Description

Technical Field

[0001] The utility model relates to the technical field of pipeline detection, in particular to a heating pipeline leakage detection device. Background Art

[0002] In cold areas, rooms are heated in winter to ensure the room temperature. When heating a room, heating pipes are needed. However, during the long-term use of the pipes, the pipes will crack and cause water leakage. It is necessary to use detection devices to detect the location of the pipeline leakage.

[0003] For example, a pipeline leakage detection device with Chinese publication number CN214580522U includes an ultrasonic flaw detector, an upper arc plate and a lower arc plate, a mounting hole is opened at the center of the top outer wall of the upper arc plate, a mounting tube is fixedly connected in the mounting hole, a probe of the ultrasonic flaw detector is plugged into the mounting tube, a first plug-in slot and a second plug-in slot are respectively opened on the outer walls of the left and right ends of the upper arc plate, two top ends of the lower arc plate are respectively plugged into the first plug-in slot and the second plug-in slot, a spring is fixedly connected in the second plug-in slot, a connecting piece is welded at the end of the spring, the end of the connecting piece is hinged to the end of the lower arc plate, and an arc hole is opened on one side of the inner wall of the second plug-in slot;

[0004] This technical solution uses an ultrasonic flaw detector to inspect pipelines. The ultrasonic flaw detector uses the influence of the acoustic properties of the material and the changes in the internal structure of the material on the propagation of ultrasonic waves when ultrasonic waves propagate in the material being inspected. The material performance and structural changes are understood by detecting the degree of influence and condition of the ultrasonic waves. The air between the ultrasonic probe and the surface of the workpiece being inspected will hinder the transmission of ultrasonic waves into the workpiece. In order for the ultrasonic wave to effectively penetrate the workpiece being inspected and to ensure that there is sufficient sound intensity transmittance on the detection surface to achieve the purpose of detection, a coupling agent needs to be applied to the pipeline before detection. The current method of applying the coupling agent is to apply it manually before detection. Since there are a large number of heating pipes and they are long, manual application will delay the detection time. Utility Model Content

[0005] In order to make up for the above deficiencies, the utility model provides a heating pipeline leakage detection device.

[0006] The utility model is achieved in this way:

[0007] A heating pipeline leakage detection device comprises an ultrasonic flaw detector body and a coating mechanism, wherein the ultrasonic flaw detector body comprises a controller and a detection probe, wherein a wire is electrically connected between the controller and the detection probe, wherein the coating mechanism comprises a coating base and a material storage box, wherein the material storage box is mounted on the top of the coating base, wherein the coating base and the material storage box are both ring-mounted, wherein the detection probe is located in the inner ring of the material storage box, wherein the outer shell of the detection probe is connected to the inner ring wall of the coating base, wherein a plurality of discharge holes are equidistantly provided at the bottom of the material storage box, wherein a connecting ring is provided inside the discharge hole, wherein a plurality of feed holes are equidistantly provided at the top of the coating base, wherein a plurality of sliding holes connected to the feed holes are equidistantly provided inside the coating base, wherein a plurality of openings connected to the sliding holes are equidistantly provided at the bottom of the coating base, wherein the feed hole is truncated cone-shaped, wherein a cover plate sliding in the feed hole is provided at the bottom of the feed hole, wherein a spring is connected between the top of the cover plate and the connecting ring, wherein a shaft sleeve sliding in the sliding hole is installed at the bottom of the cover plate, wherein a ball sliding in the opening is embedded in the inner bottom of the shaft sleeve.

[0008] The beneficial effect of adopting the above further scheme is that the storage box is filled with coupling agent. When the device is not used, the spring presses the cover plate to the bottom of the feed hole, thereby blocking the feed hole. At this time, the coupling agent cannot flow out through the feed hole. When inspecting the pipeline, it is necessary to press the detection probe on the pipeline and move the detection probe to conduct a comprehensive inspection of the pipeline. During this process, the ball moves upward due to pressure. Since the ball is embedded in the inner bottom of the sleeve, it cannot move upward, so it will cause the sleeve to move upward, thereby causing the cover plate to move upward in the feed hole. Because the feed hole is truncated cone-shaped, after the cover plate moves up, the coupling agent will flow out from the gap between the cover plate and the feed hole, and enter the opening through the gap between the sleeve and the sliding hole, and finally drip on the pipe, so that the coupling agent is sprinkled around the detection probe. As the coating base moves, the coupling agent is then coated on the pipe, and then the detection probe moves to the coating location to detect the pipe, so as to achieve the effect of coating the coupling agent on the pipe while detecting the pipe, and finally improve the detection efficiency of the pipe without affecting the detection accuracy.

[0009] Furthermore, four groups of connecting strips are connected between the side surface of the connecting ring and the discharge hole. The connecting ring is located at the center of the discharge hole, and a gap is left between the outer side of the connecting ring and the hole wall of the discharge hole.

[0010] The beneficial effect of adopting the above further solution is that the coupling agent can flow from the gap and the inner ring of the connecting ring into the feed hole.

[0011] Furthermore, a support plate is installed at the bottom of the feed hole, the cover plate is fitted with the support plate, a slide groove is opened at the center of the support plate, and the shaft sleeve slides in the slide groove.

