Description

Technical Field

[0001] This invention relates to the field of boiler inspection technology, specifically to a mobile boiler appearance deformation real-time monitoring device and method. Background Technology

[0002] After prolonged use, the inner surface of a boiler is prone to deformation, such as dents, rust, and cracks. Deformation of the boiler's inner surface can cause malfunctions and production hazards. Therefore, it is necessary to regularly inspect the inner surface of the boiler to ensure its normal operation.

[0003] Chinese Patent CN118936407A discloses a device and method for monitoring the expansion and deformation of a power plant boiler body. The device includes a support ring concentrically mounted on the outside of the boiler body. A base frame is provided at the bottom of the support ring, and deformation detection mechanisms are arranged in a circumferential array on the support ring. During boiler use, the invention periodically collects real-time displacement values ​​from displacement sensors and calculates the difference between these real-time displacement values ​​and the initial values ​​of the displacement sensors to obtain the deformation values ​​of the areas on the boiler body corresponding to the deformation detection mechanisms. By arranging multiple deformation detection mechanisms in a circumferential array on the support ring, the deformation of multiple areas around the boiler body can be monitored separately, enabling the identification of localized deformation and improving monitoring effectiveness.

[0004] However, the aforementioned patent requires multiple monitoring devices for a single boiler, which is even more needed when monitoring multiple boilers, resulting in high actual costs. In addition, the maintenance workload is large, which is not conducive to practical use. Furthermore, due to the high temperature of the boiler's outer wall, the sensitivity of the displacement sensor is easily damaged when it is under high temperature for a long time.

[0005] Based on this, the present invention designs a mobile boiler appearance deformation real-time monitoring device and method to solve the above problems. Summary of the Invention

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a mobile boiler appearance deformation real-time monitoring device and method.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A mobile boiler appearance deformation real-time monitoring device, including a mobile trolley;

[0009] The top of the mobile trolley is connected from left to right to a cleaning component for wiping dust off the monitoring end of the monitoring component, a monitoring component for multi-dimensional angle adjustment monitoring and self-calibration, and a wind speed and direction sensor for wind speed and direction testing. The cleaning component also has a self-cleaning function.

[0010] The monitoring component includes a horizontal rotation component, a vertical adjustment component, a closed auxiliary component, an ultrasonic transceiver, a connecting frame, and a test block. The horizontal rotation component is connected to the moving trolley. The vertical adjustment component is fixedly connected to the top of the output end of the horizontal rotation component. The closed auxiliary component and the ultrasonic transceiver are both fixedly installed on the drive end of the vertical adjustment component. The closed auxiliary component is located outside the ultrasonic transceiver. When the closed auxiliary component rotates to the vertical position, the vertical adjustment component and the closed auxiliary component are combined into a closed box, and the ultrasonic transceiver is located inside the ultrasonic transceiver. The connecting frame is fixedly installed at the bottom inside the vertical adjustment component. The test block is fixedly installed on the outer wall of the boiler. During monitoring, the test block is set perpendicular to the irradiation end of the ultrasonic transceiver. When the ultrasonic transceiver rotates to face the cleaning component, the cleaning component moves to contact the irradiation end of the ultrasonic transceiver.

[0011] A temperature sensor for detecting ambient temperature is fixedly connected to the top of the enclosed auxiliary component, and the sensing end of the temperature sensor and the transmitting end of the ultrasonic transceiver are arranged in parallel.

[0012] Furthermore, the horizontal rotation assembly includes a hollow shaft, a third gear ring, a fourth gear ring, and a second motor. The moving trolley is rotatably connected to the hollow shaft via bearings. The second motor is fixedly installed at the bottom of the moving trolley, the fourth gear ring is fixedly installed at the drive end of the second motor, the second motor is meshed with the third gear ring, the bottom of the hollow shaft is fixedly installed in the mounting hole opened in the second motor, and the top of the hollow shaft is fixedly connected to the vertical adjustment assembly.

