Technical Field
[0001] This utility model relates to fire extinguishing devices on power generation ships, and in particular to a fire extinguishing device for a gas turbine on a power generation ship. Background Technology
[0002] In power generation ships, gas turbines are the core power equipment. Their operating environment is high temperature, high pressure and flammable. The fire extinguishing system of power generation ships is a key issue to be considered in the design. Since gas turbines are the most important equipment in power generation ships, the fire extinguishing protection system for this equipment is of paramount importance in the design.
[0003] Traditional fire suppression systems on power generation ships typically require a separate room, known as a gas cylinder room. Given the limited space and poor transportation conditions on board, fixed fire suppression systems are not only inconvenient to transport and install, but also occupy a large amount of space. This is especially true on space-constrained vessels like power generation ships, where space utilization efficiency is extremely important. The fixed layout of traditional fire suppression systems makes it difficult to flexibly adjust to the location of the gas turbine. Furthermore, traditional fire suppression systems suffer from technical problems such as complex structure, high production costs, limited maintenance space, and high maintenance difficulty.
[0004] Therefore, separating the fire suppression system of the gas turbine inside the power generation ship to simplify, integrate, and make the large fire suppression system more flexible has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention
[0005] The technical problem to be solved by this utility model is to provide a fire extinguishing device for a gas turbine generator ship, with the aim of separating the fire extinguishing device independently, reducing the space occupied, lowering costs, facilitating maintenance, and effectively utilizing the space on the ship.

A plug is provided on one side of the gas collection pipe, and a fire extinguishing medium outlet flange is provided on the other side of the gas collection pipe. Each gas collection pipe is installed on the bracket.

[0009] Preferably, the aforementioned starting gas cylinder is mounted on a longitudinal support column on one side of the bracket via a tie rod, and a CO2 concentration detector is installed at the lower part of the longitudinal support column on the other side of the bracket.
[0010] Preferably, a gravity transmitter is installed on the longitudinal support on the same side above the CO2 concentration detector.
[0011] Preferably, the fire extinguishing bottle is fixedly installed on the lower horizontal support of the bracket, and each gas collecting pipe is installed on the upper horizontal support plate of the bracket.
[0012] Preferably, the second bottle head valve is equipped with a third pressure gauge and a second pressure switch.
[0013] Preferably, a second pressure gauge is provided on the first bottle head valve.
[0014] Preferably, the aforementioned hose is equipped with a one-way valve.

[0026] The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.
[0027] like Figure 1 and Figure 2 As shown, this utility model discloses a fire extinguishing device for a gas turbine used in a power generation vessel. Its structure is as follows: A grid-shaped mesh support 15 is fixedly installed on a base 4. A fire extinguishing bottle 16 and a starting gas cylinder 21 are provided on the base 4. The fire extinguishing bottle 16 is fixedly installed on the lower horizontal support of the support 15. The starting gas cylinder 21 is installed on a longitudinal support on one side of the support 15 via a tie rod. A CO2 concentration detector 22 is installed at the lower part of the longitudinal support on the other side of the support 15. A gravity transmitter 13 is installed on the longitudinal support on the same side above the CO2 concentration detector 22. A second cylinder head valve 20 is provided at the nozzle of the starting gas cylinder 21. Figure 4 As shown, the second cylinder head valve 20 is equipped with a solenoid valve 17, a third pressure gauge 18, and a second pressure switch 19. The second cylinder head valve 20 is connected to the first cylinder head valve 10 on the nozzle of each fire extinguishing bottle 16 via the gas pipe 11. The first cylinder head valve 10 is equipped with a second pressure gauge 12. The first cylinder head valve 10 is connected to its respective gas collection pipe 23 via each hose 9. Figure 3 As shown, each hose 9 is equipped with a one-way valve 8, and one side of the gas collection pipe 23 is equipped with a plug 1. The other side of the gas collection pipe 23 is a fire extinguishing medium outlet flange 24. Each gas collection pipe 23 is fixedly installed on the upper horizontal support plate of the bracket 15. Each gas collection pipe 23 is equipped with its own first pressure gauge 6 and first pressure switch 5. The upper horizontal support plate of the bracket 15 is equipped with an indicator light 2, an audible and visual alarm light 3, a gravity sensor 7, and a lifting lug 14.
[0028] The structure and function of each component of this utility model, as well as the working principle of the entire device, are as follows:
[0029] The starting gas cylinder 21 contains a starting gas medium for starting the fire extinguishing bottle 16, which can be nitrogen or other gases. The fire extinguishing bottle 16 contains the extinguishing medium CO2. When the second cylinder head valve 20 and the solenoid valve 17 at the top of the cylinder 21 are opened, the starting gas cylinder 21 releases the starting gas. The starting gas passes through the gas pipe 11 to open the first cylinder head valve 10 at the top of the fire extinguishing bottle 16, thus opening the fire extinguishing bottle 16. The extinguishing medium enters the respective gas collection pipe 23 through the hose 9 and the one-way valve 8, and then extinguishes the fire through the outlet flange 24.
[0030] The aforementioned second cylinder head valve 20 is used to seal the starting gas cylinder 21 and to install the solenoid valve 17, the second pressure switch 19, and the third pressure gauge 18. The solenoid valve 17 is used to control the release of the gas medium from the starting gas cylinder 21, the pressure gauge 18 is used to indicate whether the starting gas cylinder 21 is under-pressured, and the pressure switch 19 is used to provide feedback on whether the starting gas cylinder 21 has been released.
[0031] Multiple fire extinguishing bottles 16 can be set according to the size of the protected area, and each fire extinguishing bottle 16 contains CO2 extinguishing agent.
[0032] The first cylinder head valve 10 is used to seal the fire extinguishing bottle 16. A second pressure gauge 12 is installed on the first cylinder head valve 10 to indicate whether the fire extinguishing bottle 16 is under-pressured. The hose 9 is used to deliver CO2 extinguishing medium and features buffering and easy installation. The one-way valve 8 is used to prevent backflow of the medium in the gas collecting pipe 23. The first pressure switch 5 and the first pressure gauge 6 are used to indicate whether the fire extinguishing bottle 16 has been released and the release pressure.
[0033] The CO2 concentration detector 22 is used to detect the CO2 gas concentration in the environment surrounding the fire extinguisher 16 and to measure whether there is a CO2 leak in the fire extinguisher 16. The gravity sensor 7 is used to detect whether the fire extinguisher 16 is under-voltage. The gravity transmitter 13 is used to send the signal detected by the gravity sensor 7 to the control cabinet.
[0034] The aforementioned air pipe 11 is made of copper. The lifting lug 14 is used for moving and hoisting the entire device. The audible and visual alarm light 3 is red and blue, with a sound intensity of no less than 5W, and the indicator light 2 is used to display the operating status of the entire device.
