Technical Field

The invention relates to a fire protection device, in particular to a fire protection device for a ship.

Background

The current ships all have an electrical room, and each consumer on the ship is connected to the electrical room through the cable electricity, and the cable all has flammable sheath and insulating layer generally, and in this case, in case of a fire, the intensity of a fire can spread to whole boats and ships along the cable, can bring huge loss risk. Therefore, the existing ships are isolated by using a fireproof wall and the like at certain intervals, cables are laid in a line passing hole mode penetrating through the fireproof wall, and then a gap of the line passing hole is filled with a fireproof material; secondly, when the intensity of a fire burns the firewall along the cable, the sheath and the insulating layer in the wire passing hole are easy to soften and shrink, so that a gap appears in the wire passing hole, and the intensity of the fire is spread.

Disclosure of Invention

The invention aims to provide a fireproof device for a ship, which can effectively prevent fire from spreading along a cable when the ship catches fire.

The technical scheme of the invention is as follows:

a fire protection device for a ship comprises a line passing hole formed in a fireproof wall of the ship, a cable penetrating through the line passing hole, and a fire blocking device used for preventing fire from spreading along the cable, wherein the fire blocking device comprises a heat pipe, a blocking box body fixed on the fireproof wall of the ship, a line passing hole formed in the side wall of the blocking box body, a water storage tank positioned on the upper portion of the blocking box body or positioned above the blocking box body, and a drain pipe arranged on the bottom surface of the water storage tank, the cable penetrates through the line passing hole, the cable positioned in the blocking box body is provided with a lower extension part formed by bending downwards, the heat pipe is fixed on the cable, the heat pipe and the cable are distributed in parallel, the first end of the heat pipe and the fireproof wall are positioned on two opposite sides of the blocking box body, the second end of the heat pipe penetrates through the line passing hole and is positioned in the blocking box body, and the second end, the trigger section extends upwards into the drainage pipe from the lower port of the drainage pipe, a drainage gap is formed between the trigger section and the pipe wall of the drainage pipe, and wax is filled in the drainage gap to seal the drainage gap; when the wax is melted, the water in the water storage tank flows downwards into the blocking box body through the drainage gap so as to immerse a part of the lower extension part. Compared with the fire-proof structure in the prior art that the cable is laid in a way of penetrating through the line passing hole of the fire-proof wall and the gap of the line passing hole is filled with the fire-proof material, the fire-proof material filled in the line passing hole can loosen and fall off due to the long-term shaking of the ship, so that the fire spread is caused; and when the fire is burnt to the fireproof wall along the cable, the sheath and the insulating layer in the wire through hole are easy to soften and shrink, so that a gap is formed in the wire through hole, and the fire is spread; according to the scheme, the fire blocking device is used for preventing the fire from spreading and diffusing along the cable, specifically, in the process of spreading the fire along the cable, when the open fire on the cable is close to the first end of the heat pipe, the first end of the heat pipe is heated, at the moment, the heat pipe rapidly conducts heat from the first end of the heat pipe to the second end, so that the wax in the drainage gap is melted, water in the water storage tank flows downwards into the blocking box body through the drainage gap, and a part of the lower extension part is immersed before the fire spreads to the lower extension part along the cable by utilizing the time difference of spreading the fire along the cable; therefore, when the fire spreads to the lower extension part along the cable, the fire is blocked by the water at the bottom of the blocking box body, so that the fire is effectively prevented from continuously spreading and spreading along the cable, and the heat of the cable at the burning part can be effectively blocked from being transmitted backwards through the conductor of the cable; the cable can effectively prevent the fire from continuously spreading and diffusing along the cable, is not influenced by ship shaking, and does not have the problem that the fire spreading is caused by the possibility of loosening and falling of the refractory material filled in the wire passing hole; and when the fire is burnt to the fireproof wall along the cable, the sheath and the insulating layer in the wire passing hole are easy to soften and shrink, so that a gap is formed in the wire passing hole, and the fire is spread.

Preferably, the lower extension part is U-shaped and comprises a left vertical cable section and a right vertical cable section and a lower cable section which is connected with the lower ends of the left vertical cable section and the right vertical cable section, and the lower cable section is close to the bottom of the blocking box body.

Preferably, a support is arranged in the blocking box body and above the lower extension part, and the water storage box is supported on the support. Therefore, the water storage tank is convenient to install.

Preferably, an annular baffle is arranged on the heat pipe in the blocking box body. So, wax when melting, the in-process that the water in the storage water tank will flow down through the drainage clearance can be avoided water to flow to the cable that blocks the box outside along the heat pipe on.

Preferably, the upper end opening of the case is blocked. Therefore, the water storage tank is convenient to install.

Preferably, the wire passing port is communicated with the upper end face of the blocking box body. In this manner, the lower extension of the cable is conveniently disposed within the blocker box.

Preferably, the fire break-off means are two, the two fire break-off means being distributed on both sides of the fire wall.

Preferably, the heat pipe is held tightly on the cable by a hoop.

Preferably, the water storage tank includes a tank body having an upper end opening, and an upper cover covering the upper end opening of the tank body.

The invention has the beneficial effects that: when a ship catches fire, the fire can be effectively prevented from spreading along the cable; the influence of ship shaking is avoided, and the problem that fire spread is caused by the possibility that the refractory material filled in the wire passing hole is loosened and falls off is solved; and when the fire is burnt to the fireproof wall along the cable, the sheath and the insulating layer in the wire passing hole are easy to soften and shrink, so that a gap is formed in the wire passing hole, and the fire is spread.
