DETAILED DESCRIPTION

[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0029] Embodiment 1

[0030] like Figure 1-5 As shown, a floating oil extraction device for water surface used in municipal water conservancy projects comprises a mounting plate 1, a water suction mechanism 2 and an oil-water separation component 3. The oil-water separation component 3 is arranged on the top of the mounting plate 1, and the water suction mechanism 2 is arranged on the bottom of the oil-water separation component 3. An air cushion 11 is fixedly installed on the bottom end of the mounting plate 1, and penetrating openings 111 are provided at the axis of the mounting plate 1 and the top of the air cushion 11; the oil-water separation component 3 sucks oil and water in the water area through the water suction mechanism 2 to separate oil and water, and the air cushion 11 installed on the bottom end of the mounting plate 1 allows the oil-water separation component 3 to float on the water surface for a long time to work.

[0031] A water suction mechanism 2 is arranged on the mounting plate 1, and the water suction mechanism 2 comprises a water pump 21 and a pump mounting frame 211. The water pump 21 is fixedly suspended at the upper port of the opening 111 through the pump mounting frame 211. The input end of the water pump 21 is fixedly connected with a water inlet pipe 23, and the other end of the water inlet pipe 23 is fixedly connected with a five-way connecting pipe 231. The input ends of the five-way connecting pipes 231 are all fixedly installed with water distribution pipes 24, and the output end of the water pump 21 is fixedly installed with a water outlet pipe 22; the water pump 21 is suspended on the opening 111 through the pump mounting frame 211, and the water pump 21 absorbs oil and water in the water area through multiple water distribution pipes 24 at the bottom. Multiple water distribution pipes 24 can increase the water suction area, and the water pump 21 transports water to the oil-water separation component 3 through the water outlet pipe 22 for oil-water separation.

[0032] The oil-water separation assembly 3 includes a separation box 31 and a support rod 311. The separation box 31 is opposite to the axis of the opening 111. The separation box 31 is fixedly mounted on the top of the mounting plate 1 through the support rod 311. Two partitions 32 are symmetrically installed in the separation box 31 along its height direction. The two partitions 32 divide the separation box 31 into three parts: two water filter grooves 33 and an oil filter groove 34. The oil filter groove 34 is located between the two water outlet pipes 22. A connecting groove 331 begins at the bottom end of the partition 32. The two water filter grooves 33 are connected to the oil filter groove 34 through the two connecting grooves 331. When oil and water enter the oil filter groove 34, since the density of oil is smaller than that of water, the oil will float on the water surface, and the water flows into the water filter grooves 33 on both sides through the connecting grooves 331 to achieve oil-water separation.

[0033] The top end of the water outlet pipe 22 extends to the upper part of the oil filter tank 34. Two water outlets 332 are symmetrically installed on both sides of the separation box 31 along its width direction. The two water outlets 332 are respectively connected to the two water filter tanks 33; as the water level rises, the water in the water filter tank 33 flows out through the water outlets 332, thereby realizing the effect of circulating oil filtering.

[0034] Furthermore, guide rods 36 are symmetrically installed on the inner bottom wall of the separation box 31, and the top ends of the two guide rods 36 extend to the upper part of the oil filter tank 34. Floating plates 37 are provided on the two guide rods 36. Penetrating sliding holes 371 are symmetrically provided on both sides of the floating plates 37 away from the axis thereof. The two sliding holes 371 are adapted to the two guide rods 36, and water-permeable grooves 372 are equidistantly provided on the floating plates 37. By arranging the floating plates 37 to float in the oil filter tank 34, when the water outlet pipe 22 draws oil and water into the oil filter tank 34, the water flow will first hit the floating plates 37 when it falls, thereby slowing down the falling force of the oil and water, thereby avoiding the bypass flow through the connecting groove 331 into the water filter tank 33 due to excessive impact force when the water flow falls.

[0035] Furthermore, threaded holes 361 are formed at the top ends of the guide rods 36, and threaded limit blocks 362 are threadedly installed in the threaded holes 361. The circumferential size of the top ends of the threaded limit blocks 362 is larger than the inner wall diameter of the sliding hole 371. By setting the threaded limit blocks 362, the floating plate 37 is limited on the two guide rods 36 to prevent the floating plate 37 from floating away.

[0036] Furthermore, the top of the separation box 31 is open, and a cover plate 35 is hingedly installed at the upper end of the separation box 31. The cover plate 35 is provided to facilitate cleaning of the separation box 31.

[0037] Furthermore, a handle 351 is fixedly mounted on the cover plate 35 at one end away from the hinged connection with the separation box 31 , and the handle 351 is provided to facilitate the use of opening the cover plate 35 .

[0038] Furthermore, hangers 12 are installed at the four corners of the bottom end of the mounting plate 1, and counterweights 14 are set on the four hangers 12. The four counterweights 14 are tied to the four hangers 12 by connecting ropes 13. By setting counterweights 14 at the four corners of the bottom end of the mounting plate 1, the center of gravity of the air cushion 11 is strengthened like an anchor, thereby preventing the air cushion 11 from swimming unnecessarily when floating.

[0039] Embodiment 2

[0040] like Figure 3 and Figure 6 As shown, one end of the plurality of water distribution pipes 24 away from the five-way connecting pipe 231 is fixedly installed with a filter pipe 25, and the other end of the filter pipe 25 is fixedly installed with a buoy 251, and the buoy 251 is hemispherical; by setting the filter pipe 25, it is possible to prevent leaves or garbage on the water surface from being accidentally sucked into the device during the pumping operation, causing blockage inside the device and affecting the efficiency of the device. The buoyancy of the buoy 251 is used to drive the water distribution pipe 24 to always float under the water surface, so as to facilitate the absorption of oil on the water surface and increase the working efficiency of oil-water separation.

[0041] It should be noted that the specific installation method of the water pump 21, the connection method of the oil circuit and the control method used in the present invention are all conventional designs, and the present invention will not elaborate on them in detail.

[0042] The working principle of the utility model is as follows: the air cushion 11 is used to make the oil-water separation component 3 on the mounting plate 1 float on the water surface, and the water pump 21 is started to extract water in the water area into the oil-water separation component 3. When the oil and water enter the oil filter groove 34, since the density of oil is smaller than that of water, the oil will float on the water surface, and the water flows into the water filter grooves 33 on both sides through the connecting groove 331 to achieve oil-water separation. As the water level rises, the water in the water filter groove 33 flows out through the water outlet 332, thereby achieving the effect of circulating oil filtering.

[0043] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
