[0002] Hydrogeological survey plays an important role in the fields of water resource development, utilization and environmental protection, especially in sampling and analyzing water quality in different waters and at different depths, which can provide a scientific basis for water quality assessment, water pollution control and groundwater resource management. Traditional water source sampling devices usually have a simple structure and a single function, making it difficult to accurately sample water bodies at multiple levels and depths. In addition, during the water sampling process, they are easily impacted by lateral water flow, causing the sampling device to shift and affecting the accuracy of the sampling. In addition, after the sampling is completed, the existing sampling device has a complex structure and a large weight, resulting in large resistance during the lifting process, making it difficult to operate, consuming a lot of manpower and time, which is not conducive to efficient application in actual survey work.

DETAILED DESCRIPTION

[0025] 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 the embodiments.

[0026] In one embodiment, referring to Figures 1 to 10, a water source sampling and detection device for hydrogeological exploration, comprising a sampling shell 3, both side walls of the sampling shell 3 are provided with a reaction shell 9, the bottom ends of the two reaction shells 9 are provided with the same counterweight 1, and the interior of the reaction shell 9 is filled with reactants; a plurality of partition plates 30 are provided inside the sampling shell 3, and the partition plates 30 divide the interior of the sampling shell 3 into a transition chamber 26 and a plurality of sampling chambers 29, the transition chamber 26 is located at the top of the interior of the sampling shell 3, a side wall of the transition chamber 26 is provided with a water inlet hole 25, a side wall of the sampling chamber 29 is provided with a water inlet hole 14, and the interiors of the transition chamber 26 and the sampling chamber 29 are both provided with a sealing mechanism 32 for blocking the openings of the water inlet hole 14 and the water inlet hole 25; a side wall of the transition chamber 26 is provided with a water inlet hole 419, a side of the reaction shell 9 close to the sampling shell 3 is provided with a water inlet hole 316, and the reaction shell 9 is provided with a sealing mechanism 32 for blocking the openings of the water inlet hole 14 and the water inlet hole 25. The interior and the interior of the transition chamber 26 are connected through the water inlet hole three 16 and the water inlet hole four 19; a fixed seat 6 is provided on the top of the sampling shell 3, and a depth detector 25 is installed inside the fixed seat 6. An air bag 7 made of flexible material is provided at the top opening of the fixed seat 6, and air inlet holes 24 are opened on both side walls of the fixed seat 6; an air duct 15 is provided at the top of the reaction shell 9, and the interior of the reaction shell 9 is connected with the interior of the fixed seat 6 through the air duct 15 and the air inlet hole 24; a gear ring 10 is movably provided on the top of the sampling shell 3, and two toggle side wings 20 are provided at the bottom of the gear ring 10, and two shielding parts 22 are provided on the top of the gear ring 10, a driving gear 21 is movably installed on one side of the fixed seat 6, and the circumference of the driving gear 21 is meshed with the circumference of the gear ring 10, and a driving motor 23 for driving the driving gear 21 to rotate is provided on one side of the fixed seat 6.

[0027] When in use, the sampling shell 3 is lowered into the water area to be sampled, and the depth detector 25 detects the diving depth of the sampling shell 3. When reaching different depths, the sealing mechanism 32 in the sampling chamber 29 at different positions is removed from the opening of the water inlet hole 1 4, so that the water samples of the water areas of different depths flow into the sampling chamber 29 through the water inlet hole 1 4, thereby realizing the sampling of water areas of different depths. After the sampling is completed, the sealing mechanism 32 in the transition chamber 26 is removed from the opening of the water inlet hole 2 5. At this time, the water flows into the transition chamber 26 through the water inlet hole 2 5. The water in the transition chamber 26 enters the reaction shell 9 through the water inlet hole 4 19 and the water inlet hole 3 16, and the water reacts with the reactants in the reaction shell 9 to generate gas, which is injected into the fixed seat 6 and the air bag 7 through the air guide pipe 15 and the air inlet hole 24. As the reaction proceeds, the air bag 7 is inflated and expanded, and the driving motor 23 drives the driving gear 21 to rotate. Through the meshing of the driving gear 21 and the gear ring 10, the driving gear ring 10 rotates. As the gear ring 10 rotates, the side wing 20 is moved to the opposite The shell 9 is toggled so that the reaction shell 9 and the counterweight 1 are separated from the sampling shell 3 and fall off. At this time, the opening of one end of the air guide tube 15 and the opening of the air inlet 24 are staggered. At the same time, as the gear ring 10 rotates, the shielding component 22 shields the opening of the air inlet 24. That is, in the process of the sampling shell 3 diving for sampling, the counterweight 1 and the reaction shell 9 increase the weight of the sampling shell 3 diving, ensuring that the sampling shell 3 can dive quickly and vertically, and preventing the sampling shell 3 from being impacted by the lateral water flow during the diving process. However, a large deviation occurs and the target water area cannot be sampled. After the stratified sampling is completed, the gas generated by the reaction between water and the reactants in the reaction shell 9 can be used to fill the airbag 7 to increase the buoyancy of the fixed seat 6 and the sampling shell 3. After the airbag 7 is filled, the reaction shell 9 and the counterweight block 1 are separated from the sampling shell 3, further reducing the resistance of the sampling shell 3 when lifting after sampling is completed, so that the sampling shell 3 can be quickly and labor-savingly lifted to the water surface after sampling is completed. It is easy to use and has a compact structure.

