Description

Technical Field

[0001] This invention relates to the field of fire emergency technology, and in particular to a heating vehicle with emergency fire-fighting function. Background Technology

[0002] Existing emergency heating vehicles only have a single heating function. In municipal pipeline repair and disaster emergency scenarios, if a fire breaks out, a separate fire truck must be dispatched, resulting in low response efficiency and large space occupation by vehicles on site. Some vehicles that combine heating and firefighting functions simply stack functional components without clearly defining the installation location and layout relationship of each component. The pipeline routing is chaotic, making it impossible to draw standardized structural diagrams and causing problems such as inconvenient installation, difficult maintenance, and easy interference when switching modes.

[0003] When a fire breaks out at a work site, a dedicated fire truck must be dispatched separately. This presents challenges such as long emergency response times, large space requirements for multiple vehicles operating together, and limitations on passage and operations in narrow road sections. Existing vehicles that combine heating and firefighting functions are mostly simple superpositions of two systems, exhibiting drawbacks such as shared water lines leading to cross-contamination, lack of interlocking protection during mode switching, chaotic pipeline layout, redundant power systems, and poor operational stability. These vehicles cannot simultaneously meet the dual operational requirements of professional heating and reliable firefighting, and are ill-suited for complex and multifaceted emergency scenarios. Summary of the Invention

[0004] The purpose of this invention is to provide a heating vehicle with emergency fire-fighting function. By integrating heating and fire-fighting functions, it can achieve multiple uses in one vehicle, avoid interference from the mixing of media in the two systems, and improve the handling efficiency and operational safety in complex emergency scenarios.

[0020] Example 1 like Figures 1-2 As shown, the present invention provides a heating vehicle with emergency fire-fighting function, including a vehicle chassis 1, a heating assembly 2, a water storage tank 3, a delivery pipeline 4, a fire spraying mechanism 5, a pipeline switching valve group 6, and a linkage control mechanism 7; the vehicle chassis 1 includes a driver's cab 11 and a load-bearing frame 12, the driver's cab 11 is fixed to the front end of the load-bearing frame 12, and the heating assembly 2 is fixedly installed on the upper part of the load-bearing frame 12 and located behind the driver's cab 11.

[0021] The water storage tank 3 is fixedly installed on the upper part of the load-bearing frame 12 and located on the rear side of the heating assembly 2. The pipeline switching valve group 6 is fixedly installed on the upper part of the load-bearing frame 12 and located between the heating assembly 2 and the water storage tank 3. A part of the fire spraying mechanism 5 is installed on the top of the cab 11, and the other part of the fire spraying mechanism 5 is fixed on the outside of the water storage tank 3. The linkage control mechanism 7 is installed inside the cab 11.

[0022] The vehicle has a compact and orderly layout, with all functional components arranged longitudinally along the frame and the center of gravity evenly distributed to ensure vehicle stability. The partitioned arrangement of components facilitates installation, maintenance and operation. The control components inside the cab 11 are designed to meet human-machine operation habits and can be quickly operated in emergency situations.

[0023] The water storage tank 3 is connected in sequence to the pipeline switching valve group 6 and the heating assembly 2 via the delivery pipeline 4. The water storage tank 3 is also connected in sequence to the pipeline switching valve group 6 and the fire sprinkler mechanism 5 via the delivery pipeline 4. The delivery pipeline 4 is laid along the side of the load-bearing frame 12. This allows a single water source to supply water to both the heating and fire protection systems simultaneously, reducing the number of on-board tanks and saving frame space. The delivery pipeline 4 is neatly laid along the side of the load-bearing frame 12, avoiding pipeline crossing and entanglement, pressure damage, and facilitating pipeline layout and subsequent maintenance.

