[0029] like Figure 1 As shown, the clamping structure of this embodiment includes: a mounting assembly 10, a first clamping member 20, a second clamping member 30 and a connecting member 40. The mounting assembly 10 is connected between the measuring member 100 and the structure to be measured, and part of the structure of the measuring member 100 is inserted into the mounting assembly 10. The first end of the first clamping member 20 is hingedly connected to the mounting assembly 10, and the first end of the second clamping member 30 is hingedly connected to the mounting assembly 10, and the first clamping member 20 and the second clamping member 30 clamp the structure to be measured. The connecting member 40 is detachably connected to the second end of the first clamping member 20 and the second end of the second clamping member 30.

[0030] The technical solution of this embodiment is applied, and the clamping structure includes a mounting assembly 10, a first clamping member 20, a second clamping member 30 and a connecting member 40. The mounting assembly 10 is connected between the measuring member 100 and the structure to be measured, and part of the structure of the measuring member 100 is arranged in the mounting assembly 10. The first end of the first clamping member 20 and the first end of the second clamping member 30 are both hingedly connected to the mounting assembly 10, and the first clamping member 20 and the second clamping member 30 clamp the structure to be measured together. The connecting member 40 is detachably connected to the second end of the first clamping member 20, and the connecting member 40 is detachably connected to the second end of the second clamping member 30. Through the above-mentioned arrangement, the first clamping member 20 and the second clamping member 30 can clamp the structure to be measured, and the first clamping member 20 and the second clamping member 30 are both connected to the mounting assembly 10, so that the relative position between the mounting assembly 10 and the structure to be measured is more stable, and then the relative position between the measuring member 100 and the structure to be measured can be more stable, that is, the connection strength between the measuring member 100 and the structure to be measured is better. The connecting member 40 is detachably arranged, so that it is convenient to connect the first clamping member 20 and the second clamping member 30, or to loosen the first clamping member 20 and the second clamping member 30. Since the first clamping member 20 and the second clamping member 30 are hingedly connected, when the clamping structure is separated from the measured structure, the first clamping member 20 and the second clamping member 30 can both swing from the inside of the measured structure to the outside of the measured structure, so that the clamping structure is convenient to separate from the measured structure. Therefore, the technical solution of this embodiment effectively solves the problem of low connection strength between the online detector and the transportation pipeline in the related art.

[0031] The measuring member 100 is a gas online monitor, and the measured structure is a pipeline. The measuring member 100 can monitor the gas in the pipeline in real time. Usually, a threaded connection joint is provided on the gas measuring member 100, and the connection joint can fix the measuring member 100 on the measured structure. Compared with plug-in connection, the screw connection method can reduce the risk of loosening and falling of the measuring member 100. However, for some use environments that are easily disturbed by the outside world, it is difficult to prevent the measuring member 100 from maintaining a stable connection with the measured structure when it is hit by external forces by simply relying on the screw connection method. Therefore, when the clamping structure of this embodiment is used, the first clamping member 20 and the second clamping member 30 can clamp the measured structure, and the first clamping member 20 and the second clamping member 30 are both connected to the mounting assembly 10, and the mounting assembly 10 is connected between the measuring member 100 and the measured structure, so that the measuring member 100 can be more stably connected to the measured structure, that is, the connection strength between the measuring member 100 and the measured structure is better. Part of the structure of the measuring piece 100 is disposed inside the mounting assembly 10 , namely, the connecting joint is disposed inside the mounting assembly 10 .

[0032] The connecting member 40 includes a screw and a nut. By adjusting the position of the nut on the screw, the clamping force of the first clamp 20 and the second clamp 30 on the measured structure can be adjusted or adapted to pipes of different sizes. The measured structure is a pipe.

