Description

Technical Field

[0001] This utility model belongs to the field of sediment sampling technology, specifically relating to an automatic runoff sediment sampler. Background Technology

[0002] Currently, soil and water loss monitoring is mainly carried out through sediment sampling. Specifically, within the monitoring area, target runoff plots are selected, and water flow from the runoff plots is sampled using sampling equipment. The sediment content in the sampled water flow is then analyzed to obtain soil and water loss data.

[0003] However, due to the high sediment content in the water flow, existing sampling equipment cannot adjust the sampling components according to the amount of sediment in the water flow, resulting in a large amount of sediment clogging the sampling channel, making sampling difficult and unable to obtain accurate data. Secondly, most existing sampling equipment uses peristaltic pumps for water intake, which easily leads to damage to the peristaltic pumps, requiring frequent maintenance, causing a sharp increase in sampling costs, which is not conducive to the normal operation of sampling. Summary of the Invention

[0004] The purpose of this utility model is to provide an automatic runoff sediment sampler. On the one hand, it solves the technical defect of existing sampling equipment that cannot adjust the sampling components according to the amount of sediment in the water flow, resulting in a large amount of sediment clogging the sampling channel, making sampling difficult and unable to obtain accurate data. On the other hand, it solves the technical defect of existing sampling equipment that mostly uses peristaltic pumps for water intake, which causes a sharp increase in sampling costs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] The control device is electrically connected to the sampling component, the flow monitoring component, and the rotating component;

[0012] When sampling runoff sediment, the flow monitoring device is used to measure the flow rate of runoff sediment so that the control device can adjust the state of the sampling component.

[0013] Furthermore, the sampling assembly includes a housing, which is disposed on the top of one side of the support device, and the flow monitoring device is disposed on the top of the housing; the housing is provided with a tipping bucket and a damper, the tipping bucket is rotatably connected to the housing through a tipping bucket bearing, and the damper is disposed above the tipping bucket;

[0014] The outer side of the box is provided with a water inlet pipe. One end of the water inlet pipe is connected to the inside of the box, and the other end is connected to a push rod water inlet pipe. The end of the push rod water inlet pipe is connected to a push rod fixing frame. An adjustment component and a water pipe are installed on the push rod fixing frame. One end of the water pipe is rotatably connected to the push rod fixing frame, and the other end is rotatably connected to the adjustment component. The water pipe cooperates with the sampling component.

[0015] Furthermore, the flow monitoring device is a reed switch.

[0016] Furthermore, the water pipe includes a sampling pipe and a drain pipe, and the push rod fixing frame includes a fixing frame body, a flow guiding chamber and an adjustment chamber. The flow guiding chamber is disposed on the fixing frame body, and the adjustment chamber is rotatably connected to the flow guiding chamber.

[0017] The end of the push rod inlet pipe is mounted on the fixed frame body and extends into the flow guide chamber. One end of the sampling pipe and the drain pipe are both connected to the regulating chamber, and the other ends of the sampling pipe and the drain pipe are far apart from each other.

[0018] The adjustment assembly includes an electric push rod and a rotating shaft. The rotating shaft is located outside the drain pipe, and the end of the electric push rod engages with the rotating shaft.

[0019] Furthermore, both the electric push rod and the sampling tube are located above the drain pipe.

[0020] Furthermore, the sampling component includes a rotary disk, the rotating component is disposed at the bottom of the rotary disk, a plurality of weighing sensors are provided on the outer circumference of the rotary disk, a sampling bottle support plate is provided on each of the plurality of weighing sensors, and a sampling bottle is installed in the sampling bottle support plate.

[0021] Furthermore, a sampling bottle fixing plate is installed on the top of the rotating disk. The sampling bottle fixing plate is gear-shaped, and the edge of the sampling bottle fixing plate mates with the sampling bottle.

[0022] Furthermore, the rotating assembly includes a base plate, which is detachably connected to the rotary disk. A motor is mounted on the bottom of the base plate, and the drive end of the motor is connected to the rotary disk.

[0023] Furthermore, a three-color alarm light is provided on the outside of the sampling bottle.

