DETAILED DESCRIPTION

[0016] In order to make the technical means, creative features, purposes and effects realized by the present application easy to understand, the present application is further described below in combination with specific embodiments.

[0017] As shown in the figure, the present application provides the following technical solutions: Figures 1-6 Embodiment one: a building decoration new material quality detection device, comprising a detection box 1 and a cabinet door 2 hinged at the open end of the detection box 1, a partition plate 11 fixedly connected in the middle of the detection box 1, a support plate 3 installed at the inner bottom end of one side of the detection box 1, a round convex block 30 fixedly connected to one side wall of the support plate 3, a support plate 31 in L shape fixedly connected to the other side wall of the support plate 3, an air cylinder 32 installed at the inner end of the support plate 31, and the output end of the air cylinder 32 located at one side of the round convex block 30, an expansion air bag 33 sleeved on the outer arc surface of the round convex block 30, an air pump one 34 installed on the outer wall of the support plate 3, a sliding plate 4 slidingly connected at the front end of the inner bottom of the detection box 1, a semicircular ring 42 installed on one side wall of the sliding plate 4, a half expansion air bag 43 fixedly connected to the inner end of the semicircular ring 42, an air pump two 44 installed on the other side wall of the sliding plate 4, an I-shaped groove 101 formed at the inner bottom end of the detection box 1 near the edge, a plurality of fixing holes 102 formed at the inner bottom end of the I-shaped groove 101, a slide bar fixedly connected to the bottom end of the sliding plate 4, and bolts 41 threadedly connected at both ends of the slide bar and extending into the fixing holes 102, self-locking universal wheels 16 installed at the bottom end of the detection box 1, an air pipe one connected to the inner end of the expansion air bag 33 arranged at the output end of the air pump one 34, and an air pipe two connected to the inner end of the half expansion air bag 43 arranged at the output end of the air pump two 44.

[0018] ​In use, according to the length of the pipeline to be detected, loosen the bolt 41 at the bottom end of the sliding plate 4, adjust the position of the sliding plate 4 along the I-shaped groove 101 in the detection box 1, so that the distance between the support plate 3 and the sliding plate 4 is adapted to the length of the pipeline, and after the adjustment is completed, the bolt 41 is tightened into the corresponding fixed hole 102 to realize the fixation of the sliding plate 4. Then open the cabinet door 2, put one end of the straight pipe to be detected on the expanded air bag 33 outside the round convex block 30, and the other end is aligned with the half-expanded air bag 43 of the sliding plate 4. Start the air pump one 34 and the air pump two 44, inflate the expanded air bag 33 and the half-expanded air bag 43 through the air pipe one and the air pipe two respectively, and after inflation, the two expand to realize stable clamping and positioning of the bent pipe from both ends and the inner side of the pipeline, avoid displacement of the pipeline during detection, and the self-locking universal wheel 16 can conveniently move the device to a suitable position and can be locked at any time.

[0019] Example two: The technical solution of this embodiment is different from that of example one, which comprises a diaphragm constant temperature storage box 14 installed at the angle in the detection box 1, a hot air assembly one 110 installed at the bottom end of the partition plate 11 near the pipe angle, and a hot air assembly two 15 embedded at the bottom end of the detection box 1 near the pipe angle.

[0020] In use, first complete the length adaptation, position adjustment and stable clamping of the pipeline to be detected according to the operation steps of example one. If the detection needs to be matched with functional film materials (such as photosensitive film), the film materials are put into the diaphragm constant temperature storage box 14 at the angle in the detection box 1 in advance, the performance of the film materials is kept stable through the constant temperature environment, and the influence of temperature and humidity changes on the detection result is avoided. According to the detection requirements, start the hot air assembly one 110 at the bottom end of the partition plate 11 and the hot air assembly two 15 at the bottom end of the detection box 1 to blow hot air of appropriate temperature to the periphery of the pipeline, so as to preheat the surface of the pipeline and improve the bonding effect of the film materials and the pipeline.

