Description

Technical Field

[0001] The invention belongs to the technical field of water quality monitoring, and in particular relates to a buoy type water pollution monitoring device. Background Art

[0002] With the increasingly stringent requirements for water protection, water quality monitoring has become a more important item in hydrological monitoring. Water quality monitoring mainly adopts buoy-type water quality monitoring equipment floating on the water body, equipped with relevant probe sensors to collect corresponding parameters, and also collects water samples. It also uses physical, chemical and biological technical means to conduct qualitative, quantitative and systematic comprehensive analysis of the pollutants and their related components, so as to explore and study the changes in water quality.

[0003] Existing water quality monitoring equipment has a single function and cannot simultaneously meet the diverse needs of water quality parameter collection and monitoring, water sample collection and analysis, self-cleaning, etc. In addition, during long-term use, the probe sensor surface immersed in the water will absorb impurities, affecting monitoring, so it needs to be cleaned regularly. Summary of the invention

[0004] In view of the above-mentioned defects of the prior art, the technical problem to be solved by the present invention is to provide a buoy-type water pollution monitoring device, which has the functions of real-time collection and monitoring of water quality parameters, water sample collection, and self-cleaning.

[0005] To achieve the above object, the present invention provides a buoy-type water pollution monitoring device, comprising:

[0006] The suspension carrier comprises a floating body sleeve, a floating body, a wind wheel, an intermediate shaft, and a plurality of photovoltaic panels; the floating body sleeve is a cylindrical structure with a cavity inside, and the floating body surrounds and is fixed to the outer wall of the floating body sleeve; the lower part of the intermediate shaft penetrates into the floating body sleeve cavity from the center of the top of the floating body sleeve, and the wind wheel sleeve is installed on the top of the intermediate shaft; a plurality of photovoltaic panels are installed above the floating body sleeve and are evenly spaced and distributed circumferentially with the intermediate shaft as the center;

[0007] The water quality monitoring unit includes a probe monitoring module and a probe self-cleaning module; the probe monitoring module includes multiple probes and an industrial computer connected to the probes, and the probes and the industrial computer are connected through a wireless module; the probe self-cleaning module includes a probe self-cleaning shaft and an arc brush; the top of the probe self-cleaning shaft is fixedly connected to the bottom of the intermediate shaft, and multiple probes are installed at the lower part of the float sleeve and are arranged at uniform intervals around the probe self-cleaning shaft; the arc brush is arranged circumferentially along the outer wall of the probe self-cleaning shaft and is tightly attached to the corresponding outer wall of the probe; the wind wheel drives the intermediate shaft to rotate, and then drives the probe self-cleaning shaft to rotate, so that the arc brush continuously brushes the outer wall of the corresponding probe;

[0008] The water quality sampling unit comprises a sampling frame and a plurality of sampling modules and a sampling pump located on the top of the sampling frame; the sampling frame is located at the lower part of the floating sleeve cavity, and each sampling module comprises a sampling shell, a first valve shell assembly, a second valve shell assembly, a first sampling tube, a second sampling tube, a third sampling tube, and a water transfer box; one end of the sampling pump is connected to the water body through a pumping pipe, and the other end is connected to the first sampling tube of the first sampling module, and the water sample enters the sampling shell from the first sampling tube through a one-way valve; after the water sample in the sampling shell is collected, the first valve shell assembly is triggered to open, so that the first sampling tube and the second sampling tube are connected, and the water sample enters the water transfer box from the second sampling tube; after the water sample in the water transfer box reaches a certain level, the second valve shell assembly is triggered to open, so that the second sampling tube and the third sampling tube are connected, and the water sample flows from the third sampling tube to the first sampling tube of the next sampling module; after all sampling modules have finished sampling, the water sample is discharged from the third sampling tube of the last group of sampling modules connected to the drain pipe.

[0009] In the above scheme, the water pollution monitoring device floats on the water body through a suspended carrier and carries a photovoltaic panel for energy storage. The water quality monitoring unit collects water quality parameters in real time through multiple probe sensors (in actual use, probes with different functions can be selected as needed, such as COD probes, water turbidity probes, PH probes, etc.), and the industrial computer is connected to the shore through a wireless module to monitor water quality parameters in real time; the probe self-cleaning module can solve the problem of probe cleaning and improve the monitoring effect. The water quality sampling unit can collect multiple groups of water samples for analysis and research using different technical means.

[0010] As a further improvement of the present invention, a draw buckle is provided on the float sleeve, so that the entire water pollution monitoring device can be stabilized on the water surface through the cooperation of the draw buckle with the rope to prevent it from floating away.

[0011] As a further improvement of the present invention, the probe self-cleaning module further includes a probe rotation reset mechanism; the probe is mounted on the sampling frame so as to be rotatable in a circular manner and not axially movable, and the probe rotation reset mechanism includes a probe cover and a coil spring; the probe cover is mounted at a position corresponding to the probe on the sampling frame, the probe cover is hollow inside, and the inner wall of the probe cover and the outer wall of the probe are respectively assembled with the two ends of the coil spring;

[0012] When the arc brush of the probe self-cleaning shaft brushes the outer wall of the probe, the probe is driven to rotate. The rotation of the probe causes the coil spring to roll up and store elastic force. At the same time, the arc brush and the outer wall of the probe also have relative rotation to achieve brushing. After the arc brush separates from the outer wall of the probe, the coil spring drives the probe to reverse and reset.

