Abstract
The utility model relates to a water fetching equipment which is used for the water supply engineering, comprising a saw tooth canister, a cone, a water collection canister, a water output pipe and a sand removing canister. The inside and the lower part of the sand removing canister are respectively provided with a lateral flow sloping plate provided with a sand removing gallery, a sand removing bucket, etc. When the utility model is used for the water fetching engineering of a river, the utility model can prevent floaters such as grasses, etc. from stopping a water input hole and can effectively remove the large silt to provide guarantee of supplying the water safely. The utility model is reasonable in design, convenient in installation and easy in production.
Description
The utility model relates to a kind of intake equipment that is used for water works engineering.
In the surface water supply engineering that with rivers is the water source, the water intaking head is the equipment of crux very, the good and bad security of operation that directly influences water factory of water intaking head.In recent years because the artificial destruction of natural environment, the climate abnormality, flood happens occasionally.It is long neglected and in disrepair to add the riverbed, factors such as severe water and soil erosion, and the river is some mountain streams particularly, and silt and floating things such as rice, weeds that one to flood season is a large amount of are brought in the river by surface runoff, have caused serious threat for the water intaking of korneforos, the Congjiang.Traditional water intaking head, as oviduct water intaking head, box water intaking head, mushroom-shaped water intaking head, fish shape cover water intaking head etc., water intake mode belongs to aperture or weir flow dual mode more, and its water inlet flow velocity is big, and does not have the function of removing sand.To making floating thing stop up water intaking head inlet opening and water pump vane, electric current is descended, until not taking out water.The grains of sand of high concentration enter water pump and handle structure with water, have quickened the wearing and tearing of impeller, and make the heavy mud of water sedimentation structure be difficult to get rid of, and influence water factory's effluent quality.Can be directed at water factory when serious and stop production, bring loss, make troubles to people's lives to industrial production.
The purpose of this utility model provides a kind of water intaking head that can prevent that floating thing from stopping up and removing sand.
The purpose of this utility model is achieved in that one side with another rectangular thin plate not with holes, one side of a rectangular thin plate of bringing the water hole into is linked by certain angle that constituting longitudinal section is zigzag device.The sawtooth that several are the such knot that joins end to end just constitutes zigzag flap.Make the sawtooth cylinder that section is rectangle or other shape with the zigzag flap again.Link the cone that is made by polygonal panel at an end of sawtooth cylinder (by an end of the plate of not bringing the water hole into of sawtooth), the other end links outlet pipe is installed.The Water collecting tube of tubular.Do not establish the inlet opening on the cone, it is arranged in face of current, is bearing the effect of water conservancy diversion and protection sawtooth.When water intaking, river will change 180 ° and just can flow in the inlet opening later on, and floating thing produces " dead point " (being that movement velocity is zero position) at the sawtooth place, rotate, and constantly revolves with current, is difficult to enter the inlet opening.So just reached and only intake not advance the purpose of floating thing.
The purpose of this utility model can also realize by following measure: install the husky tube of the row that can remove sand between sawtooth cylinder and Water collecting tube, the husky bucket of row is established in the husky tube of row bottom, the inner lateral flow inclined plate that some band flush galleries that are parallel to each other longitudinally are installed of the husky tube of row.Add such swash plate because of arranging in the husky tube, strengthened the effect of removing sand, increased desilting area.The grains of sand are short at plate face sliding distance, and current have lower Reynolds number and higher Fu Luode number between plate, and hydraulics is good.The husky bucket of row can form " suspension sand bed " in addition, utilizes the water velocity of rivers to realize that efficient row automatically is husky.
The utility model is compared with existing water intaking head, can avoid floating thing to stop up bucket portion and water pump vane passage effectively.In addition, the effect of removing sand improves greatly, can no longer build sand trap.Can not only the row of saving beach volleyball mud water institute consuming electric power, and can also alleviate the water pump vane wearing and tearing widely, save capital investment, simultaneously water quality is guaranteed.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Fig. 1 the utility model sectional view
Fig. 2 the utility model sawtooth sectional view
Fig. 3 the utility model lateral view
Fig. 4 the utility model cross section sectional view
Fig. 1, Fig. 2 are an embodiment of the present utility model.1 is sawtooth cylinder among the figure, and 2 is cone, and 3 is Water collecting tube, and 4 is outlet pipe, and 5 for bringing the rectangular slab in water hole into, and 6 for not bringing the rectangular slab in water hole into.Plate 5 and 6 is made sawtooth by certain angle, and the sawtooth that several are such joins end to end and then forms the zigzag flap, four blocks of flaps is assembled into the sawtooth cylinder 1 that the cross section is a rectangle again.One end of sawtooth cylinder links cone 2, and other end joint collection water drum 3 is installed outlet pipe 4 on the Water collecting tube 3.So just make the zigzag water intaking head of anti-grass.
Fig. 3, Fig. 4 are another embodiment of the present utility model.1 is sawtooth cylinder among the figure, and 2 is cone, and 3 is Water collecting tube, and 4 is outlet pipe, and 7 are the husky tube of row, 8 lateral flow inclined plates for the band flush gallery in the husky tube 7 of the row of being installed in longitudinally, and the 9 row's sand for the row of being installed in husky tube 7 bottoms struggle against.This zigzag water intaking head for preventing that floating thing can remove sand again.
The utility model profile can be the tube of rectangular cylinder or other shape, and sawtooth cylinder can be installed in the one or both ends of Water collecting tube, the husky tube of row, and material can adopt steel or stainless steel, and lateral flow inclined plate also can adopt plastic plate etc.Preferably 45 ° of the skewback inclination alpha of sawtooth, water inlet plate with holes is preferably vertical with horizontal plane.The spacing of lateral flow inclined plate is not less than 20mm, and the inclination angle is preferably adopted 60 °, and row Sha Dou adopts 60 ° in the inclination angle.In that just floating thing is many, sand adopts the head of the device that do not remove sand less or in the rivers of husky thin (particle diameter is below 0.1mm).At floating things such as existing weeds, need removing sand again, (directly for more than the 0.1mm, its sand content is less than 5kg/m for the grains of sand
3) rivers in adopt the remove sand water intaking head of device of band.
The utility model is reasonable in design, and is easy for installation, can finish manufacturing in factory.Installation can be adopted fixed according to actual conditions, also can adopt movable.
