Description

Technical Field

[0001] This utility model relates to the field of sprinkler technology, specifically to a fire sprinkler device. Background Technology

[0002] Fire sprinkler systems are a type of water-spraying fire extinguishing system, typically used to protect the fire safety of buildings, factories, warehouses, and other places. Fire sprinkler systems not only play a crucial role in the early stages of a fire, reducing fire losses, but also effectively improve the fire safety of buildings.

[0003] According to a public disclosure of a fire sprinkler system (Publication No.: CN 221673286 U), it includes a base plate, a water tank, and a sprinkler structure. The water tank is fixedly installed on the top surface of the base plate, and the sprinkler structure is installed in the water tank. The sprinkler structure includes a water pump and a fixing rod. The water pump is installed inside the water tank, and the fixing rod is fixedly installed on the top surface of the base plate. The fixing rod is provided with a fixing ring, and a water pipe is provided on the top of the water pump.

[0004] The above-mentioned method, which relies on the interaction between components such as the water pump and the fixing rod, is insufficient to ensure that the nozzles can cover different locations of the fire source. This results in an inadequate fire suppression coverage area and the fire source being missed due to the fixed nozzle position, which needs to be improved. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides a fire sprinkler device, which solves the technical problem that the sprinkler heads cannot cover different locations of the fire source in the prior art.

[0006] According to one aspect, at least one embodiment of the present invention provides a fire sprinkler device, including a zone plate, a support leg fixedly connected to the top of the zone plate, a sprinkler intermittent adjustment component provided on the top of the support leg, the sprinkler intermittent adjustment component including a mounting frame, the bottom of the mounting frame fixedly connected to the top of the support leg, a motor fixedly connected to the inner wall of the mounting frame, a threaded rod fixedly connected to the output shaft of the motor, a threaded sleeve threadedly connected to the circumferential surface of the threaded rod, a thin rod fixedly connected to the side of the motor, the end of the thin rod away from the motor passing through the side of the threaded sleeve, an actuating rod fixedly connected to the side of the threaded sleeve, a fixing column rotatably connected to the top of the mounting frame, a connecting water pipe passing through the outer wall of the fixing column, a nozzle passing through one end of the connecting water pipe, a support plate fixedly connected to the inner wall of the mounting frame, the bottom of the connecting water pipe slidably connected to the top of the support plate, a spring fixedly connected to the side of the support plate, the end of the spring away from the support plate fixedly connected to the outer wall of the connecting water pipe.

[0007] For example, in a fire sprinkler device provided in at least one embodiment of the present invention, the device further includes: the connecting water pipe is located on the displacement trajectory of the trigger rod, a one-way valve is provided on the outer wall of the connecting water pipe, and a switch is provided on the outer wall of the motor. The design of the one-way valve is beneficial for controlling the water volume of the connecting water pipe.

[0008] For example, in a fire sprinkler device provided in at least one embodiment of the present invention, the threaded rod, threaded sleeve, and thin rod are located on the inner wall of the mounting frame, and a smoke sensor is provided on the top of the mounting frame. The smoke sensor is located on the inner wall of the mounting frame and can be protected to prevent damage caused by external interference.

[0009] For example, in at least one embodiment of the present invention, a fire sprinkler device is provided, which further includes: two smoke sensors are provided and are symmetrical to each other along the vertical central axis of the mounting bracket, and the nozzle is located on the side of the smoke sensor. The smoke sensor is provided to detect smoke and provide timely fire extinguishing spray.

[0010] For example, in a fire sprinkler device provided in at least one embodiment of the present invention, the device further includes: a plurality of legs are provided, arranged in pairs and symmetrical to each other along the vertical central axis of the mounting frame; the support plate is located on the side of the trigger rod; and the provision of a plurality of legs is beneficial for providing stable support.

