Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of prefabricated cabins, in particular to a new energy photovoltaic power generation prefabricated cabin. BACKGROUND

[0002] The new energy photovoltaic power generation prefabricated cabin belongs to the supporting equipment of a photovoltaic power station. The core power equipment such as inverters, transformers, power distribution cabinets and energy storage devices are integrated and assembled in a factory, and then installed through on-site rapid deployment, effectively replacing the construction mode of traditional civil power distribution rooms. With the modular design, the prefabricated cabin not only significantly shortens the construction period of the photovoltaic power station and reduces the comprehensive construction cost, but also improves the quality reliability and environmental adaptability of equipment operation, providing important support for the intelligent operation and maintenance of the photovoltaic system, and has become a key supporting facility for distributed and centralized photovoltaic power stations.

[0003] A photovoltaic combined prefabricated cabin is disclosed in Chinese patent with authorization announcement No. CN116411733B, which is applied in the technical field of prefabricated cabins, and includes a crossbar. The bottom of the crossbar is bolted with a support leg, and the top of the crossbar is provided with a bottom plate. By setting the crossbar and the support leg, the structure can be conveniently installed and placed, and is separated from the ground by a certain distance to avoid water accumulation caused by low-lying ground. The bottom plate is installed with the mounting plate, which can facilitate the installation of the bottom plate and the structure connected thereto on the top of the crossbar. The left side plate, top plate, right side plate and bottom plate are cooperated to form the four sides of the prefabricated cabin, and the front and rear sides of the prefabricated cabin are closed by the installation of the door plate.

The photovoltaic panel cooperates with the junction box, and the controller, inverter and battery connected externally can generate photovoltaic power to supply part of the electricity of the internal equipment, making the structure more energy-saving and environmentally friendly.

[0032] Example 1:

[0033] This invention provides a prefabricated photovoltaic power generation module for new energy sources, such as... Figures 1-6 As shown, it includes: a cabin 1, a horizontally arranged bulkhead 2 inside the cabin 1, the rear end of the bulkhead 2 being fixedly connected to the rear inner wall of the cabin 1, a left bulkhead 3 vertically arranged on the upper left side of the bulkhead 2, the lower end of the left bulkhead 3 being fixedly connected to the upper surface of the bulkhead 2, a right bulkhead 4 vertically arranged on the upper right side of the bulkhead 2, the lower end of the right bulkhead 4 being fixedly connected to the upper surface of the bulkhead 2, and the rear sides of both the left bulkhead 3 and the right bulkhead 4 being connected to the rear inner wall of the cabin 1, an installation cavity 5 provided on the upper side of the bulkhead 2, a first flow cavity 6 provided on the lower side of the bulkhead 2, and a side of the left bulkhead 3 away from the right bulkhead 4 being provided with A second flow chamber 7 is provided, and a third flow chamber 8 is provided on the side of the right partition 4 away from the left partition 3. The two ends of the first flow chamber 6 are respectively connected to the second flow chamber 7 and the third flow chamber 8. An opening is provided in the left partition 3, and the second flow chamber 7 is connected to the installation chamber 5 through the opening. An air outlet pipe 9 is provided at the top of the cabin 1, and the lower end of the air outlet pipe 9 is connected to the side of the installation chamber 5 near the right partition 4. An air intake fan 10 is provided on the outer wall of the right side of the cabin 1, and the output end of the air intake fan 10 is connected to the third flow chamber 8 through the air intake hole 11. A controller is provided in the cabin 1, and the controller is electrically connected to the air intake fan 10.

