[0075] The detailed features and advantages of the embodiments of the present application are described in detail in the embodiments below, and the contents are sufficient to enable any person skilled in the art to understand the technical content of the embodiments of the present application and to implement the embodiments of the present application. According to the contents, claims and drawings disclosed in the present specification, any person skilled in the art can easily understand the purposes and advantages related to the present application. The following embodiments are further detailed to illustrate the present application, but do not limit the scope of the present application in any way.

[0076] Please refer to Figures 1 to 4 . Figure 1 is a side view of the pipeline pressure sensing device and the pipeline to be measured according to the first embodiment of the present application. Figure 2 is Figure 1 a side view of the pipeline pressure sensing device and the pipeline to be measured in Figure 3 is Figure 1 a top view of the pipeline pressure sensing device and the pipeline to be measured in Figure 4 is Figure 3 a cross-sectional view of the pipeline pressure sensing device and the pipeline to be measured in

[0077] In the present embodiment, the pipeline pressure sensing device 10 is used to be arranged on a pipeline to be measured 20 and includes, for example, a first magnetic seat 100, a second magnetic seat 200, two mounting assemblies 300 and a load cell 400. The pipeline to be measured 20 is made of a material that can be attracted by a magnet, such as metal. The pipeline pressure sensing device 10 and the pipeline to be measured 20 can form a pipeline assembly (not numbered). The pipeline pressure sensing device 10 is arranged on the outer surface 21 of the pipeline to be measured 20 and is a non-invasive pipeline pressure sensing device. That is, the pipeline pressure sensing device 10 can be arranged on the outer surface 21 of the pipeline to be measured 20 without breaking the pipeline to be measured 20.

[0078] In the present embodiment, the first magnetic base 100 includes, for example, a base body 110, a magnet set 120, and a knob 130. The magnet set 120 is disposed in the base body 110. The knob 130 protrudes from one side of the base body 110 and is used to control the magnetic field generated by the magnet set 120. The second magnetic base 200 includes, for example, a base body 210, a magnet set 220, and a knob 230. The magnet set 220 is disposed in the base body 210. The knob 230 protrudes from one side of the base body 210 and is used to control the magnetic field generated by the magnet set 220.

[0079] In addition, in the present embodiment, the first magnetic base 100 and the second magnetic base 200 are arranged along an axial direction A of the pipe 20 to be measured. The base body 110 has one or more first mounting surfaces 111, and the base body 210 has one or more second mounting surfaces 211. The first mounting surfaces 111 and the second mounting surfaces 211 are, for example, flat and are used to be mounted on the outer surface 21 of the pipe 20 to be measured. The number of the first mounting surfaces 111 can be two, and a gap 114 can be formed between the two first mounting surfaces 111 to facilitate the mounting of the first mounting surfaces 111 on the outer surface 21 of the pipe 20 to be measured. The second mounting surfaces 211 are the same, and thus are not described again. When the knobs 130, 230 are turned, the magnetic field generated by the magnet sets 120, 220 can be changed, thereby enabling the first magnetic base 100 and the second magnetic base 200 to be tightly attached to or detached from the outer surface 21 of the pipe 20 to be measured by the adsorption of the magnet sets 120, 220 to the pipe 20 to be measured.

[0080] In the present embodiment, each of the two mounting assemblies 300 includes, for example, a first fastener 310, a collet 320, a second fastener 325, and a universal joint 330. In each of the two mounting assemblies 300, the opposite ends of the collet 320 are fastened to the first fastener 310 and the second fastener 325, respectively, and the opposite ends of the second fastener 325 are fixed to the collet 320 and the universal joint 330, respectively. The first fastener 310 and the second fastener 325 are, for example, screws.

