[0024] The technical solution protected by the utility model is described in detail below with reference to the accompanying drawings.

[0025] like Figure 1 As shown, the present application provides a waterproof photovoltaic base, which includes a supporting base 100 and waterproof pressure pieces 200 arranged on both sides of the supporting base 100, the supporting base 100 and the waterproof pressure pieces 200 are locked and connected by bolts 300, the waterproof pressure pieces 200 fix the supporting base 100 on the roof, and the supporting base 100 is used to support photovoltaic panels.

[0026] like Figure 1-3 As shown, the support base 100 includes a base portion 110, a water guide portion 120 and a supporting portion 130 arranged in sequence from bottom to top, and the support base 100 is used to provide hardness support for the support of the photovoltaic panel. The support base 100 is an integrated structure, which effectively improves the hardness of the support base 100. In this embodiment, the support base 100 uses aluminum profiles to ensure that the photovoltaic base has the supporting strength and can stably support the photovoltaic panel. A shielding space is formed between the base portion 110 and the water guide portion 120 for accommodating the waterproof pressure piece 200.

[0027] like Figure 1-3 As shown, the base part 110 is placed on the roof to provide basic support force. The base part 110 includes a base bottom plate 111, which can be placed on the roof to ensure that the support base 100 can be stably placed on the roof. The two sides of the base bottom plate 111 are provided with oppositely arranged base side plates 112, and two groups of waterproof pressure pieces 200 are respectively connected to the two base side plates 112 by bolt locking. Preferably, the upper ends of the two base side plates 112 extend toward each other and form an eight-shaped structure. The waterproof pressure pieces 200 on both sides are correspondingly pressed on the two base side plates 112, and a downward pressing force is applied to the base side plates 112, and the support base is stably fixed on the roof by the waterproof pressure pieces.

[0028] like Figure 1-3As shown, the water guide part 120 is correspondingly arranged above the base part 110, and the water guide part 120 includes a shielding bottom plate 121 arranged at the upper end of the base side plate 112, and the shielding bottom plate 121 has a relatively arranged flow guide side plate 122 on both sides of the corresponding base side plate 112. The horizontal width of the shielding bottom plate 121 is greater than the horizontal distance between the upper ends of the two base side plates 112, so that a shielding space is formed between the water guide part 120 and the base part 110, and the waterproof pressure piece 200 is correspondingly placed in the shielding space. The shielding bottom plate 121 is correspondingly placed above the waterproof pressure piece 200, and covers the waterproof pressure piece 200, effectively preventing rainwater from falling between the support base 100 and the waterproof pressure piece 200. The upper ends of the two guide side plates 122 extend toward each other in an eight-shaped structure, which can guide the water flow, guide the rainwater to flow away from the support base 100, and effectively prevent the water flow from directly flowing into the installation gap between the support base 100 and the waterproof pressure piece 200.

[0029] like Figure 1-3 As shown, the supporting part 130 is correspondingly placed at the upper end of the water guide part 120, and the supporting part 130 includes two relatively upright supporting plates 131, and the upper end of the supporting plate 131 is provided with a horizontally placed supporting plate 132. The photovoltaic panel is correspondingly placed on the supporting plate 132 to increase the supporting area of ​​the supporting plate 132 and improve the supporting stability.

[0030] like Figure 1-3 As shown, the waterproof pressure piece 200 includes an L-shaped pressure plate 210 and a pressure plate fixing piece 220. Bolts pass through the L-shaped pressure plate 210 and the supporting base 100 inward from the pressure plate fixing piece 220 in sequence, and the supporting base 100 is locked and connected with the L-shaped pressure plate 210. It is not only convenient to operate and disassemble, but also has a firm and reliable connection. The fixed connection between the photovoltaic base and the roof is then completed through the L-shaped pressure plate 210.

[0031] like Figure 1-3 As shown, the L-shaped pressing plate 210 includes a pressing portion 211 and a connecting portion 212. The pressing portion 211 is pressed onto the base side plate 112 through a pressing plate fixing piece 220, and the connecting portion 212 is used to connect to the roof, so as to fix the photovoltaic base on the roof. In this embodiment, the connecting portion 212 is correspondingly hot-melt welded to the roof to improve the connection stability, and will not damage the waterproof layer of the roof, thereby effectively improving the waterproof performance. The pressing portion 211 and the connecting portion 212 are an integrally formed structure, and TPO material is selected to achieve sealing and waterproofing, prevent rainwater from leaking from the connection between the pressing portion 211 and the connecting portion 212, and effectively improve the waterproof performance. Among them, the pressing portion 211 is pressed and fitted onto the base side plate 112, and the L-shaped pressing plate covers the connection between the base side plate 112 and the roof, effectively preventing water from seeping in.

[0032] like Figure 1-3As shown, the pressing plate fixing member 220 is pressed on the side of the pressing part 211 away from the supporting base 100, so as to enhance the connection stability between the L-shaped pressing plate 210 and the supporting base 100. The upper end of the pressing plate fixing member 220 is correspondingly provided with a bending portion 221, which is bent toward the supporting base 100, so that the pressing part 211 of the L-shaped pressing plate 210 is correspondingly placed below the bending portion 221. The bending portion 221 cooperates with the water guide portion 120 to cover the pressing part 211, which not only beautifies the appearance, but also realizes the function of shielding rain, preventing rainwater from leaking from the gap between the supporting base 100, the L-shaped pressing plate 210 and the pressing plate fixing member 220, and plays a role in waterproofing and leakage. Preferably, the outer side wall of the bending portion 221 is set as an inclined slope, and the lower end of the bending portion 221 is inclined in a direction away from the supporting base 100 to guide rainwater and effectively prevent rainwater from accumulating on the pressure plate fixing member 220.