[0012] Furthermore, a sealing ring is installed at the bottom of the cover plate, and a sealing groove is opened at the top of the support plate, and the sealing ring and the sealing groove are engaged with each other.

[0013] The beneficial effect of adopting the above further scheme is that the support plate is used to support the cover plate so that it will not be suspended in the feed hole, thereby improving the sealing of the cover plate to the feed hole when stationary, and at the same time using a sealing ring and a sealing groove to improve the sealing between the support plate and the feed hole.

[0014] Furthermore, the number of the feed holes and the number of the discharge holes are the same.

[0015] Furthermore, a feed trough is provided on the top of the material storage box, a feed pipe is installed on the top of the feed trough, and a one-way valve is connected to the top of the feed pipe.

[0016] The beneficial effect of adopting the above further solution is that the coupling agent is injected into the storage box through the feed pipe and the feed slot, and the one-way valve can prevent the coupling agent from flowing out of the feed pipe.

[0017] Furthermore, a display screen and a plurality of control keys are provided on the top of the controller, interfaces are installed on one side of the controller and on the top of the detection probe, and both ends of the wire are electrically connected to the interface.

[0018] The beneficial effect of adopting the above further solution is that the interface is used to make the wire detachable, so that the wire can be replaced, thereby allowing the user to use a wire of appropriate length.

[0019] The beneficial effects of the utility model are as follows: the utility model obtains a heating pipeline leakage detection device through the above design, the storage box is filled with coupling agent, when the device is not used, the spring presses the cover plate to the bottom of the feed hole, thereby blocking the feed hole, and the coupling agent cannot flow out through the feed hole. When the pipeline is detected, the detection probe needs to be pressed on the pipeline, and the detection probe is moved to perform a comprehensive detection of the pipeline. During this process, the ball is pressed and moves upward, because the ball is embedded in the inner bottom of the sleeve, it cannot move upward, so it will cause the sleeve to move upward, thereby The cover plate is moved up in the feed hole. Since the feed hole is a truncated cone, after the cover plate is moved up, the coupling agent will flow out from the gap between the cover plate and the feed hole, and enter the opening through the gap between the shaft sleeve and the sliding hole, and finally drip on the pipe, so that the coupling agent is sprinkled around the detection probe. As the coating base moves, the coupling agent is further coated on the pipe, and then the detection probe moves to the coating position to detect the pipe, so as to achieve the effect of coating the coupling agent on the pipe while detecting the pipe, and finally improve the detection efficiency of the pipe without affecting the detection accuracy.

The inner bottom is embedded with a ball 2010 that slides in the opening 2014. The storage box 2002 is filled with coupling agent. When the device is not used, the spring 2006 presses the cover plate 2007 on the bottom of the feed hole 2012, thereby blocking the feed hole 2012. At this time, the coupling agent cannot flow out through the feed hole 2012. When testing the pipeline, the detection probe 1002 needs to be pressed on the pipeline and the detection probe 1002 needs to be moved to fully test the pipeline. During this process, the ball 2010 is pressed and moves upward. Because the ball 2010 is embedded in the inner bottom of the sleeve 2009, it cannot move upward, so it will cause the sleeve 2009 to move upward, thereby causing the cover plate 2007 to move upward. Move upward in the feed hole 2012.

[0035] Embodiment 3 of a heating pipeline leakage detection device of the utility model

[0036] Reference Figure 1-Figure 7 Specifically, a display screen and several control keys are provided on the top of the controller 1001, interfaces are installed on one side of the controller 1001 and the top of the detection probe 1002, both ends of the wire 1003 are electrically connected to the interface, and the interface is used to make the wire 1003 detachable so that the wire 1003 can be replaced, so that the user can use the wire 1003 of appropriate length. The controller 1001 has a built-in battery for powering the controller 1001 and the detection probe 1002. The detection probe 1002 sends the changes in ultrasonic waves to the controller 1001, and the results are reflected on the display screen after being processed by its internal processor.

[0037] Specifically, the working principle of the heating pipeline leakage detection device is as follows: when in use, the coupling agent is injected into the storage box 2002 through the feed pipe 2004 and the feed trough 2003. When detecting the pipeline, the detection probe 1002 needs to be pressed on the pipeline, and the detection probe 1002 needs to be moved to conduct a comprehensive detection of the pipeline. During this process, the ball 2010 moves upward due to pressure. Since the ball 2010 is embedded in the inner bottom of the sleeve 2009, it cannot move upward, so it will cause the sleeve 2009 to move upward, thereby causing the cover plate 2007 to move upward in the feed hole 2012. Since the feed hole 2012 is a circle Therefore, after the cover plate 2007 moves up, the coupling agent will flow out from the gap between the cover plate 2007 and the feed hole 2012, and enter the opening 2014 through the gap between the shaft sleeve 2009 and the sliding hole 2013, and finally drip on the pipe, so that the coupling agent is sprinkled around the detection probe 1002. With the movement of the coating base 2001, the coupling agent is further coated on the pipe. Then the detection probe 1002 moves to the coating position to detect the pipe, and sends the changes in the ultrasonic wave to the controller 1001 through the wire 1003. After being processed by its internal processor, the results are reflected on the display screen.
