The protective cabin filled with liquid slides to buffer the impact of the liquid during the acceleration or braking process of the vehicle. The liquid forms a whole when stored in the cabin. As the vehicle moves, the shaking amplitude is large. The synchronous shaking of all the liquid makes the impact force on the cabin body huge. Only using spring buffering will also form aftershocks. There is room for optimization in the buffering method during the liquid transportation process.

[0018] Beneficial effects

[0019] The present utility model provides a liquid discharger for petroleum fracturing. It has the following beneficial effects:

[0020] 1. The liquid drainer for oil fracturing, through multiple partitions, among which the convection trough with the largest size needs to face the front of the vehicle, and the partition with the smallest convection trough faces the rear of the vehicle. When the vehicle accelerates, the liquid in the storage body gradually flows from the largest convection trough towards each partition. Since the sizes of the multiple convection troughs decrease, the liquid can impact each partition when flowing through the multiple convection troughs, so that the momentum of the liquid is converted, thereby realizing the deceleration of the liquid. The multiple partitions can also divide the storage body cavity, so that the liquid stored in the storage body is stored in multiple chambers. During acceleration, it can also reduce the impact caused by the overall sloshing of the liquid. When the vehicle decelerates and brakes, the liquid flows from the smallest convection trough towards the largest convection trough. Due to the partition of the multiple partitions, the liquid will enter the interval between the two partitions and form a turbulent flow when flowing through each convection trough, suppressing the overall sloshing of the liquid and the impact on the vehicle, making the flow velocity of the liquid between adjacent two partitions different, thereby suppressing the interference of the overall liquid flow on the vehicle and ensuring the stability and safety of driving.

[0021] 2. The liquid drainer for oil fracturing, when the vehicle accelerates and the liquid flows towards the smaller convection trough, the liquid passes through and impacts the next partition in the horn-shaped channel formed by the two turning bodies, realizing the deceleration of the liquid. And the liquid will also flow back to form an impact. When the liquid flows back, the liquid will impact the turning bodies and the partition. The smaller port of the horn-shaped channel formed by the two turning bodies faces the flowing-back liquid, and the liquid needs to enter from the smaller port, with relatively greater resistance, having the dual effects of shunting and decelerating the liquid;

[0022] Secondly, when the liquid passes between the two turning bodies, it will also impact the turning bodies. The turning bodies rotate around the connecting rod, and then the extension rod abuts against the partition and is compressed and deformed, converting and consuming the impulse of the flowing liquid, realizing the deceleration of the liquid. When the liquid is stable, the extension rod resets under its own elastic potential energy, and the turning bodies are pushed by the extension rod to fit against the limit blocks and form a horn-shaped channel with another turning body, having the effect of automatically adjusting the position and resetting, and having a better effect on consuming the kinetic energy of the liquid.

[0029] A liquid drainer for oil fracturing, as Figure 1 and Figure 2 shown, includes:

[0030] A storage body 10, which is a box structure for storing the flowback fluid. A pipe for draining the fluid is fixedly installed on one side of the storage body 10. A filter is installed on the top surface of the storage body 10. The flowback fluid enters the chamber of the storage body 10 from the filter. The filter includes a filter box and filter plates laid in the filter box. A liquid inlet pipe is fixedly installed at the top of the filter box. The flowback fluid after filtration treatment is stored in the storage body 10 and can be discharged from the drain pipe for recycling after being transported by a vehicle. Details are not elaborated here;

[0031] As Figure 2 , Figure 3 and Figure 4As shown, the spacer component is arranged in the cavity of the storage body 10 to partition the cavity of the storage body 10. The spacer component includes a partition 11, a convection groove 12, and a communication groove 13. A number of partitions 11 are fixedly connected to the inner wall of the storage body 10. A communication groove 13 of the same size is opened at the bottom of each partition 11. The chambers on both sides of the partition 11 are connected through the communication groove 13. A convection groove 12 with different sizes is opened at the middle position of each partition 11. When the return liquid sloshes in the cavity of the storage body 10, it can impact each partition 11 and be decelerated; the storage body 10 forms a rectangular box structure. The partition 11 is a rectangular plate, and the partition 11 is adapted to the cavity of the storage body 10. The convection groove 12 is a rectangular groove, which is opened at the bottom of the partition 11 and extends towards the center position of the partition 11. The convection groove 12 is a directional notch. The sizes of the convection grooves 12 opened on the walls of multiple partitions 11 decrease uniformly along the liquid flow direction. Specifically, through multiple partitions 11, the convection groove 12 with the largest size needs to face the vehicle head direction, and the partition 11 with the smallest convection groove 12 faces the vehicle tail direction. When the vehicle accelerates, the liquid in the storage body 10 gradually flows from the largest convection groove 12 towards each partition 11. Due to the decreasing sizes of the multiple convection grooves 12, when the liquid flows through the multiple convection grooves 12, it can impact each partition 11, so that the momentum of the liquid is converted, thereby realizing the deceleration of the liquid. Multiple partitions 11 can also partition the cavity of the storage body 10, so that the liquid stored in the storage body 10 is stored in multiple chambers. During acceleration, it can also reduce the impact caused by the overall sloshing of the liquid. When the vehicle decelerates and brakes, the liquid flows from the smallest convection groove 12 towards the largest convection groove 12. Due to the partitioning of multiple partitions 11, when the liquid flows through each convection groove 12, it will enter the space between two partitions 11 and form a turbulent flow, suppressing the overall sloshing of the liquid and the impact on the vehicle, and ensuring the stability and safety of driving.

