Description

Automatic water level alarm device for cable trench in power distribution room

technical field

The utility model relates to an automatic water level alarm device, in particular to an automatic water level alarm device for a cable trench in a power distribution room.

Background technique

The cable trench is an underground special channel for laying cables. Usually, there is a cable trough frame in the cable trench for placing cables. There is still a certain distance between the trough frame and the bottom of the trench. The cable trench can be divided into outdoor and indoor. The outdoor part generally has corresponding drainage measures, and the indoor part is not easy to drain. The main purpose is to prevent water from entering the trench as much as possible. Indoor cable trenches, especially those in power distribution rooms, are above the cables for power supply equipment. Once water accumulates in the trench and the water level rises, it will have a major impact on the cables and even the power supply equipment, resulting in power outages and other abnormal accidents. In real life, there are frequent accidents caused by water storage in the cable ditch of the power distribution room due to heavy rain or mis-drainage, which has a great impact on the daily life of residents and increases the workload of inspection and maintenance.

detailed description

The technical scheme of the utility model will be further described below with reference to the accompanying drawings and specific embodiments.

As shown in Figure 1 and Figure 2, the utility model provides an automatic alarm device for cable trench water level in a power distribution room, including a water immersion sensor 21, a transmitter 22, a central processing unit 23 and a communication module 24, and the cable trench 1 is equipped with There is a cable trough 2, and the cable trough 2 is installed on the side wall of the cable trough 1, and one or more water immersion sensors 21 are arranged in the cable trough 1, and the water immersion sensors 21 are all installed at the lowest position of the cable trough 2 and Between the bottom of the cable trench 1 , the water immersion sensor 21 is connected to a transmitter 22 , the transmitter 22 is connected to a central processing unit 23 , and the central processing unit 23 is connected to a communication module 24 . The central processing unit is preferably a single-chip microcomputer, and the communication module 24 is preferably a GPRS module.

The working principle and process of the utility model are as follows: when there is no water in the cable trench 1 or the water level does not reach the water immersion sensor 21, the water immersion sensor 21 is in a normally open state, and then an electrical signal in a normal state is sent out, and the electrical signal passes through the transmitter 22 after amplifying, import in the central processing unit 23, can not give an alarm now; The signal is amplified by the transmitter 22 and transmitted to the central processing unit 23, and the central processing unit 23 controls the communication module 24 to communicate after receiving the electrical signal, and the client can receive the alarm. The client can be installed in the computer in the monitoring room or installed on the mobile phone of the monitoring personnel in the form of APP software. The water immersion sensor 21 can be provided with multiple groups in the cable trench 1, installed in different positions and set with different numbers. When an alarm is issued, the alarm location can be determined quickly according to the number transmitted by the communication module 24, so as to take corresponding drainage emergency measures. Measures, such as using a temporary drainage pump, forcibly discharge the water stored in the flooded cable trench 1, so as to prevent problems before they happen. In addition, the device has a self-inspection function. The central processing unit 23 detects the transmitter 22 every 5 minutes. If the transmitter 22 is detected to be in a "normal" state, the control communication module 24 sends a "normal" signal to the monitoring room. If it is detected that the transmitter 22 is in an "alarm" state, then the control communication module 24 sends an "alarm" signal to the monitoring room, and sends a short message to the mobile phone of the monitoring personnel. If the central processing unit 23 cannot detect the transmitter 22 signal, then The control communication module 24 sends a "device abnormality" signal to the monitoring room, and sends a short message to the mobile phone of the monitoring personnel to ensure that the sensors and corresponding wired or wireless lines are operating normally and prevent false alarms from occurring.

After the device is running, the monitoring personnel can send information to the alarm device at any time to inquire about the health status of the device, and the device will immediately report its health and operating status to the monitoring personnel according to the content of the information. In addition, the water immersion sensor 21 can also detect the water level condition, and the central processing unit 23 can also send the water level condition to the monitoring room and the mobile phone of the monitoring personnel through the communication module 24. In actual use, the pre-alarm line and the alarm line can be set according to the needs, which is safe. Sex is higher.

From the above description, it can be found that the utility model can detect the water level depth in the cable ditch online, and feed back to the monitoring room and the mobile phone of the monitoring personnel at any time, effectively avoiding damage to the power supply equipment due to water accumulation; when an alarm is issued, it can be accurately positioned, It is convenient for maintenance personnel to overhaul; in addition, the utility model also has a self-check function to prevent false alarms and make the operation of the device more reliable.

Of course, the above are only typical examples. In addition, the utility model can also have other various specific implementation modes. All technical solutions formed by equivalent replacement or equivalent transformation all fall within the scope of protection required by the utility model. .
