Abstract
Description
Technical Field
[0001] This utility model relates to the field of ultrasonic flow meter technology, specifically to an ultrasonic flow meter that is easy to assemble and disassemble. Background Technology
[0002] An ultrasonic flow meter measures flow rate based on the principle that the propagation speed of ultrasonic waves in a fluid varies with the fluid velocity. It employs a non-invasive measurement method, does not disrupt the fluid flow state, has virtually zero pressure loss, high measurement accuracy, and a wide range. It offers advantages such as easy installation and low maintenance costs, and can be used for flow measurement of various media including water, gas, and oil. It is widely used in water supply and drainage, industrial production, and energy management.
[0003] According to a public disclosure (Publication No.: CN210321855U), an easy-to-install ultrasonic flow meter installation structure includes: an arc-shaped pressure plate; flat plates connected to opposite sides of the arc-shaped pressure plate; a probe slot on the surface of the arc-shaped pressure plate; limit plates symmetrically connected to both sides of the probe slot; pressure blocks slidably connected to the limit plates; rotating shafts rotatably connected to both ends of the flat plates; worm gears fixedly connected to the rotating shafts; a connecting rod connected to one end of the rotating shaft; a lower pressure plate rotatably connected to one end of the connecting rod, and a connecting shaft rotatably connected to one flat plate; and worms meshing with the worm gears connected to both ends of the connecting shaft. This utility model solves the problem of inconvenient probe installation and removal by fixing the probe by rotating the rotating shaft to press the lower pressure plate against the pipe, and then fixing the probe with pressure blocks. Furthermore, the distance between the lower pressure plate and the arc-shaped pressure plate can be adjusted according to the pipe diameter, effectively improving the adaptability to different pipe diameters and enhancing the overall installation and removal efficiency.
[0004] However, the above-mentioned applications have problems such as a large number of structural components, which increases manufacturing costs and the probability of failure. The process of disassembling and assembling each component during maintenance is cumbersome and time-consuming, and there is a lack of automated disassembly and assembly mechanisms. Utility Model Content
[0005] This invention proposes an ultrasonic flow meter that is easy to disassemble and assemble, solving the problems of related technologies, such as a large number of structural components, increased manufacturing costs and failure probability, cumbersome disassembly and assembly processes during maintenance, long time consumption, and lack of automated disassembly and assembly mechanisms.
[0006] According to one aspect, at least one embodiment of the present invention provides an ultrasonic flow meter that is easy to disassemble and assemble, comprising: a body, a base bolted to the circumferential surface of the body, a screw bolted to the top of the base, a detection tube fixedly connected to the circumferential surface of the body, a guide tube fixedly connected to the circumferential surface of the detection tube, a end of the guide tube away from the detection tube fixedly connected to the side of the base, a sealing cap snapped onto one end of the detection tube, a detection device bolted to the top of the base, a small screw bolted to the top of the detection device, a display screen electrically connected to the side of the detection device, a button electrically connected to the side of the detection device, and a disassembly and assembly clamping mechanism provided on the side of the body;
[0007] The disassembly and clamping mechanism includes a housing, which is fixedly connected to the side of the machine body. A motor is fixedly connected to the top of the housing, and a rotary button is electrically connected to the top of the motor. A threaded rod is fixedly connected to the output shaft of the motor. The end of the threaded rod away from the motor is rotatably connected to the inside of the housing. A threaded sleeve is threadedly connected to the circumferential surface of the threaded rod. A connecting block is fixedly connected to the circumferential surface of the threaded sleeve. An upper clamping plate is fixedly connected to the side of the connecting block. A sliding groove is opened inside the housing. The side of the upper clamping plate is slidably connected to the inside of the sliding groove. A threaded sleeve is threadedly connected to the circumferential surface of the threaded rod. A connecting block is fixedly connected to the circumferential surface of the threaded sleeve. A lower clamping plate is fixedly connected to the side of the connecting block. The side of the lower clamping plate is slidably connected to the inside of the sliding groove. A limit plate is provided inside the sliding groove. The side of the limit plate is fixedly connected to the inside of the sliding groove.
