Description

Technical Field

[0001] The utility model relates to a probe device for ultrasonic flaw detection, in particular to a non-contact phased array probe water bag. Background Art

[0002] When using a phased array probe to detect the circumferential weld of a pipe, most of the existing flaw detection devices are contact type or water immersion type. Among them, for the contact type flaw detection device, such as an array ultrasonic probe device for detecting transverse defects of large-diameter steel pipes disclosed in a Chinese patent with the publication number of "CN113358744A", its ultrasonic probe directly contacts the pipe to be detected, so as to effectively detect the pipe. For the water immersion type flaw detection device, its probe is entirely immersed below the water surface, so as to perform ultrasonic flaw detection on the pipe in the water.

[0003] Both of the above two detection methods have certain problems. Specifically, for contact type flaw detection, since the probe directly contacts the pipe, and the surface of the pipe may be uneven, this will affect the coupling between the probe and the pipe, thus affecting the flaw detection effect. For water immersion type flaw detection, the requirements for the detection environment are relatively high. When detecting large pipes, large water tanks and corresponding hoisting devices need to be set up, and the operation is relatively inconvenient. Moreover, the part of the pipe to be detected needs to be completely immersed in water during detection, so a large amount of water resources are consumed during the detection process, thus increasing the detection cost. Summary of the Invention

[0004] To solve the above technical problems, the utility model provides a non-contact phased array probe water bag which is suitable for pipes with uneven surfaces, consumes less water resources, is convenient to operate, and has good flaw detection effect.

[0005] The non-contact phased array probe water bag of the utility model includes a detection probe. The non-contact phased array probe water bag further includes a bag body with a cavity inside. The bottom of the bag body has a water outlet communicating with the inner cavity of the bag body. A plurality of water inlets communicating with the inner cavity of the bag body are arranged on the bag body wall. The detection probe is arranged in the cavity of the bag body and corresponds to the water outlet.

[0006] The advantage of this non-contact phased array probe water bag is that a detection probe corresponding to the water outlet is arranged in the inner cavity of the bag body. The bottom of the bag body has a water outlet, and a plurality of water inlets are also arranged on the bag body wall.

[0007] Through the arrangement of the water inlets and the water outlet, the non-contact phased array probe water bag can input external high-pressure water source into the inner cavity of the bag body through the water inlets, and then output it from the water outlet at the bottom of the bag body to form a water column and spray it onto the surface of the pipe to be detected. In this way, the detection probe corresponding to the water outlet in the inner cavity of the bag body can be coupled with the pipe surface through the water column formed at the water outlet, so as to perform ultrasonic flaw detection on the pipe.

[0008] Compared with the contact ultrasonic flaw detection device, this non-contact phased array probe water package can achieve coupling with the pipeline to be detected through a water column, thus avoiding the influence of the uneven surface of the pipeline on flaw detection.

[0009] Compared with the immersion ultrasonic flaw detection device, when using this non-contact phased array probe water package for flaw detection, there is no need to set up a special detection water tank and hoisting equipment. Only an external high-pressure water pump is needed to achieve the coupling between the detection probe and the pipeline, thus reducing the detection cost. At the same time, when detecting, only a small amount of water column sprayed from the water outlet is needed to achieve coupling with the pipeline. Compared with the full immersion detection, it saves a large amount of water resources and is also more convenient to operate.

[0010] Furthermore, for this non-contact phased array probe water package of the present utility model, the package body includes an upper part of the package body and a lower part of the package body. The upper part of the package body is in the shape of a cuboid, and the lower part of the package body is in the shape of an inverted truncated quadrangular pyramid.

[0011] The inverted truncated quadrangular pyramid-shaped lower part of the package body increases the pressure when the water flows out through the water outlet at the bottom of the package body, so that it is easier to form a continuous water column, thereby improving the coupling effect between the detection probe and the pipeline.

[0012] Furthermore, for this non-contact phased array probe water package of the present utility model, a probe mounting frame is arranged inside the package body. The probe mounting frame includes a connecting plate fixedly connected to the package body at one end and a mounting plate fixedly connected to the connecting plate at one end. The detection probe is fixedly arranged on the mounting plate.

[0013] The setting of the probe mounting frame realizes the installation of the detection probe.

[0014] Among them, the mounting plate can be inclined to facilitate the flow of water to form a continuous water column, and its inclination angle can be specifically adjusted according to requirements.

[0015] Furthermore, for this non-contact phased array probe water package of the present utility model, transmission holes penetrating the mounting plate are provided on the surface of the mounting plate, and the detection probe is located above the transmission holes.

[0016] The setting of the transmission holes enables the ultrasonic signal to be output to the water outlet of the package body and the surface of the pipeline through the transmission holes, and the echo signal reflected by the pipeline can be transmitted to the detection probe through the transmission holes.

[0017] Furthermore, for this non-contact phased array probe water package of the present utility model, a flow guide plate is also provided on the probe mounting frame. One end of the flow guide plate is fixedly connected to the probe mounting frame, and the other end of the flow guide plate is located at the water outlet.

