Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example (b):

referring to fig. 1 to 4, the utility model discloses a power station flood discharge alarm device, including alarm terminal 1 and casing 2, alarm terminal 1 is hand-carried by operating personnel. The shell 2 is detachably connected to the side wall of the hydropower station, a water inlet pipe 3 is communicated with the bottom of the shell 2, and the lower half part of the water inlet pipe 3 is inserted into water.

Be provided with a plurality of guide board 4 in the inlet tube 3, and a plurality of guide board 4 is the one side slope that keeps away from 3 inner walls of inlet tube and sets up downwards, and the unrestrained water that produces when making the surface of water receive the wind-force effect receives stopping of guide board 4, can not get into inlet tube 3 in a large number to can not touch alarm terminal 1 response. Two adjacent guide plates 4 are respectively arranged on two opposite sides of the inner wall of the water inlet pipe 3, so that water waves are more difficult to enter the shell 2, and the alarm accuracy of the alarm terminal 1 is further improved.

Be provided with filter screen 8 in the inlet tube 3, filter screen 8 is located 4 below of a plurality of guide board, prevents that the foreign particles from getting into inlet tube 3 and casing 2 to the life of this device has been improved. The outer peripheral surface of the water inlet pipe 3 is provided with a first water guide plate 9, and the first water guide plate 9 is arranged in a way that the middle part of the first water guide plate is inclined and points to the direction far away from the water inlet pipe 3. A second water guide plate 10 is arranged on one side of the shell 2, and the middle part of the second water guide plate 10 is arranged in a direction away from the shell 2 in an inclined mode. The first water guide plate 9 and the second water guide plate 10 are both located on one side where water flow impacts, when the water flow flows, the first water guide plate 9 and the second water guide plate 10 are impacted by the water flow, and the first water guide plate 9 and the second water guide plate 10 guide the water flow to two sides, so that impact force of the water flow on the device is reduced.

A plurality of adjustment tank 5 has been seted up to the roof in the casing 2, and the height inequality of roof in a plurality of adjustment tank 5. The top wall in the adjusting groove 5 is provided with an alarm switch 6, and the alarm switch 6 is in signal connection with the alarm terminal 1.

The alarm terminal 1 includes an alarm body 11 and a plurality of alarm lamps 12 disposed at one side of the alarm body 11, and the plurality of alarm lamps 12 are electrically connected to the corresponding alarm switches 6, respectively. The alarm body 11 is carried around by an operator. When the alarm switch 6 is activated, the alarm light 12 will illuminate, alerting the operator that the water level is about to reach the flood discharge level. The connection mode of the alarm terminal 1 and the alarm switch 6 is well known to those skilled in the art, and those skilled in the art can make reasonable configuration and design according to the actual situation.

A driving assembly 7 is arranged in the adjusting groove 5. The driving assembly 7 includes a fixing plate 71, and the fixing plate 71 is fixedly connected to the corresponding adjusting groove 5. The top of the fixing plate 71 is provided with a through hole 72, the upper half part in the through hole 72 is provided with a floating ball 73, and the floating ball 73 can float on the water surface. The bottom of the floating ball 73 is tied with a connecting rope 74, the bottom end of the connecting rope 74 penetrates through the corresponding through hole 72 to be fixedly connected with the inner bottom wall of the shell 2, and the length of the connecting rope 74 is long enough not to block the movement of the floating ball 73.
