Description

Technical Field

[0001] The invention relates to the technical field of liquid tank trucks, and more particularly to a liquid storage tank of a liquid tank truck with a wave-proof function. Background Art

[0002] Liquid tank trucks are special vehicles mainly used to transport various liquid goods, such as oil products, chemical liquids, food, etc. They are usually composed of a second-class automobile chassis, a special tank body, a chemical pump and other components. The tank body has various shapes, including round, oval, square, etc., to meet the transportation needs of different liquids. Liquid tank trucks have various designs and functions, and their tank bodies are generally equipped with accessories such as wave-breaking plates, manholes, and liquid outlet valves.

[0003] Among them, the wave-breaking plate is installed on the inner side of the liquid storage tank of the liquid tank truck. By contacting with the liquid, it can reduce the swaying amplitude of the liquid inside the liquid tank truck during driving and improve the safety of the liquid tank truck. In the prior art, such as the application number CN202322869330.1, a wave-breaking structure for a liquid tank truck and a liquid tank truck are disclosed. It includes: a ring plate assembly, a guide device, a pad and a baffle; the ring plate assembly is arranged to fit the inner wall of the liquid tank truck along the circumferential direction, and openings are formed at both ends of the ring plate assembly at the bottom of the liquid tank truck; the guide device is arranged at the opening, and the guide device is fixedly connected to both ends of the ring plate assembly; the pad is arranged between the end of the ring plate assembly and the liquid tank truck; a number of baffles are arranged in sequence and spaced apart, and the two ends of the baffle are connected to the side of the ring plate assembly.

[0004] In the above device, although it solves the problem of insufficient connection strength between the wave-breaking plate and the tank truck, there are still certain deficiencies. For example, the baffle is vertically fixed to the reinforcing ring plate by bolts. Although one side of the baffle is set to be convex outward to enhance the impact resistance to the liquid and its own rigidity, the liquid in the liquid storage tank body flows in the opposite direction when the tank truck is driving and emergency braking. When the flow direction of the liquid is opposite to the protruding side of the baffle, the baffle's resistance to the liquid will be weakened. In addition, the back of the baffle is impacted by the liquid for a long time, and under the action of internal stress, it is prone to fatigue and breakage. Summary of the invention

DETAILED DESCRIPTION

[0038] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0039] Please refer to Figure 1 A liquid tank truck liquid storage tank with wave-proof function includes: a liquid storage tank body 1, four wave-proof mechanisms 2 are evenly distributed in the liquid storage tank body 1, the number of wave-proof mechanisms 2 is not limited to four, and can be adjusted according to actual use requirements, which is mainly used to evenly divide the internal space of the liquid storage tank body 1 into a plurality of small spaces to reduce the amplitude of liquid shaking.

[0040] Please refer to Figure 2 and Figure 3The wave-proof mechanism 2 includes a mounting portion 21, a sensing portion 22, a driving portion 23 and three wave-proof contact portions 25; wherein the mounting portion 21 is adapted to the inner side of the liquid storage tank body 1, and is fixed to the inner side of the liquid storage tank body 1. The three wave-proof contact portions 25 are evenly distributed linearly up and down on one side of the mounting portion 21, and their ends are rotatably connected to the mounting portion 21, and the wave-proof contact portion 25 is parallel to the liquid surface in the liquid storage tank body 1, and the wave-proof contact portion 25 in the middle is located in the middle position of the annular body 211, and the wave-proof contact portion 25 includes an impact contact surface, and the angle between the impact contact surface and the liquid surface in the liquid storage tank body 1 is an obtuse angle. Compared with the existing right-angle form, the present invention is set to an obtuse angle, which can reduce the height of the liquid being stirred up when the liquid hits the wave-proof contact portion 25, so as to reduce the degree of shaking of the liquid. The wave-proof contact portion 25 is used to It contacts the shaking liquid in the liquid storage tank body 1 to reduce the shaking amplitude of the liquid; the sensing part 22 is signal-connected with the driving part 23, which is used to sense the flow direction of the liquid in the liquid storage tank body 1 in real time, and send the sensing result to the driving part 23; the driving part 23 is connected with three wave-proof contact parts 25, and the driving part 23 drives the locking part 24 to move to the unlocked state according to the received liquid flow direction sensing result, and after releasing the locking effect on the rotating end of the wave-proof contact part 25, it continues to drive several wave-proof contact parts 25 to flip synchronously, so that the impact contact surface faces the liquid flow direction.

