Implementation

[0017] The present invention can be further understood through the specific embodiments given below, but they are not intended to limit the present invention.

[0018] Embodiment 1: A shore power cable retracting and releasing device, comprising: a support frame 11, a current collector 12 arranged beside the support frame 11, and a wheel 6 rotatably mounted on the support frame 11, a reel 13 for winding a cable 3 is installed between two face-to-face arranged wheels 6, the reel 13 comprises: a coaxially sleeved inner cylinder 1 and an outer cylinder 2, the cable 3 is wound on the outer cylinder 2, the outer cylinder 2 is provided with a first winding groove 9 which is continuously distributed in a spiral shape on the outer surface of the inner cylinder 1, and the cable 3 wound on the outer surface of the outer cylinder 2 can be correspondingly embedded in the first winding groove In the groove 9, an outer shell 4 is coaxially arranged on the outer side of the outer cylinder 2, and a second winding groove 10 is spirally and continuously distributed on the inner surface of the outer shell 4 facing the outer cylinder 2. The second winding groove 10 for the cable 3 to be embedded is arranged corresponding to the first winding groove 9. The outer shell 4 is provided with an outlet 7 that passes through in the axial direction. A guide rail 20 is installed between the two wheels 6 and on the outer side of the outlet 7 on the drum 13. The guide rail 20 extends in a direction parallel to the axis of the drum 13, and a coating component for the cable 3 to pass through is slidably installed on the guide rail 20; When the cable is being rolled up or pulled out, in order to prevent the cable from being crossed, the cable is wound between the outer shell and the outer cylinder of the reel, so as to keep the cable wound on the reel normally and regularly; During the process of winding the cable between the outer shell and the outer cylinder of the drum, each time the cable wraps around the outer cylinder, the cable wraps around the first winding groove and the second winding groove until the cable is completely wound on the drum. The cable is in a spiral state on the drum, keeping the cable regularly placed on the drum.

[0019] The coating assembly comprises: a sleeve 16 arranged toward the outlet of the reel 13, the inner diameter of the sleeve 16 through which the cable 3 can pass is larger than the outer diameter of the cable 3, so that a cavity layer 161 is formed between the inner wall thereof and the cable 3, and the upper and lower surfaces of the sleeve 16 are respectively provided with a liquid inlet 171 and a liquid outlet 172 connected with the cavity layer 161; During the pulling process, the cable first passes through the coating assembly and is coated with anti-corrosion liquid under the action of the coating assembly, so that when the cable is exposed to the air, it is protected from seawater corrosion. The anti-corrosion liquid is evenly applied by injecting the anti-corrosion liquid into the sheath covering the entire circumference of the cable. Specifically: When the cable is pulled or reeled, the cable moves in the casing. Since a cavity layer is formed between the cable and the casing, the anti-corrosion liquid is introduced into the liquid inlet on the casing and coated on the surface of the cable. In order to avoid the existence of excess anti-corrosion liquid, the excess anti-corrosion liquid is sucked out through the liquid outlet on the casing and recycled again until the cable is completely pulled out. The surface of the cable exposed to the air is coated with the anti-corrosion liquid, which has an anti-corrosion effect.

[0020] The liquid inlet 171 and the liquid outlet 172 are both connected to a fluid tube 18. The fluid tube 18 on the liquid outlet 172 is connected to a liquid storage tank filled with preservative liquid. An elastic rubber ring 19 is installed at each end of the sleeve 16. The inner wall of each elastic rubber ring 19 is matched with the outer surface of the cable 3 with zero clearance.

[0021] The guide rail 20 is provided with a slide groove 201 for the sleeve 16 to be embedded in and a guide groove 202 for the liquid inlet 171 and the liquid outlet 172 to be embedded in. The slide groove 201 and the guide groove 202 each extend in a direction parallel to the axis of the reel 13.

[0022] Both ends of the guide rail 20 are mounted on the edge of the wheel disc 6 through a movable sleeve 21 that can move along the circumference of the wheel disc 6 .

