Description

Hanging grid for intercepting floating objects

Technical Field

The utility model relates to a hanging grid, especially relate to a hanging grid that is used for floater interception, adjustable length belongs to hydraulic equipment technical field.

Background

The floating objects on the water surface of the river course are easy to gather in front of the concave bank and the river blocking dam of the river course along the river course, thereby not only having adverse effects on the water quality along the river course, the water landscape, the water supply, the aquatic products, the shipping and the like, but also reducing the power generation benefit of the hydropower hub and threatening the operation safety of the hub. While floaters generally originate from: 1. the natural garbage, roots, branches, leaves, weeds and the like of plants enter rivers along with water after being washed by rainwater and are collected on the water surface to form natural floaters; 2. domestic garbage, which is caused by the aggravation of human production activities and the out-of-control management to enter rivers to form artificial floaters; 3. aquatic plant floating materials are generated by rampant spreading of water hyacinth, duckweed and the like caused by eutrophication of water bodies; 4. floaters such as ice blocks, ice scraps and the like in winter in cold regions also form solid floaters on the water surface.

In the existing float blocking equipment, floating boxes are generally adopted for blocking, namely a plurality of floating boxes are connected into a floating box row, but the blocking mode can only effectively block larger floaters on the water surface, and is ineffective for blocking floaters which are not floated below the water surface; and the interception of floaters with small volume is ineffective, and the floaters with small volume easily pass through the gap of the float blocking equipment or enter the working area of the hydraulic turbine unit from the bottom of the float blocking equipment, so that the normal work of the hydraulic turbine unit is influenced, and the impeller of the hydraulic turbine unit is seriously damaged directly. Meanwhile, the floating box in the existing float blocking equipment is generally round, is made of iron sheet or plastic, and is easy to damage and leak water under the impact of water flow and large-volume floaters; when water flow is turbulent, the buoyancy tank rows are very easy to turn over, the buoyancy tank rows directly cause the failure of the buoyancy tank row floating blocking equipment to block floaters, the normal operation of the hydraulic turbine unit is influenced, and the hydraulic turbine unit is even damaged.

The national intellectual property office discloses in CN203701059U (a hanging grid for a float stopping device, 20140709): the invention relates to the field of water conservancy and hydropower equipment, in particular to a hanging grid used on a float blocking device of the water conservancy and hydropower equipment, and aims to solve the problems that the existing float blocking equipment cannot effectively block floats above and below the water surface and floats with small volume, and the floating equipment is easy to turn over in turbulent water flow. The utility model discloses a hanging grid sets up on the lateral wall of flotation tank, hanging grid includes several reinforcing plates and several grid tray, connects into the fence body between reinforcing plate and the grid tray, and fence body one side is provided with the couple. The utility model discloses a block and float device can effectively intercept the big or small floater of surface of water upper and lower with the hanging grid, can ensure to block the safety of floating the row simultaneously.

However, in the technical scheme, the size of the through hole on the hanging grid is fixed, so that floating objects with small volume can not be effectively intercepted, and the hanging grid with the size corresponding to the through hole needs to be replaced, so that the operation is inconvenient, and time and labor are wasted. Meanwhile, the floating blocking equipment is generally formed by connecting a plurality of floating boxes into a floating box row, and the floating grids are required to be locked on the floating boxes one by one, so that the floating blocking equipment is inconvenient to collect and install.