[0008] For example, in at least one embodiment of the present invention, an ultrasonic flow meter that is easy to disassemble and assemble is provided, which further includes: two screws are provided, and they are symmetrical to each other along the vertical central axis of the base. The two screws symmetrical to each other along the vertical central axis of the base can provide uniform fastening force, avoiding tilting or loosening of the base caused by single-point force. Two guide tubes, detection tubes and sealing caps are provided, and they are symmetrical to each other along the vertical central axis of the body. The symmetrical design of the double guide tubes and detection tubes makes the fluid flow uniformly in the equipment, reduces local pressure concentration, and reduces the impact of flow field disturbance on measurement accuracy.
[0009] The number of small screws is set to several and arranged in a circumferential array on the top of the detection device. The multiple small screws in the circumferential array can form a uniform pressure distribution on the top of the detection device, ensuring that the device is tightly connected and avoiding deformation or loosening caused by uneven force at a single point.
[0010] The width of the upper clamping plate is equal to the width of the lower clamping plate, and the radius of the holes in the upper and lower clamping plates is equal to the radius of the holes in the machine body. Workers can align the upper and lower clamping plates without additional calibration, simplifying the assembly process and reducing human error.
[0011] The limiting plate is located on the displacement trajectory of the upper clamping plate and the lower clamping plate. The bottom of the upper clamping plate is located above the top of the limiting plate, and the top of the lower clamping plate is located at the bottom of the limiting plate. The limiting plate, through physical blocking, ensures that the upper clamping plate and the lower clamping plate will not be excessively squeezed when closed, thus avoiding equipment deformation or sealing failure due to excessive pressure.
[0012] According to another aspect, at least one embodiment of the present invention also provides a convenient ultrasonic flow meter for disassembly and assembly, including: a detection sealing mechanism, the detection sealing mechanism including a detection guide hole, the detection guide hole being opened on the circumferential surface of the housing hole, a slide rail being provided at the end of the detection guide hole away from the housing, a slider being slidably connected inside the slide rail, a baffle being fixedly connected to the side of the slider, a second slide groove being provided inside the housing, and a sealing plate being slidably connected inside the second slide groove.
[0013] For example, in at least one embodiment of the present invention, an ultrasonic flow meter that is easy to disassemble and assemble is provided, which further includes: two sliders and two slide rails, which are symmetrical to each other along the vertical central axis of the detection guide hole; and two slide grooves, which are symmetrical to each other along the vertical central axis of the sealing plate, to ensure that the force on both sides of the sealing plate is evenly distributed and to avoid problems such as the sealing plate tilting due to uneven force.
[0014] The end of the detection guide hole away from the housing is located on the displacement trajectory of the slider, and the end of the detection guide hole away from the housing is located to the left of the slider, so that the fluid can flow into the detection guide hole in the sealed space.
[0015] The top of the baffle is located at the bottom of the sealing plate, and the width of the baffle is greater than the width of the sealing plate. The baffle is wider than the sealing plate so that the sealing plate can be completely blocked by the baffle during the falling process, so that the sealing plate can maintain the sealing function when the baffle does not move to the appropriate position.
[0016] The top of the sealing plate is located above the hole in the housing. The width of the sealing plate is greater than the diameter of the hole in the housing. The sealing plate is wider than the diameter of the hole in the housing, which can completely cover the hole in the housing without leaving any gaps, preventing fluid from leaking out from the edge of the hole and ensuring the tightness of the seal.
[0017] The working principle and beneficial effects of this utility model are as follows:
[0018] 1. This utility model utilizes the coordinated operation of components such as the threaded rod, threaded sleeve, and upper clamping plate in the clamping mechanism to quickly clamp and release the ultrasonic flowmeter body between the upper and lower clamping plates, significantly improving assembly and disassembly efficiency and reducing the difficulty of manual operation. Precise matching of clamping plate dimensions and precise control of the stroke by the limiting plate ensure uniform and stable clamping force, preventing equipment loosening or damage. Furthermore, this mechanism has a compact structure, strong safety protection performance, and can adapt to various equipment specifications. Its modular design facilitates troubleshooting and component replacement, effectively reducing maintenance costs and enhancing equipment reliability and practicality.
