The embodiment of the utility model provides a pressing block, a connecting piece, a pressing block assembly and a photovoltaic system. Wherein the photovoltaic system comprises C-shaped steel, a connecting piece and a photovoltaic frame; the C-shaped steel forms a strip-shaped opening, and the connecting piece is located in the strip-shaped opening and hooks the two side edges of the C-shaped steel. The photovoltaic frame is erected on the strip-shaped opening and comprises a convex edge; the pressing block comprises a pressing block body, the pressing block body comprises a first surface, the two opposite ends of the pressing block body respectively form hooked edges protruding out of the first surface, and the hooked edges are arranged on the convex edges in a pressing mode; the pressing block is connected with the connecting piece in a fastening mode so as to fasten the photovoltaic frame and the C-shaped steel. According to the embodiment of the invention, the pressing block is pressed on the convex edges of the two adjacent photovoltaic frames, the pressing block and the connecting piece are fastened through the fastening piece, the photovoltaic frames and the C-shaped steel are fastened, the hooked edges of the pressing block are pressed on the convex edges of the photovoltaic frames, and the acting force between the hooked edges and the convex edges acts on the same line instead of the same point. And the fixed photovoltaic frame has relatively high load resistance.

The utility model discloses an overhead transmission line steel pipe pole structure with a top sealing plate with a line hanging function, which comprises a pole body, a plurality of cross arm structures are symmetrically arranged on the pole body, a ladder stand is arranged on the pole body, and an anti-climbing device is arranged at the bottom of the ladder stand. Compared with the prior art, the utility model has the advantages that the structure is simple, and the use is convenient; wire hanging is integrated, wire hanging holes are directly formed in the top sealing plate, the welding procedure is omitted, cost is reduced, and reliability is improved; the anti-load capacity is high, the variable cross-section rod body and the flange base are designed, and through experimental verification, 34.329 kN transverse wind load and 25.186 kN longitudinal wire tension can be borne; the cross arm and the pole body are in modular connection, and the crawling ladder is inserted and mounted, so that the field operation time is shortened; the safety is high, and the service life is prolonged due to dual protection of climbing thorn prevention and a hot-dip galvanizing process.

This utility model discloses a glass fiber reinforced continuously wound spiral rib pipe for tunnel lining. The pipe and the spiral rib layer continuously wound on the pipe are provided with an interface layer on the surface of the pipe and the spiral rib layer. The pipe includes an inner lining layer and a structural layer. A grid layer is laid on the surface of the structural layer. All layers are connected as one. The pipe of this utility model includes an inner lining layer and a structural layer. By adding continuously wound spiral ribs, a grid layer and an interface layer to the outer surface of the pipe, a spiral rib pipe can be used in tunnels. It has a reasonable manufacturing cost and strong load-bearing capacity.
