Description

Technical Field

[0001] The present invention belongs to the technical field of detection, specifically relates to the technical field of detection using ultrasonic waves, and particularly relates to a monitoring method, system, non-transitory readable storage medium, program product and detection device for the water supply pipeline of a power converter station. Background Art

[0002] Firefighting pipelines are arranged in converter stations. When it is necessary to detect the firefighting pipelines, real-time detection is required. However, due to the particularity of the firefighting pipelines, it is not possible to drill holes to install sensors or reserve detection holes at preset positions. Also, due to the particularity of the converter station, the non-contact form of electromagnetic detection will be affected and interfered by the converter. When using ultrasonic detection, the ultrasonic waves will be affected by the bubbles in the liquid in the pipeline.

[0003] Therefore, due to the technical problem that the ultrasonic waves are affected by the bubbles in the liquid in the pipeline, resulting in inaccurate flow velocity detection, it is necessary to design a monitoring method, system, non-transitory readable storage medium, program product and detection device for the water supply pipeline of a power converter station.

[0004] It should be noted that the above information disclosed in this background art section is only used to understand the background art of the concept of this application. Therefore, it is not considered that the above description constitutes the information of the prior art. Summary of the Invention

[0005] The embodiments of the present disclosure at least provide a monitoring method, system, non-transitory readable storage medium, program product and detection device for the water supply pipeline of a power converter station.

[0006] In a first aspect, the embodiments of the present disclosure provide a monitoring method for the water supply pipeline of a power converter station, including: A detection device is set on the pipeline. Three ultrasonic mechanisms are sequentially arranged in the detection device along the flowing direction of the liquid in the pipeline, and the liquid first passes through the ultrasonic mechanism at the head position. The control module adjusts the power of the ultrasonic waves emitted by the remaining two ultrasonic mechanisms according to the detection result of the ultrasonic mechanism at the tail position, so that the liquid meets the required detection environment. After the liquid meets the detection environment, the control module controls the ultrasonic mechanism at the middle position to emit ultrasonic waves to detect the flow velocity of the liquid.

[0007] In an optional implementation manner, the method of adjusting the power of the ultrasonic waves emitted by the remaining two ultrasonic mechanisms by the control module according to the detection result of the ultrasonic mechanism at the tail position includes: When the control module determines that there are bubbles in the liquid, it first controls the ultrasonic mechanism at the head position to emit ultrasonic waves. If it still determines that there are bubbles, the ultrasonic power emitted by the ultrasonic mechanism at the head position is increased by a first preset power. After each increase in the ultrasonic power emitted by the ultrasonic mechanism at the head position, it is determined whether there are bubbles until it is determined that there are no bubbles or the power of the ultrasonic waves emitted by the ultrasonic mechanism at the head position reaches the preset maximum value. At this time, the power of the ultrasonic waves emitted by the ultrasonic mechanism at the head position is no longer increased.

[0008] In an alternative embodiment, the method for the control module to determine whether there are bubbles in the liquid includes: The control module controls the ultrasonic mechanism at the tail position to emit and receive ultrasonic waves, and then determines whether the ratio of the received ultrasonic power to the emitted ultrasonic power is less than a first threshold. If it is less than the first threshold, it is determined that there are bubbles in the liquid in the pipeline at the corresponding position; otherwise, it is determined that there are no bubbles.

[0009] In an alternative embodiment, after it is determined that there are no bubbles, the control module controls the ultrasonic power emitted by the ultrasonic mechanism at the head position to be reduced by a second preset power, and then determines whether there are bubbles. If there are no bubbles, the ultrasonic power emitted by the ultrasonic mechanism at the head position continues to be reduced by the second preset power until it is determined that there are bubbles. At this time, the ultrasonic power emitted by the ultrasonic mechanism at the head position is the power corresponding to the ultrasonic waves emitted by the ultrasonic mechanism at the head position when it was last determined that there were no bubbles, so that there are no bubbles in the liquid, enabling the liquid to meet the required detection environment, and controlling the ultrasonic mechanism at the middle position to emit ultrasonic waves to detect the liquid flow rate; The first preset power is greater than the second preset power.

