Description

Technical Field

[0001] The present invention relates to the technical field of automatic feeding of fishery-photovoltaic complementarity, and in particular to a photovoltaic device capable of automatic feeding based on fishery-photovoltaic complementarity and a method of using the same. Background Art

[0002] With the development of the global economy, the demand for energy continues to increase. Traditional fossil energy (such as coal, oil and natural gas) faces many problems such as limited reserves, price fluctuations and environmental pollution. For example, burning coal will release a large amount of carbon dioxide, sulfur dioxide and nitrogen oxides, leading to environmental problems such as global warming and acid rain. Moreover, the supply of traditional energy is greatly affected by factors such as geopolitics, and there are risks in the stability of supply. Against this background, the development and utilization of renewable energy (such as solar energy, wind energy, hydropower, etc.) has become a key focus of the global energy field. As a clean energy, solar energy has the advantages of wide distribution and almost unlimited resources. Converting solar energy into electrical energy through photovoltaic power generation technology can alleviate the energy crisis to a certain extent and reduce the negative impact on the environment.

[0003] The concept of "fish-photovoltaic complementarity" was born, and the water area was used for both fish farming and photovoltaic power generation to achieve multiple utilization of space resources. However, in the environment of fish-photovoltaic complementarity, the installation of photovoltaic panels takes up a lot of space, especially in feeding. Due to the obstruction of photovoltaic panels, fish can only be fed at the edge of the fish pond, making it impossible for fish farther away to get fish food, or to feed them by boat. During the feeding process by boat, it is easy to throw feed onto the surface of the photovoltaic panels, which will contaminate the photovoltaic panels and affect the power generation efficiency of the photovoltaic panels, which is not conducive to feeding and power generation. The fish in the water need to be fed every day, and the method of feeding by boat will increase the fatigue of the feeding personnel. Summary of the invention

DETAILED DESCRIPTION

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0035] Example 1

[0036] Reference Figure 1-7 , which is the first embodiment of the present invention, provides a photovoltaic device based on fish-photovoltaic complementarity and capable of automatic feeding, comprising: an I-shaped mounting plate 1 and a photovoltaic panel 2, a plurality of photovoltaic panels 2 are arranged at the inclined surface of the I-shaped mounting plate 1, and the photovoltaic panel 2 and the I-shaped mounting plate 1 are connected via an L-shaped mounting plate, characterized in that: a reinforcing plate is arranged at the inclined surface of the lower end of the photovoltaic panel 2, and the inclined surfaces of the lower ends of a pair of reinforcing plates are fixedly connected to the same L-shaped loading rod 3, a pair of mutually symmetrical feeding devices 4 are installed on the L-shaped loading rod 3, and the feeding device 4 comprises: a feed placing box 5, and a feeding pipe 6 is penetrated and connected at the lower surface of the feed placing box 5;

[0037] A connecting ring 7 is installed on the arc surface of the outer part of the feeding tube 6, and a U-shaped reinforcement plate 8 is fixedly provided on the arc surface of the connecting ring 7, and the U-shaped reinforcement plate 8 is connected to a spreading disc 9 at the vertical surface away from the connecting ring 7, and a rectangular placement plate 10 is fixedly provided on the arc surface of the outer part of the feeding tube 6, and a driving motor 11 is provided on the upper surface of the rectangular placement plate 10, and a power-on relay 12 is also installed on the upper surface of the disc 9, and an arc-shaped docking wire 13 is also provided at the connection port of the power-on relay 12, and the end of the arc-shaped docking wire 13 away from the power-on relay 12 is connected to the driving motor 11. A time relay refers to a relay whose output circuit needs to wait for a set time to reach before the contact action is generated after the coil is energized. The timing starts when the coil is energized, and the coil will reset when the power is off. When the set time is reached, the normally open contact is closed and the normally closed contact is disconnected. The power-on relay 12 controls the on and off of the coil, and uses electromagnetic force to realize the opening and closing of the contacts, thereby achieving the purpose of controlling the on and off of the circuit 24. This working principle allows the relay to use a smaller current to control a larger current or a higher voltage, and plays the role of automatic adjustment, safety protection, and circuit conversion in the circuit. A small inverter is installed on the vertical surface of the feed placement box 5. In the solar photovoltaic power generation system, the direct current generated by the solar panel needs to be converted into alternating current through an inverter before it can be connected to the power grid or used in homes, businesses, and other places.

[0038] A circular rotating sleeve 14 is arranged below the feeding tube 6 , and a plurality of L-shaped limiting rods 15 with the same spacing are arranged on the outer wall of the feeding tube 6 , and an arc-shaped limiting groove 16 is also provided at the intersection of the L-shaped limiting rod 15 and the circular rotating sleeve 14 .

