Description

An ultrasonic heat meter that does not require shutdown or maintenance Technical Field

[0001] The invention relates to the technical field of instruments and meters, in particular to an ultrasonic heat meter which does not require shutdown for maintenance. Background Art

[0002] Ultrasonic heat meters use ultrasonic waves to measure flow and display the heat energy released or absorbed by water flowing through a heat exchange system. They use two sensors to measure physical quantities—the heat carrier flow rate and the inlet and outlet temperatures—and then perform density and enthalpy compensation and integral calculations to determine the calorific value. When ultrasonic waves propagate through a fluid, the fluid's flow causes a time difference in the propagation speed of the ultrasonic signal. The magnitude of this time difference is directly proportional to the fluid's flow rate. This allows for fluid flow measurement and is widely used in heat exchange stations and other applications.

[0003] After long-term use, impurities will accumulate inside the ultrasonic heat meter, affecting the emission and collection of ultrasonic signals. Therefore, it needs to be disassembled and maintained regularly. However, the existing ultrasonic heat meters need to shut down the valves of the heat network of the heat exchange station every time they are disassembled and maintained to prevent the fluid in the pipeline from spraying out during disassembly. Each shutdown will make the heat network temporarily unusable, affecting normal operation. Therefore, it is necessary to develop an ultrasonic heat meter that does not need to be shut down during disassembly to ensure normal operation.

[0041] In order to make the objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0042] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0043] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0044] Example 1

[0045] 1-3 , which is a first embodiment of the present invention, provides an ultrasonic heat meter that does not require shutdown or maintenance, and can achieve the effect of installation and use of the heat meter body 101. The heat meter includes: a measuring component 100 and a connecting component 200. By setting the connecting component 200, the heat meter can be docked with the fluid pipeline for installation, and the measuring component 100 can be set to detect the fluid flow in the pipeline.

[0046] Specifically, the measurement assembly 100 includes a heat meter body 101, a mounting portion 102 disposed at the bottom of the heat meter body 101, and an ultrasonic probe 103 disposed at the bottom of the heat meter body 101. The ultrasonic probe 103 can transmit or receive ultrasonic signals. When ultrasonic waves propagate through a fluid, the fluid flow causes a time difference in the propagation speed of the ultrasonic signal. The magnitude of this time difference is proportional to the fluid flow rate, thereby measuring the fluid flow rate.

[0047] Furthermore, the connecting assembly 200 is connected to the bottom of the mounting portion 102 and includes a docking portion 201 disposed at the bottom of the mounting portion 102 and adapted to the mounting portion 102, a connecting pipe 202 disposed on one side of the docking portion 201, and an acoustic channel 203 disposed on the side of the connecting pipe 202 and adapted to the ultrasonic probe 103. The connecting pipe 202 is docked with the fluid pipeline and installed, ensuring that the flow direction of the fluid is consistent with the flow direction calibrated on the connecting pipe 202. The ultrasonic probe 103 needs to be installed in the acoustic channel 203 so that the ultrasonic probes 103 on both sides are aligned with the acoustic channel 203 to facilitate the transmission and reception of ultrasonic signals.

[0048] The mounting portion 102 includes a connecting plate 102a disposed at the bottom of the heat meter body 101, a hollowed-out mounting sleeve 102b disposed at the bottom of the connecting plate 102a, a first slot 102c extending through the side of the mounting sleeve 102b, and a positioning member 102d disposed on the side wall of the mounting sleeve 102b. Align the positioning member 102d on the side wall of the mounting sleeve 102b with the positioning slot 102e on the side wall of the connecting post 201a, and then insert the mounting sleeve 102b at the bottom of the heat meter body 101 onto the connecting post 201a to facilitate installation and positioning.

[0049] Preferably, the docking portion 201 includes a connecting post 201a disposed on the sidewall of the connecting pipe 202 and mating with the mounting sleeve 102b, a second slot 201b formed on the side of the connecting post 201a and mating with the first slot 102c, and a positioning groove 102e formed on the sidewall of the connecting post 201a and mating with the positioning member 102d. The mounting sleeve 102b and the connecting post 201a can be fixedly connected by coupling the first slot 102c with the second slot 201b.

