Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting water cannons, in particular to an automatic fire-fighting water cannon used for extinguishing fires in cinemas. Background Art

[0002] The automatic fire-fighting water monitor uses flame sensors to perform computational amplification and analytical processing on the ultraviolet waves and infrared waves unique to flames, thereby realizing red-ultraviolet dual-band composite fire detection, which has high stability and reliability. When a fire occurs, after the fire source is found through dual-band detection, the central controller will adjust the relative position of the high-pressure nozzle. After the high-pressure nozzle is aimed at the fire source, the solenoid valve will be opened to allow water to spray out from the high-pressure nozzle to accurately extinguish the fire.

[0003] During the use of automatic fire water cannon, it is necessary to ensure that the electronic control system is intact, but the automatic fire water cannon used for theater fire extinguishing is in standby mode for a long time, and the startup interval may sometimes be as long as two or three years. Therefore, the solenoid valve connected to the fire water cannon may have aging failure due to long installation time. When the infrared detector of the fire water cannon finds the fire source, although the central controller transmits the command to open the solenoid valve, the solenoid valve cannot be opened normally due to aging and other failures of the electronic valve itself. Therefore, it is necessary to develop a fire water cannon with a backup switch valve to provide better safety protection for users. Utility Model Content

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1 , an automatic fire-fighting water cannon for extinguishing fire in cinemas, comprising an automatic fire-fighting water cannon 1, also known as an automatic tracking and positioning jet fire-fighting device, which organically combines infrared sensing technology, signal processing technology, communication control technology, computer technology and mechanical transmission technology, and can automatically detect fires within a protection range around the clock. Once a fire occurs in a cinema, the device is immediately activated to spray water to extinguish the fire source. The water spray shape of the fire-fighting water cannon is columnar water, which has the advantages of long range, wide protection range and high precision. The automatic fire-fighting water cannon 1 is connected to a main pipe 2, which is connected to a fire-fighting water pipe, and an electromagnetic valve is arranged on the main pipe 2, and a spare pipe is connected to the main pipe 2;

[0018] The standby pipe includes a connecting pipe 3 and a tapered pipe 4. The connecting pipe 3 and the tapered pipe 4 are an integrally formed structure. The tapered pipe 4 is connected with a water inlet pipe 5. The tapered pipe 4 is provided with a blocking structure. The other end of the connecting pipe 3 is connected with a fire water pipe. Water is injected into the standby pipe through the water inlet pipe 5. The tapered pipe 4 can be assisted by the blocking structure.

[0019] The automatic fire-fighting water monitor 1 is provided with a temperature sensor 6 for monitoring the temperature in the theater;

[0020] The blocking structure includes a conical block 7 that matches the inner cavity of the conical tube 4. The flat end of the conical block 7 is connected to a first driving member 8. The first driving member 8 specifically adopts an electric push rod. The movable end of the first driving member 8 slides through the side wall of the conical tube 4. The specific model and working principle are well known to those skilled in the art and will not be described in detail here. As shown in the figure, the conical block 7 is driven to move to the left by the first driving member 8 to assist the conical tube 4 to prevent water in the conical tube 4 from flowing into the connecting tube 3.

[0021] Since the conical block 7 is in contact with the inner wall of the conical tube 4 for a long time, the contact point is prone to rust. The first driving member 8 is connected to the second driving member 9 through a connecting plate. The second driving member 9 is installed on the outer wall of the conical tube 4. The second driving member 9 specifically adopts a motor. The specific model and working principle are well known to people in this field and will not be repeated here. The motor drives the electric push rod to rotate, thereby rotating the conical block 7 to avoid rusting due to contact between the conical block 7 and the inner wall of the conical block 7, which affects the movement of the conical block 7.

[0022] The lower wall of the connecting pipe 3 is connected to a water distribution pipe 10, and the water distribution pipe 10 is connected to a water collecting tank 11. The water collecting tank 11 is provided with a cleaning door. The water collecting tank 11 adopts a transparent structure, such as a transparent plastic material. The water that enters the connecting pipe 3 through the connection between the conical block 7 and the conical pipe 4 enters the water collecting tank 11 through the water distribution pipe 10 to be collected, thereby preventing the water from flowing into the automatic fire-fighting water cannon 1 and causing the automatic fire-fighting water cannon 1 to leak.

[0023] An anti-backflow structure is also provided in the connecting pipe 3, and the anti-backflow structure includes a baffle 12 matching the inner wall of the connecting pipe 3, the baffle 12 is rotatably connected to the inner wall of the connecting pipe 3, and a block 13 is provided at the lower end of the baffle 12, and the block 13 is installed on the inner wall of the connecting pipe 3. The anti-backflow structure can prevent the water in the main pipe 2 from flowing back into the conical pipe 4 through the connecting pipe 3, and when water is replenished through the connecting pipe 3, the water flow hits the baffle 12, so that a gap is generated between the baffle 12 and the connecting pipe 3, and water passes through the gap.

[0024] Embodiment: After a fire occurs in a cinema, the infrared detector on the automatic fire-fighting water monitor 1 senses the fire and feeds back the information to the central processor. The central processor then controls the nozzle to rotate and adjusts the angle of the high-pressure nozzle. Then, the electromagnetic valve on the side of the main pipe 2 connected to the fire-fighting pipe is controlled to open so as to direct the high-pressure water flow into the main pipe 2. However, if the electromagnetic valve fails at this time, the electromagnetic valve is located at the upper end of the spare pipe and cannot be opened. The temperature in the cinema continues to rise. When the temperature around the temperature sensor 6 rises to a certain level, the signal is transmitted to the controller. The controller is used to control the first and second drive members and control the first drive member 8 to work. As shown in the figure, the conical block 7 moves to the right, so that a gap is formed between the conical block 7 and the inner wall of the conical pipe 4, so that water enters the connecting pipe 3. At this time, the inside of the spare pipe is restored to be unobstructed, and the high-pressure water flow of the fire-fighting pipe can enter the spare pipe through the water inlet pipe 5, and then enter the main pipe 2. Finally, the high-pressure water flow is ejected from the high-pressure nozzle to spray water on the fire point in the cinema, thereby extinguishing the fire point.

[0025] The controller is also provided with a timer. At regular intervals, for example, three months, the controller controls the second driving member 9 to rotate, thereby controlling the rotation of the conical block 7 to prevent the conical block 7 from rusting with the inner wall of the conical tube 4, causing the conical block 7 to be unable to move left and right.
