Technical Field

[0001] The invention relates to the technical field of electric pole processing, and in particular to a production process and system for a composite material electric pole. Background Art

[0002] Traditional electric poles are generally bulky, easy to rot, rust or crack, and have a short lifespan. They are difficult to construct, transport, operate and maintain, and are prone to various safety hazards. With the development of new material technology and its preparation process, composite materials have developed rapidly. Composite poles have the advantages of light weight, corrosion resistance, high strength, and longer life. They have low maintenance costs and can withstand extreme climatic conditions. They can well replace traditional wooden poles, reinforced concrete poles and iron towers in power transmission and distribution lines, communication lines, communication towers and other projects.

[0003] At present, composite poles have been used in transmission towers. However, there are still many key problems in the processing technology of composite tapered poles that have not been solved, which may result in high production costs or insufficient strength and stiffness of the produced tapered poles. Summary of the invention

[0004] The object of the present invention is to provide a production process and system for composite material electric poles, and the composite material electric poles manufactured by the process have high strength and long service life.

[0005] In order to solve the above technical problems, the present invention adopts the following solutions: A production process for composite material electric poles. A: The inner layer component is positioned on the output shaft of the first mobile transmission box, and the first mobile transmission box moves along the axial direction of the inner layer component, while driving the inner layer component to rotate; B: Axial wiring, the wiring ring first lays the base layer on the surface of the inner layer along the axial direction of the inner layer until the base layer is laid to the set thickness; C: Circumferential wiring, and then the same wiring ring is used to lay the center line layer in the circumferential direction of the inner layer, and the center line layer is pressed on the base line layer until the center line layer is laid to the set thickness; D: Wrap the outer layer on the outside of the center line layer, and wrap the outer layer in a spiral trajectory until the outer layer is wound to the set thickness to form the required pole.

[0006] In this scheme, a multi-layer structure is arranged on the surface of the inner layer according to the process sequence. First, a base line layer is arranged on the surface of the inner layer along its axial direction through a wiring ring. The base line layer is distributed along the axial direction of the inner layer to form a rib effect, thereby improving the strength and stiffness of the inner layer. After the base line layer is arranged, a center line layer is arranged on the surface of the inner layer along its circumference through the same wiring ring. The center line layer tightly wraps the base line layer, and the center line layer further improves the stiffness of the pole. After the center line layer is arranged, an outer layer is wound around the outside of the center line layer. The outer layer is wound in a spiral track overlap winding manner, and the winding thickness reaches the required pole requirement. In this way, the outer layer firmly wraps the center line layer and the base line layer on the surface of the inner layer. The center line layer and the base line layer increase the strength and stiffness of the pole. The outer layer can protect the base line layer and the center line layer to avoid accidental damage and extend the service life of the pole.

[0011] Optionally, before laying the baseline layer, the inner layer component is first positioned on the output shaft of the second mobile transmission box, and then a first groove for laying the baseline layer is opened on the surface of the inner layer component. The first groove is distributed axially along the inner layer component, and the number of first glass fiber lines arranged in the first groove depends on the thickness of the baseline layer.

[0012] Optionally, after the first groove is opened, two second grooves are opened on the surface of the inner layer component. The two second grooves are distributed in a spiral shape, and the spiral directions of the two second grooves are opposite. The two spiral second grooves are in a grid shape on the surface of the inner layer component. The depth of the second groove is less than the depth of the first groove. Reinforcing ribs are arranged in the second grooves, and the reinforcing ribs are glass fiber lines.

[0013] Optionally, after the second groove is opened, an annular third groove is opened at both ends of the inner layer member, the third groove is connected to the second groove, and the third groove serves as a transition zone when the reinforcing rib line is laid out.

