Description

Technical Field

[0001] This application relates to the field of intelligent sensing equipment technology, specifically to liquid level measurement scenarios in the industrial internet context, and particularly to a water level measurement device for supercritical water storage tanks. Background Technology

[0002] Intelligent sensing devices are the core sensing nodes for data acquisition and system security monitoring in the industrial internet system. Among them, liquid level measurement intelligent sensors are key components for the operation and maintenance of industrial liquid storage equipment and need to be adapted to different working conditions and functional requirements.

[0003] In supercritical operating scenarios of related technologies, water level monitoring of water storage tanks places extremely high demands on the temperature and pressure resistance, as well as the anti-interference performance of intelligent sensing devices. Conventional liquid level measurement intelligent sensing devices are unable to meet the accurate measurement requirements of supercritical operating conditions due to insufficient environmental adaptability and weak anti-interference capabilities. However, radio frequency admittance level gauges, as intelligent sensing devices adapted to extreme operating conditions, can accurately measure the water level of supercritical water storage tanks thanks to their extreme environment-resistant structural design and anti-interference working principle. Therefore, they are widely used in industrial Internet-related scenarios such as supercritical power plants and energy storage, effectively solving the adaptation pain points of conventional intelligent sensing devices.

[0004] However, existing radio frequency admittance level gauges (which belong to the category of intelligent sensing level devices) used in supercritical water tanks are prone to damage to their electrode surfaces due to scaling and corrosion, which can lead to sensor failure. In such cases, the water tank must be shut down and the intelligent sensing device removed for maintenance or replacement. This not only interrupts the continuous acquisition of level data in the industrial internet scenario but also causes production process interruption, seriously affecting production and maintenance efficiency. Summary of the Invention

[0054] 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.

[0055] Please see Figures 1-4 In one embodiment of the present invention, the provided supercritical water tank level measuring device includes a radio frequency admittance level gauge body 1.

[0056] It also includes a cleaning mechanism 2, which is located on the outside of the radio frequency admittance level gauge body 1. The cleaning mechanism 2 includes a cleaning unit 21, which is located on the outside of the radio frequency admittance level gauge body 1. The cleaning unit 21 can clean the scale on the surface of the radio frequency admittance level gauge body 1.

[0057] Specifically, the cleaning unit 21 provided in this embodiment includes a cylindrical cylinder 2104, and a plurality of reset springs 2105 are provided inside the cylindrical cylinder 2104. The plurality of reset springs 2105 are arranged in a circumferential array around the cylindrical cylinder 2104.

[0058] Among them, the bottom end of the return spring 2105 is fixedly connected to the annular plate 2106, and the bottom surface of the annular plate 2106 is fixedly connected to the drive shaft 2108.

[0059] like Figure 4 As shown, a scraper 2107 is provided below the circular cylinder 2104 provided in this embodiment. A rectangular box 2109 is fixedly connected to the upper surface of the scraper 2107. A positioning block 2110 is slidably connected inside the rectangular box 2109. The upper part of the positioning block 2110 is fixedly connected to the bottom end of the transmission shaft 2108.

[0060] Furthermore, in this embodiment, the bottom end of the cylindrical tube 2104 is fixedly connected to a guide shaft 2101, and the scraper 2107 is slidably sleeved and connected to the guide shaft 2101. By providing a cleaning unit 21, the cleaning unit 21 can automatically clean the scale on the surface of the RF admittance level gauge body 1, preventing the problem of low production efficiency caused by the need to stop the equipment for disassembly and processing due to the accumulation of a large amount of scale on the surface of the RF admittance level gauge body 1.

[0061] Please see Figure 1 and Figure 2 A flange 2102 is fixedly connected to the outer surface of the RF admittance level gauge body 1. A sealing ring 2103 is fixedly connected to the bottom surface of the flange 2102. The top end of the cylindrical tube 2104 is fixedly connected to the bottom surface of the flange 2102. The top end of the return spring 2105 is fixedly connected to the bottom surface of the flange 2102.

[0062] In this embodiment, a flange 2102 and a sealing ring 2103 are provided. The flange 2102 allows the equipment to be installed on the water tank and put into operation, while the sealing ring 2103 seals the area between the flange 2102 and the water tank to prevent the medium inside the water tank from leaking out.

