[0019] As introduced in the background art, there are deficiencies in the prior art. To solve the above technical problems, the present application proposes a detection device for liquid fluidity and a method for detecting the performance of drag reducers. Embodiment 1

When the conversion piece 63 rotates forward, it drives the operation of the chamber air pressure adjustment component 61. When the conversion piece 63 rotates in the reverse direction, it drives the operation of the air pressure adjustment component 62 inside the tube; The fixing device 7 includes multiple groups of clamping members 71 and a lifting member 72 for controlling the operation of the clamping members 71. During the process of the lifting member 72 driving the placing table 2 to move upward, the clamping members 71 are driven to fix the liquid receiving beaker 4.

[0021] Specifically, pure liquid is placed in one of the liquid storage test tubes 5, and at the same time, the liquid mixed with the drag reducer is placed in another liquid storage test tube 5. The two liquid storage test tubes 5 are located in the transparent chamber 3, that is, in the same environment. Then, the liquid receiving beaker 4 for receiving the liquid is placed on the placing table 2. The lifting member 72 drives the liquid receiving beaker 4 to move upward and makes the beaker mouth of the liquid receiving beaker 4 close to the liquid outlet of the liquid storage test tube 5. Through the power transmission between the clamping member 71 and the lifting member 72, the clamping member 71 fixes the liquid receiving beaker 4. Then, the one-way valve at the bottom of the liquid storage test tube 5 is opened, and it is observed which liquid storage test tube 5 has all the liquid flowing into the liquid receiving beaker 4 first, and timing is carried out. After the first round of experiments, through the setting of the conversion member 63, the air pressure regulating assembly 61 of the chamber body is driven to operate, increasing the air pressure in the transparent chamber 3. Then, the fluidity detection is carried out, and it is observed which liquid storage test tube 5 has all the liquid flowing into the liquid receiving beaker 4 first after the air pressure is increased, and timing is carried out, so as to detect and analyze the performance of the drag reducer; Through the setting of the air pressure regulating assembly 61 of the chamber body, the air pressure in the transparent chamber 3 is adjusted, so that the device can detect and compare the performance of the drag reducer under different air pressure environments, solving the problem that the pressures in the mine shafts in different regions are different, and the effects produced by the drag reducer are different. Therefore, for the conventional detection methods of the performance of the drag reducer, the detection results cannot be applied to the use of liquids in various environments. Embodiment 2

One side of the sealing plate 611 is rotatably connected with a first reciprocating lead screw 612 through a bearing, and one side of the transparent chamber 3 is rotatably connected with a threaded sleeve 613 through a sealed bearing. The threaded sleeve 613 extends to the other side of the vertical plate 8, and the first reciprocating lead screw 612 is threadedly assembled in the threaded sleeve 613; The air pressure regulating component 62 inside the pipe includes a plurality of pistons 621. A moving plate 622 is provided at the top of the inner cavity of the transparent chamber 3. The top of the moving plate 622 is rotatably connected to a second reciprocating lead screw 623 through a bearing. The plurality of pistons 621 are fixedly installed at the bottom of the moving plate 622. The pistons 621 are fitted with the liquid storage test tubes 5. The top of the transparent chamber 3 is rotatably connected to a threaded collar 624 through a sealed bearing. The second reciprocating lead screw 623 is threadedly assembled inside the threaded collar 624; The conversion component 63 includes a transmission belt 631. A worm 632 is rotatably connected to the transparent chamber 3 through a bearing. An outer periphery of the threaded collar 624 is fixedly connected with a worm gear 633. The worm gear 633 is meshed and connected with the worm 632. One end of the worm 632 extends to one side of the vertical plate 8. Two belt pulleys 634 are arranged on one side of the vertical plate 8. One of the belt pulleys 634 is rotatably connected to the vertical plate 8 through a one-way bearing and is fixedly connected with one end of the worm 632. The other belt pulley 634 is installed on the outer periphery of the threaded sleeve 613 through a one-way bearing. The transmission belt 631 is sleeved on the two belt pulleys 634.

First, the performance of the drag reducer is detected under normal pressure. At this time, the pure liquid in the liquid supply chamber 9 flows into one of the liquid storage test tubes 5. The liquid supply chamber 9 and the reagent chamber 10 simultaneously flow the pure liquid and the drag reducer into the other liquid storage test tube 5. Then, the one-way valve at the bottom of the liquid storage test tube 5 is opened. By observing the liquid flow rates in the two liquid storage test tubes 5 and respectively calculating the time after the liquids in the two liquid storage test tubes 5 completely flow into the liquid receiving beaker 4, the performance of the drag reducer is detected; Secondly, the performance of the drag reducer is detected under the condition of increased air pressure.

Through the threaded connection between the first reciprocating lead screw 612 and the threaded sleeve 613, the first reciprocating lead screw 612 is driven to move forward, thereby driving the sealing plate 611 to move forward, and further increasing the pressure inside the transparent chamber 3. Then, the liquid flow rate in the liquid storage test tube 5 is detected and timed, and compared with the result of the previous group of liquid fluidity detection under normal pressure. At this time, due to the setting that the belt pulley 634 connected to the worm 632 is connected to the worm 632 through a one-way bearing, when the motor drives the two belt pulleys 634 to rotate simultaneously, one of the belt pulleys 634 drives the threaded sleeve 613 to rotate, and the other belt pulley 634 cannot drive the worm 632 to rotate; When the pressure suddenly increases during the detection of the liquid in the liquid storage test tube 5, the performance of the drag reducer is detected. By the reverse operation of the first motor 635, due to the setting that the threaded sleeve 613 and one of the pulleys 634 are connected through a one-way bearing, when the first motor 635 runs in reverse, one of the pulleys 634 cannot drive the threaded sleeve 613 to rotate, but can drive the worm 632 fixedly connected to the other pulley 634 to rotate. Through the meshing connection between the worm gear 633 and the worm 632, the worm gear 633 is driven to rotate, thereby driving the threaded collar 624 to rotate. Through the threaded connection between the threaded collar 624 and the second reciprocating lead screw 623, the second reciprocating lead screw 623 is driven to rotate, so that the moving plate 622 moves downward, and then drives all the pistons 621 into the liquid storage test tube 5, thereby increasing the air pressure in the liquid storage test tube 5, so as to detect and time the liquid flow rate in the liquid storage test tube 5, and compare it with the result of the previous group of liquid fluidity detection under normal pressure.
