[0029] See also Figure 1 The present application provides a heated surface monitoring device, comprising: a motor, a lead screw 4 and a monitoring component 7. The motor is connected to the lead screw 4 and is used to drive the lead screw 4 to perform reciprocating motion. The lead screw 4 is connected to the monitoring component 7.

[0030] In the technical solution provided in the embodiment of the present application, the power output end of the motor is connected to the screw 4, driving the screw 4 to reciprocate, and the monitoring component 7 connected to the screw 4 can also reciprocate accordingly. During the reciprocating motion, the monitoring range of the monitoring component 7 is correspondingly increased, and can cover a wider range of monitoring areas, reducing or even avoiding the generation of monitoring blind spots, and effectively optimizing the monitoring effect of the heated surface monitoring device. The heated surface monitoring device provided in the embodiment of the present application solves the technical defects of the prior art, such as poor monitoring effect of heated surfaces and the susceptibility to monitoring blind spots.

[0031] A heated surface monitoring device provided in an embodiment of the present application further includes an electric push rod 6, which is respectively connected to the lead screw 4 and the monitoring assembly 7. By respectively connecting the lead screw 4 and the monitoring assembly 7 through the electric push rod 6, the power from the lead screw 4 can be transmitted to the monitoring assembly 7 more smoothly. At the same time, it also plays a certain supporting role for the monitoring assembly 7, effectively improving the movement stability of the monitoring assembly 7 during the reciprocating motion to monitor the heated surface. In particular, considering the working environment of the heated surface monitoring device, especially the working environment of the monitoring assembly 7 is in a high-temperature environment, which may have a certain impact on the stability of various structures, the power transmission through the electric push rod 6 effectively improves the stability of the reciprocating motion of the monitoring assembly 7, thereby improving the working stability and reliability of the heated surface monitoring device.

[0032] To further optimize the technical solution, the heated surface monitoring device further includes a slide 5, an electric push rod 6 mounted on the upper surface of the slide 5, and the slide 5 is connected to the lead screw 4. The lead screw 4 drives the slide 5 to move, and the slide 5 provides effective support for the electric push rod 6, further improving the stability of the reciprocating motion of the monitoring component 7.

[0033] In actual application, in order to prevent the lead screw 4 from deviating from the normal movement path during the reciprocating motion, a limit plate 8 can be added to limit and block the movement of the slide 5.

[0034] See further here Figure 3 During operation of the heated surface monitoring device, the operating environment temperature of the monitoring assembly 7 is relatively high. Since heat conduction may occur between the components connecting the monitoring assembly 7 and the motor, the temperature of the monitoring assembly 7 may be transferred to the motor, causing damage to the motor. The heated surface monitoring device provided in this embodiment of the application further includes: an insulation frame 3, with the lead screw 4 passing through both ends of the insulation frame 3. The insulation frame 3 acts as a heat barrier, blocking the heat conduction from the monitoring assembly 7. This not only prevents damage to the motor caused by overheating, but also avoids heat loss and waste due to heat conduction.

[0035] In order to better protect the monitoring component 7 and the electric push rod 6 and effectively avoid damage to them by the high temperature in the furnace, the heating surface monitoring device provided in the embodiment of the present application includes: a shielding component, which includes two heat insulation covers 10 with openings on the lower surface and the side surfaces. The heat insulation covers 10 shield and protect the electric push rod 6 and the monitoring component 7. The two heat insulation covers 10 are both installed with a fixing plate 12 on the opposite side. The fixing plate 12 fixes the mounting rod 11. The mounting rod 11 is installed through the fixing plate 12. The mounting rod 11 drives the heat insulation cover 10 to Move, one end of the mounting rod 11 extends through the boiler body 1, the lower surface of the heat insulation cover 10 is fitted with the upper surface of the heat insulation frame 3, and by setting the heat insulation cover 10, the monitoring component 7 and the electric push rod 6 are wrapped and isolated by utilizing the function of the heat insulation cover 10, and the monitoring component 7 and the electric push rod 6 are further protected to avoid the monitoring component 7 and the electric push rod 6 being exposed to high temperature damage in the boiler body 1. Combined with the function of the mounting rod 11 and the fixing plate 12, it is convenient to operate the heat insulation cover 10 through the mounting rod 11, thereby increasing the scope of use.

[0036] To further optimize the technical solution and expand the monitoring range of the monitoring assembly 7, in the technical solution provided in the embodiment of the present application, the lead screw 4 rotates around the insulation frame 3. During the rotation of the lead screw 4 around the insulation frame 3, the monitoring assembly 7 can be driven to rotate synchronously. During the rotation, the movement range of the monitoring assembly 7 can be further expanded, thereby effectively increasing the monitoring area of ​​the monitoring assembly 7.

[0037] To further optimize the technical solution, and to facilitate the operator to read the monitoring data of the monitoring assembly 7 and make subsequent adjustments based on the real-time data, the heated surface monitoring device provided in the embodiment of the present application further includes a display panel 29, which is electrically connected to the monitoring assembly 7. The operator can read the monitoring data from the monitoring assembly 7 in real time through the display panel 29, further optimizing the ease of use of the heated surface monitoring device.

[0039] The shielding assembly includes two heat insulation covers 10 with openings on the lower surface and side surfaces. The heat insulation covers 10 shield and protect the electric push rod 6 and the monitoring assembly 7. The two heat insulation covers 10 are each installed with a fixing plate 12 on the opposite side. The fixing plate 12 fixes the mounting rod 11. The mounting rod 11 is installed through the fixing plate 12. The mounting rod 11 drives the heat insulation cover 10 to move. One end of the mounting rod 11 extends through the boiler body 1. The lower surface of the heat insulation cover 10 is in contact with the upper surface of the insulation frame 3. By setting the heat insulation cover 10, the function of the heat insulation cover 10 is utilized to wrap and isolate the monitoring assembly 7 and the electric push rod 6, and further protect the monitoring assembly 7 and the electric push rod 6 to avoid being exposed to high temperature damage in the boiler body 1. Combined with the function of the mounting rod 11 and the fixing plate 12, it is convenient to operate the heat insulation cover 10 through the mounting rod 11, thereby increasing the scope of use.

[0040] In the boiler provided in the embodiment of the present application, the motor is arranged on the outside of the boiler body 1, and the monitoring component 7 is arranged on the inside of the boiler body 1. The motor drives the screw 4 to perform reciprocating motion, and the monitoring component 7 can move accordingly inside the boiler body 1, so that the monitoring component 7 can monitor the temperature inside the boiler body 1 at multiple locations, avoiding the phenomenon of temperature measurement blind spots.

[0041] The boiler provided in the embodiment of the present application further includes a controller electrically connected to the monitoring assembly 7 and disposed outside the boiler body 1. The controller reads the monitoring data from the monitoring assembly 7 and issues corresponding instructions to the boiler, thereby avoiding problems such as low boiler efficiency due to low temperatures or poor boiler safety due to high temperatures, thereby ensuring safe and efficient operation of the boiler.

By providing the return pipe 25 and the heat dissipation tube, and utilizing the function of the return pipe 25 being connected to one end of the cooling tube, when water enters the cooling tube, after cooling, the temperature of the water in the cooling tube increases, and then it returns to the water tank again through the return pipe 25, so that the water in the water tank can be refluxed and reused, saving water resources and convenient operation. Combined with the function of the heat dissipation tube, the water in the return pipe 25 is promptly dissipated faster, thereby improving the heat dissipation efficiency and speed.
