Description

Technical Field

[0001] The present invention relates to the technical field of water quality monitoring, and in particular to a water quality monitoring device and a monitoring method thereof. Background Art

[0002] Water quality monitoring mainly monitors the quality of water bodies, and is used to reflect the comprehensive indicators of water quality conditions. Generally, the temperature, color, turbidity, pH value, conductivity, suspended matter, dissolved oxygen, chemical oxygen demand and biochemical oxygen demand of water samples are collected for comprehensive judgment. When monitoring a large area of ​​water, the water quality conditions at different locations will be different, so it is necessary to monitor different locations of the water body and conduct a comprehensive evaluation.

[0003] The Chinese patent with the authorization announcement number CN221802970U discloses a cruise-type water quality monitoring station, including a floating platform, an equipment layer, a counterweight layer and a drive layer are arranged below the floating platform, an automatic winding drum is arranged in the equipment layer, a cable is wound in the automatic winding drum, the cable passes through the bottom wall of the equipment layer and is connected to a first sensor, a counterweight block is arranged at the lower end of the first sensor, and a drive mechanism is arranged in the drive layer. The entire monitoring station is driven to move to different positions in the water area by the drive layer, and when collecting data, the automatic winding drum is controlled to rotate, the cable is released, and the first sensor at the end of the cable is lowered.

[0004] The shortcomings of the above-mentioned prior art solutions are: although the above-mentioned solution can be moved in the water area and monitor the water quality at different positions by retracting and releasing the cable, the first sensor is not effectively cleaned after the first sensor for collecting water quality data is retracted by reeling in the cable each time. After the sensor contacts the water source, especially in the presence of polluted water, impurities and pollutants in the water are easily attached to the surface of the sensor probe. Therefore, when the position is changed for monitoring, the accuracy and reliability of the monitoring results will be greatly affected. In addition, the sensor directly sinks into the water for monitoring, which is easily damaged by floating objects. Summary of the invention

[0023] Beneficial effects of the present invention:

[0024] 1. The water quality monitoring device adopted in the present invention can float on the water surface by means of a buoyancy mechanism, and can be driven by a driving paddle to move in the water area, so as to facilitate monitoring of water quality at different positions, and can monitor a variety of water quality data by means of a multi-parameter sensor group. During each monitoring, the installation tube on which the multi-parameter sensor group is installed is first lowered and immersed in the water. After the monitoring is completed, the installation tube is controlled to rise. During the rising process of the installation tube, the swing tube arranged at the bottom thereof alternately squeezes the fixed baffles longitudinally staggeredly distributed on both sides by means of the unidirectional movable baffles arranged on both sides, so as to realize the reciprocating swing of the swing tube. The swinging swing tube relies on a linkage mechanism to make the top plate rotate and squeeze the piston block in the piston liquid feeding cylinder, so as to realize the cleaning liquid to flush the multi-parameter sensor group through the nozzle, and at the same time, the soft brush is also linked to move up and down to wipe the sensor to realize cleaning, so as to reduce the influence on the accuracy of the next water quality data collection.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] like Figure 1-Figure 7As shown, a water quality monitoring device can be remotely controlled and moved on the water surface, which is convenient for water quality monitoring at different locations of a wide range of water sources, including a support plate 1, a buoyancy mechanism and a driving paddle 6. The buoyancy mechanism is arranged below the support plate 1, and the buoyancy mechanism is used to float on the water surface, thereby supporting the support plate 1. The driving paddle 6 is installed on one side of the buoyancy mechanism. The driving paddle 6 includes a steering drive motor and a propulsion drive motor. The propulsion drive motor is used to drive the paddle 6 to rotate and generate propulsion force. The two are integrated. The steering drive motor is used to adjust the angle of the integrated propulsion drive motor and the driving paddle 6, thereby adjusting the monitoring device to turn on the water surface; the device also includes a multi-parameter lifting water quality detection mechanism and a self-cleaning mechanism. The multi-parameter lifting water quality monitoring mechanism includes a multi-parameter sensor group 22 and a swinging filtering mechanism for protecting the multi-parameter sensor group 22. The multi-parameter sensor group 22 includes a pH value acquisition The data processing unit 5 is used to collect and store different data collected by the multi-parameter sensor group 22, and can be remotely transmitted to the control terminal. At the same time, the data processing unit 5 also includes a remote command receiving module and a control module, which is convenient for receiving the control command sent by the terminal, and then controlling the driving paddle 6 to drive and operate. At the same time, the multi-parameter lifting water quality monitoring mechanism can also be controlled to lift and lower, which is convenient for water quality monitoring; the swing-type filtering mechanism is used to filter larger garbage and debris in the water to prevent the multi-parameter sensor group 22 from being damaged by impact; during the lifting process of the multi-parameter lifting water quality monitoring mechanism, the swing-type filtering mechanism swings back and forth to facilitate the removal of attached garbage and debris;

