Description

Technical Field

[0001] The present invention relates to the technical field of displacement sensors, and in particular to a Bluetooth cloud-based horizontal displacement sensor. Background Art

[0002] The Bluetooth cloud-based horizontal displacement sensor is a sensor system that combines Bluetooth technology and cloud processing capabilities. It is mainly used to measure the horizontal displacement of an object and transmit the data to the cloud for analysis and processing. The Bluetooth cloud-based horizontal displacement sensor system mainly includes the following parts: Displacement sensor module: This is the core part of the system and is responsible for data acquisition of field signals. It uses a specific measurement principle (such as inductive, capacitive, photoelectric or Hall, etc.) to convert the horizontal displacement change of an object into an electrical signal or other form of signal output. Bluetooth wireless module: This module runs the Bluetooth wireless communication protocol, allowing the displacement sensor device to meet the Bluetooth wireless communication protocol specification. It is responsible for wirelessly transmitting the data collected by the sensor to a device with Bluetooth receiving function, such as a smartphone, tablet or a dedicated Bluetooth receiver. Cloud processing platform: Receives data from the Bluetooth wireless module and performs further processing and analysis. The cloud platform has powerful data processing and storage capabilities, and can display displacement data in real time, perform trend analysis, and even trigger early warning and alarm functions.

[0003] Among them, the horizontal displacement sensor involved in the displacement sensor module is also called a linear sensor. It is a linear device belonging to metal induction. The function of the sensor is to convert various measured physical quantities into electrical quantities. The most typical one is the magnetostrictive displacement sensor. The magnetostrictive displacement sensor uses non-contact measurement and control technology to accurately detect the absolute position of the active magnetic ring to measure the actual displacement value of the detected product. It has the advantages of high precision and strong reliability, and is therefore widely used in various fields.

[0004] However, magnetostrictive displacement sensors still have many defects. For example, the measuring element in the magnetostrictive displacement sensor is a waveguide tube. The measurement process is that a current pulse is generated in the electronic room of the sensor. The current pulse is transmitted in the waveguide tube, thereby generating a circumferential magnetic field outside the waveguide tube. When the magnetic field intersects with the magnetic field generated by the active magnetic ring that is mounted on the waveguide tube as a position change, a strain mechanical wave pulse signal is generated in the waveguide tube due to the effect of magnetostriction. This strain mechanical wave pulse signal is transmitted at a fixed sound speed and is quickly detected by the electronic room. However, the magnetic field generated by this process will produce a certain gravitational force on the medium in the inner cavity of the device. As the external magnetic ring stretches back and forth along the outside of the waveguide tube, the medium will be adsorbed on the outer wall of the waveguide tube. When the working area of ​​the device is humid or there is an oily environment, the attached medium will accelerate the corrosion of the waveguide tube. At the same time, as the amount of medium increases, it will also cause interference to the magnetic field between the waveguide tube and the magnetic ring.

[0005] In view of this, the present invention designs a Bluetooth cloud-based horizontal displacement sensor to solve the above problems. Summary of the invention

[0045] To make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in combination with specific implementations and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0046] It is to be understood that these descriptions are exemplary only and are not intended to limit the scope of the invention.

[0047] A Bluetooth cloud-based horizontal displacement sensor provided by some embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0048] Embodiment 1:

[0049] Combination Figure 1-Figure 10As shown, a Bluetooth cloud-based horizontal displacement sensor provided by the present invention includes a sensor assembly 500 and a ranging magnetic ring 300, a pressure-resistant calibration mechanism 100 installed on the sensor assembly 500, a distance-fixed anti-slip mechanism 400 installed on the ranging magnetic ring 300, and a tube protection mechanism 200 arranged on the sensor assembly 500. The ranging magnetic ring 300 is non-contact reciprocatingly extended along the outside of the protective tube 230, and the sensor assembly 500 is used to perform horizontal distance measurement on the reciprocatingly extended ranging magnetic ring 300.

