Description

Technical Field

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

[0002] Fire sprinklers are an important firefighting equipment used for fire extinguishing and fire control, which are usually installed on the ceiling inside the building or near potential fire risk areas, such as kitchens, electrical equipment rooms, etc. Fire sprinklers can automatically sense fire and release water or other chemical extinguishing agents to extinguish the flames or control the fire.

[0003] The patent with application number CN220778906U discloses a fire sprinkler that is easy to replace and maintain. The fire sprinkler is intended to solve the technical problem that the fire sprinkler is directly installed on the surface of the water inlet pipe in the prior art, which makes it impossible to replace the fire sprinkler in time when it is damaged, thereby making it impossible to extinguish the fire in time and causing economic losses. The fire sprinkler includes a fire sprinkler and a mounting plate. The lower surface of the mounting plate is connected to a limiting guide rail, and the side surface of the fire sprinkler close to the limiting guide rail is connected to a sliding block. When the fire sprinkler is damaged, the fastening bolt can be rotated, and the fastening bolt can move downward while rotating inside the first threaded hole. When the fastening bolt moves downward to the outside of the first threaded hole, the fire sprinkler can be pulled, so that the fire sprinkler can be removed, thereby facilitating the replacement of the fire sprinkler. Compared with the prior art, the utility model patent with application number CN220778906U solves the problem that the current fire sprinkler heads are directly installed on the surface of the water inlet pipe, resulting in the inability to replace the fire sprinkler heads in time when they are damaged, thus leading to the inability to extinguish the fire in time and causing economic losses.

[0004] However, in actual use, it is difficult to protect the fire sprinkler heads when not in use. When the fire sprinkler heads are not needed, they are exposed to the air for a long time and are at risk of being contaminated by dust, moisture, chemicals or other pollutants, making it difficult to ensure that they can operate normally when a fire occurs.

A fixing plate 12 is fixedly connected to the outside of the threaded sleeve 19. A fire sprinkler body 6 is provided outside the fixing plate 12.

[0026] A protective mechanism is provided on the outside of the protective box 1, and the protective mechanism includes a second connecting plate 10 arranged on the outside of the protective box 1, the outside of the second connecting plate 10 is rotatably connected to the first protective plate 7, the outside of the second connecting plate 10 is fixedly connected to the second gear 17, the outside of the second gear 17 is meshedly connected to the first gear 16, the outside of the first gear 16 is fixedly connected to the third connecting plate 11, the third connecting plate 11 is rotatably connected to the protective box 1, the outside of the third connecting plate 11 is rotatably connected to the second protective plate 8, the second rotating shaft 20 is rotatably connected to the protective box 1, the second connecting plate 10 is rotatably connected to the protective box 1, the first protective plate 7 is slidably connected to the protective box 1, and the second protective plate 8 is slidably connected to the protective box 1.

[0027] In this embodiment, when the fire sprinkler body 6 needs to be protected, the second rotating shaft 20 is rotated, and the second rotating shaft 20 drives the externally fixedly connected threaded rod 4 to rotate, and the threaded rod 4 causes the threaded sleeve 19 connected to the external thread to drive the position of the fixed plate 12 to rise and fall, so that the fixed plate 12 drives the fire sprinkler body 6 fixedly installed outside the water source 2 to be stored inside the protection box 1, so that the first protection plate 7 moves toward the middle, and the first protection plate 7 causes the externally rotatably connected second connecting plate 10 to rotate, and when the second connecting plate 10 rotates, the externally fixedly installed second gear 17 rotates;

[0028] The second gear 17 causes the first gear 16 that is meshed with the outside to rotate, and the first gear 16 drives the third connecting plate 11 that is fixedly connected to the outside to rotate, that is, the third connecting plate 11 will drive the second protective plate 8 that is rotatably connected to the outside to move toward the middle at the same time, that is, after the fire sprinkler body 6 is received in the protective box 1, the protective box 1 can be in a closed state, which is convenient for protecting the fire sprinkler body 6, ensuring that it can operate normally when a fire occurs, and improving the practicability of the device.

[0029] Embodiment 2: Figure 1-5 As shown, based on the first embodiment, a motor 15 is fixedly installed on the outside of the protection box 1, and a first rotating shaft 13 is provided at the output end of the motor 15. The first rotating shaft 13 and the protection box 1 are rotationally connected, and a first connecting plate 9 is fixedly connected to the outside of the first rotating shaft 13, and the first connecting plate 9 and the first protective plate 7 are rotationally connected. The first rotating shaft 13 is externally transmission-connected with a belt 14, and the belt 14 and the second rotating shaft 20 are transmission-connected. A plurality of telescopic rods 18 are fixedly connected to the inside of the protection box 1, and the side of the telescopic rods 18 away from the protection box 1 is fixedly connected to the fixed plate 12, a hose 3 is fixedly connected to the outside of the water source 2, and a self-priming pump 5 is fixedly installed on the outside of the hose 3, and the hose 3 and the protection box 1 are fixedly connected. The fire sprinkler body 6 installed on the outside of the hose 3 is detachably connected, and the water source 2 is preferably a water tank.

[0030] In this embodiment, the motor 15 fixedly installed outside the protection box 1 is started, and the motor 15 causes the first rotating shaft 13 set at the output end to rotate. The rotation of the first rotating shaft 13 drives the first connecting plate 9 fixedly connected to the outside to rotate, that is, the first connecting plate 9 drives the first protective plate 7 rotatably connected to the outside to move, so as to drive the protection mechanism to operate, and the rotation of the first rotating shaft 13 causes the belt 14 connected to the external transmission to be transmitted;

[0031] The belt 14 and the second rotating shaft 20 are also connected by transmission, that is, the belt 14 will cause the second rotating shaft 20 of the transmission connection to rotate, so that the storage mechanism can be operated. The multiple telescopic rods 18 fixedly connected inside the protective box 1 are fixedly connected to the fixed plate 12, so that the fixed plate 12 can remain stable when it is raised or lowered. When the fixed plate 12 drives the fire sprinkler body 6 to be stored inside the protective box 1, the hose 3 fixedly connected to the outside of the fire sprinkler body 6 can be rolled up inside the protective box 1, and the self-priming pump 5 can spray the water inside the water source 2 from the fire sprinkler body 6 through the hose 3, thereby achieving the effect of extinguishing the fire.
