Description
Technical Field
[0001] The invention relates to the technical field of hydraulic gates, and in particular to a tracked empty box transversely movable tide-blocking gate structure. Background Art
[0002] The horizontal sliding gate sluice gate blocks and releases water through the horizontal movement of the gate. Since there is no need to set up vertical opening and closing equipment, it has good landscape effect and is a common water conservancy engineering gate type for inland rivers with smaller estuaries.

For rivers entering the sea with a wide estuary, the span of the sluice gate is large, and the gate needs to be opened and closed in moving water due to the influence of the tide. The traditional horizontal sliding gate is limited in the wider estuary tide gate.

[0038] Figure 2 It is a partial enlarged schematic diagram between the hollow box type gate body and the gate bottom plate of the present invention. DETAILED DESCRIPTION
[0039] 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 diagrams.
[0040] Referring to the attached drawings, a rail-mounted empty-box transverse tide-blocking gate structure is shown, comprising a gate base plate 100, an empty-box gate body 200, a gate opening and closing device (not shown in the drawings), a sub-gate 300 and a sub-gate lifting and driving device (not shown in the drawings).
[0041] The gate bottom plate 100 is sunk and fixed to the predetermined river bottom, and is used to support the hollow box gate body 200. In this embodiment, the gate bottom plate 100 is a reinforced concrete hollow box structure, a steel hollow box structure, or a hollow box structure composed of reinforced concrete and steel structure, which is constructed by an immersed tube tunnel method or an underwater foundation pit retaining method.
[0042] The empty box gate body 200 is slidably arranged on the gate bottom plate 100. The empty box gate body 200 is a structure that is narrow at the top and wide at the bottom. It is divided into four layers from bottom to top in the vertical direction, wherein the longitudinal section of the first layer 210 is a long rectangle extending in the horizontal direction, the longitudinal section of the second layer 220 is a trapezoid, the longitudinal section of the third layer 230 is a long rectangle extending in the vertical direction, and the fourth layer 240 is a sub-gate pier 240 respectively constructed on both sides of the top surface of the third layer 230. The first layer 210 and the second layer 220 of the empty box gate body 200 are spaced downward along the downstream direction to form a multi-compartment empty box, and the third layer 230 of the empty box gate body 200 is a single compartment and a sub-gate installation groove 231 is provided in the middle of the downstream direction. The empty box gate body 200 is preferably made of steel structure, reinforced concrete structure or prestressed reinforced concrete structure.
[0043] In addition, the empty box gate body 200 can be spliced by at least one empty box gate unit, and the number of empty box gate units should be determined according to the total span of the tide gate. In order to ensure the water-blocking sealing performance between the empty box gate body 200 itself and the shore, a water-stopping sealing structure (not shown in the figure) is respectively provided on the tide-blocking side between two adjacent empty box gate units and between the empty box gate units on both sides and the shore wall.
[0044] The gate opening and closing device is installed in the empty box gate body 200, and is used to drive the empty box gate body 200 to slide back and forth laterally on the gate bottom plate 100. The gate opening and closing device is a device such as a motor or a diesel engine driving a hydraulic oil pump to provide power, which is a conventional device in the art and will not be described in detail here.
[0045] In order to make the empty box type gate body 200 slide back and forth laterally on the gate bottom plate 100, two front vertical rails 410 and a front horizontal rail 420 extending along the gate bottom plate 100 are respectively installed on the front side of the top surface of the gate bottom plate 100, and two rear vertical rails 430 and a rear horizontal rail 440 extending along the length direction of the gate bottom plate 100 are respectively installed on the rear side of the top surface of the gate bottom plate 100. A plurality of front vertical rollers 510 that slide with the two front vertical rails 410 and a plurality of front transverse rollers 520 that slide with the front transverse rails 420 are installed at intervals along the length direction on the side, and a plurality of rear vertical rollers 530 that slide with the two rear vertical rails 430 and a plurality of rear transverse rollers 540 that slide with the one rear transverse rail 440 are installed at intervals along the length direction on the rear side of the bottom surface of the hollow box type gate body 200. The hollow box type gate body 200 moves laterally on the gate bottom plate 100 through the cooperation of the rollers and rails, making it more flexible to open and close.