[0039] The cross section of the lower end of the discharge pipe 6 is rotatably connected to several cylindrical tubes 17, and the rod body of the cylindrical tubes 17 is provided with an arc-shaped rotating plate 18, and there is a sliding relationship between the arc-shaped rotating plate 18 and the discharge pipe 6. The inner ring of the annular rotating sleeve 14 is fixedly connected to several arc-shaped positioning plates 19, and the lower surfaces of the arc-shaped positioning plates 19 and the arc-shaped rotating plates 18 are provided with rotating round rods 20. The arc surfaces of a pair of rotating round rods 20 are penetrated by the same arc-shaped pull rod 21, and the arc surface of the outer side of the annular rotating sleeve 14 is provided with several arc-shaped guide blocks 22.

[0040] An L-shaped limit plate 23 is provided on the lower surface of the rectangular placement plate 10, and a round rod 24 is penetrated on the upper surface of the L-shaped limit plate 23. The round rod 24 and the rod body at the output end of the driving motor 11 are both provided with a bevel gear 25 penetrated therethrough, and the pair of bevel gears 25 are meshed with each other. The lower surface of the round rod 24 is fixedly connected to the mounting rod, and a gear plate 26 is penetrated therethrough on the rod body of the mounting rod.

[0041] The gear plate 26 and the arc-shaped guide block 22 are in a mutually meshing relationship, and a rectangular moving groove 27 is provided at the intersection of the arc-shaped guide block 22 and the circular rotating sleeve 14, a guide rod 28 is provided between the vertical surfaces opposite to the rectangular moving groove 27, and a memory spring 29 is also provided at the vertical surface of the rectangular moving groove 27, a rotating fan blade 30 is provided at the bottom surface inside the disk 9, an arc-shaped groove 31 is provided through the arc surface outside the disk 9, and a plurality of cylindrical gear rods 32 with the same spacing are provided at the bottom surface of the arc-shaped groove 31.

[0042] When in use, because the upper surface of the disc 9 is also equipped with a power relay 12, the end of the arc-shaped docking line 13 away from the power relay 12 is connected to the drive motor 11, and a small inverter is also installed on the vertical surface of the feed placement box 5, so when the time changes from evening to morning, the photovoltaic panel 2 starts to work, because the small inverter is also provided with a pair of connecting wires, one of which is first connected to the photovoltaic panel 2, and the other is connected to the power relay 12, so when the photovoltaic panel 2 starts to generate electricity, a part of the electricity will first enter the small inverter through the connection, and then through the conversion of the small inverter, the power of the electricity will be converted into a range that can be used by the power relay 12. With the power supply to the power relay 12, the power relay 12 will start to work, thereby starting the timing process, and when the accumulated time of the power relay 12 reaches the preset value, the power relay 12 will start the drive motor 11;

[0043] As the drive motor 11 is started, the output end of the drive motor 11 will rotate, because the round rod 24 and the rod body of the output end of the drive motor 11 are both provided with a bevel gear 25 penetrated therethrough, and a pair of the bevel gears 25 are meshed with each other, and the lower surface of the round rod 24 is fixedly connected to the mounting rod, and the rod body of the mounting rod is provided with a gear plate 26 penetrated therethrough, so when the drive motor 11 is started, the gear plate 26 will drive the annular rotating sleeve 14 to rotate through several arc-shaped guide blocks 22, and as the annular rotating sleeve 14 rotates, the arc-shaped pull rod 21 will pull the arc-shaped rotating plate 18, thereby changing the angle of the arc-shaped rotating plate 18, and when the annular rotating sleeve 14 completes its rotation, the feed can fall into the inside of the disc 9.

[0044] Example 2

[0045] Reference Figure 2 and 3, which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the gear plate 26 and the arc-shaped guide block 22 are in a meshing relationship with each other, and a rectangular moving groove 27 is provided at the intersection of the arc-shaped guide block 22 and the annular rotating sleeve 14, a guide rod 28 is provided between the vertical surfaces opposite to each other of the rectangular moving groove 27, and a memory spring 29 is also provided at the vertical surface of the rectangular moving groove 27, a rotating fan blade 30 is provided at the bottom surface of the inner part of the disk 9, an arc-shaped groove 31 is provided through the arc surface of the outer part of the disk 9, and a plurality of cylindrical levers 32 with the same spacing are provided at the bottom surface of the arc-shaped groove 31.

