Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic base stations, and in particular to a self-cooling photovoltaic base station and a machine room. Background Art

[0002] As the number of base stations increases year by year, especially the use of 5G base stations, electricity consumption and electricity costs are increasing year by year, and the corresponding carbon emissions are also increasing year by year. Therefore, researching and building a computer room that can be powered by green energy has a positive significance for energy conservation, emission reduction, cost reduction and efficiency improvement. A photovoltaic base station is a communication base station powered by photovoltaic power generation technology. This type of base station works reliably, safely and without noise and other pollution. It has the advantages of simple installation and maintenance, low operating cost, suitable for unattended operation, good compatibility, and a wide range of availability. These advantages can largely solve the problem of power supply difficulties for base stations in remote areas.

[0003] The cabinets of existing photovoltaic base stations only dissipate heat through installed fan components, which consumes a lot of energy in the process of heat dissipation. In addition, traditional solar panels are installed in a rectangular distribution. When they are arranged and installed in a vertical space, as the sun moves, the shadows cast by the rectangularly distributed solar panels fall on the solar panels on the lower layer. This can only be alleviated by increasing the distance between the upper and lower layers of solar panels, which greatly reduces the number of layers of solar panels. Summary of the invention

[0004] The purpose of the present invention is to provide a self-cooling photovoltaic base station and a machine room to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The present invention is a self-cooling photovoltaic base station and a machine room, comprising a column, a transceiver antenna is installed on the top of the column, two columns are provided, at least one cross bar is installed between the two columns, a cabinet is installed on the cross bar, one side of the cabinet is provided with an inclined distributed battery panel, the battery panel is connected to the column through a mounting seat, and an exhaust duct is provided on the top of the cabinet, and the air flowing upward along the battery panel enters an air inlet of the exhaust duct.

[0007] Furthermore, the solar panel forms a triangular plate structure, and a tip of the inclined solar panel faces downward.

[0008] Furthermore, the main body of the cabinet is a cabinet body, which is fixedly mounted on a cross bar. Through slots are provided at both upper and lower ends of the cabinet body. A cabinet top connected to the interior of the cabinet body is installed on the through slot on the upper side. A fan group is installed in the air inlet end of the cabinet body. A cover body installed on the top of the cabinet body is provided on the outside of the cabinet top. The air outlet of the cover body and the air outlet of the cabinet top are located on the same side, and a filter mesh is installed in the through slot on the lower side.

[0009] Furthermore, an inclined corrugated plate is installed on the top of the cabinet roof.

[0010] Furthermore, the air outlet gradually shrinks from top to bottom.

[0011] Furthermore, the mounting seat is mainly composed of two semicircular clamp bodies, one end of the two clamp bodies is connected by a connecting block, and the other end is connected by a screw. A protrusion is provided in the middle of the convex surface of the clamp body, and a screw hole is opened on the protrusion, and a connecting piece is installed on the screw hole.

[0012] Furthermore, a ball head connecting column is provided at the end of the battery panel, and the connecting piece includes a ball head connecting seat and a ball head limiting seat, one end of the ball head connecting seat is a threaded column, and the other end of the ball head connecting seat is provided with a spherical groove, and a ball head limiting seat is installed on the port of the spherical groove, and the end of the ball head connecting column is limitedly installed between the spherical groove and the ball head limiting seat, and an opening is provided on the side of the ball head limiting seat, and the opening passes through the column of the ball head connecting seat and is limitedly fitted on the ball head.

[0013] Furthermore, notches are provided at both ends of the concave surface of the clamp body, protrusions are provided on the opposite sides of the notch, an anti-loosening part is installed in the notch, the anti-loosening part is limited by the notch, the anti-loosening part is a V-shaped spring piece, both ends of the anti-loosening part are corrugated ends, and the corrugated ends are located on the inner side of the concave surface of the clamp body.

[0014] Furthermore, the lower end of the solar panel is connected to the cross bar through a connecting rod.

[0015] Furthermore, a short rod is installed on one side of the two upright posts, and at least one mounting base connected to the lower end of the solar panel is installed on the short rod.

[0016] A machine room for a photovoltaic base station comprises a support pole installed on the ground, a frame is installed around the support pole, a power storage box is installed in the frame, the frame and power generation glass installed in the rectangular hole of the frame constitute the machine room, and an air intake fan group and an air outlet fan group are installed on opposite sides of the frame.

[0017] The present invention has the following beneficial effects:

[0018] 1. In the present invention, the wind blows along the inclined solar panels into the exhaust passage provided at the top of the cabinet, thereby taking away the hot air gathered at the top and realizing self-heating.

