Description

Technical Field

[0001] The utility model relates to the technical field of hydropower and water conservancy, in particular to a large-span light-weight floating barrier structure. Background Art

[0002] Currently, hydropower stations and reservoirs typically deploy simple floating barrier structures across the water surface upstream to address upstream debris. However, when dealing with vast expanses of water requiring longer float barriers, particularly in windy areas, large-span float barriers (50 meters or more) are subject to significant crosswind forces. Traditional calculations indicate that such structures would exert significant tension on the infrastructure on both sides of the dam. Maintaining stability would require extensive infrastructure, which not only increases investment costs but also potential operational risks. Utility Model Content

[0003] The utility model provides a large-span light-weight drift-blocking structure, aiming to solve at least one technical problem existing in the prior art mentioned in the background technology.

[0004] The present invention provides the following technical solutions to achieve the above objectives:

[0005] A large-span lightweight float-blocking structure includes concrete foundations symmetrically arranged on both sides, steel cables are arranged between the concrete foundations, and trash nets and roller floats are arranged on the steel cables at intervals in sequence. The roller floats include bearings fixedly arranged on the steel cables, and a plurality of blades are arranged around the bearings.

[0006] Furthermore, the steel wire cable is connected to the concrete foundation through a through-rope, and the through-rope passes through the concrete foundation and is buried in the bedrock.

[0007] Furthermore, eight blades are arranged around the bearing, and the blades are evenly arranged circumferentially on the bearing at 45° intervals with the bearing center as the axis.

[0008] Furthermore, a tension ring is provided at one end of the through-rope away from the concrete foundation.

[0009] Furthermore, the blades are rectangular in structure, with dimensions of 30 cm in length, 20 cm in width and 5 cm in thickness.

[0010] Furthermore, the steel wire cable is provided with an expansion joint.

[0011] Furthermore, the roller float is made of PVC material.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The utility model adopts the roller float design. When encountering a high wind speed on the water surface, the roller float installed on the steel cable can roll on the water surface with the help of wind force, and utilizes the resistance of the water flow to enhance the resistance of the light drift-blocking raft to wind speed, thereby achieving wind reduction.

[0014] The utility model fixes the through ropes to the foundation by passing through the drilled holes in the bedrock, thereby making full use of the resistance of the shore rock mass, further reducing the size of the foundation structure and increasing the stability of the entire structure.

[0015] The utility model ensures that the steel wire cable has sufficient flexibility by arranging the expansion joint, reduces the metal fatigue of the steel wire cable, and prolongs the service life of the steel wire cable. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Example 1. A large-span light-weight floating barrier structure, with reference to Figures 1 to 3 , including concrete foundations 1 symmetrically arranged on both sides, with steel cables 2 arranged between the concrete foundations 1, and characterized in that: a trash net 3 and a roller float 4 are sequentially arranged on the steel cables 2 at intervals, and the roller float 4 includes a bearing fixedly arranged on the steel cables 2, and a plurality of blades are arranged around the bearing.

[0024] The steel cable 2 is connected to the concrete foundation 1 via a through-rope 5, which penetrates the concrete foundation 1 and is embedded in the bedrock. By penetrating the through-rope 5 into the bedrock, the resistance of the shore rock mass is fully utilized, further reducing the size of the foundation structure while also increasing the stability of the entire structure.

[0025] Eight blades are arranged around the bearing, spaced evenly circumferentially at 45-degree intervals around the bearing center. The blades are rectangular, measuring 30 cm long, 20 cm wide, and 5 cm thick. This rectangular configuration increases the contact area between the blades and the water flow, ensuring sufficient contact between the roller float 4 and the water during rotation.

[0026] The end of the through rope 5 away from the concrete foundation 1 is provided with a tension ring. The tension ring is provided to facilitate the connection of the steel wire rope 2 with the through rope 5, and the steel wire rope 2 is fixedly connected to the tension ring.

[0027] The roller float 4 is made of PVC material. Using PVC material as the material of the roller float 4 reduces the weight of the roller float 4 while ensuring the material strength of the roller float 4, thereby reducing the load of the steel cable 2.

[0028] The usage and working principle of the utility model are as follows: the utility model is mainly used in reservoirs, and is set across the reservoir surface. Concrete foundations 1 are excavated on both sides of the reservoir, and the through ropes 5 are fixed in the bedrock. The fixing method can adopt the anchor rod method commonly used in engineering projects, and the through ropes 5 are poured into the concrete foundation 1 along the bedrock surface; the trash nets 3 and roller floats 4 are installed on the wire cables 2 at intervals. The interval distance and the size of the trash nets 3 are selected by the on-site construction personnel according to the engineering requirements; the installation is completed The two ends of the steel wire cable 2 are connected with the through ropes 5 on both sides of the reservoir. In order to facilitate the connection between the steel wire cable 2 and the through ropes 5, a tension ring is provided at the end of the through rope 5 away from the concrete foundation 1, and the steel wire cable 2 is fixedly connected to the tension ring; this light floating raft structure is put into use. When the utility model encounters a large wind speed, the roller float 4 installed on the steel wire cable 2 can roll on the water surface with the help of wind force, and the resistance of the water flow is used to enhance the resistance of the light floating raft to wind speed, thereby achieving wind reduction.

[0029] Example 2. This example has the same structure as Example 1, with the only difference being that, when the reservoir surface is too wide and the required span of the drift barrier is particularly large (greater than or equal to 100 meters), the steel cable 2 is provided with an expansion joint; by providing the expansion joint, the head and tail ends of several steel cables 2 are sequentially connected to form an integral cable spanning the reservoir surface. To ensure that the steel cables 2 have sufficient flexibility and reduce the metal fatigue that may occur in strong winds, the expansion joint is provided to provide the necessary buffer, thereby effectively extending the service life of the steel cables 2.

[0030] Obviously, the above description is only a partial embodiment of the present invention, and not all embodiments. The above embodiments are not intended to limit the present invention. For those skilled in the art, various modifications and variations of the present invention are possible. Any combination, modification, equivalent replacement, improvement, and other embodiments that can be made by those of ordinary skill in the art within the spirit and principles of the present invention shall be within the scope of protection of the present invention.