[0050] The pressure-resistant calibration mechanism 100 includes a clamping seat 110, a first beam 120, a second beam 130, a bracket 140, a buckle 150, a base 160 and a support rod 170. The tube body protection mechanism 200 includes a waterproof base 210, a first sealing ring 220, a protective tube 230, a limiting gasket 240, a sealing end 250 and a second sealing ring 260. The fixed-distance anti-slip mechanism 400 includes an adapter 410, an outer frame 420, a splint 430, a pressure-resistant inclined frame 440, an elastic reset assembly 450 and a scraper head 460. The sensor assembly 500 includes a detection assembly 510 and a waveguide tube 520.

[0051] The compression calibration mechanism 100 includes a ring buckle 150, two brackets 140 mounted on the ring buckle 150, a first beam rod 120 mounted in one of the brackets 140, and a second beam rod 130 mounted in the other bracket 140;

[0052] The tube protection mechanism 200 includes a protection tube 230 disposed inside the ring buckle 150, a limiting gasket 240 fixedly mounted on the protection tube 230, and a sealing end 250 mounted on the outer end of the protection tube 230;

[0053] The cross-sections of the ring buckle 150 and the limiting gasket 240 are both L-shaped structures;

[0054] The ring buckle 150 and the limiting washer 240 are both made of stainless steel;

[0055] The fixed distance anti-slip mechanism 400 includes four scraping heads 460 attached to the outer wall of the protective tube 230, a pressure-resistant inclined frame 440 movably connected to the scraping heads 460, and an outer frame 420 movably connected to the other end of the pressure-resistant inclined frame 440;

[0056] A guide rod is installed in the middle of the compression-resistant inclined frame 440;

[0057] The sensor assembly 500 includes a detection assembly 510 mounted inside the clamping seat 110 and a waveguide 520 mounted on the detection assembly 510;

[0058] The waveguide tube 520 is disposed in the middle of the inner cavity of the protective tube 230 , and the end of the sealing end 250 that penetrates into the inner cavity of the protective tube 230 is adapted and pressed against the outer end of the waveguide tube 520 .

[0059] The magnetostrictive displacement sensor uses the magnetostrictive principle to accurately measure the position by generating a strain pulse signal through the intersection of two different magnetic fields.

[0060] The measuring element is a waveguide, and the sensitive element in the waveguide is made of special magnetostrictive material;

[0061] The measurement process is that a current pulse is generated in the electronic room of the sensor, and the current pulse is transmitted in the waveguide, thereby generating a circumferential magnetic field outside the waveguide. When the magnetic field intersects with the magnetic field generated by the active magnetic ring that is mounted on the waveguide as a position change, a strain mechanical wave pulse signal is generated in the waveguide due to the effect of magnetostriction. This strain mechanical wave pulse signal is transmitted at a fixed sound speed and is quickly detected by the electronic room. However, when the external magnetic ring is stretched along the outside of the waveguide without contact, it is affected by the magnetic field. The medium molecules in the device are affected by the magnetic field and the humid and oily environment and will be adsorbed on the outer wall of the waveguide. As the medium increases, the waveguide made of traditional stainless steel rods will be corroded, and the reciprocating stretching of the device's test components and the magnetic ring will gradually cause reset errors, which will lead to errors in the device's distance measurement, and in severe cases, the device will be damaged.

[0062] When the device is in use, a non-contact protective tube 230 is arranged outside the waveguide 520, and a sealing end 250 is installed at the outer end of the protective tube 230. At this time, the sealing end 250 penetrates into the end of the inner cavity of the protective tube 230 to position and press the outer end of the waveguide 520, and the clamping seat 110 fixed on the outside of the detection component 510 can provide calibration and pressure protection for the first beam 120 and the second beam 130. As the distance measurement component in the device drives the adapter 410 and the distance measurement magnetic ring 300 along the protective tube 2 When the protective tube 230 is extended back and forth, the four scraping heads 460 attached to the outer wall of the protective tube 230 can scrape off the adhered medium under pressure, and the scraping heads 460 are in contact with the protective tube 230 over a large area, so the four scraping heads 460 under balanced pressure will not cause extrusion damage to the protective tube 230. At the same time, through the bidirectional constraints of the four scraping heads 460 by the ring buckle 150 and the limit washer 240, the components to be measured in the device can avoid the occurrence of errors in the distance measurement value of the sensor component 500 due to long-term operation exceeding the reset distance.

