Description

Technical Field

[0001] The invention relates to the technical field of mechanical equipment, in particular to a dock door structure which is convenient for cleaning silt. Background Art

[0002] With the development of the shipbuilding industry, the size of shipyard docks is getting larger and larger. Conventional dock gates use a closed box structure to separate the river water from the dock space.

[0003] The silt in the river will accumulate in the flat area downstream, and the silt will slowly accumulate on the outside of the dock gate. As the number of uses increases, the ballast tanks of ordinary dock gates will also become turbid and contain a lot of mud. As the river water and seawater are pumped into the ballast tanks by the ballast pumps, more and more silt will accumulate in the ballast tanks and cannot be discharged. Ordinary dock gates need to frequently clean the silt outside the dock gate and the silt in the ballast tanks and tidal tanks inside the dock gate, which is a large workload, time-consuming and costly. Summary of the Invention

[0004] The object of the present invention is to provide a dock door structure that is convenient for cleaning silt, so as to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a dock gate structure that is convenient for cleaning silt, comprising a slanted bottom plate of the dock gate, the slanted bottom plate of the dock gate having a certain height from the bottom, a dock gate bottom truss connected to the bottom of the dock gate, and the dock gate bottom truss is connected and fixed to the dock gate bottom frame, the side surface of the dock gate bottom frame is welded and fixed to the lower end of the dock gate bottom side plate, and a dock gate backwater surface passage opening is provided on the backwater side of the dock gate bottom side plate, and the slanted bottom of the dock gate slanted bottom plate without a ballast tank is connected to the river water, and the silt is discharged with the water flow.

[0006] Furthermore, the inclined bottom plate of the dock gate serves as a closed structure to constitute the upper foundation of the dock gate, and the inclined bottom plate of the dock gate adopts an inclined design.

[0007] Furthermore, the bottom truss of the dock gate is arranged below the inclined bottom plate of the dock gate in a hollowed-out form with multiple holes, and the bottom truss of the dock gate is rigidly connected to the bottom frame of the dock gate by welding.

[0008] Furthermore, the dock door bottom frame is welded together by H-shaped steel to form an integral dock bottom load-bearing structure, and the top surface of the dock door bottom frame supports the dock door bottom truss, and the side surface of the dock door bottom frame is welded to the lower end of the dock door bottom side plate.

[0009] Furthermore, the upper ends of the dock door bottom side plates are vertically welded to the edges of the dock door inclined bottom plates, and the dock door inclined bottom plates, the dock door bottom trusses and the dock door bottom frame together form a sediment deposition cavity that is closed on three sides.

[0010] Furthermore, the backwater channel opening of the dock gate is arranged on the backwater side of the bottom side plate of the dock gate, and the opening size of the backwater channel opening of the dock gate meets the entry and exit requirements of manual dredging equipment, and the backwater channel opening of the dock gate is directly connected to the cavity formed by the bottom frame of the dock gate.

[0011] Furthermore, an H-shaped steel top cross beam is installed on the top of the passage opening on the back water surface of the dock gate, and both sides of the passage opening on the back water surface of the dock gate are reinforced with vertical stiffening ribs.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The inclined bottom plate of the dock gate, the bottom truss of the dock gate, the bottom frame of the dock gate, the side plates of the dock gate and the back surface of the dock gate form a relatively closed space, and the sealing structure of the dock is connected to the river water on the water-facing side, and the outer side of the inclined bottom plate is connected to the river water, so it is not easy to accumulate silt. Even if there is silt, the amount of accumulation is very small. During the process of lifting it out of the water, the silt will be discharged out of the cabin with the water flow.

[0014] There is no bottom plate at the bottom of the dock gate, and the bottom is hollowed out, which prevents the part with the highest mud content in the river from being immersed in water, thereby reducing the mud content of the river water entering the dock gate and correspondingly reducing the amount of silt accumulation.

[0015] The dock gate bottom plate is located at a higher position and has an inclined structure, forming a watertight structure with the dock gate's dorsal surface, side surface and sealing surface. The dock gate's water-facing surface is connected to the river water, and the naturally immersed river water is used as ballast. The stabilizing moment generated by the dock gate's own weight and the ballast water naturally entering the dock gate is greater than the overturning moment generated by the water pressure outside the dock gate, stabilizing the dock gate. The structures above the inclined bottom plate of this dock gate are all tidal tanks, and there is no ballast required for ordinary pontoon-type dock gates, avoiding the workload of cleaning silt in the ballast tank.

[0016] This dock gate does not have the fixed ballast tanks and water ballast tanks required by ordinary box-type dock gates, and does not require corresponding ballast pumps and drainage pumps. Because there is no fixed ballast and no water ballast tanks, the corresponding equipment is less, the structure is simple, and the deadweight is less than half of that of ordinary dock gates, so the cost is correspondingly low; less equipment and fewer cabins make maintenance more convenient; without ballast tanks, there will be no silt accumulation in the ballast tanks; the tidal tanks are inclined and directly connected to the outside, and the small amount of silt that is usually accumulated will be naturally discharged with the water flow during the process of being lifted out of the water, avoiding the dredging work required for ordinary dock gates.

[0017] The H-shaped steel top beam, due to its large section modulus, can significantly improve the bending resistance of the top of the channel opening on the back surface of the dock gate. The vertical stiffening ribs are rigidly connected to the top beam through welding, thereby improving the overall structural bearing capacity. BRIEF DESCRIPTION OF THE DRAWINGS

The dock gate inclined bottom plate 1, the dock gate bottom truss 2, the dock gate bottom frame 3, the dock gate bottom side plate 4 and the like form a relatively closed space, the dock gate back water surface passage opening 5 is arranged on the back water side of the dock gate bottom side plate 4, and the opening size of the dock gate back water surface passage opening 5 meets the requirements of manual dredging equipment entering and exiting, and the dock gate back water surface passage opening 5 is directly connected to the cavity enclosed by the dock gate bottom frame 3, an H-shaped steel top crossbeam 6 is erected on the top of the dock gate back water surface passage opening 5, and the two sides of the dock gate back water surface passage opening 5 are reinforced with vertical stiffening ribs 7.

[0024] Working principle: The relatively closed space is formed by the inclined bottom plate 1 of the dock gate, the bottom truss 2 of the dock gate, the bottom frame 3 of the dock gate, the bottom side plate 4 of the dock gate, etc. This dock gate has no ballast tank, and there is no phenomenon of silt accumulation in the ballast tank. The bottom plate of the tidal tank is inclined and directly connected to the outside, which is difficult to accumulate. Even if it accumulates, it is easy to discharge the silt accumulated in the bottom space with the water flow. Compared with the conventional closed dock gate, the river water in the dock can be discharged through the drainage pump, but the accumulated silt is difficult to discharge. This type of dock gate structure is difficult to accumulate silt and has obvious advantages. The H-shaped steel top beam 6 can significantly improve the bending resistance of the top of the dock gate back water surface channel 5 due to its large section modulus. The vertical stiffening rib 7 is rigidly connected to the top beam 6 by welding to improve the bearing capacity of the overall structure.
