Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0018] Example. A rescue trailer with basic fire-fighting capabilities, comprising as follows: Figure 1-3As shown, the vehicle includes a front end 1 and a body 2. The upper rear side of the body 2 is provided with a mounting base 3, and a boom winch mechanism is provided on the mounting base 3. The rear of the body 2 is provided with a lifting and traction mechanism. The vehicle is characterized in that a counterweight 4 is provided on the upper front side of the body 2, and a water tank 5 with a shape matching the counterweight 4 is provided outside the counterweight 4. An anti-sway mechanism is provided inside the water tank 5. Welding rods 12 are evenly distributed on the surface of the counterweight 4. A docking seat 13 corresponding to the welding rods 12 is provided on the outside of the water tank 5. A tool cabinet 6 is provided on the side of the mounting base 3, and a fire-fighting component is provided in the tool cabinet 6.

[0019] The water tank 5 includes a main body 10 located behind the counterweight 4, and a mating part 11 located on the upper front side of the main body 10.

[0020] The anti-sway mechanism includes a first anti-sway mechanism located within the main body 10 and a second anti-sway mechanism located within the mating part 11. The first anti-sway mechanism includes multiple sets of vertically arranged first partitions 14. The second anti-sway mechanism includes multiple sets of vertically arranged second partitions 16, with staggered openings at the bottom of each partition 16, and evenly distributed second through holes 17 within each partition 16. The anti-sway mechanism reduces the impact of liquid in the water tank 5 on the vehicle body during the operation of the rescue trailer.

[0021] The fire-fighting assembly includes a fire pump 7 for controlling the liquid spraying out of the water tank 5, a fire hose 8 on one side of the fire pump 7, and a nozzle 9 at the end of the fire hose 8.

[0022] The docking seat 13 includes a rigid support 18, which includes a vertical plate 19. A first horizontal plate 20 is located on the upper side of one end of the vertical plate 19, and a second horizontal plate 21 is located on the lower side of the other end. The inner sides of the first horizontal plate 21 and the vertical plate 19 are provided with retaining strips 22 corresponding to the welding rod 12. A rubber pad 23 is provided on one side of the retaining strip 22. The docking seat 13 improves the stability of the connection between the water tank 5 and the counterweight 4.

[0023] The principle of this utility model: This application is a further improvement on the existing rescue trailer. A counterweight 4 is installed at the head of the vehicle body 2 to improve the stability of the vehicle load. A water tank 5 is installed on one side of the counterweight 4 to provide extinguishing agent for fire rescue. The water tank 5 includes a main body 10 and a mating part 11, which enhances the connection with the counterweight 4 and makes full use of space. Specifically, the main body 10 can be 1190 cm long, 750 cm wide, and 1350 cm high. The mating part is 1190 cm long, 1050 cm wide, and 500 cm high. A docking seat 13 is provided on one side of the water tank 5, which can connect with the welding rod on the surface of the counterweight 4 to achieve stable installation of the water tank 5. A rubber pad 23 is provided on one side of the mounting clip 22 to absorb some of the impact when the water tank shakes. The water tank 5 is used in conjunction with the fire-fighting components in the tool cabinet 6. The fire pump is connected to the water tank 5, and the fire hose 8 is connected through the fire pump 7 to achieve water spraying. Fire pump 7 is a small electric fire pump (3-5 kW), whose power can be matched according to the water tank capacity and fire spray distance requirements. Alternatively, a 3 kW fire pump 7 can be selected. If a DN50 (nominal outer diameter 56mm) fire hose is used for fire hose 8, a 20-meter length of hose can generally be considered in practical applications. With a 3 kW power output, the water flow velocity in the hose can reach approximately 1.5-2 m / s when the fire pump is working normally. This flow velocity ensures stable water delivery in the pipeline and creates an effective spray effect at the nozzles. Head: Based on the relationship between power and head and the pump's characteristic curve, the head of a 3 kW fire pump is approximately 25-30 meters. Head here refers to the fire pump's ability to lift water from the water tank to a certain height and ensure sufficient pressure for spraying. In practical applications, considering factors such as pipe resistance and nozzle pressure loss, a head of 25-30 meters ensures that water can still be sprayed at a certain pressure with a 20-meter water pipe length, achieving an effective spray distance of approximately 15-18 meters, which is sufficient for initial fire suppression within a certain range. If a 5 kW fire pump is selected, and a DN50 fire hose is also used, the water pipe length can be appropriately increased to 25-30 meters. This is because with increased power, the fire pump has stronger power to overcome the resistance of the longer pipe, ensuring normal water delivery and spraying. Water velocity: With a power increase of 5 kW, the water velocity in the pipe can reach approximately 2-2.5 m / s. Higher velocity allows the water to have greater kinetic energy during spraying, thereby increasing the spray distance and intensity. Head: A 5 kW fire pump can generally achieve a head of 35-40 meters. Even with a 30-meter water pipe length, considering various pressure losses, the water can still be sprayed with sufficient pressure, achieving an effective spray distance of 18-20 meters. This allows for better initial fire suppression for some initial fires that require a longer spray distance.During use, it was discovered that the sloshing of the liquid in water tank 5 affected the stability of the vehicle, mainly due to the large free surface area of ​​the liquid and the significant impact of the sloshing. Therefore, this application incorporates an anti-sloshing mechanism inside the water tank to reduce the impact of the water flow. This is achieved by dividing the water tank into smaller spaces using a first partition 14 and a second partition 16, reducing the free space of the water and thus reducing the impact of the water sloshing. The first partition 14 is vertically positioned along the front-rear direction of the vehicle body 2 to prevent significant impact when the vehicle turns. The second partition 14 is vertically positioned along the width of the vehicle body 2, which reduces the impact of the water flow during vehicle deceleration. Furthermore, an elastic sheet is installed on the second partition 16 to further reduce the impact of the water flow; alternatively, a foam board cushioning pad can be used. This application not only improves rescue efficiency—with the addition of a simple fire-fighting function—but also allows the rescue tow truck to quickly extinguish fires in their early stages, reducing property damage and casualties, indirectly creating significant economic benefits, and lowering rescue costs. By promptly extinguishing initial fires, large-scale rescue operations caused by the fire's expansion can be avoided, further reducing rescue costs.
