Description

Technical Field

[0001] This utility model relates to the field of fire extinguishing technology, and in particular to a low-temperature spray extinguishing device for fire fighting. Background Technology

[0002] Firefighting is a systematic project that protects the lives, property, and ecological environment by preventing, monitoring, controlling, and extinguishing fires. When a fire occurs in a thermal power plant, workers usually use water pumps to draw water from the water tank and spray it through sprinklers to extinguish the fire.

[0003] Some problems still exist in the use of existing low-temperature sprinkler fire extinguishing devices for fire fighting. For example, a low-temperature sprinkler fire extinguishing device for fire fighting in a thermal power plant (publication number CN218391981U) uses a rack and pinion to drive a rotating rod through a first gear, which in turn drives a cylindrical cylinder to rotate. By adding liquid nitrogen, it achieves the effect of low-temperature fire extinguishing and facilitates quick adjustment of the nozzle angle and height to cope with fires at different heights and increase the spray range of the fire extinguishing nozzle. However, the rack and pinion are located in an air-exposed position, making them prone to dust accumulation, which increases friction and leads to accelerated surface wear. Therefore, those skilled in the art have provided a low-temperature sprinkler fire extinguishing device for fire fighting to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a low-temperature spray extinguishing device for fire fighting. The device is installed inside a dustproof box through a lifting structure. The lifting structure drives the spraying structure to lift and rotate. The transmission unit on the lifting structure is not affected by dust.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a low-temperature spray fire extinguishing device for fire fighting, comprising a base, a push rod and a control box, wherein the push rod is fixedly connected to the rear end face of the base, the control box is fixedly connected to one side wall of the push rod, a water tank is provided at the rear center of the upper end face of the base, a dustproof box is provided on the upper end face of the base at the front end of the water tank, and a lifting structure is provided at the center of the lower inner wall of the dustproof box;

[0006] The lifting structure includes four synchronous pulleys, with synchronous belts fitted on the outer walls of the four synchronous pulleys. A second servo motor is installed at the lower end of one of the synchronous pulleys. Lead screws are fixedly connected to the upper ends of the four synchronous pulleys. Lifting plates are threaded onto the outer walls of the four lead screws. A rotary joint is fixedly connected to the center of the lower end face of the lifting plate. The rotating end of the rotary joint passes through the lower end face of the lifting plate and extends to the upper end of the lifting plate. A spraying structure is fixedly connected to the end of the rotary joint at the upper end of the lifting plate. A large gear is fixedly fitted on the outer side of the rotating end of the rotary joint at the upper end of the lifting plate. A first servo motor is fixedly connected to the lower end face of the lifting plate on one side of the large gear. The output end of the first servo motor passes through the lower end face of the lifting plate and extends to the upper end face of the lifting plate. A small gear is fixedly connected to the end of the first servo motor.

[0007] A heat-conducting structure is provided on the lower inner wall of the dustproof box near the front.

[0008] With the above technical solution, when height and angle need to be adjusted, the second servo motor is started, driving one of the synchronous pulleys to rotate. This, in turn, drives the other three synchronous pulleys to rotate via a synchronous belt, causing the four lead screws to rotate synchronously and raising the lifting plate. Then, the first servo motor is started, driving a small gear to rotate, which in turn drives a large gear to rotate. The large gear then drives the rotating end of the rotary joint to rotate, thus rotating the spraying structure for both raising and rotating. Finally, the second servo motor is started in the opposite direction, causing the four lead screws to rotate in the opposite direction and lowering the lifting plate. The lifting structure is located inside a dustproof box, and the transmission unit on the lifting structure is not affected by dust.

[0009] Furthermore, the spraying structure penetrates the inner wall of the dustproof box and extends to the upper end of the dustproof box;

[0010] The above technical solution facilitates the raising and lowering of the spraying structure at the top of the dust box.

[0011] Furthermore, the heat-conducting structure includes a heat-insulating shell, inside which heat dissipation fins are provided. A first heat-conducting plate is fixedly connected to the lower end of the heat dissipation fins. The other end of the first heat-conducting plate passes through the heat-insulating shell and extends to the lower end of the first servo motor. A heat-conducting spring is fixedly connected to the upper surface of the first heat-conducting plate located at the lower end of the first servo motor. A heat-conducting seat is fixedly connected to the upper end of the heat-conducting spring. The heat-conducting seat is fixedly connected to the lower end surface of the first servo motor. A second heat-conducting plate is provided on the other side of the lower end surface of the heat-insulating shell. The other end of the second heat-conducting plate is located on the lower end surface of the second servo motor. Both sides of the heat-insulating shell pass through the inner side wall of the dustproof box and extend to the two side walls of the dustproof box.

[0012] Through the above technical solution, during the upward process of the first servo motor, the heat-conducting spring is stretched, and the heat-conducting seat transfers the heat of the first servo motor to the heat dissipation fins through the heat-conducting spring and the first heat-conducting plate. The heat of the second servo motor is transferred to the heat dissipation fins through the second heat-conducting plate.

