Description

Technical Field

[0001] This utility model relates to the field of fire safety testing technology, specifically a fire sprinkler head testing device. Background Technology

[0002] Fire sprinkler heads are key components in automatic sprinkler systems, and their reliability directly affects the effectiveness of initial fire suppression. Therefore, fire sprinkler head inspection is an indispensable part of fire safety management. Currently, a common inspection method involves locally heating the sprinkler head's heat-sensitive element (usually a heat-sensitive glass bulb or tube) with a heat source (such as a gas-filled flamethrower). When the heat-sensitive element reaches its rated operating temperature, it breaks, triggering the sprinkler head to spray water. Its operational status is determined by observing whether it operates normally. This traditional on-site inspection method has the following problems: after the heat-sensitive glass bulb breaks, the sprinkler head will continue to spray water. Although the pipeline pressure can be reduced beforehand to decrease the water volume, the water sprayed from the sprinkler head will still wet the inspection area, potentially damaging equipment. Furthermore, broken glass fragments may splash and scatter with the water flow, making them difficult to clean up. Furthermore, since sprinkler heads are typically installed on ceilings or at high locations, testing personnel need to use ladders to operate them. To avoid getting wet, they often have to hastily evacuate from these heights, increasing the risk of slipping, falling, and other personal injuries. Additionally, current methods mostly use gas-filled flame guns to directly heat the heat-sensitive elements. While this allows for rapid temperature increases, the flame temperature of these flame guns is high, significantly different from real-world fire conditions. This constitutes an "overheating" impact test and may not accurately simulate the sprinkler head's response performance in a real fire. Summary of the Invention

The end of the electric ignition wire is fixed to the outside of the spray pipe part, and the end extends into the spray pipe part through the ignition slot. The other end is electrically connected to the battery and the control button.

[0008] Furthermore, the gas tank switch assembly includes a limiting plate and a connecting pipe. The limiting plate is fixed on the support plate and has a circular opening at the top. The connecting pipe is a cylindrical tube with one end detachably connected to the torsion switch and the other end passing through the circular opening on the limiting plate.

[0012] This utility model proposes a fire sprinkler head detection device that uses a remotely ignited gas canister spray gun in conjunction with a telescopic rod to heat the heat-sensitive element. A water collection cap on the telescopic rod, along with a water pipe, allows for the collection of spray water. Testing personnel can remotely trigger the heating action from the ground or a safe platform, effectively preventing the risk of slipping or falling due to hasty evacuation caused by sudden sprinkler activation. The water collection cap design effectively collects the sprayed water when the sprinkler head is activated and directs it to a designated drainage point or container via a guide pipe, greatly reducing water damage to the testing site. The heating method employs diffusion heating, which, although slower, more closely resembles the conditions of a real fire. Furthermore, the diffuser baffle also reduces the amount of spray water entering the spray gun pipe. Attached Figure Description

(See attached figure) Figure 5 As shown, a threaded hole is provided on the side of the circular opening 221. After the screw 222 is inserted into the threaded hole, a compression block 223 is provided at its end. The reliable connection between the water cap 4 and the gas tank 31 of the heating unit 3 is achieved by tightening the screw. The compression block is made of a soft material, such as a rubber block.

[0023] The heating unit 3 includes a gas tank 31, a spray gun 32, a gas tank switch assembly 33, and an electric ignition assembly 34.

[0024] The gas tank 31 is detachably mounted on the support plate 22. The spray gun 32 is mounted on the gas tank 31. The spray gun 32 is an existing product in the field and includes a gas tank connection part 321 and a nozzle part 322.

An ignition slot is provided on the upper part of the expansion section p.

[0025] The electric ignition assembly 34 includes an electric ignition wire 341, a battery, and a control button 342. The end of the electric ignition wire 341 is fixed to the outside of the nozzle section 322, and the end extends into the nozzle section 322 through an ignition slot. The other end is electrically connected to the battery and the control button 342.

[0026] The gas tank switch assembly 33 includes a limiting plate 331 and a connecting pipe 332. The limiting plate 331 is fixed to the support plate 22 and has a circular opening at its top.

[0027] The water receiving cap 4 includes an inner water jacket 41, an outer water jacket 42, and a diffuser baffle 43. The inner water jacket 41 and the outer water jacket 42 are funnel-shaped.

[0030] In use, the inner water jacket 41 is fitted over the outside of the sprinkler head. Ignition of the gas is emitted from the expansion section, and heat diffuses through the diffuser hole 431 into the inner water jacket 41. As the temperature rises, the thermal element ruptures, and fire-fighting water sprays from the sprinkler head. Simultaneously, the inspector shuts off the gas cylinder via the gas cylinder switch assembly 33. Spray water enters the inner water jacket 41 and flows out through the water pipe. The diffuser baffle 43 effectively prevents water from entering the expansion section. Water entering the expansion section flows out through the vent hole to the outer water jacket 42, then through the water inlet 421, and finally into the water pipe from the inner water jacket 41.
