DETAILED DESCRIPTION

[0022] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0023] This embodiment provides a special flaw detection device for thermal power plants, which is used to perform flaw detection on thermal power plant equipment. The device can conveniently hold and support the flaw detector host 1, making the flaw detection device more convenient to use and ensuring the use effect of the flaw detection device.

[0024] See also Figure 1 to Figure 5A special flaw detection equipment for a thermal power plant includes a flaw detector host 1. A display screen 2 is arranged on the front of the flaw detector host 1. The display screen 2 can be used to conveniently display the flaw detection of the thermal power plant. A group of buttons 3 arranged at equal distances are arranged on the front of the flaw detector host 1. The buttons 3 can be used to conveniently operate the device.

[0025] A cable 4 is installed on the outer surface of the flaw detector host 1, and a probe 5 is installed at one end of the cable 4 away from the flaw detector host 1. The set probe 5 can be used to conveniently detect the equipment in the thermal power plant, and the set cable 4 can be used to facilitate the probe 5 to transmit the signal to the flaw detector host 1 for display.

[0026] A protection box 6 is installed on the outer surface of the flaw detector main body 1, and the probe 5 is located inside the protection box 6. Inserting the probe 5 into the protection box 6 can protect the probe 5 and prevent the probe 5 from being damaged.

[0027] A limiting assembly 7 is installed on the inner wall of the protective box 6, and the limiting assembly 7 includes a cylinder 701 fixedly embedded in the inner wall of the protective box 6, and a slide 702 is slidably connected to the inner wall of the cylinder 701. A limiting rod 703 is installed on the outer surface of the slide 702. The end of the limiting rod 703 away from the slide 702 is rotatably connected to a ball 704, and the ball 704 is in contact with the probe 5. A spring 705 is installed between the slide 702 and the cylinder 701.

[0028] One end of the limiting rod 703 away from the slide plate 702 penetrates the inner wall of the cylinder 701 and extends to the outside of the cylinder 701 , and the outer surface of the limiting rod 703 is slidably connected to the penetration point of the cylinder 701 , and the slide plate 702 can slide on the inner wall of the cylinder 701 .

[0029] When the probe 5 is inserted into the protective box 6, the probe 5 can push the limit rod 703 and the ball 704 to move, so that the limit rod 703 shrinks to the inside of the cylinder 701, and the spring 1 705 can be compressed. When the probe 5 is inserted into the protective box 6, the elastic force of the spring 1 705 can act on the limit rod 703 and the ball 704, which can limit the probe 5 to a certain extent and protect the probe 5.

[0030] An articulated frame 8 is installed on the back of the flaw detector mainframe 1 , a gripping rod 9 is arranged inside the articulated frame 8 , a pin 10 is fixedly embedded on the outer surface of the gripping rod 9 , and the pin 10 is rotatably connected to the articulated frame 8 .

[0031] The pin shaft 10 is rotatably connected to the articulated frame 8 via a bearing, which can ensure the stability of the pin shaft 10 during rotation. The provided gripping rod 9 can be used to conveniently support and hold the flaw detector host 1.

[0032] An anti-slip sleeve 11 is installed at one end of the grip rod 9 away from the flaw detector mainframe 1. The anti-slip sleeve 11 can increase the friction force at the end of the grip rod 9 and ensure the stability of the grip rod 9 when supporting the flaw detector mainframe 1.

[0033] Two symmetrical damping assemblies 12 are installed on the outer surface of the articulated frame 8. The damping assembly 12 includes a connecting plate 121 fixedly connected to the outer surface of the articulated frame 8. A spring 2 122 is fixedly connected to the outer surface of the connecting plate 121. An arc frame 123 is installed at one end of the spring 2 122 away from the connecting plate 121. An arc damping block 124 is installed on the inner wall of the arc frame 123, and the inner wall of the arc damping block 124 is in contact with the pin shaft 10.

[0034] When the handle 9 rotates, it can drive the pin 10 to rotate. The spring 122 can provide elastic force for the arc frame 123, so that the arc damping block 124 can damp the pin 10, thereby avoiding unnecessary rotation of the handle 9 during use and adjusting the angle of the handle 9 to the desired angle for use, thereby facilitating the use of the device.

[0035] Two symmetrical slide cylinders 125 are installed on the outer surface of the connecting plate 121 . The inner walls of the two slide cylinders 125 are slidably connected with slide rods 126 , and the slide rods 126 are connected to the arc frame 123 .

[0036] The provided slide cylinder 125 and the slide rod 126 can be used to guide and limit the arc frame 123, thereby ensuring the stability of the arc frame 123 when moving.

[0037] A set of line cards 13 are installed on the upper surface of the flaw detector host 1, and the line card 13 is adapted to the cable 4. When the device is in use, the cable 4 is inserted into the inside of the line card 13, which can limit and organize the cable 4 to prevent the cable 4 from being too messy when not in use and causing the cable 4 to break.

[0038] Working principle: When the device is in use, the display screen 2 is used to conveniently observe the test results, and the probe 5 is used to conveniently perform flaw detection on the thermal power plant equipment. After use, the probe 5 is inserted into the interior of the protective box 6. When the probe 5 is inserted into the interior of the protective box 6, the bottom end of the probe 5 can push the ball 704 and the limit rod 703 to move, and the slide plate 702 can slide on the inner wall of the cylinder 701, and the spring 1 705 can be compressed. When the probe 5 is inserted into the interior of the protective box 6, the elastic force of the spring 1 705 can act on the limit rod 703 and the ball 704, so as to limit the probe 5 to a certain extent and protect the probe 5. When the grip 9 is rotated to a position perpendicular to the flaw detector main unit 1, the grip 9 and the anti-slip sleeve 11 can support the flaw detector main unit 1, which can facilitate the placement of the flaw detector main unit 1 for use. When the grip 9 is rotated to a vertical position downward, the set grip 9 can be used to conveniently hold the flaw detector main unit 1 and to facilitate the use of the flaw detector main unit 1. When the grip 9 is rotated, the pin 10 can be driven to rotate. The set spring 122 can provide elastic force for the arc frame 123, so that the arc damping block 124 can damp the pin 10, which can avoid unnecessary rotation of the grip 9 during use and can adjust the angle of the grip 9 to a desired angle for use, thereby facilitating the use of the device.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
