Description

Technical Field

[0001] The utility model relates to the technical field of overflow gates, and specifically discloses an overflow gate capable of regulating water level. Background Art

[0002] The gate is a movable structure used to close, open or partially open the water-passing orifices in hydraulic structures. Its main function is to control the water level and regulate the flow. Generally, urban water systems have inner rivers and outer rivers. The inner rivers are the landscape and drainage systems in the city. They pump water and store water in the dry season to maintain the landscape effect, and discharge floods and drain water in the rainy season to keep the drainage in the city smooth. The outer rivers connect to the outer water systems of the city. The water level is affected by nature and rivers, and the water level changes with the seasons.

[0003] In order to maintain the water quality of the inland river and keep the water flowing, the inland river is pumped with water at one end and then overflows into the outer river at the gate at the other end. When a heavy rainstorm occurs, the water level of the outer river rises to a level higher than the controlled water level of the inland river through a traditional overflow gate. The water level of the outer river will overflow the gate and cause backflow, resulting in a rise in the water level of the inland river and large-scale waterlogging in the urban area. Therefore, an overflow gate with adjustable water level is needed. Utility Model Content

[0004] In view of the above-mentioned defects or shortcomings in the prior art, an overflow gate with adjustable water level includes a stone wall, a gate groove is installed on the inner side of the stone wall, and a gate plate is installed inside the gate groove, the gate plate consists of an upper gate plate and a lower gate plate, and the gate plate is connected to the lower gate plate by the upper gate plate through a linkage interface, an electric gate opening and closing machine is installed above the top of the gate groove, and a screw rod is passed through the electric gate opening and closing machine.

[0005] Preferably, the upper gate plate moves up and down after the lead screw is driven by the electric door opening and closing machine.

[0006] Preferably, the lower gate plate moves up and down after the linkage interface is driven by the upper gate plate.

[0007] Preferably, the bottom of the screw rod is connected to the upper gate plate.

[0008] Preferably, rubber sealing plates are installed at the connection places between the upper gate plate and the lower gate plate and the gate groove on both sides.

[0009] Preferably, the length and width of the upper gate plate and the lower gate plate are consistent.

[0010] Beneficial effect: The utility model is an overflow gate with adjustable water level. The traditional gate plate is set as an upper gate plate and a lower gate plate, and the upper gate plate and the lower gate plate are connected through a linkage interface, so that according to the water level changes of inland rivers and external rivers and the different needs of inspection and maintenance, the upper and lower gate plates can be started to control the water level, adjust the water flow or achieve the purpose of draining the water body, thereby effectively avoiding backflow or large-area water accumulation, and the use is convenient.

[0018] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings.

[0019] The accompanying drawings in the embodiments of the present invention: different types of section lines in the drawings are not marked according to national standards, nor do they impose any requirements on the materials of the components. Instead, they are used to distinguish the cross-sectional views of the components in the drawings.

[0020] See also Figure 1-5 A water level adjustable overflow gate comprises a stone wall 5, a gate groove 4 is installed on the inner side of the stone wall 5, and a gate plate is installed inside the gate groove 4, the gate plate consists of an upper gate plate 6 and a lower gate plate 7, and the gate plate is connected to the lower gate plate 7 by the upper gate plate 6 through a linkage interface 8, an electric gate opening and closing machine 1 is installed above the top of the gate groove 4, and a screw rod 2 is passed through the electric gate opening and closing machine 1.

[0021] The upper gate plate 6 moves up and down after the electric gate opening and closing machine 1 drives the screw rod 2 to move.

[0022] The lower gate plate 7 moves up and down after the linkage interface 8 is driven by the upper gate plate 6 .

[0023] The bottom of the screw rod 2 is connected to the upper gate plate 6 .

[0024] Wherein, rubber sealing plates 3 are installed at the connection places between the upper gate plate 6 and the lower gate plate 7 and the gate groove 4 .

[0025] The length and width of the upper gate plate 6 and the lower gate plate 7 are consistent.

[0026] It should be noted that in order to ensure the normal water level of the inner river, it is necessary to set up a dam at the junction of the inner and outer rivers. The upper gate plate 6 and the lower gate plate 7 are installed in the dam. When working normally, the upper gate plate 6 and the lower gate plate 7 are usually overlapped. When the water level exceeds the normal value, the water exceeding the water level will overflow from the gate top and discharge the gate plate. When a heavy rainstorm occurs, the heavy rain causes the water level of the outer river to rise, and the water level of the outer river exceeds the water level of the inner river. At this time, the electric hoist 1 can drive the screw rod 2 to move upward, thereby raising the upper gate 6 to block the backflow of the outer river water. The inner river can adopt strong drainage facilities to lower the water level of the inner river, thereby avoiding urban waterlogging due to rising river water; when the inner river needs to be repaired and dredged, the water body needs to be emptied. At this time, the electric hoist 1 drives the screw rod 2 to move upward to lift the upper gate plate 6, and the upper gate plate 6 drives the lower gate plate 7 through the linkage interface 8, and a water outlet is formed below the lower gate plate 7, thereby achieving the purpose of emptying the water body.

[0027] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
