Description

Technical Field

[0001] The invention relates to the technical field of forestry sprinkler irrigation, in particular to a forestry sprinkler irrigation device capable of being adjusted at multiple angles. Background Art

[0002] Forestry sprinkler irrigation is an irrigation method that simulates natural rainfall by spraying water onto trees through nozzles. The nozzles can be installed on a fixed pipe system or on a mobile device. This irrigation method can evenly distribute water over a large area of ​​forest, effectively meeting the water needs of trees. It is not restricted by terrain and can play a good role in both mountainous areas and plains. It can also reduce soil erosion, save water, and has positive significance for maintaining the ecological environment of forest areas.

[0003] Center pivot irrigation is a commonly used method of forestry irrigation. It is an irrigation technology that uses rotating sprinkler nozzles to achieve water spray coverage. The sprinkler nozzles rotate around the central axis to spray water outward in a fan or circular shape. Its advantage is that it can accurately control the irrigation range and water volume, has high irrigation efficiency, and can quickly irrigate large areas.

[0004] During rotary irrigation, each device is responsible for irrigation within a certain range. During irrigation, the angle between the nozzle and the ground is generally forty-five degrees. This angle allows the maximum spraying distance under the same pressure. However, during irrigation, due to the external wind, the water column sprayed outward through the nozzle will be blocked by the wind under the influence of external wind force, and may not reach the preset position. When facing with the wind, the water column reaches a farther position due to the influence of the wind, and when facing against the wind, the water column reaches a closer position under the influence of the wind, resulting in the actual spraying range failing to reach the preset range, thus affecting the irrigation effect.

[0016] 2. The multi-angle adjustable forestry sprinkler irrigation equipment uses the wind speed data detected by the wind direction and wind speed sensor to start the second electric push rod through the controller. The greater the wind speed, the longer the second electric push rod extends, the greater the suction or repulsion generated by the first magnet block and the second magnet block, and the greater the up and down swing distance of the sprinkler head.

The auxiliary component 4 includes a turntable 41, and the turntable 41 is rotatably connected to the outside of the central tube 21. An extension plate 42 is fixedly installed on the outside of the turntable 41, and a second electric push rod 43 is fixedly installed on the bottom of both ends of the extension plate 42. The output end of the second electric push rod 43 movably passes through the extension plate 42. A first magnet block 44 is fixedly installed on the top of the output end of the second electric push rod 43, and the upper half of the magnetic poles of the first magnet blocks 44 on both sides are opposite. A second magnet block 45 is fixedly installed on the outside of the bottom of the nozzle 27.

[0025] Support legs 5 are fixedly installed at the four corners of the bottom of the support block 1, a water inlet pipe 22 is fixedly installed on the side of the central tube 21, and the water inlet pipe 22 is connected to the inside of the central tube 21, and a wind direction and speed sensor 6 is fixedly installed on the top of the internal box 23. A clamping ring 213 is fixedly installed on the outside of the internal box 23, and a connecting groove 214 is opened inside the clamping ring 213. The clamping ring 213 is rotatably connected to the inside of the rotating box 24, the central tube 21 is connected to the inside of the internal box 23, and the internal box 23 is connected to the inside of the rotating box 24 through the connecting groove 214. A connecting pipe 212 is fixedly installed between the rotating box 24 and the nozzle 27, and the nozzle 27 is connected to the inside of the rotating box 24 through the connecting pipe 212. A first gear ring 28 is fixedly installed at the bottom of the rotating box 24, a support plate 211 is fixedly installed on the outside of the central tube 21, a first motor 210 is fixedly installed on the top of the support plate 211, a first gear 29 is fixedly installed at the output end of the first motor 210, the first gear 29 and the first gear ring 28 are meshed with each other, and a counterweight 25 is fixedly installed on the outside of the rotating box 24 and on the other side of the nozzle 27.

[0026] A controller is fixedly installed inside the support block 1, and the controller is electrically connected to the first electric push rod 39 and the wind direction and speed sensor 6. The controller is also electrically connected to the second electric push rod 43, the first motor 210, the self-locking motor 411, the electric slide rail 414 and the first electric push rod 39.

