Detailed Description
In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings.

For example, if a collision accident occurs during the sailing of an oil tanker, the oil carried by the oil tanker leaks into the water body after the hull of the oil tanker is broken, and the leaked oil floats on the water surface 50 because the specific gravity of the oil is greater than that of the water. Toxic compounds such as benzene and toluene contained in petroleum enter the food chain, ranging from lower algae to higher mammals, and none survive. For example, batches of seabirds are trapped in oil and their feathers, once soiled, can cause poisoning and even death. In addition, the oil stain is adhered to fur of seabirds, so that the seabirds cannot bear the weight of the seabirds, and drowning is caused. The seal polluted by the oil stain jumps out of the water surface 50 again and again, tries to throw off the oil stain on the fur, but finally becomes exhausted and is struggled to sink to the seabed. Large marine animals, such as hordeolum and whales, are also confronted with the same lucky. In addition, the potential damage extends even further into the ecosystem of the venue, where surviving organisms will be inherited by the offspring of several organisms during the years following impact, affected by the toxicant.
Based on this, once the oil spill dangerous situation occurs, the oil spill emergency equipment on the water needs to be used for timely recovering and salvaging the oil spill on the water surface 50, so as to reduce or eliminate the potential hazard brought by the oil spill.

The buoyancy mechanism 10 is used to float the two-stage weir oil recovery machine on the water surface 50, and forms a necessary condition for recovering spilled oil. The first-stage oil receiving equipment 30 and the second-stage oil receiving equipment 40 are used for realizing graded recovery of the spilled oil, and the oil collecting container 20 is used for carrying out second-stage separation on the spilled oil, so that necessary conditions are provided for realizing secondary recovery of the spilled oil by the second-stage oil receiving equipment 40.
Specifically, the oil collecting container 20 is disposed on the buoyancy mechanism 10; the grading oil collecting device is arranged on the oil collecting container, specifically, the first-stage oil collecting equipment 30 is arranged in the oil collecting container 20 and is used for performing first-stage separation and recovery on the spilled oil on the water surface 50; the secondary oil collecting device 40 is arranged in the oil collecting container 20 and is used for carrying out secondary separation and recovery on the spilled oil entering the oil collecting container 20.
The double-stage weir type oil recovery machine is applied to the occasion of oil spill emergency rescue, and is used for rapidly recovering and storing oil spill floating on the water surface 50, so that pollution of the oil spill to the ecological environment and water is avoided. Specifically, the double-stage weir oil recovery machine of the scheme can be installed on a small manual boat, a vehicle or directly manually carried for use when in use, is suitable for being used in places except large and wide sea areas and main navigation channels and is also suitable for being used in inland rivers, streams, lakes, reservoirs, ponds and other sheltered water bodies, firstly, the double-stage weir oil recovery machine is put into water, buoyancy is provided by the buoyancy mechanism 10, so that the whole double-stage weir oil recovery machine can safely and reliably float on the water surface 50, then, the equipment is started, the first-stage oil recovery equipment 30 firstly starts to work, overflow oil (oil-water mixture) on the water surface 50 is recovered into the oil collection container 20, the overflow oil entering the oil collection container 20 is the oil-water mixture with higher oil concentration, and the oil layer usually floats above the water layer due to different specific gravities of the oil and the water layer, so that the overflow oil in the oil collection container 20 can be subjected to secondary separation, the secondary oil recovery device 40 then initiates recovery of the higher concentration of spilled oil on the water surface 50 in the oil collection vessel 20.

The floating frame 11 is used for loading and fixing the floating body 12 and ensuring the whole structure of the floating mechanism 10 to be stable and reliable. The floating body 12 is made of light material, and the specific gravity is smaller than that of water, so that the floating body can reliably float on the water surface 50, the first-stage oil receiving equipment 30 and the second-stage oil receiving equipment 40 can float on the water surface 50 and contact an oil overflow layer, and the overflow recovery of the oil overflow is realized.
Alternatively, the floating frame 11 in this embodiment is made of light-weight but structurally strong metal, composite material, etc., such as stainless steel, rigid plastic, etc. The floating body 12 can be made of foam, air bags, PE plastic and the like, and the floating body 12 can be a cube, a cylinder, a sphere or a special-shaped body. These details can be selected according to the actual needs.
Continuing to refer to FIG. 2, preferably, in some embodiments, the buoyant frame 11 is formed as a cross-shaped structure. Correspondingly, four floating bodies 12 are arranged, and the four floating bodies 12 are distributed on the floating frame 11 in a cross shape; namely, each strut of the floating frame 11 is provided with a floating body 12. The cooperation of four floats 12 not only can produce bigger buoyancy, guarantees that doublestage weir formula oil recovery machine reliably floats in surface of water 50, and the buoyancy that four floats 12 provided distributes evenly and the size is unanimous in the horizontal plane simultaneously, makes doublestage weir formula oil recovery machine do benefit to and keeps balanced gesture to help keeping one-level oil recovery equipment 30 and second grade oil recovery equipment 40 and the contact of oil spilling layer good, promote the oil spilling recovery effect.

