[0033] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0034] A mounting device for photovoltaic modules, comprising:

[0035] Medium pressure block 1 is located between two adjacent photovoltaic modules and is used to simultaneously press down on the two photovoltaic modules;

[0036] Side pressure block 3, which, along with the middle pressure block 1, is located on both sides opposite the photovoltaic module and is used to press the photovoltaic module;

[0037] The fixing component 2 is used to connect to the middle pressure block 1 and the side pressure block 3 respectively. The fixing component 2 includes a pressure block connector 21 for abutting against the bottom surface of the metal bracket, a fastener 22, and a locking component 23.

[0038] The fastener 22 is used to pass through the pressure block connector 21 and the middle pressure block 1 or the side pressure block 3 and then connect to the locking member 23 to lock the photovoltaic module on the top surface of the metal bracket.

[0039] The utility model provides a fixing device for photovoltaic modules. The middle pressing block is used to press and fix two photovoltaic modules simultaneously, and then combined with the side pressing block to form pressing and fixing on the opposite sides of the photovoltaic module, which is applicable to the installation scenario of continuous laying of multiple groups of photovoltaic modules.

[0040] Further, as a preferred implementation manner of this solution rather than a limitation, the middle pressing block 1 includes a flat plate portion 11, and a left limiting portion 12 and a right limiting portion 13 that are convexly provided below the flat plate portion 11 and arranged at intervals. The flat plate portion 11 includes an intermediate portion 111 located between the left limiting portion 12 and the right limiting portion 13, a left wing portion 112 located on the left side of the left limiting portion 12, and a right wing portion 113 located on the right side of the right limiting portion 13; the left wing portion 112 and the right wing portion 113 are respectively used to press on two photovoltaic modules, and the left limiting portion 12 and the right limiting portion 13 respectively abut against the opposite side surfaces of the two photovoltaic modules, so that the two photovoltaic modules are kept at an interval;

[0041] Two first connection holes 114 for fasteners to pass through are provided on the intermediate portion 111;

[0042] In the technical solutions of existing photovoltaic power stations for the installation of photovoltaic modules, the fixing form of bolts + aluminum alloy pressing blocks is usually adopted. Generally, the shape of the aluminum alloy pressing block used resembles a "J" shape. However, due to its structural problems, the reliability of such pressing blocks is lacking. Especially in areas with high wind pressure and frequent typhoons, there are many cases of pressing block damage, seriously affecting the system safety. The middle pressing block has made innovations in mechanical design. The left limiting portion and the right limiting portion are convexly provided below the flat plate portion and arranged at intervals, forming a "π" - shaped structure. The first connection hole is located on the intermediate portion. When the fastener passes through the first connection hole, the force is transmitted from the intermediate portion to the left wing portion and the right wing portion during force application, and finally acts on the photovoltaic module. Since the left wing portion, the right wing portion and the intermediate portion are on the same flat plate portion, there is no bending position during the force transmission process, greatly optimizing the bending and deformation problems of the "J" - shaped structure during construction and high wind pressure. At the same time, the left limiting portion and the right limiting portion play the role of reinforcing ribs below the flat plate portion, improving the bending resistance of the flat plate portion.

[0043] Further, as a preferred implementation manner of this solution rather than a limitation, the thickness of the flat plate portion 11 is greater than or equal to 4 mm.

[0044] Further, as a preferred implementation manner of this solution rather than a limitation, anti - slip strips 14 are convexly provided on the bottom surfaces of the left wing portion 112 and the right wing portion 113. The plurality of anti - slip strips 14 extend in the front - rear direction of the flat plate portion 11 and are arranged at intervals in the left - right direction. The anti - slip strips are used to increase the friction force.

[0045] Furthermore, as a preferred embodiment of this solution and not a limitation, a transition arc 15 is provided at the connection position between the left limiting part 12 or the right limiting part 13 and the flat plate part 11. This is beneficial for strengthening the connection strength at the bending position.

[0046] Furthermore, as a preferred embodiment of this solution and not a limitation, the two first connecting holes 114 are spaced apart along the front-back direction of the middle portion 111.

[0047] Furthermore, as a preferred embodiment of this solution and not a limitation, the fastener 22 connects the pressure block connector 21 and the middle pressure block 1 on both the front and rear sides of the metal bracket. This helps to increase the connection strength.

[0048] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the edge pressing block 3 is disposed between two adjacent photovoltaic modules and is used to simultaneously press down on the two photovoltaic modules.

