Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of precipitation collection, in particular to a continuous precipitation intelligent collector and collection method. BACKGROUND

[0002] In the fields of meteorological monitoring, environmental assessment, hydrological research, etc., continuous and accurate collection of precipitation samples is the key basis for obtaining effective data. The traditional precipitation collection method mainly has the following problems: Most devices lack physical isolation mechanisms, and precipitation samples at different times are easily mixed during the collection process, resulting in sample component distortion. For example, in the same isotope analysis test at different times, the residual sample in the previous period may affect the isotope determination in the sample in the next period, directly leading to inaccuracy of isotope tracing. Relying on manual replacement of sampling containers at regular intervals not only consumes a large amount of labor cost, but also often causes problems such as operation delay, inability to work at night or in bad weather, etc., resulting in missing of sampling time period. According to statistics, the effective data acquisition rate of traditional manual sampling in heavy rain weather is less than 60%; when sampling in the wild, problems such as container displacement caused by wind, sample contamination caused by rain splashing, and dust adhesion affecting water collection efficiency often occur.

[0003] These problems make it difficult for traditional precipitation collection equipment to meet the needs of high-precision, long-time continuous sampling, and an intelligent collection scheme with automatic, anti-pollution, high stability and state monitoring functions is urgently needed. SUMMARY

[0004] In order to solve the above-mentioned problems, the present application provides a continuous precipitation intelligent collector and collection method.

[0005] The continuous precipitation intelligent collector and collection method provided by the present application adopts the following technical scheme: In a first aspect, a continuous precipitation intelligent collector is provided, comprising a rotatable bearing component that rotates at a predetermined time interval to drive the sampling container to move to a collection position, a protective cover body that is covered outside the rotatable bearing component to keep the sampling container always in a single sampling position, a water collection component that is connected to the water inlet position of the protective cover body to guide the collected rainwater to the sampling container, and a separation piece arranged inside the water collection component. When the rotatable bearing component rotates to replace a collection position, the separation piece is replaced synchronously to ensure that the precipitation samples collected at different times are independent of each other and are not contaminated.

[0006] Preferably, it further comprises a separation piece replacement mechanism, which replaces the separation piece each time the rotatable bearing component rotates, to ensure that the precipitation samples collected at different times are independent of each other and are not contaminated.

[0007] Preferably, the rotatable bearing component comprises: a base placed in a sampling position and fixed to the ground, a rotating table located above the base and rotating along the center of the base, a driving component arranged in a groove formed in the center of the base and providing driving force required for the rotation of the rotating table, and a container limiting groove opened on the rotating table and matched with the size of the sampling container.

[0008] Preferably, the rotatable bearing component further comprises: a power supply unit providing power support for the operation of the rotatable bearing component.

[0009] Preferably, the protective cover comprises: a sealing cover matched with the size of the rotatable bearing component and covering the outside of the rotatable bearing component, a drainage pipeline located on one side of the sealing cover and used for guiding the overflow of samples inside the sealing cover, a water collection guide opening opened on one side of the upper end of the sealing cover, and the upper end of the sealing cover gradually inclines from the outer end to the water collection guide opening to guide the precipitation into the water collection guide opening.

[0010] Preferably, the water collection component comprises: a water collection guide piece matched with the position of the water collection guide opening and in the shape of a funnel, a guide pipeline located below the water collection guide piece and fixed to the water collection guide piece, and a limiting hook located inside the water collection guide piece and fixed to the inner wall of the water collection guide piece, the limiting hook limiting the position of the isolation piece.

[0011] Preferably, the isolation piece replacement mechanism comprises: an isolation component box fixed to the protective cover, an isolation feeding roller located inside the isolation component box, an isolation receiving roller located inside the isolation component box and arranged in a staggered manner with the isolation feeding roller, and an isolation piece wound outside the isolation feeding roller and wound by the isolation receiving roller after passing through the water collection component.

[0012] In the second aspect, a collection method of the continuous intelligent precipitation collector is provided, which comprises the following steps: S1, placing a clean sampling container matched with the limiting groove of the rotatable bearing component in the limiting groove, loading sufficient isolation pieces on the isolation feeding roller and winding the isolation pieces to the receiving roller, starting the power supply unit to ensure the normal operation of the driving, control and sensing systems, and setting the control system to rotate once per hour and the rotation angle according to the number of containers.