[0050] During use, first dock and install the connecting pipe 202 with the fluid pipe, and ensure that the flow direction of the fluid is consistent with the calibrated flow direction of the connecting pipe 202 to avoid affecting the measurement results. Then align the positioning piece 102d on the side wall of the installation sleeve 102b with the positioning groove 102e on the side wall of the connecting column 201a, and then plug the installation sleeve 102b at the bottom of the heat meter body 101 onto the connecting column 201a, and then install the ultrasonic probe 103 at the bottom of the heat meter body 101 into the sound wave channel 203, so that the ultrasonic probes 103 on both sides are aligned with the sound wave channel 203, which facilitates the transmission and reception of ultrasonic signals and performs flow measurement when the fluid passes through the connecting pipe 202.

[0051] In summary, by setting up the measuring component 100 and the connecting component 200 for use together, by setting up the connecting component 200, it can be docked and installed with the fluid pipeline, and by setting up the measuring component 100 to detect the fluid flow in the pipeline, the installation and use of the heat meter body 101 can be realized, solving the problem of inconvenience in measuring the fluid flow.

[0052] Example 2

[0053] 4-8 , a second embodiment of the present invention is shown. Unlike the previous embodiment, this embodiment provides a cable 104 and a storage portion 105 , which solves the problem of installation and fixation of the heat meter body 101 and the problem of the cable 104 of the ultrasonic probe 103 being too long and easily damaged.

[0054] Specifically, the measurement assembly 100 also includes a cable 104 connecting the bottom of the heat meter body 101 and the ultrasonic probe 103, and a storage portion 105 disposed between the bottom of the heat meter body 101 and the ultrasonic probe 103 and adapted to accommodate the cable 104. The cable 104 is designed to be longer for ease of installation and use. After installation, any excess cable 104 can be stored within the storage portion 105 to prevent damage.

[0055] Furthermore, the storage portion 105 includes a slide groove 105a opened at the bottom of the connecting plate 102a and matching the cable 104, a slider 105b slidably connected in the slide groove 105a, a connecting rod 105c arranged at the bottom of the slider 105b and matching the first slot 102c and the second slot 201b respectively, a storage groove 105d arranged inside the slider 105b and the connecting rod 105c and matching the cable 104, a steering column 105e rotatably connected at the starting point and corner of the storage groove 105d and matching the cable 104, and a storage block 105f arranged on one side of the ultrasonic probe 103 and matching the storage groove 105d. When installing the ultrasonic probe 103, first insert the storage block 105f on one side of the ultrasonic probe 103 into the storage groove 105d, so that the cable 104 that is too long and extends out can be stored in the storage groove 105d. When the connecting rod 105c moves, the slider 105b slides along the slide groove 105a. Since the end of the cable 104 is fixed, the movement of the slider 105b and the connecting rod 105c will pull the cable 104. The cable 104 is gradually straightened in the storage groove 105d through the steering column 105e at the starting point and the corner until the connecting rod 105c moves to the maximum limit and the cable 104 is just taut. The cable 104 is always in the storage groove 105d inside the connecting rod 105c, which is convenient for protection.

[0056] The ultrasonic probe 103 includes a probe body 103a, located at its end for transmitting and receiving signals; a cone 103b located on one side of the probe body 103a; and positioning rings 103c located on either side of a receiving block 105f and aligned with the acoustic channel 203. The movement of the connecting rod 105c drives the ultrasonic probe 103 deeper into the acoustic channel 203, causing the positioning ring 103c to compress a first spring 204b until the cone 103b on the side of the probe body 103a presses against a sealing gasket 204a. The sealing gasket 204a is preferably made of rubber and deforms under compression, thereby filling the gap between the cone 103b and the sealing gasket 204a, forming a seal. During installation, the first spring 204b is compressed, and during disassembly, the reaction force of the first spring 204b facilitates removal of the ultrasonic probe 103.

