[0002] As is well known, in the field of environmental science, water sampling devices are needed to test and analyze water quality. However, when performing stratified sampling, existing water sampling devices require repeatedly raising and lowering a single sampling container in the water to collect water samples from different layers. As a result, the convenience of water sampling devices in performing stratified sampling still needs to be improved. To this end, a water sample stratification sampling device is proposed. Utility Model Content

[0003] The purpose of this invention is to provide a water sample stratification collection device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a water sample stratification collection device, comprising: a sampling mechanism and a positioning mechanism;

[0005] The sampling mechanism includes several water storage tanks, which are connected side-by-side by screws. Each water storage tank has an inlet pipe connected to one side, and a solenoid valve is fixedly installed on the inlet pipe. A hollow shell is fixedly connected to the top of the uppermost water storage tank. A first shell is connected to one side of the hollow shell, and a second shell is evenly connected to one side of the first shell. One side of the second shell is fixedly connected to the inlet pipe. A through hole is provided at the top of the second shell. A hollow waterproof rope is fixedly connected to the top of the hollow shell. Several conductive wires pass through the hollow waterproof rope. A controller is installed at one end of each conductive wire, and the controller's output terminal is fixedly connected to the conductive wire. The end of the conductive wire furthest from the controller passes through the hollow shell, the first shell, and the second shell, and extends out from the through hole. The solenoid valve's input terminal is fixedly connected to the conductive wire.

[0006] The positioning mechanism includes a plate fixedly installed on the water's edge, with the top of the plate fixedly connected to the housing of the controller.

[0007] By adopting the above technical solution, after several stacked and fixed water storage tanks are placed in the water, the water storage tanks can be moved to a designated water level by pulling the hollow waterproof rope. This allows the controller to activate the solenoid valve on the corresponding water storage tank via a wire, allowing water at that level to enter the water storage tank. After closing the solenoid valve, the water storage tank is moved to another water level, and the solenoid valve on another corresponding water storage tank is activated. By operating in sequence, water samples from different levels can be collected at once.

[0010] Preferably, a sealing ring is fixedly connected to the side of the second housing near the through hole, and the sealing ring is fixedly fitted onto the conductive wire.

[0011] By adopting the above technical solution, water can be prevented from flowing into the interior of the second housing through the gaps in the conductive wires and through holes.

[0012] Preferably, one end of the water inlet pipe is threadedly connected to a pipe cap, and a handle is fixedly connected to the outside of the pipe cap.

[0013] By adopting the above technical solution, the water inlet pipe can be sealed when not in use, preventing external dust from entering the water storage tank.

[0014] Preferably, a bracket is fixedly connected to the top of the plate, and a bolt is threaded inside the bracket. The bottom end of the bolt is rotatably connected to a clamping plate for clamping the hollow waterproof rope through a bearing. Both sides of the clamping plate are movably connected to the bracket.

[0015] By adopting the above technical solution, after the plate is fixed on the ground, the clamping plate can be moved downward by tightening the bolts, so that the hollow waterproof rope can be clamped by the clamping plate.

[0016] Preferably, the bracket has symmetrically formed grooves on its inner side, and a slider is slidably connected to the inner wall of the groove, with one side of the slider being fixedly connected to the clamping plate.

[0017] By adopting the above technical solution, the clamping plate can maintain stable linear movement under the action of bolts.

[0018] Preferably, a support plate is fixedly connected to the top of the plate, and the support plate is in close contact with the bottom of the hollow waterproof rope.

