Description

Technical Field

[0001] The present application relates to the field of shipbuilding, and in particular to a pipeline detection device, a liquid level remote sensing device and a ship. Background Art

[0002] Existing large cruise ships usually use liquid level telemetry control systems to obtain the draft status of each cabin on the cruise ship in real time.

[0003] The liquid level telemetry control system generally adopts the form of an air-blowing liquid level gauge. During the specific installation, the electrical control system is integrated inside the control cabinet. The bottom of the control cabinet is connected to the liquid level of each compartment to be detected through multiple pipelines. When working, the gas as the gas source will be blown into the liquid level through the pipeline, and then the pressure information fed back from the liquid level will be fed back to the electrical control system through the pipeline. The electrical control system can reflect the height of the liquid level based on the feedback pressure information.

[0004] In this regard, after the installation of the liquid level telemetry control system, if multiple pipelines are connected to the wrong positions of multiple compartments, the liquid level detection results of multiple compartments will be confused. Then, if the pipeline leaks, it will directly affect the results of the liquid level detection. Therefore, after the installation of the telemetry control system, it is necessary not only to calibrate the position of each pipeline, but also to test the sealing of each pipeline.

[0005] However, the existing detection method is to first use an external air source to blow air into the pipelines in sequence, and then the staff in the current cabin determines whether the end of the current pipeline is emitting air. If the current pipeline can emit air, it means that the current pipeline is not connected to the wrong cabin. Then, soapy water is sprayed on the joints of each pipeline to check for leaks. However, during the leak detection process, there are not only a lot of pipelines on site, which requires repeating the above operations one by one, but also the control cabinet is far away from the cabin, and it is necessary to use a walkie-talkie to communicate and report to each other whether there is a leak. The operation is cumbersome and time-consuming. Summary of the invention

[0010] According to a second aspect of the present application, a liquid level telemetry device is provided. The liquid level telemetry device includes the pipeline detection device and the liquid level telemetry system as described above.

[0011] In any of the above technical solutions, further, the liquid level telemetry system further includes a distributor and a plurality of third hoses.

[0012] In any of the above technical solutions, further, the liquid level telemetry system further includes a distribution end block. The second end of each second hose is connected to the first distribution port of the distribution end block, and each pipeline to be detected is connected to the second distribution port of the distribution end block.

[0013] In any of the above technical solutions, further, the liquid level telemetry system further includes a fourth hose, and the second port of the pressure regulating valve is connected to the pressure regulating port of the distribution end block through the fourth hose.

[0014] In any of the above technical solutions, further, the liquid level telemetry system further includes a fifth hose, and the drain port of the pressure regulating valve is connected to the drain port of the distribution end block through the fifth hose.

[0015] According to a third aspect of the present application, a ship is provided, and the ship includes the liquid level telemetry device as described above.

[0016] In any of the above technical solutions, further, the plurality of piezoelectric conversion modules, the plurality of second hoses, the pressure regulating valve, the first hose, and the gas source are all integrated in a control cabinet. The liquid level telemetry system includes a plurality of control cabinets. The second ends of the second hoses in each control cabinet are connected to the corresponding pipelines to be detected, and each pipeline to be detected is inserted into the liquid level to be obtained in the corresponding cabin.

[0017] According to the pipeline detection device of the present application, the pipeline detection device is used to detect the pipelines of the liquid level telemetry system. The liquid level telemetry system includes a plurality of piezoelectric conversion modules, a plurality of second hoses, a plurality of pipelines to be detected, a pressure regulating valve, a first hose, and a gas source. The plurality of piezoelectric conversion modules correspond to the plurality of second hoses one by one, and the plurality of pipelines to be detected correspond to the plurality of second hoses one by one. The first port of each piezoelectric conversion module is connected to the first end of the corresponding second hose, the second end of the second hose is connected to the corresponding pipeline to be detected, each pipeline to be detected is inserted into the liquid level to be obtained, the second port of each piezoelectric conversion module is connected to the first end of the first hose, and the second end of the first hose is connected to the first port of the pressure regulating valve. The gas source can supply gas to the first hose.

