Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further explained by combining the specific drawings.
The float chamber type vertical hinged door moisture barrier of the present invention comprises a moisture barrier gate 100, a rotating vertical shaft 200 and a gate opening and closing device (not shown in the figure). One side of the moisture-proof shutter 100 is rotatably provided in the door garage 10 by rotating the vertical shaft 200, as shown in fig. 1. When the tidal current is needed to be blocked, the tidal current blocking gate 100 is driven by the gate opening and closing device to rotate around the rotating vertical shaft 200 to the central tidal current blocking position of the river channel for tidal current blocking, as shown in fig. 2. When the tide-blocking gate 100 is stopped at a ship on the bank at ordinary times, the tide-blocking gate leaves the door storehouse 10 when needing to block tide, and is rotated and closed along the water flow direction, namely, the rotation direction of the tide-blocking gate 100 from the door storehouse to the center of the river channel to the tide-blocking position is along the water flow direction, and the tide-blocking gate is filled with water and sinks to block water after reaching the gate closing position. The important point here is that the rotation direction of the moisture barrier gate 100 is along the water flow direction, at this time, the water flow impact can assist the rotation of the moisture barrier gate 100, otherwise, the dynamic water resistance in the rotation process of the moisture barrier gate 100 is very large, and a large opening and closing force is required, and a part of the opening and closing force can be reduced by the rotation along the water flow direction.
Referring to fig. 3 to 6, the tidal gate 100 includes an upper float door body 110, a lower float door body 120, a middle connection truss 130, a plurality of middle overflow gates 140, and a plurality of middle fixed water-retaining panels 150.
The upper float chamber door body 110 and the lower float chamber door body 120 are arranged in a vertically symmetrical interval. A plurality of upper buoyancy tank partition plates 111 are arranged in the upper buoyancy tank door body 110 at intervals along the length direction, the plurality of upper buoyancy tank partition plates 111 partition the interior of the upper buoyancy tank door body 110 into a plurality of upper buoyancy tank bins 112, and an upper buoyancy tank water injection and drainage system (not shown in the figure) for injecting water or draining water into or from each upper buoyancy tank bin 112 is arranged in the upper buoyancy tank door body 110. A plurality of lower buoyancy tank partition plates 121 are arranged in the lower buoyancy tank door body 120 at intervals along the length direction, the plurality of lower buoyancy tank partition plates 121 partition the interior of the lower buoyancy tank door body 120 into a plurality of lower buoyancy tank bins 122, and a lower buoyancy tank water injection and drainage system (not shown in the figure) for injecting water or draining water into or from each lower buoyancy tank bin 122 is arranged in the lower buoyancy tank door body 120. The upper floating box door body 110 and the lower floating box door body 120 are designed in separate bins, so that water flow is prevented from flowing in each separate bin, and the stability of the moisture-proof gate 100 is guaranteed. Meanwhile, the upper float box door body 110 and the lower float box door body 120 are supported by steel structures, so that the upper float box door body 110 and the lower float box door body 120 are prevented from being damaged under water pressure.
The upper buoyancy tank door body 110 and the lower buoyancy tank door body 120 can provide buoyancy in the process that the tide blocking gate 100 rotates from the door storehouse 10 to the river channel central tide blocking position, so that the tide blocking gate 100 floats on the water surface, the opening and closing force of the tide blocking gate 100 is reduced, and the upper buoyancy tank door body 110 and the lower buoyancy tank door body 120 are used for providing buoyancy at the moment. When the tide blocking gate 100 reaches a preset tide blocking position, water is injected into the upper floating gate door body 110 and the lower floating gate door body 120, the tide blocking gate 100 slowly sinks to the gate sill 20 at the moment, and the upper floating gate door body 110 and the lower floating gate door body 120 are used for supplying gravity through water injection.
In addition, a top fixed water retaining panel 160 is disposed on the top surface of the upper buoyant box door body 110 near the moisture blocking side of the upper buoyant box door body 110 for increasing the water retaining height of the moisture blocking gate 100. Meanwhile, a top rail 170 is arranged on the top surface of the upper floating box door body 110, close to the non-moisture-blocking side of the upper floating box door body 110, so that the operation safety of personnel is improved.
The middle connection truss 130 is disposed between the upper and lower float door bodies 110 and 120, and is used to connect the upper and lower float door bodies 110 and 120. The intermediate connection truss 130 is made of a steel structure as an intermediate support, and ensures the stability of the entire structure of the moisture barrier gate 100.
A plurality of intermediate overflow gates 140 are provided at intervals in the length direction in the intermediate connection girders 130, and serve to reduce the running water resistance during the rotation of the gates. Specifically, each intermediate overflow gate 140 includes an upper turnover door body 141 and a hoist 142. The upper turnover door body 141 is located in the middle connecting truss 130, the upper end of the upper turnover door body is hinged to the bottom surface of the upper buoyancy tank door body 110, and the turnover direction of the upper turnover door body 141 from top to bottom is the water flow direction, so that the upper turnover door body 141 is closed conveniently, and the opening and closing force is reduced. The hoisting hoist 142 is disposed on the upper floating gate body 110 and connected to the upper turnover gate body 141, and is used to drive the upper turnover gate body 141 to turn over along the hinge point.
