Description

Technical Field

[0001] This utility model belongs to the technical field of fire sprinklers, and specifically relates to a retractable fire sprinkler device. Background Art

[0002] Fire sprinkler heads are used in fire sprinkler systems. When a fire occurs, they are self-activated within a predetermined temperature range or activated by control equipment according to a fire signal, and sprinkle water in the designed sprinkling shape and flow rate to implement fire extinguishing.

[0003] For example, the Chinese patent with the authorization announcement number CN213555064U discloses a fire sprinkler with adjustable sprinkling range, which can make the sprinkling range of the device adjustable and facilitate the use of users.

[0004] However, in the actual use process, there will be a phenomenon that the fire sources are distributed in a point-like manner, that is, the fire sources are only located on one side of the fire sprinkler. Existing fire sprinklers all spray fire-fighting water without dead angles in a 360-degree circle on the horizontal plane, forming a circular effective fire-extinguishing area. The fire-fighting water sprayed towards the fire source can effectively extinguish the fire, while the remaining fire-fighting water cannot extinguish the fire because it does not come into contact with the fire source. This part of the fire-fighting water is ineffective, resulting in a great waste of fire-fighting water. Summary of the Utility Model

[0005] The purpose of this utility model is to provide a retractable fire sprinkler device, which can shrink the effective water outlet area of the fire-fighting water, concentrate the fire-fighting water to extinguish the fire in the fire source area, improve the fire-extinguishing performance of the fire sprinkler, and reduce the waste of fire-fighting water.

[0006] The technical solution adopted by this utility model is specifically as follows:

[0007] A retractable fire sprinkler device includes a sprinkler water supply main body. One end of the sprinkler water supply main body is fixedly connected with a splash plate. A plurality of tooth ridges are fixedly connected to the periphery of the splash plate. An arc-shaped water baffle is installed outside the sprinkler water supply main body. The arc-shaped water baffle includes a retracted state and a water guiding state. When the arc-shaped water baffle is in the retracted state, it is separated from the splash plate. A plurality of water blocking areas arranged in a circular array are provided on the upper side of the splash plate and around the vitreous body. When the arc-shaped water baffle is in the water guiding state, it moves to at least one of the water blocking areas and abuts against the splash plate.

[0008] Furthermore, one structure of the arc-shaped water baffle is that it includes a support plate fixedly connected to the upper side of the sprinkler water supply main body. A plurality of vertically moving groups arranged in a circular array are fixedly connected to the support plate. Arc-shaped water baffle plates are fixedly connected to the plurality of vertically moving groups.

[0009] Further, the arc-shaped water baffle is vertically slidably connected to the support plate. The vertical movement group includes an electromagnet, a magnet, and a reset member that drives the arc-shaped water baffle to move and reset away from the splash tray. The magnet is fixedly connected to the arc-shaped water baffle, the electromagnet is fixedly connected to the support plate, and when the electromagnet is energized, it is magnetically repulsive to the magnet.

[0010] Further, a connection bracket is fixedly connected to the arc-shaped water baffle, the magnet is fixedly connected to the connection bracket, and two vertical rods are also fixedly connected to the connection bracket. The two vertical rods are vertically slidably connected to the support plate.

[0011] Further, top blocks are fixedly connected to the tops of the two vertical rods. The reset member is a return spring, and the return spring is sleeved on the outer side of the rod body of the vertical rod between the support plate and the top block.

[0022] In order to make the purpose and advantages of the present utility model clearer, the following specifically describes the present utility model in conjunction with embodiments. It should be understood that the following text only describes one or several specific implementation manners of the present utility model, and does not strictly limit the scope of protection specifically claimed by the present utility model.

[0023] As Figures 1-5 shown, a retractable fire sprinkler device includes a sprinkler water supply main body. One end of the sprinkler water supply main body is fixedly connected with a splash tray 5. A plurality of tooth ridges 6 are fixedly connected to the periphery of the splash tray 5. The sprinkler water supply main body can be connected to the sprinkler pipe 7 by threads or other means. When the sprinkler pipe 7 supplies water to the sprinkler water supply main body, the fire water output by the sprinkler water supply main body will shoot onto the splash tray 5 and then splash to the periphery of the fire sprinkler along the tooth ridges 6. The range that the fire water can splash to is the effective area where the fire sprinkler can extinguish the fire.

[0024] Here, as Figure 1 and Figure 3 shown, one structure of the sprinkler water supply main body is introduced here. Specifically, the sprinkler water supply main body includes a connecting pipe 1. The connecting pipe 1 can be threadedly connected to one end of the sprinkler pipe 7. A water outlet hole is opened at the central position of the connecting pipe 1. A lower bracket 3 is fixedly connected to the lower part of the connecting pipe 1. A glass body 4 for blocking the water outlet hole is fixedly connected to the lower bracket 3. When the external temperature of the glass body 4 exceeds the warning temperature of the glass body 4, the glass body 4 is heated and broken and no longer blocks the water outlet hole, then water can flow out automatically. The splash tray 5 is fixedly connected to the lower side of the lower bracket 3. The water flow discharged from the water outlet hole will directly shoot onto the upper side of the splash tray 5.

