Problems solved by technology

Especially in midsummer, because children are naturally hydrophilic, they often play in the fountain pool in violation of the rules. In this way, they are not only vulnerable to the impact of high-pressure water flow in the fountain, but also in danger of electric leakage from the water pump in the fountain pool. At risk; once the water pump leaks, the children in the pool will bear the brunt of the electric shock, and the guardians who are eager to save the children will often go to the rescue and put themselves in danger. In the end, an irreparable human tragedy will often be staged
In many fountain pool leakage accidents, part of the reason is that the water pump shell is electrified due to the decrease of the insulation of the water pump. Although the power supply system of the fountain pool is equipped with leakage protection devices including air switches, due to improper system maintenance and power supply For various reasons such as unbalanced parameters, the short-circuit current of the leakage pump or other electrical parameters are not enough to make the leakage protection circuit act in time to achieve the effect of cutting off the power supply. Therefore, an effective leakage warning protection device is urgently needed to realize the effective protection of fountains and pools. The role of protection against electric shock

Embodiment 1

[0025] Embodiment 1. In real life, in order to avoid electric shock accidents in the fountain pool 1, on the one hand, it is necessary to formulate strict systems, strengthen safety education, and improve people's safety awareness, especially children; on the other hand, it is also necessary to provide necessary protection; thus, figure 1 , image 3 , Figure 4 , Figure 5 Provides a leakage warning system and warning method in the area of ​​a fountain pool. The fountain pool 1 is usually provided with a pool wall 8 in the ground 7. In the pool surrounded by the pool wall 8, the water pump 6 and the terminal with the water pump 6 are often provided. The probability of electric leakage is relatively high, therefore, the warning device described in this application is adopted. A detection line 5 is also connected, and the detection line 5 includes a free end away from the outer casing 1 and a connection end penetrating into the outer casing 1, and the connection end is connec...

Embodiment 2

[0033] Embodiment two, figure 2 , image 3 , Figure 4 , Figure 5 Among them, after leakage occurs in the water accumulation area 9, when people step into this area, it is easy to cause electric shock accidents due to step voltage. When the step voltage reaches 40-50V, it will cause people to have the risk of electric shock, especially the step voltage It will cause people to fall and increase the electric shock voltage of the human body, and even cause people to be electrocuted to death. Therefore, provide a kind of ground water area 9 electric leakage warning system, it comprises warning device, and described warning device comprises outer casing 1, and the bottom of described outer casing 1 is equipped with detecting pole 2, and in described outer casing 1 One side is also connected with a detection line 5, the detection line 5 includes a free end away from the outer casing 1 and a connection end that penetrates the outer casing 1, and the connection end is connected t...

Abstract

The invention discloses an electric leakage warning system and warning method for a ground water-logging area. The electric leakage warning system comprises a warning device, the warning device comprises an external shell body, the bottom of the external shell body is provided with a detection pole, one side of the external shell body is further connected with a detection line, the detection linecomprises a free end away from the external shell body and a connection end penetrating into the external shell body, the connection end is electrically connected with a control unit located at the upper end of the inner portion of the external shell body, except the free end, the outer portion of a metal guide line connected between the free end and the connection end is provided with an insulating layer, the detection pole is electrically connected with the control unit at the upper end of the inner portion of the external shell body through the guide line, and the control unit is also connected with an audible and visual alarm. According to the electric leakage warning system and warning method for the ground water-logging area, sound and light alarming is adopted for the electric leakage of the water-logging area to achieve a waning function, a protective barrier is added for a traditional electric leakage protective system, therefore, the electric leakage warning system and warning method for the ground water-logging area have a larger application field and prospect.

Description

technical field [0001] The invention relates to an electric leakage warning system and a warning method in a ground water area. Background technique [0002] During the rainy season, the relevant functional departments in the city will always be on the alert and pay close attention to the danger of waterlogging that may occur in every corner of the city, especially if waterlogging occurs on roads, bridges, and low-lying areas, it will cause traffic congestion in the city and cause people's accidents. Also bring great inconvenience. There are many infrastructures in the city, and electricity, municipal water supply and drainage, transportation and other facilities are intertwined. The power lines will inevitably age. life safety. [0003] In addition, in our daily life, we often learn through the media and other channels that there has been an electric leakage accident in a fountain in a certain place, causing people to suffer electric shocks and even die. Especially in mi...
