[26] The pulling mechanism 8 includes guide sleeves 81, contact rods 82, fixed plates 83, first guide wire wheels 84, second guide wire wheels 85, connecting plates 86, pull wires 87, and elastic pieces 88. Six guide sleeves 81 are fixedly connected to the circumference of the middle part of the outer side of the framework body 4 at equal intervals, and the guide sleeves 81 correspond to the supporting plates 2; the contact rods 82 are slidably connected to the insides of the guide sleeves 81 in a penetrating manner; the contact rods 82 cooperate with the inclined blocks 74; the fixed plates 83 are fixedly connected to the top ends of the contact rods 82; each elastic piece 88 is connected between the bottom of each fixed plate 83 and the top of each guide sleeve 81; the elastic pieces 88 are sleeved on the contact rods 82; six groups of first guide wire wheels 84 are rotatably mounted at the circumference of the upper part of the outer side of the framework body 4 at equal intervals; two first guide wire wheels 84 form one group; twelve connecting plates 86 are fixedly connected to the circumference of the top of the framework body 4 at equal intervals; every two connecting plates 86 form one group; every two connecting plates 86 correspond to two first guide wire wheels 84 on each side; two second guide wire wheels 85 are rotatably connected between tail ends and two outer sides of the two connecting plates 86 on each side; the pull wires 87 are symmetrically connected to the inner end of the fixed plate 83; and the tail ends of the pull wires 87 bypass the first guide wire wheels 84 and the second guide wire wheels 85 and are fixedly connected to the lower parts of the inner side surfaces of the reset plates 6.

[27] Firstly, an operator pours a proper amount of water into the framework body 4, threads the tail end of a pipeline to the middle part of the fixed frame 41, moves it into the framework body 4 to contact water, and initiates the driving mechanism 7. When the driving mechanism 7 operates to contact the pulling mechanism 8, the driving mechanism 7 drives the pulling mechanism 8 to work; the pulling mechanism 8 operates to drive the reset plates 6 to swing upward; the reset plates 6 swing upward to push water; the driving mechanism 7 continues to operate to be separated from the pulling mechanism 8; the pulling mechanism 8 operates to be reset; and the reset plates 6 also swing downward to be reset, again and again. The water can be continuously pushed to fluctuate. The water fluctuation continuously impacts the pipeline, and the operator can know the influence of the water fluctuation on the pipeline. After the experiment on the influence of the water fluctuation on the pipeline is completed, the driving mechanism 7 is shut down, the pulling mechanism 8 stops working, the reset plates 6 stop swinging, and the pipeline is taken out of the fixed frame 41.

[28] When the tail end of the pipeline passes through the fixed frame 41 and contacts the water, the driving motor 71 is initiated; the driving motor 71 anticlockwise rotates to drive the transmission assembly 76 to anticlockwise rotate; the transmission assembly 76 anticlockwise rotates to drive the rotating shaft 75 to anticlockwise rotate; the rotating shaft 75 anticlockwise rotates to drive the disk 73 to anticlockwise rotate; and the disk 73 anticlockwise rotates to drive the inclined blocks 74 to anticlockwise rotate. When the inclined blocks 74 anticlockwise rotate to contact the pulling mechanism 8, the inclined blocks 74 drive the pulling mechanism 8 to operate, and the pulling mechanism 8 drives the reset plates 6 to swing upward. When the inclined blocks 74 continue to anticlockwise rotate to be separated from the pulling mechanism 8, the pulling mechanism 8 operates to be reset, and the reset plates 6 also swing downward to be reset. After the experiment on the influence of the water fluctuation on the pipeline is completed, the driving motor 71 is shut down, the disk 73 stops driving the inclined blocks 74 to anticlockwise rotate, and the inclined blocks 74 stop driving the pulling mechanism 8 to operate.

