[0002] Because the nozzles of a rotary sprinkler system can rotate, the rotation of the nozzles not only enables uniform spraying of the medium, but also expands the coverage area of ​​the medium. Furthermore, the centrifugal force generated during the rotation process further ensures uniform spraying of the medium. Therefore, rotary sprinkler systems have become an important piece of equipment for fire protection and emergency fire suppression in large spaces.

[0003] However, the existing rotary sprinkler system has a relatively complex structure. For example, the Chinese utility model patent CN218357031U previously filed by the applicant, "An Automatic Sprinkler System for Indoor Fire Fighting," involves a rotary sprinkler device that includes an outer cylinder and a water outlet mechanism. The water outlet mechanism includes a reduction gear set, a water inlet impeller assembly, a rotating inner pipe assembly, a connecting outer pipe assembly, and a bearing assembly. Each of these components includes multiple parts, making the overall structure of the rotary sprinkler device complex.

Detailed Implementation

[0035] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0036] Example 1

[0037] like Figures 1 to 5As shown, this utility model provides a rotary water spray mechanism, including a mounting cylinder 11. The mounting cylinder 11 includes a side wall 111 and a first end plate 112 and a second end plate 113 respectively disposed at both ends of the side wall 111. A water inlet 114 is provided in the first end plate 112. Specifically, a mounting pipe 115 is fixedly connected to the water inlet 114. The outer side wall of the mounting pipe 115 is provided with external threads to facilitate the connection of the rotary water spray mechanism with an external water supply mechanism. A fixing member is provided inside the mounting cylinder 11, and a rotating impeller 13 is rotatably disposed on the fixing member. The rotating impeller 13 has multiple blades 131 spaced apart. A water outlet channel 132 is provided between adjacent blades 131. A water inlet hole 133 is provided in the middle of the rotating impeller 13, which is connected to the multiple water outlet channels 132. The water inlet hole 133 is connected to the water inlet 114. A nozzle assembly 14 is connected to the rotating impeller 13. The nozzle assembly 14 is connected to the interior of the mounting cylinder 11. The nozzle assembly 14 can rotate synchronously with the rotating impeller 13. The end of the nozzle assembly 14 away from the rotating impeller 13 passes through the second end plate 113 and extends to the outside of the mounting cylinder 11. A multiple water outlet holes 141 are provided at the end of the nozzle assembly 14 away from the rotating impeller 13.

[0038] In actual use, the water supply is connected to an external water supply mechanism through the installation pipe 115. The water supplied by the water supply mechanism flows into the rotating impeller 13 through the inlet 114 and the inlet hole 133, and flows out through the outlet channel 132 to the interior of the installation cylinder 11. The water then flows into the nozzle assembly 14 and is sprayed to the outside through the outlet hole 141. As the water flows through the rotating impeller 13, the water will generate a thrust on the blades 131, causing the rotating impeller 13 to rotate. At the same time, the nozzle assembly 14 rotates synchronously with the rotating impeller 13, so that the nozzle assembly 14 can spray water outward while rotating.

[0039] The rotary water spray mechanism in this embodiment has a simple structure compared to the prior art, which helps to improve production efficiency, reduce production costs, and effectively reduce the failure rate.

[0040] Furthermore, such as Figure 2-3As shown in Figure 5, the interior of the mounting cylinder 11 is further provided with a water inlet cylinder 15. The water inlet cylinder 15 is connected to the first end plate 112 and inserted into the water inlet hole 133. The end of the water inlet cylinder 15 connected to the first end plate 112 has a water inlet 151, which is positioned directly opposite the water inlet 114. The cylinder wall 152 of the water inlet cylinder 15 has several drain holes 153. Specifically, the end of the water inlet cylinder 15 near the first end plate 112 has a connecting flange with several threaded connecting holes. The first end plate 112 also has several connecting holes corresponding to the threaded connecting holes. Several threaded connectors 17 pass through the connecting holes and threaded connecting holes in sequence to achieve a detachable connection between the water inlet cylinder 15 and the first end plate 112. In this embodiment, since the central axes of the inlet 151 and the outlet 153 of the inlet cylinder 15 are perpendicular to each other, the direction of water flow is changed by setting the inlet cylinder 15. The inlet cylinder 15 is inserted into the inlet hole 133 so that the outlet 153 is directly facing the blade 131 of the rotating impeller 13. When the water flows in from the inlet 114, it flows directly into the inlet cylinder 15 through the inlet 151, and then flows out from the outlet 153 of the inlet cylinder 15. The water flowing out from the outlet 153 directly impacts the blade 131, which helps the water flow drive the rotating impeller 13 to rotate.

