[0028] The utility model provides a water sampler. When in use, the revolving door 5 is first unlocked by rotating the fixing bolt 6 so that it can be rotated and opened, and then the sampling bottle 8 covered with the bottle cap 9 is inserted between the fixed base 7 and the driving rod 2, and then the revolving door 5 is closed and the fixing bolt 6 is rotated to fix the position of the revolving door 5 so that it will not open during the sampling process. Then the operator holds the end of the connecting rod 1 and extends its bottom end into the water body to be sampled, and then holds the end of the driving rod 2 to make the driving rod 2 move upward in the connecting rod 1, thereby driving the bottle cap 9 to move up and open. At this time, the water body to be sampled will flow into the sampling bottle 8 in the connecting rod 1 through the screen 4, and the screen 4 will isolate solid impurities from entering the sampling bottle 8. After the sampling is completed, the driving rod 2 is released, and the driving rod 2 will be reset under the action of the spring 3, driving the bottle cap 9 to move downward, thereby sealing the sampling bottle 8, and then the connecting rod 1 is moved out of the water body, and the sampling bottle 8 is taken out to complete the sampling operation.

[0029] Specifically, the connecting rod 1 is a hollow round rod with a square hollow box connected to its bottom end, and one side of the top end of the round rod extends outward and is provided with a handle 101, which is convenient for the operator to control the device by holding the handle 101.

[0031] Specifically, two upper and lower rotation grooves 103 are provided on one side of the square hollow box at the bottom of the connecting rod 1 , and the connecting rod 1 forms a rotation structure with one end of the revolving door 5 through the rotation groove 103 , which is conducive to the revolving door 5 being able to rotate around the rotation groove 103 .

[0032] Specifically, a card slot a202 is provided at the very end of the bottom of the driving rod 2, and the bottle cap 9 can slide into the card slot a202, which is beneficial when the bottle cap is inserted into the card slot a202, the driving rod 2 moving up and down can drive the bottle cap 9 to move, thereby completing the opening and sealing operations of the sampling bottle 8.

[0033] Specifically, the revolving door 5 is a rectangular panel with a plurality of flow holes 501 dug thereon, which is conducive to the excess water in the connecting rod 1 being discharged from the flow holes 501 when the connecting rod 1 is moved out of the water body.

[0034] Specifically, a block with a threaded groove 502 is provided on one side of the revolving door 5, and a fixing bolt 6 is provided in the threaded groove 502. The threaded groove 502 and the fixing bolt 6 constitute a threaded connection structure, and the fixing bolt 6 can be engaged with the fixing groove 104 on one side of the square hollow box at the bottom end of the connecting rod 1 by rotating, which is conducive to rotating the fixing bolt 6 to displace it in the threaded groove 502, so that the fixing bolt 6 can be inserted into the fixing groove 104, thereby fixing the position of the revolving door 5, so that it can protect the sampling bottle 8 placed inside the bottom end of the connecting rod 1 to prevent the sampling bottle 8 from being damaged during sampling.

[0035] Specifically, the fixed base 7 is installed and fixed in a square hollow box set at the bottom end of the connecting rod 1, and a card slot b701 is set in the fixed base 7, and the card block 801 set at the bottom end of the sampling bottle 8 can be inserted into the card slot b701, which is conducive to the sampling bottle 8 being fixed in the fixed base 7 to prevent the position of the sampling bottle 8 from changing during sampling, which affects the bottle cap 9 covering the top of the sampling bottle 8.

[0036] Specifically, a rubber ring 901 is provided inside the bottle cap 9, which is beneficial to improving the sealing performance of the bottle cap 9, so that when the bottle cap 9 covers the sampling bottle 8, the sample inside will not leak out easily, thereby improving the safety of the sampling water body.
