Description

Technical Field

[0001] This utility model relates to the field of lightning protection pole technology, specifically to a lightning protection pole for photovoltaic power stations. Background Technology

[0002] A lightning protection tower is a common type of iron tower-shaped lightning protection device. It is also known as a lightning rod tower, steel structure lightning rod, or tower-type lightning rod. There are four specifications of lightning protection towers: GFL four-column angle steel lightning protection tower; GJT three-column round steel lightning protection tower; GH steel pipe pole lightning protection tower; and GFW lightning protection line tower.

[0003] A search revealed an existing patent (CN205489418U) disclosing a lightning protection tower for a photovoltaic power station, comprising a first column, a second column, and a third column. The tops of the first and second columns have threaded holes, and the bottoms of the second and third columns are fixedly connected to lead screws that mate with the threaded holes. The second and third columns have grooves on both sides, and handles are hinged within these grooves via rotating shafts. Magnets are embedded in the edges of the handles. All three columns are made of metal. The height of the first column is greater than that of the second column, and the height of the second column is greater than that of the third column. This invention has the following advantages: it is convenient to transport and easy to install.

[0004] However, while the above solution achieves detachability through threads, its connection structure is not stable enough and is prone to loosening under lightning and outdoor weather conditions, resulting in an insufficiently secure connection.

[0005] In view of this, this utility model proposes a lightning protection rod for photovoltaic power stations. Utility Model Content

[0006] This utility model proposes a lightning protection rod for photovoltaic power stations, which solves the problem that related technologies achieve detachability through threads, but the connection structure is not stable enough and is prone to loosening under lightning and outdoor weather conditions, resulting in an insufficiently secure connection.

[0007] The technical solution of this utility model is as follows: A lightning protection pole for a photovoltaic power station includes a base; a plug-in seat is fixedly connected to the top of the base; a pole body one is plugged into the plug-in seat; a slot is provided on the top edge of the pole body one; a plug-in rod is plugged into the slot; a ball bearing is provided on the side of the plug-in rod facing the center of the pole body one; the ball bearing fits against the pole body one; a pole body two is fixedly connected to the top of the plug-in rod; the bottom of the pole body two fits against the top of the pole body one; a pull ring one is fixedly connected to the outside of the pole body one; a connecting bottom rod is plugged into the side of the base; and the connecting bottom rod contains... An alarm box is installed at the bottom, with a button fixedly connected to the bottom of the alarm box. A fixing block is fixedly connected to the other end of the connecting rod. A pull rope mechanism is provided between the top of the fixing block and the first rod. After the plug rod is inserted into the slot, the ball bearing on one side of the plug rod rolls against the inner wall of the slot, which can reduce the friction generated by the plug rod during vibration and prevent the second rod from shaking and falling off the top of the first rod. At the same time, the pull rope mechanism fixes the first rod vertically. The button at the bottom of the alarm box is in contact with the ground. An alarm can be triggered when the device tilt button is not pressed, thus protecting the stability of the lightning protection rod.

The spherical grounding block can support the bottom of the base and reduce water accumulation at the bottom of the base.

[0015] The beneficial effects of this utility model are as follows:

[0016] In this utility model, after the insertion rod is inserted into the slot, the ball bearing on one side of the insertion rod rolls against the inner wall of the slot, which can reduce the friction generated by the insertion rod during vibration and prevent the second rod from shaking and falling off the top of the first rod. At the same time, the first rod is vertically fixed by the rope mechanism. The button at the bottom of the alarm box is in contact with the ground. When the device tilt button is not pressed, an alarm can be generated, thus protecting the stability of the lightning protection rod.

[0017] In this utility model, the first and second magnets can fix the base and the connecting rod, and the connecting rod can increase the support position of the base, thereby maintaining the overall stability of the equipment. The second and first pull rings on both sides can be fixed by the rope, which can pull the whole equipment and achieve the stability of the equipment after it is fixed.

[0018] In this invention, the pull ring 1, rope and pull ring 2 can generate tension on the base from multiple directions to strengthen the overall stability of the base. The insulating sleeve can prevent the alarm box and button from being affected by lightning. The spherical grounding block can support the bottom of the base and reduce water accumulation at the bottom of the base. Attached Figure Description
