Description

Technical Field

[0001] This invention relates to the field of electric six-speed rotational viscometer technology, specifically to an electric six-speed rotational viscometer. Background Technology

[0002] The electric six-speed rotational viscometer is a professional instrument used to accurately measure the rheological properties of liquids, especially non-Newtonian fluids such as drilling fluids. It is named for its six selectable fixed rotational speeds and is an important tool for fluid performance analysis in the petroleum, chemical and other fields.

[0003] During use, traditional electric six-speed rotary viscometers are prone to radial swaying or eccentric vibration due to uneven fluid resistance and installation alignment errors when the internal stirring outer cylinder rotates at high speed. This changes the concentricity of the two cylinders and the uniformity of the shear gap, resulting in torque signal fluctuations, which directly affect the measurement accuracy and repeatability.

[0004] To address the aforementioned issues, we propose an electric six-speed rotational viscometer. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an electric six-speed rotary viscometer. The device utilizes the relative rotation of the annular groove block and the fixed vertical shaft. Through the oblique engagement of the connecting inclined frame and the limiting guide rod, the annular reset piston is driven to squeeze silicone oil. This is then transmitted via a closed hydraulic circuit to push multiple sets of arc-shaped squeezing blocks to synchronously and radially clamp the stirring outer cylinder. This effectively suppresses eccentric swaying and radial vibration during the rotation of the stirring outer cylinder, ensuring a uniform and constant shear gap between the fixed inner cylinder and the stirring outer cylinder. It avoids shear rate fluctuations caused by cylinder swaying, significantly improving the accuracy of viscosity detection results.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an electric six-speed rotary viscometer, comprising a support base, two support vertical rods fixedly installed on the rear side of the top of the support base, a detection head fixedly installed on the top of the two support vertical rods, an annular groove block fixedly installed on the output shaft of the detection head, a fixed vertical shaft being provided inside the annular groove block, a snap-fit ​​annular groove being opened inside the annular groove, and a stirring outer cylinder being snapped inside the snap-fit ​​annular groove; A reset cavity is provided on the upper side inside the annular groove block, and an annular reset piston is slidably installed on the upper side inside the reset cavity. An annular electric slide rail is provided on the bottom periphery of the detection head, and the output part of the annular electric slide rail is embedded and fixedly installed in the top of the annular groove block. The rotation effect of the annular groove block is ensured by the annular electric slide rail. Several extrusion components are equidistantly arranged on the lower side inside the reset cavity. A connecting inclined frame is fixedly installed at the bottom of the annular reset piston, and a limiting guide rod is slidably installed on the inner wall of the connecting inclined frame. One end of the limiting guide rod is fixedly connected to the surface of the fixed vertical shaft.

[0007] Furthermore, the upper end of the fixed vertical shaft extends through the upper side of the inner wall of the annular groove block and the upper side of the inner wall of the reset cavity to the top of the annular groove block, and the upper end of the fixed vertical shaft is fixedly connected to the surface of the detection head. The lower end of the fixed vertical shaft is threadedly connected to a fixed inner cylinder. The inner wall of the annular reset piston is tightly fitted with the fixed vertical shaft. The detection head has the function of viscosity detection, which is a mature existing technology and will not be described in detail in this application. The output shaft of the detection head can drive the annular groove block to rotate without affecting the fixing effect of the fixed vertical shaft, ensuring the relative motion state of the fixed inner cylinder and the stirring outer cylinder, and ensuring the basic function of the device.

[0008] Furthermore, the extrusion assembly includes a push groove formed on one side inside the reset cavity, a push piston is slidably installed inside the push groove, an extrusion groove is formed on the inner wall of the snap ring groove near the push groove, and an arc-shaped extrusion block is slidably installed in the inner wall of the extrusion groove, a delivery pipe is fixedly installed on one side of the inner wall of the push groove, and a prompting component is provided on the inner wall of the push groove above the push piston.

[0009] Furthermore, both the pushing groove and the reset chamber located below the annular reset piston are filled with silicone oil. One end of the delivery pipe extends through to the inside of the extrusion groove. The delivery pipe is used to introduce the silicone oil into the extrusion groove. The silicone oil fills the extrusion groove to suppress the shaking of the stirring outer cylinder when the stirring outer cylinder is working, thereby ensuring the accuracy of the detection.

[0010] Furthermore, the upper and lower sides of the arc-shaped extrusion block are integrally formed with two protrusions, and the inner wall of the extrusion groove is provided with corresponding sliding grooves. The protrusions are used to slide and cooperate with the corresponding sliding grooves to ensure that the arc-shaped extrusion block remains stable when sliding.

