When the throwing roller 43 is in a static state, the sand lifting plate 432 on the throwing roller 43 is matched with the sand outlet 411, so that the situation that fire-fighting sand accidentally falls into the power distribution room 1 is reduced; when the throwing roller 43 rotates, fire-fighting sand flows into a section formed between two adjacent sand lifting plates 432 through the sand outlet 411, and is thrown into the distribution room 1 along with the rotation of the throwing roller 43, and fires are extinguished.
Referring to fig. 2, the driving assembly 5 includes a driving motor 51, a driving sprocket 52, a driven sprocket 53, and a chain 54.
The driving motor 51 is installed on the ground in the power distribution room 1, an output shaft of the driving motor 51 is coaxially connected with the driving sprocket 52, the roller shaft 431 passes through the mounting plate 42 and is coaxially connected with the driven sprocket 53, and the chain 54 is wound between the driving sprocket 52 and the driven sprocket 53. The driving motor 51 is in signal connection with the temperature sensor 31 on the same side, and the driving motor 51 is also in signal connection with the smoke detector 32 on the same side.
In the embodiment of the present application, the driving motor 51 is a single-phase asynchronous motor commonly used in the market.
Referring to fig. 2, when the temperature sensor 31 and the smoke detector 32 detect that a fire disaster occurs in the power distribution room 1, the temperature sensor 31 and the smoke detector 32 simultaneously send signals to the driving motor 51 to control the driving motor 51 to start, the driving motor 51 drives the driving sprocket 52 to rotate rapidly, and the movement is transmitted to the driven sprocket 53 through the chain 54, so that the throwing roller 43 is driven to rotate rapidly, fire fighting sand is uniformly thrown into the power distribution room 1, flames burnt in the power distribution room 1 are extinguished, and the fire is controlled.
The implementation principle of the remote safe operation and maintenance system of the distribution room is as follows: when an electrical fire disaster occurs in the power distribution room 1, the detection assembly 3 detects the fire disaster occurring in the power distribution room 1, the control driving assembly 5 drives the sand lifting assembly 4 to start, the sand lifting assembly 4 throws fire prevention sand into the power distribution room 1, and the fire prevention sand is paved at the fire place to isolate air and delay the action of fire. Meanwhile, the air injection assembly 6 is started, a large amount of flame-retardant gas is injected into the power distribution room 1, and the oxygen content in the power distribution room 1 is reduced, so that the purpose of flame retardance is achieved.
By adopting the scheme, workers do not need to enter the distribution room 1 to intervene and process the fire in the process of processing and controlling the electric fire, thereby achieving the purpose of reducing property loss and casualties.
The above preferred embodiments of the present application are not intended to limit the scope of the present application, and therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
