Description

Technical Field

[0001] This utility model specifically relates to the field of agricultural irrigation technology, and more specifically to a water-saving irrigation sprayer that utilizes photovoltaic power generation. Background Technology

[0002] An irrigation sprinkler is an irrigation device used in agriculture, horticulture, landscaping and other fields. Its main function is to disperse and spray water in a certain way to the area that needs irrigation in order to meet the water requirements of plant growth. In order to meet the purpose of water collection, most irrigation sprinklers are equipped with nozzles at the end, and the water supply is controlled by controlling the amount of water sprayed from the nozzles.

[0003] Since most irrigation sprinkler pumps are powered by electricity, they need to be powered by an outdoor power source when used outdoors. However, this method of power supply cannot provide power for extended periods. To ensure long-term power supply, people use photovoltaic power generation to power the water pumps.

[0004] However, in practice, it has been noted that due to the limited top area of ​​the irrigation sprinkler, the power generated by the photovoltaic panels on top of the sprinkler alone is insufficient to replenish the battery. The energy consumed is greater than the energy required for charging, and it is still insufficient to meet the power supply for the water pump to work for a long time. Increasing the area of ​​the photovoltaic panels would increase the area of ​​the irrigation sprinkler, which would affect the carrying and transportation of the irrigation sprinkler and make it very inconvenient. Utility Model Content

[0005] The purpose of this invention is to provide a water-saving irrigation sprinkler that utilizes photovoltaic power generation. Through the cooperation of a fan-shaped photovoltaic panel and a rotating shaft, the photovoltaic panel can be unfolded, increasing the area exposed to sunlight and thus improving power generation. Furthermore, it reduces the size when folded up, making it easy to carry. This addresses the technical problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A water-saving irrigation sprinkler that utilizes photovoltaic power generation includes a housing, with an integral partition on the inner side of the housing. An irrigation water pump and an inverter are respectively installed on both sides of the partition. The irrigation water pump is fixedly connected to the housing, while the inverter is fixedly connected to the partition.

[0008] The partition is also equipped with a battery on the side near the inverter, and the battery is fixedly connected to the casing.

[0009] A support shaft is fixedly connected to the top of the outer casing. Photovoltaic rotating blades are movably connected to the support shaft in a rectangular array. An end cover and a locking nut are also installed on the top of the support shaft.

[0010] As a further technical solution of this utility model, each of the photovoltaic rotating blades includes a fan-shaped support shell, an end shaft plate integrally provided at the end of the support shell, and an installation bearing is interference-fitted in the end shaft plate. The support shell is movably connected to the support shaft through the installation bearing.

[0011] As a further technical solution of this utility model, a photovoltaic power generation panel is embedded in the top of the supporting shell, and a supporting baffle is integrally provided on both sides of the supporting shell near the end shaft plate.

[0012] As a further technical solution of this utility model, the support shaft includes a shaft rod fixedly connected to the top of the outer shell, and the top of the shaft rod is provided with a hexagonal bracket and a threaded post in sequence, and the hexagonal bracket and the threaded post are respectively integrally set with the shaft rod.

[0013] As a further technical solution of this utility model, the shaft passes through the end plate and is interference-fitted with the inner ring of the bearing, and the end of the shaft with a threaded post passes through the end cover and the locking nut respectively, wherein the locking nut and the threaded post are threadedly engaged.

[0014] As a further technical solution of this utility model, the inner side of the end cover is provided with a hexagonal through hole corresponding to the hexagonal card seat, and the hexagonal card seat is inserted into the hexagonal through hole, and the bottom of the end cover is in contact with the uppermost end shaft plate.

[0015] As a further technical solution of this utility model, the inlet and outlet of the irrigation pump are respectively fixedly connected with an outlet pipe and an inlet pipe by bolts, and the ends of the outlet pipe and the inlet pipe away from the irrigation pump extend through the outer shell to both sides of the outer shell.

