[0025] Embodiment 1; Please refer to Figures 1 to 5, the present utility model provides a technical solution: a temperature detection device for recovering waste heat from boiler wastewater. The temperature detection device includes: a temperature detector 1, a temperature probe 2 is installed at the bottom of the temperature detector 1, a lower moisture-proof shell 3 is installed at the bottom of the outer surface of the temperature detector 1, an upper moisture-proof shell 4 is installed at the top of the outer surface of the temperature detector 1, a moisture-proof hopper 5 is installed at the bottom of the lower moisture-proof shell 3, and the moisture-proof hopper 5 is located on the outer surface of the temperature probe 2;

[0026] Fixed blocks 10 are installed on the side walls of the upper moisture-proof shell 4, clamping members 16 are installed on both sides of the fixed blocks 10, a placement block 6 is installed on the side wall of the lower moisture-proof shell 3, a lead screw 9 is installed through the top of the placement block 6, and the top of the lead screw 9 is fixed to the bottom of the fixed block 10;

[0027] During use, the temperature probe 2 at the bottom of the temperature detector 1 is passed through the moisture-proof hopper 5 and placed inside the lower moisture-proof shell 3. The upper moisture-proof shell 4 is driven to move by the lead screw 9, and the upper moisture-proof shell 4 and the lower moisture-proof shell 3 are used to cover and clamp the temperature detector 1 through the clamping members 16, so as to prevent the temperature detector 1 from being affected by water droplets condensed from water vapor hanging on the temperature detector 1 during detection, and at the same time prevent water vapor from eroding the internal parts of the temperature detector 1, affecting the sensitivity, accuracy and service life of the temperature detector 1.

[0028] Embodiment 2; On the basis of Embodiment 1, a structure for rapid heat dissipation is provided. Ventilation slots 11 are opened on the side walls of the lower moisture-proof shell 3 and the upper moisture-proof shell 4. A dust-proof net 12 is installed inside the ventilation slots 11. Jack holes 13 are opened at the bottom of the ventilation slots 11. A baffle 14 is installed at the top of the ventilation slots 11. A rotating block 15 is installed at the bottom of the baffle 14, and the rotating block 15 is movably placed inside the jack hole 13;

[0029] During use, the sensitivity and result of detection are prevented from being affected by excessive temperature inside the temperature detector 1 through the ventilation slots 11. When dissipating heat, the rotating block 15 drives the baffle 14 to rotate, so that the internal air circulates quickly and the hot air can be quickly dissipated. At the same time, the dust-proof net 12 prevents dust from entering the inside of the temperature detector 1.

[0030] Embodiment 3; On the basis of Embodiment 2, a structure for convenient installation and fixation is provided. A placement groove 7 is opened on the side wall of the placement block 6, a fixing component 8 is installed inside the placement groove 7, the fixing component 8 includes a movable block 17, the movable block 17 is located inside the placement groove 7, a movable bolt 18 is installed on the side wall of the movable block 17, clamping blocks 19 are installed at both ends of the movable bolt 18, and grooves 20 are opened on the side walls of the clamping blocks 19;

[0031] During use, the clamping blocks 19 are clamped at the detection point inside the boiler through the grooves 20. During the installation process, the movable block 17 moves towards the inside of the placement groove 7, so that the side wall of the placement groove 7 clamps the clamping blocks 19 to prevent them from falling off.

[0032] Working principle: In actual use, the temperature probe 2 at the bottom of the temperature detector 1 passes through the moisture-proof hopper 5 and is placed inside the lower moisture-proof shell 3. The upper moisture-proof shell 4 is driven to move by the lead screw 9. The upper moisture-proof shell 4 and the lower moisture-proof shell 3 cover and clamp the temperature detector 1 through the clamping member 16. The clamping block 19 is clamped at the detection point inside the boiler through the groove 20. During the installation process, the movable block 17 moves into the placement groove 7, so that the side wall of the placement groove 7 clamps the clamping block 19 to prevent it from falling. The air permeability groove 11 is used to prevent the temperature inside the temperature detector 1 from being too high, which affects the detection sensitivity and results. When dissipating heat, the rotating block 15 drives the baffle 14 to rotate, so that the air inside circulates quickly and the hot air can be quickly dissipated. At the same time, the dust-proof net 12 prevents dust from entering the inside of the temperature detector 1. In this way, it is avoided that when detecting, the temperature detector 1 is affected by the water vapor condensing into water droplets hanging on the temperature detector 1, which affects the detection result. At the same time, it is avoided that the water vapor will corrode the internal parts of the temperature detector 1, affecting the sensitivity, accuracy and service life of the temperature detector 1.
