DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present application will be described clearly and completely below with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work belong to the protection scope of the present application.

[0038] Embodiment one

[0039] With reference to Figure 1 The present application provides a technical solution: a shrimp-rice symbiotic rice field early warning management system, comprising:

[0043] A data storage unit for receiving and storing the data issued by the processor;

[0044] A data sending module controlled by the processor and sending the dissolved oxygen content to the user end;

[0045] An oxygen supply device controlled by the processor to increase the oxygen in the rice field water;

[0046] An alarm unit controlled by the processor to issue an alarm for early warning when the dissolved oxygen content in the rice field is too low.

[0047] Embodiment two

[0048] With reference to Figures 2-4 An automatic oxygen supply device of a shrimp-rice symbiotic rice field early warning management system, comprising a gas pump 1 controlled by a processor, a base 11 fixedly connected to the bottom of the gas pump 1, the base 11 being placed at the edge of the rice field, a first support block 16 and a second support block 4 placed on both sides of the rice field, an air inlet pipe 17 and an air outlet pipe 12 installed on the gas pump 1, a cross pipe 13 installed on the air outlet pipe 12, a plurality of branch pipes 14 rotatably connected to the side wall of the cross pipe 13, the plurality of branch pipes 14 being in communication with the cross pipe 13, the plurality of branch pipes 14 being rotatably connected to the first support block 16 at the end away from the cross pipe 13, a plurality of air jet pipes 15 linearly arranged and fixedly connected to the side wall of the plurality of branch pipes 14, the plurality of air jet pipes 15 being immersed below the liquid level in the rice field.

[0049] When the early warning management system detects that the oxygen content in the paddy field water is reduced, the air pump 1 is controlled to operate. The air pump 1 extracts external air through the air inlet pipe 17, and then sends the air into the horizontal pipe 13 through the air outlet pipe 12. Then the air in the horizontal pipe 13 flows through the branch pipe 14 and is sprayed out from the air injection pipe 15 on the side wall of the branch pipe 14. Since the air injection pipe 15 is immersed below the liquid surface, the oxygen in the air can be partially dissolved in the paddy field water. The number and interval of the air injection pipe 15 can be adjusted according to the planting density and size of the paddy field. The first support block 16 and the second support block 4 support the branch pipe 14. Since the two ends of the branch pipe 14 are rotatable on the first support block 16 and the second support block 4, the air injection angle of the air injection pipe 15 can be changed, so that the oxygen can be increased in a large range in the paddy field.

[0050] Embodiment three

[0051] With reference to Figures 3-6 On the basis of embodiment two, further, the end of the air inlet pipe 17 is fixedly connected with a first cylinder 2, the first cylinder 2 is placed in the ground, the side wall of the first cylinder 2 is fixedly connected with a pressure stabilizing pipe 21, the air inlet pipe 17 and the pressure stabilizing pipe 21 are on the same axis, the upper part of the first cylinder 2 is fixedly connected with a first support 23, the middle part of the first support 23 is fixedly connected with a gas cylinder 24 controlled by a processor, the output end of the gas cylinder 24 is fixedly connected with a cylinder rod 25, the bottom of the cylinder rod 25 is fixedly connected with a first circular plate 26 abutting the inner wall of the first cylinder 2, the top of the first cylinder 2 is fixedly connected with a stop ring 22 for preventing the first circular plate 26 from separating from the first cylinder 2, and the bottom of the first circular plate 26 in the first cylinder 2 is filled with hydrogen peroxide solution.

[0052] The first cylinder 2 is filled with hydrogen peroxide solution, and the air inlet pipe 17 is in communication with the first cylinder 2. When the processor receives data that the oxygen dissolution in the paddy field water is too low, the gas cylinder 24 is controlled to operate, so that the cylinder rod 25 at the output end of the gas cylinder 24 moves upward, and then the first circular plate 26 is moved upward by the cylinder rod 25. When the first circular plate 26 moves to the upper part of the air inlet pipe 17 and the pressure stabilizing pipe 21, the oxygen generated by the decomposition of the hydrogen peroxide solution in the first cylinder 2 is extracted by the air inlet pipe 17. The setting of the pressure stabilizing pipe 21 stabilizes the internal pressure of the first cylinder 2, so that the air extracted by the air pump 1 contains a large amount of oxygen, and more oxygen can be dissolved in the paddy field water.

