Technical Field

[0001] The invention relates to the technical field of sensor installation, and in particular to a pressurized pipeline opening sensor installation device. Background Art

[0002] A sensor is a device that can sense certain physical, chemical or biological properties in the environment and convert them into electrical signals or other forms of information output. It is an indispensable part of modern scientific and technological systems and is widely used in industry, medical care, smart home, transportation, agriculture and other fields.

[0003] For example, sensors are installed in pipelines to monitor the operating status of pipelines. Such sensors can obtain information such as temperature, pressure, flow, composition, vibration, etc. in the pipelines. They are an indispensable monitoring method in industries such as industry, environmental protection, water treatment, and oil and gas.

[0004] When repairing, inspecting or installing branch pipelines on pipelines, various sensors need to be installed on the pipelines under pressure while ensuring the normal operation of the pipelines.

[0005] However, in the above scheme, a saddle-shaped piece will be formed due to the cutting during use. The elastic deformation of the saddle piece can easily get stuck in the drilling device, and after the cutting is completed, the saddle piece will enter the interior of the pipeline, affecting the use of the pipeline.

[0042] Refer to the following Figure 1-Figure 9 The following describes a pressurized pipeline opening sensor installation device provided by the present invention.

[0043] A pressurized pipeline hole drilling sensor installation device is suitable for installing a sensor after drilling a hole on the pressurized pipeline 400, comprising a sealed tube body 100, one end of the sealed tube body 100 is vertically connected to the side wall of the pressurized pipeline 400, a pipeline punching component or a sensor installation component can be installed in the sealed tube body 100, before installing the sensor, the pipeline punching component needs to be installed in the sealed tube body 100, and a hole is punched on the side wall of the pressurized pipeline 400 by using the pipeline punching component, and after the punching is completed, the pipeline punching component is taken out from the sealed tube body 100, and the sealing state of the sealed tube body 100 needs to be ensured when taking it out, and then the sensor installation component is installed in the sealed tube body 100, and the sensor is installed in the pressurized pipeline 400 by using the sensor installation component. The sensors include flow sensors, pressure sensors, liquid level sensors, etc., and suitable sensors are installed according to needs. However, when the pipe drilling assembly in the prior art is drilling a hole, since the side wall of the pressurized pipe 400 is cylindrical, when the drill bit of the drilling assembly is in vertical contact with the pressurized pipe 400, a part of the drill bit abuts against the side wall of the pressurized pipe 400, and the other part is suspended. As the drill bit rotates, the drill bit first drills through the abutting part, and the other part is gradually drilled through. A saddle piece similar to a saddle shape is formed after the drill bit drills. When the drill bit is about to drill through the side wall of the pressurized pipe 400, half of the saddle piece is separated from the side wall of the pressurized pipe 400. The elastic deformation of the saddle piece will clamp the drill bit, thereby causing the tool to get stuck, reducing the drilling efficiency, and even causing drilling failure in severe cases.

[0044] The present invention adjusts the angle between the hollow drill bit 170 and the pressurized pipe 400, that is, the hollow drill bit 170 is deflected in the circumferential direction of the pressurized pipe 400. Figure 3-Figure 5As shown, the pipeline drilling assembly of the present invention includes a hollow drill bit 170 and an adjusting ball plate 150, the adjusting ball plate 150 is located in the sealed tube body 100, the adjusting ball plate 150 can rotate around the axis of the sealed tube body 100 in the sealed tube body 100, and the connecting shaft 171 of the hollow drill bit 170 is connected to the adjusting ball plate 150, the connecting shaft 171 of the hollow drill bit 170 can be elastically retracted, the retractable part of the connecting shaft 171 of the hollow drill bit 170 adopts a keyway fit and can only retract and cannot rotate relatively, the connecting shaft 171 of the hollow drill bit 170 pushes the hollow drill bit 170 to always abut against the pressurized pipe 400, and the connection position of the connecting shaft 171 of the hollow drill bit 170 and the adjusting ball plate 150 can be along the pressurized pipe The circumferential sliding of the pipe 400 causes the hollow drill bit 170 to deflect, and the hollow drill bit 170 abuts against the pressurized pipe 400 at one end of the pressurized pipe 400 in the circumferential direction, and the hollow drill bit 170 can rotate around its own axis to drill the pressurized pipe 400, and the adjusting ball plate 150 drives the circumferentially deflected hollow drill bit 170 to revolve, and the hollow drill bit 170 simultaneously rotates, so that the hollow drill bit 170 can cut the saddle plate drilled on the side wall of the pressurized pipe 400 more evenly, instead of cutting one part and leaving the other part connected to the side wall of the pressurized pipe 400, thereby avoiding the above-mentioned tool jamming phenomenon, and allowing the hollow drill bit 170 to drill through the saddle plate all around at the same time, thereby improving the quality of drilling the pressurized pipe 400.

