Description

Technical Field

[0001] This invention relates to the field of oil depot emergency rescue technology, specifically a mobile oil depot emergency rescue device. Background Technology

[0002] In the production, storage, and transportation processes of the petrochemical industry, oil depots, as core facilities for the centralized storage of oil products, are directly related to the regional ecological environment, public safety, and economic stability through their safe operation. Mobile oil pumping trolleys are an essential emergency equipment for aviation kerosene storage depots. They are mainly used for the treatment of oily wastewater during oil tank cleaning and for emergency response to oil spills. They are widely used in oil depots of all sizes. A typical oil pumping trolley integrates an oil pump and a storage tank. In order to draw oil from the oil depot, the existing oil pumps on oil pumping trolleys usually use oil pipes to extract the oil from the oil depot.

[0003] A Chinese patent (publication number: CN118343192A) discloses an emergency oil pumping trolley for oil depots, including a T-shaped base plate and a storage tank. A hand-cranked pump is installed on the top outer wall of the T-shaped base plate, and the output end of the hand-cranked pump is connected to the storage tank through a hollow tube. A U-shaped frame is installed on the top outer wall of the T-shaped base plate. The side wall of the oil pipe is cleaned by a lower pressure plate and a sponge pad on the fixed base plate, so that the dust on the oil pipe can be cleaned after the oil pipe is retracted. By moving the movable push blocks at both ends of the bidirectional threaded rod simultaneously, the transverse connecting plate is moved downward, so that the bottom of the supporting base plate can contact the ground, which helps to improve the stability of the trolley when it is fixed and avoids displacement of the trolley during oil pumping. When the trolley is moved, the trolley will generate slight vibration. The vibration of the storage tank can be reduced by the spring shock absorber to avoid excessive sloshing of the oil inside the storage tank, which would affect the stability of the trolley when it moves.

[0004] During use, the aforementioned equipment uses an oil pump to draw oil into a storage tank. However, during the extraction process, different types of stored oil have different viscosities, such as low-viscosity diesel, high-viscosity heavy oil, or oil-water mixtures. Since the equipment extracts the stored oil through a fixed-port pipe, low-viscosity stored oil may cause the pump to suck dry due to excessively high flow rates, while high-viscosity stored oil may cause oil to overflow from the suction hose due to excessively slow flow rates.

[0005] To address these issues, we designed a mobile oil depot emergency rescue device. Summary of the Invention

[0006] The purpose of this invention is to provide a mobile oil depot emergency rescue device to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the present invention provides a mobile oil depot emergency rescue device, including a transport vehicle. A sludge pump is connected to the top of the transport vehicle, and a storage tank communicating with the sludge pump is also connected to the top of the transport vehicle. The oil-drawing end of the sludge pump is connected to a connecting pipe, and a fixed plate is connected inside the connecting pipe. The fixed plate has multiple first guide slots, and a connecting column is slidably connected to each of the first guide slots. A sealing plate is connected to each connecting column, and a rotating disk is slidably connected to the side of the sealing plate away from the fixed disk. The rotating disk has multiple second guide slots, and the connecting column is slidably connected to each of the second guide slots. An adjustment mechanism for adaptively adjusting the rotation of the rotating disk is provided inside the connecting pipe.

[0008] Furthermore, the adjusting mechanism includes a movable block slidably connected inside the connecting pipe, a threaded rod rotatably connected to one side of the movable block, a fixing nut fixedly connected inside the connecting pipe, the threaded rod being threadedly connected to the fixing nut, a telescopic rod connected to one end of the threaded rod away from the movable block, the other end of the telescopic rod being connected to a rotating disk, and a first return spring sleeved on the threaded rod.

[0009] Furthermore, a cavity is provided on the rotating disk, and a second return spring is connected inside the cavity. The other end of the second return spring is connected to a connecting plate, and a limiting ball is connected to the connecting plate. A fixing ring is connected inside the connecting tube, and multiple limiting ports are provided on the fixing ring for the limiting ball to be inserted.

[0010] Furthermore, two symmetrical fixing blocks are connected inside the connecting pipe, and the fixing nut is connected between the two fixing blocks.

