Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of water conservancy projects, and in particular relates to a sluice with a hazard removal function. Background Art
[0002] Sluice gates are low-head hydraulic structures built on rivers and canals that use gates to control flow and regulate water levels. Closing the gates can prevent flooding, block tides, or raise upstream water levels to meet water needs for irrigation, power generation, shipping, aquaculture, environmental protection, industry, and domestic use. Opening the gates allows floodwater, waterlogging, wastewater, or wastewater to be discharged, or water can be supplied to downstream rivers or canals. Sluice gates are widely used in water conservancy projects as structures for retaining, releasing, or drawing water.
[0003] Sluice gates must withstand immense water pressure, and are therefore typically designed to be extremely heavy, requiring a high-powered motor to operate. However, when a motor is required to operate the gate, it can easily become stuck during movement, causing the motor's power to increase instantaneously, potentially leading to motor overload and burnout. These stuck conditions are primarily caused by the following: 1. The impact of the water flow exerts force on one side of the gate, increasing friction between the gate and the retaining groove; 2. Small stones or other foreign objects entering the retaining groove change the direction and magnitude of the force; 3. The direction of the cable tension deviates significantly from the direction of gravity on the gate, causing the gate to tilt significantly. Shaking the gate can resolve this stuck condition, but the gate's weight, location, and structure make it difficult to resolve manually. The consequences of this in an emergency requiring the gate to release water are immeasurable. In addition, debris such as stones and branches often cling to the gate groove at the bottom of the gate, resulting in a gap between the bottom of the gate and the gate groove, making it impossible for the gate to completely close the gate mouth and thus completely block the water system. If this problem occurs during flood prevention and control, it will inevitably pose a major safety hazard.
[0004] Therefore need a kind of sluice to solve above-mentioned problem. Summary of the Invention

A sealed cavity is formed between the side walls of the limiting groove 4; the side wall of the limiting groove 4 located on the side of the gate is provided with a receiving groove 7 extending into the wall 1, and a sealing plate 8 for the sealing groove 20 is slidably provided in the receiving groove 7; an air cylinder 9 is also provided in the wall 1, and a piston plate 11 is slidably provided in the air cylinder 9, and the piston plate 11 is connected to the sealing plate 8 through a push-pull rod 10; an air pipe 12 is also provided in the wall 1, one end of the air pipe 12 is connected to the sealed cavity, the other end of the air pipe 12 is sealed, and the air pipe 12 is connected to the air cylinder 9 through a connecting pipe 13.
[0026] The above-mentioned lifting device 3 is used to lift or lower the gate plate 2, and includes a pair of support frames 3-1 fixed on the wall 1, and a rotating shaft 3-3 is rotatably provided between the pair of support frames 3-1. The rotating shaft 3-3 is driven to rotate by a driving motor 3-2. An annular plate 3-7 is fixed on the rotating shaft 3-3, and a rope drum 3-4 is provided on the periphery of the rotating shaft 3-3. The rope drum 3-4 is provided with multiple connecting rods 3-6 that slide through the annular plate 3-7. A pull rope 3-5 is wound around the rope drum 3-4, and the free end of the pull rope 3-5 is fixedly connected to the lifting ear 26 provided on the top of the gate plate 2.
[0027] A first slide groove 14 extending into the interior is provided at the bottom of the gate plate 2, and a slider 15 is slidably provided in the first slide groove 14. Second slide grooves extending into the interior are provided on the left and right sides of the gate plate 2, and a shovel plate 16 is slidably provided in the second slide groove. A push rod 17 extending into the first slide groove 14 is fixed on the side of the shovel plate 16, and the ends of the two push rods 17 are provided with inclined surfaces adapted to the left and right sides of the slider 15. A tension spring 18 is provided on the push rod 17 to apply tension to the shovel plate 16, and the two ends of the tension spring 18 are respectively fixedly connected to the shovel plate 16 and the inner wall of the second slide groove.
[0028] In order to prevent impurities such as stones from remaining on the surface of the bottom plate 5, the cross-sectional profile of the upper half of the bottom plate 5 is in an inverted V shape, and the bottom of the gate plate 2 is provided with a V-shaped groove for the upper half of the bottom plate 5.
