Description

Technical Field

[0001] This utility model relates to the field of rainwater harvesting technology, specifically providing an adjustable rainwater sampling and storage device. Background Technology

[0002] Existing rainwater sampling devices generally suffer from problems such as uncontrollable sampling volume, insufficient structural stability, and inaccurate sampling measurement. Traditional sampling funnels lack graduation markings, making it impossible to intuitively determine the amount of sample taken in a single sampling; the adjustment components are poorly designed, making it difficult to accurately control the rainwater flow rate; the storage containers lack metering scales, resulting in large errors in sample volume recording; and most devices do not have dedicated fixed supports, making them susceptible to tilting or displacement due to external forces, affecting sampling efficiency and sample purity.

[0003] Accordingly, there is a need in the field for a new adjustable rainwater sampling and storage device to solve the above-mentioned technical problems. Summary of the Invention

[0004] The present invention aims to solve the above-mentioned technical problems, namely, to solve the problem of poor stability of existing rainwater sampling and storage devices.

[0005] This utility model provides an adjustable rainwater sampling and storage device, the sampling and storage device comprising: A support frame, wherein the bottom of the support frame is configured as a placement end, and a mounting groove is formed on the placement end; the top of the support frame is configured as a clamping end; A water tank, the bottom of which is inserted into the mounting groove, and a water inlet formed on the top of which are provided. The sampling assembly includes a cup body, a filter screen, a valve, and an infusion tube. The cup body is mounted on the clamping end via a connector. The filter screen is mounted on the top of the cup body. The inlet end of the valve is connected to the bottom of the cup body. The valve is fixedly connected to the support frame. The inlet end of the infusion tube is connected to the outlet end of the valve. The outlet end of the infusion tube corresponds to the water inlet of the water tank.

[0006] Based on the above structural design, by setting the support frame at the placement end and the clamping end, the water tank and the sampling component are stably fixed, preventing the components from loosening or shifting. Inserting the installation groove into the bottom of the water tank can enhance placement stability and prevent the water tank from tipping over during sampling. This solves the problem of poor stability caused by the lack of a dedicated fixing structure in traditional devices. At the same time, the filter screen in the sampling component can filter impurities in the rainwater, making up for the defect of samples containing impurities due to the lack of a filtration structure in traditional devices. The valve can control the rainwater flow rate, realizing flexible adjustment of the sampling volume and improving the situation of uncontrollable sampling volume in existing devices.

[0007] In the preferred embodiment of the above-mentioned adjustable rainwater sampling and storage device, the support frame includes a column, a base, a first support rod, and a second support rod, with the placement end disposed on the base; the column is fixedly installed on the upper end of the base; the first end of the first support rod is connected to the cup body via a connector, and the second end of the first support rod is fixedly connected to the column; the first end of the second support rod is connected to the side of the valve via a thread, and the second end of the second support rod is fixedly connected to the column.

[0008] Based on the above structural design, the support frame uses a split design of columns, base, first support rod, and second support rod to separately fix the cup and valve, disperse the stress points, and enhance the overall structural strength of the device. The first support rod is specifically for fixing the cup, and the second support rod is specifically for fixing the valve, avoiding excessive stress on a single support point that could cause component deformation or detachment. The base expands the support area, further improving the stability of the device and ensuring that it remains structurally stable even in windy or rainy environments, thus extending the device's service life.

[0009] In the preferred embodiment of the above-mentioned adjustable rainwater sampling and storage device, the connecting member is configured as a clamp structure.

[0010] Based on the above structural design, the connector adopts a clamp structure, which can quickly install and disassemble the cup body and the first support rod. The operation is convenient and does not require professional tools. The clamp can be adjusted to fit cup bodies of different sizes, improving the versatility of the device for different sampling needs. At the same time, the clamp fixing method is tight and reliable, which can effectively prevent the cup body from shaking due to vibration or wind during the sampling process, ensuring sampling stability.

[0011] In the preferred embodiment of the above-mentioned adjustable rainwater sampling and storage device, the column is configured as an upper column and a lower column, and the upper column and the lower column are connected by a height adjustment structure.

