The setting of the driving guide rollers 7 facilitates the smooth sliding of the industrial furnace placed above it. A support plate 10 is fixed above the testing platform 1, and a folding block 11 is slidably installed on the side of the support plate 10. The CCD camera 3 is fixed at the end of the folding block 11. A pushing unit 8 for controlling the CCD camera 3 to automatically move downward for taking pictures is arranged between the testing platform 1 and the frame 2. A lens dust removal unit 9 is arranged on the support plate 10, and the lens dust removal unit 9 cooperates with the pushing unit 8 to realize automatic dust removal operation on the lens of the CCD camera 3.

[0027] In this embodiment, the pushing unit 8 includes a contact triangle block 81 slidably mounted above the strip guide rail 5, a spring block 82 is fixed in front of the contact triangle block 81, and a reset spring 83 is fixed between the spring block 82 and the strip guide rail 5.

An eccentric wheel 97 is fixed on the surface of the rear rotating rod 95. The diameter of the large gear 94 is larger than the diameter of the small gear 96. In this embodiment, the diameter ratio of the large gear 94 to the small gear 96 is preferably five to one. The diameter ratio is used to achieve accelerated rotation of the small gear 96, thereby driving the eccentric wheel 97 to accelerate rotation. A dust removal cylinder 98 is fixed on the side of the support plate 10, and a dynamic The power piston 99 and the ash removal cylinder 98 are fixed with a protrusion 910 on the inner wall, and a power spring 911 is fixed between the protrusion 910 and the power piston 99. The setting of the power spring 911 facilitates the rapid reset of the power piston 99 after moving downward, and ensures that the power rod 918 can always be in contact with the surface of the eccentric wheel 97. There are two groups of protrusions 910 and power springs 911. A delivery pipe 912 is connected to the bottom of the ash removal cylinder 98, a nozzle 913 is fixed to the bottom of the folding block 11, and an inclined booster nozzle 914 is connected and fixed to the end of the nozzle 913.

A power rod 918 is fixed above the power piston 99. The air delivery valve 915 and the air intake valve 917 are both one-way valves. The air delivery valve 915 is used to unidirectionally deliver the air in the delivery pipe 912 to the nozzle 913, and the air intake valve 917 is used to deliver external air to the air intake pipe 916.

[0029] In this embodiment, the contact triangle block 81 is a right-angle triangle block, and the left side of the contact triangle block 81 is designed as a slope, so that when the industrial furnace slides and moves, the contact triangle block 81 can be smoothly squeezed, and the subsequent components are driven to move through the contact triangle block 81.

[0030] In this embodiment, the pushing triangle block 811 also adopts a right-angle triangle block, and the bottom of the pushing triangle block 811 is designed with an inclined surface. The inclined surface of the pushing triangle block 811 can squeeze the CCD camera 3, so that the CCD camera 3 can move downward smoothly.

[0031] In the present embodiment, a limit baffle 13 is rotatably installed on the top of the strip guide rail 5 through a pin shaft 12, and a buffer rubber pad 14 is fixed to the side of the limit baffle 13. The entire limit baffle 13 can be rotated by the pin shaft 12, and the limit baffle 13 loses its blocking of the industrial furnace, thereby facilitating the pushing out of the inspected industrial furnace. The buffer rubber pad 14 is used to buffer and block the industrial furnace to avoid direct contact between the industrial furnace and the limit baffle 13 due to inertia, thereby effectively protecting the industrial furnace.

[0032] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0033] During operation, the small industrial furnace to be inspected is placed between the two inclined guide rails 6. Under the action of gravity, the driving guide roller 7 drives the entire small industrial furnace to slide down smoothly. During the sliding process, the contact triangle block 81 is squeezed, so that the contact triangle block 81 moves forward, and then the entire rotating bar 86 is driven to rotate counterclockwise (left view) through the lower pull rod 87. The entire pushing triangle block 811 is driven to move backward through the upper pull rod 88 and the sliding bar 810. The CCD camera 3 is squeezed by the pushing triangle block 811, and the entire CCD camera 3 is driven downward with the cooperation of the folding block 11. When the small industrial furnace is blocked by the limit baffle 13, the pushing triangle block 811 is squeezed to the maximum displacement, and the folding block 11 moves downward to contact the trigger switch 815, and then the small industrial furnace is blocked by the limit baffle 13. The CCD camera 3 is controlled to start taking pictures. During the upward and downward movement of the folding block 11, the large gear 94 is driven to rotate through the linkage rack 91, and then the small gear 96 is driven to rotate faster by utilizing the different gear diameter ratios, so that the eccentric wheel 97 can rotate faster, and cooperate with the power spring 911 to drive the entire power piston 99 to move up and down quickly. When the power piston 99 moves up, external air enters the dust removal cylinder 98. When the power piston 99 moves down, the air in the dust removal cylinder 98 is quickly pressed out into the nozzle 913 and quickly sprayed onto the lens on the CCD camera 3 through the inclined booster nozzle 914, so that the dust can be quickly blown away before taking pictures, and the inertia of the small industrial furnace when sliding is used to provide power to realize the detection and dust removal operations.
