Description

Technical Field

[0001] The present invention relates to the technical field of sprinkler devices, and particularly relates to a fire sprinkler device. Background Art

[0002] A fire sprinkler head is a water spraying device used in an indoor fire protection system, usually installed on the ceiling. The sprinkler head can sense the heat around it. When a fire occurs and the ambient temperature rises to a set range, the alcohol in the glass container inside the sprinkler head expands due to heat until the glass breaks. After the seal loses support, it is washed away by the water flow, thereby starting to spray water to extinguish the fire at the fire location. However, current fire sprinkler heads are all disposable and need to be replaced after being triggered, resulting in relatively high maintenance costs and reducing practicality. Summary of the Invention

[0003] The main object of the present invention is to provide a fire sprinkler device to reduce maintenance costs and improve practicality.

[0004] To achieve the above object, the present invention provides a fire sprinkler device, including a protective frame. An outlet pipe is arranged inside the protective frame, and both sides of the outlet pipe extend to the outside of the protective frame. One side of the outlet pipe inside the protective frame is fixedly connected with a spherical frame, and a spherical sealing block is rotatably connected inside the spherical frame; An outlet channel is arranged inside the outlet pipe, and a circulation port is arranged inside the spherical sealing block. When the axes of the outlet channel and the circulation port coincide, the outlet pipe is in a water outlet state; when the axis of the outlet channel intersects the axis of the circulation port at 90 degrees, the outlet pipe is in a closed state; It further includes a triggering mechanism for rotating the spherical sealing block to make the axis of the circulation port on the spherical sealing block coincide with or intersect the axis of the outlet channel at 90 degrees.

[0005] In a possible implementation manner, the spherical sealing block is rotatably connected with the spherical frame through a rotating shaft. Both sides of the rotating shaft extend to the outside of the spherical frame and are fixedly connected with rotating frames. The two rotating frames form an angle of 45 degrees with the axis of the circulation port. On the opposite sides of the two rotating frames, arc-shaped gears are fixedly connected, and the center of the arc-shaped gear coincides with the center of the rotating shaft. The triggering mechanism includes a rack slidably connected inside the protective frame and a pushing component for pushing the rack to move downward or upward. The rack meshes with the arc-shaped gear.

[0006] In a possible implementation manner, a bottom plate is fixedly connected inside the protective frame. Guide rods are fixedly connected to the four corners of the bottom plate. At the top of the two guide rods, connecting plates are fixedly connected, and the gap between the two connecting plates is greater than the width of the rack. A sliding plate is fixedly connected to the bottom of the rack, and the sliding plate is slidably connected with each guide rod.

[0007] In a possible implementation manner, the pushing component includes a heat-conducting frame, a fixed cylinder, a piston, a telescopic rod, and a connecting rod. The heat-conducting frame is arranged inside the protection frame and extends to the outside of the protection frame on one side. The protection frame is filled with a thermally expandable gas. The fixed cylinder is arranged inside the protection frame and on the side away from the rack. The piston is slidably connected to the inside of the fixed cylinder. The telescopic rod is arranged on the side of the piston away from the bottom of the fixed cylinder and is fixedly connected to the piston. The heat-conducting frame is communicated with the bottom of the fixed cylinder through an air delivery pipe. An extension plate is fixedly connected to the top of the connecting plate. The connecting rod is rotatably connected to the extension plate through a rotating shaft. One end of the connecting rod is connected to the telescopic rod, and the other end of the connecting rod is connected to the rack.

[0008] In a possible implementation manner, first sliding grooves and second sliding grooves are respectively arranged on both sides of the connecting rod. A first roller is arranged on the side of the telescopic rod close to the connecting rod, and the first roller is rotatably connected to the telescopic rod. The first roller is slidably connected to the inner wall of the first sliding groove. A second roller is arranged on the side of the rack close to the connecting rod, and the second roller is rotatably connected to the rack. The second roller is slidably connected to the inner wall of the second sliding groove.

