Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1

[0023] like Figure 1 As shown:

[0024] A water quality monitoring sampling device comprises a collecting barrel 1.

[0025] In this embodiment: the existing {public announcement number}: CN218330717U, discloses a water quality monitoring sampling device, this patent discloses a sampling tube, and the collecting barrel 1 in the present application document adopts the same technical means in this prior art. This technical means will not be described one by one here. For details about the improvement of this prior art, please refer to the disclosed technology below; to solve the technical problems existing in this prior art, as disclosed in the background technology above, "the operation process of the device is relatively cumbersome, and it is difficult to achieve the purpose of efficient sampling. At the same time, it is difficult for the device to filter impurities in the water body during sampling, which will lead to the difficulty of subsequent monitoring work and affect the monitoring results." In terms of combined use, this problem is obviously a real problem that exists and is relatively difficult to solve. In view of this, in order to solve the above problems, a bracket 2 and a pull rod 3 are added on this basis.

[0026] More specifically:

[0027] like Figure 1 - Figure 4 As shown:

[0028] In combination with the above content: it also includes a bracket 2, a pull rod 3, a force plate 4, a spring 5, a filter plate 6, a rubber gasket 7 and a support plate 8 arranged on one side of the collecting barrel 1, the inner surface of the collecting barrel 1 is fixedly provided with a bracket 2 that is slidably connected to the surface of the pull rod 3, and the surface of the pull rod 3 is also fixedly installed with a force plate 4 that is fixedly connected to one end of the spring 5, and the spring 5 is sleeved on the surface of the pull rod 3, and the other end of the spring 5 is fixedly connected to the surface of the filter plate 6, the filter plate 6 and the collecting barrel 1 form an integrated structure, and the pull rod 3 also penetrates the filter plate 6 and is fixedly connected to the surface of the rubber gasket 7, and the other side surface of the rubber gasket 7 is also fixedly connected to the support plate 8.

[0029] In this embodiment: when water sampling is required, the pull rod 3 can be held to put the collection bucket 1 and the filter plate 6 into the water and the position of the collection bucket 1 and the bracket 2 is always higher than the horizontal plane to prevent impurities on the water surface from entering the collection bucket 1. The collection bucket 1 will be subjected to the buoyancy from the water surface at this time, but under the pressing action of the pull rod 3, the pull rod 3 and the force plate 4 will compress the spring 5 above the filter plate 6. At the same time, the pull rod 3 will also make the rubber gasket 7 and the support plate 8 away from the position of the filter plate 6. Then, under the action of the water pressure, the water sample will be filtered through the filter plate 6 and enter the collection bucket 1 until the water level inside the collection bucket 1 and the water level outside rise. Then the pull rod 3 can be pulled up. At this time, the pull rod 3 will stretch the spring 5 through the force plate 4 and pull the support plate 8 and the rubber gasket 7 to move toward the filter plate 6 until the rubber gasket The rubber gasket 7 and the filter plate 6 form a tight connection and seal the filter plate 6. At this time, continue to pull the pull rod 3, and the collection barrel 1 that stores a certain amount of water sample will apply pressure to the rubber gasket 7 through the filter plate 6 and keep the two tightly connected. Then, when the pull rod 3 lifts the collection barrel 1 out of the water, the water sample in the collection barrel 1 will not leak under the pressure of the collection barrel 1. Then the filter plate 6 can be placed above a round-mouth container and the pull rod 3 can be gradually loosened. At this time, the spring 5 will gradually shrink and pull the pull rod 3 and the rubber gasket 7 and the support plate 8 and the filter plate 6 through the force plate 4 to separate. The filter plate 6 without the obstruction will release the water sample in the collection barrel 1 into the container, thereby completing the collection of the water sample. No additional operation is required during the collection process, and the purpose of filtering and sampling can be achieved only by pulling.

[0030] Going further:

[0031] In an optional embodiment, the collecting bucket 1 is in the shape of a funnel.

