Description

TECHNICAL FIELD

[0001] The application relates to the technical field of liquid detection sampling, and in particular to a water source sampling and analyzing system for intelligent environmental monitoring. BACKGROUND

[0002] Water is the source of life, and water source water use is related to all aspects of people's life. Literature (Resource Conservation and Environmental Protection, Application of Water Quality Online Monitoring System in Drinking Water Source, Author: Zhao Yang, 2021, (04): 56-57) points out that water bodies are often affected by changes in external natural environment climate temperature and chemical plant sewage discharge, and need to be monitored to protect the water source and avoid pollution incidents in the water source.

[0003] Traditional water source sampling and analysis mostly uses manual sampling with sampling auxiliary equipment, such as HX-A multifunctional water quality sampler, the product company website is: http: / / www.cod178.cn / Products-34671815.html. After sampling, the detection personnel need to send the sampled water into professional detection instruments for special parameter detection. At the same time, the detection personnel use portable acid-base test paper and thermometer to monitor the acid-base value and temperature of the water source. Since water sampling is not only for one detection point, but also needs detection personnel to repeat the above sampling operation in different flow sections of the river water source, it is necessary to consume manpower to different flow sections of the river, and to sample different special parameters, and finally to consume manpower to collect and transport the samples. Therefore, the manual sampling method is not efficient.

[0004] According to the above problems, the prior art provides a sampling method using unmanned, which solves the problem of low efficiency of manual sampling. Application No. CN202111146891.8 discloses a unmanned aerial vehicle sampling device, which uses a unmanned aerial vehicle as a carrier to carry a sample bottle, and the sampling bracket below the unmanned aerial vehicle collects the sample water into the sample bottle. Although the unmanned aerial vehicle sampling replaces the manual sampling, it is limited by the load capacity and working mode of the unmanned aerial vehicle. For the sampling demand of multiple batches and large water volume, the unmanned aerial vehicle needs to sample back and forth multiple times, which is not efficient. At the same time, in the lake and river, it is difficult for the unmanned aerial vehicle to sample the water source at the same position every time. In addition, since the unmanned aerial vehicle needs to transport the water sample, it is impossible to monitor the conventional parameters of the sampling flow section in real time.

[0005] Therefore, according to the above problems, a water source sampling and analyzing system for intelligent environmental monitoring is provided. SUMMARY

DETAILED DESCRIPTION

[0042] The specific structure of the water floating detection platform in the embodiment is as follows: including a shell 1, a sampling mechanism and a monitoring assembly 4;

[0043] The shell 1 is composed of a conical bottom and a columnar top; the diameter of the shell 1 is 400 mm, and the height is 350 mm; in the embodiment, special parameters in the water source, such as microbial indicators or electromagnetic radiation and other factors, are monitored by sending the water sample to professional equipment after sampling; the sampling mechanism is arranged in the shell 1 and includes a water pumping part, a rotating assembly and a water injection assembly; the water pumping part is coaxially installed at the top of the shell 1, which pumps the sample water into the sampling mechanism; the rotating assembly is coaxially installed in the shell 1, and the rotating assembly sends the sample bottle into the water injection assembly after filling the sample water, and then sends it into the unmanned aerial vehicle; the water injection assembly is arranged at the top of one side of the shell 1, and the water injection assembly injects sample water into the sample bottle in the transmission process of the rotating assembly by inserting the water injection; the shell 1 is integrally formed by polyethylene PE material.

[0044] If the special parameters in the water source are not monitored, these substances that are not easy to be detected can easily cause adverse effects; for example, because the number of microorganisms in the water tank of the waterworks is too large, and the waterworks does not add a special microorganism treatment process, the subsequent purification equipment has a large purification load; therefore, the service life of the purification equipment is shortened, and the maintenance time and cost are increased.

