Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic assembly installation, and in particular to a sliding device for a photovoltaic assembly and a construction method thereof. Background Art

[0002] As a renewable energy source, solar energy plays an irreplaceable role in the long-term development of energy strategies. Photovoltaic power generation is a technology that uses photovoltaic panels to receive solar energy to generate electricity. Existing photovoltaic brackets are of many types and complex forms, and the traditional installation method requires the panel components to be installed one by one, which is extremely inefficient. At the same time, how to safely and reliably install photovoltaic panels in places with complex construction environments such as large-span mountainous areas or sewage treatment plants where construction is difficult becomes a construction problem.

[0003] The Chinese invention patent with publication number "CN117955417A" is specifically "a sliding device for photovoltaic modules and a construction method thereof". Although it uses a small sliding connector to use the steel cable as a sliding track, it does not need to increase too much additional material costs, reduces the cost of construction and installation, and has high economic benefits. Through simple sliding operations, it avoids the complicated procedures of traditional installation, is convenient for construction, and shortens the construction period of photovoltaic panel installation;

[0004] However, the photovoltaic panel assembly connector which is slidably arranged on the steel cable can only adjust the width between two photovoltaic panel assemblies on the same steel cable, and is not convenient for adjusting the spacing between the photovoltaic panel assembly connectors on the two steel cables. This means that it can only allow photovoltaic panels of different widths to be effectively adapted and installed, and cannot allow photovoltaic panels of different lengths to be effectively adapted and installed, resulting in a problem of poor installation adaptation performance. In addition, the photovoltaic panel assembly connector and the steel cable are tightened and fixed with multiple bolts, and there are many operating steps, which is not suitable for high-altitude operations. Summary of the invention

[0005] In view of the above-mentioned shortcomings of the prior art, the present invention provides a sliding device for a photovoltaic module and a construction method thereof, which can effectively solve the problem of the inconvenience of using the prior art.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0008] Furthermore, both ends of the two steel cables are anchored to supports, and the four supports are located in the same horizontal plane and are distributed in a rectangular array with respect to each other.

[0009] Furthermore, a rotating cavity is provided at the top of several of the upper slide seats, a rotating block is rotatably installed in the rotating cavity, the bottom of the screw rod extends into the rotating cavity and is vertically fixed at the center of the top of the rotating block, several of the upper slide seats are penetrated by two square holes symmetrically distributed about the center of the screw rod, the two insertion rods are respectively adapted to penetrate the corresponding square holes, and the inner arc walls of several of the upper slide seats are embedded with rolling installations.

[0010] Furthermore, several of the two insertion rods are provided with insertion holes on the sides facing each other, and the two ends of the shaft rods away from each other are respectively adapted to be inserted into the corresponding insertion holes. When the upper sliding seat and the lower sliding seat are combined to form a circular hole, the tops of the corresponding two insertion rods are squeezed and contacted with the lower bottom of the same support plate, and the inner arc walls of several of the lower sliding seats are provided with anti-slip convex patterns.

[0011] Furthermore, the two docking assemblies also include springs installed in the two shaft cylinders, and the two springs are fixedly connected to the corresponding shaft rods at one end away from each other. A shift rod is vertically fixedly installed on the outer rod wall of the shaft rod, and the two shift rods are respectively arranged to contact the corresponding insertion rods.

[0012] Furthermore, a first sliding groove is provided on the top of the mounting seat, a first sliding seat is slidably installed in the first sliding groove, a second sliding seat is vertically fixedly installed on the top of the first sliding seat, a second sliding groove is provided on the top of the second sliding seat and is vertically distributed in a different plane from the first sliding groove, and the bottom of the slider is limitedly slidably installed in the second sliding groove.

[0013] Furthermore, several of the sliders are provided with threaded holes on their tops, several of the support plates are provided with clipping grooves on their tops, the four corners of the photovoltaic panels are respectively clipped into the corresponding clipping grooves, several of the clipping grooves are provided with round holes on their tops, screws are threadedly installed in the round holes, the screws are threaded through the corresponding photovoltaic panels, and the threads are inserted into the corresponding threaded holes.

[0014] The invention discloses a sliding device construction method for photovoltaic modules, including two steps of pre-installation debugging and position limiting installation.

[0015] Furthermore, the pre-installation debugging includes the following contents:

[0016] First, four supports are welded in pairs on the corresponding mounting frame in a rectangular arrangement, and then the two ends of the two steel cables are anchored on the corresponding supports respectively, so that the two steel cables are parallel to each other and serve as sliding tracks for the photovoltaic panels.

