Description

Technical Field

[0001] This utility model belongs to the technical field of protective clothing testing devices, and in particular relates to an automatic testing device for the compliance of nuclear power protective clothing wearing. Background Technology

[0002] In the nuclear power industry, potential risks such as radioactive material leaks and high temperatures and pressures constantly threaten the lives of workers. Nuclear power protective clothing, as a crucial barrier against these risks, is highly dependent on proper wearing procedures, such as sealed seams, correctly fitted components, and closed openings. These compliances directly determine the effectiveness of the protective measures and are a core element in ensuring worker safety and preventing nuclear accidents.

[0003] Traditional manual verification methods involve dedicated testing personnel checking the wearing standards of protective clothing, hats, masks, gloves, and boots one by one through visual observation and manual touch, as well as the closure status of collars, cuffs, trouser legs, zippers, and the sealing of seams.

[0004] Manual verification has inherent blind spots. Due to the limitations of personnel's body posture and observation angle, it is difficult for inspectors to fully reach and carefully inspect these blind spots. These blind spots often become potential channels for the infiltration of radioactive materials, but they cannot be effectively verified through manual operation. The efficiency of the inspection process is low. Each operator must show their head, torso, limbs and other parts to the inspector one by one, and cooperate to complete actions such as checking the wearing of gloves and confirming the zipper closure. If problems are found during the process, adjustments and re-verification are required repeatedly, resulting in a long inspection time for a single person.

[0005] To address this issue, we provide an automatic detection device for compliance of nuclear power plant protective clothing, which solves the aforementioned problems. Utility Model Content

[0006] The purpose of this utility model is to provide an automatic detection device for compliance of nuclear power protective clothing. Through the cooperation of the lifting and adjusting mechanism, the detection mechanism and the scanning component, it solves the problem that the detection method in the prior art is limited by the body posture and observation angle of the personnel, making it difficult for the inspectors to fully touch and carefully inspect, and the inspection efficiency is relatively low.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0008] This utility model relates to an automatic detection device for compliance of nuclear power plant protective clothing, comprising a base plate, a lifting and adjusting mechanism fixedly connected to the rear end of the top of the base plate, a detection mechanism fixedly connected to the top of the lifting and adjusting mechanism, and a scanning assembly fixedly connected to the surface of the lifting and adjusting mechanism. The scanning assembly includes a scanning frame, one side of which is fixedly connected to the lifting and adjusting mechanism, and two fixed plates fixedly connected to both sides of the scanning frame. A cylinder is fixedly connected to one side of each fixed plate, a mounting base is fixedly connected to one side of each cylinder, and a scanning head is fixedly connected to one side of each mounting base. An adjustable... The gimbal mechanism integrates a signal transmitting and receiving module inside the scanning head. During the detection process, the scanning head moves horizontally along the side of the protective suit under the drive of a cylinder. When the operator stands in front of the device, the cylinder pushes the mounting base to move the scanning head laterally toward the protective suit, reciprocating in the process. At the same time, the height is adjusted by the lifting and adjusting mechanism. The scanning head emits detection signals to the corresponding parts of the protective suit. After the signal contacts the surface of the protective suit, it forms a feedback signal. The scanning head receives the feedback signal and analyzes the characteristics of the feedback signal to determine whether there are any non-compliant conditions such as gaps or unclosed openings in the corresponding parts of the protective suit.

[0009] The present invention is further configured such that the adjustable gimbal mechanism includes a rotating platform, the bottom of which is fixedly connected to a scanning frame, and a connecting frame is fixedly connected to the top of the rotating platform. A first motor is fixedly connected to one side of the connecting frame, and a first camera is fixedly connected to the output end of the first motor. The rotating platform drives the connecting frame and the first camera to rotate around a vertical axis, which can cover the detection needs of different directions of the protective clothing, avoiding blind spots caused by the fixed angle of the camera. The first motor drives the first camera to rotate around a horizontal axis, realizing the adjustment of the up and down angle of the camera. Whether it is the fine fit of the collar of the protective clothing or the connection between the boot and the trouser leg, the first camera can be aligned with the detection target by adjustment, clearly capturing the image details of the key parts.

