[0014] A method for using a gate opening and closing device with high water utilization safety, used to implement the above-mentioned gate opening and closing device with high water utilization safety, comprising: S1: First, weld the anchor assembly to the side of the U-shaped frame, then install the device in the middle of the canal or river channel, and pour concrete on both sides of the U-shaped frame, anchor the anchor assembly to the concrete, and complete the fixation of the device after the concrete solidifies. When it is necessary to release flood water and lift the first gate, the driving source drives the second threaded rod to rotate, and under the thread matching relationship, the connecting plate moves to the side away from the driving source, so that the guiding inclined surface on the side of the guide block with the inclined surface facing upward is on the same vertical line as the anti-falling tooth, and when the second threaded rod rotates, it will synchronously drive the first synchronous wheel to rotate; S2: When the first synchronous wheel rotates, it drives the first rotating rod to rotate through the synchronous belt and the second synchronous wheel. Since the diameter of the first synchronous wheel is larger than that of the second synchronous wheel, the second synchronous wheel will rotate more circles. The rotation of the first rotating rod will drive the first bevel gear to rotate. The first bevel gear drives the second rotating rod to rotate by meshing with the second bevel gear on the upper side, and the second bevel gear on the lower side drives the third rotating rod to rotate through the third bevel gear. The rotation of the third rotating rod will synchronously drive the moving gear to rotate. When the moving gear rotates, its position remains unchanged, which will cause the moving rack to drive the second gate to move upward, thereby opening the flood discharge outlet first. S3: After the flood outlet is opened, a part of the water flow is discharged first to reduce the water pressure on the first gate, and then the output ends on both sides of the reducer synchronously drive the first gear and the transmission rod to rotate. Here, the worm and the worm wheel are disengaged, and the transmission rod drives the second gear to rotate, so as to realize the synchronous rotation of the rope rollers on both sides and then wind up the wire rope. When the wire rope is wound, its length will be shortened and the first gate will be pulled upward through the connecting ear. When the first gate moves upward, due to the cooperation of the anti-falling tooth and the guide inclined surface of the guide block, the guide block will shrink in the direction of the support block when it moves to the position of the anti-falling tooth, so that the first gate can move upward. However, since the relative position of the guide inclined surface of the guide block is planar, the first gate cannot move downward. S4: When the first gate is lifted to a preset height, the driving source drives the second threaded rod to rotate, so that the connecting plate is restored to the top of the first gate. At this time, the middle plane of the guide block will be on the same vertical line with the anti-falling tooth. At this time, the first gate cannot move upward or downward, and the second gate will also return to the middle position. When the first gate needs to cut off the water flow, the driving source drives the second threaded rod to rotate, so that the connecting plate moves to the side close to the driving source, and the downward side of the guiding inclined surface of the guide block is on the same vertical line with the anti-falling tooth. At this time, the second gate will move downward to open the flood discharge outlet, and the output end of the reducer will rotate in the opposite direction to move the first gate downward. The bottom of the first gate will first contact the tapered bar. As the first gate continues to move downward, the first gate will press the tapered bar into the sealing groove. At the same time, the bottom of the first gate will also enter the sealing groove to complete the cutoff of the water flow. Then the driving source drives the second threaded rod to rotate again so that the second gate blocks the flood discharge outlet; S5: When the reducer fails to work, the first threaded rod is driven to rotate by the second hand wheel, and the moving block drives the worm to move through the thread matching relationship, so that the worm and the worm wheel are engaged, and then the worm is driven to rotate by rotating the first hand wheel, thereby realizing the rotation of the transmission rod and realizing the rise or fall of the first gate.

[0015] Compared with the prior art, the advantages of the present invention are: the present invention realizes double anti-fall protection for the first gate by setting an anti-fall component, and the anti-fall component realizes double anti-fall protection for the first gate through a clever combination of components such as a connecting plate, a support block, and a guide block. During the lifting or lowering of the gate, the cooperation of the guide block and the anti-fall tooth can enable the gate to move in one direction, thereby ensuring the stability of the gate during the movement; when the gate is stationary, the alignment of the planar part of the guide block with the anti-fall tooth prevents the gate from accidentally falling. By setting the anti-fall component and limiting the unidirectional movement of the gate, the safety and stability of the equipment can be significantly improved, the gate can be prevented from falling due to equipment failure or operational error, and the risk of personal injury and equipment damage can be reduced. This design simplifies the structure, reduces the difficulty and cost of maintenance, extends the service life of the equipment, and improves the controllability and reliability of operation. In addition, it can effectively prevent dangers caused by external interference or system failure, meets relevant safety standards, and improves the safety of the overall equipment and the confidence of users.

