Description

Technical Field

[0001] The present invention relates to the technical field of water collection and irrigation, and specifically to an automatic water collection and irrigation device based on photovoltaic power supply. Background Art

[0002] An automatic water collection and irrigation device is a device that uses physical principles to achieve automatic watering, and is mainly applicable to the water supply of plants in forestry or horticulture. As the economic lifeline and a major water user of the country, agriculture has long been using the traditional and backward flood irrigation method due to reasons such as ideological awareness, funds, and technology, which has greatly wasted human and material resources. Gradually promoting water collection and irrigation equipment in rural areas across China has become a mainstream in modern agriculture.

[0003] When the existing automatic water collection and irrigation device is in use, it is powered by a solar photovoltaic panel to achieve the effects of energy conservation and carbon emission reduction. However, when the existing automatic water collection and irrigation device sprays water on plants, it cannot adjust the water flow rate of the spray according to the current light intensity, which is likely to affect the growth of plants. Summary of the Invention

[0004] The purpose of the present invention is to provide an automatic water collection and irrigation device based on photovoltaic power supply to solve the problems raised in the prior art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: The automatic water collection and irrigation device based on photovoltaic power supply includes a water collection tank. A photovoltaic power generation panel is arranged on the top of the water collection tank, and an energy storage processor and a water pump are installed on the water collection tank. The input end of the water pump is connected to the bottom of the water collection tank through a suction pipe. A water delivery pipe is installed on the output end of the water pump. A flow regulator is installed on the water delivery pipe. An irrigation pipe is installed on the flow regulator. A support rod is installed on the water collection tank. A photosensitive sensor is installed on the top of the support rod. A controller is installed on the energy storage processor. A servo motor is installed on the water pump. A control gear is installed on the output end of the servo motor. An adjustment knob is arranged on the flow regulator. A rotating rod is installed on the adjustment knob. An adjustment gear is installed on the rotating rod. The adjustment gear meshes with the control gear. When it is necessary to irrigate plants, the water pump is started, and the water flow in the water collection tank can be irrigated through the irrigation pipe by the suction pipe and the water delivery pipe. At the same time, through the real-time detection of the sunlight irradiation intensity by the photosensitive sensor, the controller can control the servo motor to rotate accordingly. Thus, through the meshing action of the control gear and the adjustment gear, the rotating rod can drive the adjustment knob on the flow regulator to rotate and adjust accordingly. Furthermore, the water flow irrigation amount of the irrigation pipe can be controlled by the flow regulator according to the real-time light intensity.

[0006] As a preferred technical solution, a water collection component, a photovoltaic detection component and a photovoltaic detection and utilization component are arranged on the water collection tank, and the operation of the photovoltaic detection component provides operation drive for the photovoltaic detection and utilization component.

[0007] As a preferred technical solution, the water collection component includes a fixed rod, a mounting plate, a purification tank, a communication hole, a filter screen and a cooler;

[0008] The water collection tank is provided with a fixed rod, and there is a mounting plate on the fixed rod. The mounting plate is inclined. A photovoltaic power generation panel is fixedly installed on the mounting plate. A purification tank is installed on one side of the water collection tank. The purification tank is below the lowest position of the mounting plate. A filter screen is installed in the purification tank, and the purification tank is communicated with the water collection tank through a communication hole. A cooler is inclined and installed below the port of the communication hole close to the water collection tank. When in the water collection state, the inclined mounting plate and the photovoltaic power generation panel can guide the water flow into the purification tank, facilitating the filter screen in the purification tank to filter the collected water flow. When the water flow in the water collection tank is subjected to transpiration, the cooler can condense the rising steam, facilitating the condensed water to flow back into the water collection tank along the inclined plane, thereby reducing the transpiration loss of the collected water.

[0009] As a preferred technical solution, the photovoltaic detection component includes a driving motor, a driving wheel, a slideway, a first rotating shaft, a reciprocating lead screw, a driven wheel, a transmission belt, a sliding seat, an electric telescopic rod, a fixed frame, a second rotating shaft and a cleaning roller;

[0010] A drive motor is installed on one side of the bottom of the mounting plate away from the purification box. A drive wheel is installed on the output shaft of the drive motor. Two slideways are symmetrically opened on both sides of the mounting plate. First rotating shafts are rotatably installed at both ends of each slideway. The two first rotating shafts on the same side are connected by a reciprocating lead screw. A driven wheel is installed at the end of the first rotating shaft away from the purification box.

