DETAILED DESCRIPTION

[0046] The exemplary embodiments will be described in detail herein with reference to the attached drawings. The same reference numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments are not meant to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the present application as detailed in the appended claims.

[0047] In the related art, a submarine cable includes a core layer and an armor layer wrapped outside the core layer, wherein the armor layer is made by twisting and coating a plurality of steel wires on the core layer. In order to ensure the corrosion resistance of the steel wires during use, bitumen is coated on the steel wires.

[0048] The way of coating bitumen on the steel wires is that the steel wires are twisted and coated on the core layer by using a twisting device, and then bitumen paste is poured on the whole formed by the steel wires and the core layer, so that the bitumen paste is coated on the surface of the steel wires.

[0049] However, when the steel wires are coated with bitumen in the above-mentioned way, the contact surface of each steel wire with the steel wire, or the side of the steel wire facing the core layer, is easy to be not coated with bitumen, which leads to uneven coating of the bitumen paste on the steel wires and poor corrosion resistance of the steel wires.

[0050] Thus, the wire coating device provided by the embodiment of the present application comprises a rack, a rotating assembly, a coating assembly, and the rotating assembly is rotatably arranged on the rack and used for being connected with a stranding device of a wire, a plurality of accommodating channels are arranged on the rotating assembly and penetrate through the rotating assembly along an axial direction of the rotating assembly, the accommodating channels are used for corresponding wire penetration on the rotating assembly, and the coating assembly is used for spraying slurry into the accommodating channels so that the slurry is coated on the wire from the accommodating channels. Thus, before the steel wires are stranded and coated on the core layer, the steel wires can be correspondingly penetrated in the accommodating channels, the rotating assembly supports the rotation of the steel wires, the steel wires can move relative to the accommodating channels under the support of the rotating assembly, and then the steel wires are stranded and coated on the core layer. During this period, the coating assembly sprays asphalt into the accommodating channels, and with the rotation of the rotating assembly, the asphalt in the accommodating channels can be coated on the steel wires from multiple angles, the asphalt coating on the steel wires is more comprehensive, the asphalt coating effect on the steel wires is improved, the problem of uneven asphalt slurry coating on the steel wires in the related art is solved, and the corrosion resistance of the steel wires is poor. Meanwhile, the rotating assembly also has a better wire separating function on the plurality of steel wires, reduces the use of a wire separator when the steel wires are stranded and coated on the core layer, and simplifies the installation steps of the wire separator.

[0052] As shown in Figure 1 , the wire coating device provided by the embodiment of the present application comprises:

[0053] a rack 100;

[0054] a rotating assembly 200, the rotating assembly 200 is rotatably arranged on the rack 100 and used for being connected with a stranding device of a wire, a plurality of accommodating channels 300 are arranged on the rotating assembly 200 and penetrate through the rotating assembly 200 along an axial direction of the rotating assembly 200, and the accommodating channels 300 are used for corresponding wire penetration on the rotating assembly 200;

[0055] a coating assembly 400, the coating assembly 400 is used for spraying slurry into the accommodating channels 300 so that the slurry is coated on the wire from the accommodating channels 300.

[0056] It should be noted that the accommodation channel 300 is used to correspondingly pass the wire, wherein the wire can be determined according to actual needs, for example, can be a steel wire, a cable or other wires. The coating assembly 400 is used to spray the slurry to be coated into the accommodation channel 300, wherein the slurry to be coated can be determined according to actual needs, for example, can be asphalt, waterproof paint or other paint. In this embodiment, the wire is taken as an example of a steel wire, and the slurry to be coated is taken as an example of asphalt.

[0057] In implementation, the steel wire usually passes through the wire distributor and is then drawn and twisted by the twisting device to be wrapped on the core layer, wherein the wire distributor and the twisting device can be existing products, which are not limited in this embodiment. Secondly, the wire coating device is installed between the wire distributor and the twisting device, so that the steel wire is correspondingly passed into each accommodation channel 300 before being twisted and wrapped on the core layer, so that the rotating assembly 200 supports the rotation of each steel wire, and the steel wire can move relative to the accommodation channel 300 under the support of the rotating assembly 200. That is, each steel wire will pass through the accommodation channel 300 and then be twisted and wrapped on the core layer.

[0058] During the process, the asphalt is sprayed into each accommodation channel 300 by the coating assembly 400, so that the asphalt is more comprehensively coated on the steel wire from the accommodation channel 300, improving the coating effect of the asphalt on the steel wire and solving the problem of uneven coating of the asphalt slurry on the steel wire in the related art, so that the corrosion resistance of the steel wire is poor.

