They do not indicate or imply that the device or unit referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as a limitation on the present invention.

[0028] like Figure 1 to Figure 6 As shown, this embodiment discloses a waterproof fixing bracket for a photovoltaic panel, including a water tank 1 and a support plate 3 arranged on the water tank 1. The number of the water tanks 1 is multiple, and the water tanks 1 are distributed parallel to each other. The water tanks 1 are arranged below the long side of the photovoltaic panel 7.

[0029] refer to Figure 3 to Figure 5 As shown, the support plate 3 is used to abut the frame 71 of the photovoltaic panel 7. Specifically, the frame 71 is provided with a bottom plate 72 abutting against the support plate 3. The bottom plate 72 is spaced apart from the frame 71 and is located below the photovoltaic panel 7 and the frame 71.

[0030] The support plate 3 is provided with a protrusion 32 and a baffle 35, wherein the protrusion 32 is located in the middle of the support plate 3, and the baffles 35 are distributed on both sides of the protrusion 32. The support plate 3 is also provided with abutment plates 31 located on both sides of the protrusion 32, and the abutment plates 31 connect the protrusion 32 and the baffle 35. The bottom plate 72 abuts downward on the abutment plates 31, and the bottom plate 72 is arranged between the protrusion 32 and the baffle 35, and then the left and right movement of the bottom plate 72 is limited by the protrusion 32 and the baffle 35 to ensure the stable and reliable installation of the photovoltaic panel 7.

[0031] A pressure block 4 is fixed on the support plate 3. Specifically, a second mounting hole 33 is provided on the support plate 3, and a through hole 42 corresponding to the position of the second mounting hole 33 is provided on the pressure block 4. An external bolt can pass through the through hole 42 and be tightened on the second mounting hole 33, thereby pressing and fixing the pressure block 4 on the support plate 3.

[0032] The pressing plate 41 of the pressing block 4 is pressed against the bottom plate 72. The pressing plates 41 are arranged on both sides of the pressing block 4 and correspond to the abutment plates 31 one by one. The pressing plates 41 can press the bottom plate 72 downward, that is, press the bottom plate 72 against the abutment plate 31, and then press the bottom plate 72 of the fixed frame 71 downward through the pressing plate 41, so that the frame 71 (photovoltaic panel 7) is fixed and limited on the support plate 3, that is, the photovoltaic panel 7 can be installed and fixed without drilling holes, which makes the installation of the photovoltaic panel 7 more convenient and improves the installation efficiency of the photovoltaic panel 7. At the same time, it also avoids the situation where the structural strength of the photovoltaic fixed bracket is reduced due to drilling, and also improves the reliability of the installation and use of the photovoltaic panel 7.

[0033] Furthermore, a convex plate 721 is provided on the bottom plate 72, and the convex plate 721 extends upward to between the protrusion 32 and the pressure plate 41, and a certain installation gap is left between the convex plate 721 and the pressure plate 41. Through the above-mentioned installation gap design, the installation and cooperation between the pressure block 4 and the frame 71 are more convenient.

[0034] Specifically, the convex plate 721 is first set in contact with the convex block 32, and then the pressure block 4 is fixed on the support plate 3. Due to the setting of the above-mentioned installation gap, when the pressure block 4 is installed, there will be no installation interference such as abutment between the pressure plate 41 and the convex plate 721, that is, the pressure plate 41 can be quickly pressed downward on the bottom plate 72, and at this time, the convex plate 721 is located between the convex block 32 and the pressure plate 41.

[0035] The convex plate 721 is limited by cooperating with the protrusion 32 and the pressure plate 41, thereby achieving installation limitation of the frame 71 (i.e., the photovoltaic panel 7), improving the installation stability of the photovoltaic panel 7, and avoiding problems such as large shaking of the photovoltaic panel 7 in windy weather.

[0036] The pressing block 4 is provided with a fixing member 5 and a cover plate 6. The fixing member 5 is provided with a second through hole 52 corresponding to the position of the second mounting hole 33. The external bolts pass through the second through hole 52 and the first through hole 42 in sequence and are tightened and fixed in the second mounting hole 33 to fix the fixing member 5 on the pressing block 4.

[0037] Furthermore, a groove 43 is provided at the upper end of the pressing block 4, and a convex strip 53 corresponding to the position of the groove 43 is provided on the fixing member 5. The convex strip 53 is snapped into the groove 43 to position the fixing member 5 when it is installed on the pressing block 4, so as to facilitate the placement and fixation of the fixing member 5.

[0038] An extension plate 1 51 and an extension plate 2 61 corresponding to each other are arranged between the fixing member 5 and the cover plate 6. The number of the extension plate 1 51 and the extension plate 2 61 are both two. The two extension plates 1 51 extend upward between the two extension plates 2 61. A clamping strip 1 511 is arranged on the extension plate 1 51, and a clamping strip 2 611 corresponding to the clamping strip 1 511 is arranged on the extension plate 2 61. The clamping strip 1 511 and the clamping strip 2 611 abut against each other to fix the fixing member 5 and the cover plate 6.

[0039] The cover plate 6 is provided with side plates 62 on both sides thereof which are fitted on the upper end surface of the frame 71 . The side plates 62 are fitted on the upper end surface of the frame 71 to prevent external dust from entering between two adjacent photovoltaic panels 7 , that is, the cover plate 6 plays a certain dustproof role.

[0040] The water tank 1 is provided with a slide bar 11 distributed along its length direction, and the support plate 3 is provided with a T-slot 2 34 adapted to the slide bar 11. The support plate 3 can slide along the length direction of the slide bar 11. When the support plate 3 needs to be fixed, the external bolt is tightened through the mounting hole 2 33 and abuts against the slide bar 11 to fix the support plate 3. Then, the support plate 3 can be adjusted to a corresponding position on the slide bar 11 according to actual conditions, that is, the support plate 3 can be adjusted to the required fixed position on the frame 71 to fix the photovoltaic panel 7, and there is no need to drill holes on the water tank 1 to fix the support plate 3, so that the installation requirements of photovoltaic panels 7 of different sizes can be met, thereby improving the practicability of the bracket for installing the photovoltaic panel 7.

[0041] refer to Figure 2 , Figure 6 As shown, a fastener 2 is provided on the slide bar 11, and a T-slot 23 adapted to the slide bar 11 is also provided on the fastener 2. The fastener 2 can slide along the length direction of the slide bar 11, and a mounting hole 22 connected to the slide bar 11 is provided on the fastener 2. The external bolt is tightened through the mounting hole 22 and abuts against the slide bar 11 to fix the fastener 2 on the slide bar 11.

[0042] The fastener 2 is pressed against the sink 1, and abutments 21 are provided on both sides of the fastener 2. External fixing parts such as self-tapping screws can fix the fastener 2 on the installation surface (such as the top surface of the roof) through the abutments 21, that is, the sink 1 is fixed to the external installation surface through the fastener 2.

[0043] The two abutting feet 21 abut against two sides of the water tank 1 , and the fastener 2 cooperates with the abutting feet 21 on both sides to surround and fix the water tank 1 to improve the stability of the water tank 1 and prevent the water tank 1 from being deformed.

[0044] Furthermore, since the fastener 2 and the support plate 3 can be fixed to the slide bar 11 of the sink 1 by external bolts, there is no need to drill holes on the sink 1 to install and fix the fastener 2 and the support plate 3, thereby avoiding problems such as water leakage of the sink 1 due to drilling, and improving the waterproof effect of the fixing bracket.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
