Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of water conservancy projects, and in particular to a biaxial staggered shearing type integrated pump gate. Background Art
[0002] A pump-gate is a hydraulic engineering device that combines the functions of a pump and a gate. It is widely used in reservoirs, rivers, pumping stations, and urban drainage systems. It controls and regulates water flow through the pump's propulsion, coordinated with the opening and closing of gates. Pump-gates play a vital role in hydraulic engineering, particularly in responding to water level fluctuations, regulating flow, and preventing floods. The operating principle of a pump-gate is based on the dual functions of a pump and a gate. As the water level rises or falls, the pump-gate automatically adjusts the pump's output flow, coordinating with the opening and closing of the gate to direct and control water flow. The pump's action extracts or discharges water from the water body. When the water level reaches the set value, the gate automatically opens or closes to ensure system balance.
[0003] However, existing equipment often encounters the following problems during use:
[0004] (1) During water level adjustment and pump gate system operation, aquatic plants and debris often cause the pump body to become clogged, affecting water flow and the normal operation of the pump, necessitating frequent shutdowns for maintenance.
[0005] (2) The traditional pump gate system may not be able to raise or lower the gate smoothly due to water level changes, sediment accumulation or aquatic weed accumulation, which may cause the gate to be stuck. Summary of the Invention

The force shell pushes the force plate, and the force plate presses down the oblique opening and closing plate of the bottom opening and closing mechanism. The opening and closing plate is hinged to the gate, so it will gradually retract to avoid being blocked by sediment, thereby ensuring that the bottom of the gate can rise smoothly.

[0050] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.
[0051] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "disposed," "arranged," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.
[0052] like Figure 1-7 As shown, the present invention provides a double-axis staggered shearing integrated pump gate, which includes a gate 1, a pump body 2, a submersible motor 3, a main rotary gear 4, a transmission gear 5, a shear mechanism 6, a horizontal gear 61, a shear gear 62, a shear rod 63 and a rotary vane 64.
[0053] The pump body 2 is inserted through the bottom of the gate 1. The shape of the water outlet of the pump body 2 is the same as the fan blade water inlet 18, and the water outlet of the pump body 2 is axially fixed to the submersible motor 3. The chamber inside the pump body 2 is equipped with the submersible motor 3. The main rotating gear 4 is set at the output end of the submersible motor 3, and the transmission gear 5 is vertically meshed with the main rotating gear 4. The pump body 2 is inserted through the bottom of the gate 1, and the water outlet of the pump body 2 is axially fixed to the submersible motor 3, ensuring smooth flow of water and avoiding structural instability. The design of the main rotating gear 4 and the transmission gear 5 enables mechanical transmission through the rotation of the submersible motor 3, driving the action of the shear mechanism 6. The vertical meshing of the main rotating gear 4 and the transmission gear 5 ensures the efficiency and accuracy of power transmission.
[0054] In the present invention, the shearing mechanism 6 is provided with two groups, and the two groups of shearing mechanisms 6 are symmetrically arranged on both sides of the transmission gear 5. The shearing mechanism 6 includes a horizontal gear 61, a shearing gear 62, a shearing rod 63 and a rotary vane 64. The horizontal gear 61 is located on one side of the side wheel surface of the transmission gear 5. The shearing gear 62 is vertically meshed with the horizontal gear 61. The shearing rod 63 is arranged on the axis of the shearing gear 62. The distal end of the shearing rod 63 passes through the pump body waterproof shell 7 and is provided with a rotary vane 64. The penetration position of the shearing rod 63 is the arc of the pump body waterproof shell 7. At the shaped end, two rotor blades 64 are arranged in a straight line, with the central axis angle of the two sets of shearing gears 62 being 30°. The rotor blades 64 are made of stainless steel. The horizontal gear 61 of each set of shearing mechanisms 6 meshes with the transmission gear 5, and the transmission gears 5 of the two sets of shearing mechanisms 6 mesh with each other. The two sets of shearing mechanisms 6 are arranged on either side of the transmission gear 5, and the central axis angle of the gears is 30°. This allows the rotor blades 64 to produce an interlaced vortex effect, effectively cutting aquatic plants or other underwater debris. The meshing of the shearing gear 62 and the horizontal gear 61 enables the shearing gear 62 to rotate and drive the shear rod 63, which in turn drives the rotor blades 64 to rotate and form a vortex. The rotor blades 64 are made of stainless steel, which is corrosion-resistant and suitable for long-term underwater operation. The dual-axis staggered design staggers the relative positions of the rotor blades 64, and the vortices of the rotor blades 64 interact to form a shear force, effectively preventing blockage by aquatic plants and other debris, ensuring stable operation of the system. This design is particularly suitable for environments where aquatic plants grow vigorously. With the help of vortex, the aquatic plants are cut into small pieces, reducing blockage of the pump body 2 and extending the service life of the system.
