Technical Field

[0001] The utility model relates to the field of gates, in particular to a pneumatic shield-shaped gate. Background Art

[0002] Gates are control facilities used to close and open drainage channels and are an important part of hydraulic structures. The main functions of gates include intercepting water flow, controlling water levels, regulating flow, discharging silt and floating objects, etc. The design and use of gates are crucial to the normal operation of water conservancy projects. They can effectively manage and control the flow of water resources and meet various needs such as irrigation, power generation, and flood control.

[0003] A shield gate refers to a shield-shaped gate. Shield gates are mainly used on rivers. Shield gates can be assembled to facilitate installation at corresponding positions on the river. After being assembled, they can be used to intercept water flows on rivers of different widths, making it easier to use the shield gates.

[0004] However, when the existing shield gate is used, manual assistance is required for the flipping and adjustment of the shield gate, which consumes a lot of manpower and material resources, and is inconvenient to flip and adjust an independent shield gate among multiple shield gates, which is not conducive to the use of the shield gate.

[0005] Therefore, we proposed a pneumatic shield gate. Utility Model Content

The elastic angle plate 11 is in a matched and fitted state with the corresponding positions on the shield gate body 1 and the fixed plate 5. The elastic angle plate 11 helps to connect and seal the first connecting plate 9 and the second connecting plate 10. A matching retaining hole 13 is opened on the inner annular surface of the airbag 12 corresponding to the inflation tube 14. The retaining hole 13 runs through the inner surface and the outer surface of the corresponding position on the airbag 12. The retaining hole 13 helps to connect the inside of the airbag 12 with the inside of the inflation tube 14.

[0036] The working principle of the utility model is: during use, the lower surfaces of the fixing plate 5 and the mounting plate 6 are aligned with the positions where they need to be installed in the external river channel, so that the lower surfaces of the fixing plate 5 and the mounting plate 6 are matched and fitted with the corresponding positions in the external river channel, and the mounting plate 6 is further installed between the positions where they need to be installed in the external river channel through bolts 7. The bolts 7 can fix and limit the mounting plate 6, which is convenient for the stable use of the mounting plate 6. The mounting plate 6 can fix and limit the fixing plate 5 and the various components assembled on the fixing plate 5, which is helpful for the stable use of the fixing plate 5 and the various components assembled on the fixing plate 5.

[0037] A plurality of different fixing plates 5 and mounting plates 6 are installed at intervals along the river channel, and different shield gate bodies 1 are sealed to adapt to rivers of different widths. When the shield gate body 1 is used, the shield gate body 1 can intercept the river water in the river channel. When the height of the shield gate body 1 to intercept the river water needs to be adjusted, the shield gate body 1 needs to be flipped over.

[0038] When it is necessary to raise the height at which the shield-shaped gate body 1 intercepts river water, the air pump installed with the inflation tube 14 is turned on. When the external air pump is turned on, the air pump can inflate the air bag 12 through the inflation tube 14 and the retention hole 13 on the air bag 12. After the air bag 12 is inflated, the air bag 12 can push the fixed block 8 upward through the second connecting plate 10 that is fixedly connected. The fixed block 8 can push the shield-shaped gate body 1 upward, so that the shield-shaped gate body 1 drives the first connecting block 2 to rotate along the second connecting block 3 through the rotating shaft 4, so as to facilitate the shield-shaped gate body 1 to flip upward, which helps the shield-shaped gate body 1 to raise the height of intercepting river water in the river channel. When the second connecting plate 10 flips, it will drive the elastic angle plate 11 to flip along the first connecting plate 9. The elastic angle plate 11 facilitates sealing between the first connecting plate 9 and the second connecting plate 10, which helps to seal between the shield-shaped gate body 1 and the fixed plate 5.

[0039] When it is necessary to lower the height at which the shield-shaped gate body 1 intercepts river water, exhaust is performed through the air pump installed with the inflation tube 14, so that the gas in the airbag 12 is discharged through the retention hole 13 on the airbag 12, the inflation tube 14 and the air pump installed with the outside, so that the airbag 12 becomes smaller. When the airbag 12 becomes smaller, it can drive the second connecting plate 10 fixedly connected to it to flip downward. When the second connecting plate 10 flips downward, it can drive the shield-shaped gate body 1 to flip downward through the fixed block 8, so as to facilitate lowering the height at which the shield-shaped gate body 1 intercepts river water, which is helpful for the use of the shield-shaped gate body 1.

[0040] During use, when the shield-shaped gate body 1 is flipped and adjusted, manual assistance from staff is not required, which helps to save the manpower and material resources required for flipping and adjusting the shield-shaped gate body 1, and can conveniently flip and adjust an independent shield-shaped gate body 1 among multiple shield-shaped gate bodies 1, which is helpful for the use of the shield-shaped gate body 1.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