[0013] Furthermore, the vertical adjustment component includes a housing, a first motor, and a horizontal shaft. The bottom of the housing is fixedly installed on the top of the hollow shaft, the first motor is fixedly installed on the upper end of the outer wall of the housing, the drive end of the first motor passes through the housing and is fixedly connected to the horizontal shaft, the top of the housing has a straight groove, and the bottom of the straight groove is located at the lower middle end of the housing, and the horizontal shaft is fixedly connected to the closed auxiliary component.

[0014] Furthermore, the enclosed auxiliary components include an n-shaped plate and a connecting frame. Two sets of connecting frames are symmetrically fixedly installed on the horizontal axis. The outer end of the horizontal axis is fixedly connected to the inner top of the n-shaped plate. The front and rear side walls of the n-shaped plate are slidably connected to the inner wall of the box. When the n-shaped plate is in a vertical state, the bottom of the n-shaped plate is in contact with the bottom of the straight groove, and the top of the n-shaped plate is flush with the top of the hollow shaft.

[0015] Furthermore, the temperature sensor is fixedly mounted on the top of the n-shaped plate.

[0016] A monitoring method for a mobile boiler appearance deformation real-time monitoring device includes the following steps:

[0017] Step 1: The horizontal rotation component of the monitoring component drives the vertical adjustment component to rotate, which in turn drives the horizontal rotation component to rotate. Then, the vertical adjustment component drives the ultrasonic transceiver to rotate along the vertical adjustment component. The ultrasonic transceiver rotates until it is directly facing the cleaning component. The cleaning component moves to make contact with the ultrasonic transceiver and cleans the dust on the surface of the ultrasonic transceiver's irradiation end.

[0018] Step Two: The vertical adjustment component rotates the ultrasonic transceiver and the enclosed auxiliary component until they are vertically downwards. The enclosed auxiliary component and the vertical adjustment component combine to form an enclosed enclosure. The enclosed enclosure prevents airflow from affecting the ultrasonic transceiver calibration. The temperature sensor monitors the temperature T inside the enclosed enclosure, and the ultrasonic wave propagation speed C at the current temperature is calculated using a temperature compensation algorithm. T The ultrasonic transceiver is activated, emitting ultrasonic waves to the connector frame and then receiving the reflected ultrasonic waves. The time t between transmission and reception is calculated, and the test distance M = C is calculated. T *t, then determine whether M is twice the distance between the ultrasonic transceiver irradiation end and the top of the connecting frame. If the determination is yes, it means that the ultrasonic transceiver is in a qualified state, and proceed to step three. If the determination is no, stop monitoring.

[0019] Step 3: The moving trolley moves the ultrasonic transceiver to the horizontal i-th point. The horizontal rotation component and the vertical adjustment component work together to align the ultrasonic transceiver with the vertical j-th test block. The temperature sensor monitors the temperature T at the j-th test block at the i-th point, and then converts it to an isothermal environment with a temperature of T. eq The temperature compensation algorithm is used to calculate the temperature of the isothermal environment T. eq The speed of ultrasonic wave propagation C 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,jThe expansion amount D of the boiler at the j-th test block at the i-th point is calculated by the expansion amount algorithm. When the expansion amount D of the boiler at the j-th test block at the i-th point is greater than zero, it indicates that the boiler has deformed. When the expansion amount D of the boiler 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 is conducive to accurate monitoring. Mobile monitoring is adopted, which eliminates the need to deploy multiple ultrasonic transceivers, reduces the cost of use, and reduces the workload of maintenance. Moreover, the ultrasonic transceiver and the boiler adopt non-contact measurement. The high temperature at the outer wall of the boiler causes less damage to the ultrasonic transceiver (35), thus ensuring the accuracy of monitoring.

[0020] Furthermore, the temperature compensation algorithm:

[0021] Teq = T - 0.5ZS 标,i,j ;

[0022] C T =C T0 +K×(Teq-T0);

[0023] Z is the temperature gradient coefficient, C T0 The ultrasonic speed at room temperature; C T Where is the ultrasonic velocity at temperature T, K is the temperature coefficient, which is 0.6 m / s·℃, T is the temperature inside the sealed chamber or the temperature at the j-th test block at the i-th point, and T0 is the ambient temperature, which is 25℃.

