[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0028] like Figures 1-6 As shown, the utility model provides a water source sampling and storage device for water environment detection, including: a sampling barrel 1, a storage bin 2 is provided in the sampling barrel 1, a filter screen 3 is installed on the top barrel wall of the sampling barrel 1, and a cover plate 12 is installed on the top of the sampling barrel 1; a sealing plate 7, the sealing plate 7 is slidably connected to the inner wall of the sampling barrel 1; a stirring member, the stirring member is located inside the sampling barrel 1, the stirring member passes through the sealing plate 7, and is located below the sealing plate 7; a temperature control component, the temperature control component is installed in the sampling barrel 1, and is used to adjust the temperature in the storage bin 2.

[0029] A water inlet is provided on the top wall of the sampling barrel 1. In this embodiment, there are two water inlets, which are symmetrically arranged. A filter 3 is installed at the water inlet to filter impurities in the water sample.

[0030] like Figure 6 As shown, the blocking plate 7 includes a plate body 701 and a baffle wall 702. The plate body 701 and the baffle wall 702 are an integrally formed structure. The baffle 14 is vertically fixed below both sides of the plate body 701. The baffle wall 702 is an arc-shaped structure, which fits the inner wall of the sampling barrel 1. The cross-sectional area of the plate body 701 is smaller than the internal cross-sectional area of the sampling barrel 1, which facilitates the water sample to enter the storage bin 2; the density of the plate body 701 and the baffle wall 702 is smaller than the density of water, which facilitates the blocking plate 7 to rise under the buoyancy of water. The device uses the buoyancy generated on the plate body 701 after the water sample enters the storage bin 2 to make the plate body 701 drive the baffle wall 702 to rise, instead of using a motor to drive the plate body 701 and the baffle wall 702 to rise. The blocking plate 7 can rise or fall without consuming other electrical energy, thereby reducing overall energy loss.

[0031] A limiting hole 8 and a through hole 9 are provided on the plate body 701. In this embodiment, two limiting holes 8 are provided, which are distributed on both sides of the through hole 9. The stirring member passes through the plate body 701 through the through hole 9. The limiting rod 11 passes through the limiting hole 8. The limiting rod 11 is fixed in the sampling barrel 1. The plate body 701 is slidably connected to the limiting rod 11 through the limiting hole 8. The purpose of providing the two limiting rods 11 is to prevent the plate body 701 from rotating during the rising process, so as to ensure that the plate body 701 rises or falls stably.

[0032] A ferromagnet 10 is also fixed on the plate body 701, and a magnetic part 13 is installed at the corresponding position on the cover plate 12. In this embodiment, the magnetic part 13 is an electromagnet. The electromagnet is magnetic when powered on and can be magnetically attracted to the ferromagnet 10. When the power is turned off, the magnetism disappears and the magnetic attraction to the ferromagnet 10 is cancelled.

[0033] Before sampling, turn the device upside down and slide the blocking plate 7 along the inner wall of the sampling barrel 1 to the cover plate 12. Figure 4 In the state shown, the magnetic member 13 is energized, so that the magnetic member 13 and the ferromagnet 10 are magnetically attracted to each other, and the blocking plate 7 is fixed. At this time, the retaining wall 702 blocks the water inlet. When sampling, the sampling bucket 1 is placed in the water source. After the sampling bucket 1 reaches the specified depth, the power supply of the magnetic member 13 is cut off, and the magnetic attraction between the magnetic member 13 and the ferromagnet 10 is canceled. The blocking plate 7 falls under the action of its own gravity, that is, Figure 2 In the state shown, the retaining wall 702 releases the blockage of the water inlet, and the water sample enters the storage chamber 2 from the water inlet. After a certain amount of water sample enters, the buoyancy is generated on the plate 701. As the amount of water sample increases, the plate 701 is pushed up to the cover plate 12, that is, Figure 4In the state shown, the magnetic member 13 is energized continuously to fix the magnetic member 13 and the ferromagnetic body 10 by magnetic attraction, and the retaining wall 702 blocks the water inlet again to prevent the water sample from overflowing the sampling barrel 1, thereby completing the sampling process.

[0034] The stirring member includes a rotating shaft 4, a stirring blade 6 and a motor 5. The bottom of the rotating shaft 4 is rotatably mounted on the bottom plate of the sampling barrel 1 through a bearing. The other end of the rotating shaft 4 passes through the through hole 9 in sequence and penetrates the plate body 701 upward, and then passes through the cover plate 12 to be connected to the output end of the motor 5. The stirring blade 6 is fixedly mounted on the rotating shaft 4, and the motor 5 is fixedly mounted on the cover plate 12. The motor 5 is started to drive the rotating shaft 4 and the stirring blade 6 to rotate, and the water sample entering the storage bin 2 is stirred to simulate the flow state of the water sample in the water source, thereby ensuring the stability of the water sample, avoiding the precipitation of pollutants in the water sample, and ensuring that the water sample is in a dynamic state to simulate the flow state of the water sample, so as to improve the accuracy of the analysis results.

[0035] The temperature control component includes a heating wire 20 and a temperature sensor 19. The heating wire 20 is installed in the wall of the sampling barrel 1, and the temperature sensor 19 is fixed on the inner wall of the sampling barrel 1. It is used to detect the temperature of the water sample in the storage bin 2. The temperature in the storage bin 2 is adjusted by the heating wire 20 to ensure that the water sample is in a constant temperature state, reduce temperature changes, avoid reactions of substances in the water sample, and further improve the accuracy of the analysis results; when the temperature sensor 19 detects that the temperature in the storage bin 2 is too low, the power supply of the heating wire 20 is used to control the heating wire to heat, so that the water sample in the storage bin 2 remains in a stable state, and the rotation of the stirring blade 6 facilitates temperature conduction, so that the temperature of the water sample remains consistent.

[0036] A pull ring 16 is fixed on the top of the cover 12, and a steel wire rope 17 is connected to the pull ring 16. The steel wire rope 17 is provided with a scale. By pulling the steel wire rope 17, the device can be pulled, which is convenient for operation. The sampling depth can be determined by the scale on the steel wire rope 17.

[0037] A water outlet is provided at the bottom of the sampling barrel 1 for discharging water samples. A plug 15 is installed at the water outlet. When drainage is required, the plug 15 can be removed. When drainage is not required, the plug 15 blocks the water inlet, so that a closed space is formed inside the sampling barrel 1. A counterweight block 18 is provided at the bottom of the sampling barrel 1 to facilitate the sampling barrel 1 to enter the water source for sampling.

[0038] In this embodiment, a sealing plate 7 is slidably connected in the sampling barrel 1. The sealing plate 7 is lowered or raised by its own gravity or the buoyancy of the water sample, and can open or block the water inlet to control the sampling time. The rising or falling of the sealing plate 7 does not require other power consumption, which is energy-saving, environmentally friendly, and easy to operate. The sealing plate 7 is fixed by the magnetic part 13 and the ferromagnet 10 to ensure that no water samples of other depths enter the storage bin 2 during the sampling process, thereby ensuring the accuracy of the analysis results; a stirring blade 6 is rotatably installed in the storage bin 2 to keep the water sample in the storage bin 2 in a flowing state, simulating the flow conditions in the water source, preventing the pollutants in the water sample from precipitating, and ensuring the accuracy of the analysis results; a temperature sensor 19 is installed on the inner wall of the sampling barrel 1, and the temperature of the water sample in the storage bin 2 is adjusted by the heating wire 20. With the assistance of the stirring blade 6, the temperature of the water sample can be kept balanced, further improving the accuracy of the analysis results.
