Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic gates, in particular to a distributed modular upturned gate water gate structure. Background Art

[0002] The up-flip gate is a commonly used gate type in water conservancy projects. The up-flip gate is generally composed of a water-retaining gate leaf structure and a horizontal bottom shaft. The water-retaining gate leaf structure rotates around a fixed horizontal bottom shaft. In the non-water-retaining state, the gate lies flat in the groove of the gate bottom sill, flush with the bottom surface of the riverbed; in the water-retaining state, the gate rotates upward around the horizontal pivot to achieve the water-retaining function. The gate is opened and closed by the bottom pivot, the air bag behind the gate, or the piston hydraulic hoist. Commonly used up-flip gates are bottom-shaft driven flap gates and floating gates. Compared with other gate types, the up-flip gate has the significant advantages of fast opening and closing speed, no impact on navigation, and small engineering footprint, but its disadvantages are also obvious. The gate is located underwater for a long time, difficult to repair, and the single-hole span is limited, and it is impossible to achieve super-large span water retention.

[0069] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific illustrations.

[0070] See also Figure 1 Combined with Figure 2 and Figure 3 The figure shows a distributed modular upturned gate water gate structure, including a plurality of upturned gate water gate units 100 arranged side by side in a direction perpendicular to the water retaining direction, each of which includes a water gate sill module 110 and a prefabricated integrated upturned gate module 120.

[0071] The top surface of the sluice sill module 110 is formed with an installation groove 111. The prefabricated integrated flip-up door module 120 is installed in the installation groove 111 of the sluice sill module 110. During normal operation and daily maintenance, the sluice sill module 110 and the prefabricated integrated flip-up door module 120 are combined together to form a complete flip-up door sluice structure. Under overhaul conditions, the sluice sill module 110 is fixed on the riverbed, and a single prefabricated integrated flip-up door module 120 can be lifted as a whole and overhauled on a floating dock or on shore. A single flip-up door sluice unit 100 is in a closed state, such as Figure 2 As shown, a single upward-flipping door sluice unit 100 is in an open water-blocking state, such as Figure 3 shown.

[0072] In order to facilitate further understanding of the working principle of the distributed modular upturned door sluice structure of the present invention, the sluice sill module 110 and the prefabricated integrated upturned door module 120 are introduced in detail below.

[0073] 1. Introduction to sluice sill module 110

[0074] See also Figures 4 to 9 The sill module 110 of the water gate adopts a prefabricated reinforced concrete sill module. The sill module 110 is closed on all sides, and a mounting groove 111 is opened on the middle top surface. The top of the mounting groove 111 is large and the bottom is small. The shape and size of the prefabricated integrated flip door module 120 are adapted to the mounting groove 111, so that the prefabricated integrated flip door module 120 can be easily sunk in the mounting groove 111.

[0075] A plurality of protrusion supports 112 for supporting the prefabricated integrated flip-up door module 120 are arranged at intervals on the bottom surface of the installation groove 111 of the sluice sill module 110. The bottom of the prefabricated integrated flip-up door module 120 is placed on the protrusion supports 112 during installation.

[0076] Since the water flow inside the installation groove 111 of the sluice sill module 110 needs to be discharged when the prefabricated integrated flip-up door module 120 is sunk, a plurality of front drainage channels 113a are arranged at intervals along the length direction in the front side of the sluice sill module 110, one end of each front drainage channel 113a extends to the top surface of the sluice sill module 110, and the other end thereof is communicated with the bottom side of the installation groove 111. Similarly, a plurality of rear drainage channels 113b are arranged at intervals along the length direction in the rear side of the sluice sill module 110, one end of each rear drainage channel 113b extends to the top surface of the sluice sill module 110, and the other end thereof is communicated with the bottom side of the installation groove 111.

