In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0042] Combine the following Figure 1-Figure 7 The technical solution of the present invention is further illustrated through specific implementation methods.

[0043] When using solar photovoltaic modules, in order to improve the firmness of photovoltaic panel installation, the present invention provides a fixing device, which includes a support member 1 and a clamping mechanism 2. The support member 1 is provided with a receiving groove 11 and a gas channel that are interconnected; the clamping mechanism 2 includes an extrusion component 21 and a clamping member 22, the extrusion component 21 and the clamping member 22 are respectively located at the two ends of the gas channel and can close the gas channel, a part of the extrusion component 21 is located in the receiving groove 11 for placing the photovoltaic panel, and the other part is movably arranged at one end of the gas channel, and the extrusion component 21 can move along the direction of the groove depth of the receiving groove 11, and the clamping member 22 can be telescopically arranged at the other end of the gas channel so that the clamping member 22 abuts against or is away from the upper surface of the photovoltaic panel.

[0044] Specifically, when the fixing device is not installed with a photovoltaic panel, the extrusion assembly 21 and the clamping member 22 maintain static balance under the action of compressed air. During installation, the photovoltaic panel is placed on the extrusion assembly 21, and a force is applied to the photovoltaic panel along the depth direction of the receiving groove 11. The extrusion assembly 21 slides toward the bottom of the receiving groove 11, so that the compressed air is squeezed from one side of the extrusion assembly 21 to one side of the clamping member 22 along the gas channel. As the compressed air continues to flow in, the clamping member 22 is pushed to slide in the direction close to the receiving groove 11 and abuts against the upper surface of the photovoltaic panel, thereby fixing the photovoltaic panel. During disassembly, the clamping member 22 is pushed, and the compressed air is squeezed from one side of the clamping member 22 to one side of the extrusion assembly 21 along the gas channel. The clamping member 22 slides in the direction away from the receiving groove 11, thereby releasing the fixation of the photovoltaic panel. The extrusion assembly 21 is reset under the action of compressed air, and the photovoltaic panel can be removed from the extrusion assembly 21. The device achieves the clamping and fixing of the photovoltaic panel by squeezing compressed air to push the clamping member 22 to slide, so that the installation is firm and reliable, the operation process is simple, and the installation efficiency is improved.

[0045] Optionally, when removing the photovoltaic panel, force can be applied manually to the clamping member 22 to make it slide away from the accommodating groove 11, or the clamping member 22 can be connected to a device such as a cylinder to control the movement of the clamping member 22, etc., which is not specifically limited here.

[0046] Alternatively, if Figure 2 As shown, a second slide groove 13 is provided at the bottom of the accommodating groove 11, a ventilation groove 14 is provided inside the support member 1, a third slide groove 15 is provided on the groove wall of the accommodating groove 11, and a clamping member 22 is provided in the groove wall of the accommodating groove 11, and the ventilation groove 14 connects the second slide groove 13 with the third slide groove 15, and the second slide groove 13, the third slide groove 15 and the ventilation groove 14 form a gas channel, the extrusion component 21 is sealed and connected to the second slide groove 13, and the clamping member 22 is sealed and connected to the third slide groove 15, and the direction of the notch of the second slide groove 13 is perpendicular to the direction of the notch of the third slide groove 15, and a sealed gas channel is formed through the second slide groove 13, the third slide groove 15 and the ventilation groove 14, the extrusion component 21 and the clamping member 22, and the photovoltaic panel is pressed, and the extrusion component 21 slides along the direction of the groove depth of the second slide groove 13, and the compressed air is squeezed to flow to the third slide groove 15 along the gas channel, thereby pushing the clamping member 22 to slide in the direction of the notch of the third slide groove 15. This arrangement can facilitate the flow of compressed air, thereby better fixing the photovoltaic panels.

