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] Fire protection pipelines are arranged in converter stations. When it is necessary to detect the fire protection pipelines, real-time detection is required. However, due to the particularity of the fire protection pipelines, sensors cannot be installed by drilling holes or detection holes cannot be reserved at preset positions. And due to the particularity of converter stations, the non-contact form of electromagnetic detection will be affected and interfered by the converter. When ultrasonic detection is used, 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, the above description is not considered as 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:

[0007] A detection device is arranged 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.

[0008] 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.

[0009] 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.

[0010] 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:

[0011] 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 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 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.

[0012] In an alternative embodiment, the method for the control module to determine whether there are bubbles in the liquid includes:

[0013] 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 power of the received ultrasonic waves and the power of the emitted ultrasonic waves 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.

[0014] In an alternative embodiment, after it is determined that there are no bubbles, the control module controls the power of the ultrasonic waves 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 power of the ultrasonic waves 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 power of the ultrasonic waves 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;

[0015] The first preset power is greater than the second preset power.

[0016] 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 power of the ultrasonic waves 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, and 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 ratio of the power of the ultrasonic waves emitted by the ultrasonic mechanism at the middle position again;

[0017] 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;

[0018] 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 is in contact with the range corresponding to the ultrasonic waves emitted by the ultrasonic mechanism at the head position.

[0019] In a second aspect, an embodiment of the present disclosure further provides a monitoring system for the water supply pipeline of a power converter station, including:

[0020] An adjustment module configured 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, so that the liquid meets the required detection environment;

[0021] A flow rate module configured to detect the flow rate of the liquid by emitting ultrasonic waves through the ultrasonic mechanism at the middle position after the liquid meets the detection environment.

[0022] 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 method for monitoring the water supply pipeline of a power converter station are implemented.

[0023] 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 method for monitoring the water supply pipeline of a power converter station.

[0025] A moving mechanism sleeved on the pipeline, and three ultrasonic mechanisms are sequentially arranged on one side of the moving mechanism close to the pipeline along the flowing direction of the liquid in the pipeline, and the liquid first passes through the ultrasonic mechanism at the head position;

[0026] The ultrasonic mechanism is electrically connected to a control module, and the control module is configured to detect the flow rate of the liquid in the pipeline through the ultrasonic mechanism by using the above-mentioned method for monitoring the water supply pipeline of a power converter station.

[0027] In an optional implementation manner, the moving mechanism includes: an upper arc-shaped plate and a lower arc-shaped plate;

[0028] An accommodation area is formed between the upper arc-shaped plate and the lower arc-shaped plate to sleeve the upper arc-shaped plate and the lower arc-shaped plate on the pipeline;

[0029] The upper arc-shaped plate and the lower arc-shaped plate are directly connected by bolts;

[0030] On the side of the upper arc-shaped plate facing the pipeline, three upper strip-shaped grooves are provided along the liquid flow direction in the pipeline. The length directions of the first and last upper strip-shaped grooves are arranged along the circumferential direction of the inner wall of the upper arc-shaped plate, and the length direction of the upper strip-shaped groove at the middle line position is arranged along the length direction of the upper arc-shaped plate;

[0031] On the side of the lower arc-shaped plate facing the pipeline, lower strip-shaped grooves corresponding to the upper strip-shaped grooves are provided;

[0032] There are intervals between both ends of the upper arc-shaped plate and the lower arc-shaped plate in the circumferential direction and the outer wall of the pipeline, and shock-absorbing materials are filled in the intervals.

[0033] In an optional embodiment, the ultrasonic mechanism includes: an ultrasonic generator and an ultrasonic receiver electrically connected to the control module;

[0034] The ultrasonic generator is arranged inside the upper strip-shaped groove, and the control module controls the ultrasonic generator to emit ultrasonic waves;

[0035] The ultrasonic receiver is arranged 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.

