[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0032] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0033] Example 1, reference Figure 1 and Figure 2 , which is the first embodiment of the present invention, provides a tube sleeve type structure fluorescence detection device, which includes an installation unit 100, a detection unit 200 and a conveying unit 300.

[0034] The mounting unit 100 includes a mounting cover 101, a stopper assembly 102 disposed outside the mounting cover 101, a mounting plate 103 rotatably disposed at the end of the mounting cover 101, a transition tube 104 disposed inside the mounting cover 101, and a connecting tube 105 disposed in the transition tube 104;

[0035] The connecting tube 105 is disposed through the transition tube 104 , and the connecting tube 105 , the transition tube 104 and the mounting plate 103 are coaxially disposed.

[0036] Furthermore, the limiting assembly 102 includes a plurality of elastic plates 102a disposed on the outside of the mounting cover 101, a mounting seat 102b disposed in the middle of the elastic plates 102a, and a roller 102c rolling on the mounting seat 102b, wherein three elastic plates 102a are preferably provided.

[0037] The detection unit 200 includes a cleaning component 201 arranged on the outside of the transition cylinder 104 and connected to the mounting plate 103, a spray component 202 arranged at the end of the connecting cylinder 105 and connected to the mounting plate 103, a driving component 203 arranged on the mounting plate 103, and a monitoring camera 204 arranged on the mounting plate 103.

[0038] Furthermore, the conveying unit 300 includes a cleaning tube 301 disposed at the end of the transition tube 104 and a fluorescent tube 302 disposed at the end of the connecting tube 105 , wherein the cleaning tube 301 conveys cleaning liquid inside; and the fluorescent tube 302 conveys fluorescent liquid inside.

[0039] Furthermore, the driving assembly 203 includes a driving motor 203a arranged on the mounting plate 103, a ring gear 203b arranged on the inner side of the mounting cover 101, and a gear 203c arranged at the end of the driving motor 203a and meshing with the ring gear 203b. The driving motor 203a drives the gear 203c to rotate, thereby controlling the mounting plate 103 to rotate relative to the mounting cover 101, and further drives the spraying assembly 202 and the cleaning assembly 201 to rotate.

[0040] During use, the installation cover 101 is plugged into the inside of the pipeline, and the installation cover 101 can be transported into the inside of the pipeline by transporting the fluorescent tube 302 and the cleaning tube 301 into the inside of the pipeline. When the installation cover 101 moves to the connection between the tube and the sleeve, the fluorescent liquid is transported into the inside of the connecting tube 105 through the fluorescent tube 302, and the fluorescent liquid is finally sprayed out from the spray component 202 and attached to the weld. The mounting plate 103 is driven to rotate by the driving motor 203a, and the sleeve weld is sprayed in all directions. After that, the cleaning liquid is transported into the inside of the transition tube 104 through the cleaning tube 301, and the cleaning liquid is finally sprayed out from the end of the cleaning component 201 to flush the fluorescent liquid. Whether there is any fluorescent liquid residue at the weld can be observed to determine whether the weld has defects.

[0041] Example 2, reference Figure 3 , which is the second embodiment of the present invention, and this embodiment is different from the first embodiment in that: the spray assembly 202 includes a rotating cover 202a rotatably disposed at the end of the connecting tube 105, a sealing arrangement between the rotating cover 202a and the connecting tube 105, a hose 202b disposed in the rotating cover 202a, a nozzle 202c disposed at the end of the hose 202b, a nozzle 202d disposed at the end of the nozzle 202c, and a telescopic portion 202e disposed in the mounting plate 103 and connected to the nozzle 202c;

[0042] The end of the nozzle 202c slides out of the mounting plate 103.

[0043] Furthermore, the telescopic portion 202e includes an electric telescopic rod 202e-1 arranged on the mounting plate 103, and a mounting block 202e-2 arranged at the end of the electric telescopic rod 202e-1; the bottom of the nozzle 202c is installed on the mounting block 202e-2, and the operation of the electric telescopic rod 202e-1 can drive the mounting plate 103 and the nozzle 202c to move. When the nozzle 202c moves, it can extend out of the mounting plate 103. When spraying fluorescent liquid at the weld, the nozzle 202c can be inserted into the inside of the support between the tube sleeves, and the fluorescent liquid is sprayed along the weld. Since the rotating cover 202a rotates at the end of the connecting tube 105, when the mounting plate 103 and the electric telescopic rod 202e-1 rotate, the rotating cover 202a will be driven to rotate synchronously, which can prevent the internal hose 202b from being entangled.

