Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering gate technology, and in particular to a remotely controllable water conservancy and hydropower gate. Background Technology

[0002] Hydropower gates are control facilities installed in the orifices of hydraulic structures (such as dams, reservoirs, canals, and hydropower station intakes). Their core functions are to impound water, discharge water, or regulate water level and flow. As the "moving switch" of hydraulic structures, gates precisely regulate upstream water levels and downstream flow through the opening and closing of their gate leaves to meet comprehensive needs such as flood control, power generation, irrigation, water supply, navigation, and sediment removal. Gates must operate reliably in complex environments such as high pressure, high-speed water flow, sediment erosion, and low temperatures; therefore, their structural strength, water-stopping performance, corrosion resistance, and opening / closing force design are crucial. Common gate types include lifting plane gates, arc-shaped gates rotating around a horizontal axis, and emergency gates for rapid shut-off in deep-hole accidents. Their operation is accomplished by matching hoists (such as winch-type and hydraulic types), making them key equipment for safe and efficient control in modern water conservancy projects.

[0003] In existing technologies, traditional gates generally rely on manual periodic operation for lubrication and maintenance, which is not only inefficient and wasteful of human resources, but also difficult to implement in remote or harsh environments, affecting the service life of the gate. Utility Model Content

[0004] The purpose of this utility model is to provide a remotely controllable sluice gate for water conservancy and hydropower in order to solve the above-mentioned problems. This improves the problem that traditional sluice gates generally rely on manual periodic operation for lubrication and maintenance, which is not only inefficient and wasteful of human resources, but also difficult to implement in remote or harsh environments, affecting the service life of the sluice gate.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a remotely controllable gate for water conservancy and hydropower, comprising a gate frame: sliding grooves are provided on both sides of the inner side wall of the gate frame, and pulleys are slidably connected inside the sliding grooves; an oil storage tank is provided on one side of the back of the gate frame; circular grooves are provided on both sides of the inner top wall of the gate frame, and a metering cylinder is fixedly connected inside the circular grooves; a negative pressure component is fixedly connected to the inner top wall of the metering cylinder; an oil inlet pipe is inserted into one side of the metering cylinder, and an oil outlet pipe is inserted into the other side of the inner wall of the metering cylinder; a flow guiding cavity component is provided on one side of the inner wall of the sliding grooves; and a one-way valve is provided on one side of both the oil inlet pipe and the oil outlet pipe.

[0006] Preferably, the negative pressure assembly includes a reset spring, a piston plate, and a push rod. A reset spring is fixedly connected to the middle of the top wall of the metering cylinder, a piston plate is fixedly connected to one end of the reset spring, the outer surface of the piston plate is slidably connected to the inner wall of the metering cylinder, and a push rod is fixedly connected to the middle of the surface of the piston plate.

[0007] Preferably, a through groove is provided at the center of one end of the metering cylinder, and the inner wall of the through groove is slidably connected to the surface of the push rod.

[0008] Preferably, the flow guiding cavity assembly includes a flow guiding cavity, a transition cavity, a sliding groove, and an inclined block. A flow guiding cavity is provided at an adjacent location at one end of the oil outlet pipe, a transition cavity is provided on one side of the flow guiding cavity, a sliding groove is provided at an adjacent location of the transition cavity, and an inclined block is fixedly connected to one side wall of the sliding groove.

[0009] Preferably, a gate is fixedly installed on one side of the pulley, and connectors are fixedly installed on both sides of the top surface of the gate, with a traction rope inside the connector.

[0010] Preferably, one end of the traction rope is fixedly connected to a winding rod, and both ends of the winding rod are rotatably connected to support blocks, with the bottom of the support blocks fixedly connected to the top of the gate frame.

[0011] Preferably, a motor box is fixedly connected to the middle of the top surface of the gate frame, and a dual-output shaft motor is installed inside the motor box. The output end of the dual-output shaft motor is fixedly connected to the shaft center at the end of the winding rod.

[0012] The beneficial effects of this utility model are:

[0013] 1. In this solution, through the coordinated use of the gate frame, metering cylinder, oil outlet pipe, and guide cavity assembly, during the use of the gate frame and gate, each time the gate rises, it will abut against the push rod, causing the push rod to drive the piston plate to generate negative pressure inside the metering cylinder. This allows the oil inlet pipe to transport the lubricating oil from the oil storage tank to the inside of the metering cylinder. Subsequently, when the gate is lowered, the constrained reset spring is released from its constraint and drives the piston plate to push the lubricating oil inside the metering cylinder along the oil outlet pipe to the inside of the sliding groove. The squeezed-out lubricating oil then automatically flows along the inclined block into the surface of the pulley, thus facilitating the maintenance of the pulley and gate by personnel.

[0014] 2. In this solution, through the design of the negative pressure component and the metering cylinder, during the gate's ascent, the push rod is squeezed, causing the piston plate to slide upward along the inner wall of the metering cylinder, creating a negative pressure inside the metering cylinder. This draws the lubricating oil from the oil storage tank into the metering cylinder, thus facilitating the metered use of lubricating oil by the staff and preventing excessive lubricating oil from limiting the gate's working efficiency.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] In practical implementation: such as Figures 1-5 As shown, a remotely controllable gate for water conservancy and hydropower includes a gate frame 1. Sliding grooves are provided on both sides of the inner wall of the gate frame 1, and pulleys 2 are slidably connected inside the sliding grooves. An oil storage tank 3 is provided on one side of the back of the gate frame 1. Circular grooves are provided on both sides of the inner top wall of the gate frame 1, and a metering cylinder 15 is fixedly connected inside the circular grooves. A negative pressure assembly 4 is fixedly connected to the inner top wall of the metering cylinder 15. The negative pressure assembly 4 includes a return spring 41, a piston plate 42, and a push rod 43. A return spring 41 is fixedly connected to the middle of the inner top wall of the metering cylinder 15, and a piston plate 42 is fixedly connected to one end of the return spring 41. The outer surface of the piston plate 42 is slidably connected to the inner wall of the metering cylinder 15, and a push rod 43 is fixedly connected to the middle of the surface of the piston plate 42.

