Description

Technical Field

[0001] The present invention relates to the field of irrigation equipment, and particularly to a solar ecological agricultural water-saving irrigation equipment. Background Art

[0002] Agricultural irrigation equipment is machinery and systems used for farmland irrigation, aiming to provide an appropriate amount of water to meet the needs of crop growth while minimizing water resource waste.

[0003] In existing agricultural irrigation equipment, after the sprinkler is installed in the farmland, the water pump pumps water into the sprinkler, and the water is sprayed onto the crops through the sprinkler. However, due to the fixed spraying direction and range of the sprinkler, when the sprinkler is installed at the edge of the farmland or in a farmland with uneven crop distribution for water spraying irrigation, the water sprayed onto the unplanted crop area will be wasted, reducing the utilization rate of water resources and not meeting the requirements of water-saving agriculture.

[0004] Therefore, a solar ecological agricultural water-saving irrigation equipment has now been developed, which can block the water sprayed onto the unplanted crop area and recycle the blocked water to avoid water resource waste. Summary of the Invention

[0005] In order to overcome the defect that in existing agricultural irrigation equipment, when the sprinkler is installed at the edge of the farmland or in a farmland with uneven crop distribution for water spraying irrigation, the water sprayed onto the unplanted crop area will be wasted, the present invention provides a solar ecological agricultural water-saving irrigation equipment that can block the water sprayed onto the unplanted crop area and recycle the blocked water to avoid water resource waste.

[0006] The technical solution is as follows: A solar ecological agricultural water-saving irrigation equipment includes a bottom plate, a water tank, ground plugs, and a spraying mechanism. The water tank is connected to the lower side of the bottom plate, and ground plugs are connected to the lower sides of the left and right parts of the water tank. A spraying mechanism capable of irrigating the farmland is provided on the bottom plate.

[0007] As an improvement of the above solution, a water inlet groove is opened on the bottom plate.

[0008] As an improvement to the above solution, the spraying mechanism includes an enclosure frame, a central pump, a flow pipe, a tapered pipe, a neck frame, a shoulder frame, a nozzle, an enclosure seat, a circular ring, and a plate wall. An enclosure frame is connected to the upper side of the middle part of the bottom plate. A central pump is connected to the middle part of the enclosure frame. The water suction pipe of the central pump passes through the bottom plate and contacts the water tank. A flow pipe is connected to the upper side of the central pump. A tapered pipe is rotatably connected to the upper side of the flow pipe. A neck frame is connected to the upper side of the enclosure frame. The tapered pipe passes through the neck frame. Shoulder frames are connected to the upper sides of the left and right parts of the neck frame. A nozzle is connected to the upper side of the tapered pipe. An enclosure seat is connected between the shoulder frames. A plurality of circular rings are rotatably connected to the enclosure seat. Plate walls are connected to the circular rings. The nozzle is located inside the plate walls. According to the distribution position of the crops, the plate walls in the direction where no crops are planted are rotated to the vertical state, and the plate walls in the direction where crops are planted are rotated to the horizontal state, driving the rotation of the circular rings on the enclosure seat. The shoulder frames support the enclosure seat, so that the water sprayed by the nozzles in the direction where no crops are planted is sprayed onto the plate walls and then falls from the plate walls to the bottom plate, and enters the water tank through the water inlet groove on the bottom plate.

