Description

Technical Field

[0001] The present application belongs to the technical field of conductive material production, and specifically relates to a production device for lightning protection conductive fiber felt. Background Art

[0002] With the continuous increase in the unit capacity of wind turbines, the continuous increase in hub height and impeller diameter, and the development of new types of wind turbines in plateaus, coastal areas, and offshore areas, large wind turbines are increasingly vulnerable to lightning strikes. The blades of wind turbines are always at the highest position of the unit and are the most vulnerable to lightning strikes. They will cause irreversible mechanical damage to the blades of the unit, and their maintenance costs are the highest in the repair costs of lightning damage to the entire unit. Therefore, taking lightning protection measures in the early stage of blade design will greatly reduce the maintenance costs in the later stage.

[0003] At present, there are three main methods for lightning protection of blades: lightning rods and down conductors, segmented guide strips, and lightning protection metal mesh. Lightning rods and down conductors are currently the most widely used lightning protection methods, but as the length of the blade increases, the actual lightning does not always hit the tip of the blade, and sometimes it can cause great damage to the blade body. Segmented guide strips are an emerging method for lightning protection of blades. The use of segmented guide strips and lightning rods and down conductor systems can expand the lightning area of ​​the lightning rods and provide good protection for the blades. The lightning protection metal mesh is a lightning protection method that can act as a lightning rod to receive lightning, and can also act as a down conductor to conduct lightning very well.

[0004] The problems currently faced by the industry using the above solutions are mainly:

[0005] 1. Fatigue and fracture of metal wires or braids. For components with lower vibration frequencies, copper wires or even aluminum wires or their braids can meet the use requirements. However, for components with higher vibration frequencies, the installed metal wires or braids will experience fatigue and fracture during use, and when struck by lightning, charge accumulation will occur, causing abnormal discharge channels and explosion damage to the blades.

[0006] 2. The problem of metal wire or its braided fabric forming process. The current solution is to lay metal wire or braided fabric on the outer layer (the braided fabric is woven in a plain weave) during blade manufacturing, and then lay the last layer of surface. The main problem with this method is that although the lightning protection effect is good, the bonding strength between the top layer and the substrate is weakened, which will cause the surface layer to crack when the lightning receptor discharges and releases heat.

[0007] 3. The most important thing is that metal has its own specific mechanical properties. In the actual production process, it is impossible for it to fit the mold surface very well, and it cannot deform along with the product shape as required by the design, resulting in poor processability.

[0008] Therefore, if alloy fiber felt is used instead of braid and metal wire, the mechanical properties and conductive properties can be well solved. However, there is currently no equipment for making conductive fiber felt. Summary of the invention

[0009] The purpose of this application is mainly to address the shortcomings of the prior art. By setting at least two fiber production and injectors inclined upward in a mixing box, all the fibers ejected from the fiber production and injectors are mixed and then combined with a sintering box, a lightning protection conductive fiber felt production equipment is designed.

DETAILED DESCRIPTION

[0031] like Figure 1-6 As shown, a production equipment for lightning protection conductive fiber felt includes a yarn belt conveyor, a fiber production and injector, a mixing box, a sintering box 3, a negative pressure device 1, and a conveying chain plate 2. At least two fiber production and injectors for upward spraying are obliquely arranged in the mixing box, and the extension lines of the spraying directions of all the fiber production and injectors intersect at a virtual point. The spraying end of the fiber production and injector is located in the mixing box, and the input end of the fiber production and injector is connected to the output end of the yarn belt conveyor outside the mixing box. The conveying chain plate 2 is arranged in the mixing box just below the virtual point, and an opening is provided on the side wall of the mixing box. The conveying starting end of the conveying chain plate is in the mixing box, and the conveying terminal end of the conveying chain plate passes through the opening and extends out of the mixing box. The negative pressure device 1 is arranged in the mixing box just below the conveying chain plate 2, and the part of the conveying chain plate 2 between the conveying terminal and the mixing box is in the sintering box 3.

