[0027] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, "multiple" means two or more, unless otherwise clearly and specifically defined. In addition, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the internal communication of two components.

[0030] Combination Figures 1 to 5 As shown, a marine high-pressure oil pipe provided by the utility model includes a reinforcement layer 1, a pin 2 and an external resistance meter.

[0031] Combination Figures 1 to 5 As shown, the reinforcement layer 1 includes a metal layer 11 and an insulating layer 12. The metal layer 11 has two layers. The insulating layer 12 is sandwiched between the two metal layers 11 to separate the two metal layers 11. The number of pins 2 is 2, and two of the pins 2 are electrically connected to one layer of the metal layer 11 respectively. The external resistance meter is electrically connected to the two pins 2.

[0032] In this embodiment, an insulating layer 12 is sandwiched between two metal layers 11. When seawater leaks inward and passes through the insulating layer 12, the two metal layers 11 are connected due to the conductivity of the seawater. The positive and negative poles of the external resistance meter are electrically connected to the two metal layers 11 respectively, and the two metal layers 11 are used as the positive and negative poles, and the position where the seawater penetrates is used as the positive and negative pole connection point to form a closed loop. When the loop is connected, the reading of the external resistance meter will change from large to small, thereby judging the occurrence of leakage. The longer the circuit flow length, the greater the circuit resistance value, combined with the size of the resistance meter reading and the conductivity of the metal layer 11, the positive proportional relationship between the circuit conduction length and the resistance value can be used to estimate the location of the leakage point.

[0033] In some embodiments, in combination Figure 1 As shown, the metal layer 11 includes a metal spring 111. The metal spring 111 has better elastic deformation properties than traditional metal pipes. The metal layer 11 composed of the metal spring 111 can retain the elastic properties of the oil hose, thereby facilitating the installation of the oil hose.

[0034] In some embodiments, in combination Figure 1 As shown, the metal springs 111 in the two metal layers 11 are wound in opposite directions. When the oil delivery hose is bent, the metal springs 111 wound in opposite directions can avoid stress concentration and increase the bending life of the oil delivery hose.

[0035] In some embodiments, in combination Figure 1 As shown, the metal layer 11 also includes a filler, and the filler is filled in the gap of the metal spring 111. The filler is woven from polyester fibers, and the polyester fibers are insulating in a dry state. When seawater leaks and penetrates into the polyester fibers, this portion becomes conductive and causes the reading of the external resistance meter to change. However, at this time, the structure of the metal layer 11 has not been destroyed, and the occurrence of diffusion can be suppressed to a certain extent.

[0036] In some embodiments, in combination Figure 1As shown, the insulating layer 12 is woven from polyester fibers, and in this embodiment also includes an inner liner layer 3 and an outer rubber layer 4, which are mainly used to block crude oil and seawater. When the outer rubber layer 4 is blocked, seawater will directly penetrate into the insulating layer 12 to connect the two metal layers 11, reminding the operator of the occurrence of leakage; avoiding the occurrence of leakage of the outer rubber layer 4 due to the blocking of the insulating layer 12 and not being discovered.

[0037] In some embodiments, in combination Figure 1 As shown, the insulating layer 12 also includes a supporting ring 121, which is embedded in the insulating layer 12 and evenly distributed along the insulating layer 12. The supporting ring 121 mainly supports the shape of the oil hose, improves the strength of the oil hose, and enables it to work normally in a high-pressure environment.

[0038] In some embodiments, in combination Figure 1 As shown, the reinforcing layer 1 also includes a wear-resistant layer 13. The wear-resistant layer 13 has two layers. The two wear-resistant layers 13 are respectively attached to the side of the metal layer 11 away from the insulating layer 12. Since the metal layer 11 will rub against the adjacent material layer during the elastic deformation process, the wear-resistant layer 13 is designed to withstand friction to increase the service life of the oil hose.

[0039] In some embodiments, in combination Figure 1 As shown, the marine high-pressure oil hose also includes an inner liner layer 3, which is the innermost layer of the marine high-pressure oil hose. The outer side of the inner liner layer 3 is in contact with the reinforcement layer 1, and the inner liner layer 3 is in contact with crude oil. The inner liner layer 3 is usually made of a material with good resistance to corrosion by crude oil. Since the inner liner layer 3 does not need to contact seawater, there is no need to consider the resistance to seawater corrosion, which reduces the requirements for the constituent materials.

[0040] In some embodiments, in combination Figure 1 As shown, the marine high-pressure oil hose also includes an outer rubber layer 4, which is the outermost layer of the marine high-pressure oil hose. The inner side of the outer rubber layer 4 is close to the reinforcing layer 1, and the outer side of the outer rubber layer 4 contacts the seawater. The outer rubber layer 4 is usually made of a material with good resistance to corrosion from seawater. The outer rubber layer 4 does not need to contact crude oil, and there is no need to consider the resistance to corrosion from crude oil, which reduces the requirements for the constituent materials.

[0041] In some embodiments, in combination Figure 1As shown, the marine high-pressure oil hose also includes a connector 5, and the connector 5 includes a mounting groove. The lead-in ends of the two pins 2 are embedded in the bottom surface of the mounting groove, and the reinforcing layer 1 is assembled in the mounting groove. The lead-out ends of the two pins 2 pass through the connector 5 and are arranged on the outer surface of the connector 5. The electrical connection between the pin 2 and the metal layer 11 can be completed during the assembly of the connector 5, and the assembly process is more convenient. At the same time, the lead-in end of the pin 2 arranged on the outer surface of the connector 5 can facilitate the electrical connection of the external resistance meter to the pin 2.

[0042] Working process: When the outermost outer rubber layer 4 is damaged and leakage occurs, the seawater that subsequently penetrates will penetrate into the filler of the metal layer 11 and the insulating layer 12, causing the filler of the metal layer 11 and the insulating layer 12 to lose their insulating ability, and the metal springs 111 in the two metal layers 11 are electrically connected; at this time, the reading of the external resistance meter will change from large to small, and the location of the leakage can be determined in combination with the reading of the resistance meter; at the same time, as the leakage occurs, the amount of seawater that penetrates increases, the conductive area will become larger, causing the reading of the external resistance meter to decrease, and the speed at which the reading of the resistance meter decreases can be used to determine the speed of the leakage.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