[0011] Furthermore, the prompting component includes an L-shaped sliding groove formed at the top of the push groove, an L-shaped push rod slidably installed on the inner wall of the L-shaped sliding groove, a push square rod fixedly installed on the side of the L-shaped push rod away from the push piston, a receiving groove formed on the surface of the annular groove block on one side of the L-shaped sliding groove, an elastic paddle slidably installed on the inner wall of the receiving groove, and several metal vertical plates fixedly installed on the lower side of the surface of the detection head on the periphery of the annular groove block.

[0012] Furthermore, the bottom of the L-shaped push rod is fixedly connected to the top of the push piston, one end of the push square rod extends through into the interior of the storage groove, and one end of the push square rod is fixedly connected to one side of the surface of the elastic paddle; when the push piston moves, it drives the L-shaped push rod to move synchronously, and the L-shaped push rod drives the elastic paddle to move away from the storage groove through the push square rod. When the stirring outer cylinder deflects, the elastic paddle contacts the metal vertical plate and makes a sound, thereby improving the prompting effect.

[0013] Furthermore, a movable groove plate is slidably installed on the surfaces of the two supporting vertical rods, and a fastening bolt is threadedly connected to one side of the surface of the movable groove plate. Several limiting grooves are opened on the lower periphery of the inner wall of the movable groove plate, and extrusion members are provided inside the several limiting grooves.

[0014] Furthermore, the extrusion component includes a rotating bent block rotatably mounted on the inner wall of the limiting groove. Two retraction springs are fixedly mounted on the upper side of the surface of the rotating bent block, and the upper ends of the two retraction springs are fixedly connected to one side of the inner wall of the limiting groove.

[0015] Furthermore, a solution cylinder is provided inside the movable trough plate. Sponge pads are fixedly installed on the upper and lower surfaces of the inner wall of the rotating bend block near the solution cylinder. These sponge pads are used to protect the surface of the solution cylinder. The retraction spring pulls the rotating bend block back into the limiting groove, with the bottom of the rotating bend block protruding from the limiting groove. During the placement of the solution cylinder, the gravity of the solution cylinder causes the rotating bend block to rotate, thereby maintaining the stability of the solution cylinder during use and improving detection accuracy.

[0016] Compared with the prior art, the present invention provides an electric six-speed rotational viscometer, which has the following beneficial effects: 1. This device utilizes the relative rotation of the annular groove block and the fixed vertical shaft. Through the oblique engagement of the connecting inclined frame and the limiting guide rod, it drives the annular reset piston to squeeze the silicone oil. The silicone oil is then squeezed by multiple sets of arc-shaped extrusion blocks in a synchronous radial gripping motion through a closed hydraulic circuit. This effectively suppresses the eccentric swaying and radial vibration during the rotation of the outer mixing cylinder, ensuring a uniform and constant shear gap between the fixed inner cylinder and the outer mixing cylinder. This avoids shear rate fluctuations caused by cylinder swaying and significantly improves the accuracy of viscosity detection results.

[0017] 2. When the outer stirring cylinder deflects or shakes beyond the limit, the cylinder's sway will cause the corresponding side to push the piston to produce additional displacement. Through the L-shaped transmission structure, the elastic lever extends outward and rotates synchronously with the ring groove block, causing the lever to periodically move the fixed metal vertical plate to produce an audible alert. This can promptly remind the operator to troubleshoot the fault and avoid equipment damage and detection failure.

[0018] 3. When the solution cylinder in this device is placed into the moving tank plate, it automatically rotates and surrounds the cylinder by pressing down on the rotating bend block under its own weight. After being removed, the rotating bend block automatically retracts and resets under the action of the retraction spring, and works with the sponge pad to achieve flexible surface contact. This avoids rigid clamping from scratching the outer wall of the cylinder, and can adapt to solution cylinders within a certain outer diameter range. At the same time, it ensures that there is no axial movement or radial displacement of the cylinder during the detection process, further reducing the impact of external interference on the detection results.

[0019] 4. When the device rotates forward, it automatically completes hydraulic clamping and vibration suppression. When it rotates in reverse, the hydraulic circuit forms a negative pressure, which pushes the piston and the arc-shaped extrusion block to retract and reset synchronously, increasing the ease of use of the device.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1 to 10 This embodiment of an electric six-speed rotational viscometer includes a support base 1. Two support rods 2 are fixedly installed on the rear side of the top of the support base 1. A detection head 3 is fixedly installed on the top of the two support rods 2. An annular groove block 4 is fixedly installed on the output shaft of the detection head 3. A fixed vertical shaft 5 is provided inside the annular groove block 4. The upper end of the fixed vertical shaft 5 extends through the upper side of the inner wall of the annular groove block 4 and the upper side of the inner wall of the reset cavity 8 to the top of the annular groove block 4. The upper end of the fixed vertical shaft 5 is fixedly connected to the surface of the detection head 3. The lower end is threadedly connected to a fixed inner cylinder 501. The inner wall of the annular reset piston 9 is tightly fitted with the fixed vertical shaft 5. The detection head 3 has a viscosity detection function, which is a mature existing technology and will not be described in detail in this application. The output shaft of the detection head 3 can drive the annular groove block 4 to rotate without affecting the fixing effect of the fixed vertical shaft 5, which can ensure the relative movement of the fixed inner cylinder 501 and the stirring outer cylinder 7, and ensure the basic function of the device. The annular groove block 4 has a snap-fit ​​annular groove 6 inside, and the stirring outer cylinder 7 is snapped inside the snap-fit ​​annular groove 6.