[0063] Please see Figure 4 In this embodiment, the upper surface of the positioning block 2110 is provided with a first bullseye bearing 2111. The outer surface of the first bullseye bearing 2111 is in contact with the inner top wall of the rectangular box 2109. By providing the first bullseye bearing 2111, the friction between the rectangular box 2109 and the positioning block 2110 can be reduced when the rectangular box 2109 slides.

[0064] When in use, the staff needs to use tools to insert the bolts 2217 into the pre-set fixing holes 2218 on the surface of the flange 2102 and the sealing ring 2103. By tightening the bolts 2217, the flange 2102 is securely installed on the top of the water tank. During this process, the sealing ring 2103 will be tightly squeezed by the flange 2102 and the top plane of the water tank to form a reliable sealing structure, which effectively prevents the leakage of the medium in the water tank.

[0065] When the water tank is replenished, the internal water level gradually rises, and the pressure inside the tank increases synchronously. This increased pressure acts on the upper surface of the annular plate 2106, generating a downward thrust that drives the annular plate 2106 downwards. Because the outer edge of the annular plate 2106 is tightly fitted to the inner wall of the cylindrical cylinder 2104, the annular plate 2106 maintains stable sliding inside the cylindrical cylinder 2104, preventing displacement. As the annular plate 2106 moves downwards, the two drive shafts 2108 fixedly connected to its bottom surface move downwards synchronously. The bottom ends of the drive shafts 2108 are connected to the positioning blocks... The positioning block 2110 is fixedly connected to the rectangular box 2109, and the positioning block 2110 is slidably connected inside the rectangular box 2109. Therefore, the drive shaft 2108 will drive the scraper 2107, which is fixed to the rectangular box 2109, to move downward. During the movement, the guide hole opened inside the scraper 2107 will slide along the outer surface of the guide shaft 2101. The top end of the guide shaft 2101 is fixedly connected to the bottom end of the cylindrical cylinder 2104, which can provide precise guidance for the scraper 2107, guiding the scraper 2107 to gradually approach the surface of the RF admittance level gauge body 1. At this time, the scraper 2107 will slide to... The position where the scraper 2107 contacts the surface of the RF admittance level gauge body 1 is such that the rectangular box 2109, the positioning block 2110, and the first bullseye bearing 2111 fixed on the upper surface of the positioning block 2110 cooperate with each other. The first bullseye bearing 2111 can reduce the friction between the positioning block 2110 and the inner top wall of the rectangular box 2109, ensuring that the scraper 2107 will not detach from the drive shaft 2108 during the closing process, and can still stably receive the thrust transmitted by the drive shaft 2108. As the pressure inside the water tank continues to increase, the pressure of the scraper 2107 on the surface of the RF admittance level gauge body 1 gradually increases. The scale adhering to the surface is thoroughly scraped off. After the water inside the tank is discharged through the drainage system, the pressure inside the tank will gradually decrease. At this time, the annular plate 2106 will move upward under the elastic tension of the return spring 2105. The top end of the return spring 2105 is fixedly connected to the bottom surface of the flange 2102, and the bottom end is fixedly connected to the upper surface of the annular plate 2106. Its elasticity can drive the annular plate 2106, the drive shaft 2108 and the scraper 2107 to return to the initial position, thus completing a complete scraping cycle and preparing for the next scraping work.

[0066] Please see Figures 5-8In this embodiment of the invention, the supercritical water tank level measuring device of this embodiment further includes a collection unit 22, which is disposed on the outside of the radio frequency admittance level gauge body 1.

[0067] The collection unit 22 is capable of collecting the scale that has been cleaned off;

[0068] Specifically, in this embodiment, the collecting unit 22 includes a fixing block 2204, the upper surface of which is fixedly connected to the bottom end of the cylindrical cylinder 2104, the inner wall of which is rotatably connected to a spiral cylinder 2209, the inner wall of which is threadedly connected to a threaded ring 2212, the bottom end of which is fixedly connected to a rotating shaft 2210, the outer surface of which is slidably connected to the inside of the fixing block 2204, and the outer surface of which is fixedly connected to a rotating plate 2202.

