It is an important part of ensuring the normal operation of the hydropower station and environmental protection, and needs to be reasonably processed and controlled. By taking appropriate drainage management measures.

[0003] During the operation of a hydropower station, the lubricating oil in the mechanical equipment may leak, causing oil to enter the water that needs to be discharged. If the oil in the water is not cleaned, the pollutants will clog the pipes and equipment, causing drainage failures in the hydropower station. Direct discharge of sewage will also damage the environment. Utility Model Content

[0028] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0030] Embodiment 1, as Figure 1-Figure 6 As shown, the utility model provides a drainage structure of a runoff water diversion power station, comprising a main body mechanism 1, and an oil removal mechanism 2 is fixedly installed on one side of the outer wall of the main body mechanism 1;

[0031] The oil removal mechanism 2 includes a fixed plate 201, the outer wall of the fixed plate 201 is provided with four floats 202, the top of the fixed plate 201 is opened with a second hole 203, the inner wall of the second hole 203 is fixedly inserted with a water inlet pipe 204, the output end of the water inlet pipe 204 is fixedly connected to a water pump 205, the output end of the water pump 205 is fixedly connected to a water outlet pipe 206, the output end of the water outlet pipe 206 is fixedly connected to a treatment box 207, and the bottom of the water pump 205 is fixedly connected to the top of the treatment box 207, the output end of the treatment box 207 is fixedly connected to a water outlet valve 208, the output end of the treatment box 207 is fixedly connected to an oil outlet pipe 209, the output end of the oil outlet pipe 209 is fixedly connected to an oil storage tank 210, and one side of the outer wall of the treatment box 207 is fixedly connected to one side of the outer wall of the oil storage tank 210.

[0032] The effect achieved by the entire embodiment 1 is that the four floats 202 can drive the fixed plate 201 to float on the surface of the wastewater, so that the water inlet pipe 204 can contact the oil on the water surface, thereby increasing the oil removal effect and preventing the water inlet pipe 204 from entering the wastewater under the action of gravity and failing to remove the oil on the surface of the wastewater. At this time, the water pump 205 pumps the oil-water mixture into the treatment box 207 through the water inlet pipe 204. The density of the oil is relatively small and it will float on the water surface. At this time, the top oil will enter the oil storage tank 210 through the oil outlet pipe 209, and the bottom wastewater will be discharged through the water outlet valve 208, preventing the oil in the sewage from being directly discharged and damaging the environment. It can also prevent the oil from being blocked in the drainage system, damaging parts, and shortening the service life of the equipment.

[0033] Embodiment 2, as Figure 2-Figure 6 As shown, the main body mechanism 1 includes a water outlet channel 101, a first hole 102 is opened at the top of the water outlet channel 101, a group of first ear blocks 103 are fixedly installed on the inner surface wall of the water outlet channel 101, a group of first threaded holes 104 are opened on the outer wall of the group of first ear blocks 103, a group of first fixing screws 105 are rotatably connected to the inner surface wall of the group of first threaded holes 104, a grid 106 is rotatably connected between the outer walls of the group of first fixing screws 105, a group of second ear blocks 107 are fixedly installed on the inner surface wall of the water outlet channel 101, a group of second threaded holes 108 are opened on the outer wall of the group of second ear blocks 107, and a group of second threaded holes 108 are opened on the outer wall of the group of second threaded holes 108. A group of second fixing screws 109 are rotatably connected to the inner wall, and an oil removal plate 110 is rotatably connected between the outer walls of the group of second fixing screws 109. A fixing frame 111 is fixedly installed on the inner wall of the water outlet channel 101, and four springs 112 are fixedly installed on one side of the outer wall of the fixing frame 111. Dampers 113 are arranged inside the four springs 112, and a baffle 114 is fixedly installed between the outer walls of the four springs 112. The inner wall of the first hole 102 is fixedly inserted with the outer wall of the water inlet pipe 204, one side of the outer wall of the water outlet channel 101 is fixedly connected to one side of the outer wall of the treatment box 207, and one side of the outer wall of the water outlet channel 101 is connected to the oil storage tank 210.

[0034] The effect achieved by the entire embodiment 2 is that when wastewater is discharged into the outlet channel 101, it will impact on the baffle 114, and the four springs 112 and the damper 113 behind the baffle 114 will shrink to absorb the impact force, slowing down the scouring of the riverbed by high-speed drainage, and when the impact force weakens, the baffle 114 will be lifted up again, and then the wastewater flow rate will be weakened, and the rear grille 106 can block the pollutants inside the wastewater to prevent the pollutants from damaging the environment, and the rear degreasing plate 110 will further remove the oil and increase the degreasing effect. By rotating a set of first fixing screws 105 and a set of second fixing screws 109, the grille 106 and the degreasing plate 110 can be disassembled respectively to facilitate their cleaning or replacement, thereby avoiding the grille 106 and the degreasing plate 110 from losing the function of cleaning wastewater due to too long a time.

[0035] Working principle: When the power station discharges wastewater into the outlet channel 101, the high-speed wastewater will impact the baffle 114, driving the baffle 114 to move backward and squeeze the four springs 112 and damper 113 at the rear. The four springs 112 and damper 113 begin to shrink to absorb the impact force, and then the decelerated wastewater flows through the internal holes or the outside of the baffle 114. When the wastewater flows through the grille 106, the pollutants inside will block the pollutants in the wastewater. Then, the four floats 202 will always float on the water surface after contacting the wastewater, and make the water inlet pipe 204 contact the oil on the water surface through the fixed plate 201. At this time, the water pump 205 starts, and the oil is discharged through the water inlet pipe 206. 04 The oil-water mixture is extracted and brought to the treatment box 207 through the outlet pipe 206. At this time, the oil will float on the water surface and flow into the oil storage tank 210 through the outlet pipe 209 to be collected, and the waste water will be discharged through the outlet valve 208. The waste water in the outlet channel 101 will finally be filtered by the degreasing plate 110 to remove the remaining oil and then be discharged. When the structure needs to be cleaned or replaced after a period of use, it is only necessary to rotate a set of first fixing screws 105 and a set of second fixing screws 109 from the inside of a set of first ear blocks 103 and the second ear blocks 107 respectively, and then the grille 106 and the degreasing plate 110 can be removed.

[0036] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
