Description

Technical Field

[0001] The present invention relates to the technical field of vibration-suppressing streamers, and particularly relates to an integrated structure of a streamer and a towing cable and a processing device thereof. Background Art

[0002] Marine exploration equipment usually uses a towing cable to connect with the hull for data transmission and underwater towing movement. Ordinary towing cables have a circular cross-section. When using an ordinary towing cable for towing operations, vortices that detach from the surface of the structure will alternately generate on both sides of the towing cable, forming periodic vortex-induced vibrations. If the vortex shedding frequency is close to the natural frequency of the towing cable, the towing cable will vibrate significantly. Continuous vortex-induced vibrations will not only cause structural fatigue damage, shorten the structural life, and break the towing cable, but the noise generated during vibration will also affect the accuracy of the data of the exploration equipment. Most of the towing cables that suppress vortex-induced vibrations are hair cables. Such a towing cable regularly picks out braided tapes during weaving and uses the picked-out "hair"-like braided tapes to suppress vibrations. The appearance of this kind of towing cable is rough, the drag is large during towing, and the ability to suppress vortex-induced vibrations is poor.

[0003] The streamer towing cable with an integrated structure of a streamer and a towing cable can block the conversion of the confluence point in the wake area generated during the towing operation of the towing cable. When producing an integrated streamer towing cable structure, an injection molding machine is required to realize the injection connection of the streamer and the towing cable.

[0004] Currently, there is a lack of automated production equipment to handle the production of the integrated streamer towing cable structure. It is necessary to cooperate with an injection molding machine manually. The streamer pieces are placed flat in the injection molding machine mold manually, and then the injection molding machine is controlled to close and open the mold, and the operation is repeated to perform injection connection at intervals on the towing cable, which seriously slows down the production efficiency. Therefore, a device that can cooperate with the injection molding machine to realize the automated and batch production of the integrated streamer towing cable structure is needed to solve the current problems. Summary of the Invention

[0005] The present invention aims at the above problems and provides an integrated structure of a streamer and a towing cable, including a towing cable and a net-covered streamer piece. The outer diameter of the towing cable is 30 ± 0.5 mm, the density of the towing cable is 2.20 ± 0.10 g / cm³. The net-covered streamer piece is composed of a bare streamer piece with a grid cloth covered on both sides. The width of the bare streamer piece is 4 times the outer diameter of the towing cable, the width of the grid cloth is 4 times the outer diameter of the towing cable + one-third of the circumference of the towing cable. The length of the net-covered streamer piece is the same as the length of the towing cable. The thickness of the net-covered streamer piece is 1 mm, the grid width of the grid cloth is 3 mm. After installing the net-covered streamer piece, the outer diameter of the towing cable is not greater than 32 mm, and the total density of the towing cable + streamer is 2.00 ± 0.10 g / cm³.

[0012] The beneficial effects of the present invention are as follows: (1) The integrated ribbon tow cable of the present invention can block the conversion of the wake area confluence point generated during the tow cable towing operation, suppress the vortex shedding or delay it to a farther downstream area to reduce the vibration of the tow cable, thereby effectively suppressing the transmission of additional noise to the marine detection equipment. When the tow cable with the ribbon is performing the towing operation, the pulsating force of the vortices that alternately separate from the surface of the structure on both sides of the tow cable is postponed to a farther downstream area by the ribbon pieces, greatly reducing the vibration of the tow cable. This not only makes the data collected by the marine monitoring equipment more accurate but also improves the service life of the tow cable.

[0013] (2) The present invention intermittently conveys a tow cable of a rated length through a positioning and conveying mechanism. The tow cable is located inside the mold. The ribbon pieces are intermittently conveyed into the mold through a ribbon conveying mechanism. The ribbon pieces inside the mold are combined with the tow cable. The ribbon pieces inside the mold are flattened by a flattening mechanism to make them flat and prevent them from wrinkling. Then, injection molding is carried out by an injection molding machine, so that the tow cable and the ribbon pieces are stably connected. Through the above three mechanisms, the continuous automatic production of the integrated structure of the tow cable and the ribbon is realized, the production efficiency of the integrated structure of the tow cable and the ribbon is improved. The present invention has strong integrity and high automation degree, and the labor intensity can be effectively reduced during the production process, realizing high-quality and high-efficiency production operations.

