Description

Technical Field

[0001] The invention belongs to the technical field of pipeline nondestructive testing, and in particular relates to a fire protection pipeline nondestructive testing device. Background Art

[0002] When the fire pump station supplies water to a building, it needs to first pass through the underground fire water supply pipeline, and then pass through the basement of the building to the fire water supply port in the building for fire emergency use;

[0003] The fire-fighting pipes in the basement are all wrapped with a protective layer on the outside, and the damage of the fire-fighting pipes cannot be directly observed from the outside. This is especially true for underground fire-fighting pipes. When encountering geological conditions such as subsidence, the pipes are prone to cracks and other damage. At present, there are few means of detecting such hidden fire-fighting pipes. The only way is to destroy the ground or peel off the protective layer to detect from the outside of the pipe. The project is large in volume, difficult to detect, and prone to inaccurate detection, which increases the difficulty of fire-fighting pipe detection;

[0004] Existing detection technologies include close-interval potential method, potential gradient method, AC current attenuation method, ultrasonic detection method and magnetic flux leakage detection method, among which ultrasonic detection technology uses the characteristics of ultrasonic waves that propagate at a uniform speed and can be partially reflected on the metal surface to perform pipeline flaw detection. At present, when inspecting the inside of metal welded iron pipes, the inside of the pipes is slippery and prone to sliding, which causes the detection area to shift, making it difficult to monitor and adjust the detection area, resulting in low detection efficiency and reduced device use effect.

[0037] The linkage assembly 4 is provided with a dirt scraping assembly 5, which includes a sleeve 1 501, an electric push rod 2 502, a connecting pin 503, a telescopic rod 504, a spring 2 505, a sleeve 2 506 and a scraper 507. The surface of the sleeve 405 is fixed with sleeves 1 501 arranged symmetrically, the interior of the sleeve 1 501 is fixed with an electric push rod 2 502, the output end of the electric push rod 2 502 is fixed with a connecting pin 503, the connecting pin 503 slides inside the sleeve 1 501, a scraper 507 is provided at one end of the connecting pin 503, the surface of the scraper 507 is fixed with a sleeve 2 506, the sleeve 2 506 slides on the surface of the connecting pin 503, and a spring 2 505 is fixed between the connecting pin 503 and the sleeve 2 506;

[0038] A telescopic rod 504 is fixed between the second sleeve 506 and the connecting pin 503 , and a second spring 505 is wound around the surface of the telescopic rod 504 .

[0039] In this embodiment, when the fire protection pipeline nondestructive testing device is used, the moving block 312 is first pushed to move to one end of the limit slide rod 311, and then the adjusting screw 314 is rotated according to the diameter of the pipeline, thereby driving the frame 313 to move, and the frame 313 is moved, and the electromagnet 315 is driven to move synchronously, so that the distance between the two groups of electromagnets 315 matches the internal diameter of the pipeline. Through this operation, the electromagnet 315 can be adsorbed on the surface of pipelines with different diameters, thereby improving the flexibility and practicality of the device;

[0040] Then, the moving block 1 312 is pushed to approach the square block 310, and then the electromagnet 2 316 and the electromagnet 3 317 are energized, and the generated magnetic force is mutually attracted to fix the electromagnet 1 315 at the initial stage, so that during the movement of the device in the later stage, the electromagnet 1 315 does not contact the inner wall of the pipe, thereby reducing friction and improving the smoothness of the movement of the device;

[0041] Then, the detection device is placed inside the pipeline, and the nondestructive testing instrument 2 is moved by the moving mechanism 1. The moving mechanism is a prior art and is not within the scope of innovation. Moreover, the moving mechanism has an adjustment function and is suitable for different diameters. When the device moves to the pipeline nondestructive testing area, the driving motor 322 is started, thereby driving the spur gear mechanism 403 to rotate, and the spur gear mechanism 403 drives the guide rod 402 to rotate, and the guide rod 402 drives the bevel gear mechanism 401 to rotate, and then the bevel gear mechanism 401 drives the ratchet 407 to rotate. Since the ratchet 407 is meshed with the pawl 408, the pawl 408 is connected to the connecting disk 406, thereby driving the connecting disk 406 to rotate, and the connecting disk 406 drives the bevel gear The second mechanism 409 rotates, and along with the rotation of the bevel gear mechanism 409, the two groups of reciprocating screw rods 320 are driven to rotate. Since the reciprocating screw rods 320 and the second moving block 318 are threadedly connected, the two groups of moving blocks 318 are driven to move away from each other, and the moving block 312 is pushed to move by the second moving block 318, and the moving block 312 drives the frame 313 to move, and the frame 313 drives the electromagnet 1 315 to move until the electromagnet 1 315 contacts the inner wall of the pipe, and then the electromagnet 1 315 is energized, and the electromagnet 1 315 generates magnetism, so that it is adsorbed on the inner surface of the pipe, and then the electromagnet 2 316 and the electromagnet 3 317 are de-energized, so that the magnetism between the electromagnet 2 316 and the electromagnet 3 317 is lost;

