Abstract
Description
Technical Field
[0001] This utility model relates to the field of water sampling technology, specifically an intelligent multi-depth water sampling device. Background Technology
[0002] In aquatic environmental monitoring and scientific research, accurately collecting water samples at different depths is crucial for analyzing water quality changes, assessing pollution levels, and studying the dynamic changes of aquatic ecosystems. Water quality parameters, such as dissolved oxygen, nutrients, temperature, and pH, typically change significantly with depth. Therefore, obtaining water sample data from different depths is particularly important for a comprehensive and accurate understanding of water conditions.
[0003] Traditional water sampling methods primarily rely on manual or automated sampling. Manual sampling typically involves dropping sampling bottles or samplers to a designated depth. This method has significant limitations: First, manual operation is time-consuming and labor-intensive, especially when multiple depths need to be sampled, requiring the equipment to be submerged and the process repeated for each sample. Second, the repeated operation can cause significant disturbance to the water body, particularly in shallow or flowing water, which can reduce the representativeness of the samples and thus affect the accuracy of water quality data. Furthermore, manual sampling makes it difficult to ensure that samples are collected at the same time, location, and depth, making it challenging to obtain continuous and accurate water quality data across multiple depths. Automated water sampling, when collecting samples at multiple depths, typically uses a telescopic structure to move the sampler to the predetermined depth area. Similarly, the extension and retraction of the sampler during this process disturbs the water body, thus affecting the accuracy of the water quality data. Utility Model Content
[0004] The purpose of this invention is to provide an intelligent multi-depth water sampling device to solve the technical problem that current water sampling devices disturb the water body and thus affect the accuracy of water quality data when collecting water samples from water bodies at different depths.
[0005] The technical solution of this utility model is:
[0006] An intelligent multi-depth water sampling device includes a sampling main pipe, a connecting cover, and a pumping assembly. The lower end of the sampling main pipe is closed, and multiple sampling branch pipes are provided along its height direction on the side wall of the sampling main pipe. Each sampling branch pipe has a solenoid valve at its port, and each solenoid valve is electrically connected to an external controller. The connecting cover includes a cylindrical shell section and a conical connecting pipe. The two ends of the conical connecting pipe are connected to the bottom of the cylindrical shell section and the upper end of the sampling main pipe. The cylindrical shell section has multiple connecting holes along its circumference. The number of connecting holes is the same as the number of sampling branch pipes, and the multiple connecting holes are connected to the multiple sampling branch pipes one-to-one through water supply pipes. The pumping end of the pumping assembly is provided with a connecting pipe, which is detachably connected to one of the connecting holes. By adjusting the position of the connecting pipe to connect to the connecting holes corresponding to sampling branch pipes of different heights, water samples at different depths can be collected.
[0007] Preferably, as a further improvement of this utility model, each of the connecting holes is provided with internal threads, and the end of the connecting pipe away from the pumping assembly is provided with a threaded connector, which is detachably connected to the connecting hole through the threaded connector.
[0008] Preferably, as a further improvement of this utility model, the sampling main tube includes several tubes, each of which is detachably connected by threads at both ends, and the threaded connection is sealed.
[0009] Preferably, as a further improvement of this utility model, a float plate is fixed on the outer wall of the upper port of the sampling tube.
[0010] Preferably, as a further improvement of this utility model, each of the sampling branches is provided with a sensor for monitoring the incoming water sample data.
[0011] Preferably, as a further improvement of this utility model, the water pumping assembly is an electric water pump, and the pumping end of the electric water pump is connected to the connecting pipe.
[0012] Preferably, as a further improvement of this utility model, it also includes a solar power supply component, which is connected to the electric water pump, the sensor and the solenoid valve respectively.
[0013] Preferably, as a further improvement of this utility model, the solar power supply component includes a solar panel, a battery, and a solar controller. The solar panel is fixed to the top of the floating plate and is electrically connected to the battery and the solar controller. The battery is electrically connected to the electric water pump, the sensor, and the solenoid valve.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] Based on the required sampling depth, the connecting pipe is connected to a specific connection hole of the sampling branch pipe at the corresponding sampling depth by adjusting the connection pipe. The solenoid valve is opened by an external controller, and the water pumping assembly is used to collect the water sample at the current sampling depth sequentially through the sampling branch pipe, the water supply pipe, and the connecting pipe. During the entire sampling process at different depths, since it is not necessary to repeatedly put the main sampling pipe into the water or adjust the depth of the main sampling pipe into the water, the disturbance to the water body can be reduced, the original state of the water sample can be maintained, and thus the accuracy of the test can be ensured.

[0020] Example
[0021] like Figures 1 to 2As shown, this utility model embodiment provides an intelligent multi-depth water sampling device, including a sampling main pipe 1, a connecting cover 3, and a pumping assembly 5; the lower end of the sampling main pipe 1 is closed, and multiple sampling branch pipes 2 are provided on the side wall of the sampling main pipe 1 along its height direction. Each sampling branch pipe 2 is provided with a solenoid valve 21 at its port. Each solenoid valve 21 is electrically connected to an external controller. The lower end of the sampling main pipe 1 is closed. The connecting cover 3 includes a cylindrical shell section 31 and a conical connecting pipe 32. The two ends of the conical connecting pipe 32 are connected to the bottom of the cylindrical shell section 31 and the upper end of the sampling main pipe 1. The cylindrical shell section 31 is provided with multiple connecting holes 311 along its circumference. The number of multiple connecting holes 311 is the same as the number of multiple sampling branch pipes 2, and the multiple connecting holes 311 are connected to the multiple sampling branch pipes 2 one by one through a water supply pipe 4. The pumping end of the pumping assembly 5 is provided with a connecting pipe 51, and the connecting pipe 51 is detachably connected to one of the connecting holes 311.
