Description

Technical Field

[0001] The present application belongs to the field of fire sprinklers, and more specifically, to a sprinkler head with a fast-trigger temperature-sensing component. Background Art

[0002] Traditional fire sprinklers have long played an important role in the field of fire safety, but with the passage of time and the advancement of technology, their defects have become increasingly prominent. First of all, the response speed of traditional fire sprinklers is slow, and they often cannot respond quickly in the early stages of a fire, which may lead to the fire not being controlled in time in the early stages, and thus causing greater losses. In addition, traditional fire sprinklers have limitations in environmental adaptability. The causes and characteristics of fires may vary in different places and environments. However, traditional fire sprinklers can often only trigger the water spraying action according to the preset temperature threshold, and cannot be flexibly adjusted according to the specific circumstances of the fire. This may cause the sprinkler to be triggered too late in some cases, or it may not be actively and quickly triggered in front of the path of fire spread to produce an early blocking effect, thereby failing to play the best fire extinguishing role; therefore, it is necessary to solve the above technical problems. Summary of the invention

[0003] The purpose of the embodiments of the present application is to provide a sprinkler head with a fast-trigger temperature sensing component to solve the technical problem of poor fire extinguishing effect of fire sprinklers in the prior art.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the present application is: to provide a sprinkler head with a fast-trigger temperature sensing component, comprising:

[0005] A frame, forming a water outlet;

[0006] A support assembly, comprising a tightening bolt threadedly connected to the frame and having a tip facing the water outlet, an inclined rod abutting against the tip of the tightening bolt, a vertical rod abutting against the side of the inclined rod away from the tightening bolt, and a stopper abutting against the vertical rod and used to block the water outlet, wherein the tip of the tightening bolt faces the water outlet;

[0007] The temperature sensing component includes two temperature sensing sheets bonded by fusible alloy and respectively clamped to the inclined rod and the vertical rod, the temperature sensing sheet has a first plate body and a second plate body formed by a depression from the middle area of ​​the first plate body, the second plate body is parallel to the first plate body, the two temperature sensing sheets abut against each other through their respective first plates and cooperate through the second plates to form a cavity, and the temperature sensing component also includes an electric heating sheet accommodated in the cavity and connected to the two temperature sensing sheets.

[0008] Optionally, a clamping hole is provided on the first plate body, and a reverse bend and a clamping portion for clamping the clamping hole are respectively provided on the sides of the oblique rod and the vertical rod that are opposite to each other, and the vertical rod is used to abut one end of the oblique rod to deviate from the reverse bend toward the center line of the tightening bolt and the water outlet.

[0009] Optionally, the first plate body is further provided with an opening groove corresponding to the clamping hole and capable of allowing the oblique rod and the vertical rod to be separated;

[0010] The opening grooves and the clamping holes are distributed on the first plate body at both sides of the second plate body, and the two temperature sensing sheets are attached to each other through the first plate body so that the opening grooves and the clamping holes are stacked.

[0011] Optionally, the first plate body is further provided with a circular hole and an arc-shaped protrusion capable of partially extending into the circular hole;

[0012] The circular holes and the arc-shaped protrusions are distributed on the first plate body at both sides of the second plate body, and the two temperature sensing sheets are attached through the first plate body so that the circular holes correspond to the arc-shaped protrusions.

[0013] Optionally, the first plate body is provided with a raised portion located at a same side of the first plate body at a corner of the opening groove, and the first plate body is formed with a folded edge at one end of the clamping hole.

[0014] Optionally, a plurality of notches are arranged at intervals on the edge of the electric heating plate, and the electric heating plate has an electric heating wire and is insulated from the temperature sensing plate.

[0015] Optionally, the temperature sensing piece is made of nickel alloy.

[0016] Optionally, the stopper and the diagonal rod are respectively provided with grooves for abutting against the vertical rod.

[0017] Optionally, a sealing gasket is provided between the stop head and the frame.

[0018] Optionally, the sprinkler head with a fast-trigger temperature-sensing component further includes a splash plate connected to the frame, wherein the splash plate is perpendicular to a center line connecting the tightening bolt and the water outlet.