[0069] A rotating plate 2202 is disposed below a fixed block 2204. A storage box 2208 is disposed inside the rotating plate 2202. A limiting block 2214 is fixedly connected to the outer surface of the rotating shaft 2210. A limiting groove 2215 is formed on the outer surface of the fixed block 2204. The outer surface of the limiting block 2214 is slidably connected to the inside of the limiting groove 2215. A baffle 2216 is fixedly connected to the bottom surface of the fixed block 2204.

[0070] This embodiment includes a collection unit 22, which can collect and process the scale scraped off the surface of the radio frequency admittance level gauge body 1, and discharge the collected scale while the equipment is running normally.

[0071] Please see Figure 5 The inner wall of the flange 2102 and the inner wall of the sealing ring 2103 are fixedly connected to the long cylinder 2201. The bottom end of the long cylinder 2201 is covered with a layer of rubber. The bottom surface of the long cylinder 2201 is in contact with the upper surface of the rotating plate 2202. By providing the long cylinder 2201, the presence of the long cylinder 2201 can provide a discharge space for scale.

[0072] Please see Figure 3 and Figure 5 The inner wall of the long cylinder 2201 is threaded with a threaded cap 2203. The interior of the long cylinder 2201 and the interior of the rotating plate 2202 are both provided with a vent hole 2211. By providing the threaded cap 2203, the long cylinder 2201 can be sealed to prevent the pressure inside the water tank from being released to the outside through the long cylinder 2201. High-pressure gas can be delivered to the interior of the rotating plate 2202 through the vent hole 2211 to push the scale upward.

[0073] Please see Figure 2The upper surface of the flange 2102 and the upper surface of the sealing ring 2103 are provided with several identical fixing holes 2218. Each fixing hole 2218 is equipped with a bolt 2217. By providing fixing holes 2218, the equipment can be installed in a suitable position using fixing holes 2218 and bolts 2217.

[0074] Please see Figure 3 and Figure 5 The spiral cylinder 2209 is slidably connected to the spiral shaft 2205 inside. The surface of the spiral shaft 2205 is slidably connected to the inside of the circular cylinder 2104. The top end of the spiral shaft 2205 is fixedly connected to the bottom surface of the annular plate 2106. By providing the spiral shaft 2205, the power generated when the annular plate 2106 descends can be transmitted to the spiral cylinder 2209, and the spiral cylinder 2209 can be driven to rotate.

[0075] When the equipment performs scraping operations, as the annular plate 2106 moves downward, the spiral shaft 2205, which is fixedly connected to the center of its bottom surface, is simultaneously pushed downward. The outer surface of the spiral shaft 2205 is machined with continuous spiral stripes, while the inner wall of the spiral cylinder 2209 has spiral grooves that match the spiral stripes. As the spiral shaft 2205 moves downward, it gradually enters the interior of the spiral cylinder 2209. The spiral stripes on the surface of the spiral shaft 2205 embed into the spiral grooves on the inner wall of the spiral cylinder 2209. Under the action of the spiral structure, the linear motion of the spiral shaft 2205 is converted into a spiral motion. The rotation of the cylinder 2209 causes the spiral cylinder 2209 to rotate around its own axis. The inner wall of the spiral cylinder 2209 is machined with internal threads, which cooperate with the external threads of the threaded ring 2212. Theoretically, when the spiral cylinder 2209 rotates, it will drive the threaded ring 2212 and the rotating shaft 2210 fixedly connected to it to rotate synchronously. However, a limiting block 2214 is fixedly connected to the outer surface of the rotating shaft 2210, and a limiting groove 2215 extending axially is opened on the outer surface of the fixed block 2204. The outer surface of the limiting block 2214 is slidably connected to the inside of the limiting groove 2215, and the limiting groove 2215 limits the limiting block. The rotational freedom of 2214 is restricted, so under the combined action of the limiting block 2214 and the limiting groove 2215, the rotating shaft 2210 cannot rotate with the screw cylinder 2209. At this time, the rotational motion of the screw cylinder 2209 is converted into the linear motion of the rotating shaft 2210 along the axial direction under the action of the threaded connection, which drives the rotating shaft 2210 to move downward, and in turn drives the rotating plate 2202 fixedly connected to the surface of the rotating shaft 2210 and the storage box 2208 set inside the rotating plate 2202 to move downward synchronously. As the rotating shaft 2210 continues to move downward, the limiting block 2214 will move along the limiting groove 2215. As the slot 2215 gradually slides to the slot opening position, when the rotating plate 2202 and the storage box 2208 move directly below the RF admittance level gauge body 1, the limiting block 2214 completely disengages from the limiting effect of the limiting slot 2215. At this time, the spiral cylinder 2209 continues to rotate, which will drive the threaded ring 2212 and the rotating shaft 2210 to rotate together. The rotating shaft 2210 drives the limiting block 2214 to rotate 180 degrees clockwise, so that the rotating plate 2202 and the storage box 2208 are precisely rotated to directly below the RF admittance level gauge body 1, ensuring that the scraped scale can fall smoothly into the storage box 2208.

