Description

Technical Field

[0001] This utility model relates to the field of fire-fighting equipment technology, and in particular to a dual-purpose automatic sprinkler intelligent fire-fighting device. Background Technology

[0002] In fire protection engineering construction, fire sprinkler systems are important facilities and come in two forms: manual control and automatic control. These systems are equipped with alarm devices that can automatically sound an alarm when a fire occurs. Automatic fire sprinkler systems, in particular, have the ability to automatically activate sprinklers in the early stages of a fire and coordinate with other fire protection facilities, thereby effectively controlling and extinguishing the fire.

[0003] Chinese patent document CN219681541U discloses an automatic fire sprinkler system for civil buildings. It uses a crossbar that passes through a limiting plate and a housing, and is sleeved with the limiting plate and housing. The limiting plate is fixedly connected to the inner wall of the housing. Through the cooperation of the automatic fire sprinkler structure and the sprinkler heads, the smoke alarm connects to the external power supply of the motor. The motor starts, causing the straight rod to swing left and right, which in turn drives the gear to rotate left and right on the half gear. This causes the crossbar to move left and right within the limiting plate and housing, and simultaneously causes the water pipe to slide left and right on the slide rails machined on the main body, thus moving the sprinkler heads left and right. This allows for repeated large-area extinguishing of fires, enabling the building fire protection equipment to meet fire extinguishing requirements.

[0004] The existing technology has the following problems:

[0005] First, the aforementioned device cannot adjust the height of the sprinkler system according to the fire situation, thus its practicality is limited. Second, during firefighting, the device can only move the sprinkler heads linearly back and forth, which cannot adapt to the fire situation around the device, resulting in an insufficient firefighting range.

[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0029] like Figures 1-6 As shown, a dual-purpose automatic sprinkler intelligent fire-fighting equipment includes a mounting plate 1. Several mounting holes arranged in a ring are opened through the upper edge of the mounting plate 1. Height adjustment components 2 are fixedly installed on the lower left and right sides of the mounting plate 1. Sprinkler adjustment components 3 are fixedly installed at the bottom of the height adjustment components 2.

[0030] The height adjustment assembly 2 includes a water inlet pipe 21. The middle of the outer wall of the water inlet pipe 21 is fixedly connected to the inner wall of the middle of the upper end of the mounting plate 1. A telescopic hose 22 is fixedly installed at the lower end of the water inlet pipe 21. A connecting pipe 23 is fixedly installed at the lower end of the telescopic hose 22. A base plate 24 is fixedly sleeved on the middle of the outer wall of the connecting pipe 23. Rectangular frames 25 with open bottoms are fixedly installed on the left and right sides of the lower end of the mounting plate 1. Slide rails 26 are fixedly installed on the left and right sides of the inner walls of the two rectangular frames 25. Guide frames 27 with open tops are slidably connected to the inner walls of the four adjacent slide rails 26. The lower ends of the two guide frames 27 are fixedly installed on the left and right sides of the upper end of the base plate 24.

[0031] The spray adjustment assembly 3 includes a connector 31, the upper end of which is fixedly connected to the lower end of the connecting pipe 23. Three hoses 32 arranged in a ring are fixedly installed on the outer wall of the connector 31. Spray heads 33 are fixedly installed at the lower ends of the three hoses 32. An automatic adjustment mechanism is movably connected to the bottom of each of the three hoses 32.

[0032] The height adjustment component 2 can extend or shorten the distance between the mounting plate 1 and the chassis 24 according to the fire situation, thereby adjusting the height of the three sprinkler heads 33 from the ground. It can automatically adapt to the height of the fire source and has strong applicability. The sprinkler adjustment component 3 can adjust the operating angle of the three hoses 32 by utilizing the expansion of low-boiling gas. The three sprinkler heads 33 are arranged in a ring, and together with the automatic adjustment mechanism, they achieve circumferential and radial coverage. The high degree of automation enables the equipment to not only spray but also have adjustment functions.

[0033] like Figure 4 As shown, a motor housing 28 is fixedly installed at the rear of the lower right side of the mounting plate 1. The output end of the motor housing 28 passes through the rear of the right rectangular frame 25 and is fixedly sleeved with a bevel gear 29.

[0034] A motor is installed inside the motor housing 28, and the motor receives feedback from the fire detector 4. The output end of the motor housing 28 can drive the first bevel gear 29 to rotate. The second bevel gear 211 drives the internal threaded sleeve 210 to rotate by meshing with the first bevel gear 29. The screw 212 drives the guide frame 27 to slide within the rectangular frame 25 by being threaded to the inner wall of the internal threaded sleeve 210, thereby adjusting the distance between the mounting plate 1 and the base plate 24.

[0035] like Figure 4 As shown, an internally threaded sleeve 210 is rotatably connected to the top of the inner wall of the right rectangular frame 25. A bevel gear 211 is fixedly sleeved on the top of the outer wall of the internally threaded sleeve 210. The outer surface of the bevel gear 211 meshes with the outer surface of the bevel gear 29. A screw 212 is threadedly connected to the inner wall of the internally threaded sleeve 210. The lower end of the screw 212 is fixedly connected to the bottom of the inner wall of the right guide frame 27.

