Description
Technical Field
[0001] The utility model relates to the technical field of dust monitoring, in particular to a wind-proof dust sampling structure. Background Art
[0002] Dust sampling is a method used to collect suspended particulate matter in the air. Airborne particles are drawn in and collected on filters or other media, usually using specially designed equipment such as a dust monitor or sampler. These samples can be analyzed for composition, concentration and size distribution of the particles to assess air quality and environmental pollution. Dust sampling is often used in environments such as industrial emissions, construction sites, road construction, etc. to monitor and assess particulate pollution in the air.
[0003] The existing wind-proof dust sampling head structure usually does not have wind-proof measures. When the wind speed is high, the collected dust data will be too different and cannot adapt to special environments. Utility Model Content
[0004] In view of the above problems, the purpose of the utility model is to provide a wind-proof dust sampling structure to solve the problem that the existing wind-proof dust sampling head structure usually does not have wind-proof measures, which will cause the collected dust data to differ too much when the wind speed is high and cannot adapt to special environments.
[0005] To achieve the above objectives, the utility model adopts the following technical solution: a wind-proof and dust-proof sampling structure, comprising a sampling head body and a lifting rod, the top of the sampling head body is threadedly installed with a first rain shield, and the middle part of the sampling head body is installed with a second rain shield, the top of the sampling head body is plugged with a lifting rod, and the bottom of the lifting rod is connected with a limiting pressure rod, the bottom of the limiting pressure rod is connected with an annular pad, and the bottom of the annular pad is bonded with a first damping rubber pad, the outer side of the sampling head body is plugged with a speed reduction plate, and the inner wall of the speed reduction plate is evenly spaced with hemispherical bumps, a limiting slide rail is installed at the connection between the speed reduction plate and the sampling head body, and a second damping rubber pad is installed at the bottom of the speed reduction plate.
[0006] The beneficial effects of the utility model are as follows: when the wind speed is too high, the air reaches the speed reduction plate, and the hemispherical protrusions installed at equal intervals on the inner side of the speed reduction plate reduce the wind speed, and after the wind contacts the speed reduction plate, the speed reduction plate is pushed to rotate along the limiting slide rail. The rotation of the speed reduction plate can further reduce the wind speed. This method can effectively reduce the wind speed and ensure the collection of dust data.
[0007] To facilitate the rotation of the first rain shield:
[0008] As a further improvement of the above technical solution: a hexagonal prism protrusion is arranged on the top of the first rain shield.
[0009] The beneficial effect of this improvement is that the hexagonal prism protrusion can facilitate the user to drive the first rain shield to rotate. The rotation of the first rain shield can squeeze the first damping rubber pad through the lifting rod, the limiting pressure rod and the annular pad, thereby increasing the pressure between the first damping rubber pad and the speed reduction plate, and increasing the friction between the speed reduction plate and the first damping rubber pad.
[0010] To facilitate the first rain shield squeeze lift rod:
[0011] As a further improvement of the above technical solution: a sliding groove is provided at a position of the first rain shield close to the lifting rod.
[0012] The beneficial effect of this improvement is that the sliding groove can reduce the friction between the first rain shield and the lifting rod when the first rain shield rotates, thereby facilitating the fixing of the position of the lifting rod.
[0013] In order to increase the friction when the deceleration plate rotates:
[0014] As a further improvement of the above technical solution: the first damping rubber pad is tightly fitted to the speed reduction plate.
[0015] The beneficial effect of this improvement is that the tightly fitting first damping rubber pad and the speed reduction plate can effectively increase the friction between the speed reduction plate and the first damping rubber pad, slow down the rotation speed of the speed reduction plate, and absorb the impact of wind, thereby ensuring the efficiency and effect of reducing wind speed.
[0016] In order to facilitate the limit pressure rod to push the annular pad to squeeze the first damping rubber pad:
[0017] As a further improvement of the above technical solution: the limit pressure rod and the sampling head body are plug-in connected.
[0018] The beneficial effect of this improvement is that the plug-in connection can limit the lifting and lowering of the limiting pressure rod to ensure the uniformity of extrusion.
[0019] To ensure the efficiency of air intake:
[0020] As a further improvement of the above technical solution: the cross section of the speed reduction plate is arranged in an I-shape.
[0021] The beneficial effect of this improvement is that the I-shaped setting can facilitate the wind to contact the speed reduction plate from multiple angles.
[0022] To facilitate dust entry:
[0023] As a further improvement of the above technical solution: the inner side of the bottom surface of the hemispherical projection is inclined.
[0024] The beneficial effect of this improvement is that the inclined setting of the bottom of the speed reduction plate allows the dust in the air to enter the interior of the sampling head body with the wind to sample the dust, thereby ensuring the accuracy and effect of the sampling.
[0025] In order to increase the friction when the deceleration plate rotates:
[0026] As a further improvement of the above technical solution: the second damping rubber pad and the sampling head body are arranged with their axes coincident, and the second damping rubber pad and the sampling head body are connected by snap-fitting.
