Description

Technical Field

[0001] This utility model belongs to the field of fire sprinkler systems, specifically a multi-functional fire sprinkler device. Background Technology

[0002] Fire sprinkler systems, also known as automatic sprinkler fire extinguishing systems, are a widely used type of fixed fire protection facility.

[0003] Fire sprinkler systems mainly consist of sprinkler heads and water pipes. Among them, the sprinkler head is the core component of the fire sprinkler system, which has functions such as automatically spraying water to extinguish fires, controlling the spread of fire, and reducing the temperature at the fire scene. The sprinkler head is usually installed in a high position inside the building. When a fire occurs, the air near the fire sprinkler head heats up rapidly, which triggers the heat-sensitive element in the fire sprinkler head, releasing water from the fire pipe to extinguish the fire in the vicinity. However, existing fire sprinkler systems are all exposed to the outside and are easily affected by external objects, especially the relatively fragile heat-sensitive element, which is easily damaged by external objects.

[0004] Therefore, this utility model provides a multifunctional fire sprinkler system. Utility Model Content

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 3As shown, a multifunctional fire sprinkler device according to an embodiment of the present invention includes a sprinkler head 1; a support plate 12 is fixedly connected to the top of the sprinkler head 1; a pair of protective covers 13 are symmetrically installed in the middle of the support plate 12; a plurality of through slots 14 are opened in the middle of the protective cover 13; an insertion hole 15 is opened at the bottom of the protective cover 13; a connecting rod 16 is installed between the bottoms of the pair of protective covers 13; a pair of insertion rods 17 are fixedly connected to the bottom of the connecting rod 16; a round head 18 is fixedly connected to the top of the insertion rod 17; a rubber ring 19 is fixedly connected inside the insertion hole 15; a round plate 110 is fixedly connected to the top of the connecting rod 16; a water flow guiding mechanism is installed at the output end of the sprinkler head 1; during operation, the connecting rod 16 is placed between the bottoms of the pair of protective covers 13, then the pair of protective covers 13 are closed to surround the sprinkler head 1 and the tops of the pair of protective covers 13 rest on the support plate 12, then the connecting rod 16 is pushed upward and the pair of insertion rods 17 are inserted into the pair of insertion holes 15. When the pair of round heads 18 exceed the pair of rubber rings 19, the round heads 18 are blocked by the rubber rings 19 and will not easily detach from the socket 15. The connecting rod 16 connects the pair of protective covers 13 together, so that the pair of protective covers 13 will not easily fall off the spray head 1. When the spray head 1 is triggered by the external high temperature, the spray head 1 will spray high-pressure water. The water will impact the circular plate 110, causing the circular plate 110 to drive the pair of plug rods 17 down, thereby causing the pair of round heads 18 to pass through the pair of rubber rings 19 and detach from the inside of the socket 15. At this time, the bottom of the pair of protective covers 13 is no longer connected. Under the impact of the internal water, they will move away from both sides and fall off the spray head 1, so that the spray head 1 can spray normally. Through the above structure, the spray head 1 can be protected when it is not started, reducing the possibility of the heat-sensitive element in the middle of the spray head 1 being damaged by external objects, and the spray head 1 can be hidden to improve its aesthetics.

[0025] like Figures 1 to 5 As shown, the water flow guiding mechanism includes a support rod 2; the support rod 2 is fixedly connected to the inside of the output end of the spray head 1; a shaft 21 is rotatably connected to the middle of the support rod 2; a splash plate 22 is fixedly connected to the bottom of the shaft 21; multiple through holes 23 are opened in the middle of the splash plate 22; during operation, as the spray head 1 is started, high-pressure water will be sprayed out from the output end of the spray head 1, and the sprayed water will fall onto the splash plate 22. Part of the water will spray downwards through multiple splash plates 22, while another part of the water will splash around after falling onto the splash plate 22. Through the above structure, the lower part and the surrounding area of ​​the device can be sprayed simultaneously, improving the spray uniformity of the device.

[0026] like Figures 1 to 5As shown, an impeller 4 is fixedly connected to the middle of the shaft 21; the impeller 4 is located inside the output end of the spray head 1; multiple hoses 41 are fixedly connected to the bottom of the splash plate 22; the multiple hoses 41 are respectively connected to multiple through holes 23; during operation, as high-pressure water is sprayed from the output end of the spray head 1, the high-pressure water will impact the impeller 4 when passing through it, causing the impeller 4 to rotate, which in turn drives the splash plate 22 and the multiple hoses 41 to rotate, causing the bottom ends of the multiple hoses 41 to be dispersed towards different angles. When the water enters the multiple hoses 41 through the multiple through holes 23, it will be sprayed out in different directions through the other end of the multiple hoses 41. Through the above structure, the spray range and spray uniformity of the device can be further improved, thereby further improving the fire extinguishing effect.

