[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-3 A sampling device for water conservancy and environmental geology survey, comprising a gripping portion 1 and a sampling tube 2, wherein the gripping portion 1 and the sampling tube 2 are connected via a connecting tube 3, the outer surface of the connecting tube 3 is provided with scale lines, and the top of the sampling tube 2 is provided with a mounting port 4;

[0021] An opening and closing assembly is provided in the installation port 4, and the opening and closing assembly includes a fixing frame 51, a plugging core 52 and a spring 53. The fixing frame 51 is fixed inside the installation port 4, and an opening is provided on the fixing frame 51. The plugging core 52 is movably provided on the fixing frame 51. One end of the spring 53 is connected to the fixing frame 51, and the other end is connected to the plugging core 52. In the initial state, under the action of the spring 53, the plugging core 52 blocks the opening of the fixing frame 51, and at this time, the water flow cannot enter the interior of the sampling tube 2;

[0022] An actuator assembly is provided inside the sampling tube 2, and the actuator assembly includes a sealing tube 61, a sliding plug 62, a push rod 63 and a second spring 64. The sealing tube 61 is fixed inside the sampling tube 2, and the sliding plug 62 is sealingly and slidably connected to the inner surface of the sealing tube 61. One end of the push rod 63 is fixedly connected to the sliding plug 62, and the other end extends to the outside of the sealing tube 61. The push rod 63 is arranged opposite to the plugging core 52. One end of the second spring 64 is connected to the inner surface of the sealing tube 61, and the other end is connected to the sliding plug 62. The sealing tube 61 is connected to one end of the connecting pipe 3. After the gas enters the sealing tube 61, it can push the sliding plug 62 to move, so that the sliding plug 62 drives the push rod 63 to move. When the push rod 63 moves, it can push the plugging core 52, so that the plugging core 52 no longer blocks the opening. At this time, the water flow can enter the interior of the sampling tube 2 through the opening, so as to sample the water source.

[0023] A trigger assembly is provided on the gripping portion 1, and the trigger assembly includes a cavity 71, a slide plate 72, a pressure rod 73 and a spring three 74. The cavity 71 is opened inside the gripping portion 1, and the slide plate 72 is sealingly and slidably connected inside the cavity 71. One end of the pressure rod 73 is fixedly connected to the slide plate 72, and the other end extends to the outside of the cavity 71. One end of the spring three 74 is connected to the inner wall of the cavity 71, and the other end is connected to the slide plate 72. The cavity 71 is connected to the other end of the connecting pipe 3. The staff presses the pressure rod 73 to make the pressure rod 73 drive the slide plate 72 to move. When the slide plate 72 moves, the air in the cavity 71 can be pressed into the interior of the sealing tube 61 through the connecting pipe 3.

[0024] The specific working principle of the utility model is as follows:

[0025] When the water conservancy and environmental geological survey sampling device proposed by the utility model is in use, in the initial state, under the action of the spring 1 53, the plug 52 blocks the opening of the fixing frame 51, and the water flow cannot enter the interior of the sampling tube 2. When sampling water, the staff first puts the sampling tube 2 into the water to make the sampling tube 2 descend in the water. In this process, the staff controls the descending depth of the sampling tube 2 through the scale line on the connecting pipe 3. When the sampling tube 2 reaches the position where sampling is required, the staff presses the pressure rod 73, so that the pressure rod 73 drives the slide plate 72 to move, and the slide plate 72 can move the air The air in the cavity 71 is pressed into the interior of the sealing tube 61 through the connecting tube 3. After the gas enters the sealing tube 61, it can push the sliding plug 62 to move, so that the sliding plug 62 drives the push rod 63 to move. When the push rod 63 moves, it can push the plugging core 52, so that the plugging core 52 no longer blocks the opening. At this time, the water flow can enter the interior of the sampling tube 2 through the opening, so as to sample the water source. After the sampling is completed, the staff can directly pull the sampling tube 2 out of the water through the connecting tube 3. Based on the above process, the staff can use the trigger component and the execution component to flexibly sample water sources at different depths, and the operation is convenient.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
