[0002] Weather conditions in high-altitude areas can be unpredictable, and extreme weather phenomena such as snowstorms are common. Hydropower station flood discharge alarms are devices used to monitor water level changes and sound alarms when necessary. However, after a snowstorm, when a large amount of snow accumulates above the alarm, the sound will be blocked, making it difficult for the alarm to spread far away. As a result, residents and local communities around the flood discharge may not be warned in time, and therefore unable to take necessary precautions, making the damage caused by the flood even more serious.

[0025] Example

[0026] like Figure 1-6As shown, a flood discharge alarm mechanism for a high-altitude and cold hydropower station proposed by the utility model includes a support tube 2 and an alarm 4. The inner wall of the support tube 2 is provided with a plurality of fixed line clips for binding the connecting line 41. The fixed line clip is a device for fixing or fixing the line. This device is usually used in electrician or other handicraft work. The fixed line clip is usually used to fix the wire or other lines so as to carry out safe, neat and effective work. In addition, the fixed line clip can be in various forms, including clips, clamps, clamps, etc., and the specific form depends on its use scenario and the type of line to be fixed. The bottom end of the support tube 2 is fixedly connected with a mounting base plate 1, and the mounting base plate 1 is provided with a plurality of bolt holes distributed in a circumferential array and used for bolt insertion. The support tube 2 is provided with a plurality of sound-through holes 21 for sound to pass through. The outer wall of the support tube 2 is located directly above the sound-through holes 21 and is fixedly connected with a shield 22. The function of the shield 22 is to prevent wind and snow from directly falling into the support tube 2 through the sound-through holes 21. The bottom of the alarm 4 is provided with a connecting wire 41, which is used to provide power to the alarm 4. The bottom of the support cover 5 is provided with a threading hole 54 for the connecting wire 41 to pass through movably, and also includes: a shaking mechanism installed on the top of the support tube 2 to shake the snow down after being blown by wind; and a supporting mechanism arranged inside the support tube 2 to support the shaking mechanism to restore the original position after shaking.

[0027] Furthermore, the supporting mechanism includes a pair of supporting seats 23 fixedly connected to the inner wall of the supporting tube 2, each supporting seat 23 is fixedly connected to a supporting rod 24, and the opposite end of the supporting rod 24 is fixedly connected to a supporting ring 25, and the upper surface of the supporting ring 25 is provided with a plurality of balls 26 in a circular array, and the function of the balls 26 is to make the bottom of the supporting cover 5 shake more smoothly on the upper surface of the supporting ring 25.

[0028] Furthermore, the shaking mechanism includes a support cover 5 movably connected to the support ring 25, the top of the support cover 5 is fixedly sleeved with the bottom of the alarm 4, the outer wall of the support cover 5 is fixedly connected with a plurality of connecting rods 51, and the support cover 5 is connected to the conical shield 3 through the connecting rods 51. When snow falls on the conical shield 3, it will gradually slide downward under the influence of the inclined surface, and finally slide off the edge of the shield. This design effectively reduces the possibility of snow accumulation on the equipment. A plurality of suction blades 31 in a circular array are fixedly connected to the conical shield 3. When the wind blows the suction blades 31, the suction blades 31 are affected by the wind and generate momentum. At the same time, the suction blades 31 will also generate reaction force on the air. These action and reaction forces give the suction blades 31 kinetic energy, thereby driving the conical shield 3 to shake. The bottom of the support cover 5 is fixedly connected with a plurality of shaking rods 52, and the bottom end of the shaking rod 52 is fixedly connected with a balancing block 53 for restoring the support cover 5, the alarm 4 and the conical shield 3 to their original positions after shaking. The top of the balancing block 53 is at a certain distance from the lower surface of the support ring 25, but the balancing block 53 will get stuck in the support ring 25 when it moves upwards for a certain distance. Since the balancing block 53 has a low center of gravity, when the conical shield 3 is tilted by the wind, the torque generated by gravity is relatively small, and the conical shield 3 will only tilt against the top of the support tube 2, but will not fall down.

[0029] In this embodiment, when it is necessary to use the flood discharge alarm mechanism of a high altitude and cold hydropower station, such as Figure 1 As shown, the mounting base plate 1 is fixed at a designated position by means of the bolt holes provided on the mounting base plate 1. When a snowstorm comes, the snow will fall on the conical shield 3, and the wind will blow the suction blades 31 on the conical shield 3, so that the suction blades 31 drive the conical shield 3 to shake on the top of the support tube 2, and the bottom of the conical shield 3 after shaking will abut against the top of the support tube 2. At this time, the conical shield 3 will shake violently through the collision with the support tube 2, and the snow on the conical shield 3 will be shaken off. When the wind force decreases, the support cover 5 drives the alarm 4 and the conical shield 3 to return to the original position through the balance block 53 at the bottom of the shaking rod 52, and then the wind force repeatedly blows the suction blades 31 on the conical shield 3, so that the accumulation of snow on the conical shield 3 can be avoided. When the alarm 4 is activated, the sound will be transmitted to a distant place through the multiple sound holes 21 on the support tube 2 and the gap between the support tube 2 and the conical shield 3 for warning.

The preferred embodiments do not describe all the details in detail, nor do they limit the utility model to only specific implementation methods. Obviously, many modifications and changes can be made according to the content of this specification. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the utility model, so that technicians in the relevant technical field can well understand and use the utility model. The utility model is limited only by the claims and their full scope and equivalents.