[0045] At the same time, in order to complete the monitoring of the conventional parameters of the water sample, the monitoring assembly 4 is arranged at the bottom of the shell 1, which monitors the conventional parameters of the sample water by light detection, and uploads the monitoring data to the water quality monitoring center through the control system; and the monitoring of the dynamic data change of the conventional parameters of the water sample, especially the change of the conventional parameters such as pH value and oxygen content in the breeding river section, pollution treatment pool and even wild rivers; is conducive to the monitoring personnel to specify the corresponding treatment scheme according to the conventional parameters of the water quality; for example, different breeding aquatic products in the breeding river section have different adaptive values of the basic conventional parameters, and the breeders can adjust the water quality of the water source according to the feedback of the conventional parameters.

[0046] Since the water source of the present application is mostly placed outdoors, it is mostly in an open-air state; and the open-air condition is not conducive to power transmission, so in the present embodiment, the top of the shell 1 is provided with a power generation assembly for energy utilization using solar energy; the power generation assembly includes a solar panel and a battery; the size of the solar panel is 550*550mm; the solar panel is electrically connected with the battery; the battery is electrically connected with the control system; the battery is a lithium ion battery, and its capacity is 20-25 ampere-hours; the solar panel can collect outdoor light energy as working power and store it in the battery; thus, the unmanned and intelligent level of the present embodiment is improved, and the working stability of the system is improved.

[0047] Referring to Figures 3-4 In a preferred embodiment of the present application, the rotating assembly includes a rotating motor 21, a driving disc 22, a first rotating shaft 23, a driven disc 24 and a conveying belt 25.

[0048] The rotating motor 21 is fixedly installed inside the shell 1; the rotating motor 21 adopts a brushless motor, and its power is 50-150w; a driving gear is coaxially and fixedly installed on one side of the driving disc 22; a vertical sliding pin 221 is arranged on the other side of the driving disc 22; the horizontal distance between the sliding pin 221 and the center shaft of the driving shaft is three-fourths of the radius of the driving disc 22; the driving disc 22 is engaged with the output end of the rotating motor 21 through the driving gear; the first rotating shaft 23 is vertically installed inside the shell 1; the driven disc 24 is sleeved on the bottom of the first rotating shaft 23; a U-shaped groove 241 is formed on the driven disc 24 along its horizontal center shaft; the width of the U-shaped groove 241 is equal to the diameter of the sliding pin 221; a plurality of U-shaped grooves 241 are annularly arranged around the vertical center shaft of the driven disc 24; the sliding pin 221 of the driving disc 22 slides in the U-shaped groove 241.

[0049] The conveying belt 25 has a circular ring structure; a gear ring is coaxially arranged on the bottom side of the conveying belt 25; the conveying belt 25 is coaxially and rotatably installed on the top wall of the shell 1; a driven gear is sleeved on the top of the first rotating shaft 23; the driven gear is engaged with the gear ring of the conveying belt 25; the conveying belt 25 is used to drive the sample bottle to rotate around the center shaft of the shell 1; the driving disc 22, the first rotating shaft 23, the driven disc 24 and the conveying belt 25 all adopt polyethylene PE material, and their hardness is about 90D.

[0050] In order to quickly and continuously inject water samples into the sample bottle, the transmission device adopts a rotating motion form; when the unmanned aerial vehicle device is parked on one side of the present application, the sample bottle conveying device on the unmanned aerial vehicle places the idle sample bottle on the conveying belt 25; at this time, the rotating motor 21 rotates, which drives the driven disc 24 to rotate intermittently through the driving disc 22; at the same time, since the first rotating shaft 23 is coaxially and fixedly installed with the driven disc 24, the first rotating shaft 23 also starts to rotate intermittently; therefore, the first rotating shaft 23 drives the conveying belt 25 to rotate around its center shaft.

[0051] Referring to Figures 1-4 In a preferred embodiment of the present application, in order to enable the sample bottle to be accurately injected with water sample by the water injection assembly, and to improve the working stability and efficiency of the sampling mechanism, the conveying belt 25 is provided with a hole matching the cross-sectional shape of the sample bottle, and the inner wall bottom surface of the hole is provided with gel; in this way, when the conveying belt 25 rotates, the sample bottle will be accurately placed in the hole by the unmanned aerial vehicle; therefore, the sample bottle can not only be kept stable, but also can keep the water sample accurately injected into the sample bottle when the rotating assembly transfers the sample bottle into the water injection assembly for water injection, so as to keep the water injection amount of the sample bottle stable; and the gel provided in the hole can fix the sample bottle, so that the sample bottle will not be shaken and fallen due to the water wave impact on the shell 1.