[0013] Furthermore, two cooling fans are provided on one side of the heat dissipation fins, and dustproof nets are provided at both ends inside the heat insulation shell;

[0014] The above technical solution uses two cooling fans to expel hot air from inside the cooling fins and allows air to enter from the other side to create airflow, continuously dissipating heat. The dust filter prevents dust from entering and accumulating on the cooling fins, thus affecting heat dissipation.

[0015] Furthermore, a water inlet pipe is fixedly connected to the center of the upper end face of the water tank, and a plug is provided inside the water inlet pipe near the upper part;

[0016] The above technical solution allows for easy replenishment of water into the inlet pipe by opening the plug.

[0017] Furthermore, a delivery pump is fixedly connected to the lower center of the front inner wall of the dustproof box, and a spring tube is fixedly connected to the output end of the delivery pump;

[0018] The above technical solution uses a spring tube to connect the rotary joint, which allows for the supply of water during the rising and falling process of the rotary joint.

[0019] Furthermore, a battery module is fixedly connected to the center of the lower end face of the base;

[0020] The above technical solution facilitates the provision of power through the battery module.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the low-temperature spray extinguishing device for fire protection is installed inside the dustproof box through a lifting structure. The lifting structure drives the spraying structure to lift and rotate, and the transmission unit on the lifting structure is not affected by dust.

[0023] 2. In this utility model, during the upward movement of the first servo motor, the heat-conducting spring is stretched, and the heat-conducting seat transfers the heat from the first servo motor to the heat dissipation fins through the heat-conducting spring and the first heat-conducting plate. The heat from the second servo motor is transferred to the heat dissipation fins through the second heat-conducting plate. The two cooling fans are activated, and the two cooling fans exhaust the hot air inside the heat dissipation fins. Air enters from the other side to form an airflow, continuously dissipating the heat and facilitating heat dissipation in a closed environment. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1-4 An embodiment of this utility model is provided: a low-temperature spray fire extinguishing device for fire fighting, including a base 1, a push rod 6 and a control box 13. The push rod 6 is fixedly connected to the rear end face of the base 1, and the control box 13 is fixedly connected to one side wall of the push rod 6. A water tank 5 is provided at the rear center of the upper end face of the base 1. A dustproof box 3 is provided on the upper end face of the base 1 at the front end of the water tank 5. A lifting structure 10 is provided at the center of the lower inner wall of the dustproof box 3.

[0034] The lifting structure 10 includes four synchronous pulleys 1006, with synchronous belts 1007 fitted on the outer walls of the four synchronous pulleys 1006. A second servo motor 1005 is installed at the lower end of one of the synchronous pulleys 1006. Lead screws 1009 are fixedly connected to the upper ends of each of the four synchronous pulleys 1006. Lifting plates 1008 are threaded onto the outer walls of the four lead screws 1009. A rotary joint 1002 is fixedly connected to the center of the lower end face of the lifting plate 1008, with the rotating end of the rotary joint 1002 penetrating through the lifting plate. The lower end of the lowering plate 1008 extends to the upper end of the lifting plate 1008, and a spraying structure 4 is fixedly connected to the end. A large gear 1004 is fixedly sleeved on the outer side of the rotating end of the upper rotary joint 1002 of the lifting plate 1008. A first servo motor 1001 is fixedly connected to the lower end of the lifting plate 1008 on one side of the large gear 1004. The output end of the first servo motor 1001 passes through the lower end of the lifting plate 1008 and extends to the upper end of the lifting plate 1008, and a small tooth is fixedly connected to the end. When the height and angle of wheel 1003 need to be adjusted, the second servo motor 1005 is started. The second servo motor 1005 drives one of the synchronous pulleys 1006 to rotate, and through the synchronous belt 1007, it drives the other three synchronous pulleys 1006 to rotate, thereby causing the four lead screws 1009 to rotate synchronously, raising the lifting plate 1008. Then, the first servo motor 1001 is started, driving the pinion 1003 to rotate, which in turn drives the large gear 1004 to rotate. The large gear 1004 drives the rotating end of the rotary joint 1002 to rotate, thereby driving the spraying structure 4 to rotate, thus raising and rotating. Then, the second servo motor 1005 is started in the opposite direction, causing the four lead screws 1009 to rotate in the opposite direction, lowering the lifting plate 1008. The lifting structure 10 is located inside the dustproof box 3. The lifting structure 10 drives the spraying structure 4 to rise, fall, and rotate. The transmission unit on the lifting structure 10 is not affected by dust.

[0035] A heat-conducting structure 2 is provided on the lower inner wall of the dust box 3 near the front, which facilitates the dissipation of heat under sealed conditions.

