AI Technical Summary
The lack of automated fire protection facilities in underground mines has led to the inability to quickly isolate the fire after the fire occurs, and the spread of the fire is difficult to control.
Design a mine underground fireproof water curtain system, including water sprinkler pipes, water curtain nozzles, smoke sensors and automatic control valves. The smoke sensor monitors the underground tunnels in real time, and the automatic control valve automatically opens the high-pressure water curtain when a fire is detected to isolate the fire.
It has achieved rapid isolation of underground fires in mines, avoided the spread of fires, reduced fire losses, and enhanced fire safety in underground operation sites.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fire prevention in mines, in particular to a fire prevention water curtain underground in mines. Background Art
[0002] In underground mine workplaces, firefighting still relies on traditional facilities such as fire hydrants and fire extinguishers. There are no complete automated firefighting facilities. Once a fire occurs, traditional firefighting facilities cannot respond quickly, and when the fire spreads, it cannot be effectively isolated. Utility Model Content
[0003] In view of the above technical problems, the utility model provides a mine underground fireproof water curtain, which is used to solve the problem that the fire cannot be isolated in the mine underground workplace after a fire occurs.
[0004] In order to achieve the above purpose, the technical solution of the utility model is as follows:
[0005] A fire-proof water curtain for underground mines comprises a water spray pipe, which is horizontally arranged in the vault area of an underground tunnel, and a plurality of water curtain nozzles are vertically downwardly arranged on the water spray pipe, and the water inlet end of the water spray pipe is connected to the high-pressure water inlet pipe. The invention also comprises a smoke sensor and an automatic control valve, wherein the smoke sensor is arranged on the vault of the underground tunnel, and the automatic control valve is arranged on the high-pressure water inlet pipe. The normally open contact of the smoke sensor is connected in series with the starting part of the automatic control valve, and the water inlet end of the high-pressure water inlet pipe is connected to two water supply branches, one of which is provided with the automatic control valve, and the other is provided with a manual switch, and the water curtain nozzles are rotatably mounted on the water spray pipe.
[0006] Compared with the prior art, the utility model has the following beneficial effects: the utility model has a simple structure and strong practicality. When a fire occurs, water is sprayed downwards through the water curtain nozzle to form a water curtain, which effectively isolates the fire and prevents the fire from spreading. The smoke sensor monitors the underground tunnels in real time. When a fire occurs, the smoke sensor transmits a signal to the automatic control valve, and the automatic control valve opens to automatically isolate the fire at the first time, minimizing the fire loss. The high-pressure water inlet pipe is designed with manual and automatic opening modes, which enhances operability and avoids untimely fire isolation after the automatic control valve fails. The adjustable water curtain nozzle enhances adjustability, and the water curtain nozzle can be set at a certain angle according to the actual situation on site. BRIEF DESCRIPTION OF THE DRAWINGS
[0007] Figure 1 It is a structural schematic diagram of the utility model;
[0008] Figure 2 It is an enlarged structural schematic diagram of the figure number 4 in the present utility model.
[0009] In the figure:
[0010] 1. Underground tunnel; 3. Water curtain nozzle; 4. Water spray pipe; 5. Smoke sensor; 6. Automatic control valve; 7. High-pressure water inlet pipe; 8. Manual switch. DETAILED DESCRIPTION
[0011] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.
[0012] A fire-proof water curtain for underground mines, comprising a water spray pipe 4, the water spray pipe 4 being horizontally arranged in the vault area of an underground tunnel 1, a plurality of water curtain nozzles 3 being vertically arranged downward on the water spray pipe 4, the water inlet end of the water spray pipe 4 being connected to a high-pressure water inlet pipe 7, and also comprising a smoke sensor 5 and an automatic control valve 6, the smoke sensor 5 being arranged on the vault of the underground tunnel 1, the automatic control valve 6 being arranged on the high-pressure water inlet pipe 7, the normally open contact of the smoke sensor 5 being connected in series with the start part of the automatic control valve 6, the smoke sensor 5 monitoring the underground tunnel 1 in real time, and when a fire occurs, the smoke sensor 5 transmitting a signal to the automatic control valve 6 Control valve 6, the automatic control valve 6 is opened, the fire is automatically isolated in the first time, and the fire loss is minimized. The water inlet end of the high-pressure water inlet pipe 7 is connected to two water supply branches, one water supply branch is provided with the automatic control valve 6, and the other water supply branch is provided with a manual switch 8. The high-pressure water inlet pipe 7 is designed with manual and automatic opening modes, which enhances operability and avoids the failure of the automatic control valve 6, which leads to untimely fire isolation. The water curtain nozzle 3 is rotatably installed on the water pipe 4, which enhances adjustability and can be set to a certain angle according to the actual situation on site.
[0013] When the utility model is in use, once a fire occurs underground, the smoke sensor 5 will receive a signal and connect the automatic control valve 6 on the high-pressure water inlet pipe 7. After the automatic control valve 6 is opened, high-pressure water is sprayed out through the water curtain nozzle 3 to form a fire-proof water curtain. If the smoke sensor 5 fails after a fire occurs, the underground operator can open the manual switch 8, which can also allow the high-pressure water to reach the water curtain nozzle 3 to form a fire-proof water curtain, so as to achieve the purpose of isolating the fire.
[0014] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