[0013] In the above scheme, the arc brush rotates with the self-cleaning shaft of the probe, brushing the side wall of the probe while driving the probe to rotate, and the probe can be reset under the action of the coil spring, so that the outer wall of the probe can be brushed as comprehensively as possible, avoiding the problem of poor effect caused by only brushing a part of the outer wall.

[0014] As a further improvement of the present invention, the first valve housing assembly includes: a piston, a piston shaft, a piston spring, a first cable, a first valve housing, a first valve core, a first valve stem, a first valve stem spring, a first lock seat, and a first lock shaft;

[0015] The piston is sealed and slidably assembled in the sampling cavity of the sampling shell, one end of the piston shaft is assembled with the piston, and the other end is sleeved with a piston spring and then passes through the sampling shell and is connected to one end of the first cable;

[0016] The first valve core is sealed and slidably assembled in the valve cavity of the first valve housing. The first valve core is provided with a valve core hole. One end of the first valve stem is assembled with the first valve core, and the other end is sleeved with the first valve stem spring and then passes through the first lock seat located at the top of the first valve housing. The first valve stem spring applies a thrust force to the first valve core away from the first lock seat.

[0017] The side wall of the first valve stem is provided with a first locking groove, one end of the first locking shaft is provided with a first sliding block, the first sliding block is provided with a first locking block, the other end of the first locking shaft is sleeved with a first locking shaft spring and then passes through the first locking seat and is assembled with the other end of the first cable.

[0018] In the above scheme, in the initial state, under the action of the first lock shaft spring, one end of the first lock block is snap-fitted into the first lock groove, so that the first valve stem cannot move away from the first lock seat under the action of the first valve stem spring and store elastic force. At this time, the first valve core hole is not connected to the second sampling tube so that the first valve core keeps isolating the first and second sampling tubes. When the water sample in the sampling shell is collected, the piston shaft rises and pulls the first cable to separate the first lock block from the first lock groove, so that the first valve stem moves away from the first lock seat under the action of the first valve stem spring, so that the first valve core hole connects the first and second collection tubes.

[0019] As a further improvement of the present invention, the second valve housing assembly includes: a water plug, a water spring, a float, a drainage pipe, a second cable, a second valve housing, a second valve core, a second valve stem, a second valve stem spring, a second lock seat, a second lock shaft, and a lever;

[0020] A floating block that can float on the water surface is installed in the water box, and the water box is provided with a water valve hole connected to the second sampling tube. The water plug is slidably and sealed in the water valve hole. The water spring is installed at the bottom of the water plug and is used to apply a pressing thrust to the water plug so that the water plug and the end surface of the water valve hole are pressed and sealed in the initial state; the drainage tube is located in the water box, one end of which is connected to the bottom end of the water valve hole, and the other end passes through the floating block and is located below the floating block; one end of the lever enters the water box and is located above the floating block, and the other end is assembled with the other end of the second cable;

[0021] The second valve core is sealed and slidably assembled with the valve cavity of the second valve housing, a valve core hole is provided on the second valve core, and the second valve core is assembled with one end of the second valve stem, the other end of the second valve stem is sleeved with the second valve stem spring and then passes through the second lock seat located at the top of the second valve housing, and the second valve stem spring applies a thrust force to the first valve core away from the second lock seat;

[0022] The side wall of the second valve stem is provided with a second locking groove, one end of the second locking shaft is provided with a second slider, the second slider is provided with a second locking block, the other end of the second locking shaft is sleeved with a second locking shaft spring and then passes through the second locking seat and is assembled with one end of the second cable.

[0023] In the above scheme, in the initial state, under the action of the second lock shaft spring, one end of the second lock block is snap-fitted into the second lock groove, so that the second valve stem cannot move away from the second lock seat under the action of the second valve stem spring and store elastic force. At this time, the second valve core hole is not connected to the second sampling tube so that the second valve core keeps isolating the second and third sampling tubes. When the first and second collection tubes are connected, the water sample squeezes through the water plug and enters the bottom of the float in the water box through the drainage tube. The float rises and lifts one end of the lever, and the other end of the lever pulls the second cable to separate the second lock block from the second lock groove, so that the second valve stem moves away from the second lock seat under the action of the second valve stem spring, so that the second valve core hole connects the second and third collection tubes, so that the water sample enters the next collection module.

[0024] As a further improvement of the present invention, an upper limit ring cooperating with the piston is provided in the sampling cavity of the sampling shell, and a piston ring groove is provided on the side wall of the piston; a lock shell is installed on the side wall of the sampling shell, the lock shell is hollow inside and a slip ring is slidably installed, the slip ring is fixed on the insertion rod, and the insertion rod is provided with an insertion rod spring in the part between the slip ring and the closed end inside the lock shell, and the insertion rod spring applies an elastic force to push the insertion rod toward the sampling cavity, so as to keep the plug-in end of the insertion rod in the sampling cavity in the initial state, and the other end of the insertion rod passes through the lock shell;

[0025] When the piston moves toward the upper limit ring, the piston will push the rod until the piston ring groove is aligned with the plug-in end. The rod slides toward the piston ring groove under the push of the rod spring, so that the plug-in end is inserted into the piston ring groove to make the piston relatively fixed, thereby keeping the sampling space in the sampling shell unchanged.

