[0029] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0030] A portable straight probe ultrasonic detection device, such as Figure 1 and Figure 2 As shown, it includes a detection plate 1 and an ultrasonic detection mechanism arranged on the detection plate 1, a walking mechanism is provided at the bottom of the detection plate 1, and a holding mechanism is provided at the top; the ultrasonic detection mechanism includes a mounting seat 5, and a straight probe 8 vertically slidingly arranged on the mounting seat 5, the straight probe 8 is connected to the mounting seat 5 through an elastic element 11, the length direction of the elastic element 11 is the same as the sliding direction of the straight probe 8, one end of the elastic element 11 supports the straight probe 8, and the other end supports the mounting seat 5; the walking mechanism includes walking wheels 2 arranged around the corresponding mounting seat 5 on the detection plate 1, and at least three walking wheels 2 are evenly arranged; the holding mechanism includes a telescopic rod 4, one end of the telescopic rod 4 is rotatably mounted on the detection plate 1, and the other end is provided with a handle 6.

[0031] For example, the mounting base 5 can be fixed to the inspection board 1, and the straight probe 8 can be an existing ultrasonic straight probe 8, which can be connected to an existing external device to detect flaws in an object. The present invention does not involve improvements to the straight probe 8, and therefore will not be described in detail here. In addition, the telescopic rod 4 can also be an existing manually adjustable telescopic rod, so that the operator can adjust the length of the telescopic rod 4 according to actual needs, so that the operator can conveniently use the telescopic rod 4 to drive the straight probe 8 on the inspection board 1 for inspection. This will not be described in detail here.

[0032] In actual application, by rotatably connecting the telescopic rod 4 to the detection plate 1 and providing the running wheels 2 on the detection plate 1, the operator can use the running wheels 2 to fit the surface of the object, and then use the telescopic rod 4 to push the detection plate 1 along the surface of the object. At this time, since the telescopic rod 4 is rotatably connected to the detection plate 1 and the running wheels 2 on the detection plate 1 fit the surface of the object, the operator can conveniently use the telescopic rod 4 to drive the detection plate 1 to move stably, which is conducive to improving the detection effect. At the same time, the straight probe 8 on the detection plate 1 can also be closer to the surface of the object when the elastic element 11 is used for detection, which is conducive to further improving the detection effect and accuracy.

[0033] Optionally, the mounting seat 5 is provided with a receiving groove 12 for accommodating the straight probe 8 and the elastic element 11; the straight probe 8 is slidably installed on the mounting seat 5 through the slider 9, and a sliding groove 10 that cooperates with the slider 9 is provided at a position corresponding to the receiving groove 12 on the mounting seat 5, and the sliding groove 10 is connected to the receiving groove 12.

[0034] Exemplarily, at least two sliders 9 are evenly arranged along the circumference of the straight probe 8. Specifically, two or more sliders 9 can be evenly arranged, and each slider 9 can be fixed to the straight probe 8 by gluing or welding, or can be fixed to the straight probe 8 by screws. Those skilled in the art can also choose other methods to install and fix the sliders 9 according to actual needs to achieve a stable connection between the sliders 9 and the straight probe 8. This will not be repeated here.

[0035] In actual use, the receiving groove 12 opens downward, and the elastic element 11 is a compression spring, with one end of the compression spring supporting the top surface of the receiving groove 12 and the other end supporting the straight probe 8. To facilitate wiring of the straight probe 8, a wire hole can be provided on the mounting base 5 at a position corresponding to the receiving groove 12, and the wire hole is connected to the receiving groove 12. Furthermore, to facilitate assembly of the elastic element 11 and the straight probe 8, the mounting base 5 can also be a split structure, with the upper half 14 and the lower half 13 connected by threads, for example, with external threads on the upper half 14 and internal threads on the lower half 13 corresponding to the receiving groove 12 that mate with the external threads.

