Description

Technical Field

[0001] The present disclosure relates to the technical field of building construction, and in particular to a flow velocity monitoring method and a related device for a vertical pipeline of a non-Newtonian fluid. Background Art

[0002] In the interior wall construction of modern buildings, latex paint is usually used in the final process of wall construction to achieve the coating, coloring and leveling of the wall, so that the wall has basic uniformity and visual beauty. This process is generally used from residential to special places, and is usually done by manual painting. However, in high-height indoor scenes such as substation rooms, the vertical height of the wall can usually reach 10 meters or more. Using manual painting operations is difficult to ensure uniformity and also poses safety risks.

[0003] With the development and application of construction robots, there is a trend that robots can be used to replace manual labor to complete wall painting operations in high-altitude scenes. The widely used non-contact spraying operation realizes wall construction by pressurizing latex paint and spraying it in an atomized form to the wall. However, as a non-Newtonian fluid, the flow characteristics of latex paint are affected by many factors, such as viscosity, temperature, shear rate, etc. In actual spraying operations, changes in the flow rate of latex paint in vertical pipes may cause uneven spraying and even pipe blockage, which may seriously affect construction efficiency and quality. Especially in high-altitude wall construction scenes, ensuring smooth and stable transportation of latex paint from the storage tank to the high-altitude spray gun through the pipe is a problem that needs to be solved urgently. Summary of the invention

[0031] It should be understood that various modifications may be made to the embodiments of the present application. Therefore, the above description should not be considered as limiting, but only as an example of an embodiment. Other modifications within the scope and spirit of the present disclosure will occur to those skilled in the art.

[0032] The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate embodiments of the present disclosure and, together with the general description of the present disclosure given above and the detailed description of the embodiments given below, serve to explain the principles of the present disclosure.

[0033] These and other characteristics of the present disclosure will become apparent from the following description of a preferred form of embodiment given as a non-limiting example, with reference to the accompanying drawings.

[0034] It should also be understood that, although the present disclosure has been described with reference to some specific examples, those skilled in the art will be able to realize many other equivalent forms of the present disclosure that have the features described in the claims and are therefore within the scope of protection defined thereby.

[0035] The above and other aspects, features and advantages of the present disclosure will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

[0036] Specific embodiments of the present disclosure are described hereinafter with reference to the accompanying drawings; however, it should be understood that the embodiments claimed are merely examples of the present disclosure, which may be implemented in a variety of ways. Well-known and / or repeated functions and structures are not described in detail to avoid obscuring the present disclosure with unnecessary or redundant details. Therefore, the specific structural and functional details claimed herein are not intended to be limiting, but merely serve as a basis and representative basis for the claims to teach those skilled in the art to use the present disclosure in a variety of ways with substantially any suitable detailed structure.

[0037] This specification may use the phrases "in one embodiment," "in another embodiment," "in a further embodiment," or "in other embodiments," all of which may refer to one or more of the same or different embodiments according to the present disclosure.

[0038] Combination Figure 1 As shown, the non-Newtonian fluid vertical pipeline 1 includes a fixed tube 11 and a movable tube 12 which are telescopically connected to each other. The movable tube 12 can telescopically move up and down relative to the fixed tube 11. In the following text, latex paint is used as an example for explanation. It can be understood that other non-Newtonian fluids can be transmitted through the non-Newtonian fluid vertical pipeline 1 and the flow rate monitoring method for the non-Newtonian fluid vertical pipeline 1 provided by the present invention can be applied; in addition, the position height described in this article refers to the height from a certain position on the fixed tube 11 or the movable tube 12 to the ground. Therefore, for the fixed tube 11 fixed relative to the ground, the first position height and the second position height are usually unchanged. For the movable tube 12 that can move up and down, the third position height will change with the movement of the movable tube 12. Combined with Figure 2As shown, the first aspect of the present invention provides a flow rate monitoring method for a vertical pipeline 1 of a non-Newtonian fluid, comprising:

[0039] S100, obtaining a first position height of the fixed pipe 11 and a first actual flow velocity at a corresponding position in the pipe, obtaining a second position height of the fixed pipe 11 and a second actual flow velocity at a corresponding position in the pipe, and obtaining a third position height of the movable pipe 12 and a third actual flow velocity at a corresponding position in the pipe;

[0040] S200, determining a theoretical flow velocity at a position in the pipe corresponding to the third position height based on the first position height, the first actual flow velocity, the second position height, the second actual flow velocity, and the third position height;

[0041] S300: Determine whether the non-Newtonian fluid vertical pipeline 1 is in an abnormal state based on the third actual flow rate and the theoretical flow rate.

