Description

Technical Field

[0002] In water conservancy projects, in order to improve the efficiency of water conservancy projects and to ensure their safety, water conservancy drainage systems are usually used to control and guide the water flow in water conservancy projects to improve the operating efficiency of water conservancy projects. Existing water conservancy drainage systems are usually composed of water level collection modules, interception filters, control modules and drainage channels.

[0003] For example: the invention patent with application number CN202010623113.2 discloses a drainage device for water conservancy projects, which specifically includes a drainage channel and a diversion channel connected to the drainage channel; the drainage channel is provided with a water inlet and a water outlet, the diversion channel is located between the water inlet and the water outlet, and the drainage channel is provided with a flow limiting gate between the diversion channel and the water outlet, the flow limiting gate moves in a vertical direction and can enter the drainage channel to limit part of the water flow through the outlet; the diversion channel is provided with a diversion outlet, and the connection between the drainage channel and the diversion channel is rotatably connected with a diversion gate capable of closing the connection between the drainage channel and the diversion channel; the drainage channel is provided with a driving mechanism for controlling the up and down movement of the flow limiting gate, and the driving mechanism simultaneously drives the diversion gate to rotate; the present invention can divert the water passing through the drainage channel to the diversion channel and discharge it elsewhere when the water flow passing through the drainage channel is too large, so as to prevent all the water flow from flowing from the drainage channel to the tributary, causing the tributary to be overloaded and burst.

[0004] However, in order to ensure smooth drainage and pure water quality, staff usually use interception filters to intercept debris in the water during drainage. With long-term use, a large amount of debris will gradually accumulate at the interception filter. In order to prevent the accumulated debris from clogging the interception filter, staff are usually required to regularly clean up the garbage intercepted at the interception filter. However, as time goes by, the amount of debris accumulated at the interception filter will be quite large, which makes the workload required for cleaning larger, the labor intensity of the staff higher, and the use is more inconvenient. Summary of the invention

[0005] In view of this, the present invention provides a water conservancy drainage system and a drainage method, which have a salvage frame that can automatically salvage and clean up intercepted debris during the drainage process. During the drainage process, the flowing water will impact the driving water wheel to rotate, and the driving water wheel will drive the transmission shaft to rotate during the rotation of the transmission shaft.

The control shaft is driven to rotate through the rotation of the second bevel gear, and then a series of transmissions are used to drive the reciprocating screw to rotate. During the rotation of the reciprocating screw, the lifting slide will be driven to lift and reciprocate. During the reciprocating lifting of the lifting slide, the salvage frame will be driven to lift and reciprocate. During the lifting of the salvage frame, the debris blocked by the filter screen will be salvaged.

At this time, the water in the water conservancy project will enter the drainage channel 5 through the water inlet 501 and be discharged from the water outlet 502 through the drainage of the drainage channel 5. The setting of the interception filter 505 is used to block the debris in the drainage process to prevent the debris in the water from clogging or damaging the equipment in the subsequent drainage system. In the process of drainage, the flowing water will impact the driving water wheel 507 to rotate the driving water wheel 507. In the process of rotating the transmission shaft 506, the first bevel gear 508 is driven to rotate. In the process of rotating the first bevel gear 508, the second bevel gear 511 meshing therewith is driven to rotate. The rotation of the second bevel gear 511 drives the control shaft 510 to rotate. In the process of rotating the control shaft 510, the first pulley 512 is driven to rotate. In the process of rotating the first pulley 512, the second pulley 514 is rotated through the transmission belt. In the process of rotating the second pulley 514, the reciprocating screw 513 is driven to rotate. In the process of rotating the reciprocating screw 513, the lifting slide 515 is driven to reciprocate and lift. During the reciprocating lifting process, the salvage frame 516 will be driven to lift and lower back and forth. During the lifting process of the salvage frame 516, the debris that is blocked by the interception filter 505 will be salvaged. During the rising process of the salvage frame 516, the control gear 518 will slowly contact the control rack 526, and the control rack 526 will drive the control gear 518 to rotate. The rotation of the control gear 518 drives the salvage frame 516 to flip over, and the salvaged garbage is poured out of the drainage channel 5. During the descent of the salvage frame 516, the control rack 526 will drive the control gear 518 to rotate in the opposite direction, so that the salvage frame 516 is reset. Through the self-locking characteristics between the first ratchet 523 and the first pawl 522, the salvage frame 516 is locked on the lifting slide 515. During the lifting process, the first transmission gear 524 does not drive the transmission worm 520 to rotate, while during the descent of the lifting slide 515, the first transmission rack 525 drives the first transmission gear 524 to rotate, and during the rotation of the first transmission gear 524, the transmission worm 520 is driven to rotate, and during the rotation of the transmission worm 520, the transmission worm wheel 519 is driven to rotate, and the rotation of the transmission worm wheel 519 drives the rotating seat 517 to rotate, and the rotation of the rotating seat 517 drives the salvage frame 516 to flip over and stand up the salvage frame 516 to prevent the salvage frame 516 from pressing down the obstructing debris during the descent process, and then through the self-locking characteristics between the second pawl 527 and the second ratchet 528,When the lifting carriage 515 is ascending, the second transmission gear 529 will not drive the transmission worm 520 to rotate. After the lifting carriage 515 descends a certain distance, the second transmission rack 530 will drive the second transmission gear 529 to rotate. During the rotation of the second transmission gear 529, the transmission worm 520 will be driven to rotate in the opposite direction, and the transmission worm wheel 519 will be driven to rotate in the opposite direction, so that the rotating seat 517 drives the salvage frame 516 to flip and reset to salvage the debris again. At the same time, during the flipping and resetting of the salvage frame 516, the debris such as stones deposited in the lower part of the drainage channel 5 can also be salvaged.

