Description

Technical Field

[0001] The utility model relates to the technical field of pollutant collection, in particular to a pollutant collection device for chemical pollution detection. Background Technique

[0002] In environments such as factories and hospitals, some occupational health needs to be detected. The applicant is a detection agency, and factories and hospitals entrust them to conduct detections. Some are on-site detections, and some are on-site samplings. Then the samples are taken back to the company's laboratory for testing. For example, for liquids, on-site sampling is carried out and then taken back to the company's laboratory for processing. During the collection of chemical pollutants, there are solid pollutants, liquid pollutants, and gas pollutants. Among them, liquid pollutants are relatively common. Usually, chemical pollutants have certain corrosiveness. If the skin of the detection personnel directly contacts the pollutants during the sampling process, it may cause certain harm to the human body and even cause irreparable major injuries.

[0003] When collecting pollutants for chemical pollution detection, usually directly hold the sampling bottle to contain the sample by hand, or tie a water bottle with a rope and throw it into the pollution source to fill with water, and then pour it into the sample bottle. The steps are relatively cumbersome. And during the process, in order to avoid contacting the sample, it is necessary to wear protective equipment such as gloves, which is rather inconvenient. Moreover, for the existing pollutant collection devices for chemical pollution detection, during actual use, the portability is poor, and the sample bottle needs to be stored in an additional box, which is rather inconvenient. Therefore, the existing pollutant collection devices for chemical pollution detection have the disadvantages of being inconvenient for quickly collecting samples and inconvenient for carrying the sample bottle.

The output end of the second one-way valve 13 is fixedly connected to a water injection pipe 14. The lower end of the water injection pipe 14 and one end of an overflow exhaust pipe 17 are both arranged inside a sample bottle 15. The middle part of the overflow exhaust pipe 17 is fixedly connected to a third one-way valve 18 on the inner side wall of the collection device housing 1. The lower surface of the collection device housing 1 is threadedly connected to the sample bottle 15. The upper end of the sample bottle 15 is threadedly connected to a bottle cap 16. A plurality of sample bottles 15 and bottle caps 16 are provided and are evenly distributed in a rectangular array on the inner side wall of a storage slot 24. An overflow exhaust pipe 17 is arranged on the inner side wall of the collection device housing 1 below the collection tube 4. A motor 19 is fixedly connected to the inner side wall of the collection device housing 1. One end of the output shaft of the motor 19 is fixedly connected to a turntable 20.

[0029] In order to achieve convenient and rapid sample collection, as shown in the attached Figures 1 to 5As shown in the figure, the present application adopts the following structure. Through the settings of the collection device housing 1, the collection tube 4, the telescopic tube 6, the piston tube 9, and the motor 19, the pollutant collection device for chemical pollution detection has the effect of facilitating the rapid collection of pollutant samples. Through the coordinated settings of the piston tube 9, the first one-way valve 10, the piston plate 11, the second one-way valve 13, the water injection pipe 14, the sample bottle 15, the motor 19, the turntable 20, the connecting block 21, and the eccentric shaft 22, during the use process, according to the distance of the sample, such as by the river or the edge of a low-water pool, loosen the tightening block 5, and the telescopic tube 6 can freely expand and contract on the inner wall of the collection tube 4. After adjusting to the required length, tighten the tightening block 5 to fix the telescopic tube 6. Then, hold the handle 2 and insert the filtering end 7 at the end of the telescopic tube 6 into the liquid to be sampled and collected. Press the button 3. At this time, the motor 19 works, driving the turntable 20 to rotate. Since the eccentric shaft 22 is on the inner wall of the limit groove 23, when the turntable 20 rotates, it can drive the connecting rod 12 to reciprocate in the left and right directions, and then drive the piston plate 11 to reciprocate. When the piston plate 11 moves to the right, the pressure on the left side inside the piston tube 9 decreases, the second one-way valve 13 closes and the first one-way valve 10 opens. At this time, the sample to be detected can be sucked into the inside of the piston tube 9. The settings of the filtering end 7 and the filter screen 8 can filter and block larger impurities such as waterweeds to prevent the collection tube 4 and the telescopic tube 6 from being blocked. When the piston plate 11 moves to the left, the first one-way valve 10 closes and the second one-way valve 13 opens. The pressure on the left side inside the piston tube 9 increases, and then the liquid pollutant sample pumped into the inside of the piston tube 9 is pumped into the inside of the sample bottle 15 on the lower surface of the collection device housing 1 through the water injection pipe 14. As the liquid enters the inside of the sample bottle 15, the pressure inside the sample bottle 15 increases. At this time, the air is discharged from the overflow exhaust pipe 17, and after being filled, the excess liquid can be discharged from the overflow exhaust pipe 17, thus completing the collection operation. After that, unscrew the sample bottle 15 and cover the bottle cap 16 on the upper end of the sample bottle 15. The whole process does not require additional operations and will not cause pollution to the outer surface of the sample bottle 15. After carrying the device to the pollutant side, it can be directly used, thus achieving the purpose of facilitating the rapid collection of samples;
