Description

Technical Field

[0001] The utility model relates to the technical field of safety warning for electric power engineering, in particular to a safety warning device for electric power engineering. Background Art

[0002] Power engineering refers to engineering related to the production, transmission and distribution of electric energy. In a broad sense, it also includes engineering that uses electricity as power and energy in various fields. It can be understood as power transmission and transformation engineering. During power construction, safety warning devices need to be placed at the construction site to warn people around and prevent other people from entering the working environment and causing electric shock accidents.

[0003] Publication number "CN217974134U" provides a safety warning device for power engineering. By setting a warning sign, a bracket, a first spring and a locking groove, multiple limit blocks drive the sliding block to squeeze the first spring through the connecting block. At the same time, the limit block is tightly fitted with the support rod, and the elastic frame squeezes the locking block on one side of the pad into the locking groove. Multiple locking blocks can support the support rod, which solves the problem that the existing equipment cannot conveniently adjust the height of the sign, which easily leads to a single height of the sign, is not convenient for use in different environments, and reduces the practicality of the sign for safety warnings.

[0004] However, the above technical solutions and the prior art have the following defects:

[0005] Although the safety warning device for electric power engineering can adjust the height of the signboard, the adjustment structure requires two workers to squeeze the locking blocks on the left and right sides at the same time to adjust the height during the actual adjustment process. The convenience of adjustment needs to be improved. In addition, the bottom of the safety warning device for electric power engineering is only supported by the base. Once windy weather occurs, the warning sign will easily shake back and forth and fall over. The stability of use needs to be improved. Utility Model Content

The second turntable 541 facilitates the staff to rotate the positioning support rod 54 by hand.

[0036] Working principle: During the construction of power engineering, the staff first pushes the device to the required position on the construction site (locks the universal wheel 41 with foot brake after pushing it to the required position) so that the safety warning sign 1 can serve as a safety warning to the surrounding idlers. When it is necessary to adjust the height of the safety warning sign 1, the staff only needs to rotate the first turntable 242 forward by hand, so that the first turntable 242 can drive the extended worm 24 to rotate forward together, and the forward rotating extended worm 24 will drive the transmission worm gears 25 on the left and right sides to reverse synchronously, so that the transmission worm gears 25 on the left and right sides drive the two sets of vertical screws 26 to reverse synchronously, thereby causing the connecting seat 22 to drive the support plate 3 to move upward, and the safety warning sign 1 will rise together with the support plate 3. Similarly, when the staff rotates the extended worm 24 When reversing, the support plate 3 will drive the safety warning sign 1 to move downward, so that the staff can adjust the height of the safety warning sign 1 to the required height according to the needs of the construction site; when the height adjustment of the safety warning sign 1 is completed, the staff first loosens the locking screws 52 on the front and rear sides respectively, and then can respectively pull the extension plates 53 on the front and rear sides to extend them, and when the extension plates 53 on the front and rear sides extend to the required length, the locking screws 52 on the front and rear sides can be tightened again to fix the extension plates 53, and then the front and rear positioning support rods 54 on the front and rear sides are respectively rotated forward by the second turntable 541, so that the positioning support rods 54 move downward and contact the external ground, so that the positioning support rods 54 can assist in supporting the bottom base 4 through the extension plates 53 and the limiting shell 51 (refer to Figure 2), thereby further increasing the longitudinal support stability of the base 4 and preventing the raised safety warning sign 1 from easily shaking back and forth in windy weather; when the device needs to be moved, the staff first reverses the positioning support rods 54 on the front and rear sides to move them upward, then loosens the locking screws 52 and pushes and retracts the extension plates 53 on the front and rear sides inward to prevent the extended extension plates 53 from reducing the transfer convenience of the base 4. At this time, the universal wheel 41 with foot brake can be unlocked to transfer the device.
