[0036] Figure 2is a schematic structural diagram of a second weather-resistant cable of the present invention, Figure 3 This is a structural schematic diagram of the first weather-resistant cable of the present invention. The end of the first weather-resistant cable 1 is fixedly connected with a first connector 5, and the first weather-resistant cable 1 is fixedly connected with a connecting sleeve 51 at the outer edge of the first connector 5, and both sides of the connecting sleeve 51 are fixedly connected with a first docking seat 3, and an insertion block 31 is fixed at the end of the first docking seat 3, and a slot 32 is provided on the insertion block 31, and a connecting sleeve 51 is fixedly connected at the outer edge of the first connector 5, and the connecting sleeve 51 is used to enhance the stability of the cable connection part and provide an easy-to-operate interface.

[0037] The end of the second weather-resistant cable 2 is fixedly connected to the second connector 6, and the outer surface of the second connector 6 is provided with an annular groove 61. The second connector 6 is fixedly connected to the second docking seat 4 on both sides, and the second docking seat 4 is provided with a slot 41. The second connector 6 is plugged into and electrically connected to the first connector 5, and is a part of the connector, which is used to ensure the precise alignment and firm fixation of the cable connection. The connecting sleeve 51 is sleeved on the outer surface of the second connector 6, and the end of the plug block 31 matches the slot 41.

[0038] When two weather-resistant cables need to be connected, the first connector 5 of the first weather-resistant cable 1 and the second connector 6 of the second weather-resistant cable 2 are plugged into each other, and the connecting sleeve 51 is sleeved on the outer surface of the second connector 6 to provide additional support and protection. The plug block 31 of the first docking socket 3 matches the slot 41 of the second docking socket 4 to ensure precise alignment of the cable connection.

[0039] Figure 4 is a schematic diagram of the structure of the limit assembly of the present invention, Figure 5 For the present invention Figure 4 In the structural schematic diagram enlarged at point A in the middle, a limit assembly is provided on the second docking seat 4 for easy expansion and adjustment, the limit assembly includes a pulling rod 43, a receiving groove is provided on the second docking seat 4, a mounting block 42 is provided at the opening of the receiving groove, the mounting block 42 is fixed to the second docking seat 4 by screws, the pulling rod 43 is slidably inserted on the mounting block 42, the end of the pulling rod 43 is fixedly connected with a clamping block 44, the pulling rod 43 is sleeved with an abutment spring 45, the clamping block 44 is a "T"-shaped block structure, and the end is inserted into the clamping slot 32.

[0040] An expansion space is provided on the end of the card block 44 on the second docking seat 4, and grooves 46 are provided on both sides of the end of the card block 44. A fixing pin 47 is fixedly connected in the groove 46 on the card block 44, and an abutment block 49 is rotatably sleeved on the fixing pin 47. A torsion spring 48 is sleeved on the fixing pin 47, and the ends of the abutment blocks 49 on both sides abut the edge of the expansion space. One end of the torsion spring 48 is fixedly connected to the fixing pin 47, and the other end is fixedly connected to the abutment block 49. The elastic force of the abutment spring 45 is much greater than the torsional force of the torsion spring 48. The use of the torsion spring 48 provides a constant pressure for the abutment block 49, so that it always abuts against the edge of the expansion space, thereby enhancing the overall relative stability of the connector.

[0041] When the first weather-resistant cable 1 and the second weather-resistant cable 2 need to be connected, the first docking seat 3 and the second docking seat 4 are aligned with each other and inserted, and the pulling rod 43 can adjust the position according to actual conditions to ensure accurate docking between the plug block 31 and the slot 41. The card block 44 is inserted into the card slot 32 through its "T"-shaped structure to provide stable mechanical locking; the pressure of the abutment spring 45 ensures that the card block 44 is firmly locked in the card slot 32, and the abutment block 49 on the fixing pin 47 provides additional support and stability under the action of the torsion spring 48. This design allows the connector to have a certain degree of flexibility when docking while ensuring the firmness and reliability of the connection.

