Description

Technical Field

[0001] This invention relates to the field of data acquisition device technology, specifically to a data acquisition device based on the Industrial Internet. Background Technology

[0002] Industrial Internet-based data acquisition devices are intelligent front-end acquisition devices that connect to field equipment or tanks, sense production data, and then upload it to a cloud platform. For example, one device integrates online temperature measurement of liquids in tanks: by deploying immersion temperature probes inside the storage tank, it accurately collects the actual temperature of the liquid inside. The collected temperature signal is then converted via protocol by the local acquisition module and the industrial edge gateway, and uploaded to the industrial Internet platform in real time. This enables real-time temperature data monitoring, curve storage, over-limit alarms, and traceability linked to production batches.

[0003] When the tank is heated by external wall tracing and insulation, heat is conducted radially from the tank wall to the center. Within the same horizontal liquid layer, the temperature is higher at the edge of the tank wall and lower in the central area, resulting in a radial temperature difference. However, conventional fixed temperature detectors are only deployed at a single point in the center of the tank, which cannot capture the true high-temperature range on the tank wall. The sampled data is biased towards the mean and cannot fully characterize the overall liquid temperature inside the tank. This can easily lead to problems such as temperature measurement lag, inaccurate temperature control compensation, and difficulty in detecting local material temperature anomalies. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an industrial internet-based data acquisition device, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an industrial internet-based data acquisition device, comprising a top plate and a connecting block fixedly connected to the bottom of the top plate. A motor is fixedly installed on the side wall of the connecting block. A connecting strip and a pulley are fixedly connected to the output end of the motor. A rotating shaft is rotatably inserted at the end of the connecting strip away from the connecting block. A temperature sensor is fixedly connected to the rotating shaft. A cylindrical block is fixedly connected to one end of the rotating shaft. A groove is formed on the connecting strip. A slider is slidably arranged inside the groove. A spring is fixedly connected between the slider and the inner wall of the groove. An arc-shaped pressure block is fixedly connected to the end of the slider. A connecting rod is fixedly connected to the arc-shaped pressure block. An arc-shaped pressure block is fixedly connected to the other end of the connecting rod. The arc-shaped pressure block and the arc-shaped pressure block intermittently abut against the circumferential side wall of the cylindrical block. A traction rope is wound around the pulley, and the other end of the traction rope is fixedly connected to the slider.

[0006] Preferably, a connecting strip two is fixedly connected to the bottom of the top plate, an L-shaped guide rod is movably inserted on the connecting strip two, a guide block is fixedly connected to the other end of the rotating shaft one, and the other end of the L-shaped guide rod movably passes through the guide block.

[0007] Preferably, the temperature sensor is always positioned vertically, and the lower end of the temperature sensor is a probe.

[0008] Preferably, the groove is a T-groove and the slider is a T-block.

[0009] Preferably, a distance measuring component is provided between the top of the top plate and the pulley, and the distance measuring component is used to calculate the lateral displacement of the temperature sensor.

[0010] Preferably, the distance measuring component includes a support block fixedly mounted on the top of the top plate, a second rotating shaft rotatably inserted into the side wall of the support block, a third pulley fixedly connected to the other end of the second rotating shaft, a second pulley coaxially fixedly connected to the second pulley, a scale belt fixedly connected between the second pulley and the third pulley, a torsion spring fixedly connected between the support block and the third pulley, and a through-hole provided on the top plate through which the scale belt passes.

[0011] Preferably, a horizontal pointer is fixedly connected to the side wall of the support block, and the pointer points to the scale mark on the scale.

[0012] Preferably, the surface of the top plate has multiple through holes that are evenly distributed.

[0013] This invention provides a data acquisition device based on the Industrial Internet, which has the following beneficial effects: 1. In this invention, the temperature sensor is moved from the center of the tank to the edge of the tank wall, so as to realize the dynamic adjustment of the detection point and the temperature measurement range; at the same time, it can collect gradient temperature data of the low temperature zone in the center and the high temperature zone at the edge in real time, which makes up for the shortcomings of traditional fixed center temperature measurement that can only sample at a single point and cannot characterize the radial temperature difference.