[0018] During operation, the gas from the gas source will be blown into the liquid level through the corresponding pipeline to be detected by the second hose. Then, the pressure information feedback from the liquid level will be fed back to the piezoelectric conversion module through the pipeline to be detected by the second hose. After the piezoelectric conversion module converts the pressure signal into an electrical signal, the electrical control system will then reflect the height of the liquid level according to the electrical signal. It should be noted here that the specific electrical control and the liquid level detection process belong to the prior art and will not be described in detail here.

[0019] The pipeline detection device of the present application includes a tee joint and a pressure gauge. When detecting the pipeline to be detected, the first end of the first hose is disconnected from the plurality of piezoelectric conversion modules and connected to the first interface of the tee joint. The first end of one of the second hoses is disconnected and connected to the second interface of the tee joint. The pressure gauge is connected to the third interface of the tee joint.

[0020] Specifically, after the above-mentioned accessories of the liquid level telemetry control system are installed and the pipeline to be detected needs to be detected. First, disconnect the first end of the first hose from the multiple piezoelectric conversion modules (i.e., unplug the first hose from the piezoelectric conversion module), and connect it to the first interface of the three-way joint. Then, disconnect the first end of one of the second hoses (i.e., unplug the second hose from the piezoelectric conversion module), and connect it to the second interface of the three-way joint. Finally, connect the pressure gauge to the third interface of the three-way joint.

[0021] After the pipeline detection device is installed, supply gas to the first hose through the gas source. The gas in the first hose enters the pipeline to be detected through the three-way joint. If gas can come out from the other end of the pipeline to be detected, it means that the current pipeline is not connected to the wrong compartment. Then, the staff at the other end of the pipeline seals the other end of the pipeline. At this time, observe the reading of the pressure gauge. If the reading of the pressure gauge changes (the pressure value decreases), it means that there is a leakage in the pipeline.

[0022] In summary, when calibrating the pipeline, there is no need to ventilate through an external gas source (only need to borrow the gas source of the original equipment for ventilation), and when detecting the pipeline tightness, there is no need to spray soapy water on the joints of each pipeline to check for leaks (only need to observe the pressure gauge). Compared with the existing detection methods, pipelines without leakage points can be quickly excluded, thus saving the leak detection time of the operators and improving the tightness detection efficiency.

However, various changes, modifications, and equivalents of the methods, devices, and / or systems described herein will be apparent after understanding the disclosure of this application. For example, the order of operations described herein is merely illustrative and is not limited to the order set forth herein. Rather, changes that will be apparent after understanding the disclosure of this application can be made, except for operations that must occur in a specific order. In addition, descriptions of features known in the art may be omitted for the sake of clarity and conciseness.

[0029] The features described herein may be implemented in different forms and should not be construed as limited to the examples described herein. Rather, the examples described herein are provided only to illustrate some of the many possible ways of implementing the methods, devices, and / or systems described herein that will be apparent after understanding the disclosure of this application.

[0030] Throughout the specification, when an element (such as a layer, region, or substrate) is described as "on" another element, "connected to" another element, "coupled to" another element, "above" another element, or "covering" another element, it may be directly "on", "connected to", "coupled to", "above", or "covering" another element, or there may be one or more other elements intervening therebetween. In contrast, when an element is described as "directly on", "directly connected to", "directly coupled to", "directly above", or "directly covering" another element, there may be no other elements intervening therebetween.

[0031] As used herein, the term "and / or" includes any one of the listed related items and any combination of any two or more of them.

[0032] Although terms such as "first", "second", and "third" may be used herein to describe various components, elements, regions, layers, or sections, these components, elements, regions, layers, or sections are not limited by these terms. Rather, these terms are only used to distinguish one component, element, region, layer, or section from another. Thus, a first component, element, region, layer, or section referred to in the examples described herein may also be termed a second component, element, region, layer, or section without departing from the teachings of the examples.

Thus, the term "above" includes both the orientation of "above" and "below" depending on the spatial orientation of the device. The device may also be positioned in other ways (e.g., rotated 90 degrees or at other orientations), and the spatial relationship terms used herein will be interpreted accordingly.

[0036] The features of the examples described herein may be combined in various ways that will be apparent after understanding the disclosure of this application. In addition, although the examples described herein have a variety of configurations, other configurations are possible as will be apparent after understanding the disclosure of this application.

[0037] The first aspect of the present application provides a pipeline detection device, thus solving the problems of troublesome operation and time waste in the pipeline detection process of the existing liquid level telemetry control system.

