom mud. It also includes a buoy-type breakwater 3 that can break waves and break waves, a fixing pile 4 that plays a fixing role, and a fixing rope 5, which is connected to the fixing rope through the fixing pile to fix the enclosure. The enclosure cloth of the inner enclosure is a permeable enclosure cloth using a double-layer PVC permeable cloth, and its penetration aperture must be less than 0.2mm. Purification substances such as coagulants or activated carbon 7 are added between the double-layer enclosures, and they are sewn with ropes every 5m to form an integrated enclosure.

[0025] As an embodiment, the buoy-type breakwater is a buoy in the shape of a circular tube with a diameter of 30 cm. Two rows of through holes 6 are distributed on the buoy, each row has no less than 8 through holes, the hole diameter is 2 cm, and the ratio of the number of holes to the enclosure length (m) is 8:1; the buoy is connected to the main enclosure by plywood or hot welding.

[0026] As an example, the buoy-type breakwater is circular, the buoy is customized with high-density polyethylene material, and is filled with sponge and activated carbon. The diameter of the buoy is 30 cm, and holes are directly punched on the buoy, with two rows of through holes 6 distributed in parallel up and down. There are no less than 8 holes in one row, and the ratio of the number of holes to the length of the enclosure (m) is 8:1. The diameter of the through hole is 2 cm; the buoy is connected to the lower enclosure by a splint or hot welding.

[0027] As an embodiment, the soft main body enclosure is made of polyvinyl chloride material, and the top end of the enclosure is tightly connected to the perforated buoy-type breakwater by heat welding or sewing.

[0028] Preferably, the wind and wave resistant flexible enclosure adopts double-layer PVC permeable cloth, the penetration pore size of which needs to be less than 0.2mm to ensure that it will not be damaged by the impact of wind and waves and can play a role in filtering and purifying water.

[0029] Preferably, the wind and wave resistant flexible enclosure is placed obliquely in the lake, i.e., forms an angle of 60° with the ground, to prevent the enclosure from being crushed by excessive wind and waves or water entering the lake when placed vertically.

[0030] Splints and ropes are used for stitching every 5m to facilitate replacement of the enclosure, forming an integrated enclosure that not only prevents impact from wind and waves, but also effectively blocks pollutants from open waters from entering the enclosure water body.

[0031] As an embodiment, the fixing device is provided with fixed piles at a distance of 2m from both ends of the enclosure, and the fixing piles must be inserted into the bottom mud to a depth of not less than 0.5m.

[0032] Use fixing ropes to fix at both ends of the buoy in a figure-eight or cross shape. The ratio of the inner fixing rope to the water surface is 2:1, and the outer fixing rope is straight. The fixing rope is made of nylon material and is connected to the top of the enclosure with a rope.

[0033] As an embodiment, the gabions in the fixing device are also connected to the bottom curled edges of the enclosures through iron buckles and ropes, and the gabions must be completely buried in the bottom mud to prevent the enclosures from moving under the action of wind and waves.

[0034] As an embodiment, the wind and wave resistant flexible enclosure forms an angle of 60° with the ground. The enclosure is designed with a two-layer integrated enclosure belt of semi-arc or semi-frame type. The inner main enclosure material is a double-layer water-permeable PVC enclosure. The double-layer water-permeable enclosure is sewn together with ropes, and large-particle concrete is added in between. The particle size is greater than 0.2mm to filter the water. The outer layer is two layers of impermeable cloth to form an opening. The size and direction of the opening can be adjusted according to the actual situation of the lake flow, which facilitates water exchange while intercepting pollutants, and has a diversion effect so as to be able to withstand greater wind and wave impact.

[0035] As an embodiment, the size of the wind and wave resistant enclosure can be controlled according to the specific implementation case, and a permeable mesh with adjustable size can be set to make corresponding adjustments according to different water volume scenarios, i.e., large water volume and small water volume; a flushing device can also be added to the top of the enclosure to flush the enclosure regularly to prevent clogging of the enclosure.

[0036] As an embodiment, an aeration system 13 and a dosing device are added between the open enclosure 10 and the double-layer permeable enclosure 11 to increase the water dynamics and dissolved oxygen content, and bactericides and algaecides and natural mineral powder flocculants are added to the water body. The added agents have no toxic effect on aquatic organisms and will not cause pollution.

[0037] As an embodiment, an artificial wetland 12 or a water purification device is provided inside the permeable enclosure 11, which can achieve multiple water purifications during lake and reservoir regulation.

[0038] The working principle and usage process are as follows:

[0039] Arrange the wind and wave resistant flexible enclosure in the lake or reservoir where it is needed, adjust the enclosure depth and the suspension effect of the buoy-type breakwater according to the water depth of the lake or reservoir, and add the opening direction of the outer impermeable enclosure according to the direction of water flow. When rainwater enters the lake or reservoir, it first enters the permeable enclosure for storage, then reacts with activated carbon or flocculants in the permeable enclosure for purification, and then slowly enters the open enclosure, determines the opening direction according to the direction of water flow, and enters the lake or reservoir. Among them, the aeration system and dosing device between the open enclosure and the permeable enclosure can effectively avoid the impact of blue algae on water quality and the blockage of the device. It should be noted that the fixed setting should be tightly connected to the enclosure while ensuring flexibility to avoid enclosure damage and detachment; the number of openings in the buoy-type breakwater should be appropriately adjusted according to the length of the lake or reservoir without affecting the enclosure effect.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.

[0041] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