[0013] S2, in the initial state, the first sampling container is accurately aligned with the water collection guide pipeline; during precipitation, rainwater is collected by the protective cover to the water collection guide opening, flows into the current container through the water collection component, and the isolation piece synchronously isolates and protects. Every hour, the rotation instruction is triggered, the driving component drives the rotating table to rotate to a new station, the isolation piece replacement mechanism is started synchronously to recover the old isolation piece and release the new isolation piece, and the isolation piece is positioned by the limiting hook and covers the inside of the water collection component. After the sensor detects that the alignment and the state of the isolation piece are correct, the next cycle is entered, and the operation is repeated until all the containers complete sampling.

[0014] S3, the sensor automatically alarms and suspends the process when an anomaly is detected, and restarts after repair; the drain pipe real-time exports the overflow liquid to prevent pollution; the rotating drive part pre-detects to ensure smooth operation.

[0015] In summary, the present application has the following beneficial technical effects: Through the synchronous replacement mechanism of the rotatable bearing part and the isolation piece, the precipitation sample of each period is received by an independent sampling container, and the isolation piece inside the water collecting part is updated in real time, which avoids the mixing of samples of different periods from the physical layer, and significantly improves the independence and accuracy of the samples.

[0016] Relying on the time sequence control system and the driving module, the equipment can automatically complete the station switching, isolation piece replacement and sample collection at a preset interval (such as 1 hour) without manual intervention, effectively solving the sampling interruption problem caused by the dependence on manual operation of traditional equipment, and is especially suitable for long-term outdoor unattended scenes.

DETAILED DESCRIPTION

[0024] The following is combined with Figures 1-5 The present invention is described in further detail.

[0025] Example 1 The embodiment of the present invention discloses a continuous precipitation intelligent collector. Figures 1 to 4 As shown, the device comprises a rotatable support member 1, a protective cover 2, and a water collection member 4. The rotatable support member 1 rotates at preset time intervals, driving the sampling container 6 to different collection positions. This ensures that different sampling containers 6 are moved to the collection positions at different time periods, thereby obtaining representative precipitation data. The protective cover 2 is located outside the rotatable support member 1, ensuring the stability of the sampling container 6 during the collection process. This prevents wind or other external forces from disturbing the position of the sampling container 6, ensuring accurate and stable sampling. The water collection member 4 is connected to the water inlet of the protective cover 2 and is used to guide rainwater into the sampling container 6. The water collection member 4 is a key component in rainwater collection, ensuring concentrated and efficient precipitation collection. An isolation member 54 is located inside the water collection member 4 to isolate the collected precipitation samples and prevent cross-contamination between samples collected at different time periods. The isolation member 54 is replaced synchronously with each rotation of the rotatable support member 1, ensuring that samples collected at different time periods do not interfere with each other. The coordination between the isolation member 54 and the rotatable support member 1 ensures that precipitation samples from different time periods are isolated and prevented from contamination. The isolation member 54 is replaced synchronously each time the collection position is changed, which can effectively avoid mixing between samples, thereby obtaining high-quality precipitation data.

[0026] In the above embodiment, to further ensure that the isolation member 54 needs to be replaced after each sampling, an isolation member replacement mechanism 5 is installed on one side of the water collection component 4. The primary function of the isolation member replacement mechanism 5 is to automatically replace the isolation member 54 with each rotation of the rotatable support member 1. This ensures that precipitation samples collected during each sampling period are not cross-contaminated with samples from the previous period, thereby ensuring the independence and accuracy of the samples. To meet replacement requirements, sensors are installed within the water collection component 4 and the isolation member replacement mechanism 5 to monitor the status before and after replacement.

