[0020] The present invention is further described below through specific embodiments in conjunction with the accompanying drawings, but the present invention is not limited thereto. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

[0021] Example 1

[0022] A pressure pipeline detection device described in this embodiment, such as Figure 1 As shown, it includes a fixing ring 1, and a channel communicating with the inside and outside is opened on one side of the fixing ring 1. The overall structure is "C"-shaped, which is convenient for directly fitting on the pressure pipe, thereby reducing cumbersome installation steps, reducing the difficulty of the inspection personnel's work and improving the inspection efficiency;

[0023] The outer ring surface of the fixing ring 1 is provided with a through groove communicating with the inside and outside, and at least two guide rods 3 are independently installed in the through groove, so that the guide rods 3 can move along the fixing ring 1 in the through groove, thereby flexibly adjusting the positions of the guide rods 3 and the clamping plate 7, making it more convenient for the inspection personnel to operate, and avoiding the inability to conduct effective inspection due to the special installation position of individual pressure pipes;

[0024] The guide rods 3 located inside the fixing ring 1 are all provided with clamping plates 7, and the clamping plates 7 are clamped together. The guide rods 3 located outside the fixing ring 1 are provided with limiting components for fixing them on the fixing ring 1, so as to facilitate adjustment and clamping of pressure pipes with different diameters, thereby improving the applicability and increasing the fixing effect, making the pressure sensor 5 more stable when detecting the pressure pipe, and making its detection data more accurate and more referenceable;

[0025] The pressure sensor 5 is a prior art, and is usually composed of a pressure sensitive element, a device for converting the force or motion generated by the pressure sensitive element into an electrical parameter, and a device for displaying or recording the electrical parameter. In actual use, a piezoresistive pressure sensor is used;

[0026] The resistance strain gauge is one of the main components of the piezoresistive strain sensor. The working principle of the metal resistance strain gauge is that the resistance value of the strain resistor adsorbed on the base material changes with mechanical deformation, which is commonly known as the resistance strain effect.

[0027] A pressure sensor 5 for detecting the pressure pipeline is arranged on the fixing ring 1 between the guide rods 3, and a connecting component is arranged between the pressure sensor 5 and the fixing ring 1. The connecting component is used to adjust the position of the pressure sensor 5 on the fixing ring 1, which is convenient for adjusting the position of the pressure sensor 5 left and right according to the change of the diameter of the detected pressure pipeline so that it always fits the detected pressure pipeline, and it is also convenient to adjust the contact point between the pressure sensor 5 and the pressure pipeline during the detection process, so that multi-point detection can be performed on each area of ​​the pressure pipeline, making its detection data more accurate, and it is also convenient to compare through multiple groups of detection data, so as to more clearly and accurately reflect the situation of the pressure pipeline, and reduce the more serious consequences caused by the deviation of the detection point affecting the judgment of the actual situation of the pressure pipeline.

[0028] The limit assembly includes an adjustment block 2, which is sleeved on the guide rod 3 located outside the fixing ring 1 and threadedly matched therewith, and the width of the through groove is smaller than the diameter of the adjustment block 2, so that the position of the guide rod 3 can be fixed by the adjustment block 2 after the clamping plate 7 is fitted with the pressure pipe, so that the clamping plate 7 and the pressure pipe are closely fitted to complete the clamping and fixing, avoiding displacement or even falling off during the detection process to affect the detection data;

[0029] The guide rods 3 between the clamping plate 7 and the fixing ring 1 are all sleeved with springs 4, which not only improves the convenience during installation and removal, but also reduces the wear of the clamping plate 7 and the fixing ring 1 and increases their service life.

[0030] like Figure 1 , Figure 3 and Figure 4 As shown, the connection assembly includes a fixed tube 9, which is independently installed in the through groove. Slide blocks 10 are arranged on the left and right side walls of the fixed tube 9. The inner side wall of the through groove is provided with a slide groove for the slide block 10 to move in a circular motion on the fixed ring 1. The pressure sensor 5 located outside the fixed ring 1 is provided with a second limit block 6 threadedly matched therewith, and the width of the through groove is smaller than the diameter of the second limit block 6, so that the fixed ring 1 is fixed to the pressure pipe through the clamping plate 7, and then the pressure sensor 5 slides on the fixed ring 1, so as to perform multi-point detection on the pressure pipe, and then improve the accuracy of the detection data by comparing multiple sets of data;

[0031] The sliding block 10 is in a spherical structure at the sliding groove portion, so as to improve the smoothness and stability during sliding.

