Description

Technical Field

[0001] This utility model belongs to the technical field of electric washing vehicles, and in particular relates to an electric washing vehicle with a vehicle-mounted water tank. Background Technology

[0002] The water tanks of existing electric washing trucks generally use fixed longitudinal baffles to suppress swaying. This structure has limited effect on suppressing swaying when the water level is half full (30%-60%). The increase in the free surface of the water body leads to an increase in the amplitude and force of lateral swaying, and the center of gravity shifts. This greatly increases the risk of the vehicle tilting and overturning when turning. At the same time, the repeated impact of water flow on the baffles can easily cause fatigue cracking of the welds. Summary of the Invention

[0003] Purpose of the invention: In order to overcome the shortcomings of the existing technology, this utility model provides a vehicle-mounted water tank electric washing vehicle. Through the combination of the built-in buoyancy of the water tank and the counterweight, the structural design of adaptive lifting and lowering to track the water surface is realized, which solves the problems of swaying and loss of control when the tank is half full and the easy damage of the fixed partition structure, thereby improving the safety of the electric washing vehicle.

[0004] Technical solution: To achieve the above objectives, this utility model provides a vehicle-mounted water tank electric washing vehicle, which includes a frame, wheels at the bottom of the frame, a driver's seat and a cargo box at the front and rear of the frame, and a water tank inside the cargo box.

[0005] The water tank is equipped with a fixed longitudinal partition and a liftable horizontal anti-surge plate. The longitudinal partition is provided with a vertical guide groove, and the horizontal anti-surge plate is provided with a slider, which is slidably connected in the guide groove.

[0006] The flat wave deflector is fixedly sealed to the top of a buoyancy chamber and has a counterweight suspended at the bottom. The difference between the buoyancy of the buoyancy chamber and the gravity of the counterweight drives the flat wave deflector to track the water level in real time.

[0007] Furthermore, the counterweight is a detachable modular structure, which includes counterweight blocks of two or more mass specifications.

[0008] Furthermore, the buoyancy cavity is filled with closed-cell foam material or is an inflatable sealed cavity.

[0009] Furthermore, a silicone oil damper is connected to the bottom of the flat wave deflector, and the counterweight is installed on the silicone oil damper.

[0010] Furthermore, the buoyancy cavity is divided into multiple independent sealed chambers, which are distributed in a matrix along the surface of the wave deflector.

[0011] Furthermore, the guide groove opening is provided with a limit block to block the slider and prevent the flat anti-wave plate from detaching from the longitudinal partition.

[0012] Furthermore, the surface of the flat baffle plate is provided with guide holes, and the inner wall of the guide holes is covered with an elastic rubber ring.

[0013] Furthermore, a flow port is provided at the bottom of the longitudinal partition, and the adjacent compartments formed by the separation of the water tank by the longitudinal partition are connected through the flow port.

[0014] Furthermore, the rear of the vehicle body is provided with a door, and the top is provided with a water inlet corresponding to the opening of the water tank, and the water tank is fixedly connected to the water tank bracket inside the vehicle body.

[0015] Furthermore, the driver's seat is equipped with a driver's platform, a windshield, and a roof, and also includes a seat compartment corresponding to the driver's platform and accommodating the power battery.

[0016] Beneficial effects: This utility model uses the difference between the buoyancy of the buoyancy chamber and the gravity of the counterweight to drive the horizontal anti-surge plate to track the water level in real time. It can actively adapt to water surface fluctuations, keeping the horizontal anti-surge plate in a suitable position at all times. This effectively suppresses water sloshing in the water tank, stabilizes the vehicle's center of gravity, reduces instability caused by water sloshing during vehicle operation, and improves vehicle driving stability. In particular, it solves the problems of uncontrolled sloshing under half-tank water conditions and easy damage to the fixed baffle structure, thus improving the safety of electric washing truck operation.

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] like Figure 1 As shown, a vehicle-mounted water tank electric washing vehicle includes a frame 1, with wheels 2 mounted on the bottom of the frame 1. A driver's seat 4 and a cargo box 5 are respectively located at the front and rear of the frame 3. The cargo box 5 houses a water tank 6. The cargo box 5 has a door 9 at the rear and a water inlet 10 at the top corresponding to the opening of the water tank 6. The water tank 6 is fixedly connected to a water tank bracket 11 inside the cargo box 5. The driver's seat 4 includes a driver's platform 41, a windshield 42, and a roof 43, and also includes a seat compartment 44 corresponding to the driver's platform and housing a power battery.

[0022] like Figure 2As shown, the water tank 6 is equipped with a fixed longitudinal partition 7 and a liftable horizontal anti-surge plate 8. The longitudinal partition 7 is provided with a vertical guide groove 70, and the horizontal anti-surge plate 8 is provided with a slider 80, which is slidably connected to the guide groove 70. The top of the horizontal anti-surge plate 8 is fixedly connected to a sealed buoyancy cavity 81, and the bottom is suspended by a counterweight 82. By the difference between the buoyancy of the buoyancy cavity 81 and the gravity of the counterweight 82, the horizontal anti-surge plate 8 is driven to track the water level in real time, which can actively adapt to water surface fluctuations and keep the horizontal anti-surge plate 8 in a suitable position. This effectively suppresses water sloshing in the water tank 6, stabilizes the vehicle's center of gravity, reduces instability caused by water sloshing during vehicle operation, and improves vehicle driving stability. In particular, it solves the problems of uncontrolled sloshing under half-tank water conditions and easy damage to the fixed partition structure, thus improving the safety of electric washing truck operation.