[0032] As Figure 3 and Figure 5As shown in the figure, the spoiler assembly is arranged on one side of the partition 11 for decelerating and diverting the flowing backflow liquid. The spoiler assembly includes a connecting rod 20, a flipping body 21, an extension rod 22, and a limiting block 23. Two connecting rods 20 are fixedly connected to the same side of the partition 11. The same limiting block 23 is fixedly arranged at the bottom of each connecting rod 20. A flipping body 21 is rotatably connected to the bottom of each connecting rod 20. The two flipping bodies 21 together form a trumpet-shaped channel. A extension rod 22 is fixedly arranged on each flipping body 21. The extension rod 22 can abut against the partition 11 and be deformed by the extrusion of the flipping body 21. The flipping body 21 forms a rectangular plate structure. The two flipping bodies 21 on the same side of the partition 11 are distributed in an outward V shape. The two flipping bodies 21 are located on both sides of the convection groove 12. The limiting block 23 is integrally formed with the connecting rod 20. The limiting block 23 is trapezoidal. The inclined surface of the limiting block 23 is attached to the flipping body 21. The extension rod 22 is integrally formed with the flipping body 21. The extension rod 22 includes a rectangular rod body and an arc rod body. The arc rod body is fixedly connected to the rectangular rod body. The end of the rectangular rod body is fixedly connected to the flipping body 21. The arc rod body abuts against the partition 11. As a supplementary description of the above solution, by arranging a plurality of flipping bodies 21, the flipping bodies 21 extend obliquely in the direction of liquid flow. When the vehicle accelerates and the liquid flows towards the smaller convection groove 12, the liquid passes through the trumpet-shaped channel formed by the two flipping bodies 21 and impacts the next partition 11, achieving deceleration of the liquid. And the liquid will also flow back to form an impact. When the liquid flows back, the liquid will impact the flipping body 21 and the partition 11. The smaller port of the trumpet-shaped channel formed by the two flipping bodies 21 faces the backflow liquid. The liquid needs to enter from the smaller port, and the resistance is relatively large, having the dual effects of diverting and decelerating the liquid.

[0033] Secondly, when the liquid passes between the two flipping bodies 21, it will also impact the flipping body 21. The flipping body 21 rotates around the connecting rod 20. Then the extension rod 22 abuts against the partition 11 and is compressed and deformed, converting and consuming the impulse of the flowing liquid, achieving deceleration of the liquid. When the liquid is stable, the extension rod 22 resets under its own elastic potential energy. The flipping body 21 is pushed by the extension rod 22 to fit against the limiting block 23 and form a trumpet-shaped channel with the other flipping body 21, having the effect of automatically adjusting the position and resetting, and having a better effect on consuming the kinetic energy of the liquid.

[0034] Working principle of the utility model: The convection chute 12 with the largest size needs to face the front of the vehicle, and the partition 11 with the smallest convection chute 12 faces the rear of the vehicle. When the vehicle accelerates, the liquid in the storage body 10 gradually flows from the largest convection chute 12 towards each partition 11. Due to the decreasing size of the multiple convection chutes 12, the liquid can impact each partition 11 when flowing through the multiple convection chutes 12, so that the momentum of the liquid is converted, thereby realizing the deceleration of the liquid. The multiple partitions 11 can also divide the chamber of the storage body 10, so that the liquid stored in the storage body 10 is stored in multiple chambers, and when accelerating, the impact caused by the overall sloshing of the liquid can also be reduced. When the vehicle decelerates and brakes, the liquid flows from the smallest convection chute 12 towards the largest convection chute 12. Due to the partition of the multiple partitions 11, the liquid will enter the interval between the two partitions 11 and form a turbulent flow when flowing through each convection chute 12. When the vehicle accelerates and the liquid flows towards the smaller convection chute 12, the liquid passes through the horn-shaped channel formed by the two turning bodies 21 and impacts the next partition 11 to realize the deceleration of the liquid, and the liquid will also flow back to form an impact. When the liquid flows back, the liquid will impact the turning body 21 and the partition 11. The smaller port of the horn-shaped channel formed by the two turning bodies 21 faces the flowing-back liquid, and the liquid needs to enter from the smaller port, and the resistance is relatively large. When the liquid passes between the two turning bodies 21, it will also impact the turning body 21. The turning body 21 rotates around the connecting rod 20, and then the extension rod 22 abuts against the partition 11 and is compressed and deformed, converting and consuming the impulse of the flowing liquid to realize the deceleration of the liquid. When the liquid is stable, the extension rod 22 resets under its own elastic potential energy, and the turning body 21 is pushed by the extension rod 22 to fit against the limit block 23 and form a horn-shaped channel with the other turning body 21.