[0046] The sub-gate 300 is arranged in the sub-gate installation groove 231 of the hollow box gate body 200. The arrangement of the sub-gate 300 reduces the height of the main structure, saves materials, and coordinates with the surrounding environment. In this embodiment, the sub-gate 300 can be a flat gate structure or a hollow box steel gate structure, which can be raised and lowered along the sub-gate installation groove 231 of the third layer 230 of the hollow box gate body 200 and the sub-gate pier 240 of the fourth layer.
[0047] The sub-gate lifting drive device is installed in the empty box gate body 200, and is used to drive the sub-gate 300 to vertically lift. The sub-gate lifting drive device can be a hydraulic hoist or a sub-gate empty box filling and drainage device.
[0048] In addition, front and rear lower door buckle structures 610 and 620 are respectively arranged at the front and rear sides of the top surface of the gate bottom plate 100, which are continuously or spacedly distributed along the length direction of the gate bottom plate 100, and front and rear upper door buckle structures 630 and 640 are respectively arranged at the front and rear sides of the bottom surface of the empty box gate body 200, which are continuously or spacedly distributed along the length direction of the empty box gate body 200. When the empty box gate body 200 is placed on the gate bottom plate 100, the front and rear upper door buckle structures 630 and 640 are engaged with the front and rear lower door buckle structures 610 and 620 and can slide relative to each other in the direction perpendicular to the water flow, so that the empty box gate body 200 can be ensured to slide stably on the gate bottom plate 100, and the upper thrust of the empty box gate body 200 can also be transmitted to the gate bottom plate 100, which is safe and reliable and is not limited by the span of the water gate. In this embodiment, the front and rear lower door buckle structures 610, 620 are preferably "S" shaped door buckle structures, and the front and rear upper door buckle structures 630, 640 are reverse "S" shaped door buckle structures. The front and rear lower door buckle structures 610, 620 and the front and rear upper door buckle structures 630, 640 are made of corrosion-resistant and wear-resistant high-strength steel structures.
[0049] The rail-mounted empty box transverse tide-blocking gate structure of the present invention also includes a silt flushing device for flushing the front and rear vertical tracks 410, 430 and the front and rear transverse tracks 420, 440. Specifically, the silt flushing device includes a longitudinal main pipe 710, a plurality of transverse branch pipes 720 and a booster pump (not shown in the figure). The longitudinal main pipe 710 is buried in the gate bottom plate 100 and extends along the length direction of the gate bottom plate 100. One end of the longitudinal main pipe 710 is open and the other end is closed. A plurality of transverse branch pipes 720 are buried in the gate bottom plate 100 at intervals along the length direction of the gate bottom plate 100, and the distance between two adjacent transverse branch pipes 720 is 1m to 2m. The middle part of each transverse branch pipe 720 is overlapped on the longitudinal main pipe 710 and connected to the longitudinal main pipe 710. Each transverse branch pipe 720 is provided with a branch pipe nozzle 721 for spraying high-pressure water in communication with the transverse branch pipe 720 at a position close to the front and rear vertical tracks 410, 430 and the front and rear transverse tracks 420, 440. The booster pump is arranged in the management room on the shore side, and its high-pressure water outlet is connected to the open end of the longitudinal main pipe 710. The high-pressure water generated by the booster pump is transmitted to each branch pipe nozzle 721 through the longitudinal main pipe 710 and a plurality of transverse branch pipes 720, and is sprayed to the front and rear vertical tracks 410, 430 and the front and rear transverse tracks 420, 440 through the branch pipe nozzle 721, washing the siltation on the tracks, and ensuring the smooth opening and closing of the gate and the sealing and water blocking.
[0050] The working principle of the tracked empty box transverse tide-blocking gate structure of the present invention is as follows:
[0051] The empty box gate body 200 is usually located in the gate house on the bank side, and the sub-gate 300 is located in the sub-gate installation groove 231 of the third layer 230 of the empty box gate body 200, and the river channel is normally discharged and navigable. According to the tide level forecast, the siltation on the surface of the front and rear vertical tracks 410, 430 and the front and rear transverse tracks 420, 440 attached to the top surface of the gate bottom plate 100 is washed away by the silt flushing device before the high tide. The empty box gate body 200 is moved out of the gate house and placed at a predetermined position on the gate bottom plate 100. The sub-gate 300 is raised to block water along the sub-gate installation groove 231 of the third layer 230 of the empty box gate body 200 and the sub-gate pier 240 of the fourth layer.
[0052] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