[0014] (3) In the present invention, the ribbon pieces are placed in a storage box of appropriate size. The first cylinder drives the moving frame to move forward, and the sliding frame, the two ejector pins and the sliding column move forward synchronously. The sliding column moves downward due to the action of the pressing rod, so that the sliding frame and the ejector pins move downward. When at the end of the conveyor belt group, the two downward-moving ejector pins are inserted into the ribbon pieces in the storage box and carry the ribbon pieces forward into the mold until the ribbon pieces are placed in the grooves inside the mold. Then, the first cylinder retracts, the inclined ejector pins retract and rotate slightly, and relative sliding occurs with the ribbon pieces. The retracted ejector pins will not damage the ribbon pieces. Through the above components, the automatic feeding operation of the ribbon pieces into the mold is realized.

[0015] (4) In the present invention, through the movement of the connecting frame, components such as the connecting plate, the dial block, and the flattening roller move into the mold, so that the dial block and the flattening roller are located above the ribbon pieces inside the mold. The motor drives the screw rod to rotate, which, in cooperation with the guide rod, causes the connecting plate to move downward. The connecting plate drives the dial block and the flattening roller to move downward. The lower side of the dial block presses tightly on the ribbon pieces. As the connecting plate continues to move downward, the dial block moves relatively upward. The dial block acts on the two side lever arms, causing the two side lever arms to separate and tilt. After the connecting plate continues to move downward, the two side lever arms open towards both sides, and further cause the flattening roller to move from the middle to both sides. This movement process acts on the ribbon pieces inside the mold to make them flat and prevent them from wrinkling, which affects the bonding quality with the tow cable and the vibration damping effect.

[0016] (5) In the present invention, the rotary cylinder drives the rotating shaft. First, the rotating shaft drives the two telescopic shafts on both sides to rotate through a bevel gear set. The telescopic shafts drive the connecting shaft to rotate through a bevel gear set. Through multiple sets of transmissions, the two rotating clamps on both sides move synchronously. The spring splints on both sides of the rotating clamp approach each other to clamp both sides of the tow cable. Then, the rotary cylinder continues to rotate. At this time, the springs on the spring splints are further compressed. The incomplete gear meshes with the first racks on both sides and drives the first racks on both sides to move, causing the two clamping arms to move away from each other, and the telescopic shafts extend. The above steps realize clamping the tow cable first, and then the two clamping arms move towards both sides, and the clamps on both sides pull the tow cable towards both sides, making the tow cable in a tensioned state, further improving the injection molding bonding effect and the quality of the integrated structure of the ribbon and the tow cable.

[0033] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0034] As Figure 1 and Figure 2 shown, an integrated structure of a ribbon and a tow cable includes a tow cable 1 and a net-covered ribbon piece 3. The outer diameter of the tow cable 1 is 30 ± 0.5 mm, the density of the tow cable 1 is 2.20 ± 0.10 g / cm³. The net-covered ribbon piece 3 is composed of a bare ribbon piece 31 with a grid cloth 32 wrapped on both sides. The width of the bare ribbon piece 31 is 4 times the outer diameter of the tow cable 1, the width of the grid cloth 32 is 4 times the outer diameter of the tow cable 1 plus one-third of the tow cable circumference. The length of the net-covered ribbon piece 3 is the same as the length of the tow cable 1. The thickness of the net-covered ribbon piece 3 is 1 mm, the grid width of the grid cloth 32 is 3 mm. After installing the net-covered ribbon piece, the outer diameter of the tow cable is not greater than 32 mm, and the total density of the tow cable + ribbon is 2.00 ± 0.10 g / cm³.

