[0002] Distributed photovoltaic power generation refers to a distributed power generation system that uses photovoltaic modules to directly convert solar energy into electrical energy. It is a new type of power generation and comprehensive energy utilization method with broad development prospects. It advocates the principle of nearby power generation, nearby grid connection, nearby conversion, and nearby use. It can not only effectively increase the power generation of photovoltaic power stations of the same scale, but also effectively solve the problem of power loss in voltage boosting and long-distance transportation. In order to ensure the stable operation of distributed photovoltaic power generation, people install prefabricated substations in photovoltaic power plants.

[0003] However, in actual use, since photovoltaic power generation is usually located in the wild or in farmland and grassland, and since the power consumption of the substation is large, it generates a lot of heat when working. Therefore, it is necessary to set a ventilation structure at the bottom of the device. The bottom ventilation structure needs to avoid the intrusion of rainwater in rainy and snowy weather, so the device needs to have a higher support platform and blocking components. Based on this, a prefabricated photovoltaic power generation substation is proposed. Utility Model Content

[0004] The utility model aims to provide a photovoltaic power generation prefabricated substation, which solves the problem that the existing substation needs to be able to facilitate ventilation and cooling, and needs to be able to conveniently block the entry of debris and rainwater.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a photovoltaic power generation prefabricated substation, comprising a cabinet, a support block and a fixing plate, wherein the bottom ends of the cabinet are provided with support blocks, the bottom of the cabinet is provided with a fixing plate, the bottom of the fixing plate is provided with a wind shield, and the bottom center of the wind shield is provided with a wind guide strip;

[0007] A plurality of driving fans are installed on both sides of the interior of the fixed plate for support, and the top of the driving fan is connected to the bottom of the cabinet;

[0008] Both sides of the top of the wind guide strip used for blocking are inclined toward the bottom, the two ends of the two support blocks are connected by a blocking plate, and the top of the blocking plate rotates with the support block through a rotating shaft.

[0009] Preferably, a plurality of filter holes are provided in an array on the side wall of the blocking plate near the bottom end of the wind shield plate, and the top end of the side wall of the blocking plate is in contact with one side of the fixing plate.

[0010] Preferably, a mounting hole corresponding to the driving fan is opened inside the fixing plate, both ends of the fixing plate are fixed to the supporting block, and a plurality of air inlets are opened on both sides of the windshield plate at positions corresponding to the driving fan.

[0011] Preferably, both ends of the wind shield are fixed to the support blocks, the side wall of the wind shield is tightly fitted with one side of the blocking plate, and a cover plate is fitted on the top of the wind shield near the air inlet.

[0012] Preferably, the bottom of the air inlet is inclined toward the center of the wind shield, and the cover plate is rotatably connected to the wind shield via a rotating shaft at an edge close to the wind shield.

[0013] Preferably, a through hole corresponding to the inside of the driving fan is opened at the bottom of the cabinet, air outlets are opened near the top of the two side walls of the cabinet, and the top of the cabinet is connected to a top plate.

[0014] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0015] 1. The filter holes can effectively block external debris and prevent larger organisms from reaching the bottom of the windshield. When in use, the gas passes through the gaps between multiple isolation strips to prevent rainwater from flowing in directly. At the same time, since the bottom of the cabinet is supported by support blocks and the bottoms of the support blocks are connected, it is very convenient for rainwater to flow away and avoid excessive rainwater accumulation and backflow.

[0016] 2. Start the driving fan, so that the driving fan rotates and actively drives the air at the bottom to the top, so that the gas can pass through the rectangular hole more quickly, and then be transported to the inside of the cabinet through the gap between the isolation strips. At the same time, when the power of the driving fan is large, it can also drive the cover on the top of the air inlet to rotate and open, so that the external gas can directly reach the bottom of the driving fan through the bottom air inlet, and then be transported to the inside of the cabinet, which is more convenient and quick, and improves the heat dissipation efficiency.

