In addition, different spilled oil recovery devices can be assembled on the bearing piece 100 according to working conditions, so that the spilled oil recovery device can adapt to different working conditions, and the adaptation range of the spilled oil recovery device is wider; the spilled oil 600 with different working conditions can be treated in a targeted manner, so that the spilled oil recovery equipment has higher treatment efficiency on the spilled oil 600.
As shown in fig. 1 to 3, in an alternative embodiment, at least two spilled oil recovery devices comprise a first recovery device 410, the dirt storage device comprises a dirt storage tank 210, the dirt storage tank 210 is arranged on the carrier 100, the first recovery device 410 comprises a shovel 411, a driving mechanism 412, a collecting arm 413 and a first conveying mechanism 414, the dirt storage tank 210 is provided with a feed opening 211 for the spilled oil 600 to enter, and the driving mechanism 412 is arranged on the shovel 411. Alternatively, the first conveying mechanism 414 may be a conveying device such as a belt conveyor, a chain scraper conveyor, or the like. The feeding opening 211 may be provided on the top surface or the side surface of the tank 210, and may be selected according to practical situations. The shovel 411 is provided at the end of the carrier 100 in the direction in which the spilled oil recovery device advances, that is: the shovel 411 is provided in front of the spilled oil recovery device.
The shovel 411 has a connection end 501 and a shovel oil end 502 which are oppositely disposed, the connection end 501 is connected with the carrier 100, the shovel 411 is obliquely disposed, and in the vertical direction, the height of the connection end 501 is greater than the height of the shovel oil end 502 of the shovel 411. The oil shoveling end 502 of the shoveling plate 411 may be plate-shaped, and the oil shoveling end 502 has a smaller thickness; or, in the case of a larger thickness of the oil-shoveling end 502, an inclined plane may be disposed on the top surface of the oil-shoveling end 502, so as to facilitate the shoveling of the spilled oil 600 on the beach onto the shoveling plate 411. Note that, the height of the oil-shoveling end 502 is the distance between the oil-shoveling end 502 and the ground plane, and the height of the connection end 501 is the distance between the connection end 501 and the ground plane.
The first conveying mechanism 414 is connected to the carrier 100, and the discharge end of the first conveying mechanism 414 extends to the feeding opening 211, that is, the position of the discharge end of the first conveying mechanism 414 is adapted to the position of the feeding opening 211, so that the material conveyed by the first conveying mechanism 414 can enter the dirt storage tank 210 from the feeding opening 211, and the feeding end of the first conveying mechanism 414 extends to the shovel 411. A drive mechanism 412 is connected to the collection arm 413, and the drive mechanism 412 is configured to drive the collection arm 413 to reciprocate for pushing the spilled oil 600 at the shovel end 502 of the shovel 411 to the feed end of the first delivery mechanism 414.
The working conditions for which the first recovery device 410 is suitable are: flat mud flat. The specific operation process is as follows: the walking component 300 drives the carrier 100 and the first recovery device 410 to travel, at this time, the oil shoveling end 502 of the shovel plate 411 contacts with the surface of the mud flat, the bottom surface of the oil shoveling end 502 can attack below the oil dirt layer, and the shovel plate 411 can shovel up the spilled oil 600 on the mud flat while moving forward, namely: the spilled oil 600 is separated from the mud flat, the travelling mechanism continues to push forward, the spilled oil 600 can enter the oil shoveling end 502 of the shovel plate 411, at this time, the driving mechanism 412 drives the collecting arm 413 to push the spilled oil 600 accumulated at the oil shoveling end 502 to the feeding end of the first conveying mechanism 414, and then the spilled oil 600 enters the dirt storage tank 210 through the discharging end of the first conveying mechanism 414, so that the spilled oil 600 is collected.
The first recovery device 410 may also use a vacuum cover to suck the spilled oil 600 into the dirt storage device by using negative pressure, and because the spilled oil 600 is attached to the gravel and the silt, the gravel and the silt are sucked into the vacuum cover at the same time when the spilled oil 600 is sucked into the vacuum cover by using the negative pressure, and at the moment, the gravel and the silt may block a pipeline between the vacuum cover and the dirt storage device, and to avoid the gravel and the silt from blocking the pipeline, a filter screen may be added into the vacuum cover to avoid the gravel and the silt from entering the pipeline, but because the spilled oil 600 is attached to the gravel and the silt, most of the spilled oil 600 is sucked into the dirt storage device by using the negative pressure, but part of the spilled oil 600 remains on the surface or inside of the gravel and the silt, and the part of the spilled oil 600 also pollutes the environment; in addition, if the spilled oil 600 with higher viscosity exists on the beach, the spilled oil 600 may not be thoroughly sucked away by using negative pressure, so that the recovery capability of the spilled oil 600 is weaker. In the first recovery device 410 according to the embodiment of the present application, even the high viscosity spilled oil 600 is scooped up by the scooping plate 411 and then is transported into the dirt storage tank 210 by the first transporting mechanism 414, and the first device using the scooping plate 411 has no pipeline, so that the problem of blockage is not required to be considered, and meanwhile, the spilled oil 600, the gravel and the sludge are scooped up, and the spilled oil 600, the gravel and the sludge are recovered into the dirt storage tank 210 together. Therefore, the first recovery device 410 of the present embodiment has strong recovery capability for the spilled oil 600 with higher viscosity, and can clean the spilled oil 600 on the beach more thoroughly.
