Description

Technical Field

[0001] The utility model relates to the technical field of fire fighting, in particular to a fire fighting sprinkler device. Background Art

[0002] Firefighting is to eliminate hidden dangers and prevent disasters (that is, a general term for preventing and solving man-made, natural and accidental disasters encountered by people in the process of life, work and study). In a narrow sense, it means extinguishing fires. As the floors are getting higher and higher, once a fire occurs, firefighters will not be able to extinguish the fire in time. In order to improve the safety performance of some places, it is necessary to install sprinkler devices to eliminate hidden dangers.

[0003] After searching, a Chinese patent discloses a fire sprinkler device (authorization announcement number CN215995415U), including a fire-fighting frame, an adjustable sprinkler frame is fixedly arranged in the middle of the top of the fire-fighting frame, a square adjusting slide hole is opened in the middle of the top of the adjustable sprinkler frame, an adjusting slider is slidably connected inside the square adjusting slide hole, a sprinkler main pipe is fixedly arranged at the bottom of the adjusting slider, a plurality of evenly distributed sprinkler heads are fixedly connected at the bottom of the sprinkler main pipe, and an adjusting chassis is fixedly arranged on the top of the adjusting slider. Although the patented technology adds an adjustable sprinkler frame, when a fire occurs indoors, the servo motor can drive the sprinkler main pipe to flexibly move and adjust on the adjustable sprinkler frame so that the sprinkler head faces the flame, thereby quickly and efficiently extinguishing the initial flame and avoiding causing a larger fire. The operation is flexible and fast, and the pertinence is strong, which improves the safety of fire fighting and reduces the waste of water resources. The operation is simple and convenient.

[0004] However, the above device still has some shortcomings in actual use. The most obvious one is that the above fire sprinkler device only uses a row of sprinkler heads to achieve fire extinguishing work, cannot carry out accurate fire extinguishing, and is not very targeted. A row of sprinkler heads will not only extinguish the fire point, but also cause objects in other areas to get wet, thereby failing to achieve the best use effect of the device. Utility Model Content

A row of sprinkler heads will not only extinguish the fire at the fire point, but also cause objects in other areas to get wet, thereby failing to achieve the best use effect of the device. The main purpose of the utility model is to provide a fire sprinkler device.

[0006] The technical solution of the utility model is as follows: a fire sprinkler device comprises a fixed frame, both sides of the inner wall of the fixed frame are provided with installation grooves, wherein a threaded rod is rotatably connected to the inside of one of the installation grooves, and a fixing rod is fixedly connected to the inside of the other installation groove, a lower fixing box is threadedly connected to the outer side of the threaded rod, the lower fixing box is slidably connected to the fixing rod, both ends of the interior of the lower fixing box are rotatably connected to pulleys, a transmission belt is transmission-connected between the two pulleys, a transmission block is fixedly connected to the outer side of the transmission belt, a fixed pipe is fixedly connected to the interior of the transmission block, the bottom end of the fixed pipe is fixedly connected to a bellows, the bottom end of the bellows is fixedly connected to a fire sprinkler, a monitoring mechanism is arranged inside the fixed frame, and an anti-winding mechanism is arranged at the top of the lower fixing box.

[0007] By adopting the above technical solution, the rotation of the threaded rod can drive the lower fixed box to move left and right, and the rotation of the pulley can drive the transmission belt to rotate, and then drive the transmission block to move, thereby driving the fixed pipe and the fire sprinkler to move forward and backward, and then the fire sprinkler can be moved forward and backward and left and right, so that the position of the fire sprinkler can be accurately controlled.

[0008] As a preferred implementation, the monitoring mechanism includes a controller fixedly mounted on one side of the inner wall of the fixed frame, and infrared fire detectors are fixedly mounted on both ends of the bottom of the fixed frame.

[0009] By adopting the above technical solution, through the setting of infrared fire detectors, the flame sensor inside the detector uses infrared rays to detect the heat radiation generated by the fire, so that the fire can be discovered quickly and accurately, and the fire information can be transmitted to the controller.

[0010] As a preferred embodiment, the anti-winding mechanism includes an upper fixed box fixedly connected to the top of a lower fixed box, a limiting groove is provided between the upper fixed box and the lower fixed box, a disc is fixedly connected to the outer side of the fixed tube, the fixed tube fits with the inner wall of the limiting groove, an elastic hose is fixedly connected to the top of the fixed tube, and the end of the elastic hose away from the fixed tube is connected to the external pump body.

[0011] By adopting the above technical solution, the fixed pipe can be limited by the coordinated use of the disc and the limiting groove to cooperate with the movement of the transmission block and the fire sprinkler, thereby avoiding the entanglement of the elastic hose and storing the elastic hose through the upper fixed box.

[0012] As a preferred embodiment, a limiting groove used in conjunction with a fixing pipe is opened inside the lower fixing box, a fixing plate is fixedly connected to the outside of the fixing pipe and below the limiting groove, an electric telescopic rod is rotatably connected to the bottom end of the fixing plate, and a piston rod of the electric telescopic rod is rotatably connected to the fire sprinkler.

[0013] By adopting the above technical solution, as the piston rod of the electric telescopic rod is extended and retracted, the angle of the fire sprinkler head can be adjusted to adapt to fire points at different angles for fire extinguishing operations.

[0014] As a preferred implementation manner, a first servo motor is fixedly mounted on the inner wall of one of the mounting grooves, and an output shaft of the first servo motor is fixedly connected to the threaded rod.

[0015] By adopting the above technical solution, the threaded rod can be driven to rotate.

[0016] As a preferred embodiment, a second servo motor is fixedly mounted on the bottom end of the lower fixed box, and an output shaft of the second servo motor extends into the interior of the lower fixed box and is fixedly connected to the central axis of the pulley.

[0017] By adopting the above technical solution, the pulley can be driven to rotate.

[0018] Compared with the prior art, the advantages and positive effects of the utility model are:

[0019] In the utility model, through the setting of the monitoring mechanism, the ignition point of the fire can be accurately judged, and the threaded rod can be controlled to rotate. Through the rotation of the threaded rod, the lower fixed box can be driven to move left and right, and through the setting of the fixed rod, the lower fixed box is relatively stable during the movement and is not prone to shaking. Through the rotation of the pulley, the transmission belt can be driven to rotate, and then the transmission block can be driven to move, thereby driving the fixed pipe and the fire sprinkler to move forward and backward, and then the fire sprinkler can be moved forward and backward and left and right, so that the position of the fire sprinkler can be accurately adjusted, so that accurate fire extinguishing can be carried out, and it is more targeted.