[0009] In a possible implementation manner, the distance from the telescopic rod to the rotating shaft is greater than the distance from the rack to the rotating shaft. A first elastic member is arranged between the sliding plate and the bottom plate. One end of the first elastic member is fixedly connected to the sliding plate, and the other end of the first elastic member is fixedly connected to the bottom plate.

[0010] In a possible implementation manner, a fixing mechanism for fixing the rack is further arranged at the bottom of the protection frame. The fixing mechanism includes a receiving block, a second elastic member, and a fixing block. The receiving block is fixedly connected to the inside of the protection frame through a plurality of support frames. A receiving groove is arranged on the side of the receiving block close to the first elastic member. One side of the fixing block is arranged inside the receiving groove and is slidably connected to the inner wall of the receiving groove. One side of the second elastic member abuts against the side surface of the receiving groove, and the other side of the second elastic member abuts against the side surface of the fixing block. A first inclined surface is arranged on the side of the fixing block away from the bottom plate. A second inclined surface that is slidably connected to the first inclined surface is arranged on the side of the sliding plate close to the fixing block.

[0011] In a possible implementation manner, a traction component for retracting the fixing block into the receiving groove is arranged at the bottom of the protection frame. The traction component includes a traction rope, a roller, and a winding shaft. The winding shaft is rotatably connected to the bottom of the protection frame, and one side of the winding shaft extends to the outside of the protection frame. The roller is fixedly connected to the side of the winding shaft away from the protection frame. One end of the traction rope is fixedly connected to the side of the fixing block close to the second elastic member, and the other end of the traction rope is fixedly connected to the winding shaft through a plurality of pulleys.

When a dangerous situation occurs, the trigger mechanism drives the spherical sealing block to rotate, so that the flow port on it coincides with the axis of the water outlet channel, so that water flows out from the water outlet pipe to extinguish the fire. After the fire is extinguished, the trigger mechanism drives the spherical sealing block to rotate, so that the axis of the flow port intersects the axis of the water outlet channel at 90 degrees, thereby closing the water outlet pipe. Compared with the traditional disposable fire sprinkler head, this sprinkler device can be reused, reducing the maintenance cost and significantly improving its practicability.

[0016] The realization, functional features and advantages of the purpose of the present invention will be further described with reference to the embodiments and the accompanying drawings. Detailed implementation manners

[0017] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application. Embodiment

[0018] Refer to Figures 1-5 , the present invention provides a fire sprinkler device, including a protection frame 1. A water outlet pipe 101 is arranged inside the protection frame 1, and both sides of the water outlet pipe 101 extend to the outside of the protection frame 1. One side of the water outlet pipe 101 inside the protection frame 1 is fixedly connected with a spherical frame 102, and a spherical sealing block 103 is rotatably connected inside the spherical frame 102; A water outlet channel 104 is arranged inside the water outlet pipe 101, and a circulation port 105 (the circulation port 105 is a through hole penetrating the spherical sealing block 103) is arranged inside the spherical sealing block 103. When the axes of the water outlet channel 104 and the circulation port 105 coincide, the water outlet pipe 101 is in a water outlet state; when the axis of the water outlet channel 104 intersects the axis of the circulation port 105 at 90 degrees, the water outlet pipe 101 is in a closed state; It further includes a triggering mechanism for rotating the spherical sealing block 103 to make the axis of the circulation port 105 on the spherical sealing block 103 coincide with or intersect the axis of the water outlet channel 104 at 90 degrees.

[0019] By arranging a water outlet pipe 101, a spherical frame 102, a spherical sealing block 103 and a triggering mechanism inside a protection frame 1, a fire sprinkler device capable of flexibly controlling the on-off of water flow is constructed. When a dangerous situation occurs, the triggering mechanism drives the spherical sealing block 103 to rotate, making the through hole 105 on it coincide with the axis of the water outlet channel 104, so that water flows out from the water outlet pipe 101 to extinguish the fire. After the fire is extinguished, the triggering mechanism drives the spherical sealing block 103 to rotate, making the axis of the through hole 105 intersect with the axis of the water outlet channel 104 at 90 degrees, thus closing the water outlet pipe 101. Compared with traditional disposable fire sprinkler heads, this sprinkler device can be reused, reducing the maintenance cost and significantly improving its practicability.

