Description

Technical Field

[0001] The present invention belongs to the technical field of water quality monitoring, and specifically is a smart water monitoring device based on multimodal data fusion. Background Art

[0002] Water monitoring refers to the real-time monitoring and evaluation of water quality, water volume, water flow, etc. through various means and methods to ensure the rational use of water resources, the health of the water environment and the safety of human water use. The main contents of water monitoring include water quality monitoring, water volume monitoring and water flow monitoring; among them, water quality monitoring includes physical indicators (such as temperature, color, etc.), chemical indicators (such as pH value, heavy metals, etc.) and biological indicators (such as bacteria, viruses, etc.); water volume monitoring includes water level and flow data of water bodies (such as rivers, lakes, etc.); water flow monitoring includes water flow speed and flow direction data.

[0003] Therefore, in the prior art, water monitoring usually uses various sensors and fixed-point monitoring devices to collect data. Existing fixed-point monitoring devices often need to sample and analyze water bodies. Under the interference of external interference (such as water flow impact disturbance, liquid surface water level changes that cannot be detected), water sample factors (impurities, suspended matter, etc. in the water body are in long-term contact with the sensor), etc., it is easy to cause inaccurate water quality data measurement. Summary of the invention

[0004] The purpose of the present invention is to provide a smart water monitoring device based on multimodal data fusion, so as to reduce the interference of impurities in the water body on water quality monitoring data and improve the monitoring accuracy.

[0005] In order to achieve the above object, the technical solution of the present invention is as follows:

[0006] A smart water monitoring device based on multimodal data fusion includes a floating block, a plurality of guide plates are fixedly connected to the bottom of the floating block, a plurality of water pipes are arranged on the guide plates, a detection cavity is opened in the floating block, and a plurality of water quality sensors for detecting water quality monitoring data are arranged in the detection cavity; one end of the water pipe is connected to the detection cavity, and a filter is arranged at the other end of the water pipe;

[0007] A driving mechanism for actively or passively forming water flow changes is provided at the center of the floating block. The driving mechanism includes a second fan blade fixedly connected to the central axis that rotates with the floating block. The second fan blade is located between adjacent guide plates. A peristaltic pump for pumping water in the water pipe is provided on the central axis. A one-way valve is connected to the top of the detection chamber, and the one-way valve is used to connect the detection chamber with the outside world.

[0008] A reversing mechanism for switching the rotation direction of the second fan blade and a sinking mechanism for controlling the up and down movement of the floating block are provided above the central axis;

[0009] A controller is also provided in the floating block, and the controller is electrically connected to the reversing mechanism, the water quality sensor and the settling mechanism;

[0010] The controller is used to record and store the water quality monitoring data of each water quality sensor, and at the same time, based on the timing control instruction, the reversing mechanism is controlled to drive the second fan blade to rotate in the opposite direction.

[0011] The following beneficial effects are achieved by adopting the above scheme:

[0012] When the external water flow drives the second fan blade to rotate counterclockwise, the impurities in the sample entering the detection chamber are filtered through the filter, thereby ensuring that the water quality sensor is free of attachment interference during use, so as to facilitate subsequent detection by the water quality sensor.

[0013] When the controller receives an external signal, it controls the reversing mechanism to make the second blade rotate clockwise, so that the peristaltic pump on the central axis reverses the pumping of water inside the detection chamber to clean the water pipe again, thereby realizing multimodal data fusion control through water quality monitoring data, external water flow change monitoring and timing instructions, so as to reduce impurities that may remain attached to the water pipe, ensure the purity of the sample during subsequent sampling and testing, thereby reducing the interference of impurities in the water body on the water quality monitoring data and improving the monitoring accuracy.

[0014] Furthermore, a rotating shaft is fixedly connected to one side of the filter screen, and the rotating shaft is rotatably matched with the guide plate; a placement groove is also opened on the guide plate, and the placement groove is connected to the water pipe;

[0015] When the second fan blade rotates counterclockwise, the filter screen is located in the placement groove, and when the second fan blade rotates clockwise, the filter screen is located outside the placement groove.

[0016] Beneficial effects: When the second fan blade rotates counterclockwise, the filter is shielded by placing the groove so that the filter can stably filter impurities; when the second fan blade rotates clockwise, the water flow generated by the second fan blade and the water pipe will push the filter to rotate around the rotating axis through the water flow accumulated in the detection chamber, so as to achieve reverse cleaning of impurities attached to the filter.