[0035] In the above embodiments, the ribbon tow cable 1 of the integrated structure can block the conversion of the wake area confluence point generated during the towing operation of the tow cable 1, suppress the vortex shedding or delay it to a farther downstream area to reduce the vibration of the tow cable 1, thereby effectively suppressing the transmission of additional noise to the marine exploration equipment. When the tow cable 1 with the ribbon installed is performing a towing operation, the pulsating force of the vortices that alternately separate from the surface of the structure on both sides of the tow cable 1 is delayed to a farther downstream area by the ribbon piece, greatly reducing the vibration of the tow cable 1. This not only makes the data collected by the marine monitoring equipment more accurate, but also improves the service life of the tow cable 1; To obtain the specific vibration suppression efficiency data of the ribbon tow cable 1, the ribbon tow cable 1 and the tow cable 1 without the ribbon were respectively used for towing operations (sea trials) at different angles, and the vibration suppression efficiency of the ribbon tow cable 1 was calculated by comparing the experimental results. The experimental data are shown in the following table: Table 1. Ribbon Tow Cable Vibration Suppression Efficiency

[0036] As Figure 3 and Figure 4 shown, the present invention also provides a processing device for an integrated structure of a ribbon and a tow cable. The connection between the ribbon and the tow cable is realized by an injection molding method, and it includes a frame 4, a vertical injection molding machine 5, a ribbon conveying mechanism 6, a flattening mechanism 7, and a positioning and conveying mechanism 8. The vertical injection molding machine 5 is connected to the middle of the frame 4, and the mold of the vertical injection molding machine 5 is suitable for the injection molding operation of the ribbon piece and the tow cable 1. The ribbon conveying mechanism 6 is connected to the upper side of the frame 4, and the ribbon conveying mechanism 6 is used for continuously conveying the ribbon piece. The flattening mechanism 7 is connected to the upper side of the frame 4, and the flattening mechanism 7 acts on the ribbon piece in the mold to make it flat. The flattening mechanism 7 is linked with the ribbon conveying mechanism 6. The positioning and conveying mechanism 8 is connected to the upper side of the frame 4, and the positioning and conveying mechanism 8 is used for intermittently conveying the tow cable 1 of a rated length.

[0037] In the above embodiments, the tow cable 1 of a rated length is intermittently conveyed by the positioning and conveying mechanism 8, and the tow cable 1 is located inside the mold. The ribbon piece is intermittently conveyed into the mold by the ribbon conveying mechanism 6. The ribbon piece in the mold is combined with the tow cable 1. The flattening mechanism 7 acts on the ribbon piece in the mold to make it flat and prevent it from wrinkling. Then, injection molding is carried out by the injection molding machine, so that the tow cable 1 and the ribbon piece are stably connected. The continuous automatic production of the integrated structure of the tow cable 1 and the ribbon is realized through the above three mechanisms, which improves the production efficiency of the integrated structure of the tow cable 1 and the ribbon. The present invention has strong integrity and high automation degree, and the labor intensity can be effectively reduced during the production process, realizing high-quality and high-efficiency production operations.

[0038] Specifically, as Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8As shown in the figure, the ribbon conveying mechanism 6 includes a conveyor belt group 61, a storage box 62, a first cylinder 63, a moving frame 64, a sliding frame 65, two ejector pins 66, two pressing rods 67 and a sliding column 68. The conveyor belt group 61 is connected to the upper side of the frame 4. The storage box 62 is connected to the conveyor belt group 61. One side of the storage box 62 is provided with an opening. The size of the storage box 62 is adapted to the ribbon piece. The first cylinder 63 is connected directly above the conveyor belt group 61. The moving frame 64 is slidably connected to the frame 4. The moving frame 64 is fixedly connected to the output shaft of the first cylinder 63. The sliding frame 65 is slidably connected to the moving frame 64 in the vertical direction. A spring for resetting is connected to the sliding frame 65. The two ejector pins 66 are respectively rotatably connected to both sides of the sliding frame 65. A torsion spring is connected to the rotating connection of the ejector pin 66. The ejector pin 66 is inclined. The ejector pin 66 is used to move the ribbon piece from the storage box 62 into the mold. The two pressing rods 67 are respectively connected to both sides of the conveyor belt group 61. The pressing rods 67 are arranged at different heights. Sliding columns 68 are respectively connected to both sides of the sliding frame 65. The pressing rods 67 cooperate with the sliding columns 68.

