Description

Technical Field

[0001] The utility model relates to a sampling detection device, in particular to an environmentally friendly sewage sampling detection device, belonging to the technical field of sewage sampling. Background Art

[0002] Environmental protection, full name environmental protection, refers to the general term for various actions taken by human beings to solve real or potential environmental problems, coordinate the relationship between human beings and the environment, and ensure the sustainable development of economy and society. The protection of water resources is very important in environmental protection, so it is necessary to treat sewage. Sewage refers to the discharged water from life and production and is polluted to a certain extent. Sewage has lost its original use function due to the addition of new substances or changes in external conditions. From the perspective of the source of sewage, it can be divided into liquid or water with waste mixed with groundwater, surface water, blizzard, etc. discharged from residences, institutions, commerce or industry. In the process of sewage treatment, it is necessary to sample and test the sewage, and decide the way to treat the sewage according to the results of the sampling test;

[0028] In one embodiment, two through holes 10 are provided on the lower surface of the waterproof box 4, and a sealing ring 708 is bonded and fixed to the inner wall of the through hole 10. The inner wall of the sealing ring 708 is in active contact with the outer side of the output shaft of the electric push rod 701. The output shaft of the electric push rod 701 extends to the bottom of the waterproof box 4 through the through hole 10, and the sealing ring 708 effectively prevents water from entering the interior of the waterproof box 4 through the through hole 10.

[0029] In one embodiment, the electrical output end of the battery pack 702 is electrically connected to the input end of the controller 703, the wireless remote control receiving module 704 and the electric push rod 701 through a wire, the electrical output end of the wireless remote control receiving module 704 is electrically connected to the input end of the controller 703 through a wire, the electrical output end of the controller 703 is electrically connected to the input end of the electric push rod 701 through a wire, the electrical input end of the wireless remote control receiving module 704 is electrically connected to the output end of an external wireless remote control transmitting module, the controller 703, the wireless remote control receiving module 704 and the electric push rod 701 are powered by the battery pack 702, the signal is transmitted to the controller 703 through the wireless remote control receiving module 704, and the opening and closing of the electric push rod 701 are controlled by the controller 703.

[0030] In one embodiment, a water outlet 11 is opened on one side of the sampling tube 5 , and a rubber plug is movably provided inside the water outlet 11 , so that the collected sample is guided out from the interior of the sampling tube 5 through the water outlet 11 .

[0031] The utility model is in operation: when it is necessary to sample sewage, the wire reel 3 is started to release the wire, and the waterproof box 4 and the sampling tube 5 are driven downward by the action of the counterweight block 12. After the waterproof box 4 and the sampling tube 5 are lowered to a suitable height by observing the scale lines on the pull rope, the wire reel 3 is closed. At this time, the signal is transmitted to the wireless remote control receiving module 704 through the external wireless remote control transmitting module, and the wireless remote control receiving module 704 transmits the received signal to the controller 703. Under the action of the controller 703, the electric push rod 701 is started, and the electric push rod 701 drives the connecting plate 706 to move upward, and the connecting plate 706 drives the ring 705 and the rubber ring 707 to move upward, so that the ring 705 and the rubber ring 707 are separated from the connecting plate 706. At this time, the electric push rod 701 is closed, so that the sewage enters the interior of the sampling tube 5 through the water inlet hole 6. After the water is taken, the signal is transmitted to the wireless remote control receiving module 704 again through the external wireless remote control transmitting module, and the wireless remote control receiving module 704 transmits the received signal to the controller 703.

[0032] After the sampling is completed, the wire reel 3 is started to reel in the wire, the waterproof box 4 and the sampling tube 5 are removed from the sewage, the rubber plug is pulled out, and the water sample collected in the sampling tube 5 is transferred to the detection box through the water outlet 11. The sampling tube 5 is then rotated, and the sampling tube 5 drives the external thread block 8 to rotate, so that the external thread block 8 is separated from the internal thread ring 9. At this time, the sampling tube 5 can be removed from the lower surface of the waterproof box 4 for cleaning, making it easy to remove the sampling tube 5 for cleaning.

[0033] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
