[0038] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0039] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0040] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0041] In the description of the embodiments of this utility model, it should be noted that if terms such as "upper," "lower," "horizontal," or "inner" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use, they are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the utility model. Furthermore, terms such as "first" and "second" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0042] Furthermore, the use of the term "horizontal" does not imply that the component must be absolutely horizontal, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0043] High-voltage or ultra-high-voltage switch products are key components in power systems. The installation quality of the hydraulic mechanism connecting pipe seals directly affects the accuracy and stability of the high-voltage switch operation. Incorrect installation of the seals and support rings can lead to insufficient pressure and pressure loss in the high-voltage switch, causing it to lose its effectiveness.

[0044] Currently, due to the variety and complexity of the connecting pipes in the hydraulic mechanism of high-voltage switches, manufacturers use manual installation of support rings and sealing rings. Moreover, due to factors such as eye fatigue, manual installation of support rings and sealing rings may be incorrect, which may pose a hidden danger to the operation of highly reliable power systems.

[0045] An existing technology provides a bearing seal ring error prevention inspection device (CN214120973U), including a platform, a dial indicator, and a first inspection block and a second inspection block arranged opposite to each other. The first and second inspection blocks are fixedly mounted on the platform. On the inner end faces of both the first and second inspection blocks, there are inspection grooves and inspection protrusions corresponding to the positions of two seal ring mounting slots on the outer ring of the bearing. The inspection grooves are used to mate with the seal rings on the outer ring of the bearing, and the inspection protrusions are used to mate with one of the seal ring mounting slots on the outer ring of the bearing. The dial indicator is horizontally fixed on the outer end face of the first inspection block, with the measuring rod of the dial indicator passing through the first inspection block and the measuring head extending out of the inspection groove. The advantages are that it can quickly inspect whether the seal rings on the outer ring of the bearing are missing or excessive, with high efficiency. Furthermore, due to the presence of a position adjustment mechanism, the distance between the first and second inspection blocks is adjustable, thus it can be used to inspect bearings of different specifications, exhibiting good versatility.

[0046] However, when the above-mentioned patented technology is applied, it is necessary to manually inspect each individual product of different types, which results in low inspection efficiency; in addition, during the inspection process, the positions of the two inspection blocks need to be manually adjusted, making it impossible to achieve automatic inspection of different products.

[0047] In order to overcome the above-mentioned technical defects, the inventors have provided an automatic detection system for the installation of sealing rings on the connecting pipes of high-pressure switch hydraulic mechanisms.

[0048] The present invention will now be described in further detail with reference to the accompanying drawings:

[0049] like Figures 1-3As shown in the embodiment of this utility model, an automatic detection system for the installation of sealing rings on the connecting pipes of a high-pressure switch hydraulic mechanism is provided. The system includes a body 1, which has an L-shaped structure. The body 1 is equipped with a placement tray 2, an industrial control integrated computer 4, and an image acquisition device 5. The placement tray 2 is located at the shorter end of the body 1, while the industrial control integrated computer 4 and the image acquisition device 5 are located at the longer end of the body 1. The placement tray 2 and the image acquisition device 5 are axially perpendicular, as are the industrial control integrated computer 4 and the image acquisition device 5. The end of the body 1 with the placement tray 2 has a tray placement platform 3, with the placement tray 2 located on top of the tray placement platform 3. The industrial control integrated computer 4 is electrically connected to the placement tray 2 and the image acquisition device 5. The placement tray 2 includes a placement component and a drive component, which are connected to the placement component. The placement component carries the connecting pipe, and the drive component drives the placement component to rotate the connecting pipe, allowing the image acquisition device 5 to acquire images of the sealing ring 205 on the connecting pipe. By connecting the placement component and the drive component, connecting pipes of different specifications can be placed on top of the placement component. When inspecting the sealing rings 205 on these pipes, the drive component rotates multiple connecting pipes synchronously to detect whether a sealing ring 205 is installed, thus achieving synchronous inspection of different types of connecting pipes. Simultaneously, the installation of the drive component automates the entire inspection process. During inspection, the system uses an industrial control computer 4 and an image acquisition device 5 for automated inspection, eliminating the need for manual intervention and significantly improving efficiency. Furthermore, the image acquisition device 5 accurately captures images of the sealing rings 205 on the connecting pipes, providing a high-quality data foundation for subsequent image processing and analysis, thereby improving inspection accuracy. Compared to traditional inspection methods, automation significantly reduces labor costs, minimizes errors caused by human factors such as visual fatigue and misjudgment, and improves the reliability of inspection results. Figure 3As shown, the placement assembly includes a placement frame 201, within which multiple sets of rotating rods 202 are arranged at intervals, and a connecting tube is placed on each set of rotating rods 202. The drive assembly includes a drive unit and a drive shaft. One end of the drive shaft is connected to the drive unit, and the other end extends into the placement frame 201 and is fitted with a drive belt 203. Multiple drive belts 203 are provided, and each set of rotating rods 202 is connected to the other via the drive belts 203. The multiple sets of rotating rods 202 arranged at intervals within the placement frame 201 ensure that the connecting tubes can be placed independently and stably, avoiding mutual interference between the connecting tubes and making the testing process smoother. The drive unit's power is transmitted to each set of rotating rods 202 via the drive belts 203, achieving synchronous rotation of the connecting tubes. The drive belts 203 have good flexibility and wear resistance, ensuring the stability and durability of power transmission. Furthermore, since each set of rotating rods 202 is spaced apart and connected by a transmission belt 203, the spacing of the rotating rods 202 can be adjusted according to different specifications of connecting pipes, enabling the system to adapt to the detection of connecting pipes of various sizes, thus enhancing the system's versatility and adaptability. The automated design of the drive assembly allows the connecting pipe to rotate automatically in front of the image acquisition device 5 without manual operation, greatly improving detection efficiency. At the same time, the automated rotation also ensures the comprehensiveness and accuracy of image acquisition.

