Description

Technical Field

[0001] The present invention relates to the technical field of optocoupler flowmeters, and in particular to a three-way pipe quick-connect optocoupler flowmeter. Background Art

[0002] In modern industrial production and scientific research, accurate measurement of fluid flow is crucial. Optocoupler flowmeters have emerged. As precision instruments that work based on the principle of optical coupling, their core components include a light source, a light detector, and a measuring tube. When the fluid flows through the measuring tube, characteristics such as the intensity, frequency, or phase of the light change accordingly. The light detector sensitively captures these changes and converts them into electrical signals. Subsequently, through professional analysis and processing, the fluid flow information can be accurately obtained. With outstanding advantages such as high precision, strong reliability, fast response speed, and strong anti-interference ability, optocoupler flowmeters are widely used in many fields such as petroleum, chemical industry, water treatment, and pharmaceuticals, and have become key equipment for ensuring the stability of the production process and monitoring fluid flow.

[0003] Chinese Patent with the publication number "CN117191134A" discloses an easily assembled optocoupler flowmeter. This device has certain innovation in design. Through a base, a housing, an impeller, and a supporting installation structure, a relatively convenient assembly process is achieved. For example, the cooperation between the rotating shafts on both sides of the impeller and the upper and lower arc grooves on the mounting seat ensures the normal rotation of the impeller.

[0004] However, in actual application scenarios, this device exposes obvious limitations. In terms of connection with a three-way pipe, its inlet pipe and outlet pipe mostly adopt threaded connection or flange connection methods. In the case of threaded connection, once rust, dust, sand blockage, etc. occur, the thread is extremely likely to slip, resulting in difficult disassembly and assembly. In an environment prone to vibration, long-term vibration will cause the threaded connection to become loose, seriously affecting the normal operation and measurement accuracy of the flowmeter. Although flange connection is relatively stable, it also requires the assistance of bolts for installation, with cumbersome operation and many hidden dangers in harsh environments. In summary, the defects in the connection method of existing optocoupler flowmeters greatly limit their stable operation and efficient application in complex working conditions, and there is an urgent need to innovate and improve the design of key parts such as their connection structure to meet diverse usage requirements.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] First, in the present invention, through the coordinated cooperation of the linkage mechanism, the adjustment mechanism and the transmission gear set, the installation convenience of the present optical coupler flowmeter and the three-way pipe joint is effectively improved. During installation, the three-way pipe joint can be inserted into both ends of the flowmeter. By twisting the adjustment shaft, it drives the rail frame, the rotating shaft and a series of gear transmissions, driving the sliding ring to rotate, so that the arc-shaped clamping frame can be accurately inserted into the arc-shaped clamping sleeve to complete a firm connection. After installation, the limiting spring pushes the limiting pin into the limiting hole to lock the coupling shaft and fix each component to ensure a firm connection, significantly improving the actual use convenience;

[0019] Second, during the application of this device, by setting the adjustment mechanism, the convenience of disassembly, assembly, inspection and repair can be further improved. During use, the adjustment shaft can be pushed to move the movable block inward, compress the limit spring, drive the limit pin to disengage from the limit hole, release the shaft connection limit, and then adjust the shaft connection. Through gear transmission, the slip ring rotates reversely, and the arc-shaped clamping frame disengages from the arc-shaped socket, and then the three-way pipe joint can be easily pulled out, and the optoelectronic flowmeter body can be quickly removed, greatly improving the equipment maintenance efficiency and realizing the quick connection and disconnection of the two;

[0020] Third, the support and fixation component ensures the stable operation of the optoelectronic flowmeter. First, it is installed on the equipment or wall through the installation holes and bolts of the installation plate. When installing the support and fixation component, the adjustment sleeve and the support rod are slid to adjust the length to adapt to different scenarios. After adjustment, it is fixed with bolts, and then the installation screw rod is twisted and inserted into the card hole to lock the support rod and the sleeve. Through the adjusted and fixed support rod and sleeve, strong support is provided for the flowmeter, enhancing the operation stability. Brief Description of the Drawings

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figures 1-9 , in the embodiment of the present invention, a three-way pipe quick-connect optocoupler flowmeter includes an optocoupler flowmeter body 1. An adjusting mechanism 6 is fixedly installed on one side of the optocoupler flowmeter body 1. Connector 4 is fixedly installed on both sides of the optocoupler flowmeter body 1. A linkage mechanism 3 is arranged outside the connector 4. The linkage mechanism 3 and the adjusting mechanism 6 are linked. A clamping mechanism 7 is arranged outside the linkage mechanism 3. A three-way pipe joint 5 is installed outside the connector 4 through the clamping mechanism 7. A support and fixation assembly 2 is arranged outside the connector 4;