[0033] like Figure 2 and Figure 4 As shown, in this embodiment, the mounting assembly 10 includes a pressure ring 11 and a mounting member 12, the pressure ring 11 is threadedly connected to the measuring member 100, the mounting member 12 is arranged between the pressure ring 11 and the measured structure, the first end of the first clamping member 20 and the first end of the second clamping member 30 are spaced and connected to the mounting member 12, and the pressure ring 11 can rotate relative to the measuring member 100 to clamp the mounting member 12 between the pressure ring 11 and the measured structure. The pressure ring 11 can rotate relative to the measuring member 100, and then when the pressure ring 11 moves toward the measured structure, the pressure ring 11 can press the mounting member, so that the relative position between the mounting member 12 and the measured structure is more stable, and the first clamping member 20 and the second clamping member 30 are both connected to the mounting member 12, so that the first clamping member 20 and the second clamping member 30 can stably clamp the measured structure, thereby making the connection between the measuring member 100 and the measured structure more stable.

[0034] The connecting joint is threadedly connected to the pressure ring 11 .

[0035] like Figure 2 and Figure 4 As shown, in this embodiment, the mounting member 12 includes a first mounting semi-ring member 121 and a second mounting semi-ring member 122, the first clamping member 20 is hingedly connected to the first mounting semi-ring member 121, the second clamping member 30 is hingedly connected to the second mounting semi-ring member 122, and the mounting assembly 10 further includes a limiting ring 13, which is arranged around the outer periphery of the first mounting semi-ring member 121 and the second mounting semi-ring member 122. The limiting ring 13 can limit the movement of the first mounting semi-ring member 121 in the radial direction of the limiting ring 13, and can also limit the movement of the second mounting semi-ring member 122 in the radial direction of the limiting ring 13, so as to avoid the movement of the first mounting semi-ring member 121 and the second mounting semi-ring member 122 in the radial direction of the limiting ring 13. The pressure ring 11 presses the first mounting half ring 121 and the second mounting half ring 122 between the pressure ring 11 and the measured structure, that is, the pressure ring 11 can limit the axial movement of the first mounting half ring 121 and the second mounting half ring 122 in the axial direction of the limiting ring 13. Therefore, under the joint action of the pressure ring 11 and the limiting ring 13, the connection between the first mounting half ring 121 and the second mounting half ring 122 and the measured structure is more stable.

[0036] The first mounting half ring 121 includes a first mounting half ring, and the second mounting half ring 122 includes a second mounting half ring. The first mounting half ring and the second mounting half ring are both provided with a fixing portion on one side facing the structure to be measured. The fixing portion is a semi-annular fixing ring, and the fixing rings provided on the first mounting half ring and the second mounting half ring are both located in the limiting ring 13.

[0037] like Figure 2 and Figure 4 As shown, in this embodiment, the mounting assembly 10 further includes a stop ring 14, which is disposed between the pressure ring 11 and the mounting member 12, and a stop convex portion 15 is disposed on the stop ring 14, and a stop concave portion 16 that stops and cooperates with the stop convex portion 15 is disposed on the mounting member 12. The pressure ring 11 can press the stop ring 14, and the stop convex portion 15 disposed on the stop ring 14 can cooperate with the stop concave portion 16 disposed on the mounting member 12, so as to prevent the mounting member 12 from rotating around the axis of the pressure ring 11, thereby making the position of the mounting member 12 more stable.

[0038] The stop convex part 15 includes a first stop column and a second stop column, and the stop concave part 16 includes a first groove for stop cooperation with the first stop column and a second groove for stop cooperation with the second stop column. The first groove is arranged on the first installation half ring 121, and the second groove is arranged on the second installation half ring 122.

[0039] Of course, in other embodiments, the mounting member 12 may be provided with a stopping protrusion 15 , and the stopping ring 14 may be provided with a stopping recess 16 that stops and cooperates with the stopping protrusion 15 .

[0040] like Figure 3 As shown, in this embodiment, the first clamping member 20 includes a first fixed plate 21 and an elastic clamping portion 22 arranged on the side of the first fixed plate 21 facing the structure to be measured, the first end of the first fixed plate 21 is hingedly connected to the first mounting half ring 121, and the elastic clamping portion 22 fits the structure to be measured. The first fixed plate 21 can clamp the structure to be measured. When the first fixed plate 21 moves toward the direction close to the structure to be measured, the elastic clamping portion 22 arranged between the first fixed plate 21 and the structure to be measured can be squeezed by the structure to be measured and deformed, so that the first fixed plate 21 can clamp the structure to be measured more stably.

