Description

Technical Field

[0001] The invention relates to the technical field of irrigation equipment, and in particular to an agriculture and forestry photovoltaic water-saving irrigation device. Background Art

[0002] In the agricultural and forestry planting of vegetables, flowers, fruits and vegetables, irrigation devices consisting of water pumps and pipelines are used to irrigate crops. In order to reduce the power consumption in irrigation, photovoltaic cells are used to generate electricity to reduce power consumption.

[0003] During the day, the sunlight at noon is the strongest and the photovoltaic cells are most efficient. The photovoltaic cells generate electricity at noon to drive the main pump for pumping irrigation operations. However, since the sunlight at noon is the strongest, the evaporation during irrigation in the middle is also the strongest, resulting in large evaporation losses in irrigation. Although electricity is saved, the water consumption increases further, and the evaporation of irrigation water leads to a large amount of waste. Summary of the invention

[0004] The disclosed embodiment relates to an agricultural and forestry photovoltaic water-saving irrigation device, wherein a middle scissor bracket supports an upper box body to move upward, and an inner corrugated telescopic box body simultaneously extends upward to expand the internal volume, utilizes the power generation of the midday sunlight to store water, and the inner corrugated telescopic box body temporarily stores irrigation water, so that irrigation is not required at noon, thereby reducing evaporation losses during noon irrigation and achieving the purpose of water saving, thereby avoiding the situation in which the midday sunlight is strong and the power generation is large, but the evaporation is also strong, and the evaporation losses are large due to relying on solar energy for irrigation, and a large amount of water is wasted due to evaporation. As the afternoon sun weakens, the power generation of the side photovoltaic panels will also decrease, and the power of the main pump will also decrease and gradually shut down. The main pump machine and the upper counterweight frame generate downward pressure on the inner corrugated telescopic box body under gravity, thereby increasing the water outlet speed of the lower outlet pipe.

During storage, when the height of the middle scissor fork bracket 102 is reduced, the middle scissor fork bracket 102 will synchronously descend, and in the process of the middle part of the middle scissor fork bracket 102 descending to the lowest part, the middle part of the middle scissor fork bracket 102 presses the side limit support plate 103 to move down, and the side limit support plate 103 moves down and contacts the ground, so as to achieve support and fixation during storage.

[0026] The working principle of this embodiment is as follows: the main frame 1 moves along the ground through the lower roller 106, the main frame 1 moves to the designated location, the lower outlet pipe 202 is connected to the irrigation pipeline, the upper inlet pipe 203 is connected to the well pool, the upper electric screw 105 is driven to rotate by the motor, the upper electric screw 105 drives the upper connecting frame 104 to move axially, the upper connecting frame 104 drives the upper two ends of the middle scissor bracket 102 to move closer, the height of the middle scissor bracket 102 is increased, the middle scissor bracket 102 synchronously supports the upper box 201 to move upward, the space between the upper box 201 and the lower box 2 is expanded, the extension space of the inner corrugated telescopic box 4 is expanded, the side photovoltaic panel 3 is expanded outward to a horizontal state, and the side photovoltaic panel 3 is adjusted with the first connecting rotating frame 301 to ensure that the photovoltaic panel 3 on the direct sunlight side reaches the maximum From the efficiency perspective, the bottom tip of the lower support frame 304 is inserted into the ground, and the upper connecting bracket 303 and the lower supporting frame 304 support and fix the side photovoltaic panel 3. The sliding extension length between the upper connecting bracket 303 and the lower supporting frame 304 adapts to the change in the inclination angle of the side photovoltaic panel 3. The side photovoltaic panel 3 uses the midday sunlight to generate electricity and power the main pump 401 for operation. The main pump 401 irrigates and stores water in the inner corrugated telescopic box 4. During the process of being filled with water, the inner corrugated telescopic box 4 simultaneously stretches upward to expand the internal volume. The inner corrugated telescopic box 4 temporarily stores irrigation water, and irrigation is not required at noon, reducing evaporation losses during noon irrigation, achieving the purpose of water saving, and avoiding the situation where the sunlight is strong at noon, the power generation is large, but the evaporation is also strong, and the evaporation loss is large due to relying on solar energy for irrigation, and the evaporation of water causes a large amount of waste.

[0027] In winter and other seasons when irrigation is not required, the upper electric screw 105 is driven by the motor to rotate, and the upper electric screw 105 drives the upper connecting frame 104 to move axially, and the upper connecting frame 104 drives the upper ends of the middle scissor bracket 102 to move away, and the height of the middle scissor bracket 102 is reduced. The middle scissor bracket 102 supports the upper box 201 to move down close to the lower box 2 to compress the space, and the height of the lower box 2 is reduced. The side photovoltaic panels 3 are folded in a bow shape on the top of the upper box 201, and the upper connecting brackets 303 on both sides of the side photovoltaic panels 3 are rotated to fit the back of the side photovoltaic panels 3. The two upper connecting brackets 303 are staggered inside and outside and fit on the back of the side photovoltaic panels 3, which reduces the overall volume and is convenient for moving indoors for storage, improving the use environment in winter and extending the service life; As the afternoon sun weakens, the power generation of the side photovoltaic panels 3 will also decrease, and the power of the main pump 401 will also decrease and gradually stop. When the main pump 401 gradually stops and for a period of time after the stop, the main pump 401 and the upper counterweight frame 403 generate downward pressure on the inner corrugated telescopic box 4 under gravity. The inner corrugated telescopic box 4 also has a certain water outlet pressure. The water outlet pressure of the inner corrugated telescopic box 4 increases, and the water pressure is compensated when the power of the main pump 401 decreases, and the water outlet speed of the lower water outlet pipe 202 is increased, so that the main pump 401 can also quickly discharge water when it stops. When the middle scissor bracket 102 supports the upper box body 201 to move upward, the connecting slide column 101 at the lower part of the middle scissor bracket 102 moves horizontally, and the middle scissor bracket 102 moves along the eight-shaped slide groove of the side limit support plate 103 through the connecting slide column 101, and the connecting slide column 101 pushes the side limit support plate 103 to move downward, and the side limit support plate 103 contacts the ground to fix the position, and the side limit support plate 103 supports the main frame 1 and the lower roller 106 upward, and the lower roller 106 is suspended in the air to avoid displacement, thereby ensuring the stability of the device during operation, and the solenoid valve of the rear water outlet pipe 204 is opened, and the rear water outlet pipe 204 supplies water to the water spray cleaning pipe 302, and the water spray cleaning pipe 302 discharges water to the side photovoltaic panel 3 to wash the surface dust, thereby ensuring the cleanliness of the surface of the side photovoltaic panel 3, and the personnel manually clean the side photovoltaic panel 3.