[0038] Existing large cruise ships usually adopt a liquid level telemetry control system to obtain the draft status of each cabin on the cruise ship in real time.

[0039] The liquid level telemetry control system generally adopts the form of a pneumatic liquid level gauge. During specific installation, the electrical control system is integrated inside the control cabinet. The bottom of the control cabinet is connected to the liquid levels of each cabin to be detected through multiple pipelines. During operation, the gas serving as the gas source will be blown into the liquid level through the pipelines, and then the pressure information feedback from the liquid level will be fed back to the electrical control system through the pipelines. The electrical control system can reflect the height of the liquid level based on the feedback pressure information.

[0040] In this regard, after the installation of the liquid level telemetry control system, if the positions of multiple pipelines are misconnected with multiple cabins, it will lead to chaotic liquid level detection results for multiple cabins. Then, if the pipelines leak, it will directly affect the liquid level detection results. Therefore, after the installation of the telemetry control system, it is necessary not only to proofread the positions of each pipeline but also to detect the sealing performance of each pipeline.

[0041] However, the existing detection method is to blow air into the pipelines in sequence with an external gas source first, and then the staff in the current cabin judges whether the end of the current pipeline emits gas. If the current pipeline can emit gas, it means that the current pipeline is not misconnected to the wrong cabin. Then, soapy water is sprayed on the joints of each pipeline to check for leaks. However, during the leak check process, there are not only a large number of pipelines on-site that need to repeat the above operations one by one, but also the control cabinet is far from the cabin, and it is necessary to use a walkie-talkie to communicate and report to each other whether there is a leakage situation. The operation is troublesome and time-consuming.

[0042] In view of this, as Figure 1 and Figure 2 shown, according to the first aspect of the present application, a pipeline detection device is provided. The pipeline detection device is used to detect the pipelines of the liquid level telemetry system. Among them, the liquid level telemetry system includes a plurality of piezoelectric conversion modules 100, a plurality of second hoses 600, a plurality of pipelines to be detected 1100, a pressure regulating valve 200, a first hose 500, and a gas source 1000. The plurality of piezoelectric conversion modules 100 correspond to the plurality of second hoses 600 one by one, the plurality of pipelines to be detected 1100 correspond to the plurality of second hoses 600 one by one. The first port of each piezoelectric conversion module 100 is connected to the first end of the corresponding second hose 600, the second end of the second hose 600 is connected to the corresponding pipeline to be detected 1100, each pipeline to be detected 1100 is connected to the liquid level to be obtained, the second port of each piezoelectric conversion module 100 is connected to the first end of the first hose 500, the second end of the first hose 500 is connected to the first port of the pressure regulating valve 200, and the gas source 1000 can supply gas to the first hose 500.

[0043] During operation, the gas from the gas source 1000 will be blown into the liquid level through the second hose 600 from the corresponding pipeline 1100 to be detected. Then, the pressure information feedback from the liquid level will be fed back to the piezoelectric conversion module 100 through the pipeline 1100 to be detected by the second hose 600. After the piezoelectric conversion module 100 converts the pressure signal into an electrical signal, the electrical control system will then reflect the height of the liquid level according to the electrical signal. It should be noted here that the specific electrical control and the liquid level detection process belong to the prior art and will not be described in detail here.

[0044] The pipeline detection device of the present application includes a tee joint 1 and a pressure gauge 3. When detecting the pipeline 1100 to be detected, the first end of the first hose 500 is disconnected from a plurality of piezoelectric conversion modules 100 and connected to the first interface of the tee joint 1. The first end of one of the second hoses 600 is disconnected and connected to the second interface of the tee joint 1. The pressure gauge 3 is connected to the third interface of the tee joint 1.

[0045] Specifically, when the above-mentioned accessories of the liquid level telemetry control system are installed and it is necessary to detect the pipeline 1100 to be detected, first, disconnect the first end of the first hose 500 from a plurality of piezoelectric conversion modules 100 (that is, unplug the first hose 500 from the piezoelectric conversion module 100) and connect it to the first interface of the tee joint 1. Then, disconnect the first end of one of the second hoses 600 (that is, unplug the second hose 600 from the piezoelectric conversion module 100) and connect it to the second interface of the tee joint 1. Finally, connect the pressure gauge 3 to the third interface of the tee joint 1.