[0009] As an improvement to the above solution, it further includes a photovoltaic mechanism. The photovoltaic mechanism includes side frames, torsion springs, lateral motors, protective cylinders, lead screws, central shafts, V-shaped frames, compression springs, clamping clips, photovoltaic panels, and quadrant sensors. Two left and right side frames are connected to the upper sides of the front and rear parts of the bottom plate respectively. Support frames are provided on the upper sides of the left and right parts of the bottom plate. Lateral motors are connected to the support frames. Protective cylinders are connected to the left and right parts of the enclosure frame. The protective cylinders are located outside the adjacent lateral motors. Lead screws are connected to the output shafts of the lateral motors. Central shafts are threadedly connected to the lead screws. The central shafts are slidably connected to the enclosure frame. V-shaped frames are connected to the central shafts. Clamping clips are slidably connected to the front and rear parts of the V-shaped frames. Compression springs are connected between the clamping clips and the connected V-shaped frames. Photovoltaic panels are rotatably connected between the horizontally adjacent two side frames. Torsion springs are connected between the side frames and the connected photovoltaic panels. A plurality of quadrant sensors are connected to the upper sides of the photovoltaic panels. The quadrant sensors are connected to the lateral motors through wires. When the position of the sun moves westward, the quadrant sensors control the lateral motors to start, causing the lead screws to rotate and controlling the central shafts to move upward, so that the V-shaped frames move upward. When the V-shaped frames move upward, they push the photovoltaic panels to rotate on the side frames, and the torsion springs deform. When the sun moves to the due middle position, the photovoltaic panels rotate to the horizontal.

[0010] As an improvement to the above solution, it further includes a valve-changing mechanism. The valve-changing mechanism includes side arms, cam wheels, ball valves, and handles. Side arms are connected to the mutually adjacent sides of the central shafts. A ball valve is rotatably connected to the upper inner part of the flow pipe. Cam wheels are connected to the left and right sides of the ball valve. The cam wheels are meshed with the adjacent side arms. A handle is connected between the cam wheels. When the central shafts move upward, they drive the side arms to move upward, causing the side arms to push the cam wheels to rotate, driving the ball valve to rotate, and making the opening of the ball valve larger. When the central shafts move downward, they drive the side arms to move downward, making the opening of the ball valve smaller.

[0011] As an improvement of the above scheme, a cleaning mechanism is also included, which includes a side seat, a rodless cylinder and a magnetic brush. Side seats are connected to the left and right sides of the photovoltaic panel, and a rodless cylinder is connected between two laterally adjacent side seats. The sliders of the rodless cylinders are connected to magnetic brushes. A dustpan is provided on the upper right side of the photovoltaic panel. The rodless cylinder on the side seat is started to move the magnetic brush to the right on the photovoltaic panel, so that the dust on the photovoltaic panel is adsorbed onto the magnetic brush.

[0012] As an improvement of the above scheme, it also includes a rotating mechanism, which includes a front motor, a rotating drum, a belt and a guide frame. The front motor is connected to the front side of the lower part of the frame, and the rotating drum is connected to the output shaft of the front motor. A belt is wound around the rotating drum and the conical tube through a pulley. The guide frame is rotatably connected between the upper side of the rotating drum and the conical tube. Starting the front motor drives the rotating drum to rotate on the guide frame, and the conical tube is rotated through the belt transmission, thereby driving the nozzle to rotate.

[0013] As an improvement of the above scheme, it also includes an insect removal mechanism, which includes a cylindrical frame, a charged pole, an attraction lamp and a collecting tray. The upper side of the protective tube is connected to the collecting tray, the upper side of the collecting tray is connected to the cylindrical frame, the screw rods pass through adjacent cylindrical frames, a plurality of charged poles are connected to the cylindrical frames, and the upper part of the cylindrical frames is connected to the attraction lamps. The charged poles on the cylindrical frames are energized, and then the attraction lamps are turned on to attract pests in the farmland. When the pests touch the charged poles, they are electrocuted and fall into the collecting tray.

[0014] The beneficial effects of the present invention are: 1. The present invention rotates the board wall in the direction where crops are not planted to a vertical state, and rotates the board wall in the direction where crops are planted to a horizontal state, so that the water sprayed from the nozzle in the direction where crops are not planted is sprayed onto the board wall, and then falls from the board wall to the bottom plate and enters the water tank, thereby achieving the effect of blocking the water sprayed to the area where crops are not planted, and recovering the blocked water, thereby avoiding waste of water resources.