[0041] For details, please refer to Figures 3 to 6 The driving part 23 is arranged in the mounting part 21. The driving part 23 includes a controller, a driving source 231, a main driving part and three secondary driving parts. The controller is connected to the driving source 231 by signal. The driving source 231 can be a servo motor. The driving end of the driving source 231 is connected to the main driving part. The number of the secondary driving parts is the same as that of the wave-proof contact parts 25. One end of the three secondary driving parts is connected to the main driving part, and the other end thereof is connected to the three wave-proof contact parts 25 accordingly. The driving source 231 drives the main driving part to move, so that the secondary driving part synchronously drives the corresponding wave-proof contact part 25 to perform a flipping action with its rotating end. The main driving member includes a driving gear 232 and an arc-shaped rack 233. The driving gear 232 is fixed to the driving end of the driving source 231. An arc groove 234 adapted to the arc-shaped rack 233 is provided in the mounting portion 21. The arc-shaped rack 233 is slidably installed in the arc groove 234. The outer arc surface and the inner arc surface of the arc-shaped rack 233 are both provided with tooth segments. The driving gear 232 is meshed with the outer arc surface tooth segment of the arc-shaped rack 233; the secondary driving member includes a driven gear 235 and two bevel gears 236. The driven gear 235 is rotatably connected to the inner side wall of the arc groove 234, and one side thereof is meshed with the inner arc surface tooth segment of the arc-shaped rack 233. The two bevel gears 236 are respectively fixed to the driven gear 235 and the rotating end of the wave-proof contact portion 25, and the two bevel gears 236 are meshed.

[0042] It should be noted that when the driving part 23 is in use, the sensing part 22 detects the flow direction of the liquid inside the liquid storage tank body 1. When the flow direction of the liquid changes, the sensing part 22 sends the detection result to the controller. After receiving the detection result, the controller converts it into a control signal to control the driving source 231 to start rotating, so that the driving gear 232 drives the arc-shaped rack 233 to rotate in the arc groove 234, and the driven gear rotates synchronously under the driving action of the arc-shaped rack 233, and the two bevel gears 236 rotate together under the driving action of the driven gear, thereby driving the anti-wave contact part 25 to rotate. After the contact part 25 rotates to the preset angle, the controller controls the driving source 231 to stop driving, so that the active gear 232 stops rotating, and the arc-shaped rack 233, the passive gear and the two bevel gears 236 no longer rotate, and the wave-proof contact part 25 remains stationary, and its impact contact surface faces the flow direction of the liquid, completing the posture adjustment of the impact contact surface. Afterwards, if the direction of the fluid continues to change, repeat the above operation and continue to adjust the impact contact surface of the wave-proof contact part 25. In this way, the impact contact surface of the wave-proof contact part 25 can always be concerned about the flow direction of the liquid, thereby achieving an effective wave-proof effect on the liquid.

[0043] Please refer to Figure 6 to Figure 7 The sensing part 22 includes a pendulum ball 221 and an angle measuring device 222. The angle measuring device 222 can be an angle sensor. The top end of the pendulum ball 221 is hinged to the upper end of the mounting part 21. The bottom end of the pendulum ball 221 is lower than the liquid level of the liquid storage tank body 1 when the liquid storage volume is maximum. The angle measuring device 222 is fixed to a side of the mounting part 21 close to the pendulum ball 221. The angle measuring device 222 is connected to the controller signal. The angle measuring device 222 is used to measure the swing angle of the pendulum ball 221 and the tilt angle of the anti-wave contact part 25 in real time, and send the measurement results to the controller.

