DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-6 , the utility model provides a technical solution:

[0029] Embodiment 1:

[0030] An imaging plate device for DR detection of small-diameter pipelines includes a fixed half circle 1 and a movable half circle 2. The fixed half circle 1 and the movable half circle 2 are relatively rotated by a rotating connection mechanism, so that the device can be quickly installed on the pipeline. At the same time, a quick-release mechanism 3 is provided between the fixed half circle 1 and the movable half circle 2, which is used to lock the two and ensure the stability of the device on the pipeline. The working principle of the quick-release mechanism 3 is similar to the quick-release mechanism 3 of the trunk of a motorcycle. The operator can also select a suitable quick-release device according to actual conditions. Such a mechanism is a device well known to technicians in this field and is a commonly used device in this technical field. It will not be described here. A semi-track ring 5 is provided on both the movable half circle 2 and the fixed half circle 1. The two semi-track rings 5 ​​are matched and used to form a continuous and complete circular track, providing a precise path for the movement of the imaging detection mechanism 6.

[0031] To ensure that the device can be stably fixed on the pipeline, a plurality of positioning mechanisms 4 are fixedly provided on the fixed half circle 1 and the movable half circle 2. In the present embodiment, there are two positioning mechanisms 4 on the fixed half circle 1 and one positioning mechanism 4 on the movable half circle 2. The three positioning mechanisms 4 are arranged in a circular equidistant array. These positioning mechanisms 4 are composed of a spiral coil 401 and a screw rod 402. The spiral coil 401 is firmly provided on the half circle by welding or other fixing methods, while the screw rod 402 can rotate freely in the spiral coil 401. When the device needs to be fixed, the screw rod 402 is rotated to make the pad 4022 on the ball head 4021 at one end thereof closely contact the outer wall of the pipeline, thereby realizing the fastening of the device on pipelines of different diameters. To further increase the contact area and friction with the pipeline, a gasket 4023 with a texture is fixedly provided on the pad 4022. This design not only improves the stability of the device, but also enables it to adapt to pipelines of different surface roughnesses.

[0032] To facilitate the operator to make adjustments, a handle 4025 is fixedly provided at the other end of the screw rod 402 to make manual rotation easier. At the same time, in order to facilitate the use of tools for quick operation, a hexagonal hole 4026 is cleverly opened on the screw rod 402, so that tools such as an hexagonal wrench can be used for more efficient adjustments.

[0033] When in use, the operator adjusts the distance between the screw rods 402 so that the device is coaxial with the pipeline to achieve more accurate measurement.

[0034] Embodiment 2:

[0035] This embodiment further describes the imaging detection mechanism 6 in detail based on the first embodiment.

[0036] The imaging detection mechanism 6 mainly includes a base plate 601 , a roller 602 , a driving motor 603 , a driving wheel 604 , an anti-slip ring 605 , an imaging plate 606 , a support frame 607 and a ray emitter 608 .

[0037] Two rollers 602 are rotatably arranged on the bottom plate 601. The main function of the two rollers 602 is to support the bottom plate 601 so that it can move smoothly on the semi-track ring 5. A driving motor 603 is also arranged on the bottom plate 601. The shaft of the motor passes through the bottom plate 601, and a driving wheel 604 is fixedly arranged on the shaft. In order to ensure stable contact and sufficient friction between the driving wheel 604 and the semi-track ring 5, an anti-slip ring 605 is fixedly arranged on the driving wheel 604.

[0038] When using the device, the operator first starts the ray emitter 608 and other key components to ensure that they are in the best working state. Then, the drive motor 603 is started, and the motor shaft drives the drive wheel 604 to roll on the semi-track ring 5, thereby driving the entire imaging detection mechanism 6 to move along the semi-track ring 5. This movement mode realizes the circumferential scanning of the outer wall of the pipeline, ensuring comprehensive and no-dead-angle detection of the pipeline.

[0039] The two rollers 602 work together with the driving wheel 604 to ensure that the base plate 601 is stably fixed on the semi-track ring 5. An anti-slip ring can also be provided on the roller 602 to prevent the roller 602 from detaching from the semi-track ring 5. An imaging plate 606 is vertically fixed on the base plate 601. This is a key component for receiving rays and emitting image signals. The design and optimization of the imaging plate 606 ensures accurate reception and high-quality conversion of ray signals.

[0040] A support frame 607 is fixedly mounted on the imaging plate 606, and a ray emitter 608 is fixedly mounted on the support frame 607. The ray emitter 608 is arranged on the opposite side of the imaging plate 606, and its precise position and angle ensure that the ray can accurately penetrate the pipe wall, thereby effectively detecting the pipe.

[0041] In order to improve the heat dissipation performance of the imaging board 606 and ensure its stability and reliability for long-term operation, a support rib 609 is fixedly provided on the back side of the imaging board 606, and a heat dissipation fan 610 is fixedly provided on the support rib 609. This design cleverly utilizes the air flow principle to quickly discharge the heat generated by the imaging board 606, thereby ensuring the normal operation of the imaging board 606. The efficient operation of the heat dissipation fan 610 not only extends the service life of the imaging board 606, but also ensures the accuracy and reliability of the detection results.

[0042] Working principle: During the use of the utility model, when the imaging plate 606 device is used for pipeline DR detection, the fixed half circle 1 and the movable half circle 2 are firstly sleeved on the pipeline, and then the screw 402 is rotated to make the ball head 4021 press against the inner wall of the pipeline to fix the device on the pipeline. At this time, the design of the pad 4022 and the gasket 4023 can increase the contact area between the ball head 4021 and the inner wall of the pipeline, and improve the stability of the fixation;

[0043] Next, the driving motor 603 is started to move the bottom plate 601 on the semi-track ring 5. At the same time, the ray emitter 608 emits rays to detect the pipeline. After passing through the pipeline, these rays are received by the imaging plate 606 and converted into image signals. These image signals can be further processed and analyzed to obtain detailed information inside the pipeline.

[0044] During the entire detection process, the quick-release mechanism 3 ensures the stability of the fixed half circle 1 and the movable half circle 2, and the cooling fan 610 on the imaging board 606 effectively solves the heat dissipation problem. In addition, the number of positioning mechanisms 4 is at least three, and they are arranged in a circular equidistant array, which further improves the stability and reliability of the device.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
