The utility model provides a pull fence warning line device for oil field production, and relates to the technical field of pull fence warning. The pull fence warning line device for oil field production comprises a plurality of stand columns, a controller and a storage battery, and warning assemblies are fixedly installed at the tops of the stand columns; an inserting groove and a containing groove are fixedly formed in the two sides of the outer surface of the stand column in a penetrating mode respectively, a mechanical coded lock is fixedly installed on one side of the outer surface of the inserting groove, and a locking bar of the mechanical coded lock completely penetrates through the inserting groove and is in sliding connection with the inserting groove; a rotating rod is rotationally embedded in the inner top and the inner bottom of the stand column jointly, and an elastic reset assembly is installed between the rotating rod and the inner wall of the stand column jointly. Through the combination of the foldable supporting rod assembly and the driving hand wheel, stable supporting of rapid unfolding is achieved, and compact folding can be achieved through the storage hole. And by matching with the warning tape which is automatically retracted and released by the volute spiral spring, the technical problems that a traditional device is difficult to carry and a portable device is easy to topple over are solved while the wind resistance is ensured.

This utility model relates to the field of wind and sand control technology, specifically an ecological environment wind and sand control and greening protection device, including a water storage tank and a matching guide bucket cover. The water storage tank has an inner cavity for water storage, with multiple connection holes. A hollow tube is detachably connected to the inner cavity through these connection holes. A water-guiding part is placed on the outer surface of the hollow tube. One end of the water-guiding part passes through the hollow tube and connects to the root system of the planted sapling, while the other end is placed in the water within the inner cavity. The water-guiding part guides the water stored in the inner cavity of the water storage tank to the root system of the planted sapling. This utility model, by employing multiple connection holes and a hollow tube, can selectively protect a number of planted saplings. Simultaneously, the hollow tube ensures the wind resistance of the sapling trunks. Furthermore, the water-guiding part helps the roots maintain sufficient water absorption during the early stages of sapling planting, when their water absorption capacity is poor due to their inability to adapt to sand.

This invention relates to the field of solar energy technology, and particularly to a wind-resistant variable-angle photovoltaic power generation device. It includes a base, a support rod fixedly connected to the base, a support frame rotatably connected to the support rod, a first electric roller rotatably connected to the base, an electric telescopic frame mounted on the base, a solar panel mounted on the support frame, and an electric push rod mounted on the base. The telescopic part of the electric push rod is fixedly connected to a first baffle with a first hole via a fixed frame. A second baffle with a second hole is fixedly connected to the support frame. This invention adjusts the alignment and misalignment of the second hole with the corresponding first hole to change the ventilation and wind-blocking effects of the first and second baffles. When wind impacts the back of the solar panel, it shields the back of the solar panel, ensuring its wind resistance and thus improving the stability of the solar panel.

The utility model discloses a photovoltaic assembly for comprehensive energy power production, which comprises a base and further comprises an adjusting mechanism, the top of the base is provided with the adjusting mechanism, and the adjusting mechanism comprises a rotating shaft A, a photovoltaic panel, a through groove, a rotating shaft B, a supporting rod, a clamping groove A, a clamping groove B, a spring and a limiting rod. One end of the top of the base is provided with a rotating shaft A at a corresponding position and is movably connected with a photovoltaic panel through the rotating shaft A. Under extreme weather conditions such as typhoon days, a limiting rod can be pulled up and reset under the action of a spring to be clamped into a clamping groove A, at the moment, a supporting rod loses limiting, and the supporting rod can be pressed downwards to adjust the angle of the photovoltaic panel. The wind resistance of the photovoltaic panel is reduced, the influence of the external environment on the photovoltaic module is reduced, the operation stability of the power supply end of the comprehensive energy system is ensured, and the damage rate is reduced.