[0026] As a further improvement of the present invention, a photovoltaic panel self-cleaning module is also provided, including: photovoltaic bristles, a brush shell, a brush frame, and a brush shaft cylinder; the top surface of the photovoltaic panel is in close contact with the photovoltaic bristles, the photovoltaic bristles are mounted on the brush shell, the brush shell is mounted on the brush frame, and the brush frame is mounted and fixed on the brush shaft cylinder; the brush shaft cylinder is non-circularly rotatable and axially slidable outside the transmission sleeve, and the transmission sleeve is circumferentially rotatable and axially slidable outside the intermediate shaft.

[0027] The wind wheel driving disk is installed after the top end of the transmission sleeve passes through the brushing shaft cylinder, and the wind wheel driving disk is directly opposite to the wind wheel friction disk and can be pressed for transmission. The wind wheel friction disk is arranged on one end of the wind wheel sleeve, and the wind wheel sleeve is fixed outside the intermediate shaft, and the wind wheel is fixed outside the wind wheel sleeve; in the initial state, the wind wheel driving disk and the wind wheel friction disk are not in contact; an axis shifting cylinder is fixed on the end of the transmission sleeve away from the wind wheel, and a cleaning driving disk and a cleaning friction disk are respectively arranged on the ends of the axis shifting cylinder and the brushing shaft cylinder close to each other, and the cleaning driving disk can be pressed against the cleaning friction disk to drive the cleaning friction disk to rotate; in the initial state, the cleaning driving disk and the cleaning friction disk are not in contact.

[0028] The shaft shifting cylinder is equipped with a telescopic device, which drives the shaft shifting cylinder to axially extend and retract, so that the wind wheel driving disk and the wind wheel friction disk are compressed and transmitted, and the cleaning driving disk and the cleaning friction disk are compressed and transmitted. At this time, the rotation of the wind wheel can drive the transmission sleeve and the brush shaft cylinder to rotate, so that the photovoltaic brush bristles can clean the surface of the photovoltaic panel while rotating.

[0029] The shaft shifting cylinder is sleeved with a driving cylinder, which cannot rotate relatively in a circle but can slide axially outside the shaft shifting cylinder, and is driven to rotate by a motor; the telescopic device drives the shaft shifting cylinder to telescope axially, so that the wind wheel driving disk and the wind wheel friction disk are pressed and transmitted, and the cleaning driving disk and the cleaning friction disk are pressed and transmitted, and the motor-driven cylinder rotates, driving the transmission sleeve and the brush shaft cylinder to rotate, so that the photovoltaic brush bristles clean the surface of the photovoltaic panel while rotating.

[0030] In the above scheme, under the premise that the telescopic device drives the shaft shifting cylinder to axially telescope, and the wind wheel driving disk and the wind wheel friction disk are pressed and transmitted, and the cleaning driving disk and the cleaning friction disk are pressed and transmitted, not only can the photovoltaic brush brush the photovoltaic panel by rotating the wind wheel, but also the photovoltaic brush brush the photovoltaic panel by driving the driving cylinder driven by the motor.

[0031] As a further improvement of the present invention, the brush rack is fixed on the brush shaft cylinder through a brush sleeve; the brush sleeve is provided with a brush sleeve ring cavity inside, the brush sleeve ring cavity is connected with the brush cavity of the brush shell, and a plurality of penetrating brush holes are provided on one side of the brush shell where the photovoltaic brush bristles are installed; the brush sleeve ring cavity is connected with the water supply shell through a water pipe, and a pumping shell connected with the water supply shell is provided below the water supply shell, and the pumping shell is connected to the water body through the water pipe. One end of the brush shaft cylinder is installed in the pumping shell, and the part of the brush shaft cylinder located in the pumping shell is provided with an impeller, and when the brush shaft cylinder rotates, negative pressure can be generated in the pumping shell to pump the water body to the water supply shell, and after passing through the brush sleeve ring cavity and the brush cavity of the brush shell, the water flows out from the brush holes to cooperate with the photovoltaic brush bristles to brush the photovoltaic panel.

[0032] As a further improvement of the present invention, a generator is arranged in the floating sleeve, and the end of the intermediate shaft away from the wind wheel passes through the transmission sleeve and then passes through the generator. The intermediate shaft is assembled and fixed with the power generation input shaft of the generator. When the intermediate shaft rotates, it drives the power generation input shaft to work to generate wind power. The electricity generated by the generator and the photovoltaic panel is input into the battery for storage, and the battery is installed in the floating sleeve.

[0033] The beneficial effects of the present invention are as follows:

[0034] 1. The water pollution monitoring device floats on the water body through a suspended carrier, and collects water quality parameters in real time through multiple probe sensors. The industrial computer communicates with the shore through a wireless module to monitor water quality parameters in real time; the probe self-cleaning module can solve the cleaning problem of the probe and improve the monitoring effect; the water quality sampling unit can collect multiple groups of water samples for analysis and research using different technical means.

[0035] 2. The present invention can also use photovoltaic power generation and wind power generation to effectively increase power generation, thereby meeting the needs of actual use and providing more convenience for water quality monitoring.

[0036] 3. The present invention adopts the rotation of the brush shell to brush the photovoltaic panel, which can effectively remove the debris on the photovoltaic panel, thereby effectively ensuring the power generation efficiency of the photovoltaic panel, and the brush shell can be driven by a wind wheel or a motor, thereby effectively meeting the actual use requirements.

[0037] 4. While brushing the photovoltaic panels, the outer wall of the probe can also be brushed with an arc brush, thereby effectively improving the life and detection accuracy of the probe, meeting the needs of long-term use, and improving the effect of water quality monitoring.

