Description

Technical Field

[0001] The invention relates to the technical field of water conservancy projects, in particular to a water conservancy spillway gate floating push drain. Background Art

[0002] In the field of water conservancy projects, some small gates are mostly manually operated, which makes them unable to open and release floodwaters in time when water levels rise rapidly. Some spillway control gates, on the other hand, use floating push devices to control the gate opening and closing. However, the buoyancy of conventional floating push devices is usually not adjustable, making it difficult to adapt to different needs during different periods. For example, during the flood season, when rainfall is prone to surge, this cannot meet the diverse discharge needs. Therefore, it is necessary to develop a floating push discharger for water conservancy spillway gates. Summary of the Invention

The gate opening and closing mechanism 400 is arranged at the end of the resistance arm 204 away from the fulcrum 201, and includes a steel wire rope 401 fixed to the end of the adjustment arm 206. The steel wire rope 401 is suspended with a gate body 403 after passing through a fixed pulley 402. The gate body 403 is used to block / dredge the river water in the spillway 103.

[0023] Example 2: Based on Example 1, a filter screen 105 is fixedly installed on the inner side of the communication port 104, and a cleaning mechanism for cleaning the filter screen 105 is provided on the side wall of the dam 100. The filter screen 105 can properly filter the river water flowing into the spillway 103, and the cleaning mechanism can properly prevent the filter screen 105 from being clogged by impurities in the mesh, thereby affecting the flow of the river water. The cleaning mechanism includes a side plate 106 fixed on the side wall of the dam 100 near the communication port 104, and the side plates 106 are provided with four in total and are respectively located on the upper and lower sides of the communication port 104. A limiting slide 107 is fixedly provided between the two side plates 106 below the communication port 104, and the limiting slide 107 is arranged along the length direction of the filter screen 105. A reciprocating screw 108 parallel to the limiting slide 107 is provided between the two side plates 106 above the communication port 104 through a bearing sleeve. A cleaning plate 109 is slidably provided on the rod body of the limiting slide 107, and the rod body of the limiting slide 107 slides through the cleaning plate 1 09, a cleaning bar 110 for cleaning the filter 105 is provided on one side of the cleaning plate 109 close to the filter 105, the rod body of the reciprocating screw 108 movably penetrates the upper end of the cleaning plate 109, and the rotating reciprocating screw 108 drives the cleaning plate 109 to reciprocate along the rod body of the limiting slide 107, and a driving mechanism for driving the reciprocating screw 108 to rotate is provided on the dam 100; when the reciprocating screw 108 rotates, it drives the cleaning plate 109 to reciprocate along the length direction of the filter 105, thereby reciprocatingly cleaning the filter 105 through the cleaning bar 110, thereby reducing the occurrence of the filter 105 being clogged by impurities; The lengths of the reciprocating screw rod 108 and the limiting slide rod 107 are not less than the length of the filter 105, the length of the cleaning plate 109 is not less than the width of the communication port 104, and the area covered by the reciprocating movement of the cleaning bar 110 is not less than the entire area of ​​the filter 105; thus, the cleaning bar 110 can clean the filter 105 more comprehensively. The driving mechanism includes a supporting plate 111 fixed on the side wall of the dam 100 near the end position of the reciprocating screw 108, and a vertical rotating rod 112 is rotatably provided on the supporting plate 111 through a bearing. The rotating rod 112 and the reciprocating screw 108 are arranged vertically, and the reciprocating screw 108 is fixedly provided with a first bevel gear 113 at one end near the rotating rod 112, and a second bevel gear 114 is fixedly provided on the rod body of the rotating rod 112, which meshes with the first bevel gear 113, and a fan blade 115 is fixedly provided at an equal angle around the upper end of the rotating rod 112; in this embodiment, wind energy is used to drive the rotating rod 112 to rotate. When the wind blows the fan blade 115 to rotate, the rotating rod 112 drives the reciprocating screw 108 to rotate through the second bevel gear 114 and the first bevel gear 113, thereby realizing the cleaning of the filter screen 105. Other ways of driving the reciprocating screw 108 to rotate can also be used.

[0024] The lever 204 is rotated to move the adjusting arm 206 in the direction of rotation, and the lever 204 is rotated to move the adjusting arm 206 in the direction of rotation. A reinforcement plate 210 is fixedly arranged on the spillway 102, the bottom of the fulcrum 201 is fixed on the top wall of the reinforcement plate 210, and a "triangular" reinforcement frame 211 is fixedly arranged between the bottom of the reinforcement plate 210 and the side wall of the spillway 102; the reinforcement frame 211 can improve the stability of the reinforcement plate 210 and the supporting capacity of the fulcrum 201.

