Description

Technical Field

[0001] This utility model relates to the field of ultrasonic flow meter technology, and in particular to an online plug-in ultrasonic flow meter. Background Technology

[0002] Ultrasonic flow meters are widely used for fluid velocity measurement. In continuous production scenarios, the measuring pipeline is often filled with fluid medium. If a malfunction occurs during non-normal maintenance, the disassembly and assembly of the ultrasonic flow meter can significantly impact continuous production efficiency. Most existing ultrasonic flow meters that can be disassembled and maintained without interrupting the fluid medium in the pipeline rely on removing fasteners and then manually inserting and removing the flow meter. Due to the weight of the equipment, this is not only inconvenient to operate and difficult for a single person to complete independently, but also carries risks such as impact injuries.

[0003] Manual insertion and removal is not only inefficient, but may also lead to poor sealing and leakage. In some complex industrial environments, such as high temperature, high pressure, and strong corrosion, the difficulty and danger of manual operation are further increased. Traditional disassembly and insertion methods are difficult to meet the needs of actual production. Frequent manual disassembly and assembly may also cause certain wear and damage to the equipment, shorten the service life of the equipment, and increase the maintenance and replacement costs of the equipment. Utility Model Content

[0004] To address the problems of existing online plug-in ultrasonic flow meters relying on manual operation, which is inconvenient and inefficient, this invention provides an online plug-in ultrasonic flow meter that can achieve the plugging and unplugging of the flow meter through a lifting assembly without interrupting the fluid medium in the pipeline. This not only simplifies operation but also saves time and effort.

[0005] This invention provides an online pluggable ultrasonic flow meter for detecting fluid flow in a pipeline. The flow meter includes a transmitter, a conduit, a sensor, and a lifting assembly. The transmitter is mounted on one end of the conduit, and the sensor is mounted on the other end. The sensor is connected to the transmitter via a wire passing through the conduit. The lifting assembly is positioned between the transmitter and the pipeline. The sensor is inserted into or removed from the pipeline via the lifting assembly. The lifting assembly pushes the transmitter, the connected conduit, and the sensor downwards, allowing the sensor to accurately reach the detection position within the pipeline. When the sensor needs inspection or maintenance, the lifting assembly reverses direction, lifting the sensor smoothly out of the pipeline.

[0006] Furthermore, the pipeline is radially equipped with a nozzle for sensor insertion. The nozzle is fitted with a switching valve, which has an upper flange and a lower flange. The switching valve connects to the nozzle via the lower flange. A lifting assembly is positioned between the transmitter and the upper flange. When sensor insertion is required, the switching valve is opened, allowing the sensor to pass smoothly through the valve and into the nozzle, ultimately reaching the detection position within the pipeline. When sensor inspection or maintenance is needed, the lifting assembly raises the sensor, smoothly pulling it out of the pipeline, and then the switching valve is closed.

[0007] Furthermore, a transition pipe is installed between the transmitter and the upper flange, and a transition cavity is provided inside the transition pipe. The guide tube passes through the transition cavity and is fitted with the transition cavity with a clearance. This not only ensures the stability of the guide tube within the transition cavity, preventing the guide tube from shaking or shifting during equipment operation and thus affecting the normal operation of the sensor, but also provides a certain degree of protection for the guide tube, avoiding damage to the guide tube from external factors.

[0008] Furthermore, a limiting step is formed between the bottom of the transition cavity and the conduit, and a limiting ring adapted to the limiting step is provided at the end of the conduit. During the sensor removal process, when the limiting ring abuts against the limiting step, the switching valve is closed, thereby enabling online insertion and removal installation.

[0009] Furthermore, the lifting assembly includes a lead screw and a connecting rod. One end of the connecting rod is fixed to the transmitter via a base one, and the other end is fixed to a transition tube via a base two. The connecting rod is connected to the lead screw via a connecting block and can move along the lead screw. The connecting rod is rotatably connected to base one, base two, and the connecting block. The rotation of the lead screw can drive the connecting block to move linearly along the lead screw. Because the connecting rod is rotatably connected to the connecting block, the connecting rod can rotate accordingly as the connecting block moves, thereby realizing the lifting and lowering of the transmitter.