[0023] A plurality of arc-shaped sliding sleeves 24 coaxially arranged with the reel 13 are arranged on the outside of the reel 13 and below the guide rail 20. An arc-shaped push plate 23 is arranged in each of the arc-shaped sliding sleeves 24. The lower end of the arc-shaped push plate 23 is embedded in the arc-shaped sliding sleeve 24 and slides with the inner wall of the arc-shaped sliding sleeve 24. The upper end of the arc-shaped push plate 23 is connected to the guide rail 20 through a buffer mechanism. A plurality of the arc-shaped push plates 23 are connected through a strip bracket 25. One end of an arc-shaped rack 261 coaxially arranged with the reel 13 is connected to the strip bracket 25. The other end of the arc-shaped rack 261 extends downward along the circumference of one arc-shaped push plate 23. A gear 262 meshing with the arc-shaped rack 261 is rotatably installed on the outside of the arc-shaped push plate 23. In order to avoid the phenomenon that the cable outlet becomes loose or broken due to the rise and fall of sea water, the effect of the arc push plate on the guide rail is controlled according to the ebb and flow of the sea surface, and the position of the guide rail on the wheel is adjusted by a sliding movable sleeve, thereby changing the tightness of the cable until the cable is adjusted to a normal power supply state by the guide rail, keeping the cable in a stable state. When the arc push plate pushes the guide rail to move upward, the cable is in a relaxed state, and when the arc push plate pushes the guide rail to move downward, the cable is in a tightened state.

[0024] The upper end of the arc-shaped push plate 23 coaxially arranged with the reel 13 has a hinged portion 231 extending in a direction away from the reel 13, and the buffer mechanism comprises: a plurality of connecting blocks 22 corresponding to the arc-shaped push plates 23, one end of each of the connecting blocks 22 is hingedly connected to the hinged portion 231 of the arc-shaped push plate 23, the other end of the connecting block 22 extends to the bottom of the guide rail 20, an axial body portion 291 of a pin passes upward through the connecting block 22 and is connected to the lower surface of the guide rail 20, a spring 30 is respectively installed on the axial body portion 291 and located above and below the connecting block 22, one of the springs 30 is located between the guide rail 20 and the connecting block 22, and the other spring 30 is located between the guide rail 20 and the cap body portion 292 at the lower end of the pin; When the arc-shaped push plate pushes the guide rail upward, the connecting block presses the spring above it to a compressed state, providing a buffering force for the guide rail connected to the connecting block when the sea tide rises and falls. Conversely, when the arc-shaped push plate pulls the guide rail downward, the connecting block presses the spring below it to a compressed state, providing a reverse buffering force for the guide rail connected to the connecting block, thereby adjusting the tightness of the cable and preventing the cable from being damaged due to rigid force.

[0025] Embodiment 2: A shore power cable retracting and releasing device, comprising: a support frame 11, a current collector 12 arranged beside the support frame 11, and a wheel 6 rotatably mounted on the support frame 11, a reel 13 for winding a cable 3 is installed between the two face-to-face arranged wheels 6, and the reel 13 comprises: an inner cylinder 1 and an outer cylinder 2 coaxially sleeved, the cable 3 is wound on the outer cylinder 2, and the outer cylinder 2 is provided with a first winding groove 9 which is continuously distributed in a spiral shape on the outer surface of the inner cylinder 1, and the cable 3 wound on the outer surface of the outer cylinder 2 can be correspondingly embedded in the first winding groove. In the groove 9, an outer shell 4 is coaxially arranged on the outer side of the outer cylinder 2, and a second winding groove 10 is spirally and continuously distributed on the inner surface of the outer shell 4 facing the outer cylinder 2. The second winding groove 10 for the cable 3 to be embedded is arranged corresponding to the first winding groove 9. The outer shell 4 is provided with an outlet 7 that passes through in the axial direction. A guide rail 20 is installed between the two wheels 6 and on the outer side of the outlet 7 on the drum 13. The guide rail 20 extends in a direction parallel to the axis of the drum 13, and a coating component for the cable 3 to pass through is slidably installed on the guide rail 20; Since the spirally wound cable moves from one end to the other end of the reel in the axial direction when it is pulled out from the reel or reeled back onto the reel, installing the coating assembly on the guide rail allows the coating assembly to move accordingly on the guide rail as the cable outlet direction moves, keeping the cable straight and not shaking when it is pulled, thereby maintaining the uniformity of the anti-corrosion liquid coating and effectively preventing seawater erosion during the cable power supply process.