[0032] A connecting assembly is provided between the guide rod 3 and the fixing ring 1, and the connecting assembly includes a fixing tube 9, which is independently installed in the through groove. A second sliding block is provided on the left and right side walls of the fixing tube 9, so as to increase the stability of the guide rod 3 and the clamping plate 7 when they are moved left and right for adjustment, so as to achieve a better clamping and fixing effect, and at the same time facilitate a more comprehensive inspection of the pressure pipeline.

[0033] The clamping plate 7 is in an arc-shaped structure, and the outer ends of the clamping plate 7 and the fixing ring 1 are rounded, which is convenient for increasing the fit with the pressure pipe, making it have a better clamping effect, and is convenient for preventing the fixing ring 1 and the clamping plate 7 from scratching the pressure pipe during installation, which affects the use strength;

[0034] The contact surface between the clamping plate 7 and the pressure pipe is provided with an anti-skid layer, which is convenient for reducing the wear between the clamping plate 7 and the pressure pipe and for increasing the fit between the clamping plate 7 and the pressure pipe when the guide rod 3 rotates.

[0035] When the clamp 7 fits tightly against the fixing ring 1, the distance between the ends of the clamp 7 is the same as the distance between the ends of the fixing ring 1, which makes it easy to determine the maximum usable pipe diameter through the opening between the ends of the fixing ring 1. When in use, any pressure pipe that can pass through the opening of the fixing ring 1 can be clamped and fixed by the clamp 7, thereby to a certain extent.

[0036] like Figure 2 As shown, the guide rod 3 and the clamping plate 7 are connected by a bearing, and a mounting groove for mounting the bearing is provided on the clamping plate 7. The outer ring of the bearing is fixed to the wall of the mounting groove, and the inner ring is fixed to the guide rod 3, so that when the guide rod 3 is rotated, the clamping plate 7 does not rotate with it, so that the clamping plate 7 is always in contact with the pressure pipe, thereby increasing the fixing effect and the difficulty of adjustment;

[0037] When a connecting assembly is also provided between the guide rod 3 and the fixing ring 1 , the guide rod 3 and the clamping plate 7 must be connected via a bearing.

[0038] Example 2

[0039] This embodiment further illustrates the technology. Figure 2 As shown, the limit assembly includes an adjusting block 2 and a first limit block 8. The adjusting block 2 is sleeved on the guide rod 3 located above and is threadedly matched therewith. The first limit block 8 is fixed on the guide rod 3 located below, and the guide rod 3 between the fixing ring 1 and the clamping plate 7 is sleeved with a spring 4. When in use, the position of the fixing ring 1 can be adjusted by adjusting the upper adjusting block 2 and then pulling the fixing ring 1 up and down, thereby improving the convenience during adjustment and allowing one person to complete the installation and position adjustment more easily and quickly. When in use, first loosen the adjusting block 2, and then pull the fixing ring 1 to create a gap between the clamping plate 7 on one side and the pressure pipe.

[0040] Working principle: first shrink the splint 7 to make it fit with the fixing ring 1, then put the fixing ring 1 on the pressure pipe, then adjust the adjusting block 2 and the guide rod 3 to make the splint 7 fit and fix with the pressure pipe, then rotate the pressure sensor 5 to make it fit with the pressure pipe and fix it through the second limit block 6 for detection, after one point detection is completed, loosen the fit between the second limit block 6 and the fixing ring 1, toggle the pressure sensor 5 to slide up and down on the fixing ring 1 to adjust the position of the pressure sensor 5 and fix it through the second limit block 6, so as to detect different positions; when it is necessary to adjust the position of the splint 7, first loosen the adjusting block 2 of the upper guide rod 3, then rotate the fixing ring 1, and then pull the fixing ring 1 to create a gap between the splint 7 below and the pressure pipe, slide the splint 7 on the fixing ring 1 to adjust the clamping position of the pressure pipe, and then rotate the fixing ring 1, and repeat this process until the splint 7 is adjusted to a suitable clamping point.