[0010] The present invention is further configured such that the lifting and adjusting mechanism includes a housing, the bottom of the housing is fixedly connected to a base plate, a second motor is fixedly connected to the top of the inner cavity of the housing, a lead screw is fixedly connected to the output end of the second motor, a movable seat is threadedly connected to the surface of the lead screw, one side of the movable seat is fixedly connected to the scanning frame, the second motor drives the lead screw to rotate, and through the threaded engagement between the lead screw and the movable seat, the rotational motion of the second motor is converted into the linear lifting and lowering motion of the movable seat, thereby achieving highly automated control.

[0011] The present invention is further configured such that the detection mechanism includes a movable seat, the bottom of which is fixedly connected to the outer shell, and a first adjusting rod is provided on the top of the movable seat. A second adjusting rod is movably connected to one side of the first adjusting rod via a pivot, and a second camera is movably connected to the bottom of the second adjusting rod via a pivot. The first adjusting rod and the second adjusting rod are movably connected via a pivot to achieve multi-angle bending, and the spatial position of the second camera can be adjusted according to the detection requirements. The bottom of the second adjusting rod is connected to the second camera via a pivot, which can further fine-tune the shooting angle of the camera to ensure clear capture of the detailed features of the detection part.

[0012] The present invention is further configured such that sliding grooves are provided on both sides of the outer shell, and both sides of the movable seat extend to the outside of the sliding grooves. When the movable seat is raised and lowered under the drive of the lead screw, the sliding grooves restrict the movement trajectory of the movable seat and prevent the movable seat from deviating due to the deviation of the lead screw transmission.

[0013] The present invention is further configured such that a sliding rod is fixedly connected to the bottom of the inner cavity of the outer shell, and a slider is fixedly connected to one side of the movable seat. The slider is slidably connected to the sliding rod and moves up and down synchronously with the movable seat to form auxiliary support for the movable seat and disperse the force of the movable seat on the lead screw.

[0014] The present invention is further configured such that limit grooves are provided on both sides of the fixing plate, and one side of the mounting seat is slidably connected to the limit groove. When the cylinder drives the mounting seat to move the scanning head horizontally, the limit groove restricts the movement direction of the mounting seat, ensuring that the mounting seat always moves smoothly in the horizontal direction.

[0015] The present invention is further configured such that an alarm is fixedly connected to the top of the outer shell surface. The alarm is an audible and visual alarm. When the device detects that the protective clothing is not worn in compliance with regulations, the audible and visual alarm will emit both sound and light warnings. The sound warning can quickly attract the attention of the workers and on-site managers.

[0016] The present invention has the following beneficial effects.

[0017] 1. This utility model uses an automated lifting and adjusting mechanism to quickly adjust the detection height according to the height of the operator, eliminating the need for manual operation and reducing the time spent on height adaptation. The cylinder drives the scanning head to move laterally, and the adjustable gimbal mechanism drives the camera to rotate at multiple angles, simultaneously scanning and acquiring images of key parts such as seams and openings on the front, back, left, and right sides of the protective clothing. This eliminates the need for operators to repeatedly adjust their posture, making it suitable for batch detection scenarios when large-scale operators change shifts, and avoiding delays in starting operations.

[0018] 2. This utility model, through the cooperation of the first adjusting rod, the second adjusting rod and the second camera, can cover the protective hat and collar. The two sets of cameras and the scanning head form a dual verification of vision and scanning, effectively identifying hidden dangers such as minor gaps and insufficient fit, reducing missed detections and providing more reliable protection for the safety of workers.