[0011] According to another aspect, at least one embodiment of the present invention also provides a fire sprinkler device, comprising: a cleaning and scraping assembly provided on the side of the mounting frame, the cleaning and scraping assembly including a rectangular frame, the side of the rectangular frame being fixedly connected to the side of the mounting frame, a movable rod being slidably connected to the inner wall of the rectangular frame, a rotating shaft being rotatably connected to the bottom of the movable rod, a scraper being fixedly connected to the circumferential surface of the rotating shaft, a crossbar being fixedly connected to the side of the threaded sleeve, and a driving rod being fixedly connected to the bottom of the crossbar. The scraper scrapes the groove of the sprinkler head to remove scale and prevent scale from corroding the sprinkler head and causing damage.

[0012] For example, in a fire sprinkler device provided in at least one embodiment of the present invention, the moving rod is located on the displacement trajectory of the driving rod, the scraper is located on the side of the nozzle, and the nozzle is located on the displacement trajectory of the scraper. This design is beneficial for scraping the surface of the nozzle when the scraper moves.

[0013] For example, in at least one embodiment of the present invention, a fire sprinkler device is provided, which further includes: a second spring fixedly connected to the inner wall of the rectangular frame, and the end of the second spring away from the rectangular frame is fixedly connected to the side of the moving rod. The design of the second spring is beneficial to the automatic reset of the moving rod when it is not compressed.

[0014] For example, in at least one embodiment of the present invention, a fire sprinkler device is provided, which further includes: a slot is provided on the side of the movable rod, and a limiting rod is rotatably connected to the side of the rotating shaft. The slot is located on the displacement trajectory of the limiting rod, and the design of the limiting rod is beneficial for temporarily locking the position of the scraper rod.

[0015] For example, in at least one embodiment of the present invention, a fire sprinkler device further includes: a round rod fixedly connected to the inner wall of the rectangular frame, the end of the round rod away from the rectangular frame passing through the side of the movable rod. The design of the round rod is beneficial to restrict the movement trajectory of the movable rod and prevent deviation of the movement trajectory of the movable rod.

[0016] The beneficial effects of the embodiments of this utility model are as follows: In this invention, the intermittent spray adjustment component utilizes the coordinated operation of components such as the motor, threaded rod, threaded sleeve, trigger rod, and spring to flexibly adjust the nozzle position via motor drive and the threaded rod system. This ensures the nozzles cover different locations of the fire source, guaranteeing a wider fire suppression coverage and preventing any missed fire sources due to fixed nozzle positions. The spring's reset mechanism ensures the connecting water pipe automatically returns to its initial position after adjustment, reducing human intervention, enhancing system stability and reliability, and preventing system malfunctions. The nozzles can be adjusted and swung to increase the spray coverage area. Therefore, the spray system can adapt to fires of different sizes, not being limited to fixed spray positions, thus maximizing the fire suppression effect.

[0017] This invention utilizes the coordinated operation of components such as the scraper, drive rod, moving rod, and spring within the cleaning and scraping assembly. By moving the scraper, the device automatically cleans water stains and scale from the nozzle surface, ensuring the nozzle remains clean during use. This effectively prevents the accumulation of scale, impurities, or water stains, thereby improving nozzle efficiency and avoiding clogging or uneven water spraying. Long-term accumulation of scale and other contaminants on the nozzle can cause damage or corrosion, affecting its performance. Regular cleaning reduces this corrosion. When the scraper no longer needs cleaning, the limiting rod locks it in a suitable position, preventing it from interfering with the normal operation of the nozzle and ensuring the system does not interfere with the spraying function during cleaning.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0022] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product.

[0027] like FIG. 1-FIG. 6As shown, this invention illustrates a fire sprinkler system according to one embodiment, comprising a zone plate 1, a support leg 2 fixedly connected to the top of the zone plate 1, a sprinkler intermittent adjustment component 3 disposed on the top of the support leg 2, the sprinkler intermittent adjustment component 3 including a mounting frame 31, the bottom of the mounting frame 31 fixedly connected to the top of the support leg 2, a motor 32 fixedly connected to the inner wall of the mounting frame 31, a threaded rod 33 fixedly connected to the output shaft of the motor 32, a threaded sleeve 34 threadedly connected to the circumferential surface of the threaded rod 33, and a thin rod 35 fixedly connected to the side of the motor 32. One end of the motor 32 passes through the side of the threaded sleeve 34. An actuating rod 36 is fixedly connected to the side of the threaded sleeve 34. A fixed column 38 is rotatably connected to the top of the mounting bracket 31. A connecting water pipe 311 passes through the outer wall of the fixed column 38. A nozzle 310 passes through one end of the connecting water pipe 311. A support plate 37 is fixedly connected to the inner wall of the mounting bracket 31. The bottom of the connecting water pipe 311 is slidably connected to the top of the support plate 37. A spring 39 is fixedly connected to the side of the support plate 37. The end of the spring 39 away from the support plate 37 is fixedly connected to the outer wall of the connecting water pipe 311.