[0036] The area where the ultrasonic generator emits ultrasonic waves is restricted by the upper strip-shaped groove;

[0037] The planes formed by the ultrasonic waves emitted by the two ultrasonic generators at the head position and the tail position are parallel to the vertical cross-section of the horizontally arranged pipeline;

[0038] 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 contacts the range corresponding to the ultrasonic waves emitted by the ultrasonic generator at the head position.

[0055] When a fire protection pipeline is arranged in a converter station and needs to be detected in real time during the detection of the fire protection pipeline, due to the particularity of the fire protection pipeline, in order to ensure the strength of the fire protection pipeline, 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 inventors found that when detecting the liquid flow velocity in the pipeline by ultrasonic waves, the ultrasonic waves will be affected by the bubbles in the liquid, resulting in inaccurate detected flow velocity.

[0056] All the defects existing in the above solutions are the results obtained by the inventors after practice and careful research. Therefore, the process of discovering the above problems and the solutions proposed in the present disclosure by the present disclosure for the above problems should be the contributions made by the inventors during the process of the present disclosure.

[0057] It should be noted that similar reference numerals and letters denote 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.

[0058] The following will describe in detail some embodiments of the present invention with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0059] As Figure 1As 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, in which three ultrasonic mechanisms are sequentially arranged 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, 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 achieving the elimination of bubbles in the liquid in pipeline 2 first when detecting the liquid flow rate in pipeline 2 by ultrasonic waves, so that the ultrasonic wave detection of the flow rate can be more accurate.

[0060] In this embodiment, the control module can adjust the power of the ultrasonic mechanism.

[0061] In this embodiment, since the ultrasonic waves will be affected by the bubbles in the liquid in the pipeline when using ultrasonic 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 defoam.

[0062] In this embodiment, the flow direction of the liquid is as Figure 6 shown F in

[0063] 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 pipeline 2; the ultrasonic mechanism at the middle position can emit ultrasonic waves to detect the flow rate of the liquid in pipeline 2; the ultrasonic mechanism at the tail position can emit ultrasonic waves to detect the defoaming effect of the bubbles in the liquid in pipeline 2.

[0064] In this embodiment, the liquid in 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 mechanisms are located outside pipeline 2.

[0065] 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 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 this first threshold, it is judged that there are still bubbles in the liquid.

[0066] In an alternative embodiment, the method for the control module to adjust the ultrasonic power 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 determines that there are bubbles in the liquid, first control the ultrasonic mechanism at the head position to emit ultrasonic waves. If it is still determined 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 ultrasonic power emitted by the ultrasonic mechanism at the head position reaches the preset maximum value. At this time, the ultrasonic power emitted by the ultrasonic mechanism at the head position is no longer increased.

[0067] 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 determine whether the bubbles are eliminated. If not, the ultrasonic power emitted by the ultrasonic mechanism at the head position is increased by a first preset power, and then it is determined again whether the bubbles are eliminated, and so on, until it is determined that there are no bubbles or the ultrasonic power emitted by the ultrasonic mechanism at the head position reaches the preset maximum value.

[0068] 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.

[0069] 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, in combination with the relationship between the transmission power and the distance.

[0070] 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 ultrasonic power by a second preset power, and then determines whether there are bubbles. If there are no bubbles, continue to reduce the 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 ultrasonic power emitted by the ultrasonic mechanism at the head position is the ultrasonic power corresponding to the ultrasonic wave 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, making the liquid 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.

