Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fire sprinkler head detection, in particular to a fire sprinkler head detection device. BACKGROUND

[0002] Fire sprinkler heads are widely used in fire sprinkler systems. When a fire occurs, the medium in the glass body of the fire sprinkler head will break when it reaches a certain temperature, and then the valve of the fire water will open. The water flow impacts the sprinkler head splash tray and splashes in all directions to extinguish the fire source. Because the fire sprinkler head is responsible for quickly extinguishing the fire source at the initial stage of the fire, each fire sprinkler head must undergo a complete set of quality detection before leaving the factory to avoid situations such as being unable to use or having poor application effect due to quality problems when a fire occurs. The specific detection items include material detection, performance testing, corrosion resistance testing, pressure resistance testing, high temperature resistance testing, water pressure sealing testing, sprinkler testing, water leakage rate testing, and spray particle size testing.

[0003] The existing method for detecting the temperature resistance of a fire sprinkler head is to connect the fire sprinkler head to be detected to a water flow and then place it in a heating box for heating to detect the sensitivity and burst precision temperature value of the fire sprinkler head. Because the pressure in the pipe of the fire sprinkler system is high, the sprinkler head is connected using a threaded connection to ensure the stability of the connection. When detecting the sprinkler head, the external threads of the sprinkler head are used to install it on the detection device. Because the external threads of the sprinkler head are dense, it takes a long time to operate before and after detection, and the disassembly and assembly are cumbersome, affecting the detection efficiency.

[0004] In addition, when detecting the sprinkler head, the heating box usually uses an electric heating device to heat the entire heating box. However, it takes a certain amount of time for the heat to be transferred to the sprinkler head, affecting the detection speed, and the temperature at different positions in the heating box is not consistent, which reduces the detection accuracy of the sprinkler head.

[0030] Please refer to Figure 5 and Figure 7 In the embodiment, the communication part 4 comprises an L-shaped pipe 41 fixedly connected to the lower part of the pressure plate 316, a connecting ring 42 communicated at the lower end of the vertical segment of the L-shaped pipe 41, an annular butt joint groove 43 opened in the lower end face of the connecting ring 42, and a tapered elastic block 45 slidably connected to the lower part of the connecting ring 42 by a push spring 44, and a circular hole is opened in the middle of the tapered elastic block 45, when the communication part 4 is pressed to descend and abut on the upper part of the spray head by the pressure plate 316, the tapered elastic block 45 abuts on the port of the spray head and deforms to shrink and be clamped into the spray head under the pushing of the pressure plate 316, so as to enhance the sealing between the L-shaped pipe 41 and the spray head, then after the tapered elastic block 45 is completely inserted into the spray head, the connecting ring 42 moves downward until the annular butt joint groove 43 is sleeved on the upper part of the spray head, to further enhance the sealing between the L-shaped pipe 41 and the spray head.

[0031] Referring to Figure 4 In this embodiment, the taking-out member 33 comprises a vertical shaft 331 fixedly connected to the lower end surface of the transverse section of the L-shaped frame 2, a push plate 332 eccentrically arranged inside the annular strip 314 and rotationally connected to the outside of the vertical shaft 331 through a rotating ring, a strip-shaped slot 333 opened in the inside of the annular placement disc 312 and in communication with the gap slot 313 and for the push plate 332 to extend into, a spring telescopic plate 334 fixedly connected to the inner wall of the annular placement disc 312 and located directly above the strip-shaped slot 333, a rectangular ring 335 hingedly connected to the end of the spring telescopic plate 334 and slidingly sleeved outside the push plate 332, and a limiting block fixedly connected to the upper end surface of the push plate 332.

[0032] Since the vertical shaft 331 is eccentrically arranged inside the annular placement disc 312, the distance between the end of the push plate 332 and the strip-shaped slot 333 changes constantly during the rotation of the annular placement disc 312. When the annular placement disc 312 rotates, the rectangular ring 335 is driven to rotate synchronously by the spring telescopic plate 334, and then the push plate 332 is driven to rotate around the vertical shaft 331. After the detection of the shower head is completed, the shower head is located at the front of the annular placement disc 312. Since the center of the vertical shaft 331 and the center of the annular placement disc 312 are eccentric, the end of the push plate 332 is closest to the inside of the annular placement disc 312 at this time, and the push plate 332 pushes the detected shower head out of the gap slot 313, so that the shower head can be quickly taken out of the detection mechanism 3 after the detection is completed. After the shower head is pushed out, the annular placement disc 312 continues to rotate, the distance between the end of the push plate 332 and the inside of the annular placement disc 312 gradually increases, the push plate 332 gradually moves out of the strip-shaped slot 333, and then the limiting block abuts against the rectangular ring 335 and pulls the rectangular ring 335 to move, thereby gradually stretching the spring telescopic plate 334.
