Description

Technical Field

[0001] The utility model relates to the technical field of electric power devices, and more specifically to an electric power tower installation device. Background Art

[0002] As we all know, clean energy like solar energy has the advantage of being inexhaustible, but it also has serious disadvantages. The high cost of power generation will gradually improve with the advancement of technology and its wide application, but its unstable natural law cannot be changed. For example, solar power generation becomes unstable with the change of light intensity, and most power loads require stable power supply, which seriously hinders its direct application. The existing technical method is to store solar power in a storage battery, and then the storage battery is converted into electricity through an inverter and then connected to the power grid or supplied to the power load. In the process of solar power generation, the photovoltaic panels used for power generation need to be fixed on the power tower.

[0003] However, the existing steel pipe mounting frame for the iron tower has the following shortcomings: 1. It adopts a simple clamping piece to directly clamp and fix, and the fixing effect is poor; 2. It is impossible to adjust the spacing between the fixing pieces according to the actual size of the photovoltaic panel. The existing patent is a new energy power iron tower steel pipe mounting frame, and the patent authorization number is CN 209453440 U. The bearing plate, the slide groove, the fixing piece, the lower clamp plate, the upper clamp plate, the fixing sleeve and the fixing seat are set. The bearing plate fixes the photovoltaic panel on the iron tower. The structure is simple and fixed, and the operation is convenient. The fixing effect is good and it is convenient to install and remove the photovoltaic panel. The slider at the bottom of the fixing piece slides on the slide groove surface of the bearing plate, and the spacing between the fixing pieces can be arbitrarily adjusted. It is convenient to adjust the spacing between the fixing pieces according to the size of the photovoltaic panel, thereby facilitating the fixing of photovoltaic panels of different sizes.

[0004] However, in the patent authorization number CN 209453440 U, ​​the fixing sleeve is first placed on the steel pipe position of the iron tower at the installation position, and then the bolt connection seat on the fixing sleeve is connected together by a second fixing bolt to fix the fixing sleeve at this position. Since it needs to be installed at a high place of the iron tower, it also needs to be clamped and locked with bolts, which is very inconvenient to operate. In order to facilitate the installation and fixation of the cross arm, we have proposed a power tower installation device to solve the above-mentioned problems. Utility Model Content

When the first clamping block and the second clamping block are misaligned, their inclined surfaces fit each other, and the swing arm is limited by the stop block, so that the installation of the cross arm can be completed quickly, and the operation is very convenient.