[0053] The outer wall of the first cylinder 2 is wound with a heating wire 28, and the outer wall of the first cylinder 2 is fixedly connected with a temperature controller 27 for controlling the heating wire 28.

[0054] The processor controls the heating wire 28 to be turned on at the same time, and then the heating wire 28 wound on the outer wall of the first cylinder 2 heats the hydrogen peroxide solution in the inside, so that the decomposition speed of the hydrogen peroxide solution is accelerated, a large amount of oxygen is generated, and the oxygen supply effect on the paddy field water is further improved. The temperature controller 27 controls the heating wire 28, and when the temperature reaches 90 degrees, the heating wire 28 stops running, thereby avoiding the increase of water vapor caused by boiling of hydrogen peroxide into the air pump 1, reducing the service life of the air pump 1.

[0057] Because the drain pipe 29 and the liquid suction pipe 38 are provided with a one-way valve 381, when the first circular plate 26 moves upward in the first cylinder 2, the hydrogen peroxide solution in the second cylinder 3 can be extracted through the liquid suction pipe 38, so that the hydrogen peroxide solution in the second cylinder 3 is transferred to the first cylinder 2, and the hydrogen peroxide solution in the first cylinder 2 is supplemented, and the resistance of the air cylinder 24 is reduced.

[0058] The top of the second cylinder 3 is fixedly connected with the second support 35, the second support 35 is vertically and slidably connected with the slide rod 33, the bottom of the slide rod 33 is fixedly connected with the second circular plate 32, the side wall of the second circular plate 32 is in close contact with the inside of the second cylinder 3, the slide rod 33 is sleeved with the first spring 34, the two ends of the first spring 34 are respectively in abutment with the second circular plate 32 and the second support 35, the upper end surface of the second cylinder 3 is fixedly connected with the stop block 31, the stop block 31 intermittently abuts against the second circular plate 32, the electromagnetic valve 39 controlled by the processor is arranged between the one-way valve 381 and the second cylinder 3 on the liquid suction pipe 38, the oxygen sensor 391 for controlling the air cylinder 24 is arranged on the exhaust pipe 12, the middle part of the second circular plate 32 is fixedly connected with the supplement pipe 36 for supplementing hydrogen peroxide solution into the second cylinder 3, and the valve 37 is arranged on the supplement pipe 36.

[0059] The oxygen sensor 391 is controlled by the processor, and the oxygen sensor 391 is activated only when the cylinder 24 is running, and the solenoid valve 39 is controlled by the processor to open synchronously, so that the liquid suction pipe 38 is in a one-way open state, when the first circular plate 26 runs to the uppermost position, the cylinder 24 stops running, and the solenoid valve 39 is closed, and in the normal state, the solenoid valve 39 is closed, so that the lower part of the second cylinder 3 is sealed, and the second circular plate 32 cannot be separated from the second cylinder 3 under the blocking of the stop block 31, and the upper part of the second cylinder 3 is also in a sealed state, and the setting of the slide rod 33 makes the second circular plate 32 not inclined relative to the second cylinder 3, and the first spring 34 applies pressure to the second circular plate 32, so that the second circular plate 32 has a tendency to slide into the second cylinder 3, and the solenoid valve 39 is in a closed state at this time, so that the pressure of the hydrogen peroxide solution stored in the second cylinder 3 increases, thereby reducing the decomposition rate of the hydrogen peroxide solution, and ensuring the oxygen supply effect of the paddy field water, and when the hydrogen peroxide solution in the second cylinder 3 is consumed, it can be supplemented through the supplement pipe 36 after opening the valve 37, and when the oxygen sensor 391 detects that the oxygen concentration flowing in the exhaust pipe 12 decreases, the cylinder 24 is controlled to run, at this time, the cylinder rod 25 at the output end of the cylinder 24 moves downward, and the first circular plate 26 moves downward, so that the water remaining after the hydrogen peroxide solution in the first cylinder 2 is decomposed is discharged to the paddy field through the liquid discharge pipe 29, so that the water after the hydrogen peroxide solution is decomposed can be utilized, and after the cylinder rod 25 moves to the lowest position, it starts to move upward, and the solenoid valve 39 is controlled by the processor to open again, at this time, the hydrogen peroxide solution in the second cylinder 3 enters the first cylinder 2 for replenishment, and the cycle is repeated to ensure sufficient oxygen supply to the paddy field water.