[0045] In a further embodiment, a sensing component is provided on the adjusting ball plate 150 of the present invention, and the sensing component can sense the diameter of the pressurized pipe 400, so that the deflection angle of the hollow drill bit 170 is adjusted according to the diameter of the pressurized pipe 400. If the diameter of the pressurized pipe 400 is larger, the curvature of the side wall of the pressurized pipe 400 is smaller, and the hollow drill bit 170 only needs to be deflected a little; if the diameter of the pressurized pipe 400 is smaller, the curvature of the side wall of the pressurized pipe 400 is larger, and the hollow drill bit 170 needs to be deflected at a larger angle to make the hollow drill bit 170 abut against the pressurized pipe 400 at one end of the pressurized pipe 400 in the circumferential direction. By setting the sensing component, the deflection angle of the hollow drill bit 170 can be adjusted to adapt to pressurized pipes 400 of different diameters, thereby expanding the scope of application.

[0046] Specifically, the sensing assembly includes two sensing telescopic rods 190, and the two sensing telescopic rods 190 are respectively located at the two ends of the adjusting ball plate 150 in the circumferential direction of the pressurized pipeline 400, as shown in FIG. Figure 6As shown, the ball plate 150 is adjusted to gradually move toward the pressurized pipe 400. Before the hollow drill bit 170 contacts the pressurized pipe 400, the two inductive telescopic rods 190 first abut against the pressurized pipe 400. The two inductive telescopic rods 190 gradually shorten. When the hollow drill bit 170 abuts against the pressurized pipe 400, the two inductive telescopic rods 190 stop shortening. The diameter of the pressurized pipe 400 is determined specifically by the shortened length of the inductive telescopic rods 190. When the sensing telescopic rod 190 is shortened to a longer length, it indicates that the curvature of the pressurized pipeline 400 is larger, that is, the diameter of the pressurized pipeline 400 is smaller, so the sensing telescopic rod 190 sends a signal to adjust the hollow drill bit 170 to a larger deflection angle; when the sensing telescopic rod 190 is shortened to a shorter length, it indicates that the curvature of the pressurized pipeline 400 is smaller, that is, the diameter of the pressurized pipeline 400 is larger, so the sensing telescopic rod 190 sends a signal to adjust the hollow drill bit 170 to a smaller deflection angle, and after the deflection angle is adjusted, the hollow drill bit 170 starts drilling.

[0047] More specifically, in order to realize the function of deflection of the hollow drill bit 170, a spherical rack 160 is slidably arranged on the adjusting ball plate 150, and a slide rail 151 is arranged on the adjusting ball plate 150, such as Figure 6 As shown, the slide rail 151 extends along the circumference of the pressurized pipe 400, and a slide groove (not shown in the figure) is provided on the surface where the spherical rack 160 contacts the adjusting ball plate 150. The slide groove also extends along the circumference of the pressurized pipe 400. The slide rail 151 is located in the slide groove, so that the spherical rack 160 can slide along the circumference of the pressurized pipe 400. The adjusting ball plate 150 is provided with a through groove 154, which is arranged parallel to the slide groove and passes through the center of the adjusting ball plate 150. The through groove 154 allows the connecting shaft 171 of the hollow drill bit 170 to pass through, and the connecting shaft 171 of the hollow drill bit 170 slides in the through groove 154 to deflect the hollow drill bit 170. A rotating gear 153 is also provided on the adjusting ball plate 150, and the rotating gear 153 is meshed with the spherical rack 160. A motor 152 is provided on the adjusting ball plate 150, and the motor 152 drives the rotating gear 153 to rotate. When the rotating gear 153 rotates, it can drive the spherical rack 160 to slide along the slide rail 151, and the spherical rack 160 drives the connecting shaft 171 of the hollow drill bit 170 to slide in the through groove 154 to change the angle of the hollow drill bit 170.