[0032] In this embodiment, when in use, the metal yarn is wound and hung outside the mixing box, and then one end of the metal yarn 23 is extended into the yarn belt conveyor, and the yarn belt conveyor conveys the end of the metal yarn 23 to the fiber making and injector, so that the metal yarn 23 is made into fiber and sprayed upward. Since at least two fiber making and injectors are provided, each fiber making and injector can make a metal, so that more than two metal fibers can be mixed to form alloy fibers. Since the extension lines of the injection directions of all the fiber making and injectors intersect at a virtual point, all the fibers sprayed by the fiber making and injectors are gathered together (mixed) at the virtual point in the mixing box. After that, the mixed fibers fall downward under the action of their own gravity and the action of the negative pressure device 1, and fall on the conveying chain plate 2 to form an alloy fiber felt. The conveying chain plate 2 conveys the mixed alloy fiber felt to the outside of the mixing box. In the process of the conveying chain plate 2 conveying the mixed alloy fiber felt to the outside of the mixing box, it passes through the sintering box 3, and the sintering box 3 sinters the fibers together, thereby improving the conductive performance of the alloy fiber felt. This solves the problem that there is no equipment for manufacturing conductive alloy fiber felt at present. The conductive alloy fiber felt is coated on the blade. When there is a lightning strike, the lightning will pass through the alloy fiber felt to guide the current to the lightning protection wire, thereby playing a role in lightning protection for the blade and the wind turbine. The conveyor chain motor 22 for driving the conveyor chain plate 2 is arranged in the mixing box.

[0033] As a preferred embodiment, the yarn conveyor includes an upper conveying wheel 4, a lower conveying wheel 5, a conveying motor 6, and a conveying shell 7. The conveying shell 7 has openings at two opposite ends. The upper conveying wheel 4 and the lower conveying wheel 5 are arranged in the conveying shell 7. The axle of the upper conveying wheel 4 is parallel to the axle of the lower conveying wheel 5. One end face of the upper conveying wheel 4 is coplanar with one end face of the lower conveying wheel 5. There is a preset gap between the upper conveying wheel 4 and the lower conveying wheel 5. The output shaft of the conveying motor 6 is drivingly connected to the upper conveying wheel. One end of the conveying shell 7 is connected to the input end of the fiber production and injector.

[0034] After such arrangement, when conveying the metal yarn 23, one end of the metal yarn 23 is extended between the circumferential surface of the upper conveying wheel 4 and the circumferential surface of the lower conveying wheel 5, and the conveying motor 6 drives the upper conveying wheel 4 and the lower conveying wheel 5 to rotate, and the rotation speed of the upper conveying wheel 4 and the lower conveying wheel 5 is the same and the direction is opposite (in this way, a gear 25 can be coaxially fixed on the axle of the upper conveying wheel 4, and a gear 25 can be coaxially fixed on the axle of the lower conveying wheel 5, and then the two gears 25 are meshed, and then the upper conveying wheel 4 is driven by a conveying motor 6, so that the lower conveying wheel 5 can be driven to rotate in the opposite direction at the same time, and the rotation speed is equal to the rotation speed of the upper conveying wheel 4, as shown in FIG. Figure 5As shown in the figure, the purpose of conveying the metal yarn 23 to the fiber making and injector is achieved. The arrangement of the conveying upper wheel 4 and the conveying lower wheel 5 enables the conveyed metal yarn 23 to be located in the center of the fiber making and injector.

[0035] As a preferred embodiment, the fiber making and injector includes an air flow injection device and a fiber making device, a plurality of the air flow injection devices are arranged around the output port of the fiber making device, the injection direction of the air flow injection device is the same as the output direction of the fiber making device, an angle A8 between the injection direction of each of the air flow injection devices and the axis of the output port of the fiber making device is an acute angle, and the opening of the angle A8 faces away from the output direction of the fiber making device.

[0036] After such arrangement, since the airflow jet devices surround the output port of the fiber making device and jet airflow in the output direction of the fiber making device, the air pressure between the input port of the fiber making device and the virtual point is gradually reduced, and the fibers at the output port of the fiber making device fly to the virtual point under the action of air pressure, and are mixed at the virtual point. The angle A8 between the jet direction of the airflow jet device and the axis of the output port of the fiber making device is an acute angle, and the opening of the angle A8 faces away from the output direction of the fiber making device. The purpose of such arrangement is to ensure that the air pressure between the output port of the fiber making device and the virtual point is gradually reduced.

[0037] As a preferred embodiment, the fiber production device includes a production shell 9, an auxiliary roller 10, a cutting roller 11, a first motor 12, and a second motor 13. The production shell 9 is a trumpet-shaped with openings at both ends. The small end of the production shell 9 is connected to the output end of the yarn conveyor, and a plurality of the air flow injection devices are arranged on the edge of the large end of the production shell 9. The auxiliary roller 10 and the cutting roller 11 are both arranged in the production shell 9. A plurality of cutters 14 are arranged on the circumferential surface of the cutting roller 11. The cutters 14 are parallel to the axis of the cutting roller 11, and the blades of the cutters 14 are in contact with the circumferential surface of the auxiliary roller 10. The first motor 12 and the second motor 13 are both fixedly arranged on the production shell 9. The output shaft of the first motor 12 is connected to the cutting roller 11, and the output shaft of the second motor 13 is connected to the auxiliary roller 10.