[0057] Preferably, the connecting assembly 200 also includes a connecting portion 204 arranged on one side of the acoustic channel 203, the connecting portion 204 includes a sealing gasket 204a arranged on the inner wall of the acoustic channel 203 and matching the cone 103b, a first spring 204b arranged on one side of the sealing gasket 204a and matching the positioning ring 103c, an extrusion ring 204c threadedly connected to the outer wall of the acoustic channel 203, and a notch 204d opened on the outer wall of the acoustic channel 203 and on one side of the extrusion ring 204c and matching the connecting rod 105c. The ultrasonic probe 103 slides on the inner wall of the sound wave channel 203 through the positioning ring 103c. The movement of the ultrasonic probe 103 drives the connecting rod 105c and the slider 105b to slide along the direction of the slide groove 105a. When the connecting rod 105c passes through the notch 204d on one side of the extrusion ring 204c, the extrusion ring 204c is rotated to slide on the thread of the outer wall of the sound wave channel 203. After the extrusion ring 204c moves, the notch 204d makes a circular motion and is misaligned with the connecting rod 105c, so that the extrusion ring 204c can squeeze and push the connecting rod 105c.

[0058] In Example 1, after the installation sleeve 102b at the bottom of the heat meter body 101 is plugged into the connecting column 201a, when installing the ultrasonic probe 103, first insert the storage block 105f on one side of the ultrasonic probe 103 into the storage groove 105d, so that the over-extended cable 104 is stored in the storage groove 105d, then rotate the extrusion ring 204c to align the notch 204d on one side of the extrusion ring 204c with the notch 204d on the outer wall of the sound wave channel 203, then keep the connecting rod 105c aligned with the notch 204d, and insert the ultrasonic probe 103 into the ultrasonic channel 203. In the sound wave channel 203, the ultrasonic probe 103 slides along the inner wall of the sound wave channel 203 through the positioning ring 103c. The movement of the ultrasonic probe 103 drives the connecting rod 105c and the slider 105b to slide along the direction of the slide groove 105a. After the connecting rod 105c passes through the notch 204d on one side of the extrusion ring 204c, the extrusion ring 204c is rotated to slide along the thread of the outer wall of the sound wave channel 203. After the extrusion ring 204c moves, the notch 204d makes a circular motion and is misaligned with the connecting rod 105c, so that the extrusion ring 204c can squeeze and push the connecting rod 105c.

[0059] During the movement of the connecting rod 105c, the ultrasonic probe 103 is driven to penetrate into the acoustic channel 203, and the positioning ring 103c compresses the first spring 204b until the cone 103b on one side of the probe body 103a squeezes the sealing gasket 204a. The connecting rod 105c moves to the maximum extent to be blocked by the acoustic channel 203, and is fixed by the squeezing of the squeezing ring 204c. The sealing gasket 204a is preferably made of rubber, which will deform under squeezing, thereby filling the gap between the cone 103b and the sealing gasket 204a to form a seal.

[0060] During the movement of the connecting rod 105c, the first slot 102c and the second slot 201b are gradually connected and limited until the installation sleeve 102b is connected to the connecting column 201a, so that the heat meter body 101 is installed and fixed;

[0061] In addition, when the connecting rod 105c moves, the slider 105b slides along the slide groove 105a. Since the end of the cable 104 is fixed, the movement of the slider 105b and the connecting rod 105c will pull the cable 104. The cable 104 is gradually straightened in the storage groove 105d through the steering column 105e at the starting point and the corner until the connecting rod 105c moves to the maximum limit. The cable 104 is just taut, and the cable 104 is always in the storage groove 105d inside the connecting rod 105c for easy protection.

[0062] In summary, by setting the cable 104 and the storage part 105 for use together, the installation sleeve 102b and the connecting column 201a can be connected and fixed while the ultrasonic probe 103 is installed and sealed, and the excessively long cable 104 can be stored in the storage groove 105d and straightened for easy protection, thereby solving the problems of installation and fixation of the heat meter body 101 and the problem of the cable 104 of the ultrasonic probe 103 being too long and easy to be damaged.