[0024] Furthermore, the wind compensation algorithm is calculated as follows:

[0025] C W,i,j =C T +v w,i,j ×cosθ i,j ;

[0026]

[0027] C W,i,j v is the ultrasonic wave propagation velocity at the j-th test block of the i-th point; w,i,j For the j-th test block at the i-th point, θ i,j Let (v) be the angle between the ultrasonic motion trajectory and the wind trajectory at the j-th test block of the i-th point. x,i,j v y,i,j v z,i,j ) for v w,i,j Wind force vector; (a, b, c) is the unit vector of propagation direction.

[0028] Furthermore, the distance between the ultrasonic transceiver and the test block is S. i,j The specific calculations are as follows:

[0029] S i,j=(C W,i,j ×t i,j ) / 2.

[0030] Furthermore, the specific calculation of the inflation amount is as follows:

[0031] D = |S i,j -S 标,i,j |-|δ×sinθ i,j |

[0032] D represents the expansion of the boiler at the j-th test block at the i-th point, and S represents the expansion of the boiler at the j-th test block at the i-th point. 标,i,j Here are the standard values ​​for the ultrasonic transceiver and test block, δ is the allowable error value for boiler expansion, and t is... i,j This represents the time it takes for the ultrasonic wave to travel from transmission to reception.

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

[0034] Before monitoring, the horizontal rotation component of the monitoring unit drives the vertical adjustment component to rotate, which in turn drives the horizontal rotation component to rotate. The vertical adjustment component then drives the ultrasonic transceiver to rotate along the vertical adjustment component. The ultrasonic transceiver rotates until it faces the cleaning component directly. The cleaning component moves to contact the ultrasonic transceiver, cleaning the dust from the surface of the ultrasonic transceiver's irradiation end to prevent dust from affecting its monitoring. After dust removal, the cleaning component separates from the ultrasonic transceiver. The vertical adjustment component then drives the ultrasonic transceiver and the enclosed auxiliary component to rotate vertically downwards. The enclosed auxiliary component and the vertical adjustment component combine to form a closed enclosure. This enclosure prevents airflow from affecting the ultrasonic transceiver calibration. A temperature sensor monitors the temperature T inside the enclosure, and a temperature compensation algorithm calculates the ultrasonic propagation speed C at the current temperature. T The ultrasonic transceiver is activated, emitting ultrasonic waves to the connector frame and then receiving the reflected ultrasonic waves. The time t between transmission and reception is calculated, and the test distance M = C is calculated. T *t, then calculate whether M is twice the distance between the ultrasonic transceiver's irradiation end and the top of the connecting frame. If so, the ultrasonic transceiver is in a qualified state and can be monitored subsequently. If not, the ultrasonic transceiver needs adjustment and cannot be tested subsequently. This achieves self-calibration of the ultrasonic transceiver, which is beneficial for practical use. During monitoring, the moving trolley moves the ultrasonic transceiver to the i-th horizontal point. The horizontal rotation component and the vertical adjustment component work together to move the ultrasonic transceiver to face the j-th vertical test block. The temperature sensor monitors the temperature T at the j-th test block at the i-th point, and then converts it to an isothermal environment with an isothermal environment temperature of T. eq The temperature compensation algorithm is used to calculate the temperature of the isothermal environment T. eq The speed of ultrasonic wave propagation CT 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.

[0050] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0051] The present invention will be further described below with reference to embodiments.

[0052] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0053] Example 1: Please refer to Figures 1-12 A mobile boiler appearance deformation real-time monitoring device, including a mobile trolley 1;

[0054] The top of the mobile trolley 1 is connected in sequence from left to right to a cleaning component 2 for wiping the dust adhering to the monitoring end of the monitoring component 3, a monitoring component 3 for multi-dimensional angle adjustment monitoring and self-calibration, and a wind speed and direction sensor 4 for wind speed and direction testing. The cleaning component 2 has a self-cleaning function.