[0027] like Figure 3As shown, the rotatable bearing component 1 includes a base 11, a rotating platform 12, a driving component 13, and a container limiting groove 14. The base 11 is used to fix the entire device at the sampling position. The rotating platform 12 is arranged as a rotatable platform above the base 11 and carries the sampling container 6 and rotates along a predetermined path. The rotating platform 12 rotates at a set time interval or angle to ensure that the sampling container 6 enters the sampling position regularly. The rotating platform 12 is arranged in a ring or disc structure and can rotate freely above the base 11 along the central axis of the base 11. The rotating platform 12 uses precision bearings or rolling devices to ensure smooth rotation without jamming and can bear the weight of the sampling container 6 and the sample inside. The driving component 13 is the power source of the entire transmission system, which provides sufficient driving force to enable the rotating platform 12 to complete stable rotation. The driving component 13 ensures that the rotating platform 12 rotates at a set period or angle, thereby ensuring that the sampling container 6 enters the sampling position at the appropriate time. The driving component 13 selects an electric motor, a stepper motor, or a servo motor as the driving source, and selects the appropriate motor type according to the sampling period requirements. The electric motor reduces the rotating speed through a reducer and provides sufficient torque to adapt to long-term stable operation. The driving component 13 is installed in the groove formed in the center of the base 11, which can effectively save space and reduce external interference. The driving component 13 is connected with the rotating platform 12 through a transmission device (gear, belt) to ensure smooth transmission of driving force. In actual use, in order to meet the stability and smoothness of the rotating platform 12, an annular track and a pulley can be installed between the rotating platform 12 and the base 11 to support the rotation of the rotating platform 12 and reduce friction. The container limiting groove 14 is used to ensure the correct position of the sampling container 6 on the rotating platform 12 and prevent displacement during rotation. The size of the limiting groove is matched with the sampling container 6 to ensure the fixation and stability of the container on the rotating platform 12.

[0028] In actual use, the driving component 13 provides power to drive the rotating platform 12 to rotate along the central axis of the base 11. The rotating platform 12 ensures the correct placement and stability of the sampling container 6 through the container limiting groove 14. The rotating platform 12 rotates by a fixed angle, and a new sampling container 6 enters the sampling position, thereby starting a new collection period. In this way, the system can ensure that the sample of each collection period is completely independent of other samples, avoiding cross contamination.

[0029] In the above embodiment, in order to provide power support for the operation of the rotatable bearing component 1, a power supply unit 3 is installed externally, which provides continuous and stable power supply for the entire system, especially the rotatable bearing component 1 (rotating platform 12, driving component 13). The power supply unit 3 also needs to support the operation of the control system, sensor feedback, control panel, and other electronic elements of the system to ensure the automation and precise control of the sampling system.

[0030] AsFigures 1 to 2 As shown, the protective cover 2 includes a sealing cover 21, a drainage pipe 22 and a water collection guide 23. The sealing cover 21 is adapted to the rotatable bearing component 1 and is arranged outside the bearing component. The rotatable bearing component 1 is protected from external factors (water, dust) that may affect the sampling accuracy. The drainage pipe 22 is located on one side of the sealing cover 21 and is used to guide the sample or liquid that may overflow from the inside of the sealing cover 21. This effectively prevents water or liquid from accumulating in the sealing cover 21, ensuring that the sampling accuracy is maintained inside the cover, and preventing the overflow of the material from affecting the equipment. The water collection guide 23 collects and guides the precipitation or overflow of liquid in a specific direction. The upper end of the sealing cover 21 is gradually inclined towards the water collection guide 23 from the outer end. The inclined design helps the liquid sample to flow towards the water collection guide 23, avoiding the liquid to stay in the upper part of the sealing cover 21, which affects the accuracy of subsequent collection.

[0031] As shown, Figure 4 The water collection component 4 includes a water collection guide 41, a guide pipe 42 and a limiting hook 43. The water collection guide 41 is funnel-shaped and is located opposite the water collection guide 23. The funnel-shaped design helps to guide the liquid to flow towards the guide pipe 42. The liquid is guided from a wide area to a narrow outlet, ensuring that the liquid flows to the correct drainage channel. The guide pipe 42 is located below the water collection guide 41 and is fixed thereto. The liquid flowing from the water collection guide 41 is further guided to the sampling container 6. The limiting hook 43 is located on the inner side of the water collection guide 41 and is fixed to the inner wall of the water collection guide 41. The main function of the limiting hook 43 is to limit the position of the isolation piece 54, ensuring that the isolation piece 54 does not move or fall accidentally during use. This ensures the stability of the entire water collection system, preventing water or other liquid from leaking, and ensuring the stability of the automatic replacement of the isolation piece 54.

