Description

Technical Field

[0001] This utility model relates to the field of fire equipment testing technology, and more specifically, to non-destructive testing of fire equipment. Background Technology

[0002] Firefighting equipment refers to various devices and tools used for fire prevention, fire extinguishing, and rescue and escape operations at fire scenes. Common firefighting equipment includes fire extinguishers, fire hydrants, and fire hoses. Fire hoses are key equipment for transporting water during firefighting. If there are any damages, holes, or cracks, water will leak from these defects when high-pressure water flows through, resulting in insufficient water reaching the fire scene and making it impossible to effectively control and extinguish the fire, thus affecting the overall effectiveness of firefighting operations. Therefore, it is necessary to thoroughly and meticulously inspect fire hoses for damage, holes, and cracks.

[0003] A search revealed that Chinese patent CN220309661U discloses a leak detection device for fire-fighting equipment. The device comprises a fire hose, ball bearings, a fixing plate, and a water tank. The ball bearings support and guide the fire hose, making its movement smoother. Leaks are detected by immersing the fire hose in a water-filled tank. The device has a simple structure, requires minimal space, and is easy and quick to operate.

[0004] When the above-mentioned detection device is in use, it can detect whether the fire hose is leaking. However, for some very minor leaks, because the water is in a relatively static state in the water storage tank, the bubbles are small and rise slowly. Under the interference of the water background in the water storage tank, it is difficult to accurately detect them with the naked eye. Therefore, it cannot be detected in time. Minor leaks may gradually expand during the actual use of the fire hose. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides non-destructive testing equipment for fire protection, which aims to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a non-destructive testing fire-fighting equipment, including a storage box and two infrared thermal imagers, with the two infrared thermal imagers fixedly installed on the front and rear sides of the storage box. The storage box has a horizontal plate inside, and a limiting assembly is provided on the top of the horizontal plate. The limiting assembly includes a limiting frame, multiple lead screws, multiple pressing plates, and multiple rotary handles. The bottom end of the limiting frame is fixedly connected to the horizontal plate. One end of each of the multiple lead screws is fixedly connected to one of the multiple pressing plates, and all the lead screws are threadedly connected to the limiting frame. One end of each of the multiple rotary handles is fixedly connected to one of the multiple lead screws. The number of limiting assemblies is two.

[0007] Furthermore, a gasket is fixedly connected to one side of each of the plurality of extrusion plates, wherein the gasket can serve as a buffer.

[0008] Furthermore, a hydraulic cylinder is fixedly connected to the center of the bottom end of the horizontal plate, and the bottom end of the hydraulic cylinder is fixedly connected to the storage box.

[0009] As can be seen, the above technical solution facilitates the adjustment of the positions of multiple extrusion plates.

[0010] Furthermore, side panels are fixedly connected to the bottom edges of both sides of the storage box.

[0011] As can be seen, in the above technical solution, the two side plates are fixed with bolts to prevent the storage box from moving during testing.

[0012] Furthermore, a side frame is fixedly connected to one side of the storage box, and a moving component is provided on the side frame. The moving component includes two uprights, two connecting plates, two rotating shafts, a stepper motor, and two gears.

[0013] Furthermore, both connecting plates are movably connected to the side frame via bearings, and both connecting plates are fixed to the two uprights via bolts. The bottom end of the stepper motor is fixedly connected to one of the gears, and the two gears are respectively fixedly sleeved on the two rotating shafts, and the two gears mesh with each other.

[0014] It can be seen that the above technical solution is designed to facilitate the horizontal movement of the fire hose.

[0015] Furthermore, a fixed frame is fixedly connected to the top of the side frame, and the stepper motor is fixedly installed on the top of the fixed frame.

[0016] It can be seen that the above technical solution is designed to facilitate the support of the stepper motor.

[0017] The technical effects and advantages of this utility model are as follows:

[0018] 1. This utility model uses two infrared thermal imagers to detect the outer side of the fire hose. The piston rod on the hydraulic cylinder extends and moves the horizontal plate upward, thereby moving the two limit brackets upward. Rotating the handle causes the lead screw to rotate and move, thereby moving the extrusion plate. Similarly, the position of other extrusion plates is adjusted. The fire hose is limited by multiple extrusion plates. The operation is simple, the detection range is wide, and the use effect is good.

