Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of scouring bottom protection device, especially relates to a marine wind power large diameter single pile scouring bottom protection device based on waste tyre. BACKGROUND

[0002] Wind power generation refers to the green technology of converting the kinetic energy of wind into electric energy. As an environmentally friendly energy, it is not only pollution-free and harmless, but also renewable.

[0003] In order to widely benefit and efficiently use electric power resources, large diameter single pile foundation stands out with its unique advantages and becomes a solid backer of offshore wind power station. The large diameter single pile foundation is composed of a thick steel pipe pile, which can not only stably bear huge horizontal and vertical load, but also has excellent fatigue resistance, ensuring the stable, safe and efficient operation of wind turbine in the sea.

[0004] However, seawater scouring foundation brings potential threat. The corrosive nature of seawater can erode the foundation structure, and the generation of vortex can sweep away the silt around the foundation, which will challenge the long-term stable operation of offshore wind power station. SUMMARY

[0005] The utility model wants to solve the technical problem of providing a marine wind power large diameter single pile scouring bottom protection device based on waste tyre with simple structure, economic and environmental protection, and significant scouring effect.

[0006] To solve the above technical problems, the utility model adopts the following technical scheme:

[0007] The marine wind power large diameter single pile scouring bottom protection device based on waste tyre mainly comprises a waste tyre net, which is connected by connecting ropes; the top side and the bottom side of the tyre bead of the waste tyre are provided with leakproof nets, and the leakproof nets are filled with waste tyre fragments; the connecting rope is composed of a steel wire rope and a plastic corrosion-resistant outer sleeve wrapped outside the steel wire rope.

[0008] The waste tyre net is a mesh structure composed of multiple waste tyres connected by horizontal connecting ropes and vertical connecting ropes.

[0009] The tyre body of the waste tyre is respectively provided with horizontal connecting holes and vertical connecting holes matched with the horizontal connecting ropes and the vertical connecting ropes; the horizontal connecting hole or the vertical connecting hole comprises two connecting holes arranged on the opposite sides of the tyre body.

[0010] The inner side and the outer side of the tyre body at the connecting position of the connecting rope and the tyre body are provided with positioning assemblies.

[0011] The above-mentioned scouring bottom protection device further comprises a foundation and a single pile, and the waste tyre net covers the foundation around the single pile.

[0012] The ends of the transverse and longitudinal connecting ropes are connected to the fixed piles on the foundation.

[0013] The positioning assembly mainly comprises a positioning block and a bolt threadedly mounted on the positioning block; the positioning block is provided with an extrusion hole and a driving hole; an extrusion sliding block is slidably mounted in the extrusion hole and in contact with the transverse connecting rope; a driving sliding block is slidably mounted in the driving hole, and the inclined surface of the driving sliding block is in contact with the inclined surface of the extrusion sliding block; and the bottom end of the bolt is in contact with the driving sliding block.

[0014] In view of the problem that the large-diameter single pile foundation of the offshore wind power is eroded and weakened by seawater, the inventor designs a scour protection device for the large-diameter single pile of offshore wind power based on waste tires, which mainly comprises a waste tire net formed by waste tires connected by connecting ropes; the top side and the bottom side of the tire bead of the waste tire are provided with leakproof nets, and the waste tire fragments are filled between the leakproof nets; the connecting rope is composed of a high-strength steel wire rope and a plastic corrosion-resistant sheath wrapped outside the steel wire rope. The device weaves the waste tire into a net to cover the single pile foundation, which not only effectively slows down the direct scouring of seawater on the foundation by using the waste tire net, but also reduces the transportation of seawater to the silt around the foundation by interfering with and weakening the formation of vortexes through the gaps between the waste tires; the gaps between the waste tires can also naturally accumulate silt, further reinforcing the surface of the foundation and enhancing its stability. In addition, the combination of the leakproof net and the waste tire fragments provides additional protection for the hollow space in the tire bead, further buffering the flow of seawater and inhibiting the scouring of the foundation. Therefore, the scour protection device has the potential for wide application in the field of offshore wind power due to its simple structure, excellent scouring prevention effect and innovative use of waste tires. Its promotion not only ensures the stable operation of the offshore wind power station, but also realizes the resource utilization of waste tires, reflecting the dual value of economic benefit and environmental protection.

DETAILED DESCRIPTION

[0021] As Figures 1 to 5 shown, the offshore wind power large-diameter single pile scouring bottom protection device based on waste and old tires of the utility model innovatively uses the waste and old tire net 200 as the core protection structure, and this unique waste and old tire net 200 closely surrounds and covers the ground 100 around the single pile 101. Among them:

[0022] The waste and old tire net is a net-like structure formed by a plurality of waste and old tires 202 connected with each other through the transverse connecting rope 204 and the longitudinal connecting rope 205; the tire body of the waste and old tire is respectively provided with the transverse connecting hole and the longitudinal connecting hole matched with the transverse connecting rope and the longitudinal connecting rope; the transverse connecting hole or the longitudinal connecting hole comprises two mounting holes 203 arranged on the opposite sides of the tire body; and the end of the transverse connecting rope and the longitudinal connecting rope is connected with the fixed pile 201 on the ground surface. The inner side and the outer side of the tire body at the connecting position of the connecting rope and the tire body are respectively provided with the positioning assembly 300, and the positioning assemblies on both sides accurately clamp and fix the connecting rope, so that the position of the waste and old tire is stable and immovable. The positioning assembly mainly comprises the positioning block 301 and the bolt 306 threadedly mounted thereon; the positioning block is internally designed with the extrusion hole 302 and the driving hole 304, the extrusion sliding block 303 is slidably arranged in the extrusion hole, the extrusion sliding block is in close contact with the transverse connecting rope 204, the driving sliding block 305 is slidably arranged in the driving hole, and the inclined surface of the driving sliding block is in contact with the inclined surface of the extrusion sliding block; the bottom end of the bolt is in contact with the driving sliding block. When the bolt rotates, the bottom end pushes the driving sliding block to slide in the driving hole, and then pushes the extrusion sliding block to slide in the extrusion hole through the action of the inclined surface, so as to realize the extrusion and fixation of the connecting rope.

[0023] The top side and bottom side of the tire bead (i.e. the middle circular part of the tire) of the waste tire are provided with leak-proof nets 208, and the space between the leak-proof nets is filled with waste tire fragments 209. This design not only enhances the anti-erosion capacity of the device, but also helps the accumulation of silt, further consolidating the foundation. The connecting cable is composed of corrosion-resistant steel wire rope 206 and plastic corrosion-resistant outer sleeve 207 wrapped around the steel wire rope. This combination of materials effectively resists the corrosion of seawater on the steel wire rope, ensuring the long-term stability of the connecting cable.