[0015] 2. When the direction of sunlight deviates, the lateral motor of the present invention is started, and the central axis is moved downward through the screw rod, so that the clip drives the photovoltaic panel to rotate in one direction toward the sunlight, thereby achieving the effect of being able to adjust the angle of the photovoltaic panel and improving the utilization rate of solar energy.

[0016] 3. The present invention drives the side arms upward while the central axis moves upward, so that the side arms push the concave wheels to rotate, drive the ball valve to rotate, and make the ball valve opening larger. The central axis moves downward while the side arms move downward, so that the ball valve opening becomes smaller, thereby achieving the effect of being able to adjust the amount of irrigation water according to light and avoiding waste of water resources.

[0017] 4. By starting the rodless cylinder on the side seat, the magnetic plate brush moves to the right on the photovoltaic panel, so that the dust on the photovoltaic panel is adsorbed onto the magnetic plate brush, achieving the effect of being able to clean the photovoltaic panel and avoiding affecting the power generation efficiency of the photovoltaic panel.

[0018] 5. By starting the front motor, the rotating cylinder is driven to rotate on the guide frame, and the tapered tube is rotated through belt drive, thereby driving the nozzle to rotate, achieving the effect of being able to rotate the nozzle to facilitate adjusting the spraying range of the nozzle.

Detailed implementation manners

[0029] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0030] A solar ecological agricultural water-saving irrigation device, as Figure 1 and Figure 2 shown, includes a bottom plate 0, a water tank 1, a floor plug 2 and a spraying mechanism 3. A water tank 1 is connected to the lower side of the bottom plate 0. A water inlet groove is opened on the bottom plate 0 to facilitate water collection. Floor plugs 2 are connected to the lower sides of the left and right parts of the water tank 1. A spraying mechanism 3 is provided on the bottom plate 0.

[0031] As Figure 1 and Figure 3 shown, the spraying mechanism 3 includes an enclosure frame 30, a central pump 31, a flow pipe 32, a tapered pipe 33, a neck frame 34, a shoulder frame 340, a nozzle 35, an enclosure seat 36, a ring 37 and a plate wall 38. An enclosure frame 30 is connected to the upper side of the middle part of the bottom plate 0. A central pump 31 is connected to the middle part of the enclosure frame 30. The water suction pipe of the central pump 31 passes through the bottom plate 0 and contacts the water tank 1. A flow pipe 32 is connected to the upper side of the central pump 31. A tapered pipe 33 is rotatably connected to the upper side of the flow pipe 32. A neck frame 34 is connected to the upper side of the enclosure frame 30. The tapered pipe 33 passes through the neck frame 34. Shoulder frames 340 are connected to the upper sides of the left and right parts of the neck frame 34. A nozzle 35 is connected to the upper side of the tapered pipe 33. An enclosure seat 36 is connected between the shoulder frames 340. Sixteen rings 37 are rotatably connected to the enclosure seat 36. Plate walls 38 are connected to the rings 37. The nozzle 35 is located inside the plate walls 38.

[0032] When using the present invention, first insert the ground plug 2 into the farmland so that the water tank 1 and the bottom plate 0 are fixed in the farmland. Then connect the water pipe to the water tank 1 to supply water to the water tank 1. When it is necessary to water the crops, start the central pump 31 on the surrounding frame 30 to pump the water in the water tank 1 into the flow pipe 32 by the central pump 31, then pass through the tapered pipe 33 from the flow pipe 32, and finally spray from the nozzle 35 to the farmland to irrigate the crops. When irrigating the farmland, according to the distribution position of the crops, the plate wall 38 in the direction where no crops are planted can be rotated to the vertical state, and the plate wall 38 in the direction where crops are planted can be rotated to the horizontal state, driving the rotation of the ring 37 on the surrounding seat 36. The shoulder frame 340 supports the surrounding seat 36, so that the water sprayed from the nozzle 35 in the direction where no crops are planted is sprayed onto the plate wall 38, and then falls from the plate wall 38 to the bottom plate 0, and enters the water tank 1 through the water inlet groove on the bottom plate 0. Thus, it plays a role in blocking the water sprayed to the area where no crops are planted and recovering the blocked water, avoiding waste of water resources.