[0076] Meanwhile, the spiral stripes on the surface of the spiral shaft 2205 have completely detached from the spiral grooves on the inner wall of the spiral cylinder 2209. The subsequent descent of the annular plate 2106 will no longer cause the rotating shaft 2210, rotating plate 2202, and storage box 2208 to rotate or move. At this point, the storage box 2208 can stably collect the scraped scale. After the scale collection is completed, as the water tank pressure decreases, the annular plate 2106 drives the spiral shaft 2205 to return to its original position, and the spiral cylinder 2209 rotates in the opposite direction. Under the action of the threads, it drives the rotating shaft 2210, rotating plate 2202, and storage box 2208 to move upward and return to their original position. During the return process, the limiting block 2214 re-enters the limiting groove 2215, restricting the rotation of the rotating plate 2202. Finally, the upper surface of the rotating plate 2202 is in close contact with the bottom end of the long cylinder 2201. The bottom end of the long cylinder 2201 is covered with a layer of elastic rubber material. It has excellent sealing performance, capable of filling the tiny gap between the rotating plate 2202 and the long cylinder 2201, greatly preventing gas from entering the long cylinder 2201 from the water tank, ensuring the overall sealing of the equipment. When the staff needs to clean the scale collected inside the storage box 2208, first use a tool to apply rotational force to the threaded cap 2203 connected to the inner wall of the long cylinder 2201, removing the threaded cap 2203 from the inside of the long cylinder 2201. Then, connect the air pipe of the external air pump to the top opening of the long cylinder 2201, start the air pump to deliver compressed gas into the vent 2211. The compressed gas acts on the upper surface of the storage box 2208 through the vent 2211, generating an upward thrust, causing the storage box 2208 to move upward under the air pressure and pop out from inside the rotating plate 2202. Then the staff can easily clean the scale inside the storage box 2208.

[0077] Please see Figure 9 and Figure 10 In one implementation of the present invention, the supercritical water tank level measuring device provided in this embodiment further includes a detection mechanism 3, which is disposed on the outside of the radio frequency admittance level gauge body 1.

[0078] Specifically, the detection mechanism 3 in this embodiment can perform self-inspection on the sealing condition of the sealing structure;

[0079] Specifically, the detection mechanism 3 of this embodiment includes a servo motor 301. The output end of the servo motor 301 is fixedly connected to a rotating shaft 306. The outer surface of the rotating shaft 306 is rotatably connected to the inner wall of the flange 2102. A guide plate 304 is fixedly connected to the outer surface of the rotating shaft 306. A circular hole 302 is opened on the upper surface of the flange 2102. A lifting shaft 305 is slidably connected inside the circular hole 302. A second bullseye bearing 307 is fixedly connected to the outer surface of the lifting shaft 305. The top end of the lifting shaft 305 contacts the bottom surface of the guide plate 304. A fixing plate 303 is fixedly connected to the upper surface of the flange 2102. The outer surface of the fixing plate 303 is fixedly connected to the outer surface of the servo motor 301. A control box 2207 is fixedly connected to the upper surface of the flange 2102. A controller 2213 is fixedly connected to the inner bottom wall of the control box 2207. A movable cover 2206 is movably hinged to the upper surface of the control box 2207. The controller 2213 is electrically connected to the servo motor 301 through a wire.