[0081] The load cell 400 comprises a housing 410 and a strain gauge 420 disposed in the housing 410. The opposite sides of the housing 410 are movably connected to the seat body 110 of the first magnetic seat 100 and the seat body 210 of the second magnetic seat 200 by two mounting assemblies 300. In detail, two first fasteners 310 are screwed into two screw holes 411 on the opposite sides of the housing 410, respectively. Two collets 320 are movably disposed in the seat body 110 of the first magnetic seat 100 and the seat body 210 of the second magnetic seat 200 by two second fasteners 325 and two universal joints 330, respectively. One end of the universal joint 330 is screwed into a screw hole 112 of the seat body 110 and a screw hole 212 of the seat body 210, respectively. With the assistance of the collets 320, the housing 410 can be more quickly disassembled from the seat bodies 110, 210. Moreover, with the assistance of the universal joints 330, the housing 410 can be installed at a desired angle on the seat bodies 110, 210 so that the load cell 400 can be disposed on the pipeline 20 of various sizes without causing distortion. In other embodiments, the universal joint and the collet can be one-piece. The load cell 400 further comprises a circuit device (not shown), for example. The strain gauge 420 is electrically connected to the circuit device. The circuit device can convert the deformation value of the pipeline 20 measured by the strain gauge 420 into a force.

[0082] It should be noted that in the present embodiment, the two mounting assemblies 300 are disposed on the top sides of the seat bodies 110, 210 away from the pipeline 20, but this is not limited thereto. In other embodiments, the mounting assemblies can be disposed on the side edges adjacent to the top sides of the seat bodies according to the forms of the first magnetic seat and the second magnetic seat.

[0083] Since the opposite sides of the load cell 400 are connected to the first magnetic seat 100 and the second magnetic seat 200, respectively, the load cell 400 can sense the force of the pipeline 20. In this way, not only can the measurement operation be conveniently performed by the magnetic attraction, but also the exact pressure value can be obtained through the force of the pipeline 20, thereby accurately judging the condition of the pipeline 20. In detail, please refer to Figure 5 , Figure 5 The test results of the pipeline pressure correction test using the pipeline pressure sensing device in Figure 3 In Figure 5 , the horizontal axis represents the pressure of the pipeline 20, and the vertical axis represents the signal generated by the load cell 400. Through the linear relationship between the pressure of the pipeline 20 and the signal generated by the load cell 400 presented by the correction line C in Figure 5 , the exact pressure value of the pipeline 20 can be obtained from the signal of the load cell 400 in application. Of course, the correction line C presented in Figure 5 is not limited.

[0084] Referring to Figures 6 to 8 , Figure 6 is a side view of the pipeline pressure sensing device and the pipeline to be measured according to the second embodiment of the present application. Figure 7 is Figure 6 is a top view of the pipeline pressure sensing device and the pipeline to be measured according to the second embodiment of the present application. Figure 8 is Figure 7 is a sectional view of the pipeline pressure sensing device and the pipeline to be measured according to the second embodiment of the present application.

[0085] In the present embodiment, the pipeline pressure sensing device 10a is used to be arranged on a pipeline to be measured 20a and comprises, for example, a plurality of first magnetic seats 100a, a plurality of second magnetic seats 200a, two mounting assemblies 300 and a load cell 400. The pipeline to be measured 20a is made of a material that can be attracted by a magnet, such as metal. The pipeline pressure sensing device 10a and the pipeline to be measured 20a can constitute, for example, a pipeline assembly (not numbered).

[0086] In the present embodiment, the first magnetic seat 100a comprises, for example, a seat body 110a, a Halbach array magnet 120a and a quick-release structure 130a. The Halbach array magnet 120a is arranged in the seat body 110a. The quick-release structure 130a is, for example, a screw and is screwed on one side of the seat body 110a to push against the outer surface 21a of the pipeline to be measured 20a. The second magnetic seat 200a comprises, for example, a seat body 210a, a Halbach array magnet 220a and a quick-release structure 230a. The Halbach array magnet 220a is arranged in the seat body 210a. The quick-release structure 230a is, for example, a screw and is screwed on one side of the seat body 210a to push against the outer surface 21a of the pipeline to be measured 20a. In the present embodiment, since the first magnetic seat 100a and the second magnetic seat 200a respectively comprise the Halbach array magnets 120a, 220a, the overall volume of the first magnetic seat 100a and the second magnetic seat 200a can be reduced while the first magnetic seat 100a and the second magnetic seat 200a generate sufficient magnetic force to be stably arranged on the outer surface 21a of the pipeline to be measured 20a. In this way, even if the installation space near the pipeline to be measured 20a is limited, the first magnetic seat 100a and the second magnetic seat 200a can still conveniently perform measurement operations.