[0077] The front and rear corridors 114a and 114b are formed in the sluice sill module 110 at the front and rear sides of the installation groove 111. The front corridors 114a of all the sluice sill modules 110 are connected to serve as the inspection corridor of the entire sluice structure. The rear corridors 114b of all the sluice sill modules 110 are connected to serve as a comprehensive pipe gallery for municipal pipelines and also as a fire passage. Two sill communication holes 115 for connecting the installation groove 111 with the front corridor 114a are arranged on the partition wall between the installation groove 111 and the front corridor 114a in the sluice sill module 110 at intervals, serving as the communication passage between the sluice sill module 110 and the prefabricated integrated flip-up door module 120. The sill communication hole 115 needs to be temporarily closed when the sluice sill module 110 is installed, and will be opened after the prefabricated integrated flip door module 120 is sunk and installed, as a communication channel between the two, that is, the staff can enter and exit the prefabricated integrated flip door module 120 installed in the installation groove 111 through the sill communication hole 115 to perform daily maintenance on the equipment (the prefabricated integrated flip door module 120 is provided with a hole of the same size at the corresponding position). The left and right connecting channels 116a and 116b for connecting the front and rear corridors 114a and 114b are formed on the left and right sides of the installation groove 111 in the sluice sill module 110, which can realize the connection between the front and rear corridors 114a and 114b.

[0078] A plurality of prestressed holes 117 are reserved at intervals on the left and right sides of the sluice sill module 110. When two adjacent sluice sill modules 110 are connected, a plurality of prestressed steel bars (not shown in the figure) are correspondingly inserted into the prestressed holes 117 of the two adjacent sluice sill modules 110, so that the two adjacent sluice sill modules 110 are firmly connected, and a water stop structure is set between the two adjacent sluice sill modules 110 for anti-seepage treatment. This process is similar to the currently mature joint process of immersed tube tunnels.

[0079] 2. Introduction of prefabricated integrated flip door module 120

[0080] See also Figures 10 to 21 The prefabricated integrated flip-up door module 120 includes an empty box base 121 , a rotating shaft 122 , a door leaf 123 and a hydraulic opening and closing mechanism 124 .

[0081] The empty box base 121 is installed in the installation groove 111 of the sluice sill module 110. The empty box base 121 adopts a reinforced concrete structure, and is provided with a plurality of crisscross partition walls 1211 inside. These partition walls serve as force supports and divide the interior of the empty box base 121 into a plurality of independent chambers with different functions. Each partition wall 1211 is provided with a connecting door so that adjacent chambers are connected to each other. Fig.21 The overall layout inside the empty box base 121 is as follows: the two ends are hydraulic opening and closing rooms, and the internal frame space in the middle can be used to set up hydraulic systems, control systems, drainage systems, fire protection systems, electrical systems, etc.

[0082] The front side of the empty box base 121 is provided with a base connecting hole 1212 which is connected to the sill connecting hole 115 of the sluice sill module 120. The hole needs to be temporarily closed when the prefabricated integrated flip door module 120 is installed, and will be opened again after all the prefabricated integrated flip door modules 120 are sunk and installed, serving as a connecting channel between the prefabricated integrated flip door module 120 and the sluice sill module 110.

[0083] The rotating shaft 122 is rotatably arranged on the empty box base 121. The door leaf 123 is fixedly arranged on the rotating shaft 122 and can be turned over by the rotating shaft 122. Specifically, left and right door leaf rotating seats 1213a and 1213b are arranged on the top surface of the empty box base 121, and the rotating shaft 122 is rotatably arranged in the left and right door leaf rotating seats 1213a and 1213b and penetrates the left and right door leaf rotating seats 1213a and 1213b. The left and right ends of the rotating shaft 122 extend out of the left and right door leaf rotating seats 1213a and 1213b by a certain length and the extended part is fixedly connected to the door leaf 123, and the part of the rotating shaft 122 located between the left and right door leaf rotating seats 1213a and 1213b is also fixedly connected to the door leaf 123. The total length of the rotating shaft 122 is equal to the length of the sluice sill module 120 at the corresponding position.

