Abstract
Description
Technical Field
[0001] This utility model relates to the fields of intelligent mechanization and intelligent fire protection technology, and in particular to a multifunctional telescopic automatic fire extinguishing device. Background Technology
[0002] Workshops such as machining workshops and electronic equipment manufacturing workshops contain a large number of mechanical equipment and electrical wiring, which may cause fires due to equipment failure or electrical short circuits. Multifunctional telescopic automatic fire extinguishing devices can flexibly adjust their position and height according to the layout of the workshop and the distribution of equipment, and carry out targeted fire extinguishing operations in different areas to quickly control the spread of fire.
[0003] In some existing automatic fire extinguishing devices, the control system receives electrical signals from the detection system and processes and analyzes them. It comprehensively considers signals from multiple sensors to determine whether a fire has actually occurred, thus avoiding false alarms. For example, it may only start spraying water when the smoke sensor and temperature sensor simultaneously emit abnormal signals, and the heat-sensitive sprinkler head only starts spraying water when the temperature exceeds 68°C. In such scenarios, it is difficult to extinguish the fire.
[0004] Currently, most intelligent fire extinguishing equipment is outdoor mobile, with a smaller portion being indoor fixed. Outdoor mobile equipment is expensive, cannot reach indoor fire points, and has limited practical value compared to professional fire trucks. Indoor fixed equipment improves detection and response capabilities but lacks mobility. Insufficient mobility makes large-scale use economically inefficient.
[0005] However, in practical use, most common tank fire extinguishing devices are portable fire extinguishers, pipeline fire extinguishers, handheld fire extinguishers, or temperature-sensitive nozzles. These devices have fixed layouts, slow response times, low fire extinguishing efficiency, insufficient mobility, and pose significant risks to operators, creating certain safety hazards. Furthermore, when a fire reaches the set fire extinguishing procedure, personnel cannot approach the fire extinguisher, making manual handheld fire extinguishing virtually impossible. In almost every fire, firefighters must travel from a great distance to carry out effective fire extinguishing operations, which also poses significant risks to firefighters. To address the above-mentioned problems, a multi-functional telescopic automatic fire extinguishing device is proposed. Utility Model Content

[0016] As a further description of the above technical solution:
[0017] The medium storage container and the drive lifting mechanism are joined together with mortise and tenon joints. The male tenon of the electric universal wheel plate base is fixed to the medium storage container. The four corners of the male tenon of the electric universal wheel plate base are provided with holes with buckles.

[0026] This utility model has the following beneficial effects:
[0027] 1. In this utility model, by pressing and rotating the locking plate, the locking plate can compress the telescopic rod, causing the spring outside the telescopic rod to deform. This allows the locking plate to separate the locking rod from the slot outside the connecting block. Then, by pulling the slot, the suction cup can be adjusted. The suction force and angle of the suction cup can be precisely adjusted according to different installation surfaces, such as rough cement walls, smooth glass, or irregular metal surfaces, to ensure a tight fit with the installation surface. This ensures that the fire extinguishing device is firmly fixed in the required position, preventing loosening or falling off during use.
[0028] 2. In this invention, the push tube delivers the extinguishing agent to the nozzle and sprays it out, aiming it at the fire source for extinguishing. During the extinguishing process, the push tube can extend and retract according to the position of the fire source, which is accomplished by the cylinder and the push rod. Simultaneously, the hollow rotary joint and the swing-up base can swing freely within a certain angle range, allowing the extinguishing device to cover a larger extinguishing area. The multiple extendable nozzles can flexibly adjust the distance and height according to the fire source position and switch nozzles based on the fire source image. In complex environments, such as tall buildings or warehouses with multi-layered shelving, the lifting mechanism allows for more precise approach to the fire source, ensuring the extinguishing agent acts directly on the ignition point, improving extinguishing efficiency and quickly controlling the spread of the fire.
[0029] 3. In this utility model, when the multifunctional telescopic automatic fire extinguishing device is fixedly suspended indoors, the fire-spraying actuator faces downwards, and the height of the spray gun is adjusted by the lifting bracket at the bottom of the tank; when the automatic fire extinguishing device is used for external support operations at the fire source, the drone is connected to the tank base and suspended for flight, the drone is controlled to go to the fire scene, the drone performs lifting operations, and the fire extinguishing device automatically adjusts the direction of the spray gun to extinguish the fire.