[0010] In an alternative embodiment, when the power of the ultrasonic waves emitted by the ultrasonic mechanism at the head position reaches the preset maximum value, if it is still determined that there are bubbles at this time, the control module controls the ultrasonic mechanism at the middle position to emit ultrasonic waves, and then determines again whether there are bubbles. If there are bubbles, the ultrasonic power emitted by the ultrasonic mechanism at the middle position is increased by a third preset power until it is determined that there are no bubbles. The power of the ultrasonic waves emitted by the ultrasonic mechanism at the head position and the ultrasonic mechanism at the middle position at this time is maintained, so that there are no bubbles in the liquid, enabling the liquid to meet the required detection environment, and detecting the liquid flow rate by increasing the preset proportional power of the ultrasonic waves emitted by the ultrasonic mechanism at the middle position again; The plane formed by the ultrasonic waves emitted by the two ultrasonic mechanisms at the head position and the tail position is parallel to the vertical cross-section of the horizontally arranged pipeline; The plane formed by the ultrasonic waves emitted by the ultrasonic mechanism at the middle position is perpendicular to the vertical cross-section of the horizontally arranged pipeline, and the range corresponding to the ultrasonic waves emitted by the ultrasonic mechanism at the middle position contacts the range corresponding to the ultrasonic waves emitted by the ultrasonic mechanism at the head position.

[0011] In a second aspect, an embodiment of the present disclosure further provides a monitoring system for a water supply pipeline of a power converter station, including: An adjustment module configured to adjust the power of ultrasonic waves emitted by the remaining two ultrasonic mechanisms according to the detection result of the ultrasonic mechanism at the tail position, so that the liquid meets the required detection environment; A flow rate module configured to emit ultrasonic waves through the ultrasonic mechanism at the middle position to detect the flow rate of the liquid after the liquid meets the detection environment.

[0012] In a third aspect, an embodiment of the present disclosure further provides a non-transitory readable storage medium, on which a program / instructions are stored, and when the program / instructions are executed by a processor, the steps of the above-mentioned monitoring method for the water supply pipeline of the power converter station are implemented.

[0013] In a fourth aspect, an embodiment of the present disclosure further provides a program product containing instructions, and when the instructions are run on a device, the device is caused to execute the steps of the above-mentioned monitoring method for the water supply pipeline of the power converter station.

[0014] In a fifth aspect, an embodiment of the present disclosure further provides a detection device for a monitoring system of a water supply pipeline of a power converter station, including: A moving mechanism sleeved on the pipeline, and three ultrasonic mechanisms are sequentially arranged on a surface of the moving mechanism close to the pipeline along the liquid flow direction in the pipeline, and the liquid first passes through the ultrasonic mechanism at the head position; The ultrasonic mechanism is electrically connected to a control module, and the control module is configured to detect the liquid flow rate in the pipeline through the ultrasonic mechanism by using the above-mentioned monitoring method for the water supply pipeline of the power converter station.

[0015] In an optional implementation manner, the moving mechanism includes: an upper arc plate and a lower arc plate; An accommodation area is formed between the upper arc plate and the lower arc plate to sleeved the upper arc plate and the lower arc plate on the pipeline; The upper arc plate and the lower arc plate are directly connected by bolts; Three upper strip-shaped grooves are formed on a surface of the upper arc plate facing the pipeline along the liquid flow direction in the pipeline, the length directions of the head and tail two upper strip-shaped grooves are arranged along the circumferential direction of the inner wall of the upper arc plate, and the length direction of the middle position upper strip-shaped groove is arranged along the length direction of the upper arc plate; Lower strip-shaped grooves corresponding to the upper strip-shaped grooves are formed on a surface of the lower arc plate facing the pipeline; There are gaps between both ends of the upper arc plate and the lower arc plate in the circumferential direction and the outer wall of the pipeline, and shock-absorbing materials are filled in the gaps.

