Description

Technical Field

[0001] The invention relates to the technical field of chemical detection equipment, and in particular to an anti-corrosion detection device based on chemical conditions. Background Art

[0002] When conducting anti-corrosion inspection on chemical components, one of the most basic means is to check the specific working surface of the chemical components and conduct a comprehensive inspection when necessary. For example, for metal chemical components, the direct criterion for judging whether the surface is corroded is whether the distribution of the metal luster on the surface meets the requirements. Usually, the corroded parts will form obvious abnormalities, which can be identified by the naked eye. However, when inspecting various chemical components, they cannot be taken away from the on-site workshop in many cases, but need to be inspected on the spot, such as the valve cores of various valves, some seals of containers for chemical agents, and other key components involved in various major chemical workshops. If there is an annual inspection, there are many types of chemical components, and the inspection volume of various components is relatively large, the inspection personnel are required to stay in the chemical workshop all the time. Since some chemical workshops generally do not allow operators to stay for a long time, multiple people must work together to inspect during the inspection, so that each person can stay in the chemical workshop for a shorter time, and try to minimize the possible damage to the body and the accidents caused by the long stay of personnel.

[0003] In order to solve the above problems, technicians in this field have sampled the existing visual intelligence technology, using the detection camera to take pictures of chemical components, and the inspection personnel can check the corrosion resistance remotely, but this requires an operator to be retained on site to place the chemical components on the storage board for placing chemical components, and then the detection camera automatically takes pictures, and can even automatically determine whether it is corroded and the degree of corrosion. These are very mature applications in existing robot vision technology. However, although this detection method can minimize the number of people entering and leaving the chemical workshop, it still requires personnel to actively place chemical components, because chemical components are different in type, shape and size. There are certain differences. Manual placement can be placed into the ideal detection field of view of the detection camera faster according to the model of the part, avoiding partial missed detection or the situation that it is difficult to fully display the corrosion surface because it is too far away. Therefore, manual intervention is required to adjust the position of the chemical components as much as possible, especially to ensure that the chemical components can be photographed more clearly by the detection camera at a suitable distance. It can be seen from this that this method of relying solely on manual placement to ensure that chemical components are within the detection range of the detection camera is obviously inefficient, and it still cannot even get rid of the constraints of requiring detection personnel to be stationed in special chemical workshops for a long time. It is still some distance away from the safety and efficiency required for the corrosion resistance detection of special chemical components. Summary of the invention

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0028] 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 invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0030] See also Figure 1-4The present invention provides a technical solution: a corrosion detection device based on chemical conditions, including a detection camera 10 and a storage plate 1 for mounting chemical components 15, a special circle of identification stickers 101, or a ring-shaped identification sticker 101 is provided on one side of the storage plate 1, and the storage plate 1 is rotatably mounted on a vertical driving component 2 in the horizontal plane, that is, the storage plate 1 is mounted on the vertical driving component 2 and can be rotated in the horizontal plane, so that the storage plate 1 can be driven by the vertical driving component 2 to move up and down to the desired height position, for example, to a height that can be detected by the second sensor 12 mentioned later. At the same time, in this embodiment, the vertical driving component 2 is slidably mounted on a horizontal driving component 3, and the horizontal driving component 3 drives the vertical driving component 2 to move horizontally to achieve height adjustment while having the function of adjusting the distance relative to the detection camera 10. Specifically, the detection camera 10 is located outside one side of the storage plate 1, and a sensor is provided at an angle on the upper and lower opposite sides of the detection camera 10. The first sensor 11 located at the top is used to detect whether there is a chemical component 15 within a distance range in the detection direction. The two sensors can determine whether the chemical component 15 is within the corresponding angle range, and the angle is less than Figure 2 ∠B in the figure makes it possible for the placement plate 1 to be slightly away from the detection camera 10 as long as the two sensors detect their respective detection objects, so that the chemical element 15 can be placed in the shooting field of view of the detection camera 10 as a whole, that is, when manufacturing, the detection angle formed by the detection directions of the two sensors is smaller than the shooting angle of view of the detection camera 10, and the angular bisectors of the detection angle and the shooting angle of view are collinear. In practice, a label 101 can be fixedly connected to the side of the placement plate 1 facing the detection camera 10. When in use, the vertical drive component 2 first drives the placement plate 1 to rise until the second sensor 12 can detect and identify the height position of the label 101. At this time, the lower part of the chemical element 15 must be in the field of view of the detection camera 10. During the intermittent rotation of the placement plate 1, if the first sensor 11 detects the chemical element 15, the horizontal drive component 3 drives the vertical drive component 2 to move toward the side away from the detection camera 10 until the first sensor 11 just stops detecting the label 101, that is, the chemical element 15 is just fully observed. In addition, an installation cabin (not shown in the figure) can be fixed at the bottom end of the storage plate 1, and a camera can be set in the installation cabin. At the same time, a camera can be set above the storage plate 1. These two cameras are only turned on when it is necessary to inspect all surfaces of the chemical component 15. The principle can refer to the above-mentioned inspection camera 10.

[0031] In actual operation, for specific surface corrosion detection, the chemical components 15 to be detected can be placed and transported one by one by some existing transport tools to the placement plate 1. For occasions where only local sampling is required, for example, only the surrounding of the chemical component 15 needs to be inspected to determine the corrosion resistance based on the corrosion situation of this part, the chemical component 15 can be dropped into the placement plate 1 in any posture.