[0044] It should be noted that when the sensing part 22 is in use, the angle of the pendulum ball 221 when it is in a vertical state is recorded as 0 degrees, the angle measured when the pendulum ball 221 swings to the right is recorded as a positive angle, and the angle measured when it swings to the left is recorded as a negative angle. Since the liquid shakes slightly, there is no need to adjust the angle of the wave-proof contact part 25 to release the waves. Therefore, the angle at which the pendulum ball 221 triggers the wave-proof contact part 25 to flip can be set to a range, which can generally be set to ±20 degrees. After the angle sensor measures and detects that the swing angle of the pendulum ball 221 exceeds ±20 degrees, the angle sensor measures the angle of the wave-proof contact part 25 again, and records the tilt of the wave-proof contact part 25 to the right as a positive value, and the tilt to the left as a negative value. The detected result is then sent to the control. At this time, if the swing angle of the pendulum ball 221 and the wave-proof contact part are both positive values Or both are negative values, it means that at this time the wave-proof contact part 25 is not facing the flow direction of the liquid, and the controller needs to control the driving source 231 to rotate, so as to drive the wave-proof contact part 25 to flip to an angle relative to the flow direction of the liquid. If the swing angle of the pendulum ball 221 and the wave-proof contact part are one positive value and the other is a negative value, it means that at this time the wave-proof contact part 25 is relative to the flow direction of the liquid, and there is no need to adjust the angle of the wave-proof contact part 25. In this way, by judging the swing angle of the pendulum ball 221 and the angle of the wave-proof contact part 25 in real time, the direction of the wave-proof contact part 25 can be adjusted synchronously and in real time according to the change of the liquid flow direction. On the one hand, it can ensure that the wave-proof contact part 25 has an effective wave-proof effect on the liquid, and on the other hand, it can also protect the wave-proof contact part 25 to prevent the liquid from impacting the side that is not resistant to pressure and shortening its service life.

[0045] Please refer to Figure 4 , Figure 11 to Figure 12, since the wave-proof contact part 25 is rotatably connected to the mounting part 21, when it is not adjusted, when the liquid collides with the wave-proof contact part 25, it will cause relative shaking, which will affect the wave-proof effect of the wave-proof contact part 25. Therefore, in order to solve this problem, the present invention designs a locking part 24, which is used in conjunction with the driving part 23. Specifically: the locking part 24 includes an unlocking movable body 241 and three clamping components. The unlocking movable body 241 is slidably installed in the arc groove 234, and its end is fixed to one end of the arc-shaped rack 233. The unlocking movable body 241 is connected to the three clamping components, and the three clamping components are correspondingly connected to the rotating ends of the three wave-proof contact parts 25. The clamping components are used to clamp and lock the rotating end of the wave-proof contact part 25. When the arc-shaped rack 233 is active, the unlocking movable body 241 can synchronously trigger the three clamping components to release the clamping effect on the rotating end of the wave-proof contact part 25. When the arc-shaped rack 233 stops moving, the clamping component clamps and locks the rotating end of the wave-proof plate 251 again. The clamping assembly includes a movable block 242, a locking clamping shaft 243 and a return spring 244. The movable block 242 is slidably installed in the mounting portion 21, the locking clamping shaft 243 is fixedly installed on one side of the movable block 242, and the return spring 244 is fixedly installed between the movable block 242 and the mounting portion 21. A matching clamping groove 245 is provided at one end of the wave-proof contact portion 25 that rotates with the mounting portion 21. One end of the locking clamping shaft 243 is clamped with the matching clamping groove 245. The locking clamping shaft 243 can be a regular hexagonal prism, and the matching clamping groove 245 is a regular hexagonal prism groove. After the two are clamped, the wave-proof contact portion 25 can be prevented from rotating. An extrusion groove 246 is provided on one side of the movable block 242. The unlocking movable body 241 is an arc plate. The outer arc surface of the arc plate is provided with three extrusion protrusions corresponding to the extrusion groove 246, and the extrusion protrusions slide in cooperation with the extrusion groove 246.