[0019] By adopting the above technical solution, the stability of the hollow waterproof rope after it is clamped can be further improved.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] This water sample stratification sampling device, through its sampling mechanism, allows several water tanks to be submerged in water. The controller then sequentially controls the corresponding solenoid valves via conductive wires, enabling the automatic opening and closing of the inlet pipes on the corresponding water tanks. This facilitates the collection of water samples from different layers from the various water tanks. This design effectively enhances the convenience of stratified sampling in the water sample collection device. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-4 This utility model provides a technical solution: a water sample stratification collection device, comprising: a sampling mechanism 1 and a positioning mechanism 2;

[0029] First, in order to move the stacked and fixed water tanks 10 to a designated water level by pulling the hollow waterproof rope 17 after they are placed in the water, the controller 19 can activate the solenoid valve 12 on the corresponding water tank 10 via a wire, allowing water at that level to enter the water tank 10. After closing the solenoid valve 12, the water tank 10 is moved to another water level, and the solenoid valve 12 on another corresponding water tank 10 is activated. This sequential operation allows for the simultaneous collection of water samples from different levels. The sampling mechanism 1 includes several water tanks 10, with adjacent sides of the tanks 10 fixedly connected by screws. One side of each water tank 10 is connected to a water inlet pipe 11, and a solenoid valve 12 is fixedly installed on the water inlet pipe 11. A hollow shell 13 is fixedly connected to the top of the uppermost water storage tank 10. A first shell 14 is connected to one side of the hollow shell 13. A second shell 15 is evenly connected to one side of the first shell 14. One side of the second shell 15 is fixedly connected to the water inlet pipe 11. A through hole 101 is opened on the top of the second shell 15. A hollow waterproof rope 17 is fixedly connected to the top of the hollow shell 13. Several conductive wires 18 pass through the inside of the hollow waterproof rope 17. A controller 19 is provided at one end of the conductive wire 18. The electrical control output end of the controller 19 is fixedly connected to the conductive wire 18. The end of the conductive wire 18 away from the controller 19 passes through the inside of the hollow shell 13, the first shell 14 and the second shell 15 respectively and extends out from the through hole 101. The electrical control input end of the solenoid valve 12 is fixedly connected to the conductive wire 18.

[0030] Secondly, in order for the plate 20 to be fixed on the ground at the water's edge, and for the clamping plate 23 to move downward by tightening the bolts 22, thereby clamping the hollow waterproof rope 17, the positioning mechanism 2 includes a plate 20 fixedly installed at the water's edge. The top of the plate 20 is fixedly connected to the housing of the controller 19. A bracket 21 is fixedly connected to the top of the plate 20. Bolts 22 are threaded inside the bracket 21. The bottom end of the bolts 22 is rotatably connected to a bearing for clamping the hollow waterproof rope 17. The clamping plate 23 of the rope 17 is movably connected to the bracket 21 on both sides. In order to enable the clamping plate 23 to maintain stable linear movement under the action of the bolt 22, the inner side of the bracket 21 is symmetrically provided with a sliding groove 24, and a slider 25 is slidably connected to the inner side wall of the sliding groove 24. One side of the slider 25 is fixedly connected to the clamping plate 23. In order to further improve the stability of the hollow waterproof rope 17 after it is clamped, a support plate 26 is fixedly connected to the top of the plate 20, and the support plate 26 is close to the bottom of the hollow waterproof rope 17.

[0031] Furthermore, in order to ensure that the water tank 10 sinks smoothly into the water, a weight 104 is fixedly connected to the bottom of one of the water tanks 10 located at the bottom. In order to prevent water from flowing into the second housing 15 from the gap between the conductive wire 18 and the through hole 101, a sealing ring 16 is fixedly connected to the side of the second housing 15 near the through hole 101, and the sealing ring 16 is fixedly fitted onto the conductive wire 18. In order to seal the water inlet pipe 11 when not in use and prevent external dust from entering the water tank 10, a pipe cap 102 is threaded to one end of the water inlet pipe 11, and a handle 103 is fixedly connected to the outside of the pipe cap 102.

[0032] Based on the above technical solution, the working steps of this solution are summarized as follows: In use, after several stacked and fixed water storage tanks 10 are placed in the water, the water storage tanks 10 can be moved to a designated water level by pulling the hollow waterproof rope 17. This allows the controller 19 to activate the solenoid valve 12 on the corresponding water storage tank 10 via a wire, thereby allowing water at that level to enter the water storage tank 10. After closing the solenoid valve 12, the water storage tank 10 is moved to another water level. At this time, the solenoid valve 12 on another corresponding water storage tank 10 is activated. By operating in sequence, water samples from different levels can be collected at once.