[0011] Furthermore, there are two telescopic rods, both of which are inclined and arranged in a figure-eight shape.

[0012] Furthermore, a sealing sleeve is fitted onto the sealing plate.

[0013] Furthermore, a filter box is connected to the top of the transport vehicle, and multiple filter plates are connected inside the filter box, with the aperture of the multiple filter plates decreasing sequentially along the feeding direction.

[0014] Furthermore, a fixed seat is connected to the top of the transport vehicle, and the top of the fixed seat is connected to the bottom of the filter box. The filter box, connecting pipe, sludge pump and storage box are arranged in sequence along the feeding direction.

[0015] Furthermore, the number of storage tanks is at least two, and the top of each storage tank is connected to a diversion pipe. The diversion pipe and the sewage pump are interconnected through a conveying pipe.

[0016] Furthermore, a handle is connected to one side of the transport vehicle, and an anti-slip sleeve is fitted onto the handle.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. The oil first passes through filter plates with decreasing apertures inside the filter box, sequentially intercepting large particles and fine suspended matter. This prevents impurities from damaging the sludge pump or jamming the regulating mechanism. For low-viscosity oils, the moving block, under pressure, drives the threaded rod and telescopic rod to rotate the rotating disk, causing the sealing plate to converge and narrow the channel aperture, preventing the sludge pump from sucking dry. For high-viscosity oils, the spring rebound pushes the structure in the opposite direction to widen the aperture, preventing oil spillage from the hose. Simultaneously, the diversion pipe can control the flow of oil into one or more storage tanks, improving emergency operation efficiency.

[0018] 2. The second return spring inside the rotating disk cavity pushes the limiting ball to fit tightly against the fixed ring. When the rotating disk rotates to the appropriate aperture, the ball is embedded in the limiting port and locked in position to prevent the aperture from shifting due to oil impact. If the oil viscosity changes, the pressure generated by the change can drive the structure to overcome the force of the second return spring to unlock and readjust. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figure 1-6 This invention provides a technical solution: a mobile oil depot emergency rescue device, including a transport vehicle 1, a sludge pump 2 connected to the top of the transport vehicle 1, a storage tank 3 connected to the sludge pump 2 and connected to the top of the transport vehicle 1, a connecting pipe 24 connected to the oil suction end of the sludge pump 2, a fixed plate 4 connected inside the connecting pipe 24, a plurality of first guide slots 5 opened in the fixed plate 4, a connecting column 6 slidably connected in the first guide slots 5, a sealing plate 7 connected on the connecting column 6, a rotating plate 8 slidably connected to the side of the sealing plate 7 away from the fixed plate 4, a plurality of second guide slots 9 opened on the rotating plate 8, the connecting column 6 slidably connected in the second guide slots 9, and an adjustment mechanism for adaptively adjusting the rotation of the rotating plate 8 is provided inside the connecting pipe 24.

[0023] In practice, when the rotating disk 8 rotates, the second guide slot 9 drives the sealing plate 7 to move radially along the first guide slot 5 via the connecting column 6, thereby changing the diameter of the central channel formed by the multiple sealing plates 7. Low-viscosity oils have high fluidity and are prone to cavitation in the pump body due to excessive flow rate. At this time, the adjusting mechanism drives the rotating disk 8 to rotate, pulling the sealing plates 7 towards the center through the connecting column 6, reducing the diameter of the central channel, reducing the oil entry speed, and preventing the pump body from forming a vacuum due to excessive suction. High-viscosity oils have high flow resistance and are prone to oil stagnation and overflow in the suction hose due to excessively slow flow rate. The adjusting mechanism drives the rotating disk 8 to rotate, pushing the sealing plates 7 to spread outward, expanding the diameter of the central channel, reducing flow resistance, and improving oil delivery efficiency.

