[0026] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0027] Embodiment 1: A high-rise emergency lighting and evacuation indication system, comprising an emergency control module and a lighting evacuation device, wherein the emergency control module comprises a power module, a control module and an emergency module, wherein the emergency module comprises a water supply unit and a smoke exhaust unit, wherein the water supply unit comprises a water delivery pipeline, a control valve, a flow meter, a pressure gauge, a booster pump and a water tank; wherein the smoke exhaust unit comprises an exhaust fan, a smoke exhaust main pipeline and a smoke exhaust branch pipeline; By providing a power module, the control module can be powered to provide the electricity it needs for daily use. The water supply unit can provide water support in the event of a fire. The smoke exhaust unit can promptly discharge smoke from the high-rise internal area to the external area when a fire occurs, thereby guiding and transferring the smoke.

[0028] The water pipeline and the control valve are connected by bolts and flanges. The water pipeline is distributed at the ceiling of a high-rise building and supported by a truss. A flow meter is used to detect the flow rate of water in the water pipeline, and a pressure gauge is used to monitor the water pressure. For the problem of insufficient water pressure in high-rise buildings, a stainless steel water tank is installed on the top of the high-rise building to store water. The exhaust fan is fixed on the top of the high-rise building, and a through-type smoke exhaust main pipeline is arranged inside the high-rise building, smoke exhaust branch pipelines are arranged between each floor, and the smoke exhaust branch pipelines and the smoke exhaust main pipeline are connected by a connecting pipe.

[0029] Embodiment 2: A high-rise emergency lighting and evacuation indication system, such as Figures 1 to 6 As shown, the lighting evacuation device includes a transparent shell 1, an indicator and a cleaning component, and the cleaning component includes: Cover plate 3: It is fixed to the top of the transparent housing 1 by screws, and the inner wall of the through hole opened on the surface of the cover plate 3 is fixed with a water inlet pipe 9 by embedding; Solenoid valve 25: It is connected to the outer wall of the water inlet pipe 9 through threads, and one end of the solenoid valve 25 away from the water inlet pipe 9 is connected to the connecting pipe 10 through threads; Hollow tube 8: It is welded to one end of the connecting tube 10; The compression rod 28 is slidably connected to the inner wall of the through hole opened at the bottom of the hollow cylinder 8, and the bottom and top of the compression rod 28 are respectively fixed with a push plate 27 and a bottom plate 22 by pins; Spring 29: It is sleeved on the circumferential outer wall of the compression rod 28, and the two ends of the spring 29 are respectively fixed to the top outer wall of the bottom plate 22 and the bottom outer wall of the hollow cylinder 8 by pins; Nozzle 26: It is connected to the outer wall of the bottom of the hollow cylinder 8 through threads; Conical scraper 2: It is fixed to the bottom of the bottom plate 22 by a pin, and the inner diameter of the conical scraper 2 and the outer diameter of the transparent housing 1 are adapted to each other; The transparent shell 1 is provided to accommodate the indicating part, and a certain protection is provided to the indicating part. Since the transparent shell 1 needs to be placed in an external environment after installation, dust will adhere to the outer surface of the transparent shell 1, and the dust will affect the clarity of the indicating part when performing evacuation indication. When it is necessary to clean the outer wall of the transparent shell 1, the water inlet pipe 9 and the fire water pipe are connected, and the solenoid valve 25 is opened so that the water is pressurized and introduced into the connecting pipe 10 through the solenoid valve 25, and the upper surface of the push plate 27 is pushed by the water pressure. In this process, the compression rod 2 8 moves down along the hollow cylinder 8, and the water is finally sprayed onto the outer surface of the transparent shell 1 through the nozzle 26 after being pressurized, and the water is received by the conical scraper 2. The part where the conical scraper 2 contacts the transparent shell 1 is wrapped with rubber. The water wets the outer wall of the transparent shell 1 through the gap between the rubber and the transparent shell 1, and the conical scraper 2 scrapes off the dust attached to the outer wall of the transparent shell 1 during the process of moving up and down along the outer wall of the transparent shell 1 under the push of the water pressure, thereby cleaning the outer wall of the connecting pipe 10, thereby preventing the dust from affecting the clarity of the indicating part; When the water supply to the connecting pipe 10 is stopped, the push plate 27 is pushed up along the inner wall of the hollow cylinder 8 by the rebound force of the spring 29 to squeeze out the remaining water in the hollow cylinder 8 through the nozzle 26, thereby preventing water from accumulating in the hollow cylinder 8.