The outer surface of the third rotating rod 1214 is fixedly connected with the moving gear 1215 on both sides. The two moving gears 1215 are respectively meshed with the two moving racks 1204. The rear end of the second rotating rod 1211 is fixedly connected with the third bevel gear 1216. The upper second bevel gear 1212 is meshed with the first bevel gear 1208, and the lower second bevel gear 1212 is meshed with the third bevel gear 1216. The flood discharge assembly 12 realizes the precise control of the flood discharge port 7 through the flexible opening and closing of the second gate 1203. When flood discharge is required, the second gate 1203 is opened first to reduce the water pressure on the first gate 6 and protect the gate structure from damage. At the same time, the design of the sealing strip 1205 of the second gate 1203 also ensures its sealing performance when closed.

[0028] A method for using a gate opening and closing device with high water utilization safety, used to implement the above-mentioned gate opening and closing device with high water utilization safety, comprising: S1: First, weld the anchor assembly 10 to the side of the U-shaped frame 1, then install the device in the middle of the canal or river channel, and pour concrete on both sides of the U-shaped frame 1, anchor the anchor assembly 10 with the concrete, and complete the fixation of the device after the concrete solidifies. When it is necessary to release flood water and lift the first gate 6, the driving source 906 drives the second threaded rod 904 to rotate, and under the thread matching relationship, the connecting plate 901 moves to the side away from the driving source 906, so that the side of the guide block 913 with the inclined surface facing upward is on the same vertical line as the anti-falling tooth 14, and when the second threaded rod 904 rotates, it will synchronously drive the first synchronous wheel 907 to rotate; S2: When the first synchronous wheel 907 rotates, the first rotating rod 1207 is driven to rotate through the synchronous belt and the second synchronous wheel 1209. Since the diameter of the first synchronous wheel 907 is larger than that of the second synchronous wheel 1209, the second synchronous wheel 1209 will rotate more circles. The rotation of the first rotating rod 1207 will drive the first bevel gear 1208 to rotate. The first bevel gear 1208 drives the second rotating rod 1211 to rotate by meshing with the second bevel gear 1212 on the upper side, and the second bevel gear 1212 on the lower side drives the third rotating rod 1214 to rotate through the third bevel gear 1216. The rotation of the third rotating rod 1214 will synchronously drive the moving gear 1215 to rotate. When the moving gear 1215 rotates, its position remains unchanged, which will cause the moving rack 1204 to drive the second gate 1203 to move upward, thereby opening the flood discharge outlet 7 first. S3: After the flood outlet 7 is opened, a part of the water flow is discharged first to reduce the water pressure on the first gate 6, and then the output ends on both sides of the reducer 804 synchronously drive the first gear 805 and the transmission rod 806 to rotate. Here, the worm 818 and the worm wheel 821 are disengaged, and the transmission rod 806 drives the second gear 808 to rotate, so as to realize the synchronous rotation of the rope rollers 810 on both sides and then reel in the wire rope 812. When the wire rope 812 is reeled in, its length will be shortened and the first gate 6 will be pulled upward through the connecting ear 16. When the first gate 6 moves upward, due to the cooperation of the anti-falling tooth 14 and the guiding inclined surface of the guide block 913, the guide block 913 will shrink in the direction of the support block 902 when it moves to the position of the anti-falling tooth 14, so that the first gate 6 can move upward. However, since the relative position of the guiding inclined surface of the guide block 913 is planar, the first gate 6 cannot move downward. S4: When the first gate 6 is lifted to a preset height, the driving source 906 drives the second threaded rod 904 to rotate, so that the connecting plate 901 is restored to the top of the first gate 6. At this time, the middle plane of the guide block 913 is on the same vertical line as the anti-falling tooth 14. At this time, the first gate 6 cannot move up or down, and the second gate 1203 will also return to the middle position. When the first gate 6 needs to cut off the water flow, the driving source 906 drives the second threaded rod 904 to rotate, so that the connecting plate 901 moves to the side close to the driving source 906, and the guide block 913 guides The side of the inclined surface downward is in the same vertical line as the anti-falling tooth 14. At this time, the second gate 1203 will move downward to open the flood discharge outlet 7, and the output end of the reducer 804 will rotate in the opposite direction to move the first gate 6 downward. The bottom of the first gate 6 will first contact the tapered bar 5. As the first gate 6 continues to move downward, the first gate 6 will press the tapered bar 5 into the sealing groove 3. At the same time, the bottom of the first gate 6 will also enter the sealing groove 3 to complete the interception of the water flow. Then the driving source 906 drives the second threaded rod 904 to rotate again so that the second gate 1203 blocks the flood discharge outlet 7. S5: When the reducer 804 fails to work, the first threaded rod 815 is driven to rotate by the second hand wheel 820, and the moving block 816 drives the worm 818 to move through the threaded matching relationship, so that the worm 818 engages with the worm wheel 821, and then the worm 818 is driven to rotate by rotating the first hand wheel 819, thereby realizing the rotation of the transmission rod 806 and realizing the rising or falling of the first gate 6.

