Description of the drawings
The invention will be further described below in conjunction with the accompanying drawings.
Fig. 1 is the structure diagram for cutting dirty net system of the embodiment of the present invention 1.
Fig. 2 is the structure diagram for cutting dirty net of the embodiment of the present invention 1.
Enlarged diagrams of the Fig. 3 for A parts in Fig. 2 of the embodiment of the present invention 1.
Fig. 4 is the structure diagram for cutting dirty net of the embodiment of the present invention 2.
Embodiment includes with the noun that Figure of description is related to and label：Cut dirty net 1, pier 2, frame net 3, facilities network 4,
Hollow tube 5, through-hole 6.
Specific embodiment
Embodiment 1：
Referring to figs. 1 to shown in 3, Fig. 1 is the structure diagram for cutting dirty net system for water intake of power plant open channel, W arrows in figure
The direction instruction water (flow) direction of head.Fig. 2 is the structure diagram for cutting dirty net.Fig. 3 is the enlarged diagram of A parts in Fig. 2.
With reference to shown in Fig. 1, include two layers of section dirty net 1 being located in open channel for 1 system of dirty net of cutting of water intake of power plant open channel,
Comparison individual layer web frame can preferably intercept ocean tiny organism, so as to ensure power plant's low-temperature receiver safety.It is different according to flow velocity, two layers
The distance between dirty net 1 is cut as 0.2m~1.0m, when flow rate of water flow is higher, larger section 1 spacing of dirty net should be set, prevent office
Portion's resistance is excessive.The two sides that dirty net 1 is fixed on open channel by pier 2 are cut, dirty net 1 is cut and is removably couplable on pier 2.Pier
2 are equipped with sliding slot, cut dirty net 1 and are slidably connected on pier 2 by sliding slot.Dirty net 1 and open-channel flow direction oblique are cut,
Oblique angles α is 30 °~60 °, and preferred angle is 45 ° in the present embodiment, cuts dirty net 1 and water (flow) direction oblique, it is possible to increase cut
The forced area of dirty net 1 weakens flow to a section impact for dirty net 1, makes section dirty net 1 safer durable.The height for cutting dirty net 1 is water
Deep 1/4~3/4, preferred scheme be to cut dirt 1 height of net to be approximately equal to the 1/2 of the depth of water in the present embodiment.Flow and open channel bottom surface
Between there are larger frictional force, the flow velocity for making the water surface is higher, and ocean tiny organism is distributed in the bottom more, therefore will cut a dirty net
1 height is set as the 1/2 of the depth of water.
It is a kind of to cut dirty net equipped with 5 structure of hollow tube with reference to shown in Fig. 2 to 3, including by interlaced 5 structure of hollow tube
Into frame net 3, be uniformly provided with several through-holes 6 on the tube wall of hollow tube 5.The material of hollow tube 5 is elastoplastic, can be with wave
Reciprocating motion and reciprocating expansion shrink and jet stream are formed in through-hole 6 in open channel, thus the attachment on Impact Foundation net 4,
Achieve the effect that self-cleaning.With reference to practical experience, when 3 port size of frame net is 0.4m × 0.4m, manufacture cost is higher, but
Stronger water impact under common situations can be coped with.When 3 port size of frame net be 0.8m × 0.8m when, manufacture cost compared with
It is low, but coped with most of streamflow regime in common situations enough.The size in 4 aperture of facilities network for 0.010m × 0.010m~
0.020m × 0.020m, the smaller then retaining power of port size is stronger, but the impact that section dirty net is born is bigger, needs according to reality
Situation is selected.3 aperture of the present embodiment middle frame net is preferably dimensioned to be 0.6m × 0.6m, and 4 aperture of facilities network is preferably dimensioned to be
0.015m × 0.015m, at this time its manufacture moderate cost, structural strength and retaining power are preferable.The nominal diameter of hollow tube 5 is
15mm~25mm selects the caliber of bigger to be conducive to the structural strength that enhancing cuts dirty net, and manufacture cost is higher.The public affairs of through-hole 6
Claim a diameter of 1mm~3mm, the aperture of bigger is selected to be conducive to anti-clogging, and smaller aperture is selected to be easier the shape at through-hole 6
Into high pressure water flow.5 nominal diameter of preferred hollow tube is 20mm in the present embodiment, and 6 nominal diameter of through-hole is 2mm, is manufactured at this time
Moderate cost, structural strength, anti-clogging ability and self-purification capacity are preferable.
In the marine growth outbreak period, conductive steel wire can be added on frame net according to actual needs, by conductive steel wire
Be powered, so as to expel small marine organisms, can be improved in the marine growth outbreak period cut dirty net from net effect.It also can be according to practical need
Conductive exothermal steel wire is added on frame net, by being powered on conductive exothermal steel wire, so as to improve the temperature for cutting dirty wire side
And expel small marine organisms, can be improved in the marine growth outbreak period cut dirty net from net effect.
Cut the self-cleaning method one of dirty net：Hollow tube is accessed into high-pressure hydraulic pump, high pressure water is injected into hollow tube and in through-hole
Place forms jet stream, can remove the attachment on the tamper and facilities network in through-hole, makes to cut dirty net self-cleaning.
Cut the self-cleaning method two of dirty net：The biocides such as injection order acid sodium into hollow tube, so as to reduce biological attachment power,
Make to cut dirty net self-cleaning.
Embodiment 2：
It is a kind of to cut dirty net equipped with hollow tubular structure with reference to shown in Fig. 4, including interlaced hollow tube 5, hollow tube
Tube wall is equipped with several through-holes 6, and the material of hollow tube 5 is elastoplastic, and the interlaced formation of hollow tube 5 has the function of to cut dirt
Facilities network.Section dirty net self-cleaning method of the present embodiment is same as Example 1.
Equivalent alternative solution is each fallen in protection scope of the present invention below：
Hollow tube is by the different fractions distribution such as parallel, oblique, bending or irregular shape on facilities network.
Hollow tube is covered, and set on the tube wall of hollow tube on flexible facilities network or other wire sides for having the function of to cut dirt
There are several through-holes.
Embodiments of the present invention are explained in detail above in conjunction with attached drawing, but the present invention is not limited to above-mentioned embodiment party
Formula, can also be before present inventive concept not be departed from the knowledge having in the technical field those of ordinary skill
Put that various changes can be made.