Detailed Implementation

[0027] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Please see Figure 1-6This utility model is an automatic detection device for compliance of nuclear power protective clothing wearing, including a base plate 1. A lifting and adjusting mechanism 2 is fixedly connected to the rear end of the top of the base plate 1. A detection mechanism 3 is fixedly connected to the top of the lifting and adjusting mechanism 2. A scanning component 4 is fixedly connected to the surface of the lifting and adjusting mechanism 2. The scanning component 4 includes a scanning frame 41. One side of the scanning frame 41 is fixedly connected to the lifting and adjusting mechanism 2. Fixing plates 42 are fixedly connected to both sides of the scanning frame 41. A cylinder 43 is fixedly connected to one side of the fixing plate 42. A mounting base 44 is fixedly connected to one side of the cylinder 43. A scanning head 45 is fixedly connected to one side of the mounting base 44. An adjustable gimbal mechanism 46 is fixedly connected to the top of the scanning frame 41.

[0029] Specifically: The scanning head 45 integrates a signal transmitting and receiving module. During the detection process, the scanning head 45 moves horizontally to the side of the protective suit under the drive of the cylinder 43. When the operator stands in front of the device, the cylinder 43 pushes the mounting base 44 to move the scanning head 45 laterally toward the protective suit, reciprocating in this process. The cylinder 43 is model MGPM20-75Z. At the same time, the height is adjusted by the lifting adjustment mechanism 2. The scanning head 45 emits a detection signal to the corresponding part of the protective suit. After the signal contacts the surface of the protective suit, a feedback signal is formed. The scanning head 45 receives the feedback signal and, by analyzing the characteristics of the feedback signal, determines whether there are any non-compliant situations such as gaps or unclosed openings in the corresponding part of the protective suit.

[0030] The adjustable gimbal mechanism 46 includes a rotating stage 461, the bottom of which is fixedly connected to the scanning frame 41, and a connecting frame 462 fixedly connected to the top of the rotating stage 461. A first motor 463 is fixedly connected to one side of the connecting frame 462, and a first camera 464 is fixedly connected to the output end of the first motor 463. The lifting adjustment mechanism 2 includes a housing 21, the bottom of which is fixedly connected to the base plate 1, and a second motor 22 fixedly connected to the top of the inner cavity of the housing 21. A lead screw 23 is fixedly connected to the output end of the second motor 22, and a movable seat 24 is threaded onto the surface of the lead screw 23. One side of the movable seat 24 is fixedly connected to the scanning frame 41. The detection mechanism 3 includes a movable seat 31. The bottom is fixedly connected to the outer shell 21. The top of the movable seat 31 is provided with a first adjusting rod 32. One side of the first adjusting rod 32 is movably connected to a second adjusting rod 33 via a pivot. The bottom of the second adjusting rod 33 is movably connected to a second camera 34 via a pivot. Both sides of the outer shell 21 are provided with sliding grooves 5. Both sides of the movable seat 24 extend to the outside of the sliding grooves 5. The bottom of the inner cavity of the outer shell 21 is fixedly connected with a sliding rod 6. One side of the movable seat 24 is fixedly connected with a slider 7. The slider 7 is slidably connected to the sliding rod 6. Both sides of the fixed plate 42 are provided with limit grooves 8. One side of the mounting seat 44 is slidably connected to the limit groove 8. The top of the surface of the outer shell 21 is fixedly connected with an alarm 9, which is an audible and visual alarm.