[0049] The edge pressing block 3 includes a main board portion 31, an inner limiting portion 32 protruding below the main board portion 31, and a right support portion 33 located on the right side of the main board portion 31. The main board portion 31 includes a main body portion 311 located between the inner limiting portion 32 and the right support portion 33, and a left support portion 312 located to the left of the inner limiting portion 32. The left support portion 312 is used to press against the photovoltaic module, and the inner limiting portion 32 is used to press against the side of the photovoltaic module to limit its movement. The right support portion 33 extends downward from the main board portion 31 to support a metal bracket.

[0050] The main body 311 is provided with two third connecting holes 314 for fasteners to pass through;

[0051] The main board part 31, the inner limiting part 32, and the right support part 33 are integrally formed. In the technical solutions of existing photovoltaic power stations for the installation of photovoltaic modules, the fixed form of bolts + aluminum alloy pressing blocks is usually adopted. Since photovoltaic modules generally adopt a structure of a frame plus a photovoltaic panel, the aluminum alloy pressing blocks used for the frame generally have a stepped shape. The upper step is pressed on the frame, the lower step abuts against the metal bracket, and bolts are set on the middle step for locking. However, due to the structural problems of such pressing blocks, their reliability is lacking. Especially in areas with high wind pressure and frequent typhoons, there are many cases of pressing block damage, seriously affecting the system safety. The side pressing block has been innovated in mechanical design. The left support part and the right support part protrude below the main board part and are arranged at intervals, so that a semi-“π”-shaped structure is formed on the left side of the main board part, and a semi-“J”-shaped structure is formed on the right side. The third connection hole is located on the main body part, and the fastener passes through the first connection hole. When stressed, it is transmitted from the main body part to the left support part and the right support part, and finally acts on the photovoltaic module and the metal bracket. Since the forces received by the left support part and the right support part are both downward, there is no bending position during the force transmission process, greatly optimizing the force-bearing situation where the left side of the stepped structure is under pressure and the right side is under tension, and optimizing the bending and deformation problems that occur during construction and high wind pressure.

[0052] Further, as a preferred implementation manner of this solution rather than a limitation, the thickness of the main board part 31 is greater than or equal to 4 mm.

[0053] Further, as a preferred implementation manner of this solution rather than a limitation, anti-slip teeth 34 protrude from the bottom surfaces of the left support part 312 and the right support part 33. The plurality of anti-slip teeth 34 extend in the front-back direction of the main board part 31 and are arranged at intervals in the left-right direction. The anti-slip teeth are used to increase the friction force.

[0054] Further, as a preferred implementation manner of this solution rather than a limitation, an outer limiting part 313 protruding downward is provided at the edge of the left support part 312. The protruding length of the outer limiting part 313 is less than the protruding length of the inner limiting part 32. The outer limiting part is used to directly abut against the photovoltaic module. The protrusion of the outer limiting part can adapt to the arc-shaped frame of the photovoltaic module.

[0055] Further, as a preferred implementation manner of this solution rather than a limitation, the right support part 33 is in an L shape, its upper end is connected to the right side of the main body part 311, and its lower end is used to abut against the metal bracket.

[0056] Further, as a preferred implementation manner of this solution rather than a limitation, the two third connection holes 314 are arranged at intervals in the front-back direction of the main body part 311.

[0057] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the fastener 22 is a U-bolt, the locking member 23 is a nut, and the two ends of the fastener 22 pass through the two first connecting holes 114 and are threadedly connected to the locking member 23.

[0058] Furthermore, as a preferred embodiment of this solution and not a limitation, the pressure block connector 21 is U-shaped with its opening facing downwards towards the metal bracket. The pressure block connector 21 has two spaced-apart second connecting holes 211 through which the fastener 22 passes. Using U-bolt clamps for fixing, compared to existing single-bolt fixing, makes the photovoltaic module more secure and reliable.

[0059] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the fastener 22 includes a transverse portion 221 and straight portions 222 disposed at both ends of the transverse portion 221 and perpendicular to each other. The transverse portion 221 is arc-shaped and recessed towards the opening between the two straight portions 222. When tightening, pressure is applied to the central pressure block using the transverse portion, while the elasticity of the transverse portion itself can prevent over-tightening and damage to the photovoltaic module.

[0060] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the left limiting portion 12 and the right limiting portion 13 extend along the front-rear direction of the flat plate portion 11.

[0061] The above description is only a preferred embodiment of this application and is not intended to limit the scope of implementation of this application. Any other embodiments whose principles and basic structures are the same as or similar to those of this application are within the protection scope of this application.
