Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection, in particular to a rainwater sampler. Background Art

[0002] With the rapid advancement of urbanization, urban water pollution is becoming increasingly serious and freshwater resources are becoming increasingly scarce. These problems are particularly prominent. Therefore, scientifically collecting rainwater, a precious water resource, conducting in-depth analysis and utilization, and implementing comprehensive management based on this has become a vital environmental protection measure. Rainwater samplers, as devices specifically used to collect rainwater, play a vital role in environmental monitoring, meteorological research and other fields. They provide us with an important tool for quantitatively collecting rain and snow samples and conducting component analysis.

[0003] However, most of the rainwater sampling devices currently on the market rely on manual operation. Operators need to set up sampling cups at different locations to collect rainwater samples. This method is particularly inconvenient when encountering abnormal weather such as heavy rain. Operators need to pay attention to the sampling situation at all times, which also increases the workload. At the same time, due to the interference of human factors, the accuracy of the sampling results is greatly reduced, which can easily lead to large errors in rainwater sampling and analysis data. In addition, these sampling devices can only collect rainwater for a certain period of time within a specific time, and cannot collect samples in proportion to time, which is not conducive to understanding the changes in pollutant concentrations during rainfall runoff.

[0004] Therefore, we urgently need to find more efficient and accurate rainwater sampling devices to improve the reliability of sampling data. Utility Model Content

[0032] The technical solution of the utility model is described in detail below in conjunction with the embodiments and drawings.

[0033] The utility model provides a rainwater sampler, such as Figure 1 , including: a shell and a rainwater inlet opened on the shell, a sealing cover 1 arranged on the rainwater inlet, a sealing cover driving member 2, a rainwater sensor 3, a driving control member 4, a water storage tank 5, a guide pipe 6, a guide pipe guide assembly 7, a water storage bottle 8 and a plurality of drain ports 10 arranged below the shell; wherein,

[0034] In a specific embodiment, the sealing cover 1 is connected to the sealing cover driver 2; the sealing cover driver 2 is used to drive the opening and closing of the sealing cover 1, and the drive control part 4 is connected to the rain sensor 3 and the sealing cover driver 2 respectively, and the drive control part 4 drives the sealing cover driver 2 to control the opening and closing of the sealing cover 1. When the sealing cover 1 is closed, mosquitoes and dust are prevented from entering the rain collector, and when the sealing cover 1 is opened, rainwater is received. Preferably, the sealing cover driver 2 is a cover opening motor. The rain sensor 3 is used to monitor whether there is precipitation, and is used to detect the weather state. When there is precipitation, it starts and sends a signal to the drive control part 4. The drive control part 4 controls the sealing cover driver 2 to open the sealing cover 1 to receive rainwater, and when the rain stops, it is disconnected and the seal 1 is closed. Among them, the monitoring process of the rain sensor 3 and how to control the triggering drive control part 4 are technical means well known to those skilled in the art. Similarly, how the drive control part 4 triggers the sealing cover driver 2 to drive the opening and closing of the sealing cover 1 is a conventional method in the field, and does not involve improvements in the method.

[0035] The driving control component 4 may also be a driving switch component, which is used to drive the flow guide tube guide assembly 7 to move. The driving process of the driving control component is a conventional technical means in this field and does not involve improvements in the method. The driving control component 4 is connected to the flow guide tube guide assembly 7; the flow guide tube guide assembly 7 includes a linear motor 11 and an electric screw 9 in the X / Y directions. The signal sent by the driving control component 4 drives the flow guide tube guide assembly 7 to move the flow guide tube to the specified position in sequence. Specifically, the electric screw 9 in the X / Y directions is used to move the linear motor. The linear motor 11 is arranged on the electric screw in the X direction. The linear motor 11 moves on the electric screw in the X direction. The electric screw in the X direction moves on the electric screw in the Y direction. The electric screw plays a supporting role, and the driving control component 4 can drive the electric screw to move the position of the linear motor 11, so that the flow guide tube can be moved to the specified position arbitrarily in the X and Y axes in the plane to ensure that it is aligned with the water collection bottle below, such as Figure 2 shown.

