Description

Technical Field

[0001] This utility model relates to the technical field of skid-mounted equipment rooms in oil and gas stations, and in particular to a photovoltaic support structure and roof. Background Technology

[0002] Skid-mounted equipment refers to a complete system (including equipment, pipelines, valves, instruments, etc.) that performs a specific function, integrated onto a single base. During long-distance pipeline transportation, to ensure the safe operation of production equipment, control equipment is typically placed in skid-mounted equipment rooms to prevent external environmental factors from reducing its service life. Skid-mounted equipment rooms are characterized by their compact design, small footprint, and convenient installation, and are widely used in oil and gas stations and valve chamber technology.

[0003] To accelerate the integration of energy conservation, environmental protection, and industrial development, the installation of photovoltaic (PV) modules in skid-mounted equipment rooms has become a trend. This effectively utilizes renewable solar energy and ensures operational safety in emergency situations when the power system fails. However, the main problems currently are: 1. Currently, the base of the PV support is fixed to the roof of the skid-mounted equipment room via bolt holes. These holes are prone to leaks or damage to the roof, allowing rainwater to enter the equipment room, affecting normal equipment operation or causing corrosion. 2. Skid-mounted equipment rooms are usually equipped with data acquisition devices to collect environmental parameters. Inadequate corrosion protection and sealing after PV support installation may lead to errors in temperature, humidity, and gas concentration monitoring. 3. Currently, most PV support installations in skid-mounted equipment rooms are done on-site. The installation angle of the PV module receiving surface is difficult to control, increasing the risk of tipping over or falling accidents for the PV support and installation personnel. The installation process is also time-consuming and labor-intensive. In summary, the current use of PV in skid-mounted equipment rooms presents certain safety hazards and production risks. Therefore, it is essential to explore an improvement method that can both ensure the safe operation of equipment in skid-mounted equipment rooms and effectively utilize PV power generation technology.

[0004] Currently, the main solutions to these problems are standardizing the installation procedures for photovoltaic (PV) brackets, ensuring tight connections at cable and bracket drilling points, and applying waterproofing and corrosion protection to exposed metal connections. Building-integrated photovoltaics (BIPV), from its design concept to its application technology, has become increasingly mature, providing a new approach to utilizing PV systems in skid-mounted installations by combining building rooftops with PV systems.

[0056] The roof of the skid-mounted equipment room adopts a prefabrication process, and the roof structure of the skid-mounted equipment room is designed with photovoltaic integration. The design includes roof structure modules, roof installation modules, roof and photovoltaic integration modules, and photovoltaic module modules.

[0057] 1. Roof structure module

[0058] The main requirements for the roof structure of skid-mounted equipment rooms in oil and gas stations include: meeting the requirements for thermal insulation, heat dissipation, waterproofing, and fireproofing under various environmental conditions; withstanding dead loads, seismic loads, and wind loads, and meeting corresponding deformation requirements. The main components of the overall roof structure include the roof surface, insulation layer, load-bearing structure, and photovoltaic modules. See the roof structure diagram and material requirements as specified. Figure 3 .

[0059] Specifically, the roof structure is as follows: (1) The roof adopts a welded integrated structure, and the frame is made of welded steel sections. The steel is usually Q235B, and the welding rod type is E43. The top cover of the hull has a slope of not less than 5%, and the roof adopts a single-slope drainage method.

[0060] (2) The roof outer panel shall be made of high-quality seamless stamped roof panel (profiled steel sheet) with a thickness of not less than 2mm, and the material shall be corrosion-resistant metal (including galvanized steel, weathering steel, stainless steel, etc.).

[0061] (3) The inner side of the roof is reinforced with thermal insulation rock wool board (outer board, rock wool, inner board), wherein the outer board is 0.6mm thick (galvanized steel sheet) + 100mm thick rock wool + the inner board is 0.6mm thick (galvanized steel sheet), and a composite thermal insulation material is installed in the interlayer. The thermal conductivity should not exceed 0.04W / (m·K) at an average temperature of 298K, and the density should not exceed 100kg / m³. 3 The steel plate primer is epoxy resin, and the outdoor coating is gray and the indoor coating is white high-weather-resistant polyester. The coating thickness is ≥20μm on the outer surface and ≥10μm on the inner surface.

[0062] (4) The exterior of the roof is equipped with hybrid HIT (Heterojunction with intrinsic Thinlayer) photovoltaic panels.

[0063] 2. Roof-mounted module

[0064] Photovoltaic modules installed in the southeast or southwest direction have higher solar energy collection efficiency than those installed in the northeast or northwest direction. In northern regions, the optimal tilt angle between the photovoltaic panels and the horizontal plane is between 25° and 50°, while in southern regions it is between 15° and 35°. The overall roof structure can be designed as a sloping roof based on this angle range, depending on the specific location, which facilitates roof drainage and maximizes the solar energy output of the photovoltaic panels from the southeast and southwest directions.

[0065] The roof installation employs a concealed purlin arrangement, coupled with dedicated waterproof photovoltaic (PV) brackets. These brackets are fixed to the roof purlins. Appropriate insulating rock wool panels (outer panel, rock wool, and inner panel) are laid on the waterproof brackets and secured to the brackets with other fasteners. High-quality seamless stamped steel sheets (profiled steel sheets) are then installed on the insulating rock wool panels, with the PV modules installed on the top layer. A key aspect of roof installation is considering the increased roof load caused by the installation of the PV panels (PV modules). Because the integrated PV roof structure is prefabricated in the factory, it facilitates the selection and calculation of steel structure materials.

[0066] 3. Rooftop and photovoltaic integrated modules

First, the first row of edge and center fasteners are installed to secure the first stamped steel plate. Then, the second row of fasteners is installed and secured, with the stamped steel plates sequentially pressed onto the previous plate. This process is repeated until the edges are finished using an automatic seam locking machine. The "T"-shaped fasteners are connected to the photovoltaic modules via seam clamps 203. The connection method is described in [details omitted]. Figure 1 and Figure 2 .

[0068] 4. Photovoltaic support structure modules

[0069] The support structure (photovoltaic support) mainly adopts a longitudinal profiled steel sheet arrangement with W-shaped water guide channels. First, the locking clips above the W-shaped water guide channels are connected with bolts. Square nuts are then placed above the cavities of the water guide channels and tightened to secure them. Photovoltaic modules 108 are then laid between the locking clips on both sides. Friction grooves 306 are present between the bottom surface of the photovoltaic module 108 and the locking clips 203 to increase horizontal friction. Buffer rubber strips 304 are placed between photovoltaic modules 108, and pressure rubber pads 307 are placed between the sides of the photovoltaic module 108 and the W-shaped water guide channels to reduce and buffer impacts from all sides. The overall vibration damping capability of the photovoltaic modules 108 ensures the stable operation of the entire photovoltaic panel. (See...) Figure 2 .
