[0029] A flooded plant alarm system, refer to Figure 1-Figure 8As shown, it includes a water level signal acquisition device 100 and an alarm device, the water level signal acquisition device 100 and the alarm device are connected to the central control room 400, the water level signal acquisition device 100 is arranged on the side of the floating oil collection box 200, the water level signal acquisition device 100 is used to monitor the corridor water level 300, the alarm device includes a main plant alarm device 700, a unit layer alarm device 600 and a corridor alarm device 500, the water level signal acquisition device 100 has a slide rail assembly 10, a float assembly 20 and a communication assembly 30 The float assembly 20 is slidably connected to the slide rail assembly 10. The slide rail assembly 10 is provided with a sensor assembly 14. The sensor assembly 14 is used to sense the position of the float assembly 20. When the water level rises, the float assembly 20 moves upward under the action of buoyancy. The sensor assembly 14 thereby senses the position of the float assembly 20, and then reflects the corridor water level 300 in the corridor. The communication assembly 30 transmits the acquired water level signal to the central control room 400. The communication assembly 30 and the central control room 400 communicate wirelessly or wired.
[0030] Furthermore, the slide rail assembly 10 has a base 11, a guide rod 12 and a slide seat 13. The slide rail assembly 10 is connected to the side of the floating oil collection box 200 through the base 11. The slide seat 13 is slidably connected to the guide rod 12. The float assembly 20 is connected to the slide seat 13. The floating oil collection box 200 is located in the corridor below the unit layer, which is the lowest point in the factory. The floating oil collection box 200 mainly collects lubricating oil leaked from the unit. The water level signal acquisition device 100 is arranged on the side of the floating oil collection box 200 to obtain the water inlet information in the factory at the first time.
[0031] Furthermore, the guide rod 12 has two guide rods, and the slide seat 13 has a guide rod hole 131 , and the guide rod hole 131 is sleeved on the guide rod.
[0032] Furthermore, the base 11 includes connection blocks 111 disposed at both ends and a connection rod 112 disposed between the connection blocks 111 , and the sensor assembly 14 is disposed on the connection rod 112 .
[0033] Furthermore, the sensor assembly 14 includes an upper sensor 141 , a middle sensor 142 , and a lower sensor 143 , which are spaced apart from top to bottom on the connecting rod 112 .
[0034] Furthermore, the upper sensor 141, the middle sensor 142 and the lower sensor 143 are all proximity sensors, wherein the proximity sensor has a probe A and a sensed part B, the slide seat 13 is provided with a sensor hole 132 for installing the probe A of the proximity sensor, and the upper sensor 141, the middle sensor 142 and the lower sensor 143 on the connecting rod 112 are the sensed part B.
[0035] Furthermore, the distance between the upper sensor 141 and the middle sensor 142 is greater than the distance between the middle sensor 142 and the lower sensor 143. The purpose of such a setting is that if the signals of the lower sensor 143 and the middle sensor 142 are continuously sensed, indicating that the water level is shallow, only the sound and light alarm device can be activated. When the signals of the middle sensor 142 and the upper sensor 141 are continuously sensed, it indicates that the water is deep and the pumping device 800 needs to be activated.
[0036] Furthermore, the main plant alarm device 700, the unit level alarm device 600 and the corridor alarm device 500 are all sound and light alarm devices.
[0037] Furthermore, the float assembly 20 includes a connecting arm 21 and a float 22, one end of the connecting arm 21 is connected to the slide 13, and the other end is connected to the float 22. When there is water level in the corridor, the float 22 moves upward under the action of buoyancy, driving the slide 12 to move upward, and the sensor sensing head on the slide 13 and the sensor probe on the connecting rod 112 approach each other, thereby obtaining a sensing signal, indicating that the water level has reached the corresponding value. At this time, after the central control room 400 obtains the water level signal, the main plant alarm device 700, the unit layer alarm device 600 and the corridor alarm device 500 all send out sound and light alarms. When the slide 12 moves upward to the middle sensor 142, the pumping device 800 is started to start draining water outward.
[0038] Furthermore, the float 22 of the float assembly 20 is in contact with the ground when not floating, ensuring that as long as water enters the corridor, it can be sensed by the water level signal acquisition device 100.
[0039] Furthermore, the system further comprises a pumping device 800, which is installed at the bottom of the floating oil collection box 200. When water is detected, the alarm device is activated and the pumping device 800 is started.