[29] When the driving motor 71 is initiated, and three inclined blocks 74 anticlockwise rotate to contact three of the contact rods 82, the inclined blocks 74 drive the contact rods 82 to move upward; the elastic pieces 88 extend; the contact rods 82 move upward to drive the fixed plate 83 to move upward; the fixed plate 83 move upward to drive the pull wires 87 to move upward; and the pull wires 87 move upward to drive, by means of the first guide wire wheels 84 and the second guide wire wheels 85, the reset plates 6 to swing upward; the reset plates 6 swing upward to push water to fluctuate. When the inclined blocks 74 continue to anticlockwise rotate to be separated from the contact rods 82, due to the action of the elastic pieces 88, the contact rods 82 move downward to drive the fixed plate 83 to move downward to be reset; the fixed plate 83 moves downward to be reset to drive the pull wires 87 to move downward to be loosened; and the reset plates 6 also swing downward to be reset, again and again. The water can be continuously pushed to fluctuate, and the water fluctuation impacts the pipeline. After the experiment on the influence of the water fluctuation on the pipeline is completed, the driving motor 71 is shut down, the inclined blocks 74 stop driving the contact rods 82 to move upward, and the reset plates 6 stop swinging.

[30] Referring to FIG. 1, FIG. 2, and FIG. 4, a circulating mechanism 9 is further included. The circulating mechanism 9 includes a cylinder 91, a piston rod 92, a one directional water pumping pipe 93, a one-directional water outlet pipe 94, and a filter net 95. The cylinder 91 is fixedly connected to the upper part of the inner side surface of each mounting frame 3; the middle of the bottom of the cylinder 91 is slidably connected with the piston rod 92 in a penetrating manner; the top end of the piston rod 92 is in sliding fit with the inside of the cylinder 91; the bottom end of the piston rod 92 isfixedly connected with the top of the fixed plate 83; the inner side of the bottom of the cylinder 91 is fixedly connected to and communicates with the one-directional water pumping pipe 93; the tail end of the one-directional water pumping pipe 93 runs through and communicates with the lower part of the framework body 4; the inner side of the bottom of the cylinder 91 is fixedly connected with and communicates with the one-directional water outlet pipe 94; the tail end of the one-directional water outlet pipe 94 runs through and communicates with the lower part of the framework body 4; and the circumference of the inner side of the tail end of the one-directional water pumping pipe 93 is fixedly connected with the filter net 95.

[31] An adjustment mechanism 10 is further included. The adjustment mechanism 10 includes a cross rod 101, a slotted circular ring 102, porous frameworks 103, n-shaped rods 104, first springs 105, baffle plates 106, and L-shaped rods 107. The cross rod 101 is fixedly connected to the top end of the rotating shaft 75; the slotted circular ring 102 is fixedly connected among the outer ends of the cross rod 101; the tail end of the one directional water outlet pipe 94 is fixedly connected with the porous frameworks 103; three n-shaped rods 104 are slidably connected to the inner sides of the tops of the porous frameworks 103 in a penetrating manner at equal intervals; the baffle plates 106 are fixedly connected between two ends of the bottoms of the n-shaped rods 104; the baffle plates 106 are in contact fit with the inner sides of the porous frameworks 103; two first springs 105 are connected between the inner tops of the n-shaped rods 104 and the outer tops of the porous frameworks 103; the middles of the inner sides of the upper parts of the n-shaped rods 104 are fixedly connected with the L-shaped rods 107; and the bottom ends of the L-shaped rods 107 are in contact fit with the top of the slotted circular ring 102.

[32] When the fixed plate 83 moves upward, the fixed plate 83 moves upward to also drive the piston rod 92 to move upward; the piston rod 92 moves upward to pump water in the framework body 4 into the cylinder 91 through the one-directional water pumping pipe 93; and the filter net 95 filters debris in the water. When the fixed plate 83 moves downward to be reset, the fixed plate 83 drives the piston rod 92 to move downward to be reset; the piston rod 92 moves downward to push the water in the cylinder 91 into the one-directional water outlet pipe 94; and the water in the one-directional water outlet pipe 94 is drained into the framework body 4, so that the water in the framework body 4 further fluctuates. When the fixed plate 83 stops moving, the piston rod 92 also stops moving, and the one-directional water pumping pipe 93 stops pumping the water into the cylinder 91. As such, the water in the framework body 4 greatly fluctuates to carry out a better impact experiment on the pipeline.