[0025] The control mechanism includes a mounting frame 305 rotatably arranged at the bottom of one end of the power arm 203 away from the fulcrum 201, the mounting frame 305 is in the shape of a "mouth", and a vertical waterproof motor 306 is fixedly arranged on the top wall of the inner cavity of the mounting frame 305, and the output shaft of the waterproof motor 306 is connected to a vertical threaded column 307 through a coupling, and the rod body of the threaded column 307 rotates through the bottom wall of the mounting frame 305 through a bearing, and the lower end of the threaded column 307 is rotatably mounted on the top wall center of the main floating plate 302 through a bearing seat, and an annular lifting block 308 is threadedly sleeved on the rod body of the threaded column 307, and a linkage rod 309 is hingedly arranged on the top of each auxiliary floating plate 304, and four linkage rods 309 are arranged around the lifting block 308 at equal angles, and the other end of the linkage rod 309 is hingedly arranged on the outer wall of the lifting block 308. The four guide posts 310 are arranged around the lifting block 308 at equal intervals and are spaced apart from the linkage rod 309. The outer wall of the lifting block 308 is provided with guide blocks 311 at equal intervals. The four guide posts 310 slide vertically through the upper and lower walls of the four guide blocks 311 respectively. When the waterproof motor 306 drives the threaded post 307 to rotate, the lifting block 308 is restricted by the four guide posts 310 and the four guide blocks 311. The lifting block 308 cannot rotate and can only move up and down in the vertical direction, thereby pushing and pulling the auxiliary floating plate 304 through the linkage rod 309 to change the angle between the auxiliary floating plate 304 and the main floating plate 302. The four guide posts 310 are arranged around the lifting block 308 at equal intervals, which can also make the lifting block 308 have equal force on all sides, making its lifting movement more stable. Among them, when the lifting block 308 is at the lowest point of the threaded column 307, the bottom surfaces of the four auxiliary floating plates 304 are arranged coplanar with the bottom surface of the main floating plate 302; because during the flood season, rainwater is likely to increase suddenly and the water level is likely to rise sharply, the area of ​​the bottom of the floating push plate 301 that contacts the river water is designed to be adjustable. During the flood season, the four auxiliary floating plates 304 can be "lowered" in advance, so that the floating push plate 301 is unfolded into a flat shape, thereby increasing the buoyancy effect area of ​​the floating push plate 301 as a whole; and under normal circumstances, when the water level is stable, the four auxiliary floating plates 304 can be "folded" so that the floating push plate 301 as a whole shrinks into a compact structure, reducing the impact of water flow impact on the floating push plate 301 as a whole, which is conducive to the long-term use of the floating push plate 301 as a whole; The upper end of the threaded column 307 is located inside the mounting frame 305 where an annular support plate 312 is fixedly provided. The bottom of the support plate 312 is evenly spaced and fixed with support wheels 313. The rollers of the support wheels 313 roll on the inner bottom wall of the mounting frame 305. When the threaded column 307 rotates, the rollers of the support wheels 313 roll synchronously on the inner bottom wall of the mounting frame 305, which properly stabilizes the threaded column 307 and does not hinder the rotation of the threaded column 307.

[0026] Example 5: Based on Example 1, a dam body 404 is fixedly provided on the side of the spillway 103 away from the communication port 104. A drain port 405 is opened on the side wall of the dam body 404. A door frame 406 is installed inside the drain port 405. The door body 403 slides vertically in the door frame 406 to block / open the drain port 405. A vertical pull rod 407 is fixedly provided at the top center of the door body 403. The rod body of the pull rod 407 is connected to the drain port 405 by a linear bearing. The top of the pull rod 407 slides through the top wall of the door frame 406, and the top end of the pull rod 407 is fixedly connected to the other end of the wire rope 401; when the floating push plate 301 gradually rises, it drives the power arm 203 to rise and the resistance arm 204 to fall, and then the door body 403 is pulled up by the wire rope 401 to open the drain port 405 to discharge the river water in the spillway 103. When the water level gradually drops, the floating push plate 301 drops, and the door body 403 drops and closes accordingly, thereby stopping the river water discharge; A fixing frame 408 is fixedly installed on the spillway 102. The fixing frame 408 is located between the door frame 406 and the lever mechanism 200. A mounting frame 409 is fixedly installed on the top of the fixing frame 408. The fixed pulley 402 is rotatably arranged on the inner side of the mounting frame 409 via a bearing. The steel wire rope 401 fits and passes through the upper surface of the fixed pulley 402. A lifting frame 410 is provided above the fixed frame 408 via a lifting mechanism. A tensioning pulley 411 is provided on the inner side of the lifting frame 410 via a bearing. The steel wire rope 401 fits and passes through the upper surface of the tensioning pulley 411. When the position of the adjusting arm 206 changes, the tightness of the steel wire rope 401 and the fixed pulley 402 also changes. Therefore, by adjusting the height of the tensioning pulley 411, the tension of the steel wire rope 401 is changed, ensuring that the lifting and lowering of the door body 403 can be controlled when the floating push plate 301 is raised or lowered. The lifting mechanism includes a vertical electric telescopic rod 412 fixed to the top of the fixed frame 408, the output shaft of the electric telescopic rod 412 moves in the vertical direction, and the output shaft of the electric telescopic rod 412 is fixed to the bottom of the lifting frame 410. The top of the fixed frame 408 is located on both sides of the electric telescopic rod 412 and the lifting frame 410, and vertical auxiliary frames 413 are symmetrically provided. The side walls of the auxiliary frames 413 are opened with lifting grooves 414, and vertical auxiliary rods 415 are fixedly installed on the inner sides of the lifting grooves 414. Auxiliary blocks 416 located in the lifting grooves 414 are protruding on both sides of the lifting frame 410. The rod bodies of the two auxiliary rods 415 slide through the upper and lower walls of the two auxiliary blocks 416 respectively; by starting the electric telescopic rod 412, the height of its own output shaft can be adjusted, thereby controlling the lifting of the lifting frame 410, and the auxiliary blocks 416 then slide vertically along the rod bodies of the auxiliary rods 415, which can improve the stability of the lifting frame 410 after lifting.