[0020] Furthermore, the spherical sealing block 103 is rotatably connected to the spherical frame 102 through a rotating shaft 106. Both sides of the rotating shaft 106 extend outside the spherical frame 102 and are fixedly connected with rotating frames 107. The two rotating frames 107 form an angle of 45 degrees with the axis of the through hole 105. On the opposite sides of the two rotating frames 107, there is fixedly connected an arc-shaped gear 108 (as can be seen from the attached Figure 4 , it has only one section), and the center of the arc-shaped gear 108 coincides with the center of the rotating shaft 106. The triggering mechanism includes a rack 2 that is slidably connected to the inside of the protection frame 1 and a pushing component for pushing the rack 2 to move downward or upward. The rack 2 meshes with the arc-shaped gear 108 to enable the arc-shaped gear 108 to rotate counterclockwise by 90 degrees.

[0021] When the triggering mechanism acts, the pushing component pushes the rack 2 to move downward. The rack 2 drives the arc-shaped gear 108 to rotate counterclockwise. At the same time, the arc-shaped gear 108 drives the rotating frame 107 and the rotating shaft 106 to rotate counterclockwise. Furthermore, the rotating shaft 106 drives the spherical sealing block 103 to rotate counterclockwise by 90 degrees. Finally, the through hole 105 on the spherical sealing block 103 coincides with the axis of the water outlet channel 104, and then water flows out from the water outlet pipe 101 to extinguish the fire. This embodiment utilizes the transmission between the arc-shaped gear 1058 and the rack 2, which has high transmission accuracy and strong stability, can accurately control the rotation angle of the spherical sealing block 103, and ensure that the water flow of the sprinkler head can be timely opened or closed when needed, thereby improving the reliability and response speed of the fire sprinkler device.

[0022] Furthermore, a bottom plate 201 is fixedly connected inside the protection frame 1. Guide rods 202 are fixedly connected to the four corners of the bottom plate 201. At the top of the two guide rods 202, there is fixedly connected a connecting plate 203, and the gap between the two connecting plates 203 is greater than the width of the rack 2. The bottom of the rack 2 is fixedly connected with a sliding plate 204, which is slidably connected to each guide rod 202.

[0023] A bottom plate 201, guide rods 202 and connecting plates 203 are arranged inside the protection frame 1. The rack 2 is slidably connected to the guide rods 202 through a sliding plate 204 at the bottom. This design provides a stable guiding effect for the movement of the rack 2, enabling the rack 2 to maintain linear motion during the up and down movement, and avoiding the occurrence of poor meshing with the arc gear 108 due to offset. At the same time, the gap design between the connecting plates 203 ensures that the rack 2 and the arc gear 108 can move smoothly therein, further improving the stability and reliability of the entire transmission system.

[0024] Specifically, the pushing component includes a heat-conducting frame 205, a fixed cylinder 206, a piston 207, a telescopic rod 208, and a connecting rod 209. The heat-conducting frame 205 is arranged inside the protection frame 1 and extends to the outside of the protection frame 1 on one side. The inside of the protection frame 1 is filled with a thermally expandable gas. The fixed cylinder 206 is arranged inside the protection frame 1 and on the side away from the rack 2. The piston 207 is slidably connected to the inside of the fixed cylinder 206. The telescopic rod 208 is arranged on the side of the piston 207 away from the bottom of the fixed cylinder 206 and is fixedly connected to the piston 207. The heat-conducting frame 205 is communicated with the bottom of the fixed cylinder 206 through an air pipe 210. A extending plate 215 is fixedly connected to the top of the connecting plate 203. The connecting rod 209 is rotatably connected to the extending plate 215 through a rotating shaft 216. One end of the connecting rod 209 is connected to the telescopic rod 208, and the other end of the connecting rod 209 is connected to the rack 2.

