[0015] The following is a specific embodiment of the utility model, and the technical scheme of the utility model is further described in combination with the drawings, but the utility model is not limited to these embodiments.
[0016] As Figs. 1-2 , the utility model provides a kind of tailings treatment backwater micro water energy power generation device, including blocking wall 1 and the backwater outlet 2 integrated with blocking wall 1, the backwater outlet 2 is connected with one end of water diversion groove 6, water diversion groove 6 other end inclined downward extends and is connected with the water inlet of power generation equipment, for guiding backwater in tailings pond to power generation equipment, the power generation equipment includes water turbine 12, water turbine 12 is installed on the main shaft of generator 11 and is located inside casing 7, casing 7 one side is provided with the water inlet connected with water diversion groove 6, and the spray head 10 for cleaning water turbine 12 is fixedly connected on the side wall of casing 7.
[0017] The blocking wall 1 and the backwater inlet 2 are integrally formed by pouring high-strength concrete. The blocking wall 1 is vertically arranged between the tailings pond and the water diversion channel 6. The backwater inlet 2 is at the bottom of the blocking wall 1 and is in sealing connection with the backwater pipeline of the tailings pond through a flange. The water diversion channel 6 is welded by corrosion-resistant stainless steel plates. One end of the water diversion channel 6 is welded with the backwater inlet 2, and the other end extends downward at an angle of 15°-30°. The inner wall is polished to reduce water resistance. In the power generation equipment, the runner of the axial flow water turbine 12 is precisely cast by high-strength alloy. The special curved blades are connected to the main shaft of the generator 11 through a key. The whole is arranged in the square welded casing 7. The water inlet on one side of the casing 7 is connected with the water diversion channel 6. The side wall is fixedly connected with the spray head 10. When the water turbine 12 operates, the backwater flows into the water diversion channel 6 to drive the runner to rotate the main shaft of the generator 11 to generate electricity. When cleaning is needed, the external water source is used to spray the spray head 10 to wash the water turbine 12. The device is organically combined to realize the effective utilization of backwater micro water energy and the stable operation of the power generation equipment.
[0018] The backwater inlet 2 is provided with a water opening mechanism. The water opening mechanism comprises a U-shaped groove 3 arranged in the backwater inlet 2. The U-shaped groove 3 is provided with a main baffle 5 which can slide up and down to control the water flow into the water diversion channel 6.
[0019] The water opening mechanism arranged at the backwater inlet 2 is composed of the U-shaped groove 3 embedded in the backwater inlet 2 and the movable main baffle 5. The U-shaped groove 3 is integrally formed by wear-resistant and corrosion-resistant alloy material and is tightly embedded in the inner wall of the backwater inlet 2. The main baffle 5 is also made of alloy material and is adapted to the shape of the U-shaped groove 3 to ensure stable up-and-down sliding in the U-shaped groove 3. When it is necessary to adjust the water flow into the water diversion channel 6, the main baffle 5 is driven to move up and down in the U-shaped groove 3. When the main baffle 5 rises, the water area of the backwater inlet 2 is increased, and more backwater flows into the water diversion channel 6. When the main baffle 5 descends, the water area is reduced, and the water flow is limited, so as to realize flexible and accurate control of the water flow into the water diversion channel 6 to adapt to the operation requirements of the power generation equipment under different working conditions.
[0020] The U-shaped groove 3 is fixedly connected with an inverted U-shaped groove. The inverted U-shaped groove is provided with a cylinder 4. The push rod of the cylinder 4 is fixedly connected with the main baffle 5 to drive the main baffle 5 to slide up and down in the U-shaped groove 3 and the inverted U-shaped groove.