[0017] Secondly, buckle several upper slide seats invertedly onto the corresponding steel cables, and place the corresponding lower slide seats under the upper slide seats, and make the two insertion rods on the top of the lower slide seats penetrate the upper slide seats;

[0018] Then, press the two levers respectively to drive the corresponding shaft rods to squeeze the corresponding springs. At this time, keep the upper slide seat still and move the lower slide seat, so that the distance between the upper slide seat and the lower slide seat is gradually reduced, and finally the two shaft rods are respectively opposite to the corresponding insertion holes. Then release the levers, and the elastic restoring force provided by the springs pushes the corresponding shaft rods into the corresponding insertion holes, completing the temporary fixation between the lifting seat and the lower slide seat;

[0019] Finally, by embedding the rolling ball on the inner arc wall of the lower bottom of the upper slide seat, rolling contact is made with the surface of the steel cable, so that several upper slide seats and the corresponding lower slide seats and support plates can be synchronously moved and adjusted on the surface of the steel cable, and the distance between two adjacent upper slide seats on the same steel cable can be adjusted according to the width of the photovoltaic panel;

[0020] Furthermore, the position limiting installation includes the following contents:

[0021] First, after the positions of the two adjacent upper slide seats on the same steel cable are adjusted, the top of the upper slide seat is adjusted according to the specifications of the photovoltaic panel to obtain the specific position of the support plate in the current horizontal plane. The specific method is to keep the second slide seat stationary and directly move the support plate. At this time, the sliding block detachably installed at the bottom of the support plate slides linearly in the second slide seat to complete the lateral horizontal position adjustment of the support plate. Then, the support plate and the second slide seat are kept from sliding relative to each other, and the mounting seat is kept stationary, and the support plate and the second slide seat are directly moved at the same time to complete the longitudinal horizontal position adjustment of the support plate.

[0022] Secondly, place the four corners of the photovoltaic panel to be installed on the corresponding support plate;

[0023] Then, since the lifting seat is threadedly sleeved on the outer rod wall of the screw rod, and the lifting seat is temporarily fixed with the two plug rods at this time, and the two plug rods slide through the corresponding upper sliding seat, rotating the screw rods counterclockwise for a number of times will only drive the lifting seat up and down, thereby driving the lower sliding seat to rise in height until the anti-slip convex pattern on the inner arc wall at the top of the lower sliding seat is fully fitted and tightly engaged with the surface of the steel cable. When the lower sliding seat is in tight contact with the steel cable, the tops of the two plug rods rise to a position where they are pressed and resisted against the bottom of the same support plate, thereby completing the locking and fixing of the upper and lower sliding seats, and also completing the position fixing of the support plate, thus completing the limit fixing of the photovoltaic panel;

[0024] Finally, the steel cable is tensioned to control its deflection within 1%.

[0025] Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects:

[0026] 1. The support plate used to hold the photovoltaic panel is designed to be flexibly adjusted in the horizontal and vertical directions on the horizontal plane, so that the device can be used not only for the effective installation of photovoltaic panels of different widths, but also for the effective installation of photovoltaic panels of different lengths, and has the characteristics of strong installation adaptability;

[0027] 2. Abandon the traditional tightening and fixing method of installing with multiple bolts, the locking and fixing between the upper slide and the steel cable is completed by moving and tightening the lower slide seat, and as the height of the lower slide seat rises, it can also squeeze and contact the bottom of the support plate used to clamp the photovoltaic panel, thereby completing the locking and fixing of the support plate adjusted to the installation position. The entire installation process between the photovoltaic panel and the sliding device only needs to rotate the screw clockwise, which is simple to operate and suitable for high-altitude operations.

[0054] The remaining structure is the same as that of Example 2.

[0055] Example 4

[0056] Reference Figure 1-7 , which is the fourth embodiment of the present invention, is a method for constructing a sliding device for a photovoltaic module, including two steps of pre-installation debugging and position-limiting installation.

[0057] Pre-installation commissioning includes the following:

[0058] First, four supports 1 are welded in pairs on the corresponding mounting frame in a rectangular distribution, and then the two ends of the two steel cables 2 are anchored on the corresponding supports 1, so that the two steel cables 2 are parallel to each other and serve as sliding tracks for the photovoltaic panels 3. The spacing between the two steel cables 2 is kept fixed by fixing the supports 1, but it does not affect the effective installation of the subsequent photovoltaic panels 3 of different lengths;

[0059] Secondly, several upper slides 51 are inverted and buckled onto the corresponding steel cables 2, and the corresponding lower slides 61 are placed under the upper slides 51, and the two insertion rods 62 on the top of the lower slides 61 pass through the upper slides 51. At this time, the upper and lower slides are surrounded by a hole, but the hole is not a final round hole. At this time, the lower slide 61 has not yet been squeezed and conflicted with the surface of the steel cable 2, so it is convenient to adjust the position of the upper slide 51 through several balls on the inner arc wall of the lower bottom of the upper slide 51;

[0060] Then, the two levers 74 are pressed respectively, driving the corresponding shaft rods 72 to squeeze the corresponding springs 73. The shaft rods 72 are always slidably installed in the shaft tube 71. At this time, the upper slide seat 51 is kept stationary and the lower slide seat 61 is moved, so that the distance between the upper slide seat 51 and the lower slide seat 61 is gradually reduced, and finally the two shaft rods 72 are respectively opposite to the corresponding insertion holes 63. Then the levers 74 are released, and the elastic restoring force provided by the springs 73 pushes the corresponding shaft rods 72 to be inserted into the corresponding insertion holes 63, completing the temporary fixation between the lifting seat 53 and the lower slide seat 61.

