Most of these oil leaks are concentrated in the collecting well of the water conservancy and hydropower station, posing a potential threat to water quality safety. To ensure environmental safety and prevent oil pollution from being discharged into the downstream river, manual regular cleaning is usually used to handle oil pollution in the collecting well, but this method has many drawbacks.

[0023] The utility model will be explained in detail below in combination with the drawings and embodiment.

[0024] Embodiment: in order to solve the problem of oil pollution cleaning of water collecting well, guarantee downstream water quality safety, urgently need to explore a kind of efficient safe and environmental new oil pollution cleaning method, realize the effective treatment of oil pollution of water collecting well, improve oil pollution cleaning efficiency, reduce the risk of manual operation, reduce the burden of manual operation.

[0025] Therefore, a kind of blowing assembly for oil surface is conceived, which can effectively clean oil pollution with less manpower input, meet environmental protection requirements, reduce the potential risk of downhole operation, and ensure the safety of operating personnel.

[0026] As Figure 1As shown, the air blowing assembly comprises a gas supply pipeline 10, one end of the gas supply pipeline 10 is connected with a gas source, and the other end of the gas supply pipeline 10 is provided with an air blowing section 13 arranged on the water surface for blowing the oil stains on the water surface, and the air blowing section 13 is provided with an air blowing port 14 in communication with the gas supply pipeline 10.

[0027] According to common sense, oil and water are incompatible, and the same volume of oil is much lighter than water, that is, under the same conditions, the density of oil is less than that of water, so oil always floats on the water surface. The conception of the utility model is to first arrange an air blowing assembly on the water surface, and arrange the air blowing section 13 at the shore, because the oil is floating on the water surface, so by controlling the gas supply of the gas supply pipeline 10, the air blowing port 14 blows air to the water surface, and the oil stains floating on the water surface of the water collecting well are blown into the oil collecting tank 30 on the opposite side for centralized treatment. In this way, the time for entering the water collecting well for operation can be reduced, and the safety risk of operation is greatly reduced.

[0028] In order to keep the air blowing section 13 on the water surface at all times, in one embodiment, the air blowing assembly further comprises a carrier 20, and the air blowing section 13 is arranged on the carrier 20 and kept on the water surface by the carrier 20.

[0029] Specifically, the carrier 20 can keep the air blowing section 13 on the water surface by at least the following two different ways,

[0030] One of them is that the carrier 20 is slidably connected with the shore of the water body, and a locking member for locking the height of the carrier 20 is arranged between the carrier 20 and the shore of the water body. The carrier 20 can be a plate-shaped structure, and the side close to the shore can be a sliding block matched with a sliding groove of the shore, and then a locking bolt is arranged on the sliding block, when the air blowing section 13 is just located on the water surface by adjusting to the appropriate height, the locking bolt is tightened, and the sliding block is fixed in the sliding groove.

[0031] The other is that the carrier 20 is a floating raft, and the air blowing section 13 is arranged at a suitable position on the floating raft, and the floating raft supports the air blowing section 13, so that the air blowing section 13 is just located on the water surface.

[0032] It should be noted that the water level will change, therefore, the gas supply pipeline 10 can be divided into three sections, such as Figure 2 As shown, they are a gas supply section 11 connected with the gas source, an intermediate section 12 connected with the gas supply section 11 and the air blowing section 13, and the air blowing section 13, and the intermediate section 12 can adopt the form of a hose to adapt to the height change of the air blowing section 13 caused by the height change of the water surface.

[0033] Generally speaking, the air pressure required by the air blowing assembly does not necessarily match the air pressure of the gas source completely, in order to obtain the required air pressure, the utility model also provides an oil blowing device for the oil surface, which comprises any one of the air blowing assemblies described above, such as Figure 2As shown, the gas supply pipeline 10 is provided with a valve group 15 for pressure regulation at one end connected to the gas source.

[0034] Specifically, in one embodiment, the control valve group 15 includes a mechanical valve 16 and a remote control valve 17, which can be located in the aforementioned air supply section 11, with the mechanical valve 16 located on the side of the remote control valve 17 closer to the air source.

[0035] Before cleaning the oil sludge in the sump, open the mechanical valve 16. Once the required air pressure is reached, close the mechanical valve 16 to stop the air supply. When cleaning the oil sludge, open the remote control valve 17 to release air pressure to the water surface, thus cleaning the oil sludge. Of course, to monitor the air pressure, a pressure gauge can be installed between the mechanical valve 16 and the remote control valve 17 on the air supply section 11.

[0036] The air purging pipe simply uses air pressure to move the oil slick to the other side. To ensure that the oil slick on the water surface enters the oil collection tank 30 and does not flow back into the water collection well, such as... Figure 3 As shown, the oil inlet 31 of the oil collection tank 30 can be set in an arc shape, which allows the blown floating oil to enter the oil collection tank 30 more easily. Then, a labyrinth component 32 is set after the oil inlet 31 to prevent the incoming oil from flowing back. This ensures that the oil collected in the oil collection tank 30 only enters and does not exit. The combined structure of the oil blowing device and the oil collection tank 30 is as follows. Figure 4 As shown.

[0037] To test the effectiveness of the oil blowing device and the oil collection tank 30 in cleaning oil from the water collection well, foam boards were selected to simulate the water collection well and the oil collection tank 30, and the oil blowing device was used to blow oil into the oil collection tank 30 for the experiment.

[0038] During the experiment, it was found that if the air pressure introduced by the oil blowing device was too high, water would splash on the surface, resulting in ineffective cleaning of the oil. However, if the air pressure introduced by the oil blowing device was too low, the oil could not be completely blown into the oil collection tank 30. In order to find the optimal air pressure value for cleaning oil, after repeated adjustments and multiple experiments, the optimal air pressure range of 0.1~0.15MPa was finally found. If the air pressure was higher than this, the water would splash too much, resulting in poor cleaning. If the air pressure was lower than this, the oil would not be cleaned thoroughly. Only within this air pressure range could the floating oil be completely blown into the oil collection tank 30, producing a significant cleaning effect.

[0039] After the oil was cleaned up, it was completely collected in the oil collection tank 30 on the right side. After two days of standing, the oil did not flow back into the water collection well. After a week of standing, the maze component 32 was effective, and all the oil was collected in the oil collection tank 30 without backflow.

[0040] The above-described embodiments only express the specific implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the present application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application.
