[0002] In order to facilitate the direct connection of electrical equipment such as sonar systems with the ocean and meet the relevant requirements of classification societies, large wells and cable protection pipes are usually added to the hull structure from the bottom of the ship to the waterline to protect related electrical components and cables.

[0003] The cost of using steel structure enclosures to protect electrical components and cables is high, and due to the influence of passages, construction space, etc., the enclosures are often large. If the hull structure size remains unchanged, the space of some functional cabins will become smaller. Summary of the Invention

[0021] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0022] like Figure 1 As shown, the present invention provides a device for protecting electrical components from seawater, comprising:

[0023] A seagoing steel pipe 1, which passes through at least one deck, with the lower end of the seagoing steel pipe 1 fixed to the hull structure and the outer wall of the seagoing steel pipe 1 sealed and connected to the deck;

[0024] MCT penetration 4 is installed at the upper inlet of the sea-going steel pipe 1 and is used to seal the outlet of electrical components on the upper waterline of the sea-going steel pipe 1;

[0025] The ventilation pipe 5, the lower end of the ventilation pipe 5 is connected to the sea-going steel pipe 1, and the connection is close to the upper end inlet of the sea-going steel pipe 1.

[0026] Specifically: Further: Also included: a bronze stop valve 6, the lower end of the vent pipe 5 is connected to the sea-going steel pipe 1 through the bronze stop valve 6. The bronze stop valve 6 should be set near the upper end inlet of the device for sea protection of electrical components for easy observation and control.

[0027] The sea-going steel pipe 1 is used to protect electrical components such as cables and probes. The MCT through-hole 4 is used as a sealing material at the outlet of electrical components on the upper waterline of the device for protecting electrical components from sea-going ...

[0028] When water enters the lower end of the device for protecting electrical components from the sea, pressure will be generated when the upper part is sealed, making it impossible to completely immerse the electrical components in seawater. A vent pipe 5 is added to the upper part of the device for protecting electrical components from the sea, near the upper inlet, and a bronze stop valve 6 is provided. The gas in the sea-passing steel pipe 1 can be discharged and closed after discharge to ensure the watertightness of the device for protecting electrical components from the sea.

[0029] Further: it also includes: a penetrating steel casing 2, and the seagoing steel pipe 1 passes through the deck through the penetrating steel casing 2.

[0030] Furthermore, the thickness of the steel casing 2 is at least 1.25 times the thickness of the seagoing steel pipe 1, ensuring the watertightness of the device.

[0031] Furthermore: it also includes: a connecting steel casing 3, the sea-going steel pipe 1 is divided into at least two sections that are connected in sequence, and the two adjacent sections of the sea-going steel pipe 1 are connected by the connecting steel casing 3.

[0032] Furthermore, the thickness of the connecting steel casing 3 is at least 1.25 times the thickness of the sea-going steel pipe 1, thereby ensuring the watertightness of the device.

[0033] Since the electrical detection point on the bottom of the ship to the electrical detection equipment on the waterline usually passes through several decks, the through steel casing 2 is used as a through piece and the connecting steel casing 3 is used as a connecting piece to connect each section of the sea-going steel pipe 1 and ensure the watertightness of the cabin after the sea-going steel pipe 1 passes through the cabin.

[0034] Furthermore, it also includes: reinforcing brackets 7, which are circumferentially spaced and distributed on the outer wall of the lower end outlet of the sea-going steel pipe 1. The side surfaces of the reinforcing brackets 7 are connected to the outer wall of the lower end outlet of the sea-going steel pipe 1, and the bottom surfaces of the reinforcing brackets 7 are fixed to the hull structure. The reinforcing brackets 7 are used to fix the lower end of the sea-going steel pipe 1 to the hull structure.

[0035] Furthermore, the thickness of the reinforcement bracket 7 is the same as that of the bottom plate of the ship. The thickness of the reinforcement bracket 7 is consistent with that of the bottom plate of the ship to ensure the stability of the device.

[0036] Furthermore, the bending angle of the sea-connected steel pipe 1 is not greater than 30 degrees, which reduces the wear on the inner wall of the sea-connected steel pipe 1 when pulling out the gas components or cables.

[0037] Furthermore, the upper end of the vent pipe 5 extends above the weather deck. The upper end of the vent pipe 5 should be set as high as possible above the weather deck to prevent seawater from escaping from the vent pipe 5 when the water pressure of the device used for sea protection of electrical components is too high.

[0038] The appropriate size of the sea-passing steel pipe 1 is selected according to the space requirements of the cables or electrical components, so that the ends of the electrical components will only float in the lower end of the device for protecting the electrical components from the sea, without the need to use additional special structures to fix the electrical components.

[0039] It can be seen from the above scheme that the present invention provides a device for protecting electrical components in the sea, which meets the requirements of classification society specifications and replaces the original combination of a well and a cable protection pipe to protect electrical components and cables. The cost is reduced and the space impact is small. The device for protecting electrical components in the sea can be applied anywhere on the ship.

[0040] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