[0024] Furthermore, the support device includes a cabinet, and the sampling component, rotating component and control device are all disposed in the cabinet. The bottom of the cabinet is provided with casters around its perimeter.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. When using this sampler to sample water flow in a runoff area, the sampling component is aligned with the direction of water flow, allowing the water to flow smoothly into the sampling component. During the process of water entering the sampling component, the flow monitoring device inside the sampling component can count the amount of runoff, and the control device adjusts the state of the sampling component according to the amount of runoff. This solves the technical defects of excessive water flow and high sediment content causing blockage of the sampling channel and affecting the sampling operation. Secondly, this sampling mechanism does not require the use of a peristaltic pump during the sampling process, reducing sampling costs.

[0027] 2. A flow monitoring device is installed on the top of the tank to monitor the water flow information in real time and accurately, providing reliable data support for sampling. The tipping bucket is rotatably connected to the tank via a tipping bucket bearing. Combined with a damper, this ensures the stability and reliability of the tipping bucket when receiving water flow. The damper effectively slows down the tipping speed, preventing excessively rapid tipping or instability caused by water flow impact, thereby improving the accuracy and continuity of sampling.

[0028] 3. As a magnetic switch, the reed switch has extremely high sensitivity and accuracy. In flow monitoring, when water flows through, it can cause a change in the magnetic field, which in turn triggers the opening and closing action of the reed switch. This direct physical action mechanism makes flow detection more accurate and can capture minute changes in flow.

[0029] 4. By dividing the water pipe into a sampling pipe and a drainage pipe, when the water flow is large, the sampling pipe and the drainage pipe can be flexibly switched during the sampling process through the function of the adjustment component, so as to ensure that a certain amount of sediment can be sampled.

[0030] 5. The electric push rod and sampling tube are located above the drain pipe, which allows the adjustment component to easily switch between the sampling tube and the drain pipe.

[0031] 6. By driving the rotary disk to rotate through a rotating component, multiple sampling bottles can be automatically rotated for sampling, improving sampling efficiency and reducing the need for manual operation and error rate. Each sampling bottle is equipped with a weighing sensor underneath, which can monitor the weight change of the sampling bottle in real time and accurately, ensuring the accuracy and reliability of sampling.

[0032] 7. The gear-shaped design of the sampling bottle fixing plate tightly engages with or secures the sampling bottles, preventing them from shaking or falling off during the rotation of the rotating disc. This ensures a smooth sampling process and avoids errors or accidents caused by changes in the position of the sampling bottles. The engagement of the gear-shaped edges with the sampling bottles makes the position of each bottle on the rotating disc more clearly defined and fixed, helping operators to quickly and accurately locate and replace sampling bottles, thus improving operational efficiency.

[0033] 8. The motor is directly mounted on the bottom of the base plate and connected to the rotary disk through the drive end, ensuring high efficiency of power transmission and providing stable power support for the sampling process.

[0034] 9. The three-color alarm light can reflect the current status of the sampling bottle in an instant and intuitive way, such as empty bottle, full bottle, abnormality or malfunction. Operators can quickly understand the status of the sampling bottle by observing the color change of the alarm light, and thus take appropriate measures in a timely manner.

[0047] Currently, soil and water loss monitoring is mainly carried out through sediment sampling. Specifically, within the monitoring area, target runoff plots are selected, and water flow from the runoff plots is sampled using sampling equipment. The sediment content in the sampled water flow is then analyzed to obtain soil and water loss data.

[0048] However, due to the high sediment content in the water flow, existing sampling equipment cannot adjust the sampling components according to the amount of sediment in the water flow, resulting in a large amount of sediment clogging the sampling channel, making sampling difficult and unable to obtain accurate data. Secondly, most existing sampling equipment uses peristaltic pumps for water intake, which easily leads to damage to the peristaltic pumps, requiring frequent maintenance, causing a sharp increase in sampling costs, which is not conducive to the normal operation of sampling.

[0049] To address the aforementioned technical deficiencies, the inventors have provided an automatic runoff sediment sampler.