[0019] 2. The power generation surface of the tilted solar panels of the present invention faces the sun and generates electricity through sunlight. The tilt angle of the solar panels is adjusted according to the latitude of the installed solar panels. Compared with the traditional rectangular distributed solar panels, the triangular plate structure with the tip pointing downward has little effect on the lighting of the solar panels installed below in the vertical space as the sun moves, thereby increasing the power generation time of the solar panels located at the bottom.

[0020] 3. The present invention installs the solar panels on the pillars, which occupies a smaller area than the traditional installation on the ground. It does not need to harden a large amount of the bottom surface to install the solar panels, and the damage to the land is small. In addition, the photovoltaic panels installed on the ground also need to be regularly cleaned from the surrounding trees and weeds to prevent the trees and weeds from affecting the light. The solar panels installed on the pillars are stacked vertically and occupy a small space. At the same time, the installation position is high, the impact of trees and weeds on the light is small, and there is no need to clean the trees and weeds frequently.

[0021] 4. In the process of tightening the screws, the concave surface of the clamp body gradually approaches the outer surface of the column, squeezing the corrugated end between the two, so that the corrugated end gradually tends to be horizontal, completing the filling between the concave surface of the clamp body and the outer surface of the column, thereby increasing the friction between the contact surfaces of different components after installation, avoiding loosening of the installed mounting seat, and improving the bearing capacity of the mounting seat.

[0022] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Embodiment 1

[0040] like Figure 1-Figure 9 As shown, the present invention is a self-cooling photovoltaic base station and machine room, including a column 1, the bottom end of the column 1 is a connection end, the connection end is a connection flange, the connection flange is installed on a preset stud of an elongated support plate 9a, and the column 1 is fixed by a nut matched with the preset stud, and the elongated support plate is welded to the top of the support rod 10;

[0041] A transceiver antenna 6 is installed at the top of the column 1. The transceiver antenna 6 is installed on a bracket connected to the top of the column 1. The transceiver antenna 6 and the bracket are connected by bolts. The components in the transceiver antenna 6 can be replaced by removing the bolts later.

[0042] There are two columns 1, and at least one group of power generation components is installed between the two columns 1. The power generation components include a cross bar 2 installed between the two columns 1, a cabinet 3 installed on the cross bar 2, and a battery panel 4 obliquely distributed on one side of the cabinet 3, and the battery panel 4 is connected to the column 1 through a mounting seat 5;

[0043] The crossbar 2 and the column 1 are fixedly connected, and the connection method is any one of welding and fastening screw connection. The cabinet 3 is installed on the crossbar 2. The crossbar 2 and the cabinet 3 are both provided with connection holes for bolts. Bolts are installed in the corresponding connection holes between the crossbar 2 and the cabinet 3 to fix the cabinet 3;

[0044] At least a battery pack, an inverter, a DC meter, a CM510 DTU and an intelligent circuit breaker are installed in the cabinet 3. The cabinet 3 stores the electricity generated by the battery panel 4. After the electric energy in the cabinet 3 is fully stored, the generated electric energy is transmitted to the power storage box 12 through wires for storage;

[0045] In the process of powering the transceiver antenna 6, the battery pack in the cabinet 3 is preferentially used for powering;

[0046] A tilted battery panel 4 is provided on one side of the cabinet 3. The battery panel 4 is connected to the column 1 through a mounting base 5. The battery panel 4 forms a triangular plate structure, and a tip of the tilted battery panel 4 faces downward.

[0047] The solar panel 4 is provided with a plurality of triangular slots, and the triangular slots are correspondingly installed with power generation glass 402;

[0048] The power generation glass 402 is a cadmium telluride thin film solar cell, which is usually composed of five layers of materials: glass substrate, transparent conductive oxide layer, cadmium sulfide window layer, cadmium telluride absorption layer, back contact layer and back electrode;

[0049] Glass substrate: mainly acts as a support for the battery, prevents pollution and provides a lighting angle. The light transmittance of the ultra-white tempered glass must be higher than 91%;

[0050] Transparent conductive oxide layer: light transmission and conductivity;

[0051] Cadmium sulfide window layer: n-type semiconductor, forming a pn junction with the p-type cadmium telluride absorption layer;

[0052] Cadmium telluride absorption layer: It is the main light-absorbing layer of the battery. The pn junction formed with the n-type cadmium sulfide window layer is the core part of the entire battery.

[0053] Back contact layer: In order to reduce the contact barrier between cadmium telluride and the metal electrode, draw out current and make the metal electrode form ohmic contact with cadmium telluride.