[0038] 5. The present invention also adds a water quality sampling function. Multiple samplings can be achieved by connecting multiple sampling modules in series. After each sampling is completed, the residual water in the previous pipeline is discharged through the water box to greatly reduce the interference of the previously sampled water on subsequent sampling, thereby improving the credibility of the sampled samples, and can be used for water quality monitoring of key water areas.

DETAILED DESCRIPTION

[0067] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0068] See also Figure 1-Figure 13 The buoy-type water pollution monitoring device of this embodiment includes a float 210, a float cover 110, an inner cover 120, and a wind wheel 220. The float cover 110 is fixed outside the inner cover 120, and the float 210 is fixed outside the float cover 110. The float 210 is made of low-density material to have a large buoyancy. When in use, the buoyancy of the float 210 is used to make the entire device float on the water surface. A buckle 111 is provided on the float cover 110. When in use, the buckle 111 can be assembled with a rope, so that the entire water pollution monitoring device can be floated and fixed on the water surface by the rope to prevent it from drifting away.

[0069] The inner sleeve 120 is provided with a first inner sleeve plate 121, a first partition plate 141, a second partition plate 142, a third partition plate 143, a second inner sleeve plate 122, and an inner sleeve ring 123 from top to bottom. A bracket 231 is provided on the first inner sleeve plate 121, and a photovoltaic panel 230 is provided on the bracket 231. The surface of the photovoltaic panel 230 can be closely attached to the photovoltaic bristles 252 so that the photovoltaic bristles 252 can brush the surface of the photovoltaic panel 230 when the photovoltaic bristles 252 rotate. The photovoltaic bristles 252 are provided on the brushing shell 250. The brush shell 250 is installed on the brush frame 240, and a brush sleeve 241 is provided on the brush frame 240. The brush sleeve 241 is installed and fixed on the brush shaft cylinder 340, and a brush sleeve ring cavity 2411 is provided inside the brush sleeve 241. The brush sleeve ring cavity 2411 is connected with the inside of the brush cavity 251 through the plug-in tube 253. The brush cavity 251 is arranged in the brush shell 250 and a plurality of penetrating brush holes (not marked) are provided on one side of the brush shell 250 where the photovoltaic bristles 252 are installed.

[0070] The scrubbing collar cavity 2411 is connected to the water supply cavity 461 of the water supply shell 460 through the first water inlet pipe 471, the water supply cavity 461 is connected to the water pumping cavity 451 of the water pumping shell 450, the water pumping cavity 451 is connected to the plug-in connector 474 through the second water inlet pipe 472, the plug-in connector 474 is connected to one end of the third water inlet pipe 473, and a filter 4731 is installed on the other end of the third water inlet pipe 473, and the filter 4731 is immersed in the water.

[0071] The bottom end of the scrubbing shaft cylinder 340 passes through the water supply chamber and the water pumping chamber, and an impeller 452 is installed on the outer wall of the scrubbing shaft cylinder located in the water pumping chamber 451. When the scrubbing shaft cylinder 340 rotates, it can generate negative pressure in the water pumping chamber 451, thereby generating suction negative pressure on one end of the second water inlet pipe 472 and pushing pressure on one end of the water supply chamber 461, so that it acts as a water pump, which can pump water at one end of the filter 4731 to the water pumping chamber 451, and then press it into the first water supply chamber 461 from the water pumping chamber 451. The water in the water supply chamber 461 is input into the scrubbing ring chamber 2411 through the first water inlet pipe 471, and then input into the scrubbing chamber 251 from the plug-in tube 253, and finally flows out from the scrubbing hole to cooperate with the photovoltaic brush bristles 252 to scrub the photovoltaic panel 230. For the specific structure inside the pumping shell 450 and the impeller 452, the relevant design of the existing water pump can be adopted. In theory, it is only necessary to pump water into the pumping chamber 451 and press the water into the first water inlet pipe 471. In practice, the existing water pump can be used to remove the motor part and use the brush shaft cylinder 340 to drive it.

[0072] The water supply shell 460 is installed on the water pumping shell 450, and the water pumping shell 450 is installed on the first partition plate 141. The scrubbing shaft cylinder 340 passes through the water supply shell 460 and the water pumping shell 450. The scrubbing shaft cylinder 340 and the water supply shell 460 and / or the water pumping shell 450 can rotate relative to each other in a circular manner but cannot be axially moved.

[0073] The brushing shaft cylinder 340 is sleeved outside the transmission sleeve 330 in a non-circumferentially rotatable and axially slidable manner. The transmission sleeve 330 is sleeved outside the intermediate shaft 310 in a circumferentially rotatable and axially slidable manner. The top end of the transmission sleeve 330 passes through the brushing shaft cylinder 340 and is installed with a wind wheel driving disk 331. The wind wheel driving disk 331 is directly opposite to the wind wheel friction disk 321 and can be pressed and driven. The wind wheel friction disk 321 is set on the bottom end of the wind wheel sleeve 320. The wind wheel sleeve 320 is sleeved and fixed outside the intermediate shaft 310, and the wind wheel 220 is sleeved and fixed outside the wind wheel sleeve 320. The wind wheel 220 can be rotated by wind. Figure 6 In the initial state, the wind wheel driving disk 331 is not in contact with the wind wheel friction disk 321, and at this time, the wind wheel 220 cannot drive the transmission sleeve 330 to rotate.