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] The utility model provides Figure 1-5 A photovoltaic power generation prefabricated substation shown in the figure includes a cabinet 1, a support block 2 and a fixed plate 3. Support blocks 2 are arranged at both ends of the bottom of the cabinet 1, a fixed plate 3 is arranged at the bottom of the cabinet 1, a wind shield 4 is arranged at the bottom of the fixed plate 3, and a wind guide strip 6 is arranged at the bottom center of the wind shield 4; a rectangular hole 401 is opened at the center of the wind shield 4 for guiding the airflow, and a plurality of isolation strips 5 are arranged on the top of both sides of the rectangular hole 401, and the plurality of isolation strips 5 are staggered and fixed to the top of the wind shield 4 and the bottom of the fixed plate 3 respectively; a plurality of driving fans 301 are installed on both sides of the fixed plate 3 for support, and the top of the driving fan 301 is connected to the bottom of the cabinet 1.

[0027] like Figure 1-5 As shown, both sides of the top of the wind guide strip 6 used for blocking are inclined toward the bottom, the two ends of the two support blocks 2 are connected by a blocking plate 201, and the top of the blocking plate 201 rotates with the support block 2 through a rotating shaft, and a plurality of filter holes 202 are arranged in an array on the side wall of the blocking plate 201 near the bottom end of the wind shield 4, and the top of the side wall of the blocking plate 201 is in contact with one side of the fixed plate 3.

[0028] During use, when the air reaches one side of the bottom of the cabinet 1, it can pass through the filter hole 202 at the bottom of the blocking plate 201, and then be guided by the wind guide strip 6 to move to the top, and then pass through the gaps between the staggered isolation strips 5 to reach the bottom position of the driving fan 301, so as to conveniently reach the interior of the cabinet 1 through the driving fan 301 to achieve cooling, and then be discharged through the air outlet 102 on the top. The blocking of the filter hole 202 can effectively block external debris, and can also prevent larger organisms from reaching the bottom of the wind shield 4. Moreover, when in use, the gas passes through the gaps between multiple isolation strips 5, which can also prevent rainwater from directly flowing in. At the same time, since the two ends of the bottom of the cabinet 1 are supported by the support blocks 2, and the bottoms between the support blocks 2 are connected, and the center of the wind guide strip 6 is raised, it can facilitate the flow of rainwater, avoid the accumulation of more rainwater, and prevent rainwater from flowing back through the rectangular hole 401.

[0029] like Figure 4 , Figure 5 As shown, the interior of the fixing plate 3 is provided with a mounting hole 302 corresponding to the driving fan 301, the two ends of the fixing plate 3 are fixed to the supporting block 2, and a plurality of air inlets 402 are provided on both sides of the wind shield 4 at positions corresponding to the driving fan 301, both ends of the wind shield 4 are fixed to the supporting block 2, the side wall of the wind shield 4 is tightly fitted with one side of the blocking plate 201, and a cover plate 403 is fitted at the top of the wind shield 4 near the air inlet 402, the bottom of the air inlet 402 is inclined toward the center of the wind shield 4, and the cover plate 403 is rotatably connected to the wind shield 4 through a rotating shaft at the edge of the wind shield 4.

[0030] like Figure 1 , Figure 3 As shown, a through hole corresponding to the inside of the driving fan 301 is opened at the bottom of the cabinet 1, air outlets 102 are opened near the top of the two side walls of the cabinet 1, and the top of the cabinet 1 is connected to the top plate 101.

[0031] The driving fan 301 can be started, so that the driving fan 301 rotates and actively drives the air at the bottom to the top, so that the gas can pass through the rectangular hole 401 more quickly, and then be transported to the inside of the cabinet 1 through the gap between the isolation strips 5. At the same time, when the power of the driving fan 301 is large, the cover 403 on the top of the air inlet 402 can be driven to rotate and open through suction, so that the external gas can directly reach the bottom of the driving fan 301 through the bottom air inlet 402, and then be transported to the inside of the cabinet 1, which is more convenient and quick, and improves the heat dissipation efficiency. The blocking plate 201 can also be rotated to open, so that the bottom space of the fixing plate 3 is connected to the outside, which can further facilitate the gas to be transported to the cabinet 1 through the driving fan 301, thereby achieving efficient heat dissipation.

[0032] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
