Description

Technical Field

[0001] The present application relates to the field of cables, and in particular to a pressure alarm cable for ships. Background Art

[0002] Cables are usually composed of several or several groups of wires, with at least two wires in each group twisted together. Each group of wires is insulated from each other and are often twisted around a center wire. The entire outside is covered with a highly insulating covering.

DETAILED DESCRIPTION

[0021] The following is combined with Figure 1-9 This application is described in further detail.

[0022] The present application embodiment discloses a pressure alarm cable for ships. Figure 1 , Figure 2 and Figure 3 A pressure alarm cable for ships, comprising a cable core 1, the cable core 1 is wrapped with a rubber layer 2 by injection molding, a filling skeleton 3 is provided on the side of the rubber layer 2, a protective layer 4 is provided on the outside of the filling skeleton 3, an inner insulating layer 5 is provided on the outside of the protective layer 4, an outer insulating layer 6 is fixed to the outer wall of the inner insulating layer 5 by injection molding, a sheath layer 10 is fixed to the outer wall of the outer insulating layer 6 by injection molding, an information transmission cable 7 and a pressure detection mechanism 8 are provided on the inner side of the outer insulating layer 6, the pressure detection mechanism 8 is connected to the information transmission cable 7, an identification sleeve 9 is provided on the outer surface of the sheath layer 10, and the identification sleeve 9 is located on the outside of the pressure detection mechanism 8.

[0023] The protective layer 4 can effectively improve the structural hardness of the inner insulating layer 5, and can prevent the expansion of the damaged wound when the outer wall of the cable is damaged, thereby improving the protection ability of the cable; the main function of the insulating layer is to isolate the current and prevent current leakage, thereby ensuring that the current only flows inside the wire, avoiding the current from directly flowing into the ground or contacting the human body, thereby preventing electric shock accidents; the filling skeleton can protect the cable core 1 and reduce the extrusion of the cable core 1 by external force; the pressure detection mechanism 8 is used to monitor the pressure on the cable, and the information transmission cable 7 is used to transmit the pressure signal of the cable; the identification sleeve 9 is convenient for the staff to intuitively observe the position of the pressure detection mechanism 8 to avoid damage to the pressure detection mechanism 8 when cutting the cable.

[0024] Refer to 3 and Figure 4The pressure detection mechanism 8 includes an outer shell 81, a contact plate 82, a connecting rod 83, a piston plate 84, a pressure chamber 85, a torsion spring 86, a pressure-sensitive member 87 and a rotating rod 88. The outer shell 81 is placed on the inner side of the outer insulating layer 6. A pressure chamber 85 is provided inside the outer shell 81. The contact plate 82 is attached to the inner side of the outer insulating layer 6. The connecting rod 83 is fixedly connected to the other side of the contact plate 82. One end of the connecting rod 83 is fixedly connected to the piston plate 84. The piston plate 84 is placed in the pressure chamber 85. The piston plate 84 is slidably connected to the pressure chamber 85. The rotating rod 88 is symmetrically arranged on the side wall of the outer shell 81. One end of the rotating rod 88 is connected to the torsion spring 86, and one end of the torsion spring 86 is connected to the pressure chamber 85.

[0025] When the cable is subjected to slight pressure, the contact plate 82 drives the connecting rod 83 and the piston plate 84 to move downward, and the piston plate 84 contacts the rotating rod 88. The rotating rod 88 hinders the movement of the piston plate 84 due to the presence of the torsion spring 86, which relieves the pressure on the cable to a certain extent and does not trigger the alarm mechanism.

[0026] When the pressure on the cable exceeds the threshold, the piston plate 84 pushes the rotating rod 88 into the side wall of the outer shell 81, and the piston plate 84 moves downward. The space in the pressure chamber 85 is sharply reduced, so that the pressure in the pressure chamber 85 increases sharply. The pressure sensing element 87 detects the change in pressure and transmits the alarm signal to the terminal device through the information transmission cable 7.

[0027] Reference Figure 4 , Figure 5 and Figure 6 An external bin 811 is also provided on the side wall of the outer shell 81, and a first rotating rod 812 is provided in the external bin 811.

[0029] When the rotating rod 88 is retracted into the side wall of the outer shell 81, the trigger protrusion 881 is retracted into the side groove 853, and the soft metal sheet 852 is deformed along with the trigger protrusion 881. The soft metal sheet 852 contacts the contact protrusion 814, and the first rotating rod 812 rotates around the rotating axis 813. The first cross bar 815 moves in the air intake duct 851 along with the first rotating rod 812. The movement of the first cross bar 815 increases the pressure in the pressure chamber 85.

The light-emitting belt 92, the battery 93 and the signal receiver 94 are electrically connected.

[0032] The metal contact block 843 is retracted inside the piston plate 84. When the piston plate 84 moves to the electrode plate 854, the telescopic spring 842 pushes the metal contact block 843 out, and the metal contact block 843 contacts the electrode plate 854. When the metal contact block 843 contacts the electrode plate 854, a signal is transmitted to the wireless transmission module 855. The transmitted signal is captured by the signal receiver 94, thereby lighting up the light strip 92, making it easier for the staff to intuitively observe the compressed position.

[0033] Reference Figure 3 The filling skeleton 3 is made of hard plastic and is integrally formed. The filling skeleton can protect the cable core 1 and reduce the extrusion of the cable core 1 by external force.

[0037] The implementation principle of a pressure alarm cable for ships in the embodiment of the present application is: When the cable is subjected to slight pressure, the contact plate 82 drives the connecting rod 83 and the piston plate 84 to move downward, and the piston plate 84 contacts the rotating rod 88. The rotating rod 88 hinders the movement of the piston plate 84 due to the presence of the torsion spring 86, which relieves the pressure on the cable to a certain extent and does not trigger the alarm mechanism.

[0038] When the pressure on the cable exceeds the threshold, the piston plate 84 pushes the rotating rod 88 to retract into the side wall of the outer shell 81, and the piston plate 84 moves downward, and the space of the pressure chamber 85 is sharply reduced, so that the pressure in the pressure chamber 85 increases sharply. At the same time, the trigger protrusion 881 is retracted into the side groove 853, and the soft metal sheet 852 is deformed along with the trigger protrusion 881. The soft metal sheet 852 contacts the contact protrusion 814, and the first rotating rod 812 rotates around the rotating shaft 813. The first cross bar 815 moves in the air intake duct 851 along with the first rotating rod 812. The movement of the first cross bar 815 also makes The pressure in the pressure chamber 85 increases, and the pressure-sensitive element 87 detects the change in pressure. The pressure-sensitive element 87 transmits an alarm signal to the terminal device through the information transmission cable 7. At the same time, when the piston plate 84 moves to the electrode sheet 854, the telescopic spring 842 pushes the metal contact block 843 out, and the metal contact block 843 contacts the electrode sheet 854. When the metal contact block 843 contacts the electrode sheet 854, a signal is transmitted to the wireless transmission module 855.
