Description

Technical Field

[0001] This utility model relates to a fine water mist fire extinguishing device for locomotives. Background Technology

[0002] Currently, most of the fire-fighting equipment used on locomotives adopts the locomotive-specific fine water mist (two-gas, three-water) mode, which is commonly used for locomotive fire prevention and control. The mode belongs to the two-phase flow fine water mist system, and the core components include gas source devices such as high-pressure nitrogen cylinder groups, water supply cylinders such as water storage tanks, control valves, delivery pipelines, and fine water mist nozzles.

[0003] However, the interior of the new domestic electric locomotives is relatively compact and the locomotive interior is relatively small. The original fine water mist (two air and three water) mode requires a large installation space, which is extremely unsuitable for the space of the domestic electric locomotives with limited space and has insufficient installation compatibility.

[0004] Due to the limited space inside the locomotive, the existing fine water mist (two air and three water) mode, once installed, easily squeezes the layout space of other equipment, affecting the overall rationality of the equipment layout inside the locomotive. Its adaptability and practicality are insufficient, making it difficult to meet the basic requirements for locomotive equipment installation. Utility Model Content

[0005] To address the aforementioned problems, the purpose of this utility model is to provide a locomotive fine water mist fire extinguishing device that can meet the requirements of compact environments.

[0006] The technical solution for realizing this utility model is as follows:

[0007] The locomotive fine water mist fire extinguishing device includes two water cylinders and one high-pressure gas cylinder. The top surfaces of the two water cylinders and the high-pressure gas cylinder are equipped with a frame assembly, a water and gas collection valve block, and a zone control valve group. The frame assembly includes a base, with a No. 1 column set in the center of the base, which passes through a support platform located on the top surface of the water cylinders. The water and gas collection valve block and the zone control valve group are sequentially installed on the support platform.

[0008] The support platform is a non-closed isosceles trapezoidal shape composed of a left diagonal rod, a right diagonal rod, and a connecting rod. The tops of the two water bottles and the top of the high-pressure gas cylinder are connected to the support platform through connecting clamps.

[0009] The exposed ends of the left and right inclined rods of the support platform are each equipped with a No. 2 column and a No. 3 column that are connected to the base; the No. 2 column is placed between the two water bottles, and the No. 3 column is placed between the high-pressure gas cylinder and the water bottle adjacent to the high-pressure gas cylinder.

[0010] A first limiting baffle is provided on the outer surface of the first column, and a second limiting baffle is provided on the outer surface of the second and third columns; a first connecting block is provided at the top of the first limiting baffle and the top of the second limiting baffle, and a second connecting block is provided at the bottom of the first limiting baffle and the bottom of the second limiting baffle.

[0011] Multiple auxiliary support blocks are provided on the first limiting baffle between the first connecting block and the corresponding second connecting block; the exposed side of the first auxiliary support block is provided with an arc-shaped groove.

[0012] The water and air collection valve block includes a transition block and a frame. The frame is fixed to the top of the transition block with screws. The transition block is rectangular and has an internal air passage and a water passage. Both ends of the air passage and the water passage have through holes. The air passage has an air inlet on its side and two air outlets on its sides. The water passage has two water inlets on its bottom surface and a water outlet on its top surface. The water outlet is fixed inside the frame. A zone control valve assembly is also fixed inside the frame. One end of the zone control valve assembly is connected to the water outlet, and the other end of the zone control valve assembly is connected to the external pipe network.

[0013] The top of the No. 1 column is equipped with a lifting ring.

[0014] The above technical solution is adopted, which uses a combined fine water mist configuration with two sets of cylinders (one gas and two water) installed at different positions on the locomotive for joint control; the water cylinder and the high-pressure gas cylinder are precisely connected and fixed to form a stable triangular structure through a dedicated column and support platform, which significantly optimizes the overall layout of the system, greatly improves the structural compactness and space utilization, effectively adapts to the narrow installation scenario inside the locomotive, and meets the needs of equipment installation and use.