[0019] 2. This utility model ensures the sealing performance and accuracy of the ultrasonic flow meter through the cooperation of components such as the detection guide pipe, baffle, and sealing plate in the sealing mechanism, using multiple design features. The symmetrical distribution of double slide rails and double slide grooves ensures smooth movement of the baffle and sealing plate, enabling precise operation. The sealing plate covers the housing hole and its width is greater than the hole diameter, further enhancing the sealing effect, preventing fluid leakage, improving equipment reliability, and ensuring the accuracy and stability of measurement data.

[0031] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0032] like Figures 1-6As shown, this invention illustrates an easy-to-disassemble ultrasonic flow meter according to one embodiment of the present invention, comprising: a body 1, a base 2 bolted to the circumferential surface of the body 1, a screw 3 bolted to the top of the base 2, a detection tube 4 fixedly connected to the circumferential surface of the body 1, a guide tube 5 fixedly connected to the circumferential surface of the detection tube 4, one end of the guide tube 5 away from the detection tube 4 fixedly connected to the side of the base 2, a sealing cap 6 snapped onto one end of the detection tube 4, a detection device 7 bolted to the top of the base 2, a small screw 11 bolted to the top of the detection device 7, a display screen 8 electrically connected to the side of the detection device 7, a button 9 electrically connected to the side of the detection device 7, and a disassembly and clamping mechanism 10 provided on the side of the body 1.
[0033] The disassembly and clamping mechanism 10 includes a housing 101, which is fixedly connected to the side of the machine body 1. A motor 102 is fixedly connected to the top of the housing 101, and a rotary button 103 is electrically connected to the top of the motor 102. A threaded rod 104 is fixedly connected to the output shaft of the motor 102. One end of the threaded rod 104 away from the motor 102 is rotatably connected to the inside of the housing 101. A threaded sleeve 105 is threadedly connected to the circumferential surface of the threaded rod 104, and a connecting block 106 is fixedly connected to the circumferential surface of the threaded sleeve 105. An upper part is fixedly connected to the side of the connecting block 106. The upper clamping plate 107 and the box body 101 have a sliding groove 108 inside. The side of the upper clamping plate 107 is slidably connected to the inside of the sliding groove 108. The circumferential surface of the threaded rod 104 is threadedly connected to the threaded sleeve 109. The circumferential surface of the threaded sleeve 109 is fixedly connected to the connecting block 1010. The side of the connecting block 1010 is fixedly connected to the lower clamping plate 1011. The side of the lower clamping plate 1011 is slidably connected to the inside of the sliding groove 108. The inside of the sliding groove 108 is provided with a limiting plate 1012. The side of the limiting plate 1012 is fixedly connected to the inside of the sliding groove 108.
[0034] In some examples, the following are also included: two screws 3 are provided, and they are symmetrical to each other along the vertical central axis of the base 2. The two screws 3, which are symmetrical to each other along the vertical central axis of the base 2, can provide uniform fastening force and avoid tilting or loosening of the base 2 caused by single-point force. Two guide tubes 5, detection tubes 4 and sealing caps 6 are provided, and they are symmetrical to each other along the vertical central axis of the body 1. The symmetrical design of the double guide tubes 5 and detection tubes 4 makes the fluid flow uniformly in the equipment, reduces local pressure concentration, and reduces the impact of flow field disturbance on measurement accuracy.
[0035] The number of small screws 11 is set to several and arranged in a circumferential array on the top of the detection device 7. The multiple small screws 11 in the circumferential array can form a uniform pressure distribution on the top of the detection device 7, ensuring that the device is tightly connected and avoiding deformation or loosening caused by uneven force at a single point.
[0036] The width of the upper clamping plate 107 is equal to the width of the lower clamping plate 1011, and the radius of the holes in the upper clamping plate 107 and the lower clamping plate 1011 is equal to the radius of the holes in the machine body 1. Workers can align the upper clamping plate 107 and the lower clamping plate 1011 without additional calibration, simplifying the assembly process and reducing human error.