[0029] It should be noted that when the slider 15 is pushed to the uppermost position by the bottom plate 5, the outer edge of the shovel plate 16 is flush with the side wall of the side limit groove 4 and the outer edge of the sealing plate 8; the bottom of the limit groove 4 located at the lower part of the gate is provided with a plurality of limit seats 19 for the bottom plate 5. When the bottom plate 5 is in contact with the limit seats 19, the sealing plate 8 extends into the sealing groove 20 and the corresponding inclined surfaces of the sealing plate 8 and the shovel plate 16 are just in contact with each other. The lowest position of the inclined surface of the shovel plate 16 is flush with the bottom edge of the receiving groove 7.
[0030] To ensure that the gate plate 2 can move up and down stably, a guide structure is provided on the front and rear sides of the gate plate 2; the guide structure includes a guide hole 21, a guide rod 223-6 is slidably provided in the guide hole 21, the outer end of the guide rod 22 is provided with a mounting frame, a guide wheel 23 is rotatably provided on the mounting frame, a limit block 24 is provided on the guide rod 22, a limiting groove for the limit block 24 is provided in the wall 1, and a tension spring for applying tension to the limit block 24 is also provided on the outside of the guide rod 22; the side wall of the limit groove 4 is provided with a vertical guide groove for the guide wheel 23.
[0031] To facilitate positioning of the gate plate 2, a positioning plate is provided at the end of the rotating shaft 3-3. The positioning plate has a threaded through hole, into which a positioning bolt 3-9 is screwed. A plurality of positioning holes corresponding to the positioning bolts 3-9 are provided on the support frame 3-1 near the positioning plate 3-8. The specific working principle of the present invention is as follows: When the gate plate 2 is raised, the control device controls the drive motor 3-2 to rotate forward, which drives the rotating shaft 3-3 to rotate, and the pull rope 3-5 is wound around the rope drum 3-4. It should be noted that because the pull rope 3-5 is coiled close to the previous coil, a certain lateral force is applied to the previous coil during the coiling process. As a result, the guide rod 223-6 on the entire rope drum 3-4 is displaced relative to the annular plate 3-7, thereby ensuring that the pull rope 3-5 remains substantially vertical. When the gate plate 2 is lowered, the control device controls the drive motor 3-2 to rotate in the reverse direction.
[0032] During the falling process of the gate plate 2, when the slider 15 contacts the bottom plate 5, the bottom plate 5 squeezes the slider 15 to move upward and pushes the push rod 17 to move to the outside of the gate plate 2, so that the shovel plate 16 also moves to the outside of the second slide groove. When the gate plate 2 is just pressed on the bottom plate 5, the shovel plate 16 moves to the outermost edge. At this time, the outer edge of the shovel plate 16 is flush with the side wall of the side limit groove 4 and the outer edge of the sealing plate 8; when the gate plate 2 continues to move downward, the bottom plate 5 moves downward, and the gas in the sealing chamber enters the air cylinder 9 through the air pipe 12 and pushes the piston plate 11 to move, thereby pushing the sealing plate 8 to move outward and gradually extend into the sealing groove 20. When the bottom plate 5 is in contact with the limit seat 19, the corresponding inclined surfaces of the sealing plate 8 and the shovel plate 16 are just in contact, and the lowest position of the inclined surface of the shovel plate 16 is flush with the bottom edge of the receiving groove 7.
[0033] When the gate plate 2 is raised, under the action of the elastic telescopic rod 6, the base plate 5 moves up, and the gas in the gas cylinder 9 enters the sealing chamber through the air pipe 12. Under the action of negative pressure, the piston plate 11 moves away from the sealing plate 8, and the sealing plate 8 is retracted into the receiving groove 7. When the gate plate 2 is separated from the base plate 5, the slider 15 starts to move downward. Under the action of the tension spring 18, the shovel plate 16 moves into the second slide groove until the gate plate 2 is raised to the specified position, and the positioning bolts 3-9 are inserted into the positioning holes.
[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solutions of the present invention. They should all be included in the scope of the technical solutions claimed for protection by the present invention.