[0027] In this embodiment, the water inlet pipe 22 is connected to a water pump outside, and water is pumped from the outside by the water pump and then enters the water inlet pipe 22 for water supply. The water volume and water pressure of the water inlet are controlled by the power of the water pump, and then the distance of the initial water spraying of the nozzle 27 is controlled. The water inside the water inlet pipe 22 enters the center tube 21, then enters the inner box 23, and then enters the rotating box 24 through the connecting groove 214, and then enters the nozzle 27 through the connecting pipe 212 and finally sprays out through the nozzle 27. When the rotating box 24 rotates around the inner box 23, it does not affect the water passing through the connecting groove 214. During irrigation, the first motor 210 is started to drive the first gear 29 to rotate, and the first gear 29 rotates to drive the first gear ring 28 to rotate. The first gear ring 28 rotates to realize the rotation box 24 around the inner box 23, thereby driving the outer nozzle 27 to rotate around the center. The nozzle 27 sprays water while rotating around the center, so as to realize circular irrigation within a certain range. When the rotating box 24 rotates, the counterweight block 25 on the other side balances the force generated when the other side of the nozzle 27 rotates, thereby ensuring the stable rotation of the nozzle 27 and the rotating box 24. During irrigation, the wind direction and wind speed sensor 6 can detect the wind speed and wind direction in real time. After detecting the wind direction, the wind direction information is transmitted to the controller, and the controller can start the self-locking motor 411 to drive the second gear 412 to rotate. The rotation of the second gear 412 drives the second gear ring 410 to rotate. The rotation of the second gear ring 410 drives the turntable 41 to rotate. The rotation of the turntable 41 drives the outer extension plate 42 to rotate, thereby changing the position of the two outer first magnet blocks 44, making the straight line where the two first magnet blocks 44 are located parallel to the wind direction, and realizing the change according to the detected wind direction through the program preset by the controller. The angle is changed, the name of the magnetic pole above the first magnet block 44 on the windward side is opposite to the name of the magnetic pole below the second magnet block 45, and the two can attract each other. The name of the magnetic pole above the first magnet block 44 on the downwind side is the same as the name of the magnetic pole below the second magnet block 45, and the two repel each other, so that when the nozzle 27 rotates to the windward side, the two magnet blocks attract each other, and the nozzle 27 swings downward. When the nozzle 27 is on the downwind side, the two magnet blocks repel each other and the nozzle 27 swings upward. When the nozzle 27 swings, the gas spring 35 contracts or stretches. After leaving the magnet range, the nozzle 27 is reset under the elastic force of the gas spring 35, and the gas spring 35 is used to adjust the nozzle 27. The spring 35 can also ensure that when the nozzle 27 is reset, due to its vibration absorption characteristics, the nozzle 27 will not swing back and forth, and when the nozzle 27 swings downward, under the limit of the pull plate 33, the baffle 31 moves upward relatively, and vice versa when the nozzle 27 swings upward, the baffle 31 moves downward relatively, and when the baffle 31 moves upward, the distance between the adjustment groove 36 in contact with the nozzle 27 outlet is smaller, and when the baffle 31 moves downward, the distance between the adjustment groove 36 in contact with the nozzle 27 outlet is larger, so that when the nozzle 27 swings downward, the water flow sprayed is thinner and the water pressure is higher, and vice versa when the nozzle 27 swings upward, the water pressure sprayed is lower. The nozzle 27 is thicker, and the angle is out of the optimal spray angle when it swings up and down, so the spray distance will be reduced. Since the water pressure increases when the nozzle 27 swings down, the spray distance can be increased, and when the water pressure increases, it is in the windward direction. The larger water pressure can better reduce the impact of strong winds, and the smaller spray angle can reduce the contact area between the entire water flow and the wind on the vertical plane, and can also reduce the impact of wind on the water flow when facing the wind. Therefore, the spray angle is automatically reduced on the windward side to increase the spray water pressure, which can ensure that the impact of wind on the water flow spray distance is reduced to a minimum, thereby ensuring that the spray range of the windward side can remain basically unchanged;On the contrary, when facing the wind, a larger spray angle and lower water pressure will both reduce the spray range. However, this time it is the wind side, and the larger spray angle makes the entire water column contact area with the wind on the vertical plane larger, and the force of the wind on the water flow becomes larger. At this time, the water pressure is lower and the flow rate is lower, so the wind can blow the water flow better. Therefore, under the blowing of the wind, the water flow can be sprayed over a farther range, and combined with the spray range reduced by reducing the water pressure and increasing the spray height, it is ensured that when facing the wind, the spray range can also remain basically unchanged. Except for the vicinity of the windward and windward sides, the wind in other parts basically blows from the side of the water flow, and its influence on the spray range of the water flow is relatively small, far less than the influence brought by the windward and windward sides. Therefore, this method can ensure that the overall irrigation range can be basically guaranteed to be within the preset range in windy weather, and the spray range can also be guaranteed when the wind direction changes, thus ensuring the irrigation effect; And when strong wind is detected, the wind speed is detected in real time by the wind direction and wind speed sensor 6. The greater the wind speed, the greater the impact on the water flow. At this time, the data is transmitted to the inside of the controller according to the detected wind speed. Through the preset program, the second electric push rod 43 is started according to the transmitted wind speed data. The greater the wind speed, the longer the distance the second electric push rod 43 extends, and the greater the distance the two first magnet blocks 44 move up. At this time, the suction or repulsion generated by the first magnet block 44 and the second magnet block 45 is greater, so the distance the nozzle 27 swings up or down is greater. The distance of the nozzle 27 swinging down increases, the angle of the sprayed water flow is smaller, and the water pressure is greater. Therefore, it can better resist the increasing wind speed and ensure that the spray is near the preset range. The distance of the nozzle 27 swinging up increases, the angle of the sprayed water flow is larger, and the water pressure is smaller. At this time, it is more susceptible to the influence of wind force. Under the influence of the wind direction, the water flow is maintained near the preset spraying range, thereby realizing the real-time adjustment of the up and down swinging distance according to the wind speed, ensuring that the irrigation range can be basically maintained within the preset range when facing different wind speeds, thereby ensuring the irrigation effect.

