Description

Technical Field

[0001] This utility model relates to the field of fire sprinkler technology, and more specifically to a corrosion-resistant and impact-resistant fire sprinkler. Background Technology

[0002] With the development of the Industrial Revolution, urban buildings became denser and more complex, and the risk of fire increased accordingly. In the 19th century, some manually controlled fire sprinklers appeared. These sprinklers required manual observation of the fire and manual activation. In the 20th century, automatic sprinklers began to appear. They achieved automatic control through mechanical principles and could detect the occurrence of fire in the first instance, such as when the temperature rises or smoke is generated, and quickly start spraying water, greatly reducing the possibility of fire spreading.

[0003] However, the existing sprinkler activation mechanism, which is easily corroded by splashed liquids or accidentally activated when installed in some large equipment, causes the fire sprinklers to suddenly start when water is not needed for fire extinguishing. This not only wastes water resources but may also cause unnecessary chaos and trouble on site.

[0004] At the same time, the spray range of existing fire sprinklers is relatively limited. If the fire spreads beyond the spray area of ​​the fire sprinklers, it will be impossible to effectively cover and extinguish the entire fire area.

[0005] Therefore, in order to solve the above problems, this application provides a corrosion-resistant and impact-resistant fire sprinkler head. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a corrosion-resistant and impact-resistant fire sprinkler head to solve the problems existing in the background art.

[0007] This utility model provides the following technical solution: a corrosion-resistant and collision-resistant fire sprinkler head, including an installation component and a water outlet component installed on the installation component, a nozzle component installed on the water outlet component, a splash component installed on the nozzle component, and a positioning component provided inside the installation component;

[0008] Preferably, the mounting assembly includes a protective cover, a threaded alloy sleeve, and a sliding groove, wherein the threaded alloy sleeve is fixedly mounted on the top of the protective cover and communicates with its inner cavity, and the inner wall of the protective cover has four circumferentially distributed sliding grooves.

[0009] Preferably, the water outlet assembly includes a water delivery hose, a liquid storage pipe, a clamp, and positioning posts. One end of the water delivery hose is fixedly installed on the top of the protective cover and connected to a threaded alloy sleeve. The other end of the water delivery hose is fixedly installed on the top of the liquid storage pipe and connected to its inner cavity. The clamp is fixedly sleeved on the outside of the liquid storage pipe. Four positioning posts evenly distributed in a circle are fixedly installed on the side wall of the clamp. The end of the positioning post away from the clamp is slidably connected to the protective cover through a sliding groove. When the temperature sensing component in the positioning assembly bursts, the positioning post and the parts fixedly installed on the positioning post move downward along the sliding groove under the action of gravity. At this time, the entire positioning assembly extends to the outside of the lower part of the protective cover.

[0010] Preferably, the nozzle assembly includes a fixing plate, reinforcing ribs, a lower cover, and a water-blocking plug. The fixing plate is fixedly sleeved on the bottom of the liquid storage tube. Reinforcing ribs evenly distributed around the circumference are fixedly installed at the connection between the fixing plate and the liquid storage tube. The lower cover is fixedly installed on the bottom of the liquid storage tube. The water-blocking plug is movably snapped onto the bottom of the lower cover. When the temperature sensing component in the positioning assembly bursts, the water-blocking plug falls off from below the lower cover under its own weight and the water pressure inside the liquid storage tube.

[0011] Preferably, the water splashing assembly includes a connecting frame, a positioning block, a rotating disk, splashing blades, and a guide plate. The connecting frame is fixedly installed in a mirror image at the bottom of the fixed disk, and a positioning block is fixedly installed between the two connecting frames. The upper end of the rotating disk is rotatably engaged with the positioning block. Splashing blades that are evenly distributed in a circle are fixedly installed on the edge of the rotating disk. A guide plate is fixedly installed between every two splashing blades. When high-pressure water is sprayed from the bottom of the lower cover and sprayed above the splashing blades, the high-pressure jet strikes the guide plate, thereby driving the rotating disk and the components fixedly installed on the rotating disk to rotate along the main axis of the rotating disk. Under the action of rotation, the water strikes the splashing blades and splashes to a more distant area.

