[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Embodiment 1: In the present invention, referring to Figure 1 - Figure 8 As shown: a cement consistency setting time measuring device, comprising a measuring box 3, a consistency setting control component 10 and an adaptive monitoring component 11; The consistency coagulation control component 10 and the adaptive monitoring component 11 are respectively installed in the inner space of the measuring box 3, and the adaptive monitoring component 11 is located around the consistency coagulation control component 10 to monitor the various characteristic changes of the cement paste in real time from all directions and angles; The consistency coagulation control assembly 10 includes a driving energy-saving motor 101 and a belt output speed regulating structure 102; The driving energy-saving motor 101 is installed on the surface of the measuring box 3 through a motor frame. The belt output speed regulation structure 102 consists of a pulley structure and a speed regulator. The output end of the driving energy-saving motor 101 is connected to the belt output speed regulation structure 102. The output end of the belt output speed regulation structure 102 is connected to a transmission key shaft 103. A temperature-controlled consistency coagulation chamber 104 is installed on the outside of the side end of the transmission key shaft 103. An auxiliary working chamber 105 is installed on the left side end of the temperature-controlled consistency coagulation chamber 104.

[0021] The transmission key shaft 103 passes through the temperature-controlled consistency coagulation chamber 104 and the auxiliary operation chamber 105 in sequence, and a heating and stirring rake 106 is installed on the outer peripheral side of the side end of the transmission key shaft 103. The side end surfaces of the temperature-controlled consistency coagulation chamber 104 and the auxiliary operation chamber 105 are connected with an appropriate amount distributor 108, and the side end of the appropriate amount distributor 108 is connected with a liquid adding guide pump pipe 107.

[0022] In a specific solution, when measuring, the driving energy-saving motor 101 is made to run stably, and the power is efficiently transmitted to the transmission key shaft 103 through the belt output speed regulation structure 102. The transmission key shaft 103 drives the heating and stirring rakes 106 tightly installed on the outer circumference of its side end to rotate rapidly. The heating and stirring rakes 106 adopt a special bionic design, and the shape of the blades imitates the turbine structure. During the rotation process, it can not only generate a strong axial thrust to ensure that the cement is fully tumbled and mixed in the temperature-controlled consistency coagulation chamber 104 (a uniform lighting system is set in the temperature-controlled consistency coagulation chamber 104 to simulate natural lighting conditions), but also form radial turbulence to effectively break the agglomeration of cement particles, so that the cement and the subsequently added water are quickly and evenly contacted. When the cement is initially dispersed under the action of the heating and stirring rakes 106, the auxiliary operation chamber 105 connected to the left side of the temperature-controlled consistency coagulation chamber 104 operates synchronously, and the appropriate amount distributor 108 installed on the side surface of the chamber After receiving the control system command, a preset volume of water is accurately extracted through the liquid adding pump tube 107, and injected into the temperature-controlled consistency coagulation chamber 104 and the auxiliary operation chamber 105 at a stable and uniform flow rate. In this process, the appropriate amount distributor 108 uses a high-precision flow sensor and an intelligent regulating valve, and the flow measurement accuracy can reach 0.1ml. It can accurately control the amount of water added according to the type, amount and required water-cement ratio of cement, ensure the accuracy of the initial proportion of the cement slurry, and lay the foundation for the reliability of subsequent test results. From the moment the cement and water begin to mix, the adaptive monitoring component 11 surrounding the consistency coagulation control component 10 starts the monitoring task in all directions, so that the horizontal positioning sliding electromagnetic wire rail 111 on the horizontal drive connecting frame 110 quickly drives the positioning saddle 112 to move to the initial monitoring position, driving the cleaning and drying structure in the vertical short-distance adjustment rail 1190 to retreat to a safe area to avoid interference with the test.

