Description

Technical Field

[0001] This invention relates to the field of precipitation collection technology, and in particular to an automatic precipitation collection device and method. Background Technology

[0002] Current precipitation collection methods mostly use open rain collection buckets or semi-automatic collectors, which are prone to sample contamination and evaporation. They are also subject to long-term open-air storage, during which dust can easily enter the sample. After precipitation ends, sunlight exposure causes the sample to evaporate, altering the concentration of isotopes or chemical components in the water. Furthermore, it cannot perform time-series sampling. Traditional equipment mostly collects mixed samples, making it difficult to accurately sample different periods (such as initial and later rainfall) during a single precipitation event. It also requires frequent maintenance, necessitating manual field trips to replace containers, making continuous monitoring difficult in remote areas or extreme weather conditions. The defects stem from the lack of intelligent cover sealing mechanisms and multi-station diversion switching logic in traditional devices, resulting in sampling accuracy being greatly affected by environmental interference and a low degree of automation. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic precipitation collection device and method, which realizes intelligent processing from sensing rainfall to collecting samples in separate bottles, greatly reducing labor costs and improving precipitation collection efficiency. It effectively prevents sample evaporation, oxidation, or secondary pollution from the outside world, ensuring that the collected rainwater samples accurately reflect the precipitation composition at the time and place, and providing highly scientific data. Collecting multiple bottles of samples in chronological order is of great significance for studying the changes in pollutant concentrations during rainfall (such as acid rain evolution and initial rainwater pollution load). Combined with photovoltaic power supply components and a stable support assembly, the device has a strong ability to work independently in the field.

[0004] To achieve the above objectives, the present invention also provides an automatic precipitation collection device, including a support assembly, a rainwater collection assembly mounted on top of the support assembly, several photovoltaic panels mounted on both sides of the rainwater collection assembly, a precipitation sensor mounted on top of one of the photovoltaic panels, the precipitation sensor being connected to the rainwater collection assembly, a filter screen mounted on top of the rainwater collection assembly, an electric turntable mounted on bottom of the rainwater collection assembly, several collection bottles evenly arranged on the circumference of the electric turntable, a motor connection hole mounted at the center of the electric turntable, a turntable motor connected below the motor connection hole, and a controller mounted on the turntable motor.

[0005] Preferably, the support assembly includes a base, and a plurality of support legs are evenly arranged on the circumference of the base surface. The rainwater collection assembly is connected to the top of the support legs, and the controller and the turntable motor are mounted on the base.

[0006] Preferably, the rainwater collection assembly includes a collection tank, an electrically operated sealing plate is provided inside the collection tank, an electrically operated rotating rod passes through the electrically operated sealing plate, the electrically operated rotating rod extends out of the side of the collection tank and is connected to a rotary motor, the rotary motor is connected to the precipitation sensor, a filter screen is provided above the electrically operated sealing plate, a conical funnel is provided at the bottom of the collection tank, and an electrically operated turntable and a collection bottle are provided below the conical funnel.

[0007] Preferably, the collection bottle includes a bottle body, and a sealing flap is provided inside the bottle body. A rotating rod is connected through the sealing flap. Both ends of the rotating rod extend out from the rotating rod connection port provided on the outside of the bottle body near the top. One end of the rotating rod is connected to a return spring, and the other end of the return spring is connected to a fixing hole.

[0008] Preferably, rubber sleeves are provided between the electric sealing plate and the inner wall of the collection tank, and between the sealing flap and the inner wall of the collection bottle.

[0009] Preferably, the photovoltaic panel is electrically connected to the controller, the turntable motor, the precipitation sensor, and the rotating motor.

[0010] To achieve the above objectives, the present invention also provides an automatic precipitation collection method, comprising the following steps: S1. The precipitation sensor collects precipitation information and transmits it to the controller; S2. The controller determines whether to activate the electric sealing plate based on the rainfall information collected by S1. After the electric sealing plate in S3 and S2 is opened, rainwater enters the collection tank through the filter screen, and the controller transmits an electrical signal to the electric turntable to start the timing. In S4 and S3, the rainwater in the collection tanks is concentrated at one point through the structure of a conical funnel and then transported to the collection bottle. After the electric turntable in S5 and S3 finishes timing, it rotates to one collection bottle station, and the next collection bottle continues to be collected.