[0032] In this embodiment, Figure 1 As shown, the vertical driving component 2 includes a vertical mounting seat 201, a bearing rack 202, a driving gear 203 and a driving motor 8. The bearing rack 202 is vertically and slidably mounted in the vertical mounting seat 201, and a horizontally arranged storage plate 1 is mounted on the top of the bearing rack 202 to achieve the lifting and lowering of the storage plate 1. A detection camera 10 is arranged outside one side of the storage plate 1. One side of the mounting cavity 20101 of the vertical mounting seat 201 for mounting the bearing rack 202 is connected to an annular cavity 20102. A driving gear 203 is rotatably mounted in the annular cavity 20102. The driving gear 203 is connected to the main shaft of the driving motor 8 to achieve the upward movement of the bearing rack 202, and the driving motor 8 is fixed to the back of the annular cavity 20102.

[0033] In this embodiment, Figure 1 The horizontal driving component 3 includes a horizontal mounting seat 301, a hydraulic rod 302 and a pressure spring 303. The upper surface of the horizontal mounting seat 301 is provided with a slide groove along its length direction. The slide groove can be rectangular. A hydraulic rod 302 is installed on one side of the slide groove. The free end of the hydraulic rod 302 is fixedly connected to the bottom of the vertical mounting seat 201 to push the vertical mounting seat 201 to slide horizontally. A pressure spring 303 is horizontally installed on the other side of the slide groove. The pressure spring 303 is in contact with the side of the vertical mounting seat 201 away from the hydraulic rod 302 to maintain the stability of the vertical mounting seat 201. Specifically, when manufacturing, the bottom end of the vertical mounting seat 201 is a T-shaped structure, and the slide groove is a T-shaped slide groove, which can ensure that the vertical mounting seat 201 will never leave the slide groove when it is horizontally slidably installed with the slide groove.

[0034] More specifically, if Figure 1The top of the load-bearing rack 202 is fixed with a seat tube 4 with an open top and a closed bottom. A rotating column 5 is coaxially mounted in the seat tube 4. A first driving gear 6 is coaxially fixed at the bottom of the rotating column 5, and the rim of the first driving gear 6 extends into a notch in the tube wall of the seat tube 4. At the same time, in this embodiment, a storage plate 1 is coaxially fixed to the top of the rotating column 5. The storage plate 1 is placed horizontally, and the bottom end surface of the storage plate 1 is in smooth contact with the tube opening of the seat tube 4. A mounting cover 9 is coaxially sleeved on the outer side of the seat tube 4. The bottom end of the mounting cover 9 is rotatably sleeved on the seat tube 4, and the top cover end of the mounting cover 9 is rotatably connected to the bottom surface of the storage plate 1. In addition, a rotating motor is fixed to the bottom end of the storage plate 1. The rim of the second driving gear 7 driven by the rotating motor extends into the notch, thereby meshing with the first driving gear 6 and sliding vertically with the load-bearing rack 202.

[0035] In this embodiment, Figure 1 The cross section of the end face of the cover wall at the cover opening end of the mounting cover 9 is semicircular, and the bottom end of the storage plate 1 is provided with an annular groove, and the cross section of the annular groove is semicircular, so that the storage plate 1 can rotate flexibly. Figure 5 A protective cover 13 made of transparent anti-corrosion material is also installed on the top surface of the storage plate 1. The top of the protective cover 13 is open and is provided with a conveyor belt 14. The conveyor belt 14 is used to transmit the chemical element 15 to be tested, so that the chemical element 15 falls from the output end of the conveyor belt 14 onto the storage plate 1 in the protective cover 13. This is mainly used for local sampling of unspecified surfaces of the chemical element 15.

[0036] like Figure 1 The load-bearing rack 202 includes two upper and lower racks hinged to each other, wherein the top of the upper rack is connected to the storage plate 1, and after the bottom end of the upper rack is slidably inserted into the vertical mounting seat 201, it is hinged to the top of the lower rack, so that when the load-bearing rack 202 is vertically moved upward to the limit position in the vertical mounting seat 201, once the upper rack is completely exposed outside the vertical mounting seat 201, it will flip and tilt to one side, and automatically dump the chemical components 15 on the storage plate 1. Then the load-bearing rack 202 retreats into the vertical mounting seat 201 and automatically straightens the upper rack. In order to facilitate the reception of the chemical components 15 after inspection, a slide (not shown in the figure) can be provided below the side of the horizontal driving component 3 away from the inspection camera 10. The slide can be installed on the left side of the horizontal driving component 3 so that when the upper rack tilts to the left, it is used to receive the chemical components 15 that have been dumped and slid down from the storage plate 1. It can also be as follows Figure 6 The top port of the mounting cavity 20101 is processed into an upwardly protruding arc-shaped structure 20104 on one side of the end surface for the upper rack to contact when it falls, so as to facilitate the tipping and straightening of the upper rack.

[0037] In this embodiment, Figure 6The hinge shaft 16 of the upper rack and the lower rack is installed on the side of the two racks away from the detection camera 10, as shown in FIG. Figure 1 The left part of the bearing rack 202 is shown, and the upper rack and the lower rack are in flat contact with each other at the side of the detection camera 10, which maintains the stability and reliability during docking, and can prevent the upper rack from turning and tilting toward the side of the detection camera 10. At least one vertical guide groove 20103 is provided on the inner wall of the installation cavity 20101, and at least one end of the hinge shaft 16 is slidably installed in the guide groove 20103 to guide the movement, and the top end of the guide groove 20103 passes through the top end surface of the vertical mounting seat 201.