[0050] The present invention will now be described in further detail with reference to the accompanying drawings:

[0051] like Figures 1-4As shown, this utility model embodiment provides an automatic runoff sediment sampler, including: a support device; a sampling component disposed on top of the support device, the sampling component having a flow monitoring element inside; a sampling assembly disposed inside the support device and located below the sampling component, cooperating with the sampling component; a rotating assembly, one end of which is connected to the support device and the other end of which is connected to the bottom of the sampling assembly, the rotating assembly being used to drive the sampling assembly to rotate; and a control device electrically connected to the sampling component, the flow monitoring element, and the rotating assembly, the flow monitoring element being used to measure the flow rate of runoff sediment so that the control device can adjust the state of the sampling component. The control device has a sampler operation interface, which includes a parameter page for the entire mechanism's operation, a sampling duration control interface, a sampling state switching interface, and a sampling status interface, the sampling status interface being used to display "out of bottle," "empty bottle," and "full bottle" information. Electrical box 3 is also located on top of the support device and opposite the sampling component. When sampling runoff sediment, the sampling component is aligned with the direction of water flow within the runoff area, allowing the water to flow smoothly into the sampling component. During the water flow into the sampling component, the flow monitoring device inside the sampling component can count the amount of runoff. The control device then adjusts the state of the sampling component according to the amount of runoff, solving the technical defects of excessive water flow and high sediment content causing blockage of the sampling channel and affecting the sampling operation. Secondly, this sampling mechanism does not require the use of a peristaltic pump during the sampling process, reducing sampling costs.

[0052] like Figure 1 and Figure 2 As shown, the sampling component, namely the tipping bucket flow meter 1, includes a housing 19. The housing 19 is located on the top of one side of the support device. The housing 19 is used to allow water flow and sediment to enter. The bottom of the housing 19 is the inner wall of the cone, which has been polished or coated (waxed or coated with a high-gloss paint) to reduce the deposits on the inner wall surface after the runoff is discharged (mainly sediment, which will seriously affect the accuracy of subsequent measurements).

[0053] The flow monitoring device is located on the top of the housing 19 and can detect the flow rate in real time. The housing 19 is equipped with a tipping bucket 22, a damper 23 and a baffle plate 21. The outer side of the housing 19 is equipped with a latch 26. The tipping bucket 22 is rotatably connected to the housing 19 through a tipping bucket bearing 24. The damper 23 is located above the tipping bucket 22. The tipping bucket 22 is rotatably connected to the housing 19 through the tipping bucket bearing 24. With the use of the damper 23, the stability and reliability of the tipping bucket 22 when receiving water flow are ensured. The damper 23 can effectively slow down the tipping speed of the tipping bucket 22 and prevent excessively fast tipping or instability caused by water flow impact, thereby improving the accuracy and continuity of sampling. A water inlet pipe 20 is provided on the outside of the housing 19. One end of the water inlet pipe 20 communicates with the inside of the housing 19, and the other end is connected to a push rod water inlet pipe 8. The end of the push rod water inlet pipe 8 is connected to a push rod fixing bracket 10. An adjusting component 9 and a water pipe 11 are mounted on the push rod fixing bracket 10. One end of the water pipe 11 is rotatably connected to the push rod fixing bracket 10, and the other end is rotatably connected to the adjusting component 9. The water pipe 11 cooperates with the sampling component. When the water flow is too large, the control device receives a feedback signal and controls the adjusting component 9 to start operation. The adjusting component 9 then adjusts the water pipe 11 according to the operation command issued by the control device, thereby causing the water pipe 11 to discharge water. Figure 4 As shown, the flow monitoring device is preferably a reed switch 25. As a magnetic switch, the reed switch 25 has extremely high sensitivity and accuracy. In flow monitoring, when water flows through, it can cause a change in the magnetic field, which in turn triggers the opening and closing action of the reed switch 25. This direct physical action mechanism makes the flow detection more accurate and can capture minute changes in flow.