[0016] In an alternative embodiment, the ultrasonic mechanism includes an ultrasonic generator and an ultrasonic receiver electrically connected to the control module; The ultrasonic generator is disposed inside the upper strip-shaped groove, and the control module controls the ultrasonic generator to emit ultrasonic waves; The ultrasonic receiver is disposed inside the lower strip-shaped groove, and the control module controls the ultrasonic receiver to receive the ultrasonic waves emitted by the corresponding ultrasonic generator.

[0017] The area where the ultrasonic generator emits ultrasonic waves is restricted by the upper strip-shaped groove; The plane formed by the ultrasonic waves emitted by the two ultrasonic generators at the head position and the tail position is parallel to the vertical cross-section of the horizontally arranged pipeline; The plane formed by the ultrasonic waves emitted by the ultrasonic generator at the middle position is perpendicular to the vertical cross-section of the horizontally arranged pipeline, and the range corresponding to the ultrasonic waves emitted by the ultrasonic generator at the middle position is in contact with the range corresponding to the ultrasonic waves emitted by the ultrasonic generator at the head position.

[0018] The beneficial effect of the present invention is that the method for monitoring the water supply pipeline of the power converter station includes: setting a detection device on the pipeline, and three ultrasonic mechanisms are sequentially arranged in the detection device along the liquid flow direction in the pipeline, and the liquid first passes through the ultrasonic mechanism at the head position; according to the detection result of the ultrasonic mechanism at the tail position, the control module adjusts the power of the ultrasonic waves emitted by the remaining two ultrasonic mechanisms so that the liquid meets the required detection environment; after the liquid meets the detection environment, the control module controls the ultrasonic mechanism at the middle position to emit ultrasonic waves to detect the flow rate of the liquid, thereby realizing that when detecting the flow rate of the liquid in the pipeline by ultrasonic waves, the bubbles in the liquid in the pipeline are first eliminated, so that the ultrasonic detection of the flow rate can be more accurate.

[0026] When a converter station arranges fire pipelines and real-time detection is required during the inspection of fire pipelines, due to the particularity of fire pipelines, in order to ensure the strength of fire pipelines, sensors cannot be installed by drilling holes or detection holes cannot be reserved at preset positions, and only non-contact detection methods can be used for detection. Also, due to the particularity of the converter station, the non-contact form of electromagnetic detection will be interfered by the converter station, resulting in inaccurate flow velocity detection. The inventor found that when ultrasonic waves are used to detect the liquid flow velocity in the pipeline, the ultrasonic waves will be affected by the bubbles in the liquid, resulting in inaccurate detected flow velocity.

[0027] Regarding the defects existing in the above solutions, they are all the results obtained by the inventor through practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure by the present disclosure for the above problems should all be the contributions made by the inventor during the disclosure process of the present disclosure.

[0028] It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0029] The following will describe in detail some embodiments of the present invention with reference to the drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0030] As Figure 1 shown, at least one disclosed embodiment provides a method for monitoring the water supply pipeline of a power converter station, including: setting a detection device on pipeline 2, and three ultrasonic mechanisms are sequentially arranged in the detection device along the liquid flow direction in pipeline 2, and the liquid first passes through the ultrasonic mechanism at the head position; according to the detection result of the ultrasonic mechanism at the tail position by the control module, adjusting the power of the ultrasonic waves emitted by the remaining two ultrasonic mechanisms so that the liquid meets the required detection environment; after the liquid meets the detection environment, the control module controls the ultrasonic mechanism at the middle position to emit ultrasonic waves to detect the flow velocity of the liquid, thereby realizing that when detecting the liquid flow velocity in pipeline 2 by ultrasonic waves, the bubbles in the liquid in pipeline 2 are first eliminated, so that the ultrasonic wave detection of the flow velocity can be more accurate.

[0031] In this embodiment, the control module can adjust the power of the ultrasonic mechanism.