[0074] The end of the transmission sleeve 330 away from the wind wheel 220 is fixed with a shaft shifting cylinder 350, and the ends of the shaft shifting cylinder 350 and the brushing shaft cylinder 340 close to each other are respectively provided with a cleaning drive disk 351 and a cleaning friction disk 341. The cleaning drive disk 351 can be pressed against the cleaning friction disk 341 to drive the cleaning friction disk 341 to rotate, that is, drive the brushing shaft cylinder 340 to rotate. Figure 6 In the initial state, the cleaning drive disc 351 is not in contact with the cleaning friction disc 341, and at this time, the shaft shifting cylinder 350 cannot drive the brushing shaft cylinder 340 to rotate.

[0075] The shaft shifting cylinder 350 is sheathed with a driving cylinder 360, which is installed on the second partition plate 142 and the third partition plate 143 so as to be rotatable in a circular manner but not axially movable. The driving cylinder 360 is sheathed outside the shaft shifting cylinder 350 so as to be non-rotatable in a relatively circular manner but axially slidable. The driving cylinder 360 is connected to the motor shaft 421 through a belt 260 to form a belt transmission mechanism, and one end of the motor shaft 421 is installed in the motor 420, which is installed on the third partition plate 143.

[0076] The second partition plate 142 is also provided with a telescopic device 430, which is mounted outside the shaft shifting tube 350 and cannot be relatively axially moved with the shaft shifting tube 350 but can be assembled in a circular rotation. In this embodiment, the telescopic device can be selected with a hollow electromagnet or an electromagnetic coil. When a hollow electromagnet is selected, the hollow telescopic shaft and the shaft shifting tube 350 cannot be relatively axially moved but can be assembled in a circular rotation. When in use, the shaft shifting tube 350 can be driven to move by directly driving the hollow telescopic shaft through the hollow electromagnet. When the telescopic device is selected with an electromagnetic coil, and a magnet is installed on the shaft shifting tube 350, when in use, the telescopic device 430 is energized to generate a magnetic field, and the magnetic field drives the shaft shifting tube 350 to move axially. The telescopic device 430 can also use an existing telescopic electromagnet, except that the two ends of its telescopic shaft are respectively assembled and fixed with the intermediate shaft 310 (the intermediate shaft 310 can be regarded as divided into two sections at the telescopic electromagnet), and its telescopic shaft and the telescopic electromagnet can be assembled in a circular rotation. Of course, in theory, the telescopic device 430 only needs to be able to be assembled with the shaft shifting cylinder 350 so as to be non-axially movable and rotatable in a circular manner, and at the same time be able to drive the shaft shifting cylinder 350 to move axially.

[0077] The shaft shifting cylinder 350 is driven by the telescopic device to move the backward wind wheel upward, the wind wheel driving disc 331 and the wind wheel friction disc 321 are pressed and transmitted, and the cleaning driving disc 351 is pressed and transmitted with the cleaning friction disc 341 after moving upward. At this time, the wind wheel 220 can rotate to drive the transmission sleeve 330 and the shaft shifting cylinder 350 to rotate, and can also drive the brushing shaft cylinder 340 to rotate, so that the first water inlet pipe 471 supplies water to the brushing chamber 251 and rotates the brushing frame 240 to clean the photovoltaic panel 230. At this time, the motor 420 can also be started, and the motor drives the driving cylinder 360 to rotate, and the driving cylinder 360 drives the shaft shifting cylinder 350 and the transmission sleeve 330 to rotate synchronously, and the shaft shifting cylinder 350 and the transmission sleeve 330 respectively drive the wind wheel 220 and the brushing shaft cylinder 340 to rotate, so as to realize the brushing of the photovoltaic panel 230. The motor 420 does not have a brake function. After power failure, the motor shaft 421 can be driven to rotate by the drive cylinder 360 through the belt, so that the wind wheel can drive the brush shaft cylinder 340 and the transmission sleeve 330 to rotate.

[0078] The end of the intermediate shaft 310 away from the wind wheel 220 passes through the transmission sleeve 330 and then passes through the generator 410 and the second inner sleeve plate 122. The intermediate shaft 310 is fixedly assembled with the generator 410's power input shaft and can rotate in a circular manner but cannot move axially with the second inner sleeve plate 122. The power input shaft of the generator 410 adopts a hollow shaft with a through hole in the middle. When the intermediate shaft 310 rotates, it can drive the power input shaft of the generator 410 to rotate, so that the generator generates electricity. In this embodiment, an ordinary generator can also be used, but the two ends of its power input shaft respectively pass through the outer shell of the generator and are respectively assembled and fixed with the intermediate shaft 310 (the intermediate shaft 310 can be regarded as divided into two sections at the generator 410).

[0079] A sampling rack 130 is also installed in the inner sleeve 120. One end of the sampling rack 130 is tightly attached to the inner sleeve ring 123 and fixed to the inner sleeve ring 123 by bolts. A probe 440 for detecting water quality is installed on the sampling rack 130. There are multiple probes 440. In actual use, probes with different functions can be selected according to needs, such as COD probe, water quality turbidity probe, PH probe, etc. The sampling rack 130 can also be rotatable in the circle and cannot be axially moved. The probe self-cleaning shaft 370 and the intermediate shaft 310 are respectively provided with a driven disk 371 and a driving disk 311 on the end close to each other. The driven disk 371 and the driving disk 311 are pressed and driven so that the intermediate shaft 310 can drive the probe self-cleaning shaft 370 to rotate when it rotates. A support part 131 is provided on the sampling rack 130. The support part 131 is used to contact the ground when operating on the shore to support the entire device, and at the same time protect the probe sensor inside it.

