Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy and hydropower construction, and more specifically, to a warning sign for water conservancy and hydropower construction. Background Art

[0002] There are many similarities between the construction of water conservancy and hydropower and the construction of general civil engineering such as roads, railways, bridges and housing. The construction of water conservancy projects also has its own characteristics: ① Water conservancy projects undertake the tasks of water retaining, water storage and water discharge, so they have special requirements for the stability, pressure bearing, anti-seepage, impact resistance, wear resistance, frost resistance and crack resistance of hydraulic structures. It is necessary to adopt special construction methods and measures in accordance with the technical specifications of water conservancy projects to ensure the quality of the project. ② Water conservancy projects have strict requirements on the foundation, and the projects are often located in areas and parts with complex geological conditions. If the foundation is not properly treated, it will leave hidden dangers, which are difficult to remedy afterwards. Special foundation treatment measures are required. ③ Water conservancy projects are mostly constructed in rivers, lakes, coastal areas and other waters. Construction diversion, interception and underwater operations need to be carried out according to the natural conditions of the water flow and the requirements of engineering construction. ④ Water conservancy projects should make full use of the dry season for construction, which has strong seasonality and necessary construction intensity. Some projects need to take temperature control measures due to climate influence to ensure the quality of the project. The construction of water conservancy projects is closely related to the social and natural environment, so the impact of the implementation of the project is also relatively large. It is necessary to seize the opportunity, arrange plans reasonably, carefully organize the construction, and promptly solve problems such as flood prevention and flood crossing during construction to ensure safety. Warning signs are needed during water conservancy and hydropower construction to warn passers-by in the surrounding area.

The base 1 is composed of two bottom plates, the bottoms of the two bottom plates are hinged so that the two bottom plates can be flipped and folded downward. At least two sets of buckles are arranged between the tops of the two bottom plates. The top of the base 1 is connected with a mounting sleeve 8 by bolts. The mounting sleeve 8 is composed of two semi-annular mounting rings, one mounting ring is fixedly arranged on the top of one bottom plate, and the other mounting ring is fixedly arranged on the top of the other bottom plate. A locking block 7 is connected in the mounting ring by bolts, and a locking groove 10 is opened at the bottom end of the support rod corresponding to the locking block 7; a placement groove is opened on one side of the fixed plate 2, and a warning cardboard 3 is placed in the placement groove; the fixed plate 2 is composed of two connecting plates, the two connecting plates are hinged, and the bottoms of the connecting plates are connected by A mounting block 22 is connected by bolts, and mounting grooves 23 are provided on opposite sides of the two mounting blocks 22. A wedge-shaped block 25 is slidably connected in the mounting groove 23. A limit spring 24 is connected between the bottom of the mounting groove 23 and the wedge-shaped block 25 by bolts. The top of the support rod is connected to the mounting plate 20 by bolts. Limiting grooves 21 adapted to the wedge-shaped block 25 are provided on both sides of the mounting plate 20. The inclined surfaces of the two wedge-shaped blocks 25 are opposite and face the mounting plate 20. A sliding opening 26 penetrating to the mounting groove 23 is provided at the bottom of the mounting block 22. A sliding plate 27 extending out of the sliding opening 26 is connected to the bottom of the wedge-shaped block 25 by bolts; the bottom of the bottom plate is connected to an anti-skid pad 9 by bolts, and the anti-skid pad 9 is used to prevent the base 1 from slipping. At the same time, the base 1 is supported to avoid the instability of the base 1 caused by the installation of the hinge.

[0026] Reference Figure 1 and Figure 4 The support rod includes a support sleeve 5 and a movable rod 6. The movable rod 6 is inserted into the support sleeve 5. The locking groove 10 is provided at the bottom end of the support sleeve 5. The mounting plate 20 is connected to the top of the movable rod 6 by bolts. The movable rod 6 and the support sleeve 5 are used to facilitate the contraction of the support rod. A mounting shell 11 is connected to one side of the top of the support sleeve 5 by bolts. The support sleeve 5 has a connecting port 13 corresponding to the mounting shell 11. A fixing block 12 is slidably connected to the mounting shell 11.

The limiting block 4 is used to facilitate the installation and disassembly of the warning cardboard 3; the limiting block 4 is wedge-shaped and the inclined surface faces the warning cardboard 3. The wedge-shaped design makes it easy for the warning cardboard 3 to squeeze the limiting block 4 and shrink into the movable groove 17 when the warning cardboard 3 is installed.

[0028] Working principle: When transporting the device, first pull the support rod to remove the support rod from the installation sleeve 8, then open the buckle, fold the base 1, and then pull the sliding plate 27, and drive the wedge-shaped block 25 to move through the sliding plate 27, so that the wedge-shaped block 25 is separated from the limiting groove 21, and the support rod can be separated from the fixed plate 2. The separated fixed plate 2 and the base 1 can be folded, thereby reducing the occupied space of the device and achieving the purpose of convenient transportation. When installing, similarly, first restore the base 1, then close the buckle, and insert the locking block 7 corresponding to the locking groove 10 of the support rod into the installation sleeve 8 to complete the installation of the support rod. At the same time, insert the mounting plate 20 between the two mounting blocks 22, and squeeze the inclined surface of the wedge-shaped block 25 through the mounting plate 20, so that the wedge-shaped block 25 shrinks into the mounting groove 23. When the wedge-shaped block 25 corresponds to the limiting groove 21, the elastic force of the limiting spring 24 pushes the wedge-shaped block 25 into the limiting groove 21, thereby completing the assembly.