[0012] Preferably, the positioning assembly includes a slider, a first hinge, a second hinge, a third hinge, a fourth hinge, a limiting block, a support member, and a temperature-sensitive glass column. Except for the temperature-sensitive glass column, all components of the positioning assembly are symmetrically distributed on both sides of the glass column. The temperature-sensitive glass column is engaged between the water-blocking plug and the positioning block. The slider is located below the positioning column and is slidably connected to the protective cover via a groove. The first hinge is fixedly mounted on the slider. One end of the second hinge is hinged to the first hinge, and the other end is hinged to the third hinge. The third hinge is located away from the limiting block. One end of the positioning block is hinged to the fourth hinge, which is located on the lower side of the slider and fixedly installed on the inner wall of the protective cover. The support members are attached to the temperature-sensing glass column in pairs. The limiting block is fixedly installed on the support member. The end of the limiting block away from the support member is rotatably engaged on the hinge axis between the second hinge and the third hinge. When the temperature in the current area is too high, the temperature-sensing glass column bursts, the support member loses its support point, and the first hinge, second hinge, third hinge and fourth hinge rotate along the hinge axis at their respective connection points. The slider moves downward along the slide groove under the action of gravity.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] The design of the protective cover and positioning components prevents the internal heat-sensing glass column from shattering due to external liquid corrosion or accidental contact, thus saving water resources and improving the practicality of the nozzle. At the same time, the guide plate and rotating disc in the splashing assembly expand the spray range of the nozzle and improve fire extinguishing efficiency. Attached Figure Description

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The corrosion-resistant and collision-resistant fire sprinkler head involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Reference Figure 1 and Figure 2 This utility model provides a corrosion-resistant and collision-resistant fire sprinkler head, including an installation component 1 and a water outlet component 2 installed on the installation component 1. A nozzle component 3 is installed on the water outlet component 2, a splash component 4 is installed on the nozzle component 3, and a positioning component 5 is provided inside the installation component 1.

[0021] Reference Figure 1 and Figure 2 The mounting assembly 1 includes a protective cover 101, a threaded alloy sleeve 102, and a slide groove 103. The threaded alloy sleeve 102 is fixedly installed on the top of the protective cover 101 and communicates with its inner cavity. The inner wall of the protective cover 101 has four slide grooves 103 distributed in a circular pattern.

[0022] Reference Figure 2 The water outlet assembly 2 includes a water supply hose 201, a liquid storage pipe 202, a clamp 203, and positioning posts 204. One end of the water supply hose 201 is fixedly installed on the top of the protective cover 101 and connected to the threaded alloy sleeve 102. The other end of the water supply hose 201 is fixedly installed on the top of the liquid storage pipe 202 and connected to its inner cavity. The clamp 203 is fixedly sleeved on the outside of the liquid storage pipe 202. Four positioning posts 204 are fixedly installed on the side wall of the clamp 203 in a circumferentially evenly distributed manner. The end of the positioning post 204 away from the clamp 203 is slidably connected to the protective cover 101 through the slide groove 103. When the component used for temperature sensing in the positioning assembly 5 bursts, the positioning post 204 and the parts fixedly installed on the positioning post 204 move downward along the slide groove 103 under the action of gravity. At this time, the entire positioning assembly 5 extends to the outside of the lower part of the protective cover 101.

[0023] Reference Figure 2The nozzle assembly 3 includes a fixed plate 301, a reinforcing rib 302, a lower cover 303, and a water-blocking plug 304. The fixed plate 301 is fixedly sleeved on the bottom of the liquid storage tube 202. The reinforcing rib 302, which is evenly distributed in a circle, is fixedly installed at the connection between the fixed plate 301 and the liquid storage tube 202. The lower cover 303 is fixedly installed on the bottom of the liquid storage tube 202. The water-blocking plug 304 is movably snapped into the bottom of the lower cover 303. When the component used for temperature sensing in the positioning assembly 5 bursts, the water-blocking plug 304 falls off from below the lower cover 303 under its own weight and the water pressure inside the liquid storage tube 202.