[0017] Furthermore, the rotating shaft and the guide plate are slidably matched, and a flow regulating mechanism for controlling the internal diameter of the water pipe is also provided on the water pipe;

[0018] The flow regulating mechanism includes a second communication hole connected with the water pipe, a second top block is slidably matched on the water pipe, the second top block is vertically arranged with the second communication hole, a first communication hole corresponding to the second communication hole is opened on the second top block, a second spring is fixedly connected to one end of the second top block, and the first top block is abutted against the other end of the second top block;

[0019] One end of the first top block close to the second top block is conical, one end of the first top block away from the second top block is fixedly connected to the rotating shaft, and a first spring is provided between the end of the first top block away from the second top block and the guide plate; when the first top block moves to the highest point, the first top block and the second top block abut against each other, and the first connecting hole and the second connecting hole are blocked; when the first top block moves to the lowest point, the first top block and the second top block are separated, and the first connecting hole and the second connecting hole are connected.

[0020] Beneficial effect: The flow rate of the detection chamber through the water pipe can be adjusted by moving the rotating shaft as a whole, so as to adjust the flushing volume of each water pipe according to the amount of impurities that may be adsorbed by each water pipe, reduce the blockage of the water pipe caused by impurities attached to the water pipe, and reduce the mixing of water quality in different areas, resulting in inaccurate water quality monitoring data.

[0021] Furthermore, the sedimentation mechanism includes a liquid inlet tank and a water storage tank located above the detection chamber, the liquid inlet tank is arranged circumferentially with the floating block as the center; a pressure plate is slidably matched in the liquid inlet tank, and a spring is provided between the pressure plate and the floating block;

[0022] A water level monitoring sensor for detecting changes in the liquid level of the water tank is provided in the water tank, a liquid inlet pipe is connected between the liquid inlet tank and the water tank, a liquid outlet pipe is connected to the bottom of the water tank, and the liquid outlet pipe is also connected to a first solenoid valve, and the first solenoid valve and the water level monitoring sensor are electrically connected to the controller;

[0023] When the pressure plate moves to the farthest point, the outside world is connected to the water storage tank through the liquid inlet pipe.

[0024] Beneficial effects: The changes in water flow disturbance caused by external weather changes have a great impact on the fluctuation of the floating block. The flow changes of the external water flow drive the pressure plate to move. When the pressure plate moves to the position of the liquid inlet pipe, the external water flow enters the water storage tank to control the floating block to sink underwater, so as to reduce the interference of the large degree of water surface fluctuation on the device, to protect the stability of the device in bad weather, and to reduce the probability of collision damage caused by water flow disturbance.

[0025] Furthermore, the top of the floating block is concave, and the top of the floating block is rotatably matched with a first fan blade, and the top of the water storage tank is also connected to a plurality of air intake pipes, the air intake pipes are arranged circumferentially with the first fan blade as the center, and the air intake pipes are connected to a second solenoid valve, and the second solenoid valve is electrically connected to the controller;

[0026] The reversing mechanism comprises a double-headed motor, the input end of the first blade is coaxially connected to the double-headed motor, the output end of the double-headed motor is also connected to the first gear, the first gear is sleeved with a gear ring, and the gear ring is meshed with the first gear;

[0027] The top of the central shaft is fixedly connected with a second gear; a pushing block is sleeved on the gear ring, and the pushing block and the gear ring are slidably matched; and an elastic layer is fixedly connected to the bottom of the water storage tank, and the elastic layer is fixedly connected to the pushing block; when the pushing block moves to the lowest point, the gear ring is meshed with the second gear and the first gear.

[0028] Beneficial effect: With the increase of water accumulation inside the water tank, the gear ring is driven to move by the push block, and the first fan blade and the second fan blade are connected and rotated by the engagement of the gear ring with the first gear and the second gear, thereby facilitating the cleaning of the filter. At the same time, the second solenoid valve is controlled to facilitate the air intake of the water tank to ensure the discharge of the water accumulated inside the water tank.

[0029] Further, the guide plate is in a shuttle shape, and the tip of the guide plate is circumferentially arranged along the counterclockwise rotation direction.

[0030] Beneficial effect: by guiding the external water flow through the shuttle-shaped guide plate, the external water flow can easily push the first fan blade to rotate in the counterclockwise direction, so that the filter can filter the external water flow, reduce the starting of the double-head motor and save energy.

[0031] Furthermore, the peristaltic pump includes a shell, a water pipe is provided on the inner wall of the shell, and a plurality of extrusion wheels are rotatably arranged in the shell. A bracket is provided between the extrusion wheel and the central axis, one end of the bracket is fixedly connected to the central axis, and the other end of the bracket is rotatably arranged with the extrusion wheel.

[0032] Beneficial effects: First, the one-way valve is used to restrict the water flow inside the detection chamber, and the extrusion wheel on the bracket is driven by the central axis to squeeze the water pipe, so as to pump the water flow inside the water pipe to the detection chamber or discharge it from the detection chamber.

[0033] Furthermore, the controller also includes a signal transmission module used for communicating between the controller and the outside world.

