The mounting assembly is used to connect the detection unit and the holding rod. The mounting assembly is provided with at least two support wheels. The at least two support wheels are arranged along a first direction. The first direction is perpendicular to the rolling axis of the support wheels. In the present application, the support wheels are arranged in the detection part. The arrangement direction of the two support wheels is perpendicular to the rolling axis of the support wheels. During the detection process, the at least two support wheels can keep the distance between the detection part and the boiler water cooling wall unchanged. In addition, the detection direction of the detection part can also be kept unchanged. This is beneficial to improve the detection accuracy.

In some alternative embodiments, the holding rod 10 has a length adjusting function. For example, the holding rod 10 can be a telescopic tube in which multiple cylindrical structures are nested in sequence.

[0039] As shown in Figure 2 and Figure 3 , the handheld detection device comprises a detection part 20 arranged at one end of the holding rod 10, the detection part 20 comprises a mounting assembly 21 and a detection unit 22, the mounting assembly 21 is used to connect the detection unit 22 and the holding rod 10. The specific detection method of the detection part 20 in the embodiment is not limited, such as ultrasonic and visual methods.

[0040] As shown in Figure 2 and Figure 3 , the mounting assembly 21 is provided with at least two supporting wheels 214, which are used to support the mounting assembly 21, so that the mounting assembly 21 and the detection unit 22 mounted thereon always maintain a certain distance from the boiler water wall to meet the use requirements that the detection unit 22 can accurately detect. Referring to Figure 3 , in the first direction (x direction shown in Figure 3 ), the at least two supporting wheels 214 are arranged along the first direction, and the first direction is perpendicular to the axis direction of the rolling shaft of the supporting wheel 214. During use, the at least two supporting wheels 214 arranged along the first direction can be attached to the boiler water wall, so that the detection unit 22 always maintains the same relative posture with the boiler water wall, that is, the detection unit 22 can always maintain the same detection direction to detect defects. Here, it should be noted that during detection, the first direction can be the axial direction of the pipe to be detected, or the tangential direction of the pipe to be detected.

[0041] Exemplarily, the detection unit 22 can detect the thickness of the boiler water wall. When detecting the thickness, it is necessary to ensure that the detection direction is along the radial direction of the boiler water wall. The mounting assembly provided in the embodiment has at least two supporting wheels 214 arranged along the first direction, so as to ensure that the detection direction is always directed to the axis of the pipe to be detected.

[0042] In the embodiment, by arranging the supporting wheels in the detection part, and the arrangement direction of the two supporting wheels being perpendicular to the rolling shaft of the supporting wheel, during detection, the at least two supporting wheels can keep the distance between the detection part and the boiler water wall unchanged, and also can keep the detection direction of the detection part unchanged, which is beneficial to improve the detection accuracy.

[0044] In the embodiment, as shown in Figure 2 and Figure 3 , the mounting assembly 21 comprises a first support 211 and a second support 212, the first support 211 is used for mounting the detection unit 22 and the supporting wheel 214, the second support 212 is used for connecting the first support 211 and the holding rod 10, and the first support 211 and the second support 212 are rotationally connected around a preset rotation axis, and the axis direction of the preset rotation axis is parallel to the rolling axis of the supporting wheel 214. By rotationally connecting the first support 211 and the second support 212, when the operator continuously moves the detection part 20 on the boiler water cooling wall by pushing the detection part 20 through the holding rod 10 during use, the included angle between the extension direction of the holding rod 10 and the detection direction of the detection part 20 can be changed, and the detection direction of the detection part 20 can be kept unchanged without changing the holding mode of the user, thereby improving the detection accuracy and the detection efficiency.

[0045] Among them, as shown in Figure 2 and Figure 3 , the at least two supporting wheels 214 arranged along the first direction (x direction shown in Figure 3 ) are arranged on both sides of the preset rotation axis in the first direction. It can be determined that during use, the operator applies a force to the detection part 20 through the holding rod 10 to make the detection part 20 close to the boiler water cooling wall, and the action point of the holding rod 10 on the first support 211 through the second support 212 is located between the two supporting wheels 214, so that the two supporting wheels 214 can be tightly attached to the boiler water cooling wall, and the detection direction of the detection unit 22 can be kept unchanged.

[0046] Among them, as shown in Figure 2 and Figure 3 , the supporting wheel 214 is provided with a magnet, and the magnet arranged in the supporting wheel 214 can make the supporting wheel 214 always adsorb on the boiler water cooling wall, so as to ensure that the detection unit 22 always maintains the correct detection direction.