[0052] Since the top of the sample bottle is provided with a sealing cover in the form of a sports drink nozzle, it is necessary to insert the water injection nozzle into the sample bottle from the sealing cover; therefore, in a preferred embodiment of the present application, the water injection assembly comprises a water tank 31, a nozzle 32 and a reciprocating motion assembly 33; the water tank 31 is located at the top of the shell 1; the nozzle 32 is installed at the bottom of the shell 1 through the reciprocating motion assembly 33; the nozzle 32 is communicated with the water tank 31 through a pipeline; the nozzle 32 is used for injecting the water sample in the water tank 31 into the sample bottle on the conveying belt 25; the nozzle 32 is made of ceramic material; the reciprocating motion assembly 33 is used for driving the nozzle 32 to make reciprocating linear motion in the vertical direction; the water tank 31, the nozzle 32 and the reciprocating motion assembly 33 are all made of polyethylene PE material, and the hardness thereof is about 90D.

[0053] In the present embodiment, when the rotating assembly transfers the sample bottle into the water injection assembly, the reciprocating motion assembly 33 will press the nozzle 32 into the sample bottle; at this time, the nozzle 32 will inject the water sample in the water tank 31 into the sample bottle, thereby completing the sampling work of the water sample; after a certain amount of water sample is injected into the sample bottle, the nozzle 32 will be pulled away from the sample bottle under the driving of the reciprocating motion assembly 33; if the nozzle 32 is not pulled away from the sample bottle, the sample bottle will be tripped by the nozzle 32 or even will bend the nozzle 32 under the driving of the conveying belt 25; therefore, the preferred water injection assembly can effectively improve the working fluency and stability of the sampling mechanism.

[0054] In a preferred embodiment of the present application, the reciprocating motion assembly 33 comprises a second rotating shaft 331, a driving bevel gear 332, a driven bevel gear 333, a cam 334, a sleeve 335 and a sliding rod 336.

[0055] The bottom of the second rotating shaft 331 is vertically installed at the center shaft of the driving disc 22; the top of the second rotating shaft 331 is coaxially fixedly installed with a driving bevel gear 332; a driven bevel gear 333 is engaged with the driving bevel gear 332; the driven bevel gear 333 is coaxially fixedly installed with a cam 334; the longest end of the cam 334 moves to the horizontal lowest point after the driven disc 24 is at the intermittent moment one second; therefore, the synchronization of the water injection assembly and the rotating assembly is completed not only through the bevel gear pair, but also the waiting time required for the nozzle 32 to descend can be adjusted by adjusting the matching angle of the longest end of the cam 334 and the driven bevel gear 333.

[0056] The sleeve 335 is vertically fixedly installed below the cam 334; a through hole is formed at the center shaft of the sleeve 335; the upper and lower ends of the slide rod 336 are symmetrically provided with discs; the sleeve 335 is sequentially installed with a spring and the upper end of the slide rod 336 from bottom to top; the lower end of the slide rod 336 penetrates through the through hole; the slide rod 336 slides up and down in the sleeve 335; the upper end of the slide rod 336 is in contact with the bottom of the cam 334; the lower end of the slide rod 336 is fixedly installed with the nozzle 32.

[0057] In the above embodiment, the second rotating shaft 331 starts to rotate under the driving of the driving disc 22; therefore, the driving bevel gear 332 drives the driven bevel gear 333 to start to rotate under the rotation of the second rotating shaft 331; since the driven bevel gear 333 is coaxially fixedly installed with the cam 334, the cam 334 rotates around the center shaft of the driven bevel gear 333; at this time, the upper end of the slide rod 336 is pressed on the lower surface of the cam 334 due to the elastic pressure of the spring, so that the slide rod 336 slides along the center shaft direction of the sleeve 335 under the rotation of the cam 334; therefore, the nozzle 32 reciprocates under the driving of the slide rod 336; and since the longest end of the cam 334 needs to reach the horizontal lowest point after the conveyor belt 25 is at the intermittent moment one second, the nozzle 32 will move downward under the driving of the cam 334 after the center shaft of the sample bottle is aligned with the center shaft of the nozzle 32 for a period of time.