[0028] Reference Figures 1 to 8 In one aspect of the present embodiment, a vertical plate 34 is fixedly mounted on the top of the rotating box 24, a pull plate 33 is fixedly mounted on the top of the vertical plate 34, the top of the pull plate 33 is hinged to the top of the baffle 31, and a gas spring 35 is hinged between the vertical plate 34 and the nozzle 27.

[0029] A second gear ring 410 is fixedly installed at the bottom of the turntable 41, an electric slide rail 414 is fixedly installed on the top of the support block 1, a track slider 413 is slidably connected to the outer side of the electric slide rail 414, a self-locking motor 411 is fixedly installed on the top of the track slider 413, a second gear 412 is fixedly installed on the output end of the self-locking motor 411, and the second gear 412 is meshed with the second gear ring 410.

[0030] In this embodiment, when it is detected that the wind speed is extremely high, the water column sprayed out at this time is easily affected in all directions. At this time, the nozzle 27 is stopped first, and the first magnet block 44 is moved to the bottom of the second magnet block 45 by starting the self-locking motor 411. The magnetic poles of the first magnet block 44 moved to the bottom and the side opposite to the second magnet block 45 are opposite. At this time, the third electric push rod 46 is started to drive the rubber block 47 to move upward and insert it into the matching groove 49. Then, the electric slide rail 414 drives the track slider 413 to move, and the second gear 412 is disengaged from the second gear ring 410. After disengagement, when the upper nozzle 27 rotates, the third electric push rod 46 can drive the lower turntable 41 to rotate synchronously. The nozzle 27 is swung downward to the minimum angle under the action of the two magnets. At this time, the water pressure of the sprayed water flow is the largest under the influence of the adjusting groove 36. At this time, the sprayed water flow tends to be horizontal, and the contact area between the water flow and the wind is the largest, and the pressure is also the largest, so that the influence of the wind on the water flow in all directions is small, and under the effect of lowering the angle and increasing the water pressure, the irrigation range can be guaranteed to be near the preset range, thereby ensuring the irrigation range on extremely windy days, thereby ensuring the irrigation effect.

[0031] Reference Figures 1 to 8 In one aspect of the present embodiment, a third electric push rod 46 is fixedly mounted on the top of the turntable 41, a rubber block 47 is fixedly mounted on the output end of the third electric push rod 46, a rubber ring 48 is fixedly mounted on the bottom of the rotating box 24, a matching groove 49 is provided inside the rubber ring 48, and the matching groove 49 is located directly above the rubber block 47. The two matching grooves 49 are respectively located on the inner side of the nozzle 27 and the inner side of the counterweight block 25.

[0032] A first atomizing net 37 is fixedly installed inside the nozzle 27, and the first atomizing net 37 is located inside the outlet of the nozzle 27. A slide groove 310 is opened on the inside of the nozzle 27, and a second atomizing net 38 is slidably connected inside the slide groove 310. The second atomizing net 38 is located on the inner side of the first atomizing net 37, and the holes of the second atomizing net 38 correspond one to one with those of the first atomizing net 37. A first electric push rod 39 is fixedly installed inside the nozzle 27, and the output end of the first electric push rod 39 is fixedly installed on the side of the second atomizing net 38.