[0019] The beneficial effect of the sprinkler head with a fast-trigger temperature-sensing component provided by the present application is that: compared with the prior art, the sprinkler head provided by the present application is provided with a double-trigger temperature-sensing component, wherein the temperature-sensing component includes two temperature-sensing sheets bonded by fusible alloy and respectively clamped to the inclined rod and the vertical rod. On the one hand, the two temperature-sensing sheets can be separated when the fire causes their own temperature to passively rise to the melting threshold of the fusible alloy; on the other hand, since the two temperature-sensing sheets cooperate with their respective first plate bodies and second plate bodies to form a cavity accommodating the electric heating sheet, the two temperature-sensing sheets can reach the melting temperature threshold of the fusible alloy and separate during the active heating process of the electric heating sheet. When the two temperature-sensing sheets are separated, the supporting structure formed by the tightening bolts, the diagonal rods, the vertical rods and the stopper can quickly collapse and separate the stopper from the water outlet, thereby realizing the rapid opening of the water outlet, significantly shortening the response time of the sprinkler head with a fast-trigger temperature-sensing component in the present application to a fire, while also being conducive to effectively improving its flexibility. The active start-up of the sprinkler head can also be controlled by the control system through the dynamic heating effect of the electric heating sheet, which has a good fire-extinguishing effect. In addition, the electric heating sheet is arranged between the temperature-sensing sheets. On the one hand, the outer surface of the temperature-sensing sheet can be directly in contact with the environment without obstruction, so that the ambient temperature can be better sensed and the heat can be transferred to the fusible alloy to ensure the triggering sensitivity of the temperature-sensing component to the occurrence of a fire. On the other hand, when the electric heating sheet is used to actively trigger the temperature-sensing component, the heat generated by the electric heating sheet can be simultaneously transferred to the temperature-sensing sheet from both sides, thereby making it easier and faster for the fusible alloy to reach the melting threshold. The thermal efficiency of the electric heating sheet is more fully utilized, and the triggering response speed is faster, which is far superior to the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Please also read Figures 1 to 4 Now, a sprinkler head with a fast-trigger temperature sensing component provided in an embodiment of the present application is described. The sprinkler head with a fast-trigger temperature sensing component includes a frame 101, a support component and a temperature sensing component. Among them:

[0031] The frame 101 forms a water outlet 102, and it is understood that the water outlet 102 is also connected to a fire-fighting pipe for water discharge. The support assembly includes a jacking bolt 103 threadedly connected to the frame 101 and with its tip facing the water outlet 102, an inclined rod 104 abutting against the tip of the jacking bolt 103, a vertical rod 105 abutting against the side of the inclined rod 104 away from the jacking bolt 103, and a stopper 106 abutting against the vertical rod 105 and used to block the water outlet 102, and the tip of the jacking bolt 103 faces the water outlet 102. The temperature sensing component includes two temperature sensing pieces 107 bonded by fusible alloy and respectively clamped to the diagonal rod 104 and the vertical rod 105. The temperature sensing piece 107 has a first plate body 171 and a second plate body 172 formed by a depression from the middle area of ​​the first plate body 171. The second plate body 172 is parallel to the first plate body 171. The two temperature sensing pieces 107 abut against each other through their respective first plates 171 and cooperate through the second plates 172 to form a cavity 173. The temperature sensing component also includes an electric heating piece 108 accommodated in the cavity 173 and connected to the two temperature sensing pieces 107. Here, when on fire duty, the electric heating piece 108 is electrically connected to the fire control system.

[0032] According to the above structure provided in this embodiment, the temperature sensing component includes two temperature sensing pieces 107 bonded by fusible alloy and respectively clamped to the diagonal rod 104 and the vertical rod 105. On the one hand, the two temperature sensing pieces 107 can be separated when the temperature of the two temperature sensing pieces 107 is passively raised to a threshold value due to a fire; on the other hand, since the two temperature sensing pieces 107 cooperate with each other through the first plate 171 and the second plate 172 to form a cavity 173 containing the electric heating piece 108, the two temperature sensing pieces 107 can reach the temperature threshold and separate during the active heating process of the electric heating piece 108. Since one end of the vertical rod 105 used to abut against the inclined rod 104 deviates from the center line between the tightening bolt 103 and the water outlet 102, when the two temperature sensing sheets 107 are separated, the support structure formed by the tightening bolt 103, the inclined rod 104, the vertical rod 105 and the stopper 106 can quickly collapse and make the stopper 106 separate from the water outlet 102, thereby realizing the rapid opening of the water outlet 102, which significantly shortens the response time of the sprinkler head with a fast-trigger temperature sensing component in this embodiment to a fire, and is also conducive to effectively improving its flexibility, and the control system can also control the sprinkler head through the dynamic heating effect of the electric heating sheet. The active start-up of the water sprinkler has a good fire extinguishing effect. In addition, the electric heating plate is arranged between the temperature-sensitive plates. On the one hand, the outer surface of the temperature-sensitive plate can be directly in contact with the environment without obstruction, so that the ambient temperature can be better sensed and the heat can be transferred to the fusible alloy to ensure the triggering sensitivity of the temperature-sensitive component when a fire occurs. On the other hand, when the electric heating plate is used to actively trigger the temperature-sensitive component, the heat generated by the electric heating plate can be transferred to the temperature-sensitive plate from both sides at the same time, thereby making it easier and faster for the fusible alloy to reach the melting threshold. The thermal efficiency of the electric heating plate is more fully utilized, and the triggering response speed is faster, which is far superior to the existing technology.

