However, the middle installation member needs to be fixed with nuts, and the construction workers need to complete the installation below the truss, which brings inconvenience to the installation.

Content of the Utility Model

[0004] Aiming at the deficiencies in the prior art, the technical problem to be solved by the utility model is to provide a middle pressing block installation structure for photovoltaic modules, which does not use traditional bolt connections, is convenient for installation, and has reliable installation.

[0005] To solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A middle pressing block installation structure for photovoltaic modules includes a middle pressing block arranged above the purlin and pressing the frame edges of two adjacent photovoltaic modules. The middle pressing block installation structure further includes a combined hoop, which includes a hoop body with an opening and a locking buckle for closing the opening. The hoop body is clamped on the purlin and passes through the middle pressing block, and after the locking buckle closes the opening, the hoop body fixes the middle pressing block.

[0007] Preferably, the middle pressing block includes a U-shaped part and side pressing edges extending from the mouth of the U-shaped part to both sides. The U-shaped part is inserted between the frame edges of two adjacent photovoltaic modules, and the two side pressing edges are correspondingly pressed on the frame edges of the two adjacent photovoltaic modules.

[0008] Preferably, the hoop body is a rectangular structure and the opening is arranged on one of its sides, and the hoop body passes through the inner side of the U-shaped part; and / or, the purlin is a square pipe purlin.

[0009] Preferably, the locking buckle includes a locking piece connected to one side of the opening and a buckle wrench connected to the locking piece, and a buckle portion is provided on the other side of the opening. The locking piece passes over the opening and the buckle wrench is buckled and fixed to the buckle portion.

[0010] Preferably, the buckling portion is a buckle groove, and the head of the buckle wrench is provided with a buckle head buckled with the buckle groove.

[0011] Preferably, the locking member is a steel ring.

[0012] Preferably, the steel ring is an inverted isosceles trapezoidal structure, and the snap-on wrench is connected to the upper bottom edge of the steel ring.

[0013] Preferably, a long hole is provided on one side of the opening, and the lower bottom edge of the steel ring is transferred into the long hole; and / or, a fulcrum part that cooperates with the upper bottom edge of the steel ring is provided in the middle part of the snap wrench.

[0014] Preferably, the clamp body is made of metal and is elastic.

[0015] Preferably, the intermediate pressure block is made of stainless steel or aluminum alloy.

[0016] The utility model adopts the above technical solution and has the following beneficial effects:

[0017] 1. Use the medium pressure block in conjunction with the combined clamp. Since the clamp body is engaged with the purlin and passes through the medium pressure block, the medium pressure block is fixed to the purlin by the clamping effect of the combined clamp. The medium pressure block then presses and fixes the frames of the photovoltaic modules on the adjacent two sides, so that the photovoltaic modules can be fixed to the purlin.

[0018] Since the locking buckle is used to close the opening and then the clamp body fixes the medium voltage block, it is easy to install and does not use traditional bolt connections; since traditional bolt connections are not used, there is no need to tighten the bolts during the installation process, which is simple to operate and quick to construct, thus speeding up the construction of the power station. The locking buckle achieves a tightening effect through self-locking of the buckle. After the locking buckle is fixed, it is not easy to separate and the installation is reliable.

[0019] 2. The middle pressure block has a U-shaped part and side pressure edges on both sides, wherein the U-shaped part is inserted between the frames of two adjacent photovoltaic modules and fixed by a combination clamp, so that the side pressure edges on both sides are pressed against the frames of the two photovoltaic modules. Therefore, the photovoltaic modules on both sides are pressed and fixed, and no shadow is caused to the photovoltaic modules. In addition, the middle pressure block does not need to contact the purlin. The middle pressure block is fixed at a position with high frame strength, which can prevent the frame of the photovoltaic module from being torn under strong winds.

[0020] 3. Since the hoop body is of a rectangular structure with an opening on one of its sides, the hoop body is initially held in place with the square tube purlin and the middle pressing block by opening the opening. The hoop body passes through the inner side of the U-shaped part, and then the locking buckle is used to close the opening, so that the hoop body fixes the middle pressing block. In this way, the hoop body presses against the bottom wall of the U-shaped part, fixes the middle pressing block to the purlin, and can cooperate with the square tube purlin, making the fixation more reliable.

