Description

Technical Field

[0001] The present application relates to the technical field of emergency rescue equipment, and more specifically, to a liquid-carrying tank and a fire truck. Background Art

[0002] In order to ensure the safety of people's lives, firefighting is particularly important. With the development of society, the ability of firefighting units to deal with various accidents and firefighting and rescue work is getting stronger and stronger, and one of the important tools to ensure the effective implementation of firefighting and rescue work is the fire truck. One of the important indicators of the performance of a fire truck is the tank.

[0003] As introduced in patent CN102229349A, at present, the liquid tanks of emergency rescue fire trucks are mostly square tanks, and the side panels and bottom panels are connected by welding. The welding amount is large, the welding deformation is serious, and the contact position between the bottom panel and the side panel will appear wavy deformation, and the tank volume error is large. There is a right-angle transition at the welding point, which is easy to cause stress concentration. In severe cases, it will cause the weld to tear, and the welding quality requirements are high. When driving on bumpy roads for a long time or operating under extreme working conditions such as sudden braking, due to fatigue damage of the structure, cracks are easily generated at the welding defect position, causing water leakage and other faults. A few of the curved tank structures are overall elliptical tanks, which have low space utilization and more redundant load-bearing capacity. Models of the same volume often need to use a chassis with a larger load-bearing capacity, resulting in performance waste, and the remaining space on the top and sides is difficult to use.

[0037] The present application provides a liquid carrying tank and a fire truck, which are specifically as follows:

[0038] In a first aspect, an embodiment of the present application provides a liquid carrying tank, such as Figure 1 to Figure 6 As shown, Figure 1 This is a front view of a liquid carrying tank in an embodiment of the present application; Figure 2 This is a cross-sectional schematic diagram of a liquid-carrying tank in an embodiment of the present application; Figure 3 This is a left view of a liquid carrying tank in an embodiment of the present application; Figure 4 This is a right side view of a liquid carrying tank in an embodiment of the present application; Figure 5 A top view of a liquid-carrying tank in an embodiment of the present application; Figure 6 This is a bottom view of a liquid carrying tank in an embodiment of the present application. Figure 2 yes Figure 1 Cross-section along AA.

[0039] The liquid carrying tank comprises a shell having a hollow cavity, and the shell comprises a top plate 1, a bottom side plate 2, a front head 3 and a rear head 4.

[0040] Among them, the outline of the top plate 1 is rectangular, and the top plate 1 includes two opposite long sides and two opposite short sides; the bottom side plate 2 is integrally formed, and the bottom side plate 2 is connected to the two long sides, and the bottom side plate 2 includes two opposite arcuate surfaces, each of which is coplanar with one of the short sides; the front head 3 is connected to one of the short sides and one of the arcuate surfaces, and the rear head 4 is connected to the other short side and the other arcuate surface.

[0041] The embodiment of the present application is formed in one piece by the bottom side plate 2, which reduces the amount of welding compared to a square liquid-carrying tank, and the welding route is highly standardized, further ensuring the reliability of the load-bearing capacity. The top plate 1 is rectangular, and the bottom side plate 2 includes an arc-shaped surface, which can effectively disperse the stress and enhance the rigidity of the tank body compared to a tank body with a full arc-shaped cross-section. The increase in the effective cross-section can effectively exert the load-bearing capacity of the chassis, and the saved space can be used to set up an equipment box to place equipment. The expansion capability is strong, and the top plate 1 can reserve sufficient space for the installation and fixation of large equipment and special tools. When maintenance is required, the operator can stand on the top and is not easy to fall.

[0042] In some embodiments of the present application, the top plate 1 is a flat plate structure.

[0043] In some embodiments of the present application, there is an arc-shaped transition between the side surface and the bottom surface of the bottom side plate 2 .

[0044] In some embodiments of the present application, a transverse anti-sway plate 5 is also included, wherein the transverse anti-sway plate 5 is connected to the top plate 1 and the bottom side plate 2, a plurality of the transverse anti-sway plates 5 are arranged at intervals from each other, and the surface of the transverse anti-sway plate 5 has a hollow structure.

[0045] In some embodiments of the present application, a longitudinal anti-sway plate 6 is also included, and the longitudinal anti-sway plate 6 is connected to the transverse anti-sway plate 5, the front head 3 or the rear head 4. The longitudinal anti-sway plate 6 and the transverse anti-sway plate 5 are perpendicular to each other, and the surface of the longitudinal anti-sway plate 6 has a hollow structure.

[0046] The transverse anti-sway plate 5 and the longitudinal anti-sway plate 6 are composed of one or more flat and tough plates, and the shape and size of the plates can be customized according to the shape and size of the container. The edges of the plates are usually fixed to the container wall to prevent liquid from overflowing from the edges. The surface of the plate has a hollow structure for passing liquid.

[0047] The effect of the transverse anti-sway plate 5 and the longitudinal anti-sway plate 6 is to slow down and disperse the energy of the liquid in the container due to shaking or impact, thereby preventing the liquid from overflowing or splashing. It can also reduce the impact force suffered by the container wall and protect the container from damage.

