Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic flowmeters, in particular to a pipeline ultrasonic flowmeter that can be quickly installed. Background Art

[0002] A pipeline ultrasonic flowmeter is an instrument that uses ultrasonic technology to measure the flow velocity of fluids, such as liquids or gases, flowing in a closed pipeline. It determines the flow velocity by measuring the time difference of ultrasonic signals propagating in the fluid, and then calculates the flow rate. This type of flowmeter has the characteristics of non-invasive, no pressure loss, simple installation, and low maintenance cost, and is widely used in industries such as water treatment, chemical industry, petroleum, food, and beverage.

[0003] A pipeline ultrasonic flowmeter that can be quickly installed is an instrument for measuring fluid flow rate. It detects the flow velocity of the fluid flowing through the pipeline through ultrasonic technology. The characteristics of this type of flowmeter are simple and fast installation, without the need to interrupt the fluid flow in the pipeline, nor the need to cut or weld the pipeline, thus reducing the installation time and cost.

[0004] There is a Chinese patent with the reference publication number CN217236888U. It discloses a pipeline ultrasonic flowmeter, which includes a pipeline. Connecting blocks are installed on the left and right sides of the top of the pipeline. Through grooves are opened on the left and right sides of the connecting blocks. Sleeves are sleeved on the outer walls of the connecting blocks. An ultrasonic flowmeter is bolted to the inner sides of the left and right sleeves. A measuring instrument is installed at the bottom end of the acoustic flowmeter. A base is clamped in the inner cavity of the sleeve. A stopper is in contact with the bottom end of the base. A groove is opened in the stopper along the left-right direction. A slider is embedded in the inner cavity of the groove. For this pipeline ultrasonic flowmeter, the convenient installation and disassembly functions of the acoustic flowmeter are realized through structures such as the pipeline, connecting blocks, through grooves, acoustic flowmeter, measuring instrument, sleeves, base, stopper, groove, slider, cross bar, spring, clamping block, and cylindrical groove. The beneficial effects are obvious and the applicability is strong.

[0005] Although this patent is convenient for installation and disassembly, the limiting effect is achieved through the clamping connection between the groove and the spring. This structure has certain drawbacks. When a part of the spring is bent under the influence of force, it may cause the force evenly exerted by the spring to be inconsistent, thereby directly affecting the tightness of the clamping connection. In addition, when installing the spring, a corresponding damping structure needs to be prepared separately to facilitate the spring to rebound. The structure of this patent is complex, increasing the expenditure of manufacturing costs, and its structure also needs to be processed and improved, increasing the processes and reducing the work efficiency. Therefore, the inventor has proposed a pipeline ultrasonic flowmeter that can be quickly installed to solve the above-mentioned technical problems. Summary of the Utility Model

[0006] The utility model aims to overcome the above deficiencies and provide a technical solution that can solve the above problems.

[0007] A pipe-type ultrasonic flowmeter that can be quickly installed, comprising a pipe body, a protective housing, and a flowmeter installed inside the protective housing. The flowmeter is an ultrasonic flowmeter. The structure between the pipe body and the protective housing is detachable. One end of the protective housing is a connecting rod, and the top of the connecting rod is a connection head with an external thread. The surface of the pipe body is provided with a threaded groove with an internal thread for mating installation with the connection head; Threaded connection can provide good mechanical engagement, ensuring that the connecting rod and the pipe body will not loosen easily, thereby improving the stability of the overall structure. At the same time, it is convenient for installation and disassembly. By screwing the thread in and out, the connecting rod can be easily installed or disassembled, facilitating maintenance and replacement of components. Moreover, the thread fit can form a good sealing interface, reducing the risk of liquid or gas leakage and improving the safety of the overall structure;

[0008] The inside of the protective housing is provided with an inner cavity for accommodating the flowmeter. The inner surface of the inner cavity is connected with a limiting block. The middle of the limiting block is provided with a limiting card slot for limiting the position of the flowmeter. The surface of the flowmeter can slide along the surface of the limiting card slot; This structure can ensure the correct installation position of the flowmeter inside the protective housing and allows the flowmeter to be fine-tuned during installation or maintenance to achieve the best measurement effect. At the same time, the limiting card slot can prevent the flowmeter from moving excessively, thus avoiding damage caused by vibration or external force, ensuring the stability and measurement accuracy of the flowmeter. The limiting block can also absorb and disperse the impact force on the flowmeter to a certain extent, further protecting the flowmeter from damage;

[0009] When installing the flowmeter, just make the two ends of the flowmeter slide along the surface of the limiting card slot. This structure provides a way for quick disassembly and assembly, improving the installation efficiency and also the disassembly efficiency.

