The traditional extra-large integral dock gate has large volume and heavy weight because the dock gate is required to block large water pressure and has large stress everywhere and enough rigidity and strength; the device can meet the stable floating or sinking control use requirement only by arranging a plurality of cabins such as a fixed ballast cabin, a ballast water cabin, a tide cabin, a watertight air cabin, an equipment cabin, a control cabin and the like, so that the structure is complex; when the hydraulic jack is opened and closed every time, a large number of commanders and staff are matched to carry out floating drainage or ballast sinking in-place operation, engineering ship belt cables, dragging, pushing assistance and maritime departments are also required to be matched, the working procedures are more, the matched staff and equipment are more, the use cost is relatively high, and the working efficiency is low.
Because the ballast tank, the ballast pump valve pipeline and the ballast control equipment are arranged in the traditional large dock gate, the maintenance cost is higher at ordinary times.
In addition, along with the wider and wider width of the dock gate, the manufacturing and matching precision requirement of the sealing surface is higher, the matching difficulty with cill is increased, the water seepage and leakage probability is rapidly increased along with the increase of the sealing length, and many large dock gates always leak water in a bit.
As dock is wider, dock gate has larger shape and weight, complex structure and supporting control facilities, and higher manufacturing, using and maintaining costs, the above disadvantages are more and more prominent, and these disadvantages can be avoided by adopting the combined dock gate which is lifted off in sections. However, because the dock gate is formed by combining multiple sections, gaps are inevitably reserved between each section, and the dock gate of multiple sections cannot be sealed by a traditional vertical sealing surface. The problem of sealing the combined dock gate under water cannot be overcome in the past, and the design of the multi-section large dock gate is not practically applied by other units.

Detailed Description
The invention is described in further detail below with reference to the embodiments of the drawings.
The invention is premised on designing the dock gate in a combinable multi-segment form, for example, three-segment form, see figure 1. The middle section is a movable dock gate block 5 which can be fixed or lifted off and can be used as a fixed dock wall and a sealing surface (the same as the function of the conventional apex vertical cill) which are fixed on one side surface of one end of the lifted-off dock gate 7 on two sides; the sealing structure of the hanging dock gate 7 at two sides is consistent with the sealing principle and structure of the traditional common dock gate, but the steel structure of the dock gate is simple in structure and small in dead weight, and a ballast and sinking and floating control system and the like are not fixed. The three sections of dock gates can be lifted off and installed by a large gantry crane above.
The type of the sealing surface of the suspended dock gate is shown in figure 2, and the sealing of the suspended dock gate at the two ends is the same as the sealing principle of the common dock gate. When the dock gate works, one end of the small dock gate with the two ends hung from each other is pressed on the vertical cill of the apex dock wall under the action of water pressure, one end of the small dock gate is pressed on one sealing surface adjacent to the middle movable dock gate block under the action of water pressure, and the lower part of the small dock gate is pressed on the side cill at the bottom of apex.
The form of the sealing surface of the movable dock block is shown in fig. 3, the middle movable dock block needs to be positioned underwater, the middle movable dock block is equivalent to the vertical cill at one side of apex after being positioned, the bottom side bearing and sealing device can enable the lower part of the movable dock block to be tightly attached to apex cill, the normal sealing and water stopping effects are achieved, and the movable dock block can bear the water pressure born by the movable dock block and the pressure transmitted by the end faces of the two-side hanging dock block.
The side surface of the bottom of the movable dock gate pier 5 is designed to be sealed in a circle of a vertical horizontal plane, but is incomplete, and the movable dock gate pier only extends to the multi-section dock gate sealing structure of the invention, and the two upper ends of the sealing element are watertight sealed with the multi-section dock gate sealing structure and the movable dock gate pier structure; after positioning and fixing, the vertical seal is tightly attached to cill at the lower part of apex, so that the watertight performance of the side face of the vehicle is ensured; meanwhile, after installation and positioning, one side of the vertical sealing element and the self structure and cill outer side seal are positioned on the same vertical plane, so that a continuous sealing pressure-bearing surface in the vertical direction is formed; the vertical sealing element is tightly pressed with the sealing surface on cill under the dead weight pressure of the movable dock block and water, and a good seal is formed between the horizontal planes; the middle movable dock gate block can be regarded as a fixed dock wall, and the sealing surface of the side wall is a pressure bearing surface and a sealing surface of one end of the dock gate with two ends lifted away.
The vertical seal 1 fastened to the intermediate movable docking block 5 is the most important one, see fig. 6 and 7. The horizontal cross sealing element has high strength, high bearing capacity, small compression amount, long service life and small friction force with the steel structure, and is suitable for being used as a plane sealing element. The structure is simple, the prefabrication can be realized, the on-site measurement, trimming and adaptation can be realized, and the good sealing is ensured; meanwhile, the surface of the sealing piece is provided with a water storage groove (labyrinth seal), so that the sealing can be better ensured, and the sealing piece is fixedly connected with a movable dock gate block; is connected with a sealing strip at the bottom of the self body; the movable dock gate block is pressed on the cill sealing pressure-bearing embedded part together with the sealing part on the movable dock gate block, forms a seal with cill, and is integrally used as the pressure bearing and sealing of the side-hung dock gate.
The device is positioned between the two sealing surfaces to form various seals, as shown in figure 5, so that the sealing problem between the multi-section dock gate is well solved. The vertical seal 1 is connected to its own bottom seal 1 by a corner. The sealing pressure bearing pad 2 is fixedly connected with the movable dock gate and is horizontally and crosswise sealed, and the sealing pressure bearing pad is used as a sealing element and a pressure bearing element. The movable dock gate block 5 is pressed on the cill sealing pressure bearing embedded part 3 together with the sealing pressure bearing pad 2 on the movable dock gate block, and forms a seal with cill. And (4) sealing and fixing the sealing end of the movable dock gate block, and pouring epoxy inside. The main sealing parts are used as not only the movable dock gate block bottom plate bearing block, but also the horizontal sealing surface of the self structure and the vertical sealing surface of the self structure and the hanging-off dock gate. Through the vertical sealing piece, each section of the three-section dock gate is used as an independent concave sealing, and the upper half part of the concave sealing of the movable dock gate is a directly utilized hanging-off dock gate sealing surface. The seal here interacts with the vertical seal, being the sealing surface, forming an integral large sealing surface. The device only needs to check when the ship is undocked, the whole structure is convenient to maintain, and the maintenance cost is lower than that of the floating box type dock gate and the horizontal dock gate.
In addition to the above embodiments, the present invention also includes other embodiments, and all technical solutions that are formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of the present invention.
