Description

Technical Field

[0001] The utility model relates to the technical field of smoke measurement, in particular to a smoke measuring telescope. Background Art

[0002] Smoke blackness is an indicator of the relative concentration of smoke dust in smoke detected by human vision. Although this indicator cannot directly and accurately reflect the content of harmful substances in smoke, its determination method is simple, low-cost and rapid, and it is still widely used in actual detection. The commonly used smoke blackness detection method is the Ringelmann blackness diagram method, in which a qualified observer observes the color of smoke at the chimney outlet through a smoke measuring telescope and compares it with the Ringelmann blackness diagram to determine the level of smoke blackness.

[0003] Existing smoke detection telescopes, for example, Chinese patent application number CN201520245693.0, discloses a smoke detection telescope, which includes a shell, an eyepiece and an objective lens are respectively arranged on both sides of the shell, a light screen is arranged in the shell, a Ringelmann blackness strip is arranged on the light screen, a handle is arranged at the bottom end of the shell, a fixed seat is arranged at the top of the shell, a support rod is arranged on the fixed seat, a rotating shaft is arranged at the top of the support rod, and a wind vane is arranged on the rotating shaft. It has a simple structure and reasonable design, and can automatically determine the wind direction and time itself, which reduces the labor intensity of the detector and improves the detection efficiency and the accuracy of the detection result. Its shortcomings are that although a wind vane for monitoring the direction is set, there is a lack of a wind speed monitoring device for judging whether the wind speed meteorological conditions are suitable for observation, and there is a lack of an upward viewing angle of the telescope body for measurement. Both of these items require the detector to make a judgment by himself. Since the subjectivity of the detector's self-judgment is strong, this will reduce the accuracy of the detection result and reduce the detection efficiency.

[0004] Therefore, the utility model provides a smoke detection telescope. Utility Model Content

[0025] Among them, by setting the rotating frame 21, the rotating arm 23, the support seat 19 and the knob 20, the front and rear angle (i.e., the upward viewing angle of the telescope body 5) can be adjusted by the knob 20 according to the actual observation needs, and the telescope body 5 can be clamped and fixed by setting the arc-shaped baffle structure 18, and the setting of the first rubber layer 24 is convenient to improve the friction between the arc-shaped baffle structure 18 and the telescope body 5, thereby improving the stability of the overall structure.

[0026] In this embodiment, the angle disk 22 is a semicircular protractor body, a scale ring 9 is provided on the angle disk 22 , a connector 17 is rotatably connected to the center of the angle disk 22 , and the connector 17 is connected to an arc-shaped baffle structure 18 .

[0027] Among them, by setting the connecting body 17, the arc-shaped baffle structure 18 can be rotatably connected between the connecting body 17 and the angle disk 22, so as to facilitate the detection of the upward viewing angle of the telescope body 5. In addition, the position where the connecting body 17 and the arc-shaped baffle structure 18 are connected is set on the center line position of the telescope body 5.

[0028] In this embodiment, an arc groove 10 is provided on the angle disk 22, the scale ring 9 and the arc groove 10 are distributed in a concentric circle outwardly expanding structure, a pointer 12 for reading the angle is provided on the plug-in frame 11, the arc groove 10 is slidably connected to the plug-in frame 11, a groove 15 is provided on the plug-in frame 11, and a second rubber layer 14 is provided on the inner wall of the groove 15; the telescope body 5 is provided with a plug-in boss 16 matching the groove 15.

[0030] In this embodiment, a lens cover 8 is detachably connected to the end of the objective lens 7 .

[0031] In this embodiment, a timing reminder 13 is also provided on the base 3 .

[0032] In this embodiment, the wind speed and direction detection structure is a wind speed and direction sensor 4. At the same time, the wind speed and direction sensor 4 is a digital wind speed and direction sensor 4, which is easy to read.

[0033] Furthermore, the base 3 is arranged on the pan-tilt seat 2 .

[0034] Working principle: First, use the wind speed and direction sensor 4 to monitor and determine whether the current wind speed and meteorological conditions are suitable for observation. If the wind speed is greater than 4.5m / s (see the National Ecological Environment Standard HJ1287-2023 of the People's Republic of China for details), it is not suitable for observation. If the wind speed is less than 4.5m / s, install the tripod 1, clamp the telescope body 5 between the two relatively arranged arc-shaped baffle structures 18, and then insert the plug-in protrusion 16 into the groove 15, observe the Ringelmann diagram through the eyepiece 6, and adjust the eyepiece 6 (the eyepiece 6 can be adjusted for clarity through the matching eyepiece screw sleeve, this structure is a prior art and is no longer limited here) until the Ringelmann grid lines are clear. At the same time, observe the thin rod on the top of the chimney, such as a lightning rod, through the eyepiece 6, and adjust the objective lens 7 (the objective lens 7 can be adjusted through the matching eyepiece screw sleeve. The clarity is adjusted by the objective lens screw sleeve, which is a prior art and is not limited here) until the target is clear. During this process, the upward viewing angle of the telescope body 5 can be adjusted by the knob 20. It should be noted that the upward viewing angle for observing flue gas should not be too large, and should not be greater than 45°. This angle can be obtained by directly reading the position of the pointer 12 on the scale ring 9 to obtain the current upward viewing angle of the telescope body 5. The observer should compare the Ringelmann concentration diagram in the Ringelmann smoke measuring telescope with the smoke color at the chimney outlet, and record the blackness. For pollution sources with very stable flue gas emissions, observations can be made twice per minute, and readings can be recorded every 30 seconds for continuous observation for 30 minutes; for pollution sources with unstable flue gas emissions, observations can be made four times per minute, and readings can be recorded every 15 seconds for continuous observation for 30 minutes.
