Description

Technical Field

[0001] The utility model relates to the technical field of protective equipment, in particular to a protective fence based on on-site construction operations. Background Art

[0002] Safety is the most important aspect in construction. At present, the safety control of construction sites is very strict. Guardrails are necessary. Guardrails are mainly used in areas such as foundation pits, distribution boxes, steel bars, elevator shafts, etc., and are one of the protective safety measures on the construction site.

[0003] The existing guardrails are short iron fences. When protecting the construction site, non-construction workers can easily cross the guardrails without supervision, and the protection effect is poor. At the same time, in order to warn non-construction workers not to approach, the existing guardrails use reflective light strips to warn non-construction workers. However, the light strips require power cords to be pulled. The power cords are exposed on the construction site and are easily crushed and caught by construction vehicles, causing the power cords to break and leak electricity, posing a safety risk of electric shock.

[0010] Preferably, the bottom of the servo motor is fixedly connected to the upper surface of the bearing plate, and the power output end of the servo motor is fixedly connected to one end of the active bevel gear.

[0011] Compared with the related art, the guardrail based on on-site construction provided by the utility model has the following beneficial effects:

[0012] By providing a base plate, a sleeve, a telescopic tube, a top plate and a lifting structure, the stabilizing plates inside the mounting grooves at both ends of the base plate are rotated to the outside of the mounting grooves at both ends of the base plate through connecting rods, and the stabilizing plates are connected and fixed to the ground with pins to prevent the base plate from moving. If protection is required on all four sides at the same time, multiple groups of base plates can be surrounded in a circle, and the operator simultaneously starts two groups of servo synchronous motors. The rotation of the power output end of the servo synchronous motor drives the threaded rod to rotate. When the threaded rod rotates, it is threadedly connected with the threaded hole on the upper surface of the lifting plate. Since the lifting plate is fixedly connected to the lower end of the telescopic tube, the lifting plate pushes the telescopic tube to rise, so that the telescopic tube rises along the sleeve, which pushes the top plate to rise, thereby increasing the protection height, preventing ordinary guardrails from being too low, and preventing non-construction personnel from climbing over, thereby effectively improving the protection effect.

[0013] By providing columns, solar panels, adjustment structures, solar tracking sensors, batteries and single-chip microcomputers, the solar panels receive sunlight to generate electricity and store the electrical energy inside the batteries. The batteries provide power for the servo synchronous motor, servo motor, single-chip microcomputer, solar tracking sensors, alarm lights and monitoring probes. When the alarm light is turned on, the alarm light continues to flash to provide a continuous warning, while the monitoring probe can provide real-time monitoring. When the solar panel cannot maintain the best irradiation angle with the sunlight, the solar tracking sensor measures the direction of the sun and sends the measured data signal to the single-chip microcomputer. The single-chip microcomputer controls the servo motor to start. The rotation of the power output end of the servo motor drives the active bevel gear to rotate. When the active bevel gear rotates, it engages the driven bevel gear to rotate. When the driven bevel gear rotates, it drives the rotating rod to rotate. When the rotating rod rotates, it drives the connecting plate to rotate, thereby driving the solar panel to intelligently change the angle of receiving sunlight, receive sunlight at the best angle to maintain power generation, continuously charge the battery, avoid the pulling of the power cord, and effectively avoid the safety risk of electric shock caused by leakage due to power cord breakage.
