[0038] In some embodiments, the support frame 102 is provided with a transmission mechanism 110 at the bottom end, which is used to drive the support frame 102 to move. In the embodiment, the support frame 102 is connected with the transmission mechanism 110 through the bottom plate 101, and the transmission mechanism 110 is used to drive the support frame 102 to move in the horizontal direction; when the support frame 102 is driven by the transmission mechanism 110 to move in the horizontal direction, the hollow fiber membrane assembly is simultaneously rotated under the driving of the driving mechanism 105; the combination of the rotational movement and the horizontal movement of the hollow fiber membrane assembly forms a spiral track, which can enable the second detection assembly 104 arranged above the hollow fiber membrane assembly to continuously and gaplessly cover scan the hollow fiber membrane assembly of the detected object; such a scanning mode avoids the pause of the traditional layer-by-layer scanning, and improves the detection effect and detection efficiency; in the embodiment, the transmission mechanism 110 is a conventional conveying device in the prior art, and the specific structure and function of the transmission mechanism 110 will not be described here.

[0039] In some embodiments, the limiting frame 111 is connected with a limiting table 122, and the second detection assembly 104 is installed with a limiting assembly 112 used to cooperate with the limiting table 122.

The support wheel 116 is installed on the side of the support frame 102 away from the drive gear 118, so that the drive gear 118 and the support wheel 116 are staggered, the support points of the support wheel 116, the drive gear 118 and the hollow limiting membrane assembly are staggered, the drive gear 118 and the support wheel 116 can avoid bearing the pressure at the same position at the same time, thereby effectively dispersing the load and reducing the local stress concentration.

[0043] In some embodiments, the clamping ring 108 is slidably connected with the rotating ring 107, and the rotating ring 107 is installed with a driving part 117.

[0044] In some embodiments, the driving part 117 is rotatably connected with a rotating part at one end close to the hollow fiber membrane assembly. In the embodiment, by setting the rotating part, the friction between the driving part 117 and the clamping block generated in the process of driving the clamping ring 108 to move by the driving part 117 can be avoided, so as to avoid the abrasion of the driving part 117 and the clamping block.

[0045] In some embodiments, the first detection component 1 is provided with a light supplement lamp. The light supplement lamp is mounted on a mounting frame 121, and is used to supplement light for the detection area of the first detection component 103 when the light is dim, so as to ensure the detection effect of the first detection component 103. The light supplement lamp is a conventional light supplement device in the prior art, and the structure and function thereof will not be described here.

[0046] In some embodiments, the front and rear sides of the driven gear ring are fixedly connected with limiting plates, and the driving gear 118 is located in a limiting area formed between the two limiting plates after the driving gear 118 is engaged with the driven gear ring. Through the cooperation of the limiting plates and the driving gear 118, when the driven gear ring and the rotating ring 107 are driven to rotate by the driving gear 118, the driven gear ring will not deviate in the front and rear directions along the axis of the rotating ring 107, thereby affecting the stability in the detection of the hollow fiber membrane component.