[0036] The spraying structure 4 penetrates the inner wall of the dust box 3 and extends to the upper end of the dust box 3, facilitating the raising and lowering of the spraying structure 4 at the upper end of the dust box 3.

[0037] like Figure 1 , 2As shown in Figures 3 and 4, the heat-conducting structure 2 includes a heat-insulating shell 204. Heat-dissipating fins 205 are provided inside the heat-insulating shell 204. A first heat-conducting plate 203 is fixedly connected to the lower end of the heat-dissipating fins 205. The other end of the first heat-conducting plate 203 passes through the heat-insulating shell 204 and extends to the lower end of the first servo motor 1001. A heat-conducting spring 202 is fixedly connected to the upper surface of the first heat-conducting plate 203 located at the lower end of the first servo motor 1001. A heat-conducting seat 201 is fixedly connected to the upper end of the heat-conducting spring 202. The heat-conducting seat 201 is fixedly connected to the lower end surface of the first servo motor 1001. The lower end of the heat-insulating shell 204... A second heat-conducting plate 208 is provided on the other side. The other end of the second heat-conducting plate 208 is provided on the lower end surface of the second servo motor 1005. The heat insulation shell 204 passes through the inner side wall of the dustproof box 3 on both sides and extends to the two side walls of the dustproof box 3. During the rising process of the first servo motor 1001, the heat-conducting spring 202 is stretched. The heat-conducting seat 201 transfers the heat of the first servo motor 1001 to the heat dissipation fins 205 through the heat-conducting spring 202 and the first heat-conducting plate 203. The heat of the second servo motor 1005 is transferred to the heat dissipation fins 205 through the second heat-conducting plate 208.

[0038] Two cooling fans 206 are provided on one side of the heat dissipation fin 205. Dustproof nets 207 are provided at both ends inside the heat insulation shell 204. The hot air inside the heat dissipation fin 205 is exhausted by the two cooling fans 206, and air enters through the other side to form an airflow, continuously dissipating heat. The dustproof nets 207 prevent dust from entering and accumulating on the heat dissipation fin 205, which would affect heat dissipation.

[0039] A water inlet pipe 7 is fixedly connected to the center of the upper end of the water tank 5. A plug 8 is provided at the upper part of the inside of the water inlet pipe 7. Opening the plug 8 makes it easy to add water into the water inlet pipe 7.

[0040] like Figure 2 As shown, a delivery pump 9 is fixedly connected to the lower center of the front inner wall of the dustproof box 3. A spring tube 12 is fixedly connected to the output end of the delivery pump 9. The rotary joint 1002 is connected through the spring tube 12, so that water can be provided during the rising and falling process of the rotary joint 1002.

[0041] A battery module 11 is fixedly connected to the center of the lower end face of the base 1, which facilitates the supply of power.

[0042] Working principle: When in use, water is supplied to the water tank 5 by opening the plug 8, and the base 1 is moved to the required position by pushing the push rod 6. The delivery pump 9 is started by controlling the pump to deliver the water in the water tank 5 to the spring tube 12, and then delivered to the spray structure 4 for spraying through the rotary joint 1002.

[0043] When height and angle adjustments are required, the second servo motor 1005 is started, driving one of the synchronous pulleys 1006 to rotate. This, in turn, drives the other three synchronous pulleys 1006 to rotate via the synchronous belt 1007, causing the four lead screws 1009 to rotate synchronously and raising the lifting plate 1008. Then, the first servo motor 1001 is started, driving the pinion 1003 to rotate. The pinion 1003 then drives the gear 1004 to rotate, which in turn drives the rotating end of the rotary joint 1002 to rotate, thereby rotating the spraying structure 4 for both raising and rotating. Finally, the second servo motor 1005 is started in the opposite direction, causing the four lead screws 1009 to rotate in the opposite direction and lowering the lifting plate 1008.

[0044] During the upward movement of the first servo motor 1001, the thermal spring 202 is stretched. The thermal base 201 transfers the heat from the first servo motor 1001 to the heat sink 205 through the thermal spring 202 and the first thermal plate 203. The heat from the second servo motor 1005 is transferred to the heat sink 205 through the second thermal plate 208. The two cooling fans 206 are activated, and the two cooling fans 206 exhaust the hot air inside the heat sink 205. The air enters from the other side to form an airflow, continuously dissipating the heat and facilitating heat dissipation in a closed environment.

[0045] The control box 13 also includes a communication module and external components. The external components include a temperature sensor to monitor the temperature of key components such as the servo motor and heat sink 205, a pressure sensor to monitor the water pressure inside the water tank 5 to ensure stable water supply, a position sensor to monitor the position of the lifting plate 1008 and the angle of the rotary joint 1002, and a flow sensor to monitor the flow rate of the delivery pump 9 to ensure accurate spraying. The communication module enables communication between the control box 13 and other devices, using industrial fieldbus or wireless communication technology to exchange data. This is a common technique in existing control systems and will not be elaborated on here.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
