Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic panel installation, and in particular to a clamp for installing a photovoltaic panel mounted on a wall. Background Art

[0002] As a new type of renewable energy, solar energy has the advantages of being inexhaustible and pollution-free, so it has become an energy source favored by many industries. In the construction industry, the idea of ​​photovoltaic building integration came into being. Photovoltaic building integration is a technology that integrates solar power generation products into buildings, that is, through the roof and facade of the building and the photovoltaic power generation device, the building itself can use solar energy to generate electricity to meet its own electricity needs. It is an emerging energy-saving building form that conforms to the green and low-carbon development concept.

[0003] At present, photovoltaic modules are mostly integrated with buildings on the roofs of buildings, and are rarely used on the facades of buildings. Therefore, vertical photovoltaic panels with integrated walls are proposed. By hanging photovoltaic panels on the walls of buildings, solar energy can be utilized to a greater extent. When installing photovoltaic panels, it is necessary to connect and fix adjacent photovoltaic panels with clamps so that multiple photovoltaic panels form a whole. However, the existing vertical photovoltaic panel clamps cannot ensure good coordinated movement between the wall and the photovoltaic panel during an earthquake, and the photovoltaic panel may fall and cause secondary damage. Summary of the invention

[0004] The present invention provides a fixture for installing a wall-mounted photovoltaic panel, aiming to solve the problem that the existing neutral photovoltaic panel cannot coordinate well with the wall during an earthquake, so that the photovoltaic panel has a certain space for movement and coordination.

[0005] The present invention is achieved through the following technical scheme: a clamp for installing a photovoltaic panel mounted on a wall, comprising a clamp body, the clamp body comprising a connector, a clamping piece and a fastener, the clamping piece is connected to one side of the connector, the clamping piece comprises an upper clamping plate, a lower clamping plate and a vertical plate, the two ends of the vertical plate are respectively connected to the upper clamping plate and the lower clamping plate, a U-shaped groove is formed between the vertical plate, the upper clamping plate and the lower clamping plate, one side of the photovoltaic panel can be inserted into the U-shaped groove; a connecting hole is opened on the connector, the connecting hole is in the shape of a long strip, the fastener passes through the connecting hole in sequence and is fastened to the wall.

[0006] Compared with the prior art, this solution has the following advantages and beneficial effects:

[0007] In this solution, the edge of the photovoltaic panel is clamped by the clamping piece in the clamp body, and the fastener is inserted into the long hole on the connecting body, so that the fastener fastens the entire clamp body to the wall steel, thereby achieving the function of limiting and fixing the photovoltaic panel.

[0008] At the same time, since the connecting hole in this solution is in the shape of a long hole, a certain amount of free space is reserved between the long hole and the fastener, so that the fastener has the tendency and state to move freely in the long hole, thereby giving the clamp sufficient freedom, so that the photovoltaic panel can better coordinate movement with the cold-bent wall. In this way, the wall will undergo slight displacement during an earthquake, and the photovoltaic panel can better coordinate movement with the thin-walled cold-bent wall through the clamp in this solution, thereby ensuring the effectiveness and reliability of the entire device.

[0009] Furthermore, the connecting body includes an upper connecting plate and a lower connecting plate, the clamping member is connected to the upper connecting plate and the lower connecting plate, and the upper connecting plate and the lower connecting plate are both provided with the connecting holes arranged vertically opposite to each other.

[0010] Beneficial effect: In this solution, the connecting body includes an upper connecting plate and a lower connecting plate, and the clamping piece is connected to the upper connecting plate and the lower connecting plate, so that a hollow structure is formed between the connecting body and the clamping piece, which can make the weight of the entire clamp lighter, easier to carry and easier to install and operate.

[0011] Furthermore, the fasteners are bolts and nuts, and the screw rods of the bolts sequentially pass through the connection holes of the upper connection plate, the connection holes of the lower connection plate and the steel sections on the wall and are fixed by nuts.

