Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a multifunctional safety guardrail for water conservancy engineering construction sites. Background Technology

[0002] Multifunctional safety guardrails at water conservancy project construction sites are crucial facilities for ensuring construction safety. The guardrails are scientifically designed to prevent accidental falls of personnel and tools, ensuring safety at the edges of the construction site. Temporary lighting can also be installed to ensure visibility in low-light conditions. Some guardrails are also designed with operable access gates for the orderly entry and exit of construction personnel and vehicles, with secure locks to prevent unauthorized entry. Furthermore, the guardrails are structurally stable, easy to install, and adaptable to different terrains and construction stages, effectively reducing safety risks at water conservancy project construction sites.

[0003] For example, utility model CN211597992U discloses a safety guardrail, including a guardrail body. Connecting legs are fixedly connected to both sides of the bottom of the guardrail body. A first groove is formed at the top and bottom of one side of the guardrail body. A rotating block is movably connected to the inside of the first groove via a first rotating shaft. A second groove is formed on one side of the rotating block. Plastic plates are fixedly installed at the top and bottom of the second groove. Connecting blocks are fixedly connected to one side of each plastic plate. This safety guardrail, through the design of the first groove, rotating block, second groove, and first rotating shaft, allows the user to adjust the angle of the rotating block arbitrarily, facilitating user operation. The design of the plastic plates, connecting blocks, limiting blocks, connecting rods, and locking blocks allows for easy installation when two guardrails need to be joined together, making operation simple and convenient.

[0004] The above applications currently have the following shortcomings:

[0005] Rising water levels can affect the effectiveness of interception. Utility Model Content

[0006] This utility model discloses a multi-functional safety guardrail for water conservancy engineering construction sites, which aims to solve the technical problem that the interception effect is affected when the water level rises.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A multifunctional safety guardrail for water conservancy construction sites includes a base plate, with ground nails fixedly connected to the lower surface of the base plate, and a limiting sleeve fixedly connected to the upper surface of the base plate. A pressing mechanism is rotatably connected to the inner cavity of the limiting sleeve. The pressing mechanism includes a rotating rod, with a connecting plate fixedly connected to the end of the rotating rod. A foam board is fixedly connected to the lower part of the connecting plate on the side away from the rotating rod. A fixing rod is fixedly connected to the outer surface of the limiting sleeve, with a limiting tube fixedly connected to the end of the fixing rod. A first guardrail plate is symmetrically fixedly connected to the outer surface of the limiting tube. A movable guardrail plate mechanism is slidably connected to the inner cavity of the limiting tube. The movable guardrail plate mechanism includes a sliding rod, which is slidably connected to the inner cavity of the limiting tube. A second guardrail plate is installed on the outer surface of the top end of the sliding rod.

[0009] By setting ground nails, the base plate can be firmly inserted into the soil, thus positioning it in the soil at the construction site. By setting a limiting sleeve, the extrusion mechanism can be limited, allowing it to rotate around the limiting sleeve. The extrusion mechanism supports the device and, when the river level rises, compresses the movable guardrail mechanism, causing it to move upwards. The first guardrail can block the riverbank. The movable guardrail mechanism allows for height adjustment when the river level rises, preventing people from approaching the river and causing harm. The limiting tube limits the sliding rod, allowing it to move vertically within the limiting tube's cavity.

[0010] In a preferred embodiment, a barbed plate is fixedly connected to the lower surface of the foam board, and the number of the barbed plates is several and they are evenly distributed. A bent rod is fixedly connected to the side of the connecting plate away from the rotating rod, and a compression ball is fixedly connected to the end of the bent rod.

[0011] By setting up foam boards, the foam boards will float when the water level rises. By setting up barbed plates, the foam boards can be tightly connected to the soil. By setting up squeezing balls, the squeezing balls can squeeze the movable guardrail mechanism when the foam boards rise due to the rising water level.

[0012] In a preferred embodiment, the movable guardrail mechanism further includes a baffle plate that penetrates the limiting tube. A circular hole is formed on the upper surface of the baffle plate. A pressing plate is fixedly connected to the side of the lower surface of the baffle plate, and the pressing plate is adapted to press against a pressing ball. The movable guardrail mechanism also includes a first spring, which is fixedly connected to the bottom surface of the inner cavity of the limiting tube. A pressing block is fixedly connected to the top end of the limiting tube, and the pressing block is adapted to press against the lower surface of the baffle plate. A fixing plate is fixedly connected to the upper surface of the baffle plate away from the pressing plate. A second spring is fixedly connected to the outer surface of the fixing plate, and a fixing block is fixedly connected to the end of the second spring. The fixing block is fixedly connected to the outer surface of the limiting tube. There are two second guardrails, and the two second guardrails are symmetrically fixedly connected to the outer surface of the top end of the sliding rod.

[0013] By setting a baffle plate, the internal space of the limiting tube can be divided. By setting a compression plate, the compression plate can be squeezed when the compression ball moves, thereby causing the baffle plate to move within the cavity of the limiting tube. By setting a first spring, elastic potential energy can be stored, allowing the compression block to move upward quickly when unobstructed. By setting a second spring, a compressive force can be applied to the baffle plate, resulting in a rebound after the baffle plate moves. By setting second guardrails on both sides of the outer side of the sliding rod, personnel can be blocked.