[0032] In this embodiment, the funnel-shaped collecting bucket 1 can filter the water through the filter plate 6 when the collecting bucket 1 is placed in the water body, and can also conveniently collect the water body after sampling.

[0033] Going further:

[0034] In an optional embodiment, the bracket 2 is arranged at an equal angle on the inner surface of the collection barrel 1, and a through hole matching the pull rod 3 is also opened on the surface of the bracket 2.

[0035] In this embodiment: the bracket 2 set at an equal angle on the inner surface of the collection bucket 1 can provide a stabilizing effect for the pulling of the pull rod 3, and can provide support for the pull rod 3 and the collection bucket 1 when the pull rod 3 is pressed and pulled.

[0036] Going further:

[0037] In an optional embodiment, the diameter of the force-bearing plate 4 is smaller than the diameter of the filter plate 6 .

[0038] In this embodiment: the force-bearing plate 4 which is smaller than the diameter of the filter plate 6 can prevent the force-bearing plate 4 from blocking the holes of the filter plate 6 when the pull rod 3 drives the force-bearing plate 4 to be pressed down, and under the obstruction of the spring 5, the water flow can smoothly pass through the filter plate 6 into the interior of the collection barrel 1.

[0039] Going further:

[0040] In an optional embodiment, circular through holes are evenly formed on the surface of the filter plate 6 .

[0041] In this embodiment: the through holes opened on the surface of the filter plate 6 can filter the impurities contained in the water through the filter plate 6 when the collection bucket 1 is placed in the water body, thereby ensuring the cleanliness of the water sample and ensuring that subsequent monitoring is more convenient.

[0042] Going further:

[0043] In an optional embodiment, the rubber gasket 7 and the supporting plate 8 are in the shape of a disc.

[0044] In this embodiment, the disc-shaped rubber gasket 7 and the support plate 8 can produce a stable sealing effect on the filter plate 6 when the pull rod 3 is pulled up, thereby ensuring that the water sample collected in the collection barrel 1 will not leak.

[0045] The working principle and use process of the utility model are as follows: when it is necessary to sample water, the pull rod 3 can be held to put the collection bucket 1 and the filter plate 6 into the water and the position of the collection bucket 1 and the bracket 2 can always be higher than the horizontal plane to prevent impurities on the water surface from entering the collection bucket 1. The collection bucket 1 will be subjected to the buoyancy from the water surface at this time, but under the pressing action of the pull rod 3, the pull rod 3 and the force plate 4 will compress the spring 5 above the filter plate 6. At the same time, the pull rod 3 will also make the rubber gasket 7 and the support plate 8 away from the position of the filter plate 6. Then, under the action of the water pressure, the water sample will be filtered through the filter plate 6 and enter the collection bucket 1 until the water level inside the collection bucket 1 and the water level outside rise. Then the pull rod 3 can be pulled up. At this time, the pull rod 3 will stretch the spring 5 through the force plate 4 and pull the support plate 8 and the rubber gasket 7 to move in the direction of the filter plate 6 until the water level inside the collection bucket 1 and the water level outside rise. Until the rubber gasket 7 and the filter plate 6 form a tight connection and the filter plate 6 is blocked, at this time, continue to pull the pull rod 3, and the collection bucket 1 that stores a certain amount of water samples will apply pressure to the rubber gasket 7 through the filter plate 6 and keep the two tightly connected. Then, when the pull rod 3 lifts the collection bucket 1 out of the water, the water sample in the collection bucket 1 will not leak under the pressure of the collection bucket 1, and then the filter plate 6 can be placed above a round-mouth container and the pull rod 3 can be gradually loosened. At this time, the spring 5 will gradually shrink and pull the pull rod 3 and the rubber gasket 7 and the support plate 8 and the filter plate 6 through the force plate 4 to separate them. The filter plate 6 without the obstruction will release the water sample in the collection bucket 1 into the container, thereby completing the collection of the water sample. No additional operation is required during the collection process, and the purpose of filtering and sampling can be achieved only by pulling.