[0019] 2. This utility model involves passing a fire hose through two upright poles, then starting a stepper motor. The stepper motor drives one of the rotating shafts to rotate. Since two gears mesh, one rotating shaft can drive the other rotating shaft to rotate, thereby driving the two connecting plates and the two upright poles to rotate. The fire hose can then be moved horizontally via the two upright poles. The structure is simple and easy to use. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] Refer to the instruction manual appendix Figure 1-5 The non-destructive testing fire-fighting equipment of this embodiment includes a storage box 1 and two infrared thermal imagers 2. The two infrared thermal imagers 2 are fixedly installed on the front and rear sides of the inside of the storage box 1. The storage box 1 is provided with a horizontal plate 8. The top of the horizontal plate 8 is provided with a limiting component 3. The limiting component 3 includes a limiting frame 301, multiple lead screws 302, multiple extrusion plates 303 and multiple handles 304. The bottom end of the limiting frame 301 is fixedly connected to the horizontal plate 8. One end of each of the multiple lead screws 302 is fixedly connected to the multiple extrusion plates 303, and the multiple lead screws 302 are all threadedly connected to the limiting frame 301. One end of each of the multiple handles 304 is fixedly connected to the multiple lead screws 302, and the number of limiting components 3 is two.

[0029] Furthermore, a gasket is fixedly connected to one side of each of the multiple extrusion plates 303. The gasket can play a buffering role. A hydraulic cylinder 9 is fixedly connected to the center of the bottom end of the horizontal plate 8, and the bottom end of the hydraulic cylinder 9 is fixedly connected to the storage box 1.

[0030] Furthermore, side panels 7 are fixedly connected to the bottom edges of both sides of the storage box 1.

[0031] Furthermore, a side frame 4 is fixedly connected to one side of the storage box 1. A movable component 5 is provided on the side frame 4. The movable component 5 includes two uprights 501, two connecting plates 502, two rotating shafts 503, a stepper motor 504, and two gears 505. The two connecting plates 502 are movably connected to the side frame 4 through bearings, and the two connecting plates 502 are fixed to the two uprights 501 through bolts. The bottom end of the stepper motor 504 is fixedly connected to one of the gears 505. The two gears 505 are respectively fixedly sleeved on the two rotating shafts 503, and the two gears 505 mesh with each other. A fixed frame 6 is fixedly connected to the top of the side frame 4, and the stepper motor 504 is fixedly installed on the top of the fixed frame 6.

[0032] The two side plates 7 are fixed with bolts to prevent the storage box 1 from moving during testing. The fire hose is passed through the two uprights 501, and then the stepper motor 504 is started. The stepper motor 504 drives one of the rotating shafts 503 to rotate. Since the two gears 505 are meshed, one of the rotating shafts 503 can drive the other rotating shaft 503 to rotate, thereby driving the two connecting plates 502 and the two uprights 501 to rotate. The fire hose can be moved horizontally through the two uprights 501. The structure is simple and easy to use. The fixing between the uprights 501 and the connecting plates 502 can be released by bolts. The uprights 501 of different diameters can be replaced according to the diameter of the fire hose.

[0033] The usage method of this embodiment is as follows:

[0034] In use, the fire hose is threaded into the storage box 1, and then hot water at a certain temperature, such as 30-40℃, is introduced into the fire hose to raise its temperature and distribute it evenly. Two infrared thermal imagers 2 are used to detect the outside of the fire hose. Due to minor leaks, water will seep out, causing the local temperature to differ from other parts. This will be displayed as an abnormal temperature area on the infrared thermal image. Based on the color distribution and temperature differences in the thermal image, the operator can determine whether there are minor leaks and their location. The hydraulic cylinder 9 is then activated, and the piston rod on the hydraulic cylinder 9 extends, causing the horizontal plate 8 to move upward, thereby causing the two limit frames 301 to move upward. The handle 304 is rotated, causing the lead screw 302 to rotate and move, thereby causing the extrusion plate 303 to rotate and move. Similarly, the positions of the other extrusion plates 303 are adjusted, and the piston rod on the hydraulic cylinder 9 retracts, causing multiple extrusion plates 303 to move downward. Finally, the fire hose is threaded through the two limit frames 301, and the multiple extrusion plates 303 limit the fire hose. The operation is simple, the detection range is wide, and the effect is good.