[0018] The setting of the flow guide plate enables the water flow in the package body to better form a continuous water column under the guidance of the flow guide plate, thereby improving the coupling performance between the detection probe and the pipeline.

[0019] Furthermore, for the non-contact phased array probe water bag of the present utility model, a number of flow guiding corrugations are provided on the surface of the flow guiding plate.

[0020] The provision of the flow guiding corrugations further improves the flow guiding performance of the flow guiding plate for high-pressure water flow.

[0021] Furthermore, for the non-contact phased array probe water bag of the present utility model, both the transmission hole and the water outlet are rectangular holes.

[0022] The rectangular transmission hole and water outlet can match the detection signal output from the output end of the detection probe, thereby improving the effectiveness of signal transmission and the flaw detection effect.

[0023] Furthermore, for the non-contact phased array probe water bag of the present utility model, four water inlets are provided on the bag body, and the four water inlets are respectively located on the four side walls of the front, back, left and right of the bag body.

[0024] The provision of the four water inlets facilitates the connection of the bag body to an external high-pressure water source.

[0025] Furthermore, for the non-contact phased array probe water bag of the present utility model, a support seat and a connecting rod connected to the support seat are provided on the top wall of the bag body. The other end of the connecting rod is fixedly connected to a support rod, and the bottom end of the support rod is fixedly provided on the base.

[0026] The provision of the support seat, the connecting rod, the support rod and the base realizes the installation and positioning of the bag body.

[0027] Furthermore, for the non-contact phased array probe water bag of the present utility model, a cable interface is provided on the top wall of the bag body.

[0028] The provision of the cable interface realizes the connection between the detection probe and the flaw detection host.

In order to be able to more clearly understand the technical means of the present utility model and implement it specifically according to the content of the description, the following uses the embodiments of the present utility model to describe it in detail.

Specific implementation manners

[0038] The following will further describe in detail the specific implementation manners of the present utility model in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present utility model, but not to limit the scope of the present utility model.

[0039] Embodiment 1: Refer to Figures 1 to 5 , the non-contact phased array probe water bag of this embodiment includes a detection probe 1. The non-contact phased array probe water bag further includes a package body 2 with an internal cavity. The bottom of the package body has a water outlet 3 communicating with the internal cavity of the package body. A plurality of water inlets 4 communicating with the internal cavity of the package body are provided on the package body wall. The detection probe is arranged in the cavity of the package body and is corresponding to the water outlet.

[0040] The advantage of this non-contact phased array probe water bag is that a detection probe corresponding to the water outlet is arranged in the internal cavity of the package body. The bottom of the package body has a water outlet, and a plurality of water inlets are also provided on the package body wall.

[0041] Through the arrangement of the water inlets and water outlets, the non-contact phased array probe water bag can input external high-pressure water source into the internal cavity of the package body through the water inlets, and then output it from the water outlet at the bottom of the package body to form a water column and spray it onto the surface of the pipe to be inspected. In this way, the detection probe corresponding to the water outlet in the internal cavity of the package body can be coupled with the pipe surface through the water column formed at the water outlet, so as to perform ultrasonic flaw detection on the pipe.

[0042] Compared with the contact type ultrasonic flaw detection device, this non-contact phased array probe water bag can be coupled with the pipe to be inspected through the water column, thus avoiding the influence of the uneven surface of the pipe on the flaw detection.

[0043] Compared with the immersion ultrasonic flaw detection device, when the non-contact phased array probe water bag is used for flaw detection, there is no need to set up a special detection water tank and hoisting equipment. Only an external high-pressure water pump is needed to realize the coupling between the detection probe and the pipeline, thus reducing the detection cost. At the same time, when detecting, only a small amount of water column ejected from the water outlet is needed to realize the coupling with the pipeline. Compared with the full immersion detection, it saves a large amount of water resources and is also more convenient to operate.

[0044] During specific detection, the operator connects the water inlet on the package body to the high-pressure water source through the pipeline and blocks the redundant water inlets with plugs. The detection probe in the package body is connected to the external flaw detection host through a cable.

[0045] Then, the operator places the pipeline to be detected under the package body and aligns the water outlet at the bottom of the package body with the part of the pipeline to be detected.

[0046] During detection, the pipeline can rotate under the drive of an external rotating device. While the pipe rotates, the high-pressure water source enters the inner cavity of the package body from the water inlet and is output from the water outlet of the package body to the surface of the pipeline. At this time, the ultrasonic signal output by the detection probe can be transmitted to the surface of the pipeline through the water column formed at the water outlet, and the pipeline echo is also transmitted in the reverse direction to the detection probe by this water column, thus forming an echo signal. The detection probe transmits the echo signal to the flaw detection host at the far end through the cable, and the flaw detection host conducts corresponding analysis, so as to realize non-contact flaw detection of the pipeline.