[0022] In this embodiment, multiple sampling branch pipes 2 are used to sample water samples at different depths. During sampling, each solenoid valve 21 is closed. Then, the entire sampling main pipe 1 is placed into the water to be sampled. According to the sampling depth requirements, the connecting pipe 51 is adjusted to connect to a certain connecting hole 311 connected to the sampling branch pipe 2 at the corresponding sampling depth. The solenoid valve 21 is opened by an external controller, and the water sample at the current sampling depth is collected sequentially through the sampling branch pipe 2, the water supply pipe 4, and the connecting pipe 51 using the pumping assembly 5. The drainage end of the pumping assembly 5 is connected to the onshore laboratory or water storage tank to transport the pumped water to the onshore laboratory or water storage tank for subsequent research. During the entire sampling process of water samples at different depths, since it is not necessary to repeatedly put the sampling main pipe 1 into the water or adjust the depth of the sampling main pipe 1 in the water, the water body will not be disturbed significantly, thereby reducing the impact of water disturbance on the accuracy of water quality data detection.
[0023] Specifically, each connection hole 311 has internal threads, and the end of the connection pipe 51 away from the pumping component 5 has a threaded connector, which is detachably connected to the connection hole 311 through the threaded connector.
[0024] Furthermore, in order to expand the sampling depth range, the sampling main tube 1 is set up as several tubes, each tube being detachably connected by threads at both ends, and the threaded connection is sealed. This setup allows the height of the sampling main tube 1 to be changed by increasing the number of tubes, thereby expanding the sampling depth range and enabling the collection of water samples from deeper water areas.
[0025] In order to facilitate the overall positioning of the sampling main pipe 1, a float plate 6 is fixed on the outer wall of the upper port of the sampling main pipe 1. During use, the float plate 6 is used for buoyancy support. At the same time, the float plate 6 is fixed to the shore by fixed anchor rods and other structures to prevent the float plate 6 from moving.
[0026] In order to monitor water quality and transmit data, each sampling branch pipe 2 is equipped with a sensor 7 for monitoring the incoming water sample data. The sensor 7 is composed of any one or more of a temperature sensor, conductivity sensor, pH sensor, dissolved oxygen sensor and turbidity sensor, which can detect water quality and transmit data according to monitoring needs.
[0027] Specifically, the pumping assembly 5 is an electric water pump, and the pumping end of the electric water pump is connected to the connecting pipe 51.
[0028] In another embodiment of this utility model, in order to utilize solar energy to power the electrical equipment in the data collection device to adapt to the field environment, a solar power supply component is included, which is connected to the electric water pump, the sensor 7 and the solenoid valve 21 respectively.
[0029] Specifically, the solar power supply assembly includes a solar panel 81, a battery 82, and a solar controller. The solar panel 81 is fixed to the top of the floating plate 6. The solar panel 81 is electrically connected to the battery 82 and the solar controller. The battery 82 is electrically connected to an electric water pump, a sensor 7, and a solenoid valve 21. The solar panel 81 can collect solar energy and convert it into electrical energy, which is then sent to the battery 82 for storage. The solar controller can control the charging and discharging of solar energy to regulate the power supplied from the solar panel to the battery 82, thus preventing overcharging or over-discharging of the battery 82.
[0030] The sampling tube 1 has at least 5 sampling holes in its body, and the sampling depth is marked on each hole for easy identification.
[0031] Furthermore, a GPS locator 8 is installed on the top of the connecting cover 3 to record the sampling location.
[0032] In practical application, the main sampling pipe 1 consists of three detachable pipes, each 1.5m high and 10cm in diameter. Ten sampling branch pipes 2, each 2cm in diameter, are evenly distributed along the longitudinal sidewall of each pipe. Each sampling branch pipe 2 is fixed to the connection hole 311 via a diameter water pipe 4, ensuring undisturbed sampling. Each sampling branch pipe 2 contains a sensor 7, which monitors and transmits data in real time. A GPS positioning device records the location, a float plate 6 provides stability, an electric water pump draws water samples to a ground storage device via a polyethylene water pipe, a battery 82 provides backup power, and a 5G Wi-Fi communication module enables remote monitoring and control, ensuring efficient and stable operation of the equipment.
[0033] During the sampling process, the equipment is first transported to the target sampling point in a shallow lake. The equipment is placed on the water surface using a float to ensure its stability. The GPS locator 8 is activated to record the sampling location. Then, the sampling depth and time interval are set through the controller. The sensor 7 is activated to monitor parameters such as temperature, conductivity, pH value, dissolved oxygen, and turbidity of the water sample in real time and transmits the data to the controller and the onshore laboratory. The user can remotely monitor the equipment's operating status via Wi-Fi. The electric water pump is periodically activated to transfer the collected water samples through the water pipe 4 to the onshore laboratory storage device for further analysis. At the same time, the solar panel 81 provides continuous power to the equipment, and the battery 82 provides backup power at night or on cloudy days to ensure that the equipment can continue to work under various weather conditions. During the use of the intelligent multi-depth water sampling device of this utility model, cleaning and maintenance work includes regularly checking and cleaning the sampling holes and sensors to ensure the unobstructed flow of the sampling branch pipe 2 and the sensitivity of the sensors; checking the unobstructed flow of the water supply pipe 4 and replacing or repairing any blocked or damaged parts in a timely manner; regularly checking the operating status of the electric water pump and the stability of the float plate to ensure stable operation of the equipment on the water surface; maintaining the solar panel 81 and the battery 82, cleaning the surface of the solar panel to maintain efficient energy conversion, and checking the charge and connection status of the battery 82; ensuring the stable operation of the Wi-Fi communication module and controller, regularly updating and checking the software, and fixing any possible vulnerabilities or errors.
