[0002] The carbon analyzer is a carbon analyzer that measures carbon emissions. It can detect five elements, namely carbon, hydrogen, oxygen, nitrogen and sulfur, in all organic substances. The main gas emissions from thermal power plants are sulfur dioxide, nitrogen oxides, carbon dioxide, and carbon monoxide produced by incomplete combustion. The carbon dioxide emitted by thermal power plants easily absorbs electromagnetic waves with longer wavelengths, so that the electromagnetic waves reflected by the earth are reabsorbed, resulting in heat that cannot be dissipated, forming a greenhouse effect. The emitted carbon monoxide may cause chronic bronchitis, obstructive pulmonary emphysema and other diseases in the human body, so a carbon analyzer is needed for detection.
[0003] When the measuring instrument detects gases such as carbon dioxide and carbon monoxide emitted from thermal power plants, it is necessary to connect the ventilation pipe to the pump suction interface, extend the probe rod to the detection point and press the control button to operate. When the measuring instrument fails, it is necessary to remove the fastening bolts of the measuring instrument and then open the upper and lower covers of the measuring instrument to inspect and maintain the internal parts of the measuring instrument. Since the gap between the upper and lower covers of the measuring instrument is small, maintenance personnel need to carefully use tools to pry open the upper and lower covers, which takes a certain amount of time and is not convenient for maintenance personnel to inspect and maintain the internal parts of the measuring instrument.

DETAILED DESCRIPTION
[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] See also Figure 1-Figure 4 The utility model provides a technical solution: a measuring instrument convenient for internal maintenance, comprising an upper cover plate 1 of the measuring instrument and a lower cover plate 11 of the measuring instrument, the lower side of the upper cover plate 1 of the measuring instrument is docked with the lower cover plate 11 of the measuring instrument, and the upper side of the upper cover plate 1 of the measuring instrument is docked with a control button 12 and a display panel 13, respectively, the upper cover plate 1 of the measuring instrument is connected to a fixed cover 2 on both sides of the control button 12 and the display panel 13, a toothed belt 21 is arranged inside the fixed cover 2, and the convex tooth block in the middle of the toothed belt 21 is connected to the convex tooth block of the first gear 22, and the first gear 22 is movably connected to the fixed cover 2 through a bearing, and both ends of the toothed belt 21 are connected to the convex tooth block of the first gear 22. The convex tooth blocks are respectively connected with the convex tooth blocks of the second gear 23, and the second gear 23 is movably connected with the fixed cover 2 through a bearing. The fixed cover 2 is provided with a slide groove 24 above the second gear 23, and the slide groove 24 is slidably connected with the upper end of the docking screw 25, and the lower end of the docking screw 25 extends through the interior of the second gear 23. A docking screw 25 is fixed on the upper side of the first gear 22, and the toothed belt 21 is meshed and connected with the first gear 22 and the second gear 23 respectively. The second gear 23 is threadedly connected to the docking screw 25. The cross-sectional shape of the slide groove 24 is rectangular, and the slide groove 24 matches the connecting block at the upper end of the docking screw 25.
[0022] In specific implementation, when the measuring instrument detects gases such as carbon dioxide and carbon monoxide emitted from a thermal power plant, it is necessary to connect the ventilation pipe to the pump suction interface, extend the probe rod to the detection point, and press the control button 12 to operate. When the measuring instrument fails, first remove the fastening bolts of the measuring instrument, and then rotate the two knobs 26 at the same time, so that the knob 26 drives the first gear 22 to rotate, and the toothed belt 21 is meshed with the first gear 22, so that the first gear 22 drives the toothed belt 21 to rotate. Since the toothed belt 21 is also meshed with the second gear 23, the second gear 23 rotates with the toothed belt 21, and the second gear 23 rotates with the toothed belt 21. The second gear 23 is threadedly connected to the docking screw 25, and the cross-sectional shape of the slide groove 24 is rectangular. The slide groove 24 matches the connecting block at the upper end of the docking screw 25. The slide groove 24 limits the docking screw 25 to rotate along the second gear 23, so that the docking screw 25 can be telescopically moved along the slide groove 24. When the docking screw 25 moves down along the slide groove 24, the docking screw 25 squeezes the lower cover plate 11 of the measuring instrument, thereby increasing the gap between the upper cover plate 1 of the measuring instrument and the lower cover plate 11 of the measuring instrument, so that maintenance personnel do not need to use tools to pry open the upper and lower covers of the measuring instrument when inspecting the measuring instrument, making the measuring instrument easy to carry out internal inspection and maintenance.
[0023] A fixing ring 3 is connected to one side of the lower cover 11 of the measuring instrument, and a connecting rope 4 runs through the interior of the fixing ring 3. One end of the connecting rope 4 is fixed to the connecting ring 5. The connecting rope 4 is made of nylon rope, and the connecting ring 5 is made of elastic rubber band material.
[0024] In specific implementation, when the staff holds the measuring instrument to detect gases such as carbon dioxide and carbon monoxide emitted from the thermal power plant, they pass their wrists through the connecting ring 5. The connecting ring 5 is made of elastic rubber band material with excellent elasticity, so that the connecting ring 5 can adapt to the wrists of most people. When the staff accidentally drops the measuring instrument due to slipping, the connecting ring 5 worn on the wrist is pulled by the connecting rope 4, so that the measuring instrument will not fall directly to the ground. The connecting rope 4 is made of nylon rope with good wear resistance and fatigue resistance, so that the connecting rope 4 is not easy to be broken, thereby ensuring the safety of the measuring instrument when the staff holds the measuring instrument for detection.
[0025] To sum up, when the measuring instrument detects gases such as carbon dioxide and carbon monoxide emitted by thermal power plants, it is necessary to connect the ventilation pipe to the pump suction interface, extend the probe to the detection point and press the control button 12 to operate. When the measuring instrument fails, first remove the fastening bolts of the measuring instrument, and then rotate the two knobs 26 at the same time to move the docking screw 25 down along the slide groove 24. The docking screw 25 squeezes the lower cover plate 11 of the measuring instrument, so that the gap between the upper cover plate 1 of the measuring instrument and the lower cover plate 11 of the measuring instrument is increased, so that the measuring instrument is convenient for internal inspection and maintenance. When the staff holds the measuring instrument to detect gases such as carbon dioxide and carbon monoxide emitted by thermal power plants, they pass their wrists through the connecting ring 5. When the staff accidentally drops the measuring instrument by slipping, the connecting ring 5 worn on the wrist is pulled by the connecting rope 4, so that the measuring instrument will not fall directly to the ground, thereby ensuring the safety of the measuring instrument when the staff holds the measuring instrument for detection.