[0023] Embodiment 2: In the present invention, according to Figure 2 - Figure 5 , Figure 7 and Figure 8 As shown, the adaptive monitoring assembly 11 includes a lateral drive connecting frame 110, two sets of bearing brackets 114 and a lifting cylinder 116; The two groups of supporting brackets 114 are both fastened to the top wall surface of the measuring box 3, and the lifting cylinders 116 are installed on the top of the side ends of the two groups of supporting brackets 114. The side ends of the lifting cylinders 116 are slidably connected with azimuth rotating motor boxes 117, and the output ends of the azimuth rotating motor boxes 117 are rotatably connected with angle rotating racks 118. The bottoms of the angle rotating racks 118 are connected with standard test rods 119 and initial setting test needles through miniature electromagnetic telescopic guide rods, and the sides of the standard test rods 119 and the initial setting test needles are connected with data filtering collectors 115 through optical fiber lines, which are used to automatically form high-precision measurements at different stages of cement hydration reaction.

[0024] A transverse displacement guide rail is installed on the inner surface of the measuring box 3, and the top end of the transverse displacement guide rail is connected to a bearing drive frame 1192 via a positioning sliding block. The side end of the bearing drive frame 1192 is fastened with a short-distance regulating guide rail 1193, and a sliding distance measuring block 1191 is installed on the top of the short-distance regulating guide rail 1193. The sliding distance measuring block 1191 is slidingly connected to the bottom wall surface of the inner frame of the measuring box 3, and the side end of the short-distance regulating guide rail 1193 is slidingly connected with an adjusting guide rod 1195, and a final setting test needle 1194 is installed at the bottom of the adjusting guide rod 1195.

[0025] The transverse driving connecting frame 110 is tightly connected to the inner wall surface of the measuring box 3, and a transverse positioning sliding electromagnetic wire rail 111 is installed on the side end of the transverse driving connecting frame 110. The external sliding connection of the transverse positioning sliding electromagnetic wire rail 111 is connected with a positioning saddle 112, and the bottom end of the positioning saddle 112 is installed with a vertical short-distance adjustment guide rail 1190. The internal sliding connection of the vertical short-distance adjustment guide rail 1190 is connected with a cleaning and drying structure for cleaning and drying the standard test rod 119, the initial setting test needle and the final setting test needle 1194 after the test. Optical fiber refractive index sensors 113 are installed on both ends of the transverse positioning sliding electromagnetic wire rail 111.

[0026] In a specific solution, the lateral positioning sliding electromagnetic rail 111 drives the positioning saddle 112 to move, driving the optical fiber refractive index sensor 113 to a predetermined monitoring position, and starts to collect the optical property data of the cement slurry in real time, providing an early basis for the subsequent analysis of the cement hydration process. Then, when the cement and water are initially mixed to form a slurry, the lifting cylinder 116 is started according to the preset program of the external PLC controller, driving the azimuth rotation motor box 117, the angle rotating frame 118 and the standard test rod 119 at the bottom to descend, so that the standard test rod 119 is vertically inserted into the slurry at a stable and precisely controlled speed such as 2 mm / s, and the optical fiber line on the side transmits the mechanical signals such as the resistance and sinking depth of the test rod to the data filter collector 115 in real time, so that the data filter The wave collector 115 uses advanced digital signal processing algorithms to quickly remove noise interference caused by mixing, equipment vibration, etc., accurately obtain the initial consistency information of the cement slurry, and determine whether it meets the standard consistency requirement range. If deviations are found, the external PLC controller immediately adjusts the mixing parameters for optimization. As the cement hydration reaction continues to advance, the temperature and consistency of the cement slurry gradually change. When the monitoring system predicts that the cement is approaching the initial setting stage based on the previously collected data and the built-in cement coagulation model, the lifting cylinder 116 and the azimuth rotation motor box 117 quickly cooperate to make the lifting cylinder 116 lift the standard test rod 119, and another set of azimuth rotation motor boxes 117 accurately rotate the angle rotating frame 118 to switch the initial setting test needle to the insertion position, and With more acute perception, the subtle features of the initial setting moment are detected. Similarly, through the optical fiber line and the data filter collector 115, key data such as the change of the test needle insertion resistance and the change of the slurry surface state are collected in real time and with high precision, and the initial setting time node is accurately locked and recorded. When approaching the final setting stage, the lateral displacement guide rail plays a role, so that the load-bearing drive frame 1192 moves to the specified position according to the preset program under the guidance of the positioning sliding block, and the short-distance control guide rail 1193 drives the final setting test needle 1194 at the bottom of the adjustment guide rod 1195 to accurately descend and insert into the slurry. The sliding distance measuring block 1191 feeds back the test needle position information in real time to ensure that the insertion depth is accurate. At the same time, the data collected by the final setting test needle 1194 is also transmitted through a similar optical fiber line and filtered collection process. , determine the final setting time, and provide a complete data chain for fully understanding the setting characteristics of cement. After completing the measurement of all predetermined test indicators, the horizontal drive connecting frame 110 drives the positioning saddle 112 to move, so that the cleaning and drying structure in the vertical short-distance adjustment guide rail 1190 is quickly in place. First, the high-pressure water spray cleaning program is started. The multi-directional and multi-angle nozzles spray clean water with appropriate pressure. Combined with the rotating brush, the cement residue attached to the standard test rod 119, the initial setting test needle and the final setting test needle 1194 is thoroughly removed. After the cleaning is completed, the microwave drying function is immediately turned on. The hot air generated by the efficient heating element is used to dry the test component to a state that can be used again in a short time, such as 5-10 minutes, to prepare for the next test. During the entire test process,The display data terminal 2 installed on the side of the measuring box 3 updates and displays all key data in real time, including cement feeding amount, mixing parameters, test rod and test needle measurement data at each stage, optical data collected by the optical fiber refractive index sensor 113, and cement consistency and setting time results calculated based on these data.