[0016] The present invention has the beneficial effects: 1. In the present invention, firstly, a base line layer is arranged on the surface of the inner layer member along its axial direction through a wiring ring. The base line layer is distributed along the axial direction of the inner layer member to form a rib effect, thereby improving the strength and stiffness performance of the inner layer member. After the base line layer is arranged, a center line layer is arranged on the surface of the inner layer member along its circumference through the same wiring ring. The center line layer tightly wraps the base line layer, and the center line layer further improves the stiffness performance of the pole. After the center line layer is arranged, an outer layer is wound around the outer side of the center line layer. The outer layer adopts a spiral track overlap winding method, and the winding thickness reaches the required pole requirement. In this way, the outer layer firmly wraps the center line layer and the base line layer on the surface of the inner layer member. The center line layer and the base line layer increase the strength and stiffness performance of the pole. The outer layer can protect the base line layer and the center line layer to avoid accidental damage and extend the service life of the pole. The outer layer further improves the strength and stiffness performance of the pole. The whole process is simple and reliable. The pole produced by this process has high strength and stiffness performance and longer service life.

[0017] 2. Opening the first axial groove on the surface of the inner layer can produce a certain pressure effect around the first groove. This pressure effect helps to increase the strength and hardness of the later pole, so that the stress distribution of the pole is more uniform when the pole is subjected to external force, thereby improving the overall strength of the pole and improving the surface morphology and structure. Grooving can also improve the morphology and structure of the surface of the inner layer, reduce stress concentration points, and make the later pole less likely to break when subjected to external force.

[0018] 3. The two second grooves are spirally cross-distributed to form a grid groove. The design of the grid groove can effectively disperse the stress generated by the inner layer when it is subjected to force, avoiding cracking or deformation caused by stress concentration. By dispersing the stress to the entire surface of the inner layer, the grid groove can significantly improve the tensile strength and bending strength of the later pole.

[0019] 4. A first glass fiber wire is arranged in the first groove, and the first groove is also distributed in a ring shape in the circumference of the inner layer component. In this way, after the first glass fiber wire is arranged to a certain thickness, the first glass fiber wire in each first groove will form a reinforcing rib on the surface of the inner layer component, thereby enhancing the bending strength of the inner layer component and the strength and stiffness of the pole after later molding. At the same time, the first groove can also prevent the first glass fiber wire from slipping out.

[0020] 5. The second groove is provided with glass fiber reinforcement lines, which are distributed in a grid pattern, further improving the strength performance of the inner layer, thereby improving the strength and stiffness performance of the later formed pole. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention will be further described in detail below in conjunction with embodiments and drawings, but the embodiments of the present invention are not limited thereto.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] A production process for composite material electric poles. A: The inner layer component 2 is positioned on the output shaft of the first mobile transmission box 1, and the first mobile transmission box 1 moves along the axial direction of the inner layer component 2, while driving the inner layer component 2 to rotate; B: Axial wiring, the wiring ring first lays the base layer 4 on the surface of the inner layer 2 along the axial direction of the inner layer 2 until the base layer 4 is laid to a set thickness; C: Circumferential wiring, and then the same wiring ring is used to lay the center line layer 5 in the circumferential direction of the inner layer 2, and the center line layer 5 is pressed on the base line layer 4 until the center line layer 5 is laid to a set thickness; D: Wind the outer layer 10 outside the center line layer 5, and the outer layer 10 is wound in a spiral track and overlapped until the outer layer 10 is wound to a set thickness to form the required pole.

