[0027] The following will be further described with reference to the drawings and specific embodiments:

[0028] Embodiment 1

[0029] AsFigure 1 , Figure 2 As shown in Figure 2 , a performance testing device for liquid sand suspension in fracturing includes a cup body 1. The cup body 1 is made of glass and has an open upper end, which facilitates the staff to clean the cup body 1 and pour out the sand, avoiding the influence of the presence of sand on the accuracy of the next monitoring. At the same time, scale lines 11 are provided on the side wall of the cup body 1, and the upper end of the scale lines 11 is set as the maximum scale value 12. When the staff takes out the sand-mixed liquid from the sand mixer truck, stirs it evenly in the sampling cup, and then pours it into the cup body 1, the liquid level in the cup body 1 is flush with the maximum scale value 12. The staff observes the sedimentation of the sand in the cup body 1 through the cup body 1, and at the same time uses a timer to time, and obtains the sedimentation speed of the sand by using two physical parameters of distance and time, so as to judge the performance of the liquid sand suspension. Of course, when only testing the performance of the liquid sand suspension through the cup body 1, the staff needs to stare at the cup body 1 for a long time and be in a state of nervous tension, with a large labor intensity.

[0030] As Figure 4 , Figure 5 , Figure 7 As shown in Figure 4 , Figure 5 , Figure 7 , in order to reduce the labor intensity of the staff, an industrial camera 5 and a computer 51 can be provided on the side of the cup body 1, and a bottom plate 4 is provided below the cup body 1. The cup body 1 is placed on one end of the bottom plate 4. At the same time, a vertical rod 41 is provided at the other end of the cup body 1, and an arc-shaped groove 42 is provided on the vertical rod 41. The industrial camera 5 is arranged facing the cup body 1. A sleeve 53 is provided on the side of the industrial camera 5. A limiting column 52 is provided on the hole wall of the sleeve 53, and a bolt is threaded through. The sleeve 53 is sleeved on the vertical rod 41, and the end of the bolt presses against the vertical rod 41. Under the action of the bolt, the sleeve 53 and the industrial camera 5 can be stably at a certain height. With the cooperation of the limiting column 52 and the arc-shaped groove 42, it can be ensured that the industrial camera 5 faces the cup body 1. The industrial camera 5 is electrically connected to the computer 51, and the industrial camera 5 monitors the cup body 1 in real time, sends the monitoring information to the computer 51, and compares it with the information pre-stored in the computer 51 to judge the sedimentation state of the sand in the cup body 1. For example, when the sand is completely sedimented, the sedimentation speed of the sand is obtained by using two physical parameters of distance and time, and the performance of the liquid sand suspension is obtained. In this way, the current situation of long-term manual observation is changed, the work intensity is reduced, and the monitoring accuracy is improved, because, compared with manual observation, the equipment is more rigorous.

[0031] As Figure 4As shown in the figure, in order to stably set the cup body 1 on the bottom plate 4, two snap chutes 44 are symmetrically arranged on the bottom plate 4. A bidirectional screw 43 is penetrated through the two snap chutes 44. A bottom plate 4 is arranged below the cup body 1. The lower end of the pressing plate 45 is fixedly provided with a snap slider 46. The snap slider 46 is located in the snap chute 44 and is threadedly sleeved on the bidirectional screw 43. The two pressing plates 45 clamp the bottom of the cup body 1. By rotating the bidirectional screw 43, the two pressing plates 45 can be controlled to approach or move away from each other, which facilitates clamping the cup body 1 by the two pressing plates 45 to place it stably or releasing the restriction on the cup body 1.