[0030] 4. In this utility model, when the multi-functional telescopic automatic fire extinguishing device is fixed indoors, the fire-spraying actuator faces upwards, and the base at the bottom of the tank quickly engages with the indoor structure, allowing the automatic fire extinguishing device to rotate 360° for inspection and operation; when the multi-functional telescopic automatic fire extinguishing device is mobile indoors, the electric casters automatically locate the fire source and rush to extinguish the fire according to the positioning signal command.
[0031] 5. In this utility model, when the multifunctional telescopic automatic fire extinguishing device is used in conjunction with mobile objects such as automobiles, ships, electric motorcycles, and aircraft, the tank for storing the medium is shaped according to the space of the equipment, the hose between the solenoid valve and the nozzle is extended, one set protects the equipment compartment operated by personnel, one set protects the power supply compartment, and the spare spray gun is used for mobile operations.
[0032] 6. When used for fixed suspension, flight suspension, wall mounting, or cabinet mounting operations, the suction cup and electric telescopic pole are connected in combination.

[0041] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0042] Reference Figures 1 to 3This utility model provides an embodiment of a multifunctional telescopic automatic fire extinguishing device, including a medium storage container 1. The medium storage container 1, as the core component of the fire extinguishing device, stores the gases required for fire extinguishing, such as carbon dioxide and dry powder. A support 2 is fixedly connected to the bottom of the medium storage container 1. The support 2 is constructed from high-quality metal profiles, forming a frame structure that provides stable support for the entire fire extinguishing device. Electric telescopic rods 3 are fixedly connected to the four corners of the bottom of the support 2. The electric telescopic rods 3 employ advanced motor drive technology, allowing for precise adjustment of their extension and retraction length via a control system to adapt to different fire extinguishing scenarios. The drive end of the retractable rod 3 is fixedly connected to an electric universal wheel flat base 4. The electric universal wheel flat base 4 is made of high-strength rubber material, which has good wear resistance and steering flexibility. Each universal wheel is equipped with an independent braking device, which can quickly lock after the fire extinguishing device reaches the designated position to prevent the device from moving. The bottom of the bracket 2 is fixedly connected to an adjustment mechanism. The top of the medium storage container 1 is fixedly connected to a hollow electric rotary joint 15. The hollow electric rotary joint 15 is equipped with a precision rotary sealing component inside, which can achieve 360-degree free rotation after the power is turned on, while ensuring the stable delivery of gas in the pipeline and avoiding gas leakage.
[0043] A three-way solenoid valve 16 is fixedly connected to the top of the hollow electric rotary joint 15. The three-way solenoid valve 16 is a key component for controlling the gas flow direction. It has three interfaces. By electromagnetically controlling the opening and closing state of the valve core, the output direction of the gas can be flexibly switched to achieve precise delivery of fire extinguishing gas. A fire extinguishing actuator is fixedly connected to the top of the three-way solenoid valve 16. The fire extinguishing actuator includes a push tube 20. The push tube 20 is made of high-strength, high-pressure resistant metal tubing with a smooth interior, which can effectively reduce the resistance during gas delivery. A cylinder 22 is fixedly connected to the top of the push tube 20. The cylinder 22 serves as a power source. Through the reciprocating motion of the internal piston, the extension and retraction function of the push tube 20 is realized. Push rods 21 are fixedly connected to the left and right sides of the cylinder 22.
[0044] The push rod 21 is made of high-strength metal rod. One end is connected to the piston of the cylinder 22, and the other end is connected to a specific part of the push tube 20. Driven by the cylinder 22, the push tube 20 is pushed to extend and retract. The other end of the cylinder 22 is rotatably connected to the swing base 23. Output interfaces 24 are fixedly connected to the left and right sides of the swing base 23. The swing base 23 can swing freely within a certain angle range, so that the fire extinguishing device can cover a larger fire extinguishing range. Flame, vision, and infrared sensors 25 are fixedly connected to the left and right sides of the swing base 23. The flame, vision, and infrared sensors 25 adopt advanced infrared sensing technology, which can quickly and accurately detect flame signals in the surrounding environment and transmit the signals to the control system so as to activate the fire extinguishing device in time. The other end of the flame, vision, and infrared sensor 25 is fixedly connected to the telescopic tube 26. The telescopic tube 26 can adjust its length accordingly with the extension and retraction of the push tube 20 to ensure that the flame, vision, and infrared sensor 25 is always in the best detection position. The outside of the push tube 20 is fixedly connected to the top of the three-way solenoid valve 16.