[0038] After such arrangement, the metal yarn 23 outputted from the output port of the conveying shell 7 moves to the auxiliary roller 10, and the second motor 13 drives the auxiliary roller 10 to rotate. During use, the auxiliary roller 10 rotates in the same direction as the lower conveying wheel 5. After that, the first motor 12 drives the cutter roller 11 to rotate, and the direction of driving the cutter roller 11 to rotate is opposite to the direction of driving the auxiliary roller 10, so that the cutter 14 can cut the metal yarn 23 on the auxiliary roller 10 into fibers. This method cooperates with the arrangement of the upper conveying wheel 4 and the lower conveying wheel 5, so that the conveyed metal yarn 23 can be conveyed to the gap between the cutter roller 11 and the auxiliary roller 10, so that the cutter 14 can cut the metal yarn 23 into fibers.

[0039] As a preferred embodiment, the air flow injection device includes an air pump 15 and a hard ventilation pipe 16. A plurality of the hard ventilation pipes 16 are arranged around the output port of the fiber making device and around the axis of the output port of the fiber making device. The air pump 15 is arranged on the fiber making device, and the input end of the hard ventilation pipe 16 is connected to the output end of the air pump 15. The output end of the hard ventilation pipe 16 faces the output direction of the fiber making device, and an extended line of the output end of the hard ventilation pipe 16 forms an angle A8 with the axis of the output port of the fiber making device.

[0040] After such setting, the air pump 15 blows the air flow through the hard ventilation pipe 16 to the virtual point, thereby bringing the fibers produced in the production shell 9 to the virtual point for mixing. The input end of the air pump 15 is outside the mixing box, and the mixed fibers fall onto the conveying chain plate 2 under the action of their own gravity to form the predecessor of the conductive fiber felt - alloy fiber felt.

[0041] As a preferred embodiment, the system further includes a leveling device, which includes a leveling chain plate 17, a leveling motor 18, and a support frame 19. The leveling chain plate 17 is set on the support frame 19 through a transmission roller. The output shaft of the leveling motor 18 is connected to the transmission roller. The leveling chain plate 17 is located directly above the conveying chain plate 2. The leveling chain plate 17 is parallel to the conveying chain plate 2, and a preset gap is set between the leveling chain plate 17 and the conveying chain plate 2.

[0042] There are many small holes on the conveying chain plate 2, so the negative pressure generated by the negative pressure device 1 can make the fibers fall on the conveying chain plate 2, and the conveying direction of the lower surface of the flattening chain plate 17 is opposite to the conveying direction of the upper surface of the conveying chain plate 2. When in use, the conveying direction of the lower surface of the flattening chain plate 17 is toward the inside of the mixing box, while the conveying direction of the upper surface of the conveying chain plate 2 is toward the outside of the mixing box, so that the flattening chain plate 17 can control the thickness of the alloy fiber felt (conductive fiber felt) on the conveying chain plate 2. The gap set between the flattening chain plate 17 and the conveying chain plate 2 is used to transport the alloy fiber felt to the outside of the mixing box. The air inlet 24 of the negative pressure device 1 is located on the outer wall of the mixing box.

[0043] As a preferred embodiment, the conveying start end of the upper surface of the flattening chain plate 17 is inside the mixing box, and the portion of the flattening chain plate 17 between the outside of the mixing box and the conveying end end of the upper surface of the flattening chain plate is located inside the sintering box 3.

[0044] As a preferred embodiment, the width of the flattening chain plate 17 is equal to the width of the conveying chain plate 2, and the two ends of the flattening chain plate 17 are between the two ends of the conveying chain plate 2. This arrangement can completely flatten the alloy fiber felt on the conveying chain plate 2, and will not cause part of the alloy fiber felt on the conveying chain plate 2 to be not flattened.

[0045] Several installation rollers are rotated in the mixing box, and the installation rollers are parallel to the transmission rollers. The conveying chain plate 2 is sleeved on the whole composed of all the installation rollers, and the conveying chain motor 22 is connected to the installation rollers. When working, the conveying chain motor 22 drives the installation rollers to rotate, thereby driving the conveying chain plate 2 to move. The conveying chain plate 2 is equivalent to the transmission function of the conveyor belt during the conveying process. It is used to transmit alloy fiber felt (conductive fiber felt before sintering).

[0046] As a preferred mode, the mixing box includes a shell 20 and a cover 21. The cover 21 is arranged on one side wall of the shell 20, and an opening for the conveying chain plate to pass through is arranged on a side wall of the shell 20 adjacent to the side wall where the cover 21 is arranged. After such arrangement, the parts in the shell 20 can be installed and repaired by opening the cover 21.