[0048] To facilitate the rotation of the adjusting ball plate 150, a driving shaft 140 is fixedly arranged on the adjusting ball plate 150. The driving shaft 140 is used to drive the adjusting ball plate 150 to rotate around the axis of the sealing tube body 100. The driving shaft 140 has an upper and lower part. The lower part is fixedly arranged on the adjusting ball plate 150. To avoid interference between the driving shaft 140 and the spherical rack 160, the lower part of the driving shaft 140 is eccentrically arranged on the adjusting ball plate 150, and the upper part of the driving shaft 140 coincides with the axis of the sealing tube body 100. When the driving shaft 140 rotates, it can drive the adjusting ball plate 150 to rotate around the axis of the sealing tube body 100.

[0049] More specifically, the upper end of the sealing tube body 100 is spirally connected with a first sealing plate 120, and the first sealing plate 120 can seal the upper end of the sealing tube body 100. A thread is arranged on the outer periphery of the first sealing plate 120, and a thread groove is arranged on the inner peripheral wall of the upper end of the sealing plate. The first sealing plate 120 is connected with the sealing plate through the thread and the thread groove. The first sealing plate 120 is connected to the upper part of the driving shaft 140, and the upper part of the driving shaft 140 can be telescopic. The side wall of the telescopic part of the driving shaft 140 is provided with an axially extending key and a key groove. The telescopic part of the driving shaft 140 can only be telescopic and cannot rotate relatively. The first sealing plate 120 is provided with a first driving motor 130. The first driving motor The rotating shaft 130 is meshed with the driving shaft 140, and the first driving motor 130 can drive the driving shaft 140 to rotate, thereby driving the adjusting ball plate 150 to rotate around the axis of the sealing tube body 100, and the adjusting ball plate 150 drives the deflected hollow drill bit 170 to revolve. When the first sealing plate 120 is installed on the sealing tube body 100, the telescopic part of the driving shaft 140 is in a shortened state. When drilling is required, the telescopic part of the driving shaft 140 is extended to make the adjusting ball plate 150 gradually move closer to the pressurized pipeline 400, so that the induction telescopic rod 190 on the adjusting ball plate 150 first contacts the pressurized pipeline 400, and then the hollow drill bit 170 contacts the pressurized pipeline 400.

[0050] A second drive motor 180 is fixedly arranged on the spherical rack 160. The rotating shaft of the second drive motor 180 is meshed with the connecting shaft 171 of the hollow drill bit 170. The second drive motor 180 drives the hollow drill bit 170 to rotate. The hollow drill bit 170 rotates to start drilling the pressurized pipe 400. After the side wall of the pressurized pipe 400 is subjected to the rotation and revolution of the hollow drill bit 170, the saddle piece formed can be drilled evenly around to avoid the tool jamming phenomenon.

[0051] In a further embodiment, the sensor mounting assembly includes a second sealing plate 200 and a mounting rod 210. The second sealing plate 200 can also be spirally connected to the upper end of the sealing tube body 100. The structure of the second sealing plate 200 is similar to that of the first sealing plate 120. The second sealing plate 200 can also seal the sealing tube body 100. One end of the mounting rod 210 is connected to the second sealing plate 200, and the other end of the mounting rod 210 is connected to the sensor. When the hollow drill bit 170 completes the hole opening, the hollow drill bit 170 is taken out. It should be noted that in the process of taking out the hollow drill bit 170, it is necessary to ensure the sealing state of the sealing tube body 100 to prevent the pressurized pipeline 400 from deflation. At the same time, when installing the second sealing plate 200, it is also necessary to ensure that the sealing tube body 100 is in a sealed state. After the second sealing plate 200 is connected, the mounting rod 210 extends axially to send the sensor into the pressurized pipeline 400 to complete the installation of the sensor.

