Description

Technical Field

[0001] This utility model belongs to the technical field of flue gas monitoring equipment, and in particular relates to a high-concentration flue gas detection device. Background Technology

[0002] High-concentration flue gas detectors are specialized equipment used in industrial settings to accurately measure high-concentration flue gas pollutants such as particulate matter (dust), SO, NO, CO, and VOCs, as well as parameters such as temperature, pressure, flow rate, and moisture content. The core technology utilizes β-ray, laser scattering, ultraviolet fluorescence, NDIR infrared, and PID photoionization. It features wide measurement range adaptability (0-10000ppm+ for gaseous state, 0-50000mg / m³+ for particulate matter), temperature and corrosion resistance (temperature resistance ≤800℃, compatible with PTFE / Hastelloy alloy materials), and accuracy compliance (compliant with GB / T 16157 and HJ / T 76 standards). It is available in portable (for rapid on-site detection and emergency investigation) and online (for 24-hour continuous monitoring and environmental data upload).

[0003] Because the write-type high-concentration flue gas detector is significantly larger than the average person's hand, it can only be held with difficulty. Compared to conventional write-type devices, it is more likely to slip off the hand, thus causing the problem of conventional write-type high-concentration flue gas detectors being prone to slippage.

[0004] Therefore, we propose a high-concentration flue gas detection device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the problem of easy slippage in conventional high-concentration flue gas detectors, and to propose a high-concentration flue gas detection device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A high-concentration flue gas detection device includes a flue gas detector. The lower end of the detector is equipped with a fixing sleeve and a first bolt. An elastic band is fitted inside the fixing sleeve. The first bolt passes through the fixing sleeve and is threaded onto the lower part of the detector. One end of the elastic band is fixedly connected to a cloth strip. A second bolt is movably inserted inside the cloth strip, and a nut is threaded onto the second bolt. A pressure plate is slidably fitted outside the second bolt, and the pressure plate is fitted over the cloth strip. By placing a hand between the detector and the elastic band, the elastic band presses against the back of the hand, keeping the hand pressed against the detector and preventing it from slipping. Loosening the nut allows pulling the cloth strip outwards to tighten the elastic band, and vice versa. Tightening the nut secures the cloth strip, allowing for stable adjustment. By adjusting the position of the cloth strip, the tightness of the elastic band can be easily adjusted, preventing slippage and allowing for easy adjustment of the elasticity to match the thickness of the worker's hand.

[0007] Preferably, the second bolt includes a threaded bolt body, the upper end of which is fixedly connected to the flue gas detector, and a limiting groove is formed on the side of the threaded bolt body. The limiting groove restricts the rotation of the pressure plate, and the threaded bolt body guides the screw thread of the nut.

[0008] Preferably, the pressure plate includes a plate body with a first through hole cut into its interior. The threaded bolt is inserted into the first through hole, and a stop strip is fixedly connected to the side of the plate body. By using the plate body and the stop strip to cover the fabric tape, the stability of the relative position between the pressure plate and the fabric tape is increased.

[0009] Preferably, the nut includes a nut body, and a knob is fixedly connected to the lower part of the nut body. The nut body is threadedly mounted on a threaded bolt body, and the nut body contacts the plate. Turning the knob acts on the nut body, causing the nut body to spirally press the pressure plate or loosen the pressure plate along the threaded bolt body, facilitating the loosening or tightening of the pressure plate on the fabric tape.

[0010] Preferably, the tape includes a tape body, a first fabric ring fixedly connected to the lower end of the tape body, a second fabric ring fixedly connected to the other end of the tape body, a threaded bolt movably inserted into the tape body, and a plate and a stop strip sleeved on the tape body. Tightening the nut causes the pressure plate to press and fix the tape body, and vice versa, the pressure plate releases the tape body.

[0011] Preferably, the elastic band includes an elastic band body with a second through hole. One end of the elastic band body is fixedly connected to a belt body, and a fixing sleeve is wrapped around the elastic band body. The first bolt is inserted into the second through hole. The elasticity of the elastic band body acts on the back of the hand, keeping the smoke detector in the hand.

[0012] In summary, the technical effects and advantages of this utility model are as follows: 1. Place your hand between the flue gas detector and the elastic band, using the elastic band to press against the back of your hand. This keeps your hand pressed against the flue gas detector, preventing it from falling off. Loosen the nut and pull the cloth belt outward to tighten the elastic band. Conversely, loosen the elastic band and tighten the nut to secure the cloth belt. Adjusting the position of the cloth belt allows you to easily adjust the tightness of the elastic band, preventing slippage and allowing you to adjust the elasticity to match the thickness of the worker's hand.

