Technical Field

[0001] The invention relates to the technical field of electric power facilities, and in particular to a cable docking device used in special environments. Background Art

[0002] With the increasing demand for energy and the call for energy conservation and emission reduction, nuclear power generation is receiving widespread attention and application, and nuclear power ships have also emerged. In polar regions, the climate is harsh and conventional energy supply is difficult. Nuclear power ships can provide electricity and heat for scientific research stations and polar resource development projects. Therefore, in the process of power transmission between nuclear power ships and shore, it is necessary to ensure continuous, stable and high-power output, and also face severe environments. The laying of cables requires safe and reliable channels.

[0003] There are some problems with the common cable channels at present. For example, they cannot withstand low temperatures, which greatly reduces the efficiency of cable transportation; they cannot be disassembled and cannot be recycled; the connection between the ship and the shore is improper. When the ship rolls, the cable channel cannot rotate and cause damage to the channel.

[0004] Therefore, we propose a cable docking device for use in special environments to solve the above-mentioned problems. Summary of the invention

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Example 1

[0035] See also Figure 1-9 A cable docking device for special environments includes a hull 1, a dock berth 8 is arranged on the other side of the hull 1, a shore base 3 is installed on the top of the dock berth 8, a shore base pin 6 is arranged on the top of the shore base 3, a cable channel body 2 is arranged on the top of the shore base pin 6, the cable channel body 2 is made of D40 low-temperature resistant steel, the cable channel body 2 adopts a plate frame structure, which ensures that the structure can withstand the weight of the cable while also withstanding the low-temperature ice and snow environment, the inner cavity of the cable channel body 2 is provided with a supporting structure, a ship base 4 is installed on the hull 1, and a ship base pin 5 is installed on the top of the ship base 4, modular design, simple installation and disassembly: the overall cable channel is composed of various modules, and each module can be disassembled and replaced separately, with low installation and maintenance costs, a cable bracket 11 is installed at the bottom of the cable channel body 2 near the other side, and the cable bracket 11 and the top of the cable channel body 2 are jointly installed with a fixed base 9, and a support box 13 is jointly fixedly installed on the opposite side of the inner cavity of the cable channel body 2, and the inner cavity of the support box 13 is provided with a protective component.

[0036] The cable channel body 2, the shore base 3 and the ship base 4 are all made of high-strength low-temperature resistant steel and have good low-temperature resistance and strength.

[0037] Example 2

[0038] The supporting structure includes a plurality of auxiliary brackets 12 , and the auxiliary brackets 12 are fixedly installed in the inner cavity of the cable channel body 2 at equal intervals. The auxiliary brackets 12 are made of insulating material, which can prevent short circuits between the cables and the cable channel body 2 .

[0039] Specifically, the auxiliary bracket 12 can be used to support the cable, and by distributing the auxiliary bracket 12 equidistantly in the inner cavity of the cable channel 2, when supporting the cable, several auxiliary brackets 12 are evenly stressed, which can prevent the auxiliary bracket 12 from being damaged due to supporting excessively heavy cables, thereby extending the service life of the auxiliary bracket 12.

[0040] Example 3

[0041] The cable channel body 2 is connected to the shore base 3 by a pin shaft. When the nuclear power ship rolls due to wind and waves, the ship end part of the cable channel body 2 can slide smoothly on the shore base 3 along a preset trajectory, effectively dispersing and absorbing the stress and impact force generated by the movement of the hull, thereby protecting the cable channel body 2 from damage.

[0042] Specifically, the onshore base 3 is designed with a corresponding sliding adaptation structure, and the onboard base 4 is designed with a corresponding rotation adaptation structure to ensure that during the movement of the hull, the connection between the cable channel body 2 and the onshore base 3 always remains stable and does not affect power transmission.

[0043] A plurality of steel grilles 7 are fixedly mounted on the inner cavity side walls of the cable channel body 2 .

[0044] Specifically, the outer periphery of the steel grating 7 is coated with an anti-corrosion coating to prevent seawater erosion, thereby extending the service life of the steel grating 7 and reducing the cost of replacing the steel grating 7 .