[0055] The monitoring component 3 includes a horizontal rotation component, a vertical adjustment component, a closed auxiliary component, an ultrasonic transceiver 35, a connecting frame 38, and a test block 312. The horizontal rotation component is connected to the moving trolley 1. The vertical adjustment component is fixedly connected to the top of the output end of the horizontal rotation component. The closed auxiliary component and the ultrasonic transceiver 35 are both fixedly installed on the drive end of the vertical adjustment component. The closed auxiliary component is located outside the ultrasonic transceiver 35. When the closed auxiliary component rotates to the vertical state, the vertical adjustment component and the closed auxiliary component are combined into a closed box, and the ultrasonic transceiver 35 is located inside the ultrasonic transceiver 35. The connecting frame 38 is fixedly installed at the bottom inside the vertical adjustment component. The test block 312 is fixedly installed on the outer wall of the boiler. During monitoring, the test block 312 is set perpendicular to the irradiation end of the ultrasonic transceiver 35. When the ultrasonic transceiver 35 rotates to face the cleaning component 2, the cleaning component 2 moves to contact the irradiation end of the ultrasonic transceiver 35.

[0056] A temperature sensor 5 for detecting ambient temperature is fixedly connected to the top of the enclosed auxiliary component, and the sensing end of the temperature sensor 5 and the transmitting end of the ultrasonic transceiver 35 are arranged in parallel.

[0057] The wind speed and direction sensor 4, temperature sensor 5, and ultrasonic transceiver 35 are electrically connected to the control host of the mobile trolley 1. The control host of the mobile trolley 1 receives the data monitored by the wind speed and direction sensor 4, temperature sensor 5, and ultrasonic transceiver 35 and processes it accordingly.

[0058] Before monitoring, the horizontal rotation component of monitoring component 3 drives the vertical adjustment component to rotate, which in turn drives the horizontal rotation component to rotate. Then, the vertical adjustment component drives the ultrasonic transceiver 35 to rotate along the vertical adjustment component. The ultrasonic transceiver 35 rotates to face the cleaning component 2, and the cleaning component 2 moves to contact the ultrasonic transceiver 35. The cleaning component 2 cleans the dust from the surface of the ultrasonic transceiver 35's irradiation end, preventing dust from affecting the ultrasonic transceiver 35's monitoring. After dust removal, the cleaning component 2 separates from the ultrasonic transceiver 35. The vertical adjustment component then drives the ultrasonic transceiver 35 and the enclosed auxiliary component to rotate vertically downwards. The enclosed auxiliary component and the vertical adjustment component combine to form a closed enclosure. The enclosed enclosure prevents airflow from affecting the calibration of the ultrasonic transceiver 35. The temperature sensor 5 monitors the temperature T inside the enclosed enclosure and calculates the ultrasonic propagation speed C at the current temperature using a temperature compensation algorithm. T The ultrasonic transceiver 35 is activated, emitting ultrasonic waves to the connecting frame 38, and then receiving the reflected ultrasonic waves from the connecting frame 38. The time t between ultrasonic wave transmission and reception is calculated, and the test distance M = C is calculated. T *t, then calculate whether M is twice the distance between the irradiation end of the ultrasonic transceiver 35 and the top of the connecting frame 38. If so, it means that the ultrasonic transceiver 35 is in a qualified state and can be monitored subsequently. If not, it means that the ultrasonic transceiver 35 is in a state that needs adjustment and cannot be tested subsequently. This realizes the self-calibration of the ultrasonic transceiver 35, which is beneficial for practical use. During monitoring, the moving trolley 1 moves the ultrasonic transceiver 35 to the i-th horizontal point. The horizontal rotation component and the vertical adjustment component work together to move the ultrasonic transceiver 35 to face the j-th vertical test block 312. The temperature sensor 5 monitors the temperature T at the j-th test block 312 at the i-th point, and then converts it to an isothermal environment with an isothermal environment temperature of T. eq The temperature compensation algorithm is used to calculate the temperature of the isothermal environment T. eq The speed of ultrasonic wave propagation C T Then, the wind speed and direction sensor 4 detects the wind speed v at the j-th test block 312 of the i-th point. w,i,j Then, the ultrasonic propagation velocity C at the j-th test block 312 of the i-th point is calculated using the wind compensation algorithm. W,i,j Then, the ultrasonic wave reflected back from the connector 38 is received, and the time t from the ultrasonic wave transmission to reception is calculated. i,j Then through t i,j and C W,i,j The distance between the ultrasonic transceiver 35 and the test block 312 was measured, and the distance value between the ultrasonic transceiver 35 and the test block 312 was S. i,j Then S i,jThe expansion amount D of the boiler at the j-th test block 312 at the i-th point is calculated using an expansion amount algorithm. If the expansion amount D at the j-th test block 312 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 312 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 35, reducing operating costs and maintenance workload. Furthermore, the ultrasonic transceiver 35 uses non-contact measurement with the boiler, minimizing damage to the transceiver 35 due to the high temperature on the boiler's outer wall, ensuring monitoring accuracy. The cleaning component 2 cleans the dust from the ultrasonic transceiver 35 and can also perform self-cleaning, reducing dust residue on the cleaning component 2 and facilitating its subsequent use.

