A sensor assembly device and method thereof

Abstract

This invention belongs to the field of sensor assembly technology and discloses a sensor assembly device and method. The assembly device includes a magnetic levitation bearing with a fixing ring attached to its surface. Through the use of a magnetic block and a sensor, the operator only needs to attach the fixing ring to the magnetic levitation bearing. Then, the magnetic block inside the hollow column on the surface of the fixing ring moves towards the magnetic levitation bearing under the action of magnetic force, connecting the magnetic block and the magnetic levitation bearing.

Description

Technical Field

[0001] This invention belongs to the field of sensor assembly technology, specifically a sensor assembly device and method. Background Technology

[0002] Magnetic bearings are a new type of non-contact support device that uses electromagnetic force to suspend the rotor without contact, fundamentally overcoming the friction problem of mechanical bearings. They offer significant advantages such as no lubrication required, high speed, low power consumption, long lifespan, high precision, and active vibration control. However, magnetic bearings require real-time and precise detection of the magnetic levitation air gap, i.e., detecting the motion state of the rotor shaft, to achieve high-precision measurement. This necessitates the use of sensors to perform contact measurements on the magnetic bearing.

[0003] However, existing sensors require contact with the magnetic bearing during use. The typical method involves drilling a hole in the surface of the magnetic bearing, inserting the sensor into a mounting slot, and tightening the fasteners to position the sensor probe inside the slot, thus enabling monitoring of the magnetic bearing. However, this method has the following significant drawbacks:

[0004] 1. The device requires mounting grooves to be made on the magnetic levitation bearing, which increases the difficulty and cost of processing.

[0005] 2. This method requires the use of fasteners to fix the sensor, which increases the structural complexity and weight.

[0006] 3. This method cannot guarantee good contact between the sensor and the magnetic levitation bearing, which affects the sensitivity and stability of the sensor.

[0007] 4. This method cannot enable rapid replacement and adjustment of sensors, which reduces the maintainability and reliability of the system. Summary of the Invention

[0008] The purpose of this invention is to provide a sensor assembly apparatus and method to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a sensor assembly device and method, comprising a magnetic levitation bearing, a fixed ring attached to the surface of the magnetic levitation bearing, a hollow column fixedly connected to the end of the fixed ring away from the magnetic levitation bearing, a wireless transmitting module mounted on the surface of the fixed ring, a movable groove formed in the middle of the hollow column, a magnetic block movably connected inside the movable groove, a sliding groove formed on the inner wall of the movable groove, first sliders fixedly connected to both sides of the magnetic block, an insertion groove formed on the surface of the hollow column, a sensor mounted on one side of the hollow column, an annular contact platform fixedly connected to the bottom end of the sensor, a connecting rod fixedly connected to one side of the sensor, a second slider fixedly connected to the end of the connecting rod away from the sensor, an insertion rod fixedly connected to the surface of the second slider away from the connecting rod, and elastic connecting ropes connected to the inner wall of the second slider at the positions on both sides of the sliding groove.

[0010] As a further technical solution of the present invention, the slide groove is slidably connected to the first slider, and the second slider is slidably connected to the insertion groove.

[0011] The length of the groove is shorter than the length of the hollow column, which ensures that the magnetic block is inside the hollow column.

[0012] As a further technical solution of the present invention, the plug rod is inserted into the inside of the magnetic block, the wireless transmitting module and the external wireless receiving module are used in cooperation, and the wireless transmitting module and the sensor are connected.

[0013] During the movement of the magnetic block, the sensor is driven to move through the connection of the plug rod.

[0014] As a further technical solution of the present invention, the length of the slide groove is less than the length of the hollow column, and the distance between the bottom of the slide groove and the bottom of the hollow column is equivalent to the distance between the bottom of the first slider and the bottom of the magnetic block.

[0015] This ensures that the magnetic block is inside the hollow column and allows for easy removal of the magnetic block.

[0016] As a further technical solution of the present invention, the distance between the annular contact platform and the magnetic levitation bearing is equivalent to the movement distance of the first slider inside the movable groove, and the elastic connecting rope and the magnetic block are connected to each other.

[0017] The magnetic block and the magnetic levitation bearing move magnetically. At the same time, the cooperation between the slide and the first slider, as well as the cooperation between the elastic connecting rope and the magnetic block, can stabilize the fixed ring. During the movement of the magnetic block, the distance the magnetic block moves is the distance between the length of the slide and the length of the first slider, which is equivalent to the distance the plug rod moves, which is equivalent to the distance between the annular contact platform and the surface of the magnetic levitation bearing.