[0080] A plurality of probes 440 are evenly installed in the circumferential direction of the probe self-cleaning shaft 370 with the probe self-cleaning shaft 370 as the center, and arc brushes 270 are installed at the corresponding positions of the probe self-cleaning shaft 370 and the probe 440, that is, the arc brushes are arranged along the circumference of the probe self-cleaning shaft, and the probe bristles 271 on the arc brush 270 are only distributed on a part of the circumference of the arc brush 270, and the probe bristles 271 are in close contact with the probe 440. When the probe self-cleaning shaft 370 rotates, the arc brush 270 is driven to rotate, and when the arc brush 270 rotates, the probe bristles 271 are driven to rotate, and the probe bristles 271 continuously brush the outer wall of the probe 440, thereby brushing the outer wall of the probe.

[0081] Combination Figure 14-17In some embodiments, the probe 440 is installed on the sampling frame 130 so that it can rotate in a circular manner but cannot move axially. A probe cover 490 is installed at the corresponding position of the sampling frame 130 and the probe 440. The interior of the probe cover 490 is hollow. The inner wall of the probe cover 490 and the outer wall of the probe 440 are respectively assembled with the two ends of the coil spring 491. A stop protrusion 492 is also provided on the inner wall of the probe cover 490, and a matching protrusion 442 is also provided on the outer wall of the probe 440. The matching protrusion 442 cannot pass through the stop protrusion 492 to limit the rotation angle of the probe 440 and prevent the probe from excessive rotation. The signal of the probe 440 is connected to the industrial computer through the wire 441.

[0082] When the probe bristles 271 are brushing the outer wall of the probe 440, the probe 440 can be driven to rotate. When the probe 440 rotates, the coil spring 491 is rolled up to store elastic force. At the same time, the probe bristles 271 and the outer wall of the probe 440 can also rotate relative to each other to achieve brushing. After the probe bristles 271 are separated from the outer wall of the probe 440, the coil spring drives the probe 440 to reverse until the next time the probe bristles 271 and the outer wall of the probe 440 brush, and so on and so forth. In this way, the outer wall of the probe 440 can be brushed as comprehensively as possible to avoid the problem of poor effect caused by only brushing a part of the outer wall.

[0083] The inner sleeve 120 is equipped with a battery and a corresponding charging and discharging circuit, a wireless module, and an industrial computer. The electricity generated by the generator and the photovoltaic panel is processed by the charging and discharging circuit and then input into the battery for storage. The electricity of the battery can power each module. The industrial computer communicates with the wireless module, and the wireless module is connected to the network wirelessly so that the relevant data obtained by the industrial computer can be remotely controlled, such as the battery power, the data detected by the corresponding sensors of each probe, the number of sampling times, etc. The wireless module can select a 5G module. Of course, these are all existing technologies, and existing technologies with remote control functions, photovoltaic power generation and generator power generation can be directly adopted, such as existing water quality detection equipment and monitoring equipment that can be remotely connected to the network.

[0084] See also Figure 1-Figure 27 In actual use, in order to further verify and study the needs, sampling is required. Currently, sampling is mainly done manually, which is obviously too time-consuming and labor-intensive. In addition, manual sampling is not feasible for some sampling requirements after certain parameters are set. In this regard, the present application adds a sampling module 500 for sampling. Specifically:

[0085] A plurality of sampling modules 500 and a sampling pump 480 are installed on the sampling rack 130. The sampling module 500 is used to store sampled water. The inlet of the sampling pump 480 is connected to one end of a water pumping pipe 481, and the other end of the water pumping pipe 481 enters the water after passing through the sampling rack 130. The outlet of the sampling pump 480 is connected to the first sampling pipe 530 of the sampling module 500 close thereto through a water pipe, and two adjacent sampling modules 500 are connected through a connecting pipe 475. Specifically, the third sampling pipe 550 of the previous sampling module 500 is connected to the first sampling pipe 530 of the next sampling module 500 through the connecting pipe 475, and the third sampling pipe 550 of the last sampling module 500 is connected to the sampling rack 130 or is directly open.

[0086] A drain pipe 401 is also installed on the sampling rack 130, and a one-way valve 402 is installed on one end of the drain pipe 401 close to the water body. The one-way valve 402 is elastic and keeps the drain pipe 401 closed by self-generated elastic force, so that water in the water body cannot pass through the drain pipe 401 and enter the inner sleeve and the inner side of the sampling rack 130. When there is water in the sampling rack 130, the water will enter the drain pipe 401, and then the one-way valve 402 will be opened by gravity, so that the water will be discharged.

[0087] See Figure 14-Figure 27 The sampling module 500 includes a sampling shell 510 and two valve shells 520 (the first valve shell and the second valve shell have similar structures). The sampling shell 510 has a hollow sampling cavity 511 inside, and the sampling shell 510 is also provided with a stop groove 514 and a sampling jack 515. The sampling jack 515 is plugged and assembled with a first sampling convex tube 531. The first sampling convex tube 531 is installed on the first sampling tube 530. The first sampling tube 530 is installed on the pipe rack 501 and the first sampling tube 530 is connected to the valve cavity 521 of the valve shell 520 adjacent thereto. The sampling box 510 is installed on the pipe rack 501.