[0032] As Figure 4 , Figure 8 , Figure 9 shown, on the bottom plate 4 and outside the vertical rod 41, a support frame 6 is arranged. The support frame 6 includes an annular plate 61, a placement plate 63 and multiple support rods 62. The placement plate 63 and the annular plate 61 are respectively arranged at the upper and lower ends of the multiple support rods 62. The annular plate 61 is connected to the bottom plate 4 by bolts. A mixing cup 3 is inserted on the placement plate 63. The upper end of the mixing cup 3 is set to be open, and a cover plate is threadedly sleeved. Above the cover plate, there is a motor, and below there is a stirrer 32. The stirrer 32 is connected to the output shaft of the motor and is located in the mixing cup 3. The lower end of the mixing cup 3 is provided with an output pipe 31. A valve body is arranged at the junction of the output pipe 31 and the mixing cup 3. The output pipe 31 can extend into the cup body 1. The sand mixing liquid taken out by the staff is poured into the mixing cup 3. After the cover plate is threadedly sleeved on the mixing cup 3, the stirrer 32 is rotated by the motor to fully stir and mix the sand mixing liquid. Then the valve body is opened to make the sand mixing liquid flow out from the lower end of the output pipe 31 and flow into the cup body 1 until the liquid level in the cup body 1 is flush with the maximum scale value 12. In order to ensure that the sand mixing liquid flows into the cup body 1, the mixing cup 3 is located above the cup body 1.

[0033] As Figure 2 , Figure 3 shown, in order to reduce the influence of the liquid flowing in the cup body 1 on the sedimentation of the sand due to the liquid being stirred, a sealing cover 2 is threadedly sleeved at the opening of the cup body 1. A first adjusting screw 21 is threadedly penetrated through the middle of the sealing cover 2. The lower end of the first adjusting screw 21 is provided with a lifting disc 22. A sealing gasket 23 is arranged on the lifting disc 22. The sealing gasket 23 is in sliding contact with the side wall of the cup body 1. After the liquid level is flush with the maximum scale value 12, the sealing cover 2 is threadedly sleeved on the cup body 1, and the first adjusting screw 21 is rotated to adjust the height of the lifting disc 22 so that the lower side surface of the lifting disc 22 is flush with the maximum scale value 12 to limit the stirring of the liquid.

[0034] Example 2

[0035] As Figure 1 , Figure 2As shown in the figure, a performance testing device for liquid sand suspension in fracturing includes a cup body 1. The cup body 1 is made of glass and has an open upper end, which facilitates the staff to clean the cup body 1 and pour out the sand, avoiding the influence of the sand on the accuracy of the next monitoring. At the same time, scale lines 11 are provided on the side wall of the cup body 1, and the upper end of the scale lines 11 is set as the maximum scale value 12. When the staff takes out the sand-mixed liquid from the sand mixer truck, stirs it evenly in the sampling cup, and then pours it into the cup body 1, the liquid level in the cup body 1 is flush with the maximum scale value 12. The staff observes the sedimentation of the sand in the cup body 1 through the cup body 1, and at the same time uses a timer to time, and obtains the sedimentation velocity of the sand based on the two physical parameters of distance and time, so as to judge the performance of the liquid sand suspension. Of course, when only testing the performance of the liquid sand suspension through the cup body 1, the staff needs to stare at the cup body 1 for a long time and be in a state of nervous tension, with a large labor intensity.

[0036] As Figure 4 , Figure 5 , Figure 7 As shown in the figure, in order to reduce the labor intensity of the staff, an industrial camera 5 and a computer 51 can be set on the side of the cup body 1. A bottom plate 4 is provided below the cup body 1. The cup body 1 is placed on one end of the bottom plate 4. At the same time, a vertical rod 41 is provided at the other end of the cup body 1, and an arc-shaped groove 42 is provided on the vertical rod 41. The industrial camera 5 is arranged facing the cup body 1. A sleeve 53 is provided on the side of the industrial camera 5. A limiting post 52 is provided on the inner wall of the sleeve 53, and a bolt is threaded through. The sleeve 53 is sleeved on the vertical rod 41, and the end of the bolt presses against the vertical rod 41. Under the action of the bolt, the sleeve 53 and the industrial camera 5 can be stably at a certain height. With the cooperation of the limiting post 52 and the arc-shaped groove 42, it can be ensured that the industrial camera 5 faces the cup body 1. The industrial camera 5 is electrically connected to the computer 51, and the industrial camera 5 monitors the cup body 1 in real time, sends the monitoring information to the computer 51, and compares it with the information pre-stored in the computer 51 to judge the sedimentation state of the sand in the cup body 1. For example, when the sand is completely sedimented, the sedimentation velocity of the sand is obtained based on the two physical parameters of distance and time, and the performance of the liquid sand suspension is obtained. In this way, the current situation of long-term manual observation is changed, the work intensity is reduced, and the monitoring accuracy is improved, because the equipment is more rigorous compared with manual observation.