[0014] 2. In this invention, the lateral displacement of the temperature sensor can be measured and located in real time by the distance measuring component, accurately feeding back the actual radial travel position of the sensor from the center to the edge of the tank; combined with the real-time temperature of the corresponding point, the gradient temperature distribution of the low-temperature zone in the center and the high-temperature zone at the edge can be calibrated simultaneously; the measured position data and temperature measurement data are connected to the industrial Internet acquisition device, making temperature control compensation, temperature difference analysis, and anti-caking temperature control more accurate and controllable.

[0015] 3. In this invention, when the temperature sensor is at the center, the traction rope pulls the arc-shaped pressure block two, causing the arc-shaped pressure block two to come into contact with the cylindrical block; when the temperature sensor is at the edge of the tank wall, the arc-shaped pressure block one comes into contact with the cylindrical block under the action of the spring; the purpose of both is to press the cylindrical block tightly, that is, to lock the position of the temperature sensor and ensure the stability of the temperature sensor in the fluid environment.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] Please see Figures 1 to 7This invention provides a technical solution: an industrial internet-based data acquisition device, comprising a top plate 1, a connecting block 2 fixedly connected to the bottom of the top plate 1, a motor 3 fixedly mounted on the side wall of the connecting block 2, a connecting strip 4 and a pulley 5 fixedly connected to the output end of the motor 3, a rotating shaft 15 rotatably inserted at the end of the connecting strip 4 away from the connecting block 2, a temperature sensor 12 fixedly connected to the rotating shaft 15, a cylindrical block 13 fixedly connected to one end of the rotating shaft 15, and a groove opened on the connecting strip 4. The slide 401 has a slider 8 slidably mounted inside it. A spring 7 is fixedly connected between the slider 8 and the inner wall of the slide 401. An arc-shaped pressure block 9 is fixedly connected to the end of the slider 8. A connecting rod 10 is fixedly connected to the arc-shaped pressure block 9. An arc-shaped pressure block 11 is fixedly connected to the other end of the connecting rod 10. The arc-shaped pressure block 11 and the arc-shaped pressure block 9 intermittently abut against the circumferential side wall of the cylindrical block 13. A traction rope 6 is wound around the pulley 5. The other end of the traction rope 6 is fixedly connected to the slider 8.

[0020] Start motor 3, which drives connecting bar 4 to swing clockwise around the output end of motor 3, so that the temperature sensor 12, which is hinged at one end of connecting bar 4, is moved from the center of tank 25 to the edge of tank wall. At this time, due to the gravity of temperature sensor 12 and the fact that temperature sensor 12 is hinged to connecting bar 4 through rotating shaft 15, temperature sensor 12 is always in a vertical state.

[0021] That is, the temperature sensor 12 is moved from the center of the tank 25 to the edge of the tank wall, so that the detection point and temperature measurement range can be dynamically adjusted; at the same time, it can collect gradient temperature data of the low temperature zone in the center and the high temperature zone at the edge in real time, which makes up for the shortcomings of traditional fixed center temperature measurement which can only sample at a single point and cannot characterize radial temperature difference.

[0022] Furthermore, when the temperature sensor 12 is at the center, the traction rope 6 pulls the arc-shaped pressure block 11, causing the arc-shaped pressure block 11 to come into contact with the cylindrical block 13; when the temperature sensor 12 is at the edge of the tank wall, the arc-shaped pressure block 9 comes into contact with the cylindrical block 13 under the action of the spring 7; the purpose of both is to press the cylindrical block 13 tightly, that is, to lock the position of the temperature sensor 12, and to ensure the stability of the temperature sensor 12 in the fluid environment.

[0023] Reference Figure 1 and Figure 2 The top plate 1 has a connecting strip 2 17 fixedly connected to its bottom. An L-shaped guide rod 16 is movably inserted into the connecting strip 2 17. The other end of the rotating shaft 15 is fixedly connected to a guide block 14. The other end of the L-shaped guide rod 16 is movably inserted through the guide block 14.

