Description

Technical Field

[0001] The present invention relates to the technical field of power supply, and particularly to a hydrogen-water circulation distributed supply and demand intelligent energy system. Background Art

[0002] With the rapid development of the national economy, the energy demand in China has also increased significantly, and the energy supply-demand gap is getting larger and larger. At present, the per capita energy consumption level in China is still relatively low, and the growth pressure is very high. Therefore, we should cherish precious energy resources, improve energy utilization efficiency, and reduce energy consumption.

[0003] In the existing power supply system, hydrogen energy, wind energy, and solar energy are used to generate electricity, and grid-connected power supply is achieved by combining grid power generation. First, hydrogen energy power supply refers to using the combustion of hydrogen and oxygen to form a hydrogen-oxygen generator set. This type of unit is a rocket-type internal combustion engine structure equipped with a generator. It does not require a complex steam boiler system, so it is simple, easy to maintain, and can start quickly. It can be started or stopped immediately. When the grid load is low, it can also absorb excess electricity to electrolyze water to produce hydrogen and oxygen for power generation during peak hours. This regulatory function is beneficial to grid operation. Second, wind power generation refers to converting the kinetic energy of the wind into electrical energy. Finally, photovoltaic power generation uses solar cells to directly convert solar energy into electrical energy. The main components of a photovoltaic power generation device are solar cells, storage batteries, controllers, and inverters. Its characteristics are high reliability, long service life, no environmental pollution, and the ability to generate electricity independently and operate in parallel with the grid.

[0004] Among them, in the process of photovoltaic power generation, the photovoltaic panel is a key component. However, in actual use, the conversion efficiency of the photovoltaic panel is limited.

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0040] Embodiment 1

[0041] Please refer to Figure 1-8, the present invention provides a technical solution: a hydrogen-water cycle distributed supply and demand intelligent energy system, including a power supply module. The power supply module includes a power grid, a wind power generation device, a photovoltaic power generation device, and a hydrogen fuel cell. The hydrogen fuel cell is connected to a constant temperature cold and hot water circulation system. The power grid, the wind power generation device, the photovoltaic power generation device, and the hydrogen fuel cell are connected to the grid for power generation. Among them, during the operation of the hydrogen fuel cell, a proton exchange membrane fuel cell uses hydrogen and air (or oxygen) as reaction raw materials, generates water during the reaction process, and discharges a large amount of heat, which accounts for about 40% - 50% of the total energy. This heat will affect the normal operation of the fuel cell. The high temperature state will greatly limit the output power of the fuel cell. In winter, when the hydrogen fuel cell starts below zero degrees Celsius, there will be a phenomenon of slow start or inability to start. Most existing fuel cells perform special treatment on the proton exchange membrane to achieve the effect of cold start, but this cold start method has two disadvantages: the first is that this start will affect the life of the proton exchange membrane, and the second is that the requirements for the proton exchange membrane are relatively high, resulting in a large increase in cost. Therefore, a constant temperature cold and hot water circulation system is used for heat dissipation during the operation of the hydrogen fuel cell.

[0042] In view of this, conduct in-depth research on the water cycle, add external assistance to achieve better cold start, and obtain a water cycle system for a hydrogen fuel cell;

[0044] In the cleaning work of the photovoltaic panel 24, it is divided into four steps. The first step is to wipe the dust on the surface of the photovoltaic panel 24 with a wet sponge. The second step is to flush the surface of the photovoltaic panel 24 by the flushing mechanism 4. The third step is to wipe and clean the water stains on the surface of the photovoltaic panel 24 with a dry sponge. The fourth step is to dry the photovoltaic panel 24 by the drying mechanism 5. Among them, the position where the wet cleaning mechanism is located is the first working position, the position where the flushing mechanism 4 is located is the second working position, the position where the dry cleaning mechanism is located is the third working position, and the position where the drying mechanism 5 is located is the fourth working position;

The photovoltaic panel 24 is movably installed in the lifting frame 218 through a translation mechanism 23. Both sides of the lifting frame 218 are rotatably connected to a third connecting rod 216 through a second rotating shaft 2142. The free end of the third connecting rod 216 is rotatably connected to a fourth connecting rod 217. The free end of the fourth connecting rod 217 is rotatably connected to a lifting frame 218a.

At the same time, the second connecting rod 213 drives the first rotating shaft 2141 to rotate, and the first rotating shaft 2141 drives the first gear 2151 to rotate. According to the meshing transmission principle of the gear teeth, the first gear 2151 drives the second gear 2152 to rotate. The second gear 2152 drives the second rotating shaft 2142 to rotate. The second rotating shaft 2142 drives the third connecting rod 216 to expand upward. The third connecting rod 216 drives the fourth connecting rod 217 to expand upward, and then drives the lifting frame 218a to rise, and then the photovoltaic panel 24 on the lifting frame 218 extends out of the outside of the box body 1 to absorb solar energy for photovoltaic power generation. Moreover, the photovoltaic panel 24 can also be driven to rotate by the second motor 231 to adjust the angle of the photovoltaic panel 24 according to the light angle, improving the absorption effect of the photovoltaic panel 24 on solar energy. On the contrary, when the output end of the electric hydraulic cylinder 211 retracts, it drives the lifting frame 218 to drive the photovoltaic panel 24 to descend and be stored in the box body 1.

