[0002] During PCCP pipeline construction, after the pipes are butt-jointed, polysulfide sealant is applied to the joints. However, this construction process presented several drawbacks, primarily: the circular cross-section of the pipes meant that during inspection, only the left and right sides and the top of the pipe could be inspected for coating quality. Furthermore, the bottom of the pipe, buried in the corner of the sand cushion, was difficult to inspect. This not only impacted the inspection schedule but also severely affected construction quality, creating potential quality risks for the project. Utility Model Content

[0021] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation methods of the present invention are now described in detail with reference to the accompanying drawings.

[0022] like Figure 1-6 As shown, the device for checking the quality of pipe interface sealant coating includes a telescopic rod 1, a fixing frame 2 connected to the front end of the telescopic rod 1 and capable of adjusting the axial angle with the telescopic rod 1, and an adjustable reflector 3 connected to the fixing frame 2.

[0023] The device for inspecting the quality of sealant coating on pipe interfaces is provided with a fixing frame 2 at the front end of a telescopic rod 1, and an angle-adjustable reflector 3 is provided on the fixing frame 2. The length of the telescopic rod 1 is adjusted to adapt to detections of different depths. At the same time, the applicability of the device is improved by adjusting the angle of the adjustable reflector 3 and rotating the telescopic rod 1 in some narrow locations. The device of the utility model effectively improves the acceptance efficiency, can timely discover quality hazards in construction, improves the quality of sealant construction, and has a simple structure and low cost.

[0024] The telescopic rod 1 is made of a stainless steel tube and has a length of 150 cm. A connecting seat is provided at the front end of the telescopic rod 1. The fixing frame 2 is connected to the hinge seat by bolts and is tightened by the bolts to achieve angle adjustment or fixation.

[0025] The adjustable reflector 3 includes a reflector body, a support 4 arranged on the back of the reflector body and an arm 8 connected to the support 4. A hinge shaft 5 is provided at the lower end of the arm 8. A connecting hole adapted to the hinge shaft 5 is provided on the fixing frame 2. The hinge shaft 5 is passed through the connecting hole. The hinge shaft 5 is preferably a damping shaft.

[0026] The side wall of the support 4 is provided with a waist hole 9, and the upper end of the support arm 8 is connected to the waist hole 9 and can be fixed in a position within the waist hole 9. The waist hole 9 can be used to adjust the position of the reflector body to better adapt to inspection requirements. In this embodiment, the connection at the waist hole 9 can be combined with a bolt and a nut. The bolt passes through the waist hole 9 and the nut is tightened from the outside to achieve the purpose of pressing the support arm 8 against the support 4 to achieve the purpose of positioning.

[0027] Taking into account the weather and environment during inspection, dim light is not conducive to inspection, and a lighting assembly is also provided on the fixed frame 2. The lighting assembly includes a lamp tube 6 rotatably connected to the fixed frame 2. Lamp beads are provided in the lamp tube 6 for emitting light along the side wall of the lamp tube 6. A switch 7 for controlling the light emission of the lamp beads is provided on the upper part of the lamp tube 6.
