Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic components, and in particular to a photovoltaic support component and an irrigation device with water collection and fixed-point irrigation functions. Background Art

[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect of semiconductor interfaces to directly convert light energy into electrical energy. The technical principle of photovoltaic power generation is mainly based on the photovoltaic effect. When photons irradiate metal or semiconductor materials, their energy can be completely absorbed by an electron in the material. If this energy is large enough, the electron can overcome the gravity inside the material to do work, escape from the surface of the material, and become a photoelectron. In photovoltaic cells, semiconductor materials such as silicon are usually used to form P-type and N-type semiconductors through a specific doping process. When they are combined together, a potential difference will be formed on the contact surface, that is, a solar cell. When sunlight irradiates the PN junction, holes move from the P-pole region to the N-pole region, and electrons move from the N-pole region to the P-pole region, thereby forming a current.

[0003] Photovoltaic power generation system is mainly composed of three parts: solar panels (modules), controllers and inverters. Solar cells are packaged and protected after being connected in series to form large-area solar cell modules. These modules, together with power controllers and other components, constitute a complete photovoltaic power generation device.

[0004] With the construction of the national Shagohuang new energy base, making full use of the rainwater collection / water collection effect of photovoltaic panels, promoting the ecological restoration of the base, and even developing the photovoltaic + planting industry has become one of the focus issues of common concern to all sectors of government, industry, academia, research and application. A series of water collection and water-saving utilization technologies and components have also been formed, but most of them are modular components added later, resulting in complex connections and instability between photovoltaic water collection components and brackets, low atmospheric precipitation / rainwater collection efficiency, high construction cost, and poor economic applicability, which in turn leads to the lack of possibility of large-scale promotion.

Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] The fixing component 2 also includes a first through hole 22 opened at the top of the fixed cross plate 21, and the first through hole 22 penetrates the fixed cross plate 21, a second through hole 26 opened at the top of the multi-section bent cross plate 25, and the second through hole 26 penetrates the multi-section bent cross plate 25, a fixing bolt 27 slidably connected to the inner cavity of the second through hole 26, and the bottom end of the fixing bolt 27 penetrates the first through hole 22 and the through hole 29, and a first nut 28 threadedly sleeved on the surface of the fixing bolt 27, and the first nut 28 is located below the C-shaped bracket beam 1.

[0037] The water flow guiding component 3 includes side baffles 31 fixedly installed on both sides of the C-type bracket beam 1. The C-shaped structure of the C-type bracket beam 1 is utilized, and the side baffles 31 are installed from both ends, so that the C-type bracket beam 1 forms a water storage container, and the rainwater and clean water collected on the photovoltaic panel 11 will be collected in the C-type bracket beam 1, which plays a role in collecting water. A blocking cap 33 is arranged above the through hole 29, a guide bolt 32 fixedly installed at the bottom of the blocking cap 33, and the bottom end of the guide bolt 32 extends to the bottom of the C-type bracket beam 1 through the through hole 29, and a second nut 34 is threadedly sleeved on the surface of the guide bolt 32, and the second nut 34 is located below the C-type bracket beam 1. The blocking cap 33 and the through hole 29 are adapted to each other, and the blocking cap 33 can block the through hole 29. By rotating the blocking cap 33, the through hole 29 and the blocking cap 33 can be staggered, and a gap can be left, and then the water source can pass through the through hole 29 along the guide bolt 32 for drainage operation.

[0038] The shielding component 4 includes a fixing seat 41 fixedly installed on the top of the multi-section bent horizontal plate 25 close to one end of the photovoltaic panel 11, a hinged seat 42 hinged at one end of the fixing seat 41, and a shielding mesh plate 43 arranged above the C-shaped bracket beam 1. The shielding mesh plate 43 is arranged to prevent dead branches, fallen leaves and insects from entering the C-shaped bracket beam 1. At the same time, it is semi-open, which is convenient for regular sludge flushing operations using a high-pressure water gun.

[0039] The shielding component 4 also includes a first limiting hole 44 opened on both sides of the top of the shielding mesh 43 near one end of the photovoltaic panel 11, and the first limiting hole 44 penetrates the shielding mesh 43, a second limiting hole 45 arranged on the top of the hinge seat 42, and the second limiting hole 45 penetrates the hinge seat 42, a limiting bolt 46 sleeved in the inner cavity of the second limiting hole 45, and the bottom end of the limiting bolt 46 penetrates the shielding mesh 43 through the first limiting hole 44, and a third nut 47 threadedly sleeved on the surface of the limiting bolt 46, and the third nut 47 is located below the shielding mesh 43.

