Problems solved by technology

[0003] When sampling and testing water bodies, it is necessary to collect water at different depths in rivers and lakes for comprehensive testing. Compared with water sampling in deeper rivers and lakes, a rope is usually used to tie the sampling cylinder, and then put the rope to the place where sampling is required. However, due to the opening of the sampling cylinder, when the sampling is completed, when the sampling cylinder is raised by the pull rope, due to the different water pressure at different depths, the samples in the sampling cylinder will be separated from the water at different depths. The exchange of streams will cause the final sample to fail to meet the sampling standard, thus affecting the final test result

Embodiment 1

[0033] The embodiment of the invention discloses a sampling device for water body detection, such as Figure 1-10As shown, including the base 1, the upper surface of the base 1 is fixedly connected with the fixed column 2, the upper surface of the fixed column 2 is fixedly connected with the connecting plate 3, and the lower surface of the connecting plate 3 is fixedly connected with multiple sets of connecting plates, two sets of connecting plates As a group, the corresponding side walls of the two groups of connecting plates are rotatably connected with a rotating column, and the center of the rotating column is fixedly sleeved with a guide wheel 37, and the first steel wire rope 7 and the second steel rope 18 pass through the corresponding guide wheel 37 and The center of the upper surface of the first connecting bolt 6 and the second connecting bolt 17 is fixedly connected, the bottom of the connecting plate 3 is connected with the sampling cylinder 4 through the transmissi...

Embodiment 2

[0037] The embodiment of the invention discloses a method for using a sampling device for water body detection, such as Figure 1-10 As shown, when the present invention is in use, by fixing the base 1 on the ship, the ship sails to the position where the rivers and lakes need to be sampled, by connecting the first connecting bolt 6 and the second connecting bolt 6 on the first wire rope 7 and the second wire rope 18 The connecting bolt 17 is threadedly connected to the threaded groove on the ring block 5 and the clamping plate 15. By picking up the counterweight 38, the through groove on the counterweight 38 is aligned with the threaded groove at the bottom of the sampling cylinder 4, and the counterweight is connected by the bolt. Block 38 is fixed at the bottom of sampling cylinder 4 .

[0038] Further, by turning the first handle 21 forward, the first handle 21 drives the driving wheel 22 to rotate, the driving wheel 22 drives the driven wheel 26 to rotate through the tran...

Abstract

The invention discloses a sampling device for water body detection and a using method thereof, and relates to the field of sampling devices. According to the sampling device for water body detection and the using method thereof, the device comprises a base, wherein a fixed column is fixedly connected to the upper surface of the base, a connecting plate is fixedly connected to the upper surface ofthe fixed column, and a sampling barrel is connected to the lower part of the connecting plate through a transmission mechanism. According to the sampling device for water body detection and the usingmethod thereof, the sampling barrel is submerged to a certain depth of rivers and lakes through the transmission mechanism, a second steel wire rope is pulled to enable a rod to pull a clamping spring to move upwards, a fixing plug is separated from the opening of the sampling barrel, a sample enters the sampling barrel, the fixing plug is plugged in the opening of the sampling barrel by pullingthe first steel wire rope, loosening the second steel wire rope and resetting the clamping spring, the situation that the sample in the sampling barrel exchanges and flows with water in different depths is prevented, and finally accurate detection of the sample is facilitated.

Description

technical field [0001] The invention relates to the technical field of sampling devices, in particular to a sampling device for water body detection and a use method thereof. Background technique [0002] Water is the source of life. Human beings cannot do without water in life and production activities. The quality of drinking water is closely related to human health. With the development of social economy, scientific progress and the improvement of people's living standards, people's drinking Water quality requirements continue to increase, and drinking water quality standards are also continuously developed and improved accordingly. Due to the formulation of drinking water quality standards and people's living habits, culture, economic conditions, scientific and technological development levels, water resources and their water quality status, etc. It is related to many factors, not only between countries, but also between different regions of the same country, there are d...