[0055] The pump body waterproof shell 7 is sleeved on the output end of the submersible motor 3. One end of the pump body waterproof shell 7 is arc-shaped. The main rotating gear 4, the transmission gear 5 and the shearing mechanism 6 are all arranged inside the pump body waterproof shell 7 to provide protection for the gear set.
[0056] In the present invention, the lifting cylinder 8 is horizontally arranged on the top surface of the gate 1. The output end of the lifting cylinder 8 is connected to the fixed shell 9. The top surface of the booster plate 10 is fixedly connected to the fixed shell 9. The booster plate 10 is a U-shaped frame. The booster plate 10 adopts a U-shaped frame design and can move smoothly under the guidance of the guide rail 11. The design of the step chute 12 and the slide rod 13 brings better movement control. The guide rail 11 is located on both sides of the booster plate 10. The guide rail 11 extends horizontally in a straight line. The two sides of the booster plate 10 are penetrated by the step chute 12. The step chute 12 includes a one-level step structure with a height difference of 40 cm, and the step shape is an inclined step. The two ends of the slide rod 13 are passed through the two groups of step chute 12. The passing end of the slide rod 13 slides with the step chute 12. The structure of the step chute 12 allows the slide rod 13 to descend or rise step by step, ensuring the smooth transmission of force. The force-applying housing 14 is sleeved onto the shaft of the slide rod 13. The bottom of the force-applying plate 15 is fixedly connected to the top of the force-applying housing 14. Hinge slots 16 are provided at the four corners of the gate 1. A lifting cylinder 8 is positioned transversely on the top of the gate 1. The thrust from the cylinder's output drives the movement of the fixed housing 9 and the booster plate 10. The cylinder's force transmission mechanism is designed to effectively drive the entire structure up and down.
[0057] In the present invention, two sets of opening and closing mechanisms 17 are located on either side of the gate 1. The opening and closing mechanisms include linkage plates 171 and oblique opening and closing plates 172. At least two linkage plates 171 are provided, and the tops of the two linkage plates 171 are fixedly connected to the top surface of the force-applying plate 15. The oblique opening and closing plates 172 are obliquely arranged on the bottom side of the gate 1, and the tops of the oblique opening and closing plates 172 are hinged to the hinge groove 16 of the gate 1. The opening and closing mechanism achieves precise opening and closing of the gate 1 through the cooperation of the linkage plates 171 and the oblique opening and closing plates 172. The linkage plates 171 are connected to the force-applying plate 15 to ensure the synchronization of the opening and closing plates, so that the gate 1 will not be blocked by underwater sediment when it is opened. The oblique opening and closing plates 172 are designed on the bottom side of the gate 1, and their tops are connected to the hinge groove 16. The oblique shape of the plate allows the plate to avoid interference from sediment such as water plants during lifting and lowering, ensuring that the gate 1 can be raised and lowered smoothly.
