[0019] Embodiment 1

[0020] A pipeline inspection device, such as Figure 1 As shown, the device includes a square fixing plate 1 arranged horizontally. A fixing component 3 for fixing the main pipeline 2 is fixedly mounted on the upper surface of the fixing plate 1. An inspection plate 4, which is arranged vertically and can simultaneously hold the ends of multiple branch pipelines 5 at different heights, is fixedly mounted on one side of the fixing plate 1. The fixing component 3 is an upright cylinder with a placement hole on its upper surface for placing the main pipeline 2. The diameter of the placement hole matches the diameter of the main pipeline 2. By placing the cylindrical main pipeline 2 into the fixing component 3, the main pipeline 2 can be placed upright on the upper surface of the fixing plate 1.

[0021] Since it is necessary to inspect the positions of the ends of branch pipes 5 at four different heights, with the heights of the ends of the leftmost, third from left to right, fourth from left to right, and second from left to right decreasing sequentially, the upper side of the inspection plate 4 is stepped. The height of the steps corresponds to the height of the ends of the branch pipes 5, allowing the ends of multiple branch pipes 5 to be placed simultaneously on the upper surface of the inspection plate 4 at different heights. In this embodiment, the horizontal distance between the ends of the second and third branch pipes 5 from left to right is relatively close, but the vertical distance is relatively large, making it inconvenient to set up continuous steps to inspect the positions of the ends of the branch pipes 5. Therefore, the middle of the inspection plate 4 has a horizontal notch extending into the interior of the inspection plate 4 along the right sidewall of the inspection plate 4, with the lower part of the horizontal notch corresponding to the height of the third branch pipe 5 from left to right.

[0022] At least two positioning components 6 for inspecting the position of the branch pipe 5 are fixedly installed on one side of the inspection plate 4. In this embodiment, the positioning components 6 are all located on the top edge of the inspection plate 4. Since four different heights of branch pipes 5 need to be inspected, there are four positioning components 6. They are all grooves that open on the side of the inspection plate 4 near the fixed component. The shape of the groove sidewall is adapted to the shape of the branch pipe 5 end, and the position of the groove corresponds to the position of the branch pipe 5 end. Specifically, the shape of the groove sidewall is a cylindrical surface, and the extension direction of the groove is parallel to the thickness direction of the inspection plate 4, so that it can be adapted to the cylindrical branch pipe 5 end, thereby placing the branch pipe 5 end in the groove. At the same time, the length of the groove is less than the thickness of the inspection plate 4, which makes it easier for the branch pipe 5 end to abut against the sidewall of the groove away from the fixed plate 1, which can further restrict the position of the branch pipe 5 in the groove.

[0023] The main pipe 2 and the end of the branch pipe 5 of the standard air conditioner branch are placed in the fixed part 3 and the positioning part 6 of the standard mold, respectively. If the end of the branch pipe 5 can be placed in the groove and abut against the side wall of the groove away from the fixed plate 1, it is considered that the air conditioner branch to be inspected is the same as the standard air conditioner branch. If the end of the branch pipe 5 cannot completely fit the side wall of the groove or cannot abut against the side wall of the groove away from the fixed plate 1, it is considered that there is a difference between the air conditioner branch and the standard product.

[0024] By placing the ends of the branch pipes 5 in different grooves on the top edge of the inspection plate 4 in the standard mold, respectively, and observing the fit degree of the ends of the branch pipes 5 of the air conditioner branch to be inspected and the side wall of the groove, it can be determined whether the positions of the ends of the branch pipes 5 of the same batch of air conditioner branches are the same as those of the standard air conditioner branch. The positions of the ends of the branch pipes 5 of the special-shaped air conditioner branch with multiple branch pipes and three-dimensional shape can be accurately inspected.

[0025] When the embodiment is used, as shown in Figure 2 , first, the main pipe 2 is placed in the hollow cylinder, and the branch pipe 5 is placed in the groove. By observing the fit degree of the end of the branch pipe 5 and the side wall of the groove, it can be quickly determined whether the batch of air conditioner branches meets the requirements, thereby speeding up the inspection and improving the inspection efficiency.

[0026] Embodiment 2

[0027] A pipe inspection device, as shown in Figure 3 , based on embodiment 1, the positions of the ends of the branch pipes 5 with four different heights also need to be inspected. The heights of the ends of the branch pipes 5 from left to right are successively reduced, so the top edge of the inspection plate 4 has four different heights, each of which is the same as the height of the end of the branch pipe 5. The ends of the branch pipes 5 with different heights can be placed in grooves with different heights, thereby meeting the actual needs.