[0033] In this embodiment, during irrigation, the movement of the first electric push rod 39 is started by detecting the wind speed and through the program preset by the controller. The movement of the first electric push rod 39 can drive the second atomizing net 38 to fine-tune the position. When water is sprayed through the nozzle 27, the water flow can be atomized to a certain extent through the first atomizing net 37 and the second atomizing net 38 to ensure the irrigation effect. When the holes of the first atomizing net 37 and the second atomizing net 38 are aligned, the water flow passes through the first atomizing net 37 and the second atomizing net 38 at the same time, so the sprayed atomized water particles are the largest. When the positions of the first atomizing net 37 and the second atomizing net 38 gradually deviate, the water flow passes through the first atomizing net 37 and the second atomizing net 38 respectively, and the atomization degree is higher. The greater the deviation of the holes of the two, the smaller the sprayed water atomized particles. By detecting the external wind speed, when the wind speed is greater, the atomized particles are controlled to be larger, which can ensure better resistance to wind speed, and the higher the atomization effect when the wind speed is smaller, the irrigation effect can be improved.

[0034] The forestry sprinkler equipment can use Siemens S7-1200 as the controller, which is a compact PLC with strong processing power and rich communication interfaces. It is easy to program and adaptable to a variety of automation scenarios. It is paired with Vaisala WMT700 wind direction and speed sensor 6, which is a high-precision meteorological sensor with a wide measurement range, high stability and reliability, and can adapt to harsh outdoor environments.

[0035] During the control process, the wind direction and wind speed sensor 6 transmits the real-time monitored wind direction and wind speed data to the controller. When circular irrigation is required, the controller starts the first motor 210, and the first motor 210 drives the first gear 29 to rotate. The first gear 29 and the first gear ring 28 are meshed with each other, so that the rotating box 24 rotates around the inner box 23, driving the nozzle 27 connected to the outer connecting frame 26 of the rotating box 24 to rotate around the center; If a change in wind direction is detected, the controller starts the self-locking motor 411, which drives the second gear 412 to rotate, and the second gear 412 meshes with the second gear ring 410 to rotate the turntable 41, thereby changing the positions of the two outer first magnet blocks 44 so that the straight line where they are located is parallel to the wind direction; When the nozzle 27 rotates, according to the wind direction, the first magnet block 44 and the second magnet block 45 on the windward side attract each other, and the first magnet block 44 and the second magnet block 45 on the downwind side repel each other, so that the nozzle 27 swings up and down. The swing of the nozzle 27 drives the baffle 31 slidably connected in the outer clamping plate 32 at the top to move relatively. The adjustment groove 36 on the baffle 31 changes the contact distance with the nozzle 27 outlet, thereby adjusting the thickness and water pressure of the water sprayed by the nozzle 27. At the same time, the greater the wind speed, the longer the distance that the controller makes the second electric push rod 43 extend, the greater the suction or repulsion generated by the first magnet block 44 and the second magnet block 45, and the greater the amplitude of the up and down swing of the nozzle 27; When encountering extremely high wind speed, the controller first stops the sprinkler 27 from spraying water, then starts the self-locking motor 411 to move the first magnet block 44 to the bottom of the second magnet block 45, then starts the third electric push rod 46 to drive the rubber block 47 to move upward and insert it into the matching groove 49 opened in the rubber ring 48 at the bottom of the rotating box 24, and then drives the track slider 413 to move through the electric slide rail 414 to disengage the second gear 412 from the second gear ring 410. When the sprinkler 27 rotates, the third electric push rod 46 drives the lower turntable 41 to rotate synchronously to ensure that the first magnet block 44 is always located below the second magnet block 45. Finally, the controller controls the second electric push rod 43 to extend so that the two magnet blocks are in contact, and then retracts the second electric push rod 43, and uses the effect of the magnet to swing the sprinkler 27 downward to the minimum angle, thereby increasing the water pressure of the sprinkler 27 spraying water to resist the influence of strong winds. In addition, the controller will also control the first electric push rod 39 according to the wind speed. The first electric push rod 39 drives the second atomization net 38 slidably connected in the slide groove 310 in the nozzle 27 to fine-tune the position, thereby changing the relative position of the second atomization net 38 and the first atomization net 37 fixed in the nozzle 27. When the wind speed is high, the holes of the first atomization net 37 and the second atomization net 38 are aligned with a high degree, thereby increasing the sprayed atomized water particles to resist the wind speed; when the wind speed is low, the deviation of the holes of the two nets is increased to improve the atomization effect.

