[0002] A gate is a control facility used to close and open a water discharge (release) channel. It is an important part of hydraulic structures and can be used to intercept water flow, control water level, regulate flow rate, discharge sediment and floating objects, etc. Classified by production materials, there are mainly wooden gates, wooden panel steel frame gates, cast iron gates, reinforced concrete gates, and steel gates. Classified by the relative position of the gate top and the horizontal plane, there are mainly open-top gates and submerged gates. Classified by working nature, there are mainly working gates, emergency gates, and maintenance gates. Classified by the gate opening and closing method, there are mainly gates operated by machinery and hydraulic automatic gates that control opening and closing by utilizing the change in water pressure on the gate when the water level rises and falls.

[0014] A usage method of a gate opening and closing device with high water utilization safety, which is used to implement the above-mentioned gate opening and closing device with high water utilization safety, includes:

[0015] S1: First, weld the anchoring assembly to the side of the U-shaped frame, then install the device in the middle of the water channel or river course, and pour concrete on both sides of the U-shaped frame. Anchor it through the anchoring assembly and the concrete. After the concrete solidifies, the fixation of the device is completed. When it is necessary to lift the first gate for flood discharge, the driving source drives the second threaded rod to rotate. Under the screw-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 guiding block with the inclined surface facing upward is on the same vertical line as the anti-falling teeth. When the second threaded rod rotates, it will drive the first synchronous pulley to rotate synchronously;

[0016] S2: When the first synchronous pulley rotates, it drives the first rotating rod to rotate through the synchronous belt and the second synchronous pulley. Since the diameter of the first synchronous pulley is larger than that of the second synchronous pulley, the second synchronous pulley will rotate more turns. 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 will drive 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, since its position remains unchanged, it will cause the moving rack to drive the second gate to move upward, thereby opening the flood discharge port one step ahead.

[0017] S3: After the flood discharge port is opened, a part of the water flow is discharged first to reduce the water pressure on the first gate. Then, the output ends on both sides of the speed reducer synchronously drive the first gear and the transmission rod to rotate. Here, the worm and the worm gear are disengaged, and the transmission rod will drive the second gear to rotate, thereby realizing the synchronous rotation of the rope winding rollers on both sides and winding the steel wire rope. When the steel wire rope is wound, since its length will become shorter, it will pull the first gate upward through the connecting ear. When the first gate moves upward, due to the cooperation of the anti-falling teeth and the guiding inclined surface of the guiding block, when the guiding block moves to the position of the anti-falling teeth, it will contract towards the supporting block so that the first gate can move upward. And since the relative position of the guiding inclined surface of the guiding block is flat, the first gate cannot move downward.

[0018] S4: When the first gate is lifted to the preset height, the driving source drives the second threaded rod to rotate, so that the connecting plate returns directly above the first gate. At this time, the middle plane of the guiding block will be on the same vertical line as the anti-falling teeth. At this time, the first gate cannot move upward or downward. At the same time, 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 towards the side close to the driving source. The downward side of the guiding inclined surface of the guiding block is on the same vertical line as the anti-falling teeth. At this time, the second gate will move downward to open the flood discharge port. When the output end of the speed reducer rotates in the reverse direction to make the first gate move downward, the bottom of the first gate will abut against the tapered bar first. 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 cut-off of the water flow. Subsequently, the driving source drives the second threaded rod to rotate again to make the second gate block the flood discharge port.

[0019] S5: When the speed reducer cannot work, the first threaded rod is driven to rotate by the second handwheel. Through the thread matching relationship, the moving block drives the worm to move, so that the worm meshes with the worm gear. Then, the worm is driven to rotate by rotating the first handwheel, thereby realizing the rotation of the transmission rod and realizing the rise or fall of the first gate.

[0020] Compared with the prior art, the advantages of the present invention are as follows: By providing a falling prevention component, through the ingenious combination of components such as a connecting plate, a support block, and a guiding block, the present invention realizes double falling prevention protection for the first gate. During the lifting or lowering process of the gate, the cooperation between the guiding block and the falling prevention teeth enables the gate to move unidirectionally, ensuring the stability of the gate during movement; when the gate is stationary, the alignment of the flat part of the guiding block with the falling prevention teeth prevents the accidental falling of the gate. By providing a falling prevention component and restricting the unidirectional movement of the gate, the safety and stability of the equipment can be significantly improved, preventing the gate from falling due to equipment failure or operation errors, reducing the risk of personal injury and equipment damage. This design simplifies the structure, reduces the maintenance difficulty and cost, 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 failures, meets relevant safety standards, and enhances the overall safety of the equipment and the confidence of users.