[0026] The above-mentioned coating component includes: a sleeve 16 arranged toward the outlet of the reel 13, the inner diameter of the sleeve 16 for the cable 3 to pass through is larger than the outer diameter of the cable 3, so that a cavity layer 161 is formed between its inner wall and the cable 3, and the upper and lower surfaces of the sleeve 16 are respectively provided with a liquid inlet 171 and a liquid outlet 172 connected to the cavity layer 161.

[0027] The liquid inlet 171 and the liquid outlet 172 are both connected to a fluid pipe 18, and the fluid pipe 18 on the liquid outlet 172 is connected to a liquid storage tank filled with an antiseptic liquid. An elastic rubber ring 19 is installed at each end of the sleeve 16, and the inner wall of each elastic rubber ring 19 is matched with the outer surface of the cable 3 with zero clearance; When the cable moves on the sleeve, the elastic rubber rings at both ends are in contact with the cable, forming a closed cavity between the sleeve and the cable. When the anti-corrosion liquid is coated on the surface of the cable, as the cable moves, the elastic rubber ring can evenly spread the anti-corrosion liquid on the surface of the cable to avoid dripping on the cable.

[0028] The guide rail 20 is provided with a slide groove 201 for the sleeve 16 to be embedded in and a guide groove 202 for the liquid inlet 171 and the liquid outlet 172 to be embedded in. The slide groove 201 and the guide groove 202 each extend in a direction parallel to the axis of the reel 13.

[0029] Both ends of the guide rail 20 are mounted on the edge of the wheel disc 6 through a movable sleeve 21 that can move along the circumference of the wheel disc 6 .

[0030] A plurality of arc-shaped sliding sleeves 24 coaxially arranged with the reel 13 are arranged outside the reel 13 and below the guide rail 20. An arc-shaped push plate 23 is arranged in each of the arc-shaped sliding sleeves 24. The lower end of the arc-shaped push plate 23 is embedded in the arc-shaped sliding sleeve 24 and slides with the inner wall of the arc-shaped sliding sleeve 24. The upper end of the arc-shaped push plate 23 is connected to the guide rail 20 through a buffer mechanism. A plurality of the arc-shaped push plates 23 are connected by a strip bracket 25. One end of an arc-shaped rack 261 coaxially arranged with the reel 13 is connected to the strip bracket 25. The arc-shaped rack 261 is connected, and the other end of the arc-shaped rack 261 extends downward along the circumference of an arc-shaped push plate 23. A gear 262 meshing with the arc-shaped rack 261 is rotatably installed on the outer side of the arc-shaped push plate 23. In the process of the arc-shaped push plate driving the guide rail to move, since the arc-shaped push plate and the guide rail are connected through a buffer mechanism, when the tightness of the cable is adjusted by moving the guide rail, the buffer mechanism can effectively prevent the cable from being in a tight state in the casing after the position of the guide rail is adjusted, thereby reducing the shaking amplitude of the cable when the guide rail moves, and ensuring the stability of the cable.

[0031] The upper end of the arc-shaped push plate 23 coaxially arranged with the reel 13 has a hinged portion 231 extending in a direction away from the reel 13, and the buffer mechanism comprises: a plurality of connecting blocks 22 corresponding to the arc-shaped push plates 23, one end of each of the connecting blocks 22 is hingedly connected to the hinged portion 231 of the arc-shaped push plate 23, the other end of the connecting block 22 extends to the bottom of the guide rail 20, an axial body portion 291 of a pin passes upward through the connecting block 22 and is connected to the lower surface of the guide rail 20, a spring 30 is respectively installed on the axial body portion 291 and located above and below the connecting block 22, one of the springs 30 is located between the guide rail 20 and the connecting block 22, and the other spring 30 is located between the guide rail 20 and the cap body portion 292 at the lower end of the pin; When the arc-shaped push plate pushes the guide rail, the hinged part on the arc-shaped push plate is rotatably connected to one end of the connecting block, and the arc-shaped push plate indirectly pushes the guide rail through the connecting block, which can further provide buffering for the guide rail to prevent the cable in the casing from being subjected to excessive force instantaneously and causing large shaking, and facilitate disassembly and maintenance and replacement of various components.