[0018] As a further technical solution of the present invention, the annular contact platform is adapted to the surface of the magnetic levitation bearing, and the wireless transmitting module and the wireless receiving module adopt any one or more of wireless communication protocols such as Bluetooth, WI-FI, NFC or RFID.

[0019] As a further technical solution of the present invention, the wireless receiving module is interconnected with an external device, which is any one or more smart terminals such as a computer, mobile phone, tablet computer or smartwatch.

[0020] As a further technical solution of the present invention, the magnetic block is adsorbed on the surface of the magnetic levitation bearing, and the sensor is one or more of a temperature sensor, vibration sensor, pressure sensor and displacement sensor.

[0021] The above-mentioned sensor assembly device and method include the following steps:

[0022] 1. First, attach the fixing ring to the surface of the magnetic levitation bearing so that the magnetic block moves by magnetic attraction;

[0023] The fixed ring is in contact with the surface of the magnetic levitation bearing, which means that the magnetic block and the magnetic levitation bearing move magnetically. At the same time, the cooperation between the slide groove and the first slider and the cooperation between the elastic connecting rope and the magnetic block can stabilize the fixed ring.

[0024] 2. The movement of the magnetic block causes the sensor to adhere to the surface of the magnetic levitation bearing via the annular contact platform;

[0025] The movement of the magnetic block drives the movement of the sensor, causing the annular contact platform to adhere to the surface of the magnetic levitation bearing, making it easier for the sensor to collect motion data of the magnetic levitation bearing through the annular contact platform.

[0026] 3. Connect the wireless transmission module to one or more sensors to enable the sensors to collect data from the magnetic levitation bearing;

[0027] The device's shape and status allow the wireless transmission module to connect to multiple sensors and simultaneously move the sensors. This is to facilitate the collection of the magnetic levitation bearing's status from multiple directions and then transmit it to the wireless transmission module.

[0028] 4. The wireless transmitting module sends data to the wireless receiving module in the form of wireless signals;

[0029] Wireless signals have a wide reception range and higher signal transmission efficiency in certain enclosed spaces.

[0030] 5. The wireless receiving module converts the wireless signal into an electrical signal and analyzes the state of the magnetic levitation bearing based on the electrical signal.

[0031] The use of electrical signals makes it easier for staff to intuitively record and analyze the status of magnetic levitation bearings.

[0032] The beneficial effects of this invention are as follows:

[0033] 1. This invention, through the design of a fixed ring, a magnetic levitation bearing, a magnetic block, and a sensor, allows the operator to simply attach the fixed ring to the magnetic levitation bearing. Then, the magnetic block inside the hollow column on the surface of the fixed ring moves towards the magnetic levitation bearing under magnetic force, connecting the magnetic block and the bearing. During the movement of the magnetic block, the sensor is driven to move via a connector rod, allowing the sensor to connect to the magnetic levitation bearing through a ring-shaped contact platform. This achieves sensor fixation without drilling holes in the magnetic levitation bearing surface, ensuring good contact between the sensor and the bearing, improving sensor sensitivity and stability, and allowing for quick disassembly and maintenance of the sensor and wireless transmission module.

[0034] 2. This invention fixes the wireless transmitting module to the magnetic levitation bearing and the wireless receiving module to an external device, enabling sensors to collect data from the magnetic levitation bearing and transmit the data to the wireless receiving module via the wireless transmitting module. This achieves wireless data transmission, improving system security and efficiency. Attached Figure Description

[0042] 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. Example 1

[0043] like Figures 1 to 5 As shown in the embodiment of the present invention, a sensor assembly device includes a magnetic levitation bearing 1, a fixing ring 2 attached to the surface of the magnetic levitation bearing 1, a hollow column 3 fixedly connected to the end of the fixing ring 2 away from the magnetic levitation bearing 1, a wireless transmitting module 4 mounted on the surface of the fixing ring 2, a movable groove 5 formed in the middle of the hollow column 3, a magnetic block 6 movably connected inside the movable groove 5, a sliding groove 7 formed on the inner wall of the movable groove 5, first sliders 8 fixedly connected to both sides of the magnetic block 6, an insertion groove 9 formed on the surface of the hollow column 3, a sensor 10 mounted on one side of the hollow column 3, an annular contact platform 11 fixedly connected to the bottom end of the sensor 10, a connecting rod 12 fixedly connected to one side of the sensor 10, a second slider 13 fixedly connected to the end of the connecting rod 12 away from the sensor 10, an insertion rod 14 fixedly connected to the surface of the second slider 13 away from the connecting rod 12, elastic connecting ropes 15 connected to the inner wall of the second slider 13 at the positions on both sides of the sliding groove 7, the sliding groove 7 and the first slider 8 are slidably connected, and the second slider 13 and the insertion groove 9 are slidably connected. Connecting rod 14 is inserted into the inside of magnetic block 6. Wireless transmitting module 4 and external wireless receiving module work together. Between wireless transmitting module 4 and sensor 10, the length of slide groove 7 is lower than the length of hollow column 3. The distance between the bottom of slide groove 7 and the bottom of hollow column 3 is equivalent to the distance between the bottom of first slider 8 and the bottom of magnetic block 6. The distance between annular contact platform 11 and magnetic levitation bearing 1 is equivalent to the movement distance of first slider 8 inside movable groove 5. Elastic connecting rope 15 is connected to magnetic block 6. Annular contact platform 11 is adapted to the surface of magnetic levitation bearing 1. Wireless transmitting module 4 and wireless receiving module adopt any one or more of wireless communication protocols such as Bluetooth, WI-FI, NFC or RFID. Wireless receiving module is connected to external device. External device is any one or more of smart terminal such as computer, mobile phone, tablet or smartwatch. Sensor 10 is one or more of temperature sensor, vibration sensor, pressure sensor and displacement sensor.