[0030] Further, the indicating part includes a partition 12, an arrow light 13 and an emergency lighting lamp 14, the partition 12 is integrally formed on the bottom inner wall of the transparent shell 1, and an installation chamber is formed between the partition 12 and the transparent shell 1, and the arrow light 13 and the emergency lighting lamp 14 are both fixed to the inner wall of one side of the partition 12 by screws; the indicating part also includes a battery 11 fixed to the bottom inner wall of the transparent shell 1, and the battery 11 and the arrow light 13 and the emergency lighting lamp 14 are electrically connected; Under normal conditions, the power grid is used to power the arrow light 13, and the arrow light 13 can indicate the safe evacuation passage to ensure that senior personnel evacuate in the direction indicated by the arrow light 13. When an emergency situation occurs and the power grid needs to be cut off, the battery 11 is used to power the arrow light 13 and the emergency lighting lamp 14 at the same time. The emergency lighting lamp 14 can play a lighting role after the power grid is cut off, thereby providing lighting for the evacuation of senior personnel. By embedding the arrow light 13 and the emergency lighting lamp 14 inside the installation chamber formed by the transparent shell 1 and the partition 12, dust accumulation on the surface of the arrow light 13 and the emergency lighting lamp 14 can be effectively avoided, thereby ensuring the cleanliness of the surfaces of both.

[0031] Further, the inner wall of the through hole opened at the bottom of the transparent shell 1 is rotatably connected with a rotating tube 17, the bottom of the water inlet pipe 9 is fixed with a solenoid valve 15 by bolts, and the bottom of the solenoid valve 15 and the top of the rotating tube 17 are rotatably connected, the outer wall of the bottom of the rotating tube 17 is welded with a rotating plate 7, and the outer wall of the rotating plate 7 is welded with a side plate 6, and the two side plates 6 are rotatably connected with a nozzle 19 through a rotating shaft 21, and a connecting pipe 20 is connected between the nozzle 19 and the outer wall of the rotating tube 17 through a joint; When a fire occurs in a high-rise building, the solenoid valve 15 is controlled to open and the solenoid valve 25 is closed, so that the water inlet pipe 9 inputs water into the rotating tube 17 and finally sprays it out through the nozzle 19, so that the fire in the high-rise corridor can be extinguished, thereby quickly suppressing the fire. By arranging the nozzle 19 in a ring shape on the outer wall of the rotating plate 7, water can be sprayed from different directions to increase the fire extinguishing range.

[0032] Furthermore, a transverse plate 24 is fixed to the inner wall of one side of the partition 12 by bolts, and a driving motor 16 is fixed to the outer wall of the top of the transverse plate 24 by bolts, and a pulley 18 is fixed to the output end of the driving motor 16 and the outer wall of the circumference of the rotating tube 17 by pins, and the two pulleys 18 are driven by a synchronous belt 23; The rotating tube 17 can rotate by utilizing the transmission effect of the pulley 18 and the synchronous belt 23. During the rotation process, the rotating tube 17 utilizes the centrifugal force to accelerate the rate at which water is sprayed out of the nozzle 19. At the same time, the inclination angle of the nozzle 19 relative to the side plate 6 is adjusted by adjusting the rotation speed of the rotating tube 17. In the initial stage, the nozzle 19 remains vertical to the horizontal plane under the action of its own gravity. When the rotating tube 17 drives the nozzle 19 to rotate, the nozzle 19 will rotate relative to the rotating shaft 21 under the action of centrifugal force. By controlling the rotation speed of the rotating tube 17, the size of the centrifugal force is adjusted, and then the inclination angle of the nozzle 19 is adjusted.

[0033] Furthermore, a mounting plate 4 is fixed to the top outer wall of the cover plate 3 by bolts; The entire lighting evacuation device can be suspended on the top of the ceiling using the mounting plate 4.

[0034] Furthermore, a smoke alarm 5 is fixed to the top outer wall of the cover plate 3 by bolts; The smoke alarm 5 is provided to give an alarm when a fire occurs, so as to remind the high-level personnel to evacuate in time.

[0035] When the present embodiment is in use, under normal circumstances, the power grid is used to power the arrow light 13, and the arrow light 13 can indicate the safe evacuation passage to ensure that the senior personnel are evacuated in the direction indicated by the arrow light 13. When an emergency occurs, the connection with the power grid is disconnected, and the battery 11 is used to power the arrow light 13 and the emergency lighting lamp 14 at the same time. The emergency lighting lamp 14 can play a role in lighting after the power grid is cut off, thereby providing lighting for the evacuation of senior personnel; when a fire occurs, the solenoid valve 15 is opened, so that the water is pressurized and transported to the rotating tube 17 through the water inlet pipe 9, and finally the fire is extinguished through the rotating tube 17 and the nozzle 19.

[0036] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
