Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle-mounted oil tanks and relates to a vehicle-mounted wave-proof oil storage tank. Background Art

[0002] The on-board oil tank is a device mounted on a tank truck for storing oil. When the tank truck accelerates or decelerates during driving, the oil inside the tank will surge and impact the tank body. Especially when the tank truck accelerates or decelerates suddenly due to collision, braking, etc., the oil inside the tank will have a stronger impact on the tank body under the action of inertia, which can easily cause damage to the tank.

[0003] Therefore, in the prior art, in order to prevent the oil surge from causing damage to the oil storage tank and the tank truck, a number of wave-breaking plates are usually welded inside the oil storage tank. The wave-breaking plates are provided with a number of through holes for the oil to pass through. When the oil hits the wave-breaking plates, the kinetic energy will be consumed, thereby reducing the impact of the oil surge on the oil storage tank. However, the wave-breaking plates inside the existing oil storage tanks are all arranged inside the oil storage tanks through fixed connection structures such as welding and bolting, resulting in a rigid impact between the wave-breaking plates and the oil. Since the mass of the oil stored in the oil storage tank is large, during the long-term oil storage and transportation process, the fixedly connected wave-breaking plates are impacted by the oil surge for a long time, which will greatly reduce the life of the wave-breaking plates. In addition, the fixedly arranged wave-breaking plates are limited in the load they can withstand from the impact of the oil. When the tank truck brakes suddenly, the wave-breaking plates may still be deformed or even damaged by the impact of the oil.

[0004] Therefore, in view of the above-mentioned defects of the existing oil storage tanks containing fixed wave-breaking plates, the utility model discloses a vehicle-mounted wave-breaking oil storage tank. Utility Model Content

[0005] The purpose of the utility model is to provide a vehicle-mounted wave-breaking oil storage tank, which effectively mitigates oil surges by arranging a fixed wave-breaking plate and an elastically sliding wave-breaking plate, while improving the bearing capacity of the wave-breaking plate itself to the oil surge load, thereby further improving the safety of the vehicle-mounted oil storage tank.

[0006] The utility model is realized by the following technical solutions:

[0007] A vehicle-mounted wave-breaking oil storage tank comprises a tank body, an oil inlet valve and an oil outlet valve are arranged on the tank body, a manhole cover is detachably installed on the top of the tank body, an intermediate wave-breaking plate is fixedly installed at the center position inside the tank body, buffer wave-breaking plates are arranged inside the tank body on both sides of the intermediate wave-breaking plate and near the end of the tank body, the buffer wave-breaking plates are slidably connected to the inside of the tank body, and a plurality of damping buffer parts are evenly distributed along the circumferential direction between the edge of the buffer wave-breaking plate and the inner wall of the tank body; through holes are arranged on the intermediate wave-breaking plate and the buffer wave-breaking plate.

[0008] When the vehicle accelerates or decelerates, the oil inside the tank flows under the action of inertia and impacts the middle wave-breaking plate and the buffer wave-breaking plate. The middle wave-breaking plate is fixedly connected to the inside of the tank. The oil impacts the middle wave-breaking plate and flows through the through holes on the middle wave-breaking plate in the tank to dissipate energy. When the oil flows to the end of the tank, the oil impacts the buffer wave-breaking plate, driving the buffer wave-breaking plate to slide inside the tank. When the buffer wave-breaking plate slides, it squeezes or stretches the damping buffer, and the elastic damping of the damping buffer further dissipates the energy of the oil, reducing the impact of the oil on the end of the tank, effectively ensuring the safety of the tank during the vehicle-mounted process.

[0009] In order to better realize the utility model, further, the damping buffer component includes a buffer cylinder, a buffer piston, a buffer rod, and a buffer spring. A buffer piston is slidably arranged inside the buffer cylinder, and the buffer piston divides the interior of the buffer cylinder into a first cavity and a second cavity. The cylinder wall of the buffer cylinder is provided with oil holes corresponding to the first cavity and the second cavity respectively, which are connected to the internal environment of the tank body; the end of the buffer piston close to the buffer wave-breaking plate is connected to the side of the buffer wave-breaking plate through the buffer rod, and a buffer spring is coaxially arranged on the outside of the buffer rod.

[0010] In order to better realize the utility model, further, a connecting hole is provided at the edge of the buffer wave-breaking plate, a connecting sleeve is provided in the connecting hole, and the connecting sleeve is connected to the end of the buffer rod.

[0011] In order to better realize the utility model, further, at least one group of axial sliding rods are arranged inside the tank body, and sliding holes which are slidably connected with the axial sliding rods are arranged at the edges of the buffer wave-breaking plates.

[0012] In order to better realize the utility model, further, a sliding guide sleeve is provided inside the sliding hole, and the sliding guide sleeve is connected with the axial sliding rod in a sliding fit.