[0041] Furthermore, such as Figure 5 As shown, each of the drain outlets 153 is connected to an adjusting plate 154 on one side, and the position of each adjusting plate 154 relative to the cylinder wall 152 can be adjusted. Specifically, the cylinder wall 152 of the water inlet cylinder 15 is punched, which separates part of the material from the cylinder wall 152 to form a drain outlet 153. Part of the material does not completely detach from the cylinder wall 152, with one side still connected to the cylinder wall 152. This part of the material forms the adjusting plate 154 in this embodiment. A drainage channel for water flow is formed between the adjusting plate 154 and the drain outlet 153. Since the water inlet cylinder 15 is made of metal, the position of the adjusting plate 154 relative to the cylinder wall 152 can be adjusted. Adjusting the position of the adjusting plate 154 can adjust the size of the drainage channel. When the water flow rate per unit time flowing in from the water inlet 114 remains constant, the closer the adjusting plate 154 is to the cylinder wall 152, the smaller the drainage channel, the greater the impact force of the water flow discharged from the drain outlet 153 on the blade 131, and the faster the rotation speed of the rotating impeller 13. Conversely, the closer the adjusting plate 154 is to the cylinder wall 152, the slower the rotation speed of the rotating impeller 13. Therefore, in this embodiment, by setting an adjusting plate 154 in the water inlet cylinder 15, the position of the adjusting plate 154 can be adjusted according to the rotation speed requirement of the rotating impeller 13 during use.

[0042] Furthermore, such as Figure 2 ,3 As shown, the fixing component is a fixed cylinder 12, one end of which is fixedly connected to the second end plate 113. Specifically, the fixed cylinder 12 and the second end plate 113 are connected by welding. Several through holes 121 are formed on the wall of the fixed cylinder 12. The rotating impeller 13 is disposed at the other end of the fixed cylinder 12, and a ball bearing assembly 16 is provided between the rotating impeller 13 and the fixed cylinder 12. The nozzle assembly 14 is disposed inside the fixed cylinder 12 at one end near the rotating impeller 13. Specifically, it also includes a bolt 18 and a nut 19. The bolt 18 passes through the rotating impeller 13, the ball bearing assembly 16, the fixed cylinder 12, and the nozzle assembly 14 from top to bottom before connecting to the nut 19. The second end plate 113 and the side wall 111 are detachably connected by threads. In this embodiment, the ball bearing assembly 16 helps to reduce the frictional force when the rotating impeller 13 rotates.

[0043] Furthermore, such as Figure 3 As shown, the nozzle assembly 14 includes a connecting cylinder 142 and a nozzle 143. One end of the connecting cylinder 142 is connected to the rotating impeller 13, and the other end extends to the outside of the mounting cylinder 11 and is detachably connected to the nozzle 143. A plurality of connecting holes 144 are provided on the peripheral wall of the connecting cylinder 142, and a plurality of water outlet holes 141 are provided on the nozzle 143. Specifically, the nozzle 143 is a spherical nozzle with a tubular connecting part at its upper end. External threads are provided on the outer wall of the tubular connecting part, and internal threads are provided at the connection point between the connecting cylinder 142 and the tubular connecting part.

[0044] Example 2

[0045] like Figure 6-10 As shown, based on Embodiment 1, this embodiment provides an automatic sprinkler fire protection system, which includes at least one automatic sprinkler device 2; the automatic sprinkler device 2 includes a water pipe 21, a switch 22, and a switch activation mechanism; the inlet end of the water pipe 21 is connected to an external water supply mechanism, and the outlet end is connected to a rotary sprinkler mechanism 1 as described in any one of Embodiment 1; the switch 22 is disposed on the water pipe 21, and the switch 22 is connected to the switch activation mechanism.

[0046] The automatic sprinkler fire suppression system in this embodiment can be applied to large production plants or warehouses. Depending on the specific layout of the production plant or the storage location of the goods in the warehouse, multiple automatic sprinkler devices 2 are installed on the ceiling 20 of the production plant or warehouse. Each automatic sprinkler device 2 is controlled by an independent switch activation mechanism. When a fire occurs at a certain location, the switch 22 of the corresponding automatic sprinkler device 2 will be activated, and the corresponding rotary sprinkler mechanism 1 will spray water at the fire location. Automatic sprinkler devices 2 at other locations will not be activated, allowing for targeted spraying directly at the fire location, ensuring sufficient water volume for effective and rapid fire extinguishing. Furthermore, the rotary sprinkler mechanism 1 used in this embodiment has a simpler structure compared to existing technologies, which helps improve production efficiency, reduce production costs, and effectively reduce the failure rate.

