Description

Technical Field

[0001] The present invention relates to the technical field of equipment foundation vibration detection, in particular to an equipment foundation and a measurement method for measuring its own vibration or deflection by utilizing resistance change. Background Art

[0002] A vibration damping base is a special device used to reduce the vibration and noise transmitted from motors, engines or other vibrating equipment to the supporting structure or environment. Its core goal is to reduce the vibration transmissibility, improve equipment stability and protect surrounding structures through elastic isolation or damping absorption.

[0003] At present, after long-term operation, conventional vibrating electromechanical equipment will cause varying degrees of damage to the vibration reduction system due to the quality of various vibration reduction pad materials and construction, as well as factors in the operating environment. Minor vibration reduction faults are difficult to judge with the naked eye. In addition, there are many vibration reduction devices in the machine room, and it is impossible to measure and observe each vibration reduction pad during inspection. As a result, the frequency of unit failures increases and the unit operating efficiency decreases. The subsequent treatment is more difficult and the cost increases.

[0004] On the other hand, existing equipment generally lacks active monitoring capabilities, making it unable to automatically detect vibration or deflection in real time. For example, while some existing monitoring solutions use mechanical displacement sensors, these solutions typically require periodic manual checks or rely on external triggering mechanisms, failing to achieve true real-time monitoring. This often means that abnormal vibration or deflection often goes undetected, delaying maintenance and even leading to serious accidents. Summary of the Invention

[0005] In view of the problems in the prior art, the present invention provides a device for measuring the vibration or deflection of a device foundation by utilizing resistance changes.

[0006] The technical solution adopted by the present invention to solve its technical problems is: a device foundation for measuring the vibration or deflection of a device by using resistance change, comprising a positioning device, a supporting device fixedly installed on the top of the positioning device, and piezoresistive resistor elements fixedly installed at the four corners of the top of the positioning device, the supporting device comprising a contact plate, a spring shock absorber and a device base, the contact plates symmetrically fixedly installed on both sides of the device base, the spring shock absorbers symmetrically fixedly installed on the two ends of the bottom of the device base, the positioning device comprising a steel plate base, a steel backer, a photoelectric displacement sensor, a plastic cushion layer, a cement base and a plastic plate, the plastic cushion layer fixedly installed on the top of the cement base, the steel plate base fixedly installed on the top of the plastic cushion layer, the steel backer fixedly installed on the top of the cement base, and the steel backers are symmetrically arranged, the photoelectric displacement sensor is equidistantly fixedly installed between the two steel backers, and the plastic plate is fixedly installed on the side end of the steel backer close to the steel plate base; The piezoresistive element is electrically connected to an external integrated platform. When the equipment base descends and causes the contact plate to contact the piezoresistive element, the resistance value of the piezoresistive element changes, thereby sending an alarm signal to the integrated platform, thereby detecting vibration or deflection of the equipment foundation.

[0007] Specifically, the above-mentioned method for measuring the device foundation of measuring its own vibration or deflection by using resistance change includes the following steps: S1. Resistance change monitoring: The vibration or deflection of the device base is monitored in real time through the piezoresistive element. In its initial state, the resistance value of the piezoresistive element is R0. When the device base vibrates or deflects, causing the contact plate to contact the piezoresistive element, the pressure on the piezoresistive element changes, and its resistance value R changes accordingly. The change in resistance value ΔR is inversely proportional to the pressure, that is, the greater the pressure, the smaller the resistance value. S2. Establishing the relationship between resistance and displacement: Calibrate the device in a laboratory environment to obtain a quantitative relationship between the resistance change and the displacement of the device platform. By applying different displacements, the corresponding resistance changes are measured, and a corresponding curve or mathematical model is established between the two. This includes: the relationship between the resistance change ΔR of the piezoresistive element and Δh when the device platform drops downward by Δh. This is specifically determined by fitting the formula ΔR = f(Δh), where f represents the functional relationship between the two. S3. Alarm and data feedback: When the resistance value changes beyond the preset threshold, the piezoresistive element sends an alarm signal to the integrated platform. After receiving the alarm signal, the integrated platform triggers an alarm reminder on the one hand, and receives and processes the resistance change data on the other hand. The integrated platform calculates the actual displacement of the equipment base based on the resistance change data and the pre-established resistance-displacement relationship. If the preset resistance change threshold is ΔR0, when ΔR>ΔR0 is detected, the integrated platform determines that the equipment base has abnormal vibration or deflection, issues an alarm, and calculates the specific displacement Δh = f⁻ 1 (ΔR), to achieve real-time monitoring and feedback of the basic status of the equipment and display the results to the outside world; S4. Data Conversion and Analysis: The integrated platform uses the calibrated resistance-displacement relationship to convert resistance change data into actual displacement or vibration amplitude. Based on the corresponding relationship between resistance change and displacement, the integrated platform calculates and displays the vibration amplitude and deflection angle of the equipment foundation. Simultaneously, the integrated platform uses built-in analysis algorithms to perform trend analysis and fault prediction on the monitoring data. This includes: if the resistance value continues to decrease and the rate of change accelerates, it indicates that the equipment base is likely to sink or deflect further, thereby providing an early warning to the outside world so that measures can be taken. S5. Feedback and control: Based on the analysis results, the integrated platform automatically adjusts the equipment operating parameters or prompts for maintenance; including: if the vibration amplitude of the equipment foundation is detected to exceed the safe range, the integrated platform automatically reduces the equipment speed or load, and prompts to check the stability of the vibration reduction system and the equipment foundation; the integrated platform conducts a comprehensive analysis of the monitoring data and the equipment operating parameters, and automatically adjusts the equipment operating status according to the analysis results, including reducing the motor speed and adjusting the load distribution, to reduce the impact of vibration and deflection on the equipment operation, and ensure the safe and stable operation of the equipment.