[0050] Specific usage and function of this embodiment: In the present invention, when the water level information collected by the water level acquisition module 1 is too high, the data control terminal 2 will start the second control motor 602 through the feedback control module 3, so that the second control motor 602 drives the diversion baffle 603 to rotate. At this time, the water in the drainage channel 5 will be diverted into the diversion channel 6 and flow out through the diversion hole 601, thereby accelerating the efficiency of water drainage.

8. A drainage method for a hydraulic drainage system as claimed in claim 1, characterized in that:

01. The water level information in the water conservancy project is collected through the water level acquisition module and transmitted to the data control terminal for identification and monitoring. When the water level in the water conservancy project is too high, the data control terminal transmits the instruction to the feedback control module, and the feedback control module generates a control instruction and transmits it to the drainage network; 02. After receiving the control command, the drainage network will start the first control motor to open the drainage baffle, drain the water in the water conservancy project through the drainage channel, and block the debris in the water through the interception filter in the drainage channel to ensure the cleanliness of the water quality and facilitate the subsequent use of the drained water; 03. During the diversion process, the water flow will impact the driving water wheel, causing the driving water wheel to rotate, and in the process of driving the water wheel to rotate, the transmission shaft will be driven to rotate, and in the process of the transmission shaft rotating, the first bevel gear will be driven to rotate, and in the process of the first bevel gear rotating, the second bevel gear meshing with it will be driven to rotate, and the control shaft will be driven to rotate through the rotation of the second bevel gear, and in the process of the control shaft rotating, the first pulley will be driven to rotate, and in the process of the first pulley rotating, the second pulley will be driven to rotate through the transmission belt, and in the process of the second pulley rotating, the reciprocating screw will be driven to rotate, and in the process of the reciprocating screw rotating, the lifting slide will be driven to reciprocate, and in the process of the lifting slide reciprocating, the salvage frame will be driven to reciprocate, and in the process of the salvage frame lifting, the debris blocked by the interception filter will be salvaged; 04. During the rising process of the salvage frame, the control gear will slowly contact the control rack, and the control rack will drive the control gear to rotate. The rotation of the control gear will drive the salvage frame to flip over, and the salvaged garbage will be poured out of the drainage channel. During the descent of the salvage frame, the control rack will drive the control gear to rotate in the opposite direction, so that the salvage frame can be reset; 05. During the descent of the lifting slide, the first transmission rack drives the first transmission gear to rotate, which in turn drives the transmission worm to rotate, which in turn drives the transmission worm wheel to rotate, which in turn drives the rotating seat to rotate, which in turn drives the salvage frame to flip over and stand up, preventing the salvage frame from pressing down the obstructing debris during the descent; 06. After the lifting slide descends a certain distance, the second transmission rack will drive the second transmission gear to rotate. During the rotation of the second transmission gear, the transmission worm will be driven to rotate in the opposite direction, and the transmission worm wheel will be driven to rotate in the opposite direction, so that the rotating seat drives the salvage frame to flip and reset to salvage the debris again. At the same time, during the process of flipping and resetting the salvage frame, the debris deposited in the lower part of the drainage channel can also be picked up; 07. When the water level information collected by the water level acquisition module is too high, the data control terminal will start the second control motor through the feedback control module, so that the second control motor drives the diversion baffle to rotate. At this time, the water in the drainage channel will be diverted into the diversion channel and flow out through the diversion hole, thereby accelerating the efficiency of water drainage.