[0042] Figure 6 It is a structural schematic diagram of the end of the card block of the present invention, Figure 7 For the present invention Figure 6 The enlarged structural diagram at B in the middle, Figure 8 is a cross-sectional view of the second docking seat of the present invention, Fig. 9 For the present invention Figure 8 The enlarged structural diagram at C in the middle, Fig.10 This is a schematic diagram of the structure of the reinforcement component of the present invention. A reinforcement component for easy sealing is arranged between the second docking seat 4 and the second connecting head 6. The reinforcement component includes a push rod 66. A storage groove is opened on the inner side of the slot 41 on the second docking seat 4. A round block 65 is arranged at the opening of the storage groove. The round block 65 is fixed to the second docking seat 4 by screws. The push rod 66 has a "T"-shaped structure and is slidably inserted on the round block 65. A supporting spring 67 is sleeved on the push rod 66. A cylindrical airbag 68 is bonded between the push rod 66 and the storage groove. One end of the cylindrical airbag 68 is connected to a connecting tube 64. An annular airbag 63 is bonded to the inner side of the annular groove 61 on the second connecting head 6. A sealing ring 62 is bonded to the outer side of the annular airbag 63. The annular airbag 63 is connected to the connecting tube 64.

[0043] The cylindrical airbag 68 and the annular airbag 63 are designed to provide additional sealing when the cable is connected. When inflated, these airbags can fill tiny gaps to prevent moisture, dust or other harmful substances from entering the interior of the connector. The use of the sealing ring 62 further enhances the sealing performance of the connector and ensures the stability and reliability of the cable connection in harsh environments.

[0044] When the first weatherproof cable 1 and the second weatherproof cable 2 need to be connected, in addition to mechanical docking, it also involves the coordinated work of the reinforcement components to ensure the sealing. As the cable connector is plugged in, the push rod 66 will be abutted by the end face of the plug block 31, so that the push rod 66 squeezes the cylindrical airbag 68, which compresses the cylindrical airbag 68, and its gas is transmitted to the annular airbag 63 through the connecting pipe 64. The annular airbag 63 expands and squeezes the sealing ring 62. In this way, the cylindrical airbag 68 and the annular airbag 63 work together to form a double sealing system, which effectively prevents the external environment from corroding the inside of the connector. This design ensures that even under extreme conditions that ocean-going ships may encounter, the cable connection can maintain good sealing and stable electrical connection.

[0045] One side of the insulation layer 11 is connected to a ventilation pipe 7, and the end of the ventilation pipe 7 is connected to the waste heat concentration area of ​​the ocean-going ship's steam turbine unit. The ventilation pipe 7 connects the insulation layer 11 with the waste heat concentration area of ​​the ocean-going ship's steam turbine unit, so that the waste heat can be used to heat the cable, improve energy efficiency and prevent the cable from performing poorly in a low temperature environment.

[0046] Fig.11 is a schematic diagram of the structure of the opening and closing assembly of the present invention, Fig.12 For the present invention Fig.11 The enlarged structural diagram at D in the middle, Fig.13 It is a schematic diagram of the structure inside the fixing seat of the present invention, Fig.14 For the present invention Fig.13 In the enlarged structural schematic diagram at point E in the middle, a fixed seat 8 is fixedly connected to one side of the ventilation pipe 7, an opening and closing assembly is provided between the fixed seat 8 and the second docking seat 4, and between the fixed seat 8 and the first docking seat 3, the opening and closing assembly includes an extrusion rod 83, and a circular groove is provided on the second docking seat 4 and the first docking seat 3, a circular plate 82 is provided at the opening of the circular groove, and the circular plate 82 is fixed to the second docking seat 4 or the first docking seat 3 by screws.

[0047] The extrusion rod 83 is in a "T"-shaped structure and is slidably inserted on the circular plate 82. A pressure air bag 84 is bonded between the extrusion rod 83 and the circular groove. One end of the pressure air bag 84 is connected to a connecting pipe 85. The ends of the extrusion rods 83 on both sides are in contact with each other.