[0032] In this embodiment, since the ultrasonic waves will be affected by the bubbles in the liquid when using ultrasonic wave detection, the bubbles in the liquid are eliminated by adjusting the respective powers of the corresponding ultrasonic mechanisms, so that the liquid meets the required detection environment, that is, there are no bubbles in the liquid; for example, when there are bubbles in the liquid, the power of the corresponding ultrasonic mechanism is increased to eliminate the bubbles.

[0033] In this embodiment, the liquid flow direction is as Figure 6China F as shown

[0034] As Figure 6 shown, in this embodiment, the ultrasonic mechanism at the head position can emit ultrasonic waves to eliminate the bubbles in the liquid in the pipeline 2; the ultrasonic mechanism at the middle position can emit ultrasonic waves to detect the flow rate of the liquid in the pipeline 2; the ultrasonic mechanism at the tail position can emit ultrasonic waves to detect the elimination effect of the bubbles in the liquid in the pipeline 2.

[0035] In this embodiment, the liquid in the pipeline 2 first passes through the ultrasonic waves emitted by the ultrasonic mechanism at the head position, then passes through the ultrasonic waves emitted by the ultrasonic mechanism at the middle position, and finally passes through the ultrasonic waves emitted by the ultrasonic mechanism at the tail position. The ultrasonic mechanism is located outside the pipeline 2.

[0036] In this embodiment, after the ultrasonic generator in the ultrasonic mechanism emits ultrasonic waves, the ultrasonic waves are received by the ultrasonic receiver after passing through the pipeline 2. If there are bubbles in the liquid, the power of the ultrasonic waves received by the ultrasonic receiver will be smaller than the power of the ultrasonic waves emitted by the ultrasonic generator. Therefore, the ultrasonic mechanism at the tail position can judge whether there are bubbles in the liquid according to the power ratio of the received and emitted ultrasonic waves. A first threshold can be set in the control module. When the power ratio of the received and emitted ultrasonic waves by the ultrasonic mechanism at the tail position is less than the first threshold, it is judged that there are still bubbles in the liquid.

[0037] In an optional implementation manner, the method for the control module to adjust the power of the ultrasonic waves emitted by the remaining two ultrasonic mechanisms according to the detection result of the ultrasonic mechanism at the tail position includes: when the control module judges that there are bubbles in the liquid, first control the ultrasonic mechanism at the head position to emit ultrasonic waves. If it is still judged that there are bubbles, the power of the ultrasonic waves emitted by the ultrasonic mechanism at the head position is increased by a first preset power. After each increase in the power of the ultrasonic waves emitted by the ultrasonic mechanism at the head position, it is judged whether there are bubbles until it is judged that there are no bubbles or the power of the ultrasonic waves emitted by the ultrasonic mechanism at the head position reaches the preset maximum value. At this time, the power of the ultrasonic waves emitted by the ultrasonic mechanism at the head position no longer increases.

[0038] In this embodiment, when the detection result of the ultrasonic mechanism at the tail position is that there are bubbles in the liquid, the control module can first control the ultrasonic mechanism at the head position to emit ultrasonic waves at a preset fixed power. At this time, the ultrasonic mechanism at the tail position continues to judge whether the bubbles are eliminated. If not, the power of the ultrasonic waves emitted by the ultrasonic mechanism at the head position is increased by a first preset power, and then it is judged again whether the bubbles are eliminated, and so on, until it is judged that there are no bubbles or the power of the ultrasonic waves emitted by the ultrasonic mechanism at the head position reaches the preset maximum value.

[0039] In an alternative embodiment, the method for the control module to determine whether there are bubbles in the liquid includes: the control module controls the ultrasonic mechanism at the tail position to emit and receive ultrasonic waves, and then determines whether the ratio between the received ultrasonic power and the emitted ultrasonic power is less than a first threshold. If it is less than the first threshold, it is determined that there are bubbles in the liquid in the pipeline 2 at the corresponding position; otherwise, it is determined that there are no bubbles.

