Description

Technical Field

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

[0002] The fire sprinkler is installed on the wall or ceiling and is connected to a water network pipeline filled with pressure. When a fire occurs, after the glass tube in the sprinkler is exposed to high temperature, the liquid inside will start to expand, thus squeezing and breaking the glass tube. At this time, the water in the water pipe will flow out for fire extinguishing.

[0003] In the prior art, the fire sprinkler controls the spraying of water source through a glass tube. Although it can spray water source for fire extinguishing when a fire occurs, since the glass tube is disposable, after it is broken and the fire sprinkler sprays out the water source, because it cannot be restored, the fire sprinkler will keep spraying water source until the water supply to the pipeline of the fire sprinkler is stopped to stop the spraying of the fire sprinkler. And when the fire sprinkler has completed fire extinguishing, because it will keep spraying water source, it is relatively wasteful of water source. Therefore, it needs to be improved. Content of the Utility Model

[0004] To solve the problems raised in the above background art, the utility model provides a suspended fire sprinkler, which has the advantage of stopping spraying after fire extinguishing.

[0005] To achieve the above object, the utility model provides the following technical solution: A suspended fire sprinkler includes a water pipe joint, and further includes a sprinkling hole which is opened inside the water pipe joint;

[0006] A water blocking mechanism which is fixedly connected inside the water pipe joint;

[0007] A control component which is arranged on the water pipe joint and the water blocking mechanism to cooperate with the water blocking mechanism to control the spraying of water source. The control component includes a cavity, a storage block and a through hole;

[0008] The water blocking mechanism includes a fixed block which is fixedly installed inside the water pipe joint. A communication hole communicating with the sprinkling hole is opened inside the fixed block. An activity cavity is opened inside the fixed block. A piston block which blocks the communication hole is slidably assembled inside the fixed block.

[0009] Preferably, the cavity is opened inside the water pipe joint. The storage block is fixedly installed outside the water pipe joint. The through hole is opened inside the water pipe joint and the storage block to communicate the cavity with the storage block.

[0010] Preferably, the control component further includes a slot hole and a piston rod. The slot hole is opened inside the fixed block and communicates with the cavity. The piston rod is fixedly connected to the left end of the piston block, and the other end of the piston rod extends into the slot hole.

[0011] Preferably, a bracket is fixedly connected to the bottom of the water pipe joint, a threaded rod is threadedly assembled inside the bracket, and a water baffle is fixedly connected to the bottom of the threaded rod.

[0012] Preferably, water sprinkling grooves are formed in the water baffle, and the water sprinkling grooves are uniformly distributed around the water baffle.

[0013] Preferably, a heat-sensitive glass tube is movably installed at the bottom of the water pipe joint, and the other end of the heat-sensitive glass tube is slidably connected to the threaded rod.

[0014] Preferably, the water pipe joint is made of ceramic, and the storage block is made of metal.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] The present utility model stores alcohol through the cavity and the storage block. When the alcohol expands due to heat, it can push the piston rod to make the piston block move, so that the communication hole is completely penetrated. Therefore, water can be ejected during a fire. When the fire source is extinguished, the temperature of the environment will decrease. Therefore, the alcohol will contract to reset the piston block to block the communication hole, so that the water source cannot be ejected, and water can be saved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] As Figures 1 to 5 shown, the present invention provides a suspended fire sprinkler, which includes a water pipe joint 1 and also includes a sprinkler hole 2 opened inside the water pipe joint 1;

[0025] a water blocking mechanism 3 fixedly connected inside the water pipe joint 1;

[0026] a control component 4 disposed on the water pipe joint 1 and the water blocking mechanism 3 for cooperating with the water blocking mechanism 3 to control the spraying of water source. The control component 4 includes a cavity 401, a storage block 402 and a through hole 403;

[0027] The water blocking mechanism 3 includes a fixed block 301 fixedly installed inside the water pipe joint 1. A communication hole 302 communicating with the sprinkler hole 2 is opened inside the fixed block 301. An activity cavity 303 is opened inside the fixed block 301. A piston block 304 that blocks the communication hole 302 is slidably assembled inside the fixed block 301.