[0010] Furthermore, an adjusting block is provided at one end of the lead screw, and a stop block is provided at the other end. A rotating lever is inserted into the adjusting block. The adjusting block can be driven by rotating the rotating lever, which in turn drives the lead screw to rotate. The stop block is provided to prevent the connecting block from slipping off the end of the lead screw during movement, ensuring the safety and stability of the entire lifting assembly.

[0011] Furthermore, the end of the rotating lever is equipped with a handle for easy gripping, and the surface of the handle has anti-slip textures to facilitate the application of force. The anti-slip textures can effectively increase the friction between the hand and the handle, reduce the possibility of hand slippage during force application, and improve the safety and convenience of operation.

[0012] Furthermore, the sensor head adopts a streamlined shape to reduce the impact on fluid flow within the pipe. This greatly minimizes the interference of the sensor head on the fluid within the pipe, allowing the fluid to flow smoothly within the pipe.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention provides an online plug-in ultrasonic flow meter. A lifting assembly drives the sensor for plugging and unplugging, eliminating the need for direct manual intervention and avoiding the inconvenience and risks of manual operation. Simultaneously, the precise control of the lifting assembly ensures the accuracy of the sensor's plugging and unplugging position, guaranteeing a sealing effect and reducing the possibility of leakage. Furthermore, compared to manual operation, the lifting assembly's movement is more stable and standardized, effectively reducing wear and tear on the equipment, extending its service life, and significantly lowering maintenance and replacement costs.

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0021] To enable automatic insertion and removal of the flow meter without interrupting the flow medium in the pipeline, an online insertion and removal ultrasonic flow meter is designed, such as... Figure 1 and 2As shown, the flow meter used to detect the fluid flow rate in the pipe 8 includes a transmitter 1, a conduit 2, a sensor 3, and a lifting assembly 7. The transmitter 1 is installed at one end of the conduit 2, and the sensor 3 is installed at the other end. The sensor 3 is connected to the transmitter 1 through a wire passing through the conduit 2. The lifting assembly 7 is installed between the transmitter 1 and the pipe 8. The sensor 3 is inserted into or pulled out of the pipe 8 through the lifting assembly 7.

[0022] During installation, adjusting the lifting assembly 7 lowers the transmitter 1, allowing the sensor 3 to pass through the guide tube 2 from the transition chamber and inside the switching valve 5 and be inserted into the pipe 8 for measurement. For maintenance, adjusting the lifting assembly 7 raises the transmitter 1. When the sensor 3 enters the transition chamber and the limiting ring 21 at the end of the guide tube 2 abuts against the limiting step 61, it is fully raised. The switching valve 5 is then closed, enabling online insertion and removal. The lifting assembly 7 uses a linkage mechanism; the lifting is adjusted by rotating the lead screw 71 to complete the insertion and removal action.

[0023] Pipeline 8 is radially equipped with a nozzle 4 for insertion of sensor 3. A switching valve 5 is mounted on nozzle 4, and the switching valve 5 has an upper flange 51 and a lower flange 52. The switching valve 5 is connected to nozzle 4 via the lower flange 52. A lifting assembly 7 is positioned between transmitter 1 and upper flange 51. The switching valve 5 effectively controls the flow of fluid within pipeline 8, ensuring operational safety. Simultaneously, the connection method of upper flange 51 and lower flange 52 ensures the stability of the connection between switching valve 5 and nozzle 4, preventing fluid leakage.

[0024] The lifting assembly 7 includes a lead screw 71 and a connecting rod 72. One end of the connecting rod 72 is fixed to the transmitter 1 via a base 1 73, and the other end is fixed to the transition tube 6 via a base 2 74. The connecting rod 72 is connected to the lead screw 71 via a connecting block 75 and can move along the lead screw 71. The connecting rod 72 is rotatably connected to the base 1 73, the base 2 74, and the connecting block 75.

