Abstract
The utility model relates to the technical field of purification of surface water and the like, in particular to a caisson-type water intaking device for surface water of small-sized water plant. The device is provided with a tank body placed in water and a water intaking system, wherein a small hole is formed on the side surface of the tank body; one end of a water intaking pipe of the water intaking system is placed in the tank body; a back flushing device is connected to the water intaking system and comprises a pipe fitting with a water outlet facing the tank body and a valve device used for controlling water to flow to the pipe fitting from the water intaking pipe; and the tank body is in the shape of a cylinder, and an orifice of the water intaking pipe is placed in the position of two-thirds height of the tank body. The device is free from the influence of vessel sailing, occupies less space, is mainly used as a surrounded grating and the like of a wet well for building a dam, reduces the large investment and the manpower due to the automatic control of desilting, and facilitates the disassembly and the movement.
Description
Technical field
The utility model relates to the purification technics field of surface water etc., especially a kind of water fetching device of surface water caisson type of small-sized water factory.
Background technology
Along with the develop rapidly of industrial and agricultural production, water supply volume is increasing, and water resource is more and more in short supply.For using water wisely and quality classification water supply, some enterprises near rivers and lakes are adopting and are exploiting surface water nearby, by purifier, reach the industrial water use requirement, have reduced cost of production.But existing water fetching device is bulky, and occurs stopping up now the effect of influence water intaking easily.At present most of small-sized water factory of providing for oneself, its intake is equipped with grid, behind the multiple tracks filtering ponds, is entered in the purifier by the water intaking pump.Like this, the intake area occupied is big, and especially near the place of the Changjiang river and amber, in order to resist the impact of stormy waves, the investment of intake is bigger.
The utility model content
The technical problems to be solved in the utility model is: for shortcoming and the deficiency that solves above-mentioned existence, provide a kind of water fetching device of caisson type, build by laying bricks or stones and fetch water after wet-well is introduced surface water again, saved the cost resource.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of water fetching device of caisson type, have the casing and the water intake system that place water, the side of casing offers aperture, intake pipe one end of water intake system places casing, be connected with back purge system on the water intake system, back purge system includes delivery port and faces toward the pipe fitting of casing and the valving that control water is flowed to pipe fitting by intake pipe, fetch water by water intake system, when needing by the by-pass valve control device, water is passed back into casing, because the effect of pressure makes the interior deposit of casing be rushed out casing, reaches the effect of cleaning.
Further, in order to make the current in the casing even, realize the effect of flushing easily, casing is cylindrical.
In order to make foreign material in the casing etc. can not enter immediately in the intake pipe, the mouth of pipe of intake pipe places 2/3 place of box height.
In order to resist stormy waves, can build wet-well by laying bricks or stones, after being introduced, surface water fetches water by the water fetching device of a kind of caisson type of the present invention again.
The beneficial effects of the utility model are, the water fetching device of a kind of caisson type of the present utility model owing to sink under water, is not subjected to the influence of ship navigation, and floor space is little; Mainly be on the river course, to do dam block wet-well to enclose grid etc., reduced great amount of investment; Owing to be to control desilting automatically, reduced the labour; Convenient disassembly is convenient to move.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Among the figure 1, casing, 2, water intake system, 2-1, intake pipe, 3-1, pipe fitting, 3-2, valving.
The specific embodiment
In conjunction with the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
The water fetching device of a kind of caisson type of preferred forms as shown in Figure 1, have the cylindrical box 1 and the water intake system 2 that place water, the side of casing 1 offers aperture, intake pipe 2-1 one end of water intake system 2 places casing 1, be connected with back purge system on the water intake system 2, back purge system includes an end and places the pipe fitting 3-1 of casing 1 and the valving 3-2 that control water is flowed to pipe fitting 3-1 by intake pipe 2-1, and the mouth of pipe of intake pipe 2-1 places 2/3 place of casing 1 height.
When the utility model is implemented, earlier casing 1 is designed conglobate two inner chambers that have, around casing 1, bore full aperture then, casing 1 submerged is played the effect that is equivalent to grid.Two intake pipe 2-1 are inserted respectively in casing 1A inner chamber and the B inner chamber.After water entered in the casing 1 by casing 1 aperture, intake pipe 2-1 inserted 2/3 place of casing 1 height, even foreign material such as mud are arranged like this, also can not enter in the pipe immediately.Make the water in the intake pipe 2-1 flow back to casing 1 by control,, reached the effect of cleaning casing 1 because the effect of pressure makes flow velocity very big by pipe fitting 3-1 to valving 3-2.
Following according to shown in Figure 1, be the concrete valve control action list of implementing backwash:
By each valve being carried out the control of opening and closing, realize that water is back to casing 1, the purpose that casing 1 is cleaned.Or else the related personnel can depart from fully in the scope of present technique and change flexibly or revise, and makes the water intake system 2 of purifier reach required maximum water withdrawal.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.