[0041] like Figure 3As shown, in this embodiment, the elastic clamping portion 22 includes an elastic pad 221 and a second fixing plate 222 movably connected to the first fixing plate 21, and the elastic pad 221 is arranged between the second fixing plate 222 and the first fixing plate 21. The second fixing plate 222 can abut against the measured structure, and then the second fixing plate 222 can move toward the direction close to the first fixing plate 21, and squeeze the elastic pad 221 arranged between the first fixing plate 21 and the second fixing plate 222, so that the elastic pad 221 is deformed.

[0042] like Figure 3 As shown, the measuring device of this embodiment includes a measuring piece 100 and a clamping structure connected to the measuring piece 100, and the clamping structure is the above-mentioned clamping structure. When the above-mentioned clamping structure is in use, the first clamping piece 20 and the second clamping piece 30 can clamp the structure to be measured, and the first clamping piece 20 and the second clamping piece 30 are both connected to the mounting assembly 10, and the mounting assembly 10 is connected between the measuring piece 100 and the structure to be measured, so that the measuring piece 100 can be more stably connected to the structure to be measured, that is, the connection strength between the measuring piece 100 and the structure to be measured is better. The measuring device with the above-mentioned clamping structure also has the above-mentioned advantages.

[0043] like Figure 3 , Figure 5 as well as Figure 7 As shown, in this embodiment, the measuring member 100 includes a measuring body 101, a display structure 102, a controller and a flexible protective structure 103. The display structure 102, the controller and the flexible protective structure 103 are all arranged on the measuring body 101, and the flexible protective structure 103 is covered on the outside of the display structure 102. The controller can record the measurement data of the measuring body 101 and transmit the measurement data to the display structure 102, so that the display structure 102 displays the measurement data. The flexible protective structure 103 can protect the display structure 102 and reduce the probability of the display structure 102 being damaged.

[0044] like Figure 5 and Figure 6 As shown, in this embodiment, the flexible protection structure 103 includes a mounting plate 1031, a protection cover 1032, and an elastic member 1033 connected between the mounting plate 1031 and the protection cover 1032. The display structure 102 is arranged on the mounting plate 1031, and the protection cover 1032 is arranged on the outer periphery of the display structure 102. The mounting plate 1031 can support the display structure 102. The protection cover 1032 can protect the display structure 102. The elastic force of the elastic member 1033 can offset part of the impact force and protect the display structure 102. The elastic member 1033 can apply an elastic force to the protection cover 1032, so that the protection cover 1032 can move in a direction away from the mounting plate 1031 after being impacted.

[0045] At least the position of the protective cover 1032 facing the screen is set to be transparent. In this embodiment, the protective cover 1032 is composed of an annular main board and a transparent observation plate covering the central hole of the annular main board to reduce the difficulty of processing. In this embodiment, the elastic member 1033 is a spring.

[0046] like Figure 5 and Figure 6 As shown, in this embodiment, the flexible protection structure 103 further includes a panel 1034, which is disposed on a side of the protection cover 1032 facing the mounting plate 1031, and a movable gap is provided between the panel 1034 and the mounting plate 1031. The panel 1034 can limit the distance of movement of the protection cover 1032 toward the display structure 102, thereby preventing the protection cover 1032 from contacting the display structure 102, and further preventing the display structure 102 from being damaged due to the extrusion of the protection cover 1032.

[0047] Of course, in other embodiments, the enclosure 1034 is disposed on a side of the mounting plate 1031 facing the protective cover 1032 , and a movable gap is provided between the enclosure 1034 and the protective cover 1032 .

[0048] The measuring member 100 can provide real-time feedback on the gas flow in the pipeline. The connecting joint is arranged below the measuring body 101. The connecting joint and the measuring body 101 are detachably connected. The connecting joint can be inserted into the pipeline and screwed with the pipeline to achieve the connection between the measuring body 101 and the pipeline. At the same time, a sealing ring is also provided on the connecting joint to achieve a sealed connection between the connecting joint and the pipeline.