[0071] In this embodiment, since ultrasonic waves are mechanical energy, it is necessary to minimize this mechanical energy as much as possible to avoid the impact of ultrasonic waves on other sensors, etc. Therefore, after determining that there are no bubbles, it is necessary to minimize the power corresponding to the ultrasonic waves emitted by the ultrasonic mechanism at the head position. That is, when it is determined that there are no bubbles and the power corresponding to the ultrasonic waves 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 decrease the second preset power each time on the basis of the current power, so that the power of the ultrasonic waves emitted by the ultrasonic mechanism at the head position gradually decreases. After each decrease, it is judged whether there are bubbles until it is first determined that there are bubbles, indicating that the power of the ultrasonic waves emitted by the ultrasonic mechanism at the head position at this time cannot meet the requirement of eliminating bubbles, and the power of the ultrasonic waves 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 keeps the power of the ultrasonic waves emitted by the ultrasonic mechanism at the head position at the power of the ultrasonic waves 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.

[0072] In this embodiment, the first preset power is greater than the second preset power, so that the change amount is smaller when reducing the power of the ultrasonic waves emitted by the ultrasonic mechanism at the head position, and the best condition of the power of the ultrasonic waves emitted by the ultrasonic mechanism at the head position can be found more accurately.

[0073] In this embodiment, since 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, the ultrasonic power 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 impact of the suddenly increased bubbles on the flow rate detection.

[0074] In an alternative embodiment, when the power of the ultrasonic wave 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 power of the ultrasonic wave 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. At this time, the power of the ultrasonic wave emitted by the ultrasonic mechanism at the head position and the ultrasonic mechanism at the middle position is maintained, so that there are no bubbles in the liquid, making the liquid meet the required detection environment, and the liquid flow rate is detected after the ultrasonic wave emitted by the ultrasonic mechanism at the middle position is increased by a preset proportion of power 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 2; the plane formed by the ultrasonic wave emitted by the ultrasonic 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 mechanism at the middle position is in contact with the range corresponding to the ultrasonic wave emitted by the ultrasonic mechanism at the head position.

[0075] In this embodiment, when the power of the ultrasonic wave emitted by the ultrasonic mechanism at the head position reaches the preset maximum value, but it is still determined that there are bubbles, it means that the ultrasonic mechanism at the head position cannot eliminate the bubbles. At this time, the ultrasonic mechanism at the middle position needs to assist. Since the range corresponding to the ultrasonic wave emitted by the ultrasonic mechanism at the middle position is in contact with the range corresponding to the ultrasonic wave emitted by the ultrasonic mechanism at the head position, the ultrasonic power will be superimposed at the contact position of the two, increasing the bubble elimination effect.

[0076] As Figure 3 and Figure 6 shown, in this embodiment, the plane formed by the ultrasonic waves emitted by the two ultrasonic mechanisms at the head position and the tail position is as Figure 3 in a the area shown. The plane formed by the ultrasonic wave emitted by the ultrasonic mechanism at the middle position is as Figure 6 in b the area shown.

[0077] In this embodiment, the power of the ultrasonic wave emitted by the ultrasonic mechanism at the middle position is continuously increased until it is determined that there are no bubbles, indicating that the power of the ultrasonic wave emitted by the ultrasonic mechanism at the middle position and the power of the ultrasonic wave emitted by the ultrasonic mechanism at the head position can eliminate the bubbles in the liquid. At this time, the power of both is maintained, and the power of the ultrasonic wave emitted by the ultrasonic mechanism at the middle position is increased by a preset proportion, such as 10%, to detect the liquid flow rate while ensuring the bubble elimination effect and ensuring the accurate detection of the liquid flow rate.

[0078] 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 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.

[0079] In this embodiment, the above modules may be virtual modules, and their functional steps may be integrated in the control module.

[0080] 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.

[0081] At least one other disclosed embodiment also 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.

[0082] As Figure 2 、 Figure 6 shown, at least one other disclosed embodiment also provides a detection device for the monitoring system of the water supply pipeline of a power converter station, including: a moving mechanism 1 sleeved on a pipeline 2, and three ultrasonic mechanisms are sequentially arranged on one side of the moving mechanism 1 close to the pipeline 2 along the liquid flow direction in the pipeline 2, and the liquid first passes through the ultrasonic mechanism at the head position; the ultrasonic mechanisms are electrically connected to a control module, and the control module is configured to detect the liquid flow rate in the pipeline 2 through the ultrasonic mechanisms by using the above-mentioned monitoring method for the water supply pipeline of the power converter station.