[0058] In the present invention, the fan blade water inlet 18 is fixed to one end of the pump body 2, and the fan blade water inlet 18 is located in the extension direction of the output end of the submersible motor 3; the water outlet of the pump body 2 has the same shape as the fan blade water inlet 18, and the water outlet of the pump body 2 is axially fixed to the submersible motor 3, and the side wheel surface of the pump body waterproof shell 7 is connected to the inner cavity of the pump body 2 through the fixed bracket 19, and the central axes of the main rotating gear 4 and the transmission gear 5 are both penetrated by the corresponding rotating shaft bracket 20, and the penetrating end of the rotating shaft bracket 20 is fixedly connected to the inner wall of the pump body waterproof shell 7.
[0059] It should be noted that the dual-axis staggered shearing integrated pump gate designed by the present invention, when in use, if it is necessary to balance or adjust the water levels on both sides of the gate 1, start the submersible motor 3, and the output end of the motor rotates to rotate the main rotary gear 4, and the main rotary gear 4 drives the transmission gear 5 that is vertically meshed with it, and the transmission gear 5 drives a group of shearing mechanisms 6 on its side wheel surface. The horizontal gear 61 arranged flush with the transmission gear 5 in the shearing mechanism 6 is driven by it, and the horizontal gear 61 will drive the shearing gear 62 perpendicular to itself and the horizontal gear 61 of another group of shearing mechanisms 6. The two groups of shearing mechanisms 6 operate in the same way, that is, the shearing gear 62 rotates to drive the shear rod in its axial position. 63. The shear rod 63 rotates axially toward the center, driving one end of the shear rod 63 away from the shaft waterproof shell. Two rotary blades 64 are provided at the penetration end of the shear rod 63. The two rotary blades 64 of the two sets of shearing mechanisms 6 rotate to form a vortex. Since the extended lines of the axes of the shear gears 62 of the two sets of shearing mechanisms 6 are at an acute angle, the positions of the two sets of rotary blades 64 are staggered. The cross vortex formed by the staggered rotating rotary blades 64 will form a shear force. At this time, the water plants and debris attracted by the vortex are cut into slices by the staggered rotating rotary blades 64 after passing through the fan water inlet 18 of the pump body 2, and finally flow to the discharge port for discharge through the gap between the submersible motor 3 and the inner wall of the pump chamber. No blockage will occur during the whole process.
[0060] After the water level adjustment is completed, if the gate 1 needs to be raised, in order to ensure that the bottom of the gate 1 does not generate rising pressure due to the accumulation of sediments such as algae, the lifting cylinder 8 is started, and the output end of the cylinder pops out to drive the fixed shell 9. After receiving the thrust, the fixed shell 9 drives the booster plate 10 at the bottom, and the booster plate 10 slides to the side away from the cylinder. The step chutes 12 opened on both sides of the booster plate 10 will slide together, and the sliding rod 13 originally at the top notch of the step chute 12 will gradually move to the lower step due to the thrust and the guidance of the step chute 12. The bottom end of the chute 12 slides, and the slide rod 13 moves downward, driving the force shell 14 of the sleeve rod body to move downward together. The force shell 14 moves downward, driving the force plate 15 on the top surface. Finally, the force plate 15 pushes down the two sets of opening and closing mechanisms 17 on the bottom surface. Here, taking one set of opening and closing mechanisms as an example, the two linkage plates 171 on one side of the gate 1 are pressed down by the force plate 15, driving the oblique opening and closing plates 172 at the bottom end. Because the top of the opening and closing plates is hinged to one side of the bottom of the gate 1, the oblique opening and closing plates 172 will gradually become flush with the side wall of the gate 1 until they are attached. In this way, the oblique opening and closing plates 172, which were originally on the bottom of the water and had sediment in contact with the outer wall, will be retracted inward and will not be blocked by the sediment. The original bottom of the gate 1 can also be raised and lowered normally because it is in contact with the sediment.
[0061] Although the embodiments of the present invention have been shown and described, it will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations may be made to these embodiments without departing from the principles and spirit of the invention, and the scope of the invention is defined by the appended claims and their equivalents.