[0033] As Figure 1 , Figure 4 and Figure 5 shown, it further includes a photovoltaic mechanism 4. The photovoltaic mechanism 4 includes side frames 40, torsion springs 401, lateral motors 41, protective cylinders 42, lead screws 43, central shafts 44, V-shaped frames 45, compression springs 46, clip fasteners 47, photovoltaic panels 48 and quadrant sensors 49. On the upper sides of the front and rear parts of the bottom plate 0, two left and right side frames 40 are respectively connected. On the upper sides of the left and right parts of the bottom plate 0, support frames are respectively provided, and lateral motors 41 are connected to the support frames. On the left and right parts of the surrounding frame 30, protective cylinders 42 are respectively connected. The protective cylinders 42 are all located outside the adjacent lateral motors 41. On the output shafts of the lateral motors 41, lead screws 43 are respectively connected. On the lead screws 43, central shafts 44 are threadedly connected. The central shafts 44 are all slidably connected to the surrounding frame 30. On the central shafts 44, V-shaped frames 45 are respectively connected. On the front and rear parts of the V-shaped frames 45, clip fasteners 47 are slidably connected. Between the clip fasteners 47 and the connected V-shaped frames 45, compression springs 46 are respectively connected. Between the laterally adjacent two side frames 40, photovoltaic panels 48 are respectively rotatably connected. Between the side frames 40 and the connected photovoltaic panels 48, torsion springs 401 are respectively connected. On the upper sides of the photovoltaic panels 48, four quadrant sensors 49 are respectively connected. The quadrant sensors 49 are all connected to the lateral motors 41 through wires.

[0034] Using the photovoltaic mechanism 4 of this device can save electrical energy. Connect the photovoltaic panel 48 to the energy storage device through wires, so that the photovoltaic panel 48 converts solar energy into electrical energy and stores it in the energy storage device, and then supplies power to this farmland irrigation system through the energy storage device. The casing 42 is used to shield the lateral motor 41, and the support frame supports the lateral motor 41 to prevent the lateral motor 41 from getting water. When the bottom plate 0 is fixed in the farmland, the photovoltaic panel 48 faces the direction where the sun rises. The four-quadrant sensor 49 senses the position of the sun. When the position of the sun moves westward, the four-quadrant sensor 49 controls the lateral motor 41 to start, making the lead screw 43 rotate and controlling the central shaft 44 to move upward, so that the V-shaped frame 45 moves upward. When the V-shaped frame 45 moves upward, it pushes the photovoltaic panel 48 to rotate on the side frame 40, and the torsion spring 401 deforms. When the sun moves to the due position, the photovoltaic panel 48 rotates to the horizontal. When the photovoltaic panel 48 rotates to the horizontal, the photovoltaic panel 48 is clamped and matched with the clip 47. When the sunlight shifts westward, the lateral motor 41 starts, and the central shaft 44 moves downward through the lead screw 43, so that the clip 47 drives the photovoltaic panel 48 to rotate westward. The photovoltaic panel 48 pushes the clip 47 to move, and the compression spring 46 contracts, thus playing a role in being able to adjust the angle of the photovoltaic panel 48 and improving the utilization rate of solar energy. When the photovoltaic panel 48 rotates westward to the limit, the V-shaped frame 45 continues to move downward, so that the clip 47 no longer engages with the photovoltaic panel 48. Through the rebound of the compression spring 46, the clip 47 is driven to reset, and then through the restoration of the torsion spring 401, the photovoltaic panel 48 is driven to rotate and reset.

[0035] As Figure 1 and Figure 6 shown, it also includes a variable valve mechanism 5. The variable valve mechanism 5 includes a side arm 51, a cam 52, a ball valve 53 and a handle 54. Side arms 51 are connected to the mutually close sides of the central shaft 44. A ball valve 53 is rotatably connected to the upper part inside the flow pipe 32. Cam 52s are connected to both the left and right sides of the ball valve 53, and the cam 52s are respectively engaged with the adjacent side arms 51. A handle 54 is connected between the cam 52s.

