Description
Technical Field
[0001] This utility model relates to the field of weld seam inspection technology, and in particular to a cooling device for an FGI high-temperature detection probe. Background Technology
[0002] Saturated field gradient electromagnetic array imaging (FGI) is based on the principle of electromagnetic induction. It excites gradient fields of electric and magnetic fields on the surface of a conductor and measures the three-dimensional size information of the defect by measuring the perturbation of the gradient field by the defect.
[0003] By adding a strong DC magnetic field to the surface gradient field, the penetration depth of the surface induced current is increased, and the change in magnetic permeability caused by internal defects is sensed, thereby realizing the detection of internal defects.
[0004] Existing FGI (Frequency Geometric Inspector) technology primarily relies on manual scanning by inspectors. Due to its advantage of being capable of operating at high temperatures, it is frequently used to inspect high-temperature welds, with temperatures reaching up to 800℃. Therefore, to protect the probe's lifespan, a device that can both protect and rapidly cool the probe is urgently needed. To address these shortcomings, this invention proposes a cooling device for an FGI high-temperature inspection probe. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cooling device for the FGI high-temperature detection probe.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: an FGI high-temperature detection probe cooling device, comprising a side shell and a cooling water tank. A strip-shaped opening is provided on one side of the side shell, through which two symmetrical sliding plates are slidably connected. A cooling plate is fixedly connected to one end of each sliding plate outside the side shell. The cooling plate has a hollow interior. Fans are fixed at the bottom and top of the side shell. An adjustment component for driving the movement of the two sliding plates is provided inside the side shell. A connecting pipe is connected between the two cooling plates. A pump body is installed on the outer wall of the cooling water tank, and the pump body can circulate the cooling water in the cooling water tank into the two cooling plates. A cooling component is installed on the top of the cooling water tank.
[0007] Furthermore, several heat sinks are fixed through and fixed to the sides of the two cooling plates that are far apart from each other.
[0008] Furthermore, the adjustment assembly includes a bidirectional lead screw located inside the side shell, which is rotatably connected to the inner wall of the side shell via a bearing. The bidirectional lead screw passes through two sliding plates and is threadedly connected to the two sliding plates. The adjustment assembly also includes a horizontal shaft passing through the side wall of the side shell and rotatably connected to the side shell via a bearing. A worm gear is fixed to one end of the horizontal shaft located inside the side shell, and a worm wheel is fixed to the middle of the bidirectional lead screw, with the worm gear meshing with the worm wheel. A knob is fixed to one end of the horizontal shaft located outside the side shell.
[0009] Furthermore, a water inlet pipe is fixed to the pump body inlet, and the other end of the water inlet pipe is connected to the inside of the cooling water tank. The two cooling plates are respectively fixed with an inlet pipe and a drain pipe near the end of the connecting pipe. The other end of the inlet pipe is fixedly connected to the pump body outlet, and the other end of the drain pipe is connected to the inside of the cooling water tank.
[0010] Furthermore, the cooling assembly includes a semiconductor refrigeration chip fixed to the upper surface of the cooling water tank, and a plurality of cooling plates are fixed to the cooling side of the bottom of the semiconductor refrigeration chip, with the plurality of cooling plates extending through the top wall of the cooling water tank into the interior of the cooling water tank.
[0011] Furthermore, the top wall of the cooling water tank is provided with a water inlet pipe, and the bottom side wall of the cooling water tank is fixed with a waste outlet pipe.

[0013] 1. In use, the FGI high-temperature detection probe cooling device of this utility model is provided with a side shell, two cooling plates, a heat sink, a fan and an adjustment component. The adjustment component is located inside the side shell. The two cooling plates can be driven to move closer or further apart, so that the detection probe can be clamped by the two cooling plates.

Finally, the fan will remove the temperature from the heat sink, thereby achieving the cooling of the probe.
[0014] 2. In use, the FGI high-temperature detection probe cooling device is equipped with a cooling water tank, a pump body, and a cooling assembly. The cooling assembly cools the water in the cooling water tank, and the pump body circulates the cooling water in the tank into two cooling plates, thereby cooling the detection probe more quickly.