[0014] As can be seen from the above, a multi-functional safety guardrail for water conservancy engineering construction sites has the following improvements and advantages compared with existing technologies;

[0015] Firstly, by setting ground nails, the base plate can be firmly inserted into the soil, thus positioning it in the soil at the construction site. By setting a limiting sleeve, the extrusion mechanism can be limited, allowing it to rotate around the limiting sleeve. By setting the extrusion mechanism, the device can be supported, and when the river level rises, the extrusion mechanism can extrude the movable guardrail mechanism, thereby allowing the movable guardrail mechanism to move upward. By setting the first guardrail, the riverbank can be blocked.

[0016] Secondly, by setting up a movable railing mechanism, the height of the railing can be adjusted when the river water level rises, thereby preventing people from approaching the river and causing harm. By setting up a limiting tube, the sliding rod can be limited, allowing the sliding rod to move vertically within the inner cavity of the limiting tube. Attached Figure Description

Ground nails 2 are fixedly connected to the lower surface of the base plate 1. A limiting sleeve 3 is fixedly connected to the upper surface of the base plate 1.

The movable guardrail mechanism 8 includes a sliding rod 89, which is slidably connected to the inner cavity of the limiting tube 6. The top of the sliding rod 89... The outer surface is equipped with a second guardrail 810. By setting ground nails 2, it can be firmly inserted into the soil, thereby positioning the base plate 1 in the soil of the construction site. By setting a limiting sleeve 3, the squeezing mechanism 4 can be limited, allowing the squeezing mechanism 4 to rotate around the limiting sleeve 3. By setting the squeezing mechanism 4, while supporting the device, it can also squeeze the movable guardrail mechanism 8 when the river level rises, thereby allowing the movable guardrail mechanism 8 to move upward. By setting a first guardrail 7, the riverbank can be blocked. By setting the movable guardrail mechanism 8, the height of the guardrail can be adjusted when the river level rises, thereby preventing people from approaching the river and causing harm. By setting a limiting tube 6, the sliding rod 89 can be limited, allowing the sliding rod 89 to move vertically within the cavity of the limiting tube 6.

[0026] Reference Figure 1 and Figure 3 In a preferred embodiment, a barbed plate 44 is fixedly connected to the lower surface of the foam board 43. The number of barbed plates 44 is several, and the barbed plates 44 are evenly distributed. By setting the foam board 43, the foam board 43 can float when the water level rises. By setting the barbed plates 44, the foam board 43 can be tightly connected to the soil. A bent rod 45 is fixedly connected to the side of the connecting plate 42 away from the rotating rod 41. A compression ball 46 is fixedly connected to the end of the bent rod 45. By setting the compression ball 46, when the foam board 43 rises due to the rise in water level, the compression ball 46 can compress the movable guardrail mechanism 8.

[0027] Reference Figure 1 and Figure 4In a preferred embodiment, the movable guardrail mechanism 8 further includes a baffle plate 83 that penetrates the limiting tube 6. A circular hole 84 is formed on the upper surface of the baffle plate 83. A pressing plate 85 is fixedly connected to the side of the lower surface of the baffle plate 83. The pressing plate 85 is adapted to press against the pressing ball 46. By setting the baffle plate 83, the internal space of the limiting tube 6 can be divided. By setting the pressing plate 85, the pressing ball 46 can press against the pressing plate 85 when it moves, thereby causing the baffle plate 83 to move within the cavity of the limiting tube 6. The movable guardrail mechanism 8 also includes a first spring 81, which is fixedly connected to the bottom surface of the cavity of the limiting tube 6. A pressing block 82 is fixedly connected to the top of the limiting tube 6, and the pressing block 82 is adapted to press against the lower surface of the baffle plate 83.

A fixing plate 86 is fixedly connected to the upper surface of the barrier plate 83 away from the extrusion plate 85. A second spring 87 is fixedly connected to the outer surface of the fixing plate 86. A fixing block 88 is fixedly connected to the end of the second spring 87. The fixing block 88 is fixedly connected to the outer surface of the limiting tube 6. By setting the second spring 87, an extrusion force can be applied to the barrier plate 83, so that the barrier plate 83 can rebound after moving. There are two second guardrails 810, and the two second guardrails 810 are symmetrically fixedly connected to the outer surface of the top of the sliding rod 89. By setting the second guardrails 810 on both sides of the outer side of the sliding rod 89, personnel can be blocked.

[0028] Working principle: When in use, the operator places the base plate 1 on the river soil and inserts the ground nail 2 deep into the soil cavity. When the river water level rises, the foam board 43 is buoyed by the rising water level, causing the connecting plate 42 and the rotating rod 41 to rotate. This causes the extrusion ball 46 to extrude the extrusion plate 85. When the extrusion plate 85 is extruded, the baffle plate 83 moves laterally until the round hole 84 is located in the cavity of the limiting tube 6, thereby causing the extrusion block 82 to move upward and extrude the bottom end of the sliding rod 89, thereby raising the second guardrail 810.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