[0047] Further, the extrusion assembly 21 includes a first extrusion member 211 and a second extrusion member 212. The first extrusion member 211 is disposed in the receiving groove 11 for supporting the photovoltaic panel. Further, the second extrusion member 212 includes a first connection portion 2121 and an extrusion portion 2122. One end of the first connection portion 2121 is connected to the first extrusion member 211, and the other end is connected to the extrusion portion 2122. The extrusion portion 2122 is sealed and connected to the second slide groove 13. The notch of the second slide groove 13 is provided with a first extension portion. Correspondingly, the first connection portion 2121 and the extrusion portion 2122 are arranged in a T-shape. When disassembling the photovoltaic panel, the second extrusion member 212 slides toward the notch direction of the second slide groove 13, the first connection portion 2121 extends out of the second slide groove 13, and the extrusion portion 2122 can abut against the first extension portion, effectively preventing the second extrusion member 212 from sliding out of the second slide groove 13.

[0048] The clamping member 22 includes a second connecting portion 221 and a clamping portion 222. The second connecting portion 221 is sealingly connected to the third slide groove 15. The clamping portion 222 is used to clamp onto the photovoltaic panel. A second extension portion is provided at the notch of the third slide groove 15. Correspondingly, the second connecting portion 221 and the clamping portion 222 are T-shaped. When installing the photovoltaic panel, the clamping member 22 slides toward the notch of the third slide groove 15. The clamping portion 222 can extend out of the third slide groove 15 and abut against the upper surface of the photovoltaic panel, while the second connecting portion 221 abuts against the second extension portion, which can effectively prevent the clamping member 22 from sliding out of the third slide groove 15.

[0049] Optionally, there are two gas channels, which are symmetrically arranged inside the support member 1 along the axis of the accommodating groove 11. Correspondingly, there are two second slide grooves 13, three slide grooves 15 and ventilation grooves 14. The second extrusion members 212 and the clamping members 22 are arranged in one-to-one correspondence with the gas channels. The two second extrusion members 212 are connected to the first extrusion member 211, and the two clamping members 22 are respectively abutted against the two ends of the photovoltaic panel, thereby improving the stability of the installation of the photovoltaic panel.

[0050] In order to further ensure the firmness of photovoltaic panel installation, Figure 3As shown, the fixing device also includes a locking assembly 3, which is arranged on the extrusion assembly 21, and the locking assembly 3 can keep the clamping member 22 in a state of abutting against the upper surface of the photovoltaic panel. In detail, the bottom of the accommodating groove 11 is provided with a first slide groove 12, and the groove wall of the first slide groove 12 is provided with a fixing hole 121. The locking assembly 3 includes a connecting member 31, a locking member 32 and a first elastic member 33. The connecting member 31 is fixed to the first extrusion member 211, the locking member 32 is arranged in the connecting member 31, and is slidably connected with the connecting member 31. The first elastic member 33 is arranged between the connecting member 31 and the locking member 32. Under the action of the first elastic member 33, the locking member 32 can extend from the connecting member 31 and be inserted into the fixing hole 121, or retract into the connecting member 31 and abut against the groove wall of the first slide groove 12. The locking assembly 3 also includes a third elastic member 34, the two ends of which are elastically abutted against the bottom of the first chute 12 and the connecting member 31, respectively, for supporting the connecting member 31 and the locking member 32. During installation, the photovoltaic panel is pressed, and the connecting member 31 and the locking member 32 slide toward the bottom of the first chute 12 along with the first extrusion member 211. When the photovoltaic panel is installed in place, the clamping member 22 abuts against the upper surface of the photovoltaic panel to fix it. At the same time, the locking member 32 slides to the fixing hole 121, and under the action of the first elastic member 33, it extends from the connecting member 31 and is inserted into the fixing hole 121, further fixing the photovoltaic panel in the vertical direction, thereby improving the firmness of the photovoltaic panel installation. During disassembly, the clamping member 22 and the locking member 32 are pushed at the same time, the clamping member 22 is retracted into the side wall of the accommodating groove 11, and the locking member 32 is retracted into the connecting member 31, so as to release the clamping of the photovoltaic panel, and the connecting member 31 and the locking member 32 are reset under the action of the third elastic member 34.