[0027] like Figures 1 to 4 As shown, a first fixing rod 3 is fixedly connected to the middle of the shaft 21; an impact ball 31 is fixedly connected to the end of the first fixing rod 3; a spring rod 32 is fixedly connected to the bottom of the sprinkler head 1; and a bell 33 is fixedly connected to the bottom of the spring rod 32. During operation, when the shaft 21 rotates with the impeller 4, the impact ball 31 will rotate accordingly and strike the middle of the bell 33 during the rotation, causing the bell 33 to ring and alert the surrounding personnel. Through the above structure, when the sprinkler head 1 is started, an alarm sound can be automatically emitted to alert the surrounding personnel, reducing the occurrence of situations where the electronic warning device cannot alert the surrounding personnel in time due to fire malfunction, resulting in untimely evacuation of personnel. At the same time, it can guide firefighters, enabling them to reach the fire point more quickly for handling.

[0028] like Figure 5 As shown, a second fixing rod 5 is fixedly connected to the bottom of the through hole 23; a pull rope 51 is fixedly connected between multiple hoses 41; a pull rope 51 is also fixedly connected between the hose 41 near the second fixing rod 5 and the second fixing rod 5; during operation, when the water pressure is high and the impeller 4 rotates at a high speed, the bottom ends of multiple hoses 41 may be lifted to a high angle under centrifugal force, making it difficult for the water to be sprayed evenly under the spray head 1. By pulling the bottom ends of multiple hoses 41 with multiple pull ropes 51, it is difficult for the bottom ends of multiple hoses 41 to be lifted to a high angle, so that the water spray can be more even.

[0029] like Figure 3 As shown, a water-collecting membrane 6 is fixed to the bottom of the circular plate 110; a water inlet groove 61 is provided in the middle of the circular plate 110; during operation, when the spray head 1 starts spraying water, the water will fall into the water-collecting membrane 6 through the water inlet groove 61, so that the weight of the water increases the downward force of the circular plate 110, allowing the round head 18 to pass through the obstruction of the rubber ring 19 more quickly. Through the above structure, the situation where the round head 18 is difficult to break through the obstruction of the rubber ring 19 due to insufficient water impact force can be reduced, so that the pair of protective covers 13 can fall off more stably and quickly.

[0030] like Figure 1 As shown, the protective cover 13 is made of lightweight material; the connecting rod 16 and the circular plate 110 are also made of lightweight material; through the above structure, when the protective cover 13 and the connecting rod 16 fall from the spray head 1, the force of hitting surrounding people or objects can be reduced, thus reducing the occurrence of personnel injuries.

[0031] During operation, the connecting rod 16 is placed between the bottoms of a pair of protective covers 13. Then, the pair of protective covers 13 are closed to surround the spray head 1, with the tops of the protective covers 13 resting on the support plate 12. The connecting rod 16 is then pushed upwards, causing the pair of insert rods 17 to insert into a pair of sockets 15 until the pair of round heads 18 exceed the pair of rubber rings 19. At this point, the round heads 18 are blocked by the rubber rings 19 and will not easily detach from the sockets 15. The connecting rod 16 connects the pair of protective covers 13 together, preventing them from easily falling off the spray head 1. When the spray head 1 is triggered by external high temperatures, the spray head 1 will spray... High-pressure water is emitted, impacting the circular plate 110, causing it to lower a pair of insert rods 17. This causes a pair of round heads 18 to pass through a pair of rubber rings 19 and detach from the insertion hole 15. At this point, the bottom of the pair of protective covers 13 is no longer connected and, under the impact of the internal water, moves away from both sides and falls off the spray head 1, allowing the spray head 1 to spray normally. As the spray head 1 is activated, high-pressure water is sprayed from the output end of the spray head 1. The sprayed water falls onto the splash plate 22, with some of the water flowing downwards through multiple splash plates 22, while the rest falls onto the splash plate 22. The water splashes outwards from the spray plate 22. As the high-pressure water jet exits from the output end of the spray head 1, it impacts the impeller 4, causing it to rotate. This, in turn, rotates the spray plate 22 and multiple hoses 41, dispersing the bottom ends of the hoses 41 towards different angles. Water enters the hoses 41 through the through holes 23 and is then sprayed out in different directions from the other ends of the hoses 41. As the shaft 21 rotates with the impeller 4, the impact ball 31 rotates accordingly, striking the center of the bell 33 during its rotation, causing the bell to ring. 33 rings a bell to warn those around. When the water pressure is high and the impeller 4 rotates at a high speed, the bottom ends of multiple hoses 41 may be lifted to a high angle under centrifugal force, making it difficult for the water to be sprayed evenly under the spray head 1. Multiple pull ropes 51 pull the bottom ends of multiple hoses 41, making it difficult for the bottom ends of multiple hoses 41 to be lifted to a high angle. When the spray head 1 starts spraying water, the water will fall into the water-collecting membrane 6 through the water inlet 61, and the weight of the water will increase the downward force of the circular plate 110, so that the circular head 18 can pass through the obstruction of the rubber ring 19 more quickly.
