Description

Technical Field

[0001] This utility model relates to the field of water conservancy technology, and in particular to an assembled protective railing for water conservancy projects. Background Technology

[0002] Water conservancy projects, in essence, are engineering projects constructed to control and regulate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits; they are also called water engineering. Generally speaking, water conservancy projects typically involve the construction of various types of hydraulic structures such as dams, dikes, spillways, sluices, intakes, canals, ferries, raft channels, and fishways to achieve a more rational allocation of water resources, thereby improving the living and production environment. With the development of the times, people's pursuit of water conservancy projects has gone beyond effectiveness; they are also paying more attention to green and safe features. Generally, the most commonly used safety facility in water conservancy project construction is the guardrail, used to protect dangerous construction areas and prevent pedestrians and vehicles from accidentally falling off the dikes. Depending on the type, size, and location of the dike, different types of guardrails exist. They are simple to use, direct, and effective. However, existing guardrails have simple structures and are mostly fixed, making them inconvenient to assemble and disassemble. Installation and disassembly are time-consuming and labor-intensive, and they occupy a lot of space when stored, while being rather inflexible in use.

[0003] For example, the Chinese authorized utility model patent with announcement number CN215520334U discloses a stable embankment protection device for river channels in water conservancy projects, including multiple guardrails. Each guardrail includes a support column A and a support column B. Multiple horizontal crossbars and vertical uprights are arranged on the inner side of the support column A and support column B. The side of the support column B has a through hole for the crossbar to pass through. The side of the support column A facing the support column B has a groove for placing and supporting the crossbar. A slot is provided at the top of the end of the crossbar facing the through hole. Through the designed through holes and slots, the guardrail can be assembled conveniently and stably. Not only is it not necessary to open screw holes on the surface of the support column A and support column B, but it also ensures stable installation. By reducing the number of screw holes, the installation is convenient for disassembly and assembly, which greatly improves work efficiency. At the same time, the designed connecting column can connect the existing partitioned guardrails into a whole or place them separately according to actual needs.

[0004] This utility model is relatively complete and can meet the protection needs of dangerous construction areas under normal circumstances. It also has a certain combination and adjustment capability. However, it only has the most basic combination function. Not only is the protection strength low, but it is also easy to shift or be deformed by water flow. Furthermore, its modularity is low and it cannot further reduce the effort spent on installation and disassembly. Finally, its function is relatively simple and cannot flexibly meet the complex and ever-changing usage needs of water conservancy projects.

[0005] Therefore, a modular guardrail for water conservancy projects is needed to improve the above-mentioned problems. Utility Model Content

[0006] To overcome the technical defects of the existing technology, this utility model provides an assembled guardrail for water conservancy projects, which has the characteristics of high modularity for easy installation, high component compression to save space, and functions that can be adjusted according to different guardrails installed.

[0007] The technical solution adopted by this utility model is: an assembled guardrail for water conservancy projects, including a base, a mesh guardrail and an assembled guardrail. A top horizontal plate is provided above the base. Post slots are opened at the top of the base and the bottom of the top horizontal plate. Slot baffles are fixedly installed at both ends of the post slots. Several post screw holes are opened at the top of the base and the bottom of the top horizontal plate. Combined posts are snapped between the base and the top horizontal plate. Several ground-fixing plates are fixedly welded to the outside of the base. Each ground-fixing plate has threaded holes inside, and ground-fixing screws are screwed into the threaded holes. A snap-fit ​​block is fixedly installed on the top of each ground-fixing plate. An upper connecting plate is fixedly installed on one side of some of the snap-fit ​​blocks, and a lower connecting plate is fixedly installed on one side of other snap-fit ​​blocks. Connecting screws are screwed into the interior of the upper connecting plate, and connecting threaded holes are opened inside the lower connecting plate.

[0008] Preferably, to facilitate the unfolding of the combined columns, the combined columns include an outer column and an inner column on one side. Both the outer and inner columns have connecting rod grooves on one side, and a column connecting rod is engaged inside the connecting rod groove. An upper rotating shaft is fixedly installed at the top of the column connecting rod, and a lower rotating shaft is fixedly installed at the bottom of the column connecting rod. The upper rotating shaft is rotatably connected to the outer column. A sliding groove is opened inside the connecting rod groove on one side of the inner column, and the lower rotating shaft is engaged with the sliding groove.

[0009] Preferably, in order to fix the base, the combined uprights, and the top horizontal plate, the top ends of both the outer and inner uprights are fixedly installed with upper snap-fit ​​ports, and the bottom ends of both the outer and inner uprights are fixedly installed with lower snap-fit ​​ports. The upper snap-fit ​​ports snap into the top horizontal plate, and the lower snap-fit ​​ports snap into the base. The top ends of both the outer and inner uprights are fixedly installed with top fixing plates, and top fixing screws are screwed into the interior of the top fixing plates. The bottom ends of both the outer and inner uprights are fixedly installed with bottom fixing plates, and bottom fixing screws are screwed into the interior of the bottom fixing plates. The dimensions of the top fixing screws and the bottom fixing screws correspond to the screw holes of the uprights.

[0010] Preferably, to address different protection scenarios, protective plates with different functions are provided. The mesh protective plate includes a mesh frame with several mesh fixing threaded holes on its outer side. An anti-corrosion metal mesh is fixedly installed inside the mesh frame. The assembled plate protective plate includes an assembled plate frame with several assembled plate fixing threaded holes on its outer side. A connecting horizontal plate is provided on the inner side of the assembled plate frame with several horizontal plate fixing threaded holes. Several protective plates are snapped into the inner side of the assembled plate frame. Several assembled plate fixing screws are screwed to both ends of each protective plate. A snap-fit ​​side plate is fixedly installed on one side of the outer column. Several protective plate fixing screws are screwed to both ends of the snap-fit ​​side plate. Both the mesh protective plate and the assembled plate protective plate can be snapped together by the snap-fit ​​side plate and further fixed by the protective plate fixing screws in conjunction with the mesh fixing threaded holes and the assembled plate fixing threaded holes.

[0011] The beneficial effects of this utility model are:

[0012] 1. This utility model is highly modular, and is formed by combining various components to form a whole, which is easy to install, store and transport. It saves time and effort during installation and disassembly, occupies little space when stored, and is extremely flexible in use. In addition, screws are used to fix many joints, which makes it sturdy and durable, not easy to be damaged or fall apart and deformed, further increasing the safety of water conservancy projects.

[0013] 2. This utility model addresses different usage scenarios by setting different types of protective plates. For example, the prepared mesh protective plate is generally used when the hydrological environment around the water conservancy project is relatively mild, reducing the impact of water and wind on the protective plate and preventing pedestrians and vehicles from accidentally falling off the embankment. Its main function is "internal protection." The prepared assembled plate protective plate, on the other hand, uses a higher-strength composite plate for comprehensive protection. It is mainly for more severe hydrological environments, preventing waves inside the embankment from impacting the shore and causing pedestrians and vehicles to be impacted and suffer accidents. Its main function is "external defense." It can be selected according to different situations and is flexible and practical. Attached Figure Description
