Description

Technical Field

[0001] This utility model belongs to the field of construction safety warning and relates to a construction safety warning device. Background Technology

[0002] Warning signs are used to provide effective information to people. They are necessary when repairing urban pipe networks to alert drivers and pedestrians and reduce unnecessary traffic accidents. Currently, the existing warning method for sewer construction or maintenance involves safety cones placed around the manhole opening. However, due to natural wind and the wind generated by passing vehicles, these cones are easily displaced, rendering the warning ineffective. Furthermore, this method is ineffective at night, failing to attract the attention of pedestrians or vehicles, increasing the risk of pedestrians falling into the sewers and causing danger.

[0003] Therefore, this utility model provides a construction safety warning device to solve the above problems. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model discloses a construction safety warning device. The technical solution adopted is as follows: a rectangular base frame is provided, and the upper surfaces of the four sides of the rectangular base frame are grooved and embedded with first warning light strips. U-shaped brackets are fixedly connected to the upper middle positions of the left and right sides of the rectangular base frame. A fixing column is installed in the middle of the top of the U-shaped bracket. The top of the fixing column is fixedly connected to the bottom of the circular warning sign. Screw holes are respectively opened in the lower part of the left and right side walls of the U-shaped bracket. Fixing components are symmetrically inserted into the left and right screw holes. The fixing components include adjusting screws. Limiting rings are respectively set at the opposite ends of the left and right adjusting screws. Connecting rods are movably mounted on the side of the limiting rings near the threads. Anti-slip nails are fixedly set on the lower outward side of the connecting rods. Photovoltaic panels are respectively installed on the left and right sides of the upper crossbeam of the U-shaped bracket.

[0005] In a preferred embodiment of this utility model, the left and right sides of the rear inner wall of the rectangular base frame are fixedly connected to the two ends of the U-shaped connecting rod, and the two ends of the U-shaped connecting rod are hinged to the two rear ends of the fall protection net. The upper part of the front edge of the fall protection net is fixedly connected to a locking block with an insertion hole at the front end. A pin is inserted into the opening at the front end of the locking block, and the bottom of the pin is fixedly connected to the upper part of the front edge of the rectangular base frame. By using a fall protection net that can rotate and open around the U-shaped connecting rod, it is convenient to block the fall protection net at the manhole opening when repairing the sewer, so as to prevent pedestrians from falling into it and causing danger. At the same time, it is also convenient for maintenance personnel to open and close the fall protection net independently.

[0006] As a preferred embodiment of this utility model, a second warning light strip is installed on the front and rear side walls of the U-shaped bracket; by using the second warning light strip, it is convenient to make the spatial height of the U-shaped bracket conspicuously marked, so as to prevent pedestrians or vehicles from hitting the U-shaped bracket at night, and further improve the safety warning effect.

[0007] As a preferred embodiment of this utility model, reflective strips are respectively provided on the front and rear circumferential edges of the circular warning sign.

[0008] As a preferred embodiment of this utility model, the length between the left and right inner walls and the front and rear inner walls of the rectangular base frame is greater than the diameter of the sewer manhole cover; this design makes it easy to place the device at the sewer manhole that needs maintenance, avoiding obstruction of maintenance personnel from entering and exiting the manhole.

[0009] As a preferred embodiment of this utility model, a micro controller is installed on the right side of the lower side wall of the upper crossbeam of the U-shaped bracket; by using a micro controller, it is easy to control the first warning light strip and the second warning light strip, which will automatically light up at night and automatically turn off during the day, thereby improving the effect of nighttime safety warning and achieving the purpose of energy saving.

[0010] The beneficial effects of this utility model are as follows: By setting a rectangular base frame and a first warning light strip on the upper side of the rectangular base frame, and at the same time, setting a rotatable and closable anti-fall net inside the rectangular base frame, the location of the manhole can be clearly indicated at night, and pedestrians can be prevented from falling into the manhole, which can effectively improve the warning effect of the device at night; at the same time, fixing components are set on the left and right sides of the U-shaped bracket, which can lock the device in place at the manhole by connecting rods on the left and right sides and anti-slip nails, preventing the device from moving, and further improving the safety of the sewer manhole during construction or maintenance.