It can also reduce the occurrence of high-temperature burns to a certain extent. Attached Figure Description

[0021] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0022] like Figures 1-3 As shown, a cooling device for an FGI high-temperature detection probe is disclosed, comprising a side shell 1 and a cooling water tank 2. A strip-shaped opening 3 is provided on one side of the side shell 1, through which two symmetrical sliding plates 4 are slidably connected. A cooling plate 5 is fixedly connected to one end of each sliding plate 4 outside the side shell 1. The cooling plate 5 has a hollow interior. Fans 7 are fixed at the bottom and top of the side shell 1. An adjustment component 8 for driving the movement of the two sliding plates 4 is provided inside the side shell 1. A connecting pipe 9 connects the two cooling plates 5. A pump body 10 is installed on the outer wall of the cooling water tank 2, and the pump body 10 can circulate the cooling water in the cooling water tank 2 into the two cooling plates 5. A cooling component is installed on the top of the cooling water tank 2.
[0023] Several heat sinks 6 are fixed to the two cooling plates 5 on the side that is far apart from each other.
[0024] By setting up several heat sinks 6, the heat dissipation area of the cooling plate 5 can be increased, improving the heat dissipation effect. Combined with the fan 7, the heat on the heat sink 6 can be quickly dissipated, achieving the function of air cooling.
[0025] The adjusting assembly 8 includes a bidirectional lead screw 81 located inside the side shell 1. The bidirectional lead screw 81 is rotatably connected to the inner wall of the side shell 1 via a bearing. The bidirectional lead screw 81 passes through two slide plates 4 and is threadedly connected to the two slide plates 4. The adjusting assembly 8 also includes a horizontal shaft 83 that passes through the side wall of the side shell 1 and is rotatably connected to the side shell 1 via a bearing. A worm gear 84 is fixed to one end of the horizontal shaft 83 located inside the side shell 1. A worm wheel 82 is fixed to the middle of the bidirectional lead screw 81, and the worm gear 84 meshes with the worm wheel 82. A knob 85 is fixed to one end of the horizontal shaft 83 located outside the side shell 1.
[0026] Under the transmission action of worm gear 84 and worm wheel 82, after worm gear 84 is rotated by knob 85, worm wheel 82 will drive double-acting screw 81 to rotate. Double-acting screw 81 will then drive two sliding plates 4 to move closer or further apart, thereby causing two cooling plates 5 to move closer or further apart. After the two cooling plates 5 clamp the detection probe, the detection probe can be cooled.
[0027] A water inlet pipe 11 is fixed to the inlet of the pump body 10, and the other end of the water inlet pipe 11 is connected to the inside of the cooling water tank 2. Two cooling plates 5 are respectively fixed with an inlet pipe 12 and a drain pipe 13 near the end of the connecting pipe 9. The other end of the inlet pipe 12 is fixedly connected to the outlet of the pump body 10, and the other end of the drain pipe 13 is connected to the inside of the cooling water tank 2.
[0028] Water can be drawn out of the cooling water tank 2 by the pump body 10, and then pumped into one of the cooling plates 5 through the water inlet pipe 12. Then the cooling water enters the other cooling plate 5 along the connecting pipe 9, and finally returns to the cooling water tank 2 along the drain pipe 13, thereby realizing the circulating cooling and cooling of the cooling plate 5.
[0029] The cooling assembly includes a semiconductor cooling chip 14 fixed to the upper surface of the cooling water tank 2. Several cooling chips 15 are fixed to the cooling side of the bottom of the semiconductor cooling chip 14. The cooling chips 15 extend through the top wall of the cooling water tank 2 into the interior of the cooling water tank 2.
[0030] The semiconductor cooling chip 14 can cool the cooling plate 15, and the cooling plate 15 can then cool the water in the cooling water tank 2.
[0031] The top wall of the cooling water tank 2 is provided with a water inlet pipe 16, and the bottom side wall of the cooling water tank 2 is fixed with a waste discharge pipe 17.

[0032] Water can be added to the cooling water tank 2 through the water inlet pipe 16, and the water can be drained through the waste outlet pipe 17 after use.
[0033] Working principle: Two cooling plates 5 are placed on the outside of the detection probe. Then, by rotating the knob 85, the two cooling plates 5 are clamped onto the surface of the detection probe. Next, the fan 7, pump body 10 and semiconductor cooling chip 14 are started. The semiconductor cooling chip 14 can continuously cool the water in the cooling water tank 2. The pump body 10 circulates the cooling water in the cooling water tank 2 into the two cooling plates 5. The cooling plates 5 then cool the detection probe. During the cooling and heat exchange process, the temperature of the heat sink 6 will rise. At this time, the fan 7 will remove the heat from the heat sink 6, thereby achieving dual cooling of water cooling and air cooling.