[0040] In this embodiment, the ultrasonic receiver can calculate the actual received power, that is, the power corresponding to the received ultrasonic wave, according to the intensity or energy of the received ultrasonic signal and in combination with the relationship between the transmission power and the distance.

[0041] In an alternative embodiment, after it is determined that there are no bubbles, the control module controls the ultrasonic mechanism at the head position to reduce the emitted ultrasonic power by a second preset power, and then determines whether there are bubbles. If there are no bubbles, the control module continues to reduce the emitted ultrasonic power of the ultrasonic mechanism at the head position by the second preset power until it is determined that there are bubbles. At this time, the emitted ultrasonic power of the ultrasonic mechanism at the head position is the power corresponding to the emitted ultrasonic wave of the ultrasonic mechanism at the head position when it was last determined that there were no bubbles, so that there are no bubbles in the liquid, enabling the liquid to meet the required detection environment, and the control module controls the ultrasonic mechanism at the middle position to emit ultrasonic waves to detect the liquid flow rate; the first preset power is greater than the second preset power.

[0042] In this embodiment, since ultrasonic waves are mechanical energy, it is necessary to minimize this mechanical energy as much as possible to avoid the influence of ultrasonic waves on other sensors, etc. Therefore, after it is determined that there are no bubbles, it is necessary to minimize the power corresponding to the ultrasonic wave emitted by the ultrasonic mechanism at the head position as much as possible. That is, when it is determined that there are no bubbles and the power corresponding to the ultrasonic wave emitted by the ultrasonic mechanism at the head position has not reached the preset maximum value, the control module controls the ultrasonic mechanism at the head position to reduce the second preset power each time on the basis of the current power, so that the power of the ultrasonic wave emitted by the ultrasonic mechanism at the head position gradually decreases. After each reduction, it is determined whether there are bubbles until it is first determined that there are bubbles, indicating that the power of the ultrasonic wave emitted by the ultrasonic mechanism at the head position at this time cannot meet the requirement of eliminating bubbles, while the power of the ultrasonic wave emitted by the ultrasonic mechanism at the head position when it was last determined that there were no bubbles can achieve the elimination of bubbles. Therefore, the control module maintains the power of the ultrasonic wave emitted by the ultrasonic mechanism at the head position at the power of the ultrasonic wave emitted by the ultrasonic mechanism at the head position when it was last determined that there were no bubbles, so that the ultrasonic mechanism at the head position can meet the requirement of bubble elimination with the minimum ultrasonic power. Then, the control module performs flow rate detection through the ultrasonic mechanism at the middle position to achieve accurate flow rate detection.

[0043] In this embodiment, the first preset power is greater than the second preset power, so that when reducing the power of the ultrasonic wave mechanism at the head position, the change amount is small, and the best condition of the power of the ultrasonic wave mechanism at the head position can be found more accurately.

[0044] In this embodiment, since the range corresponding to the ultrasonic wave emitted by the ultrasonic wave mechanism at the middle position contacts the range corresponding to the ultrasonic wave emitted by the ultrasonic wave mechanism at the head position, the ultrasonic powers will be superimposed at the contact position of the two. When there is a sudden increase in bubbles during the detection process, the superimposed power can avoid the influence of the suddenly increased bubbles on the flow velocity detection.

[0045] In an optional implementation manner, when the power of the ultrasonic wave emitted by the ultrasonic wave mechanism at the head position reaches the preset maximum value, if it is still determined that there are bubbles at this time, the control module controls the ultrasonic wave mechanism at the middle position to emit ultrasonic waves, and then determines again whether there are bubbles. If there are bubbles, the power of the ultrasonic wave mechanism at the middle position is increased by a third preset power until it is determined that there are no bubbles, and the powers of the ultrasonic wave mechanisms at the head position and the middle position that emit ultrasonic waves at this time are maintained, so that there are no bubbles in the liquid, making the liquid meet the required detection environment. After the ultrasonic wave emitted by the ultrasonic wave mechanism at the middle position increases the preset proportional power again, the flow velocity of the liquid is detected; the surface formed by the ultrasonic waves emitted by the two ultrasonic wave mechanisms at the head position and the tail position is parallel to the vertical cross-section of the horizontally arranged pipeline 2; the surface formed by the ultrasonic wave emitted by the ultrasonic wave mechanism at the middle position is perpendicular to the vertical cross-section of the horizontally arranged pipeline 2, and the range corresponding to the ultrasonic wave emitted by the ultrasonic wave mechanism at the middle position contacts the range corresponding to the ultrasonic wave emitted by the ultrasonic wave mechanism at the head position.