[0016] As a further technical solution of this utility model, the supporting shell has two symmetrically fitted waterproof shells, and the edge of the waterproof shell is integrally provided with a semi-circular protrusion, and the outer side of the supporting shell is snapped with an outer clamp.

[0017] As a further technical solution of this utility model, the outer clamp includes a C-shaped metal clamp that engages with a semi-circular protrusion on the outside of the supporting shell. A hollow tube is fixedly connected to the end of the C-shaped metal clamp. Both ends of the hollow tube are integrally provided with threaded heads, and the bottom of the hollow tube is provided with spray nozzles in a rectangular array.

[0018] As a further technical solution of this utility model, an insulating base is fixedly connected to the inner side of the outer shell, and terminals are symmetrically fixedly connected to the side of the insulating base.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This invention utilizes multiple fan-shaped photovoltaic rotating blades, which, when unfolded, approach a circular shape, increasing the number of blades and ensuring they do not interfere with each other, thereby increasing power generation and guaranteeing a stable power supply to the irrigation pump over a long period. The multiple photovoltaic rotating blades are connected together by a support shaft, allowing them to rotate and unfold or retract around this shaft. Unfolding increases the area exposed to sunlight, while retracting facilitates portability. Each blade has a hollow tube at its end for drip irrigation in the vicinity, further enhancing usability. An inner partition separates the irrigation pump from the inverter and battery, preventing leakage during water supply that could cause short circuits in the inverter or battery, thus improving safety. An insulating base and terminal block on one side of the partition allow excess power to be transferred to the grid, further enhancing functionality. Attached Figure Description

[0035] Please see Figure 1-11 This utility model provides a water-saving irrigation sprayer that utilizes photovoltaic power generation, including a housing 1.

[0036] A battery 11 is also provided on the side of the partition near the inverter 10, and the battery 11 is fixedly connected to the outer casing 1, so as to store excess electrical energy through the battery.

[0037] A support shaft 4 is fixedly connected to the top of the outer casing 1. Photovoltaic rotating blades 5 are movably connected to the support shaft 4 in a rectangular array. An end cover 6 and a locking nut 7 are also installed on the top of the support shaft 4. The position of the photovoltaic rotating blades 5 is limited by the end cover 6 and the locking nut 7.

[0038] In this embodiment, each of the photovoltaic rotating blades 5 includes a fan-shaped support shell 51. The end of the support shell 51 is integrally provided with an end shaft plate 54, and an installation bearing 55 is interference-fitted in the end shaft plate 54. The support shell 51 is movably connected to the support shaft 4 through the installation bearing 55. The fan-shaped photovoltaic rotating blades 5 ensure that each photovoltaic rotating blade 5 does not interfere with each other.

[0039] Furthermore, a photovoltaic power generation panel 52 is embedded in the top of the supporting shell 51, and a supporting baffle 53 is integrally provided on both sides of the supporting shell 51 near the end shaft plate 54.

[0040] In this embodiment, the support shaft 4 includes a shaft 41 fixedly connected to the top of the outer casing 1. The top of the shaft 41 is provided with a hexagonal bracket 42 and a threaded post 43 in sequence, and the hexagonal bracket 42 and the threaded post 43 are respectively integrally formed with the shaft 41.

[0041] More specifically, the shaft 41 passes through the end plate 54 and is interference-fitted with the inner ring of the bearing 55. The end of the shaft 41 with the threaded post 43 passes through the end cover 6 and the locking nut 7 respectively, wherein the locking nut 7 and the threaded post 43 are threadedly engaged.

[0042] Furthermore, the inner side of the end cover 6 is provided with a hexagonal through hole corresponding to the hexagonal bracket 42, and the hexagonal bracket 42 is inserted into the hexagonal through hole. The bottom of the end cover 6 is in contact with the uppermost end shaft plate 54.

