Abstract
A sawtooth weir notch shape anti-freezing device, comprises sawtooth weir notch, a plurality of floating drum and hydroelectric generator.There is sawtooth a plurality of and that weir notch body becomes one structure at the weir notch body upper shed edge of sawtooth weir notch.The external wall surface of weir notch is around being fixed with a plurality of floating drums.Weir notch body bottom is connected by tapping pipe with hydroelectric generator.The external wall surface of weir notch is simultaneously around being fixed with electric calorifie installation.Electric calorifie installation is connected with hydroelectric generator by cable.Sawtooth weir notch is arranged in the hydraulic structures such as the sluice side that meets water and bubbles through the water column, surface current enter weir notch by the sawtooth concave point of weir notch body upper shed, the current that tapping pipe releases drive hydroelectric generator to generate electricity to electric calorifie installation power supply, thereby make the heating of sawtooth weir notch outer wall prevent sawtooth weir notch, around the water surface is icing.So just can guarantee that the water surface that sluice or hydraulic structure meet water in side certain limit does not freeze, and plays the object of Anti-freezing.
Description
Technical field
The utility model belongs to hydraulic engineering field anti-freezing device in winter, and particularly a kind of sawtooth weir notch shape anti-freezing device can be applicable to the water conservancy project building side that meets water, and prevents that the water surface from freezing before being especially applicable to being arranged on gate.
Background technology
In the northern water conservancy project building side that meets water, all can bear frost action annual winter, and multigelation circulation will cause the destructions such as the freeze thawing of obstructing surface building generation concrete is degraded, protecting building block lycopod is moving, reduced the durability of building.For gate position, the quiet ice pressure causing due to ice sheet expansion can make gate produce distortion, lift, and even produces structural deterioration, causes the consequences such as gate cannot normally open and close, sealing inefficacy.Current conventional Anti-freezing measure, as air-compressing, submersible pump method, heat pipe freeze proofing and the icebreaking method etc. of manually slotting, ubiquity that energy consumption is large, operation is dangerous and the problems such as runtime maintenance difficult.
Utility model content
The purpose of this utility model is to provide a kind of sawtooth weir notch shape anti-freezing device, and by self earial drainage, generating produces clean energy resource for the heating of weir notch wall to this device, simple in structure, safe and reliable.
The technical scheme adopting is:
A sawtooth weir notch shape anti-freezing device, comprises sawtooth weir notch, a plurality of floating drum and hydroelectric generator.
Its technical essential is:
Sawtooth weir notch comprises weir notch body and a plurality of sawtooth, and a plurality of sawtooth are arranged on the edge of weir notch body upper shed, and becomes one structure with weir notch body.
The external wall surface of weir notch is around being fixed with a plurality of floating drums.Weir notch body bottom is connected by tapping pipe with hydroelectric generator.
The external wall surface of weir notch is simultaneously around being fixed with electric calorifie installation.Electric calorifie installation is connected with hydroelectric generator by cable.
Described electric calorifie installation is electrothermal tube or heating wire.Described weir notch body is cuboid.
Described a plurality of sawtooth evenly arrange at the Distances Between Neighboring Edge Points of weir notch body upper shed.
The sawtooth weir notch of this device is arranged in the water conservancy project building such as the sluice side that meets water.Sawtooth weir notch is lifted by floating drum, bubbles through the water column, and surperficial current enter weir notch by the sawtooth concave point of weir notch body upper shed, and by tapping pipe discharged to downstream.At tapping pipe tail end, a hydroelectric generator is installed, the electric energy of generation is supplied with the electric calorifie installation on weir notch body by cable, thereby make the heating of sawtooth weir notch outer wall prevent sawtooth weir notch, around the water surface is icing.Surface water forms current in the process that enters sawtooth weir notch, although flow velocity is unhappy, can also stop sawtooth weir notch to freeze around.So just can guarantee that the water surface that sluice or water conservancy project building meet water in side certain limit does not freeze, and plays the object of Anti-freezing.
Its advantage is:
Water around confluxes to sawtooth weir notch inside and can produce the current of certain flow rate, by self waterpower earial drainage generating, produces clean energy resource for the anti-freezing device of sawtooth weir notch wall heating.
This device can form not icing area at the upstream side of the water conservancy project building such as northern area gate, avoided the direct destruction that winter, the water surface froze to water conservancy project building such as gates, thereby reach the object of Anti-freezing, simple in structure, easy to operate, safe and reliable, operation maintenance amount is little, and utilizes clean energy resource can meet the self-sufficient operation of device.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
embodiment 1
A sawtooth weir notch shape anti-freezing device, comprises sawtooth weir notch 1, a plurality of floating drum 3 and hydroelectric generator 6.
Sawtooth weir notch 1 comprises weir notch body and a plurality of sawtooth 7, and a plurality of sawtooth 7 are arranged on the edge of weir notch body upper shed, and becomes one structure with weir notch body.
The external wall surface of weir notch by bolt around being fixed with a plurality of floating drums 3.Weir notch body bottom is connected by tapping pipe 4 with hydroelectric generator 6.
The external wall surface of weir notch is simultaneously around being fixed with electric calorifie installation 2.Electric calorifie installation 2 is connected with hydroelectric generator 6 by cable 5.
Described electric calorifie installation 2 and hydroelectric generator 6 are known technology, therefore repeated description not.
Electric calorifie installation 2 is electrothermal tube.
A plurality of sawtooth 7 evenly arrange at the Distances Between Neighboring Edge Points of weir notch body upper shed.Described weir notch body is cuboid.
Under the effect of floating drum 3, sawtooth weir notch 1 swims on the water surface.Adjust the bolt of a plurality of floating drums 3, water is evenly flowed in sawtooth weir notch 1 constantly from the concave point of the sawtooth 7 of sawtooth weir notch 1, the water in sawtooth weir notch 1 is entered hydroelectric generator 6 and is entered downstream through hydroelectric generator 6 by tapping pipe 4.
Electric calorifie installation 2 is fixed on sawtooth weir notch 1 wall, and is connected with hydroelectric generator 6 by cable 5.When the water in sawtooth weir notch 1 is flowed through hydroelectric generator 6 continuously through tapping pipe 4, the electric energy that hydroelectric generator 6 produces makes electric calorifie installation 2 heatings, can better play the effect of the water freezing that stops sawtooth weir notch 1 wall.
When water flows into sawtooth weir notch 1 from a plurality of sawtooth 7, at the water surface of sawtooth weir notch 1 surrounding, produce the current of certain flow rate simultaneously, thereby also play the sawtooth weir notch 1 icing effect of the water surface around that stops.
embodiment 2
Embodiment 2 is substantially the same manner as Example 1, and its difference is: electric calorifie installation 2 is heating wire.
