Description

Technical Field

[0001] This application relates to the field of fire protection equipment technology, specifically a water spray fire extinguishing device. Background Technology

[0002] A water mist fire suppression system is a fire suppression system consisting of a water source, water supply equipment, pipelines, deluge valve assemblies, filters, and water mist nozzles. Its working principle is to use water mist nozzles to separate the water flow into fine water droplets no larger than 1 mm, or even smaller, under high water pressure, and then spray them onto the surface of the burning material to produce a fire extinguishing effect. The mechanism of water mist fire suppression mainly includes four actions: surface cooling, asphyxiation, emulsification, and dilution.

[0003] When installing a water mist fire extinguishing system, the indoor components are usually pipes and water mist nozzles. The existing method for installing and laying pipes is to fix the pipes to the building structure with bolts, steel clamps, or hoops. This method is not adjustable and is more troublesome and less flexible for certain special buildings, thus having certain shortcomings.

[0004] Therefore, this application provides a water spray fire extinguishing device to solve the above-mentioned problems. Utility Model Content

[0005] This application provides a water spray fire extinguishing device, which aims to solve the problems mentioned in the background art. The existing methods mostly fix the pipes to the building with bolts through steel clamps or hoops, which cannot be adjusted. For some special buildings, this method is more troublesome to install, has poor flexibility, and has certain shortcomings.

[0006] To achieve the above objectives, this application provides the following technical solution: a water mist fire extinguishing device, comprising a pipe, a water mist nozzle fixedly installed on the pipe, and a support mechanism disposed on the pipe for flexibly fixing the pipe.

[0007] The support mechanism includes a C-shaped steel beam and a rotating rod movably installed within the C-shaped steel beam. Both ends of the rotating rod are rotatably mounted with wheels. A hanger rod extending beyond the C-shaped steel beam is fixedly installed at the middle position of the rotating rod. A hanging block is rotatably mounted at the end of the hanger rod away from the rotating rod. The hanging block has an installation cavity adapted to the pipe, and a bolt threaded through the installation cavity is screwed onto the hanging block. Thus, during pipe installation, the C-shaped steel beam is fixed to the building surface, the pipe is inserted into the installation cavity of the hanging block, and then the bolt is inserted to support and fix the bottom of the pipe. Subsequently, the hanging block is pushed, causing the wheels to rotate on the rotating rod, thereby moving the wheels within the C-shaped steel beam and quickly adjusting the pipe's installation position. Then, the pipe can be rotated, causing the hanging block to rotate on the hanging rod, thereby adjusting the pipe's installation angle. Compared to existing fixed mounting brackets, this is more flexible and adjustable, facilitating installation and maintenance.

[0008] Preferably, for fixation, the inner wall of the C-shaped steel beam is provided with a toothed groove, and the rotating wheel is gear-shaped and adapted to the toothed groove, and the rotating wheel is rolled on the toothed groove. The toothed groove can hold the rotating wheel in place to a certain extent, thereby achieving a fixing effect.

[0009] Preferably, to prevent the rollers from deviating, two symmetrically arranged limiting plates, with a height higher than the toothed grooves, are fixedly installed on the inner wall of the C-shaped steel beam between the opposing surfaces of the two rollers. This makes the movement trajectory of the rollers more stable.

[0010] Preferably, to secure the C-shaped steel beam, a mounting plate for docking with the building is fixedly installed on the C-shaped steel beam, and the mounting plate has a plurality of evenly spaced fixing holes. This is convenient and quick.

[0011] Preferably, for securing the equipment, the fire extinguishing device further includes a clamping mechanism. The clamping mechanism includes a sleeve fitted onto the boom between the C-shaped steel beam and the boom block. One end of the sleeve is fixedly fitted with a top plate positioned on the boom facing the bottom of the C-shaped steel beam. The other end of the sleeve is fixedly fitted with a support plate positioned on the boom facing the top of the boom block. A spring, fitted onto the outside of the boom, is movably installed between the bottom of the support plate and the top of the boom block. This clamps the rotating wheel onto the toothed groove, preventing accidental movement and ensuring greater stability and reliability.

[0012] This fire extinguishing device fixes a C-shaped steel beam to the building surface, inserts a pipe into the mounting cavity of the hanging block, and then inserts bolts to support and fix the bottom of the pipe. Subsequently, the hanging block is pushed, and the rotating wheel rotates on the rotating rod, thereby moving the rotating wheel within the C-shaped steel beam to quickly adjust the installation position of the pipe. Then, the pipe can be rotated, and the pipe drives the hanging block to rotate on the hanging rod, thereby adjusting the installation angle of the pipe. Compared with the existing fixed mounting brackets, it is more flexible and adjustable, and easier to install and maintain.

