Description

Technical Field

[0001] The utility model relates to the technical field of electric power base stations, in particular to an electric power base station fire fighting device for electric power engineering. Background Art

[0002] Power engineering refers to engineering related to the production, transmission and distribution of electric energy. In a broad sense, it also includes engineering that uses electricity as power and energy in multiple fields. At the same time, it can be understood as power transmission and transformation engineering. The production of electric energy mainly relies on thermal power plants, hydropower stations and nuclear power plants. In places with conditions, tidal, geothermal and wind energy are also used to generate electricity. The transmission and distribution of electric energy is mainly achieved through high and low voltage AC power networks. In the process of power transmission in power engineering, it is often necessary to establish a power base station. In order to ensure fire safety, fire fighting equipment is often required to be installed in the power base station.

[0003] When a fire occurs, the burning of the insulating rubber on the outer layer of the wires in the power project will first produce toxic smoke, and only when it reaches a certain temperature will the carbon burn, thus producing an open flame.

[0004] However, the fire-fighting devices of some power base stations are only equipped with fire-fighting pipelines, which have low sensitivity to smoke detection and poor detection effect. When a fire occurs, an alarm cannot be issued in the first time. Therefore, we propose a fire-fighting device for a power base station for power engineering to solve the above problems. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fire-fighting device for a power base station used in an electric power engineering project, comprising a fire-fighting cabinet, a box body is fixedly connected to the top inner wall of the fire-fighting cabinet, a laser generator is fixedly connected to the top inner wall of the box body, a laser receiver and a photoelectric sensor are fixedly connected to the bottom inner wall of the box body, a transparent tube and a square rod are fixedly connected between the left and right inner walls of the box body, an annular cleaning block is slidably connected to the outside of the transparent tube, connecting blocks are fixedly connected to the upper and lower sides of the annular cleaning block, a screw is rotatably connected between the left and right inner walls of the box body, the upper connecting block is threadedly connected to the screw rod, and the lower connecting block is slidably sleeved on the outside of the square rod, and a multi-level alarm and a warning light are fixedly connected to the top of the fire-fighting cabinet.

[0007] Further preferably, a motor is fixedly connected to the right side of the box body, and the end of the output shaft of the motor is fixedly connected to the right end of the screw rod.

[0008] Further preferably, an induced draft fan is fixedly connected to the top inner wall of the fire cabinet, and an air inlet of the induced draft fan is connected to an air inlet duct.

[0009] Further preferably, the left end of the air inlet pipe is connected to a deflector cover, and the air outlet of the induced draft fan extends into the box body and is connected to the transparent tube.

[0010] Further preferably, the right end of the transparent tube is connected to a discharge pipe, and the right end of the discharge pipe extends to the outside of the right side of the fire cabinet.

[0011] Further preferably, a plurality of dry fire extinguishers are placed at the bottom of the fire cabinet.

[0012] Further preferably, a glass window is embedded on the front side of the fire cabinet.

[0013] Compared with the prior art, the utility model has the following beneficial effects: the utility model induced draft fan works by conveying air through the air inlet pipe to the transparent tube through the air guide cover, and then the air is discharged through the exhaust pipe. When a fire occurs, the smoke in the air enters the glass tube, and the laser signal emitted by the laser generator is blocked by the smoke, so that the laser receiver cannot receive the laser signal, and the warning light is on. As the smoke concentration increases, the laser signal emitted by the laser generator will be scattered on the top of the photoelectric sensor due to the diffusion effect of the smoke, and the photoelectric sensor controls the multi-level alarm to emit a corresponding frequency according to the brightness of the received laser signal. The staff can open the fire cabinet and take out the dry fire extinguisher inside to put out the fire. The glass window is set to facilitate emergency window breaking when the fire cabinet cannot be opened. Similarly, when the transparent tube is covered with stains, the warning light will also light up, start the motor, and the output shaft of the motor drives the screw to rotate. The screw drives the annular cleaning block through the connecting block to clean the outside of the transparent tube, so as to detect whether there is smoke in the air in the area. At the same time, it can automatically clean the glass tube used for detection, improve the sensitivity of detection, and issue an alarm as soon as a fire occurs. BRIEF DESCRIPTION OF THE DRAWINGS