[0036] like Figure 3 As shown, the water inlet pipe 21, the telescopic hose 22, the connecting pipe 23, the connector 31, and the three hoses 32 are connected together.

[0037] The external water pump pumps water from the external water tank into the inlet pipe 21. Water enters the three hoses 32 from the inlet pipe 21, the telescopic hose 22, the connecting pipe 23 and the connector 31, and is then sprayed out by the three spray heads 33.

[0038] like Figure 6 As shown, the automatic adjustment mechanism includes a support cylinder 34, the top of which is rotatably connected to the lower edge of the chassis 24. A piston 35 is slidably connected to the inner wall of the support cylinder 34. The inner cavity of the support cylinder 34 is filled with nitrogen gas at the top of the piston 35. A moving rod 36 is fixedly installed at the bottom of the piston 35. A fixing ring 37 is fixedly connected to the bottom of the outer wall of each hose 32. The bottom of the moving rod 36 is rotatably connected to the outer wall of its corresponding fixing ring 37.

[0039] When the ambient temperature is high, the low-boiling-point nitrogen gas expands within the support cylinder 34. The nitrogen gas overcomes the elastic force of the spring 312, pushing the piston 35 downward. The piston 35 drives the moving rod 36 to move, and the moving rod 36 causes the connected hose 32 to bend. After the hose 32 bends, it causes the sprinkler head 33 on it to change the spray direction. When the temperature is high and the fire spreads, all three hoses 32 bend, and they automatically expand the fire extinguishing range through the lower splash plate 314.

[0040] like Figure 6 As shown, a heat-resistant sleeve 38 is fixedly installed on the side of the outer wall of the support cylinder 34 away from the axis of the connector 31. A slider 39 is slidably connected to the inner wall of the heat-resistant sleeve 38. A support rod 310 is fixedly installed at the bottom of the slider 39. An installation plate 311 is fixedly sleeved on the bottom of the outer wall of the moving rod 36. The bottom of the support rod 310 is fixedly connected to the upper end of the installation plate 311. A spring 312 is fixedly connected to the top of the slider 39. The upper end of the spring 312 is fixedly connected to the top of the inner wall of the heat-resistant sleeve 38.

[0041] As the temperature drops, the nitrogen gradually recovers, and the elastic restoring force of the spring 312 will cause the slider 39, the support rod 310 and the hose 32 to return to their original positions.

[0042] like Figure 5 As shown, a support column 313 is fixedly installed at the lower end of the connector 31, and a conical splash plate 314 is fixedly installed at the lower end of the support column 313 below the three spray heads 33.

[0043] When the three spray heads 33 spray water, the splash plate 314 ensures that the water splashes evenly in all directions.

[0044] like Figure 1 and Figure 5 As shown, a fire detector 4 is fixedly installed at the rear position of the upper left side of the chassis 24.

[0045] The fire detector 4 includes a temperature sensor, a smoke sensor, a thermal imaging sensor, and a flame sensor. The thermal imaging sensor feeds back to the motor housing 28 to locate the fire source position or height, so as to adjust the height of the sprinkler head 33.

[0046] The working principle of this utility model is as follows: In use, the entire device is fixed to the bottom of the ceiling by several mounting holes on the mounting plate 1. The water inlet pipe 21 is connected to an external water pump, which pumps water from the water storage system into the water inlet pipe 21. The water enters the three hoses 32 through the water inlet pipe 21, the telescopic hose 22, the connecting pipe 23, and the connector 31, and is subsequently sprayed out by the three sprinkler heads 33. In the event of a fire, the motor box 28 is activated by the control system based on feedback from the fire detector 4. The output end of the motor box 28 drives the first bevel gear 29 to rotate. The second bevel gear 211 meshes with the first bevel gear 29, driving the internal threaded sleeve 210 to rotate. The screw 212 is threadedly connected to the inner wall of the internal threaded sleeve 210, causing the guide frame 27 to slide within the rectangular frame 25, thereby adjusting the distance between the mounting plate 1 and the base plate 24. This achieves the purpose of adjusting the height of the three sprinkler heads 33 from the ground. It can automatically adapt to the height of the fire source and has strong applicability. When the ambient temperature is high, the low-boiling-point nitrogen gas expands within the support cylinder 34. The nitrogen gas overcomes the elastic force of the spring 312, pushing the piston 35 downward. The piston 35 drives the moving rod 36 to move, and the moving rod 36 causes the connected hose 32 to bend. After the hose 32 bends, it causes the sprinkler head 33 on it to change the spray direction. When the temperature is high and the fire spreads, all three hoses 32 bend, and they automatically expand the fire extinguishing range through the lower splash plate 314.

[0047] This device has two functions: adapting to fire extinguishing and expanding the fire extinguishing range, through two components, making it highly practical.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
