Description

Technical Field

[0001] This utility model relates to the field of water pipe supporting equipment technology, and in particular to a scour-proof stepping stone for a hydrological station. Background Technology

[0002] Hydrological stations, as crucial infrastructure for monitoring river hydrological data, use access steps that serve as key passageways for staff conducting water level observations and water quality sampling. In the complex and ever-changing hydrological environment, these access steps must withstand the long-term effects of water flow erosion and water level fluctuations, while ensuring the safety of personnel. Therefore, designing access steps with erosion resistance and adaptability to water level changes is of great significance for improving the safety and efficiency of hydrological monitoring work.

[0003] Existing hydrological station access steps generally suffer from simple structures and insufficient protective capabilities. Firstly, some steps lack effective erosion prevention measures, and under long-term water erosion, the surface of the steps is prone to wear and collapse, shortening the service life of the facilities. Secondly, traditional protective fences are mostly designed with a fixed height and cannot be dynamically adjusted with the rise and fall of water levels. When the water level rises, the fence loses its protective function, and when the water level falls, it hinders the movement of staff. Utility Model Content

[0004] The main purpose of this utility model is to provide a scour-resistant stepping stone for hydrological stations, so as to solve the defects of existing steps that are easily scourted, resulting in a short service life and difficulty in combining protection and convenience.

[0006] Furthermore, the protective component includes: a movable groove formed within the main body, the movable groove being located on both sides of the inner cavity; a movable fence disposed on the top of the main body, the movable fence having a float at its bottom, the float being connected to a float block at its bottom, and the float block being slidably connected to the movable groove.

[0007] Furthermore, a handrail is provided on the side of the step away from the inner wall of the inner cavity, and the handrail is parallel to the step.

[0008] Furthermore, the movable groove is cylindrical in shape, and the float is spherical in shape.

[0011] Furthermore, a drainage trough is provided on the side of the step away from the handrail.

Detailed Implementation

[0014] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0015] like Figure 1-5As shown, this embodiment provides an example of a scour-resistant hydrological station access step. The scour-resistant hydrological station access step includes: a main body 100, with an inner cavity 110 inside, and multiple layers of steps 200 inside the inner cavity 110; multiple scale marks 140, which are located on the inner wall of the inner cavity 110 and are equidistantly distributed among each other; a scour-resistant plate 220, located on the side of the steps 200 away from the inner cavity 110, for preventing water scour; and a protective component 300, located on the top of the main body 100, for preventing pedestrians from falling.

[0016] The protective component 300 includes: a movable groove 310 opened in the main body 100, the movable groove 310 being located on both sides of the inner cavity 110; a movable fence 320 provided on the top of the main body 100, the bottom of the movable fence 320 being provided with a float 322, the bottom of the float 322 being connected to a float block 321, and the float block 321 being slidably connected to the movable groove 310.

[0017] During use, the main body 100 serves as the basic load-bearing structure, the inner cavity 110 provides the internal working space, and multiple layers of steps 200 are arranged longitudinally along the inner wall of the inner cavity 110, forming a channel for accessing the river. Workers use the steps to move between the river surface and the bank. The inner cavity 110 provides a wrapping support for the steps 200, ensuring their stability under the impact of water flow. The structure of the inner cavity 110 provides rigid support for the steps 200, enhancing their overall anti-overturning ability and adapting to the long-term immersion environment of the hydrological station. Simultaneously, the anti-scouring plate 220 is fixed to the water-facing side of the steps 200, away from the inner cavity 110. When water impacts the steps 200, the anti-scouring plate 220 first bears the impact force, dispersing it to the main body of the steps 200 through its own structure, reducing direct scouring and erosion of the steps 200 surface.

[0018] When the water level rises, multiple scales 140 are used as a water gauge. These scales 140 are equidistantly located on the inner wall of the inner cavity 110. As the water level changes, the water surface aligns with the scales, and staff can directly read the water level data by observing the position of the scales 140. The equidistant distribution ensures standardized scale spacing, facilitating rapid calculation of water level height.

[0019] When the water level rises, the float 321 slides upward along the movable channel 310 under the action of buoyancy, causing the movable fence 320 to rise synchronously. At this time, even if pedestrians and staff cannot see the position of the inner cavity 110 due to the rising water level, they can still judge the position of the inner cavity 110 by observing the movable fence 320, thus preventing accidental falls. When the water level drops, the float 321 falls back with the water level, and the movable fence 320 lowers. After falling back, the movable fence 320 allows pedestrians and staff to enter the inner cavity 110, while always keeping the height of the movable fence 320 above the water surface to prevent pedestrians from falling.

[0020] The step 200 is equipped with a handrail 210 on the side of the inner wall away from the inner cavity 110. The handrail 210 is parallel to the step 200 and fixed to the step 200. When workers go up or down the step 200, they can hold the handrail 210 to maintain their balance. Especially when the step 200 is slippery or when carrying equipment, the handrail 210 provides additional support to help workers move stably in complex environments such as at night or in turbulent water, thus ensuring work safety.

[0021] The movable channel 310 has a cylindrical structure, while the float 321 has a spherical structure. The cylindrical movable channel 310 and spherical float 321 work together to form a point-contact sliding mechanism. Under buoyancy, the float 321 can slide freely up and down along the cylindrical movable channel 310, reducing sliding friction and ensuring smooth, unimpeded movement of the movable enclosure 320 as the water level changes. This low-friction design makes the movable enclosure 320 more sensitive to water level changes, preventing protective failure due to jamming.

[0022] The movable enclosure 320, float 321, and float rod 322 are equipped with cavities filled with air to reduce overall density and increase buoyancy. When the water level rises, the cavity structure provides sufficient buoyancy to ensure that the float 321 drives the movable enclosure 320 to float stably; when the water level falls, the cavity reduces its own weight to prevent the movable enclosure 320 from being excessively depressed.

[0023] The main body 100 has a base plate 120 at its bottom and an inclined retaining wall 130 on the side of the main body 100 away from the inner cavity 110. The base plate 120 is fixed to the bottom of the main body 100 and is connected to the riverbed foundation by pre-embedded bolts or concrete pouring to provide vertical support. The retaining wall 130 is inclined on the back side of the main body 100 to provide more stable soil pressure and maintain the overall stability of the structure. The vertical component force is borne by the base plate.

[0024] The step 200 has a drainage channel 230 on the side away from the handrail 210. When rainwater or splashing water accumulates on the step 200, the water flows downhill along the drainage channel 230 and eventually into the river, preventing water from stagnating on the surface of the step 200. This rapid drainage keeps the surface of the step 200 dry, reducing the risk of falls due to slipperiness; it also reduces long-term immersion corrosion of the step 200 by water accumulation, extending the service life of the step 200.

For those skilled in the art, any equivalent modifications or substitutions to the utility model are also within the scope of the utility model. Therefore, all equivalent transformations, modifications, and improvements made without departing from the spirit and principles of the utility model should be covered within the scope of the utility model.
