Description

Technical Field

[0001] This invention belongs to the field of water sample collection technology, specifically relating to a dispensing water sample collection device and its usage method. Background Technology

[0002] In environmental quality analysis, water sample analysis of rivers is a crucial step. Water sampling is necessary for river water quality analysis. Existing sampling technologies employ various structures, all based on the principle of collecting one sample at a time, with multiple samplings performed. For example, Chinese invention patent application CN202211123680.7, entitled "River Wastewater Sampling Device," discloses a sampling device including a retractable support connecting a sampling bottle to a traction rope. The sampling bottle comprises a body and a cap, with a gravity block inside the body and an air inlet on the cap. Its working principle is as follows: the sampling bottle falls to the bottom of the river under gravity; the cap opens from the bottle body due to buoyancy, allowing wastewater to enter; then the cap is closed, sealing the wastewater inside the bottle, completing the sampling. However, this device can only collect water samples from a fixed location (the river bottom), and cannot collect samples from multiple locations at different heights; furthermore, the amount of water collected each time is limited, failing to meet the needs of conducting multiple simultaneous testing experiments. Summary of the Invention

[0003] To address the aforementioned shortcomings, the present invention aims to provide a dispensing water sample collection device that can quickly and conveniently collect water samples from different heights, increase the amount of water collected, and meet the needs of conducting multiple testing experiments simultaneously.

[0004] This invention provides a dispensing water sample collection device, comprising a sampling section, a lifting drive section, and a dispensing section. The sampling section is used to draw in water samples and includes a sampling chamber and a conveying component that are interconnected. The moving end of the lifting drive section is connected to the sampling section and is used to drive the sampling section to move up and down. The dispensing section includes a dispensing tray and a rotating drive component. The rotating drive component is connected to the fixed end of the lifting drive section and is used to drive the dispensing tray to rotate. The dispensing tray has multiple independent receiving cavities distributed along its circumference. Each receiving cavity has a water inlet hole for communicating with the conveying component, which can store the water sample after it enters.

[0005] Preferably, the upper end of the sampling chamber is provided with an annular groove, and the moving end of the lifting drive unit is provided with an annular protrusion, which is slidably disposed in the annular groove.

[0006] Preferably, the conveying component includes a corrugated pipe and a water pump that are interconnected.

[0007] Preferably, it further includes a support portion disposed between the fixed end of the lifting drive unit and the dispensing unit, the support portion having a through hole for connecting the water inlet and the conveying component.

[0008] Preferably, the top of the through hole is provided with a first waterproof gasket and a first magnetic gasket from top to bottom, and the water inlet is provided at the bottom of the receiving cavity, wherein a second magnetic gasket and a second waterproof gasket are provided from top to bottom.

[0009] Preferably, the receiving cavity includes a water storage cavity and a water pushing cavity arranged sequentially from the inside to the outside, the water inlet is opened in the water pushing cavity, and the water pushing cavity is also provided with a water pushing component; a water storage hole is opened on the side wall of the water storage cavity; the water pushing component pushes the water sample into the water storage hole and can seal the water storage hole.

[0010] Preferably, the water-pushing component includes a linear drive component disposed in the dispensing tray, the moving end of the linear drive component being located in the water-pushing cavity, and having a plug, a connector, and a push plate arranged sequentially from the inside to the outside, with the plug and the connector being magnetically connected.

[0011] Preferably, the rotary drive includes a motor and a bushing coaxially connected to the output shaft of the motor, the bushing being connected to the dispensing tray.

[0012] Preferably, the top of the dispensing tray is provided with a cover plate, and the cover plate has multiple vent holes, each of which corresponds to one of the receiving cavities.

[0013] This application also provides a method for using the aforementioned dispensing water sample collection device, including the following steps:

[0014] The rotary drive is activated to drive the dispensing tray to rotate to a first set angle, so that the water inlet of the first receiving cavity is connected to the conveying component;

[0015] Activate the lifting drive unit to move the sampling chamber to the required height;

[0016] After the water sample enters the receiving cavity through the sampling chamber, the conveying component, and the water inlet, the dispensing plate is driven to rotate to a second set angle, so that the water inlet of the second receiving cavity is connected to the conveying component.

[0017] The advantages of this invention are as follows: Compared with the prior art, this invention divides the dispensing tray, making each receiving cavity independent and unconnected, thus enabling the storage of multiple water samples; the rotatable dispensing tray, combined with a support part with through holes, allows for storage in only one receiving cavity at a time, while the remaining cavities containing water samples remain sealed to prevent leakage; simultaneously, a lifting drive is provided to facilitate adjustment of the sampling unit's height, allowing for the collection of water samples at different heights. This invention, on the one hand, can simultaneously store multiple different water samples, and on the other hand, can perform water sample collection operations at different heights, meeting the needs of sampling different types of water bodies.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0068] Furthermore, in the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0069] Figure 3 The image shown is a cross-sectional view of the dispensing water sample collection device of the present invention. In the following description, it will be referred to as... Figure 3 The attached diagram serves as a reference for direction. Figure 3 In the view, the direction upward along the paper is called the upward direction, and the direction downward along the paper is called the downward direction. In the dispensing tray 41, the side closer to the center of the dispensing tray 41 is called the inner side, and the side farther away from the center of the dispensing tray 41 is called the outer side.