[0050] like Figure 3As shown, the placement frame 201 has a rectangular structure. Each set of rotating rods 202 is spaced apart along the length of the placement frame 201. One end of each set of rotating rods 202 is rotatably connected to the inner side of one end of the placement frame 201, and the other end is rotatably connected to the inner side of the other end of the placement frame 201. Each set of rotating rods 202 consists of two rods, spaced apart. The rectangular structure of the placement frame 201 maximizes the use of space within the machine body 1, allowing for the placement of more rotating rods 202 and connecting pipes within a limited space, thus improving space utilization. Simultaneously, since the rotating rods 202 are spaced apart along the length of the placement frame 201, the spacing between the rotating rods 202 can be easily adjusted as needed to accommodate connecting pipes of different sizes. This flexibility makes the system easier to maintain and use. During the detection process, the rectangular structure and the longitudinally spaced rotating rods 202 facilitate omnidirectional image acquisition of the connecting pipe by the image acquisition device 5 from a fixed position, reducing obstructions and blind spots during image acquisition and improving the quality and accuracy of image acquisition. Furthermore, the rectangular structure itself possesses high structural strength, capable of resisting the effects of external forces and vibrations, which is crucial for ensuring the accuracy and reliability of the testing process. The rotatable connections at both ends of the rotating rod 202 to the inner side of the placement frame 201 provide stable support for the rotating rod 202, ensuring that it will not wobble or shift due to unstable support during rotation, thus guaranteeing the stability and accuracy of the connecting tube during the testing process. Since each set of rotating rods 202 is rotatably connected to the placement frame 201 at both ends, the distribution of the rotating rods 202 within the placement frame 201 is more uniform, helping to reduce imbalance and vibration during rotation and improving the stability and reliability of the system.

[0051] In one embodiment, the drive unit is a motor 204. The motor 204 is small in size and light in weight, and is easy to integrate with other components, which helps to reduce the size and weight of the entire detection system and improve the portability and flexibility of the system. In another embodiment, the drive unit is a motor. The motor has a relatively simple structure and is easy to maintain and replace. When the motor fails, it can be quickly repaired or replaced to ensure the normal operation of the system.

[0052] like Figure 2As shown, the image acquisition device 5 includes an image acquisition unit 501 and a bar light source 502. The bar light source 502 is positioned on opposite sides of the image acquisition unit 501, with the acquisition end of the image acquisition unit 501 facing the placement tray 2. Specifically, the image acquisition unit 501 is an industrial camera, and the bar light source 502 is tilted and positioned on one side of the image acquisition unit 501. The placement of the bar light source 502 provides a stable and uniform lighting environment for the image acquisition unit 501, reducing image blurring, shadows, or reflections caused by uneven or insufficient lighting, thereby improving the clarity and quality of image acquisition. With the assistance of the bar light source 502, the image acquisition unit 501 can more accurately capture the detailed features of the sealing ring 205 on the connecting pipe, such as edges, cracks, or foreign objects, thereby improving the accuracy and reliability of detection. Furthermore, the design of the bar light source 502 enables the image acquisition device 5 to maintain stable performance under different lighting conditions. Whether in a bright or dim environment, the bar light source 502 can provide sufficient light for the image acquisition unit 501, ensuring that the accuracy of the detection is not affected by the lighting conditions.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit its protection scope. Although the utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that after reading this utility model, they can still make various changes, modifications or equivalent substitutions to the specific implementation of the utility model, but these changes, modifications or equivalent substitutions are all within the protection scope of the pending claims of the utility model.
