Through the cooperation of the camera 17 and the scale line on the measuring rod 2, the moving height of the measuring rod 2 can be monitored in real time. At the same time, under the cooperation of the laser range finder 16 and the limiting plate 5, the moving height of the measuring rod 2 is further monitored, so as to ensure the accuracy of the water level monitoring data.
[0027] A connecting rod 20 is fixed on the top of the rear surface of the shell 1. An installation plate 21 is fixed on the end of the connecting rod 20 away from the shell 1. A plurality of installation holes 22 are formed in the installation plate 21. Through the installation holes 22 and the installation plate 21, the shell 1 can be fixed and installed on the side wall of the water pump house, which is convenient for the use of the subsequent device.

[0030] At the same time, under the action of the laser range finder 16, the height of the limiting plate 5 is monitored, and the monitoring data is transmitted to the controller 18, and the initial water level in the water pump house is further monitored;
[0031] When the water level in the water pump house rises, the measuring rod 2 is driven to move upward under the action of the floating plate 3, the scale line on the measuring rod 2 is photographed by the camera 17, and the purpose of monitoring the water level change in the water pump house is achieved, and the height of the limiting plate 5 is monitored by the laser range finder 16, and the water level change in the water pump house is further monitored, and the accuracy of the water level monitoring data is effectively improved;
[0032] Among them, with the rise of the water level in the water pump house, the measuring rod 2 is continuously driven to move upward, when the water level in the water pump house rises to the need for staff to evacuate, the second copper sheet 7 is in contact with the first copper sheet 6 and the copper rod 12 at the same time, under the action of the wire, a closed circuit is formed between the battery pack 8, the first alarm 9, the first copper sheet 6, the second copper sheet 7, the copper rod 12 and the copper plate 11, so that the first alarm 9 is connected to the power supply, and the alarm is issued to realize the function of water level monitoring and alarm of the water pump house;
[0033] Among them, when the second copper sheet 7 contacts the copper rod 12, with the rise of the water level in the water pump house, under the joint action of the measuring rod 2 and the limiting plate 5, the second copper sheet 7 drives the copper rod 12 to be lifted upward along the inner cavity of the sleeve 10 until the fixed ring 14 contacts the pressure sensor 15, at this time, the pressure sensor 15 receives the pressure signal and transmits the signal to the controller 18, and the second alarm 19 is started by the controller 18 to issue an alarm, realizing the purpose of double alarm, solving the problem that most of the existing water level monitoring devices are water level sensors, which can only realize the function of monitoring the water level, and cannot realize the function of timely alarm when the water level is high, and the use effect is not good, and solving the problem that most of the existing water level monitoring devices are water level sensors, when the water level sensor fails, the water level monitoring function of the water pump house cannot be realized, and the alarm cannot be issued in time when the water level in the water pump house is abnormal, resulting in the problem of safety accident;
[0034] Wherein under the elasticity of spring 13, the lower end of copper rod 12 is tightly attached to the second copper sheet 7, which ensures the stability of the closed circuit formed between battery pack 8, first alarm 9, first copper sheet 6, second copper sheet 7, copper rod 12 and copper plate 11, and at the same time, copper plate 11 effectively prevents copper rod 12 from falling out of the inner cavity of sleeve 10, ensuring the use effect of copper rod 12.
