[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 This utility model provides a technical solution: a size screening device for composite insulators, comprising: a device housing 1, a screening structure 2, and a fixing structure 3. The device housing 1 is used to protect the screening structure 2 and the fixing structure 3. The screening structure 2 and the fixing structure 3 are disposed in the device housing 1. The screening structure 2 is used to photograph and screen the insulators. The screening structure is displayed through a control panel 13. The fixing structure 3 is used to clamp and fix the insulators to ensure that there is no possibility of tilting or skewing when the screening structure 2 photographs and screens them. The screening structure 2 photographs and screens the insulators to determine their size.

[0027] The screening structure 2 also includes a connecting platform 21 and a camera 22. The connecting platform 21 is located inside the device housing 1. The connecting platform 21 is triangular in shape, which allows the camera 22 to be better positioned to take pictures of the insulator. There are eight cameras 22 in total. The detection results of the cameras 22 are inconsistent because the size and model of each feed port 12 are different. Therefore, the pictures taken by the cameras 22 for screening are also inconsistent. Each group corresponds to one feed port 12, thereby ensuring that targeted detection can be carried out. There are four groups of cameras 22. The cameras 22 are located outside the connecting platform 21. The screening structure 2 has at least two groups, which are arranged in a vertical mirror image on one side of the device housing 1.

[0028] The fixed structure 3 includes a connecting seat 31, an inner plate 32 on the connecting seat 31, a base 35 and a top cover 313 on the inner side of the inner plate 32, and a motor 312 on the connecting seat 31. The connecting seat 31 is fixedly connected to the inner top of the device housing 1 for better connection of the inner plate 32. The motor 312 controls the base 35 to move up and down. The motor 312 is a linear rotary motor that can rotate and push the motor rotating rod forward. When the motor rotating rod moves forward, it is inserted into the insertion hole 311 to drive the transmission shaft 310 and gear 39 to rotate. The gear 39 drives the sawtooth strip 37 to move up and down, thereby driving the base 35 to move up and down to match the height of the insulator. This clamps the insulator from the top and bottom to prevent it from tilting or tilting when the camera 22 takes pictures, which could lead to errors in the rotation of the image. The top cover 313 clamps and fixes the insulator. This clamping device can be adjusted according to the height of the insulator, and its adaptability is more practical than other devices.

[0029] The built-in plate 32 is provided with a sliding groove 33, which allows the base 35 to move up and down more effectively. The base 35 is provided with a snap-fit ​​plate 34, the width of which matches the width of the inner side of the sliding groove 33. The snap-fit ​​plate 34 can slide freely within the sliding groove 33, thus enabling the base 35 to slide within the built-in plate 32. This allows for adaptation to the height of the insulator. The snap-fit ​​plate 34 snaps into the sliding groove 33. The base 35 is provided with a support plate 36, which supports the insertion limiting rod 38 and the serrated strip 37. The support plate 36 is also provided with the serrated strip 37 and the insertion limiting rod 38. The serrated strip 37 is adapted to the gear 39. When the gear 39 rotates, it drives the serrated strip 37 to move up and down, thereby causing the base 35 to move synchronously. The top cover 313 has a limiting hole, the size of which matches the size of the insertion limiting rod 38. When the top cover 313 is in the open state... The insertion limit rod 38 will abut against the top cover 313 to prevent the top cover 313 from sealing tightly. The top cover 313 is connected to the inner plate 32 via a rotating shaft. The top cover 313 can rotate via the rotating shaft. When the base 35 is affected by the downward pressure of the insulator, it will drive the insertion limit rod 38 to move downward. When the top cover 313 is not abutting against the insertion limit rod 38, it will close naturally. At this time, the motor 312 is inserted into the insertion hole 311 to drive the transmission shaft 310 and the gear 39. The gear 39 rotates, driving the transmission shaft 310 to rotate clockwise, thereby causing the sawtooth rack 37 and the base 35 to move upward. The base 35 drives the insertion limiting rod 38 to move upward and insert into the insertion hole of the top cover 313, and limits the top cover 313 to prevent it from flipping open due to the constant pressure of the insulator, thereby squeezing the insulator from top to bottom and fixing the insulator. The insertion limiting rod 38 is used to limit or insert and fix the top cover 313.

[0030] The built-in plate 32 is equipped with a drive shaft 310. The drive shaft 310 is used to drive the gear 39 to rotate under the drive of the motor 312, thereby driving the base 35 to move up and down. The output end of the drive shaft 310 is equipped with a gear 39, which meshes with the sawtooth rack 37. The input end of the drive shaft 310 is provided with a plug hole 311. The plug hole 311 is used to ensure that the motor rotation rod of the motor 312 can drive the drive shaft 310 to rotate. The plug hole 311 is driven to rotate by the motor 312, and the gear 39 and the sawtooth rack 37 mesh, driving the base 35 to move up and down.

[0031] The outer casing 1 of the device is also provided with a feeding hopper 11, a control panel 13, and a material retrieval door 14. The feeding hopper 11 is located on the top of the outer casing 1 and provides protection for the feeding port 12 to prevent other foreign objects from accidentally falling into the feeding port 12. The inner side of the feeding port 12 penetrates the outer casing 1 and is used to place insulators on the base 35 in the outer casing 1. The control panel 13 is located on the side of the outer casing 1 and is used to control the entire device. The material retrieval door 14 is located on the outer casing 1 and is divided into two sections that can be opened horizontally to retrieve the tested insulators. There are at least four feeding ports 12, which are used to place insulators of different models and sizes in the outer casing 1 to improve the adaptability of the device. The insulators are of different sizes and are arranged in a horizontal row on the top of the feeding ports 12.

[0032] When using the composite insulator size screening device, firstly, insulators of different models and sizes are placed below the feed hopper 11, and then fed into the device housing 1 through the feed port 12 inside the feed hopper 11. The insulators fall onto the base 35, and due to their own weight, the base 35 is subjected to downward pressure. The snap-fit ​​plate 34 on the base 35 slides downward in the slide groove 33, causing the insertion limiting rod 38 to move downward. At this time, the top cover 313 closes naturally without the insertion limiting rod 38 pressing against it. Next, the motor 312 starts working, and the motor rotating rod is inserted into the insertion hole 311, driving the transmission shaft 310 and gear 39 to rotate. The gear 39 meshes with the sawtooth rack 37, causing the sawtooth rack 37 to move upward, thereby moving the base 35 upward. As the base 35 moves upward, it also drives the insertion limiting rod 38 upward. When the insertion limiting rod 38 is inserted into the insertion hole of the top cover 313, it limits the top cover 313, preventing it from flipping open due to the pressure of the insulator. In this way, the base 35 and the top cover 313 press and fix the insulator from above and below. Then, the screening structure 2 in the device housing 1 starts to work, and four sets of cameras 22 take pictures of the insulators for screening. Each set of cameras 22 corresponds to a feeding port 12 to ensure targeted testing. Since the detection results of two cameras 22 in a group are inconsistent, and the size and model of each feeding port 12 are also different, the image taken by the cameras 22 will be different when screening different insulators. The screening results will be displayed on the control panel 13. Finally, after screening is completed, the material removal door 14 is opened. The material removal door 14 is divided into two parts and can be opened horizontally to remove the tested insulators from the device housing 1.