[0040] During the use of the photovoltaic support component, first, when the C-shaped support beam 1 is used as a fixing part for the lower edge of the photovoltaic panel 11, it can support and fix the photovoltaic panel 11. At the same time, when rainwater and clean water fall onto the surface of the photovoltaic panel 11, they will be drained into the inner cavity of the C-shaped support beam 1 to collect water.

[0041] There are multiple groups of through openings 29 in the inner cavity of the C-type bracket beam 1. When the photovoltaic panel 11 is fixed by the fixed horizontal plate 21 and the multiple sections of bent horizontal plates 25, the fixing bolts 27 thereon pass through a group of through openings 29 and are fixed by screwing the first nut 28. At this time, the water collected in the C-type bracket beam 1 will flow down from the fixing bolts 27 through the through openings 29 and irrigate the plants directly below it.

[0042] At the same time, multiple groups of through openings 29 are opened in the C-shaped bracket beam 1, and multiple groups of through openings 29 are blocked by blocking caps 33. When more through openings 29 need to be opened to irrigate the plants below them, the second nut 34 on the corresponding through opening 29 can be rotated as needed to cancel the fixation between the blocking cap 33 on the guide bolt 32 and the through opening 29, and then the guide bolt 32 is rotated to make the blocking cap 33 and the corresponding through opening 29 misaligned, and then the second nut 34 is screwed again to fix the guide bolt 32 and the blocking cap 33, and then the water source in the C-shaped bracket beam 1 can be drained from the guide bolt 32 through the through opening 29 to perform on-site irrigation operations.

[0043] By rotating the fixed seat 41 and the hinged seat 42, the shielding mesh plate 43 can be rotatably installed above the multi-section bent horizontal plate 25. The shielding mesh plate 43 can block and protect the top of the C-type bracket beam 1 to prevent dead branches, fallen leaves and insects from entering the C-type bracket beam 1 and causing blockage. At the same time, the rotating connection of the shielding mesh plate 43 makes it convenient to flip up the shielding mesh plate 43, and facilitate cleaning operations such as regular flushing of silt and impurities with a high-pressure water gun. At the same time, the shielding mesh plate 43 is detachably fixed on the top of the C-type bracket beam 1 by limiting bolts 46 and third nuts 47, making actual installation or disassembly more convenient and the operation more convenient.

[0044] Example 2 Reference Figure 1-8 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the irrigation water storage component 5 includes a water storage tank 51 arranged on one side of the C-shaped bracket beam 1, a water inlet 52 connected to the top of one side of the water storage tank 51, a drain outlet 53 connected to one side of a group of side baffles 31, a connecting pipe 54 connected to the surface of the drain outlet 53, and one end of the connecting pipe 54 away from the drain outlet 53 is connected to the water inlet 52, a water outlet 55 connected to the bottom of one side of the water storage tank 51, and one end of the water outlet 55 is provided with a sealing plug, a filtering component 56 arranged in the inner cavity of the water storage tank 51, and a sealing component 57 arranged in the inner cavity of the water storage tank 51.

[0045] The filter assembly 56 includes a filter screen 561 installed on the top of both sides of the inner cavity of the water storage tank 51, and the filter screen 561 is set at an angle to facilitate the automatic rolling and falling of impurities filtered on the filter screen 561. A first connecting port 562 is opened on the top of one side of the water storage tank 51, and a second connecting port 563 is opened on the top of both ends of the water storage tank 51. Through the setting of the first connecting port 562 and the second connecting port 563, it is convenient to use a high-pressure water gun to regularly flush and clean impurities from the filter screen 561.

[0046] During the use of the photovoltaic support component, when too much rainwater and clean water collected on the photovoltaic panel 11 is collected in the C-shaped support beam 1, it can be discharged through the drain port 53 on the side baffle 31, and then transferred to the inner cavity of the water storage tank 51 through the connecting pipe 54, and then the water source entering the water storage tank 51 is filtered through the filter mesh plate 561, and then stored at the bottom of the inner cavity of the water storage tank 51, and used for irrigation in the subsequent dry season.

