[0030] The monitoring mechanism includes a wire 3. The wire 3 is arranged on the surface of the outer shell 1 and is used to connect the outer shell 1 and the infrared monitoring structure 31, thereby transmitting the monitoring conditions of the infrared monitoring structure 31 and the infrared emitter 32 to the buzzer 11, so that the buzzer 11 emits an alarm sound when the wastewater level exceeds the warning line, thus warning the on-site personnel. One end of the wire 3 far away from the outer shell 1 is fixedly connected with an infrared monitoring structure 31. The infrared monitoring structure 31 is used to monitor the wastewater level and transmit the monitoring conditions to the buzzer 11 through the wire 3. An infrared emitter 32 is fixedly connected to the lower surface of the infrared monitoring structure 31, and the infrared emitter 32 is used to emit infrared rays to monitor the wastewater level. An installation ear 33 is fixedly connected to the surface of the infrared monitoring structure 31, and an installation bolt 34 is movably connected to the surface of the installation ear 33.

The wire 3, the infrared monitoring structure 31 and the infrared emitter 32 are all existing products and are not the technical protection points of this application, so no more description will be made here.

[0031] Further, the protective cover 2 is used to protect the housing 1, protecting the screen 12 from being damaged by collision. There are four sets of connecting blocks 21. Two sets of connecting blocks 21 are distributed on the upper surface of the housing 1, and two sets of connecting blocks 21 are distributed on the upper surface of the protective cover 2. The connecting blocks 21 are used to connect the housing 1 and the protective cover 2. The rotating shafts 22 are in the shape of round rods, and there are two sets of rotating shafts 22. The rotating shafts 22 are used to realize the rotational connection between the housing 1 and the protective cover 2.

[0032] Further, both ends of the torsion spring 23 are fixedly connected to a set of connecting blocks 21 respectively. The protective cover 2 is rotationally connected to the housing 1 through the connecting blocks 21 and the rotating shafts 22. There are two sets of torsion springs 23. The torsion springs 23 are used to automatically pop up when the protective cover 2 is opened, so that it is not necessary to manually hold the protective cover 2 when controlling the water level alarm.

[0033] Further, both the first connecting plate 24 and the second connecting plate 25 are in the shape of plates. Slots 26 are provided on the surfaces of the first connecting plate 24 and the second connecting plate 25. The first connecting plate 24 and the second connecting plate 25 are used to realize the firm closing of the protective cover 2. The slots 26 are used for the insertion pins 28 and the clamping blocks 29 to be inserted into the first connecting plate 24 and the second connecting plate 25. The clamping grooves 27 are used to clamp the clamping blocks 29, so that the insertion pins 28 and the clamping blocks 29 will not rotate easily after being inserted into the first connecting plate 24 and the second connecting plate 25, thereby realizing the firm closing of the protective cover 2.

[0034] Further, the insertion pin 28 penetrates through the first connecting plate 24 and the second connecting plate 25. The insertion pin 28 is used to be inserted into the first connecting plate 24 and the second connecting plate 25. There are two sets of clamping blocks 29 distributed on the surface of the insertion pin 28. The sizes and shapes of the clamping grooves 27 and the clamping blocks 29 are the same. The clamping blocks 29 are used to be clamped into the clamping grooves 27, so that the insertion pins 28 and the clamping blocks 29 will not rotate easily after being inserted into the first connecting plate 24 and the second connecting plate 25, thereby realizing the firm closing of the protective cover 2.

[0035] Further, both ends of the wire 3 are fixedly connected to the housing 1 and the infrared monitoring structure 31 respectively. The wire 3 is used to connect the housing 1 and the infrared monitoring structure 31, thereby transmitting the monitoring conditions of the infrared monitoring structure 31 and the infrared emitter 32 to the buzzer 11, so that the buzzer 11 emits an alarm sound when the wastewater level exceeds the warning line, thereby warning the on-site personnel. The infrared monitoring structure 31 is used to monitor the wastewater level and transmit the monitoring conditions to the buzzer 11 through the wire 3. There are two sets of infrared emitters 32 distributed on the lower surface of the infrared monitoring structure 31. The infrared emitters 32 are used to emit infrared rays, thereby monitoring the wastewater level.

[0036] Further, both the mounting ears 33 and the mounting bolts 34 are distributed in four groups on the surface of the infrared monitoring structure 31. The mounting bolts 34 are movably connected to the infrared monitoring structure 31 through the mounting ears 33. The mounting ears 33 and the mounting bolts 34 are used to mount the infrared monitoring structure 31 and the infrared transmitter 32 on the pool wall of the wastewater tank. The wire 3, the infrared monitoring structure 31, and the infrared transmitter 32 are all existing products and are not the technical protection points of this application, so no more statements will be made here.

[0037] Working principle: When the protective cover 2 is opened, it will automatically pop up. When controlling the water level alarm, there is no need to manually hold the protective cover 2. After closing the protective cover 2, push the bolt 28 into the first connecting plate 24 and the second connecting plate 25, rotate the bolt 28 by 90 degrees and pull the bolt 28 backward so that the locking block 29 is snapped into the card slot 27, then the firm closing of the protective cover 2 can be achieved, thus realizing the protection of the outer shell 1 and protecting the screen 12 from being damaged by collision. Similarly, push the bolt 28 forward and rotate it by 90 degrees, then the bolt 28 can be pulled out to open the protective cover 2.

[0038] The infrared monitoring structure 31 is mounted on the pool wall of the wastewater tank through the mounting ears 33 and the mounting bolts 34. The infrared transmitter 32 emits infrared rays to monitor the water level line of the wastewater. When the water level line of the wastewater reaches a certain height, the infrared monitoring structure 31 will transmit the information to the buzzer 11 through the wire 3, and the buzzer 11 will emit an alarm sound to warn the on-site personnel, so that the on-site personnel can close the wastewater discharge in time.
