[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0025] Example 1

[0026] See also Figures 1 to 3 As shown, a multifunctional intelligent fire sprinkler includes a multifunctional nozzle assembly 1 and a water supply main assembly 2. The multifunctional nozzle assembly 1 is rotatably connected to the water supply main assembly 2. The water supply main assembly 2 is provided with a power rotation assembly 4 connected to the multifunctional nozzle assembly 1. The power rotation assembly 4 is used to drive the multifunctional nozzle assembly 1 to rotate;

[0027] A connecting mechanism is provided between the multifunctional nozzle assembly 1 and the water supply main assembly 2, which is used to connect the water supply between the multifunctional nozzle assembly 1 and the water supply main assembly 2. An intelligent control unit 3 is provided on the water supply main assembly 2, which is used to intelligently control the power rotation assembly 4 and the water supply main assembly 2.

[0028] The multifunctional assembly 1 includes a multifunctional nozzle assembly housing, a front cover 14 is fixedly connected to the multifunctional nozzle assembly housing, a plurality of nozzles 11 are fixedly mounted on the front cover 14, a plurality of shower holes 13 are provided on the front cover 14, a rear cover 16 is fixedly connected to the multifunctional nozzle assembly housing, an inner cavity 15 is formed between the front cover 14 and the rear cover 16, a plurality of nozzle pipes 17 are provided in the inner cavity 15, and the plurality of nozzle pipes 17 are fixedly connected to the front cover 14 and the rear cover 16, one of the nozzle pipes 17 is in communication with the inner cavity 15, and the other nozzle pipes 17 are fixedly connected to the nozzle 11, and a nozzle water inlet 18 is provided on one side of the nozzle pipe 17;

[0029] The water supply main assembly 2 includes a water supply pipe 27 , one end of which is connected to the nozzle water inlet 18 via a connecting mechanism.

[0030] The nozzle 11 in the multifunctional nozzle assembly 1 is a detachable part, forming a spiral pair with the front cover 14, and can be replaced in batches according to the application time, application scenario, and blockage status. In order to ensure the accuracy of the water column range under the coordination of the nozzle 11 and the pressure, it is necessary to establish a functional relationship between the flow rate of the water column ejected by the nozzle, the nozzle aperture, and the pressure in the pipeline:

[0031]

[0032] Where γ = ρg; Vls is the liquid flow rate at the range Ls, Di is the different nozzle apertures, Vj is the liquid flow rate at the outlet, P is the pressure at the outlet, g is the acceleration due to gravity, and C is a constant.

[0033] The connecting mechanism includes a tower-shaped connecting warehouse 25 fixedly connected to the water supply pipe 27, and the tower-shaped connecting warehouse 25 is fixedly connected to the tower-shaped connecting warehouse 25 by a connecting bolt 26. One side of the tower-shaped connecting warehouse 25 is fixedly connected to the water supply main body outlet pipe 28, and a spring 24 is fixedly connected inside the water supply main body outlet pipe 28. One end of the spring 24 is fixedly connected to an open conical cap 23 that is slidingly connected to the water supply main body outlet pipe 28. The outer surface of the tower-shaped connecting warehouse 25 is rotatably connected to the outer shell of the multi-functional nozzle assembly.

[0034] The water outlet pipe 28 of the water supply main body assembly 2 is provided with a spring 24 and an open conical cap 23. Under the action of the spring 24, the open conical cap 23 is sealed with the nozzle water inlet 18 with a pre-tightening force F′, thereby ensuring the tightness of the water pipe connection.

[0035] Furthermore, when the multifunctional nozzle assembly 1 rotates, the open conical cap 23 in the water supply main assembly 2 generates a resistance torque T0 on the multifunctional nozzle due to the action of the spring 24. In order to ensure the relative rotation of the two components, the driving torque calculation formula is as follows:

[0036]

[0037] Where Td is the driving torque, lo is the distance between the axis of the water supply main outlet pipe and the axis of the central connecting shaft, f is the friction coefficient between the open conical cap 23 and the rear cover 16, and R is the pitch circle radius of the large gear 43.

[0038] When the multi-function nozzle assembly 1 is driven to rotate by the power rotation assembly 4, the open conical cap 23 in the water supply main assembly 2 generates a resistance torque T0 on the multi-nozzle 11 due to the action of the spring 24. In order to ensure the relative rotation of the two assemblies, the driving torque calculation formula is as follows

[0039]

[0040] Where Td is the driving torque, l ois the distance between the axis of the water outlet pipe 28 of the water supply body and the axis of the central connecting shaft 22, f is the friction coefficient between the open conical cap 23 and the rear cover plate 16, and R is the pitch circle radius of the large gear 43.