[0088] A one-way valve plate 620 is installed in the stop groove 514. One end of the one-way valve plate 620 is assembled with the inner wall of the stop groove 514, and the other end is an open end. The one-way valve plate 620 is elastic. In the initial state, the one-way valve plate is pressed and sealed with the end surface of the stop groove 514 by self-generated elastic force, thereby sealing and dividing the sampling cavity 511 and the sampling jack 515. When the water pressure of the first sampling convex pipe 531 is sufficient to push open the one-way valve plate 620, the water flow pushes open the one-way valve plate 620, thereby inputting water into the sampling cavity 511 for storage.

[0089] An upper limit ring 513 and a lower limit ring 512 are also provided in the sampling chamber 511. The portion of the sampling chamber 511 between the upper limit ring 513 and the lower limit ring 512 is sealed and slidably assembled with the piston 610. The piston 610 is provided with a piston ring groove 611. The piston 610 is assembled with one end of the piston shaft 810. The other end of the piston shaft 810 is fitted with a piston spring 710, passes through the sampling shell 510, and is assembled with the connecting cap 751. Fig. 22 As shown, it is an enlarged view of part C of the first valve housing, the connecting cap 751 is assembled with one end of the first cable 750, and the other end of the first cable 750 passes through the two first guide wheels 701 and is assembled and fixed with the first locking shaft 840. The two first guide wheels 701 are rotatably mounted on the first guide wheel plate 583, and the first guide wheel plate 583 is mounted on the corresponding first valve housing 520.

[0090] like Fig.21 As shown, the two valve housings 520 have hollow valve chambers 521 inside, and the two valve chambers 521 are connected through the second sampling tube 540. The second sampling tube 540 is provided with a second convex tube 541, and the second convex tube 541 is connected to the inside of the water box 570; the valve chamber 521 of the second valve housing 520 away from the sampling housing 510 is connected to one end of the third sampling tube 550. The first and second valve housings have the same internal structure. Taking the second valve housing as an example, the second valve chamber 521 is sealed and slidably assembled with the second valve core 560, the second valve core 560 is provided with a second valve core hole 561, and the second valve core is assembled with one end of the second valve stem 820, and the other end of the second valve stem 820 is sleeved with the second valve stem spring 720, passes through the second lock seat 580, and is assembled with the elastic band 830, and the second valve stem spring 720 applies a thrust to the second valve core away from the second lock seat 580, and the second lock seat 580 is installed on the second valve housing 520.

[0091] The first valve stem locking structure is as follows Fig. 22 As shown, the first valve stem 820 is provided with a first locking groove 821. In the initial state, the first locking groove 821 is engaged with one end of the first locking block 842 so that the first valve stem 820 cannot move away from the first lock seat 580 under the action of the first valve stem spring 720 and store elastic force. At this time, the first valve core hole 561 is not connected with the second sampling tube 540 so that the first valve core 560 is maintained and the first and second sampling tubes 540 are separated. The first locking block 842 is installed on the first slider 841, and the first slider 841 is installed on one end of the first lock shaft 840. The other end of the first lock shaft 840 is covered with the first lock shaft spring 650, passes through the first lock shaft hole 582, and is assembled with the first cable 750. The first slider 841 is engaged with the first slider groove 581 and slidably assembled. The first lock shaft hole 582 and the first slider groove 581 are both provided on the first lock seat 580. Fig.24 It is the locking structure of the second valve stem, which is the same as the locking structure of the first valve stem.

[0092] The interior of the water box 570 is a hollow water chamber 571 with an open top. The top of the water chamber 571 is closed by a water cover 574. The water cover 574 is installed on the water box 570. A water plug 572 and a water valve hole 573 are also provided on the water cover 574. The water plug 572, the water valve hole 573 and the water chamber 571 are connected in sequence. The water plug 572 is plugged and assembled with the second convex pipe 541. A water plug 640 is slidably and sealedly installed in the water valve hole 573. A water spring 730 is installed between the water plug 640 and the end of the water valve hole 573 away from the water plug 572. The water spring 730 is used to apply a thrust to the water plug 640 to press the water plug 572 so that the end surface of the water plug 640 and the water valve hole 573 are pressed and sealed in the initial state.

[0093] The water-passing cover 574 is located at one end of the water-passing valve hole 573 and is assembled with one end of the drainage pipe 852. The second valve housing 520 corresponding to the water-passing box 570 is assembled with one end of the return pipe 851. The drainage pipe 852 and the return pipe 851 are both axially slidably mounted with a floating block 630, and the floating block 630 can float on the water surface. The drainage pipe and the return pipe can provide guidance for the floating block, and the return pipe provides an exhaust space for the downward movement of the second valve core 560. The portion of the return pipe 851 below the floating block 630 ( Fig.23 A return pipe groove 8511 is provided on the Fig.21 The other end of the drainage pipe 852 and the other end of the return pipe 851 are both located below the floating block 630.

[0094] The water box 570 is also provided with an axis plate 575, which is hinged to the middle part of the lever 770 through a hinge shaft 771. One end of the lever 770 enters the water box 570 and is located above the floating block 630. The other end of the lever 770 is assembled with one end of the cable shaft 761. The cable shaft 761 is assembled with one end of the second cable 760. The second cable 760 passes around the corresponding guide wheel 701 and is assembled with the corresponding lock shaft 840 (see Fig.24 The end of the lever 770 assembled with the cable shaft 761 is also pressed against one end of the spring sheet 650, and the other end of the spring sheet 650 is assembled with the water box 570. The spring sheet 650 is elastic and exerts an elastic force on the end of the lever 770 located on the cable shaft 761 to prevent it from rotating downward (see Fig.23 ).