[0087] Furthermore, in the present embodiment, the seat 110a has a first mounting surface 111a and a first anti-slip structure 113a, and the seat 210a has a second mounting surface 211a and a second anti-slip structure 213a. The first mounting surface 111a and the second mounting surface 211a are, for example, in the shape of a circular arc. The first anti-slip structure 113a is located on the first mounting surface 111a and is used to contact the outer surface 21a of the pipe 20a to be measured. The second anti-slip structure 213a is located on the second mounting surface 211a and is used to contact the outer surface 21a of the pipe 20a to be measured. The first anti-slip structure 113a and the second anti-slip structure 213a are, for example, also in the shape of a circular arc. Of course, in other embodiments, the first mounting surface and the second mounting surface can also be in any shape other than flat and circular arc. The first anti-slip structure 113a and the second anti-slip structure 213a can be a high-friction surface layer that the seat 110a and the seat 210a have themselves, or can be a friction-increasing element such as sandpaper attached to the surface of the seat 110a and the seat 210a.

[0088] The detailed structure of the mounting assembly 300 and the load cell 400 is the same as the corresponding elements in the first embodiment, and therefore will not be described again.

[0089] In the present embodiment, the first magnetic seats 100a are arranged along a circumferential direction P of the pipe 20a to be measured and are fixed to each other, for example, by a plurality of fasteners 150a. The second magnetic seats 200a are arranged along the circumferential direction P of the pipe 20a to be measured and are fixed to each other, for example, by a plurality of fasteners 250a. The fasteners 150a, 250a can be, for example, screws and are screwed into the seats 110a, 210a, respectively. The first magnetic seats 100a and the second magnetic seats 200a are arranged along an axial direction A of the pipe 20a to be measured. The opposite sides of the load cell 400 are connected to one of the first magnetic seats 100a and one of the second magnetic seats 200a, respectively, by two mounting assemblies 300.

[0090] Please refer to Figure 9 , Figure 9The difference between the second embodiment and the third embodiment is only the structure of the mounting assembly. The mounting assembly of the third embodiment comprises a force lever amplification mechanism. In detail, in the third embodiment, the pipeline pressure sensing device 10b is arranged on the outer surface 21a of the pipeline 20a and comprises one or more first magnetic seats 100a, one or more second magnetic seats 200a, two mounting assemblies 300b, and a load cell 400. In the third embodiment, each of the two mounting assemblies 300b comprises a first fastener 350b, a connecting rod 360b, a chuck 365b, a second fastener 366b, a first universal joint 370b, and a second universal joint 380b. The two first fasteners 350b are respectively fastened to the opposite sides of the housing 410. The opposite ends of the chuck 365b are respectively fixed to the first fastener 350b and the second fastener 366b. The opposite ends of the second fastener 366b are respectively fixed to the chuck 365b and the first universal joint 370b. The first fastener 350b and the second fastener 366b are, for example, screws. The two connecting rods 360b are pivotally connected to each other and each has a first assembly end 361b and a second assembly end 362b opposite to each other. The two first assembly ends 361b are movably arranged at one end of the two second fasteners 366b away from the housing 410 through the two first universal joints 370b. The two second assembly ends 362b are movably arranged on the seat body 110a of the first magnetic seat 100a and the seat body 210a of the second magnetic seat 200a through the two second universal joints 380b. The distance D1 from the pivot point B to the first assembly end 361b (i.e. the distance between the pivot point B and the connection between the first assembly end 361b and the first universal joint 370b) of the two connecting rods 360b is less than the distance D2 from the pivot point B to the second assembly end 362b (i.e. the distance between the pivot point B and the connection between the second assembly end 362b and the second universal joint 380b), so that the force transmitted from the first magnetic seat 100a and the second magnetic seat 200a to the load cell 400 through the mounting assembly 300b is amplified, so that the load cell 400 can more easily sense the pressure of the pipeline 20a. In the third embodiment, the connecting rod 360b is, for example, in the form of a rod, but is not limited thereto. In other embodiments, the connecting rod can also be replaced by a pivoted plate.

