Description

Technical Field

[0001] The present invention relates to the field of composite material pipes, and specifically to a production method of composite material pipes for water Background Art

[0002] At present, most existing communication poles and power poles are made of cement and metal materials. During use, they have defects such as large mass, high transportation cost, high maintenance cost, and being vulnerable to environmental corrosion. These defects seriously threaten the safe power transmission of distribution poles. Fiber-reinforced composite materials have excellent designability of strength and stiffness, and have advantages such as light weight, corrosion resistance, anti-creep, long life, and little maintenance. They are excellent materials for distribution poles. The main factor restricting the size of high towers is the strength of composite materials. The existing material strength can no longer meet the requirements of large tower equipment.

[0003] The total global ocean area is 361.132 million square kilometers, accounting for 70.8% of the total area of the earth. The area of the offshore sea area with a depth of 500 meters is about 10 million square kilometers, and China is about 800,000 square kilometers. At present, this deep-sea wind power resource has not been developed, and the technical difficulty in development lies in the submarine foundation and support poles of wind turbines. In this project, a floating platform is used to process high-strength composite support poles on-site at the wind turbine, directly buried in the seabed, and made into an integrated design of pole and column. The structure is simple and reasonable, the construction is fast, convenient and concise, the project cost is low, it is not affected by seawater corrosion, there is no problem of large-scale land transportation, and the designed service life is long.

[0004] The existing technology has the following problems:

[0005] 1. Composite material pipes need to first produce prefabricated pipes in the factory, and then transport them from the workshop to the designated location for secondary installation, with low efficiency.

[0006] 2. In some deeper sea areas, there is a high demand for the length of pipe poles. The existing technology cannot directly produce ultra-long poles, and it is also inconvenient to drive piles for ultra-long poles, making it difficult to fix. Summary of the Invention

[0007] In order to solve the problems of the existing technology, the present invention provides a production method of composite material pipes for water, which directly produces composite material pipes on the water surface, integrates production and pile driving to improve production efficiency, and can prepare ultra-long composite material pipes through a segmented preparation method.

[0008] The present invention provides a production line for composite material pipes for water, including a floating structure and a vertical composite material tower production device and a drilling rig device installed on the floating structure. A track is installed on the floating structure, the vertical composite material tower production device is installed at one end of the floating structure, and the drilling rig device is installed on the track and slides along the track at both ends of the floating structure.

[0009] For further improvement, traction devices are respectively arranged at the upper and lower ends of the vertical composite material pole tower production equipment.

[0010] The present invention also provides a method for producing underwater composite material pipes, including the following steps:

[0011] 1) The vertical composite material pole tower production equipment produces a composite material pipe with a through hole in the center from top to bottom. A drill bit is installed at the bottom of the composite material pipe until the bottom of the composite material pipe touches the water bottom.

[0012] 2) The drilling equipment slides to the vertical composite material pole tower production equipment through the track, and controls the drill bit at the bottom of the composite material pipe to drill holes through the through hole in the center of the composite material pipe.

[0013] 3) The composite material pipe is driven into the water bottom along the drilled hole, and concrete is injected into the hole to fix the composite material pipe.

[0014] For further improvement, the composite material pipe is prepared by a segmented preparation method. First, the lower-section composite material pipe is prepared through steps 1) to 3). Then, the mold of the vertical composite material pole tower production equipment is installed reversely, and the upper-section composite material pipe is prepared from bottom to top by the traction device at the upper end. After the upper-section composite material pipe is completed, winding and secondary curing are carried out at the connection of the upper and lower-section composite material pipes to fix the composite material pipe into an integral structure.

[0015] The beneficial effects of the present invention are as follows:

[0016] 1. After producing the composite material pipe on the water surface, the produced composite material pipe is directly driven into the water bottom for fixation, improving the production efficiency.

[0017] 2. Prepared by the segmented preparation method, with the floating platform vertically arranged and the processing column, ultra-long composite material pipes can be prepared by utilizing the ocean depth. The column is an integral one-time forming structure, improving the diversity of application scenarios.

[0018] 3. It can be continuously produced, and by utilizing the buoyancy of seawater, worldwide problems such as material breakage and transportation are solved.

[0019] 4. It can be used to produce pole tower equipment inserted underwater, and can also be used to prepare underwater pile foundations and build water platforms, with wide practicability.

[0020] 5. When used in wind power generation equipment, a pile foundation can be formed by using the composite material pipe first to build a water platform, and then ultra-long wind turbine blades with a length of more than 150 meters can be directly produced and assembled on the platform, solving the production and transportation problems.

[0021] 6. The service life exceeds 50 years, there is no problem of steel corrosion, and no anti-corrosion coating treatment is required. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, rather than all, embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the protection scope of the present invention.

[0027] The present invention provides a waterborne composite material pipe production line, the structure of which is as Figure 1 shown, including a floating body structure 1, a vertical composite material pole production device 2 and a drilling device 3 installed on the floating body structure. A track 4 is installed on the floating body structure. The vertical composite material pole production device is installed at one end of the floating body structure, and the drilling device 3 is installed on the track and slides along the track at both ends of the floating body structure.

[0028] The floating body structure adopted by the present invention can adopt two juxtaposed hulls. A production workshop spanning the two hulls is covered at one end of the hulls. Tracks are directly arranged between the two hulls, and the drilling device slides along the track between the two hulls.

[0029] The vertical composite material pole production device is as Figure 2 shown, including a mold, a winding device 7 and a curing device arranged from top to bottom. Yarn racks, felt racks 6 and corresponding traction devices 5 are distributed around the mold. Traction devices are respectively arranged at the upper and lower ends of the vertical composite material pole production device.

[0030] The present invention also provides a method for producing waterborne composite material pipes, including the following steps:

[0031] 1) The vertical composite material pole tower production equipment produces composite material pipes with through holes in the center from top to bottom. The cross-section of the composite material pipes is as shown in Figure 3 . A drill bit is installed at the bottom of the composite material pipe until the bottom of the composite material pipe touches the water bottom;

[0032] 2) The drilling rig equipment slides to the vertical composite material pole tower production equipment through the track, and controls the drill bit at the bottom of the composite material pipe to drill holes through the through hole in the center of the composite material pipe;

[0033] 3) The composite material pipe is driven into the water bottom along the drilled hole, and concrete is injected into the hole to fix the composite material pipe.

[0034] For some special environments where super-long pile foundation structures are required, since the length of the composite material pipes that the vertical composite material pole tower production equipment can produce is limited, a segmented preparation method can be adopted. Assuming that the current sea level depth is 100 m, first prepare the lower section of the composite material pipe with a length of 100 m through steps 1) to 3). Then, install the mold of the vertical composite material pole tower production equipment in reverse, and prepare the upper section of the composite material pipe with a length of 100 m from bottom to top through the traction equipment at the upper end. After the upper section of the composite material pipe is completed, winding and secondary curing are carried out at the connection of the upper and lower sections of the composite material pipe to fix the composite material pipe into an integral structure with a length of 200 m.
