Detailed Description
The present application will now be described in further detail with reference to the drawings, it should be noted that the following detailed description is given for illustrative purposes only and is not to be construed as limiting the scope of the present application, as those skilled in the art will be able to make numerous insubstantial modifications and adaptations to the present application based on the above disclosure.
An improved tank truck transport tank contains an improved tank truck breakwater structure:
as shown in fig. 1 to 4, an improved breakwater structure of a tank truck comprises a breakwater and a guide plate, wherein the breakwater and the guide plate are both fixedly connected with the inner wall of a tank body, the breakwater comprises three groups of transverse breakwater perpendicular to the axis of the tank body and two groups of longitudinal horizontal breakwater parallel to the axis of the tank body, the two groups of guide plates are respectively positioned at two sides of the longitudinal horizontal breakwater, five groups of transverse breakwater are arranged in the tank body of a conventional transportation tank, the whole tank has a large weight, and after the longitudinal horizontal breakwater is added, the two groups of transverse breakwater can be reduced, so that the weight of the transportation tank is reduced.
As shown in fig. 3, the longitudinal horizontal breakwater is located at the upper part of the inner cavity of the tank body, the longitudinal horizontal breakwater is inclined to the horizontal direction, the height H of the longitudinal horizontal breakwater from the bottom end of the transport tank body is 0.6D-0.9D, D is the inner diameter of the transport tank body, the horizontal inclination angle α is 2-5 °, the longitudinal horizontal breakwater is a rectangular steel plate, the length of the longitudinal horizontal breakwater is the same as the length of the tank body, and the width L is the same as the length of the tank body1Is between 0.6D and 0.7D, and has a thickness L23 mm-6 mm, a plurality of groups of circular diversion holes are arranged on the longitudinal horizontal wave-proof plate and are distributed on the longitudinal horizontal wave-proof plate in an even lattice manner, and the diameter D of each diversion hole1The distance L between the diversion holes is 0.005D-0.015D along the width direction of the longitudinal horizontal wave-proof plate30.2D-0.3D, and the interval distance L is arranged between the diversion holes along the longitudinal direction of the longitudinal horizontal wave-proof plate4Is 0.2D to 0.5D.
As shown in fig. 4, the baffle is in the shape of a circular arc with a radius R10.05D-0.15D, a circular arc central angle beta of 30-60 degrees, a length identical to that of the longitudinal horizontal breakwater and a thickness L53 mm-6 mm, both ends and one side end of the guide plate are welded on the end caps at both ends of the transport tank body, the other side end of the guide plate extends to the lower part of the longitudinal horizontal breakwater, and the overlapping length L of the other side end of the guide plate and the longitudinal horizontal breakwater60.005D-0.015D, the other side end of the guide plate and the longitudinal directionSpacing L between horizontal breakwaters7Is 0.002D to 0.005D.
The invention has simple structure, and the longitudinal horizontal wave guard plate and the two flow deflectors are added in the tank body, so that the kinetic energy generated by the liquid shaking of the tank truck in the transportation process can be effectively absorbed by the wave guard plate, more importantly, due to the existence of the longitudinal horizontal wave guard plate, the billowing caused by the residual kinetic energy of the liquid when impacting the transverse wave guard plate is also greatly limited, for example, when the liquid level in the tank body of the liquid tank truck is lower than the longitudinal horizontal wave-proof plate, most kinetic energy of the liquid is absorbed by the transverse wave-proof plate during braking, and the small part of the liquid is blocked by the longitudinal horizontal wave-proof plate and the flow guide plates on the two sides, so that the minimum part of the liquid enters the upper half part of the tank body through the flow guide holes on the longitudinal horizontal wave-proof plate, however, as the longitudinal horizontal breakwater is inclined at a certain angle, the liquid flows back to the bottom along the guide plates on the two sides under the action of gravity; when the liquid level in the tank body of the liquid tank truck is higher than the longitudinal horizontal wave-proof plate, the longitudinal horizontal wave-proof plate divides the liquid in the tank body into an upper part and a lower part, the transverse wave-proof plate, the longitudinal horizontal wave-proof plate and the guide plates on the two sides can effectively reduce the mutual influence among the liquids of the parts, the liquid of the lower part is sealed by the wave-proof plate, and the liquid of the upper part occupies a smaller proportion, so the impact generated by the liquid of the upper part is smaller. Therefore, the scheme can prevent the tank body from generating larger liquid surge, and can better realize the wave-proof function.
Examples
Three groups of common transverse breakwaters with the same structure are arranged in the tank body, the structure of each transverse breakwater is shown in figure 5, round holes are arranged on the transverse breakwaters, the diameter of each round hole is 450mm, when the inner diameter D of the tank body is 2300mm, the height H of the longitudinal horizontal breakwater from the bottom end of the conveying tank body is 0.84D, the horizontal inclination angle alpha is 5 degrees, and the width L of the longitudinal horizontal breakwater1Is 0.65D, and has a thickness L2Is 5mm, and the diameter D of the diversion hole1The distance L between the diversion holes is 0.005D-0.015D along the width direction of the longitudinal horizontal wave-proof plate30.2D-0.3D, and the interval distance L is arranged between the diversion holes along the longitudinal direction of the longitudinal horizontal wave-proof plate40.2D-0.5D, and the radius of the circular arc R1Is 0.08D, the central angle beta of the circular arc is 50 degrees, and the thickness L5Is 5mm, and has an overlap length L6Is 0.01D, the interval L7Was 0.003D.
Comparative example

The comparative example and the example are subjected to simulation experiments, the stress of the comparative example (original breakwater) and the example (optimized breakwater) is changed along with time as shown in fig. 7, and it can be seen from the graph that compared with the comparative example, the peak value of the load borne by the breakwater of the example is obviously reduced, the average stress is also smaller, and the peak value of the impact force along the time caused by the water hammer effect is also greatly reduced; the liquid simulation of the example (optimized breakwater) and the comparative example (original breakwater) is embodied by the liquid three-dimensional sloshing cloud over time, as shown in fig. 8 and 9, and it can be seen that the sloshing of the liquid is also limited due to the existence of the horizontal breakwater and the stability thereof is enhanced in the example relative to the comparative example.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
