Abstract
Description
Technical Field
[0001] This invention relates to the field of pulverized coal concentration measuring equipment, specifically a boiler pulverized coal concentration measuring device. Background Technology
[0002] The pulverized coal concentration detector is an instrument that uses the infrared light absorption method to measure the concentration of airborne dust in the environment. It can accurately and timely reflect the quality of respirable dust inhaled by personnel exposed to dust and the dust pollution status in different dusty workplaces. It provides reliable data for accurately evaluating the hygiene status of the workplace. This equipment is even more important in boiler rooms. The pulverized coal concentration detector can measure the concentration of airborne dust to prevent excessive dust inhalation from harming the human body due to excessive concentration, and also prevent the danger of dust explosion caused by excessive dust concentration.
[0003] However, existing boiler pulverized coal concentration detectors typically rely on traditional supports or two sets of interlocking supports with screws inserted into multiple screw holes to adjust the height of the support when the ground is uneven or wet. This method is cumbersome and can cause the support force to be dispersed, leading to instability and potential breakage due to insufficient support. This can damage the instrument, rendering it unusable and unable to accurately detect the concentration of dust in the air. Furthermore, it poses a safety hazard to workers during operation. Therefore, there is an urgent need to design a boiler pulverized coal concentration measuring device to solve these problems. Summary of the Invention

[0017] 2. This boiler pulverized coal concentration measuring device works by inserting the top of the support rod into the bracket interface. The two sides of the support rod surface abut against the second limiting block, causing it to retract into the first limiting block. Then, the support rod surface abuts against one side of the first limiting block, causing it to retract into the groove opened in the bracket interface. After the top of the support rod enters the bracket interface, the second telescopic rod supports the first limiting block into the limiting grooves opened on both sides of the top of the support rod. Simultaneously, the third telescopic rod supports the second limiting block, which is inserted into the slot opened in the bracket interface, thus fixing the position of the support frame. During disassembly, pulling the connecting rod causes the fixing pile to retract the second and third telescopic rods, thereby disengaging the second and first limiting blocks from the support rod, achieving disassembly of the support rod. This makes installation and disassembly more convenient without affecting its overall stability. Attached Figure Description

[0034] Furthermore, slots are provided on both sides of the bracket interface 14.

[0035] Furthermore, an L-shaped through hole is provided on one side of the first limiting block 35, and one end of the third telescopic rod 36 is fixedly connected to one side of the inner wall of the L-shaped through hole provided in the first limiting block 35.

[0036] Working principle: In use, the control lever 21 is rotated to drive the gear 22, which is fixedly connected at one end, to rotate in the tooth groove of the support frame 16. This causes the bearing base 23, which is fixedly connected to one side of the gear 22, to rotate, thus supporting the gear 22 without affecting its rotation. When the gear 22 rotates, it drives the fixed block 24, which is fixedly connected to the surface of the fixed rod, to adjust its angle. This allows the hinge block 25 inserted inside the fixed block 24 to adjust the height of one side of the support plate 26. The slider 27, which is fixedly connected to the other side of the support plate 26, moves in the groove of the support frame 16 under the support of the first telescopic rod 28, keeping the support plate 26 parallel. This allows the support plate 26 to stably support the support rod 15, which is abutting the surface, and adjust its height, thereby achieving a stable adjustment of the height of the instrument body 11.
[0037] In use, when the top end of the support rod 15 is first inserted into the bracket interface 14, the two sides of the surface of the support rod 15 abut against the second limiting block 37, causing it to press against the third telescopic rod 36, thereby retracting into the first limiting block 35. Then, the surface of the support rod 15 abuts against one side of the first limiting block 35, causing it to press against the second telescopic rod 34, causing it to retract into the groove opened in the bracket interface 14. After the top end of the support rod 15 enters the bracket interface 14, the second telescopic rod 34 supports the first limiting block 35 into the limiting groove opened on both sides of the top end of the support rod 15. At the same time, the third telescopic rod 36... The second limiting block 37 is inserted into the slot of the bracket interface 14 to fix the position of the support frame 16. When disassembling, pulling the connecting rod 31 causes the fixing pile 32 to move the first hinge rod 33 and the second hinge rod 38 inside it to adjust the angle. When the angle is adjusted to the limit, the second telescopic rod 34 and the third telescopic rod 36 retract, thereby causing the second limiting block 37 and the first limiting block 35 to disengage from the support rod 15, realizing the disassembly of the support rod 15. This makes the installation and disassembly operation more convenient without affecting its overall stability.