[0070] like Figure 1 As shown, this invention provides a dispensing water sample collection device, including a sampling unit 20, a lifting drive unit 30, and a dispensing unit 40. The sampling unit 20 is used to draw in water samples and includes a sampling chamber 21 and a conveying component 23 that are interconnected. The moving end of the lifting drive unit 30 is connected to the sampling unit 20 and is used to drive the sampling unit 20 to move up and down, facilitating the collection of water samples at different heights. Figure 3 and Figure 8As shown, the dispensing unit 40 is positioned above the lifting drive unit 30 and includes a dispensing tray 41 and a rotary drive member 42. The rotary drive member 42 is connected to the fixed end of the lifting drive unit 30 and is used to drive the dispensing tray 41 to rotate. The dispensing tray 41 has multiple independent and non-communicating receiving cavities 46 distributed along its circumference. Each receiving cavity 46 has a water inlet hole 44 for communicating with the conveyor 23, which stores the water sample after it enters. When the water sample in one receiving cavity 46 is full, the rotary drive member 42 drives the dispensing tray 41 to rotate, and the sampling unit 20 sucks the water sample into the next receiving cavity 46 through the conveyor 23 and the water inlet hole 44, thereby dispensing the water sample sucked by the sampling unit 20.

[0071] like Figure 1-3 As shown, the sampling chamber 21 has a hollow structure with a sealed top and an open bottom. An annular groove 211 is provided at the upper end of the sampling chamber 21, and an annular protrusion 31 is provided at the moving end of the lifting drive unit 30. The annular protrusion 31 is slidably disposed within the annular groove 211, allowing for a rotatable connection between the moving end of the lifting drive unit 30 and the sampling chamber 21, facilitating the rotation of the sampling chamber 21 in the horizontal plane, rotating with the water flow. A trumpet-shaped enclosure 22 is provided at the lower end of the sampling chamber 21, which helps to expand the range of water sample collection and improve the efficiency of water sample collection. An opening is provided on the side wall of the sampling chamber 21, which connects to the conveying component 23, through which the collected water sample enters the conveying component 23.

[0072] like Figure 1 , 3 As shown in Figure 6, the conveying component 23 includes a connecting pipe 231, a bellows pipe 232, a one-way valve 233, and a water pump 234 connected in sequence. The connecting pipe 231 is connected to the opening of the sampling chamber 21. The lower end of the bellows pipe 232 is connected to the connecting pipe 231, and the upper end is connected to the one-way valve 233. The one-way valve 233 is connected to the water pump 234. The bellows pipe 232 is expandable and can accommodate the vertical movement of the sampling chamber 21. The suction provided by the water pump 234 helps overcome the gravity of the water sample, conveying the water sample from bottom to top. At the same time, the one-way valve 233 restricts the flow direction of the water sample to only upward flow, preventing backflow of the water sample when the water pump 234 stops working. As an alternative, the water pump 234 can also be located in the middle section of the bellows pipe 232, between the bellows pipe 232 and the one-way valve 233, achieving the same technical effect.

[0073] The lifting drive unit 30 is specifically an electric push rod. Those skilled in the art can also choose other mechanical devices such as hydraulic cylinders or pneumatic cylinders that can also achieve the lifting function.

[0074] like Figure 3 and Figure 8As shown, the receiving cavity 46 in the dispensing tray 41 includes a water storage cavity 462 and a water pushing cavity 461 arranged sequentially from the inside to the outside. The water inlet 44 is opened in the water pushing cavity 461, and the water pushing cavity 461 is also provided with a water pushing component 43. A water storage hole 4111 is opened on the side wall of the water storage cavity 462. The water pushing component 43 pushes the water sample into the water storage hole 4111 and can seal the water storage hole 4111, so that the water sample is sealed and stored in the water storage cavity 462.

[0075] Specifically, a first partition 411, multiple second partitions 412, and a third partition 413 are provided within the dispensing tray 41. The first partition 411 and the third partition 413 are both annular and concentrically arranged with the dispensing tray 41, with the first partition 411 located inside the third partition 413. The second partitions 412 extend radially along the dispensing tray 41, connecting the center of the dispensing tray 41, the first partition 411, and the third partition 413 sequentially from the inside out. The multiple second partitions 412 are evenly spaced along the circumference of the dispensing tray 41. The cavity between two adjacent second partitions 412 and the first partition 411 is a water storage cavity 462, and the cavity between two adjacent second partitions 412, the first partition 411, and the third partition 413 is a water pushing cavity 461. A water inlet 44 is located at the bottom of the water pushing cavity 461.

[0076] The water-pushing component 43 includes multiple linear drive components 431 disposed in the dispensing tray 41, each linear drive component 431 corresponding to a water-pushing chamber 461. The moving end of the linear drive component 431 is located in the water-pushing chamber 461, and is provided with a plug 434, a connector 433, and a push plate 432 in sequence from the inside to the outside. The plug 434 and the connector 433 are magnetically connected. Specifically, the linear drive component 431 is an electric push rod. Those skilled in the art can also use other mechanical devices such as hydraulic cylinders or pneumatic cylinders that can drive the plug 434, connector 433, and push plate 432 to make linear displacement.