[0024] See Figure 1-6 The adjusting mechanism includes a movable block 10 that is slidably connected in the connecting pipe 24. A threaded rod 11 is rotatably connected to one side of the movable block 10. A fixing nut 12 is fixedly connected in the connecting pipe 24. The threaded rod 11 is threadedly connected to the fixing nut 12. A telescopic rod 14 is connected to one end of the threaded rod 11 away from the movable block 10. The other end of the telescopic rod 14 is connected to the rotating disk 8. A first return spring 15 is sleeved on the threaded rod 11.

[0025] In practice, when the oil pressure changes, the moving block 10 moves axially along the pressure: when the flow rate of low-viscosity oil is fast, the moving block 10 compresses the first return spring 15 and pushes the threaded rod 11 forward along the fixed nut 12, which drives the rotating disk 8 to rotate through the telescopic rod 14; when the flow rate of high-viscosity oil is slow, the first return spring 15 rebounds and pulls the moving block 10 to reset, the threaded rod 11 moves in the opposite direction, and the telescopic rod 14 drives the rotating disk 8 to rotate in the opposite direction.

[0026] See Figure 1-6 A cavity is provided on the rotating disk 8, and a second return spring 16 is connected inside the cavity. The other end of the second return spring 16 is connected to a connecting plate 17. A limiting ball 18 is connected on the connecting plate 17. A fixing ring is connected inside the connecting tube 24. Multiple limiting ports are provided on the fixing ring for the limiting ball 18 to be inserted.

[0027] In practice, when the rotating disk 8 rotates to the corresponding specific flow orifice, the second return spring 16 pushes the connecting plate 17, causing the limiting ball 18 to embed into the limiting port of the fixed ring, locking the position of the rotating disk 8. When adjustment is required again, the oil pressure drives the rotating disk 8 to overcome the elasticity of the second return spring 16, causing the limiting ball 18 to disengage from the limiting port and unlocking the disk. This setting prevents the rotating disk 8 from rotating unexpectedly due to the impact of oil flow, ensuring the stability of the central channel orifice diameter and preventing low-viscosity oil from being sucked up again due to a sudden increase in orifice diameter, or high-viscosity oil from overflowing again due to a sudden decrease in orifice diameter.

[0028] See Figure 1-6 The connecting pipe 24 has two symmetrical fixing blocks 13 connected inside, and the fixing nut 12 is connected between the two fixing blocks 13.

[0029] In practice, two fixing blocks 13 are symmetrically fixed inside the connecting pipe 24, and the fixing nut 12 is connected between the two fixing blocks 13 to form a stable support, ensuring that the fixing nut 12 does not shift when the threaded rod 11 moves axially.

[0030] See Figure 1-6 There are two telescopic rods 14, both of which are inclined and the two telescopic rods 14 are arranged in a figure-eight shape.

[0031] In practice, when the threaded rod 11 moves axially, the two telescopic rods 14 convert the axial force into the rotational force of the rotating disk 8 by changing the tilt angle. When the threaded rod 11 moves forward, the outer telescopic rod 14 stretches and the inner telescopic rod 14 compresses, jointly pushing the rotating disk 8 to rotate. When the threaded rod 11 moves backward, the torque direction is reversed, driving the rotating disk 8 to rotate in the opposite direction. The figure-eight layout in this arrangement converts the axial thrust of the telescopic rods 14 into a larger rotational torque, so that even if the resistance of the rotating disk 8 increases due to high viscosity oil, it can still drive the rotating disk 8 to rotate.

[0032] See Figure 1-6 A sealing sleeve is fitted onto the sealing plate 7.

[0033] In practice, when multiple sealing plates 7 converge toward the center, the sealing sleeves fit together and fill the gaps between the sealing plates 7, preventing oil leakage caused by gaps between the sealing plates 7 or between the sealing plates 7 and the inner wall of the connecting pipe 24.

[0034] See Figure 1-6 The top of the transport vehicle 1 is connected to a filter box 19, and multiple filter plates 20 are connected inside the filter box 19. The aperture of the multiple filter plates 20 decreases sequentially along the feeding direction.

[0035] In practice, the oil first enters the filter box 19, and then passes through the coarse filter, medium filter and fine filter in sequence to remove impurities. After that, it enters the sludge pump 2 through the connecting pipe 24.

