[0004] In other words, existing technologies have the following technical problems: ordinary photovoltaic panel clamping blocks are prone to damage due to excessive clamping force during compression. Therefore, a single-sided photovoltaic panel clamping block assembly is proposed to address the above problems. Utility Model Content

[0032] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0033] Please see Figure 1-6 As shown, a single-sided photovoltaic panel clamping assembly includes:

[0034] A clamping assembly 1, wherein a manual control structure 2 is fixedly provided at the bottom end of the clamping assembly 1;

[0035] The clamping assembly 1 includes a first limiting pressure plate 102 and a second limiting pressure plate 103, and the manual control structure 2 is used to adjust the distance between the first limiting pressure plate 102 and the second limiting pressure plate 103.

[0036] Pressure control unit 4 is disposed at the second limiting pressure plate 103, and the pressure control unit 4 is used to control the clamping force during clamping;

[0037] Through the above technical solution, the pressure control unit 4 and the manual control structure 2 work together to indicate the pressure while pressing, thereby avoiding damage to the photovoltaic panel 6 caused by excessive pressing force. It is also simple and convenient to operate, quick to use, and suitable for large-scale use to press and fix the photovoltaic panel 6.

[0038] The first limiting pressure plate 102 is provided with a sliding groove, and a rectangular guide rod 101 is slidably connected to the sliding groove of the first limiting pressure plate 102;

[0039] The pressure control unit 4 includes a movable sleeve 401, a control spring 402, and an indicator rod 403. The movable sleeve 401 is disposed in the inner cavity of the rectangular guide rod 101 and slides with the rectangular guide rod 101. One end of the control spring 402 is fixedly connected to the bottom end of the movable sleeve 401, and the other end of the control spring 402 is fixedly connected to the bottom wall of the inner cavity of the rectangular guide rod 101.

[0040] The upper end of the movable sleeve 401 is fixedly connected to the bottom surface of the second limiting pressure plate 103. An indicator rod 403 is slidably connected within the inner cavity of the movable sleeve 401. The bottom end of the indicator rod 403 is fixedly connected to the bottom wall of the inner cavity of the rectangular guide rod 101. The indicator rod 403 passes through the second limiting pressure plate 103 and slides with it. Through this technical solution, when the photovoltaic panel 6 is pressed by the first limiting pressure plate 102 and the second limiting pressure plate 103, the first limiting pressure plate 102 is positioned on the bottom side of the photovoltaic panel, and the second limiting pressure plate 103 is positioned on the top side of the photovoltaic panel. The rectangular guide rod 101 is then manually controlled by the structure 2. The guide rod 101 moves downward, thereby driving the second limiting pressure plate 103 to press down, thus achieving the function of clamping and fixing. When the second limiting pressure plate 103 is pressed down, the pressure can be controlled by the control spring 402. The longer the control spring 402 is stretched, the greater the pressure of the second limiting pressure plate 103. At this time, the indicator rod 403 moves downward relative to the second limiting pressure plate 103. By observing the relative position of the through indicator rod 403 on the second limiting pressure plate 103, the stretching length of the control spring 402 can be determined, thereby determining the magnitude of the pressure and avoiding damage caused by excessive pressure.

[0041] Preferably, the top of the indicator rod 403 is provided with a scale mark; the surface of the second limiting pressure plate 103 is provided with an observation window or marking line corresponding to the indicator rod 403, which is used to intuitively reflect the extension and contraction of the control spring 402 by the displacement distance of the top of the indicator rod 403; when the top of the indicator rod 403 is aligned with the reference line on the surface of the second limiting pressure plate 103, it indicates that the preset safe clamping force has been reached; if the top of the indicator rod 403 is lower than the reference line and exceeds the set threshold, it indicates that the clamping force is overloaded.

[0042] A locking bolt 5 is threaded onto the side wall of the rectangular guide rod 101. With this technical solution, once the applied pressure is determined, the locking bolt 5 can be directly tightened to press against the side wall of the movable sleeve rod 401, thus locking and fixing the rectangular guide rod 101 and the movable sleeve rod 401. The locking bolt 5 passes through a threaded hole in the side wall of the rectangular guide rod 101, and its end abuts against the outer side wall of the movable sleeve rod 401. When the locking bolt 5 is tightened, its end presses against the outer wall of the movable sleeve rod 401, achieving axial fixation of the rectangular guide rod 101 and the movable sleeve rod 401 through friction, thereby locking the pressing position of the second limiting pressure plate 103.

[0043] The manual control structure 2 includes a fixed guide plate 201, a fixed bracket 202, an eccentric wheel 204, and an adjusting handle 205. The fixed guide plate 201 is fixedly installed at the bottom end of the rectangular guide rod 101, and the fixed bracket 202 is fixedly installed at the bottom surface of the first limiting pressure plate 102.