[0028] As a preferred embodiment of the present invention, the sealing mechanism 32 includes a telescopic component 27 installed on the inner wall of the sampling shell 3, and a sealing plug 28 is provided at one end of the piston rod of the telescopic component 27. The outer diameter of the sealing plug 28 is adapted to the inner diameter of the water inlet hole 1 4 and the water inlet hole 2 5. The position of the sealing plug 28 can be adjusted by pushing the telescopic component 27, thereby controlling the sealing plug 28 to block and seal the water inlet hole 1 4 or the water inlet hole 2 5.

[0029] As a preferred embodiment of the present invention, a lifting rope 2 is arranged on the top of the fixing seat 6 .

[0030] As a preferred embodiment of the present invention, both side walls of the sampling shell 3 are provided with spaced connecting side wings 31, and a vertically arranged separation groove 12 is provided on one side of the reaction shell 9 close to the sampling shell 3, and a side wall of the separation groove 12 is provided with spaced limiting grooves 11, and the position of the limiting grooves 11 is adapted to the position of the connecting side wings 31.

[0031] As a preferred embodiment of the present invention, a positioning hole 13 is formed on the top of the reaction shell 9 , and a through hole is formed on the connecting wing 31 located on the top of the reaction shell 9 , and the opening position of the through hole corresponds to the opening position of the positioning hole 13 .

[0032] As a preferred embodiment of the present invention, two connecting ropes 8 are arranged on the top of the airbag 7, and a positioning pin 18 is arranged at one end of the two connecting ropes 8 away from the airbag 7. The outer diameter of the positioning pin 18 is adapted to the inner diameter of the positioning hole 13 and the opening of the perforation. Before the sampling shell 3 dives, the two reaction shells 9 are respectively placed on both sides of the sampling shell 3, the connecting side wings 31 are aligned with the top opening of the separation groove 12, the reaction shell 9 is lifted so that the connecting side wings 31 are located in the separation groove 12, and then the counterweight block 1 is rotated so that the connecting side wings 31 move into the limiting groove 11, that is, the reaction shell 9 and The counterweight 1 is assembled, and the positioning pin 18 is inserted and penetrated into the positioning hole 13 and the through hole to position the reaction shell 9 and the connecting side wing 31 to prevent the reaction shell 9 from falling off during the diving of the sampling shell 3. After the airbag 7 is inflated and expanded, the connecting rope 8 is pulled to lift the positioning pin 18 and move it out of the positioning hole 13. At this time, the reaction shell 9 is moved by moving the side wing 20 to move the connecting side wing 31 into the separation groove 12. At this time, the reaction shell 9 and the counterweight 1 automatically move downward under the action of their own gravity until they are separated and fall off, thereby ensuring the stability of use.

[0033] As a preferred embodiment of the present invention, a shielding component 14 is sleeved on one end of the air duct 15 away from the reaction shell 9, and the outer diameter of the shielding component 14 is larger than the inner diameter of the opening of the air inlet hole 24. When the opening of the air duct 15 is staggered with the opening of the air inlet hole 24, the shielding component 14 blocks the opening of the air inlet hole 24 until the shielding component 22 blocks the opening of the air inlet hole 24, thereby effectively preventing water from entering the fixing seat 6 through the air inlet hole 24.

[0034] 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 according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