[0024] A reset cavity 8 is provided on the upper side inside the annular groove block 4, and an annular reset piston 9 is slidably installed on the upper side inside the reset cavity 8. An annular electric slide rail 10 is provided on the bottom periphery of the detection head 3, and the output part of the annular electric slide rail 10 is embedded and fixedly installed in the top of the annular groove block 4. The annular electric slide rail 10 is used to ensure the rotation effect of the annular groove block 4. Several extrusion components 11 are equidistantly arranged on the lower side inside the reset cavity 8. A connecting inclined frame 18 is fixedly installed at the bottom of the annular reset piston 9. A limiting guide rod 19 is slidably installed on the inner wall of the connecting inclined frame 18. One end of the limiting guide rod 19 is fixedly connected to the surface of the fixed vertical shaft 5. The extrusion assembly 11 includes a push groove 1101 formed inside one side of the reset chamber 8. A push piston 1102 is slidably installed inside the push groove 1101. An extrusion groove 1103 is formed on the inner wall of the snap ring groove 6 near the push groove 1101. An arc-shaped extrusion block 1104 is slidably installed inside the inner wall of the extrusion groove 1103. A delivery pipe 1105 is fixedly installed on one side of the inner wall of the push groove 1101. The push groove 1101 and the reset chamber 8 are both filled with silicone oil on the lower side of the annular reset piston 9. One end of the delivery pipe 1105 extends through to the inner side of the extrusion groove 1103.

[0025] The delivery pipe 1105 is used to introduce silicone oil into the extrusion tank 1103. The silicone oil fills the extrusion tank 1103 to suppress the shaking of the outer stirring tank 7 when it is working, thereby ensuring the accuracy of the test.

[0026] The upper and lower sides of the arc-shaped extrusion block 1104 are integrally formed with two protrusions, and the inner wall of the extrusion groove 1103 is provided with corresponding sliding grooves at corresponding positions. The protrusions are used to slide and cooperate with the corresponding sliding grooves to ensure that the arc-shaped extrusion block 1104 remains stable when sliding. A prompting component 12 is provided on the inner wall of the push groove 1101 above the push piston 1102. The prompting component 12 includes an L-shaped sliding groove 1201 opened at the top of the push groove 1101. An L-shaped push rod 1202 is slidably installed on the inner wall of the L-shaped sliding groove 1201. A push square rod 1203 is fixedly installed on the side of the L-shaped push rod 1202 away from the push piston 1102. A storage groove 1204 is opened on the surface of the annular groove block 4 on one side of the L-shaped sliding groove 1201. An elastic paddle 1205 is slidably installed on the inner wall of the storage groove 1204. Several metal vertical plates 1206 are fixedly installed on the lower side of the surface of the detection head 3 around the annular groove block 4. The bottom of the L-shaped push rod 1202 is fixedly connected to the top of the push piston 1102. One end of the push square rod 1203 extends through into the interior of the storage groove 1204, and one end of the push square rod 1203 is fixedly connected to one side of the surface of the elastic paddle 1205. When the push piston 1102 moves, it drives the L-shaped push rod 1202 to move synchronously. The L-shaped push rod 1202 drives the elastic paddle 1205 to move away from the storage groove 1204 through the push square rod 1203. When the stirring outer cylinder 7 deflects, the elastic paddle 1205 contacts the metal vertical plate 1206 and paddles to make a sound, so as to enhance the prompting effect.

[0027] The surfaces of the two supporting vertical rods 2 are slidably mounted with a movable groove plate 13, and a fastening bolt 14 is threadedly connected to one side of the surface of the movable groove plate 13. Several limiting grooves 15 are opened on the lower periphery of the inner wall of the movable groove plate 13. Each of the limiting grooves 15 is provided with an extrusion member 16. The extrusion member 16 includes a rotating bent block 1601 rotatably mounted on the inner wall of the limiting groove 15. Two retractable tension springs 1602 are fixedly installed on the upper side of the surface of the rotating bent block 1601, and the upper ends of the two retractable tension springs 1602 are fixedly connected to one side of the inner wall of the limiting groove 15. The movable tank plate 13 is equipped with a solution cylinder 17. The upper and lower surfaces of the inner wall of the rotating bending block 1601 near the solution cylinder 17 are fixedly installed with sponge pads 1603. The sponge pads 1603 are used to protect the surface of the solution cylinder 17. The retracting tension spring 1602 pulls the rotating bending block 1601 back into the limiting groove 15, and the bottom of the rotating bending block 1601 is exposed in the limiting groove 15. During the placement of the solution cylinder 17, the gravity of the solution cylinder 17 drives the rotating bending block 1601 to rotate, so as to maintain the stability of the solution cylinder 17 during use and improve the detection accuracy.