[0047] Furthermore, such as Figure 7-9 As shown, the switch activation mechanism includes a fixing component 231, a first tension spring 232, a first traction rope 233, a second traction rope 234, a connecting rod 235, and a first torsion spring 236. The fixing component 231 is installed on the water pipe 21 near the switch 22. The fixing component 231 includes a fixing base 2311, a fixing rod 2312, and a fixing shaft 2313, both of which are mounted on the fixing base 2311. The switch 22 includes a rotating handle 221, which is located away from the water pipe 21. One end of the water pipe 21 is connected to the connecting rod 235; the first torsion spring 236 is sleeved on the fixed shaft 2313, one end of the first torsion spring 236 is connected to the fixed base 2311, and the other end is connected to the connecting rod 235; one end of the second traction rope 234 is connected to the connecting rod 235, and the other end is connected to the first tension spring 232, with the middle part of the second traction rope 234 wound around the fixed rod 2312; the other end of the first tension spring 232 is connected to the first traction rope 233. Specifically, the first traction rope 233 and the second traction rope 234 are fusible ropes.

[0048] In this embodiment, when no fire occurs, a first torsion spring 236 and a second traction rope 234 are respectively installed at both ends of the connecting rod 235. The second traction rope 234 applies a pulling force to the connecting rod 235 under the action of the first tension spring 232. This pulling force causes the connecting rod 235 to rotate the handle 221 to the closed position, so that the switch 2 remains closed. At this time, the first torsion spring 236 is in a torsional state, such as... Figure 8As shown. When a fire occurs, the first traction rope 233 in the switch activation mechanism corresponding to the fire location is burned off. The first traction rope 233 and the first tension spring 232 no longer exert tension on the connecting rod 235. The first torsion spring 236 returns to its free state. The connecting rod 235 moves under the action of the first torsion spring 236, thereby driving the rotating handle 221 to rotate to the open position. The switch changes from the closed state to the open state, as shown. Figure 9 As shown, at this time, the water in the water pipe 21 flows into the rotary sprinkler mechanism 1, which, driven by the water, rotates while spraying water towards the fire location. Most existing automatic sprinkler fire protection systems use temperature sensors, smoke sensors, etc., to sense changes in surrounding environmental parameters and thus control the activation of the automatic sprinkler fire protection system. However, components such as temperature sensors and smoke sensors are not only costly but also prone to failure. In contrast, the switch activation mechanism in this embodiment is not only low-cost but also highly reliable.

[0049] Furthermore, such as Figure 6 and 10 As shown, the switch activation mechanism also includes a limiting shaft 237 and several stop bars 238. The limiting shaft 237 is located near the safety exit 24. Several stop bars 238 are arranged around the outside of the rotary water spray mechanism 1. One end of each stop bar 238 is a fixed end, and the other end is provided with a stop block 2381. Specifically, the fixed end of each stop bar 238 is fixedly connected to the top 20 of the production plant or warehouse. The stop block 2381 is frustum-shaped to prevent the first traction rope from falling. The other end of the first traction rope 233 passes through several stop bars 238 in sequence and is then connected to the limiting shaft 237. Specifically, a first number plate 25 is suspended on each automatic sprinkler device 2, and different Arabic numerals are set on each of the first number plates 25; at the same time, a number of limiting shafts 237 are set near the safety exit 24, and a second number plate 26 is set on the other end of the first traction rope 233 in each automatic sprinkler device 2, and different Arabic numerals are set on each of the second number plates 26; the Arabic numerals on the first number plate 25 and the second number plate 26 in each automatic sprinkler device 2 are the same, and the other end of each first traction rope 233 is connected to the limiting shaft 237.