[0045] The adjustment mechanism includes an adjustment frame 5, which is made of aluminum alloy and is lightweight and strong. The frame is rectangular and has a reasonable structural design, providing a stable installation base for the mounting bracket 6. The mounting bracket 6 is fixedly connected to the front of the adjustment frame 5. The mounting bracket 6 is made of thick metal plate and is shaped to fit the front of the adjustment frame 5. Inside the mounting bracket 6, a connecting shaft 7 is embedded and fixedly connected by high-precision machining. The connecting shaft 7 is made of high-quality stainless steel and is finely polished and heat-treated. It has a smooth surface and good toughness and wear resistance, ensuring that the rotating plate 8 can rotate smoothly and stably around it. The rotating plate 8 is rotatably connected to the outside of the connecting shaft 7. The rotating plate 8 is made of carbon steel and has a certain strength and rigidity to ensure that it will not easily deform during operation.
[0046] The rotating clamping plate 8 is externally fixedly connected to an elastic component, which includes a telescopic rod 9. The telescopic rod 9 consists of two layers of metal tubes, an inner tube that can freely extend and retract within the outer tube to achieve flexible length adjustment. A spring 10 is sleeved on the outside of the telescopic rod 9. The spring 10 is made of spring steel and undergoes a special heat treatment process, giving it good elasticity and fatigue life, and providing stable elastic force. The telescopic rod 9 is externally fixedly connected to the outside of the rotating clamping plate 8. The other end of the rotating clamping plate 8 is fixedly connected to a locking rod 11. The locking rod 11 is a slender metal rod with its end specially treated to form a sharp locking tooth shape, so as to precisely cooperate with the locking grooves 13 on other components to achieve position locking. The adjusting frame 5 is internally slidably connected to a connecting block 12. The connecting block 12 is made of wear-resistant engineering plastic material, and its shape matches the sliding groove inside the adjusting frame 5, allowing it to slide smoothly within the sliding groove while reducing friction during sliding. The adjusting frame 5 is externally fixedly connected to the left and right sides of the bracket 2.
[0047] Reference Figures 3 to 5 A nozzle 27 is fixedly connected to the front of the three-way solenoid valve 16. The nozzle 27 is made of a special alloy material, which has the characteristics of high temperature resistance and corrosion resistance. Its internal design has a unique spray hole structure, which can spray the gas in a specific spray shape and angle according to the type and pressure of the extinguishing gas, so that the extinguishing gas can cover the fire source more evenly and effectively, and improve the extinguishing efficiency. A pressure regulating valve and a filling valve 18 are fixedly connected to the left side of the three-way solenoid valve 16. The pressure regulating valve and the filling valve 18 adopt standard electrical connection specifications, which can be easily connected to an external power adapter or power supply system to provide a stable power supply for the electromagnetic control components of the three-way solenoid valve 16, ensuring that it can accurately execute the command of gas flow switching. A suction cup 14 is fixedly connected to the bottom of the connecting block 12. The suction cup 14 is made of a high elasticity and high adsorption rubber material. Its surface is designed with a special texture structure, which can enhance the friction and adsorption with the surface of the contact object.
[0048] The bottom left and right sides of the three-way solenoid valve 16 are fixedly connected to exhaust ports 17. The exhaust ports 17 are used to discharge excess gas or regulate pressure under specific circumstances to ensure that the internal air pressure of the device is always within a safe and stable range. The top of the three-way solenoid valve 16 is fixedly connected to a spare interface 19. The spare interface 19 can be used to connect additional gas push tubes 20, detection equipment or other auxiliary devices. The push rod 21, cylinder 22 and sway base 23 together form a multi-stage telescopic adjustment mechanism, which expands the coverage of the multi-functional telescopic automatic fire extinguishing device. The inside of the adjustment frame 5 is slidably connected to a connecting block 12. The outside of the connecting block 12 is provided with a slot 13. The outside of the locking rod 11 is engaged with the outside of the slot 13. The outside of the suction cup 14 is in contact with the outside of the adjustment frame 5 and the outside of the electric telescopic rod 3. One end of the spring 10 is fixedly connected to the outside of the rotating plate 8 and the other end of the spring 10 is fixedly connected to the outside of the adjustment frame 5.