[0077] After the water sample enters the pushing chamber 461 via the conveyor 23 and the inlet 44, the moving end of the linear drive 431 moves inward, pushing the water sample through the storage hole 4111 into the storage chamber 462. Then, the moving end of the linear drive 431 continues to move inward, inserting the plug 434 into the storage hole 4111. At this point, the moving end of the linear drive 431 moves outward, and due to the friction between the plug 434 and the storage hole 4111, the plug 434 separates from the connector 433, sealing the storage chamber 462 and completing one water sample dispensing operation. Preferably, the plug 434 can be made of materials such as wood or rubber, and its shape and size match the storage hole 4111.

[0078] After completing one water sample dispensing, the rotary drive 42 drives the dispensing disk 41 to rotate, connecting the water inlet 44 of the next water pushing chamber 461 with the conveyor 23, and starting a new dispensing cycle. The rotary drive 42 specifically includes a motor 421 and a bushing 422 coaxially connected to the output shaft of the motor 421. The bushing 422 is keyed to the dispensing disk 41, and the motor 421 is connected to the fixed end of the lifting drive unit 30.

[0079] Those skilled in the art can directly connect the fixed end of the lifting drive unit 30 to the dispensing unit 40, or, as in a specific embodiment of the present invention, such as... Figure 1 and Figure 3 As shown, a disc-shaped support 10 is provided between the fixed end of the lifting drive unit 30 and the sub-assembly unit 40. The support 10 serves as a support platform to facilitate the connection and support of the lifting drive unit 30 and the sub-assembly unit 40. The fixed end of the motor 421 is located inside the support 10.

[0080] like Figure 3-5 and Figure 7 As shown, the support part 10 has a vertical through hole 11, which connects the water inlet hole 44 and the conveying component 23. The lower end of the through hole 11 is connected to the water pump 234, and the upper end is provided with a countersunk hole 12. The diameter of the countersunk hole 12 is larger than that of the through hole 11. A first waterproof gasket 50 and a first magnetic gasket 60 are arranged sequentially from top to bottom in the countersunk hole 12. A second magnetic gasket 80 and a second waterproof gasket 70 are arranged sequentially from top to bottom in the water inlet hole 44. The first waterproof gasket 50 and the second waterproof gasket 70 are adjacent to each other. The first magnetic gasket 60 and the second magnetic gasket 80 attract each other when aligned, so that the first waterproof gasket 50 and the second waterproof gasket 70 fit tightly together, which plays a sealing role and prevents the water sample from leaking out from between the through hole 11 and the dispensing tray 41.

[0081] There is only one through hole 11. The water inlet 44 and the conveying component 23 can communicate with each other and the water sample can be conveyed into the water storage chamber 462 only when the through hole 11 is aligned with the water inlet 44. When the dispensing tray 41 is rotated to a position where the other through holes 11 are not aligned with the water inlet 44, the water sample cannot be conveyed into the water storage chamber 462.

[0082] Combination Figure 1-8 As can be seen, the working principle of a specific embodiment of the present invention is as follows:

[0083] First, the motor 421 is started, driving the dispensing tray 41 to rotate to the first set angle, so that the water inlet hole 44 on the dispensing tray 41 is connected to the through hole 11. At this time, the first magnetic suction washer 60 and the second magnetic suction washer 80 are aligned with each other, and the first waterproof washer 50 and the second waterproof washer 70 are tightly fitted, so that the support part 10 and the dispensing part 40 have a good watertight effect. Then, the lifting drive part 30 is started to move the sampling chamber 21 up and down to the required sampling position, and the water pump 234 is started to collect water samples. The water samples pass through the connecting pipe 231, the corrugated pipe 232, the one-way valve 233, the water pump 234, the through hole 11, and the water inlet hole 44 in sequence into the water pushing chamber 461. The water samples enter the water storage chamber 462 under the pushing action of the push plate 432 driven by the linear drive part 431. Finally, the water storage chamber 462 is sealed by the plug 434. The dispensing tray 41 is rotated to the second set angle, so that another water inlet hole 44 on the dispensing tray 41 is connected to the through hole 11, and the water sample is stored again. At the same time, the height position of the sampling chamber 21 can be adjusted as needed to collect water samples at different heights.

[0084] This application also provides a method for using the aforementioned dispensing water sample collection device, including the following steps:

[0085] Start the rotary drive 42 to drive the dispensing tray 41 to rotate to the first set angle, so that the water inlet 44 of the first receiving cavity 46 is connected to the conveyor 23.

[0086] Start the lifting drive unit 30 to move the sampling chamber 21 to the required height;

[0087] After the water sample enters the receiving cavity 46 through the sampling chamber 21, the conveyor 23, and the water inlet 44, the dispensing plate 41 is driven to rotate to the second set angle, so that the water inlet 44 of the second receiving cavity 46 is connected to the conveyor 23.

[0088] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
