Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0021] Example 1

[0022] A water source sampling device for environmental monitoring comprises a water tank 6 and water collection cylinders 7 arranged on two symmetrical sides of the water tank 6, wherein the water collection cylinder 7 and the water tank 6 are provided with a first water outlet 71 and a second water outlet 62 for water flow respectively on the side close to each other, and a pair of adjusting mechanisms for adjusting the opening and closing of the two water collection cylinders 7 are arranged above the water tank 6, wherein the adjusting mechanisms comprise a pressure plate, and preferably, a plurality of filter holes are arranged on the pressure plate, and the pressure plate matches the opening size of the water collection cylinder 7 so that the pressure plate is in close contact with the inner cavity of the water collection cylinder 7; a baffle 9 which can completely close the second water outlet 62 is arranged at the second water outlet 62 on the side of the water tank 6, and the baffle 9 is movably connected to the side of the water tank 6 and can control the opening and closing of the second water outlet 62.

[0023] Working principle: When the utility model is in use, the water tank 6 is placed in the water. Specifically, a supporting rod structure such as a telescopic rod 1 can be provided above the water tank 6 to send the water tank 6 into the water. In order to prevent excessive weeds and other debris in the water from being mixed into the water tank 6 during the process of the water tank 6 entering the water, the utility model uses a water intake cylinder 7 to take water in advance, and uses a pressure plate to filter and separate the debris in the water intake cylinder 7, so that relatively clean water is sent from the first water outlet 71 of the water intake cylinder 7 to the water tank 6 through the second water outlet 62, and then the baffle 9 is used to close the second water outlet 62 to seal the water tank 6, so that the relative sealing of the water in the water tank 6 after storage can be maintained, the water storage quality can be improved, and then the subsequent detection work efficiency and the accuracy of the detection results can be improved. It should also be noted that a detachable sealing door can be provided on the top or bottom of the water tank 6 to facilitate the subsequent discharge of water from the water tank 6 for detection;

[0024] Specifically:

[0025] The adjustment mechanism also includes an active link for driving the pressure plate to move up and down along the inner cavity of the water intake tube 7, and the active link includes a first active rod 4 connected to the pressure plate, and a second active rod 3 movably connected to the top of the first active rod 4, and an end of the second active rod 3 away from the first active rod 4 is movably connected to a driving mechanism for driving the second active rod 3 to move. In this way, before entering the water, the driving mechanism is used to drive the second active rod 3 to move, thereby driving the first active rod 4 connected thereto to move, thereby driving the pressure plate to move up and down in the water intake tube 7.

[0026] More specifically, the driving mechanism includes a telescopic rod 1 and a slider 2 disposed at the end of the telescopic rod 1, and one end of the second movable rod 3 away from the first movable rod 4 is movably connected to the slider 2. In this way, by driving the telescopic rod 1 downward to extend, the slider 2 can be driven to move downward, thereby causing one end of the second movable rod 3 to move downward, and the end connected to the first movable rod 4 to move upward, thereby causing the first movable rod 4 to move upward, thereby driving the pressing plate upward until it is separated from the water intake cylinder 7, thereby exposing the top opening of the water intake cylinder 7, so that water flows into the water intake cylinder 7, and then the telescopic rod 1 is retracted upward, driving the slider 2, the second movable rod 3, and the first movable rod 4 to move in the opposite direction to the previous movement, thereby driving the pressing plate downward. In this process, the pressing plate can isolate weeds and other debris in the water intake cylinder 7. In the process of pressing the pressing plate downward, the water flow can overflow from the side of the pressing plate and flow out from the first water outlet 71 into the water storage tank 6. Preferably, a plurality of filtering holes are provided on the pressing plate to facilitate water outflow.

[0027] In this embodiment, the adjustment mechanism further includes a limiting column 5, the bottom of which is connected to the water tank 6, and the slider 2 is slidably disposed on the limiting column 5. In this way, the slider 2 slides on the limiting column 5, and the stability of the slider 2 during movement is maintained, so that the movement of the second movable rod 3 and the first movable rod 4 is more stable, and the movement stability of the pressure plate is maintained.

[0028] In this embodiment, the bottom of the baffle plate 9 is connected to one side of the pressure plate, and the height of the baffle plate 9 is not less than the height of the second water outlet 62. Therefore, the baffle plate 9 can be used to seal the second water outlet 62, so that when the water collection tube 7 collects water, the water storage tank 6 remains in a relatively closed state, reducing the entry of impurities into the water storage tank 6.

[0029] In this embodiment, a receiving groove 61 is provided on a side of the water storage tank 6 close to the water intake cylinder 7. The receiving groove 61 is coaxially arranged with the baffle plate 9 and the width of the receiving groove 61 is consistent with the width of the baffle plate 9. In this way, the second water outlet 62 can be sealed or opened by using the baffle plate 9 in the process of moving up and down in the receiving groove 61.

[0030] In order to ensure the stability of the movement of the baffle 9, in the present embodiment, a limit spring 8 is provided on the top of the baffle 9, and the top of the limit spring 8 is connected to the top inner wall of the accommodating groove 61, so that under the action of the limit spring 8, the up and down movement of the baffle 9 can be limited to a certain extent, so that the baffle 9 can always be maintained in the vertical direction of the second water outlet 62, and then can accurately and stably enter the accommodating groove 61 to seal the second water outlet 62; in addition, the baffle 9 can also be set on the inner wall of the water tank 6, that is, the baffle 9 is moved up and down along the inner wall of the water tank 6 to seal the second water outlet 62.

[0031] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