[0011] Preferably, the controller in S2 determines whether to activate the electric sealing plate based on the rainfall information under the following conditions: If the rainfall exceeds 10ml, the electric sealing plate will be turned on; if the rainfall does not exceed 10ml, the electric sealing plate will be turned off.

[0012] Preferably, the timing rotation of the electric turntable in S3 is set to rotate one workstation every 30 minutes.

[0013] Therefore, the automatic precipitation collection device and method of the present invention, which adopts the above-described content, has the following beneficial effects compared with the prior art: 1. This application eliminates the need for manual supervision throughout the entire precipitation collection process, achieving full-process intelligentization from sensing rainfall to bottle collection, greatly reducing labor costs, improving precipitation collection efficiency, and possessing strong independent field work capabilities. 2. This application ensures the quality of the sample from multiple dimensions. Physical impurities are removed by filtering the filter screen, and the sealed environment formed by the sealing flap and rubber sleeve inside the collection bottle effectively prevents the sample from evaporating, oxidizing, or being contaminated by the outside world. This makes the collected rainwater sample truly reflect the precipitation composition at that time and place, and the data is highly scientific. 3. It has the ability to collect samples in segments. Through the cooperation of an electric turntable and multiple collection bottles, this device can not only collect rainwater, but also collect samples in segments and collect multiple bottles of samples in chronological order. This is of great significance for studying the changes in pollutant concentrations during rainfall (such as acid rain evolution and initial rainwater pollution load).

[0017] In the description of this invention, it should be noted that the terms "upper," "lower," "inner," "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of this invention is usually placed when in use. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0018] Example like Figures 1-2 As shown, an automatic precipitation collection device of the present invention includes a support component 1, a rainwater collection component 2 disposed on top of the support component 1, several photovoltaic panels 3 disposed on both sides of the rainwater collection component 2, a precipitation sensor 4 disposed on top of one of the photovoltaic panels 3, the precipitation sensor 4 being connected to the rainwater collection component 2, a filter screen 5 disposed on top of the rainwater collection component 2, an electric turntable 6 disposed at the bottom of the rainwater collection component 2, several collection bottles 7 evenly disposed on the circumference of the surface of the electric turntable 6, a motor connection hole 8 disposed at the center of the electric turntable 6, a turntable motor 9 connected below the motor connection hole 8, and a controller 10 disposed on the turntable motor 9; the filter screen 5 disposed on top can effectively intercept impurities such as leaves and large dust particles in the rainwater, preventing pipe blockage and ensuring the initial cleanliness of the collected samples; precise rainfall sensing and control, the precipitation sensor 4 can monitor the rainfall status in real time, when rainfall is detected, the signal is transmitted to the controller 10 to control the operation of the rotary motor 24, realizing automatic start-up without manual intervention.

[0019] The support assembly 1 includes a base 11, with several support legs 12 evenly distributed around the circumference of the base 11. The top of each support leg 12 is connected to a rainwater collection assembly 2. The controller 10 and the turntable motor 9 are mounted on the base 11. The base 11 and the evenly distributed support legs 12 form a stable support structure that can effectively cope with severe outdoor weather (such as strong winds) and ensure that the entire device does not tip over. The space is used efficiently by placing the core electrical components such as the controller 10 and the turntable motor 9 on the base 11, which not only lowers the center of gravity of the device and enhances its stability, but also prevents the electrical components from being exposed to moisture under the collection assembly for a long time. It also makes it easier for maintenance personnel to operate and repair the control part from the ground.

[0020] The rainwater collection component 2 includes a collection tank 21, inside which is an electrically operated sealing plate 22. An electrically operated rotating rod 23 runs through the electrically operated sealing plate 22, extending out of the side of the collection tank 21 and connected to a rotary motor 24. The rotary motor 24 is connected to a precipitation sensor. A filter screen 5 is installed above the electrically operated sealing plate 22, and a conical funnel 25 is installed at the bottom of the collection tank 21. An electrically operated turntable 6 and a collection bottle 7 are installed below the conical funnel 25. During non-rainfall periods, the electrically operated sealing plate 22 inside the collection tank 21 is closed, effectively preventing the evaporation of residual moisture inside the tank. It also prevents external dust and foreign objects from entering the collection tank 21 during non-collection periods, ensuring a clean collection environment. The conical funnel 25 at the bottom uses gravity to allow rainwater to smoothly slide into the collection bottle 7 below, reducing rainwater residue and adhesion on the tank wall and improving collection efficiency.