[0061] Finally, by embedding a rolling ball on the inner arc wall of the lower bottom of the upper slide 51, it rolls in contact with the surface of the steel cable 2, making it convenient for several upper slides 51 and the corresponding lower slides 61 and the support plate 4 to synchronously move and adjust their positions on the surface of the steel cable 2. The distance between two adjacent upper slides 51 on the same steel cable 2 is adjusted according to the width of the photovoltaic panel 3. When the upper slide 51 slides on the steel cable 2, the lower slide 61 also slides synchronously, which can prevent the lower slide 61 from falling off or being misaligned with the upper slide 51, affecting the subsequent limit fixation.

[0062] The limit installation includes the following contents:

[0063] First, after the positions of the two adjacent upper slide seats 51 on the same steel cable 2 are adjusted, the top of the upper slide seat 51 is adjusted according to the specifications of the photovoltaic panel 3 to obtain the specific position of the support plate 4 in the current horizontal plane. The specific method is to keep the second slide seat 84 stationary and directly move the support plate 4. At this time, the sliding block 86 detachably installed at the bottom of the support plate 4 slides linearly in the second slide seat 84 to complete the lateral horizontal position adjustment of the support plate 4. Then, the support plate 4 and the second slide seat 84 are kept from sliding relative to each other, and the mounting seat 81 is kept stationary, and the support plate 4 and the second slide seat 84 are directly moved at the same time to complete the longitudinal horizontal position adjustment of the support plate 4.

[0064] Secondly, the four corners of the photovoltaic panel 3 to be installed are respectively clamped on the corresponding support plate 4. Since several support plates 4 are detachable and replaceable, corresponding support plates 4 can be selected for different types of photovoltaic panels 3, and the contact surface between the photovoltaic panel 3 and the support plate 4 can be smeared with adhesive glue to improve the installation stability of the photovoltaic panel 3 and the support plate 4 in the air;

[0065] Then, since the lifting seat 53 is threadedly mounted on the outer rod wall of the screw rod 52, and the lifting seat 53 is temporarily fixed with the two plug rods 62 at this time, and the two plug rods 62 slide through the corresponding upper slide seat 51, rotating the screw rods 52 counterclockwise for a certain number of times will only drive the lifting seat 53 to rise, thereby driving the lower slide seat 61 to rise in height until the anti-slip convex pattern of the inner arc wall at the top of the lower slide seat 61 is fully fitted and tightly engaged with the surface of the steel cable 2. When the lower slide seat 61 is in tight contact with the steel cable 2, the tops of the two plug rods 62 rise to a position where they are pressed and resisted against the bottom of the same support plate 4, so that while the upper and lower slide seats are locked and fixed, the position of the support plate 4 is also fixed, and the limit fixation of the photovoltaic panel 3 is also completed;

[0066] Finally, the steel cable 2 is tensioned to control its deflection within 1%.

[0067] The remaining structure is the same as that of Example 3.

[0068] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.

Then, the support plate (4) and the second slide seat (84) are kept from sliding relative to each other, and the mounting seat (81) is kept stationary, and the support plate (4) and the second slide seat (84) are directly moved simultaneously to complete the longitudinal horizontal position adjustment of the support plate (4); Secondly, the four corners of the photovoltaic panel (3) to be installed are respectively clamped on the corresponding support plate (4); Then, since the lifting seat (53) is threadedly mounted on the outer rod wall of the screw rod (52), and the lifting seat (53) is temporarily fixed to the two plug rods (62) at this time, and the two plug rods (62) slide through the corresponding upper slide seat (51), counterclockwise rotation of the screw rods (52) will only drive the lifting seat (53) to rise and fall, thereby driving the lower slide seat (61) to rise in height until the anti-skid convex pattern of the inner arc wall at the top of the lower slide seat (61) is fully fitted and tightly engaged with the surface of the steel cable (2). When the lower slide seat (61) is in tight contact with the steel cable (2), the tops of the two plug rods (62) rise to a position where they are squeezed and resisted by the bottom of the same support plate (4), so that while the upper and lower slide seats are locked and fixed, the position of the support plate (4) is also fixed, and the limit fixation of the photovoltaic panel (3) is also completed; Finally, the steel cable (2) is tensioned so that its deflection is controlled within 1%.