[0051] Optionally, one end of the locking member 32 away from the first elastic member 33 is a wedge-shaped structure, which is conducive to the locking member 32 extending out or retracting into the connecting member 31.

[0052] In order to facilitate the removal of photovoltaic panels, Figure 4 and Figure 5 As shown, the fixing device further includes an unlocking assembly 4 , which is inserted into the fixing hole 121 . The unlocking assembly 4 can drive the locking member 32 to move so that the locking member 32 leaves the fixing hole 121 .

[0053] Specifically, the unlocking assembly 4 includes an unlocking member 41, which is inserted into the fixing hole 121. The unlocking member 41 includes a pushing portion 411 and an abutting portion 412. One end of the pushing portion 411 is located outside the support member 1, and the other end is fixedly connected to one side of the abutting portion 412. The other side of the abutting portion 412 is opposite to the fixing hole 121. The pushing portion 411 can drive the abutting portion 412 to move along the extension direction of the fixing hole 121. When disassembling the photovoltaic panel, the pushing portion 411 is pushed outside the support member 1 to drive the abutting portion 412 to move in a direction close to the locking member 32, so that the abutting portion 412 contacts the locking member 32, thereby pushing the locking member 32 to leave the fixing hole 121 and unlocking the photovoltaic panel. The pushing portion 411 avoids operating the locking member 32 in the fixing hole 121, and the abutting portion 412 is provided to increase the contact area between the unlocking member 41 and the locking member 32, making disassembly more convenient.

[0054] Furthermore, the unlocking assembly 4 also includes a connecting piece 42 and a second elastic piece 43. The connecting piece 42 is inserted into the fixing hole 121. A cavity is provided in the connecting piece 42. A first through hole 421 is provided on one side wall of the cavity, and a second through hole 422 is provided on the other side wall opposite thereto. The pushing portion 411 is inserted into the first through hole 421 and is sealedly connected to the peripheral wall of the first through hole 421. One end of the pushing portion 411 is located outside the connecting piece 42, and the other end is located in the cavity. The abutting portion 412 is located in the cavity, and its two ends abut against the side wall of the cavity. The two ends of the second elastic piece 43 elastically abut against the abutting portion 412 and the side wall of the cavity where the first through hole 421 is located, respectively. When the photovoltaic panel is installed in place, the locking member 32 is inserted into the second through hole 422 to further fix the photovoltaic panel. When removing the photovoltaic panel, the pushing part 411 is pushed, and the pushing part 411 drives the abutting part 412 to move, and then the abutting part 412 contacts the locking member 32, and the locking member 32 is retracted into the connecting member 31 away from the second through hole 422 and abuts against the groove wall of the first slide groove 12. The pushing part 411 is released, and it returns to its initial state under the action of the second elastic member 43. Through a series of mechanical linkages, the photovoltaic panel is automatically clamped, fixed and disassembled, making the entire operation process simple and easy to operate, and improving the efficiency of installation and disassembly. In addition, the connection member 42 is sealed to the peripheral wall of the fixing hole 121, and the pushing part 411 is sealed to the peripheral wall of the first through hole 421, so that the interior of the entire device can always maintain a stable state.