[0059] In some embodiments, the rotating assembly 200 also has a better wire distribution function for multiple steel wires, thereby reducing the use of the wire distributor when the steel wire is twisted and wrapped on the core layer, and simplifying the installation steps of the wire distributor.

[0060] It should be noted that the rotation speed of the rotating assembly 200 matches the twisting speed of the steel wire driven by the twisting device, which can reduce the possibility of mutual interference or winding of each steel wire during the drawing process.

[0061] As shown in Figure 1 In some embodiments, the rotating assembly 200 includes a transmission turntable 210 and a rotating bracket 220, the transmission turntable 210 is rotationally arranged on the rack 100, and the rotating bracket 220 is coaxially connected to the transmission turntable 210, and the accommodation channel 300 is arranged on the rotating bracket 220.

It can be understood that the transmission turntable 210 is driven to rotate by the driving assembly 500, and then the rotating support 220 is driven to rotate by the transmission turntable 210.

[0064] As shown in Figure 1 and Figure 2 In the embodiment, a plurality of containing channels 300 are uniformly distributed on the rotating support 220 around the rotation axis of the rotating assembly 200. The containing channels 300 penetrate the rotating support 220 along the axial direction of the rotating support 220, so that both ends of the containing channels 300 extend to the two opposite sides of the rotating support 220 in the axial direction. A plurality of flow guide holes 310 are formed in the peripheral wall of the rotating support 220 in the rotating assembly 200, and the flow guide holes 310 correspond to the containing channels 300.

[0065] The coating assembly 400 is used for spraying the slurry from the peripheral side of the rotating assembly 200 to the rotating support 220 in the rotating assembly 200.

[0066] In implementation, the steel wires pass through the containing channels 300 on the rotating support 220 and are then twisted and coated on the core layer. During this process, the driving assembly 500 drives the transmission turntable 210 to rotate, so as to drive the rotating support 220 to rotate, thereby driving a plurality of steel wires to rotate around the rotation axis of the rotating support 220. At the same time, the coating assembly 400 sprays the asphalt to the peripheral wall of the rotating support 220, and the asphalt enters the containing channels 300 from the flow guide holes 310 during the rotation of the rotating support 220, and then the asphalt can be coated on the surface of the steel wires in the containing channels 300.

[0067] In implementation, a plurality of support holes 211 distributed around the rotation axis can be formed on the transmission turntable 210, each support hole 211 corresponds to each containing channel 300, so that the steel wires can pass through the containing channels 300 and the support holes 211 at the same time. In this way, each steel wire can be supported by the transmission turntable 210 and the rotating support 220 at the same time, the extension trajectory of the steel wire is stabilized, the stability of the steel wire when passing through the containing channels 300 is improved, and the coating effect of the asphalt on the steel wire is optimized.

[0068] As shown in Figure 1 In some embodiments, the driving assembly 500 includes a driving member and at least one pair of support guide wheels 510, the support guide wheels 510 are rotationally arranged on the rack 100, and the transmission turntable 210 is arranged on each support guide wheel 510 at the same time.

[0069] The driving member is used for driving at least one support guide wheel 510 to rotate, so as to drive the transmission turntable 210 to rotate through the support guide wheel 510.

[0070] In the embodiment, the support guide wheels 510 can be arranged in pairs, each of the support guide wheels 510 is rotationally connected to the frame 100 around a horizontal rotation axis, and the two support guide wheels 510 are spaced apart. The support guide wheels 510 can be rotationally connected to the frame 100 through a rotating shaft. The transmission turntable 210 is arranged on the two support guide wheels 510 at the same time, so that the support guide wheels 510 and the transmission turntable 210 can be driven by each other.

[0071] The driving member can be a motor and the model is not limited. The driving member can be drivingly connected to one of the support guide wheels 510 through gears, chains or other means, so that the driving member can drive one of the support guide wheels 510 to rotate, thereby driving the transmission turntable 210 and the rotating bracket 220 to rotate.

[0072] In other embodiments, the support guide wheels 510 can also be arranged in multiple pairs, and the transmission turntable 210 abuts against multiple support guide wheels 510 at the same time. In addition, the driving member can also be drivingly connected to multiple support guide wheels 510 at the same time to drive multiple support guide wheels 510 to rotate at the same time, thereby driving the transmission turntable 210 to rotate.

[0073] As shown in FIG. 1, Figure 1 In some embodiments, the coating assembly 400 includes:

[0074] A bin body 410, the bin body 410 is arranged on the periphery of the rotating assembly 200, the interior of the bin body 410 has a material cavity 450, the bin body 410 is provided with multiple spray holes 411 facing the rotating assembly 200, the spray holes 411 are communicated with the material cavity 450;

[0077] A first driving pump, the first driving pump is arranged on the feeding pipe 430 and is used for driving the slurry in the slurry container 420 to flow to the material cavity 450.

