[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0033] Refer to the instruction manual Figures 1-13 A water quality environment monitoring device suitable for anti-algae interference in smart agricultural greenhouses includes a bracket 1, a vertically arranged connecting bracket 2 is installed on the bracket 1, a cross bar 3 is fixedly installed on the bottom of the connecting bracket 2, and two closing components 5 are sequentially arranged at the front end of the cross bar 3, one of the closing components 5 is fixed to the end of the cross bar 3, and the two closing components 5 are connected and fixed by a connecting pipe 6. The two closing components 5 are used to press together with the inner wall of the cultivation pipe 600, so that a gap is formed between the two closing components 5 and the cultivation pipe 600. A closed cavity 500 is formed; a pumping component 7 is provided between the two closed components 5, a power component 200 and a water pump 9 are provided on the bracket 1, the water pump 9 is connected to the pumping component 7, and the power component 200 is used to drive the pumping component 7 to rotate in the closed cavity 500; the water quality environment monitoring device also includes a monitoring tube 300, a sensor group 400 is installed on the monitoring tube 300, the water pump 9 is used to pump the water in the closed cavity 500 into the interior of the monitoring tube 300 through the pumping component 7, and the sensor group 400 is used to detect the water quality.

[0034] In this embodiment, if Figure 1As shown, the sensor group 400 includes a pH sensor 401, a laser turbidity sensor 402 and a dissolved oxygen sensor 403. The pH sensor 401 is used to detect the pH value of water, the laser turbidity sensor 402 is used to detect the turbidity of water, and the dissolved oxygen sensor 403 is used to detect the amount of dissolved oxygen in water.

[0035] Specifically, during use, the sealing assembly 5 and the pumping assembly 7 are first inserted into the cultivation pipe 600 from the cultivation port 601 of the cultivation pipe 600. Then, the two sealing assemblies 5 are pressed against the inner wall of the cultivation pipe 600 to form a sealed chamber 500 between the two sealing assemblies 5 and the cultivation pipe 600. When monitoring water quality, the water in the sealed chamber 500 and the algae attached to the inner wall of the cultivation pipe 600 need to be pumped into the monitoring tube 300, and then the various water quality indicators are detected by the sensor group 400. Specifically, the water pump 9 pumps the water within the sealed chamber 500 into the monitoring tube 300 via the pumping assembly 7. However, simply pumping the water into the monitoring tube 300 does not draw the algae into the monitoring tube 300. Therefore, the water pump 9 further pumps the water from the monitoring tube 300 into the sealed chamber 500 to flush the inner wall of the cultivation pipe 600 multiple times, thereby flushing the algae from the inner wall of the cultivation pipe 600. Finally, all the water in the sealed chamber 500 is pumped into the monitoring tube 300. The pH sensor 401, laser turbidity sensor 402, and dissolved oxygen sensor 403 are then used to monitor the water quality within the cultivation pipe 600. The algae are mixed in the water, and their concentration can be detected by the laser turbidity sensor 402. Since the cultivation pipe 600 has multiple cultivation ports 601, the device can monitor at each of the cultivation ports 601, achieving multi-point monitoring.

[0036] It should be noted that, since the water in the closed cavity 500 needs to be pumped out, a small hole needs to be opened on the surface of the cultivation pipe 600 at the position corresponding to the closed cavity 500 to balance the internal and external pressures and facilitate the pumping out of the water in the closed cavity 500.

[0037] The above technical solution, through the arrangement of the sealing component 5 and the pumping component 7, can use the two sealing components 5 to separate the closed chamber 500 inside the cultivation pipe 600, and use the pumping component 7 to pump all the water in the closed chamber 500 and the algae attached to the inner wall of the cultivation pipe 600 into the interior of the monitoring tube 300, and detect the water quality through the sensor group 400, thereby achieving the purpose of monitoring the water quality, and the monitoring result is relatively accurate.

