[0035] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0036] First see Figure 1 , Figure 1FIG. 1 is a schematic diagram of the structure of the fixing device for photovoltaic panels of the utility model. Figure 1 As shown, the fixing device for photovoltaic panels includes two transverse connecting plates 2 arranged at intervals. Each transverse connecting plate 2 is arranged in a strip shape. Two first fixing parts are arranged at both ends of each transverse connecting plate 2, and a second fixing part is arranged in the middle of the transverse connecting plate 2. In the installed state, the two first fixing parts on the left side and the left side of the two second fixing parts fix one photovoltaic panel 11, and the right side of the two second fixing parts and the two second fixing parts on the right side fix another photovoltaic panel 11.

[0037] It should be noted that although Figure 1 Two transverse connecting plates 2 are used as an example, but this is not the only example, and at least two transverse connecting plates 2 can be provided according to the length of the photovoltaic panel 11. Those skilled in the art can make adjustments according to actual conditions.

[0038] Furthermore, in order to fix the parallel position relationship and spacing distance of the two horizontal connecting plates 2, at least two vertical connecting plates 1 perpendicular to the setting direction of the horizontal connecting plates 2 can be fixedly connected below the horizontal connecting plates 2.

[0039] See next Figure 2 and Figure 3 , Figure 2 It is a structural schematic diagram of the first fixing part of the utility model; Figure 3 FIG. 1 is an exploded schematic diagram of the first fixing portion of the present invention. Figure 2 and Figure 3 As shown, the first fixing portion may include a first clamping plate 5 and a fixing screw 301. The first clamping plate 5 may be slidably connected to the transverse connecting plate 2. The fixing screw 301 may pass through the first clamping plate 5 and engage with the transverse connecting plate 2, thereby locking the first clamping plate 5. In this way, the position of the first clamping plate 5 can be adjusted and fixed.

[0040] like Figure 2 As shown, a first slide groove 201 is provided along the length direction of the transverse connecting plate 2. The first slide groove 201 may be inverted T-shaped, wedge-shaped, etc. A placement plate 4 and a first sliding block 3 may be arranged in sequence at the bottom of the first clamping plate 5. The bottom of the first sliding block 3 is slidably connected to the first slide groove 201. A through hole 401 is provided on the placement plate 4, and the fixing screw 301 passes through the through hole 401 and is connected to the first sliding block 3, so that the placement plate 4 is fixedly connected to the first sliding block 3. When the fixing screw 301 passes through the first sliding block 3 and engages with the first slide groove 201, the first fixing portion is in a locked state.

[0041] It should be noted that although the above text and the accompanying drawings are illustrated by taking one fixed screw 301 as an example, this is not the only example. The number of the fixed screw 301 is at least one, and when there are multiple fixed screws 301, relative rotation between the placement plate 4 and the first sliding block 3 can also be avoided.

[0042] The first clamping plate 5 is fixedly connected to the side of the placement plate 4 facing the second fixing portion. The first clamping plate 5 can be arranged in an L-shape, and the first clamping plate 5 protrudes in the direction of the second fixing portion. When the photovoltaic panel 11 is installed, the contact surface of the first clamping plate 5 is engaged with the photovoltaic panel 11. Furthermore, a plurality of rubber strips 501 can be arranged on the contact surface of the first clamping plate 5, thereby playing a buffering role and avoiding damage to the photovoltaic panel 11.

[0043] See next Figures 4 to 7 , Figure 4 It is an exploded schematic diagram of the second fixing part of the utility model; Figure 5 is a cross-sectional view of the second fixing portion of the utility model; Figure 6 It is a structural schematic diagram of the guide block 8 of the utility model; Figure 7 for Figure 5 The enlarged view of A in the figure. Figures 4 to 7 As shown, the second fixing portion may include two symmetrically arranged second clamping plates 7 and a wedge-shaped extrusion block 9. The two second clamping plates 7 may be slidably connected to the first slide groove 201. The extrusion block 9 is located between the two second clamping plates 7, and the two second clamping plates 7 can be forced to slide outward by moving the extrusion block 9 downward. In this way, the distance between the first clamping plate 5 and the second clamping plate 7 can be changed, so that the first clamping plate 5 and the second clamping plate 7 are tightly engaged with both sides of the photovoltaic panel 11, thereby improving the stability of the photovoltaic panel 11.