[0016] Beneficial effects of the present invention: First, the present invention locates a photoelectric displacement sensor between two steel backrests, and the photoelectric displacement sensor is horizontally aligned with the steel plate base, so that it can detect whether the steel plate base is offset during operation. At the same time, the piezoresistive element is vertically aligned with the contact plate.

DETAILED DESCRIPTION

[0022] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] Example 1 likeFigure 1 、 Figure 2 and Figure 3 As shown, a device for measuring the vibration or deflection of an equipment foundation by utilizing resistance change of the present invention includes a positioning device 2, a supporting device 1 is fixedly installed on the top of the positioning device 2, and pressure-sensitive resistor elements 3 are fixedly installed at the four corners of the top of the positioning device 2, the supporting device 1 includes a contact plate 4, a spring shock absorber 5 and an equipment base 6, the contact plate 4 is symmetrically fixedly installed on both sides of the equipment base 6, and the spring shock absorber 5 is symmetrically fixedly installed at both ends of the bottom of the equipment base 6, the positioning device 2 includes a steel plate base 7, a steel backer 8, a photoelectric displacement sensor 9, a plastic cushion layer 10, a cement base 11 and a plastic plate 12, the plastic cushion layer 10 is fixedly installed on the top of the cement base 11, the steel plate base 7 is fixedly installed on the top of the plastic cushion layer 10, the steel backer 8 is fixedly installed on the top of the cement base 11, and the steel backers 8 are symmetrically arranged, the photoelectric displacement sensor 9 is equidistantly fixedly installed between the two steel backers 8, and the plastic plate 12 is fixedly installed on the side end of the steel backer 8 close to the steel plate base 7.

[0025] The working principle of Example 1 is as follows: when in use, the spring damper 5 is arranged between the device base 6 and the steel plate base 7, so that the spring damper 5 can filter the vibration generated by the motor above the device base 6. At the same time, the plastic plate 12 is squeezed into contact with the outer surface of the steel plate base 7 through the steel backing 8, and the plastic cushion layer 10 is installed between the steel plate base 7 and the cement base 11, so that the vibration transmitted by the steel plate base 7 can be reduced. Subsequently, after the device base 6 and the spring damper 5 have been running for a long time, the energy efficiency of the plastic cushion layer 10 and the spring damper 5 gradually decreases, causing the device base 6 to deviate downward, causing the contact plate 4 to contact the piezoresistive resistor element 3 , there is an electrical connection between the pressure-sensitive resistor element 3 and the external control platform, so that when the pressure-sensitive resistor element 3 is triggered, an alarm can be sent to the control platform to remind the property personnel that the spring shock absorber 5 and the plastic cushion layer 10 have failed. In addition, the photoelectric displacement sensor 9 is horizontally aligned with the steel plate base 7, so that the position of the steel plate base 7 can be monitored in real time. When the steel plate base 7 is offset during long-term operation, the photoelectric displacement sensor 9 will display the displacement of the steel plate base 7 according to the set value, which can facilitate the property personnel to judge whether the steel plate base 7 has displaced, and complete the monitoring of the spring shock absorber 5 and the steel plate base 7.

