Description

Technical Field

[0001] This utility model relates to the field of water conservancy construction technology, specifically a safety protection structure for water conservancy construction. Background Technology

[0002] Water conservancy project construction is a type of engineering construction. It shares many similarities with general civil engineering projects such as roads, railways, bridges, and building construction. Water conservancy projects have the following characteristics: hydraulic structures are subjected to water, working conditions are complex, construction is difficult, and natural conditions such as hydrology, meteorology, topography, and geology vary from place to place. Hydrological and meteorological conditions are also unpredictable. Therefore, the design of large-scale water conservancy projects is always unique and difficult to standardize. Large-scale water conservancy projects involve large investments and long construction periods, and have a significant impact on society, the economy, and the environment. They can yield significant benefits, but serious errors or accidents can cause enormous losses or disasters. During the construction of water conservancy projects, warning signs are often placed at the construction site to inform the outside world that construction is underway, ensuring the safety of pedestrians and vehicles near the construction site.

[0003] Existing safety barriers used in water conservancy construction are usually modular. Modular barriers not only occupy a lot of space during transportation, storage and handling, but also require a lot of time and effort to install and dismantle, thus reducing work efficiency. In order to solve the above problems, the inventor proposes a safety protection structure for water conservancy construction. Utility Model Content

[0004] To address the problem that modular safety barriers used in water conservancy construction not only occupy a large amount of space during transportation, storage, and handling, but also require time-consuming and labor-intensive installation and dismantling, thus reducing work efficiency, the purpose of this utility model is to provide a safety protection structure for water conservancy construction.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a safety protection structure for water conservancy construction, comprising a fixed frame and two sliding frames. Universal wheels are rotatably installed at the four corners of the bottom of the fixed frame and the two sliding frames. Two symmetrically distributed rotating shafts are rotatably installed inside the sliding frames. Protective netting is wound around each of the two rotating shafts, and one end of the protective netting is fixedly connected to one side of the corresponding sliding frame. A sliding frame is slidably installed on one side of the fixed frame. First toothed plates are fixedly installed on both sides of the sliding frame. Two symmetrically distributed drive gears are rotatably installed on the side of the fixed frame where the sliding frame is installed, and the drive gears mesh with the corresponding first toothed plates. Support rods are fixedly installed on each of the two drive gears, and warning lights are fixedly installed at one end of each of the two support rods.

[0006] Preferably, a drive shaft is rotatably mounted inside the fixed frame, a half-gear is fixedly mounted on one end of the drive shaft, and a second toothed plate is fixedly mounted on both sides inside the sliding frame, and the half-gear can mesh with the second toothed plate. A drive motor is fixedly mounted on one side of the fixed frame, and the output end of the drive motor is fixedly connected to one end of the drive shaft.

[0007] Preferably, a turntable is fixedly installed at the top of each of the two rotating shafts, and multiple limiting holes are provided on each of the two turntables in a ring. A fixing rod is fixedly installed at the top of the fixing frame, and a sliding plate is slidably sleeved on the fixing rod.

[0008] Preferably, limit rods are fixedly installed at both ends of the lower surface of the sliding plate, and the limit rods can be inserted into the corresponding limit holes. A spring is sleeved on the fixed rod, and the bottom end of the spring contacts the upper surface of the sliding plate.
