Automatic drainage system for cable trench accumulated water

Abstract

The invention provides an automatic drainage system for cable trench accumulated water. The automatic drainage system comprises a filtering water channel and a precipitating water channel, wherein the filtering water channel is arranged below a cable trench, the precipitating water channel and the filtering water channel are arranged side by side, a vertical pipeline is arranged between the filtering water channel and the cable trench, and a transverse pipeline is arranged between the filtering water channel and the precipitating water channel. The automatic drainage system further comprises an accumulated water detector, a control device, a drainage pump, a drainage pipe and a water collecting well, wherein the accumulated water detector is fixedly installed on the bottom surface of the cable trench, the accumulated water detector is electrically connected with the control device, and the control device is electrically connected with a switch of the drainage pump; the drainage pump is arranged on the side wall of the precipitating water channel, and the drainage pump communicates with the water collecting well through the drainage pipe; a high-pressure water pump is arranged at one end of the filtering water channel; and the water collecting well communicates with the high-pressure water pump through a pipeline, and filtering impurities in the filtering water channel can be washed away through the high-pressure water pump. According to the automatic drainage system, the filtering water channel and the precipitating water channel are arranged, so that the blockage phenomenon is avoided; and the accumulated water detector is arranged, so that the automatic drainage function is realized when the cable trench has much accumulated water.

Description

technical field [0001] The invention belongs to the technical field of substation maintenance facilities, and in particular relates to an automatic water drainage system for cable trenches. Background technique [0002] With the advancement of technology, the power distribution room of the substation has been unattended, but the problem of water accumulation in the cable trench of the high-voltage room in thunderstorm weather is still a common phenomenon, especially in bad weather such as typhoon and heavy rain. Seawater and rainwater backflow often occur. If the drainage is not timely, it is easy to see the phenomenon that the cables are soaked by water in the cable trench, causing power distribution accidents. [0003] However, as far as the drainage system of the traditional substation cable trench is concerned, the drainage speed will be very slow when the rain is heavy. The main reason is that fallen leaves, sediment, garbage and other debris will enter the cable trench...

Problems solved by technology

[0002] With the advancement of technology, the power distribution room of the substation has been unattended, but the problem of water accumulation in the cable trench of the high-voltage room in thunderstorm weather is still a common phenomenon, especially in bad weather such as typhoon and heavy rain. Seawater and rainwater backflow often occur. If the drainage is not timely, it is easy to see the cable ditch soaked in water and cause power distribution accidents.

[0003] However, as far as the drainage system of the traditional substation cable trench is concerned, the drainage speed will be very slow when the rain is heavy. The main reason is that fallen leaves, sediment, garbage and other debris will enter the cable trench with the water flow. clogged during drainage
