[0002] A forest forward fire truck is a special vehicle specifically used for emergency rescue of forest fires. It usually has high maneuverability and off-road capabilities, can quickly reach the scene of the fire, and perform information collection and initial disposal tasks. This type of fire truck is usually equipped with communication equipment, detection equipment and fire-fighting equipment to effectively respond to forest fires in complex terrain and environments.

[0003] In order to ensure the maneuverability and off-road performance of forest front-end fire trucks, existing forest front-end fire trucks (such as publication number CN218923645U) generally adopt an off-road chassis, and the driver's cab, body, water cannon, etc. are installed on the off-road chassis. The body has its own water tank and foam liquid tank and is equipped with a pressurized water supply structure, which can arrive at the fire scene as soon as possible and perform early fire extinguishing tasks.

[0004] However, the existing forest front-end fire fighting trucks only consider maneuverability and off-road performance, but do not consider safety performance during forest front-end fire fighting. Specifically, the forest environment and terrain are complex, and the traditional forest front-end fire fighting truck has a traditional car body structure. When the fire truck rolls over, the car body (especially the driver's cabin) is very likely to be deformed and damaged, causing injury to the driver, and the water cannon at the front of the vehicle is generally connected to the water supply structure through a water pipe, and the water pipe is inevitably in an exposed state. The water pipe is very likely to be caught or scratched by branches, shrubs, etc. during front-end fire fighting, resulting in failure of the fire extinguishing function. Utility Model Content

[0026] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme of the utility model will be clearly and completely described below in combination with the drawings in the specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the utility model, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0027] In a typical implementation of the present invention, Figure 1-Figure 3 As shown, a forest front-end fire truck is proposed, including: a body, a drive system 12, a steering system 10, an electrical system, a braking system, a fire extinguishing system and a front-end disposal system. The drive system 12, the steering system 10, the electrical system, the braking system, the fire extinguishing system and the front-end disposal system are all integrated in the body, so that the whole vehicle has an integrated structure, eliminating the subframe and strengthening the body structure.

[0028] The vehicle body includes a frame 1, a suspension, a driving compartment, an equipment box 4 and seats. The frame 1 is a cage structure welded with high-strength profiles, which can enhance the strength and torsion resistance of the vehicle body and can be used as a roll cage to effectively offset the impact of the ground, prevent deformation of the frame 1 and protect the driver and passengers.

[0029] In this embodiment, the wheelbase of the vehicle is 2700mm and the overall dimensions are 4000×2000×2000mm. The approach angle and departure angle of the forward fire truck are much larger than 25°, which is more suitable for mountain and forest fire fighting. It has strong off-road performance, and has functions such as forward warning, battlefield segmentation, long-range search, high-pressure water mist, and dry powder combination, and can be adapted to different fire fighting needs.

[0030] The suspension is fixed between the frame 1 and the wheels. The driver's cabin is the space enclosed by the frame 1. The driver's cabin is isolated from the equipment box 1. The seats and the steering system 10 are arranged in the driver's cabin. The driver's cabin is an open structure (specifically, there is no door), which saves the time of opening the door. The actions of getting on and off the vehicle can be completed quickly, and it is more suitable for emergency work scenarios such as forest front-line firefighting.

[0031] The equipment box 4 is an all-aluminum frame structure, and the interior of the equipment box 4 is modularly divided into boxes to facilitate space management. The equipment box 4 is fixedly installed at the rear of the frame 1, and a box door 5 is slidingly provided on one side of the equipment box 4. The box door 5 is opened by sliding and folding up and down. Specifically, the box door 5 includes two door panels arranged up and down, wherein the top of the upper door panel is hinged to the top of the equipment box 4, and the bottom is hinged to the top of the lower door panel located below, and the bottom of the lower door panel is slidably connected to the equipment box 4, so that the box door 5 can be quickly opened by pulling the lower door panel upwards. The opening speed is fast, which is suitable for tense fire-fighting scenes.

[0032] It is understandable that the door 5 can be opened manually or electrically, and the specific opening method is not restricted too much here.

[0033] The driving system 12 is an existing four-wheel drive system, which is composed of an electric wheel, a motor and a reducer; the steering system 10 is composed of a steering gear, a steering rod system, a column tube, etc.; the electrical system is arranged in the equipment box 4, and the electrical system is composed of a distribution box, a controller, a charger, a battery, etc.; the braking system is composed of a brake pump, a brake disc, a brake line, etc.

[0034] It should be noted that the drive system 12, the steering system 10, the electrical system and the braking system are all existing structures, and the specific structures and settings will not be described in detail here.