[0010] Furthermore, both the connecting rod and the inner cavity are hollow. The surface of the flowmeter is connected with an installation wire, and the surface of the installation wire is connected with a fixing head. The inside of the connecting rod is a wire placement groove for accommodating the installation wire and the fixing head. The surface of the wire placement groove is provided with a magnetic attraction groove for mating installation with the fixing head, and the magnetic attraction groove penetrates the surface at both ends of the connecting rod;

[0011] The hollow design of the connecting rod and the inner cavity allows the installation wires and the fixed head of the flowmeter to be arranged through the wire slot, while the magnetic adsorption slots on the surface of the wire slot provide a paired installation structure for the fixed head, enabling the fixed head to be firmly adsorbed on the connecting rod through the magnetic adsorption slots, thus ensuring the stability of the installation wires and the reliability of the connection. This design simplifies the installation process, improves the firmness of the connection, and facilitates the maintenance and replacement of the flowmeter. The use of magnetic adsorption slots enables the fixed head to be quickly adsorbed or released, thereby quickly installing or disassembling the fixed head at one end of the flowmeter.

[0012] Furthermore, the middle part of the pipe body is a flow channel, and a connection component for paired use with the flowmeter is provided on the surface of the pipe body. The connection component includes a connecting pipe and a wiring. A pipe orifice is opened inside the connecting pipe, and one end of the pipe orifice extends beyond the surface of the flow channel. One end of the wiring abuts against the surface of the connecting pipe, and the other end of the wiring abuts against the fixed head inside the magnetic adsorption slot. The wiring, the connecting pipe, and the fixed head are all detachable structures.

[0013] Since the wiring and the connecting pipe are detachable, when maintenance or replacement is required, they can be easily separated, thereby reducing maintenance time and costs. The use of detachable structures allows operators to adjust or upgrade according to different needs, improving the flexibility and adaptability of the equipment. When parts need to be disassembled or replaced, the detachable structures can reduce potential damage to other parts, and each part can be replaced separately, while also reducing the cost of maintenance.

[0014] When installing the flowmeter, the installation wires and the fixed head at one end of the flowmeter fall into the inside of the wire slot. Through the magnetic adsorption force of the magnetic adsorption slot, the fixed head is smoothly connected to the magnetic adsorption slot, and then the wiring is connected to the fixed head through manual operation, so that the wiring is smoothly connected to the installation wires, completing the preliminary preparation for measurement.

[0015] Furthermore, the connecting pipe is limited to the surface of the pipe body by a limit bolt. The connecting pipe is inclined and installed at both ends of the pipe body, and the flow channel runs through the middle part of the pipe body. The ultrasonic flowmeter is based on the fact that when ultrasonic waves propagate in a fluid, their propagation speed is affected by the flow velocity of the fluid. The ultrasonic flowmeter internally contains two ultrasonic transducers, which serve as a transmitter and a receiver respectively, and the two transducers work alternately to transmit and receive ultrasonic signals.

[0016] When the ultrasonic signal is transmitted from the upstream transducer to the downstream transducer, due to the flow of the fluid inside the flow channel, the propagation time of the signal will be shorter than that in a static fluid. On the contrary, when the signal is transmitted from the downstream transducer to the upstream transducer, the propagation time will be longer. By measuring the propagation time difference of the ultrasonic waves in these two directions, the flow velocity of the fluid can be calculated, and then, combined with the cross-sectional area of the pipe, the flow rate of the fluid can be obtained.

