Detailed Description
Referring to fig. 1 to 3, the drinking water reservoir water quality guarantee device that this embodiment provided includes the filter unit that a plurality of set up one by one, and every filter unit includes flotation device 1, filter screen 2 and the fixing base 3 that top-down set up, is provided with first connecting piece 4 on fixing base 3, and flotation device 1 is connected with first connecting piece 4 through wire rope 5, is provided with locating lever 6 at flotation device 1's both ends about. When laying the filter unit, the fixed base 3 is lowered to the water bottom by means of the wire rope 5. The steel wire rope 5 has high strength, so that the floating device 1 can be positioned, and when the water flow is large, the middle part of the floating device 1 cannot be deformed due to the impact of the water flow. The flotation device 1 is fitted over the positioning bar 6 by means of a first ring (not shown in the figure). The upper end of the filter screen 2 is fixed on the floating device 1, and the lower end of the filter screen 2 is fixed on the fixed seat 3. The floating device 1 comprises a plurality of oil enclosing grids 11, the oil enclosing grids 11 are sequentially connected to form a chain structure, and the oil enclosing grids 11 positioned at the left end part and the right end part of the chain structure are sleeved on the positioning rod 6 through first rings. The oil fence 11 can absorb oil stains floating on the water surface. The filter screen 2 is made by combining geotextile and nylon net, and the geotextile and the nylon net are sewed together to make the filter screen 2. The filter screen 2 thus produced has a higher strength and is less prone to breakage. The shape of the filter screen 2 is rectangular, so that the effective filtering area can be increased, and a better filtering effect is achieved. Two right angles at the upper end of the filter screen 2 are provided with second circular rings (not shown in the figure), and the second circular rings are sleeved on the positioning rods 6. When the floating device 1 is lifted upwards, the filter screen 2 is driven to be lifted upwards, and the filter screen 2 slides upwards along the positioning rod 6 through the second circular ring. In each filter unit, the quantity of fixing base 3 is more than three, and fixing base 3 sets gradually along the lower extreme of filter screen 2. A second connecting piece (not shown in the figure) is arranged on the fixed seat 3, and the lower end of the filter screen 2 is fixed on the second connecting piece. The first connecting piece 4 and the second connecting piece are both hooks.
In this embodiment, the floating device 1 floats above the water line 8, the filter screen 2 hangs in the water body, the fixing seat 3 is arranged at the bottom of the reservoir, and the upper end of the filter screen 2 is fixed on the floating device 1. The lower end of the filter screen 2 is fixed on the fixed seat 3 through the hook, and the width of the filter screen 2 is slightly larger than the depth of water of the reservoir, so that the filter screen 2 is in a slightly bent state in water and is not completely straightened. When the water level in the reservoir rises, the floating device 1 rises upwards, slides upwards along the positioning rod 6 through the first circular ring, drives the filter screen 2 to rise upwards, and at the moment, the filter screen 2 is straightened and hangs in the water, and the steel wire rope 5 is also tightened. When the water level in the reservoir drops in dry seasons, the floating device 1 drops downwards, the first circular ring slides downwards along the positioning rod 6 to drive the filter screen 2 to droop, at the moment, the filter screen 2 changes from a straight state to a slightly bent state, and the steel wire rope 5 changes from a tight state to a loose state. By reserving a part of the filter screen 2 in the water body at the lower end of the filter screen 2, when the water level of the reservoir rises and the filter screen 2 is lifted upwards, the part of the filter screen 2 reserved in the water body is straightened, so that the filter screen 2 can also ensure that all the water body parts in the reservoir can be covered even if the water level rises. Therefore, no matter the water level in the reservoir rises or falls, the filter screen 2 can ensure that all water body parts in the reservoir can be covered, and the effect of filtering impurities in the water body is achieved to the maximum extent.
In this embodiment, in each filter unit, the floating device 1 floats on the water surface, the filter screen 2 is suspended in the water body, the fixing base 3 is arranged at the bottom of the reservoir, the upper end of the filter screen 2 is fixed on the floating device 1, and the lower end is fixed on the fixing base 3. The sewage flowing into the reservoir from the cofferdam 9 is filtered by a plurality of filtering units. The filter screen 2 can filter the silt of aquatic, and flotation device 1 can adsorb the greasy dirt that floats on the surface of water, reaches the purpose of cleaing away the pollutant in the water better for the quality of water of putting in storage is cleaner clear. However, a single filtering unit may not be able to completely adsorb the pollutants in the water body, so a plurality of filtering units need to be arranged, and then the plurality of filtering units are arranged one by one, so that the pollutants in the water body stored in the storage can be removed to the maximum extent.
In the embodiment, in any two adjacent filter units, the distance between one filter screen 2 and the other filter screen 2 is 5-10 m. The filter screen 2 is made of a combination of geotextile and nylon net. The parameters of the geotextile are selected as follows:
the width is 6m, so that the number of splicing seams of the geotextile in the vertical direction can be reduced;
the equivalent aperture is in the range of 0.1 mm-0.2 mm, and the equivalent aperture is the maximum apparent aperture of the geotextile;
vertical permeability coefficient KV＞＝5×10-1cm/s；
Breaking strength ═ 30 KN/m;
tear strength > -. 5 KN.
On the basis of meeting the parameters, the geotextile can also be replaced by terylene, polypropylene fiber, chinlon, vinylon, polyethylene fiber and mixed fiber materials thereof.
Referring to fig. 2 and 4, in each filter unit, the number of the positioning rods 6 is two, and support rods 7 are provided on both left and right sides of any one of the positioning rods 6. The positioning rod 6 and the supporting rod 7 are inserted into the bottom of the reservoir. The support rod 7 plays a supporting role for the positioning rod 6, and the positioning rod 6 is prevented from swinging left and right. Thus, the stability of the whole filtering unit in the water body can be ensured.
In this embodiment, the fixed base 3 is a concrete block with a specification of 30cm × 30cm × 30 cm. In the process of laying the filter unit, the positioning rod 6, the support rod 7, and the floating device 1 are first laid. The concrete block is then sunk to the water bottom by means of the steel wire 5 and then laid by divers. Because the unscheduled flood discharge in upstream river course can cause the impact to the filter unit, and water quality is relatively poor in the reservoir simultaneously, therefore the filter unit needs often to be changed, and the change cycle is 6 months/time.
While the invention has been shown and described with reference to the present embodiments and preferred versions thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