[0032] As shown, Figure 5As shown, the isolation replacement mechanism 5 includes an isolation component box 51, an isolation pay-off roller 52, an isolation take-up roller 53, and an isolation member 54, which are fixed to the protective cover body 2 as the external frame of the entire isolation replacement mechanism 5. They are used to accommodate other related components. The isolation pay-off roller 52 is located inside the isolation component box 51 and is used to pay out the isolation member 54. The design of the roller ensures that the isolation member 54 can be paid out in an orderly manner, facilitating the subsequent replacement process. The pay-off roller gradually guides the isolation member 54 from the storage state to the next operation. The isolation take-up roller 53 is arranged in a staggered manner with the isolation pay-off roller 52 and is located inside the isolation component box 51. Its function is to collect the isolation member 54 discharged through the water collecting component 4. The arrangement of the take-up roller ensures the recycling of the isolation member 54 during use, avoiding its random scattering or accumulation. The staggered arrangement can optimize the placement and recovery process of the isolation member 54, reducing interference with the equipment. The isolation member 54 is wound outside the isolation pay-off roller 52 and is wound by the isolation take-up roller 53 after passing through the water collecting component 4. The isolation member 54 can be effectively guided and wound as needed, while avoiding exposure to the external environment, maintaining cleanliness and applicability. In actual use, the isolation take-up roller 53 can be driven by a motor to perform the winding work.

[0033] Embodiment 2 On the basis of embodiment 1, a sampling method of a continuous-type intelligent precipitation collector is proposed, including the following steps: S1-1, uniformly place clean sampling containers 6 matching the preset number in the container limiting groove 14 of the rotatable bearing component 1, ensure that each container is size-fitted with the limiting groove and fixed in place; S1-2, check the isolation replacement mechanism 5, load sufficient isolation members 54 on the isolation pay-off roller 52, and ensure that the isolation members 54 pass through the inside of the water collecting component 4 and are correctly wound to the isolation take-up roller 53.

[0034] S1-3, start the power supply unit 3 to ensure that the driving component 13, the control system, and the sensor are in normal working condition.

[0035] S1-4, set the time interval parameter of the control system to 1 hour, so that the rotatable bearing component 1 rotates once every hour, and the rotation angle of each rotation is calculated according to the number of sampling containers 6.

[0036] S2-1, in the initial state, the first sampling container 6 is accurately aligned with the outlet of the flow guide pipe 42 of the water collecting component 4, forming an initial collection station.

[0037] S2-2, when precipitation occurs, rainwater is collected to the water collecting and guiding opening 23 through the inclined upper end surface of the protective cover body 2, flows into the currently aligned sampling container 6 through the water collecting and guiding member 41 and the flow guide pipe 42, and the isolation member 54 inside the water collecting component 4 protects the rainwater during this period.

[0038] S2-3, when the control system is timed for 1 hour, a rotation instruction is triggered: the driving component 13 drives the rotating table 12 to rotate by a preset angle, so that the next sampling container 6 moves to a position opposite to the outlet of the flow guide pipe 42, forming a new collection station. The isolation piece replacement mechanism 5 is started synchronously, the used isolation piece 54 is recovered by rotating the isolation receiving roller 53, and at the same time, the new isolation piece 54 is released by the isolation discharging roller 52, covers the inner side of the water collecting component 4 after being positioned by the limiting clasp 43, and the real-time replacement of the isolation piece 54 is completed. The sensor detects the alignment state of the new sampling container 6 and the installation state of the new isolation piece 54, and after confirming that there is no error, the sampling cycle of the next hour is entered.

[0039] S2-4, repeat steps 2.2-2.3 until all sampling containers 6 complete sampling in the corresponding period.

[0040] S3, if the sensor detects that the container alignment deviates or the isolation piece 54 replacement is abnormal, the system automatically issues an alarm and suspends the sampling process, and after manual intervention for repair, it is restarted. The drain pipe 22 inside the sealing cover 21 can guide the possible overflow liquid in real time to avoid pollution to the unsampled container 6. Before each rotation, the driving component 13 performs pre-start detection to ensure that the rotation process is smooth and free of jamming, and to ensure the accuracy of the container alignment.

