Abstract
Description
Technical Field
[0001] The invention relates to the field of fire-fighting equipment, in particular to a water permeability detection device for a fire-fighting sprinkler water supply pipeline. Background Art
[0002] The fire sprinkler system is an important part of modern building fire safety. When a fire occurs, the fire sprinkler water pipe can deliver water to the sprinkler head in time, and the sprinkler head sprays water in the form of mist or column, thereby effectively suppressing the spread of fire and buying precious time for personnel evacuation and fire fighting and rescue. Therefore, the water permeability of the fire sprinkler water pipe is directly related to whether the entire fire sprinkler system can function normally when a fire occurs.
[0003] At present, there are certain limitations in the detection method of water permeability of fire sprinkler water pipes. The traditional detection method is mainly to inject water into the water pipe and then observe whether there is water seepage at the pipe joints to determine whether there is a leak in the pipe. However, this method has some disadvantages.
[0004] Specifically, during the water injection test, since water flows relatively slowly and is colorless and transparent, when there is a small leak in the pipeline, the seeping water may not be easy to detect. Especially in some complex installation environments, such as when the pipeline is wrapped or installed in a relatively hidden location, it becomes more difficult to judge whether the pipeline is leaking by observing the water seepage with the naked eye, which is prone to misjudgment. Summary of the invention
[0005] The purpose of the present invention is to provide a fire sprinkler water pipe water permeability detection device to solve the problems raised in the above background technology.
[0006] To achieve the above object, the present invention provides the following technical solutions:

[0008] A detection box, wherein conveying grooves are provided above both sides of the detection box, a mounting bracket is fixed in the middle of the left side of the detection box, and the bracket is located below the conveying groove on the left side, and a water delivery valve is provided in the middle of the top of the detection box;
[0009] Rollers are movably arranged on both sides of the interior of the detection box and close to the bottom of the conveying trough, and clamping mechanisms are arranged on both ends of the interior of the detection box and close to the top of the rollers;
[0010] A flow guide cover is arranged at the lower part of the interior of the detection box, and a switching mechanism is arranged at the middle part of the bottom end of the flow guide cover;

[0012] A smoke generator is arranged on the right side of the upper end of the slide, a machine box is arranged on the left side of the top end of the slide, and a pumping mechanism is arranged between the machine box and the smoke generator.
[0013] In the present invention, the clamping mechanism includes a pressure roller, which is movably arranged just above the top of the roller, and electric push rods are arranged on both sides of the top of the detection box, and the output shaft of the electric push rod is connected to the roller.
[0014] In the present invention, guide rods are arranged on the upper ends of both sides of the pressing roller, and guide grooves movably sleeved with the guide rods are arranged on both sides of the upper end of the detection box and close to the electric push rod.
[0015] In the present invention, the switching mechanism includes a reversing valve, which is connected to the reversing valve at the lower middle part of the air guide cover, a discharge pipe is vertically arranged at the bottom end of the reversing valve, a spray pipe is horizontally arranged at the other end of the reversing valve, and a smoke sensor is arranged at the lower right side of the air guide cover.
[0016] In the present invention, the horizontal moving mechanism includes a mounting frame, which is arranged at the top right side of the platform, a screw rod is movably arranged between the detection box and the mounting frame, a motor is arranged on the back side of the mounting frame, the output shaft of the motor is fixedly connected to the screw rod, and the slide is threadedly connected to the screw rod.
[0017] In the present invention, a bottom frame is arranged at the bottom end of the slide, a plurality of rollers are movably arranged below the bottom frame, and a bottom groove matching the bottom frame is arranged at the top end of the platform.
[0018] In the present invention, the pumping mechanism includes an air compressor, which is arranged inside the chassis, one end of the air compressor passes through the chassis and is located on the left side of the chassis. A standard joint is arranged on the outside, and the other end of the air compressor is connected to the smoke generator through a suction pipe 1. A suction pipe 2 is installed in the middle of the suction pipe 1 through a tee, and the other end of the suction pipe 2 is connected to the lower right side of the detection box through a bellows.
[0019] In the present invention, an electric heating tube is arranged at the lower part of the smoke generator, an oil inlet is arranged at the upper right end of the smoke generator, and a temperature sensor and a liquid level sensor are arranged in sequence at the lower right side of the smoke generator.
[0020] Compared with the prior art, the present invention has the following beneficial effects:
[0021] 1. The present invention uses smoke with a dye for detection. In the smoke generator, the atomized oil is heated by the electric heating tube to generate colored smoke.