[0025] Secondly, a first sliding groove 211 and a second sliding groove 212 are respectively arranged on both sides of the connecting rod 209. A first roller 213 is arranged on the side of the telescopic rod 208 close to the connecting rod 209, and the first roller 213 is rotatably connected to the telescopic rod 208. The first roller 213 is slidably connected to the inner wall of the first sliding groove 211. A second roller 214 is arranged on the side of the rack 2 close to the connecting rod 209, and the second roller 214 is rotatably connected to the rack 2. The second roller 214 is slidably connected to the inner wall of the second sliding groove 212.

[0026] When a fire breaks out and the ambient temperature rises, the heat-conducting frame 205 senses the heat, causing the thermal expansion gas in the protection frame 1 to expand due to heat, increasing the pressure. The gas enters the bottom of the fixed cylinder 206 through the air delivery pipe 210, pushing the piston 207 in the fixed cylinder 206 to move, and then driving the telescopic rod 208 to extend. When the telescopic rod 208 moves upward under the action of air pressure, the first roller 213 on the telescopic rod 208 will roll in the first sliding groove 211, causing the connecting rod 209 to rotate around the rotating shaft 216. The other end of the connecting rod 209 pushes the rack 2 to move downward along the guide rod 202, and the second roller 214 on the side of the rack 2 makes an adaptive roll in the second sliding groove. At the same time, the rack 2 drives the arc-shaped gear 108 to rotate counterclockwise, and then the rotating shaft 106 drives the spherical seal block 103 to rotate counterclockwise by 90 degrees. Finally, the flow port 105 on the spherical seal block 103 coincides with the axis of the water outlet channel 104, and water flows out from the water outlet pipe 101 to extinguish the fire.

[0027] In this embodiment, the pushing component uses an automatic trigger design based on the principle of thermal expansion, which does not require manual operation and can quickly respond in the initial stage of a fire, spraying water in time to extinguish the fire, thus greatly improving the timeliness and automation level of the fire sprinkler device in dealing with fires.

[0028] It should be noted that since the movement of the connecting rod 209 is a rotational movement, if the rotational movement of the connecting rod 209 is to be converted into the linear movement of the rack 2 and the telescopic rod 208, an additional connecting rod must be added between the two, and both sides of this connecting rod are respectively rotationally connected to the connecting rod 209 and the telescopic rod 208. At the same time, a connecting rod is also arranged between the other side of the connecting rod 209 and the rack 2 to realize the conversion of the rotational movement of the connecting rod 209 into the linear movement of the rack 2 and the telescopic rod 208. However, adding an additional connecting rod will make the overall structure of the pushing component too compact and complex, and increase the installation and manufacturing costs. For this reason, in this embodiment, the first sliding groove 211 and the second sliding groove 212 are directly opened on the connecting rod 209, and the first roller 213 and the second roller 214 are arranged at the corresponding positions of the telescopic rod 208 and the rack 2, so as to convert the rotational movement of the connecting rod 209 into the linear movement of the rack 2 and the telescopic rod 208, thereby reducing the manufacturing cost and installation difficulty.

[0029] The first roller 213 and the second roller 214 are respectively rotationally connected to the side of the telescopic rod 208 and the rack 2, so that when the telescopic rod 208 moves upward, the first roller 213 can roll in the first sliding groove 211, and the second roller 214 can roll in the second sliding groove 212, significantly reducing the friction force (because the friction force received by dynamic friction is smaller than that of static friction), thereby improving the transmission efficiency and avoiding jamming of the first roller 213 and the second roller 214 in the sliding groove, further improving the reliability and stability of the pushing component during long-term use.