[0046] In this embodiment, when the power of the ultrasonic wave emitted by the ultrasonic wave mechanism at the head position reaches the preset maximum value, but it is still determined that there are bubbles, it means that the ultrasonic wave mechanism at the head position cannot eliminate the bubbles. At this time, the ultrasonic wave mechanism at the middle position needs to be assisted. Since the range corresponding to the ultrasonic wave emitted by the ultrasonic wave mechanism at the middle position contacts the range corresponding to the ultrasonic wave emitted by the ultrasonic wave mechanism at the head position, the ultrasonic powers will be superimposed at the contact position of the two, increasing the bubble elimination effect.

[0047] As Figure 3 and Figure 6 shown, in this embodiment, the surface formed by the ultrasonic waves emitted by the two ultrasonic wave mechanisms at the head position and the tail position is as shown in Figure 3 the a area. The surface formed by the ultrasonic wave emitted by the ultrasonic wave mechanism at the middle position is as shown in Figure 6 the b area.

[0048] In this embodiment, continuously increase the power of the ultrasonic wave mechanism at the middle position until it is determined that there are no bubbles, indicating that the power of the ultrasonic wave mechanism at the middle position and the power of the ultrasonic wave mechanism at the head position can eliminate the bubbles in the liquid at this time. At this time, maintain the power of both, and continue to increase the power of the ultrasonic wave mechanism at the middle position by a preset ratio, such as 10%, to detect the liquid flow rate while ensuring the effect of bubble elimination and ensuring the accurate detection of the liquid flow rate.

[0049] At least one other disclosed embodiment also provides a monitoring system for the water supply pipeline of a power converter station, including: an adjustment module configured to adjust the power of the ultrasonic wave emitted by the remaining two ultrasonic wave mechanisms according to the detection result of the ultrasonic wave mechanism at the tail position, so that the liquid meets the required detection environment; a flow rate module configured to emit ultrasonic waves through the ultrasonic wave mechanism at the middle position to detect the flow rate of the liquid after the liquid meets the detection environment.

[0050] In this embodiment, the above modules may be virtual modules, and their functional steps may be integrated in the control module.

[0051] At least one other disclosed embodiment also provides a non-transitory readable storage medium, on which a program / instructions are stored, and when the program / instructions are executed by a processor, the steps of the above-mentioned monitoring method for the water supply pipeline of the power converter station are implemented.

[0052] At least one other disclosed embodiment also provides a program product containing instructions, which when the instructions are run on a device, cause the device to execute the steps of the above-mentioned monitoring method for the water supply pipeline of the power converter station.

[0053] As Figure 2 、 Figure 6 As shown in

[0054] As Figure 4 and Figure 5As shown, in an alternative embodiment, the moving mechanism 1 includes: an upper arc-shaped plate 11 and a lower arc-shaped plate 12; an accommodation area is formed between the upper arc-shaped plate 11 and the lower arc-shaped plate 12 so that the upper arc-shaped plate 11 and the lower arc-shaped plate 12 are sleeved on the pipeline 2; the upper arc-shaped plate 11 and the lower arc-shaped plate 12 are directly connected by bolts 14; on the side of the upper arc-shaped plate 11 facing the pipeline 2, three upper strip-shaped grooves 111 are opened along the flowing direction of the liquid in the pipeline 2. The length directions of the head and tail two upper strip-shaped grooves 111 are arranged along the circumferential direction of the inner wall of the upper arc-shaped plate 11, and the length direction of the middle-line position upper strip-shaped groove 111 is arranged along the length direction of the upper arc-shaped plate 11; on the side of the lower arc-shaped plate 12 facing the pipeline 2, lower strip-shaped grooves 121 corresponding to the upper strip-shaped grooves 111 are opened; there are intervals 13 between both ends of the upper arc-shaped plate 11 and the lower arc-shaped plate 12 in the circumferential direction and the outer wall of the pipeline 2, and damping materials are filled in the intervals 13.

