Description

Technical Field

[0001] This utility model relates to the field of shipbuilding and repair, and in particular to a shore power cable protection device for dual-fuel container ships. Background Technology

[0002] Shore power cables are specialized cables that connect a ship's shore power box to a power source on shore or on another vessel. They are mainly used in ports, docks, and other similar locations to provide power to berthed ships.

[0003] In current technologies, when shore power cables are towed after a ship docks, they typically rub against the cable guide holes or the outer side of the ship's railings. For large vessels like 21,000 TEU dual-fuel container ships, the required shore power cables are larger and heavier, making the friction issue even more pronounced during towing. This friction not only easily causes cable wear and damage but also further increases the risk of electrical accidents for the high-voltage power supply system unique to dual-fuel ships. Furthermore, the significant frictional resistance substantially increases the labor intensity of towing, reduces operational efficiency, and adversely affects the rapid shore power connection for these large vessels.

[0026] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0027] like Figures 1-5 As shown, the shore power cable protection device for dual-fuel container ships includes a supporting side frame 1; characterized in that it further includes:

[0028] The number of rolling components 2 is several, and the several rolling components 2 are installed at equal intervals along the length direction of the support side frame 1; the rolling component 2 includes multiple rolling rollers 201; the multiple rolling rollers 201 are distributed in a ring array around the inner side of the rolling component 2, and the multiple rolling rollers 201 in each rolling component 2 form a cable transmission channel.

[0029] The fastener 4 is located at the top of the support side frame 1 and is installed on the ship railing 5 of the dual-fuel container ship.

[0030] In practice, the shore power cable passes through all the cable transmission channels. When the shore power cable is dragged, it drives the rolling roller 201 in the rolling assembly 2 to roll, reducing the friction of the cable. This effectively prevents the shore power cable from being damaged by friction with the ship's hull when the ship docks, extends the service life of the shore power cable, and reduces electrical accidents.

[0031] like Figures 1-3As shown, there are two support side frames 1, and several rolling components 2 are installed between the two support side frames 1. The distance between the two support side frames 1 provides space for the installation of the rolling components 2.

[0032] like Figure 4 As shown, the rolling assembly 2 also includes two hollow frames 202; the two sides of the hollow frame 202 are fixedly connected to two support side frames 1, and the rolling roller 201 is installed on the hollow frame 202.

[0033] like Figure 4 As shown, a three-way pipe 203 is fixedly installed between the two hollow frames 202. A cavity is provided inside the hollow frame 202. The top and bottom ends of the three-way pipe 203 are connected to the cavities of the two hollow frames 202. The side end of the three-way pipe 203 passes through the supporting side frame 1 and extends to the outside of the supporting side frame 1.

[0034] like Figure 4 As shown, a sealing cap 3 is threaded onto the side port of the three-way pipe 203, and a ring of anti-slip texture is provided on the outer circumferential surface of the sealing cap 3.

[0035] like Figure 5 As shown, the rolling roller 201 includes a circular tube 2011, which is fixedly connected to a hollow frame 202 and communicates with the cavity inside the hollow frame 202. A cylinder 2016 is sleeved on the circular tube 2011, and a baffle 2015 is attached to both ends of the cylinder 2016 and fixedly sleeved onto the outer wall of the circular tube 2011. The shore power cable passes through the cable transmission channel, and the shore power cable rubs against the outer wall of the cylinder 2016, causing the cylinder 2016 to roll, thereby achieving rolling friction and reducing friction and wear.

[0036] like Figure 5 As shown, the outer wall of the cylindrical tube 2011 has a plurality of evenly distributed recesses 2012, and each recess 2012 is provided with a ball bearing 2014. The ball bearing 2014 causes rolling friction on the inner wall when the cylinder 2016 rotates, reducing wear on the inner wall.

[0037] The inner wall of the circular tube 2011 is provided with a plurality of connecting holes 2013, and the concave hole 2012 is connected to the inside of the circular tube 2011 through the connecting holes 2013.

[0038] In specific implementation, in order to further reduce the friction when the rolling roller 201 rotates, lubricating oil can be added for lubrication. The specific operation is as follows: by unscrewing the sealing cap 3, the side port of the three-way pipe 203 is opened. Through the oil injection structure, lubricating oil is injected into the side port of the three-way pipe 203. The lubricating oil enters the cavity of the hollow frame 202 through the three-way pipe 203, and then enters the round pipe 2011. Next, it enters the concave hole 2012 through the connecting hole 2013 to provide lubricating oil for the ball bearing 2014. When the cylinder 2016 rotates, it rubs against the ball bearing 2014 and is lubricated by the lubricating oil, reducing the wear of the cylinder 2016 during operation.

[0039] like Figures 2-3 As shown, the fixing component 4 includes a frame rod 401 and a pressure plate 404; a crossbar 402 is fixedly installed at both ends of the frame rod 401, and the two crossbars 402 and the frame rod 401 form a U-shaped structure. The ends of the two crossbars 402 away from the frame rod 401 are provided with external threads 403, and nuts 405 are threaded onto the external threads 403; two through holes are opened on the pressure plate 404, and the two crossbars 402 pass through the two through holes respectively, and the nuts 405 are pressed onto the pressure plate 404.

[0040] A sleeve 6 is fixedly installed on the top of the support side frame 1, and the crossbar 402 of the fixing member 4 passes through the sleeve hole on the sleeve 6.

[0041] The fastener 4 is used to fix the entire protective device to the horizontal tube of the ship railing 5. The specific installation operation is as follows: one horizontal bar 402 of the fastener 4 is passed through the sleeve hole of the sleeve 6, and then the U-shaped structure formed by the two horizontal bars 402 and the bracket 401 is fitted onto the horizontal tube of the ship railing 5. Then, the pressure plate 404 is placed on the two horizontal bars 402, specifically, the two horizontal bars 402 are respectively passed through the two through holes on the pressure plate 404. Then, the nut 405 is tightened on the external thread 403, so that the nut 405 presses the pressure plate 404, and the pressure plate 404 and the bracket 401 clamp the horizontal tube of the ship railing 5, thus completing the installation.

[0042] When removing the entire protective device from the horizontal tube of the ship railing 5, unscrew the nut 405, then remove the pressure plate 404, then separate the U-shaped structure from the horizontal tube of the ship railing 5, and then pull the U-shaped structure out of the sleeve 6 to complete the disassembly.

[0043] This utility model is not limited to the above-described embodiments. Any changes in its shape or structure fall within the protection scope of this utility model. The protection scope of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
