Description

Technical Field

[0001] The present invention relates to the technical field of fire sprinkler detection, in particular to a fire sprinkler fault detection device. Background Art

[0002] Fire sprinklers are the core components of automatic fire extinguishing systems. When a fire breaks out, they automatically activate when a certain temperature is reached, spraying water to control the fire. Therefore, fire sprinkler fault detection is particularly important. Inspectors regularly test fire sprinklers to ensure they are functioning properly. However, there are still many inconveniences in the actual inspection process: First, the temperature is not easy to control. At present, in order to adapt to different working environments, the heat-sensitive liquids contained in the glass tubes of fire sprinklers are also divided into different colors. The commonly used colors on the market are orange, red, yellow and green, and the corresponding glass tube trigger temperatures are 57 degrees, 68 degrees, 79 degrees and 93 degrees respectively. The explosion of glass tubes of different colors requires different temperatures. However, it is difficult to control the temperature to the trigger temperature through manual operation, and it often exceeds the trigger temperature. Therefore, it is not easy for inspectors to judge whether the product quality of fire sprinklers meets the standards; second, during the inspection process, inspectors need to climb to a certain height to facilitate reaching the fire sprinklers. However, when the fire sprinklers are spraying water, the inspectors have no time to dodge. Even if other personnel are responsible for closing the valve, the remaining water in the water pipe will spray on the inspectors, affecting their subsequent work. Summary of the Invention

[0035] Optionally, a locking member is provided at the bottom of the battery assembly.

A locking ring 36 is threadedly connected to the threaded groove 35 of the connecting tube 3, and its upper portion is closely attached to the bottom of the annular housing 28. The locking ring 36 effectively limits the battery assembly to prevent it from falling off.

[0036] Optionally, the control mechanism includes a controller 37 provided on the support tube 1 , a screen 38 is provided on the surface of the controller 37 , and two groups of sliding buttons 39 are provided on the controller 37 below the screen 38 .

[0037] Optionally, a snap-fit flange 40 is provided on the limit plate 9 corresponding to the position of the limit hole 11. When the fire sprinkler mounting base fails to protrude from the bottom surface of the floor, the snap-fit flange 40 can be inserted into the hole groove of the floor and smoothly snap-fitted to the fire sprinkler mounting base.

[0038] Optionally, a handle 41 is sleeved on the outer wall of the support pipe 1 below the drain pipe 13. The handle 41 can improve the comfort of gripping, thereby improving the work efficiency of the inspector.

[0039] Before using the device, different heat sources can be selected. When a heating rod is selected, it can be inserted into the fixed tube 27 and connected to the charging and discharging port 30 of the rechargeable battery 29. The rechargeable battery 29 provides energy to the heating rod, and the heat is discharged into the waterproof cover 5 through the heat transfer tube 26 and the vent 42. Alternatively, a smoke generator can be used, which can be connected to the fixed tube 27 via a pipe.

[0040] The steps are as follows:

[0041] 1. Docking with fire sprinklers:

[0042] Insert the limiting plate 9 from the opening of the right side wall, and connect the limiting hole 11 to the mounting seat of the fire sprinkler. At this time, the positioning and limiting process of the fire sprinkler is completed.

[0043] 2. Semi-sealing and temperature adjustment of waterproof cover 5 and fire sprinkler:

[0044] Pressing the sliding button 39 on one side activates the two upward electric push rods 8 through the controller 37. The piston rods of the upward electric push rods 8 push the upper support plate 7 on the corresponding side, driving the waterproof cover 5 upward to cover the glass tube of the fire sprinkler. The corresponding temperature is memorized based on the color of the glass tube. As the heating rod gradually heats up, heat enters the curved section of the heat transfer tube 26 through the heating rod and is discharged outward through the various vents 42. Heat accumulates within the waterproof cover 5, gradually increasing its temperature. At this point, the temperature sensor 12 transmits a signal to the controller 37, and the detailed value is displayed on the screen 38, allowing testers to observe whether the glass tube of the fire sprinkler has exploded by the corresponding value, thereby determining whether the fire sprinkler meets product quality standards.

[0045] 3. Operation of the sealing and blocking mechanism between the waterproof cover 5 and the fire sprinkler:

[0046] Pressing the slide button 39 on the other side controls the movement of the transverse electric push rod 14 through the controller 37. The piston rod of the transverse electric push rod 14 extends outward and pushes to the outer end. At this time, the fixed block 15 penetrates the middle of the fire sprinkler's water tray bracket, and its sealing plug 17 is aligned with the fire sprinkler's plug position. Then, the two upward electric push rods 8 are activated, driving the transverse electric push rod 14 upward through the waterproof cover 5, so that the sealing plug 17 is continuously engaged with the fire sprinkler's plug. As the sealing plug 17 engages, the water pressure increases, causing water to flow into the extrusion hole 19 of the sealing plug 17 and out through the various diversion holes 21. The water comes into contact with the water-swelling rubber seals 22, causing them to continue to expand until they are firmly attached to the inner wall of the plug. The water barrier 23 prevents water from contacting the water-swelling rubber seals 22 from the outside of the sealing plug 17. The water flow generated during this process is effectively collected by the waterproof cover 5 to prevent it from being sprayed onto the tester. The water flows through the guide pipe 6 of the waterproof cover 5 into the connecting pipe 3 of the support cover 2 and converges in the support pipe 1. A water pipe or water bottle can be installed on the drain pipe 13 of the support pipe 1 to temporarily store this part of the water flow. It has a reasonable structural design and is easy to operate. There is no need to climb. Not only can the fire sprinkler inspection work be completed standing on the ground, which greatly facilitates the inspection work. At the same time, it can also effectively prevent the water sprayed by the fire sprinkler from splashing onto the body without affecting the subsequent work. In particular, the temperature is controllable and adjustable, and it is suitable for different types of fire sprinklers, making it easier for inspectors to determine whether the product quality meets the standards, solving the problems existing in the prior art.