[0012] Beneficial effect: In this solution, the fasteners are bolt and nut structures, which have low cost and are easy to construct and operate.

[0013] Furthermore, an upper surface of the upper connecting plate is lower than an upper surface of the clamping member.

[0014] Beneficial effect: With such an arrangement, after tightening the bolt, the bolt head can be located on the upper connecting plate and below the upper surface of the clamp or flush with the upper surface of the clamp, which can shield the bolt head, thereby making the surface formed after the photovoltaic panel is installed more beautiful and smooth.

[0015] Furthermore, rubber pads are connected to the sides of the upper clamping plate and the lower clamping plate that face each other.

[0016] Beneficial effect: The photovoltaic panel is connected to the clamp through the rubber pad, and the photovoltaic panel can perform a small deflection movement by compressing the rubber pad, which better protects the structural integrity of the photovoltaic panel and ensures that the photovoltaic panel can work normally.

[0017] Furthermore, heat-insulating glue is provided between the rubber pad of the upper clamping plate and the upper clamping plate, and between the lower clamping plate and the rubber pad.

[0018] Beneficial effects: The heat-insulating adhesive in this solution can not only fix the rubber pad on the upper clamping plate and the lower clamping plate, but also play a certain heat-insulating role.

[0019] Furthermore, the clamp body includes a side clamp and a middle clamp. The middle clamp has two clamps, which are respectively connected to two sides of the connector. The side clamp has only one clamp.

[0020] Beneficial effects: The side clamps and middle clamps in this solution can be applied to the installation of vertical photovoltaic panel structures. After multiple photovoltaic panels are spliced ​​and assembled, the side clamps are used to clamp and fix the outside of the multi-layer gravel photovoltaic panel, while the middle clamps are used to clamp and fix between two adjacent vertical photovoltaic panels. In this way, the joint action of the side clamps and the middle clamps can make the overall structure of the assembled photovoltaic panels more secure.

[0021] The middle clamp in this solution can simultaneously connect the upper and lower adjacent photovoltaic panels, as well as the left and right adjacent photovoltaic panels, to ensure that the upper and lower photovoltaic panels and the left and right photovoltaic panels can move well during an earthquake, and can be used for multi-layer vertical photovoltaic panel structures.

[0022] Furthermore, the two clamping members of the middle clamp are respectively a left clamping member and a right clamping member, and the left clamping member and the right clamping member are respectively horizontally slidably matched with the connecting body, and a reset member is connected between the vertical plates of the left clamping member and the right clamping member and the connecting body; one end of the lower clamping plate of the left clamping member and the right clamping member is provided with a guide slope, and the guide slopes of the left clamping member and the right clamping member are inclined from top to bottom toward the connecting body.

[0023] Beneficial effect: In the present solution, the left clamp and the right clamp in the middle clamp respectively cooperate with the connecting body in horizontal sliding, so that when the middle clamp needs to be installed in the gap between two adjacent photovoltaic panels, the photovoltaic panels are directly laid flat, a gap is reserved in advance, and then the middle clamp is inserted into the gap between the two adjacent photovoltaic panels. During the insertion of the middle clamp, the guide inclined surfaces of the lower clamping plates of the left clamp and the right clamp first contact the frames of the two adjacent photovoltaic panels, and exert an extrusion and pushing effect on the left clamp and the right clamp, so that the left clamp and the right clamp slide toward the connecting body until the lower clamps of the left clamp and the right clamp completely pass the bottom of the photovoltaic panel. The left clamp and the right clamp will be reset under the action of the reset member, and the photovoltaic panel can be located in the U-shaped groove of the left clamp and the right clamp.

[0024] This solution provides another method of installing a clamp on a photovoltaic panel. This method is simple to operate and can be used to first lay out adjacent photovoltaic panels and then install the clamp. The operation is simple and convenient, and the operation efficiency is higher.