[0054] like Figure 2As shown, the water pipe 11 includes a sampling pipe 1101 and a drain pipe 1102. The push rod fixing frame 10 includes a fixing frame body, a flow guiding chamber 1001, and an adjustment chamber 1002. The flow guiding chamber 1001 is disposed on the fixing frame body, and the adjustment chamber 1002 is rotatably connected to the flow guiding chamber 1001. The end of the push rod inlet pipe 8 is installed on the fixing frame body and extends into the flow guiding chamber 1001. One end of the sampling pipe 1101 and the drain pipe 1102 are both connected to the adjustment chamber 1002, and the other ends of the sampling pipe 1101 and the drain pipe 1102 are far apart from each other. The adjustment assembly 9 includes an electric push rod 901 and a rotating shaft 902. The rotating shaft 902 is disposed outside the drain pipe 1102, and the end of the electric push rod 901 cooperates with the rotating shaft 902. By dividing the water pipe 11 into a sampling pipe 1101 and a drainage pipe 1102, the drainage pipe 1102 is connected to the water pipe 4 to discharge the water flow. When the water flow is large, the sampling pipe 1101 and the drainage pipe 1102 can be flexibly switched during the sampling process through the action of the adjustment component 9 to ensure that a certain amount of sediment can be sampled. Secondly, the electric push rod 901 and the sampling pipe 1101 are set above the drainage pipe 1102, so that the adjustment component 9 can smoothly switch the sampling pipe 1101 and the drainage pipe 1102. After the runoff water sample flows into the sampling bottle 6 through the sampling pipe 1101, and the sampling bottle 6 completes the sampling, the control device controls the electric push rod 901 to switch to the operation state of the drainage pipe 1102.

[0055] like Figure 3 As shown, the sampling assembly includes a rotating disk 18. A rotating component is located at the bottom of the rotating disk 18. Multiple weighing sensors 14 are arranged on the outer circumference of the rotating disk 18. Each weighing sensor 14 is equipped with a sampling bottle support plate 12. A sampling bottle 6 is installed inside the sampling bottle support plate 12. By driving the rotating disk 18 to rotate through the rotating component, multiple sampling bottles 6 can be automatically rotated for sampling. The sampling bottle 6 that has been sampled is weighed by the weighing sensor 14 and the data is recorded, which improves sampling efficiency and reduces the need for manual operation and error rate. Each sampling bottle 6 is equipped with a weighing sensor 14 below it, which can monitor the weight change of the sampling bottle 6 in real time and accurately, ensuring the accuracy and reliability of sampling. A sampling bottle fixing plate 13 is installed on the top of the rotating disk 18. The sampling bottle fixing plate 13 is gear-shaped, and the edge of the sampling bottle fixing plate 13 mates with the sampling bottle 6. The gear-shaped design of the sampling bottle fixing plate 13 can tightly engage or fix the sampling bottle 6, preventing the sampling bottle 6 from shaking or falling off during the rotation of the rotary disc 18, ensuring the smooth progress of the sampling process and avoiding errors or accidents caused by changes in the position of the sampling bottle 6. Secondly, the cooperation between the gear-shaped edge and the sampling bottle 6 makes the position of each sampling bottle 6 on the rotary disc 18 more clear and fixed, helping operators to quickly and accurately locate and replace the sampling bottle 6, thus improving operational efficiency. Figure 3As shown, the rotating assembly includes a base plate 15, which is detachably connected to a rotating disk 18. A motor 17 is mounted on the bottom of the base plate 15 via fixing bolts 16, and the drive end of the motor 17 is connected to the rotating disk 18. In this embodiment, a three-color alarm light is provided on the outside of the sampling bottle 6. The three-color alarm light can reflect the current status of the sampling bottle 6 immediately and intuitively, such as empty bottle, full bottle, abnormality, or malfunction. The operator can quickly understand the status of the sampling bottle 6 by observing the color change of the alarm light, and thus take appropriate measures in a timely manner. Finally, in this embodiment, the support device includes a cabinet 2. The sampling assembly, rotating assembly, and control device are all housed inside the cabinet 2. Casters 5 are provided around the bottom of the cabinet 2. An emergency stop device is installed at the cabinet door. When the operator opens the cabinet door, the rotating platform 7 stops rotating. In order to retrieve the sampling bottle 6 in an emergency, an emergency stop foot switch is also provided. The sampler's operation can be stopped immediately by stepping on the foot switch, and the sampling bottle 6 can be retrieved.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit its protection scope. Although the utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that after reading this utility model, they can still make various changes, modifications or equivalent substitutions to the specific implementation of the invention, but these changes, modifications or equivalent substitutions are all within the protection scope of the pending claims of the invention.