[0038] In the above technical solution, if Figures 1-8As shown, the closing component 5 includes a sleeve 51, which has multiple slots 511 in the circumferential direction, a movable sleeve 52 is movably provided in the middle of the sleeve 51, and an air cavity 50 is formed between the movable sleeve 52 and the sleeve 51. An air bag 53 is provided on the outer fixed sleeve of the sleeve 51, and the air cavity 50 is connected with the interior of the air bag 53 through the slot 511. The air cavities 50 of the two closing components 5 are connected through the connecting pipe 6, and an air pump 100 is provided on the bracket 1, which is connected to the air cavity 50 of the closing component 5 near the cross bar 3 through a hose.

[0039] It should be noted that if Figure 6 As shown, the sleeve 51 located on the left side, i.e., near the crossbar 3, is fixedly mounted on the end of the crossbar 3. The sleeve 51 located on the right side, i.e., away from the crossbar 3, is connected to the sleeve 51 on the left side via a connecting pipe 6. A notch 4 is provided at the end of the crossbar 3. A hose is connected at the position of the notch 4, so that one end of the hose is connected to the air cavity 50 of the left sleeve 51, and the other end of the hose is connected to the air pump 100. In this way, the air pump 100 can pump air into the air cavity 50 of the left sleeve 51 through the hose. The air can enter the air cavity 50 of the right sleeve 51 through the connecting pipe 6. The air in the air cavity 50 can enter the interior of the air bag 53 through the notch 511, thereby causing the air bag 53 to swell. The air bag 53 can then withstand the inner wall of the cultivation pipe 600, thereby forming a closed chamber 500. When the air pump 100 is evacuated, the air bag 53 is separated from the inner wall of the cultivation pipe 600.

[0040] Furthermore, a reinforcing rod 54 is hinged on the inner side of the slot 511, and one end of the reinforcing rod 54 located outside the envelope 51 is fixedly connected to the inner top wall of the airbag 53. A sliding groove 541 is provided on the one end of the reinforcing rod 54 located inside the envelope 51, and a pin shaft 521 is fixedly connected to the movable sleeve 52, and the pin shaft 521 slides inside the sliding groove 541.

[0041] It should be noted that if Figure 5-Figure 8 As shown, the airbag 53 is in an inflated state and the reinforcing rod 54 is in an expanded state. When the movable sleeve 52 moves to the right, the pin 521 is driven to move. The pin 521 slides inside the slide groove 541 and pushes the reinforcing rod 54 to rotate counterclockwise, so that the reinforcing rod 54 is transformed into a contracted state.

[0042] In the above technical solution, if Figure 5-10As shown, the pumping assembly 7 comprises a rotating sleeve 71, the connecting pipes 6 are provided with a plurality of rotating sleeves 71, the rotating sleeve 71 is sleeved outside the plurality of connecting pipes 6, the two ends of the rotating sleeve 71 are in contact with the end walls of the two side sealing sleeves 51, the rotating shafts 72 are arranged between the adjacent connecting pipes 6, the middle part of the crossbar 3 is movably inserted with a middle shaft 8, the middle part of the middle shaft 8 is provided with a water channel 81, one end of the middle shaft 8 sequentially passes through the middle part of one sealing sleeve 51, the middle part of the rotating sleeve 71, the middle part of the other sealing sleeve 51, and the middle shaft 8 is rotatably connected with the movable sleeves 52 of the two sealing assemblies 5, the rotating shafts 72 are in contact and pressed with the inner wall of the rotating sleeve 71 and the outer wall of the middle shaft 8, the water cavity 70 is formed between the middle shaft 8 and the rotating sleeve 71, the water channel 81 is in communication with the water cavity 70, and the water pump 9 is in communication with one end of the water channel 81 through a hose.

[0043] It should be noted that the crossbar 3 is fixed and does not move, when the middle shaft 8 moves, the movable sleeve 52 can be driven to move, so that the movable sleeve 52 drives the reinforcing rod 54 to convert between the expanded state and the contracted state. When the middle shaft 8 rotates, the middle shaft 8 drives the rotating shaft 72 to rotate, the rotating shaft 72 drives the rotating sleeve 71 to rotate, and the rotating sleeve 71 drives the water nozzle 73 to rotate.