[0038] The self-cleaning mechanism includes a flushing mechanism and a linkage mechanism. The flushing mechanism is used to flush and clean the multi-parameter sensor group 22. The linkage mechanism is arranged between the flushing mechanism and the swinging filter mechanism. During the reciprocating swinging process of the swinging filter mechanism, the linkage mechanism drives the flushing mechanism to clean the multi-parameter sensor group 22.

[0039] In some specific embodiments, in combination Figures 2 to 4 As shown, the multi-parameter lifting water quality monitoring mechanism also includes an electric telescopic rod 4 and a mounting tube 7. The electric telescopic rod 4 is fixedly connected to the support plate 1, and the telescopic end of the electric telescopic rod 4 is vertically downward. It is best to set two electric telescopic rods 4. The telescopic end of the electric telescopic rod 4 is fixedly connected to the lifting horizontal plate 8. The mounting tube 7 is fixedly set at the bottom of the lifting horizontal plate 8, and the multi-parameter sensor group 22 is circumferentially distributed on the inner side of the mounting tube 7 near the top, and exists by being embedded in the inner wall of the mounting tube 7. The cable passes upward to the location of the data processing unit 5, and the cable retains a certain length to ensure the lifting and lowering movement of the multi-parameter sensor group 22; the swing-type filtering mechanism is arranged below the mounting tube 7, and the self-cleaning mechanism is arranged above the mounting tube 7.

[0040] When water quality monitoring is required, the electric telescopic rod 4 is started to extend downward, and the electric telescopic rod 4 drives the installation tube 7 to descend through the lifting horizontal plate 8 until the installation tube 7 is immersed in water. The multi-parameter sensor group 22 distributed in this way is in contact with the water, which is convenient for collecting different data through different types of sensors, and one side of the probe of the multi-parameter sensor group 22 is distributed on the inner side of the installation tube 7, which can be effectively protected.

[0041] In some specific embodiments, in combination Figure 2 and Figure 4 As shown, the swing-type filtering mechanism includes a swing cylinder 16, a connecting shaft 25, a filter element 20 and an alternating extrusion structure. The swing cylinder 16 is arranged below the mounting cylinder 7. An elastic corrugated sleeve 17 is connected between the top of the swing cylinder 16 and the mounting cylinder 7. The elastic corrugated sleeve 17 is a rubber body that can be bent and deformed. Hangers 24 are fixedly connected to both sides of the bottom of the mounting cylinder 7. The swing cylinder 16 is rotatably connected to the hanger 24 through the connecting shaft 25. The relative positions of the swing cylinder 16 and the connecting shaft 25 are fixed. The connecting shaft 25 can rotate around its own axis relative to the hanger 24. The filter element 20 is fixedly arranged at the bottom of the swing cylinder 16, and the alternating extrusion structure is cooperatively arranged on the outside of the swing cylinder 16.