[0084] The door leaf 123 includes a door leaf panel 1231 and a plurality of door leaf main beams 1232. One side of the door leaf panel 1231 is fixedly connected to the rotating shaft 122. The plurality of door leaf main beams 1232 are arranged at intervals along the length direction on the board surface of the door leaf panel 1231 facing the empty box base 121. The door leaf panel 1231 is mainly used to block water and transmit the water pressure to the door leaf main beams 1232 arranged at intervals. A water stop rubber strip 1233 is arranged at the position where the front side edge of the door leaf panel 1231 contacts the sluice sill module 120. A plurality of secondary beams (not shown in the figure) are arranged at intervals along the length direction of the door leaf main beams 1232 between two adjacent door leaf main beams 1232 on the door leaf panel 1231. The secondary beams can be arranged according to the water blocking situation.

[0085] A plurality of door-hanging protrusions 1214 are arranged on the top surface of the empty box base 121 at positions corresponding to the plurality of door leaf main beams 1232. When the gate is in a closed state, the door leaf main beams 1232 are correspondingly placed on the door-hanging protrusions 1214, and the positions of the door-hanging protrusions 1214 and the door leaf main beams 1232 correspond to each other.

[0086] Since the prefabricated integrated flip-up door module 120 needs to be lifted out from underwater during overhaul, and due to the obstruction of the door leaf 123, a number of lifting ring protrusions 1215 are arranged at intervals along the length direction at the front side edge of the top surface of the empty box base 121. The height of the lifting ring protrusion 1215 is higher than the height of the door shelf protrusion 1214, so as to facilitate the fixation of the hook during underwater operation. The lifting ring protrusions 1215 are arranged to avoid the door leaf main beam 1232.

[0087] Each lifting ring protrusion 1215 is correspondingly located between two adjacent door leaf main beams 1232 and is provided with a front lifting ring 12151, and the lifting ring 12151 is hidden under the door leaf 123. A lifting ring through hole 12311 is provided at a position of the door leaf panel 1231 relative to each lifting ring protrusion 1215, and the aperture of the lifting ring through hole 12311 needs to meet the operating space required for the connection between the hook and the lifting ring during underwater operation. During lifting, the lifting rope can pass through the lifting ring through hole 12311. The lifting ring protrusion 1215 corresponds to the position of the lifting ring through hole 12311 reserved in the door leaf panel 1231. At the same time, a plurality of rear lifting rings 1216 are arranged at intervals along the length direction at the rear side edge of the top surface of the empty box base 121.

[0088] The hydraulic opening and closing mechanism 124 is arranged in the empty box base 121 and connected to the rotating shaft 122, which is used to drive the rotating shaft 122 to rotate, thereby driving the door leaf 123 to flip. Specifically, the hydraulic opening and closing mechanism 124 is connected to the part of the rotating shaft 122 located in the left and right door leaf rotating seats 1213a and 1213b, and drives the rotating shaft 122 to rotate. In this embodiment, there are two hydraulic opening and closing mechanisms 124, which are respectively arranged in the hydraulic opening and closing equipment room in the left and right sides of the empty box base 121, and include a crank arm 1241, a hydraulic rod support seat 1242 and a hydraulic rod 1243. The crank arm 1241 is fixedly mounted on the part of the rotating shaft 122 located in the left door leaf rotating seat 1213a or the right door leaf rotating seat 1213b. The hydraulic rod support seat 1242 is arranged on the bottom surface of the empty box base 121. The hydraulic rod 1243 is arranged in the empty box base 121, the middle part of the rod body is hinged on the hydraulic rod support seat 1242, and the driving end is hinged to the connecting end of the crank arm 1241.

