[0010] The second rotating shaft is provided with several second discs arranged side by side; the surface of the second discs is covered with oil-absorbing felt cloth;

[0011] The oil transfer trough is a U-shaped trough, and an oil squeezing plate is provided inside the oil transfer trough; the oil transfer trough and the oil squeezing plate are provided with a first opening and a second opening; the oil squeezing plate is located on one side of the first opening; the two sides of the second opening are oil guiding slopes; a portion of the second disc passes through the first opening and the second opening; there is a gap between the first opening and the oil-absorbing felt; the width of the second opening is greater than the thickness of the second disc and less than the sum of the thicknesses of the oil-absorbing felt and the second disc.

[0012] The first and second disks are staggered and partially overlap in the axial direction; the brush bristles and the oil-absorbing felt are in contact;

[0013] The buoyancy box is equipped with a first hydraulic motor and a second hydraulic motor.

The high-speed rotation of the first disc quickly transfers the oil to the second disc. The low-speed rotation of the second disc, in conjunction with the oil-squeezing plate, squeezes the oil off the oil-absorbing felt on the surface of the second disc, thus achieving oil transfer. This design has advantages such as long service life and high oil collection efficiency. Attached Figure Description

[0022] 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.

[0023] Example 1

[0024] Referring to Figures 1-5, a multi-functional land-based oil spill emergency system includes a container 1, which houses an oil recovery device and a hydraulic power unit 2 and a self-priming pump 3. The oil recovery device includes a rotary oil recovery machine 4.

[0025] The rotary oil skimmer 4 includes two buoyancy tanks 41 arranged opposite each other, a pair of first rotating shafts 42 and a pair of second rotating shafts 43 disposed between the two buoyancy tanks 41, and an oil transfer trough 44; the second rotating shafts 43 are located between the pair of first rotating shafts 42; and the oil transfer trough 44 is located between the pair of second rotating shafts 43.

[0026] The first rotating shaft 42 is provided with a plurality of first disks 45 arranged side by side; the first disks 45 are provided with multiple clumps of bristles; each clump of bristles is composed of multiple bristles 470; the projection of the bristles on the first disks 45 and the radial direction of the first disks 45 form a first angle, which is preferably 15-45°, preferably 15°, 25°, or 35°, and is selected as 25° in this embodiment; the bristles and the disk surface of the first disks 45 form a second angle, which should not be too large, preferably 10-30°, preferably 15°, 20°, or 25°, and is selected as 15° in this embodiment;

[0027] The second rotating shaft 43 is provided with a plurality of second discs 46 arranged side by side; the surface of the second discs 46 is covered with oil-absorbing felt cloth;

[0028] The oil transfer trough 44 is a U-shaped trough, and an oil squeezing plate 47 is provided inside the oil transfer trough 44. The oil transfer trough 44 and the oil squeezing plate 47 are provided with a first opening 48 and a second opening 49. The oil squeezing plate 47 is located on one side of the first opening 48. The two sides of the second opening 49 are oil guiding slopes 40. A portion of the second disc 46 passes through the first opening 48 and the second opening 49. There is a gap between the first opening 48 and the oil-absorbing felt. The width of the second opening 49 is greater than the thickness of the second disc 46 and less than the sum of the thicknesses of the oil-absorbing felt and the second disc 46.

[0029] The first disk 45 and the second disk 46 are staggered and partially overlap in the axial direction; the brush bristles and the oil-absorbing felt are in contact;

[0030] The buoyancy box 41 is equipped with a first hydraulic motor 400 and a second hydraulic motor 410. The first hydraulic motor 400 is used to drive the first rotating shaft 42; the second hydraulic motor 410 is used to drive the second rotating shaft 43; the U-shaped groove is connected to the self-priming pump 3 through the pipe 420; the first hydraulic motor 400 and the second hydraulic motor 410 are connected to the hydraulic power unit 2 through the oil supply pipe 460.

[0031] Its working process is as follows:

[0032] First, the container 1 is transported to the site where oil removal is needed by trailer or truck. Taking river oil removal as an example, the rotary oil collector 4 is placed in the river. It is connected to the hydraulic power unit 2 and the self-priming pump 3 through pipelines. The self-priming pump 3 is used to pump the floating oil in the oil transfer tank 44 to the shore. By controlling the oil supply to the two first hydraulic motors 400, the rotation speed of the two first rotating shafts 42 is controlled to achieve the forward movement of the buoyancy box 41. When it reaches the oil collection position, the first rotating shaft 42 facing the oil slick and the second rotating shaft 42 face the oil slick. When shaft 43 operates, the bristles on the first disc 45 adhere to and transfer oil stains to the more absorbent oil-absorbing felt; the bristles are made of an oleophilic and hydrophobic material; the second disc 46 rotates at a slower speed, and the oil-absorbing felt has a larger oil storage capacity. As the second disc rotates and passes through the second opening 49, the oil-absorbing felt is squeezed, releasing the grease on the oil-absorbing felt to one side of the oil-squeezing plate 47 and flowing into the floating oil transfer trough 44; compared with the traditional single design of setting multiple oil-absorbing discs on a single roller shaft, it has the following advantages:

[0033] 1. The brush bristles and the oil-absorbing felt are not in hard contact, so the brush bristles are less damaged and have a longer service life; the oil-absorbing felt is not damaged by repeated squeezing and has a strong oil storage capacity, which can fully transfer the grease into the floating oil transfer tank 44.

[0034] 2. This design allows the brush bristles to rotate at high speed, achieving high-speed oil transfer, while the oil-absorbing felt rotates at low speed, ensuring complete oil extrusion.

[0035] 3. Compared to traditional felt discs, the brush bristles are less prone to carrying water. Because the bristles need to rotate more than half a circle to come into contact with the oil-absorbing felt, as much water is removed during this process, resulting in an oil absorption moisture content of less than 1%.

[0036] This rotary oil collector has dimensions of 0.8 x 1.0 m and a collection speed of up to 40 m / s. 3 / h.

[0037] Compared to designs that simply use bristles, it has a lower moisture content, and compared to discs with a low-speed felt structure, its oil collection efficiency is at least 50% higher; the entire process runs smoothly, and grease does not splatter everywhere.

[0038] In a preferred embodiment, each first rotating shaft 42 is independently connected to a first hydraulic motor 400; each second rotating shaft 43 is independently connected to a second hydraulic motor 410; the bottom of the buoyancy box 41 is also provided with a rudder 430; the buoyancy box 41 is provided with a motor 440 and a battery 450; the rudder 430 is driven to rotate by the motor 440; the battery 450 supplies power to the motor 440; the operator remotely controls the motor 440 to rotate forward and backward, thereby realizing the rotation of the rudder 430.

[0039] In this embodiment, the oil collection equipment further includes a beach oil collector 5 and a vacuum oil collector 6; the oil collection device consists of a foldable quick-loading tank 7, a boxed oil boom 8, and an oil-absorbing felt 9. In this embodiment, both the beach oil collector 5 and the vacuum oil collector 6 have built-in hydraulic motors and are supplied with power oil by a hydraulic power unit 2, and their vacuum suction force is provided by a self-priming pump 3;

[0040] Preferably, the compartment 1 is also equipped with an oil-absorbing powder spraying device 10, which has a built-in hydraulic motor and is powered by a hydraulic power unit 2; the compartment 1 is a vehicle-mounted compartment.