[0031] An infrared generator is installed at the side end of the small adjustment shaft arm 9, and the infrared generator is located outside the auxiliary operation chamber 105 through a fixed-point focusing controller to form a fixed-point operation.

[0032] In a specific solution, during the measurement operation, the rotating motor inside the motor-carrying rotating frame 13 drives the damping rotating member inside the damping friction rotating box 14, so that the sealing soft plate 15 slides along the top of the temperature-controlled consistency coagulation chamber 104 to seal or slide open, so that the consistency coagulation control component 10 and the adaptive monitoring component 11 can work effectively. In the above operation, the positioning frame 8 drives the small adjustment shaft arm 9 and the infrared generator to work at a fixed point outside the auxiliary operation chamber 105 in cooperation with the transverse ball guide rail 12, so that the infrared generator When the adaptive monitoring component 11 measures the temperature-controlled consistency coagulation chamber 104, the infrared generator simultaneously performs ultrasonic vibration treatment on the material in the auxiliary operation chamber 105, so that in the cement slurry preparation stage, the agglomerated cement particles can be effectively broken up to make the particle size distribution more uniform, ensuring that it can be quickly and fully dissolved when mixed with water later, improving the initial uniformity of the cement slurry, and laying a good foundation for accurately measuring the consistency coagulation time. In the test process, by applying infrared radiation of a specific frequency to the cement slurry, the water content can be quickly judged according to its absorption, reflection and other characteristics. The viscosity and coagulation state of the mud are determined, and then, based on the judged and analyzed data, the data of the above-mentioned adaptive monitoring component 11 are integrated and complemented in multiple dimensions, so that on the one hand, the multiple groups of detection structures in the adaptive monitoring component 11 monitor the cement paste from the angles of temperature, stress, dielectric constant, etc., and combine the microstructure image captured by the built-in ultra-micro high-definition camera to provide physical parameter information combining micro and macro. On the other hand, the infrared generator focuses on the optical property level, and reflects the chemical structure changes in the cement hydration process based on the feedback data of the interaction between infrared radiation and cement paste, so that the data of the two are integrated, and the fusion algorithm run by the central coordination processor in the external PLC controller is mutually verified and calibrated, so that when the infrared light reflectance data shows that the cement is close to initial setting, and the insertion resistance of the standard test rod 119 for mechanical monitoring has not reached the traditional initial setting threshold, the external PLC controller will automatically start the secondary monitoring process, and use the distributed microprocessor network and the data filter collector 115 to quickly re-collect and analyze the data, accurately determine the real coagulation state, avoid misjudgment caused by a single data source, and greatly improve the reliability and accuracy of the measurement results.