[0044] Compared with existing technologies, the advantages are as follows: When the device is in use, the operator only needs to attach the fixing ring 2 and the magnetic levitation bearing 1 together. Then, the magnetic block 6 inside the hollow column 3 on the surface of the fixing ring 2 moves towards the magnetic levitation bearing 1 under the action of magnetic force. At this time, the magnetic block 6 and the magnetic levitation bearing 1 are connected to each other. During the movement of the magnetic block 6, the sensor 10 is driven to move through the connection of the plug rod 14, so that the sensor 10 is connected to the magnetic levitation bearing 1 through the annular contact platform 11. Since the length of the slide groove 7 is lower than the length of the hollow column 3, it can be ensured that the magnetic block 6 is inside the hollow column 3, and the magnetic block 6 can be easily removed. During the movement of the magnetic block 6, the movement distance of the magnetic block 6 is the distance of the slide groove 7 minus the length of the first slider 8, which is equivalent to the movement distance of the plug rod 14, which is equivalent to the distance between the annular contact platform 11 and the surface of the magnetic levitation bearing 1. Example 2

[0047] The fixed ring 2 is in contact with the surface of the magnetic levitation bearing 1, which means that the magnetic block 6 and the magnetic levitation bearing 1 move magnetically. At the same time, the cooperation between the slide groove 7 and the first slider 8 and the cooperation between the elastic connecting rope 15 and the magnetic block 6 can stabilize the fixed ring 2.

[0048] Step 2: The movement of the magnetic block 6 causes the sensor 10 to adhere to the surface of the magnetic levitation bearing 1 through the annular contact platform 11;

[0049] The movement of the magnetic block 6 drives the sensor 10 to move, so that the annular contact platform 11 is in contact with the surface of the magnetic levitation bearing 1, making it easier for the sensor 10 to collect motion data of the magnetic levitation bearing 1 through the annular contact platform 11.

[0050] Step 3: Connect the wireless transmission module 4 to one or more sensors 10, so that the sensors 10 can collect data from the magnetic levitation bearing 1;

[0051] The device itself is shaped and in a state that allows the wireless transmission module 4 to be connected to multiple sensors 10 and to move the sensors 10 at the same time. The purpose is to facilitate the collection of the state of the magnetic levitation bearing 1 from multiple directions and then transmit it to the wireless transmission module 4.

[0052] Step 4: The wireless transmitting module 4 transmits data to the wireless receiving module in the form of wireless signals;

[0053] Wireless signals have a wide reception range and higher signal transmission efficiency in certain enclosed spaces.

[0054] Step 5: The wireless receiving module converts the wireless signal into an electrical signal and analyzes the state of the magnetic levitation bearing 1 based on the electrical signal.

[0055] The use of electrical signals makes it easier for staff to intuitively record and analyze the state of the magnetic levitation bearing 1.

[0056] Working principle and usage process: The fixing ring 2 and the magnetic levitation bearing 1 are attached to each other. The magnetic block 6 moves towards the magnetic levitation bearing 1 under the action of magnetic force. During the movement of the magnetic block 6, the sensor 10 is driven to move through the connection of the plug rod 14, so that the sensor 10 is connected to the magnetic levitation bearing 1 through the annular contact platform 11, collects the state of the magnetic levitation bearing 1, and then transmits it to the wireless transmission module 4. The wireless transmission module 4 sends the data to the wireless receiving module in the form of wireless signal. The wireless receiving module converts the wireless signal into an electrical signal and analyzes the state of the magnetic levitation bearing 1 based on the electrical signal.
