Description

Technical Field

[0001] This utility model relates to the field of safety protection in building engineering, and in particular to a safety protection device for building engineering. Background Art

[0002] Building construction is a part of construction projects, referring to the engineering entities formed through the construction of various types of buildings and their ancillary facilities, as well as the installation of supporting lines, pipelines, and equipment. Building construction includes factories, theaters, hotels, shops, schools, hospitals, and residences, etc., to meet people's needs for production, living, learning, and public activities.

[0003] Safety protection devices are needed to isolate construction areas during construction projects to reduce cross-contamination between personnel inside and outside the site and lower the risk of accidents. However, current safety protection devices mostly use guardrails or protective panels, which are complex to install and dismantle, inconvenient to store later, and take up a lot of storage space. Therefore, we propose a safety protection device for construction projects to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a safety protection device for construction projects to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A safety protection device for construction engineering includes a protective housing. Two infrared sensors are fixedly installed on the front of the protective housing. The housing has two cavities inside, and two bearings are fixedly embedded in the inner wall of each cavity. A rotating shaft is fixedly installed on the inner ring of each set of bearings. Two drive motors are fixedly installed on the upper surface of the protective housing. The top end of each rotating shaft is connected to the output end of the drive motor. A set of protective strips is wrapped around the outer surface of each rotating shaft. The ends of the two sets of protective strips that are far apart from each other penetrate the protective housing and are fixedly connected to a connecting plate. A support base is fixedly connected to the bottom end of each connecting plate. A warning light strip is fixedly connected to the front of each protective strip. A handle is fixedly connected to the side of the two connecting plates that are far apart from each other. A connecting strap is fixedly connected between the two sets of protective strips.

[0007] In a further embodiment, the upper surface of the protective housing is fitted with a cover by screws, and the cover has ventilation windows on both the left and right sides.

[0008] In a further embodiment, a control switch and an alarm are installed on the front of the hood.

[0009] In a further embodiment, a back cover is screwed onto the back of the protective housing, and a controller is mounted on the back of the back cover.

[0010] In a further embodiment, a warning sign is fixedly connected to the front of the protective housing, and a reflective strip is fixedly connected to the front of each connecting plate.

[0011] In a further embodiment, two sets of movable wheels are fixedly installed on the bottom surface of the protective housing, and a fixing hole is opened on the upper surface of each support base, with a ground nail inside each fixing hole.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] This device features two cavities within a protective housing, each containing a rotatable shaft. Protective tape is wound around the shaft, and pulling the handle on the connecting plate activates a drive motor that rotates the shaft, allowing the protective tape to be unfolded to a specific width. This allows for adjustment based on the protected area, enabling rapid installation and deployment of the protective device. Warning lights are integrated into the protective tape, providing effective safety warnings at night. Infrared sensors detect movement on both sides; if someone approaches, the controller activates an alarm, further enhancing safety. After use, the drive motor rotates the shaft to quickly rewind the protective tape, facilitating disassembly and storage of the device. Attached Figure Description