[0026] In this embodiment, Figure 1As shown, the inner layer component 2 is positioned on the output shaft of the first mobile transmission box 1. The inner layer component 2 can be a mold or an inner lining of a later formed pole. If the inner layer component 2 is an inner lining, the inner lining is generally a hollow rod. If the inner layer component is a mold, it needs to be removed after the pole is formed. The inner layer component 2 in this scheme is a hollow rod, which is a part of the pole later. Two first mobile transmission boxes 1 can be set. The inner layer component 2 is located between the two first mobile transmission boxes 1. The first mobile transmission box 1 can move along the axial direction of the inner layer component 2 and can also drive the inner layer component 2 to rotate clockwise or counterclockwise. This step provides a basis for the subsequent wiring process and ensures that the inner layer component 2 can rotate and move stably during the wiring process. The inner layer component 2 itself is also made of composite materials. The hollow interior can reduce the weight of the later formed pole. The inner layer component 2 can be straight or conical. A multilayer structure is arranged on the surface of the inner layer 2 according to the process sequence. First, a base line layer 4 is arranged on the surface of the inner layer 2 along its axial direction through a wiring ring. The base line layer 4 is distributed along the axial direction of the inner layer 2 to form a rib effect, thereby improving the strength and stiffness of the inner layer 2. After the base line layer 4 is arranged, a center line layer 5 is arranged on the surface of the inner layer 2 along its circumference through the same wiring ring. The center line layer 5 tightly wraps the base line layer 4. The center line layer 5 further improves the stiffness of the pole. After the center line layer 5 is arranged, an outer layer 10 is wound around the outer side of the center line layer 5. The outer layer 10 adopts The spiral track overlap winding method is used, and the winding thickness reaches the required pole requirement, so that the outer layer 10 wraps the center line layer 5 and the base line layer 4 firmly on the surface of the inner layer 2, and the center line layer 5 and the base line layer 4 increase the strength and stiffness of the pole. The outer layer 10 can protect the base line layer 4 and the center line layer 5 to avoid accidental damage and extend the service life of the pole. The outer layer 10 further improves the strength and stiffness of the pole. The whole process is simple and reliable. The pole produced by this process has high strength and stiffness and a longer service life.

[0027] Furthermore, the base layer 4 includes a plurality of first glass fiber lines 401 impregnated with resin, and the plurality of first glass fiber lines 401 are distributed in a ring shape in the circumferential direction of the inner layer component 2 , and the plurality of first glass fiber lines 401 are distributed axially along the inner layer component 2 .

[0028] Specifically, Figure 7 As shown, the base layer 4 is composed of a plurality of first glass fiber lines 401 , which are distributed in a ring shape around the inner layer 2 , and the first glass fiber lines 401 are parallel to the axis of the inner layer 2 .

[0029] Enhanced structural strength: The glass fiber wire itself has high strength and rigidity, and its structural performance and corrosion resistance can be further improved by dipping. Forming the base layer 4 on the inner layer 2 can effectively enhance the overall structural strength of the pole, enabling it to withstand greater external pressure and load.

[0030] Improve insulation performance: Glass fiber wire is a good insulating material, especially after being impregnated, its insulation performance is further improved. Therefore, the base layer 4 can not only provide structural support, but also serve as an insulating layer of the pole to prevent current leakage through the surface of the pole.

[0031] Axial distribution and circumferential annular design: This design ensures the uniform distribution of the base layer 4 on the inner layer 2. Each glass fiber line is distributed along the axial direction and can provide continuous axial support. The circumferential annular distribution ensures the integrity of the base layer 4 around the pole, enabling it to effectively resist external pressure from all directions.

[0032] Furthermore, the center line layer 5 includes a plurality of second glass fiber lines 501 impregnated with resin, and the plurality of second glass fiber lines 501 are tightly wound around the outside of the first glass fiber line 401 , and two adjacent second glass fiber lines 501 are tightly fitted.

[0033] Specifically, Figure 3 As shown, the center line layer 5 is composed of a plurality of second glass fiber lines 501 dipped in glue, and the second glass fiber lines 501 are tightly wound around the outside of the base line layer 4. In addition, two adjacent second glass fiber lines 501 are tightly fitted to form a continuous and dense covering layer. This design has several key features and functions: Enhanced structural density and strength: Through close winding and fitting, the second glass fiber line 501 forms a continuous and dense fiber network in the center line layer 5. This structure not only enhances the overall density of the center line layer 5, but also improves its structural strength, enabling it to better withstand external pressure and load.