[0063] Embodiment 2:

[0064] Combination Figure 2-Figure 8As shown, based on Example 1, the compression calibration mechanism 100 further includes a clamping seat 110 disposed in the first beam 120 and the second beam 130, a base 160 disposed between the first beam 120 and the second beam 130, and four support rods 170 mounted on the base 160;

[0065] A nut is provided on the threaded section of the support rod 170 .

[0066] A plurality of evenly distributed feet are installed on the inner side of the base 160 , and through holes are formed in the feet, and locking bolts are disposed in the through holes.

[0067] The waterproof base 210 is inserted into the four support rods 170, and the waterproof base 210 is pressed and fixed on the four support rods 170 by four nuts. When the four support rods 170 and the base 160 are assembled and fixed on the end of the detection component 510 by bolts, the compressed waterproof base 210 can cooperate with the first sealing ring 220 to press the protective tube 230 on the detection component 510. As the sealing end 250 seals the other end of the protective tube 230, the waveguide 520 can be located in the middle of the inner cavity of the protective tube 230 for operation. At this time, the waveguide 520 in a hollow protection state can avoid corrosion caused by external media. At the same time, the first beam 120 and the second beam 130 movably installed in the clamp seat 110 can cooperate with the extension of the ring buckle 150 and the two brackets 140 to provide calibration and pressure protection.

[0068] Embodiment 3:

[0069] Combination Figure 2-Figure 10 As shown, based on the embodiment 1, the tube protection mechanism 200 further includes a waterproof base 210 installed at the other end of the protection tube 230 and a first sealing ring 220 arranged in the inner ring groove of the waterproof base 210;

[0070] The waterproof base 210 is provided with four end plates distributed in a cross shape on the outside, and the end plates are provided with insertion holes inside, the threaded sections of the base 160 are adapted to penetrate into the insertion holes, and the nuts are pressed tightly on the end plates;

[0071] The waterproof base 210 and the sealing end 250 are both made of ceramic material;

[0072] Two grooves are formed on the tube wall of the threaded end tube of the sealing end head 250, and a second anti-seepage sealing ring 260 is arranged in the groove.

[0073] When the sealing end head 250 is threadedly installed in the screw hole at the end of the protective tube 230 away from the waterproof base 210, as the sealing end head 250 is fixed, the two second sealing rings 260 arranged on the sealing end head 250 can press the tube wall of the protective tube 230. At this time, the inner cavity of the combined protective tube 230 and the sealing end head 250 can maintain a clean and dry environment. At this time, the waveguide tube 520 horizontally placed in the middle of the protective tube 230 can be safely used in a corrosion-free state, and the limiting gasket 240 fixedly installed on the protective tube 230 can provide the four evenly distributed scrapers 460 with anti-reset over-distance problems.

[0074] Embodiment 4:

[0075] Combination Figure 5-Figure 10 As shown, in the above embodiment, the distance-fixing anti-slip mechanism 400 further includes an adapter 410 clamped on the distance-measuring magnetic ring 300 and four outer frames 420 fixedly mounted on the adapter 410;

[0076] The outer frame 420 is composed of an L-shaped bracket and an arc-shaped end plate, and the other end of the compression-resistant oblique frame 440 is connected to the outer end of the L-shaped bracket through a guide rod;

[0077] The fixed distance anti-slip mechanism 400 also includes an elastic reset assembly 450 and a clamping plate 430 mounted on an L-shaped bracket inside the outer frame 420;

[0078] The elastic reset assembly 450 is composed of a telescopic mother tube, a telescopic sub-rod and a spring, and the outer end of the telescopic sub-rod is movably mounted on the guide rod, and the outer end of the telescopic mother tube is movably mounted on the clamping plate 430;

[0079] The scraper head 460 has a notch on its exterior adapted to the ring buckle 150, and a blade for scraping off the medium on the surface of the protective tube 230 is formed at one end of the scraper head 460 away from the pressure-resistant inclined frame 440;

[0080] A slot adapted to the limiting washer 240 is formed at the bottom of the scraper head 460 .