[0039] In the above embodiments, the ribbon piece is placed in the storage box 62 with a suitable size. The first cylinder 63 drives the moving frame 64 to move forward. The sliding frame 65, the two ejector pins 66 and the sliding columns 68 move forward synchronously. The sliding columns 68 move downward due to the action of the pressing rods 67, so that the sliding frame 65 and the ejector pins 66 move downward. When at the end of the conveyor belt group 61, the two downward-moving ejector pins 66 are inserted into the ribbon piece in the storage box 62 and carry the ribbon piece forward into the mold until the ribbon piece is placed in the groove in the mold. Then the first cylinder 63 retracts. The inclined ejector pins 66 retract and rotate slightly, sliding relative to the ribbon piece. The retracting ejector pins 66 will not damage the ribbon piece. Through the above components, the automatic feeding operation of the ribbon piece into the mold is realized.

[0040] Specifically, such as Figure 3 、 Figure 4 、 Figure 5 、 Figure 10 and Figure 11As shown in the figure, the flattening mechanism 7 includes a connecting frame 71, a connecting plate 72, a sliding rod 73, a dial block 74, a dial rod 76, a flattening roller 77, a motor 78, a lead screw 79 and a guide rod 710. The connecting frame 71 is slidably connected to the frame 4. The connecting plate 72 is slidably connected to the connecting frame 71 in the vertical direction. The sliding rod 73 slidably penetrates the end of the connecting plate 72. A spring is connected to the sliding rod 73. The dial block 74 is connected to the lower end of the sliding rod 73. Anti-slip protrusions 75 are provided on the lower side of the dial block 74. Two dial rods 76 are respectively hinged to both sides of the connecting plate 72. A torsion spring is connected to the hinge of the dial rod 76. When the dial block 74 moves upward relatively, the two dial rods 76 are separated. Two flattening rollers 77 correspond to the dial rods 76. The flattening roller 77 is rotatably connected to the lower end of the dial rod 76. The flattening roller 77 acts on the ribbon piece. The motor 78 is connected to the connecting frame 71. The lead screw 79 is rotatably connected to the connecting frame 71. The lead screw 79 is fixedly connected to the output shaft of the motor 78. The lead screw 79 penetrates the connecting plate 72. The lead screw 79 is in threaded cooperation with the connecting plate 72. The guide rod 710 is connected to the connecting frame 71. The guide rod 710 slidably penetrates the connecting plate 72.

[0041] In the above embodiments, through the movement of the connecting frame 71, components such as the connecting plate 72, the dial block 74, and the flattening roller 77 move into the mold, so that the dial block 74 and the flattening roller 77 are located above the ribbon piece in the mold. The motor 78 drives the lead screw 79 to rotate. In cooperation with the guide rod 710, the connecting plate 72 moves downward. The connecting plate 72 drives the dial block 74 and the flattening roller 77 to move downward. The lower side of the dial block 74 is pressed tightly against the ribbon piece. When the connecting plate 72 continues to move downward, the dial block 74 moves upward relatively. The dial block 74 acts on the two dial rods 76 on both sides, causing the two dial rods 76 on both sides to separate and tilt. After the connecting plate 72 continues to move downward, the two dial rods 76 open toward both sides. As a result, the flattening roller 77 moves from the middle to both sides. This movement process acts on the ribbon piece in the mold, making it flat and preventing it from wrinkling, which affects the bonding quality with the tow cable 1 and the vibration suppression effect.

[0042] Specifically, such as Figure 3 、 Figure 4 、 Figure 12 、 Figure 13 、 Figure 14 and Figure 15As shown in the figure, the positioning and conveying mechanism 8 includes a positioning frame 81, a second cylinder 82, clamping arms 83, two rotary clamps 84, spring splints 85, a rotating shaft 86, two telescopic shafts 87, an incomplete gear 810, two first racks 811 and a rotary cylinder 812. The positioning frame 81 is horizontally slidably connected to the frame 4. The second cylinder 82 is connected to the frame 4, and the output shaft of the second cylinder 82 is fixedly connected to the positioning frame 81. Clamping arms 83 are slidably connected to both sides of the positioning frame 81. The two rotary clamps 84 correspond to the clamping arms 83. The rotary clamps 84 are connected to the upper ends of the corresponding clamping arms 83. Spring splints 85 are connected to both sides of the rotary clamps 84. The rotating shaft 86 is rotatably connected to the positioning frame 81. The two telescopic shafts 87 correspond to the clamping arms 83. The telescopic shafts 87 are linked with the rotating shaft 86 through bevel gear sets 88. The telescopic shafts 87 are linked with the corresponding rotary clamps 84 through bevel gear sets 88 and connecting shafts 89. The incomplete gear 810 is coaxially connected to the rotating shaft 86. The two first racks 811 are respectively and correspondingly connected to the clamping arms 83. The two first racks 811 are respectively located on both sides of the incomplete gear 810. The first racks 811 cooperate with the incomplete gear 810. The rotary cylinder 812 is connected to the positioning frame 81, and the output end of the rotary cylinder 812 is fixedly connected to the rotating shaft 86.