Second rotating shafts are rotatably installed on both sides of the fixed frame. The two second rotating shafts are connected by a cleaning roller. When it is necessary to detect the photovoltaic power generation panel, start the drive motor to drive the drive wheel to rotate. Under the belt drive of the drive wheel, the driven wheels and the transmission belt, the driven wheel can drive the reciprocating lead screw to rotate through the first rotating shaft, so that the sliding seat can reciprocate in the slideway, and the sliding seat can drive the fixed frame to move synchronously through the electric telescopic rod, which is beneficial to comprehensively detect the photovoltaic power generation panel through the vision detector during the movement of the fixed frame. When the vision detector detects stains and dirt on the photovoltaic power generation panel, the electric telescopic rod can drive the fixed frame to move downward, so that the cleaning roller can be closely attached to the photovoltaic power generation panel, which is beneficial to the cleaning roller to perform fixed-point cleaning on the photovoltaic power generation panel and ensure that the use of the photovoltaic power generation panel is not negatively affected.

[0011] As a preferred technical solution, the photovoltaic detection assembly further includes a walkway, a rotating rod, a driving tooth, a toothed plate, a transmission tooth, a driven tooth and a transmission chain;

[0012] A walkway is opened on the side of the slideway away from the photovoltaic power generation panel. A rotating rod is rotatably installed on the side of the sliding seat close to the walkway. The rotating rod penetrates through the walkway, and a driving tooth is installed on the rotating rod. A toothed plate is installed on the upper part of the side of the walkway close to the driving tooth. The toothed plate is meshed with the driving tooth. A transmission tooth is installed on the driving tooth. A driven tooth is installed at the end of the second rotating shaft away from the cleaning roller. A transmission chain is sleeved on the transmission tooth and the driven tooth on the same side. When the sliding seat moves, the sliding seat can drive the driving tooth to move synchronously through the rotating rod. Through the meshing action of the driving tooth and the toothed plate, the driving tooth rotates in the reverse direction of the moving direction. During the rotation of the driving tooth, the driving tooth can drive the transmission tooth to rotate synchronously. Through the tooth chain drive of the transmission tooth, the driven tooth and the transmission chain, the driven tooth can drive the cleaning roller to rotate through the second rotating shaft. By making the rotation direction of the cleaning roller opposite to the moving direction of the cleaning roller, the cleaning effect of the cleaning roller on the photovoltaic power generation panel can be improved.

[0013] As a preferred technical solution, a tensioner is installed on each sliding seat. The tensioner is electrically connected to the electric telescopic rod. When the electric telescopic rod contracts, it controls the tensioner to automatically tension the transmission chain, ensuring the stable operation of the tooth chain transmission of the driving gear, driven gear and transmission chain, and preventing the transmission chain from being disengaged as the fixed frame moves.

[0014] As a preferred technical solution, the photovoltaic detection utilization assembly includes a pressing plate, a fixing plate, a driving airbag, a fixing ring, a vertical rod, a sliding ring, a driven airbag, a driving shaft, a rotating ring, a transmission sleeve, a spiral slide rail and a wiping curved plate;

When the sliding seat moves reciprocally, the sliding seat can drive the pressing plate to displace synchronously. When the pressing plate moves towards the fixing plate, the pressing plate can compress the driving airbag, so that the air flow in the driving airbag can enter the driven airbag through the air pipe. The longitudinal volume expansion of the driven airbag under the action of the air flow can push the sliding ring to move up along the vertical rod. The extrusion force of the sliding ring on the spiral slide rail through the driving shaft during the upward movement can drive the transmission sleeve to drive the rotating ring to rotate, so that the rotating ring can drive the wiping curved plate to clean the photosensitive sensor. At the same time, when the pressing plate is reset, the air flow in the driven airbag can flow back to the driving airbag through the air pipe to realize the downward reset of the sliding ring, thereby realizing the steering conversion of the transmission sleeve and further realizing the two-way cleaning of the photosensitive sensor by the wiping curved plate.

[0016] As a preferred technical solution, both the driving airbag and the driven airbag are elastic telescopic airbags, which is beneficial for the driven airbag to drive the sliding ring to move downward in the reset state.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] Through the real-time detection of the intensity of sunlight irradiation by the photosensitive sensor in this application, the controller can control the servo motor to rotate accordingly. Thus, through the meshing effect of the control gear and the adjusting gear, the rotating rod can drive the adjusting knob on the flow regulator to rotate and adjust accordingly. Furthermore, the flow regulator can control the water flow irrigation volume of the irrigation pipe according to the real-time light intensity.

[0019] Through the setting of the photovoltaic detection component in this application, the visual detector can comprehensively detect the photovoltaic power generation panel, and the cleaning effect of the cleaning roller on the photovoltaic power generation panel can be improved by the opposite directions of the rotation direction and the moving direction of the cleaning roller.