[0028] The working principle of the above embodiments is as follows: When the device is in operation, the annular electric slide rail 10 on the detection head 3 drives the annular groove block 4 to rotate continuously. The upper end of the fixed vertical shaft 5 is fixedly connected to the detection head 3 and the lower end is threadedly connected to the fixed inner cylinder 501. The inner cylinder remains stationary. The stirring outer cylinder 7 is engaged with the annular groove block 4 through the snap-fit ​​annular groove 6 and rotates synchronously with the annular groove block 4. A stable relative rotational motion is formed between the fixed inner cylinder 501 and the stirring outer cylinder 7, which applies a shearing action to the fluid to be tested placed in the solution cylinder 17. The detection head 3 obtains viscosity data accordingly. The detection data of the detection head 3 is a well-known technology and will not be described in detail in this application. During rotation, the annular groove block 4 is in a relative motion state with respect to the fixed vertical shaft 5. Under the oblique extrusion force of the inclined frame 18 connected to the annular reset piston 9 relative to the limiting guide rod 19, the annular reset piston 9 can be ensured to move downward. In this way, the annular reset piston 9 extrudes the silicone oil in the reset chamber 8 and also extrudes the silicone oil filled in the push groove 1101. The silicone oil is pressed into the extrusion groove 1103 through the delivery pipe 1105, which in turn pushes the arc-shaped extrusion block 1104 to move towards the snap ring groove 6, so that it abuts against the outer wall of the stirring outer cylinder 7, forming a radial constraint and suppressing the vibration or eccentric shaking of the stirring outer cylinder 7. During the continuous rotation of the annular groove block 4, when the annular reset piston 9 moves to a certain distance, the annular reset piston 9 and the fixed vertical shaft 5 will slip. This will not affect the normal rotation detection effect. When it is necessary to release the limit on the outer stirring cylinder 7, the annular electric slide rail 10 rotates in the reverse direction, and the annular reset piston 9 in the reset chamber 8 moves upward. The movement of the annular reset piston 9 generates negative pressure on the lower side of the reset chamber 8, which causes the silicone oil in the reset chamber 8 to move towards the position of the annular reset piston 9. Through the connection between the reset chamber 8 and the push groove 1101, the pressure is transmitted to the push piston 1102, which pushes it back to the initial position along the push groove 1101. At the same time, the silicone oil in the extrusion groove 1103 flows back through the delivery pipe 1105, and the arc-shaped extrusion block 1104 disengages from the contact with the outer stirring cylinder 7, thus completing the reset. When the outer stirring cylinder 7 deflects or shakes abnormally, it will tilt relative to the locking ring groove 6, resulting in unequal gaps between the outer cylinder and the left and right sides of the ring groove. This asymmetrical gap will translate into changes in the displacement of the piston 1102. Through the L-shaped push rod 1202 and the push square rod 1203 fixedly connected to the piston, the elastic paddle 1205 will extend outward into the receiving groove 1204. Due to different tilting directions, the extension amount of the push square rod 1203 will also change. However, no matter which side the outer cylinder tilts to, this structure can ensure that the elastic paddle 1205 obtains sufficient extension stroke. If the deflection continues, the elastic paddle 1205 will touch the metal vertical plate 1206 fixed to the lower side of the detection head 3 and paddle to make a sound, so as to promptly alert the operator to the abnormal shaking with an auditory signal, thereby effectively ensuring the safe operation of the equipment. During the installation of the solution cylinder 17, the movable slot plate 13 slides up and down along the support vertical rod 2 and is locked in position by the fastening bolt 14. When the solution cylinder 17 is placed in the movable slot plate 13, its gravity presses the rotating bending block 1601 in the extrusion member 16, causing it to overcome the tension of the retraction spring 1602 and rotate downward. The sponge pad 1603 on the inner wall of the rotating bending block 1601 then adheres to the outer wall of the solution cylinder 17 to provide flexible clamping. After the solution cylinder 17 is removed, the retraction spring 1602 pulls the rotating bending block 1601 back into the limiting groove 15.

[0029] This device achieves stable and accurate measurement of fluid viscosity through the combined effects of hydraulically assisted clamping and resetting, audible alerts for abnormal shaking, and a flexible cylinder fixing structure.

[0030] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