[0058] In a preferred embodiment of the present application, the nozzle 32 adopts a direct current nozzle; the direct current nozzle adopts a cylindrical structure; the diameter of the nozzle 32 is 5-10 mm.

[0059] In a preferred embodiment of the present application, in order to accurately inject the water sample into the sample bottle when the conveyor belt 25 is running, the side wall of the nozzle 32 is provided with a film pressure sensor; the nozzle 32 is electrically connected with the control system; the nozzle 32 is made of plastic material; since the sealing cover of the sample bottle adopts a sports drink nozzle type, when the nozzle 32 is pushed into the sample bottle by the reciprocating motion assembly 33, the film pressure sensor attached to the side wall of the nozzle 32 is pressed by the sealing cover of the sample bottle, at this time, the control system judges the accurate time of the nozzle 32 to release the water sample according to the change of the pressure value.

[0060] In order to avoid the damage caused by the collision of the ship sailing at night, the outer wall of the shell 1 is sleeved with a reflective single-sided cloth, the surface of which is coated with a silver reflective material, and the elongation of the reflective single-sided cloth is 20-30%; when the light of the illuminating lamp on the bow deck or the moonlight at night is projected onto the reflective single-sided cloth, it will be reflected, which plays a warning role for the passing ships at night.

[0061] In a preferred embodiment of the present application, in order to realize the real-time and convenience of detecting the water source, the monitoring assembly 4 comprises a water inlet tank 41, a spectrometer and an electric gate valve; the water inlet tank 41 is fixedly connected with the bottom of the shell 1; the spectrometer is vertically fixedly installed on the top of the water inlet tank 41; one side of the water inlet tank 41 is communicated with the peristaltic pump through a pipeline; the other side of the water inlet tank 41 is communicated with the electric gate valve through a pipeline; the electric gate valve is electrically connected with the control system; and the electric gate valve is arranged underwater.

[0062] In the above embodiment, when the peristaltic pump pumps water, the control system controls the electric gate valve to open; since the electric gate valve is located underwater, water will enter the water inlet tank 41 from the electric gate valve; at this time, the water surface in the water inlet tank 41 slowly rises until the detection head of the spectrometer contacts the water sample in the water inlet tank 41, and then the spectrometer detects the conventional parameters in the water sample; after the monitoring assembly 4 completes the detection of the conventional parameters of the water sample, the peristaltic pump starts to pump the water sample out of the water inlet tank 41; and before the set sampling time every day, the control system will control the electric gate valve to open in advance, and then control the peristaltic pump to pump out the water sample; by means of the flow of the water sample, the water sample flow pipeline of the water inlet tank 41 is flushed, so as to ensure that the detection data will not be contaminated by residual pollutants.

[0063] As a preferred embodiment of the present application, in order to ensure that the water inlet of the water inlet tank 41 will not be blocked by floating objects under the river surface, such as dry branches, small fish and even plastic bags, etc., the outer part of the water inlet tank 41 is sleeved with a protective net in an annular structure; the diameter of the protective net is 350mm, and the height is 100mm; the protective net is made of SUS304 stainless steel material; therefore, when these floating objects drift in the water, they will be intercepted by the protective net first; thus, the working stability of the water inlet tank 41 is improved, and the normal operation of the system is ensured.

[0064] The second embodiment of the present application exists. In this embodiment, as a preferred embodiment of the present application, the reciprocating linear motion assembly adopts an electric push rod, the stroke of which is 50 mm, and the electric push rod is electrically connected with the control system; the moving end of the electric push rod is fixedly connected with the nozzle 32; as a preferred embodiment of the present application, the top of the shell 1 is provided with an infrared sensor, which is located directly below the nozzle 32; when the infrared rays of the infrared sensor are blocked by the sample bottle, it represents that the sample bottle is located directly below the nozzle 32; at this time, the infrared sensor transmits a signal into the control system, and then the control system controls the electric push rod to push the nozzle 32 into the sample bottle; finally, the nozzle 32 injects sample water into the sample bottle to complete sampling.