[0030] Further, the distance from the telescopic rod 208 to the rotating shaft 216 is greater than the distance from the rack 2 to the rotating shaft 216. A first elastic member 217 is provided between the sliding plate 204 and the bottom plate 201. One end of the first elastic member 217 is fixedly connected to the sliding plate 204, and the other end of the first elastic member 217 is fixedly connected to the bottom plate 201. The distance from the telescopic rod 208 to the rotating shaft 216 being greater than the distance from the rack 2 to the rotating shaft 216 forms a force amplification structure, enabling a smaller displacement of the telescopic rod 208 to be converted into a larger displacement of the rack 2, and more efficiently pushing the rack 2 to move to achieve the rotation of the spherical seal block 103. At the same time, after the pressure of the thermally expanded gas disappears, the first elastic member 217 between the sliding plate 204 and the bottom plate 201 can automatically reset the rack 2 and close the spraying device.

[0031] At the same time, such a design makes the connecting rod 209 become a labor-saving lever, and the specific principle is as follows: The distance between the telescopic rod 208 and the rotating shaft 216 is the power arm, and the distance between the rack 2 and the rotating shaft 216 is the resistance arm. When the power arm is greater than the resistance arm, the telescopic rod 208 only needs to apply a smaller force to drive the rack 2 to move downward, and at the same time drive the arc gear 108 to rotate, so that the spherical seal block 103 can obtain a greater force, sufficient to overcome the pressure of the water flow in the water outlet pipe 101 and rotate smoothly, thereby quickly opening the spraying device, spraying water in time to extinguish the fire, and effectively improving the response speed and fire extinguishing efficiency of the device in the initial stage of the fire.

[0032] The application of the labor-saving lever reduces the excessive requirement for the pressure of the thermally expanded gas. Even if the pressure generated by the thermally expanded gas is low due to various reasons, the labor-saving effect of the lever can still be relied on to ensure that the spherical seal block 103 obtains sufficient power to overcome the water pressure and rotate, ensuring the normal operation of the spraying device and improving the stability and reliability of the entire fire sprinkler device.

[0033] In this embodiment, a push rod 2041 is also fixedly connected to the bottom of the sliding plate 204. The first elastic member 217 is sleeved on the outer surface of the push rod 2041. One side of the push rod 2041 away from the sliding plate 204 penetrates through the bottom of the protective frame 1 and extends to the outside of the protective frame 1. A push plate 2042 is fixedly connected to the side of the push rod 2041 away from the protective frame 1.

[0034] A push rod 2041 is fixedly connected to the bottom of the sliding plate 204, and a push plate 2042 is arranged at the end of the push rod 2041, providing a manual emergency operation mode for the fire sprinkler device. When a fire breaks out indoors and the residents cannot find a water source, the residents can pull out the push plate 2042 from the protective frame 1. The push plate 2042 drives the sliding plate 204 to move downward through the push rod 2041, and then drives the rack 2 to move downward. The rack 2 drives the arc gear 108 to rotate counterclockwise by 90 degrees, so that the flow port 105 on the spherical seal block 103 coincides with the axis of the water outlet channel 104, so that water flows out from the water outlet pipe 101. After the fire is extinguished, the residents can push the push plate 2042 and the push rod 2041 back into the protective frame 1, or wait for the first elastic member 217 to restore its deformation. This design enhances the reliability and adaptability of the fire sprinkler device in various situations, ensures effective fire extinguishing in case of emergencies, and protects the safety of personnel and property.

[0035] Working principle: When a fire occurs and the ambient temperature rises, the heat-conducting frame 205 senses the heat, causing the thermal expansion gas in the protective frame 1 to expand due to heat, increasing the pressure. The gas enters the bottom of the fixed cylinder 206 through the air delivery pipe 210, pushing the piston 207 in the fixed cylinder 206 to move, and then driving the telescopic rod 208 to extend. When the telescopic rod 208 moves upward under the action of air pressure, the first roller 213 on the telescopic rod 208 will roll in the first sliding groove 211, causing the connecting rod 209 to rotate around the rotating shaft 216. The other end of the connecting rod 209 pushes the rack 2 to move downward along the guide rod 202 and compresses the first elastic member 217. The second roller 214 on the side of the rack 2 makes an adaptive roll in the second sliding groove. At the same time, the rack 2 drives the arc gear 108 to rotate counterclockwise, and then the rotating shaft 106 drives the spherical seal block 103 to rotate counterclockwise by 90 degrees. Finally, the flow port 105 on the spherical seal block 103 coincides with the axis of the water outlet channel 104, and water sprays out from the water outlet pipe 101 to extinguish the fire.

