Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1

[0023] See also Figure 1-Figure 4 , a fire sprinkler head burst emergency discharge device shown in the figure includes a collection barrel 102 arranged on a bottom plate 101, a water storage tank 103 is arranged on the side of the collection barrel 102 away from the bottom plate 101, two electric push rods 104 for pushing the water storage tank 103 are arranged on the bottom plate 101, and a discharge mechanism for directly discharging the spray water is also provided on the bottom plate 101;

[0024] The discharge mechanism includes a plurality of L-shaped plates 201 fixedly connected to the bottom plate 101, and a fixing ring 202 is fixedly connected to the opposite end of each L-shaped plate 201, and the outer wall of the collecting barrel 102 is fixedly connected to the inner wall of the fixing ring 202. A mounting ring 203 is fixedly connected to the bottom plate 101, and a rotating tube 204 is rotatably connected in the mounting ring 203. The two ends of the rotating tube 204 are rotatably connected to the collecting barrel 102 and the bottom plate 101 respectively, and two winding reels 205 are fixedly connected to the side wall of the rotating tube 204. A drainage pipe 206 is wound on the side wall of the rotating tube 204 located between the two winding reels 205. A limiting mechanism for limiting the drainage pipe 206 is provided on the bottom plate 101, and one end of the drainage pipe 206 is fixed to the side wall of the rotating tube 204, and is communicated with the collecting barrel 102 through the rotating tube 204.

[0025] It should be noted here that: through the setting of the discharge mechanism, the spray water in the collection barrel 102 is released using the drain pipe 206, thereby avoiding the risk of spray water overflowing from the collection barrel 102, and directly discharged to the outside of the building through the drain pipe 206, without the need for secondary discharge, the operation is simple, thereby improving the efficiency of spray water discharge.

[0026] See also Figure 1-Figure 3 The other end of the drain pipe 206 shown in the figure passes through the mounting ring 203 and is provided with a control valve 207 on the side wall;

[0027] It should be noted here that: through the setting of the control valve 207, on the one hand, it is convenient to open and close the drain pipe 206, and on the other hand, through the blocking of the control valve 207, one end of the drain pipe 206 can be against the side wall of the mounting ring 203, thereby achieving the limitation of the port of the drain pipe 206.

[0028] Working principle for direct discharge of spray water: when emergency discharge of a burst fire sprinkler head is required, the collection bucket 102 on the bottom plate 101 is moved to the bottom of the fire sprinkler head by using the moving wheels, and then the water storage tank 103 is moved close to the fire sprinkler head by using the electric push rod 104, so that the spray water of the burst fire sprinkler head flows from the water storage tank 103 into the collection bucket 102;

[0029] After moving the collection barrel 102 to the bottom of the fire sprinkler head, pull the drain pipe 206. Under the action of force, the drain pipe 206 wound on the side wall of the rotating tube 204 will be continuously pulled out. After the drain pipe 206 is completely pulled out from the mounting ring 203, one end of the drain pipe 206 is placed at the drain outlet of the building or outside the building, and the control valve 207 is opened. The spray water in the collection barrel 102 can be released through the drain pipe 206, thereby avoiding the risk of spray water overflowing from the collection barrel 102, and the water is directly discharged to the outside of the building through the drain pipe 206 without the need for secondary discharge. The operation is simple, thereby improving the efficiency of spray water discharge.

[0030] Example 2

[0031] See also Figure 4 , this embodiment further explains Example 1, the limiting mechanism in the figure includes a fixing plate 301 fixedly connected to the bottom plate 101, the fixing plate 301 is connected to a limiting block 302 on one side close to the rotating tube 204 through an extrusion assembly, a limiting ring 303 is fixedly connected to the side wall of the rotating tube 204, a plurality of limiting grooves 304 are formed on the side wall of the limiting ring 303, and a rounded corner 305 is provided on one end of the limiting block 302 close to the limiting ring 303, and the rounded corner 305 slides on the side wall of each limiting groove 304;

[0032] It should be noted here that: through the setting of the limiting mechanism, during the rotation of the rotating tube 204, the limiting groove 304 on the limiting ring 303 will be driven to rotate. When the side wall of the limiting groove 304 abuts against the limiting block 302, under the interaction force of the fillet 305 and the guiding action of the extrusion component, the limiting block 302 will be pushed away from the rotating tube 204. After the drain pipe 206 is released or stored, the rotating tube 204 stops rotating. At this time, under the elastic action of the extrusion component, the limiting block 302 will be pushed to move close to the limiting ring 303 and abut against the side wall of the limiting groove 304, thereby realizing the limitation of the rotating tube 204 and further limiting the drain pipe 206, thereby ensuring the position stability of the drain pipe 206 during use and storage.

[0033] See also Figure 4 The extrusion assembly shown in the figure includes two symmetrically arranged T-shaped rods 401 slidably connected to the fixed plate 301, one end of the two T-shaped rods 401 is connected to the limit block 302, and the side walls of the two T-shaped rods 401 are sleeved with springs 402, and the two ends of the two springs 402 are respectively connected to the fixed plate 301 and the limit block 302;

[0034] It should be noted here that: the arrangement of the extrusion assembly provides a guiding and limiting function for the movement of the limiting block 302 .

[0035] Example 3

[0036] See also Figure 2 , this embodiment is a further explanation of other embodiments. The bottom plate 101 shown in the figure is provided with a storage mechanism for storing the drain pipe 206. The storage mechanism includes a mounting plate 501 fixedly connected to the bottom plate 101, a storage rod 502 is rotatably connected to the mounting plate 501, one end of the storage rod 502 is fixedly connected to a first bevel gear 503, a connecting rod 504 is rotatably connected to the bottom plate 101, one end of the connecting rod 504 is connected to the rotating tube 204, a second bevel gear 505 is fixedly connected to the side wall of the connecting rod 504, the second bevel gear 505 is meshed with the first bevel gear 503, and the other end of the storage rod 502 is fixedly connected to a crank 506;

[0037] It should be noted here that: through the setting of the storage mechanism, after the spray water is discharged, the first bevel gear 503 at one end of the storage rod 502 is driven to rotate by turning the crank 506, and under the mutual meshing transmission action of the first bevel gear 503 and the second bevel gear 505, the rotating tube 204 is driven to rotate, so that in the process of rotation of the rotating tube 204, the drain pipe 206 is rolled onto the side wall of the rotating tube 204, thereby realizing the storage of the drain pipe 206, reducing the space occupied by the drain pipe 206 and facilitating the next use.