[0034] Improved durability and corrosion resistance: The resin dipping treatment not only enhances the structural performance of the glass fiber wire, but also improves its durability and corrosion resistance. In the center line layer 5, the tightly fitted glass fiber wire forms a cylindrical protective layer 11, which can resist erosion by moisture, chemicals, etc. in the external environment, thereby extending the service life of the pole.

[0035] Optimizing the conductive or insulating properties: Although the glass fiber wire itself has insulating properties, the compact structure and the resin dipping treatment of the center layer 5 may further optimize its conductive or insulating properties. In situations where insulation protection is required, it can ensure that the current will not leak through the center layer 5; and in situations where conductive properties are required, this can be achieved by adding conductive materials or processing techniques.

[0036] Improved appearance and workmanship: The tightly fitting glass fiber wire not only gives the center line layer 5 a smooth appearance, but also helps to improve the workmanship and aesthetics of the entire pole. During the manufacturing process, this design can simplify the construction steps and improve production efficiency.

[0037] Furthermore, the outer layer 10 is composed of a unidirectional cloth 1001, which is spirally wound from one end of the inner layer 2 to the other end. The unidirectional cloth 1001 is wound in an overlapping manner. The outer layer 10 has multiple layers, and the spiral directions of adjacent layers are opposite. During the winding process of the unidirectional cloth 1001, resin is continuously applied to the unidirectional cloth 1001.

[0038] Specifically, Figure 6 As shown, the outer layer 10 uses a high-strength unidirectional cloth 1001, and the unidirectional cloth 1001 is spirally wound from one end of the inner layer 2 to the other end. The unidirectional cloth 1001 is wound in an overlapping manner, and the outer layer 10 forms a multi-layer structure, and the spiral directions between the upper and lower adjacent layers are opposite. In the process of winding the unidirectional cloth 1001, resin is continuously applied to the unidirectional cloth 1001.

[0039] It has the following advantages: Enhanced structural strength: Due to the consistent arrangement direction of its fibers, unidirectional fabric 1001 has excellent tensile strength and shear strength. When multiple layers of unidirectional fabric 1001 are wound on the pole in opposite spiral directions, they can support each other to form a continuous and stable fiber network, thereby greatly enhancing the structural strength of the pole.

[0040] Improve durability: Resin coating can not only enhance the bonding force between the one-way fabrics 1001, but also form a protective film to prevent moisture, chemicals, etc. in the external environment from corroding the poles, making the poles more durable and corrosion-resistant, and extending their service life.

[0041] Optimize crack resistance: Since the unidirectional fabrics 1001 are wound in a spiral shape, they can disperse external pressure and reduce cracks caused by concentrated stress. At the same time, the spiral directions between two adjacent layers are opposite. This design can further offset internal stress and improve the crack resistance of the pole.

[0042] Improved workmanship and aesthetics: The spiral winding and overlapping method makes the construction easier and improves the production efficiency. At the same time, this design can also make the pole have a smooth appearance and improve the aesthetics.

[0043] Adapt to different environments: The outer layer 10 of the resin-coated unidirectional fabric 1001 can be customized as needed to adapt to different environmental conditions. For example, in a humid or corrosive environment, a resin and unidirectional fabric 1001 material with higher corrosion resistance can be selected. In summary, the design of the outer layer 10 not only enhances the structural strength and durability of the pole, but also optimizes its crack resistance and processability by adopting processes such as spiral winding, overlapping, and resin coating of the unidirectional fabric 1001. It has broad application prospects in the production of poles in the fields of electricity, communications, etc., and can meet the use requirements under different environmental conditions.

[0044] Furthermore, after the outer layer 10 is wound, an adhesive is applied to the surface of the outer layer 10, and finally a protective layer 11 is wrapped around the outer layer 10. The protective layer 11 is coated with resin, and particles are added to the resin. The protective layer 11 is made of wear-resistant material, and the protective layer 11 is dried after being laid.