[0083] As Figure 4 and Figure 5 shown, in an optional implementation manner, the moving mechanism 1 includes: an upper arc plate 11 and a lower arc plate 12; an accommodating area is formed between the upper arc plate 11 and the lower arc plate 12 to sleeved the upper arc plate 11 and the lower arc plate 12 on the pipeline 2; the upper arc plate 11 and the lower arc plate 12 are directly connected by bolts 14; three upper strip-shaped grooves 111 are opened on the side of the upper arc plate 11 facing the pipeline 2 along the liquid flow direction 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 plate 11, and the length direction of the middle position upper strip-shaped groove 111 is arranged along the length direction of the upper arc plate 11; lower strip-shaped grooves 121 corresponding to the upper strip-shaped grooves 111 are opened on the side of the lower arc plate 12 facing the pipeline 2; there are intervals 13 between both ends of the upper arc plate 11 and the lower arc plate 12 and the outer wall of the pipeline 2 in the circumferential direction, and damping materials are filled in the intervals 13.

[0084] 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.

[0085] In this embodiment, since there are gaps 13 between both ends of the upper arc-shaped plate 11 and the lower arc-shaped plate 12 and the outer wall of the pipeline 2 in the circumferential direction, the upper arc-shaped plate 11 and the lower arc-shaped plate 12 can be adapted to pipelines 2 with different diameters, increasing the applicable scenarios of the detection device.

[0086] In this embodiment, the damping material can be silicone or the like, 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.

[0087] In this embodiment, the area around 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 area around 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.

[0088] As Figure 7 shown, in an alternative embodiment, the ultrasonic mechanism includes: an ultrasonic wave generator and an ultrasonic wave receiver electrically connected to the control module; the ultrasonic wave generator is arranged inside the upper strip-shaped groove 111, and the control module controls the ultrasonic wave generator to emit ultrasonic waves; the ultrasonic wave receiver is arranged inside the lower strip-shaped groove 121, and the control module controls the ultrasonic wave receiver to receive the ultrasonic waves emitted by the corresponding ultrasonic wave generator. The area where the ultrasonic wave generator emits ultrasonic waves is restricted by the upper strip-shaped groove 111; the plane formed by the ultrasonic waves emitted by the two ultrasonic wave 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 wave 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 wave generator at the middle position contacts the range corresponding to the ultrasonic waves emitted by the ultrasonic wave generator at the head position.

[0089] In summary, the monitoring method for the water supply pipeline of a power converter station includes: setting a detection device on pipeline 2, where three ultrasonic mechanisms are sequentially arranged in the detection device along the flowing direction of the liquid 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, 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. Thus, when detecting the flow rate of the liquid in pipeline 2 by ultrasonic waves, the bubbles in the liquid in pipeline 2 are first eliminated, making the ultrasonic flow rate detection more accurate.

[0091] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation to the present invention. In addition, terms such as "first", "second" and other numerical terms used in this article do not imply an order or sequence unless clearly indicated in this article. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer or section discussed above can be referred to as the second element, component, region, layer or section.

[0092] Spatially relative terms, such as "inner", "outer", "below", "beneath", "under", "above", "upper", etc., may be used herein to facilitate the description of the relationship between one element or feature and another element or feature as illustrated in the figures. In addition to the orientation depicted in the figures, spatially relative terms are intended to encompass different orientations of the device in use or operation. For example, if the device in the figures is flipped, an element described as "below" or "beneath" another element or feature will be oriented "above" the other element or feature. Thus, the exemplary term "below" can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are to be interpreted accordingly.

[0093] Inspired by the above-described ideal embodiments of the present invention, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of the present invention. The technical scope of the present invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