[0037] The limiting plate 1012 is located on the displacement trajectory of the upper clamping plate 107 and the lower clamping plate 1011. The bottom of the upper clamping plate 107 is located above the top of the limiting plate 1012, and the top of the lower clamping plate 1011 is located at the bottom of the limiting plate 1012. The limiting plate 1012 ensures that the upper clamping plate 107 and the lower clamping plate 1011 will not be excessively squeezed when closed by physical blocking, so as to avoid equipment deformation or seal failure due to excessive pressure.
[0038] For example, such as Figure 1-6 As shown, when testing is required, the operator controls the testing device 7 by pressing button 9. The operator aligns the pipe with the hole in the housing 101 at the pipe to be tested. The operator controls the motor 102 by rotating button 103. The start of motor 102 drives the rotation of threaded rod 104. The rotation of threaded rod 104 drives threaded sleeve one 105 and threaded sleeve two 109 to move vertically. The vertical movement of threaded sleeve one 105 and threaded sleeve two 109, through connecting block one 106 and connecting block two 1010, under the restriction of sliding groove one 108 and limiting plate 1012, drives upper clamping plate 107 and lower clamping plate 1011 to move vertically, clamping the pipe.
[0039] like Figures 1-6 As shown, this invention illustrates an ultrasonic flow meter that is easy to assemble and disassemble in another embodiment of the present invention. The technical solution is largely the same as that of embodiment 1, so only the differences are described. The flow meter includes: a detection sealing mechanism 12, which includes a detection guide hole 121. The detection guide hole 121 is opened on the circumferential surface of the hole in the housing 101. A slide rail 122 is provided at the end of the detection guide hole 121 away from the housing 101. A slider 123 is slidably connected inside the slide rail 122. A baffle 124 is fixedly connected to the side of the slider 123. A second slide groove 125 is opened inside the housing 101. A sealing plate 126 is slidably connected inside the second slide groove 125.
[0040] In some examples, the following are also provided: two sliders 123 and two slide rails 122 are provided, and they are symmetrical to each other along the vertical central axis of the detection guide hole 121; two slide grooves 125 are provided, and they are symmetrical to each other along the vertical central axis of the sealing plate 126, so as to ensure that the force on both sides of the sealing plate 126 is evenly distributed and to avoid problems such as the sealing plate 126 tilting due to uneven force.
[0041] The end of the detection guide hole 121 away from the housing 101 is located on the displacement trajectory of the slider 123, and the end of the detection guide hole 121 away from the housing 101 is located to the left of the slider 123, so that the fluid can flow into the detection guide hole 121 in the sealed space.
[0042] The top of the baffle 124 is located at the bottom of the sealing plate 126. The width of the baffle 124 is greater than the width of the sealing plate 126. The baffle 124 is wider than the sealing plate 126, so that the sealing plate 126 can be completely blocked by the baffle 124 during the falling process, so that the baffle 124 can maintain the sealing function of the sealing plate 126 when it does not move to the appropriate position.
[0043] The top of the sealing plate 126 is located above the hole in the housing 101. The width of the sealing plate 126 is greater than the diameter of the hole in the housing 101. The sealing plate 126 is wider than the diameter of the hole in the housing 101, which can completely cover the hole in the housing 101 without leaving any gaps, preventing fluid from leaking out from the edge of the hole and ensuring the tightness of the seal.
[0044] For example, such as Figure 1-6 As shown, after the disassembly and clamping mechanism 10 has finished operating, the fluid enters the sealing area. Due to the action of the sealing plate 126, the fluid flows in through the detection guide hole 121 and is squeezed by the pressure on the baffle 124. Under the restriction of the slide rail 122, the baffle 124 is moved horizontally. The horizontal linear displacement of the baffle 124 causes the sealing plate 126 to fall under the action of gravity and the slide groove 125. The fluid flows into the detection device 7 through the hole, realizing the sealing detection treatment of the fluid.
[0045] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
