Description

A simple drift-stopping device for a floating island-type reservoir

technical field

The invention relates to a simple drift-stopping device for a floating island type reservoir, which belongs to the technical fields of water conservancy, hydropower and civil engineering construction.

Background technique

Judging from the current situation, after the water conservancy project is closed to store water to form a reservoir, various floating objects flow into the reservoir and collect in front of the reservoir dam (or in front of the water inlet), and accumulate more and more over time, especially during floods. . This problem exists to varying degrees in many domestic hydropower stations and reservoirs, and it is a problem that is difficult to solve completely. At present, when there are many floating objects and affect the operation of the hydropower station, many hydropower stations install another trash rack (or trash rack) in front of the trash rack. Floating trash racks are generally used in China. When designing floating trash racks for similar projects at present, they are designed according to the support points at both ends of the floating trash racks. There are mainly two types, one is fixed, and the other is It is a vertical lifting activity type. The structure of the floating trash rack with fixed supports at both ends is simple and convenient for construction, but it can only be used when the water level of the reservoir does not fluctuate greatly. ; The vertically lifting movable floating trash rack can be vertically lifted with the change of the water level of the reservoir when the water level of the reservoir is relatively large by means of the vertical walking trolley installed in the concave track of the fixed pier at both ends. There is a gap, but the vertical traveling trolley needs to use the hoist to control the lifting or lowering amplitude according to the change of the reservoir water level through the automatic control device, so as to ensure that the trash row will not be submerged in the water or suspended in the air due to the rise and fall of the reservoir water level. Most hydropower stations in China use fixed trash racks. These trash racks are installed with one end fixed on the flood discharge pier between the plant dams and the other end fixed farther upstream, forming a smaller angle with the direction of water flow to reduce waste Hydraulic impact on trash rack. This kind of trash block generally does not have the function of navigating, and in special cases, it is necessary to manually untie a certain link in the fixed wire rope to realize navigating. In addition, the trash rack does not have the function of being able to move to other waters in the reservoir area at any time to perform tasks as needed.

At present, relying on manpower to clean up floating garbage in the reservoir area has low efficiency and high labor costs, and it is difficult to meet the needs of maintaining the water environment in the reservoir area, especially the need for mobile emergency slag removal. And when cleaning up the trash rack, the staff can't go to the shore for a long time, and the fatigue work is easy to cause accidents and endanger the safety of personnel. There is an urgent need for a stable and convenient rest platform to provide a suitable rest place for the staff.

At present, there is a utility model patent CN203475401U simple drift arresting device for water conservancy facilities such as reservoirs. Zhang Yuqiao et al. have a simple floating arresting device. Adjustable main cables are hung on both sides of the water. The lower part is connected to the grid, and the grid is fixed on the water surface through the tension of the main cable and the buoyancy of the buoyancy tank, so as to achieve the function of intercepting floating objects;

The utility model patent CN203247560U of Cao Guangrong et al. is a solid float type rubber barrier. The rubber barrels are connected in series through an adjustable length anchor rope, and the device floats on the water surface by the buoyancy of the rubber barrels to deal with floating objects;

The utility model patent CN203755248U of Chen Qichun and Li Banghong’s utility model patent CN203755248U slides the floating tanks into one body with cross hinges to form a floating tank assembly. The end is connected with the trolley through a cross hinge, and the whole set of drift stopping device can automatically adapt to the change of water level, adjust the height of the drift stopping device, and have better working performance;

The utility model patent CN202899089U of Huang Bensheng, Liu Da, etc. is a liftable rigid floating retaining system that can be used for the water inlet of large-scale power stations. By using at least one rigid long straight piece, it is connected with the floating piece and floats on the water surface in a horizontal state. Block floating objects. Floating objects mean that the entire floating blocking assembly can change with the water level. The rigid long straight parts make the entire assembly not easily damaged by water, and can also rely on its own rigidity to guide larger floating flows to the downstream of the power station;

Zhou Ran and Zhou Xinjing's utility model patent CN204385710U two-way open and close drift blocking device, through two symmetrically arranged two-way floating blocking units, realizes the interception of floating objects on the water surface and underwater pollution impurities in both positive and negative water flow directions, because the entire device It is a diamond-shaped symmetrical structure, the system is relatively stable when it works, and has a long service life;

The utility model patent CN204674793U of Huang Hongbo and Yang Yaqi is a lift-type ship passing device. Liftable buoys are installed at both ends of the water surface retaining net. Lifting, when there are ships, raise the net to provide passage, and lower the net to intercept floating objects at other times, it does not have the ability to provide passage for ships and intercept floating objects at the same time;

According to many patents, it can be known that many drift arresting devices do not have the ability for ships to navigate; some can provide navigation, but they cannot intercept floating objects when providing navigation, such as CN204674793U, a lifting type ship passing device by Huang Hongbo et al.; When a certain part of the drift-stopping device is damaged, it needs to stop working for maintenance or even replace it as a whole, which increases the difficulty of maintenance; based on humanized considerations, many drift-stopping devices do not mention a device for the staff to take a short rest Or method; This just urgently needs a kind of drift arresting system that can maintain conveniently, cost is lower, and have navigable floating platform.