[0048] A cavity is opened on the fixing seat 8, and a cover plate 81 is arranged on the top of the cavity. The cover plate 81 is fixed to the fixing seat 8 by screws. A square air bag 86 is bonded in the cavity, and a movable sealing block 87 is slidably inserted in the cavity. The movable sealing block 87 has an "L"-shaped structure and is bonded to the square air bag 86. A reset spring 88 is fixedly connected between the movable sealing block 87 and the cavity.

[0049] In the original state, the end of the movable sealing block 87 is slidably inserted into the opening section of the ventilation pipe 7. When working, the end of the movable sealing block 87 is away from the opening section of the ventilation pipe 7 to form an opening. One end of the square air bag 86 is connected to the connecting pipe 85. The square air bag 86 and the movable sealing block 87 are designed to close the opening of the ventilation pipe 7 in the ventilation state to prevent hot air from escaping when not needed.

[0050] Hot air is transmitted to the insulation layer 11 through the ventilation pipe 7 to heat the cable and maintain its performance. The opening and closing assembly plays a key role in this process. When ventilation is needed, the extrusion rod 83 will be squeezed by the end face of the first docking seat 3, thereby compressing the pressurized airbag 84. This compression causes the gas to flow to the square airbag 86 through the connecting pipe 85 to expand it. As the square airbag 86 expands, the movable sealing block 87 is pushed, thereby opening the opening of the ventilation pipe 7 and allowing hot air to pass through; when ventilation is no longer needed, the first docking seat 3 and the second docking seat 4 are separated, the external force on the extrusion rod 83 is removed, and the return spring 88 pulls the movable sealing block 87 back to its original position, closing the opening of the ventilation pipe 7.

[0051] During actual installation, the first connector 5 of the first weather-resistant cable 1 and the second connector 6 of the second weather-resistant cable 2 are plugged into each other, and the connecting sleeve 51 is sleeved on the outer surface of the second connector 6 to provide additional support and protection. The plug block 31 of the first docking seat 3 matches the slot 41 of the second docking seat 4 to ensure the precise alignment of the cable connection. When the first weather-resistant cable 1 and the second weather-resistant cable 2 need to be connected, the first docking seat 3 and the second docking seat 4 are aligned with each other and inserted. The pulling rod 43 can adjust its position according to actual conditions to ensure accurate docking between the plug block 31 and the slot 41. The card block 44 is inserted into the card slot 32 through its "T"-shaped structure to provide stable mechanical locking; the pressure of the abutment spring 45 Ensure that the card block 44 is firmly locked in the card slot 32, and the abutment block 49 on the fixing pin 47 provides additional support and stability under the action of the torsion spring 48. This design allows the connector to have a certain degree of flexibility when docking, while ensuring the firmness and reliability of the connection; as the cable connector is plugged in, the push rod 66 will be abutted by the end face of the plug block 31, so that the push rod 66 squeezes the cylindrical airbag 68, causing the cylindrical airbag 68 to be compressed, and its gas is transmitted to the annular airbag 63 through the connecting tube 64, and the annular airbag 63 expands and squeezes the sealing ring 62, so that the cylindrical airbag 68 and the annular airbag 63 work together to form a double sealing system, which effectively prevents the external environment from corroding the inside of the connector. This design ensures that the cable connection can maintain good sealing and stable electrical connection even under extreme conditions that may be encountered by ocean-going ships. At the same time, the opening and closing assembly plays a key role in this process. When ventilation is required, the extrusion rod 83 will be squeezed by the end face of the first docking seat 3, thereby compressing the pressurized airbag 84. This compression causes the gas to flow to the square airbag 86 through the connecting pipe 85 to expand it. As the square airbag 86 expands, the movable sealing block 87 is pushed, thereby opening the opening of the ventilation pipe 7 and allowing hot air to pass through. The hot air is transmitted to the insulation layer 11 through the ventilation pipe 7 to heat the cable and maintain its performance.