[0033] The adjustment mechanism 6 includes a guide rail 61 which is fixedly connected to the front of the opto-coupled flowmeter body 1. Inside the guide rail 61, there is a transmission gear set 62. On the front of the guide rail 61, an adjustment set 63 is fixedly installed. The rear side of the adjustment set 63 is fixedly connected to the front of the transmission gear set 62. The outer side of the transmission gear set 62 is in transmission connection with the linkage mechanism 3. During use, when it is necessary to connect the three-way pipe joint 5, operate the adjustment set 63. The action of the adjustment set 63 will drive the transmission gear set 62 fixedly connected to it to operate inside the guide rail 61. Since the outer side of the transmission gear set 62 is in transmission connection with the linkage mechanism 3, when the transmission gear set 62 rotates, it will transmit power to the linkage mechanism 3. After the linkage mechanism 3 is driven, it will drive the outer clamping mechanism 7 to work. The clamping mechanism 7 realizes the clamping with the three-way pipe joint 5 through specific actions, so as to install the three-way pipe joint 5 outside the connector 4. The support and fixation assembly 2 plays a role in supporting and strengthening the connector 4 and the overall structure, ensuring the stable operation of the equipment. The guide rail 61 in the adjustment mechanism 6 provides an operating track for the transmission gear set 62. Each component cooperates with each other to realize the quick connection and stable support of the three-way pipe joint 5 and the opto-coupled flowmeter body 1. Through the mutual cooperation and linkage of the above structures, the clamping mechanisms 7 on both sides can be quickly docked, facilitating the quick docking of the three-way pipe joint 5 and the opto-coupled flowmeter body 1.

[0034] Please refer to Figures 1-8 , the linkage mechanism 3 includes an annular rail 31 and a fixing plate 32. The annular rail 31 is fixedly installed at one end of the outer surface of the connector 4 away from the opto-coupled flowmeter. Inside the annular rail 31, a sliding ring 33 is slidably connected. On the outer side of the sliding ring 33, a bevel gear ring 34 is fixedly installed. The fixing plate 32 is fixedly installed at both ends of the guide rail 61. On the side of the fixing plate 32 close to the opto-coupled flowmeter, a bevel gear 35 is rotatably connected. The bevel gear 35 is meshed with the bevel gear ring 34. The clamping mechanism 7 is fixedly connected to the side of the bevel gear ring 34 away from the opto-coupled flowmeter. The bevel gear 35 is in transmission connection with the transmission gear set 62. When the adjustment set 63 in the adjustment mechanism 6 drives the transmission gear set 62 to rotate, since the bevel gear 35 is in transmission connection with the transmission gear set 62, the transmission gear set 62 will drive the bevel gear 35 to rotate. And because the bevel gear 35 is meshed with the bevel gear ring 34 fixed on the outer side of the sliding ring 33, when the bevel gear 35 rotates, it will drive the bevel gear ring 34 meshed with it to rotate. And the sliding ring 33 is slidably connected inside the annular rail 31 fixed on the outer surface of the connector 4. Therefore, when the bevel gear ring 34 rotates, it will drive the sliding ring 33 to slide inside the annular rail 31. Since the clamping mechanism 7 is fixedly connected to the side of the bevel gear ring 34 away from the opto-coupled flowmeter, the rotation of the bevel gear ring 34 will drive the clamping mechanism 7 to move, so that the clamping mechanism 7 can perform clamping or separating operations on the three-way pipe joint 5, realizing the quick connection and disassembly of the three-way pipe joint 5 and the connector 4.