[0025] Furthermore, during the process of inserting the fastener downward into the connecting hole, the head of the fastener can push the left clamping member and the right clamping member to slide in the direction away from the connecting body; the upper clamping member and the lower clamping member in the left clamping member and the right clamping member are provided with vertically opposite give-way grooves, and wedge blocks are slidably fitted in the give-way grooves, and an elastic member is connected between the wedge blocks and the give-way grooves, and the inclined surfaces of the wedge blocks on the upper clamping plate and the inclined surfaces of the wedge blocks on the lower clamping plate form an eight-shaped expansion shape.

[0026] Beneficial effect: In this scheme, when two adjacent photovoltaic panels are located in the U-shaped groove formed between the upper clamp and the lower clamp, the head of the fastener pushes the left clamp and the right clamp to slide away from the connector during the process of inserting the fastener downward into the connecting hole. In this way, the inclined surface of the wedge block can contact the photovoltaic panel and play a role in pressing and limiting the photovoltaic panel, thereby improving the clamping and limiting effect of the photovoltaic panel. In this way, the wedge blocks on the upper and lower clamps can be adaptively adjusted according to photovoltaic panels of different thicknesses under the action of the elastic member, so as to adapt to the clamping effect of photovoltaic panels of different thicknesses. In addition, under the action of the elastic member, the photovoltaic panel has a certain range of activity during an earthquake, which can play a role in shock absorption.

[0027] Further, the connector includes an upper connecting plate, a lower connecting plate and two fixing plates, the two fixing plates are respectively located on both sides of the connecting hole, and the two ends of the fixing plates are respectively connected to the upper connecting plate and the lower connecting plate;

[0028] The upper connecting plate and the lower connecting plate are both provided with sliding grooves, the upper and lower parts of the left clamping member and the right clamping member are both connected with sliding plates, the bottom ends of the sliding plates are both connected with sliding blocks, and the sliding blocks are located in the sliding grooves and slidably cooperate with the sliding grooves;

[0029] The two slides located on the upper part of the left clamp and the right clamp are provided with slide slopes at the ends facing each other, and the two slide slopes form an eight-shaped flared shape. When the head of the fastener moves downward, it can gradually contact the slide slopes and push the two slides to slide away from the connecting body.

[0030] Beneficial effect: In this solution, the upper and lower parts of the left clamp and the right clamp are equipped with slide plates, and the slide plates cooperate with the slide grooves on the upper connecting plate and the lower connecting plate, so as to provide a guide for the sliding of the left clamp and the right clamp. At the same time, in this solution, a slide plate inclined surface is provided at one end of the two slide plates facing each other, so that when the fastener is inserted into the connecting hole downward, the head of the fastener can smoothly enter between the two slide plates and easily contact with the inclined surface of the slide plate to gradually push the two left clamp and the right clamp to slide.

The exemplary embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.

[0041] Example 1

[0042] like Figure 1-Figure 2As shown, this embodiment 1 provides a clamp for installing a photovoltaic panel mounted on a wall, including a clamp body, the clamp body including a connector, a clamping member 4 and a fastener, the clamping member 4 is connected to one side of the connector, the clamping member 4 includes an upper clamping plate 401, a lower clamping plate 402 and a vertical plate 403, the two ends of the vertical plate 403 are respectively connected to the upper clamping plate 401 and the lower clamping plate 402 as a whole, a U-shaped groove is formed between the vertical plate 403, the upper clamping plate 401 and the lower clamping plate 402, one side of the photovoltaic panel 10 can be inserted into the U-shaped groove, and the U-shaped groove is used to clamp the frame of the photovoltaic panel 10; a connecting hole is provided on the connector, and in this embodiment, the connecting hole is in the shape of a long hole, and the fasteners pass through the connecting hole in sequence and are fastened to the wall. Since the connecting hole is in the shape of a long hole, a gap is retained between the fastener and the connecting hole after passing through the connecting hole, and there is a movable space. Specifically:

