BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 It is a structural diagram of an installation structure for an anti-islanding protection device shown in the utility model;

[0015] Figure 2 for Figure 1 The structural diagram of the lifting and lowering regulator is shown in . DETAILED DESCRIPTION

[0016] The present invention is described in detail below in conjunction with the various embodiments shown in the accompanying drawings, but it should be noted that these embodiments are not limitations of the present invention, and any equivalent transformations or substitutions in functions, methods, or structures made by ordinary technicians in the field based on these embodiments are all within the scope of protection of the present invention.

[0017] like Figure 1 and 2 The installation structure for an anti-islanding protection device shown in the figure comprises two threaded columns 3 and two clamping mechanisms symmetrically arranged with a horizontal line as the axis of symmetry. The threaded columns 3 are provided with mounting plates 4 at the upper and lower ends, and the mounting plates 4 are provided with mounting holes 41, so as to facilitate installation in a photovoltaic cabinet.

[0018] The clamping mechanism includes a clamping plate 2 and a lifting regulator 5 connected to both ends of the clamping plate 2. The anti-islanding protection device 1 is clamped by the upper and lower clamping plates 2, and is firmly fixed. The anti-islanding protection device 1 is suspended, and the clamping plate 2 is provided with heat dissipation holes (not shown), which has a good heat dissipation effect.

[0019] The clamping plate 2 includes a bottom plate 21 and side plates 22 connected to both ends of the bottom plate 21. The bottom plate 21 is bonded with a rubber pad 23, which is relatively soft and fits the anti-islanding protection device 1 to protect it, and also increases the friction force, further improving the stability of the clamping plate 2 on the anti-islanding protection device 1.

[0020] The lifting regulator 5 comprises a threaded sleeve 51, a first cylinder 54 and a second cylinder 53 connected thereto, and a cylinder cover 52. The threaded sleeve 51 is screwed onto the threaded column 3, and the height of the lifting regulator 5 can be adjusted by rotating the threaded sleeve 51, and the position of the clamping plate 2 can be adjusted, and then the position of the anti-islanding protection device 1 can be flexibly adjusted, so that the anti-islanding protection device 1 can be adjusted to a suitable position for connection with the photovoltaic grid-connected system.

[0021] The first cylinder 54 and the second cylinder 53 are sleeved on the threaded column 3 and are raised and lowered synchronously with the threaded sleeve 51. The side plate 22 is connected to the first cylinder 54, so that the clamping plate 2 and the threaded sleeve 51 are raised and lowered synchronously. The diameter of the second cylinder 53 is larger than that of the first cylinder 54, and the first cylinder 54 and the second cylinder 53 are connected by a connecting portion 57. The first cylinder 54 and the second cylinder 53 are coaxially arranged.

[0022] The bottom of the threaded sleeve 51 is provided with an annular plate 55 extending outward, and the top and bottom surfaces of the annular plate 55 are both installed with universal balls 56. The annular plate 55 and the universal balls 56 are both located in the second cylinder 53, and the cylinder cover 52 is sleeved on the threaded sleeve 51. The cylinder cover 52 is connected to the second cylinder 53 to restrict the annular plate 55 and the universal balls 56 in the second cylinder 53. Specifically, the cylinder cover 52 is screwed on the second cylinder 53. The first cylinder 54, the second cylinder 53, the clamping plate 2, and the threaded sleeve 51 are lifted and lowered synchronously.

[0023] The universal ball 56 on the top surface of the annular plate 55 abuts against the cylinder cover 52, and the universal ball 56 on the bottom surface of the annular plate 55 abuts against the connecting portion 57 of the first cylinder 54 and the second cylinder 53. When the threaded sleeve 51 rotates on the threaded column 3, the universal ball 56 rotates on the cylinder cover 52 and the connecting portion 57, reducing friction. The universal ball 56 is coated with lubricating oil, which further reduces friction.

[0024] During installation, the height of the lower clamping plate 2 is adjusted by the lifting regulator 5 according to the position where the anti-islanding protective device 1 needs to be fixed, and then the anti-islanding protective device 1 is placed on the lower clamping plate 2, and then the position of the upper clamping plate 2 is adjusted by the lifting regulator 5 to press and hold the anti-islanding protective device 1; during disassembly, the upper clamping plate 2 is raised by the lifting regulator 5 to leave the anti-islanding protective device 1, and then the anti-islanding protective device 1 can be taken out, and the disassembly and assembly operations are convenient and quick.

[0025] The series of detailed descriptions listed above are only specific descriptions of feasible implementation methods of the utility model. They are not intended to limit the protection scope of the utility model. Any equivalent implementation methods or changes that do not deviate from the technical spirit of the utility model should be included in the protection scope of the utility model.

[0026] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