[0021] 4. After the hoop body is initially held in place with the square tube purlin and the middle pressing block, turn the locking part downward. The locking part crosses the opening. At the same time, pull the buckle wrench so that the buckle wrench is fastened to the fastening part. The fastening part is a fastening groove, and the head of the buckle wrench is provided with a buckle head that fastens to the fastening groove. That is, turn the buckle wrench to fasten the buckle head to the fastening groove, thus achieving a self-locking effect and being not easily separated.

[0022] 5. The locking part is preferably a steel ring with an inverted isosceles trapezoid structure. There is a long hole on one side of the opening. The lower bottom edge of the steel ring is connected to the long hole and can move along the long hole, thus realizing the connection and relative rotation between the two. The buckle wrench is connected to the upper bottom edge of the steel ring. When the steel ring rotates downward across the fastening groove, turn the buckle wrench so that the buckle head is fastened to the fastening groove. Since the steel ring has a relatively large deformation amount, it can not only increase the reliability of locking in the locked state.

[0023] 6. Since the hoop body is made of metal, it has a certain elasticity. In this way, during the installation process, the opening is opened by means of the elasticity, and the hoop body is initially held in place on the square tube purlin and the U-shaped part of the middle pressing block, which facilitates the installation. After the buckle wrench is fastened, the elasticity enables a large fastening force between the buckle wrench and the fastening part, enhancing the reliability of the fixation.

[0024] 7. The middle pressing block is made of stainless steel or aluminum alloy profile, which not only prevents rust and extends the service life, but also has the advantage of low mass production cost.

[0025] These features and advantages of the present utility model will be disclosed in detail in the following specific embodiments and drawings.

[0031] The technical solutions of the embodiments of the present utility model will be explained and described below with reference to the accompanying drawings of the embodiments of the present utility model. However, the following embodiments are only the preferred embodiments of the present utility model, not all of them. Based on the embodiments in the implementation manners, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present utility model.

[0032] Those skilled in the art can understand that, without conflict, the features in the following embodiments and implementation manners can be combined with each other.

[0033] The terms used in the present utility model are only for the purpose of describing specific embodiments, and are not intended to limit the present utility model. For example, the terms such as "upper", "lower", "longitudinal", "lateral" and the like indicating the orientation or position relationship are only based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device / component referred to must have a specific orientation or be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the present utility model.

[0034] In the present utility model, unless otherwise clearly specified and limited, the first feature being "above" or "below" the second feature may include direct contact between the first and second features, or may include indirect contact between the first and second features through other features therebetween. Moreover, the first feature being "above", "over" and "on" the second feature includes the first feature being directly above and obliquely above the second feature, or merely indicating that the first feature has a higher horizontal height than the second feature. The first feature being "below", "under" and "beneath" the second feature includes the first feature being directly below and obliquely below the second feature, or merely indicating that the first feature has a lower horizontal height than the second feature.

[0035] In addition, the terms "first", "second", etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first", "second" may explicitly or implicitly include at least one such feature.

[0036] Referring to the prior art, a number of photovoltaic modules are distributed in a rectangular array and installed on a photovoltaic support. A plurality of photovoltaic modules are arranged side by side both horizontally and vertically. The photovoltaic modules are provided with frames, and the photovoltaic support is provided with a number of purlins. The purlins extend horizontally. A medium pressure block is provided between two adjacent photovoltaic modules on both sides. The medium pressure block is fixed to the purlin and fixes the frames of the two adjacent photovoltaic modules on both sides.

[0037] Taking the use of square tube purlins as an example, referring to Figures 1 to 3 As shown, this embodiment provides a medium pressure block installation structure for a photovoltaic module, including a medium pressure block 2 disposed above a square tube purlin 7 and pressing the frames 1 of two adjacent photovoltaic modules 100. The medium pressure block installation structure further includes a combined hoop. The combined hoop includes a hoop body 3 with an opening 31 and a locking buckle for closing the opening. The hoop body 3 is clamped around the square tube purlin 7 and passes through the medium pressure block 2. After the locking buckle closes the opening, the hoop body 3 fixes the medium pressure block 2 to the square tube purlin 7. Of course, the above medium pressure block installation structure is not limited to being installed on a square tube purlin, and can also be other common purlins, such as C-shaped purlins.