[0032] The elastic rubber ring 19 is a rubber ring.

[0033] The fluid pipe 18 on the liquid outlet 172 is connected to a liquid storage tank.

[0034] A fluid pump is installed on the fluid pipe 18 connected to the liquid outlet 172 .

[0035] The first rotating shaft 15 passes through the coaxially arranged reel 13 and the wheel disc 6 from the axis and is rotatably mounted on the support frame 11. The two wheel discs 6 are each connected to the first rotating shaft 15 through a supporting plate 151. A first motor 14 is mounted on the support frame 11, and the output shaft of the first motor 14 is connected to one end of the first rotating shaft 15. When the ship is powered by retracting and releasing the cable, the cable is connected to the shore-based power supply system. When no power is supplied, the cable is stored and preserved, and the collector assists in power supply. When the cable is pulled, the cable is pulled out from the drum, and the first motor drives the wheel to rotate, thereby reeling in the pulled cable.

[0036] The lower end of the arc-shaped sliding sleeve 24 is fixedly mounted on the supporting frame 11 .

[0037] The 3 to 12 arc-shaped push plates 23 are arranged at equal intervals along the length direction of the bracket 20 .

[0038] The upper portion of the arc-shaped rack 261 is fixedly connected to the outer circumferential surface of an arc-shaped push plate 23 , and the lower portion of the arc-shaped rack 261 is slidably embedded in an arc-shaped sliding groove 241 provided on the corresponding arc-shaped sliding sleeve 24 .

[0039] The gear 262 is connected to the output shaft or the rotating handle of the second motor 28 via a second rotating shaft 27; When the arc-shaped rack is driven by the gear to move the arc-shaped push plate through the bar bracket, the second motor drives the gear to rotate, driving the arc-shaped rack meshing with the gear to slide in the arc-shaped sliding sleeve, and multiple arc-shaped push plates are fixedly connected to the same bar bracket, and one end of the arc-shaped rack is fixedly connected to the bar bracket. Therefore, the movement of the arc-shaped rack drives the movement of the bar bracket, so that the arc-shaped push plate can move around the wheel disc under the control of the arc-shaped rack, thereby completing the adjustment of the height position of the guide rail.

[0040] The gear 262 and the second motor 28 are both mounted on the support frame 11 .

[0041] The inner cylinder 1 and the outer cylinder 2 are connected via a plurality of support ribs 5 spaced apart along the circumferential direction.

[0042] A supporting base 8 is disposed at the bottom of the outer shell 4 .

