Description

Technical Field

[0001] The utility model relates to the technical field of oil pollution cleaning, in particular to a water surface floating oil extractor for water conservancy projects. Background Technique

[0002] Due to various reasons such as traffic accidents, maintenance of sluice and pumping station electromechanical equipment, some oil fluids often enter the water flow channels, directly causing water quality pollution and having a great impact on the internal water body quality. And some water sources in the river are drinking water, and the water quality pollution will directly endanger human health. Therefore, it is crucial to remove oil pollution substances in the water conveyance river.

[0003] For example, a water surface floating oil extractor for municipal water conservancy projects disclosed in the Chinese utility model patent with the publication number CN211111177U includes a main frame body, a support rod, a water collecting pipe and a water collecting tray; three floating balls are fixedly installed on the outer side of the top of the main frame body; the bottom of the main frame body is fixedly connected with a lower support plate through six connecting rods; a support rod is fixedly embedded inside the lower support plate; a rotating shaft is fixedly installed at the top of the support rod, and the top of the rotating shaft is fixedly connected with the bottom of the water collecting pipe; a water suction pipe is also embedded on one side of the water collecting pipe, and a water collecting tray is fixedly installed at the top of the water collecting pipe.

[0004] In this solution, the contact height between the water collecting tray and the water surface can be adjusted through the support rod, and the water collecting pipe will not rotate with the support rod when the support rod rotates, so the water suction pipe can be effectively prevented from winding. Moreover, the structure is obviously simpler and the operation is more convenient by using this method. And the position of the main frame body is relatively low, and the center of gravity can be effectively reduced by combining the weight of the support rod, so that the device is more stable when floating in the water.

[0005] However, in the solution of this utility model, there is no mechanism for screening floating oil, which affects the efficiency of extracting water surface floating oil. Content of the Utility Model

[0006] In order to overcome the deficiencies in the background technique, the utility model provides a water surface floating oil extractor for water conservancy projects.

[0007] The technical scheme adopted by the utility model is as follows:

[0008] An oil skimmer for a water conservancy project, comprising a support outer frame, a plurality of main floating balls fixed to the bottom of the support outer frame, and a support plate. A load box for containing floating oil is arranged on the lower side of the support outer frame. An oil pumping pipeline is fixed to the support plate, and the upper end of the oil pumping pipeline extends into the load box. An inlet plate is arranged below the support plate, and the inlet plate is rotatably installed at the lower end of the oil pumping pipeline. A plurality of suction ports are arranged on the inlet plate. An activity chamber is arranged in the middle section of the oil pumping pipeline, and a movable hollow silica ball is arranged in the activity chamber. A carrier liquid for adjusting its weight is filled in the hollow silica ball, so that the overall density of the hollow silica ball is greater than that of the floating oil but less than that of water. When the hollow silica ball moves to the outlet at the upper end of the activity chamber, the oil pumping pipeline is cut off.

[0009] In a further embodiment, a plurality of windshields are fixedly connected to the upper surface of the inlet plate, and a plurality of buoyancy balls are fixedly connected to the lower surface of the inlet plate.

[0010] In a further embodiment, the oil pumping pipeline consists of a connecting pipe, an outlet pipe, and an inlet pipe that are connected in sequence from top to bottom. A first enlarged diameter section with an enlarged diameter is arranged at the lower end of the outlet pipe, and a second enlarged diameter section with an enlarged diameter is arranged at the upper end of the inlet pipe. The activity chamber with a pore diameter larger than that of the outlet pipe is formed after the first enlarged diameter section and the second enlarged diameter section are butted.

[0011] In a further embodiment, a lower connecting disk and a lower retaining ring are arranged on the outer wall of the inlet pipe. A connecting ring is arranged on the inlet plate, and the inner hole of the connecting ring is rotatably installed on the inlet pipe between the connecting disk and the lower retaining ring.

[0012] In a further embodiment, a support inner frame is fixed inside the support outer frame. The support inner frame is fixedly connected with a plurality of vertically suspended stabilizing rods, and the lower ends of the stabilizing rods are fixedly connected with the support plate.