[0013] This fire extinguishing device features a pull-down bracket that compresses a spring, causing the top plate on the sleeve to move downwards and detach from the bottom of the C-shaped steel beam. At this point, the rotating wheel can be moved by pushing the lifting block. After adjusting to the appropriate position, the bracket is released, and the spring automatically rebounds, lifting the bracket and causing the top plate on the sleeve to be pushed upwards and reset to abut against the bottom of the C-shaped steel beam. This clamps the rotating wheel onto the toothed groove, preventing accidental movement and ensuring greater stability and reliability. Attached Figure Description

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0022] Example 1

[0023] This embodiment provides a water spray fire extinguishing device, such as Figure 1-5 As shown, the fire extinguishing device includes a pipe 1, a water mist nozzle 2 fixedly installed on the pipe 1, and a support mechanism 3 installed on the pipe 1 for flexibly fixing the pipe 1.

[0024] The support mechanism 3 includes a C-shaped steel beam 31 and a rotating rod 32 movably installed inside the C-shaped steel beam 31. Both ends of the rotating rod 32 are rotatably mounted with rotating wheels 33. A hanging rod 34 extending outside the C-shaped steel beam 31 is fixedly installed at the middle position of the rotating rod 32. A hanging block 35 is rotatably mounted on the end of the hanging rod 34 away from the rotating rod 32. The hanging block 35 has an installation cavity 36 adapted to the pipe 1. A bolt 37 that passes through the installation cavity 36 is screwed onto the hanging block 35.

[0025] In use, the C-shaped steel beam 31 is fixed to the building surface, the pipe 1 is inserted into the mounting cavity 36 of the hanging block 35, and then the bolt 37 is inserted to support and fix the bottom of the pipe 1. Then, the hanging block 35 is pushed, and the rotating wheel 33 rotates on the rotating rod 32, thereby moving the rotating wheel 33 within the C-shaped steel beam 31 to quickly adjust the installation position of the pipe 1. Subsequently, the pipe 1 can be rotated, and the pipe 1 drives the hanging block 35 to rotate on the hanging rod 34, thereby adjusting the installation angle of the pipe 1. Compared with the existing fixed mounting bracket, it is more flexible and adjustable, and easier to install and maintain.

[0026] Specifically, the inner wall of the C-shaped steel beam 31 is provided with a toothed groove 38, and the rotating wheel 33 is gear-shaped and adapted to the toothed groove 38. The rotating wheel 33 is rolled on the toothed groove 38. In use, pushing the lifting block 35 causes the rotating wheel 33, which rotates with the lifting rod 34, to move within the toothed groove 38. After moving to the designated position, the toothed groove 38 can lock the rotating wheel 33 to a certain extent, thereby achieving a fixing effect.

[0027] More specifically, two symmetrically arranged limiting plates 39, with a height higher than that of the toothed groove 38, are fixedly installed on the inner wall of the C-shaped steel beam 31 between the opposing surfaces of the two rotating wheels 33. In use, when the rotating wheels 33 are rotated, the limiting plates 39 block the rotating wheels 33 from the inside, preventing the rotating wheels 33 from wobbling left and right and dislodging from the C-shaped steel beam 31, and making the movement trajectory of the rotating wheels 33 more stable and easier to adjust.

[0028] Furthermore, an mounting plate 310 for docking with the building is fixedly installed on the C-shaped steel beam 31. The mounting plate 310 has a plurality of fixing holes 311 evenly distributed on it. In use, the mounting plate 310 is attached to the building surface and fixed through the fixing holes 311, thereby fixing the C-shaped steel beam 31.

[0029] Example 2

[0030] Unlike Embodiment 1, if the rotating wheel 33 is not fixed after it moves, it may shift. Therefore, the fire extinguishing device also includes a clamping mechanism 4. The clamping mechanism 4 includes a sleeve 42 sleeved on the rod 34 between the C-shaped steel beam 31 and the lifting block 35. One end of the sleeve 42 is fixedly installed with a top piece 41 sleeved on the rod 34 facing the bottom of the C-shaped steel beam 31. The other end of the sleeve 42 is fixedly installed with a support piece 43 sleeved on the rod 34 facing the top of the lifting block 35. A spring 44 sleeved on the outside of the rod 34 is movably installed between the bottom of the support piece 43 and the top of the lifting block 35.

[0031] In use, pull down the support plate 43, which compresses the spring 44, causing the top plate 41 on the sleeve 42 to move down and disengage from the bottom of the C-shaped steel beam 31. At this time, the rotating wheel 33 can be moved by pushing the lifting block 35. After adjusting to the appropriate position, release the support plate 43, and the spring 44 will automatically rebound, lifting the support plate 43 and pushing the top plate 41 on the sleeve 42 upward to reset it and abut against the bottom of the C-shaped steel beam 31, thereby clamping the rotating wheel 33 on the toothed groove 38 to prevent accidental movement and make it more stable and reliable.

[0032] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