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

[0048] Example 3 Reference Figure 1-10 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the sealing component 57 includes an inverted cone water collecting plate 571 fixedly installed at both ends and both sides of the inner cavity of the water storage bin 51, and the inverted cone water collecting plate 571 is located below the filter screen plate 561, and a drainage pipe 572 connected to the bottom of the inverted cone water collecting plate 571 is convenient for collecting the filtered water source through the setting of the inverted cone water collecting plate 571, and then the filtered water falls from the drainage pipe 572 to the bottom of the inner cavity of the water storage bin 51 for storage, and a mounting horizontal plate 573 fixedly installed at both ends of the inner cavity of the water storage bin 51, and the mounting horizontal plate 573 is located at the inverted cone Between the water collecting plate 571 and the filter screen plate 561, there is a connecting rod 575 which is slidably connected to the top of the mounting horizontal plate 573, and the bottom end of the connecting rod 575 passes through the mounting horizontal plate 573 and the drainage circular pipe 572, and is fixedly mounted on the blocking chassis 574 at the bottom of the mounting horizontal plate 573, and the blocking chassis 574 is located below the drainage circular pipe 572, a spring 576 is sleeved on the surface of the connecting rod 575, one end of the spring 576 is interconnected with the top of the blocking chassis 574, and the other end of the spring 576 is interconnected with the bottom of the mounting horizontal plate 573, and a blocking cover 577 is arranged on the top of the connecting rod 575.

[0049] An annular sealing groove 578 is provided at the bottom of the drainage circular pipe 572, and a sealing ring 579 is fixedly installed at the top edge of the blocking chassis 574. The sealing ring 579 and the annular sealing groove 578 are adapted to each other, which can improve the sealing performance between the bottom of the drainage circular pipe 572 and the top of the blocking chassis 574.

[0050] During use of the photovoltaic support component, when the water source filtered from the filter plate 561 falls onto the top of the inverted cone water collecting plate 571 and gathers on the blocking chassis 574 at the bottom of the drainage circular pipe 572, as the water source increases, the blocking chassis 574 will be driven to move downward, and the connecting rod 575 will move downward. At the same time, the spring 576 will deform and stretch, and the water source will be discharged from the bottom of the drainage circular pipe 572 to the bottom of the inner cavity of the water storage tank 51. When there is no water source in the inner cavity of the drainage circular pipe 572, the rebound force of the spring 576 is used to make the sealing ring 579 on the blocking chassis 574 tightly attached to the annular sealing groove 578 on the drainage circular pipe 572, thereby ensuring the sealing of the bottom of the drainage circular pipe 572, and then the sealing of the water storage tank 51 can be improved, thereby reducing the evaporation of water during storage.

[0051] The remaining structure is the same as that of Example 2.

[0052] Example 4 Reference Fig.11 , which is the fourth embodiment of the present invention. A photovoltaic support component with water collection and fixed-point irrigation functions provided in this embodiment is basically the same as that in embodiment 1, except that: the shielding component 4' has a plane section 41' and a curved surface section 42', the plane section 41' and the curved surface section 42' are arranged in sequence in a direction away from the C-shaped support beam 1, and the plane section 41' is inclined downward in a direction away from the C-shaped support beam 1, and the inclination angle is preferably 20-40°, the head end of the curved surface section 42' is smoothly connected to the plane section 41', and The tail gradually extends upward along the inclined arc to form an arc-shaped slope. At the same time, the center of gravity of the shielding component 4' is located at its plane section 41', and the center of gravity is connected to the C-shaped bracket beam 1 via a hinge bracket 6, and the end of the shielding component 4' close to the C-shaped bracket beam 1 is connected to the C-shaped bracket beam 1 via a spring 7, and the spring 7 is kept in a stretched state, and the surface of the shielding component 4' is smooth and distributed with multiple filter holes (not shown in the figure), and the distribution density of the filter holes gradually increases in the direction away from the C-shaped bracket beam 1.

[0053] The shielding component 4' is used to filter the wet sand that flows with rainwater to the top of the C-shaped bracket beam 1, especially when there is a lot of sand on the photovoltaic panel area and the rainfall is heavy, the rapidly accumulated wet sand can be mainly concentrated on the arc section 42' of the shielding component 4', and when the weight of the wet sand accumulated on the arc section 42' exceeds the tension provided by the spring, the shielding component 4' is tilted outward to achieve automatic removal of the wet sand, and then automatically resets under the tension of the spring to continue filtering the sand and dust carried by the rainwater without any human intervention, thereby effectively improving the rainwater collection efficiency and its cleanliness.

[0054] 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.