[0046] When in use, first follow the operating steps in Example 1. As the circular rotating sleeve 14 rotates, the arc pull rod 21 will pull the arc rotating plate 18, thereby changing the angle of the arc rotating plate 18. When the circular rotating sleeve 14 completes its rotation, the drive motor 11 will continue to rotate. When the drive motor 11 is just started, the mounting rod fixedly connected to the gear plate 26 will also rotate. Because the rotating blades 30 are connected to the mounting, the rotating blades 30 will also rotate. As the rotating blades 30 rotate, the rotating blades 30 will collect the feed that falls into the disc 9, and during the rotation process, through the influence of the rotational force and the centrifugal force, the feed is spread onto the water surface through the arc groove 31, thereby realizing the automatic feeding process.

[0047] The remaining structures are the same as those of Example 1.

[0048] Example 3

[0049] Reference Figure 3 , 8 9 is the second embodiment of the present invention, which is different from the first and second embodiments in that: a rectangular filter box 33 is penetrated and connected at the vertical surface of the feed placement box 5, a mesh screen 34 is arranged on the bottom surface inside the rectangular filter box 33, a water-absorbing sponge 35 is arranged on the side of the mesh screen 34 close to the feed placement box 5, a filter net 36 is arranged on the side of the water-absorbing sponge 35 close to the feed placement box 5, a rectangular water discharge box is penetrated and connected at the bottom surface outside the rectangular filter box 33, and a circular baffle 37 is arranged just below the rectangular water discharge box, and rectangular plates 38 are connected to both sides of the circular baffle 37, and a pair of lifting guide rods 39 are penetrated on the upper surfaces of the rectangular plates 38.

[0050] During use, when personnel find that there is no feed, they first let the feed be poured into the feed placement box 5 manually. Because a suction fan is installed through the vertical surface of the rectangular filter box 33, when the loading is completed, the driving motor on the suction fan is started. As the driving motor rotates, the air will first enter the interior of the rectangular filter box 33. At this time, the air will first contact the mesh screen 34. The mesh screen 34 can well isolate small insects and larger dust in the air. Then, the air containing water vapor will pass through the water-absorbing sponge 35. When passing through the water-absorbing sponge 35, most of the water vapor in the air will be absorbed by the water-absorbing sponge 35, and then pass through the filter net to completely isolate the insects that cannot be filtered by the mesh screen 34. After absorbing water for a long time, the water-absorbing sponge 35 gradually condenses at the bottom of the water-absorbing sponge 35 under the influence of gravity, thereby forming water droplets, which will eventually drip into the interior of the rectangular water storage box.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.

A photovoltaic device for automatically feeding fish based on photovoltaic complementarity as claimed in any one of claims 1 to 8, comprising the following processing steps: because a power relay (12) is also installed on the upper surface of the disc (9), the end of the arc-shaped butt-joint wire (13) away from the power relay (12) is connected to the drive motor (11), and a small inverter is also installed on the vertical surface of the feed placement box (5), so when the time changes from evening to morning, the photovoltaic panel (2) starts to work, because a pair of connecting wires are also provided on the small inverter, one of which is connected to the end connected to the photovoltaic panel (2) first. The other connecting line is connected to the power-on relay (12), so when the photovoltaic panel (2) starts to generate electricity, a part of the electricity will enter the small inverter through the connection first, and then the small inverter will convert the power of the electricity into a range that can be used by the power-on relay (12). As the power is supplied to the power-on relay (12), the power-on relay (12) will start to work, thereby starting the timing process, and when the accumulated time of the power-on relay (12) reaches a preset value, the power-on relay (12) will start the drive motor (11); As the drive motor (11) is started, the output end of the drive motor (11) will rotate, because the round rod (24) and the rod body of the output end of the drive motor (11) are both provided with a bevel gear (25) penetrated therethrough, and a pair of the bevel gears (25) are meshed with each other, and the lower surface of the round rod (24) is fixedly connected to the mounting rod, and the rod body of the mounting rod is provided with a gear plate (26) penetrated therethrough, so when the drive motor (11) is started, the gear plate (26) will drive the annular rotating sleeve (14) to rotate through a plurality of arc-shaped guide blocks (22), and as the annular rotating sleeve (14) rotates, the arc-shaped pull rod (21) will pull the arc-shaped rotating plate ( 18), thereby changing the angle of the arc-shaped rotating plate (18). When the annular rotating sleeve (14) completes its rotation, the driving motor (11) will continue to rotate. When the driving motor (11) is just started, the mounting rod fixedly connected to the gear plate (26) will also rotate. Since the rotating blades (30) are connected to the mounting rod, the rotating blades (30) will also rotate. As the rotating blades (30) rotate, the rotating blades (30) will collect the feed that falls into the disc (9), and in the process of rotation, the feed is spread onto the water surface through the arc-shaped groove (31) by the influence of the rotation force and the centrifugal force, thereby realizing the automatic feeding process.