[0050] In this embodiment, since the water sprayed by the rotary water spraying mechanism 1 in each automatic sprinkler device 2 covers a certain area, several baffles 238 are set around the outside of the rotary water spraying mechanism 1 so that a first traction rope 233 is set in each direction within the area covered by each automatic sprinkler device 2. This allows the first traction rope 233 corresponding to a certain direction to be quickly burned off when a fire occurs in a certain direction within the covered area, ensuring that the rotary water spraying mechanism 1 in the automatic sprinkler device 2 is activated in time and sprays water onto the area on fire in a timely manner. Furthermore, by installing a first number plate 25 and a second number plate 26 in each automatic sprinkler device 2, and connecting the other end of each first traction rope 233 to a limiting shaft 237 near the safety exit 24, in the event of a fire, personnel inside will evacuate towards the safety exit 24 in a timely manner. Upon reaching the safety exit 24, if it is found that the first traction rope 233 at the location of the fire has not been burned through, the first traction rope 233 with the corresponding second number plate 26 can be located based on the first number plate 25 on the automatic sprinkler device 2 corresponding to the fire area. The first traction rope 233 disengages from the limiting shaft 237, thereby enabling manual operation of the automatic sprinkler device 2 and further ensuring the timeliness of fire extinguishing. If the automatic sprinkler device 2 corresponding to the fire area has been opened, but it is found that the fire is spreading to the surrounding area, the first traction rope 233 with the corresponding second label 26 can be found according to the first label 25 on the automatic sprinkler device 2 corresponding to the surrounding area, and disengage it from the limiting shaft 237, thereby enabling manual operation of the automatic sprinkler device 2 in the surrounding area and effectively preventing the fire from spreading to the surrounding areas.

[0051] Furthermore, such as Figure 10-11 As shown, the automatic sprinkler fire protection system also includes a triggering mechanism 3. The first traction rope 233 in each of the automatic sprinkler devices 2 is connected to the triggering mechanism 3. The automatic sprinkler fire protection system also includes a main power switch 4 and / or an alarm. The triggering mechanism 3 is connected to the main power switch 4 and / or the alarm. When any of the first traction ropes 233 in the automatic sprinkler fire protection system is burned out, the triggering mechanism 3 will be triggered, thereby shutting off the main power switch 4 and / or activating the alarm. This ensures timely shutdown of the main power switch to prevent electric shock due to water on the ground during firefighting and timely activation of the alarm to alert people to evacuate immediately in case of fire. The specific structure of the triggering mechanism 3 is as follows: Figure 10-11As shown, the triggering mechanism 3 includes a mounting housing 30. A plurality of guide cylinders 31 are fixedly mounted on the upper part of the mounting housing 30. Each guide cylinder 31 contains a second tension spring 32 and a trigger rod 33. One end of the second spring 32 is connected to the trigger rod 33, and the other end is connected to one of the traction ropes. A guide plate 34 and at least two guide limiting rods 35 are also fixedly mounted in the mounting housing 30. The guide plate 34 is located below the plurality of guide cylinders 31, and a guide through hole is provided on the guide plate 34 corresponding to the position of each guide cylinder 31. The end of the trigger rod 33 away from the second tension spring 32 extends through the guide through hole to the lower part of the guide plate 34. A protruding ring is provided on the trigger rod 33, and a guide ring and a guide cylinder 31 are provided with a guide through hole. A compression spring 311 is provided. One end of the guide limit rod 35 is fixedly connected to the mounting housing 30, and the other end extends through the guide plate 34 and is provided with a limit block. A trigger plate 36 is also provided on the lower side of the guide plate 34. The trigger plate 36 is slidably mounted on the guide limit rod 35. A rotating frame 37 is rotatably connected to the middle of the trigger plate 36. A support plate 38 is fixedly provided in the mounting housing 10. The middle of the rotating frame 37 is hinged to the support plate 38. A baffle 39 protrudes from the end of the rotating frame 37 away from the trigger plate 36. A screw 310 is connected to the support plate 38. A second torsion spring 5 is sleeved on the screw 310. One end of the second torsion spring 5 is connected to the start handle of the main power switch 4 and / or the start switch of the alarm, and the other end is connected to the support plate 38.Taking the main power switch 4 as an example, the working principle of the trigger mechanism 3 is explained as follows: When the main power switch 4 is turned on, the starter handle flips upward. At this time, the second torsion spring 5 is in a torsional state, pressing the baffle 39 down to abut against one end of the second torsion spring 5, preventing the second torsion spring 5 from returning to its free state, thus keeping the main power switch 4 in the open state. At this time, due to the pushing force exerted by the second torsion spring 5 on the baffle 39, the rotating frame 37 remains in the state of the baffle 39 being pressed down, and the trigger plate 36 is maintained in a position close to the guide plate 34. When there is no fire, the tension of the first traction rope 233 causes the second tension spring 32 to be pulled upward, which drives the trigger rod 33 to move upward. At this time, the compression spring 311 is in a compressed state, and the trigger rod 33 does not exert force on the trigger plate 36, that is, the trigger plate 36 is maintained in a position close to the guide plate 34, thereby keeping the main power switch 4 open. In the event of a fire, if any of the first traction ropes 233 is burned or intentionally detached from the limiting shaft 237, the second tension spring 32 and compression spring 311 return to their free state due to the absence of tension from the first traction ropes 233. Under the action of the elastic force, the trigger rod 33 quickly moves downward to impact the trigger plate 36. The impact force of the trigger rod 33 on the trigger plate 36 is much greater than the pushing force exerted by the second torsion spring 5 on the baffle 39. As a result, the trigger plate 36 moves downward along the guide limiting rod 35 to the position of the limiting block under the impact force. The end of the rotating frame 37 connected to the trigger plate 36 moves downward along with the trigger plate 36. The rotating frame 37 rotates, thereby causing the baffle to move upward and detach from the second torsion spring 5. Without the restriction of the baffle 39, the second torsion spring 5 returns to its free state, thereby causing the start handle of the main power switch 4 to flip downward and turn off the main power switch 4. Of course, in other embodiments, the trigger mechanism 3 can also adopt other structures, as long as it can achieve the triggering function.

