Description

Technical Field

[0001] The invention relates to the technical field of water environment, and in particular to an automatic collector and method for collecting water samples at different water depths. Background Art

[0002] As environmental pollution and climate change become increasingly serious, the need for water quality monitoring is becoming more and more urgent. Automatic collectors can monitor water quality without interruption, providing a more convenient and efficient way for water quality monitoring. With the continuous advancement of science and technology, automatic control and data transmission technology have developed rapidly, making the design and manufacture of automatic collectors more feasible and practical. Traditional water quality monitoring requires manual sampling and analysis, which is not only time-consuming and labor-intensive, but also prone to errors.

[0003] Current water depth sample collectors lack hardware and software support, such as databases, Internet of Things communication equipment, data transmission such as Bluetooth, water quality monitoring sensors and other equipment. During the data collection and transmission process, there is a lack of command-based operations, which makes the data lack of real-time and dynamic discontinuity, making it difficult to adapt to changing environmental conditions and complex sampling requirements, which in turn affects the effectiveness of monitoring and the timeliness of decision-making. Summary of the invention

[0004] In order to overcome the shortcomings of the above-mentioned prior art, such as insufficient real-time data and dynamic discontinuity, and difficulty in adapting to changing environmental conditions and complex sampling requirements, the main purpose of the present invention is to provide an automatic water sample collector and method for different water depths. It has the characteristics of automated operation, high efficiency, high precision, real-time performance, stability, etc., and can be applied to water quality detection, analysis of plankton in water, scientific research and investigation, etc.

[0005] To achieve the above object, the present invention adopts the following technical scheme: an automatic water sample collector of different water depths, comprising a box, wherein the box is provided with:

[0006] Environmental monitoring module, including water quality sensor and water depth sensor, to obtain real-time monitoring data of water depth parameters and water quality parameters;

[0007] A control and communication module is used to receive real-time monitoring data and issue control instructions when the water depth parameter reaches a set threshold range;

[0008] The sampling control module includes a control component, a driving mechanism, a rotating sampling frame, a plurality of sampling bottles evenly arranged on the rotating sampling frame, and a blocking buckle. The lower end of the blocking buckle is located between adjacent sampling bottles. When the control component receives a control instruction, it controls the driving mechanism to drive the rotating sampling frame to rotate, so that a sampling bottle on the rotating sampling frame is opposite to the valve position. At the same time, the sampling control module controls the valve to open for sampling. When the valve is fully opened, it is opposite to the bottle mouth of the sampling bottle to collect underwater water samples.

[0009] The rotating sampling rack comprises:

[0010] A rotating frame is rotatably arranged on the inner wall of the box body through a driving device;

[0011] A plurality of fixing rods are evenly arranged along the radial direction, and one end of the fixing rods is fixedly connected to the rotating frame;

[0012] The plurality of sampling bottles are detachably connected to the other ends of the plurality of fixing rods;

[0013] One end of the blocking buckle is fixedly connected to the inner wall of the box body, and the other end is located between two adjacent sampling bottles.

[0014] It also includes a diving module, including a detachable counterweight block and a buoyancy device. The central axis of the counterweight block coincides with the central vertical line. The buoyancy device has a built-in airbag, which receives control instructions, reaches a preset threshold water depth, controls the airbag to change the buoyancy, maintains positioning at the set water depth, and performs subsequent sampling work.

[0015] The blocking buckle includes: a connecting rod, one end of which is fixedly connected to the side wall of the box body; a blocking rod, one end of which is elastically connected to the lower end of the connecting rod through a torsion spring, and the other end of which is located between two adjacent sampling bottles.

[0016] The counterweight system equipment itself uses fixed or adjustable metal blocks or other high-density materials. The weight can be changed by loading or unloading counterweight blocks to cope with external environmental disturbances such as water flow rate, assisting it in diving stably and at an appropriate speed. At the same time, the center of gravity of the equipment needs to be reasonably arranged to ensure that the equipment remains stable during the dive and avoids tilting or flipping to resist external disturbances. The appearance of the equipment is designed to be streamlined to reduce water resistance during the dive, thereby making the dive process smoother.

[0017] Buoyancy adjustment device: The device is equipped with an inflatable and deflated air bag. The buoyancy is changed by adjusting the amount of gas in the air bag, thereby controlling the diving speed and stability of the device. The inflation pump / deflation valve is used to adjust the inflation and deflation of the air bag, accurately controlling the inflation and deflation of the air bag to ensure that the buoyancy of the device is effectively managed.