[0028] In some examples, the connecting water pipe 311 is located on the displacement trajectory of the trigger rod 36, and a one-way valve 312 is provided on the outer wall of the connecting water pipe 311, and a switch 313 is provided on the outer wall of the motor 32. The design of the one-way valve 312 is beneficial to control the water volume of the connecting water pipe 311.

[0029] In some examples, the threaded rod 33, threaded sleeve 34, and thin rod 35 are located on the inner wall of the mounting bracket 31. A smoke sensor 314 is installed on the top of the mounting bracket 31 and is located on the inner wall of the mounting bracket 31 to protect it from damage caused by external interference.

[0030] In some examples, there are two smoke sensors 314, which are symmetrical to each other along the vertical central axis of the mounting bracket 31. The nozzle 310 is located on the side of the smoke sensor 314. The presence of smoke sensors 314 is beneficial for detecting smoke and providing timely spray fire suppression.

[0031] In some examples, there are several legs 2 arranged in pairs and symmetrical to each other along the vertical central axis of the mounting frame 31. The support plate 37 is located on the side of the actuating rod 36. The arrangement of several legs 2 helps to provide stable support.

[0032] For example, such as FIG. 1-FIG. 6As shown, the smoke sensor 314 facilitates the detection of smoke and enables timely sprinkler fire suppression. When sprinkler fire suppression is required, water is delivered to the connecting water pipe 311 through an external water supply pipe, and then flows to the sprinkler head 310, from which water is sprayed. The connecting water pipe 311 is interconnected with the fixing column 38, which fixes and restricts the position of the connecting water pipe 311. The connecting water pipe 311 is slidably connected to the top of the support plate 37. The initial state of the connecting water pipe 311 is at the top of the support plate 37. When the position of the sprinkler head 310 needs to be adjusted... When the switch 313 is pressed, the motor 32 is started and rotated forward. The forward rotation of the motor 32 drives the threaded rod 33 to rotate forward. The forward rotation of the threaded rod 33 will drive the threaded sleeve 34 and the trigger rod 36 to move closer to the nozzle 310. The nozzle 310 and the connecting water pipe 311 are located on the movement trajectory of the trigger rod 36. A spring 39 is provided on the outer wall of the connecting water pipe 311. When the trigger rod 36 is activated, it will squeeze the connecting water pipe 311, causing the connecting water pipe 311 to slide on the top of the support plate 37. The sliding of the connecting water pipe 311 will squeeze the spring 39. When compressed, the spring 39 automatically resets the nozzle, causing the fixed post 38 to rotate on top of the mounting bracket 31. Displacement of the connecting water pipe 311 causes the nozzle 310 to slide, adjusting its position and allowing it to oscillate, increasing the sprayable area. The spring 39's reset mechanism allows the connecting water pipe 311 to slide multiple times, enabling the nozzle 310 to oscillate as needed, allowing for intermittent adjustment. Driven by the motor 32 and the threaded rod 33 system, the position of the nozzle 310 can be flexibly adjusted, ensuring... The sprinkler head 310 can cover different locations of the fire source, ensuring a wider fire suppression coverage area and preventing any fire source from being missed due to the fixed position of the sprinkler head 310. The reset mechanism of the spring 39 ensures that the connecting water pipe 311 can automatically return to its initial position after adjustment. This mechanism reduces human intervention, enhances the stability and reliability of the system, and prevents system failure. The sprinkler head 310 can be adjusted and swung to increase the coverage area. In this way, the sprinkler system can adapt to fires of different sizes and is not limited to fixed spray positions, maximizing the fire suppression effect.