[0042] Among them, the alternating extrusion mechanism includes a one-way movable baffle 21, a vertical plate 9 and a fixed baffle 11. There are two one-way movable baffles 21, which are distributed on both sides of the swing cylinder 16. One side of each one-way movable baffle 21 is movably connected to the swing cylinder 16 through a rebound hinge. It should be noted that the rebound hinge is installed at the upper position of the connection side of the one-way movable baffle 21, and the end face of the connection side of the one-way movable baffle 21 is in contact with the outer wall of the swing cylinder 16, so that the one-way movable baffle 21 can be deflected unidirectionally upward from the horizontal position and can return to the horizontal position, but cannot be deflected downward from the horizontal position; there are two vertical plates 9, which are distributed on both sides of the swing cylinder 16. The vertical plates 9 are fixedly connected to the support plate 1, and each vertical plate 9 is longitudinally equidistantly distributed with multiple fixed baffles 11 that cooperate with the one-way movable baffle 21, and the one-way movable baffles 21 distributed on the two vertical plates 9 are longitudinally staggered, not laterally aligned.

[0043] During the process of the installation tube 7 with the multi-parameter sensor group 22 being lowered and immersed in the water, since the one-way movable baffle 21 can be deflected upward from the horizontal position relative to the swing tube 16, during the descending process, the swing tube 16 and the one-way movable baffles 21 on both sides squeeze through the fixed baffles 11 distributed on both sides, and only the one-way movable baffle 21 is deflected, and the swing tube 16 is not deflected. When the installation tube 7 needs to be raised with the multi-parameter sensor group 22, at this time, since the one-way movable baffle 21 cannot be deflected downward from the horizontal position relative to the swing tube 16, when the one-way movable baffle 21 contacts and squeezes the fixed baffle 11 during the lifting process, it will drive the swing tube 16 to move. Since the fixed baffles 11 distributed longitudinally on both sides are longitudinally misaligned, each time the one-way movable baffle 21 on one side of the swing tube 16 squeezes and contacts the corresponding fixed baffle 11, due to the unilateral squeezing effect, the swing tube 16 will rely on the connecting shaft 25 to deflect to one side. Figure 7 As shown, during this process, the elastic bellows sleeve 17 is deformed to generate a rebound force. When the contacting one-way movable baffle 21 is separated from the corresponding fixed baffle 11, the pendulum tube 16 swings back by relying on its own weight and the rebound force of the elastic bellows sleeve 17, and then continues to rise. The one-way movable baffle 21 on the other side of the pendulum tube 16 is squeezed by the corresponding fixed baffle 11, and this process is repeated, and the pendulum tube 16 realizes reciprocating swing.

[0044] It should be noted that the filter element 20 is a spherical structure with filter holes evenly distributed on the spherical structure. The filter element 20 facilitates water to pass through and contact the multi-parameter sensor group 22, while preventing large floating objects in the water from passing through and colliding with the multi-parameter sensor group 22, thereby achieving protection. Moreover, the spherical structure facilitates the removal of attached floating objects or debris that penetrate into the filter holes during the reciprocating swing of the pendulum tube 16, while also facilitating the rapid outflow of water entering the pendulum tube 16 and the mounting tube 7.

[0045] In some specific embodiments, elastic metal frames 18 are fixedly connected to both sides of the swing cylinder 16, and an impact ball 19 is fixedly connected to the top of the elastic metal frame 18. The mounting cylinder 7 is a cylinder made of elastic metal. During the swinging process of the swing cylinder 16, the elastic metal frame 18 on one side moves away from the mounting cylinder 7, and the elastic metal frame 18 on the other side bends and deforms to generate a rebound force. When the swing is reset, the elastic metal frame 18 that is away rebounds and hits the mounting cylinder 7 through the impact ball 19, thereby causing the mounting cylinder 7 to vibrate. The vibration is transmitted to the multi-parameter sensor group 22, which facilitates the shaking off of attached impurities and further improves the cleaning effect.

