Description

air pollen collector

technical field

The present invention relates to a pollen collector.

Background technique

Air pollen is the pollen particle that the pollen of the plant can be transported by aerodynamic force after leaving the parent plant and suspended in the air for a certain period of time. Major outdoor allergens. The allergen detection reports of many domestic hospitals pointed out that allergic diseases are related to the sensitization of various pollens. The first prerequisite for the prevention and treatment of hay fever is to use scientific collection devices to collect air pollen, so as to find out the regular characteristics of air pollen type, concentration, and temporal and spatial distribution, and avoid or reduce exposure to air pollen.

At present, air pollen is mainly collected by using the method of glass slides coated with glycerol. However, due to the limitation of the horizontal placement of the slides in this method, generally only pollen with larger specific gravity and faster falling speed can be collected. Pollen collected with long suspension time is less effective. At the same time, this method cannot estimate the impact of different wind directions on pollen dispersal.

Contents of the invention

The object of the present invention is to solve the problem that the traditional air pollen collection device cannot avoid the influence of wind direction, and to provide an air pollen collector.

The air pollen collector consists of a base, a pillar, a fixed stay rope, a turntable, a collection window, a sampling gauze, a T-shaped bracket, a tail fin and a stay rope fixing ring. The base is fixed on the ground, and the pillar is installed on the base On the upper part of the pillar, a stay rope fixed ring is set, one end of the fixed stay rope is connected to the stay rope fix ring, the other end of the fixed stay rope is connected to the ground, and the turntable is installed on the top of the stand, on the turntable A T-shaped support is installed, the tail fin is installed at the end of the vertical side of the T-shaped support, a collection window is respectively installed on the symmetrical two sides of the type support, and a sampling gauze is installed inside the collection window.

Working principle: The turntable of the air pollen collector of the present invention can rotate axially, and the collection window is kept vertical to the wind direction due to the action of the tail fin, so that the sampling gauze net can collect free pollen in the air to the maximum extent.

Advantages of the present invention: the air pollen collector of the present invention is provided with a turntable and a tail fin to ensure that the collection window is always perpendicular to the wind direction, greatly improving the pollen collection effect.

4), open the fixing screw on the upper part of the collection window 5, put into the collection gauze 6, then close the collection window 5 and tighten the fixing screw;

5), open the collection window 5 after a sampling cycle is completed, take off the old sampling gauze 6, and then replace the new sampling gauze 6 for sampling in the next cycle;

6) The tightness of the fixed pull rope 3 and the smoothness of the rotating bearing of the turntable 4 should be checked at least every month for the device, and lubricating oil should be added for lubrication and maintenance if necessary.

Embodiment 2: The difference between this embodiment and Embodiment 1 is that the base 1 is made of cast iron with a diameter of 400 mm and a thickness of 20 mm to form a circular base, and the diameter of the middle of the circular base is 60 mm. Threaded port, used to install pillar 2. Others are the same as the first embodiment.

The middle of the base 1 described in this embodiment is provided with a screw hole, which is bolted to the pillar 2 to securely fix the pillar 2 on the base 1 .

Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the pillar 2 is a cast iron round pipe with a diameter of 60mm, the thickness of the pipe wall is > 3mm, and the lower end of the pillar 2 is set as a screw, and is connected with the The threaded opening provided in the middle of the base (1) coincides with each other, and is used to be connected with the base 1 by bolts. Others are the same as those in Embodiment 1 or 2.

Embodiment 4: The difference between this embodiment and Embodiments 1 to 3 is that the fixed stay rope 3 is a steel wire rope with a diameter of not less than 3mm, which is pulled out obliquely downward by the stay rope fixing ring 9 on the upper part of the pillar 2 and fixed. On the ground, the rope length is 1200mm. Others are the same as the specific embodiments 1 to 3.

Embodiment 5: The difference between this embodiment and Embodiments 1 to 4 is that the turntable 4 is composed of an upper plate and a lower plate that can freely rotate and move, and the lower plate of the turntable 4 is fixedly connected with the pillar 2 by bolts.

The freely rotatable upper plate of the turntable 4 described in this embodiment can rotate freely in the axial direction, so it is ensured that the bolts on the freely rotatable upper plate are fixedly connected with the T-shaped bracket 7 together with it and can freely rotate in the axial direction. turn.

Specific embodiment six: the difference between this embodiment and one of specific embodiments one to five is: the height of the collection window 5 is 250mm, the width is 270mm, and the thickness is 40mm, and a width of 10mm and a depth of 10mm are all set around the collection window 5. 10mm groove, sampling gauze 6 collection window 5 inner width 10mm deep 10mm groove, and the upper frame of collection window 5 can be opened freely. Others are the same as the specific embodiments 1 to 5.

In this embodiment, the upper frame of the collection window 5 can be opened freely to facilitate the disassembly and replacement of the sampling gauze 6 .

Embodiment 7: The difference between this embodiment and Embodiments 1 to 6 is that the sampling gauze 6 is prepared according to the following method. First, the medical cotton gauze is soaked in a 50% silicone oil solution treatment to obtain medical cotton gauze soaked with a mass fraction of 50% silicone oil solution, the medical cotton gauze soaked with a mass fraction of 50% silicone oil solution is superimposed to four layers, and then surrounded by an iron frame with a width of 270mm and a height of 250mm Fixed, promptly obtains the sampling gauze 6. Others are the same as the specific embodiments 1 to 6.

In this embodiment, medical cotton gauze soaked with a mass fraction of 50% silicone oil solution is used as the gauze of the sampling gauze 6. The silicone oil is easily soluble in water, not volatile and has a certain viscosity. Diluting the silicone oil to 50% aqueous solution first and then soaking the cotton medical gauze is conducive to the rapid and uniform absorption of the gauze, and facilitates the production of the sampling gauze (too thick silicone oil will cause inconvenience in various operations). In addition, after repeated outdoor experiments, using four layers of medical cotton gauze soaked in 50% silicone oil solution can capture the maximum amount of pollen while ensuring the smooth passage of air through the sampling net. If the number of gauzes is less than four layers, part of the pollen will pass through the sampling gauze with the airflow and cannot be captured, while more than four layers of gauze will seriously hinder the passage of air, and the pollen collection effect will also become poor. Aids in the collection of free pollen in the air.