[0025] In actual operation, when it is necessary to adjust the height of transmitter 1, rotate lead screw 71. Since connecting rod 72 is threadedly connected to lead screw 71 through connecting block 75, the rotation of lead screw 71 will drive connecting block 75 to make linear motion on lead screw 71. Since connecting rod 72 is rotatably connected to base 1 73, base 2 74 and connecting block 75, the linear motion of connecting block 75 will cause connecting rod 72 to rotate and swing, realizing the smooth lifting and lowering of transmitter 1, so as to meet the needs of sensor 3 being inserted into pipe 8 for measurement or pulled out of pipe 8 for maintenance.

[0026] One end of the lead screw 71 is equipped with an adjusting block 76, and the other end with a stop block 77. A rotating lever 78 is inserted into the adjusting block 76. By inserting the rotating lever 78 into the adjusting block 76, the operator can more easily apply rotational force, making the adjustment process more labor-saving. When it is necessary to rotate the lead screw 71, simply hold one end of the rotating lever 78 and rotate it with appropriate force to rotate the adjusting block 76, thereby causing the lead screw 71 to rotate. The stop block 77 serves as a limit, preventing the connecting block 75 from moving beyond the safe range on the lead screw 71. This avoids damage or detachment of components such as the connecting rod 72 due to excessive movement of the connecting block 75, ensuring the stable operation of the entire lifting assembly 7. In actual operation, the operator can flexibly use the rotating lever 78 to precisely control the lifting height of the transmitter 1 according to specific adjustment needs, adapting to different measurement and maintenance scenarios.

[0027] The end of the rotating lever 78 is equipped with a handle for easy gripping, and the surface of the handle has anti-slip textures to facilitate the application of force. The anti-slip textures effectively increase the friction between the hand and the handle, greatly reducing the risk of operational errors caused by hand slippage.

[0028] The head of sensor 3 features a streamlined design to minimize the impact on fluid flow within pipe 8. This allows fluid to pass more smoothly through the sensor head, significantly reducing fluid resistance and turbulence. When the fluid flows smoothly through the sensor, it effectively improves measurement accuracy and stability, reducing measurement errors caused by abnormal fluid flow. Simultaneously, it reduces the impact force of the fluid on the sensor head, extending the sensor's lifespan and minimizing damage and wear caused by prolonged fluid impact.

[0029] like Figure 3 As shown, a transition pipe 6 is also provided between the transmitter 1 and the upper flange 51. A transition cavity is provided inside the transition pipe 6, and the lead wire 2 passes through the transition cavity and is fitted with the transition cavity with a clearance. The transition pipe 6 is provided to guide the lead wire 2 and ensure its stable lifting and lowering, and to temporarily store and protect the pulled-out sensor 2. When the sensor 2 needs to be repaired, the lifting assembly 7 can be used to pull the sensor 2 out into the transition cavity of the transition pipe 6.

[0030] A limiting step 61 is formed between the bottom of the transition cavity and the guide tube 2, and a limiting ring 21 adapted to the limiting step 61 is provided at the end of the guide tube 2. When the sensor 2 needs to be inspected and pulled out into the transition cavity of the transition tube 6 using the lifting assembly 7, the limiting ring 21 abuts against the limiting step 61, which can prevent the guide tube 2 from rising excessively and detaching from the transition cavity, providing reliable protection for the temporary storage of the sensor 2. Moreover, this limiting structure design makes the installation and disassembly of the online plug-in ultrasonic flowmeter more convenient and safer, reducing the risk of equipment damage due to improper operation.

[0031] The above description is illustrative only and not restrictive of this utility model. Those skilled in the art will understand that many modifications, variations or equivalents can be made without departing from the spirit and scope defined by the appended claims, and all such modifications, variations or equivalents will fall within the protection scope of this utility model.