[0021] Example three: The technical solution of this embodiment is different from that of example one, which comprises a ball joint base 320 fixedly connected to the output end of the air cylinder 32, a universal ball 321 ball-joint connected to the ball joint base 320, a plurality of universal joints 35 arranged on one side of the universal ball 321, a fixed shaft 36 fixedly connected between adjacent two universal joints 35, a light source disc 37 sleeved on the outer wall of the fixed shaft 36, a light source lamp 38 extending to the outer end embedded on the outer wall of the light source disc 37, and a pipeline support wheel assembly 360 mounted on the outer wall of the fixed shaft 36. The pipeline support wheel assembly 360 comprises support wheels, a plurality of supporting arms, compression springs, fixed seats, and a hinge structure between the supporting arms. A storage drawer 12 is slidably connected to the upper end of the detection box 1, and the storage drawer 12 and the side wall of the cabinet door 2 are respectively embedded with a transparent observation window one 13 and a transparent observation window two 21.

[0022] Among them, air pump 1 34, air pump 2 44, hot air assembly 1 110, hot air assembly 2 15 (if activated) and cylinder 32 are all centrally controlled by the controller set at the top of the test box 1, which can start and stop with one button, adjust the inflation pressure, hot air temperature and cylinder 32 extension and retraction speed, making the operation convenient and efficient. The light source disk 37 integrates a high-precision drive circuit board. This circuit board is electrically connected to each of the light source lamps embedded in the outer wall of the light source disk through wires. It can precisely control the start and stop, brightness and emission frequency of the light source lamps to ensure stable output of LED blue light source (wavelength 450-500nm).

[0023] When in use, adjust and fix the position of the sliding plate 4 according to the length of the pipe to be tested (PVC light-transmitting bent pipe), align the two ends of the pipe with the expansion airbag 33 and the semi-expansion airbag 43 respectively, start the air pump 34 and the air pump 44, inflate the airbag through the air tube, and the inflated airbag will be firmly clamped from the inside of both ends of the pipe to prevent the detection from shifting.

[0024] If it is necessary to detect pipeline defects by "inner light transmission + outer photosensitive color change", first process the photosensitive film application: Select a reversible photochromic polymer film (substrate is PET, thickness is 50μm, under 450-500nm blue light irradiation, it changes from colorless to dark blue within 10 seconds, and returns to colorless within 30 seconds after irradiation stops, and can be reused). Cut it into 2-3 arc-shaped film pieces according to the bending curvature of the pipeline. After pre-folding to match the curvature, apply it from the bending point to both ends. Start the hot air components one and two, and at the same time use a soft scraper to smooth it from the inside to the outside, expel air to eliminate wrinkles, and ensure that the film material is tightly bonded to the pipe wall without gaps.

[0025] Then, cylinder 32 is activated, and its output end is connected to the ball joint 321 via ball joint seat 320, driving the detection assembly composed of multiple universal joints 35 and fixed shaft 36 to extend into the pipeline. The support arm of the pipeline support wheel assembly 360 is elastically extended and retracted by compression springs and flexibly adjusted in angle by hinge structure, so that the support wheel always fits against the inner wall of the pipeline (including bending areas), ensuring that the assembly moves smoothly along the pipeline trajectory. At the same time, the high-uniformity LED blue light source (wavelength 450-500nm, low attenuation rate when penetrating PVC pipe, and can clearly distinguish defects from the pipe body) of the light source disk 37 on the outer wall of the fixed shaft 36 is turned on. The blue light emitted by the light source lamp 38 penetrates the pipe wall evenly. If there are defects such as microcracks or holes in the pipeline, the defect area will change the light propagation path, causing the photosensitive film on the outside of the pipe to show differentiated light-colored spots or striped areas.

[0026] Workers can visually observe the color change pattern of the photosensitive film through the transparent observation window 13 of storage drawer 12 and the transparent observation window 21 of cabinet door 2, and infer the location and size of defects. Storage drawer 12 can store spare photosensitive films or testing tools, and the self-locking casters 16 facilitate moving the device to a suitable testing position. After testing, the light source and cylinder are turned off, the gas in the airbag is released, the photosensitive film is removed (it will return to colorless within 30 seconds for backup or disposal), and the pipe can then be taken out.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by the present invention.
