[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0031] Embodiment 1

[0032] Please refer to Figures 1 to 10 , a safety construction protection device, including a protection frame and protection railings. A plurality of protection railings are fixedly connected to the inner wall surface of the protection frame at equal intervals. Two sliders are slidably sleeved on the surfaces of two of the protection railings. A warning board is fixedly connected to the surface of the slider. A screw sleeve is fixedly connected to the surface of the warning board close to the slider. A first screw rod is rotatably connected to the inner wall surface of the protection frame. The screw sleeve is threadedly sleeved on the surface of the first screw rod. A first bevel gear is fixedly sleeved on the surface of the first screw rod. An installation frame is fixedly connected to the inner wall surface of the protection frame outside the first bevel gear. A first rotating rod is rotatably connected to the surface of the installation frame. One end of the first rotating rod penetrates through the surface of the installation frame and extends into the interior of the installation frame, and is fixedly connected to a second bevel gear arranged inside the installation frame. The second bevel gear is meshed with the first bevel gear.

[0033] A hand wheel is fixedly connected to the end of the first rotating rod away from the second bevel gear. A limit bolt is threadedly connected to the surface of the hand wheel.

[0034] An L-shaped plate is fixedly connected to the upper surface of the warning board. A bidirectional screw rod is rotatably connected to the inner wall surface of the L-shaped plate at a position above the warning board. Strip-shaped moving plates are symmetrically threadedly sleeved on the surface of the bidirectional screw rod. A cleaning brush is fixedly connected to the surface of the strip-shaped moving plate close to the warning board.

[0035] One end of the bidirectional screw rod penetrates through one side surface of the L-shaped plate and extends outside the L-shaped plate, and is fixedly connected to a gear arranged outside the L-shaped plate. A rack is fixedly connected to the inner wall surface of the protection frame. The gear is meshed with the rack.

[0036] A limit block is fixedly connected to the surface of the strip-shaped moving plate. The limit block is inserted into the inner surface of the L-shaped plate and is slidably connected to the L-shaped plate.

[0037] Reflective strips are arranged on the surface of the warning board. When the strip-shaped moving plate is at any position on the surface of the warning board, it will not affect the warning effect of the reflective strips.

[0038] Working principle of this embodiment: When using this kind of protective device, first splice the protective device, and then fix the protective device to a suitable position near the construction surface through the mounting base plate with fixing bolts. Then, according to the construction environment, adjust the height of the warning board. When adjusting, first loosen the limit bolt to release the limit on the handwheel, and then rotate the handwheel. The rotation of the handwheel drives the first rotating rod to rotate, the rotation of the first rotating rod drives the second bevel gear to rotate, the rotation of the second bevel gear drives the first bevel gear to rotate, the rotation of the first bevel gear drives the first screw rod to rotate, and the rotation of the first screw rod enables the nut sleeve to move on the surface of the first screw rod, so as to drive the warning board to move under the limit of the slider, and then the installation height of the warning board can be adjusted according to different construction environments.

[0039] During this process, the movement of the warning board can drive the L-shaped plate to move accordingly. The movement of the L-shaped plate can drive the gear to rotate on the surface of the rack. The rotation of the gear can drive the bidirectional screw rod to rotate. The rotation of the bidirectional screw rod can drive the strip-shaped moving plates on both sides to approach and move away from each other. The movement of the strip-shaped moving plates can drive the cleaning brush hairs to move on the surface of the warning board, so as to clean the dust attached to the surface of the warning board. With such a design, when cleaning the warning board, the movement of the warning board can also be controlled, and then the cleaning brush hairs can clean a larger range, avoiding the dust from blocking the reflective strips, and the strip-shaped moving plates will not affect the warning effect of the reflective strips at any position on the surface of the warning board. After the cleaning is completed, adjust the position of the warning board again.

[0040] By setting the warning board, it can remind the vehicles passing by at night through the reflective strips on the surface of the warning board, avoid traffic accidents during night construction, and improve the protection performance of the protective device.

[0041] Embodiment Two

[0042] This embodiment is an improvement made on the basis of Embodiment One. Specifically, please refer to Figures 1 to 10 , columns are symmetrically arranged on both sides of the protective frame. The bottom surface of each column is fixedly connected with a mounting base plate. U-shaped plates are symmetrically and fixedly connected to the surface of the column. The inner wall surface of the U-shaped plate is fixedly connected with a second screw rod through a first nut. Two mounting blocks are slidably sleeved on the surface of the second screw rod. Adjusting nuts are threadedly sleeved on both sides of each mounting block on the surface of the second screw rod. L-shaped insertion rods are symmetrically and fixedly connected to the surface of the protective frame. The L-shaped insertion rods are inserted into the insertion holes opened on the surface of the mounting blocks.

[0043] Working principle of this embodiment: When multiple protective frames need to be spliced, first adjust the position of the mounting block according to the height position of the L-shaped insertion rod on the surface of the protective frame. During adjustment, loosen the adjusting nuts on both sides of the mounting block, and then move the mounting block so that the L-shaped insertion rod can just be inserted into the mounting block. At this time, tighten the two adjusting nuts to limit the position of the mounting block. Then, the protective frame can be spliced with the adjacent upright column through the L-shaped insertion rod. This splicing method does not require fixing with bolts, is relatively convenient to disassemble later, and will not be misaligned during splicing, improving the splicing quality.