[0046] After the pipeline detection device is installed, supply gas to the first hose 500 through the gas source 1000. The gas in the first hose 500 enters the pipeline to be detected through the tee joint 1. If the other end of the pipeline to be detected can emit gas, it means that the current pipeline is not connected to the wrong compartment. Then, the staff at the other end of the pipeline seals the other end of the pipeline. At this time, observe the reading of the pressure gauge 3. If the reading of the pressure gauge 3 changes (the pressure value decreases), it means that there is a leakage in the pipeline.

[0047] In summary, when calibrating the pipeline, not only is it not necessary to ventilate through the external gas source 1000 (only need to borrow the gas source 1000 of the original equipment for ventilation), but also when detecting the pipeline tightness, it is not necessary to spray soapy water on the joints of each pipeline to check for leaks (only need to observe the pressure gauge 3). Compared with the existing detection methods, the pipelines without leakage points can be quickly excluded, thus saving the leak detection time of the operators and improving the tightness detection efficiency.

[0048] In the embodiment of the present application, further, as Figure 1As shown, the pipeline detection device may further include a two-way valve 2, a first additional hose 4, and a second additional hose 5. When detecting the pipeline 1100 to be detected, the first end of the first hose 500 is connected to the first interface of the two-way valve 2, the second interface of the two-way valve 2 is connected to the first interface of the three-way joint 1 through the first additional hose 4, and the pressure gauge 3 is connected to the third interface of the three-way joint 1 through the second additional hose 5. Among them, a hose connection joint (the hose connection joint may be an internal thread straight joint) may be used to connect between the second additional hose 5 and the pressure gauge 3.

[0049] Specifically, when it is necessary to detect the pipeline 1100 to be detected after the above-mentioned accessories of the liquid level telemetry control system are installed, first, disconnect the first end of the first hose 500 from the multiple piezoelectric conversion modules 100 (that is, unplug the first hose 500 from the piezoelectric conversion module 100), and connect it to the first interface of the two-way valve 2. The second interface of the two-way valve 2 is connected to the first interface of the three-way joint 1 through the first additional hose 4. After that, disconnect the first end of one of the second hoses 600 (that is, unplug the second hose 600 from the piezoelectric conversion module 100), and connect it to the second interface of the three-way joint 1. Finally, the pressure gauge 3 is connected to the third interface of the three-way joint 1 through the second additional hose 5 and the hose connection joint.

[0050] According to a second aspect of the present application, a liquid level telemetry device is provided. The liquid level telemetry device includes the pipeline detection device and the liquid level telemetry system as described above.

[0051] In an embodiment of the present application, as Figure 2 shown, the liquid level telemetry system may further include a distributor 300 and multiple third hoses 700. The multiple piezoelectric conversion modules 100 correspond to the multiple third hoses 700 one by one. The second port of each piezoelectric conversion module 100 is connected to the distribution port of the distributor 300 through the corresponding third hose 700, and the input port of the distributor 300 is connected to the first end of the first hose 500.

[0052] In addition, the liquid level telemetry system further includes a distribution end block 400. The second end of each second hose 600 is connected to the first distribution port of the distribution end block 400, and each pipeline 1100 to be detected is connected to the second distribution port of the distribution end block 400. Each pipeline 1100 to be detected is a rigid pipe. Here, the pipeline 1100 to be detected is connected to Figure 2 the port below the distribution end block 400 in Figure 2 and the pipeline 1100 to be detected is not shown.

[0053] In addition, as Figure 2 shown, the liquid level telemetry system further includes a fourth hose 800. The second port of the pressure regulating valve 200 is connected to the pressure regulating port of the distribution end block 400 through the fourth hose 800.

[0054] In addition, as Figure 2 shown, the liquid level telemetry system further includes a fifth hose 900, and the drainage port of the pressure regulating valve 200 is connected to the drainage port of the distribution end block 400 through the fifth hose 900.

[0055] In addition, as Figure 2 shown, the gas source 1000 can be an air compressor, and the air compressor can be connected to the first hose 500.

[0056] During operation, the gas provided by the air compressor is regulated by the pressure regulating valve 200, and then after passing through the first hose 500 and the distributor 300, it respectively provides working pressure for a plurality of piezoelectric conversion modules 100 through a plurality of third hoses 700.

