Technical Field

[0001] The utility model relates to the technical field of alarms, in particular to a flood alarm device for a fire pump room. Background Art

[0002] The fire pump room flooding alarm device is a device used to monitor whether there is flooding inside the fire pump room. Once flooding is detected, an alarm signal will be issued in time so that appropriate emergency measures can be taken. By installing a fire pump room flooding alarm device, flooding in the fire pump room can be discovered and handled in a timely manner, effectively preventing damage to pump room equipment and safety accidents, and improving the reliability and safety of fire protection facilities.

[0003] According to a disclosed fire pump room flooding alarm device (publication number: CN 215987551 U), it includes a fixed frame, a buzzer and a float. A sliding groove is provided on the top wall of the fixed frame. A connecting plate is slidably connected inside the sliding groove. A fixing rod is fixedly installed in the middle of the top wall of the connecting plate. A limiting groove is provided on the top wall of the fixing rod. A connecting rod is arranged inside the limiting groove. The bottom end of the connecting rod passes through the inner bottom wall of the limiting groove and extends to the outside of the limiting groove. A limiting plate slidably connected to the inner side wall of the limiting groove is fixedly installed on the top wall of the connecting rod. A battery is arranged on the top wall of the limiting plate. The limiting plate is connected to the negative pole of the buzzer through a wire. In the above application, when the water waves cause the float of the fire pump room flooding alarm device to float upward, the battery fits more closely to the bottom wall of the buzzer, so the buzzer is still in working condition, avoiding the interruption of the sound of the buzzer. However, since the battery is connected to the float, it may be soaked in the flooding process, causing damage to the use of the buzzer, and the device needs to wait until the liquid level rises to a certain level before it can be activated, which is not sensitive enough.

The paddle 12 and the cathode paddle 13 are located on the anode circuit and cathode circuit of the buzzer 9. The mounting shell 8 is made of insulating material to avoid leakage problems. A slider 10 is slidably connected to the bottom side of the mounting shell 8, and a pressure plate 11 is fixedly installed on the side of the slider 10. The upper end of the shell 1 is a bucket-shaped structure, which can amplify the alarm sound generated by the buzzer 9. The lower end of the slider 10 is fixedly connected to one end of the wire rope 6, and the other end of the wire rope 6 is fixedly connected to the upper end of the L-shaped rod 5. The wire rope 6 passes through the fixing seat 7 and is movably connected to the fixing seat 7. The utility model is connected through two contactors 14, and the circuit of the buzzer 9 is connected, so that the buzzer 9 is turned on. The funnel-shaped structure on the upper side of the shell 1 is set to make the alarm sound of the buzzer 9 spread, which can play a better alarm role, will not cause the liquid level to flood the battery, will not affect the buzzer 9, and the ground will be quickly absorbed by the sponge board 4 after the flooding, and does not require a higher liquid level to trigger.

[0021] When in use, the device is buried as a whole underground in the pump room so that the bottom plate 2 is flush with the floor of the pump room. When the pump room is flooded, the water contacts the sponge board 4 and is gradually absorbed by the sponge board 4. The weight of the sponge board 4 gradually increases, and the sliding plate 3 moves vertically downward along the inner wall of the shell 1 under the action of gravity. When the sliding plate 3 moves downward, it drives the L-shaped rod 5 to rotate. When one end of the L-shaped rod 5 rotates, it drives the other end to rotate counterclockwise. The L-shaped rod 5 drives the slider 10 to move vertically downward in the installation shell 8 through the pressure plate 11. At this time, the spring on the upper side of the slider 10 is in a stretched state. After the slider 10 moves downward, the anode paddle 12 and the cathode paddle 13 lose their obstruction. The material is plastic, which has good elasticity, so that the upper ends of the anode paddle 12 and the cathode paddle 13 fit together. At this time, the two contactors 14 are connected, and the circuit of the buzzer 9 is connected, so that the buzzer 9 is turned on, and the funnel-shaped structure on the upper side of the shell 1 is set to make the alarm sound of the buzzer 9 spread, which can play a good alarm role. After the staff solves the water leakage problem, the staff can replace the sponge board 4 and manually lift the pressure plate 11 vertically upward, so that the pressure plate 11 is blocked between the anode paddle 12 and the cathode paddle 13, thereby disconnecting the two contactors 14 and stopping the alarm, avoiding the alarm sound waves from causing tinnitus and other problems to the staff. Embodiment 2

[0022] See also Figure 5 On the basis of the first embodiment, a plug rod 15 is slidably connected to the side of the sliding plate 3, and a groove is opened on the upper side of the sliding plate 3. A lower fixing piece 17 is fixedly installed inside the groove, and a sliding rod 18 is slidably connected to the lower fixing piece 17. An upper fixing piece 16 is fixedly installed on the lower side of the sponge board 4. The sliding rods 18 on both sides are displaced by pushing the plug rod 15, so that the upper fixing piece 16 and the lower fixing piece 17 can be fixed by the sliding rod 18. The upper fixing piece 16 and the lower fixing piece 17 are both provided with rectangular openings of the same specifications in the middle parts. The two sliding rods 18 are elastically connected by springs. In the absence of external force, the two sliding rods will not be inserted into the upper fixing piece 16 and the lower fixing piece 17. The utility model can control the sliding direction of the sliding rod 18 by pulling and pulling the plug rod 15. At this time, the sponge board 4 can be replaced, thereby ensuring a long service life of the device, which is beneficial to later use.

[0023] When in use, based on the first embodiment, when the sponge board 4 needs to be replaced, the insertion rod 15 is pulled out in the direction away from the sliding rod 18. After the sliding rods 18 on both sides lose the obstruction of the insertion rod 15, they are tightly pressed in the opposite directions under the elastic action of the spring. At this time, the sliding rod 18 no longer penetrates the upper fixing member 16 and the lower fixing member 17. At this time, the sponge board 4 can be replaced. After replacement, the position of the sponge board 4 corresponds to the groove on the upper side of the sliding plate 3, and the insertion rod 15 is pushed in the direction close to the sliding rod 18. The inclined block at the end of the insertion rod 15 drives the sliding rods 18 on both sides to move away from each other. At this time, the upper fixing member 16 can correspond to the lower fixing member 17, and the sliding rod 18 is inserted into the middle of the upper fixing member 16 and the lower fixing member 17.
