Description

Technical Field

[0001] The invention relates to the technical field of fire extinguishing equipment, in particular to a water spray fire extinguishing device for a thermal power plant and a use method thereof. Background Art

[0002] A water spray fire extinguishing device for a thermal power plant is an important equipment designed to ensure the safety of the thermal power plant. It is usually composed of a water storage container, a pressurizing system, a pipeline, a nozzle, etc. When in use, when the fire detector detects a fire signal, the pressurizing system is started, and the water in the water storage container is transported to the nozzle through the pipeline. The nozzle sprays water or water mist to cover the fire area, reduce the temperature, isolate the air to extinguish the fire. If the device can adjust the upper and lower spraying angles of the nozzle, it can better adapt to fires in different locations, improve fire extinguishing efficiency, and reduce the damage of fire to power plant equipment. The method of use includes installation and commissioning, daily maintenance, and startup operation when a fire occurs, so as to ensure that the device can play the greatest fire extinguishing role at critical moments and ensure the safe and stable operation of the thermal power plant.

[0003] During use, the existing device fails to adjust the upper and lower spraying angles of the nozzles, so there may be blind spots for fire extinguishing when extinguishing fires in power plants, and the fire area cannot be fully covered, thereby reducing the fire extinguishing effect. Especially in a complex power plant environment, the fire intensity and fire source heights at different locations are different, and fixed-angle nozzles are difficult to adapt to various situations. If the upper and lower spraying angles of the nozzles can be flexibly adjusted, then when facing fires in different locations, precise spraying can be performed according to actual conditions, thereby improving fire extinguishing efficiency, reducing damage to power plant equipment and facilities caused by fires, and ensuring safe and stable operation of power plants. Summary of the invention

[0004] The object of the present invention is to provide a water spray fire extinguishing device for a thermal power plant and a method of using the same to solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions: The cam is an angular block formed on the left and right sides of the U-shaped frame, and a latch is provided on the cam to lock the handle and lock the handle.

[0012] Furthermore, the top ends of a plurality of the sliding rods 2 are fixedly connected to a top plate, the top of the bottom plate is fixedly connected to two hydraulic cylinders, and the output ends of the two hydraulic cylinders are fixedly connected to the top plate.

[0013] The present invention has the following beneficial effects (1) The present invention provides an adjustment mechanism. When the nozzle is used, if the nozzle needs to be adjusted up and down, the pin on the U-shaped block can be removed first. In this way, the rectangular frame can drive the nozzle and cooperate with the two slide bars to slide in the arc groove on the U-shaped frame. Through this design, the nozzle can be more stable and reliable when adjusting the water spraying angle up and down. In addition, during the process of adjusting the angle of the nozzle, the rectangular frame on the nozzle will cooperate with the two rotating blocks 1, the two rotating blocks 2 and the two springs.

[0025] By setting a rotating mechanism, if the left and right water spraying angles of the nozzle 23 need to be adjusted, the motor 35 can be started. After the motor 35 is started, the small gear 37 will be driven by the rotating shaft 36 to engage with the large gear 33 on the outer wall of the turntable 32. In this process, due to the meshing action of the gears, the turntable 32 can rotate synchronously with the rotating shaft 36. At the same time, when the turntable 32 rotates, it will drive the nozzle 23 thereon to adjust the left and right spraying angles. Through such a setting, the flexibility of the device can be greatly improved, so that the nozzle 23 can flexibly adjust the left and right water spraying angles according to the actual fire extinguishing needs, better cover the fire area, and improve the effect and efficiency of fire extinguishing.

[0026] The fixing mechanism 4 includes a plurality of moving wheels 41 rotatably connected to the bottom of the base plate 293, a plurality of sliding rods 42 are slidably connected to the base plate 293, the bottom ends of the plurality of sliding rods 42 are fixedly connected to two limit rods 43, the two limit rods 43 are adapted to the plurality of moving wheels 41, the top ends of the plurality of sliding rods 42 are fixedly connected to a top plate 44, the top of the base plate 293 is fixedly connected to two hydraulic cylinders 45, and the output ends of the two hydraulic cylinders 45 are fixedly connected to the top plate 44.

[0027] By setting up a fixing mechanism, if the device needs to be limited to prevent it from unnecessary movement during the fire extinguishing process, the two hydraulic cylinders 45 can be started. After the two hydraulic cylinders 45 are started, they will drive the top plate 44 to move, and cooperate with the multiple sliding bars 42, so that the two limiting rods 43 on the multiple sliding bars 42 can limit the multiple moving wheels 41 at the bottom of the device, thereby ensuring that the device remains stable during fire extinguishing and the fire extinguishing effect will not be affected by unexpected movement.

When arriving at the designated fire extinguishing location, if the device needs to be limited to prevent it from unnecessary movement during the fire extinguishing process, the two hydraulic cylinders 45 can be started. After the two hydraulic cylinders 45 are started, they will drive the top plate 44 to move, and cooperate with the multiple sliding bars 42, so that the two limiting rods 43 on the multiple sliding bars 42 can limit the multiple moving wheels 41 at the bottom of the device, thereby ensuring that the device remains stable during fire extinguishing and the fire extinguishing effect will not be affected by unexpected movement.

[0029] When a fire extinguishing operation is required, the water pump 296 can be started.

[0030] Through this design, the nozzle 23 can be made more stable and reliable when adjusting the water spraying angle up and down, and in the process of adjusting the angle of the nozzle 23, the rectangular frame 22 on the nozzle 23 will cooperate with the two rotating blocks 29, the two rotating blocks 291 and the two springs 292. Under this cooperation, the nozzle 23 can automatically reset and maintain a flat shooting state after the angle adjustment is completed, thereby reducing the operation of manual reset. Through this setting, the problem of reduced fire extinguishing efficiency caused by the inability to adjust the angle of the nozzle 23 can be effectively reduced, thereby improving the effect and efficiency of fire extinguishing.

[0031] If it is necessary to adjust the left and right water spraying angles of the nozzle 23, the motor 35 can be started. After the motor 35 is started, the small gear 37 will be driven by the rotating shaft 36 to engage with the large gear 33 on the outer wall of the turntable 32. In this process, due to the meshing action of the gears, the turntable 32 can rotate synchronously with the rotating shaft 36. At the same time, when the turntable 32 rotates, it will drive the nozzle 23 thereon to adjust the left and right spraying angles. Through such a setting, the flexibility of the device can be greatly improved, so that the nozzle 23 can flexibly adjust the left and right water spraying angles according to the actual fire extinguishing needs, better cover the fire area, and improve the effect and efficiency of fire extinguishing.
