[0002] The velocity distribution of fluids in pipes is generally very complex. It includes not only parabolic laminar flow distribution, but also intense lateral pulsations and turbulent flow lines. This results in a highly uneven temperature or velocity field in the pipe, which in turn causes disorder in the density and composition of the internal material. Especially for pipes with large inner diameters, simply setting up sampling and detection devices on the surface often cannot accurately represent the state of the material inside the pipe.

[0003] In view of this, the applicant proposes a new technical solution that uses multiple detectors connected in series and inserted into the pipeline to intercept and sample online, thereby achieving a highly efficient and convenient technical effect. Utility Model Content

It includes a mounting connector, a sleeve, a support body, detection resistors, and a PCB circuit board. The end of the mounting connector is connected to the support body. Multiple detection resistors are disposed within the support body and are electrically connected to the PCB circuit board. The PCB circuit board is disposed outside the support body and electrically connected to the mounting connector. A sleeve is fitted over the PCB circuit board, allowing the sample to pass through the sleeve and contact the detection resistors.

[0007] Furthermore, the installation connector includes a Type-C connector, a sealing ring, a connecting thread, and a welding plug.

The connecting thread is connected to the sealing ring, and the sealing ring is fixedly sleeved on the exterior of the Type-C connector.

[0008] Furthermore, the detection resistor sheet is composed of two bent sensitive resistor sheets, and the detection resistor sheet is suitable for loading an extraction column;

[0009] The sensitive resistor element is one of a sensitive resistor, a gas-sensitive resistor, a force-sensitive resistor, or a thermistor.

[0010] Furthermore, the PCB circuit board is connected in parallel with multiple of the detection resistors and is equipped with a digital-to-analog converter module. The digital-to-analog converter module is adapted to convert the analog signal emitted by the detection resistors into a digital signal and transmit the digital signal to the Type-C connector.

[0011] Furthermore, the support body includes a housing, a fixing hole, a contact point, and a detection groove. The housings are arranged in pairs and assembled and fixed through the fixing hole provided on one side of the housing.

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0028] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0029] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in sequences other than those illustrated or described herein.

[0030] Furthermore, the terms “including” and “having” and any variations thereof are intended to cover non-exclusive inclusion, such as a process, method, system, product, or apparatus that includes a series of steps or units, which is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or apparatus.

[0031] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., may be used here to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figure. It should be understood that spatial relative terms are intended to include different orientations in use or operation in addition to the orientation of the device as described in the figure.

[0032] For example, if a device in the accompanying drawings is inverted, a device described as "above" or "on top of" other devices or structures will subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below". The device may also be positioned differently, rotated 90 degrees, or in other orientations, and the spatial relative descriptions used herein will be interpreted accordingly.

[0033] Please refer to this as well. Figures 1-6 This utility model discloses an online interception and sampling device for online detection of laminar flow distribution and sampling within a pipeline. The main structure includes a mounting connector 1, a retaining sleeve 2, a support body 3, detection resistors 4, and a PCB circuit board 5. The mounting connector 1 is primarily used to fix the support body 3, and its end is connected to the support body 3. Multiple detection resistors 4 are disposed within the support body 3. Each detection resistor 4 is essentially a semiconductor that changes its resistance when sensing different environmental changes. These resistors 4 are electrically connected to the PCB circuit board 5, which is located outside the support body 3 and electrically connected to the mounting connector 1. When the mounting connector 1 is connected to a data cable, current flows through the detection resistors 4. When external fluid passes through the detection resistors 4, the resistance of the resistors changes, generating a related physical quantity, which is transmitted to the host computer via the data cable through the PCB circuit board 5, thus achieving online detection. Furthermore, since the PCB circuit board 5 is located outside the support body 3 and electrically connected to the mounting connector 1, and the retaining sleeve 2 is fitted over the PCB circuit board 5, it provides protection. Furthermore, since the sleeve 2 is provided with a sleeve hole, external fluid samples can pass through the sleeve 2 and contact the detection resistor 4, thus not affecting the detection function of the detection resistor 4.

[0034] In this embodiment, as Figure 3 The sleeve 2 is open at one end and has multiple through holes 6 on its side, with each through hole 6 corresponding to a number of detection slots 34. The sleeve 2 is made of titanium alloy, allowing it to fit over the paired housings 31 and placing the PCB circuit board 5 inside the sleeve 2, thus providing protection.

[0035] In some embodiments, such as Figure 5 The installation connector 1 includes a Type-C connector 11, a sealing ring 12, a connecting thread 13, and a welding plug 14. The Type-C connector 11 is connected to the welding plug 14 and is electrically connected. The connecting thread 13 is connected to the sealing ring 12. In this embodiment, the Type-C connector 11 can be connected to a mobile phone, allowing on-site detection of substances inside the pipeline via a mobile application installed on the phone. In actual use, a hole needs to be drilled in the pipeline using a tap. Since the welding plug 14 has a connecting thread 13 on its exterior, it can be directly threaded into the hole. Furthermore, to improve sealing, the sealing ring 12, which is fixedly fitted onto the outside of the Type-C connector 11, can further seal the hole, preventing pipeline leakage.

[0036] In this embodiment, the PCB circuit board 5 is connected in parallel with multiple sensing resistors 4 and a digital-to-analog converter module is installed. The digital-to-analog converter module is adapted to convert the analog signal emitted by the sensing resistors 4 into a digital signal and transmit the digital signal to the Type-C connector 11.

[0037] Optionally, in some embodiments, since the sensing resistor 4 consists of two bent sensitive resistor sheets, such as... Figure 6 Two curved sensitive resistor sheets form the inner wall of the test hole. Therefore, an extraction column can be inserted into the sensing resistor sheet 4, and sampling can be performed using the extraction column when the sensing resistor sheet 4 needs to be replaced. It should be noted that the sensitive resistor sheet mentioned in this embodiment is one of a sensitive resistor, gas-sensitive resistor, force-sensitive resistor, or thermistor, and various physical quantities can be detected through the sensitive resistor sheet.

[0038] In some embodiments, the support body 3 includes a housing 31, fixing holes 32, contacts 33, and a detection groove 34. The housings 31 are arranged in pairs and assembled and fixed through fixing holes 32 on one side of the housings 31. The housings 31 are made of stainless steel and filled with epoxy resin. The epoxy resin is used to bond and fix the detection resistor 4 in the detection groove 34. In this embodiment, the detection groove 34 is arranged linearly, which is beneficial for sampling and detecting different flow layers inside the pipe. Meanwhile, a PCB circuit board 5 is provided on the other side of the housing 31. The PCB circuit board 5 is electrically connected to the detection resistor 4 through the contacts 33. The detection resistor 4 is disposed in the detection groove 34, which is disposed between two adjacent fixing holes 32, thereby improving the installation stability of the PCB circuit board 5.

[0039] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
