Problems solved by technology
[0005] In the safety protection of concrete dam flood discharge holes, traditional protective engineering measures mainly include reinforcement reinforcement and structure optimization, etc., which are mainly aimed at static loads and seismic loads, without considering the impact of the threat of explosion attacks
Moreover, for the dams that have been built, the reinforcement measures for the flood discharge holes are not very operable and difficult to implement

Embodiment Construction
[0028] see Figure 1 to Figure 4 , the present embodiment provides a concrete dam using a device for protecting the flood discharge hole of the concrete dam from being attacked by an explosion in the hole of an unmanned aerial vehicle. On the gate 11 upstream of the hole.
[0029] The protection device is mainly composed of an electromagnetic chuck device 2, a rope 3, an air compression tank 4, an inflation tube 5, an electric control valve 6, an air bag 7 and an air release hole 10 arranged in sequence from front to back. in,
[0030] The electromagnetic chuck device 2 is an ordinary electromagnetic chuck, which can be adsorbed on the steel gate 11 when energized.
[0031] The rope 3 is connected between the electromagnetic chuck device 2 and the airbag 7 to play the role of fixing the airbag 7, and the length of the rope 3 depends on the distance from the gate 11 to the orifice.
[0032] There is a large amount of compressed air in the air compression tank 4, which is con...

The invention discloses a concrete dam and a flood discharge hole explosion-proof device thereof. The concrete dam comprises a dam body and a flood discharge hole of the dam body, wherein a gate and adownstream opening are formed in the upstream portion of the flood discharge hole, and the concrete dam is characterized in that the explosion-proof device is installed in the flood discharge hole and comprises an air bag located in the downstream opening of the flood discharge hole, an air bag is connected to the gate and / or the hole wall of the flood discharge hole, and the air bag has an inflation state of blocking the downstream opening of the flood discharge hole when being filled with gas and a vacant state of avoiding the downstream opening of the inclined hole when not being filled with gas. According to the flood discharge hole explosion-proof device, the protection device does not need to be refitted or the concrete dam does not need to be damaged, only the air bag needs to be inflated to block the opening of the flood discharge hole when the threat of the drone is detected, and in addition, the protection device has the advantages of being low in structural complexity, easyto manufacture, capable of facilitating rapid deployment, capable of saving time and labor, flexible and convenient to use.
Description
technical field [0001] The invention relates to the field of anti-explosion protection of concrete dam flood discharge holes, in particular to a protective device for preventing concrete dam flood discharge holes from being attacked by explosions in the holes of unmanned aerial vehicles, and is suitable for the anti-explosion protection of main pivot concrete dams in the period of war conflict or terrorist threat. Explosion safety protection. Background technique [0002] Water conservancy projects are important infrastructure projects of the country and the lifeblood of the local and even the country, so they have extremely important economic benefits and political significance. Under the action of extreme loads, once an accident occurs in the dam, it will cause a heavy blow to the property safety and life safety of the downstream people. [0003] Due to the limitation of the storage capacity of the reservoir, in order to discharge the flood that cannot be accommodated by ...