[0043] In this embodiment, the clamp body includes a side clamp 100 and a middle clamp 200, and the middle clamp 200 is provided with two clamping members 4, and the two clamping members 4 of the middle clamp 200 are respectively a left clamping member 41 and a right clamping member 42, and the two clamping members 4 are respectively connected to the two sides of the connector, and the side clamp 100 is provided with one clamping member 4, so that the middle clamp 200 is a double-sided clamping structure, and the side clamp 100 is a single-sided clamping structure, wherein the middle clamp 200 is used to hold two adjacent photovoltaic panels 10, and the side clamp 100 is mainly used to clamp the edge of the entire photovoltaic panel 10 structure after assembly. The cooperation between the side clamp 100 and the middle clamp 200 can improve the reliability and stability of the entire photovoltaic panel 10 structure after assembly.

[0044] In this embodiment, the connector includes an upper connecting plate 1 and a lower connecting plate 2, and the clamping member 4 is interconnected with the upper connecting plate 1 and the lower connecting plate 2. In this embodiment, a fixing plate 3 is also vertically fixedly connected between the upper connecting portion and the lower connecting plate 2. The vertical plate 403 in the clamping member 4 is bonded, welded or screwed to the fixing plate 3. The upper connecting plate 1 and the lower connecting plate 2 are both provided with connecting holes arranged vertically opposite to each other. In this embodiment, the connecting hole on the upper connecting plate 1 is an upper long strip hole 6, and the connecting hole on the lower connecting plate 2 is a lower long strip hole 7.

[0045] The fasteners in this embodiment are bolts 8 and nuts 9, and the screw rod 802 of the bolt 8 passes through the upper long hole 6, the lower long hole 7 and the steel on the wall in sequence and is fixed by the nut 9. In this embodiment, the upper surface of the upper connecting plate 1 is lower than the upper surface of the clamping member 4, that is, the upper surface of the upper connecting plate 1 is located below the upper surface of the upper clamping plate 401, so that when the bolt 8 is tightened, the upper clamping plate 401 can shield the bolt head 801, so that the photovoltaic panel 10 formed after assembly can be more flat and beautiful.

[0046] In this embodiment, rubber pads 5 are connected to the sides of the upper splint 401 and the lower splint 402 that are directly opposite to each other, and thermal insulation glue is provided between the rubber pad 5 of the upper splint 401 and the upper splint 401, and between the rubber pad 5 of the lower splint 402 and the lower splint 402, so that the rubber pad 5 is connected to the upper splint 401 and the lower splint 402 through the thermal insulation glue, and the thermal insulation glue can play a certain thermal insulation role.

[0047] The specific implementation process is as follows:

[0048] Combination Figure 3 and Figure 4 As shown, a clamp for installing a wall-mounted photovoltaic panel 10 in this embodiment is divided into a side clamp 100 and a middle clamp 200. The side clamp 100 is used to clamp and fix the outer side of the multi-layer vertical photovoltaic panel 10, and the middle clamp 200 is used to clamp and fix between two adjacent vertical photovoltaic panels 10.

[0049] The photovoltaic panel 10 in this embodiment is installed on a wall. In this embodiment, it is connected to a cold-bent thin-walled wall. When in use, holes for the bolts 8 to pass through are first reserved on the flanges of the cold-bent thin-walled steel section 11 and the OSB board 12 on the cold-bent wall. When in use, the long hole-shaped connecting holes on the connector are placed corresponding to the holes, and the rubber pads 5 on the upper clamping plate 401 and the lower clamping plate 402 are respectively abutted against the top and side surfaces of the photovoltaic panel 10, thereby protecting the photovoltaic panel 10.