[0036] At the same time, when the rack 2 moves downward, the second inclined surface 305 on the sliding plate 204 pushes the fixed block 302 to retract into the receiving groove 303. After reaching the position, the fixed block 302 pops out under the action of the second elastic member 301 to block the sliding plate 204, keeping the spherical seal block 103 in the open state, ensuring continuous and stable water spraying before the fire is extinguished.

[0037] When the fire is extinguished, the air pressure inside the heat conducting frame 205 will drop. At this time, the first elastic member 217 will restore its deformation, pushing the sliding plate 204 and the rack 2 to move upward. Then, the rack 2 drives the arc gear 108 to rotate clockwise, and the arc gear 108 drives the rotating frame 107, the rotating shaft 106 and the spherical sealing block 103 to rotate 90 degrees clockwise, so that the flow port 105 on the spherical sealing block 103 intersects the axis of the water outlet channel 104 at 90 degrees, and finally closes the inside of the water outlet pipe 101. Example

[0038] Based on Example 1, refer to Figures 6-8 In this embodiment, a fixing mechanism is further provided at the bottom of the protective frame 1 for fixing the rack 2. The fixing mechanism includes a accommodating block 3, a second elastic member 301, and a fixed block 302. The accommodating block 3 is fixedly connected to the inside of the protective frame 1 through a number of support frames. A accommodating groove 303 is provided on the side of the accommodating block 3 close to the first elastic member 217. One side of the fixed block 302 is arranged inside the accommodating groove 303 and is slidably connected to the inner wall of the accommodating groove 303. One side of the second elastic member 301 abuts against the side of the accommodating groove 303, and the other side of the second elastic member 301 abuts against the side of the fixed block 302. A first inclined surface 304 is provided on the side of the fixed block 302 away from the bottom plate 201, and a second inclined surface 305 slidably connected to the first inclined surface 304 is provided on the side of the sliding plate 204 close to the fixed block 302.

[0039] When the rack 2 moves downward, the second inclined surface 305 on the sliding plate 204 pushes the fixed block 302 to retract into the accommodating groove 303. After it is in place, the fixed block 302 pops out and clamps the sliding plate 204 under the action of the second elastic member 301, so that the spherical sealing block 103 remains in the open state, ensuring continuous and stable water spraying before the fire is extinguished, enhancing the fire extinguishing effect, and avoiding the shutdown of the sprinkler device due to the reduction of air pressure inside the heat conducting frame 205.

[0040] Furthermore, a traction assembly is provided at the bottom of the protective frame 1 to retract the fixed block 302 into the accommodating groove 303. The traction assembly includes a traction rope 4, a roller 401, and a winding shaft 402. The winding shaft 402 is rotatably connected to the bottom of the protective frame 1, and one side of the winding shaft 402 extends to the outside of the protective frame 1. The roller 401 is fixedly connected to the side of the winding shaft 402 away from the protective frame 1. One end of the traction rope 4 is fixedly connected to the side of the fixed block 302 close to the second elastic member 301, and the other end of the traction rope 4 is fixedly connected to the winding shaft 402 through a number of pulleys 403.

[0041] After the fire is extinguished, the staff can rotate the winding shaft 402 to use the towing rope 4 to pull the fixing block 302 to retract into the accommodating groove 303, releasing the fixation of the rack 2. At the same time, the first elastic member 217 will recover its deformation and push the sliding plate 204 and the rack 2 upward.