[0023] In this embodiment: When the gate 8 is slowly raised during the use of the gate by the water conservancy engineering personnel, the top of the gate 8 drives the push rod 43, which causes the piston plate 42 to slide upward along the inner wall of the metering cylinder 15 and squeeze the return spring 41 to contract, so that the oil inlet pipe 5 delivers lubricating oil from the inside of the oil storage tank 3 to the inside of the metering cylinder 15, thereby facilitating the water conservancy engineering personnel to use lubricating oil in a metered manner.

[0024] like Figures 1-5 As shown, an oil inlet pipe 5 is inserted into one side of the metering cylinder 15, and an oil outlet pipe 6 is inserted into the other side of the inner wall of the metering cylinder 15. A flow guide cavity assembly 7 is provided on one side of the inner wall of the sliding groove. A one-way valve is provided on one side of both the oil inlet pipe 5 and the oil outlet pipe 6. The flow guide cavity assembly 7 includes a flow guide cavity 71, a transition cavity 72, a sliding groove 73, and an inclined block 74. A flow guide cavity 71 is provided adjacent to one end of the oil outlet pipe 6. A transition cavity 72 is provided on one side of the flow guide cavity 71. A sliding groove 73 is provided adjacent to the transition cavity 72. An inclined block 74 is fixedly connected to one side wall of the sliding groove 73.

[0025] In this embodiment: through the arrangement of the guide cavity assembly 7 and the oil outlet pipe 6, when the gate 8 slowly descends, its push rod 43 slowly slides down along the through groove, causing the constrained return spring 41 to extend. Subsequently, the return spring 41 drives the piston plate 42 to transport the lubricating oil inside the metering cylinder 15 along the oil outlet pipe 6 to the interior of the guide cavity 71. Then, it is transported along the guide cavity 71 to the interior of the transition cavity 72 and the sliding groove 73, so that the lubricating oil inside slides quickly along the inclined block 74 to the surface of the pulley 2, so that the pulley 2 can be maintained, thereby improving the working efficiency of the gate 8 and saving the resource waste of manual maintenance.

[0026] like Figures 1-5 As shown, a through groove is provided at the center of the shaft at one end of the metering cylinder 15, and the inner wall of the through groove is slidably connected to the surface of the push rod 43.

[0027] In this embodiment, the through groove is designed to allow the push rod 43 to slide smoothly along the through groove.

[0028] like Figures 1-5 As shown, a gate 8 is fixedly installed on one side of the pulley 2, and a connector 9 is fixedly installed on both sides of the top surface of the gate 8. A traction rope 10 is provided inside the connector 9. One end of the traction rope 10 is fixedly connected to a winding rod 11. Both ends of the winding rod 11 are rotatably connected to a support block 12. The bottom of the support block 12 is fixedly connected to the top of the gate frame 1.

[0029] In this embodiment: through the arrangement of the gate 8, the traction rope 10 and the winding rod 11, during the process of personnel using the gate 8, the winding rod 11 drives the gate 8 to rise or fall as it rotates forward or backward.

[0030] like Figures 1-5 As shown, a motor box 13 is fixedly connected to the middle of the top surface of the gate frame 1. A dual-output shaft motor 14 is installed inside the motor box 13. The output end of the dual-output shaft motor 14 is fixedly connected to the shaft center at the end of the winding rod 11.

[0031] In this embodiment: by setting up a dual-output shaft motor 14 and a motor box 13, when personnel need to drive the gate 8, they can drive the dual-output shaft motor 14 to drive the winding rod 11 to retract and extend the traction rope 10, thereby facilitating the remote driving of the gate 8 by personnel.

[0032] It should be noted that the model of the dual-output shaft motor 14 is YZ-160L-6-S2.

[0033] When this utility model is in use, if water conservancy engineers need to raise the gate 8, they can directly connect the power supply of the double-output shaft motor 14, which will drive the winding rod 11 to rotate. The winding rod 11 then contracts the traction rope 10, causing the traction rope 10 to drive the connecting head 9 and the gate 8 to slide upwards. This allows the pulley 2 to slide along the sliding groove, causing the gate 8 to rise rapidly. When the top of the gate 8 contacts the push rod 43, the push rod 43 slides along the through groove into the metering cylinder 15, driving the piston plate 42 to slide upwards along the inner wall of the metering cylinder 15. This causes the piston plate 42 to compress the return spring 4. The valve 1 contracts, creating negative pressure inside the metering cylinder 15. A certain amount of lubricating oil is drawn from the oil storage tank 3 and delivered to the metering cylinder 15 through the oil inlet pipe 5. When the gate 8 is lowered, the return spring 41 is released from its constraint, causing the return spring 41 to drive the piston plate 42 to extend outward. The piston plate 42 then squeezes the lubricating oil inside the metering cylinder 15 and delivers it to the oil outlet pipe 6. The drainage chamber 71 then delivers the lubricating oil to the transition chamber 72 and the sliding groove 73. Subsequently, the lubricating oil slides rapidly down the inclined block 74 and is delivered to the pulley 2, thus facilitating the function of the automatic maintenance gate 8.

[0034] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