[0050] Insert the U-shaped groove of the side clamp 100 into the edge of the photovoltaic panel 10, and insert the U-shaped grooves on the two clamps 4 on the middle clamp 200 between two adjacent photovoltaic panels 10, so that the connecting holes correspond to the holes on the corresponding positions on the wall, and then pass the bolts 8 through the upper strip holes, the lower strip holes and the holes on the flange of the OSB board or the cold-bent thin-walled steel 11 on the wall in sequence, and then tighten the nut 9 at the bottom of the screw 802 of the bolt 8 to achieve the connection of the clamp, so that the clamp can limit the position of the photovoltaic panel 10.

[0051] In this embodiment, the U-shaped groove of the clamping member 4 of the clamp is conveniently set on the photovoltaic panel 10 support frame, and the clamp itself is locked and fixed on the wall structure by the combination of bolts 8 and nuts 9. The clamp provided by this application can reduce damage to the photovoltaic panel 10 support frame. It is also unnecessary to find holes and align on the photovoltaic panel 10 support frame during installation, which makes the operation more convenient and efficient.

[0052] A wall-mounted photovoltaic panel 10 installation clamp in the present solution clamps the photovoltaic panel 10 and connects it to the cold-bent thin-walled wall structure. Since the connecting hole through which the bolt 8 passes is in the shape of an elongated strip, the clamp has a certain degree of freedom and can move in different directions, so that the photovoltaic panel 10 also has a certain degree of freedom. When the thin-walled cold-bent wall is slightly displaced during an earthquake, the photovoltaic panel 10 can better coordinate its movement with the thin-walled cold-bent wall through the wall-mounted photovoltaic panel 10 installation clamp of the present invention, thereby ensuring the effectiveness and reliability of the entire device.

[0053] Example 2

[0054] Combination Figure 5 As shown, a clamp for installing a photovoltaic panel mounted on a wall, the difference between this embodiment and embodiment 1 is that: the left clamp 41 and the right clamp 42 of the middle clamp 200 are respectively matched with the connecting body in horizontal sliding, and a reset member is connected between the vertical plate 403 of the left clamp 41 and the right clamp 42 and the connecting body; one end of the lower clamp plate 402 of the left clamp 41 and the right clamp 42 is provided with a guide slope 4021, and the guide slope 4021 of the left clamp 41 and the right clamp 42 is inclined from top to bottom toward the connecting body.

[0055] In this embodiment, the connector includes an upper connecting plate 1, a lower connecting plate 2 and two fixing plates 3. The two fixing plates 3 are respectively located on both sides of the connecting hole, and the two ends of the fixing plates 3 are respectively connected to the upper connecting plate 1 and the lower connecting plate 2.

[0056] The upper connecting plate 1 and the lower connecting plate 2 are both provided with a slide groove 15, the upper and lower parts of the left clamping member 41 and the right clamping member 42 are both connected with a slide plate 13, one end of the slide plate 13 is connected with a slider 14, and the slider 14 is located in the slide groove 15 and slidably cooperates with the slide groove 15.

[0057] The two slide plates 13 located on the upper part of the left clamping member 41 and the right clamping member 42 are provided with slide plate inclined surfaces 131 at the ends facing each other. The two slide plate inclined surfaces 131 form an eight-shaped flared shape. In the process of inserting the fastener downward into the connecting hole, the head of the fastener can push the left clamping member 41 and the right clamping member 42 to slide away from the connecting body. That is, when the bolt 8 moves downward through the connecting hole, its bolt head 801 can gradually contact the slide plate inclined surface 131 and push the two slide plates 13 to slide away from the connecting body.

[0058] In this embodiment, the reset member is a spring. When the reset member is not subjected to pressure, there is a gap between the slider 14 and both sides of the slide groove 15, thereby ensuring that the slide plate 13 has space to move leftward and rightward.

