[0002] Industrial parks have demands for refrigeration, heating, and water vapor, and the functional planning of newly built industrial parks has gradually become an issue of concern to local governments.

[0003] As disclosed in announcement number CN218829753U, a new photovoltaic power supply device is disclosed, wherein mounting blocks are symmetrically arranged on the lower surface of the photovoltaic power supply panel, a connecting rod is installed on the lower surface of the mounting block, an adjustment assembly is arranged at the lower end of the connecting rod, the adjustment assembly includes an adjustment rod installed on the lower surface of the connecting rod, and a support rod is arranged on the outside of the adjustment rod; a mounting frame is installed on the outside of the photovoltaic power supply panel by screws, a cleaning assembly is arranged below the mounting frame and above the photovoltaic power supply panel, and the cleaning assembly includes a second movable plate arranged below the mounting frame. The first movable plate is moved downward by using the first electric telescopic rod, and the second movable plate is moved on the surface of the photovoltaic power supply panel by using the second electric telescopic rod. During the movement, the cleaning pad can clean the surface of the photovoltaic power supply panel, thereby preventing the photovoltaic power supply panel from being exposed to dust and affecting its use;

[0004] For example, announcement number CN203188646U discloses a device for reinforcing and installing photovoltaic panels in steel structure workshops, including an existing steel structure workshop, an installation device and a reinforcement device. The workshop includes steel beams, frame columns and a roof, the roof includes an insulation layer and a corrugated plate, the reinforcement device includes a pile foundation, a frame, steel cables, struts, a tension adjustment device and an anchor, and the installation device includes a keel, a force transmission support and a shaped plate. The utility model performs multi-span synchronous tensioning reinforcement on an existing steel structure workshop to improve the bearing capacity of the light steel roof, which is used to place photovoltaic power generation equipment, thereby building a photovoltaic power station on the roof of the light steel workshop, making full use of the vast space above the light steel workshop;

[0005] However, the existing photovoltaic power supply system in industrial parks still has the following shortcomings:

[0006] 1. In the existing photovoltaic power supply system in industrial parks, photovoltaic panels are mostly fixed on the top of the factory building by bolts and external installation tools. The installation operation is inconvenient and it is not convenient to disassemble and assemble the photovoltaic panels;

[0007] 2. In the existing photovoltaic power supply system in industrial parks, the installation angle of photovoltaic panels on the top of the factory building is mostly fixed and inconvenient, which makes it inconvenient to adjust the angle of photovoltaic panels according to the change of light direction, and the actual effect of receiving light needs to be improved;

[0008] 3. The existing photovoltaic power supply system in industrial parks requires a large number of battery packs to achieve energy storage. At the same time, the amount of electrical storage is closely related to the number of batteries. At present, most industrial parks adopt a phased construction method.

[0041] See also Figure 1-Figure 8 , the present invention provides the following technical solutions:

[0042] Embodiment 1: In order to solve the problem in the prior art that most photovoltaic panels 10 are fixed on the roof of the factory building by bolts and with the help of external installation tools, the installation operation is inconvenient, and it is inconvenient to disassemble and assemble the photovoltaic panels 10, the present embodiment adopts the following technical scheme: an industrial park photovoltaic power supply system, provided with a mounting bracket 7, a mounting groove 8, an auxiliary plate 9, a photovoltaic panel 10, a mounting support rod 11, a protrusion 12 and a mounting mechanism 13, a plurality of groups of photovoltaic panels 10 are arranged on the upper end of the mounting bracket 7, and mounting mechanisms 13 are arranged on the left and right ends of the mounting bracket 7, the mounting mechanism 13 is used to install and position the photovoltaic panel 10 and the mounting bracket 7, and the mounting mechanism 13 drives the photovoltaic panel 10 to form a disassembly structure at the upper end of the mounting bracket 7, and the mounting mechanism 13 comprises a movable plate 14 hingedly connected to the front and rear ends of the auxiliary plate 9, a first connecting groove 15 opened in the middle of the movable plate 14, a second connecting groove 16 opened at the end of the movable plate 14 away from the auxiliary plate 9, an auxiliary rod 17 for connection and a fixing cap 18 with a locking and limiting function, the movable plate 14 respectively forms a flip structure at the front and rear ends of the auxiliary plate 9, and the movable plate 14 is fitted on the upper end of the mounting support rod 11, a convex block 12 is engaged in the first connecting groove 15, the auxiliary rod 17 is engaged in the second connecting groove 16, the auxiliary rod 17 and the fixing cap 18 are connected by a threaded manner, and the fixing cap 18 is fitted on the upper end of the movable plate 14, the movable plate 14 is fitted on the upper end of the mounting bracket 7, and the auxiliary rod 17 is fixedly connected to the mounting bracket 7;