[0021] The collection bottle 7 includes a bottle body 71, inside which a sealing flap 72 is installed. A rotating rod 73 is connected through the sealing flap 72. Both ends of the rotating rod 73 protrude from rotating rod connection ports 74 located on the outside of the bottle body 71 near the top. One end of a return spring 75 is connected to each end of the rotating rod 73, and the other end of the return spring 75 is connected to a fixing hole 76. The collection bottle 7 is rotated by an electric turntable 6. With the control of the turntable motor 9, multiple collection bottles 7 can be automatically switched. This allows the device to collect rainwater in segments according to time sequence or rainfall (e.g., For example, rainwater can be collected after initial runoff or collected in one bottle every half hour, providing conditions for subsequent analysis of changes in rainwater composition over time. When the collection bottle 7 is rotated to the bottom of the conical funnel 25 to collect rainwater, the pressure of the rainwater falling in the conical funnel 25 can open the sealing flap 72 to collect the water. After it is full, the electric turntable 6 rotates, and the sealing flap 72 automatically closes under the action of the return spring 75 (or remains closed in the non-water-collecting position). This design effectively prevents the evaporation of moisture from the collected samples, ensures the stability of the sample concentration, and also prevents cross-contamination between different samples.

[0022] Rubber sleeves 13 are provided between the electric sealing plate 22 and the inner wall of the collection tank 21, and between the sealing flap 72 and the inner wall of the collection bottle 7. These greatly enhance the sealing performance, ensuring not only the sealing and dustproof effect of the device when not in operation, but also preventing rainwater leakage during the collection process and ensuring the accuracy of the collection volume.

[0023] The photovoltaic panel 3 is electrically connected to the controller 10, the turntable motor 9, the precipitation sensor 4, and the rotating motor 24. The photovoltaic panel 3 is set on both sides of the data collection component and can use solar energy to convert into electrical energy to power the controller 10, the motor, the sensor and other power-consuming components. This design eliminates the dependence on mains power and allows the device to be flexibly deployed in remote areas such as the wilderness and mountains where there is no power supply, which greatly expands the scope of application.

[0024] like Figure 3 As shown, an automatic precipitation data collection method of the present invention includes the following steps: S1. The precipitation sensor collects precipitation information and transmits it to the controller; S2. The controller determines whether to activate the electric sealing plate based on the rainfall information collected by S1. The controller determines whether to activate the electric sealing plate based on rainfall information under the following conditions: If the rainfall exceeds 10ml, the electric sealing plate will be turned on; if the rainfall does not exceed 10ml, the electric sealing plate will be turned off. After the electric sealing plate in S3 and S2 is opened, rainwater enters the collection tank through the filter screen, and the controller transmits an electrical signal to the electric turntable to start the timing. The timing of the electric turntable rotation is set to rotate one workstation every 30 minutes; In S4 and S3, the rainwater in the collection tanks is concentrated at one point through the structure of a conical funnel and then transported to the collection bottle. After the electric turntable in S5 and S3 finishes timing, it rotates to one collection bottle station, and the next collection bottle continues to be collected.

[0025] Therefore, the present invention provides an automatic precipitation collection device and method based on the above-mentioned content, realizing intelligent processing from sensing rainfall to bottle collection, greatly reducing labor costs and improving precipitation collection efficiency; effectively preventing sample evaporation, oxidation, or secondary pollution from the outside world, ensuring that the collected rainwater samples can truly reflect the precipitation composition at that time and place, and the data has strong scientific validity; collecting multiple bottles of samples in chronological order is of great significance for studying the changes in pollutant concentrations during rainfall (such as acid rain evolution and initial rainwater pollution load); combined with photovoltaic power supply components and stable support components, the device has extremely strong independent field operation capabilities.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them.