[0047] Among them, the detection probe corresponding to the water outlet means that the signal output by the detection probe can be output through the water outlet. Preferably, the input and output ends of the ultrasonic probe can be directly arranged directly above the water outlet.

[0048] Preferably, the package body includes an upper part 5 of the package body and a lower part 6 of the package body. The upper part of the package body is rectangular parallelepiped-shaped, and the lower part of the package body is an inverted truncated quadrangular pyramid-shaped.

[0049] The inverted truncated quadrangular pyramid-shaped lower part of the package body increases the pressure when the water flows out of the water outlet at the bottom of the package body, so that it is easier to form a continuous water column, and further improves the coupling effect between the detection probe and the pipeline.

[0050] Preferably, a probe mounting rack is arranged in the package body. The probe mounting rack includes a connecting plate 7 with one end fixedly connected to the package body and a mounting plate 8 with one end fixedly connected to the connecting plate. The detection probe is fixedly arranged on the mounting plate.

[0051] The setting of the probe mounting rack realizes the installation of the detection probe.

[0052] Among them, the mounting plate can be inclined to facilitate the flow of water to form a continuous water column, and its inclination angle can be specifically adjusted according to requirements.

[0053] Preferably, a transmission hole 9 penetrating the mounting plate is provided on the surface of the mounting plate, and the detection probe is located above the transmission hole.

[0054] The arrangement of the transmission hole enables the ultrasonic signal to be output through the transmission hole to the water outlet of the package body and the surface of the pipeline, and the echo signal reflected by the pipeline can be transmitted to the detection probe through the transmission hole.

[0055] Preferably, a flow guide plate 10 is further provided on the probe mounting bracket. One end of the flow guide plate is fixedly connected to the probe mounting bracket, and the other end of the flow guide plate is located at the water outlet.

[0056] The arrangement of the flow guide plate enables the water flow in the package body to better form a jet of water under the guidance of the flow guide plate, thereby improving the coupling performance between the detection probe and the pipeline.

[0057] Preferably, a plurality of flow guide corrugations are provided in parallel on the surface of the flow guide plate.

[0058] The arrangement of the flow guide corrugations further improves the flow guiding performance of the flow guide plate for high-pressure water flow.

[0059] In this embodiment, the mounting plate is inclinedly arranged at the bottom end of the connecting plate, the top end of the connecting plate is fixedly arranged on the top wall of the package body, the top end of the flow guide plate is located at the transmission hole and is fixedly connected to the mounting plate or the connecting plate.

[0060] The included angle between the flow guide plate and the mounting plate is greater than 90 degrees. Due to the inclined arrangement of the mounting plate, the high-pressure water flow is transmitted to the surface of the flow guide plate which is cross-arranged with it through the inclined mounting plate, and is transmitted to the water outlet at the bottom end of the flow guide plate under the action of the flow guide corrugations on the surface of the flow guide plate, thereby forming a jet of water and being transmitted to the surface of the pipeline.

[0061] The ultrasonic signal output by the detection probe is transmitted to the water outlet through the transmission port and the water column, and is transmitted to the surface of the pipeline by the water outlet. The pipeline echo is transmitted to the detection probe along the reverse path, thereby realizing flaw detection.

[0062] Preferably, both the transmission hole and the water outlet are rectangular holes.

[0063] The rectangular transmission hole and water outlet can match the detection signal output by the output end of the detection probe, thereby improving the effectiveness of signal transmission and the effect of flaw detection.

[0064] Preferably, four water inlets are provided on the package body, and the four water inlets are respectively located on the four side walls of the front, back, left and right of the package body.

[0065] The arrangement of the four water inlets facilitates the connection between the package body and an external high-pressure water source.

[0066] Specifically, the operator can connect the pipeline to the water inlet of the package body from four directions and block the other three water inlets, thereby realizing the connection between the high-pressure water source and the package body.

[0067] Embodiment 2: Refer to Figures 6 to 7 , the non-contact phased array probe water package of this embodiment adds the following technical content on the basis of the non-contact phased array probe water package of Embodiment 1. Specifically, for the non-contact phased array probe water package of this embodiment, a support seat 11 and a connecting rod 12 connected to the support seat are provided on the top wall of the package body. The other end of the connecting rod is fixedly connected to a support rod 13, and the bottom end of the support rod is fixedly arranged on a base 14.

[0068] The settings of the support seat, connecting rod, support rod and base realize the installation and positioning of the package body.

[0069] Preferably, a cable interface 15 is provided on the top wall of the package body.

[0070] The setting of the cable interface realizes the connection between the detection probe and the flaw detector host.

[0071] Among them, the detection probe is a phased array probe, which can emit or receive ultrasonic signals. Its cable is connected to the flaw detector host through the cable interface. There are corresponding seals between the cable and the detection probe and the package body to prevent the leakage of water flow during detection. The pipe to be inspected 16 is a round pipe or a special-shaped pipe.
