Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic construction, and in particular relates to a pole fixing device for a photovoltaic inverter trough box. Background Art

[0002] At present, the construction and supporting equipment of photovoltaic projects are in a period of great perfection. The inverter has gradually evolved from the original large cabinet inverter to a small and easy-to-install hanging box inverter. Its fixing method has also evolved from concrete fixing to double rear column hanging fixing. Specifically, concrete fixing refers to drilling holes in the concrete wall, installing the backboard, and then connecting the fixing components of the inverter with the backboard to achieve the effect of hanging the inverter. However, this installation method is limited by the site. For open outdoor areas without concrete walls, this method is not applicable.

[0003] The rear column hanging fixation means: first determine the installation location, harden the ground at the installation location, fix two columns on the ground, and then fix two horizontal connecting rods between the columns. Fix the back plate and the two horizontal connecting rods together by drilling holes in the two horizontal connecting rods, and finally connect the fixing components of the inverter to the back plate. This fixing process is relatively complicated, resulting in low installation efficiency; and fixing the inverter outdoors requires high strength and stability of the fixing column, resulting in high installation costs.

[0004] In summary, existing devices for fixing inverters outdoors have problems of low fixing efficiency and high cost. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a pole fixing device for a photovoltaic inverter trough box in view of the deficiencies in the above-mentioned prior art, which has a simple structure, low manufacturing cost, high installation efficiency and is easy to promote and use.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A pole fixing device for a photovoltaic inverter trough box, comprising a clamping ring and a plug-in structure, wherein the clamping ring is used to be fixed on a column of a photovoltaic bracket;

[0008] The clamping ring includes a mounting surface arranged on the outside;

[0009] The plug-in structure includes a horizontal bolt, a vertical bolt, a U-shaped card slot, and an L-shaped socket fixing plate. The U-shaped card slot includes a bottom plate and side plates vertically connected to both sides of the bottom plate. Baffles extend inward from both side plates. The bottom plate is fixedly connected to the installation surface to achieve the fixed connection between the snap ring and the U-shaped card slot. The L-shaped socket fixing plate includes a horizontal plate, a vertical plate perpendicularly connected to one end of the horizontal plate, a horizontal hole opened on the horizontal plate, and a vertical hole opened on the center line of the vertical plate. The vertical plate extends into the U-shaped card slot to achieve the horizontal fixation between the U-shaped card slot and the L-shaped socket fixing plate. The horizontal plate is placed on the snap ring, and blind holes are correspondingly opened on the snap ring. The horizontal bolt passes through the horizontal hole and the blind hole to achieve the fixed connection between the horizontal plate and the snap ring. Screw holes are opened on the engineering installation part for fixing the inverter, and screws pass through the screw holes and the vertical holes to achieve the fixed connection between the L-shaped socket fixing plate and the engineering installation part.

[0010] The distance between the two side plates is less than or equal to the width of the vertical plate, and the width of the vertical plate is greater than the distance between the two baffles.

[0011] Furthermore, the hoop snap ring further includes a connecting bolt, a connecting nut, and two symmetrically arranged snap rings. One adjacent end of the two snap rings is connected by a steering shaft, and connecting pieces extend from the other adjacent ends. Connecting holes are opened on the connecting pieces, and the connecting bolt passes through the connecting holes and cooperates with the connecting nut to achieve the fastening connection between the two connecting pieces.

[0012] Furthermore, after the vertical plate extends into the U-shaped card slot, a threaded hole is opened on the bottom plate corresponding to the vertical hole for threaded cooperation with the screw.

[0013] Furthermore, there are two plug-in structures, symmetrically arranged on both sides of the hoop snap ring.

[0014] Furthermore, there are two vertical holes.

[0015] Furthermore, the distance between the two side plates is equal to the width of the vertical plate.

[0016] Furthermore, an anti-slip gasket is arranged on the inner side of the hoop snap ring.

[0017] Furthermore, screw holes are also opened on the horizontal electrical trough box or the vertical electrical trough box, and screws pass through the screw holes and the vertical holes to achieve the fixed connection between the L-shaped socket fixing plate and the horizontal electrical trough box or the vertical electrical trough box.