[0051] Assuming that in the initial state, the second through groove 2181 faces the wet cleaning mechanism of the first station and the dry cleaning mechanism of the third station, firstly, the third gear 2331 is driven to rotate by the third motor 2351, and the third gear 2331 drives the first rack 2321 to drive the slider 234 to move close to the first station, so that the photovoltaic panel 24 enters under the wet sponge, and then, the photovoltaic panel 24 is driven clockwise by the rotating mechanism 22 to rotate to the second station, the third station and the fourth station in turn, so as to complete the cleaning of the half side surface of the photovoltaic panel 24;

[0052] Next, the other half of the photovoltaic panel 24 is cleaned by first rotating the rotating mechanism 22 180 degrees clockwise to align the uncleaned side of the photovoltaic panel 24 with the first station.

[0057] Working principle: When in use, first, the output end of the electric hydraulic cylinder 211 extends to drive the first connecting rod 212 to expand upward, and under the linkage action of the second connecting rod 213, the lifting frame 218b is driven to rise. At the same time, the second connecting rod 213 drives the first rotating shaft 2141 to rotate, and the first rotating shaft 2141 drives the first gear 2151 to rotate.

Conversely, when the output end of the electric hydraulic cylinder 211 retracts, the lifting frame 218 is driven to drive the photovoltaic panel 24 to descend and be stored in the box body 1. The box body 1 allows the photovoltaic power generation device to exist as a whole, and when in use, it can be adapted to different geographical locations for use;

[0058] Secondly, the flushing mechanism 4 can also be used for cooling the photovoltaic panel 24. When the surface temperature of the photovoltaic panel 24 is too high, the lifting frame 218 is lowered by adjusting the lifting mechanism 21, and then the lifting frame 218 is rotated by driving the rotation mechanism 22, so that the second through groove 2181 faces the second station. The photovoltaic panel 24 is driven by the translation mechanism 23 to move below the spray plate 43 to cool the surface of one side of the photovoltaic panel 24 by water cooling. After water cooling for a period of time, the lifting frame 218 is driven by the rotation mechanism 22 to rotate clockwise by 180 degrees again, and the surface of one side of the photovoltaic panel 24 is cooled by air cooling by the fan 54. After air cooling for a period of time, the photovoltaic panel 24 is driven by the translation mechanism 23 to move below the spray plate 43 again, and the above-mentioned water cooling and air cooling operations are repeated to complete the cooling work of the photovoltaic panel 24. After the photovoltaic panel 24 is cooled, it is driven by the lifting mechanism 21 to extend out of the box body 1 again to continue absorbing solar energy, improving the problem of reduced power conversion efficiency caused by the too high surface temperature of the photovoltaic panel 24;

[0059] Among them, when there is too much dust on the surface of the photovoltaic panel 24, assuming that in the initial state, the second through groove 2181 faces the wet cleaning mechanism at the first station and the dry cleaning mechanism at the third station, then first, the third gear 2331 is rotated by driving the third motor 2351, and the third gear 2331 drives the first rack 2321 to drive the slider 234 to move close to the first station, so that the photovoltaic panel 24 enters below the wet sponge. Secondly, the photovoltaic panel 24 is driven by the rotation mechanism 22 to rotate clockwise to the second station, the third station and the fourth station in sequence to complete the cleaning of half of the surface of the photovoltaic panel 24;

[0060] Next, the other half of the photovoltaic panel 24 is cleaned. First, the rotation mechanism 22 is rotated clockwise by 180 degrees to align the uncleaned side of the photovoltaic panel 24 with the first station. Then, the fourth gear 2332 is rotated by driving the fourth motor 2352, and the fourth gear 2332 drives the second rack 2322 to drive the slider 234 to move close to the first station, so that the photovoltaic panel 24 enters below the wet sponge. Then, the photovoltaic panel 24 is driven by the rotation mechanism 22 to rotate clockwise to the second station, the third station and the fourth station in sequence to complete the cleaning of the other half of the surface of the photovoltaic panel 24. Thus, the cleaning action of the surface of the photovoltaic panel 24 is completed, reducing and avoiding too much dust covering the surface of the photovoltaic panel 24, improving the power generation efficiency of the photovoltaic panel 24, and avoiding manual labor, saving time and effort, and reducing labor intensity.