[0078] In the embodiment, the slurry container 420 can be a box structure or a tank structure, and the specific structure is not limited, as long as it can contain asphalt or other slurry to be coated. The two ends of the feeding pipe 430 are respectively communicated with the interior of the slurry container 420 and the material cavity 450 of the bin body 410. The first driving pump is arranged on the feeding pipe 430 to drive the slurry in the slurry container 420 to flow to the material cavity 450 through the first driving pump.

[0079] The bin body 410 is arranged on the periphery of the rotating bracket 220, and each of the spray holes 411 on the bin body 410 faces the peripheral wall of the rotating bracket 220.

[0080] In practice, the end of the feeding pipe 430 can be connected with the slurry container 420 or the housing 410 by screwing, welding, flange connection or other means. The first driving pump can be a pipeline pump, a centrifugal pump or other types, which are not limited.

[0081] In operation, the asphalt in the slurry container 420 is pumped into the material cavity 450 by the first driving pump, and then the asphalt in the material cavity 450 can be sprayed onto the peripheral wall of the rotating support 220 through the spray hole 411, and then enters the containing channel 300 through the flow guide hole 310, and then is coated on the steel wire.

[0082] As shown in Figure 1 and Figure 3 , further, the housing 410 includes a coating bin 412 and a backflow bin 413;

[0083] The coating bin 412 is located above the rotating assembly 200, and the material cavity 450 and the spray hole 411 are arranged on the coating bin 412;

[0084] The backflow bin 413 is located below the rotating assembly 200, and the backflow bin 413 has a backflow groove with an opening upward, so as to collect the slurry dripping from the rotating assembly 200 through the backflow groove.

[0085] Specifically, the backflow bin 413 is arranged directly below the rotating support 220, and the backflow bin 413 has a backflow groove with an opening upward, and the opening of the backflow groove corresponds to the rotating support 220.

[0086] The coating bin 412 can be fixed on the upper end of the backflow bin 413 by screwing, welding or other means, so that the backflow bin 413 serves as the base of the coating bin 412. Secondly, the coating bin 412 can be an arc structure, so that the extension track of the coating bin 412 is arranged around the rotating support 220, that is, the coating bin 412 extends to the side and above the rotating support 220.

[0087] The material cavity 450 and the spray hole 411 are arranged on the coating bin 412, the spray hole 411 faces the rotating support 220, and a plurality of spray holes 411 are arranged around the rotating support 220. It can be understood that at this time, the two ends of the feeding pipe 430 are respectively communicated with the inside of the slurry container 420 and the material cavity 450 on the coating bin 412.

[0088] In operation, the asphalt entering the material cavity 450 is sprayed onto the peripheral wall of the rotating support 220 through the spray hole 411, and then enters the containing channel 300 through the flow guide hole 310, and then is coated on the steel wire. Secondly, the excess asphalt on the rotating support 220 will drip downward into the backflow groove in the backflow bin 413, so as to collect and reuse the excess asphalt, reducing the waste of asphalt.

[0089] That is, as the rotating support 220 rotates, each asphalt guide hole 310 receives asphalt sprayed from the different orientation spray holes 411 at different positions, ensuring that each steel wire is coated with asphalt 360 degrees without dead angles. When each containing channel 300 rotates to the lowermost position, the excess asphalt under the action of gravity is dripped into the return groove in the return bin 413 through the corresponding guide hole 310.

[0090] As shown in Figure 1 In some embodiments, the coating assembly 400 further comprises a return pipe 440 and a second driving pump;

[0091] The return pipe 440 connects the return groove with the interior of the slurry container 420;

[0092] The second driving pump is arranged on the return pipe 440 and is used to drive the slurry in the return groove to flow to the slurry container 420.

[0093] The end of the return pipe 440 can be connected to the slurry container 420 or the return bin 413 by screwing, welding, flange connection or other means. The second driving pump can be connected to the return pipe 440 by screwing, flange connection, welding or other means. The second driving pump can be a pipeline pump, a centrifugal pump or other types, which are not limited.

[0094] Thus, the excess asphalt on the rotating support 220 can be collected in the return groove in the return bin 413 after falling downward, and the collected asphalt in the return groove can be sent back to the slurry container 420 by the second driving pump, facilitating the recycling of the asphalt.

[0095] As shown in Figure 1 In some embodiments, the wire coating device further comprises a pressurizing device 600, the pressurizing device 600 is connected to the material cavity 450, and the pressurizing device 600 is used to pressurize the material cavity 450.

