Abstract
The utility model relates to a water channel drainage device which solves the problem that an existing drain grating can not intercept and remove dirt, such as mud and stones in a water channel. The water channel drainage device comprises a gate for intercepting water and blocking dirt 1, an overflowing mouth 4 which are arranged at the upper part of a flow channel of the water channel, a dirt deposition bucket 5, a drainage valve 6 which are arranged in a flow channel at the lower part of the gate for intercepting water and blocking dirt, at least one dirt deposition groove 7 transversely positioned in the flow channel, and a drainage valve 8. The utility model has the advantages that flotation dirt can be removed, and deposition dirt, such as mud, stones, etc. can also be removed. The utility model is suitable for rivers, water channels and water passages with a definite drop height. The utility model is especially suitable for removing dirt in a water channel for supplying water in a hydraulic power station.
Description
The utility model relates to the blowdown apparatus of water channel, especially for the power station ditch dirt clearing device that the precipitating type sewage draining passage is arranged of power station water supply water channel.
Existing power station ditch dirt clearing device, trashrack normally is set in water channel, and this trashrack can only be tackled the floating pollutant of removing in the runner, can not tackle the silt of removing in the runner, the shortcoming of stone class dirt and exist, dirt often occurs and stop up the power station hydraulic turbine, cause few generating accident.
Given this, the purpose of this utility model is to provide a kind of can remove floating pollutant, can remove the power station ditch dirt clearing device of dirts such as silt stone again.
The utility model adopts water-trash retaining gate and overfall respectively and adopts dirt sinking bucket and blowoff valve thereof in the bottom of water channel according to the floatation characteristic of floating pollutant and the precipitation characteristic of silt stone on the top of water channel, realize its purpose.And further in the rearmounted runner of dirt sinking bucket, adopt dirt sinking groove and blowoff valve thereof to realize its purpose.
Power station of the present utility model ditch dirt clearing device (referring to accompanying drawing), comprise the water-trash retaining gate (1) and the overfall (4) that are fitted on the water channel, above-mentioned water-trash retaining gate is arranged on the top of runner, the blowoff valve (6) that dirt sinking bucket (5) is arranged in the runner below water-trash retaining gate and be communicated with dirt sinking bucket.
The blowoff valve (8) that at least one dirt sinking groove that is horizontally placed on runner (7) can be arranged in the rearmounted runner of above-mentioned dirt sinking bucket (5) and be communicated with dirt sinking groove.
The bottom connection of above-mentioned blowoff valve (6) and dirt sinking bucket (5), the lateral inclination in the longshore current road, bottom surface of above-mentioned dirt sinking groove (7), above-mentioned blowoff valve (8) joins with the low bottom end of dirt sinking groove (7).
The two ends of above-mentioned water-trash retaining gate (1) are in the setting slideway (3) that is fitted in water channel slidably respectively.
Said structure of the present utility model makes it have following advantage and effect.
One, water-silt retaining gate door of the present utility model, with the overfall structure, owing to be arranged on water channel top, can tackle floating pollutant in the runner with water-trash retaining gate, and then get rid of by overfall and to take out the floating pollutant of interception, and can adjust according to the flow lifting of water channel.
Two, dirt sinking bucket of the present utility model and blowoff valve structure, its dirt sinking bucket can precipitate silt, the stone class dirt in the runner, open the silt and the stone class dirt of blowoff valve energy scavenger precipitation in good time.
Three, dirt sinking groove of the present utility model and blowoff valve structure, in silt stone amount in bigger season and water channel, through dirt sinking bucket is preliminary remove after, can further precipitate the precipitability dirt in the runner, open the dirts such as silt that blowoff valve just can scavenger precipitation.
The utility model is applicable to the river that certain drop is arranged, water channel, the water channel that needs to remove floatability dirt and precipitability dirt, is specially adapted to the water supply water channel in power station.
Below, the utility model is further described to use embodiment and accompanying drawing thereof again.
Brief description of drawings.
Fig. 1 is the structural representation of a kind of power station of the present utility model ditch dirt clearing device.
Fig. 2 is the vertical view of Fig. 1.

Embodiment 1
A kind of power station of the present utility model ditch dirt clearing device, as shown in drawings.Constitute by water-trash retaining gate, dirt sinking bucket, dirt sinking groove etc.
Above-mentioned water-trash retaining gate 1 is made the gate structure of common plate shape, is fitted in the water channel 2, and water channel 2 can be made by common sheet material, and tipping becomes the some of water channel in the slow water section of power station water channel.The setting slideway 3 that common structure is arranged on the top of the biside plate of water channel 2.The two ends of water-trash retaining gate 1 are to be fitted in slidably erect in the slideway 3, and configuration lifting gear (not shown), make its lifting as required.On side plate top, open the overfall 4 that is shaped on common structure near the water channel 2 of the upper reaches side of water-trash retaining gate 1.
Above-mentioned dirt sinking bucket 5 is made common infundibulate, is installed in the below of water-trash retaining gate 1, and becomes one with water channel 2, thereby makes the runner in the water channel become the V font, and makes the top of water-trash retaining gate 1 in the V-shaped flow road.The bottom of dirt sinking bucket 5, tipping has the blowoff valve 6 of common structure.In the rear end of blowoff valve 6 tipping blow-off pipe or blowdown canal (not shown).Thereby constitute the precipitating type sewage draining passage by dirt sinking bucket, blowoff valve.
Above-mentioned dirt sinking groove 7 is in the runner of the postposition side that is arranged on dirt sinking bucket 4 horizontally, can become one structure with the bottom of water channel 2.Dirt sinking groove can have at least one, and present embodiment adopts two dirt sinking grooves.The lateral inclination in the longshore current road, bottom surface of dirt sinking groove.End in the low bottom surface of each dirt sinking groove, tipping has the blowoff valve 8 of common structure.Also can be hinged with blow-off pipe or blowdown canal (not shown) in the rear end of blowoff valve 8.Thereby constitute the precipitating type sewage draining passage by dirt sinking groove, blowoff valve.
Present embodiment can adopt multiple materials such as steel, concrete, masonry to make.
Present embodiment is specially adapted to be installed in the slow water section of power station water supply water channel.Can remove floatability dirt and precipitability dirt in the water channel effectively.
