Description
Technical field
The invention belongs to hydraulic engineering field, the navigation structure and its operation method of specifically a kind of continuous operation.
Background technique
China's water system is very flourishing, and in occupation of the leading position of line haul, the water-borne commerce in China is also increasingly for water transport
Greatly, therefore for navigation structure there are increasingly higher demands.Currently, mainly there are ship lift and two kinds of ship lock in navigation structure,
Ship lift is mainly built in the biggish reservoir of drop, and ship lock is prevalent on various water transport routes.Ship lock investment it is smaller but
Conevying efficiency is low, and ship lift is high-efficient but technical requirements are high and are not suitable for the small place of head.Although both technologies all exist
It constantly innovates and improves, speed of opening the navigation or air flight and carrying capacity are all greatly improved, but always without solving a problem, that is,
It can not continuous operation.This problem has seriously affected the efficiency of navigation, and since ship size shape does not standardize, gives
Navigation brings certain trouble.Although present ship lift and ship lock pass through various innovations, the dam time excessively is greatly shortened, by
In cannot continuously pass through, often the waiting time, which results in congestion waterborne and a large amount of ships are stagnant for a long time much long in spending the dam time
Stay the case where, especially in Southwestern China area, many middle and small rivers often occur large-scale stagnant in the water transport busy period
Boat phenomenon, according to statistics, such case has brought tremendous economic losses.

The two sides of delivery roller group are equipped with openable and closable baffle, which can be adjusted with up and down adjustment according to different ship height,
It is connect above delivery roller group with marine transmission, driving device, both ends delivery roller component is equipped with below delivery roller group
It She Zhi not be assisted in navigation channel and downstream auxiliary navigation channel in upstream, the two sides of delivery roller group are limited by connecting plate to be fixed.
In actual use, marine transmission 7 is constantly in operating condition to the present invention, and upstream and downstream assists navigation channel logical
It crosses and monitoring data progress automatic telescopic adjusting is implemented to water levels of upstream and downstream to adapt to the drinking water depth before ship enters navigation structure
Degree.And guarantee that upstream auxiliary navigation channel Bottom Altitude is the upstream water level determined with 98% fraction, stretch mobility scale ± 5m；Under
Trip auxiliary navigation channel Bottom Altitude is the level of tail water determined with 98% fraction, and stretch mobility scale ± 5m.
As shown in Fig. 2, the navigation building of continuous operation completes the operation method that downstream ship reaches upstream from downstream, such as
Under:
Step 1: downstream ship reaches downstream first and assists navigation channel 41 by lower approach 2, and ship head enters downstream the
After one auxiliary navigation channel 41, stopping working, the transverse-electromagnetic iron 71 of ship two sides is powered by sensor adjustment width, magnetic field is generated,
The balance of ship is constrained, while fixed metal plate transmission device 8 rises one piece of fixed metal plate 72 and consolidated in front of ship
It is scheduled in marine transmission 7；
Step 2: ship and fixed metal plate 72 are under the drive in marine transmission 7, completely into the first support vessel of downstream
Road 41 assists the sensor in navigation channel 41 to obtain boat length, the relevant parameters such as height, fixed metal plate transmission positioned at downstream first
Device 8 rises fixed metal plate 72 at ship rear again and is fixed on large ship transmission device 7, and the magnetization that is powered generates magnetic
, constrain the front-rear position of ship；In the process, the transverse-electromagnetic iron 71 above marine transmission 7 and two blocks of front and back gold
Belong to plate 72 and together constitute the structure of fixed ship, the magnetic field that four blocks of electromagnet generate, will not be to ship due to being overlapped mutually interference
Electronic instrument inside oceangoing ship, the generations such as personnel's health harm.At the same time, under next ship enters according to the method described above
The first auxiliary of trip navigation channel 41, realizes continuous navigation.
Step 3: opening the gate 611 of the first lock head of downstream, and ship enters under the drive of marine transmission 7 to be reached
The first lock head of downstream 61.Ship moves under the drive of marine transmission 7, reaches 51 position of the first lock head of upstream, and