[0017] The inclined installation of the connecting pipe helps to reduce the resistance of the fluid in the pipe, thereby improving the fluid transmission efficiency. In addition, the connecting pipe is connected to the pipe at a 45° angle. When one end helps to reduce the resistance of the fluid in the pipe, the other connecting pipe bears the resistance of the fluid in the pipe directly, so that two different sets of detection data can be obtained to ensure that the resistance value remains within a reasonable range. At the same time, the inclined installation of the connecting pipe makes the maintenance and replacement work more convenient. The inclined angle can provide a better operating space and vision, facilitating the operator to stand and conform to the setting of the force application point, and making the force application point of the operator uniform.

[0018] Furthermore, baffles are provided at both ends of the pipe body. The diameter of the baffle is larger than that of the pipe body. A number of threaded holes for connecting external screws are provided on the surface of the baffle. The threaded holes are arranged in a circular pattern on the surface of the baffle, and the distance between adjacent threaded holes is equally spaced. The threaded holes penetrate through the surfaces at both ends of the baffle.

[0019] The circular arrangement of the threaded holes ensures uniform distribution when connecting external screws. This structure helps to disperse the pressure, improve the stability and load-bearing capacity of the pipe body connection. The equally spaced threaded holes ensure symmetry and aesthetics during installation, and are also convenient for installation and maintenance. The threaded holes penetrate through the surfaces at both ends of the baffle, allowing the operator to connect from either side of the pipe body, which provides convenience for installation and disassembly and makes the connection of the pipe body more flexible and convenient.

[0020] Furthermore, a cap is connected to the top of the protective housing. The protective housing and the cap are detachable structures. A stepped card slot for mating installation with the cap is provided on the surface of the protective housing.

[0021] The detachable structure provides a convenient way to maintain and replace the cap. The setting of the stepped card slot enables the cap to be firmly fitted with the protective housing, and can be easily disassembled and replaced when needed to adapt to different usage environments or replace damaged components. In addition, this structure helps to improve the overall durability and adaptability of the product, allowing users to choose caps of different materials or designs according to needs to achieve better protection effects. The cap also plays a role in protecting the inner cavity and the flowmeter, reducing the probability of external objects or liquids falling into the inner cavity and damaging the surface of the flowmeter.

[0022] Furthermore, one end of the flowmeter is a display screen. Both ends of the flowmeter are card boards that are paired with the limit card slots. A number of anti-slip lines for increasing friction are provided at one end of the card board, and the distance between adjacent anti-slip lines is equally spaced.

[0023] The display screen connected to one end of the flowmeter can assist the operator in real-time monitoring to display the flow data in real-time, facilitating the operator to promptly understand the flow situation, which is convenient for later analysis and data management. In addition, the operating status of the flowmeter can be visually and quickly identified through the display screen, helping to promptly detect and handle faults. Reading data directly from the display screen reduces the error of manual reading and improves the accuracy of the data;

[0024] By means of the anti-slip lines, when the clamping plate is inserted into or pulled out of the limit card slot, the anti-slip lines can evenly contact the limit card slot, thereby providing consistent friction. Adopting this design helps to improve the stability and reliability of the operation, reducing the phenomenon of the clamping plate tilting or jamming caused by uneven friction, ensuring a smooth and precise installation and disassembly process of the flowmeter. The equidistant setting provides consistent friction and reduces the increase or decrease of local acting forces, so as to reduce the operation flexibility during sliding.

[0025] Compared with the prior art, the beneficial effects of the present utility model are as follows: It is only necessary to make both ends of the flowmeter slide along the surface of the limit card slot. This structure provides a way for quick disassembly and assembly, improving the installation efficiency and also the disassembly efficiency. When it is necessary to replace flowmeters of different models, the flowmeter can be made to fall off the original installation position by pulling it out, and the new flowmeter can be installed by sliding it along the surface of the limit card slot. Through this structure, the process of quick disassembly and assembly can be completed, achieving the effect of flexible replacement;

[0026] In addition, the threaded connection can provide good mechanical engagement, ensuring that the connecting rod and the pipe body will not easily loosen, thereby improving the stability of the overall structure. At the same time, it is convenient for installation and disassembly. By screwing the thread in and out, the connecting rod can be easily installed or disassembled, which is convenient for maintenance and replacement of components. Moreover, the threaded fit can form a good sealing interface, reducing the risk of liquid or gas leakage and improving the safety of the overall structure. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation mode

[0036] The following further describes the present utility model in detail in conjunction with the accompanying drawings and specific implementation modes.