[0035] The fire extinguishing system includes a hand-lift pump, a water tank, a water cannon 11 and a dry powder fire extinguisher, wherein the hand-lift pump, the water tank and the dry powder fire extinguisher are all placed in the equipment box 4, the water cannon 11 is fixedly installed at the front of the vehicle (i.e., in front of the driver's cab), and a high-pressure pump group 8 is also provided in the equipment box 4. The profile of the frame 1 is a hollow structure. The water cannon 11 is connected to the water tank through the frame 1 and the high-pressure pump group 8, so that the water in the water tank can be pumped into the profile of the frame 1, and transported to the water cannon 11 through the frame 1, and sprayed outward by the water cannon 11. The water cannon 11 is an electrically controlled lifting structure, which can be vertically lifted and lowered by more than 800 mm, and can be used to spray water, powder and other fire extinguishing media.

[0036] By conveying water through the frame 1, the use of water pipes is eliminated, and the problem of water pipe leakage is avoided. In forest front-line firefighting work, the damage to the water pipes caused by scratches and pulling by branches, shrubs, etc. is effectively avoided, and the adaptability of forest firefighting is improved. At the same time, its maneuverability and off-road performance are improved, and it can be applied to more complex field environments.

[0037] A water hose rack 7 is also provided in the equipment box 4. The water hose rack 7 is connected to the water tank through a high-pressure pump group 8. A water hose can be used for fire extinguishing. The high-pressure pump group 8 can realize vehicle-mounted water mist fire extinguishing, and can also be used as a relay station for pressurization operations to meet the needs of high-altitude operations.

[0038] The forward emergency handling system consists of a warning box 3, a warning light 2, and a remote exploration light 6, wherein the warning box 3 is fixedly mounted on the top of the cab by welding and is made of pressed aluminum film. Warning equipment such as warning cones and warning tapes are placed in the warning box 3 for first-time handling of the fire scene; the warning light 2 is fixedly mounted on the top of the warning box 3, and the warning light 2 is connected to the electrical system in the equipment box 4 for warning work; the remote exploration light 6 is fixedly mounted on the top of the equipment box 4 and is also connected to the electrical system for remote lighting exploration work. The remote exploration light 6 is bidirectionally installed along the length direction of the vehicle body, and can be used for remote alternating search at night. The small lifting lighting can be expanded to expand the search field of view.

[0039] A nitrogen cylinder group 9 is fixedly provided at the rear of the vehicle. The nitrogen cylinder group 9 is installed through a foldable retractable structure and can be stored when not in use. It can be connected to the inside of the frame 1 to be used to pressurize micro dry powder into the frame 1 and then spray the dry powder through a water cannon 11.

[0040] Since the cab is an open structure, in order to avoid flames from harming the driver and passengers, a number of sprinkler heads are fixed on the frame 1. The sprinkler heads are evenly fixed on the sides of the top of the cab and arranged in a fan shape. The sprinkler heads are connected to the interior of the frame 1, and are connected to the water tank in the equipment box 4 through the frame 1 and the high-pressure pump group 8, thereby forming a high-pressure water curtain on the sides of the cab to facilitate passing through the fire area and avoid flames from harming the driver and passengers.

[0041] It should be noted that there is no sprinkler head on the front windshield to avoid high-pressure water mist blocking the driver's view.

[0042] The specific working principle is:

[0043] Drive the emergency fire truck to the scene and conduct fire investigation on the scene to understand the specific location, size and direction of the fire;

[0044] Formulate fire fighting plans based on fire investigation results;

[0045] When the fire fighting work is carried out according to the fire fighting plan, the fire area is first isolated and guarded by using the warning equipment, and then the corresponding fire fighting method (such as water mist fire fighting, dry powder fire fighting or water-powder mixed fire fighting) is selected according to the fire fighting plan, and the water cannon 11 is used to fight the fire in the designated area;

[0046] Among them, when high-pressure fine water mist is used to extinguish the fire, the high-pressure pump group 8 is used to press water into the frame 1, and the fire is extinguished by adjusting the height and pitch of the water cannon 11; when dry powder is used to extinguish the fire, the nitrogen bottle group 9 is opened, the dry powder is pressed into the frame 1 and transported to the water cannon 11, and then sprayed by the water cannon 11; when water and powder are mixed to extinguish the fire, the high-pressure pump group 8 and the nitrogen bottle group 9 are used in combination to mix water and powder in the frame 1 and transport them to the water cannon 11.

[0047] When an emergency occurs at the fire scene (such as the increase in fire intensity, emergency rescue, etc.), the driver turns on the sprinkler head on the side of the frame 1 to form high-pressure water mist around the driver's compartment, isolating the interior of the driver's compartment from the external flames, making it easier for the vehicle to pass through the fire area.

[0048] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
