Description

Technical Field

[0001] The utility model relates to the technical field of subway carriage fire extinguishing, and more specifically, to a subway emergency fire extinguishing spraying device. Background Art

[0002] Subway emergency fire-fighting spraying refers to the process of rapidly activating the automatic sprinkler system to control and extinguish a fire once it breaks out inside a train car. Currently, some automated fire-fighting systems in subway cars spray water over a wide area, failing to target the fire's source. This leads to high costs and an inefficient fire-fighting process, hindering widespread adoption.

[0003] After searching, a Chinese patent with announcement number CN219681523U discloses an automatic fire extinguishing device for subway cars. In this utility model, a water pump discharges water in a water tank into a circular tube through an L-shaped hose, and the water is discharged into a corresponding nozzle through a corresponding solenoid valve. The nozzle sprays water to extinguish the fire, thus forming an automatic fire extinguishing device for subway cars. When a fire occurs, the nozzle of the automatic fire extinguishing device for subway cars will not spray water over a large area, but can spray water in a targeted manner at the fire site. The cost is low, the fire extinguishing process is reasonable, and it is conducive to promotion.

[0004] When the above-mentioned fire extinguishing device is in use, water is discharged into the corresponding nozzle through the corresponding solenoid valve, and the nozzle sprays water to extinguish the fire. However, multiple solenoid valves need to be set up, and the corresponding solenoid valves need to be controlled by a controller. The structure is complex and the cost of use is high. Utility Model Content

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a subway emergency fire extinguishing spray device, comprising a mounting frame, one side of the mounting frame is fixedly connected to a connecting pipe, a solenoid valve is fixedly installed on the connecting pipe, a spray assembly is arranged inside the mounting frame, the spray assembly comprises a water pipe, a water tank and a nozzle, a moving assembly is arranged outside the water tank, the moving assembly comprises a motor, a screw rod, a slide rod, two slides and a U-shaped plate, the motor is fixedly mounted on one side of the mounting frame, and the output shaft end of the motor is fixedly connected to the screw rod, the other end of the screw rod is movably connected to the mounting frame through a bearing, both ends of the slide rod are fixedly connected to the mounting frame, the two slides are movably mounted on the screw rod and the slide rod, and the opposite sides of the two slides are fixedly connected to the U-shaped plate.

[0007] Furthermore, both ends of the water pipe are fixedly connected to the connecting pipe and the water tank respectively, and the bottom end of the water tank is fixedly connected to the nozzle.

[0008] Furthermore, a rotating assembly is provided on the U-shaped plate, and the rotating assembly includes a second motor, a first rotating shaft, a first bevel gear, a second bevel gear and two second rotating shafts.

[0010] Furthermore, side panels are fixedly connected to the top edges of both sides of the installation frame.

[0011] It can be seen that in the above technical solution, the two side panels are mounted on the top of the subway car by means of bolts, so that the mounting frame is fixed to the top of the subway car.

[0012] Furthermore, a sensor is fixedly installed at the center position of the top of the installation frame.

[0013] It can be seen that the above technical solution facilitates the monitoring of subway cars.

[0014] Furthermore, a baffle is fixedly connected to the bottom edge of one inner side of the installation frame.

[0015] It can be seen that in the above technical solution, when the water-based fire extinguishing agent is not sprayed, the nozzle is shielded by the baffle.

[0017] 1. In the present invention, when a fire occurs, the motor and the solenoid valve are started, the motor drives the screw to rotate, and the screw can drive the U-shaped plate to move horizontally, thereby driving the water tank and the sprinkler to move horizontally, and the sprinkler moves to the fire location.

The structure is simple and the use cost is effectively reduced.

[0018] 2. The utility model drives the first rotating shaft to rotate through the operation of the second motor, thereby driving the first bevel gear to rotate. Since the first bevel gear is engaged with the second bevel gear, the first bevel gear can drive the second bevel gear to rotate, thereby driving the second rotating shaft to rotate, and then driving the water tank and the sprinkler head to rotate. The inclination angle of the sprinkler head is adjusted according to demand, thereby adjusting the spraying angle of the water-based fire extinguishing agent. The structure is simple and easy to use.

[0029] Among them, the second motor 801 is started, and the second motor 801 drives the first rotating shaft 802 to rotate, thereby driving the first bevel gear 803 to rotate. Since the first bevel gear 803 is engaged with the second bevel gear 804, the first bevel gear 803 can drive the second bevel gear 804 to rotate, thereby driving the second rotating shaft 805 to rotate, and then driving the water tank 702 and the nozzle 703 to rotate.
