Abstract
The utility model relates to a high water head ship lock, which comprises a lock body, a head breadth chute on the lock body, a ship chamber upper gate at the water entrance of the head breadth chute, a ship chamber lower gate at the water exit of the head breadth chute, a ship chamber fender connected with the lock body above the ship chamber lower gate, a protecting groove connected with the water exit of the head breadth chute and a multi-level water-saving energy-paring groove. The ship chamber is injected with water. When ships enter the upstream river, water in the chamber should be discharged to let in ships in the downstream river. First, drain the water in the chamber into the water-saving energy-paring groove and store the water there. When downstream ships enter the chamber, water in the groove is injected into the chamber from the low to the high. The utility model has the following advantages. Firstly, chamber water supply from the upstream river is reduced, and navigable water consumption is saved by two thirds. Secondly, water is injected from the groove into the chamber from the low to the high, so the water level in the groove is almost the same with the water level in the chamber, and then water from the chamber causes little impact to ships in the chamber. The worldwide safety problem caused by collision between ships in the chamber and between ships and head breadth chute due to huge water table drop when injecting water directly from the upstream river is solved. So safety property is greatly improved. Thirdly, the single gate used in the utility model saves time for passing.
Description
(1) technical field
The utility model relates to the ship lock that a kind of ship is crossed river dyke, particularly a kind of high-lift lock.
(2) background technology
At present, the power station of building on the rivers, reservoir dam get more and more, to the current difficulty of having brought of ship.The ship lock that ship uses by dykes and dams, the ship in downstream entered cabin before this, closed the cabin tail gates, very long from the dykes and dams upstream to the cabin water filling, treat that the cabin water level rises to when concordant with the upstream, opens the cabin upper lock gate, up ship outbound ship chamber, descending ship sails cabin into, closes the cabin upper lock gate, very long water of emitting in the cabin, the cabin drawdown, when the cabin drawdown when concordant with the level of tail water, open the cabin tail gates, descending ship outbound ship chamber.In the process of cabin water filling, because the water level in upstream and the cabin differs greatly, the water filling current are also big to the impact of ship in the cabin, cause ship collision, safety can't guarantee, in the practice, the dykes and dams bigger to drop, the modes that adopt multilift lock more, but cause ship transit time lengthening, problems such as ship lock cost increase.Simultaneously, the every opening of ship lock once will bleed off quite and the water yield of cabin volume waste water resource in vain.
(3) utility model content
The purpose of this utility model is to overcome the problems referred to above of existing ship lock, and a kind of high water head safe ship lock of economizing on water is provided.
The technical scheme that realizes the utility model purpose is: but it comprise the lock body, the headchute on the lock body, the cabin upper lock gate of headchute water inlet position, the cabin tail gates of headchute delivery port position, with cabin baffle plate above the lock body is connected in the cabin tail gates mutually, be connected to the headchute delivery port go out ship protect groove, by the pipeline of switch and the multistage water saving energy saving groove of headchute connection.
Especially:
The water saving energy saving groove is positioned at the both sides of headchute.
Gate valve is installed on pipeline.
In the practice, look the environment position around the height of dykes and dams water levels of upstream and downstream drop and the ship lock, more water saving energy saving groove progression when the dykes and dams drop is big, is designed in the sum of series position of decision water saving energy saving groove, and drop hour designs less progression; During the riverbed broad, itself and lock body, headchute can designs in one, when the riverbed is narrower, can be with its design in lock body other place (will suitably determine its high and low position) in addition.
Because said structure of the present utility model, in the cabin fills with water, ship rolls ship lock away from and enters the river, upstream and need emit water in the lock chamber, when allowing the ship in downstream enter cabin, allow the pipeline of water by headchute and water saving energy saving groove of cabin enter the water saving energy saving groove earlier, water is accumulated in the water saving energy saving groove, after the ship for the treatment of the downstream enters cabin, by water saving energy saving groove order from low to high, successively the water in the groove is put into cabin.Thus, the one, reduced the water supply of upstream to cabin, the problem that when having overcome existing lock emptying the water-white in the cabin has been bled off in vain can be saved the navigation water more than 2/3rds; The 2nd, by water saving energy saving groove order from low to high, successively the water in the groove is put into the process of cabin, because the water level in the water saving energy saving groove and the water level of cabin are more or less the same, it is also little to the impact of ship in the cabin to discharge water, solved at present directly from the upstream to the cabin water filling, because the height of water of upstream and downstream is bigger, in the injecting process, between ship houseboat and the ship, between ship and headchute mutually collision cause the worldwide difficulty of security incident, safety improves greatly; Three are to use lift lock, save greatly and pass through the time.The power station, Three Gorges of China's maximum is a five-level ship lock, is generally 4-5 hour by the time, as adopting the technical solution of the utility model, can shorten to about 1 hour by the time.

Fig. 2 is an A-A sectional view among the utility model Fig. 1;
Fig. 3 is the utility model left view.
(5) specific embodiment
Be described further below in conjunction with accompanying drawing, but be not limited only to this.
As shown in Figure 1, 2, 3, the utility model includes lock body 1, at the headchute on the lock body 13, at the cabin upper lock gate 9 of headchute 3 water inlet position, at the cabin tail gates 5 of headchute 3 delivery port positions, with cabin baffle plate 2 above lock body 1 is connected in cabin tail gates 5 mutually, be connected to the secondary water saving energy saving groove (4) that ship protects groove 6, connected by pipeline (8) and headchute (3) that of headchute 3 delivery ports, pipeline (8) is provided with gate valve 7, water saving energy saving groove 4 is positioned at the both sides of headchute 3, is symmetrical arranged.
Using method of the present utility model is: when using first, allow the downstream ship protect groove 6 and enter cabin by going out ship, close cabin tail gates 5, cabin water filling from the ship lock upstream in headchute 3, after the cabin fills with water, open cabin upper lock gate 9, ship rolls ship lock away from and enters the upper river.Water in needs are emitted lock chamber, when allowing the ship in downstream enter cabin, open gate valve 7, allow earlier cabin water by pipeline 8 enter successively from high to low the water saving energy saving groove after closing gate valve 7, water is accumulated in the water saving energy saving groove, as after the whole fills with water of the energy saving groove of economizing on water, water level also is higher than the level of tail water in the cabin, then water is bled off by outlet sluice, open cabin tail gates 5 again, after the ship for the treatment of the downstream enters cabin, close cabin tail gates 5, cabin is put into the water in the groove successively by water saving energy saving groove order from low to high in the back.When the water level of superlative degree water saving energy saving groove with after the water level in the cabin is concordant, also not concordant as the water level in the cabin with upper pond level, then closing gate valve 7, open the upstream water filling port again to the cabin water filling, when the water level in the cabin is concordant with upper pond level, open cabin upper lock gate 9, ship rolls cabin away from, enters the upper river.