[0038] In the above technical solution, the medium pressure block is used in combination with the combined hoop. Since the hoop body is clamped around the purlin and passes through the medium pressure block, the medium pressure block is fixed to the purlin by relying on the clamping action of the combined hoop. The medium pressure block then presses and fixes the frames of the two adjacent photovoltaic modules on both sides, so that the photovoltaic modules can be fixed to the purlin. Since the locking buckle is used to close the opening and then the hoop body fixes the medium pressure block, it is convenient for installation and does not use traditional bolt connections. Since traditional bolt connections are not used, there is no need to screw bolts during the installation process, the operation is simple, the construction is rapid, and the speed of power station construction is accelerated. The locking buckle achieves a fastening effect through self-locking of the buckle. After the locking buckle is fixed, it is not easy to separate, and the installation is reliable.

[0039] As a common structure, the medium pressure block 2 includes a U-shaped portion 21 and side pressing edges 22 extending from the mouth of the U-shaped portion to both sides. The U-shaped portion 21 is inserted between the frames of two adjacent photovoltaic modules, and the two side pressing edges 22 are correspondingly pressed on the frames of the two photovoltaic modules. It not only presses and fixes the two photovoltaic modules on both sides, but also does not cause shadow occlusion to the photovoltaic modules. Moreover, the medium pressure block does not need to contact the purlin. The medium pressure block is fixed at a position with high frame strength, which can avoid the situation of frame tearing of the photovoltaic module under the action of strong wind. Preferably, the medium pressure block 2 is made of stainless steel or aluminum alloy profile. It not only prevents rust and extends the service life, but also has the advantage of low mass production cost.

[0040] Among them, the clamp body 3 is a rectangular structure and the opening is provided on one side, and the clamp body 3 passes through the inner side of the U-shaped portion 21. In this way, the clamp body presses the bottom wall of the U-shaped portion to fix the middle pressure block to the purlin. The locking buckle includes a locking piece 4 connected to one side of the opening (the upper side in the figure), and a buckle wrench 5 connected to the locking piece 4. A buckle part 6 is provided on the other side of the opening (the lower side in the figure). The locking piece passes over the opening and the buckle wrench is buckled and fixed with the buckle part. The self-locking is achieved by the buckle wrench and the clamp buckle of the semi-open clamp. After the locking buckle is fixed, it is not easy to separate, which is safe and reliable.

[0041] Preferably, the buckle portion 6 is a buckle groove, which may have an opening edge folded outward in an L shape, and the head of the buckle wrench 5 is provided with a buckle head 51 that is buckled with the buckle groove, which may be folded in an L shape. In addition, a fulcrum portion 52 is provided in the middle of the buckle wrench, which has a shaft hole for rotationally connecting with the locking member, so that the buckle wrench can be moved up and down.

[0042] As an embodiment, the locking member 4 is a steel ring. Moreover, the steel ring is an inverted isosceles trapezoidal structure, and the buckle wrench 5 is connected to the upper bottom edge of the steel ring through the shaft hole of the fulcrum portion 52. A long hole 32 is provided on one side of the opening, which serves as the annular closed shaft point of the locking member, and the lower bottom edge of the steel ring is connected to the long hole. While the steel ring is rotated downward to pass over the buckle groove, the buckle wrench is rotated to fasten the buckle head and the buckle groove. Since the steel ring has a relatively large deformation, it can not only increase the reliability of the locking in the locked state, but also can achieve a more convenient unlocking with the help of deformation when unlocking.

[0043] In order to facilitate installation and ensure the clamping effect, the clamp body 3 is made of metal and has elasticity. For example, it is made of stainless steel. In this way, during the installation process, the opening is opened with the help of elasticity, and the clamp body is initially clamped on the square tube purlin and the U-shaped part of the middle pressure block, which facilitates installation. After the snap-on wrench is buckled, the elastic energy makes the snap-on wrench and the buckling part have a larger buckling force, thereby enhancing the reliability of fixation.

[0044] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes but is not limited to the contents described in the drawings and the above specific implementation. Any modification that does not deviate from the functional and structural principles of the utility model will be included in the scope of the claims.