[0043] like Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, the photovoltaic panel 10 is arranged on the upper end of the mounting bracket 7, and the photovoltaic panel 10 drives the mounting support rod 11 to be placed in the mounting groove 8, and then the movable plate 14 is flipped, and the movable plate 14 is rotated on the auxiliary plate 9, so that the movable plate 14 is clamped and fitted on the upper end of the mounting support rod 11, and the first connecting groove 15 is clamped with a protrusion 12, and the auxiliary rod 17 is clamped in the second connecting groove 16, and then the fixing cap 18 threadedly connected to the outer surface of the auxiliary rod 17 is rotated, so that the fixing cap 18 is fitted and set on the upper end of the movable plate 14, so as to facilitate the positioning between the mounting support rod 11 and the mounting bracket 7, and thus the photovoltaic panel 10 can be installed and positioned very conveniently;

[0044] Embodiment 2: In the existing photovoltaic power supply system in industrial parks, the installation angle of the photovoltaic panel 10 on the top of the factory building is mostly fixed and inconvenient, and it is not convenient to adjust the angle of the photovoltaic panel 10 according to the change of the direction of light, and the actual effect of receiving light needs to be improved. Therefore, by setting a fixed mounting plate 5, a support plate 6, a mounting bracket 7, an electric telescopic rod 19, a connecting mechanism 20 and a light sensor 24, the mounting bracket 7 and the photovoltaic panel 10 are respectively arranged at the upper ends of the steam demand factory building 1, the heat demand factory building 2, the cold demand factory building 3 and the electric energy storage room 4, and the left and right sides of the upper end of the mounting bracket 7 are installed with light sensors 24, and the connecting mechanism 20 is connected to the upper end of the photovoltaic panel 10. The connecting mechanism 20 is arranged at the right end of the mounting bracket 7, and the connecting mechanism 20 drives the upper end of the fixed mounting plate 5 through the mounting bracket 7 to form a flip structure. The upper ends of the steam demand plant 1, the heat demand plant 2, the cold demand plant 3 and the electric energy storage room 4 are fixedly installed with an electric telescopic rod 19. The connecting mechanism 20 includes a connecting block 21 fixedly connected to the output end of the electric telescopic rod 19, a movable sleeve 22 hingedly connected to the upper end of the connecting block 21, and a connecting column 23 plugged into the middle of the movable sleeve 22. The connecting column 23 is respectively fixedly connected to the front and rear sides of the right end of the mounting bracket 7, and a sliding structure is formed between the connecting column 23 and the movable sleeve 22. Figure 2 , Figure 4 and Figure 8 As shown, the light intensity is sensed by the light sensor 24. When the light angle and intensity change during the day, the light sensor 24 transmits the information of the light angle change to the central processing unit, and the central processing unit controls the start of the electric telescopic rod 19. The electric telescopic rod 19 pushes the connecting block 21 to move upward or downward. At this time, the connecting block 21 rotates with the movable sleeve 22, thereby driving the movable sleeve 22 to slide on the outer surface of the connecting column 23. At this time, the connecting column 23 drives the mounting bracket 7 and the support plate 6 to rotate, thereby driving the photovoltaic panel 10 to flip over at the upper end of the factory building, and adjusting the angle of the photovoltaic panel 10 so that the photovoltaic panel 10 can better receive light and make better use of sunlight.

