When the two cross bars are away from the two sockets for a distance, the two connecting blocks fixedly installed at the bottom of the cross plate are inserted into the interior of the concave connecting plate until they contact the bottom of its inner wall. At this time, the cross bar and the socket and the through holes opened on the outer wall of the connecting block are on the same horizontal line, and the two handle blocks are no longer squeezed. Under the elastic force of the spring, the two cross bars are simultaneously inside the two sockets and the two through holes, that is, the installation of the splash plate on the sprinkler is completed, the installation process is simplified, and the work efficiency of the staff is improved.

[0023] According to this specific embodiment, the spray mechanism 104 is detachably connected to the mounting mechanism 101, the stabilizing mechanism 102 is fixedly connected to the mounting mechanism 101, each of the expansion plates 108 is fixedly connected to the drive disk 107, the drive disk 107 is fixedly connected to the drive shaft 106, the upper end of the drive shaft 106 is rotatably connected to the spray mechanism 104, the lower end of the drive shaft 106 is fixedly connected to the output end of the motor 105, the motor 105 is fixedly connected to the stabilizing mechanism 102, the upper end of the mounting tube 111 is fixedly connected to the fixing plate 109, the nozzle tube 110 is fixedly connected to the fixing plate 109, and the lower ends of the two support rods 113 are fixed to the support pad 114 The upper end of each support rod 113 is detachably connected to the corresponding plug block 112, and the two plug blocks 112 are fixedly connected to the fixing plate 109. The upper end of each screw rod 116 is fixedly connected to the spray plug 115, and the lower end of each screw rod 116 is fixedly connected to the splash plate 117. The spray plug 115 is rotatably connected to the mounting tube 111. The motor 105 currently provided can drive the drive plate 107 and each expansion plate 108 to rotate, and further pressurizes the water flow after passing through the spray mechanism 104, thereby increasing the splashing distance and expanding the spraying area. This design solves the problem that the range of the splashing water flow is limited, and it is easily limited by range when fire extinguishing and dust reduction are required.

[0024] Among them, the spray mechanism 104 is located below the mounting mechanism 101, the stabilizing mechanism 102 is located below the mounting mechanism 101, each of the expansion plates 108 is respectively located on the peripheral side of the drive disk 107, the drive disk 107 is located on the peripheral side of the drive shaft 106, the upper end of the drive shaft 106 is located at the lower end of the spray mechanism 104, and the motor 105 is located above the stabilizing mechanism 102. When a fire or thick fog occurs, water flows downward from the nozzle pipe 110, passes through the spray plug 115 and flows to the splash plate 117 for splashing. At this time, the motor 105 starts to drive the drive shaft 106 and the drive disk 107. The rotation of the drive disk 107 drives each of the expansion plates 108 to rotate, which can disperse the water flowing through the splash plate 117, expand the spraying area, and reduce the fire or smoke.

The support pad 114 can support the motor 105, facilitate the motor 105 to work better, and also increase the appearance. The mounting tube 111 and the nozzle tube 110 can be disassembled from the fixing plate 109, which is convenient for the staff to repair and replace.

[0026] At the same time, the upper end of each screw rod 116 is located below the spray plug 115, and the lower end of each screw rod 116 is located above the splash plate 117.

This design solves the problem that the splashing water flow has a limited range and is easily limited in range when fire extinguishing and dust reduction are required. When a fire or thick fog occurs, the water flows downward from the nozzle pipe 110, passes through the spray plug 115 and flows to the splash plate 117 for splashing. At this time, the motor 105 is started to drive the driving shaft 106 and the driving disk 107. The rotation of the driving disk 107 drives each of the expansion plates 108 to rotate, and can disperse the water flow flowing through the splash plate 117, expand the spraying area, and reduce the fire or thick smoke. The plug block 112 provides support for the insertion of the support rod 113 The motor 105 is supported when the motor 105 is started, and is prone to shaking or even falling off. After the nozzle pipe 110 is installed, the two support rods 113 are inserted into the corresponding plug blocks 112. The support pads 114 can support the motor 105, facilitate the motor 105 to work better, and also increase the appearance. The mounting tube 111 and the nozzle pipe 110 can be disassembled from the fixing plate 109, which is convenient for the staff to repair and replace. The plurality of screw rods 116 connect the spray plug 115 and the splash plate 117. The splash plate 117 has a plurality of grooves, which can facilitate water splashing. The motor 105 drives the drive plate 107 and the plurality of expansion plates 108, so that the water flying out of the splash plate 117 can be thrown again to increase the spraying area.