[0044] Further, the outer side of the pumping assembly 7 is provided with a water nozzle 73, the water nozzle 73 comprises a soft pipe 731, the soft pipe 731 is fixed on the outer wall of the rotating sleeve 71 and is in communication with the water cavity 70, one end of the soft pipe 731 is fixedly connected with a hard pipe 732, the end of the hard pipe 732 is provided with a water head 733, a plurality of water holes 734 are formed in the side wall of the water head 733, and a one-way valve 735 is mounted on the bottom of the water head 733.

[0045] It should be noted that when the water pump 9 pumps water, the water in the sealed cavity 500 can enter the water head 733 from the position of the one-way valve 735, then enter the inside of the water cavity 70 from the hard pipe 732 and the soft pipe 731, and finally be pumped into the inside of the monitoring barrel 300 through the water channel 81. When the water pump 9 sends the water in the monitoring barrel 300 into the inside of the sealed cavity 500, the water is discharged from the water holes 734 after passing through the water channel 81, the water cavity 70, the soft pipe 731 and the hard pipe 732. It should be noted that when the water pump 9 pumps water, the water can enter the hard pipe 732 from the position of the one-way valve 735, but because the water hole 734 is small, the water can also enter the hard pipe 732 from the position of the one-way valve 735.

[0046] In the above technical solution, as shown, Figure 1-Figure 3 The power assembly 200 comprises a motor 201, the output end of the motor 201 is fixedly connected with a vertical main shaft 202, the main shaft 202 is rotatably connected with the connecting frame 2, the bottom of the main shaft 202 is fixedly connected with a bevel gear one 203, the end of the crossbar 3 is rotatably connected with a bevel gear two 204, the bevel gear two 204 is engaged with the bevel gear one 203, and the bevel gear two 204 is axially slidably connected with the middle shaft 8.

[0047] It should be noted that the bevel gear 204 is axially slidably connected to the central shaft 8. Specifically, a spline groove is provided on the central shaft 8, and a spline is provided inside the bevel gear 204. The spline slides in the spline groove. The motor 201 drives the main shaft 202 to rotate, and the main shaft 202 can drive the central shaft 8 to rotate through the bevel gear 1 203 and the bevel gear 2 204.

[0048] Furthermore, an electric push rod 205 is installed on the bracket 1 , and the output end of the electric push rod 205 is fixedly connected to a shift fork 206 . The end of the central shaft 8 has an annular groove 207 , and the bottom end of the shift fork 206 is movably inserted into the annular groove 207 .

[0049] It should be noted that the bottom of the fork 206 is a Y-shaped structure, which is inserted into the annular groove 207, so that the central axis 8 can rotate relative to the fork 206. When the electric push rod 205 drives the fork 206 to move, the fork 206 can push the central axis 8 to move.

[0050] In this embodiment, when monitoring water quality: First, when the reinforcing rod 54 is in the retracted state, the cross bar 3, the central axis 8, the closing component 5 and the pumping component 7 are obliquely inserted into the interior of the cultivation pipe 600 from the position of the cultivation port 601, and then straightened after insertion, and the bracket 1 is placed on the outer surface of the cultivation pipe 600.

[0051] Then, electric push rod 205 drives central shaft 8 to move via shift fork 206. Central shaft 8 drives movable sleeve 52 to move leftward, which in turn drives pin 521 to move. Pin 521 slides within slide slot 541, driving reinforcing rod 54 to rotate clockwise, thereby transforming reinforcing rod 54 from a retracted state to an expanded state. The expanded reinforcing rod 54 presses against the inner wall of cultivation pipe 600. Air pump 100 pumps air, which enters air cavity 50 of left envelope 51 through hose and then into air cavity 50 of right envelope 51 through connecting pipe 6. The air in air cavity 50 enters airbag 53 through notch 511, causing airbag 53 to inflate. Airbag 53 presses against the inner wall of cultivation pipe 600, thereby forming a sealed chamber 500 between the two airbags 53 and the inner wall of cultivation pipe 600.