[0045] Specifically, after the outer layer 10 is wound, a series of subsequent treatments are performed, including applying adhesive, wrapping the protective layer 11, applying resin containing particles on the protective layer 11, and drying. This design has several key features and functions: Enhanced bonding strength: The main purpose of applying adhesive on the surface of the outer layer 10 is to enhance the bonding strength between the protective layer 11 and the outer layer 10, which can ensure that the protective layer 11 can be firmly attached to the outer layer 10 and is not easy to fall off or loosen, thereby improving the structural integrity and durability of the entire pole.

[0046] Improve wear resistance and corrosion resistance: The protective layer 11 is made of wear-resistant material, which can significantly improve the wear resistance of the pole, enabling it to resist friction and wear in the external environment. At the same time, brushing a resin containing particulate matter on the protective layer 11 can further enhance its corrosion resistance, because the particulate matter can increase the roughness of the resin surface and improve its isolation effect from the external environment.

[0047] Increased anti-slip performance: The particles added to the resin can not only improve the corrosion resistance, but also increase the anti-slip performance of the protective layer 11, which helps prevent the pole from sliding or tipping over when used on wet or slippery ground, thereby improving safety in use.

[0048] Drying treatment: Drying is an important step to ensure that the protective layer 11 and the resin layer can be firmly cured and exert their performance. Through the drying treatment, the moisture and volatile substances in the protective layer 11 and the resin layer can be removed, making them stronger and more durable. This series of subsequent treatments not only enhances the structural strength and durability of the pole, but also improves its wear resistance, corrosion resistance, anti-slip performance and processability, which enables the pole to maintain stable performance under various harsh environmental conditions and extend its service life. In summary, the subsequent processing process after the outer layer 10 is wound is to significantly improve the comprehensive performance of the pole by applying adhesive, wrapping the protective layer 11 of wear-resistant material, applying resin containing particulate matter and drying. This design method has broad application prospects in the production of poles in the fields of electricity, communications, etc., and can meet the use requirements under different environmental conditions.

[0049] Furthermore, before laying out the baseline layer 4, the inner layer component 2 is first positioned on the output shaft of the second mobile transmission box 13, and then a first groove 6 for laying out the baseline layer 4 is opened on the surface of the inner layer component 2. The first groove 6 is distributed axially along the inner layer component 2, and the number of first glass fiber lines 401 arranged in the first groove 6 is determined according to the thickness of the baseline layer 4.

[0050] Specifically, before laying the base layer 4, the positioning and pretreatment process of the inner layer 2 includes the following key steps: Positioning of the inner layer component 2: First, the inner layer component 2 is positioned on the output shaft of the second mobile transmission box 13. This step ensures that the pole can be moved stably and accurately during subsequent processing, and provides necessary positioning support for laying the baseline layer 4. The second mobile transmission box 13 and the first mobile transmission box 1 have the same structure and function, and both are commonly used driving components in the process of making poles.

[0051] like Figure 4 As shown, a first groove 6 is opened: then, a first groove 6 for laying out the baseline layer 4 is opened on the surface of the inner layer 2. This groove is distributed along the axial direction of the inner layer 2, providing a specific space for laying out the baseline layer 4. The depth and width of the groove can be adjusted according to the expected thickness of the baseline layer 4 and the diameter of the glass fiber line to ensure that the baseline layer 4 can be firmly embedded therein.

[0052] Determine the number of glass fiber lines: The number of first glass fiber lines 401 set in the first groove 6 is determined according to the thickness of the baseline layer 4. By adjusting the number of glass fiber lines, the thickness and density of the baseline layer 4 can be controlled to meet different structural strength requirements. This step requires precise calculation to ensure that the baseline layer 4 can provide sufficient support and stability.