[0080] This invention embodiment, by setting up a detection mechanism 3, can check the state of the sealing ring 2103 between the radio frequency admittance level gauge body 1 and the water tank. By setting up a cleaning unit 21, a collection unit 22 and a detection mechanism 3, the problem of needing staff to periodically shut down the equipment to check the radio frequency admittance level gauge body 1 during use can be effectively avoided.

[0081] When the elastic performance of the sealing ring 2103 needs to be tested, the operator can send a command through the control terminal to start the servo motor 301 in the testing mechanism 3. The output end of the servo motor 301 is fixedly connected to the rotating shaft 306 through a coupling. When the servo motor 301 runs, it drives the rotating shaft 306 to rotate around its own axis. A guide plate 304 is fixedly connected to the outer surface of the rotating shaft 306. The guide plate 304 rotates synchronously with the rotating shaft 306. In the initial state, the lower surface of the guide plate 304 contacts the top end of the lifting shaft 305 and applies downward pressure to the lifting shaft 305, causing the bottom end of the lifting shaft 305 to squeeze the sealing ring 2103. When the guide plate 304 rotates with the rotating shaft 306 to a specific angle, The lower surface of the guide plate 304 no longer contacts the top of the lifting shaft 305, and the pressure on the lifting shaft 305 disappears. At this time, the originally squeezed sealing ring 2103 will tend to recover its deformation due to its own elasticity, and apply an upward reaction force to the bottom of the lifting shaft 305, pushing the lifting shaft 305 to move upward. The better the elasticity of the sealing ring 2103, the stronger its ability to recover its deformation, the greater the upward thrust generated on the lifting shaft 305, and the higher the distance the lifting shaft 305 moves upward. The upper surface of the flange 2102 is provided with a circular hole 302, and the lifting shaft 305 is slidably connected inside the circular hole 302. The circular hole 302 provides guidance for the lifting shaft 305, ensuring that it can only move along the axial direction and avoiding lateral deviation.

[0082] After the servo motor 301 drives the rotating shaft 306 and guide plate 304 to rotate one revolution, the guide plate 304 will rotate again to a position opposite to the lifting shaft 305. The surface of the guide plate 304 is designed with a slope, which can convert the rotational motion of the guide plate 304 into an axial thrust on the lifting shaft 305. As the guide plate 304 continues to rotate, the slope will contact the second bullseye bearing 307 fixed at the top of the lifting shaft 305. The second bullseye bearing 307 can convert sliding friction into rolling friction, significantly reducing the frictional resistance between the guide plate 304 and the lifting shaft 305, so that the guide plate 304 can push the lifting shaft 305 to move downward again more smoothly until the bottom of the lifting shaft 305 applies stable pressure to the sealing ring 2103 again, completing one elastic detection cycle. The servo motor 301 is usually equipped with a high-precision encoder, which can collect the position signal of the motor rotor in real time. The signal is fed back to the servo driver to obtain real-time information such as the motor's position and speed. Simultaneously, the servo driver can monitor the motor's current in real time. By analyzing current changes and combining them with position and speed data from the encoder, it can indirectly sense the resistance encountered by the motor during rotation. When the motor pushes the lifting shaft 305 downwards, if the resistance increases, the motor needs to output greater torque to maintain normal speed, resulting in a corresponding increase in the motor's operating current. Conversely, when the resistance decreases, the current decreases. The driver can determine the resistance encountered by the lifting shaft 305 based on the current change pattern, thereby indirectly determining the elasticity of the sealing ring 2103. Greater resistance indicates a stronger reaction force of the sealing ring 2103 on the lifting shaft 305, meaning better elasticity of the sealing ring 2103; conversely, less resistance indicates poorer elasticity of the sealing ring 2103.

[0083] In this embodiment of the invention, the servo motor 301 establishes an electrical connection with the controller 2213 inside the control box 2207 via a wire. This allows the servo motor 301 to transmit data signals such as current, speed, and position during operation to the controller 2213 in real time. The controller 2213 integrates a wireless transmission module, which can transmit the processed elasticity detection data of the sealing ring 2103 to the mobile terminal of external personnel in the form of a wireless signal. This enables personnel to obtain the sealing status and elasticity performance information of the sealing ring 2103 in a timely manner, so as to decide whether the sealing ring 2103 needs to be maintained or replaced based on the detection results.