[0021] The locomotive fine water mist fire extinguishing device includes two water cylinders 1 and one high-pressure gas cylinder 2. A frame assembly 3, a water and gas collection valve block 4, and a zone control valve group 5 are mounted on the top surface of the two water cylinders and the high-pressure gas cylinder. The frame assembly includes a base 3.1, a central column 3.2, and a support platform 3.3 located on the top surface of the water cylinders. The water and gas collection valve block and the zone control valve group are sequentially installed on the support platform. The high-pressure gas cylinder supplies gas to the water cylinders through the water and gas collection valves, causing the water cylinders to spray water mist for fire extinguishing. The base, column, and support platform integrate the water cylinders and the high-pressure gas cylinder, making the structure compact and suitable for use in confined spaces. The (one gas, two water) cylinder group is jointly controlled, and the zone control valve allows one valve (multiple nozzles) to correspond to one area.

[0022] The support platform is a non-closed isosceles trapezoidal shape composed of a left diagonal rod 3.4, a right diagonal rod 3.5, and a connecting rod 3.6. The tops of the two water bottles and the top of the high-pressure gas cylinder are connected to the support platform via connecting clamps. One end of the connecting clamp is connected to the top of the cylinder, and the other end is fixed to the support platform with bolts, thus limiting the vertical movement of the cylinder.

[0023] The exposed ends of the left and right inclined rods of the support platform are each equipped with a second column 3.8 and a third column 3.9, which are connected to the base. The second column is placed between the two water bottles, and the third column is placed between the high-pressure gas cylinder and the adjacent water bottle. The columns are mainly used to fix the water bottles and the high-pressure gas cylinder.

[0024] A first limiting baffle 6 is provided on the outer surface of the first column, and a second limiting baffle 7 is provided on the outer surface of the second and third columns. A first connecting block 8 is provided at the top of the first limiting baffle and the top of the second limiting baffle, and a second connecting block 9 is provided at the bottom of the first limiting baffle and the bottom of the second limiting baffle. The first and second connecting blocks are installed in conjunction with the clamps 10. The first connecting block located at the top is used for the installation of one set of clamps, and the second connecting block located at the bottom is used for the installation of another set of clamps. The two sets of clamps make the connection more stable. When the bottle group is fixed by the clamps, the shock-absorbing strip is used to reduce vibration and friction.

[0025] Multiple auxiliary support blocks are provided on the first limiting baffle between the first connecting block and the corresponding second connecting block; the exposed side of the first auxiliary support block 11 is provided with an arc-shaped groove 12, which serves to provide auxiliary support for the bottle body. The second limiting baffle is also provided with an installation block at the position corresponding to the first auxiliary support block. The installation block is used in conjunction with the first auxiliary support to install the clamp. The multiple clamps are arranged from top to bottom to enhance the stability of fixing the three bottles.

[0026] The water and air collection valve block includes a transition block 4.1 and a frame 4.2. The frame is fixed to the top of the transition block with screws. The transition block is cuboid in shape and has an internal air passage and a water passage. Both ends of the air passage 4.3 and the water passage 4.4 have through holes. The air passage has an air inlet 4.5 on its side and two air outlets 4.6 on its sides. The water passage has two water inlets 4.7 on its bottom surface and a water outlet 4.8 on its top surface. The water outlet is fixed inside the frame. A zone control valve assembly is also fixed inside the frame. One end of the zone control valve assembly is connected to the water outlet, and the other end of the zone control valve assembly is connected to the external pipe network. Both ends of the gas and water circuits have through holes, which are plugged during operation. The gas and water circuits are connected by a high-pressure hose. Nitrogen supplied by the high-pressure gas cylinder enters the gas circuit through the inlet of the gas and water collection valve block via the high-pressure hose. After passing through two outlet joints and a pressure reducing device, it enters two water bottles. Using the siphon effect, water enters the water circuit through the two inlet ports of the gas and water collection valve block via the high-pressure hose. Then, it reaches the external zoned pipeline through the zoned valve group via the outlet port.

[0027] The top of the No. 1 column is equipped with a lifting ring 13. The lifting ring facilitates hoisting.