[0033] In another embodiment of the present application, please refer to Figures 1 to 4 The first plate 171 is provided with a clamping hole 174, and the sides of the inclined rod 104 and the vertical rod 105 that are away from each other are respectively provided with a reverse bend 182 and a clamping portion 109 for clamping the clamping hole 174, and one end of the vertical rod 105 that is used to abut the inclined rod 104 deviates from the central line between the jacking bolt 103 and the water outlet 102 toward the reverse bend 182. According to the above structure provided in this embodiment, the two temperature sensing plates 107 can be stably clamped on the inclined rod 104 and the vertical rod 105 through their respective clamping holes 174, which is conducive to enabling the sprinkler provided in this embodiment to be in a stable fire duty state for a longer period of time and have a better fire extinguishing effect.

[0034] In another embodiment of the present application, please refer to Figures 1 to 4 The first plate 171 is also provided with an opening groove 175 corresponding to the snap-in hole 174 and capable of separating the inclined rod 104 and the vertical rod 105. The opening groove 175 and the snap-in hole 174 are distributed on the first plate 171 on both sides of the second plate 172. The two temperature sensing pieces 107 are attached to the first plate 171 so that the opening groove 175 and the snap-in hole 174 are stacked. According to the above structure provided in this embodiment, by providing the opening groove 175 corresponding to the snap-in hole 174 on the first plate 171, on the one hand, the two temperature sensing pieces 107 can be quickly separated, and on the other hand, the contact area after the first plate 171 is attached to each other can be increased, so that the two temperature sensing pieces 107 have better installation stability after being bonded by the fusible alloy, which is conducive to the sprinkler head provided in this embodiment being in a stable fire duty state for a longer time and having a better fire extinguishing effect.

[0035] In another embodiment of the present application, please refer to Figures 1 to 4 The first plate 171 is also provided with a circular hole 176 and an arc-shaped protrusion 177 that can partially extend into the circular hole 176. The circular hole 176 and the arc-shaped protrusion 177 are distributed on the first plate 171 on both sides of the second plate 172. The two temperature sensing pieces 107 are fitted through the first plate 171 so that the circular hole 176 corresponds to the arc-shaped protrusion 177. According to the above structure provided in this embodiment, when the fusible alloy between the two temperature sensing pieces 107 melts, under the drive of the inclined rod 104 and the vertical rod 105, the first plate 171 can slide on the surface of the arc-shaped protrusion 177 through the matching structure of the circular hole 176 and the arc-shaped protrusion 177, thereby quickly separating the first plate 171 from the second plate 172, which is conducive to further shortening the response time of the sprinkler head provided in this embodiment to the fire and having a better fire extinguishing effect.

[0036] In another embodiment of the present application, please refer to Figures 1 to 4 , the first plate 171 is provided with a tilting portion 178 located on the same side of the first plate 171 at the corner of the opening groove 175, and the first plate 171 is formed with a folding edge 183 at one end of the clamping hole 174. According to the above structure provided in this embodiment, the tilting portion 178 and the folding edge 183 provided on the first plate 171 can, on the one hand, improve the structural strength of the temperature sensing piece 107 to achieve a high-stability fire duty effect; on the other hand, it can also facilitate the gripping of the temperature sensing piece 107, which is conducive to the sprinkler head provided in this embodiment being installed more quickly. In addition, setting the tilting portion 178 to be located on the same side of the first plate 171 is conducive to making the two temperature sensing pieces 107 fit together more closely, which is conducive to making the sprinkler head provided in this embodiment be in a stable fire duty state for a longer period of time, and having a better fire extinguishing effect.