[0036] A timer 12 is set in the drive control part 4; the timer 12 is used to record the start and end time of precipitation. The timer 12 can also set several sampling opening periods and closing periods. In the opening period, the drive control part 4 is electrically connected to the guide tube guide assembly 7; in the closing period, the drive control part 4 is disconnected from the guide tube guide assembly 7. Specifically, the sampling interval time (which can be set within 1-60 minutes) is set by the timer, and the drive switch controls the guide tube guide assembly 7 to save the rainwater in this period, thereby controlling the rainwater to be saved in time periods. The sampler controls the linear motor 11 in the guide tube guide assembly 7 to move through the drive control part 4, and the timer 12 can set the time resolution arbitrarily within 1-60 minutes. That is, water samples of different time periods of a precipitation can be saved separately. For example, the timer sets the interval time to 5 minutes, that is, the stepping linear motor 11 is moved once every 5 minutes, and the water samples within 5 minutes will be saved in a water storage bottle 8. Assuming that a precipitation process is set to last for 300 minutes, the water samples of the entire precipitation process will be saved as a sample every 5 minutes, and then saved in 60 water storage bottles. At the same time, the start and end time of precipitation can be recorded. And the precipitation amount can be counted according to the water storage bottle. Preferably, if the rainfall intensity is large, the interval time can be shortened to 2 minutes or 1 minute to ensure the independence of the water storage bottle sample. When the rainfall intensity is small, the interval time can be increased to 10 minutes or 30 minutes. The setting time of the timer is a conventional timer used in this field. Commercially available counters can be used to record time, and time intervals can be set, and then used to start the drive switch to control the guide assembly 7 of the guide tube. This process does not involve improvements in the method and is a conventional technical means in this field.

[0037] The utility model records the start and end time of precipitation through the timer 12, and can be applied according to different research directions of different disciplines. For example, atmospheric chemistry tends to analyze the chemical components of samples in different time periods, so the time interval can be shortened, and the higher degree of sample subdivision is conducive to analyzing the changing trend of pollutants during rainfall. Atmospheric physics can also count the amount of water in the water bottle for daily precipitation intensity monitoring.

[0038] In a specific embodiment, the water trough 5 is arranged below the rainwater inlet, and a groove is opened at the bottom of the water trough 5 to provide an outlet; when the sealing cover 1 is opened, it is used to receive rainwater and introduce the rainwater into the guide pipe 6 through the bottom groove, one end of the guide pipe 6 is connected to the outlet below the water trough 5, and the other end is connected to the guide pipe guide 7; the guide pipe 6 is used to guide rainwater from the water trough 5 into the sampling bottle 8.

[0039] A storage plate is provided below the other end of the guide tube (6) for placing a plurality of water storage bottles 8. The guide tube guide assembly 7 is provided around the water storage bottle and is moved to a designated position according to the time period, so as to be convenient for storing rainwater introduced by the guide tube. For example, 121 water storage bottles can be placed to meet the requirements of rainwater collection at all times.

[0040] like Figure 2 The drain port 10 can be multiple drain ports, one of which can be set below the storage plate and located on the side of the housing, and the other can be set between the storage plate and the water storage tank 5 and located on the side of the housing. The drain port 10 is a mesh grid design for preventing mosquitoes from passing water. The main function is to prevent water from accumulating inside the device when it is misoperated. When it exceeds a certain safety position, rainwater will flow out from the reserved drain port to prevent the electrical equipment in the device from being submerged.

[0041] The utility model provides a rainwater sampler, and its working process is as follows:

[0042] When the rainwater sampler is on standby, the sealing cover 1 is closed and the equipment is sealed to ensure that the sampled water body is not polluted by the external environment. When the rainwater sensor 3 detects precipitation, it sends a signal to the drive control component 4. The timer 12 in the drive control component 4 records the precipitation time, and the drive control component 4 drives the sealing cover drive component 2 to open the sealing cover 1. The rainwater falls into the water storage tank 5 and flows into the sampling bottle through the guide tube 6. The guide tube 6 is fixed to the linear motor 11. The drive control component 4 moves the linear motor 11 on the electric screw in the X direction according to the time interval set by the timer 12, and the electric screw in the X direction moves on the electric screw in the Y direction to ensure that the guide tube 6 is aligned with the water storage bottle 8 for sampling. The process of sending signals in this process is a conventional technical means in this field and does not involve improvements in the method.

[0043] During the rainfall process, in order to explore the changing patterns of various pollutants with rainfall time and to deeply study the conditions of rainwater quality in different time periods, the utility model collects samples in time proportion. Time proportional sampling is conducive to understanding the changes in pollutant concentrations during rainfall runoff. As the rainfall runoff time continues, the concentrations of various pollutants gradually decrease. This time proportional sampling method not only helps to fully understand the changing characteristics of pollutants during rainfall, but also provides strong data support for subsequent water quality analysis and management.

[0044] The utility model does not involve improvement of the method, and its working principle and process are conventional technical means in the field.

[0045] Any content not described in detail in the present invention can be based on the conventional technical knowledge in the field.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not intended to limit it. Although the utility model is described in detail with reference to the embodiments, a person skilled in the art should understand that any modification or equivalent replacement of the technical solution of the utility model does not deviate from the spirit and scope of the technical solution of the utility model, and should be included in the scope of the claims of the utility model.