[0023] In existing technologies, the longitudinal baffle 7 is used to suppress water sloshing in the direction of travel, but often neglects to suppress water sloshing in the vertical direction. The wave deflector 8 of this invention not only suppresses water sloshing in the vertical direction, but also automatically tracks changes in water level to ensure the continuity and stability of the sloshing suppression effect. It should be noted that the longitudinal baffle 7 is similar to the baffles commonly found in existing technologies. However, in this invention, the longitudinal baffle 7 also guides the lifting and lowering movement of the horizontal wave deflector 8. This eliminates the need for other guiding mechanisms, simplifying the structure and reducing costs. The addition of the horizontal wave deflector 8, together with the longitudinal baffle 7, achieves a better sloshing suppression effect while reducing the impact force of water on the longitudinal baffle 7.

[0024] like Figure 2 and Figure 3 As shown, in order to quickly adjust the counterweight ratio according to the water load, such as when the load is empty and the weight needs to be reduced, and to optimize the lifting response, the counterweight 82 is a detachable modular structure, which includes counterweight blocks of two or more mass specifications, to improve the adaptability under different working conditions and improve the stability of the electric washing vehicle under different load conditions.

[0025] More specifically, the buoyancy cavity 81 is filled with closed-cell foam material or is an inflatable sealed cavity. Closed-cell foam material provides stable buoyancy, is lightweight, corrosion-resistant, and not easily damaged by water absorption, ensuring the long-term effective operation of the buoyancy cavity 81; the inflatable sealed cavity allows for adjustment of the inflation volume to change the buoyancy magnitude as needed, facilitating rapid adjustment of the buoyancy cavity buoyancy under different working conditions, enabling the horizontal wave deflector 8 to better adapt to changes in the water surface, and improving the flexibility and reliability of the sway suppression measures.

[0026] Since vehicle start-stop can easily cause the wave deflector to vibrate violently, in order to resist inertial interference, a silicone oil damper 21 is connected to the bottom of the flat wave deflector 8. The counterweight 82 is installed on the silicone oil damper 21. When braking or accelerating suddenly, the silicone oil damper 21 absorbs kinetic energy, reduces the fluctuation amplitude of the flat wave deflector 8, makes the flat wave deflector 8 move more smoothly, and further improves the sway suppression effect.

[0027] The silicone oil damper 21 is installed vertically, with its cylinder fixed to the bottom of the horizontally placed baffle 8 and its piston rod extending downwards and connecting to the counterweight 82. When the vehicle brakes suddenly, the horizontally placed baffle 8 moves downwards due to inertia, and the silicone oil damper 21 is axially compressed, consuming kinetic energy through the viscous resistance of the silicone oil; when accelerating, the horizontally placed baffle 8 floats upwards, and the silicone oil damper 21 is axially stretched to generate directional damping force.

[0028] The buoyancy chamber 81 is divided into multiple independent sealed compartments 8.1, which are distributed in a matrix along the surface of the wave deflector 8. Firstly, the multi-compartment design disperses risk; when some compartments are damaged, others can still provide buoyancy, ensuring the basic function of the horizontal wave deflector 8. Secondly, the matrix-distributed sealed compartments 8.1 generate buoyancy more evenly, making the force on the horizontal wave deflector 8 more balanced, enhancing its stability, and facilitating better tracking of water level and suppression of water sloshing. Thirdly, in existing technologies, when a vehicle is traveling, the centrifugal force of curves can easily cause unilateral buoyancy failure. With the matrix-type independent sealed compartments, local buoyancy units work independently, maintaining overall balance even with slight horizontal tilt or a small tilt angle, thus achieving the purpose of resisting tilt failure.

[0029] The guide groove 70 is provided with a limit block 71 at its opening to block the slider 80 and prevent the horizontal anti-surge plate 8 from detaching from the longitudinal partition 7. The mechanical hard limit block 80 is used to prevent the slider 80 from disengaging and avoid structural damage under extreme working conditions.

[0030] The surface of the flat-mounted wave deflector 8 is provided with guide holes 83, and the inner wall of the guide holes 83 is covered with an elastic rubber ring 84. The guide holes 83 allow some water flow to pass through, that is, allow water to flow appropriately on both sides of the wave deflector. This not only avoids excessive water pressure difference caused by the wave deflector blocking the flow, but also disperses large-scale eddies, decomposing the lateral impact water flow into multiple small-flow water flows, reducing the instantaneous impact force on the flat-mounted wave deflector 8. Furthermore, when the vehicle accelerates or brakes rapidly, the water level difference between the front and rear compartments increases, and the guide holes 83 form a passive pressure relief channel, accelerating water level balance and preventing the flat-mounted wave deflector 8 from deforming due to pressure on one side. The elastic rubber ring 84 can prevent the flat-mounted wave deflector 8 from resonating due to water flow hitting the wall of the guide holes 83. At the same time, under low-speed conditions, the elastic rubber ring 84 is in a natural state, and the guide holes 83 are fully open to ensure water flow. Under high-speed impact, the water flow compresses the inner wall of the elastic rubber ring 84, deforming the hole diameter dynamically, thereby automatically enhancing the flow suppression effect.

[0031] The bottom end of the longitudinal partition 7 is provided with a flow port 72. The adjacent compartments 60 formed by the longitudinal partition 7 of the water tank 6 are connected through the flow port 72, so that the pressure difference between the adjacent compartments 60 is eliminated in a short time and the water level is balanced.

[0032] 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.
