Description

Technical Field

[0001] The invention belongs to the technical field of marine cables, and in particular relates to an energy-saving self-cleaning suspended marine cable. Background Art

[0002] With the vigorous development of domestic tourism, a large number of islands in my country's coastal areas have been developed in large quantities. Before the development process, it is necessary to first transmit electricity to the islands, so it is necessary to connect cables from the inland to the islands. In order to save the cost of cable layout and facilitate the later maintenance of the cables, floating marine cables are often used, such as the patent application number in the prior art: CN201120062134.8, patent name: a floating cable, the marine cable has good flexibility and can float on the water surface. In addition, since the cable is arranged on the water surface, the cable can be well cooled, so the marine cable can achieve high-power power transmission to meet the power use of the islands. However, the problem in the prior art is that since the marine cable spans the strait between the island and the inland, when the ship chooses to directly pass through the cable through the strait, the propeller of the ship is easy to entangle the cable and damage the cable and propeller, and when the ship chooses to sail around the island, it is often necessary to increase the ship's sea mileage, so that the ship cannot choose the best sailing route, thereby increasing the sailing cost. Summary of the invention

[0003] The problem in the prior art that the present invention needs to solve is: since the marine cable spans the strait between the island and the inland, when a ship chooses to directly pass over the cable through the strait, the ship's propeller is likely to entangle the cable and cause damage to the cable and the propeller; and when the ship chooses to sail around the island, it is often necessary to increase the ship's sea mileage, making it impossible for the ship to choose the best sailing route, thereby increasing the sailing cost.

[0004] The technical solution adopted by the present invention is:

[0005] An energy-saving self-cleaning suspended marine cable comprises a gantry tube, a cable body, a cylinder body and a piston, both ends of the gantry tube are provided with floating seats, a plurality of support columns are slidably penetrated on the floating seats, the support columns are fixedly installed on the seabed, the cable body is arranged in the gantry tube, and sealing members are arranged between the cable body and both ends of the gantry tube, the cylinder body is installed on the upper surface of the floating seat, a water suction pipe and a drainage pipe 1 are arranged on the top of the cylinder body, a water suction one-way valve is arranged on the water suction pipe, and the water suction pipe extends below the sea level, a drainage one-way valve is arranged on the drainage pipe 1, and the drainage pipe 1 is connected to one end of the gantry tube, and a drainage pipe 2 is connected to the end of the gantry tube away from the drainage pipe 1, the piston is arranged in the cylinder body, a piston rod is arranged on the lower surface of the piston, the piston rod passes through the bottom of the cylinder body and is provided with a floating block 1.

[0006] Furthermore, the cable body has a foamed inner protective layer, an outer protective layer is provided on the outer surface of the foamed inner protective layer, and an anti-fouling coating is provided on the outer surface of the outer protective layer.

[0007] Furthermore, the floating seat includes a support seat 1, a floating block 2 is provided on a lower surface of the support seat, the support column is slidably passed through the support seat 1 and the floating block 2, the two ends of the gantry tube are respectively fixedly connected to the two support seats 1, and the end of the gantry tube extends on the lower surface of the floating block 2, and the ends of the drain pipe 1 and the drain pipe 2 both pass through the support seat 1 and the floating block 2 and are respectively connected to the two ends of the gantry tube.

[0008] Furthermore, a bracket is connected to the cylinder body, the bracket is installed on the upper surface of the support seat 1, the end of the piston rod is connected to the support seat 2, and the floating block 1 is installed on the lower surface of the support seat 2.

[0009] Furthermore, a communicating hole is provided at the bottom of the cylinder body.

[0010] Furthermore, the two ends of the drainage pipe are installed above the gantry pipe through a pipe rack.

[0011] Furthermore, solar lamps are installed on both sides of the gantry tube.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. When the tide changes, the sea level drives the floating seat to slide on the support column, and then drives the gantry tube to rise and fall to adjust the height of the gantry tube, which can effectively prevent the ship from hitting the top of the gantry tube when the tide rises, and at the same time can lower the setting height of the gantry tube, thereby improving the wind resistance of the gantry tube.