[0036] Using the variable valve mechanism 5 of this device can adjust the irrigation water volume according to the light. When the sun moves to the due position, the temperature rises. While the central shaft 44 moves upward, it drives the side arm 51 to move upward, so that the side arm 51 pushes the cam 52 to rotate, driving the ball valve 53 to rotate, making the opening of the ball valve 53 become larger. While the central shaft 44 moves downward, it drives the side arm 51 to move downward, making the opening of the ball valve 53 become smaller, thus playing a role in being able to adjust the irrigation water volume according to the light and avoiding waste of water resources. When it is necessary to adjust the opening of the ball valve 53 separately, the side arm 51 can be disengaged from the cam 52, and then the cam 52 is rotated through the handle 54, and further drives the ball valve 53 to rotate.

[0037] As Figure 1 and Figure 7As shown, a cleaning mechanism 6 is also included, which includes a side seat 61, a rodless cylinder 62 and a magnetic brush 63. The left and right sides of the photovoltaic panel 48 are connected to the side seats 61, and the two side seats 61 adjacent to each other in the horizontal direction are connected to the rodless cylinder 62. The slider of the rodless cylinder 62 is connected to the magnetic brush 63, and a dustpan is provided on the upper right side of the photovoltaic panel 48.

[0038] The cleaning mechanism 6 of the device can be used to clean the photovoltaic panel 48. The rodless cylinder 62 on the side seat 61 is started to move the magnetic brush 63 to the right on the photovoltaic panel 48, so that the dust on the photovoltaic panel 48 is adsorbed onto the magnetic brush 63. After the magnetic brush 63 moves to the dustpan, the power of the magnetic brush 63 is cut off, so that the dust on the magnetic brush 63 falls into the dustpan. When there is a lot of dust in the dustpan, the dustpan is removed to clean the dust, thereby cleaning the photovoltaic panel 48 and avoiding affecting the power generation efficiency of the photovoltaic panel 48.

[0039] like Figure 1 and Figure 8 As shown, it also includes a rotating mechanism 7, which includes a front motor 71, a rotating drum 72, a belt 73 and a guide frame 74. The front motor 71 is connected to the front side of the lower part of the frame 30, and the rotating drum 72 is connected to the output shaft of the front motor 71. The belt 73 is wound around the rotating drum 72 and the cone tube 33 through a pulley, and the guide frame 74 is rotatably connected between the upper side of the rotating drum 72 and the cone tube 33.

[0040] By using the rotating mechanism 7 of the device, the nozzle 35 can be rotated. The front motor 71 is started to drive the rotating drum 72 to rotate on the guide frame 74. The cone tube 33 is rotated through the belt 73, and then the nozzle 35 is driven to rotate, thereby enabling the nozzle 35 to rotate so as to adjust the spraying range of the nozzle 35.

[0041] like Figure 1 and Figure 9 As shown, it also includes an insect removal mechanism 8, which includes a cylindrical frame 81, a charged rod 82, an attraction lamp 83 and a collecting plate 84. The upper side of the protective tube 42 is connected to the collecting plate 84, the upper side of the collecting plate 84 is connected to the cylindrical frame 81, the screw rod 43 passes through the adjacent cylindrical frame 81, a plurality of charged rods 82 are connected to the cylindrical frame 81, and the upper part of the cylindrical frame 81 is connected to the attraction lamp 83.

[0042] The insect removal mechanism 8 of the device can reduce pests in farmland. At night, the charged rod 82 on the cylindrical frame 81 is energized, and then the attraction lamp 83 is turned on to attract the pests in the farmland. When the pests touch the charged rod 82, they are electrocuted and fall into the collection tray 84, thereby reducing the pests in the farmland and improving the growth quality of crops.

[0043] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