[0081] The adapter 410 is fixedly installed on the component to be measured by the device by using multiple sub-bolts. As the component to be measured drives the adapter 410 and the distance measuring magnetic ring 300 to extend at a uniform speed, the distance measuring magnetic ring 300 along the outside of the protective tube 230 and without contact can cooperate with the sensor component 500 for real-time detection, and the four scraping heads 460 that are pressed and moved laterally can scrape the medium on the wall of the protective tube 230. While ensuring the cleanliness of the wall of the protective tube 230, it can reduce the blockage of the movement of the distance measuring magnetic ring 300 caused by excessive accumulation of the medium. At the same time, the four evenly distributed scraping heads 460 can be doubly positioned by the limiting gasket 240 and the ring buckle 150. Once the distance measuring magnetic ring 300 is reset beyond the specified distance, the positioned scraping heads 460 can prevent the protective tube 230 from being partially squeezed and damaged.

[0082] The working principle and use process of the present invention are as follows: the detection component 510 is pre-installed in the specified device, and the distance measuring magnetic ring 300 is installed on the component of the device to be tested by using the adapter 410, and the protective tube 230 is arranged on the outside of the waveguide tube 520. At this time, the waveguide tube 520 has no direct contact with the inner wall of the protective tube 230, and the two second sealing rings 260 and the sealing end head 250 are installed at the outer end of the protective tube 230. At this time, the combined protective tube 230 and the sealing end head 250 can be sealed and pressed with the outer end of the detection component 510, and the waterproof base 210 will be fixed by the nuts on the four support rods 170. At this time, the waveguide tube 520 can operate safely in an acid-free and alkali-free environment. Since the distance measuring magnetic ring 300 has no direct contact with the protective tube 230 and the sealing end head 250, the distance measuring magnetic ring 300 reciprocates along the outside of the protective tube 230. When the distance measuring magnetic ring 300 moves laterally, the circumferential magnetic field formed by the distance measuring magnetic ring 300 will adsorb part of the medium on the surface of the protective tube 230. As the medium on the surface of the protective tube 230 increases, the outer wall of the protective tube 230 will become dirty. As the distance measuring magnetic ring 300 reciprocates along the protective tube 230, the adapter 410 installed on the outside of the distance measuring magnetic ring 300 will cooperate with the four outer frames 420 to move at the same speed, and combined with the traction of the four pressure-resistant inclined frames 440 by the four sets of elastic reset components 450, the four scraping heads 460 movably installed on the four pressure-resistant inclined frames 440 can be pulled and adapted to fit on the outer wall of the protective tube 230. After the adapter 410 is stretched at a uniform speed, the blades of the four pulled scraping heads 460 will scrape off the medium on the outer wall of the protective tube 230, thereby reducing the influence of the increase of the medium on the magnetic field around the distance measuring magnetic ring 300;

[0083] At the same time, the protective tube 230 and the sealing end 250 arranged on the outside of the waveguide tube 520 can prevent the external medium from entering and provide anti-corrosion protection for the waveguide tube 520. The limiting gasket 240 and the ring buckle 150 can lock and constrain the four scraper heads 460 while preventing the scraper heads 460 from detaching from the surface of the protective tube 230 due to the ranging magnetic ring 300 exceeding the reset distance. At this time, the clamp seat 110 will provide pressure-bearing protection for the first beam 120 and the second beam 130. Once the ranging magnetic ring 300 exceeds the specified distance and causes compressive force on the protective tube 230, the first beam 120 and the second beam 130 symmetrically distributed on both sides of the protective tube 230 can provide pressure protection for the protective tube 230, thereby preventing the protective tube 230 from being damaged due to excessive stretching of the ranging magnetic ring 300, which in turn causes excessive squeezing force on the protective tube 230 by the scraper heads 460.

[0084] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