[0097] During operation, the pressurizing device 600 can input gas or liquid (such as slurry) into the material cavity 450 to increase the pressure in the material cavity 450, so that the asphalt in the material cavity 450 can be more stably sprayed from the spray hole 411, and the spraying effect of the asphalt on the rotating support 220 is optimized. The pressurizing device 600 can be an air compressor, a gas pump or other pressurizing devices, which are not limited.

[0098] As shown in Figure 1As shown, in some embodiments, the wire coating device further comprises at least one heating element 700, at least one of the coating bin 412, the feeding pipe 430, the backflow bin 413 and the backflow pipe 440 is provided with the at least one heating element 700, and the heating element 700 is used for heating the slurry.

[0099] The heating element 700 can be an electric heating rod, an electric heating plate, an electric heating belt or other forms, which are not limited.

[0100] For example, in the embodiment, the coating bin 412 is provided with the heating element 700, which is selected as an electric heating rod. Specifically, two electric heating rods are arranged at the opposite ends of the material cavity 450 in the extension direction. In order to heat the asphalt in the material cavity 450 by the electric heating rod, the possibility of solidification of the asphalt in the material cavity 450 is reduced.

[0101] The heating element 700 can be an electric heating rod, an electric heating plate, an electric heating belt or other forms, which are not limited.

[0102] The heating element 700 can be an electric heating rod, an electric heating plate, an electric heating belt or other forms, which are not limited.

[0103] In other embodiments, the installation position of the heating element 700 can be reasonably set according to actual needs, so as to ensure that the asphalt is not easy to solidify in the whole coating process.

[0104] In some embodiments, the wire coating device can further comprise a controller and a temperature detection element, the temperature detection element is electrically connected to the controller, and the temperature detection element is used for detecting the temperature of the slurry.

[0105] The controller is electrically connected to the heating element 700, and the controller is configured to control the heating temperature of the heating element 700 according to the temperature signal of the temperature detection element.

[0106] That is, the controller is electrically connected to the temperature sensor and each heating element 700. The controller can be a PLC controller, and the temperature detection element can be a temperature sensor. Both of them can be selected from existing products, and the model is not limited.

[0107] Exemplarily, a temperature sensor can be arranged in the material cavity 450 to detect the temperature of the asphalt in the material cavity 450 and send a temperature signal to the controller. Then, the controller can adjust the heating temperature of each heating member 700 according to the received temperature signal, optimize the heating effect on the asphalt, and ensure that the asphalt is always in an optimal flow state.

[0108] Correspondingly, a pressure sensor can also be arranged in the material cavity 450, and the pressure sensor can also be electrically connected to the pressurizing member 600 through a controller. The pressure in the material cavity 450 is detected by the pressure sensor, and then the pressure input into the material cavity 450 by the pressurizing member 600 is adjusted by the controller, so as to ensure that the asphalt is always in an optimal flow state.

[0109] In implementation, a high-frequency camera can also be added to the coating bin 412, so that the high-frequency camera can also be electrically connected to the driving member in the driving assembly 500 through a controller. Thus, the coating effect of the steel wire is detected by the visual recognition technology of the high-frequency camera, and then the rotation speed of the rotating support 220 is dynamically adjusted by the driving member, so as to realize the effect of self-adaptive coating. The high-frequency camera and the controller can be selected from existing products.

[0110] In some embodiments, a filtering member, which can be a filter screen, a filter layer or other structures, can also be added to the return pipe 440. The filtering member can filter the asphalt entering the slurry container 420 from the return tank, so as to reduce impurities in the reused asphalt and ensure the use quality of the subsequent asphalt.

[0111] In some embodiments, an explosion-proof valve and an emergency pressure relief device (such as a pressure relief valve) can also be installed on the feeding pipe 430, the return pipe 440 and the coating bin 412, so as to reduce the risk of asphalt leakage or explosion under high temperature and high pressure. The explosion-proof valve and the emergency pressure relief device can be selected from existing products.

[0112] A smell volatilizer can also be arranged in the return tank in the return bin 413, and when the slurry container 420 is an open structure, a smell volatilizer can also be arranged at the corresponding opening. The smell volatilizer can be selected from existing products. The smell volatilizer can condense and adsorb to reduce asphalt volatilization pollution.

[0113] In summary, the wire coating device provided by the embodiments of the present application can make the steel wires pass through the accommodation channels 300 respectively before being twisted and coated on the core layer, so that the rotating assembly 200 can support the rotation of the steel wires, and the steel wires can move relative to the accommodation channels 300 under the support of the rotating assembly 200.