[0014] 2. Placing the cable body in the gantry tube can effectively prevent the acidic substances in bird droppings and pancreatic enzyme proteins from corroding the cable body. At the same time, the passage of ships through the gantry tube can prevent the propeller from entangled in the cable and causing damage to the cable and propeller, which is conducive to the ship's selection of the best route. It can protect the cable body and reduce the cost of navigation. The floating block is used to drive the piston to slide up and down in the cylinder body, and then seawater is continuously injected into the gantry tube, which can effectively dissipate the heat of the cable body, effectively avoiding the problem of overheating of the cable body due to high-power transmission and affecting its service life. The potential energy of the waves is used to cool the cable in the gantry tube, which has a good energy-saving effect.

[0015] 3. The cable body is provided with an anti-fouling coating to make the surface of the cable body smooth. When marine pollutants such as barnacles adhere to the cable, the marine pollutants are automatically washed away by the waves due to the small adhesion between the marine pollutants and the cable body and the cable floating in the sea water, which greatly reduces the corrosion of the marine pollutants to the cable.

DETAILED DESCRIPTION

[0021] In order to better understand the technical content of the present invention, specific embodiments are provided below, and the present invention is further described in conjunction with the accompanying drawings.

[0022] See also Figures 1 to 4The present invention provides an energy-saving self-cleaning suspended marine cable, comprising a gantry tube 3, a cable body 1, a cylinder 12 and a piston 13. Both ends of the gantry tube 3 are fixedly provided with floating seats, and two support columns 4 are slidably penetrated on the floating seats. The support columns 4 are fixedly installed on the seabed 2. The cable body 1 is movably arranged in the gantry tube 3, so that there is a cooling channel for seawater to flow between the cable body 1 and the inner cavity of the gantry tube 3, and the cable body 1 is supported. The ship can pass through the gantry tube 3 and pass under the cable body 1, avoiding the propeller entanglement with the cable to damage the cable body 1 and the propeller, which is conducive to the ship to select the best route, and sealing members 18 are provided between the cable body 1 and the two ends of the gantry tube 3. The sealing members 18 seal the two ends of the gantry tube 3 to avoid seawater from passing through the cable body 1 and the gantry tube 3. Water flows out between the gantry pipes 3, thereby increasing the contact area between the seawater and the cable body 1, which is beneficial to improving the cooling effect. The cylinder body 12 is fixedly installed on the upper surface of the floating seat. A suction pipe 6 and a drainage pipe 14 are provided on the top of the cylinder body 12. A suction check valve 11 is provided on the suction pipe 6, and the suction pipe 6 extends below the sea level. A drainage check valve 17 is provided on the drainage pipe 14, and the drainage pipe 14 is connected to the left end of the gantry pipe 3. The other end of the gantry pipe 3 is connected to the drainage pipe 21. The suction pipe 6, the drainage pipe 14 and the drainage pipe 21 are all hard pipes. The piston 13 is slidably arranged in the cylinder body 12. A piston rod 10 is fixedly arranged on the lower surface of the piston 13. The piston rod 10 slides out of the bottom of the cylinder body 12 and is provided with a floating block 7. The floating block 7 is located on the sea surface and is driven up and down by the waves.