[0025] Among them, since the splash tray 5 and the tooth ridges 6 will direct the fire water ejected from the water outlet hole to the periphery of the fire sprinkler and supply water in a 360° non-dead-angle manner, in the actual use process, there will be a phenomenon that the fire source is only on one side of the fire sprinkler. In order to be able to concentrate the fire water to extinguish the fire source, the structure of the fire sprinkler is improved in this technical solution. Specifically, as Figures 1-2 and Figure 4As shown in the figure, an arc-shaped water baffle that can abut against the water splashing tray 5 is installed on the outer side of the spray water supply main body. The arc-shaped water baffle includes a contracted state and a water guiding state. When the arc-shaped water baffle is in the contracted state, it is separated from the water splashing tray 5 and does not interfere with the fire fighting water. A plurality of water blocking areas arranged in an annular array are provided on the upper side of the water splashing tray 5 and around the vitreous body 4. When the arc-shaped water baffle is in the water guiding state, it moves to at least one of the water blocking areas and abuts against the water splashing tray 5. At this time, the fire fighting water moving towards the arc-shaped water baffle will be blocked by the arc-shaped water baffle and flow towards the remaining areas. Since the arc-shaped water baffle is located at a position far from the fire source and the remaining areas are opposite to the fire source, the water flow can be concentrated in the fire source area.

[0026] One structure of the arc-shaped water baffle includes a moving group and an arc-shaped water blocking structure. The moving group can drive the arc-shaped water blocking structure to rotate around the vitreous body 4 in a circular motion and can also drive the vitreous body 4 to move vertically. The arc-shaped water blocking structure can be an arc-shaped plate, and extension plates that can extend and move can also be provided at both ends thereof, so as to adjust its opening angle and control the blocking range.

[0027] Among them, as Figure 2 and Figure 4 shown in the figure, one structure of the arc-shaped water baffle includes a support plate 2 fixedly connected to the upper side of the spray water supply main body. The support plate 2 is fixedly connected to the connecting pipe 1. A plurality of vertically moving groups arranged in an annular array are fixedly connected to the support plate 2. Arc-shaped water baffle plates 8 are fixedly connected to the plurality of vertically moving groups. At this time, when the vertically moving group drives the arc-shaped water baffle plate 8 to be separated from the water splashing tray 5, it is in the contracted state. When the vertically moving group drives the arc-shaped water baffle plate 8 to abut against the water splashing tray 5, it is in the water guiding state. By controlling the positions of the plurality of arc-shaped water baffle plates 8, an arc-shaped structure with different opening angles can be formed to adjust the water outlet range of the fire sprinkler.

[0028] Among them, the arc-shaped water baffle plate 8 is vertically slidably connected to the support plate 2. The vertically moving group includes an electromagnet 12, a magnet 13, and a reset member that drives the arc-shaped water baffle plate 8 to move in the direction away from the water splashing tray 5 for reset. Due to the existence of the reset member at the initial position of the arc-shaped water baffle plate 8, the arc-shaped water baffle plate 8 is separated from the water splashing tray 5. The magnet 13 is fixedly connected to the arc-shaped water baffle plate 8, and the electromagnet 12 is fixedly connected to the support plate 2. When the electromagnet 12 is energized, it is magnetically repelled from the magnet 13 and pushes the magnet 13 to drive the arc-shaped water baffle plate 8 to move towards the water splashing tray 5 until the arc-shaped water baffle plate 8 faces the water splashing tray 5. And when the power supply of the electromagnet 12 is accidentally cut off, under the action of the reset member, the arc-shaped water baffle plate 8 will automatically reset and no longer block the fire fighting water, ensuring the normal operation of the fire sprinkler and ensuring safety.

[0029] Specifically, as Figures 4-5As shown, a connecting bracket 14 is fixedly connected to the arc-shaped water baffle 8, a magnet 13 is fixedly connected to the connecting bracket 14, and two vertical rods 9 are also fixedly connected to the connecting bracket 14. The two vertical rods 9 are vertically slidably connected to the support plate 2 to control the moving direction of the arc-shaped water baffle 8. The tops of the two vertical rods 9 are both fixedly connected with top blocks 10. The reset member is a return spring 11. The return spring 11 is sleeved on the outer side of the rod body of the vertical rod 9 between the support plate 2 and the top block 10. By pushing the top block 10 with the elastic force of the return spring 11, the arc-shaped water baffle 8 can be automatically reset.

[0030] Among them, the shielding area of the arc-shaped water shield of the arc-shaped water baffle 8 can be limited on the main machine by the user in advance according to the on-site environment, or can be controlled according to the main machine. In this technical solution, it is preferably controlled according to the main machine, that is, a control module signal-connected to the main machine is installed on the support plate 2. The control module is electrically connected to the electromagnet 12 and can control the energization state of the electromagnet 12. When the main machine detects the position of the fire source through a camera or other fire source detection devices such as a temperature sensor and a smoke sensor, the arc-shaped water shield can be adjusted according to the main machine to make the fire sprinkler concentrate the fire water and spray it towards the fire source.

[0031] The working principle of this utility model is as follows: When a fire occurs, the external temperature exceeds the warning temperature of the glass body 4, and the glass body 4 is heated and broken, and no longer blocks the water outlet hole, then water can be discharged automatically. The water flowing out of the water outlet hole will directly hit the upper side of the splash plate 5, and then splash along the tooth ridges 6 to the periphery of the fire sprinkler, and extinguish the fire on the periphery of the fire sprinkler.

[0032] After the main machine detects the position of the fire source through the fire source detection device, the magnet 13 can be controlled to control the arc-shaped water baffle 8 far from the fire source to move downward and abut against the splash plate 5. At this time, since the arc-shaped water baffle 8 restricts the water flow, the ejected fire water will be concentrated and splashed towards the fire source area, so that the fire water can be concentrated to extinguish the fire in the fire source area, improve the fire extinguishing performance of the fire sprinkler, and reduce the fire water splashed towards the area without fire, reducing the waste of fire water.

[0033] The above are only the preferred embodiments of this utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of this utility model, several improvements and retouches can be made, and these improvements and retouches should also be regarded as the protection scope of this utility model. The structures, devices, and operation methods not specifically described and explained in this utility model, unless otherwise specified and limited, are implemented according to the conventional means in the art.
