[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] Example: Figure 1-3 As shown, the utility model provides an online measuring device for the ignition point of coal, comprising an operating table 1, on the upper surface of which two heating plates 11 are slidably mounted, and the sides of the two heating plates 11 close to each other are in movable contact with the outer surface of a container for heating the container; a support plate 2 is fixedly mounted on the side of the operating table 1 for mounting a mounting plate 21 and driving the mounting plate 21 to move, and the mounting plate 21 is slidably mounted on the side of the support plate 2 close to the operating table 1, and a filter 24 is detachably mounted on the side of the mounting plate 21 away from the support plate 2, for filtering dust and harmful gases generated during coal combustion, and the lower surface of the filter 24 is in movable contact with the upper surface of the container.

[0019] Two sliders 12 are fixedly installed on the lower surface of the heating plate 11, and the sliders 12 are slidably arranged inside the operating table 1. Two bidirectional screws 13 are rotatably installed inside the operating table 1, and the two sliders 12 are threadedly connected to the bidirectional screws 13 to drive the heating plate 11 to move. When in use, the rotation of the bidirectional screws 13 drives the sliders 12 to move, and the movement of the sliders 12 drives the heating plate 11 to move.

[0020] By adopting the above technical solution, the bidirectional screw 13 can drive the heating plate 11 to move.

[0021] A rotating rod 15 is rotatably installed on one side of the operating table 1, and two second bevel gears 16 are fixedly installed on the outer surface of the rotating rod 15. A first bevel gear 14 is fixedly installed on one end of the bidirectional screw 13 close to the rotating rod 15, and the first bevel gear 14 and the second bevel gear 16 are engaged with each other to drive the bidirectional screw 13 to rotate. When in use, the rotating rod 15 drives the second bevel gear 16 to rotate, and the rotation of the second bevel gear 16 drives the first bevel gear 14 to rotate, and the rotation of the first bevel gear 14 drives the bidirectional screw 13 to rotate.

[0022] By adopting the above technical solution, the rotating rod 15 drives the bidirectional screw 13 to rotate.

[0023] Two clamping plates 26 are installed on the side of the mounting plate 21 for sliding away from the support plate 2. A connecting block 25 is fixedly installed on the outer surface of the filter 24, and the ends of the clamping plates 26 that are close to each other are movably inserted into the connecting block 25 to limit the filter 24. During use, when the ends of the clamping plates 26 that are close to each other are inserted into the connecting block 25, the filter 24 cannot move, thereby limiting the filter 24.

[0024] By adopting the above technical solution, the clamping plate 26 can limit the filter 24.

[0025] A moving block 27 is fixedly installed on the side of the splint 26 away from the filter 24, and the moving block 27 is slidably set inside the mounting plate 21 to limit the splint 26. When in use, two moving grooves are opened in the mounting plate 21, and the moving block 27 is slidably set inside the moving grooves, so that the splint 26 can only move along the moving grooves.

[0026] By adopting the above technical solution, the moving block 27 can limit the clamping plate 26.

[0027] A double-headed screw 28 is rotatably installed in the mounting plate 21, and two moving blocks 27 are threadedly connected to the double-headed screw 28 to drive the splint 26 to move. When in use, the double-headed screw 28 is rotated to drive the moving block 27 to move, and the movement of the moving block 27 drives the splint 26 to move.

[0028] By adopting the above technical solution, the double-headed screw 28 can drive the clamping plate 26 to move.

[0029] A limit block 22 is fixedly installed on the side of the mounting plate 21 away from the filter 24, and the limit block 22 is slidably arranged inside the support plate 2. An electric cylinder 23 is fixedly installed on the upper surface of the support plate 2, and the bottom end of the output shaft of the electric cylinder 23 is fixedly connected to the limit block 22 to drive the mounting plate 21 to move. When in use, the electric cylinder 23 is turned on to drive the limit block 22 to move, and the movement of the limit block 22 drives the mounting plate 21 to move.

[0030] By adopting the above technical solution, the electric cylinder 23 can drive the mounting plate 21 to move.

[0031] A storage box 3 is fixedly installed on the side of the support plate 2 away from the operating table 1, which is used to store the fire extinguishing liquid. A transport pump 31 is fixedly installed in the storage box 3. Two connecting pipes 32 are fixedly installed on the upper surface of the transport pump 31, and one end of the connecting pipe 32 away from the transport pump 31 is movably installed on the filter 24, so that the transport pump 31 can transport the liquid. When in use, the transport pump 31 is turned on to allow water to be transported to the inside of the filter 24 through the connecting pipe 32 and flow into the container through the holes in the filter 24.

[0032] By adopting the above technical solution, the transport pump 31 can transport the liquid.

[0033] Working principle: First, place the container containing the sample on the operating table 1, rotate the rotating rod 15 to drive the second bevel gear 16 to rotate, and the rotation of the second bevel gear 16 drives the first bevel gear 14 to rotate, and the rotation of the first bevel gear 14 drives the bidirectional screw 13 to rotate, and the rotation of the bidirectional screw 13 drives the slider 12 to move, and the movement of the slider 12 drives the heating plate 11 to move, so that the sides of the heating plate 11 that are close to each other contact the outer surface of the container;

[0034] Next, the electric cylinder 23 is turned on to drive the limit block 22 to move, and the movement of the limit block 22 drives the mounting plate 21 to move, and the movement of the mounting plate 21 drives the filter 24 to move, so that the lower surface of the filter 24 contacts the upper surface of the container;

[0035] The container is then heated by the heating plate 11. As the temperature rises, the coal will spontaneously combust, thereby measuring the ignition point of the coal. When the coal spontaneously combusts, the dust and harmful gases generated by the spontaneous combustion of the coal are filtered through the filter 24. At the same time, the transport pump 31 is turned on to transport water into the filter 24 through the connecting pipe 32, and then flow into the container through the holes of the filter 24 to extinguish the fire.

[0036] Finally, when the filter 24 needs to be replaced, the connecting pipe 32 is removed from the filter 24, and then the double-headed screw 28 is rotated to drive the moving block 27 to move. The movement of the moving block 27 drives the splint 26 to move, so that the ends of the splints 26 that are close to each other are separated from the inside of the connecting block 25, completing the disassembly of the filter 24, thereby replacing the filter 24.

[0037] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