[0028] With the above scheme, when the piston block 304 blocks the communication hole 302, the water source inside the water pipe joint 1 cannot be sprayed out from the sprinkler hole 2 through the communication hole 302. When the piston block 304 moves to the inside of the activity cavity 303 to the right, the communication hole 302 can be completely penetrated. Therefore, the water source inside the water pipe joint 1 can be sprayed out from the sprinkler hole 2 through the communication hole 302 for fire extinguishing.

[0029] As Figure 3 and Figure 5 shown, the cavity 401 is opened inside the water pipe joint 1. The storage block 402 is fixedly installed outside the water pipe joint 1. The through hole 403 is opened inside the water pipe joint 1 and the storage block 402 to communicate the cavity 401 with the storage block 402.

[0030] With the above scheme, alcohol is stored inside the cavity 401 and the storage block 402. The alcohol inside the cavity 401 and the storage block 402 can flow through the through hole 403. When the external temperature increases, the alcohol inside the cavity 401 and the storage block 402 will expand, thereby increasing the pressure.

[0031] As Figure 3As shown, the control component 4 further includes a slot hole 404 and a piston rod 405. The slot hole 404 is opened inside the fixed block 301 and communicates with the cavity 401. The piston rod 405 is fixedly connected to the left end of the piston block 304, and the other end of the piston rod 405 extends into the slot hole 404.

[0032] With the above solution, the inside of the slot hole 404 is also filled with alcohol. When the alcohol expands due to heat, it will push the piston rod 405, causing the piston block 304 to move to the right into the inside of the movable cavity 303, making the communication hole 302 completely penetrate. Therefore, the water source can spray out through the communication hole 302 from the sprinkler hole 2 to extinguish the fire.

[0033] As Figure 2 shown, a bracket 5 is fixedly connected to the bottom of the water pipe joint 1. A threaded rod 6 is threadedly assembled inside the bracket 5, and a water baffle 7 is fixedly connected to the bottom of the threaded rod 6.

[0034] With the above solution, the water baffle 7 can be installed below the bracket 5 through the threaded rod 6. At the same time, the threaded rod 6 can squeeze the heat-sensitive glass tube 8 to fix the heat-sensitive glass tube 8, preventing the heat-sensitive glass tube 8 from moving accidentally.

[0035] As Figure 1 shown, a sprinkler groove 701 is opened on the water baffle 7, and the sprinkler grooves 701 are evenly distributed around the water baffle 7.

[0036] With the above solution, through the design of the sprinkler groove 701, when the water flow impacts on the water baffle 7, it can be sprayed in more directions, thus increasing the range of the sprayed water source.

[0037] As Figure 2 shown, a heat-sensitive glass tube 8 is movably installed at the bottom of the water pipe joint 1, and the other end of the heat-sensitive glass tube 8 is slidably connected to the threaded rod 6.

[0038] With the above solution, when the threaded rod 6 rotates and contacts the heat-sensitive glass tube 8 and the other end of the heat-sensitive glass tube 8 contacts the water pipe joint 1, the rotation of the threaded rod 6 can squeeze the heat-sensitive glass tube 8, preventing the heat-sensitive glass tube 8 from moving accidentally. Therefore, the heat-sensitive glass tube 8 can be fixed.

[0039] As Figure 1 shown, the water pipe joint 1 is made of ceramic, and the storage block 402 is made of metal.

[0040] With the above solution, since the thermal conductivity of the ceramic is relatively low, the water pipe joint 1 can reduce the influence of the alcohol inside the cavity 401 after expansion by the low-temperature water source, preventing the piston block 304 from accidentally blocking the communication hole 302, and making it easier for the storage block 402 to heat the alcohol.

[0041] Working principle and usage process of the present utility model:

[0042] When the external environmental temperature is relatively high, the alcohol stored inside the cavity 401 and the storage block 402 will expand due to heat, and thus can push the piston rod 405 to make the piston block 304 move into the interior of the movable cavity 303. Therefore, the communication hole 302 will be completely penetrated. When the temperature is higher than the threshold value, the heat-sensitive glass tube 8 will break, enabling the water source to be sprayed out from the sprinkling hole 2 through the communication hole 302 for fire extinguishing.

[0043] Then, after the fire source is extinguished and the environmental temperature drops, the alcohol that has expanded due to heat will contract, thereby reducing the pressure and pulling the piston block 304 back to its original position through the piston rod 405, thus blocking the communication hole 302 and preventing the water source from spraying out from the sprinkling hole 2 through the communication hole 302.

[0044] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0045] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