When the first cylinder 2 is moved downward so that the residue of the hydrogen peroxide solution is discharged, the piston rod 52 is driven to move downward synchronously in the piston cylinder 5, and then the piston cylinder 5 injects the cooling liquid into the cooling tank 54 through the lower pipeline 55, and then the cooling liquid in the cooling tank 54 is pumped out through the upper pipeline 55, so that the cooling liquid flows in the cooling tank 54, and then the heated hydrogen peroxide solution residue is cooled when being discharged to the paddy field through the drain pipe 29, so as to avoid the high-temperature water from scalding the rice or shrimps in the paddy field.

[0063] Embodiment six

[0064] With reference to Figure 8 and Figure 9 Further, the insertion rod 41 is slidably connected in the exhaust pipe 12, the side wall of the insertion rod 41 is attached to the inner wall of the exhaust pipe 12, the transverse pipe 13 is provided with a through hole matched with the insertion rod 41, the middle part of the insertion rod 41 is fixedly connected with a limiting plate 42, the insertion rod 41 is sleeved with a second spring 43, the two ends of the second spring 43 are fixedly connected with the second supporting block 4 and the limiting plate 42 respectively, the end part of the insertion rod 41 is fixedly connected with a wedge block 44, the upper part of the second supporting block 4 is linearly slidably connected with a sliding block 45, the middle part of the sliding block 45 is fixedly connected with a pushing block 47, the middle part of the pushing block 47 is provided with a through hole matched with the wedge block 44 and is provided with an inclination matched with the inclined surface of the wedge block 44 in the through hole, and the end part of the second supporting block 4 is fixedly connected with a magnet 401 magnetically attracted to the sliding block 45.

[0065] The air pump 1 is affected by the voltage so that the output air cannot be linear and uniform, and then the air flowing through the exhaust pipe 12 can intermittently push the insertion rod 41, and the reaction force of the second spring 43 to the insertion rod 41 makes the insertion rod 41 linearly reciprocate, and then the reciprocating insertion rod 41 drives the wedge block 44 to synchronously reciprocate, at this time, the reciprocating wedge block 44 intermittently presses the pushing block 47, so that the pushing block 47 drives the sliding block 45 to linearly slide on the second supporting block 4 and away from the magnet 401, and when the wedge block 44 is away from the pushing block 47, the magnet 401 is attracted to the sliding block 45, so that the sliding block 45 is reset, and then the reciprocating insertion rod 41 can drive the sliding block 45 to synchronously reciprocate.

[0066] The two ends of the branch pipe 14 are fixedly connected with a rotating ring 48 and are rotatably connected with the transverse pipe 13 and the first supporting block 16 through the rotating ring 48, the side wall of the rotating ring 48 close to the branch pipe 14 is fixedly connected with a rectangular plate 49, the side wall of the sliding block 45 is fixedly connected with a pushing rod 46, and the rectangular plate 49 is provided with a through slot matched with the pushing rod 46.