[0026] Specifically, it is implemented by the following method: S1. Resistance change monitoring: The vibration or deflection of the device base is monitored in real time through the piezoresistive element. In its initial state, the resistance value of the piezoresistive element is R0. When the device base vibrates or deflects, causing the contact plate to contact the piezoresistive element, the pressure on the piezoresistive element changes, and its resistance value R changes accordingly. The change in resistance value ΔR is inversely proportional to the pressure, that is, the greater the pressure, the smaller the resistance value. S2. Establishing the relationship between resistance and displacement: Calibrate the device in a laboratory environment to obtain a quantitative relationship between the resistance change and the displacement of the device platform. By applying different displacements, the corresponding resistance changes are measured, and a corresponding curve or mathematical model is established between the two. This includes: the relationship between the resistance change ΔR of the piezoresistive element and Δh when the device platform drops downward by Δh. This is specifically determined by fitting the formula ΔR = f(Δh), where f represents the functional relationship between the two. S3. Alarm and data feedback: When the resistance value changes beyond the preset threshold, the piezoresistive element sends an alarm signal to the integrated platform. After receiving the alarm signal, the integrated platform triggers an alarm reminder on the one hand, and receives and processes the resistance change data on the other hand. The integrated platform calculates the actual displacement of the equipment base based on the resistance change data and the pre-established resistance-displacement relationship. If the preset resistance change threshold is ΔR0, when ΔR>ΔR0 is detected, the integrated platform determines that the equipment base has abnormal vibration or deflection, issues an alarm, and calculates the specific displacement Δh = f⁻ 1 (ΔR), to achieve real-time monitoring and feedback of the basic status of the equipment and display the results to the outside world; Furthermore, the above measurement method can be further intelligentized to realize the function of digital inspection: S4. Data Conversion and Analysis: The integrated platform uses the calibrated resistance-displacement relationship to convert resistance change data into actual displacement or vibration amplitude. Based on the corresponding relationship between resistance change and displacement, the integrated platform calculates and displays the vibration amplitude and deflection angle of the equipment foundation. Simultaneously, the integrated platform uses built-in analysis algorithms to perform trend analysis and fault prediction on the monitoring data. This includes: if the resistance value continues to decrease and the rate of change accelerates, it indicates that the equipment base is likely to sink or deflect further, thereby providing an early warning to the outside world so that measures can be taken. S5. Feedback and control: Based on the analysis results, the integrated platform automatically adjusts the equipment operating parameters or prompts for maintenance; including: if the vibration amplitude of the equipment foundation is detected to exceed the safe range, the integrated platform automatically reduces the equipment speed or load, and prompts to check the stability of the vibration reduction system and the equipment foundation; the integrated platform conducts a comprehensive analysis of the monitoring data and the equipment operating parameters, and automatically adjusts the equipment operating status according to the analysis results, including reducing the motor speed and adjusting the load distribution, to reduce the impact of vibration and deflection on the equipment operation, and ensure the safe and stable operation of the equipment.

Subsequently, when the first rack 17 is displaced, it also drives the extension column 31 to displace through the square frame 36, so that the displacement seat 33 can move between the equipment base 6 and the steel plate base 7, and fit with the equipment base 6 and the steel plate base 7 respectively through the plastic layer 32, so that it can be allowed When the device base 6 vibrates, the stability of the device base 6 is improved, and when the square frame 36 is displaced, it can drive the third rack 39 to displace at the bottom end of the second gear 37, so that the second gear 37 can drive the third gear 38 and the connecting arm 30 to rotate at the same time. When the displacement seat 33 moves between the device base 6 and the steel plate base 7, the connecting arm 30 can be flipped upward, so that the covering sleeve 29 can be rotated to be close to the motor surface above the device base 6. When the motor is running, the fan 28 can be turned on to transport air to the inside of the covering sleeve 29, so that the air can contact the motor surface and quickly dissipate heat from the motor surface. When the device is in use, the displacement seat 33 is inserted between the device base 6 and the steel plate base 7, so that the plastic layer 32 can be in contact with the equipment pedestal 6 and the steel plate base 7, thereby reducing the fluctuation amplitude of the equipment pedestal 6. At the same time, the covering sleeve 29 can be in contact with the outer surface of the motor, so that the fan 28 can deliver air to the surface of the motor when it is running, and can enhance the heat dissipation of the motor under high load. At the same time, when the hydraulic cylinder 20 is started, the covering plate 23 can press the bottom end of the steel backer 8. At the same time, the key 22 can be inserted into the interior of the steel plate base 7, so that the stability of the steel plate base 7 can be improved, and the high-frequency vibration of the steel plate base 7 when the motor is running under high load can be avoided. At the same time, the covering plate 23 is in contact with the steel backer 8, and the key 22 is in contact with the steel plate base 7, so that the supporting strength of the steel plate base 7 can be improved, which is convenient for the motor to run under high load for a short time.When the motor does not need to run under high load, the hydraulic cylinder 20 can be opened again to drive the synchronous frame 19 to reset, so that the synchronous frame 19 can be displaced to the end away from the steel backer 8. At this time, the displacement seat 33 can be pulled out from between the equipment base 6 and the steel plate base 7. At the same time, the covering plate 23 can be pulled away from the steel backer 8, so that the extension plate 24 can be detached from the outer ring of the vertical rod 14, and the key 22 can be removed from the inside of the steel plate base 7, so that the spring damper 5 and the plastic cushion layer 10 can resume normal operation, which is convenient for the motor to perform daily output work. At the same time, when the displacement seat 33 is pulled out from between the equipment base 6 and the steel plate base 7 When the third rack 39 is pulled out of the motor, the third rack 39 can be displaced in the opposite direction at the bottom end of the second gear 37, so that the third gear 38 can drive the connecting arm 30 to flip toward the end away from the equipment base 6, so that the cover sleeve 29 can be separated from the surface of the motor, which facilitates the daily internal heat dissipation of the motor. At the same time, the outer ring surface of the key 22 is fixedly mounted with a plastic layer, which allows the key 22 to have a slight displacement inside the alignment groove 13, avoiding the key 22 from breaking. The first rack 17 and the second rack 25 are staggered to avoid interference between the first rack 17 and the second rack 25 during displacement, thus completing the work.

