Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic devices on building flexible roofs, and in particular to a distributed photovoltaic system suitable for flexible roofs of steel structure workshops. Background Art

[0002] As environmental awareness continues to increase, more and more people choose to install photovoltaic panels on industrial and commercial roofs to reduce building energy consumption and protect the ecological environment.

[0003] At present, flexible roof structures are mainly used to install photovoltaic power stations. The traditional flexible roof structure is mainly composed of an insulation layer, a waterproof membrane and a bracket, wherein the insulation layer is bonded and laid on the roof; the waterproof membrane is bonded and laid on the insulation layer; the bracket is fixed on the waterproof membrane; and the photovoltaic panel is fixedly connected to the bracket.

[0004] In actual use, the above structure can absorb solar energy and provide electricity for the building. However, the insulation layer, waterproof membrane, bracket and photovoltaic panel are all connected by bonding, which not only makes it difficult to find local damage to the insulation layer or waterproof membrane, but also makes it difficult to repair the locally damaged insulation layer or waterproof membrane, which greatly increases the operation and maintenance costs. Photovoltaic panels generate a lot of heat while generating electricity. If hot spots are formed on photovoltaic panels, it will cause the flexible roof to catch fire, affecting the safety of the flexible roof structure.

[0005] Therefore, how to design a distributed photovoltaic system suitable for the flexible roof of a steel structure factory building is an urgent problem that technicians in this field need to solve. Summary of the invention

[0006] The present invention provides a distributed photovoltaic system suitable for the flexible roof of a steel structure factory building, which solves the technical problems of the traditional flexible roof installation photovoltaic power station being difficult to repair, difficult to repair, posing fire safety hazards and reducing operation and maintenance costs.

[0007] The technical solution of the present invention to solve the above technical problems is as follows: a distributed photovoltaic system suitable for a flexible roof of a steel structure factory building, wherein a plurality of roof purlins are fixed at intervals on the flexible roof; a thermal insulation layer is laid on the plurality of roof purlins; a waterproof coiled material is laid on the thermal insulation layer; the system comprises: a plurality of "X"-shaped connectors, a plurality of "X"-shaped purlins, a plurality of fixing seats, a fixing plate, a plurality of photovoltaic clamps, a plurality of photovoltaic rails, a plurality of photovoltaic panels and a plurality of photovoltaic pressure plates,

[0008] The insulation layer and the waterproof membrane are provided with a plurality of through fixing holes, and the plurality of fixing holes are respectively arranged opposite to the plurality of roof purlins; the plurality of I-shaped connecting members are respectively placed in the plurality of fixing holes and are detachably connected to the corresponding roof purlins; the plurality of I-shaped purlins are respectively detachably connected to the plurality of I-shaped connecting members; the plurality of fixing seats are respectively detachably connected to the plurality of I-shaped purlins; the fixing plate is laid on the plurality of fixing seats and is detachably connected to the plurality of fixing seats; the plurality of photovoltaic clamps are detachably connected to the fixing plate at intervals; the plurality of photovoltaic rails are respectively detachably connected to the plurality of photovoltaic clamps; the plurality of photovoltaic panels are laid on the plurality of photovoltaic rails at intervals; each of the photovoltaic pressure plates is respectively pressed on the opposite edges of the two adjacent photovoltaic panels and is detachably connected to the corresponding photovoltaic rails.

[0009] The beneficial effects of the present invention are:

[0010] 1. Multiple "X"-shaped connectors are placed in multiple through fixing holes and detachably connected to the corresponding roof purlins. The stability of the connection between the insulation layer and the waterproof membrane can be maintained without using glue to bond them, which provides convenience for the subsequent repair of the insulation layer or the waterproof membrane;

[0011] 2. First, use multiple "J"-shaped purlins to fix them on multiple "J"-shaped connectors, and then use multiple fixing seats to fix them on multiple "J"-shaped purlins, and finally lay and fix the fixing plates on multiple fixing seats. This can isolate the fixing plates and waterproof membranes, maintain the thermal insulation performance of the original roof, and add an additional metal roof waterproofing to improve the waterproof performance of the roof. At the same time, it prevents the photovoltaic panels from contacting the original roof, and prevents the photovoltaic panels from spontaneously igniting the original roof;

[0012] 3. The "J"-shaped connectors, "J"-shaped purlins, fixing seats, fixing plates, photovoltaic clamps, photovoltaic rails, photovoltaic panels and photovoltaic pressure plates are all detachably connected by bolts, which can facilitate later maintenance;

[0013] 4. By pressing each photovoltaic pressure plate on the edge between two adjacent photovoltaic panels, the stability and firmness of the photovoltaic panel installation can be improved.

[0014] Based on the above technical solution, the present invention can also be improved as follows.

[0015] Furthermore, it also includes a plurality of pieces of thermal insulation cotton, and the plurality of pieces of thermal insulation cotton are respectively filled in the plurality of the X-shaped connecting parts.

[0016] A further beneficial effect of the above method is that by filling a plurality of "X"-shaped connectors with a plurality of pieces of thermal insulation cotton, the thermal insulation performance of the original roof can be maintained.

[0017] Furthermore, a plurality of fixing grooves are provided on the bottom surface of the fixing plate; the plurality of fixing seats extend into the plurality of fixing grooves respectively and are fixed at the bottoms of the corresponding fixing grooves.

[0018] A further beneficial effect of the above method is that by using multiple fixing seats to be respectively embedded in multiple fixing grooves, the overall height can be reduced and the stability of the structure can be improved.

[0019] Furthermore, the fixing plate is made of a corrosion-resistant and durable zinc-aluminum-magnesium alloy material. BRIEF DESCRIPTION OF THE DRAWINGS