[0046] In some specific embodiments, such as Figures 4 to 6As shown, the flushing mechanism includes a linkage shaft 12, a piston liquid-feeding cylinder 14 and an annular brush member. The linkage shaft 12 is rotatably arranged on the lifting horizontal plate 8. Specifically, a support block is vertically welded on the lifting horizontal plate 8, and the linkage shaft 12 passes through the support block horizontally and is rotatably connected to the support block through a bearing; one end of the linkage shaft 12 is connected to the connecting shaft 25 through a linkage mechanism, and the other end of the linkage shaft 12 is fixedly connected to a top plate 13, and two top plates 13 are symmetrically arranged. The bottom of the piston liquid-feeding cylinder 14 is fixedly connected to an output slide pipe 15, and the output The bottom of the slide tube 15 passes through the lifting horizontal plate 8 and extends to the inside of the mounting tube 7. The output slide tube 15 can slide longitudinally relative to the lifting horizontal plate 8 with the piston liquid delivery tube 14. A first supporting spring 30 is connected between the output slide tube 15 and the lifting horizontal plate 8. An annular spray brush integrated part for cleaning the multi-parameter sensor group 22 is also connected to the bottom of the output slide tube 15. The initial height of the annular spray brush integrated part is higher than the position of the multi-parameter sensor group 22. The piston liquid delivery tube 14 is slidably connected to the piston block 27. The piston block 27 and the A second support spring 28 is connected between the bottom of the piston liquid delivery cylinder 14. The specification of the second support spring 28 is smaller than that of the first support spring 30. Under the same force conditions, the second support spring 28 is deformed before the first support spring 30. The top plate 13 is used to cooperate with the extrusion piston block 27. A limit block 29 that cooperates with the piston block 27 is fixedly connected to the inner wall of the piston liquid delivery cylinder 14. A clean water tank 37 is installed on the lifting horizontal plate 8. The clean water tank 37 stores distilled water for cleaning the multi-parameter sensor group 22. Or clean water, a one-way infusion valve component 31 is connected between the bottom of the cleaning water tank 37 and the bottom of the piston liquid feeding cylinder 14, the one-way infusion valve component 31 includes a hose and a one-way valve, the hose is connected to the cleaning water tank 37 and the piston liquid feeding cylinder 14, the one-way valve is used to allow the cleaning liquid to flow only from the cleaning water tank 37 to the piston liquid feeding cylinder 14, and cannot flow in the opposite direction; a one-way liquid outlet valve 32 is installed on the output slide pipe 15, the one-way liquid outlet valve 32 can only allow the liquid to flow from the inside of the piston liquid feeding cylinder 14 to the annular spray brush integrated part, and cannot flow in the opposite direction.

[0047] Among them, the annular spray brush integrated part includes an annular frame 33, a soft brush 34 and a nozzle 35. The annular frame 33 is fixedly arranged at the bottom of the output slide pipe 15, and the soft brush 34 is circumferentially distributed on the outer circle of the annular frame 33. When the annular frame 33 rises and falls with the output slide pipe 15, the soft brush 34 can wipe the multi-parameter sensor group 22. There are multiple nozzles 35, which are circumferentially distributed at the bottom of the annular frame 33. Each nozzle 35 corresponds to flushing a sensor or collector of the multi-parameter sensor group 22. When the annular frame 33 is in the initial position, the distributed nozzles 35 are just facing the multi-parameter sensor group 22; each nozzle 35 is connected to the bottom of the output slide pipe 15 through the tube body, and the tube body diameter between the nozzle 35 and the output slide pipe 15 is relatively thin to prevent the liquid in the piston liquid delivery cylinder 14 from flowing out at will.

[0048] In addition, the linkage mechanism includes a transmission wheel 23 and a transmission belt 26 . The transmission wheel 23 is coaxially fixedly connected to the connecting shaft 25 and the linkage shaft 12 , and the two transmission wheels 23 are connected by the transmission belt 26 .

