Description

Technical Field

[0001] This application relates to the technical field of fire trucks, and in particular to a multi-functional miniaturized fire truck. Background Art

[0002] With the acceleration of the urbanization process, residential communities are showing a trend of high-density development. According to the "Code for Fire Protection Design of Buildings" (GB50016-2014), the net width of the fire truck passage in the community should be ≥4m and the net height should be ≥4m. However, in actual management, the effective passage width is often reduced to less than 2.5m due to the parking of private cars and the occupation of temporary structures. According to the statistical data of the Emergency Management Department in 2022, 32.7% of the high-rise residential building fires nationwide had delays in rescue caused by blocked fire truck passages, revealing a significant adaptation contradiction between traditional fire fighting equipment and the urban microenvironment.

[0003] To meet the fire extinguishing efficiency requirements specified in GB7956.1-2014 "Fire Trucks - Part 1: General Technical Conditions", current mainstream fire trucks generally adopt a configuration of a large-capacity water tank (≥3000L) and a multi-stage centrifugal pump set, resulting in a vehicle length exceeding 8m and a minimum turning radius ≥10m. For a typical model such as the Dongfeng Tianjin foam fire truck (dimensions 9.8×2.5×3.5m), its passability and maneuverability are severely limited during operation in narrow lanes. It often needs to adopt secondary transfer or manual connection methods to implement rescue, resulting in a loss rate of the golden rescue time reaching more than 40%. Therefore, there is an urgent need for a multi-functional miniaturized fire truck to meet fire fighting needs. Summary of the Invention

[0004] To solve the above technical problems, this application provides a multi-functional miniaturized fire truck, which has the advantages of reducing the overall size of the fire truck while ensuring the diversity of fire fighting functions to meet fire fighting needs.

[0005] To achieve the above object, the technical solution of the present invention is as follows:

[0006] A multi-functional miniaturized fire truck includes a vehicle body, a carriage is arranged on the vehicle body, a water tank is arranged near the front of the carriage, a pull-out carrier is arranged at the tail of the carriage, a diesel water pump is detachably arranged on the pull-out carrier, storage racks are arranged on both sides of the pull-out carrier, and a number of fire fighting tools are arranged on the storage racks;

[0007] The water tank is arranged in a T shape, and a number of water pipe joints are arranged at the bottoms of both sides of the water tank.

[0008] Implement the above technical solution, that is, the wheels are independently driven by four wheels to ensure the flexibility and passability of vehicle steering. And because the vehicle body is electrically driven, there is no need to set up a gearbox and other space-consuming components compared with the transmission engine type vehicle body. Therefore, the vehicle body size is smaller, and the compartment space can be increased while ensuring the overall space of the vehicle remains unchanged. At the same time, a battery compartment is provided at the bottom of the chassis, and the power battery can be detachably arranged in the battery compartment so that the entire vehicle can ensure the driving force by replacing the power battery, thereby ensuring applicability. Because the volume of the compartment increases, the volume of the water tank can be ensured, and the diesel water pump is installed at the rear of the compartment through a pull-out carrier. Therefore, when in use, the diesel water pump can be pulled out of the compartment through the pull-out carrier, and then connected to the water pipe joint at the bottom of the water tank through a fire hose, so as to achieve the effect of water supply and fire extinguishing. And because the diesel water pump is movably installed in the box body through a pull-out carrier, there is no need to consider the requirement of the operation space for water pipe connection. Therefore, the operation space at this place can be used to install other devices, thereby ensuring the diversity of functions to meet the fire situation requirements.

[0009] As a preferred solution of the present application, the pull-out carrier includes a support frame, a pair of heavy-duty locking slide rails are arranged on the support frame, a carrier plate is arranged between the two heavy-duty locking slide rails, and a locking member is arranged between the carrier plate and the diesel water pump.

[0010] As a preferred solution of the present application, a pull-out handle is arranged at the end of the carrier plate.

[0016] As a preferred embodiment of the present application, the fixing member includes a hanging rod provided at the bottom of the rolling shutter door, and a retaining hook that is downwardly bent is provided on the vehicle body.

[0017] The above technical solution is realized as follows: by tightening the hanging rod and hanging it on the retaining hook, under the elastic action of the self-closing rolling shutter door, it abuts upward against the retaining hook, thereby completing the fixing effect to achieve the effect of quick locking.

[0018] As a preferred embodiment of the present application, an installation frame is provided at the top of the carriage. The installation frame includes an installation frame and a fixing bracket provided in the installation frame, and a warning light is provided on the outer side wall of the installation frame.

[0019] The above technical solution is realized as follows: corresponding special equipment required for a fire can be installed on the fixing bracket for the use of firefighters, and the warning light is arranged around the outer side wall of the installation frame without affecting the installation of the equipment.

[0020] As a preferred embodiment of the present application, a folding ladder is provided at the tail of the box body.

[0021] The above technical solution is realized to facilitate the installation of personnel.