[0089] See also Figures 15 to 17 When the gate is closed, it lies flat on the riverbed, and the gate leaf 123 rests on the gate resting protrusions 1214 arranged at intervals; when the gate is fully opened, the gate leaf 123 rests on the empty box base 121 to achieve locking. Fig.19 and Fig. 20 As the hydraulic rod 1243 pulls the crank arm 1241, the crank arm 1241 will drive the rotating shaft 122 to rotate, thereby realizing the opening and closing of the door leaf 123.

[0090] 3. Connection of the sluice sill module 110 and the prefabricated integrated flip-up door module 120

[0091] During construction, first complete the installation of the sluice sill module 110 (at this time, the sill connecting hole 115 of the sluice sill module 110 needs to be temporarily closed), and then install the prefabricated integrated flip door module 120 (at this time, the base connecting hole 1212 of the prefabricated integrated flip door module 120 needs to be temporarily closed). After all the installations are completed, open the connecting holes of the two. At this time, a circle of steel plates needs to be arranged around the connecting holes, and the two sides are connected to the two structures with anchor bolts respectively, and water-stopping measures are set. On the one hand, the connection between the sluice sill module 110 and the prefabricated integrated flip door module 120 can be ensured, so that the two parts of the structure will not be separated, and on the other hand, it plays an anti-seepage role. When overhaul is required, remove the surrounding steel plates, temporarily block the connecting holes between the sluice sill module 110 and the prefabricated integrated flip door module 120, and then the prefabricated integrated flip door module can be hoisted away for overhaul. The three-dimensional model of the assembled sill module 110 and the prefabricated integrated flip door module 120 is shown in FIG. Figure 2 and Figure 3 , the floor plan is shown in Fig. 22 .

[0092] Depend on Fig.26 It can be seen that after the installation of the sluice sill module 110 and the prefabricated integrated flip-up door module 120 is completed, the lifting hook and the lifting ring can be connected during underwater operations through the lifting ring through hole 12311 reserved in the door leaf 123, so that the prefabricated integrated flip-up door module 120 can be lifted out when it needs to be overhauled.

[0093] Depend on Fig. 27 It can be seen that a water-stopping rubber strip 1233 is provided between the end of the door leaf 123 and the sluice sill module 110 to prevent mud and sand from entering between the door leaf 123 and the empty box base 121 .

[0094] 4. Multiple upward-flipping gate sluice units 100 are combined to achieve ultra-large span water retaining

[0095] When a super-large span water retaining is required, multiple upward-flipping door water gate units 100 are arranged side by side at the water retaining position. The specific implementation method is as follows:

[0096] 1. Assembling the prefabricated sluice sill modules 110. After the prefabrication of multiple sluice sill modules 110 is completed, the multiple sluice sill modules 110 are connected in series by using prestressed steel bars to form a whole. Fig.28 As shown, a water stop structure is set between the joints of the sluice sill module 110 to prevent water seepage, forming a large section of serial sills, and the large section of serial sills is dragged to a predetermined position on the river channel and sunk to complete the installation. Repeat the above steps to achieve the installation of multiple large sections of serial sills, and water stops are also required between the large sections of serial sills to prevent water seepage between the large sections of serial sills. The sinking and assembly of the sluice sill module 110 can draw on the experience of immersed tube tunnel construction, and has the advantages of mature technology and low risks during construction and operation.

[0097] 2. After all the sluice sill modules 110 are installed, a single prefabricated integrated flip-up door module 120 is hoisted and installed in the installation groove 111 of each sluice sill module 110 .

[0098] 3. After all prefabricated integrated flip door modules 120 are installed, super-large span water blocking can be achieved, such as Fig.29 and Fig.30 shown.

[0099] Since each prefabricated integrated upward flip door module 120 does not affect each other, when one prefabricated integrated upward flip door module 120 fails, it does not affect the use of other prefabricated integrated upward flip door modules 120. When one prefabricated integrated upward flip door module 120 needs to be overhauled, the prefabricated integrated upward flip door module 120 can be directly lifted out, and then a spare prefabricated integrated upward flip door module 120 can be installed.