[0042] Then, the inspection area is inspected by the nondestructive testing instrument 2. During the inspection, the laser rangefinder 307 is turned on at the same time, and the plug rod 303 is started to shrink, and the silicone ball 306 is driven to move downward, so that the silicone ball 306 is separated from the inner wall of the sleeve 304, thereby releasing the connection between the plug rod 303 and the sleeve 304. The setting of the silicone ball 306 can play a protective buffering effect, and at the same time increase the friction force, improve the stability of the connection between the plug rod 303 and the sleeve 304, and when the moving mechanism 1 slides When the rod 303 moves in the sleeve 304, the rod 303 is designed in a cone-shaped structure, so that when the sleeve 304 and the rod 303 move away from each other, the contact is reduced, and a certain friction is reduced, and at the same time, it is convenient for the rod 303 to be better inserted into the sleeve 304 later, and the use effect of the device is further improved. At this time, the distance from the laser rangefinder 307 to the rod 303 changes, and the data signal is sent to the external display screen for display, and the detection is carried out in real time. When the distance changes, the movement is then started. The moving mechanism 1 moves and is adjusted in real time through the original spacing. When the insertion rod 303 contacts the baffle 309, the baffle 309 compresses the spring 308. This process can play a distance buffering effect, avoiding the moving mechanism 1 from moving a large distance, causing the electromagnet 315 to move and affecting the distance change, thereby better improving the stability of the adsorption of the electromagnet 315 and further improving the use effect of the device. Through the above operation, it can be ensured that the detection area is always within the preset range, thereby ensuring the accuracy and reliability of the detection result, avoiding deviations in the detection area due to the movement of the equipment, which may misjudge the pipeline condition and cause unnecessary maintenance or replacement. Real-time monitoring can detect and correct this situation in time, and real-time monitoring can reduce this repetitive work, thereby shortening the time required for the entire detection process. Accurate detection results can help maintenance personnel to detect and solve pipeline problems in time and prevent accidents, thereby improving the overall safety of the pipeline system, improving detection efficiency, and improving the use effect of the device to meet actual use needs.

[0043] Before inspecting the pipeline, the electric push rod 2 502 is started, which in turn drives the connecting pin 503 to move, and the scraper 507 is driven to contact the inner wall of the pipeline through the connecting pin 503. The setting of the spring 2 505 can play a buffering effect when the scraper 507 contacts the pipeline to avoid deformation of the scraper 507 caused by a large thrust. At the same time, the telescopic rod 504 can increase the connection stability between its sleeve 2 506 and the connecting pin 503. At the same time, the moving mechanism 1 is started to drive the scraper 507 to move, and the stains inside the pipeline are scraped off by the scraper 507. At the same time, the reverse rotation is started, and the guide rod 402 is driven to rotate through the spur gear mechanism 403. At this time, when the bevel gear mechanism 1 401 rotates, it also drives the ratchet 407 to rotate, so that the ratchet 408 is on the ratchet 407. The bevel gear mechanism 409 is in a stationary state at the same time, along with the guide rod 402, it can drive the bevel gear mechanism 404 to rotate, and the bevel gear mechanism 404 drives the casing 405 to rotate, and the casing 405 drives the casing 1 501 and the scraper 507 to rotate synchronously, so as to rotate the scraper 507 at an angle, so that the inner wall of the pipeline can be scraped in all directions. By cleaning, these interference factors can be removed, making the detection result more accurate, avoiding the possible impact of a large amount of sediment or other substances on the operation of the detection equipment, so that by cleaning the pipeline, this risk can be reduced, ensuring the safety of the detection process, and at the same time, it can also avoid stains from interfering with the normal operation of the electromagnet 1 315, further improving the adsorption effect of the electromagnet 1 315, and improving the use effect of the device.

[0044] By setting the linkage component 4, the forward and reverse rotation of the drive motor 322 can meet the different time period requirements of the two processes with the cooperation of the linkage component 4, which can reduce the number of equipment operations, thereby reducing energy consumption and maintenance costs.

[0045] When the nondestructive testing instrument 2 completes the inspection, the electromagnet 1 315 is powered off to release the adsorption of the pipeline, and then the electromagnet 2 316 and the electromagnet 3 317 are powered on to generate magnetic force for mutual adsorption. As the moving block 2 318 moves, the moving block 1 312 can be driven to move, so that the moving block 1 312 drives the electromagnet 1 315 to move through the frame 313, so that the electromagnet 1 315 is separated from the inner wall of the pipeline, thereby not affecting the movement effect of the moving mechanism 1 in the pipeline, and improving the use effect of the device.