[0059] During use, when it is necessary to install the middle clamp 200 in the gap between two adjacent photovoltaic panels 10, the photovoltaic panels 10 can be laid flat to leave gaps between the adjacent photovoltaic panels 10 in advance, and then the middle clamp 200 can be inserted into the gap between the two adjacent photovoltaic panels 10. During the insertion of the middle clamp 200, the guide slopes 4021 of the lower clamping plates 402 of the left clamp 41 and the right clamp 42 first contact the frames of the two adjacent photovoltaic panels 10, and exert an extrusion and pushing effect on the left clamp 41 and the right clamp 42, so that the left clamp 41 and the right clamp 42 slide toward the connecting body until the lower clamping plates 402 of the left clamp 41 and the right clamp 42 completely pass over the bottom of the photovoltaic panel 10. Then, the left clamp 41 and the right clamp 42 will be reset under the action of the reset member, and the photovoltaic panel 10 can be located in the U-shaped groove of the left clamp 41 and the right clamp 42.

[0060] Then insert the bolt 8 into the connecting hole to lock it. During the downward movement of the bolt 8, when the bolt head 801 contacts the two slide slopes 131, it will push the left clamping member 41 and the right clamping member 42 to move, so that the photovoltaic panel 10 can be located in the U-shaped groove of the left clamping member 41 and the right clamping member 42 with a larger area, which has a better clamping and limiting effect on the photovoltaic panel 10.

[0061] Example 3

[0062] Combination Figure 6 As shown, a clamp for installing a photovoltaic panel mounted on a wall, the difference between this embodiment and embodiment 2 is that: the upper clamp 401 and the lower clamp 402 in the left clamp 41 and the right clamp 42 are both provided with vertically opposite giving way grooves 17, and the giving wedge blocks 18 on the upper clamp 401 and the wedge blocks 18 on the lower clamp 402 are symmetrically arranged, the giving way grooves 17 are slidably fitted with wedge blocks 18, and an elastic member is connected between the wedge blocks 18 and the giving way grooves 17. The elastic member in this embodiment is a spring, and the inclined surface of the wedge block 18 on the upper clamp 401 and the inclined surface of the wedge block 18 on the lower clamp 402 form an eight-shaped expansion shape.

[0063] In this embodiment, the end of the wedge block 18 away from the give way groove 17 is a plane. When the bolt head 801 pushes the two slide plates 13 to slide to the left and right respectively, the photovoltaic panel 10 can pass over the inclined surface of the wedge block 18 and be located on the plane of the wedge block 18. In this way, the plane of the wedge block 18 can form a surface contact with the photovoltaic panel 10, and the contact area is larger. This can protect the photovoltaic panel 10 and prevent the photovoltaic panel 10 from being in line contact with the inclined surface of the wedge block 18, which may cause a large squeezing force on the photovoltaic panel 10 and cause damage.

[0064] When in use, after the lower clamping plate 402 in this embodiment passes through the bottom end of the photovoltaic panel 10, the photovoltaic panel 10 is located between the upper clamping plate 401 and the lower clamping plate 402, and then the bolt 8 is inserted into the connecting hole. When the bolt head 801 contacts the inclined surface 131 of the slide plate, it will gradually push the left clamping member 41 and the right clamping member 42 to move to the left and right respectively, so that the wedge blocks 18 on the upper clamping plate 401 and the lower clamping plate 402 contact with the photovoltaic panel 10 and produce a state of retracting toward the direction of the yield groove 17. When the bolt head 801 moves into place, it will limit the two slide plates 13. At this time, the slide plate 13 will no longer move, so that the wedge blocks 18 on the upper clamping plate 401 and the lower clamping plate 402 have a better limiting effect on the photovoltaic panel 10.

[0065] Due to the arrangement of the elastic member between the wedge block 18 and the clearance groove 17, the photovoltaic panel 10 has a certain buffering effect and a certain vibration reduction effect during an earthquake. At the same time, the upper and lower wedge blocks 18 can also adapt to photovoltaic panels 10 with different thicknesses, so that the intermediate clamp 200 in this solution has a wider range of uses and is more flexible.