[0049] The second clamping member 30 has the same structure as the first clamping member 20. The first end of the first fixing plate 21 of the second clamping member 30 and the first end of the first fixing plate 21 of the first clamping member 20 are respectively detachably connected to the radial sides of the connecting joint through hinge seats. The first clamping member 20 and the second clamping member 30 can be enclosed to form a closed annular structure.

[0050] The first mounting half ring 121 and the second mounting half ring 122 are both provided with hinge seats. The first fixed plate 21 is an arc-shaped plate. A swing rod concentric with the first fixed plate 21 is connected to the first end of the first fixed plate 21, the swing rod is arc-shaped, and the swing rod is rotatably connected to the hinge seat. A connecting rod concentric with the first fixed plate 21 is provided at the second end of the first fixed plate 21, the connecting rod is arc-shaped, and a connecting block extending away from the center of the circle is provided at one end of the connecting rod away from the first fixed plate 21, and a connecting hole is provided on the connecting block, and a screw rod is passed through the screw rod and fixed by a nut.

[0051] The second fixing plate 222 is also an arc-shaped plate, which can be attached to the side wall of the pipeline. In order to adapt to pipelines of different sizes, the second fixing plate 222 can move toward or away from the center of the first fixing plate 21. Specifically, a guide hole is provided on the first fixing plate 21, and a connecting column is inserted into the guide hole. The length of the connecting column is greater than the thickness of the first fixing plate 21. One end of the connecting column is connected to the second fixing plate 222, and the other end of the connecting column is connected to the connecting plate located on the outside of the first fixing plate 21. At this time, in order to ensure the clamping force of the second fixing plate 222 on the pipeline, an elastic pad 221 is provided between the second fixing plate 222 and the first fixing plate 21. The elastic pad 221 has a deformation amount, which can make the second fixing plate 222 always maintain the tendency to move toward the center of the first fixing plate 21 and thereby tighten the pipeline.

[0052] In this embodiment, the elastic pad 221 is a buffer pad with elasticity, and two connecting posts are provided, the elastic pad is located between the two connecting posts and fixed on the second fixing plate 222. More specifically, the length of the guide hole along the circumferential direction of the first fixing plate 21 is less than the distance between the two connecting posts, and the length between the two ends of the elastic pad 221 is less than the distance between the two connecting posts, so that the connecting post can reciprocate in the guide hole, so that the position of the second fixing plate 222 on the first fixing plate 21 can be adjusted to provide a better fixing effect.

[0053] There are many ways to detachably connect the first clamping member 20 and the second clamping member 30 to the connecting joint. Based on the existing monitoring instrument structure, the connecting joint includes a small diameter section connected to the measuring body 101 and a large diameter section connected to the pipeline. The small diameter section and the large diameter section are perpendicular to each other to form a limiting step. The limiting ring 13 abuts against the limiting step.

[0054] After the connecting joint is screwed on the pipeline, the pressure ring 11 is screwed on to move the pressure ring 11 along the axial direction of the connecting joint away from the mounting part 12 to provide space for the mounting part 12 to move. Then, the first mounting half ring 121 and the second mounting half ring 122 are respectively placed on the limiting ring 13, and the fixing part is inserted into the limiting ring 13. The pressure ring 11 is screwed on in the reverse direction to fix the mounting part 12. Then, the first clamping part 20 and the second clamping part 30 are connected to complete the fixing effect of the first clamping part 20 and the second clamping part 30 on the pipeline, and the monitoring work is carried out normally.

[0055] When the measuring piece 100 needs to be removed from the pipeline, first disassemble the second end of the first clamping piece 20 and the second end of the second clamping piece 30, suspend and twist the pressure ring 11 to move the pressure ring 11 away from the mounting piece 12, move the first mounting half ring 121 and the second mounting half ring 122 away from the limiting ring 13 until the fixing part is separated from the limiting ring 13, and then remove the first mounting half ring 121 and the second mounting half ring 122 radially along the connecting joint.

