Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic power station technology and relates to a device for photovoltaic power station inlet. Background Technology

[0002] A photovoltaic power station is a clean energy power generation facility that converts solar energy into electrical energy through solar panels. The operation of such a power station requires connecting the generated direct current lines to a photovoltaic inverter. The inverter's function is to convert the direct current into alternating current so that it can be compatible with the power grid and used for daily purposes.

[0003] In existing technology, inverters are equipped with female connectors for connection to male wires. Multiple male-connected wires are threaded through a stainless steel corrugated conduit for protection. However, an uncovered space exists between the corrugated conduit and the male connectors, exposing the wires in this area. Furthermore, the upper end of the corrugated conduit is suspended, which, over time, may lead to wire damage or loosening of the male connectors. Therefore, designing a device for photovoltaic power plant inlets is essential. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a device for the connection point of a photovoltaic power station.

[0005] The objective of this utility model can be achieved through the following technical solution: A device for the connection point of a photovoltaic power station, the photovoltaic power station including an inverter, the inverter having multiple sets of female connectors at its bottom, the female connectors being detachably connected to male connectors with wires, characterized in that the device includes a crossbar and a protective sleeve, the end of the crossbar being connected to the inverter via a connecting piece, and the crossbar being arranged below the inverter, multiple adjusting seats being slidably connected to the crossbar, each adjusting seat being threaded with a screw, the adjusting seat being connected to a C-type clamp, the protective sleeve being detachably connected to the C-type clamp, the protective sleeve including a middle pipe section, an upper pipe section connected to the upper part of the middle pipe section, and a lower positioning ring connected to the lower part of the middle pipe section, the upper pipe section being larger than the middle pipe section, the middle pipe section also having multiple limiting rings, and the lower positioning ring also having a screw.

[0006] The C-shaped clip has a fixing lug in the middle and an elastic protrusion at the end.

[0007] The protective sleeve is made by one-piece injection molding.

[0008] The screw is a hand-tightening component.

[0009] Compared with existing technologies, this device for photovoltaic power plant inlets has the following advantages:

[0010] In this invention, the protective sleeve can cover the exposed wire between the male connector and the stainless steel corrugated pipe, while the lower positioning ring ensures that the upper end of the stainless steel corrugated pipe is fixed. This design significantly extends the service life of the connection point and enhances the stability of use. Attached Figure Description

[0016] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0017] like Figures 1-4 As shown, this device is used for the connection of a photovoltaic power station. The photovoltaic power station includes an inverter 1. In this embodiment, the inverter 1 is a conventional product. The bottom of the inverter 1 has multiple sets of female connectors 6, which are detachably connected to male connectors 7 with wires. In this embodiment, the connection method between the female connectors 6 and the male connectors 7 adopts conventional technology. The device includes a crossbar 5 and a protective sleeve 9. The protective sleeve 9 is integrally injection molded using conventional technology. The end of the crossbar 5 is connected to the inverter 1 through a connecting piece 2, and the crossbar 5 is arranged below the inverter 1. Multiple adjusting seats 4 are slidably connected to the crossbar 5. The adjusting seat 4 is threaded with screw 10, which is a hand-tightening screw. The adjusting seat 4 is connected to the C-type clamp 8. The protective sleeve 9 is detachably connected to the C-type clamp 8. The protective sleeve 9 includes an intermediate pipe section 9b, an upper pipe section 9a connected to the upper part of the intermediate pipe section 9b, and a lower positioning ring 9c connected to the lower part of the intermediate pipe section 9b. The size of the upper pipe section 9a is larger than that of the intermediate pipe section 9b. The intermediate pipe section 9b also has multiple retaining rings 9b1. The lower positioning ring 9c also has screw 11, which fixes the stainless steel corrugated pipe 3 that is clamped in the lower positioning ring 9c.

[0018] The C-type clip 8 has a fixing lug 8a in the middle and an elastic protrusion 8b at the end.

[0019] In this invention, the protective sleeve 9 can cover the exposed wire between the male connector 7 and the stainless steel corrugated pipe 3, while the lower positioning ring 9c ensures that the upper end of the stainless steel corrugated pipe 3 is fixed. This design significantly extends the service life of the connection point and enhances the stability of use.