[0018] The present utility model has the following advantages compared with the prior art:

[0019] The pole fixing device for the photovoltaic inverter trough box of the present utility model is connected to the photovoltaic support column through a hoop clamp, and the hoop clamp is connected to the engineering installation part for fixing the inverter through a plug-in structure, achieving the effect of fixing the engineering installation part on the photovoltaic support column. Since the photovoltaic support column is an essential component of the photovoltaic equipment, compared with the prior art, the fixing cost of this solution is low, and during installation, the time for hardening the ground and fixing the installation column is saved. The hoop clamp and the plug-in structure are fixedly connected together in advance. During on-site construction, only the hoop clamp needs to be fixed on the column and the engineering installation part needs to be fixed on the plug-in structure to complete the assembly of the fixing device. Then, the inverter is installed on the engineering installation part in the existing manner to complete the installation of the inverter.

[0040] Embodiment of the pole fixing device for the photovoltaic inverter trough box:

[0041] As Figure 10 The existing installation method of the inverter 6 requires that the ground under the installation frame of the inverter 6 must be hardened, and the installation frame of the inverter 6 is required to have a certain compressive strength; this results in the problems of high installation cost and long construction period in the existing installation of the inverter 6. Since the columns of the photovoltaic installation frames of the existing photovoltaic panels are also required to have a certain compressive strength, the inverter 6 is installed on the existing columns to solve the problem of high cost; for this purpose, the following pole fixing device for the photovoltaic inverter 6 trough box is provided.

[0042] Since the existing inverter 6 is connected to two crossbars for installation, in order to eliminate the step of designing crossbars between the columns 7 of the photovoltaic bracket, a fixing device that can be directly connected to the columns 7 of the photovoltaic bracket is designed to reduce the installation time of the inverter 6, as Figure 1 shown, the pole fixing device for the slot box of the photovoltaic inverter 6 includes a hoop clamp 1 and a plug-in structure 2. The above-mentioned hoop clamp 1 is used to be fixed on the column 7 of the photovoltaic bracket. The hoop clamp 1 and the plug-in structure 2 are fixedly connected, and the plug-in structure 2 is used to connect the inverter 6, so as to achieve the effect of fixing the inverter 6 on the column 7 of the photovoltaic bracket by using this fixing device.

[0043] In order to facilitate installation, save time and improve efficiency, the hoop clamp 1 includes a connecting bolt 11, a connecting nut and two symmetrically arranged clamping rings 12. One adjacent end of the two clamping rings 12 is connected through a steering shaft 14, and the other adjacent ends are both extended with connecting pieces 15. Connecting holes are opened on the above-mentioned connecting pieces 15, and the connecting bolt 11 passes through the connecting holes and cooperates with the connecting nut to realize the tight connection of the two connecting pieces 15. In this way, during actual construction, only the end with the connecting piece 15 needs to be connected through the connecting bolt 11, and the other end is connected when the parts leave the factory, saving the time of fixing the hoop clamp 1 on the column 7 of the photovoltaic bracket.

[0044] In order to facilitate the fixed connection between the hoop clamp 1 and the plug-in structure 2, an installation surface 16 is arranged on the outside of the clamping ring 12.

[0045] As Figure 2 、 Figure 3 shown, the plug-in structure 2 includes a horizontal bolt 21, a vertical bolt 22, a U-shaped card slot 23 and an L-shaped socket fixing plate 24. The L-shaped socket fixing plate 24 is inserted into the U-shaped card slot 23 for connection. Through the horizontal bolt 21, the vertical movement of the L-shaped socket fixing plate 24 and the U-shaped card slot 23 is restricted, and the engineering installation part 3 is fixed on the plug-in structure 2 through the vertical bolt 22.

[0046] Specifically, the U-shaped card slot 23 includes a bottom plate 231 and side plates 232 vertically connected to both sides of the bottom plate 231. Two side plates 232 both extend inwards with baffles 233. The above-mentioned bottom plate 231 is fixedly connected to the installation surface 16 to realize the fixed connection between the clamping ring 12 and the U-shaped card slot 23. The L-shaped socket fixing plate 24 includes a horizontal plate 241, a vertical plate 242 vertically connected to one end of the horizontal plate 241, a horizontal hole 243 opened on the horizontal plate 241 and a vertical hole 244 opened on the center line of the vertical plate 242.

