Description

Technical Field

[0001] This utility model relates to the field of water source sampling technology, specifically to an environmental water source assessment and sampling device. Background Technology

[0002] Humans cannot live without water, and the quality of drinking water is closely related to human health. With the development of society and the economy, scientific progress and the improvement of people's living standards, people's requirements for the quality of drinking water are constantly increasing, and therefore the testing of water sources is becoming more scientific and frequent.

[0003] A search of the China Patent Network revealed an existing patent (publication number: CN215374613U) that discloses an environmental water source assessment sampling device. This device, through the cooperation of a limiting block, a traction rope, a limiting plate, a movable groove, a movable rod, a baffle, a first spring, a push block, and a sealing plug, avoids the problem of difficulty in accurately controlling the sampling depth that often exists in traditional conduit extraction methods.

[0004] However, the above-mentioned technical solution still has certain defects. The device introduces water and performs sampling through the cooperation between the first spring and the sealing plug. However, this design has a significant limitation: during the sampling process, it can only sample water at a single depth. This means that in order to conduct a comprehensive and accurate assessment of the entire water source, the operator has to perform multiple samplings to cover water at different depths. This repetitive sampling not only consumes time and effort but may also increase the complexity of the operation and the possibility of error. Therefore, an environmental water source assessment sampling device is proposed. Utility Model Content

[0005] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention provides an environmental water source assessment sampling device capable of simultaneously sampling water sources at multiple depths, greatly improving sampling efficiency and accuracy.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an environmental water source assessment sampling device, comprising a hollow column, wherein a sampling component is provided on the outside of the hollow column;

[0007] The sampling assembly includes a circular plate slidably connected to the upper end of the inner wall of the hollow column. A vertically downward long shaft is fixed to the bottom end of the circular plate. The outer wall of the long shaft has four sets of guide blocks arranged in a stepped circular array. Four storage boxes are fixed to the outer wall of the hollow column from top to bottom. Sampling bottles are placed inside the storage boxes. A guide tube fixed to the hollow column is inserted into the top of the sampling bottle. One end of the guide tube extends horizontally into the hollow column. A sealing plug is horizontally slidably assembled inside the hollow column through a sliding structure. The sealing plug is adapted to the guide tube. A fixing column is fixedly connected to the end of the sealing plug away from the guide tube. An inclined groove adapted to the guide blocks is opened in the fixing column.

[0008] The circular plate is also connected to a driving assembly, which is used to drive the circular plate to slide axially within the hollow column. When the driving assembly drives the circular plate to slide axially, the long axis slides axially within the hollow column synchronously with the circular plate. The guide block drives the fixed column to move horizontally through sliding cooperation with the inclined groove, so as to drive the sealing plug to slide and achieve the sealing or unsealing of the guide tube.

[0009] As a preferred technical solution, handles are rotatably connected to both sides of the upper end of the curved outer wall of the hollow column. The ends of the two sets of handles extend into the interior of the hollow column, and a rope is wrapped around one end of the outer wall of the handle. The top end of the rope is fixed to the circular plate.

[0010] As a preferred technical solution, a reset spring is installed at the top of the four sets of circular plates, and the top of the reset spring is fixed to the top of the inner wall of the hollow column.

[0011] As a preferred technical solution, a guide shaft is sleeved on the lower end of the outer wall of the long shaft, the bottom end of the guide shaft is fixed to the lower end of the inner wall of the hollow column, and a spring telescopic rod that abuts against the bottom end of the long shaft is installed inside the guide shaft.

[0012] As a preferred technical solution, all four sets of storage boxes are equipped with electromagnetic valves at the bottom, and the outer wall of the hollow column is hollow.

[0013] As a preferred technical solution, movable rods are connected to both sides of the outer wall of the fixed column, and a support block is slidably connected to the side of the movable rod away from the fixed column. The support block is fixed to the hollow column.

[0014] In summary, the present invention has the following main advantages:

[0015] This invention allows the fixed column to move away from the guide tube by rotating the handles on both sides. At this time, the water source enters the sampling bottle through the guide tube for sampling, thereby achieving the purpose of simultaneous sampling of the sampling bottles in the four sets of storage boxes. It effectively realizes the sampling of water sources at different depths, avoiding the limitation of traditional devices that can only sample water sources at a single depth. The operator only needs to adjust the immersion depth of the hollow column in the water to use this device to complete the sampling of water sources at multiple depths at one time, which greatly improves the sampling efficiency and accuracy.

[0016] This invention uses a return spring to reset the circular plate, and the fixed column and sealing plug will automatically reset under the action of the return spring. The sealing plug fits tightly against the inner wall of the guide tube, preventing leakage of water inside the sampling bottle and ensuring the accuracy of sampling. Finally, the operator opens the solenoid valve to drain the water inside the sampling bottle, facilitating subsequent testing and analysis of the water inside the sampling bottle, further improving the practicality and flexibility of the device.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0025] The embodiments of this utility model will be described below based on its overall structure.

