Abstract

Sensor annunciator, consisting of a rail with leveling markings and an electronic metro rod fixed on it, containing a vertically placed indicator housing, in which light, sound and radio signaling devices are mounted, characterized in that the indicator electrodes are installed with the ability to protect them from mechanical damage, rain, ice and snow with the help of a metal umbrella, while the said electrodes are made with the possibility of automatic switching on of the electronic circuit and notification when the water reaches the control or critical level marks in the reservoirs.

Description

The sensor relates to control equipment, namely to devices for constant monitoring of the critical level of water in rivers and ponds, as well as an instant warning signal in emergency situations.

Closest to the proposed technical solution is a device for measuring the level and / or interface of liquid media (application of Russia No. 2001118599, IPC G01F 23/00), containing a sensor made of two conductive rods connected electrically with a functional amplifier. The sensor rods are interconnected in the lower part using a piezoelectric transducer.

The disadvantage of this device is the complexity of its execution, increased sensitivity to external factors, as well as explosiveness.

The technical result of the invention is an instant determination, light and sound warning, transmission of a signal by radio with a sufficient probability of preventing the consequences associated with a sharp increase in the level of water bodies leading to breakthrough of dams and catastrophes. Figure 1 illustrates the proposed device in General. The sensor contains: a rail with leveling marking 1, electronic metro rod 2, electrodes 3, indicator housing 4, light windows 5, an audible warning device 6, a radio transmitter 7, mounting brackets 8, a protective umbrella 9, mounting racks 10, foundation 11, a protective cover of the device 12, removable hinges 13, the security flap 14, hinges 15, the signal holes of the cover 16, the bottom of the reservoir 17, the middle of the reservoir 18, shore 19.

The device is mounted on a solid foundation and is protected from damage by a thick-walled metal pipe, which is also attached to the foundation. The electrodes of the electronic metro rod are set to a reference mark. When the water rises and the electrodes are immersed in water, an electronic circuit is triggered, the light, sound and radio signals are automatically turned on, which should be recorded by the appropriate services. The siren can be installed at sufficiently large distances from the proposed flooding zones in the hollows of the mountains, in rivers and ponds. On devices installed in ponds located near residential areas, the low speed of raising the water level is monitored by the dashed line of the metro line, the intensive one is monitored by leveling rail, and if the device is in the flood zone, you can watch it with binoculars or level, at night by light check marks.

Figure 2 represents the electronic circuit of the sensor, consisting of a current amplifier on two transistors with galvanic coupling. The sensor’s power source is a 3 V battery or a 12 V battery with a voltage drop through a resistance of up to 3 V and an EMF in the circuit of up to 12 mA.

The ability to repeatedly play a useful model of the sensor of the siren in the water.

Repeated, accurate reproduction of the sensor-signaling device is possible with a slight refinement of the mounting of the electronic metro rod to the leveling rail with the vertical location of the indicator signal housing and the installation of an electronic circuit in it, an audio and radio transmitting device with a constant power supply of 3 or 12 V, with a voltage of up to 1 on the electrodes, 25 V, current up to 0.05 mA, with intrinsic safety below the permissible threshold in the event of gasoline spilling into the river and preventing surface fire. The siren sensor is mechanically strong, not bulky, rigidly fixed and protected from mechanical damage and other influences in places of observation of water level.

The list of essential features of an automatic sensor siren water level in water bodies.

The sensor siren allows you to control the level of rivers and reservoirs in automatic mode. The sensor consists of a staff with leveling markings, on which an electronic metro rod is mounted with a vertically located protective indicator housing, in which, in addition to the electronic circuit, power supply and LED, an audible warning device and a radio transmitting device are built-in.

Mounting the electronic metro rod on the rail allows you to set the control electrodes of the sensor at any calculated level of filling the reservoir with water, especially during emergencies, as well as monitor the rate of filling of the reservoir in close proximity to it, with intensive filling along the rail, and at a great distance from the reservoir using a radio signal . With slow filling, level control can be carried out using a dashed electronic metro line visually or by sound. The sensor electrodes can be located at several expected levels so that there is time not only for emergency warning, but also for the evacuation of the population when it suddenly occurs, for example: five levels from Attention to the announcement of an emergency.

Currently, there are no reliable devices for continuous monitoring of water accumulations in ponds and depressions, especially in mountains located at a considerable distance from settlements.

The proposed device solves the problem of warning about the accumulation of critical masses of water in water bodies and preventing a sudden breakthrough of destructive masses of water, especially at night, notifying upon reaching the critical level of the reservoir, light, sound and radio signals, which can be sent via satellite.

Stationary and portable electronic device sensor announcer of the water level in water bodies, different from analogues:

- the presence of a vertically fixed and protected rail with leveling markings in the floodplain of the reservoir or the proposed drive;

- the presence on the rail of a reliable mounting device, including for electronic metro stock;

- the presence of an electronic metro rod with electrodes protected from damage and a light indicator;

- the presence of an audible alarm;

- the presence of a device transmitting radio signals;
