Description

Technical Field

[0001] This invention relates to the field of sensors, and more particularly to a sensor-based displacement monitoring device and an automatic alarm method. Background Technology

[0002] Sensors are often needed for monitoring industrial automated production lines, bridges, and geological disasters. They can not only monitor the environment in real time, but also ensure safety during use by detecting subtle changes.

[0003] Chinese Patent CN111637844B discloses a displacement sensor and displacement monitoring device based on fiber optic grating sensing. The specification states that it includes a housing, a rotating shaft, a push rod, a guide mechanism, and a rotating assembly. The housing contains two equal-strength beams, each with a strain grating. The two strain gratings are connected in series via optical fibers and linked to a fiber optic demodulator. The rotating shaft passes through the housing and is rotatably connected to it. A sleeve is perpendicularly connected to the rotating shaft. A gear is mounted on the rotating shaft. A rack is mounted on the push rod, meshing with the gear. Both ends of the push rod are connected to the two equal-strength beams. The free end of the beam is in contact; the guide mechanism is connected to the push rod and is used to guide the push rod to move linearly from one side wall of the housing to the other side wall in a direction perpendicular to the axis of rotation; one end of the rotating assembly is fixed and can rotate around that end; the other end is movably inserted into the sleeve rod and is used to drive the rotating shaft to rotate around its own axis so that the gear drives the push rod to reciprocate. This application has the advantages of long-term reliability and stability. However, in actual use, it still lacks a protective structure for the sensor in complex environments and it is difficult to alarm and correct when the sensor is deviated due to external factors.

[0004] While existing testing equipment undergoes initial debugging and calibration after installation, it generally lacks a long-term, effective stability guarantee mechanism. This makes it difficult for sensors to consistently and stably output accurate test data under different environmental conditions. Moreover, after installation, sensors are mostly simply fixed by external equipment without a specially designed protective structure to resist external interference factors such as vibration and impact. In practical applications, this lack of stability directly negatively impacts the reliability of test results, easily leading to misjudgments or missed judgments, thus posing a hidden danger to production safety. When the equipment is subjected to vibration or other external factors, the sensor is prone to synchronous vibration, causing distortion of the test data. More seriously, excessive vibration not only interferes with the detection but may also damage the internal structure of the sensor, significantly shortening its service life and threatening the safety of equipment use. Summary of the Invention

[0005] This invention provides a sensor-based displacement monitoring device and automatic alarm method, which solves the problems of existing detection equipment that only performs preliminary debugging and calibration after installation, lacks long-term stability assurance, and whose sensor installation often relies on simple external fixation without dedicated protective structures to resist external interference, resulting in poor stability in different environments, easy distortion of detection data, misjudgment and missed detection, threatening production safety, and may also damage the internal structure of the sensor and affect its service life.

During the monitoring process, if the sensor vibrates or becomes loose due to vibration or other external factors, the clamping blocks will reinforce the sensor. When the sensor shifts, it will push one clamping block, causing the other clamping block to loosen. At this time, the air pressure in the areas separated by partition plates within at least two sealing rings will change, triggering the pressure sensor and issuing an alarm. First, the device relies on two sets of mounting structures for fixation, ensuring the stability of the clamping blocks and enabling them to provide initial reinforcement to the sensor. When the sensor becomes loose and shifts, the positions of at least two clamping blocks will change, causing a change in the air pressure within the separated sealing rings, thus confirming the sensor's position shift. When only one partition area experiences a gas change, the device will not issue an alarm. This design improves the accuracy of the sensor monitoring data, providing immediate data alarms and preventing data distortion due to sensor shift or interference, while also ensuring the device's service life.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please refer to the following: Figures 1 to 9 The sensor-based displacement monitoring device and automatic alarm method include a positioner 21 and a sensor 22, and also include: The monitoring mechanism 1 includes a protective component 11, a monitoring component 12 housed within the protective component 11, a one-way control valve 13 and a pressure sensor 14 connected to the monitoring component 12, two connecting shells 15 connected to the protective component 11, two limiting components 16 and two adjusting components 17 connected to the two connecting shells 15, two docking components 18 and two adsorption components 19, wherein the two docking components 18 are respectively connected to the two connecting shells 15, and the two adsorption components 19 are respectively connected to the two connecting shells 15; and a sensor mechanism 2, including a positioner 21 and a sensor 22, wherein one end of the positioner 21 is connected to the sensor 22. After the monitoring component 12 is installed outside the sensor 22, the sensor 22 can be monitored. During the monitoring process, if the sensor 22 vibrates or becomes loose due to vibration or other external factors, the clamping block 127 will reinforce the sensor 22. When the sensor 22 shifts, The pressure sensor 14 will be triggered and an alarm will be issued because the device will push one of the clamping blocks 127, causing the other clamping block 127 to loosen. At this time, the air pressure in the area separated by the partition plate in at least two sealing rings 121 will change. The device is fixed by two sets of mounting structures to ensure the stability of the clamping blocks 127, so that the clamping blocks 127 can play a preliminary role in reinforcing the sensor 22. When the sensor 22 becomes loose and shifts, the position of at least two clamping blocks 127 will change, causing the air pressure in the sealed ring 121 after the partition to change, thus determining that the position of the sensor 22 has shifted. When the gas in only one partition area changes, the device will not issue an alarm. This design improves the accuracy of the device's monitoring data of the sensor 22, can provide data alarms in the first place, avoid the situation where the sensor 22 will cause the detection data to be distorted due to shift or interference, and also ensure the service life of the device.

