At present, the inspection of the internal and external surfaces of boiler pressure vessels by the boiler pressure vessel inspection department is completely carried out manually. The inspectors use flashlights and steel hammers to continuously illuminate and knock. For the inspection of higher boilers or pressure vessels, scaffolding must be set up, and only with the help of scaffolding can the inspection be carried out. For the inspection of the inner surface of the boiler pressure vessel, the inspectors must also drill into the interior. This inspection method wastes a lot of time, and the measurement accuracy is low, and it is easy to miss inspections and incomplete inspections, which is less practical.

[0025] Further Figure 1 , Figure 2 and Figure 4 As shown, it is worth explaining in detail that there are four sensors 5, which are a temperature sensor, a pressure sensor, an ultrasonic flaw detector and a high-temperature flaw detector. The four sensors 5 are respectively installed on the adjustment mechanism 4 to facilitate adjustment and improve the accuracy of inspection.

[0026] Further Figure 2 and Figure 3 As shown, it is worth explaining in detail that the fixing rod 301 is arranged in a hollow cylinder, and the detection rod 2 is matched with the inside of the fixing rod 301 to facilitate installation.

[0027] Further Figure 3 As shown, it is worth explaining in detail that the bayonet 303 is set at one end of the rotating sleeve 302 at the bottom opening of the rotating sleeve 302, and the surface of the rotating sleeve 302 is provided with an anti-slip groove.

[0028] According to the above working process, it can be known that: through the positioning mechanism 3, when the detection rod 2 and the positioning plate 1 are installed, the installation limit work can be realized more conveniently and quickly, so that it is easy to carry it during the detection work, and it is easy to disassemble, which is conducive to moving it after disassembly, thereby improving the practicality of the device.

[0029] Further Figure 1 , Figure 2 and Figure 4 As shown, it is worth specifically explaining that the adjustment mechanism 4 includes a motor 401, which is fixedly installed in the bottom end of the detection rod 2, and the bottom end of the motor 401 is fixedly connected to a threaded rod 402, and a bearing 403 is installed at the intersection of the threaded rod 402 and the bottom end of the detection rod 2, and the bottom end of the threaded rod 402 is fixedly connected to a limiting plate 404, and the outer surface of the threaded rod 402 is threadedly connected to a movable sleeve 405, and the outer surface of the movable sleeve 405 is fixedly connected to four connecting blocks 406, and the four connecting blocks 406 are evenly arranged on the surface of the movable sleeve 405. A hinged plate 407 is fixedly connected to the outside of the connecting block 406, and a connecting rod 408 is hingedly installed on the outside of the hinged plate 407. The top of the outer surface of the connecting rod 408 is connected to the sensor 5, and an adjusting rod 409 is hingedly installed on the upper end of the connecting rod 408. A connecting plate 4010 is hingedly installed on the upper end of the adjusting rod 409. The connecting plate 4010 is fixedly connected to a fixed block 4011 on one side close to the threaded rod 402, and a fixed sleeve 4012 is fixedly connected to the other side of the fixed block 4011. The fixed sleeve 4012 is fixedly connected to the outer side of the bottom end of the detection rod 2.

[0030] By rotating the motor 401, the threaded rod 402 is driven to rotate, so that the movable sleeve 405 is threadedly moved on the threaded rod 402. Since the connecting rod 408 and the adjusting rod 409 are hinged, and are hinged to the movable sleeve 405 and the fixed sleeve 4012 through the hinge plate 407 and the connecting plate 4010, the connecting rod 408 and the adjusting rod 409 are folded with each other under the threaded movement of the movable sleeve 405, thereby realizing the adjustment of the sensor 5 to improve the inspection accuracy of the inside of the pressure vessel.

[0031] This scheme has the following working process: when this device is used, the detection rod 2 is installed on the bottom of the positioning plate 1 through the positioning mechanism 3, and at this time, the rotating sleeve 302 is rotated to make the bayonet 303 and the through hole 304 match each other, so that the positioning rod 305 is inserted into the rotating sleeve 302 through the bayonet 303, and the rotating sleeve 302 is rotated to make the detection rod 2 rotate, so that the positioning rod 305 is clamped on the fixed rod 301 through the bayonet 303 and the through hole 304, and the top of the detection rod 2 is pressed on the pressure plate 306, and under the elastic force of the spring 307, the detection rod 2 is stably clamped on the fixed rod 301 through the positioning rod 305, thereby realizing the installation of the detection rod 2, so as to facilitate The positioning plate 1 places the device in the pressure vessel for inspection. At the same time, the rotation of the motor 401 can easily drive the threaded rod 402 to rotate, so that the movable sleeve 405 can move on the threaded rod 402. Since the connecting rod 408 and the adjusting rod 409 are hinged, and are hinged to the movable sleeve 405 and the fixed sleeve 4012 through the hinge plate 407 and the connecting plate 4010, the connecting rod 408 and the adjusting rod 409 are folded with each other under the threaded movement of the movable sleeve 405, so that the sensor 5 installed on the connecting rod 408 is away from the threaded rod 402, which makes it convenient to adjust it adaptively according to the internal space size of the pressure vessel to improve the inspection accuracy of the interior.

[0032] In summary: through the setting of the positioning mechanism 3, when the detection rod 2 and the positioning plate 1 are installed, the installation limit work can be realized more conveniently and quickly, so that it is convenient to carry it during the detection work, and it is convenient to disassemble it, which is conducive to moving it after disassembly, thereby improving the practicality of the device; through the setting of the adjustment mechanism 4, when the inspection and detection work is carried out in the pressure vessel, the position of the sensor 5 can be adjusted according to the size of its internal space, so as to cooperate with the space inside the pressure vessel to realize high-precision inspection and detection work, thereby improving the accuracy of the inspection.