[0022] As a preferred embodiment of the present application, the vehicle body includes a chassis, and wheels with four-wheel independent drive are provided on the chassis, as well as a power battery for driving the wheels to rotate.

[0023] The above technical solution is realized as follows: the wheels are four-wheel independently driven, which ensures the flexibility and passability of vehicle steering. And because the vehicle body is electrically driven, there is no need to set a gearbox and other components that occupy space compared with a vehicle body with a transmission engine. Therefore, it is ensured that the vehicle body is small in size. When the overall space of the vehicle remains unchanged, the space of the carriage can be increased.

[0024] As a preferred embodiment of the present application, a battery compartment is provided at the bottom of the chassis, and the power battery is detachably arranged in the battery compartment.

[0025] The above technical solution is realized so that the entire vehicle can ensure the driving force by replacing the power battery, thereby ensuring the applicability.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. That is, the wheels are independently driven in four-wheel mode to ensure the flexibility and passability of vehicle steering. And because the vehicle body is electrically driven, there is no need to set up a gearbox and other space-consuming components compared with the vehicle body with a transmission engine, thus ensuring a smaller vehicle body size.

Detailed implementation manners

[0035] The following further elaborates on this application Figures 1-5 in conjunction with the appended drawings.

[0036] An embodiment of this application discloses a multi-functional miniaturized fire truck. Referring to Figures 1-2 , the multi-functional miniaturized fire truck includes a vehicle body 1, and a carriage 11 is arranged on the vehicle body 1. The vehicle body 1 includes a chassis 12, and four-wheel independent drive wheels 13 are arranged on the chassis 12, as well as a power battery 14 that drives the wheels 13 to rotate. That is, the wheels 13 are four-wheel independently driven to ensure the flexibility and passability of vehicle steering, and because the vehicle body 1 is electrically driven, there is no need to set up a gearbox and other components that occupy space compared with a vehicle body 1 with a transmission engine. Therefore, the size of the vehicle body 1 is small, and when the overall space of the vehicle remains unchanged, the space of the carriage 11 can be increased. At the same time, a battery compartment is arranged at the bottom of the chassis 12, and the power battery 14 of the power battery is detachably arranged in the battery compartment, so that the entire vehicle can ensure driving force by replacing the power battery 14, thereby ensuring applicability.

[0037] A water tank 2 is arranged near the front of the carriage 11.

At the same time, after the carrier plate 33 is sent into the box body, the locking hook 323 can be hooked in the positioning groove 324 to ensure that the diesel water pump 9 does not shake during driving. The locking member can be directly locked by screws and nuts, or fixed by quick clamps such as vises, which is convenient for personnel to disassemble.

[0039] Self-closing rolling doors 6 are provided on both sides of the carriage 11. A fixing member for fixing the rolling door is provided between the bottom of the self-closing rolling door 6 and the vehicle body 1. So that after the personnel unlock the fixing member, the self-closing rolling door 6 quickly shrinks upward and quickly opens under the action of the coil spring inside itself, thereby improving the unlocking efficiency and being convenient for firefighters to use. The fixing member includes a hanging rod 61 arranged at the bottom of the rolling door. A retaining hook 62 that bends downward is provided on the vehicle body 1. That is, by tightening the hanging rod 61 and hanging it on the retaining hook 62, it abuts upward against the retaining hook 62 under the elastic action of the self-closing rolling door 6, thus completing the fixing effect to achieve the effect of quick locking.

In order to facilitate personnel installation, a folding ladder 8 is provided at the tail of the box body.

[0041] The implementation principle of a multifunctional miniaturized fire truck in an embodiment of the present application is as follows: The wheels 13 are independently driven by four wheels to ensure the flexibility and passability of vehicle steering. Moreover, since the vehicle body 1 is electrically driven, there is no need to set up a gearbox and other space-consuming components compared with the transmission engine type vehicle body 1. Therefore, the size of the vehicle body 1 is small. When the overall space of the vehicle remains unchanged, the space of the carriage 11 can be increased. At the same time, a battery compartment is provided at the bottom of the chassis 12, and the power battery 14 can be detachably arranged in the battery compartment so that the entire vehicle can ensure the driving force by replacing the power battery 14, thereby ensuring applicability. Because the volume of the carriage 11 increases, the volume of the water tank 2 can be ensured. The diesel water pump 9 is installed at the tail of the carriage 11 through the pull-out carrier 3. When in use, the diesel water pump 9 can be pulled out of the carriage 11 through the pull-out carrier 3, and then connected to the water pipe joint 21 at the bottom of the water tank 2 through a fire hose, so as to achieve the effect of water supply and fire extinguishing. And because the diesel water pump 9 is movably installed in the box body through the pull-out carrier 3, there is no need to consider the requirement of the operation space for water pipe connection. Therefore, the operation space here can be used to install other devices, thereby ensuring the diversity of functions to meet the fire situation requirements.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