[0012] Based on the above structural design, the support column consists of an upper column and a lower column connected by a height adjustment mechanism, allowing the overall height of the device to be flexibly adjusted according to the actual sampling scenario. For example, the height can be lowered in higher terrain and raised in areas with dense vegetation, ensuring that the cup is in the optimal position for rainwater collection, improving sampling flexibility and environmental adaptability, and solving the problem of limited applicability of traditional fixed-height devices.

[0013] In the preferred embodiment of the above-mentioned adjustable rainwater sampling and storage device, the height adjustment structure is configured as an adjustment bolt, the upper column and the lower column are sleeved and connected, the upper column and the lower column are provided with multiple threaded grooves along the same direction and at equal intervals, and the adjustment bolt is set in the threaded groove where the upper column and the lower column intersect.

[0014] Based on the above structural design, the height adjustment structure uses adjusting bolts in conjunction with multiple sets of threaded grooves. By selecting bolts with threaded grooves of different heights, precise graded adjustment of the column height can be achieved, and the adjustment accuracy is stable and controllable. The rigid connection between the bolts and the threaded grooves has high strength, which can firmly lock the adjusted height and prevent height deviation caused by external forces during use, ensuring the stability of the sampling position. At the same time, the structure is simple.

[0015] In the preferred embodiment of the above-mentioned adjustable rainwater sampling and storage device, an anti-slip pad is provided at the bottom of the base.

[0016] Based on the above structural design, an anti-slip pad is installed at the bottom of the base, which can increase the friction between the base and the placement surface, effectively preventing the device from sliding or shifting under wet ground, slight vibration or wind. Especially when sampling in rainy weather, it can prevent the device from tipping over due to slippery ground, further improving the stability and safety of the device placement and ensuring the continuous and reliable sampling process.

[0017] In the preferred embodiment of the above-mentioned adjustable rainwater sampling and storage device, a transparent area is formed on the side wall of the water tank, and the transparent area is provided with scale lines.

[0018] Based on the above structural design, the transparent area on the side wall of the water tank, along with the scale lines, allows for direct observation of the amount of rainwater stored in the tank. The sampling progress can be monitored in real time without opening the tank, reducing interference with the sample during the sampling process. The scale lines can accurately measure the amount of rainwater, making it easier for operators to record sampling data, improving the accuracy of sampling statistics, and providing reliable basic data support for subsequent water quality analysis.

[0019] In the preferred embodiment of the above-mentioned adjustable rainwater sampling and storage device, the valve is configured as a manual ball valve, and the manual ball valve switch is provided with a rotation angle scale.

[0020] Based on the above structural design, the valve adopts a manual ball valve structure, which is easy and flexible to operate, and has a rapid opening and closing response, allowing for quick control of rainwater flow. The rotation angle scale at the switch can intuitively reflect the degree of valve opening, making it easy for operators to accurately adjust the rainwater flow according to their needs, achieving controllability of sampling speed, improving the accuracy of sampling volume control, and meeting the needs of different sampling volumes.

[0021] In the preferred embodiment of the above-mentioned adjustable rainwater sampling and storage device, the cup body is configured as a sampling funnel, and the inner wall of the sampling funnel is provided with capacity markings along the height direction.

[0022] Based on the above structural design, the cup body is set as a sampling funnel. Its open structure can increase the rainwater collection area and improve the sampling efficiency per unit time, which is especially suitable for light rain scenarios. The capacity scale along the height direction of the inner wall can intuitively display the temporary volume of rainwater in the funnel, which makes it easy for operators to judge the sampling volume in real time. Combined with valve adjustment, the volume of a single sampling can be precisely controlled, reducing sampling errors.

[0023] In the preferred embodiment of the above-mentioned adjustable rainwater sampling and storage device, the bottom of the sampling funnel is connected to the valve via a threaded structure.