[0042] Furthermore, combined with Figure 1 As shown, in this embodiment, a first flow velocity sensor 01 is arranged at one end of the fixed pipe 11 close to the ground (here the height from the ground is the first position height in this embodiment), a second flow velocity sensor 02 is arranged at one end of the fixed pipe 11 away from the ground (here the height from the ground is the second position height in this embodiment), and a third flow velocity sensor 03 is arranged at the outlet end of the movable pipe 12 (here the height from the ground is the third position height in this embodiment). In step S100, the flow velocity at the corresponding position in the pipe, i.e., the first actual flow velocity, the second actual flow velocity and the third actual flow velocity can be detected by the first flow velocity sensor 01, the second flow velocity sensor 02 and the third flow velocity sensor 03. The first position height, the second position height and the third position height can be obtained by pre-measurement, or a distance measuring sensor can be added to the first flow velocity sensor 01, the second flow velocity sensor 02 and the third flow velocity sensor 03 to obtain the corresponding data.

[0043] Further, in step S200, determining a third theoretical flow rate at a position in the pipe corresponding to the third position height based on the first position height, the first actual flow rate, the second position height, the second actual flow rate and the third position height includes:

[0044] S210, determining a flow behavior index of a non-Newtonian fluid based on the first position height, the first actual flow velocity, the second position height, and the second actual flow velocity;

[0045] S220, determining a first theoretical flow velocity at a position in the pipe corresponding to the third position height based on the first actual flow velocity, the first position height, the third position height, and the flow behavior index;

[0046] S230, determining a second theoretical flow velocity at a position in the pipe corresponding to the third position height based on the second actual flow velocity, the second position height, the third position height and the flow behavior index;

[0047] S240: Calculate an average value based on the first theoretical flow rate and the second theoretical flow rate to determine the theoretical flow rate.

[0048] For pipeline analysis using the power law model, the shear stress and shear rate of non-Newtonian fluids in the pipeline satisfy the following relationship:

[0049]

[0050] In the above formula, τ represents the shear stress of the non-Newtonian fluid; K is the viscosity coefficient of the non-Newtonian fluid; is the shear rate of non-Newtonian fluid; n is the flow behavior index;

[0051] For the non-Newtonian fluid vertical pipe 1, it is set vertically to the ground, so it can be deduced from the above formula:

[0052]

[0053] In the above formula, R is the radius of the transmission pipe, C is the proportional constant, and v is the flow velocity;

[0054] According to the above formula and the obtained first position height, first actual flow rate, second position height, and second actual flow rate, we can get:

[0055]

[0056] After simplification, we get:

[0057]

[0058] In the above formula, v1 is the first actual flow velocity, h1 is the first position height, v2 is the second actual flow velocity, h2 is the second position height, and n is the flow behavior index.

[0059] Preferably, the calculated flow behavior index is stored as a characteristic identifier, which can facilitate the subsequent use of the non-Newtonian fluid vertical pipeline 1. For example, the flow behavior index of latex paint can be stored and directly applied during the subsequent latex paint spraying operation without calculating the flow behavior index again.

[0060] Furthermore, in step S210, based on the first position height h1, the first actual flow velocity v1, the second position height h2 and the second actual flow velocity v2, determining the flow behavior index n of the non-Newtonian fluid includes:

[0061]

[0062] In step S220, based on the first actual flow velocity, the first position height, the third position height and the flow behavior index, determining a first theoretical flow velocity at a position in the pipe corresponding to the third position height includes:

[0063]

[0064] Wherein, v1 is the first actual flow velocity, h1 is the first position height, v ′ 3p is the first theoretical flow velocity, h3 is the third position height, and n is the flow behavior index.

[0065] In step S230, based on the second actual flow rate, the second position height, the third position height and the flow behavior index, determining the second theoretical flow rate at the position in the pipe corresponding to the third position height includes:

[0066]

[0067] Wherein, v2 is the second actual flow velocity, h2 is the second position height, v ′ 3 ′ p is the second theoretical flow velocity, h3 is the third position height, and n is the flow behavior index.

[0068] In step S240, calculating an average value based on the first theoretical flow rate and the second theoretical flow rate to determine the theoretical flow rate includes:

[0069]

[0070] Among them, v 3p is the theoretical flow rate, v ′ 3p is the first theoretical flow rate, v ′ 3 ′ p is the second theoretical flow rate.

[0071] By calculating the average value of the first theoretical flow rate and the second theoretical flow rate as the theoretical flow rate, accidental deviations of the theoretical flow rate can be reduced, thereby ensuring the accuracy of the theoretical flow rate calculation result.

[0072] In step S300, determining whether the non-Newtonian fluid vertical pipeline 1 is in an abnormal state based on the third actual flow rate and the theoretical flow rate includes:

[0073] When |v 3p -v3|≤Δv T When the non-Newtonian fluid vertical pipeline 1 is determined to be not in an abnormal state;

[0074] When |v 3p -v3|>Δv T When , it is determined that the non-Newtonian fluid vertical pipeline 1 is in an abnormal state;

[0075] Among them, v 3p is the theoretical flow rate, v3 is the third actual flow rate, Δv T is the first preset threshold.