[0054] The power generation surface of the tilted solar panels 4 faces the sun and generates electricity through sunlight. The tilt angle of the solar panels 4 is adjusted according to the latitude of the installed solar panels 4. Compared with the traditional rectangular solar panels, the triangular plate structure has a smaller impact on the illumination of the solar panels 4 installed below as the sun moves in the vertical space, thereby increasing the power generation time of the solar panels 4 located at the bottom.

[0055] The solar panels 4 are installed on the pillars 1. Compared with the traditional installation on the ground, the area occupied is smaller, and there is no need to harden a large amount of the bottom surface to install the solar panels, which causes less damage to the land. In addition, the photovoltaic panels installed on the ground also require regular cleaning of the surrounding trees and weeds to prevent the trees and weeds from affecting the light. The solar panels 4 installed on the pillars 1 are stacked vertically and occupy less space. At the same time, the installation position is high, so the impact of trees and weeds on the light is small, and there is no need to clean the trees and weeds frequently.

[0056] An exhaust passage is provided at the top of the cabinet 3, and the air flowing upward along the solar panel 4 enters an air inlet of the exhaust passage;

[0057] The installed solar panels 4 face the sun. In the northern hemisphere, the solar panels 4 face the south. In the hot summer, the summer wind blows from the Pacific Ocean in the southeast and the Indian Ocean in the southwest. The wind blows along the inclined solar panels 4 into the exhaust duct at the top of the cabinet 3, thereby taking away the hot air gathered at the top to achieve self-heating.

[0058] like Figure 3-Figure 5As shown, the main body of the cabinet 3 is a cabinet body 301, which is fixedly mounted on the cross bar 2. Through slots 3011 are provided at both upper and lower ends of the cabinet body 301. A cabinet top 302 connected to the interior of the cabinet body 301 is installed on the through slot 3011 on the upper side. A fan group 304 is installed in the air inlet end of the cabinet body 301. A cover body 303 installed on the top of the cabinet body 301 is provided on the outer side of the cabinet top 302. The air outlet of the cover body 303 and the air outlet of the cabinet top 302 are located on the same side. A filter mesh 305 is installed in the through slot 3011 on the lower side. An inclined corrugated plate 3021 is installed on the top of the cabinet top 302. The air outlet 3031 gradually shrinks from top to bottom.

[0059] When the cabinet 3 is performing heat dissipation work, the fan group 304 draws the hot air inside the cabinet body 301 into the cabinet top 302, and discharges it through the air outlet of the cabinet top 302. As the air outlet 3031 gradually shrinks from top to bottom, the air outlet formed between the air outlet 3031 and the cabinet top 302 gradually decreases. When the air intake volume remains unchanged, the wind speed between the air outlet 3031 and the cabinet top 302 increases, which helps to drive the air in the air outlet of the cabinet top 302 to be discharged, thereby reducing the working power of the fan group 304 and reducing the practical use of energy.

[0060] The top of the cabinet top 302 is a corrugated plate 3021. After the external air passes through the solar panel 4 and the cover 303, the corrugated plate 3021 increases the contact area, which is convenient for heat exchange with the hot air gathered at the top, thereby self-cooling the cabinet 301.

[0061] A filter mesh 305 is installed in the through slot 3011 at the lower side to filter dust in the incoming air;

[0062] A unidirectionally rotating plate can also be installed on the air outlet of the cabinet top 302. When the air in the cabinet top 302 is discharged, the plate is pushed to rotate upward, thereby facilitating air discharge. External air blows toward the plate, and the plate fits against the air outlet of the cabinet top 302 to achieve closure.

[0063] like Figure 7-Figure 9 As shown, the mounting base 5 is mainly composed of two semicircular clamp bodies 501 spliced ​​together, one end of the two clamp bodies 501 is connected by a connecting block 502, the connecting block 502 is a metal block with two through holes, the through holes of the connecting block 502 cooperate with the cylinder provided at the end of the clamp body 501, the clamp body 501 after installation rotates around the axis of the cylinder, and the other end is connected by a screw 504, a convex block is provided in the middle of the convex surface of the clamp body 501, a screw hole 5011 is provided on the convex block, a connecting piece is installed on the screw hole 5011, and a ball head connecting column 401 is provided at the end of the solar panel 4;

[0064] The connecting piece includes a ball head connecting seat 505 and a ball head limiting seat 506. One end of the ball head connecting seat 505 is a threaded column, and the other end of the ball head connecting seat 505 is provided with a spherical groove, and the ball head limiting seat 506 is installed on the end of the spherical groove.

[0065] The end of the ball head connecting column 401 is limitedly installed between the spherical groove and the ball head limiting seat 506;

[0066] During installation, the ball head of the ball head connecting column 401 is placed in the spherical groove of the ball head connecting seat 505, and the ball head limiting seat 506 is sleeved on the ball head and connected to the ball head connecting seat 505 by bolts, so as to limit the ball. After installation, the ball head connecting column 401 can also rotate to facilitate angle adjustment.