[0037] In this embodiment, please refer to Figures 1 - 8 , a specifically implemented quickly installable pipeline ultrasonic flowmeter includes a pipe body 1, a protective housing 2, and a flowmeter 3 installed inside the protective housing 2. The flowmeter 3 is an ultrasonic flowmeter. The pipe body 1 and the protective housing 2 are of a detachable structure. One end of the protective housing 2 is a connecting rod 4, and the top of the connecting rod 4 is a connecting head 5 with an external thread. The surface of the pipe body 1 is provided with a thread groove 6 with an internal thread for mating installation with the connecting head 5; Threaded connection can provide good mechanical engagement, ensuring that the connecting rod 4 and the pipe body 1 will not loosen easily, thereby improving the stability of the overall structure. At the same time, it is convenient for installation and disassembly. By screwing in and out the thread, the connecting rod 4 can be easily installed or disassembled, facilitating maintenance and component replacement. Moreover, the thread fit can form a good sealing interface, reducing the risk of liquid or gas leakage and improving the safety of the overall structure;

[0038] The interior of the protective housing 2 is provided with an inner cavity 7 for accommodating the flowmeter 3. The inner surface of the inner cavity 7 is connected with a limiting block 8. The middle of the limiting block 8 is provided with a limiting card slot 9 for limiting the position of the flowmeter 3. The surface of the flowmeter 3 can slide along the surface of the limiting card slot 9. This structure can ensure the correct installation position of the flowmeter 3 inside the protective housing 2 and allows the flowmeter 3 to be finely adjusted during installation or maintenance to achieve the best measurement effect. At the same time, the limiting card slot 9 can prevent the flowmeter 3 from moving excessively, thus avoiding damage caused by vibration or external force, ensuring the stability and measurement accuracy of the flowmeter 3. The limiting block 8 can also absorb and disperse the impact force on the flowmeter 3 to a certain extent, further protecting the flowmeter 3 from damage;

[0039] When installing the flowmeter 3, just slide both ends of the flowmeter 3 along the surface of the limiting card slot 9. This structure provides a way for quick disassembly and assembly, improving the installation efficiency and also the disassembly efficiency.

[0040] Both the connecting rod 4 and the inner cavity 7 are hollow. The surface of the flowmeter 3 is connected with an installation wire 10. The surface of the installation wire 10 is connected with a fixing head 11. The interior of the connecting rod 4 is a wire placement groove 12 for accommodating the installation wire 10 and the fixing head 11. The surface of the wire placement groove 12 is provided with a magnetic attraction groove 13 for mating installation with the fixing head 11. The magnetic attraction groove 13 penetrates through the surfaces at both ends of the connecting rod 4;

[0041] The hollow design of the connecting rod 4 and the inner cavity 7 allows the installation wire 10 and the fixing head 11 of the flowmeter 3 to be arranged through the wire placement groove 12. The magnetic attraction groove 13 on the surface of the wire placement groove 12 provides a mating installation structure for the fixing head 11, enabling the fixing head 11 to be firmly adsorbed on the connecting rod 4 through the magnetic attraction groove 13, thus ensuring the stability of the installation wire 10 and the reliability of the connection. Using this design simplifies the installation process, improves the firmness of the connection, and is convenient for maintaining and replacing the flowmeter 3. The use of the magnetic attraction groove 13 allows the fixing head 11 to be quickly adsorbed or released, thus quickly installing or disassembling the fixing head 11 at one end of the flowmeter 3.

[0042] The middle of the pipe body 1 is a flow channel 14. The surface of the pipe body 1 is provided with a connection component for mating with the flowmeter 3. The connection component includes a connection pipe 15 and a wiring 16. The inside of the connection pipe 15 is provided with a pipe orifice 17. One end of the pipe orifice 17 extends beyond the surface of the flow channel 14. One end of the wiring 16 abuts against the surface of the connection pipe 15, and the other end of the wiring 16 abuts against the fixing head 11 inside the magnetic attraction groove 13. The wiring 16, the connection pipe 15 and the fixing head 11 are all detachable structures;

[0043] Since the wiring 16 and the connecting pipe 15 are detachable, they can be easily separated when maintenance or replacement is required, thereby reducing maintenance time and costs. The use of a detachable structure allows operators to adjust or upgrade according to different needs, improving the flexibility and adaptability of the equipment. When parts need to be disassembled or replaced, the detachable structure can reduce potential damage to other parts. Each part can be replaced separately, while also reducing the cost of maintenance.