In this scheme, the theory of operation of two-stage weir formula oil recovery machine lies in making one-level oil recovery equipment 30 and second grade oil recovery equipment 40 press close to surface of water 50, makes the oil spilling can overflow and get into two and receive the interior realization of oil recovery equipment, and blocks most water outside to avoid water to get into more and influence the oil recovery rate. Thus, the heights of the primary oil recovery device 30 and the secondary oil recovery device 40 need to be adjusted according to the current local water body conditions and the thickness of the spilled oil on the water surface 50.
With continuing reference to fig. 1 and fig. 2, further, the dual-stage weir oil recovery machine further includes a regulating assembly 60, the buoyancy frame 11 is connected to the oil collecting container 20 through the regulating assembly 60, and the regulating assembly 60 can make the oil collecting container 20 close to or far away from the water surface 50. Because the buoyancy of the buoyancy mechanism 10 is a certain value once it is designed and manufactured, and the submergence depth of the buoyancy mechanism 10 in water is basically fixed, but the water condition and the oil spill thickness are changed values, at this time, by operating the adjusting component 60, the adjusting component 60 drives the oil collecting container 20 to move upwards (close to the buoyancy mechanism 10, i.e. close to the water surface 50) or downwards (far from the buoyancy mechanism 10, i.e. far from the water surface 50), so that the optimal height relationship between the primary oil collecting device 30 and the secondary oil collecting device 40 and the water surface 50 can be obtained, and the subsequent oil spill recovery efficiency can be ensured.
Referring to fig. 1, in detail, in some embodiments, the adjusting assembly 60 includes an adjusting bolt 61 and a locking nut 62, the adjusting bolt 61 is fixedly connected to the oil collecting container 20 through the locking nut 62, and the floating frame 11 is provided with a threaded hole, and the adjusting bolt 61 is screwed into the threaded hole. Through clockwise or anticlockwise twist adjusting bolt 61, adjusting bolt 61 can slide from top to bottom in the threaded hole to reach the purpose that the drive oil collecting container 20, one-level received oily equipment 30 and second grade received oily equipment 40 altitude mixture control, this adjusting part 60's structural component is simple, and adjustable operability is good, and the screw thread pair has the auto-lock characteristic simultaneously, can guarantee to transfer each parts position after stable.
The top of the oil collecting container 20 is provided with a through hole, and the end part of the adjusting bolt 61 passes through the through hole and then is locked with the locking nut 62 positioned inside and outside the oil collecting container 20, so that the adjusting bolt 61 and the oil collecting container 20 can be assembled into a whole.
The adjusting assemblies 60 and the threaded holes are all arranged into four and distributed in a cross shape, and are assembled and connected in a one-to-one correspondence mode. When the double-stage weir type oil recovery machine is inclined towards a certain direction, the buoyancy of the corresponding floating body 12 can be changed by adjusting the corresponding adjusting component 60, and the balance posture of the double-stage weir type oil recovery machine can be restored.
With reference to fig. 1 and fig. 2, in addition, on the basis of any of the above embodiments, a first protruding opening 21 is formed at the upper end of the oil collecting container 20, the primary oil collecting device 30 includes a primary electric oil collecting pump 31 and a primary oil collecting weir 32, the primary electric oil collecting pump 31 is disposed on the inner wall of the oil collecting container 20, the primary oil collecting weir 32 is disposed on the primary electric oil collecting pump 31 in a communicating manner, the primary oil collecting weir 32 protrudes from the first protruding opening 21, and the upper edge of the primary oil collecting weir 32 is disposed in an oil layer above the oil-water interface of the water surface 50.

The first-stage oil collecting weir 32 extends out of the first extending port 21 and extends into the oil layer above the oil-water interface of the water surface 50, so that the overflowed oil can flow into the first-stage electric oil collecting pump 31 in an overflow suction manner under the power driving of the first-stage electric oil collecting pump 31. The oil overflow outlet of the first-stage electric oil collecting pump 31 is disposed inside the oil collecting container 20, so that the oil overflow entering the first-stage electric oil collecting pump 31 finally flows into the oil collecting container 20 for temporary storage.
It will be appreciated that the oil spill entering the oil collection container 20 through the primary electric oil collection pump 31 is substantially an oil-water mixture, and is only once separated by the primary oil collection weir 32, and the oil concentration is higher.

For example, the energy supply device may be a storage battery, and after the first stage is fully charged, sufficient electric energy can be provided for the first-stage electric oil recovery pump 31 and the second-stage electric oil recovery pump 41 within a long period, so that the continuous and reliable operation of the two-stage weir oil recovery machine is ensured.
Referring to fig. 1, further, an oil stain outlet 23 is formed at the bottom end of the oil collecting container 20, and an oil discharge end 411 of the secondary electric oil collecting pump 41 penetrates through the oil stain outlet 23. The double-stage weir type oil recovery machine further comprises a storage device, the storage device is communicated with the oil discharge end 411 of the second-stage electric oil recovery pump 41, and the storage device is used for carrying out concentrated temporary storage on recovered spilled oil.
The high-concentration oil spill recovered by the secondary separation is finally discharged from the oil discharge end 411 of the secondary electric oil recovery pump 41, and is conveyed into a storage device for temporary storage, and after the oil spill cleaning work is finished, the concentrated recovery processing is performed.