[0026] An environmental water source assessment sampling device, such as Figure 1-5 As shown, it includes a hollow column 100, and a sampling component 200 is provided on the outside of the hollow column 100;

[0027] The sampling assembly 200 includes a circular plate 210 slidably connected to the upper end of the inner wall of the hollow column 100. A vertically downward long shaft 220 is fixed to the bottom end of the circular plate 210. The outer wall of the curved surface of the long shaft 220 has four sets of guide inclined blocks 230 arranged in a stepped circular array. Four sets of storage boxes 240 are fixed to the outer wall of the curved surface of the hollow column 100 from top to bottom. Sampling bottles 250 are provided inside the storage boxes 240. The top of the sampling bottles 250 is inserted into the hollow column 100. A fixed flow guide 260 has one end extending horizontally into the hollow column 100. A sealing plug 270 is horizontally slidably assembled inside the hollow column 100 through a sliding structure. The sealing plug 270 is adapted to the flow guide 260. A fixing column 280 is fixedly connected to the end of the sealing plug 270 away from the flow guide 260. A groove 281 adapted to the guide inclined block 230 is opened in the fixing column 280.

[0028] The circular plate 210 is also connected to a driving assembly, which is used to drive the circular plate 210 to slide axially within the hollow column 100. When the driving assembly drives the circular plate 210 to slide axially, the long shaft 220 slides axially within the hollow column 100 synchronously with the circular plate 210. The guide block 230 drives the fixed column 280 to move horizontally through sliding cooperation with the inclined groove 281, so as to drive the sealing plug 270 to slide and realize the sealing or unsealing of the guide tube 260.

[0029] The drive assembly includes handles 2910 symmetrically rotatably connected to the curved outer wall of the hollow column 100. The ends of both sets of handles 2910 extend into the interior of the hollow column 100, and a rope 2920 is wound around one end of the outer wall of the handle 2910. The top of the rope 2920 is fixed to the circular plate 210. The top of the four sets of circular plates 210 is equipped with a return spring 2930, and the top of the return spring 2930 is fixed to the top of the inner wall of the hollow column 100.

[0030] During use, the operator lowers the hollow column 100 into the water using the handle 2910 until all four storage boxes 240 are completely submerged. Then, by rotating the handles 2910 on both sides, the operator causes the rope 2920 to wind up. Since the rope 2920 is fixed to the circular plate 210, the circular plate 210, via the long shaft 220, drives the four guide blocks 230 to move downwards synchronously. The guide blocks 230 engage with the inclined groove 281. As the guide blocks 230 continue to move downwards, they push against the inner wall of the inclined groove 281, thus advancing the flow of energy. The fixed column 280 drives the sealing plug 270 to move away from the guide pipe 260. At this time, the water source enters the sampling bottle 250 through the guide pipe 260 for sampling, thereby achieving the purpose of simultaneous sampling of the sampling bottles 250 in the four sets of storage boxes 240. This effectively realizes the sampling of water sources at different depths, avoiding the limitation of traditional devices that can only sample water sources at a single depth. The operator only needs to adjust the immersion depth of the hollow column 100 in the water to use this device to complete the sampling of water sources at multiple depths at one time, which greatly improves the sampling efficiency and accuracy.

[0031] After sampling is completed, release handle 2910 to allow return spring 2930 to drive circular plate 210 to reset. Fixed column 280 and sealing plug 270 will automatically reset under the action of return spring 2930. Sealing plug 270 fits tightly against the inner wall of guide tube 260, preventing water leakage from inside sampling bottle 250 and ensuring sampling accuracy. Finally, the operator opens solenoid valve 241 to drain water from inside sampling bottle 250, facilitating subsequent testing and analysis of the water inside sampling bottle 250, further improving the practicality and flexibility of the device.

[0032] Please refer to this carefully. Figures 1 to 3 Each of the four storage boxes 240 is equipped with an electromagnetic valve 241 at the bottom, and the outer wall of the hollow column 100 is hollow.

[0033] By setting up the solenoid valve 241, the discharge of water samples in the sampling bottle 250 can be flexibly controlled, which facilitates subsequent experimental analysis.

[0034] Please refer to this carefully. Figure 2 and Figure 3 A guide shaft 2940 is sleeved on the lower end of the outer wall of the long shaft 220. The bottom end of the guide shaft 2940 is fixed to the lower end of the inner wall of the hollow column 100, and a spring telescopic rod 2950 that abuts against the bottom end of the long shaft 220 is installed inside the guide shaft 2940.

[0035] By setting the guide shaft 2940 and the spring telescopic rod 2950, ​​the up and down movement of the long shaft 220 is guided and supported. At the same time, the setting of the spring telescopic rod 2950 allows the long shaft 220 to be buffered when it moves down to the bottom, avoiding damage to the device caused by hard impact and improving the service life of the device. In addition, the cooperation between the guide shaft 2940 and the spring telescopic rod 2950 also makes the sampling component 200 more stable and rapid when resetting, further improving the efficiency and stability of the sampling operation.

[0036] Please refer to this carefully. Figure 4 and Figure 5 Movable rods 290 are connected to both sides of the outer wall of the fixed column 280. A support block 291 is slidably connected to the side of the movable rod 290 away from the fixed column 280. The support block 291 is fixed to the hollow column 100.

[0037] The cooperation between the moving rod 290 and the support block 291 makes the fixed column 280 more stable during movement, avoiding deviation or shaking, thereby ensuring that the sealing plug 270 can be accurately slidably connected to the inner wall of the guide tube 260, so as to achieve smooth water sampling.