[0034] Beneficial effect: External control instructions are obtained through the signal transmission module to control the switching mechanism and the sedimentation mechanism to work, so as to upload and save the water quality monitoring data detected by the water quality sensor.

[0035] Furthermore, the controller also includes a timing module for recording current time change data, comparing the time change data with a set standard value, and sending a start instruction to the reversing mechanism if the time change data is greater than the standard value; if the time change data is less than the standard value, sending a maintenance instruction to the water quality sensor.

[0036] Beneficial effect: By sending the start command and the maintenance command, the second fan blade is operated periodically to achieve cleaning and filtering of the filter.

[0037] Furthermore, a pad is provided between the pressure plate and the spring, the diameter of the pad is smaller than the diameter of the pressure plate, and the pad is slidably matched with the floating block, one end of the spring is fixedly connected to the pad, and the other end of the spring is fixedly connected to the floating block.

[0038] Beneficial effect: The pad block and the two sides of the pressure plate are restricted to ensure that the pressure plate is in a horizontal moving state during the movement, and the space formed between the pressure plate and the pad block can reduce the obstruction caused by the air pressure change when the pressure plate is squeezed.

[0053] A reversing mechanism for switching the rotation direction of the second blade 4 and a settling mechanism for controlling the up and down movement of the floating block 1 are provided above the central shaft 43 .

[0054] The sedimentation mechanism includes a liquid inlet tank 3 and a water storage tank 7 located above the detection chamber 41. The liquid inlet tank 3 is arranged circumferentially with the floating block 1 as the center. A pressure plate 31 is slidably matched in the liquid inlet tank 3. A spring 32 is arranged between the pressure plate 31 and the floating block 1. A cushion block is arranged between the pressure plate 31 and the spring 32. The diameter of the cushion block is smaller than the diameter of the pressure plate 31, and the cushion block is slidably matched with the floating block 1.

When the pressure plate 31 moves to the farthest point, the outside is connected to the water storage tank 7 through the liquid inlet pipe 71.

[0055] The top of the floating block 1 is concave, and the top of the floating block 1 is rotatably matched with the first fan blade 2, the first fan blade 2 is located in the concave floating block 1, and a plurality of air intake pipes 72 are also connected to the top of the water storage tank 7, the air intake pipes 72 are circumferentially arranged with the first fan blade 2 as the center, and the air intake pipes 72 are connected to the second solenoid valve; the reversing mechanism includes a double-headed motor 21, the input end of the first fan blade 2 is coaxially connected to the double-headed motor 21, and the output end of the double-headed motor 21 is also connected to the first gear 62, the first gear 62 is sleeved with a gear ring 6, and the gear ring 6 is meshed with the first gear 62; a second gear is welded on the top of the central shaft 43; a push block 61 is sleeved on the gear ring 6, and the push block 61 is slidably matched with the gear ring 6; and an elastic layer is welded on the bottom of the water storage tank 7, and the elastic layer is bonded to the push block 61; when the push block 61 moves to the lowest point, the gear ring 6 is meshed with the second gear and the first gear 62.

[0056] A controller and a battery (both shown in the figure) are also provided in the floating block 1, and the controller is electrically connected to the double-headed motor 21, the water quality sensor, the first solenoid valve, the second solenoid valve and the water level monitoring sensor.

[0057] The controller is used to record and store the water quality monitoring data of each water quality sensor, and at the same time, based on the timing control instruction, the reversing mechanism is controlled to drive the second fan blade 4 to rotate in the opposite direction. The controller also includes a signal transmission module for the controller to communicate with the outside world and a timing module for recording the current time change data. The controller also compares the time change data with the set standard value. If the time change data is greater than the standard value, a start instruction is sent to the reversing mechanism. If the time change data is less than the standard value, a maintenance instruction is sent to the water quality sensor.

[0058] The specific implementation process is as follows: artificially place the device on the water surface, such as lakes, rivers and other water environments that need to be detected. During the flow of water, the water will enter between adjacent guide plates 11. When the external water flow drives the second fan blade 4 to rotate counterclockwise, the filter 51 is blocked by the placement groove, so that the filter 51 can stably filter impurities. At this time, the gas inside the detection chamber 41 is connected to the external water body through the restriction of the one-way valve 44, which is convenient for the continuous water inflow inside the water pipe 5. The squeezing wheel on the bracket 431 is driven by the central axis 43 to continuously squeeze the water pipe 5, so as to realize the water flow inside the pumped water pipe 5 to be transported to the detection chamber 41, so that the water quality sensor detects the water quality monitoring data of the sampled sample. Compared with the traditional method that requires electricity or additional water, it realizes the automatic collection of the sampled sample, utilizes natural resources, reduces energy consumption, prolongs the use time of the device, and responds to the green environmental protection policy.