[33] When the driving motor 71 is initiated, the rotating shaft 75 anticlockwise rotates to also drive the cross rod 101 to anticlockwise rotate; the cross rod 101 anticlockwise rotates to drive the slotted circular ring 102 to anticlockwise rotate. Due to the action of the first springs 105, the slotted circular ring 102 anticlockwise rotates to drive the L shaped rods 107 to move up and down; the L-shaped rods 107 move up and down to drive the n-shaped rods 104 to move up and down; the n-shaped rods 104 move up and down to drive the baffle plates 106 to move up and down, so that when the water in the one directional water outlet pipe 94 is drained, the water is drained into the porous frameworks 103; the water in the porous frameworks 103 is continuously drained into the framework body 4; and since the baffle plates 106 continuously move up and down, the water in the porous frameworks 103 can be discharged intermittently. When the driving motor 71 is shut down, the rotating shaft 75 stops driving the slotted circular ring 102 to anticlockwise rotate, and the baffle plates 106 also stop moving up and down. As such, the water can be discharged intermittently to adjust the water amount.

[34] Referring to FIG. 1, FIG. 2, and FIG. 4, L-shaped plates 11, guide pipes 12, fastening bolts 13, and mounting sleeves 14 are further included. The L-shaped plates 11 are fixedly connected to the six inner sides of the fixed frame 41; the mounting sleeves 14 are fixedly connected between the inner ends of the six L-shaped plates 11; the guide pipes 12 are slidably connected into the mounting sleeves 14 in a penetrating manner; each fastening bolt 13 is connected to the front side of each mounting sleeve 14 through a thread in a penetrating manner; and the inner ends of the fastening bolts 13 are in contact fit with the guide pipes 12.

[35] Brush plates 15, second springs 16, and fixed blocks 17 are further included. Six fixed blocks 17 are fixedly connected to the circumference of the bottom of the slotted circular ring 102 at equal intervals, and each brush plate 15 is slidably placed on the outer side of the top of each fixed block 17; the brush plates 15 cooperate with the filter net 95; and two second springs 16 are connected between the bottoms of the brush plates 15 and the tops of the fixed blocks 17.

[36] Firstly, the operator twists the fastening bolt 13 to anticlockwise rotate and move outwards to be separated from the guide pipe 12, and then pulls the guide pipe 12 to move up and down. When the guide pipe 12 moves up and down to a suitable position, the guide pipe 12 is stopped being pulled to move up and down, and the fastening bolt 13 is twisted to move inward to contact the guide pipe 12 to fix the guide pipe. When the tail end of the pipeline passes through the middle of the fixed frame 41, the tail end of the pipeline passes through the mounting sleeve 14 and moves into the framework body 4 to be in contact with water. After the experiment on the influence of the water fluctuation on the pipeline is completed, the pipeline is taken out of the mounting sleeve 14. In this way, the pipeline can be placed better.

[37] When the slotted circular ring 102 anticlockwise rotates, the slotted circular ring 102 also drives the fixed block 17 to anticlockwise rotate, and the fixed block 17 anticlockwise rotates to drive the brush plate 15 to anticlockwise rotate. When a brush anticlockwise rotates to contact the filter net 95, the brush plate 15 removes debris on the filter net 95. Due to the action of the second spring 16, the brush plate 15 can be in close contact with the filter net 95. When the slotted circular ring 102 stops anticlockwise rotating, the fixed block 17 also stops driving the brush plate 15 to anticlockwise rotate. In this way, the phenomenon that the water cannot be drained into the one-directional water pumping pipe 93 because a large amount of debris remains on the filter net 95 can be avoided.