[0063] Example 3

[0064] 8-13 , which is a third embodiment of the present invention, is different from the previous embodiment in that this embodiment provides an anti-seepage portion 301 , a sealing portion 302 and an adjusting portion 303 , which solves the problem that the fluid valve needs to be shut down every time the ultrasonic heat meter is disassembled for maintenance, affecting normal operation.

[0065] Specifically, the sealing assembly 300 includes an impermeable portion 301 disposed inside the connecting pipe 202 near the connecting column 201a, a blocking portion 302 disposed on the inner wall of the connecting pipe 202 and aligned with the acoustic channel 203, and an adjusting portion 303 disposed on one side of the connecting column 201a and aligned with the blocking portion 302. A blocking plate 302b passing through the blocking portion 302 blocks the acoustic channel 203 to form a seal, and the adjusting portion 303 allows adjustment of the blocking condition.

[0066] Furthermore, the anti-seepage portion 301 includes a connecting ring 301a symmetrically arranged inside the connecting pipe 202, a sealing groove 301b provided on one side of the connecting ring 301a, a first rotation groove 301c provided on the other side of the connecting ring 301a, and a sealing ring 301d connected to the inner wall of the connecting pipe 202 and matching the sealing groove 301b. The sealing groove 301b and the sealing ring 301d cooperate to seal the opening formed by the first rotation groove 301c of the adjusting portion 303, preventing leakage.

[0067] The sealing portion 302 includes a sealing groove 302a provided on the inner wall of the connecting pipe 202 near the acoustic channel 203, a sealing plate 302b rotatably connected to and in contact with the sealing groove 302a, a rotating ring 302c provided on the sealing plate 302b near the connecting ring 301a and matching the first rotating groove 301c, and a connecting groove 302d provided on the sealing plate 302b near the acoustic channel 203. Before disassembling the heat meter body 101, the connecting groove 302d is misaligned with the acoustic channel 203 by rotating the adjusting rod 303c. The acoustic channel 203 is then sealed by the sealing plate 302b to prevent the fluid from being ejected when the ultrasonic probe 103 is disassembled, thereby preventing the normal flow of the fluid and eliminating the need to shut down the fluid valve.

[0068] Among them, the blocking part 302 also includes a tooth groove 302c-1 distributed in an array on the outside of the rotating ring 302c; the adjusting part 303 includes a second rotating groove 303a opened at the connection between the connecting pipe 202 and the connecting column 201a and communicated with the positioning groove 102e, a gear 303b rotatably connected in the second rotating groove 303a and matched with the tooth groove 302c-1, an adjusting rod 303c passing through and connected between the connecting column 201a and the gear 303b, a limiting protrusion 303d arranged on the side of the adjusting rod 303c close to the gear 303b, and a limiting groove 303e arranged inside the gear 303b and matching the limiting protrusion 303d; the adjusting rod 303c and the connecting column 201a are threadedly connected, and limiting baffles 303c-1 are provided at both ends of the adjusting rod 303c. The rotation of the gear 303b will drive the rotating ring 302c to rotate by engaging with the tooth groove 302c-1 on one side of the rotating ring 302c, and the rotation of the rotating ring 302c will drive the sealing plate 302b to rotate. After the heat meter body 101 is installed, the connecting groove 302d of the sealing plate 302b should be aligned with the sound wave channel 203 by rotating the adjusting rod 303c, without affecting the transmission and reception of ultrasonic signals.