[0036] Optionally, a circular bracket 7 is provided on the telescopic rod 4 at a position corresponding to the position above the handle 6. For example, the circular bracket 7 is fixed to the telescopic rod 4. By providing the circular bracket 7 on the telescopic rod 4 at a position corresponding to the position above the handle 6, when using the detection device, the operator can pass the arm through the circular bracket 7 and then hold the handle 6 with the hand, which is conducive to distributing the force and reducing the difficulty of holding and using the detection device.

[0037] Optionally, the handle 6 is rotatably mounted on the telescopic rod 4. For example, the handle 6 can be rotatably mounted on the telescopic rod 4 via a rotating shaft, with a bearing seat for mounting the rotating shaft fixed to the telescopic rod 4. Those skilled in the art may also select other methods of mounting the handle 6 according to actual needs to facilitate the operator's use of the handle 6, and this will not be described in detail here.

[0038] In actual use, an anti-slip cover is provided on the handle 6. For example, the anti-slip cover can be a rubber cover and fixed to the handle 6 by adhesive. The provision of the anti-slip cover helps prevent the operator from dropping the handle 6 when using it, and helps improve the stability of the detection device during mobile detection.

[0039] Since the existing detection device needs to be directly grasped by the hand on the telescopic rod 4, it is necessary to use the force of the wrist to move the device body left and right for flaw detection, which is easy to cause wrist injury. In this embodiment, a handle 6 is added to the telescopic rod, which makes the hand-holding posture more convenient. By adding a circular ring bracket 7, the force can be distributed to the entire arm, and the force on the arm is used to drive the device body to move left and right. The hand controls the direction, thereby improving the detection speed, saving labor, and reducing the loss of the straight probe and the straight probe external cable.

[0040] Optionally, a rotating frame 3 for mounting the telescopic rod 4 is provided on the detection plate 1, wherein one end of the rotating frame 3 is rotatably mounted on the detection plate 1, and the other end is connected to the telescopic rod 4. Exemplarily, the rotating frame 3 is a Y-shaped structural member, wherein the two oblique ends of the rotating frame 3 are both rotatably connected to the detection plate 1, and the vertical end is fixedly connected to the telescopic rod 4. Among them, the two oblique ends of the rotating frame 3 can be rotatably connected to the detection plate 1 through a rotating shaft, and the detection plate 1 is provided with an axial hole that cooperates with the rotating shaft. By adopting a Y-shaped rotating frame 3 to connect the telescopic rod 4 and the detection plate 1, it is beneficial to improve the structural strength and stability of the connection between the telescopic rod 4 and the detection plate 1, and it is convenient for the operator to use the telescopic rod 4 to drive the detection plate 1 to move or rotate, so that the straight probe 8 on the detection plate 1 can stably and accurately detect the object to be measured.

[0041] Optionally, the walking wheel 2 is a universal caster. For example, the universal caster can be fixed to the detection plate 1 by screws. By providing the universal caster, the movement range of the detection plate 1 is increased, and the operator can use the telescopic rod 4 to move the detection plate 1 flexibly, thereby improving the flexibility of the detection device.

[0042] The portable straight probe ultrasonic detection device described in the present invention has the advantages of simple structure, easy operation and flexible use. It can ensure that the straight probe is stably close to the surface of the object to be detected for detection, which is conducive to improving the ultrasonic detection effect. By rotating the telescopic rod and the detection plate, and providing running wheels on the detection plate, the operator can use the running wheels to fit the surface of the object, and then use the telescopic rod to push the detection plate to move along the surface of the object. At this time, since the telescopic rod is rotatably connected to the detection plate, and the running wheels on the detection plate cooperate with the surface of the object, the operator can conveniently use the telescopic rod to drive the detection plate to move stably, which is conducive to improving the detection effect. At the same time, the straight probe on the detection plate can also be closer to the surface of the object for detection when the elastic element is better, which is conducive to further improving the detection effect and accuracy.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