[0044] Specifically, the second fixing part may also include a fixing frame 6 and two guide blocks 8. The two second clamps 7, the extrusion block 9 and the two guide blocks 8 are all arranged in the fixing frame 6. The contact surfaces of the two second clamps 7 and the photovoltaic panel 11 are arranged to face outward. The bottom of the fixing frame 6 can be slidably connected to the first slide groove 201. The two guide blocks 8 are connected to the opposite sides of the contact surfaces of the two second clamps 7 in a one-to-one correspondence. Each guide block 8 can be slidably connected to the inner wall of the bottom of the fixing frame 6. Furthermore, the guide block 8 can be provided with an inclined surface, and the inclined surfaces on both sides of the extrusion block 9 are engaged with the inclined surfaces of the two guide blocks 8. In this way, when the extrusion block 9 moves downward, the two second clamps 7 can be forced to slide to both sides.

[0045] The second clamping plate 7 may also be arranged in an L-shape, with the two second clamping plates 7 protruding toward the two first fixing portions, respectively. When the photovoltaic panel 11 is installed, the contact surface of the second clamping plate 7 is engaged with the photovoltaic panel 11. Furthermore, a plurality of rubber strips may be arranged on the contact surface of the second clamping plate 7 to play a buffering role and avoid damage to the photovoltaic panel 11.

[0046] The extrusion block 9 can be driven to move by setting an adjusting screw 10. Specifically, the adjusting screw 10 can be threadedly connected to the top of the fixed frame 6, and the bottom of the adjusting screw 10 is fixedly connected to the block 1001. In the assembled state, the block 1001 is engaged with the extrusion block 9. The block 1001 can be driven to move the extrusion block 9 by rotating the adjusting screw 10. Further, a card slot 901 can be set at the top of the extrusion block 9, and the card slot 901 is used to cooperate with the block 1001 so that the adjusting screw 10 is firmly connected to the extrusion block 9. Further, in order to avoid the extrusion block 9 from rotating during the rotation of the adjusting screw 10, two limit rods 902 can be set. The limit rod 902 is connected to the extrusion block 9 through a circular hole opened at the top of the fixed frame 6.

[0047] It should be noted that the above-mentioned limiting rod 902 can be one or more, and those skilled in the art can choose according to actual conditions.

[0048] Next, the guide block 8 and the fixed frame 6 are slidably connected to each other. A second sliding block 801 may be provided at the bottom of the guide block 8, and a second sliding groove 602 may be provided on the inner wall of the bottom of the fixed frame 6. The second sliding block 801 may be slidably connected to the second sliding groove 602, so that the second sliding frame may drive the guide block 8 and the second clamping plate 7 to slide.

[0049] A third sliding block 601 may be fixedly arranged at the bottom of the fixing frame 6. A third sliding block 601 may be arranged at the bottom of the third sliding block 601, and the third sliding block 601 may be slidably connected to the first sliding groove 201.

[0050] In actual work, when installing the photovoltaic panel 11, the worker first clamps the first sliding block 3 in the first sliding groove 201, and then places the placement plate 4 connected with the first clamping plate 5 on the upper part of the first sliding block 3. The fixing screw 301 is connected to the through hole 401, and the first clamping plate 5 can fix one side of the photovoltaic panel 11.

[0051] Next, the third sliding block 601 is clamped in the first slide groove 201, and the adjusting screw 10 is threadedly connected to the top plate of the fixed frame 6. The second sliding block 801 is slidably clamped in the second slide groove 602, and by rotating the adjusting screw 10, the extrusion block 9 can be driven to move downward, thereby pushing the two guide blocks 8 and the second clamping plate 7 outward. In this way, the second clamping plate 7 can fix one side of the inner end of the photovoltaic panel 11, and after the extrusion block 9 moves downward, the two second clamping plates 7 can be tightly fitted to one side of the inner ends of the two adjacent photovoltaic panels 11, thereby improving the stability of the photovoltaic panel 11 on the surface of the horizontal connecting plate 2.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
