Description

Novel floating block capable of preventing floating objects from being retained

Technical Field

The utility model relates to a water conservancy water and electricity technical field. More particularly, the utility model relates to a novel block row of floating that can prevent that floater is detained.

Background

The entrance of the intake canal of the hydro-junction power station is usually provided with a floating dam which blocks the floating objects and guides the floating objects to the front of the sluice gate, and the floating objects are drained through the sluice gate. However, under the condition of small warehousing flow, the incoming water is used for generating electricity, the sluice gate is not opened or the water is not abandoned, the included angle between the water flow direction and the floating dam is large when the power station conducts water diversion, and floating objects are retained on the upstream surface of the floating dam. Or due to the impact of the water flow, the pressure of the water flow acts on the float blocking row, so that the float blocking row slowly forms an arc shape which is concave inwards towards the water surface, and the floating objects are slowly accumulated at the concave position of the float blocking row and cannot be discharged. The water blocking effect can be generated after too many floating objects are retained on the float blocking row, the water surface of a water inlet channel area of a hydroelectric power plant at the rear side of the float blocking row is reduced, and the head loss influences the power generation efficiency of the power plant. At present, floaters are basically cleaned by a cleaning ship or a crane grab bucket at the top of a dam through manual machinery, so that manpower and material resources are wasted, and the cleaning efficiency is low.

As shown in fig. 1, the utility model provides a novel block floating row capable of preventing floating objects from being detained, which comprises:

the floating gate structure comprises a floating pipe 1, two ends of the floating pipe 1 are connected to two buoys 2 which are respectively arranged close to a shore 3 and a drain gate 4, the floating pipe 1 is a hollow pipe with two closed ends, the floating pipe 1 floats on the water surface, a plurality of open holes are arranged at intervals along the upstream surface in the length direction of the floating pipe 1, the floating pipe is obliquely downwards arranged towards the drain gate 4, and the open holes are positioned on the water surface;

and the high-pressure pump is communicated with one end of the floating pipe 1 and is used for introducing high-pressure substances into the floating pipe 1.

In the technical scheme, the hydroelectric power plant 6 is arranged between the shore 3 and the sluice gate 4, the buoy 2 is of a structure capable of floating up and down along with the water surface, the buoy 2 is in floating connection through pier columns arranged at the positions, close to the sluice gate 4, of the shore 3 and the hydroelectric power plant 6, so that only up-and-down floating is realized, a small part of the traditional float blocking row 5 mentioned in the background technology is below the water surface, the large part of the traditional float blocking row is above the water surface, and the buoy 2 enables the float blocking row to always float on the water surface to block floats. The technical scheme completely replaces the traditional float interception row 5 by the floating pipe 1 which can float on the water surface to form a new float interception row. Through starting the high-pressure pump, always through high-pressure material to the inside of pipe 1 that floats, high-pressure material blows off through the opening on the pipe 1 that floats to blow away the accumulational floater on the pipe 1 that floats, remove along pipe 1 that floats downstream sluice 4, through sluice 4 discharge floater, avoid the floater to be detained, can realize floating the interval of pipe 1 interior high-pressure material and blow or directly blow through controlling the high-pressure pump. The uppermost large arrow in the figure indicates the direction of water flow, while the plurality of small arrows provided on the float pipe 1 are the oblique directions in which the holes are provided, i.e., the directions in which the final high-pressure substances are blown out.

In another technical scheme, the high-pressure pump is a high-pressure water pump or a high-pressure air pump, and can respectively blow out high-pressure water or high-pressure air, so that the floating objects can be blown away and are not accumulated on the float blocking row.

In another embodiment, the high-pressure pump is arranged on the buoy 2 close to the shore 3 or on the shore 3.