[0049] The medium storage container 1 and the drive lifting mechanism are joined by mortise and tenon joints. The male tenon of the electric universal wheel plate base 4 is fixed to the medium storage container 1. The four corners of the male tenon of the electric universal wheel plate base 4 are provided with holes 28 for buckles. The female tenon of the electric universal wheel plate base 4 is connected to the electric universal wheel plate base 4 by an insert-type mortise and tenon structure, and is limited by spring 10. When the intelligent fire extinguishing device needs to be used in conjunction with the drive lifting electric universal wheel plate base 4, the electric universal wheel plate base 4 (female tenon) and the electric universal wheel plate base 4 are connected by an insert-type mortise and tenon structure. The mortise and tenon structure is used for connection, with spring 10 for buckle limit, so that the intelligent fire extinguishing device can be flexibly adjusted in height to expand the fire extinguishing range; when the intelligent fire extinguishing device needs to temporarily make use of the idle value of the electric universal wheel plate base 4 under the condition of ensuring safety, the male and female tenons are separated, and the holes 28 with buckles are opened around the four corners of the electric universal wheel plate base 4 (male tenon) and spliced to the base of the four electric telescopic rods 3 above the electric universal wheel plate base 4, so that the electric universal wheel plate base 4 can be transformed into a four-wheel drive tool vehicle in an instant, thereby improving the utilization value of the product;
[0050] The electric omnidirectional wheel base 4 has four holes 28 with latches on both sides. The latches are located at the lower openings of the base, allowing the electric omnidirectional wheel base 4 and the electric telescopic rod 3 to have three application options: latched onto the upper end of the electric telescopic rod 3, latched onto the lower end of the electric telescopic rod 3, or directly separated. When the intelligent fire extinguishing device is fixedly suspended and used, the suction cup 14 is connected to the electric telescopic rod 3, and the four-wheel drive electric omnidirectional wheel base 4 is separated. When the intelligent fire extinguishing device is used for ground-driven operation, the electric omnidirectional wheel base 4 is latched onto the lower end of the electric telescopic rod 3. When the intelligent fire extinguishing device is grounded and tracking a fire source, and the equipment needs to be raised to enhance stability and operational conditions, it is latched onto the upper end of the electric telescopic rod 3.
[0051] Working principle: When adjusting the position of the suction cup 14, pressing the rotating plate 8 causes it to press the telescopic rod 9. Under the action of the telescopic rod 9, the spring 10 outside the telescopic rod 9 deforms, which in turn causes the rotating plate 8 to drive the locking rod 11 to separate from the locking groove 13 outside the connecting block 12. Then, the suction cup 14 can be adjusted by pulling the locking groove 13. When the position is adjusted to a suitable position, the rotating plate 8 is released, causing the spring 10 to rebound, thus realizing the external adjustment of the suction cup 14.
[0052] When the flame, vision, and infrared sensors 25 detect a fire source signal, the signal is transmitted to the control system. Based on the received signal, the control system controls the electric telescopic rod 3 to extend and retract, moving the fire extinguishing device to the vicinity of the fire source. At the same time, the control system also controls the hollow electric rotary joint 15 to rotate, aligning the push tube 20 with the fire source. Then, the control system controls the three-way solenoid valve 16 to switch the gas output direction, allowing the fire extinguishing gas in the medium storage container 1 to be delivered to the nozzle 27 through the hollow electric rotary joint 15 and the push tube 20, and then sprayed out from the nozzle 27 to extinguish the fire source. During the fire extinguishing process, the push tube 20 can extend and retract according to the position of the fire source, which is accomplished by the cylinder 22 and the push rod 21.
[0053] Meanwhile, the swing-arm base 23 can also swing freely within a certain angle range, allowing the fire extinguishing device to cover a larger fire extinguishing area. During the fire extinguishing process, if it is necessary to change the position of the fire extinguishing device, it can be quickly moved to a new position by controlling the extension and retraction of the electric telescopic rod 3 and the steering of the electric universal wheel flat base 4. After the fire extinguishing process is completed, the control system will control the electric telescopic rod 3 to retract, returning the fire extinguishing device to its original position. At the same time, the control system will also control the three-way solenoid valve 16 to switch the gas output direction, stopping the output of fire extinguishing gas. Finally, the control system will control the exhaust port 17 to open, discharging excess gas from the medium storage container 1 to maintain the pressure inside the medium storage container 1 within a safe and stable range.
[0054] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