[0013] In order to better realize the utility model, further, limit stops are arranged on both sides of the buffer wave-breaking plate on the axial sliding rod.

[0014] In order to better realize the utility model, further, a float type liquid level gauge and an electronic liquid level gauge are provided inside the tank body.

[0015] In order to better realize the utility model, further, a limited height liquid level valve is provided inside the tank body at a limited height position of the oil.

[0016] In order to better implement the utility model, further, an oil return flange is provided on one side of the manhole cover at the top of the tank body.

[0017] In order to better realize the utility model, further, a saddle support is provided at the bottom of the tank body.

[0018] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0019] (1) The utility model fixes an intermediate wave-breaking plate in the middle of the tank body, so that the oil is buffered when passing through the through holes on the intermediate wave-breaking plate, thereby effectively slowing down the surge in the middle of the tank body;

[0020] (2) The utility model slides buffer wave-breaking plates at both ends of the tank body, and arranges damping buffer components on one side of the buffer wave-breaking plates. When a surge occurs in the oil inside the tank body, the buffer wave-breaking plates are impacted, thereby compressing the damping buffer components. The elastic compression of the damping buffer components effectively dissipates energy and buffers the oil surge at the end portion of the tank body, thereby improving the tank body's carrying capacity for oil surges.

[0032] Embodiment 1:

[0033] A vehicle-mounted wave-proof oil storage tank of this embodiment, such as Figure 1-Figure 4 As shown, it includes a tank body 2, on which an oil inlet valve 6 and an oil outlet valve 7 are provided, a manhole cover 1 is detachably installed on the top of the tank body 2, an intermediate wave-breaking plate 3 is fixedly installed at the center position inside the tank body 2, and a buffer wave-breaking plate 4 is provided inside the tank body 2 on both sides of the intermediate wave-breaking plate 3 and near the end of the tank body 2, the buffer wave-breaking plate 4 is slidably connected to the inside of the tank body 2, and a plurality of damping buffer parts 5 are evenly distributed along the circumferential direction between the edge of the buffer wave-breaking plate 4 and the inner wall of the tank body 2; the intermediate wave-breaking plate 3 and the buffer wave-breaking plate 4 are both provided with through holes.

[0034] The tank body 2 is made of 304 stainless steel or Q235 steel. The two sides of the bottom of the tank body 1 are respectively provided with an oil inlet valve 6 and an oil outlet valve 7. The oil inlet valve 6 can be opened to add oil to the inside of the tank body 2, and the oil outlet valve 7 can be opened to discharge the oil inside the tank body 2. A manhole cover 1 is provided in the middle of the top of the tank body 2. The manhole cover 1 is detachably installed on the top of the tank body 2 by reinforcing bolts. By opening the manhole cover 1, the staff can enter the inside of the tank body 2 to inspect and maintain the components inside the tank body 2.

[0035] An intermediate wave-breaking plate 3 is fixedly installed in the middle position inside the tank body 2, and the edge of the intermediate wave-breaking plate 3 is welded to the inner wall of the tank body 2 or fixedly connected to the flange on the inner wall of the tank body 2 by bolts. The intermediate wave-breaking plate 3 is fixedly arranged relative to the tank body 2, and a plurality of through holes are arranged in an array on the intermediate wave-breaking plate 3. When the vehicle accelerates or decelerates, the oil impacts the intermediate wave-breaking plate 3 under the action of inertia and flows through the through holes inside the tank body 2, thereby dissipating the energy of the oil and preventing the oil from surging beyond the safety threshold inside the tank body 2. When the oil flows to the end position of the tank body 2, the oil impacts the buffer wave-breaking plate 4 and flows through the through holes on the buffer wave-breaking plate 4. At the same time, when the buffer wave-breaking plate 4 is impacted, it slides along the inside of the tank body 2, thereby squeezing or stretching the damping buffer 5. The damping buffer 5 deforms smoothly to further dissipate the energy of the oil and prevent the oil from causing excessive impact on the end of the tank body 2.

[0036] Embodiment 2:

[0037] A vehicle-mounted wave-proof oil storage tank is improved on the basis of Example 1, such as Figure 5 and Figure 6 As shown, the damping buffer component 5 includes a buffer cylinder 51, a buffer piston 52, a buffer rod 53, and a buffer spring 54. The buffer cylinder 51 is slidably provided with a buffer piston 52, and the buffer piston 52 divides the interior of the buffer cylinder 51 into a first cavity 100 and a second cavity 200. The cylinder wall of the buffer cylinder 51 is provided with oil holes corresponding to the first cavity 100 and the second cavity 200 respectively, which are connected to the internal environment of the tank body 2; the end of the buffer piston 52 close to the buffer wave-breaking plate 4 is connected to the side of the buffer wave-breaking plate 4 through the buffer rod 53, and the outside of the buffer rod 53 is coaxially provided with a buffer spring 54.