[0036] See Figure 1-6 The top of the transport vehicle 1 is connected to a fixed seat 22, and the top of the fixed seat 22 is connected to the bottom of the filter box 19. The filter box 19, the connecting pipe 24, the sewage pump 2 and the storage box 3 are arranged in sequence along the feeding direction.

[0037] In practice, this feature facilitates the fixed installation of the filter box 19.

[0038] See Figure 1-6 The number of storage tanks 3 is at least two, and the top of the storage tank 3 is connected to a diversion pipe 21. The diversion pipe 21 and the sewage pump 2 are interconnected through a conveying pipe.

[0039] It should be noted that the diversion pipe 21 is equipped with a valve, which can control the flow of oil into one or more storage tanks 3.

[0040] In practice, when extracting low-viscosity oil, multiple storage tanks 3 can be opened to store oil simultaneously to avoid overflowing a single tank; when extracting high-viscosity oil, a single storage tank 3 can be selected for centralized storage.

[0041] See Figure 1-6 One side of the transport vehicle 1 is connected to a handle 23, and an anti-slip sleeve is fitted onto the handle 23.

[0042] In practice, the operator pushes the cart to move by using handle 23. The anti-slip sleeve increases the friction of the hand and prevents slipping caused by sweat or oil on the hand.

[0043] Working principle: When an oil spill occurs at the oil depot or when the oil tank needs to be cleaned and oily wastewater needs to be treated, the operator pushes the equipment to move by using the handle 23 on one side of the transport vehicle 1. The input pipeline of the oily wastewater or the oil to be extracted is connected to the inlet of the filter box 19. After the oil enters the filter box 19, it passes through multiple filter plates 20 with gradually decreasing pore size in sequence along the feeding direction. First, the large-pore filter plate 20 intercepts large particles of impurities such as oil residue and metal fragments. Then, the medium-pore and small-pore filter plates 20 remove fine suspended solids. When low-viscosity oil is encountered during extraction, its high fluidity and fast flow rate increase the impact and pressure on the moving block 10. Under pressure, the moving block 10 moves forward axially along the connecting pipe 24, compressing the outer first return spring 15 during this process. Simultaneously, it pushes the threaded rod 11, which is rotatably connected to it, to move forward synchronously. Because the threaded rod 11 and the fixing nut 12 form a threaded engagement, it ensures that the threaded rod 11 always maintains a stable axial trajectory, preventing deviation.

[0044] The forward movement of the threaded rod 11 is transmitted to the telescopic rod 14. The outer telescopic rod 14 is stretched and the inner telescopic rod 14 is compressed. The two form opposite forces and together generate a clockwise rotational torque, which drives the rotating disk 8 to rotate clockwise. When the rotating disk 8 rotates, the second guide groove 9 on its surface generates power through the connecting post 6 embedded therein. At this time, since the connecting post 6 is simultaneously engaged in the first guide groove 5 of the fixed disk 4, it is radially limited by the first guide groove 5. The rotational motion of the rotating disk 8 is converted into the radial inward movement of the connecting post 6, which in turn pulls the sealing plate 7 to converge towards the center along the first guide groove 5, reducing the diameter of the central channel formed by multiple sealing plates 7. After the diameter is reduced, the oil entry speed is reduced, effectively preventing the sludge pump 2 from forming a vacuum due to excessive suction. Similarly, high-viscosity oils have high flow resistance and slow flow rate, significantly reducing the pressure on the moving block 10. At this time, the previously compressed first return spring 15 releases its elastic force, pulling the moving block 10 back to its original position along the connecting pipe 24. The threaded rod 11 moves backward along the fixing nut 12 synchronously with the moving block 10, thereby expanding the central channel aperture. After the aperture is expanded, the oil flow resistance decreases, the conveying efficiency is improved, and oil spillage is prevented from occurring in the suction hose due to oil retention. The oil, after flow regulation, enters the sludge pump 2. The sludge pump 2 pressurizes the oil and conveys it through the conveying pipe to the diversion pipe 21. The valve on the diversion pipe 21 can control the oil to enter one or more storage tanks 3 according to the type of oil and storage requirements.