[0041] When the water supply main assembly 2 and the nozzle 11 rotate relative to each other, under the action of the driving torque Td, the open conical cap 23 is squeezed into the water supply main body outlet pipe 28, and the water supply main assembly 2 and the multi-function nozzle assembly 1 complete the rotation; when the relative rotation of the two components stops, in order to ensure that the axis of the open conical cap 23 is collinear with the axis of the nozzle water inlet 18, the calculation formula for the rotation angle of the pinion 42 is established as follows:

[0042]

[0043] Where θ s is the rotation angle of the small gear 42, Rb is the radius of the large gear 43, Rs is the radius of the small gear 42, k is the number between the current nozzle 11 and the nozzle 11 to be converted, and Np is the number of nozzles 11 on the circumference line of the same diameter.

[0044] A lubricating oil passage 20 is provided at the rotational connection between the tower-shaped connecting chamber 25 and the housing of the multifunctional nozzle assembly, and a tower-shaped cavity 21 is formed in the tower-shaped connecting chamber 25 .

[0045] The power rotation component 4 includes a motor 44 fixedly connected to the water supply main component 2. The motor 44 is controlled by a PLC programming program to control the rotation angle of the motor 44. The output of the motor 44 is fixedly connected to the gear shaft through a coupling 41. A small gear 42 is fixedly sleeved on the gear shaft. The outer surface of the small gear 42 is meshed with a large gear 43 fixedly connected to the multi-functional nozzle assembly 1. The small gear 42 is driven to rotate by the motor 44, and the small gear 42 drives the multi-functional nozzle assembly 1 to rotate through the large gear 43.

[0046] A central connecting shaft 22 is provided on the water supply main assembly 2 , and the outer surface of the central connecting shaft 22 is rotatably connected to both the front cover plate 14 and the rear cover plate 16 through the connecting sleeve 10 and the bearing 12 .

[0047] After the multifunctional intelligent fire sprinkler rack is connected to the fire equipment rack, the water supply pipe 27 is connected to the water outlet pipe of the fire equipment through the conversion joint. When it is necessary to select a replacement of the sprinkler according to different scenarios, the multifunctional nozzle assembly shell is driven to rotate by the power rotation component 4, and the multifunctional nozzle assembly shell drives the front cover 14 and the rear cover 16 to rotate, thereby driving the nozzle 11 and the nozzle pipe 17 on the front cover 14 to rotate, so that the corresponding nozzle 11 and the nozzle pipe 17 are rotated to the position of the open conical cap 23, and then the nozzle pipe 17 of the open conical cap 23 is embedded in the nozzle water inlet 18 under the action of the spring 24, completing a tight connection to ensure reverse flow of water; then water is supplied to the water supply pipe 27, and the water supply pipe 27 supplies water to the tower-shaped connecting compartment 25, and the water supply pipe 27 is inside The inflowing fluid enters the water supply pipe 27 through the tower-shaped connecting chamber 25. The cross-sectional area of ​​the fluid flowing through the node in the tower-shaped connecting chamber 25 becomes larger, and the flow rate is reduced to alleviate the impact of the water flow on the structural parts. Then the water supply pipe 27 supplies water to the open conical cap 23, and the open conical cap 23 supplies water to the water inlet 18 of the nozzle 11. The nozzle water inlet 18 supplies water to the nozzle pipe 17, and the nozzle 11 sprays water to realize the water supply connection of the nozzle 11. At the same time, the nozzle 11 is replaced. When other types of nozzles need to be replaced, when the multi-functional nozzle assembly rotates, under the action of the rotational torque, the open conical cap 23 is pressed into the water outlet pipe 28 of the water supply body, waiting to be embedded in the nozzle water inlet next time, so that the fire sprinkler can automatically replace different nozzles 11, so that the fire sprinkler can be suitable for different scenarios.

[0050] The Internet of Things control unit 33 is equipped with an alarm system. The remote management control system, the cloud platform monitoring system and the Internet of Things control unit 33 are interconnected through the network. After the multifunctional intelligent fire sprinkler rack is connected to the fire equipment rack, the water supply pipe 27 is connected to the water outlet pipe of the fire equipment through a conversion joint. After the power is turned on, the parameters such as the water column range and water volume are provided according to the information collected by the intelligent fire equipment system and transmitted to the Internet of Things control unit 33.