[0045] The surfaces of the cable channel body 2, the shore base 3, the ship base 4 and the cable bracket 11 are all coated with an anti-corrosion coating, which can not only effectively resist seawater erosion, but also maintain excellent adhesion and anti-corrosion properties under low temperature conditions, thereby extending the service life of the equipment.

[0046] Specifically, four high-performance low-temperature-resistant main cables are integrated inside the cable channel body 2, so the cables can withstand low temperatures and will not significantly reduce the efficiency of cable transportation. These cables are made of special materials and can maintain excellent electrical performance and mechanical strength under extremely cold conditions, ensuring that the high-power electricity generated by the nuclear power ship can be stably and efficiently transmitted to the shore. This design not only improves the reliability of power transmission, but also meets the high standards for energy supply in polar regions. The cable channel body 2, support structure, shore base 3 and ship base 4 are all modularly designed to facilitate rapid on-site installation and subsequent maintenance. When some components are damaged or need to be upgraded, they can be replaced individually without affecting the overall operation, greatly reducing maintenance costs and downtime.

[0047] Example 4

[0048] The protection component includes a knocking motor 14 fixedly installed at the bottom of the inner cavity of the support box 13 and a cam 15 fixedly installed at the end of the power output shaft of the knocking motor 14. A plurality of round rods 17 are rotatably connected together at both sides of the inner cavity of the support box 13. A torsion spring 18 is sleeved on the outer periphery of the front round rod 17, and the two ends of the torsion spring 18 are respectively fixedly connected to the inner cavity side wall of the support box 13 and the adjacent round rod 17. A swing plate 16 is fixedly sleeved on the outer periphery of the round rod 17. A hinged rod 19 is hinged on the opposite side of two adjacent swing plates 16, and a plurality of knocking rods 10 are fixedly installed on the top of the swing plate 16.

[0049] Specifically, when the power output shaft of the knocking motor 14 rotates, the cam 15 fixed on the shaft end of the power output shaft of the knocking motor 14 can rotate, and then the swing plates 16 can swing with the cooperation of adjacent hinged rods 19 and torsion springs 18, and then the knocking rods 10 fixed on the swing plates 16 can swing back and forth, which can knock on the cable and remove snow and ice from its surface, thereby preventing the cable from being broken by accumulated snow, and thus extending the service life of the cable.

[0050] Working principle: When the present invention is actually used, when the ship is rigidly moored at the dock berth 8, if the relative positions of the two ends of the channel change, the axial hole on the hull base 3 can constrain the horizontal freedom of the hull 1 end in two directions, so that it only moves and changes its angle in the vertical direction; the shore base 3 is provided with an oblong hole parallel to the long side of the channel, which can constrain the horizontal freedom of the shore base end of the channel perpendicular to the long side of the channel, so that it moves and changes its angle in the vertical direction, and only moves along the oblong hole, thereby ensuring that the functional requirements of the channel are met under the design conditions. When the nuclear power ship rolls due to wind and waves, the ship end part of the cable channel body 2 can slide smoothly on the shore base 3 along the preset trajectory, effectively dispersing and absorbing the stress and impact force generated by the movement of the hull, thereby protecting the cable channel body 2 from damage. At the same time, the shore base 3 is designed with a corresponding sliding adaptation structure, and the ship base 4 is designed with a corresponding rotation adaptation structure to ensure that during the movement of the hull 1, the connection between the cable channel body 2 and the shore base 3 always remains stable and does not affect power transmission. In addition, when it is necessary to remove snow from the cable, the cam 15 fixed to the shaft end of the power output shaft of the knocking motor 14 can rotate when the power output shaft of the knocking motor 14 rotates, so that the swing plate 16 can swing with the cooperation of the adjacent hinged rod 19 and the torsion spring 18, and then the knocking rod 10 fixed on the swing plate 16 can swing back and forth, which can knock on the cable and remove snow and ice from its surface, thereby preventing the cable from being broken by the accumulated snow, thereby extending the service life of the cable.
