Abstract
The utility model discloses a water breaking structure for a steel gate and relates to an improved steel gate structure. The water breaking structure is simple, and a vacuum state formed between water flow and the gate is effectively avoided. The water breaking structure comprises a steel gate body which intercepts a water channel into an upstream position and a downstream position, and a plurality of water breakers which are arranged on the top of the body at intervals and are lugs protruding out of the top of the body. The water breakers are arranged on the top of the gate, so that when the water flow drops from the top of the gate, the radian of the water flow is less than that of the original water flow at the water breakers, the water flow with two radians is formed, a vacuum state between the water flow and the gate is avoided, the internal and external air pressure difference between the water flow and the gate is reduced, the pressure fluctuation is reduced, the same vibration frequency of the water flow is changed, and the noise generated by vibration is reduced. The water breaking structure is simple and is convenient to mount.

At present in the hydraulic engineering,, often the steel gate need be set in the river, through utilizing the steel gate, thereby reach abundant reasonable use water resource owing to receive the influence of natural environment and human use's water resource.In this process, when drop appears in water level, need be through the steel gate be tilted to discharge water, however when steel gate door pushed up water, occur easily: 1, be easy to generate vacuum state between current and the gate, form the strong vibration of inner and outer air pressure difference generation; 2, the easy and surrounding buildings deposits yields resonance of current directly influences gate and building on every side, and causes strong vibration noise, works the mischief to surrounding environment.
The utility model content
The utility model provides a kind of simple in structure to above problem, and the one's water breaks structure of the steel gate of the vacuum state of avoiding effectively forming between current and the gate.
The technical scheme of the utility model is: comprise the water channel interception is the steel gate body of upstream and downstream that also comprise some one's water breaks devices, said one's water breaks device is arranged on the top of said body at interval; Said one's water breaks device is the projection that protrudes in said bodies top.
Said one's water breaks device in the form of sheets.
The horizontal section of said sheet one's water breaks device is trapezoidal, and said trapezoidal top margin is towards the said upper reaches.
The horizontal section of said sheet one's water breaks device is a rectangle.
The longitudinal axis of said rectangle sheet one's water breaks device is consistent with water (flow) direction.
The longitudinal axis and the water (flow) direction of said rectangle sheet one's water breaks device are 1-20 ° of angle.
Said one's water breaks device is finger-like.
The horizontal section of said finger-like one's water breaks device is square, circular, triangle or trapezoidal.
Said finger-like one's water breaks device is arranged on the side of said steel gate bodies top towards the upper reaches.
Said finger-like one's water breaks device interleaved is arranged on said steel gate bodies top towards the side at the upper reaches with towards the side in downstream.
The utility model is provided with the one's water breaks device on the gate top, when making current from whereabouts, door top, one's water breaks device place is being arranged; The current radian forms the current of two strands of radians less than original current radian, has avoided the vacuum state between current and the gate; The inner and outer air pressure that reduces between current and the gate is poor; Reduce pressure oscillation, and changed the same vibration frequency of current, subdued the noise that vibration produces.The utility model is simple in structure, easy for installation.

The specific embodiment
The utility model comprises with steel gate 1 body of water channel 3 interceptions for the upper reaches 30 and downstream 31 that shown in Fig. 1-2 also comprise some one's water breaks devices 2, said one's water breaks device 2 is arranged on the top of said body at interval; Said one's water breaks device 2 is for protruding in the projection of said bodies top.
First kind of embodiment of the utility model is shown in Fig. 3-6, and said one's water breaks device 2 is finger-like.
Said finger-like one's water breaks device is arranged on the side of said steel gate 1 bodies top towards the upper reaches.Like Fig. 3.
Said finger-like one's water breaks device interleaved is arranged on said steel gate 1 bodies top towards the side at the upper reaches with towards the side in downstream.Like Fig. 4.Can reach same effect with one's water breaks device 2 is arranged in a crossed manner.
The horizontal section that more than is finger-like one's water breaks device is foursquare situation.The horizontal section of finger-like one's water breaks device can also be circular, triangle or trapezoidal in addition.When trapezoidal, like Fig. 5, shown in 6.