[0033] like FIG. 1-FIG. 6As shown, this invention illustrates a fire sprinkler device according to another embodiment of the present invention, comprising: a cleaning and scraping assembly 4 provided on the side of a mounting frame 31, the cleaning and scraping assembly 4 including a rectangular frame 41, the side of the rectangular frame 41 being fixedly connected to the side of the mounting frame 31, a movable rod 42 being slidably connected to the inner wall of the rectangular frame 41, a rotating shaft 45 being rotatably connected to the bottom of the movable rod 42, a scraper 46 being fixedly connected to the circumferential surface of the rotating shaft 45, a crossbar 43 being fixedly connected to the side of a threaded sleeve 34, and a driving rod 44 being fixedly connected to the bottom of the crossbar 43. The scraper 46 scrapes the groove of the nozzle 310 to remove scale and prevent scale from corroding the nozzle 310 and causing damage. In some examples, the moving rod 42 is located on the displacement trajectory of the driving rod 44, the scraper 46 is located on the side of the nozzle 310, and the nozzle 310 is located on the displacement trajectory of the scraper 46. This design is beneficial for scraping the surface of the nozzle 310 when the scraper 46 moves.

[0034] In some examples, a second spring 49 is fixedly connected to the inner wall of the rectangular frame 41. The end of the second spring 49 away from the rectangular frame 41 is fixedly connected to the side of the moving rod 42. The design of the second spring 49 is conducive to the automatic reset of the moving rod 42 when it is not compressed.

[0035] In some examples, the side of the moving rod 42 is provided with a slot 48, and the side of the rotating shaft 45 is rotatably connected to a limiting rod 47. The slot 48 is located on the displacement trajectory of the limiting rod 47. The design of the limiting rod 47 is beneficial for temporarily locking the position of the scraper 46.

[0036] In some examples, a round rod 410 is fixedly connected to the inner wall of the rectangular frame 41. The end of the round rod 410 away from the rectangular frame 41 passes through the side of the movable rod 42. The design of the round rod 410 helps to limit the movement trajectory of the movable rod 42 and prevent the movement trajectory of the movable rod 42 from deviating.

[0037] For example, such as FIG. 1-FIG. 6As shown, when the nozzle 310 does not require adjustment, the motor 32 is started, causing it to reverse, which in turn reverses the threaded rod 33. The reverse rotation of the threaded rod 33 causes the threaded sleeve 34 and the moving rod 44 to move away from the connecting water pipe 311. The moving rod 42 is positioned on the trajectory of the moving rod 44. When the moving rod 44 moves, it slides on the inner wall of the rectangular frame 41. The movement of the moving rod 42 causes the rotating shaft 45, the limiting rod 47, the slot 48, and the scraper 46 to move. The scraper 46 is located on the side of the nozzle 310. When the scraper 46 moves, it scrapes the surface of the nozzle 310, removing water stains and scale to prevent scale corrosion and damage. When cleaning is not required, the scraper 46 is rotated upwards along the rotating shaft 45, temporarily moving it away from the nozzle 310. Then, the limiting rod 47 is rotated towards the slot 48, allowing it to pass through the slot 48. The device temporarily locks the positions of the rotating shaft 45 and the scraper 46 to prevent the scraper 46 from interfering with the spraying operation of the nozzle 310. Through the movement of the scraper 46, the device can automatically clean water stains and scale from the surface of the nozzle 310, ensuring that the nozzle 310 remains clean during use. This effectively prevents the accumulation of scale, impurities, or water stains, thereby improving the working efficiency of the nozzle 310 and avoiding clogging or uneven water spraying. Scale and other contaminants accumulating on the nozzle 310 over a long period can cause damage or corrosion, affecting its performance. Regular cleaning can reduce this corrosion, extend the service life of the nozzle 310 and the overall fire protection system, and reduce the frequency of maintenance and replacement of the nozzle 310. When the scraper 46 no longer needs cleaning, the limiting rod 47 will lock the scraper 46 in a suitable position, thus preventing the scraper 46 from interfering with the normal operation of the nozzle 310 and ensuring that the system does not interfere with the spraying function during cleaning.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