[0024] Based on the above structural design, the bottom of the sampling funnel is connected to the valve via a threaded connection. The threaded connection provides good sealing, effectively preventing rainwater leakage at the connection point and ensuring accurate sampling measurement. At the same time, the threaded connection is easy to disassemble, facilitating regular cleaning, maintenance, or replacement of the funnel and valve. This avoids contamination of subsequent samples by residual impurities in the components, extends the service life of the device, and improves maintenance convenience. Attached Figure Description

These are merely for ease of description and do not indicate or imply that the structure must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] First refer to Figure 1 ,like Figure 1 As shown, this utility model provides an adjustable rainwater sampling and storage device, which includes: The support frame has a placement end at the bottom with a mounting groove formed thereon, and a clamping end at the top. Water tank 2 is inserted into an installation groove at its bottom, and has a water inlet at its top. It should be noted that this invention does not impose any limitations on the specific structure of water tank 2; those skilled in the art can design it according to their needs. For example, water tank 2 can be a cylindrical water tank, or it can be a cuboid water tank, as long as the volume inside is sufficient for rainwater collection. In this preferred embodiment, a transparent area 7 is formed on the side wall of water tank 2, and scale lines are provided in the transparent area 7. The transparent area 7, in conjunction with the scale lines, allows for direct observation of the amount of rainwater stored in water tank 2. The sampling progress can be monitored in real time without opening water tank 2, reducing interference with the sample during sampling. The scale lines accurately measure the amount of rainwater, facilitating the recording of sampling data by operators, improving the accuracy of sampling statistics, and providing reliable basic data support for subsequent water quality analysis.

[0031] The sampling assembly includes a cup body 1, a filter screen 4, a valve 5, and an infusion tube 6. The cup body 1 is mounted on the clamping end via a connector; the filter screen 4 is mounted on the top of the cup body 1; the inlet end of the valve 5 is connected to the bottom of the cup body 1; the valve 5 is fixedly connected to a support frame; the inlet end of the infusion tube 6 is connected to the outlet end of the valve 5; and the outlet end of the infusion tube 6 corresponds to the inlet of the water tank 2. It should be noted that this invention does not impose any limitations on the structure of the cup body 1. Those skilled in the art can design it according to their needs. For example, the cup body 1 can be a plastic sampling cup, or it can be a glass sampling cup, as long as the cup body 1 is sufficient for rainwater sampling. In this preferred embodiment, the cup body 1 is configured as a sampling funnel, and the inner wall of the sampling funnel has capacity markings along the height direction. The cup body 1 is designed as a sampling funnel. Its open structure increases the rainwater collection area and improves the sampling efficiency per unit time, making it particularly suitable for light rainfall scenarios. The volume scale along the height of the inner wall clearly displays the temporary rainwater volume within the funnel, allowing operators to easily judge the sampling volume in real time. Combined with valve 5, the volume of a single sample can be precisely controlled, reducing sampling errors. The bottom of the sampling funnel is connected to valve 5 via a threaded connection. This threaded connection provides a good seal, effectively preventing rainwater leakage at the connection point and ensuring accurate sampling measurement. Simultaneously, the threaded connection facilitates disassembly, allowing for regular cleaning, maintenance, or replacement of the funnel and valve 5, preventing residual impurities from contaminating subsequent samples, extending the device's lifespan, and improving maintenance convenience.

[0032] By setting the support frame at the placement end and the clamping end, the water tank 2 and the sampling component are stably fixed, avoiding loosening or displacement of the components. The installation groove inserted into the bottom of the water tank 2 can enhance the placement stability and prevent the water tank 2 from tipping over during sampling. This solves the problem of poor stability caused by the lack of a dedicated fixing structure in traditional devices. At the same time, the filter screen 4 in the sampling component can filter impurities in the rainwater, making up for the defect of impurities in the sample caused by the lack of a filtration structure in traditional devices. The valve 5 can control the rainwater flow rate, realize flexible adjustment of the sampling volume, and improve the situation of uncontrollable sampling volume in existing devices.

