The existing sampling method is generally to take samples by sailing to the sampling point; however, for some river water sampling inspections where no boats are arranged, water can generally only be taken at the river bank. However, water sampling at the river bank can generally only sample surface water, and cannot sample deep water in the middle of the river. In response to the above problems in water sampling, I provide a sampling device for rapid water detection. Summary of the invention

[0003] In view of the deficiencies of the prior art, the present invention provides a sampling device for rapid detection of water bodies, which has the advantage of being able to perform multi-layer sampling in the center of the water area at the river bank, thereby solving the problems in the background technology.

Example 1

[0021] See also Figure 1 - Figure 3 The water rapid detection sampling device of the present invention comprises: Positioning assembly 1, the positioning assembly 1 comprises a positioning line 101, a positioning member 102 and a suspending member 103, the positioning member 102 is installed at the bottom of the positioning line 101, and the suspending member 103 and the positioning member 102 are used to make the positioning line 101 between the suspending member 103 and the positioning member 102 vertically located in the water; A sampling bottle 2, wherein a water intake hole 201 is provided on the sampling bottle 2, a water intake cover 203 is provided on the water intake hole 201, a driving component 202 for driving the water intake cover 203 is also provided in the sampling bottle 2, a mounting member 204 is provided on the sampling bottle 2, and a mounting hole 205 is provided on the mounting member 204; Several water intake points are arranged at equal distances on the positioning line 101 .

[0022] In the above solution, the suspension member 103 may be a drone, a casting rod 4 suspended on the water surface, or a float located on the water surface, etc.; When in use, by installing the sampling bottle 2 on the positioning line 101 in the water, the sampling bottle 2 can be placed in water of different depths, and the water collection points on the positioning line 101 can effectively control the spacing between the sampling bottles 2, thereby facilitating the collection of water samples at different water depths in the water; The sampling bottle 2 can automatically draw water from the water by opening the water intake cover 203 through the driving component 202 to allow water to flow into the bottle body, and closing the water intake hole 201 when the driving component 202 is started again to achieve water sampling.

[0023] Specifically, the mounting member 204 is provided with a notch 206 connected to the mounting hole 205 , and the edge of the notch 206 is rotatably connected to a closing block 207 for closing the notch 206 via a rotating shaft. The rotation of the closing block 207 can facilitate the mounting member 204 to be sleeved on the positioning line 101 .

[0024] Furthermore, a positioning block 104 is fixedly mounted on the water intake point on the positioning line 101 , and there are two mounting parts 204 on the sampling bottle 2 . The spacing between the two mounting parts 204 is equal to the length of the positioning block 104 , and the diameter of the mounting hole 205 is smaller than the diameter of the positioning block 104 .

[0025] In this embodiment, the sampling bottles 2 need to be installed on the positioning blocks 104 at different water collection points through the mounting members 204, so that multiple sampling bottles 2 can be effectively installed on the positioning line 101, and then the positioning line 101 is put into the water. Under the action of the positioning member 102 and the suspension member 103, the positioning line 101 between the positioning member 102 and the suspension member 103 is in a vertical state, that is, multiple sampling bottles 2 will be at different depths in the water, so that water samples of different depths can be effectively taken out of the water area at one time; In particular, in this embodiment, after the sampling bottle 2 is installed on the positioning line 101 on the shore, the sampling bottle 2 can be automatically moved to the center of the water area or to a suitable sampling point in the water area by a suspension member 103 such as a drone or an unmanned boat to sample water bodies at different depths; Example 2

[0026] See also Figure 4 and Figure 5 , which is different from the first embodiment, further includes a plurality of sampling lines 3 for guiding the sampling bottles 2 , and the ends of the plurality of sampling lines 3 are detachably connected to the positioning block 104 .

[0027] The device also includes a throwing rod 4 for throwing the positioning member 102 . The throwing rod 4 is provided with a throwing ring 5 at the end thereof. An opening 51 is provided on the adjacent side of the throwing ring 5 close to the throwing rod 4 .

[0028] A limiting frame 6 which is perpendicular to the center of the throwing ring 5 is provided on the throwing rod 4 .

[0029] By providing the limiting frame 6 and the throwing ring 5, it is convenient to throw the positioning member 102 so that the positioning line 101 is suspended to a suitable water intake position.

[0030] Preferably, the throwing rod 4 is a telescopic rod.

[0031] In this embodiment, it can be used on the river bank. When in use, the sampling line 3 needs to be installed on different water sampling points of the positioning line 101 according to the water depth of the water area and the water depth of the water sample to be taken, and then the positioning line 101 and the sampling line 3 are both plugged into the throwing ring 5, and then the positioning line 101 and the positioning member 102 are thrown into the water area through the throwing rod 4, and then under the action of gravity, the positioning line 101 and the sampling line 3 are both located vertically in the water; Then, the sampling line 3 is moved and pulled toward the opening 51 on the side, so that the sampling line 3 can pass through the opening 51 and move out of the throwing ring 5, and then the sampling bottle 2 is installed on different sampling lines 3 through the sampling piece, so that the sampling bottle 2 can be effectively slid to different sampling points for water sampling; compared with the first embodiment, this sampling method has the advantages of the first embodiment and has a simple structure, does not require the intervention of drones or unmanned boats, and can use a mechanical structure to enable manual sampling of multi-layer water bodies away from the river bank. In this sampling method, the hanging member 103 is the throwing ring 5 , that is, the positioning member 102 is located directly below the throwing ring 5 . Example 3

[0032] A float is arranged on the positioning line 101, so that the suspension member 103 is a float that can be detachably mounted on the positioning line 101; In this embodiment, the positioning member 102 can be thrown to further throw the positioning line 101 between the float and the positioning member 102 away from the river bank. Compared with the second embodiment, the distance between the sampling point in the sampling water area and the river bank can be effectively expanded; In Example 2 and Example 3: A closing rod 52 for closing the opening 51 is rotatably connected to the opening 51 of the throwing rod 4 via a rotating shaft. The rotating shaft is vertically arranged on the outside of the throwing ring 5, and one end of the closing rod 52 away from the rotating shaft is tilted downward.

[0033] It can effectively prevent the positioning line 101 and the sampling line 3 from being separated from the throwing ring 5 during the throwing process, and the downwardly inclined closing rod 52 can rotate under the lateral pulling and pressure of the sampling line 3, so that the required sampling line 3 can be separated from the throwing ring 5; In the second and third embodiments: the sampling bottle 2 is provided with a sensor 208, the sensor 208 is electrically connected to the driving component 202, and the sensor 208 can be a proximity switch, which automatically starts sampling after the sampling bottle 2 approaches the positioning block 104 on the positioning line 101; it has the characteristics of automatic sampling and can also ensure that the sampling bottle 2 slides to the corresponding water layer on the sampling line 3; In the first, second and third embodiments, the driving component 202 in the sampling bottle 2 can be a component such as an electric push rod that can enable the water intake cover 203 to open and close the water intake hole 201; The driving component 202 in the first embodiment can control the automatic start of the sampling bottle 2 by setting a power supply and a timer in the sampling bottle 2 to control the driving component 202, or a receiver for controlling the driving component 202 is built into the sampling bottle 2 to automatically start by remote control or the like.