[0038] like Figure 5 and Figure 6As shown, when the buffer wave-breaking plate 4 is impacted to the left by the oil, the buffer wave-breaking plate 4 moves to the left and drives the buffer spring 54 to stretch. At this time, the buffer rod 53 drives the buffer piston 52 to move to the left inside the buffer cylinder 51. The leftward movement of the buffer piston 52 forces the oil inside the first cavity 100 to be squeezed out through the oil hole into the tank body 2, while the second cavity 200 sucks the oil in the tank body 2 through the oil hole to maintain balance, and then the elastic deformation of the buffer spring 54 and the damping movement of the buffer piston 52 are used to smoothly buffer and dissipate energy of the oil. After the oil no longer fluctuates, the buffer spring 54 returns to its original state and drives the buffer rod 53 to return to its initial position.

[0039] like Figure 5 and Figure 6 As shown, when the buffer wave-breaking plate 4 is impacted by the oil to the right, the buffer wave-breaking plate 4 moves to the right and drives the buffer spring 54 to be compressed. At this time, the buffer rod 53 drives the buffer piston 52 to move to the right inside the buffer cylinder 51. The rightward movement of the buffer piston 52 forces the oil inside the second cavity 200 to be squeezed and discharged into the tank body 2 through the oil hole, while the first cavity 100 sucks the oil in the tank body 2 through the oil hole to maintain balance, and then the elastic deformation of the buffer spring 54 and the damping movement of the buffer piston 52 are used to smoothly buffer and dissipate energy of the oil. After the oil no longer fluctuates, the buffer spring 54 returns to its original state and drives the buffer rod 53 to return to its initial position.

[0040] Furthermore, a connection hole is provided at the edge of the buffer wave-breaking plate 4, and a connection sleeve 8 is provided in the connection hole, and the connection sleeve 8 is connected to the end of the buffer rod 53. The inner hole of the connection sleeve 8 is snap-fitted or threadedly connected to the end of the buffer rod 53, and the connection sleeve 8 is connected to the buffer wave-breaking plate 4 through a connection flange.

[0041] The other parts of this embodiment are the same as those of Embodiment 1, and thus will not be described in detail.

[0042] Embodiment 3:

[0043] A vehicle-mounted wave-proof oil storage tank is improved on the basis of embodiment 1 or 2, such as Figure 1 , Figure 3 , Figure 5 As shown, at least one group of axial sliding rods 21 are arranged inside the tank body 2, and sliding holes that are slidably connected to the axial sliding rods 21 are arranged at the edge of the buffer wave-breaking plate 4.

[0044] As shown in the figure, four groups of axial slide bars 21 are evenly arranged in the circumferential direction inside the tank body 2, and four groups of sliding holes are arranged at the edge of the buffer wave-breaking plate 4 at positions corresponding to the four groups of axial slide bars 21 in the circumferential direction. Through the sliding and sliding matching connection with the axial slide bars 21, the sliding of the buffer wave-breaking plate 4 can be strictly guided to ensure the stability of the sliding process of the buffer wave-breaking plate 4.

[0045] Furthermore, a sliding guide sleeve 22 is provided inside the sliding hole, and the sliding guide sleeve 22 is connected to the axial sliding rod 21 in a sliding fit.

[0046] Furthermore, limit stops 23 are provided on both sides of the buffer wave-breaking plate 4 on the axial slide bar 21, and the limit stops 23 are provided to limit the sliding stroke of the buffer wave-breaking plate 4. When the buffer wave-breaking plate 4 slides to the limit position under the impact of the oil, the buffer wave-breaking plate 4 contacts and is limited by the limit stops 23, and the buffer wave-breaking plate 4 cannot continue to slide.

[0047] The other parts of this embodiment are the same as those of Embodiment 1 or 2, and thus will not be described in detail.

[0048] Embodiment 4:

[0049] A vehicle-mounted wave-proof oil storage tank is improved on the basis of any one of embodiments 1-3, such as Figure 2 As shown, a float type liquid level gauge 9 and an electronic liquid level gauge 10 are provided inside the tank body 2. The float type liquid level gauge 9 and the electronic liquid level gauge 10 constitute a redundant liquid level detection structure with double protection. Even if one of them fails, the liquid level height of the oil inside the tank body 2 can be detected in real time through the remaining normally working liquid level gauge.

[0050] The other parts of this embodiment are the same as any one of Embodiments 1-3, so they are not described again.

When the oil inside the tank body 2 exceeds the height of the limited height liquid level valve 11, the limited height liquid level valve 11 opens to discharge the excess oil, thereby preventing the oil storage amount inside the tank body 2 from exceeding the safety threshold.

[0053] The other parts of this embodiment are the same as any one of Embodiments 1-4, so they are not described again.