[0067] An opening is provided on the side of the ball head limiting seat 506, and the opening passes through the column of the ball head connecting seat 505 and is limitedly fitted on the ball head. Notches 5012 are provided at both ends of the concave surface of the clamp body 501, and protrusions 5013 are provided on the opposite sides of the notch 5012. An anti-loosening member 503 is installed in the notch 5012, and the anti-loosening member 503 is limited by the notch 5012. The anti-loosening member 503 is a V-shaped spring piece, and both ends of the anti-loosening member 503 are corrugated ends 5031, and the corrugated end 5031 is located on the inner side of the concave surface of the clamp body 501;

[0068] During installation, the anti-loosening member 503 is placed in the notch 5012, and the anti-loosening member 503 is placed through the protrusion 5013. The anti-loosening member 503 falls off during the installation process;

[0069] During the process of tightening the screw 504, the concave surface of the clamp body 501 gradually approaches the outer surface of the column 1, squeezing the corrugated end 5031 between the two, so that the corrugated end 5031 gradually tends to be horizontal, completing the filling between the concave surface of the clamp body 501 and the outer surface of the column 1, thereby increasing the friction between the contact surfaces of different components after installation, preventing the installed mounting seat 5 from loosening, and improving the bearing capacity of the mounting seat 5;

[0070] Compared with the existing method of adding rubber pads to prevent loosening, the anti-loosening component 503 is a steel sheet structure, and its practical life is longer than the service life of the rubber pad, which extends the maintenance cycle. By setting the end of the anti-loosening component 503 to a corrugated shape, after being squeezed, it tends to return to its original position due to the elastic memory of the steel sheet, thereby increasing the squeezing of the contact surface, effectively increasing the friction force, and improving the reliability of installation.

[0071] The lower end of the solar panel 4 is connected to the cross bar 2 via a connecting rod 7 , and the bottom end of the solar panel 4 is supported by the connecting rod 7 , thereby improving the installation reliability of the solar panel 4 .

[0072] Embodiment 2

[0073] like Figure 10-11 As shown, the differences from the first embodiment are as follows:

[0074] The bottom end of the column 1 is a connection end, and the connection end is a connection flange, which is installed on the preset studs of the triangular support plate 9b, and the column 1 is fixed by nuts matched with the preset studs. The elongated support plate is welded to the top of the support rod 10, and the support rod 10 is installed on the ground. A frame 11 is installed around the support rod 10, and a power storage box 12 is installed in the frame 11;

[0075] A short rod 8 is installed on one side of the two upright posts 1 , and at least one mounting seat 5 connected to the lower end of the solar panel 4 is installed on the short rod 8 .

[0076] When in use, the lower end of the solar panel 4 is supported by the short rod 8 to improve the supporting strength. In addition, the short rod 8 and the two columns 1 are arranged along a triangle and connected by the solar panel 4 and the mounting seat 5 to avoid shaking and increase the overall strength of the structure.

[0077] Embodiment 3

[0078] like Figure 10-11 As shown, the differences from Embodiment 1 and Embodiment 2 are as follows:

[0079] A photovoltaic base station machine room includes a support pole, wherein the support pole 10 is installed on the ground, a frame 11 is installed around the support pole 10, a power storage box 12 is installed in the frame 11, the frame 11 and the power generation glass installed in the rectangular hole of the frame 11 constitute the machine room, and an air intake fan group 13 and an air outlet fan group 14 are installed on opposite sides of the frame 11, and the air on the top floor of the machine room is driven to be discharged by the air outlet fan group 14 to achieve the purpose of heat dissipation;

[0080] By renovating the machine room, increasing the installation area of ​​the power-generating glass, and installing cadmium telluride power-generating glass, the power generation in the power-generating glass machine room can be achieved with "self-generation for own use + storage of surplus electricity".

[0081] The power generation glass uses cadmium telluride power generation glass, which is a new type of energy-saving, efficient, stable and environmentally friendly material. It is generally used in the exterior walls, roofs, curtain walls, etc. of buildings to provide clean energy for the buildings. This technology is horizontally applied to communication rooms, which can not only reduce pollution, save energy and reduce emissions, and improve resource utilization;

[0082] A battery pack is placed in the power storage box 12, and energy is stored through the battery pack;

[0083] Power generation glass can be installed on the outside of the frame 11 to increase the installation area of ​​the solar power generation equipment. In addition, the power generation glass is more beautiful than the traditional solar cell panel and can be installed on the bottom layer for decoration.