[0052] In this embodiment, since the other end of the first traction rope 233 needs to be connected to both the triggering mechanism 3 and the limiting shaft 237, an L-shaped rod 81, a third tension spring 82, and a branch rope 83 are provided near the other end of the first traction rope 233. One end of the third tension spring 82 is connected to the L-shaped rod 81, and the other end is connected to one end of the branch rope 83. The other end of the first traction rope 233 first passes through the L-shaped rod 81, then through one end of the branch rope 83, and then returns to pass through the L-shaped rod 81 before connecting to the triggering mechanism 3, i.e., the first traction... Rope 233 forms a bend, and the other end of branch rope 83 is connected to the limiting shaft 237. At this time, under the tension of branch rope 83, the third tension spring 82 is in a stretched state, where branch rope 83 is a steel wire rope. In actual use, when branch rope 83 is manually disengaged from limiting shaft 237, the third tension spring 82 needs to return to a free state, thereby driving the bend of the first traction rope 233 to move towards the L-shaped rod 81, causing the first traction rope 233 to be relaxed, thus triggering the triggering mechanism 3 and opening the rotary water spray mechanism 1. Based on this, the second label 26 is set on the end of branch rope 83 connected to limiting shaft 237.

The inlet end of the pipe assembly 61 is connected to an external water supply mechanism via a connecting pipe 62, and the outlet end of the pipe assembly 61 is connected to a rotary sprinkler mechanism 1 as described in any one of Embodiment 1. The pipe assembly 61 consists of one or more pipes. When the pipe assembly 61 consists of multiple pipes, adjacent pipes are connected by any one of welding, threaded connection, or sliding sleeve connection. Specifically, the detachable fire protection system is detachably connected to the insertion through-hole 71 via a connecting thread.

[0055] In practical use, when a fire occurs on a floor, a detachable fire suppression system can be quickly installed on the floor above or below through the insertion holes 71 in the floor slab 7 to extinguish the fire. Similarly, when a room catches fire, the detachable fire suppression system can be quickly installed through the insertion holes 71 in the wall to extinguish the fire. Firefighting can be carried out without entering the burning floor or room, ensuring the safety of firefighters. Furthermore, the detachable fire suppression system of this application is highly flexible; it can be installed in the insertion holes 71 at the location of the fire, allowing for direct fire suppression at the fire location, making it more targeted and ensuring a sufficient water volume for better fire suppression. Moreover, the rotary sprinkler mechanism 1 used in this embodiment has a simpler structure compared to existing technologies, which helps improve production efficiency, reduce production costs, and effectively reduce the failure rate.

[0056] Furthermore, the detachable fire protection system also includes a sealing cover 63; the sealing cover 63 is also connected to the insertion hole 71 by threads; in daily life, the sealing covers 63 are installed at both ends of the insertion hole 71 to ensure people's normal life; when fire extinguishing is required, the sealing covers 63 at both ends of the insertion hole 71 at the corresponding positions are removed, and the detachable fire protection system can be installed in the insertion hole for fire extinguishing operations. The specific structure and disassembly method of the sealing cover 63 are the same as those in the applicant's previous invention patent CN115212488B, and will not be described again here.

[0057] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
