The hoses are divided into a bow floating hose and a stern floating hose, and are connected with the shuttle tanker in a mode of combining the two hoses or taking one of the two hoses according to the size of the FPSO. When the output work is not carried out, the output hose is rolled up and stored at the roller. However, when the hose is used for offshore oil and gas transportation, the distance between two ships is about 100-200 m, and the hose is extremely difficult to identify, and is difficult to find particularly at night.

However, in the case of a fishing boat which is continuously operated at night, the warning tape cannot function, and the external hose still has a great risk. Once a collision accident occurs, serious consequences such as crude oil leakage and overturning of a fishing boat are easily caused, and heavy losses of personnel, property and environment are brought. Considering that the requirements of the luminous body material on technical conditions such as environmental tolerance, service life, applicable working conditions and the like are limited, the luminous body material cannot be directly used on the output floating hose, and the night identification of the output floating hose is difficult.

The water-stop sheet 17 surrounding the periphery of the hose 1 is connected with the wall of the hose 1 in a sealing way, and seals the two sides of the reverse electric osmosis layer, the electroluminescent film 6, the filter layer 7 and the protective layer 8, so that seawater and other impurities can be prevented from flowing into the reverse electric osmosis layer, and the port of the hose 1 is not blocked. The seawater can only penetrate through the protective layer 8, the filter layer 7 and the porous structure on the electroluminescent film 6 in one direction to enter the reverse electro-osmosis layer, and the ion exchange rate between the seawater and the fresh water in the ion exchange tube is controlled.

As shown in fig. 3 to 5, the application method of the present invention comprises the following steps:

① A plurality of luminous warning bands with the same number of ion exchange tubes are prefabricated on the outer surface of the hose 1 at intervals, the ion exchange tubes with the same polarity are corresponding, the adjacent luminous warning bands are communicated with each other by the waterproof connecting tubes 9 in a hot melting mode, the head ends of the ion exchange tubes on the head luminous warning band and the tail ends of the ion exchange tubes on the tail luminous warning band are connected with the waterproof connecting tubes 9 in a hot melting mode, the ion exchange tubes and the waterproof connecting tubes 9 which are mutually communicated along the axial direction of the hose 1 jointly form an ion exchange channel, when the hose 1 is discontinuous, two sections of hoses can be connected by the connecting flange 10, preset holes with the same number as the number of the anion exchange tubes and the anion exchange tubes are arranged on the connecting flange 10, and the waterproof connecting tubes 9 are penetrated through the preset holes.

② A pair of adjacent anion and cation exchange channels on the front luminous warning band are used as water injection ends, water inlet pipes 12 penetrating the connection flange 10 at the head end of the hose 1 are communicated with the ports of the cation exchange channel and the anion exchange channel, and the two water inlet pipes 12 are communicated with the water delivery pump 15 through a three-way pipe 13.

③ the end of the cation exchange channel at the water injection end is connected with the end of the adjacent cation exchange channel at one side through the channel connecting pipe 11 clockwise or counterclockwise, then the head end of the cation exchange channel is connected with the head end of the next cation exchange channel through the channel connecting pipe 11 continuously along the circumference direction, so that the head end and the end of each cation exchange channel are sequentially connected in turn until the head end is connected with the adjacent cation exchange channel at the other side of the water injection end, thus realizing the unidirectional communication of all cation exchange channels, the end of the anion exchange channel at the water injection end is connected with the end of the adjacent anion exchange channel through the channel connecting pipe 11 continuously along the previous circumference direction, then the head end of the anion exchange channel is connected with the head end of the next anion exchange channel through the channel connecting pipe 11 until the end is connected with the adjacent anion exchange channel at the other side of the water injection end, and all the like ion exchange channels are connected end to end, thus realizing the unidirectional transmission of fresh water to all the ion exchange channels.

④ the ports of a pair of anion and cation exchange channels adjacent to the other side of the water injection end which are not connected with the channel connecting pipe 11 are all communicated with a drainage pipeline 14 which is arranged on the hose 1 at the side and is connected with the flange 10, the two drainage pipelines 14 are communicated with the ion concentration detector 16 through a three-way pipe 13, and the ion concentration detector 16 is connected with a drainage pipe 19.

⑤ placing the hose 1 with the above structure in the sea, delivering fresh water to the anion and cation exchange channels at the water injection end through the water delivery pump 15, and closing the water delivery pump 15 after all the ion exchange channels are filled with fresh water, so that the fresh water is retained in the ion exchange channels.

Seawater sequentially penetrates through the protective layer 8, the filter layer 7 and the electroluminescent film 6 to enter the reverse electro-osmotic layer. Because the solution concentration is different on the two sides of the anion-cation exchange tube and the cation exchange tube 2, cations in seawater can flow to the anode plate 4 through the cation exchange tube under the pushing of concentration difference, anions can flow to the cathode plate 5 through the anion exchange tube 3 under the pushing of concentration difference, and fresh water in the ion exchange tube can permeate to the outside under the pushing of concentration difference. When electrons are transferred from the anode plate 4 to the cathode plate 5, a current is generated and is guided by the anode plate 4 and the cathode plate 5 connected to the electroluminescent film 6, and the electroluminescent film 6 is supplied with power, thereby generating a voltage. The electroluminescent film 6 can be made of a thin film electroluminescent material, and the electroluminescent film 6 is formed by sandwiching a light emitter between two parallel plate electrodes, for example, the plate electrodes are made of transparent conductive glass. Electrons injected from the cathode and holes injected from the anode in the electroluminescent thin film 6 form excitons in the organic layer driven by an external voltage, and transfer energy to molecules of the organic light emitting substance to be excited to transition from a ground state to an excited state, and the excited molecules radiate and transition to emit light when returning from the ground state to the ground state, thereby causing the electroluminescent thin film 6 to emit light as a whole. When light passes through the protective layer 8, a yellow-green PVC light-transmitting film is attached to the inner wall of the protective layer 8, so that light viewed from the outside is yellow-green.

⑥ the worker regularly observes the intensity of the light emitted by the warning belt, when the visibility of the light emitted by the warning belt is low at night, the mouth of the discharge pipe 19 of the ion concentration detector 16 arranged on the platform is opened to discharge the old fresh water in the ion exchange channel, then the water pump 15 injects new fresh water into the ion exchange channel, and the discharge pipe 19 is closed after the fresh water is full, thereby maintaining the ion exchange of the anion and cation exchange tubes and ensuring the continuous light emission of the warning belt, meanwhile, the chlorine ion concentration of the fresh water in the pipeline detected by the ion concentration detector 17 can be observed, and when the chlorine ion concentration is higher than 200ppm, the new fresh water is injected into the pipeline again.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