[0027] The beneficial effect of this improvement is that the second damping rubber pad arranged with the axis coinciding can ensure the friction between the speed reduction plate and the second damping rubber pad, thereby ensuring the rotation speed of the speed reduction plate.

[0035] like Figure 1-5As shown, the wind-proof dust sampling structure includes a sampling head body 1 and a lifting rod 2, the top of the sampling head body 1 is threadedly installed with a first rain shield 11, and the middle part of the sampling head body 1 is installed with a second rain shield 12, the top of the sampling head body 1 is plugged with a lifting rod 2, and the bottom of the lifting rod 2 is connected with a limiting pressure rod 21, the bottom of the limiting pressure rod 21 is connected with an annular pad 22, and the bottom of the annular pad 22 is bonded with a first damping rubber pad 23, the outer side of the sampling head body 1 is plugged with a speed reduction plate 3, and the inner wall of the speed reduction plate 3 is evenly spaced with hemispherical bumps 31, the connection between the speed reduction plate 3 and the sampling head body 1 is installed with a limiting slide rail 32, and the bottom of the speed reduction plate 3 is installed There is a second damping rubber pad 4. When the wind speed is too high, the air reaches the speed reduction plate 3. The hemispherical protrusions 31 installed at equal intervals on the inner side of the speed reduction plate 3 reduce the wind speed. After the wind contacts the speed reduction plate 3, the speed reduction plate 3 is pushed to rotate along the limiting slide rail 32. The rotation of the speed reduction plate 3 can further reduce the wind speed. This method can effectively reduce the wind speed and ensure the collection of dust data. The top of the first rain shield 11 is provided with a hexagonal prism protrusion. The hexagonal prism protrusion can facilitate the user to drive the first rain shield 11 to rotate. The rotation of the first rain shield 11 can squeeze the first damping rubber pad 23 through the lifting rod 2, the limiting pressure rod 21 and the annular pad 22, thereby increasing the pressure between the first damping rubber pad 23 and the speed reduction plate 3 and increasing the speed reduction. The friction between the plate 3 and the first damping rubber pad 23, the first rain shield 11 is provided with a slide groove near the lifting rod 2, and the slide groove can reduce the friction between the first rain shield 11 and the lifting rod 2 when the first rain shield 11 rotates, so as to facilitate the fixation of the position of the lifting rod 2, the first damping rubber pad 23 and the speed reduction plate 3 are tightly fitted, and the tightly fitted first damping rubber pad 23 and the speed reduction plate 3 can effectively increase the friction between the speed reduction plate 3 and the first damping rubber pad 23, slow down the speed of rotation of the speed reduction plate 3, and then absorb the impact of wind, so as to ensure the efficiency and effect of reducing wind speed, the limit pressure rod 21 and the sampling head body 1 are plug-in connected, and the plug-in connection can be used for the limit pressure rod The lifting and lowering of 21 is limited to ensure the uniformity of extrusion. The cross-section of the speed reduction plate 3 is set in an I-shaped manner. The I-shaped setting can facilitate the wind to contact the speed reduction plate 3 from multiple angles. The inner side of the bottom surface of the hemispherical protrusion 31 is inclined. Through the inclined setting of the bottom of the speed reduction plate 3, the dust in the air can enter the interior of the sampling head body 1 with the wind to sample the dust, thereby ensuring the accuracy and effect of sampling. The second damping rubber pad 4 and the sampling head body 1 are arranged with the axis coincident, and the second damping rubber pad 4 and the sampling head body 1 are connected by a snap-fit connection. The second damping rubber pad 4 with the axis coincident setting can ensure the friction between the speed reduction plate 3 and the second damping rubber pad 4, thereby ensuring the rotation speed of the speed reduction plate 3.
[0036] The working principle of the utility model is as follows: when using the device, the sampling head is installed on the sampling device to connect the two, and the convex block above the first rain shield 11 is rotated to push the lifting plug rod 2, the limiting pressure rod 21 and the annular pad 22 to squeeze the first damping rubber pad 23, thereby increasing the pressure between the first damping rubber pad 23 and the speed reduction plate 3. When the wind speed is too high, the air reaches the speed reduction plate 3, and the hemispherical convex blocks 31 installed at equal intervals on the inner side of the speed reduction plate 3 reduce the wind speed, and after the wind contacts the speed reduction plate 3, the speed reduction plate 3 is pushed to rotate along the limiting slide rail 32. The rotation of the speed reduction plate 3 can further reduce the wind speed, and the wind enters the interior of the sampling head body 1. This method can effectively reduce the wind speed and ensure the collection of dust data. After the wind contacts the speed reduction plate 3, the dust in the air can enter the interior of the sampling head body 1 with the wind through the inclined setting of the bottom of the speed reduction plate 3 to sample the dust, thereby ensuring the accuracy and effect of the sampling.
