Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of offshore oil drilling platform, especially a composite guardrail device. BACKGROUND

[0002] The guardrail for offshore oil drilling platform must have high corrosion resistance, fire resistance and safety performance, and is generally made of steel structural members and composite materials. Since the steel structural member guardrail is heavy in weight, it not only increases the weight of the oil drilling platform, but also is prone to rust due to long-term exposure to marine air. Therefore, a large amount of funds is needed for maintenance every year, which causes damage to the maintenance personnel's body and damages the environment. Therefore, the steel structural member guardrail is gradually replaced by the composite material structural member guardrail. At present, the composite material guardrail used solves the problem of heavy weight of the guardrail, but has poor adjustability.

[0003] The Chinese patent with publication number CN213087328U discloses a composite guardrail for offshore oil drilling platform, which comprises a guardrail upright, a guardrail crossbar, a kick plate, a connecting piece, a base, a reinforcing pipe and a handrail. The lower end of the guardrail upright is fixed in the base. The connecting piece comprises an open circular pipe, a right-angle connecting piece and a multidirectional connecting piece. The kick plate is fixed to the lower end of the guardrail crossbar. The inner cavity bottom of the guardrail upright is provided with a reinforcing pipe. The uppermost guardrail crossbar is provided with a handrail. The guardrail upright and the guardrail crossbar are fixedly connected through the connecting piece. The guardrail crossbars between the adjacent two guardrails at the corner are fixedly connected through the right-angle connecting piece or the multidirectional connecting piece. The above-mentioned device cannot set the guardrail upright at the corner, and the right-angle connecting piece and the multidirectional connecting piece are formed by molding process. As known, the raw material of the molded product is composed of randomly distributed short fibers and resin, and the fiber content is low, which leads to poor strength of the molded product. When the corner of the guardrail is subjected to instantaneous impact force, it is easily damaged, and the overall guardrail has poor impact resistance. In view of this, in order to prevent safety hazards, the corner of the composite guardrail is generally set as a no-material-stacking and pedestrian-stopping area on the offshore oil drilling platform, which wastes a large amount of limited space of the offshore drilling platform. Therefore, it is urgent for the technical personnel in the field to solve the above-mentioned problems. UTILITY MODEL CONTENTS