Compared with the colorless and transparent water in the traditional water injection detection, the colored smoke is easier to be found.
[0022] 2. The present invention uses smoke detection because smoke has better fluidity than water. When the air compressor pumps the smoke in the smoke generator into the water pipeline, the smoke can quickly fill the entire pipeline. In addition, during the detection process, there is no need to wait for the pipeline to be filled with water and the pressure to be stable like water injection detection, which greatly shortens the detection time.
[0023] 3. After the detection is completed, the cleaning liquid can be poured into the equipment through the water supply valve to clean the inside. The cleaning liquid flushes the guide cover and then passes through the reversing valve and is discharged from the discharge pipe. This cleaning method is relatively simple and convenient. Compared with the traditional method of manually cleaning the accumulated water in the pipeline after water injection detection, it reduces the consumption of manpower and time.

A standard joint 25 is arranged on the outside, and the other end of the air compressor 24 is connected to the smoke generator 7 through a suction pipe 1 26. A suction pipe 27 is installed in the middle of the suction pipe 1 26 through a tee, and the other end of the suction pipe 27 is connected to the lower right interior of the detection box 1 through a bellows; an electric heating pipe 28 is arranged at the lower inside of the smoke generator 7, an oil inlet 29 is arranged at the upper right end of the smoke generator 7, and a temperature sensor 30 and a liquid level sensor 31 are arranged in sequence at the lower right side of the smoke generator 7.
[0033] In this embodiment, smoke containing a dye is used for detection. In the smoke generator 7, the atomized oil is heated by the electric heating tube 28 to generate colored smoke. When this smoke is pumped into the water pipeline, if there is a leak in the pipeline, the colored smoke will overflow from the leak. Compared with the colorless and transparent water in traditional water injection detection, this colored smoke is easier to be found.
[0034] Preferably, smoke detection is used because smoke has better fluidity than water. When the air compressor 24 pumps the smoke in the smoke generator 7 into the water pipe, the smoke can quickly fill the entire pipe. In addition, during the detection process, there is no need to wait for the pipe to be filled with water and the pressure to stabilize as in water injection detection, which greatly shortens the detection time.
[0035] Furthermore, after the inspection is completed, cleaning liquid can be injected through the water supply valve 10 to clean the inside of the equipment. The cleaning liquid flushes the deflector 4 and passes through the reversing valve 15 and is discharged from the discharge pipe 16. This cleaning method is relatively simple and convenient. Compared with the traditional method of manually cleaning the accumulated water in the pipeline after water injection inspection, it reduces the consumption of manpower and time.
[0036] Working principle: During the inspection, one end of the water pipeline is inserted into the conveying groove 2 on the left and pushed forward until the end of the water pipeline is exposed from the conveying groove 2 on the right, and then assembled and connected with the standard joint 25. The other end of the water pipeline is blocked by the blocking plate, and then the electric push rods 12 on the left and right sides are started. The electric push rods 12 drive the pressure rollers 11 to descend and cooperate with the rollers 3 to clamp the two ends of the water pipeline. Then start the air compressor 24. The air compressor 24 extracts the smoke generated by the electric heating tube 28 inside the smoke generator 7, and pumps it into the water pipeline through the standard joint 25. In this way, the smoke is sealed inside the water pipeline. If there is a leak in the water pipeline, then Smoke will overflow from the leakage point, and the pigment will stain the leakage point. When the air compressor 24 draws suction, it also draws air inside the detection box 1 through the suction pipe 27, so the air will flow downward and enter the reversing valve 15, and then be sprayed out through the spray pipe 17. If there is smoke at this time, the smoke sensor 18 will detect it, indicating that there is a leak in the water pipeline. If there is no leak in the water pipeline, after the detection is completed, the water pipeline is removed and the reversing valve 15 is started. The reversing valve 15 connects the guide cover 4 to the discharge pipe 16, and then the cleaning liquid is poured into the water valve 10. The cleaning liquid rinses the guide cover 4 and then passes through the reversing valve 15 and is discharged from the discharge pipe 16.
[0037] It should be noted that the atomizing oil is made of environmentally friendly smoke-generating materials, such as food-grade atomizing oil (such as atomizing oil made from specially treated vegetable oil) mixed with harmless dyes. This atomizing oil can produce smoke-like gas after heating, and the dye can make the smoke colored, making it easier to observe leakage.
[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