[0056] An interface for connecting to external devices is provided on one side of the measuring body 101, and an alarm is provided on the other side. At the same time, a first mounting block is fixedly connected to the top of the measuring body 101, and a mounting hole is provided on the first mounting block, which can be connected to other external structures to further provide structural stability of the measuring piece. At the same time, second mounting blocks are provided on both sides of the bottom of the measuring body 101, and mounting holes are also provided on the second mounting blocks for connecting to other external structures.

[0057] When the insulating gas online monitoring device in this embodiment is connected to the pipeline, the connecting joint is first inserted into the pipeline and the first connection with the pipeline is achieved by hanging and screwing, and then the first clamp 20 and the second clamp 30 are clamped on the pipeline to achieve the second connection with the pipeline. The first clamp 20 and the second clamp 30 can increase the contact area between the pipeline and the measuring member 100, thereby improving the firmness of the connection between the pipeline and the measuring member 100. It should be emphasized that in order to avoid the first clamp 20 and the second clamp 30 hindering the hanging screwing between the connecting joint and the pipeline, the first clamp 20 and the second clamp 30 are detachably connected to the connecting joint. Before the connecting joint and the pipeline are screwed together, the measuring device in this embodiment should first remove the first clamp 20 and the second clamp 30 from the connecting joint, and then install the first clamp 20 and the second clamp 30 on the connecting joint after screwing, and connect the first clamp 20 and the second clamp 30 to achieve further connection with the pipeline.

[0058] The measuring device of this embodiment is an insulating gas online monitoring device. On the basis of connecting the measuring body 101 and the pipeline by screw connection, a clamping structure is also provided to increase the contact area between the measuring body 101 and the pipeline, thereby improving the stability of the connection between the measuring body 101 and the pipeline and reducing the possibility of gas leakage. It can be understood that the insulating gas online monitoring device can be used to monitor different insulating gases, and the monitor used can be replaced according to the different monitored gases during specific use. The gas online monitor of this embodiment is used to monitor sulfur hexafluoride.

[0059] The insulating gas online monitoring device of this embodiment adds a clamping structure to the monitor, which can cooperate with the connecting joint in the measuring body 101 that is screwed to the pipeline to achieve a stable connection with the pipeline, thereby reducing the possibility of leakage at the connection after collision with foreign objects; at the same time, the clamping structure and the gas online monitor are detachably connected, which can avoid interference between the clamping structure and the connecting joint when the pipeline is screwed.

[0060] In order to achieve a stable connection between the protective cover 1032 and the mounting plate 1031, the flexible protective structure 103 also includes a concentrically arranged annular fixing plate, a separating ring and a protective ring, wherein one axial end of the annular fixing plate is fixed at the center of the mounting plate 1031 and surrounds the display structure 102, one axial end of the separating ring is fixed at the center of one side of the protective cover 1032 facing the mounting plate 1031, and the other end is connected to the protective ring, the protective ring is slidably matched with the annular fixing plate, and the end of the elastic member 1033 away from the mounting plate 1031 is indirectly connected to the protective cover 1032 by directly connecting to the protective ring.

[0061] Specifically, the radius of the separation ring is greater than the radius of the annular fixing plate, and a contact ring is provided between the separation ring and the annular fixing plate, and the contact ring is fixedly connected to the separation ring by means including but not limited to screw connection and abuts against the outer wall of the annular fixing plate. When the protective cover 1032 is hit by an external force, the separation ring, the contact ring and the protective ring connected thereto will move toward the mounting plate 1031, and under the guidance of the protective ring, the protective cover 1032 moves smoothly relative to the mounting plate.

[0062] The side wall of the annular fixing plate is provided with an axially extending limiting hole, and the side wall of the protective ring is provided with a limiting block, and the limiting block is inserted into the limiting block to realize the sliding connection between the annular fixing plate and the protective ring. It can be understood that the positions of the limiting block and the limiting hole can also be interchanged, that is, the limiting block is provided on the annular fixing plate, and the limiting hole is provided on the protective ring.

[0063] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0064] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0065] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0066] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