[0057] The gas of the gas source 1000 is blown into the liquid level through the second hose 600 and the distribution end block 400 and via the corresponding pipeline to be detected 1100. Then, the pressure information fed back in the liquid level will be fed back to the piezoelectric conversion module 100 by the second hose 600 through the pipeline to be detected 1100. After the piezoelectric conversion module 100 converts the pressure signal into an electrical signal, the electrical control system will then reflect the height of the liquid level according to the electrical signal.

[0058] During detection, first, disconnect the first end of the first hose 500 from a plurality of piezoelectric conversion modules 100 (i.e., unplug the first hose 500 from the piezoelectric conversion module 100), and connect the first interface of the two-way valve 2. The second interface of the two-way valve 2 is connected to the first interface of the three-way joint 1 through the first additional hose 4. After that, disconnect the first end of one of the second hoses 600 (i.e., unplug the second hose 600 from the piezoelectric conversion module 100), and connect the second interface of the three-way joint 1. Finally, the pressure gauge 3 is connected to the third interface of the three-way joint 1 through the second additional hose 5 and the hose connection joint.

[0059] When the pipeline detection device is installed, the gas in the first hose 500 enters the pipeline to be detected through the two-way valve 2 and the three-way joint 1. If gas can come out from the other end of the pipeline to be detected, it means that the current pipeline is not connected to the wrong compartment. After that, the staff at the other end of the pipeline seals the other end of the pipeline. At this time, observe the reading of the pressure gauge 3. If the reading of the pressure gauge 3 changes (the pressure value decreases), it means that there is a leakage in this pipeline.

[0060] In summary, when calibrating the pipeline, it is not necessary to ventilate through an external gas source (only need to borrow the gas source of the original equipment for ventilation), and when detecting the pipeline tightness, it is not necessary to spray soapy water on the joints of each pipeline to check for leaks (only need to observe the pressure gauge 3). Compared with the existing detection methods, pipelines without leakage points can be quickly excluded, thus saving the leak detection time of the operators and improving the tightness detection efficiency.

[0061] According to a third aspect of the present application, a ship is provided, which includes the liquid level telemetry device as described above. Among them, multiple piezoelectric conversion modules 100, multiple second hoses 600, pressure regulating valves 200, first hoses 500, and gas sources 1000 are all integrated in the control cabinet. The liquid level telemetry system includes multiple control cabinets. The second ends of the second hoses 600 in each control cabinet are connected to the corresponding pipelines 1100 to be detected, and each pipeline 1100 to be detected is inserted into the liquid level to be obtained in the corresponding cabin.

[0062] As an example, a ship (large cruise ship) may include 6 vertical areas. Among them, the first vertical area includes 6 control cabinets, the second vertical area includes 7 control cabinets, the third vertical area includes 6 control cabinets, the fourth vertical area includes 3 control cabinets, the fifth vertical area includes 6 control cabinets, and the sixth vertical area includes 5 control cabinets, for a total of 33 control cabinets and 146 sensors.

[0063] For the detection work after the installation of the liquid level telemetry control system, the most time-consuming part in the whole process is the (debugging personnel checking the position / airtightness of each pipeline one by one) work. Since the SMART control cabinets are installed quite far from the cabins in each vertical area, it is necessary to use walkie-talkies to communicate / have someone monitor in the cabin, etc. All the through-hull fitting joint areas need to be checked one by one, etc. Therefore, it takes 2 hours to check the entire pipeline system of one cabin. After using the pipeline detection device of the present application, it only takes 10 minutes to complete the detection, which can greatly save manpower, material resources and financial resources. Moreover, after using the pipeline detection device, the staff hardly enter the cabin, reducing the safety risk. Generally, a large cruise ship can save 53,600 yuan in labor costs and can be debugged 9 days in advance.

[0064] Finally, it should be noted that the above embodiments are only specific implementation manners of the present application, used to illustrate the technical solutions of the present application, rather than limiting them. The protection scope of the present application is not limited thereto. Although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: any person skilled in the art within the technical scope disclosed by the present application can still modify the technical solutions recorded in the foregoing embodiments or can easily think of changes, or perform equivalent replacements for some of the technical features; and these modifications, changes or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