In the two processes of rotating the tide blocking gate 100 from the door storehouse 10 to the closing position in the center of the river channel and slowly sinking water injection, the middle overflowing gate 140 is in an open overflowing state, and when the tide blocking gate 100 completely falls on the gate sill 20 and needs to block tide, the upper overturning door body 141 is closed along the water flow through the winch hoist 142.
Meanwhile, referring to fig. 6, the upper turnover door 141 is located at the non-tidal side of the middle connection truss 130, the tidal direction is at the left side, i.e., the high head (tidal side/gate outer side) is at the left side, the water level at the left side (non-tidal side/gate inner side) is high and the water level at the right side (non-tidal side/gate inner side) is low in the tidal state, and the middle overflow gate 140 between the upper and lower float door bodies 110, 120 is disposed at the side biased to the right side (low water level side, i.e., non-tidal side/gate inner side), and the high head at the left side is used as the weight at this time of tidal blocking, thereby increasing the overall stability of the tidal gate 100.
The middle fixed water retaining panels 150 are vertically arranged in the middle connection truss 130 at intervals along the length direction, and are used for retaining water in the areas of the middle connection truss 130 except the middle overflow gates 140. Further, each of the middle fixed water-retaining panels 150 is located on the non-tidal side of the middle connection truss 130, referring to fig. 4, the tidal direction is on the left side, the high head (tidal side) is on the left side, the water level on the left side (tidal side/outside of the gate) is high in the tidal state, and the water level on the right side (non-tidal side/inside of the gate) is low, the middle fixed water-retaining panel 150 between the upper and lower pontoon door bodies 110, 120 is disposed on the side biased to the right side (low water level, i.e., non-tidal side/inside of the gate), and the high head on the left side is used as the ballast weight when the tide is blocked, which can effectively increase the overall stability of the tidal gate 100.
The operation principle of the moisture-proof gate 100 of the invention is that the water in the upper and lower floating box door bodies 110 and 120 is adjusted to meet the floating and sinking opening and closing of the gate, the gate can float and move to open and close when not filled with water, and the gate can sink to block water after being filled with water.
The moisture barrier gate 100 rests in the door garage 10 when not moisture-protected, and the maximum buoyancy provided by the lower gate door 120 is greater than the total weight of the moisture barrier gate 100. When the intermediate overflow gate 140, the upper floating gate body 110 or the intermediate connecting truss 130 needs to be overhauled, the water bodies in the upper floating gate body 110 and the lower floating gate body 120 are completely drained, the floating state of the moisture-proof gate is shown in fig. 7, the parts above the lower floating gate body 120 of the moisture-proof gate 100 are exposed out of the water surface, the moisture-proof gate 100 can achieve dry operation overhaul conditions, and the above states are only used for overhaul.
When the tidal gate 100 is stopped in the door house 10 on a daily basis, if the protruding water surface part is too high, the stopping stability of the tidal gate 100 and the landscape of the river are not facilitated, and therefore, water can be injected into the upper buoyancy tank door body 110 and the lower buoyancy tank door body 120 of the tidal gate 100 under daily conditions, so that the tidal gate 100 falls on the sill 11 of the door house 10, as shown in fig. 8.
When the tide blocking is needed, a part of water in the upper and lower buoyancy tank door bodies 110 and 120 is discharged, but is not completely drained, so that the tide blocking gate 100 is in a floating state in which the upper buoyancy tank door body 110 is also partially submerged, the part exposed out of the water surface is less, and the part submerged below the water surface is more, which is beneficial to ensuring the stability of the tide blocking gate 100 in the rotating process, and the middle overflowing gate 140 is in an open overflowing state at the moment, as shown in fig. 9.
When the tide blocking gate 100 reaches a predetermined gate closing position, water is injected into the upper float gate body 110 and the lower float gate body 120, at this time, the tide blocking gate 100 slowly sinks onto the gate sill 20, a water head difference is formed in the up-down direction in the sinking process, water flow can form high-speed water flow from the middle overflow gate 140 which is opened in the tide blocking gate 100 and a gap between the bottom surface of the lower float gate body 120 of the tide blocking gate 100 and the gate sill 20 under the action of the water head, the high-speed water flow formed by the gap between the bottom surface of the lower float gate body 120 and the gate sill 20 can wash sludge on the gate sill 20, and at this time, the middle overflow gate 140 is in an open overflowing state, as shown in fig. 10.
After the moisture-proof gate 100 completely falls on the gate sill 20, the upper turnover door body 141 is closed by the hoisting hoist 142 along the water flow, and since the rotation direction of the upper turnover door body 141 is consistent with the water flow direction, the upper turnover door body 141 can automatically close the door to stop water by means of the self weight and the impact force of the water flow, and at this time, the upper turnover door is in a closed moisture-proof state, as shown in fig. 11.
When the tide is stopped, a part of water in the upper and lower buoyancy tank doors 110 and 120 is discharged, but the water is not completely drained, so that the tide blocking gate 100 is in a floating state that the upper buoyancy tank door 110 is partially submerged, the part exposed out of the water surface is less, the part submerged below the water surface is more, the stability of the tide blocking gate 100 in the rotating process is ensured, and the middle overflowing gate 140 is in an opened overflowing state. Then, the moisture-proof damper 100 is rotated into the door storage 10, and water is injected so that the moisture-proof damper 100 falls on the sill 11 of the door storage 10.
The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