[0046] It should be noted that when the driving part 23 starts to adjust the angle of the wave-proof contact part 25, the driving source 231 first drives the active gear 232 to rotate, so that the active gear 232 drives the arc-shaped rack 233 to rotate. At this time, since the tooth segment of the inner arc surface of the arc-shaped rack 233 has not yet meshed with the passive gear, when the arc-shaped rack 233 rotates, it will not temporarily drive the passive gear to rotate, and the arc plate is driven by the arc-shaped rack 233 and begins to move in the arc groove 234, so that the extrusion protrusion on it extends into the extrusion groove 246, and generates an outward force on the extrusion groove 246, which can drive the movable block 242 to retract into the mounting part 21, so that the locking card shaft 243 is separated from the matching card groove 245, and the reset spring 244 is squeezed by the movable block 242 and synchronously retracts. When the tooth segment of the inner arc surface is meshed with the passive gear, the locking card shaft 243 is completely separated from the matching card groove 245. At this time, the locking effect on the wave-proof contact part 25 is released. Then, the arc-shaped rack 233 moves to drive the wave-proof contact part 25 to flip. After the wave-proof contact part 25 flips, the matching card groove 245 and the locking card groove are aligned again, and the arc plate is continued to move through the arc-shaped rack 233. At this time, the tooth segment of the inner arc surface of the arc-shaped rack 233 is no longer meshed with the passive gear, so that the wave-proof contact part 25 is no longer active. Afterwards, the extrusion protrusion follows the arc plate to move and separates from the extrusion groove 246, and the locking card shaft 243 is again engaged with the matching card groove 245 under the elastic force of the reset spring 244 to lock the rotating end of the wave-proof contact part 25.

[0047] It can be seen from this that the locking part 24 provided in the present invention, by being used in conjunction with the driving part 23, realizes the function of automatically and synchronously unlocking the three wave-proof contact parts 25, and can be automatically completed when the driving part 23 drives the wave-proof contact part 25 to flip over. After flipping over, the wave-proof contact part 25 can be automatically locked again, and there is no need to separately control the locking or unlocking of the wave-proof contact part 25. When the driving part 23 is used alone, it can be used to drive the wave-proof contact part 25 to flip over, and when used in conjunction with the locking part 24, it is used to synchronously adapt the locking and unlocking of the wave-proof contact part 25.

[0048] Please refer to Figure 4 , Figures 8 to 10The wave-proof contact portion 25 includes a wave-proof plate 251 and a connecting component with a buffering function. The wave-proof plate 251 is detachably connected to the connecting component. One end of the connecting component is rotatably connected to the mounting portion 21, and the other end is fixed to one side of the bevel gear 236. The connecting assembly includes a connecting frame 252, and a mounting groove 253 is provided on one side of the wave-breaking plate 251. The connecting frame 252 is snapped into the mounting groove 253. The connecting frame 252 and the wave-breaking plate 251 are fixed by bolts. By setting the two in a detachable form, the wave-breaking plate 251 can be easily replaced. In addition, the connecting frame 252 is adapted to the length of the wave-breaking plate 251, and the connecting frame 252 and the mounting groove 253 are snapped together, which can also increase the support and impact resistance of the wave-breaking plate 251 and reduce the internal stress of the wave-breaking plate 251 when it is hit; sliders 254 are slidably installed at both ends of the connecting frame 252, and a support spring 255 is fixed between the slider 254 and the connecting frame 252, one of the sliders 254 is rotatably connected to the mounting portion 21, and the other slider 254 is fixed to one side of the bevel gear 236.

[0049] It should be noted that when the wave-proof contact part 25 is in use, when liquid collides with it, the force generated can make the wave-proof plate 251 and the connecting frame 252 move together, while the slider 254 remains in position, and the support spring 255 begins to shrink due to the squeezing of the connecting frame 252. The shrinkage movement of the support spring 255 can buffer the force generated by the liquid to reduce the degree of shaking of the liquid. In this way, the wave-free contact part provided by the present invention, through the provision of a connecting component, not only enables the wave-free contact part to have its own buffering capacity, but also can buffer the impact force brought by part of the liquid, thereby further enhancing the wave-free effect on the liquid. At the same time, it has good overall impact resistance, thereby reducing the damage to it caused by the impact force of the liquid.

[0050] Please refer to Figure 6 The mounting portion 21 may be a circular ring body 211, which may be welded or bolted to the inner side of the liquid storage tank body 1. A drainage slot 212 is provided at one end of the circular ring body 211 close to the inner bottom wall of the liquid storage tank body 1. The drainage slot 212 is provided to facilitate the discharge of liquid. A circular ring-shaped reinforcing panel 213 is provided on one side of the circular ring body 211. The reinforcing panel 213 may increase the connection stability between the mounting portion 21 and the liquid storage tank body 1, so as to enhance the impact resistance of the mounting portion 21.

[0051] An example of the present specific implementation mode is described above, but the present embodiment is not limited to the above-mentioned specific implementation mode, which is merely illustrative and not restrictive. A person skilled in the art may make many forms inspired by the present embodiment, all of which are protected by the present embodiment.