[0055] In order to make the photovoltaic panels receive sunlight better, the installation angle of the photovoltaic panels needs to be adjusted during use, such as Figure 6As shown, in this embodiment, the fixing device also includes a fixing seat 5, and the support member 1 is rotatably arranged at one end of the fixing seat 5, and the height of the other end of the fixing seat 5 in the vertical direction can be adjusted to support the support member 1 after the angle is adjusted. Specifically, the fixing seat 5 includes a first fixing seat 51 and a second fixing seat 52, and a fixing shaft 521 is arranged on the second fixing seat 52, and the rotating shaft 522 is rotatably arranged on the fixing shaft 521. A rotating groove is arranged on the support member 1, and the rotating groove and the rotating shaft 522 are rotatably matched. One end of the support member 1 overlaps the first fixing seat 51 to support and fix the support member 1 after the angle is adjusted. When the angle needs to be adjusted, lift the end of the support member 1 overlapped with the first fixing seat 51, and rotate the support member 1 around the fixing shaft 521. After the angle is adjusted, the support member 1 is supported and fixed by the first fixing seat 51 of appropriate height.

[0056] Furthermore, the fixing device also includes an adjusting member 6, which is slidably arranged on the fixing seat 5 and is located between the first fixing seat 51 and the second fixing seat 52. The top of the adjusting member 6 contacts the bottom of the supporting member 1. When the adjusting member 6 slides between the first fixing seat 51 and the second fixing seat 52, it can drive the supporting member 1 to rotate around the fixing axis 521, so that adjustment of smaller angles is more convenient, and the adjusting member 6 can support the supporting member 1, ensuring the stability of the device.

[0057] Optionally, a connecting rod 53 is provided on the fixing seat 5, and two ends of the connecting rod 53 are respectively fixed on the first fixing seat 51 and the second fixing seat 52, and the adjusting member 6 is slidably matched with the connecting rod 53. Optionally, a third through hole 61 is provided on the adjusting member 6, and the connecting rod 53 is inserted into the third through hole 61, so that the adjusting member 6 slides along the extension direction of the connecting rod 53.

[0058] Furthermore, the adjusting member 6 is provided with a first connection hole 62, and the connecting rod 53 is provided with a plurality of second connection holes 531 at intervals along its extension direction. The fastener 7 can be inserted into the second connection hole 531 through the first connection hole 62. After the photovoltaic panel angle is adjusted, the adjusting member 6 can be fixed to the connecting rod 53 to prevent the shaking of the adjusting member 6 from affecting the use effect of the photovoltaic panel. When the angle needs to be adjusted, the fastener 7 is taken out to make the adjusting member 6 slide along the connecting rod 53.

[0059] Optionally, in this embodiment, two connecting rods 53 are provided, and the adjusting member 6 is slidably connected to the two connecting rods 53 respectively, thereby ensuring the stability of the fixing seat 5 and further ensuring the working stability of the photovoltaic panel.

[0060] A plurality of grooves 63 are provided on one side of the adjusting member 6 close to the supporting member 1, and a rolling member 8 is rotatably connected in the groove 63, and the rolling member 8 can reduce the friction between the adjusting member 6 and the supporting member 1. During the angle adjustment process, as the adjusting member 6 slides on the connecting rod 53, a relative motion is generated between the supporting member 1 and the rolling member 8, and the sliding friction is converted into rolling friction, making the angle adjustment process smoother and more labor-saving.

[0061] In order to prevent dust and other impurities from falling on the photovoltaic panels and affecting the power generation efficiency of the photovoltaic panels, such as Figure 7 As shown, the device also includes a dustproof member 9, which is covered on the top of the receiving groove 11 and can block dust and other impurities. Furthermore, the dustproof member 9 is set to be transparent, which not only can play a dustproof role, but also will not hinder the sunlight from shining on the photovoltaic panel, thereby ensuring the normal operation of the photovoltaic panel. In this embodiment, the dustproof member 9 includes a dustproof portion 91 and a fixing portion 92, the fixing portion 92 is fixed on the dustproof portion 91, and a positioning hole 16 is provided on the support member 1. The fixing portion 92 is plugged into the positioning hole 16, so that the dustproof portion 91 is supported above the support member 1. When the photovoltaic panel needs to be maintained, the fixing portion 92 is pulled out from the positioning hole 16, and the dustproof portion 91 is removed, and the operation can be carried out.