[0020] Through the setting of the photovoltaic detection and utilization component in this application, by means of the reciprocating movement of the sliding seat, the transmission sleeve can be driven to drive the rotating ring to rotate, realizing the two-way cleaning of the wiping curved plate on the photosensitive sensor.

An adjustment gear 16 is installed on the rotating rod 15. The adjustment gear 16 meshes with the control gear 13. When it is necessary to irrigate the plants, the water pump 4 is started, and the water in the water collection tank 1 can be irrigated through the irrigation pipe 8 by the suction pipe 5 and the water delivery pipe 6. At the same time, through the real-time detection of the sunlight irradiation intensity by the photosensitive sensor 10, the controller 11 can control the servo motor 12 to rotate correspondingly. Thus, through the meshing action of the control gear 13 and the adjustment gear 16, the rotating rod 15 can drive the adjustment knob 14 on the flow regulator 7 to rotate and adjust correspondingly. Furthermore, the flow regulator 7 can control the water flow irrigation amount of the irrigation pipe 8 according to the real-time light intensity.

[0036] A water collection component 17, a photovoltaic detection component 18 and a photovoltaic detection and utilization component 19 are provided on the water collection tank 1.

[0038] A fixing rod 1701 is installed on the water collecting tank 1. An installation plate 1702 is provided on the fixing rod 1701. The installation plate 1702 is inclined. A photovoltaic power generation panel 2 is fixedly installed on the installation plate 1702. A purification tank 1703 is installed on one side of the water collecting tank 1. The purification tank 1703 is located below the lowest position of the installation plate 1702. A filter screen 1705 is installed in the purification tank 1703, and the purification tank 1703 is connected to the water collecting tank 1 through a communication hole 1704. A cooler 1706 is inclined and installed below the port of the communication hole 1704 close to the water collecting tank 1. When in the water collecting state, the inclined installation plate 1702 and the photovoltaic power generation panel 2 can guide the water flow into the purification tank 1703, facilitating the filter screen 1705 in the purification tank 1703 to filter the collected water flow. When the water flow in the water collecting tank 1 is affected by transpiration, the cooler 1706 can condense the rising steam, facilitating the condensed water to flow back into the water collecting tank 1 along the inclined plane, thereby reducing the transpiration loss of the collected water.

[0039] As Figures 1 - 4 and Figures 6 - 9 shown, the photovoltaic detection assembly 18 includes a driving motor 1801, a driving wheel 1802, a slideway 1803, a first rotating shaft 1804, a reciprocating lead screw 1805, a driven wheel 1806, a transmission belt 1807, a sliding seat 1808, an electric telescopic rod 1809, a fixed frame 1810, a second rotating shaft 1811 and a cleaning roller 1812;

[0040] A driving motor 1801 is installed on one side of the bottom of the mounting plate 1702 away from the purification box 1703. A driving wheel 1802 is installed on the output shaft of the driving motor 1801. Two slideways 1803 are symmetrically formed on both sides of the mounting plate 1702. First rotating shafts 1804 are rotatably installed at both ends of each slideway 1803. Two first rotating shafts 1804 on the same side are connected by a reciprocating lead screw 1805. A driven wheel 1806 is installed at the end of the first rotating shaft 1804 away from the purification box 1703. A transmission belt 1807 is sleeved on the two driven wheels 1806 and the driving wheel 1802. A sliding seat 1808 is slidably installed on the reciprocating lead screw 1805. An electric telescopic rod 1809 is installed at the upper end of the sliding seat 1808. A fixed frame 1810 is installed on the electric telescopic rod 1809. A vision detector is installed on the fixed frame 1810. Second rotating shafts 1811 are rotatably installed on both sides of the fixed frame 1810. Two second rotating shafts 1811 are connected by a cleaning roller 1812. When it is necessary to detect the photovoltaic power generation panel 2, start the driving motor 1801 to drive the driving wheel 1802 to rotate. Under the pulley transmission of the driving wheel 1802, the driven wheels 1806 and the transmission belt 1807, the driven wheel 1806 can drive the reciprocating lead screw 1805 to rotate through the first rotating shaft 1804, so that the sliding seat 1808 can reciprocate in the slideway 1803, and the sliding seat 1808 can drive the fixed frame 1810 to move synchronously through the electric telescopic rod 1809, which is beneficial to the fixed frame 1810 to comprehensively detect the photovoltaic power generation panel 2 through the vision detector during the movement. When the vision detector detects stains and dirt on the photovoltaic power generation panel 2, the electric telescopic rod 1809 can drive the fixed frame 1810 to move downward, so that the cleaning roller 1812 can be closely attached to the photovoltaic power generation panel 2, which is beneficial to the cleaning roller 1812 to perform fixed-point cleaning on the photovoltaic power generation panel 2 and ensure that the use of the photovoltaic power generation panel 2 is not negatively affected.

