Technical Field

[0001] This utility model relates to the field of cobalt source rod detection, and in particular to an underwater descaling identification device for cobalt source rods. Background Technology

[0002] A cobalt source rod is a rod-shaped radiation source made by encapsulating the radioactive isotope cobalt-60 in a specific form within a metal casing. It is the core physical carrier of cobalt sources in practical applications, and is most commonly found in industrial irradiation devices and medical equipment.

[0003] Currently, before using cobalt source rods, it is necessary to identify the source rod's cobalt source number. However, since cobalt source rods are usually stored in source water wells at a depth of 7-8m, the process of identifying the source rod's cobalt source number is very inconvenient and needs to be improved. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide an underwater descaling and identification device for cobalt source rods, which facilitates the identification of cobalt source numbers on the cobalt source rods.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an underwater descaling and identification device for a cobalt source rod, comprising: Identify the base, which is vertically installed inside the water storage well; The positioning tube is vertically installed inside the identification base, and the source rod is vertically inserted through it; The identification support is vertically mounted on the identification base; A camera is mounted on the identification support and faces the positioning tube; A support base is disposed within the identification base and located below the positioning tube, and is used to support the source rod; A clamp is disposed on the identification base and is used to fix the source rod.

[0015] The present invention will be further described in detail below with reference to the accompanying drawings.

[0016] like Figure 1 , Figure 2 As shown, an underwater descaling identification device for a cobalt source rod includes an identification base 1, a positioning tube 2, an identification support 3, a camera 4, a support 5, and a clamp 6.

[0017] like Figure 1 , Figure 2 As shown, the identification base 1 is vertically installed inside the water storage well, and the positioning tube 2 is vertically installed inside the identification base 1, allowing the source rod to pass through vertically. Both ends of the positioning tube 2 are flared to guide the source rod and facilitate its insertion and removal. The identification support 3 is vertically installed on the identification base 1, and the camera 4 is installed on the identification support 3, facing the positioning tube 2.

[0018] like Figure 1 , Figure 2 As shown, the support 5 is disposed inside the identification base 1 and located below the positioning tube 2, and is used to support the source rod.

[0019] like Figure 2 , Figure 3 As shown, a sliding seat 7 is vertically arranged at the bottom of the identification base 1, a sliding rod 71 is vertically slidably connected to the sliding seat 7, a screw 72 is vertically rotatably connected to the sliding seat 7, the sliding rod 71 is threadedly connected to the screw 72, and the support seat 5 is fixed to the sliding rod 71.

[0020] like Figure 2 , Figure 4 As shown, the clamp 6 is mounted on the identification base 1 and is used to fix the source rod. The clamp 6 includes a clamp seat 61, a pair of clamp rods 62 and a bidirectional lead screw 63.

[0021] like Figure 4 As shown, a clamp 61 is mounted on the identification base 1, and a pair of clamping rods 62 are horizontally mounted on the clamp 61, extending directly above the positioning tube 2. The ends of the clamping rods 62 are provided with semi-circular notches 64 for inserting the end of a source rod, and for clamping the source rod. A bidirectional lead screw 63 is rotatably connected to the clamp 61 and threadedly connected to the pair of clamping rods 62.

[0022] When it is necessary to identify the cobalt source number of the source rod, first control the screw 72 to rotate, causing the sliding rod 71 and the support 5 to move upward. Then, vertically insert the source rod into the positioning tube 2, at which point the lower end of the source rod is inserted into the support 5. Subsequently, control the screw 72 to rotate in the opposite direction, causing the sliding rod 71 and the support 5 to move downward, and driving the source rod to move slowly downward.

[0023] Because the source rod is a thin tube mechanism containing a radioactive cobalt source, it cannot be clamped. However, the two ends of the source rod are solid structures and can be clamped. Therefore, when the end of the source rod is located between a pair of clamping rods 62, the bidirectional lead screw 63 is controlled to rotate, so that the pair of clamping rods 62 move closer to each other. At this time, the end of the source rod is clamped by the pair of clamping rods 62, thus achieving the clamping and fixing of the source rod.

[0024] Then, the camera 4 illuminates the end of the source rod to identify its cobalt source number. After identification, the pair of clamping rods 62 are moved away from each other to release the source rod from its fixation. Then, the support 5 is moved upward again to move the source rod upward, making it easier to remove and unload the source rod.

[0025] In actual operation, if it is necessary to flip the source rod to identify the cobalt source number, the source rod can be reversed and inserted into the positioning tube 2 to identify the cobalt source number on the other end.

[0026] like Figure 2 , Figure 5 As shown, a column 8 is vertically mounted on the identification base 1, and a cantilever 81 is horizontally rotatably connected to the column 8. A brush head 82 is located at the end of the cantilever 81, directly above the positioning tube 2.

[0027] like Figure 2 , Figure 5 As shown, the brush head 82 is provided with a bolt 83 that passes through the cantilever 81, and a nut 84 that tightens the cantilever 81 is threaded onto the bolt 83, so as to facilitate the replacement of brush heads 82 made of different materials.

[0028] like Figure 2 , Figure 5 As shown, a control motor 85 is provided on the identification base 1, and a crank-connecting rod mechanism 86 is provided between the control motor 85 and the cantilever 81.

[0029] When scale forms at the end of the source rod, the cobalt source number at the end of the source rod will be covered and cannot be seen. Therefore, the control motor 85 can be started, and under the action of the crank connecting rod mechanism 86, the cantilever 81 will swing back and forth. At this time, the cantilever 81 drives the brush head 82 to move synchronously, so as to clean and remove scale from the end of the source rod and ensure that the cobalt source number can be clearly seen and identified.

[0030] The specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