[0044] When installing the flowmeter 3, the installation wire 10 and the fixed head 11 at one end of the flowmeter 3 fall into the interior of the wire placement groove 12. Through the magnetic adsorption force of the magnetic adsorption groove 13, the fixed head 11 is smoothly connected to the magnetic adsorption groove 13. Then, through manual operation, the wiring 16 is connected to the fixed head 11, so that the wiring 16 is smoothly connected to the installation wire 10, completing the preliminary preparation for measurement.

[0045] The connecting pipe 15 is limited to the surface of the pipe body 1 by the limit bolt 18. The connecting pipe 15 is inclined and installed at both ends of the pipe body 1, and the flow channel 14 penetrates through the middle of the pipe body 1. The ultrasonic flowmeter is based on the fact that when ultrasonic waves propagate in a fluid, their propagation speed will be affected by the flow velocity of the fluid. The ultrasonic flowmeter internally contains two ultrasonic transducers (not shown), which serve as a transmitter and a receiver respectively. The two transducers work alternately to transmit and receive ultrasonic signals.

[0046] When the ultrasonic signal is transmitted from the upstream transducer to the downstream transducer, due to the flow of the fluid inside the flow channel 114, the propagation time of the signal will be shorter than that in a stationary fluid. On the contrary, when the signal is transmitted from the downstream transducer to the upstream transducer, the propagation time will be longer. By measuring the propagation time difference of the ultrasonic waves in these two directions, the flow velocity of the fluid can be calculated. Furthermore, by combining the cross-sectional area of the pipe, the flow rate of the fluid can be obtained.

[0047] The inclined installation of the connecting pipe 15 helps to reduce the resistance of the fluid in the pipe 1, thereby improving the fluid transmission efficiency. In addition, the connecting pipe 15 is connected to the pipe 1 at a 45° angle. When one end helps to reduce the resistance of the fluid in the pipe 1, the other connecting pipe 15 directly bears the resistance of the fluid in the pipe 1, so that two different sets of detection data can be obtained to ensure that the resistance value remains within a reasonable range. At the same time, the inclined installation of the connecting pipe 15 makes maintenance and replacement work more convenient. The inclined angle can provide better operating space and vision, facilitating the operator to stand and conform to the setting of the force application point, and making the force application points of the operator uniform.

[0048] Both ends of the tube body 1 are provided with baffles 19. The diameter of the baffle 19 is larger than that of the tube body 1. A plurality of threaded holes 20 for connecting external screws are formed on the surface of the baffle 19. The threaded holes 20 are arranged annularly on the surface of the baffle 19. The distance between adjacent threaded holes 20 is equally spaced. The threaded holes 20 penetrate through the surfaces at both ends of the baffle 19.

[0049] The annular arrangement of the threaded holes 20 ensures uniform distribution when connecting external screws. This structure helps to disperse pressure, improve the stability and load-bearing capacity of the connection of the tube body 1. The equally spaced threaded holes 20 ensure symmetry and aesthetics during installation, and are also convenient for installation and maintenance. The threaded holes 20 penetrate through the surfaces at both ends of the baffle 19, allowing operators to connect from either side of the tube body 1, which provides convenience for installation and disassembly, and makes the connection of the tube body 1 more flexible and convenient.

[0050] A cap 21 is connected to the top of the protective housing 2. The protective housing 2 and the cap 21 are of a detachable structure. A stepped card slot 22 for mating installation with the cap 21 is provided on the surface of the protective housing 2.

[0051] The detachable structure provides a convenient way for maintenance and replacement of the cap 21. The setting of the stepped card slot 22 enables the cap 21 to be stably matched with the protective housing 2, and at the same time can be easily disassembled and replaced when needed to adapt to different usage environments or replace damaged parts. In addition, this structure helps to improve the overall durability and adaptability of the product, allowing users to select caps 21 of different materials or designs according to needs to achieve better protection effects. The cap 21 also plays a role in protecting the inner cavity 7 and the flowmeter 3, reducing the probability of external objects or liquids falling into the inner cavity 7 and thus damaging the surface of the flowmeter 3.

