Description

Technical Field

[0001] The utility model relates to the technical field of sampling bottles, in particular to a sampling bottle capable of adjusting the sampling depth. Background Art

[0002] A sampling bottle is a container used to collect water samples when sampling water quality. By using a sampling bottle, water samples can be collected from different water sources for subsequent water quality analysis and monitoring. The sampling bottle can effectively maintain the integrity of the water sample, avoid contact between the sample and the external environment, reduce contamination and distortion, and prevent changes in the chemical composition of the sample, thereby ensuring the accuracy of the water quality analysis results.

[0003] When the sampling bottle is used, the sampling bottle is connected to a rope and dropped into a water area where water quality needs to be collected. At this time, the water in the water area flows into the interior of the sampling bottle through the sampling port. When the sampling bottle adjusts the sampling depth and needs to collect water from deep water areas, in the process of the sampling bottle sinking to the deep water area, water from shallow water areas is easy to enter through the sampling port of the sampling bottle, which can easily cause water from different water depths to mix together, affecting the accuracy of the water collected by the sampling bottle. Therefore, we propose a sampling bottle with adjustable sampling depth. Utility Model Content

[0004] The utility model aims to provide a sampling bottle with adjustable sampling depth, so as to solve the problem raised in the above background technology that when the sampling bottle adjusts the sampling depth and needs to collect water from deep water bodies, water bodies at different water depths are mixed together, so that the accuracy of water collection by the sampling bottle is affected.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sampling bottle for adjusting the sampling depth, comprising a winding frame, a measuring rope and a sliding rod, the winding frame is connected to the sampling tube through the measuring rope, a support plate is fixed to the inner side of the sampling tube, and the support plate is fixed to the underwater motor, the output shaft of the underwater motor is fixed to the first bevel gear, the first bevel gear is connected to one end of the bevel gear rod, and the other end of the bevel gear rod is connected to the second bevel gear, the first bevel gear, the bevel gear rod and the second bevel gear are respectively movably connected to the support plate through bearings, one end of the sliding rod extends through the interior of the second bevel gear, and the sliding rod is slidably connected to the support plate.

[0014] Preferably, a sealing gasket is bonded to the outer side of the fixing block, and the sealing gasket is made of rubber material.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows: the sampling bottle with adjustable sampling depth starts the underwater motor, so that the water in the deep water area enters the sampling tube through the water inlet, and the gas inside the sampling tube is discharged through the exhaust groove. After the sampling is completed, the underwater motor is started again to move the slide bar downward, close the exhaust groove and the water inlet, so that the sampling bottle can adjust the sampling depth. When collecting water in the deep water area, it is not easy to mix water at different water depths. The docking cover is rotated to take out the fixed block from the inside of the water outlet. At this time, the staff can quickly take out the water inside the sampling tube.

[0016] 1.

After the sampling is completed, the underwater motor is started again to move the slide bar downward, close the exhaust groove and the water inlet, so that the water collected in the sampling tube will not flow out, so that the sampling bottle can adjust the sampling depth. When collecting water in the deep water area, it is not easy to mix water at different water depths, so that the accuracy of the water collected by the sampling bottle is not easily affected;

[0017] 2.

When the docking cover is completely separated from the water outlet, the fixed block is taken out from the inside of the water outlet, and the staff can quickly take out the water inside the sampling tube.

The first bevel gear 4 and the second bevel gear 6 are respectively meshed and connected to the bevel gear rod 5, and the second bevel gear 6 is threadedly connected to the slide rod 7. The cross-sectional size of the lower end of the slide rod 7 matches the cross-sectional size of the slide groove 15. The connecting pad 11 and the fixing pad 16 are made of rubber material, the exhaust groove 10 is squeezed against the connecting pad 11, and the water inlet 12 is squeezed against the fixing pad 16.

[0026] In specific implementation, according to Figure 1-Figure 4 When the sampling tube 102 is used, the sampling tube 102 is connected to the measuring rope 101, and then the sampling tube 102 is put into the water area where water quality needs to be collected, and the lowering speed of the measuring rope 101 is controlled.