[0031] Specifically: The rotary table 461 drives the connecting frame 462 and the first camera 464 to rotate around the vertical axis, which can cover the detection needs of the protective clothing from different directions, avoiding blind spots caused by the fixed camera angle. The first motor 463 drives the first camera 464 to rotate around the horizontal axis, realizing the adjustment of the camera's vertical angle. Whether it is the fine fit of the protective clothing collar or the connection between the boot and the trouser leg, the first camera 464 can be aligned with the detection target by adjustment, clearly capturing the image details of key parts. The second motor 22 drives the lead screw 23 to rotate. Through the threaded engagement between the lead screw 23 and the moving seat 24, the rotational motion of the second motor 22 is converted into the linear lifting motion of the moving seat 24, realizing a high degree of automated control. The first adjusting rod 32 and the second adjusting rod 33 are movably connected by a rotating shaft, realizing multi-angle bending and adjusting the second camera according to the detection needs. The spatial position of the head 34, the bottom of the second adjusting rod 33 and the second camera 34 are connected by a rotating shaft, which can further fine adjust the shooting angle of the camera to ensure clear capture of the detailed features of the detection part. When the moving seat 24 is raised and lowered under the drive of the lead screw 23, the slide groove 5 restricts the movement trajectory of the moving seat 24 to prevent the moving seat 24 from deviating due to the transmission deviation of the lead screw 23. The slider 7 is slidably connected to the slide rod 6 and rises and falls synchronously with the moving seat 24 to form auxiliary support for the moving seat 24 and disperse the force of the moving seat 24 on the lead screw 23. When the cylinder 43 drives the mounting seat 44 to move the scanning head 45 horizontally, the limiting groove 8 restricts the movement direction of the mounting seat 44 to ensure that the mounting seat 44 always moves smoothly in the horizontal direction. When the device detects that the protective clothing is not worn in compliance with regulations, the alarm 9 will emit an audible warning and a light warning at the same time. The audible warning can quickly attract the attention of the operators and on-site managers.

[0032] The working principle of this utility model is as follows: After the operator puts on the nuclear power protective suit, he stands on the base plate 1. The cylinder 43 drives the mounting base 44 to move laterally. The second motor 22 is model 57BYG250S-007A. The second motor 22 drives the lead screw 23 to rotate. Through the threaded engagement between the lead screw 23 and the moving base 24, the rotational motion is converted into the vertical lifting motion of the moving base 24, which in turn drives the scanning frame 41 and the scanning head 45 to move up and down synchronously. This allows the scanning head 45 to fully cover all the key side parts of the protective suit from the shoulders and torso to the legs, avoiding missed detection of some areas due to a fixed height. The signal transmission module inside the scanning head 45 transmits detection signals to the corresponding parts of the protective suit. After the signal contacts the surface of the protective suit, a feedback signal is formed. The signal receiving module receives the signal in real time. If there is a gap or an unclosed opening in a certain part of the protective suit, the feedback signal will be interrupted or fluctuate abnormally. The scanning head 45 transmits the signal characteristics to the background processing unit to make a preliminary judgment on the compliance of the part.

[0033] While the scanning component 4 is performing the detection, the rotary table 461 drives the connecting frame 462 and the first camera 464 to rotate around the vertical axis, covering different positions of the protective clothing from front to back and left to right. The lifting and adjusting mechanism 2 moves up and down synchronously, causing the first camera 464 to rise and fall together with the scanning frame 41, so that the first camera 464 can follow the change of the detection position and capture image details of various parts of the protective clothing from top to bottom. Through the dynamic height adjustment of the lifting and adjusting mechanism 2, in conjunction with the first motor 463 driving the first camera 464 to fine-tune the angle around the horizontal axis, image data of the detection parts at different heights are clearly obtained, which complements the feedback signal of the scanning head 45 to further improve the accuracy of the judgment. The first motor 463 is a 42BYGH48-1684A stepper motor.

[0034] The first adjusting rod 32 can be manually adjusted so that the first adjusting rod 32 and the second adjusting rod 33 can be bent at multiple angles around the pivot. The pivot at the bottom of the second adjusting rod 33 drives the second camera 34 to finely adjust the angle, ensuring clear capture of the sealing status of the underarm seam, improving the detection data, and avoiding missed detection of hidden parts.

[0035] If all tested areas meet the standards, the device remains silent and indicates to the operator that the test has passed. If any non-compliance is found, such as gaps or unclosed openings, the alarm 9 on the top of the casing 21 will be activated immediately, emitting both audible and visual warnings. The model of the alarm 9 is TGSG-07.

The preferred embodiments do not describe all the details in detail, nor do they limit the present utility model to the specific implementation methods described.