Figure 11 is Figure 10Fig. 6 is a sectional view of the pipe pressure sensing device and the pipe to be measured along the cutting surface line 11-11 in Fig. 5. The difference between the pipe pressure sensing device 10c of the present embodiment and the pipe pressure sensing device 10a of the second embodiment is only in the arrangement of the magnetic seats.

[0092] In the present embodiment, the pipe pressure sensing device 10c is arranged on the outer surface 21a of a pipe to be measured 20a and includes, for example, a plurality of first magnetic seats 100c, a plurality of second magnetic seats 200c, two mounting members 300, and a load cell 400. The pipe pressure sensing device 10c and the pipe to be measured 20a can constitute, for example, a pipe assembly (not shown).

[0093] The first magnetic seats 100c and the second magnetic seats 200c are similar in structure to the first magnetic seats 100a and the second magnetic seats 200a of the second embodiment, respectively, and thus will not be described again.

[0094] In the present embodiment, the first magnetic seats 100c are arranged in the axial direction A of the pipe to be measured 20a and are fixed to each other by, for example, a plurality of fasteners 150a. The second magnetic seats 200c are arranged in the axial direction A of the pipe to be measured 20a and are fixed to each other by, for example, a plurality of fasteners 250a. The first magnetic seats 100c and the second magnetic seats 200c are arranged in the circumferential direction P of the pipe to be measured 20a. The opposite sides of the housing 410 are connected to one of the first magnetic seats 100c and one of the second magnetic seats 200c by the two mounting members 300, respectively.

[0096] In the present embodiment, the pipe pressure sensing device 10d is arranged on the outer surface 21a of a pipe to be measured 20a and includes, for example, a plurality of first magnetic seats 100d, a plurality of second magnetic seats 200d, two mounting members 300, and a load cell 400. The pipe pressure sensing device 10d and the pipe to be measured 20a can constitute, for example, a pipe assembly (not shown).

[0097] The first magnetic seats 100d and the second magnetic seats 200d are similar in structure to the first magnetic seats 100a and the second magnetic seats 200a of the second embodiment, respectively, and thus will not be described again.

[0098] In this embodiment, the first magnetic seats 100d are arranged along the axial direction A of the pipe 20a to be measured and are fixed to each other, for example, by a plurality of fasteners 150a.

[0099] Referring to Figure 15 and Figure 16 . Figure 15 Fig. 6 is a side view of a pipe pressure sensing device and a pipe to be measured according to a sixth embodiment of the present application. Figure 16 Fig. 7 is a cross-sectional view of the pipe pressure sensing device and the pipe to be measured in Figure 15 . The difference between the pipe pressure sensing device 10e of the present embodiment and the pipe pressure sensing device 10 of the first embodiment is that the pipe pressure sensing device 10e of the present embodiment further comprises a positioning housing 500e. The positioning housing 500e is fixed to the seat body 110 of the first magnetic seat 100 and the seat body 210 of the second magnetic seat 200. For example, the positioning housing 500e can comprise a first plate portion 510e and a second plate portion 520e. The first plate portion 510e is connected to one side of the second plate portion 520e, and the first plate portion 510e and the second plate portion 520e are, for example, perpendicular to each other. That is, the first plate portion 510e and the second plate portion 520e, for example, jointly present an L shape. In addition, the first plate portion 510e can be fixed to the seat bodies 110, 210 by one or more fasteners 530e. The fasteners 530e are, for example, screws. The positioning housing 500e can position the seat bodies 110, 210 together to facilitate installation of the pipe pressure sensing device 10e.

[0100] The pipe pressure sensing device disclosed in the above embodiments can sense the force of the pipe to be measured by the load cell, because the opposite sides of the load cell housing are connected to the first magnetic seat and the second magnetic seat, respectively. In this way, not only can the measurement operation be facilitated by the magnetic attraction method, but also the exact pressure value can be obtained by the force of the pipe to be measured, so as to accurately judge the condition of the pipe to be measured.