[0021] The inner wall of the protective assembly 11 is fixedly connected to the monitoring assembly 12. The monitoring assembly 12 is connected to the one-way control valve 13 and the pressure sensor 14 respectively. Both the one-way control valve 13 and the pressure sensor 14 are located outside the protective assembly 11. The upper and lower parts of the protective assembly 11 are fixedly connected to two connecting shells 15 respectively. One side of the two connecting shells 15 is fixedly connected to two limiting components 16 and two docking components 18 respectively. The two limiting components 16 overlap with two adjusting components 17 respectively. The two protective assemblies 11 are fixedly connected to two adsorption components 19 respectively. One side of the positioner 21 is fixedly connected to the sensor 22. The outer wall of the sensor 22 overlaps with the inner wall of the monitoring assembly 12. Several clamping blocks 127 are pushed horizontally towards the sensor 22. The inclined grooves 128 of the clamping blocks 127 will gradually squeeze the slide rod 125 to retract it until the clamping blocks 127 are completely outside the sensor 22. At this time, the one-way control valve 13 is closed to prevent gas leakage. Then Pull the sealing cover 198 to make it fit against the wall or the surface of the installed steel beam. Then, rotate the knob 196 clockwise by 90 degrees. The rotation of the knob 196 drives the lead screw 194 to rotate. Under the action of the internal thread of the nut 195, the lead screw 194 pulls the sealing plate 192 to move. The sealing plate 192 will draw out the air between the sleeve expansion joint 197, the sealing cover 198 and the wall, so that a negative pressure is gradually formed between the three, and the adsorption and fixation are completed. After that, pull the limiting rod 167 to allow the connecting strip 166 to gradually extend and wrap around the steel beam once. Then, fasten the limiting rod 167 in the two limiting buckles 182 to complete the secondary fixation. In this way, the device can reinforce the sensor 22 for a second time. The device uses multiple fixing methods to work together to ensure that it can quickly adapt to different assembly environments and install the sensor 22 in place. It not only has the function of monitoring the sensor 22, but also reinforces the sensor 22, improving the safety of the sensor 22 during use.

[0022] The protective component 11 includes an outer ring 111, with a bushing 112 fitted onto the outer wall of the outer ring 111. One side of the outer ring 111 is fixedly connected to a fixed housing 113. The outer ring 111 is rotatably connected to two connecting housings 15 via the bushing 112. The monitoring component 12 is fixedly connected inside the outer ring 111. The monitoring component 12 includes a sealing ring 121, with several through holes 122 on the inner wall of the sealing ring 121. Several partition plates are provided inside the sealing ring 121, and sliding sleeves 123 are fixedly connected to each of the several through holes 122. A piston plate 124 and a sliding rod 125 are slidably connected inside the sliding sleeve 123. One side of the piston plate 124 is fixedly connected to one end of the sliding rod 125. A first spring 126 is fixedly fitted onto the outside of the sliding rod 125. The two ends of the first spring 126 are fixedly connected to one side of the inner wall of the sliding sleeve 123 and the piston plate 124, respectively. The other end of the slide rod 125 is fixedly connected to a clamping block 127. A slanted groove 128 is provided on one side of the clamping block 127. The clamping block 127 is snapped onto the outside of the sensor 22. A sealing ring 121 is fixedly connected to the inside of the outer ring 111. The sealing ring 121 is connected to the one-way control valve 13 and the pressure sensor 22 respectively. One side of the clamping block 127 is designed with an inclination. When installing the device, simply put the clamping block 127 on the outside of the sensor 22. At this time, the slanted surface of the clamping block 127 will directly contact the sensor 22. Under the action of the elastic force of the first spring 126, it can be ensured that the clamping block 127 fits tightly against the outside of the sensor 22. In this way, when the sensor 22 moves slightly or shifts, the device can issue an alarm immediately through the pressure sensor 14. This design reduces the assembly difficulty of the device and ensures its alarm effect.