[0043] In the above embodiments, the rotary cylinder 812 drives the rotating shaft 86. First, the rotating shaft 86 drives the two telescopic shafts 87 on both sides to rotate through the bevel gear sets 88. The telescopic shafts 87 drive the connecting shafts 89 to rotate through the bevel gear sets 88. Through multiple sets of transmissions, the two rotary clamps 84 on both sides move synchronously. The spring splints 85 on both sides of the rotary clamps 84 approach each other to clamp both sides of the tow cable 1. Then the rotary cylinder 812 continues to rotate. At this time, the springs on the spring splints 85 are further compressed. The incomplete gear 810 starts to mesh with the two first racks 811 on both sides, driving the two first racks 811 to move, so that the two clamping arms 83 move away from each other, and the telescopic shafts 87 extend. The above steps realize clamping the tow cable 1 first, and then the two clamping arms 83 move to both sides, and the clamps on both sides pull the tow cable 1 to both sides, so that the tow cable 1 is in a tensioned state, further improving the injection molding bonding effect and the quality of the integrated structure of the ribbon tow cable 1.

[0044] Specifically, as Figure 8 and Figure 9As shown in the figure, it further includes two telescopic rods 9, a limit plate 10, a first magnet 11, a second magnet 12, a first limit block 13 and a second limit block 14. The two telescopic rods 9 correspond to the pressing rod 67. The telescopic rods 9 are slidably connected inside the pressing rod 67. The limit plate 10 is fixedly connected to the end of the telescopic rod 9. The first magnet 11 is embedded in the limit plate 10. The second magnet 12 is embedded in the sliding column 68. The first magnet 11 cooperates with the second magnet 12. When the telescopic rod 9 extends, it enters the mold to provide guiding and limiting effects for the sliding column 68. The first limit block 13 is connected to the rotating connection of the ejector pin 66. The second limit block 14 is connected to the sliding frame 65. The first limit block 13 cooperates with the second limit block 14 to limit the rotation of the ejector pin 66.

[0045] In the above embodiments, when the ejector pin 66 advances into the mold with the ribbon piece, the sliding column 68 pushes the limit plate 10, so that the telescopic rod 9 extends out of the pressing rod 67. The first magnet 11 attracts the second magnet 12, and the telescopic rod 9 still provides guiding and limiting effects for the sliding column 68. When the conveyance of the ribbon piece is completed once, the telescopic rod 9 retracts to its original position with the ejector pin 66, facilitating the closing operation of the mold. The first limit block 13 cooperates with the second limit block 14, so that the ejector pin 66 can be prevented from rotating when advancing, stably driving the ribbon piece forward. When retracting, the ejector pin 66 can rotate within a small range to prevent the ribbon piece from being pulled backward and damaged. Then, due to the action of the torsion spring, the ejector pin 66 returns to its original position.

[0046] Specifically, as Figure 5 、 Figure 7 and Figure 10 shown in the figure, it further includes two second racks 15 and two third racks 16. The two second racks 15 are respectively connected to both sides of the connecting frame 71. The two third racks 16 are respectively connected to both sides of the moving frame 64. The second rack 15 is linked with the corresponding third rack 16 through a gear.

