Problems solved by technology
[0003] At present, there is a complete set of devices that automatically monitor the water level and automatically replenish water, but such devices are expensive. Due to reasons such as funding and long project approval period, old pools cannot be renovated in time
There is also a method of using laser or ultrasonic to detect the liquid level of the fire pool, which needs to be installed on the top of the transparent columnar water level indicator of the fire pool. Since the top of the water level indicator is generally more than 3 meters away from the ground, climbing operations are required, and there is a risk of personnel falling risk

Embodiment Construction
[0022] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.
[0023] In the present invention, unless otherwise clearly specified and limited, a first feature being "on" or "under" a second feature may include direct contact between the first and second features, and may also include the first and second features Not in direct contact but through another characteristic contact between them. Moreover, the first feature being "on" the second feature includes the first feature being directly above and obliquely above the second feature, or simply means that the first feature is horizontally higher than the second feature. "Below" the first feature below the second feature includes that the first feature is directly below and obliquely below the second feature, or simply means that the level of the first feature is smaller than that of the second feature.

The invention discloses a low-water-level alarm device for a fire pool. The device comprises a shell, a fixing piece, a detection assembly and an alarm, the fixing part is connected with the surface of the shell, a containing cavity is formed in the shell, the detection assembly comprises a water level sensor, the water level sensor is arranged in the containing cavity, the water level sensor is arranged at the position where the low-water-level warning line is located, the water level sensor is electrically connected with the warning device, and when the water level is lower than the low-water-level warning line, the warning device sends out warning information. The low-water-level alarm device for the fire pool is fixed on the water level indicator through the fixing piece; the fixing position can be flexibly changed, the alarm device is convenient to install, the water level sensor is arranged at the position where the low-water-level warning line is located by selecting a proper fixing position, when the water level is lowered below the low-water-level warning line, the water level sensor sends out a corresponding electric signal, then the alarm is triggered to send out warninginformation, and the alarm device has the advantages of being simple in structure, low in cost and convenient to install and use.
Description
technical field [0001] The invention relates to the technical field of electric power facilities, in particular to a low water level alarm device for a fire-fighting pool. Background technique [0002] At present, the water level of the fire-fighting pool in the substation is mainly displayed by a water-level indicator connected to the fire-fighting pool. Substation inspectors judge the water level of the fire pool by observing the liquid level of the water level indicator. If the water level is low, replenish water to the fire pool. [0003] At present, there is a complete set of devices for automatically monitoring the water level and automatically replenishing water, but this kind of device is expensive. Due to reasons such as funding and long project approval period, old pools cannot be renovated in time. There is also a method of using laser or ultrasonic to detect the liquid level of the fire pool, which needs to be installed on the top of the transparent columnar wa...