[0043] The working principle of the present invention is as follows: When the ship is powered by retracting the cable, the cable is connected to the shore-based power supply system. When no power is supplied, the cable is stored and preserved, and the collector assists in power supply. When the cable is pulled, the cable is pulled out from the drum, and the first motor drives the wheel to rotate, thereby reeling in the pulled cable. During the pulling process, the cable first passes through the coating assembly and is coated with anti-corrosion liquid under the action of the coating assembly, so that when the cable is exposed to the air, it is protected from seawater corrosion. The anti-corrosion liquid is evenly applied by injecting the anti-corrosion liquid into the sheath covering the entire circumference of the cable. Specifically: When the cable is pulled or rolled up, the cable moves in the casing. Since a cavity layer is formed between the cable and the casing, the anti-corrosion liquid is introduced into the liquid inlet on the casing, and the anti-corrosion liquid is coated on the surface of the cable. In order to avoid the existence of excess anti-corrosion liquid, the excess anti-corrosion liquid is sucked out through the liquid outlet on the casing and recycled again. After the cable is completely pulled out, the surface of the cable exposed to the air is coated with the anti-corrosion liquid, which has an anti-corrosion effect. Furthermore, when the cable moves on the sleeve, the elastic rubber rings at both ends are in contact with the cable, so that a closed cavity is formed between the sleeve and the cable. When the anti-corrosion liquid is applied to the surface of the cable, the elastic rubber ring can evenly apply the anti-corrosion liquid to the surface of the cable as the cable moves, thereby avoiding the phenomenon of dripping on the cable. When the spirally wound cable is pulled out from the drum or reeled back onto the drum, it moves from one end to the other end in the axial direction of the drum. Installing the coating assembly on the guide rail allows the coating assembly to move on the guide rail in the direction of the cable outlet, keeping the cable straight and not shaking when it is pulled, thereby maintaining the uniformity of the anti-corrosion liquid coating and effectively preventing seawater erosion during the power supply process of the cable. In order to avoid the phenomenon that the cable outlet is loose or broken due to the rise and fall of sea water, the effect of the arc push plate on the guide rail is controlled according to the ebb and flow of the sea surface, and the position of the guide rail on the wheel is adjusted by the slidable movable sleeve, so as to change the tightness of the cable until the cable is adjusted to the normal power supply state by the guide rail, so as to keep the cable in a stable state. When the arc push plate pushes the guide rail to move upward, the cable is in a relaxed state, and when the arc push plate pushes the guide rail to move downward, the cable is in a tightened state. In the process of the arc-shaped push plate driving the guide rail to move, since the arc-shaped push plate and the guide rail are connected by a buffer mechanism, when the tightness of the cable is adjusted by moving the guide rail, the buffer mechanism can effectively prevent the cable from being in a tight state in the casing after the guide rail position is adjusted, thereby reducing the amplitude of the cable shaking when the guide rail moves and ensuring the stability of the cable; When the arc-shaped push plate pushes the guide rail, the hinged part on the arc-shaped push plate is rotatably connected with one end of the connecting block, and the arc-shaped push plate indirectly pushes the guide rail through the connecting block, which can further provide buffering for the guide rail to prevent the cable in the casing from being subjected to excessive force and causing large shaking, and facilitate disassembly and maintenance and replacement of various components; When the arc-shaped push plate pushes the guide rail upward, the connection block presses the spring above it to a compressed state, providing a buffer force for the guide rail connected to the connection block when the sea tide rises and falls. Conversely, when the arc-shaped push plate pulls the guide rail downward, the connection block presses the spring below it to a compressed state, providing a reverse buffer force for the guide rail connected to the connection block, while adjusting the tightness of the cable, avoiding damage to the cable due to rigid force; When the arc-shaped rack is driven by the gear and drives the arc-shaped push plate to move through the bar-shaped bracket, the second motor drives the gear to rotate, driving the arc-shaped rack meshing with the gear to slide in the arc-shaped sliding sleeve, and multiple arc-shaped push plates are fixedly connected to the same bar-shaped bracket, and one end of the arc-shaped rack is fixedly connected to the bar-shaped bracket. Therefore, the movement of the arc-shaped rack drives the movement of the bar-shaped bracket, so that the arc-shaped push plate can move around the wheel disc under the control of the arc-shaped rack, thereby completing the adjustment of the height position of the guide rail; When the cable is being rolled up or pulled out, in order to prevent the cable from being crossed, the cable is wound between the outer shell and the outer cylinder of the reel, so as to keep the cable wound on the reel normally and regularly; During the process of winding the cable between the outer shell and the outer cylinder of the drum, each time the cable wraps around the outer cylinder, the cable wraps around the first winding groove and the second winding groove until the cable is completely wound on the drum. The cable is in a spiral state on the drum, keeping the cable regularly placed on the drum.

[0044] When the above-mentioned shore power cable retracting and releasing device is used, it can not only effectively shield and protect the cable wound thereon to prevent the cable from being corroded and damaged due to long-term exposure to a complex environment, but also ensure the consistency and stability of the cable path during the release and reeling process, facilitate the control of the speed of reeling and releasing, and effectively avoid the situation where the cables are stacked and twisted. It can also keep the cable horizontal and output perpendicular to the axis direction of the reel at all times, avoid damage caused by bending of the cable, and improve the uniformity and stability of the coating. Furthermore, the anti-corrosion liquid is injected into the cavity layer distributed along the entire circumference of the outer side of the cable through the liquid inlet, so as to achieve the coating of the anti-corrosion liquid on the surface of the cable passing through the casing, and the entire surface of the cable can be evenly coated and the stability of the anti-corrosion liquid adhering to the surface of the cable can be ensured; In addition, by adjusting the position of the bracket, the height and tightness of the cable transmitted outward through the support tube on the bracket can be adapted to the rise and fall of the tide, and damage to the cable, especially the area located in the support tube, caused by instantaneous rigid force can be avoided.
