Problems solved by technology

When the pneumatic shield gate is discharging and overflowing, the upstream surface of the shield plate will also bear the pressure of the overflow water curtain on the upper end of the gate body and the thrust in the direction of water flow under the condition of bearing the upstream water pressure, while the pneumatic shield gate is due to its Due to the structural characteristics, the two ends of the top of the gate cannot be effectively supported radially, so the vibration caused by the overflow will be formed

Embodiment Construction

[0021] The present invention will be further described below in conjunction with accompanying drawing.

[0022] Such as figure 1 As shown, the present invention provides a protective buffer device for a pneumatic shield-shaped steel gate, which includes a safety restraint belt 5 , one end of which is connected to the back of the water retaining shield 1 , and the other end is fixed on the base plate 6 . The safety restraint belt 5 can constrain the water shield 1 so that it cannot form an angle above the liftable angle (for example, 75°) of the water shield 1, so as to play a position-limiting role. At the same time, when the water retaining shield 1 rises, the safety control belt 5 will be stretched, so that the tension of the safety control belt 5 becomes larger, thereby increasing the fixing force of the water retaining shield 1 to suppress the vibration generated by overflow.

[0023] Further, the skeleton material of the safety restraint belt is high-strength canvas and ...

Abstract

The invention relates to a protective buffer device of a pneumatic shield steel gate, and relates to the technical field of a gate device. The protective buffer device is used for solving the technical problem of vibration caused by overflow in the prior art, the protective buffer device of the pneumatic shield steel gate comprises a safety restraining belt, by arranging the safety restraining belt on the back portion of water retaining shield plate, the safety restraining belt can be stretched to increase the tension of the safety restraining belt when the water retaining shield plate rises,and fixation force of the water retaining shield plate is increased to restrain the vibration caused by the overflow.

Description

technical field [0001] The invention relates to the technical field of gate devices, in particular to a protective buffer device for a pneumatic shield-shaped steel gate. Background technique [0002] Pneumatic shield-shaped steel gate is a new type of dam developed by combining the advantages of traditional steel gate and rubber dam. The main feature is the combined structure, which is suitable for water conservancy projects with different spans, and does not require pier connection. Especially in the gate and dam projects with large span, low water head and compact layout, it has an absolute advantage. It can not only meet the functional requirements of conventional gates, but also coordinate with the surrounding environment and fully meet the ecological and landscape requirements of modern water conservancy projects. It can be used not only for river courses and reservoirs, but also for seawalls, artificial landscapes, water diversion irrigation, drought prevention and ...
