Description

Technical Field

[0001] This utility model relates to the field of marine fire-fighting equipment technology, specifically to a dry powder fire extinguisher rack for ships. Background Technology

[0002] As an important component of ship fire protection systems, marine dry powder fire extinguishing equipment operates in a complex and harsh environment on board, and needs to adapt to the challenges of unstable working conditions such as marine climate and ship movement.

[0003] Dry powder fire extinguishing equipment mainly consists of a cylinder group composed of multiple high-pressure nitrogen cylinders. Each cylinder has a volume of 70L, a nitrogen filling pressure of 13.5 MPa, and an operating weight of approximately 80kg. Under normal operating conditions, if a high-pressure nitrogen cylinder is not securely fixed and tilts, causing a high-pressure nitrogen leak, the reaction force of the released nitrogen can threaten personnel safety and cause significant property damage. Therefore, ensuring the nitrogen cylinders are securely fixed is crucial.

[0004] In the past, the high-pressure nitrogen cylinders in the high-pressure nitrogen cylinder group used in dry powder equipment were fixed by setting cylinder fixing steel straps on a welded steel cylinder frame, and the fixing steel straps were connected to the steel cylinder frame by bolts.

[0005] When a ship experiences significant rolling or swaying due to weather or other factors during operation, the stability and reliability of this structure are greatly compromised. Furthermore, the environment on board ships is often high in humidity and salinity, which can cause corrosion and affect the stability and lifespan of the equipment. Utility Model Content

[0006] To address the aforementioned issues, this utility model provides a dry powder fire extinguisher rack for ships, which improves stability and sealing during installation on ships, thereby extending the service life of the equipment in high humidity and high salt environments.

[0007] To achieve the above objectives, this utility model embodiment adopts the following technical solution: a dry powder fire extinguisher placement rack for ships, including a positioning bracket, a high-pressure gas cylinder is provided on the positioning bracket, a base for placing the high-pressure gas cylinder is provided at the lower part of the positioning bracket, a positioning module for fixing the high-pressure gas cylinder is provided in the middle part of the positioning bracket, a protective shell is provided on the outside of the positioning bracket, a gas supply pipe connected to the high-pressure gas cylinder is provided on the protective shell, and an airtight device is provided inside the protective shell.

[0008] As a further improvement to the above technical solution:

[0009] The positioning module includes a support rod and a clamping rod. The two ends of the clamping rod are detachably connected to the positioning bracket. Limiting blocks located on both sides of the high-pressure gas cylinder are provided on the side wall of the support rod.

[0010] One side of the limiting block is provided with a slope that fits against the side wall of the high-pressure gas cylinder.

[0011] The upper part of the base is provided with a storage slot for placing high-pressure gas cylinders. The height of the storage slot is 1 / 4 of the height of the high-pressure gas cylinders and a buffer pad is provided at the bottom.

[0012] The airtight device includes a purge pipe with an air outlet, and a pressure relief valve is provided on the upper part of the protective housing.

[0013] The purging pipes are distributed along the height of the protective shell, and a tee pipe connected to the gas transmission pipe is provided at the upper part of the purging pipes.

[0014] The number of air outlets is multiple and they are evenly distributed along the height direction of the purging pipe.

[0015] The protective housing has an observation window on at least one side wall.

[0016] The beneficial effects of this utility model embodiment are as follows: The dry powder fire extinguisher placement rack for ships includes a positioning bracket, on which a high-pressure gas cylinder is placed. The lower part of the positioning bracket is provided with a base for placing the high-pressure gas cylinder, and the middle part of the positioning bracket is provided with a positioning module for fixing the high-pressure gas cylinder. The outside of the positioning bracket is provided with a protective shell, and the protective shell is provided with a gas supply pipe connected to the high-pressure gas cylinder. An airtight device is provided inside the protective shell. The positioning module can enhance the stability of the high-pressure gas cylinder placement and prevent the high-pressure gas cylinder from falling over due to the turbulence of the ship. The airtight device can enhance the airtightness of the entire placement rack and prevent corrosion and leakage of the pipeline structure of the high-pressure gas cylinder during long-term operation under high humidity and high salt conditions.

[0023] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0024] like Figure 1-2 As shown, the dry powder fire extinguisher placement rack for ships in this embodiment includes a positioning bracket 1, on which a high-pressure gas cylinder 2 is placed. The lower part of the positioning bracket 1 is provided with a base 3 for placing the high-pressure gas cylinder 2. The middle part of the positioning bracket 1 is provided with a positioning module for fixing the high-pressure gas cylinder 2. The outside of the positioning bracket 1 is provided with a protective shell 4. At least one side wall of the protective shell 4 is provided with an observation window 16. The protective shell 4 is provided with a gas supply pipe 5 connected to the high-pressure gas cylinder 2. An airtight device is provided inside the protective shell 4. The positioning module can enhance the stability of the placement of the high-pressure gas cylinder 2 and prevent the high-pressure gas cylinder from falling over due to the turbulence of the ship. The airtight device can enhance the airtightness of the entire placement rack and prevent the pipeline structure of the high-pressure gas cylinder from corroding and leaking during long-term operation under high humidity and high salt conditions.

[0025] like Figure 3 As shown, the positioning module includes a support rod 6 and a clamping rod 7. The support rod 6 is located on the rear side of the high-pressure gas cylinder 2 and provides support. The clamping rod 7 is located on the front side of the high-pressure gas cylinder 2, and its two ends are detachably connected to the positioning bracket 1 by bolts. The side wall of the support rod 6 is provided with limiting blocks 8 located on both sides of the high-pressure gas cylinder 2. The opposite side walls of the two limiting blocks 8 are provided with ramps 9 that fit against the side walls of the high-pressure gas cylinder 2. By fitting the ramps 9 against the side walls of the high-pressure gas cylinder 2, it is ensured that the equipment will not tilt to the left or right during use, thus enhancing the stability of the placement.

[0026] like Figure 4 As shown, the upper part of the base 3 is provided with a storage slot 10 for placing the high-pressure gas cylinder 2. The height of the storage slot 10 is 1 / 4 of the height of the high-pressure gas cylinder 2 and a buffer pad 11 is provided at the bottom. The storage slot 10 can protect the bottom of the high-pressure gas cylinder 2 to prevent it from falling over or leaking after being hit by a collision.

[0027] like Figure 5As shown, the airtight device includes a purge pipe 12 with multiple air outlets 13 evenly distributed along the height of the purge pipe 12. A pressure relief valve 14 is provided on the upper part of the protective housing 4. The pressure relief valve 14 is a one-way valve. The purge pipe 12 is distributed along the height of the protective housing 4. A three-way pipe 15 connected to the gas supply pipe 5 is provided on the upper part of the purge pipe 12. The three-way pipe is used to connect the external gas source, the gas supply pipe 5 and the purge pipe 12. The function of the purge pipe 12 is to purge nitrogen into the protective housing 1 to ensure that the inside of the protective housing 1 is under low pressure, thereby reducing the entry of high humidity and high salt air.