[0023] When in use, the number of gantry tubes 3 can be set according to the distance between the island and the inland, which is beneficial to shortening the route. Generally, a gantry tube 3 is set at an interval of 0.5 nautical miles to 1 nautical mile, and the support column 4 is slidably penetrated on the floating seat, so that when the tide causes the sea surface water level to change, the floating seat drives the gantry tube 3 to rise and fall with the water level, so as to avoid the ship hitting the top of the gantry tube 3 due to the rising water level during high tide, which can effectively protect the ship, the gantry tube 3 and the cable body 1, and there is no need to set the gantry tube 3 too high, which greatly improves the wind resistance of the gantry tube 3; the cable body 1 is arranged in the gantry tube 3, which can effectively avoid the acidic substances and pancreatic enzyme proteins in the seabird droppings from corroding the cable body 1. At the same time, the ship can pass through the gantry tube 3 and cross the strait, which avoids the ship directly pressing over the cable body 1 and causing the propeller to entangle the cable, thereby causing damage to the cable and the propeller, which is beneficial for the ship to choose the best route. , thereby reducing the cost of navigation; and the potential energy of the waves is used to drive the buoy 17 to float up and down on the sea surface, and the buoy 17 drives the piston 13 to slide up and down in the cylinder 12. When the piston 13 slides downward, the water suction one-way valve 11 is opened, and the drainage one-way valve is closed, so that seawater is sucked into the cylinder 12 through the water suction pipe 6. When the piston 13 slides upward, the water suction one-way valve 11 is closed, and the drainage one-way valve 17 is opened, so that the seawater in the cylinder 12 is transported to the left end of the gantry pipe 3 through the drainage pipe 14, and the seawater is input into the gantry pipe continuously, so that the seawater in the gantry pipe 3 passes over the cable body 1 and flows to the right end of the gantry pipe 3. The seawater is discharged through the drainage pipe 21, which can effectively dissipate the heat of the cable body 1 in the gantry pipe 3, effectively avoiding the problem that the cable body 1 is overheated due to high-power transmission and affecting its service life, and using the potential energy of the waves to cool the cable body 1, it has a good energy-saving effect.

[0024] Specifically, the cable body 1 has a foamed inner protective layer 101, an outer protective layer 102 is provided on the outer surface of the foamed inner protective layer 101, and an anti-fouling coating 103 is provided on the outer surface of the outer protective layer 102. The anti-fouling coating 103 is used to make the surface of the cable body 1 smooth. When marine pollutants such as barnacles adhere to the cable body 1, the adhesion between the marine pollutants and the cable body 1 is effectively reduced, so that the marine pollutants are automatically washed away by the waves, effectively avoiding the corrosion of the cable body 1 by the marine pollutants.

[0025] Specifically, the floating seat includes a support seat 16, a floating block 25 is fixedly provided on the lower surface of the support seat 16, a support column 4 is slidably penetrated on the support seat 16 and the floating block 25, the floating block 25 can be made of low-density materials in the prior art such as foamed polyurethane, the two ends of the gantry tube 3 are respectively fixedly connected to the two support seats 16, and the end of the gantry tube 3 extends on the lower surface of the floating block 25, the ends of the drain pipe 14 and the drain pipe 21 both pass through the support seat 16 and the floating block 25 and are respectively connected to the two ends of the gantry tube 3, so that the cable body 1 is penetrated from underwater into the left end of the gantry tube 3, and penetrated from the right end of the gantry tube 3 into the water, and the piston 13 is used to transport seawater to the right end of the gantry tube 3, and the seawater is then discharged through the right side of the gantry tube 3, so that the cable body 1 is in contact with the seawater as a whole, which greatly improves the cooling effect.

[0026] Specifically, a bracket 15 is fixedly connected to the cylinder body 12, and the bracket 15 is fixedly installed on the upper surface of a support seat 16. The end of the piston rod 10 is connected to a support seat 2 8, and a float block 7 is fixedly installed on the lower surface of the support seat 2 8. The float block 7 can be made of low-density materials in the prior art such as foamed polyurethane.

[0027] Specifically, a connecting hole 9 is provided at the bottom of the cylinder body 12 , and the connecting hole 9 is used to connect the space below the cylinder body 12 with the outside to avoid pressure accumulation in the space below the cylinder body 12 , which may cause the piston 13 to be unable to move in the cylinder body 12 .

[0028] Specifically, the end of the second drainage pipe 21 is installed above the gantry pipe 3 through the pipe rack 20, so that the gantry pipe 3 can be discharged from the end of the second drainage pipe 21 only after it is filled with seawater, so that the cable body 1 is completely immersed in seawater for heat dissipation, which greatly improves the heat dissipation effect.

[0029] Specifically, solar lamps 19 are installed on both sides of the gantry tube 3. The solar lamps 19 have photovoltaic panels, batteries and photosensors. The photovoltaic panels are used to collect solar energy to charge the batteries. The photosensors detect the brightness of light to control the switch of the solar lamps 19. At night, the solar lamps 19 can turn on automatically to guide the ships to pass through the gantry tube 3 smoothly, which is convenient for navigation.