[0067] When the slider 45 reciprocating sliding can be through the lever 46 to the rectangular plate 49, so that the rectangular plate 49 reciprocating swing, and then the rectangular plate 49 through the rotating ring 48 driven branch pipe 14 reciprocating rotation, and then the jet pipe 15 jet range expansion, so that the oxygenation effect of the paddy field water is improved.

[0068] The exhaust pipe 12 is placed in the dehumidification cotton.

[0069] The dehumidification cotton in the exhaust pipe 12 can prevent the water vapor in the first cylinder 2 from entering the air pump 1, thereby ensuring the service life of the air pump 1.

[0070] Working principle: the shrimp rice symbiotic paddy field automatic oxygen supply device, the early warning management system detects the oxygen content in the paddy field water decreases when the control air pump 1 operation, air pump 1 through the air inlet pipe 17 extraction of external air, and then through the exhaust pipe 12 into the horizontal pipe 13 air, then the air in the horizontal pipe 13 through the branch pipe 14 flow and from the branch pipe 14 side wall on the jet pipe 15 jet, because the jet pipe 15 immersed in the liquid surface, thereby making the oxygen in the air can be partially dissolved in the paddy field water, the number and interval of the jet pipe 15 can be adjusted according to the planting density and the size of the paddy field, the first support block 16 and the second support block 4 make the branch pipe 14 get support, because the branch pipe 14 both ends rotating in the first support block 16 and the second support block 4, thereby making the jet angle of the jet pipe 15 change, so that the oxygen can be increased in a large range in the paddy field.

[0071] The first cylinder 2 is placed in the hydrogen peroxide solution, and the air inlet pipe 17 is communicated with the first cylinder 2, and the processor receives the data of the paddy field water dissolved oxygen content is too low, the control air cylinder 24 operation, so that the cylinder rod 25 on the output end of the air cylinder 24 moves up, and then the cylinder rod 25 drives the first circular plate 26 to move up, when the first circular plate 26 moves up to the air inlet pipe 17 and the upper part of the stabilizing pipe 21, the oxygen produced by the decomposition of the hydrogen peroxide solution in the first cylinder 2 will be extracted by the air inlet pipe 17, the setting of the stabilizing pipe 21 makes the internal pressure of the first cylinder 2 stable, and then the air extracted by the air pump 1 contains a large amount of oxygen, so that more oxygen can be dissolved in the paddy field water.

[0072] The processor controls the heating wire 28 to open, and then the heating wire 28 wound on the outer wall of the first cylinder 2 heats the hydrogen peroxide solution in it, so that the decomposition rate of the hydrogen peroxide solution is accelerated, and a large amount of oxygen is produced, which further improves the oxygen supply effect of the paddy field water. The temperature controller 27 controls the heating wire 28, and when the temperature reaches 90 degrees, the heating wire 28 stops running, thereby avoiding the increase of water vapor caused by the boiling of hydrogen peroxide into the air pump 1, which reduces the service life of the air pump 1.

[0073] Since the one-way valve 381 is arranged on the liquid discharge pipe 29 and the liquid suction pipe 38, when the first circular plate 26 moves upward in the first cylinder 2, the hydrogen peroxide solution in the second cylinder 3 can be extracted through the liquid suction pipe 38, so that the hydrogen peroxide solution in the second cylinder 3 is transferred to the first cylinder 2, so that the hydrogen peroxide solution in the first cylinder 2 is supplemented, and the resistance of the cylinder 24 is reduced.