[0024] The pipeline switching valve assembly 6 is used to control the independent on / off connection of the water storage tank 3 and the heating assembly 2, as well as the connection between the water storage tank 3 and the fire sprinkler mechanism 5. This enables independent switching between the heating circuit and the fire circuit, ensuring that the two water circuits are not connected or interfere with each other, preventing the mixing and contamination of heating medium and fire water, preventing pressure impact between the two pipelines, and ensuring that both systems can operate stably and independently.

[0025] The linkage control mechanism 7 is electrically connected to the heating assembly 2, the fire sprinkler mechanism 5, and the pipeline switching valve group 6, respectively, and is used to switch between heating mode and fire emergency mode. Through centralized electrical control, the function mode can be switched with one button, the emergency response speed is fast, the operation is simple, and it is suitable for the rapid handling needs of sudden fires.

[0026] The heating assembly 2 includes a heating boiler 21, a heating circulation pump 22, and a heating output interface 23. The heating boiler 21 and the heating circulation pump 22 are fixed side-by-side on the load-bearing frame 12. The water inlet of the heating boiler 21 is connected to the pipeline switching valve group 6 via the delivery pipeline 4. The water outlet of the heating boiler 21 is connected to the water inlet of the heating circulation pump 22. The water outlet of the heating circulation pump 22 is connected to the heating output interface 23. The heating output interface 23 is fixed to the outer wall of the heating assembly 2 and is a quick-connect coupling. The structure is simple, with clear division of functions for heating, circulation, and output, and the side-by-side arrangement reduces the lateral space occupied. The quick-connect coupling heating output interface 23 can quickly connect to external heating pipelines, improving the efficiency of emergency heating connection.

[0027] The fire sprinkler system 5 includes a fire pump 51, a fire monitor 52, and a fire hose reel 53. The fire monitor 52 is fixedly installed at the top center of the cab 11. The fire pump 51 is fixed to the outer wall of the water storage tank 3. The fire hose reel 53 is fixed to the load-bearing frame 12 and located beside the water storage tank 3. The inlet of the fire pump 51 is connected to the pipeline switching valve group 6 through the delivery pipeline 4. The outlet of the fire pump 51 is connected to both the fire monitor 52 and the fire hose reel 53 through the delivery pipeline 4. The fire pump 51 is arranged close to the outside of the water storage tank 3 to shorten the water inlet path and reduce water intake resistance. The fire monitor 52, located on the roof, provides a wide field of vision and a wide spray coverage area. The fire hose reel 53 is convenient for close-range firefighting, and the combination of short-range and long-range firefighting capabilities enhances the applicability of firefighting.

[0028] The fire monitor 52 is horizontally rotatable and vertically tiltable, with its spray nozzle facing the front of the vehicle chassis 1. The water storage tank 3 is a horizontal tank with an internal insulation layer 31. The pipeline switching valve assembly 6 is an electric multi-way valve assembly, with its valve body fixed to the load-bearing frame 12. The fire monitor 52 has an adjustable angle, allowing for flexible aiming at the fire source and improving fire suppression accuracy. The water storage tank 3 is adapted to the vehicle frame layout and conforms to the overall vehicle structure. The insulation layer 31 reduces heat loss from the water, preventing freezing in low-temperature environments and maintaining the initial water temperature for heating. The pipeline switching valve assembly 6 is directly fixed to the load-bearing frame 12, ensuring a secure installation and preventing shaking or displacement during operation.

[0029] The linkage control mechanism 7 includes a control panel 71 and a sensor assembly 72. The control panel 71 is embedded in the center console of the driver's cab 11, and the sensor assembly 72 is fixed to the outer wall of the delivery pipeline 4 and close to the pipeline switching valve assembly 6. The control panel 71, embedded in the center console, is easy and intuitive to operate. The sensor assembly 72, located close to the pipeline switching valve assembly 6, can accurately monitor water pressure and water temperature signals. The monitored data is accurate and reliable, providing a precise basis for mode switching and safety protection.