[0059] Referring to Figure 11 、 Figure 12 and Figure 15 As shown in the figure, the flood discharge component 12 includes a first rotating rod 1207, two first connecting seats 1210 and two second connecting seats 1213. The first rotating rod 1207 is rotatably connected to the upper end at the rear of the first gate 6. Two groups of first connecting seats 1210 are fixedly connected to the rear end on the left side of the first gate 6. Two groups of second connecting seats 1213 are fixedly connected to the left and right sides in the middle of the first gate 6. On the surface of the first rotating rod 1207, a first bevel gear 1208 is fixedly connected. At the end of the first rotating rod 1207, a second synchronous wheel 1209 is fixedly connected. The second synchronous wheel 1209 is in transmission connection with the first synchronous wheel 907 through a synchronous belt. A second rotating rod 1211 is rotatably connected between two groups of first connecting seats 1210. At the upper and lower ends of the second rotating rod 1211, second bevel gears 1212 are fixedly connected. A third rotating rod 1214 is rotatably connected between two groups of second connecting seats 1213. On the outer surface of the third rotating rod 1214, moving gears 1215 are fixedly connected to both the left and right sides. The two moving gears 1215 are respectively engaged with two groups of moving racks 1204. At the rear end of the third rotating rod 1214, a third bevel gear 1216 is fixedly connected. The upper second bevel gear 1212 is engaged with the first bevel gear 1208, and the lower second bevel gear 1212 is engaged with the third bevel gear 1216. Through the flexible opening and closing of the second gate 1203, the flood discharge component 12 realizes the precise control of the flood discharge port 7. When flood discharge is required, the second gate 1203 opens first, reducing the water pressure on the first gate 6 and protecting the gate structure from damage. At the same time, the design of the sealing rubber strip 1205 of the second gate 1203 also ensures its sealing performance when closed.

[0060] A usage method of a high - safety gate opening and closing device for water utilization, used to implement the above - mentioned high - safety gate opening and closing device for water utilization, includes:

[0061] S1: First, weld the anchoring assembly 10 to the side of the U-shaped frame 1. Then, install the device in the middle of a water channel or a river course, and pour concrete on both sides of the U-shaped frame 1. Anchor it through the anchoring assembly 10 and the concrete. After the concrete solidifies, the fixation of the device is completed. When it is necessary to release flood and lift the first gate 6, the driving source 906 drives the second threaded rod 904 to rotate. Under the screw-thread engagement relationship, the connecting plate 901 moves to the side away from the driving source 906, so that the guiding slope on the side with the inclined surface facing upward of the guiding block 913 is on the same vertical line as the anti-falling teeth 14. When the second threaded rod 904 rotates, it will synchronously drive the first synchronous pulley 907 to rotate;

[0062] S2: When the first synchronous pulley 907 rotates, it drives the first rotating rod 1207 to rotate through the synchronous belt and the second synchronous pulley 1209. Since the diameter of the first synchronous pulley 907 is larger than that of the second synchronous pulley 1209, the second synchronous pulley 1209 will rotate more circles. The rotation of the first rotating rod 1207 drives the first bevel gear 1208 to rotate. The first bevel gear 1208 drives the second rotating rod 1211 to rotate through meshing with the upper second bevel gear 1212. The lower second bevel gear 1212 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, since its position remains unchanged, the moving rack 1204 will drive the second gate 1203 to move upward, thus opening the flood discharge port 7 one step ahead;

[0063] S3: After the flood discharge port 7 is opened, a part of the water flow is discharged first to reduce the water pressure on the first gate 6. Then, the output ends on both sides of the speed reducer 804 synchronously drive the first gear 805 and the transmission rod 806 to rotate. Here, the worm 818 and the worm gear 821 are disengaged from meshing, and the transmission rod 806 drives the second gear 808 to rotate, so as to realize the synchronous rotation of the rope winding rollers 810 on both sides and wind up the steel wire rope 812. When the steel wire rope 812 is wound up, since its length will become shorter, it will pull the first gate 6 to move upward through the connecting ear 16. When the first gate 6 moves upward, due to the cooperation between the anti-falling teeth 14 and the guiding slope of the guiding block 913, when the guiding block 913 moves to the position of the anti-falling teeth 14, it will contract towards the supporting block 902 so that the first gate 6 can move upward. Since the guiding slope of the guiding block 913 is planar in the relative position, the first gate 6 cannot move downward;

[0064] S4: After the first gate 6 is lifted to a preset height, the drive source 906 drives the second threaded rod 904 to rotate, causing the connecting plate 901 to return directly above the first gate 6. At this time, the middle plane of the guide block 913 will be on the same vertical line as the anti-falling teeth 14. At this time, the first gate 6 cannot move upward or downward. At the same time, the second gate 1203 will also return to the middle position. When the first gate 6 needs to cut off the water flow, the drive source 906 drives the second threaded rod 904 to rotate, causing the connecting plate 901 to move toward the side close to the drive source 906. The downward-facing side of the guiding inclined surface of the guide block 913 is on the same vertical line as the anti-falling teeth 14. At this time, the second gate 1203 will move downward to open the flood discharge port 7. When the output end of the speed reducer 804 rotates in the reverse direction to cause the first gate 6 to move downward, the bottom of the first gate 6 will first come into contact with 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 cut-off of the water flow. Subsequently, the drive source 906 drives the second threaded rod 904 to rotate again to cause the second gate 1203 to block the flood discharge port 7;

[0065] S5: When the speed reducer 804 fails to work, the first threaded rod 815 is driven to rotate by the second handwheel 820. Through the threaded engagement relationship, the moving block 816 drives the worm 818 to move, causing the worm 818 to engage with the worm gear 821. Then, the worm 818 is driven to rotate by turning the first handwheel 819, thereby causing the transmission rod 806 to rotate and realizing the upward or downward movement of the first gate 6.

The second gate (1203) is fixedly connected to a sealing strip (1205) on one side close to the first gate (6).

7. 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 claim 6, 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).