[0043] In this embodiment, the inlet and outlet of the irrigation pump 9 are respectively fixedly connected with a water outlet pipe 3 and a water inlet pipe 8 by bolts, and the ends of the water outlet pipe 3 and the water inlet pipe 8 away from the irrigation pump 9 respectively extend through the outer casing 1 to both sides of the outer casing 1.

[0044] In this embodiment, the supporting shell 51 has two symmetrically fitted waterproof shells, and the edge of the waterproof shell is integrally provided with a semi-circular protrusion. The outer side of the supporting shell 51 is snapped with an outer clamp 13, which fixes the symmetrically arranged edge position of the supporting shell 51.

[0045] More specifically, the outer clamp 13 includes a C-shaped metal clamp 131 that engages with a semi-circular protrusion on the outside of the supporting shell 51. A hollow tube 132 is fixedly connected to the end of the C-shaped metal clamp 131. Both ends of the hollow tube 132 are integrally provided with threaded heads 133, and the bottom of the hollow tube 132 is provided with spray nozzles 134 in a rectangular array.

[0046] In this embodiment, an insulating base 12 is fixedly connected to the inner side of the outer casing 1, and terminals 121 are symmetrically fixedly connected to the side of the insulating base 12. Each terminal 121 is electrically connected to the inverter 10 through a wire.

[0047] By adopting the above technical solution, the locking nut 7 is loosened, and then the support shell 51 is rotated. The support shell 51, which is arranged in a fan shape, is arranged in a ring array after unfolding. Multiple support shells 51 are arranged in a ring array and are staggered. The end shaft plates 54 arranged on the side of adjacent support shells 51 fit together to provide support. By increasing the light-receiving area of ​​the photovoltaic power generation module, the power generation of the irrigation sprinkler is increased.

[0048] In this embodiment, each of the supporting shells 51 has a groove at its bottom, in which a wire is placed. One end of the wire passes through the supporting shell 51 and is electrically connected to the photovoltaic power generation panel 52, and the other end passes through the shell 1 and is electrically connected to the input terminal of the inverter 10.

[0049] More specifically, the output terminal of the inverter 10 is electrically connected to the battery 11 via a wire.

[0052] In this embodiment, baffles 2 are provided on both sides of the outer casing 1, which are parallel to the partition. The baffles 2 shield the two sides of the outer casing 1, thus protecting the water pump 9, inverter 10 and battery 11.

[0053] In this embodiment, the baffle 2 is also embedded with observation windows in a rectangular array, through which workers can clearly observe the working status of the irrigation pump 9, inverter 10 and battery 11.

[0054] The working principle of this utility model is as follows: When in use, the irrigation sprinkler is first moved to the designated position, and then the inlet pipe 8 is connected to the water supply tank, the outlet pipe 3 and the nozzle through the pipeline. Then, the support shell 51 is rotated, and multiple support shells 51 are arranged in a ring array and staggered. Each support shell 51 is arranged in a fan shape, so the support shells 51 will not affect each other after being unfolded. The photovoltaic power generation panel 52 after unfolding increases the area exposed to sunlight, thereby increasing the power generation. The photovoltaic power generation panel 52 sends the current to the inverter 10, and the inverter 10 stores the electrical energy in the battery 11. Then, the electrical energy in the battery 11 powers the irrigation water pump 9. The irrigation water pump 9 works with the outlet pipe 3 and the inlet pipe 8 to send water into the nozzle. The amount of water used is controlled by the nozzle.

[0055] After the supporting shell 51 is unfolded, the C-shaped metal hoop 131 on the outside of each supporting shell 51 is also unfolded. Then, depending on the usage, the pipe is connected to the water outlet pipe 3 through a T-shaped pipe, and part of the water source in the water outlet pipe 3 is introduced into the hollow pipe 132. Then, the water is discharged through the spray nozzle 134 set at the bottom of the hollow pipe 132 to realize close-range drip irrigation.

[0056] Connect the end of the conductor to terminal 121, and connect terminal 121 to the power grid through the conductor. Excess electrical energy is sent into the power grid through terminal 121 and the conductor.
