Description
Technical field
This utility model relates to water intake engineering field, is specifically related to a kind of water-fetching head and cleans device.
Background technology
In water intake engineering field, water-fetching head is widely present, and generally it refers to the water inlet portion of intake strucure at riverbed.Generally; water-fetching head is the first facility that river (river, lake, sea etc.) water flows into water intake pumping station; in order to preferably filter river (river, lake, sea etc.) water; the grid of filtration usually can be provided with, to prevent sand grains in water, foreign material etc. from entering in water pump with current at water-fetching head.But after water-fetching head longtime running, the device such as grid in water-fetching head can be wound around by foreign material etc., blockage problem occurs, causes water withdrawal to reduce.Water-fetching head is as one of the important component part of water intake engineering project, and how it cleans is to fail one of technical barrier of effectively solving always.
Utility model content
The purpose of this utility model is to provide one can solve the problems referred to above, it is possible to realize automatically cleaning the device of water-fetching head.
The technical scheme that this utility model provides is:
A kind of reverse automatic clearing apparatus of water-fetching head, including water intake pumping station, water intake pumping station connects the first regulation valve and the second regulation valve, first regulation valve connects the first water pump, second regulation valve connects the second water pump, first water pump connects the first water-fetching head, the first grid it is provided with in first water-fetching head, second water pump connects the second water-fetching head, the second grid it is provided with in second water-fetching head, it is directly connected to first between described first water-fetching head and water intake pumping station and has directly regulated valve, it is directly connected to second between described second water-fetching head and water intake pumping station and has directly regulated valve.
This utility model devises 2 water-fetching heads, wherein 1 water-fetching head blocks, the units such as other 1 water-fetching head, water pump, regulation valve or structure can be utilized to carry out the most automatically cleaning to it, to go out the foreign material etc. on devices such as being wrapped in grid, periodically can be carried out 2 water-fetching heads, cleaning performance is more preferable the most automatically.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that this utility model uses view one.
Fig. 3 is that this utility model uses view two.
Detailed description of the invention
With detailed description of the invention, this utility model is described in detail below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of reverse automatic clearing apparatus of water-fetching head, including water intake pumping station 1, water intake pumping station 1 connects the first regulation valve 2 and the second regulation valve 11, first regulation valve 2 connects the first water pump 4, second regulation valve 11 connects the second water pump 9, first water pump 4 connects the first water-fetching head 5, the first grid 6 it is provided with in first water-fetching head 5, second water pump 9 connects the second water-fetching head 7, the second grid 8 it is provided with in second water-fetching head 7, it is directly connected to first between described first water-fetching head 5 and water intake pumping station 1 and has directly regulated valve 3, it is directly connected to second between described second water-fetching head 7 and water intake pumping station 1 and has directly regulated valve 10.
This device devises 2 water-fetching heads altogether: the first water-fetching head 5 and 7,2 water-fetching heads of the second water-fetching head can use simultaneously, it is possible to the most standby.As a example by the first water-fetching head 5, work process when water intake system is normally fetched water is: closes first and directly regulates valve 3, run the first water pump 4, river (river, lake, sea etc.) water will regulate valve 2 by first grid the 6, first water pump 4, first being installed in the first water-fetching head 5 and flow in water intake pumping station 1, and whole water intaking process is accomplished.
If the first water-fetching head 5 blocks, see Fig. 2, solid line represents that current can pass through, dotted line represents that current cannot pass through, the operation principle of the reverse auto-cleaning method of water-fetching head is: close the first regulation valve 2, first water pump 4 and second directly regulates valve 10, open first and directly regulate valve 3 and the second regulation valve 11, run the second water pump 9, (river, river, lake, sea etc.) water runs past the second grid 8 being installed in the second water-fetching head 7, and second water pump 9, second regulation valve 11, water intake pumping station 1, first directly regulates valve 3, Zhongdao the first water-fetching head 5, first grid 6 is carried out.After automatically having cleaned, close the second water pump 9, second directly regulation valve 3 and second and directly regulate valve 10, open the first regulation valve 2 and the second regulation valve 11 so that water intake system restores to the original state, so automatically having cleaned the first water-fetching head 5.
In like manner, if the second water-fetching head 7 blocks, see Fig. 3, solid line represents that current can pass through, dotted line represents that current cannot pass through, the operation principle of auto-cleaning method is: closes first and directly regulates valve 3, second water pump 9 and the second regulation valve 11, open the first regulation valve 2, first water pump 4 and second directly regulates valve 10, run the first water pump 4, (river, river, lake, sea etc.) water runs past and is installed on the first grid 6 in the first water-fetching head 5, and first water pump 4, first regulation valve 2, water intake pumping station 1, second directly regulates valve 10, Zhongdao the second water-fetching head 7, second grid 8 is carried out.After automatically having cleaned, close the first water pump 4, first directly regulation valve 3 and second and directly regulate valve 10, open the first regulation valve 2 and the second regulation valve 11 so that water intake system restores to the original state, so automatically having cleaned the second water-fetching head 7.
Advantage of the present utility model: the water-fetching head in tradition water intake engineering project is improved by (1), devise 2 water-fetching heads, 2 water-fetching heads can be arranged apart, it is arranged at diverse location, 2 water-fetching heads can enable simultaneously, also can be the most standby, it can be ensured that whole water intake system water withdrawal is sufficient.(2) wherein 1 water-fetching head blocks, the units such as other 1 water-fetching head, water pump, regulation valve or structure can be utilized to carry out the most automatically cleaning to it, to go out the foreign material etc. on devices such as being wrapped in grid, periodically can be carried out 2 water-fetching heads, cleaning performance is more preferable the most automatically.