[0047] The working principle of the present invention is as follows: The connection between the towing cable 1 and the net-covered ribbon piece 3 is realized by injection molding. First, the equipment is preheated to the specified temperature. During this period, after adjusting the positions of the injection mold feeding port and the injection machine injection port to be consistent, the injection mold is fixed. After reaching the specified temperature, the material is fed and it is ensured that the material is full and can be injected; After that, the net-covered ribbon piece 3 is placed in the storage box 62 of the conveyor belt group 61. The conveyor belt group 61 runs intermittently. The first cylinder 63 pushes the moving frame 64 to advance. The moving frame 64 and the sliding frame 65 advance synchronously. The sliding column 68 on the sliding frame 65 abuts against the pressing rod 67. When the ejector pin 66 moves to the end of the conveyor belt group 61 along with the sliding frame 65, the pressing rod 67 acts on the sliding column 68 to make it move downward, and the ejector pin 66 moves downward and is inserted into the frontmost net-covered ribbon piece 3, and the two ejector pins 66 are at the outermost sides of the net-covered ribbon piece 3; The thimble 66 continues to move forward. During this process, the sliding column 68 runs to the end of the pressing rod 67. The sliding column 68 drives the limit plate 10, causing the telescopic rod 9 to extend from the pressing rod 67. The telescopic rod 9 moves into the mold and continues to provide guidance and downward pressure for the sliding column 68 until the net-covered ribbon piece 3 enters the groove of the mold. While the ribbon conveying mechanism 6 is moving, the smoothing mechanism 7 moves synchronously in linkage. The moving frame 64 moves forward to drive the second rack 15. The second rack 15 drives the third rack 16 through the gear, causing the connecting frame 71 and the moving frame 64 to move closer to each other. When the thimble 66 drives the net-covered ribbon piece 3 into the mold, the connecting frame 71 drives the connecting plate 72, the dial block 74, the dial rod 76, and the smoothing roller 77 to move to the upper side of the net-covered ribbon piece 3. Then the motor 78 runs to drive the lead screw 79 to rotate. Through the cooperation of the guide rod 710, the connecting plate 72 moves downward, driving the dial block 74 to move downward synchronously. When the dial block 74 abuts against the net-covered ribbon piece 3 and the anti-slip protrusion 75 on the lower side of the dial block 74 presses tightly against the net-covered ribbon piece 3, the dial block 74 moves upward relative to the connecting plate 72, and the spring is compressed. Then the dial block 74 pushes the two side dial rods 76, causing the two side dial rods 76 to separate. The smoothing roller 77 rolls on the net-covered ribbon piece 3 under the action of the torsion spring, acting on the net-covered ribbon piece 3 to make it flat. After the smoothing operation is completed, the motor 78 rotates in reverse, and components such as the dial block 74 and the dial rod 76 move upward. The first cylinder 63 retracts, and the ribbon conveying mechanism 6 and the smoothing mechanism 7 return to their original positions. When the thimble 66 retracts, the inclined thimble 66 can rotate within a small range and slide relative to the net-covered ribbon piece 3 to prevent the thimble 66 from pulling the net-covered ribbon piece 3. During the retraction process, the first magnet 11 attracts the second magnet 12, causing the telescopic rod 9 to return to its original position, facilitating the closing of the mold. Then the rotary cylinder 812 is operated to drive the rotating shaft 86 to rotate. The rotating shaft 86 drives the telescopic shaft 87 and the connecting shaft 89 to rotate through the bevel gear set 88, causing the two side rotary clamps 84 to move. The spring splints 85 on the rotary clamps 84 move closer to each other to clamp the towing cable 1. After clamping, the rotary cylinder 812 continues to rotate, and the spring on the spring splint 85 continues to be compressed. The incomplete gear 810 meshes with the two side first racks 811, driving the two side first racks 811 to move, causing the two side clamping arms 83 to move away from each other. At this time, the telescopic shaft 87 extends, and the two side rotary clamps 84 drive the towing cable 1, making the towing cable 1 in the mold in a tensioned state, improving its injection molding quality. Then the injection molding machine is operated to close the two side molds, enabling the towing cable 1 to be injection-molded and connected to the exposed mesh cloth 32 part of the net-covered ribbon piece 3. The injection molding material fully flows into the mold. After 15S, the injection molding machine automatically opens the mold. The first cylinder 63 pushes the positioning frame 81 forward by a rated distance, preparing for the next injection molding operation. Repeat the feeding of the net-covered ribbon piece 3 and the smoothing operation of the net-covered ribbon piece 3. Repeat the forward movement of the positioning frame to continuously injection-mold and connect the net-covered ribbon piece 3 to the towing cable 1. It should be noted that the device of the present invention also cooperates with an external traction mechanism and a winding mechanism to realize the pay-out and winding operations of the towing cable 1, and existing technologies can be used for both operations.

[0048] The above is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