[0027] During use, water is automatically discharged when the water level rises: when the river water level rises, the floating push plate 301 gradually rises due to the buoyancy; the floating push plate 301 is connected to the power arm 203, driving the power arm 203 to rise. According to the principle of leverage, the rising power arm 203 causes the resistance arm 204 to fall; the wire rope 401 connected to the end of the resistance arm 204 is connected to the gate body 403 through the fixed pulley 402. The resistance arm 204 falls, pulling the wire rope 401, and then the gate body 403 rises, opening the water discharge port 405 on the side wall of the dam body 404, and the river water in the spillway 103 is discharged; Closing the drain port when the water level drops: As the water level gradually drops, the buoyancy of the floating push plate 301 decreases, the floating push plate 301 drops, the power arm 203 drops accordingly, the resistance arm 204 rises, the wire rope 401 relaxes, and the door body 403 drops under its own gravity, closing the drain port 405 and stopping the discharge of river water; Adjust the buoyancy area of ​​the floating push plate: During the flood season, the amount of rain increases and the water level may rise sharply. At this time, the waterproof motor 306 is started; the waterproof motor 306 drives the threaded column 307 to rotate. Since the lifting block 308 is restricted by the guide column 310 and the guide block 311 and cannot rotate, it can only be lifted and lowered in the vertical direction; the lifting block 308 descends and pushes the auxiliary floating plate 304 outward through the linkage rod 309, so that the angle between the auxiliary floating plate 304 and the main floating plate 302 becomes larger, and the floating push plate 301 is unfolded into a flat shape, increasing the contact area with the river surface and increasing the buoyancy to adapt to high water levels; when the water level is stable, the waterproof motor 306 is started in the reverse direction to make the lifting block 308 rise, and the auxiliary floating plate 304 is retracted inward through the linkage rod 309, reducing the impact of water flow on the floating push plate 301, which is beneficial to the long-term use of the floating push plate 301; Cleaning the filter screen at the connecting port: The wind blows the fan blades 115 to rotate, which in turn drives the rotating rod 112 to rotate. The second bevel gear 114 on the rotating rod 112 engages with the first bevel gear 113 on the reciprocating screw 108, thereby rotating the reciprocating screw 108. The rotation of the reciprocating screw 108 drives the cleaning plate 109 to reciprocate along the limiting slide bar 107. The cleaning strips 110 on the cleaning plate 109 clean the filter screen 105 inside the connecting port 104 to prevent the filter screen 105 from being blocked by impurities, thereby ensuring the normal flow of river water. Adjust the length of the lever resistance arm: according to actual needs, turn the knob 209, which drives the threaded rod 207 to rotate. Under the action of the threaded rod 207 and the guide rod 208, the adjustment arm 206 slides along the slide groove 205, changing the length of the resistance arm 204, thereby adjusting the length ratio of the resistance arm 204 and the power arm 203 of the lever to meet the minimum buoyancy requirements for opening and closing the door body 403 under different conditions; Adjusting the tension of the wire rope: When the position of the adjusting arm 206 changes and the tightness of the wire rope 401 and the fixed pulley 402 changes, the electric telescopic rod 412 is started; the output shaft of the electric telescopic rod 412 is extended and retracted, driving the lifting frame 410 to move up and down, and the tensioning wheel 411 on the lifting frame 410 moves up and down accordingly, thereby adjusting the tension of the wire rope 411 to ensure that the lifting and lowering of the door body 403 can be stably controlled when the floating push plate 301 is raised and lowered.
