Description

Technical Field

[0001] This utility model belongs to the field of hydraulic gate technology improvement, and in particular relates to a floating box gate based on a free-center adjustable segmented flap gate. Background Technology

[0002] In recent years, due to factors such as global warming, rising sea levels, land subsidence, intensified storm surges, and frequent urban torrential rains, coupled with the increasing size of urban populations and economies, cities are facing a growing threat from storm surges, with increasingly severe consequences. To improve the storm surge and flood mitigation capabilities of large and medium-sized cities and safeguard regional social and economic development, the construction of floodgates at urban drainage outlets has become imperative.

[0003] Currently, commonly used sluice gate types mainly include hydraulic flap gates, planar double-opening arc gates, vertical lifting gates, and horizontal sliding gates. Hydraulic flap gates are suitable for estuaries with small spans and low water-blocking requirements, but they are difficult to maintain and repair. Planar double-opening arc gates are suitable for estuaries with larger spans and higher navigation requirements, but they require large gate housings, occupy a large area, and exert significant thrust on the hinges, often resulting in higher costs. Vertical lifting gates are technologically mature and suitable for estuaries with small spans, but they significantly impact navigation and require substantial vertical lifting force. Horizontal sliding gates are also suitable for estuaries with small spans, but require still water for opening and closing, and also require gate housings on both banks, occupying a slightly larger area. In summary, currently commonly used sluice gates are not suitable for urban drainage and preventing backflow. Utility Model Content

The flap gate assembly 102 is fixedly installed on one end of the gate leaf 101 by bolts. The water seal assembly 104 is fixed to one end of the gate leaf 101 by screws. The gate leaf 101 is bolted to the other end of the gate leaf 101. A flapping gasket 1011 is installed between the gate leaf 101 and the flapping assembly 102 to eliminate water leakage. The reverse slider assembly 103 is installed on the gate leaf 101 and placed at the corners of the side where the flapping assembly 102 is installed, so that the gate can be installed in the gate slot 30 more smoothly and the accuracy of the installation can be controlled more effectively.

A shaft hole is opened on the upper pivot seat 10231, and a... A shaft hole reinforcing plate is used to strengthen the strength and stability of the upper rotating shaft seat 10231. A corner support plate is provided on the outside of the upper rotating shaft seat. The corner support plate is also connected to the upper floating box body to reinforce the upper rotating shaft seat 10231. The upper floating box body has an internal hollow structure. Inlet and outlet valves are provided at its top and bottom respectively. The weight of the floating box is adjusted by the inlet and outlet of water through the valves. The bottom and top surfaces of the upper floating box body are both square structures, with the bottom surface area being larger than the top surface area.

[0038] The lower pontoon 1022 includes a lower pontoon body, a lower pontoon flap gate pivot plate 10221 is installed on the top of the lower pontoon body, a lower pivot tube is installed on the lower pontoon flap gate pivot plate 10221, and a bushing is installed inside the lower pivot tube. The bottom area of ​​the lower pontoon body is larger than the top area, and the top surface and bottom surface form an inclined surface structure.

[0039] The inlet and outlet valves include a screw plug and a combination washer. The combination washer is fitted onto the screw plug and then installed on the upper and lower float boxes via threads. To adjust the weight of the float box, simply open the screw plug, allowing the rising water to flow into the float box through the screw plug hole to adjust the float box counterweight.

[0040] The rotating shaft assembly includes a rotating shaft with a downwardly recessed rotating shaft opening on its circumferential surface. A first shaft end baffle is engaged in the rotating shaft opening. Two screw holes are opened at two points on the first shaft end baffle, and a first bolt is threaded into the screw holes. A first spring washer is fitted on the first bolt.

[0041] like Figure 7 As shown, the gate lifting shaft assembly 105 includes a lifting shaft 1051. A downwardly recessed opening is provided on the circumferential surface of the lifting shaft 1051. A second shaft end baffle 1052 is engaged in the opening. A threaded hole is provided at each end of the second shaft end baffle 1052. A second bolt 1053 is provided in the threaded hole. A second spring washer is fitted on the second bolt 1053. In use, the second bolt is fixed to the lifting lug seat, and the second shaft end baffle is used to fix the lifting shaft so that it is not easy to fall off.

[0042] like Figure 5 As shown, the water seal assembly 104 includes a water seal body 1041, on which multiple main sliders 1042 are provided, so that they can slide stably and smoothly into the door groove 30 during installation.

[0043] like Figure 4 As shown, the reverse slider assembly 103 includes multiple sliders with the same structure, including a sealing gasket 1031. A shear block 1032 is connected to each end of the sealing gasket 1031. A reverse slider 1033 is also installed on the sealing gasket 1031. The surface of the reverse slider 1033 is provided with a downwardly recessed circular groove. A bolt hole is provided at the bottom of the groove. The bolt hole is equipped with a bolt, and an elastic rubber gasket is fitted on the bolt.

[0044] like Figure 13 As shown, the floating box gate also includes a hydraulic hoist 20 for driving the gate up and down. The bottom end of the hydraulic hoist 20 is connected to the lifting lugs 1013 on both sides of the gate leaf 101 through the gate lifting shaft assembly 105. The lifting and lowering of the hydraulic hoist 20 makes the gate easier to maintain.

[0045] like Figure 14 , 15 As shown, the floating box gate also includes a gate slot 30, which is formed by pouring concrete and steel bars. The floating box gate and the hydraulic hoist 20 are installed on the gate slot 30. The gate is installed along the groove reserved on the gate slot. The upper part of the hydraulic hoist 20 is fixedly installed on the top of the gate slot. The hydraulic hoist 20 is used to lower the gate to the bottom of the gate slot and fix it at the bottom to realize its function as a water-blocking gate.

[0046] At the city drainage channel inlet, the gate slot 30 is cast using concrete and steel bars according to the design drawings. The pre-assembled gate and hydraulic hoist 20 are then installed on the gate slot 30. The hydraulic hoist 20 is used to lower the gate and place it in the installation position. After installation, the water inside and outside the city is separated. During normal drainage, the water inside the city is discharged by simply tilting the lower float box of the segmented flap gate upwards. At this time, the water level inside the city is higher than the water level outside the city. When the water level rises, the inlet and outlet valves on the float box are used to fill the float box, increasing its weight and pressing it against the frame, preventing water from flowing back into the city. When a large amount of water is discharged from the city, the lower float box alone cannot complete the drainage, so it will push the upper float box upwards, increasing the drainage outlet and increasing the drainage volume to discharge the water inside the city.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