[0035] Please refer toFigures 5-8 , the clamping mechanism 7 includes a fixed block 71 and a fixed column 72. The fixed blocks 71 are arranged in an equidistant circular pattern and fixedly connected to the outside of the bevel gear 35. The fixed columns 72 are arranged in an equidistant circular pattern and fixedly connected to the inner end of the outer surface of the three-way pipe joint 5. An arc-shaped clamping frame 73 is fixedly connected to the outside of each fixed block 71. An arc-shaped clamping sleeve 74 is fixedly connected to the outside of each fixed column 72. The end of the arc-shaped clamping frame 73 is inserted into the inside of the arc-shaped clamping sleeve 74. The arc-shaped clamping sleeve 74 and the arc-shaped clamping frame 73 are both concentric with the slip ring 33. The inner end of the three-way pipe joint 5 is inserted into the inside of the connector 4, and an anti-slip rubber ring is fixedly connected to the outer surface of the three-way pipe joint 5. When the slip ring 33 in the linkage mechanism 3 rotates under the drive of the bevel gear ring 34 in the circular rail 31, the connected fixed block 71 also rotates synchronously. Since the fixed blocks 71 are arranged in an equidistant circular pattern outside the bevel gear ring 34 and each has an arc-shaped clamping frame 73 fixedly connected to its outside, the arc-shaped clamping frame 73 will make a circular motion around the slip ring 33 as the fixed block 71 rotates. At the same time, the fixed columns 72 fixedly connected to the inner end of the outer surface of the three-way pipe joint 5 in an equidistant circular pattern will also be relatively stationary with the installation position of the three-way pipe joint 5. The arc-shaped clamping sleeve 74 fixedly connected to the outside of the fixed column 72 corresponds to the position of the arc-shaped clamping frame 73. When the arc-shaped clamping frame 73 rotates with the slip ring 33 to a specific position, its end will accurately be inserted into the inside of the arc-shaped clamping sleeve 74. Since the arc-shaped clamping sleeve 74 and the arc-shaped clamping frame 73 are both concentric with the slip ring 33, it ensures the accuracy and stability of the insertion action, thereby realizing their tight clamping and firmly installing the three-way pipe joint 5 at the connector 4. The anti-slip rubber ring fixedly connected to the outer surface of the three-way pipe joint 5 will closely fit with the inner wall of the connector 4 during installation, increasing the friction and further preventing the three-way pipe joint 5 from loosening, ensuring the stability of the connection.

[0036] Please refer to Figures 1-9, the transmission gear set 62 includes a slide plate 621, a first gear 622 and a second gear 623. The slide plate 621 is slidably connected to the inner top and bottom of the guide rail 61. Rack bars 624 are fixedly connected to the inner sides of the slide plate 621. The first gear 622 is rotatably connected to the middle inside the guide rail 61. The first gear 622 is meshed and connected with the rack bars 624. The second gear 623 is fixedly installed on the front of the bevel gear 35. The outer side of the first gear 622 penetrates through the guide rail 61 and is meshed and connected with the second gear 623. The adjustment set 63 includes a fixed ring 631 and a connecting shaft 632. The connecting shaft 632 is fixedly installed on the front of the first gear 622. The fixed ring 631 is fixedly installed in the middle of the front of the guide rail 61. A limiting component 633 is fixedly installed at one end of the connecting shaft 632 away from the first gear 622. The outer side of the limiting component 633 is clamped with the fixed ring 631. The limiting component 633 includes a limiting hole 6331 and a rail frame 6332. The rail frame 6332 is fixedly installed at the front end of the connecting shaft 632. The limiting holes 6331 are arranged in an equidistant annular pattern on the inner side inside the fixed ring 631. Limiting springs 6333 are fixedly connected to both ends of the rail frame 6332. The outer ends of the limiting springs 6333 are fixedly connected with movable blocks 6334. The movable blocks 6334 are slidably connected to both ends inside the rail frame 6332. A limiting pin 6335 is fixedly installed on the outer side of the movable block 6334. The end of the limiting pin 6335 penetrates through the rail frame 6332 and is inserted into the inside of the limiting hole 6331. During use, when it is necessary to adjust the clamping state of the clamping mechanism 7 on the three-way pipe joint 5, the adjustment set 63 can be operated. The rail frame 6332 in the adjustment set 63 drives the connecting shaft 632 to rotate under an external force. The connecting shaft 632 is fixedly connected with the first gear 622, so that the first gear 622 rotates. Since the first gear 622 is meshed with the rack bars 624 on the inner side of the slide plate 621, when the first gear 622 rotates, it will drive the rack bars 624 to drive the slide plate 621 to slide on the inner top and bottom of the guide rail 61. At the same time, the outer side of the first gear 622 penetrates through the guide rail 61 and is meshed with the second gear 623. The rotation of the first gear 622 will drive the second gear 623 to rotate. And the second gear 623 is fixedly installed on the front of the bevel gear 35. Therefore, when the second gear 623 rotates, the bevel gear 35 rotates accordingly. The bevel gear 35 is meshed with the bevel gear ring 34 in the linkage mechanism 3, thereby driving the bevel gear ring 34 and the clamping mechanism 7 connected thereto to act. After the adjustment is completed, the limiting component 633 plays a role. The limiting springs 6333 at both ends of the rail frame 6332 push the movable blocks 6334 to slide outward inside the rail frame 6332, so that the end of the limiting pin 6335 on the outer side of the movable block 6334 penetrates through the rail frame 6332 and is accurately inserted into the limiting holes 6331 arranged in an equidistant annular pattern on the inner side of the fixed ring 631. Through the clamping of the limiting pin 6335 and the limiting hole 6331, the positions of the rail frame 6332, the connecting shaft 632 and the first gear 622 are fixed.Ensure the stable state of the transmission gear set 62 and the subsequent linkage and clamping mechanisms 7, and maintain the established connection state between the three-way pipe joint 5 and the connector 4.