[0041] Embodiment 3 On the basis of Embodiment 1 and Embodiment 2, in order to meet the continuous sampling demand, a collection control system is proposed to drive the internal components of the collector to adapt to the sampling function; The system comprises a core control module, a driving control module, a state monitoring module and an alarm module. The core control module comprises a main control unit and a timing control submodule; the main control unit: adopts a microprocessor (STM32 series single-chip microcomputer), receives external instructions, processes sensor data, outputs control signals, and coordinates the orderly work of each module. The timing control submodule is built-in real-time clock (RTC), which generates timing trigger signals according to preset parameters (such as 1 hour interval) for accurate control; The driving control module comprises a bearing component driving submodule and an isolation piece 54 replacement driving submodule; the bearing component driving submodule is electrically connected with the driving component 13 (electric motor / stepping motor / servo motor), receives the rotation instruction of the main control unit, and outputs pulse signals or voltage signals to control the motor to start, stop and rotate at a preset speed, and drives the rotating table 12 to rotate by a preset angle through a reducer and a transmission device.

[0042] The isolation piece 54 replacement driving sub-module is electrically connected with the isolation material collecting roller 53 motor. When the bearing component rotation instruction is triggered, a driving signal is output to control the rotation of the material collecting roller. The old isolation piece 54 is recycled through a preset winding length parameter (matching the rotation angle), and the new isolation piece 54 is released synchronously, so as to ensure the integrity of the isolation piece 54 covering the inner side of the water collecting component 4.

[0043] The state monitoring module comprises a position detection sub-module, an isolation piece 54 state detection sub-module and a device running state monitoring sub-module. The position detection sub-module is connected with the position sensor (infrared sensor, laser displacement sensor) below the water collecting component 4 to detect the relative position of the sampling container 6 and the outlet of the flow guide pipeline 42 in real time. When the deviation exceeds the preset threshold value (≤2 mm), an abnormal signal is sent to the main control unit. The isolation piece 54 state detection sub-module monitors the tension and covering state of the isolation piece 54 through the tension sensor and the photoelectric sensor installed on the inner side of the water collecting component 4. If the isolation piece 54 is detected to be off, broken or not completely covered, abnormal information is immediately fed back. The device running state monitoring sub-module collects parameters such as voltage of the power supply unit 3, current of the driving component 13, environmental temperature and humidity in real time to determine whether the device is in the normal working range (low power alarm is triggered when the power supply voltage is below the threshold value).

[0044] The alarm module comprises an abnormal response sub-module and an alarm output sub-module. When the abnormal response sub-module receives the position deviation, isolation piece 54 abnormality, device failure and other signals sent by the sensor, an interrupt request is immediately sent to the main control unit. The main control unit triggers the protection mechanism to pause the current sampling process, cuts off the power supply of the driving component 13, and records the abnormal occurrence time and type. The alarm output sub-module sends an on-site alarm signal through the sound and light alarm (buzzer + warning light), and supports sending alarm information to the remote monitoring platform through communication modes such as RS485 and NB-IoT, including abnormal type, device ID and location information, for manual intervention and repair.

[0045] The system working process is as follows: After the system is powered on, the main control unit performs a self-checking program to detect the communication state of each module, the sensor connectivity and the parameter configuration integrity. If the self-checking is passed, the system enters the standby state; if there is a fault, the alarm is immediately triggered.

[0046] The timing control sub-module sends a trigger signal at a preset interval (1 hour), and the main control unit sends control instructions to the bearing component driving sub-module and the isolation piece 54 replacement driving sub-module at the same time. The driving component 13 drives the rotating table 12 to rotate to a new station, the isolation material collecting roller 53 synchronously recycles the old isolation piece 54 and releases the new isolation piece 54, and the limiting clasp 43 completes the positioning of the isolation piece 54.

[0047] The state monitoring module detects the alignment accuracy of the new station and the state of the isolation piece 54. If both are normal, the main control unit records the current sampling period information and enters the next cycle waiting. If abnormal, trigger alarm and suspend the process.

[0048] After receiving the abnormal signal, the system immediately stops and records fault information, notifies the operation and maintenance personnel through sound and light alarm and remote communication, and after the fault is repaired and manually reset, restarts the sampling process.