[0049] During the reciprocating swing of the pendulum cylinder 16, the connecting shaft 25 continuously rotates forward and reversely. During this process, the connecting shaft 25 drives the linkage shaft 12 to rotate synchronously through the transmission wheel 23 and the transmission belt 26. During the forward and reverse rotation, the linkage shaft 12 squeezes the piston block 27 through the top plate 13 on one side. Since the specification of the second support spring 28 is smaller than that of the first support spring 30, under the same force conditions, the second support spring 28 deforms before the first support spring 30, and the piston block 27 slides downward relative to the piston liquid feeding cylinder 14. During this process, the internal cleaning liquid is squeezed and output through the output slide pipe 15, and then sprayed out through each nozzle 35 to flush the distributed multi-parameter sensor group 22. In this process, the second support spring 28 is compressed and deformed, and the first support spring 30 has not yet deformed. When the piston block 27 drops to the position of the limit block 29 and cannot continue to drop, the top plate 13 continues to deflect and pushes the piston block 27 downward. At this time, the piston block 27 is blocked by the limit block 29, which will drive the entire piston liquid feeding cylinder 14 to descend, and the piston liquid feeding cylinder 14 will drive the output slide tube 15 to slide downward, and the output slide tube 15 will drive the annular frame 33 to descend, and the annular frame 33 will descend with the distributed soft brushes 34, so as to facilitate the brushing of the multi-parameter sensor group 22, and to facilitate the cleaning of the used multi-parameter sensor group 22 to a certain extent each time, so as to reduce the impact on the next monitoring result, and in the process of the output slide tube 15 descending, the first support spring 30 is stretched to generate a rebound force, and when the top plate 13 is reset, the piston block 27 is reset by the second support spring 28, so as to facilitate the suction of cleaning liquid from the cleaning water tank 37 for replenishment through the one-way infusion valve 31, and at the same time, the output slide tube 15 is lifted and reset by the rebound force of the first support spring 30, and this is repeated, so as to facilitate the cleaning of the multi-parameter sensor group 22 for multiple times in the process of the lifting cross plate 8 and the swing cylinder 16 rising.

[0050] In some specific embodiments, a V-shaped baffle plate 3 is fixedly connected to one side of the support plate 1 away from the driving paddle 6. The V-shaped baffle plate 3 is located on the forward side of the entire device to facilitate pushing away floating objects in the water during the forward process.

[0051] In some specific embodiments, such as Figure 2As shown, the buoyancy mechanism includes a float plate 2 and a floating airbag 10. The float plate 2 is fixedly connected to the bottom of the support plate 1 through a bracket. The float plate 2 is made of buoyancy material. The floating airbag 10 is fixedly arranged at the bottom of the float plate 2. The floating airbag 10 and the float plate 2 cooperate to facilitate the entire device to float on the water surface, while preventing the raised installation tube 7 and the multi-parameter sensor group 22 from contacting the water. In order to ensure that the installation tube 7 can be raised and lowered to contact the water, a hole 36 is opened on the float plate 2.

[0052] A monitoring method for a water quality monitoring device, the specific steps are as follows:

[0053] The first step is to first make the entire water quality monitoring device float on the water surface by relying on the buoyancy mechanism, and then control the driving paddle 6 to operate, driving the entire water quality monitoring device to move to different positions on the water surface;

[0054] Step 2: Control the multi-parameter lifting water quality monitoring mechanism to descend, so that the multi-parameter sensor group 22 descends and is immersed in the water. The multi-parameter sensor group 22 collects multiple values ​​of water quality. During the collection process, the swing filter mechanism protects the multi-parameter sensor group 22.

[0055] Step 3: After the data collection at one location is completed, the multi-parameter lifting water quality monitoring mechanism is controlled to rise; during the lifting process of the multi-parameter lifting water quality monitoring mechanism, the swing filter mechanism swings back and forth to throw off the attached garbage and debris;

[0056] Step 4: During the reciprocating swing of the swing filter mechanism, the swing filter mechanism drives the flushing mechanism to clean the multi-parameter sensor group 22 through the linkage mechanism, thereby reducing the impact on the next water quality monitoring result.

[0057] In order to facilitate the understanding of the embodiments of this solution by those skilled in the art, the working principle of the water quality monitoring device of this solution is briefly described in combination with specific application scenarios:

[0058] When water quality monitoring is required, the electric telescopic rod 4 is started to extend downward, and the electric telescopic rod 4 drives the installation tube 7 to descend through the lifting horizontal plate 8 until the installation tube 7 is immersed in the water, so that the multi-parameter sensor group 22 distributed in this way is in contact with the water, which is convenient for collecting different data through different types of sensors; and the swing tube 16 and the filter 20 are used to filter the water contacting the multi-parameter sensor group 22 to prevent floating debris from damaging the sensor;

