Problems solved by technology

[0002] With the continuous enhancement of people's awareness of environmental protection, in order to strengthen the monitoring of water environment quality and grasp the water quality situation in time, a large number of water quality sampling work is required. When sampling deep water bodies, the sampling container is usually lowered to the sampling depth, and then However, the existing sampling cylinder can achieve the purpose of sampling during the sampling process, but after the sampling is completed, the sampling cylinder is often in an open state during the lifting process, resulting in During the lifting process, it is easy to cause the water body inside the sampling cylinder to exchange with water bodies of different depths, which will lead to inaccurate detection results

Embodiment 1

[0031] see Figure 1-3 , the present invention provides a technical solution: a deep water sampling device for water quality detection, comprising a sampling cylinder 1, a top cover 2 is installed on the top of the sampling cylinder 1, and a water inlet 3 is opened on the outer surface of the bottom end of the sampling cylinder 1, The bottom surface of the top cover 2 is fixedly installed with an end block 4, and the inside of the end block 4 is fixedly installed with a remote control motor 5. The remote control motor 5 can facilitate the remote control of the staff. A circular bottom plate is fixedly installed at the bottom end of the rotating rod 6, a sealing ring 10 is provided at the connection between the rotating rod 6 and the end block 4, and an extension rod 7 is symmetrically and fixedly installed on the outer surface of the bottom end of the rotating rod 6, and the extending rod 7 is far away from the rotating rod 6. One end is fixedly installed with a sealing plate ...

Embodiment 2

[0034] see Figure 4-5, the top of the sampling cylinder 1 is provided with a pay-off structure, the pay-off structure includes a wire rod 15, a connecting rope 16 is installed on the top of the sampling cylinder 1, a top block 17 is fixedly installed on the top of the connecting rope 16, and the upper surface of the top block 17 is installed There is an adjustment rope 18, and the outer surface of the wire rod 15 is sleeved with a wire take-up cylinder 19. By setting the wire rod 15, the connecting rope 16, the top block 17, the adjustment rope 18 and the wire take-up cylinder 19, it is convenient for the staff to The descending process of the sampling cylinder 1 is controlled, the two ends of the wire take-up cylinder 19 are fixedly installed with the disks 20, and the two ends of the line rod 15 are symmetrically fixed with the docking disks 21, wherein a group of the disks 20 and the outer surface of the docking disk 21 are fixedly installed. A scale line 22 and a pointer ...

Embodiment 3

[0037] see Figure 7-8 , the outer surface of the sampling cylinder 1 is provided with a connection structure, the connection structure includes a rectangular plate 29, a rectangular plate 29, the upper and lower ends of the rectangular plate 29 are symmetrically fixed with a base 30, and a connection is fixed between the two sets of bases 30. The outer surface of the rod 31 and the connecting rod 31 is sleeved with a turning block 32, and one end of the turning block 32 is fixedly installed with a rubber plate 33. The inside of the rubber plate 33 is provided with a card slot 34, and the leather cover 28 is embedded in the inside of the card slot 34.

Abstract

The invention relates to the technical field of water sampling, in particular to a deep water sampling device for water quality detection, which comprises a sampling barrel, a top cover is mounted at the top end of the sampling barrel, a water inlet is formed in the outer surface of the bottom end of the sampling barrel, an end block is fixedly mounted on the bottom surface of the top cover, and a remote control motor is fixedly mounted in the end block. A rotating rod is installed at the output end of the remote control motor, a sealing ring is arranged at the joint of the rotating rod and the end block, and extension rods are symmetrically and fixedly installed on the outer surface of the bottom end of the rotating rod. By arranging the end block, the remote control motor, the rotating rod, the extension rod, the sealing plate, the sealing gasket, the sealing ring and the like, after the sampling barrel completes sampling at a specified depth, the sealing plate and the sealing gasket can be driven to move under the action of the remote control motor, so that the water inlet is closed; therefore, the situation that the sampling barrel is exchanged with the shallow water body in the lifting process can be effectively avoided, and the detection precision of the later detection process is greatly improved.