[0013] 2. Tightening the knob acts on the nut body, causing the nut body to spirally press the pressure plate along the threaded bolt body or loosen the pressure plate, making it convenient to loosen or tighten the cloth belt. Attached Figure Description

[0016] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments.

[0017] like Figure 1 As shown, a high-concentration flue gas detection device includes a flue gas detector 1. The lower end of the flue gas detector 1 is provided with a fixing sleeve 7 and a first bolt 8. An elastic band 6 is fitted inside the fixing sleeve 7. The first bolt 8 passes through the fixing sleeve 7 and is threaded onto the lower part of the flue gas detector 1. One end of the elastic band 6 is fixedly connected to a cloth strip 5. A second bolt 2 is movably inserted inside the cloth strip 5. A nut 4 is threaded onto the second bolt 2. A pressure plate 3 is slidably fitted outside the second bolt 2, and the pressure plate 3 is fitted over the cloth strip 5. By placing a hand between the flue gas detector 1 and the elastic band 6, the elastic band 6 presses against the back of the hand, keeping the hand pressed against the flue gas detector 1 to prevent it from falling off. Loosening the nut 4 allows the cloth strip 5 to be pulled outwards, tightening the elastic band 6. Conversely, loosening the elastic band 6 allows the nut 4 to be tightened, using the nut 4 to press and fix the cloth strip 5 for stable adjustment.

[0018] like Figure 1 and 2 As shown, the second bolt 2 includes a threaded bolt body 21, the upper end of which is fixedly connected to the flue gas detector 1. A limiting groove 22 is formed on the side of the threaded bolt body 21. The limiting groove 22 restricts the rotation of the pressure plate 3, and the threaded bolt body 21 guides the screw of the nut 4.

[0019] like Figure 1 , 2As shown in Figure 3, the pressure plate 3 includes a plate body 31, with a first through hole 33 cut out inside the plate body 31. A threaded bolt 21 is inserted into the first through hole 33, and a stop strip 32 is fixedly connected to the side of the plate body 31. By using the plate body 31 and the stop strip 32 to fit over the fabric belt 5, the stability of the relative position between the pressure plate 3 and the fabric belt 5 is increased.

[0020] like Figure 1 , 2 As shown in Figures 3 and 4, the nut 4 includes a nut body 41, with a knob 42 fixedly connected to the lower part of the nut body 41. The nut body 41 is threadedly mounted on the threaded bolt body 21, and the nut body 41 is in contact with the plate body 31. Turning the knob 42 acts on the nut body 41, causing the nut body 41 to spirally press against the pressure plate 3 or loosen the pressure plate 3 along the threaded bolt body 21.

[0021] like Figure 1 , 2 As shown in Figures 3 and 5, the fabric tape 5 includes a tape body 51. A first fabric ring 53 is fixedly connected to the lower end of the tape body 51, and a second fabric ring 52 is fixedly connected to the other end of the tape body 51. A threaded bolt 21 is movably inserted into the tape body 51, and a plate 31 and a stop strip 32 are fitted onto the tape body 51. Tightening the nut 4 causes the pressure plate 3 to press and fix the tape body 51, and conversely, loosening the nut 4 causes the pressure plate 3 to loosen the tape body 51.

[0022] like Figure 1 , 5 As shown in Figure 6, the elastic band 6 includes an elastic band body 61, on which a second through hole 62 is hollowed out. One end of the elastic band body 61 is fixedly connected to the band body 51. A fixing sleeve 7 is wrapped around the elastic band body 61, and a first bolt 8 is inserted into the second through hole 62. The elastic force of the elastic band body 61 acts on the back of the hand to keep the smoke detector 1 in the hand.

[0023] Working principle: Place your hand between the flue gas detector 1 and the elastic band 6, using the elastic band 6 to press against the back of your hand. This keeps your hand pressed against the flue gas detector 1, preventing it from falling off. Loosen the nut 4 and pull the cloth belt 5 outward to tighten the elastic band 6. Conversely, loosen the elastic band 6 and tighten the nut 4. The nut 4 presses and fixes the cloth belt 5 to stabilize the adjustment result. Turning the knob 42 acts on the nut body 41, causing the nut body 41 to spirally press against the pressure plate 3 or loosen the pressure plate 3 along the threaded bolt body 21.