[0076] The specific value of the first preset threshold can be set as needed, that is, when the gap between the third actual flow rate and the theoretical flow rate is too large, so that the gap is greater than the first preset threshold, it is considered that the non-Newtonian fluid vertical pipeline 1 is in an abnormal state at this time, and pipeline blockage may have occurred or is about to occur.

[0077] Preferably, when the non-Newtonian fluid vertical pipeline 1 is in an abnormal state, the abnormal state information is fed back to the user. The abnormal state information can be fed back in the form of sound or light (such as a buzzer, etc.) to warn and remind the on-site staff to avoid the abnormality of the non-Newtonian fluid vertical pipeline 1 affecting the quality and efficiency of the spraying construction.

[0078] Furthermore, combined with Figure 3 and Figure 4 As shown, it also includes:

[0079] S400, when the non-Newtonian fluid vertical pipeline 1 is in an abnormal state, obtaining the fourth pre-adjustment position height of the movable tube 12 at one end close to the ground at this time, and controlling the movable tube 12 to move downward;

[0080] S500. When the movable tube 12 descends until the non-Newtonian fluid vertical pipeline 1 is no longer in an abnormal state, the fourth adjusted position height of the movable tube 12 close to the ground at this time is obtained, and the abnormal height range of the non-Newtonian fluid vertical pipeline 1 is determined based on the fourth pre-adjustment position height and the fourth adjusted position height.

[0081] In step S400, the non-Newtonian fluid vertical pipeline 1 is in an abnormal state. At this time, the fourth pre-adjustment position height is obtained by a distance measuring sensor or direct measurement, and then the movable tube 12 is controlled to move downward.

[0082] In step S500, as the movable tube 12 descends, the non-Newtonian fluid vertical pipeline 1 begins to be in a non-abnormal state at a certain moment. At this time, the fourth adjusted position height is obtained by a distance measuring sensor or direct measurement. Figure 4 As shown, a height range ΔH from the fourth pre-adjustment position height to the fourth post-adjustment position height is an abnormal height range.

[0083] Through step S400 to step S500, the abnormal position of the pipeline can be located to ensure construction efficiency and quality, which is also beneficial to the subsequent improvement of pipeline design and optimization of construction robots.

[0084] The flow rate monitoring method in the present invention can monitor the flow rate of the non-Newtonian fluid in the non-Newtonian fluid vertical pipeline 1, and can determine in real time whether the non-Newtonian fluid vertical pipeline 1 is in an abnormal state through the third actual flow rate and the theoretical flow rate, thereby realizing real-time monitoring of pipeline abnormalities or blockages. During construction processes such as latex paint spraying, the fluidity and stability of the non-Newtonian fluid in the pipeline can be continuously guaranteed, which can prevent blockage problems and is conducive to ensuring the uniformity of spraying in large-height scenes, thereby ensuring high efficiency and high quality of construction.

[0085] The second aspect of the present invention provides a flow rate monitoring device, Figure 1 and Figure 5 As shown, including:

[0089] Preferably, it also includes a telescopic control module, which is used to control the downward movement of the movable tube 12 when the non-Newtonian fluid vertical pipeline 1 is in an abnormal state. When the non-Newtonian fluid vertical pipeline 1 is in an abnormal state, the fourth pre-adjustment position height is obtained through the data acquisition module (in addition to the first flow velocity sensor 01, the second flow velocity sensor 02 and the third flow velocity sensor 03, it also includes a distance sensor arranged at the end of the movable tube 12 close to the ground), and then the telescopic control module controls the downward movement of the movable tube 12; as the movable tube 12 descends, the non-Newtonian fluid vertical pipeline 1 begins to be in a non-abnormal state at a certain moment, and at this time the fourth adjusted position height is obtained through the data acquisition module, combined with Figure 4 As shown, a height range ΔH from the fourth pre-adjustment position height to the fourth post-adjustment position height is an abnormal height range.

[0090] The flow rate monitoring device in the present invention collects data such as flow rate and position height of the non-Newtonian fluid in the non-Newtonian fluid vertical pipeline 1 through a data acquisition module, calculates the theoretical flow rate through a data processing module, and determines whether the non-Newtonian fluid vertical pipeline 1 is in an abnormal state through an abnormal judgment module, thereby realizing real-time monitoring of pipeline abnormalities or blockages. During construction processes such as latex paint spraying, the fluidity and stability of the non-Newtonian fluid in the pipeline can be continuously guaranteed, which can prevent blockage problems and is conducive to ensuring the uniformity of spraying in large-height scenes, thereby ensuring high efficiency and high quality of construction.

During the construction process such as latex paint spraying, the smoothness and stability of the non-Newtonian fluid in the pipeline can be continuously guaranteed, which can prevent blockage problems and is conducive to ensuring the uniformity of spraying in large-height scenes, thereby ensuring high efficiency and high quality of construction.

[0096] A fourth aspect of the present invention provides an electronic device, which includes at least a memory and a processor, wherein the memory stores a computer program, and the processor implements the steps of the flow rate monitoring method in the above embodiment when executing the computer program on the memory.
