Description

Technical Field

[0001] The utility model relates to the field of fire protection, in particular to a fire protection smoke exhaust pipe airtightness detection device. Background Art

[0002] Firefighting means eliminating hidden dangers and preventing disasters (i.e. preventing and resolving man-made, natural and accidental disasters encountered by people in the process of life, work and study). Of course, its narrow meaning in the early stage of people's understanding is: extinguishing fire.

[0003] Most of the methods for tightness testing are to seal both ends of the pipe and then immerse the pipe in water to test its tightness. However, due to the large volume of the fire smoke exhaust pipe itself, a large amount of water and containers need to be prepared if the above method is used. After the test, the pipe will be taken out, which is easy to bring out a large amount of water, thereby easily causing a waste of water resources. In addition, due to the special locations that require bent pipes for connection, these shapes of pipes are inconvenient to test. Utility Model Content

[0004] The purpose of the utility model is to provide a fire smoke exhaust pipe tightness detection device in order to solve the above-mentioned problem.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A fire smoke exhaust pipe tightness detection device comprises a placement table, a mounting mechanism for fixing one end of the pipe is mounted on the upper end of the placement table, and a detection mechanism for detecting the pipe;

[0007] The detection mechanism includes a water tank, which is fixed at the upper end of one side of the placement table. An ultrasonic atomizer is installed inside the water tank. An L-shaped frame is provided on one side of the water tank, and the L-shaped frame is fixed to the placement table. A suction pump is installed on the upper end of the L-shaped frame. An air intake hopper is installed at the input end of the suction pump. A takeover device is rotatably connected to the output end of the suction pump. A telescopic hose is threadedly connected to the upper end of the takeover device. A connecting plate is fixed to the output end of the telescopic hose. Second locking bolts are provided at the four corners of the connecting plate.

[0008] Preferably: a water injection pipe is provided at the front end of the ultrasonic atomizer, and a cover is threadedly connected to the front end of the water injection pipe, and the air inlet hopper is a structure that is wide at the top and narrow at the bottom.

[0009] Preferably: a rubber layer is provided at the bottom of the connecting plate, and a through hole is provided in the middle of the connecting plate.

[0010] Preferably: the installation mechanism includes an upper extension frame, which is fixed at the upper end of the other side of the placement table. A screw is rotatably connected inside the upper extension frame, a motor is installed at the input end of the screw, a sliding block is threadedly connected to the outer periphery of the screw, a sealing plate is fixed at one end of the sliding block, and first locking bolts are provided at the four corners of the sealing plate.

[0011] Preferably, the sliding block is slidably connected to the upper extension frame.

[0012] Preferably: a rubber layer is provided at one end of the sealing plate.

[0013] The beneficial effect is that when this device is used to detect the tightness of the fire smoke exhaust pipe, one end of the pipe is first fixed and sealed by the installation mechanism, and then the other end of the pipe is fixed to the connecting plate by the second locking bolt. After the second locking bolt is tightened through the rubber layer at the bottom of the connecting plate, the connection between the pipe and the connecting plate can be sealed. At this time, the ultrasonic atomizer and the suction pump are started, the ultrasonic atomizer atomizes the water in the water tank, and the suction pump draws the atomized water vapor into the pipe through the telescopic hose. In this way, if the airtightness of the pipe is poor, water mist or water droplets will overflow. In this way, after the pipe is tested in this way, a lot of water resources will not be consumed, and an overly large container is not required. Through the retractable and soft characteristics of the telescopic hose, combined with the adjustment structure of the installation mechanism, the device can be applied to pipes of various shapes.

A sliding block 34 is threadedly connected to the outer periphery of the screw rod 32. The sliding block 34 is slidably connected to the upper extension frame 31, and a sealing plate 35 is fixed to one end of the sliding block 34. A rubber layer is provided at one end of the sealing plate 35, and first locking bolts 36 are provided at the four corners of the sealing plate 35; one end of the pipeline is fixed to the sealing plate 35 by four first locking bolts 36, and after tightening the first locking bolts 36, the connection between the pipeline and the sealing plate 35 can be sealed through the rubber layer at one end of the sealing plate 35, and through the threaded connection between the screw rod 32 and the sliding block 34 and the sliding connection between the sliding block 34 and the upper extension frame 31, when the motor 33 drives the screw rod 32 to rotate, the sliding block 34 can drive the sealing plate 35 to rise and fall, so that the device can be suitable for pipelines of most shapes.

[0027] In this embodiment, the detection mechanism 4 includes a water tank 41, which is fixed to the upper end of one side of the placement table 1, an ultrasonic atomizer 42 is installed inside the water tank 41, a water injection pipe is provided at the front end of the ultrasonic atomizer 42, and a cover is threadedly connected to the front end of the water injection pipe, an L-shaped frame 43 is provided on one side of the water tank 41, and the L-shaped frame 43 is fixed to the placement table 1, a suction pump 44 is installed on the upper end of the L-shaped frame 43, an air intake hopper 45 is installed at the input end of the suction pump 44, the air intake hopper 45 is a structure that is wide at the top and narrow at the bottom, the output end of the suction pump 44 is rotatably connected to a takeover device 46, the upper end of the takeover device 46 is threadedly connected to a telescopic hose 47, a connecting plate 48 is fixed to the output end of the telescopic hose 47, a rubber layer is provided at the bottom of the connecting plate 48, and a through hole is provided in the middle of the connecting plate 48, and the four corners of the connecting plate 48 are provided A second locking bolt 49 is provided; the other end of the pipeline is fixed to the connecting plate 48 through the second locking bolt 49, and the second locking bolt 49 is tightened through the rubber layer at the bottom of the connecting plate 48 to seal the connection between the pipeline and the connecting plate 48. At this time, the ultrasonic atomizer 42 and the suction pump 44 are started, the ultrasonic atomizer 42 atomizes the water in the water tank 41, and the suction pump 44 draws the atomized water vapor into the pipeline through the telescopic hose 47.

[0028] Working principle: When the device detects the fire smoke exhaust pipe, it first uses the threaded connection between the screw rod 32 and the sliding block 34 and the sliding connection between the sliding block 34 and the upper extension frame 31. When the motor 33 drives the screw rod 32 to rotate, the sliding block 34 can drive the sealing plate 35 to rise and fall. After the sealing plate 35 is adjusted, one end of the pipe is fixed to the sealing plate 35 through four first locking bolts 36. After tightening the first locking bolts 36, the rubber layer at one end of the sealing plate 35 can seal the connection between the pipe and the sealing plate 35. After one end of the pipe is fixed, the other end of the pipe is fixed to the connecting plate 48 through the second locking bolts 49. After the rubber layer at the bottom of 48 tightens the second locking bolt 49, the connection between the pipe and the connecting plate 48 can be sealed. At this time, the ultrasonic atomizer 42 and the suction pump 44 are started. The ultrasonic atomizer 42 atomizes the water in the water tank 41, and the suction pump 44 draws the atomized water vapor into the pipe through the telescopic hose 47. In this way, if the airtightness of the pipe is not good, water mist or water droplets will overflow. By testing the pipe in this way, a lot of water resources will not be consumed, and there is no need for an overly large container. The telescopic hose 47 is retractable and soft, and can cooperate with the adjustment structure of the mounting mechanism 3 to make the device suitable for pipes of various shapes.