[0047] Among them, the vertical plate 242 extends into the U-shaped groove 23 to achieve horizontal fixation of the U-shaped groove 23 and the L-shaped socket fixing plate 24; the horizontal plate 241 is mounted on the clamping ring 12, and a blind hole 13 is opened on the corresponding clamping ring 12. The horizontal bolt 21 passes through the horizontal hole 243 and the blind hole 13 to achieve a fixed connection between the horizontal plate 241 and the clamping ring 12.

[0048] like Figures 4 - 9 As shown, a screw hole is provided on the engineering installation part 3 for fixing the inverter 6, and the screw passes through the screw hole and the vertical hole 244 to achieve a fixed connection between the L-shaped socket fixing plate 24 and the engineering installation part 3. Other photovoltaic-related equipment can also be connected to the fixing device by screws, thereby achieving the effect of connecting the related equipment to the column 7 of the photovoltaic bracket. For example, a horizontal electrical trough box 5 or a vertical electrical trough box 4 for accommodating hardware wires. A screw hole is provided on the horizontal electrical trough box 5 or the vertical electrical trough box 4, and the screw passes through the screw hole and the vertical hole 244 to achieve a fixed connection between the L-shaped socket fixing plate 24 and the horizontal electrical trough box 5 or the vertical electrical trough box 4. Depending on the quality of the equipment, two or more fixing devices can also be selected to stably connect a related equipment to the column 7 of the photovoltaic bracket.

[0049] In order to ensure that the vertical plate 242 is inserted into the U-shaped slot 23 and that the baffle 233 of the U-shaped slot 23 can limit the horizontal direction of the vertical plate 242, the spacing between the two side plates 232 is less than or equal to the width of the vertical plate 242, and the width of the vertical plate 242 is greater than the spacing between the two baffles 233.

[0050] In order to enable the screws to stably fix the engineering installation part 3 on the plug-in structure, after the vertical plate 242 extends into the U-shaped slot 23, a threaded hole 234 is opened on the bottom plate 231 at a position corresponding to the vertical hole 244 for threaded cooperation with the screw.

[0051] In order to increase the expansion capacity of the fixed device, the plug-in structure 2 includes two, which are symmetrically arranged on both sides of the clamp ring 1. One plug-in structure is used to connect the inverter 6, and the other plug-in structure is used to connect a small monitoring device or an alarm device.

[0052] In order to limit the left and right shaking of the engineering installation part 3, the vertical holes 244 include two. In order to facilitate the quick alignment of the screws with the vertical holes 244 on the vertical plate 242, the spacing between the two side plates 232 is equal to the width of the vertical plate 242, so as to avoid the vertical plate 242 from being offset in the left and right directions in the U-shaped slot 23, thereby shortening the time for fixing the inverter 6 and improving the installation efficiency of the inverter 6. In order to increase the friction between the clamp ring 1 and the column 7 of the photovoltaic bracket, an anti-slip pad 17 is provided on the inner side of the clamp ring 1.

[0053] The fixing device is designed by using BIM (Building Information Modeling) technology, and its key nodes are optimized in depth for the second time; processing drawings are drawn and customized according to the drawings.

[0054] When the utility model is in use, when the fixing device leaves the factory, it is required that the hoop clamp 1 and the plug-in structure 2 are fixedly connected together. The horizontal plate 241 is connected to the clamp 12 through the horizontal bolt 21. First, the hoop clamp 1 is clamped at the corresponding position of the column 7 of the photovoltaic support. The hoop clamp 1 is fixed on the column 7 of the photovoltaic support by the connecting bolt 11 passing through the two connecting pieces 15 and cooperating with the connecting nut. The engineering installation part 3 is fixed on the plug-in structure 2 by screws, and the inverter 6 is connected to the engineering installation part 3 by using the existing method, so as to achieve the effect of installing the inverter 6 on the column 7 of the photovoltaic support. The steps of installing the horizontal electrical trough box 5 or the vertical electrical trough box 4 are similar and will not be described in detail here.

[0055] The above are only the preferred embodiments of the utility model, and do not impose any limitations on the utility model. Any simple modifications, changes and equivalent structural changes made to the above embodiments according to the technical essence of the utility model still fall within the protection scope of the technical solution of the utility model.