10. A method for using a gate opening and closing device with high safety for water utilization, used to implement a gate opening and closing device with high safety for water utilization as claimed in claims 1 to 9, characterized in that: include: S1: First, the anchoring assembly (10) is welded to the side of the U-shaped frame (1), and then the device is installed in the middle of a canal or a river channel, and concrete is poured on both sides of the U-shaped frame (1). The anchoring assembly (10) is used to anchor the concrete. After the concrete solidifies, the device is fixed. When it is necessary to release flood water and lift the first gate (6), the driving source (906) drives the second threaded rod (904) to rotate, and under the thread matching relationship, the connecting plate (901) moves to the side away from the driving source (906), so that the side of the guide block (913) with the inclined surface facing upward is on the same vertical line as the anti-falling tooth (14). When the second threaded rod (904) rotates, it will synchronously drive the first synchronous wheel (907) to rotate; S2: When the first synchronous wheel (907) rotates, it drives the first rotating rod (1207) to rotate through the synchronous belt and the second synchronous wheel (1209). Since the diameter of the first synchronous wheel (907) is larger than that of the second synchronous wheel (1209), the second synchronous wheel (1209) will rotate more circles. The rotation of the first rotating rod (1207) will drive the first bevel gear (1208) to rotate. The first bevel gear (1208) drives the second bevel gear (1212) on the upper side to rotate. The second rotating rod (1211) rotates, and the second bevel gear (1212) on the lower side drives the third rotating rod (1214) to rotate via the third bevel gear (1216), and the rotation of the third rotating rod (1214) synchronously drives the moving gear (1215) to rotate. Since the position of the moving gear (1215) remains unchanged during the rotation, the moving rack (1204) drives the second gate (1203) to move upward, thereby opening the flood discharge outlet (7) first; S3: After the flood discharge port (7) is opened, a portion of the water flow is discharged first to reduce the water pressure on the first gate (6), and then the output ends of the reducer (804) on both sides synchronously drive the first gear (805) and the transmission rod (806) to rotate. At this point, the worm (818) and the worm wheel (821) are disengaged, and the transmission rod (806) drives the second gear (808) to rotate, thereby achieving the synchronous rotation of the rope reeling rollers (810) on both sides to reel in the steel wire rope (812). 2) When winding, the length of the first gate (6) will be shortened, and the first gate (6) will be pulled upward through the connecting ear (16). When the first gate (6) moves upward, due to the cooperation between the anti-falling tooth (14) and the guiding inclined surface of the guide block (913), the guide block (913) will shrink in the direction of the support block (902) when it moves to the position of the anti-falling tooth (14), so that the first gate (6) can move upward. However, since the relative position of the guiding inclined surface of the guide block (913) is flat, the first gate (6) cannot move downward. S4: When the first gate (6) is lifted to a preset height, the driving source (906) drives the second threaded rod (904) to rotate, so that the connecting plate (901) is restored to the position directly above the first gate (6). At this time, the middle plane of the guide block (913) is on the same vertical line as the anti-falling tooth (14). At this time, the first gate (6) cannot move upward or downward, and the second gate (1203) is also restored to the middle position. When the first gate (6) needs to cut off the water flow, the driving source (906) drives the second threaded rod (904) to rotate, so that the connecting plate (901) moves to the side close to the driving source (906), and the guide block (913) guides the inclined surface. The downward side is in the same vertical line as the anti-falling tooth (14). At this time, the second gate (1203) will move downward to open the flood discharge outlet (7). The output end of the reducer (804) rotates in the opposite direction to move the first gate (6) downward. The bottom of the first gate (6) will first contact the conical strip (5). As the first gate (6) continues to move downward, the first gate (6) will press the conical strip (5) into the sealing groove (3). At the same time, the bottom of the first gate (6) will also enter the sealing groove (3) to complete the interception of the water flow. Then, the driving source (906) drives the second threaded rod (904) to rotate again so that the second gate (1203) blocks the flood discharge outlet (7). S5: When the reducer (804) fails to work, the first threaded rod (815) is driven to rotate by the second hand wheel (820), and the moving block (816) drives the worm (818) to move by the threaded matching relationship, so that the worm (818) and the worm wheel (821) are meshed, and then the worm (818) is driven to rotate by rotating the first hand wheel (819), thereby realizing the rotation of the transmission rod (806) and realizing the rise or fall of the first gate (6).