[0059] At the same time, during the continuous operation of the device, because it is unattended, the device is prone to move with the surface of the water body with large wind and waves, thereby violently expanding with the floating devices on both sides of the river or on the water surface and causing damage (due to the impact force caused by the device driven by the fluctuation of the water surface). The fluctuation of the water surface is measured by the pressure plate 31. When the pressure plate 31 moves to the position of the liquid inlet pipe 71, the external water flows into the water storage tank 7. The controller obtains the external control instruction through the water level monitoring sensor and the signal transmission module to control the first solenoid valve or the second solenoid valve to work, and the first solenoid valve is activated to stabilize the maintenance of the liquid inside the water storage tank 7, and the second solenoid valve is activated to control the external gas to enter the water storage tank 7 to ensure that the device floats on the water surface; and then the floating block 1 is sunk underwater to reduce the interference of the large degree of water surface fluctuation caused by external weather changes on the device, so as to protect the stability of the device in bad weather and reduce the probability of collision damage caused by water flow disturbance, thereby ensuring that the device continuously monitors the water quality of the water environment.

[0060] As the amount of water inside the water tank 7 continues to increase, the ring gear 6 is engaged with the first gear 62 and the second gear through the push block 61 to achieve the connection and rotation of the first fan blade 2 and the second fan blade 4. The controller controls the double-headed motor 21 to drive the second fan blade 4 to rotate clockwise based on time changes.

[0061] During the clockwise rotation of the second blade 4, the water flow generated by the second blade 4 and the water pipe 5 pushes the filter 51 to rotate around the rotating shaft 52 with the water flow accumulated in the detection chamber 41, so as to reversely clean the impurities attached to the filter 51. At the same time, the extrusion wheel on the bracket 431 is driven by the central shaft 43 to continuously squeeze the water pipe 5 in the reverse direction, so as to pump the water flow inside the water pipe 5 out of the detection chamber 41, so that the water flow inside the detection chamber 41 can clean the water pipe 5 again. The multi-modal data fusion control of water quality monitoring data, external water flow change monitoring and timing instructions is realized to reduce the impurities that may remain attached to the water pipe 5, ensure the purity of the sample during subsequent sampling and testing, thereby reducing the interference of impurities in the water body on the water quality monitoring data and improving the monitoring accuracy. Compared with the traditional direct backwashing with water flow, the rotation of the second fan blade 4 not only reversely cleans the impurities attached to the external filter 51, but also flushes the water flow inside the water pipe 5, which not only reduces the cleaning inside the water pipe 5, but also stirs and cleans the filter 51 through the formation of opposite water flow, so as to strengthen the separation of impurities attached to the filter 51 and ensure the purity of the sample during subsequent sampling and testing.

[0062] Example 2

[0063] The difference from the above embodiment is that the rotating shaft 52 is slidably matched with the guide plate 11, and the water pipe 5 is also provided with a flow regulating mechanism for controlling the internal diameter of the water pipe 5;

[0064] The flow regulating mechanism includes a second communication hole 542 connected with the water pipe 5, and a second top block 54 is slidably matched on the water pipe 5. The second top block 54 is vertically arranged with the second communication hole 542. The second top block 54 is provided with a first communication hole 541 corresponding to the second communication hole 542. One end of the second top block 54 is fixedly connected with the second spring 32, and the other end of the second top block 54 is abutted against the first top block 53.

[0065] One end of the first top block 53 close to the second top block 54 is conical, and one end of the first top block 53 away from the second top block 54 is fixedly connected to the rotating shaft 52, and a first spring 32 is provided between the end of the first top block 53 away from the second top block 54 and the guide plate 11; when the first top block 53 moves to the highest point, the first top block 53 and the second top block 54 are abutted against each other, and the first connecting hole 541 and the second connecting hole 542 are blocked; when the first top block 53 moves to the lowest point, the first top block 53 and the second top block 54 are separated, and the first connecting hole 541 and the second connecting hole 542 are connected.

[0066] The specific implementation process is as follows: due to the increase in the weight of impurities attached to the filter 51, the rotating shaft 52 moves downward as a whole to loosen the support of the first top block 53 on the second top block 54, so that the first connecting hole 541 on the second top block 54 is connected to the second connecting hole 542, thereby adjusting the flow rate of the detection chamber 41 through the water pipe 5, and then through the fusion of multimodal data in the water quality monitoring process, the flushing volume of each water pipe 5 is adjusted according to the amount of impurities that may be adsorbed by each water pipe 5, thereby reducing the blockage of the water pipe 5 caused by impurities attached to the water pipe 5, and the occurrence of inaccurate water quality monitoring data due to the mixing of water quality in different areas.

[0067] The above is only an embodiment of the present invention, and the common knowledge such as the known specific structure and / or characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
