[0028] like Figure 1-4 As shown, a sensor arrangement structure for measuring impact force includes a transparent horizontal water accumulation pipe 1 and a transparent test short-circuit elbow 2. The transparent horizontal water accumulation pipe 1 is provided with multiple sections. The multiple sections of the transparent horizontal water accumulation pipe 1 are fixed at the ends by a fixed flange 101. One end of the transparent horizontal water accumulation pipe 1 forms a sleeve structure with the transparent test short-circuit elbow 2 through a slip-on flange 201, and the two can maintain relative movement.

[0029] Specific as Figure 1As shown, a tension pressure sensor 4 is arranged between the fixed flange 101 and the slip-on flange 201, and the tension pressure sensor 4 is fixed between the fixed flange 101 and the slip-on flange 201 through a connecting component 6; four tension pressure sensors 4 are arranged, and are evenly distributed around the outside of the transparent horizontal water accumulation pipe 1 and the transparent test short-circuit elbow 2; a group of S-type sensors are arranged at 0 o'clock, 3 o'clock, 6 o'clock, and 9 o'clock respectively, fully considering the load bearing capacity of the additional bending moment on the bottom of the horizontal pipe caused by the impact of the elbow, and the group of S-type sensors at the 6 o'clock direction uses a larger range, which is consistent with the load distribution data on the pipe cross section.

[0030] The connecting assembly 6 includes a first concave shell 601 and a second concave shell 602, the first concave shell 601 and the second concave shell 602 are buckled with each other and fixedly sleeved on the outer wall of the tension and pressure sensor 4;

[0031] Specific as Figure 1-2 As shown, one side of the second concave shell 602 is fixedly connected with a mounting nut 604; a through hole 610 is opened on one side of the first concave shell 601, and a mounting nut 604 is also arranged in the through hole 610, and the mounting nut 604 is fixed to the side wall of the tension and pressure sensor 4; that is, one mounting nut 604 is fixed on one side of the second concave shell 602, and one mounting nut 604 is fixed on the side wall of the tension and pressure sensor 4 by passing through the through hole 610; the mounting nut 604 is threadedly connected with a screw 5, one end of the screw 5 passes through the fixed flange 101 and the slip-on flange 201, and is locked on the fixed flange 101 and the slip-on flange 201 by the fixing nut 3.

[0032] A flange 7 is provided on one side of the slip-on flange 201, one end of the screw 5 passes through the flange 7, and the flange 7 is locked on one side of the slip-on flange 201 by the fixing nut 3. The flange 7 can increase the force uniformity of the flexible flange and facilitate assembly and disassembly.

[0033] Further, as Figure 1 , 3 As shown in FIG. 4 , the specific structure of the first concave shell 601 and the second concave shell 602 being mutually buckled is as follows: a fitting plate 608 is integrally connected to one end of the first concave shell 601, and a rectangular groove 605 is opened at one end of the second concave shell 602;

[0034] The fitting plate 608 is located inside the rectangular groove 605 . A through threaded hole 607 is provided inside the fitting plate 608 and the rectangular groove 605 . A threaded nail 603 is connected to the inner thread of the threaded hole 607 .

[0035] Furthermore, Figure 1 , 3As shown in , 4, a first magnet disk 606 is fixedly connected to one side of the fitting plate 608, and a second magnet disk 609 is fixedly connected to the inside of the rectangular groove 605. When the fitting plate 608 is located inside the rectangular groove 605, the first magnet disk 606 and the second magnet disk 609 attract each other due to their opposite poles. By means of the first magnet disk 606 and the second magnet disk 609, when the fitting plate 608 is located inside the rectangular groove 605, the first concave shell 601 and the second concave shell 602 can be temporarily fixed at the connection without loosening, so as to facilitate the installation of the threaded nail 603.

The load bearing capacity of the additional bending moment on the bottom of the horizontal pipeline due to the impact of the elbow is fully considered. The tension and pressure sensor 4 at the 6 o'clock direction is selected with a larger range, which is consistent with the load distribution data on the pipeline cross section. The pre-tightening force of the tension and pressure sensor 4 can be adjusted by the screw 5, the installation nut 604, and the fixing nut 3. By adding the split flange 7, the force uniformity of the flexible flange can be increased, and it is easy to assemble and disassemble;

[0038] Moreover, on the one hand, the screw rod 3 is directly connected to the tension and pressure sensor 4, and on the other hand, it is connected to the tension and pressure sensor 4 through the connecting assembly 6, so that the tension and pressure sensor 4 is easy to connect and install. When the transparent test short-circuit elbow 2 is subjected to impact force, the tension and pressure sensor 4 is subjected to tension, and the impact force of the slug flow can be tested, thereby verifying the test and recording data.
