Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring technology, specifically to an environmental monitoring air collection device. Background Technology

[0002] Environmental monitoring refers to the monitoring and analysis of various substances and factors in the environment to assess environmental quality and determine whether the environment is polluted. Environmental monitoring typically includes the testing of air, water, soil, noise, etc. Air monitoring can measure the concentration of pollutants in the air, such as particulate matter, sulfur dioxide, nitrogen oxides, ozone, etc., to assess the impact of air quality on human health and the ecological environment.

[0003] A search revealed that Chinese Patent Publication No. CN215931426U discloses a remote air collection device for environmental monitoring, comprising a base, a support column, a control box, and an antenna. The support column is fixed to the upper center of the base, the control box is mounted on one side wall of the support column, the antenna is mounted on the control box, a support plate is mounted on the upper end of the support column, a gas collection bottle is fixed to the upper end of the support plate, and an exhaust pipe is connected to one side wall of the gas collection device. The beneficial effects are: by incorporating a vacuum pump and a pressure gauge, when the device is idle, the vacuum pump extracts air from the gas collection bottle, creating a vacuum inside the bottle. The pressure gauge monitors the pressure inside the bottle in real time. This avoids the growth of microorganisms in the residual air inside the bottle, which could affect subsequent air collection data. Furthermore, because the bottle is in a vacuum state, air can automatically enter the collection bottle the next time air is extracted, improving the device's practicality.

[0004] However, this device also has the following drawbacks:

[0005] This device uses a collection bottle to collect gas samples. After long-term use, pollutants will remain in the collection bottle, which will contaminate the gas samples and directly affect the final environmental testing results. This device does not solve this problem. Utility Model Content

[0006] The purpose of this invention is to provide an environmental monitoring air collection device. By using a push rod and a locking connector, a piston can be moved to collect gas into a sampling tube. By setting a fixing component, a new sampling tube can be replaced after each sampling, thereby avoiding contamination of the gas sample and ensuring the accuracy of the test results, thus solving the problems mentioned in the background art.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4 This utility model provides a technical solution:

[0026] An environmental monitoring air collection device includes a sampling tube 1, a collection port 2 fixedly installed at one end of the sampling tube 1, a sealing plug 12 sealingly snapped into the collection port 2, a piston plate 13 slidably installed inside the sampling tube 1, and an opening provided at the other end of the sampling tube 1, with a snap-fit ​​connector 14 fixedly installed on one side of the piston plate 13.

[0027] By setting up sampling tube 1, a new sampling tube 1 can be replaced after each sampling, thereby avoiding contamination of the gas sample and ensuring the accuracy of the test results. By setting up piston plate 13, a negative pressure can be formed in sampling tube 1 by pulling piston plate 13, thereby drawing the air sample from collection port 2 into sampling tube 1. By setting up sealing plug 12, sampling tube 1 can be sealed to further prevent air sample contamination.

[0028] It also includes a fixing component, which includes a placement groove 3, in which the sampling tube 1 is placed. A semi-circular plate 4 is fixedly installed at one end of the placement groove 3, and a fixing plate 5 is fixedly installed at the other end of the placement groove 3. A through hole is opened in the center of the fixing plate 5, and the push rod 8 and the snap-fit ​​seat 9 are in sliding clearance fit with the through hole.

[0029] By using the semi-circular plate 4 and the fixed plate 5 in conjunction with the placement groove 3, the sampling tube 1 can be limited to prevent the sampling tube 1 from shifting during sampling, thus ensuring smooth sampling.

[0030] It also includes a pulling assembly, which includes a mounting base 7 and a push rod 8. The mounting base 7 is fixedly connected to the fixing plate 5 through four sets of connecting rods 6. The push rod 8 is slidably engaged with the mounting base 7. A snap-fit ​​seat 9 is fixedly installed at one end of the push rod 8. A second spring 10 is slidably sleeved on the surface of the push rod 8. One end of the second spring 10 abuts against the mounting base 7. The other end of the second spring 10 is fixedly connected to a limiting plate 11. The limiting plate 11 is fixedly installed at the other end of the push rod 8.

[0031] By setting the push rod 8, the push rod 8 can push the locking seat 9 and the locking connector 14 to engage by pushing the limiting plate 11. At the same time, the second spring 10 is compressed. After the limiting plate 11 loses its pushing force, the second spring 10 pushes the limiting plate 11 and the push rod 8 to pull the locking seat 9 and the locking connector 14 to move, thereby driving the piston plate 13 to move, so as to collect gas samples into the sampling tube 1, which is convenient for operators to take samples and thus improves work efficiency.

[0032] The snap-fit ​​seat 9 and the snap-fit ​​connector 14 snap-fit ​​together. A break groove 15 is provided on one side surface of the snap-fit ​​connector 14. The snap-fit ​​connector 14 includes two sets of symmetrically arranged snap-fit ​​blocks 901. The snap-fit ​​blocks 901 snap-fit ​​with the snap-fit ​​connector 14. A limit ring is fixedly installed at the bottom of the snap-fit ​​block 901. The snap-fit ​​block 901 and the limit ring are slidably installed in the mounting cavity 902. The mounting cavity 902 is opened at the top and bottom of one side of the tube body 905. Two sets of first springs 903 are provided in the mounting cavity 902. One end of the first spring 903 is fixedly connected to the mounting cavity 902. The other end of the first spring 903 abuts against the snap-fit ​​block 901. One side of the tube body 905 is fixedly connected to one end of the push rod 8. A notch 904 is provided at the top of the tube body 905.

[0033] By setting the snap-fit ​​block 901, when the snap-fit ​​seat 9 contacts the snap-fit ​​connector 14, the snap-fit ​​connector 14 will push the snap-fit ​​block 901 to move into the mounting cavity 902, and at the same time compress the first spring 903. After passing the snap-fit ​​connector 14, the snap-fit ​​block 901 will automatically pop out under the action of the elastic force of the first spring 903 and snap-fit ​​with the snap-fit ​​connector 14, reducing the operation steps and improving work efficiency. After sampling, the end of the sampling tube 1 with the collection port 2 can be lifted upwards, and the snap-fit ​​connector 14 can be broken through the break groove 15, thereby removing the sampling tube 1, further reducing the operation steps and improving work efficiency. By setting the notch 904, it is easy for the operator to remove the snap-fit ​​connector 14, thus facilitating the next sampling.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