[0045] Embodiment 3: The existing photovoltaic power supply system in the industrial park has poor energy storage effect, low utilization rate of steam inside the factory, and low utilization rate of photovoltaic power. Therefore, by setting steam demand factory 1, heat demand factory 2, cold demand factory 3, electric energy storage room 4, inverter, condenser and evaporator, etc. Figure 1As shown, steam demand plant 1, heat demand plant 2, cold demand plant 3 and electric energy storage room 4 are arranged from left to right. There is a matching relationship between steam demand plant 1, heat demand plant 2 and cold demand plant 3. The electric energy storage room 4 is equipped with a battery pack inside by electrically driving the compressed steam refrigeration cycle. In actual use, the layout of the park fully considers the needs of each processing unit for heat, cold and steam. The plant is laid out according to the "steam-heat-cold" plan. Photovoltaic cells are arranged on the roofs of all buildings and available south-facing surfaces in the park. An electric energy storage room 4 is arranged in the park for centralized storage and release of photovoltaic cells and municipal power supply. The electric energy generated by the photovoltaic cells can enter the power grid through the inverter for surplus power access to the grid, and can also enter the electric energy storage room 4 for energy storage. The unrectified AC power generated by the photovoltaic cells can also be directly used for heating hot water and steam. The non-steady-state heating at these locations can also meet the heating needs, thereby improving the utilization rate of photovoltaic power.

[0046] The municipal valley electricity can also enter the electric energy storage room 4 for valley electricity storage, or directly enter the system to drive refrigeration cycle, electric heating and steam heating. In addition, there is a matching relationship between the steam demand plant 1, the heat demand plant 2 and the cold demand plant 3. By electrically driving the compressed steam refrigeration cycle, cold energy is obtained on the evaporator side of the cycle, and heat energy is obtained on the condenser side of the cycle, and the corresponding plants are supplied respectively. The high-pressure hot water generated by heating in the heat plant can be directly decompressed and gasified into water vapor and enter the steam plant for use. The Rankine cycle principle can also be used to drive the turbine generator module to generate electric energy to feed back to the power grid or the electric energy storage module. The generated steam exhaust steam enters the steam plant for subsequent use. In this way, the three systems and the power grid can realize energy intercommunication, and there is also a cascade utilization of energy between the three systems, which can greatly improve the overall energy efficiency of the system, thereby achieving the purpose of energy saving and consumption reduction and carbon emission reduction.

[0047] At the same time, the photovoltaic panels 10 arranged above the factory buildings in the park can be used for self-use in the factory area and for the grid connection of surplus photovoltaic power. They can store low-cost electric heat and green electricity through electric-heat conversion. After the unstable photovoltaic and wind power are converted into thermal energy storage, they can be stably output on demand, making steam decarbonization possible from impossible; they are stored in the form of high-temperature and high-pressure water in the heat accumulator, and when production is needed, the high-temperature and high-pressure water is released from the heat accumulator and converted into steam for production use by the enterprise; the steam is stored in the form of water, and its volume is reduced to 1 / 50-1 / 60 of the original volume. Valley electricity consumption: valley electricity of the power grid is converted into thermal energy storage to produce steam, so as to realize peak shaving and valley filling of the power grid, and the low electricity price advantage of valley electricity is used to turn the electric energy substitution in the steam field from economically unfeasible to feasible, and the electricity fee income is converted into steam income. Electric-heat cooperative control: the electric-steam heat storage system can instantly control the release of steam, and the thermal energy system with large inertia and large delay is connected with the power grid system. The cooperative control between the heat network and the power grid is possible from impossible, and adaptive real-time flexible interaction is realized, and a new demand response model is established.