[0055] In this embodiment, connecting the upper arc-shaped plate 11 and the lower arc-shaped plate 12 by bolts 14 facilitates the disassembly and assembly of the two, enabling the detection device to be installed at any position on the pipeline 2 and facilitating the movement of the detection device.

[0056] In this embodiment, since there are intervals 13 between both ends of the upper arc-shaped plate 11 and the lower arc-shaped plate 12 in the circumferential direction and the outer wall of the pipeline 2, the upper arc-shaped plate 11 and the lower arc-shaped plate 12 can adapt to pipelines 2 with different diameters, increasing the applicable scenarios of the detection device.

[0057] In this embodiment, the damping material can be silicone rubber, etc., which is used to absorb the ultrasonic waves transmitted along the pipeline 2, and the damping material can assist in fixing the upper arc-shaped plate 11 and the lower arc-shaped plate 12; after absorbing the ultrasonic waves transmitted along the pipeline 2, it is convenient to filter the signals received by the ultrasonic wave receiver subsequently.

[0058] In this embodiment, the periphery of the upper strip-shaped groove 111 can be made of or provided with a damping material to prevent the ultrasonic waves emitted by the ultrasonic wave generator from being transmitted along the pipeline 2; the periphery of the upper strip-shaped groove 111 can be made of or provided with a damping material to prevent the ultrasonic waves transmitted along the pipeline 2 from being received by the ultrasonic wave receiver.

[0059] As Figure 7As shown, in an alternative embodiment, the ultrasonic mechanism includes an ultrasonic generator and an ultrasonic receiver electrically connected to the control module. The ultrasonic generator is disposed inside the upper strip-shaped groove 111, and the control module controls the ultrasonic generator to emit ultrasonic waves. The ultrasonic receiver is disposed inside the lower strip-shaped groove 121, and the control module controls the ultrasonic receiver to receive the ultrasonic waves emitted by the corresponding ultrasonic generator. The upper strip-shaped groove 111 restricts the area where the ultrasonic generator emits ultrasonic waves. The plane formed by the ultrasonic waves emitted by the two ultrasonic generators at the head position and the tail position is parallel to the vertical cross-section of the horizontally arranged pipeline 2. The plane formed by the ultrasonic waves emitted by the ultrasonic generator at the middle position is perpendicular to the vertical cross-section of the horizontally arranged pipeline 2, and the range corresponding to the ultrasonic waves emitted by the ultrasonic generator at the middle position contacts the range corresponding to the ultrasonic waves emitted by the ultrasonic generator at the head position.

[0060] In summary, the method for monitoring the water supply pipeline of a power converter station includes: arranging a detection device on the pipeline 2, and three ultrasonic mechanisms are sequentially arranged along the liquid flow direction in the pipeline 2 of the detection device, and the liquid first passes through the ultrasonic mechanism at the head position; the control module adjusts the power of the ultrasonic waves emitted by the remaining two ultrasonic mechanisms according to the detection result of the ultrasonic mechanism at the tail position, so that the liquid meets the required detection environment; after the liquid meets the detection environment, the control module controls the ultrasonic mechanism at the middle position to emit ultrasonic waves to detect the flow rate of the liquid, thereby realizing that when detecting the flow rate of the liquid in the pipeline 2 by ultrasonic waves, the bubbles in the liquid in the pipeline 2 are first eliminated, so that the ultrasonic detection of the flow rate can be more accurate.