[0052] Secondly, the water pump 9 pumps the water in the closed chamber 500 from the position of the one-way valve 735 through the water head 733, the hard pipe 732, the soft pipe 731, the water chamber 70, and the water channel 81 into the interior of the monitoring tube 300. After the pumping is completed, the algae on the inner wall are processed. Specifically, the motor 201 drives the central shaft 8 to rotate through the main shaft 202, the bevel gear 1 203 and the bevel gear 2 204. The central shaft 8 drives the rotating shaft 72 to rotate. The rotating shaft 72 drives the rotating sleeve 71 to rotate. The rotating sleeve 71 drives the water nozzle 73 During the rotation of the water nozzle 73, the water pump 9 draws the water in the monitoring cylinder 300 into the interior of the closed chamber 500, and the water is sprayed out from the water hole 734 to flush the inner wall of the cultivation pipe 600. After flushing, the water nozzle 73 stops rotating and then draws the flushing water into the monitoring cylinder 300. The flushing is repeated several times to ensure that all the algae are flushed down, and then the remaining water is pumped into the monitoring cylinder 300 again. In order to prevent the hose from being entangled, the water nozzle 73 can be rotated back and forth when it is driven to rotate.

[0053] Furthermore, the water quality is detected by the pH sensor 401 , the laser turbidity sensor 402 and the dissolved oxygen sensor 403 , including the pH value, the turbidity of the water and the amount of dissolved oxygen in the water.

[0054] Finally, the air pump 100 extracts the air in the two air bags 53, and causes the central axis 8 to drive the movable sleeve 52 to move to the right, so as to drive the reinforcing rod 54 from the expanded state to the contracted state, and then the device can be taken out from the position of the cultivation port 601. The same operation is performed on the cultivation ports 601 at other positions to realize multi-point monitoring.

[0055] It should be noted that the purpose of setting the reinforcing rod 54 is to improve the stability of the support of the airbag 53, so as to prevent the water on the other side of the airbag 53 from squeezing the airbag 53 after the water in the closed cavity 500 is pumped out, causing large deformation, so as to avoid external water from flowing into the interior of the closed cavity 500.

[0056] In this embodiment, if Figure 1-Figure 2 As shown, the bracket 1 includes a bottom plate 11, a top plate 12 is arranged above the bottom plate 11, and columns 13 are fixedly connected around the bracket 1. The top plate 12 is sleeved on the columns 13, and a spring 14 is sleeved on the columns 13. The spring 14 is used to reset the top plate 12 upward.

[0057] It should be noted that the water pump 9, air pump 100, motor 201 and electric push rod 205 are all installed on the top plate 12. When in use, the bottom plate 11 is supported on the cultivation pipe 600. Through the setting of the column 13 and the spring 14, when the airbag 53 presses the side wall of the cultivation pipe 600, the position of the top plate 12 can be fine-tuned so that the cross bar 3 and the central axis 8 are located on the axis of the cultivation pipe 600.

[0058] In this embodiment, the reinforcing rods 54 on the two closing components 5 can be staggered so that the contracted volume is smaller when in the contracted state. It should also be noted that through the setting of the soft pipe 731, when the reinforcing rods 54 contract, the airbag 53 can also bend the water nozzle 73 at the position of the soft pipe 731, so that the water nozzle 73 also contracts, so that it is easy to take out from the cultivation port 601.

[0059] like Figure 13 As shown, this embodiment also provides a water quality environment monitoring method suitable for smart agricultural greenhouses to resist algae interference, using the above-mentioned water quality environment monitoring device suitable for smart agricultural greenhouses to resist algae interference, including the following steps: Step 1: Insert the sealing component 5 and the pumping component 7 into the interior of the cultivation pipe 600 from the cultivation port 601 of the cultivation pipe 600; Step 2: Press the two sealing components 5 against the inner wall of the cultivation pipe 600 to form a closed cavity 500 between the two sealing components 5 and the cultivation pipe 600; Step 3: The water pump 9 pumps the water in the sealed chamber 500 into the interior of the monitoring tube 300 through the pumping assembly 7. The water pump 9 also pumps the water in the interior of the monitoring tube 300 into the sealed chamber 500 to flush the inner wall of the cultivation pipe 600 multiple times, and finally pumps the water in the sealed chamber 500 into the interior of the monitoring tube 300. Step 4: The sensor group 400 detects the water quality environment in the monitoring tube 300, thereby obtaining the water quality environment in the cultivation pipe 600, thereby realizing water quality monitoring.

[0060] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