[0053] Laying out the baseline layer 4: After the positioning of the inner layer 2 and the opening of the first groove 6 are completed, the baseline layer 4 can be laid out. The baseline layer 4 is composed of a plurality of first glass fiber lines 401 impregnated with glue. The first glass fiber lines 401 are tightly embedded in the first groove 6 to form a continuous and dense fiber network. By adjusting the number and arrangement of the first glass fiber lines 401, the structural performance of the baseline layer 4 can be further optimized. The first glass fiber lines 401 are laid out in the first groove 6, and the first grooves 6 are also distributed in the circumference of the inner layer 2 in a ring shape. In this way, after the first glass fiber lines 401 are laid out to a certain thickness, the first glass fiber lines 401 in each first groove 6 will form a reinforcing rib on the surface of the inner layer 2, thereby enhancing the bending strength of the inner layer 2 and the strength and stiffness of the pole after later molding. At the same time, the first groove 6 can also prevent the first glass fiber lines 401 from slipping out.

[0054] Further, such as Figure 5 As shown, after the first groove 6 is opened, two second grooves 7 are opened on the surface of the inner layer 2. The two second grooves 7 are distributed in a spiral shape, and the spiral directions of the two second grooves 7 are opposite. The two spiral second grooves 7 are in a grid shape on the surface of the inner layer 2. The depth of the second groove 7 is less than the depth of the first groove 6. A reinforcing rib line 9 is arranged in the second groove 7, and the reinforcing rib line 9 is a glass fiber line.

[0055] Specifically, the two second grooves 7 are distributed in a spiral shape, and their spiral directions are opposite, so that the two second grooves 7 form a grid-like structure on the surface of the inner layer 2. This grid-like structure not only increases the complexity of the pole surface, but also improves its structural strength and stability. The depth of the second groove 7 is less than the depth of the first groove 6. The design of this depth difference may be to ensure the structural strength while avoiding excessive impact on the overall structure of the pole. By adjusting the depth of the groove, the embedding degree of the reinforcing rib wire 9 and the flatness of the pole surface can be accurately controlled. The reinforcing rib wire 9 is arranged in the second groove 7. The reinforcing rib wire 9 is a glass fiber wire. The glass fiber wire has high strength and corrosion resistance. By embedding the reinforcing rib wire 9 in the second groove 7, the bending strength and shear strength of the pole can be further improved. By opening the second groove 7 and arranging the reinforcing rib wire 9, the structural performance of the pole is significantly improved. This design not only enhances the strength and stability of the pole, but also improves its durability and corrosion resistance, which enables the pole to better adapt to the use requirements under various harsh environmental conditions.

[0056] Furthermore, after the second groove 7 is formed, an annular third groove 8 is formed at both ends of the inner layer 2 . The third groove 8 is connected to the second groove 7 , and the third groove 8 serves as a transition zone when the reinforcing rib line 9 is laid out.

[0057] Specifically, since the inner layer component 2 is in a rotating state when the reinforcing rib wire 9 is spirally wound, the reinforcing rib wire 9 needs to be wound from one end of the inner layer component 2 to the other end, and wound back and forth until it reaches an appropriate thickness. In order to ensure the continuity of the reinforcing rib wire 9, when the reinforcing rib wire 9 is wound from the left end to the right end, the lateral movement of the second mobile transmission box 13 can be stopped, but the inner layer component 2 needs to continue to rotate. At this time, after the reinforcing rib wire 9 is wound around the third groove 8 for one circle, the second mobile transmission box 13 drives the inner layer component 2 to rotate in the opposite direction, and the reinforcing rib wire 9 can be embedded in another spiral second groove 7, and so on and so forth until the reinforcing rib wire 9 reaches the set thickness. In this way, it can be ensured that the reinforcing rib wire 9 will not be cut off midway, thereby ensuring the continuity of the reinforcing rib wire 9 and improving the stiffness and strength performance of the pole.