[0044] The bottom of the fixed bracket 202 is rotatably connected to a fixed shaft 203. An eccentric wheel 204 is fixedly connected to the arc-shaped wall of the fixed shaft 203. An adjusting handle 205 is fixedly connected to one end of the fixed shaft 203. With this technical solution, when it is necessary to press down, the operator can manually turn the adjusting handle 205 to drive the fixed shaft 203 to rotate. The rotation of the fixed shaft 203 can drive the eccentric wheel 204 to rotate. Due to the eccentric setting of the eccentric wheel 204, as the eccentric wheel 204 rotates, it can gradually squeeze the fixed guide plate 201, causing the fixed guide plate 201 to move down. The fixed guide plate 201 drives the rectangular guide rod 101 to move down, thereby driving the second limiting pressure plate 103 to achieve the pressing action. By setting the adjusting handle 205, the pressing operation can be made simpler, and due to the lever principle, it can save more effort.

[0045] Preferably, the maximum radius side of the eccentric wheel 204 is tangent to the bottom surface of the fixed guide plate 201; when the adjustment handle 205 is rotated, the protrusion of the eccentric wheel 204 gradually pushes the fixed guide plate 201, and the lever amplification effect is converted into the downward pressure of the rectangular guide rod 101. The bottom of the fixed guide plate 201 is provided with a wear-resistant pad to reduce the rotational friction of the eccentric wheel 204.

[0046] The first limiting pressure plate 102 is provided with a self-locking unit 3, which includes a limiting slider 301, a limiting spring 303, and a latch 304. The first limiting pressure plate 102 has an inner cavity. The limiting slider 301 is slidably connected in the inner cavity of the first limiting pressure plate 102. One end of a handle rod 302 is fixedly connected to one side wall of the limiting slider 301. The other end of the handle rod 302 passes through the inner cavity wall of the first limiting pressure plate 102 and extends to the outside of the wall. One end of a limiting spring 303 is fixedly connected to the side wall of the limiting slider 301. The other end of the limiting spring 303 is fixedly connected to the side wall of the first limiting pressure plate 102.

[0047] A latch 304 is fixedly connected to one side of the limiting slider 301. One end of the latch 304 extends to the side wall of the rectangular guide rod 101. The side wall of the rectangular guide rod 101 is provided with a groove. One end of the latch 304 extends into the groove of the rectangular guide rod 101. Several slots 305 are fixedly provided in the groove of the rectangular guide rod 101. Both the slots 305 and the latch 304 have bevels at one end. Through this technical solution, when the rectangular guide rod 101 moves downward, the slots 305 can move downward to press the latch 304. This causes the latch 304 to be compressed and retracted. After retraction, the slot 305 continues to move downward. The latch 304 inserts into the gap of the slot 305, which can limit the slot 305. This, in turn, provides a self-locking limit for the rectangular guide rod 101. Under normal use, the rectangular guide rod 101 can only move downward in one direction and cannot move in the opposite direction. When it is necessary to move in the opposite direction, the handle rod 302 can be pulled manually, which will drive the limit slider 301 to move, causing the latch 304 to move and separate from the slot 305, thus achieving the unlocking function.

[0048] Preferably, a plurality of slots 305 are evenly distributed along the axial direction in the groove of the side wall of the rectangular guide rod 101, and the spacing between adjacent slots 305 is less than the displacement allowed by the thickness tolerance of the photovoltaic panel 6.

[0049] The inclined angle of the latch 304 matches the inclined surface of the slot 305, so that when the rectangular guide rod 101 moves down, the latch 304 is compressed by the inclined surface, compressing the limiting spring 303 and automatically sliding into the next slot 305. When unlocking is required, pulling the handle rod 302 outward causes the limiting slider 301 to overcome the elastic force of the limiting spring 303, causing the latch 304 to disengage from the slot 305.

[0050] The control spring 402 of the pressure control unit 4 only serves as a buffer and pressure indicator during the pressing process; when the pressing is completed, the movable sleeve 401 is rigidly connected to the rectangular guide rod 101 by the mechanical locking of the locking bolt 5, and the displacement of both ends of the spring 402 is forcibly locked, so that the vibration energy cannot trigger the spring oscillation.

[0051] Meanwhile, the latch 304 of the self-locking unit 3 continuously engages with the slot 305 of the rectangular guide rod 101 under the action of the limiting spring 303, resisting the micro-displacement caused by wind vibration, and the double locking ensures that the clamping assembly has no rebound.

[0052] When using the compressed photovoltaic panel 6:

[0053] 1. First, place the first limiting plate 102 at the bottom edge of the photovoltaic panel 6, and suspend the second limiting plate 103 at the top of the photovoltaic panel 6;

[0054] 2. Rotating the adjustment handle 205 drives the eccentric wheel 204 to press down the fixed guide plate 201, which in turn drives the rectangular guide rod 101 and the second limit pressure plate 103 to move down and press the photovoltaic panel.

[0055] 3. Simultaneously observe the relative position of the top of the indicator rod 403 and the second limiting pressure plate 103 until the preset clamping force is reached;

[0056] 4. Tighten the locking bolts 5 to fix the position;

[0057] 5. When unloading, first loosen the locking bolt 5, then pull the handle rod 302 to release the self-locking unit 3, and rotate the adjusting handle 205 in the opposite direction to raise the second limit pressure plate 103 to achieve loosening and disassembly.

[0058] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