[0024] Reference Figure 2 The water splashing assembly 4 includes a connecting frame 401, a positioning block 402, a rotating disk 403, splashing blades 404, and a guide plate 405. The connecting frame 401 is fixedly installed in a mirror image at the bottom of the fixed disk 301. The positioning block 402 is fixedly installed between the two connecting frames 401. The upper end of the rotating disk 403 is rotatably engaged with the positioning block 402. The edge of the rotating disk 403 is fixedly installed with splashing blades 404 evenly distributed in a circle. Each pair of splashing blades 404 is fixedly installed with a guide plate 405 spaced apart. When high-pressure water is sprayed from the bottom of the lower cover 303 and sprayed above the splashing blades 404, the high-pressure jet hits the guide plate 405, thereby driving the rotating disk 403 and the components fixedly installed on the rotating disk 403 to rotate along the main shaft of the rotating disk 403. Under the action of rotation, the water hits the splashing blades 404 and splashes to a more distant area.

[0025] Reference Figure 2 and Figure 3The positioning component 5 includes a slider 501, a first hinge 502, a second hinge 503, a third hinge 504, a fourth hinge 505, a limiting block 506, a support member 507, and a temperature-sensing glass column 508. Except for the temperature-sensing glass column 508, all other components of the positioning component 5 are symmetrically distributed on both sides of the temperature-sensing glass column 508. The temperature-sensing glass column 508 is engaged between the water-blocking plug 304 and the positioning block 402. The slider 501 is located below the positioning column 204 and is slidably connected to the protective cover 101 via a sliding groove 103. The first hinge 502 is fixedly mounted on the slider 501. One end of the second hinge 503 is hinged to the first hinge 502, and the other end is hinged to the third hinge 504. The third hinge 504 is located away from the limiting block 506. One end of the position block 506 is hinged to the fourth hinge 505. The fourth hinge 505 is located on the lower side of the slider 501 and is fixedly installed on the inner wall of the protective cover 101. The support members 507 are attached to the temperature-sensing glass column 508 in pairs. The limiting block 506 is fixedly installed on the support member 507. The end of the limiting block 506 away from the support member 507 is rotatably engaged on the hinge axis between the second hinge 503 and the third hinge 504. When the temperature of the current area is too high, the temperature-sensing glass column 508 bursts, the support member 507 loses its support point, and the first hinge 502, the second hinge 503, the third hinge 504 and the fourth hinge 505 rotate along the hinge axis at their respective connection points. The slider 501 moves downward along the slide groove 103 under the action of gravity.

[0026] The working principle of this utility model is as follows: When using this fire sprinkler head, the entire component is installed at the water source interface through the threaded alloy sleeve 102. When the temperature in the current area is too high, the temperature-sensing glass column 508 bursts, the support member 507 loses its support point, and the first hinge 502, the second hinge 503, the third hinge 504, and the fourth hinge 505 rotate along the hinge axis at their respective connections. The slider 501 moves downward along the slide groove 103 under the action of gravity, and the positioning post 204 and the components fixedly installed on the positioning post 204 also move downward along the slide groove 103 under the action of gravity. As the positioning component 5 extends to the outside of the protective cover 101, the temperature-sensing glass column 508 bursts. At the same time, the water plug 304 falls off from below the lower cover 303 under its own weight and the water pressure inside the liquid storage tube 202. High-pressure water jets from the bottom of the lower cover 303 and sprays onto the splash blade 404. Simultaneously, the high-pressure jet hits the guide plate 405, thereby driving the rotating disk 403 and the components fixedly installed on the rotating disk 403 to rotate along the main axis of the rotating disk 403. Under the action of rotation, the water jet hits the splash blade 404 and splashes to a more distant area.