[0013] In a further embodiment, the support inner frame is provided with a fixing block for fixing the connecting pipe.

[0014] In a further embodiment, the load box is movably connected to the bottom of the support inner frame.

[0015] In a further embodiment, a plurality of connecting pieces for external rope threading or hooking are fixedly connected to the upper surface of the support outer frame.

[0016] In a further embodiment, a main support rod is welded to the bottom of the support outer frame. The lower end of the main support rod is fixedly connected with a main floating ball, and a horizontally arranged stabilizing piece is fixed to the outer wall of the main floating ball.

[0017] In a further embodiment, a screen is arranged on the outer side of the support outer frame.

[0018] The beneficial effects of the present utility model are as follows: In this application, the support plate is used to support the overall structure of the surface floating oil extraction structure. A hollow silicon ball is disposed inside the activity chamber formed by the first enlarged diameter section and the second enlarged diameter section. By puncturing through the first enlarged diameter section with a needle, the corresponding carrier liquid is injected into or extracted from the inside of the hollow silicon ball, so that the density of the hollow silicon ball is greater than that of the grease and less than that of water. The hollow silicon ball sinks to the bottom at the floating oil and floats up when the water rises. The second enlarged diameter section generates an oil-water mixture to lift the hollow silicon ball. Then, the oil continues to rise upward along the side of the hollow silicon ball, and the hollow silicon ball rises simultaneously with the water surface. When it reaches the lower end of the first enlarged diameter section, it blocks the first enlarged diameter section, preventing water from rising into the carrier box, and realizing the screening of floating oil and water.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] In order to enable those of ordinary skill in the art to more clearly understand the purpose, technical solutions and advantages of the present utility model, the following further elaborates on the present utility model in conjunction with the drawings and embodiments, but the present utility model is not limited to the following embodiments.

[0025] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "inner", "outer", "front end", "rear end", "both ends", "one end", "the other end", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0026] Refer to Figures 1-4, An oil skimmer for water surfaces in water conservancy projects, including a support plate 1. A through hole 25 is provided on the support plate 1, and the first enlarged diameter section 2 at the lower end of the outlet pipe 12 is fixed in the through hole 25. An inhalation pipe 6 and an inlet disk 8 are provided on the lower side of the support plate 1. The second enlarged diameter section 3 at the upper end of the inhalation pipe 6 is docked with the first enlarged diameter section 2. The inner holes of the two enlarged diameter sections form an activity chamber. The inner diameter of the activity chamber is larger than the inner diameters of the outlet pipe and the inhalation pipe 6. A movable hollow silica sphere 4 is arranged in the activity chamber.

[0027] A lower connection disk 5 and a lower retaining ring 23 are provided on the outer wall of the inhalation pipe 6. A central hole 24 is provided at the center of the inlet disk 8. A connection ring 7 is fixed at the upper opening of the central hole 24. The connection ring 7 is rotatably installed on the inhalation pipe 6 between the connection disk 5 and the lower retaining ring 23, so that the inlet disk 8 can rotate at the lower end of the inhalation pipe 6. A plurality of suction inlets 9 are provided on the inlet disk 8, and the suction inlets 9 communicate with the central hole 24. Two top covers are provided on each suction inlet 9, and the opening directions of the two top covers are opposite.

[0028] The support plate 1 is used to support the overall structure of the water surface oil skimmer. A hollow silica sphere 4 is arranged in the activity chamber formed by the first enlarged diameter section 2 and the second enlarged diameter section 3. By puncturing the hollow silica sphere 4 to inject or extract the corresponding carrier liquid into it, the density of the hollow silica sphere 4 is made greater than that of the oil and less than that of the water. The hollow silica sphere 4 sinks to the bottom at the floating oil and floats up when the water rises. The second enlarged diameter section 3 generates an oil-water mixture to lift the hollow silica sphere 4. Then, the oil continues to rise upward on the side of the hollow silica sphere 4, and the hollow silica sphere 4 rises simultaneously with the water surface. When it reaches the top of the first enlarged diameter section 2, it blocks the inlet at the lower end of the outlet pipe 12 and seals the water in the activity chamber.