[0034] The working principle and beneficial effects of the above technical solution are as follows: the temperature sensor is arranged in the installation cavity 5 of the cabin body 1, and the temperature sensor is electrically connected with the controller. The energy storage battery in the cabin body 1 can provide electric energy for the controller, the air inlet fan 10, the temperature sensor and the like. The installation cavity 5 is used for installing electric power equipment such as an inverter and a transformer. The temperature sensor is used for detecting the temperature in the installation cavity 5. When the temperature in the installation cavity 5 is higher than a preset maximum temperature, the controller controls the air inlet fan 10 to start. The air inlet fan 10 works to transport low-temperature air outside through the air inlet hole 11 to the third flow cavity 8. The temperature of the low-temperature air outside is lower than the temperature of the air in the installation cavity 5. Then, the low-temperature air flows downward along the third flow cavity 8. The low-temperature air enters the first flow cavity 6 and flows to the left along the first flow cavity 6. Then, the low-temperature air flows into the second flow cavity 7 on the left. The low-temperature air gradually flows upward in the second flow cavity 7. When the low-temperature air flows to the opening of the left partition plate 3, the low-temperature air enters the installation cavity 5 through the opening. Then, the low-temperature air flows through the electric power equipment in the installation cavity 5. The low-temperature air is fully mixed with high-temperature gas generated by the electric power equipment. The low-temperature air absorbs heat through heat exchange, thereby forming mixed gas flow with a rising temperature. As the temperature of the mixed gas flow rises, the mixed gas flow naturally flows upward and gathers. Finally, the mixed gas flow is discharged to the outside of the cabin body 1 through the air outlet pipe 9. New low-temperature air is continuously introduced into the cabin body 1 through the air inlet fan 10. The low-temperature air forms directional heat dissipation in the cabin body 1, thereby continuously reducing the temperature in the installation cavity 5. Compared with natural ventilation, the above scheme can actively introduce low-temperature air outside into the cabin body 1 through the air inlet fan 10. The low-temperature air directionally flows along the third flow cavity 8, the first flow cavity 6, the second flow cavity 7 and the installation cavity 5, thereby forming forced convection heat dissipation. The heat dissipation efficiency is improved. The temperature of the electric power equipment in the installation cavity 5 is reduced. The service life of the electric power equipment is prolonged. When the temperature in the installation cavity 5 is lower than a preset minimum temperature, the controller controls the air inlet fan 10 to be closed, thereby reducing unnecessary energy consumption and reducing the operation cost of the prefabricated cabin.

[0036] Based on the above embodiment 1, as shown in the drawings, the cabin door 12 is movably arranged on the front side of the cabin body 1. Figures 1-6

After the cabin door 12 is closed, the cabin door 12 plays a sealing role on the front side of the cabin body 1, avoiding the entry of external dust, rainwater and the like into the cabin body 1. When the power equipment in the installation cavity 5 needs to be overhauled, replaced or debugged, the cabin door 12 can be opened, so that the equipment can be directly contacted, and the maintenance of the power equipment can be completed without disassembling the structure of the cabin body 1. A plurality of support plates 13 are arranged in the installation cavity 5, and the power equipment can be installed on the support plates 13. The support plates 13 provide stable support for the power equipment. The number and spacing of the support plates 13 can be adjusted according to the size of the power equipment, the space utilization of the installation cavity 5 is improved, and gaps are ensured between the power equipment, which is beneficial to the flow of low-temperature air. The installation cavity 5 can be divided into multiple spaces from top to bottom by the multiple support plates 13, and the low-temperature air can be divided into multiple streams, so that the low-temperature air flows more uniformly through the surface of the power equipment, avoiding the flow of air due to the blockage of the power equipment. In addition, a plurality of air holes 14 are arranged in the support plates 13, and the low-temperature air below the support plates 13 can flow upward through the air holes 14, avoiding the stratification of the airflow due to the lower cold and the upper heat, enhancing the heat exchange effect, and the low-temperature air can fully contact the surface of the support plates 13 and the bottom of the power equipment when passing through the air holes 14, further absorbing the heat generated by the power equipment during operation. The mixed hot air is more easily gathered upward and quickly discharged through the air outlet pipe 9 at the top of the cabin body 1, thereby strengthening the overall heat dissipation effect.

Under the guidance of the guide plate 20 and the connecting plate 19, the divided low-temperature air flows flow into the corresponding guide strips 15 on one side, respectively. The guide strips 15 are distributed at equal intervals from front to back in the first flow cavity 6, which can provide stable support for the transverse partition plate 2 and guide the multiple low-temperature air flows to flow in the corresponding guide channels, and then flow into the second flow cavity 7 and flow into the mounting cavity 5 from the opening of the left partition plate 3. By arranging the partition plate 18, the connecting plate 19 and the guide strips 15, the low-temperature air flow can be uniformly dispersed, the air inlet amount of each area at the lower end of the second flow cavity 7 is uniform, the distribution of the low-temperature air flow in the mounting cavity 5 is more uniform in the front and rear areas, the blind area of heat dissipation caused by uneven distribution of air flow is reduced, and the heat dissipation effect is further improved.
