The purpose of the utility model is realized through the following ways: a buoyancy self-opening type left-row safety door comprises a wall body fixing outer frame, wherein the outer frame is fixed on a wall and a foundation of an inlet and an outlet of a drainage culvert, a safety door frame is movably arranged in the wall body fixing outer frame, and the wall body fixing outer frame and the safety door frame are hinged through a connecting rotating shaft at the bottom;
the middle part of one side of the safety door frame is provided with a safety buoy protection box, and a safety buoy is arranged in the box;
the top of the safety buoy is fixed with an early warning vertical ejector rod, the top of the early warning vertical ejector rod is movably connected with an early warning transverse lever through a transverse vertical ejector rod linking shaft, the middle section of the early warning transverse lever is movably connected with a safety door frame through an early warning transverse lever fulcrum shaft, the outer end of the early warning transverse lever is provided with a safety door switch locking hook, and the safety door switch locking hook is hung at the top of a fixed outer frame of a wall hanging body when the safety door is in a closed state.
As a further optimization of the scheme, the safety door frame is formed by arranging a safety door fixing transverse pipe and a safety door fixing vertical pipe.
The utility model discloses buoyancy is from open safety door of arranging on the left, and prior art compares, and the device has following characteristics: firstly, people and animals can be prevented from entering the culvert in all weather to cause casualties under the condition of no natural disasters such as flood and the like, and the safety door device is automatically opened when large flood occurs, so that the flood is prevented from flowing smoothly to block and drain water to form flood disasters; secondly, after the flood passes, safety guards close the safety door device, thereby saving the safety guards, reducing the workload, reducing the management cost of the main canal drainage culvert and removing the potential safety hazard; thirdly, safety personnel can not be needed to nurse all the weather, the technology is advanced, and the structure is simple.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings:
FIG. 1 is a schematic view of the overall structure of the present invention;
FIG. 2 is a schematic side view of the closed state of the present invention;
FIG. 3 is a schematic side view of the open state of the present invention;
in the figure, a wall body fixing outer frame 1, a safety door frame 2, a safety door fixing vertical pipe 3, a safety door fixing horizontal pipe 4, a safety buoy 5, a safety buoy protection box 6, an early warning vertical ejector rod 7, a horizontal and vertical ejector rod linking shaft 8, an early warning horizontal lever fulcrum shaft 9, a safety door switch locking hook 10, an early warning horizontal lever 11 and a connecting rotating shaft 12.
Detailed Description
As shown in fig. 1 and 2, the buoyancy self-opening type left-row safety door of the present invention comprises a wall-fixing frame 1 fixed on the wall and the foundation of the inlet and outlet of the drainage culvert, a safety door frame 2 movably installed inside the wall-fixing frame 1, and the two are hinged through a connecting shaft 12 at the bottom;
a safety buoy protection box 6 is arranged in the middle of one side of the safety door frame 2, and a safety buoy 5 is arranged in the box;
5 tops of safe flotation pontoon are fixed with an early warning and erect ejector pin 7, and the early warning erects the top of ejector pin 7 and passes through the horizontal lever 11 of 8 swing joint early warning of ejector pin interlinkage axle, and the horizontal lever 11 middle section of early warning passes through horizontal lever fulcrum axle 9 of early warning and 2 swing joint of safe door frame, and 11 outer ends of early warning horizontal lever are provided with safety door switch locking hook 10, and safety door switch locking hook 10 hangs in hanging wall body fixed frame 1 top during emergency exit closed condition.
The safety door frame 2 is composed of a safety door fixing horizontal tube 4 and a safety door fixing vertical tube 3 which are arranged.
As shown in fig. 2 and 3, the buoyancy self-opening left-discharge safety door of the present invention has the following working processes:
firstly, under the condition that the flood water level is lower than 1.5 meters, the safety door is in a closed state, and normal drainage is not influenced;
secondly, under the special condition that the water level is higher than 1.5 meters and flood occurs, the flood disaster endangers the main canal due to the fact that water flow is too large and the water flow is not smooth to block and drain, as long as the water level is higher than 1.5 meters and more, the water floats the safety buoy, the safety buoy pushes the safety buoy early warning vertical ejector rod upwards to act on the horizontal and vertical ejector rod link shaft, the early warning transverse lever is driven by the axial support stress of the early warning transverse lever fulcrum shaft, the safety door switch locking hook is separated from the locking position to open and lock, the buoyancy self-opening type left discharge safety door is separated from the upper end of the wall body fixing outer frame from the upper part, the lower part of the safety door is automatically opened along the water flow direction by the rotation of the bottom connecting rotating shaft, an included angle smaller than 90 degrees is formed between the wall body fixing outer frame and the safety door frame, the safety buoy protection box supports the safety door frame by abutting against, the safety of the main channel is protected;
thirdly, after the flood passes through, the main canal safety management personnel carry out system safety check on the buoyancy self-opening type left discharge safety doors of all the drainage culverts, uniformly close the buoyancy self-opening type left discharge safety door switch locking system, and restore the closed state before the flood occurs, so that all work is completed.
The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can be covered within the protection scope of the present invention without the changes or substitutions thought by the inventive work within the technical scope of the present invention.