[0018] Steps to implement gravity-assisted diving

[0019] Equipment inspection to ensure that all components such as the main body, control and communication module, sampling bottle, etc. are installed intact; check the counterweight system to ensure that the total weight of the equipment is suitable for diving. Press the power button to start the control and communication module, and enter the target diving depth; put the device into the water, and the weight of the device will make it sink naturally; the current depth is monitored by the depth sensor, and the data is transmitted to the control module. The threshold is set. When approaching the target depth, the airbag begins to inhale and expand, increasing the buoyancy of the device and slowing down the diving speed. The target depth position is accurately controlled by the auxiliary thruster to achieve the purpose of stabilizing the device.

[0020] The device is equipped with small electric thrusters to assist in diving and precise positioning. When approaching the target depth, the thrusters are fine-tuned to ensure the stability of the device.

[0021] Water depth control system and real-time monitoring module

[0022] Install a depth sensor: Use a high-precision pressure sensor or ultrasonic depth gauge to monitor the current water depth in real time.

[0023] Data transmission: The depth sensor transmits real-time depth data, as well as water sample parameters that must be monitored in real time, to the control and communication module.

[0024] Feedback control: Develop mobile phone applications for monitoring and data reception, and automatically adjust buoyancy and thrusters based on real-time depth data to ensure a smooth dive.

[0025] Target Depth Confirmation: The control system confirms that the device has reached the target depth and stabilized its position.

[0026] The control and communication module also includes a control panel for inputting control commands and displaying water depth data in real time.

[0027] A method for automatically collecting water samples at different water depths, comprising the following steps:

[0028] Dive after inputting the set water depth command through the control panel of the control and communication module;

[0029] After receiving the water depth instruction, the diving module controls the diving depth. At the same time, the environmental monitoring module monitors the diving depth in real time and sends the monitored depth to the control panel of the control and communication module to display the real-time diving depth, and confirms whether the water depth reaches the set threshold range. If it reaches the set threshold range, it sends a control instruction to the sampling control module;

[0030] The control component in the sampling control module receives the control instruction and drives the rotating sampling frame to rotate, so that a sampling bottle on the rotating sampling frame is opposite to the valve position. At the same time, the sampling control module controls the valve to open for sampling. When the valve is fully opened, it is opposite to the bottle mouth of the sampling bottle to collect underwater water samples; when the control valve is opened for a set time, it is closed to complete the water sample collection at a depth;

[0031] Repeat the above steps multiple times, input different water depth instructions, and complete the water sample collection at different water depths.

[0032] Compared with the prior art, the beneficial effects of the present invention are as follows: through the control and communication module, the function of automatically collecting water samples according to the preset water depth is realized, the environmental monitoring module can monitor and feedback the water depth data in real time, ensure that the collector accurately reaches the set depth, accurate water depth monitoring and control, the energy supply module ensures that the collector can work stably under different environmental conditions, and realizes a stable energy supply. The design of the sampling control module ensures the safety and reliability of the sampling process, and ensures a safe and reliable sampling process. By accurately controlling the sampling depth, more accurate water quality data can be obtained. By adjusting the diving module, the collector can be applied to water bodies of different depths. The control panel of the control and communication module makes the operation more intuitive and convenient, and the real-time display of monitoring data helps to adjust the sampling strategy in time.

[0033] In summary, this automatic water sample collector for different water depths achieves efficient, accurate and automated water depth and water sample collection through a series of technical means. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0039] The present invention will be further described below in conjunction with the accompanying drawings and implementation modes.

[0040] Current water depth sample collectors lack hardware and software support, such as databases, Internet of Things communication equipment, data transmission such as Bluetooth, water quality monitoring sensors and other equipment. During the data collection and transmission process, there is a lack of command-based operations, which makes the data lack of real-time and dynamic discontinuity, making it difficult to adapt to changing environmental conditions and complex sampling requirements, which in turn affects the effectiveness of monitoring and the timeliness of decision-making.