[0037] Please refer to Figure 9 On the front surface of the movable block 6334, an adjusting shaft 6336 is fixedly installed. A non-slip grip sleeve is fixedly connected to the outer surface of the adjusting shaft 6336. During the operation of the three-way pipe quick-connect optoelectronic flowmeter, the adjusting shaft 6336 and the non-slip grip sleeve play a key auxiliary role. When adjustment of the device is required, for example, to change the operating state of the transmission gear set 62, thereby affecting the linkage mechanism 3 and the clamping mechanism 7, the operator can apply force by holding the adjusting shaft 6336. The adjusting shaft 6336 is fixedly installed on the front surface of the movable block 6334. When the operator rotates the adjusting shaft 6336, the movable block 6334 will move accordingly. Since the movable block 6334 is closely connected to the limiting component 633, its movement will drive the limiting spring 6333 to compress or extend, causing the limiting pin 6335 to be withdrawn from or inserted into the limiting hole 6331, thereby unlocking or locking the positions of components such as the rail frame 6332, the coupling shaft 632, and the first gear 622. The non-slip grip sleeve is fixedly connected to the outer surface of the adjusting shaft 6336, increasing the friction between the operator's hand and the adjusting shaft 6336, enabling the operator to apply force to rotate the adjusting shaft 6336 more stably, comfortably, and precisely, avoiding operation errors caused by hand slippage, effectively improving the convenience and reliability of the adjustment operation, and ensuring that the entire device can smoothly achieve functions such as connecting or separating the three-way pipe joint 5 and the connector 4.

[0038] Please refer to Figures 1-6, the support and fixation assembly 2 includes a mounting ring 21 which is movably mounted on the outer surface of the connector 4. A support rod 22 is fixedly installed at the bottom of the mounting ring 21. A sleeve 23 is sleeved and slid on the outer surface of the support rod 22. A mounting plate 24 is fixedly installed at the bottom of the sleeve 23. An installation screw 25 is threadedly connected to the inner side of the upper end of the sleeve 23. The end of the installation screw 25 penetrates through the sleeve 23. The installation screw 25 is set as a hand-tightening screw. A plurality of clamping holes 26 are arranged at equal intervals and linearly on the inner side of the support rod 22. The end of the installation screw 25 is inserted into the inner side of the clamping hole 26. Mounting holes 27 are formed at both ends of the mounting plate 24. The mounting holes 27 are set as countersunk holes. During installation, the mounting ring 21 is movably sleeved on the outer surface of the connector 4. According to the actual installation scenario requirements, the sliding position of the support rod 22 in the sleeve 23 is adjusted to change the overall length of the combination of the support rod 22 and the sleeve 23. After the length adjustment is completed, by rotating the hand-tightening installation screw 25, since the inner side of the upper end of the sleeve 23 is threadedly connected, the installation screw 25 will gradually screw in. After its end penetrates through the sleeve 23, it is accurately inserted into the clamping holes 26 arranged at equal intervals and linearly on the inner side of the support rod 22, so as to fix the relative position of the support rod 22 and the sleeve 23. Then, by using the countersunk holes formed at both ends of the mounting plate 24 and cooperating with bolts and other connecting parts, the mounting plate 24 can be stably mounted on the surface of the equipment, the wall and other supporting structures. In this way, the support and fixation assembly 2 provides stable support for the connector 4 and the entire opto-coupler flowmeter, enhances the stability of the device during operation, ensures the reliable operation of the opto-coupler flowmeter, and at the same time, the countersunk hole design can make the surface flat after the bolt is installed, avoiding potential safety hazards caused by the protrusion of the bolt or affecting the installation of other components.

