Description

Technical Field

[0001] This utility model belongs to the technical field of electric fire trucks, and in particular relates to a box-type electric water supply fire truck with high passability. Background Technology

[0002] With the development of urbanization, housing and urban roads are becoming increasingly congested. During fire and rescue missions, large fire trucks have difficulty passing through congested sections of road or narrow alleys, which greatly limits their mobility and makes them unsuitable for fire and rescue missions in urban alleys or narrow roads. Summary of the Invention

[0003] Purpose of the invention: In order to overcome the shortcomings of the existing technology, this utility model provides a highly maneuverable box-type electric water supply fire truck. By designing the fire truck into a small box, its flexibility and mobility are improved, enabling it to pass smoothly through congested and narrow urban areas and quickly reach the fire scene, thus meeting the needs of urban fire rescue missions.

[0004] Technical solution: To achieve the above objectives, this utility model provides a high-passability box-type electric water supply fire truck, which includes a main frame and a truck body. The main frame serves as a walking platform to support the truck body, and an electric water supply system is installed inside the truck body.

[0005] The electric water supply system includes a water tank, an electric water pump, and nozzles connected in sequence via fire water pipes; the vehicle body is equipped with a telescopic frame with a universal control panel; the electric water pump is positioned to enter and exit the vehicle body via the extension and retraction of the telescopic frame; the nozzles are mounted on the universal control panel to adjust the direction of water spray.

[0006] Furthermore, side plates are provided on both sides of the main frame, and an on-board power battery is installed on the main frame through the side protection of the two side plates. The electric water supply system is powered by the on-board power battery.

[0007] Furthermore, a water supply control valve is connected between the outlet of the water tank and the inlet of the fire water pipe.

[0008] Furthermore, both sides of the vehicle body are provided with doors, and the telescopic frame extends in a direction perpendicular to the doors.

[0009] Furthermore, the telescopic frame includes a guide rail and a movable frame that slides and fits on the guide rail. The electric water pump and the universal control panel are both mounted on the movable frame, and the telescopic frame has a positioning pin.

[0010] Furthermore, the universal control panel includes a vertical shaft, a base that is pivotally coupled to the lower end of the vertical shaft, and an operating handle that is hinged to the upper end of the vertical shaft. The base is fixedly mounted on the movable frame, and the nozzle is mounted on the operating handle.

[0011] Furthermore, the shaft rotation fit between the vertical shaft and the base is a damped shaft rotation fit, and the hinge fit between the operating handle and the upper end of the vertical shaft is a damped hinge fit.

[0012] Furthermore, the nozzle is a fire hose head with a built-in manual valve.

[0013] Beneficial effects: This utility model improves the flexibility and mobility of fire trucks through the miniaturization and electrification of the box-type design. It can smoothly pass through congested and narrow urban areas and quickly reach the fire scene, ensuring that the small fire truck can play a key role in urban alleyway firefighting missions and meet the needs of urban fire rescue missions. It makes up for the shortcomings of large fuel fire trucks, which are limited by factors such as mobility, traffic and buildings and cannot quickly reach the fire scene. At the same time, the small box-type electric fire truck is equipped with an electric water supply system, which is combined with an electric water pump that can extend outside the box and nozzles that can flexibly adjust the direction of water spray, improving the flexibility of fire fighting.

[0015] Figure 2 This is a structural diagram of the electric water supply system, telescopic frame, and universal control panel of the box-type electric fire truck. Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] like Figure 1 and Figure 2 As shown, a high-accessibility box-type electric water supply fire truck includes a main frame 1 and a truck body 2. The main frame 1 serves as a walking platform to support the truck body 2. An electric water supply system 3 is installed inside the truck body 2. The electric water supply system 3 includes a water tank 5, an electric water pump 6, and nozzles 15 connected in sequence via fire water pipes 4. A telescopic frame 7 with a universal control panel 8 is installed inside the truck body 2. The electric water pump 6 is positioned to enter and exit the truck body 2 by extending and retracting the telescopic frame 7. The nozzles 15 are mounted on the universal control panel 8 to adjust the direction of water spray. This utility model improves the flexibility and mobility of fire trucks by miniaturizing and electrifying them, enabling them to pass smoothly through congested and narrow urban areas and quickly reach the fire scene. This ensures that small fire trucks can play a key role in urban alleyway firefighting missions and meet the needs of urban fire rescue missions. It also makes up for the shortcomings of large fuel-powered fire trucks, which are limited by factors such as mobility, traffic, and buildings, making it difficult for them to reach the fire scene quickly. At the same time, the small box-type electric fire truck is equipped with an electric water supply system 3, which is combined with an electric water pump 6 that can extend outside the box and nozzles 15 that can flexibly adjust the direction of water spray, thus improving the flexibility of fire fighting.

[0018] More specifically, the main frame 1 is provided with side plates 9 on both sides, and the vehicle power battery 10 is provided on the main frame 1 through the side protection of the two side plates 9. The electric water supply system 3 is powered by the vehicle power battery 10.

[0019] In order to control the water discharge in the water tank 5, a water supply control valve 11 is connected between the water outlet of the water tank 5 and the water inlet of the fire water pipe 4. The water supply control valve 11 can be an electric valve or a purely mechanical valve.

[0020] It is worth noting that both sides of the vehicle body 2 are provided with doors 12, and the telescopic frame 7 is perpendicular to the doors 12 in the telescopic direction. The electric water pump 6 and nozzles 15 can extend from both sides of the vehicle body 2, which makes it more adaptable and flexible for water spraying and fire extinguishing.

[0021] like Figure 1 As shown, the telescopic frame 7 includes a guide rail and a movable frame 72 that slides on the guide rail 71. The electric water pump 6 and the universal control panel 8 are both mounted on the movable frame 72, and the telescopic frame 7 has a positioning pin 73. The universal control panel 8 includes a vertical shaft 81, a base 82 that is pivotally mounted on the lower end of the vertical shaft 81, and an operating handle 83 that is hingedly mounted on the upper end of the vertical shaft 81. The base 82 is fixedly mounted on the movable frame 72, and the nozzle 15 is mounted on the operating handle 83. To improve the convenience of operating the nozzle 15 and increase stability when not in use, the pivotal fit between the vertical shaft 81 and the base 82 is a damped pivotal fit, and the hinged fit between the operating handle 83 and the upper end of the vertical shaft 81 is a damped hinged fit.

[0022] In this utility model, preferably, the nozzle 15 is a fire hose head with a built-in manual valve.

[0023] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