[0041] To solve the above technical problems, see Figure 1 , an automatic water sample collector of different water depths is proposed, including a box body, and the box body is provided with:

[0042] Used to provide power energy supply module 1, which is a combination of battery and solar energy;

[0043] The environmental monitoring module is equipped with relevant water quality sensors 3 and water depth sensors 11 to monitor and collect water depth parameters and water quality parameters in real time;

[0044] The control and communication module 12 is used to receive real-time data monitoring data, the first display panel 2 includes water depth parameters and water quality parameters that are monitored and collected in real time, and is equipped with a database. When the water depth parameter reaches a set threshold range, a control instruction is issued, and the second display panel 13;

[0045] The sampling control module 8 includes a control member and a driving mechanism 4, a rotating sampling frame and a blocking buckle 5, wherein the lower end of the blocking buckle 5 is located between adjacent sampling bottles 9 on the rotating sampling frame. When the control member receives a control instruction, the driving mechanism 4 drives the rotating sampling frame to rotate, so that a sampling bottle 9 on the rotating sampling frame is opposite to the valve 10, and the valve 10 is controlled to open for sampling. When the valve 10 is fully opened, it is opposite to the bottle mouth of the sampling bottle 9 to collect underwater water samples;

[0046] The rotating sampling frame for rotating and replacing the sampling bottle 9 includes:

[0047] The rotating frame is rotatably arranged on the inner wall of the box body through a driving device; multiple fixed rods 15 are evenly arranged along the radial direction, and one end is fixedly connected to the rotating frame; multiple sampling bottles 9 are detachably connected to the other end of the multiple fixed rods 15; one end of the blocking buckle 5 is fixedly connected to the side wall of the box body, and the other end is located between two adjacent sampling bottles.

[0048] The blocking buckle 5 comprises:

[0049] A connecting rod 5-1, one end of which is fixedly connected to the side wall of the box;

[0050] One end of the blocking rod 5 - 2 is elastically connected to the lower end of the connecting rod 5 - 1 through a torsion spring, and the other end is located between two adjacent sampling bottles 9 .

[0051] The environmental monitoring module includes multiple sensors, which are two types of sensors: water depth sensors and water quality sensors, to obtain real-time monitoring data of water depth parameters and water quality parameters.

[0052] In order to ensure stable sampling at different water depths and ensure the effectiveness and diversity of sampling, a diving module 14 is also included, including a detachable counterweight block 6 and a buoyancy device 7. The central axis of the counterweight block 6 coincides with the central vertical line. The buoyancy device 7 has a built-in airbag that receives control instructions. When the preset threshold water depth is reached, the airbag is controlled to change the buoyancy to maintain positioning at the set water depth for subsequent sampling work.

[0053] The control and communication module also includes a control panel for inputting control commands and displaying water depth and water quality data in real time.

[0054] Example 1

[0055] See also Figure 2 , a method for automatically collecting water samples at different water depths, comprising the following steps:

[0056] Dive after inputting the set water depth command through the control panel of the control and communication module;

[0057] After receiving the water depth instruction, the diving module controls the diving depth. At the same time, the environmental monitoring module monitors the diving depth in real time and sends the monitored depth to the control panel of the control and communication module to display the real-time diving depth, and confirms whether the water depth reaches the set threshold range. If it reaches the set threshold range, it sends a control instruction to the sampling control module;

[0058] The control component in the sampling control module receives the control instruction and drives the rotating sampling frame to rotate, so that a sampling bottle on the rotating sampling frame is opposite to the valve position. At the same time, the sampling control module controls the valve to open for sampling. When the valve is fully opened, it is opposite to the bottle mouth of the sampling bottle to collect underwater water samples; when the control valve is opened for a set time, it is closed to complete the water sample collection at a depth;

[0059] Repeat the above steps multiple times, input different water depth instructions, and complete the water sample collection at different water depths.

[0068] 4. Dive to the set depth

[0069] Start the diving program, and the device will assist in diving through gravity control; monitor the current water depth in real time to ensure that the equipment reaches the set target water depth; control the airbag to start inhaling, and use the thruster to fix the equipment at the corresponding water depth.

[0070] 5. Sampling process

[0071] Confirm that the equipment has reached the set water depth and is ready for sampling; the sampling control module 8 receives the control instruction, controls the driving mechanism 4 to drive the rotating sampling frame to rotate, so that a sampling bottle 9 on the rotating sampling frame is opposite to the valve 10, and at the same time the sampling control module 8 controls the valve 10 to open for sampling. When the valve 10 is fully opened, it is opposite to the bottle mouth of the sampling bottle to collect underwater water samples; at the same time, the environmental monitoring module monitors and records water quality parameters such as temperature, pH, turbidity, etc. in real time during the sampling process; relevant real-time monitoring data is automatically uploaded to the database, and the data can be displayed on the real-time monitoring panel.

[0072] Since some parameters require real-time environmental monitoring at the time, and some parameters must be analyzed and extracted in a short period of time, a water quality monitoring function is needed, and deep sampling can be done once, and parameters can be extracted and saved once. Multi-layer sampling requires multi-layer water sample quality results.