[0041] The photovoltaic detection assembly 18 further includes a passage 1813, a rotating rod 1814, a driving gear 1815, a toothed plate 1816, a transmission gear 1817, a driven gear 1818 and a transmission chain 1819;

[0042] On the side of the slideway 1803 away from the photovoltaic panel 2, there is an aisle 1813. On the side of the slide block 1808 close to the aisle 1813, a rotating rod 1814 is rotatably installed. The rotating rod 1814 penetrates through the aisle 1813, and a driving gear 1815 is installed on the rotating rod 1814. On the upper part of the side of the aisle 1813 close to the driving gear 1815, a toothed plate 1816 is installed. The toothed plate 1816 meshes with the driving gear 1815. A transmission gear 1817 is installed on the driving gear 1815. At the end of the second rotating shaft 1811 away from the cleaning roller 1812, a driven gear 1818 is installed. A transmission chain 1819 is sleeved on the transmission gear 1817 and the driven gear 1818 on the same side. When the slide block 1808 moves, the slide block 1808 can drive the driving gear 1815 to move synchronously through the rotating rod 1814. Through the meshing action of the driving gear 1815 and the toothed plate 1816, the driving gear 1815 rotates in the reverse direction along the moving direction. During the rotation of the driving gear 1815, the driving gear 1815 can drive the transmission gear 1817 to rotate synchronously. Then, through the chain drive of the transmission gear 1817, the driven gear 1818 and the transmission chain 1819, the driven gear 1818 can drive the cleaning roller 1812 to rotate through the second rotating shaft 1811. By making the rotation direction of the cleaning roller 1812 opposite to the moving direction of the cleaning roller 1812, the cleaning effect of the cleaning roller 1812 on the photovoltaic panel 2 can be improved.

[0043] A tensioner 1820 is installed on each of the slide blocks 1808. The tensioner 1820 is electrically connected to the electric telescopic rod 1809. When the electric telescopic rod 1809 contracts, it controls the tensioner 1820 to automatically tension the transmission chain 1819, ensuring the stable operation of the chain drive of the transmission gear, the driven gear 1818 and the transmission chain 1819, and preventing the transmission chain 1819 from being disengaged as the fixed frame 1810 moves.

[0044] As Figures 1 - 4 、 Figure 6 and Figure 9 shown, the photovoltaic detection and utilization component 19 includes a pressing plate 1901, a fixing plate 1902, a driving airbag 1903, a fixing ring 1904, a vertical rod 1905, a sliding ring 1906, a driven airbag 1907, a driving shaft 1908, a rotating ring 1909, a transmission sleeve 1910, a spiral slide rail 1911 and a wiping curved plate 1912;

[0045] A pressing plate 1901 is installed at the lower end of the sliding seat 1808. A fixing plate 1902 is installed at one side of the bottom of the mounting plate 1702 close to the driving motor 1801. The pressing plate 1901 and the fixing plate 1902 are connected by a driving airbag 1903. A fixing ring 1904 is fixedly sleeved on the support rod 9. A vertical rod 1905 is installed on the fixing ring 1904. A sliding ring 1906 is slidably installed on the vertical rod 1905. The sliding ring 1906 and the fixing ring 1904 are connected by a driven airbag 1907. The driving airbag 1903 and the driven airbag 1907 are connected by a trachea. A driving shaft 1908 is rotatably installed on the sliding ring 1906. A rotating ring 1909 is rotatably sleeved on the top of the support rod 9. A transmission sleeve 1910 is installed at the lower end of the rotating ring 1909. A spiral slide rail 1911 is provided on the inner wall of the transmission sleeve 1910. The driving shaft 1908 is inserted into the spiral slide rail 1911. Two wiping curved plates 1912 are symmetrically installed at the upper end of the rotating ring 1909. The wiping curved plates 1912 are in contact with the surface of the photosensitive sensor 10. When the sliding seat 1808 moves reciprocally, the sliding seat 1808 can drive the pressing plate 1901 to displace synchronously. When the pressing plate 1901 moves towards the fixing plate 1902, the pressing plate 1901 can compress the driving airbag 1903, so that the air flow in the driving airbag 1903 can enter the driven airbag 1907 through the trachea. The longitudinal volume expansion of the driven airbag 1907 under the action of the air flow can push the sliding ring 1906 to move upward along the vertical rod 1905. By using the pressing force of the sliding ring 1906 on the spiral slide rail 1911 through the driving shaft 1908 during the upward movement, the transmission sleeve 1910 can be driven to drive the rotating ring 1909 to rotate, so that the rotating ring 1909 can drive the wiping curved plates 1912 to clean the photosensitive sensor 10. At the same time, when the pressing plate 1901 resets, the air flow in the driven airbag 1907 can flow back into the driving airbag 1903 through the trachea to realize the downward reset of the sliding ring 1906, thereby realizing the steering conversion of the transmission sleeve 1910, and further realizing the two-way cleaning of the photosensitive sensor 10 by the wiping curved plates 1912.

