[0002] After long-term use, the inner surface of the boiler is prone to deformation, such as concave, rust and crack, etc. The deformation of the inner surface of the boiler may cause problems in the operation of the boiler, thereby causing production hazards. Therefore, it is necessary to regularly detect the inner surface of the boiler to ensure the normal operation of the boiler.

[0003] Chinese patent CN118936407A discloses a device and method for monitoring the expansion deformation of a power station boiler body. The device for monitoring the expansion deformation of the power station boiler body comprises a supporting ring for concentrically sleeving outside the boiler body, a chassis is arranged at the bottom of the supporting ring, and a deformation detection mechanism is arranged in a circular array on the supporting ring. The real-time displacement value of the displacement sensor is periodically collected during the use of the boiler body, and the difference between the real-time displacement value of the displacement sensor and the initial value of the displacement sensor is obtained to obtain the deformation value of the corresponding area of the boiler body. The deformation of the local boiler body can be identified by the multiple deformation detection mechanisms arranged in a circular array on the supporting ring, and the monitoring effect is improved.

When the expansion amount D of the boiler at the jth test block of the ith point is greater than zero, it indicates that the boiler deforms. When the expansion amount D of the boiler at the jth test block of the ith point is less than or equal to zero, it indicates that the boiler does not deform, which is beneficial to accurate monitoring.

[0033] The present application has the following technical effects:

[0034] Before monitoring, the horizontal rotating assembly of the monitoring assembly drives the vertical adjusting assembly to rotate, the vertical adjusting assembly drives the ultrasonic transceiver to rotate along the horizontal rotating assembly, and then the vertical adjusting assembly drives the ultrasonic transceiver to rotate along the vertical adjusting assembly. The ultrasonic transceiver is rotated to face the cleaning assembly, the cleaning assembly is moved to contact the ultrasonic transceiver, the cleaning assembly cleans the dust on the irradiation end surface of the ultrasonic transceiver, and the dust is prevented from affecting the monitoring of the ultrasonic transceiver. After the dust is cleaned, the cleaning assembly is separated from the ultrasonic transceiver, the vertical adjusting assembly drives the ultrasonic transceiver and the closed auxiliary assembly to rotate to be vertically downward, the closed auxiliary assembly is combined with the vertical adjusting assembly to form a closed box, the closed box can prevent flowing air from affecting the calibration of the ultrasonic transceiver, the temperature sensor monitors the temperature T in the closed box, calculates the ultrasonic wave propagation speed C T under the current temperature through a temperature compensation algorithm, starts the ultrasonic transceiver, the ultrasonic transceiver emits ultrasonic waves to the connecting frame, then receives the reflected ultrasonic waves from the connecting frame, calculates the time length t of ultrasonic wave transmission and reception, calculates the test distance M = C T *t, and then calculates whether M is twice the distance between the irradiation end of the ultrasonic transceiver and the top of the connecting frame. If yes, it indicates that the ultrasonic transceiver is in a qualified state and can be monitored subsequently. If not, it indicates that the ultrasonic transceiver is in a state that needs to be adjusted and cannot be detected subsequently, realizing self-calibration of the ultrasonic transceiver and being beneficial to actual use. During monitoring, the moving trolley drives the ultrasonic transceiver to move to the i-th horizontal point, the horizontal rotating assembly and the vertical adjusting assembly cooperate to drive the ultrasonic transceiver to face the j-th vertical test block, the temperature sensor monitors the temperature T of the j-th test block at the i-th point, and then converts into an isothermal environment, the isothermal environment temperature is T eq , and the ultrasonic wave propagation speed C eq under the isothermal environment temperature T is calculated through a temperature compensation algorithm.T Then, the wind speed and direction sensor detects the wind speed v at the j-th test block of the i-th point. w,i,j Then, the ultrasonic propagation speed C at the j-th test block of the i-th point is calculated using a wind compensation algorithm. W,i,j Then, the ultrasonic wave reflected back from the connecting frame is received, and the time t from the ultrasonic wave's transmission to reception is calculated. i,j Then through t i,j and C W,i,j The distance between the ultrasonic transceiver and the test block was measured, and the distance value between the ultrasonic transceiver and the test block was S. i,j Then S i,j The expansion amount D of the boiler at the j-th test block at the i-th point is calculated using an expansion amount algorithm. If the expansion amount D at the j-th test block at the i-th point is greater than zero, it indicates that the boiler has deformed; if the expansion amount D at the j-th test block at the i-th point is less than or equal to zero, it indicates that the boiler has not deformed. This facilitates accurate monitoring. Mobile monitoring eliminates the need for multiple ultrasonic transceivers, reducing operating costs and maintenance workload. Furthermore, the non-contact measurement between the ultrasonic transceiver and the boiler minimizes damage to the transceiver due to the high temperature on the boiler's outer wall, ensuring monitoring accuracy. The cleaning component cleans the dust from the ultrasonic transceiver and can also perform self-cleaning, reducing dust residue on the cleaning component and facilitating its subsequent use.