[0036] Determination of the telescopic distance of the second electric push rod 43: Under different wind speed environments, the swing effect of the nozzle 27 under the action of the first magnet block 44 and the second magnet block 45 is tested, and the swing amplitude of the nozzle 27 required to ensure the basic stability of the irrigation range under different wind speeds is recorded, and then the corresponding telescopic distance of the second electric push rod 43 is determined, and the corresponding relationship between the wind speed and the telescopic distance of the electric push rod is formed and stored in the controller. When the controller receives the real-time wind speed data, it immediately queries the mapping table to find the corresponding telescopic distance value of the electric push rod, and then outputs an accurate PWM (pulse width modulation) control signal to the drive circuit of the second electric push rod 43. The duty cycle of the PWM signal is proportional to the required telescopic distance of the electric push rod. By adjusting the duty cycle of the PWM signal, the conduction and cutoff time of the power tube in the drive circuit are controlled, and then the speed and operation time of the motor of the second electric push rod 43 are accurately adjusted to achieve accurate control of the telescopic distance of the second electric push rod 43, so as to ensure that under different wind speeds, the nozzle 27 can accurately swing up and down according to the wind direction to maintain the stability of the irrigation range.

[0037] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0038] Working principle: The water inlet pipe 22 is connected to a water pump outside, and the water pump pumps water into the water inlet pipe 22. The water volume and water pressure are controlled by the water pump power, thereby controlling the initial water spraying distance of the nozzle 27. The water flows through the water inlet pipe 22, the central pipe 21, the internal box 23, the connecting groove 214, the rotating box 24, the connecting pipe 212, and then enters the nozzle 27 and is sprayed out. During irrigation, the first motor 210 drives the first gear 29 to rotate, and then drives the first gear ring 28 to rotate, so that the rotating box 24 rotates around the inner box 23, and drives the sprinkler 27 to rotate around the center, so as to realize circular irrigation; the counterweight 25 balances the force generated by the sprinkler 27 when rotating, and ensures stable rotation; The wind direction and wind speed sensor 6 detects the wind speed and wind direction in real time, and the wind direction information is transmitted to the controller; the controller starts the self-locking motor 411 to drive the second gear 412 to rotate, and then drives the second gear ring 410 and the turntable 41 to rotate, so that the position of the outer extension plate 42 and the first magnet block 44 changes; the first magnet block 44 and the second magnet block 45 on the windward side have opposite magnetic poles and attract each other, and the nozzle 27 swings downward; the magnetic poles on the downwind side have the same magnetic poles and repel each other, and the nozzle 27 swings upward; when the nozzle 27 swings, the gas spring 35 contracts or stretches, and resets after leaving the magnet range, and the gas spring 35 can absorb vibration to prevent the nozzle 27 from shaking; when the nozzle 27 swings, the pull plate 33 limits the baffle 31 to move relatively, changing the distance between the adjustment slot 36 and the nozzle 27 outlet, thereby changing the thickness and water pressure of the sprayed water; the windward side reduces the spray angle to increase the water pressure, reduces the influence of wind on the water flow, and ensures the spray range; the larger spray angle and lower water pressure on the downwind side, combined with wind blowing, ensure the spray range; The wind direction and wind speed sensor 6 detects the wind speed and transmits the data to the controller, and the controller starts the second electric push rod 43 according to the preset program; the greater the wind speed, the longer the second electric push rod 43 extends, the greater the upward movement distance of the first magnet block 44, the greater the suction or repulsion with the second magnet block 45, and the greater the swing distance of the nozzle 27; the downward swing distance of the nozzle 27 increases, the water flow angle is smaller, the water pressure is greater, and the ability to resist wind speed is enhanced; the upward swing distance increases, the water flow angle is larger, the water pressure is smaller, and the wind force is used to keep it near the preset spray range; When the wind speed is extremely high, the nozzle 27 is stopped first, and the self-locking motor 411 moves the first magnet block 44 to the bottom of the second magnet block 45, with the magnetic poles opposite; the third electric push rod 46 is started to drive the rubber block 47 to insert into the matching groove 49, and the electric slide rail 414 disengages the second gear 412 from the second gear ring 410; when the nozzle 27 rotates, the third electric push rod 46 drives the turntable 41 to rotate synchronously, and the first magnet block 44 is always below the second magnet block 45; the second electric push rod 43 is extended to make the two magnets contact and then retracted, and the nozzle 27 swings down to the minimum angle. At this time, the water pressure is maximum, the water flow is horizontal, and the wind has little effect on the water flow, ensuring the irrigation range; During irrigation, according to the detected wind speed, the controller starts the movement of the first electric push rod 39, driving the second atomizing net 38 to fine-tune the position; when the nozzle 27 sprays water, the first atomizing net 37 and the second atomizing net 38 atomize the water flow; when the holes of the two nets are aligned, the atomized water particles are the largest, and the greater the position deviation, the better the atomization degree and the smaller the particles; the greater the wind speed, the larger the atomized particles are controlled to resist the wind speed; the smaller the wind speed, the higher the atomization effect and the better the irrigation effect.