[0059] The cleaning component 2 includes a self-cleaning component, a position adjustment component, and a rotating cleaning component. The self-cleaning component and the position adjustment component are fixedly connected to the mobile trolley 1. The self-cleaning component is fixedly connected to the position adjustment component, and the position adjustment component is fixedly connected to the rotating cleaning component. The rotating cleaning component is positioned towards the monitoring component 3.

[0060] The position adjustment assembly includes a support frame 22, an electric cylinder 24, and a connecting plate 212. The support frame 22 is fixedly installed on the mobile trolley 1. The electric cylinder 24 is fixedly installed on the upper end of the support frame 22. The driving end of the electric cylinder 24 is fixedly connected to the connecting plate 212. The connecting plate 212 is fixedly connected to the rotary cleaning assembly.

[0061] The rotary cleaning assembly includes a motor 25, a first gear ring 26, a mounting base 27, a sponge 28, a first pipe 29, a second gear ring 210, and a second pipe 211. The second pipe 211 is fixedly installed in the mounting hole of the connecting plate 212. The end of the second pipe 211 away from the electric cylinder 24 is rotatably connected to the first pipe 29 through a bearing. The end of the first pipe 29 away from the electric cylinder 24 is fixedly connected to the mounting base 27. The end of the mounting base 27 away from the electric cylinder 24 is fixedly connected to the sponge 28. The second gear ring 210 is fixedly installed on the first pipe 29. The motor 25 is fixedly installed on the connecting plate 212. The first gear ring 26 is fixedly installed on the drive end of the motor 25, and the first gear ring 26 and the second gear ring 210 are meshed together. The self-cleaning assembly is movably connected to the mounting base 27 and the second pipe 211.

[0062] The self-cleaning component includes an outer tube 21 and a fan 23. The outer tube 21 is fixedly connected to the support frame 22 and the output end of the fan 23 is fixedly connected to the outer tube 21. The fan 23 is fixedly installed at the bottom of the mobile trolley 1. The inner wall of the outer tube 21 is slidably connected to the outer wall of the second pipe 211. The mounting base 27 has an annular chamber 213 that communicates with the first pipe 29. The mounting base 27 has an air hole 214 at the end of the annular chamber 213 away from the electric cylinder 24.

[0063] Before monitoring, the horizontal rotation component of monitoring component 3 drives the vertical adjustment component to rotate, which in turn drives the horizontal rotation component to rotate. Then, the vertical adjustment component drives the ultrasonic transceiver 35 to rotate along the vertical adjustment component. The ultrasonic transceiver 35 rotates to face the sponge 28 of cleaning component 2. The electric cylinder 24 of cleaning component 2 drives the connecting plate 212 to move, which in turn drives the second pipe 211 to move. The second pipe 211 drives the first pipe 29 to move, and the first pipe 29 drives the sponge 28 to move into contact with the ultrasonic transceiver 35. The motor 25 of cleaning component 2 drives the first gear ring 26 to rotate, which in turn drives the second gear ring 210 to rotate. The second gear ring 210 drives the first pipe 29 to rotate, which in turn drives the mounting base 27 to rotate. The mounting base 27 drives the sponge 28 to rotate. The rotating sponge 28 cleans the dust on the surface of the ultrasonic transceiver 35, preventing the dust from affecting the ultrasonic transceiver 35's monitoring.