[0052] Specifically, in order to ensure the realization of the above-mentioned sealing function, a closed switch is provided in the sealing tube body 100, and the closed switch is configured so that when the pipe perforating assembly or the sensor installation assembly is working, the closed switch is in an open state, and when the pipe perforating assembly or the sensor installation assembly is installed on the sealing tube body 100, that is, when the first sealing plate 120 and the second sealing plate 200 are spirally connected to the sealing tube body 100, the closed switch is in a closed state, thereby sealing the sealing tube body 100.

[0053] Specifically, the enclosed switch includes a sliding sealing plate 310 and a connecting housing 300, such as Figure 1 and Figure 8 As shown, the connection housing 300 is fixedly connected to the side wall of the sealing tube body 100 and communicates with the sealing tube body 100, and the sliding sealing plate 310 is slidably connected in the connection housing 300. The sliding sealing plate 310 slides in the connection housing 300 so that the sliding sealing plate 310 slides into the sealing tube body 100 to seal the lower end of the sealing tube body 100. When the sliding sealing plate 310 slides into the connection housing 300, the sliding sealing plate 310 no longer blocks the sealing tube body 100. The connection housing 300 is spirally connected with a handle 320, specifically, the rotating shaft of the handle 320 is spirally connected to the connection housing 300, and the end of the rotating shaft of the handle 320 is rotatably connected to the sliding sealing plate 310. The sliding sealing plate 310 can be driven to move by rotating the handle 320, and the sliding of the sliding sealing plate 310 enables the sealing tube body 100 to be sealed.

[0054] For example, when the sealing tube body 100 is installed on the pressurized pipe 400, since no holes have been drilled on the pressurized pipe 400, sealing is not required at this time. When the first sealing plate 120 is installed on the sealing tube body 100, the first sealing plate 120 seals the upper end of the sealing tube body 100. When the hollow drill bit 170 is drilling, the sealing tube body 100 is in a sealed state to prevent leakage. After drilling is completed, the drive shaft 140 is shortened, and the drive shaft 140 drives the hollow drill bit 170 to disengage from the pressurized pipe 400. Then, the handle 320 needs to be turned to slide the sliding sealing plate 310 to the sealing tube body 100 to seal the hole, thereby preventing the pressurized pipe 400 from leaking. After the sliding sealing plate 310 is sealed, the first sealing plate 120 can be removed and replaced with the second sealing plate 200. The mounting rod 210 on the second sealing plate 200 has a sensor. When the second sealing plate 200 is installed, the sealing tube body 100 is in a sealed state at this time. Therefore, the sliding sealing plate 310 can be opened, and the handle 320 is turned in the opposite direction to drive the sliding sealing plate 310 away from the sealing tube body 100 so as to no longer seal the hole. After the sliding sealing plate 310 is opened, the mounting rod 210 can be used to install the sensor.

[0055] Specifically, the connection between the sealed pipe body 100 and the pressurized pipe 400 of the present invention is connected via a welding plate 110 , and the welding connection not only has a strong connection strength but also has a sealing effect.

[0056] In a further embodiment, after the hollow drill bit 170 has completed drilling, the saddle pieces need to be collected, that is, to prevent the saddle pieces from falling into the pressurized pipe 400. A magnet (not shown in the figure) is arranged in the hollow drill bit 170, and the magnet can generate an adsorption force on the saddle pieces. When the hollow drill bit 170 is about to drill through the pressurized pipe 400, the first drive motor 130 stops driving the drive shaft 140 to rotate. At this time, the adjusting ball plate 150 no longer rotates around the axis of the sealing tube body 100, that is, the hollow drill bit 170 no longer revolves, and the hollow drill bit 170 only rotates on its own. When the hollow drill bit 170 drills through a little bit, a small part of the saddle piece is located in the hollow drill bit 170, and the magnet in the hollow drill bit 170 increases the adsorption force of the saddle piece part entering the hollow drill bit 170. At the same time, the hollow drill bit 170 begins to restore the vertical state, and the hollow drill bit 170 gradually collects the saddle pieces, thereby preventing the saddle pieces from falling into the pressurized pipe 400.