[0048] The new type of liquid-carrying tank in this embodiment determines the shape and size of the tank body based on the tank body partition and head formed by oil pressure. The side panels and bottom panels are formed by curling a whole steel plate, and are welded while curling. The bottom and side surfaces are both arc transitions. The overall arc structure of the load-bearing part can effectively disperse stress and enhance the rigidity of the tank body. After welding, the accuracy of the outer dimensions is easier to control than that of a square tank. The top adopts a flat design, which can be consistent with the top plane of other modules of the fire truck to ensure the safety of personnel climbing to the top for maintenance. It can also be used to install and fix large equipment and special tools.

[0049] In some embodiments of the present application, a foam tube 7 is further included, the cavity includes a foam tank and a water tank arranged side by side, and the foam tank is connected to the water tank through the foam tube 7.

[0050] In some embodiments of the present application, it also includes an external foam injection pipe 8, an external water injection pipe 9, a rear water injection pipe 10 and a rear water inlet pipe 11. The foam tank is connected to the outside world through the external foam injection pipe 8, and the water tank is connected to the outside world through the external water injection pipe 9, the rear water injection pipe 10 and the rear water inlet pipe 11.

[0051] In some embodiments of the present application, a foam tank breathing valve 12 is further included, a through hole communicating with the foam tank is opened on the top plate 1, and the foam tube 7 breathing valve is covered on the through hole.

[0052] The working principle of the foam tank breathing valve 12: when the air pressure in the foam tank is too high, the valve core in the air chamber will rise, and then open the passage between the air chamber and the outside of the tank, so that the air in the tank can flow out; on the contrary, when the air pressure in the foam tank is low, the valve core in the air chamber will move down, close the passage with the outside of the tank, so that the air in the tank cannot flow out. In this way, the air pressure inside the foam tank can be effectively controlled, and the role of the foam tank in fire extinguishing can be better played under the premise of ensuring that the foam tank is not damaged. The air pressure inside the foam tank can be adjusted to ensure the balance of the air pressure inside and outside the tank, thereby avoiding damage and leakage of the tank body.

[0053] In some embodiments of the present application, a manhole 13 and an anti-vortex plate 14 are further included. A plurality of the manholes 13 are opened on the top plate 1 and are respectively connected to the water tank and the foam tank. The anti-vortex plate 14 is arranged on the inner side of the bottom side plate 2.

[0054] The manhole 13 is an important part of the fire truck, usually located on the top or side of the fire truck tank. Its structure is a metal round cover with an openable locking device in the center, which can facilitate personnel to enter the fire truck tank. The main function of the manhole 13 is to facilitate firefighters or other personnel to enter the fire truck for maintenance, inspection, replacement of equipment and other operations. At the same time, during firefighting operations, the manhole 13 can also be used for observation and ventilation.

[0055] The anti-vortex plate 14 is a device inside the tank of the fire truck, mainly located at the bottom of the fire water tank. Its structure is usually a flat plate, the periphery is fixed to the bottom of the tank, and the middle area can move. When the water pump of the fire truck is working, the water flows through the middle area of ​​the anti-vortex plate 14. Due to the effect of the anti-vortex plate 14, the water can flow evenly in all directions of the fire truck, avoiding the formation of vortices in the tank, thereby ensuring the smooth flow of the water.

[0056] The new type of liquid tank provided by the utility model has a mounting hole reserved on the base, and the tank body is connected to the modified subframe of the chassis through an elastic support seat. The liquid tank is designed based on work needs and chassis vehicle parameters, and the standardized and interchangeable fire truck chassis and subframe provide a good loading platform for the liquid tank. The optimized cross-sectional design is adopted, and the modification is made on the basis of the previous square liquid tank shape, avoiding the right-angle transition that is prone to stress concentration. The amount of welding is reduced. Compared with the square liquid tank, the amount of welding is reduced by about 30%. The welding route is highly standardized, and more efficient and high-quality robot welding and other methods can be used for processing, further ensuring the reliability of the load-bearing capacity.

[0057] The effective cross-section is large, and compared with the full-arc tank of the same size, the effective cross-section is increased by 27.35%, which can effectively exert the load-bearing capacity of the chassis, and the saved space can be used to set up equipment boxes to place equipment. The expansion capability is strong. Compared with the full-arc tank, the top of the tank of the utility model is a larger plane, which can reserve sufficient space for the installation and fixation of large equipment and special tools. When maintenance is required, the operator can stand on the top and is not easy to fall.

[0058] In a second aspect, an embodiment of the present application provides a fire truck, comprising a sub-frame, a tank base 15, an elastic support seat, and a liquid carrying tank as described in any one embodiment of the first aspect;

[0059] The tank base 15 is placed on the auxiliary frame, the liquid carrying tank is placed on the tank base 15, and the liquid carrying tank is connected to the auxiliary frame via the elastic support seat.

The top panel 1 is rectangular, and the bottom side panels 2 include curved surfaces, which can effectively disperse stress and enhance the rigidity of the tank body compared to a tank body with a full circular arc cross-section. The increase in the effective cross-section can effectively exert the load-bearing capacity of the chassis, and the saved space can be used to set up an equipment box to place equipment. The expansion capability is strong, and the top panel 1 can reserve sufficient space for the installation and fixation of large equipment and special tools. When maintenance is required, the operator can stand on the top and is not likely to fall.
