Description

Semi-suspension vertical sinking type ship lock gate

Technical Field

The utility model relates to a steamer shipping technical field, concretely relates to semi-floating formula ship lock gate that sinks perpendicularly.

Background

Ship lock, refers to a kind of "navigation building". In natural rivers, because of the regulation of flow, canalization navigation and the restriction of topographic conditions and water surface gradient on the canal, a step-shaped vertical section is required to form a concentrated water surface drop. The vessel must be moved directly through the drop by means of a special navigable building. Modern navigable buildings are most commonly used in ship locks. It is a box-shaped structure, consisting of upstream and downstream navigation channels and upstream and downstream gate head connecting chambers. The lock chamber is a chamber-shaped chamber for berthing a ship (or a fleet), and the water level in the lock chamber is adjusted by filling water or draining water in the lock chamber, so that the ship vertically ascends and descends between upstream and downstream water levels, and the water level difference of a concentrated channel is passed. The ship lock gate is a gate which is arranged on a ship lock head and used for retaining water, when a ship runs upstream from downstream, the indoor water level is reduced to be flush with the downstream water level, then the gate of the downstream lock head is opened, the ship enters a lock chamber, the lock gate is closed, water is filled, after the water level is raised to be flush with the upstream water level, the upstream lock head gate is opened, and the ship can exit the lock and run to the upstream through an upstream approach channel; when the ship runs from upstream to downstream, the brake-passing operation procedure is opposite to the brake-passing operation procedure. The existing ship lock gate mainly adopts a herringbone gate, and has the characteristics of quick opening and closing, reliable water tightness and large water pressure bearing, but because the opening mode of the herringbone gate is a double-leaf side-hung type, a water area on the upper side of the gate within the width range of the gate is used as a space for opening the gate, a ship cannot be close to and stay in the space, and when the water level of a lock chamber is too high, the space is filled with water, so that the water consumption is relatively long, meanwhile, the opening and closing of the herringbone gate are realized by complex mechanisms such as complex stretching, rotation and the like, the investment cost is high, and the herringbone gate is not suitable for being popularized and used in small and medium-sized power station.

SUMMERY OF THE UTILITY MODEL

In order to achieve the above object, the utility model adopts the following technical scheme:

the utility model provides a semi-suspension formula ship lock gate that sinks perpendicularly, is trapezoidal shape's gate main part including the cross-section, set up in the gate guide rail of gate main part both sides sets up on the ship lock head and with gate guide rail matched with gate guide slot is fixed in on the gate guide rail and be used for going up and down the gate lug of gate main part sets up on the ship lock head and with the gate hoisting device that the gate lug links to each other to and set up in ship lock chamber bottom and be located the gate holding tank under the gate main part.

Furthermore, the gate main body is of a steel concrete structure, the outer wall of the gate main body is formed by steel plates, and the interior of the gate main body is formed by pouring concrete.

Preferably, a connecting line of the two gate lifting lugs on the two sides of the gate main body is positioned right above the gravity center of the gate main body.

Preferably, the side of the gate body protruding is directed to a side of the lock chamber of the ship lock.

Compared with the prior art, the utility model discloses following beneficial effect has:

(1) the utility model discloses a set up the lock gate into the form of opening and close of vertical lift, when opening the lock gate, only need rely on the gravity of lock gate self, just can sink the lock gate into the gate holding tank, realize opening of lock gate, when closing the lock gate, also only need overcome the gravity of lock gate self, lift the lock gate, just can realize closing of lock gate, the hoisting device of opening and close of its lock gate only need can realize the promotion from top to bottom can, the structure of opening and close of lock gate has been simplified, the input cost of lock gate has been reduced; meanwhile, the ship lock gate is designed into a ladder-shaped structure, and the protruding part faces one side of the ship lock chamber, so that after the ship lock chamber is filled with water, the acting force of the water in the ship lock chamber on the ship lock gate is transmitted to the ship lock heads on two sides, and the bearing capacity of the ship lock gate is enhanced.

(2) The utility model discloses a gate main part is the steel concrete structure, and its outer wall comprises the steel sheet, and inside is pour by muddy earth and is formed, can not only guarantee the intensity of its structure, has also further reduced the manufacturing cost of ship lock gate simultaneously.

(3) The utility model discloses the line of two gate lugs of gate main part both sides is located directly over the focus of gate main part, when going up and down to it through the gate lug, the gate main part only receives the ascending effort of vertical direction, and can not form the effort between gate guide slot and the gate guide rail, has promoted the life of gate guide rail and gate guide slot, simultaneously, has also reduced the required promotion power of hoisting device when the ship lock gate goes up and down, has reduced the consumption of the energy.