As shown in fig. 1, when the first conveying mechanism 414 is disposed obliquely, and the inclination angle of the first conveying mechanism 414 is large, or the viscosity of the spilled oil 600 is low, the spilled oil 600 may slide downward along the conveying surface of the first conveying mechanism 414, so that a part of the spilled oil 600 cannot be recovered into the dirt tank 210. Alternatively, the first conveying mechanism 414 includes a second endless conveying member 506 and a second baffle 509, where the second endless conveying member 506 is an endless member such as a belt or a chain plate, and the second baffle 509 is disposed on an outer surface of the second endless conveying member 506, and the second baffle 509 is disposed in a plurality at intervals along a conveying direction of the second endless conveying member 506. After the second baffle 509 is provided, the second baffle 509 can prevent the spilled oil 600 from sliding downward, so as to avoid the problem that the spilled oil 600 cannot be recovered into the dirt storage tank 210. Further, the second leakage preventing walls 508 are disposed at two ends of the outer surface of the second annular member in the width direction, so that the spilled oil 600 can only move along the conveying direction, and the problem that the spilled oil 600 is separated from the second annular member due to the movement of the spilled oil 600 along the width direction of the second annular member can be avoided.
Optionally, the collecting arm 413 may be flat, the collecting arm 413 may be obliquely attached to the oil-shoveling end 502 of the shovel 411, the driving mechanism 412 includes a fourth telescopic member, and the fourth telescopic member drives the collecting arm 413 to push the spilled oil 600 at the oil-shoveling end 502 to the feeding end of the first conveying mechanism 414, but the fourth telescopic member is closer to the oil-shoveling end 502, and during the recovery process of the spilled oil 600, the spilled oil 600 easily flows onto the fourth telescopic member, and may cause damage to the fourth telescopic member. In another alternative embodiment, the collecting arm 413 extends from the oil shoveling end 502 of the shovel 411 towards the direction close to the connecting end 501, the collecting arm 413 includes a stirring portion 503 and a connecting portion 510 connected to the stirring portion 503, the stirring portion 503 is disposed close to the oil shoveling end 502 compared to the connecting portion 510, the stirring portion 503 is bent towards the direction close to the first conveying mechanism 414 compared to the connecting portion 510, the connecting portion 510 is hinged to the shovel 411, the hinge axis of the connecting portion 510 may be perpendicular to the top surface of the shovel 411, or an included angle exists between the hinge axis and the top surface of the shovel 411, the driving mechanism 412 is connected to the connecting portion 510, and the driving mechanism 412 may drive the stirring portion 503 to push the oil spill 600 located at the oil shoveling end 502 of the shovel 411 to the feeding end of the first conveying mechanism 414. The collecting arm 413 of the present embodiment is provided with a stirring portion 503 and a connecting portion 510, the stirring portion 503 is used for pushing the spilled oil 600, the driving mechanism 412 is connected with the connecting portion 510, and the distance between the connecting portion 510 and the oil-shoveling end 502 is large, so that the spilled oil 600 is not easy to flow onto the driving mechanism 412, and therefore, the risk of damaging the driving mechanism 412 by the spilled oil 600 can be reduced in the present embodiment.
Alternatively, the driving mechanism 412 may be a telescopic mechanism such as an air cylinder, a hydraulic cylinder, or an electric cylinder, where the hinge point between the connecting portion 510 and the shovel 411 is a first hinge point, and the connecting portion 510 is driven to reciprocate around the first hinge point by the telescopic mechanism, so as to drive the material stirring portion 503 to reciprocate; however, the time for the telescoping mechanism to complete one telescoping action is long, that is, the movement of the kick-out portion 503 is slow, so that the recovery efficiency of the spilled oil 600 is low in this embodiment. Thus, in an alternative embodiment, drive mechanism 412 includes a drive source 504 and a coupling plate 505 coupled to drive source 504, drive source 504 is provided on blade 411, and drive source 504 can drive coupling plate 505 to rotate. Alternatively, the drive source 504 may be an electric motor, a hydraulic motor, or the like.

The first recovery device 410 further includes a driven rod 415, one end of the driven rod 415 is hinged to the shovel 411, the other end of the driven rod 415 is hinged to one end, far away from the stirring portion 503, of the connecting portion 510, and the driven rod 415 can limit the rotation angle of the connecting portion 510 and the stirring portion 503. As shown in fig. 3, the specific operation procedure is as follows: when the collecting arm 413 starts to collect the spilled oil 600, the driving source 504 drives the connecting disc 505 to rotate, the connecting disc 505 rotates and drives the connecting portion 510 to reciprocate around the second hinge point, and further drives the stirring portion 503 to reciprocate, and a movement track of the bottom end of the stirring portion 503 between the oil shoveling end 502 and the feeding end of the first conveying mechanism 414 is similar to a pea profile, specifically please refer to a dashed movement track shown in fig. 3. Therefore, compared with the telescopic mechanism, the driving source 504 of the present application can make the stirring portion 503 move rapidly, that is, the driving source 504 can drive the bottom end of the stirring portion 503 to move repeatedly along the dashed moving track, so as to realize efficient recovery of the spilled oil 600.
Optionally, the bottom surface of the collecting arm 413 is provided with a flexible wiper strip to reduce the risk of oil spill 600 flowing out of the gap between the collecting arm 413 and the blade 411, thereby enhancing the recovery effect of the oil spill 600.
Optionally, the edges of the shovel 411, except the edge near the shovel oil end 502, are further provided with a first baffle 507, the first baffle 507 protrudes out of the top surface of the shovel 411, and the first baffle 507 can avoid the risk that the spilled oil 600 entering the shovel 411 flows out from the edges except the shovel oil end 502.
