Abstract
A device used for intercepting the filth of an intake canal of a nuclear power plant consists of a wire cable, a filth intercepting net and a mechanical lifter. The wire cable is arranged above the surface of the sea. Both ends of the wire cable are fixed with a bracket arranged on a fixed pile foundation platform on land and the wire cable is connected with the mechanical lifter. A filth intercepting net is suspended on the wire cable and the lower part of the filth intercepting net is fixed on a seabed cable chain and a concrete anchor. The device used for intercepting the filth of the intake canal of the nuclear power plant has the advantages and positive benefits as follows: 1. the device has a good effect of intercepting the filth; 2. the device is quick and easy to be operated and can save operation cost; 3. the whole filth intercepting net can fall into water to ensure that a dredger can pass through smoothly; and the lifting operation is time saving and labor saving; 4. a whole filth intercepting system can bear stronger impact of wind and wave, thus ensuring the safe and reliable working of the filth intercepting system and the safety of a see wall; 5. construction cost is low and maintenance load is small.
Description
Technical field:
The utility model relates to a kind of device of tackling seawater impurity, particularly a kind of device that is used to tackle the nuclear plant water intaking channel dirt.
Background technology:
Along with day being becoming tight of international energy supply conditions, for the quick growth of satisfying electricity needs with protect environment better, obtained fast development as the nuclear power of clean energy resource.As everyone knows, the nuclear power station operation be unable to do without the water source, and the used in nuclear power station water yield is huge, and water resource system is of crucial importance to the normal operation of nuclear power station.But because the China's Coastal Areas marine environmental pollution is serious day by day, occur some seasons wheat straw stalk, sea-plant as: floating pollutants such as laver, algae etc. and travel life rubbish pour in the nuclear plant water intaking open channel, have a strong impact on the nuclear power station operation, cause and normally to fetch water, the safe operation of nuclear power station has been constituted serious threat.At present, the nuclear power station that has adopts buoyancy tank to block dirt, but it is relatively poor to block dirty effect, and the stability of capacity of anti-storm, work is not high.
Summary of the invention:
The purpose of this utility model just is to overcome above-mentioned the deficiencies in the prior art, and provide a kind of device that is used to tackle the nuclear plant water intaking channel dirt, this device can be tackled the dirt in the seawater effectively, and utilizes mechanical elevating mechanism not influence the turnover of boats and ships.
The technical solution of the utility model is: a kind of device that is used to tackle the nuclear plant water intaking channel dirt, it is characterized in that: form by wire rope, garbage barrier net and mechanical lifting gear, steel wire rope overhead is in the sea, its two ends and land spud pile based platform upper bracket are fixed, and wire rope is connected with mechanical lifting gear; Garbage barrier net is suspended on the wire rope, and its underpart and seabed are fixed with anchor chain and concrete anchor.
The utility model can also adopt following technical measures:
Above-mentioned garbage barrier net is " people " font by two sections garbage barrier nets and is laid in the outside, nuclear plant water intaking open channel entrance, nets 90 ° of mutual angles for two sections.
Above-mentioned garbage barrier net is made up of one-level grid and secondary net sheet, and secondary net sheet hangs on the one-level grid.
Movable support frame is equipped with at above-mentioned garbage barrier net middle part.
Above-mentioned mechanical lifting gear adopts hand winch.
The utlity model has following advantage and good effect:
1, this trash block system relies on wire rope and ground chain linked network to block dirt, and wire rope and linked network hang and exceed on the water surface, reaches more greatly under the situation that a large amount of dirts pour at stormy waves, can stop effectively that also dirt crosses from water surface following sea, blocks dirty effective.
2, be laid in the outside, nuclear plant water intaking open channel entrance because garbage barrier net is " people " font by two sections garbage barrier nets, net 90 ° of mutual angles for two sections.Therefore can make full use of the recoil brush effect of reciprocal ocean current, the minimizing dirt adheres on garbage barrier net with dirt to be piled up at the canal mouth.
3, because garbage barrier net is made up of one-level grid and several secondary net sheets, secondary net sheet hangs on the one-level grid.The removing contamination or need not put in order net when damaging and change of net, only need part secondary net sheet cleared up and more the draping sheet get final product, operation is convenient rapidly, the saving running cost.
4, be connected with mechanical elevating mechanism on the wire rope, when the water intaking open channel needed desilting, whole net can descend in water, guaranteed that dredge boat passes through smoothly.And descending operation is laborsaving, save time.
5, adopt movable supporting in the middle of the per pass garbage barrier net, its advantage is: the built on stilts wire rope amount of deflection of garbage barrier net is little, and support height reduces, and steel wire rope tension is little, can adopt little load winch, and improves capacity of anti-storm; When garbage barrier net descended in water, the water surface can provide about 40 meters channel spans, has guaranteed passing through of boats and ships preferably.
6, because wire rope two ends and spud pile based platform upper bracket hinged securement, the following chain and the anchoring mutually of seabed concrete anchor of adopting of garbage barrier net, therefore, strengthened the stability of wire rope and garbage barrier net, make whole trash block system can bear bigger storm impact, guarantee that it is safe and reliable, guarantee the safety of mole.
7, construction cost is low, and maintenance workload is little.

The specific embodiment:
A kind of device that is used to tackle the nuclear plant water intaking channel dirt is made up of hand winch 1, wire rope 3 and garbage barrier net.In order to make full use of the recoil brush effect of reciprocal ocean current, reducing dirt adheres on garbage barrier net, avoid dirt to pile up at the canal mouth, the garbage barrier net of this device is " people " font by left and right two sections garbage barrier nets and is laid in the outside, nuclear plant water intaking open channel entrance, and two sections mutual angles of garbage barrier net are 90 °.It is convenient, fast for garbage barrier net is changed, and cost saving, the garbage barrier net of native system is made up of one-level grid 4 and secondary net sheet 5, and secondary net sheet hangs on the one-level grid, therefore the removing contamination or need not put in order net when damaging and change of net, only need part secondary net sheet cleared up and more the draping sheet get final product.In order to improve the capacity of anti-storm of whole system, guarantee passing through of boats and ships, at the garbage barrier net middle part movable support frame 7 is housed.In order to strengthen the stability of wire rope and garbage barrier net, make whole trash block system can bear bigger storm impact, guarantee that it is safe and reliable, guarantee the safety of mole, with steel wire rope overhead in the sea, its two ends and land spud pile based platform upper bracket 2,6,7 hinged securement, and wire rope is connected with hand winch 1,8; And garbage barrier net is suspended on the wire rope, its underpart and seabed anchor chain 9 and concrete anchor anchoring mutually.