[0064] After cleaning, the electric cylinder 24 drives the connecting plate 212 to move, the connecting plate 212 drives the second pipe 211 to move, the second pipe 211 drives the first pipe 29 to move, and the first pipe 29 drives the sponge 28 to move away from the monitoring component 3 and return to its original position.

[0065] After the sponge 28 cleans the dust from the ultrasonic transceiver 35, the fan 23 of the cleaning component 2 draws air into the outer tube 21, and then through the second pipe 211 and the first pipe 29 into the annular chamber 213. The air is then ejected from the vent 214, backwashing the dust inside the sponge 28, thus achieving self-cleaning of the sponge 28, reducing the amount of dust residue on the cleaning component 2, and facilitating the subsequent use of the cleaning component 2.

[0066] The horizontal rotation assembly includes a hollow shaft 32, a third gear ring 39, a fourth gear ring 310, and a second motor 311. The moving trolley 1 is rotatably connected to the hollow shaft 32 via bearings. The second motor 311 is fixedly installed at the bottom of the moving trolley 1. The fourth gear ring 310 is fixedly installed at the drive end of the second motor 311. The second motor 311 is meshed with the third gear ring 39. The bottom of the hollow shaft 32 is fixedly installed in the mounting hole opened in the second motor 311. The top of the hollow shaft 32 is fixedly connected to the vertical adjustment assembly.

[0067] The vertical adjustment assembly includes a housing 31, a first motor 33, and a horizontal shaft 36. The bottom of the housing 31 is fixedly installed on the top of the hollow shaft 32. The first motor 33 is fixedly installed on the upper end of the outer wall of the housing 31. The drive end of the first motor 33 passes through the housing 31 and is fixedly connected to the horizontal shaft 36. A straight groove 37 is opened on the top of the housing 31, and the bottom of the straight groove 37 is located at the lower middle end of the housing 31. The horizontal shaft 36 is fixedly connected to the closed auxiliary assembly.

[0068] The enclosed auxiliary component includes an n-shaped plate 34 and a connecting frame 38. Two sets of connecting frames 38 are symmetrically fixedly installed on the horizontal shaft 36. The outer end of the horizontal shaft 36 is fixedly connected to the inner top of the n-shaped plate 34. The front and rear side walls of the n-shaped plate 34 are in close contact with the inner wall of the box 31. When the n-shaped plate 34 is in a vertical state, the bottom of the n-shaped plate 34 is in close contact with the bottom of the straight groove 37, and the top of the n-shaped plate 34 is flush with the top of the hollow shaft 32.

[0069] Temperature sensor 5 is fixedly installed on the top of the n-shaped plate 34.

[0070] There are gaps between the left and right side walls of the connecting frame 38 and the housing 31 for the cables of the first motor 33, ultrasonic transceiver 35 and temperature sensor 5 to pass through. The bottom of the hollow shaft 32 has a straight hole for the cables of the first motor 33, ultrasonic transceiver 35 and temperature sensor 5 to pass through.

[0071] After dust cleaning, the cleaning component 2 separates from the ultrasonic transceiver 35. The first motor 33 of the vertical adjustment component drives the horizontal shaft 36 to rotate. The horizontal shaft 36 drives the ultrasonic transceiver 35 to rotate vertically downwards and rotates the connecting frame 38 of the enclosed auxiliary component. The connecting frame 38 drives the n-shaped plate 34 to rotate vertically downwards. The n-shaped plate 34 of the enclosed auxiliary component and the housing 31 of the vertical adjustment component combine to form an enclosed housing. The enclosed housing prevents airflow from affecting the calibration of the ultrasonic transceiver 35.