[0023] The limiting assembly 16 includes a mounting shell 161. First bearings 162 are snapped onto the upper and lower sides of the inner wall of the mounting shell 161. A single rotating shaft 163 is sleeved within the two first bearings 162. A winding drum 164 is fixedly connected to the outside of the rotating shaft 163. A ratchet 165 is also fixedly connected to the outside of the rotating shaft 163. A connecting belt 166 is sleeved on the winding drum 164. The other end of the connecting belt 166 passes through the mounting shell 161 and is fixedly connected to a limiting rod 167. A coil spring 168 is sleeved on the rotating shaft 163. The other end of the coil spring 168 is fixedly connected to one of the first bearings 162. The mounting shell 161 is then fixed. Connected to the outside of the connecting shell 15, the adjusting assembly 17 includes a sleeve 171, a connecting rod 172 slidably connected inside the sleeve 171, a pawl 173 fixedly connected to the outside of the connecting rod 172, and a second spring 174 fixedly connected to the outside of the connecting rod 172. The other end of the second spring 174 is fixedly connected to the sleeve 171. The sleeve 171 is fixedly connected to the outside of the mounting shell 161. The pawl 173 overlaps the ratchet 165. After the connecting strap 166 is wrapped around the steel beam once and the limiting rod 167 is installed inside the limiting buckle 182, the connecting rod 172 needs to be squeezed to misalign the pawl 173 with the ratchet 165. At this time, the rotating shaft 163 will rotate rapidly under the action of the spring force of the coil spring 168, thereby winding up the excess length of the connecting strap 166 to ensure that the connecting strap 166 is tightly wrapped around the surface of the steel beam. Then, the connecting rod 172 is released, and the second spring 174 will drive it to reset, so that the ratchet 165 and the pawl 173 will re-engage, ensuring the stability of the device after installation and avoiding loosening that would affect the performance of the sensor 22.

[0024] The docking assembly 18 includes a mounting block 181, with two limiting buckles 182 fixedly connected to the top of the mounting block 181. The mounting block 181 is fixedly connected to one side of the connecting shell 15. The distance between the two limiting buckles 182 is greater than the width of the connecting strip 166 and less than the length of the limiting rod 167. The adsorption assembly 19 includes a sealing shell 191, with a sealing plate 192 slidably connected inside the sealing shell 191. A second bearing 193 is snapped onto one side of the sealing plate 192, and a lead screw 194 is sleeved inside the second bearing 193. The lead screw 194 has an external thread. A nut 195 is connected to the sealing shell 191. The other end of the screw 194 passes through the nut 195 and is fixedly connected to the knob 196. The other side of the sealing shell 191 is connected to the sleeve expansion joint 197, and the other side of the sleeve expansion joint 197 is connected to the sealing cover 198. The sealing shell 191 is fixedly connected to one side of the connecting shell 15. By adjusting the distance between the two limit buckles 182, it is ensured that when the limit rod 167 passes through the crossbeam at the installation position and is engaged in the limit buckle 182, the connecting belt 166 is positioned between the two limit buckles 182. This ensures that the limit rod 167 provides a good fixing effect to the limit buckle 182, preventing the limit rod 167 from loosening and falling off, thereby ensuring the stability of the device after installation.

