Abstract
A kind of automatic fishing device of the convergence of nuclear power station open channel water intaking channel biology and sundries, comprising: the filter assemblies being obliquely installed are moved to specified region for the object in filter sewage and by the object；Transfer assembly, for transmitting the object for being moved to the specified region by the filter assemblies；Component is salvaged, is arranged independently of one another with the filter assemblies, for salvaging the object transmitted by the transfer assembly.The invention has the advantages that can be outside workshop under the conditions of, be not necessarily to manual intervention, realize in continuous filter water source biology and sundries, pull out and shift；It is especially able to solve traditional scheme and is not available manual cleaning in bad weather and sea situation, due to security reason the net interceptor the case where, avoid nuclear power station cold source system from blocking, the safe operation of nuclear power station is caused to be affected.
Description
Technical field
The invention belongs to block dirty fishing operation field in water process, in particular to a kind of nuclear power station open channel water intaking channel convergence life
The automatic fishing device of object and sundries.
Background technique
It under the conditions of the water intaking of nuclear power station open channel, is mostly blocked now using multiple tracks, cooperates coarse rack, fine fack and drum in workshop
Net filtration device, blocks dirt by different level, and pre- anti-biological cause calamity, sundries intrusion cause the accidents such as shutdown to occur.But domestic outer core
Power station, which still has, repeatedly there is stopping state, and each side has successively put into a large amount of man power and material and studied, and achieves certain
Effect.
Existing net type and disposition structure have substantially met daily demand, and the operation in part power station tends towards stability.The life stopped
Object and sundries have auxiliary facility salvaging in workshop, usually require manual cleaning outside workshop.Power plant has been set up stable contract
Trade caravan 5 carries out operation.The automatic cleaning apparatus at some unit research network bottoms reduces labor intensity to substitute manual cleaning,
But there has been no mature application reports.In the case that when weather condition is severe, especially the biological maximum probability such as Haiti melon is broken out, do
Less than timely cleaning, once excessive intercept, it may cause arresting net fracture, cause hang-up, have corresponding case and occur.
Summary of the invention
The object of the present invention is to provide a kind of automatic fishing device of nuclear power station open channel water intaking channel convergence biology and sundries, solutions
Influence when certainly the sundries such as planktonic organism and rubbish are broken out to water intake system is ensured in bad weather and sea situation complex condition
The safe operation of nuclear power cold source.
The present invention is using drainage and salvages function respectively with different functional component realizations and spatially arranged apart, system
The strategy of " dividing and rule " can be taken with continuous operation, water filtering and sundries are fished for function and separated.
The technical scheme is that
A kind of automatic fishing device of the convergence of nuclear power station open channel water intaking channel biology and sundries, including tilting rigid filter net
(2) fishing device and at net bottom；Tilting rigid filter net is core of the invention device, is responsible for filtering water, at net bottom
Fishing device (3) be responsible for the sundries after tilting rigid filter net filtration is salvaged into the water surface and is pooled to fixed position (11),
Drainage was left for using.Rigid filter net (2) is fixed in water intaking channel (1), in a certain angle with water (flow) direction, and the angle is big
In 25 degree but less than 35 ° angles；(9) rigid filter net (2) is responsible for filtering sea, and sundries (4) is pooled to specified fixation
Position (11).Long enough is arranged in rigid filter net (2), is greater than high-tide level.The discharge area of rigid filter net (2) is sufficiently large,
Even in Partial Blocking, moreover it is possible to guarantee effective water filtering function.Due to rigid filter net (2) direction and flow to angle
(9) relatively small, water flow tangential velocity (7) is more greater than normal direction rate (8), and sundries (4) is in rigid filter under water impact
Sliding is easy on net (2) surface and is not easy to stop blocking；Fishing device (3) at net bottom is raw by Marine Planktonic by continuous operation
The salvagings such as object, sundries (4) ashore fix position (11).
Halomereid, sundries are pooled to automatic salvaging region by ocean current.It, will by the network structure that turns continuously run
Object mentions from water and is transported to the water surface, need to meet small marine growth simultaneously, sundries (class containing bamboo pole) proposes fortune demand；It mentions to platform
After upper, conveyer belt as needed is transported to harbour, platform；Structure is salvaged using floating, to adapt to higher tidal range, in attached drawing
(3) shown in,
The invention has the advantages that can be outside workshop under the conditions of, be not necessarily to manual intervention, realize continuous filter water source
Middle biology and sundries, pull out and shift；Especially be able to solve traditional scheme in bad weather and sea situation, due to security reason
Manual cleaning is not available the net interceptor the case where, avoids nuclear power station cold source system from blocking, leads to the safe operation of nuclear power station
It is affected.

Specific embodiment
Specific embodiments of the present invention are described in detail below in conjunction with technical solution and attached drawing.
Associated materials: antifouling sea bronze net or copper coating steel mesh；Steel skeleton；Antifouling paint；Pile foundation support table.
Water channel flux: Φ；Water channel section: S
Web area: Snet；Mesh size: L
It is inserted into coefficient: η；Strainer flux: Φ net
Effective filtration area: Se；
Floating material is equivalent by flow area: So
Floating material is hampered stress: Fo；Filter screen water flow angle: α
Water velocity: V；Water flow normal velocity: V ⊥
Water flow tangential velocity: V ∥
Design object:
V ∥ > > V ⊥；Se > > S；
Target marine growth and sundries cannot pass through filter screen；
Target marine growth and sundries are easy along net sliding.
The filter assemblies being obliquely installed are moved to specified region for the object in filter sewage and by the object；Incline
The filter assemblies being tiltedly arranged, design water (flow) direction and filter screen angle, mesh size, it is ensured that there are surpluses for strainer flux, and really
It protects and takes main sundries to Nesting Zone.Strainer is as unit of suitable area, and distribution is fixed on rigid screen skeleton, strainer bone
Frame is fixed on pile foundation support table by mounting groove, constitutes rigid screen barrier.
Automatic fishing device is calculated as liftable structure, and accessory structure is optimized according to bamboo pole and rubbish etc., the speed of service
Dynamic adjustment is carried out according to floating material and salvaging amount.Network chain front end sets mechanical swing arm, by the smooth importing of rod-shaped floating material.