[0057] The specific working process of a pressurized pipeline opening sensor installation device provided by the present invention is described in combination with the above embodiments:

[0058] Install:

[0059] First, the sealing tube body 100 is welded to the pressurized pipe 400 through the welding plate 110 , and then the first sealing plate 120 is installed on the sealing tube body 100 . The adjusting ball plate 150 and the hollow drill bit 170 connected to the first sealing plate 120 are both located in the sealing tube body 100 .

[0060] adjust:

[0061] The telescopic part of the driving shaft 140 on the first sealing plate 120 begins to extend, and the driving shaft 140 drives the adjusting ball plate 150 to move toward the direction close to the pressurized pipe body. The two inductive telescopic rods 190 on the adjusting ball plate 150 first contact the pressurized pipe 400, and the two inductive telescopic rods 190 shorten. Then, after the hollow drill bit 170 contacts the pressurized pipe 400, the two inductive telescopic rods 190 stop shortening. The two inductive telescopic rods 190 send a signal to make the motor 152 drive the rotating gear 153 to rotate, and the rotating gear 153 and the spherical rack 160 engage. The rotating gear 153 drives the spherical rack 160 to slide on the adjusting ball plate 150, and the spherical rack 160 drives the connecting shaft 171 of the hollow drill bit 170 to slide along the through groove 154 so that the hollow drill bit 170 abuts against the pressurized pipe 400 at one end in the circumferential direction of the pressurized pipe 400.

[0062] drilling:

[0063] The first drive motor 130 and the second drive motor 180 are started. The first drive motor 130 drives the adjusting ball plate 150 to rotate around the axis of the sealing tube body 100. The adjusting ball plate 150 drives the hollow drill bit 170 to revolve. The second drive motor 180 drives the hollow drill bit 170 to rotate around its own axis. The hollow drill bit 170 rotates and revolves to evenly drill the side wall of the pressurized pipe 400, forming a uniform cutting groove around the saddle plate.

[0064] Collecting Saddle Pieces:

[0065] When the saddle plate is about to be drilled through, the first drive motor 130 stops rotating, and the adjusting ball plate 150 no longer rotates. At this time, the hollow drill bit 170 no longer revolves, but only rotates on its own. When the hollow drill bit 170 drills through the saddle plate at one end of the hollow drill bit 170 in the circumferential direction of the pressurized pipeline 400 and the part that abuts the pressurized pipeline 400, a part of the saddle plate extends into the hollow drill bit 170, and the magnet in the hollow drill bit 170 attracts the saddle plate. At the same time, the motor 152 drives the rotating gear 153 to rotate in the opposite direction to reset the spherical rack 160, and the spherical rack 160 drives the hollow drill bit 170 to reset. During the resetting process, the saddle plate is completely drilled through all around, and the saddle plate is collected by the hollow drill bit 170. The second drive motor 180 stops rotating, and the drive shaft 140 on the first sealing plate 120 begins to shorten to drive the hollow drill bit 170 and the adjusting ball plate 150 away from the pressurized pipeline 400.

[0066] To seal the hole:

[0067] After the drilling is completed, the handle 320 is turned to drive the sliding sealing plate 310 to enter the sealing tube body 100 , and the sliding sealing plate 310 seals the bottom of the sealing tube body 100 to prevent the pressurized pipeline 400 from leaking.

[0068] Install the sensor:

[0069] Remove the first sealing plate 120 and replace it with the second sealing plate 200. The installation rod 210 on the second seal is located in the sealing tube body 100. After the second sealing plate 200 is installed, rotate the handle 320 in the opposite direction to drive the sliding sealing plate 310 away from the sealing tube body 100. The sliding sealing plate 310 no longer seals the bottom of the sealing tube body 100, and the installation rod 210 starts to install the sensor.