[0059] When the acquisition of a position data is completed, the electric telescopic rod 4 is controlled to retract, and the installation tube 7 and the distributed multi-parameter sensor group 22 are driven to rise through the lifting cross plate 8. It should be noted that in the process of the installation tube 7 with the multi-parameter sensor group 22 descending and being immersed in the water, since the one-way movable baffle 21 can deflect upward from the horizontal position relative to the swing tube 16, during the descent process, the swing tube 16 squeezes through the fixed baffles 11 distributed on both sides with the one-way movable baffles 21 on both sides, and only the one-way movable baffle 21 is deflected, and the swing tube 16 is not deflected. When the installation tube 7 needs to be lifted with the multi-parameter sensor group 22, at this time, since the one-way movable baffle 21 cannot deflect downward from the horizontal position relative to the swing tube 16, when the one-way movable baffle 21 contacts and squeezes the fixed baffle 11 during the lifting process, it will drive the swing tube 16 to move. The distributed fixed baffles 11 are longitudinally misaligned. Each time, only the one-way movable baffle 21 on one side of the swing cylinder 16 squeezes and contacts the corresponding fixed baffle 11. Due to the one-sided squeezing effect, the swing cylinder 16 will deflect to one side relying on the connecting shaft 25. During this process, the elastic bellows sleeve 17 deforms and generates a rebound force. When the contacting one-way movable baffle 21 is separated from the corresponding fixed baffle 11, the swing cylinder 16 relies on its own weight and the rebound force of the elastic bellows sleeve 17 to swing back, and then continues to rise. The one-way movable baffle 21 on the other side of the swing cylinder 16 is squeezed by the corresponding fixed baffle 11. This is repeated, and the swing cylinder 16 realizes reciprocating swing. During the reciprocating swing of the swing cylinder 16, it is convenient to throw out the attached floating objects or debris that penetrates the filter holes. At the same time, it is also convenient to accelerate the rapid outflow of water entering the swing cylinder 16 and the installation cylinder 7, so as to quickly monitor the water quality at the next position.

[0060] During the reciprocating swing of the pendulum cylinder 16, the connecting shaft 25 continuously rotates forward and reversely. During this process, the connecting shaft 25 drives the linkage shaft 12 to rotate synchronously through the transmission wheel 23 and the transmission belt 26. During the forward and reverse rotation, the linkage shaft 12 squeezes the piston block 27 through the top plate 13 on one side. Since the specification of the second support spring 28 is smaller than that of the first support spring 30, under the same force conditions, the second support spring 28 deforms before the first support spring 30, and the piston block 27 slides downward relative to the piston liquid feeding cylinder 14. During this process, the internal cleaning liquid is squeezed and output through the output slide pipe 15, and then sprayed out through each nozzle 35 to flush the distributed multi-parameter sensor group 22. In this process, the second support spring 28 is compressed and deformed, and the first support spring 30 has not yet deformed. When the piston block 27 drops to the position of the limit block 29 and cannot continue to drop, the top plate 13 continues to deflect and pushes the piston block 27 downward. At this time, the piston block 27 is blocked by the limit block 29, and the piston liquid feeding cylinder 14 will drive the entire piston liquid feeding cylinder 14 to descend, and the piston liquid feeding cylinder 14 will drive the output slide tube 15 to slide downward, and the output slide tube 15 will drive the annular frame 33 to descend, and the annular frame 33 will descend with the distributed soft brushes 34, so as to facilitate the brushing of the multi-parameter sensor group 22, and to facilitate the cleaning of the used multi-parameter sensor group 22 to a certain extent each time, so as to reduce the influence on the next monitoring result, and in the process of the output slide tube 15 descending, the first support spring 30 is stretched to generate a rebound force, and when the top plate 13 is reset, the piston block 27 is reset by the second support spring 28, so as to facilitate the suction of cleaning liquid from the cleaning water tank 37 for replenishment through the one-way infusion valve member 31, and at the same time, the output slide tube 15 is lifted and reset by the rebound force of the first support spring 30, and this is repeated, so as to facilitate the cleaning of the multi-parameter sensor group 22 for multiple times in the process of the lifting cross plate 8 and the swing cylinder 16 rising.

[0061] Several embodiments of the present invention are described in detail above, but the embodiments of the present invention are not limited thereto and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