[0025] The working principle of the sensor-based displacement monitoring device and automatic alarm method provided by this invention is as follows: In use, several clamping blocks 127 are pushed horizontally toward the sensor 22. The inclined grooves 128 of the clamping blocks 127 will gradually squeeze the slide rod 125 to retract until the clamping blocks 127 are completely fitted onto the outside of the sensor 22. At this time, the one-way control valve 13 is closed to prevent gas leakage. Then, the sealing cover 198 is pulled to fit against the wall or the surface of the installed steel beam. Then, the knob 196 is rotated 90 degrees clockwise. The rotation of the knob 196 drives the lead screw 194 to rotate. Under the action of the internal thread of the nut 195, the lead screw 194 pulls the sealing plate 192 to move. The sealing plate 192 draws out the air between the sleeve expansion joint 197, the sealing cover 198 and the wall, so that a negative pressure is gradually formed between the three to complete the adsorption and fixation. Finally, the limiting rod 167 is pulled to allow the connecting strip 166 to gradually extend and wrap around the steel beam once. Then, the limiting rod 167 is fastened in the two limiting buckles 182 to complete the fixation. After the monitoring component 12 is installed on the outside of the sensor 22, the sensor 22 can be monitored. During the monitoring process, if the sensor 22 vibrates or becomes loose due to vibration or other external factors, the clamping block 127 will reinforce the sensor 22. When the sensor 22 shifts, it will push the clamping block 127 on one side, which will cause the clamping block 127 on the other side to loosen. At this time, the air pressure in the area separated by the partition plate in at least two sealing rings 121 will change, and the pressure sensor 14 will be triggered and issue an alarm. First, the device is fixed by two sets of mounting structures, which ensures the stability of the clamping block 127 and enables the clamping block 127 to provide initial reinforcement for the sensor 22. When the sensor 22 becomes loose or shifts, the positions of at least two clamping blocks 127 will change, causing a change in the air pressure inside the sealing ring 121 after the partition, thus determining that the sensor 22 has shifted. However, when the air pressure changes in only one partition area, the device will not issue an alarm. After the connecting strip 166 is wrapped around the steel beam once and the limiting rod 167 is installed into the limiting buckle 182, the connecting rod 172 needs to be squeezed to misalign the pawl 173 with the ratchet 165. At this time, the rotating shaft 163 will rotate rapidly under the action of the spring 168, thereby winding up the excess length of the connecting strip 166 to ensure that the connecting strip 166 is tightly wrapped around the surface of the steel beam. Then, the connecting rod 172 is released, and the second spring 174 will drive it to reset, so that the ratchet 165 and the pawl 173 re-engage.

[0026] The present invention has the following effects: 1. After the monitoring component 12 is installed on the outside of the sensor 22, the sensor 22 can be monitored. During the monitoring process, if the sensor 22 vibrates or becomes loose due to vibration or other external factors, the clamping block 127 will reinforce the sensor 22. When the sensor 22 shifts, it will push one side of the clamping block 127, causing the other side of the clamping block 127 to loosen. At this time, the air pressure in the area separated by the partition plate within at least two sealing rings 121 will change, and the pressure sensor 14 will be triggered and issue an alarm. First, the device is fixed by two sets of mounting structures to ensure the clamping blocks are secure. The stability of clamping block 127 enables it to provide initial reinforcement for sensor 22. When sensor 22 becomes loose or shifts, the positions of at least two clamping blocks 127 will change, causing a change in the air pressure inside the sealing ring 121 after the partition, thus confirming that the position of sensor 22 has shifted. When only the gas in one partition area changes, the device will not issue an alarm. This design improves the accuracy of the device's monitoring data of sensor 22, provides data alarms in a timely manner, avoids data distortion caused by sensor 22 shifting or interference, and also ensures the service life of the device. 2. Push several clamping blocks 127 horizontally toward the sensor 22. The inclined grooves 128 of the clamping blocks 127 will gradually squeeze the slide rod 125 to retract it until the clamping blocks 127 are completely outside the sensor 22. At this time, close the one-way control valve 13 to prevent gas leakage. Then, pull the sealing cover 198 to make it fit against the wall or the surface of the installed steel beam. Then, rotate the knob 196 clockwise by 90 degrees. The rotation of the knob 196 drives the lead screw 194 to rotate. Under the action of the internal thread of the nut 195, the lead screw 194 pulls the sealing plate 192 to move. The sealing plate 192 will pull out the sleeve expansion joint 197 and seal. The air between the cover 198 and the wall gradually creates a negative pressure, completing the adsorption and fixation. Then, the limiting rod 167 is pulled, allowing the connecting strip 166 to gradually extend and wrap around the steel beam once. The limiting rod 167 is then fastened into the two limiting buckles 182 to complete the secondary fixation. In this way, the device can reinforce the sensor 22 a second time. The device uses multiple fixing methods in combination to ensure that it can quickly adapt to different assembly environments and install the sensor 22 in place. It not only has the function of monitoring the sensor 22, but also reinforces the sensor 22, improving the safety of the sensor 22 during use. 3. After wrapping the connecting strap 166 around the steel beam once and installing the limiting rod 167 into the limiting buckle 182, the connecting rod 172 needs to be squeezed to misalign the pawl 173 with the ratchet 165. At this time, the rotating shaft 163 will rotate rapidly under the action of the spring 168, thereby winding up the excess length of the connecting strap 166 and ensuring that the connecting strap 166 is tightly wrapped around the surface of the steel beam. Then, the connecting rod 172 is released, and the second spring 174 will drive it to reset, so that the ratchet 165 and the pawl 173 re-engage, ensuring the stability of the device after installation and avoiding loosening that would affect the performance of the sensor 22.