[0095] See also Figure 25-26In some embodiments, a lock shell 860 is also installed on the sampling shell 510. The interior of the lock shell 860 is hollow and a slip ring 871 is slidably installed. The slip ring 871 is fixed on the insertion rod 870. The insertion rod 870 is located between the slip ring 871 and the closed end inside the lock shell 860. The insertion rod spring 660 applies an elastic force to the insertion rod 870 to push the sampling cavity 511 to keep the plug end 873 of the insertion rod 870 in the sampling cavity 511 in the initial state, and the other end of the insertion rod 870 passes through the lock shell 860 and is assembled with the pull ring 872. When the piston 610 moves toward the upper limit ring 513 to reach its position, the piston 610 will push the rod 870 until the piston ring groove 611 is aligned with the plug-in end 873. Pushed by the rod spring 660, the rod 870 slides toward the piston ring groove 611 so that the plug-in end 873 is inserted into the piston ring groove 611 to make the piston 610 relatively fixed, thereby keeping the sampling space in the sampling chamber 511 unchanged.

[0096] In some embodiments, a through groove 5711 is provided at the bottom of the water flow box 570, and the cross-sectional area of ​​the through groove 5711 does not exceed 1 / 4 of the internal cross-sectional area of ​​the second convex tube 541. This design can enable the water flow of the second convex tube 541 to quickly enter the water flow chamber 571 and cause the floating block 630 to float. However, after the water of the second convex tube 541 enters the water flow chamber 571, the water will be discharged to the sampling rack 130 through the through groove 5711, and then discharged through the drain pipe 401. The floating block 630 moves down and resets under the action of gravity.

[0097] See also Fig.21 When sampling is required, the industrial computer controls the sampling pump 480 to start, and the sampling pump 480 pumps water into the first sampling tube 530 connected thereto through the pumping pipe 481. The water flows from the first sampling tube 530 and the first convex tube 531 into the corresponding sampling shell 510 and opens the one-way valve plate 620. The water flows into the sampling cavity 511. The water pushes the piston to squeeze the piston spring 710 upward through the water pressure. At the same time, the piston is made of a material that can float on water so that the piston has buoyancy to assist in squeezing the piston spring 710 until the piston is tightly attached to the upper limit ring 513. At this time, the plug-in end 873 is inserted into the piston ring groove 611 to lock the piston 610, thereby completing the sampling. During this process, the piston rod 810 moves upward, thereby driving the first cable 750 upward until the first cable 750 is gradually tightened and then applies a pulling force to the corresponding first lock shaft 840 to move outward, thereby pulling the first lock shaft 840 to move outward so that the first locking block 842 exits the corresponding first locking groove 821. The first valve stem 820 loses its restraint and drives the corresponding first valve core 560 downward under the push of the first valve stem spring 720 until the valve core hole 561 connects the first sampling tube 530 and the second sampling tube 540. At this time, the corresponding other valve core 560 (on the right) remains stationary, completing a sampling.

[0098] During the secondary sampling, the sampling pump 480 is started to pump water to the second sampling tube 540. Since the second valve core on the right side blocks the water from entering the third sampling tube and the piston in the left sampling shell cannot move, the water pressure enters the second convex tube 541. The water pressure pushes the water plug 640 open so that the water passes through the water valve hole 573 and enters the drainage tube 852 and finally enters the bottom of the float 630. The float 630 floats upward until the float is pressed against one end of the lever 770, and as the float 630 moves upward, it pushes the lever 770 to install. One end of the cable shaft 761 overcomes the force of the spring sheet and rotates downward, thereby generating a pulling force and displacement on the second cable 760. The second cable 760 pulls the corresponding second lock shaft 840 to move so that the corresponding second lock block 842 exits the corresponding second lock groove 821. The second valve stem and the second valve core on the right side move downward under the action of the second valve stem spring 720, so that the second valve core hole 561 connects the second sampling tube 540 and the third sampling tube 550, and the water enters the next sampling chamber 511 to complete the sampling. The water in the pipeline is discharged through the through groove of the water box 570 to avoid interfering with the second sampling, thereby reducing the probability of the second sampling sample being contaminated.

[0099] When it is necessary to remove the sampling shell 510, remove the sampling rack 130, then disassemble the connecting cap 751, and then pull the sampling shell 510 out of the pipe rack 501, and then push open the one-way valve plate 620, and pull the plug rod 870 out of the piston ring groove 611 to discharge the sampled water. Then reinstall the sampling shell 510, pull the part of the elastic band 830 between the two valve shells 520 upward, so as to pull the two valve stems 820 to reset (the corresponding locking block and the locking groove are engaged and assembled), and the elastic band 830 is elastic, so that the two valve stems can be stretched and retracted by elastic force to achieve self-adaptation when they move separately, but when the elastic band 830 is manually pulled, the elastic band can effectively pull the valve stems on both sides to move after reaching the extension limit, so as to achieve the rapid reset of the two valve stems. After the two valve stems are reset, the lever is reset under the action of the spring sheet, and if the floating block is not reset under gravity, it will be pressed down by the lever to meet the need for re-sampling.