[0021] A reverse U-shaped groove is tightly fixed above the U-shaped groove 3, and a driving cylinder 4 is installed inside the reverse U-shaped groove. The cylinder 4 is fixed on the top of the reverse U-shaped groove by bolts, and its push rod extends vertically downward and is rigidly connected with the top of the main baffle 5, ensuring the stability and reliability of power transmission. When it is necessary to adjust the water flow entering the water guide groove 6, the control signal drives the cylinder 4 to work, and the push rod of the cylinder 4 extends or retracts according to the instruction, directly driving the main baffle 5 to slide accurately in the vertical direction in the U-shaped groove 3. When the push rod extends, it pushes the main baffle 5 to slide downward, reducing the water passing area of the backwater inlet 2, thereby limiting the water flow; when the push rod retracts, it pulls the main baffle 5 to slide upward, increasing the water passing area of the backwater inlet 2, and less backwater of tailings treatment can flow into the water guide groove 6. Through the linkage of the cylinder 4 and the main baffle 5, accurate control of the opening of the backwater inlet 2 is realized, and the water flow entering the water guide groove 6 is flexibly adjusted to meet the operation requirements of the power generation equipment under different working conditions, and the power generation device works efficiently and stably.
[0022] The inner side walls of the U-shaped groove 3 and the reverse U-shaped groove are provided with sliding grooves, and the two sides of the main baffle 5 are correspondingly embedded in the sliding grooves to realize stable upward and downward sliding of the main baffle 5 in the U-shaped groove 3 and the reverse U-shaped groove.
[0023] The inner side walls of the U-shaped groove 3 and the reverse U-shaped groove are provided with sliding grooves, and the two sides of the main baffle 5 are correspondingly embedded in the sliding grooves to realize stable upward and downward sliding of the main baffle 5 in the U-shaped groove 3 and the reverse U-shaped groove.
[0024] One of the side walls of the inclined downward extending end of the other end of the water guide groove 6 is a movable wall 8, which is hinged with the connecting rod of the electric push rod 9 and is used to control the size of the opening connecting the water guide groove 6 with the water inlet of the power generation equipment.
[0025] The water diversion tank 6 extends obliquely downward to an end connected with the water inlet of the power generation device, and one side wall surface thereof is designed to be movable, and the movable wall surface 8 is connected with the remaining fixed wall surface of the water diversion tank 6 through a hinge, so that the movable wall surface 8 is stable and flexible. The edge of the wall surface is provided with a sealing rubber strip, which can effectively prevent water leakage when the movable wall surface 8 is attached to the other wall surfaces of the water diversion tank 6. An electric push rod 9 driving device is installed outside the movable wall surface 8, one end of the electric push rod 9 is fixed to the external support of the water diversion tank 6, and the connecting rod is hinged to the movable wall surface 8. When it is necessary to adjust the water flow entering the power generation device, the electric push rod 9 is controlled to extend or retract through the control system, so as to push or pull the movable wall surface 8 to rotate around the hinge, and then the size of the opening of the water diversion tank 6 connected with the water inlet of the power generation device is changed. When the opening is increased, more water flow enters the power generation device to increase the power generation capacity; when the opening is reduced, the water flow entering the device is limited, so as to facilitate the maintenance of the device or reduce the energy consumption when the power generation demand is low, so as to accurately control the water flow and ensure the efficient and stable operation of the power generation device.
[0026] The use process of the tailings treatment backwater micro water energy power generation device is as follows: the tailings treatment backwater first passes through the blocking wall 1 and then enters the water diversion tank 6 through the backwater outlet 2, the opening mechanism of the backwater outlet 2 plays a role, the push rod of the air cylinder 4 drives the main baffle 5 to slide in the U-shaped groove 3, so as to adjust the water flow entering the water diversion tank 6; the water diversion tank 6 extends obliquely downward, and the gravity is used to accelerate the water flow, and the movable wall surface 8 of the water diversion tank 6 is flexibly controlled under the action of the electric push rod 9, so as to accurately control the size of the opening of the water inlet of the power generation device. After the water flow enters the power generation device, the runner of the water turbine 12 is rotated, and the main shaft of the generator 11 is driven to generate electricity. During the operation process, if it is necessary to clean the water turbine 12, the spray head 10 on the side wall of the machine shell 7 is opened to spray water for cleaning. The whole process realizes the effective utilization of tailings treatment backwater micro water energy, and realizes the stable operation and convenient maintenance of the power generation device.