[0030] The fire pump 51, heating circulation pump 22, and heating boiler 21 all share the onboard engine of the vehicle chassis 1 as their power source. This eliminates the need for an additional independent power unit, significantly simplifying the overall vehicle structure and reducing overall vehicle weight and manufacturing costs. Reducing the number of power components lowers the probability of failure, while simultaneously improving the utilization of onboard space and ensuring a stable power supply for heating and firefighting operations.

[0031] Working principle: The vehicle chassis 1 serves as the load-bearing and power base, and the water storage tank 3 serves as the unified water supply medium. The independent on / off control of the hot water supply circuit and the fire water circuit is achieved through the pipeline switching valve group 6. Under the centralized electrical control of the linkage control mechanism 7, the interlocking switching and stable operation of the two modes of emergency heating and emergency fire protection are completed. The power of the whole vehicle is uniformly provided by the vehicle engine. The two systems share the power and water source, and the structure is compact and does not interfere with each other.

[0032] The sensor assembly 72 collects water pressure and water temperature signals of the main delivery pipeline 4 near the pipeline switching valve group 6 in real time, and transmits the signals to the linkage control mechanism 7 in the cab 11. The control panel 71 is used by the operator to issue mode switching commands. The linkage control mechanism 7 controls the start, stop and on / off of the pipeline switching valve group 6, the heating assembly 2 and the fire spray mechanism 5 in a synchronous manner according to the commands and sensor signals, and at the same time realizes safety interlock protection.

[0033] In emergency heating mode, the operator switches to heating mode via control panel 71. The linkage control mechanism 7 controls the pipeline switching valve group 6 to open the water path from water storage tank 3 to heating boiler 21, while simultaneously cutting off the water path to fire pump 51. The vehicle-mounted engine drives heating boiler 21 and heating circulation pump 22. Water from water storage tank 3 enters heating boiler 21 via delivery pipeline 4 and is heated. The heated water is pressurized by heating circulation pump 22 and delivered externally through external heating output interface 23, achieving emergency heating operation. Sensor assembly 72 monitors pipeline pressure and water temperature in real time. The linkage control mechanism 7 automatically adjusts heating parameters based on the monitoring data to ensure stable heating conditions. At this time, fire pump 51 and fire monitor 52 remain in a standby state.

[0034] In emergency fire-fighting mode, when a fire occurs requiring extinguishing, the operator switches to fire-fighting mode via control panel 71. The linkage control mechanism 7 executes interlocking control, first stopping the operation of heating boiler 21 and heating circulation pump 22, then controlling pipeline switching valve group 6 to cut off the hot water supply circuit and open the fire-fighting water circuit. The vehicle-mounted engine drives fire pump 51, which draws water from storage tank 3 and pressurizes it. The high-pressure water is then delivered via pipeline 4 to fire monitor 52 and fire hose reel 53. The operator can adjust the horizontal rotation angle and vertical elevation angle of the fire monitor 52 on the vehicle roof for remote, high-flow fire extinguishing, or deploy the fire hose reel 53 for close-range, precise fire extinguishing. During this time, the heating circuit is shut down, preventing water from entering the heating assembly 2 and avoiding media mixing and equipment interference.

[0035] When the vehicle stops, the linkage control mechanism 7 controls the pipeline switching valve group 6 to reset to the fully closed state, cutting off the water outlet passage of the water storage tank 3. The sensor component 72 continuously monitors the pipeline pressure to prevent pipeline pressure buildup and damage. The insulation layer 31 inside the water storage tank 3 can maintain the water temperature and prevent low-temperature freezing, ensuring that the vehicle can be put into normal use in different environments.

[0036] Therefore, the present invention adopts a heating vehicle with emergency fire-fighting function as described above. The dual water circuits can be switched independently without interference, and the shared power and water source simplify the structure. The mode can be switched with one button for rapid response. It can effectively extinguish fires both near and far. The tank body is insulated to prevent freezing. The sensors monitor and protect the equipment in real time. It has both efficient heating and reliable fire-fighting capabilities.

[0037] The above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