[0052] One end of the flowmeter 3 is a display screen 23. Both ends of the flowmeter 3 are card boards 24 for mating with the limit card slots 9. A plurality of anti-slip lines 25 for increasing friction are provided at one end of the card board 24. The distance between adjacent anti-slip lines 25 is equally spaced.

[0053] The display screen 23 connected to one end of the flowmeter 3 can assist the operator in real-time monitoring to display the flow data in real time, facilitating the operator to timely understand the flow situation and being convenient for later analysis and data management. In addition, the operating state of the flowmeter 3 can be directly and quickly identified through the display screen 23, which helps to timely detect and handle faults. Reading data directly from the display screen 23 reduces the error of manual reading and improves the accuracy of the data.

[0054] By means of the anti-slip lines 25, when the card board 24 is inserted into or pulled out of the limit card slot 9, the anti-slip lines 25 can be in uniform contact with the limit card slot 9, thereby providing consistent frictional force. Adopting this design helps to improve the stability and reliability of the operation, reduce the tilting or jamming phenomenon of the card board 24 caused by uneven frictional force, and ensure the smooth and precise installation and disassembly process of the flowmeter 3. The equidistant setting provides consistent frictional force and reduces the increase or decrease of local acting forces, so as to reduce the operation flexibility during sliding.

[0055] The operation process of the utility model is as follows: When installing the flowmeter 3, the two ends of the flowmeter 3 can be slid along the surface of the limit card slot 9. This structure provides a way for quick disassembly and assembly, improving the installation efficiency and also the disassembly efficiency.

[0056] At the same time, the installation wire 10 and the fixed head 11 at one end of the flowmeter 3 fall into the inside of the wire placement groove 12. Through the magnetic adsorption force of the magnetic adsorption groove 13, the fixed head 11 is smoothly connected to the magnetic adsorption groove 13. Then, through manual operation, the wiring 16 is connected to the fixed head 11, so that the wiring 16 is smoothly connected to the installation wire 10, completing the preliminary preparation for measurement.

[0057] When measuring, since the wiring 16 is smoothly connected to the installation wire 10, and the connecting pipe 15 is connected to the pipe 1 at a 45° angle. When one end helps to reduce the resistance of the fluid in the pipe 1, the front of the other connecting pipe 15 bears the resistance of the fluid in the pipe 1. Thus, two groups of different detection data can be obtained to ensure that the resistance value is kept within a reasonable range. Through the display screen 23, it can assist the operator to conduct real-time monitoring to display the flow data in real time, facilitating the operator to timely understand the flow situation for later analysis and data management. In addition, through the display screen 23, the operation state of the flowmeter 3 can be intuitively and quickly identified, which helps to timely discover and handle faults. Reading data directly from the display screen 23 reduces the error of manual reading and improves the accuracy of the data.

[0058] The design key point of the utility model lies in that the two ends of the flowmeter 3 are slid along the surface of the limit card slot 9. This structure provides a way for quick disassembly and assembly, improving the installation efficiency and also the disassembly efficiency. When it is necessary to replace flowmeters of different models, the flowmeter 3 can be taken out of the original installation position by pulling out, and the new flowmeter 3 can be slid along the surface of the limit card slot 9 to complete the installation. Through this structure, the process of quick disassembly and assembly can be completed, achieving the effect of flexible replacement.

[0059] In addition, a good mechanical bite can be provided through threaded connection, ensuring that the connecting rod 4 and the pipe body 1 will not loosen easily, thereby improving the stability of the overall structure. At the same time, it is convenient for installation and disassembly. By screwing the thread in and out, the connecting rod 4 can be easily installed or disassembled, which is convenient for maintenance and replacement of components. Moreover, the threaded fit can form a good sealing interface, reducing the risk of liquid or gas leakage and improving the safety of the overall structure.

[0060] The above content is a further detailed description of the present utility model in combination with specific preferred embodiments. It cannot be determined that the specific implementation of the present utility model is only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model belongs, without departing from the concept of the present utility model, several simple deductions or replacements can still be made, which should all be regarded as the protection scope of the present utility model.