[0074] The oxygen sensor 391 is controlled by the processor, and the oxygen sensor 391 is activated only when the cylinder 24 is running. The electromagnetic valve 39 is controlled by the processor at the same time, and the electromagnetic valve 39 is opened synchronously. The liquid suction pipe 38 is in a one-way open state. When the first circular plate 26 runs to the uppermost part, the cylinder 24 stops running, and the electromagnetic valve 39 is closed. In the normal state, the electromagnetic valve 39 is closed, so that the lower part of the second cylinder 3 is sealed, and the second circular plate 32 cannot be separated from the second cylinder 3 under the blocking of the stop block 31. The upper part of the second cylinder 3 is also in a sealed state. The setting of the slide rod 33 makes the second circular plate 32 not inclined relative to the second cylinder 3. The first spring 34 exerts pressure on the second circular plate 32, so that the second circular plate 32 has a tendency to slide into the second cylinder 3. At this time, the electromagnetic valve 39 is in a closed state, so that the pressure of the hydrogen peroxide solution stored in the second cylinder 3 is increased, thereby reducing the decomposition rate of the hydrogen peroxide solution, ensuring the oxygen supply effect on the paddy field water. When the hydrogen peroxide solution in the second cylinder 3 is consumed, it can be supplemented through the supplement pipe 36 after the valve 37 is opened. When the oxygen sensor 391 detects that the oxygen concentration flowing in the exhaust pipe 12 is reduced, the cylinder 24 is controlled to run. At this time, the cylinder rod 25 at the output end of the cylinder 24 moves downward, and then the first circular plate 26 moves downward, so that the water remaining after the hydrogen peroxide solution in the first cylinder 2 is decomposed is discharged to the paddy field through the liquid discharge pipe 29, so that the water after the hydrogen peroxide solution is decomposed can be utilized. After the cylinder rod 25 moves to the lowest position, it starts to move upward, and the electromagnetic valve 39 is controlled by the processor to be opened again. At this time, the hydrogen peroxide solution in the second cylinder 3 enters the first cylinder 2 to supplement, so as to circulate and work, and ensure the sufficient oxygen supply amount of the paddy field water.

[0075] The hydrogen peroxide solution in the first cylinder 2 and the second cylinder 3 has sufficient purity, so that the remaining material after the oxygen is decomposed is water. When the cylinder rod 25 moves downward to make the hydrogen peroxide solution in the first cylinder 2 decompose and the remaining material be discharged, the piston rod 52 is driven to move downward in the piston cylinder 5 synchronously. Then, the piston cylinder 5 injects the cooling liquid into the cooling box 54 through the lower pipeline 55, and then extracts the cooling liquid in the cooling box 54 through the upper pipeline 55, so that the cooling liquid flows in the cooling box 54, and then the remaining material of the hydrogen peroxide solution after being heated is discharged to the paddy field through the liquid discharge pipe 29, so that the remaining material can be cooled, and the high-temperature water will not scald the rice or shrimps in the paddy field.

[0076] The air pump 1 is affected by voltage so that the output air cannot be linear and uniform, and then the air flowing through the exhaust pipe 12 can intermittently push the plug rod 41, cooperating with the reaction force of the second spring 43 on the plug rod 41, so that the plug rod 41 can slide linearly and reciprocally, and then the reciprocally sliding plug rod 41 drives the wedge block 44 to synchronously reciprocally slide, at this time the reciprocally sliding wedge block 44 intermittently extrudes the push block 47, so that the push block 47 drives the sliding block 45 to slide linearly on the second support block 4 and away from the magnet 401, and when the wedge block 44 is away from the push block 47, the magnet 401 adsorbs the sliding block 45, so that the sliding block 45 resets, and then the reciprocally sliding plug rod 41 can drive the sliding block 45 to synchronously reciprocally slide.

[0077] When the sliding block 45 reciprocally slides, the rectangular plate 49 can be pushed by the push rod 46, so that the rectangular plate 49 swings reciprocally, and then the rectangular plate 49 drives the branch pipe 14 to reciprocally rotate through the rotating ring 48, and then the jet pipe 15 expands the range of jetting, so that the oxygenation effect of the paddy field water is improved.

[0078] The dehumidifying cotton in the exhaust pipe 12 can prevent the water vapor in the first cylinder 2 from entering the air pump 1, and then ensure the service life of the air pump 1.

[0079] Although the embodiments of the present application have been shown and described, it is to be understood that various modifications, substitutions, replacements and changes can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
