Description

Technical Field

[0001] This utility model relates to the field of cobalt source rod detection, and in particular to a camera hoist for underwater appearance inspection of 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, an appearance inspection of the cobalt source rods is required. However, since cobalt source rods are usually stored in water wells at a depth of 7-8m, the underwater camera is usually suspended and fixed with slings before being submerged in the water to achieve the appearance inspection of the source rods.

[0004] However, because the sling swings freely in the water storage well, the underwater camera will sway along with the sling, affecting the stability of the underwater camera during operation and thus affecting the appearance inspection of the cobalt source rod, which needs to be improved. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a camera hoist for underwater appearance inspection of cobalt source rods, which can improve the stability of the appearance inspection process of source rods.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an underwater camera rigging for inspecting the appearance of a cobalt source rod, comprising:

[0007] The boom extends vertically into the water storage well;

[0008] A lifting ring, U-shaped, is positioned at the upper end of the lifting rod;

[0009] A square tube is laid horizontally across the water storage well and passes through the lifting ring horizontally.

[0010] A flange is provided at the lower end of the lifting rod and is arranged in a C-shape;

[0011] The mounting base is arranged in the shape of a round tube and is used to connect the underwater camera and to be embedded in the flange;

[0012] The mounting plate is disposed on the outer wall of the mounting base and is fixed to the flange by screws.

[0013] In a preferred embodiment, the present invention can be further configured such that: both sides of the mounting plate are provided with circular holes for the nut positions of the screws to pass through, and the mounting plate is provided with strip-shaped holes that communicate with the circular holes and allow the screw shank to slide and be embedded.

[0014] In a preferred embodiment, the present invention can be further configured such that: the mounting plate is provided with a groove for the nut position of the screw to be inserted, the groove being located at one end of the strip hole away from the round hole.

[0015] In a preferred embodiment, the present invention can be further configured such that a retaining ring is provided on the lower outer wall of the screw.

[0016] In a preferred embodiment, the present invention can be further configured as follows: a rotating shaft is provided on the flange, passing through the lower end of the lifting rod, the rotating shaft is rotatably connected to the lifting rod, a wing bolt is threaded to the bottom of the lifting rod, a plug is provided on the wing bolt, and a pair of mutually perpendicular insertion holes are provided on the rotating shaft for the insertion of the plug.

[0017] In a preferred embodiment, the present invention can be further configured such that: a limiting groove is provided on the outer wall of the rotating shaft, and a limiting rod is horizontally provided on the lifting rod and embedded in the limiting groove.

[0018] In a preferred embodiment, the present invention can be further configured such that the boom comprises multiple boom segments, and adjacent boom segments are connected by threaded joints.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. By setting up a dedicated lifting device, the mounting base is fixed to the underwater camera, and the mounting base is also fixed to the lower end of the boom, so that the boom can control the underwater camera to extend into the source water well. At the same time, the square tube is placed across the source water well and the boom is fixed, so that the underwater camera can stably illuminate the source rod and achieve stable appearance inspection of the cobalt source rod.

[0021] 2. By setting an adjustable flange, the installation requirements of underwater cameras in different directions can be met, adapting to different detection scenarios and improving practicality;

[0022] 3. By setting up segmented suspension rods, it is possible to assemble the suspension rods on-site and disassemble and store them after use, making them convenient for reuse. Attached Figure Description

[0028] The present invention will be further described in detail below with reference to the accompanying drawings.

[0029] like Figure 1 , Figure 2 As shown, an underwater camera hoist for inspecting the appearance of a cobalt source rod includes a hoisting rod 1, a hoisting ring 2, a square tube 3, a flange 4, a mounting base 5, and a mounting plate 6.

[0030] like Figure 1 , Figure 2 As shown, the boom 1 extends vertically into the water storage well, and the lifting ring 2 is U-shaped and located at the upper end of the boom 1. The square tube 3 is laid horizontally across the water storage well and passes through the lifting ring 2 to suspend and fix the boom 1.

[0031] like Figure 2 , Figure 3 As shown, flange 4 is located at the lower end of boom 1 and is C-shaped. Mounting base 5 is tubular and connects to the underwater camera, serving as an insert within flange 4. Mounting plate 6 is located on the outer wall of mounting base 5 and is fixed to flange 4 by screws 7.

[0032] like Figure 3 As shown, both sides of the mounting plate 6 are provided with round holes 61 for the nut positions of the screws 7 to pass through, and the mounting plate 6 is provided with strip holes 62 that connect to the round holes 61 and allow the screws 7 to slide into the holes.

[0033] like Figure 3 As shown, the mounting plate 6 is provided with a groove 63 for the nut position of the screw 7 to be inserted. The groove 63 is located at the end of the strip hole 62 opposite to the round hole 61, and a retaining ring 71 is provided on the lower outer wall of the screw 7 to prevent the screw 7 from falling out.

[0034] When underwater visual inspection of the cobalt source rod is required, first fix the mounting base 5 to the underwater camera, then embed the mounting base 5 into the flange 4, aligning the screw 7 on the flange 4 with the round hole 61 on the mounting plate 6. Next, control the mounting base 5 to move downwards, so that the nut of the screw 7 passes through the round hole 61. Then, control the mounting base 5 to rotate, so that the screw shank of the screw 7 is embedded in the slotted hole 62. Finally, tighten the screw 7, so that the nut is embedded in the groove 63, thus achieving the connection and fixation between the mounting base 5 and the flange 4.

[0035] Then, control the entire boom 1 to drive the underwater camera into the storage well, and pass the square tube 3 through the lifting ring 2 on the boom 1 and place it across the storage well to suspend and fix the underwater camera. At this time, the underwater camera can be used to irradiate the cobalt source rod to achieve the appearance inspection of the cobalt source rod.

[0036] like Figure 2 , Figure 4 As shown, a rotating shaft 41 is provided on the flange 4, which passes through the lower end of the hanger rod 1 and is rotatably connected to the hanger rod 1.

[0037] like Figure 4 As shown, a limiting groove 42 is provided on the outer wall of the rotating shaft 41, and a limiting rod 43 embedded in the limiting groove 42 is horizontally provided on the lifting rod 1.

[0038] like Figure 4 As shown, a wing bolt 44 is threaded to the bottom of the boom 1, and a plug rod 45 is provided on the wing bolt 44. The rotating shaft 41 is provided with a pair of mutually perpendicular insertion holes 46 for inserting the plug rod 45.

[0039] When it is necessary to fix the underwater camera horizontally or vertically, the control flange 4 drives the rotating shaft 41 to rotate, so that the flange 4 rotates to a horizontal or vertical position. Then, the control butterfly bolt 44 rotates, so that the insertion rod 45 is inserted into the corresponding insertion hole 46, thereby fixing the flange 4. This meets the installation requirements of underwater cameras in different directions, adapts to different detection scenarios, and improves practicality.

[0040] like Figure 2 As shown, the boom 1 comprises multiple boom segments 11, with adjacent boom segments 11 connected by threaded joints 12. Therefore, by designing the boom 1 as a segmented structure, on-site assembly and disassembly for storage after use are possible, facilitating reuse.