[0037] As Figure 4As shown in the figure, in order to stably set the cup body 1 on the bottom plate 4, two snap chutes 44 are symmetrically arranged on the bottom plate 4. A bidirectional screw 43 is arranged through the two snap chutes 44. A bottom plate 4 is arranged below the cup body 1. The lower end of the extrusion plate 45 is fixedly provided with a snap slider 46. The snap slider 46 is located in the snap chute 44 and is threadedly sleeved on the bidirectional screw 43. The two extrusion plates 45 clamp the bottom of the cup body 1. By rotating the bidirectional screw 43, the two extrusion plates 45 can be controlled to approach or move away from each other, which facilitates clamping the cup body 1 by the two extrusion plates 45 to place it stably or releasing the restriction on the cup body 1.

[0038] As Figure 4 , Figure 8 , Figure 9 shown, on the bottom plate 4, a support frame 6 is arranged outside the vertical rod 41. The support frame 6 includes an annular plate 61, a support plate 63 and a plurality of support rods 62. The support plate 63 and the annular plate 61 are respectively arranged at the upper and lower ends of the plurality of support rods 62, and the annular plate 61 is connected to the bottom plate 4 by bolts. A mixing cup 3 is inserted on the support plate 63. The upper end of the mixing cup 3 is set to be open, and a cover plate is threadedly sleeved. An electric motor is arranged above the cover plate, and a stirrer 32 is arranged below. The stirrer 32 is connected to the output shaft of the electric motor and is located in the mixing cup 3. The lower end of the mixing cup 3 is provided with an output pipe 31. A valve body is arranged at the junction of the output pipe 31 and the mixing cup 3. The output pipe 31 can extend into the cup body 1. The sand mixing liquid taken out by the staff is poured into the mixing cup 3. After the cover plate is threadedly sleeved on the mixing cup 3, the stirrer 32 is rotated by the electric motor. After the sand mixing liquid is fully stirred and mixed, the valve body is opened, so that the sand mixing liquid flows out from the lower end of the output pipe 31 and flows into the cup body 1 until the liquid level in the cup body 1 is flush with the maximum scale value 12. In order to ensure that the sand mixing liquid flows into the cup body 1, the mixing cup 3 is located above the cup body 1.

[0039] As Figure 2 , Figure 3 shown, in order to reduce the influence of the liquid flow on the sedimentation of the sand in the cup body 1 caused by the liquid turning in the cup body 1, a sealing cover 2 is threadedly sleeved at the opening of the cup body 1. A first adjusting screw 21 is threadedly penetrated through the middle of the sealing cover 2. The lower end of the first adjusting screw 21 is provided with a lifting disc 22. A sealing gasket 23 is arranged on the lifting disc 22. The sealing gasket 23 is in sliding contact with the side wall of the cup body 1. After the liquid level is flush with the maximum scale value 12, the sealing cover 2 is threadedly sleeved on the cup body 1, and the first adjusting screw 21 is rotated to adjust the height of the lifting disc 22, so that the lower side surface of the lifting disc 22 is flush with the maximum scale value 12 to limit the turning of the liquid.

[0040] As Figure 6As shown in the figure, in order to stably place the device, a cavity 47 is provided below the bottom plate 4, and a sealing layer is provided on the lower side of the bottom plate 4. A second adjusting screw 49 is threadedly penetrated through the top wall of the cavity 47. The lower end of the second adjusting screw 49 is connected to a lifting plate 48 through a bearing, and the lifting plate 48 is in sliding contact with the side wall of the cavity 47. After the bottom plate 4 is placed on the workbench, the staff rotates the second adjusting screw 49 to control the lifting of the lifting plate 48, increase the space formed by the lifting plate 48, the workbench and the cavity 47, and reduce the pressure in this space. Under the action of the pressure difference, the bottom plate 4 is controlled to stably fit on the workbench.