[0044] When spraying fluorescent liquid on the welds between multiple support members, it is only necessary to first extend the nozzle 202c to spray the fluorescent liquid, then retract the nozzle 202c, control the mounting plate 103 to rotate and drive the nozzle 202c to stop rotating as it rotates to the next support member, and then extend the nozzle 202c again to spray the fluorescent liquid. By performing multiple extensions and rotations of the nozzle 202c, the fluorescent liquid can be sprayed in all directions on the multiple welds between the sleeves.

[0045] Furthermore, the cleaning assembly 201 includes an annular cover 201a rotatably disposed on the outside of the transition tube 104, a sealing arrangement between the annular cover 201a and the transition tube 104, a through groove 201b disposed on the transition tube 104 and communicating with the annular cover 201a, a support tube 201c disposed on the annular cover 201a and connected to the mounting plate 103, and a nozzle 201d disposed at the end of the support tube 201c.

[0046] After the spraying of the fluorescent liquid on the weld is completed, the nozzle 202c is retracted, and then the cleaning liquid is introduced into the interior of the transition tube 104 through the cleaning tube 301. The cleaning liquid enters the annular cover 201a from the groove 201b, and finally passes through multiple support tubes 201c and is sprayed out from multiple nozzles 201d, thereby cleaning the fluorescent liquid on the welds distributed in a circular shape. Then, the mounting plate 103 is controlled to rotate, thereby driving the camera to move in a circle to observe the fluorescent liquid remaining on the multiple welds.

[0047] The remaining structures are the same as those of Example 1.

[0048] Example 3, reference Figure 4 , which is the third embodiment of the present invention, and this embodiment is different from the second embodiment in that: the mounting plate 103 is plugged into the end of the mounting cover 101 and can be extended and retracted along the mounting cover 101;

[0049] A pressurizing part 201e is provided inside the transition tube 104;

[0050] An extension ring 201a - 1 is provided on the annular cover 201a , and the annular cover 201a is slidably arranged on the transition tube 104 . The extension ring 201a - 1 matches with the through groove 201b , and a reset portion 201f is provided between the annular cover 201a and the mounting cover 101 .

[0051] Among them, the boosting part 201e includes a spring 201e-1 arranged inside the transition tube 104, a piston ring 201e-2 arranged at the end of the spring 201e-1, and a vent hole 201e-3 arranged on the transition tube 104; the piston ring 201e-2 is slidably sleeved on the connecting tube 105, and the piston ring 201e-2 is sealed with the inner wall of the transition tube 104 and the outer wall of the connecting tube 105.

[0052] Among them, the reset part 201f includes a rotating ring 201f-1 rotatably set on the mounting cover 101, and a spring 201f-2 set between the rotating ring 201f-1 and the annular cover 201a. In the initial state, the small spring 201f-2 is in an extended state. At this time, the extension ring 201a-1 overlaps with the through groove 201b to close the transition tube 104. When the cleaning tube 301 injects cleaning liquid into the interior of the transition tube 104, it squeezes the piston ring 201e-2 and compresses the spring 201e-1, so that a large amount of cleaning liquid in a high-pressure state is injected into the interior of the transition tube 104.

[0053] Furthermore, the end of the nozzle 202d cooperates with the mounting plate 103, and can drive the mounting plate 103 to retract onto the mounting cover 101; when the nozzle 202c is spraying the fluorescent liquid, the nozzle 202c extends and retracts, and the bottom of the nozzle 202d at its end will not contact the mounting plate 103. When all the welds are sprayed with the fluorescent liquid, the nozzle 202c is retracted and the bottom of the nozzle 202d is driven to contact the mounting plate 103 to squeeze the mounting plate 103, so that it shrinks onto the mounting cover 101.

[0054] When the mounting plate 103 is retracted onto the mounting cover 101, the mounting plate 103 will drive the support tube 201c to squeeze the annular cover 201a, so that the spring 201f-2 is squeezed, and the arc ring is staggered with the through groove 201b, and the annular cover 201a moves to communicate with the through groove 201b. At this time, the high-pressure cleaning liquid inside the transition cylinder 104 can be quickly ejected from the nozzle 1 202d under the squeezing of the spring 1 201e-1 and the piston ring 201e-2, so as to flush the fluorescent liquid at the weld, which can increase the impact force of flushing, and when the mounting plate 103 is retracted, it will drive the nozzle 2 201d away from the weld, which can further increase the distance between the nozzle 201d and the weld, and further increase the flushing range of the nozzle 201d.

[0055] When the mounting plate 103 is retracted onto the mounting cover 101, the driving motor 203a and the gear 203c are driven to move, and the gear 203c slides along the tooth groove of the gear ring 203b, and the gear 203c and the gear ring 203b remain in meshing state.

[0056] The remaining structure is the same as that of Example 2.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