[0033] Furthermore, the support frame includes a column, a base 8, a first support rod 12, and a second support rod 10, with the placement end located on the base 8. The column is fixedly installed on the upper end of the base 8. The first end of the first support rod 12 is connected to the cup body 1 via a connector, and the second end of the first support rod 12 is fixedly connected to the column. The first end of the second support rod 10 is connected to the side of the valve 5 via a thread, and the second end of the second support rod 10 is fixedly connected to the column. Through the separate design of the column, base 8, first support rod 12, and second support rod 10, the support frame achieves separate fixation of the cup body 1 and the valve 5, dispersing the stress points and enhancing the overall structural strength of the device. The first support rod 12 is specifically used to fix the cup body 1, and the second support rod 10 is specifically used to fix the valve 5, avoiding excessive stress on a single support point that could cause component deformation or detachment. The base 8 expands the support area, further improving the placement stability of the device and ensuring that the structure remains stable even in windy and rainy environments, thus extending the service life of the device. It should be noted that this utility model does not impose any restrictions on the specific structure of the column and the base 8. Those skilled in the art can set it according to their needs, as long as the column and the base 8 can provide good support.

[0034] In a preferred embodiment, the connector is configured as a clamp structure 3. The clamp structure 3 allows for quick installation and disassembly of the cup body 1 and the first support rod 12, providing convenient operation without the need for specialized tools. The clamp can be adjusted to fit cup bodies 1 of different sizes, improving the device's versatility for various sampling needs. Simultaneously, the clamp's secure fixing method is tight and reliable, effectively preventing the cup body 1 from shaking due to vibration or wind during sampling, ensuring sampling stability. In this invention, the clamp structure 3 consists of two arc-shaped clamp pieces, a fastening bolt, and a nut. The arc-shaped clamp pieces are made of high-strength stainless steel, possessing good rigidity and corrosion resistance, adapting to the humid environment of outdoor rainwater sampling. The two clamp pieces are connected by a hinge at one end, and the other end has a threaded hole for the fastening bolt to pass through. Tightening the nut tightens the clamp pieces, thereby fixing the cup body 1.

[0035] See below. Figure 2 ,like Figure 2As shown, the support structure consists of an upper support column 11 and a lower support column 9, connected by a height adjustment mechanism. This allows the overall height of the device to be flexibly adjusted according to the actual sampling scenario. For example, the height can be lowered in higher terrain and raised in areas with dense vegetation, ensuring that the cup 1 is in the optimal rainwater collection position. This improves sampling flexibility and environmental adaptability, solving the problem of limited applicability of traditional fixed-height devices. In this preferred embodiment, the height adjustment structure is configured as an adjusting bolt 13. The upper column 11 and the lower column 9 are sleeved and connected. The upper column 11 and the lower column 9 are provided with multiple threaded grooves along the same direction and at equal intervals. The adjusting bolt 13 is set in the threaded groove where the upper column 11 and the lower column 9 intersect. The height adjustment structure uses the adjusting bolt 13 in conjunction with multiple sets of threaded grooves. By selecting threaded grooves of different heights to install bolts, precise graded adjustment of the column height can be achieved, and the adjustment accuracy is stable and controllable. The rigid connection between the bolt and the threaded groove has high strength, which can firmly lock the adjusted height and avoid height deviation caused by external force during use, ensuring the stability of the sampling position. At the same time, the structure is simple.

[0036] Furthermore, the bottom of the base 8 is provided with an anti-slip pad, which increases the friction between the base 8 and the placement surface, effectively preventing the device from sliding or shifting under wet ground, slight vibration or wind. Especially when sampling in rainy weather, it can prevent the device from tipping over due to slippery ground, further improving the stability and safety of the device placement and ensuring the continuous and reliable sampling process.

[0037] Furthermore, valve 5 is configured as a manual ball valve with a rotation angle scale at the switch. Valve 5 is easy and flexible to operate, with a rapid switching response, and can quickly control the flow of rainwater. The rotation angle scale at the switch can intuitively reflect the degree of valve 5 opening, making it easy for operators to accurately adjust the rainwater flow according to their needs, achieving controllability of sampling speed, improving the accuracy of sampling volume control, and meeting the needs of different sampling volumes.

However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