[0039] The working principle of the present invention is as follows: By setting up a linkage component, an adjustment component 63, and a transmission gear group 62 to cooperate with each other, the installation convenience of the optocoupler flowmeter body 1 and the three-way pipe joint 5 can be effectively improved. During the installation process, after accurately inserting the three-way pipe joint 5 into both ends of the optocoupler flowmeter body 1, the operator only needs to twist the adjustment shaft 6336 to drive the rail frame 6332 to displace, thereby driving the rotation of the rotating shaft. The rotation of the rotating shaft causes the first gear 622 to rotate accordingly. The rotation of the first gear 622 drives the rack 624 inside the guide rail 61, driving the slide plate 621 to slide along a specific direction. The sliding of the rack 624 further drives the second gear 623 to rotate. The rotation of the second gear 623 causes the bevel gear 35 engaged with it to start operating. The bevel gear 35 drives the bevel gear ring 34 to rotate, and the bevel gear ring 34 drives the slip ring 33 to perform a circular motion. During this process, the rotation of the slip ring 33 drives each arc-shaped clamping frame 73 to rotate and displace synchronously until the arc-shaped clamping frame 73 accurately inserts into the arc-shaped clamping sleeve 74. Through the tight insertion and limitation of the two, the stable connection between the three-way pipe joint 5 and the optocoupler flowmeter body 1 is realized. After the installation is completed, the limiting spring 6333 automatically takes effect, pushing the movable block 6334 to move outward. The movable block 6334 drives the limiting pin 6335 to insert into the limiting hole 6331. Through the accurate insertion and limitation of the limiting pin 6335 and the limiting hole 6331, the coupling shaft 632 is firmly clamped, thereby fixing the linkage component, the transmission gear group 62, and the clamping mechanism 7 as a whole, ensuring the stable connection between the connecting head 4 and the three-way pipe structure, and significantly improving the convenience of the device in actual use;

[0040] When the device needs to be disassembled, assembled, and overhauled, the operation is also simple and efficient. The operator only needs to push the adjustment shaft 6336 to drive the movable block 6334 to move inward. The movement of the movable block 6334 compresses the limiting spring 6333, making it in a compressed state. At the same time, the movable block 6334 drives the limiting pin 6335 to move inward synchronously until the limiting pin 6335 completely withdraws from the limiting hole 6331, releasing the limitation on the coupling shaft 632. At this time, the operator can flexibly adjust and push the coupling shaft 632 to drive the rail frame 6332 to rotate. The rotation of the rail frame 6332 drives the coupling shaft 632 and the first gear 622 to rotate in sequence. Through the precise transmission between the first gear 622, the rack 624, the second gear 623, the bevel gear 35, and the bevel gear ring 34, the slip ring 33 is driven to rotate reversely. The reverse rotation of the slip ring 33 drives the arc-shaped clamping frame 73 to disengage from the arc-shaped clamping sleeve 74. After the arc-shaped clamping frame 73 is separated from the arc-shaped clamping sleeve 74, the three-way pipe joint 5 can be easily pulled out from the inside of the connecting head 4, realizing the rapid removal of the optocoupler flowmeter body 1. This innovative design enables the device to quickly complete the disassembly, assembly, and overhaul work of the optocoupler flowmeter body 1 during use, greatly improving the equipment maintenance efficiency and ensuring that the optocoupler flowmeter body 1 and the three-way pipe body can be quickly connected and disconnected;

[0041] The supporting and fixing component 2 provided by the present invention provides a solid guarantee for the stable operation of the opto-coupler flowmeter body 1. During use, firstly, the mounting holes 27 on the mounting plate 24 can be used to stably mount the mounting plate 24 on the outer surface of the device or the wall by means of bolts. When installing the supporting and fixing component 2, by adjusting the relative sliding of the sleeve 23 and the support rod 22, the total length of the support rod 22 and the sleeve 23 can be flexibly adjusted to meet the requirements for the supporting length in different installation scenarios. After adjusting the length, the supporting and fixing component 2 is installed and fixed again by means of bolts using the mounting plate 24 and the mounting holes 27. Finally, the mounting screw 25 is twisted to insert it into the clamping hole 26 to complete the clamping and fixing of the support rod 22 and the sleeve 23. The support rod 22 and the sleeve 23 after length adjustment and fixation can provide a strong supporting and strengthening effect for the opto-coupler flowmeter body 1, significantly enhancing the stability of the opto-coupler flowmeter body 1 during operation.