[0046] Both the driving airbag 1903 and the driven airbag 1907 are elastic telescopic airbags, which is beneficial to the driven airbag 1907 driving the sliding ring 1906 to move downward in the reset state.

[0047] The working principle of the present invention:

[0048] When irrigation is required for the plants, the water pump 4 is started. The water in the water collection tank 1 can be irrigated through the irrigation pipe 8 via the water suction pipe 5 and the water delivery pipe 6. Meanwhile, through the real-time detection of the intensity of sunlight irradiation by the photosensitive sensor 10, the controller 11 can control the servo motor 12 to rotate accordingly. Thus, through the meshing action of the control gear 13 and the adjusting gear 16, the rotating rod 15 can drive the adjusting knob 14 on the flow regulator 7 to rotate and adjust accordingly. Furthermore, the flow regulator 7 can control the water flow irrigation volume of the irrigation pipe 8 according to the real-time light intensity.

[0049] When the photovoltaic power generation panel 2 needs to be detected, the driving motor 1801 is started, and the driving motor 1801 drives the driving wheel 1802 to rotate. Under the belt drive of the driving wheel 1802, the driven wheel 1806 and the transmission belt 1807, the driven wheel 1806 can drive the reciprocating lead screw 1805 to rotate through the first rotating shaft 1804. Thus, the sliding seat 1808 can reciprocate in the slideway 1803, enabling the sliding seat 1808 to drive the fixed frame 1810 to displace synchronously through the electric telescopic rod 18, which is conducive to the fixed frame 1810 comprehensively detecting the photovoltaic power generation panel 2 through the vision detector during the movement. When the vision detector detects stains and dirt on the photovoltaic power generation panel 2, the electric telescopic rod 1809 can drive the fixed frame 1810 to move downward, enabling the cleaning roller 1812 to closely adhere to the photovoltaic power generation panel 2, which is conducive to the cleaning roller 1812 performing targeted cleaning on the photovoltaic power generation panel 2 and ensuring that the use of the photovoltaic power generation panel 2 is not negatively affected.

[0050] When the sliding seat 1808 moves, the sliding seat 1808 can drive the driving gear 1815 to move synchronously through the rotating rod 1814. Through the meshing action of the driving gear 1815 and the toothed plate 1816, the driving gear 1815 rotates in the reverse direction along the moving direction. During the rotation of the driving gear 1815, it can drive the transmission gear 1817 to rotate synchronously. Through the gear chain drive of the transmission gear 1817, the driven gear 1818 and the transmission chain 1819, the driven gear 1818 can drive the cleaning roller 1812 to rotate through the second rotating shaft 1811. By making the rotation direction of the cleaning roller 1812 opposite to the moving direction of the cleaning roller 1812, the cleaning effect of the cleaning roller 1812 on the photovoltaic power generation panel 2 can be improved.

[0051] When the sliding seat 1808 reciprocates, the sliding seat 1808 can drive the extrusion plate 1901 to move synchronously. When the extrusion plate 1901 moves towards the fixed plate 1902, the extrusion plate 1901 can compress the driving airbag 1903, so that the air flow in the driving airbag 1903 can enter the driven airbag 1907 through the air pipe. The longitudinal volume expansion of the driven airbag 1907 under the action of the air flow can push the sliding ring 1906 to move upward along the vertical rod 1905. The extrusion force of the sliding ring 1906 on the spiral slide rail 1911 during the upward movement through the drive shaft 1908 can drive the transmission sleeve 1910 to drive the rotating ring 1909 to rotate, so that the rotating ring 1909 can drive the wiping curved plate 1912 to clean the photosensitive sensor 10. At the same time, when the extrusion plate 1901 resets, the air flow in the driven airbag 1907 can flow back to the driving airbag 1903 through the air pipe, realizing the downward reset of the sliding ring 1906, thereby enabling the steering conversion of the transmission sleeve 1910, and further enabling the two-way cleaning of the photosensitive sensor 10 by the wiping curved plate 1912.