[0029] The other end of the outlet pipe 12 (i.e., the end far from the first enlarged diameter section 2) is connected to a connecting pipe 13. The connecting pipe 13, the outlet pipe 12, and the inhalation pipe 6 are connected in sequence from top to bottom to form an oil pumping pipeline.

[0030] Refer to Figures 1-4 , A wind shield 10 is fixedly connected to the upper surface of the inlet disk 8, and a buoyancy ball 11 is fixedly connected to the lower surface of the inlet disk 8. The wind shield 10 rotates the inlet disk 8 when there is wind on the water surface. The adjustment of the buoyancy ball 11 and the main buoyancy ball 19 ensures that the inlet disk 8 is always in the water surface position. Driven by the wind force and the wind shield 10, the inlet disk 8 rotates. The floating oil enters the central hole 24 from the suction inlet 9 on the upper surface of the inlet disk 8, then enters the activity chamber from the lower end of the inhalation pipe 6, and then enters the connecting pipe 13 through the outlet pipe 12.

[0031] Refer to Figures 1-4 , A stabilizing rod 14 is fixedly connected to the upper surface of the support plate 1, and a support inner frame 15 is fixedly connected to the upper end of the stabilizing rod 14.

[0032] The stabilizing rod 14 and the supporting inner frame 15 provide stable support for the equipment, making it convenient to place a negative pressure pump or other useful equipment.

[0033] Reference Figures 1-4 A fixing block 21 is fixedly connected to the position of the supporting inner frame 15 corresponding to the connecting pipe 13 for fixing the connecting pipe 13 .

[0034] Reference Figures 1-4 The supporting inner frame 15 is welded with the supporting outer frame 16 , and the supporting inner frame 15 is movably connected with the carrying box 22 .

[0035] The supporting outer frame 16 ensures the overall stability of the equipment, and a screen is placed outside to block large impurities such as branches and only extract floating oil.

[0036] Reference Figures 1-4 A plurality of connecting pieces 17 are fixedly connected to the upper surface of the supporting outer frame 16, and a main supporting rod 18 is welded to the bottom of the supporting outer frame 16. The connecting piece 17 can be adjusted or fixed in a corresponding position by threading a rope or hooking it from the outside. Figures 1-4 The main support rod 18 has a main buoy 19 fixedly connected to its lower surface, and a stabilizing sheet 20 fixedly connected to its outer surface. The main buoy 19 can float the entire device to the upper surface of the water, and the stabilizing sheet 20 can expand the overall support surface to ensure the stability of the device.

[0037] The principle of this embodiment is:

[0038] The whole equipment is placed at the position where floating oil needs to be extracted. The main float 19 floats the whole equipment to the upper part of the water surface. The stabilizing sheet 20 expands the overall supporting surface to ensure the stability of the equipment. At the same time, the connecting sheet 17 can be threaded with a rope or hooked from the outside to make various adjustments or fix the corresponding position. The supporting inner frame 15, the supporting outer frame 16, the main supporting rod 18, and the stabilizing rod 14 complete the support of the whole equipment. Under the action of wind force, the inlet disc 8 can rotate on the suction pipe 6, and the oil-water mixture on the water surface is sucked from the suction pipe 6. The port 9 is screwed into the central hole 24 and continues upward along the suction pipe 6. The hollow silicon ball 4 sinks to the bottom at the floating oil and floats when the water rises. After the oil-water mixture enters the second expansion section 3, the hollow silicon ball 4 is lifted up, and then the oil continues to move upward at the side of the hollow silicon ball 4, and the hollow silicon ball 4 rises with the water surface. When it reaches the upper end of the first expansion section 2, the oil extraction pipeline is cut off, and the water is sealed in the active chamber. As the floating oil continues to be lifted up, it finally falls into the cargo box 22, or is connected to a negative pressure pump at the outlet pipe 12 and extracted to the corresponding position.

[0039] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present application.