[0024] During the movement of the temperature sensor 12 with the mechanism, the guide block 14 can move vertically relative to the L-shaped guide rod 16, and the L-shaped guide rod 16 slides laterally along the connecting strip 17 in the horizontal direction, thereby guiding and limiting the movement path of the temperature sensor 12, and the temperature sensor 12 is set in a vertical state; ensuring that the temperature sensor 12 moves smoothly and without jamming during the translation from the center of the tank 25 to the edge, ensuring stable and reliable radial temperature detection, and preventing the temperature sensor 12 from accidentally swinging and scraping against the inner wall of the tank 25.

[0025] Reference Figure 1 The temperature sensor 12 is always positioned in a vertical direction, and the lower end of the temperature sensor 12 is the probe 1201.

[0026] The temperature sensor 12 is always arranged vertically, and its lower end is equipped with a downward-extending probe 1201 for immersing in the liquid in the tank 25 for temperature detection. The temperature sensor 12 is an existing mature product and can communicate with an external Internet of Things platform for network communication and data upload.

[0027] Reference Figure 1 The slide 401 is a T-slot, and the slider 8 is a T-block.

[0028] The two slide together, and the slider 8 moves relatively linearly along the groove 401, which can effectively prevent the slider 8 from coming out of the groove 401 during the movement, ensuring smooth and reliable transmission.

[0029] Reference Figure 1 A distance measuring component is provided between the top of the top plate 1 and the pulley 5. The distance measuring component is used to calculate the lateral displacement of the temperature sensor 12.

[0030] The lateral displacement of temperature sensor 12 can be measured and located in real time by the distance measuring component, accurately feeding back the actual radial travel position of the sensor from the center to the edge of tank 25; combined with the real-time temperature of the corresponding point, the gradient temperature distribution of the low temperature zone in the center and the high temperature zone at the edge can be calibrated simultaneously; the calculated position data and temperature measurement data are connected to the industrial Internet acquisition device, making temperature control compensation, temperature difference analysis, and anti-caking temperature control more accurate and controllable.

[0031] Reference Figure 1The distance measuring component includes a support block 21 fixedly mounted on the top of the top plate 1, a rotating shaft 23 rotatably inserted into the side wall of the support block 21, a pulley 20 fixedly connected to the other end of the rotating shaft 23, a pulley 18 coaxially fixedly connected to the pulley 1, a scale belt 19 fixedly connected between the pulley 18 and the pulley 20, a torsion spring 24 fixedly connected between the support block 21 and the pulley 20, and a through opening 101 on the top plate 1 through which the scale belt 19 passes. The purpose is to allow the scale belt 19 to pass through the top plate 1 smoothly and avoid interference with the top plate 1, so as to ensure that the distance measuring component can normally measure the horizontal displacement of the temperature sensor 12.

[0032] The following explains the distance measuring principle: Motor 3 drives pulley 5 and pulley 18 to rotate clockwise. Pulley 18 winds up the scale belt 19 and pulls the scale belt 19 to release it from pulley 20. The torsion spring 24 then generates torsional force. The difference between the readings of the initial state and the end state on the scale belt 19 is the horizontal displacement length corresponding to the temperature sensor 12.

[0033] When motor 3 drives pulley 5 and pulley 18 to rotate counterclockwise (causing temperature sensor 12 to move from the edge to the center, i.e., to perform a reset motion), torsion spring 24 releases torque, pulling pulley 20 to rotate counterclockwise. Pulley 20 then winds up the scale tape 19, achieving a reset.

[0034] Reference Figure 4 A horizontal pointer 22 is fixedly connected to the side wall of the support block 21. The pointer 22 points to the scale mark on the scale 19, which makes it easy to read the displacement value intuitively. The difference between the readings of the initial state and the final state is the horizontal displacement length corresponding to the temperature sensor 12.

[0035] Reference Figure 7 The surface of the top plate 1 has multiple through holes 102 that are evenly distributed.

[0036] It should be noted that this device is fixedly installed inside the tank 25, and the inner wall of the tank 25 is embedded with a heating coil. The top plate 1 is used to be fixedly installed on the top of the tank 25. The diameter of the top plate 1 is larger than the opening at the top of the tank 25. The temperature sensor 12, the connecting strip 4 and other components are inserted into the tank 25 through this opening. However, the top plate 1 will not enter due to its large area. The surface of the top plate 1 has multiple equally spaced through holes 102. The top plate 1 is fixedly installed on the top of the tank 25 by using fasteners.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
