Description

Technical Field

[0001] This utility model relates to the field of solar photovoltaic module installation technology, and in particular to a horizontally arranged pressure block for photovoltaic modules. Background Technology

[0002] In the construction of solar photovoltaic power plants, the installation and fixing structure of photovoltaic modules directly affects the stability and reliability of the power generation system. Currently, traditional photovoltaic module clamps generally adopt a single plate structure or a simple bolt connection method, which exposes the following technical problems in practical applications: 1. Traditional horizontal installation of photovoltaic modules relies on a complex multi-bolt fixing system. Installing a single module requires multiple steps and is time-consuming. The construction process requires multiple people working together, and there are safety hazards in special working environments such as high-altitude operations, with a high risk of bolts and tools falling. This intensive work mode increases labor costs and limits the improvement of construction efficiency. 2. Traditional pressure blocks generally adopt a rigid structure design, which has obvious shortcomings: the thicker edges of the pressure block will cast shadows on the photovoltaic panel under certain lighting angles; the lack of a precise guiding structure leads to large module installation errors, which can easily cause problems such as hot spot effect; the stress distribution at the contact surface between the pressure block and the module is uneven, exceeding the safe bearing range of the photovoltaic glass cover, resulting in a high risk of glass microcracks. 3. In traditional installation processes, each photovoltaic module requires numerous bolts and other connectors, which not only increases material costs but also necessitates the use of specialized tools, raising the investment in construction equipment. Furthermore, the installation precision of these connectors is difficult to guarantee during manual operation, potentially leading to problems such as insecure module fixation or over-tightening, thus affecting installation quality and reliability. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide an integrated photovoltaic module horizontal arrangement pressure block to solve the problems of low installation efficiency, insufficient module protection, and poor locking reliability in the prior art.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A horizontally arranged clamping block for photovoltaic modules includes a center plate, a pressure plate, and a locking block. The photovoltaic modules are laid on both sides of a T-beam. The center plate and the pressure plate are spliced ​​together and installed on the upper surface of the photovoltaic modules. The lower end of the center plate is threadedly connected to the locking block. The center plate, the pressure plate, and the locking block together clamp and fix the photovoltaic modules and the T-beam.

[0005] In a preferred embodiment, a T-shaped slot is provided on the side of the center plate, and a T-shaped guide rail is provided at the end of the pressure plate. The pressure plate is inserted into the slot through the guide rail.

[0006] In a preferred embodiment, a flange is provided at the lower end face of the pressure plate, and the position of the flange coincides with the axis of the pressure plate.

[0007] In the preferred embodiment, a flexible gasket is attached to the lower end face of the center plate.

[0008] In a preferred embodiment, a conical platform is provided at the center of the end face of the center plate, the lower end face of the conical platform is perpendicularly connected to the screw, and the conical platform and the screw are coaxial.

[0009] In the preferred embodiment, the T-beam has a mounting hole, and the screw passes through the mounting hole and is threadedly connected to the locking block.

[0010] In a preferred embodiment, the locking block includes a top plate and a knob, with the lower end face of the top plate fixedly connected to the upper end face of the knob; the top plate and the knob are coaxially arranged, and a threaded hole is provided through the axis; the top plate and the knob are threadedly connected to the screw through the threaded hole.

[0011] In a preferred embodiment, a shallow groove is provided at the upper end face of the top plate, and a spring washer is fixedly installed in the shallow groove.

[0012] In a preferred embodiment, a pressure sensor is provided at the contact surface between the pressure plate and the photovoltaic module.

[0013] In the preferred embodiment, the pressure plate has inclined chamfers on both sides.

[0014] A horizontally arranged clamping block for photovoltaic modules, the device having the following beneficial effects: 1. The pressure block adopts a modular plug-in structure design, simplifying the complex process of traditional multi-bolt fixing into a three-step operation of "positioning-plugging-locking". The flat main structure, combined with the chamfered upper edge design, reduces operational interference during installation and enables precise alignment through automated equipment, reducing the installation time of a single component by about one-third compared to traditional methods. The tapered guide structure at the root of the stud and the positioning protrusion under the pressure block form a combined guiding system, which can quickly complete the position calibration of the photovoltaic panel and the T-beam, avoiding the waste of time caused by repeated adjustments; 2. The unique cross-shaped clamping block layout design changes the traditional installation model that requires multiple people to work together, allowing a single person to complete the entire process from component positioning to fixing. This structure reduces reliance on auxiliary personnel, especially when working at heights or in complex terrain. At the same time, the number of fixing connectors for a single component is significantly reduced from the traditional 4 sets of bolts to less than 1 set on average. Combined with the tool-free plug-in structure, it reduces the investment in power tools and other equipment, resulting in a significant decrease in the overall cost of installing a single component. 3. The flexible gasket attached to the lower end face of the clamping block and the inclined chamfers on both sides of the clamping plate form a combined protective structure, which can buffer local stress during clamping and prevent scratch damage to the edges of the photovoltaic panel during installation. The coaxial design of the conical platform and the screw ensures uniform distribution of locking force. Finite element analysis has verified that this structure can control the compressive stress on the module surface within a safe threshold, significantly reducing the risk of microcracks in the glass. The pressure sensor enables real-time monitoring of the clamping force, avoiding reliability issues caused by excessive tightness or looseness. 4. The ultra-thin, flat design of the clamping block minimizes shading of the photovoltaic panels, maintaining high power generation efficiency even under low light angles. The guide ramp and automated docking structure facilitate easier maintenance of the modules and reduce the impact of maintenance work on the power generation system. The overall structure is simple and compact, with no easily damaged moving parts, significantly reducing long-term operation and maintenance costs. Attached Figure Description

[0022] Preferred solutions include Figure 5 As shown, the T-beam 1 has a mounting hole 101, and the screw 204 passes through the mounting hole 101 and is threadedly connected to the locking block 4. The locking block 4 includes a top plate 401 and a knob 403. The lower end face of the top plate 401 is fixedly connected to the upper end face of the knob 403. The top plate 401 and the knob 403 are coaxially arranged, and a threaded hole 402 is provided at the axis.

[0023] Preferred solutions include Figure 5 As shown, a shallow groove 404 is provided on the upper end face of the top plate 401. A spring washer 405 is fixedly installed in the shallow groove 404 to compensate for bolt deformation caused by temperature changes and maintain stable clamping force.

[0024] Preferred solutions include Figure 1 As shown, a pressure sensor is provided at the contact surface between the pressure plate 3 and the photovoltaic module 5, which can monitor the clamping force in real time and avoid damage to the module due to excessive pressure.

[0025] Preferred solutions include Figure 3 As shown, the pressure plate 3 adopts a flat structure design, and the inclined chamfers 303 on both sides form a smooth transition with the flat upper edge, which can reduce the shadow occlusion rate under low light angle to less than 1%. At the same time, the guide slope of the inclined chamfer 303 and the flat surface are adapted to the gripping and positioning of the automated robotic arm, which facilitates automated operations such as cleaning and inspection of the photovoltaic panel surface.