[0069] Preferably, the positioning member 102d includes a connecting block 102d-1 arranged on the side of the mounting sleeve 102b close to the positioning groove 102e, a track groove 102d-2 arranged at the bottom of the connecting block 102d-1, a telescopic block 102d-3 slidably connected in the track groove 102d-2, a second spring 102d-4 connected between the telescopic block 102d-3 and the side wall of the track groove 102d-2, and a positioning block 102d-5 connected to the bottom of the telescopic block 102d-3 and matching the positioning groove 102e; a chamfer is provided on the upper side of the positioning block 102d-5. During installation, the positioning block 102d-5 protrudes downward from the bottom of the installation sleeve 102b, making it convenient to align the positioning piece 102d with the positioning groove 102e. The adjusting rod 303c is rotated, and the adjusting rod 303c drives the gear 303b to rotate through the limiting protrusion 303d on one side. The rotation of the gear 303b will squeeze the chamfered angle on the upper side of the positioning block 102d-5, generating a horizontal component force, so that the positioning block 102d-5 pushes the telescopic block 102d-3 to compress the second spring 102d-4 into the track groove 102d-2, and resets through the second spring 102d-4 when the gear 303b loses its extrusion, without affecting the rotation of the gear 303b.

[0070] During installation, the positioning block 102d-5 protrudes downward from the bottom of the installation sleeve 102b, making it easy to align the positioning piece 102d with the positioning groove 102e. The installation sleeve 102b is inserted into the connecting column 201a and then moved downward. The positioning block 102d-5 moves downward in the positioning groove 102e following the installation sleeve 102b. The flat surface at the bottom of the positioning block 102d-5 contacts the gear 303b, which will push the gear 303b to rotate. However, the positioning block 102d-5 itself will not slide relative to the track groove 102d-2 through the telescopic block 102d-3. The adjusting rod 303c is rotated, and the adjusting rod 303c drives the gear 303b to rotate through the limiting protrusion 303d on one side. The rotation of the gear 303b squeezes the chamfered angle on the upper side of the positioning block 102d-5, generating a horizontal component of force, so that the positioning block 102d-5 pushes the telescopic block 102d-3 to compress the second spring 102d-4 into the track groove 102d-2, and resets through the second spring 102d-4 when the squeezing of the gear 303b is lost, without affecting the rotation of the gear 303b.

[0071] The rotation of the gear 303b will drive the rotating ring 302c to rotate by meshing with the tooth groove 302c-1 on one side of the rotating ring 302c, and the rotation of the rotating ring 302c will drive the sealing plate 302b to rotate. The communicating grooves 302d on both sides of the sealing plate 302b are arranged symmetrically with the center. Therefore, the rotation of the rotating ring 302c can adjust the communicating grooves 302d of the sealing plates 302b on both sides at the same time. After the heat meter body 101 is installed, the adjusting rod 303c should be rotated to make the communicating grooves 302d of the sealing plate 302b correspond to the sound wave channel 203, which does not affect the transmission and reception of ultrasonic signals. Before the heat meter body 101 needs to be disassembled, the adjusting rod 303c should be rotated to make the communicating grooves 302d and the sound wave channel 203 misaligned, and the sound wave channel 203 is blocked and sealed by the sealing plate 302b. In this way, when the ultrasonic probe 103 is disassembled again, the fluid in the pipeline will not be sprayed out, and the normal circulation of the fluid will not be affected, and the fluid valve does not need to be closed.

[0072] The adjusting rod 303c is threadedly connected to the connecting column 201a. When the adjusting rod 303c is rotated, it will also move axially, which facilitates the limiting baffles 303c-1 at both ends to squeeze and fix the connecting column 201a, thereby fixing the position of the blocking plate 302b.

[0073] The disassembly steps of the ultrasonic probe 103 and the heat meter body 101 are opposite to the above-mentioned installation steps and will not be repeated here.

[0074] In summary, by setting the anti-seepage part 301, the sealing part 302 and the adjustment part 303 in conjunction with each other, the sound wave channel 203 can be sealed by the sealing plate 302b of the sealing part 302, so that when the ultrasonic probe 103 is disassembled, the fluid in the pipeline will not be sprayed out, and the normal circulation of the fluid will not be affected. There is no need to close the fluid valve, which solves the problem that the fluid valve needs to be closed every time the ultrasonic heat meter is disassembled and maintained, affecting normal operation.