2. The method for measuring the device foundation of measuring its own vibration or deflection by using resistance change according to claim 1, comprising the following steps: S1. Resistance change monitoring: The vibration or deflection of the device base (6) is monitored in real time by the piezoresistive element (3). In the initial state, the resistance value of the piezoresistive element (3) is R0. When the device base (6) vibrates or deflects, causing the contact plate (4) to contact the piezoresistive element (3), the pressure on the piezoresistive element (3) changes, and its resistance value R changes accordingly. The change in resistance value ΔR is inversely proportional to the pressure, that is, the greater the pressure, the smaller the resistance value. S2. Establishing the relationship between resistance and displacement: Calibrate the device in a laboratory environment to obtain a quantitative relationship between the resistance change and the displacement of the device platform seat (6). By applying displacements of different sizes and measuring the corresponding resistance changes, a corresponding curve or mathematical model between the two is established, including: if the device platform (6) drops downward by Δh, the relationship between the resistance value change ΔR of the piezoresistive element (3) and Δh is determined specifically by the formula ΔR = f(Δh) obtained by fitting, where f represents the functional relationship between the two; S3. Alarm and data feedback: When the resistance value changes beyond the preset threshold, the piezoresistive element (3) sends an alarm signal to the integrated platform. After receiving the alarm signal, the integrated platform triggers an alarm reminder on the one hand, and receives and processes the resistance change data on the other hand. The integrated platform calculates the actual displacement of the device base (6) based on the resistance change data and the pre-established resistance and displacement relationship. If the preset resistance change threshold is ΔR0, when ΔR > ΔR0 is detected, the integrated platform determines that the device base (6) has abnormal vibration or deflection, issues an alarm and calculates the specific displacement Δh = f⁻ 1 (ΔR), to achieve real-time monitoring and feedback of the basic status of the equipment and display the results to the outside world; S4. Data Conversion and Analysis: The integrated platform uses the calibrated resistance-displacement relationship to convert resistance change data into actual displacement or vibration amplitude. Based on the corresponding relationship between resistance change and displacement, the integrated platform calculates and displays the vibration amplitude and deflection angle of the equipment foundation. Simultaneously, the integrated platform uses built-in analysis algorithms to perform trend analysis and fault prediction on the monitoring data. This includes: if the resistance value continues to decrease and the rate of change accelerates, it indicates that the equipment base is likely to sink or deflect further, thereby providing an early warning to the outside world so that measures can be taken. S5. Feedback and control: Based on the analysis results, the integrated platform automatically adjusts the equipment operating parameters or prompts for maintenance; including: if the vibration amplitude of the equipment foundation is detected to exceed the safe range, the integrated platform automatically reduces the equipment speed or load, and prompts to check the stability of the vibration reduction system and the equipment foundation; the integrated platform conducts a comprehensive analysis of the monitoring data and the equipment operating parameters, and automatically adjusts the equipment operating status according to the analysis results, including reducing the motor speed and adjusting the load distribution, to reduce the impact of vibration and deflection on the equipment operation, and ensure the safe and stable operation of the equipment.
